An electronic drive for a lock assembly includes a housing, a motor disposed within the housing, and at least one link bar coupled to the motor. The at least one link bar at least partially extends out of the housing. The electronic drive also includes a driven disk coupled to a first end of the at least one link bar and rotatable about a rotational axis. The driven disk is adapted to couple to the lock assembly, and upon rotation, extend and retract at least one locking element. In operation, the motor selectively drives substantially linear movement of the at least one link bar to rotate the driven disk about the rotational axis.

In general, one aspect of the subject matter described in this specification is embodied in a latch. The latch includes a ball joint. The ball joint includes a stem and a first ball positioned at a proximal end of the stem. The latch includes a casing that is configured to surround a portion of the stem and the first ball and secures the ball joint within an enclosure. The latch further includes a cap plate. The cap plate has a recess or cup that receives the first ball of the ball joint and allows the first ball to swivel within the recess or cup.

A neonatal incubator system includes an enclosure having side panels that create a chamber that receives an infant. At least one of the side panels is movable between an upright closed position and a retracted open position. A side panel latch assembly is positioned to permit and prevent movement of the movable side panel between the open and closed positions. The side panel latch assembly includes a movable latch lever having a primary latch member and a secondary latch member that are spaced from each other. The primary latch member engages a first catch on a latch receptable to hold the side panel latch assembly in the latched position. The secondary latch member engages a second catch on the latch receptacle when the side panel is partially open. The primary and secondary latch members move together with the latch lever to release both the primary and secondary latch members.

A latching system for securing a door to a panel includes a pawl having a first end that is configured to releasably engage a striker on the panel, and a second end opposite the first end having a connector. A pawl connector is connected to the connector on the second end of the pawl. The pawl connector includes a hollow cylindrical body having a longitudinal axis, a revolved outer side wall extending about the longitudinal axis, an open end through which the connector of the pawl is positioned, an opening defined on the revolved side wall of the cylindrical body, and a deformable portion formed on the revolved outer side wall. The deformable portion extends between the open end and the opening. The deformable portion is configured to elastically deform upon inserting the connector through the open end until the connector is non-removably seated within the opening.

Disclosed is door guardrail. The door guardrail includes a door guardrail body having an opening; a movable baffle movably mounted on and movable relative to the door guardrail body to open or close the opening; and a locking device, arranged on the movable baffle or the door guardrail body; and wherein the locking device is capable of limiting or releasing the movement of the movable baffle relative to the door guardrail body.

The invention relates to a device (200) for locking a door, which comprises: a bolt (40) comprising a bar (52) configured to engage in a housing secured to the frame (80) accommodating the door and a pusher means secured to the bar (41) and spaced apart from the bar by a stem and in which the bolt is positioned on the door at a height relative to the foot of the door of between thirty and eighty centimetres, such that the bar of the bolt can be engaged with or disengaged from the housing secured to the frame by pressure applied by a user's knee against the pusher means.

Various disclosed embodiments include a lock assembly. The lock assembly includes a lock bolt. The lock bolt has a lock bolt body and having a bolt security engagement feature formed as part of the lock bolt body. The lock assembly also includes a receiver. The receiver has a receiving area for receiving at least a portion of the lock bolt and the receiver has a receiver security engagement feature formed as part of the receiver. The receiver security engagement feature is complementary to the lock bolt security engagement feature.

An adjustable door lock may include a catch plate adapted to be secured adjacent to the door. A plurality of catch brackets may be connected to the catch plate. A catch may be adjustably connected to the catch plate and interfitted through the catch brackets. Such a catch preferably has a linear channel formed therein. A door plate may be disposed adjacent to the catch plate and adapted to be secured to the door. A locking bolt may further be housed within the door plate and may be linearly reciprocated along a first linear path passing through the door plate and the linear channel. In this way, the catch may be automatically adjusted along a second linear path orthogonally registered relative to the first linear path such that the linear channel automatically becomes axially aligned with the locking bolt as the locking bolt ingresses and egresses the catch.

A latch mechanism includes a main body engagement unit arranged in a main body having an opening/closing body that opens/closes, and opening/closing body engagement unit arranged in the opening/closing body to engage with the main body engagement unit when the opening/closing body is closed, in which the main body engagement unit is configured to include a first engagement body having a pair of first top portions displaced in a direction orthogonal to a closing direction of the opening/closing body, the opening/closing body engagement unit is configured to include a second engagement body having a pair of second top portions respectively coming into contact with the pair of first top portions, and the second engagement body has a first slope that applies a force in a direction to open the opening/closing body to the second engagement body in a state where the other first top portion of the pair of first top portions is in contact with the second top portion, when one second top portion of the pair of second top portions comes into contact with one first top portion of the pair of first top portions while the opening/closing body is closed.
