Safety braking device for doors
First Claim
1. A safety braking device for doors, arranged between a door board and a permanent seat, the door board having an unlocked (opened) position and a locked (closed) position with respect the permanent seat, comprising:
- a seat body, arranged in the door board;
wherein, when the door board is shifting from the locked position to the unlocked position, the seat body moves along a first direction of the permanent seat;
wherein, when the door board is shifting from the unlocked position to the locked position, the seat body moves along a second direction of the permanent seat;
a one-way locking mechanism, including a lock position element and a connecting rod element, the lock position element being able to displace toward and lock at the connecting rod element at the first direction, the lock position element being arranged in and co-moved with the seat body, one end of the connecting rod element being fixed onto the permanent seat while another end thereof being extended into the seat body by corresponding to the lock position element, the lock position element being switched between an engaged position and a disengaged position;
wherein, when the lock position element is at the engaged position, the lock position element as well as the seat body are fixed in the first direction with respect to the connecting rod element so as not to open the door board, but the lock position element associated with the seat body is displaceable in the second direction with respect to the connecting rod element so as to close the door board;
wherein, when the lock position element is at the disengaged position, the door board is eligible to be opened and to be closed;
a switching mechanism connected between the lock position element and a handler furnished on the door board;
wherein, when the handler is operated, the switching mechanism switches the lock position element from the engaged position to the disengaged position;
a spring element, engaged with the lock position element so as to restrain elastically the lock position element at the engaged position while in normal situations; and
a positioning pair, including an elastic positioning member and a corresponding positioning block, wherein the elastic positioning member is arranged at the seat body while the corresponding positioning block is arranged at the lock position element;
wherein a first end portion of the connecting rod element is pivotally connected to the permanent seat, an external force is introduced by operating the handler to drive and switch the lock position element to the disengaged position so as simultaneously to open the door board by an angle less than a first angle θ
1, and the corresponding positioning block is fixed to the elastic positioning member so as to sustain the lock position element at the disengaged position;
wherein, when the door board is pushed away from the permanent seat to an angle larger than the first angle θ
1, a position-resuming element connecting with the second end portion of the connecting rod element pushes and displaces the corresponding positioning block of the positioning pair away to separate the elastic positioning member, and the spring element resumes elastically the lock position element to the engaged position;
that is, the door board is able to be locked to the permanent seat one-directionally after the door board is released from an angle larger than the first angle θ

Abstract
A safety braking device (1) for doors, which is arranged between a door board (21) and a permanent seat (22) of the door board, comprises a seat body (11) and a one-way locking mechanism. The seat body (11) is arranged in the door board (21). The one-way locking mechanism comprises a lock position element (12) and a connecting rod element (13). The lock position element (12) is arranged in the seat body (11) and can be switched between a locked position and an unlocked position. One end of the connecting rod element (13) is fixed onto the permanent seat (22) of the door board, and the other end thereof extends into the seat body (11) and corresponds to the lock position element (12). When at the locked position, the lock position element (12) as well as the seat body (11) cannot move in a first direction (91) with respect to the connecting rod element (13), and thereof the door board (21) cannot be opened and can only be closed; and only when the lock position element (12) is at the unlocked position can the door board (21) be opened or closed.
