Abstract
The parts forming the force transmission connection from the spindle shaft of the handle of the lock body to the bolt include a spring, which is also arranged to transfer force. The spring is used to eliminate the protrusion of the bolt caused by tolerance variations, when the handle installed into the lock body is turned to its extreme position to open the door.
Claims14
A lock body comprising a body, into which is positioned a bolt, a spindle shaft of the handle, a driver, which is positioned on the spindle shaft of the handle, a follower positioned pivotally on the spindle shaft of the handle and connectable with the driver, and a force transmission linkage to transfer a turning force applied to the spindle shaft of the handle through the follower to the bolt to move it linearly inside the lock body, said parts forming a force transmission connection from the spindle shaft of the handle to the bolt, the force transmission connection comprising freedom of action among its parts, characterized in that the force transmission linkage comprises a biased spring to transfer said turning force to the bolt, through which the turning force applied to the spindle shaft of the handle is arranged to transfer to the bolt, and which spring is arranged to bias further if the bolt is moved inside the lock body and there remains travel distance of the follower towards the pivoted position of the follower, which lock body further comprises a limiter part to limit the linear movement of the bolt inside the lock body without limiting the travel distance of the follower.
