Abstract

Electrical operating unit comprising a first and a second part, where the two parts can be mutually adjusted. The Operating unit ( 1 ) comprises a first part constructed as a housing ( 2 ), which contains the electric equipment with at least one electric switch and a second part constructed as a mounting unit ( 3 ) for the first part. The two parts are interconnected about a shaft ( 17 ), or pivot, so they can rotate mutually. When the operating unit is mounted the housing ( 2 ) will assume a first position, an initial position. By pressing the housing ( 2 ) it rotates about the shaft ( 17 ) and is brought into a second position, an activation position, where the switch(es) is/are activated in that they are pressed against the second part ( 3 ). With this embodiment of the operating unit the piece of furniture can be adjusted in either direction by pressing the housing ( 2 ). The housing ( 2 ), besides from functioning as a switch, can also be equipped with other switches and displays.

First claim

What is claimed is:

1. An electrical operating unit comprising:
a housing, the housing comprising an upper part and a lower part;
a mounting unit mounted into a recess formed in one of the upper part or lower part of the housing, the mounting unit being connected to the housing, with the housing being configured to rotate about an axis with respect to the mounting unit; and
at least one electrical switch,
wherein the housing and the mounting unit can be mutually adjusted, and wherein the housing can assume a first position, an initial position, from which the housing by rotation about the axis can be brought to a second position, an activation position, where the switch is activated.

2. The electrical operating unit according to claim 1 wherein the side of the mounting unit which faces towards or protrudes into the housing, is furnished with a pin for activation of the at least one electrical switch.

3. The electrical operating unit according to claim 1 , further comprising at least one spring element, the spring element configured to impact the housing with a spring force when the housing is brought into the activation position, and rotate the housing back into the initial position, when the housing is no longer being impacted into the activation position.

4. The electrical operating unit according to claim 3 , wherein the at least one electrical switch is a dome switch, where the dome in the switch is used as the spring element.

5. The electrical operating unit according to claim 4 , wherein there are two dome switches arranged such that they are located on opposite sides of the rotation axis of the housing.

6. The electrical operating unit according to claim 5 , wherein the two dome switches are located on two diametrically opposite corners of a printed circuit board disposed in the housing, and the mounting unit comprises two pins located across from the two dome switches when the mounting unit is mounted in the recess of the housing.

7. The electrical operating unit according to claim 1 , wherein the mounting unit is mounted in the recess in the housing such that it protrudes a distance over the top side of the housing.

8. The electrical operating unit according to claim 7 , wherein the recess is surrounded by a round-going side wall and the mounting unit also protrudes a distance over the round-going side wall.

9. The electrical operating unit according to claim 1 , wherein the recess of the upper part or the lower part of the housing is slightly larger than the mounting element in a direction perpendicular to the rotation axis of the housing, but only so large that the edges of the recess still function as mechanical stops for the mounting unit when the housing rotates about the axis.

10. The electrical operating unit according to claim 1 , wherein a frontmost portion of the housing constitutes an angle with the remaining part of the housing such that this frontmost portion faces away from the surface on which the operating unit is mounted.

11. An actuator system comprising at least one lifting column or actuator driven by an electric motor, and a control unit connected to the lifting column or the actuator driven by the electric motor wherein the actuator system comprises an electrical operating unit according to claim 1 connected to the control unit, and where the lifting column or the actuator driven by an electric motor can be activated through the electrical operating unit.

12. A height-adjustable table comprising an actuator system according to claim 11 .

13. The height-adjustable table according to claim 12 , further comprising a tabletop and where the electrical operation unit is mounted on an underside of the tabletop at an edge thereof.
