This invention relates to the class of music. Specifically, this invention relates to the sub-classes of instruments, drums, and supports.
Drums are the simplest, and most primitive, musical instruments. The drum is a percussive instrument, which produces sound by striking a membrane. The sound is propagated through a membrane, or drumhead, to the drum shell, which is designed to resonate when the membrane is struck. The drumhead is coupled to the drum shell through drum hoops, lugs, and lug or hoop holders. The energy created by striking the drum head is transferred into a wave in the drum shell, producing the distinctive drum sound, a tuned impulse.
While drums usually cannot play different pitches, they are usually tuned. The drum is tuned by tightening or loosening the drumhead by adjusting the lugs and drum hoops. The tighter the drumhead, the higher the pitch propagated by the drumhead.
Many drummers use a drum kit. Drum kits have several different drums, which can be individually tuned. A drum kit is often composed of various drums, such as a bass or kick drum, snare drums, and tom drums, as well as assorted cymbals and high-hats. When a drummer is drumming, there is substantial vibration throughout the drum kit. Additionally, the various drums can move or flex as they are struck, meaning that the drums, themselves, are vibrating and, therefore, moving. This is especially true of the tom and snare drums.
A drum mount or support is a sub-classification that includes many different methods of mounting the drum to legs or to other structural elements. The mounts used for drums often degrade the sound, because the drum is held too tightly, damping or attenuating the tuned impulse. Depending on how the drum mount is attached, and how it supports the drum, it can hinder the drum shell resonance, the drumhead, or both. Any drum mount or support that rigidly fixes itself to the drum, whether to the drum shell or the drum hoops, risks damping the sound. A very small number of mounts attach to lugs or lug holders. As currently implemented, these integrated mounting brackets and lugs are a bad idea, because they fail to properly isolate the tuning of the lug from the tuning of the drum mount. The lugs are supposed to be tuning the drum. By adding additional stiffness (force) to the lugs, a fixed drum will change the tuning of the drum. An integrated lug and drum mount is conceptually attractive, because such a device, if it did not adversely affect the tuning of the drum head, would be easier to install on the drum.
Other mounts attach to the top and/or bottom hoops of the drum shell. Still other supports attach to the drum shell. Rigidly attached supports, whether mounted to the shell or hoops, will damp the vibration of the drum, and may, ultimately, distort the sound through buzzing or rattling, if the support mount is not properly engineered and attached.
As a result, a new device is needed, integrating the lug and drum mount, without unduly affecting the tuning of the drum. The new integrated lug and mount should allow the drum shell to resonate freely. Such an integrated lug and mount needs to maintain the drum, in position, without, itself, generating objectionable sounds. The integrated lug and drum mount should be quickly and easily adjustable. It should also allow for quick set-up and break-down of a drum kit. An integrated lug and drum mount that has variable stiffness, and isolates the drum shell from the structural members supporting the drum would be ideal.
This summary is intended to disclose the present invention, an integrated lug and drum mount that does not unduly affect the tuning of the drumhead. The embodiments and descriptions are used to illustrate the invention and its utility, and are not intended to limit the invention or its use. The present invention, an integrated lug and drum mount, has three essential pieces: a lug, a fixed component, and a mounting component. Both the fixed component and the mounting component can, themselves, be composed of multiple individual pieces or sub-components. In the embodiment used to illustrate the invention, herein, the fixed component is a U-bracket and the mounting component is comprised of the following sub-components: a screw plate, a receiver hub, and a connecting member.
The U-bracket is a planar member bent into a “U,” creating three distinct regions: a fixed member, a curved portion, and a free member. The U-bracket has an inner surface and an outer surface. The U-bracket has two edges. The U-bracket has a planar member that connects to the drum shell, called a fixed member. The U-bracket has a planar member, called the free member, which connects with the mounting component(s). The fixed member, curved portion, and free member are continuous, molded from a single piece of plastic or stamped from a single piece of metal. The fixed member has an end, called the lug end, distal to the curved portion. The free member has an end, called the free end, distal to the curved portion. The curved portion connecting the free member to the fixed member allows the free member to move relative with the fixed member. The mounting components can be mounted substantially anywhere along the free member between the free end and the curved portion. The closer the mounting component(s) are mounted to the curved portion, the relatively stiffer the mounting system. The closer the mounting component(s) are mounted to the free end, the relatively less stiff the mounting system.
In the illustrated embodiment, the mounting component has a screw plate, a receiver hub, and a connecting member. The screw plate is a flat, planar member with two holes in it. The receiver hub has a front surface and a rear surface. The rear surface of the receiver hub is flat, and mates with the free member of the U-bracket. Running longitudinally down the front surface of the receiver hub is a channel. On each side of the channel is a raised plateau, centered on the long-axis of the front surface of the receiver hub. On each side of the channel are two holes. One hole on each side is centered on the raised plateau. On the left side of the receiver hub, the second hole is below the raised plateau. On the right side of the receiver hub, the second hole is above the raised plateau. The receiver hub is made from homogeneous material. The centroid of the receiver hub is roughly the geometric center of the receiver hub.
The connecting member has a substantially rectangular base, with a front surface and a rear surface. On the rear surface of the connecting member rectangular base, there is a channel parallel to the short sides of the rectangular surface that is centered on the rear surface. There are two holes through the connecting member, positioned on either side of the channel.
The receiver hub is connected to the U-bracket with two threaded fasteners. The threaded fasteners from the receiver hub pass through elongated slots in the U-bracket, fastening to the screw plate. The connecting member fastens to the receiver hub with two additional threaded fasteners. In one embodiment, the connecting member has a bolt fastener that mates with a threaded screw post through the receiver hub, and a wing nut that mates with a second threaded screw post through the receiver hub. In another embodiment, the connecting member has two bolt fasteners. A drum leg or support can be securely captured and retained between the connecting member and receiver hub. In one embodiment, the free member of the U-bracket has a hole and slot configuration comprised of just holes and the receiver hub is fixed to one of a plurality of positions. In another embodiment, the free member of the U-bracket has hole and slots configuration of just slots, and the receiver hub can be located anywhere along the length the free member. The relative position of the support, such as a drum leg, can be adjusted by moving the receiver hub along the length of the free member of the U-bracket. With the support relatively closer to the curved portion, the mounting will be relatively stiffer. With the support relatively closer to the free end of the free member, the mounting will relatively less stiff. In this way, the stiffness of the support mounting system can be easily adjusted. Additionally, the user can select the appropriate position for their particular style, adjusting the integrated lug and drum mount to get the preferred amount of stiffness.
The tension of the drumhead is controlled by a drum hoop and a plurality of threaded fasteners called tuning screws. The tuning screws extend through the drum hoop towards the center of the cylindrical drum shell. The tuning screws terminate in lugs that are connected to the drum shell. By tightening the tuning screws, the drumhead is made stiffer. By loosening the tuning screws, the drumhead is made less stiff. Traditionally, lugs are held onto the shell with threaded fasteners.
The integrated lug is composed of a retaining portion and a rectangular portion. The rectangular portion of the lug and the fixed member of the U-bracket are connected to the drum shell with threaded fasteners. The retaining portion of the integrated lug has a threaded hole to receive a tuning screw. As with all the other lugs, the tuning screw that inserts into the retaining portion of the integrated lug can be adjusted by tightening or loosening it, thereby adding or subtracting stiffness from the drum hoop and drumhead.
The integrated lug and drum mount components can be fabricated from stiff, environmentally durable materials such as poly(methyl-methacrylate) (“PMMA” or tradenames Plexiglass or Lucite®), polycarbonate (“PC” or tradename Lexan®), acrylonitrile butadiene styrene (“ABS”), polypropylene (“PP”), high-density polyethylene (“HDPE”), low-density polyethylene (“LDPE”), wood, zinc, steel, or aluminum. The integrated lug and drum mount components can be fabricated from steel, which can be punched or forged. The integrated lug and drum mount components can also be fabricated from appropriate polymers, using standard manufacturing processes, such as injection molding. In the first embodiment, the U-bracket is fabricated from spring steel, while the connecting member and receiver hub are cast from zinc.
The present invention is illustrated with 7 drawings on 7 sheets.
