How tightly the wing nut is tightened determines how freely it moves when hit. Some players like cymbals to move freely therefore they keep the wing nut loose. Others prefer their cymbals to be “firmer” thus they keep the wing nut tighter. Looser cymbals are able to resonate more freely than tighter cymbals therefore another use of the wing nut is to control the amount of resonance of the cymbal.

Abstract
Description
- 1. Field of the Invention
- The present invention relates generally to fastening devices, and, more particularly, the invention relates to adjustable nuts for use on threaded shafts such as those found on drum sets having cymbals.
- 2. Description of Related Art
- A drum set is a group of separate percussion instruments which often includes one or more cymbals. 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 threaded post. A felt washer or pad rests on the cup. The post is covered by a rubber or plastic sleeve. The central hole of the cymbal is fitted over the post around the sleeve, and the cymbal rests above the felt pad, supported by the metal cup. A felt washer or pad is positioned over the post above the cymbal, and a wing nut is screwed down against the spacing washer. This operation is then repeated for each cymbal.
FIG. 16 shows a conventional seat cup arrangement featuringmetal seat cup 1,separate sleeve 2, felt members 3 and wingnut 4 which are mounted to a threadedpost 5. The cymbal is disposed between the felt members 3. - With particular regard to the cymbal set, the aforementioned wing nut is tightened down over the felt washer to keep the cymbal from flying off the stand when hit. How tightly the wing nut is tightened determines how freely it moves when hit. Some players like cymbals to move freely therefore they keep the wing nut loose. Others prefer their cymbals to be “firmer” thus they keep the wing nut tighter. Looser cymbals are able to resonate more freely than tighter cymbals therefore another use of the wing nut is to control the amount of resonance of the cymbal.
- Another problem encountered in breaking down and reassembling drum sets is an amount of time the setting up and breaking down the drum set consumes. When performing before audiences, there are often two or more consecutive musical bands who perform in sequence. After a first band plays, the drum set must be disassembled and removed from the stage in order that the second band can then set up their drum set and begin playing. This is time consuming and interrupts a rhythm of the concert.
- Accordingly, the need exists for an adjustable nut which can be placed on a threaded shaft, and subsequently removed, easily and rapidly.
- The present invention is directed to a quick release nut assembly to overcome the aforementioned drawbacks inherent in the prior art.
- The invention provides an adjustable nut for use with a threaded shaft, where the adjustable nut comprises a main body having an axial passageway through which the threaded shaft is adapted to pass. A locking insert is fitted to the main body. First and second wing members are pivotally mounted to the main body adjacent the locking insert, whereby the wing members include respective cam surfaces acting on the locking insert toward the axial passageway. The cam surfaces are adapted to deflect an inner surface of the locking insert toward the threaded shaft. The assembly provides three different mounting arrangements. The first and second wing members are adapted to provide (1) a locking position where the main body is immovably locked to the threaded shaft, (2) an adjustment position where the first wing member is in the locking position and the second wing member is in an unlocking position to permit selective adjustment of the main body with respect to the threaded shaft, and (3) a sliding position where the first and second wing members are in an unlocking position to permit the main body to slide axially along the threaded member.
- The pivoting wing members lock and unlock the wingnut to a threaded post depending on the orientation of the wings. When the wings are open (unlocking position), the wingnut easily slides past the threads of a threaded post. The wingnut does not have to be spun like conventional wingnuts thus attachment and removal is quick and easy. When the wings are closed (locking position), an engagement means grips the wingnut firmly onto the threads of a threaded post. With one wing open and one wing closed, the wingnut is partially engaged onto the threads of a threaded post and can be rotated to adjust the tightness of the wingnut.
- These and other new and useful features of the present invention will become apparent with reference to the accompanying drawings.
