  • Patent number: 10774552
    Abstract: A support is provided, comprising a first bar with a first abutment element, a second bar with a second abutment element, and a guiding device by which the first bar is displaceably guided on the second bar. An actuating device which acts on the first bar and which comprises an actuating element is arranged on the second bar. A displacement of the first bar in a first direction of displacement can be initiated by actuation of the actuating element. The first direction of displacement is a direction of increase in distance between the first abutment element and the second abutment element. The actuating device comprises a blocking device which blocks a displacement of the first bar in relation to the second bar in a second direction of displacement, which is opposite the first direction of displacement, at least when no active releasing action occurs at the blocking device.
