Description

[Detailed description of the invention] [Industrial application field] This invention is useful for attaching filaments such as strings to prevent sagging, wrinkles, and unevenness of sheets in greenhouses such as greenhouses. This invention relates to a device for attaching sheet presser strings, etc. in a greenhouse to be used.

[Conventional technology]

In general, greenhouses, which are vinyl greenhouses made of vinyl sheets, are made with a sheet facing the sheet in order to regulate or restrain the tension of the sheet and stabilize it against external forces, as well as to prevent the sheet from sagging or wrinkling. Seat restraint strings, bands, wires, etc. are used to hold the seat in place.

As disclosed in Japanese Utility Model Publication No. 52-53899, both ends of this string are connected to stoppers provided on both sides of the house, and the sheet is held down with an arbitrary tension. This stopper is attached to the dovetail groove and edge of the support frame having a narrow opening for fixing the sheet by utilizing its own elasticity.

On the other hand, conventional sheet fixing consists of a support frame with a narrow opening installed between pipes that stand up in an arch shape, and elastic locking lines that fit the synthetic resin sheet into this support frame. Ori,
If the sheet to be fixed is soft, it has elasticity, so when it is held in the support frame by the locking lines, sufficient tension can be obtained and it can be spread uniformly over the entire house.

However, when this soft sheet is stretched, there is a problem that the sheet itself has poor durability and deteriorates during long-term use, causing cracks or breakage.

Furthermore, greenhouses need to allow sufficient sunlight to pass through, but in the case of the above-mentioned soft sheets, they change color during use, lowering the transmittance of sunlight, and dirt easily adheres to the outside surface due to the characteristics of the material. Due to problems, the seats have to be replaced every year. For this reason, reupholstering the sheet is troublesome,
It was also economically disadvantageous.

On the other hand, hard synthetic resin sheets such as polyester resin sheets are also known, which are durable, resistant to discoloration, and have good sunlight transmittance.Using this hard sheet can eliminate the above problems. It is known that the problem can be solved, and its use has been desired for many years.

However, this hard sheet has poor elasticity, high rigidity, and is relatively thick, so it cannot be fixed using conventional sheet fixing devices, and if you try to force it to fix it, wrinkles or cracks may occur. Put it away.
Moreover, if you use it while these wrinkles and cracks remain,
The entire sheet may flap or be turned over and broken due to strong winds, etc. Therefore, it has not been possible to actually stretch a rigid sheet.

However, recently, the present applicant has developed a sheet fixing device that is good for fixing hard sheets that does not cause wrinkles and prevents cracks (Utility Application No. 62-48417).
issue).

[Problem that the invention attempts to solve]

The conventional seat restraint straps and other fasteners shown in the above publication expand within the dovetail grooves of the support frame due to their own elasticity, and are hooked on the dovetail grooves and edges of the support frame, so they cannot be easily restrained by wind pressure, etc. When an external force is applied to the sheet and the string, the stopper itself moves, and the sheet is rubbed between the stopper and the edge of the support frame, causing the sheet to break.

Furthermore, as mentioned above, the newly developed fixing device for hard sheets consists of a support frame with a narrow opening and a sheet holding member that fits the sheet into the support frame. A new problem also occurred in that it was difficult to attach the conventional stopper to the dovetail groove and the edge of the support frame because there was not much clearance near the edge of the support frame when the support frame was moved.

Therefore, the purpose of the present invention is to allow the sheet to be attached even if there is no large gap near the edges of the support frame, unlike the newly developed sheet fixing device mentioned above, and to prevent the sheet from moving even under external force after fixing. It is an object of the present invention to provide a device for attaching sheet presser strings, etc. in a greenhouse that does not require abrasion.

[Means for solving problems]

In order to achieve the above purpose, the configuration of the present invention is as follows:
It consists of a support frame with a narrow opening width, a sheet holding member for fitting the sheet into the support frame, and a bracket for attaching a sheet holding string, etc., and the sheet holding member consists of a plate portion, a sheet holding portion provided on the plate portion, and a sheet holding member. The sheet holding part consists of a leg bent double downward and a sheet holding piece extending laterally, and the bracket is a plate fixed in the support frame via the plate part of the sheet holding member. The device is characterized in that it is composed of a main body consisting of a body, and a connecting portion consisting of a hole provided in the body.

[Effect]

When the sheet presser member is fitted into the support frame, the bracket is also fixed within the support frame via the sheet presser member, and the sheet presser member is strongly fixed within the support frame while holding the sheet between them. The bracket does not move and the seat is not rubbed.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

The device of the present invention has a support frame 1 with a narrow opening.
, a sheet pressing member 2, and a bracket 3.

The support frame 1 includes a bottom portion and a pair of both side frames 4 and 5 that stand up in an inclined direction on both sides thereof, curls 6 and 7 provided at the top of the both side frames 4 and 5, and a pair of curls 6 and 7 provided between the bottom portion and the both side frames 4 and 5. The opening between the curls 6 and 7 is narrower than the width of the bottom.

The sheet presser member 2 consists of a plate portion 10, a curved thick wall portion 11 provided on the left side of the plate portion 10, and a sheet presser portion 12 provided on the right side.
It consists of a leg portion 13 that is double bent downward and a sheet holding piece 14 that extends laterally and is slightly curved. The thick portion 11 is intended to avoid adversely affecting the sheet, and may be omitted.

The bracket 3, which has a slightly curved surface 15 formed on the side surface of the leg portion 13, is a strap for restraining the seat.
This is a member to which a filament such as a wire is attached, and is composed of a main body 30, a hook portion 32 provided on the main body 30, and a hole 31 serving as a connecting portion. The body is metal,
Although it is molded from a plate made of synthetic resin or the like, it is not limited to a plate and may be a wire.

The coupling portion may be a hole, a hook, or a notch as shown. In short, it is sufficient that the filaments can be combined. Moreover, it is preferable to use a material and a shape that allows the angle to be adjusted arbitrarily when the filaments are combined.

The hook portion 32 is formed by bending the main body, but as shown in the figure, it is slightly bent to prevent the vicinity of its tip from interfering with the sheet. However, the hook portion 32 may be bent parallel to the main body 30 or slightly inclined.

When fitting the sheet 16 into the support frame 1 and fixing the bracket 3 at the same time, the following procedure is performed.

Place the sheet 16 on the support frame 1, hook or insert the hook part 32 of the bracket 3 onto the end of the plate part 10 of the sheet presser member 2, and in this state, hold the sheet through the thick part 11 of the sheet presser member 2. 16 and the hook portion 32 of the bracket 3 are inserted into the dovetail groove 8 on the left side of the support frame 1. At this time, the sheet holding member is inclined, and the thick portion 11 can hold the sheet 16 and the bracket 3 in the dovetail groove 8.

Next, the sheet holding portion 12 which is the other end of the plate portion 10 is
When the sheet is pushed into the support frame 1 from above, the leg portions 13 push the sheet 16 against the elasticity of the plate portion 10 and the elasticity of the leg portions 13, and fit into the dovetail groove 9 on the right side.

At this time, the plate part 10 is subjected to a restoring force that tends to spread laterally due to its own springiness, and this restoring force pushes the thick part 11 and the leg part 13 laterally, and the bracket is The sheet 16 is fixed in the dovetail groove 8 on the left side, and the sheet 16 is attached to the frame 4 on both sides.
5 and into the dovetail grooves 8 and 9, and is held in cooperation with the support frame 1. Moreover, since the thick portion 11 and the leg portion 13 can be bitten into each other, they do not protrude upward.

The sheet pressing piece 14 cooperates with the curl 7 to clamp the sheet 16 and presses the sheet 16 uniformly, so that wrinkles and unevenness do not occur in the sheet 16. Further, since the other curls 6 uniformly support the sheet 16 with their curved surfaces, wrinkles and unevenness do not occur in these areas as well.

After the bracket 3 is fixed, its angle is adjusted by bending it so as to correspond to the extending direction of the string, etc. A filament such as a string 33 is coupled to the hole 31 serving as the coupling portion.

In the sheet fixing operation described above, first the sheet 16
While pressing , insert the thick part 11 which is the end of the plate part 10 into the dovetail groove 8 on the left side, and then insert the sheet presser part 1 into the dovetail groove 8 on the left side.
Since the sheet 16 is fixed within the support frame 1 by simply tapping the portion 2 from above manually or with a hammer, work efficiency is significantly improved. If the support frame 1 and the sheet presser member 2 are long, it is sufficient to successively tap the sheet several times along the sheet presser member 2.

FIG. 4 shows a perspective view of a greenhouse B equipped with the device of the present invention.

Greenhouse B has a large number of arched pipes 17 erected,
A hard sheet 16 is spread over this pipe 17.

A plurality of support frames 1 are horizontally installed between the respective pipes 17, and are fixed to the support frames 1 via sheet pressing members 2.

A soft sheet 18 is usually spread out in the lower part of the greenhouse B, and when this soft sheet 18 is rolled up via a winder 19, an opening 20 for ventilation is formed.

A bracket 3 is attached to a support frame 1 installed on the side of the greenhouse B.
A wire such as a string 33 is tied to the joint portion, and this wire presses the stretched sheet 16 to prevent unevenness, sagging, bulging, and wrinkles in the sheet 16.

FIG. 5 shows another embodiment of the present invention, in which two support frames 1, 1 are used, a soft sheet 18 is fixed in the left support frame 1, and a soft sheet 18 is fixed in the right support frame 1. A hard sheet 16 is fixed thereto, and a bracket 3 is attached thereto.

The sheet pressing members 2, 2 fitted into each of the support frames 1, 1 are fixed with a cap-shaped spring member 34 to prevent them from coming off upwards.

6 and 7 relate to other embodiments of the present invention,
This shows an example in which the bracket is integrally molded with the sheet pressing member.

That is, in the embodiment shown in FIG. 6, the main body 30a of the bracket 3a is integrally connected or integrally formed with the plate part 10 of the sheet holding member 2, and the length of the main body 30a is equal to the length of the plate part 10. It will be shorter than it is. The bracket 3a is fitted at the same time as the sheet pressing member 2 is fitted to the support frame 1.

Similarly, in the embodiment shown in FIG. 7, the bracket 3b is integrally connected or integrally formed with the plate part 10 of the sheet holding member 2, and the main body 30b has the same length as the plate part 10. A plurality of holes 31 are formed in the main body 30b. In this case as well, the bracket 3b is attached to the support frame 1 at the same time as the sheet pressing member 2 is fitted.

[Effect of idea]

According to the present invention, there are the following effects.

Since the end of the main body of the bracket is attached to the support frame through the plate of the sheet holding member, it is sufficient to provide a gap in the support frame to support the end of the main body. It can be attached even when the plate portion of the sheet holding member is inserted into the sheet and the gap is narrowed.

The main body of the bracket is fixed within the support frame by the restoring force of the sheet presser, and neither the bracket nor the sheet presser moves, so neither the sheet presser nor the bracket moves along the support frame when an external force is applied. The sheet is not rubbed between the bracket and the support frame, and the sheet is prevented from breaking.

The plate main body of the bracket can be bent at any angle after fixation, and the angle can be adjusted freely according to the direction of extension of the strings, etc. to be connected.
