BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The field of invention relates to buggy apparatus, and more particularly pertains to a new and improved bicycle buggy apparatus wherein the same is readily securable and detachable to an associated bicycle by means of an associated sleeve mounted to the bicycle. 
     2. Description of the Prior Art 
     The use of bicycles in cooperation with rearwardly mounted buggies is well known in the prior art. The apparatus of the prior art has generally been of elaborate or complex organizations to limit the utilization of such apparatus by individuals. The instant invention comprises a bicycle buggy apparatus wherein the same is readily securable and detachable to an associated bicycle wherein the same may be stored during periods of non-use and recoupled during need. For example, U.S. Pat. No 624,678 to Planes sets forth a buggy pivotally mounted at a lowermost forward edge of the buggy to a complex linkage arrangement secured to a rearward axle of the buggy, and to a coupling secured adjacent the seat of the apparatus. The Planes patent is of a relatively complex and elaborate organization limiting utilization. as opposed to that of the instant invention. 
     U.S. Pat. No. 947,945 to Sampson sets forth a further bicycle attachment apparatus wherein the buggy utilizes a forwardly extending loop securable to a rearwardly extending yoke attachable to the framework of the bicycle. The Sampson patent is again typical of the prior art setting forth elaborate structure wherein this instance provides for a continuously positioned obstruction adjacent the rear bicycle wheel, as opposed to &amp;he coupling arrangement of the instant invention. 
     U.S. Pat. No. 559,761 to Armand sets forth a similarly extending yoke formed with a pivotal connection that in turn is securable to a forwardly mounted yoke of the buggy apparatus. The Armand patent again utilizes rearwardly extending projection adjacent the rear tire in securement of an associated buggy to a bicycle. 
     U.S. Pat. No. 609,857 to West sets forth a bicycle attachment apparatus wherein a plurality of forwardly extending links are securable to a framework of a bicycle wherein the West patent in securement to an associated bicycle includes involvement of a labor intensive organization with parallel links securing the buggy to the bicycle, as opposed to a single link mounting arrangement utilized by the instant invention. 
     U.S. Pat. No. 4,306,733 to Cox utilizes a rearwardly extending &#34;V&#34; shaped yoke securable to a rearwardly mounted buggy utilizing a complex link arrangement of enhanced complexity, as opposed to that of the instant invention. 
     As such, it may be appreciated that there continues to be a need for a new and improved bicycle buggy apparatus wherein the same addresses both the problems of selective usage when desired and ease of installation, and in this respect, the present invention substantially fulfills this need.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 5 thereof, a new and improved bicycle buggy apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will noted that the bicycle buggy apparatus 10 essentially comprises a sleeve 11 pivotally mounted about a seat stud 13 integrally secured to and downwardly depending from an associated bicycle seat of the bicycle 12 wherein the seat stud 13 is received fixedly within the framework of the bicycle. The sleeve 11 remains mounted about the seat stud 13 for subsequent coupling and disengagement of the associated buggy of the instant invention. Further, the sleeve 11 enables pivotment of the buggy relative to the seat to enhance maneuvering and ease of use of the apparatus. 
     The buggy 14 of the instant invention is mounted upon an axle 16 rotatably mounting spaced wheels 15. The buggy 14 includes a seat 17 fixedly positioned between side walls 18 of an &#34;L&#34; shaped floor 19 overlying the axle 16 medially to enhance weight distribution of individuals positioned within the buggy 14. A forwardmost edge of the floor 19 has integrally secured thereto a mount 20 with an &#34;S&#34; shaped coupling shaft 21 extending orthogonally outwardly of the mount 20 at a lower end 22 of the coupling shaft 21. An upper end 23 of the coupling shaft 21 is of cylindrical hollow construction to fixedly receive therewithin a securement member 24 formed with a threaded aperture 24a extending therethrough for receiving a bolt 25. The bolt 25 is formed with an elongate threaded shank 26 with an orthogonally and integrally secured head 27 in a large dimension relative to the diameter of the shank 26. The shank 26 includes a shank aperture 28 extending orthogonally and diametrically proximate a lowermost end of the shank 26. 
     The upper end 23 of the coupling shaft 21 includes a plurality of diametrically opposed apertures including an upper coupling shaft aperture 29 and an underlying lower coupling shaft aperture 30 for receiving the locking pin 31 to extend through the upper and lower coupling shafts 29 and 30 respectively and capturing the bolt 25 by means of the shank aperture 28 when the shank 26 extends outwardly of the securement member 24. It is understood that the shank aperture 28 is to be vertically aligned with the upper and lower coupling shaft apertures 29 and 30 to enable positioning of the locking pin 31 therethrough. 
     A separate cylindrical and elongate hollow connecting shaft 32 axially aligned with the upper end 23 of the coupling shaft 21 has fixedly secured at a rearwardmost end 32a of the connecting shaft 32 a positioning sleeve 33 formed with a smooth through-extending sleeve aperture 34 of a diameter substantially equal to the diameter of the threaded shank 26. Accordingly, the threaded shank 26 is positioned slidingly through the sleeve aperture 34 to extend rearwardly and axially to the interior of the upper end 23 of the coupling shaft 21. The forwardmost end of the connecting shaft 32 receives a stub shaft 35 interiorly thereof wherein the stub shaft 35 is integrally secured to the rotatable sleeve 11 at a non-orthogonal angle relative thereto. The stub shaft 35 is formed with a diametrically and orthogonally extending stub shaft aperture 36 to be aligned with an upper and lower connecting shaft aperture 37 and 38 respectively whereupon positioning and alignment of the stub shaft aperture 36 with the connecting shaft apertures, a second lock pin 39 secures the stub shaft 35 to the position sleeve 33 and accordingly the coupling shaft 21. It may be appreciated therefore that to remove the buggy and coupling arrangement, an individual merely removes the second lock pin 39 leaving the rotatable sleeve 11 and the associated stub shaft 35 remaining on the seat stud 13 of the bicycle to effect ready removal and replacement of the buggy relative to the bicycle. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above description and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall 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.
