Abstract
Description
The present invention relates to a sliding door semi-automatic door piston used in a sliding door and a sliding door semi-automatic door using the same.
Generally, a sliding door is provided with a door frame on a wall of a building, and a rail is laid on the door frame so that the door is opened or closed while the user slides by pushing or pulling.
Such sliding doors are automatically opened and closed for the convenience of customers and users when they are installed at the main entrance of a building with frequent entrance and exit.
Korean Patent Registration No. 10-0232774 discloses a
When a sliding door is opened in Japanese Laid-Open Patent Publication No. 2001-12138 (2001, 1, 16), a spring force is accumulated in a return spring, and the sliding door is closed by the force of the accumulated spring. At the same time, A door closure for providing resistance is described,
In Korean Patent Laid-Open Publication No. 1989-9740, a spring (4) and a wire (5) are connected between a door (1) and a housing (2) fixed to a door frame so that the door automatically closes And a damper 8 is provided between the housing and the door so as to be quietly closed at the end of the door closing state. Here, the damper includes a cylinder 10 including an intake hole 13 provided with a one-
In Korean Utility Model Publication No. 1989-0000740 (Aug. 25, 1985), an automatic closing device is provided on the upper side of a door attaching portion which is configured to open and close a passageway by a sliding door. In the automatic closing device, Stage pipe 9 and the three-
The conventional techniques described above solve the problem that the wires are installed on both sides of the hanger outside on both sides of the hanger to increase the volume of the device and make the installation difficult because of its heavy weight and frequent occurrence of breakdown and breakage during use over a long period of time. It is a task.
In order to solve the above-mentioned problems, the present invention provides a method of detecting a defect in a semiconductor device, which is disclosed in Korean Patent Application No. 10-2010-1770 (Registration No. 10-1137414), No. 10-2009-77419 (Registration No. 10- 10-1117655, No. 10-1117655, No. 10-1117655), a door automatic closing device and an automatic closing device of a sliding door, which are provided with a piston accumulating
A piston back
The present invention is advantageous in that a door manually opened by a passenger is closed automatically without depending on a separate power source, thereby reducing waste of energy and making the apparatus compact, which is easy to install and low in installation cost, It is possible to perform a closing operation of the door quickly and quietly by the action of the air control valve, the spring and the wire in the air cylinder, so that the failure and the breakage rate are small.

In order to achieve the above-mentioned object, the present invention provides a piston for a vehicle, comprising: a piston
In the piston of the present invention, a piston moving
When the
On the other hand, when the piston
The hanger of the present invention is a frame hanging a door,
The air cylinder of the present invention is provided with an air control valve at an end thereof,
In the operation of the air cylinder, when the door is opened by hand (Fig. 2), the moon bed installed on the door moves backward, the piston is advanced by the wire connected to the moon bar (Fig. 5), the spring connected to the rear surface of the piston shaft is inflated, Air is allowed to pass through the air cylinder,
On the contrary, when the hand is released from the door (FIG. 8), the piston is moved backward (FIG. 10) by the compression force of the spring (FIG. 10), and the air existing in front of the piston flows into the air cylinder So that the air pressure inside and outside of the air cylinder is made the same, and the door is closed slowly and smoothly.
When the door is opened, the piston (Fig. 5) is advanced by the force of hand-pushing (Fig. 2). At this time, air in the front surface of the piston passes between the center of the piston shaft and the piston moving
When the door is closed (Fig. 8), the piston is retracted by the force of the expansion spring being contracted (Fig. 10), the pressure in the air on the front surface of the piston of the air cylinder is lowered, And the pressure inside the air cylinder is equal to the pressure of the outside and the rear surface of the piston to smoothly close the door to adjust the closing speed.
Hangs the door, hanging the door, and locks the door in the door hanger Laura.
Hereinafter, the present invention will be described in detail with reference to the drawings.
