Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the improvement of corrugated wire rods used to fix vinyl sheets to vinyl sheet support frames in greenhouses, etc. This invention relates to a corrugated wire used for fixing a vinyl sheet with a knob that can be easily attached to and detached from a vinyl sheet.

[Conventional technology]

Various types of vinyl sheet tensioning equipment have been proposed and put to use in the past, and among them, support frames with a dovetail-shaped cross section are said to be particularly excellent. In this method, a vinyl sheet is inserted into the dovetail groove of the support frame using a corrugated wire rod whose trapezoidal parts are alternately continuous on the left and right sides, and the elastic force of the corrugated wire rod is used to clamp and fix the sheet to both the left and right sides of the dovetail groove. be.

Since the corrugated wire is cut into a certain length (usually 2 m), the cut ends are often burred and sharp. Therefore, when the vinyl sheet 4 is fixed in the dovetail groove 2 of the long strip material 1 with the corrugated wire rod 3 as shown in FIG. The vinyl sheet 4 may be torn, and once it is torn, the vinyl sheet 4 will be exposed to wind and rain and begin to tear from this part, so it will be necessary to partially replace the vinyl sheet 4.

In addition, since the corrugated wire rod 3 is cut to a certain length, it can be used, for example, when fixing the raw material of the vinyl sheet 4 in the dovetail groove 2 of the support frame 1 long arranged along the rafters or main building of a vinyl house. teeth,
The vinyl sheet must be fixed by sequentially applying the corrugated wire 3.

In this case, if the end 5 of the corrugated wire 3 is wrapped, the chance of the vinyl sheet getting caught can be halved and damage can be reduced, so the end 5 of the corrugated wire 3 is always wrapped. During the work, the vinyl sheet 4 must be quickly stretched and fixed, and it is difficult to check the length of the wrapped end, so the wrap length of the end of the corrugated wire may be one peak or two peaks of the waveform. It is not constant, sometimes it is half of a mountain, sometimes it is half of a mountain.

In addition, as shown in Figures 6 and 7,
The proposal disclosed in Publication No. 27639 and Japanese Utility Model Application Publication No. 58-60009 is to apply a coating 6 to both ends of the corrugated wire to prevent the vinyl sheet from being attracted to the end surface of the corrugated wire or to be torn, and to color the coating. This makes it easy to identify when the corrugated wire continues.

[Problem that the invention attempts to solve]

However, the conventional corrugated wire 3 has both ends 5, 5
Since the vinyl sheet is simply cut, the vinyl sheet may be damaged by the ends 5, 5 when it is pressed down to fix the original vinyl sheet in the dovetail groove 2 of the long strip 1. Further, after the sheet is fixed, it is agitated by the wind, and the vinyl sheet is torn from both ends 5, 5 of the corrugated wire 3.

The corrugated wire rod 3 is a steel wire with a length of about 2 m, and its elasticity is used to create a dovetail groove in the support frame 1.
However, there was a problem in that the face and eyes were injured during the process.

Next, the above-mentioned Utility Model Publication No. 58-27639 and Utility Model Application Publication No. 58
The corrugated wire 3 proposed in Publication No. 60009 is also simply coated with a coating 6 on both ends, which is useful for making it easy to identify both ends and making it easy to keep the length of the wrapped ends constant. Even so, the corrugated wire 3
It is not possible to completely prevent damage to the vinyl sheet at both ends of the sheet, and in particular, when removing the corrugated wire 3 attached to the long strip 1 from the dovetail groove 2, it is necessary to pry it off using a screwdriver or the like. As with the conventional example, there is a problem in that it requires a lot of effort and special technology.

Furthermore, the above proposed corrugated wire 3 rusts when exposed to wind and rain during use, and when the vinyl sheet is agitated by the wind, the rust occurs at the portion of the vinyl sheet that is in contact with the corrugated wire 3. It had the disadvantage that it was damaged and could be torn from there.

The present invention was devised in view of the above circumstances, and consists of a trapezoidal part of a corrugated wire except for both ends thereof, which is covered with vinyl or the like, and a knob provided with square gripping parts at both ends. To provide a corrugated wire rod for fixing a vinyl sheet that has a simple structure, does not damage the vinyl sheet at all during installation and use, and is extremely easy to install and remove by attaching the wafer to both ends of the corrugated wire rod. It is an object.

[Means for solving problems]

In order to achieve the above object, the present invention has a corrugated wire material for fixing a vinyl sheet of a certain length in which trapezoidal portions continue alternately on the left and right sides, and only the trapezoidal portion is made of vinyl or the like, excluding both ends of the corrugated wire rod. The trapezoidal part is cut in half, and the trapezoidal part is cut in half, and the trapezoidal part is cut in half, and the trapezoidal part is cut in half to form a square gripping part with one side having the same length as the end. Insert the tubular part of the synthetic resin knob that protrudes from the side part into the side part, and insert it past the bending point of the corrugated wire until the corner of the square grip part touches the bending point, It is characterized by being worn.

[Effect]

Next, the operation of the present invention will be explained.

Insert the tubular part of the synthetic resin knob into both ends of the corrugated wire, and insert it past the bending point of the corrugated wire until the corner of the square grip touches the bending point. It is inserted to the middle of the hypotenuse between the top and the top. When fixing a vinyl sheet to a support frame using a corrugated wire rod of a certain length in which the trapezoidal parts to which synthetic resin knobs are attached alternately on the left and right sides, the vinyl sheet is first attached to one end of the corrugated wire rod. Pinch the square gripping part of the knob with your fingertips and push it into the dovetail groove along with the vinyl sheet, then push the trapezoidal part one by one into the dovetail groove of the support frame, and use the elastic force of the corrugated wire to clamp and fix it on both the left and right sides of the dovetail groove. I will do it. When the end of the corrugated wire is reached, the square grip part of the knob attached to the end is pinched with the fingertips and pushed into the dovetail groove, thereby completing the attachment of one corrugated wire.

Furthermore, when installing corrugated wires in succession, push the knob attached to the tip of the next corrugated wire onto the opposite side of the dovetail groove that opposes the end of the corrugated wire, and repeat the same process. Repeat.

In this way, when fixing a vinyl sheet, the resistance increases towards the end of a single corrugated wire due to the elastic force of the wire, making it difficult and dangerous to press the end.However, the corrugated wire of the present invention As shown in the figure, the handles are equipped with square grips at both ends, making it easy to push in the end, completely preventing damage to the vinyl sheet, and preventing rust from forming on the corrugated wire during use. This completely prevents damage to the vinyl sheet.

Furthermore, when replacing the fixed vinyl sheet, the corrugated wire can be easily and quickly removed by pulling out the square grip portions of the knobs attached to both ends of the corrugated wire.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

Figure 1 shows the waveform of a corrugated wire 9 of a certain length (usually 2 m), in which trapezoidal parts 7 are alternately continuous left and right and both ends are cut midway between the top sides of the trapezoidal parts 7, with both ends 8, 8 removed. The wire 9 is entirely covered with a coating P made of vinyl or the like, and in one embodiment of the present invention shown in FIG. and
Furthermore, the tubular portion 11 of a synthetic resin knob 12 consisting of a square grip portion 10 and a tubular portion 11 shown in FIG. 3 is inserted into both ends 8, 8 which are not covered.

This knob 12 is integrally molded from vinyl, nylon, etc., and the tubular parts 11 are continuously molded on both sides of the square grip part 10, and then cut on site as shown in FIG. 3 to form the single knob 12. It is used as a.

Next, the state of use of this embodiment will be explained.

At the work site of a plastic greenhouse, the end part 8 of the corrugated wire rod 9 is inserted and fixed from the protruding side of the tubular part 11 of the knob 12 attached to both ends of the corrugated wire rod 9 having a constant length of about 2 m.

At this time, since the knob 12 is made of synthetic resin and the tubular part 11 is flexible, it is inserted past the bending point of the corrugated wire 9 until the rectangular grip part 10 touches the bending point, and as a result, the tip of the tubular part Since it is inserted up to the middle of the inclined side 13 on the way to the top side, the knob 12 is securely fixed by its own elasticity.

At that time, hold the knob 12 so that the end 8 of the corrugated wire 9 does not protrude from the end surface of the tubular part 11 of the knob 12.
The size of is determined.

When fixing the corrugated wire rod 9 to which such a knob 12 is attached to the dovetail groove 2 of the support frame 1 via the vinyl sheet 4, first, the square grip part 10 of the knob 12 attached to one end of the corrugated wire rod 9 is fixed. Pinch it with your fingertips and push it into the dovetail groove 2 together with the vinyl sheet 4, then push the trapezoidal part 7 into the dovetail groove 2 of the support frame 1 one after another, and clamp and fix it on both left and right sides of the dovetail groove 2 by the elastic force of the corrugated wire 9. To go. When the end of the corrugated wire 9 is reached, the square grip part 10 of the knob 12 attached to the end is pinched with the fingertips and pushed into the dovetail groove 2 in the same manner, completing the attachment of one corrugated wire 9.

Furthermore, when the corrugated wire rods 9 are installed in succession, a knob 1 is attached to the tip of the next corrugated wire rod 9 on the opposite side of the dovetail groove 2 that opposes the terminal end of the corrugated wire rod 9.
2 into position, and repeat the same process.

In this way, when fixing the vinyl sheet 4, the closer you go to the end of one corrugated wire 9, the more resistance increases due to the elastic force of the wire 9, making it difficult and dangerous to push the end. A knob 12 with square gripping parts 10 at both ends like the corrugated wire 9 in the example
Since it is attached, it is easy to push in the end part, and damage to the vinyl sheet can be completely prevented.

In this way, the vinyl sheet 4 is fixed to the dovetail groove 2 of the support frame 1 by the corrugated wire rods 9, so even if the vinyl greenhouse is exposed to wind and rain during use, the portions of the corrugated wire rods 9 that are in contact with the vinyl sheet will remain intact. Since rust does not occur, the vinyl sheet 4 is not damaged.

Furthermore, when replacing the fixed vinyl sheet, the corrugated wire can be easily and quickly removed by pulling out the square grip portions 10 of the knobs 12 attached to both ends of the corrugated wire. .

[Effect of idea]

According to the present invention having the above configuration, the trapezoidal part of the corrugated wire except for both ends is covered with vinyl or the like, and the tubular part of the synthetic resin knob with the square grip part is connected to the both ends of the corrugated wire. When attached to the
The tubular part can be easily inserted past the bending point of the corrugated wire until the rectangular grip part contacts the bending point, and as a result, the tip of the tubular part is inserted halfway between the inclined sides on the way to the top edge, so the tubular part The handle is bent, so it can be securely fixed to the corrugated wire by the elasticity of the knob itself.Furthermore, it is easy to hold the square grip when tightening the vinyl sheet, and it is easy to use during use. The tubular part allows the vinyl sheet to be securely fastened to the corner of the dovetail groove of the support frame, and since the square grip part does not protrude from the end surface of the corrugated wire, it will not get caught on the vinyl sheet and cause damage. In addition, there is no rust on the trapezoidal part that fastens the corrugated wire vinyl sheet during use, and damage to the vinyl sheet can be completely prevented. It can be easily removed by pinching the holding part and pulling it out.

In addition, since the knob of the present invention is made of synthetic resin, it is flexible and easy to handle, and can be easily attached on site.The grip part is square, making it easy to grasp, making it easy to attach and detach the end of the corrugated wire. It is very convenient.
