[0002]

2. Description of the Related Art Generally, floor mats (service mats) are laid on the floor of an automobile. Although it is not preferable to move the floor mat on the floor, it must be removed by cleaning or the like. For this reason, a convex non-slip is provided on the back surface of the floor mat to prevent the floor mat from moving or to be detachably locked at a predetermined place.

As means for locking the floor mat at a predetermined position on the floor surface, a hook having fitting legs, as shown in Japanese Utility Model Application Laid-Open No. 6-6090, is screwed to the floor mat, and the fitting legs of the hooks are mounted on the interior. There is known a material which is attached to a predetermined position of a carpet laid on a floor surface as a material and fits into an eye.

[0004]

The eyelet is formed by inserting a tubular metal fitting into a hole provided in a carpet and crushing both ends by a special machine. As described above, when using the eye as the hook stopper, a separate process of crushing both ends of the tubular metal fitting with a dedicated machine is required, which is troublesome and increases the assembly cost.

[0005] The present invention solves the above-mentioned problem in the hook stopper, and provides a hook stopper that can be easily attached to a carpet, has excellent assembling workability, and can securely lock the hook. With the goal.

[0006]

In order to achieve the above object, a hook stopper according to the present invention has a first flange having a first flange portion extending outward at an outer peripheral edge at one end of a first cylindrical portion. (1) a second flange portion having a stopper and a hook engaging claw on an inner peripheral surface on one end side of the second cylindrical portion, and extending outward at an outer peripheral edge on the other end side of the second cylindrical portion; And a second stopper of the second stopper from the back side of the carpet into the first cylindrical portion of the first stopper inserted from the front side of the carpet into the through hole provided in the carpet. A first engaging claw provided on the inner peripheral surface on the other end side of the first cylindrical portion and a second engaging member provided on an outer peripheral surface on one end side of the second cylindrical portion. The configuration was such that the claws were engaged and assembled. As described above, the hook stopper of the present invention can be attached to the carpet simply by combining the first stopper and the second stopper from both the front and back sides of the carpet so as to sandwich the carpet. In addition, the fitting projection of the hook with which the engaging ring of the floor mat is engaged is pushed into the second tubular portion from the surface side of the carpet and is locked by the hook engaging claw of the second stopper. Even if an external force acts in the direction in which the hook engaging projection is pulled out, the second flange portion located on the back surface of the carpet becomes a resistance to the external force, and the hook stopper is prevented from coming off the carpet, and The two stoppers are merely drawn toward the first stopper, and the first stopper and the second stopper do not separate.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the hook stopper 1 of the present invention includes a first stopper 11 located on the front surface 4a side of the carpet 4 and a second stopper 12 located on the back surface 4b side of the carpet 4. The first stopper 11 and the second stopper 12 are formed by being combined so as to sandwich the carpet 4.

The first stopper 11 is a molded article made of a synthetic resin having flexibility. As shown in FIGS. 2 and 3, the first stopper 11 has a first cylindrical portion 11a at the center thereof. Cylindrical part 11a

Hook engaging claw 12g for locking fitting protrusion 23
Are integrally formed. The hook engaging claw 12g has a base end located on the inner peripheral edge of one end 12b of the second tubular portion 12a, and a tip formed toward the inside of the tubular portion 12a and toward the other end 12c. As shown in FIG. 4, the hook engaging claw 12g is provided with four vertically slit slits 12h. Here, the slit 12h is for facilitating bending of the hook engaging claw 12g when inserting the fitting protrusion of the hook. Although the number of the slits 12h is not particularly limited, it is preferable to provide about 3 to 4 slits in order to maintain strength for holding the fitting projection. On the other hand, a second flange portion 12d extending outward is formed at a peripheral portion on the other end 12c side of the second cylindrical portion 12a. Like the first flange portion 11d of the first stopper 11, the second flange portion 12d is formed in an umbrella shape, that is, a tapered shape in a sectional view, and this portion comes into contact with the carpet. Thereby, the carpet is pressed down with elasticity. Here, a plurality of projections 12i having sharp tips are provided on the inner side of the second flange portion 12d, that is, on the surface facing the carpet. The hook stopper 1 is prevented from turning or shifting. Note that a similar projection may be provided inside the flange of the first stopper. Further, in addition to the protrusions, a protrusion may be provided inside the flange to surround the cylindrical portion in order to suppress the displacement of the hook stopper.

Next, a procedure for disposing the hook stopper 1 according to the present invention on a carpet will be described below. That is, as shown in FIG. 5, the first stopper 11 is provided on the front surface 4a side with respect to the through hole 4c provided at a predetermined position of the carpet 4, and the back surface 4b is provided.
The second stoppers 12 are set on the sides, and first, the cylindrical portion 11a of the first stopper 11 is inserted from the front side of the carpet 4. Then, the second cylindrical portion 12a of the second stopper 12 is pushed into the first cylindrical portion 11a of the first stopper 11 from the back side of the carpet 4, and the first engagement claw 11f and the second engagement claw 12f are pushed. And are engaged. Thereby, the first stopper 11
And the second stopper 12 are combined and integrated so as to sandwich the carpet 4 to form the hook stopper 1 of the present invention. As described above, since the hook stopper 1 of the present invention is easily attached to the carpet 4, the stopper 1 can also be easily attached when the worker lays the carpet 4 on the vehicle body. For this reason, it is not necessary to provide a separate process for mounting unlike the eyelet.

Next, a procedure for locking the floor mat using the hook stopper according to the present invention will be described below. As shown in FIG. 1, in the hook stopper 1 attached to the carpet 4, first, the hook 2 is attached. Here, as the hook 2, for example, a plate-shaped portion 21 whose both ends are bent toward the back surface 2 b, and provided on the surface 2 a of one end of the plate-shaped portion 21 and bent toward the other end One having a hook portion 22 as a locking portion and a fitting projection 23 provided on the back surface 2b side of the other end is used. The fitting protrusion 23 is formed by a leg 23 extending from the plate surface of the plate-shaped portion 21.
a and a bulging portion 23b provided at the tip of the leg 23a. The tip of the bulging portion 23b is tapered so as to taper, and the fitting protrusion 23 has a mushroom shape as a whole. As shown in FIG. 5, the hook 2 having the above-described configuration
Is pushed into the tubular portion of the hook stopper 1 from the surface 4a side of the carpet 4, and the bulging portion 23b engages with the hook engaging claw 12g of the second stopper 12, whereby the carpet 4
At a predetermined position.

When the engagement ring 3a of the floor mat 3 is fitted into the hook portion 22 of the hook 2, the floor mat 3 is locked at a predetermined position, and the displacement of the floor mat 3 is effectively prevented. By the way, when the floor mat is pulled by the driver's foot operation, or when the floor mat is removed, the floor mat is not removed completely and the engaging ring of the floor mat and the hook of the hook are completely removed. If the hook is pulled too hard, a force may be applied to the hook in a direction in which the hook is pulled out from the hook stopper. In such a case, if the first stopper on the front side of the carpet is provided with a hook engaging claw for engaging the fitting projection of the hook, the first stopper is not released from the first stopper. A force may be applied between the stopper and the second stopper, and the first stopper and the second stopper may be separated and separated. As described above, when the first stopper and the second stopper are separated, the second stopper moves on the back side of the carpet and is lost, and cannot be combined with the first stopper again. Is unable to be fixed at a predetermined position.

However, the hook stopper 1 is characterized in that the hook stopper is provided on the second stopper located on the back side of the carpet, and the hook engaging projection is engaged with the hook engaging tab. Even if the hook is pulled up, the hook engaging claw is pushed and expanded in the direction of expanding the second cylindrical portion, so that the first cylindrical portion and the second
The fitting force of the tubular portion is increased, and the first stopper and the second stopper are less likely to come off. Moreover, even if the hook is pulled up and forcibly removed, the external force acts directly on the second stopper 12 and not on the first stopper 11. Therefore, when the fitting projection 23 of the hook 2 is pulled out, the second stopper is drawn toward the first stopper, so that the first stopper and the second stopper do not separate from each other. In the stopper 1, disassembly into the first stopper and the second stopper is suppressed, and the occurrence of the inconvenience can be effectively prevented. Further, in the hook stopper 1, since the second flange portion 12d functions to resist an external force in the pulling-out direction, the inconvenience that the hook stopper 1 itself comes off the carpet and the floor mat cannot be locked may occur. Can be prevented.

[0014]

According to the hook stopper of the present invention, the carpet is sandwiched from above and below by the first stopper and the second stopper, the cylindrical portions of the carpet are fitted to each other, and the engaging claws provided thereon are engaged. It can be attached to a carpet simply by making it easy to attach. Therefore, the worker can easily attach the hook stopper when laying the carpet, so that it is not necessary to provide a separate process for attaching the hook stopper. Therefore, the assembling process can be simplified, which contributes to a reduction in assembling cost.

Further, in the hook stopper of the present invention, the hook engaging claw that engages with the fitting projection of the hook is provided on the second stopper on the back side of the carpet. The stoppers are merely pulled toward the first stopper, and are not separated and separated. For this reason, it is effectively prevented that the floor mat is displaced due to the detachment of the stopper and the release of the hook.
