ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to devices for disassembling u-joints and more particularly pertains to a new device for disassembling a universal joint for removal of the connecting member of a universal joint with minimal effort.
2. Description of the Prior Art
The use of devices for disassembling u-joints is known in the prior art. More specifically, devices for disassembling u-joints 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. 5,050,285; U.S. Pat. No. 4,977,660; U.S. Pat. No. 3,230,617; U.S. Pat. No. 4,249,296; U.S. Pat. No. 3,786,544; and U.S. Pat. No. 4,343,075.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new device for disassembling a universal joint. The inventive device includes the universal joint having a generally cross shaped connecting member with two pairs of ends. Each of the ends has a cap thereon. The connecting member connects two arms. Each of the arms has an end that is U-shaped. Each portion of said U-shaped end has a bore therein for receiving an end of the connecting member. The device has a frame. The frame has a top wall, a bottom wall, a first side wall and a second side wall. A bore for insertion of a cap of the connecting member is in the second side wall. A pressing assembly urges the ends of the arms against the second side wall of the frame. The pressing assembly has a pump portion and an extendable arm such that the extendable arm extends away from the pump portion. The pump portion is mounted to an interior surface of the first side wall such that the extendable arm is extendable towards the second side wall.
In these respects, the device for disassembling a universal joint 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 removal of the connecting member of a universal joint with minimal effort.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of devices for disassembling u-joints now present in the prior art, the present invention provides a new device for disassembling a universal joint construction wherein the same can be utilized for removal of the connecting member of a universal joint with minimal effort.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new device for disassembling a universal joint apparatus and method which has many of the advantages of the devices for disassembling u-joints mentioned heretofore and many novel features that result in a new device for disassembling a universal joint which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art devices for disassembling u-joints, either alone or in any combination thereof.
To attain this, the present invention generally comprises the universal joint having a generally cross shaped connecting member with two pairs of ends. Each of the ends has a cap thereon. The connecting member connects two arms. Each of the arms has an end that is U-shaped. Each portion of said U-shaped end has a bore therein for receiving an end of the connecting member. The device has a frame. The frame has a top wall, a bottom wall, a first side wall and a second side wall. A bore for insertion of a cap of the connecting member is in the second side wall. A pressing assembly urges the ends of the arms against the second side wall of the frame. The pressing assembly has a pump portion and an extendable arm such that the extendable arm extends away from the pump portion. The pump portion is mounted to an interior surface of the first side wall such that the extendable arm is extendable towards the second side wall.
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 device for disassembling a universal joint apparatus and method which has many of the advantages of the devices for disassembling u-joints mentioned heretofore and many novel features that result in a new device for disassembling a universal joint which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art devices for disassembling u-joints, either alone or in any combination thereof.
It is another object of the present invention to provide a new device for disassembling a universal joint which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new device for disassembling a universal joint which is of a durable and reliable construction.
An even further object of the present invention is to provide a new device for disassembling a universal joint 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 device for disassembling a universal joint economically available to the buying public.
Still yet another object of the present invention is to provide a new device for disassembling a universal joint 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 device for disassembling a universal joint for removal of the connecting member of a universal joint with minimal effort.
Yet another object of the present invention is to provide a new device for disassembling a universal joint which includes the universal joint having a generally cross shaped connecting member with two pairs of ends. Each of the ends has a cap thereon. The connecting member co
