Patent Application
20050120864
The invention relates to musical instruments of the percussion type and more particularly involves a novel fastener for mounting a cymbal or similar device onto a drum or other suitable support.
The general arrangement for mounting a cymbal onto a drum or other suitable support includes a rod or post which terminates at its upper extremity in a reduced threaded end portion over which the cymbal is fitted and secured in place by a washer and wing nut or other suitable fastening and retaining means.
In a typical mounting arrangement, a washer-like rounded metal disc or cup is fitted against a small shoulder on the rod. A felt washer or pad rests on the cup. The rod is covered by a rubber or plastic sleeve. The central hole of the cymbal is fitted over the rod around the sleeve, and the cymbal rests above the felt pad, supported by the metal cup. A rubber or leather spacing washer is positioned over the rod above the cymbal, and a wing nut is screwed down against the spacing washer.
There are two basic seat cup designs. A concave-shaped metal washer provides a platform onto which a cymbal rests. Typically the metal washer is free floating that allows it to follow the tilt of the cymbal and allow the cymbal to “breathe.” However metal-to-metal contact between the washer and the threaded post often causes rattling that can be especially bothersome in the recording studio. To minimize rattling, the washer needs to be immobilized. This is accomplished by pushing the sleeve against the washer by tightening the wingnut.
In alternate seat cup design, a one-piece plastic washer with integrated sleeve is provided.
This alternate design is a molded nylon or plastic seat cup that combines the washer and sleeve into one unit. With no metal-to-metal contact, this type of seat cup is quieter than separate metal washers. However, this design is not free floating and can inhibit the motion of the cymbal and choke the sound of the cymbals that require freedom of motion, such as crash cymbals. See
Sometimes a musician may want to play a cymbal in a loose mode to produce a reverberating sound with the cymbal held freely and loosely by the fastener. Other times the musician may prefer to play the cymbal in a mute or choked mode to produce a muted sound with the cymbal tightly clamped by screwing the wing nut tightly to the stand.
The need exists for a novel cymbal seat cup that facilitates floating or fixed position depending on the drummer preference or application.
The invention is a one-piece reversible cymbal seat cup and fastener arrangement that uniquely combines the advantages of both the selective playing mode option of the standard arrangements and a greater convenience when compared to the seat cups disclosed in the prior art.
The invention comprises a reversible seat cup for mounting a cymbal or like instrument to a cymbal stand or other suitable support.
The reversible seat cup allows free floating or fixed positioning of the seat cup, depending on application. For applications where the cymbal needs to be rigidly held, such as China cymbals, and/or minimal stand noise is essential, such as symphonic performances or studio applications, the seat cup can be positioned with the convex side positioned downward and “locked” firmly to the threaded post. A rubber O-ring on the threaded post fits into a receptacle in the seat cup to provide secure attachment and silent action. For applications where the cymbal, such as crash cymbals, needs freedom of movement, the seat cup can be positioned with the convex side positioned upward. A cavity on the opposite side allows the seat cup to float on the rubber O-ring for optimal cymbal sound. The plastic-type material of the seat cup and the rubber O-ring provides silent action and freedom of motion.
Some of the many objects, features and advantages of the invention will become apparent from the detailed description of a preferred embodiment of the invention, set out by way of example, with reference to the accompanying drawings, in which:
The reversible seat cup 10 has a convex or dome-shaped side 12 and a flat side 14 with a central aperture 16 extending therebetween. The central aperture 16 is defined by a first enlarged open portion 17, a second central narrow portion 18 and a third open portion 19. The first 4 enlarged open portion 17 is defined by a sloping surface 17a and a flat bottom surface 17b. The third open portion has a single diameter which is larger than the diameter ‘D’ of the second central portion 18 but smaller than the diameter ‘d’ defined by the flat bottom surface 17b.
With reference to
For applications where the cymbal, such as crash cymbals, needs freedom of movement, the reversible seat cup 10 can be positioned with the convex side 12 positioned upward as shown in
From the foregoing, it is clear that the present invention provides a one-piece reversible cymbal seat cup that uniquely combines the advantages of both the selective playing mode option of the standard arrangements and a greater convenience over the seat cups disclosed in the prior art.
While the foregoing invention has been shown and described with reference to a preferred embodiment, it will be understood by those of skill in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
