ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to bicycle devices and more particularly pertains to a new wheelchair and bicycle combination assembly for pushing a wheelchair while riding a bike.
2 Description of the Prior Art
The use of bicycle devices is known in the prior art. More specifically, bicycle devices 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 includes U.S. Pat. Nos. 3,429,584; 4,402,502; 4,705,284; U.S. Pat. No. Des. 356,530; U.S. Pat. Nos. 4,373,740; and 5,273,304.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new wheelchair and bicycle combination assembly. The inventive device includes a bicycle frame. A seat assembly slidably mounts to the bicycle frame. A gear assembly comprises at least a first gear and a second gear. The first gear is rotatably coupled to a front portion of the frame. The second gear is rotatably coupled to a back portion of the frame. A bike chain extends around and is in communication with teeth on the first and second gears. A crank axle extends through the first gear. The crank axle has a pair of ends. Each of a pair of pedals is rotatably coupled to one of the ends of the crank axle. A bike wheel is securely attached to the second gear. A wheelchair includes a seat portion. A back rest is securely coupled to and extends upwardly from a back edge of the seat portion. A pair of front wheels and a pair of rear wheels are rotatably coupled to the seat portion. An axle extends between the back wheels. Each of a pair of handles is coupled to and extends upwardly away from a top edge of the back rest. A coupling means removably attaches the bicycle frame to the axle of the wheelchair.
In these respects, the wheelchair and bicycle combination assembly 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 pushing a wheelchair while riding a bike.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of bicycle devices now present in the prior art, the present invention provides a new wheelchair and bicycle combination assembly construction wherein the same can be utilized for pushing a wheelchair while riding a bike.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new wheelchair and bicycle combination assembly apparatus and method which has many of the advantages of the bicycle devices mentioned heretofore and many novel features that result in a new wheelchair and bicycle combination assembly which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art bicycle devices, either alone or in any combination thereof.
To attain this, the present invention generally comprises a bicycle frame. A seat assembly slidably mounts to the bicycle frame. A gear assembly comprises at least a first gear and a second gear. The first gear is rotatably coupled to a front portion of the frame. The second gear is rotatably coupled to a back portion of the frame. A bike chain extends around and is in communication with teeth on the first and second gears. A crank axle extends through the first gear. The crank axle has a pair of ends. Each of a pair of pedals is rotatably coupled to one of the ends of the crank axle. A bike wheel is securely attached to the second gear. A wheelchair includes a seat portion. A back rest is securely coupled to and extends upwardly from a back edge of the seat portion. A pair of front wheels and a pair of rear wheels are rotatably coupled to the seat portion. An axle extends between the back wheels. Each of a pair of handles is coupled to and extends upwardly away from a top edge of the back rest. A coupling means removably attaches the bicycle frame to the axle of the wheelchair.
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. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new wheelchair and bicycle combination assembly apparatus and method which has many of the advantages of the bicycle devices mentioned heretofore and many novel features that result in a new wheelchair and bicycle combination assembly which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art bicycle devices, either alone or in any combination thereof.
It is another object of the present invention to provide a new wheelchair and bicycle combination assembly which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new wheelchair and bicycle combination assembly which is of a durable and reliable construction.
An even further object of the present invention is to provide a new wheelchair and bicycle combination assembly which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such wheelchair and bicycle combination assembly economically available to the buying public.
Still yet another object of the present invention is to provide a new wheelchair and bicycle combination assembly which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Still another object of the present invention is to provide a new wheelchair and bicycle combination assembly for pushing a wheelchair while riding a bike.
Yet another object of the present invention is to provide a new wheelchair and bicycle combination assembly which includes a bicycle frame. A seat assembly slidably mounts to the bicycle frame. A gear assembly comprises at least a first gear and a seco
