8. The percussion instrument according claim 1, wherein the resonance body comprises at least one storage space.

9. The percussion instrument according to claim 8, wherein the storage space comprises a drawer.

10. The percussion instrument according to claim 8, wherein the storage space is closed with a lid.

11. The percussion instrument according to claim 5, wherein at least one fastening element is attached to the support structure.

12. The percussion instrument according to claim 11, wherein the percussion instrument can be fastened to a frame by the fastening element.

13. The percussion instrument according to claim 11, wherein at least one bracket is attached to the fastening element.

14. The percussion instrument according to claim 13, wherein the bracket is foldable.

15. The percussion instrument according to claim 13, wherein the bracket is generally U-shaped, comprising two parallel legs having upper ends pivotally supported by the fasting elements and lower ends connected to one another by a lower bracket bar, wherein the percussion instrument comprises an outwardly protruding connection point, and wherein the percussion instruments can be connected to an identical percussion instrument by the bracket in that the lower bracket bar snaps onto the outwardly protruding connection point of the identical percussion instrument.

16. The percussion instrument according to claim 13, wherein the percussion instrument can be stacked on top of like percussion instruments by the bracket.

17. The percussion instrument according to claim 1, wherein the resonance body comprises a plurality of compartments, each comprising at least one resonance chamber, at least one associated cover plate and at least one associated tone bar.

18. A percussion instrument, comprising: a plurality a tone bars; retaining elements for fastening the tone bars; a resonance body with an upper side and a lower side made of plastic or another material which can be stamped, injection-molded or cast, the resonance body comprising a plurality of resonance chambers, each of the plurality of resonance chambers having an opening being directed towards an associated on of the plurality of tone bars; and a cover plate which bounds the resonance chambers on a side facing the tone bars, the cover plate having a plurality of sound holes, wherein the tone bars are fastened to the cover plate by the retaining elements, and wherein the cover plate circumferentially abuts a circumferential edge of the resonance body and is thereby connected to the upper side of the resonance body in a positive-locking manner.

DETAILED DESCRIPTION

(6) The invention is described in detail below with reference to the figures mentioned in the form of embodiments. In all figures, the same technical elements are marked with the same reference signs.

(7) FIG. 1 shows an exemplary percussion instrument 1. This percussion instrument has 13 tone bars 11. A bracket 18 and a closed lid 162 are also shown.

(8) FIG. 2 shows the percussion instrument 1 of FIG. 1, disassembled into its main components. Between the tone bars 11 and the cover plate 14, there are two retaining elements 12, which connect the tone bars 11 with the cover plate 14. The cover plate 14 has sound holes 141 in the cover plate 14, which are arranged above the resonance chambers 131 belonging to the tone bars 11. Furthermore, fourteen mounting points 142 are arranged in two rows in the cover plate 14. At these mounting points 142, the retaining element 12 is fastened to the cover plate 14. The resonance chamber 13 with resonance chambers 131 and a lid 162 belonging to the resonance chamber 13 is below the cover plate 14. The resonance body 13 is shown in detail in FIG. 3. The resonance body 13 is located in a support structure 15 that encloses the resonance body 13 on three sides. On the lower side of the support structure 15, four fastening elements 17 are attached, wherein two fastening elements 17 hold one bracket 18 each.

(9) FIG. 3 shows the resonance body 13 with separate resonance chambers 131. The volume and position of the resonance chambers 131 are adapted to the tone bars 11. The resonance body 13 has a circumferential edge 134 on the upper side 136, which allows the cover plate 14 to be positioned relative to the resonance body 13 in a positive-locking manner.

(10) FIG. 4 shows a side view of the percussion instrument 1, wherein two brackets 18 are attached to the support structure 15 by fastening elements 17. One bracket 18 is sketched in a folded-out position. In that position, the bracket 18 can be used as a stand. The second bracket 18 is shown in a folded-in position. As an example, possible angles with dashes are shown, with which the bracket 18 can snap into the fastening element 17. Folding the bracket 18 by 180° from its folded-in position enables a connection to an adjacent percussion instrument. In the folded-in position, the bracket 18 lies flat and does not project beyond the fastening elements 17. This means that the percussion instrument 1 can be placed on the fastening element 17 without the bracket 18 being in contact with an installation surface. Furthermore, it is possible, without dismantling the bracket 18, to fix the percussion instrument 1 on a frame with a bracket 18 in such position.

(11) FIG. 5 shows two percussion instruments 1 stacked on top of each other. By means of a bracket 18, which can be fastened at a suitable angle, two or more percussion instruments 1 can be stacked on top of each other. Additional connection points 135 are attached to the outer side of the percussion instrument 1. The bracket 18 of the upper percussion instrument 1 can be fastened or snapped onto these.
