The present invention relates to the field of locks or connector systems configured to provide a mechanical connection between adjacent components, and particularly to locking systems for securing in a closed position and releasing from the closed position automotive glove box or accessory compartment doors.
Automotive door closure systems, such as glove boxes and the like, typically include a door housing mounted to a dashboard of the vehicle, a door movably mounted to the door housing, and a lockable latch that cooperates with one or more strikers to hold the door in the closed position to cover the door housing. It has been found that there is a continuing need to improve upon or provide alternatives to existing door closure systems in the interests of convenience.
According to a first aspect of the present invention, 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 A motor is configured for moving the plunger between a withdrawn position, in which the plunger is withdrawn within the passageway, and a deployed position, in which the plunger is extended within the passageway relative to the withdrawn position. The plunger is configured to move the pawl out of the passageway upon moving the plunger from the withdrawn position to the deployed position, thereby releasing the door or access panel from the passageway.
According to another aspect of the present invention, a method of using an electronic striker to release a door or access panel from the electronic striker comprises: (i) activating a motor of the electronic striker to move a plunger of the electronic striker from a withdrawn position, in which the plunger is withdrawn within a passageway of the electronic striker, to a deployed position, in which the plunger is extended within the passageway; and (ii) simultaneously moving a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 passageway.
According to still another aspect of the present invention, an electronic striker for releasing a door or access panel includes a housing defining an opening; a plunger that is coupled to the housing and is mounted for movement with respect to the opening; and 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. The plunger is configured to move the pawl upon moving the plunger from the withdrawn position to the deployed position, thereby releasing the door or access panel.
According to yet another aspect of the present invention, a method of using an electronic striker in a manual override mode to release a door or access panel from the electronic striker comprises: (i) manually moving 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; and (ii) simultaneously moving a pawl of the door or access panel during the manual movement 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.
According to yet another aspect of the present invention, a unidirectional worm gear comprises a body and teeth extending outwardly from the body, wherein each tooth has a sloped surface for meshing with a worm and a planar surface opposite the sloped surface.
The above and other aspects and features of the present invention will become more apparent to those of ordinary skill in the art by describing in detail exemplary embodiments thereof with reference to the attached drawings.
Although the invention is illustrated and described herein with reference to specific embodiments, the invention is not intended to be limited to the details shown.

In this embodiment, the electronic striker 20 is an active component that moves in response to a user instruction, whereas the pawl 24a is a passive component that moves in response to movement of the electronic striker 20.
The various active features of the electronic striker 20 will be described hereinafter.
Referring now to
In operation, it should be understood that rotation of output shaft 34 causes rotation of worm 36, which causes rotation of worm gear 38, which causes rotation of transfer gear 42, which causes rotation of cam lifter gear 44. The gears 36, 38, 42 and 44 may be referred to herein as a gear arrangement.
Referring now to
Referring now to
The cam surface 48 is a single continuous surface that rises and falls in a direction that is parallel to an axis of rotation of the gear 44. The cam surface 48 includes a gently sloping surface 48a which is followed by and joined to a rapidly sloping surface portion 48b , as viewed in a circumferential direction and along the axis of rotation. The gently sloping surface 48a slopes in an upward direction toward the top end of the gear 44, whereas the rapidly sloping surface portion 48b slopes in a downward direction toward the bottom end of the gear 44 (i.e., toward teeth 46), as viewed in a circumferential direction. The absolute value of the slope of portion 48b is greater than that of the portion 48a . The gently sloping surface 48a constitutes about 75% (or more) of the circumference of the gear 44, whereas the rapidly sloping surface portion 48b constitutes about 25% (or less) of the circumference of the gear 44. Stated differently, rapidly sloping surface portion 48b constitutes about 90 degrees of the circumference of the cam surface 48, and the portion 48a constitutes about 270 degrees. As will be described later, the cam surface 48 of the gear 44 interacts with a pin 54 extending from the plunger 26 for translating the spring-loaded plunger 26 in an outward direction that is parallel to the axis of rotation of the gear 44.
The protrusion 50 of the gear 44 is an indexed surface comprising a ramp having a curved entrance surface 50a , a flat travel surface and a curved exit surface, as viewed in a circumferential direction. As will be described later, the protrusion 50 interacts with a wiper 57 (
The protrusion 50 may be referred to herein as an indexing means. As an alternative to the protrusion, those skilled in the art will recognize that the indexing means could be a surface, recess, marking, magnet, circuit, magnetic feature, optical feature, post, slot, or pin, for example, or any other feature on the gear 44 that can be used for tracking movement of the gear 44. Also, the indexing means could be provided on a different gear of the gear arrangement.
Referring now to
A pin 54 extends perpendicularly from another one of the elongated sidewalls of the plunger 26. The pin 54 is positioned to extend over the cam surface 48 of the gear 44. Rotation of the cam surface 48 causes translation of the pin 54 and its plunger 26, as will be described in greater detail later. For that reason, the cam surface 48 may be referred to herein as a cam, and the pin 54 may also be referred to herein as a cam follower.
A compression spring 62 is positioned within the slot 64 along with the peg 60. The spring 62 is either mounted to or bears on a protrusion 63 on a lower surface of the peg 60. Specifically, one end of the spring 62 bears on the protrusion 63, and the opposing end of the spring 62 bears on a similar peg or other surface defined on the base 30, thereby captivating the spring 62 within the slot 64. The spring 62 is biased to move the peg 60 (and, therefore, the plunger 26) toward the withdrawn state shown in
The electronic switch 56 is configured to detect rotation of the gear 44, and communicate one or more rotational positions of the gear 44 to a processor and/or controller of the striker 20. The switch 56, processor and/or controller may be disposed on a circuit board 70 as shown in
Referring now to an exemplary method of operating the striker 20,
