Abstract

PROBLEM TO BE SOLVED: To provide an adjuster which is simple in structure, can make the number of parts smaller and may be easily manufactured. SOLUTION: This adjuster has guide rails 2 arrayed and provided with projections 1 on the front surfaces, a slide body 3 made insertable with the guide rails 2 in a lateral direction and an operation body 4 made insertable with the guide rails 2 in the lateral direction in the inner side of the slide body 3. The guide rails 2 are lifted by upwardly energizing the operation body 4, by which the slide body 3 is detained to the projections 1 of the guide rails 2. The detention by the projections 1 may be released by depressing the operation body 4 exposed from an aperture 5 disposed in the upper part of the slide body 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjuster capable of adjusting the size of trousers such as waist size.

[0002]

2. Description of the Related Art Conventionally, guide rails have been sewn to the outer surface of the waist portion inside the meeting portion formed at the waist portion of pants, and a slide body has been sewn to the inside waist portion of the meeting portion, and There has been an adjuster that releases the locked state of the slide body and the guide rail by performing the operation, and allows the waist size of the pants to be adjusted.

[0003] However, the conventional adjuster is composed of a complex combination of a synthetic resin component and a metal spring or the like.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention
It is an object to provide an adjuster which has a simple structure, can reduce the number of parts, and can be easily manufactured.

In order to solve the above-mentioned problems, the present invention employs the following technical means.

According to the adjuster of the present invention, the protrusion 1 is provided on the upper surface.
Guide rails 2 arranged in rows, guide rails 2 in the left-right direction
And a control body 4 in which the guide rail 2 can be inserted in the left and right direction inside the slide body 3, and the guide rail 2 is urged upward by urging the control body 4 upward. Lifting, the slide body 3 is locked to the projection 1 of the guide rail 2,
When the operation body 4 exposed from the opening 5 provided on the upper part of the slide body 3 is pressed down, the engagement by the projection 1 can be released.

The elastic piece 1 for urging the operating body 4 upward.
2 may be formed integrally with the slide body 3.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

The adjuster of the present invention has a protrusion 1 on the upper surface.
Guide rails 2 arranged in rows, guide rails 2 in the left-right direction
And a control body 4 in which the guide rail 2 can be inserted in the left and right direction inside the slide body 3, and the guide rail 2 is urged upward by urging the control body 4 upward. Lifting, the slide body 3 is locked to the projection 1 of the guide rail 2,
The lock by the projection 1 can be released by pressing down the operation body 4 exposed from the opening 5 provided on the upper part of the slide body 3.

FIG. 1 is a view of the adjuster as viewed from above, FIG. 2 is a view showing a disassembled state of the slide body 3 and the operating body 4, FIG. 3 is a view of the slide body 3 as viewed from above, and FIG. FIG. 5 is a view of the slide body 3 viewed from the left, and FIG.
FIG. 6 is a view showing a state in which the locking by the projection 1 is released. In this specification, a direction perpendicular to the surface of the guide rail 2 is referred to as a vertical direction.

Each of the guide rail 2, the slide body 3 and the operation body 4 can be made of a suitable synthetic resin.

The guide rail 2 is a strip having an appropriate length and width, and two protrusions 1 are arranged at equal intervals on the upper surface.

The slide body 3 has a left wall 6, a right wall 7, a front wall 8, and a rear wall 9 formed in a rectangular frame shape, and a left hole 10 through which the guide rail 2 is inserted into the left wall 6 and the right wall 7, respectively. A right hole 11 is formed, and an opening 5 from which the operating body 4 is exposed is provided at an upper portion,
The bottom has an elastic piece 12. The elastic piece 12 has an arc shape and is formed integrally with the bottom of the slide body 3.

The front wall 8 and the rear wall 9 are formed with recesses 13 for holding the operation body 4 inside.

The operating body 4 has a rectangular shape sized to fit inside the slide body 3 and has a guide rail 2 in the left-right direction.
The slide body 3 has a through hole 14 at the lower end of the front surface and the rear surface. The operating body 4 is vertically movable within a range in which the protruding portion 15 moves up and down in the concave portion 13.

In this adjuster, the guide rail 2 passes through the left hole 10 of the left wall 6 from the outside of the slide body 3 and then passes through the through hole 14 of the operation body 4, and then passes through the right wall 7 from the inside of the slide body 3. Assembled by passing through the right hole 11.

As described above, this adjuster is composed of only three parts, the guide rail 2, the slide body 3, and the operation body 4, and can be assembled and completed extremely easily.

When the adjuster is attached to the pants, both ends of the guide rail 2 are sewn to the outer surface of the inner waist portion of the meeting portion formed at the waist portion of the pants, and slide on the inner waist portion of the meeting portion. The body 3 is sewn.
The guide rail 2 has the upper surface with the projection 1 facing inward. Since the lower surface of the guide rail 2 is partially exposed to the outside, it is desirable to cover the lower surface of the guide rail 2 with the same kind of material as the pants.

In this adjuster, in a normal state, as shown in FIG. 5, the slide 3 is locked to the projection 1 of the guide rail 2, so that the movement of the slide 3 is restricted.

That is, in a natural state in which no force is applied to the operating body 4 from the outside, the operating body 4 is urged upward by the elastic piece 12 and lifts the guide rail 2 passed through the through hole 14. . As a result, the protrusion 1 of the guide rail 2 abuts on the outer surface of the left wall 6 of the slide body 3 above the left hole 10 or the inner surface of the right wall 7 above the right hole 11. , And cannot move even if the slide body 3 is moved.

When the operating body 4 is pressed down with a finger, the position of the guide rail 2 passing through the through hole 14 is lowered as shown in FIG. 6, and the projection 1 and the left hole 10 of the left wall 6 of the slide body 3 are lowered.
Of the right wall 7 and the inner surface above the right hole 11 of the right wall 7 are released. Therefore, the guide rail 2 can smoothly pass through the left hole 10, the right hole 11, and the through hole 14, and the slide body 3 becomes movable.

Then, the size can be adjusted by moving the slide body 3 while pressing down the operation body 4 with a finger.

The adjuster of the present invention is constructed as described above, has a simple structure, can reduce the number of parts, and can be easily manufactured.
