Abstract:
A counterbalance assembly for an appliance hinge has a base including first and second spaced-apart side walls and a transverse face wall. A channel is located between the first and second side walls. First and second notch portions are respectively located in the first and second side walls. A rotating cam is supported on the base and has a camshaft that extends between the side walls and that is adapted for rotation about an axis of rotation, a first end located in the first notch portion and a second end located in the second notch portion. A biasing spring has an inner end engaged with the base and an outer end spaced from the base. A spring rod includes an outer end operatively coupled to the spring and an inner end operatively coupled to the lever. The lever also pivotally connects to the lobe of the cam. A damper assembly is connected to the base and having a piston which is moved between a first position and a second position by the lever contacting the piston. The piston in turn compresses fluid in the damper assembly thus dampening movement of the lid hinge.
Abstract:
The double-pivot synchronization is characterized in that each leaf is connected to an opening arm by an opening pivot. The other end of the opening arm is connected to a second pivot. This second pivot adds a degree of freedom to the components that are connected to it and thereby, frees them from the constraints imposed by the rotation of the leaves on the hinges. These components can thus be synchronized more easily. The mechanism comprises an arrangement of rigid elements, connected between them and attached to the frame.A first embodiment has a rail and is particularly suitable for manufacturers of furniture and cabinets who use custom-made components. A second embodiment, with rail, is better suited to a shallow frame and simplifies the adjustment to the width of the leaves. A robust and versatile third embodiment has gear teeth and mainly targets walk-through doors and recessed synchronization mechanisms.

Abstract:
The present subject matter provides an oven appliance. The oven appliance includes a pair of doors. A pair of sprockets or gears, a pair of chains, and a pair of connecting members couple the doors to each other such that the doors open and close simultaneously. The oven appliance also includes features for limiting or eliminating contact between the connecting members at a location where the connecting members cross each other.
Abstract:
A cantilevered folding gate (1) may be used with a module (13) which is suitable for fitting in such cantilevered folding gates (1) and includes a transmission mechanism (5) which is accommodated in a housing (14) and which is designed to transmit the movement of a first gate leaf (3) to a second leaf (4) so that the first (3) and second (4) gate leaf open or close simultaneously by folding.
Abstract:
A holding element for adjusting a lid (4) of a piece of furniture between a closed position and an open position has a first fitting part (1) that is connectable to the body (2) of a piece of furniture. A second fitting part (3) is connectable to the lid (4). A first support arm (5) is pivotably fastened around a first body axis (7) to the first fitting part (1) and is pivotably fastened around a first lid axis (8) to the second fitting part (3). A second support arm (6) is pivotably fastened around a second body axis (9) to the first fitting part (1) and is pivotably fastened around a second lid axis (10) to the second fitting part (3). A lever (19) is pivotably fastened around a pivot axis (20) to the first fitting part (1). An adjustment arm (26) is pivotably connected to the lever (19) at a distance from the pivot axis (20). The adjustment arm (26) is pivotably fastened around a third lid axis (28) to the second fitting part (3). A drive force (12) urges the lever (19), with a force, to a first pivot direction. In the open position of the lid (4), the first support arm (5) and the second support arm (6) intersect each other.
Abstract:
Described is a carriage (7) for sliding doors and windows (2) comprising a fixed frame (3), at least one sash (4) that is slidable horizontally relative to the fixed frame (3) by means of a carriage unit (1), and a handle (9) mounted on the sash (4) for controlling the carriage (7); the latter is provided with a supporting frame (11), mobile on wheels, and with a connecting member (13) interposed between the supporting frame (11) and a bottom sash (4) rail (8); the connecting member (13) is movably constrained to the supporting frame (11) to enable the sash (4) to be lifted and lowered relative to the supporting frame (11) under the action of the handle (9); a helical spring (44) is interposed between the supporting frame (11) and the connecting member (13) to lessen the effort required of the user to lift the sash (4).
Abstract:
A hinge mechanism (200) for a portable electronic device (100) is provided. The hinge mechanism includes a first shaft (202) that is capable of rotating about a first axis (206). The hinge mechanism also includes a second shaft (204) that is capable of rotating about a second axis (208), wherein the second axis in substantially parallel to the first axis. A link (210) connects the first shaft and the second shaft, wherein the link enables the first shaft and the second shaft to rotate in opposite directions.
Abstract:
A door closer comprising: (a) a housing for fitting into a door, the housing having a mounting plate with an opening adjacent to a central bore of the housing; (b) a tension member extending longitudinally within the central bore of the housing and extending outwardly of the housing through the opening to define an end thereof for fitting to a door frame; (c) a movable body within the housing and adapted for longitudinal movement within the central bore, the movable body being connected to the tension member; (d) a spring within the housing and biasing the movable body in a first direction away from the mounting plate so as to urge the tension member inwardly of the housing in a door closing motion; and (e) a hydraulic damping assembly for damping the longitudinal movement of the movable body at least in the first direction, the hydraulic damping assembly being disposed within the central bore of the housing, wherein the hydraulic damping assembly comprises a piston, coupled to the housing by a piston shaft, and slidable in a fluid-filled chamber within the movable body, the piston divides the chamber into two compartments and the piston permits restricted movement of the fluid from one compartment to the other when the movable body is moved relative to the piston, and an accumulator comprising a compressible foam body disposed in the fluid-filled chamber so as to be compressible by the piston when the movable body has been moved by movement of the tension member out of the housing, the compressible foam body comprising an elongate body having a channel in an outer circumferential surface thereof extending along the length of the elongate body. A fitting tool for the door closer is also provided.
