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 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.

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.

Adoor latch includes a gripper adjustable between a gripping state and a release state, which gripper, in the gripping state, is able to grip a closing member for holding the door closed which moves relatively closer to the gripper in a closing direction as a door of the domestic appliance is closed, and, in the release state, frees the closing member for opening the door, wherein, when the door is closed, the gripping state of the gripper is released by a relative releasing movement of the closing member carried out in the closing direction; and an electrically controllable displacement mechanism for displacing the gripper, under electrical control, from a retracted position into an advanced position against a restoring spring force, which advanced position, when the closing member is gripped, corresponds to a state in which the door is closed to a lesser degree than in the retracted position.

A door-equipped housing includes a box body having an opening formed on one side thereof, and a door to close the opening, the door being supported by the box body to be rotatable about a rotational axis. The box body has a projecting portion formed on an inside of a wall of the box body extending from the opening toward a deep side of the box body. The door includes a hook portion to engage the projected portion for preventing the door from opening, the hook portion being located on a deeper side of the box body than the projecting portion as the door closes the opening, and a flexible part extending in a direction away from a surface of the wall having the projected portion formed thereon as the door closes the opening. The flexible part bends together with a movement of the hook portion to climb over the projecting portion during an opening/closing operation of the door.

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 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.

PROBLEM: To provide a retaining device for which the magnitude of resistance when an engaging protrusion moves between elastic pieces can be adjusted. SOLUTION: The retaining device 4 is provided with: a receiving member 5 that is attached to a main body 1, and an engagement member 6 that is attached to a movable body 2. The receiving member 5 has: a base part 10 attached to the main body 1, a first elastic piece 11 supported by the base part 10, and a second elastic piece 12 supported by the base part 10. The engagement member 6 has an engaging protrusion 8 that passes between the first elastic piece 11 and the second elastic piece 12 and is retained at a retaining position P. An interval between the first elastic piece 11 and the second elastic piece 12 becomes narrower than the engaging protrusion 8 at a more forward side than the retaining position P. The first elastic piece 11 bends more easily than the second elastic piece 12 at a more forward side than the retaining position P.

A domestic dishwashing machine includes a machine body having a dishwashing chamber formed therein, a door for closing the dishwashing chamber, which door is mounted on the machine body so as to be pivotable about a horizontal pivot axis close to the floor, and a door latch for holding the door closed, having a latch assembly installed in a body roof above the dishwashing chamber and includes a one-piece closing member arranged to be movable between an open position and a closed position, and a closing spring arrangement supported on the closing member and which, in the open position of the closing member, urges the closing member into blocking engagement with a blocking surface that prevents relaxation of the closing spring arrangement, and comes into gripping engagement with an engagement structure arranged on the door and pulls the door shut under the action5 of the relaxing closing spring arrangement.

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 lock and an electrical appliance using the door lock. The door lock comprises: a switch housing; a pen core-like mechanism disposed in the switch housing; a control needle (state means) passing out of the pen core-like mechanism; and a manual unlocking pull rod mechanism. The manual unlocking pull rod mechanism is capable of moving towards the control needle and coming into contact therewith. The position of the control needle (state means) indicates the switch state of the door lock, such that when the door lock is in an unlocked position, further pulling of the manual unlocking pull rod mechanism has no effect on the door lock switch mechanism.
