This invention relates to locating keyholes, and in particular orienting keys for insertion in the keyholes.
Many of us get frustrated, at least occasionally, trying to unlock a door. Many people encounter problems unlocking a door. One problem is actually locating the keyhole or keyway. This problem is common in a darkened situation, and also where the surroundings are very bright, but the lock is in a shadow or the users shadow falls across the lock face.
Once the lock is located, a second problem can arise, namely how to orient the key to correctly enter the lock. There is no standard for orienting the keyhole, no way for someone to be sure of the orientation in many situations. Although cylinder locks, at least in North America, have standardized on cylinder plug size, they have not standardized on key blade orientation, which may be keyed saw teeth or cuts up, down, right, or left.
For the visually impaired, these problems can be frequent irritants. In certain situations, these problems can make these people as well as anyone else vulnerable, by slowing down their entry into the protection of their private spaces, such as houses and apartments.
In hostile climates, problems unlocking a door may also extend the time people are exposed to extreme weather. For the young and the elderly, this can lead to increased chances of contracting colds, frostbite, and other illnesses.
Recently, small lights have been manufactured for use on key chains. The purpose of these lights is often to illuminate an area to find the keyhole. However, because these lights are on the key chain, they must be gotten out of the way so that the key can actually be inserted in the keyhole. When the light is most needed, it cannot be readily used. What is needed is a way to take advantage of the light when it is needed most, for inserting the key into the keyhole.
For clarity, common terms used by locksmiths and within this document are defined in the table below.
The invention includes apparatus aiding in locating a keyhole on a lock cylinder and orienting a key to the keyhole. The lock cylinder is also known as the cylinder lock plug. The apparatus was referred to in the provisional patent application as a keyhole locator. The keyhole is also known as a keyway. The means for finding the location of the lock cylinder will guide a person attempting to enter a key into the keyhole of the lock cylinder. The means for determining the orientation of the keyhole will guide the person attempting to enter the key into the keyhole as to the proper orientation of the key.
As used herein, a lock will include a lock cylinder containing the keyhole, the lock cylinder also includes the key interface, which when engaged by an inserted key, is used to lock and/or unlock the lock. The lock may be part of a automotive vehicle door, a door knob, or a dead bolt. The automotive vehicle door will refer to a door on an automotive vehicle. An automotive vehicle refers to a self-powered moving vehicle, which by way of example may include, but is not limited to, an automobile, a truck, a tractor, a fork lift, a combine, an airplane, and/or a crane. As used herein a door on an automotive vehicle may include, but is not limited to, a door to passenger section, a driver's section, a cargo compartment, an engine compartment, and a fuel supply point and/or compartment.

An exposure 30 minutes to sunlight tends to product over tend hours of glow on embodiments with an UV protective layer 350.
The luminescent material 320 preferably contains at least one photo luminescent pigment. As used herein, photo luminescent pigments were first developed in 1976. These original pigments were fully annealed zinc sulfide crystals. More recently, pigments were introduced using strontium aluminate pigments. These pigments are much brighter than zinc and were the first UV resistant product on the market. They are the brightest and have the longest decline time on the market. The pigments store light energy (daylight or artificial light). They emit this energy as a bright, glowing, visible light in the darkness or through dense smoke and fog. They do not have any radioactive additives and are non-toxic.
Versions of the sheet 370 are currently manufactured by two companies. The first version is sold the brand name “Glo Bright™” and made by Jessup Manufacturing Company, Post Office Box 366, McHenry Ill. 60051 USA, which is preferred. The second version is the Permalite™ products, which are distributed in the United States by G. S. I. Inc., 3051 Pine Street, Clearwater, Fla., USA 33763-0914.
