A retraction device includes a housing and a driving element guided in the housing between a parked position and an end position. A first end of a spring energy accumulator is connected to the housing. The spring energy accumulator is loaded to a maximum operating value when the driving element is in the parked position and is unloaded to a residual energy value when the driving element is in the end position. A second end of the spring energy accumulator can either be fixed to the housing or coupled to the driving element by means of a bistable coupling. The coupling has a blocking element that can be moved between the housing and the driving element.

A laundry treating apparatus includes a cabinet with an outlet, a drawer drawn out from the outlet, a drum provided inside the drawer, providing a space where laundry is stored, a base fixed to the cabinet, a base slit provided in the base, including a linear portion and a first bent portion, a slider coupled to the base to move along the base, a slider slit, a conveyer, an operation unit fixed to the drawer and detachably coupled to the conveyer, and springs provided to connect the base with the slider and provided to move the slider toward a rear end of the linear portion if the conveyer moves from the first bent portion to the linear portion.

A self-close drawer mechanism includes a housing, a slidable self-close latch selectively positionable within the housing, a rotatable cam element in the housing, a flexible link system extending around the cam element, and a spring applying stored force to the sliding self-close latch through the flexible link. Dual cam surfaces in the cam elements realize a decreasing pull force as the user opens the drawer and provides smoother opening and closing operations with an improved user experience.

A drawer assembly includes a member having a first locking element. A drawer includes a frame and a handle having a first portion and a second portion. The first portion is coupled to the frame. The second portion is coupled to the first portion. A drawer release includes a first end and a second end and is rotatably coupled to the drawer. The first end includes a second locking element. The second portion is rotatable relative to the first portion to move the drawer release between a first orientation in which the second locking element directly engages the first locking element to prevent the drawer from translating relative to the member and a second orientation in which the second locking element is spaced apart from the first locking element to allow the drawer to translate relative to the member.

A retracting device includes a housing that is disposed in or on an accommodating unit to be pulled out from an apparatus including a protrusion and that has a groove extending from a first position to a second position and having an opening formed at the first position, the first position corresponding to a position of the protrusion when the accommodating unit moving in a direction in which the accommodating unit is accommodated into the apparatus reaches a predetermined position and the second position corresponding to a position of the protrusion when the accommodating unit is accommodated in the apparatus, and a movable unit that is disposed in the housing and that moves, when the accommodating unit reaches the predetermined position and the protrusion enters the opening, while holding the protrusion to cause the protrusion to move along the groove and with respect to the housing toward the second position.

A printer paper drawer door closing mechanism includes a fixed chassis defining a chassis plane, a lever arm joined to the chassis and pivotable about a lever arm pivot axis from a first lever arm limit state to a second lever arm limit state. A first bearing surface extends from the lever arm at a first lever arm distance and a second bearing surface extending from the lever arm at a second lever arm distance. The first bearing surface is at a bearing surface distance from the second bearing surface. An energy storage element is integrated with the lever arm. A cam plate is translatable toward and away from the lever arm and pivotable about a cam plate pivot axis from a first cam limit state to a second cam limit state. The cam plate includes a first cam surface extending from the cam plate and a second cam surface extending from the cam plate, the first cam surface being oriented at a positive angle relative to the copier chassis plane and co-planar with the first bearing surface, the second cam surface is oriented at a negative angle relative to the copier chassis plane and co-planar with the second bearing surface. The distance separating the first bearing surface and the second bearing surface is substantially equal to the distance separating a distal end of the first cam surface and a proximal end of the second cam surface.
