Abstract

PURPOSE: To provide a door closer for slide door, in which a cylinder is arranged in the top stile of slide door or a vertical door frame, and a shut-off valve of a weight is communicated with the upper and lower chambers of said cylinder, whereby outer appearance of the slide door can be improved and the door can be opened or closed at an appropriate speed.
CONSTITUTION: Cylinder 1 is arranged in the top stile of slide door 3 or vertical stile 23 of frame 22, and a vertically movable weight 9 is fitted in the cylinder 1. The weight 9 is provided with a shut-off valve 19, which is opened by the pressure difference between upper chamber 1A and lower chamber 1B of the cylinder 1 caused with upward movement of the valve 19. A passage 18 is provided between the two chambers 1A and 1B for communicating them with each other, whereby, if valve 19 is closed with downward movement of weight 9, it is allowed to move downward at an appropriate speed. Further, rope 20 connected at one end thereof to the weight 9 is wound around guide roller 7 and connected at the other end to the vertical stile 23. With such an arrangement, outer appearance of the door can be improved since cylinder 1 is incroporated in the stile, and door 3 can be opened and closed, both manually and automatically, at an appropriate speed by the function of shut-off valve 19.
