Description
TECHNICAL FIELD
[0001] The present disclosure relates to target practice with a
rifle, shotgun or handgun, e.g., pistol or revolver, and more
particularly, to target practice using an ultra-violet (UV) laser
apparatus in combination with the rifle, shotgun or handgun, and a
phosphor and/or photochromic paint coated target.
BACKGROUND
[0002] Proficiency with a weapon, e.g., rifle, shotgun, pistol or
revolver, requires practice. Learning how to properly aim and
accurately shoot the weapon at a target is a major component of
obtaining proficiency with the weapon. Budgetary and time
constraints, however, limit how often one can go to a shooting
range and shoot live ammunition. To compensate for a lack of live
ammunition training at the shooting range, electronic target
training that simulates the impact of a bullet on a target with
laser light is often used. Laser light target practice training
saves time, money and live ammunition, while providing for
maintaining shooting accuracy and proficiency, e.g., unsighted
fire, accuracy, grouping and trigger control. Laser light target
shooting provides for more frequent target practice, thereby
enabling a more confident shooter who can enjoy the benefit of
low-cost target training at any location without restriction or
concern for gun fire noise bothering neighbors or worrying about
the safety of where a fired live round may penetrate.
[0003] Existing laser light target practice devices use a visible
red or green wavelength laser that is activated by a firing pin of
the weapon striking a pressure or displacement switch, or a sound
activated switch that turns on the laser from the sound of a hammer
striking the firing pin. Either way, based upon the aim of the
individual, a brief pulse of laser light paints a target with a
visible spot of light where a live round would have hit the target.
One company has even introduced a laser trainer target that records
(saves locations) electronically when a laser light beam hits the
target each time the trigger is pulled by detecting the laser light
point with a plurality of photo detectors arranged in a matrix on
the target. Then after the laser target practice session is
finished, the electronic target can display all of the laser light
hits on a light emitting diode (LED) matrix on the target.
[0004] The laser generates a pulse of light each time the trigger
is pulled, but when using a paper target the visible laser light
pulse on the paper target is of very short duration and is easily
missed in combat or police training simulations. The electronic
target is better at displaying all laser light hits, but does not
show these hits in real time, rather the shooter must wait until
the target practice round is over before activating the electronic
target LED display that then shows the laser light hits stored in a
memory of the electronic target.
[0005] Referring to FIG. 1, depicted are drawings of various prior
art fire training lasers. FIG. 1(a) depicts a fire training laser
that fits into a front portion of a barrel of a gun and is
activated by either sound or acceleration of the hammer dropping
when the gun is fired. FIG. 1(b) depicts a fire training laser that
fits into the chamber (rear portion of the barrel) of a gun and is
activated by the firing pin hitting the back of the laser
mechanism. FIG. 1(c) depicts a fire training laser that fits into a
front portion of a barrel of a gun and is configurable for a
plurality different calibers with adaptor bushings (not shown). It
is activated by the sound or acceleration of the hammer dropping
when the gun is fired.
[0006] Referring to FIG. 2, depicted is a drawing of a prior art
training laser being used with a standard paper target. The laser
hit may be seen for only the pulse on time of the laser, e.g.,
about a 100 milliseconds. A gun 202 is aimed at a standard paper
target 208. When a trigger 204 thereof is pulled a hammer (not
shown) drops on a firing pin (not shown), thereby activating the
training laser device (inside of the barrel of the gun) that
produces a visible red or green laser light pulse 206 which briefly
appears at a spot 210 on a face of the target 208. The standard
paper target 208 does not allow the shooter to see groups of
multiple shots. It also does not allow the shooter to easily see
jerking and common problems with firing the gun. Since the laser
pulse 206 is only present for a fraction of a second, it is
difficult to see when the spot 210 appears on the face of the
target 208.
[0007] Referring to FIG. 3, depicted is a drawing of a prior art
training laser being used with an electronic recording target. Each
laser hit is detected and then recorded in an electronic memory
that may be accessed after the practice round has finished. A gun
202 is aimed at the electronic recording target 312. When a trigger
204 thereof is pulled a hammer (not shown) drops on a firing pin
(not shown), thereby activating the training laser device (inside
of the barrel of the gun) that produces a visible red or green
laser light pulse 206 which briefly appears at a spot 310 on a face
of the target 312. A photo (light) detector(s) at the location of
the spot 310 detects and then records in a memory (not shown) the
laser light hits (spots 310) for subsequent display after the
practice shooting round. The laser light detection portion 314 of
the target 312 also has a plurality of LEDs which are used to
display the laser light hits based upon the spots 310 stored in the
memory (not shown). The electronic recording target 312 is
expensive. The target 312 shows only one hit location per shot so
it will not show jerking, e.g., improper trigger pull. Present
electronic recording targets 312 do not show a hit location
immediately. The shooter must activate the hit record stored in the
memory after all shots have been taken to obtain a visual display
of the results of the shooting session. This delays feedback to the
shooter and takes longer for corrective action to be taken. The
target 312 generally runs on batteries that must be replaced
periodically.
SUMMARY
[0008] Therefore, it is desired to provide laser training target
practice at low cost, instant feedback after each shot by having a
longer persistence indication of where each shot landed on the face
of the target, indication of jerking when pulling the trigger, and
inexpensive and reusable targets that don't require a power source,
e.g., batteries.

[0029] While the present disclosure is susceptible to various
modifications and alternative forms, specific example embodiments
thereof have been shown in the drawings and are herein described in
detail. It should be understood, however, that the description
herein of specific example embodiments is not intended to limit the
disclosure to the particular forms disclosed herein, but on the
contrary, this disclosure is to cover all modifications and
equivalents as defined by the appended claims.
DETAILED DESCRIPTION
[0030] Referring now to the drawings, the details of specific
example embodiments are schematically illustrated. Like elements in
the drawings will be represented by like numbers, and similar
elements will be represented by like numbers with a different lower
case letter suffix.
[0031] Referring to FIG. 4, depicted is a drawing of an ultra
violet (UV) light training laser being used with a phosphor and/or
photochromic paint coated target, according to a specific example
embodiment of this disclosure. Unlike the prior art training laser
of FIG. 2, the laser hit may be seen for the duration of the
persistence of a phosphor coating on the target or permanently (or
semi-permanently) if photochromic paint is used with or in place of
the phosphor coating. A gun 202 is aimed at the phosphor and/or
photochromic paint coated target 408. When a trigger 204 thereof is
pulled a hammer (not shown) drops on a firing pin (not shown),
thereby activating the training laser device (inside of the barrel
of the gun) that produces a UV laser light pulse 406 which excites
the phosphor coating at a spot 410 on a face of the target 408.
Once the spot 410 of the phosphor coating has been excited by the
UV laser it will phosphoresce and remain so for the persistence of
the phosphor, e.g., from a few seconds to a minute or so.
[0032] There are various phosphor types having different
persistence and/or colors that are easy to see and remain visible
for a sufficient time to observe the accuracy of the shot(s) and
allow instant shot placement feedback to the shooter. If
photochromic paint is used in place of or in addition to the
phosphor coating, a permanent or semi-permanent record of the laser
shot placement may be achieved. Pulse width of the UV laser may be
adjusted for a desired phosphoresce (excitation) of the spot 410.
An advantage of the present invention is that a minimum pulse width
of the UV laser may be used, only long enough to excite the
phosphor, which will conserve battery life of the fire training
laser. It is contemplated and within the scope of this disclosure
that any of the fire training lasers shown in FIG. 1 may be used
with a UV light laser in place of the prior art red or green light
laser. Other and further shapes and configurations of fire training
lasers using a UV light laser would be readily apparent to one
having ordinary skill in the art of firearm training and having the
benefit of this disclosure.
[0033] Photochromic paints and coatings contain dyes that change
conformation when the film is exposed to UV light, and so they
change color. Depending on the composition of the color changing
paint, these pigments are either irreversible or they will
eventually return to their original color. Dye and chemical
formulas used in photochromic paints begin in a clear state, and
adopt other pigments because of molecular changes that occur when
the compound is exposed to heat or ultraviolet (UV)
light/radiation. Manufacturers can make these paints reversible or
irreversible.
[0034] Referring to FIG. 5, depicted are multiple UV laser hits on
the target of FIG. 4. Multiple shot hits 510 are shown and remain
visible for enough time to give the shooter real time shot
placement feedback. If the pulse width of the UV laser is set long
enough, jerking of the gun, e.g., trigger pull, will show as an
illuminated line 512. The angle and length of the line 512 will
give the shooter instant feedback as to what he or she is doing
wrong when shooting the gun.
[0035] If the phosphor coated target 408 (or photochromic paint
coated target) is used in direct sunlight, the UV light component
from the sunlight may cause the phosphor coating to slightly
phosphoresce. Normally the UV laser light illumination of a spot on
the target is of a much greater intensity then any background UV
light. However, if background UV light is a problem a simple shade
or "awning" may be used above and to the sides of the target such
that an "ambient light shadow" is cast over the target. Since the
face of the target is what is being aimed at, the shade or awning
over and around the target face will not interfere with the target
practice, and may also help the shooter for easily see the glowing
phosphor spots (representing shot hits) on the face of the target
in bright ambient light conditions, e.g., sunlight or over lighted
indoor shooting range.
[0036] Referring to FIG. 6, depicted is an exploded isometric view
of the construction of the target of FIG. 4, according to a
specific example embodiment of this disclosure. Standard paper or
reflective paper 624 is used to reflect any UV laser light that
gets through the phosphorus coating 622 and reflect it back to
increase energy transfer to the phosphorus. The reflective surface
of the paper 624 may range in reflectivity from a mirror-like
surface to high gloss photo paper. Non-reflective paper may be used
as well with reduced effectiveness. A phosphorus coating 622
applied to paper or a reflective surface 624. The phosphorus
coating 622 may be any color of available phosphorus. This coating
622 can be applied as a paint using spray or brush techniques, or
screen printed. Other methods of application may also be used. A
target pattern 620 is printed directly on a phosphorus coating 622.
The target pattern 620 may be printed thereon with a standard laser
or ink jet printer, silk screen process, or any other method of
printing images on a surface.
[0037] Referring to FIG. 7, depicted is an exploded isometric view
of the construction of a multiple color phosphor and/or
photochromic paint coated target, according to another specific
example embodiment of this disclosure. FIG. 7 shows another
embodiment of an improved phosphor coated target where multiple
colors of phosphorus are used at the same time. Multiple colors of
the phosphorus coating 722, e.g., 722a, 722b and 722c, may be used,
for example but not limited to, concentric rings around the center
of the target that enhances comparison of shot placement referenced
to the target center, e.g., bulls eye. Different dye color
photochromic paint may also be used to coat the paper 624 in a
similar pattern for a more permanent record of the training
session.
[0038] Other embodiments may comprise using phosphor coatings in
single or multiple colors on silhouettes, figures, and 3D targets.
UV based lasers include wavelengths from about 100 nanometers (nm)
to about 400 nm. Near UV or "blue light" lasers include wavelengths
from about 360 nm to about 480 nm. Use of both UV and near UV light
lasers are contemplated herein and any term herein referring to
"UV" also includes "near UV." A near UV 405 nm laser works well and
is readily available at a reasonable cost. The lower the UV
wavelength to excite the phosphorus, the brighter the phosphorus
will glow. Also, using a UV lower wavelength will make the UV laser
beam harder to see and only the shot location will be visible,
e.g., glowing phosphorus.
[0039] While embodiments of this disclosure have been depicted,
described, and are defined by reference to example embodiments of
the disclosure, such references do not imply a limitation on the
disclosure, and no such limitation is to be inferred. The subject
matter disclosed is capable of considerable modification,
alteration, and equivalents in form and function, as will occur to
those ordinarily skilled in the pertinent art and having the
benefit of this disclosure. The depicted and described embodiments
of this disclosure are examples only, and are not exhaustive of the
scope of the disclosure.
