Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to the field of wheel rims for pneumatic tires of a vehicle. More particularly, the present invention relates to the field of wheel well obstructor bands for wheel rims of a vehicle. 
     2. Description of the Prior Art 
     Specifically, pneumatic tires are commonly mounted on a wheel rim. The wheel rim has an annular narrow wheel well which effectively reduces the diameter of the wheel well all around its circumference. Such a wheel well, sometimes called a drop-center type wheel rim, facilitates the mounting of a pneumatic tire on the wheel rim. When it is desired to install the tire onto the wheel rim, one side of the bead can be placed around the bead retaining flange and into the wheel well, thus enabling the diametrically opposing side of the bead to be placed over the bead retaining flange on the other side of the wheel rim. Removal of the tire is accomplished in the reverse manner. 
     After the tire is installed and the tire inflated with its bead seated against the flanges, the wheel well serves no purpose. The presence of the wheel well, however, has been found to pose safety problems. When pressure is unintentionally lost from the tire due to a blow out or puncture during operation, the wheel well becomes available to the bead of the tire. If the bead of the tire falls into the wheel well, it is possible for the diametrically opposite sides of the bead to unintentionally fall off the bead retaining flange, and thereby the entire bead can fall off the flange. When the bead of the tire is lost from the bead retaining flange, serious loss of control of a vehicle upon which the tire is mounted can result. 
     Prior art band-type well obstructors have been proposed for obstructing this wheel well so that, in the event of deflation of the tire during operation, the interior of the wheel well will not be available to the bead of the tire, thereby insuring that the tire will remain on the wheel rim. However, wheel well-fillers of current designs have to be made individually for different types of wheels of different diameter and especially for wheel wells of different effective depths. None of the known prior art wheel well obstructors is adjustable in depth. 
     The following two (2) prior art patents are found to be pertinent to the field of the present invention: 
     1. U.S. Pat. No. 4,694,874 issued to White on Sep. 22, 1987 for “Wheel Well Obstructor For A Wheel Rim” (hereafter the “White Patent”); and 
     2. U. S. Pat. No. 5,435,368 issued to Lüst on Jul. 25, 1995 for “Tire-Retention Device And Wheel Rim” ((hereafter the “Lüst Patent”). 
     The White Patent discloses a wheel well obstructor for a wheel rim for obstructing the well of the hub of a wheel rim. The wheel obstructor has an inextensible band with integral circular protrusions mechanically extruded onto the band. The circular protrusions extend radially inwardly to abut against the base of the wheel well to retain the band in position surrounding the wheel well, and to resist crushing under the weight of the vehicle in the event of deflation of the tire. 
     The Lüst Patent discloses a well-filler of variable width for a drop-center wheel. The well filler has a band for circumposing the wheel rim in the well in engagement with a plurality of segments and mutually engageable connectors at first and second ends of the band. The connector means is adjustable for tightening of the band in the well around the rim. Engagement of the band with the segments is such that when the band is tightened in the well of a wheel rim, the segments are urged in directions transverse to the band so that the width of the well-filler matches that of the well. 
     It is desirable to provide an improved wheel well obstructor band with the capability of rapidly adapting to a plurality of different types of wheels of different diameter and especially for wheel wells of different effective depths. It is also desirable to provide a unique tightening hand tool for installing the improved wheel well obstructor band to a plurality of different types of wheels in a much more efficient way than prior art hand tools. 
     SUMMARY OF THE INVENTION 
     The present invention is an improved removable wheel well obstructor band which serves as a stable platform for supporting the beads of a flat tire, thereby resulting in a controlled run-flat tire capability. 
     The removable band-type wheel well obstructor is used for obstructing the interior of an annular wheel well of a wheel rim, wherein the wheel well has a predetermined radial depth. The obstructor includes a two-piece annular band of inextensible material of a predetermined axial width, a thickness which is substantially less than the depth of the wheel well and is adapted to circumferentially surround the wheel well, and is provided with an opening through its circumference. A plurality of radially and inwardly projecting adjustable snap-on frusto-cone shaped shims of a predetermined height are attached to and spaced around the circumference of the band and are adapted to be received into the wheel well. A plurality of height adjusters are respectively attachable to the plurality of snap-on shims for accommodating a plurality of different depths of wheel well. Means are also provided for tensionably retaining the wheel well obstructor band on the wheel rim. 
     It is an object of the present invention to provide an improved removable wheel well obstructor which includes a plurality of removable and attachable shims for adapting to the depth of a wheel well. 
     It is also an object of the present invention to provide an improved removable wheel well obstructor which includes a plurality of different thicknesses of a height adjuster that are attachable to the shims so that the plurality of shims can be adapted to a plurality of different depths of a wheel well. 
     It is an additional object of the present invention to provide an improved removable wheel well obstructor which includes a fastener assembly for drawing together spaced apart adjacent ends of the band portions. 
     It is a further object of the present invention to provide an improved removable wheel well obstructor wherein the plurality of shims provide positive resistance to movement of the wheel well obstructor into the wheel well of the wheel rim under the weight of the vehicle, and they also reduce the incidence of slippage or rotational movement of the obstructor with respect thereto. 
     It is still a further object of the present invention to provide a tightening hand tool to be used with the improved removable wheel well obstructor to draw the two ends of the band of the wheel well obstructor together so that tension is released, thereby allowing the installer to tighten the fastener to secure the wheel well obstructor to the wheel rim. 
     In the preferred embodiment of the present invention, the improved removable wheel well obstructor is a two-piece type band. 
     In an alternative embodiment of the present invention, the improved removable wheel well obstructor is a unitary type band.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims. 
     Described briefly, the present invention is a removable annular wheel well obstructor for obstructing a plurality of different inwardly disposed annular wheel wells of a plurality of wheel rims, wherein each wheel well of each wheel rim has a predetermined radial depth. 
     Referring to FIG. 1, there is shown at  10  a preferred embodiment of the present invention removable wheel well obstructor installed on a wheel well  2  of a wheel rim  4 . This wheel well obstructor  10  has at least two semicircular annular band portions  12  and  14  that are fabricated of a sturdy and relatively inextensible material, such as steel or other suitable material and coated with zinc plate. 
     Referring to FIGS. 1,  2 ,  3 ,  4  and  5 , the band portions  12  and  14  are interconnected at its adjacent ends  24  to form an annular band member  30  of inextensible material of a predetermined axial width “W” and having an opening  50  through its circumference. The annular band member  30  has a thickness “T” that is substantially less than the predetermined radial depth “RD” of the wheel well  2  and being adapted to circumferentially surround the wheel well  2  of the wheel rim  4  and linear with the bottom surface  5  of the wheel rim  4  (see FIG.  4 ). 
     Referring to FIGS. 1,  2  and  3 , each of the band portions  12  and  14  are substantially identical, and to the extent they are, only one will be described in detail. The band portion  12  includes a plurality of radial apertures  28  that extend therethrough and are equally spaced apart circumferentially around the band portion, and a pair of a plurality of slotted apertures  32  which are equally spaced apart around the circumference of the band portion and parallel to each other and the plurality of radial apertures  28 . The band portion  12  includes flanges  26  at opposite ends  24  which are bent inwardly, and preferably are bent partially around in the form of a semi-circular loop. Each flange  26  is adapted to receive and hold one end of a typical fastener  34 . These typical fasteners  34  are used with the present invention removable wheel well obstructor  10  for securing the adjacent ends  24  of the band portions  12  and  14  together as shown and since the parts of the fastener  34  are well known in the art, the description thereof will only be described in general terms. Because of these fasteners  34 , assembly and disassembly of the annular band member  30  is thereby simplified. When tightened, the ends of the fastener  34  will bear snugly against the flanges  26  to tensionably draw together the adjacent ends  24  of the band portions  12  and  14  to hold the well the band member  30  in tension surrounding the wheel well  2  of the wheel rim  4 . 
     Referring to FIGS. 2 and 3, the band portions  12  and  14  have holes  38  which are used so that the fastener  34  can be conveniently installed onto the flanges  26  from the outside circumference of the band member  30  after loosening the fastener. When the band portions  12  and  14  are urged apart by imparting tension to the band member  30 , the ends of the fastener  34  will be securely held in position by the flanges  26  as long as this tension exists. 
     Referring to FIGS. 4,  5 ,  6 ,  8  and  9 , there is shown at  40  one of the plurality of attachable and detachable shims or means used with the present invention removable wheel well obstructor  10 . Each of the plurality of shims  40  is substantially identical, and to the extent they are, only one will be described in detail. The shim  40  has a predetermined height “H” and is rigid and lightweight and easy to form, thereby making the removable wheel well obstructor  10  less prone to being crushed under the weight of the vehicle tending to press the bead of the tire against the band member  30 . The shim  40  has a generally receivable distal frusto-cone shaped body  42  and an attachable proximal stem  44  which is integrally formed at the bottom of the body  42 . The frusto-cone shaped body  42  has a round shaped distal end surface  52  with a bore  54  for respectively receiving a plurality of height adjusters or means  16  as shown in FIGS. 8 and 9. The round shaped surface distal end  48  of the shim  40  significantly increases the coefficient of friction between the shims  40  and the base  3  of the wheel well  2  of the wheel rim  4  when the wheel well obstructor  10  is installed. This helps to prevent undesirable rotation of the wheel well obstructor  10  with respect to the wheel well  2  of the wheel rim  4 . The shims  40  are attachable to the band portions  12  and  14 , wherein the proximal stem  44  of each shim is respectively snapped onto the plurality of radial apertures of the band portions  12  and  14  of the annular band member  30 . The proximal stem  44  of each shim  40  may have an annular groove  46  for securing it to the band portions  12  and  14  (see FIGS.  4  and  5 ). The frusto-cone shaped body  42  of the shim  40  may have an annular groove  48  located at the bottom for reducing material used and cost of the shims  40 . 
     Referring to FIGS. 5,  7 ,  8  and  9 , there is shown at  16  one of the plurality of attachable and detachable height adjusters or members used with the present invention removable wheel well obstructor  10 . Each of the plurality of height adjusters  16  are substantially identical, and to the extent they are, only one will be described in detail. The height adjuster  16  has a generally round distal end  18  and an attachable proximal stem  20  which is integrally formed at the bottom of the distal end  18 . The proximal stem  20  is press-fitted to the bore  54  of the shim  40  for further increasing the height “H” of the shim  40  so that the shim  40  can match the radial depth of a plurality of different radial heights “RD” of wheel well. The thickness T 1  or height of the distal end  18  of the height adjuster  16  can vary depending on the radial height of the wheel well  2  (see FIG.  9 ). 
     Referring now to FIG. 10, a portion of the wheel well obstructor  10  of the present invention is illustrated in cross-section installed surrounding the wheel well  2  of the wheel rim  4 . The round shaped distal end surface  52  of the shim  40  abuts against the wheel base  3  of the wheel well  2 . A pneumatic tire  6  is installed with its bead  7  seated against the bead retaining flanges  8  of the wheel rim  4  in the normal position. 
     In FIGS. 4 and 10, the shims  40  are approximately equal in height to the radial depth “RD” of the wheel well  2 . It is not necessary, however, that the height “H” of the frusto-cone shaped body  42  of the shim  40  be equal to the radial depth “RD” of the wheel well  2 . Due to the height adjusters  16 , a plurality of different radial depths of wheel well  2  can be accommodated as shown in FIG.  11 . The present invention can be installed in a deeper wheel well, as shown in FIG. 11, with the aid of the height adjusters  16 , where the distal end  18  of the height adjuster  16  abuts against the wheel base  3  of the wheel well  2 . A pneumatic tire  6  is installed with its bead  7  seated against the bead retaining flanges  8  of the wheel rim  4  in the normal position. Therefore, it can be seen that the present invention provides a band-type well obstructor which is sturdy, easy to form and to install, and which is adaptable to a wide variety of well depths. 
     Referring to FIG. 12, there is shown at  100  an alternative embodiment of the present invention removable wheel well obstructor  100 . In this embodiment, the at least two semicircular annular band portions  12  and  14  shown in FIGS. 2 and 3 are substituted with a single band member  130  with its ends interconnected together by a fastener. Since it assembles and functions the same as previously described above, the description thereof will not be repeated. Height adjusters  16  are not shown attached to the shims  40  in this figure, but can be used in this alternative embodiment of the present invention removable wheel well obstructor  100 . 
     The present invention conforms to conventional forms of manufacture or any other conventional way known to one skilled in the art, and is of simple construction and is easy to use. The shims  40  and height adjusters  16  can be made from several materials. The manufacturing process which could accommodate the construction of the shims and height adjusters may be injection, therefrom, etc. or other molding process. By way of example, the shims and height adjusters can be made of polyurethane material, nylon material, plastic material or any other suitable material. 
     FIG. 13 shows a tightening hand tool  60 . FIG. 14 shows the tightening hand tool  60  in a released or relaxed condition. FIG. 15 shows the tightening hand tool  60  in a compressed or torqued condition. Referring to FIGS. 13,  14  and  15 , there is shown at  60  a tightening hand tool to be used in conjunction with the present invention removable wheel well obstructor  10 . The tightening hand tool  60  allows a user to draw the adjacent ends  24  of the pair of band portions  12  and  14  closer together to impart tension to the annular band member  30 , thereby allowing the user to tighten the fasteners  34  to secure the wheel well obstructor to the wheel well of the wheel rim. 
     The hand tool  60  comprises a lever member  61  and a pair of movable linkage arms  66  and  68 . The lever member  61  has a hand portion  62  and an attachment portion  64 . The first linkage arm  66  has a hook end  70  or connecting end and an attachment end  72  which is pivotably connected to the attachment portion  64 . The second linkage arm  68  also has a hook end  74  or connecting end and an attachment end  76  which is pivotable connected to the attachment portion  64  and located above the attachment end  72  of the first linkage arm  66 . 
     In operation, the hook end  70  of the first linkage arm  66  is inserted into one of the plurality of slotted apertures  32  on the band portion  14  while the hook end of the second linkage arm  68  is inserted into one of the plurality of slotted apertures  32  of the band portion  12  (see FIG.  14 ). The hand portion  62  is pulled or pushed forward as indicated with arrow  80  shown in FIG. 14, thereby allowing the adjacent ends  24  of the band portions  12  and  14  to draw closer together as indicated with arrows  82  and  84  in FIG. 15, so that tension is released, where the installer or user can tighten the fastener  34 . 
     The tightening hand tool  60  conforms to conventional forms of manufacture or any other conventional way known to one skilled in the art, and is of simple construction and is easy to use. By way of example, the hand tool is made of steel or any other rigid material.
