Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a buckle, a buckle used for folding a belt, a tape, a string, a rope, a hook-and-loop fastener belt (hereinafter referred to as a belt, etc.), and a material that is subjected to a load due to tying or pulling. It is about.

[0002]

[Prior art]

 Conventionally, a plurality of portions of a metal rod-shaped member as shown in FIG. 3 are bent or curved to abut or fix both ends of the rod-shaped member to form an annular body such as a circle, a square, a D-shape, etc. The term "annular" in the above refers to an endless shape including these shapes.) The buckle which has become widely known.

[0003]

[Problems to be solved by the invention]

 The above-mentioned conventional buckle is easily deformed when an excessive load is applied, and once deformed, it is hard to restore because it is hard, and even when restored, the strength is significantly reduced due to the previous deformation. Not only that, even when the buckle is used for a long time without being deformed, the connecting and fixing means that is always connected and fixed to the buckle may be cut off at a contact portion with the buckle.

Furthermore, when a hook-and-loop fastener is used for the purpose of fastening, if the hook-and-loop fastener is tightly closed at the time of adjustment, the buckle transmits the hook to the hook-and-loop fastener without relaxing external impact. A slight external pressure or temporary load in the pulling direction could cause the hook-and-loop fastener to come off.

[0005] The present invention has been made in view of the above-described problems, and eliminates a drawback that the buckle is practically impaired in the tightening function due to deformation of the buckle. It is an object of the present invention to solve the problem of preventing the belt from being disengaged by improving durability against external pressure and the like when used for tightening.

DESCRIPTION OF THE PREFERRED EMBODIMENTS AND

【Example】

 The buckle in the embodiment of the present invention is a colorless and transparent two-piece stainless steel wire (4) with a resin property of 1.3 mm in diameter and about 6 cm in length, which is coated with vinyl chloride and has resilience by the physical properties of a spring. After passing through a protective tube (3) made of pure vinyl chloride, both ends of the wire (4) are joined by a brass cylindrical caulking (2) shorter than the protective tube (3) to form an annular shape. The buckle is characterized in that the tubular caulking (2) is held by the protective tube (3) and the other protective tube (3) is arranged at the opposite position on the same ring of the wire (4). .

The annular wire (4) is formed into an ellipse as shown in FIG. 1 so as to press both ends of the protective tube (3) and the inner wall at the center, and to press both ends of the protective tube (30) from outside. The contact not only prevents the protective tube (3) from being inadvertently displaced, but also reduces the load in the pulling direction and improves the strength of the buckle (1).

In the embodiment, as the resilient metal wire, a metal wire such as a spring wire having a spring property using a stainless steel wire can be used. It is made of colorless and transparent vinyl chloride, but is not limited to this.The color does not need to be particularly transparent, and the material can be implemented by using other synthetic resins such as urethane or synthetic rubber. Needless to say.

In the resin coating, the coating with vinyl chloride is performed, but the coating is not limited thereto, and the coating may be performed with another synthetic resin such as urethane.

Further, a similar effect can be obtained by winding a band or the like around a tubular caulking portion of the buckle (1) instead of the protective tube (3). In this case, the band or the like may have no adhesive force, and the final end of the winding (not shown) may be attached by means such as welding.

Further, in the case where a conventional polygonal buckle is used instead of the conventional buckle, it is very easy to pass three or more protective tubes (3) through a metal wire. .

[0013] In order to prevent the protective tube (3) from being displaced or being stretched by a sudden load on the wire (4), etc., the protective tube ends (30) are prevented from cracking or being damaged. The part (30) may be subjected to reinforcement processing by embossing, or another reinforcement member may be attached to the part (30).

In addition to the above, for example, it is extremely easy to make the protective tube (3) have substantially the same length as the wire (4) and cover the entire wire (4) with the protective tube (3). Needless to say. However, in such a case, since the wire will not be exposed, there is no danger of touching with the hand, etc., taking into account the wear of the inner surface of the protective tube (3) due to the wire and the economics of resin coating. Then, it is also possible to carry out without performing the resin coating.

Next, as shown in FIG. 2, a description will be given of a case where the above-described embodiment of the present invention is used as a buckle of athletic shoes (4).

The sports shoe (5) using the buckle (1) according to the embodiment of the present invention is formed by connecting the protection tube (3) of the buckle (1) to the ring-shaped portion by forming the tip into a ring shape. The outer surface of the athletic shoe (5) is provided with three fixing bands (50) as fixing means, and is fastened by the same number of surface fastener belts (51) provided on the inner surface side correspondingly. It is an athletic shoe characterized by performing.

Here, one of the protective tubes (3) is held by the fixing band (50), and after passing the tip of the hook-and-loop fastener (51) through the buckle (1), it is folded back and overlapped. It is what you wear. The hook-and-loop fastener belt (51) uses a self-contained fastener in which male and female engaging elements are mixed on an engaging surface.

The athletic shoe (5) described above uses the buckle (1) of the present invention so that even if an excessive load is applied to the buckle (1), the annular wire (4) can be used. The buckle can be prevented from becoming unusable due to the elastic deformation.

Further, even after long-term use, the protective tube (3) can prevent the surface fastener belt (51) and the fixing band (50) from being worn or cut.

Furthermore, even when wearing sports shoes (5) and tightening the hook-and-loop fastener belt (51) to the full extent, it is possible to reduce external impacts and the like, so that the hook-and-loop fastener belt (51) comes off. Not only can this be prevented, but also the burden on the foot or the entire shoe can be reduced.

The present invention can also be used for clothes or other things worn on the human body, such as suspenders and belts, and other daily necessities such as bag buckles.

Further, it goes without saying that these articles can also achieve the same effect as the buckle of the athletic shoes described above, that is, the maintenance of the tightening force and the reduction of the load on the mounting portion and the like.

[0023]

[Effect of the invention]

 According to the present invention, the fastening force can be always maintained by the tension of the metal wire at the time of fixing, and when an excessive load is applied, the above-mentioned excessive load is provided by the play of the metal wire. By absorbing, it is possible to prevent the surface tape belt or the like from coming off.

Further, by providing the protection tube, it is possible to prevent the belt and the like and the connecting and fixing means from being worn by the metal wire.

In addition, by providing the protective tube, the frictional resistance against the belt or the like that comes into contact during use can be increased to make the belt less slippery than the conventional buckle. It is easy to fix when mounting, and it is possible to prevent the tightening part from loosening during use.

Further, by making the protective tube soft, not only the elasticity of the buckle can be maintained, but also the load on the connecting and fixing means abutting on the protective tube can be reduced.

Further, by applying a resin coating to the metal wire, wear of the protective tube can be reduced, and a finger or the like can be prevented from being damaged by the metal wire, and decorativeness can be improved by coloring coating or the like. Can also be planned.
