ABSTRACT:
BACKGROUND OF THE INVENTION
a) Technical Field of the Invention
The present invention relates to an elastic mounting device for a tom-tom drum holder, and in particular, to screw rods mounted externally with elastic collars for mounting to positioning holes provided on the counterhoop of the drum.
b) Description of the Prior Art
FIG. 5
shows a conventional mounting structure for a tom-tom drum holder
30
. The holder
30
is provided with holes
31
at the four comers thereof for the mounting of screw rods
32
with the counterhoop body
33
of the drum. A screw nut
35
provided at the inner surface of the counterhoop
33
is locked with the holder
30
. In this conventional mounting device, there is no any component to provide vibration effect of the drum caused by sound resonance when the drum is beaten. Some manufactures modify the four screw rods
32
by mounting a pad
34
to the bottom section of the holder
30
(as shown in
FIGS. 6-8
) and in combination with two vertical end plates to mount the screw rod
32
to the counterhoop body
33
. This modification is to provide elasticity to the drum such that the drum will appropriately vibrate, i.e., to provide resonance effect and the quality of sound produced by beating of drum becomes excellent. These conventional structures make use of screw rods to directly mount the holder
30
to the counterhoop
33
. However, when the drum is beaten, the tightness of the drum mounted to the holder will become loose, and the sound quality of the sound produced by the drum is affected. In particular, when the screw rods
32
are made from metallic material. If the mounting device is made of wood, gap may be formed at the connection of the metallic material and the wood material. Thus, the mounting of the holder has to be adjusted again. In practice, as the pad
34
is thin, he pad
34
loses its elasticity after some time of use. Thus, the function of the pad
34
, in this case, is very limited.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an elastic mounting device for a tom-tom drum holder comprising a counterhoop body connected to the batter head of the drum and a holder for supporting the drum, characterized in that the holder is mounted aerially and two ends of the holder are provided with holes for the insertion of screw rods for tightening, the screw rods are externally mounted with an elastic collar and the screw rods with the elastic collar are then inserted into positioning holes provided on the counterhoop body, the inner edge of the counterhoop body is provided with a mounting pad and a fastening nut for securing together with the holder, thereby by means of the mounting of the elastic collar with the screw rods, the drum vibrates slightly in accordance with the beating of the batter head of the drum.
Yet another object of the present invention is to provide an elastic mounting device for a tom-tom drum holder, wherein the tightness of the holder with the tom-tom drum can be adjusted so as to provide appropriate vibration effect of the drum when the batter head of the drum is beaten.
Another object of the present invention is to provide an elastic mounting device for a tom-tom drum holder, wherein the tightening of the holder will not damage the counterhoop of the drum.
A further object of the present invention is to provide an elastic mounting device for a tom-tom drum holder, wherein the beating of the batter head can produce excellent sound.
The foregoing objects and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts. Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
