The disclosure relates to handle mechanism and casing assembly. The handle mechanism is adapted to be installed on a slidable plate body. The handle mechanism includes handle component, latch component, and releasing component. The handle component has engaged position. The handle component includes first hook portion and first pushing portion. The first hook portion has first contact surface. The latch component is slidably disposed and has second hook portion and first contact portion. The second hook portion has second contact surface configured to contact the first contact surface. The releasing component is pivotably disposed and has pressed portion and second pushing portion. When the handle component is pivoted from the engaged position, the first pushing portion pushes the pressed portion so as to force the second pushing portion to push the first contact portion so that the second contact surface is forced to leave the first contact surface.

A latch assembly is provided with a child lock mechanism having a spring system including a first spring member and a separate second spring member that requires a first force to move the child lock mechanism from an off position to an on position and a second force to move the child lock mechanism from the on position to the off position, wherein the required second force is greater than the required first force, thereby indicating to a user by tactile feedback the relative position (on/off) the child lock mechanism is in, thereby assuring intended movement of the child lock mechanism from one of the on/off positions to the other.

The invention is the method, system and apparatus provided for manufacturing a wallet that can be interactively designed and assembled/disassembled by the customer. There is a step for the user to communicate with the manufacturer by accessing the manufacturers portal through the designated communication channel(s); a step for selecting each part(s) desired, the material type for each part(s) selected and the color available for that material type and/or part(s); a step for the manufacturer to produce the selected part(s) in its material type and color using the latest manufacturing technology; a step for manufacturer to send the selected parts that are or can be assemble as, or into a wallet or send a part or set of part(s) for the user to assemble.

An attachment lock (27) for a prosthetic limb including a housing (28) having an opening (32) for insertion of a prosthetic locking pin (13). A locking member (29) is mounted within the housing (28) and is arranged releasably to secure an inserted locking pin (13). The lock (27) includes means (35) to adjust the position of the locking member (29) relative to the housing (28) along the axis of an inserted locking pin (13).

A lockable latch (8) is disclosed for walk-in cold rooms which includes a lockable strike (10) with an exterior strike assembly (16) and an interior release assembly (17). The exterior strike assembly includes a housing (25) and a rod holder (32) configured to releasably hold a coupling rod (35). The exterior strike assembly also has a metal anti-rotation plate (40) removably coupled to the housing. The interior release assembly includes a turn knob (53), an escutcheon plate (54), and an index washer (55). The turn knob includes two oppositely disposed alignment projections (77) and a radial array of steps (78) which includes four, re-occurring series of three steps. The index washer has a four time re-occurring series of steps (93).

The anti-theft device is configured in a door lock, and contains a first blocking piece, a second blocking device, a positioning piece, and a lever. The first blocking piece contains a first section and a second section bended and extended perpendicularly from the first section. The first section has a first through hole and a second through hole. The lever is engaged by a lock heart of the door lock. When the door lock is locked, the lock heart is turned to engage the lever so that the lever drives the first blocking piece downward by its first through hole. The second section of the first blocking piece as such blocks a lock tongue of the door lock so that the door lock cannot be opened without using key.

A connector assembly includes a connector body and a lock member. The connector body includes a plurality of walls, a locking arm, and an inner portion. The plurality of walls define a cavity configured to receive a terminal. The locking arm is coupled to a first wall of the plurality of walls and includes a first surface, a second surface opposite the first surface, and a lock tab extending from the first surface. The inner portion is disposed within the cavity. The lock member is removably-disposed within the cavity and defines an aperture configured to receive the terminal. In an assembled configuration, the locking arm inhibits removal of the lock member from the cavity, and the lock member is disposed between the lock tab and the inner portion.

Access control hardware for a door generally includes an exterior trim, an interior trim, and a plurality of lockset components housed within a cross-bore through the door. At least one of the plurality of the lockset components is a fire-rated component comprised of a fire-resistant material, such as steel or bronze. The fire rated component is configured so that at least one elongated component extending between the exterior trim and the interior trim extends through at least one fire-rated component. The fire-rated components interfaces with the at least one elongated component in order to reduce or eliminate space around the at least one elongated component through which light or flames may pass.
