A door assembly includes an inner door panel and an outer door panel pivotable with respect to the inner door panel, the inner door panel including a latch base. The outer door panel includes a handle assembly including a handle endcap, a handle body rotatable with respect to the handle endcap, and a latch bar connected with the handle body, the latch bar being detachably coupled to the latch base. The outer door panel is rotatable with respect to the inner door panel, such that the outer door panel can be rotated away from the inner door panel.

A wire crate latch apparatus having, in a first embodiment, a pivoting member that is continually drawn to a closed position by gravity and that is deflected into a catch when the door having the pivoting member is swung closed. The latch apparatus further includes upper and lower stops to contain a distal end of the pivoting member and to hold the distal end in the position to hit an oblique portion of the catch when the door is closed. In a second embodiment, a sliding latch apparatus is deflected by a catch and is relatively inaccessible from inside of the wire crate by back plates on the latch and catch.

A frame includes sliding panels to cover an opening of a cabinet. The panels are mounted to interlocking stiffeners. Each of the interlocking stiffeners includes a base portion that forms a channel to receive a forward leading edge or a rear leading edge of the panels. The interlocking stiffeners share forces between the panels. A latch assembly may also be engaged to the interlocking stiffener attached to the forward leading edge of the panel. The latch assembly includes a protruding or projecting portion, such as a bullnose, that positions the latch assembly with respect to a side frame member. During a closing operation, the protruding portion enters a channel of the side frame member. The protruding portion engages with the channel of the side frame member, which results in proper alignment for the latch assembly.

A handle mechanism is to be mounted on a slidable plate and to slide the slidable plate relative to a chassis. The handle mechanism includes a handle and an engagement component. The handle is adapted to be pivotably disposed on the slidable plate so as to have an engaged position and a disengaged position. The engagement component is slidably disposed on the handle and adapted to contact the chassis to slide the slidable plate into the chassis. The engagement component has a contact surface, and the contact surface has an edge located away from an axis of the handle. A distance between the edge of the contact surface of the engagement component and the axis of the handle in the engaged position is smaller than a distance between the edge of the contact surface of the engagement component and the axis of the handle in the disengaged position.

A safety gate has a gate body and two first locking units. The gate body has two first connecting elements. The two first locking units are respectively mounted on two opposite sides of a door frame. Each first locking unit has a second connecting element and a blocking element. When the safety gate is closed, each of the first connecting elements is connected with a respective one of the second connecting elements. Each blocking element has a blocking position for blocking a corresponding first connecting element to prevent the corresponding first connecting element from being disengaged from the second connecting element and a pressed position to allow-the corresponding first connecting element to detach from the second connecting element of the first locking unit.

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.
