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 door travel limiting device includes a housing, a stop member, a compression spring, and a flexible member. The stop member is slidably received by the housing, and is slidable in first and second sliding directions, and has first and second ends respectively extending outwardly from different portions of the housing. The stop member is biased to slide in the first sliding direction, causing a portion proximate to its second end to normally retract into the housing. Extreme sliding positions of the stop member are limited by protrusions. A flexible member protrudes from the stop member to selectively engage portions of a housing track, to retain the second end of the stop member at an intermediate position between its first and second positions, when the stop member is first actuated to slide from the first position to the second position, and is then no longer actuated but biased.
