BACKGROUND OF THE INVENTION  
       [0001]     The present invention relates to a utility stand. More particularly to a utility stand for users requiring a portable work/utility stand. The utility stand incorporates the basic equipment a musician, surveyor, artist, or any user that requires a complete platform for work, practice or performing into a single structure that is easily disassembled or collapsed for storage and transport between uses.  
         [0002]     Prior art includes examples of a Portable Workstation, U.S. Pat. No. 6,068,355, a Portable Music Stand, U.S. Pat. No. 6,264,161. Other Portable equipment used by musicians, surveyors, and artists among others include portable footrests, portable instrument support stands, and portable reference tables and portable microphone stands.  
         [0003]     While having some utility these separate components have several major drawbacks. First, as individual pieces of equipment they lack stability and are easily knocked over because of their small support bases. Because they are separate pieces they are cumbersome to transport and setup. Also, the separate pieces of equipment require a larger total floor area than a single integrated utility stand. This is because the separate pieces of equipment require an extended base around each piece of equipment to achieve stability. Moreover, these separate pieces of equipment duplicate functions of the individual pieces and therefore more parts are fabricated than necessary.  
         [0004]     Another problem with portable work stations and music stands is the lack of convenient storage for tools, reference material, sheet music, and accessories, e.g. tools, paint brushes, pencils, guitar strings, markers, tuning devices to name a few which a user may require for work, study, or practice.  
         [0005]     Another problem is the lack of comfortable seating that can be adjusted to the user needs and workstation level.  
         [0006]     Accordingly, it is an object of the present invention to provide a portable utility stand that combines the separate components into a single utility stand configured for specific or multiple applications. This invention is focused toward the musician, but can be tailored for aforementioned users.  
         [0007]     Another object is to minimize the number of components and complexity by combining functions of support, seating, and storage.  
         [0008]     Yet another object is to provide an improved process for collapsing and setting up the portable utility stand for transport or storage requiring fewer set up steps. Yet another object of this invention is to configure mating parts such that the assembly cannot be setup in a manner that makes it unsafe for use.  
         [0009]     Yet another object of this invention is to provide a compact portable stand that is more resistant to tipping over when jostled or bumped than the individual pieces of equipment it replaces  
         [0010]     Yet another object of this invention is to provide convenient sttge for the users reference material and accessories.  
         [0011]     Yet another object of this invention is to minimize the required floor area.  
         [0012]     Yet another object of this invention to provide for additional auxiliary equipment to be attached such as a microphone, instrument tuning device, artists easel, or an umbrella to name but a few.  
       BRIEF SUMMARY OF THE INVENTION  
       [0013]     To achieve these and other objects, there is provided a portable utility stand with a substantially horizontal base frame supporting universal mounting receptacles that accept a broad range of components thereby enabling the base frame to integrate components such as: 1. a seating/storage unit, 2. a sheet music support or work platform, 3. a microphone/ancillary equipment support, 3. a foot rest, 4. an instrument or tool rest and a reference table to name but a few into a single unit. This single unit requires less floor area than the total floor area required by the same separate components; but has a larger stabilizing floor footprint than each separate component. This larger footprint provides more resistance to being tippd over than the separate units provide and achieves this with fewer parts.  
         [0014]     The base with universal mounting receptacles allows right hand or left-hand users to set up the components, as they prefer. In addition, a user could use the same utility stand for multiple uses by using for example the artist&#39;s easel in place of the sheet music support platform.  
         [0015]     At one end of the base frame a vertically adjustable member supports a padded seating bench with backrest. The bench provides both seating and storage. The storage unit is substantially below the seat with shelves and drawers that allow easy access without getting up from the seating bench.  
         [0016]     At the other end of the base frame is a rotatable and telescoping post supporting a rotatable platform. The platform thus mounted is adjustable by the user to provide a comfortable viewing distance and angle.  
         [0017]     Also attached to the base frame and in close proximity to the seat is an adjustable foot support that can be raised or lowered vertically, shifted left or right horizontally, tilted up or down, and support either foot or both feet simultaneously.  
         [0018]     Also attached to the base frame is an instrument support. The instrument support is rotatable about the vertical support axis and the user may install it any of the universal mounts on the left, right or behind.  
         [0019]     Also, attached to the frame is a rotatable horizontal/table platform close to hand for easy access and storage of the user&#39;s accessories. As with all the components configured for this utility stand they can be mounted in any receptable.  
         [0020]     In a preferred embodiment the utility stand is comprised of a tubular structure which is collapsible to a configuration suitable for transport or storage.  
         [0021]     In conjunction with the portable stand, another aspect of the present invention is a process for stowing the stand, including: 
        a. a means for disconnecting/collapsing the seating bench storage unit.     b. a means for rotating the sheet music platform support to be substantially parallel with the base.     c. a means for disconnecting/collapsing the instrument support.     d. a means for removing/collapsing the accessory shelf.     e. a means for disconnecting/collapsing the auxiliary equipment supports.        
 
         [0027]     Thus, in accordance with the present invention, a stable portable utility stand that supports user requirements for comfortable seating, displaying sheet music or other work in progress, storing accessories and reference material, supporting auxiliary equipment such as a microphone and providing a reference table is easily collapsed and setup.
