FIELD: construction; applicable for locking, mainly, of doors of amenity rooms. SUBSTANCE: door bolt with handle-button has laid-on body and locking strip of box shape, both, provided with means for their installation on the door of locked object, and handle having through stepped hole for fastening to the body by means of hollow bushing with shoulder in the handle, and nut from the inside of the body. Installed inside the body is bolt longitudinal motion and interaction with locking strip during locking. Bolt is spring-loaded relative to the body front wall with spring thrusting the split washer which is installed in the recess made on bolt. U-shaped guides are made on the inner sides of the lower and upper walls of the body parallel to bushing axis. Bushing accommodates a rod on which spring is located which thrusts the bushing shoulder and nut installed on the rod end. The nut forms together with union cap a push button located in handle holes. Rod other end is connected with retainer installed in U-shaped guides for motion in the plane square to bolt motion. Retainer has hole accommodating bolt for longitudinal motion in it. Bolt has recess whose width exceeds retainer thickness for fixing bolt in locked position by displacement of retainer hole under the action of spring on the rod. Bolt when unlocking is pressed-out after pressing the button by means of moving the washer up to stop against U-shaped guides from their outside. Bolt one end has pushing key located in the body rear wall, with the help of which, spring-loaded bolt, with its other end, is manually moved into locking strip up to alignment of the retainer with recess on the bolt. EFFECT: higher efficiency. |
