Abstract: A stop for handlebars of two-wheeled vehicles is integrated into the control head bearing of the vehicle. It is formed by a first component installed in the control head bearing with a circular arc-shaped groove that is arranged coaxially to the rotational axis of the control head bearing and a stop element protruding into this groove. The stop element is arranged on a second component that can be moved relative to the first part. The stop at the lower control head bearing is arranged within the head tube. The circular arc-shaped groove is arranged in the base and open towards the lower bearing shell. The lower bearing shell comprises an open recess extending over its height to the lower rolling bearing, which receives a stop element. The stop element has a radial lug protruding into the circular groove of the base.

Abstract: A resonator body for musical drum instruments is formed by shaping and gluing together several superimposed material layers, particularly wood veneer layers or plywood layers. The resonator body has the shape of a hollow cylinder. Abutting edges of the individual material layers extend in the direction of the resonator body axis and the abutting edges of the individual material layers are offset relative to each other in circumferential direction of the hollow cylinder. In order to ensure that the abutting edges are permanently and securely held together, the abutting edges of at least the outer material layer, preferably of all material layers, have contours which are toothed and complementary relative to each other and inter-engage in circumferential direction of the hollow cylinder.
