Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a novel structure of a buckle in a clothing band, and particularly relates to an engagement protrusion that engages with an engagement hole drilled in a band body. This invention relates to an improvement of a buckle for a band having a protruding type.

In general, this type of buckle simply has an engaging protrusion protruding from the back surface of a plate constituting the buckle. However, with this type of buckle, the length of the band cannot be finely adjusted, and the band does not press strongly against the abdomen when the patient is full after a meal.

BACKGROUND ART Therefore, in this type of band, one has been devised in which the length of the band can be expanded and contracted by the action of a spring means, thereby making it possible to finely adjust the length of the band. FIG. 3 shows an example of this type of buckle.

Sliding member 2 that can freely slide back and forth on buckle body 1
is provided, one end of the band 4 is fixed to the sliding member 2, and an engagement protrusion 3 is provided at the tip of the buckle main body 1 to engage with an engagement hole 5 formed in the other end of the band 4. The sliding member 2 is biased toward the front of the buckle body 1 by a spring means 6.

When the buckle is worn, the sliding member 2 is in the front position of the buckle main body 1 and the band is in a contracted state, but when the stomach is full, the band 4 is pulled and the sliding member 2 is in a contracted state. The movable member 2 moves to the rear position of the buckle body 1 against the elasticity of the spring means 6, and the band stretches by that amount. Therefore, the wearer's abdomen is not excessively tightened.

Problems to be solved by the invention However, in the conventional example, band 4
The fixing part to the sliding member at one end has many parts and must be extremely complicated. If only the structure is considered, one with a simple structure can be used, but the size of the buckle becomes large, which is not preferable.

Further, since the band 4 is provided on the sliding member 2, it swings relative to the buckle body 1, and the band 4
It has a disadvantage that the side edges of the buckle body 1 rub against the buckle body 1 and are easily damaged.

Moreover, since the spring means 6 is provided in front of the sliding member 2 and acts as a tension spring, the spring means 6 easily yields and has poor durability.
Since the width of the buckle body 1 is large, it is necessary to provide the spring means 6 on both sides of the buckle body 1.
has no choice but to be approximately rectangular, which imposes design constraints.

The present invention was devised in view of these circumstances, and has a simple structure, a small number of parts, the band does not get scratched by rubbing, it is highly durable, and there are few restrictions in terms of design. The purpose of this invention is to provide an excellent buckle for a band.

Means for Solving the Problems The present invention provides a buckle that is fixed to one end of a band body and has an engagement protrusion that engages with an engagement hole drilled in the other end of the band body. A band clamping member is provided on the buckle main body constituting the outer shell of the buckle, and a sliding member having an engaging protrusion protrudingly provided inside the buckle main body is provided so as to be slidable back and forth with respect to the buckle main body, and the engaging protrusion protrudes from the back surface of the buckle body, and the sliding member is always biased rearward with respect to the buckle body by spring means.

1 and 2 show the buckle of the present invention. Reference numeral 1 denotes a buckle body constituting the outer shell of the buckle, and a band holding member 7 is provided at the rear of the buckle body.
is provided, and one end of the band 4 is firmly fixed by the band holding member 7. A box-shaped portion 8 is formed at the front of the buckle body 1, and the back surface thereof is covered with a back plate 9, and a slit 10 is formed in the center of the back plate 9.

A sliding member 11 is fitted into the box-shaped portion 8 so as to be slidable back and forth relative to the buckle body 1, and its sliding movement toward the rear is restricted by a lid 12. An engagement protrusion 3 that engages with the engagement hole 5 of the band 4 projects from the tip of the back surface of the sliding member 11, and the engagement protrusion 3 projects downward through the slit 10. Thus, the sliding member 11 is always biased rearward within the box-shaped portion 8 by the spring means 6.

Function: The buckle of the present invention is worn by wrapping the band 4 around the wearer's torso and engaging the engagement protrusion 3 of the buckle with the engagement hole 5 formed at the other end of the band 4. do.

When worn normally, the sliding member 11 is biased toward the rear of the box-shaped portion 8 by the elasticity of the spring means 6, and the band is in a shortened state. When a tensile force is applied to the band, such as when the stomach is full, the sliding member 11 is moved by the spring means 6.
The band moves forward by compressing it against the elasticity of the band, thereby increasing the length of the band and preventing excessive pressure on the abdomen.

Effects of the invention In the buckle of the present invention, the buckle body 1
Since the engaging protrusion 3 slides against the buckle, the band holding member 7 is fixed to the buckle body 1 in the same way as conventional buckles, and the structure is simple and the number of parts is small, making it inexpensive. can do. In addition, since the sliding member 11 only needs to slide the engagement protrusion 3, its width can be reduced.
Spring means 6 can also be arranged along the central part of the buckle body 1. Therefore, the width of the front part of the buckle body 1 can be made extremely narrow as shown in the drawings, greatly expanding the range of design options. Furthermore, since the spring means 6 is a compression spring, it does not yield due to excessive deformation and has excellent durability.

Further, according to the present invention, since the band body 4 is directly fixed to the buckle body 1, the band 4 does not swing relative to the buckle body 1 as in the conventional example, and the band 4 is fixed directly to the buckle body 1. This prevents the side edges of the buckle from rubbing against the buckle body 1 and causing damage.

Furthermore, in conventional buckles of this type, the engaging protrusions are integrally fixed to the back side of the buckle body, so the engaging protrusions get in the way when polishing and finishing the back side of the buckle at the end of the buckle manufacturing process. However, according to the present invention, the engaging protrusion 3 is a sliding member 11 that is separate from the buckle body 1.
Since the buckle is provided in the buckle, finishing work is extremely easy and a well-finished buckle can be obtained.
