Abstract
A locking mechanism is provided that has an unlocked position and a locked position. The locking mechanism comprises the following. A first handle. A first rose attached to the first handle with the first handle adapted for rotational movement relative to the first rose. A first longitudinal slot in the first rose. A locking cartridge cylinder at least partially contained within at least the first handle or the first rose. A locking tab operably connected to the locking cartridge cylinder adapted for movement: at least partially into at least the second slot in the first rose in a locked position; and completely out of the first longitudinal slot in the first rose in an unlocked position.
Claims15
In a locking mechanism having an unlocked position and a locked position, the locking mechanism comprising:
- a) a first handle;
- b) a first rose attached to the first handle with the first handle adapted for rotational movement relative to the first rose:
- c) a first longitudinal slot in the first rose extending through a width of the first rose, and parallel to a longitudinal axis defined by the locking mechanism;
- d) a locking cartridge cylinder at least partially contained within at least the first handle or the first rose;
- and
- a locking tab operably connected to the locking cartridge cylinder adapted for movement that is at least partially perpendicular to the longitudinal axis:
- (1) at least partially into at least the first longitudinal slot in the first rose in a locked position;
- and (2) completely out of the first longitudinal slot in the first rose in an unlocked position, and a second longitudinal slot in the first handle, wherein the first longitudinal slot in the first rose is alignable with the second longitudinal slot in the first handle.
A hub core assembly for use in a locking mechanism between a first handle assembly and a second handle assembly, the hub core assembly comprising:
- a first housing connected to an opposing second housing;
- a) the first housing including:
- a protruding first portion having a notch with a first through hole;
- and
- a protruding second portion;
- b) the second housing including:
- a protruding first portion having a notch with a second through hole;
- and
- a protruding second portion;
- and
- the first housing protruding second portion seats within the second housing notch and the second housing protruding second portion seats within the first housing notch.
In a locking mechanism having an unlocked position and a locked position, first and second handles each adapted for rotational movement;
- a hub core assembly operably connected to the first and second handles, a first rose adjacent the first handle and connected to one end of the hub core assembly, the hub core assembly operably connected to a latch assembly having a latch seatable, and removable, from an adjacent jamb opening in the unlocked position and not removable from the adjacent jamb opening in the locked position;
- the improvement comprising locking means for
- (a) preventing removal of the latch from an adjacent jamb opening in the locked position, and
- (b) permitting removal of the latch from an adjacent jamb opening in the unlocked position,
- the locking means including
- (i) a locking cartridge at least partially contained within at least the first handle or the first rose, and
- (ii) a locking tab (I) seatable within the first rose for maintaining the seated latch within the adjacent jamb opening in the locked position, (II) operably connected to the locking cartridge and adapted for movement from a first position in the unlocked position to a second position in the locked position, and (III) biased in the unlocked position by a lock pin spring proximate a lock pin by which the locking tab is operably connected to the locking cartridge.
