  In the coat hook device of the type that stores such a hook member, when the hook member is pushed (pressed and released) while the hook member is stored in the case body, the tip of the trace pin becomes the lock position of the cam groove. When the hook member starts rotating to the open side by the spring force of the torsion spring and the hook member rotates to the use state, the tip of the trace pin advances to the end of the heart-shaped cam groove, and the hook The member stops and becomes in use. Next, when the hook member is pushed and rotated into the case body to be accommodated, the tip of the trace pin relatively advances to the lock position of the heart-shaped cam groove, and the tip of the trace pin is relatively at the lock position. Locked and the hook member is housed.

  As described above, the coat hook device is provided with a holding mechanism that locks and holds the hook member in the storage state when the hook member is pushed into the storage position from the use state. A metal wire trace pin that is movably attached to the case body side by engaging the tip of the metal wire with a cam groove provided on the inner side surface of the base, and a leaf spring that biases the trace pin toward the cam groove side Therefore, the conventional holding mechanism has a problem that the number of parts is large and the assembling workability at the time of manufacture is poor.

  Also, when using the coat hook device, the trace pin of the metal wire slides in contact with the leaf spring, so abnormal noise is likely to occur due to the contact sliding of the metal, and for this reason, fluorine on the surface of the trace pin It was necessary to perform surface treatment such as coating with resin to prevent abnormal noise due to contact sliding between the leaf spring and the trace pin.

  The present invention solves the above-described problem, and can reduce the number of parts of the holding mechanism that holds the hook member in the housed state, and can prevent the generation of abnormal noise without performing the surface treatment of the parts. An object is to provide a coat hook device.

According to the rotation of the cam groove 22 on the peripheral surface 21, it moves to the left and right, and the trace pin 6 is held so as to be able to swing left and right about the shaft portion 6b.

  As shown in FIG. 9, the hook member 2 is provided with a hook portion 24 for applying a coat or the like at the tip, and a shaft hole 25 is formed through the base portion on the opposite side of the hook portion 24, and the pivot 3 is inserted into the shaft hole 25. Configured to insert. Further, as described above, the opening recess 26 is formed on the left end side of the shaft hole 25, the bush 7 is fitted into the opening recess 26, and the pivot 3 is inserted into the bush 7 and the shaft hole 25. In addition, a base circumferential surface 21 is formed on the base of the hook member 2 as a circular circumferential surface around the shaft, that is, the axis of the pivot 3, and the base circumferential surface 21 has a substantially heart-shaped surface. The cam groove 22 is formed in a shape as shown in the developed view of FIG.

  As shown in FIGS. 9 and 12, a spring member (torsion spring) that biases the hook member 2 toward the use state side (side protruding from the inside of the case body) is located in the spring housing recess 23 at the base of the hook member 2. 4 is provided. One end of the spring member 4 is locked to the hook member 2, and the other end is locked to a part of the case main body 1 to urge the hook member 2 toward the side protruding forward from the case main body 1.

A cam-shaped portion C to which the tip pin 6a is sometimes engaged and held is provided, and the tip pin 6a moves in the cam groove 22 when the hook member 2 protruding in use is pushed into the storage chamber 11 in the case body. Then, once the cam shape portion D is advanced to the uppermost portion and the pushing force is released from the hook member 2, the cam shape portion A is returned to the original shape.

  As shown in FIG. 9, the trace pin 6 is formed by bending a metal wire into a substantially U shape, and is formed by protruding a tip pin 6 a at the upper part and a shaft part 6 b at the lower part. The trace pin 6 has its lower shaft portion 6 b inserted into a shaft hole 17 provided at the lower portion of the back surface portion 13 of the case body 1, and the upper end pin 6 a is inserted into the cam groove 22 from the arc-shaped elongated hole 16 of the back surface portion 13. So as to be inserted between the pin pressing portion 14 and the back surface portion 13. Since the trace pin 6 is movably pressed by the synthetic resin pin presser portion 14 toward the back surface portion 13 side, there is no possibility of noise generation, and the surface treatment for coating the surface of the trace pin 6 with a fluororesin is not performed. It becomes unnecessary.

  When assembling the coat hook device having the above configuration at the time of manufacture, as shown in FIGS. 4 and 9, first, the shaft hole 17 provided with the trace pin 6 and the lower shaft portion 6 b at the lower portion of the back surface portion 13 of the case body 1. The tip pin 6a at the top is inserted into the end portion of the arc-shaped long hole 16 in the back surface portion 13, that is, the end position of the arc-shaped long hole 16 at a position away from the pin pressing portion 14, and in this state 4, the trace pin 6 is rotated clockwise with its shaft portion 6 b as a fulcrum, and is inserted between the pin pressing portion 14 and the back surface portion 13, and the tip pin 6 a is connected to the cam of the hook member 2. It is in a state where it can be inserted into the groove 22.

  Next, the hook member 2 is inserted into the storage chamber 11 from the front opening 12 of the case body 1 with the spring member 4 mounted at the axial center position of the spring housing recess 23 of the hook member 2, and the case body 1. With the shaft hole 15 of the hook member 2 and the shaft hole 25 of the hook member 2 aligned on the same axis, the pivot shaft 3 is press-fitted while being inserted into the bush 7 and the shaft hole 25 from the shaft hole 15, and both ends of the pivot shaft 3 are inserted into the case body. 1 is fitted into the shaft hole 17.

  As a result, the hook member 2 is stored at an appropriate position in the storage chamber 11 of the case body 1, and in this state, the tip pin 6 a of the trace pin 6 previously attached to the case body 1 is connected to the base portion of the hook member 2. Engage in the cam groove 22 on the circumferential surface. Since the spring member 4 urges the hook member 2 in a protruding direction, the spring member 4 is inserted into the storage chamber 11 of the case body 1 with the hook member 2 protruded as shown in the lower diagram of FIG. If the pin 6a is engaged with the position of the cam-shaped portion C of the cam groove 22, it can be easily assembled.

  In this state, the hook member 2 can be stored in the case body 1 against the urging force of the spring member 4, and the hook member 2 in the stored state protrudes forward by the spring force of the spring member 4 by a push operation. The hook member 2 generates an appropriate frictional resistance with respect to the case main body 1 and the pivot 3 on the fixed side by the frictional resistance of the rubber-like elastic bush 7, and rotates at a gentle opening / closing speed. It becomes possible.

  The coat hook device having the above-described configuration is fixed by screwing and tightening by inserting a fixing screw into the mounting hole 18 so that the back surface of the case body 1 is fitted into a rectangular opening provided on the side wall of the passenger compartment. . When the hook member 2 is stored in the storage chamber 11 of the case body 1 and the hook member 2 is pushed (pressed and released) as shown in the upper part of FIG. 15, the hook member 2 rotates about the pivot 3. By moving, the tip pin 6a of the trace pin 6 engaged with the cam groove 22 is temporarily moved from the cam shape portion A in the cam groove 22 to the cam shape portion B as shown in the middle stage of FIG. Then, the hook member 2 rotates so as to protrude forward by the urging force to the spring member 4, and at this time, the tip pin 6a of the trace pin 6 descends in the cam groove 22 as shown in FIG. Stop at position C.

  By this operation, the hook member 2 is in a use state in which it protrudes forward from the case body 1 as shown in the lower part of FIG. As described above, when the tip pin 6a moves in the cam groove 22 while the hook member 2 rotates in response to the push operation, the trace pin 6 moves in the arc-shaped elongated hole 16, but the pin presser 14 It can be pressed with a moderately small load and can follow well without rattling.

  When the hook member 2 in use is brought into a non-use state, as shown in FIG. 16, the hook member 2 is held and rotated upward and pushed into the storage chamber 11 of the case body 1. At this time, as the hook member 2 rotates, the tip pin 6a of the trace pin 6 moves from the cam-shaped portion C to D in the cam groove 22 as shown in FIG. 14, and when the hook member 2 is released, The hook member 2 slightly returns due to the urging force of the spring member 4, and the tip pin 6a enters the cam-shaped portion A as shown in the lower part of FIG. 16, and the hook member 2 returns to the initial hook storage state (non-use state).

  Thus, this coat hook device does not require the leaf spring used in the conventional holding mechanism, and the trace pin 6 has an appropriate amount due to the spring elasticity of the pin holding portion 14 provided on the back surface portion of the case body 1. It can be slid by being pressed with a small load. Further, when attaching the trace pin 6, the tip pin 6 a is inserted into the shaft hole 17 with the shaft portion 6 b of the trace pin 6 inserted into the shaft hole 17, and the pin presser portion 14 and the back surface portion 13 are moved away from the pin presser portion 14. The trace pin 6 can be assembled by a simple assembling work that is simply rotated so as to be inserted in between. Further, since the leaf spring used in the conventional holding mechanism is not used, the surface treatment of the trace pin 6 becomes unnecessary, and the generation of abnormal noise that is likely to occur due to sliding with the trace pin 6 during the turning operation of the hook member 2 is generated. Can be prevented.

  In the above-described embodiment, the rubber-like elastic bush 7 is fitted into the shaft hole portion of the hook member 2 to generate a frictional resistance between the hook member 2, the pivot 3, and the case body 1. Although the opening / closing (turning) speed of the motor is moderated, this can also be done using an oil damper.
