Description

[Detailed description of the invention] Industrial application field The present invention relates to a stopper for holding the belt so that it does not loosen after being tightened when an article is tied up with a belt or moored to a fixed object. It is something.

BACKGROUND OF THE INVENTION Many conventional belt fasteners of this type are of a type in which the end portion of the belt is passed through the fastener, similar to the buckle of a bunt in clothing.

Problems that the invention aims to solve However, with such a fastener, when tightening the belt, it is necessary to firmly secure the fastener while pulling the belt through the fastener, resulting in poor operability. .

In addition, a type of stopper that is inserted by folding back the belt is known as described in Japanese Patent Publication No. 36-21375, but this fastener uses the tension of the inserted belt to hold the belt with a cam. Because the belt is pressed down, unless there is a strong tension on the belt, the belt will not be secured at all, and if a strong force is applied to it, the belt will slip a lot and become loose.

This type of belt stopper is used to keep the belt loosely attached to the object at all times, such as car seat belts or infant stroller belts, and then only when the object moves suddenly. There are many uses for securing objects.
However, the stop having the above structure is of no use at all for such applications.

Furthermore, there is a known cam in which the cam is pressed against the belt by spring elasticity, as described in Japanese Utility Model Publication No. 1732/1973, but in this cam, a spring is inserted into a hole formed in the operating member. It is extremely difficult to assemble a belt stopper with this structure.

The present invention was devised in view of the above circumstances, and has a simple structure and can be easily assembled.Also, by folding back the belt and inserting it, the tightening operation is extremely easy. To provide a belt stopper that prevents the belt from slipping carelessly even when the belt is under tension, and that can secure the belt in its original position when tension is applied.

Means for Solving the Problems The present invention provides a main body comprising a pair of side plates facing each other on both sides, and a bottom plate connecting the side plates at the front end of the lower edge of the side plates, at the rear end of the bottom plate. The edge is folded back downward to form a folded part, one end of the belt is attached to the rear end of the main body, a spring pin is inserted into a through hole drilled in the side plate, and a spring pin is provided protruding from one of the through holes. The protrusion is locked in the slit of the spring pin to prevent rotation, and the spring pin rotatably supports a lever member having a cam portion that moves toward and away from the bottom plate when rotated, and one part of the lever member is rotatably supported on the spring pin. A helical spring is housed in a recess formed on the side surface, and one end of the helical spring is engaged with the inner wall of the recess and the other end is engaged with a slit of a spring pin, so that the lever member is moved by the helical spring. The belt is characterized in that the cam part is biased in a direction that contacts the bottom plate, and the belt is held between the cam part and the bottom plate.

The present invention will be explained below with reference to the drawings. 1 is a main body, and 2 and 3 are a pair of side plates provided on both sides of the main body 1 to face each other. A bottom plate 4 connecting the side plates 2 and 3 is formed at the front end of the lower edge of the side plates 2 and 3, and a downwardly folded portion 5 is formed at the rear end of the bottom plate 4. Further, the rear ends of the lower edges of the side plates 2 and 3 are connected by a bridging piece 6, and one end of a belt 7 is sewn to the bridging piece 6. Through holes 8 and 9 are formed in the side plates 2 and 3, respectively, and a protrusion 10 is provided protruding from the inner periphery of one of the through holes 8.

Reference numeral 11 denotes a spring pin, which has a slit 12 formed along its length, and through holes 8 and 9.
The protrusion 10 is inserted into the slit 12, and is fitted into the main body 1 so as not to rotate.

Reference numeral 13 denotes a lever member, which has a through hole 14 in its center, into which the spring pin 11 is inserted, and is rotatably supported around the spring pin 11 as an axis. One side of the through hole 14 expands to form a substantially water droplet shaped recess 15 . Further, a plate-shaped lever portion 16 extends rearward from the central portion, and a cam portion 17 having unevenness is provided at the lower front portion.
is formed, and the cam portion 17 is connected to the lever member 1.
By rotating 3, it is possible to move into and out of contact with the bottom plate 4.

Reference numeral 18 denotes a helical spring, which is housed in the recess 15 of the lever member 13, and the spring pin 11 is inserted through the center thereof. One end 19 of the helical spring 18 is engaged with the inner wall of the recess 15, and the other end 20 is engaged with the slit 12 of the spring pin 11. It is biased in the direction of approaching.

Function To assemble the belt stopper of the present invention,
The helical spring 18 is housed in the recess 15 of the lever member 13, and the lever member 13 is attached to the side plate 2 of the main body 1.
3, and insert the spring pin 1 through the through holes 8 and 9 of the side plates 2 and 3 and the through hole 14 of the lever member 13.
1, the end 20 of the helical spring 18 is locked in the slit 12 of the spring pin 11 in the middle of the insertion, and in this state, the spring pin 11 is rotated by a predetermined angle to give twist to the helical spring 18. Further, insert the spring pin 11 into the slit and insert the protrusion 10 into the slit.
is locked to prevent the spring pin 11 from rotating.

When using the belt stopper of the present invention, the tip of the belt 21 extending from the front is folded upward at the rear edge of the bottom plate 4, and is pulled out forward through the gap between the bottom plate 4 and the cam part 17. . The belt 21 can be tightened by pulling the front end 21a of the belt 21 forward. When tension is applied to the main body side 21b of the belt 21, the lever member 13 is rotated clockwise in FIG. The belt 21 is biased clockwise, and the belt 21 is strongly pressed between the cam portion 17 and the bottom plate 4, so that it will not loosen.

Furthermore, when the lever portion 16 of the lever member 13 is pushed downward, the lever member 13 rotates counterclockwise against the elasticity of the helical spring 18 to release the clamping pressure on the belt 21, so that the belt 21 cannot be loosened. It becomes possible.

Effects of the invention The belt stopper of the invention has belt 7 and belt 2.
By configuring the main body side of 1 with one continuous belt, it can be used for fastening articles.
In addition, by providing a locking metal fitting at each other end, it can be used to anchor an article to a fixed object, and the belt can be effectively prevented from loosening after being tightened strongly. In addition, it is possible to loosen the belt with a simple operation, and the structure is simple, the number of parts is small, the assembly is easy, and the belt can be provided at low cost.

Also, when tightening the belt, use the belt 21
The operation is particularly easy because the stopper can be tightened with one hand by pulling the terminal side 21a of the stopper without supporting it in any way. Furthermore, even in applications such as seat belts and baby carriage belts, where the belt is used without applying much tension at all times, the lever member 13 uses a spring means to pinch the belt 21, so that tension is applied to the belt. In this case, the tension of the belt applies a force to the lever member 13 in the direction of pinching the belt, and the belt is immediately pinched and supported between the cam part 17 and the bottom plate 4 without slipping at all. .

Further, in the present invention, since the rear end of the bottom plate 4 is folded back downward, the belt will not be damaged when tightening or loosening the belt, and will move smoothly.
