Description

[Detailed description of the invention] This invention relates to a buckle for tightening luggage, books, etc. with a band.

A buckle for a tightening band consists of a substantially rectangular frame body and two almost parallel spanning rods spanning the opposite front and rear sides of the frame body, with one end of both the spanning rods being able to bend freely. It is constructed by being connected to the rear side of.

Then, the operation of inserting the band into the buckle and tightening the buckle involves, for example, folding back the end of the band that will become the fastening part to form a loop, inserting this loop-shaped end from the bottom to the top of the frame, and protruding the loop. By hooking the connecting rod to the shaped end and pulling it back, the connecting rod comes into contact with the frame with the band interposed,
The band and buckle are tightened by the resistance between the band, the connecting rod, and the frame, thereby tightening the band.

By the way, since the conventional connecting rod has a restoring force in the direction away from the frame, one loop-shaped end of one connecting rod band is hooked, and then the other loop is attached to the other connecting rod band. During the operation of hooking the loop-shaped end, one of the span-rods must be pressed against the frame by hand to prevent it from coming out from the loop-shaped end due to restoring force. It won't happen.

Therefore, hooking the other connecting rod must be done with one hand, which is very difficult to do.

This invention provides a buckle that prevents the connecting rod from being pulled out from the looped end by hooking the connecting rod onto the looped end of the belt and then locking it to the frame. be.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in FIG. 1, the buckle A of this invention includes a frame 1 having a substantially rectangular ring shape, and opposing front and rear sides 1a and 1 of this frame 1.
It is composed of two almost parallel spanning rods 2 that span b.

One end of the connecting rod 2 is connected to the rear side 1b of the frame 1 via a bendable connecting portion 3, and the elasticity of this connecting portion 3 usually allows the connecting rod 2 to be moved to some extent from the frame 1. It is maintained in the state.

The degree of separation is appropriately set in consideration of the extent to which the belt B does not interfere with the insertion of the belt B into the frame body 1.

Further, both the connecting rods 2 are connected so as to be located on the inner edges of the frame body 1 rather than directly above the left and right sides IC and ld.

Note that, as shown in FIG. 1, if the shape of the connecting portion 3 is a trapezoid with the oblique side facing inward, it is possible to prevent the spanning rod 2 from swinging in the left-right direction when bent.

By being able to prevent this shaking, the connecting rod 2, which will be described later,
It is possible to smoothly fit the protrusion into the groove and the protrusion into the hole.

The side of the frame 1 on which the connecting rod 2 is applied has the connecting rod 2.
Grooves 4 in the left and right sides IC and ld direction into which the IC and LD are fitted are formed.

This groove 4 does not necessarily need to be formed.

A projection 5 is provided on the other end of the connecting rod 2 on the side of the frame 1, and a hole 6 into which the projection 5 fits is formed in the front side 1a of the frame 1.

The protrusion 5 is fitted into the hole 6 with a certain degree of fitting force, and after the protrusion 5 is fitted, the connecting rod 2 does not stand up due to the elasticity of the connecting portion 3.

For example, if the diameters of the protrusion 5 and the hole 6 are approximately the same, a fitting force can be obtained.

The buckle of this invention is constructed as described above, and the operation of inserting the band into the buckle and tightening it will be explained next.

For example, as shown in Figures 2 and 3, when tightening a box C with a band B, the end of the band B wound around the box C, which will become the tightening part, is folded back to form a loop. ,
This loop-shaped end is inserted from the bottom to the top of the frame 1, and the left and right spanning rods 2 are hooked on the protruding loop-shaped ends in order and pulled back, and the protrusion 5 is fitted into the hole 6 and passed. Rod 2
is brought into contact with the frame 1 through the band B, and the band B is tightened.

Due to this fitting of the protrusion 5 into the hole 6, the spanning rod 2 does not stand up and does not come out from the loop-shaped end of the band B.

Therefore, since the other connecting rod 2 can be hooked with both hands, the workability is very good and the band B can be firmly tightened.

Furthermore, since the spanning rod 2 is fitted into the groove 4, the sliding resistance between the band B and the frame 1 increases, and the band is tightened even more firmly.

As shown in the figure, a hole 6 is made to pass through the upper and lower surfaces of the frame 1, and a pair of protrusions 5 that fit into the respective holes 6 from both the upper and lower surfaces of the frame 1 are provided on the spanning rod 2. If so, the span rod 2 can be applied to either the upper or lower surface of the frame 1 to tighten it, and the effects of this invention can also be obtained.

Further, in the above embodiment, the protrusions 5 are provided on both of the extending rods 2, but the protrusions 5 are provided on only one of the extending rods 2, and the extending rod 2 provided with the protrusions 5 is connected to the loop-shaped end of the band B. The above effect can also be obtained by hooking it to the

As described above, according to the buckle of this invention, the connecting rod can be locked to the frame body, and after the connecting rod is hooked to the end of the band, it can be prevented from standing up. Since the connecting rod does not come out from the band, you can hook one connecting rod to the band and then hook the other connecting rod with both hands, making the work very easy.

In addition, after the protrusion is fitted into the hole, the fitting force prevents the restoring force of the spanning rod and maintains the pressure contact of the spanning rod to the frame, making it more effective than conventional ones. It also has the effect of making tightening even stronger.

Furthermore, a protrusion that fits into the hole formed on the top and bottom of the front side of the frame is provided on the top and bottom surfaces of the other end of the connecting rod, so you can apply the connecting rod to either the top or bottom of the frame and tighten it. can do.
