RELATED APPLICATIONS 
       [0001]    The present application claims priority of U.S. Provisional Application Ser. Nos. 60/928,137 and 60/928,142, both filed May 8, 2007, the entire disclosures of which are hereby incorporated by reference. 
     
    
     TECHNICAL FIELD OF THE INVENTION 
       [0002]    The present device relates to tool storage units. Particularly, the present device relates to a tool storage unit having integrated power to several locations, including a compartment for storing rechargeable tools and their corresponding charging units. 
       BACKGROUND OF THE INVENTION 
       [0003]    Tool storage units have been traditionally used not only for storage of various hand and power tools, but also for securing such tools in a manner which prevents theft and/or misuse by an unauthorized user. Locking drawers, doors and roll tops on tool storage cabinets have typically been used to provide such security. 
         [0004]    With the quickly growing market of cordless power tools (i.e., battery operated tools), storage units have begun to adapt by providing compartments specifically for these cordless devices and their battery charging units. However, stored cordless tools, particularly a battery for such tools after a previous day of use, can be at low power when removed from the cabinet the next day. Typically, the tool or battery has to be recharged for a period of time before beginning the ensuing day&#39;s use. Such charging time during work hours is time which might otherwise be spent using these tools for their intended purpose. Instead, the time is passed waiting for a proper charge to be achieved on the requisite batteries. 
         [0005]    Alternatively, the charging units, tools and/or batteries could be left to charge outside the security of the locked storage unit, but this leaves the expensive components susceptible to theft and misuse by others. This is an undesirable alternative for many users working with cordless power tools at unsecured work-sites. 
         [0006]    Another problem identified in prior art tool storage cabinets, is the availability of power. Not only have tool cabinets been traditionally used for storage of various hand and power tools, but they can also function as a work surface on which to perform various tasks involving such tools. Typically, the top surface of the storage unit is designed with various features to facilitate its use as a work surface, including for the support of, for example, diagnostic equipment. Pull out surfaces proximate to the top of the storage unit have also been provided in some designs where a smaller work surface is preferred. 
         [0007]    While the quickly growing market of cordless power tools, as noted above, has minimized the use of some corded power tools, it has not eliminated the need for a convenient power source at a typical work area. In fact, it could be argued, given the limited operating capacity of battery operated tools, the need for a convenient power source is now greater than ever. Cordless devices require a charged battery for operation and, therefore, battery charging units are needed close by for jobs lasting longer than the typical battery charge. This is equally true for computers and computerized diagnostic equipment, which may be capable of battery operation for a limited time as well. 
         [0008]    Further, some devices may just not be available or suitable in cordless form. Long extension cords and generators present additional problems when used in, for example, small work areas or the outdoors. Accordingly, for such devices a convenient power outlet is a must. 
         [0009]    The present device solves these and other problems associated with prior art devices by providing both a designated compartment within a storage unit which offers storage security and power charging ability, and a storage unit which offers a work surface and a convenient power source for cordless and corded power tools. 
       SUMMARY OF THE INVENTION 
       [0010]    There is disclosed herein an improved tool storage cabinet which avoids the disadvantages of prior devices while affording additional structural and operating advantages. 
         [0011]    A tool storage unit is disclosed comprising a cabinet structure having a plurality of surfaces defining a first interior space, a storage compartment defining a second interior space and configured to move between an open position extending from the first interior space and a closed position retracted within the first interior space, a stationary compartment sidewall fixed within the first interior space and adjacent the storage compartment such that access to the second interior space from the first interior space is prevented when the storage compartment is in the closed position, a plurality of power outlets positioned within the storage compartment such that each is accessible from the second interior space, and a locking feature for securing the storage compartment in the closed position. 
         [0012]    In a preferred embodiment, the storage drawer is a slidable drawer including a power cord coupled on one end to the plurality of power outlets and on another end to a power source, and a cable carrier for protecting the power cord within the cabinet as the storage compartment is moved between the open position and the closed position. 
         [0013]    It is an aspect of the invention to provide at least one support shelf configured to hold battery powered tools, batteries for such power tools, charging devices for the batteries of such power tools, or any combination of these components. 
         [0014]    In another embodiment, the present tool storage power drawer comprises wall panels, including a single sidewall panel affixed to each of a front, a rear and a bottom wall panel to thereby define an interior space. A plurality of power outlets positioned attached to at least one of the front, rear, bottom and sidewall panels are accessible from within the interior space, and a locking feature is used for securing the storage compartment in the closed position. 
         [0015]    It is another aspect of the present tool storage unit to provide a cabinet structure having a plurality of side surfaces and a top surface to define an interior space, a recessed area integral to the top surface, a cover hinged to the top surface and covering the recessed area, a power outlet positioned with the recessed area, and a plurality of tool storage compartments positioned within the interior space of the cabinet structure. Such embodiment may further comprise a power outlet positioned on the top surface of the cabinet structure outside of the recessed area. 
         [0016]    These and other aspects of the invention may be understood more readily from the following description and the appended drawings.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0030]    While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail a preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to embodiments illustrated. 
         [0031]    Referring to  FIGS. 1-12 , there is illustrated preferred embodiments of a tool storage cabinet or unit (e.g., a roll cab), generally designated by the numeral  10 , and its various components. The disclosed tool storage cabinet  10  includes a support frame  12  typically closed by wall sections  14  on three sides and a bottom wall  15 , leaving one side open for insertion of, for example, sliding drawers, and a top surface  16  which may be fixed or hinged for opening. The tool storage cabinet  10  may include a wheeled base attached at the bottom wall  15  for portability, as well as side and rear add-on components, all of which are well-known features of such tool storage cabinets. The tool storage cabinet  10  and its components, unless otherwise stated, are shown in  FIGS. 1-12  in a basic configuration so as to best illustrate the claimed features of this application. 
         [0032]    The claimed features of the present tool storage cabinet  10  include a power drawer  50  and a power surface  70  having a computer hatch  80 . The power drawer  50 , as will be discussed in greater detail below, is useful for charging cordless power tools during storage. The power surface  70  is similarly useful for charging batteries for cordless devices or for powering corded tools, as necessary. The integral computer hatch  80 , also provided with a power outlet, is capable of powering and storing computer and diagnostic equipment from the top surface  16 . 
         [0033]    Referring first to  FIGS. 1-9 , the power drawer  50  is preferably a sliding drawer which is capable of movement between an open and closed condition. The drawer  50  is shown to be open on one side—facing the interior to the storage unit—and at the top. This configuration allows convenient access to the drawer interior when in the open condition. The drawer is positioned upright to provide greater vertical storage space. However, a horizontal drawer (not shown) would be an acceptable alternative configuration. 
         [0034]    The existing walls of the drawer  50  are comprised of bottom wall  51 , front wall panel  52 , exterior sidewall panel  53 , and back wall panel  54 . The front wall panel  52  is designed with a drawer pull  57  and seals tight against the frame  12  of the storage unit  10  when the drawer  50  is closed. With the interior wall  18  of the storage unit  10  in place, access to the interior of the closed drawer  50  is restricted. The interior wall  18  also prevents other tools and debris from inadvertently entering the power drawer  50 , a result which may interfere with the equipment charging process. 
         [0035]    The bottom wall  51  is preferably spaced a distance from the bottom wall  15  of the storage unit  10  to thereby create a space, as illustrated in  FIG. 7 . Preferably, the back wall  54  of the power drawer  50  houses a four outlet power strip  58 . The cord  59  of the power strip  58  is capable of being housed within the space created below bottom wall  51 . A cable carrier  32  may be used to protect the integrity of the power strip power cord  59  as it is flexed repeatedly with the opening and closing of the power drawer  50 . The other end of the power cord  59  may be connected directly into a breaker box, for example, either on the unit  10  or by extending the cord  59  through the wall  14  of the unit  10  to a designated power source (not shown). 
         [0036]    Alternatively, the end of the power cord  59  may comprise a male plug for connecting to an external power source. Accordingly, an end of the cable carrier  32  would be preferably fixed at the wall  14  of the storage unit  10 . Additional cord  34  could extend from the back wall of the storage unit  10  to allow it to be plugged into a power source, such as a wall outlet (not shown) or generator (not shown). 
         [0037]    As noted, however, the power strip  58  may, of course, be secured to any of the power drawer  50  wall panels, including the bottom wall  51 , to provide electrical power within the drawer interior. Several such power strips may be used, if necessary. Further, while commercial power strips are suitable, the outlet configuration (e.g., 1×6 strip, 2×3 strip, etc.) as well as the number of outlets provided, may vary for different intended uses. The power strip  58  may be fixed within or integral to the drawer wall or movable from a fixed anchor point. Such alterations are well within the ability of those skilled in the relevant art. 
         [0038]    The exterior sidewall  53  is preferably provided with slots  36 , as shown in  FIG. 4 , to allow attachment of custom shelves  40 , shown for example in  FIGS. 6 ,  8  and  9 . The shelves  40  are preferably configured to support, for example, a battery charging unit  44  within the power drawer  50 . Openings may also be provided on some or all shelves  40  as a holster for cordless tools, as illustrated. A plurality of such specially configured shelves  40  may be attached within drawer  50 , if needed. The shelves  40  are preferably readily attachable and detachable to allow the power drawer  50  to be customized for the individual user. 
         [0039]    As mentioned above, the storage unit  10  preferably has an inner wall  18  which blocks access to the interior compartment of the power drawer  50  when the drawer is in a closed position. The remaining space of the storage unit  10  may be configured in any manner known and used by those skilled in the art. 
         [0040]    A lock  42  is preferably provided on the storage unit  10  such that the power drawer  50  may be locked in a closed position when desired. Alternatively, a lock (not shown) may be provided on the power drawer  50  itself to allow locking of the drawer  50  separate from the locking of the storage unit  10 . 
         [0041]    Referring now to  FIGS. 1-3  and  10 - 12 , two additional areas for placing power outlets can be readily understood. The top surface  16  of the storage unit  10  is a useful location for providing power. As with the power drawer  50  above, the power outlets may be configured as a strip or on a panel. While the referenced drawings illustrate the power strip  72  to be centered proximate a back edge of the top surface  16 , it may be desirable have the strip  72  further from the computer hatch  80 , for example. 
         [0042]    In a preferred embodiment, the top surface  16  provides a work surface and includes a protruding power strip  72 , having a plurality of power outlets  73 . The strip  72 , though extending from the top surface  16 , does not significantly impede the full use of the work surface. Alternatively, the outlet strip  72  may be recessed within the top surface  16  to minimize any possible interference potential. In either case, a cover (either integral or detachable—not shown) may be used for the entire strip  72  or on each of the individual outlets  73  to prevent damage to the outlets  73 —for example, from debris falling into the outlet openings—when the strip  16  is not in use. 
         [0043]    The workstation surface, as shown in  FIGS. 10-12 , has a raised perimeter  60  to prevent tools and parts from rolling off the storage unit  10 . The raised perimeter  60  provided may vary from a slight bump to a significant protrusion depending on the intended use. The raised perimeter  60  is preferably integral to the top surface  16 , but may be a detachable feature or a permanently affixed added feature. 
         [0044]    Referring to  FIGS. 10-12 , the top surface  16  of the unit  10  is also preferably equipped with a computer hatch  80 , including a recessed compartment  82  and a closable hinged protective cover  84 . The recessed compartment  82  is equipped with power via power strip  86  having a plurality of power outlets  87 . 
         [0045]    At least one integral power strip  86  is positioned in the recessed compartment  82 . With respect to the hatch  80 , the protective cover  84  includes a seal  85  at the perimeter to seal out dust and moisture when the cover  84  is closed ( FIG. 11 ). Hinged along a back edge, the hatch  80  includes air springs  88  to assist opening and retention of the cover  84 . 
         [0046]    The recessed compartment  82  should be deep enough to house, e.g., a notebook computer, MODIS, or other diagnostic equipment. It may be desirable to provide a textured or rubberized surface (not shown) within compartment  82  to provide some level of cushioning for equipment and to help minimize lateral movement and vibration. A latch  87  or similar mechanism to hold the protective cover  84  closed is preferably used on the hatch  80  for security purposes. For further security, the latch  87  may include a locking feature (not shown) requiring a key, combination, code, biometric print, card swipe or the like to unlock. 
         [0047]    While not shown in the appended drawings, it may be advantageous to provide a docking station within the recessed compartment  82 . The docking station might include direct connection to peripheral devices (e.g., printer, additional monitor(s), etc.). The docking station may also provide additional USB slots or other type of ports for add-on peripherals. 
         [0048]    Referring to  FIG. 12 , the back edge of the workstation surface is shown. A power cord receptacle  65  may be provided, from which point electricity is fed to the entire top surface  16  (i.e., to each power strip). Other attachment devices for adding, for example, lockers, shelving, or the like, may be included on the support frame  12  of storage unit  10 . 
         [0049]    A lock is preferably provided on the storage unit  10  such that compartments, possibly including the power surface  70 , may be covered and locked when desired. Alternatively, a lock (not shown) may be provided on each compartment drawer or cabinet to allow locking of the individual compartments separate from the storage unit  10 . 
         [0050]    Each of the power strips described herein may be comprised of 110 VAC and/or 12 VDC to accommodate most power tools and charging units. A 220 VAC power outlet may be supplied in special circumstances. 
         [0051]    The power strip, if 110 VAC, has a power cord (not shown) which extends from the power strip and can be plugged into, for example, a wall outlet or a gas generator. A cable carrier, as shown in  FIG. 7  for the power drawer  50 , may be used to protect the integrity of any power strip power cord where it may be flexed repeatedly. The cord which extends from the power strip  16  may exit the unit  10  at a back wall opening to allow it to be plugged into a power source, as previously mentioned, such as a wall outlet or gas generator. Obviously, with 12VDC power, the power source (a battery) can be retained within the storage unit  10  or positioned near the storage unit  10  for easy connection. 
         [0052]    The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of applicants&#39; contribution. The actual scope of the protection sought is intended to be defined in the following claims when viewed in their proper perspective based on the prior art.
