  However, under the conventional hook device, for example, when the decorative trim of the luggage compartment of an automobile is to be replaced, it is necessary to remove the hook device itself from the body panel side. The bolt head must be exposed by opening it outward, but the cover itself is inside the housing with the locking claw provided at the tip of the cover firmly locked in the locking hole on the housing side. Since it is located, both side walls of the housing become an obstacle, and it is difficult to grip both sides of the cover with fingers. For this reason, the work of opening the cover while releasing the lock claw with respect to the lock hole becomes troublesome, and this is a serious problem during maintenance.

  The present invention has been developed in order to effectively solve the problems of such a conventional hook device. The invention according to claim 1 is directed to a housing fixed to a panel with bolts and a hinge means on the housing. A hook device that includes a cover concealed by the bolt head to conceal the bolt head and an annular hook that has a rotating shaft portion and hooks an object, and the front end of the cover is locked to the housing side. The hinge means has a structure in which a plurality of thin-walled pieces and thick-walled pieces are alternately continued, and when the cover is locked to the housing, each thin-walled piece of the hinge means is bent and is interposed between the cover and the housing. When a concave space facing inward is defined and the cover is unlocked from the housing, each thin piece of the hinge means is extended to lift the cover from the housing.

  The invention described in claim 2 is characterized in that, based on claim 1, two thick pieces are connected to the cover and the housing via three thin pieces.

  According to a third aspect of the present invention, on the premise of the second aspect, the thin piece near the cover has a smaller bending strength than the thin piece near the housing.

  The invention according to claim 4 is based on the premise of claims 1 to 3 that when the cover is locked to the housing, the thick-walled piece closest to the housing faces the rotating shaft portion of the annular hook. Features.

  Therefore, in the invention described in claim 1, under the configuration in which the housing and the cover are integrally connected via the hinge means, for example, the tip of the cover is locked to the housing side. Even if each thin piece is bent, the tip of the tool is inserted into the concave space defined between the housing and the cover, and when the cover is forcibly lifted, each thin piece is stretched. The rear end side of the cover continuously provided by the hinge means floats up and becomes easy to grasp, and the state of the cover being locked to the housing can be easily released. Maintainability is improved.

  In the invention according to claim 2, since the two thick pieces are connected to the cover and the housing through the three thin pieces, the concave space is defined as a horizontal V-shape. It becomes easier to insert the tool tip and the like, and the length of the thick piece can be secured to the maximum, so that the dimension between the fulcrum and the power point in the lever principle becomes longer, and the cover can be lifted more easily.

  In the invention according to claim 3, when the cover is locked to the housing, the thin piece closer to the cover is bent less than the thin piece closer to the housing, so that the thin piece closer to the cover is bent in order from the thin piece side. Therefore, it is possible to reliably define the recessed space between the housing and the cover.

  In the invention according to claim 4, when the tool tip or the like is inserted into the concave space with the thick piece closest to the housing facing the rotating shaft portion of the annular hook, Therefore, the rigidity of the fulcrum is increased, and the rear end side of the cover can be easily lifted by efficiently utilizing the lever principle.

  The present invention relates to a housing fixed to a panel with bolts, a cover integrally connected to the housing via hinge means and concealing the bolt head, and an annular shape having a rotating shaft portion for hooking an object. The hinge means has a structure in which a plurality of thin-walled pieces and thick-walled pieces are alternately continued, and the cover is engaged with the housing. When stopping, each thin piece of the hinge means bends to define an inward concave space between the cover and the housing, and when releasing the locking of the cover to the housing, each thin piece of the hinge means extends. Thus, the maintainability is improved by lifting the cover from the housing.

  Hereinafter, the present invention will be described in detail with reference to a preferred embodiment shown in the drawings. A hook device according to the embodiment is fixed to a vehicle body panel constituting a luggage room of an automobile with bolts 6 as shown in FIG. A box-shaped housing 1, a cover 2 that is integrally connected to one end edge of the housing 1 via a hinge means 3 to be described later and conceals the head of the bolt 6, and is housed in the housing 1 and has the following annular shape The hook 5 has the inverted U-shaped bearing bracket 4 that rotatably supports the pivot shaft portion 5a, and the pivot shaft portion 5a supported by the bearing bracket 4. And an annular hook 5 for hooking.

  The cover 2 is provided with a pair of locking claws 7a and 7b that are paired with each other at the front end and the middle of the opening edge, and the housing 1 has a corresponding portion at the bottom. When the cover 2 is folded inward of the housing 1 through the hinge means 3, the locking holes 8a and 8b having a paired relationship for individually locking the lock claws 7a and 7b are respectively drilled. The lock claws 7a and 7b are locked in the corresponding locking holes 8a and 8b, so that the head of the bolt 6 that fixes the housing 1 to the vehicle body panel together with the bearing fitting 4 can be concealed. 2 is forcibly opened in the outward direction, the lock pawls 7a and 7b are configured to be unlocked with respect to the lock holes 8a and 8b. The locking force of the locking claw 7a with respect to the locking hole 8a is intermediate. It is set to be larger than the locking force for locking claw 7b of the locking hole 8b.

  The hinge means 3 for connecting the one end edge of the housing 1 and the rear end edge of the cover 2 includes three extremely short thin pieces 9a, 9b, 9c that can be deformed as shown in FIGS. Two relatively long non-deformable thick-walled pieces 10a and 10b are alternately and continuously formed between the housing 1 and the cover 2 with a V-shape. When the claws 7a and 7b are locked in the locking holes 8a and 8b, the thin-walled pieces 9a, 9b, and 9c are bent so that the horizontal V-shape is directed inwardly between the rear edge of the cover 2 and one edge of the housing 1. When the lock claw 7a, 7b is unlocked with respect to the locking holes 8a, 8b, a tool tip or the like is inserted into the concave space 11 to force the cover 2 By lifting, each thin piece 9a, 9b, 9c extends. Has a configuration which can float the rear end side of the cover 2 from the housing 1.

  In addition, in this case, since the concave space 11 is defined as a horizontal V shape, it is easy to insert the tool tip and the like, and the maximum length of the thick pieces 10a and 10b can be secured. The dimension between the fulcrum and the power point in the principle becomes longer.

  In this embodiment, the lock claws 7a and 7b are arranged so that the thin piece 9a near the cover 2 is less bent than the thin piece 9c near the housing 1. Are locked in order from the thin piece 9 a side near the cover 2, so that the recessed space 11 can be reliably defined between the housing 1 and the cover 2. The bending strength is adjusted by changing the width and thickness of the thin-walled pieces 9a, 9b and 9c.

  Further, when the locking claws 7a and 7b are locked in the locking holes 8a and 8b, the thick metal piece 10b connected to one end edge of the housing 1 supports the rotating shaft portion 5a of the annular hook 5. When the tool tip or the like is inserted into the above-described concave space 11 because of direct contact with the surface of the tool or facing each other with a certain interval, the tool tip is inserted into the thick piece 10b and the bearing bracket. 4, the fulcrum rigidity is increased, and the cover 2 can be easily lifted by efficiently utilizing the lever principle.

  Therefore, when the hook device having such a configuration is attached to the luggage room of an automobile, the shaft 5a of the annular hook 5 is rotatably supported by the bearing bracket 4 as shown in FIG. When the housing 1 is fixed to the vehicle body panel P together with the bearing bracket 4 with the bolts 6 while being housed in the housing 1, the cover 2 is folded inward of the housing 1 via the hinge means 3, and the cover 1 Since the lock claws 7a and 7b provided on the second side are engaged with the corresponding engagement holes 8a and 8b on the housing 1, the head of the bolt 6 is concealed by the cover 2 as shown in FIG. It will be attached to the wall surface of the luggage room. In the figure, T is a decorative trim.

  In particular, when the cover 2 is folded inward of the housing 1 at this time, the folding strength of the thin piece 9a near the cover 2 is the highest when the cover 2 is folded inward from the above-described molding state. Since it is small, the thin piece 9a is deformed faster than the thin pieces 9b and 9c, and the original V-shape of the hinge means 3 is maintained substantially as shown in FIG. Rotate 90 ° or more. When the cover 2 is further rotated, as shown in FIG. 6B, the intermediate thin piece 9b starts to deform, and the thick piece 10a near the cover 2 becomes substantially parallel to the housing 1. Thereafter, in order to lock the lock claws 7a and 7b in the locking holes 8a and 8b, the cover 2 is pushed out in the direction of the arrow as shown in FIG. 6C. Since the piece 9c starts to deform and the intermediate thin piece 9b enters inside, the horizontal V-shaped concave space 11 is automatically defined.

  Accordingly, as shown by a chain line in FIG. 5, when the annular hook 5 is raised from the housing 1, it becomes possible to hook a hook or a shopping bag on the annular hook 5, and when not in use, If the annular hook 5 is tilted to the housing 1 side, the annular hook 5 does not get in the way.

  Then, in this embodiment, when the hook device itself is removed from the vehicle body panel P side because the decoration trim T of the luggage room of the automobile needs to be replaced, as shown in FIG. When a tool tip 12 such as a screwdriver is inserted into a horizontal V-shaped concave space 11 defined between the rear edge of the cover 2 and the cover 2 is forcibly lifted using the principle of leverage As shown in FIG. 8, the rear end of the cover 2 connected by the hinge means 3 with the thin-walled pieces 9 a, 9 b, and 9 c extending while widening the connecting angle of the two thick-walled pieces 10 a, 10 b. Since the part side is lifted, both sides of the cover 2 are extremely easy to grip as compared with the conventional one. At this time, the lock claw 7b provided in the intermediate portion of the cover 2 is disengaged from the corresponding locking hole 8b of the housing 1.

  Therefore, this time, although not specifically shown, if the both sides of the rear end portion of the cover 2 that has been lifted are grasped with fingers and opened outward while causing the annular hook 5, it is provided at the front end portion of the cover 2. Since the lock pawls 7a can be easily removed from the corresponding locking holes 8a on the housing 1 side, the head of the bolt 6 can be exposed. Therefore, after that, if the bolt 6 is rotated and the hook device itself is removed from the vehicle body panel P, the decorative trim T can be replaced. The maintainability is improved.

  Incidentally, regarding the rotation restriction when the annular hook 5 is used, as shown in FIG. 9, a substantially isosceles triangular stopper protrusion 13 is integrally provided on the back side of the rotation shaft portion 5a so as to form an annular shape. In the state where the hook 5 is tilted to the housing 1 side, the stopper protrusion 13 is placed in contact with one side wall defining the inverted U-shape of the bearing fitting 4 as shown in FIG. At this time, as shown in B of the figure, this time, by causing the stopper projection 13 to collide with the other side wall defining the inverted U-shape of the bearing bracket 4 in conjunction with the rotation of the rotating shaft portion 5a. The rotation position of the annular hook 5 is restricted. Particularly in this case, in the present embodiment, the collision between the metals with the bearing fitting 4 is made because the annular hook 5 itself including the stopper protrusion 13 and the rotating shaft portion 5a is formed by aluminum die casting. Therefore, a large load can be received by the annular hook 5. Further, if the apex angle of the stopper projection 13 is appropriately changed, the rotational position of the annular hook 5 can be freely adjusted.

  Since the cover locked on the housing side can be easily opened, the hook device according to the present invention is very convenient when used in a place where maintenance is required.
