An exemplary product line system includes a common platform and a plurality of component families, each of which includes a plurality of interchangeable component species configured for use with the common platform. The common platform includes an inside drive assembly and a chassis assembly including a chassis and an outside drive assembly. A lockset assembled from the system includes the common platform and a plurality of modular components. Each of the modular components corresponds to a respective one of the component families, and is provided as a selected species of the corresponding component family. The lockset has a function defined by the set of component species installed to the lockset. The function of the lockset can be changed by altering the set of component species installed to the lockset without disassembling the chassis assembly.

A door bolt lock structure contains: a casing, a drive element, a slide plate, and a head. The casing includes a cavity and a locking orifice. The drive element is accommodated in the cavity and includes a lock cylinder and a control lever. The slide plate slidably is received in the drive element and includes a holder, a groove, a free segment, a first locating orifice, and a second locating orifice. The head includes a trench and a threaded orifice, such that the threaded orifice is selectively aligned with the first locating orifice or the second locating orifice of the slide plate, and a second screw element is inserted through the locking orifice of the casing, the first locating orifice or the second locating orifice, and the threaded orifice of the head so as to adjustably move the head with respect to the slide plate.

A bolt lock comprises a lock body and a bolt which is lockable to the lock body. The lock body comprises a housing and a lock cylinder therein, a movable latch and a biasing spring. The housing comprises an introduction passage for the bolt. In a locking position, the latch engages a locking recess of the bolt and hereby locks the bolt. The biasing spring biases the latch in the direction of the locking position. The housing and the latch comprise a respective blocking section, wherein the blocking section of the housing and the blocking section of the latch are configured so as to engage with one another and hereby block the latch against movement from the locking position in the direction of an unlocking position, when a force, via the bolt introduced into the introduction passage, is exerted on the latch which is in the locking position, the force being counter to the introduction direction of the bolt. The biasing spring is oriented at an angle such that the biasing spring additionally biases the latch along the introduction direction of the bolt.

A door lock chassis has a gauge insert that defines different dimensions corresponding to different door thicknesses. The gauge insert is positionable in the lock chassis in different orientations corresponding to the different dimensions used to align the lock chassis for different door thicknesses. Additionally, a door lock may include an anti-rotation assembly for preventing rotation of the lock chassis. The anti-rotation assembly may include a retention member that is secured to an inside hub of a lock chassis. As an anti-rotation member is displaced in a first axial direction along the inside hub to a mount position, the anti-rotational member may deflect resilient members of the retention member. With the anti-rotation member at the mounted position, the anti-rotation member may be in a frictional engagement with the previously deflected resilient members so that anti-rotation member is retained at the mount position.

In one form, a cylindrical lockset includes a chassis including a pair of hubs, a pair of drive tubes, a retractor, and a lock control assembly. The lock control assembly has a locked state and an unlocked state. The lock control assembly also has a plurality of movable elements, each having a locking position and an unlocking position. One of the hubs includes a guide channel, and a slider is movably seated in the guide channel. One of the movable elements is associated with the slider, and is configured to move the slider between a lock-indicating position and an unlock-indicating position.

A door body structure and a cooking device are provided. The cooking device has a housing that includes a limiting portion. The door body structure has a door body, an engagement member, a switching member, and a handle. The door body is arranged on the housing. The engagement member is arranged on the door body and has a hook. The hook is configured to be engaged with or disengaged from the limiting portion. The switching member is configured to cooperate with the engagement member to drive the engagement member to move between a first position and a second position. The switching member has a connecting segment connected to the engagement member and an operating member slidingly engaged with the connecting segment. The handle is provided on the door body and has a locking groove defined therein.

An elevated hunting or observation blind enclosure formed by interconnected outer walls. A door is pivotally mounted to one of the outer walls to span substantially span from the top to the bottom of the one outer wall. The door is hinged at its top edge to swing out from a vertical closed position to an open position permitting unobstructed entrance and exit by a user.

A locking device (1), comprising:—a latch bolt arrangement (2), which is movable into at least a first and a second latch bolt position, said latch bolt arrangement (2) comprising a first follower arm engagement part (7); —a first follower arrangement (8) configured for transferring a motion to the latch bolt arrangement from a first unlocking device which can be connected to the first follower arrangement (8), wherein said first follower arrangement (8) comprises a first follower arm (11) which comprises a latch bolt engagement part (13) which is configured to at least in some positions of the first follower arm (11) contact the first follower arm engagement part (7) of the latch bolt arrangement (2), whereby the latch bolt arrangement (2) can be pushed by a movement of the first follower arm (11) such that the latch bolt arrangement (2) is moved from the first latch bolt position to the second latch bolt position; and —a locking arm (15), wherein said locking arm (15) further comprises a locking arm catch (19), whereby said locking arm (15) can be moved from the first locking arm position to the second locking arm position by pushing said locking arm catch (19), and wherein the first follower arm (11) further comprises a locking arm catch engagement part (21) which will push the locking arm catch (19) for moving the locking arm (15) towards the second locking arm position when the first follower arm (11) is moved for pushing the latch bolt arrangement (2) to the second latch bolt position.
