A sash window restrictor (20) has a housing (22) which is to be let into a vertical frame member (10) of one sash (normally the upper, outer sash) of a window, at a position, say, 10 cm above the top rail of the lower sash when the windows are closed. A tab (24) is mounted in the housing and can be retracted into the housing or extended from the housing. A mechanism acts between the tab and the housing and allows the tab to be pressed into the housing and held in the housing for a period of time before the tab is released to allow the tab to extend. With the tab extended, the lower sash (12) can be lifted until it reaches the tab (24) but no further, so that a 10 cm gap will be opened at the bottom of the window.

Latches including a slot having a length that allows a striker of the latch to move from a normal closed position downwardly toward the closed bottom of the slot into an over travel position.

Fenestration lock assemblies, fenestration units including the lock assemblies, and methods of assembling the lock assemblies. The lock assemblies use a cam and follower design that transfers rotary motion to a lock bolt that moves in translation between an extended/locked state and a retracted/unlocked state.

A rotary drive actuation system for actuating a latch including: an output shaft having a member affixed at one end of the output shaft for coupling to a component of the latch; a common drive element affixed to the output shaft at the other end of the output shaft; and a plurality of motors coupled to the common drive element for simultaneously driving the common drive element and the output shaft in a first rotary direction to effect actuation of the latch.

A container is disclosed that has a housing and a lid. The lid has a planar portion and a latch that is freely movable parallel to the planar portion of the lid. The latch has a retention feature and a first reference surface that is perpendicular to the planar portion of the lid. There is a latch mechanism coupled to the housing that has an engagement element configured to engage the retention feature of the latch and a first alignment feature having a first alignment surface. The first alignment feature is configured to laterally displace the latch in a first direction such that the first reference surface aligns with the first alignment surface when the lid is brought together with the housing with the fastener laterally displaced away from the engagement element in a second direction that is opposite to the first direction.

A latch having: a fork bolt movably mounted thereto; a detent lever movably mounted thereto, wherein the detent lever prevents the fork bolt from moving from a closed position to an open position when the detent lever is in a latched position; a bell crank lever movably mounted to the latch for movement between a first position and a second position, wherein the bell crank lever moves the detent lever from the latched position to the released position as the bell crank lever moves from the first position to the second position; a release lever movably mounted to the latch for movement between a first position and a second position; and an intermittent pin operatively coupled to bell crank lever and the release lever, wherein movement of the release lever is not transferred to the bell crank lever when the intermittent pin is in the second position.
