  • Patent number: 12553258
    Abstract: A latch assembly includes a bolt selectively moveable between an extended position and a retracted position. A cam blocker is included and positionable in different configurations. In one configuration, the cam blocker allows the bolt to move towards the retracted position with actuation of a handle in two different rotational directions. In another configuration, the cam blocker allows the bolt to move towards the retracted position with actuation of the handle in only one rotational direction. The latch assembly is also adjustable between at least two different backset distances.
    Type: Grant

  • Patent number: 12234666
    Abstract: An adapter for either a handle set or a lever set door lever is equipped with a pair of springs to provide a pre-load on the spindle. The pre-load prevents sagging of the lever due to the large mass of the lever. A sleeve in the adapter is formed out of a compressible material that accepts the spindle in a press-fit configuration. This allows for greater manufacturing tolerances while still providing a solid and secure engagement between the spindle and the adapter. As a result, any free play in the lever is eliminated and the lever is maintained in a horizontal, home position when the lever is not in use. Following use through rotation of the lever, the springs promptly return the lever back to the home position while the sleeve prevents any slop or free-play in the lever's motion.

  • Patent number: 11505973
    Abstract: A spring assembly for a handle set assembly includes a housing and a gear rotatably positioned within the housing. The gear has a default position and at least one actuated rotated position. The spring assembly includes at least one rack positioned within the housing. The at least one rack is movable in a rack displacement direction that is normal to the axis of rotation of the gear in response to rotation of the gear between a neutral position and a displaced position. The spring assembly includes a slider positioned at a first end of the at least one rack, the slider being slidable along the rack displacement direction. The spring assembly includes at least one spring captured between the housing and slider. The at least one spring is positioned to apply a spring force to the at least one rack toward the neutral position when the at least one rack is in the displaced position.
