The disclosure relates to pump devices and more particularly pertains to a new pump device for mechanically pumping fluids.
The prior art relates to pump devices. Existing pump devices come in many forms and many are hand powered. However, these devices lack internal gearing and momentum gathering weight discs to continue pumping while the hand is not in action.
An embodiment of the disclosure meets the needs presented above by generally comprising a pump housing having a housing front side, a housing back side, a housing left side, a housing right side, a housing top side, and a housing bottom side defining a housing inside. The housing front side has a fill aperture extending through to the housing inside. The housing back side has a supply aperture extending through to the housing inside. A fluid line is coupled within the pump housing. The fluid line is in fluid communication with the supply aperture and the fill aperture. A pump is coupled within the pump and is in fluid communication with the fluid line to bring fluid from the supply aperture to the fill aperture. A gear system is coupled within the pump housing. The gear system includes a weighted disc to maintain momentum once spinning. The gear system is in operational communication with the pump. A handle assembly is coupled to the pump housing and is in operational communication with the gear system to operate the pump.
There has thus been outlined, rather broadly, the more important features of the disclosure 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 disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A fluid line 36 is coupled within the pump housing 12. The fluid line 34 is in fluid communication with the supply aperture 30, the fill aperture 28, and the return aperture 32. A two-way valve 38 may be coupled to the fluid line 36. The two-way valve 38 is in operational communication with the fluid line 34 to direct fluid either to the fill aperture 28 or to the return aperture 32. A primer 40 may be coupled to the fluid line 34. The primer 40 may include a primer button 42 having a button shaft 44 extending through the housing top side 22 and a circular button head 46. The primer 40 is in operational communication with the fluid line 34 adjacent the return aperture 32 to draw fluid towards the return aperture 32.
A pump 48 is coupled within the pump housing 12 and is in fluid communication with the fluid line 36 to bring fluid from the supply aperture 30 to the fill aperture 28 or the return aperture 32 depending on the orientation of the two-way valve 38. A gear system 50 is coupled within the pump housing 12. The gear system 50 comprises a main shaft 52, a main gear 54 coupled to the main shaft, and a pump gear 56 coupled to the pump 48. The gear system 50 also includes a weighted disc 58 to maintain momentum once spinning. The weighted disc 58 may comprise a left weight half 60 and a right weight half 62 each coupled to the main shaft 52. A ratchet drive wheel 64 is coupled to the main shaft 52 and a drive pulley 66 is coupled to the ratchet drive wheel 64. The gear system 50 is in operational communication with the pump 48 so that as the drive pulley 66 is moved the pump 48 is engaged.
A handle assembly 68 comprises a handle frame 70 coupled to the housing top side 22. The handle frame 70 has a frame bottom side 72, a frame top side 74, a frame left side 76, a frame right side 78, a frame front side 80, and a frame back side 82 defining a frame inside 84. The frame left side 76 has a finger aperture 86 extending through the frame right side 78 configured to receive all of a user's fingers. The frame top side 74 has a lever aperture 88 extending through the frame inside 84. The handle frame 70 may have a guard portion 90 surrounding the finger aperture 86 and an extension portion 92 extending above the guard portion 90. The lever aperture 88 extends through the extension portion 92.
The handle assembly 68 further comprises a pump lever 94 coupled through the lever aperture 88 and is in operational communication with the drive pulley 66. The pump lever 94 may thus be depressed with the user's palm as the user's fingers are secured within the finger aperture 86. The pump lever 94 may be spring loaded to automatically return to a raised position after being depressed so it can be repeatedly squeezed to drive the pump 48.
A release trigger 96 may be coupled to the handle assembly 68. The release trigger 96 is coupled within a sidewall 98 of the finger aperture to be squeezed with the user's index finger. The release trigger 96 is in operational communication with the two-way valve 38. When the release trigger 96 is pulled it will route fluid to the fill aperture 28.
In use, the pump lever 94 is depressed to get the gear system 50 spinning. The primer button 42 is then depressed to draw fluid in through the supply aperture 30 to the pump 48. Once the fluid starts to flow through the return aperture 32, the release trigger 96 may be depressed to direct the flow to the fill aperture 28. The pump lever 94 is depressed again as the weighted disc 58 loses momentum.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
