Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a sheet holder used for fixing sheets in a greenhouse. The present invention relates to a seat receiver that can be easily fixed by fitting with the seat receiver.

``Prior Art'' Conventional seat holders of this type include a long dovetail groove on the bottom surface of the seat holder, as disclosed in Design Registration No. 688626 and Design Registration No. 688627, for example. A pipe fitting groove has been proposed in which the gap between both edges of the opening is narrowed in the longitudinal direction and the cross section is approximately arcuate. A corrugated elastic wire is inserted into the sheet, and the sheet is clamped and held by the elastic wire and the side wall surface of the dovetail-shaped interior. Further, these seat holders are integrally extruded from synthetic resin or aluminum alloy.

``Problems to be solved by the invention'' The conventional sheet receiver described above can be fixed by simply fitting the frame pipe of the greenhouse into the pipe fitting groove, so the work of fixing it to the frame pipe is extremely simple. However, if it is fixed to a frame pipe that is curved in an arch shape, such as a frame pipe on a roof, the pipe fitting groove will become weak due to strain, and the pipe will be bent along the frame pipe. Since the fixed seat holder attempts to return to its straight state, there is a risk that the seat holder may come off from the frame pipe due to strong winds or temperature changes.

Furthermore, depending on the curvature of the arch-shaped frame pipe, there is a drawback that it becomes difficult to fit the pipe into the pipe fitting groove.

The purpose of this invention is to allow the pipe to be easily fixed to arch-shaped frame pipes, and to prevent it from coming off the frame pipe due to wind or temperature changes. The object of the present invention is to provide a seat receiver that can use a locking pin.

"Means for Solving the Problems" In order to achieve the above-mentioned object, the present invention includes a long dovetail-shaped seat receiving part, and a seat receiving part that is integrally formed along the longitudinal direction on the lower surface of the seat receiving part. It consists of a pipe fitting groove with an opening facing downward or sideways and a substantially arcuate cross section with a narrowed gap between both edges of the opening. Cutouts of an appropriate width are formed at predetermined intervals on both side walls so that the grooves are intermittent, and cutouts in the longitudinal direction from the maximum inner width W of the pipe fitting groove to both edges of the opening are formed on both side walls. A pin insertion hole is formed along the edge portion or the notch portion into which a locking pin can be inserted.

"Operation" The seat receiver according to the present invention is fixed to the frame pipe by pressing and fitting the pipe fitting groove into the frame pipe with the seat receiver facing outward. Since it is formed in a state where it is interrupted by notches, even when it is fixed to an arch-shaped frame pipe, it can be smoothly bent along the frame pipe.

In addition, if necessary, a locking pin in the form of a skim can be inserted from the end into the pin insertion hole on both side walls of the pipe fitting groove to prevent the pipe fitting groove from coming off from the frame pipe.

"Embodiments" Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 to 6 show the first embodiment, in which 1 is a long dovetail-shaped seat receiving portion in which both side walls 11 and 11 are opposite each other and curved in a hook-like cross section, and 2 is a seat receiving portion. 1

In this embodiment, the pin insertion holes 23 are formed in the edges 22 of the side walls 21 by bulging out to have a circular cross section.

In this embodiment, the pipe fitting groove 2 is formed in an intermittent state by forming narrow notches 3 at predetermined intervals on both side walls 21 of the pipe fitting groove 2. Interval L forming notch 3
The width l of the notches 3 is set as appropriate depending on the degree of bending of the frame pipe, but in normal dimension specifications, the interval L between the notches 3 is about 5 to 15 cm, and the width l of the notches 3
It is sufficient to set the width l to about 2 to 5 mm.
In general, if the interval L between the notches 3 is large, the width l of the notches 3 is large, and if the interval L is small, the width l may be set small.

FIGS. 4 to 6 show the seat receiver a of the above embodiment.
is fixed to a frame pipe 5 on the roof of a greenhouse, and a sheet b is fixed to a sheet receiving portion 1 of a sheet receiving device a.

The frame pipes 5 are arranged in parallel at predetermined intervals in the direction of the ridge of the greenhouse, and the roof part is bent into an arch shape.
The frame pipes 5 are connected to each other by ridge members 6 or purlins (not shown). The seat receiving tool a is made by pressing the pipe fitting groove 2 against the frame pipe 5 from above with the seat receiving part 1 facing upward, and then pressing the fitting groove 2 against the frame pipe 5.
to fit. Since the pipe fitting groove 2 is interrupted by the notches 3, it can be easily fitted along the curved frame pipe 5.

The seat receivers a may be attached to each of the frame pipes 5 that are arranged in parallel, or
In some cases, they are attached every few pieces to a large number of frame pipes 5 arranged in parallel.

When inserting the locking pin 4 into the pin insertion holes 23, 23 of the pipe fitting groove 2, insert it from the end of the fitting groove 2 or from the notch 3. In places where the wind is not strong, it is sufficient to use the lock pins 4 at both ends of one seat holder a (about 2 m in length), but in windy places, it is sufficient to use the lock pins 4 at the middle part of one seat holder a. It is also preferable to use an appropriate number of lock pins 4.

When inserting the lock pin 4 into the pin insertion holes 23, 23 in the middle part of the seat receiver a,
As shown in FIG. 9, while fitting the frame pipe into the pipe fitting groove 2 from one end, insert the lock pin 4 into the pin insertion holes 23, 23 from the notch 3. In this case, it is preferable to use a locking pin 4 with a head 41 bent downward as shown in FIG. 10.

As shown in FIGS. 5 and 6, the sheet b is inserted into the dovetail-shaped interior of the sheet receiving part 1 by means of a corrugated elastic wire 7, and is compressed by the elastic wire 7 and the inner wall of the sheet receiving part 1. It will be fixed in this state. Elastic wire rod 7
