Abstract
An electronic striker for releasing a door or access panel includes a housing defining an opening and a passageway extending from the opening for receiving a pawl on the door or access panel. A plunger is coupled to the housing and is mounted for movement within the passageway. A motor is configured for moving the plunger between a withdrawn position, in which the plunger is withdrawn within the passageway, and a deployed position, in which the plunger is extended within the passageway relative to the withdrawn position. The plunger is configured to move the pawl out of the passageway upon moving the plunger from the withdrawn position to the deployed position, thereby releasing the door or access panel from the passageway.
Claims23
An electronic striker for releasing a door or access panel, the electronic striker comprising:
- a housing defining an opening;
- a plunger that is coupled to the housing and is mounted for movement with respect to the opening;
- a motor configured for moving the plunger between a withdrawn position, and a deployed position, in which the plunger is extended relative to the withdrawn position;
- a gear arrangement that is configured to convert rotation of an output shaft of the motor to linear translation of the plunger between the withdrawn and deployed positions, wherein the gear arrangement comprises a cam lifter gear having a cam surface, and the plunger comprises a cam follower that engages with the cam surface, wherein rotation of the cam surface causes translational movement of the cam follower, wherein the cam follower is a pin that is fixed to the plunger;
- wherein the cam surface is a continuous surface that rises and falls in a direction that is parallel to an axis of rotation of the cam lifter gear, wherein the cam surface comprises a first sloping surface that slopes up in an upward direction toward of a top end of the cam lifter gear which is followed by and joined to a second sloping surface that slopes in a downward direction toward a bottom end which is opposite the top end of the cam lifter gear, as viewed in a circumferential direction and along the axis of rotation;
- and
- wherein the plunger is configured to move the pawl when the plunger is moved from the withdrawn position to the deployed position, thereby releasing the door or access panel.
A method of using an electronic striker to release a door or access panel from a housing for the door or access panel, the housing defining an opening, the method comprising:
- activating a motor of the electronic striker to move a plunger of the electronic striker from a withdrawn position, in which the plunger is withdrawn within a passageway, to a deployed position, in which the plunger is extended within the passageway, the plunger being coupled to the housing and is mounted for movement with respect to the opening;
- simultaneously moving a pawl of the door or access panel during the activating step from a position in which the pawl is positioned within the passageway to a position in which the pawl is positioned either outside or substantially outside of the passageway, thereby releasing the door or access panel from the housing for the door or access panel;
- wherein, upon activating the motor, an output shaft of the motor rotates a gear, and rotation of the gear causes linear translation of the plunger between the withdrawn and deployed positions;
- wherein the gear is a cam lifter gear having a cam surface, and the plunger comprises a cam follower that engages with the cam surface, wherein rotation of the cam surface of the gear causes translational movement of the cam follower, wherein the cam follower is a pin that is fixed to the plunger;
- and
- wherein the cam surface is a continuous surface that rises and falls in a direction that is parallel to an axis of rotation of the cam lifter gear, the cam surface comprising a first sloping surface that slopes up in an upward direction toward of a top end of the cam lifter gear which is followed by and joined to a second sloping surface that slopes in a downward direction toward a bottom end which is opposite the top end of the cam lifter gear, as viewed in a circumferential direction and along the axis of rotation.
