 The device of the present invention comprises a left and right sliding door body, a sliding door section 10 for moving the sliding door body to the left and right, a wire section 20 connected to the sliding door body to ensure the interlocking of the left and right sliding doors, and automatically closing the opened sliding door. A return section 30 for controlling the return operation and a damper section 40 for controlling the return operation.

As shown in FIG. 1, the sliding door section 10 has a pair of sliding doors including a right sliding door 11 and a left sliding door 12 disposed in a part of an agricultural greenhouse. Rails 13 for guiding the sliding doors 11 and 12 to the left and right are arranged above the sliding doors 11 and 12. Rollers 14 and 15 for rolling with respect to the right sliding door 11 are provided on the rails 13, and the left sliding door 12 is provided for the left sliding door 12. Rollers 16 and 17 are provided respectively. Then, as shown in FIG. 2, the roller 14 and the sliding door 11 are connected to the roller 14 by a connecting fitting 14a which is curved in a substantially U-shape so that the axes thereof are vertically aligned. Similarly, the rollers 15, 16 and 17 are connected to the sliding doors 11 and 12 in the vertical direction by connection fittings 15a, 16a and 17a. That is, the connecting fitting 14a is formed to be curved with the rail 12 interposed therebetween so that there is no deviation of the axis in the vertical direction between the sliding door 11 and the roller 14 for guiding the sliding door. The U-shaped connecting bracket 14a may be not only a form in which an iron piece is curved but also a form in which a steel plate is combined with a U-shape by screws, and in this sense, the U-shaped connecting fitting 14a is formed in a "substantially" U-shape. The number of the rollers is such that two rollers 14 to 17 are arranged for one sliding door, but the present invention is not limited to this.

In the sliding door section 10, a pulley 22 is disposed above the rail end of the right sliding door 11 and a pulley 23 is disposed above the rail end of the sliding door 12 on the opposite side, with the roller 14 at one end as a base end. Finally, the wire 21 is wound around the roller 14 at one end of the right sliding door 11 as a terminal. It is desirable that the wire 21 is wound in the shape of a figure 8 in the middle, and tension rollers 24 and 25 are interposed as necessary. Then, the rollers 14 to 17 are fixed to the wire 21. First, the base end of the wire 21 is fixed to the roller 14, and after turning by the pulley 22, the roller of the left sliding door 12 is fixed. After being fixed to the right and left sliding doors 11 at the end thereof, they are fixed to the rollers 14 of the right sliding door 11 at the end. That is, when the right sliding door 11 is opened by being pulled to the right, the roller 14 slides to the right with the movement of the sliding door 11, but the wire 21 fixed thereto is pulled and turns through the pulleys 22 and 23. In accordance with the turning of the wire 21, the left sliding door 12 is moved to the left by the connecting hardware 16a, 17a via the rollers 16, 17 fixed to the wire 21, that is, simultaneously opened to the left. I do.

As shown in FIG. 3, the roller 14 and the wire 21 are fixed to each other by arranging two washers near the rotation axis of the roller 14 so that the wire 21 is sandwiched therebetween and a set screw 14b is provided from the outside. To stop. The same applies to the rollers 15 to 17.

The return portion 30 is provided with a return spring 31 having a built-in spring and the like in the vicinity of the rail end opposite to the right sliding door 11, from which a drawstring 32 is extended, and a base end thereof is provided. Is fixed to a part of the right sliding door 11. In conjunction with the opening of the right sliding door 11, the drawstring 32 is pulled, and the pulling force pulls the spring of the return spring 31. Conversely, when the opening force is released, the spring of the return spring 31 operates to operate the right sliding door. 11 is pulled back. At the same time, the left sliding door 12 moves in the closing direction in conjunction with the closing movement of the right sliding door 11, so that the entire door is automatically closed.

As shown in FIG. 4, the damper part 40 is connected to a part of the upper end of the right sliding door 11, and a rack 42 is provided as an operating piece that is linked to the movement of the sliding door, and a pinion meshed with the rack 42. The dampers 41 combined with the 43 are connected. As the damper 41, there are a type utilizing the viscosity of oil, an electromagnetic control type, and the like, and any of them may be used. The damper 41 is a braking mechanism that does not exert a braking force when the sliding door moves in the opening direction, but operates as a brake when moving in the closing direction. This is because when the sliding door is opened, the sliding door may be opened all at once. However, when the sliding door is closed too quickly when the return operation is started and the return unit 30 starts to operate, the worker may be pinched by the sliding door. There is a danger of avoiding this.

Further, a biasing mechanism 50 for preventing a gap from being formed between the left and right sliding doors is provided at the boundary between the sliding doors. As shown in FIG. 5, a hook 51 is fixed to a part of the wire 21, a spring 52 is interposed from the hook 51, and the end of the spring comes in contact with a part of the connecting fitting 14 a of the sliding door 11. And an elastic body such as rubber is applied to the contact surface.

Next, the operation of the device of the present invention will be described. First, in the case of using an agricultural house, when a worker or a tourist picking strawberries tries to enter or exit the house, for example, the right sliding door 11 is pulled to the left in the drawing. Then, with the movement of the right sliding door 11, the roller 14 slides to the right, the wire 21 fixed thereto is pulled, and the wire 21 turns in a figure eight shape via the pulleys 22 and 23. In accordance with the turning, the rollers 16 and 17 fixed to the wire 21 move to the opposite side, and the left sliding door 12 moves to the left by the connecting fittings 16a and 17a connected thereto. In other words, simultaneously with the opening of the right sliding door, the left sliding door is automatically opened in conjunction with both.

At this time, since the roller 14 and the sliding door 11 are connected to each other by the connecting fitting 14a curved in a substantially U-shape, the axes of the rollers 14 and the sliding door 11 are vertically aligned, and the sliding door 11 is moved downward. The movement is extremely smooth without swinging with respect to the ra. This movement is the same for the rollers 16 to 17, and the verticality is maintained between the sliding door and the rollers as a whole, and the opening and closing operations are smooth.

Therefore, workers, strawberry picking tourists, etc. can enter the house to perform cultivation work, strawberry picking, and the like. Particularly, when entering and exiting a work vehicle, an entrance space is provided by a sliding door that opens left and right. It is widely secured and easy to get in and out.

When the force of pulling the opened sliding door is released, the spring of the return spring 31 pulled by the drawstring 32 interlocked with the right sliding door 11 is operated, and the right sliding door 11 is pulled to return to the original direction. Moving. At the same time, in conjunction with the closing movement of the right sliding door 11, the left sliding door 12 also moves in the closing direction, and the entire door is automatically closed.

At this time, when the sliding door moves in the opening direction, the damping force of the damper 41 does not work. When the sliding door moves in the closing direction, on the other hand, the damper 41 exerts a braking action by viscous oil or electromagnetic force. It closes slowly, that is, there is no danger of the arm being caught in the sliding door.

Further, at the boundary between the left and right sliding doors, the urging force of the spring body 52 sandwiched between the hooking pieces 51 fixed to a part of the wire 21 acts, so that one of the sliding doors is pushed in the closing direction and slightly pushed. No gaps are created.

[0020]

[Effect of the invention]

 Based on the above configuration and operation, the present invention makes it easy for workers and strawberry picking tourists to get in and out of the house by opening and closing one sliding door and automatically opening and closing the other sliding door. At the same time, the opening and closing movement of the sliding door is extremely smooth without swinging since the verticality is maintained between the roller and the sliding door. Further, when the sliding door moves in the closing direction, the braking force by the damper is exerted, and the danger of the arm or the like being pinched by the sliding door is avoided. Furthermore, at the boundary between the left and right sliding doors, the urging force of the spring body sandwiched between the latching pieces acts to prevent the occurrence of a gap between them, thereby exhibiting effects such as perfecting the greenhouse effect. It is a highly conceived device.
