Description

[Detailed Description of the Invention] The present invention relates to a belt buckle for use in clothing, pole-mounted safety belts, packing, stockpiling, and other uses.

Various buckles have been proposed for these uses. Among these buckles, the structures shown in FIGS. 1 and 2 are known as buckles that can withstand large loads, especially for use in columnar safety belts and the like. In this device, a slider 2 is fitted to the substrate 1 so as to be slidable back and forth, and the slider 2 is fitted with the substrate 1.
The attachment member 3 is inserted into the back side of the belt, and the structure is complicated as it consists of three members, and the parts are separated when the belt 13 is not inserted, making it easy to lose parts. It had

The present invention was devised in view of the above circumstances, and it is an object of the present invention to provide a buckle that has a reduced number of parts, is strong, and can be provided at low cost.

3 and 4 show a buckle according to an embodiment of the present invention, and this buckle consists of two parts: a base plate 1 and a slider 2. FIG. The substrate 1 has side edges 4 on both sides thereof, and between the side edges 4 there are four bridging pieces 5, 6, 7, 8 from the rear to the front. The frontmost bridging piece 8 has a bent portion 9 at its rear end. The slider 2 has an upper plate 10 that is placed on the surface of the substrate 1. Both sides of the upper plate 10 are folded downward and their edges are brought together to form a lower plate 11. It is formed into a flat cylindrical shape. The front end edge of the upper plate 10 faces the bent portion 9 of the substrate 1, and a sandwiching edge 12 with unevenness is formed between the front edge and the bent portion 9 so as to sandwich the belt.

Further, the rear end portion of the lower plate 11 is bent downward.

In the present invention, the substrate 1 is inserted into the slider 2 so as to be able to slide back and forth,
The rear end edge of the bent portion 9 and the clamping edge 12 are opposed to each other.

Reference numeral 13 denotes a belt, one end 13a of which is wound around the second bridging piece 6 from the rear of the substrate 1 and sewn. The free end 13b of the belt 13 is inserted upward from the rear of the lower plate 11 of the slider 2, passing between the clamping edge 12 and the bent portion 9 of the substrate 1, and passing through the upper plate 10 of the slider 2. It is wound around the upper part, passes in front of the bridging piece 5 at the rearmost part, and is pulled out again so as to overlap above the belt 13a on the one end side.

Since the present invention consists of the above configuration,
Consisting of only two parts with a simple shape, the structure is simple and can be provided at an extremely low cost. In addition, in the buckle of the present invention, by sliding the slider 2 backward, the belt 13b
can be moved freely in any direction,
Adjusting the length is extremely easy. Moreover, belt 1
When a large load is applied to the belt 13b, the slider 2 is slid forward by the tensile force of the belt 13b, and the belt 13b is moved between the clamping edge 12 and the rear end edge of the bent portion 9. Belt 13 while holding
This prevents b from slipping and supports the load safely.

In addition, in the present invention, since the bent portion 9 is formed on the bridging piece 8 at the frontmost portion of the substrate 1, the bent portion 9 and the sandwiching edge 12 of the slider 2 are opposed to each other, and therebetween, Clamp the belt 13b. Therefore, even when a large force is applied to the belt,
The belt 13b is simply compressed between the bridging piece 8 and the slider 2, and no shearing force is applied, so the belt is not damaged or cut, and a large force can be applied effectively. can be supported.

Further, since the rear end portion of the lower plate 11 of the slider 2 is bent downward, the insertion opening for inserting the belt 13 is large and easy to pass through. In addition, if a large force is applied to the belt 13 during use, the bridging piece 8 at the forefront of the board 1 will have a bent portion 9.
As a result, a diagonally forward and downward force acts, and slider 2
Since a forward and upward force acts on the lower plate 11, the two forces are balanced. Therefore, even a buckle made of simple plates can support large forces without bending or distorting.

In the embodiment shown in the drawings, the substrate 1 is slightly curved so as to convex upward, but this is to make it conform to the curved surface of the adherend for use in applications such as clothing. It does not necessarily have to be curved; it can be straight or curved.

Claims (1)

[Scope of utility model registration request] It consists of a substrate and a slider slidably attached to the substrate, the substrate has a pair of side edges on both sides, and four bridging pieces are formed between the side edges. The rear end of the frontmost bridging piece is bent upward, and the slider folds both sides of the upper plate downward and butts them to form a lower plate, making it cylindrical. Bend the rear end downward and insert the board slidably into the cylindrical slider, and make the front edge of the upper plate of the slider face the rear edge of the bent part of the board. , one end of the belt is wound and sewn around the second bridging piece from the rear, and the free end of the belt is passed downward from the rear of the lower plate of the slider through the rear of the bridging piece at the frontmost part of the board. The buckle is inserted upward from the top plate of the slider, is turned above the top plate of the slider, passes through the front of the rearmost bridging piece, and is pulled out over one end of the belt.
