Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel buckle for a clothing band.

Conventionally, various types of buckles for clothing bands have been commercially available, but those that fasten by inserting a pin into a locking hole drilled in the band are available in one size fits all band length. In the case of a one-size-fits-all buckle, the band is clamped between the buckle body and a clamping member with sharp serrations, so the band is easily damaged. It wasn't.

In addition, many buckles are designed to pinch the band inserted through the buckle by rotating the fastening part of the band with respect to the buckle body, but this method does not depend on the wearer's body shape or clothing condition. Therefore, the angle between the band attachment part and the buckle body changes slightly, and depending on the angle, the band cannot be reliably clamped and may loosen.

The present invention was developed in consideration of the above circumstances, and by clamping the band between two flat surfaces, it is possible to firmly clamp the band without damaging it, and the condition of the wearer's body shape and clothing. The object of the present invention is to provide a new buckle that can be worn in an appropriate state at all times, regardless of the circumstances.

Therefore, in the present invention, one end of the belt is fixed to the bottom plate of the buckle main body, which has a roughly U-shaped cross section, and a presser part bent downward is formed at the front end of the operation plate between the front upper parts of both side plates. The bent part of the operating lever, which has an approximately "L"-shaped cross section, is rotatably supported, and a sliding elongated hole that is long in the front and back and whose rear part is curved upward is bored between the side plates at the rear of the shaft support. , a presser plate is slidably suspended from the tip of the presser portion of the operating lever, and a protrusion protruding from the rear side of the presser plate is slidably fitted into the sliding elongated hole; Another feature is that the presser portion is inclined slightly forward from perpendicular to the bottom plate of the buckle body when the operating lever is in the band-clamping state.

Embodiments of the present invention will be described below with reference to the drawings.
The drawing shows an embodiment of the buckle of the present invention. Reference numeral 1 denotes a buckle main body, in which side plates 2b are erected at the front on both side edges of the bottom plate 1a, making the cross section substantially U-shaped, and side plates 1c are vertically disposed downward at the rear. There is. A band end fixing member 2 is rotatably supported on the side plate 1c, and one end of the band A is fixed thereto. Further, several protrusions 1d are formed on the upper surface of the front end of the bottom plate 1a of the buckle body 1. Furthermore, a bearing hole 1e is bored in the front upper part of the side plate 1b, and behind the bearing hole 1e,
A long sliding hole 1f is formed which is long in the front and back and whose rear part is curved upward in an arc shape.

Reference numeral 3 denotes an operation lever, which has a substantially L-shaped cross section with a presser portion 3b bent downward at the front end of the operation plate 3a, and has an L-shaped cross section on the upper side and the tip side of the presser portion 3b, respectively. Rotating shaft 3c and protrusion 3
d is provided protrudingly. The rotation shaft 3a is rotatably supported in the bearing hole 1e of the buckle body 1.

4 is a presser plate. The holding plate 4 has hanging portions 4b erected on both sides of a clamping plate 4a whose front and rear ends are bent slightly upward, and the through hole 4c formed in the hanging portion 4b is inserted into the above-mentioned operation. Protrusion 3d of lever 3
are fitted in a swingable manner, and the presser plate 4 is swingably suspended from the operating lever 3. Further, a protrusion 4d is provided on the rear side of the presser plate 4, and the protrusion 4d
is slidably fitted into the long sliding hole 1f of the buckle body 1.

When the operating lever 3 is rotated rearward, the holding portion 3b of the operating lever 3 is inclined slightly forward from perpendicular to the bottom plate 1a of the buckle body 1.

When the operation plate 3a of the operation lever 3 is rotated upward, the protrusion 3d of the presser part 3b suspends the presser plate 4 upward, as shown by the chain line in the drawing. The protrusion 4d slides backward along the sliding elongated hole 1f, and the gap between the lower surface of the clamping pressure plate 4a and the upper surface of the bottom plate 1a of the buckle body 1 opens, and the free end of the band can be inserted or removed between them. I can put it out.

Next, when the operation plate 3a is rotated rearward with the free end of the band inserted between the clamping pressure plate 4a and the bottom plate 1a, the presser plate 4 moves to the protrusion 3d, as shown by the solid line in the figure. It descends while suspended from the buckle body 1 and approaches the top surface of the bottom plate 1a of the buckle body 1, and clamps the band A between the bottom surface of the clamping pressure plate 4a and the top surface of the bottom plate 1a, and the band A is pulled out from the buckle. to prevent

According to the present invention, it is possible to fix and release the band simply by rotating the operating lever 3, and the operation is easy. Since the condition of the band does not change, the band will not loosen inadvertently.

Furthermore, since the band A is clamped between the upper surface of the bottom plate 1a of the buckle body 1 and the lower surface of the clamping pressure plate 4a of the presser plate 4, even if the clamping force per unit area is small, A large holding force acts on the band A, and the band A will not be damaged.

Further, according to the present invention, the clamping plate 4a is suspended from the presser part 3b of the operating lever 3, and its rear end slides along the sliding elongated hole 1f, regardless of the rotation angle of the operating lever 3. Since it always moves almost parallel to the bottom plate 1a and has some margin at the fitting part with the sliding elongated hole 1f, it can adapt to slight irregularities of the band A, and the band A
This makes it possible to always align the material exactly and apply soft but firm pressure.

Furthermore, in the present invention, when the band A is clamped, the holding part 3b of the operating lever 3 is inclined slightly forward from the vertical position, so the operating lever 3 is inadvertently rotated upward due to the elasticity of the band A. The clamping pressure will not be released.

Furthermore, as in the embodiment shown in the drawings, the band A
can more reliably prevent slippage. However, these irregularities do not need to be sharply jagged like the pinching parts of conventional buckles, and smooth irregularities are sufficient, so they will not damage the band.
