The boss 5 may be fixed by spin welding or by using an adhesive. However, if an adhesive is used, it takes a long time (usually about 1 day) to dry the adhesive, and There is a drawback that the agent is apt to adhere to places other than the adhesion site. In contrast,
In the case of spin welding, there are the above-mentioned drawbacks, the work efficiency is excellent, and the finish can be neatly cleaned.

The lid 3 is provided with box-shaped hollow portions 6 ... Which protrude from the lower surface of the lid 3 and which are open to the surface of the lid 3 at positions corresponding to the bosses 5, respectively. Here, the lid 3 is a plastic molded product and the hollow portion 6 is integrally provided, but the hollow portion 6 may be separately molded and then assembled to the lid 3 later.

The hollow portion 6 has an open upper surface 7 that is opened in a rectangular shape on the surface of the lid body 3, and parallel inner and outer side walls 8 that face the inner side surface 1b of the storage recess 1 along the opposite long sides thereof. 9
And front and rear walls 10 and 11 along the opposite short sides, and a bottom wall 12 that closes the bottom of the hollow portion 6. And the inner surface of the storage recess 1
The outer wall 8 facing 1b is formed with a U-shaped notch 13 having a width through which the leg portion 5c of the boss 5 passes from the lower end thereof.
The bottom wall 12 is formed with a U-shaped cutout portion 14 which is connected to the cutout portion 13 and through which the shaft portion 5a of the boss 5 and the head portion 5b pass. In addition, on the inner surfaces of the both side walls 8 and 9, a pair of mounting pieces, which are slanted vertically, are arranged at positions relatively close to the rear wall 11 so as to face each other and project inward.
15 and 15 are provided so that the upper ends of the two mounting pieces 15 are lower than the open upper surface 7 by a predetermined distance l.

The fastener 4 has a P-shaped side surface, includes an upper plate 16 that closes the open upper surface 7 of the hollow portion 6 and a bulging portion 17 that protrudes from the lower surface of the upper plate 16 in a semicircular shape. It has rigidity and elasticity, and is integrally molded with POM (polyoxymethylene), for example.

On the fastener 4, from the upper plate 16 to the bulge 17, the boss 5
A pair of left and right holding grooves 18, 18 whose one end is open to receive the head portion 5b is provided on both sides in the width direction. Opening end 1 of each holding groove 18
8'is composed of an outer groove 18a which is opened in a generally T shape on the upper surface of the upper plate 16 and is opened in a U shape on both sides in the width direction, and an inner groove 18b which intersects with the end of the outer groove 18a in a T shape. The width of the outer groove 18a in the front and rear is approximately matched with the diameter of the shaft portion 5a of the boss 5, and the length of the front and rear of the inner groove 18b is approximately matched with the diameter of the head 5b of the boss 5.

Then, in the lower portion of the bulging portion 17, a thin-walled portion bent in an arc shape along the bottom surface of the bulging portion 17 with an arc-shaped hollow groove 19 interposed therebetween.
Form 20. The height from the arcuate apex P of the lower surface of the thin portion 20 to the upper surface of the upper plate 16 is approximately equal to the depth from the open upper surface 7 of the hollow portion 6 of the lid 3 to the upper surface of the bottom wall 12, A projecting portion 21 having a small semi-circular cross section, which is raised from the lower surface of the thin portion 20, is formed at a position slightly forward of the apex P in the width direction.

On the other hand, in the upper plate 16, the thickness of the lower surface is gradually reduced toward the other end so that the thickness of the portion of the hollow portion 6 that abuts the mounting piece 15 matches the predetermined distance 1 and the other end Has a U-shaped cutout from its end face, and forms an insertion recess 23 into which the cutting edge of the driver 22 can be inserted between the end face and the inner surface of the rear wall 11 of the hollow portion 6.

 Next, a procedure for attaching the lid 3 will be described.

First, the lid body 3 may be attached so as to fit the opening upper surface 1a of the storage recess 1, and at that time, the shaft portion 5a and the head portion 5b of the boss 5 are passed through the notches 14 in the bottom wall 12 of the hollow portion 6 of the lid body 3. Is fitted into the hollow portion 6 from below, and the leg portion 5c of the boss 5 is fitted into the cutout portion 13 of the outer wall 8 of the hollow portion 6, so that the shaft portion 5a and the head portion 5b of the boss 5 are inside the hollow portion 6. Project sideways (Fig. 3). still,
The lid 3 has a boss 5 at the upper end for closing the notch 13 of the hollow portion 6.
When the leg part 5c of the
The upper surface 1a of the opening is held substantially flush with the bottom surface of the rear trunk, and is prevented from falling into the storage recess 1.

Next, one end of the upper plate 16 of the fastener 4 is turned down, and as shown in FIG. 3, it is inserted from the open upper surface 7 of the hollow portion 6 of the lid 3 into the inside. At that time, the boss 5 is aligned with the inner surface of the rear wall 11 of the hollow portion 6 and the holding groove 18 for the boss 5 and the fastener 4 is provided.
Are inserted so that the open ends 18 'of each of them face each other. By making the distance between the boss 5 and the inner surface of the front wall 10 of the hollow portion 6 narrower than the thickness between the upper plate 16 and the bulging portion 17 of the fastener 4, the fastener 4 is erroneously placed within the distance. I am trying not to insert.

When the fastener 4 is inserted in this way, the fastener 4 is moved in parallel in the hollow portion 6 of the lid 3 toward the boss 5, and from the opening end 18 'of the holding groove 18 to the shaft portion 5a of the boss 5 and Insert the head 5b. At that time, the shaft portion 5a of the boss 5 is fitted into the outer groove 18a of the holding groove 18, and the head portion 5b is fitted into the inner groove 18b. And
In this state, the other end of the fastener 4 may be pushed down toward the hollow portion 6.

Thus, when the fastener 4 is folded down, the outer groove 18 of the holding groove 18
Rotating around the shaft portion 5a of the boss 5 that projects laterally from a, the protrusion 21 on the lower surface of the thin portion 20 of the fastener 4 becomes the bottom wall 12 of the hollow portion 6.
Abuts the upper surface of the When the fastener 4 is strongly pushed in here, the protrusion 21 is pushed by the upper surface of the bottom wall 12 and the thin portion 20 slightly bends toward the hollow groove 19. Then, when the fastener 4 is pushed further hard, the fastener 4 is further rotated, and when the apex of the protrusion 21 goes slightly over the upper surface of the bottom wall 12, the thin portion 20 snaps back. At that time, since the position of the protrusion 21 is off the apex P of the thin portion 20, the shaft portion of the boss 5 is attached to the fastener 4.
A clockwise torque about 5a works.

Therefore, if the user feels a clicking sensation that occurs when the thin portion 20 snaps back, even if the pressing of the fastener 4 is stopped halfway, the fastener 4 will rotate due to the rotational force and its upper plate When the lower surface of 16 abuts on the upper end of the mounting piece 15 in the hollow portion 6, the rotational force is received and it stands still. Even in this stationary position, since the protrusion 21 is in contact with the upper surface of the bottom wall 12, the restoring force of the thin portion 20 works, and the turning force causes the fastener 4 to move inside the hollow portion 6 of the lid 3. Locked in.

Thus, when the fastener 4 is mounted in the hollow portion 6 of the lid body 3, the open upper surface 7 of the hollow portion 6 of the lid body 3 becomes the upper plate of the fastener 4.
The upper surface of 16 closes the surface of the lid 3 substantially flush with the surface of the lid 3.
At the same time, the closed lower end of the outer groove 18a of the holding groove 18 comes into contact with the shaft portion 5b of the boss 5 in the storage recess 1 from below so that the boss 5 is prevented from coming off from the notch 13 of the hollow portion 6 and the lid is closed. The body 3 does not come off the storage recess 1.

Also, when the fastener 4 is rotated, the thin wall portion 20 tries to push up the shaft portion 5b of the boss 5 by the edge of the outer groove 18a of the holding groove 18 due to the restoring force, but the boss 5 is fixed. Therefore, the lid 3 is pulled toward the storage recess 1 in reverse. Therefore, even if it is insufficient to close the lid body 3, the lid body 3 is completely closed by the force of being drawn into the storage recess 1. Further, since the restoring force of the thin portion 20 is applied even in the rest position of the fastener 4, the shaft portion 5b of the boss 5 has the closed upper end of the cutout portion 13 of the hollow portion 6 and the outer groove 18a of the holding groove 18. It is elastically clamped from above and below by the closing lower end of the lid 3, and the lid 3 is attached to the storage recess 1 without backlash.

On the other hand, when the lid 3 is opened, the blade edge of the driver 22 is inserted into the insertion recess 23 of the fastener 4, and the insertion recess 23 is pryed by the blade edge so that the other end of the upper plate 16 of the fastener 4 is closed. The hollow part 6
It is sufficient to pull it upward from the open upper surface 7.

In this way, when the other end of the fastener 4 is pulled up, the fastener 4 rotates counterclockwise around the shaft of the shaft 5b of the boss 5 as a fulcrum, and the protrusion 21 thereof is pushed onto the upper surface of the bottom wall 12. Thin section 20
When is further bent toward the hollow groove 19 and the apex of the protruding portion 21 goes slightly over the upper surface of the bottom wall 12, the thin portion 20 snaps back and a click feeling occurs at that time, and the fastener 4 Free to rotate.

Then, the other end of the upper plate 16 of the fastener 4 is held and further rotated to bring the fastener 4 into an upright state substantially vertical to the hollow portion 6 of the lid 3. When it is rotated to this upright position, its holding groove 18
Since the open end 18 ′ of the open side is opened laterally, the fastener 4 can be moved laterally in the hollow portion 6 and the boss 5 can be pulled out from the open end 18 ′.

In this way, when the boss 5 is pulled out, the lid 3 is moved to the storage recess 1
And the lid 3 is removed from the upper surface of the opening of the storage recess 1.
When horizontally raised from 1a, the boss 5 passes through the lower end of the opening of the notch 13 and the notch 14 and comes out from inside the hollow portion 6,
The lid 3 is also removed from the storage recess 1.

FIG. 10 shows a second embodiment of the fastener of the present invention. In this embodiment, a tack-shaped knob 24 extending upward is provided on the upper surface of the other end of the upper plate 16 of the fastener 4. Is provided integrally. Incidentally, the knob 24 may be separately molded and attached later, or

FIG. 11 shows another embodiment of the fastener of the present invention. In this embodiment, a concave grip portion 25 into which a finger can be inserted is provided at the other end of the upper plate 16 of the fastener 4. It is provided.

The handle portion 25 has the other end of the upper plate 16 bent downward in a U shape, and the tip end portion thereof is further bent inward toward the substantially L shape so that the upper surface is opened inside and the cross section L is formed. A void portion 26 that is bent in a letter shape is formed. The same components as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

In this embodiment, a finger is inserted from the upper surface of the opening of the empty portion 26,
A finger can be inserted under the tip folding portion 27 of the upper plate 16 and pulled up.

According to this embodiment, similar to the second embodiment,
Not only can the fastener 4 be easily removed without using the screwdriver 22, but since the knob 24 does not travel from the upper surface of the upper plate 16 as in the second embodiment, the upper surface of the upper plate 16 can be removed. Can be kept flat with the surface of the lid 3.

In each of the embodiments shown in the drawings, the holding grooves 18 are formed on the left and right sides of the fastener 4 in the width direction so that the boss 5 can be used when protruding from any direction. In other words, the turning direction of the fastener 4 can be aligned with the direction in which it is easy to work.

Further, although the opening end 18 ′ of the holding groove 18 is opened on the upper surface of the upper plate 16, the opening end 18 ′ of the holding groove 18 may be opened on the left front surface of the fastener 4.

On the other hand, as the locking means, the protrusion 4 on the lower surface of the thin portion 20 of the fastener 4 and the bottom wall 12 of the hollow portion 6 of the lid 3 are used to secure the fastener 4
In addition to the above, the recesses are engaged with each other in the hollow portion 6, but in addition, an uneven portion that engages with each other is formed between the fastener 4 and the hollow portion 6, and the fastener 4 is engaged with the hollow portion 6 by the engagement of the uneven portion. It may be locked inside.

Further, the present mounting structure is suitable not only for the lid body 3 for closing the storage recess 1 for storing the spare tire 2 in the rear trunk of an automobile but also for the lid body which is used relatively infrequently. It can be used for case lids, various lids for furniture and home appliances, and doors for houses.
