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.

A gravity-actuated latch mechanism is provided. The gravity-actuated latch mechanism may include a strike attached to a lid of a container and a latch body attached to an inside wall of the container. The latch body includes a housing and a catch accessible from outside of the housing, wherein the catch engages and disengages with the strike. The latch body includes a lever having a lever arm moveable between an engaged and disengaged position. The engaged position is engaged with the catch and the disengaged position is disengaged with the catch. The latch body also includes a latch actuation ball housed in an elongated passage within the housing. The lever arm of the lever extends into the elongate passage, allowing the latch actuation ball to apply force to the lever arm to move the lever from the engaged to the disengaged position in response to tipping the container for dumping.

A gear train side latching mechanism may include a bracket having one or more guiding features, a handle mechanically coupled to the bracket via the one or more guiding features such that the handle is linearly movable with respect to the bracket, a rack mechanically coupled to the handle comprising a first plurality of gear teeth and configured to move linearly relative to the bracket in a fixed relation to the handle, a driving gear rotatably coupled to the bracket and comprising a compound circular spur gear having a second plurality of gear teeth on an outer diameter of the driving gear and a third plurality of gear teeth on an inner diameter of the driving gear, wherein the second plurality of gear teeth are mechanically coupled to the first plurality of gear teeth, and an actuator gear rotatably coupled to the bracket and comprising a fourth plurality of gear teeth mechanically coupled to the third plurality of gear teeth and further comprising one or more features configured to engage with a corresponding engagement feature of a mechanical member. The gear train side latching mechanism may be arranged such that linear motion of the handle relative to the bracket transmits mechanical energy to the actuator gear via the rack and the driving gear to cause the actuator gear to mechanically interact with the engagement feature to transmit mechanical energy to the engagement feature.

An exemplary closure system includes, among other things, a striker assembly, a latch assembly, and a hooked structure. In response to the striker assembly and the latch assembly being laterally displaced from each other, the hooked structure engages one of the striker assembly or the latch assembly to block separation of the striker assembly from the latch assembly. An exemplary latching method includes, among other things, engaging a hooked structure in response to a striker assembly being laterally displaced relative to a latch assembly. The engaging blocks the striker assembly from separating relative to the latch assembly.

A double lock, dual action gravity latch device to secure a gate in a closed position comprising a latch assembly including a pivotal latch member movable between a latched and unlatched position, a keeper assembly including a striker pin to maintain the gate in the closed position when the pivotal latch member in the latched position, a latch lock assembly including a lock assembly with a first lock and a second lock each independently movable between a locked position and an unlocked position disposed on opposite sides of the gate to selectively move a lock subassembly from a locked position to an unlocked position when either the first lock or second lock is moved from the locked position to the unlocked position, and move the lock subassembly from the unlocked position to the locked position when the unlocked lock is moved from the unlocked position to the locked position and a first latch actuator and a second latch actuator each movable between a first position and a second position disposed on opposite sides of the gate to selectively move the pivotal latch member when either the first lock or the second lock is moved from the locked position to the unlocked position moving the lock subassembly from the locked position to the unlocked position such that when either the first actuator assembly or the second actuator assembly is moved from the first position to the second position the pivotal latch member is moved from the latched position to the unlatched position to allow the gate to be opened.

The disclosed apparatus, systems and methods relate to a quick release grill guard further comprising at least one latching system configured for the quick release and pivot of the grill guard away from the vehicle grill face. The quick release grill guard may comprises a vehicle coupling portion, a clasped member an elongate bar and a clasping member. The clasping member may be constructed and arranged to be releasably engaged with the clasped member. Further, actuation of the elongate bar may cause the clasping member and clasped member to disengage.
