A self-locking latch assembly for a two-piece container is provided. The latch assembly has a latch hook pivotably biased in a parallel orientation to the first piece of the two-piece container, while a keeper is connected though spaced apart from the surface of the second piece of the two-piece container. The two-piece container is adapted to move between an open and closed position by sliding an open end of the larger piece over an open end of a smaller piece. During this sliding action, toward the closed position, a tapered edge of the latch hook strikes the keeper and is urged upward until the tapered edge ends, whereby the biasing of the latch hook urges it to engage the keeper in a locked condition. To unlock the latch hook, one can pivot it to a nonparallel orientation and slide the two pieces apart.

An opening and closing device is provided, including a fixing device and a limiting device. The fixing device includes a fixing portion and a fixing member, and the limiting device includes a driving device, a limiting portion, and a limiting member. The fixing member may rotate to be engaged with the fixing portion. The driving device is disposed on a first shell. The limiting portion is disposed on an inner side of the first shell. The limiting member is disposed on an inner side of a second shell. When the first shell approaches the second shell, the limiting member end portion may be engaged with the limiting portion. The driving device may be subjected to an external force to release the engagement between the fixing member and the fixing portion and the engagement between the limiting member end portion and the limiting portion.

Provided are a lock tongue module and a modular lockset, relating to the technical field of modular locksets. The lock tongue module includes a base, a lock tongue, a lock block, a first elastic member and a second elastic member. The lock tongue is pivotally connected to the base and has a locking position in which the lock tongue is capable of locking a lock catch and an unlocking position in which the lock tongue is capable of releasing the lock catch. The lock block is movably connected to the base.

Locking device having first and second combined connection carriers for establishing a detachable connection. A rotation element is rotatably attached at the first connection carrier and is provided in an inner region thereof. The inner region is centered with respect to a center axis and has a full radius. Elastic blocking heads are attached at the first connection carrier at the inner region, and are movable from a blocking to a release position. The rotation element includes segments extending up to the full radius and segments extending at a maximum up to a smaller inner radius. The segments extending up to the full radius move blocking heads into the release position and the segments extending up to the inner radius leave blocking heads in the blocking position. Key tongues move bordering ones of the blocking heads into the release position and allow rotation of the rotation element.

A container having a base and a lid is provided. The lid may be rotatable about a hinge from a closed configuration to an open configuration and may be secured, via one or more latching assemblies. The latching assembly may comprise a latch body, a locking member, a biasing member, and an activating member. Additional features of the container may include handles and strength increasing features. The base and lid may also feature attachment points for various accessories. A carry strap may attach to the base of the container to allow a user to lift and carry the container. The container may also have a wheels attached to the bottom portion and/or across the bottom portion to one side of the sidewall structure. In addition, in exemplary containers with wheels, a pull handle may be attached to a side opposite the wheels. The lid may include a lid support member that can act as a molle board to releasably secure items to the lid support member while also providing structural support to the lid.

A wheelchair armrest storage system may include a housing for a wheelchair, where: the housing includes a proximal portion, a distal portion, a first lateral side, and a second lateral side, the housing extends longitudinally between the proximal portion and the distal portion, and at least one cover receiving cavity is defined in each of the first lateral side and the second lateral side. The wheelchair armrest storage system may further include a storage area defined within the housing, and a cover configured to translate within each of the at least one cover receiving cavity defined in each of the first lateral side and the second lateral side.

The present invention discloses a thermal box comprising a body; the body comprises a box body, a box cover and locking devices provided on a front side and a rear side of the body respectively; the snap fastening seat is fixed on the box body; two extended lugs are provided on the box cover; the snap fastening seat is provided with a pivot seat between the two extended lugs; two mounting lugs are provided on a top side of the snap fastening member; the two extended lugs are positioned between the two mounting lugs and interconnected thereto via a rotating shaft to rotate inwards and outwards; a fastening structure which fastens by pressing inwards and unfastens by pulling outwards is provided on the inner side of the snap fastening member and the snap fastening seat.

Locking device having first and second combined connection carriers for establishing a detachable connection. A rotation element is rotatably attached at the first connection carrier and is provided in an inner region thereof. The inner region is centered with respect to a center axis and has a full radius. Elastic blocking heads are attached at the first connection carrier at the inner region, and are movable from a blocking to a release position. The rotation element includes segments extending up to the full radius and segments extending at a maximum up to a smaller inner radius. The segments extending up to the full radius move blocking heads into the release position and the segments extending up to the inner radius leave blocking heads in the blocking position. Key tongues move bordering ones of the blocking heads into the release position and allow rotation of the rotation element.

A locking module for selectively coupling a first component and a second component of a lockable device includes an opening formed in the first component. A locking member is rotatable about an axis between an unlocked position and a locked position. The locking member includes a feature selectively receivable within the opening. An engagement mechanism is operable to rotate the locking member about the axis between the unlocked position and the locked position.

A wheelchair armrest storage system may include a housing for a wheelchair, where: the housing includes a proximal portion, a distal portion, a first lateral side, and a second lateral side, the housing extends longitudinally between the proximal portion and the distal portion, and at least one cover receiving cavity is defined in each of the first lateral side and the second lateral side. The wheelchair armrest storage system may further include a storage area defined within the housing, and a cover configured to translate within each of the at least one cover receiving cavity defined in each of the first lateral side and the second lateral side.
