1. Field of the Invention
[0001] The invention relates to a laser target pointer, and more
particularly to the laser target pointer that can be assembled onto
a gun so as to provide an auxiliary aiming function to a gun
shooting path of the gun.
2. Description of the Prior Art
[0002] Except as a weapon that accelerates a bullet by exploding
gunpowder thereinside, the gun can be particularly structured for
recreations and/or games (a paintball gun or an air gun, for
example), and can be, but not limited to, pneumatically powered by
a compressed air bottle. In order to raise the shooting accuracy,
gun manufacturers have developed versatile laser target pointers
individually equipped onto a gun body of the gun for emitting a
laser beam to demonstrate a corresponding shooting path and
direction, such that an auxiliary aiming function can be provided.
However, existing laser target pointers still have many structural
shortcomings, such like: the adjustment mechanism of laser
alignment is complicated, the operation of functional buttons and
switches is inconvenient, the illumination distance or range of
invisible light is limited, the visibility of the functional menu
is not good, and etc. Thus, an improvement of the laser target
pointer to overcome the aforesaid shortcomings is definitely
necessary.

[0030] As shown in FIGS. 1A to 1C, FIG. 2A and. FIG. 2B, in a
preferred embodiment of the present invention, the laser target
pointer 1 comprises: a case 10, a laser module 20, a lighting
module 30, a magnetic switch with connecting cable 50, a power
module 60, an operating module (unnumbered), and an adjustment
mechanism 14.
[0031] The case 10 comprises: a main body 11, a lower cover 1.2 and
a front cover 13. The lower cover 12 is assembled and fixed under
the main body 11, while the front cover 13 is connected to a front
side of the main body 11 in a detachable manner. The power module
60 comprises at least a battery and is received inside the main
body 11. The front cover 13 is locked to the front side of the main
body 11 by a clipping mechanism 131. When the clipping mechanism
131 is unlocked, the front cover 13 can be detached from the main
body 11 in order to expose the at least one battery (power module
60) located in the main body 11 for battery replacement. The laser
module 20 and the adjustment mechanism 14 are located in the lower
cover 12, and are electrically connected to the power module 60
through an top-pressing circuit board 40. The top-pressing circuit
board 40 is provided with various electronic components for
controlling the laser target pointer 1. The laser target pointer 1
further comprises an adjustable fixing rack 15 disposed on a top
surface of the main body 11. The fixing rack 15 is for mounting the
laser target pointer 1 onto a carrier in a detachable manner. The
carrier can be, but not limited to, a pistols, rifle, paintball
gun, air gun or other carrier that can be connected by the fixing
rack 15. Since the front cover 13 is opened from the front side of
the case 10 to replace the battery, even when the laser target
pointer 1 of the present invention is mounted on a carrier (such
like a pistol 91 shown in FIG. 7A), the front cover 13 can still be
opened for replacing the battery without the need to remove the
laser target pointer 1 from the carrier first, which is very
convenient for battery replacement.
[0032] The lighting module 30 is located in the case 10 and
comprises at least one light emitting element 31, 32, and can emit
illumination light forwardly out from the case 10. The laser module
20 is located inside the lower cover 12 of the case 10 and
comprises at least one laser unit 22, and can emit laser beam
forwardly out from the case 10. The power module 60 is located
within the main body 11 of the case 10 and is electrically
connected to the lighting module 30 and the laser module 20 to
provide electric power to the at least one light emitting element
31, 32 and the at least one laser unit 22. The operating module is
electrically connected to the power module 60. The operating module
comprises at least one button 61 which can be pressed by user in
order to operate the power switch and other functions of the laser
target pointer 1.
[0033] As shown in FIG. 3A and FIG. 3B, the adjustment mechanism 14
is connected with the laser module 20, and can be used for
adjusting the position of the laser aiming point of laser beam
emitted by the at least one laser unit 22 of the laser module 20.
In this embodiment, the adjustment mechanism 14 comprises: a
biaxial pivoting mechanism 24, a first adjusting screw set and a
second adjusting screw set. One side surface of the laser module 20
is pivotally coupled to the biaxial pivoting mechanism 24, such
that the laser module 20 can use the biaxial pivoting mechanism 24
as a pivot to perform biaxial pivoting movements according to a
first axis and a second axis. The first adjusting screw set is
disposed on the side surface of the laser module 20 in such a
manner that, by rotating the first adjusting screw set, the side
surface of the laser module 20 will be pushed by the first
adjusting screw set to rotate around the first axis using the
biaxial pivoting mechanism 24 as a pivot. In addition, the second
adjusting screw set is disposed on a bottom surface of the laser
module 20 in such a manner that, by rotating the second adjusting
screw set, the bottom surface of the laser module 20 will be pushed
by the second adjusting screw set to rotate around the second axis
using the biaxial pivoting mechanism 24 as a pivot. Therefore, by
rotating the first adjusting screw set and the second adjusting
screw set, the laser module 20 can perform biaxial pivoting
movements using the biaxial pivoting mechanism 24 as a pivot, so as
to adjust the position of the laser aiming point of the laser beam
emitted by the at least one laser unit 22, and thus calibrate the
aiming accuracy of the laser beam as well as the bullet flight path
when the gun is shooting.
[0034] As shown in FIG. 3C, in this embodiment, the biaxial
pivoting mechanism 24 comprises: a fixed axis 241a and a sleeve
axis 242b. The fixed axis 241a extends along a first direction and
is fixed in the lower cover 12 of the case 10. The sleeve axis 242b
has a through hole extending in the first direction and a shaft
portion extending in a second direction, wherein the second
direction is perpendicular to the first direction. The through hole
of the sleeve axis 242b is sleeved on the fixed axis 241a in a
pivotable manner, so that the sleeve axis 242b can perform the
pivoting movement around the first axis about the fixed axis 241a.
The side surface of the laser module 20 is pivotally coupled to the
shaft portion of the sleeve axis 242b, so that the laser module 20
can perform the pivoting movement around the second axis about the
shaft portion of the sleeve axis 242b. In this embodiment, a shaft
hole is provided on the side surface of the laser module 20. The
shaft portion of the sleeve axis 242b passes through the shaft hole
from inside to outside so that the shaft portion and the through
hole are exposed outside the side surface of the laser module 20,
such that the fixed axis 241a penetrates into the through hole of
the sleeve axis 242b along the first direction, in addition, it
also allows the laser module 20 to pivot around the second axis by
using the shaft portion of the sleeve axis 242b as the pivot.
[0035] As shown in FIG. 3A and FIG. 3B, the first adjusting screw
set comprises a first screw 141a, a first pushing block 142a and a
first fixing ring 143a. By rotating the first screw 141a, the first
pushing block 142a can be driven to push the side surface of the
laser module 20 in order to cause the laser module 20 together with
the sleeve axis 242b to pivot around the first axis by using the
fixed axis 241a as the pivot. The first screw 141a has an internal
thread which is screwed with the outer thread of the first pushing
block 142a, therefore, when the first pushing block 142a cannot be
rotated due to restriction of the flat bottom groove 211, and there
is an external force tending to rotate the first screw 141a, the
rotational movement of the first screw 141a will drive the first
pushing block 142a to move linearly along the axial direction of
its thread. The first fixing ring 143a is used to position the
first screw 141a on the first screw hole 123 on the side surface of
the laser module 20, such that, when the first screw 141a is
rotated by an external force, the first screw 141a will be
positioned and restricted by the first fixing ring 143a and can
only perform a simple rotary motion without displacement forward
and backward along its axial direction. The second adjusting screw
set comprises a second screw 141b, a second pushing block 142b and
a second fixing ring 143b. By rotating the second screw 141b, the
second pushing block 142b can be driven to push the bottom surface
of the laser module 20 in order to cause the laser module 20 to
pivot around the second axis by using the shaft portion of the
sleeve axis 242b as the pivot. The second screw 141b has an
internal thread which is screwed with the outer thread of the
second pushing block 142b, therefore, when the second pushing block
142b cannot be rotated due to restriction of another flat bottom
groove (not shown in figures), and there is an external force
tending to rotate the second screw 141b, the rotational movement of
the second screw 141b will drive the second pushing block 142b to
move linearly along the axial direction of its thread. The second
fixing ring 143b is used to position the second screw 141b on the
second screw hole (not shown in figures) on the bottom surface of
the laser module 20, such that, when the second screw 141b is
rotated by an external force, the second screw 141b will be
positioned and restricted by the second fixing ring 143b and can
only perform a simple rotary motion without displacement forward
and backward along its axial direction. The adjustment mechanism 14
further comprises at least one position retaining element 25a, 25b,
which respectively abuts between the other side surface and the top
surface of the laser module 20 and the case 10. In this embodiment,
the position retaining elements 25a, 25b are conical coil springs,
which can provide elastic pushing forces to the other side surface
and the top surface of the laser module 20; that is, the position
retaining elements 25a, 25b can provide elastic pushing forces to
the laser module 20, so that the first pushing block 142a and the
second pushing block 142b can keep pressing against the laser
module 20, such that, when the first screw 141a and the second
screw 141b stop rotating by external forces, the position of the
laser module 20 can be maintained by the elastic pushing forces of
the position retaining elements 25a, 25b. Furthermore, a flat
bottom groove 211 extending along the first direction is formed on
the side surface of the laser module 20, in addition, the first
pushing block 142a has a square shape with a width substantially
matching the width of the flat bottom groove 211. The first pushing
block 142a is located in the flat bottom groove 211 and abuts
against the flat bottom groove 211; such that, when the first screw
141a is rotated by an external force, the first pushing block 142a
cannot be rotated due to the flat bottom groove 211. Therefore, the
rotational movement of the first screw 141a can be converted into a
linear displacement of the first pushing block 142a along the axial
direction of its thread, so as to achieve the purpose of pushing
the laser module 20 to adjust the position of its laser aiming
point. Similarly, the bottom surface of the laser module 20 also
has a flat bottom groove (not shown in figures) extending in the
second direction to restrict the second pushing block 142b from
rotating. It can be understood from the above descriptions that,
the biaxial pivoting mechanism 24 of the invention not only has the
advantages of simple structure and easy assembly, but also is very
simple in adjusting the position of the laser aiming point of the
laser beam emitted by the laser module 20; it does have improved
the shortcomings of the prior art laser modules whose position
adjustment mechanism is complicated in structure and difficult in
assembly.
[0036] As shown in FIG. 4 in companion with FIG. 2A, in this
embodiment, the magnetic switch with connecting cable 50 of the
laser target pointer 1 is magnetically and detachably connected to
a contact block 124 provided on a rear side of the lower cover 12
of the case 10 and is further electrically connected to the
top-pressing circuit board 40. The magnetic switch with connecting
cable 50 comprises: a magnetic attraction head 51, an operation box
52 and a connecting cable 53 extending and connecting between the
magnetic attraction head 51 and the operating box 52. The contact
block 124 is located in the lower cover 12 and comprises: a hollow
outer ring sleeve 512 fixed in the contact block 124, a ring magnet
513 fixed in the outer ring sleeve 512, a spacer 514 having a small
hole in the center, and a conductive post 515 inserted into the
small hole of the spacer 514 and having a front end of the
conductive post 515 to protrude out of the spacer 514. The spacer
514 has a non-conductive inner ring portion 5141 adjacent to the
small hole, and an electrically and magnetically conductive metal
outer ring portion 5142 surrounding the inner ring portion 5141.
The outer ring portion 5142 of the spacer 514 is attracted by the
magnetic force of the ring magnet 513 and contacts the ring magnet
513 in order to provide an electric conducting function. An
operation button 521 is provided on a top surface of the operation
box 52; in addition, a Velcro tape 522 (which can be one of a hook
surface or a loop surface) is provided on a bottom surface of the
operation box 52. The magnetic attraction head 51 has a container
structure furnished with electrically and magnetically conductive
components therein. When the magnetic attraction head 51 of the
magnetic switch with connecting cable 50 is magnetically attracted
by the ring magnet 513 and combined with the contact block 124, a
control signal can be generated and transmitted to the top-pressing
circuit board 40 by pressing the button 521 on the operation box
52, in order to perform the operation of turning on or off the
power supply of the laser target pointer 1 or activating a function
selected in advance. The power or function switch for controlling
the laser target pointer 1 can be extended away from the body of
the laser target pointer 1 and closer to the user's hand by the
connecting cable 53 and the operation box 52 of the magnetic switch
with connecting cable 50, which allows the user to conveniently
press the button 521 on the operation box 52 to operate and
activate the power or other pre-selected function of the laser
target pointer 1. In other words, according to the user's own
operating habits, the carrier (for example, the rifle 92 shown in
FIG. 7B) can be selectively pre-bundled with another Velcro tape at
a position close to the hand grip (or at a position convenient for
the user to operate); and then, the body of the laser target
pointer 1 can be assembled at the front end of the rifle 92 near
the barrel, while the operation box 52 of the magnetic switch with
connecting cable 50 can be bonded to the "another Velcro tape"
pre-bundled close to the hand grip of the carrier by using the
Velcro tape 522 provided on the bottom surface of the operation box
52. And then, the magnetic attraction head 5,1 of the magnetic
switch with connecting cable 50 can be magnetically attached to the
contact block 124 of the laser target pointer 1. In this way, the
user can easily and conveniently press the button 521 on the
operation box 52 with a finger (such as a thumb) without moving
his/her palm originally held on the hand grip of the carrier, so as
to operate and activate the power or other pre-selected function of
the laser target pointer 1. It can be understood from the above
description that, in the laser target pointer 1 of the present
invention, the operation box 52 of the magnetic switch with
connecting cable 50 can be attached on various locations of the
carrier (any location convenient for the user to operate) by
placing; such that, the power or pre-selected function of the laser
target pointer 1 can be conveniently turned on and off by operating
the button 521 on the operation box 52, and thus has improved the
shortcomings of the inconvenient operations of the function buttons
and/or power switches of the laser target pointer of the prior
art.
[0037] As shown in FIG. 1A, FIG. 1C, FIG. 2A, and in companion with
FIG. 3A, in this embodiment of the laser target pointer 1 of the
present invention, the laser units 22 of the laser module 20
includes a visible-light laser diode 221 and an invisible-light
laser diode 222 used for emitting visible laser beam and invisible
laser beam respectively, in which, the laser beams are emitted out
of the case 10 through the small holes 121 on the front side of the
lower cover 12. The rear ends of the visible-light laser diode 221
and the invisible-light laser diode 222 respectively have a
plurality of conductive pins 2211, 2221 which are soldered to a
connecting circuit board 23 located on the rear side of the laser
module 20, and then electrically connected to the top-pressing
circuit board 40 via the connecting circuit board 23. When the user
wishes to see the aiming point marked by the laser beam emitted by
the laser module 20 with naked eyes, the user can select and enable
the visible-light laser diode 221 to emit visible laser beam. When
the user is wearing night vision goggles and hopes that the laser
beam and its aiming point emitted by the laser module 20 can only
be seen through the night vision goggles and cannot be seen by
naked eyes, then the function of invisible-light laser diode 222
can be selected and turned on in order to emit invisible laser beam
(for example, but not limited to: infrared laser beam).
[0038] The at least one light emitting element 31, 32 of the
lighting module 30 includes a visible light emitting diode (light
emitting element 31) and a plurality of invisible light emitting
diodes (light emitting elements 32). The visible light emitting
diode (light emitting element 31) is located on the front cover 13
and is used to emit visible illumination light of greater power.
The plurality of invisible light emitting diodes (light emitting
elements 32) are respectively located on the lower cover 12 and the
front cover 13 and are used to emit invisible illumination light.
When the user wishes to see the objects illuminated by the
illumination light emitted by the lighting module 30 with his/her
naked eyes, he/she can select and turn on the function of visible
light illumination emitted by the visible light emitting diode
(light emitting element 31). When the user is wearing night vision
goggles and hopes that the objects illuminated by the lighting
module 30 can only be seen through the night vision goggles and
cannot be seen by naked eyes, then the function of invisible light
emitting diodes (light emitting elements 32) can be selected and
turned on in order to emit invisible illumination light (for
example, but not limited to: infrared illumination light). It is
well known in the art that, when the angle of divergence of the
illuminating light is greater, then the range of illumination that
can be clearly illuminated will be wider, but the distance of clear
illumination will be shorter. Vice versa, when the angle of
divergence of the illuminating light is smaller, then the range of
illumination that can be clearly illuminated will be narrower, but
the distance of clear illumination will be longer. Because in the
conventional technology of laser target pointer, one or several
invisible light emitting diodes (light-emitting elements) having
the same divergence angle are used to provide invisible
illumination light, such that the conventional laser target pointer
can only choose between a wide range of short-distance illumination
capability or a long-distance but narrow-range illumination
capability; it is impossible for the conventional laser target
pointer to provide both the wide range illumination and the
long-distance illumination capabilities. In contrast, in the
present invention, the divergence angles of the invisible
illumination light emitted by the plurality of invisible light
emitting diodes (light emitting elements 32) are different.
Therefore, it can meet the lighting requirements of different
illumination distances and divergent angles, so as to achieve the
advantages of both wide-range and long-distance illumination
capabilities. As shown in FIG. 5, the divergence angles of the
invisible illumination light emitted by the four invisible light
emitting diodes (light emitting elements 32) in the lighting module
30 of the laser target pointer 1 of the present creation are
different from each other, for example, but not limited to: 7-8
degrees, 15 degrees, 30 degrees, and 60 degrees. The effective
illumination range and distance of the invisible illumination light
emitted by each invisible light emitting diode (light emitting
element 32) are represented by the illumination ranges 3201, 3202,
3203, and 3204, respectively. That is, two of the invisible light
emitting diodes (light emitting elements 32) with light divergence
angles of 7 to 8 degrees and 15 degrees are for providing invisible
illumination light at longer distances and narrower ranges; in the
meantime, the other two invisible light emitting diodes (light
emitting elements 32) with light divergence angles of 30 degrees
and 60 degrees are used to provide invisible illumination light at
shorter distances but wider ranges. It can be seen from FIG. 5
that, the laser target pointer of the present invention provides a
plurality of invisible light emitting diodes; the divergence angles
of the invisible illumination light emitted by the invisible light
emitting diodes are different from each other, so as to meet the
lighting requirements of different irradiation distances and
ranges, and thus has improved the shortcomings of the restricted
illumination distance or range of the laser target pointer of the
prior art.
[0039] As shown in FIG. 6A and FIG. 6B, in this embodiment of the
laser target pointer 1 of the present invention, the operating
module is electrically connected to the top-pressing circuit board
40 and includes: a plurality of buttons 61 and a plurality of
patterns 70 which can be switched between a luminous status and a
darkness status. Each of the patterns 70 corresponds to at least
one operation function. By pressing one or more buttons 61, one or
some of the patterns 70 will be switched to the luminous status for
emitting light of a predetermined color in order to identify which
operation function or functions of the laser target pointer 1 are
currently enabled. Wherein, at least some of the patterns 70 can
emit at least two different colors of light, so that a single
pattern 70 can be used to identify at least two different operation
functions. In this embodiment, the plurality of buttons 61 are
provided on the lower cover 12. The plurality of patterns 70 are
arranged on a back cover of the main body 11 and comprise: an
illumination pattern 71, a lasing pattern 72, a power-on pattern 73
(FIRE), and an invisible light pattern 74 (ILLU). In which, when
the visible light operation is selected, the bright white light of
the illumination pattern 71 indicates that a visible light
illumination function of the lighting module 30 is selected. The
green light of the laser pattern 72 indicates that a visible laser
function of the laser module 20 is selected. Both the visible light
illumination function and the visible light laser function can be
selected independently, or both can be selected at the same time.
When performing invisible light operation selections, the red light
of the invisible light pattern 74 indicates that an invisible light
illumination function of the lighting module 30 is selected. The
orange light of the laser pattern 72 indicates that an invisible
laser function of the laser module 20 is selected. Both the
invisible light illumination function and the invisible light laser
function can be selected independently, or both can be selected at
the same time. The visible light illumination function and the
invisible light illumination function cannot be selected at the
same time; in addition, the visible laser function and the
invisible laser function cannot be selected at the same time. When
the power-on pattern 73 lights up in blue, it means that the
selected function(s) is/are being activated. In this embodiment,
the operation of pressing the button 521 on the operation box 52 of
the magnetic switch with connecting cable 50 is used to control
(turn on or off) the blue light of the power-on pattern 73, that
is, to control whether the selected function is activated or not.
Wherein, two sets of the patterns 70 are respectively provided on
the left half and the right half of the back cover, in addition,
two sets of buttons 61 are respectively provided on the left half
and the right half of the lower cover 12. In this way, different
users with a left-handed gun and a right-handed gun can
conveniently operate the buttons 61 and view the plurality of
patterns 70, which does improve the shortcoming of the poor
visibility of the function menu of the laser target pointer of the
prior art.
[0040] FIGS. 7A and 7B are schematic drawings respectively showing
the laser target pointer of the present invention being equipped on
a pistol and a rifle. It can be seen from FIG. 7A that, when the
laser target pointer 1 of the present invention is assembled on a
pistol 91 or other short gun, the back cover part of the main body
11 of the laser target pointer 1 will be very close to the trigger
of the pistol. For conventional laser target pointers in the arts,
the back cover of the laser target pointer is used to be opened for
replacing the battery; therefore, conventional laser target
pointers cannot replace the battery when they are installed on the
pistol. Instead, the conventional laser target pointers must be
removed from the pistol before the battery can be replaced, which
is very inconvenient. In contrast, since the laser target pointer 1
of the present invention is to replace the battery by opening the
front cover 13 from the front side of the case 10, therefore, even
if the laser target pointer 1 of the present invention is mounted
on the pistol 91 as shown in FIG. 7A, the battery (power module 60)
can still be replaced by directly opening the front cover 13
without the need to remove the laser target pointer 1 first, and
thus is very convenient. Moreover, it can be seen from FIG. 7B
that, when the laser target pointer 1 of the present invention is
assembled on a rifle 92 or other long guns, the location of the
laser target pointer 1 will be far away from another location where
the user generally holds the rifle/gun (such as the grip), and thus
is inconvenient for the user to directly operate the buttons 61
furnished on the case 10 of the laser target pointer 1. In
contrast, since the laser target pointer 1 of the present invention
includes a novel magnetic switch with connecting cable 50 whose
operation box 52 can be placed at any desirable position of the
carrier (rifle 92), for example, but not limited to, the grip or
any other user-friendly position as shown in FIG. 7B, the user can
press the button 521 on the operation box 52 to switch on or off
the power of the laser target pointer or other pre-selected
functions without releasing his/her hand from the grip of the
carrier (rifle 92), which does improve the shortcoming of the
inconvenient operation of the function buttons and switches of the
laser target pointer of the prior art.
[0041] While the present invention has been particularly shown and
described with reference to a preferred embodiment, it will be
understood by those skilled in the art that various changes in form
and detail may be without departing from the spirit and scope of
the present invention.
