Abstract:
A hinge includes a housing. A sliding cam slideably received in the housing defines concave portions and an axial hole. A rotatable cam mating with the sliding cam has a base portion extending downward to form pushing portions disposed in the concave portions. The base portion defines an accommodating hole. A spring is slideably received in the housing. One end of the spring is fixed on the sliding cam and the other end of the spring is fixed at an end of the housing. A shaft received in the housing runs through the axial hole and the spring. An end of the shaft is received in the accommodating hole, and the other end of the shaft passes through the end of the housing. A first stop has a bottom surface whose part extends downward to form a blocking portion, and the rest part of the bottom surface is defined as a revolving platform. A second stop engaging with the rotatable cam has a top surface protruding upward to form a pushing block rotatablely disposed on the revolving platform. And a cap rotatablely receives the first stop and the second stop.
Abstract:
A magnetorheological clutch comprises a stationary part, a rotating primary part with primary laminated strips and a secondary part with secondary laminated strips, whereby a controllable magnetic field acts upon the magnetorheological fluid. The aim of the invention is to allow transmission of a highest possible torque in a smallest possible space and with minimal power consumption. Said aim is achieved, whereby a number of solenoid coils, each having a first yoke with a substantially radial winding axis, are alternately oppositely polarized; the first yokes have cylindrical front faces, whereby the magnetic field lines radially enter and exit said yokes, the primary laminated strips and secondary laminated strips form closed cylindrical envelopes and second outer and inner yokes are provided radially outside of and radially inside the first yokes, whereby the magnetic field lines radially enter the second yokes and radially exit said yokes in the opposite direction.
Abstract:
A floating damper assembly operates between first and second associated components. A damper is adjustably mounted in the first component and includes a damper gear engaged with a gear on the second component. The second component defines a guide surface and the damper has a bearing surface engaging the guide surface.
Abstract:
A door closer includes a body formed with a cylinder and a piston system located in the cylinder and functionally connectable to the door. The piston system divides the cylinder into a first cylinder volume on a first side of the piston system and a second cylinder volume on a second side of the piston system. A spring located in the second cylinder volume. A flow channel formed in the body guides flow of fluid from the first cylinder volume to the second cylinder volume, and a control valve for regulates rate of fluid flow through the flow channel. A filter is positioned across the flow channel upstream of the control valve relative to flow of fluid through the flow channel from the first cylinder volume to the second cylinder volume. The filter presents a filter area greater than the cross-sectional area of the flow channel to incoming flow to the filter and presents a filter area substantially equal to the cross-sectional area of the flow channel to outgoing flow from the filter.
Abstract:
The invention relates to a hinge comprising a moveable hinge section and a hinge section consisting of a fixed stop section, which are interconnected by at least one joint axis, and comprising a damping device mounted on one of the hinge sections whose translationally or rotatably moveable damping member is acted upon at least in the closure region of the hinge via gear means from the other hinge section. According to the invention for adjustment of the moveable damping member depending on the tilt of the moveable hinge section relative to the at least one joint axis, there is provided at least three moveable gear members are provided, of which one is the damping member itself.
Abstract:
Furniture hinge with damping and/or braking device in alternative to those already existing and capable of guaranteeing an improved efficiency during the closing and/or opening operation of doors, or other furniture parts, without any variations to the overall dimensions of standard hinges. The improved efficiency of the hinge is obtained by increasing the friction surfaces with a viscous medium present in suitable areas of the hinge and/or by allowing regulation of the trend of the angular velocities of one or more circular shaped elements, for example a disc, which act as braking elements in contact with the viscous medium.
Abstract:
A device, for automatic extraction of a supply drawer (e.g. a detergent drawer) from an electric household appliance, includes a releasable locking device for releasably locking the drawer; elastic means for pushing the drawer into an extracted position; braking means for opposing movement of the drawer; a support housing the elastic means and the braking means; and a toothed pinion fitted idly to the support, which is designed to leave at least one given circumferential portion of the teeth of the pinion exposed; the elastic means are designed to exert a torque in a given direction on the pinion, which is connected angularly integral with the braking means; the support and the releasable locking device are so designed that the exposed circumferential portion of the pinion teeth meshes selectively with a straight or curved rack, formed externally on a bottom or end wall of the drawer, by simply rotating the support with respect to the drawer, so that the same device can be used for both slide-out and swing-out drawers.
Abstract:
A door closer includes an anchor assembly for mounting on a door frame, an actuator assembly for mounting within the thickness of a door which is hinged for movement between open and closed positions, an operating member coupled by a linkage to the anchor assembly and mounted for a range of movements between a retracted position and an extended position, a resilient driving apparatus arranged to exert a driving force on the operating member, a damper mechanism operatively connected to the operating member so as to damp movement of the operating member at least in a direction towards the retracted position, and a resilient thrust device arranged to exert an increased driving force on the operating member over a defined part of its range of movement as the operating member approaches the retracted position.
Abstract:
A cover opening and closing device switches a cover body to rotate between a closed position and an open position. The cover opening and closing device includes a single operation button for switching the cover body between the closed position and the open position, a forcing device for forcing the cover body at least toward the closed position from a near closed position when the cover body is closed, and a switching device for releasing the cover body in the open position and allowing the cover body to rotate toward the closed position when the operation button is pushed.
Abstract:
A cover opening and closing mechanism switches a cover body on a corresponding surface of a main body between a closed position for closing the corresponding surface and an open position for opening the same. The cover opening and closing mechanism includes a forcing device for always urging the cover body toward the closed position; a push button; a switching device having a cam facing the button, an acceleration gear engaging a gear part provided on the cover body, and a striker; and a latch device for locking the striker in the open position of the cover body and releasing the lock when the button is pushed. The switching device switches the cover body from the closed position to the open position against a force of the forcing device.
