1. Field of the Invention
The present invention relates to a drum which is constructed as a percussion instrument and more particularly to a drum that has a wooden hoop that stretches the drumhead.
2. Prior Art
In this drum, a trunk main body 1 formed in a cylindrical shape from plywood, synthetic resin fibers, a light metal, etc. is used as the main body of the drum; and a drum head 2 made of natural leather, a synthetic resin film, etc. is disposed on one or both open ends of this trunk main body 1. In addition, a hoop(s) 3 which surrounds the outer circumference of the drumhead 2 is disposed on the drumhead 2. A plurality of lugs 4 (which are the head stretching and securing fixtures) are disposed on the outside surface of the trunk main body 1. The lug bolts 5 of the lugs 4 are tightened so that the drum head(s) 2 is stretched by the hoop(s) 3 with a uniform force.
In this drum, the drumhead 2 is typically struck with a tip end of a stick, and occasionally a “rim shot” is made in which the hoop 3 is struck with a middle portion of such a stick. When performing the rim shot, various types of playing are possible. In one playing method, a sharp high note is generated by striking only the hoop; and in another type of play, the hoop and the drum head are struck simultaneously.
In cases where the rim shot is played in a drum that uses a wooden hoop, a distinctive tone color that is not seen in the case of a metal hoop is obtained. On the other hand, however, there are problems in terms of durability. In other words, in the case of a wooden hoop, anchoring holes for the bolt heads of the lug bolts used to stretch the drum head(s) are formed in the hoop, and thus these areas of the hoop are thin in thickness. Consequently, when these portions are repeatedly struck by a stick, cracks referred to by the reference symbol G are generated as seen in
Accordingly, the present invention is to solve the problems encountered in conventional drums that use a wooden hoop.
The object of the present invention is to improve the durability of the wooden hoop so that cracks and damage can be avoided in the areas of the anchoring holes for the bolt heads of the lug bolts even if these areas are struck in the rim shot play.
The above object is accomplished by a unique structure for a drum in which the drum head that is installed on one or both open ends of a trunk main body, which is a drum main body, is tightened by lug bolts and stretched by a hoop; and in the present invention, reinforcing rings are installed in anchoring holes that are formed in the hoop for receiving the bolt heads of the lug bolts, thus reinforcing the hoop.
Preferred embodiments of the present invention, which is shown in
Fastening of the reinforcing rings 6 can be accomplished by applying an adhesive agent when the reinforcing rings 6 are fitted in the manufacturing process of the hoop 3. Moreover, the fastening of the reinforcing rings 6 to the anchoring holes 3a by fitting can be performed selectively in accordance with the areas where the rim shot play is performed.
As seen from the above, in the present invention, the anchoring holes in a wooden hoop for the bolt heads of the lug bolts are securely reinforces by the reinforcing rings 6; and thus, no cracks or damage would occur in the hoop even if the hoop or the areas where the anchoring holes are formed are subjected to a strong hitting by the rim shot play. Accordingly, a drummer is not subjected to any psychological effect regarding damage to the drum, etc.; and damage to the external appearance of the drum over time can be avoided.
