Abstract
A latching device comprising a flanged housing and an associated handle and latch for insertion into an opening in a hinged door in which the handle is pivotally attached to the housing and the latch is pivotally attached to the handle with the handle and the latch having front surfaces which are flat and contiguous with each other and positioned substantially flush with the outer door surface when the handle and the latch are in the latched position in which position the latch engages a keeper on the housing. In the preferred embodiment a spring is affixed to the housing for engagement with the latch when the handle and the latch are moved to the latched position thereby holding the latch in engagement with the keeper.
Claims12
A combination latch and handle device comprising a housing, a handle pivotally attached to said housing, a latch having a button component and a keeper-engagable nose component, said latch being pivotally mounted on said handle and having its button component forming an extension thereof, a keeper on said housing adapted to receive said latch when said handle is moved to its closed position, and a mounting bracket engaging said housing;
- said device further characterized by biasing means mounted on said housing and constructed and arranged to contact and restrain said latch in its latched position;
- said device further comprising a first additional biasing means engaging said housing and said handle whereby the handle and the latch are urged to the open position when the latch is disengaged from the keeper, and a second additional biasing means engaging said handle and said latch whereby the latch is urged to a position in which its handle-extended outer surface is contiguous with the outer surface of said handle.
A combination latch and handle device comprising a housing, a handle pivotally attached to said housing, an arm extending from said handle, a stop on said arm positioned to engage the inner surface of a cabinet when said handle is moved to a closed position, a latch pivotally mounted on said handle and forming an extension thereof, a keeper on said housing adapted to receive said latch when said handle is moved to its closed position, first biasing means engaging said housing and said handle whereby the handle and the latch are urged to the open position when the latch is disengaged from the keeper, second biasing means engaging said handle and said latch whereby the latch is urged to a position in which its handle-extended outer surface is contiguous with the outer surface of said handle, a flange on said housing for engagement with the outer surface of the door when said housing is inserted fully into an opening in the door, and a mounting bracket engaging said housing;
- said device further characterized by a leaf spring mounted on said housing and positioned to contact and restrain said latch in its latched position.
A combination latch and handle device comprising a housing, a handle pivotally attached to said housing, a latch pivotally mounted on said handle and forming an extension thereof, a keeper on said housing adapted to receive said latch when said handle is moved to a closed position, a mounting bracket engaging said housing, and biasing means mounted on said housing and constructed and arranged to contact and restrain said latch in its latched position, said biasing means comprising means for:
- (a) providing relatively high resistance to the initial pivotal movement of said latch out of said latched position,
- (b) providing increased resistance to the further pivotal movement of said latch out of said latched position, and
- (c) providing relatively low resistance to the final pivotal movement of said latch into an unlatched position.
