Abstract: A mechanical push button lock used to control locked/unlocked state of a specific element of a machine, such that when the mechanical push button lock is locked then the specific element also is locked. The proposed mechanical push button lock includes a push key, an actuating rod, a cross rod, a shaft and a spring. The push key is located in one end of the actuating rod, the actuating rod couples with the cross rod in another end of the actuating rod and the spring connects the actuating rod and the cross rod. Moreover, when the mechanical push button lock is locked then the cross rod contacts the specific element such that the specific element also is locked. Therefore, when the push key is pressed then the actuating rod slides until it contacts the cross rod. Afterwards, the cross rod is pushed by the actuating rod and rotates around the shaft. When the rotating angle is large enough then the cross rod does not contact the specific element and the specific element is unlocked.

Abstract: An automatic protection device for a roller blind to prevent unauthorized raising of the blind from the outside by means of two-arm toggle joints whose lever ends are linked at one of the adjacent roller blind staves so that upon unauthorized raising the free toggle joint moves against the flange of U-shaped guide channel in combination with a compensating member in the face region of the upper roller blind stave and movable relative thereto exerts on the locking teeth of the free toggle joint through the action of an additional force means such as an elastic compressible material, a pressure by which the locking teeth are brought against the flange of the guide channel. This not only assures positive locking but also acts to compensate for differences in stave spacings and widths of guide channels thereby reducing manufacturing and inventory costs.

Abstract: There is disclosed a latchbolt assembly which replaces conventional rectilinear latchbolt movement with dual direction swinging movement to reduce binding forces and which uses two independently operable dead latches in association with the dual swinging motions of the latchbolt. To facilitate release, as by key or panic bar actuation, the load of the latchbolt mass and friction is substantially eliminated by coupling the release system to one of the dead latches and thereafter utilizing camming action derived from the opening of the door to swing the latchbolt out of its keeper. Thus hard pressure against the door will not hamper the release. The second dead latch is operated by a latch feeler finger which frees the latchbolt only when the door is open thereby to facilitate relatching by swinging into the keeper as the door closes.
