It allows a workpiece to be moved laterally from a fully retracted position, where the workpiece is out of the way of someone getting out of or into his or her seat, to a working position, where the workpiece is suspended at a preferred location and orientation before the operator. It is designed to be operated from the left side or right side of a chair, easy chair, stool, couch, or other type of seating means.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The claimed invention relates to a utility workstation for positioning various types of workpieces, and especially for positioning workpieces requiring adjustable vertical and/or horizontal rotation. The claimed invention further relates to a utility workstation employing display, storage, and local light and magnifier means.




2. Description of the Prior Art




The claimed invention is a utility workstation, which is herein defined as an adaptable workpiece positioning device for presenting a suspended workpiece before an operator. The claimed invention permits employing local light and magnifier sources and auxiliary components designed to facilitate the work process; auxiliary components being holders, supports, trays, storage units, and the like.




The work desk is a very familiar example of the basic workstation. We typically place the everyday things that we use to do our work either in, on, or about our desk, while we use the top of our desk to display and negotiate our work. We do this to maintain organization in our work affairs and to minimize our having to get up from our desk to find and use the basic tools and materials of our work. So it is with the utility workstation concept as applied in this document. Auxiliary components provide means for displaying and storing the tools and aids for the work to be performed and the positioning device provides means for displaying and negotiating the work itself.




How one might use the claimed invention is a function of the requirements of the work to be performed in much the same way that the nature of our work principally determines what we put in and on our desk; there are numerous applications which could be claimed for it. For example, the claimed invention is particularly useful for arts and crafts pursuits in that (1) it allows a hobbyist or artist to work while sitting, (2) it provides for an assortment of specialty holders and supports, (3) it allows an object or material to be presented in a variety of positions, (4) it provides local light and magnifier sources, and (5) it provides for various types of trays and containers for tools and supplies.




The claimed invention is a free-standing workpiece positioner that easily accommodates various seating means as it allows the workpiece to be swiveled away from the working position and out of the way of an operator leaving or entering his or her seat. The swivel action of the claimed invention is not found in the prior art.




Several U.S. patents include design aspects recognizable in the claimed invention under examination in this application. These include: Nolting, U.S. Pat. No. 1,432,725; Webb, U.S. Pat. No. 4,145,006; Dubbs et al., U.S. Pat. No. 4,771,980; and Adams, Jr., U.S. Pat. No. 5,141,211. Adams, Jr. is nearest in approximating some of the design concepts of the claimed invention but even it does not anticipate the swivel action of the claimed invention or its integration of auxiliary components into its overall structure as integral parts of the device rather than as add-on extras.




The ability to swivel the workpiece into and away from the working position and to match the auxiliary requirements for accomplishing a task with the basic and adaptive features of the claimed invention results in an exceptional tool for task-specific and general purpose utilization not present in the related prior art.




SUMMARY OF THE INVENTION




The overall object of the claimed invention is to provide a typically seated operator with means for positioning a suspended workpiece as needed, wherein the operator is allowed unencumbered access to a seating means by permitting the workpiece to be moved from a retracted position, where the workpiece is out of the entry and exit path, to a working position, where the workpiece is at a preferred location and orientation for working. The claimed invention includes local light and magnifier sources as well as means for incorporating auxiliary components that provide display and storage options for tools and supplies.




Therefore, one principal object of the claimed invention is to provide a versatile means for positioning a suspended workpiece, permitting that workpiece to be raised, lowered, and rotated horizontally and/or vertically.




Another principal object of the claimed invention is to permit a workpiece to be laterally moved fully into or away from a working position.




Another principal object of the claimed invention is to provide light and magnifier sources.




Another principal object of the claimed invention is to provide for auxiliary components such as holders, supports, trays, and containers as would be useful for a given application.




Another principal object of the claimed invention is to provide a base system that can be configured for operation of the claimed invention from the left side or right side.

. These openings


102


are arranged so as to properly orient the leg members for left side or right side use. Auxiliary components can be mounted directly onto the plate member


93


or, absent leg members, the plate member


93


can be mounted directly onto a floor or other type support surface.





FIG. 11

presents a detailed view of the scroll frame


69


shown earlier in FIG.


6


& FIG.


7


. The scroll frame


69


consists of two lockbars


103


, two scroll rods


104


, and two sidebars


105


, and is used to scroll fabric or other material. One end of a piece of fabric or the like is laid over a slot


106


in the scroll rod


104


such that it extends slightly beyond the slot


106


. A lockbar


103


is placed over the fabric, and pressed down into the slot


106


, carrying the fabric along with it. This operation is repeated for the other end of the material using the remaining scroll rod


104


and lockbar


103


.




The sidebar


105


is made up of two half-sections


107


held in alignment by bolts


108


that pass through first openings


109


in the half-sections


107


and terminate in threaded knobs


110


. Second openings


111


receive the ends of the scroll rods


104


, and third openings


112


allow the scroll frame


69


to be mounted onto the holding assembly


11


as shown in FIG.


6


& FIG.


7


. The openings for the scroll rods


104


and the holding assembly


11


are arcs in each of the half-sections


107


that form circular openings because one half-section


107


is inverted with respect to the other. First arcs


113


in the second openings


111


are of a radius such that the two half-sections


107


form an opening having a diameter approximately that of the scroll rods


410


. However, the depth of the first arcs


113


is such that a small gap


114


exists between the half-sections


107


that permit a clamping action to be exerted on the scroll rods when the threaded knobs


110


are advanced on the alignment bolts


108


. Second arcs


115


of a radius slightly greater than that of the threaded studs


24


of the holding assembly


11


create third openings


112


in the sidebar


105


for easy mounting of the scroll frame


69


onto the holding assembly


11


.




The fabric, having been secured in the scroll rods


104


by the lockbars


103


, is now scrolled on the scroll rods


104


until the distance between the two rods is approximately that of the space between the second openings


111


. The ends of the scroll rods


104


are inserted into the second openings


111


of the sidebars


105


, and one of the scroll rods


104


is clamped in place by advancing either the upper pair of threaded knobs


110


or the lower pair. The fabric is further wrapped around the unclamped scroll rod


104


until the fabric is taut. Once taut, the unclamped rod is then clamped in place. The scroll frame


69


is mounted onto the holding assembly


11


, which in turn is mounted onto the headblock assembly


12


. The fabric is scrolled up or down on the scroll frame


69


by loosening the threaded knobs


110


, scrolling the fabric up or down, and retightening the threaded knobs


110


.
