CROSS REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims the benefit of U.S. Provisional Application No. 61/945,518 filed on Feb. 27, 2014. The above identified patent application is herein incorporated by reference in its entirety to provide continuity of disclosure. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to scaffolding devices and work stations. More specifically, the present invention relates to a vise tool that can support work pieces for a user and attach to a scaffolding assembly for stable use. 
         [0004]    Many construction projects involve the erection of scaffolding to support workers and equipment in an elevated position adjacent to a structure. Many activities can be conducted while supported by scaffolding, including constructing primary structure, applying finishing materials and façades to a building, installing windows, and installing piping or wiring. Workers traverse the scaffolding to a desired position and engage in their work activities from the elevated state, using tools and operating on equipment to install necessary items. 
         [0005]    Construction workers, boilermakers, electricians, and other repair professionals are often required to make several adjustments to equipment in cases where pipes or tubes need to be cut or grounded. The worker is thus often obliged to travel to the ground level in order to perform the adjustment, thus wasting time and energy. In some cases, a worker may attempt to make an adjustment using a saw in one hand and a piece of pipe or other item in the other hand. This can create a dangerous situation and a dangerous work environment in which the worker or bystanders can be injured. This method can also result in poor craftsmanship. 
         [0006]    The ability to make adjustments to material and equipment being installed while on the scaffolding is imperative to efficiency and productivity. Cutting material or otherwise adjusting equipment to be installed can quickly become cumbersome if the operation is conducted using tools on the ground surface. The present invention contemplates a tool that can provide assistance with material handling when making such adjustments. Specifically, the present invention contemplates a vise tool that is affixable to existing scaffolding, whereby the vise provides a worker with an additional support for a work piece being cut, bent, or otherwise adjusted. This allows the worker to use both hands on the tool and not focus on supporting the work piece while in an elevated position. 
         [0007]    More specifically, the present invention contemplates a vice tool that is adapted to clamp to a vertical member of a scaffolding assembly, and optionally secure to a specific scaffolding arrangement. A general clamp for a tubular scaffolding member is contemplated, as well as a specific connector suitable for use with “cuplock” scaffolding, as disclosed in U.S. Pat. No. 3,992,118 to Siegers. This type of scaffolding joint is commonly deployed in the field and employs an underside cup and a movable retaining element thereover that secures over several scaffolding members. The cup and the retaining element sandwich the scaffolding members between the element and the cup. It is contemplated that the present invention can be configured to be supported by a joint of this type, as well as generally from a scaffolding vertical post member. 
         [0008]    2. Description of the Prior Art 
         [0009]    Devices have been disclosed in the prior art that relate to tools affixable to scaffold towers. These include devices that have been patented and published in patent application publications. These devices generally relate to tools having different purposes and working elements than that of the present invention. The following is a list of devices deemed most relevant to the present disclosure, which are herein described for the purposes of highlighting and differentiating the unique aspects of the present invention, and further highlighting the drawbacks existing in the prior art. 
         [0010]    One such device in the art related to tools affixable to scaffold towers is U.S. Patent Publication No. 2012/0055839 to Moore. Moore discloses a tool tray that secures to railings of a scaffold tower, whereby the tray includes an open area and upstanding lips to support tools and supplies. The Moore device, while securing to a scaffolding tower, is adapted to secure to one or more horizontal scaffold members, and moreover provide a function significantly divergent from that of the present invention. 
         [0011]    Similar to Moore is U.S. Patent Publication No. 2006/0169537 to Enochs, which comprises a tool basket that is configured to engage upstanding scaffolding members. Sockets disposed within the basket accept therein the upper portion of a scaffolding member to secure the same to a scaffolding tower. As with Moore, the Enochs device is adapted to provide a tray or tool storage area, as opposed to a vice affixable to a scaffolding assembly. 
         [0012]    Another tool affixable to a scaffolding tower is U.S. Pat. No. 2,245,661 to Fieroh, which discloses a safety system for a ladder placed against the scaffolding tower. The device comprises a hook that secures a rung of an inclined ladder to the scaffolding. The device prevents the inclined ladder from moving once positioned against the scaffolding tower, preventing instability or movement thereof. Similar to the Moore and Enochs devices, the Fieroh device is a tool affixable to a scaffolding tower with diverging elements and purposes. 
         [0013]    While the device of the prior art include those that are affixable to a scaffolding tower, no devices are present for securing a vice to a scaffold and providing a workstation upon which a work piece can be supported without requiring the hands of the user. The tools of the prior art represent those having different purposes and structures. The present invention contemplates vice tool that is securable to a vertical member of a scaffolding tower, whereby the vice is statically supported and can be used as an “extra pair of hands” while a user manipulates or operates on a supported work piece. 
         [0014]    Overall, it is submitted that the present invention substantially diverges in design elements from the prior art, and consequently it is clear that there is a need in the art for an improvement to existing scaffold workstation devices. In this regard the instant invention substantially fulfills these needs. 
       SUMMARY OF THE INVENTION 
       [0015]    In view of the foregoing disadvantages inherent in the known types of tools affixable to scaffolding towers now present in the prior art, the present invention provides a new vice tool that can be utilized for providing convenience for the user when working on a scaffolding tower and supporting a work piece with a tool that attaches to the vertical portion of a scaffold. 
         [0016]    It is therefore an object of the present invention to provide a new and improved scaffold workstation tool that has all of the advantages of the prior art and none of the disadvantages. 
         [0017]    It is another object of the present invention to provide a scaffold workstation tool that is affixable to a vertical member of a scaffolding tower, providing a static and independently supported vice tool for a user to work on an article held by the vice. 
         [0018]    Another object of the present invention is to provide a scaffold workstation tool that affixes to a vertical member of a scaffolding tower using one or more contemplated attachment methods, whereby an independent clamp is utilized, or a more specific cup scaffolding support is employed to support the vice in a static condition from the scaffolding. 
         [0019]    Yet another object of the present invention is to provide a scaffold workstation tool that can support a work piece as a user engages the work piece with another tool and while using two hands to work on the work piece or hold another tool. 
         [0020]    Another object of the present invention is to provide a scaffold workstation tool that may be readily fabricated from materials that permit relative economy and are commensurate with durability. 
         [0021]    Other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0027]    Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the scaffold workstation tool of the present invention. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for providing hands-free support of a work piece from a scaffold tower vertical member. The figures are intended for representative purposes only and should not be considered to be limiting in any respect. 
         [0028]    Referring now to  FIG. 1 , there is shown a side view of the scaffold workstation tool of the present invention. The tool provides a hands-free support for a user to place a work piece in the tool and operate on the work piece without physically supporting the work piece at the same time. The tool is affixed to a vertical member of a scaffolding tower, thus providing an additional support for a user while in an elevated position and where otherwise a vice tool would not be available. 
         [0029]    The tool comprises a vice having a substantially horizontal and elongated support surface  12  upon which to support a work piece. Above the support surface  12  is a vice assembly  11  that supports a moveable jaw  16  using an arm member  13  and a threaded rod  16 . The support surface  12  comprises an elongated and potentially widened area upon which to place a work piece. To clamp the work piece to the support surface  12 , the user employs the vice assembly  11 , thereby clamping the work piece as the assembly is supported from a scaffold upstanding member. 
         [0030]    Attaching to and extending from the support surface  12  is an elongated member  30 . The elongated member extends from the support surface  12  and terminates at an attachment end. The attachment end is adapted to clamp to or be temporarily affixed to a vertical post of a scaffold tower. Once the attachment end is affixed to the scaffold tower, the user can clamp a work piece using the vice assembly  11  and handle other tools to operate on the work piece as needed. 
         [0031]    The vice assembly  11  includes an L-shaped, upstanding arm member  13  that extends upwards and over the support surface  12 . The lower end of the upstanding arm member secures to the support surface  12  and the upper end  14  thereof terminates above the support surface  12 . The upper end  14  comprises a threaded aperture through which the threaded rod  15  of the vice can be rotated through. As is known in the art of vices, the threaded rod  15  includes a lower end that terminates in a clamping jaw  16 , while the upper end  17  of the threaded rod  15  includes an outwardly extending handle portion  18 . Rotation of the rod  15  adjusts the separation between the jaw  16  and the support surface  12 , and thus the clamping pressure applied to a work piece therebetween. 
         [0032]    Referring now to  FIG. 2 , there is shown a view of the workstation tool of the present invention supporting a work piece  100 . Also shown is a view of one contemplated embodiment of the attachment end  32  of the present invention. In this embodiment, the attachment end comprises a base having a pair or more outwardly extending tabs  32 . The base is adapted to be pressed against a rounded scaffold member, while the tabs  32  are adapted to be secured against the upstanding scaffold member using a cup-lock attachment method. This method supports the tabs  32  and retains the base of the attachment end  32  against the upstanding scaffold member, allowing the elongated member  30  of the tool to be extended outward therefrom in a substantially horizontal condition. 
         [0033]    The elongated member  30  is comprised of the attachment end  32  at one end, and a distal end  31  at a second end. Above the elongated member  30  is the support surface  12 , over which the vice assembly  11  is located. Between the vice assembly  11  and the support surface  12 , a work piece  100  is clamped and statically supported as a user engages the work piece  100  (i.e. modifying the article, trimming, etc. with another tool). The work piece  100  is clamped by the vertically movable jaw member  16  of the vice, controlled by the threaded rod  15  and the user handle  18 . 
         [0034]    Referring now to  FIG. 3 , the cup-lock attachment scheme of the present tool is highlighted. Using a cup-lock attachment method, the tool is supported by the scaffolding structure and employs the same method of construction to affix the attachment end of the tool. The cup-lock attachment is one in which the vertical and horizontal members  50  of the scaffold tower are attached to one another using a cup  51  and a locking ring  53 . The cup  51  is a rounded member having a flat upper area and an open volume  51  within which to accept the tabs of a horizontal scaffold member. However, the cup  51  is used in this instance to support the lower tab  33  of the attachment end of the tool elongated member  30 . 
         [0035]    To secure the attachment end, the lower tab  33  is placed within the cup interior  52 , and the upper tab  33  is secured using the locking ring  53 . The locking ring  51  slides along the vertical scaffolding member  52  and is forced over the upper tab of the tool. The locking ring surrounds the tab and retains it against the scaffolding member  52 , while the cup  51  secures the lower end. The cup  51  prevents downward sliding, while the locking ring  53  reacts prying loads from the tool. Together, they secure the attachment end of the tool against the outer surface of the scaffold member  52  above the cup  51 . A pair of locking ring tabs  51  along the scaffold upstanding member  52  prevents the locking ring  53  from moving upwards, thereby locking the ring around the tool tabs and preventing separation thereof. 
         [0036]    Referring now to  FIG. 4 , there is shown an overhead view of an alternative attachment device disposed along the attachment end of the tool. In this embodiment, a locking clamp  40  is employed, whereby the clamp  40  surrounds and compresses the upstanding member  52  of the scaffolding. The clamp  40  includes a first hinged arm  41  and a second hinged arm  42 , wherebetween a latch is used to secure the arms together. The arms  41 ,  42  are arcuate members secured to the attachment end of the elongated member  30  via pin joints  43 . The arms secure around the scaffolding upstanding member  52  and the distal ends of the arms secure together using a tab  45  and latch arm  44 . The tab  45  engages a keep in the opposite arm, whereafter the latch arm  44  draws the tab  45  towards the opposite arm and draws the arms together. This embodiment provides an attachment for the tool that does not require a specific type of scaffolding to employ the tool. It is contemplated that any clamp know to those skilled in the art may be deployed at this end, falling within the scope of securing to the scaffold upstanding member and supporting the tool in a substantially horizontal state. 
         [0037]    Overall, the present invention provides welders, electricians, construction workers and the like with an area in which they can perform repairs and adjustments while remaining on a scaffolding structure. The invention allows individuals to perform duties without having to climb up and down scaffolding. The device minimizes the risks associated with construction workers performing dangerous work using their hands without an adequate work space and reduces the occurrence of one dropping heavy and dangerous materials. And moreover, the present invention helps to preserve time and energy by providing immediate access to necessary items. 
         [0038]    It is submitted that the instant invention has been shown and described in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
         [0039]    Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
