ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to scaffold lifts and more particularly pertains to a new scaffold mountable hoist platform for conveying of materials to different levels of a scaffold.
2. Description of the Prior Art
The use of scaffold lifts is known in the prior art. More specifically, scaffold lifts 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. 5,205,379; U.S. Pat. No. 3,951,236; U.S. Pat. No. 5,152,369; U.S. Pat. No. 3,313,376; U.S. Pat. No. 4,938,310; and U.S. Pat. No. Des. 265,425.
In these respects, the scaffold mountable hoist platform 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 conveying of materials to different levels of a scaffold.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of scaffold lifts now present in the prior art, the present invention provides a new scaffold mountable hoist platform construction wherein the same can be utilized for conveying of materials to different levels of a scaffold.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new scaffold mountable hoist platform apparatus and method which has many of the advantages of the scaffold lifts mentioned heretofore and many novel features that result in a new scaffold mountable hoist platform which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art scaffold lifts, either alone or in any combination thereof.
To attain this, the present invention generally comprises a frame having a rear frame member, a deck support member. The deck support member is orthogonally extending from the rear frame member is for supporting a deck. A plurality of rear vertical guides are positioned proximate the frame. A plurality of stanchion guide assemblies are mounted to the frame such that the stanchion guide assemblies are adapted for releasably engaging the stanchions. Each of the stanchion guide assemblies have a bearing plate and a plurality of bearings. The bearing plate has a plurality of apertures therethrough. The bearings are coupled to the bearing plate such that the bearings extend through the apertures for rollably engaging the stanchions. A lifting means is coupled to the frame for raising and lowering the frame along the stanchions of the scaffold.
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.
It is therefore an object of the present invention to provide a new scaffold mountable hoist platform apparatus and method which has many of the advantages of the scaffold lifts mentioned heretofore and many novel features that result in a new scaffold mountable hoist platform which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art scaffold lifts, either alone or in any combination thereof.
It is another object of the present invention to provide a new scaffold mountable hoist platform which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new scaffold mountable hoist platform which is of a durable and reliable construction.
An even further object of the present invention is to provide a new scaffold mountable hoist platform 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 scaffold mountable hoist platform economically available to the buying public.
Still yet another object of the present invention is to provide a new scaffold mountable hoist platform 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 scaffold mountable hoist platform for conveying of materials to different levels of a scaffold.
Still yet another object of the present invention is to provide a new scaffold mountable hoist platform that provides safe means of reducing the amount of work required of a person to convey the materials up the scaffold.
Even still another object of the present invention is to provide a new scaffold mountable hoist platform that reduces the amount of work time lost in transporting the materials up the scaffold.
These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be made to the accompanying drawings and descriptive matter in which there are illustrated preferred embodiments of the invention.
