Description

[Detailed Description of the Invention] The present invention relates to a vinyl film hanging device suitable for a vinyl house, particularly a vinyl house with a large eave height.

Vinyl greenhouses are widely used for cultivating and growing various crops. In this type of vinyl house, a vinyl film is hung from a roof frame made of pipes, etc., and the work of hanging and removing the vinyl film is currently almost entirely manual. Also, especially cherry houses (for rain protection)
etc., the height of the eaves is about 5 to 7 meters, and the work of applying or removing vinyl film from the roof is extremely dangerous because it requires work at heights with poor footing. In addition, such work requires manpower and time, and in addition, the footing is poor and there is a danger that the vinyl film may be blown away by wind pressure during the work, making it difficult to perform the work on rainy or windy days. There is. In such cherry greenhouses, the vinyl film for the roof is only used for about two months during the fruiting period, so the vinyl film must be hung and removed every year, which is a major drawback in using this type of greenhouse. It was something that had become familiar to me.

The present invention was devised in view of these conventional difficulties, and aims to provide a device that can hang vinyl film with simple operation without requiring work on the roof.

Therefore, in the present invention, flanges are formed on both sides of the upper end of the groove-shaped part, and a downwardly bent part is formed at the end of the flange part, so that the cross-sectional shape is hat-shaped, and the roof cross-section is shaped like a hat. The trolley body is composed of a plurality of guide rails arranged at intervals, and a trolley body to be moved by being pulled on the guide rails via a rope or chain positioned in a groove-shaped portion of the guide rails. The body includes a plurality of rollers to be rolled on both flanges of the guide rail, and a plurality of rollers located on the lower surface side of both the flanges,
An engaging member that can engage with the outer surface of the grooved part and the flange part of the guide rail to prevent the trolley body from shifting laterally and lifting up, and a fixing means that removably fixes the rigid member attached to the vinyl film side. The end portion of the vinyl film is fixed to such a trolley body and moved on a guide rail, so that the vinyl film can be attached and detached.

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

Bridge the ends in an inclined manner. This guide rail 17
The guide rail 1 has the same cross-sectional shape as the guide rail 1.

Then, the trolley body 2 is positioned on each guide rail 17 in a movable state, and
The tow rope 12 from the winding winch 14 is connected to the guide rail 1 on the roof and the guide rail 17 above.
The trolley body 2 is connected to the trolley body 2 through the groove-shaped portion thereof, and is held therein. On the other hand, a rigid member 18 such as a pipe is installed in advance along the edge of the vinyl film F, and is fixed to a clip 19 serving as the fixing means 7 of each trolley body 2, as shown in FIG.

In this state, the winding winch 14 starts winding the tow rope 12, and as a result, the plurality of trolley bodies 2 enter the guide rail 1 with the vinyl film F behind them, and the guide on the other side Move to the end of the rail (position indicated by P in the figure). The end of the guide rail 1 is provided with suitable stop means. When the trolley body 2 reaches the above-mentioned position P, the entire roof is covered with the vinyl film F, and the work is completed by fixing and restraining the vinyl film F to a frame member or the like by appropriate means. Note that the guide rail 17 and the traction rope 12 are removed after the work is completed.

In addition, when removing the vinyl film F stretched as described above, the trolley body 2 is moved in the original direction, but for this purpose, a separate pulling rope or the like is connected to the trolley body 2 in advance. It is preferable that the pulling rope be positioned within the groove-shaped portion 100 of the guide rail 1 so as to follow the trolley body 2 that moves when the vinyl film is stretched.

In the above-mentioned work, a strong upward force is applied to the trolley body 2 due to wind pressure applied to the vinyl film F following the rear part of the trolley body 2, but the engaging member 6 prevents the trolley body from lifting up and coming off the wheels properly. Prevented.

FIG. 9 shows a preferred embodiment for restraining a vinyl film F placed on a roof. In other words, in a general vinyl greenhouse,
In order to stretch the vinyl film covering the roof tightly against the frame material, a rope is strung across the width of the roof, and the rope is used to push the vinyl film downward. Conventionally, such a rope was spanned manually, but when using the device of the present invention, the end of the rope is attached to the trolley body 2, and the rope is made of vinyl. The vinyl film F is pulled together with the vinyl film F by the trolley body 2 so as to be positioned above the film F, and with the vinyl film F covering the entire roof as described above, the vinyl film F is pulled from the ground by pulling the rope. is narrowed down into the groove-shaped portion 100 of the guide rail.
