Abstract

An electrical actuator system for adjustable furniture, in particular height-adjustable tables ( 1 ), comprising at least one linear actuator ( 4 ), at least one operating unit ( 22 ) and a control box ( 12 ). By arranging therein at least one connector for cables into mutually opposing wall sections of the control-box cabinet for connection of linear actuators with cables, great simplification of the connection of the linear actuators to the control box is achieved, as when an uncoupling has been omitted, when the actuators have been wrongly connected during assembly, or if an actuator falls apart.

First claim

The invention claimed is:

1. An electrical actuator system for adjustable furniture, comprising at least one linear actuator, at least one operating unit, a control box comprising a case-like cabinet having two mutually-opposing end walls, and wherein the control box contains a power supply and a controller for the at least one linear actuator, and wherein one end wall of the control box includes a mains voltage port for a mains voltage cable and at least two ports for connection of the at least one linear actuator, and for connection of the at least one operating unit, and wherein the electrical actuator system comprises one or more motor cables for connecting one or more linear actuators with one or more ports, and one or more control cables for connecting one or more operating units with one or more ports, and including at least one port for a cable in each of two mutually-opposing wall sections of the cabinet of the control box for connecting linear actuators.

2. The electrical actuator system according to claim 1 , wherein each of the cables includes a connector at each end.

3. The electrical actuator system according to claim 1 , wherein each actuator includes a cable which extends from an end of the motor housing, a free end of each cable including a connector.

4. The electrical actuator system according to claim 1 , wherein a motor housing of an actuator includes a port for a cable.

5. A control box for an electrical actuator system comprising a cabinet, a mains voltage port for supplying the control box with a mains voltage, one or more connectors for connection of one or more linear actuators and one or more ports, for connection of one or more operating units, and including at least one port in each of two mutually-opposing wall sections of the cabinet of the control box for the connection of linear actuators.

6. Electrically-adjustable furniture comprising an electrical actuator system according to claim 1 .

7. The electrically adjustable furniture according to claim 6 , wherein the electrically adjustable furniture comprises a height-adjustable table.

8. A control box for an electrical actuator system comprising:
a cabinet which includes first and second opposing walls,
a first exterior port located in one of said first and second walls for connection of a cable supplying a mains voltage,
a second port located in one of said first and second walls for connection of a cable from an operating unit, and
a third port located in said first wall and a fourth port located in said second wall for connection of respective cables from first and second linear actuators.

9. An electrical actuator system for adjustable furniture, said electrical actuator system comprising:
a first linear actuator,
a first operating unit,
a control box which includes a cabinet containing a power supply and a controller for said first linear actuator, said cabinet having opposing first and second end walls, a first exterior port located in one of said first and second end walls for connection of a mains voltage, a second exterior port located in one of said first and second end walls for connection of said first operating unit, and a third exterior port located in said first end wall for connection of said first linear actuator,
a first cable connecting said first linear actuator with said third exterior port, and
a second cable connecting said first operating unit with said second exterior port.

10. The electrical actuator system according to claim 9 , wherein said cabinet of said control box includes a fourth exterior port in said second end wall.

11. The electrical actuator system according to claim 10 , including a second linear actuator and a third cable for connecting said second linear actuator with said fourth exterior port.
