DETAILED DISCUSSION OF THE INVENTION
Referring to FIG. 1, the preferred embodiment of the present invention is incorporated into a writing instrument 1, such as an ink pen, as shown, including a hollow body 2 having a inner 3' and outer 3 sidewalls, a first 4 end which may have a writing tip emanating therefrom, and a second end 7.
Continuing with FIGS. 5 and 6, the body 2 has formed through the sidewall 3 a longitudinal slot 8, the slot having second 8 and first 9 ends and a length 31 aligned with the longitudinal axis 6 of body 2, the first end 9 of slot formed near, but spaced from, the first end 4 of the writing instrument.
Formed in the body 2 in general perpendicular relationship with the longitudinal slot 8, between the first 9 end of the slot and the first end 4 of the writing instrument is a lateral slot 11 having a width 13 and spaced 12 from longitudinal slot 8.
Continuing with FIGS. 2-6, a generally flat 16 lens 15, which may be, for example, a fresnel type, is provided having a thickness 17 adequate to pass through lateral slot 11, the lens having first 19 and second 18 ends, a top side 29 and a bottom side 30 and a length 21, the length preferably corresponding with the length 31 of longitudinal slot 8. As shown, a radial curve 20 or bend 28 is formed in the lens in the vicinity of the first 19 end, directed upward from the top side 29 to form a viewing area 27, as well as to facilitate egress of the lens from the body of the pen, as will further be discussed infra.
Situated in spaced relationship 24 from the top side 29 of the lens in the vicinity of the second end 18 is a button 22 having a grip pad 23 supported above the lens 15 by support member 25 and fastened by fastener 26.
Continuing with FIGS. 1-6, the lens 15 is situated within the body 2 of the pen in longitudinal fashion, adjacent to the inner sidewall 3' such that the grip pad 23 of button 22 is exterior the body of the pen, with the support member 25 passing through longitudinal slot 8 and the first end 19 of lens 15 in communication with lateral slot 11 such that a user urging grip pad 23 outward 32 toward writing tip or first end 4 dispenses 33 the first end 19 of lens out of the body in a manner which allows the user, holding the writing utensil 1 in a writing position, to view through lens 15 to magnify an area adjacent to the first end 4 or writing tip (FIG. 6), placing the lens in a dispensed position.
As shown, the bend 28 or radial curve 20 not only facilitates dispensing with the upwardly directed portion at the first end threading through the lateral slot when being dispensed, but also directs the lens away from the body when in the dispensed position to facilitate viewing by the user through the lens while holding the writing instrument in the writing position.
After the lens has been utilized by the user in its open position, as shown in FIGS. 2 and 5, the user may retract same into the body of the writing instrument by urging the grip pad 23 away from the first end 4 and writing tip 5, facilitating the lens to slide back through lateral slot 11 and into the body 2.
FIG. 7 illustrates a first alternative embodiment of the present invention, wherein an adapter in the form of an enveloping shell 35 having a conduit therethrough is provided to engage the outer body of an off-the-shelf pen 36 by slipping the shell over same. As shown, the shell has a longitudinal compartment 37 to hold the lens 38, and a longitudinal slot 39 and lateral slot 40 with a construction and operation similar to that taught in the preferred embodiment, supra.
The user would merely slip the adapter over the body of a pen so that the lateral slot is adjacent to the writing tip. The adapter may be held in place via friction or adhesive, as is desired.
FIG. 9 illustrates a second alternative embodiment of the invention, wherein there is further provided a build in light emitter 41, in the form of, for example, a light emitting diode in the body 49 of the writing instrument, and in communication with lens 45. The light emitter is powered by a battery or other power supply 42 which may be engaged via push-button 43 switch 44 or by dispensing 47 the lens from the body via trip pad 46, so as to facilitate energizing of the light emitter 41, providing light from within the body of the writing instrument, which light is passes through lens like a fiber optic cable to illuminate 48 the exposed lens extending from the body, as well as an area in the vicinity of the first end 50 of body 49, which may include a writing or other surface, thereby providing both illumination and magnification, facilitating use in dark or low light areas.
FIG. 8 teaches a third alternative embodiment of the invention, wherein the second embodiment, above is provided in an adapter form configured to slip over an off-the-shelf pen. As shown, a shell in the form of the device of FIG. 7 is provided with the addition of a light emitter and power supply within the shell, as generally discussed in the discussion of FIG. 9, above. This embodiment of FIG. 8, however, may have to have an increased thickness compared to the shell of FIG. 7 to accommodate the power supply 51 and light emitter 52.
Actuation of the power supply may occur via switch 53 configured to engage upon the urging 54 the grip pad 56 towards the writing tip 59, dispensing 55 the lens, the switch the providing power via power supply to light emitter, which is situated within the shell adjacent to the lens, illuminating 57 same.
FIGS. 10-13 teach a fourth embodiment 60 of the present invention, wherein there is provided a pen having a body 61 having a cavity having an inner wall 61' wherein there is formed first 62 and second 62', facing grooves formed therein, the body having a longitudinal slot 63 formed between said first and second grooves configured to accommodate a flexible lens 64 having a first edge 65, and a second edge 69 having an activation button 66 affixed thereto, configured to be exposed outside of the body for manual operation by a user. The lens further has first 67 and second 68 lens configured to be slidingly engaged to the first 62 and second 62' ends, respectively, such that the first edge 65 is exposed outside of the body, allowing the user to read through it upon guiding the activation button 66 along slot 69' in a clockwise 72 direction, or enclose the lens to within the body by directing the activation button along slot 69' in a counter clockwise 71 direction. The embodiment shown, therefore, provides a lens having a body which is wrapped about the longitudinal axis of the body of the pen in a storage position, and is dispensed in a wide capacity from the body, which can provide a greater viewing area.
Alternately, an activation button 70 can be placed in medial relationship to the lens, as opposed to the edge connection shown in button 66.
An alternative embodiment 73 of the present invention teaches a body 74 having a longitudinal cavity 75 formed therethrough configured to envelope the body of an off-the-shelf pen, converting said pen into a magnification pen.
The invention embodiments herein described are done so in detail for exemplary purposes only, and may be subject to many different variations in design, structure, application and operation methodology. Thus, the detailed disclosures therein should be interpreted in an illustrative, exemplary manner, and not in a limited sense.
