RELATED PATENT APPLICATION 
     This application is a continuation-in-part of U.S. Patent Application Ser. No. 329,442 filed on Feb. 5, 1973 by the same inventor issued on Jan. 14, 1975 as U.S. Pat. No. 3,860,297. 
    
    
     BACKGROUND OF THE INVENTION 
     Heretofore various attempts have been made to provide for mounting wheel accessories on vehicle wheels. These attempts, for the most part, have necessitated the provision of mounting fixtures which must either be attached to the wheel each time a wheel accessory is to be used or, if permanently mounted, require the use of tools and special fasteners in order to secure the wheel accessory thereto. 
     This invention provides a vehicle wheel mounting fixture of the type which may be readily mounted upon an existing wheel through the utilization of the lugs conventionally used to secure the associated wheel to its hub, the fixture being so constructed as to enable its permanent retention beneath a conventional hubcap. 
     It is contemplated that the mounting fixture be mountable on the associated vehicle wheel without requiring the removal of all of the associated nuts, thereby maintaining the wheel secure as the accessory is being mounted. 
     It is a further feature of this invention that the wheel accessories to be mounted from the fixture may be readily engaged with and disengaged from the mounting fixture without the use of tools and by a person possessing only minimal mechanical ability. 
     A full understanding of the construction of this invention, together with further novel features and advantages, will be had from the following detailed description of preferred embodiments thereof, taken in conjunction with the attached drawings.

     DETAILED DESCRIPTION 
     Referring now more specifically to the drawings the numeral 10 generally designates a conventional vehicle wheel having a pneumatic tire casing 11 mounted thereon. The wheel 10 includes a central portion 12 provided with circumferentially spaced bores 14 through which hub mounted thread studs 16 extend. A plurality of threaded nuts 18 are threadedly engaged on the outer ends of the studs 16 for securing the wheel 10 to the hub. 
     A vehicle wheel accessory mounting structure or fixture generally referred to by the reference numeral 20 is provided and includes a centrally apertured mounted plate 22 having a cylindrical hub portion 24 projecting outwardly from one side thereof. A plurality of circumferentially spaced bores 26 are formed through the plate 22 about the exterior of the hub portion 24. The bores 26 are of a size to snugly receive the studs 16 therethrough with a single bore 28 being enlarged and of a size to receive one of the nuts 18 therethrough. Accordingly, from FIG. 1 of the drawings it may be appreciated that in order to secure the vehicle wheel accessory mounting fixture 20 to the wheel 10 it is only necessary to remove four of the nuts 18 and to thereafter place the plate 22 over the outer surface of the central portion 12 of the wheel 10 with the remaining wheel retaining nut 18 received through the bore 28 and the other studs 16 received through the bores 26. Thereafter, the removed nuts 18 may be again threaded on the studs 16 to secure the fixture 20 to the wheel 10. This manner of mounting the fixture 20 on the wheel 10 is significant as it provides for a positive retention of the wheel 10 at all times which in turn eliminates the necessity of jacking the wheel 10 up from the ground when mounting the accessory. 
     As may best be seen from FIG. 1 of the drawings the hub portion 24 of the fixture 20 includes diametrically opposite longitudinally extending radial slots 30 and diametrically opposite bayonet slots 32 including slightly reentrant inner end portions 34. The purpose of the slots 30 and 32 is to secure an accessory mounted adapter 40 as will be hereinafter more fully set forth. 
     The specific structure of the accessory adapter 40, which can accommodate a variety of accessories, may be seen to best advantage in FIGS. 3, 4 and 9 of the drawings wherein it will be noted that the adapter 40 includes a cylindrical body 42 having an end wall 44 closing its outer end. The cylindrical body 42 mounts longitudinally extending generally T-shaped torque accommodating internal ribs 46 disposed diametrically opposite each other. The end wall 44 is centrally apertured as at 48 and has an elongated axially extending shank member 50 and slidably received therethrough. The inner end of the shank member 50 adjacent the open end of the cylindrical body 42 is provided with a crosshead 52 extending generally along a diameter of the cylindrical body 42. The free end portions of the crosshead 52 are slightly rearwardly offset as at 54 toward the closed end of the cylindrical body 42. It will further be noted that the free ends of the crosshead 52 terminate but a slight distance inwardly of the inner surface of the cylindrical body 42. 
     The end portion of the shank member 50 remote from the crosshead 52 and outward of end wall 44 is provided with a circumferentially extending radially outwardly projecting abutment flange 56 and a contoured handle portion 58 on the terminal end thereof. A compression spring 60 is disposed about the shank member 50 between the abutment flange and the outer surface of the end wall 4 and thereby serves to yieldingly bias the shank member 50 toward an outwardly displaced position. 
     When applying the adapter 40 and associated wheel accessory to the mounting fixture 20 after the latter has been secured to the wheel 10, the cylindrical body 42 of the hub 40 has its open end telescoped over the outer free end of the hub portion 24. The handle 58 is turned to register the free ends of the crosshead 52 with the open ends of the slots 32 for movement thereinto with the T-shaped ribs 46 being slidingly received in the slots 30 and overlying the inner surfaces of the hub portion 24 on inner sides of slots 30. After the ribs 46 have been seated in the inner ends of the slots 30, the handle 58 is pushed inwardly and rotated to seat the opposite ends of the crosshead 52 in the inner ends 34 of the slots 32. The handle 58 is then released with spring 60 slightly retracting the opposite ends of the crosshead 52 into the inner end portions 34 of the slots 32. As will be appreciated, the adapter 40, and hence the accessory, is thus fixedly mounted in a manner which would require manual manipulation of the adapter 40 to affect its removal. Further, while the spring loaded crosshead 52 mounts the adapter 40, the opposed ribs 46 constitute the load accommodating means or torque transferring members. 
     With attention now invited to FIG. 5 of the drawings, there may be seen a form of wheel accessory referred to by reference numeral 51. The wheel accessory 51 comprises a rigid wheel 53 having the central hub portion or mounting adapter 40 and an outer periphery mounting a pneumatic tire 55 inflatable through a valve 57. The wheel accessory 51 comprises a spare wheel which may be secured, through the adapter, over the outside of the wheel 10 in the event the pneumatic tire 12 loses its air. It is of course to be understood that the tire 55 is deflated prior to installation and inflated once it is installed. This will enable the disabled vehicle to be moved to a service area without the need for changing the defective tire. 
     A further form of wheel accessory is illustrated in FIG. 6 and is referred to by reference numeral 62. The accessory 62 includes the hub 40 and may therefore be readily removably engaged with the fixture 20. The wheel accessory 62 includes an outer circumferential band 66 provided with radially outwardly projecting lugs 68 for added ground traction in snow, ice, mud, etc. The band 66 may be either of the inflatable type or non-inflatable type as desired. Furthermore, it may be desirable to elongate the adapter 40 to permit the accessory 62 to be mounted outside the vehicle fender. 
     In FIG. 7 of the drawings there is illustrated a modified form of mounting arrangement including a fixture referred to in general by the reference numeral 110. The fixture 110 is similar to the fixture 20 in that it includes a base plate 112 having a plurality of small stud receiving bores 114 formed therethrough as well as a larger nut receiving bore 116. In addition, the fixture 110 includes a hub portion 118 having diametrically opposite longitudinal slots 120 formed therein corresponding to the slots 30. However, in lieu of the bayonet slots 32 provided in the hub portion 24, the hub portion 118 includes diametrically opposite spring clips 122. These clips 122 each project through the hub wall and include an outer leg 123 fixed to the outer surface of the hub and a free inner leg 125 terminating in a looped end 127. An outwardly projecting shoulder 129 is formed between legs 123 and 125. 
     A wheel accessory adapter 124, also illustrated in FIG. 12, includes a hub portion 126 corresponding to the hub portion 40 and provided with internal T-shaped ribs 128 similar to the ribs 46 for reception within slots 120. However, in lieu of the shank member 50 and crosshead 52 of the hub portion 40, the hub portion 126 includes diametrically opposite axially extending closed ended slots 132 into which the spring clip shoulders 129 are radially projectible as the hub portion 126 telescopes over the hub portion 118. Accordingly, it may be seen that the wheel accessory 124, while capable of being positively locked to the fixture, may be readily removed therefrom, the release of the hub portion requiring an outward pulling on the looped ends 127. Incidently, it will be noted that the spring clips 122 and related slots 132 can be longitudinally offset to require a specific alignment of the accessory. This modified form of mounting arrangement may be desireable for use on wheels with a projecting wheel hub such as the front wheels of automotive vehicles. 
     It is to be understood that the mounting fixture illustrated in FIG. 7 may be used in lieu of the mounting fixture illustrated in FIGS. 1 - 4 with any of the accessories described herein. 
     As previously indicated, the T-shaped ribs of the various adapter hubs of the wheel accessories key into the corresponding slots of the fixture in order to lock the hubs to the fixture for the transfer of torque from the fixture to the hubs. In addition, the spring urged locking members of the various wheel accessory hubs serve to maintain the wheel accessories of the associated fixtures 20 against outward axial shifting relative thereto. 
     Having described the invention, it will be appreciated that some modifications may be made to the precise configuration, without departing from the scope or spirit of the invention as defined by the following claims. 
     Referring now to FIGS. 8 and 9 of the drawings there is shown a wheel accessory represented generally by the reference numeral 200. The wheel accessory 200 has two basic parts, with the first part 202 being adapted for permanent or semi-permanent mounting on a conventional vehicle wheel. The first part has flange 204 with holes 206 for receiving studs 208 of the conventional vehicle wheel shown in phantom lines. Attached to the studs 208 are the conventional bolts to 10 for mounting an automobile wheel. Formed integral with flange 204 is cylinder 212. The cylinder 212 has opposing slots 214 formed in the outer portion thereof as shown in FIGS. 8 and 9. Also cylinder 212 has a solid center 216 with a threaded connection 218 formed therein. 
     The second half 220 of the wheel accessory 200 is mounted to an accessory wheel shown in phantom lines which could be attached to the conventional automobile tire when desired. The second half 220 has a flange 222 with conventional stud bolts 224 permanently contained therein by any conventional means such as welding. The accessory wheel then may be connected to the second half 220 by nuts 226. Formed integral with flange 222 is a cylindrical portion 228 that is slightly larger than cylinder 212 of the first half 202. However, cylindrical portion 228 has two inward extensions 230 designed to mate slot 214 of the half 202 in a spline type of connection. A center body 232 has a T-bolt extending therethrough that is retained into position by nuts 236 on each side of the center body 232. 
     If the first half 202 is mounted to the conventional automobile wheel by disconnecting nuts 210 and inserting studs 208 through holes 206 of flange 204 and again tightening the nuts 210 into position; thereafter, the accessory wheel, to which is mounted the second half 220, may be connected to the conventional automobile tire by sliding inward extension 230 into slots 214 and tightening T-bolt 234 to the threaded connection 218 of the first half 202. This provides a very easy and economical means for connecting a dual wheel to the conventional automobile tire. This is especially useful for snow, ice or mud where extra traction is needed. 
     Referring now to FIG. 10 there is shown another modification with a wheel accessory 238 being one solid integral body. The wheel accessory 238 is connected as previously described for the wheel accessory shown in FIG. 1 by having holes 240 in flange 242 for receiving studs 244 of the conventional automobile wheel. An enlarged hole 246 receives not only stud 244 but also nut 247 so that the conventional automobile wheel may be retained into position while attaching the wheel accessory 238. 
     The flange 242 is formed integral with cylinder 250 which has another flange 252 contained on the opposite end thereof. Flange 252 has studs 254 contained therein to which an accessory wheel may be attached. The spacing between the studs 254 is the same spacing as studs 244 so that an accessory wheel may be attached by sliding the wheel onto studs 254 and tightening nuts 256. By connecting an accessory wheel in the manner just described additional traction that may be necessary can be provided plus a very rigid structure between the conventional tire and the accessory wheel allows the carrying of exceedingly heavy loads without damage to the tire. Also the wheel accessories as previously described could be used in case of flats to move the automobile to a service station for repairs.
