It is characterized in that the termination.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 1 to 5.

Reference numeral 1 denotes a main bracket fixedly coupled to the upper wall surface of the doorway, and a cross section of the main bracket 1 is formed in a 'L' shape as a whole, and a rail 2 for guiding the rolling movement of the roller below the main bracket 1. It is formed long.

Reference numeral 6 denotes a door that opens and closes the entrance and exit, and a first roller 3 and a second roller 4 are formed at the front and rear portions of the upper surface of the door 6, respectively. 3 and 4 are coupled to the upper surface of the door 6 in a state supported by the separate roller bracket (3a, 4a), the roller (3, 4) is coupled to the rail (2) rail (2) The door 6 is opened and closed while sliding from above.

The height of the rollers 3 and 4 installed on the upper surface of the door 6 may be adjusted between the roller brackets 3a and 4a and the door 6 by interposing a height adjusting plate 60 having a predetermined thickness.

And, the inner surface of the first roller bracket (3a) in which the first roller 3 is axially protruding the locking projection (5) for catching the wire 17 of the pulling force applying means 10 to be installed later The locking roller 53 is coupled to one side of the second roller bracket 4a as a bolt, and a groove 7 is formed on the lower side of the door 6 and the groove 7 is formed on the bottom of the doorway. The guide roller 8 protrudes so that it may be located in ().

Accordingly, the door 6 is opened and closed by slidingly driving the first and second rollers 3 and 4 seated on the rails 2 and the grooves 6 guided downward to the guide rollers 8. Preferably, the installation position of the guide roller 8 is located at the rear end of the door 6 when the door 6 is closed, as shown in FIG.

A stopper 50 is formed at an end of the main bracket 1 (a position at which the door is fully opened) to limit the opening range when the door 6 is slid open. The stopper 50 is formed above the stopper 50. The catching roller 53 is bent and the catching ring 51 which hold | maintains so that the door 6 may be kept open is bent.

On the other hand, in the present invention, the pulling force applying means 10 for providing a pulling force so that the door 6 is automatically closed and the buffer means 20 for buffering the opening and closing operation of the door 6 to proceed slowly.

The pulling force applying means 10 couples the housing 11 to the tip end of the main bracket 1 as a bolt, and winds the spring 13 and the wire 17 inside the housing 11.

A circular bobbin 12 is rotatably installed in the housing 11, but the fitting groove 16 for pressing the end portion of the spring 13 in the inner center of the bobbin 12 is circumferentially connected. The center body 14 formed in the axial, and inserted into the control rod 15 eccentrically inside the center body 14, one end of the control rod 15 is exposed to the outside of the housing 11 of the user By operation, the adjusting rod 15 was rotated forward and backward.

When the user rotates the adjusting rod 15 in the A direction, the spring 13 is wound around the central body 14, thereby increasing the elasticity accumulated in the spring 13, and rotating the adjusting rod 15 in the B direction. When the spring 13 is released from the central body 14, the elasticity accumulated in the spring 13 is reduced, and the overall opening and closing speed of the door 6 is adjusted according to the manipulation of the adjusting rod 15 of the user.

In addition, the coil-shaped spring 13 is wound on the inner circumferential surface of the bobbin 12, the end of the spring 13 is bent and forcibly fitted into the fitting groove 16 of the central body 14 to hold the spring 13. ) So that the elasticity of the wire can be transmitted to the bobbin 12, the wire 17 having a predetermined length is wound on the outer circumferential surface of the bobbin 12, and the end of the wire 17 is connected to the first roller 3. When the door 6 is opened by the locking protrusion 5, the bobbin 12 is rotated counterclockwise as the wire 17 is pulled out, whereby the spring 13 wound around the bobbin 12 is wound. The elasticity is accumulated while being wound on the central body 14, and when the opening operation of the door 6 is stopped, the bobbin 12 is rotated by the restoring force of the spring 13 and the wire 17 is pulled as the door 17 is rotated. (6) will be automatically closed.

On the other hand, the shock absorbing means 20 is to buffer the opening and closing speed of the door 6 to proceed slowly, a plurality of fixing brackets 21 is installed in the central portion of the main bracket (1), the fixing bracket 21 A cylinder 22 having a piston 23 to be mounted on and mounted on the cylinder 22, and the end of the piston 23 can be inserted into one side of the second roller bracket 4a to which the second roller 4 is coupled. Coupling portion (40) having an insertion portion (42) formed in the shape of a funnel, the magnetic body (24, 41) formed on the end of the piston 23 and the inside of the insertion portion 42, respectively, the piston (23) ) Is coupled to the insert 42.

By implementing the coupling of the piston 23 and the insertion portion 42 as the magnetic material (24, 41), it is possible to easily implement the coupling between the piston 23 and the connecting portion (40).

That is, the magnetic body 24 of the piston 23 and the magnetic body 41 of the insertion part 42 by removing the piston 23 from the cylinder 22 and bringing it close to the insertion part 42 as shown in FIG. 4. The piston 23 and the insertion portion 42 are firmly coupled to each other by the pulling force of, and when removed, the piston 23 can be easily removed by pulling the piston 23 with a constant force.

The shock absorbing means 20 compresses or sucks air in the cylinder 22 while the piston 23 moves forward and backward with the door 6 to open and close the door 6 to cushion the opening and closing speed of the door 6. In the present invention, a separate buffer pressure adjusting unit 25 for adjusting the degree of buffering is formed on one side of the cylinder 22 (the direction opposite to the piston).

The buffer pressure adjusting unit 25 adjusts the degree of cushioning by adjusting the flow amount of air supplied into or out of the cylinder 22 when the piston 23 is in and out of the cylinder 23, and the case 26 on one side of the cylinder 22. And a plurality of pneumatic flow passages 27 and 28 communicating with the inside of the cylinder 22 in the case 26, and in each of the pneumatic flow passages 27 and 28, a ball valve ( 29) are provided to control the pneumatic flow passages 27 and 28.

In addition, when the user inserts the adjustment bolt 30 deeply by inserting the adjustment bolt 30 for controlling the opening amount of any one of the air pressure flow passage (27,28) from the outside of the case 26. Since one pneumatic flow passage is blocked, the amount of air supplied to or discharged from the cylinder 22 as a whole is reduced, so that the opening and closing operation of the piston 23 proceeds more slowly, thereby reducing the opening and closing speed of the door 6. When the depth of insertion of the adjustment bolt 30 is reduced, the blocked air pressure flow passage is opened, and the amount of air supplied to or discharged from the cylinder 22 is increased, thereby making the piston 23 appear more quickly. The opening and closing speed of the door 6 is to be increased.

According to the non-powered automatic sliding door of the present invention configured as described above, the door 6 is slid and opened by the rollers 3 and 4 rolling on the rails 2, so that the user can easily open the door 6 without applying great force. After passing through the doorway, the door 6 is automatically closed by the restoring force (elasticity) provided by the spring 13 of the pulling force applying means 10, thereby providing convenience in use. Opening and closing speed of the door 6 is buffered by the buffer means 20 to be made slowly, so the door opening and closing noise is significantly reduced.

In addition, since a separate rail does not need to be provided on the bottom surface of the doorway, a physically handicapped person, especially a handicapped person using a wheelchair, can conveniently open the door 6 to pass through the doorway in a public office or a hospital. It can be very useful.

As described above, the present invention installs the main bracket provided with the rail on the upper side of the entrance, and combines the door to the lower side of the plurality of rollers sliding on the rail to allow the door to slide open and close, the open door is automatically closed The opening force of the door is made natural by forming a pulling means applying means to apply elastic force to one end of the main bracket, and forming a separate buffer means at the center of the main bracket to cushion the opening and closing of the door gradually. Of course, the opened door is automatically closed by the elastic force of the pulling force applying means, and since the rail is not formed at the bottom of the door, the jaw is not formed at the bottom of the doorway, so that the physically disabled people have a great force. A non-powered automatic pusher that opens and slides through the sliding door without lifting You can expect an effect to provide it.
