Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a pine clip for attaching thin pine and the like.

(Prior technology) Utility Model No. 51-118223, Utility Model No. 52-69741, Utility Model No. 52-69741
54-38248, Japanese Unexamined Patent Publication No. 55-155602, etc., pine clips are known from the past.

(Problem to be solved by the invention) All of the conventional products are equipped with cylinder bodies that snap together into mounting holes drilled in the mat, and simply pass through the upper and lower members, so it is difficult to install horizontally on the mat. If a tensile force is applied in this direction, the attachment hole may deform and expand, or the mat may tear from the edge of the hole and may come out of the clip.

(Means for solving the problem) Therefore, the present invention is to attach either a female cylinder with an outer diameter that matches the mounting hole of the mat, or a male cylinder that is pushed into the female cylinder and engages with a snap, to the bottom surface of the top plate. In the pine clip, the pine clip is composed of an upper member with the upper member and a lower member with the other member on the upper surface of the lower plate, and which holds the pine between the upper plate and the lower plate by pushing the male cylinder into the female cylinder and engaging them with a snap. A recessed line located around the mounting hole is provided on one of the facing surfaces of the upper surface plate and the lower surface plate, and a protruding line is provided on the other side for pushing the pine into the grooved line outside the mounting hole. It is characterized by

(Operation) Insert the female cylinder into the mounting hole of the mat from above or below, push the male cylinder into the female cylinder from the opposite direction, and snap-engage the upper member and the lower member, and then the upper plate of the upper member and the lower member. When the pine is sandwiched between the bottom plates of the pine, a convex strip located around the pine mounting hole and provided on one of the opposing surfaces of the top plate and the bottom plate is provided around the pine mounting hole on the other side. Push it into the groove.

(Embodiment) In the illustrated embodiment, 1 and 2 indicate an upper member and a lower member molded from plastic that engage with each other with a snap and sandwich the mat M from above and below. In this embodiment, the upper member contacts the upper surface of the mat with its lower surface. It has a top plate 3, and a male cylinder 4 that protrudes downward from the central lower surface of the top plate beyond the peripheral edge 3' of the top plate. 5 are integrally provided.

The lower member 2 has a lower plate 6 that contacts the lower surface of the mat from below, and an integral female cylinder 7 that stands upward from the inner periphery of the lower plate. A non-return pawl 8 which snaps into engagement with the non-return pawl 5 is provided to project inward. The female cylinder 7 here refers to one in which the male cylinder 4 can be fitted almost snugly into its inner periphery, with the female cylinder facing downwards on the bottom surface of the top plate, and the male cylinder facing upwards on the top surface of the bottom plate. It may be provided. The mat is provided with a mounting hole 9 that fits the outer periphery of the female cylinder, and the floor panel P of, for example, an automobile, on which the mat is to be laid, is provided with a head and neck that snap into the inner periphery of the male cylinder. Rivet 1
0 is attached. For this purpose, an inward bulge 4' is provided at the lower end of the inner periphery of the male cylinder 4 for snap-engaging with the neck 10a of the rivet 10 to hold the head 10b inside. This bulge 4' may also be a non-return claw like the above-mentioned non-return claws 5 and 8, but it is preferably a bulge in order to easily peel the mat from the floor. The non-return claws and the bulges may be continuous in the circumferential direction or may be dispersed in the circumferential direction.

To fix the mat on the floor, insert the female cylinder 7 from below into all the mounting holes of the mat, push the male cylinder 4 into each female cylinder from above, and connect both the upper and lower members with the non-return claw strip 5, The mat is sandwiched between the top plate 3 and the bottom plate 6 by snap-engaging the 8 pieces together, and then the male cylinder of each top member is pressed onto the head of the rivet 10, respectively. Conventional pine clips simply attach to the mounting holes of the pine and fix the pine to the floor as described above, so when a tensile force is applied to the pine in the lateral direction, the pine clips are attached to the top plate 3.
It can move laterally between the lower plate 6 and the female cylinder, and the mounting hole 9 can be expanded and deformed by the female cylinder, or it can be torn from the edge of the hole.

For this reason, on one of the opposing surfaces of the top plate 3 and the bottom plate 6, the concave line 11 and the convex line 12 located around the mounting hole 9 of the mat are not necessarily continuous in the circumferential direction as in the illustrated embodiment. Although it is not necessary to disperse the grooves in the circumferential direction, it is preferable that only the grooves 11 are arranged continuously in an annular shape.

As a result, when the upper member and the lower member are snapped together and installed in the mounting hole 9 of the mat, the part outside the edge of the mounting hole is pushed into the grooved line 11 by the protruding line 12, so that after fixing it to the floor. , even if it is pulled laterally,
Since the portion pushed into the groove resists the tensile force, there is no possibility that the mounting hole 9 will expand and deform or break.

In the embodiment shown in FIG. 1, the protruding stripes 12 are integrally provided on the lower surface of the upper surface plate facing downward, but when the grooved stripes 11 are provided on the lower surface of the upper surface plate, they may be provided on the lower surface plate facing upward.

(Effects of the invention) In this invention, the pine is not only sandwiched between the top plate of the upper member and the bottom plate of the lower member, but also the mounting hole of the pine is formed with a protrusion provided on one of the opposing surfaces of the two plates. The periphery is pushed into the groove provided on the other side, and the part pushed into the groove resists the lateral pulling force, causing the mat's mounting hole to expand and become deformed, and the mat to be pushed out of the mounting hole. It can completely prevent tearing.
