Description:
DYNAMIC DRUM BEATER

PRIORITY:

This application is a continuation in part and claims priority to US Nonprovisional Application number 15/256777 filed September 6, 2016.

BACKGROUND OF INVENTION:

The present invention is directed to a dynamic drum beater. Conventional bass drum beaters are inserted into bass drum pedals and used to strike the bass drum. Bass drum beaters have felt, wood or plastic beaters and chrome, steel metal shafts. The dynamic drum beater is based on a conventional beater; however, differs drastically because it utilizes a spring and damper arrangement to aid the performer in striking the drum resulting in a lift in rebound which enhances the upstroke. Capitalizing on the energy of a spring to aid the performer and rebound off of the drum. The end of the beater (where it impacts the drum) uses a conventional felt, wood or plastic tip or essentially any material used to strike drums.

The prior art discloses a drum stick with a spring coupling between the handle portion and the impacting portion. The spring can be locked so as to make the handle and impacting portion of the stick fixed. The prior art further discloses a ball fitted to a compression spring actuated be electric current for use with a Xylophone. Also disclosed in the prior art, is a thimble device which fits over the fingers of the player of a Glockenspiel, or similar instrument, where a small metal spring projects from the end of the thimble to which a wooden button is attached. The prior art also makes known the use of a spring loaded base drum assembly where the spring works to return the drum stick and head away from the drum face when the foot pedal is released.

The present invention differs from the prior art in one preferred embodiment of the present invention which employs a spring between the hinged portion of the beater shaft and the impact portion of the beater shaft with a damping cover means fitted over the spring to stiffen the assembly and provide the desired flexibility when used. In a second preferred embodiment of the present invention, a universal joint is employed between the hinged portion of the beater shaft and the impact portion of the beater shaft with a spring cover means fitted over the universal joint to stiffen the assembly and provide the desired flexibility when used. In yet a third preferred embodiment of the present invention, a ball and socket joint is employed with a spring cover means fitted over the ball and socket joint to stiffen the assembly and provide the desired flexibility when used. BRIEF SUMMARY OF INVENTION:

A dynamic drum beater comprising a shaft with a head portion and a base portion, the head portion of the shaft adapted to receive a drum striking attachment, the base portion of the shaft adapted to receive a pivotal attachment of an actuator mechanism, a flexible joint disposed between the head portion and base portion of the shaft to provide vibration of the drum striking attachment on the drum.

DETAILED DESCRIPTION OF INVENTION

The present invention will now be described in terms of the presently preferred embodiment thereof as illustrated in the drawings. Those of ordinary skill in the art will recognize that many obvious modifications may be made thereto without departing from the spirit or scope of the present invention.

The present invention is directed to address the short comings in an arrangement where a spring or other flexible joint is inserted between the fixed-end and the striking end of a drum stick. These arrangements provide the bounce back when the striking end of the drum stick comes in contact with the drum, but do not effectively control it. Specifically, the striking end of the drum stick -in the single spring configuration - bounces back in a non-linear and generally uncontrolled manner. This is especially true in the ball joint and universal joint embodiments when the outer elastic housing is not used.

One series of preferred embodiments of the present invention is directed to solve the uncontrolled and non-liner bounce back disclosed in the prior art by the use of an elastic sheath surrounding the joint in the drum stick. In this series of preferred embodiments, the elastic sheath surrounding the joint acts as a stiffener and damper (i.e., in the spring configuration); a stiffener, a spring and a damper (i.e., in the universal joint configuration) and a stiffener, a spring and a damper (i.e., in the ball joint configuration). An isometric view of one preferred embodiment of the present invention is shown at Fig 1. Figure 1 depicts a typical bass drum beater device. However, the device could easily be adapted - without departing from the spirit and intent of the present invention - for use in a drum stick to be held in the hand of the user.

In a preferred embodiment of the present invention, a spring 3 is disposed at the head of shaft 1. Fig 2. The base of the shaft 1 is used to fix the shaft to a foot pedal device (Fig 5). The drum beater device 4 could be any traditional beater device or material (e.g., felt, wood, composite, synthetic) typically used. The spring 3 is wrapped with an elastic sheath 2 to provide damping to the spring 3 and stiffness to the spring/elastic sheath assembly. Fig 2. The elastic sheath 2 is made from an elastic material such as rubber, synthetic rubber or polymer. The operator of a typical foot bass drum arrangement, would attach the base of shaft 1 to a foot pedal device (Fig 5) and use that device to actuate the present invention (Fig 1) and strike the bass drum with the drum beater device 4.

In another preferred embodiment of the present invention, a universal joint 5 is disposed at the head of shaft 1. Fig 3 and Fig 3 A. The base of the shaft 1 is used to fix the shaft to a foot pedal device (Fig 5). A drum beater device 4 is affixed to the head of the shaft 1. The universal joint 5 is wrapped with an elastic sheath 2 to provide spring and damping to the universal joint 5 and stiffness to the universal joint/elastic sheath assembly. Fig 3. The operator of a typical foot bass drum arrangement, would attach the base of shaft 1 to a foot pedal device (Fig 5) and use that device to actuate the present invention (Fig 1) and strike the bass drum with the drum beater device 4.

In yet another preferred embodiment of the present invention, a ball and socket joint 6 is disposed between the head and base of shaft 1. Fig 4 and Fig 4A. The base of the shaft 1 is used to fix the shaft to a foot pedal device (Fig 5). A drum beater device 4 is affixed to the head of shaft 1. The universal joint 6 is wrapped with an elastic sheath 2 to provide spring and damping to the ball and socket joint 6 and stiffness to the ball and socket elastic sheath assembly. Fig 4. The operator of a typical foot bass drum arrangement, would attach the base end of shaft 1 to a foot pedal device (Fig 5) and use that device to actuate the present invention (Fig 1) and strike the bass drum with the drum beater device 4.

A second series of preferred embodiments of the present invention is directed to solve the uncontrolled and non-liner bounce back disclosed in the prior art by the use of an elastomeric flexible coupling material (Fig 5, Fig 5A and Fig 8) and, alternatively, a thermoplastic polyurethane material (Fig 7, Fig 7A and Fig 9) - each placed in between the two ends of a drum stick. In this series of preferred embodiments, an elastomeric flexible coupling 7 is used like that manufactured by Dynaflex® in place of a spring wrapped in a rubber sheath to provide both vibration and damping. Fig 5 and Fig 5 A. Alternatively, a thermoplastic polyurethane material 8 like that produced by NINJAFLEX is used in place of a spring wrapped in a rubber sheath to provide both vibration and damping. Fig 7 and Fig 7A.

The elastomeric flexible coupling 7 like that manufactured by Dynaflex® bore size is matched to the drum stick 1 shaft diameter. Set screws through the outer bores of the elastomeric flexible coupling work to connect the drum stick shafts to the coupling. Fig 5 and Fig 5 A.

The thermoplastic polyurethane material 8 like that produced by NINJAFLEX is manufactured to create a transition element between two drum stick shafts 1 and 3 with internal bores sized to match the drum stick shafts diameter. Fig 7 and Fig 7A. Glue is used to connect the drum stick shafts 1 and 3 to the transition element. In use, the operator of the foot pedal device would depress the pedal and thereby swing the drum beater device 4 of the present invention (Fig 2, Fig 3, Fig 4, Fig 5 Fig 7 A) hinged at the base of the shaft 1 into contact with a bass drum. Fig 6 Fig 8 and Fig 9. At the moment of impact of the drum beater device 4 on the bass drum, the flexible joint arrangement of the present invention (Fig 2, Fig 3, Fig 4, Fig 5 and Fig 7 A) will provide an instantaneous rebound of the drum beater device 4 on the bass drum. The present invention utilizes the various flexible joint configurations of the present invention to achieve a more robust rebound which allows the musician to achieve an upstroke off of the bass drum with greater ease thereof reducing fatigue and the effort required to achieve down and upstrokes is much less than compared to conventional drum beater arrangement.

Without departing from the spirit and intent of the present invention, any of the above preferred embodiments could be adapted for use with hand held drum sticks. Further, the placement of the spring (3), universal joint (5), ball and socket joint (6), an elastomeric flexible coupling (7) and/or a thermoplastic polyurethane element (8) along the shaft 1 relative to the location of the drum beater device will provide more or less bounce of the drum beater device 4 against the bass drum. Specifically, on the hand held drum stick, optimal performance of the flexible joint is obtained when the flexible joint is located between 25% to 75% of the shaft length as measured from the tip of the drum stick. Here, again, the present invention allows the user to achieve a more natural rebound which allows the operator to achieve an upstroke off of the drum with greater ease.

Those of ordinary skill in the art will recognize that the embodiments just described merely illustrate the principals of the present invention. Many obvious modifications may be made thereto without departing from the spirit or scope of the invention as set forth in the appended claims.
