Description

Technical Field

[0001] The present invention relates to a binding strip for binding a plurality of members.

Background Art

[0002] Conventionally, a binding band composed of a head portion, a band portion, and a tail portion has been used to bind a plurality of members. This binding band winds the band portion around a plurality of members, inserts the tip portions of the tail portion and the band portion into the head portion, and binds the band portion to the head portion to bind the plurality of members.

[0003] In such a binding band, in order to finely adjust the length at the time of fastening the band portion and strengthen the fastening force by the head portion (buckle portion), serrated engaging tooth rows 15, 16 shifted by half a pitch are formed on both the front and back surfaces of the band portion 12, and engaging claws 25, 26 shifted by half a pitch are formed on the front and back inner surfaces of the insertion hole 13 of the head portion (buckle portion) 10. A binding band M is known (see Patent Document 1).

Problems to be Solved by the Invention

[0005] According to the binding band M described in Patent Document 1, since the engaging tooth rows 15, 16 of the band portion 12 are formed by shifting by half a pitch, the length at the time of fastening the band portion 12 can be finely adjusted, and since the engaging claws 25, 26 of the head portion (buckle portion) 10 are formed by shifting by half a pitch, the engaging teeth 15a, 16a and the engaging claws 25, 26 can be surely engaged, the movement of the band portion 12 can be blocked, and the fastening force by the head portion (buckle portion) 10 can be strengthened.

[0006] However, the cable tie M described in Patent Document 1 is composed of multiple components, namely a band portion 12 and a head portion (buckle portion) 10. Therefore, it is necessary to manufacture the band portion 12 and the head portion (buckle portion) 10 separately and then connect them, which results in a time-consuming and costly manufacturing process.

[0007] Furthermore, the cable tie M described in Patent Document 1 requires the head portion (buckle portion) 10 to be wrapped around multiple members, and then the tip of the band portion 12 to be inserted into the insertion hole 13 of the head portion (buckle portion) 10 to fasten it. As a result, fastening takes time and effort, and unfastening also takes time and effort.

[0008] This invention has been made in view of the above-mentioned problems of the conventional invention, and aims to provide a binding strip that is made from a single component, does not require time or cost to manufacture, can be used to bind multiple members simply by wrapping it around them, and does not require time or effort to bind or unbind. [Means for solving the problem]

[0009] To achieve the above objective, the binding strip of the present invention is a flexible, elongated strip, characterized in that surface interlocking pieces, which are in the shape of protrusions, are formed on the surface side of the elongated strip-shaped continuous strip at equal intervals in the longitudinal direction, and back interlocking pieces, which are in the shape of protrusions, are formed on the back side of the continuous strip at equal intervals in the longitudinal direction.

[0010] Herein, the surface interlocking piece is formed to protrude from the surface of the strip-shaped continuum at an inclination angle of 10° to 30°, and the back surface interlocking piece is formed to protrude from the back surface of the strip-shaped continuum at an inclination angle of 10° to 30°.

[0011] Furthermore, the strip-shaped continuous body, the surface interlocking piece, and the back interlocking piece are formed to the same thickness, and are characterized in that the back interlocking piece can be fitted into the gap between adjacent surface interlocking pieces, and the surface interlocking piece can be fitted into the gap between adjacent back interlocking pieces.

[0012] Furthermore, the surface interlocking piece may be formed as a flat plate-like portion of the same width from the base end to the middle portion connected to the strip-shaped continuum, and as a curved projection from the middle portion to the tip, while the back interlocking piece may be formed as a flat plate-like portion of the same width from the base end to the middle portion connected to the strip-shaped continuum, and as a curved fitting recess from the middle portion to the tip. [Effects of the Invention]

[0013] The binding strip of the present invention is made from a single component, so it does not require time or cost to manufacture, and since it can be used to bind multiple components simply by wrapping it around them, it does not require time or effort to bind or unbind.

Embodiments for Carrying out the Invention

[0015] Hereinafter, preferred embodiments of the binding strip of the present invention will be described in detail with reference to the drawings.

[0016] As shown in FIGS. 1 and 4, the binding strip 10 of one embodiment of the present invention is a long strip having elasticity and flexibility formed from a material such as synthetic resin or synthetic rubber. Here, as the material of the binding strip 10, synthetic resins such as polyamide resin (nylon), polypropylene, thermoplastic polyurethane resin (TPU), synthetic rubbers such as chloroprene rubber, silicone rubber, natural rubber, etc. can be adopted, but any material can be used as long as it has elasticity and flexibility.

[0017] As shown in FIGS. 1(A) and (B), the binding strip 10 is formed by protruding surface engagement pieces 12 having a protruding piece shape at equal intervals in the length direction on the front surface side of a strip-shaped continuous body 11 having a long strip shape, and protruding back surface engagement pieces 13 having a protruding piece shape at equal intervals in the length direction on the back surface side.

[0018] The surface engagement piece 12 is formed into a flat plate portion 12A having the same width from the base end portion 12a connected to the strip-shaped continuous body 11 to the intermediate portion 12b, and a curved protruding portion 12B from the intermediate portion 12b to the tip portion 12c.

[0019] The back surface engagement piece 13 is formed into a flat plate portion 13A having the same width from the base end portion 13a connected to the strip-shaped continuous body 11 to the intermediate portion 13b, and a curved recessed portion 13B from the intermediate portion 13b to the tip portion 13c.

[0020] Further, the surface engagement piece 12 protrudes at an inclination angle α with respect to the front surface of the strip-shaped continuous body 11, and the back surface engagement piece 13 protrudes at an inclination angle α with respect to the back surface of the strip-shaped continuous body 11. Here, the inclination angle α is preferably 10° to 30°, and particularly preferably 10° to 15°.

[0021] The strip-shaped continuous body 11, the surface interlocking piece 12, and the back interlocking piece 13 are formed to the same thickness, and are formed so that the back interlocking piece 13 can be fitted into the gap between adjacent surface interlocking pieces 12, 12, and the surface interlocking piece 12 can be fitted into the gap between adjacent back interlocking pieces 13, 13.

[0022] The binding strip 10 can be formed to a width and length suitable for wrapping around the members to be bound, but it is preferable that the width be wider than that of a general binding band, approximately 10 to 50 mm, so that even relatively large diameter members can be bound. When the binding strip 10 is formed into a long length, as shown in Figure 4, it is wound spirally and stored as a wound body 15. The wound body 15 is then pulled out sequentially from its tip, cut to the appropriate length, and used.

[0023] The binding strip 10 can be continuously manufactured in strips of appropriate length by extrusion molding or the like of a thermoplastic resin, but the manufacturing method is not particularly limited.

[0024] Furthermore, by using a 3D printer and performing fused deposition modeling of thermoplastic resin, strip-shaped bodies of appropriate lengths can be manufactured in a spiral shape. In this case, it is preferable to use a synthetic resin such as thermoplastic polyurethane resin (TPU) when carrying out fused deposition modeling.

[0025] Here, when manufacturing the binding strip 10 using a 3D printer, as shown in Figure 2, a surface interlocking piece 12' can be easily formed that is curvedly connected to the continuous strip 11 at the base end 12a and has a cross-sectional shape that curves outward from the base end 12a to the tip end 12c.

[0026] Similarly, when manufacturing the binding strip 10 using a 3D printer, as shown in Figure 3, a surface interlocking piece 13' can be easily formed that is curvedly connected to the continuous strip 11 at its base end 13a and has a cross-sectional shape that curves outward from the base end 13a to the tip end 13c.

[0027] Next, the method of use and operation of the binding strip 10 of the present invention will be described in detail with reference to the drawings.

[0028] When tying and connecting two pieces of wood 50, 50, as shown in Figure 4, the binding strip 10, which is a wound body 15, is pulled out, cut to an appropriate length, and then wrapped around the two pieces of wood 50, 50 so that the binding strip 10 is layered on top of each other.

[0029] Here, when stacking and wrapping the binding strip 10, as shown in Figure 6(A), the surface of the back surface interlocking piece 13 can slide in the wrapping direction against the surface surface interlocking piece 12 of the binding strip 10 located in the lower layer, so that the binding strip 10 can be easily wrapped in an appropriate shape and with appropriate strength.

[0030] Then, after stacking and wrapping the binding strip 10, as shown in Figure 6(B), the binding strip 10 is slightly unwound due to its elasticity, and the tip of the surface interlocking piece 12 of the binding strip 10 fits into the gap between the back interlocking pieces 13. As a result, the binding strip 10 is not unwound any further, and the binding strip 10 can be easily fastened.

[0031] On the other hand, when releasing the binding of two pieces of wood 50,50 and separating them, if the tip of the fastened binding strip 10 is pulled slightly and moved in the width direction, the tip of the surface interlocking piece 12 of the binding strip 10 will escape from the gap between the back interlocking pieces 13, so the fastening by the binding strip 10 can be easily released.

[0032] As described above, the binding strip 10 of the present invention does not have a head portion (buckle portion) as a component, unlike conventional binding bands, and is composed only of a single strip-shaped component, thus saving both time and cost in manufacturing.

[0033] Furthermore, with the binding strip 10 of the present invention, binding can be done simply by stacking and wrapping it around multiple members to be bound, and the binding can be released by moving it in the width direction while slightly pulling it, thus saving time and effort in binding and releasing.

[0034] In the case of the binding strip 10, the surface interlocking piece 12 is formed from a flat plate-shaped portion 12A and a curved projection 12B, and the back surface interlocking piece 13 is formed from a flat plate-shaped portion 13A and a curved fitting recess 13B. Therefore, when wrapping, the curved projection 12B is smoothly introduced from the curved fitting recess 13B to the flat plate-shaped portion 13A, making it easier to fasten the binding strip 10.

[0035] Furthermore, the form of the binding strip of the present invention is not limited to the binding strip 10 shown in Figure 1, but a form such as the binding strip 30 shown in Figure 7 may also be adopted.

[0036] The binding strip 30, like the binding strip 10, is a long, continuous strip 31 with surface interlocking pieces 32 forming protrusions at equal intervals along its length on the surface side and back interlocking pieces 33 forming protrusions at equal intervals along its length on the back side.

[0037] As shown in Figures 7(A) and (B), the binding strip 30 has the same shape for the surface interlocking piece 32 and the back interlocking piece 33, and is formed as flat plate-like portions 32A and 33A of the same width from the base end portions 32a and 33a that connect to the continuous strip 31 to the tip portions 32c and 33c.

[0038] With this binding strip 30, since the shape of the surface interlocking piece 32 and the back interlocking piece 33 is simple and flat, it takes less time and money to manufacture compared to the binding strip 10. However, during winding, the end of the surface interlocking piece 32 may catch on the end of the back interlocking piece 33, making it slightly difficult for the surface interlocking piece 32 to fit into the back interlocking piece 33.

[0039] Furthermore, the form of the binding strip of the present invention is not limited to the forms of binding strip 10 and binding strip 30, and the interlocking pieces on the front and back surfaces may be the same shape or different shapes, as long as they perform the above functions.
