ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to dollies and more particularly pertains to a new directional braking transport assembly for safely transporting heavy loads up and down steep inclines.
2. Description of the Prior Art
The use of dollies is known in the prior art. More specifically, dollies 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. 5,388,672; U.S. Pat. No. 4,867,282; U.S. Pat. No. 4,934,490; U.S. Pat. No. 5,277,436; U.S. Patent Des. 301,157; and U.S. Pat. No. 5,197,750.
In these respects, the directional braking transport 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 transporting heavy loads up and down steep inclines.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of dollies now present in the prior art, the present invention provides a new directional braking transport assembly construction wherein the same can be utilized for transporting heavy loads up and down steep inclines.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new directional braking transport assembly apparatus and method which has many of the advantages of the dollies mentioned heretofore and many novel features that result in a new directional braking transport assembly which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art dollies, either alone or in any combination thereof.
To attain this, the present invention generally comprises a frame including a substantially planar rectangular bottom plate, a pair of handle posts coupled to a rear edge of the plate adjacent to opposite side edges thereof and extending upwardly therefrom in perpendicular relationship therewith, an axle perpendicularly coupled between lower portions of the posts of the frame adjacent to and spaced from the bottom plate, wherein ends of the axle extend past the handle posts; and a pair of wheel assemblies each including a fixed housing having a substantially planar circular inner plate fixedly coupled to the axle between one of the posts and one of the ends of the axle, an annular peripheral lip coupled to a periphery of the inner plate and extending outwardly therefrom for defining an interior space, and a rectangular cut out formed in the peripheral lip adjacent to and to the rear of an apex thereof, a wheel including a substantially planar circular outer plate with a diameter equal to that of the inner plate of the housing and rotatably coupled to one of the ends of the axle, a side wall coupled to a periphery of the outer plate and extending inwardly therefrom for rotatably engaging the peripheral lip of the housing, a tire coupled to an outer surface of the side wall with a diameter greater than that of the housing, and a plurality of teeth formed in an inner surface of the side wall, and a pawl assembly including a lever with a substantially planar rectangular inboard portion hingably coupled at a central extent thereof about a horizontal axis within the cut out formed in the peripheral lip of the housing and a substantially planar rectangular outboard portion extending outwardly and downwardly with respect to the inboard portion for defining an obtuse angle therewith, an arm coupled at a first end thereof to an inboard end of the inboard portion of the lever and extending into the wheel in parallel relationship with the axle of the frame, and a pawl coupled at a central extent thereof to a second end of the arm, the pawl having a pair of beveled ends for engaging the teeth of the wheel when the lever is in a first orientation to allow only forward movement of the wheel of the wheel assembly, engaging the teeth of the wheel when the lever is in a second orientation to allow only rearward movement of the wheel of the wheel assembly, and disengaging the teeth of the wheel when the lever is in an intermediate third orientation to allow both forward and rearward movement of the wheel of the wheel assembly.
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 directional braking transport assembly apparatus and method which has many of the advantages of the dollies mentioned heretofore and many novel features that result in a new directional braking transport assembly which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art dollies, either alone or in any combination thereof.
It is another object of the present invention to provide a new directional braking transport assembly which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new directional braking transport assembly which is of a durable and reliable construction.
An even further object of the present invention is to provide a new directional braking transport 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 directional braking transport assembly economically available to the buying public.
Still yet another object of the present invention is to provide a new directional braking transport 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 directional braking transport assembly for transporting heavy loads up and down steep inclines.
Even still another object of the present invention is to provide a new directiona
