     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to the field of motorized chairs, more specifically, an accessory that supports a leg of an end user on a motorized chair. 
     SUMMARY OF INVENTION 
     The leg support for a motorized chair is an accessory that is adapted to be mounted onto a motorized chair in order to support a leg of an end user that is riding said motorized chair. The leg support includes a first armature that is adapted to be affixed to and extend upwardly from a motorized chair floor surface. The first armature may employ the use of at least one mounting bracket to rigidly affix the first armature to the motorized chair. The first armature extends upwardly and includes a bend that designates a second armature portion. A leg rest is selectively bolted to the second armature portion. The leg rest is supported at a horizontal orientation with respect to the motorized chair. The leg rest includes at least one leg rest bracket to secure the leg rest to the second armature portion. The at least one leg rest bracket is selectively detached from the second armature portion such that the leg rest may be reversed in order to adaptively support either leg of the end user that is riding the motorized chair. 
     These together with additional objects, features and advantages of the leg support for a motorized chair will be readily apparent to those of ordinary skill in the art upon reading the following detailed description of the presently preferred, but nonetheless illustrative, embodiments when taken in conjunction with the accompanying drawings. 
     In this respect, before explaining the current embodiments of the leg support for a motorized chair in detail, it is to be understood that the leg support for a motorized chair is not limited in its applications to the details of construction and arrangements of the components set forth in the following description or illustration. Those skilled in the art will appreciate that the concept of this disclosure may be readily utilized as a basis for the design of other structures, methods, and systems for carrying out the several purposes of the leg support for a motorized chair. 
     It is therefore important that the claims be regarded as including such equivalent construction insofar as they do not depart from the spirit and scope of the leg support for a motorized chair. It is also to be understood that the phraseology and terminology employed herein are for purposes of description and should not be regarded as limiting.

As used herein, the word “exemplary” or “illustrative” means “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” or “illustrative” is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to practice the disclosure and are not intended to limit the scope of the appended claims. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. 
     Detailed reference will now be made to a multiple potential embodiments of the disclosure, which are illustrated in  FIGS. 1 through 5 . 
     The leg support for a motorized chair  100  (hereinafter invention) comprises a first armature  101  that is a pole of an undefined length. The first armature  101  is vertically oriented, and further defined with a bend  102 . The bend  102  designates a second armature portion  103 . The bend  102  is a 90-degree bend in the first armature  101 , and the second armature portion  103  extends from the bend  102 . 
     The second armature portion  103  is horizontally oriented, and further defined with a second length  104 . The second length is not less than 1 inch, but not greater than 3 feet. The first armature  101  extends a first height  105 . The first height  105  is not less than 1 inch, but not greater than 3 feet. The first armature is further defined with a first distal end  106 . The first distal end  106  is where the first armature  101  adaptively engages a motorized chair  200 . More specifically, the motorized chair  200  is further defined with a motorized chair floor surface  201  where a rider  300  places his or her feet  301  thereon. The first distal end  106  is adapted to interface with the motorized chair floor surface  201 . 
     The invention  100  includes a leg rest  107 . The leg rest  107  is able to be secured to the second armature portion  103 . Moreover, both the leg rest  107  and the second armature portion  103  are horizontally oriented with respect to the motorized chair floor surface  201 . The leg rest  107  is further defined with a top rest surface  108  that is concave. The top rest surface  108  is adapted to receive a leg  302  of the end user  300  thereon. The leg rest  107  has an overall shape that resembles an elongated circle. The leg rest  107  is made of a soft foam material. The leg rest  107  is also further defined with a bottom rest surface  109 . The bottom rest surface  109  is generally flat. 
     At least one leg rest bracket  110  is provided with the invention  100 . The at least one leg rest bracket  110  secures between the bottom rest surface  109  of the leg rest  107  and the second armature portion  103 . The at least one leg rest bracket  110  is responsible for supporting the leg rest  107  at a horizontal orientation with respect to the motorized chair floor surface  201  of the motorized chair  200 . 
     The at least one leg rest bracket  110  is further defined with a flat portion  111  affixed to a semi-circular bend portion  112 . The semi-circular bend portion  112  wraps over top of the second armature portion  103 , and a bolt member  113  extends there through. The bolt member  113  is oriented downwardly, and extends across bolt holes  114  provided on the second armature portion  103 . The bolt member  113  includes a nut  115  to secure the bolt member  113  to the second armature portion  103 . 
     The bottom rest surface  109  of the leg rest  107  includes leg bolts  116  that extend downwardly, and extend across the flat portion  111  of the at least one leg rest bracket  110 . Leg nuts  117  secure the leg bolts  116  in place with respect to the flat portion  111  of the at least one leg rest bracket  110 . 
     The first armature  101  includes at least one chair bracket  118  to secure the first armature  101  to the motorized chair  200 . The at least one chair bracket  118  is adapted to mount onto the motorized chair floor surface  201  of the motorized chair  200 . The at least one chair bracket  118  attach to the first armature  101  adjacent to the first distal end  106 . The at least one chair bracket  118  is an angled bracket that forms a 90-degree bend so as to fasten to the first armature  101  as well as adaptively to the motorized chair  200 . 
     The first armature  101 , the at least one chair bracket  118 , and the at least one leg rest bracket  110  are made of a material comprising a plastic, wood, metal, carbon fiber composite. The leg rest  107  may be made of a soft foam, a wood, a metal, a plastic, a carbon fiber composite. Moreover, the leg rest  107  may be made with a Visco-elastic foam that is encased within an outer casing. 
     With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention described above and in  FIGS. 1 through 5 , 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 invention. 
     It shall be noted that those skilled in the art will readily recognize numerous adaptations and modifications which can be made to the various embodiments of the present invention which will result in an improved invention, yet all of which will fall within the spirit and scope of the present invention as defined in the following claims. Accordingly, the invention is to be limited only by the scope of the following claims and their equivalents.
