[Patent Document 1]
JP-A-9-142130 [0004]
The air filter mounted in the inside / outside air switching case adsorbs dust and malodorous components and becomes dirty by use. Therefore, it is necessary to take out the air filter from the inside / outside air switching case and replace it during a predetermined maintenance inspection. For this reason, the air filter is configured to be inserted into the case from an insertion opening that can be opened and closed by a lid, and when the air filter becomes dirty, the lid is opened to replace the air filter. Specifically, the inside / outside air switching case and the lid are integrally formed of synthetic resin via an integrally formed hinge, and the lid covers the filter insertion port of the inside / outside air switching case via the integrally formed hinge. And is configured to close.

[Problems to be solved by the invention]
However, in general, an integrally molded hinge made of synthetic resin is closed because a repulsive force is generated by the spring elastic force of the hinge portion in a folded state in which the lid is closed with respect to the insertion opening even if it can be bent. There was a risk that the lid would gradually float by the force and the closed state would be incomplete. Therefore, in order to prevent the lid from lifting, fixing means such as screwing the lid have been studied. However, using another part fixing means leads to an increase in the number of parts, and also during maintenance inspections. When opening the lid, there is a problem that the opening operation becomes complicated.
[0006]
The present invention solves the above-mentioned problems, and even a lid provided with an integrally formed hinge prevents a lift and ensures a good sealing property, and can be easily opened and closed. An object is to provide a mounting structure.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a lid mounting structure according to the present invention is a lid mounting structure in which a lid is integrally molded with a synthetic resin via an integrally molded hinge with respect to a mounting portion. Is formed with three thin bent parts in the transverse direction of the belt-shaped body, and a hinge insertion part is provided in the vicinity of the integrally formed hinge on the attached part side, and the lid is closed to the hinge insertion part. When the integral hinge is folded, a fitting hole is provided to insert a part of the integral hinge. When the lid is closed, the middle bent portion of the three bent portions is folded and the middle The tip of the hinge having the bent portion of the tip is inserted into the hinge insertion portion .
[0008]
Here, when the nail insertion part is provided on the attached part, the nail part is inserted into the nail insertion part when the nail part protrudes from the cover body and the cover body is closed to the attached part side via the integrally formed hinge. It can also be configured to.
[0009]
[Action]
In the lid mounting structure of the above configuration, when the lid is closed with respect to the mounted portion, the integrally formed hinge is folded, but the middle bent portion of the three bent portions is folded in the middle. hinge tip to the bending portion and the distal end is fitted into the hinge fitting part of the mounting portion. As a result, synthetic hinges made of synthetic resin usually generate a repulsive force when they are closed and folded, and the closed lid tends to lift up gradually due to the force, but it is folded as described above. Since the integrated hinge is inserted into and held in the hinge insertion part on the mounted part side, the cover body is prevented from lifting, and the cover body can be closed without using other parts such as fixing screws. It can be held well. Moreover, when opening a cover body, if a part of integral molding hinge is removed from the insertion hole of a hinge insertion part, a cover body can be open | released easily.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a perspective view of an inside / outside air switching case 1 for switching inside / outside air of a vehicle air conditioner to which the present invention is applied. The inside / outside air switching case 1 is provided with an outside air inlet 1a and an inside air inlet 1b at the top, and is pivotally supported so that a switching door (not shown) switches between the inside air and outside air. An insertion part for the air filter 10 is provided at the lower part of the inside / outside air switching case 1, and an insertion port 4 is formed at the end of the insertion part.
[0011]
The insertion port 4 of the air filter 10 is formed in a horizontally long rectangle, and a plate-like edge projection 5 is formed on the periphery of the four sides, and the insertion port 4 can be closed by a lid 2 described later. Configured. At the upper part of the edge portion of the insertion port 4, a locking portion 8 for locking the locking piece 7 of the lid 2 is projected. The inside / outside air switching case 1 and the lid 2 that covers the insertion port 4 are made of the same synthetic resin, and the lid 2 is integrally formed with the inside / outside air switching case 1 via an integrally formed hinge (integral hinge) 3.
[0012]
The integrally molded hinge 3 is formed at two locations on the lower side of the insertion port 4 of the inside / outside air switching case 1, and the lid body 2 is pivoted up and down via the pair of integrally molded hinges 3. 4 is closed and opened.

In this manner, the lid body 2 is rotated upward via the integrally formed hinge 3 so that the lid body 2 faces the insertion port 4. In this state, as shown in FIG. 4, the vicinity of the bent portion 3 a of the integrally molded hinge 3 is in contact with the hinge insertion portion 6. Then, when the lid 2 is pushed to the insertion port 4 as it is, the integrally formed hinge 3 is further bent through the bent portions 3a and 3b as shown in FIG. The portion pushes down the hinge insertion portion 6, and the hinge insertion portion 6 is elastically deformed downward.
[0016]
Then, when the lid 2 is pushed toward the insertion port 4 as it is and the edge recess 9 is fitted into the edge projection 5 on the case side, the contact portion with the hinge insertion portion 6 in the integrally formed hinge 3 gradually becomes inward. Finally, as shown in FIG. 2, the integrated hinge 3 is inserted into the insertion hole 6a of the hinge insertion portion 6 in a folded state.
[0017]
By such an operation, as shown in FIG. 2, the lid body 2 is closed so as to cover the insertion port 4, and the integrally formed hinge 3 of the lid body 2 is fitted into the hinge insertion portion 6 in a folded state. The lid 2 is securely closed. Therefore, in the state in which the lid 2 is closed in this way, the integrally molded hinge 3 is folded and fitted into the hinge insertion portion 6, and the folded state is completely maintained. 3 without receiving a repulsive force (restoring force) 3, and without using a separate part such as a fixing screw, it is possible to prevent a problem that the lid body 2 is lifted due to vibration or the like. Good sealing performance can be ensured.
[0018]
On the other hand, when the lid 2 is opened when the air filter 10 is replaced, the hinge fitting portion 6 is bent downward, and a part of the integrally molded hinge 3 is removed from the fitting hole 6a. If the holding state is removed, the function of the hinge can be restored and the lid 2 can be removed from the insertion port 4 and opened.
[0019]
6-10 has shown the attachment structure of the cover body of other embodiment. In this example, a claw portion 26 is provided next to the integrally formed hinge 3 of the lid 2, and the claw portion 26 is configured to be fitted into a claw insertion portion 16 provided on the lower side of the insertion port 4 when closed. . About the same part as the said embodiment, the code | symbol same as the above is attached | subjected to a figure, and the description is abbreviate | omitted.
[0020]
As shown in FIG. 6, a pair of claw insertion portions 16 project from the inside of the pair of integrally formed hinges 3 that connect the lid 2 to the inside / outside air switching case 1 and below the insertion port 4 of the case 1. The The nail insertion portion 16 is formed with an insertion hole 16a into which the claw portion 26 can be inserted. A pair of claw portions 26 project from the lower edge portion of the lid body 2 at a position corresponding to the claw insertion portion 16, and when the lid body 2 is put on the insertion opening 4 on the case 1 side, the claw portion 26. Is a structure that is inserted into the insertion hole 16 a of the nail insertion portion 16.
[0021]
In the lid mounting structure configured as described above, when the air filter 10 is inserted when the air filter 10 is replaced, and the lid body 2 is closed by covering the insertion port 4, the lid body 2 is shown in FIG. In this manner, the lid body 2 is rotated upward via the integrally formed hinge 3 so that the lid body 2 faces the insertion port 4. When the lid 2 is pushed to the insertion port 4 as it is, the integrally formed hinge 3 is further bent through the bent portions 3a and 3b as shown in FIG. The part 26 pushes down the nail insertion part 16 and proceeds to the case 1 side, and the nail insertion part 16 is elastically deformed downward. Then, when the edge recess 9 of the lid 2 is further fitted into the edge projection 5 on the case 1 side and the lid 2 is closed, the claw portion 26 is inserted into the insertion hole 16a of the claw insertion portion 16 as shown in FIG. The closed state of the lid body 2 is maintained.
[0022]
Thus, since the claw portion 26 is fitted and held in the claw insertion portion 16 with the lid body 2 closing the insertion port 4, the lid body 2 receives the repulsive force (restoring force) of the integrally formed hinge 3. Therefore, it is possible to prevent a problem that the lid 2 is lifted due to vibration or the like, and to ensure a good sealing property of the inside / outside air switching case 1.
[0023]
On the other hand, when the lid body 2 is opened when the air filter 10 is replaced, the lid body 2 can be removed from the insertion port 4 by bending the claw insertion portion 16 downward and removing the claw portion 26 from the insertion hole 16a. It can be removed and opened.
