Abstract: A building element 1 consists of several individual layers 2, 3, 4 and is designed as a honeycomb construction with partial hollow bodies 26, 27 protruding over the basic construction 16. Surfaces 10, 11 of adjoining individual layers 2, 3, 4 together form a wall of a small thickness. Individual surfaces 10, 11 of the individual layers 2, 3, 4 have a pre-stressing for improving the connection with adjoining surfaces.

Abstract: A construction element 1 consists of multiple individual layers 2, 3, 4 whereas the medium layer 3 is in turn composed of a multitude of additional individual layers 23, 24, 25. The individual layers 2, 4, 23, 24, 25 are configured in such a way that they interlock and clamp into each other thereby producing or defining surfaces that allow the elements or individual layers 2, 4, 23, 24, 25 that are integrated in the construction of the construction element to evenly absorb the forces that are being applied. At the same time, not only pressure or lateral forces but also tensile and transverse forces can be absorbed so that altogether a construction element 1 with a low weight but high stability has been created. This construction element 1 can be shaped or deformed appropriately and can also be extended three-dimensionally so that an adaptation to the individual conditions in any plane or direction is possible.

Abstract: Percussions instruments, especially drums, consist of a ring-shaped hollow form covered with hide or a resonant skin on the top and bottom. The skins are arranged in such a way that they can vibrate freely. To do this, a flexible tensioning device is used, whereby the tension of said skins can be adjusted by the percussionist during play. A tubular body integrated into the edge of the support in the form of a closed ring-shaped body is thus provided. Said body can be moved towards or away from the hollow form or the outer wall thereof. The tubular ring rests against the percussive ring on the U-shaped supporting edge like a stop and acts upon the edge of the skin. When the periphery of the tubular hose is modified, the described movement and tensioning of the skin occurs.

Abstract: The inventive cymbal arrangement is used as an instrument (1), especially as a rhythm instrument or accompanying instrument, and comprises several cymbals (2, 3, 4) of graduated diameters. A wide range of options is provided by using different types of cymbals (2, 3, 4) which are struck against each other or played with drumsticks or brushes. The instrument (1) can also be described as a triple hi-hat. It can be mechanically or pneumatically controlled. By enabling different shapes of cymbals (2, 3, 4) to be used, the sound range of the inventive instrument is substantially increased.

Abstract: A hi-hat (1) is used as an instrument, especially as a percussion instrument. The inventive hi-hat consists of a set of in total three or more cymbals (2, 3, 4). An upper mobile cymbal (2) and a lower, also mobile cymbal (4) are struck against the middle, stationary cymbal (4) by means of a common operating device (5), in order to produce a noise. The movement of the pedal (31) is reversed by means of either an appropriate pneumatic arrangement with a piston (8) and corresponding cylinder chambers (10, 23) or a mechanical device which diverts the pedal movement via a cable (50) and a deflection pulley (51) so that the outer tube (14) moves upwards against the middle cymbal (3) whilst the rod (7) is pulled downwards in the opposite direction, hereby causing the upper cymbal (2) to strike the middle cymbal (3).

Abstract: A hi-hat 1 has available an operating unit 1 with the aid of which the upper cymbal dish 2 as well as the lower cymbal dish 4 can be moved. The upper cymbal dish 2 is for this reason allocated to a rod 7 which can, as is well known, be moved downward in relation to the lower cymbal dish 4 through the foot pedal 12. At the same time, the motion of the foot pedal 12 is guided through a cable line 13 and a guide pulley 14 such that a sheath tube 10 which bears the lower cymbal dish 4, is moved in the reversed direction, that is here upward, through appropriate connections. cylindrical springs 24, 25 and further safeties guarantee that overloading of the parts cannot occur.
