Self-locking push button

A pushbutton for unlocking a lock of a door, a hood, a covering or a hatch, comprising

• a) a pushbutton housing,
• b) an actuation knob seated in the pushbutton housing comprising an actuation knob housing, and having a non-actuated position and an actuated position,
• c) a latch for locking the actuation knob in the non-actuated position, wherein the actuation knob in an unlocked state can be displaced linearly along an actuation axis in a pushbutton actuation direction from the non-actuated position into the actuated position relative to the pushbutton housing,
• d) a cylinder lock with a cylinder lock core seated in the actuation knob housing and a corresponding key,
• e) wherein the actuating knob can only be unlocked when the corresponding key is introduced into the cylinder lock core,
• f) wherein the pushbutton is designed such that the actuation knob returns back from the actuated position into the non-actuated position in a self-actuated manner and is locked in a self-actuated manner,
• wherein the key introduced into the cylinder lock core can only be withdrawn in the non-actuated and a locked position of the pushbutton,
• wherein the actuation knob comprises the actuation knob housing, a sleeve and two connecting webs which connect the sleeve to the actuating knob housing,
• wherein the connecting webs each comprise a first, radially outward protruding guide strip extending in the axial direction, wherein the first guide strips each extend up to and along the sleeve and protrude radially outward from a sleeve wall of the sleeve.

• a) a pushbutton housing,
• b) an actuation knob seated in the pushbutton housing comprising an actuation knob housing, and having a non-actuated position and an actuated position,
• c) a latch for locking the actuation knob in the non-actuated position, wherein the actuation knob in an unlocked state can be displaced linearly along an actuation axis in a pushbutton actuation direction from the non-actuated position into the actuated position relative to the pushbutton housing,
• d) a cylinder lock with a cylinder lock core seated in the actuation knob housing and a corresponding key,
• e) wherein the actuating knob can only be unlocked when the corresponding key is introduced into the cylinder lock core,
• f) wherein the pushbutton is designed such that the actuation knob returns back from the actuated position into the non-actuated position in a self-actuated manner and is locked in a self-actuated manner, wherein
• the key introduced into the cylinder lock core can only be withdrawn in the non-actuated and a locked position of the pushbutton,
• wherein the pushbutton comprises the latch for locking of the actuating knob, by means of which the movement of the actuating knob can be locked in the pushbutton actuation direction,
• wherein the cylinder lock core is non-rotatably connected to the latch about the actuation axis,
• wherein the latch comprises an actuation segment receiving groove in which an actuation segment of the cylinder lock core is arranged in a positive-locking manner such that the cylinder lock core is connected to the latch non-rotatably about the actuation axis.

• e) wherein the actuating knob can only be unlocked when the corresponding key is introduced into the cylinder lock core,
• f) wherein the pushbutton is designed such that the actuation knob returns back from the actuated position into the non-actuated position in a self-actuated manner and is locked in a self-actuated manner,
• wherein the key introduced into the cylinder lock core can only be withdrawn in the non-actuated and a locked position of the pushbutton,
• wherein the key cannot be withdrawn either during an actuation stroke or during a return stroke, in that the cylinder lock core cannot be rotated relative to the actuation knob during the actuation stroke and during the return stroke.
