DETAILED DESCRIPTION

[0023] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0024] Figure 1 It is a diagram schematically showing a vehicle hook device according to an embodiment of the present invention. Figure 1 The X-axis, Y-axis, and Z-axis are depicted in FIG. Figure 1 In the diagram, the left and right directions are referred to as the front-back direction or the X direction, the left direction is referred to as the front direction, the front side or the "+X direction", and the right direction is referred to as the rear direction, the rear side or the "-X direction". In addition, the up and down directions are referred to as the vehicle height direction, the interior and exterior direction of the vehicle or the Y direction, the top is referred to as the interior side or the "+Y direction", and the bottom is referred to as the exterior side or the "-Y direction". In addition, the depth direction is referred to as the vehicle width direction or the Z direction. In addition, Figure 1 In the diagram, the direction of raising the hook member 20 (described later) is referred to as the clockwise direction or the “raising direction” and is indicated by “CW1”. The direction of lowering the hook member 20 is referred to as the counterclockwise direction or the “lowering direction” and is indicated by “CW2”.

[0025] Figure 1 1 , which constitutes an interior material of a vehicle cabin, is shown. A vehicle hook device 10 according to this embodiment is attached to the panel member 1 .

[0026] The panel member 1 includes a surface 1a facing the interior of the vehicle (in the +Y direction), a recessed storage portion 1b recessed from the surface 1a toward the exterior (in the -Y direction), and an opening 1c. The opening 1c is formed in the center of the storage portion 1b, connecting the interior and exterior of the vehicle. A front edge 1d of the opening 1c includes a front sidewall 1f extending to the exterior. Furthermore, a rear edge 1e of the opening 1c includes a rear sidewall 1g extending to the exterior.

[0027] The panel member 1 has a cylindrical rotation shaft 2. The rotation shaft 2 extends in the vehicle width direction (Z direction).

[0028] The vehicle hook device 10 according to this embodiment includes the hook member 20. The hook member 20 includes a vehicle interior hook 20A disposed inside the vehicle interior (+Y direction) and a vehicle exterior hook 20B disposed outside the vehicle exterior (-Y direction).

[0029] Figure 2 yes Figure 1 II-direction view. Figure 2 As shown, the hook member 20 is housed in the storage portion 1b. The interior hook 20A and the exterior hook 20B are assembled together. The interior hook 20A has a pair of flanges 31, which are arranged on either side in the vehicle width direction (Z direction) and extend in the front-to-back direction (X direction). The exterior hook 20B is inserted between the flanges 31. The storage portion 1b has two side walls 1j, which are arranged on either side in the vehicle width direction (Z direction) and extend in the front-to-back direction. Figure 2 The rotating shaft 2 shown by the dotted line is protruded from both side walls 1 j toward the pair of flanges 31 .

[0030] like Figure 1 and Figure 2As shown, the interior hook 20A of the vehicle interior has a fitting portion 32. The fitting portion 32 is formed on the flange 31 and is fitted so as to be rotatable around the rotating shaft 2. The fitting portion 32 has a pair of clamping pieces 32a. The pair of clamping pieces 32a are respectively elastic and are arranged opposite to each other across the rotating shaft 2 to clamp the rotating shaft 2. When the hook component 20 is assembled to the panel component 1, the pair of clamping pieces 32a are pressed with a predetermined force from a direction perpendicular to the axis of the rotating shaft 2 toward the side of the rotating shaft 2. As a result, the gap between the pair of clamping pieces 32a is expanded to be larger than the diameter of the rotating shaft 2, and then the pair of clamping pieces 32a are closed, thereby clamping the rotating shaft 2, and the fitting portion 32 is fitted to the rotating shaft 2. As a result, the hook component 20 can be easily assembled to the panel component 1. On the contrary, when a force (pulling force) that expands the gap between the pair of clamping pieces 32a to a value greater than the diameter of the rotating shaft 2 overcomes the elastic force of the pair of clamping pieces 32a and is applied to the fitting portion 32, the fitting portion 32 falls off from the rotating shaft 2. As a result, the hook member 20 falls off from the panel member 1.

[0031] Figure 3 2 is a diagram schematically showing the vehicle hook device 10 when the hook member 20 is in the use position. Figure 3 In FIG. 1 , the hook member 20 at the storage position is shown by a dotted line, and the hook member 20 at the use position is shown by a solid line. The hook member 20 is supported by the shaft 2 so as to be able to move in the storage position ( Figure 1 Position shown) and use position ( Figure 3 In the stored position, the hook member 20 tilts toward the panel member 1, i.e., in the counterclockwise direction CW2, and is stored in the storage portion 1b. The hook member 20 then rises from the storage portion 1b in the clockwise direction CW1, thereby moving to the use position. In the use position, objects can be hooked onto the hook member 20. At this time, the load applied to the hook member 20 acts as a force that rotates the hook member 20 in the clockwise direction CW1 (the rising direction).

[0032] The exterior hook 20B includes a leg portion 22. The leg portion 22 extends from the interior side (+Y direction) to the exterior side (-Y direction) through the opening 1c. Hereinafter, when describing the leg portion 22, the interior side may be referred to as the "base end side" and the exterior side may be referred to as the "front end side."

[0033] The front side edge 22a of the leg 22 is provided with a claw 24. The claw 24 corresponds to the "locking portion" of the present invention. The claw 24 is a convex portion protruding forward (+X direction). When a load is applied to the hook component 20 in the use position, the claw 24 is locked with the front side edge 1d of the opening 1c so that the hook component 20 does not stand up from the use position. The front side edge 1d is formed with a groove having the same cross-sectional shape as the V-shaped cross-sectional shape of the front end of the claw 24. By locking the claw 24 with the front side edge 1d, the hook component 20 is prevented from rotating in the clockwise direction CW1 (standing direction), so that an allowable load can be applied to the hook component 20. The allowable load corresponds to the "first load" of the present invention.

[0034] When an excessive load is applied to the claw portion 24 or the front side edge portion 1 d due to a load exceeding the allowable load applied to the hook member 20 , the claw portion 24 or the front side edge portion 1 d may be damaged.

[0035] Therefore, in this embodiment, the exterior hook 20B is provided with a fragile portion 26. When an overload (corresponding to the "second load" of the present invention) is applied to the hook member 20, the fragile portion 26 deforms to break free from the engagement of the claw portion 24 with the front edge 1d. Specifically, the fragile portion 26 is positioned within the leg 22, closer to the interior (base end) than the claw portion 24. By recessing the fragile portion 26 within the rear edge 22b of the leg 22, the wall thickness of the fragile portion 26 is reduced compared to the surrounding wall thickness of the fragile portion 26. In other words, the base end and the front end of the fragile portion 26 of the leg 22 are thicker than the fragile portion 26.

[0036] When the hook member 20 is located Figure 1 When the hook member 20 is in the storage position shown, for example, it may be lifted upward. Figure 1 If the hook member 20 is not prevented from moving in the counterclockwise direction CW2, the rotating shaft 2 may fall out from between the pair of clamping pieces 32a, causing the hook member 20 to fall off the panel member 1.

[0037] Therefore, in this embodiment, the exterior hook 20B is provided with an abutment portion 28. The abutment portion 28 corresponds to the "anti-falling portion" of the present invention. When a load is applied to the hook component 20 in the counterclockwise direction CW2 (falling direction) from the storage position, the abutment portion 28 abuts against the front end portion of the rear side wall 1g of the opening portion 1c to prevent the hook component 20 from moving in the counterclockwise direction CW2. The abutment portion 28 is a protrusion that is arranged on the rear side edge 22b of the leg 22 and protrudes from the rear side edge 22b in the rear direction (-X direction). By the abutment of the abutment portion 28 with the front end portion of the rear side wall 1g, the hook component 20 can be prevented from falling off from the panel component 1.

[0038] The contact portion 28 and the fragile portion 26 are formed on the same component (for example, the leg 22). Specifically, the contact portion 28 is arranged in the leg 22 at a position closer to the outside of the vehicle interior (the front end side) than the position where the fragile portion 26 is arranged. In other words, the fragile portion 26 is arranged closer to the inside of the vehicle interior (the base end side) than the contact portion 28. The movable range of the hook component 20 in the rotational direction is the range from the position where the claw portion 24 abuts the front side edge 1d to the position where the rear side edge 22b abuts the rear side wall 1g. Therefore, if the number of components passing through the opening 1c increases, the movable range becomes narrower accordingly. In this embodiment, the contact portion 28 and the fragile portion 26 are formed on the same component, namely the leg 22, so the movable range of the hook component 20 can be expanded compared to the case where they are formed on different components.

[0039] And, as Figure 1 As shown, the fragile portion 26 is arranged closer to the inner side of the vehicle interior (base end side) than the abutment portion 28. Therefore, when the hook component located in the storage position is subjected to a load in the falling direction, the fragile portion 26 may be deformed, causing the abutment portion 28 to fall off from the front end portion of the rear side wall 1g of the opening portion 1c.

[0040] Therefore, in this embodiment, a retaining portion 3 is provided to prevent deformation of the fragile portion 26 when a load in the falling direction is applied to the hook member in the stored position. Specifically, the retaining portion 3 is the rear side wall 1g of the opening 1c. The retaining portion 3, i.e., the rear side wall 1g, abuts against and supports the base and front ends of the fragile portion 26 in the leg portion 22, which is thicker than the fragile portion 26, thereby retaining the fragile portion 26. This prevents deformation of the fragile portion 26. Furthermore, the abutment portion 28 is prevented from being released from its contact with the front end of the rear side wall 1g of the opening 1c.

[0041] Next, refer to Figure 4 The effect of the load applied to the hook member 20 will be described. Figure 4As shown, a load applied to the hook component 20 in the use position generates a clockwise torque T1 CW1 that rotates the hook component 20 in the upright direction. Furthermore, a reaction force R1 is generated in the claw portion 24 engaged with the front edge 1d of the opening 1c, and a reaction force R2 is generated in the portion contacting the rear end 1h of the storage portion 1b, relative to the load applied to the hook component 20. The clockwise torque T1 CW1 generated by the load is balanced by the counterclockwise torque T2 CW2 generated by the reaction forces R1 and R2. Thus, the hook component 20 is maintained in the use position. At this time, a load that would increase the distance between the pair of clamping pieces 32a to a value greater than the diameter of the rotating shaft 2 is not applied to the hook component 20.

[0042] On the other hand, if the hook member 20 is overloaded and the fragile portion 26 is deformed, causing the claw portion 24 to break free from its engagement with the front edge 1d, a clockwise torque CW1 is generated with the rear end 1h of the housing portion 1b as a fulcrum relative to the hook member 20. Consequently, a force is applied to the engaging portion 32, which increases the distance between the pair of clamping pieces 32a to a value greater than the diameter of the rotating shaft 2. As a result, the engaging portion 32 is disengaged from the rotating shaft 2, and the hook member 20 itself is disengaged from the panel member 1, thereby preventing the rotating shaft 2 from being deformed or damaged.

[0043] The vehicle hook device 10 involved in this embodiment includes a hook component 20, which is configured to be able to move between a storage position in which it is tilted toward the side of the panel component 1 and stored, and a use position in which it is erected from the side of the panel component 1 and used. The hook component 20 includes: a claw portion 24, which is locked to the panel component 1 when a first load is applied to the hook component 20 in a direction further erected from the use position; and a fragile portion 26, which is deformed in a manner to break free from the locking of the claw portion 24 on the panel component 1 when a second load exceeding the first load is applied to the hook component 20 in the use position.

[0044] According to the above configuration, when an overload is applied to the hook member 20 , an excessive load is not applied to the front edge portion 1 d , thereby preventing the claw portion 24 or the panel member 1 from being damaged, for example.

[0045] Furthermore, in the vehicle hook device 10 according to the present embodiment, the thickness of the fragile portion 26 is thinner than the thickness of the peripheral portion of the fragile portion 26. Thus, the fragile portion 26 can be formed with a simple structure.

[0046] Furthermore, in the vehicle hook device 10 according to this embodiment, the hook member 20 has an abutment portion 28. When a load is applied in the direction of falling from the stored position, the abutment portion 28 abuts against the front end portion of the rear side wall 1g of the opening 1c of the panel member 1 to prevent the hook member 20 from falling off the panel member 1. This prevents the hook member 20 from moving in the falling direction, thereby preventing erroneous operation.

[0047] Furthermore, in the vehicle hook device 10 according to this embodiment, when a load in the falling direction is applied to the hook member 20 in the stored position, the fragile portion 26 is held by the rear side wall 1g without deforming. Thus, when a load in the falling direction is applied to the hook member 20 from the stored position, the fragile portion 26 is held without deforming, thereby maintaining the contact portion 28 in contact with the front end of the rear side wall 1g. Furthermore, movement of the hook member 20 in the falling direction is prevented, thereby preventing malfunction.

[0048] Furthermore, in the vehicle hook device 10 according to this embodiment, the fragile portion 26 and the contact portion 28 are formed on the same member, namely the leg portion 22. This allows the movable range of the hook member 20 to be expanded compared to a case where the fragile portion 26 and the contact portion 28 are formed on separate members.

[0049] The hook member 20 also includes a fitting portion 32 having a pair of clamping pieces 32a. When the hook member 20 is assembled to the panel member 1, the fitting portion 32 can be fitted into the rotating shaft 2 by pressing the pair of clamping pieces 32a with a predetermined force perpendicular to the axis of the rotating shaft 2. This structure improves the assembly workability of the vehicle hook device 10. Furthermore, even if the hook member 20 becomes dislodged from the rotating shaft 2 due to excessive load, the hook member 20 can be easily assembled to the panel member 1.

[0050] Furthermore, in the vehicle hook device 10 according to this embodiment, the claw portion 24 and the contact portion 28 are provided on opposite sides of each other. This effectively secures the hook member 20 in the use position according to the movement of the hook member 20 and effectively prevents the hook member 20 from falling off in the stored position.

[0051] In this embodiment, the front edge 1 d of the opening 1 c of the panel member 1 is shown as the object to be engaged by the claw portion 24 . However, the present invention is not limited thereto, and any component that receives the load applied to the hook member 20 may be used.

[0052] Furthermore, in this embodiment, the hook member 20 is shown as being composed of a plurality of parts (the interior hook 20A and the exterior hook 20B), but the present invention is not limited thereto. For example, the hook member 20 may be a single part.

[0053] Furthermore, in this embodiment, the panel component 1 is shown to have a rotating shaft 2 and the hook component 20 is supported so as to be able to rotate around the rotating shaft 2, but the present invention is not limited to this. For example, it can also be the following method: the panel component 1 is installed with a shell, the shell has a rotating shaft 2, and the hook component 20 is supported so as to be able to rotate around the rotating shaft 2.

[0054] Furthermore, the above embodiments are merely specific examples for implementing the present invention, and the technical scope of the present invention should not be interpreted as being limited by them. That is, the present invention can be implemented in various forms without departing from its gist or main features.
