Description

[Detailed Description of the Invention] (Industrial field of application) The present invention enables more effective cultivation by adjusting the cultivation environment in a cultivation facility for vegetables, mushrooms, flowers, etc. that require shading. The present invention relates to a shading curtain for a greenhouse.

(Prior Art) Currently, a curtain or sheet with a hook clasp is used to adjust the cultivation environment of a cultivation facility (greenhouse etc.) for easy attachment and detachment. Since such a method was inconvenient, in order to improve it in a better condition, Japanese Patent Application No. 63-106083 or Japanese Patent Application No. 1-1-1
25836 etc. have been considered.

(Problems to be solved by the invention) However, in such a method, even if it can be wound, it cannot be wound evenly and is uneven, and it is difficult to stretch in the same state. Since they are installed side by side, etc., the fasteners and other mounting materials and processing costs are high, which is uneconomical and is very inconvenient for implementation or use.

(Means for Solving Problems) The present invention eliminates such inconvenience and enables a long wide area to be covered with a single sheet.

That is, one of the first fasteners is provided on the attachment frame and the other is provided on the curtain, one of the second fasteners is provided on the auxiliary frame provided at an appropriate position below the attachment frame, and the other is provided at an appropriate position on the back surface of the curtain in a detachable manner. An opening / closing device for freely winding the second fastener and opening / closing the second fastener is provided.

(Function) By thus providing the first fasteners on both ends of the curtain and further providing the second fasteners on the back surface of the curtain to fix the curtain, the swinging of the curtain due to wind or the like is suppressed, and the greenhouse is especially cultivated. It is possible to suppress the swinging of the curtain in the lateral direction with respect to the slope of the roof by the second fastener, and it is possible to easily attach and detach even the curtain of a long object and wind it up easily, and it is possible to adjust the environment of the cultivation facility. .

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 is a mounting frame made of an appropriate material and having an arbitrary cross section (the figure shows the case of a square), and the mounting material is assembled into a frame shape.

Reference numeral 2 denotes a curtain having an appropriate length in which first fasteners 4 protruding from the first slider 3 are provided on both sides, and the other of the first fasteners 4 is attached to a predetermined position (usually the vertical direction) of the attachment frame 1. ing.

Reference numeral 5 is a second fastener projecting a second slider 6, and an auxiliary frame 7 having an arbitrary cross section in which a plurality of fasteners are provided in parallel on the back surface of the curtain 2 at appropriate intervals and the other is provided below the mounting frame 1 at appropriate intervals.
Installed on.

Reference numeral 8 is a winding shaft, and a fitting recess 9 for fitting in a rectangular tube shape at the end portion.
Is provided on the rear surface of the curtain 2 so as to be rotatable, and is attached to the lower end of the curtain 2 on the winding shaft 8 so that the winding shaft 8 can be rotated and wound.

Numeral 10 is a slider guide having one end for fitting a bearing and the other end bent in an arbitrary direction. A hooking hole 11 is formed at the bent tip, and is provided at both ends of the winding shaft 8 via bearings so as to be freely rotatable. At the same time, the first slider 3 is fitted and locked in the hook hole 11.

Reference numeral 12 is an accelerator wire, one end of which is fitted into the fitting recess 9 to allow the winding shaft 8 to rotate freely by electric or manual operation.

Reference numeral 13 denotes an entire opening / closing device for the second fastener 5, 14 is a pulley, and a wire 16 is provided at one end of the auxiliary frame so as to be free to rotate by a support shaft 15 and connects an arbitrary position to the second slider 6.
It is possible to move left and right manually or electrically.

In use, if the product is long, the curtain 2 is wound in the lateral direction to form a scroll, so the first fastener 4 at one end of the wound curtain 2 is fitted and closed, and one end of the curtain 2 is attached to one of the mounting frames 1. After fixing to, as shown in FIG.
The curtain 2 is expanded laterally with respect to the slope of the roof and the second fastener 5 is closed to cover the roof.

Finally, the first fastener 4 at the other end of the curtain 2 is closed to complete the installation of the curtain 2.

Then, slider guides 10 are provided at both ends of the take-up shaft 8 through bearings so as to rotate freely, and the first slider 3 and the hook holes are provided.
11 is fitted and locked, and the accelerator wire 12 is fitted into the fitting recess 9.

And if you want to wind the curtain, start with wire 16
After moving the second slider 6 to remove the second fastener 5 to a predetermined position, when the winding shaft 8 is rotated to start winding the curtain 2, the slider guide 10 pushes the first slider 3 Remove the first fastener 4 and wind it on the winding shaft 8.

Next, when rewinding for light shielding, the accelerator wire 12
Then, when the winding shaft 8 is reversed and the curtain 2 is returned,
The first slider 3 is moved by the slider guide 10 to close the first fastener 4, and the winding shaft (8) comes back to the original position to cover the roof with the curtain 2 and the rewinding ends and the winding shaft 8 Stop rotating.

After that, move the second slider 6 with the wire 16
Close the zipper 5 and stretch the curtain 2 in the same state.

It should be noted that both ends of the curtain 2 may be provided as in Japanese Patent Application No. 1-56005 so that the curtain 2 can be moved closer or wider without being wound.

(Effects of the Invention) As described above, the present invention requires less fasteners and mounting parts because the curtain can be made of one piece, and the curtain of one piece is pulled at an appropriate pitch regardless of the length of the curtain. It has many features such as curbing of the curtain due to, and opening and closing of a wide and wide area can be easily set up in the same state, and winding can be done simultaneously and the irradiation area and time can be adjusted freely and quickly. It is a very excellent device.
