This design solves the problems existing in current locks, reduces the lock body size, reduces operating space, and shortens the operating stroke.

Disclosed are a locking mechanism and a locking apparatus. The locking mechanism is operable to securely lock a detachable attachment. A bolt is connected to a drive and also rotatably connected to a securing rack; the drive may be subjected to an external force to slide relative to the securing rack, which drives the bolt to rotate, so that a snap hook of the bolt may access and exit a locking bore, whereby locking or unlocking is realized. A snap hook according to the disclosure may extend out of the locking bore to snap-fit the detachable attachment outside the housing, realizing positionally retaining of the bolt in multiple directions, which eliminates a need of additionally setting a limiting mechanism to extend the bolt outside of the housing to lock the detachable attachment, which facilitates use and offers a strong practicality.

A lockset including a chassis having a locked state and an unlocked state, a latchbolt connected with the chassis, a handle mounted to the chassis, and a lock cylinder connected with the chassis. The handle is operable to retract the latchbolt when the chassis is unlocked, and is inoperable to retract the latchbolt when the chassis is locked. The lock cylinder includes a shell and a plug selectively rotatable relative to the shell. The chassis is configured to transition from the locked state to the unlocked state in response to rotation of the plug in a first rotational direction from a home position to a first rotated position. The chassis is configured to return from the unlocked state to the locked state in response to rotation of the plug in a second rotational direction from the first rotated position to the home position.

A fenestration assembly includes a fenestration frame having a frame core. The frame core includes a core exterior face and a core interior face. A core wall of the frame core includes filament reinforced polymer, and the core wall extends between the core exterior face and the core interior face. One or more core cavities are within the frame core and surrounded by the core wall. At least one insulation scaffold is seated within the one or more cavities. The insulation scaffold includes one or more scaffold walls and scaffold cavities bordered by the one or more scaffold walls. Engagement feet are coupled with the remainder of the insulation scaffold, and the engagement feet are engaged against the core wall.

The invention relates to a lock (1) which, in the locking position, engages with bolts (3, 9, 10, 13) that are movable via a driving-rod slide (15), in locking plates (36) on the frame side, wherein at least one bolt (10) is designed as a cylindrical latch bolt (13) which can be pre-locked perpendicular to a rebate surface and which can be closed forwards and backwards along its latch axis (21) via the driving-rod slide (15), wherein the latch bolt (13) engages with a link follower (23) in a link (24) of the driving-rod slide (15). In order to provide an effective push-back protection which can be solidly constructed and avoids the disadvantage of the prior art, according to the invention the latch bolt (13) has a locking edge (22) which runs inclined to the latch axis (21) and is associated with a wedge edge (30) of a locking wedge (29) which runs parallel to said locking edge and can be displaced parallel to the driving-rod slide (15) and which is supported on a rear wall (31) of the housing.

A locking mechanism for a rack comprising: a locking tab; a rotating locking pin; a locking tooth; a rotation biasing member and an angular rotation restriction assembly. The locking pin extends along a longitudinal axis and is rotatable thereabout. It is longitudinally movable along the longitudinal axis as the rack is moved into the transport configuration or away therefrom. It includes the locking tooth at a distal end thereof and is rotatable between a locking angular orientation and an unlocked angular orientation. The rotation biasing member torsionally biases the rotating locking pin into the locking angular orientation. The angular rotation restriction assembly is activatable when the rotating locking pin is rotated into the unlocked angular orientation and the rack is configured in the transport configuration and is configured to temporarily maintain the rotating locking pin in the unlocked angular orientation.

The invention relates to a locking mechanism provided and adapted to interact with at least one locking element to establish a lock between the locking mechanism and the locking element, wherein the locking mechanism comprises a first locking pawl and a second locking pawl, which are independently rotatable from each other about a first rotation axis, wherein the first locking pawl is arranged and adapted to interact with a first locking element, and wherein the second locking pawl is arranged and adapted to interact with a second locking element, wherein a secure lock exists when the first locking element is locked to the first locking pawl and the second locking element is locked to the second locking pawl.

The present invention provides a locking mechanism and a locking device, the locking mechanism being used for locking and securing a detachable optional assembly. The locking mechanism comprises: a housing detachably connected to the detachable optional assembly, a fixing frame mounted in the housing, a driving assembly slidably connected to the fixing frame, and a lock tongue movably connected to the driving assembly. The housing is provided with a locking hole. The fixing frame is provided with a first locating shaft. The lock tongue is rotatably connected to the first locating shaft, and a curved hook adapted to the locking hole is formed at the end of the lock tongue away from the first locating shaft. The driving assembly is used for driving the lock tongue to rotate about the first locating shaft from a first position to a second position, wherein when the lock tongue rotates to the first position, the hook is located inside the housing, and when the lock tongue rotates to the second position, one end of the hook extends through the locking hole to fasten and secure the detachable optional assembly outside the housing. The locking mechanism of the present application allows the locking mechanism to lock and secure a detachable optional assembly within a housing.
