A combination sash lock and tilt latch in one integral fastener may suitably secure a sash window that is slidable and tiltable with respect to a master window frame. The fastener includes a lock assembly and latch assembly. The lock assembly is releasably mounted upon the meeting rail of the sash window without screws, using legs received within corresponding openings in the rail. The lock assembly is secured thereto by a biasing member causing engagement between the legs and rail openings. The lock assembly includes a pivotable cam to releasably engage a keeper on the master frame, and a pivotable arm extending into the meeting rail. The latch assembly includes biasing means and a latch member, which includes a fixed funnel member and a flexible funnel member on a distal end of a flexible beam, to blindly engage the lock assembly arm within the meeting rail, when installed therein.

A casing that has a generally cylindrical configuration having a bottom side that includes a bottom side cavity. The bottom side has a topography that is generally a negative topography of a surface of an article with which the bottom side associates. The topography of the bottom side is defined by a plurality of offset surfaces that define raised edges, with the offset surfaces and resulting raised edges forming reliefs.

An internally dismantled anti-typhoon soundproof horizontal sliding window, which is fastened to an outer frame body and is provided with at least one outer sliding window and an inner sliding window; it is characterized in that: the outer side of the outer frame body is provided with at least one outer fixing column, an elastically movable top plate is provided on the inside and outside of the outer fixed column; when the two windows are closed, a central control lock can be used to drive the top plate to move through the inner columns of the outer and inner windows inwardly, the top plate squeezes the two inner column clamps tightly; the outer column of the outer frame body is provided with a hook, which can be used for the outer sliding window and the outer column of the inner sliding window; a snap cover that seals the grooves of the outer frame; thus, the window structure can be tightly closed in an all-round way, so as to meet the requirements of windproof, rainproof and sound insulation of the strong typhoon level.

A tamper-proof lock includes: a housing, shaft/handle, cam, lever, spring, and plate. The shaft is pivotally mounted in a housing orifice, with the cam pivotally mounted to the shaft. The cam has first and second shaped openings at first and second respective radial positions, and an arcuate recess. The lever is secured to the shaft, and has a protrusion that alternately engages each of first and second ends of the arcuate recess to respectively/selectively drive the cam to rotate/counter-rotate in first and second directions, into locked and unlocked cam positions. The spring biases the plate for a protrusion thereon to be respectively received within each of first and second shaped cam openings, when aligned therewith at those cam positions, and for a curved surface of the plate to be correspondingly received within first and second curved cam recesses, respectively, when aligned therewith, which facilitate withdrawal of the plate protrusion.

An apparatus has a housing adapted to be secured to a window sash. A cam rotatably mounted in the housing has a cam surface and a cam boss disposed opposite the cam surface. A drive disc rotatably mounted proximate the cam has a disc boss and a projection disposed opposite the disc boss. The cam boss and disc boss are selectively engageable when the cam is rotated.

A refrigerator appliance includes a cabinet forming a receiving space; a door to provide selective access to the receiving space; an icebox at least partially received within the receiving space; an icebox door providing selective access to the icebox; and a latch rotatably coupled to the icebox door to selectively secure the icebox door to the icebox. The latch includes a main body defining a pivot point; a handle attached to the main body; a latch hook spaced apart from the pivot point along the radial direction by a first distance and extending clockwise along the circumferential direction; and a hammer spaced apart from the pivot point along the radial direction opposite the latch hook by a second distance shorter than the first distance, the hammer extending counterclockwise along the circumferential direction.

An apparatus has a housing adapted to be secured to a window sash. A cam rotatably mounted in the housing has a cam surface and a cam boss disposed opposite the cam surface. A drive disc rotatably mounted proximate the cam has a disc boss and a projection disposed opposite the disc boss. The cam boss and disc boss are selectively engageable when the cam is rotated.

A sash window fastener includes: a latch assembly; a sash lock assembly mounted upon the meeting rail; and a stop member mounted to the master window frame. The lock assembly includes a pivotable cam to engage a keeper on the master frame to lock the window, and a pivotable follower arm. The arm interconnects with the latch assembly within the meeting rail, so cam rotation that drives arm rotation also causes translation of the latch. The cam may occupy: an extended position to secure the cam to the keeper, with the latch engaging the master frame to prevent tilting, and being positioned below a protrusion on the stop member to redundantly lock the window; a first retracted cam position permitting sliding of the window; and a second retracted position permitting tilting of the sash window. Additional protrusions may be used on the stop member to serve as vent stop positions.

A barrier that includes four structurally different corner connections for fixing a gate frame of the barrier to and between opposing vertical surfaces. A first connection includes a headed straight pin engaging a pivot hook and socket, a second connection includes a headed straight pin engaging a socket, a third connection includes headless bent pin engaging a socket and a limiter, and a fourth connection includes a headless bent pin engaging a socket.

A medical appliance, in particular an apparatus for extracorporeal blood treatment, has a housing including a door and with a handle mechanism arranged at the door, via which the door can be locked with the housing via a locking mechanism. A part of the locking mechanism is formed at the handle mechanism in a part thereof that protrudes into the housing. A form-fit unit includes at least one form-fit element and at least one form-fit element counterpart, such that on locking and/or closing the door, the at least one form-fit element at least partly engages in the at least one form-fit element counterpart.
