[Effects of the Invention]
[0010] According to the present invention, it is possible to prevent damage to a predetermined component that receives the load applied to the hook member. [Brief explanation of the drawing]
[0011] [Figure 1] Figure 1 is a schematic diagram showing a vehicle hook device according to an embodiment of the present invention. [Figure 2] Figure 2 is a view from arrow II in Figure 1. [Figure 3] Figure 3 is a schematic diagram showing a vehicle hook device when the hook member is in the position for use. [Figure 4] Figure 4 illustrates the effect of the load applied to the hook member. [Modes for carrying out the invention]
[0012] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 is a schematic diagram showing a vehicle hook device according to an embodiment of the present invention. Figure 1 shows the X, Y, and Z axes. In Figure 1, the left-right direction is referred to as the front-rear direction or X direction, the left direction as the front direction, front side, or "+X direction", and the right direction as the rear direction, rear side, or "-X direction". The up-down direction is referred to as the vehicle height direction, interior-interior-exterior direction, or Y direction, the upward direction as the interior side of the vehicle or "+Y direction", and the downward direction as the exterior side of the vehicle or "-Y direction". The depth direction is referred to as the vehicle width direction or Z direction. In Figure 1, the direction in which the hook member 20 (described later) is raised is referred to as the clockwise direction or "upright direction", and is denoted as "CW1". The direction in which the hook member 20 is lowered is referred to as the counterclockwise direction or "lowered direction", and is denoted as "CW2".
[0013] Figure 1 shows a panel member 1 that constitutes the interior material of the vehicle's interior. The vehicle hook device 10 according to this embodiment is attached to the panel member 1.
[0014] The panel member 1 has a surface 1a facing the interior side of the vehicle (+Y direction), a recessed storage section 1b formed to recess from the surface 1a toward the exterior side of the vehicle (-Y direction), and an opening 1c. The opening 1c is located in the center of the storage section 1b and connects the interior side of the vehicle with the exterior side. The front edge 1d of the opening 1c has a front wall 1f extending toward the exterior side of the vehicle. The rear edge 1e of the opening 1c has a rear wall 1g extending toward the exterior side of the vehicle.
[0015] Panel member 1 has a cylindrical shaft 2. The shaft 2 extends in the vehicle width direction (Z direction).
[0016] The vehicle hook device 10 according to this embodiment includes the hook member 20 described above. The hook member 20 has an interior hook 20A positioned on the interior side (+Y direction) and an exterior hook 20B positioned on the exterior side (-Y direction).
[0017] Figure 2 is a view taken in the direction of arrow II in Figure 1. As shown in Figure 2, the hook member 20 is stored in the storage portion 1b. The in-vehicle-side hook 20A and the out-of-vehicle-side hook 20B are combined with each other. The in-vehicle-side hook 20A has a pair of flanges 31 disposed on both sides in the vehicle width direction (Z direction) and extending in the front-rear direction (X direction). The out-of-vehicle-side hook 20B is fitted between the pair of flanges 31. The storage portion 1b has both side walls 1j disposed on both sides in the vehicle width direction (Z direction) and extending in the front-rear direction. The shaft 2 shown by a dashed line in Figure 2 projects from each of the both side walls 1j toward the pair of flanges 31.
[0018] As shown in Figures 1 and 2, the in-vehicle-side hook 20A has a fitting portion 32. The fitting portion 32 is formed on the flange 31 and is fitted rotatably around the shaft 2. The fitting portion 32 has a pair of clamping pieces 32a. Each of the pair of clamping pieces 32a has elasticity, is disposed opposite to each other with the shaft 2 therebetween, and clamps the shaft 2. When assembling the hook member 20 to the panel member 1, the pair of clamping pieces 32a are pushed into the shaft 2 side with a predetermined force from a direction orthogonal to the axis of the shaft 2. As a result, the interval between the pair of clamping pieces 32a expands to be greater than or equal to the diameter of the shaft 2, and then the pair of clamping pieces 32a close to clamp the shaft 2, and the fitting portion 32 is fitted to the shaft 2. Thereby, the hook member 20 can be easily assembled to the panel member 1. Conversely, when a force (pulling force) that expands the interval between the pair of clamping pieces 32a to be greater than or equal to the diameter of the shaft 2 is applied to the fitting portion 32 against the elastic force of the pair of clamping pieces 32a, the fitting portion 32 comes off from the shaft 2. Thereby, the hook member 20 comes off from the panel member 1.
[0019] FIG. 3 is a diagram schematically showing the vehicle hook device 10 when the hook member 20 is in the use position. In FIG. 3, the hook member 20 in the storage position is shown by a dashed line, and the hook member 20 in the use position is shown by a solid line. The hook member 20 is supported by a shaft 2 so as to be displaceable between a storage position (the position shown in FIG. 1) and a use position (the position shown in FIG. 3). In the storage position, the hook member 20 is tilted in the counterclockwise direction CW2 on the side of the panel member 1 and stored in the storage portion 1b. Further, the hook member 20 is caused in the clockwise direction CW1 from the side of the storage portion 1b and displaced to the use position. In the use position, it becomes possible to hook an object on the hook member 20. At that time, the load applied to the hook member 20 becomes a force that rotates the hook member 20 in the clockwise direction CW1 (upright direction).
[0020] The outside-vehicle-body hook 20B has a leg portion 22. The leg portion 22 extends from the inside of the vehicle compartment (+Y direction) through the opening 1c to the outside of the vehicle compartment (-Y direction). Hereinafter, in the description of the leg portion 22, the inside of the vehicle compartment may be referred to as the "base end side" and the outside of the vehicle compartment may be referred to as the "tip end side".
[0021] A claw portion 24 is disposed on the front edge 22a of the leg portion 22. The claw portion 24 corresponds to the "locking portion" of the present invention. The claw portion 24 is a convex portion that protrudes in the forward direction (+X direction). When a load is applied to the hook member 20 in the use position, the claw portion 24 locks to the front edge 1d of the opening 1c so that the hook member 20 is not caused from the use position. A groove having the same cross-sectional shape as the V-shaped cross-sectional shape of the tip of the claw portion 24 is formed in the front edge 1d. By the claw portion 24 locking to the front edge 1d, rotation of the hook member 20 in the clockwise direction CW1 (upright direction) is prevented, so that an allowable load can be applied to the hook member 20. The allowable load corresponds to the "first load" of the present invention.
[0022] By the way, when a load exceeding the allowable load is applied to the hook member 20, and an excessive load is applied to the claw portion 24 or the front edge 1d, there is a risk that the claw portion 24 or the front edge 1d or the like is damaged. As a result, it becomes possible to prevent damage to the panel member 1.
[0023] Therefore, in this embodiment, the exterior hook 20B is provided with a weak portion 26. When an overload (corresponding to the "second load" of the present invention) is applied to the hook member 20, the weak portion 26 deforms to release the locking of the claw portion 24 against the front edge 1d. Specifically, the weak portion 26 is located on the interior side (base end side) of the leg portion 22 than the position where the claw portion 24 is located. By recessing the weak portion 26 in the rear edge 22b of the leg portion 22, the weak portion 26 is thinner than the thickness of the surrounding area of the weak portion 26. In other words, the base end side and the tip end side of the weak portion 26 on the leg portion 22 are thicker than the weak portion 26.
[0024] Incidentally, when the hook member 20 is in the storage position shown in Figure 1, a load (corresponding to the "third load" of the present invention) may be applied to the hook member 20 in a counterclockwise direction CW2 (downward tilting direction) from the storage position due to, for example, an incorrect operation such as lifting the rear end of the hook member 20 upward in Figure 1. In this case, if there is nothing to prevent the displacement of the hook member 20 in the counterclockwise direction CW2, the shaft 2 may slip out from between the pair of clamping pieces 32a, and the hook member 20 may fall off the panel member 1.
[0025] Therefore, in this embodiment, the exterior hook 20B of the vehicle interior is provided with a contact portion 28. The contact portion 28 corresponds to the "anti-detachment portion" of the present invention. When a load is applied to the hook member 20 in a counterclockwise direction CW2 (downward tilting direction) from the storage position, the contact portion 28 abuts against the tip of the rear side wall 1g of the opening 1c to prevent the hook member 20 from being displaced in the counterclockwise direction CW2. The contact portion 28 is positioned on the rear side edge 22b of the leg portion 22 and is a projection that protrudes from the rear side edge 22b in the rearward direction (-X direction). By the contact portion 28 abutting against the tip of the rear side wall 1g, it is possible to prevent the hook member 20 from falling off the panel member 1.
[0026] The contact portion 28 and the weak portion 26 are each formed on the same member (for example, the leg portion 22). Specifically, the contact portion 28 is located on the outside of the vehicle interior (towards the front) than the position where the weak portion 26 is located on the leg portion 22. In other words, the weak portion 26 is located on the inside of the vehicle interior (towards the base) than the contact portion 28. The range of motion of the hook member 20 in the rotational direction is from the position where the claw portion 24 contacts the front edge 1d to the position where the rear edge 22b contacts the rear wall 1g. Therefore, as the number of members passing through the opening 1c increases, the range of motion narrows accordingly. In this embodiment, since the contact portion 28 and the weak portion 26 are each formed on the leg portion 22, which is the same member, the range of motion of the hook member 20 can be widened compared to the case where they are each formed on separate members.
[0027] Furthermore, as shown in Figure 1, since the weak portion 26 is located on the interior side (base end side) of the vehicle compared to the contact portion 28, if a load in the tilting direction is applied to the hook member located in the storage position, the weak portion 26 may deform, and the contact portion 28 may detach from the tip of the rear side wall 1g of the opening 1c.
[0028] Therefore, in this embodiment, a holding part 3 is provided to hold the weak part 26 in place so as not to deform when a load in the tilting direction is applied to the hook member located in the storage position. Specifically, the holding part 3 is the rear side wall 1g of the opening 1c. The rear side wall 1g, which is the holding part 3, is thicker than the weak part 26 and contacts and supports the base end and tip end of the weak part 26 on the leg portion 22, thereby holding the weak part 26. This makes it possible to prevent deformation of the weak part 26. In turn, it makes it possible to prevent the contact portion 28 of the rear side wall 1g of the opening 1c from coming loose from contact with the tip end.
[0029] Next, the effect of the load on the hook member 20 will be explained with reference to Figure 4. As shown in Figure 4, the load on the hook member 20 in the position of use generates a torque T1 in a clockwise direction CW1 that rotates the hook member 20 in the upright direction. In addition, a reaction force R1 is generated at the claw portion 24 that engages with the front edge 1d of the opening 1c in response to the load on the hook member 20, and a reaction force R2 is generated at the portion that abuts against the rear end 1h of the storage portion 1b. The torque T1 in the clockwise direction CW1 generated by the load and the torque T2 in the counterclockwise direction CW2 due to the reaction forces R1 and R2 are balanced. As a result, the hook member 20 is held in the position of use. At this time, no load is applied to the hook member 20 that would widen the gap between the pair of clamping pieces 32a to more than the diameter of the shaft 2.
[0030] On the other hand, if the hook member 20 is overloaded and the weak portion 26 deforms, causing the claw portion 24 to disengage from the front edge 1d, a torque CW1 in a clockwise direction will be generated on the hook member 20 with the rear end portion 1h of the storage portion 1b as the fulcrum. This will cause a force to be applied to the fitting portion 32 that widens the gap between the pair of clamping pieces 32a to more than the diameter of the shaft 2. As a result, the fitting portion 32 will detach from the shaft 2, causing the hook member 20 itself to detach from the panel member 1, thus preventing deformation or damage to the shaft 2, for example.
[0031] The vehicle hook device 10 according to this embodiment includes a hook member 20 that is displaceable between a storage position in which it is folded and stored on the side of the panel member 1 and a usage position in which it is pulled up from the side of the panel member 1 and used. The hook member 20 includes a claw portion 24 that engages with the panel member 1 when a first load is applied in a direction that pulls it further up from the usage position, and a fragile portion 26 that deforms to release the claw portion 24 from the panel member 1 when a second load exceeding the first load is applied in the usage position.
[0032] With the above configuration, if an overload is applied to the hook member 20, an excessive load will not be applied to the front edge 1d, thus preventing damage to, for example, the claw portion 24 or the panel member 1.
[0033] Furthermore, in the vehicle hook device 10 according to this embodiment, the weak portion 26 is thinner than the thickness of the surrounding area. This makes it possible to form the weak portion 26 with a simple structure.
[0034] Furthermore, in the vehicle hook device 10 according to this embodiment, the hook member 20 has a contact portion 28 that abuts against the tip of the rear side wall 1g of the opening 1c of the panel member 1, so as to prevent the hook member 20 from falling off the panel member 1 when a load is applied in the direction of tilting from the storage position. This prevents the hook member 20 from being displaced in the direction of tilting, thereby preventing erroneous operation.
[0035] Furthermore, in the vehicle hook device 10 according to this embodiment, the fragile portion 26 is held by the rear wall 1g so as not to deform when a load in the tilting direction is applied to the hook member 20 in the stowed position. As a result, when a load in the tilting direction is applied to the hook member 20 from the stowed position, the fragile portion 26 is held so as not to deform, making it possible to maintain the state of the contact portion 28 that abuts the tip of the rear wall 1g. Consequently, displacement of the hook member 20 in the tilting direction can be prevented, making it possible to prevent erroneous operation.
[0036] Furthermore, in the vehicle hook device 10 according to this embodiment, the fragile portion 26 and the contact portion 28 are each formed on the same member, the leg portion 22. This allows for a wider range of motion of the hook member 20 compared to the case where the fragile portion 26 and the contact portion 28 are each formed on separate members. Furthermore, the hook member 20 has a fitting portion 32, and the fitting portion 32 has a pair of clamping pieces 32a. When assembling the hook member 20 to the panel member 1, the fitting portion 32 can be fitted to the shaft 2 by pushing the pair of clamping pieces 32a toward the shaft 2 with a predetermined force from a direction perpendicular to the axis of the shaft 2. With the above configuration, it is possible to improve the assembly workability of the vehicle hook device 10. In addition, even if the hook member 20 comes off the shaft 2 due to overload, the hook member 20 can be easily assembled to the panel member 1.
[0037] 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 makes it possible to effectively fix the hook member 20 in the usage position and prevent the hook member 20 from falling off in the storage position in accordance with the movement of the hook member 20.
[0038] In this embodiment, the front edge 1d of the opening 1c of the panel member 1 is shown as the object that the claw portion 24 locks onto, but the present invention is not limited to this, and any part that can receive the load applied to the hook member 20 is acceptable.
[0039] Furthermore, although this embodiment shows a hook member 20 composed of multiple parts, such as an interior hook 20A and an exterior hook 20B, the present invention is not limited to this, and for example, the hook member 20 may be a single part.
[0040] Furthermore, in this embodiment, the panel member 1 is shown to have a shaft 2 and the hook member 20 is rotatably supported around the shaft 2. However, the present invention is not limited to this, and for example, a case may be attached to the panel member 1, the case may have a shaft 2, and the hook member 20 may be rotatably supported around the shaft 2.
[0041] Furthermore, the above embodiments are merely examples of how the present invention may be implemented, and the technical scope of the present invention should not be limited by them. In other words, the present invention can be implemented in various ways without departing from its gist or its main features. [Industrial applicability]
