Abstract: An improved window sash latch which has a locking mechanism and a keeper is provided with a handle that rotates from a “locked” to an “unlocked” position. An inner cavity of the handle has a spring assembly having a sliding part that can be forced into a detent as the handle slides around a cylindrical extension of an outer surface of the latch. The detents correspond to a “locked” and an “unlocked” position of the latch. The latch also provides two cams where both cams revolve relative to each other; one cam is activated by the handle through the handle's shaft, the other cam engages the keeper, and both cams engage each other.

Abstract: A vent stop is installed into a window/door to limit travel therein of a sash member, and being particularly adapted to permit ease of its installation, especially into a wooden door/window. The stop incorporates multiple retention features to inhibit the stop's removal, once properly installed. The retention features include a wedge-shaped protrusion located at a distal end of the stop housing, which engages the wood of the window opening when pivotally installed therein, to secure a first end of the stop. The opposite end of the stop may be redundantly secured. A first feature for securing the opposite end may comprise one or more arcuate flanges on housing side walls, flanges being adapted to unidirectional movement so as to permit its movement relative to the window opening during installation, but thereafter deterring counter-pivotal motion that would allow removal of the vent stop. A second feature comprises a deformable spring clip.

Abstract: A lock adapted for attachment to a sash window/door without screws comprises: a shaft with a cam secured thereon is rotatably secured to a housing, with the cam disposed within a housing cavity and rotatable therefrom out of an opening, into an extended position. The housing may be a single integrally formed wall that preferably has a flat bottom surface. A first attachment leg protrudes out from the housing cavity to extend beyond the bottom surface, with a foot thereon extending beyond a first end of the housing. A second attachment leg protrudes out the housing cavity second end, with a foot thereon oriented toward the housing first end, and a locking tab extends from the housing bottom surface. Installation of the screwless sash lock is by receiving the first foot, second foot, and locking tab within correspondingly positioned openings in the window/door rail, through sequenced rotational and sliding motion.

Abstract: A multi-point door latch adapted to fit in the stile of a door. The multi-point door latch includes a pair of hooks that are allowed to rotably pivot around a pair of eccentric cams. The eccentric cams are allowed to rotate inside of apertures located through the hubs of the hooks. The eccentric cams are geometrically centered inside the hubs of the hooks, and are kept in position via pins that are eccentrically orientated through cams. The multi-point door latch also includes an opening for receiving a turning mechanism. In addition, the turning mechanism is connected to a pair of toothed gear wheels that mesh with a toothed bar. The toothed bar is connected to a synchronizing link which simultaneously rotates the hooks to either an engaged or disengaged position. The multi-point door latch also includes stopping members, which prevent the hooks from rotating passed a certain point when the door latch is not engaged.
