Description

The present invention relates to an assembly support and an assembly.

An assembly-type storage unit formed by assembling a mounting section and a support section is known (for example, Patent Document 1).

JP 2016-52457 A

In the assembly storage unit described in Patent Document 1, the length of the support columns, i.e., the vertical spacing between the mounting sections, can be changed by changing the number of support column members connected to the support column engagement sections. It would be convenient if the length of the support columns could be changed in a way other than by changing the number of support column members. Furthermore, when the support columns are made up of multiple members, it is desirable that the members do not shift or rattle relative to each other.

The object of the present invention is to provide an assembly support and assembly that are adjustable in length and highly stable.

The above problems are solved by the present invention. That is, the present invention (1) provides:
a first support member extending longitudinally from the distal end to the proximal end and having an L-shaped cross section;
a second strut member extending longitudinally from its distal end to its proximal end, having an L-shaped cross-sectional shape and having an outer surface that generally matches the L-shaped inner surface of the first strut member;
Equipped with
a plurality of first engagement portions are provided at predetermined intervals in the longitudinal direction on an inner surface of the L-shaped corner of the first support member;
The second support member has a plurality of second engagement portions that are engageable with the first engagement portions and are provided at predetermined intervals in the longitudinal direction on the outer surface of the L-shaped corner of the second support member.

The present invention (2) relates to the assembly support column described in (1), in which the first engagement portion has a first extension portion extending from the inner surface and a second extension portion extending from the first extension portion in a direction different from that of the first extension portion, and the second engagement portion has a third extension portion extending from the outer surface and a fourth extension portion extending from the third extension portion in a direction different from that of the first extension portion, and the first engagement portion and the second engagement portion have shapes that generally fit together.

The assembly support column according to an embodiment of the present invention will now be described with reference to the drawings. The assembly support column according to this embodiment is made up of two support members with an L-shaped cross section. The two support members have multiple engagement portions at the corners of the L-shape, and the length of the support member can be changed by changing the engagement points. The engagement portions at the corners make it difficult for the two support members to shift or rattle.

Figures 1 to 3 are perspective views showing an example of a rack 2, which is an assembly including an assembly support 1 according to an embodiment of the present invention. The rack 2 has a mounting section 10, a caster section 30, and an assembly support 1 (hereinafter also simply referred to as support 1).

The mounting section 10 is a tray on which an item can be placed. The mounting section 10 is made of, for example, resin. In this embodiment, the mounting section 10 has a first mounting section 11 and a second mounting section 12. Because the first mounting section 11 and the second mounting section 12 have the same configuration, only the configuration of the first mounting section 11 will be described here, and a description of the configuration of the second mounting section 12 will be omitted.

The first mounting section 11 has a rectangular storage section 16 on its front side 13, which is composed of a bottom wall 14 and peripheral walls 15. Upper openings 17 are provided at each of the four corners of the storage section 16, to which a support pole 1 can be connected. The upper openings 17 have a shape that roughly matches the tip and base ends of the support pole 1. Lower openings 19 are provided at each of the four corners of the back side 18 of the first mounting section 11, to which a support pole 1 can be connected. The lower openings 19 have a shape that roughly matches the tip and base ends of the support pole 1. Furthermore, on the back side of the first mounting section 11, adjacent to the lower openings 19, are provided mounting sections 21 to which caster sections 30 can be attached. The mounting sections 21 have a shape that roughly matches the shafts of the caster sections 30.

In this embodiment, as shown in Figures 4 and 5, the tip of the support 1 is connected to the lower opening 19 of the first mounting section 11. Furthermore, as shown in Figures 6 and 7, the base end of the support 1 is connected to the upper opening 22 of the second mounting section 12. Furthermore, as shown in Figure 3, the shaft of the caster unit 30 is connected to the mounting section 21 of the second mounting section 12. The support 1 can also be turned upside down. That is, the base end of the support 1 can be connected to the lower opening 19 of the first mounting section 11, and the tip of the support 1 can be connected to the upper opening 22 of the second mounting section 12.

The support 1 is composed of a first support member 31 and a second support member 32. The first support member 31 and the second support member 32 extend longitudinally from the tip to the base end. The support 1 is made of, for example, resin.

Figures 8 to 15 show an example of a first support member 31. The first support member 31 is composed of a mounting connection portion 33 and a support body 34.

The mounting connection portion 33 is the portion at the tip end of the first support member 31. The mounting connection portion 33 has a corner portion 35 and an L-shaped cross-section. The mounting connection portion 33 has an L-shaped inner surface 36 and an L-shaped outer surface 37. The mounting connection portion 33 has a shape that approximately fits the upper openings 17, 22 and lower opening 19 of the mounting portion 10. The tip of the mounting connection portion 33 can be connected to the upper openings 17, 22 or lower opening 19 of the mounting portion 10.

The support body 34 is formed on the base end side of the mounting connection portion 33. The support body 34 has a corner portion 38 and an L-shaped cross-section. The support body 34 has an L-shaped inner surface 39 and an L-shaped outer surface 41. The mounting connection portion 33 and the support body 34 are formed integrally, so that the L-shaped inner surface 39 of the support body 34 is aligned with the L-shaped outer surface 37 of the mounting connection portion 33. The longitudinal axis of the corner portion 35 of the mounting connection portion 33 and the longitudinal axis of the corner portion 38 of the support body 34 are approximately parallel.

A plurality of first engagement portions 43 are provided on the inner corner surface 42 of the support body 34. The first engagement portions 43 are provided at predetermined intervals in the longitudinal direction. The first engagement portions 43 are, for example, protrusions 44. In this embodiment, six protrusions 44, namely, a first protrusion 45, a second protrusion 46, a third protrusion 47, a fourth protrusion 48, a fifth protrusion 49, and a sixth protrusion 51, are arranged at predetermined intervals in the longitudinal direction from the tip end to the base end. A plurality of openings 53 are formed in the outer corner surface 52 of the support body 34. The openings 53 are cutouts created by the provision of the first engagement portions 43.

The first engagement portion 43 has a first extension portion 54 extending from the L-shaped inner surface 39 (corner inner surface 42) of the support body 34, and a second extension portion 55 extending in a different direction from the first extension portion 54. In this embodiment, the first extension portion 54 is a first horizontal extension portion 56 extending approximately horizontally from the L-shaped inner surface 39 (corner inner surface 42) of the support body 34, and the second extension portion 55 is a first vertical extension portion 57 extending approximately vertically from the first horizontal extension portion 56.

The second extension portion 55 (first vertical extension portion 57) is provided with a protrusion portion 58. The protrusion portion 58 is provided, for example, in a direction toward the L-shaped outer surface 41 of the support body 34.

At least one restricting portion 59 is provided on the inner corner surface 42 of the support body 34. For example, a protrusion 61 is provided as the restricting portion 59 closer to the base end than the first engagement portion 43 (sixth protrusion 51) at the bottom of the first support member 31.

Figures 16 to 22 show an example of the second support member 32. The second support member 32 has a corner portion 62 and an L-shaped cross-sectional shape. The second support member 32 has an L-shaped inner surface 63 and an L-shaped outer surface 64. The L-shaped outer surface 64 of the second support member 32 has a shape that approximately matches the L-shaped inner surface 39 of the support body 34 of the first support member 31. The second support member 32 also has a shape that approximately matches the upper openings 17, 22 and lower opening 19 of the mounting portion 10. The base end of the second support member 32 can be connected to the upper openings 17, 22 or lower opening 19 of the mounting portion 10.

The corner outer surface 65 of the second support member 32 is provided with a plurality of second engagement portions 66 that can engage with the first engagement portions 43 of the first support member 31. The second engagement portions 66 are provided at predetermined intervals in the longitudinal direction. The second engagement portions 66 are, for example, openings 67, and in this embodiment, six openings 67, namely, a first opening 68, a second opening 69, a third opening 71, a fourth opening 72, a fifth opening 73, and a sixth opening 74, are arranged at predetermined intervals in the longitudinal direction from the distal end to the proximal end. The spacing between the second engagement portions 66 corresponds to the spacing between the first engagement portions 43.

The second engagement portion 66 has a third extension portion 75 extending from the L-shaped outer surface 64 (corner outer surface 65) of the second support member 32, and a fourth extension portion 76 extending from the third extension portion 75 in a direction different from that of the third extension portion 75. In this embodiment, the third extension portion 75 is a second horizontal extension portion 77 extending approximately horizontally from the outer surface 64 (corner outer surface 65) of the second support member 32, and the fourth extension portion 76 is a second vertical extension portion 78 extending approximately vertically from the second horizontal extension portion 77. The first engagement portion 43 and the second engagement portion 66 have shapes that approximately fit together.

The fourth extension portion 76 (second vertical extension portion 78) is provided with a groove portion 79 that fits into the protrusion portion 58 of the second extension portion 55 (first vertical extension portion 57) of the first support member 31. The groove portion 79 is provided, for example, in a direction toward the L-shaped inner surface 63 of the second support member 32. Alternatively, a groove may be provided in the second extension portion 55 (first vertical extension portion 57), and a protrusion that fits into the groove may be provided in the fourth extension portion 76 (second vertical extension portion 78).

The corner outer surface 65 of the second support member 32 is provided with multiple restriction receiving portions 81 that receive the restriction portions 59 of the first support member 31. For example, recesses 82 are provided as restriction receiving portions 81 from the base end to the center of the second support member 32. In this embodiment, four recesses 82, namely a first recess 83, a second recess 84, a third recess 85, and a fourth recess 86, are provided as restriction receiving portions 81 from the base end to the center. The four recesses 82 are arranged at a predetermined interval in the longitudinal direction. Alternatively, multiple recesses may be provided as restriction receiving portions 81 on the corner inner surface 42 of the support body 34 of the first support member 31, and at least one protrusion may be provided as restriction portion 59 on the corner outer surface 65 of the second support member 32 that fits into the recess. Alternatively, recesses may be provided as restriction receiving portions 81 from the tip end to the center of the first support member 31, and a protrusion may be provided as restriction portion 59 on the tip end of the second support member 32.

The following describes how to assemble the first support member 31 and the second support member 32, and how to change the length of the assembly support member 1. The length of the assembly support member 1 can be changed by changing the engagement points of the multiple first and second engagement portions.

Figures 23 to 28 show the state (first state) in which the first support member 31 and the second support member 32 are assembled to make the support member 1 as short as possible. Note that the support member 1 of the rack 2 shown in Figure 1 is also in the first state.

In the first state, the six protrusions 44 of the first engagement portion 43 are respectively engaged with the six openings 67 of the second engagement portion 66. That is, the first protrusion 45 engages with the first opening 68, the second protrusion 46 engages with the second opening 69, the third protrusion 47 engages with the third opening 71, the fourth protrusion 48 engages with the fourth opening 72, the fifth protrusion 49 engages with the fifth opening 73, and the sixth protrusion 51 engages with the sixth opening 74. In the first state, the entire L-shaped inner surface 39 of the support body 34 of the first support member 31 abuts against the L-shaped outer surface 64 of the second support member 32. Additionally, as shown in FIG. 28, the protrusions 58 of the second extensions 55 (first vertical extensions 57) of the first engagement portion 43 fit into the grooves 79 of the fourth extensions 76 (second vertical extensions 78) of the second engagement portion 66.

When assembling the first support member 31 and the second support member 32, the first engagement portion 43 is pushed horizontally toward the second engagement portion 66 and then pushed vertically. Pushing it horizontally engages the first extension portion 54 (first horizontal extension portion 56) and the third extension portion 75 (second horizontal extension portion 77). Pushing it vertically engages the protrusion portion 58 into the groove portion 79, and engages the second extension portion 55 (first vertical extension portion 57) and the fourth extension portion 76 (second vertical extension portion 78). In other words, engagement between the first engagement portion 43 and the second engagement portion engages the first horizontal extension portion 56 and the second horizontal extension portion 77, engages the first vertical extension portion 57 and the second vertical extension portion 78, and engages the protrusion portion 58 and the groove portion 79.

In addition, in the first state, as shown in FIG. 27, the convex portion 61, which is the restricting portion 59 of the first support member 31, engages with the first concave portion 83, which is the restricting portion closest to the base end of the four restricting portions 81 of the second support member 32.

Figures 29 to 34 show the state (second state) in which the first support member 31 and the second support member 32 are assembled to make the support member 1 as long as possible. Note that the support member 1 of the rack 2 shown in Figures 2 to 4 and 6 is also in the second state.

In the second state, three of the six protrusions 44 of the first engagement portion 43, located closest to the base end, are engaged with three of the six openings 67 of the second engagement portion 66, located closest to the tip end. That is, the fourth protrusion 48 is engaged with the first opening 68, the fifth protrusion 49 is engaged with the second opening 69, and the sixth protrusion 51 is engaged with the third opening 71. In the second state, a portion of the L-shaped inner surface 39 of the support body 34 of the first support member 31 abuts against the L-shaped outer surface 64 of the second support member 32. In the second state, as shown in FIG. 28 , the protrusions 58 of the second extension portions 55 (first vertical extension portions 57) of the first engagement portion 43 are fitted into the grooves 79 of the fourth extension portions 76 (second vertical extension portions 78) of the second engagement portion 66.

In addition, in the second state, as shown in Figure 34, the convex portion 61, which is the restricting portion 59 of the first support member 31, engages with the fourth concave portion 86, which is the restricting portion closest to the tip of the four restricting portions 81 of the second support member 32.

The strut 1 can be set to a length between the first state and the second state. That is, the strut 1 can be in a state in which five of the six protrusions 44 constituting the first engagement portion 43 (the second protrusion 46, the third protrusion 47, the fourth protrusion 48, the fifth protrusion 49, and the sixth protrusion 51) from the base end engage with five of the six openings 67 constituting the second engagement portion 66 (the first opening 68, the second opening 69, the third opening 71, the fourth opening 72, and the fifth opening 73) from the tip end, respectively; or in which four of the protrusions (the third protrusion 47, the fourth protrusion 48, the fifth protrusion 49, and the sixth protrusion 51) from the base end engage with four openings (the first opening 68, the second opening 69, the third opening 71, and the fourth opening 72) from the tip end, respectively. When the five protruding portions from the base end engage with the five openings from the tip end, respectively, the convex portion 61, which is the restricting portion 59 of the first support member 31, engages with the second recessed portion 84, which is the second restricting portion from the base end, of the four restricting portions 81 of the second support member 32. Furthermore, when the four protruding portions from the base end engage with the four openings from the tip end, respectively, the convex portion 61, which is the restricting portion 59 of the first support member 31, engages with the third recessed portion 85, which is the third restricting portion from the base end, of the four restricting portions of the second support member 32.

In the second state, the three first engagement portions 43 (fourth protrusion 48, fifth protrusion 49, and sixth protrusion 51) from the base end side of the first support member 31 are engaged with the three second engagement portions 66 (first opening 68, second opening 69, and third opening 71) from the tip end side of the second support member 32. Also, in the second state, as shown in FIG. 34 , the convex portion 61, which is the regulating portion 59 of the first support member 31, is engaged with the fourth recess 86, which is the central regulating receiving portion of the four regulating receiving portions 81 of the second support member 32 and is the farthest from the base end side. Even if the strut 1 is made longer than in the second state, the second strut member 32 does not have a restricting portion distal to the fourth recess 86. This causes the restricting portion 59 of the first strut member 31 to abut against the outer corner surface 65 of the second strut member 32, preventing the first strut member 31 and the second strut member 32 from being assembled. When the first strut member 31 and the second strut member 32 are assembled, the first engaging portions 43 and the second engaging portions 66 are engaged at at least three locations. From the perspective of strut strength and stability, it is preferable that multiple first engaging portions 43 and multiple second engaging portions 66 are engaged when the first strut member 31 and the second strut member 32 are assembled.

According to this embodiment, the assembly support 1 comprises a first support member 31 extending longitudinally from its distal end to its proximal end and having an L-shaped cross-section, and a second support member 32 extending longitudinally from its distal end to its proximal end, having an L-shaped cross-section and an outer surface that generally matches the inner L-shape of the first support member 31. A plurality of first engagement portions 43 are provided at predetermined intervals along the length on the inner L-shaped corner surface 42 of the first support member 31, and a plurality of second engagement portions 66 engageable with the first engagement portions 43 are provided at predetermined intervals along the length on the outer L-shaped corner surface 65 of the second support member 32. Because the first engagement portions 43 and the second engagement portions 66 are provided at the corners, respectively, and the first support member 31 and the second support member 32 engage at the corners, the assembly support is resistant to slippage and rattle and has excellent stability. Furthermore, because multiple first engagement portions 43 and second engagement portions 66 are provided at predetermined intervals along the length, it is possible to provide an assembly support 1 whose length can be changed by changing the engagement points of the first engagement portions 43 and second engagement portions 66. Since the length of the support can be easily changed without the use of tools, it is easy to handle and highly convenient.

The first engagement portion 43 has a first extension portion 54 extending from the inner corner surface 42 and a second extension portion 55 extending from the first extension portion 54 in a direction different from that of the first extension portion 54. The second engagement portion 66 has a third extension portion 75 extending from the outer corner surface 65 and a fourth extension portion 76 extending from the third extension portion 75 in a direction different from that of the third extension portion 75. The first engagement portion 43 and the second engagement portion 66 have shapes that generally fit together. Because the first engagement portion 43 and the second engagement portion 66 extend in two different directions and engage in these two directions, an assembly support 1 can be provided that is less likely to slip or rattle and is highly stable.

In particular, the first extension portion 54 is a first horizontal extension portion 56 that extends substantially horizontally from the inner corner surface 42, the second extension portion 55 is a first vertical extension portion 57 that extends substantially vertically from the first horizontal extension portion 56, the third extension portion 75 is a second horizontal extension portion 77 that extends substantially horizontally from the outer corner surface 65, and the fourth extension portion 76 is a second vertical extension portion 78 that extends substantially vertically from the second horizontal extension portion 77. Because the first engagement portion 43 and the second engagement portion 66 extend in two substantially perpendicular directions and engage in these two directions, an assembly support 1 can be provided that is less likely to slip or rattle and has excellent stability.

A protrusion 58 is provided on one of the second extension portion 55 (first vertical extension portion 57) and the fourth extension portion 76 (second vertical extension portion 78), and a groove 79 that fits into the protrusion 58 is provided on the other of the second extension portion 55 (first vertical extension portion 57) and the fourth extension portion 76 (second vertical extension portion 78). By providing additional protrusions 58 and grooves 79 on the second extension portion 55 and the fourth extension portion 76, it is possible to provide an assembly support 1 that is less likely to slip and rattle, and has excellent stability.

The assembly support 1 also includes at least one restricting portion 59 provided on one of the inner corner surface 42 of the first support member 31 and the outer corner surface 65 of the second support member 32, and multiple restricting receiving portions 81 provided on the other of the inner corner surface 42 of the first support member 31 and the outer corner surface 65 of the second support member 32, which receive the restricting portion 59. The provision of the restricting portion 59 and the restricting receiving portions 81 limits the engagement range between the first engaging portion 43 of the first support member 31 and the second engaging portion 66 of the second support member 32, thereby increasing the strength and stability of the assembled support.

When the support strut is lengthened, the overlapping portion between the first support strut member 31 and the second support strut member 32 becomes shorter, but without a certain degree of overlap, the support strut's strength and stability cannot be maintained. Therefore, by providing a restricting portion 59 and a restricting receiving portion 81, a predetermined amount of overlap between the first support strut member 31 and the second support strut member 32 is ensured. For example, the restricting portion 59 is a convex portion located on the base end side of one of the first support strut member 31 and the second support strut member, and the restricting receiving portion 81 is a concave portion located from the base end side to the center of the other of the first support strut member 31 and the second support strut member 32. Because there is no restricting receiving portion on the tip side, a predetermined amount of overlap between the first support strut member 31 and the second support strut member 32 is ensured when the first support strut member 31 and the second support strut member 32 are assembled. Furthermore, when the restricting portion 59 and the restricting receiving portion 81 are engaged, the multiple first engaging portions 43 and second engaging portions 66 are engaged, thereby increasing the strength and stability of the support pole.

Furthermore, an assembly having such an assembly support 1, a first mounting section 11 connected to the tip of the assembly support 1, and a second mounting section 12 connected to the base end of the assembly support 1 can store and display items and merchandise of various heights by changing the length of the support and changing the spacing between the upper and lower mounting sections of the support, making it highly convenient. Unlike assembly supports that are lengthened by connecting multiple relatively short support members, the length of the support can be changed without changing the number of support members, eliminating the problem of having to store excess support members when the support is shortened. In addition to the small number of members that make up the support, the provision of multiple engagement sections at the corners makes it possible to provide an assembly that is less likely to shift or rattle.

The above describes an embodiment of the present invention, but various modifications and variations are possible without departing from the spirit of the present invention. For example, while a rack including caster units has been described as an assembly including an assembly support, the assembly support according to this embodiment can also be applied to assembly shelves without caster units. The number of mounting units is not limited to two; three or more mounting units may be connected by supports. The shape of the mounting units is also not limited to those disclosed herein. The mounting positions of the supports relative to the mounting units may be other than the four corners. The number of engagement units provided on the first support member and the second support member is also not limited to those disclosed herein. The materials of the mounting units and supports are also not limited to those disclosed herein.
