Description

[Detailed Description of the Invention] The present invention relates to a wrapping sheet that is mainly used for wrapping around utility poles to display danger signs, prevent pasting, etc.

Conventionally, such sheet-like materials have metal bands, wires, etc. attached to both edges and are fixed with bolts, nuts, etc. on the back side of utility poles, etc., but it is difficult to attach metal bands, wires, etc. Tightening is cumbersome and has poor workability, and it also has the disadvantage that bolts cannot be tightened unless the length of the metal band or wire is adjusted in advance each time the diameter of the utility pole differs.

In view of these shortcomings, the inventor has conducted extensive research and found that
By forming irregularities on the seat body itself and overlapping and fittingly locking both edges of the seat body, they succeeded in solving this problem and completed the present invention.

The present invention will be described in detail below with reference to the drawings.

In the drawings, 1 is the seat body. The sheet body 1 is made of synthetic resin such as polyethylene or polyvinyl chloride, or metal such as stainless steel or aluminum. Further, the color of the sheet body 1 may be determined as appropriate depending on the purpose of use.
For example, if the purpose is to prevent danger, it may be yellow, or yellow and black stripes, etc. If the purpose is to prevent pasting, it may be in an inconspicuous color such as gray or dark green. You may also use a pattern etc.

2 is a concave groove, and 3 is a convex strip, both of which are formed on the inner and outer walls of the sheet body 1. In other words, the concave groove 2 portion on the front side of the sheet body 1 is a convex line 3 when viewed from the back side, and the convex line 3 on the front side is a concave groove 2 when viewed from the back side.
It is. The shapes of the grooves 2 and the protrusions 3 are as follows.
The side walls may be vertical as shown in FIGS. 3 and 2, or may be inclined as shown in FIGS. 3 may have different shapes. Also, groove 2
It is preferable that the protrusions 3 and 3 are shaped so that they fit into each other when they are overlapped as shown in Fig. 3.
They may be shaped so that they fit into each other by being slightly deformed when they are overlapped and pressed as shown in FIGS. 4 and 5. Furthermore, if the grooves 2 and the protrusions 3 are formed on the entire surface of the sheet body 1, and if a plurality of grooves are formed at least on both edges, the grooves 2 and the protrusions 3 can be adjusted within the overlap range. In addition, it is preferable because it improves functions such as being able to draw letters and signs on smooth areas without grooves 2 and ridges 3, and to attach reflective tape.
Furthermore, by widening the width at one end along the longitudinal direction of the grooves 2 and the protrusions 3 and narrowing the width at the other end, it becomes easier to align the seat body 1 along a conical outer wall like a telephone pole. Preferably, in this case, it is even more preferable that the outer shape of the sheet body 1 itself is also slightly fan-shaped.

Next, a method of using the wrapping sheet of the present invention will be described.

First, the sheet body 1 is curved along the outer wall of a columnar body 4 such as a utility pole so that both edges overlap. Next, press the edge on the outer side to fit and lock the grooves 2 and ridges 3 on the inner wall of the edge into the grooves 3 and grooves 2 on the outer wall of the inner edge, respectively. Bye.

As detailed above, the wrapping sheet of the present invention has concave grooves and protrusions alternately formed on both the front and back sides of the sheet body, and the protrusions on the front side form concave grooves when viewed from the back side. The grooves and grooves on the inner wall of the edge are fitted into the grooves and grooves on the outer edge of the other sheet body, so that the seat body can be attached to the outer wall of a columnar object such as a utility pole. Both edges can be bent by simply placing the two edges together and pressing the grooves and grooves on the inner wall of the outer edge into the grooves and grooves on the outer wall of the inner edge. Fitting and locking eliminates the need for metal bands, wires, bolts, nuts, etc. for fixing both edges, making it easy to attach to the columnar body, and even if the diameters of the columnar bodies are different, both edges can be fixed. It can be attached simply by fitting the grooves and protrusions on the part. Further, when the grooves and the protrusions are formed on the entire surface of the sheet body, the wrapping sheet can be wrapped twice (triplely at both edges) around the outer wall of the columnar body.
