ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a system for testing trailer light systems and more particularly pertains to testing the lights of a trailer whereby the device is supported in a hands free manner.
2. Description of the Prior Art
The use of trailer light tester systems of known designs and configurations is known in the prior art. More specifically, tractor/trailer light tester systems of known designs and configurations heretofore devised and utilized for the purpose of testing tractor/trailer light systems through known methods and apparatuses are known to consist basically of familiar, expected, and obvious configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 4,547,722 to Sarlo discloses a Test Panel For Tractor And trailer Lights. U.S. Pat. No. 4,884,032 to LaPensee discloses an Trailer/Tractor Light System. U.S. Pat. No. 5,416,421to Doland, Sr. et al. discloses a trailer Lamp Testing and Lamp Storage Apparatus. U.S. Pat. No. 5,086,277 to Hammerly discloses an Apparatus And Method For Performing Diagnostic Tests on The Electrical Systems Of Recreational Vehicles And The Like. U.S. Pat. No. 3,737,767 to Slutsky discloses an Trailer Testing System. Lastly, U.S. Pat. No. 3,663,939 to Olsson discloses an Combination Test Box And Battery Charger.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe system for testing trailer light systems as disclosed herein.
In this respect, the system for testing trailer light systems according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of testing the lights of a trailer while the testing device is supportable from the glad hand normally associated with a trailer.
Therefore, it can be appreciated that there exists a continuing need for a system for testing trailer light systems which can be used for system for testing trailer light systems for testing the lights of a trailer while the testing device is supportable from the glad hand normally associated with a trailer. In this regard, the present invention substantially fulfills this need.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of system for testing trailer light systems of known designs and configurations now present in the prior art, the present invention provides an improved system for testing trailer light systems. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved system for testing trailer light systems and method which has all the advantages of the prior art and none of the disadvantages.
To attain this, the present invention essentially comprises a new and improved system for testing trailer light systems interconnected by a cable wherein the trailer has a gladhand. The system includes a housing having a front control panel, a pair of battery terminals connected to said housing for connecting it to a battery and a cable connected to the housing having a connector which can be connected to an electrical receptacle of a trailer. Further, a plurality of switches are connected to the battery and the connector for testing various electrical circuits in the trailer. Additionally, a support rod is provided for engaging a convention glad hand thereby supporting the device in a hands free manner when in use.
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, of course, 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 descriptions 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 system for testing trailer light systems which has all of the advantages of the prior systems for testing trailer light systems of known designs and configurations and none of the disadvantages.
It is another object of the present invention to provide a new and improved system for trailer light systems which may be easily and efficiently manufactured and marketed.
It is further object of the present invention to provide a new and improved system for trailer light systems which is of durable and reliable constructions.
An even further object of the present invention is to provide a new and improved light testing system 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 system for testing trailer light systems economically available to the buying public.
Lastly, it is an object of the present invention to provide a new and improved system for testing trailer light systems interconnected by a cable wherein the trailer has a gladhand whereby the system includes a housing having a front control panel, a pair of battery terminals, and a cable connected to the housing having a connector which can be connected to an electrical receptacle of a trailer whereby a support rod is provided for engaging a convention glad hand thereby supporting the device in a hands free manner when in use.
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 had to the accompanying drawings and descriptive matter in which there is illustrated preferred embodiments of the invention.
