In the above hook device, the hook member is retractable so that it can be taken in and out of the case. Therefore, the safety is excellent and the usability is good due to the use of the spring member. However, the following problems arise.
(A) In this structure, it is difficult to reduce the cost because there are many members such as a hook member, a case, a shaft member (and a nut for retaining the shaft member), and a spring member. Since the arc portion and the protrusion of the hook member are exposed in the case, it is difficult to improve the appearance characteristics.
(A) In this structure, since the hook member is pivotally supported on the case by a dedicated shaft member, it is difficult to improve the assembly work as well as increase the number of members. As an example of this measure, a pivot shaft part is formed integrally with the hook member, and the hook member is pivotally supported with respect to the case by fitting the shaft part with the shaft hole on the case side. However, in this case, since the shaft portion is fitted to the shaft hole by the elastic displacement between the hook member and the case, the length of the shaft portion is naturally restricted, and the pivotal support strength of the hook member cannot be sufficiently satisfied. .
An object of the present invention is to eliminate the above-described problems and further improve appearance characteristics, cost reduction, strength characteristics, and the like.

In order to achieve the above object, according to the first aspect of the present invention, the hook member pivotally supports the base end so as to be rotatable with respect to the case, and the front end side protrudes and protrudes from the front opening of the case and is accommodated in the case.

A bearing portion that receives and pivotally supports the shaft portion, and the bearing portion is provided on a shaft support member that is engaged by being inserted into a corresponding portion of the case, and the holding means includes the shaft portion and the shaft portion. It is formed in the opposing part of a shaft support member .
In the above structure, when not in use, the hook member is held at the case storage position by the holding means provided at the opposing portion of the shaft portion and the bearing portion. When used, the hook member is pulled out of the case by a turning operation, and at this time, the holding means is elastically released.

On the other hand, in the invention of claim 4, the hook member pivotally supports the base end side so as to be rotatable with respect to the case, and the front end side protrudes and protrudes from the front opening of the case and is housed in the case. In the hook device that is held via the holding means at least one of the position and the use position protruding out of the case, the hook member has pivot support shaft portions protruding on both side surfaces of the base end. The case is provided on both inner surfaces, and has a shaft hole that fits one of the shaft portions from the axial direction and a notched portion that fits the other shaft portion from the direction intersecting the axial direction. A shaft, a cylindrical portion that forms a hole substantially concentric with the shaft hole with the notch, and a shaft that pivotally supports the corresponding shaft portion by being attached to the inside of the cylindrical portion so that it can be removed. And a support member.
In the above structure, in the assembling work, first, as shown in FIG. 1, the hook member is inserted into the corresponding shaft hole on the case side in the axial direction and fitted into the case, and the other shaft portion is inserted into the case from the state.

The frame portion 10 defines an opening 11 having a size corresponding to the hook member 2, and integrates the mounting portion 13 corresponding to the mounting location side of the center console 35 described above. The attachment portion 13 has a portion with an attachment hole connected to the rear side of the tubular portion 12, together with a portion that is connected to the rear side of the frame portion 10 and is provided with a protruding piece 13 a with an attachment hole. . The opening 11 is penetrated in the front-rear direction, the opening lower width dimension is set larger than the upper opening width, and the whole is formed in a space of a substantially right triangle. A shaft hole 15 and a shaft hole 16 are provided on both inner side surfaces so as to face downward. One shaft hole 15 is formed as a recess as shown in FIG. The other shaft hole 16 has a notch portion 16a in which a part of the hole is defined as shown in FIGS. 1 and 4 and is communicated with the cylindrical hole of the cylindrical portion 12. .

  The cylindrical portion 12 forms a cylindrical hole concentric with the shaft hole 16, and the cylindrical hole is opened by an extension of the cutout portion 16 a on the shaft hole 16 side. Further, the cylindrical portion 12 has opposed lateral ribs 17 and 17 erected on the upper side, and a cutout portion 18 having a predetermined width is provided between the lateral ribs 17 on the distal end side of the tubular portion 12. Is set. Therefore, the notch 18 is provided only on the distal end side of the cylindrical portion 12. Further, nail 19 for pinching or pinching is provided on the inner surface at the front end side of both lateral ribs 17 so as to face each other.

  The hook member 2 includes a base end 20 for attachment and a hook portion 21, and the size and shape can be accommodated with almost no gap except for the upper side and the upper right side of the opening 11 when the hook member 2 is entirely inserted into the opening 11 of the frame portion 10. I am doing. That is, in this structure, the hook member 2 is set to form a finger contact gap on the upper side and the upper right side in a state in which the hook member 2 is housed in the frame portion 10, and is designed so that dust and the like are not easily collected when not in use. ing. Further, the base end 20 is wider than the hook portion 21, the shaft portions 22 and 23 projecting from both sides, the extension shaft portion 24 connected to the shaft portion 23, and the peripheral surface of the extension shaft portion 24. A plurality of protrusions 25, a recess 26 that is thinned from one side toward the other side, and a recess 27 that is thinned upward from the bottom side as shown in FIG. 5. Among these, the extended shaft portion 24 is formed in a columnar shape extending in the same direction as the shaft portion 23. Each protrusion 25 has a semicircular cross section (inclined surface), and is provided at a position that is equally divided around the extension shaft portion 24. On the other hand, the hook portion 21 is erected on one side of the base end 20 (rear side in the case storage position), is folded from the front end side of the standing wall standing up from the base end 20, and is substantially U between the standing wall. A hook of shape is formed. Reference numeral 28 denotes a plurality of ribs provided on the outer surface of the hook portion 21 for preventing slippage.

  As shown in FIGS. 6 and 7, the shaft support member 3 includes a main body portion 30 inserted into the cylindrical portion 12 and a large-diameter flange portion 31 that comes into contact with the end surface of the cylindrical portion 12. It has a cylindrical shape. The main body portion 30 has a cylindrical hole that receives the shaft portion 23 and pivotally supports the shaft portion 23, and a plurality of elastic pieces 32 provided at positions that equally divide the periphery and a location that is close to the flange portion 31. And an engaging projection 35 provided on the surface. Each elastic piece 32 is partitioned and formed through a U-shaped slit 33 provided in the axial direction of the main body 30, and elastically swings in the radial direction with a base end located on the flange 31 side as a fulcrum. It is possible. Each elastic piece 32 is formed such that the outer surface is slightly lower than the outer periphery of the main body 30, and the inner surface forms a convex portion 34 on the tip side. The convex portion 34 has a semicircular cross section, and elastically engages and disengages with the protrusion 25 on the outer periphery of the extended shaft portion 24 in a state where the shaft portion 23 is inserted into the main body portion 30. That is, the convex portion 34 constitutes a holding means together with the protrusion 25, and engages with the corresponding protrusion 25 at least in the storage position where the hook member 2 is accommodated in the case and the use position where the hook member 2 protrudes outside the case. The member can be held in the storage position and the use position. In this structure, a stable holding state can be obtained without rattling by the contact between the semicircular cross section (inclined surface) of the protrusion 34 and the semicircular cross section (inclined surface) of the protrusion 25.

(Assembly) The hook member 2 described above is assembled in a one-touch operation by inserting the shaft support member 3 into the cylindrical portion 12 after being disposed in the frame portion 10. That is, the hook member 2 is put in the case from the back side of the case 1 as shown in FIG. The hook member 2 has one shaft portion 22 fitted into the corresponding shaft hole 15, that is, the shaft portion 22 is fitted into the shaft hole 15 from the axial direction, and the other shaft portion 23 is notched into the corresponding shaft hole 16. It is temporarily assembled to the case 1 by fitting from the opening, that is, by fitting the shaft portion 23 into the shaft hole 16 through the notch portion 16a from the direction intersecting the axial direction. In this temporarily assembled state, the extension shaft portion 24 is disposed in the cylinder of the cylindrical portion 12. Therefore, when the shaft support member 3 is inserted into the case-side tubular portion 12 from the temporarily assembled state, the extension shaft portion 24 and a part of the shaft portion 23 are partly within the body portion 30 of the shaft support member 3. It is inserted and pivoted in a state where it cannot be removed. The shaft supporting member 3 is pressed between the cylindrical portions 12 with the engaging projections 35 engaged with the cutout portions 18, so that the engaging projections 35 elastically move between the claws 19. Passing with a clicking sound, it engages at the same time as passing and is connected so that it cannot be pulled out.

(Operation) FIG. 2A shows a state when the above hook device is not used. In this non-use state, the hook member 2 is housed in the opening 11 of the case side frame portion 10, and the back of the opening 11 is almost invisible except for the upper gap and the upper right gap. That is, in this structure, a finger contact gap is formed on the upper side at the storage position where the hook member 2 is accommodated in the frame portion 10. In this retracted position, the hook member 2 is disposed between the inner peripheral surface of the opening 11 with almost no gap except for the upper and upper right gaps, and the base end 20 is in contact with the lower inner surface of the opening 11. In addition, since the hook portion 21 is gently inclined upward in the opening 11, it is difficult for dust or dust to collect inside, and the appearance characteristics are excellent.

  Further, in the retracted position as shown in FIG. 8A, the hook member 2 has a convex portion 34 with the elastic displacement of the elastic piece 32 of the shaft support member 3 in which the protrusion 25 of the extension shaft portion 24 is fixed to the case side. And is held by the engagement force. Since the elastic piece 32 is not easily restricted by the length or the like because the elastic piece 32 is provided on the shaft support member 3, the holding means can easily set the engagement force arbitrarily, and the hook member 2 is vibrated at the retracted position. Protruding from the opening 11 can be reliably prevented. In the above-described embodiment, when the hook member 2 is held in the retracted position and the use position, the protrusions 34 on the elastic piece side are provided in two opposite positions, and the corresponding protrusions 25 on the extension shaft side are provided. , 25, the protrusion 34 may be provided only at one place (the corresponding protrusion 25 may be provided at two places instead of four places). Normally, the engagement force increases as the number of engagement points increases, but they are arbitrarily set.

  When the hook device described above is used, the finger is applied to the tip of the hook portion 21 from the gap described above, and the hook member 2 is rotated to the outside of the frame portion 10. In this operation, since the hook portion 21 sets a gap for fingering between the upper inner peripheral surface of the opening 11, the front end of the standing wall forming the hook portion 21 while maintaining the appearance design. It is easy to pull it out to the near side by hooking it on. FIG. 2B and FIG. 8B show a state in which the hook member 2 is thus rotated out of the frame portion 10. In this structure, when the hook member 21 is rotated from the retracted position toward the use position with the shaft portions 22 and 23 as fulcrums, the protrusion 25 of the extension shaft portion 24 elastically climbs over the convex portion 34 of the elastic piece 32. The projection 25 is engaged with the convex portion 34 with the swinging displacement of the elastic piece 32 and held at the use position immediately before reaching the final use position. In this structure, in the middle of the retracted position and the used position of the hook member 21, the protrusion 25 elastically climbs over the convex portion 34 of the elastic piece 32, thereby giving a click feeling to the turning operation and high-grade. It is devised to give a feeling.
