Abstract:
A push-out style window assembly including window hardware for frictionally retaining an open position of the window under typical loading conditions. A push-out style window assembly generally includes a friction hinge assembly including a track, a sash arm, a support arm, and a friction arm. The friction arm can include an adjustable and/or detachable slide enabling adjustment of a frictional resistance between the friction slider and the support arm. Using the friction arm, frictional resistance is provided so as to provide control both during opening of the window and in retaining the position of an open window.
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:
In a damped closing mechanism for automatic shutting pull door, a door closing mechanism includes a screw wheel to store restoring force, a change over device and a brake gear to produce a damping effect is integrally combined and equipped on the frame of a moving door panel. The brake gear is to alleviate the actuating force and moving speed of the door panel provided by the screw wheel. The change over device is capable of changing the damping effect of the brake gear to generate nearby the closing position of the door so as to alleviate colliding speed and impulse of the moving door panel with the door post when shutting without affecting the pulling of the door panel before closing.
Abstract:
The invention relates to a component (10) with a retaining function, comprising at least one first element (16) and at least one second element (26) which are arranged movably with respect to each other, at least one magnetizable component (18) with residual properties, a magneto-rheological fluid (38) or magnetic powder which is located in the magnetic field of the at least one magnetizable component, when the latter is magnetized, and via which the two elements can be brought into operative connection, and a coil (20) which is arranged in such a manner that, when energized, it can generate a magnetic field sufficient to magnetize the at least one magnetizable component, wherein the coil and the at least one magnetizable component are arranged in such a manner that a first currentless or energized state can be generated, sufficient so as to maintain the operative connection, and a second currentless state can be generated, as a result of which the operative connection can be undone. The invention furthermore relates to a holding-open system with a component of this type and to a method for operating a component of this type and a holding-open system of this type.
Abstract:
A drive arrangement is provided for motorized pivotal movement of a vehicle door. The drive has a self-locking motor unit, a gear connected downstream of the motor unit for producing linear drive movement, and a clutch connected therebetween. The clutch can be moved into an engaged state in which the motor unit for nominal operation is engaged to the vehicle door. When the motor unit is turned off, manual movement of the vehicle door is blocked. The clutch can be moved into a released state in which the motor unit is separated from the vehicle door in terms of drive engineering. The clutch can be moved into the intermediate engaged state with reduced transmission moment and force so that the vehicle door is kept in its current position at any time by self-locking of the motor unit, but can be moved by manual actuation with a minimum actuation force.
Abstract:
A carrier for a window sash having an actuatable friction adjuster. The friction adjuster has a carrier interface that interacts with a mating friction adjuster interface of the carrier such that the actuation of the friction adjuster by rotating it within an oblong slot in the carrier causes the carrier interface to interact with the friction adjuster interface and forces a rear portion of the friction adjuster into progressively increasing frictional contact with an adjacent portion of a window frame sash channel.
Abstract:
In the present invention, the transverse cross-section shape of a lubricant oil groove of a frictional resin body is formed to have a V shape where a lubricant oil is pooled and an oil film necessary to the smooth rotation of a rotation metal shaft is readily and positively formed and it is possible to prevent a breakage of the frictional resin body.
Abstract:
In order to keep the braking moment in doors with a pivoting brake for the continuously progressive braking moment variation with different inclinations of the pivoting axis of the doors to the vertical within a determined range, rules given for calculating said braking moment, especially in relation to the braking moment thereof causing the door to be unintentionally closed and for an advantageous variation of said braking moment over a door pivoting angle.
Abstract:
A door-holding control system for a vehicle slide door includes a slide door moved for its opening and closing on and along a guide track of a vehicle body by a slide door Moving mechanism, a clutch mechanism for interruptively transmitting a mechanical power from a drive source to the slide door moving mechanism, movement detecting element for detecting a movement of the slide door, and a clutch control for controlling a power transmission maintenance force of the clutch mechanism. The door-holding control system in improved such that: the clutch control controls the power transmission maintenance force to a minimal value of force required for stopping and holding the slide door while monitoring an output signal of the movement detecting element, and when the power transmission maintenance force exceeds a predetermined value of force, the clutch control controls the power transmission maintenance force to a value of force required for opening and closing the slide door, whereby the slide door is driven for opening and closing by the mechanical power of the drive source.
Abstract:
An electronic device (10) has a foldable housing (11) including a base unit (12) and a cover unit (14). The cover unit is rotatably joined to the base unit by a hinge mechanism. Within cover unit is a frictional hinge mechanism including a cam member (30), a cam follower (32) and an o-ring (34). The cam member has an attachment post (38) connected to an attachment gear on base unit such that the cam member is fixed to the base unit. The cover unit rotates against noticeable friction produced by o-ring rubbing between cover unit and cam member while cover unit is at angles of rotation larger than a pre-set angle, and cover unit rotates against minimal friction at angles of rotation smaller than the pre-set angle. The friction allows cover unit to maintain a multiplicity of positions with respect to base unit within a preselected range of angles larger than pre-set angle.
