Millions of people wear glasses (for reading, distance vision, sun-shading, etc.) and need to put-on and take-off those glasses many times a day. For example, reading glasses may be put-on and taken-off many dozens of times a day. Those people must find a place to put the glasses when not in use. Furthermore, that place should be always secure and conveniently accessible, for fast put-on (“quick draw”) and fast take-off (“quick stow”). Several improvised approaches meet one or two of these requirements, but fail miserably on at least one requirement. Thus there is an unmet need for a quick draw and quick stow eyeglass holder.
As of 2012, you can buy (e.g. on Ebay.com) at least ten differently decorated magnetic eyeglass holders. However, 100% of those holders magnetically hold a “loop”, through which the user must “thread the needle” with one temple piece. This thread the needle task can be frustratingly tedious and slow. This is especially likely when the user is not visually focusing on the loop (e.g. while making eye contact with another person during a conversation). Worse yet, the eyeglasses can be reading glasses which are required before it is possible for him to focus on the loop.

In order to more accurately and concisely describe the present invention, the following terms are first listed, then are defined below:
Note: Previously defined terms are italicized in the definitions below and other sections of this application.
article of clothing is generally defined as commonly defined in an ordinary dictionary.
bracket is defined as a way of fastening or joining a plurality of objects.
cloth-gripping-strength is defined as the magnitude of net force that keeps an object from sliding (generally down, generally due to gravity), along a cloth object.
damaged eyeglasses is generally defined as eyeglasses with significantly compromised optical or aesthetic properties, generally due to being dropped to the ground or floor.
eyeglass is defined as an apparatus with at least one lens for improving vision, or aesthetic style, which is mechanically supported by at least one ear and a nose.
eyeglass hinge is defined as a movable joint that allows the eyeglasses to fold into a more compact configuration. Eyeglass hinges are typically located near the outside of each lens, and generally attached to an eyeglass frame that generally holds the eyeglass lenses.
eyeglass hinge segment is defined as the section of eyeglasses (frame/temple piece) that is located approximately a quarter-inch from an eyeglass hinge.
eyeglasses weight is defined as total weight of eyeglasses, in grams.
Heat-shrink-tubing is defined as tubing that can shrink when heated, it can have adhesive on the interior surface too. The optional adhesive can be ordinary or heat activated.
Hinge-closing-spring-strength is defined as the spring-powered force that the eyeglass hinge can exert to keep the eyeglasses folded in the more compact configuration.
loop-based holders is defined as eyeglass holders that require eyeglass temple piece to be threaded into a loop-of-material, in order to hold the eyeglasses.
magnet-wrapper is defined as an object that substantially surrounds a magnet in order to mechanically hold the magnet. Often the wrapper is fastened to something else.
magnet1 is defined as a strong permanent magnet (typically a Neodymium magnet) that can be semi-permanently fastened to a pair of eyeglasses without adding excessive mass, volume, or otherwise ugly or distracting appearances. Here, semi-permanently fastened means, fastened for months, rather than for a few minutes or hours.
magnet2 is defined as a strong permanent magnet (typically a Neodymium magnet) that can be temporarily magnetically fastened to Magnet1.
magnet3 is defined as a strong permanent magnet (typically a Neodymium magnet) that can be temporarily magnetically fastened to Magnet2, with a section of cloth securely clamped between Magnet2 and Magnet3. Magnet2 and Magnet3 can be identical in shape, size and strength.
Quick draw is defined as the relatively rapid process of fetching a pair of eyeglasses from their stowed location in preparation to use the glasses.
Quick stow is defined as the relatively rapid process of putting away a pair of eyeglasses into their stowed location.
self-aligning is defined as a property of a plurality of magnets such that they tend to orient themselves in geometric alignment, due to attractive magnetic forces.
self-polarizing is defined as a property of a plurality of magnets such that they tend to orient themselves North-near-South alignment, due to magnetic forces.
Self-centering of magnets is defined as the effect of magnetic forces between two, or more, magnets that tends to “find” and attract each other.
Self-pole-flipping of magnets is defined as the effect of magnetic forces between two, or more, magnets such that they automatically find their strongest magnetic bond. That is, they will sometimes physically flip over one magnet such that the resulting nearest large magnet faces are of opposite polarity (providing the strongest magnetic bond). (Note that magnets can get stuck in local energy minima, which do not provide the strongest magnetic bond. To avoid this, the magnets need to be given the freedom and space to find their global energy minimum).
semi-permanent magnet fastener is defined as the way of semi permanently fastening magnet1 to a pair of eyeglasses. An example of a semi-permanent magnet fastener is a segment of shrunk heat-shrink-tubing, after placing it over magnet1 and over the temple piece end segment containing a widest segment point. Here, semi-permanently fastened means, fastened for months, rather than for a few minutes or hours.
shirt is generally defined as an article of clothing, or specifically corresponding to the common meaning of “shirt.”
slow-frustrating-stow is generally defined as an undesirable process of putting away eyeglasses for temporary storage.
slow-frustrating-draw is generally defined as an undesirable process of fetching eyeglasses from some stowed location.
Stowed location is defined as the location where a pair of eyeglasses are placed when not being used.
temple piece is defined as that portion of a pair of eyeglasses that extends from the eyeglass hinge, or where a hinge would normally be located, toward one ear (the associated ear). There are typically two temple pieces on each pair of eyeglasses, one for each associated ear.
temple piece end segment is defined as that section of the temple piece that extends about one inch from the temple piece tip. Very often this temple piece end segment is contains a widest segment point, which can be used to secure a semi-permanent magnet fastener, such as heat-shrink-tubing, to the temple piece.
temple piece tip is defined as the very end of the temple piece, nearest the associated ear.
temporarily magnetically fastened is defined as the joining of two objects by an attractive magnetic force which can be un joined by pulling apart those objects.
User is defined the person using or wearing the Eyeglasses that are, or are to be, magnetically held.
variable magnetic gap is defined as an adjustable final (equilibrium) separation of magnet#1 and magnet#2. For example, two wedges can be slid closer together to increase the gap.
widest segment point is defined as that location along a temple piece (generally a temple piece end segment) that is dimensionally wider than any other nearby location along the temple piece (generally a temple piece end segment).
It should be noted that this heat-shrink-tubing must withstand significantly strong forces that try to separate magnet#1 from the eyeglasses, especially when moving actively (e.g. running). Yet, the heat-shrink-tubing must be thin enough to allow minimal magnetic field reduction due to the resulting gap between magnet#1 and magnet#2. Aesthetically, the heat-shrink-tubing should be nearly invisible (e.g. hidden behind the user's ear), not colored (e.g. clear), or colored to please the user.
The temple piece end segment 47 is shown in magnified detail in
Note that magnet#1 is intended to be attached at the eyeglass-hinge-segment 46—or—temple piece end segment 47, but not both, for a give pair of eyeglasses.
Notice that a surface of magnet#1 typically protrudes through, or is substantially flush with, a surface of each magnet-wrapper. This allows for a strong magnetic attractive force (between magnet#1 and magnet#2), by keeping the magnetic gap small.
This type of magnet-wrapper can be especially easy for the user to attach himself/herself.
a is a perspective drawing of a pair of eyeglasses showing another magnet attachment approach. A cross section view plane is shown. This approach makes the heat-shrink tubing process unnecessary. It is for mass production. The cross section viewing plane 214 refers to what
b is a cross section drawing the temple piece showing a molded-in magnet. Here, the magnet is molded into the eyeglass temple piece or frame. High strength magnets can be somewhat expensive. This will add some base cost to the eyeglasses. Note that the magnet is exposed on the outside surface of the eyeglasses and that there is no heat-shrink tube wall thickness to separate magnet #1 from magnet#2. Therefore, this molded-in magnet #1 can be smaller (or magnetically weaker) that a magnet#1 separated from magnet#2 by heat-shrink tubing wall thickness (typically several thousands of an inch). In fact, an excessively strong attraction between magnet#1 and #2 can result in a undesired separation of magnets #2 and #3. The smaller magnet #1 can keep the temple piece physically strong, too.
Also, a slight variation on
c is a cross section drawing the temple piece showing a molded-in cavity, which can hold a low cost plastic plug or a magnet. Since high strength magnets can be somewhat expensive, the plastic plug option allows very high volume, low cost mass production, yet allows easy magnet attachment. Optionally, small detents can keep the magnet or plastic/metal plugs in place. (Note that most of the magnetic force will pull the magnet or plug even more securely into the cavity).
a is a side view and end view of a section of heat-shrink tubing 230 with removed sharp-irritating-edges by beveled edges 234. This is important and can require specialized tools to accomplish this beveled edge on such a thin (typically a few thousands of an inch) and less-than-rigid material, in a high volume, cost effective manner. (Note that some people might incorrectly think that beveling the edges might make the heat-shrink-tubing more irritating. However, the relatively high flexibility of the heat-shrink-tubing is such that beveling indeed makes it less irritating).
b is another side view and end view of a section of heat-shrink tubing 230 with removed sharp-irritating-edges by beveled edges 234. This is important and can require specialized tools to accomplish this beveled edge on such a thin (typically a few thousands of an inch) and less-than-rigid material, in a high volume, cost effective manner. Note that the tapers represented in

c is a perspective view of region 246 with magnet 261 and already-shrunk heat-shrink-tubing 264.
d is a perspective view of a pair of glasses 273 with heats-shrink (or otherwise bonded) magnet 272 which is hanging by stronger magnet 271 which is magnetically (or otherwise) bonded to an iron-containing object 270 (such as a screw or sheet metal).
After the foregoing disclosures, (i.e. with hindsight) some people might be tempted to say that this preferred embodiment of the present invention is obvious to the person of average skill average in the art. However, it is not obvious especially when one sees numerous different loop-based holders on the market that typically sell for about $15 each, despite their cost disadvantage from the requirement of at least one specially manufactured component (e.g. a loop and attachment). An embodiment of the present invention has an extreme sales advantage: Namely, no new manufacturing is needed! Three mass produced magnets can be purchased in volume, off the shelf, and a whole kit can be shipped in a very small blister pack for high profit margin and very low cost of entry.
Furthermore, an inexpensive kit like the present preferred embodiment of the present invention solves a crucial “chicken-and-the-egg problem”. That is, established eyeglass frame makers will not invest in thousands of new frame/temple-piece molds in order to mold-in magnets, until there is a large proven market. Only an inexpensive kit, for modifying ordinary mass produced eyeglasses, can develop a large proven market.
Moreover, one can use the present embodiment to clearly see and experience the significant improvements, as have friends of the author. Also non-obvious, is the precise balancing of magnetic bond strength (strong enough between magnets #2 and #3 to grasp clothing without slipping and weak enough to be removed when necessary, and weaker but adequate magnetic bond strength between magnet s #1 and #2, allowing easy quick draw, yet secure bond during jogging and running. In some embodiments, the thickness of heat-shrink tubing acts to increase the magnetic gap by just the right amount (e.g. when magnet#2 and magnet#3 are the same size and strength).
Also, cost effective, high strength-to-size ratio neodymium magnets have only recently become widely available, making the present embodiment the first practical embodiment of its kind.
Another unobvious aspect: Things that people visibly wear need to meet their aesthetic standards. An embodiment of the present invention includes one or more symbols, artworks or images which can artfully personalize magnet#2, which looks clean (no loop) and as artful as a lapel pin (like a US flag), and still provides the other benefits of quick-draw and quick-stow eyeglass holders.
Thus, this Preferred Embodiment of the Present Invention is Clearly not Obvious.
Thus, a Quick Draw and Quick Stow Magnetic Eyeglass Holder has been disclosed in extensive detail. It should be understood that innovations disclosed herein can be more generally applied than explicitly stated. To the extent that such variations do not depart from the spirit of the invention, they are intended to be included within the scope thereof which is assessed only by a fair interpretation of the following claims.
