     DETAILED DESCRIPTION 
       [0012]    The preferred embodiment and other embodiments, which can be used in industry and include the best mode now known of carrying out the invention, are hereby described in detail with reference to the drawings. Further embodiments, features and advantages will become apparent from the ensuing description, or may be learned without undue experimentation. The figures are not necessarily drawn to scale, except where otherwise indicated. The following description of embodiments, even if phrased in terms of “the invention” or what the embodiment “is,” is not to be taken in a limiting sense, but describes the manner and process of making and using the invention. The coverage of this patent will be described in the claims. The order in which steps are listed in the claims does not necessarily indicate that the steps must be performed in that order. 
         [0013]    Broadly, an embodiment of the present invention generally provides a toolbox or safe that can fit inside the wheel of a spare tire and serves the purpose of holding the spare tire to the vehicle. 
         [0014]    Embodiments of a spare tire may be attached to the exterior of the rear end or side of a vehicle. The vehicle may be an SUV, trailer, a recreational vehicle or a semi-truck. Embodiments may provide a virtual automotive backpack or spare tire carrier that is also a steel, lockable tool box, inconspicuously hidden behind the spare tire. Users may use embodiments to keep emergency tools at the ready or lock up your valuables when the user leaves the vehicle. Embodiments may provide storage for gloves, jumper cables, tow straps, plug kit, tire gauge, multi tools, flashlight, first aid kits, or other items to be stored. 
         [0015]    Embodiments of a tool safe may replace the exterior vertically mounted spare tire carrier of original equipment. Embodiments may be mounted to the vehicle using a specially manufactured backing plate, which may be first fitted to the vehicle, and then to the tool safe using approximately five mounting holes or apertures in the bottom section of the front panel. Alternatively, the tool safe may be welded or fastened in another manner to a steel after-market spare tire carrier. 
         [0016]    In an exemplary embodiment, a tool safe may have specific measurements for a specific wheel, which would vary depending on wheel size. For example, an embodiment of a tool safe that measured substantially 14¾ inches in outer diameter and 8½ inches deep would fit into a 17 by 8½ inch aluminum wheel of an original equipment manufacturer (OEM) Jeep™ vehicle. Embodiments may, for example, fit and work with up to 20″ wheels with a depth of 8″ standard width, with optional depths of 10″ and 12″. 
         [0017]    The body of an embodiment of a tool safe may be a cylinder having a diameter and circumference determined by the inside dimensions of the wheel into which the embodiment will be fitted. The dimensions may be determined by measuring the length of the innermost section of the inside of the wheel and extending to the mounting pad or axle hub mounting surface. For example, if the inside diameter of the wheel is 14¾ inches, that number is multiplied by 3.14 to a length of 46.32 inches of material which is then rolled into the cylinder which makes the body  18 . The body may also be made from pipe having an acceptable diameter and thickness. 
         [0018]    As depicted in  FIG. 1 , a spare wheel  10  and tire  12  for a vehicle  16  may include, as original equipment, an exterior spare tire carrier  14 , which may be replaced by an embodiment of a tool safe. The tire carrier  14  may be vertically mounted on a mounting plate  32 , and embodiments of the present invention may replace the tire carrier  14  to provide a lockable tool box. Embodiments may support other orientations and configurations, such as horizontally mounted underneath the vehicle  16 , in a trunk of the vehicle  16 , or mounted directly to the vehicle  16  itself. 
         [0019]    As depicted in  FIG. 2 , embodiments of a lockable tool safe  40  may include a cylindrical body  18 , a back plate  20 , and a front plate  22  with a lower section and an access panel  24  in an upper section. The access panel  24  may form the top front of the front plate  22 , and may be joined to the bottom section of the front plate  22  by a hinge  28 . The access panel  24  may also have a lock  30  to keep the access panel  24  locked shut against a metal lip  26  at the top of the body  18 . The back plate  20  may have protruding wheel lug studs  36  to hold the spare wheel  10  and tire  12 . In an embodiment, the bottom section of the front plate  22  may have holes and bolts  38  to use in attaching the tool safe  40  to a mounting plate  32  or other mounting bracket. 
         [0020]    In an embodiment, the back plate  20  of a tool safe  40  may be substantially a solid circle having the same diameter as the inside of the body  18 . The access panel  24  may enclose 50% or less of the front plate  22 , and the bottom section of the front plate  22  may enclose 50% or more of the front plate  22  of the tool safe  40 . Other embodiment may have a differently-sized access panel  24 . Embodiments of a body  18  may be made of 1/16″ thick material depending on the material and the back plate  20  and upper and lower sections of the back plate  20  may be made of ⅛-inch thick material, depending on the material. One could use thicker or thinner material and/or steel/aluminum/hard formed plastic or other material of satisfactory strength. The body  18  may be enclosed by the back plate  20  and front plate  22 , arranged so as to fit inside the edge of the cylindrical body  18  to be attached. Embodiments may include a wheel attachment mechanism with wheel lug studs to hold the back plate to the wheel, and a vehicle attachment mechanism with bolts to hold the front plate to the vehicle. 
         [0021]    To make an embodiment, a back plate  20  of a tool safe  40  may be welded solidly around one end of the cylindrical body  18  to enclose the entire back side of the cylinder. The bottom section of the front plate  22  may be welded onto the other end of the body  18  of the tool safe  40 . A hinge  28  may be welded between the bottom section of the front plate  22  and the top section access panel  24 . Wheel lug studs  36  may be installed in the back plate  20  to hold the spare wheel  10  and tire  12 . The stud heads may be located on the inside and then welded with their threaded ends protruding outside to mount and fasten the wheel  10  to the vehicle. 
         [0022]    As depicted in  FIG. 3 , the bottom section of the front plate  22  may be attached to a mounting plate  32 , which may have mounting bolts  34 . The access panel  24  on the front plate  22  may have a hole drilled in the horizontal center about 1 inch from a top edge for the installation of a lock  30  which can be a thumbscrew or combination lock. A ½″ wide metal lip  26  may be welded inside the top section of the cylindrical body  18 , encircling the inner top half or other portion of the cylinder where the access panel  24  closes, and may be placed ¼″ from the outer edge of the cylinder for the purpose of providing an access panel seat and a cam lock anchor for keeping the top section access panel  24  closed and locked. 
         [0023]    As depicted in  FIG. 4 , an embodiment of a back plate  20  may have a number of holes for bolts or protruding wheel lug studs  36 , such as three studs positioned at a 2.5″ radius,  5 ″ diameter on center, with two grouped at the top or bottom and one centered on the opposite side of center. Wheel manufacturers may reference this as a “5 on 5” lug pattern, specifically meaning 5 lug holes on a centered 5 inch diameter pattern. However, for the purpose of holding a spare tire  12  and wheel  10 , only three lug studs  36  may be appropriate. 
         [0024]    When installed, the tool safe may provide not only a place to safely mount and store a spare wheel and tire, but also enclose secure storage space inside the spare tire wheel. It may have an opening on its front, the vehicle facing side, in which tools, gear or valuables may be stored and it can be locked securely. 
         [0025]    An embodiment of a vehicle wheel mounted tool safe may comprise: a cylindrical body having two ends; a back plate attached to one end of the cylindrical body, the back plate adapted to be attached to a tire wheel; a front plate comprising a bottom section  5  attached to the other end of the cylindrical body, the front plate adapted to be attached to a mounting bracket on a vehicle, the front plate having a top section hingeably attached to the bottom section; and a locking mechanism in the top section of the front plate. When the back plate is attached to the wheel of a spare tire and the bottom section of the front plate is attached to the mounting bracket, the cylindrical body, together with the back plate and front plates, provide a vehicle storage safe that is accessed through the top section of the front plate and secured by the locking mechanism in the top section.
