Abstract

A mobile music stand rack having forward and rear support frames, an upper longitudinal elongate guide section and a lower longitudinally extending support section. These are arranged so that the music stands that are loaded onto the rack are positioned along the longitudinal center line. The rack is supported by forward and rear centrally located swivel mounted wheels, and by two side wheels at the mid-location of the rack. This provides stability for the rack, while permitting it to be conventiently maneuvered.

Dependent claims

A mobile music stand storage rack arranged to support a plurality of music stands, each stand comprising an upper laterally extending panel section, a vertical support column, and a base having support means extending outwardly from a lower end of said support column, said storage rack having a front end, a rear end, and a forward to rear extending longitudinal center axis, said rack comprising:

a. a central longitudinally extending support/guide section, comprising;
i. an upper guide section comprising a pair of laterally spaced, parallel upper guide rods defining therebetween a substantially unobstructed passageway to receive an upper portion of support columns of the music stands, said passageway aligned along said longitudinal center axis, said upper guide rods each having an upwardly facing upper support surface to engage lower positioned edges of the panel sections of the music stands in a manner to constrain upper ends of the support columns to be centrally located along said longitudinal center axis
ii. a lower longitudinally extending lower support means providing an elongate upwardly facing lower support surface to engage a lower base surface portion of the base of each music stand;
b. a forward frame section connected to the upper guide rods and to the lower support means, said forward frame section presenting an unobstructed entry area leading into the passageway and having laterally spaced side support members defining a forward open area sufficiently wide to permit the base of each music stand to pass therethrough;
c. forward stop means connected to said forward frame section adjacent said lower support means for preventing the base of a forwardmost music stand from moving forwardly outward from a storage position in the rack;
d. a rear frame section connected to the upper guide rods and to said lower support means;
e. a pair of laterally spaced ground support wheels positioned at a central support location of said rack on opposite sides of the rack and constrained for rotation along horizontal transverse axes;
and
f. a forward swivel mounted ground engaging wheel mounted at the front of the rack and centered on said longitudinal axis, and a rear swivel mounted ground engaging wheel mounted at the rear of the rack and centered on said longitudinal axis,
whereby when the rack is loaded from the front to the rear of the rack with a plurality of music stands a center of collective mass of the music stands is constrained to be located along the longitudinal center axis of the rack near the central support location, and lateral loads produced by a turning force applied to the rack are reacted mainly into one or the other of the side wheels, thereby enhancing stability and turning maneuverability of the rack.
