Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener for detachably locking various bands such as a band for a pet mooring device.

[0002]

2. Description of the Related Art In a band fastener of a type in which one end of a band is inserted and clamped, conventionally, as shown in FIG. 5, a lower fastener b is rotated around an upper fastener a by a pair of shafts c and c. There is known a structure in which the band is freely attached to a shaft and one end of a band is clamped between a rectangular plate-shaped portion d of the lower fastener b and the upper fastener a to be locked.

An opening e is inserted through the other end of the band and locked by sewing or the like.

[0004]

However, in the conventional band fastener, the force for holding and holding the band is insufficient, so that the band holding portion is loosened or the band comes off. there were.

[0005] It is an object of the present invention to solve these problems and to provide a band fastener that does not loosen a band clamping portion.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a band fastener of a type in which one end of a band is inserted into a fastener and clamped. An upper fastener for inserting one end into the back side, and a lower fastener rotatably pivotally attached to the upper fastener and pressing one end of the band against the back side of the upper fastener to clamp the lower part, Fasteners,
A lower body having a pressing body which is bent from the main body of the lower fastener in a substantially L-shape, and wherein the upper fastener has a portion on the back side of the upper fastener which presses one end of the band by the pressing body and sandwiches the band; To
It is characterized in that a horizontally long narrow groove is provided.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a band fastener of the present invention will be described with reference to FIGS.

FIG. 1 is a perspective view showing a use state of a band fastener 1 of the present invention, in which an upper fastener 2 and a lower fastener 3 sandwich one end 4 of a flexible band. Stopped.

Reference numeral 4 'denotes another end of the band. or,
2 and 3 show details of the upper fastener 2 and the lower fastener 3, respectively.

The upper fastener 2 is made of a metal plate. The upper fastener main body 2a has a rectangular shape, and both sides of the upper fastener main body 2a are bent downward to protrude, and are pivotally connected to the lower fastener 3. And a pair of bearing portions 2b, 2b are formed.

Immediately above the shaft cores of these bearings 2b, 2b, a horizontally elongated narrow groove 2c is formed in the shape of a horizontally elongated hole passing through the upper fastener 2. The width of the narrow groove 2c is formed to a size obtained by adding the thickness of the one end 4 of the band and the thickness of the pressing body 3b described later, and the groove length of the lateral groove 2c is: The upper fastener main body 2a is formed so as to fill the width so as to be slightly wider than the lateral width of the one end 4 of the band.

Reference numeral 2d is an opening for inserting and engaging the other end 4 'of the band.

Next, the lower fastener 3 is also made of a metal plate. One end of the lower fastener main body 3a is bent into an L-shape to project a rectangular pressing body 3b. A pair of shafts 3c, 3c protrude from both sides.

The lower fastener 3 includes a pair of shafts 3c, 3c.
The lower fastener 3 is rotatable with respect to the upper fastener 2 because the lower fastener 3 is pivotally mounted on the pair of bearings 2b, 2b of the upper fastener 2.

When one end 4 of the band is pressed against the upper fastener 2 by the pressing body 3b, the pressing body 3b
3d and a narrow groove 2c installed in the upper fastener 2
Are formed so as to be located just opposite each other via one end 4 of the band.

The gap between the distal end 3d of the pressing body 3b and the narrow groove 2c of the upper fastener 2 is formed at one end 4 of the band.
Is formed to be slightly smaller than the thickness.

Next, the method of use and operation of the first embodiment will be described.

When the one end 4 of the band is inserted into the band fastener 1, the lower fastener 3 is rotated to widen the gap between the pressing body 3b and the upper fastener 2, and the one end of the band is rotated. The part 4 is inserted between them.

Next, the lower fastener 3 is rotated so that the pressing body 3b clamps one end portion 4 of the band so as to press the upper fastener 2 as shown in FIG. Part 4
A part of the back of the band rises in the narrow groove 2c provided in the upper fastener 2 to have a wedge shape A, so that one end 4 of the band comes off the band fastener 1 or is pinched. There is no worry about loosening.

In the first embodiment, the upper fastener 2
The installed narrow groove 2c penetrates the upper fastener 2 and is formed in a horizontally elongated hole shape. This is because the narrow groove 2c does not penetrate the upper fastener 2 and is formed in a shallow groove shape with a bottom. Is also good.

[0021]

As described above, according to the present invention, it is possible to provide a band fastener which does not loosen the band clamping portion or come off the band.
