Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tightening adjustment tool that is attached to a tightening part of a hat, jumper, etc. and is composed of an adjustment belt and a slider engaged with the adjustment belt. The slider can be automatically locked to the adjustment belt by the force of the spring, and
To provide a tightening adjustment tool in which the engagement part of a slider with respect to an adjustment belt can be operated reliably without being hindered by clothing or other objects, and the slider has a simple configuration.

As is well known, the slider of the tightening adjustment device generally has a handle with a claw pivotably supported on the body.
Alternatively, a stepped horizontal hole is provided in the slider body perpendicular to the guide groove, a locking pin formed to be able to lock with the narrow protrusion of the belt is inserted into the hole, and a locking pin is inserted at both ends of the pin. It is known to have a flange that regulates the range.

The former slider has a window hole opened on the top surface of the slider body that allows the stop claw to operate.
In addition, in the latter case, since the flange of the locking pin protrudes outside the body, part of the adhered material or other objects may get caught in the window hole or flange, resulting in incomplete stopping effect of the slider. There were times when this happened. In addition, in the latter case, in order to prevent the locking pin from coming out of the body, it is necessary to attach flanges to both ends, and to keep the locking pin locked to the adjustment belt, the locking pin's claw must be attached. Since it is formed to press against the top surface of the adjustment belt, the pawl of the locking pin comes into pressure contact with the adjustment belt, which of course makes the pin sliding harder, and since the adjustment belt is made of synthetic resin, it is prone to wear. There were disadvantages such as speeding up the process.

This invention focuses on the above points and has developed a unique tightening adjustment tool.Hereinafter, embodiments of this invention will be described with reference to the drawings.

In Fig. 1, A is an adjustment belt that is fixed to the first attachment C, and B is a slider that is connected to the second attachment D, both of which are molded from synthetic resin. , has a groove 1 in the longitudinal direction in the center of the surface of the strip, a large number of protruding teeth 2 are arranged perpendicularly to the longitudinal direction on both sides of the groove 1, and a groove 1 in the longitudinal direction on the back surface. Two legs 3 are provided protruding in the direction, and the legs 3 are provided intermittently in the longitudinal direction to add flexibility to the adjustment belt A. Next, the slider B is constructed by a combination of the body 4 shown in FIG. 2 and the locking body 14 shown in FIG. Locking body guide grooves 6 and 7 are provided on the back and front sides of the fuselage, which are orthogonal to the adjustment belt guide groove 5. The guide groove 7 on the front side is provided over the entire length between both sides, and the guide groove 6 on the back side is used to guide the adjustment belt from one side. A notch 8 is formed on the opening side of the guide groove 6 to extend through the guide groove 5 to an intermediate portion that does not reach the other side. Recesses 9, 9 are provided at the end portions of the cutout portion 8 and the recesses 9, 9, respectively.
9, and a side part 11 having a notch 8 on the back side of the body 4 is thinly formed so as to be flush with the locking body guide groove 6 on the back side to form an adjustment belt guide groove. 5 and has a step shape, and recesses 12, 12 are provided before and after the step. In addition, 1 in the figure
3 is a hook part.

As shown in FIG. 3, the locking body 14 has a size that fits into the locking body guide groove 6, and is formed in a U-shape in cross section. Recesses 9, 9 of the body 4 are provided at the tips of the opposing inner surfaces of the upper and lower pieces, and are large enough to fit into the notch 8.
Protrusions 16, 16 are provided on the back side of the lower piece to engage with the teeth 2 on both sides of the adjustment belt A.
7 is provided in a protruding manner, and a plate-shaped elastic body 18 is provided in a portion corresponding to the lower piece of the base 15 in a wing-like manner to the left and right, and this elastic body 18 is formed integrally with the base 15. Such a locking body 14 is inserted into the notch 8 of the body 4.
Insert from the side, both protrusions 16, 16 of the locking body 14
are engaged in the recesses 9, 9 in a snap manner over the thick walled portion 10 of the body 4, and the locking body guide grooves 6, 9 of the body 4 are engaged.
A locking body 14 is inserted into the body 7, and both ends of the elastic body 18 are locked in the recesses 12, 12 of the body 4,
When the locking body 14 is biased in the direction of pulling it out from the body 4 and in the biased state, the claw 1
7 and 17 are engaged with the teeth 2 of the adjustment belt A, and when the locking body 14 is pushed deeply into the body 4, the locking body 14
End surface 19 of the locking body guide groove 6 with the tip of the lower piece on the back side
The claw 17 is formed so as to come into contact with and restrict the range in which it can be pushed in, and at this time the claw 17 escapes from between the teeth 2.

Note that the example shown in FIGS. 9 and 10 uses the locking body 1
The elastic body 18 of No. 4 is constituted by a coil spring interposed between the base portion 15 of the locking body 14 and the thick wall portion 10 of the body 4.

Since this invention has the above structure, the locking body 14
When pushed deeply into the body 4 against the elastic body 18, the pawl 17 escapes from between the teeth 2, and the slider B
is slid along the adjustment belt A,
Furthermore, if the pressing force of the locking body 14 is removed, the locking body 14 moves to its original position due to the restoring force of the elastic body 18, and at the same time as the pawl 17 engages between the teeth 2, the meshing state is stabilized. It is to be held as such.

As described above, the tightening adjuster according to the present invention has the following features:
A slider fitted to an adjustment belt having teeth on the front side is composed of a body and a locking body, a claw is provided on the back side of the locking body, and the locking body is attached to the body and perpendicular to the adjustment belt guide groove. Since it is movable within a limited range and the locking body is biased in the direction of pulling out from the body by an elastic body, the slider is automatically engaged with the adjustment belt by the force of the elastic body. In addition, the slider has a simple structure, and the locking part for the adjustment belt is provided inside the body, so there is no risk of objects or other objects getting caught in the locking part. , the function of stopping and canceling the stop of the slider is always performed reliably.
