Abstract:
A closing device includes an actuator mechanism and a hydraulic damper mechanism. The actuator mechanism includes a pushrod urged by a resilient member towards its extended position. The hydraulic damper mechanism includes a piston, a first rack and pinion gearing for converting the translational motion of the pushrod into a rotational motion of a first pinion, a transmission, which includes a second rack and pinion gearing, between the first pinion and the piston for transmitting and converting the rotational motion of the first pinion into a translational motion of the piston, a one-way valve allowing fluid flow from a first side to a second side of the cylinder cavity when opening the hinged member, and a restricted fluid passage between the first and second sides of the cylinder cavity. The transmission provides together with the pinions of the first and second rack and pinion gearings a reduction gearing between the pushrod and the piston so that the piston reciprocates over a smaller distance than the pushrod.
Abstract:
The present invention relates to a door opening system for a domestic appliance (10) including at least one pivoting door (12). The door opening system comprises at least one door hinge (14) and at least one hook mechanism (16). The hook mechanism (16) includes a hook element (26) engaged or engageable with a recess (28) in a closed state of said door (12), so that the hook element (26) and the recess (28) form a snap-in mechanism. The hook element (26) is disengaged or disengageable from the recess (28) by operating a control element or said hook element (26). The door hinge (14) includes a stationary hinge part (18) and a pivoting hinge part (20). The stationary hinge part (18) is provided for a support structure of the domestic appliance (10), while the pivoting hinge part (20) is provided for the pivoting door (12). The stationary hinge part (18) is arranged or arrangeable horizontally inside or at the support structure of the domestic appliance (10). The stationary hinge part (18) comprises a first spring element (22) and a second spring element (24) provided for generating horizontal forces in the mounted state of the door hinge (14) at the domestic appliance (10). The first spring element (22) is provided for keeping the door (12) balanced within an outer opening angular range of said door (12). The second spring element (24) is provided for generating an opening force for the door (12) within an inner opening angular range, so that the door (12) is pushed into a partially opened state. The inner opening angular range extends between a closed state and the partially opened state of the door (12). The outer opening angular range extends between the partially opened state and a completely opened state of the door (12).
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 damps movement of the counterbalance assembly.
Abstract:
A device for opening and closing a movable window of a motor vehicle, the movable window being movable relative to a fixed panel, from a closed position in which the movable window is positioned flush with the fixed panel, to an open position in which the movable window is moved parallel to the fixed panel. The device includes an assembly controlled from a handle mechanism supported by an edge of a frame secured to the movable window, such that starting from the closed position, actuating the handle a first time releases locking of the movable window then, secondly, brings the movable window out of its closed position, an edge of the window corresponding to the edge of the frame being moved relative to the fixed panel, to the position allowing sliding of the movable window.
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 device is provided to assist the opening of a covering element pivotably mounted relative to an edge of a frame. The device includes an assistance cylinder (6). The assistance cylinder (6) includes a hollow shaft (7), a guide pin (10) inserted in the hollow shaft (7) and comprising at the end thereof opposite the end wall (8) of the hollow shaft (7) a yoke (11), a spring (13) inserted in the hollow shaft (7) surrounding the guide pin (10) and mounted pre-stressed when unloaded between the end wall (4) of the hollow shaft (7) and the yoke (11) of the guide pin (10), and a screw (14) secured to the end of the guide pin (10) and engaging with the end wall (8) of the hollow shaft (7) for keeping the pre-stressed spring (13) in the released state thereof. The invention is useful in the field of road systems.
