BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to grease guns and more specifically it relates to a grease gun applicator system for making it easier to use a battery powered grease gun by freeing up one hand while greasing.

2. Description of the Related Art

Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.

Grease guns have been in use for years. Typically, manual powered grease guns must be pumped with one hand and the hose must be directed with the other hand onto the area that is to be greased. Battery powered grease guns do not require pumping. Instead a trigger is pressed, while holding the grease gun with one hand, and the hose is directed with the other hand onto the area that is to be greased.

While trying to grease areas that are hard to reach or require difficult balancing, it is often difficult to properly apply grease using a grease gun. This difficulty arises because the user must use both his/her hands to operate the grease gun, which leaves no hands for stabilizing the individual.

While these devices may be suitable for the particular purpose to which they address, they are not as suitable for making it easier to use a battery powered grease gun by freeing up one hand while greasing. When climbing ladders or reaching hard to get to places, a grease gun is very difficult to use. Generally, a hose on a grease gun is not very long, forcing the user to get very close to area needed to be greased. Also, typical grease guns do not allow the user to comfortably reach a hard to get to area while balancing one self with one of their hands.

In these respects, the grease gun applicator system 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 making it easier to use a battery powered grease gun by freeing up one hand while greasing.

BRIEF SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of grease guns now present in the prior art, the present invention provides a new grease gun applicator system construction wherein the same can be utilized for making it easier to use a battery powered grease gun by freeing up one hand while greasing.

The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new grease gun applicator system that has many of the advantages of the grease guns mentioned heretofore and many novel features that result in a new grease gun applicator system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art grease guns, either alone or in any combination thereof.

To attain this, the present invention generally comprises a powered grease gun, a dispensing hose extending from the powered grease gun, a dispensing nozzle attached to a distal end of the dispensing hose and a control switch attached to or adjacent to the dispensing nozzle to control the powered grease gun. A sling is preferably attached to the powered grease gun for allowing easy transportation of the powered grease gun.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof 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 that will form the subject matter of the claims appended hereto.

DETAILED DESCRIPTION OF THE INVENTION

A. Overview

Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIGS. 1 through 8 illustrate a grease gun applicator system 10, which comprises a powered grease gun 20, a dispensing hose 32 extending from the powered grease gun 20, a dispensing nozzle 34 attached to a distal end of the dispensing hose 32 and a control switch 70 attached to or adjacent to the dispensing nozzle 34 to control the powered grease gun 20.

B. Powered Grease Gun

FIGS. 1 through 5 illustrate an exemplary powered grease gun 20. The powered grease gun 20 may be comprised of any grease gun that is electrically powered by a power source 14 (e.g. battery, wall outlet). The exemplary powered grease gun 20 preferably has a housing 21, a handle 22 extending from the housing 21 (typically a storage location for a battery), and a receiver unit 30 connected to the housing 21. The receiver unit 30 receives a grease cartridge and provides the grease to the pump which is mechanically connected to the motor 26 within the powered grease gun 20. The pump provides pressurized grease to the dispensing hose 32 that is fluidly connected to the pump.

The dispensing hose 32 is comprised of a desirable length and fluidly extends from the powered grease gun 20 for dispensing the pressurized grease. The dispensing hose 32 is preferably comprised of a flexible tubular structure capable of transporting the pressurized grease to a dispensing nozzle 34 attached to the distal end of the dispensing hose 32. The dispensing nozzle 34 is formed to fit upon a grease fitting 12 (referred to commonly as a grease zerk).

A holder member 23 is preferably attached to the housing 21 of the powered grease gun 20 for catchably receiving the dispensing hose 32 when not in use as best illustrated in FIG. 3 of the drawings. The holder member 23 is preferably comprised of a clip structure as illustrated in FIG. 4 of the drawings.

As shown in FIGS. 2 through 5 of the drawings, a locking member 40 is provided for surrounding a handle 22 of the powered grease gun 20 and engaging a main switch 24 (e.g. trigger) of the powered grease gun 20 thereby maintaining the main switch 24 in a closed state. The locking member 40 is preferably comprised of a plastic zip tie, however the locking member 40 may be comprised of other structures capable of retaining the main switch 24 in a closed state (e.g. tape).

C. Control Switch

The control switch 70 is attached to or adjacent to the dispensing nozzle 34 so that when the user is retaining the dispensing nozzle 34 upon a grease fitting 12 they may simultaneously close the control switch 70 as shown in FIG. 1 of the drawings. The control switch 70 may be attached to or integrally formed within the dispensing nozzle 34 and/or dispensing hose 32. The control switch 70 is preferably a rocker switch, however other types of switches may be utilized.

The control switch 70 may be electrically connected to the powered grease gun 20 via a control cable 72 that runs the length of the dispensing hose 32 (FIG. 5) or the control switch 70 may include a transmitter 74 for transmitting a signal to a receiver 76 electrically connected to the powered grease gun 20.

If the control switch 70 is in communication with the powered grease gun 20 via a radio signal, an override switch 28 is preferably electrically positioned between said motor 26 and said main switch 24 of the powered grease gun 20 as shown in FIG. 7 of the drawings. The override switch 28 is opened and closed based upon the same state of the control switch 70 to allow for remote control of the operation of the powered grease gun 20 by the control switch 70. If a control cable 72 is electrically connected between the control switch 70 and the powered grease gun 20, the control switch 70 is thereby electrically connected between the main switch 24 and the motor 26 via the control cable 72.

D. Sling

An elongated sling 50 is preferably attached to the powered grease gun 20 for supporting the powered grease gun 20 upon the shoulder of the user during use as shown in FIG. 1 of the drawings. The elongated sling 50 is preferably adjustable in length to accommodate various sizes of users.

A pair of connecting members 60 are attached to the powered grease gun 20 and a pair of catch members 52 extend from distal ends of the sling 50 for removably attaching to the pair of connecting members 60 as best shown in FIGS. 2 through 4 of the drawings. The pair of connecting members 60 are preferably threadably attached to threaded openings within the housing 21 of the powered grease gun 20 as best illustrated in FIG. 4 of the drawings.

Alternative as shown in FIGS. 5 and 6 of the drawings, the sling 50 includes a first strap 54 and a second strap 56 extending substantially transversely with respect to the sling 50. The straps 54, 56 are sufficient in length to surround the handle 22 of the powered grease gun 20 and connect to themselves with fasteners as shown in FIG. 5 of the drawings. The first strap 54 and the second strap 56 each preferably include hook and loop fasteners 58 at their respective distal portions for removably securing about a receiver unit 30 of the powered grease gun 20. The straps 54, 56 are preferably substantially centered upon the sling 50 as further shown in FIG. 6 of the drawings.

E. Operation of Invention

In use, the user straps the sling 50 over their shoulder to easily transport the powered grease gun 20 as shown in FIG. 1 of the drawings. It can be appreciated that the powered grease gun 20 may also be simply laid upon the ground while the user reaches beneath an object for greasing. The user then positions the dispensing nozzle 34 in a fluidly connected manner to the grease fitting 12 on equipment or other object to be greased. With the same hand, the user then manipulates the control switch 70 to activate the motor 26 of the powered grease gun 20 which then dispenses the pressurized grease to the dispensing nozzle 34. The user maintains the control switch 70 in the closed state until the desired amount of grease has been dispensed into the grease fitting 12, after which the user opens the control switch 70 which terminates the motor 26 of the powered grease gun 20. The user then removes the dispensing nozzle 34 and may continue to use the present invention with respect to additional grease fittings 12.
