Description

The present invention relates to a fixed body.

Patent document 1 discloses a fixed body for fixing an installation body installed on an installation surface to the installation surface. The fixed body has a horizontal support plate, a vertical support plate, and a vertical movable plate. The horizontal support plate is fixed to the installation surface. The vertical support plate is fixed to a side surface of the installation body. The vertical movable plate is connected to both the horizontal support plate and the vertical support plate. The horizontal support plate and the vertical support plate are integrated via the vertical movable plate.

The vertical support plate and the vertical movable plate are connected by a bolt. The vertical support plate has a female threaded hole into which the bolt is screwed. The vertical movable plate has a long hole through which the bolt is inserted at the portion connected to the vertical support plate. The longitudinal direction of the long hole extends in a direction perpendicular to the installation surface. Therefore, when the bolt is loosened, the shaft of the bolt can move within the long hole in a direction perpendicular to the installation surface. In other words, the vertical support plate can be moved relative to the vertical movable plate in a direction perpendicular to the installation surface without removing the bolt to release the connection between the vertical support plate and the vertical movable plate. By moving the vertical support plate relative to the vertical movable plate, the fixed position of the vertical support plate relative to the installation body can be adjusted.

JP 2012-233549 A

In such a fixed body, when the vertical support plate is moved relative to the vertical movable plate, if the bolt shaft comes into contact with the inner surface that defines the long hole and that is aligned in the longitudinal direction of the long hole, smooth relative movement is hindered. For this reason, from the viewpoint of enabling smooth relative movement, it is preferable to have a wide gap between the inner surface that defines the long hole and the bolt shaft, which is aligned in the longitudinal direction of the long hole. However, if the gap is wide, the vertical movable plate may rotate together with the bolt when the bolt is rotated to tighten the bolt. If the vertical movable plate rotates together, there is a risk that the horizontal support plate connected to the vertical movable plate may rise up from the installation surface. If the horizontal support plate rises up from the installation surface, the fixed state between the installation surface and the horizontal support plate will be weakened.

The fixing body for solving the above problem is a fixing body for fixing an installation body to an installation surface, the fixing body comprising: a first base having a first fixing part fixed to the installation surface and a first connecting part in which a first bolt hole through which a bolt is inserted; and a second base having a second fixing part that is coupled to the installation body or presses the installation body toward the installation surface and a second connecting part in which a second bolt hole through which the bolt is inserted, the first base and the second base being connected by a fastening member including the bolt inserted into the first bolt hole and the second bolt hole in a state in which the first connecting part and the second connecting part are overlapped, the axial direction of the first bolt hole and the second bolt hole extends in a first direction in which the first connecting part and the second connecting part overlap, the first bolt hole and the second bolt hole are connected by a fastening member including the bolt inserted into the first bolt hole and the second bolt hole in a state in which the first connecting part and the second connecting part are overlapped ... At least one of the first and second bolt holes is an elongated hole, one of the first and second connecting parts has a protrusion protruding in the first direction, and the other of the first and second connecting parts has a protrusion insertion part into which the protrusion is inserted, and when the direction that is the longitudinal direction of the elongated hole and perpendicular to the first direction is defined as a second direction, and the direction that is the lateral direction of the elongated hole and perpendicular to the first and second directions is defined as a third direction, the protrusion insertion part is an elongated hole whose longitudinal direction extends in the second direction and whose lateral direction extends in the third direction, and the protrusion insertion part or the protrusion has a distance shortening part that shortens the shortest distance between the inner surface that defines the protrusion insertion part and the outer surface of the protrusion in the third direction as the amount of insertion of the protrusion into the protrusion insertion part increases.

In the fixed body, a portion of an outer surface of the projection that constitutes the distance-reducing portion may extend in the second direction.
In the fixed body, a wide portion that constitutes the distance-reducing portion and that has a dimension in the third direction larger than that of a tip end side of the protrusion may be formed on the base end side of the protrusion.

In the fixed body, a dimension of the wide portion in the third direction may gradually increase from the tip end to the base end of the projection.
In the above-mentioned fixed body, when the opening in the protrusion insertion portion through which the tip of the protrusion passes when the protrusion is inserted into the protrusion insertion portion is defined as an insertion side opening, the dimension of the base end of the protrusion in the third direction may be the same as or larger than the dimension of the insertion side opening in the third direction, and the dimension of the tip side of the protrusion in the third direction may be smaller than the dimension of the insertion side opening in the third direction.

In the fixed body, a plurality of the protrusions may be provided in the second direction.
In the fixed body, a dimension in the second direction of a portion of an outer surface of the projection that constitutes the distance-reducing portion may be larger than a dimension of the projection in the third direction.

In the fixed body, the first bolt hole may also serve as the protrusion insertion portion.
In the fixed body, the first bolt hole may be provided separately from the protrusion insertion portion.

In the fixed body, the bolt and the projection may be aligned in a straight line in the third direction.
In the fixed body, the first connecting portion may have a plurality of the protrusion insertion portions in the third direction, and the second connecting portion may have a plurality of the protrusions in the third direction.

In the fixed body, the protrusion insertion portion may be a through hole that passes through the first connecting portion or the second connecting portion in the first direction.
In the fixed body, the first fixed portion and the second fixed portion may face each other in the second direction.

The present invention allows smooth relative movement of the second connecting part with respect to the first connecting part while suppressing co-rotation of the connecting parts.

An embodiment of the fixed body will be described below with reference to FIGS.
As shown in FIG. 1 and FIG. 2, an installation body S is installed on an installation surface F. The installation surface F is, for example, a floor surface. The installation body S is, for example, a shelf. The installation body S has a plurality of shelf boards 100 and four support columns 101. Note that in FIG. 1, two shelf boards 100 and three support columns 101 are illustrated. The plurality of shelf boards 100 are supported by the four support columns 101. The plurality of shelf boards 100 are arranged at intervals in the vertical direction. Each shelf board 100 has a rectangular shape. Each shelf board 100 has an upper surface 100a, a lower surface 100b, and four side surfaces 100c. The lower surface 100b of the shelf board 100 located at the lowest level among the plurality of shelf boards 100 is separated from the installation surface F.

<<Fixed body>>
The fixing body 10 is for fixing the installation body S, which is installed on the installation surface F, to the installation surface F. By fixing the installation body S to the installation surface F with the fixing body 10, the earthquake resistance of the installation body S is improved.

In the example of use of the fixed bodies 10 shown in FIG. 1, four fixed bodies 10 are used for the shelf board 100 located at the bottom of a plurality of shelves 100. Note that three fixed bodies 10 are shown in FIG. 1. Of the four fixed bodies 10, two fixed bodies 10 are arranged at one end of the shelf board 100 in the longitudinal direction so as to sandwich the shelf board 100 in the short direction. Of the four fixed bodies 10, the other two fixed bodies 10 are arranged at the other end of the shelf board 100 in the longitudinal direction so as to sandwich the shelf board 100 in the short direction. Note that the method of fixing the installation body S to the installation surface F by the fixed bodies 10 will be described later.

As shown in Figures 3 and 4, the fixed body 10 includes a first base 11, a second base 12, and fastening members. The fastening members connect the first base 11 and the second base 12. In this embodiment, the fastening members are three bolts B, three flat washers W1, and three spring washers W2.

<First Base>
The first base 11 has a first fixing portion 13 and a first connecting portion 14. The first fixing portion 13 is a portion that is fixed to the installation surface F. The first connecting portion 14 is a portion that is connected to the second base 12.

The first fixing portion 13 in this embodiment is composed of a fixing plate 31 and an adhesive mat 32 .
The fixed plate 31 is a rectangular plate. The fixed plate 31 has a first surface 31a and a second surface 31b. The first surface 31a and the second surface 31b are surfaces perpendicular to the plate thickness direction of the fixed plate 31. The second surface 31b is a surface located opposite to the first surface 31a in the plate thickness direction of the fixed plate 31.

The adhesive mat 32 is a plate-like member having adhesive properties. The adhesive mat 32 has a first adhesive surface 32a and a second adhesive surface 32b. The first adhesive surface 32a and the second adhesive surface 32b are surfaces perpendicular to the thickness direction of the adhesive mat 32. The second adhesive surface 32b is a surface located opposite the first adhesive surface 32a in the thickness direction of the adhesive mat 32. The first adhesive surface 32a is attached to the second surface 31b of the fixing plate 31. As a result, the adhesive mat 32 and the fixing plate 31 are integrated as the first fixing part 13.

The first fixed portion 13 has a fixed surface 13a and a non-fixed surface 13b. The fixed surface 13a and the non-fixed surface 13b are surfaces perpendicular to the direction in which the fixed plate 31 and the adhesive mat 32 overlap. The non-fixed surface 13b is a surface located opposite the fixed surface 13a.

As shown in FIG. 2, the fixed surface 13a is a surface that is fixed to the installation surface F. In this embodiment, the fixed surface 13a is the second adhesive surface 32b of the adhesive mat 32. Note that, before the fixed body 10 is used, the second adhesive surface 32b is covered with a protective sheet (not shown). When the fixed body 10 is used, the protective sheet is peeled off, thereby exposing the fixed surface 13a. In this embodiment, the non-fixed surface 13b is the first surface 31a of the fixed plate 31.

The first connecting part 14 is a rectangular plate. In this embodiment, the first connecting part 14 is integrally formed with the fixed plate 31. The first connecting part 14 extends in the plate thickness direction of the fixed plate 31 from one side extending in the longitudinal direction of the fixed plate 31.

The longitudinal direction of the first connecting part 14 coincides with the longitudinal direction of the fixed plate 31. The lateral direction of the first connecting part 14 coincides with the plate thickness direction of the fixed plate 31. The plate thickness direction of the first connecting part 14 coincides with the plate thickness direction of the fixed plate 31. The first base 11 is L-shaped when viewed from the longitudinal direction of the fixed plate 31 and the first connecting part 14.

The first connecting portion 14 has a first surface 14a and a second surface 14b. The first surface 14a and the second surface 14b are surfaces perpendicular to the plate thickness direction of the first connecting portion 14. The second surface 14b is a surface located opposite the first surface 14a in the plate thickness direction of the first connecting portion 14. The first surface 14a is a surface facing in the opposite direction to the direction in which the fixing plate 31 extends from the first connecting portion 14. The second surface 14b is a surface facing in the direction in which the fixing plate 31 extends from the first connecting portion 14.

The first connecting part 14 has a first bolt hole 41. In this embodiment, the first connecting part 14 has three first bolt holes 41. The three first bolt holes 41 are aligned in the longitudinal direction of the first connecting part 14.

Each first bolt hole 41 is a through hole that penetrates the first connecting part 14 in the plate thickness direction. The axial direction of each first bolt hole 41 extends in the plate thickness direction of the first connecting part 14. Each first bolt hole 41 is an elongated hole. The longitudinal direction of each first bolt hole 41 extends in the short direction of the first connecting part 14. The short direction of each first bolt hole 41 extends in the longitudinal direction of the first connecting part 14.

The first connecting part 14 has a slit 42. In this embodiment, the first connecting part 14 has two slits 42. The two slits 42 are lined up in the longitudinal direction of the first connecting part 14. The slits 42 are disposed between the first bolt holes 41 in the longitudinal direction of the first connecting part 14. In other words, the first bolt holes 41 and the slits 42 are lined up alternately in the longitudinal direction of the first connecting part 14.

Each slit 42 is a through hole that penetrates the first connecting part 14 in the plate thickness direction. The axial direction of each slit 42 extends in the plate thickness direction of the first connecting part 14. The axial direction of each slit 42 coincides with the axial direction of each first bolt hole 41. The slit 42 has a first opening 421 that opens in the first surface 14a of the first connecting part 14 and a second opening 422 that opens in the second surface 14b of the first connecting part 14.

Each slit 42 is an elongated hole. The longitudinal direction of each slit 42 extends in the short direction of the first connecting portion 14. The longitudinal direction of each slit 42 coincides with the longitudinal direction of each first bolt hole 41. The short direction of each slit 42 extends in the longitudinal direction of the first connecting portion 14. The short direction of each slit 42 coincides with the short direction of each first bolt hole 41.

As shown in FIG. 5, each slit 42 is defined by two first inner surfaces 42a and two second inner surfaces 42b. Each first inner surface 42a is a surface that runs along the longitudinal direction of the slit 42. The two first inner surfaces 42a face each other in the lateral direction of the slit 42. The second inner surface 42b is a surface that runs along the lateral direction of the slit 42. The two second inner surfaces 42b face each other in the longitudinal direction of the slit 42.

The longitudinal dimension of the slit 42 is defined as P1. The longitudinal dimension P1 of the slit 42 can also be considered as the distance between the two second inner surfaces 42b that define the slit 42. The transverse dimension P2 of the slit 42 can also be considered as the distance between the two first inner surfaces 42a that define the slit 42.

The dimensions P1 and P2 of the slit 42 are constant in the plate thickness direction of the first connecting portion 14. The longitudinal dimension P1 of the slit 42 is approximately the same as the longitudinal dimension of the first bolt hole 41. The transverse dimension P2 of the slit 42 is smaller than the transverse dimension of the first bolt hole 41.

As shown in Figures 3 and 4, the first connecting portion 14 has a pair of retaining pieces 43. The pair of retaining pieces 43 are provided along a pair of short sides of the first connecting portion 14. The pair of retaining pieces 43 are portions where the pair of short sides of the first connecting portion 14 are bent toward the second surface 14b of the first connecting portion 14.

<Second Base>
The second base 12 has a second fixing portion 15 and a second connecting portion 16. The second fixing portion 15 is a portion that is coupled to the installation body S or that presses the installation body S toward the installation surface F. The second fixing portion 15 in this embodiment presses the installation body S toward the installation surface F. The second connecting portion 16 is a portion that is connected to the first connecting portion 14 of the first base 11.

The second fixed portion 15 is a rectangular plate. The second fixed portion 15 has a first opposing surface 15a and a second opposing surface 15b. The first opposing surface 15a and the second opposing surface 15b are surfaces perpendicular to the plate thickness direction of the second fixed portion 15. The second opposing surface 15b is a surface located opposite the first opposing surface 15a in the plate thickness direction of the second fixed portion 15.

As shown in FIG. 2, the first opposing surface 15a faces the upper surface 100a of the shelf board 100 located at the lowest level among the multiple shelf boards 100 that make up the installation body S. The second opposing surface 15b faces the lower surface 100b of the shelf board 100 located above the shelf board 100 located at the lowest level.

As shown in FIG. 3, the second connecting portion 16 is a rectangular plate. In this embodiment, the second connecting portion 16 is integrally formed with the second fixing portion 15. The second connecting portion 16 extends in the plate thickness direction of the second fixing portion 15 from one side extending in the longitudinal direction of the second fixing portion 15.

The longitudinal direction of the second connecting portion 16 coincides with the longitudinal direction of the second fixed portion 15. The lateral direction of the second connecting portion 16 coincides with the plate thickness direction of the second fixed portion 15. The plate thickness direction of the second connecting portion 16 coincides with the lateral direction of the second fixed portion 15. The second base 12 is L-shaped when viewed from the longitudinal direction of the second fixed portion 15 and the second connecting portion 16.

The second connecting portion 16 has a first surface 16a and a second surface 16b. The first surface 16a and the second surface 16b are surfaces perpendicular to the plate thickness direction of the second connecting portion 16. The second surface 16b is a surface located opposite the first surface 16a in the plate thickness direction of the second connecting portion 16. The first surface 16a is a surface facing in the opposite direction to the direction in which the second fixing portion 15 extends from the second connecting portion 16. The second surface 16b is a surface facing in the direction in which the second fixing portion 15 extends from the second connecting portion 16.

The second connecting portion 16 has a second bolt hole 61. In this embodiment, the second connecting portion 16 has three second bolt holes 61. The three second bolt holes 61 are lined up in the longitudinal direction of the second connecting portion 16. The spacing between the second bolt holes 61 in the longitudinal direction of the second connecting portion 16 matches the spacing between the first bolt holes 41 in the longitudinal direction of the first connecting portion 14. The three second bolt holes 61 are located at the end of the second connecting portion 16 opposite the end where the second fixing portion 15 is located in the lateral direction.

Each second bolt hole 61 is a through hole that penetrates the second connecting portion 16 in the plate thickness direction. The axial direction of each second bolt hole 61 extends in the plate thickness direction of the second connecting portion 16. Each second bolt hole 61 is a circular hole. In this embodiment, each second bolt hole 61 is a female threaded hole with a female thread formed on the inner circumferential surface that defines the second bolt hole 61.

The second connecting portion 16 has a protrusion 62. The second connecting portion 16 of this embodiment has two protrusions 62. The two protrusions 62 are aligned in the longitudinal direction of the second connecting portion 16. The protrusions 62 are arranged between the second bolt holes 61 in the longitudinal direction of the second connecting portion 16. The second bolt holes 61 and the protrusions 62 are aligned alternately in the longitudinal direction of the second connecting portion 16. The position of the protrusions 62 in the lateral direction of the second connecting portion 16 coincides with the position of the second bolt hole 61. In other words, the two protrusions 62 are located at the end opposite the end where the second fixing portion 15 is located in the lateral direction of the second connecting portion 16. In the longitudinal direction of the second connecting portion 16, the second bolt holes 61 and the protrusions 62 are aligned in a straight line.

The protrusion 62 protrudes from the first surface 16a of the second connecting part 16 in the plate thickness direction of the second connecting part 16. The shape of the protrusion 62 is a truncated pyramid. When viewed from the plate thickness direction of the first connecting part 14, the protrusion 62 is approximately rectangular. The longitudinal direction of the protrusion 62 extends in the lateral direction of the second connecting part 16. The lateral direction of the protrusion 62 extends in the longitudinal direction of the second connecting part 16.

As shown in FIG. 5, each protrusion 62 has two first outer surfaces 62a and two second outer surfaces 62b. The two first outer surfaces 62a are paired in the short direction of the protrusion 62. The two second outer surfaces 62b are paired in the long direction of the protrusion 62.

The longitudinal dimension of the protrusion 62 is Q1. The longitudinal dimension Q1 of the protrusion 62 can also be said to be the distance between the two second outer surfaces 62b of the protrusion 62. The distance between the two second outer surfaces 62b gradually increases from the tip to the base end of the protrusion 62. Therefore, the dimension Q1 of the protrusion 62 gradually increases from the tip to the base end of the protrusion 62. The longitudinal dimension Q1 of the protrusion 62 is always smaller than the longitudinal dimension P1 of the slit 42.

The dimension Q2 in the short direction of the protrusion 62 is also called the distance between the two first outer surfaces 62a of the protrusion 62. The distance between the two first outer surfaces 62a gradually increases from the tip to the base end of the protrusion 62. Therefore, the dimension Q2 of the protrusion 62 gradually increases from the base end to the tip of the protrusion 62. The dimension Q2 in the short direction of the protrusion 62 is always smaller than the dimension Q1 in the longitudinal direction of the protrusion 62.

As shown in FIG. 6B, the protrusion 62 has a narrow portion 62c and a wide portion 62d. The narrow portion 62c is a portion in which the dimension Q21 of the protrusion 62 in the short side direction is smaller than the dimension P2 of the slit 42 in the short side direction. The wide portion 62d is a portion in which the dimension Q22 of the protrusion 62 in the short side direction is the same as the dimension P2 of the slit 42 in the short side direction, or is larger than the dimension P2 of the slit 42 in the short side direction. Therefore, it can be said that the dimension Q22 of the protrusion 62 in the short side direction at the wide portion 62d is larger than the dimension Q21 of the protrusion 62 in the short side direction at the narrow portion 62c. In the wide portion 62d of this embodiment, the dimension Q22 of the protrusion 62 in the short side direction is the same as the dimension P2 of the slit 42 in the short side direction. The wide portion 62d is provided on the base end side of the narrow portion 62c in the protrusion direction of the protrusion 62 from the second connecting portion 16. In this embodiment, the wide portion 62d is provided at the base end of the protrusion 62.

As shown in Fig. 6(a) and Fig. 7(a), the first base 11 and the second base 12 are integrated by connecting the first connecting portion 14 and the second connecting portion 16 with a fastening member. Note that the first fixing portion 13 is not shown in Fig. 6(a) and Fig. 7(a).

The first connecting portion 14 and the second connecting portion 16 are connected in a stacked state. When the first connecting portion 14 and the second connecting portion 16 are stacked, the plate thickness direction of the first connecting portion 14 and the plate thickness direction of the second connecting portion 16 coincide. The longitudinal direction of the first connecting portion 14 and the longitudinal direction of the second connecting portion 16 coincide. The short side direction of the first connecting portion 14 and the short side direction of the second connecting portion 16 coincide. The direction in which the first connecting portion 14 and the second connecting portion 16 are stacked is referred to as the first direction.

The axial direction of the first bolt hole 41 and the axial direction of the second bolt hole 61 are aligned. The axial directions of the first bolt hole 41 and the second bolt hole 61 extend in a first direction. The longitudinal direction of the first bolt hole 41 and the longitudinal direction of the second bolt hole 61 are aligned. The longitudinal direction of the first bolt hole 41 and the second bolt hole 61 is defined as a second direction. The second direction is perpendicular to the first direction. The second direction is aligned with the short side direction of the first connecting portion 14 and the second connecting portion 16. The short side direction of the first bolt hole 41 and the short side direction of the second bolt hole 61 are aligned. The short side direction of the first bolt hole 41 and the second bolt hole 61 is defined as a third direction. The third direction is perpendicular to both the first direction and the second direction. The third direction is aligned with the longitudinal direction of the first connecting portion 14 and the second connecting portion 16.

The first bolt hole 41 and the second bolt hole 61 are in communication. The shaft B1 of the bolt B is inserted into the first bolt hole 41 and then screwed into the female thread of the second bolt hole 61. This connects the first connecting part 14 and the second connecting part 16. The bolt B and the protrusion 62 are aligned in a straight line in the third direction. The head B2 of the bolt B protrudes from the first surface 14a of the first connecting part 14. A flat washer W1 and a spring washer W2 are interposed between the head B2 of the bolt B and the first surface 14a of the first connecting part 14.

The protrusion 62 is inserted into the slit 42. In other words, the slit 42 is a protrusion insertion portion into which the protrusion 62 is inserted. The first outer surface 62a of the protrusion 62 extends in the second direction. The second outer surface 62b of the protrusion 62 extends in the third direction.

In this embodiment, the first connecting portion 14 and the second connecting portion 16 are overlapped so that the second surface 14b of the first connecting portion 14 and the first surface 16a of the second connecting portion 16 face each other. Therefore, the protrusion 62 is inserted into the slit 42 from the second surface 14b side of the first connecting portion 14. When the protrusion 62 is inserted into the slit 42, the tip of the protrusion 62 passes through the second opening 422 of the slit 42. The second opening 422 is an insertion side opening through which the tip of the protrusion 62 passes when the protrusion 62 is inserted into the slit 42.

As shown in FIG. 4, the first fixing part 13 and the second fixing part 15 extend in the same direction in the first direction from the connected first connecting part 14 and second connecting part 16. The fixing body 10 is C-shaped in a side view. The fixing surface 13a and the non-fixing surface 13b of the first fixing part 13 are surfaces perpendicular to the second direction. The first opposing surface 15a and the second opposing surface 15b of the second fixing part 15 are surfaces perpendicular to the second direction. When the fixing body 10 is not attached to the installation body S, the non-fixing surface 13b of the first fixing part 13 and the first opposing surface 15a of the second fixing part 15 face each other. The second connecting part 16 is located between the pair of holding pieces 43 of the first connecting part 14 in the third direction.

As shown in FIG. 5, the second connecting portion 16 is movable in the second direction relative to the first connecting portion 14. By moving the second connecting portion 16 in the second direction relative to the first connecting portion 14, the distance between the first fixing portion 13 and the second fixing portion 15 in the second direction can be adjusted. When narrowing the distance between the first fixing portion 13 and the second fixing portion 15, the second connecting portion 16 is moved in the second direction relative to the first connecting portion 14 so that the overlapping area between the first connecting portion 14 and the second connecting portion 16 increases. When widening the distance between the first fixing portion 13 and the second fixing portion 15, the second connecting portion 16 is moved in the second direction relative to the first connecting portion 14 so that the overlapping area between the first connecting portion 14 and the second connecting portion 16 decreases.

As described above, the first bolt hole 41 and the slit 42 are elongated holes extending in the second direction. Therefore, the shaft B1 of the bolt B inserted into the first bolt hole 41 can move in the second direction within the first bolt hole 41. Furthermore, the protrusion 62 inserted into the slit 42 can move in the second direction within the slit 42. Therefore, even if the bolt B is not removed to release the connection between the first connecting part 14 and the second connecting part 16, the second connecting part 16 can be moved in the second direction relative to the first connecting part 14 while the first connecting part 14 and the second connecting part 16 remain overlapped.

The connection state between the first connecting portion 14 and the second connecting portion 16 includes a temporary connection state and a full connection state.
6A shows the fixed body 10 when the first connecting portion 14 and the second connecting portion 16 are in a provisionally connected state. The provisionally connected state is a state in which the first connecting portion 14 and the second connecting portion 16 are connected to each other, but the second connecting portion 16 is movable relative to the first connecting portion 14 in the second direction.

Figure 7 (a) shows the fixed body 10 when the first connecting part 14 and the second connecting part 16 are in a fully connected state. This fully connected state is a state in which the first connecting part 14 and the second connecting part 16 are connected, and the second connecting part 16 cannot move relative to the first connecting part 14 in the second direction.

When changing the connection state between the first connecting part 14 and the second connecting part 16 from a provisional connection state to a permanent connection state, the degree of tightening of bolt B is increased. Conversely, when changing the connection state between the first connecting part 14 and the second connecting part 16 from a permanent connection state to a provisional connection state, the degree of tightening of bolt B is decreased. The degree of tightening of bolt B in the permanent connection state is set to be stronger than the degree of tightening of bolt B in the provisional connection state.

In this embodiment, the degree of tightening of bolt B corresponds to the amount of threading of the shank B1 of bolt B into the second bolt hole 61 of the second connecting part 16. The greater the amount of threading of the shank B1 of bolt B into the second bolt hole 61 of the second connecting part 16, the stronger the degree of tightening of bolt B. Therefore, the amount of threading of the shank B1 of bolt B into the second bolt hole 61 of the second connecting part 16 in the actual connection state is greater than the amount of threading of the shank B1 of bolt B into the second bolt hole 61 of the second connecting part 16 in the temporary connection state.

The greater the amount of threading of the shaft B1 of the bolt B into the second bolt hole 61 of the second connecting part 16, the narrower the distance between the first surface 16a of the second connecting part 16 and the head B2 of the bolt B in the first direction. Therefore, the distance between the first surface 16a of the second connecting part 16 and the head B2 of the bolt B in the first direction in the actual connected state is narrower than the distance between the first surface 16a of the second connecting part 16 and the head B2 of the bolt B in the first direction in the temporary connected state.

More specifically, in the provisionally connected state shown in FIG. 6(a), the distance in the first direction between the first surface 16a of the second connecting portion 16 and the head B2 of the bolt B is wide. Therefore, the first connecting portion 14 can move in the first direction between the first surface 16a of the second connecting portion 16 and the head B2 of the bolt B. The first surface 16a of the second connecting portion 16 and the second surface 14b of the first connecting portion 14 are spaced apart in the first direction.

On the other hand, in the main connection state shown in FIG. 7(a), the distance in the first direction between the first surface 16a of the second connecting portion 16 and the head B2 of the bolt B is narrow. Therefore, the first connecting portion 14 is sandwiched between the second connecting portion 16 and the head B2 of the bolt B. The second surface 14b of the first connecting portion 14 and the first surface 16a of the second connecting portion 16 are in contact.

The narrower the distance in the first direction between the second surface 14b of the first connecting portion 14 and the first surface 16a of the second connecting portion 16, the greater the insertion amount of the protrusion 62 into the slit 42. Therefore, the insertion amount of the protrusion 62 into the slit 42 in the fully connected state is greater than the insertion amount of the protrusion 62 into the slit 42 in the provisionally connected state.

In more detail, in the provisionally connected state shown in FIG. 6(b), a portion of the tip side of the protrusion 62 is inserted into the slit 42, but a portion of the base side of the protrusion 62 is not inserted into the slit 42. A portion of the narrow portion 62c of the protrusion 62 is inserted into the slit 42, but a wide portion 62d of the protrusion 62 is not inserted into the slit 42.

On the other hand, in the fully connected state shown in FIG. 7(b), the entire protrusion 62 is inserted into the slit 42. In other words, both the narrow portion 62c and the wide portion 62d of the protrusion 62 are inserted into the slit 42.

As described above, the dimension P2 of the slit 42 in the third direction is constant in the first direction. On the other hand, the dimension Q2 of the protrusion 62 in the third direction increases from the tip to the base. Therefore, the greater the insertion amount of the protrusion 62 into the slit 42, the shorter the shortest distance between the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62. In other words, the two first outer surfaces 62a of the protrusion 62 form a distance shortening portion that shortens the shortest distance between the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62 as the insertion amount of the protrusion 62 into the slit 42 increases. The shortest distance in the actual connection state is shorter than the shortest distance in the temporary connection state.

More specifically, in the provisionally connected state shown in FIG. 6(b), a portion of the narrow portion 62c of the protrusion 62 is inserted into the slit 42. The dimension Q21 of the narrow portion 62c is smaller than the dimension P2 of the slit 42. As a result, a gap is generated between the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62. In this way, in the provisionally connected state, the distance between the first inner surface 42a that defines the slit 42 in the third direction at the narrow portion 62c and the first outer surface 62a of the protrusion 62 is the shortest.

On the other hand, in the fully connected state shown in FIG. 7(b), both the narrow portion 62c and the wide portion 62d of the protrusion 62 are inserted into the slit 42. In the narrow portion 62c, as in the provisionally connected state, a gap is created between the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62. The dimension Q22 of the wide portion 62d is the same as the dimension P2 of the slit 42. Therefore, in the wide portion 62d, the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62 are in contact.

In this manner, in the fully connected state, the distance between the first inner surface 42a that defines the slit 42 in the third direction at the wide portion 62d and the first outer surface 62a of the protrusion 62 is the shortest distance. The shortest distance in the fully connected state is shorter than the shortest distance in the temporary connected state. In this embodiment, the wide portion 62d abuts against the first inner surface 42a that defines the slit 42, so the shortest distance in the fully connected state is zero.

<<How to use the fixed body>>
A method for fixing the installation body S to the installation surface F using the fixing body 10 will be described.
First, the worker sets the connection state between the first connecting portion 14 and the second connecting portion 16 to a provisionally connected state. In other words, the worker sets the second connecting portion 16 to be movable relative to the first connecting portion 14 in the second direction.

The worker then places the fixed body 10 on the installation surface F. The worker places the fixed body 10 so that the first fixing part 13 is located on the lower side and the second fixing part 15 is located on the upper side. The fixing surface 13a of the first fixing part 13 faces the installation surface F via the protective sheet. The first connecting part 14 and the second connecting part 16 extend perpendicular to the installation surface F.

The worker then adjusts the height of the second fixing part 15. The worker adjusts the height of the first opposing surface 15a of the second fixing part 15 to the height of the upper surface 100a of the shelf board 100. The worker adjusts the height of the second fixing part 15 by moving the second connecting part 16 relative to the first connecting part 14 in the second direction. Specifically, if the first opposing surface 15a of the second fixing part 15 is located above the upper surface 100a of the shelf board 100, the worker moves the second connecting part 16 relative to the first connecting part 14 so that the gap between the first fixing part 13 and the second fixing part 15 is narrowed. On the other hand, if the first opposing surface 15a of the second fixing part 15 is located below the upper surface 100a of the shelf board 100, the worker moves the second connecting part 16 relative to the first connecting part 14 so that the gap between the first fixing part 13 and the second fixing part 15 is widened.

The worker then places the fixed body 10 on the installation body S. The worker places the fixed body 10 so that the shelf board 100 located at the bottom is located between the first fixed part 13 and the second fixed part 15.

As shown in FIG. 2, the first fixing portion 13 is disposed between the shelf board 100 located at the lowest level and the installation surface F. The non-fixed surface 13b of the first fixing portion 13 faces the lower surface 100b of the shelf board 100 while being spaced apart. The second fixing portion 15 is disposed between the shelf board 100 located at the lowest level and the shelf board 100 located above the shelf board 100. The first opposing surface 15a of the second fixing portion 15 abuts the upper surface 100a of the shelf board 100. The second opposing surface 15b of the second fixing portion 15 faces the lower surface 100b of the shelf board 100 located above the shelf board 100 to which the fixing body 10 is attached while being spaced apart. The first connecting portion 14 and the second connecting portion 16 are disposed on the sides of the shelf board 100. The second surface 16b of the second connecting portion 16 faces the side surface 100c of the shelf board 100.

The worker then lifts the first base 11 upward to remove the protective sheet covering the second adhesive surface 32b of the adhesive mat 32. That is, the worker moves the first connecting portion 14 in the second direction relative to the second connecting portion 16 so that the gap between the first fixing portion 13 and the second fixing portion 15 narrows. This creates a gap between the installation surface F and the first fixing portion 13. The worker removes the protective sheet covering the second adhesive surface 32b of the adhesive mat 32. The second adhesive surface 32b, which is the fixing surface 13a, is exposed. The worker attaches the fixing surface 13a to the installation surface F. The first fixing portion 13 is fixed to the installation surface F by the adhesive force of the adhesive mat 32. When fixing the fixing surface 13a to the installation surface F, the second surface 16b of the second connecting portion 16 is abutted against the side surface 100c of the shelf board 100.

Finally, the worker tightens the bolt B while pressing the second fixing portion 15 against the top surface 100a of the shelf board 100. At this time, of the three bolts B lined up in the third direction, the worker tightens the bolt B located in the center, and then tightens the bolts B located on both sides. This brings the connection state between the first connecting portion 14 and the second connecting portion 16 into a main connection state. In other words, the second connecting portion 16 cannot move relative to the first connecting portion 14 in the second direction. The second fixing portion 15 presses the top surface 100a of the shelf board 100 toward the installation surface F.

When the four fixed bodies 10 are attached to the installation body S, the first fixed portion 13 of each fixed body 10 is fixed to the installation surface F, and the second fixed portion 15 of each fixed body 10 presses the shelf board 100 toward the installation surface F. As a result, each fixed body 10 restricts the installation body S from moving in a direction away from the installation surface F. In other words, each fixed body 10 restricts the installation body S from floating up from the installation surface F. In addition, the four fixed bodies 10 cooperate with each other to restrict, to a certain extent, the movement of the installation body S in a direction along the installation surface F.

A method for removing the fixed body 10 will now be described.
First, the worker removes the three bolts B. The second fixing portion 15 is left simply placed on the shelf board 100.

The worker then lifts the second base 12 upward to separate the second base 12 from the first base 11. That is, the worker moves the second connecting portion 16 relative to the first connecting portion 14 in the second direction so that the gap between the first fixing portion 13 and the second fixing portion 15 increases. In addition, the first connecting portion 14 and the second connecting portion 16 are moved away from each other in the first direction to position the protrusion 62 outside the slit 42. The worker lifts the first base 11 up to a position where the first connecting portion 14 and the second connecting portion 16 no longer overlap. This separates the second base 12 from the first base 11.

The worker removes the adhesive mat 32 of the first fixed part 13 from the installation surface F, for example, using a scraper. At this time, if the installation body S is moved to a position where the lower surface 100b of the shelf board 100 is no longer opposite the non-fixed surface 13b of the first fixed part 13, the adhesive mat 32 can be removed more easily from the installation surface F. By removing the adhesive mat 32 from the installation surface F, the first base 11 is no longer fixed to the installation surface F, and the removal of the fixed body 10 is completed. The adhesive mat 32 can be reused by washing it.

The operation and effects of this embodiment will be described.
(1) The first connecting portion 14 has a slit 42. The second connecting portion 16 has a protrusion 62 protruding from the second connecting portion 16 in the first direction. The protrusion 62 is inserted into the slit 42. A dimension P2 of the slit 42 in the third direction is constant in the first direction. A dimension Q2 of the protrusion 62 in the third direction increases from the tip to the base end of the protrusion 62. As a result, the greater the insertion amount of the protrusion 62 into the slit 42, the shorter the shortest distance between the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62.

When the second connecting part 16 is moved relative to the first connecting part 14 in the second direction, the degree of tightening of the bolt B is weakened and the first connecting part 14 and the second connecting part 16 are moved away from each other in the first direction. This reduces the insertion amount of the protrusion 62 into the slit 42. When the insertion amount of the protrusion 62 into the slit 42 is reduced, the shortest distance between the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62 becomes longer. The longer the shortest distance between the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62, the less likely the protrusion 62 will come into contact with the first inner surface 42a that defines the slit 42. This allows smooth relative movement of the second connecting part 16 with respect to the first connecting part 14.

When the first connecting part 14 and the second connecting part 16 are connected to the actual connected state, the bolt B is rotated to tighten the bolt B. When the bolt B is tightened, the first connecting part 14 and the second connecting part 16 are brought closer to each other in the first direction. This increases the insertion amount of the protrusion 62 into the slit 42. When the insertion amount of the protrusion 62 into the slit 42 increases, the shortest distance between the first inner surface 42a that defines the slit 42 and the first outer surface 62a of the protrusion 62 in the third direction becomes shorter. The shorter the shortest distance between the first inner surface 42a that defines the slit 42 and the first outer surface 62a of the protrusion 62 in the third direction, the more likely the protrusion 62 will come into contact with the first inner surface 42a that defines the slit 42. Therefore, even if the first connecting part 14 tends to rotate with the rotation of the bolt B when the bolt B is tightened, the protrusion 62 comes into contact with the first inner surface 42a that defines the slit 42, thereby preventing the first connecting part 14 from rotating.

(2) For example, if the shape of the protrusion 62 is a truncated cone, when the first connecting portion 14 tries to rotate, both ends of the protrusion 62 in the third direction come into point contact with the first inner surface 42a that defines the slit 42. The points where the protrusion 62 comes into point contact with the first inner surface 42a are the same points in the second direction. In contrast, the protrusion 62 in this embodiment is a truncated pyramid. That is, the first outer surface 62a of the protrusion 62 extends in the second direction. Therefore, when the first connecting portion 14 tries to rotate, one first outer surface 62a and the other first outer surface 62a of the protrusion 62 come into contact with the first inner surface 42a that defines the slit 42 at multiple different points in the second direction. This increases the effect of suppressing the rotation of the first connecting portion 14.

(3) The protrusion 62 has a wide portion 62d. The dimension Q22 of the wide portion 62d is the same as the dimension P2 of the slit 42. Therefore, when the wide portion 62d is inserted into the slit 42, the first outer surface 62a of the protrusion 62 abuts against the first inner surface 42a that defines the slit 42. In other words, the shortest distance in the third direction between the first inner surface 42a that defines the slit 42 and the first outer surface 62a of the protrusion 62 is zero. Therefore, the rotation angle caused by the co-rotation of the first connecting portion 14 can be made smaller.

(4) The dimension Q1 of the protrusion 62 in the second direction is larger than the dimension Q2 of the protrusion 62 in the third direction. That is, the dimension of the first outer surface 62a of the protrusion 62 in the second direction is larger than the dimension of the protrusion 62 in the third direction. As a result, compared to when the dimension Q1 of the protrusion 62 in the second direction is smaller than the dimension Q2 of the protrusion 62 in the third direction, the first outer surface 62a of the protrusion 62 abuts against the first inner surface 42a that defines the slit 42 at a position farther away in the second direction. In addition, the contact area between the first inner surface 42a that defines the slit 42 and the first outer surface 62a of the protrusion 62 is increased. Therefore, the co-rotation of the first connecting portion 14 can be further suppressed.

(5) The first connecting portion 14 has a first bolt hole 41 and a slit 42. Therefore, it is easier to freely set the shapes of the slit 42 and the protrusion 62 compared to when the first bolt hole 41 also serves as the slit 42. This allows the insertion state of the slit 42 and the protrusion 62 to be more optimal.

(6) The bolt B and the protrusion 62 are aligned in a straight line in the third direction. In other words, the bolt B and the protrusion 62 are provided at the same position in the second direction. This increases the amount of relative movement of the second connecting part 16 in the second direction with respect to the first connecting part 14, compared to a case in which the bolt B and the protrusion 62 are arranged at different positions in the second direction.

(7) The first connecting portion 14 has a plurality of first bolt holes 41 in the third direction. The second connecting portion 16 has a plurality of second bolt holes 61 in the third direction. The first connecting portion 14 and the second connecting portion 16 are connected by a plurality of bolts B. There are a plurality of connection portions between the first connecting portion 14 and the second connecting portion 16 by the bolts B in the third direction.

This increases the connection strength between the first connecting part 14 and the second connecting part 16 compared to when there is only one connection between the first connecting part 14 and the second connecting part 16. Also, the variation in the connection strength between the first connecting part 14 and the second connecting part 16 in the third direction is reduced. This improves the stability of the fixed body 10. As a result, the earthquake resistance of the installation body S is improved.

(8) The first connecting portion 14 has a plurality of slits 42 in the third direction. The second connecting portion 16 has a plurality of protrusions 62 in the third direction. Each protrusion 62 is inserted into the slit 42. This more effectively suppresses the co-rotation of the first connecting portion 14 compared to when the protrusion 62 is inserted into the slit 42 at one point. In addition, the effect of suppressing the co-rotation of the first connecting portion 14 is less varied in the third direction. Furthermore, since the first outer surface 62a of each protrusion 62 abuts against the first inner surface 42a that defines each slit 42 at multiple different points in the second direction, each protrusion 62 mutually restricts the co-rotation of the first connecting portion 14. Thus, the effect of suppressing the co-rotation of the first connecting portion 14 is increased.

(9) The first fixing portion 13 and the second fixing portion 15 extend in the same direction in the first direction. The first fixing portion 13 is disposed between the installation surface F and the shelf board 100, so that the appearance is good when the fixing body 10 is attached to the installation body S.

(10) When the degree of tightening of the bolt B is increased to bring the first connecting part 14 and the second connecting part 16 into a permanently connected state, the rotation of the first connecting part 14 is restricted. This restricts the tilting of the first fixing part 13 that would cause the first fixing part 13 to float up from the installation surface F. This makes it possible to uniformly fix the adhesive mat 32 to the installation surface F. In addition, this prevents the first fixing part 13 from being insufficiently fixed to the installation surface F due to the adhesive mat 32 being pulled in a direction that causes it to peel off from the installation surface F due to the tilting of the first fixing part 13.

This embodiment can be modified as follows: The embodiment and the modified examples can be combined with each other to the extent that there is no technical contradiction.
The number of fixing bodies 10 used to fix the installation body S to the installation surface F may be changed as appropriate.

○ The manner in which the fixed bodies 10 are attached to the installation body S is not limited to the manner shown in FIG. 1. The fixed bodies 10 may be attached to the installation body S, for example, as follows. Of the four fixed bodies 10, two fixed bodies 10 are arranged at one end of the shelf board 100 in the short side direction so as to sandwich the shelf board 100 in the longitudinal direction. Of the four fixed bodies 10, the other two fixed bodies 10 are arranged at the other end of the shelf board 100 in the short side direction so as to sandwich the shelf board 100 in the longitudinal direction.

Even when the fixed bodies 10 are attached in this manner, each fixed body 10 can restrict movement of the installation body S in a direction away from the installation surface F. Furthermore, the four fixed bodies 10 can cooperate with each other to restrict, to a certain extent, movement of the installation body S in a direction along the installation surface F.

The first connecting portion 14 may have a protrusion that protrudes in the first direction, and the second connecting portion 16 may have a protrusion insertion portion into which the protrusion is inserted.
The fixing plate 31 of the first fixing part 13 and the first connecting part 14 do not have to be integrally formed. For example, the first base 11 may be configured by connecting the fixing plate 31 of the first fixing part 13 and the first connecting part 14 with each other by a bolt.

The second fixing portion 15 and the second connecting portion 16 do not have to be integrally formed. For example, the second base 12 may be constructed by connecting the second fixing portion 15 and the second connecting portion 16 with a bolt.

The method of fixing the first fixing part 13 to the installation surface F is not limited to adhesion using the adhesive mat 32. As an example, the first fixing part 13 may be fixed to the installation surface F by a bolt. In this case, the adhesive mat 32 can be omitted. In other words, the first fixing part 13 is composed of only the fixing plate 31.

The second fixing part 15 may be connected to the installation body S. The method of connecting the second fixing part 15 to the installation body S may be, for example, connection with a bolt, or attachment using the adhesive force of an adhesive mat. In this case, the second fixing part 15 can not only restrict movement of the installation body S in a direction away from the installation surface F, but also restrict movement of the installation body S in a direction along the installation surface F.

When the second fixing part 15 is attached and fixed to the installation body S by using the adhesive force of the adhesive mat, the second fixing part 15 is composed of a fixing plate and an adhesive mat, like the first fixing part 13 in the above embodiment.

When the second fixing portion 15 is connected to the installation body S by a bolt or an adhesive mat, the task of separating the second base 12 from the first base 11 when removing the fixing body 10 may be performed with the second fixing portion 15 connected to the installation body S. In other words, the first base 11 and the second base 12 can be separated by completely removing the bolt B. The separated second base 12 remains connected to the installation body S.

The second fixing portion 15 may be connected to the underside 100b of the shelf board 100. The second fixing portion 15 may be connected to the installation body S by means of an adhesive mat or bolts.

The second base 12 may be flat. In this case, the second fixing portion 15 is connected to the side surface 100c of the shelf board 100 or the support 101. The second fixing portion 15 is connected to the installation body S by means of an adhesive mat or bolts.

The flat washer W1 and the spring washer W2 may be omitted.
The first connecting portion 14 and the second connecting portion 16 may be connected by screwing a bolt B inserted through the first bolt hole 41 and the second bolt hole 61 into a nut. In other words, the fastening members for connecting the first connecting portion 14 and the second connecting portion 16 may be the bolt B and the nut. In this case, the female thread on the inner circumferential surface defining the second bolt hole 61 is not necessary.

When the bolt B is rotated while the nut is fixed to screw the bolt B and the nut together, the connecting part that abuts against the head B2 of the bolt B tends to rotate along with the nut. On the other hand, when the bolt B is rotated while the nut is fixed to screw the bolt B and the nut together, the connecting part that abuts against the nut tends to rotate along with the nut.

When the first connecting portion 14 and the second connecting portion 16 are connected by a bolt B and a nut, the order in which the shaft portion B1 of the bolt B is inserted into the first bolt hole 41 and the second bolt hole 61 may be changed as appropriate. That is, the shaft portion B1 of the bolt B may be passed through the first bolt hole 41 and then through the second bolt hole 61, or through the second bolt hole 61 and then through the first bolt hole 41.

The number of first bolt holes 41 formed in the first connecting portion 14 may be changed as appropriate. In addition, the number of second bolt holes 61 formed in the second connecting portion 16 may be changed as appropriate according to the number of first bolt holes 41.

The number of slits 42 formed in the first connecting portion 14 may be changed as appropriate. The number of protrusions 62 formed in the second connecting portion 16 may be changed as appropriate depending on the number of slits 42 and the manner in which the protrusions 62 are inserted into the slits 42.

The second bolt hole 61 does not have to be a through hole. The second bolt hole 61 may be a female threaded hole formed in at least one of the first surface 16a and the second surface 16b of the second connecting portion 16.

○ The first bolt hole 41 may be a circular hole, and the second bolt hole 61 may be an elongated hole. A female thread is formed on the inner peripheral surface that defines the first bolt hole 41. A female thread is not formed on the inner peripheral surface that defines the second bolt hole 61. In this case, the shaft portion B1 of the bolt B is inserted into the second bolt hole 61 and then screwed into the first bolt hole 41. The head portion B2 of the bolt B protrudes from the second surface 16b of the second connecting portion 16. Note that the first bolt hole 41 in this example may be a through hole that penetrates the first connecting portion 14 in the plate thickness direction, or may be a female threaded hole formed in at least one of the first surface 14a and the second surface 14b of the first connecting portion 14.

Both the first bolt hole 41 and the second bolt hole 61 may be elongated holes. In this case, the first connecting portion 14 and the second connecting portion 16 are connected to each other by a bolt B and a nut.
The protrusion insertion portion is not limited to a through hole and may be a recess that is recessed from the second surface 14b of the first connecting portion 14 toward the first surface 14a.

○ The short-side dimension P2 of the slit 42 does not have to be constant in the first direction. In this case, it is preferable that the dimensions of the protrusion 62 are set as follows: The dimension of the base end of the protrusion 62 in the third direction is the same as or larger than the dimension of the insertion-side opening in the third direction. The dimension of the tip side of the protrusion 62 in the third direction is smaller than the dimension of the insertion-side opening in the third direction.

As long as the dimension Q2 of the protrusion 62 is larger on the base end side than on the tip end side of the protrusion 62, the dimension Q2 of the protrusion 62 may change, for example, in a step-like manner.
○ If the dimension Q2 of the protrusion 62 is larger on the base end side than on the tip end side of the protrusion 62, the dimension of the base end side of the protrusion 62 in the third direction may be smaller than the dimension P2 of the slit 42. In this case, even if the entire protrusion 62 is inserted into the slit 42, the first outer surface 62a of the protrusion 62 does not abut against the first inner surface 42a that defines the slit 42. In other words, the shortest distance between the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62 does not become zero. However, the more the protrusion 62 is inserted into the slit 42, the shorter the shortest distance between the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62. Therefore, when the first connecting portion 14 tries to rotate together, the protrusion 62 is likely to come into contact with the first inner surface 42a that defines the slit 42. Therefore, the rotation angle due to the rotation of the first connecting portion 14 can be reduced. Furthermore, even if the first connecting part 14 rotates, it is preferable to set the rotation angle due to the rotation of the first connecting part 14 so that the first outer surface 62a of the protrusion 62 abuts against the first inner surface 42a that defines the slit 42, within a range that does not apply a force to peel the adhesive mat 32 off from the installation surface F.

As shown in Figures 8 and 9, the wide portion 62d may have a portion where the dimension Q22 in the third direction is greater than the dimension P2 of the slit 42, in addition to a portion where the dimension Q22 in the third direction is the same as the dimension P2 of the slit 42. The wide portion 62d is provided at the base end of the protrusion 62. The dimension Q22 of the wide portion 62d gradually increases from the narrow portion 62c toward the base end of the protrusion 62. The dimension of the base end of the protrusion 62 in the third direction is greater than the dimension P2 of the slit 42.

For example, in FIG. 8, the dimension Q22 of the wide portion 62d increases in a curved manner from the narrow portion 62c toward the base end of the projection 62.
For example, in FIG. 9, the dimension Q22 of the wide portion 62d increases linearly from the narrow portion 62c toward the base end of the projection 62.

In this case, the portion of the wide portion 62d where the dimension Q22 in the third direction is the same as the dimension P2 of the slit 42 is inserted into the slit 42, but the portion where the dimension Q22 in the third direction is greater than the dimension P2 of the slit 42 is not inserted into the slit 42. In other words, the wide portion 62d is not completely inserted into the slit 42. In this configuration, in this connected state, the second surface 14b of the first connecting portion 14 and the first surface 16a of the second connecting portion 16 are not in contact with each other.

The wide portion 62d may be fully inserted into the slit 42 by tightening the bolt B. The portion of the wide portion 62d whose dimension Q22 in the third direction is greater than the dimension P2 of the slit 42 is pressed into the slit 42. In this case, co-rotation of the first connecting portion 14 can be more effectively suppressed compared to when the protrusion 62 simply abuts against the first inner surface 42a that defines the slit 42.

The wide portion 62d is provided at the base end of the protrusion 62. Therefore, for example, the amount of rotation of the bolt B when inserting the wide portion 62d into the slit 42 can be reduced compared to when the wide portion 62d is provided in the base half of the protrusion 62. Note that the wide portion 62d is preferably provided at the base end of the protrusion 62 in a range that is inserted into the slit 42 when the bolt B is rotated once.

Furthermore, the dimension Q22 of the wide portion 62d gradually increases from the narrow portion 62c toward the base end of the protrusion 62. Therefore, even if there is an error in the dimension P2 of the slit 42 or the dimension Q2 of the protrusion 62, the protrusion 62 can be abutted against the first inner surface 42a that defines the slit 42.

The fixed body 10 may have the following configuration.
As shown in Fig. 10, the first connecting portion 14 has three first bolt holes 41. The second connecting portion 16 has three second bolt holes 61 and six protrusions 62. The protrusions 62 are arranged two by two at positions corresponding to the second bolt holes 61 in the third direction. The two protrusions 62 are arranged on both sides of the second bolt hole 61 in the second direction. The two protrusions 62 are adjacent to the second bolt hole 61 located between the two protrusions 62 in the second direction.

As shown in FIG. 11, the bolt B is inserted through the first bolt hole 41 and screwed into the second bolt hole 61, as in the above embodiment. The protrusion 62 is inserted into the first bolt hole 41. The first bolt hole 41 also serves as the slit 42 in the above embodiment, i.e., the protrusion insertion portion. The two protrusions 62 located on either side of the second bolt hole 61 in the second direction are inserted into one first bolt hole 41 that communicates with the second bolt hole 61. In other words, multiple protrusions 62 are inserted into one protrusion insertion portion.

In this case, the number of holes formed in the first connecting portion 14 is smaller than in the above embodiment. Therefore, the strength of the first connecting portion 14 is higher than in the above embodiment. This improves the stability of the fixed body 10. As a result, the earthquake resistance of the installation body S is improved. However, the range of relative movement of the second connecting portion 16 in the second direction with respect to the first connecting portion 14 is narrower than in the above embodiment.

The protrusion 62 is also provided adjacent to the second bolt hole 61. This makes it possible to better suppress co-rotation of the first connecting part 14 compared to when the protrusion 62 is provided at a position away from the second bolt hole 61.

When multiple protrusions 62 are arranged in the second direction, the first outer surface 62a of each protrusion 62 does not necessarily have to extend in the second direction. Specifically, the shape of each protrusion 62 may be, for example, a truncated cone or a cone. The diameter of each protrusion 62 increases from the tip to the base end of the protrusion 62. If the first outer surface 62a of one or more of the multiple protrusions 62 extends in the second direction, co-rotation of the first connecting portion 14 can be further suppressed.

When multiple protrusions 62 are provided in the second direction, the contact area between the first inner surface 42a that defines the slit 42 and the first outer surface 62a of the protrusion 62 can be increased compared to when only one protrusion 62 is provided in the second direction. Furthermore, when the first connecting portion 14 attempts to rotate, each protrusion 62 abuts against the first inner surface 42a that defines the slit 42 at multiple different points in the second direction. This increases the effect of suppressing the rotation of the first connecting portion 14.

The fixed body 10 may have the following configuration.
12, the first connecting portion 14 has two first bolt holes 41. The second connecting portion 16 has two second bolt holes 61 and two protrusions 62. The two protrusions 62 are located on both sides of the two second bolt holes 61 in the third direction. Each protrusion 62 is adjacent to a corresponding second bolt hole 61 in the third direction.

As shown in FIG. 13, the second bolt hole 61 communicates with the first bolt hole 41. A bolt B (not shown) is inserted through the first bolt hole 41 and screwed into the second bolt hole 61. Each protrusion 62 is inserted into each first bolt hole 41. The first bolt hole 41 also serves as the slit 42 in the above embodiment, i.e., the protrusion insertion portion.

In this case, the number of holes formed in the first connecting portion 14 is smaller than in the above embodiment. Therefore, the strength of the first connecting portion 14 is higher than in the above embodiment. This improves the stability of the fixed body 10. As a result, the earthquake resistance of the installation body S is improved.

The protrusion 62 is also provided adjacent to the second bolt hole 61. This makes it possible to better suppress co-rotation of the first connecting part 14 compared to when the protrusion 62 is provided at a position away from the second bolt hole 61.

As shown in FIG. 14, the first connecting portion 14 and the second connecting portion 16 may be overlapped so that the first surface 14a of the first connecting portion 14 and the first surface 16a of the second connecting portion 16 face each other. The first fixing portion 13 faces one side of the first direction. The second fixing portion 15 faces the other side of the first direction. In other words, the extension direction of the first fixing portion 13 from the first connecting portion 14 and the second connecting portion 16 is opposite to the extension direction of the second fixing portion 15 from the first connecting portion 14 and the second connecting portion 16. The protrusion 62 is inserted into the slit 42 from the first surface 14a side of the first connecting portion 14. When the protrusion 62 is inserted into the slit 42, the tip of the protrusion 62 passes through the first opening 421 of the slit 42. Therefore, the first opening 421 is an insertion side opening through which the tip of the protrusion 62 passes when the protrusion 62 is inserted into the slit 42.

In this case, since the first fixing portion 13 is not located between the shelf board 100 and the installation surface F, the workability is improved when fixing the first fixing portion 13 to the installation surface F and removing the first fixing portion 13 from the installation surface F.

In addition, the slit 42 may not be a through hole, but may be a recess that is recessed from the first surface 14a toward the second surface 14b of the first connecting part 14. Also, if recesses are formed on both the first surface 14a and the second surface 14b of the first connecting part 14, it is possible to select the surface to be opposed when the second connecting part 16 is superimposed on the first connecting part 14, just as in the case where the slit 42 is a through hole.

The shapes of the slits 42 and the protrusions 62 may be changed, for example, as follows.
15 and 16, the protrusion 62 has a substantially cylindrical shape. The dimension of the protrusion 62 in the third direction is defined as X. The dimension X of the protrusion 62 is constant in the first direction.

The dimension of the slit 42 in the third direction is defined as Y. The dimension Y of the slit 42 in the third direction can also be said to be the distance between the two first inner surfaces 42a of the slit 42. The distance between the two first inner surfaces 42a becomes shorter from the second surface 14b toward the first surface 14a of the first connecting portion 14. Therefore, the dimension Y of the slit 42 becomes smaller from the second surface 14b toward the first surface 14a of the first connecting portion 14.

The slit 42 has a narrow portion 42c and a wide portion 42d. The narrow portion 42c is a portion where the dimension Y1 of the slit 42 in the third direction is smaller than the dimension X of the protrusion 62. The wide portion 42d is a portion where the dimension Y2 of the slit 42 in the third direction is the same as or larger than the dimension X of the protrusion 62. The narrow portion 42c is located on the first surface 14a side of the first connecting portion 14. The wide portion 42d is located on the second surface 14b side of the first connecting portion 14.

The protrusion 62 is inserted into the slit 42 from the second surface 14 b of the first connecting portion 14 .
In this case, the dimension X of the protrusion 62 is constant, while the dimension Y of the slit 42 decreases from the second surface 14b to the first surface 14a of the first connecting portion 14. Therefore, the greater the insertion amount of the protrusion 62 into the slit 42, the shorter the shortest distance between the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62. The two first inner surfaces 42a of the slit 42 form a distance shortening portion that shortens the shortest distance between the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62 as the insertion amount of the protrusion 62 into the slit 42 increases. With this configuration, the same effect as effect (1) of the above embodiment can be obtained.

In other words, the shapes of the slit 42 and the protrusion 62 may be changed as appropriate, provided that the greater the insertion amount of the protrusion 62 into the slit 42, the shorter the shortest distance between the first inner surface 42a that defines the slit 42 in the third direction and the first outer surface 62a of the protrusion 62.
