[0003] [Patent Document 1] U.S. Patent No. 10,065,565 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional technology, when an object is hung on the hook portion of the hook, the load is transmitted from the hook to the bezel, which may cause defects such as cracks or breakage in the bezel. Therefore, the present invention provides a cargo hook that can improve the load-bearing capacity. [Means for solving the problem]

[0005] To solve the above problems, the cargo hook of the present invention employs the following means.

[0006] That is, the first invention of the present invention is a cargo hook to be installed in the interior of a vehicle, comprising: a hook connected so as to be rotatable around an axis extending horizontally relative to the interior; a bezel consisting of a frame body fixed to the interior and attached around the hook; and a metal abutment stopper connected to the frame of the interior and stopping the rotation of the hook in the deployment direction in which it protrudes from the bezel in the use position, wherein the direction in which the stopper stops the rotation of the hook is the same as the rotation direction in which the hook is pressed around the axis when an object is hung on it in the use position.

[0007] According to the first aspect of the present invention, the load acting on the hook when an object is hung on it is received by the stopper portion that is connected to the frame of the interior and stops the rotation of the hook. This allows the hook to receive a strong load without placing a load on the bezel. As a result, the load-bearing capacity of the cargo hook can be increased.

[0008] The second invention of the present invention is a cargo hook according to the first invention, wherein the hook has a hooking portion that protrudes like a hook from the bezel in the use position, and a blocking portion that forms a surface flush with the bezel in the use position and blocks the inside of the bezel frame.

[0009] According to the second invention, when the hook is deployed to the use position, the inside of the frame of the bezel can be appropriately closed in an attractive manner by the closing portion of the hook that does not apply a load to the bezel.

[0010] The third invention of the present invention is a cargo hook according to the first or second invention, further comprising a spring that urges the hook to rotate in the deployment direction relative to the interior portion, and a rotary damper that damps the rotation of the hook in the deployment direction relative to the interior portion.

[0011] According to the third aspect of the present invention, the spring can hold the hook in an appropriately positioned state without rattling at the use position, and the rotary damper can deploy the hook with good operational quality while appropriately damping the hook to prevent it from gaining too much momentum toward the use position.

[0012] The fourth invention of the present invention is a cargo hook according to the first or second invention, wherein the interior part is an assist grip attached to the rear part of the seat back of a vehicle seat, and the frame is a fastening end of a main frame that is fastened to the rear part of the seat back of the assist grip.

[0013] According to the fourth aspect of the present invention, the luggage hook can be provided in a state that is rational and has good load-bearing capacity by utilizing the mounting structure of the assist grip that is attached to the rear portion of the seat back.

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0016] (First embodiment) First, the configuration of a cargo hook 10 according to a first embodiment of the present invention will be described with reference to Figures 1 to 11. In the following description, when directions such as front, back, up, down, left, and right are indicated, they refer to the respective directions shown in the respective figures. Furthermore, when the term "seat width direction" is used, it refers to the left and right direction of a seat (vehicle seat) 1, which will be described later. Furthermore, in the following description, when no specific reference figure is indicated or when no reference figure has a corresponding symbol, any of Figures 1 to 11 will be referred to as appropriate.

[0017] As shown in Figure 1, the cargo hook 10 according to this embodiment is configured as a so-called convenience hook, which is provided on the rear portion of the seat back 2 of the seat 1 that constitutes the right seat of the automobile. Specifically, the cargo hook 10 is incorporated into the lower left portion of the assist grip 3 that is attached to the rear portion of the seat back 2. Here, the assist grip 3 corresponds to the "interior part" of the present invention.

[0018] As shown in Fig. 2, the cargo hook 10 has a hook 11 with a hook-shaped hook portion 11B, and a bezel 12 that serves as a frame attached around the hook 11. The hook 11 is rotatably connected to the assist grip 3. This allows the hook 11 to be switched between a use position in which the hook portion 11B protrudes rearward from the bezel 12 in the figure, and a storage position (see Fig. 3) in which the hook 11 is stored flush with the bezel 12.

[0019] Specifically, when the user presses the exposed surface of the hook 11 with a finger from the storage position shown in Fig. 3, the hook 11 is biased to deploy to the use position shown in Fig. 2. When the user presses the hook 11 with a finger into the frame of the bezel 12 from the use position shown in Fig. 2, the hook 11 is locked in a non-deployed state at the storage position shown in Fig. 3. By repeating this operation, the hook 11 is alternately switched between the storage position shown in Fig. 3 and the use position shown in Fig. 2.

[0020] As shown in Figure 4, the cargo hook 10 is incorporated inside the assist grip 3. The assist grip 3 has a grip body 3A that serves as the gripping portion, and a main body frame 3B that forms a horizontally elongated skeleton along the grip body 3A. The grip body 3A has a longitudinal center portion that serves as the gripping portion and is curved in an arch shape backward in the figure relative to both end portions. Both longitudinal end portions of the grip body 3A are abutted against the back surface of the seat back 2 from the rear in the figure and fixed thereto.

[0021] Specifically, the grip body 3A is integrally fixed by fastening both longitudinal ends (fastening ends 3C) of the main body frame 3B to the back surface of the seat back 2 from the rear as shown in the figure with bolts B. The cargo hook 10 is connected to a metal bracket 18 that supports the entire unit by fastening it together with the fastening end 3C on the left side of the main body frame 3B as shown in the figure with a bolt B.

[0022] As a result, the luggage hook 10 is configured to have a reasonable and good load-bearing capacity by utilizing the mounting structure in which the assist grip 3 is attached to the rear surface of the seat back 2. Here, the fastening end 3C on the left side of the main frame 3B in the figure to which the bracket 18 is connected corresponds to the "frame" of the present invention.

[0023] The specific configuration of each part of the cargo hook 10 will be described in detail below. As shown in Figs. 5 to 8, the cargo hook 10 is configured to include, in addition to the hook 11, bezel 12, and bracket 18 described above, a base 13, a rotary shaft 14, a rotary damper 15, and a spring 16. The hook 11, bezel 12, and base 13 are made of resin. The bracket 18, rotary shaft 14, and spring 16 are made of metal. The specific types of resin and metal materials are not particularly limited.

[0024] Specifically, the hook 11 is made of glass fiber reinforced plastic (GFRP) and has excellent load-bearing capacity. The hook 11 has a main body 11A rotatably connected to a base 13 by a rotation shaft 14 extending in the seat width direction (horizontal direction). The hook 11 has a hooking portion 11B that juts out from the rear edge of the main body 11A in the illustration and bends back in a hook-like shape toward the upper front side. The hook 11 also has a closing portion 11C that bulges out from the top surface of the main body 11A in the illustration.

[0025] The blocking portion 11C bulges out from the top surface of the main body 11A in the rotational direction to face the hook portion 11B. The blocking portion 11C bulges out upward in a cylindrical shape from the middle of the main body 11A in the rotational direction to the front edge portion shown in the figure. The hook 11 has a protruding portion 11D that protrudes further upward from the front edge portion of the blocking portion 11C shown in the figure.

[0026] As shown in Fig. 9, the rear surfaces of the main body 11A and the hook portion 11B of the hook 11 are flat and extend flush with each other. Specifically, the rear surface of the hook 11 is a vertically elongated, flat rectangle that can be loosely fitted into the frame of the bezel 12. When the hook 11 is pushed into the storage position around the axis of the rotation shaft 14, the rear surface of the hook 11 is flush with the rear surface of the frame portion 12A of the bezel 12, thereby closing the interior of the frame of the bezel 12 from the outside in an attractive manner (see Fig. 3).

[0027] 10, the hook 11 has a shape in which the rear surface of the blocking portion 11C rises flatly upward from the entire upper surface of the main body portion 11A in the seat width direction. When the hook 11 is deployed to the use position around the axis of the rotation shaft 14, the rear surface of the blocking portion 11C forms a surface flush with the rear surface of the frame portion 12A of the bezel 12, thereby closing the interior of the frame of the bezel 12 in an attractive manner. As a result, when the hook 11 is deployed to the use position, the rear surface of the blocking portion 11C closes the interior of the frame of the bezel 12, preventing the contents of the assist grip 3 from being seen from the outside from inside the frame of the bezel 12 (see FIG. 2).

[0028] 10, the hook 11 is deployed to the use position, whereby its protruding portion 11D is pressed against and locked in the rotational direction against an abutting portion 18C of a bracket 18, which will be described later. When an object is hooked on the hooking portion 11B from the state where the hook 11 is deployed to this use position, the hook 11 receives a force that pushes it around in the clockwise direction shown in the figure, i.e., in the direction of further deployment around the axis of the rotation shaft 14, due to the weight of the hooked object.

[0029] However, the load acting on this hook 11 is transmitted to the abutment stop portion 18C of the metal bracket 18, which abuts and stops the rotation of the hook 11 in the deployment direction. As a result, the load acting on the hook 11 is more strongly received by the metal bracket 18, rather than by the resin bezel 12 attached around it.

[0030] When the hook 11 is pushed into the storage position shown in Fig. 9, the front edge portion of the main body 11A shown in the figure is pressed against the latch 17 installed on the base 13 shown in Fig. 6 and engages with the latch 17. As a result, the hook 11 is held in the storage position against the rotational biasing force in the deployment direction of the spring 16 described below.

[0031] When the user pushes the rear surface of the hook 11 forward from the state in which the hook 11 is engaged with and held by the latch 17 at the storage position, the hook 11 is released from the engagement state with the latch 17. As a result, the hook 11 is deployed to the use position by the rotational biasing force in the deployment direction of the spring 16, which will be described later.

[0032] 11, the bezel 12 has a vertically elongated frame portion 12A and arrowhead-shaped fitting claws 12B extending forward from the front edge of each side of the frame portion 12A. The bezel 12 is attached by pushing the frame portion 12A into a fitting hole 3D formed in the grip body 3A of the assist grip 3 from the rear as shown in the figure, so that the frame portion 12A fits along the periphery of the fitting hole 3D.

[0033] Specifically, the bezel 12 is attached integrally by having its frame portion 12A pressed into the fitting hole 3D from the rear as shown in the figure, with the fitting claws 12B snap-fitted into the inner periphery of the fitting hole 3D. As a result, the bezel 12 is attached with its frame portion 12A fitted along the periphery of the fitting hole 3D. As a result, the bezel 12 is provided in a state where it surrounds the hook 11 so that the hook 11 can be rotated between the use position and the storage position inside the frame portion 12A.

[0034] As shown in Fig. 8, the rotary damper 15 is provided by being passed through a rotary shaft 14 that rotatably connects the hook 11 to the base 13. The rotary damper 15 is configured as a viscous damper equipped with a so-called one-way clutch. Specifically, the rotary damper 15 is configured to generate a braking force against the relative rotation between the inner and outer cylindrical portions by the viscous resistance of oil filled between the inner and outer cylindrical portions that are passed through the rotary shaft 14 and that cover the inner cylindrical portion.

[0035] The rotary damper 15 has its inner cylindrical portion fitted integrally with the rotating shaft 14 in the rotational direction, and its outer cylindrical portion engaged integrally with the base 13 in the rotational direction. As a result, when the hook 11 rotates together with the rotating shaft 14 in the deployment direction, the inner cylindrical portion of the rotary damper 15 rotates relative to the outer cylindrical portion, and the rotational speed is suppressed by the viscous resistance of the oil filled inside. As a result, the rotational speed of the hook 11, which is deployed by the rotational biasing force of the spring 16, is appropriately damped, and the hook 11 is deployed with good operational quality.

[0036] When the rotary damper 15 pushes the hook 11 from the use position to the storage position, the viscous resistance of the oil does not act, and the hook 11 can be smoothly pushed into the storage position against the biasing force of the spring 16. The spring 16 is a so-called coil spring 16, and is passed through the rotary shaft 14 together with the rotary damper 15 and is arranged side by side with the rotary damper 15 in the axial direction.

[0037] One end of the spring 16 is hooked onto the main body 11A of the hook 11, and the other end is hooked onto the base 13. As a result, the spring 16 applies a spring force between them so as to constantly urge the hook 11 to rotate relative to the base 13 around the axis of the rotation shaft 14 in the deployment direction.

[0038] As shown in Figures 5 and 6, the bracket 18 is made of a single metal plate that has been bent by pressing. As shown in Figure 4, the bracket 18 is fitted from the rear in the figure to the fastening end 3C on the left side in the figure of the main frame 3B of the assist grip 3, and is provided with a frame fastening portion 18A that is fastened together with the fastening end 3C to the back surface of the seat back 2 by a bolt B. In addition, as shown in Figures 5 and 6, the bracket 18 is provided with a support portion 18B that is integrally assembled to the base 13 that supports the above-mentioned hook 11 and supports the base 13.

[0039] 10, the bracket 18 also includes an abutment stopper 18C that abuts against the protruding portion 11D of the hook 11 to stop the rotation of the hook 11 when the hook 11 is deployed to the use position. The abutment stopper 18C is bent so that its face faces in the front-to-rear direction, and is configured to abut against the protruding portion 11D of the hook 11 in the rotational direction as the hook 11 rotates to the use position, thereby stopping the rotation of the hook 11.

[0040] To summarize the above, the cargo hook 10 according to this embodiment has the following configuration: Note that the reference numerals in parentheses below correspond to the respective components shown in the above embodiment.

[0041] That is, the cargo hook 10 comprises a hook 11 connected to the interior part 3 of the vehicle so as to be rotatable about an axis extending horizontally, a bezel 12 consisting of a frame body fixed to the interior part 3 and attached around the hook 11, and a metal abutment stopper 18C connected to the frame 3C of the interior part 3 to stop the rotation of the hook 11 in the deployment direction protruding from the bezel 12 in the use position. The direction in which the abutment stopper 18C stops the rotation of the hook 11 is the same as the rotation direction in which the hook 11 is pressed about the axis when an object is hung on it in the use position.

[0042] According to the above configuration, the load acting on the hook (11) when an object is hung on it is received by the stopper portion (18C) that is connected to the frame (3C) of the interior part (3) and stops the rotation of the hook (11). This makes it possible to receive a strong load on the hook (11) without placing a load on the bezel (12). As a result, the load-bearing capacity of the cargo hook (10) can be increased.

[0043] Moreover, the hook (11) has a hook portion (11B) that protrudes like a hook from the bezel (12) in the use position, and a closing portion (11C) that is flush with the bezel (12) in the use position and closes the inside of the frame of the bezel (12). According to the above configuration, when the hook (11) is deployed to the use position, the closing portion (11C) of the hook (11), which does not apply a load to the bezel (12), can properly close the inside of the frame of the bezel (12) in an attractive manner.

[0044] The cargo hook (10) further includes a spring (16) that urges the hook (11) to rotate relative to the interior part (3) in the deployment direction, and a rotary damper (15) that damps the rotation of the hook (11) in the deployment direction relative to the interior part (3). According to the above configuration, the spring (16) can keep the hook (11) properly positioned in the use position without rattling. Furthermore, the rotary damper (15) can properly damp the hook (11) to prevent excessive momentum toward the use position, enabling it to be deployed with good operational quality.

[0045] The interior portion (3) is an assist grip (3) attached to the rear portion of the seat back (2) of the vehicle seat (1). The frame (3C) is a fastening end portion (3C) of a main frame (3B) fastened to the rear portion of the seat back (2) of the assist grip (3). According to the above configuration, the luggage hook (10) can be provided in a state that is rational and has good load-bearing capacity by utilizing the mounting structure of the assist grip (3) attached to the rear portion of the seat back (2).

[0046] Other Embodiments Although one embodiment of the present invention has been described above, the present invention can be embodied in various forms in addition to the above embodiment.

[0047] 1. The cargo hook of the present invention may be attached to the back of a vehicle seat, such as an assist grip attached to the rear of the seat back. The cargo hook may also be attached to the side of the seat back or to a piece of equipment other than an assist grip, such as a seat back table attached to the rear of the seat back. The cargo hook may also be attached to an interior part of the vehicle, such as the door trim, instrument panel, or ceiling, in addition to the vehicle seat.

[0048] 2. The metal abutment stopper that stops the rotation of the hook in the deployment direction may be made of a member that is joined to the frame of the interior part, and may be joined to the frame by fastening with a bolt or by a method other than fastening, such as welding or crimping. The abutment stopper may be configured to stop the rotation of the hook in the deployment direction by abutting against the rotation direction in the use position, and the abutment position is not particularly limited.

[0049] For example, the abutment stopper may be configured to stop the rotation of the hook at a position aligned vertically with the center of rotation of the hook, or at a higher or lower position. The abutment stopper may also be configured to stop the rotation of the hook at a position aligned longitudinally with the center of rotation of the hook, or at a position forward or rearward of the center of rotation of the hook. The abutment stopper may also be configured to stop the rotation of the hook by abutting on a portion that protrudes from the side of the hook, in addition to stopping the hook at a position farthest radially from the center of rotation.
