DOOR LOCK OR HINGED LID Russian patent published in 2018 - IPC E05B65/00 

FIELD: machine building.

SUBSTANCE: object of the present invention is to provide a lock for a door or hinged lid that would allow for easy opening, reliably and with little effort. To solve this problem, the lock for the door or hinged lid is manufactured with a locking mechanism from the pivoting latch and, at least, one pawl to fix the rotatable latch. In addition, the lock includes a release lever, with the help of which you can unlock the locked locking mechanism by acting on the release lever. Lock includes a spring for moving the pawl in the direction of the fixed position. Release lever is designed in such way, when exposed to it, at least a decrease occurs, and preferably, elimination of the force of the spring acting on the pawl. Thus, effect on the release lever at least reduces the tension of the spring, that presses on the pawl in the direction of the fixed position. Since this force prevents unlocking of the locking mechanism, the effect on the release lever at least reduces or even completely eliminates such obstruction, when the force of the spring is fully retracted. Since the release lever has a dual function, the number of necessary parts is kept at a low level.

EFFECT: it give the possibility to produce at low flow rates, a small installation space and with low weight.
