Rail engaging toilet paper holder
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to roll holders and more particularly pertains to a rail engaging toilet paper holder for rotatably supporting a roll of toilet paper relative to a rail of a supporting structure. 
     2. Description of the Prior Art 
     The use of roll holders is known in the prior art. More specifically, roll holders heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     Known prior art roll holders include U.S. Pat. Nos. 4,513,932; 4,218,028; 4,106,617; 3,792,822; and U.S. Pat. No. 3,482,796. 
     While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a rail engaging toilet paper holder for rotatably supporting a roll of toilet paper relative to a rail of a supporting structure which includes a mounting assembly that can be snapped over a cylindrical rail of the supporting structure, and a supporting assembly extending from the mounting assembly for engaging and rotatably supporting a roll of toilet paper. 
     In these respects, the rail engaging toilet paper holder according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of rotatably supporting a roll of toilet paper. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of roll holders now present in the prior art, the present invention provides a new rail engaging toilet paper holder construction wherein the same can be utilized for rotatably supporting a roll of toilet paper. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new rail engaging toilet paper holder apparatus and method which has many of the advantages of the roll holders mentioned heretofore and many novel features that result in a rail engaging toilet paper holder which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art roll holders, either alone or in any combination thereof. 
     To attain this, the present invention generally comprises a holder for rotatably supporting a roll of toilet paper relative to a rail of a supporting structure. The inventive device includes a mounting assembly which can be snapped over a cylindrical rail of a wheelchair or portable toilet structure. A supporting assembly extends from the mounting assembly for engaging and rotatably supporting a roll of toilet paper relative to the supporting structure. 
     There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 3-8 thereof, a new rail engaging toilet paper holder embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     Turning initially to FIGS. 1 and 2 wherein prior art roll holders are illustrated, it can be shown that the prior art teaches a roll holder securable to a flat wall surface, as shown in FIG. 1, or a roll holder having a complicated clamp structure for securing the roll holder to an elongated member, as shown in FIG. 2. 
     Turning now to FIGS. 3 through 8 wherein the rail engaging toilet paper 10 according to present invention is illustrated in detail, it can be shown that the toilet paper holder substantially departs from the designs and concepts of the prior art and includes a mounting means 12 for engaging a rail 14 of a supporting structure 16, such as the portable toilet structure illustrated in FIG. 3 of the drawings. A supporting means 18 is coupled to the mounting means 12 and extends outwardly therefrom to rotatably support a toilet paper roll 20 as shown in FIG. 4 for example. Thus, the present invention 10 can be utilized to rotatably mount the toilet paper roll 20 relative to a supporting structure 16 such as a portable toilet or wheelchair. 
     As best illustrated in FIGS. 4 through 6, it can be shown that the mounting means 12 according to the present invention 10 preferably comprises a first mounting loop 22 of arcuate configuration spaced from a second mounting loop 24 of similar construction. A transverse leg 26 extends between the mounting loops 22 and 24 to maintain the mounting loops in a spaced and parallel orientation. The mounting loops 22 and 24 are operable to be snapped into engagement with the rail 14 of the supporting structure 16 to secure the mounting means 12 thereto. Preferably, and as shown in FIGS. 7 and 8, the mounting means 12 additionally comprises means for providing friction in the form of a friction strip 28 extending along an interior surface of the transverse leg 26. The friction strip 28 is preferably comprised of a substantially resilient material so as to promote frictional engagement between the friction strip 28 and the rail 14 to preclude a rotation of the mounting means 12 relative to the rail. 
     As shown in FIGS. 4 and 6, the supporting means 18 according to the present invention 10 extends from the mounting means 12 so as to project laterally from the supporting structure 16 to which the mounting means is attached. The supporting means 18 preferably comprises a first projecting leg 30 secured to the first mounting loop 22 and terminating at an outer distal end thereof. A first supporting leg 32 is coupled to the outer distal end of the first projecting leg 30 and oriented so as to extend substantially orthogonally therefrom. Similarly, a second projecting leg 34 is fixedly secured to the mounting loop 24 and extends outwardly therefrom to terminate in an outer distal end, with a second supporting leg 36 being coupled to the outer distal end of the second projecting leg 34 and oriented so as to extend substantially orthogonally therefrom. The first and second supporting legs 32 and 36 are oriented so as to project towards one another, as shown in FIG. 4, such that they can be extended into an interior of a toilet paper roll 20 positioned between the projecting legs 30 and 34. 
     The mounting means 12 and the supporting means 18 are preferably integrally molded from a resilient plastic material or the like which permits an outward biasing of the projecting legs 30 and 34 to facilitate placement of the toilet paper roll 20 therebetween. Further, constructing the mounting means 12 of the resilient plastic material permits a deformation of the mounting loops 22 and 24 during engagement thereto relative to the rail 14 of the supporting structure 16, whereby the resilient nature of the plastic material results in a contraction of the mounting loops subsequent to placement over the rail 14 which further enhances securement of the mounting means 12 to the rail. 
     In use, the rail engaging toilet paper holder according to the present invention can be easily engaged to the rail 14 of a supporting structure 16 so as to rotatably support a toilet paper roll 20 relative to an individual. The supporting structure 16 may comprise a wheelchair or a portable toilet, for example. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
