text: it will readily be appreciated by those skilled in the art that the present invention is not limited to the specific embodiments herein shown . thus , variations may be made within the scope and spirit of the accompanying claims without sacrificing the principal advantages of the invention . the present invention provides an adjustable inclined tool box that can both carry tools and simultaneously can be used as a support for an individual who is working in a supine position . the tool box can be adjusted to a ranging variety of heights so that it is inclined at a comfortable angle for the individual . in one exemplary embodiment , adjustable feet are located on the bottom surface of the tool box to adjust the tool box to a range of required heights . therefore , the tool box can be adjusted and positioned in the most ergonomic way for the user . in this embodiment , the present invention provides an inclined tool box that can be used as a support for a user lying in a supine position , comprising a base box , an inclined back rest with a lid , and at least one pair of adjustable feet . the tool box can carry tools , spare parts , and / or other objects for use in repair and maintenance projects . examples of objects found in the tool box include , but are not limited to , hammers , screwdrivers , tape measures , pliers , drills , saws , levels , utility knives , tape , flashlights , washers , nuts , bolts , screws , and nails . the tool box can be compartmentalized to hold similar objects in similar areas of the tool box . for a better understanding of the invention , reference will now be made to the drawings , and to the accompanying descriptive matter , in which there are described exemplary embodiments of the invention . referring to fig1 and 2 , the toolbox 1 of the invention has a base portion and a top surface . the base portion comprises a base box 2 having a bottom surface 8 , two side walls 9 , 10 and a back wall 11 , whereas , the top surface comprises a back rest 3 and a lid 4 . in one embodiment , the bottom surface 8 has a horizontally placed rectangular structure attached to the side walls 9 , 10 on both sides , to the back wall 11 at the back side and to the back rest 3 in the front side of the tool box . the back wall 11 has one top edge , one bottom edge and two side edges . the back wall may have a rectangular or square shape with a parallel top edge , a bottom edge and two side edges . the bottom edge of the back wall 11 is vertically attached to the bottom surface 8 of the base box 2 . both the side edges of back wall 11 are attached to the side walls 9 and 10 of the base box 2 . the top edge of the back wall 11 is attached with the back rest 3 . a lip or tab 12 is attached at the intersection 14 of the back wall 11 and the back rest 3 and extends beyond the back rest 3 . the lip 12 extending out from the high side of the back of the tool box is designed to fit over the edge of the lower part of a cabinet such as when the user opens the cabinet door and slides the tool box up against it . the lip 12 allows more comfort when lying on the tool box and inside of a cabinet , such as providing a smooth transition from the back rest 3 on to the cabinet space floor ( where typically the edge can be an irritant to the user when in a supine position ). the feet 7 ( see fig4 and 5 ), such as adjustable feet , can be adjusted such that the lip 12 just rests on the cabinet space floor . the lip 12 can have gentle radius where the lip meets the main body of the tool box and therefore , the person lying on his or her back inside the cabinet space no longer has the cabinet edge gouging into his or her back . in one embodiment , it is envisioned that the lip 12 can be pivotally hinged at the point of its attachment 14 to the main body of the tool box and can be folded in the upper or lower direction . this helps to keep the tool box in a vertically standing position when the tool box is rested on its broader back side . it is also envisioned in another embodiment that the lip 12 can be fixedly attached at the point of attachment 14 to the main body , such as through being molded as essentially an extension of back rest 3 . since the lip 12 does not bear any weight , a smoother surface from the tool box surface into the cabinet space floor surface can be created by a straight or hinged attachment of the lip 12 to the main body of the tool box . the side walls 9 and 10 are attached to the bottom surface 8 at the bottom edge , to the back wall 11 at the side edge , and to the back rest 3 at top edge . the side walls 9 and 10 have triangular structures inclined from the back to front direction of the tool box . therefore , base box 2 has the maximum height at the back side and minimum height at the front side . the triangular structure of the side walls 9 , 10 gives an inclined surface to the back rest 3 attached to the side walls 9 , 10 and back wall 11 . the top surface can have a hinged lid 4 attached to the back rest 3 for giving access to the inside chamber of the tool box 1 . the inside chamber of the tool box may have a plurality of compartments for storing and holding the tools of different shapes and sizes and ensuring a proper place in the tool box for a specific type of tool . the lid 4 can be shut when the tool box is used as a support ( as seen in fig1 ) or can be opened when a tool is needed from the tool box ( as seen in fig2 ). the lid 4 can be further comprised of a clasp 5 which along with its counterpart on the back rest 3 keeps the lid 4 firmly shut when required . the upper surface of the tool box comprising the back rest 3 and the lid 4 may be smooth or rough . in one embodiment of the invention , the lid 4 has non - slip rubber pads or tape 6 on it to help keep the user positioned on the surface of the tool box while lying in the supine position . the front side of the tool box can have a semi - circular or other shaped opening 13 to handle and carry the tool box . the tool box may be constructed of any typical material used to make tool boxes in general , such as wood , plastic , or metal . however , the tool box needs to be able to support the weight of a user lying against the tool box . the construction material of the tool box of the invention is not limited to only one material , but rather several different materials or a combination of different materials can be used for the purpose . for example , in one non - limiting embodiment , the base box 2 and the back rest 3 are made of a metal material , whereas the lid 4 and clasp 5 is constructed of plastic . fig3 illustrates the same embodiment of the tool box as shown in fig1 and 2 from a top view . the back rest 3 is illustrated along with the lid 4 . on the lid 4 is a clasp 5 for keeping the lid closed along with its counterpart on the back rest 3 . the optional non - slip rubber pads or tape 6 on the lid 4 are also shown in fig3 . fig4 shows a side view of one embodiment of the tool box . from this view , the feet 7 located on the bottom surface 8 of the tool box 1 can be seen . the feet 7 may be present at all four corners of the bottom wall , and there may be a combination of fixed feet ( such as , for example , non - slip rubber pads ), adjustable feet , or even no feet . for example , as shown in fig4 and 5 , one pair of fixed feet may be attached in the front side of the tool box and one pair of adjustable feet may be attached on back side of the tool box . the adjustable feet may be present at either of the sides also , depending upon the requirement of the user . the adjustable feet 7 are used to adjust the tool box to a range of heights in order to suit the user and position the tool box in the most ergonomic manner . these feet can be adjustable in a variety of manners . in one embodiment of the invention , the feet 7 can be adjusted through screw engagement with the bottom surface 8 of the tool box . in the embodiment shown in fig4 , the height of the top surface of the tool box and the relative inclination compared to the ground can be adjusted by adjusting the height of the adjustable feet 7 present toward the back portion of the tool box . the height of the back portion of the tool box and the angle of the back rest 3 relative to the ground will vary depending on the relative heights of each pair of adjustable feet present on the front and back portion of the tool box ( or , alternatively , if adjustable feet are only located on the back portion of the tool box ). the higher the feet are adjusted at the back portion of the tool box , the higher the height of the back portion of the tool box and the larger the angle will be between the back rest and the ground . this allows the user to change the incline of the back rest according to the working space available and the comfort of the user . the adjustment can also be made so that the lip 12 gently rests on the cabinet space floor when the tool box is pushed up against the cabinet , thereby providing a smooth transition from the back rest 3 of the tool box to the cabinet space floor . fig5 illustrates a bottom view of one embodiment of the tool box . the bottom surface 8 is shown comprising a pair of fixed feet 7 ( such as , for example , non - slip rubber pads ) towards the front portion of the tool box and a pair of adjustable feet 7 towards the back portion of the tool box and which allow the incline of the tool box ( and back rest 3 ) to change . the lip 12 extending beyond the back rest 3 from the high side of the back of the tool box and the semi - circular opening 13 to handle and carry the tool box are also illustrated . in one example , the tool box 1 has a length of approximately 59 cm ( 23 . 2 inches ) and a width of approximately 28 cm ( 11 inches ). the lid 4 has a length of approximately 40 cm ( 15 . 8 inches ) and a width of approximately 20 cm ( 7 . 9 inches ). further , the clasp has a width of about 13 cm ( 5 . 1 inches ). these dimensions of the tool box are only one example and are given for better understanding of the invention . there are many other examples that fit the present invention depending on the need of the user . the tool box of the present invention may be constructed with different dimensions as per user requirements . a tool box may need to be smaller due to the constraints of the space in which it will be used . the tool box may be bigger if bigger tools are required and the working space allows for a bigger tool box . in general , the dimensions of the tool box can vary from about 13 cm to about 100 cm in width and from about 30 cm to about 150 cm in length . the ratio of the dimensions can also vary and are not limited to the ratio shown in this example . the foregoing detailed description of embodiments refers to the accompanying drawings , which illustrate specific embodiments of the invention . other embodiments having different
