ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to motor driven dispensers and more particularly pertains to a new compact motor driven dispenser for dispensing caulking and glue material.
2. Description of the Prior Art
The use of motor driven dispensers is known in the prior art. More specifically, motor driven dispensers 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. Nos. 4,306,671; 4,180,187; U.S. Des. Pat. No. 361,247; U.S. Pat. Nos. 5,815,925; 5,503,307; and U.S. Pat. No. 4,024,994.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new compact motor driven dispenser. The inventive device includes a housing having a barrel portion and a handle portion. The barrel portion includes a top wall, a bottom wall, a back wall, a front wall, a first side wall and a second side wall. The front wall has a generally circular shaped opening therein. The top wall has an inner surface having a track mounted thereon. A collapsible push rod is positioned in the housing and has a first end and a second end. The second has a head thereon. The push rod includes a plurality of discrete blocks having a top surface, a bottom surface, a back surface, a front surface and a pair of lateral surfaces. Each of the back surfaces has a saddle integrally attached thereto. Each of the front surfaces has boss thereon. Each of the bosses is positioned in and pivotally coupled to one of the saddles such that the blocks are hingedly coupled to each other. The bottom surfaces each have teeth thereon. The push rod is extendably positioned between the track and the top wall such that the push rod abuts the back wall and the second end of the rod extends toward the front wall of the housing in a generally U-shaped configuration. A motor is positioned in the housing. A plurality of drive gears is mechanically coupled to the motor and in communication with the teeth of the push rod. An actuator selectively turns the motor on or off.
In these respects, the compact motor driven dispenser 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 dispensing caulking and glue material.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of motor driven dispensers now present in the prior art, the present invention provides a new compact motor driven dispenser construction wherein the same can be utilized for dispensing caulking and glue material.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new compact motor driven dispenser apparatus and method which has many of the advantages of the motor driven dispensers mentioned heretofore and many novel features that result in a new compact motor driven dispenser which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art motor driven dispensers, either alone or in any combination thereof.
To attain this, the present invention generally comprises a housing having a barrel portion and a handle portion. The barrel portion includes a top wall, a bottom wall, a back wall, a front wall, a first side wall and a second side wall. The front wall has a generally circular shaped opening therein. The top wall has an inner surface having a track mounted thereon. A collapsible push rod is positioned in the housing and has a first end and a second end. The second has a head thereon. The push rod includes a plurality of discrete blocks having a top surface, a bottom surface, a back surface, a front surface and a pair of lateral surfaces. Each of the back surfaces has a saddle integrally attached thereto. Each of the front surfaces has boss thereon. Each of the bosses is positioned in and pivotally coupled to one of the saddles such that the blocks are hingedly coupled to each other. The bottom surfaces each have teeth thereon. The push rod is extendably positioned between the track and the top wall such that the push rod abuts the back wall and the second end of the rod extends toward the front wall of the housing in a generally U-shaped configuration. A motor is positioned in the housing. A plurality of drive gears is mechanically coupled to the motor and in communication with the teeth of the push rod. An actuator selectively turns the motor on or off.
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 compact motor driven dispenser apparatus and method which has many of the advantages of the motor driven dispensers mentioned heretofore and many novel features that result in a new compact motor driven dispenser which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art motor driven dispensers, either alone or in any combination thereof.
It is another object of the present invention to provide a new compact motor driven dispenser which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new compact motor driven dispenser which is of a durable and reliable construction.
An even further object of the present invention is to provide a new compact motor driven dispenser 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 compact motor driven dispenser economically available to the buying public.
Still yet another object of the present invention is to provide a new compact motor driven dispenser which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming so
