Description

  The present invention relates to a sheet rubbing prevention device in a greenhouse in which a transparent translucent sheet is spread on a roof or a side surface using a sheet fixing device, and in particular, a translucent sheet with a ventilation pipe around which a ventilation sheet is wound. The present invention relates to a sheet rubbing prevention tool that prevents rubbing and tearing.

In this type of conventional greenhouse, a transparent or translucent translucent sheet is spread on a frame made of arch pipes using a sheet fixing device, and plants are grown by transmitting sunlight through the translucent sheet. .
In addition, an opening is provided on the roof, side surface, or wife surface of the greenhouse, and a ventilation device is provided in the opening for ventilation to adjust the room temperature and humidity in the greenhouse.
This ventilation device includes a pipe rotated by a driver and a ventilation sheet wound around the pipe, and ventilates by opening and closing the opening by winding or unwinding the ventilation sheet around the pipe. Is.
However, when the ventilation pipe rolls and winds or rewinds the ventilation sheet, the pipe passes above the sheet fixing device, so that the ventilation sheet wrapped around the pipe or the pipe is attached to the sheet. The translucent sheet pulled out from the upper end of the fixing device is rubbed against the outer surface of the translucent sheet.
If this ventilation operation is repeated for a long period and the rubbing against the translucent sheet is continued, the translucent sheet may deteriorate and be damaged.
For this reason, for example, a sheet rubbing prevention device disclosed in Patent Document 1 has been developed.
This sheet rubbing prevention device is obtained by fitting a friction reducing material made of a prismatic foaming resin material into an opening of a frame material made of a long dovetail frame constituting a sheet fixing device.
According to this sheet rubbing prevention device, even if the pipe for the ventilation device passes while rolling on the sheet fixing device, the light transmitting sheet is held by the sheet fixing device only by contacting the friction reducing material. It is possible to prevent the translucent sheet from rubbing and deteriorating or being damaged.

Japanese Patent No. 5133778

  However, the conventional sheet rubbing prevention device does not have functional defects, but it is desired to improve the following problems.

In other words, the friction reducing material fitted into the opening of the dovetail frame is only formed from the elastic foaming resin material of the prismatic body, so that when fitting into the dovetail frame, the fitting operation is easy. On the other hand, when an external force is applied after fitting, for example, when a pipe for a ventilator rolls and makes contact over a long period of time, when vibration occurs in the frame, or when a strong wind is applied, it deforms easily. However, problems such as falling off the dovetail frame or being damaged occur.
Therefore, since it is necessary to reattach the friction-reducing material that has been removed each time, the operation is troublesome, or it is necessary to form a new friction-reducing material, which is disadvantageous in terms of workability, workability, and economy.
SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet rubbing prevention tool for a vinyl lotus that can be easily and smoothly fitted into a dovetail frame and cannot be easily removed even after external force is applied.

The top surface of the translucent sheet is covered.

According to the present invention, the following effects can be achieved.
A) For example, when a translucent sheet is held by a sheet fixing device mounted on an arch pipe that is a frame on the side of the wife surface, the sheet rubbing prevention device of the present invention is attached to the dovetail frame in the sheet fixing device. If attached, even if a pipe or a roll-shaped ventilation sheet passes over the sheet fixing device, the pipe or the like is prevented from contacting the translucent sheet S.

As a result, rubbing of the translucent sheet can be prevented and its breakage can be prevented.
B) According to the sheet rubbing prevention device of the present invention, since the hollow portion is formed in the trunk portion, the trunk portion is easily compressed and can be easily manually fitted into the dovetail frame, or in the dovetail frame. Can be removed from.
C) Similarly, since the folds are formed along the longitudinal direction on the outer circumferences on both sides of the trunk part, after the trunk part is fitted in the dovetail frame, the folds are not affected by external forces such as vibration and strong wind. It is possible to prevent the groove frame from being pulled out by being caught on the inner periphery or the curled portion.

In particular, when the fold is erected obliquely upward, the crease is improved and the barrel portion can be more securely prevented from coming off.
D) Similarly, since an elastic sheet pressing piece having a spherical or hemispherical cross section projecting laterally along the longitudinal direction is formed on both sides of the upper end of the body part, the sheet pressing piece covers the upper surface of the translucent sheet. The pipe on the ventilator side and the sheet wound around this pipe do not come into contact with each other, so that abrasion due to rubbing of the sheet is prevented, and the durability of the sheet can be improved.
E) Since the sheet pressing piece is formed in a spherical or hemispherical shape, the pipe contacting the sheet pressing piece and the sheet wound around the pipe can move smoothly, and the damage can be prevented.
