Abstract: A closure system for a sliding main door and a sliding screen door system of the type typically used in houses and some commercial buildings operates to permit three modes of operation of the sliding screen door and the sliding main door relative to one another. In a first mode of operation handles on the doors freely pass by one another and the two doors may be operated completely independently of one another. The handle on the sliding screen door is capable of movement to different vertical positions; and in another position, cooperating surfaces on the two handles cause the sliding screen door always to be closed when the main door is closed. When the main door is opened, however, the sliding screen door in this mode is capable of movement back and forth independently of the main door to the extent of the opening of the sliding main door.

Abstract: A door lock has a latch which is rotatable from a retracted position to an extended position by means of a linkage. A safety button extends from the latch when the latch is retracted. The linkage cannot be moved unless the safety button has been pressed, which occurs when the door is adjacent the door frame. This prevents the latch from extending and so damaging the keeper in the door frame. The linkage also has a notch which cooperates with a tang projecting from the housing. The tang an notch prevent the latch from being rotated from the extended position to the retracted position except by operation of the linkage. This feature makes it difficult to force the lock open without a key. In addition, one or more remote locks may be added to the main lock. With two remote locks it is possible to provide three anchor points for a door.

Abstract: A slam latch for securing a slidable window or door to a corresponding frame consists of a housing including a base plate, a catch and a keeper wherein the catch is spring biased downward against the housing so as to become operatively engaged with the keeper attached to the frame when the door or window is moved to a closed position causing the catch and keeper to become in juxtaposition to one another.

Abstract: The present invention provides an assembly for latching a moving panel relative to a frame in which the moving panel slides or glides. A keeper is secured to the frame, and a latch is secured to the moving panel in such a manner that the keeper and latch are adjacent one another when the moving panel is moved to a closed position within the frame. Rotation of a key or handle on the moving panel causes the latch to extend and capture the keeper and pull the moving panel toward the frame as it latches. The latch cannot capture the keeper until a spike extending from the frame deflects a button on the moving panel. When the moving panel is latched, the spike provides resistance to vertical movement of the moving panel relative to the frame.
