[0003] International Publication No. 2017-090415

[0004] In the technology disclosed in Patent Document 1, only the center of the bracket is fixed by the bolt, so depending on the direction of the load input to the hook, the hook device tends to rotate along the mounting surface with the bolt as the rotation fulcrum. In this case, it is possible for the positioning pin to abut against the edge of the hole in the vehicle body panel, but improvement in load resistance is desired.

[0005] An object of the present invention is to provide a technique for reliably preventing a hook device from rotating along the surface to which it is attached even if an excessive load is applied when the hook is used.

[0006] To solve the above problems, one aspect of the present invention is a hook device that is fixed to a workpiece, and includes a bracket made of a metal material that is placed on the workpiece, a hook that is rotatably supported on the bracket, and a base made of a resin material that is placed on the bracket. The base has a bottom located on the front side of the bracket and a pin that protrudes from the bottom to the back side and is inserted into an insertion hole in the workpiece. The bracket has a protrusion that protrudes to the back side and is inserted into an insertion hole in the workpiece that is formed in the insertion hole or in a position separate from the insertion hole.

[0007] According to the present invention, it is possible to provide a technique for reliably preventing the hook device from rotating along the surface to which it is attached even if an excessive load is applied when the hook is used.

[0009] Fig. 1 is a perspective view of a hook device 10 according to an embodiment. Fig. 1(a) is a view of the hook device 10 as seen from the front side, and Fig. 1(b) is a view of the hook device 10 as seen from the back side. Fig. 2 is a perspective view of the hook device 10 secured to a workpiece 24. The hook device 10 shown in Fig. 1 is in its shipping state, before being secured to a mounting hole in the workpiece 24.

[0010] The mounting member 24 to which the hook device 10 is fixed is a vehicle body panel, but may also be an interior panel forming the vehicle interior. The hook device 10 is disposed on the floor, side wall, or ceiling of the luggage compartment of the vehicle.

[0011] In the shipping state of the hook device 10 shown in Figure 1(a), the lid 30 of the base 12 is in an open state, exposing the spring 16, screw 20, and shaft 22. In the hook device 10 shown in Figure 2, the lid 30 is in a closed state, and the hook 14 is in a housed state. The bottom surface of the hook device 10 is placed on and fixed to the workpiece 24. In the actual installation state, an interior panel is further placed on the workpiece 24, and the sides of the hook device 10 are covered by the interior panel.

[0012] The hook device 10 includes a base 12, a hook 14, a spring 16, a bracket 18, a screw 20, and a shaft 22. The base 12 is formed from a resin material and covers the spring 16, the screw 20, and the shaft 22. The hook 14, the spring 16, the bracket 18, the screw 20, and the shaft 22 are formed from a metal material.

[0013] 3 is an exploded view of the hook device 10. The base 12 has a bottom 26, a flange 27, a side wall 28, a cover 30, a locking claw 32, an assembly seat 34, an insertion hole 36, an operation hole 38, a receiving portion 40, a pin 42, a spring receiving portion 44, a hinge 46, and a notch 48.

[0014] The side wall portion 28 extends from the bottom portion 26 and forms the outer periphery of the base 12. The flange portion 27 is formed to protrude outward from the top of the side wall portion 28. The flange portion 27 hooks onto the edge of the opening in the interior panel.

[0015] The lid 30 is rotatably connected to the side wall 28 by a thin hinge 46. A locking claw 32 is formed on each side of the lid 30. The locking claws 32 lock onto the bottom 26 to keep the lid 30 closed as shown in FIG. 2. The hinge 46 is disposed parallel to the shaft 22.

[0016] The assembly base 34 is formed as a protrusion on the bottom portion 26 and supports the spring 16 when the spring 16 is assembled to the shaft 22. When the shaft 22 is inserted into the spring 16, the spring 16 is separated from the assembly base 34. The spring receiving portion 44 hooks onto the first terminal portion 16a of the spring 16 and receives the load from the spring 16.

[0017] The insertion holes 36 are formed in the opposing side wall portions 28 and are arranged coaxially. Both ends of the shaft 22 are inserted into the pair of insertion holes 36. The operation hole 38 is formed in the bottom portion 26 and is configured so that a tool for rotating the screw 20 can be inserted therein.

[0018] The receiving portions 40 are formed as a pair of holes at the base portions of the side wall portions 28. The receiving portions 40 engage with the bracket 18. The notches 48 are formed as a pair of cutouts in the bottom portion 26, and are located below the insertion hole 36, i.e., on the bottom portion 26 side. The notches 48 are formed so that a portion of the bracket 18 can be inserted into them.

[0019] 1(b), the pin portion 42 is formed in a columnar shape protruding from the rear surface of the bottom portion 26. The cross section of the pin portion 42 is formed in a T-shape. The pin portion 42 functions to position the hook device 10 when attaching it to the workpiece 24, and can also withstand a load input to the hook device 10.

[0020] The hook 14 is formed in a generally U-shape and is rotatably supported by the bracket 18. The hook 14 can be formed from a metal plate, making it inexpensive. A bearing portion 50 is formed at each end of the hook 14. The bearing portion 50 has an axial hole portion 52 in the center, into which the shaft 22 can be inserted. The bearing portion 50 has an annular outer peripheral surface and is connected to the main body of the hook 14.

[0021] The radial protrusion 54 protrudes radially outward from the outer circumferential surface of the bearing portion 50. The radial protrusion 54 functions as a stopper that stops the rotation of the hook 14. The radial protrusion 54 also receives the second terminal portion 16b of the spring 16 and receives a load from the spring 16. The bias of the spring 16 maintains the hook 14 in the housed state shown in FIG. 2 .

[0022] The spring 16 is a coil spring that biases the hook 14 in the closing direction. A first terminal portion 16a of the spring 16 abuts against the spring receiving portion 44 of the base 12, and a second terminal portion 16b abuts against the radial protrusion 54 of the hook 14. The spring 16 is assembled in a twisted state and functions as a torsion spring.

[0023] The bracket 18 is formed by cutting and bending a metal plate material and has a bottom portion 56, an upright portion 58, a support hole portion 60, a rotation stop portion 62, a screw fixing hole 64, a protruding portion 66, and a protruding portion 68.

[0024] The upright portions 58 are bent and erected from the bottom portion 56, and are formed as a pair facing each other. A support hole 60 is formed in each of the pair of upright portions 58. The pair of support holes 60 are formed coaxially and support the inserted shaft 22. As a result, the hook 14 is rotatably supported on the bracket 18 via the shaft 22, and the load pulling the hook 14 is input to the bracket 18.

[0025] The rotation stopper 62 is formed to protrude inward from the upright portion 58. When the rotation stopper 62 abuts against the radial protrusion 54 of the hook 14, it stops the rotation of the hook 14 in the opening direction. The screw fixing hole 64 is formed in the bottom portion 56 so that the screw 20 can be inserted therethrough. The screw fixing hole 64 is smaller than the head of the screw 20. The bracket 18 is fixed to the attached member 24 by the screw 20.

[0026] The protruding portions 66 are formed as a pair so as to protrude. The protruding portions 66 are inserted into the receiving portions 40 of the base 12 to join the bracket 18 and the base 12 together.

[0027] The protruding portion 68 is formed between the pair of overhanging portions 66, and protrudes toward the rear side by bending the bottom portion 56. The protruding portion 68 is inserted into the insertion hole of the workpiece 24.

[0028] The shaft 22 is formed in a cylindrical shape and is inserted into the insertion hole 36 of the base 12, the shaft hole portion 52 of the hook 14, and the spring 16. The shaft 22 has a large diameter portion 22a at one end thereof that serves as a retaining portion.

[0029] 4 is a rear view of the hook device 10 of the embodiment. A bracket 18 is disposed on the bottom surface of the rear side of the hook device 10. The base 12 is placed on the bracket 18, with the bottom portion 26 located on the front side of the bracket 18. The screws 20 are inserted into the screw fixing holes 64 of the bracket 18.

[0030] The pin portion 42 of the base 12 and the protrusion 68 of the bracket 18 are closely opposed to each other but do not abut on each other. The rotational axis direction X of the shaft 22 is perpendicular to the opposing direction Y of the pin portion 42 and the protrusion 68. The rotational axis direction X of the shaft 22 is the same as the rotational axis direction of the hook 14. Because the protrusion 68 has higher rigidity than the pin portion 42 and is in close proximity to the pin portion 42, the protrusion 68 can prevent the pin portion 42 from falling over during installation.

[0031] The protrusion 68 is formed to be wide in the opposing direction Y and in a width direction perpendicular to the protrusion direction. This is because the protrusion 68 is formed by bending a metal plate. The width direction in which the protrusion 68 is formed to be wide is parallel to the rotation axis direction X of the hook 14. The protrusion 68 has high rigidity in the width direction of the protrusion 68. When the hook 14 is pulled in either of the rotation axis directions X, the hook device 10 tends to tilt so that one end of the shaft 22 moves up and down. In other words, the hook device 10 tends to rotate around the axis in the opposing direction Y. At this time, the side edges of the protrusion 68 abut against the insertion hole of the attachment workpiece 24, preventing the hook device 10 from tilting.

[0032] The width direction length of the protrusion 68 is greater than that of the pin portion 42. As a result, when the hook device 10 tries to tilt around the axis in the facing direction Y, the protrusion 68 hits the edge of the hole in the workpiece 24 before the pin portion 42 does. This makes it possible to prevent deformation or damage to the pin portion 42, which is made of a resin material.

[0033] 5 is a cross-sectional view of the hook device 10 and the workpiece 24 taken along line AA shown in FIG. 2. The bracket 18 is placed on the workpiece 24, with the base 12 positioned on the front side of the bracket 18.

[0034] The screws 20 are inserted into and screwed into the screw holes 24b of the workpiece 24, thereby fixing the bracket 18 to the workpiece 24. After the screws 20 are tightened, the lid 30 covers the screws 20.

[0035] The pin portion 42 protrudes from the bottom portion 26 to the rear side and is inserted into the insertion hole 24a of the workpiece 24. The protrusion 68 protrudes from the bottom portion 56 to the rear side and is inserted into the insertion hole 24a of the workpiece 24. By inserting the protrusion 68 made of a metal material into the insertion hole 24a, when the hook device 10 tries to tilt, the protrusion 68 hits the edge of the insertion hole 24a, preventing the hook device 10 from tilting. This improves the load-bearing capacity of the hook device 10.

[0036] The pin portion 42 and the protrusion portion 68 are inserted into the same insertion hole 24a formed in the workpiece 24. This makes it possible to reduce the number of holes formed in the workpiece 24, and to prevent a decrease in the rigidity of the workpiece 24. The proximity of the pin portion 42 and the protrusion portion 68 allows the pin portion 42 to provide auxiliary support for the protrusion portion 68. Because the pin portion 42 and the protrusion portion 68 are inserted into the same insertion hole 24a, positioning is easy.

[0037] The pin portion 42 protrudes further back, i.e., downward, than the screw 20. This allows the pin portion 42 to be inserted into the insertion hole 24a before the screw 20, and therefore can function as a positioning device before the screw 20 is tightened.

[0038] The protrusion 68 protrudes further back, i.e., downward, than the pin portion 42. In other words, the pin portion 42 protrudes further downward than the protrusion 68. This reduces the length of the protrusion 68, improving the yield of brackets 18 that form the protrusion 68. Because the pin portion 42 is longer than the protrusion 68, it is easy to first position the pin portion 42 in the insertion hole 24a, and then insert the protrusion 68 into the insertion hole 24a. The protrusion 68 only needs to be long enough to be inserted into the insertion hole 24a of the attached member 24.

[0039] The protrusion 68 is provided at a position farther from the shaft 22 than the screw 20. The pin 42 is provided at a position farther from the screw 20 than the protrusion 68. A soft washer may be inserted into the protrusion 68 and the pin 42 on the back side of the workpiece 24. The washer can prevent foreign matter from entering through the insertion hole 24a.

[0040] The present invention is not limited to the above-described embodiments, and various modifications such as design changes may be made to the embodiments based on the knowledge of those skilled in the art, and such modified embodiments may also be included within the scope of the present invention.

[0041] In the embodiment, the pin 42 and the protrusion 68 are inserted into the same insertion hole 24a, but the present invention is not limited to this and the pin 42 and the protrusion 68 may be inserted into separate insertion holes. In other words, the protrusion 68 is inserted into an insertion hole in the workpiece 24 that is formed at a different position from the insertion hole into which the pin 42 is inserted.

[0042] The present invention relates to a hook device including a bracket made of a metal material and a base made of a resin material.
