BACKGROUND OF THE INVENTION
In order to suppress the sheet material covering the greenhouse and the sheet material covering the truck bed with a band that is tensioned from the top, the present invention holds one end of the band at a locking member such as a frame of a greenhouse or a hanging tool of a truck. It is related with the band fastener for latching to.
[0002]
[Prior art]
Conventionally, band fasteners have been used to fix one end of the band that holds the sheet material covering the loading platform of a greenhouse or truck to a locking member such as a greenhouse frame, a truck hook, or a rope. .
[0003]
Conventionally, a greenhouse is formed by forming a frame with pipes and sticks, covering it with a vinyl sheet, holding the vinyl sheet on the mica wire on top of it, and fixing it to the pipe.
[0004]
FIG. 5 is a perspective view showing a greenhouse to which a band fastener is applied. A plurality of arched pipes P are erected in parallel on the ground, and these two sides are connected by straight pipes fixed on the ground. After forming the frame, the vinyl sheet is placed on the pipe, the band B is hung on the vinyl sheet S, the band B is pulled and fixed to the pipe P, and the vinyl sheet S is pressed.
[0005]
6A and 6B are perspective views of a conventional band fastener, wherein FIG. 6A is a perspective view and FIG. 6B is a cross-sectional view.
[0006]
The band fastener 1 is arranged in such a manner that a pair of rectangular frames 20a and 20b, a connecting band 21 connecting both the rectangular frames 20a and 20b, and the rectangular frame 20b can be crossed left and right when used. The support rod 22 is provided.
[0007]
For example, the other end of the band B is fixed to the plastic house pipe P by an appropriate means, and then the one end side is hooked to the band fastener 1 attached to the pipe B. In this case, the band fastener 1 is attached to the pipe P by engaging the connection band 21 between the two frame bodies 20a and 20b by winding and folding the connection band 21 around the pipe P. Next, one end of the band B is inserted into the frame from one side of the rectangular frame 20a, 20b to the other side, and at the other end, one end of the band B is detoured by the support rod 22, and again the gap When one end of the band B is pulled strongly, the length of the band B is adjusted in proportion to the pulling amount and is held in a tensioned state.
[0008]
[Problems to be solved by the invention]
The band fasteners can be securely fixed by holding the band B against the pipe P while being stretched while adjusting the length of the band, and can be temporarily disassembled when used frequently or when a typhoon approaches, Since assembly is performed, it is preferable that attachment and removal are easy.
[0009]
However, in the conventional band fastener, when the band B is elastically extended to some extent by long-term use, for example, one end of the band B is pulled back to tension, and the tensioned state is not maintained. In this case, the band must be tensioned again by pulling one end of the band B.
[0010]
Further, in the attaching operation, the connecting frame 21 is wound around the pipe P, the two frame bodies 20a and 20b are brought into contact with each other while being deformed into a U shape, and the support rods 22 are disposed on the rectangular frame bodies 20a and 20b. In addition, since one end of the band B must be assembled with both the frame bodies 20a and 20b and the support rod 22 being held by hand, the operability is poor and the usability is poor.
[0011]
Furthermore, when removing the used band fastener 1 by dismantling the greenhouse, for example, pulling the band B toward the fastener 1 and forming a bend between one end of the band B, with one end being a gap Since it has to be returned to the side, it takes a lot of time to remove a large number of fasteners, which is a troublesome work.
[0012]
The present invention provides a band fastener excellent in operability that can securely lock a tensioned band and can be quickly removed.
