DRUM

Abstract

The invention relates to a drum having a drum shell which forms an upper and a lower part (1, 2), is divided by a system ring (3) and is covered on each of the two open cover sides by a respective drumhead (4) which is tensioned down on the drum by a respective tension hoop (5) which is fastened to the drum by way of tuning screws (6), wherein the tension hoops (5) are tensioned against the common system ring (3) by way of their respective tuning screws (6) with interposition of the upper and lower parts (1, 2) respectively. In order to create advantageous construction conditions, it is proposed that the drum shell consists at least in sections of stone material and that the upper and lower parts (1, 2) of the two-part drum shell are bonded to the system ring (3) via stone silicone as an adhesive.

Claims

1. A drum comprising: a drum shell that forms an upper and a lower part, that is divided by a system ring and is covered on each of the two open cover sides by a respective drumhead each of which is tensioned down on the drum by a respective tension hoop that is fastened to the drum via tuning screws; wherein the tension hoops are each tensioned against the system ring via the respective tuning screws thereof with the upper and lower parts interposed respectively; and wherein the drum shell includes sections of stone material; and wherein the upper and lower parts of the two-part drum shell are bonded to the system ring by stone silicone as an adhesive.

2. The drum according to claim 1, wherein the drum shell is surface-smoothed on an inside drum jacket of the drum shell.

3. The drum according to claim 1, wherein the upper part or the lower part of the drum shell is formed in tubular drum shell sections that are glued together at ends thereof by an adhesive.

4. The drum according to claim 3, wherein the adhesive is a synthetic resin.

5. The drum according to claim 1, wherein a tensioning device tensions a snare carpet disposed in the drum on the tension hoop.

6. The drum according to claim 2, wherein the upper part or the lower part of the drum shell is formed in tubular drum shell sections that are glued together at ends thereof by an adhesive.

7. The drum according to claim 6, wherein the adhesive is a synthetic resin.

8. The drum according to claim 2, wherein a tensioning device tensions a snare carpet disposed in the drum on the tension hoop.

9. The drum according to claim 3, wherein a tensioning device tensions a snare carpet disposed in the drum on the tension hoop.

10. The drum according to claim 4, wherein a tensioning device tensions a snare carpet disposed in the drum on the tension hoop.

11. The drum according to claim 5, wherein a tensioning device tensions a snare carpet disposed in the drum on the tension hoop.

12. The drum according to claim 6, wherein a tensioning device tensions a snare carpet disposed in the drum on the tension hoop.

13. The drum according to claim 7, wherein a tensioning device tensions a snare carpet disposed in the drum on the tension hoop.

Description

BRIEF DESCRIPTION OF THE INVENTION

[0015] In the drawing, the subject matter of the invention is shown by way of example, wherein:

[0016] FIG. 1 shows a side view of the drum according to the invention and

[0017] FIG. 2 shows a partially broken up detailed view of FIG. 1 on a larger scale.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] A drum according to the invention has a drum shell formed by an upper part 1 and a lower part 2. The upper part 1 is separated from the lower part 2 by a system ring 3, as can be seen in particular from FIG. 1. The system ring 3 thus divides the drum shell, which is at least partly made of stone material. The tubular drum shell is covered on each of its two open sides by a drumhead 4, which is clamped to the drum by a tension hoop 5. The forces acting on the drumheads 4 from the tension hoops 5 can be adjusted by tuning screws 6. In contrast to the previously known prior art, however, these tuning screws 6 do not engage directly on the drum shell, but on the system ring 3, which divides the drum shell into an upper part 1 and a lower part 2, either directly or via connecting components known per se. As a result, the tension introduced by the tuning screws 6 is not introduced into the drum shell, which would lead to a distortion of the desired sound characteristics, but is derived from the system ring 3, which is made of, for example, aircraft aluminum. Each tension hoop 5 has its own set of tuning screws 6. A particularly non-destructive tensioning of the drumheads 4 is achieved when the tuning screws 6 of the set of the tension hoop 5 assigned to the upper part 1 are staggered with the tuning screws 6 of the set of the tension hoop 5 assigned to the lower part 2 and engage on the opposite sides of the common system ring 3.

[0019] For a secure fit of the upper part 1 and lower part 2 on the system ring 3, an adhesive is provided which is applied between upper part 1 and system ring 3 and lower part 2 and system ring 3. It has been found that stone silicone is particularly suitable as an adhesive with regard to an undisturbed sound quality of the drum.

[0020] A particularly clear sound experience is achieved if the inner surface 7 of the drum shell, i.e. the inside drum jacket of the drum shell, is smoothed. This can be done, for example, by polishing or satin finishing.

[0021] As shown in particular in FIG. 2, the upper part 1, but in an alternative embodiment also the lower part 2, may be formed in several parts. In this exemplary embodiment, the upper part 1 comprises two tubular or annular drum shell sections 8 which are bonded together by a synthetic resin.

[0022] FIG. 2 illustrates a possible design of the tuning screws 6, which can be attached to the system ring 3 via a threaded sleeve 9 and another screw 10.
