[0004]

Therefore, in the conventional sliding door device, the drive device and the braking device are different types of devices having completely different structures and principles. Therefore, in the past, when manufacturing a sliding door device including a drive device and a braking device, the spiral spring type device and the air cylinder type device are manufactured or purchased as a part of the sliding door device,
Since these are incorporated into the sliding door device, the number of types of devices that must be prepared increases, and the management thereof becomes complicated.

An object of the present invention is to provide a sliding door device which can reduce the types of devices prepared as a drive device and a braking device.

[0006]

A sliding door device according to the present invention comprises a stationary member, a sliding door body movable with respect to the stationary member, a drive device for moving the sliding door body, and the moving sliding door. In a sliding door device having a braking device for applying a braking force to a main body, the drive device and the braking device have the same structure or substantially the same structure.

In this sliding door device, the fact that the drive device and the braking device have the same structure or substantially the same structure includes both the case where the structure is completely the same and the case where the basic structure is the same. Even when the principle of generating the force acting on the sliding door body is the same, the structures of the drive device and the braking device are the same or substantially the same.

According to this sliding door device, since the driving device and the braking device have the same or substantially the same structure, both the driving device and the braking device to be incorporated into the sliding door device by the same device in principle. Therefore, the number of types of devices that must be prepared can be reduced as compared with the related art, and the management thereof can be facilitated.

The drive and braking devices are
Any structure may be used as long as the structures are the same or substantially the same and the principle is the same.For example, a spring type device using accumulated spring force, an air cylinder type device using pressing force of a piston, or an electromagnet A linear motor type device or the like that uses a suction force and a repulsive force may be used.

Further, the positions for arranging the drive device and the braking device may be arbitrary as long as the moving force by the drive device and the braking force by the braking device can be applied to the sliding door body. One example is to arrange the drive device and the braking device at the end of the guide member that guides the movement of the sliding door body.

According to this configuration, the guide member and the members, means, and devices arranged around the guide member are configured more than when the drive device and the braking device are arranged above or below the guide member. The vertical dimension of the assembly can be made small, and thus the entire sliding door device can be made compact so as to be compatible with the place where the sliding door device is installed.

When the drive device and the braking device are arranged at the end portions of the guide rails in this way, the end portions of the guide rails on which the drive device and the braking device are arranged are the end portions in the longitudinal direction of the guide rails. However, it may be the upper end portion or the lower end portion of the guide rail.

And an engaging portion 10C.

As shown in FIG. 2, the sliding door body 1 is rotatably attached to the roller brackets 13 and 14.
Individual rollers 15, 16 are arranged in the moving direction of the sliding door body 1, and these rollers 15, 16 arranged above the sliding door body 1 via the roller brackets 13, 14 are as shown in FIG. As an immovable member, it is horizontally installed above the sliding door body 1 and engages with the engaging portion 10C of the guide rail 10. For this reason, the sliding door body 1 includes the rollers 15, 1

Further, as shown in FIG. 1, on the floor 5 close to the door pocket 4, there is arranged a guide roller 17 which is rotatable around a vertical axis. The guide roller 17 is, as shown in FIG. The sliding door body 1 is inserted into the inside of a channel member 1B arranged so as to open downward at the lower end of the sliding door body 1, and the sliding door body 1 moves along the guide rails 10 so that the lower end of the sliding door body 1 moves to the guide roller 17. It is done while being guided.

As shown in FIGS. 2 and 3, a drive device 20 for closing and moving the sliding door body 1 is arranged at the end of the guide rail 10 on the sliding door body closing side, and the sliding door body opening of the guide rail 10 is opened. A braking device 30 for decelerating and braking the speed of the sliding door body 1 when the sliding door is closed is arranged at the end on the side, and these devices 20 and 30 are attached to the guide rails by brackets 21 and 31, respectively. It is attached to 10. The drive device 20 and the braking device 30 have the same structure made of the same member, and each of them has a string-like member 22, 32 and a device body 23, 33.

At least a part of each of the drive device 20 and the braking device 30 arranged separately at both ends in the length direction of the guide rail 10 is within the upper and lower widths of the guide rail 10. At least a part of the driving device 20 and the braking device 30 is disposed at a height position overlapping the vertical width of the guide rail 10.

One end of the first string-like member 22 of the drive unit 20 is connected to the roller bracket 13 on the sliding door body closing side of the two roller brackets 13 and 14 provided in the sliding door body 1, and the other end thereof. The part is inserted inside the device body 23, and one end of the second cord-shaped member 32 of the braking device 30 is coupled to the roller bracket 14 on the opening side of the sliding door body of the roller brackets 13 and 14, and the other end. The part is inserted inside the apparatus main body 33. Each device body 2
3 and 33 are the central axes 24 and 34 and these central axes 2
The casing 23 of the device main body 23, 33 centering around 4, 34
A and 33A are rotatably housed and the other ends of the first cord-shaped member 22 and the second cord-shaped member 32 are joined to wind the first cord-shaped member 22 and the second cord-shaped member 32. It has reels 25 and 35 that can be taken out and paid out, and a spiral spring that applies a rotational force to these reels 25 and 35 that are rotating members.

This will be described with reference to FIG. 5 showing the drive unit 20. A circular recess 25A is formed inside a reel 25 which is rotatable about a central axis 24, and a spiral spring 26 is formed in the circular recess 25A. While being housed, one end 26A of the spiral spring 26 is connected to the reel 25, and the other end 26B is connected to the central shaft 24.

Therefore, when the respective spiral springs are accumulated in the reels 25 and 35 of the drive unit 20 and the braking unit 30, a force in the direction of rotation by these spiral springs is applied. There is. The direction of rotation of the reel 25 by the spiral spring 26 in which the pressure is accumulated in the drive device 20 is
This is the direction in which the sliding door body 1 is moved in the closing direction via the first string-shaped member 22, and the sliding door body 1 holds the grip portion 1 shown in FIG.
When it is opened and moved by A, the reel 25 is rotated by the first cord-like member 22 fed from the apparatus main body 23 to the side opposite to the time when the sliding door main body is closed and moved, so that the spiral spring 26 accumulates pressure. The sliding door body 1 is closed and moved by the accumulated pressure.

Further, when the sliding door body 1 is closed and moved, the spiral spring of the braking device 30 is accumulated with the reel 35 which is rotated by the second cord-shaped member 32 fed from the device body 33. The accumulated spring force of the spiral spring serves as a force to rotate the reel 35 in the direction opposite to the rotation direction of the second cord-shaped member 32, and thus the second cord-shaped member 32 is rotated. The closing movement of the sliding door main body 1 will be braked by being nervous. When the sliding door body 1 opens and moves, the spiral spring of the braking device 30 rotates while releasing the accumulated pressure, and winds up the second cord-shaped member 32.

By setting the spring force of the spiral spring of the drive device 20 for closing and moving the sliding door main body 1 to be larger than the spring force of the spiral spring of the braking device 30 at the time of this closing movement, the sliding door main body 1 is automatically moved. In addition, the closing movement is performed while the braking force by the spiral spring of the braking device 30 is added, and the sliding door main body 1 contacts the vertical frame 3 in FIG. In the vicinity, the accumulated spring force of the spiral spring of the drive device 20 is small, whereas the accumulated spring force of the spiral spring of the braking device 30 is smaller than the spring force of the spiral spring of the drive device, Because it is large, the sliding door body 1
Can be made to reach the closing limit position while gradually decreasing its closing movement speed.

Since the drive device 20 and the braking device 30 have the structures described above, the reel 25 of the drive device 20 and the spiral spring apply a pulling force to the string-like member 22 for closing and moving the sliding door body 1. Tensioning means 27 to generate
And the reel 35 of the braking device 30 and the spiral spring cause the sliding door main body 1 to be closed and moved to the string-shaped member 32.
Pulling means 3 for generating a pulling force for braking
7 are formed.

Further, as shown in FIG. 5 showing the driving device 20, a plurality of corners are continuously formed at equal intervals in the circumferential direction on the central shaft 24 of the driving device 20 and the central shaft 34 of the braking device 30. The square shaft portion 24A is provided. On both sides of this angular shaft portion 24A, both linear portions of an elastic locking member 40 formed by folding back a spring wire into a U-shape are contact locked, and both ends of this elastic locking member 40 are Holding member 41 attached to casing 23A of device body 23
It is fixed at. When the central shaft 24 composed of a bolt is rotated by a tool such as a screwdriver, the angular shaft portion 24A rotates while elastically expanding and deforming both linear portions of the elastic locking member 40, and the spiral spring 26 is rotated in accordance with the rotation direction. The pressure is accumulated or released, and the spring force of the spiral spring changes accordingly. When the rotation operation of the central shaft 24 is stopped, the central shaft 24 is stopped at the rotation angle by the elastic locking action of the elastic locking member 40, and the natural rotation is disabled.

Therefore, the angular shaft portion 24A of the central shaft 24 of the drive device 20 and the elastic locking member 40 form an adjusting means 28 for adjusting the closing movement speed of the sliding door body 1, and the drive device 20 is adjusted. By the angular shaft portion of the central shaft 34 of the braking device 30 and the elastic locking member 42 (see FIGS. 2 and 3), which have the same configuration as the angular shaft portion 24A of the central shaft 24 and the elastic locking member 40, Adjustment means 38 for adjusting the braking force when the sliding door body 1 is closed is formed.

By these adjusting means 28 and 38, the moving speed and the braking speed of the sliding door body can be set to an appropriate size according to the place where the sliding door device is installed, the use of the sliding door device, and the like.

According to this embodiment described above, the drive device 20 for closing and moving the sliding door body 1 and the braking device 30 for applying the braking force to this closing movement are composed of the cord-shaped member 2.
2, 32 and reels 25, 35 of the device main bodies 23, 33,
Since the structure is the same as that of the spiral spring and the like, both the drive device 20 and the braking device 30 can be provided in the sliding door device by the spiral spring type device having these as the constituent members. Since it is not necessary to prepare a plurality of devices having different structures and different structures, it is possible to reduce the types of devices prepared as the drive device 20 and the braking device 30 when manufacturing the sliding door device, and to easily manage them. .

Further, the structure of the sliding door body moving speed adjusting means 28 in the drive device 20 and the braking force adjusting means 38 in the braking device 30 have the same structure, and the operating methods of these adjusting means 28, 38 are the same. Therefore, it becomes easy to learn and implement the work of adjusting these.

Further, since the driving device 20 and the braking device 30 have the same operating principle, the adjusting device 28 of the driving device 20 reduces the spring force of the spiral spring of the driving device 20, and the braking device 30 is smaller than this spring force. If the spring force of the spiral spring is increased by the braking device 30 adjusting means 38, the opening movement of the sliding door body 1 can be automatically moved contrary to the case described above, that is, at this time, the drive device 20 causes the braking device to move. Then, the braking device 30 becomes a driving device, and the driving device and the braking device can be switched and used.

Further, in the present embodiment, as shown in FIGS. 2 and 3, the drive device 20 and the braking device 30 are arranged at the ends of the guide rails 10 for guiding the upper hanging type sliding door body 1. Since these devices are equipped with a guide rail 1
Unlike the case where the guide rail 10 is arranged above or below 0, the vertical size of the guide rail 10 and the assembly including the seamless rail 2 and the like in which the guide rail 10 is housed can be reduced, and therefore, the sliding door can be reduced. The device can be downsized as a whole and can be used for various purposes and various places.

In other words, in the present embodiment, at least a part of each of the drive device 20 and the braking device 30 which are separately arranged at both ends of the guide rail 10 in the longitudinal direction has a vertical width of the guide rail 10. Since it is arranged at a position overlapping with, compared with the case where these devices 20, 30 are arranged above or below the guide rail 10,
The vertical size of the guide rail 10 and the assembly of the seamless rail 2 and the like in which the guide rail 10 is housed is reduced, and therefore the overall size of the sliding door device can be reduced. It can be used for various purposes and in various places.

The same effect as this is obtained by arranging the driving device 20 and the braking device 30 at the upper end portion or the lower end portion of the guide rail 10 instead of at the end portion of the guide rail 10 in the length direction. It is also achieved by disposing at least a part of each of the braking devices 30 at a position overlapping the upper and lower widths of the guide rail 10.

Further, in the present embodiment, the drive device 20 and the braking device 30 are attached to the guide rail 10 by the respective brackets 21 and 31, so that the drive device 20 and the braking device 30 are preliminarily attached to the guide rail 10 at the factory. It can also be attached and transported to the construction site of the sliding door device, and these can be handled at the construction site as a unit body integrated in advance, so that the handling property is improved.

FIG. 6 shows another embodiment of the mounting positions of the driving device 20 and the braking device 30. In this embodiment, the driving device 20 and the braking device 30 are attached to the sliding door body 1, and the end portion of the first string-like member 22 extending from the device body 23 of the driving device 20 is a sliding door of the seamless body 7 which is a stationary member. The braking device 3 is connected to the end portion on the body closing side by a connecting member 43.
The end portion of the second cord-shaped member 32 extending from the apparatus main body 33 of No. 0 is connected to the end portion of the seamless main body 7 on the opening side of the sliding door main body by a connecting member 44.

Also in this embodiment, as in the above-described embodiment, the sliding door body 1 can be braked by the braking device 30 while being automatically moved by the driving device 20, and the sliding door body 1 is slowed down to the movement limit position. Since both the drive device 20 and the braking device 30 are attached to the sliding door body 1, the driving device 20 and the braking device 30 are assembled to the sliding door body 1 in advance at the factory to construct the sliding door device. It can be carried to the site and can be handled as a unit body in which the sliding door body 1, the drive device 20, and the braking device 30 are integrated at the construction site, and the handleability is improved.

Also in this embodiment, at least a part of each of the drive device 20 and the braking device 30 is arranged at a position overlapping the vertical width of the guide rail 10.
Therefore, also in this embodiment, as compared with the case where the drive device 20 and the braking device 30 are arranged above or below the guide rail 10, the guide rail 10 and the seamless eye in which the guide rail 10 is housed are provided. The vertical size of the assembly of 2 and the like can be reduced, and as a result, the overall size of the sliding door device can be reduced, and the sliding door device can be used in various applications and in various places.
