Description

[Detailed description of the invention] [Industrial application field] This invention relates to the improvement of buckles used as arm buckles, wrist buckles, etc. More specifically, the buckle is made into a pair of foldable buckle pieces and attached to this buckle. To provide a buckle which allows a belt or the like to be tightened or loosened with one touch by a length corresponding to the length of the pair of buckle pieces.

[Prior art] Buckles used for tightening and locking belts, etc., are usually made by inserting the belt into the buckle and tightening it according to the amount of tightening, and also when the belt is released, the belt is pulled out from the buckle. The amount of slack in the belt is determined by the amount.

Therefore, even when putting on or taking off the belt, it is necessary to insert the belt through the buckle one by one to narrow it down, or to release the locking state and pull out the belt from the buckle.

However, if the belt is a wrist buckle or arm buckle that can be attached or removed within a certain slack width of the belt, the entire width of the belt must be pulled out from the buckle one by one, or tightened within a certain slack width without inserting the belt. , it is considered advantageous to be able to perform a release operation.

Therefore, a typical watch band etc. has a belt of 10
A buckle piece 10 that can be folded freely in the middle of 1,101
2, 103, and 104 are arranged, and are rotatably pivoted to each other, and the buckle pieces 102, 104 are also pivoted to the belts 101, 101 to meet the above requirements.

And in this watch band, buckle piece 102
The tightening amount of the belt during folding of steps 104 to 104 is determined by changing the pivot position of the buckle pieces 102 and 103, and the side plate 102 is attached to the buckle piece 102.
a, 102a are provided, and shaft holes 102b...10 are provided in this.
2b is opened to support the shaft pin of the buckle piece 103, and the actual tightening of the belt is done using the buckle piece 103 that is folded back below the buckle piece 102.
and 104, and the buckle piece 10
The front plate 102 of the buckle piece 102 is secured to a bearing-shaped spherical surface 105 provided at a pivot position between the buckle piece 102 and the belt 101.
c is pushed in to prevent the buckle piece 103 from springing up.

However, such a precedent is based on the buckle piece 10.
2 to 104 are folded and locked together, since the belt 101 is attached to the end of the buckle piece 102 and the end of the buckle piece 104, the attachment position of the belt is adjusted by the length of the buckle piece 102. If more load than necessary is applied to the belt 101, the locking front plate 102c side of the buckle piece 102 tends to lift up.
The locking function of the buckle was not fully satisfactory.

Furthermore, since the metal buckle piece 102 is interposed between the belts 101, 101, the design of the belt is greatly restricted, and it is particularly difficult to simplify the design using a single belt fabric. Ta.

[Purpose and Structure of the Present Invention] In view of the inconveniences in the prior art, the buckle according to the present invention has a folded structure of two buckle pieces, and the tightening adjustment of the belt is performed by adjusting the belt attachment to the buckle piece. In addition to simplifying the structure, the locking positions of the belts are placed next to each other when the buckle is folded and tightened to prevent the buckle pieces from coming out, resulting in a more solid locking. The buckle pieces are firmly connected to each other by means of a locking means provided on the buckle pieces, thereby preventing unexpected release of the buckles. was made as follows.

That is, the buckles used are a pair of buckle pieces 1 and 2 that are pivotally connected so as to be foldable, and the free end of one buckle piece 2 is provided with an attachment ring portion 2b such as a belt 4, and, At the free end of the other buckle piece 1, and on the side where the buckle piece 2 is folded and overlapped, a connecting part 1c is provided in a raised manner, and a belt 3 or the like is inserted through this connecting part 1c. A pair of elongated holes 10, 10 are provided at the front and rear of the connecting rod 9, with the connecting rod 9 interposed therebetween, and the elongated holes 10, 10 are located opposite to the raised side of the connecting portion 1c. The belts 4 and the like are fixed to the mounting ring portion 2b, and the belts 3 and the like are connected to each other in the width direction of the buckle piece 1, and the belts 3 and the like are connected to each other in the width direction of the buckle piece 1. Hole 1
0 and 10 in a removable manner, and is connected to the connecting rod 9. The one buckle piece 2 has an insertion hole 6, and the one buckle piece 2 that is folded and overlapped has an insertion hole 6. The surface of the other buckle piece 1 is provided with a locking protrusion 5 that is inserted into and engaged with the insertion hole 6.

[Example] A typical example of the buckle according to the present invention will be described in detail below.

First, the buckle to be provided is typically a plastic molded product by injection molding in view of moldability, ease of assembly, etc., and consists of a pair of buckle pieces 1 and 2 molded from other materials such as metal.

The buckle piece 1 and the buckle piece 2 are curved on opposite sides through their respective pivot parts, so that when the two are overlapped via the pivot parts, their surfaces come into close contact with each other. It is composed of (Buckle piece 1 and buckle piece 2 may be arranged linearly on the same plane without necessarily being curved.) In the illustrated example, buckle pieces 1 and 2 are molded at the same time by injection molding. The shaft part 2a of the buckle piece 2 is positioned between the bearing parts 1a, 1a of the buckle piece 1, and the shaft 2a of this shaft part 2a
b, 2b are formed in the bearing portions 1a, 1a of the buckle piece 1 by a die-cutting method.

As a result, only one type of buckle is required for forming the buckle, and there is no need to assemble the buckle pieces 1 and 2 to each other, which has the advantage that the buckle forming cost is particularly low. The mutual pivot structure is particularly deep and has the feature of being a robust shaft support structure.

In addition, a step 2c is provided between the shaft portion 2a of the buckle piece 2 and the buckle piece 2 by an amount equivalent to the wall thickness of the buckle piece 1 so that the buckle piece 2 comes into close contact with the buckle piece 1 when folded.
is provided, and the buckle piece 2 is configured to fall into the shaft portion 2a by an amount equivalent to the thickness, and the bearing portion 1 of the buckle piece 1 in the rotating position of the shaft portion 2a
A cutout portion 1b is formed between a and 1a.

Next, a locking protrusion 5 is provided on the curved convex side of the buckle piece 1, and the top of the locking protrusion 5 is formed into a hook portion 5a protruding from the side opposite to the bearing part, thereby promoting elastic deformation of the locking protrusion 5. A slit 7 is provided in the surface of the buckle piece 1 located below the hook portion 5a for the purpose of punching and molding the hook portion 5a.

Further, the buckle piece 2 overlapping with the buckle piece 1 is provided with an insertion hole 6 at a position corresponding to the locking protrusion 5, and the hole 6 is inserted into the locking protrusion 5 except for the hook portion 5a. The concave stepped portion 6a is provided from the curved concave side that the top end comes into contact with toward the convex side, and is expanded on the convex side on the side opposite to the bearing portion.
It is said that

As a result, when the buckle piece 1 is overlapped with the buckle piece 2, the locking protrusion 5 of the buckle piece 1 is inserted into the insertion hole 6.
The hook portion 5a is guided toward the convex side of the hole 6 while causing elastic deformation in the hook portion 5a, so that the hook portion 5a is elastically engaged with the concave stepped portion 6a of the hole 6, and the buckle piece 1 and the buckle This means that the pieces 2 are firmly attached.

Next, a mounting ring portion 2d of the belt 4 is provided so as to float up on the convex side of the free end of the buckle piece 2, and the belt 4 is attached to the ring portion 2d within a gap 8 corresponding to the wall thickness between the ring portion 2d and the buckle piece 2. The winding stops. As a result, when the buckle piece 2 is superimposed on the buckle piece 1, the inconvenience that the belt 4 operates to lift the buckle piece 2 can be avoided.

Furthermore, the connecting portion 1c of the belt 3 is raised in a box shape on the convex side of the buckle piece 1 located laterally than the overlapping buckle pieces 2, and an inverted triangular shape is formed on the upper part of the connecting portion 1c. A pair of elongated holes 10, 10 intersecting each other downward through a connecting rod 9 having a cross section are provided to serve as a winding locking portion for the belt 3. As a result, the belt 3 has the advantage of operating to draw the buckle piece 1 downward.

In addition, since the connecting portion 1c is raised in a box shape and provided on the buckle piece 1, when the buckle piece 2 is folded and stacked in close contact with this buckle piece, the free end side of the front side of the buckle piece 2 In addition, since the connecting portion 1c is positioned, there is an advantage that the free end side of the buckle piece 2 can be prevented from coming into contact with clothing or the like and being lifted.

Note that there are knobs 1 on both sides of the free end of the buckle piece 2.
1 is provided to facilitate lifting and releasing of the buckle piece 2.

Furthermore, the configuration of the mounting portions of the belts 3 and 4 described above may be changed as appropriate depending on the intended use of the belts, and is not limited to the embodiments described above.

In addition, when the buckle mentioned above is made of a plastic molded product, there is no need to assemble it, resulting in a strong pivot structure, and it also has the feature of being made of a single component, and at the same time has corrosion resistance. It is in good condition, the inconvenience of rusting is eliminated, and the shape can be simplified and designs can be created by free coloring, painting, etc.

[Effect of the invention] The buckle according to the invention has the above-mentioned characteristic structure, and the belts 3 and 4 attached to the buckle pieces 1 and 2 are adjusted in advance so that the overall length can be adjusted to the desired length when the buckle is tightened. After inserting this into your arm, etc., tighten the buckle piece 1.
By pressing the buckle piece 2 so as to overlap it, the locking protrusion 5 of the buckle piece 1 is inserted into the hole 6 of the buckle piece 2, and the belt is tightened.

The buckles in such a state are buckle pieces 1 and 2.
They are engaged with each other by the locking protrusion 5, and the load applied to the buckle is directed downward from the pivot line x along which the buckle pieces 1 and 2 are folded and pivoted, as shown by the arrow y. The configuration is such that unexpected release of the buckles from each other is more effectively prevented.

In particular, in the buckle according to the present invention, since the belts 3 and 4 are fastened and fastened by the buckle pieces 1 and 2 at almost adjacent positions, it is difficult to lift these belts 3 and 4 upward until they become approximately straight. The buckle pieces 1 and 2 will not be released even if the buckle pieces 1 and 2 are released, and since the buckle pieces 1 and 2 are usually used on curved surfaces such as arms and wrists, the buckle pieces 1 and 2 will not be released from each other when a load is applied to the belts 3 and 4. It appears that there are hardly any.

Also, the buckle piece 2 is raised due to the impact applied to the buckle pieces 1 and 2 (if a load is applied to the belts 3 and 4, the buckle piece 2 does not come out).
Since this is prevented by the engagement of the locking protrusion 5 with the insertion hole 6, the buckle is prevented from being released not only when the belt is attached, but also when the belt is not attached or used loosely. are doing.

The buckle described above can also be used as a watch band, pouch band, side bag band, etc., and can also be used for ordinary bags, bags, or travel bags. It has the feature of being able to be released.
