  Incidentally, the hook device is required to improve the tensile strength of the hook. For example, a tensile strength that can withstand a load of several thousand newtons is desired. In order to withstand such strength, the hook must be made of metal. For example, although the hook described in Patent Document 3 is made of metal, its cross section is circular. Therefore, a gap is formed between the case and the case that accommodates the hook, and a lid that closes the gap is used, which increases costs.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a hook device that increases the tensile strength of the hook and reduces the manufacturing cost.

  In order to solve the above-described problems, a hook device according to an aspect of the present invention is formed by punching and bending a metal plate, and has a hook having a hook-side bearing portion and a base-side bearing portion, A base that can accommodate the hook, and a shaft that is inserted through the hook-side bearing portion and the base-side bearing portion and rotatably supports the hook on the base. In this hook device, the thickness of the hook is smaller than the width of the hook.

  According to this aspect, since the hook can be processed and formed from the metal plate, the manufacturing cost can be suppressed while increasing the tensile strength of the hook. Compared with the case where the plate thickness dimension is larger than the plate width dimension in the punching process, it can be easily punched with a small load. Moreover, since it can shape | mold by bending, since bending is performed in the plate | board thickness direction thinner than plate | board width, compared with the case where plate | board thickness dimension is larger than plate | board width dimension, it can be bent easily with a small load.

  According to the present invention, in the hook device, the manufacturing cost can be suppressed while increasing the tensile strength of the hook.

  The case 60 is made of resin and includes a main body 62, a flange 64, a case side bearing 66, a cover 72, a hinge 78, an engagement claw 80, a first elastic part 84, and a second elastic part 82.

  The main body 62 is formed in a box shape, and a flange 64 is formed at the upper end of the main body 62. A mounting hole 70 for inserting a bolt for fixing to the vehicle body is formed in the bottom surface 62a of the main body 62. A pair of shaft holes 68 for inserting the shaft 30 is formed on the long side surface of the main body 62. As shown in FIG. 4B, the case side bearing portion 66 is arranged in the center between the pair of shaft holes 68. The case side bearing portion 66 is formed in a cylindrical shape that is continuous in the axial direction. The case side bearing portion 66 is supported by a pair of wall portions 88. A hook base 63 that restricts the rotation of the hook 20 in the closing direction is provided inside the main body 62.

  As shown in FIG. 3C, the wall portion 88 is connected to the bottom surface 62a and the side portion 62b, is formed so as to protrude in a rib shape, and is arranged so as to face each other. As shown in FIG. 4C, engaging claws 80 are formed at the upper ends of the wall portions 88, respectively.

  As shown in FIG.3 (c), the 1st elastic part 84 is each provided in the outer side of a pair of wall part 88 so that it may extend in an up-down direction. One end of the first elastic portion 84 is connected to the side portion 62 b on the near side of the main body portion 62, and the other end is connected to the bottom surface 62 a of the main body portion 62. The first elastic portion 84 is formed in a stepped shape, and the stepped portion projects from the side portion 62b on the near side of the main body portion 62 toward the vicinity of the shaft.

  A second elastic portion 82 is provided inside the wall portion 88 sandwiched between the pair of wall portions 88. One end of the second elastic portion 82 is connected to the front side portion 62 b and the other end is connected to the bottom surface 62 a of the main body portion 62. The second elastic portion 82 is formed so as to protrude from the side portion 62 b toward the inside of the case 60. The second elastic portion 82 is disposed between the hinge portion 78 and the case side bearing portion 66. As a result, the hook device 10 can be made compact by accommodating the configuration for urging the cover portion 72 between the hinge portion 78 and the case-side bearing portion 66.

  The cover portion 72 is formed in a plate shape, and is pivotally connected to the upper end portion of the main body portion 62 on the opening side of the hook 20 by a hinge portion 78. The hinge portion 78 is formed to be thin and connects the cover portion 72 to the side portion 62 b on the near side of the main body portion 62.

  FIG. 5 is an explanatory diagram for explaining the hook 20. 5A shows a perspective view of the hook 20, FIG. 5B shows a rear view of the hook 20, and FIG. 5C shows a cross-sectional view of the hook 20.

  The hook 20 is formed in a U shape by punching a metal plate having a plate thickness dimension T to form a plate-like primary molded member and then bending and pressing the primary molded member in the plate thickness direction. In addition to the punching process, the primary molded member may be formed using a cutting process or a shearing process. By processing from a metal plate, the strength can be increased as compared to a resin hook, and the processing can be performed at a very low cost compared to the case of producing a hook by die casting. The hook 20 includes a hook side bearing portion 22, an extending portion 24, a connecting portion 26, and an overhang portion 28.

  The pair of hook-side bearing portions 22 have through holes formed at both ends of the hook 20 and are arranged to face each other. The through hole can be easily processed because it punches and processes a metal plate, and can have higher strength than a bearing formed by bending like a hinge. An arc-shaped small diameter portion 27 and an arc-shaped large diameter portion 29 having a diameter larger than that of the small diameter portion 27 are formed around the hook-side bearing portion 22, and the diameter is set so as to connect the small diameter portion 27 and the large diameter portion 29. A projecting portion 28 that projects in the direction is formed. In addition, although the overhang | projection part 28 of embodiment is formed in the level | step difference shape, it is not restricted to this, The protrusion protruded in radial direction may be sufficient. The overhanging portion 28 abuts on the bracket 50 to restrict the rotation of the hook 20 when the hook 20 rotates from the accommodated state to the predetermined rotation angle in the opening direction.

  The pair of extending portions 24 extend from the respective hook side bearing portions 22 and are arranged to face each other in parallel. The connection part 26 connects the extending part 24 which opposes. The connection part 26 is along the axial direction, and functions as an operation part operated by the user when the hook 20 is opened.

  As shown in FIG. 5C, the hook 20 is processed so that the thickness T of the hook is smaller than the width W of the hook. The plate width dimension W of the hook 20 is the dimension of the surface on which the bearing hole is formed, the plate thickness dimension T is the dimension of the surface on which the bearing hole is not formed, the plate thickness dimension of the metal plate and the plate of the primary molded member It is the same as the thickness dimension. In the state where the hook 20 is assembled, the plate thickness dimension T is a dimension in the direction along the side portion 62 b of the case 60, and the plate width dimension is a dimension in the direction along the bottom surface 62 a of the case 60. In addition, although the cross section of the connection part 26 is shown in FIG.5 (c), the extended part 24 also satisfy | fills the same relationship. As a result, a metal plate having a plate thickness dimension T can be punched and processed into a plate-shaped primary molded member having a plate width dimension W. Therefore, compared with the case where the plate thickness dimension T is larger than the plate width dimension W, it can be easily performed with a small load. Can be punched. In addition, since the primary molded member can be formed into a U shape by bending press processing, bending is performed in the thickness direction thinner than the width, and therefore, with a smaller load than when the thickness T is greater than the width W. Can be bent easily.

  FIG. 6A is a perspective view of the bracket 50, and FIG. 6B is a perspective view of the shaft 30. The bracket 50 is formed of metal and is disposed on the outside of the case 60 so as to cover a part of the bottom portion and the side portion of the case 60 that is a resin material, and increases the strength of the hook device 10.

  The bracket 50 includes a pair of bracket-side bearing portions 52, a mounting hole 54 into which a bolt for fixing the hook device 10 to the vehicle body is inserted, and a protruding portion 28 of the hook 20 when the hook 20 is fully opened. And a stopper portion 56 that restricts rotation of the hook 20 in the opening direction. The stopper portion 56 is located at the end on the near side of the bottom surface of the bracket 50.

  The shaft 30 is formed of a metal in a rod shape, and is inserted into the case side bearing portion 66 and the shaft hole 68 of the case 60, the hook side bearing portion 22 of the hook 20, and the bracket side bearing portion 52 of the bracket 50. One end of the shaft 30 may be provided with a flange for retaining, and the other end may be retained by caulking. The shaft 30 rotatably supports the hook 20 on the base 40. The shaft 30 that is separate from each member of the hook device 10 passes through the hole of each member and pivotally supports the hook 20, whereby the strength of the shaft can be increased and the durability load of the hook device 10 can be increased. it can. The hook device 10 shown in FIG.

  FIG. 7 is an explanatory diagram for explaining a state when the hook device 10 is attached to the vehicle body. FIG. 7A is a perspective view of the hook device 10 as viewed from above, and FIG. 7B is a perspective view of the hook device 10 as viewed from below.

  The hook device 10 is delivered with the hook 20 and the cover portion 72 open. When the cover portion 72 is open, the attachment hole 70 at the center of the bottom surface 62a of the case 60 is exposed. Bolts 12 are inserted there and attached to the vehicle body. After the bolt 12 is inserted, the cover portion 72 is closed to the state shown in FIG. Since the bolt 12 is inserted into the mounting hole 54 of the metal bracket 50, it can be firmly fixed to the vehicle body.

  After the bolt 12 is tightened and attached to the vehicle body, the cover portion 72 is closed, so that the space between the hooks 20 is filled with the cover portion 72 and the upper surface of the hook device 10 is flattened as shown in FIG. Therefore, even if the upper surface of the hook device 10 is not covered with a lid, dust or the like is difficult to collect. Moreover, since the upper surface of the hook apparatus 10 is flat, it has an external appearance with good appearance.

  Further, the shaft strength can be increased by fixing the shaft 30 to the metal bracket 50. Here, when a large tensile load is applied to the hook 20 from the rope hung on the hook 20, the U-shaped hook 20 tends to be deformed in a direction in which both ends approach each other. Further, since the shaft 30 receives a load inside the bracket side bearing portion 52, the load is also applied to the central portion of the shaft 30, and the central portion of the shaft 30 is bent and deformed. The part 52 may come off. As shown in FIG. 7A, the cylindrical case-side bearing portion 66 is arranged at the center between the hook-side bearing portions 22. Thereby, the deformation | transformation which both ends of the hook 20 approach is suppressed, the deformation | transformation of the center part of the shaft 30 is suppressed, and possibility that both ends of the shaft 30 will remove | deviate from the bracket side bearing part 52 can be reduced extremely. Further, the axial length of the case side bearing portion 66 is substantially the same as the axial length between the opposing hook side bearing portions 22. That is, the shaft 30 can be covered and held by the case-side bearing portion 66 over almost the entire range between the pair of hook-side bearing portions 22, and deformation of the shaft 30 can be further suppressed.

  FIG. 8 is a cross-sectional view of the hook device 10. 8A is a cross-sectional view taken along line AA of the hook device 10 shown in FIG. 2A, and FIG. 8B is a cross-sectional view taken along line BB of the hook device 10 shown in FIG. It is a cross section.

  When the hook 20 shown in FIG. 8A is not used, the hook 20 and the cover 72 are accommodated so as to be sandwiched between the hooks 20 in the case 60 as shown in FIG. It is arranged substantially parallel to the bottom surface 62a. As shown in FIG. 8A, the protrusion 74 of the cover portion 72 contacts the second elastic portion 82, and the cover portion 72 is urged by the second elastic portion 82 in the opening direction. On the other hand, in a state where the cover portion 72 and the bottom surface 62a are substantially parallel, the engaging claw 80 and the elastic claw body 76 shown in FIG. 4A and FIG. Is restricted from rotating in the opening direction. That is, the biasing in the opening direction of the second elastic portion 82 and the rotation restriction of the engaging claw 80 in the opening direction are balanced, and the cover portion 72 is held in a state substantially parallel to the bottom surface 62a.

  As shown in FIG. 8B, the overhanging portion 28 of the hook 20 is in contact with the step-like first elastic portion 84 so as to be caught from above. That is, the 1st elastic part 84 contacts the overhang | projection part 28 in the accommodation state of the hook 20, and hold | maintains the hook 20 in the accommodation state. The hook 20 is biased in the closing direction by the first elastic portion 84. On the other hand, the hook 20 abuts on the hook base 63 and its rotation in the closing direction is restricted. The hook 20 is held in the closed state by the biasing of the first elastic portion 84 and the restriction of the hook base 63. In addition, when the hook 20 is rotated in the opening direction so that the overhanging portion 28 gets over the first elastic portion 84, that is, when the hook 20 is opened, a click feeling can be transmitted to the user.

  FIG. 9 is an explanatory diagram for explaining the opening operation of the hook 20 in the hook device 10. 9A is a perspective view showing a state in which the cover portion 72 is pushed, and FIG. 9B is a cross-sectional view taken along line EE of the hook device 10 shown in FIG. 9A. FIG. 9 shows a state where the cover 72 is forcibly rotated in the closing direction.

  When the cover part 72 is forcibly rotated in the closing direction, the upper surface of the hook device 10 becomes concave as shown in FIG. Then, the user rotates the accommodated hook 20 in the opening direction and takes it out.

  Here, as shown in FIG. 9B, the inner peripheral surface 26a of the connecting portion 26 is inclined. Specifically, the connecting portion 26 has a lower surface 26c that faces the bottom surface 62a of the case 60 in the accommodated state of the hook 20 and an exposed upper surface 26b on the opposite side. When viewed from the side portion 62b, the upper surface 26b is on the near side relative to the lower surface 26c. That is, the inner peripheral surface 26a of the connecting portion 26 is inclined so as to protrude toward the near side from the lower surface 26c toward the upper surface 26b. Thereby, when a user takes out the hook 20, it can put out easily with a finger | toe on the connection part 26. FIG. FIG. 9B shows an inclination angle 94 formed by a line 90 extending the inner peripheral surface 26 a of the connecting portion 26 and the vertical direction 92. The inclination angle 94 may be set in a range from several degrees to 10 degrees.

  As shown in FIG. 9B, the protrusion 74 and the second elastic portion 82 are in contact with each other, and the cover portion 72 is urged in the opening direction by the second elastic portion 82. Therefore, after the hook 20 is taken out, the cover 72 is returned to the original state, that is, the state parallel to the bottom surface 62a shown in FIG.

  FIG. 10 is an explanatory diagram for explaining a state in which the hook 20 is opened. FIG. 10A is a perspective view of the hook device 10 with the hook 20 in an open state, and FIG. 10B is a cross-sectional view taken along line FF of the hook device 10 of FIG. In FIG. 10, the hook 20 is fully opened.

  When the hook 20 is rotated approximately 90 degrees in the opening direction from the accommodated state, the overhanging portion 28 of the hook 20 comes into contact with the stopper portion 56 of the bracket 50 and the rotation in the opening direction is restricted. When the metal hook 20 is stopped by the resin case 60, the case 60 may be deformed. However, by stopping the metal hook 20 by the metal bracket 50, the rotation of the hook 20 can be stopped more reliably.

  As shown in FIG. 10B, the large diameter portion 29 of the hook 20 is in contact with the first elastic portion 84. Thereby, a frictional force is generated and the open state of the hook 20 can be maintained. Therefore, it is possible to prevent the hook 20 from being rattled due to the vibration of the vehicle or the hook 20 from rotating to the accommodation direction to be in the accommodation state. Further, if the hook 20 is not fully open but is in the open state, the first elastic portion 84 contacts the hook 20 and holds the hook 20 in the open state when the hook 20 is open. Thereby, rattling of the hook 20 in the open state can be suppressed.

  FIG. 11 is an assembly view of a hook device 100 according to a modification. FIG. 12 is a perspective view of a hook device 100 according to a modification. 13 is a cross-sectional view taken along line GG of hook device 100 shown in FIG.

  Similar to the hook device 10 shown in FIG. 1, the hook device 100 according to the modification includes a hook 120, a shaft 30, and a base 140 that can accommodate the hook 120. The base 140 has a bracket 150 and a case 160. The shaft 30 is inserted and assembled in the shaft hole 68 of the case 160 so that the hook side bearing portion 22 of the hook 120 and the bracket side bearing portion 52 of the bracket 150 are aligned. The shaft 30 rotatably supports the hook 120 on the base 140.

  The hook 120 is formed by punching and bending a metal plate, and has hook-side bearing portions 22 that face each other. Details of the hook 120 will be described later. The bracket 150 is made of metal and is disposed outside the case 160.

  The case 160 is made of resin, and has a box-shaped main body portion 162, a flange portion 64 protruding from the upper end of the main body portion 162, a case side bearing portion 166, a mounting hole 70 for fixing to the vehicle body, a cover portion 172, a hinge portion. 178 and a locking claw 179. The case side bearing portion 166 is arranged in the center between the opposing hook side bearing portions 22 and is formed in a cylindrical shape that is continuous in the axial direction. The support portion 188 supports the case side bearing portion 166 and is connected to the bottom surface 62a of the case 160 and the hinge side wall portion 189 on the near side.

  The cover part 172 is formed in a plate shape and is pivotally connected to the upper end of the hinge side wall part 189 of the main body part 162 by the hinge part 178. The shape of the cover part 172 is different from the shape of the cover part 72 of the hook device 10. The cover part 172 is disposed between the hooks 120 in the accommodated state of the hooks 120 and faces the bottom surface 62a of the main body part 162. The hinge part 178 is formed thin, and connects the cover part 172 to the hinge side wall part 189 of the main body part 162. As shown in FIG. 11, the cover portion 172 has a pair of locking claws 179 at the tip.

  The cover portion 172 is in an open state until a hook device 100 is attached to the vehicle body by inserting a bolt into the attachment hole 70. After the cover portion 172 is attached to the vehicle body, the cover portion 172 is closed as shown in FIG. In the arrangement state, the locking claw 179 is locked in the locking hole 169 formed in the bottom surface 62 a of the main body 162. Thereby, it is possible to prevent the cover portion 172 from opening after the hook device 100 is assembled.

  As shown in FIG. 13, the cover portion 172 is bent to the vicinity of the bottom surface 62 a of the main body portion 162 in the closed state. Thereby, when the user takes out the hook 120, the finger can easily enter the lower side of the hook 120. Further, the cover portion 172 is formed with a bent portion 174 formed so as to be recessed toward the bottom surface 62a in the closed state. As shown in FIG. 12, in the closed state, the shape around the bent portion 174 and the hook-side bearing portion 22 of the hook 120 is matched with a curve.

  FIG. 14 is a diagram for explaining the hook 120. 14A is a perspective view of the hook 120, FIG. 14B is a top view of the hook 120, and FIG. 14C is a side view of the hook 120.

  The hook 120 includes a hook side bearing portion 22, an extending portion 124, a connecting portion 26, and an overhang portion 28. The hook 120 is different from the hook 20 shown in FIG. 5A in the shape of the extending portion 124 of the hook 120. An arc-shaped small diameter portion 27 and an arc-shaped large diameter portion 29 having a diameter larger than that of the small diameter portion 27 are formed around the hook-side bearing portion 22, and the diameter is set so as to connect the small diameter portion 27 and the large diameter portion 29. A projecting portion 28 that projects in the direction is formed. The overhanging portion 28 abuts on the bracket 50 to restrict the rotation of the hook 20 when the hook 20 rotates from the accommodated state to the predetermined rotation angle in the opening direction.

  The pair of extending portions 124 extend from the respective hook side bearing portions 22 and are arranged to face each other in parallel. The connection part 26 connects the extending part 24 which opposes. The connection part 26 is along the axial direction, and functions as an operation part operated by the user when the hook 20 is opened. The extending portion 124 is inclined without being bent from the small diameter portion 27 to the connecting portion 26 as compared with the extending portion 24 of FIG. 5A, and the average plate width dimension is increased, so that the rigidity is increased. ing.

  As shown in FIG. 14C, the plate thickness dimension of the hook 120 is smaller than the plate width dimension of the hook 120. As a result, a metal plate having a plate thickness dimension T can be punched and processed into a plate-shaped primary molded member having a plate width dimension W. Therefore, compared with the case where the plate thickness dimension T is larger than the plate width dimension W, it can be easily performed with a small load. Can be punched. In addition, since the primary molded member can be formed into a U shape by bending press processing, bending is performed in the thickness direction thinner than the width, and therefore, with a smaller load than when the thickness T is greater than the width W. Can be bent easily.
