  • Patent number: 8375659
    Abstract: A handicap accessible doorway includes a frame having side jambs and a low profile sill extending between the bottom portions of the jambs. A flexible fin extends along the length of the sill and projects upwardly therefrom to form a water dam. The flexible fin is sealingly attached at each end to a jamb. During a blowing rainstorm, water is contained by the dam and directed to a contain-and-drain water management system, which directs the water away from the doorway to an exterior weep hole or other drain port. The fin, being flexible, yields to the weight of a footstep or a wheelchair thereby maintaining the handicap accessible designation of the sill and the doorway.

  • Publication number: 20060225354
    Abstract: A dual function lock, a tilt latch assembly, and tilt latch for use on a hung or double hung window are provided. The lock includes a base, a handle, and a tilt latch actuating mechanism. The tilt latch assembly includes a lock, left and right latches, and an extensible member. The tilt latch actuating mechanism is adapted to receive the extensible member and has a null zone between locked and unlocked positions of the handle. In the null zone, no substantial movement of the extensible member as the handle is rotated from the locked to unlocked positions. The tilt latch actuating mechanism causes the extensible member to move in a direction toward the lock as the handle is rotated from the unlocked position to a tilt position.
