ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to magnification lenses and, more specifically, to a magnification device which can be mounted onto display windows such as cellular phones, calculators, paging devices, etc., whereby the contents of the display window will be magnified.
The magnifying device is comprised of a housing member having a plurality of lenses contained therein which are removable. This may occur as having the lenses elements peelably removable as in the case of stacked lenses or relocatable as in the case of slots within the housing whereby the distance between the lenses can be altered by moving one lens to a greater or lesser distance relative to the other.
The purpose of both the peelable stacked lenses and the relocatable lenses is to be able to vary the magnification of the contents of the display window.
To magnify objects it is necessary to place a lens some distance from the object to be magnified whereby light rays are bent so that the object appears larger, which has been the scope of the prior art devices which are able to magnify the display to a minor extent. The reason that the magnification is to a minor extent is due to the limitation imposed by a single lens and the distance the lens can be placed from the display window.
The present invention uses two or more lenses whereby the first lens is placed over the display window and one or more lenses are strategically positioned over one another until the desired magnification has been achieved. Placing a 2× lens over the window with another 2× lens placed within the top exterior planar surface of the magnification housing device will result in a 4× display. By adding another 2× lens in between the first two lenses will result in an 8× display. The magnification limits of the display is a direct variable of the number of lenses used.
2. Description of the Prior Art
There are other magnifying devices designed for display enlargement. Typical of these is U.S. Pat. No. 4,451,117 issued to Goode on May 29, 1984.
Another patent was issued to Pine et al. on Dec. 24, 1991 as U.S. Pat. No. 5,075,799. Yet another U.S. Pat. No. 5,608,203 was issued to Finklestein et al. on Mar. 4, 1997 and still yet another was issued on Jan. 6, 1998 to McKay as U.S. Pat. No. 5,706,255.

Disclosed is a magnifying element for use with a digital watch face to magnify the numerals and hence facilitate the reading of the time thereby. The magnifying element has a face side and an adhesive coated side which is covered by tear strip whose removal exposes the adhesive side. Appropriate manipulative pressure applied to the face side of the magnifying element results in the adhesive coated side being attached to the digital watch face.

A timekeeper and magnifying device includes a watch and a magnifying lens pivotally connected to the watch. The lens may be pivoted away from the face of the watch to magnify objects. The device may include a light adjacent the magnifying lens which enables the device to be used in dark areas. Additionally, the device may contain a fastener which restricts the magnifying lens from pivoting away from the face of the watch. In the preferred embodiment of the invention, the magnifying lens may be either pivoted about the hinge or detached from the watch. In alternate embodiments of the invention, a connector removably holds the magnifying lens over the face of the watch. Furthermore, in other embodiments, the device further includes a second magnifying lens and a second hinge which cooperate with the first magnifying lens and the first hinge to form a telescope-like combination. A method for using the time-keeping and magnifying device is also disclosed.
While these magnifying devices may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
SUMMARY OF THE PRESENT INVENTION
The present invention discloses a magnification device for being removably mounted onto the display window of a cell phone or the like. The device discloses a housing member having a plurality of removable magnifying lenses contained therein. The lenses may be removable by being stacked onto each other or mounted in slots disposed in the housing. A strap is provided having mating hook and loop material on its ends for attachment about a cell phone or the like. An additional external hook and loop member is provided to allow attachment of the strap and cell phone to a proximate object. A removable clip may also be provided for attachment of the strap and cell phone to an article of clothing.
A primary object of the present invention is to provide a magnification device which can be mounted to display windows of electronic equipment such as cell phones, pages, calculators, watches, etc. for the purpose of optically enlarging the information displayed.
Another object of the present invention is to provide a magnification device having a housing member having means for fixedly attaching said magnification device to a display window.
Yet another object of the present invention is to provide a magnification device having a housing member having one or more magnification lenses positioned therein.
Still yet another object of the present invention is to provide a magnification device having a housing member having a plurality of stacked peelably removable lens wherein the light rays change direction at each air/lens interface until being emitted at the desired magnification.
Another object of the present invention is to provide a magnification device having a housing member having a plurality of slots whereby a plurality of lens elements can be selectively relocated until the light rays are emitted at the desired magnification.
Yet another object of the present invention is to provide a magnification device having a housing member comprised of separable housing elements each having a magnification lens contained therein, whereby a housing lens carrying element can be fixedly attached to the display window and the other housing lens carrying element can be fixedly attached to the electronic equipment exterior case, such as, a cell phone.
Still yet another object of the present invention is to provide a magnification device having a housing member, containing a plurality of lens elements, having a strap member for encompassing the electronic equipment.
Another object of the present invention is to provide a magnification device having a housing member, containing a plurality of lens elements, having a strap member for encompassing the electronic equipment.
Yet another object of the present invention is to provide a magnification device having a strap member for encompassing electronic equipment having one element of a mating fastening member exteriorly positioned whereby the second mating element can be fixedly attached to a structure, such as the dashboard of a motor vehicle, whereby the electronic equipment can be viewably selectively positioned.
Still yet another object of the present invention is to provide a magnification device which is cost effective to manufacture.
Additional objects of the present invention will appear as the description proceeds.
The present invention overcomes the sh
