Operating device for an electrically height-adjustable table, drive system and method for adjusting the height of a tabletop of the table
First Claim
1. An operating device for an electrically height-adjustable table having at least one electrical drive for a height adjustment of a table top of the table, and a controller coupled to the drive for controlling the drive, the operating device comprisingan actuating element to be arranged in the region of the tabletop;
- a force sensor that is designed to measure a force acting on the tabletop; and
an evaluation circuit that is coupled to the force sensor and that is designed;
to detect an actuation of the actuating element while the height adjustment of the tabletop is blocked, in particular, mechanically blocked;
to receive measurement values from the force sensor in a predetermined period of time after the detected actuation;
to determine a force alteration value from the received measurement values; and
if the force alteration value is greater than a threshold value, to output a control signal to the controller, the signal initiating the height adjustment of the tabletop in a direction that depends on a sign of the force alteration.

Abstract
An operating device is proposed for an electrically height-adjustable table having at least one electrical drive (EA) for adjusting the height of a table top (TP) of the table, and a controller (CTRL) for controlling the drive (EA). The operating device has an actuating element (BE, EMS, CS) to be arranged in the region of the table top (TP), a force sensor (FS), which is designed to measure a force acting on the table top (TP), and an evaluation circuit (EV). This circuit is designed to detect an actuation of the actuating element (BE, EMS, CS) during a height adjustment of the table top (TP), to receive measurement values from the force sensor (FS) within a predetermined period of time after the detected actuation, to determine a force alteration value from the received measurement values, and if the force alteration value is greater than a threshold value, to issue a control signal to the controller (CTRL) in order to initiate a height adjustment of the tabletop (TP) in a direction, depending on a sign of the force alteration value.

14. A method for adjusting the height of a table top of a table having an actuating element arranged in the region of the tabletop, and a force sensor that is designed to measure a force acting on the tabletop, the method comprising:
-
detecting an actuation of the actuating element while a height adjustment of the tabletop is blocked, more particularly mechanically blocked; receiving measurement values from the force sensor in a predetermined period of time after the detected actuation; determining a force alteration value from the received measurement values; and if the force alteration value is greater than a threshold value, performing a height adjustment of the tabletop in a direction that depends on a sign of the force alteration value. - View Dependent Claims (15, 16, 17, 18, 19, 20)
