Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a clip that can fasten plate-like objects without a fastener.

[Problems that conventional technology and ideas try to solve]

As shown in Fig. 4, this type of clip is well known in that the elastic legs made of resin can be pushed along the inclined surface without any tools, and that a clipping action can also be obtained on the inclined surface. It is. However, with this structure, the fastening force was weak and looseness was likely to occur.

Therefore, the object of the present invention is to provide a clip of the type mentioned at the beginning which has a strong fastening force.

[Means and actions for solving problems]

It consists of a male clip 10 consisting of a cylinder 12 with a smaller diameter that continues to the head 11 and its back surface 11a, and a female clip 20 formed as a sleeve 21 into which the cylinder 12 is fitted. At least two grooves 13, 13a are symmetrically formed on the surface of the cylinder 12, extending from the tip toward the back surface 11a, and then bending parallel to the back surface, and a groove of the bent portion 13b is formed at the outer corner of the bent portion 13b. Elastic guide surface 13 that runs in parallel from the tip side so as to narrow it down.
c was formed. The inner surface of the sleeve 21 has a groove 13,
forming a protrusion 21a that engages with 13a and 13b;
Further, an elastic portion 22 is formed at the rear end or back surface 11a of the sleeve 21.

[Effect]

When the male clip 10 is inserted into the hole in the plate and the protrusion 21a of the female clip 20 is fitted into the groove 13 at the tip of the male clip 10 and pushed in the direction of the head 11, the protrusion 21a strides inside the groove 13 and forms an elastic guide surface. 13c and when pressed further, it is automatically guided into the groove 13a against the reaction force of the elastic guide surface 13c and the elastic portion 22. In this state, the protrusion 21a
is positioned within the groove 13a by the reaction force of the elastic guide surface 13c, and the play of the protrusion 21a within the groove 13a is also absorbed by the reaction force of the elastic portion 22.

[Example of idea]

The clip according to the present invention consists of a male clip 10 (Fig. 1) consisting of a dish-shaped head 11 and a cylinder 12 of a smaller diameter following its flat back surface 11a, and a female clip 20 (Fig. 2) which is a sleeve 21 into which the cylinder 12 is fitted. ) is composed of two members. On the surface of the cylinder 12, a guide groove 13 extending linearly from its tip in a direction orthogonal to the flat back surface 11a and a stopper groove 13a parallel to the flat back surface 11a are formed symmetrically with respect to the central axis of the cylinder.
Individually formed. At the outer corner of the curved portion 13b from the guide groove 13 to the stopper groove 13a, an elastic guide surface 13c is formed as a flexible wall surface shaped to round off the corner. The depth of the stopper groove 13a corresponds to the diameter of the cylindrical projection 21a (described later),
A claw 13d is formed at the inner corner. The distance between the stopper groove 13a and the flat back surface 11a is set to correspond to the thickness of the plate-shaped object to be held,
A spacer may be interposed if necessary.

On the other hand, the inner surface of the sleeve 21 has grooves 13, 13a.
and a cylindrical protrusion 2 that can engage the bent portion 13b.
1a, and a fin-like elastic portion 22 is formed at the tip of the sleeve.

Both the male clip 10 and the female clip 20 are made of synthetic resin, and each part is integrally molded.

In use, as shown in FIG.
Insert the protrusion 2 of the female clip 20 from the opposite side.
When 1a is inserted into the guide groove 13 and pushed in the direction of arrow F, it slides along the guide groove 13 toward the flat back surface 11a. The protrusion 21a is the elastic guide surface 13c
When it hits, the elastic guide surface 13c is displaced to the dotted line position (FIG. 1a) due to its elasticity, and further fitted into the stopper groove 13a along the inclined surface. In this state, the protrusion 21a, the elastic guide surface 13c and the claw 13d
It is reliably held within the stopper groove 13a.
Further, due to the elasticity of the elastic portion 22, variations in the thickness of the sleeve 21 and the protrusion 21a as well as the stopper groove 13 may occur.
The looseness of the protrusion 21a within the protrusion 21a is also absorbed, and strong fastening is achieved.

To engage and disengage, the male clip 10 is rotated counterclockwise relative to the female clip 20 as viewed in FIG. 1b, and the protrusion 21a is slid in the opposite direction along the grooves 13, 13a.

In addition, in the above-mentioned embodiment, the guide groove 13 is not necessarily orthogonal to the flat back surface 11a;
Also, it does not have to be a straight line. The elastic guide surface 13c is
Alternatively, an elastic body may be bonded. It is also possible to eliminate the elastic part 22 and instead form it in an annular shape on the flat back surface 11a. The pawl 13d can be eliminated or the stopper groove 1 can be removed to the extent that the play of the elastic part 22 can be absorbed.
The upper surface of 3a may be inclined upward in the depth direction. Furthermore, the male clip can be integrally formed into a plate shape to be fastened, and only the female clip can be prepared separately. In this case, the plate-like body also serves as the head part of the oscrip.

[Effect of idea]

As described above, according to the present invention, it is possible to realize an inexpensive clip that can be easily set without tools and that can fasten plate-like objects without play.
