A product dispenser comprises first and second housing parts (11, 12) and a lock mechanism. The lock mechanism is configured to lock the first and second housing parts together with one another, and comprises: a cradle (30), the cradle housing at least one lock arm (20); an aperture (80) through the first housing part and leading into the cradle; a rotatable guiding part (40) located within the aperture and the cradle; a key (70) that cooperates with the rotatable guiding part; and a mating part of the second housing part, the mating part configured to engage with an end (21) of each lock arm to lock the first and second housing parts together, and wherein the key is rotatable to rotate the rotatable guiding part within the aperture and actuate each lock arm to disengage from the mating part, unlocking the first and second housing parts from one another.

A latch structure comprising an elastic pull latch is disclosed. The top of the elastic pull latch includes a latch bar configured with a latch groove. The elastic pull latch also includes an elastic boss that moves in and out of the latch cover of the pull latch. On both sides of a box, an elastic pull latch is provided at the top and a catch groove having a catch affixed to the lower edge is provided at the bottom. When two boxes are stacked together, the catch in the catch groove of the upper box is snapped into the latch groove of the elastic pull latch of the lower box to securely connect the two boxes. When the latch is released, the catch of the upper box blocks the elastic boss of the latch of the lower box to prevent the latch from retracting inwards.

A diaphragm latch may comprise a housing, a diaphragm disposed in the housing, a pin coupled to the diaphragm, an opening in the housing, and a pin aperture disposed in the first side, wherein the pin extends from the pin aperture. The diaphragm may be configured to move in response to a pressure being communicated through the opening, and the pin may be configured to at least one of extend or retract from the pin aperture in response to the diaphragm moving. The diaphragm latch may passively couple an inner fixed structure (IFS) to an intermediate case (IMC) during an overpressure event.

A plastic arrangement that includes a first plastic component, a second plastic component, and a plastic lock mechanism for fastening the second plastic component to the first plastic component. The plastic lock mechanism includes a first lock unit and a second lock unit. The first lock unit includes a U-shaped cantilever member, a catch element and a catch element retention part. The second lock unit includes a protruding member and a protruding member retention part. The plastic lock mechanism provides a locked position wherein the catch element retention part restricts movement of the catch element for preventing the second plastic component from separating from the first plastic component, and the protruding member retention part restricts movement of the protruding member for hindering the moving of the first lock unit to a released position.

Apparatus and associated methods relate to a selectively operated safety latch having an active mode and a stowed mode. In an illustrative example, a retractable safety latch may include a tongue element extending in a first plane and a base element extending in a second plane. The tongue element, for example, may include multiple mode selection slots. The base element may include a brace slot. For example, one of the multiple mode selection slots and the brace slot may receive a security pin long a longitudinal axis so that a predetermined mode is selected. In the active mode, the tongue element extends away from the base element to releasably engage a striker element. In the inactive mode, the first plane and the second plane are substantially parallel such that the tongue element is prevented from engaging the striker element. Various embodiments may advantageously provide quick switching security latch operations.

A latching mechanism can secure one or more moveable members in a cabinet. The latching mechanism includes a support having a back plate mounted to the moveable member and having an opening extending therethrough, an end cap attached to the support and having a mating stem that extends into the support, and a latch having a leading end that extends through the opening in the back plate and a trailing end having a mating bore that is sized to receive the mating stem of the end cap. The mating bore of the latch defines a pivotal axis. The latch is configured to pivot along the pivotal axis between an open position in which the moveable member is moveable in the cabinet and a closed position in which the latch prevents the moveable member from moving away from the cabinet. A locking mechanism for this type of cabinet is also provided.

A door assembly for an animal enclosure includes a door frame and a door each having a plurality of interconnected horizontal and vertical wires. The door frame defines an opening for an animal to pass therethrough, and the door is slidably coupled to the door frame such that it moves between an open position and a closed position relative to the door frame to allow egress and ingress through the opening. A catch member is coupled to the door frame. A latch includes a base member, a bolt, and a lever portion. A first vertical wire and a second vertical wire of the door are spaced from one another such that the first vertical wire is at a first end of the door and the second vertical wire is at a second end of the door. In the closed position, the bolt is coupled to the first vertical wire.
