Description
REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional Ser.
No. 60/692,813 filed on Jun. 22, 2005, the entire contents of which
are hereby incorporated by reference.
FIELD OF THE INVENTION
[0002] The present invention relates generally to shooting targets,
and more specifically, to movable shooting targets such as those
used in automated targeting systems found in shooting ranges.
BACKGROUND OF THE INVENTION
[0003] Various types of shooting targets have been developed and
sold, including both stationary and moving targets. Their designs
vary widely and are largely driven by the particular needs of the
shooter and the specific environment in which the targets are
used.
[0004] For instance, standard bulls-eye type targets having a
retrieval drive mechanism powered by an electric motor are commonly
found in shooting range firing lanes and are used by shooters who
want to practice shooting at a stationary target. Pop-up type
targets and moving targets, on the other hand, provide the shooter
with a more dynamic target environment, and sometimes move the
target with a drive mechanism that is powered by either pneumatic,
electric or hydraulic means.
[0005] Some examples of different types of shooting targets are
disclosed in U.S. Pat. No. 6,808,177 issued to Dehart; U.S. Pat.
No. 6,325,376 to Elliott et al.; U.S. Pat. No. 5,232,227 to Bateman
and U.S. Pat. No. 3,515,388 to Zachmeier.
SUMMARY OF THE INVENTION
[0006] According to one aspect of the invention, there is provided
a shooting target apparatus that comprises a frame, an obstruction,
a drive mechanism, a movable target holder, and a target, whereby
activation of the drive mechanism moves the target between
generally coplanar concealed and presented positions. When the
target is in the concealed position it is hidden from a shooter by
the obstruction, and when the target is in the presented position
it is revealed to the shooter.
[0007] According to another aspect of the invention, there is
provided a shooting target apparatus that comprises a frame, an
obstruction, a movable target holder generally located behind the
obstruction and including a pivot arm pivotally connected to the
frame, a pneumatic drive mechanism, and a target. Activation of the
pneumatic drive mechanism causes an air cylinder to tilt the
movable target holder about a pivotal connection so that the target
is moved between a concealed position and a presented position.
[0008] According to yet another aspect of the invention, there is
provided a shooting target apparatus that comprises a frame, an
obstruction, a movable target holder generally located behind the
obstruction and including a plurality of linkage members, a
pneumatic drive mechanism, and a target. Activation of the
pneumatic drive mechanism causes an air cylinder to pivotally move
a plurality of linkage members so that the target is moved between
a concealed position and a presented position.

DESCRIPTION OF PREFERRED EMBODIMENTS
[0017] The shooting target apparatus disclosed herein is a
pneumatically-driven device that provides a shooter with a dynamic
and engaging target shooting experience and can be used in a number
of different capacities, including indoor and outdoor training,
competition, and recreational settings. Depending upon the
particular manner in which it is used, the shooting target
apparatus can be set up by itself as a stand-alone target, with
other targets as part of a larger shooting course, in a traditional
shooting lane, or in any other target shooting application known to
those skilled in the art.
[0018] With reference to FIGS. 1-4, there is shown a first
embodiment of a shooting target apparatus 10 that tilts a target,
such as a hostage taker target, between several generally coplanar
positions, some of which reveal the target to the shooter and some
of which hide the target behind an obstruction. According to the
embodiment shown here, shooting target apparatus 10 includes a
frame 14, an obstruction 16, a movable target holder 18, a drive
mechanism 20, and a target 22.
[0019] Frame 14 acts as a foundation for supporting the other
components of shooting target apparatus 10, and generally includes
a base 28, a pair of mounting receptacles 30, 32, a pair of upright
posts 34, 36, and a bracket 42. Of course, other frame
constructions can also be used, including frames formed with
plates, ones having wheels or other components for improved
portability, or ones made from materials other than steel, to name
but a few possibilities. Base 28 preferably includes several,
transversely-connected steel members that lie on the ground to
provide a solid foundation for the apparatus. Mounting receptacles
30, 32 are welded or otherwise attached to base 28 and receive
posts 34, 36, respectively, so that the posts are maintained in a
vertically-upright and generally parallel orientation.
Quick-release pins 38, 40, which can be connected to mounting
receptacles 30, 32 with cables to prevent them from being lost, are
used to non-permanently secure the upright posts in their
corresponding receptacles. This makes for easy assembly and
disassembly of the shooting target apparatus. Because of their
similarity, a separate description of post 34 has been omitted.
Bracket 42 is securely fastened to frame 28 and extends upwards so
that drive mechanism 20 can be attached to it and has a component
to which it can anchor itself.
[0020] Obstruction 16 is generally located in front of target 22
and simulates an object, such as a hostage, that hides or otherwise
blocks the target from the shooter. The obstruction is preferably
sized to block the entire target when apparatus 10 is in a
concealed position, however, it could be designed to block only a
portion of the target and thereby leave a portion exposed for the
shooter to aim at. Preferably, obstruction 16 and target 22 conform
with the guidelines set forth by the International Practical
Shooting Confederation (IPSC), however, other types and size
targets could be used as well. As an example, obstruction 16 can be
the same type of target as the target 22, only turned around
backwards so that the indicia on the target does not face the
shooter. Although a stationary obstruction is shown here, it is
also possible to couple the obstruction to drive mechanism 20 or
some other mechanism so that the obstruction also moves during
operation.
[0021] Movable target holder 18 supports target 22 as it is tilted
between several generally coplanar positions, including the
concealed and presented positions mentioned above. According to one
embodiment, the movable target holder includes a pivot arm 50, a
cross member 52, a pivot bracket 54, a pair of mounting receptacles
56, 58, a pair of posts 60, 62, and an actuator main frame 64. As
its name suggests, pivot arm 50 is pivotally attached to base 28 so
that it can move through an angular range of motion that spans a
number of generally coplanar positions. Cross member 52 is
transversely attached to pivot arm 50 and supports mounting
receptacles 56, 58 at each of its ends. As previously explained in
greater detail, each of the mounting receptacles secures a post 60,
62 in a generally upright orientation and can utilize quick release
pins for easy assembly and disassembly. Pivot bracket 54, which is
best seen in FIG. 4, extends outwards and away from pivot arm 50
and provides a connection point for drive mechanism 20 so that
movement generated by the drive mechanism can be coupled to movable
target holder 18.
[0022] Actuator main frame 64 generally extends between bracket 42
of the frame and pivot bracket 54 of the movable target holder, and
is designed to maintain two or more pneumatic cylinders in a
generally coaxial alignment. The actuator main frame 64 can be
constructed from angle iron or any other appropriate material, and
includes anti-rotation features 70-76 that prevent the air
cylinders from rotating during operation. These features include
one or more slotted blocks 70 which extends from an end of actuator
main frame 64 and captures a flat section of the air cylinder rods
so that it is prevented from rotating. The slotted block 70 is
welded to a slide plate 72 that slides in and out of a space formed
with spacers and between a steel cover plate 74 and actuator main
frame 64. In this manner, the slotted block 70 can move with the
drive mechanism as it cycles through a range of motion. A switch
actuator plate 76 can be welded to the opposite end of slide plate
72 and can interact with mechanical and/or electrical switches that
provide data regarding the position of the air cylinders.
[0023] Drive mechanism 20 uses pressurized air to tilt movable
target holder 18 through a variety of generally coplanar positions,
and generally includes an air connection 80, a valve 82, and a pair
of actuators or air cylinders 84, 86. Pressurized air from a
compressor or some type of air rail is provided to connection 80
(all air connections preferably use push lock or other
quick-release fittings) and is regulated by an electrically
controlled valve 82. Air connection 80, as well as other components
of the pneumatic drive mechanism, can be protected from stray
bullets with a shield like component 88. Each of the air cylinders
84, 86 is preferably a bi-direction, single-rod pneumatic cylinder,
and when they are used in a serial or end-to-end arrangement, it
allows for several different positional combinations. According to
a first presented position (not shown), both air cylinders 84, 86
have their rods retracted within their cylinders, which results in
target 22 being tilted out to the right of obstruction 16. This
provides the most retracted or shortest overall length that the
pair of cylinders can assume, and is referred to as a
right-presented position. In a concealed position (shown in
phantom), one of the air cylinders 84, 86 is retracted and one is
extended; this results in target 22 being located directly behind
and therefore hidden by obstruction 16. According to a
left-presented position (shown in solid lines), both air cylinders
are extended so that target 22 is tilted out to the left of
obstruction 16. Air cylinder 86 preferably has a rod end attached
to bracket 42 with a clevis joint or some other rotatable
connection, and a cylinder end that is attached to air cylinder 84.
Similarly, air cylinder 84 includes a cylinder end attached to
cylinder 86, as just stated, and a rod end attached to pivot
bracket 54 via a second clevis joint.
[0024] Target 22 can be attached to posts 60, 62 with various types
of mounting hardware (not shown) and is sized in relation to
obstruction 16 so that it can be selectively concealed from and
presented to the shooter. Target 90 is a generally flat component
that preferably has target-related indicia on its surface, such as
those that conform with International Practical Shooting
Confederation (IPSC) guidelines. Furthermore, target 90 can be in
the shape of a person, animal, or some inanimate object, with one
or more zones indicating the quality of different shots, for
example.
[0025] During operation, drive mechanism 20 tilts target 22 between
generally coplanar concealed and presented positions. Beginning
with the concealed position shown in phantom lines, one of the two
air cylinders 84, 86 is extended and one is retracted (in this
particular embodiment the cylinder on the right is retracted and
the one on the left is extended, however, they could be reversed).
If the air cylinder 86 on the right is activated so that it
transitions from a retracted position to an extended position, then
both air cylinders will be in extended positions and movable target
holder 18 will be tilted to the `left presented` position shown in
solid lines. If, on the other hand, air cylinder 84 is activated,
then it would transition from an extended position to a retracted
position so that both air cylinders would be retracted. This
results in a `right presented` position that is not shown in the
drawings for reasons of figure clarity. It should be recognized
that throughout the range of motion that occurs when the apparatus
10 transitions between the various concealed and presented
positions, target 90 generally stays within a common plane.
[0026] Turning now to FIGS. 5-7, there is shown a second embodiment
110 of a shooting target apparatus that moves a target between one
of several generally coplanar positions; only this embodiment
utilizes a movable target holder employing a spring-loaded,
linkage-type construction instead of the titling arrangement
previously described. According to the embodiment shown here,
shooting target apparatus 110 generally includes a frame 114, an
obstruction 116, a movable target holder 118, a drive mechanism
120, and a target 122.
[0027] Frame 114 provides structural integrity to shooting target
apparatus 110, and preferably includes a base 128, a number of
mounting receptacles 130-136, a number of upright or vertical posts
138-144, and drive mechanism mounting brackets 146-150. As before,
the base 128 preferably includes a number of elongated, transverse
members that lie on the ground and provide a foundation for the
rest of the apparatus. As an example best seen in FIG. 7, the base
128 can have a configuration where a single, long frame component
is attached to a number of separate transverse members. Mounting
receptacles 130-136 respectively receive posts 138-144, which in
turn are used to support one or more obstruction panels. The drive
mechanism brackets maintain drive mechanism 120 in a generally
horizontal position that is elevated off of the ground and limit
the linkage members range of motion. They include a stop 146 the
prevents the linkage members from overextending, a cylinder mount
bracket 148, which is used to mount a pair of air cylinders and
provide drive mechanism 120 with a connection point, and an
anti-rotation plate 150. The anti-rotation plate is fixedly
attached to the frame 114 with small angle irons and keeps the air
cylinders of the drive mechanism from rotating. Anti-rotation plate
150 can also be used to mount optional switches, mechanical and/or
electrical, which can read and convey the position of the various
air cylinders. Its construction is somewhat similar to the
anti-rotation features previously explained.
[0028] Obstruction 116 protects the components of drive mechanism
120 and hides the target 122 when it is in a concealed position.
According to a preferred embodiment, the obstruction includes a
lower shield component 156, which may be comprised of a single
panel or multiple panels, and an upper shield component 158. Lower
shield 156 is secured to posts 138-144 by one of a number of
attachment techniques, while upper shield 158 is just secured to
posts 140-142, which are longer than posts 138 and 144 located on
the ends of the obstruction.
[0029] Movable target holder 118 uses a spring-loaded linkage-type
design to pivot the target 122 between one of several generally
coplanar positions, and generally includes a pair of linkage
members 166, 168, a cross member 170, a pair of posts 172, 174, and
a pair of springs 176, 178. Each of the linkage members 166, 168 is
pivotally attached to frame 114 at a lower end and cross member 170
at an upper end, and preferably use pivotal connection hardware
such as spacer plates, shoulder bolts, flange bearings, and thrust
washers. Cross member 170 is an elongated, horizontally aligned
component that extends the general width of the movable target
holder 118 and maintains a proper spacing between posts 172 and
174. Springs 176, 178 are diagonally attached across the linkage
members, and assist with the proper movement and spacing of the
movable target holder 118 during operation. Additional components,
such as stops or bumpers could be used to limit the range of motion
of the linkage members.
[0030] As with the previous embodiment, drive mechanism 120 uses a
pair of bi-directional, single-rod actuators or air cylinders to
move the target between the various coplanar positions, and
generally includes an air connection 186, valves 188, and a pair of
air cylinders 190, 192. The two air cylinders are connected in a
serial or end-to-end fashion and can drive the movable target
holder 118 between right presented, concealed, and left presented
positions, as previously described. Moreover, the rod end of air
cylinder 190 is securely attached to cylinder mount bracket 148,
and the rod end of air cylinder 192 is connected to linkage member
166. For each air cylinder connection requiring a pivoting motion,
it is preferable to use a clevis joint or some other type of
pivotal connection.
[0031] Target 122 is securely attached to posts 172, 174 so that it
can move together with the movable target holder 118. Because the
target 122 is similar to that already described, a second,
duplicate description has been omitted.
[0032] During operation, activation of drive mechanism 120 causes
movable target holder 118 to move between several coplanar
positions, as was the case with the previous embodiment. Beginning
with a concealed position (shown in phantom) where target 122 is
hidden behind obstruction 116, only one of the two air cylinders
190, 192 is extended (in this particular embodiment, air cylinder
190 is retracted and cylinder 192 is extended). If cylinder 190 is
activated, then it will go from a retracted position to an extended
position, this in turn causes the linkage members of movable target
holder 118 to pivot to the "left presented" position shown in solid
lines so that target 122 is visible to the shooter. Conversely, if
air cylinder 192 is activated, then it transitions from an extended
position to a retracted position so that both air cylinders are
retracted and the target 122 assumes a "right presented" position
(not shown).
[0033] It is to be understood that the foregoing description is not
a definition of the invention itself, but is a description of one
or more preferred exemplary embodiments of the invention. The
invention is not limited to the particular embodiment(s) disclosed
herein, but rather is defined solely by the claims below.
Furthermore, the statements contained in the foregoing description
relate to particular embodiments and are not to be construed as
limitations on the scope of the invention or on the definition of
terms used in the claims, except where a term or phrase is
expressly defined above. Various other embodiments and various
changes and modifications to the disclosed embodiment(s) will
become apparent to those skilled in the art. All such other
embodiments, changes, and modifications are intended to come within
the scope of the appended claims.
[0034] For instance, it is possible to replace the pneumatic drive
mechanism with another adapted power source, such as an electric
motor, a hydraulic drive mechanism, or some other drive mechanism
know to those skilled in the art. Furthermore, one or more
protective angle irons or other shielding-type components can be
added to any one of the shooting target embodiments to protect
their components from stray bullets. This is particularly useful
for protecting the components of the pneumatic drive mechanism,
although other components can and should be protected as well. Even
though most of the components described above are preferably made
of steel, they could alternatively be made of aluminum or another
metal, plastic, composite, wood, or any other suitable material
known to those skilled in the art, such as Amortex which is a
bullet proof material made of fiberglass and resins.
[0035] Furthermore, one of any number of additional features could
be added to any one of the embodiments described above. For
example, position sensing switches could be used throughout any one
of the shooting targets in order to provide an electronic
controller with feedback as to the position of one or more
components. It is also possible to use the shooting target in a
larger targeting system where some type of main control unit
communicates with each of the shooting targets so that they
function in a coordinated manner as the shooter advances through a
course. In that regard, the various shooting targets and the main
control unit may communicate via some type of wired medium or even
a wireless link. These are, of course, only some of the additional
features that may be used with any number of the embodiments
disclosed herein, as other features and aspects of the shooting
targets would be apparent to those skilled in the art. An
electrical connection 40 is located on the pivot arm and can
connect an electronic control system of the shooting target to
power and/or a larger control network.
[0036] In a preferred embodiment, software is used to randomly
activate one of the two air cylinders so that a shooter does not
know in which direction the target will be presented. The software
can provide at least two options for target presentation. One
option is to have the target advance either to the left or right
and stay in that position until the shooter advances through the
course. Another option is to have the target oscillate back and
forth while the shooter is at the shooting target until advancing
through the course.
[0037] As used in this specification and claims, the terms "for
example," "for instance," "such as," and "like", and the verbs
"comprising," "having," "including," and their other verb forms,
when used in conjunction with a listing of one or more components
or other items, are each to be construed as open-ended, meaning
that that the listing is not to be considered as excluding other,
additional components or items. Other terms are to be construed
using their broadest reasonable meaning unless they are used in a
context that requires a different interpretation.
