Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for opening and closing a part of a side member of a greenhouse used for forcing cultivation of vegetables and flowers.

(Prior Art) In a conventional side member opening / closing device for a vinyl house, a gear box having a manual rotation handle and a rotation output shaft is fixed to a column vertically installed near an end of a hoisting pipe of the vinyl side member. Or the one attached to the same pillar so as to be slidable in the vertical direction. Then, the same rotation output shaft and the end of the same winding pipe are connected, and the same manual rotation handle is rotated to rotate the same winding pipe to open and close the side member.

However, in the conventional opening / closing device, the gear box is fixed to the column or moved as the hoisting pipe moves.

In the gear box fixing method, a universal joint is used to connect the end of the same winding pipe and the same rotation output shaft, but it cannot support the vertical movement of the same winding pipe, so it cannot be used as a vinyl side member. A large force was applied to the part, which could cause it to break.

In the gear box moving method, such drawbacks have been somewhat improved, but since the movement is made by moving the hoisting pipe, it is necessary to sufficiently cope with the movement of the hoisting pipe. I couldn't. That is, since the weight of the gear box is about 5 kg, it tends to fall below the hoisting pipe, it is not possible to completely follow the movement of the hoisting pipe, and also a large force is applied to a part of the vinyl side member. It was added and sometimes damaged. Further, in Japanese Utility Model Publication No. 56-150358 and Japanese Utility Model Publication No. 55-77950, reverse rotation is prevented by a mechanism of a worm and a worm wheel and a mechanism of a ratchet pawl and a detent. Therefore, the weight of the vinyl and the weight of the opening / closing means are applied to these mechanisms, and this mechanism is apt to be damaged.

Also, conventionally, a gearbox is fixed to a pipe erected on a foundation stone buried in the ground, or a pipe with an inner diameter larger than this pipe is attached to the gearbox and mounted on the pipe described above to slide. Was there. For this reason, it takes time to dig a hole for the foundation stone and backfill it.
The cost was also high.

(Problems to be solved by the invention) The problem to be solved by the present invention is that the mounting work is easy,
An object of the present invention is to provide a side member opening / closing device for a vinyl house, which is low in cost, can be opened and closed easily and smoothly, and does not cause damage to the vinyl side member or the like.

(Means for Solving the Problems) The gist of the present invention which has solved the above problems is to provide a long rotatable hoisting pipe for hoisting a lower end of a vinyl side member horizontally on a side portion of a vinyl house. , A gear box with a manual rotation handle and a rotation output shaft is slidably attached to a column vertically installed near the end of the same winding pipe, and the same rotation output shaft is connected to the end of the same winding pipe. In addition, the other end of a cord-shaped body such as a rope or wire having a predetermined length whose end is locked to a support fitting mounted on the upper part of the column is locked to the outer peripheral surface of the rotation output shaft. It is located on the side member opening / closing device of a greenhouse.

(Operation) In the side member opening / closing device for a greenhouse according to the present invention, the rotation output shaft is rotated by rotating the manual rotation handle of the gear box, and the hoisting pipe connected to the rotation output shaft is connected. It is designed to rotate. Winding the lower end of the vinyl side member by rotating the winding pipe,
It rewinds and opens and closes.

The gear box is vertically slidable with respect to the column, and the supporting metal fitting on the column upper part and the rotation output shaft of the gear box are locked by a rope-like wire-shaped body. Therefore, when the rotation output shaft rotates, the cord-shaped body such as the rope is wound around the rotation output shaft, and the gear box moves upward as the rope-shaped body such as the rope is wound. Will be done. If the length of the rope-shaped body such as the rope is adjusted to the length of the vinyl side member, the gear box will rise as the vinyl side member is rolled up. It will not be damaged by applying a large force.

That is, the gearbox is also designed to move up and down according to the vertical movement of the hoisting pipe when the vinyl side member is opened and closed. I'm supposed to get it. Therefore, the gear box can be moved up and down without applying an unreasonable force to the hoisting pipe, the vinyl side member, or the like.

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

FIG. 1 is a partially cutaway perspective view showing an embodiment, and FIG. 2 is an explanatory view of the same operation.

In the side member opening / closing device of the vinyl house of this embodiment,
On the side part of the vinyl house (1), a long rotatable hoisting pipe (3) for hoisting the lower end of the vinyl side member (2) is horizontally provided, and a manual turning handle (4) and turning are provided. A gear box (6) having an output shaft (5) is vertically slidably mounted on a column (7) to connect the rotating output shaft (5) and the end of the hoisting pipe (3), and further to the column (7). ) A support metal fitting (8) mounted on the upper part and the outer peripheral surface of the rotary output shaft (5) are locked by a rope (9). Since the support metal fitting (8) is detachably attached to the upper part of the column (7), the gear box (6) can be easily attached and detached.

When opening the vinyl side member (2) of the vinyl house (1), the manual rotation handle (4) is turned to rotate the hoisting pipe (3) to wind up the vinyl side member (2). There is. The hoisting pipe (3) rises as the vinyl side member (2) winds up, and the gear box (6) also rises while winding the rope (9) around the rotation output shaft (5). Has become. When closing the vinyl side member (2), the manual turning handle (4) is turned in the opposite direction to lower the hoisting pipe (3) and the gear box (6).

Therefore, since the hoisting pipe (3) and the gear box (6) both go up and down, applying an unreasonable force to a part of the hoisting pipe (3) and the vinyl side member (2). It will not be damaged.

Further, since the hoisting pipe (3) and the gear box (6) move together, the opening / closing operation of the vinyl side member (2) itself can be performed easily and smoothly.

Since the weight of the gear box (6) is supported by the rope (9), the end of the hoisting pipe (3) will not be pulled down and deformed even after a long period of time.

In this embodiment, since the pipe of 19φ to 32φ can be used as the support pillar (7) only by inserting it into the ground to some extent, the price is low and it does not take time and effort. Therefore, it is very convenient for the user.

(Effects of the Invention) According to the present invention, the installation work is easy, the cost is low, the opening and closing operation can be performed easily and smoothly, and the side members of the vinyl house can be opened and closed without damaging the vinyl side members. A device can be provided.
