摘要:
The invention relates to a leaf support comprising a support device, to which a retaining element and a wall retaining element are adjustably attached. The support device comprises a hollow-profile section that encompasses a compartment for a sliding element, the external contour of said element comprising one or more sliding surfaces, which lie against the internal wall of the hollow-profile section. The support device comprises a spring. The sliding element can be displaced in the hollow-profile section in opposition to the elastic force of said spring. To improve the function and ease of use of a propping support of this type, the workpiece measurement tolerances of the sliding element are proportioned in such a way that the sliding surfaces of the sliding element are oversized in relation to the internal wall of the hollow-profile section, when lying against said wall.

The invention relates to a lock comprising a bar (50) which can be moved between an opening position and a closing position by means of a closing element (40) actuated by an actuating element (30). A stop piece (22) is associated with the actuating element (30) and blocks the actuating element (30) in the closing position. Said stop piece (22) can also be moved back and forth between a blocking position and an unblocking position, the actuating element (30) being released in the unblocking position. In order to ensure improved protection against vandalism using said lock, the closing element is coupled to the actuating element (30) in a rotationally fixed manner by means of an overload protection device (34), and the overload protection device releases the rotationally fixed connection between the actuating element (30) and the closing element (40) when a pre-determined or pre-determinable load is exceeded.
