Description

Detailed Description of the Invention (A) Field of Industrial Use In this utility model, a thin synthetic resin sheet or the like is formed by cutting or the like, and a plastic bag is fastened or an electric appliance cord or the like is tightly bound. At this time, the present invention relates to a binding tool that mainly uses the elastic force at the time of tightening generated by the elasticity of the bound objects.

(B) Conventional technology Conventional binding tools include utility model publication No. 4552 in 1964 (hereinafter referred to as reference (a)) and utility model publication No. 7099 in 1936.
No. (hereinafter referred to as the reference (b)) and the like, in (a), the barb teeth 3 provided on the strap 1 portion, and in (b), the strip 3 portion. Provided,
The wavy concavo-convex portion 4 has a structure in which it is tightened by engaging with the through hole 2 formed in a circular shape and the hole 2 formed in a horizontal shape, respectively. 3,
Further, in the structure shown in (b), a pressing force is applied from the front direction to the wavy concavo-convex portion 4 and the small piece portions of the respective hooking portions at the time of binding.

(C) Problems to be Solved by the Invention In such a conventional technique, it was impossible to use a very inexpensive and thin material. That is, when a thin material is used, the pressing force from the front direction applied to each hooking portion cannot be fully resisted, and in FIG.
However, from the through hole 2, in FIG.
However, the structure is such that the holes 2 are easily separated from each other. It is an object of the present invention to provide an improved binding tool by solving the problems as described above so that the binding can be stabilized even with a very thin material.

(D) Means for Solving Problems The present invention has the following configuration in order to achieve the object.

(A) The engaging piece and the winding piece are integrally formed by a sheet made of a flexible synthetic resin or a thin film-like material having flexibility.

(B) The engaging piece is provided with a slit-shaped long hole in which one of the engaging pieces is obliquely inclined with respect to the horizontal axis.

(C) The inclination direction of the hooking part due to the notch of the winding piece, one of which is inclined obliquely with respect to the horizontal axis, is substantially aligned with the inclination direction of the slit-like long hole of the engaging piece, and the engagement is performed. A winding piece hooking portion is provided on the side of the winding piece on the same side of the slit-shaped elongated hole on the side closer to the oblique upper end and on the same side.

(E) Action Due to the elasticity of the body to be bound, the two hooking portions are pressed against each other mainly by the elastic force generated by the binding during binding.
That is, the slanted upper end portion of the slit-shaped long hole provided in the engagement piece and the slanted lower end portion of the hooking portion provided in the winding piece are hooked in pressure contact with each other. In this way, in order to establish a proper hooking state, there is no natural disengagement except by artificial operation.

(F) Embodiment An embodiment of the present invention will be described with reference to FIGS.

1 and 2 are front views showing an embodiment of the present invention.

Explaining the method of use, the winding piece 1 is rotated around the bundled object 6 to allow the tip of the winding piece 5 to penetrate into the slit-shaped long hole 4, and then the vicinity of the tip of the winding piece is pulled with a fingertip to remove the bundled object 6. After tightening, the winding piece hooking portion 3 provided by cutting the winding piece is hooked on the oblique upper end of the slit-shaped long hole 4.

During this operation, the winding piece is inevitably pressed substantially in the direction of arrow A due to the elastic force of the bundled body, so that as shown by arrow B, the diagonal lower end of the winding piece hooking portion 3 has a slit shape. The slanted upper end of the long hole 4 is hooked in a pressed state. FIG. 2 shows the state of completion of bundling.

When unwinding, follow the reverse procedure described above, that is, pull the winding piece slightly in the direction indicated by arrow C, pull out both hooks, and pull the winding piece somewhat in the direction of arrow D until the upper end. It can be solved in an instant by pulling with your fingertips.

With such a structure, when binding, the slanted upper end of the slit-shaped elongated hole 4 and the slanted lower end of the winding piece hooking portion 3 are pressed against each other, and the direction in which the pressing force is applied is the slit-shaped elongated hole 4.
In this case, it is on the extension line of the oblique upper end, and on the winding piece hooking portion 3, it is on the extension line of the oblique lower end. That is, the direction in which the pressing force generated by tightening and bundling the objects to be bound is the winding piece body portion. Therefore, since the load due to the pressing force is hardly applied in the front direction of the small piece portion of the winding piece hooking portion 3, even if a thin material is used, the same portion cannot be resisted, and there is a fear of spontaneous disengagement due to bending or the like. There is no.

At the time of binding, even if the slit-shaped long holes 4 are obliquely provided, the entire width of the winding piece is bound in a parallel state. That is, the shape of the winding piece does not have a shape like the middle of a right-cone cylinder, but it is possible to completely bind the winding piece with the shape of the slit-shaped long hole 4 by the partial shape of the cylinder. This is because it is provided longer than the width, and further, the length of the winding piece hooking portion 3 due to the cutting of the winding piece causes a difference in the length. As shown in FIG. 2, the winding piece 1 easily penetrates into the opening of the slit-shaped long hole 4 in an oblique state. Therefore, as shown in FIG. It becomes vertical. Therefore, the full width portion of the winding piece is tightened in a parallel state, so that the tightening force is evenly applied to the periphery of the bundle and the binding is completed. In addition, it does not cause any trouble when used, and is within a range of natural fingertip operation, and can be smoothly performed.

(G) Effect of the device (a) As described above, the slit-shaped long hole formed by the insertion hole is provided obliquely with respect to the winding single axis, so that the direction of the pressing force generated by the binding can be controlled by the unique structure. I was able to convert. In both hooking parts (3) and (4),
Since the pressing force is not applied in the front direction of the small piece, but it is applied to the main body part, there is no bending of the small piece part, it is extremely easy to resist, even though using a very thin material, compared to conventional products , It is possible to fulfill the excellent binding function, which is not inferior to win.

(B) With such a structure and action, a thin sheet or a thin film-like material can be used as a material. For example, a material having a thickness of about 0.2 mm can fully exert its function with a reserve capacity. From the point of view, it was possible to expand the range of applicable materials in terms of thickness.

(C) For example, the present invention, which is often used as an accessory for packaging bread and the like, is extremely advantageous in that it can be finished at an extremely low cost because of its thin material.
