ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to simulated toys and more particularly pertains to a new weight transferring sled toy for simulating a weight transfer sled used in truck and tractor pulls.
2. Description of the Prior Art
The use of simulated toys is known in the prior art. More specifically, simulated toys 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. No. 4,571,211; U.S. Pat. No. 4,475,305; U.S. Pat. No. 4,296,840; U.S. Pat. No. 4,354,309; U.S. Pat. No. 4,615,223; and U.S. Pat. No. Des. 393,233.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new weight transferring sled toy. The inventive device includes a main body portion that has a main body base and a pair of tracks that extend upward from the main body base. A pair of wheels are coupled to a rear portion of the main body portion. An axle extends between the wheels and is coupled to the rear portion of the main body portion. An axle gear is coupled to a medial portion of the axle. A bar extends between a forward portion of the tracks. A drive chain extends between the bar and the axle gear such that rotation of the axle gear rotates the drive chain. A weight sled is positionable on the tracks. The weight sled has a hook member for engaging the drive chain whereby the weight sled is moved along the tracks when the wheels rotate and the hook member is engaged to the drive chain.
In these respects, the weight transferring sled toy 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 simulating a weight transfer sled used in truck and tractor pulls.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of simulated toys now present in the prior art, the present invention provides a new weight transferring sled toy construction wherein the same can be utilized for simulating a weight transfer sled used in truck and tractor pulls.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new weight transferring sled toy apparatus and method which has many of the advantages of the simulated toys mentioned heretofore and many novel features that result in a new weight transferring sled toy which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art simulated toys, either alone or in any combination thereof.
To attain this, the present invention generally comprises a main body portion that has a main body base and a pair of tracks that extend upward from the main body base. A pair of wheels are coupled to a rear portion of the main body portion. An axle extends between the wheels and is coupled to the rear portion of the main body portion. An axle gear is coupled to a medial portion of the axle. A bar extends between a forward portion of the tracks. A drive chain extends between the bar and the axle gear such that rotation of the axle gear rotates the drive chain. A weight sled is positionable on the tracks. The weight sled has a hook member for engaging the drive chain whereby the weight sled is moved along the tracks when the wheels rotate and the hook member is engaged to the drive chain.
There has thus been out lined, 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 weight transferring sled toy apparatus and method which has many of the advantages of the simulated toys mentioned heretofore and many novel features that result in a new weight transferring sled toy which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art simulated toys, either alone or in any combination thereof.
It is another object of the present invention to provide a new weight transferring sled toy that may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new weight transferring sled toy that is of a durable and reliable construction.
An even further object of the present invention is to provide a new weight transferring sled toy 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 weight transferring sled toy economically available to the buying public.
Still yet another object of the present invention is to provide a new weight transferring sled toy 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 weight transferring sled toy for simulating a weight transfer sled used in truck and tractor pulls.
Yet another object of the present invention is to provide a new weight transferring sled toy which includes a main body portion that has a main body base and a pair of tracks that extend upward from the main body base. A pair of wheels are coupled to a rear portion of the main body portion. An axle extends between the wheels and is coupled to the rear portion of the main body portion. An axle gear is coupled to a medial portion of the axle. A bar extends between a forward portion of the tracks. A drive chain extends between the bar and the axle gear such that rotation of the axle gear rotates the drive chain. A weight sled is positionable on the tracks. The weight sled has a hook member for engaging the drive chain whereby the weight sled is moved along the tracks when the wheels rotate and the hook member is engaged to the drive chain.
Still yet another object of the present invention is to provide a new weigh
