FIG. 1 is a side elevation plan view showing the inside view of the portable mechanical fan device of the present invention; and -
FIG. 2 is a top elevation plan view showing the inside top view of the portable mechanical fan device of the present invention. - Reference will now be made in detail to the present embodiment (exemplary embodiments) of the invention, Examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
- With reference to
FIG. 1 andFIG. 2 , an improved portable mechanical fan device is designed to be hand held and hand operated. The portable mechanical fan device comprises a spring loadedhand grip 10, one or morehand grip springs 11, a saw-tooth drive plate 8, upper andlower drive gears fan blade gear 5, afan blade shaft 4 and fourfan blades 3. The saw-tooth drive plate 8 is attached to the top of the spring loadedhand grip 10. Squeezing the spring loadedhand grip 10 by a hand drives the saw-tooth drive plate 8 against thelower drive gear 6 b which in turn drives theupper drive gear 6 a forward until theupper drive gear 6 a is meshed against thefan blade gear 5, as illustrated inFIG. 2 . Thefan blade gear 5 is attached to thefan blade shaft 4. The saw-tooth drive plate 8 being driven forward about one inch causes all associated gears to mesh and rotate, which in turn causes the fourfan blades 3 to rotate, thus causing air movement for a continuous cooling breeze. Releasing the spring loadedhand grip 10 allows the associated gears to be un-meshed which in turn allows the fourfan blades 3 to continue to rotate freely. Rapidly squeezing and releasing the spring loadedhand grip 10 allows for the continuous rotating of thefan blades 3, thus causing a continuous cooling breeze. - Referring to
FIG. 1 again, the portable mechanical fan device further comprises adrive gear casing 16 for containing the system of drive gears including the upper andlower drive gears fan blade gear 5 and thefan blade shaft 4. A cut-out slot 7 is provided at the inside of thedrive gear casing 16 and allows for the back and forth sliding movement of thedrive gear shaft 17 that theupper drive gear 6 a and thelower drive gear 6 b are mounted to, and mountingscrews 9 are used for attaching the sawtooth drive plate 8 to the top of the spring loadedhand grip 10. The spring loadedhand grip 10 is held in the outward position (towards left onFIG. 1 ) by thehand grip springs 11 when uncompressed. In the non-operational state the uncompressed spring loadedhand grip 10 is positioned outward (towards left onFIG. 1 ) which in turn positions the attached saw-tooth drive plate 8 outward (towards left onFIG. 1 ). The saw-tooth drive plate 8 is meshed against thelower drive gear 6 b pulling thelower drive gear 6 b outward (towards left onFIG. 1 ) and thus causing theupper drive gear 6 a to be unmeshed from the fanblade drive gear 5. In the operational state, thehand grip springs 11 are compressed by a hand squeezing the spring loadedhand grip 10 which in turn drives the saw-tooth drive plate 8 forward (towards right onFIG. 1 ) and meshes it against thelower drive gear 6 b. Thelower drive gear 6 b then moves theupper drive gear 6 a forward (towards right onFIG. 1 &FIG. 2 ) within the cut-out slot 7 causing theupper drive gear 6 a to mesh together with the fanblade drive gear 5 which in turn causes thefan blade shaft 4 to spin and then causes thefan blades 3 to rotate creating a cooling breeze. The travel of the spring loadedhand grip 10 and the attached saw-tooth drive plate 8 is approximately one inch that is determined by the dimension of the cut-out slot 7. Upon releasing the spring loadedhand grip 10, the hand grip springs 11 decompress causing the spring loadedhand grip 10 to be pushed outward (towards left onFIG. 1 ) which in turn drives the saw-tooth drive plate 8 outward (towards left onFIG. 1 ) pulling thelower drive gear 6 b back with it. At the same time, thelower drive gear 6 b pulls theupper drive gear 6 a which in turn allows for theupper drive gear 6 a to be unmeshed from the fanblade drive gear 5 in turn causing thelower drive gear 6 b andupper drive gear 6 a to slide backward (towards left onFIG. 1 ) within the cut-out slot 7. The fanblade drive shaft 4 and thefan blades 3 spin freely at this time because of the unmeshedupper drive gear 6 a from the fanblade drive gear 5. Continuous hand squeezing of the spring loadedhand grip 10 will provide for a continuous cooling breeze. The lowerfan body casing 12 is fastened together bybody casing screws 13 and the upperfan body casing 14 is fastened together bybody casing screws 15. - In addition, a
scent canister 1 is mounted at the top of the center of the fourfan blades 3. The scent canister 1 twists off to allow access for either applying scent drops to amini sponge 2 located in thescent canister 1 or for inserting a mini scent stick in thescent canister 1. Thescent canister 1 is then twisted back on and the fan is ready for operation that disseminates a refreshing aroma along with a cooling breeze. - Further, in the present invention, the spring loaded
hand grip 10 is designed to have an enlarged size so that it can physically accommodate the placement of all four fingers of either hand around for squeezing the hand grip for operation of the fan. So in the operational state, thehand grip springs 11 become compressed when the spring loadedhand grip 10 is squeezed by the push of all four fingers on the spring loadedhand grip 10. As a result, the saw-tooth drive plate 8 meshes with the system of drive gears includinglower drive gear 6 b,upper drive gear 6 a and fanblade drive gear 5, which together causes thefan blade shaft 4 to spin causing thefan blades 3 to rotate and thus creating a cooling breeze. The travel of the spring loadedhand grip 10 with the attached saw-tooth drive plate 8 is approximately one inch. The releasing of pressure by all four fingers on the spring loadedhand grip 10 allows for it to recoil to its natural starting position by way of the hand grip springs 11. The purpose of the hand grip springs 11 is for the recoil action of the spring loadedhand grip 10. This recoil action happens each time that pressure is released by way of all four fingers on the spring loadedhand grip 10. Each recoil of the spring loadedhand grip 10 with the attached saw-tooth drive plate 8 un-meshes thelower drive gear 6 b, theupper drive gear 6 a and the fanblade drive gear 5 from each other which in turn allows thefan blades 3 to spin freely. The continuous squeezing of the spring loadedhand grip 10 by all four fingers will provide for a continuous cooling breeze. - Although a particular embodiment of the invention has been described in detail for purposes of illustration, other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
