Description

[Detailed Description of the Invention] The present invention relates to a button fastening device useful for fastening a plurality of sieve plates and the like.

Previously, similar resin button fasteners were used.

Although it is easy to install and can be removed without damaging the sieve plate, etc., it is not waterproof, and if it is reused, the button fixing device may be deformed or damaged due to removal. , due to these reasons, there were problems with adhesion.The button fastener of the present invention was developed to eliminate these drawbacks, and is a button fastener with excellent waterproofness and reusability. The purpose is to provide

The present invention will be explained below with reference to illustrated embodiments.

The button fastener according to the present invention consists of a main body 10 shown in FIG. 1 and a cap 20 shown in FIG. 3.

These main body 10 and camp 20 are made of resin.

FIG. 2 is a sectional view taken along line 2-2 in FIG. 1. The main body 10 is
It consists of a head 11, a body 12 extending from the lower surface of the head 11, and legs 13 continuous to the body 12.

The body part 12 has through holes 14, 14 arranged in parallel, and on the side of the row of the through holes 14, 14, the circumferential surface of the body part 12 has a semicircular shape with a gentle taper on the upper plane. Protrusion 15
is provided.

The leg portion 13 has a diameter smaller than that of the body portion 12, and a solo bread ball portion 16 is provided approximately at the center thereof, and a stopper 11 is formed circumferentially at the lower portion.

The cap 20 has a cylindrical shape and is formed with a thin wall thickness so that it can easily fit into the main body 10, and has a flange 21 at the upper end.
The upper end portion 22 is formed to be approximately equal to the body portion 12 of the main body 10, and the inner diameter is formed to become smaller from the upper end toward the lower end in a gentle curve or straight line.

Further, the lowermost end portion 23 protrudes inward, and its inner diameter is approximately equal to the leg portion 13.

Further, an engaging portion 24 with which the protrusion 15 of the main body 10 engages is provided inside the cap 20.

Next, the fourth method of using the button fixing device having the above configuration will be explained.
This will be explained using figures.

In FIG. 4, 30 is a panel, 31 is a sieve plate, and a leather 32 is pasted on the surface thereof.

The button fastener according to the present invention is used in a state where the main body 1o and the camp 20 are combined as shown in FIG.

That is. The leg part 13 of the main body 1o is forcibly press-fitted from the upper end part 22 side of the camp 20, and the lowermost end part 23 of the camp 2o is used by positioning it in the small diameter part between the solo bread ball part 16 and the stopper 17.

Thereby, the cap 20 is assembled integrally with the main body 1° due to the presence of the stopper 17.

Therefore, the sieve plate 31 is stacked on the panel 3o, and the main body 10 is pushed into the hole 30a of the panel 3o as shown in the figure.

Next, when the head 11 of the main body 1o is strongly pressed as shown in FIG.
3.

Thereby, the sieve plate 31 is fixed to the panel 3o via the main body 1o and the cap 20.

in this case. Since the top and bottom of the solo bread ball part 16 are tapered, the lowest end 23 can easily cross over the solo bread ball part 16, and the presence of the solo bread ball part 16 gives a sense of moderation when pushing the cap 20. be able to.

Moreover, since the body 12 of the main body 10 is inserted while being elastically narrowed by the presence of the through hole 14, the main body 1o can be easily inserted.

In addition, the lowermost end 23 is the upper leg portion 13 of the solo bread ball portion 16.
When engaged, the lowermost end 23 comes into close contact with the leg 13, and the elasticity of the body 12 pushes the cap 20 outward and makes it come into close contact with the inner periphery of the panel hole 30a of the panel 30. Excellent preventive properties.

Furthermore, since the protrusion 15 of the main body 10 engages with the inner diameter portion of the cap 20 and expands the outer circumference of the camp 20 outward, the panel 3
0, the camp 20 is less likely to fall off easily and can be securely attached.

Further, the button fixing device is removed by peeling off the end portion of the sieve plate 31 while remaining attached to the sieve plate 31.

At this time, the camp 20 is removed in the state before the button fastener is first inserted.

That is, the protrusion 15 has come off from the engaging portion 24 of the cap 20.

The button fastener removed in this way is attached to the cap 2.
Since it can be removed without any damage due to the elastic action of 0, its performance will not deteriorate even after one reuse.

As is clear from the above description, the button fastener according to the present invention is easy to install and remove, and has excellent waterproof properties and reusability.
