Abstract:
An actuating drive for moving a flap of an item of furniture, including: an actuating arm pivotally mounted about a pivoting axis for moving the flap, a spring device for applying a force onto the actuating arm, a transmission mechanism for transmitting a force of the spring device onto the actuating arm in a closing direction and for transmitting a force of the spring device onto the actuating arm, and an adjusting device for adjusting a position of an actuating portion of the actuating drive in or along a guide. The actuating drive includes a coupling device coupling the spring device, the pivoting axis of the actuating arm, and the actuating portion to one another. By adjusting the actuating portion in or along the guide, the position of the dead-center of the actuating arm and the force of the spring device acting towards the opening direction can be variably adjusted.

Abstract:
The invention relates to a furniture drive (4) for ejecting a moveable furniture part (3) from a closed end position relative to the body of the item of furniture (2), comprising; a housing (9), an electric drive unit (10) which is arranged in or on the housing (9), an ejection lever (12) which can be driven by the electric drive unit (10) for transferring a movement to the moveable furniture part (3). The ejection lever (12) is mounted so that it can rotate about a rotational axis (11) on one side and comprises a free lever end (13) on the other side. Said ejection lever (12) comprises an ejection surface (14) between the rotational axis (11) and the free lever end (13). Said ejection surface (14) of the ejection lever (12) comprises, at least in sections, a toothing (15).
Abstract:
A counterbalance mechanism including: a housing having a first aligned pair of through holes and a second aligned pair of through holes; a pivot nose having a third aligned pair of through holes, a fourth aligned pair of through holes and an aligned pair of arcuate slots; an energy storage device having first and second spring mounts and at least one spring, the first spring mount having at least one first flange and a pivot flange having a fifth through hole, the second spring mount having at least one second flange and a sixth through hole and the at least one spring includes first and second ends, the first end is secured to the at least one first flange and the second end is secured to the at least one second flange; a first pivot pin disposed in the first aligned pair of through holes and the third aligned pair of through holes; a stop member disposed in the second aligned pair of through holes and the aligned pair of arcuate slots; a second pivot pin disposed in the fourth aligned pair of through holes and the fifth through hole; a force magnitude adjuster arranged to control a force of the at least one spring; and, a force angle adjuster arranged to control a force direction of the at least one spring.
Abstract:
A piece of furniture has an actuating arrangement for a flap of the piece of furniture. An actuating arm arrangement includes a lever arrangement for moving the flap and a main spring that acts in the closing direction (SR) to hold the flap closed. The piece of furniture also has an ejecting device for ejecting the flap in the opening direction (OR) by overpressing the flap in the closing direction (SR). At least one support spring acts in the opening direction (OR) and is separate from the ejecting device, and supports the ejecting motion of the ejecting device. At least in an overpressed closed position (US), the spring forces (A, U) are together greater than the closing force (Z) which acts on the flap and which is provided by the main spring acting in the closing direction (SR).
Abstract:
A system having an adjustable pivot length assist mechanism for a cover or door of an enclosure. Adjusting lengths of a link may change a differential ratio of mechanical advantage in that a small change in the force transfer link length yields a large change in the gas spring load for a given force at the other end of the link. The mechanism may utilize one or more gas springs. One end of a spring may be connected to a bellcrank rotatable on a shaft attached to a portion of a hinge secured to the enclosure. Another portion of the hinge may be attached to and support the door relative to the enclosure. Attached to another location on the bellcrank may be a force transfer link connected to a lever attached to a door portion of the hinge. The force transfer link may have a length adjustment. At least one end of each of the one or more gas springs may have two-dimensional movement.
Abstract:
The invention relates to a sliding door device including: a slider mounted to the sliding door so as to be movable on the rail; a lever provided in the slider so that a middle part thereof would be rotatable; a first roller provided on one end side of the lever so as to be rotatable on the rail; a recess formed in the rail so that the first roller would fall thereinto before the sliding door reaches a completely closed position, the recess having a rising wall surface of the rail being in a direction intersecting with a rotating surface of the first roller, the rising wall surface capable of coming into contact with the first roller; and a cable mounted to the sliding door for driving the sliding door to a closing direction when the cable is pulled. The cable is connected to the other end side of the lever and causes the lever to rotate in a direction that the first roller pushes the rail when the cable is pulled.

Abstract:
Drive device for a flap of a piece of furniture, having at least one actuating arm which is, or can be, activated by a spring device and is intended for moving the flap, and having a pushing-out device, via which the flap can be moved from the closed position, in the direction of the open position, over a first opening-angle range (M1), wherein the spring device exerts substantially no force on the flap in the first opening-angle range (M1), and the spring device moves the flap in the opening direction only in a second opening-angle range (M2), wherein the second opening-angle range (M2) adjoins the first opening-angle range (M1) or, at most, slightly overlaps the same.
