Description

[Detailed explanation of the idea] At the ends of the greenhouse, if the pipes connected vertically and horizontally are not firmly tightened, the house will become unstable, and the ends of the pipes will touch the sheet, causing the sheet to become unstable. Breaking occurs frequently.

Therefore, conventionally, as an end enclosing device for the aggregate of a vinyl greenhouse, a hook was provided on one side of a tube with rounded corners at the tip, and screw seats were hung on both sides below the base to connect the end of the pipe. Ingredients (Jitsukikai No. 53-156311),
and a pipe end fastener consisting of a short pipe with one end closed and a linear band member (Utility Model Application No. 107750/1983)
has already been filed.

However, these are composed of a linear band member and a short tube that fits into the end of the pipe, so they lack integrity and have the disadvantage that the connections between the vertical and horizontal pipes can become misaligned due to vibration or long-term use.

In addition, in the case of Utility Model Application No. 107750/1983, there is a risk that the sheet may be damaged by the corners of the closed end of the short tube.

In view of the above, the present invention relates to a connecting tool that firmly tightens pipes connected vertically and horizontally and prevents sheets from tearing at the ends of the pipes. An upper pipe holding part 2 is formed in the upper bent part 1, and a short cylindrical part 6 into which the end of the lower pipe 5 perpendicular to the upper pipe 4 is fitted into the hanging wall 3 connected to the bent part 1. is formed, which closes one end of the short cylindrical part, and makes the corner of the end a curved surface, while connecting to the upper pipe holding part 2 and facing the short cylindrical part. An orthogonal lower pipe holding part 7 is formed, and a diagonally convex rib 8 extending from the tip to the top of the upper pipe holding part 2 is integrally molded on the top of the lower pipe holding part 7.

Reference numeral B designates a belt-shaped fastener, which is fixed to the lower pipe holding portion 7 with bolts 9 and nuts 10, and is used to tighten the lower pipe 5 from below.
Note that 11 in the figure is a sheet.

The present invention has the above-mentioned structure, and to explain its function and effect with reference to the drawings, Fig. 6 shows the state in which it is used. When the end of the lower pipe 5 perpendicular to the upper pipe 4 is inserted into the short cylindrical part 6 of the device of the present invention and the bolt 9 and nut 10 are tightened, the fastener B tightens the lower pipe 5 from below. It raises it.

This tightening action is achieved because the short cylindrical portion 6, the bent portion 1, and the convex rib 8 are integrally formed, so when the bolt 9 is tightened, the rib 8 and the lower pipe holding portion 7 are pulled downward. The upper pipe 4 strongly presses the lower pipe 5, and the end of the lower pipe 5 is connected to the short cylindrical part 6.
Since the pipes 4 and 5 are fitted into the upper pipe holding part 2, the upper pipe 4 and the lower pipe 5 are tightly tightened by the action of the screw.
Since it is immovably held by the lower pipe holding part 7, it will not come loose due to vibration.

In addition, in the device of the present invention, the end of the lower pipe 5 is a short cylindrical part 6.
Since it is fitted inside, the sheet 11 does not touch the sheet 11, and since the corner of the closed end of the short tube section 6 is formed into a curved surface, there is no risk of the sheet 11 being torn even if the sheet 11 is touched. It is.

In addition, the device of the present invention can freely attach and detach pipes by simply operating the bolts 9, and is extremely easy to handle, making it a useful device with many effects.
