Description

(54) DRUMSTICK
(71) We, RIFF RITE, INC., a Corporation organized and existing under the laws of the State of Minnesota, United States of
America, of 6112 Westridge Boulevard,
Edina, State of Minnesota 55435, United
State of America, do hereby declare the invention, for which we pray that a patent may be granted to us. and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to drumsticks.
According to this invention there is provided a drumstick comprised of two elongate parts containing graphite fibers, each part having a longitudinal groove therein so that a longitudinal bore is formed within the drumstick handle when the two parts are secured together.
Even though various compositions have been resorted to in efforts to provide drumsticks having improved characteristics, wood still is the most commonly used material. In this regard, in spite of the fact that wooden drumsticks are vulnerable to warpage and splintering, drummers continue to prefer the feel of such sticks and also like the tonal qualities that they produce.
Attempts have been made to make various composite drumsticks, using metal and/or plastics. While warpage and splintering can be reduced. or even eliminated, the feel and tonal qualities are not comparable to the wooden drumsticks.
Therefore. many drummers are willing to put up with the inadequacies of wooden drumsticks because, in their opinion, the benefits outweigh the shotcomlngs. and this accounts, at least in our opinion, for the continued use of wooden drumsticks in spite of the foregoing inadequacies.
An object of the present invention is to provide a drumstick that will be lighter in weight. as well as stronger. than wooden drumsticks. In this regard, not only are lightweight materials contemplated, but the invention permits the employment of a hollow bore which extends throughout a major portion of the drumstick’s length.
With this construction, the likelihood of drummer fatigue is reduced and the drummer can perform better in that he can increase the number of riffs or rolls per unit of time, this being particularly advantageous when performing a drum solo.
A further object is to provide a drumstick that can be very simply and inexpensively fabricated. In this regard, it is planned that the drumstick be moulded in two parts or shells which are longitudinally secured together. More specifically, it is possible to injection mould each shell so that the two can be secured together by means of sonic welding.
With the construction described above, is possible to provide a drumstick that willi not warp or become distorted when exposed to various temperatures and changes in humidity.
In one form of our invention, two elongate parts are secured together to form the tip, neck and handle of a drumstick. The handle has a longitudinal bore therein formed by a longitudinal groove in each part. One of the parts has a tongue extending from the bore to the free end of the tip and the other part has a groove for receiving said tongue therein. The material forming the tip, neck and handle contains nylon, the nylon serving as a matrix for graphite fibres.
In the following description of an embodiment of the invention, reference will be made to the accompanying drawing in which:
Figure 1 is a side elevational view of our drumstick, portions thereof being in section in order to show to better advantage the internal construction of the drumstick;
Figure 2 is an enlarged sectional view taken in the direction of line 2-2 at two longitudinally spaced locations of Figure 1 for the purpose of depicting the tongue and groove relation employed in the opposite end regions of the drumstick;
Figure 3 is an enlarged sectional view taken in the direction of line 3-3 of Figure 1 for the purpose of showing the hollow bore cross section that extends throughout the major portion of the drumstick handle;;
Figure 4 is an enlarged sectional view taken in the direction of line 4-4 at the two longitudinally spaced locations where the bore configuration differs from that appearing in Figure 3;
Figure 5 is a slightly enlarged fragmentary view taken in the direction of line 5-5 of
Figure 1, the view being taken in the direction of one mating surface of the part or shell at the left in Figure 1, and
Figure 6 is a fragmentary view on the same scale as Figure 5 but with the view being taken in the direction of the mating surface of the other part or shell at the right in Figure 1.
Illustrating our invention is a drumstock designated generally by the reference numeral 10, the exterior having the same appearance as a wooden drumstick. Actual ly, it is comprised of two parts or shells 12 and 14 which can be fitted or mated with each other and sonically welded together as will be described with greater particularity hereinafter. Since the drumstick 10 is of conventional shape when the shells 12, 14 are assembled. it includes a handle 16, a striking tip 18 and a connecting neck 20.
The drumstick 10 has a generally hollow bore 22 (Figure 3) which extends throughout a substantial portion of the length of the drumstick handle 16; however. it will be seen from Figure 1 that the bore 22 terminates within the handle 16 in a spaced relation with respect to the neck 20 and the free end (the lower end as the drumstick is oriented in Figure 1) of the handle 16.
Although not discernible in the finished drumstick, a mating line 24 appears in
Figure 1. this line being where the faces of the two parts or shells 12, 14 are joined together. it being contemplated, as already mentioned, that sonic welding be employed.
Describing the part or shell 12 in detail, it will be noted that it is formed with a generally flat surface 26 (see Figure 5) and a longitudinal groove 28 having converging ends. the converging end appearing in Figure 5 having been given the reference numeral 30. As can best be seen from
Figures 3 and 4. although also visible in
Figure 5. ribs 32 and 34 extend along each side of the groove 28. Still further. at the two spaced locations indicated bv the directional lines 4-4 in Figure 1. are pins 36 which project beyond the plane of the ribs 32 and 34. One of these pins 36 appears in Figure 5 as well as being represented in the sectional view constituting Figure 4.
As far as the part or shell 14 is concerned.
it is intended to mate with the shell 12. More specifically, it has a generally flat surface 38 which confronts the surface 26 of the shell 12 to form the mating line 24. Coacting with the groove 28 in forming the hollow bore 22 is a groove 40. In order to accommodate the ribs 32, 34 the groove 40 has a recess 42 extending along one side for receiving the rib 32 and a recess 44 extending along its other side for receiving the rib 34. Additionally, there are two bosses 46 in alignment with the pins 36. each boss 46 containing a hole 48 into which a pin 36 extends. In this way, the pins 36 assure a precise and easy mating together of the parts or shells 12, 14.
Also assisting in maintaining the parts or shells 12, 14 in a mated relation are tongues 50 on the surface 26 of the shell 12, one tongue extending from the upper end 30 (at the juncture of the ribs 32, 34) of the groove 28 to the extreme end of the striking tip 18, as is belived evident from the upper directional line 2-2 of Figure 1 producing Figure 2 and as can be clearly seen in Figure 5, and the other tongue extending from the other end of the groove 28 to the lower or free end of the handle 16, as is believed evident from the lower directional line 2-2 Figure 1 also producing Figure 2. The two tongues 50 are received in grooves 52 correspondingly formed in the surface 38.Thus, one groove 52 extends from the upper end of the longitudinal groove 40 to the extreme upper end of the striking tip 18, and the other groove 52, as can be seen in Figure 6, extends from the lower end of the groove 40 (where the recesses 42, 44 come together) to the lower end or bottom of the handle 16.
The grooves 52 each have one sloping side wall (approximately 30 as will be perceived in Figure 2 where the lead line for reference numeral 52 terminates) so that the tongues 50, which have parallel side walls, can be readily received therein.
With the parts or shells 12, 14 configured as described above, the shells can be placed together in preparation for their permanent attachment through the agency of sonic welding. More specifically, the pins 36 on the shell 12 fit into the holes 48 of the bosses 46 on the shell 14. The tongues 50 and supplemental grooves 52 also contribute to a precise registration of the shells 12, 14 so that a smooth and continuous outer surface on the drumstick 10 results, the mating or weld line 24 (exaggeratively depicted in
Figures 2-4) disappearing in the final drumstick. Whereas the assembled and finished drumstick 10 has been pictured in Figure 1, it will be appreciated that the line 24 has been shown mainly to denote the initially separate and distinct parts or shells 12 and 14.
The composition of the drumstick 10 is also important. In this regard, the material constituting the drumstick 10 contains graphite or carbon fibers which have been given the reference numeral 54 and which are randomly oriented in a matrix 56 of nylon. More specifically, the graphite or carbon fibers 54 constitute approximately 30% of the volume of the material of which the drumstick 10 is composed, and the matrix 56 the remainder, that is approximately 70%. However, the composition is susceptible to some variation and it is planned that the graphite or carbon fibers fall within the range of from 25-35% of the volume of the material and that the nylon matrix 56, which constitutes the remainder, fall within the range of from 65-75%.
It has already been pointed out that the drumstick 10 is comprised of two parts or shells 12 and 14. Having described the configuration and having given the composition of the drumstick 10, it will now be appreciated that the two parts or shells 12, 14 lend themselves readily to being fabricated by injection molding. Once joined by sonic welding, the drumstick 10 is the same as a one-piece drumstick having the core or bore 22, a construction not otherwise achievable.
Once assembled and welded, the drumstick 10 becomes virtually indestructible and will, unless severely abused, last indefinitely. The lighter weight, immunity to warpage and excellent tone-producing qualities of our drumstick 10. these being in addition to its increased strength, make it an exceedingly attractive instrument.
