  The present invention relates to a support structure for an openable / closable pocket provided in an interior trim such as a door trim and a rear side trim, and in particular, an openable / removable pocket that can be arbitrarily changed in its pocket volume and can be provided with a simple and inexpensive structure. The present invention relates to a support structure for an openable pocket.

  As a typical example of a conventional openable pocket structure, for example, the one shown in FIG. 12 is known. In the drawing, the door trim 1 has a lower side of a door trim main body 2 formed in a desired curved surface bulges to the indoor side on both sides, and a housing recess 3 that forms a pocket space is formed between the bulging portions 2a and 2b. A pocket cover 4 is rotatably mounted in the recess 3 so that the pocket cover 4 can be tilted forward.

  As shown in FIG. 13, the pocket cover 4 protrudes from the front wall 4 a and the rear side in the substantially orthogonal direction from both sides, and when the pocket cover 4 is tilted to the near side, the side wall 4 b constituting the pocket wall is The shaft hole 4c is opened at the lower end side of the side walls 4b. And the pocket cover 4 is rotatably supported by inserting the hinge pin 4d between this shaft hole 4c and the shaft hole 3b provided in the side wall 3a of the accommodating recess 3 on the door trim main body 2 side. . Further, a guide pin 5 projects from the upper side of the side wall 4 b of the pocket cover 4, and this guide pin 5 is guided in a guide groove 6 provided in the side wall 3 a of the housing recess 3 of the door trim body 2.

  As described above, the openable pocket provided in the conventional door trim 1 is mounted so that the pocket cover 4 can be pivoted to the lower end of the side wall 4b of the pocket cover 4 via the hinge pin 4d in the receiving recess 3 provided in the door trim body 2. The front wall 4a of the pocket cover 4 is tilted toward the front side to open the pocket. At this time, the side wall 4b of the pocket cover 4 constitutes the pocket wall, so that a large opening of the pocket can be secured. The pocket cover 4 is configured to be urged in the closing direction and the opening direction by the spring force of 7, respectively.

  However, in the operation of attaching the pocket cover 4 to the housing recess 3 of the door trim main body 2, it must be assembled in a state in which the spring 7 for applying the spring force is applied, and the assembling operation is troublesome and the spring biasing force. It has been pointed out that the spring 7 is required to act, and the cost increases due to the increase in the number of parts.

  Furthermore, in the above-described openable pocket, the pocket cover 4 can be held only in two positions, ie, when the pocket cover 4 is in the closed state or in the opened state where the pocket cover 4 is tilted to the near side. Thus, the pocket cover 4 cannot be held, and improvement has been desired in terms of usability.

  The present invention has been made in view of such circumstances, and a support structure for an openable / closable pocket that can be opened and closed so that the pocket cover is folded into the front side with the lower end side as a hinge portion in the accommodation recess of the trim body. However, by eliminating the spring, a simple configuration can be realized, the cost can be reduced, and the pocket cover can be held at any position during the opening operation of the pocket cover. An object is to provide a support structure for a pocket.

  In order to achieve the above object, the present invention provides an opening / closing device that is openably / closably mounted so that a pocket cover is folded down toward the front side with a lower end side as a hinge portion in a housing recess of a trim body in an interior trim installed in a vehicle body panel. A ratchet type engagement structure for engaging the guide pin on one side and the guide pin on the other side between the side wall of the pocket cover and the side wall of the receiving recess facing the side wall. The guide pin is engaged at an arbitrary locking point in the ratchet type engaging portion according to the opening / closing operation of the pocket cover, so that the pocket cover can be held at an appropriate open position. To do.

  Here, examples of the interior trim to which the openable pocket is applied include a door trim, a rear side trim, a luggage side trim, and the like. The pocket cover is made of a synthetic resin injection molded body, and when the pocket cover is closed, the front wall that connects to the product surface of the interior trim and forms the product surface, and the left and right sides that protrude from the front wall to the back side. A pair of side walls are formed, and these side walls constitute a pocket wall portion when the pocket cover is brought down to the near side.

  Next, as a support structure of the pocket cover, the lower end of the side wall of the pocket cover is pivotally attached to the accommodating recess side wall of the trim body via a hinge pin, and the front wall of the pocket cover falls down on the front side based on the hinge at the lower end of the side wall. Is pivotally attached to.

  Further, a ratchet mechanism that is simple in structure and can hold the pocket cover in an arbitrary open position is provided between the upper side of the side wall of the pocket cover and the accommodating recess side wall of the trim body. This ratchet mechanism is provided with a ratchet type engaging portion that projects a guide pin on one side between the side wall of the pocket cover and the corresponding side wall of the receiving recess, and engages the guide pin on the other side. It has been. For example, when a guide pin protrudes from the side wall of the trim body housing recess, an arc-shaped ratchet hole is formed in the side wall of the pocket cover, and when the pocket cover is opened and closed, the guide pin moves in the ratchet hole. Therefore, the guide pin is engaged at an arbitrary locking point of the ratchet hole.

  In addition, in order to maintain a balance between the engagement force of the guide pin and the operability to move inside the ratchet hole, a guide pin structure is adopted in which the guide pin is thinned and bent to reduce the pin diameter of the guide pin. Then, the guide pin smoothly moves in the ratchet hole corresponding to the opening / closing operation of the pocket cover. A ratchet groove may be employed instead of the ratchet hole.

  Alternatively, if an opening is opened on at least one of the upper and lower sides of the ratchet hole, when the guide pin passes, the pocket cover opens and closes by bending and deforming so that the width of the ratchet hole is expanded. As a result, the guide pin can be slid smoothly. In this case, the ratchet engaging portion is limited to the ratchet hole.

  On the other hand, when the guide pin is protruded on the side wall of the pocket cover, it is possible to form a ratchet hole on the side wall of the accommodating recess on the trim body side, but in addition to the ratchet hole, a ratchet flange is projected in an arc shape. It can also be set up. In this case, the guide pin can be engaged at an arbitrary position by the ratchet flange being bent in the vertical direction in accordance with the opening / closing operation of the pocket cover. Further, if the guide pins on the pocket cover side are thinned, the guide pins can be smoothly slid in accordance with the opening / closing operation of the pocket cover without imparting flexibility to the ratchet flange.

  As is apparent from the above configuration, the open / close pocket support structure according to the present invention includes a guide pin and a ratchet engagement portion that receives the guide pin between the side wall of the pocket cover and the opposing surface on the trim body side. Because it employs a ratchet mechanism, the conventional spring can be eliminated, and the number of parts can be reduced by eliminating the spring, so that the guide pin can be engaged with the ratchet engagement part on the trim body side. By attaching the hinge of the pocket cover, the assembly of the openable pocket is completed easily.

  Further, according to the ratchet mechanism provided between the side wall of the pocket cover and the side wall of the accommodating recess of the trim body in accordance with the opening / closing operation of the pocket cover, the guide pin is held at an arbitrary point of the ratchet type engaging portion. Therefore, even when the pocket cover is in the middle of opening, the pocket cover can be held at any open position, and the pocket cover can be kept open in a stepwise manner, which is effective for the size of the contained articles. Can be applied.

  As described above, the support structure for the openable pocket according to the present invention is mounted so that the lower end side of the trim cover can be turned into a hinge portion so that the pocket cover can be folded into the housing recess of the trim body. Since a ratchet mechanism comprising a guide pin on one side and a ratchet type engaging portion receiving the guide pin on the other side between the side wall of the pocket cover and the corresponding side wall of the receiving recess is adopted, the trim body side The attachment of the pocket cover to the head has the effect that the conventional spring can be eliminated and the pocket cover can be easily and inexpensively assembled.

  Furthermore, according to the support structure of the openable pocket according to the present invention, a ratchet mechanism including a guide pin and a ratchet type engaging portion is adopted between the upper side of the side wall of the pocket cover and the housing recess side wall facing the pocket cover. Therefore, when opening and closing the pocket cover, the guide pin can be securely held at the latching point of the ratchet type engaging portion at an arbitrary opening position of the pocket cover. Compared to a structure that can be locked only at one position, it can be effectively applied to the size of an article accommodated in a pocket, and has an effect of improving usability and excellent space performance.
