Door closing sequence controller

Abstract

A door closing sequence controller (10) utilized to control closing sequence between a leading panel (F) having a first door closer (C1) and a trailing panel (M) having a second door closer (C2), comprises a first actuator mechanism (11), a second actuator mechanism (12), a fixing base (13) disposed between the first actuator mechanism (11) and the second actuator mechanism (12), a movable base (14) disposed at the fixing base (13), a locking mechanism (15) disposed in the movable base (14), and a blocking pin (16), the movable base (14) comprises an accommodating space (145), the blocking pin (16) is disposed in the accommodating space (145), the locking mechanism (15) remains clamping the second actuator mechanism (12) till the first actuator mechanism (11) interacts with the locking mechanism (15), such that the locking mechanism (15) can release the second actuator mechanism (12) from clamping.

Description

technical field [0001] The invention relates to a door-closing sequence controller, in particular to a door-closing sequence controller which uses a locking mechanism to achieve door-closing sequence control. Background technique [0002] Due to the different structures and functions of the existing known movable doors and passing doors, they must be closed in sequence when closing. The movable door must be closed first, and then the passing door must be closed. In order for the user to close the movable door in sequence door and passage door, so the door sequence controller assists the user to correctly close the movable door and the passage door, such as the "door closing sequence controller for double doors" disclosed in German Patent DE10111732, such as figure 1 As shown, it is to make a door-closing sliding rod R connected to the passage door pass through a circular splint O, and control the mobility and door closing sequence of the closing sliding rod R by adjusting th...

Problems solved by technology

[0002] Due to the different structures and functions of the existing known movable doors and passing doors, they must be closed in sequence when closing. The movable door must be closed first, and then the passing door must be closed. In order for the user to close the movable door in sequence door and passage door, so the door sequence controller assists the user to correctly close the movable door and the passage door, such as the "door closing sequence controller for double doors" disclosed in German Patent DE10111732, such as figure 1 As shown, it is to make a door-closing sliding rod R connected to the passage door pass through a circular splint O, and control the mobility and door closing sequence of the closing sliding rod R by adjusting the swing angle of the circular splint O. When the movable door When both the door and the passage door are opened, the swing angle of the circular splint O is greater than 0 degrees (dashed line), and the circular splint O will block the door-closing slide bar R, so that the door-closing slide bar R cannot move, and then the door-closing slide bar R can be locked. The restricted access door is closed first; otherwise, when the movable door is closed first, the swing angle of the circular splint O will be adjusted to 0 degrees (the solid line part) to release the door-closing slide bar R, because the door-closing slide bar R It can move freely, and the pass-through door can be closed smoothly. However, the structure of the known circular splint O is relatively thin, and the contact area between it and the sliding rod R for closing the door is small, which is likely to cause stress concentration. The splint O is prone to deformation and loses its function, resulting in the failure of the door closing sequence control function
