Furniture item, and adjustment mechanism for a furniture item
First Claim
1. A furniture item, comprising:
- a fixed first structure;
a second structure;
a drive assembly for moving the second structure in relation to the first structure between predefined target positions, said drive assembly having at least two servo drives; and
an adjustment mechanism for maintaining the second structure in desired alignment with the first structure, said adjustment mechanism including a control unit for controlling operation of the servo drives, and first and second signal transducer assemblies operatively connected to the control unit, with the first signal transducer assembly interacting with one of the servo drives and with the second signal transducer assembly interacting with the other one of the servo drives such that a movement to any one of the target positions by the second structure in relation to the first structure is accompanied by a simultaneous activation of the first and second signal transducer assemblies, and a deviation from a target position causes the control unit to manipulate operation of one of the servo drives to adjust the movement of the second structure.

Abstract
A furniture item includes a fixed first structure, a second structure, and a drive assembly for moving the second structure in relation to the first structure between predefined target positions. The drive assembly has at least two servo drives. An adjustment mechanism is provided for maintaining the second structure in desired alignment with the first structure and includes a control unit for controlling operation of the servo drives, and first and second signal transducer assemblies which are operatively connected to the control unit, wherein one signal transducer assembly interacts with one servo drive, and the other signal transducer assembly interacts with the other servo drives. So long as a movement to any one of the target positions by the second structure in relation to the first structure is accompanied by a simultaneous activation of the first and second signal transducers assemblies, the second structure is in proper alignment to the first structure. When the second structure deviates from the target position, the control unit manipulates operation of one of the servo drives to adjust the movement of the second structure.

11. A method of maintaining a movable structure in proper alignment with a fixed structure of a furniture item, comprising the step of causing a shutdown or at least a slow down of a faster one of two drive units when only one of two signal transducers is activated in response to a movement of the movable structure to a predefined target position.
