Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a fixing device for vinyl sheets, and more specifically, to an improvement of a fixing device for vinyl sheets in greenhouses and other greenhouses. .

[Prior art and issues to be solved]

Generally, greenhouses and other greenhouses have a channel-shaped support frame fixed to the frame of the house body.
It is constructed by covering the outer surface of the house body with a transparent vinyl sheet and then fixing this vinyl sheet along a support frame.

By the way, as means for fixing such a vinyl sheet along the support frame, for example,
As shown in FIG. 7, the vinyl sheet A was pushed into the opening recess of the support frame 1 via the band-shaped holding member 3, and the corrugated filament 5 was fitted into the opening recess and fixed by pressure. Stopper (Jikko 49)
-41067) etc. are used.

However, with this type of fixing means, because the cross-sectional shape of the support frame is narrow at the opening and wide at the bottom, the fitted corrugated filaments become hot under the influence of direct sunlight, and the vinyl sheet deteriorates in this area. Various problems have been pointed out, including not only the fast progress but also the fact that the vinyl sheet is rubbed and damaged when the corrugated filament is fitted into the opening recess.

[Means for solving problems]

Therefore, in this invention, by integrally forming light-shielding tongues set to a predetermined width on both sides of the band-shaped holding member used in conventional fixing devices, the vinyl sheet can be prevented from deterioration and damage and can be made durable. This is an attempt to improve sexual quality.

In this case, if one or more grooves are provided extending along the longitudinal direction of the strip-shaped holding member, the pushing operation of the strip-shaped holding member can be easily performed.

Further, it is preferable that the light-shielding tongue piece is formed in the form of a sheet, but the light-shielding tongue piece and the band-shaped holding member may be formed to have substantially the same thickness and a groove is provided at the boundary between them. good.

[Effect]

In the fixing device according to this invention, since the tongue piece is interposed between the vinyl sheet and the wavy filament that is twisted and fitted into the opening recess of the channel-shaped support frame, the vinyl sheet is not damaged.
Further, the wavy filament fitted into the opening recess is reliably shielded from direct sunlight by the overlapping of the tongues on both sides of the belt-shaped holding member.

〔Example〕

Next, preferred embodiments of the fixing device according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, the fixing device 10 according to the present invention includes an opening recess 14 of a support frame 12.
The holding member 16 is attached to the holding member 16, and the corrugated filament 18 presses and fixes the pressed portion a of the vinyl sheet A pushed into the opening recess 14 by the holding member 16.

That is, the holding member 16 has a belt-shaped main body 20 that is made of flexible synthetic resin that has been given light-shielding properties by coloring or the like, and that is set to be slightly wider than the opening width of the opening recess 14 of the support frame 12. , a groove 22 is provided along the longitudinal direction of the center of the belt-like main body 20, and sheet-like tongues 24, 24 having a predetermined width are integrally provided on both sides of the groove (see FIG. 3). ). In this embodiment, the case where the groove part 22 is provided in the belt-like main body 20 is illustrated, but it goes without saying that this groove part 22 can be omitted. It is preferable to integrally form the pieces 24, 24 because it can be manufactured at low cost.

Further, the wavy filament 18 is formed by bending a wire or steel wire of a predetermined diameter and has a shape in which trapezoids protrude alternately along the longitudinal direction, as in the conventional case, and has a shape in which trapezoids protrude alternately along the longitudinal direction. 14 by twisting it left and right.

Fixing device 10 according to the present invention configured as described above
Support frame 12 for vinyl sheet A using
When fixing on vinyl sheet A, first
The band-shaped main body 20 of the holding member 16 is brought into contact with the holding member 16 along the position corresponding to the frame opening recess 14, and then, while pressing the center part of the band-shaped main body 20, the vinyl sheet A is pushed into the opening recess 14 from the end along with part a of the vinyl sheet A. go. In this case, although the strip body 20 is slightly wider than the opening width, it is easily bent in the groove 22, so that not only can the pushing operation be performed smoothly, but also the thickness of the tongue pieces 24, 24 and the strip body 20 can be easily bent. Due to the difference, it can be set without shifting left or right.

When the work of pushing part a of the vinyl sheet A into the opening recess 14 together with the holding member 16 is completed, next, the end of the wavy filament 18 is inserted into the sheet-like tongue piece 2.
By contacting the inner wall of the opening recess 14 from above 4, 24 and sequentially inserting it while twisting from side to side, the portion a of the vinyl sheet is pressed and fixed via the sheet-like tongue pieces 24, 24, and then the sheet-like tongue piece The pieces 24, 24 may be appropriately overlapped as shown in FIG.

Therefore, the sunlight that has hitherto been directly irradiated onto the wavy filament 18 is now irradiated by the overlapping sheet-like tongue pieces 24,
Since it is shut off by 24, an extreme temperature rise is prevented. Further, the operation of pushing the holding member 16 into the opening recess or positioning the holding member 16 is also performed using the belt-shaped main body 2.
Not only can this be done easily due to the presence of the grooves 22 of 0, but the vinyl sheet A is pressed against the wavy filaments 18 via the sheet-like tongue pieces 24, 24, and the vinyl sheet A is pressed against the wavy filaments 18 corresponding to the troughs of the wavy filaments 18. Since discontinuous portions are also held continuously by the belt-like main body 20, loosening and wrinkles due to repeated loads such as wind can be prevented. Even when the vinyl sheet is inserted into the vinyl sheet, there is no problem such as direct contact between the corrugated filaments 18 and the vinyl sheet, resulting in damage.

In addition, FIG. 4 shows a holding member in a fixing device according to the present invention, in which the belt-like main body 20 and the tongue pieces 26, 26 of the holding member 16 are set to have substantially the same thickness, and grooves 28, 28 are provided at the boundaries between them. Another embodiment, in which the holding member is attached to the strip body 2
Since the vinyl sheet A can be bent freely from the groove 22 or the grooves 28, 28, it will not shift left or right as described above, and the vinyl sheet A can be protected more reliably.

[Effect of idea]

As mentioned above, according to the fixing device according to the present invention, the temperature increase due to sunlight on the wavy line fitted in the recess is prevented by covering it with the light-shielding tongue piece. Not only can it delay deterioration and improve durability, but it also makes it easier to fix the vinyl sheet, and it also eliminates the risk of damaging the vinyl sheet when fitting the corrugated wire into the opening recess of the support frame. There is no
Furthermore, since the wavy filaments press and fix the vinyl sheet through the tongue piece of the holding member, it has various advantages such as being able to securely fix it without causing loosening or wrinkles, and its practical effects are extremely high. big.

Although the preferred embodiment of the fixing device according to the present invention has been described above, the present invention is not limited to this embodiment. You can make it even smoother (see Figure 5), or make one tongue of the holding member a little thicker and attach it to the opening recess so that the thick tongue covers the other tongue to make the set more beautiful and to prevent airflow. To prevent the flap of the tongue due to such things (see Figures 6a and 6b),
Furthermore, it goes without saying that various modifications can be made without departing from the spirit of the present invention, such as by fitting the wavy wire into the recess and then bonding the tongues on both sides to each other by appropriate means.
