## Title
Retractable magnifying glass accessory to a watch band

## Abstract

The present invention is a retractable magnifying glass having a magnifying glass with an aperture on one end, housing, spring positioned parallel to the magnifying glass within the housing and retractable cord. The housing has front and back sides and a first and second compartment. The back side has a strap connector for affixing to a strap. The first and second compartments are adjacent and parallel to each other and connected via a cord aperture. The second compartment has an open side to allow ingress and egress of the magnifying glass and a portion of the magnifying glass extends beyond this open side for easy access. The retractable cord is affixed within the first compartment with one end connected to the spring and the other extending through the cord aperture and connected to the aperture of the magnifying glass.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the field of portable optical magnification. More specifically the invention comprises the retractable magnifying glass device to be removably added to an existing watch band, bracelet, belt, purse strap, or any other strap.
2. Problem to be Solved and the Related Art
With age people become farsighted. They need glasses to see close objects. Bifocal glasses are one of the solutions to this problem, however some people do not like to wear glasses. When they are in the store they can see clearly the things they want to buy, however they cannot read the price, or other details. Present invention aims to solve this problem by enabling them to just pull out the magnifying glass from its mounting on the watch, belt, or purse strap, stretch it out to the object they want to read the text on, and let it retract back after they are done. It is a much easier and less time consuming process than having to put glasses on and take them off again and again, or search for a magnifying glass in a pocket or purse and remember to put it back.
There are retractable measuring tapes, and retractably mounted objects. For magnification there are several designs of portable magnifying glasses and optical glasses. The prior art U.S. Pat. No. 7,667,903B2, Retractably mounted magnifying glass assembly by Mary Kisko is meant to be connected to a flat surface with a stationary frame. The prior art U.S. Pat. No. 5,113,289, Shelf-mounted magnifying glass by Sara Soper, and U.S. Pat. No. 6,441,974 B1 Shopping cart magnifier (E-Z reader), by Thomas A. Miranda, Jonathan C. Roche, Randolph G. Duso have to be implemented by a store owner rather than a customer.
There are also existing patents on a magnifying glass incorporated as a part of a watch case or watch band: U.S. Pat. No. 2,679,785 A, Wrist watch by Hugo Batt, where a magnifying glass is a part of a watch case; U.S. Pat. No. 8,125,853 B2, Watch bracelet by Robert Greubel, Stephen Forsey has a magnifying glass as part of the bracelet; and U.S. Pat. No. 5,601,222, A Magnifying wristband by Richard Y. Haddad, has a magnifying glass permanently built into a watch band.
The present invention differs from previous patents. Rather than being connected to the surface of the stationary object it is designed with the size, positioning of its elements, and connector design to be easily added-on to a multi-surface, existing strap like watch band, belt, purse strap, or other strap and no changes to watch or watch band, or strap are required. It is portable, easy to make and its parts are not expensive.
BRIEF SUMMARY OF THE INVENTION
The object of the invention is to provide means of inexpensive, easily accessible, portable magnification. The present invention comprises a retractable magnifying glass device to be slid on a watch band, bracelet, belt, purse strap or any other strap. The device has a loop connected to the larger surface of its housing, made from rubber, plastic, velcro or similar material that can be slid on, or attached to the watch band. One can extend the magnifying glass from its mounting on the strap, and after use either place it back, or have it automatically retract into resting position inside the housing.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1: is one embodiment showing the device affixed to a band;
FIG. 2: is a cross-sectional view of one embodiment of the present invention;
FIG. 3: is a perspective view of the embodiment shown in FIG. 2; and
FIG. 4: is a perspective view of another embodiment of the present invention wherein the retractable magnifying glass and the housing each have a magnet on their side allowing the magnifying glass to be magnetically connected to the housing.

    1 strap (not part of the invention)
    2 housing
    3 magnifying glass
    4 retractable spring
    5 cord
    6 bead

    8 metal extension
    9 retractable spring housing
    10 strap connector
    21 housing compartment for a spring
    22 hosing compartment for a lens


DETAILED DESCRIPTION OF THE INVENTION
The magnifying glass has two positions: pulled out position and resting position. The magnifying glass comprises two parallel to each other large surfaces and two sets of parallel to each other narrow sides. The exterior of housing comprises two parallel to each other large surfaces and two sets of parallel to each other narrow sides.
FIG. 1 show the strap 1 with retractable magnifying glass 3 and the spring in a housing 2. The spring and separate compartment for the spring are not depicted. One of the large surfaces of the housing 2 is attached to the strap 1 with a strap connector 10. The other large surface of the housing has a notch to enable pulling out of the magnifying glass from the housing. The magnifying glass is inside the housing in its resting position.
FIG. 2 is a cross section showing the housing 2 with a divider inside the housing to hold the retractable spring 4 where the compartment 21 contains the spring 4 and compartment 22 contains a magnifying glass 3 in its resting position. The magnifying glass is connected by a cord going through a bead to a retractable spring. The bead attached to the far end of the housing redirects the cord which passes through its hole, to allow the magnifying glass to be in its resting position inside the housing parallel to the large surface of the spring compartment and parallel to the strap connector.
FIG. 3 shows the magnifying glass 3 pulled out from the separate compartment (not depicted) of the housing 2. The magnifying glass is connected to spring 4 by a cord 5 through a bead 6 to the farther end of the spring 4 allowing for automatic retraction of the magnifying glass 3 into the housing. In its resting position the magnifying glass 3 will be adjacent to the large surface of the housing compartment containing the spring 4. In this embodiment the edge of the magnifying glass closest to the housing in a pulled out position will end up next to the farther edge of the housing in the resting position.
FIG. 4 shows a different embodiment of the invention in the resting position with the retractable spring 4 and a magnifying glass 3 mounted side by side with the narrow edge of the magnifying glass parallel to the narrow edge of the spring housing. The spring housing 9 is attached with the strap connector (not depicted) to the strap. The spring 4 is connected with a cord 5 to the magnifying glass 3. The magnifying glass 3 is connected with a magnet 7 to the spring housing metal extension 8.
