Description

The present invention relates to a hook mounting structure and a hook.

Patent Document 1 discloses a hook that is fixed to a wall surface using a screw member. This hook has a protrusion, and the mounting position and mounting direction relative to the wall surface are determined by inserting the protrusion into a positioning hole formed in the wall surface.

Patent No. 3911224

Incidentally, with the hook disclosed in Patent Document 1, the mounting position and direction are determined by inserting a protrusion into a positioning hole in the wall surface, but the mounting direction of the hook is limited to one direction and cannot be changed. In addition, with the hook disclosed in Patent Document 1, the user must insert the hook's protrusion into the positioning hole and then, while maintaining this state, secure the hook to the wall surface using a screw member, leaving room for improvement in ease of mounting.

In consideration of the above, the present invention aims to provide a hook mounting structure that allows the mounting direction of the hook to be changed as desired and allows the hook to be temporarily fixed to the mounting object. It also aims to provide a hook that allows the mounting direction to be changed as desired and allows the hook to be temporarily fixed to the mounting object.

The hook mounting structure of the first aspect of the present invention comprises a mounting member having a plate portion with a through hole formed therein and attached to a vehicle body, a hook having a shaft portion inserted into the through hole, a flange portion extending radially outward from the shaft portion and contacting the surface of the plate portion, and a hook portion provided on the surface of the flange portion, and attached to the vehicle body, and a direction changing mechanism having a plurality of locking portions provided at intervals around the through hole on the back surface of the plate portion, and a locked portion protruding radially outward from an insertion portion of the shaft portion inserted into the through hole and locked to the locking portion at a predetermined rotational position of the shaft portion.

In the first aspect of the hook attachment structure, the shank of the hook is inserted into a through hole formed in the plate portion of the attachment member. When the hook is rotated around the shank with the shank inserted into the through hole, the locked portion that rotates together with the shank is locked to the locking portion at a predetermined rotation position of the shank.
Here, in the hook mounting structure, multiple locking portions are provided at intervals around the through hole on the back surface of the plate portion, so the mounting direction of the hook can be changed as desired, compared to, for example, a configuration in which a single locking portion is provided on the back surface of the plate portion.
In the hook attachment structure, the locked portion is engaged with one of the multiple locking portions provided on the rear surface of the plate portion. By engaging the locked portion with the locking portion in this manner, the hook is temporarily fixed to the attachment member attached to the vehicle body. In other words, the hook is temporarily fixed to the vehicle body via the attachment member.

As described above, with the hook mounting structure of the first aspect, the mounting direction of the hook can be changed as desired, and the hook can be temporarily fixed to the vehicle body as the mounting target.

The second aspect of the hook mounting structure is the hook mounting structure of the first aspect, in which the orientation change mechanism has a plurality of the interlocking portions, and the plurality of the interlocking portions are provided on the shaft portion at intervals in the circumferential direction of the shaft portion.

In the second embodiment of the hook attachment structure, multiple interlocking portions are provided on the shaft portion at intervals in the circumferential direction of the shaft portion, so that the hook can be temporarily attached in a balanced manner compared to, for example, a configuration in which only one interlocking portion is provided on the shaft portion.

The hook mounting structure of the third aspect comprises a mounting member having a plate portion with a through hole formed therein and attached to the vehicle body, a hook having a shaft portion inserted into the through hole, a flange portion extending radially outward from the shaft portion and contacting the surface of the plate portion, and a hook portion provided on the surface of the flange portion, and attached to the vehicle body, and a direction changing mechanism having a plurality of interlocking portions provided on the shaft portion at intervals in the circumferential direction of the shaft portion and protruding radially outward from an insertion portion of the shaft portion inserted into the through hole, and an interlocking portion provided on the back surface of the plate portion and interlocking with the interlocking portions at a predetermined rotational position of the shaft portion.

In the hook attachment structure of the third aspect, the shank of the hook is inserted into a through hole formed in the plate portion of the attachment member. When the hook is rotated around the shank with the shank inserted into the through hole, the locked portion that rotates together with the shank is locked to the locking portion at a predetermined rotation position of the shank.
Here, in the hook mounting structure, multiple engaging portions are provided at intervals around the shaft portion, so the mounting direction of the hook can be changed as desired, compared to, for example, a configuration in which a single engaging portion is provided on the shaft portion.
In the hook attachment structure, one of the multiple engaged parts provided on the shaft is engaged with the engaging part. By engaging the engaged part with the engaging part in this manner, the hook is temporarily fixed to the attachment member attached to the vehicle body. In other words, the hook is temporarily fixed to the vehicle body via the attachment member.

As described above, with the hook mounting structure of the third aspect, the mounting direction of the hook can be changed as desired, and the hook can be temporarily fixed to the vehicle body as the mounting target.

The hook mounting structure of the fourth aspect is a hook mounting structure of any one of the first to third aspects, in which the engaging portion has a first protrusion protruding from the back surface of the plate portion, and a second protrusion protruding from the back surface of the plate portion, spaced apart from the first protrusion around the through hole, and having a protruding height lower than that of the first protrusion, and the engaged portion overcomes the second protrusion by the rotation of the shaft portion inserted into the through hole, and is engaged between the first and second protrusions.

In the fourth hook attachment structure, the engaged part climbs over the second protrusion and is engaged between the first and second protrusions by the simple operation of rotating the hook. In addition, in the above hook attachment structure, it is possible to determine that the engaged part is engaged with the engaging part by the resistance force that occurs when the engaged part climbs over the second protrusion.

The hook mounting structure of the fifth aspect is the hook mounting structure of the fourth aspect, in which the shaft portion is provided with a blocking portion that protrudes radially outward from the insertion portion of the shaft portion, and the blocking portion is disposed at a distance from the engaged portion in the circumferential direction of the shaft portion, and contacts the first protrusion when the shaft portion inserted into the through hole rotates, thereby blocking the rotation of the shaft portion.

In the fifth aspect of the hook attachment structure, a blocking portion is provided on the shaft, and this blocking portion comes into contact with the first protrusion as the shaft inserted into the through hole rotates, blocking the rotation of the shaft. Therefore, in the above hook attachment structure, it is possible to prevent the force that rotates the hook from acting on the blocked portion or being concentrated on the blocked portion, compared to a configuration in which the blocked portion comes into contact with the first protrusion to block the rotation of the shaft.

The sixth aspect of the hook mounting structure is the fifth aspect of the hook mounting structure, in which the length of the blocking portion in the protruding direction is shorter than the length of the engaged portion in the protruding direction, the second protrusion is disposed away from the edge of the through hole radially outward of the through hole, and the distance along the radial direction of the through hole from the edge of the through hole to the second protrusion is longer than the length of the blocking portion in the protruding direction.

In the hook mounting structure of the sixth aspect, the length of the blocking portion in the protruding direction is shorter than the length of the engaged portion in the protruding direction, and the distance from the edge of the through hole to the second protrusion along the radial direction of the through hole is longer than the length of the blocking portion in the protruding direction, so that even when the hook rotates, the blocking portion does not come into contact with the second protrusion. Therefore, in the above hook mounting structure, damage to the second protrusion can be suppressed compared to, for example, a configuration in which the blocking portion comes into contact with the second protrusion.

The seventh aspect of the hook mounting structure is the hook mounting structure of any one of the fourth to sixth aspects, in which the first protrusion has a first wall portion that extends from the edge of the through hole toward the radial outside of the through hole, and a second wall portion that extends from an end of the first wall portion along the edge of the through hole.

In the seventh aspect of the hook mounting structure, the first wall portion extends from the edge of the through hole toward the radially outward side of the through hole, and the second wall portion extends from the end of the first wall portion along the edge of the through hole. Therefore, in the above hook mounting structure, the first wall portion and the second wall portion constituting the first protrusion support each other, improving the rigidity of the first protrusion, for example, compared to when the first protrusion is composed of only the first wall portion.

The hook attachment structure of the eighth aspect is a hook attachment structure of any one of the first to fourth aspects, in which the through hole has a circular hole portion and a plurality of long hole portions extending radially outward from the edge of the circular hole portion, and the engaged portion passes through the long holes when the shaft portion is inserted into the circular hole portion.

In the hook attachment structure of the eighth aspect, the through hole is composed of a circular hole portion and multiple long hole portions, so rattling of the hook relative to the through hole can be suppressed compared to a configuration in which the through hole is an elliptical or polygonal hole, for example.

A ninth aspect of the hook mounting structure is the hook mounting structure of the fifth or sixth aspect, wherein the through hole has a circular hole portion and a plurality of elongated hole portions extending radially outward from an edge of the circular hole portion,
The engaged portion passes through the long hole portion when the shaft portion is inserted into the circular hole portion, and the blocking portion passes through the long hole portion adjacent to the long hole portion through which the engaged portion passes when the shaft portion is inserted into the circular hole portion.

In the ninth aspect of the hook attachment structure, the through hole is composed of a circular hole portion and multiple long hole portions, so rattling of the hook relative to the through hole can be suppressed compared to a configuration in which the through hole is an elliptical or polygonal hole, for example.

The hook mounting structure of the tenth aspect is the hook mounting structure of any one of the first to ninth aspects, in which the shaft portion is formed in a cylindrical shape, and the hook is attached to the vehicle body by threading a screw member through the inside of the shaft portion into a female thread portion of the vehicle body.

In the hook mounting structure of the tenth aspect, the hook is attached to the vehicle body by threading a screw member through the inside of the shaft and into the female thread of the vehicle body. Therefore, the above hook mounting structure can improve the mounting strength of the hook to the vehicle body compared to a structure in which the hook is attached to the vehicle body by, for example, hooking a claw portion provided on the shaft onto the edge of a through hole formed in the vehicle body.

The hook mounting structure of the eleventh aspect is the hook mounting structure of the first or second aspect, in which the locking portions are provided at equal intervals around the through hole on the back surface of the plate portion.

In the hook mounting structure of the 11th aspect, multiple locking portions are provided at equal intervals around the through hole on the back surface of the plate portion, so the mounting direction of the hook can be changed at any angle.

The twelfth aspect of the hook mounting structure is the second or third aspect of the hook mounting structure, in which the engaged portions are provided at equal intervals around the shaft portion.

In the twelfth embodiment of the hook attachment structure, multiple engaging portions are provided on the shaft at equal intervals in the circumferential direction of the shaft, so the attachment direction of the hook can be changed at any angle.

The hook of the thirteenth aspect has a plate portion with a through hole formed therein and a locking portion provided on the back surface of the plate portion, and is temporarily fixed to the vehicle body via a mounting member attached to the vehicle body, and is equipped with a shaft portion inserted into the through hole, a flange portion that protrudes radially outward from the shaft portion and contacts the surface of the plate portion, a hook portion provided on the surface of the flange portion, and a plurality of locked portions that are provided on the shaft portion at intervals in the circumferential direction of the shaft portion, protrude radially outward from an insertion portion of the shaft portion that is inserted into the through hole, and are locked to the locking portion at a predetermined rotational position of the shaft portion.

In the hook of the thirteenth aspect, the shaft portion is inserted into a through hole formed in the plate portion of the mounting member, and when the shaft portion is rotated around the shaft portion while inserted into the through hole, the locked portion, which rotates together with the shaft portion, is locked to the locking portion at a predetermined rotational position of the shaft portion.
Here, since the above-mentioned hook has multiple engaging portions spaced apart circumferentially around the shaft portion, the mounting direction of the hook can be changed as desired, compared to a configuration in which, for example, a single engaging portion is provided on the shaft portion.
In addition, in the above-mentioned hook, one of the multiple engaged parts provided on the shaft part is engaged with the engaging part. By engaging the engaged part with the engaging part in this manner, the hook is temporarily fixed to the mounting member attached to the vehicle body. In other words, the hook is temporarily fixed to the vehicle body via the mounting member.

As described above, the hook of the thirteenth aspect allows the mounting direction to be changed as desired, and can be temporarily fixed to the vehicle body as the mounting target.

According to the present invention, it is possible to provide a hook mounting structure that allows the mounting direction of the hook to be changed as desired and allows the hook to be temporarily fixed to the mounting object. It is also possible to provide a hook that allows the mounting direction to be changed as desired and allows the hook to be temporarily fixed to the mounting object.

Next, the hook mounting structure and hook according to one embodiment of the present invention will be described with reference to the drawings.

As shown in Figures 1 to 3, the hook 30 of this embodiment is a member that is attached to, for example, the ceiling portion 62 of the vehicle body 60. For example, a string-like member or the like is hooked onto this hook 30.

The hook mounting structure S1 of this embodiment is a structure for mounting the hook 30 to the vehicle body 60 via the mounting member 20. This hook mounting structure S1 includes the mounting member 20, the hook 30, and a direction changing mechanism 42.

<Mounting member 20>
As shown in Figures 1 to 4, the mounting member 20 is a member that constitutes part of a ceiling portion 62 of a vehicle body 60. As shown in Figures 2 and 3, the mounting member 20 of this embodiment is, as an example, an interior material that constitutes the ceiling portion 62. This mounting member 20 is attached to a frame 64 that constitutes the ceiling portion 62. In other words, the mounting member 20 is attached to the vehicle body 60. The mounting member 20 also has a plate portion 22 and a plurality of locking portions 26.

3, the plate portion 22 is attached to the metal plate 66 constituting the frame 64 of the mounting member 20. Specifically, the plate portion 22 is attached to the metal plate 66 together with the hook 30 by the screw member 50 with the back surface 22B in contact with the surface of the metal plate 66. The plate portion 22 has a through hole 23 penetrating in the plate thickness direction. The shaft portion 32 of the hook 30 described later is inserted into the through hole 23. A female thread portion 68 is provided at a position corresponding to the through hole 23 of the metal plate 66. Specifically, the metal plate 66 has a mounting hole 70 formed at a position that fits inside the through hole 23 when the plate portion 22 is in contact with the metal plate 66. A nut 72 is welded to the back surface of the metal plate 66 at the mounting hole 70. The female thread portion of the nut 72 is the female thread portion 68 described above. The screw member 50 is screwed into the female thread portion 68. In this embodiment, the female thread portion 68 is the female thread portion of the nut 72, but the present invention is not limited to this configuration. For example, the female thread portion may be machined into the metal plate 66. In this embodiment, a shoulder bolt is used as an example of the screw member 50, but the present invention is not limited to this configuration.

4, the through hole 23 has a circular hole portion 24 and a plurality of long hole portions 25. The circular hole portion 24 is a circular hole portion when the plate portion 22 is viewed from the plate thickness direction. The long hole portion 25 is a hole portion extending radially outward from the edge 24A of the circular hole portion 24 when the plate portion 22 is viewed from the plate thickness direction. The plurality of long hole portions 25 are arranged at intervals in the circumferential direction of the circular hole portion 24. Specifically, the plurality of long hole portions 25 are arranged at equal intervals in the circumferential direction of the circular hole portion 24. In other words, the plurality of long hole portions 25 are arranged at equal angles with the circular hole portion 24 as the center. In this embodiment, as an example, the through hole 23 has four long hole portions 25, and the four long hole portions 25 are arranged at equal intervals in the circumferential direction of the circular hole portion 24. That is, the four long hole portions 25 are provided at intervals of 90 degrees with the circular hole portion 24 as the center. In other words, the through hole 23 has two pairs of long hole portions 25 that extend in opposite directions from each other relative to the circular hole portion 24. In this embodiment, the shaft portion 32 of the hook 30 is inserted into the circular hole portion 24 of the through hole 23.

As shown in FIG. 13, the locking portion 26 is a portion that locks the locked portion 38 of the hook 30. As shown in FIG. 4, the multiple locking portions 26 are provided on the back surface 22B of the plate portion 22. Specifically, the multiple locking portions 26 are provided at intervals around the through hole 23 on the back surface 22B of the plate portion 22. Specifically, the multiple locking portions 26 are provided at equal intervals in the circumferential direction around the circular hole portion 24 on the back surface 22B of the plate portion 22. In other words, the multiple locking portions 26 are provided at equal angles around the circular hole portion 24 on the back surface 22B of the plate portion 22 with the circular hole portion 24 as the center. In this embodiment, as an example, four locking portions 26 are provided at equal intervals in the circumferential direction around the circular hole portion 24 on the back surface 22B of the plate portion 22. That is, the four locking portions 26 are provided around the circular hole portion 24 on the back surface 22B of the plate portion 22 at intervals of 180 degrees with the circular hole portion 24 as the center. In other words, each locking portion 26 is disposed between adjacent long hole portions 25 in the circumferential direction of the circular hole portion 24.

As shown in FIG. 4, the locking portion 26 has a first protrusion 27 and a second protrusion 28.

The first protrusion 27 is a portion provided on the back surface 22B of the plate portion 22 and protruding from the back surface 22B. The first protrusion 27 has a first wall portion 27A and a second wall portion 27B. The first wall portion 27A extends from the edge of the through hole 23 toward the radially outer side of the through hole 23. Specifically, the first wall portion 27A extends from the edge 24A of the circular hole portion 24 toward the radially outer side of the circular hole portion 24. The second wall portion 27B extends from the end portion 27A1 of the first wall portion 27A along the edge of the through hole 23. Specifically, the second wall portion 27B extends from the end portion 27A1 of the first wall portion 27A on the radially inner side of the circular hole portion 24 of the circular hole portion 24 along the edge of the circular hole portion 24 in the circumferential direction of the circular hole portion 24.

The second protrusion 28 is a portion provided on the back surface 22B of the plate portion 22 and protruding from the back surface 22B. The second protrusion 28 is provided around the through hole 23 at a distance from the first protrusion 27. Specifically, the second protrusion 28 is provided around the circular hole portion 24 at a distance from the first protrusion 27 in the circumferential direction of the circular hole portion 24. The protruding height of the second protrusion 28 is lower than the protruding height of the first protrusion 27. Specifically, the protruding height of the second protrusion 28 is set to a height at which the engaged portion 38 of the hook 30 can be overcome (see Figures 14 and 15). As an example, in this embodiment, the cross-sectional shape of the second protrusion 28 is approximately semicircular. The cross-sectional shape of the second protrusion 28 here is the shape in a cross section obtained by cutting the second protrusion 28 along the circumferential direction of the circular hole portion 24. In addition, the second protrusion 28 is disposed at a distance from the edge of the through hole 23 to the radially outer side of the through hole. Specifically, the second protrusion 28 is disposed at a distance from the edge 24A of the circular hole portion 24 to the radially outer side of the circular hole portion 24.

<Hook 30>
As described above, the hook 30 is a member attached to the ceiling portion 62 of the vehicle body 60, and is designed so that a string-like member or the like can be hooked onto the hook portion 36, which will be described later. As shown in Figures 5 to 11, the hook 30 has a shaft portion 32, a flange portion 34, a hook portion 36, and a plurality of engaged portions 38.

As shown in FIG. 4, the shaft portion 32 is the portion that is inserted into the through hole 23 of the hook 30. This shaft portion 32 is formed in a tubular shape. In the present embodiment, as an example, the shaft portion 32 is formed in a cylindrical shape. Furthermore, a screw member 50 is inserted into the inside of the shaft portion 32. Specifically, the hook 30 is attached to the vehicle body 60 by threading the screw member 50 through the inside of the shaft portion 32 and into the female thread portion 68 of the metal plate 66 (see FIG. 4).

As shown in FIG. 5, the shaft diameter D1 of the shaft portion 32 (see FIG. 10) is smaller than the hole diameter D2 of the through hole 23 (see FIG. 4). Here, the hole diameter of the through hole refers to the diameter of the inscribed circle inscribed in the polygon when the through hole is polygonal, and refers to the minor axis of the ellipse when the through hole is elliptical. In this embodiment, the diameter of the circular hole portion 24 corresponds to the hole diameter D2 of the through hole 23. In addition, it is preferable to set the difference between the shaft diameter D1 and the hole diameter D2 to such an extent that the multiple blocking portions 40 are caught on the edge of the through hole 23 when the shaft portion 32 is in contact with the edge of the through hole 23 (see FIG. 18). Specifically, it is preferable to set the hole diameter D2 in the range of 1.05 to 1.25 times the shaft diameter D1, and more preferably in the range of 1.1 to 1.2 times. By setting the shaft diameter D1 and hole diameter D2 in this way, a predetermined amount of clearance is secured between the outer periphery of the shaft portion 32 and the edge 24A of the circular hole portion 24. As a result, even if the center of the mounting hole 70 of the metal plate 66 is misaligned with the center of the circular hole portion 24, the axis of the shaft portion 32 can be aligned with the center of the mounting hole 70, and the screw member 50 can be securely screwed into the female thread portion 68.

As shown in Figures 5 and 9, the flange portion 34 is a portion that protrudes radially outward from the shaft portion 32 of the hook 30. This flange portion 34 is formed in an annular shape (see Figure 10). Furthermore, the flange portion 34 contacts the surface 22A of the plate portion 22 when the hook 30 is attached to the vehicle body 60. Specifically, the back surface 34B of the flange portion 34 contacts the surface 22A of the plate portion 22.

As shown in Figures 5, 6 and 9, the hook portion 36 is a portion provided on the surface 34A of the flange portion 34 of the hook 30, and is used to hook, for example, a string-like member.

As shown in FIG. 13, the locked portion 38 is a portion that is locked to the locking portion 26 of the plate portion 22. The locked portion 38 protrudes radially outward from the insertion portion 33 of the shaft portion 32. Here, the insertion portion 33 of the shaft portion 32 refers to the portion that is inserted into the through hole 23 when the shaft portion 32 is inserted into the through hole 23. The locked portion 38 is plate-shaped with its thickness direction being the axial direction of the shaft portion 32, and can bend in the thickness direction (see FIG. 14).

As shown in FIG. 10, the multiple locked portions 38 are provided on the shaft portion 32 at intervals in the circumferential direction of the shaft portion 32. Specifically, the multiple locked portions 38 are provided on the shaft portion 32 at equal intervals in the circumferential direction of the shaft portion 32. In other words, the multiple locked portions 38 are provided on the shaft portion 32 at equal angles with the shaft portion as the center. In this embodiment, as an example, two locked portions 38 are provided on the shaft portion 32 at equal intervals in the circumferential direction of the shaft portion 32. That is, the two locked portions 38 are provided at 180 degree intervals with the shaft portion 32 as the center. In other words, the two locked portions 38 protrude in opposite directions with the shaft portion 32 as the center.

12, when the shaft portion 32 is inserted into the circular hole portion 24, the multiple interlocking portions 38 pass through the elongated hole portion 25. Specifically, the rotation angle of the shaft portion 32 is adjusted and the shaft portion 32 is inserted into the circular hole portion 24 so that the interlocking portions 38 pass through the elongated hole portion 25, thereby causing the interlocking portions 38 to pass through the elongated hole portion 25. The interlocking portions 38 climb over the second protrusion 28 due to the rotation of the shaft portion 32 inserted into the through hole 23, and are interlocked between the first protrusion 27 and the second protrusion 28. In other words, when the locked portion 38 rotates with the rotation of the shaft portion 32 inserted into the through hole 23 and comes into contact with the second protrusion 28, the locked portion 38 bends in the thickness direction and climbs over the second protrusion 28 (see FIG. 14), and is locked (in other words, held) between the first protrusion 27 and the second protrusion 28 (see FIG. 13 and FIG. 15). In this way, the locked portion 38 is locked to the locking portion 26 at a predetermined rotation position of the shaft portion 32.

As shown in FIG. 10, the shaft portion 32 is provided with a plurality of blocking portions 40 that protrude radially outward from the insertion portion of the shaft portion 32. The blocking portions 40 are provided on the shaft portion 32 at intervals in the circumferential direction of the shaft portion 32. Specifically, the blocking portions 40 are provided on the shaft portion 32 at equal intervals in the circumferential direction of the shaft portion 32. In other words, the blocking portions 40 are provided on the shaft portion 32 at equal angles with the shaft portion 32 as the center. In this embodiment, as an example, two blocking portions 40 are provided on the shaft portion 32 at equal intervals in the circumferential direction of the shaft portion 32. That is, the two blocking portions 40 are provided at intervals of 180 degrees with the shaft portion 32 as the center. In other words, the two blocking portions 40 protrude in opposite directions with the shaft portion 32 as the center.
Moreover, the blocking portion 40 is disposed at a distance from the locked portion 38 in the circumferential direction of the shaft portion 32. Specifically, the blocking portion 40 is disposed at a position spaced 90 degrees from the locked portion 38 with the shaft portion 32 as the center.

As shown in FIG. 12, when the shaft portion 32 is inserted into the circular hole portion 24, the multiple blocking portions 40 pass through the long hole portion 25. Specifically, when the shaft portion 32 is inserted into the circular hole portion 24, the blocking portions 40 pass through the long hole portion 25 adjacent to the long hole portion 25 through which the locked portion 38 passes. Specifically, by adjusting the rotation angle of the shaft portion 32 and inserting the shaft portion 32 into the circular hole portion 24, the locked portion 38 passes through the long hole portion 25, and the blocking portions 40 pass through the long hole portion 25 adjacent to the long hole portion 25 through which the locked portion 38 passes. Then, due to the rotation of the shaft portion 32 inserted into the through hole 23, the blocking portions 40 come into contact with the first protrusion 27, blocking the rotation of the shaft portion 32 (see FIG. 13).

10, the length L2 of the blocking portion 40 in the protruding direction is shorter than the length L1 of the locked portion 38 in the protruding direction. Here, the length L2 of the blocking portion 40 in the protruding direction is the distance measured from the root to the tip of the blocking portion 40 along the radial direction of the shaft portion 32. Also, the length L1 of the locked portion 38 in the protruding direction is the distance measured from the root to the tip of the locked portion 38 along the radial direction of the shaft portion 32. Also, the length L2 of the blocking portion 40 is shorter than the distance L3 (see FIG. 4) along the radial direction of the through hole 23 from the edge of the through hole 23 to the second protrusion 28. Specifically, the length L2 of the blocking portion 40 is shorter than the distance L3 from the edge 24A of the circular hole portion 24 to the radially inner end of the circular hole portion 24 at the second protrusion 28. In other words, the distance L3 is longer than the length L2. Therefore, even if the hook 30 rotates, the blocking portion 40 contacts the first protrusion 27 but does not contact the second protrusion 28.

<Orientation change mechanism 42>
1 to 3, the orientation change mechanism 42 is a mechanism for arbitrarily changing the attachment direction of the hook 30. This orientation change mechanism 42 has a plurality of locking portions 26 and a plurality of locked portions 38. The locking portions 26 and the locked portions 38 are as described above.

In this embodiment, the hook 30 is an integrally molded resin product as an example, but the present invention is not limited to this configuration.

Next, the operation and effects of this embodiment will be described.
In the hook mounting structure S1 of this embodiment, the shaft portion 32 of the hook 30 is inserted into the through hole 23 formed in the plate portion 22 of the mounting member 20. When the hook 30 is rotated around the shaft portion 32 with the shaft portion 32 inserted into the through hole 23, the locked portion 38, which rotates together with the shaft portion 32, is locked to the locking portion 26 at a predetermined rotation position of the shaft portion 32.
Here, in the hook mounting structure S1, multiple locking portions 26 are provided at intervals around the through hole 23 on the back surface 22B of the plate portion 22, so that the mounting direction of the hook can be changed as desired, compared to a configuration in which, for example, one locking portion 26 is provided on the back surface 22B of the plate portion 22.
In the hook mounting structure S1, the locked portion 38 is locked to one of the locking portions 26 among the multiple locking portions 26 provided on the back surface 22B of the plate portion 22. By locking the locked portion 38 to the locking portion 26 in this manner, the hook 30 is temporarily fixed to the mounting member 20 attached to the vehicle body 60. In other words, the hook 30 is temporarily fixed to the vehicle body 60 via the mounting member 20.

As described above, the hook mounting structure S1 of this embodiment allows the mounting direction of the hook 30 to be changed as desired, and allows the hook 30 to be temporarily fixed to the vehicle body 60 as the mounting object, as shown in Figures 16 and 17. Furthermore, the mounting direction of the hook 30 of this embodiment can be changed as desired, and allows the hook 30 to be temporarily fixed to the mounting object.

In addition, in the hook mounting structure S1 of this embodiment, multiple interlocking portions 38 are provided on the shaft portion 32 at intervals in the circumferential direction of the shaft portion 32, so that the hook 30 can be balanced in a provisionally fastened state, compared to, for example, a configuration in which only one interlocking portion 38 is provided on the shaft portion. In particular, in this embodiment, the interlocking portions 38 extend in opposite directions from each other from the shaft portion 32, so that it is easy to balance the hook in a provisionally fastened state.

In addition, in the hook mounting structure S1 of this embodiment, when the hook 30 is rotated, the engaged portion 38 rotates together with the shaft portion 32, and passes over the second protrusion 28 to be engaged between the first protrusion 27 and the second protrusion 28. Here, in the hook mounting structure S1, the engaged portion 38 passes over the second protrusion 28 and is engaged between the first protrusion 27 and the second protrusion 28 by the simple operation of rotating the hook 30. In addition, in the hook mounting structure S1, the user can recognize that the engaged portion 38 has passed over the second protrusion 28 due to the resistance force generated when the engaged portion 38 passes over the second protrusion 28. In other words, the user can determine whether the engaged portion 38 is engaged with the engaging portion 26 or not by the rotation of the hook 30.

In addition, in the hook mounting structure S1 of this embodiment, a blocking portion 40 is provided on the shaft portion 32, and this blocking portion 40 comes into contact with the first protrusion 27 as the shaft portion 32 inserted into the through hole 23 rotates, blocking the rotation of the shaft portion 32. Therefore, in the hook mounting structure S1, it is possible to prevent the force that rotates the hook 30 from acting on the locked portion 38 or being concentrated on the locked portion 38, compared to a configuration in which the locked portion 38 comes into contact with the first protrusion 27 to block the rotation of the shaft portion 32, for example.

In addition, in the hook mounting structure S1 of this embodiment, the length L2 of the blocking portion 40 is shorter than the length L1 of the engaged portion 38, and the distance L3 along the radial direction of the through hole 23 from the edge of the through hole 23 to the second protrusion 28 is longer than the length L2 of the blocking portion 40. Therefore, in the hook mounting structure S1, the blocking portion 40 does not come into contact with the second protrusion 28 when the hook 30 rotates. Therefore, in the hook mounting structure S1, damage to the second protrusion 28 can be suppressed compared to, for example, a configuration in which the blocking portion 40 comes into contact with the second protrusion 28.

In addition, in the hook mounting structure S1 of this embodiment, the first wall portion 27A extends from the edge of the through hole 23 toward the radial outside of the through hole 23, and the second wall portion 27B extends from the end portion 27A1 of the first wall portion 27A along the edge of the through hole 23. Specifically, the first wall portion 27A extends from the edge 24A of the circular hole portion 24 toward the radial outside of the through hole 23, and the second wall portion 27B extends from the end portion 27A1 of the first wall portion 27A along the edge 24A of the circular hole portion 24. Therefore, in the hook mounting structure S1, the first wall portion 27A and the second wall portion 27B that constitute the first protrusion 27 support each other, and the rigidity of the first protrusion 27 is improved, for example, compared to when the first protrusion 27 is composed only of the first wall portion 27A.

In addition, in the hook mounting structure S1 of this embodiment, the through hole 23 is configured with a circular hole portion 24 and multiple long hole portions 25, so rattling of the hook 30 relative to the through hole 23 can be suppressed compared to a configuration in which the through hole 23 is an elliptical hole or a polygonal hole, for example.

In addition, in the hook mounting structure S1 of this embodiment, the hook 30 is attached to the vehicle body 60 by threading the screw member 50 through the inside of the shaft portion 32 and into the female thread portion 68 of the vehicle body 60. Therefore, in the hook mounting structure S1, the mounting strength of the hook 30 to the vehicle body 60 can be improved compared to a structure in which the hook is attached to the vehicle body 60 by, for example, hooking a claw portion provided on the shaft portion onto the edge of a through hole 23 formed in the vehicle body 60.

In addition, in the hook mounting structure S1 of this embodiment, multiple locking portions 26 are provided at equal intervals around the through hole 23 on the back surface 22B of the plate portion 22. Specifically, multiple locking portions 26 are provided at equal intervals around the circular hole portion 24 on the back surface 22B of the plate portion 22. Therefore, in the hook mounting structure S1, the mounting direction of the hook 30 can be changed at any angle.

Other Embodiments
In the hook mounting structure S1 of the above embodiment, the orientation change mechanism 42 is composed of the locking portion 26 and the locked portion 38, but the present invention is not limited to this configuration. For example, a structure like the hook mounting structure S2 shown in Figs. 19 to 21 may be used. The hook mounting structure S2 includes a mounting member 80, a hook 84, and an orientation change mechanism 90. As shown in Fig. 20, the mounting member 80 has a plurality of locking portions 82 instead of the plurality of locking portions 26 of the mounting member 20. The mounting member 80 has substantially the same configuration as the mounting member 20 except for the configuration of the locking portions 82. The plurality of locking portions 82 are provided at intervals around the through hole 23 on the back surface 22B of the plate portion 22. The locking portions 82 are recessed portions provided on the back surface 22B of the plate portion 22. The convex portions of the locked portions 86 of the hooks 84 fit into these recessed portions (see Fig. 19). As shown in FIG. 21, the hook 84 has a plurality of engaged parts 86 instead of the plurality of engaged parts 38 of the hook 30. The hook 84 has a configuration substantially the same as the hook 30 except for the configuration without the blocking part 40 and the configuration of the engaged parts 86. The plurality of engaged parts 86 are provided on the shaft part 32 at intervals in the circumferential direction of the shaft part 32. The engaged parts 86 protrude radially outward from the insertion part 33 of the shaft part 32. A convex part 86B that fits into the concave engaging part 82 is provided at the tip part 86A in the protruding direction of the engaged parts 86. The convex part 86B protrudes toward the insertion direction side into the through hole 23 of the shaft part 32. The size of the concave engaging part 82 is larger than the convex part 86B. Therefore, the convex part 86B can move inside the concave engaging part 82. The depth of the recessed locking portion 82 is set to such an extent that the deformation of the plate-like portion of the locked portion 86 allows the convex portion 86B to overcome the step between the rear surface 22B and the locking portion 82. The outer shape of the convex portion 86B may be set to a semicircular shape. The orientation change mechanism 90 is composed of the locking portion 82 and the locked portion 86.
In the hook mounting structure S2, when the hook 84 is rotated around the shaft portion 32 with the shaft portion 32 inserted in the through hole 23, the locked portion 86, which rotates together with the shaft portion 32, is locked to the locking portion 82 at a predetermined rotational position of the shaft portion 32. Specifically, the locked portion 86 fits into the locking portion 82 and is locked to the inside of the locking portion 82. Therefore, similar to the hook mounting structure S1, the hook mounting structure S2 allows the mounting direction of the hook 84 to be changed as desired, and allows the hook 84 to be temporarily fixed to the vehicle body 60 as the mounting target.

In the hook mounting structure S1 of the above embodiment, the shaft portion 32 is provided with multiple interlocking portions 38, but the present invention is not limited to this configuration. For example, the shaft portion 32 may be provided with one interlocking portion 38. In this case, as with the hook mounting structure S1, the mounting direction of the hook 30 can be changed as desired, and the hook 30 can be temporarily fixed to the vehicle body 60 as the mounting target. The above configuration of providing one interlocking portion 38 on the shaft portion 32 may also be applied to the hook mounting structure S2.

In the hook mounting structure S1 of the above embodiment, multiple locking portions 26 are provided on the back surface 22B of the plate portion 22, but the present invention is not limited to this configuration. For example, a single locking portion 26 may be provided on the back surface 22B of the plate portion 22. In this case, as with the hook mounting structure S1, the mounting direction of the hook 30 can be changed as desired, and the hook 30 can be temporarily fixed to the vehicle body 60 as the mounting target. By replacing the blocking portion 40 of the hook 30 with the locked portion 38, the mounting direction of the hook 30 can be changed every 90 degrees. The above-mentioned configuration of providing a single locking portion 26 on the back surface 22B of the plate portion 22 may also be applied to the hook mounting structure S2.

In the hook mounting structure S2 of the above embodiment, the convex portion 86B of the engaged portion 86 fits into the concave engaging portion 82, thereby engaging the engaged portion 86 with the engaging portion 82, but the present invention is not limited to this configuration. For example, a convex portion may be provided on the back surface 22B of the plate portion 22, and a concave portion into which the convex portion fits may be provided at the tip end 86A of the engaged portion 86. Even in this case, the same effect as the hook mounting structure S2 can be obtained.

In the hook mounting structure S1 of the above embodiment, the shaft 32 is provided with multiple interlocking portions 38 and multiple blocking portions 40, but the present invention is not limited to this configuration. For example, the shaft 32 may be configured to have only multiple interlocking portions 38. In this case, the interlocking portions 38 come into contact with the first protrusion 27 to prevent the shaft 32 from rotating. Also, the same effect as the hook mounting structure S1 can be obtained.

In the hook mounting structure S1 of the above embodiment, the first protrusion 27 is composed of the first wall portion 27A and the second wall portion 27B, but the present invention is not limited to this configuration. For example, the first protrusion 27 may be composed of only the first wall portion 27A. In addition, the second wall portion 27B extends from the end portion 27A1 of the first wall portion 27A, but may be provided in any part as long as it is in contact with the blocking portion 40 of the first wall portion 27A.

In the hook mounting structure S1 of the above embodiment, the through hole 23 is configured with a circular hole portion 24 and multiple long hole portions 25, but the present invention is not limited to this configuration. For example, the through hole 23 may be an elliptical hole or a polygonal hole. Even in this case, the same effect as the hook mounting structure S1 can be obtained. Note that the configuration in which the through hole 23 is an elliptical hole or a polygonal hole may be applied to the hook mounting structure S2.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and it is of course possible to implement the invention in various other modified forms without departing from the spirit of the invention.
