Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a telescopic fixing device for suspender belts for pants, skirts, etc., belts for shoulder bags, and other belts.

[Conventional technology]

2. Description of the Related Art Conventionally, for example, a device shown in FIG. 6 or 7 is known as a telescopic fixing device for a suspender belt.

The first telescopic fixing device shown in FIG. Skirt) consists of a pull ring f sewn to the upper edge of the skirt S.

In this first telescopic fixing device, the belt B
One end of the belt B is fixed by being wound around the lower intermediate crosspiece d of the adjuster e from the back side and sewn together, and the other end of the belt B is extended downward and folded back at the tension ring f. , from the back side of the adjuster e, pass between the lower horizontal bar b and the lower intermediate horizontal bar d, pass it to the front side, pass between the upper intermediate horizontal bar c and the upper horizontal bar a, and then enter the back side again. It is sewn together with the upper edge of the side skirt.

In the adjustment tool e, the belt B is folded back at a steep angle by the bent edge g formed to protrude obliquely to the back side from the lower edge of the upper horizontal bar a, and is tensioned with the lower intermediate horizontal bar d. Mutual movement of the belts B is restricted by the frictional force generated when the belts B and the ring f are forced to overlap each other.

In addition, the second telescopic fixing device shown in FIG. h and a movable ring m attached so as to be able to move up and down between the intermediate horizontal crosspiece j.

In this second telescopic fixing device, the belt B
One end of the belt B is fixed by being sewn to the upper edge of the skirt S, and the other end of the belt B is extended upward and passed from the back side of the adjuster k to the front side through between the lower horizontal bar i and the middle horizontal bar j. Then, it is passed between the intermediate horizontal crosspiece j and the movable ring m and put back into the back side, and the movable ring m is wound and folded back, and the loop n as an adjustment allowance hangs downward, and the belt is again put on the back side. They are placed on the back side of the upper horizontal crosspiece h, straddling the intermediate horizontal crosspiece j and the movable ring m in an overlapping state, and are sewn to the upper edge of the skirt on the back side.

In the adjustment tool k, when a tensile force is applied to the belt B, the movable ring m is pressed against the intermediate horizontal crosspiece j, thereby causing the belt B wound around the movable ring m to move toward the intermediate horizontal crosspiece j. Belt B is bent at a sharp angle and sandwiched between the crosspiece j and the triple-stacked belt B is pressed against the intermediate horizontal crosspiece j, and the frictional force generated causes the belt B to
The position is fixed.

[The problem that the idea attempts to solve]

The above-mentioned first conventional elastic fixing device requires two sewing operations: sewing the tension ring f to the skirt S and sewing the end of the belt B to the adjuster e. The problem is that it takes time. In addition, in the second telescopic fixing device, the tension ring f in the first telescopic fixing device can be omitted, but the loop n hangs down on the front surface, which is unsightly. There is a risk that the loop n may get caught on something else and fall down.

Furthermore, in the stretching operation, there is a problem in that fine adjustment is difficult because some frictional force acts on the belt to be adjusted.

This invention was made to solve these conventional problems, and it eliminates the need to sew the tension ring to the attachment target, eliminates the appearance of excess material on the front, and allows the belt to expand and contract. It is an object of the present invention to provide a belt telescopic fixing device that can be easily adjusted and can reliably restrict movement of the belt.

[Means to solve the problem]

In order to achieve the above object, this invention includes a fixing device that restricts the mutual movement of three-layered belts with a part on which a tensile force acts and a loop-shaped adjustment part for expansion and contraction, and A belt extension/retraction fixing device consisting of an annular body that is slidably attached to the part on which the tensile force is applied while being inserted through the belt, and the fixing device has a main body having a width corresponding to the belt, and a belt attached to the main body. It consists of a tightening piece rotatably attached around an axis perpendicular to the length direction of the belt, a window large enough to allow the belt to pass through is formed at one end of the main body, and the tightening piece is attached to a short piece of the main body. The fastening piece is formed into an L-shape with a long piece and a long piece. , and a state in which the pressing force is released.

[Effect]

According to the above configuration, after one end of the belt is fixed to the object to be attached and the other end of the belt is passed through the annular body,
Pass it through between the back of the main body of the fixing device and the tightening piece, take it out from the window to the front side, fold it back to the back side at the upper edge of the fixing device, stack it on the back side of the belt, and insert it again between the tightening piece. , as an adjustment allowance, hang down to the annular body and insert it through this annular body, then fold it upward to arrange it in a loop shape, overlap it three times on the back side of the belt, and use it again as a tightening piece. After passing the belt through the belt, the other end is fixed to the object to be attached, and the belt is tightened by rotating the tightening piece so that the tip edge of the short piece presses against the triple layered belt. Mutual movement will be regulated.

Also, by rotating this tightening piece so that the pressing force is released, the belt that continues from the other end of the belt to the adjustment allowance can be moved between the back of the main body and the tightening piece. After changing the length of the adjustment allowance by moving the annular body along the belt, the belt can be adjusted to the desired length by rotating the tightening piece so that the movement of the belt is restricted again. The belt can be adjusted to expand or contract, and the belt can be maintained at the adjusted length.

〔Example〕

In FIG. 1, the telescopic fixing device is composed of a fixing device 1 and an annular body 2, and by folding the belt B twice by the fixing device 1 and the annular body 2, the belt B In this case, mutual movement between the fixture 1 and the annular body 2 is regulated in a triple-superposed state.

As shown in FIGS. 1 to 3, the fixture 1 consists of a main body 3 and a fastening piece 4, which are formed by cutting and bending a thin plate.
The main body 3 has approximately the same width as the belt B, and has bent edges 3 extending from the left and right edges of the substrate 31 to the back side, which are slightly curved in the width direction so as to be convex toward the front side.
2 is formed in a protruding manner, and a window 311 having approximately the same width as the belt B is formed through the upper end of the substrate 31, and a tightening piece 4 is provided as a shaft in the vertically intermediate portion of the bent edge 32. Supporting through hole 321
is formed.

The fastening piece 4 is bent into an L-shape when viewed from the side, and sawtooth locking teeth 411 are formed on the tip edge of the short piece 41 to correspond to the curved shape on the back surface 312 side of the substrate 31. There is. An operating portion 421 is formed on the distal end side of the long piece 42 by slightly bending it outward, and the long piece 42 and the short piece 4
A protruding shaft 43 is integrally formed on both sides of the boundary with 1 and protrudes outward.

This protruding shaft 43 is inserted into the through hole 321 of the main body 3, so that the tightening piece 4 is in a state (restriction state) and 1 in the same figure.
As shown by the dotted line, the short piece 41 is connected to the back surface 3 of the board.
It is attached to the main body 3 so as to be rotatable about the horizontal axis around the protruding shaft 43 between a state in which it is disposed substantially parallel to the main body 12 (released state).

In the above-mentioned regulation state, as shown in FIG. 2, three layers of belts B ₁ , B ₂ , B ₃ are stacked on top of each other between the locking teeth 411 of the short pieces 41 and the back surface 312 of the substrate.
The position of the through hole 321 and the short piece 4 are such that it presses the belts B ₁ , B ₂ , and B ₃ while digging into the belt.
A protrusion length of 1 is set, which allows the above belt to
The vertical movement of B ₁ , B ₂ , and B ₃ is restricted. Further, by prying the operating part 421 from this restricted state and rotating the inner surface 422 of the long piece in a direction away from the main body 3 (counterclockwise in FIG. 2), the tightening piece 4 reaches the released state, and this released state In this case, a space is formed between the tightening piece 4 and the back surface 312 of the substrate, in which the third layer belt B ₃ can freely move in the vertical direction.

Further, the annular body 2 is formed by bending a thin plate.
It is formed so that the belt B ₁ of the first layer and the belt B ₂ of the second layer can be loosely surrounded in a stacked state.

In the fixture 1 and the annular body 2 configured as described above, the fastening piece 4 of the fixture 1 is first set to the released state (see the dashed line in FIGS. 1 and 2). Then, the belt B, whose one end is sewn to the upper edge of the skirt (object to which the belt is attached), is first inserted through the annular body 2 and extended upward, and then this first layer of belt
After B ₁ passes between the substrate back surface 312 of the fixture 1 and the clamping piece 4, it is brought out from the window 311 to the front side.

Next, the first layer belt _B1 is folded back at the upper edge 313 of the main body 3 and lowered to form the second layer belt B1.
The belt B ₂ becomes the third layer belt B 2 , and this belt B ₂ is stacked on the back side of the first layer belt B ₁ and passed between the tightening pieces 4 again, and then the belt B 2 is again passed through the annular body 2 .
is inserted into the

Then, the second layer belt _B2 is folded back at the lower edge of the annular body 2 and extended upward, thereby forming the third layer belt B2.
This belt B ₃ becomes the second layer belt B 3 , and this belt B ₃ is stacked on the back side of the second layer belt B ₂ and is again passed between the tightening pieces 4 , and after this, the tightening pieces 4 are brought into the restricted state ( (See the solid line in FIGS. 1 and 2) to restrict vertical movement of the belt B.
The other end of the belt B is sewn and fixed to the upper edge of the back side of the skirt S, thereby forming suspenders.

In this state, the upper ends of the first layer belt B ₁ and the second layer belt B ₂ are bent at approximately 180 degrees by the upper edge 313 of the main body 3, and the first layer belt B ₁ , the second layer belt B ₂ and the third layer belt B ₃ are sandwiched between the board back surface 312 by the locking teeth 411 of the tightening piece 4 in a triple layered state. ing. Therefore, the total length of the suspenders should be the length of the belt B minus the expansion/contraction adjustment allowance B ₀ formed by the second and third layer belts B ₂ and B ₃ . This makes it possible to reliably maintain the above state even when a tensile force is applied.

To shorten the suspenders, see Figures 1 and 2.
As shown by the one-dot chain line in the figure, the clamping piece 4 is released, holding the fixture 1 with one hand and pressing down the annular body 2 by the desired length with the other hand, and then releasing the clamping piece 4 again. It should be regulated. In the above-mentioned released state, the third layer belt B ₃ can freely move in the vertical direction, so when the annular body 2 is pushed downward, the third layer belt B ₃ is moved to the first layer.
It goes down as shown by the one-dot chain line in the figure. As a result, the adjustment allowance _B0 becomes longer, and the total length of the suspenders can be reduced by the length of this adjustment allowance _B0 .

Conversely, to extend the suspenders, release the tightening piece 4, pull the belt B above the third layer belt _B3 by the desired length, and then tighten the tightening piece 4 again.
should be made regulated. The annular body 2 is also pulled and raised by half the length by which the belt B is pulled, and the total length of the suspenders can be increased by the amount that the adjustment margin B ₀ is shortened.

In this way, the suspenders can be expanded and contracted easily by simply switching the tightening piece 4 between the restricted state and the released state, and the length of the belt B ₃ can be adjusted while it is free to move. Therefore, even fine adjustments can be made easily and quickly, and the length after the fine adjustment can be reliably maintained by bringing the tightening piece 4 into a regulated state.

In addition, the adjustment allowance B ₀ is arranged on the back side of the belt B, and since they are overlapped with each other by the annular body 2, the appearance from the front side is good.
Furthermore, the front side of the annular body 2 etc. can also be decorated.

In the above embodiment, a locking tooth 411 is formed on the tip edge of the short piece 41 of the tightening piece 4, but the shape of the locking tooth 411 can be changed depending on the material of the belt B, etc. For example, it may be formed simply from the edge of the material itself.

Furthermore, in the above embodiment, instead of the fixture 1 shown in FIG. 3, a fixture 1a having sawtooth-like notches 313a formed on the upper edge of the main body 3 as shown in FIG. 4 may be used. In addition, the tightening piece 4 in the above embodiment
Separately, as shown in FIG.
A fixture 1b may be used in which the movement of the upper end of the second layer belt _B2 is restricted by a. With these, the first layer belt
The position of B ₁ and the second layer belt B ₂ can be fixed more reliably.

[Effect of idea]

According to the belt extendable fixing device of this invention, the work of attaching a tension ring to an object to be worn, such as a pull ring, or sewing the belt to the above-mentioned extendable fixing device itself, which is required in conventional extendable fastening devices, is omitted. In addition, the appearance of the belt is not damaged. In addition, the belt can be expanded and contracted easily and quickly even if it is only a fine adjustment, and the belt can be reliably maintained at the adjusted length.
