Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple house opening / closing apparatus for winding and rewinding a resin sheet of a simple house constituted by covering a resin sheet and opening and closing the resin sheet.

[0002]

2. Description of the Related Art Generally, so-called house cultivation, in which agricultural products such as vegetables and fruits are cultivated in a house, has become widespread. In this house cultivation, for example, a skeleton that forms an internal space with a metal pipe is constructed, and a simple house configured by coating the skeleton with a resin sheet is used. In this simple house, a simple house opening / closing device that opens and closes by winding and unwinding the resin sheet is provided to control the temperature, humidity and ventilation in the house, so that an optimum environment for growing crops can be created.

Conventionally, as this kind of simple house opening / closing device, for example, as shown in FIG. 8, a pair of bar-shaped rails 1 attached to the left and right in parallel at a predetermined interval and slidably provided on each rail 1 are provided. The vehicle includes a moving body 2, a shaft 3 rotatably mounted between the moving bodies 2, for winding and rewinding the resin sheet S, and a handle 4 provided on the moving body 2 and rotating the shaft 3. The resin sheet S is coated by hanging down from above the framework (not shown), and the lower end thereof is wound around the shaft 3, and is wound up from below and opened. When the shaft 3 is rotated in the winding direction, the resin sheet S is fixed to the skeleton at the upper end. To rise. On the other hand, when the shaft 3 is rotated in the rewinding direction, the resin sheet S is rewound from the shaft 3 and the moving body 2 slides down the rail 1 by its own weight. Thus, the resin sheet S is opened from the lower side of the house, and the degree of opening is adjusted from the lower side to perform ventilation (for example, Japanese Patent Application Laid-Open No. H8-17293).
No. 3 publication).

[0004]

By the way, when growing the crops, if the resin sheet S is opened from the lower side of the house and the opening is adjusted from the lower side to ventilate, the resin sheet S is lowered from the beginning when the resin sheet S is opened. Since the cold air on the side enters the house, it may adversely affect the crops. Therefore, there is a demand to open the resin sheet S from the upper side of the house and adjust the opening from the upper side to perform ventilation. However, in the above-mentioned conventional simple house opening / closing device, there was a problem that the resin sheet S could not be opened from above the house. The reason is that the resin sheet S is opened from the upper side of the house as shown in FIG.
When the resin sheet S is opened even when the upper end of the resin sheet S is wound around the shaft 3, the resin sheet S
The moving body 2 can be lowered by applying tension to
When closing the resin sheet S, even if the shaft is rotated in the rewinding direction, only the resin sheet S is rewound, and the moving body cannot move up the rail 1. Can no longer be closed. Further, in the conventional open / close device for a simple house, the shaft 3 is easily bent downward, and this bending may hinder the movement of the moving body 2 and the winding and rewinding may not be performed smoothly. There was a problem.
In particular, in the case of a large house having a shaft 3 of several tens of meters in length, the problem of the bending is large, and a situation may occur in which the apparatus cannot be installed substantially.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has a structure in which a movable body can be moved up and down in conjunction with rotation of a shaft so that a resin sheet can be opened from above. In addition, an object of the present invention is to provide a simple house opening / closing device capable of smoothly winding and unwinding a resin sheet by suppressing bending of a shaft.

[0006]

The technical means of the present invention for solving such a problem is to wind the resin sheet of a simple house constructed by covering a skeleton forming an internal space with a resin sheet. In a simple house opening / closing device that rewinds and opens and closes, a pair of rails that are attached to the skeleton in parallel at predetermined intervals, a movable body that is reciprocally movable on each of the rails, and a rotation between the pair of movable bodies. A shaft erected and rotated to take up and rewind the resin sheet; a rod erected between the pair of moving bodies in parallel with the shaft so as to be rotatable; and a moving body provided on the moving body. A rotation mechanism for moving the shaft and the rod in conjunction with each other while moving relative to the rail; and a rotation mechanism provided between the pair of rails and driven by the rod. A shaft support mechanism for supporting a shaft, wherein the shaft support mechanism includes a guide rail provided substantially parallel to the rail, a chain stretched along the guide rail, and the guide rail. A base body movably provided and supported by the rod and moved together with the moving body; a sprocket provided on the base body and driven by the rod to rotate and mesh with the chain; And a support member that has a gap provided to allow the resin sheet to be wound and unwound with respect to the shaft and that encloses the resin sheet wound around the shaft and supports the shaft via the resin sheet. I have. Here, the chain and the sprocket of the shaft support mechanism have a wide concept including a timing belt and its pulley, that is, any type may be used as long as it is used in a meshing transmission mechanism.

Thus, for example, when the upper end of the resin sheet is wound around the shaft and the resin sheet is opened from above, when the resin sheet is opened, the shaft is rotated in the winding direction. The moving body is lowered by the rotating mechanism while being wound up.
On the other hand, when the shaft is rotated in the rewind direction when closing the resin sheet, the resin sheet is rewound from the shaft, and the moving body is raised by the rotating mechanism.
In this case, the moving body moves in conjunction with the rotation of the shaft. Therefore, the resin sheet is wound up and opened from the top to the bottom, and the resin sheet is rewound and closed from the bottom up, which was not possible conventionally. Is realized.

In winding and rewinding the resin sheet, the shaft support mechanism always supports the shaft. In the shaft support mechanism, when the rod rotates due to the movement of the moving body, the sprocket meshes with the chain and rotates, so that the base moves together with the moving body. In this case, the shaft is supported by the shaft support mechanism via the wound resin sheet and the supporting member that encloses the resin sheet, so that the shaft is prevented from bending. Therefore, the winding and rewinding of the resin sheet is performed smoothly. In particular, the load of the shaft is supported by the guide rail via the support member and the base body, and is supported by the chain via the support member, the base body and the sprocket.
Since the load on the shaft is shared and supported by the guide rail and the chain, the shaft is reliably supported and bending is prevented. Further, since the base body moves by the engagement of the sprocket and the chain, the amount of movement is made constant, so that the upper and lower touches of the shaft are suppressed, so that the winding and rewinding of the resin sheet is also smoothly performed at this point. Furthermore, since the resin sheet is enclosed and held by the support member, the resin sheet is less likely to shift to the left and right, so that the bias due to the winding of the resin sheet is prevented,
Also in this regard, the winding and rewinding of the resin sheet is performed smoothly.

Further, if necessary, the base body is provided with a set of rollers for holding the guide rail and rolling on the guide rail. At the time of movement of the base body, the set of rollers rolls on the guide rail while sandwiching the guide rail, so that the base body travels smoothly with respect to the guide rail, and the movement is smoothly performed. Further, if necessary, the base body is provided with a pressing roller for pressing the chain against the sprocket. When the base body is moved, the chain is pressed against the sprocket by the pressing roller, so that the chain is prevented from coming off the sprocket and the chain is skipped, and the base body is smoothly moved. Furthermore, if necessary, the support member is formed by bending a plate-shaped member, and is opened to the front side to enclose the resin sheet wound around the shaft; and the enclosing portion. And a guide piece extending to the front side of the base body and supporting and guiding the resin sheet immediately before being wound on the shaft. Since the guide sheet supports and guides the resin sheet immediately before it is wound on the shaft, the winding and rewinding of the resin sheet can be performed smoothly, and the resin sheet can be reliably contained in the enclosing section.

If necessary, the rail is constituted by a rack, and the moving body is provided with a moving body main body slidably arranged along the rack. The gear mechanism includes a pinion gear rotatably supported by the moving body and meshing with the teeth of the rack, and a driven gear rotatably supported by the moving body and meshing with the pinion gear. . Since the rack and the pinion gear mesh with each other, there is no slippage, no vertical displacement occurs between the left and right moving bodies, the moving bodies are surely moved, and the resin sheet is smoothly wound up and rewound. In this case, an auxiliary gear meshing with the teeth of the rack is rotatably supported on the movable body, and the movable body is cooperated with the pinion gear and the auxiliary gear to sandwich the rack, and the back of the rack. It is effective to rotatably support a pair of rollers for rolling the roller. The moving body is securely held on the rack by the pinion gear, the auxiliary gear, and the roller, and stability is achieved, and the movement is smoothly performed by the roller.
