Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for an armrest of an automobile or the like. More specifically, the present invention relates to a mounting structure for a relatively large armrest provided with a lidded storage section for storing small items.

Armrests in automobiles are used by passengers and passengers to rest their elbows, but armrests attached to doors are often relatively small and have the function of a handle. It is known to manufacture such small armrests by blow molding (for example,
56-111026), it has the advantage of being simple and inexpensive to manufacture.

On the other hand, as automobiles become more diverse, armrests are increasingly being provided with the function of accommodating small items.

Therefore, the inventor of the present invention conducted intensive research to manufacture a large armrest with such a storage function by blow molding, and found that a hollow synthetic resin armrest body is connected to the main body via a bendable connecting part. Developed an armrest in which the lid is integrally formed by blow molding, and then the upper surface of the main body corresponding to the lid is cut out to form an opening, and the internal space of the main body becomes a storage part that can be closed with the lid. did.

FIG. 1 is a perspective view showing an example of the armrest, FIG. 2 is an enlarged sectional view taken along line A-A in FIG. 1, and FIG.
The figure is an enlarged sectional view taken along the line B--B in FIG. 1.

1 is a hollow armrest main body, and 2 is a lid part connected to the main body 1 via a bendable connecting part 3. The main body 1, the lid part 2 and the connecting part 3
is integrally molded by blow molding. An opening 4 is provided on the upper surface of the main body 1, and the opening 4 is provided in the upper surface of the main body 1, as shown in FIG.
and the lid part 2 are integrally molded by blow molding, and then the part corresponding to the lid part 2 on the upper surface of the main body 1 [shaded part 4]
a] is formed by cutting out.

The lid part 2 can be opened and closed by a bendable connecting part 3, and its protruding edge 5 engages with a locking part 6 of the main body 1 in the closed state.

Thus, the hollow portion of the main body 1 constitutes a storage portion 7 for storing small items, etc., which can be closed with the lid portion 2.

The main body 1 has a handle part 9 by recessing a part of the mounting surface 8.
are integrally provided. When the armrest is attached to a location other than the door, or when a handle is provided separately from the armrest, the handle portion 9 is omitted.

A groove portion 10 is provided on the front surface of the main body 1.
This has a decorative role, and the remaining portion of the opening 4 that is cut out constitutes a locking portion 6.

A reinforcing member 11 is preferably provided inside the opening 4 of the main body 1 . In the armrest, since the opening 4 is provided in the blow-molded main body 1, the rigidity of the closed structure, which is a characteristic of blow-molded products, tends to be impaired. Therefore, the front wall of the main body 1 deforms inward at the opening 4, causing problems such as the lid 2 and the main body 1 not matching when the lid 2 is closed. The reinforcing member 11 is for preventing the above-mentioned deformation in the opening 4 of the main body 1.

As the reinforcing member 11, as shown in FIGS. 2 and 5 (cross-sectional view taken along the line C--C in FIG. 2), a wire such as a hard steel wire with both ends bent into a hook shape can be used. This material is bent as shown by the broken line in FIG. 5 and inserted into the main body 1 through the opening 4, and then when the force is released, it is fixed by its repulsion.

An introduction hole 13 for a screw screw 12 is provided in the main body 1, and an insertion hole 1 is provided at the bottom of the introduction hole 13.
A mounting seat 14 having a diameter 4' is provided.

To attach the armrest to a door, a hole 17 into which the grommet 16 can be inserted is bored in the door trim board 15, and a hole 19 into which the tip of the grommet 16 can be inserted is bored in the inner panel 18.
The grommet 16 is fitted into the hole 19 of the inner panel, the screw 12 is screwed into the grommet 16 through the introduction hole 13 of the main body 1, and the armrest is fixed to the door when tightened.

However, when the blow-molded hollow armrest is installed as described above, the mounting seat 14 falls into the hole 17 of the door trim board 15 by tightening the screw 12 as shown in FIG. dent,
There is a problem that the appearance becomes unsightly.

In view of the above points, the present invention provides a mounting structure that can solve the problem of poor appearance when mounting a large hollow armrest.

That is, the present invention includes a main body of a synthetic resin hollow molded body, an openable and closable lid part that covers an opening provided in the upper wall of the main body, and a front wall of the main body in the vicinity of the opening in the main body. a reinforcing member disposed between the rear wall and the rear wall so as to pinch both walls; and a reinforcing member extending between the front wall and the rear wall of the main body, with both ends thereof being integrated with the front wall and the rear wall. A cylindrical part having an introduction hole for a tightening member opening in the front wall inside the cylindrical part, and a mounting seat left around the cylindrical part in the rear wall corresponding to the bottom of the introduction hole. When fixing a large armrest consisting of an insertion hole for a fastening member drilled by the fastening member to another member using the fastening member, the fastening member provided on the mounting surface of the rear wall of the armrest main body. A substantially cylindrical protrusion whose height is approximately equivalent to the thickness of the other member is integrally formed around the periphery of the insertion hole for the other member, and the protrusion is fitted into the hole drilled in the other member and then tightened. The present invention relates to an armrest mounting structure characterized in that an armrest main body is fastened to another member using a member.

Next, the present invention will be explained with reference to the drawings, taking as an example a large armrest having a lidded storage part formed by the above-mentioned blow molding.

FIG. 7 is a perspective view of one embodiment of the armrest according to the present invention, as seen from the back side. FIG. 8 is a sectional view (corresponding to the enlarged sectional view taken along the line DD in FIG. 7) showing an embodiment of the mounting structure of the present invention. Note that the perspective view of the armrest in FIG. 7 viewed from the front side is the same as that in FIG. 1, and the enlarged sectional view taken along the line E--E in FIG. 7 is the same as that in FIG. 2. In FIGS. 7-8, the same members as in FIGS. 1-6 are designated by the same drawing symbols.

The armrest of the present invention is composed of a hollow armrest main body 1 and a lid part 2 connected to the main body 1 via a bendable connecting part 3, like the armrest described above, and these are integrally formed by blow molding. It is molded. An opening 4 is formed on the upper surface of the main body 1 by cutting out the hatched portion 4a.
The internal space of the main body 1 constitutes a housing section 7 that can be closed with a lid section 2.

The main body 1 is provided with a cylindrical part that extends between the front wall and the rear wall, and whose both ends are integrated with the front wall and the rear wall. An introduction hole 13 is provided, and a mounting seat 4 having an insertion hole 14' is provided at the bottom of the introduction hole 13. A substantially cylindrical protrusion 20 that protrudes outward is integrally formed on the mounting seat 14 . The protrusion 20 is configured to be inserted into a hole 17 made in the door trim board 15, and its height is approximately the same as the thickness of the door trim board 15.

To attach the armrest to the door, fit the tip of the grommet 16 into the hole 19 drilled in the inner panel 18, then insert the protrusion 20 of the main body 1 into the hole 17 of the door trim board 15, and then tighten the screw 12. When introduced through the introduction hole 13, screwed into the grommet 16, and tightened, the armrest is fixed to the door. In that case, since the tip of the protrusion 20 is in contact with the bottom surface of the grommet 16, the mounting seat 14 will not fall into the hole 17 even when the screw 12 is tightened.
There is no fear that the front surface of the main body 1 will be dented.

To manufacture the armrest according to the present invention, first, a main body 1 (without an opening 4) as shown in FIG. Blow mold. In blow molding, for example, a parison is extruded from an extrusion die, and the parison is molded into a mold having a cavity shaped to correspond to the main body 1 and the lid part 2, as shown in FIG. Then, the parison is placed between split molds 21 having compression parts 21a corresponding to the connecting parts 3, the molds 21 are closed, a gas such as air is blown into the parison from the blowing port 22, and then the molds are closed. This is done by opening 21 and taking out the molded product. In this way, a molded product is obtained in which the hollow body 1 and the lid part 2 are connected by the thin, bendable connecting part 3. Next, a portion of the main body 1 corresponding to the lid portion 2 (hatched portion 4a in FIG. 4) is cut out to provide an opening 4, and then preferably an auxiliary member 11 is provided to obtain an armrest.

The synthetic resin constituting the armrest is not particularly limited as long as it can be blow molded, and examples include polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, polyvinyl chloride, polyamide, polyester, and ABS resin. etc. can be mentioned. In order to improve the feel of the armrest and reduce impact, it may have a two-layer structure in which the inner layer is made of hard resin and the outer layer is made of soft resin. Such a two-layer armrest can be made by simultaneously blow molding a parison made of a soft resin such as low-density polyethylene or soft polyvinyl chloride, and a parison made of a hard resin such as polyester, ABS resin, polypropylene, or high-density polyethylene.
