Abstract: A camming coupler for removably attaching a music desk or other object to an upright support leg. The camming coupler includes an inner sleeve for receiving the upright support leg. The inner sleeve has at least one longitudinal slit formed therein, and preferably has four substantially equidistant longitudinal slits. The inner sleeve also has a cammed exterior surface. An attachment member extends from the inner sleeve, and is attachable to the music desk or other object. The camming coupler further includes an outer sleeve positioned over the inner sleeve. The outer sleeve has a cammed interior surface that corresponds with the cammed exterior surface of the inner sleeve. In use, the camming coupler is secured to a music desk or other object. An upright support leg is inserted in the inner sleeve, and the outer sleeve is rotated to compress the inner sleeve.

Abstract: An accessory mount for removably securing an accessory to an extendable shaft, such as a music stand shaft The extendable shaft includes a stationary shaft and a telescoping shaft. The accessory mount includes a sleeve with a longitudinal opening, the sleeve being receivable on the extendable shaft. A collar provided proximate the upper edge of the interior surface of the sleeve supports the accessory mount on the stationary shaft of the extendable shaft, and prevents the accessory mount from sliding down the extendable shaft. An accessory attachment point on the sleeve is adapted to receive a variety of accessories. The accessories can include string instrument holders, mute holders, accessory trays and the like, which can be interchangeably mountable on the sleeve. The accessory mount is quickly and easily installed on an extendable shaft, and can be installed without tools or adjustments.

Abstract: A camming coupler for removably attaching a music desk to an upright support of a music stand is disclosed. The camming coupler includes an inner sleeve for receiving the upright support. The inner sleeve has at least one longitudinal slit formed therein, and preferably has four substantially equidistant longitudinal slits. The inner sleeve also has a cammed exterior surface. An attachment member extends from the inner sleeve, and is pivotally attachable to the music desk. The camming coupler further includes an outer sleeve positioned over the inner sleeve. The outer sleeve has a cammed interior surface that corresponds with the cammed exterior surface of the inner sleeve. In use, the camming coupler is secured to a music desk. The upright support of a music stand is then inserted in the inner sleeve, and the outer sleeve is rotated to compress the inner sleeve.

Abstract: A music stand comprising a folding base having a clamp, a two-part vertical post, a music desk support attached to the two-part vertical post by a clamp, and a music desk attached to the music desk support.

Abstract: A shaft clutch mechanism, and method and apparatus for its production are disclosed. The shaft clutch mechanism has an upper body folded into a polygonal cross section with a plurality of fingers, each finger attached to and extending from a flat section of the upper body. The shaft clutch mechanism is pressed on to one end of an inner nested element of a telescoping body and is placed inside an outer element where the fingers are slightly deformed, providing slight friction sufficient to hold the inner element in place, but still allowing it to slide relative to the outer element. The method and apparatus for producing the shaft clutch mechanism use a two stage press and a bending device to take a continuous strip of material to form blanks which then are bent to form the shaft clutch mechanism that is pressed on to the inner element of the telescoping body.

Abstract: This invention comprises an apparatus for the safe temporary storage of a string instrument and a bow. The string instrument holder is attached to the desk of a music stand by means of an attachment clamp which can be adjusted to accommodate varying thicknesses of music stand desks. The string instrument is then hung by its scroll from two curved support members, The bow for a string instrument is hung by its flog from an additional curved support section extending from one of the curved support members holding the string instrument.
