Eine Vorrichtung zur Steuerung einer Fahrzeugklappe, die ein sicheres Öffnen und Schließen der Heckklappe und gleichzeitig einen Einklemmschutz ermöglicht wird erfindungsgemäß dadurch geschaffen, dass die Sensoreinrichtung einen verschieblich vorgesehenen Mitnehmer aufweist, wobei der Mitnehmer mit der Fahrzeugklappe gekoppelt ist, und dass die Sensoreinrichtung eine Führung aufweist, wobei der Mitnehmer in der Führung geführt ist.
Abstract:
The invention relates to a device for opening and/or closing a wing of a door, window or similar. The inventive device has a more user-friendly moment curvature than conventional devices, due to a closing spring (8) which rests on a hydraulic piston (4) and on a separation piston (9). The hydraulic piston (4) which forms the boundary of a pressure chamber (13) has a smaller front surface (annular surface 12) than the separation piston (9), said separation piston (9) forming a moving boundary wall of a counter-reservoir (14). The pressure chamber (13) and counter reservoir (14) are interconnected by a hydraulic line (15). Just before closure is completed, the hydraulic line (15) is closed off by a piston edge (4b). At the same time, another piston edge (4b) opens up a connection between the pressure chamber and (13) and a pressureless chamber (10). This produces a device which initially requires a relatively high degree of opening force to open the wing but requires less opening force in the subsequent part of the opening operation.
Abstract:
A spiral balance device for sash windows has a pipe inside of which extends a spiral rod having a screw section. A lower end of the spiral rod extends through a slot in a coupling rotatably disposed inside the lower end of the pipe and projects from the lower end of the pipe. A torsion spring has an upper end fixed near the upper end of the pipe and a lower end fixed to the coupling. A fixing member is fixed within the upper end of the pipe, and an adjustment member rotatably disposed below the fixing member engages with the upper end of the spiral rod. A ratchet mechanism disposed between the fixing member and adjustment member allows rotation of the adjustment member in a direction of winding the torsion spring and prevents rotation of the adjustment member in a direction of unwinding the torsion spring.
Abstract:
A display case includes a housing partially surrounding a display space, a door pivotably coupled to the housing and cooperating with the housing to further enclose the display space, and a hinge assembly for pivotably coupling the door to the housing. The hinge assembly includes a biasing member applying a biasing force on the door and a gear drive for adjusting a pre-tension force on the biasing member.
Abstract:
The invention relates to a furniture hinge with a fastening portion and a hinge part connected thereto via a multi-axis articulated connection, wherein a spring preloads the hinge part directly or indirectly, at least in a subregion of the adjustment path of the hinge part, with respect to the fastening portion, and wherein the spring is mounted or can be mounted under tension between two spring bearings. In order, in such a furniture hinge, to achieve improved movement control and to make the required manual force for hinge opening or closing more even, provision is made according to the invention for the spring (76) to be adjusted in the region of its two spring bearings (74, 84.4) during the adjustment of the hinge part (20) from the opening into the closing position and/or during the adjustment from the closing into the opening position.
Abstract:
A device to apply a rotational force to a spring of a rollup or overhead garage door counterbalancing mechanism. The device has a rotatable driven member mounted in a housing. The housing and the driven member have slots with an open end adapted to receive the shaft of the overhead garage door counterbalancing mechanism. A coupling member is configured to mount to the driven member and connect the driven member to the winding cone of a garage door spring to apply rotational force to the spring. The housing with the driven member may be connected to the body of an existing power tool in place of the original tool head, or, the housing may be permanently combined with a motor and transmission to provide a special purpose tool.
Abstract:
The invention relates to an actuator for moving a flap of a furniture item, having a pivotally mounted actuating arm for moving the flap, a spring device for acting on the actuating arm having a pivoting moment in the opening direction, an adjustment device for adjusting the actuator, wherein the adjustment device comprises a gear mechanism having a pinion and a crown gear, the crown gear axis of which forms an angle, preferably a right angle, with the pinion axis, wherein the gear mechanism comprises a second pinion, which engages with the same crown gear as the first pinion.

Abstract:
A device that converts an existing power tool to apply a rotational force to a spring of a rollup or overhead door counterbalancing mechanism. The device has a rotatable driven member mounted in a casting that carries a power transmitting structure. The casting and the driven member have slots with an open end for accommodating the shaft of the counterbalancing mechanism. A removable novel coupling structure inserts into the driven member and connects the driven member to the winding cone of a spring so that rotation of the driven member will apply rotational force to the spring. The casting with the driven member is connected to the body of an existing power tool in place of the original tool head. A motor in the existing power tool body is connected to the power transmitting structure in the casting to rotate the driven member.
Abstract:
A door closer assembly is provided, including a valve regulating an amount of hydraulic fluid that flows through the valve. The amount of hydraulic fluid flowing through the valve controls a force generated by the door closer assembly on a door. A first sensor measures an angular position of the door, and a second sensor measures an angular position of the valve. The angular position of the valve determines the amount of hydraulic fluid flowing through the valve. A controller controls the adjustment of the valve based on the angular position of the door and the angular position of the valve.
