Illumination for grease gun nozzles

Abstract

An adapter to provide illumination at a grease gun nozzle and a method of attaching the adapter to a grease gun is presented. The adapter comprises a body having a threaded aperture, a non-threaded aperture, and a light source secured within the non-threaded aperture such that the distal end of a dispensing hose of a grease gun extends out of the adapter once the adapter is coupled to the dispensing hose. To attach the adapter to a dispensing hose of a grease gun, one must first unscrew the dispensing nozzle from the distal end of the dispensing hose. Next, the adapter is coupled to the distal end of the dispensing hose using the threaded aperture of the adapter. Finally the dispensing nozzle is screwed back on to the distal end of the dispensing hose that is extending out of the adapter.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

(6) An adapter to be attached to the nozzle of a grease gun so as to provide a light source is provided, as well as a method for attaching the adapter to a grease gun.

(7) FIG. 1 shows a typical battery powered grease gun 10. The exemplary grease gun 10 preferably has a housing 12, a handle 14 extending from the housing 12, a receiver unit 16 connected to the housing 12, and a dispensing hose 18 extending from the housing 12. A dispensing nozzle 20 is attached to a distal end of the dispensing hose 18 and a control switch 22 is attached to or adjacent to the dispensing nozzle 20 to control the output of the grease gun 10. Receiver unit 16 receives a grease cartridge 24 and provides grease to the pump (not shown) located within the housing 12 and connected to the motor 26. The pump provides pressurized grease to the dispensing hose 18 that is fluidly connected to the pump.

(8) FIGS. 2 and 3 show an adapter 30 contemplated by the present invention. Adapter 30 has a body 31, a front portion 34, a back portion 32, two flat side portions 36, and rounded top and bottom portions 38. Adapter 30 further comprises a threaded aperture 40, a non-threaded aperture 42 having a front opening 44 and a back opening 46, and a setscrew 48 located on one of the two sides 36 of adapter 30. The location of setscrew 48 is such that it is adjacent to the non-threaded aperture 42.

(9) Threaded aperture 40 is sized so as to mate with a dispensing nozzle of a grease gun, such as dispensing nozzle 20 of the grease gun 10 shown in FIG. 1. The mating of the adapter 30 to the dispensing hose 18 using the threaded aperture 40 will be explained in more detail below.

(10) The back opening 46 of the non-threaded aperture 42 is located on the back 32 of adapter 30, and the front opening 44 of the non-threaded aperture 42 is located on the front 34 of adapter 30. In one embodiment, back opening 46 has a larger diameter than the diameter of the front opening 44.

(11) As shown in FIG. 4, the proportional relationship of the back opening 46 and the front opening 44 is such that a light source 50 can be held within the non-threaded aperture 42. The light source 50 will be held within the non-threaded aperture 42 by the back end 52 of the light source 50 being secured within the back opening 46 by means of setscrew 48, so that the front end 54 of the light source 50 that contains the light or bulb 56 will lie within the front opening 44. Once the light source 50 is placed within the non-threaded aperture 42, setscrew 48 can be tightened to engage and keep the light source 50 in place. In one or more embodiments, light source 50 is a LED flashlight wherein the back end 52 of the light source contains an ON/OFF mechanism 56.

(12) Once a light source 50 is secured within adapter 30, the adapter 30 is ready to be coupled to a dispensing hose 18 of grease gun 10 as shown in FIG. 5, although in some embodiments, the light source 50 can be secured within adapter 30 after adapter 30 has been coupled to a grease gun 10. To secure the adapter 30 to a grease gun, the dispensing nozzle 20 must first be removed from the dispensing hose. On a typical grease gun, such as grease gun 10, the dispensing nozzle 20 is attached to the dispensing hose 20 using a simple thread relationship wherein the dispensing hose 18 typically contains external threads, and the dispensing nozzle 20 contains internal threads. Once the dispensing nozzle 20 is removed, the adapter 30 is coupled to the dispensing hose 18 using the threaded aperture 40, which will typically contain internal threads which will be able to mate with the external threads of the dispensing hose 18. The dispensing hose 18 will now extend out of the threaded aperture 40, with the adapter 30 now coupled to the dispensing hose 18. Once the adapter 30 is coupled to the dispensing hose 18, the dispensing nozzle 20 can then be threaded onto the remaining external threads of the dispensing hose 18 extending out of the threaded aperture 40. Although dispensing hose 18 is shown as being a flexible hose, it is also contemplated that adapter 30 of the present invention can be used with a grease gun employing a rigid dispensing hose.

(13) Once installation of adapter 30 is complete, a user of the grease gun 10 will now be able to turn on the light source 50 using the ON/OFF mechanism 56 and be able to properly see the grease fitting that grease needs to be applied to. Furthermore, if the light source 50 either dies or burns out, the design of the adapter allows for simple replacement of the used light source 50 with a new light source 50, without removal of the adapter 30 from the grease gun 10. The user simply loosens setscrew 48, removes the used light source 50 from the non-threaded aperture 42, and installs a new light source 50 as described above.

(14) In light of the foregoing, it should be appreciated that the present invention significantly advances the art by providing an illumination means for a grease gun that is structurally and functionally improved in a number of ways. While particular embodiments of the invention have been disclosed in detail herein, it should be appreciated that the invention is not limited thereto or thereby inasmuch as variations on the invention herein will be readily appreciated by those of ordinary skill in the art. The scope of the invention shall be appreciated from the claims that follow.
