Here is disclosed an elongate style portable mechanical fan device having
an elongate body handle portion including a four blade fan device mounted
on the top end of the body portion. The elongate handle portion is
designed with a spring loaded grip for mechanical squeeze operation. A
twist top scent canister is mounted on center at the top of the four
blade fan device. A further embodiment contemplates that scent drops may
be added to a mini sponge located in this scent canister or a scent stick
may be added in place of the mini sponge, so that the rotating fan blades
will disseminate the scent emanating from the scent canister.
1. A portable mechanical fan device designed to be hand held and operated
by squeezing a spring loaded handle, which in turn meshes a gear system
together, which in turn spins the fan blade shaft, which in turn causes
the fan blades to rotate providing a cooling breeze to the user.
2. A portable mechanical fan device with said fan blades to have scent canister attached to the center blade body point, with which scent drops may be added to a mini sponge or with which a scent stick may be installed in it's place, which in turn will allow for the rotating fan blades to disseminate the scent emanating from the scent canister towards the user when the mechanical fan device is in operation.
FIELD OF THE INVENTION
The present application claims the benefit of U.S. Provisional Application No. 60/907,083 filed Mar. 19, 2007, which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
The art field relative to the invention, development and engineering of the portable hand held fan is well established. From the 1800's into the early part of the 1900's came the development of the portable mechanical fan. The early 1900's then developed into the portable electric fans which are today commercially manufactured in numbers to large to count. Such designed portable fans, being either mechanically or electrically operated, are intended to be held by the user by a formed hand grip of some type with the fan blades facing the user. Such portable fans are intended to be mechanically or electrically operated for the cooling breeze that the device provides to the user.
It is accordingly a primary object of the invention to be utilized as a hand held fan by the user.
This is achieved by a spring loaded squeeze handle on the body portion is retracted and released causing a gear system to mesh together thus causing the four fan blades to rotate.
SUMMARY OF THE INVENTION
In accordance with the invention, In summary, the present invention provides an improved mechanical portable fan device which is intended to be utilized as a hand held unit by the user. In the preferred embodiment, a spring loaded squeeze handle on the body portion is retracted and released causing a gear system to mesh together thus causing the four fan blades to rotate. The device is further designed such that once the four fan blades are in motion they will continue to rotate freely between the squeezing action of the spring loaded handle allowing the user to enjoy the cooling effects of the fan device.
A further feature of the preferred embodiment of the invention is the addition of the scent canister mounted at the heart of the four fan blades. It has a twist top that can be removed to either add scent drops to the mini sponge or to replace the mini sponge with a scent stick. Upon the operation of the fan device the user will have the added benefit of a scented breeze. In this manner, the fan might not only be used as a cooling device, but also as an air freshening device as well.
This device was designed for it's simplicity of operation and the fact that it can be manufactured from recycled materials being metal and plastic, or all together plastic. There are no toxic batteries needed for it's operation and no toxic batteries to dispose of, such as used by the present day portable fan devices. This fan device is as Green as it gets. This fan device also comes with a scent canister. Aromatic scents may be added for purely refreshing breezes, or scents such as Vicks may be added for therapeutic purposes and may assist people with clearer breathing along with the added cooling breeze effect. A further embodiment is that the physical operation of this fan device may improve wrist, hand and finger strength which may in turn assist with better coordination and dexterity of the stated same.
This mechanical fan device was designed with the intent to be used at outdoor sporting events or concerts where temperatures might be high and the cooling breeze generated by this fan device might provide some cooling relief from the heat. This mechanical fan device could also be color coded with attached decals to match any athletic team's colors whether it be professional or amateur such as for football, baseball, soccer, tennis, golf, or any other outdoor summer sporting or amusement park event, etc. There will be no expensive batteries to run down with the need to be replaced over and over again.
Additional objects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate one (several) embodiment(s) of the invention and together with the description, serve to explain the principles of the invention.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a side elevational plan view showing the inside view of the portable mechanical fan device of the present invention.
FIG. 2 is a top elevational plan view showing the inside top view of the portable mechanical fan device of the present invention.
DESCRIPTION OF THE EMBODIMENTS
Reference will now be made in detail to the present embodiment (exemplary embodiments) of the invention, an example(s) of which is (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 and FIG. 2 on the drawing sheet the following applies: The saw-tooth drive plate 8 is attached to the top of the squeeze handle 10. Retracting the squeeze handle 10 into the handle base support 12 drives the saw-tooth drive plate 8 against the lower gear 6b which in turn drives the upper gear 6a forward until it is meshed against the fan blade gear 5. The fan blade gear 5 is attached to the fan blade shaft 4. The saw-tooth drive plate 8 is driven forward 1'' causing all associated gears to mesh and rotate which in turn causes the four fan blades 3 to rotate, thus causing air movement for a continuous cooling breeze. Releasing the squeeze handle 10 allows the associated gears to un-mesh which in turn allows the four fan blades 3 to continue to rotate freely. Rapidly retracting and releasing the squeeze handle 10 allows for the continuous rotating of the fan blades 3, thus causing a continuous cooling breeze. The scent canister (twist top) 1 twists off to allow access to the mini sponge 2. Scent drops may be applied to the mini sponge 2 or a mini scented stick may be installed in it's place. The scent canister (twist top) 1 is then twisted back on and the fan is then ready for operation that will provide a refreshing aroma along with a cooling breeze to the user.
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.
