This invention is a toy projectile launcher that launches projectiles. The launcher includes a housing having an entrance and an exit in communication therewith to define a channel, a pair of flywheels supported by the housing and positioned about and in communication with the channel, and a pump handle for rotating the flywheels such that a projectile entering the channel may be engaged by the rotating flywheels and impelled through the channel and out through the exit.
Description
FIELD OF THE INVENTION
This invention relates generally to toy projectile launchers, and more particularly to a dual flywheel powered toy projectile launcher.
BACKGROUND OF THE INVENTION
Toy projectile launchers are well known in the art. These toys are suitably made for children and use harmless foam projectiles that are launched through the air. These launches may employ various spring loaded mechanism, such as disclosed in U.S. Pat. No. 5,711,285, which includes a pair of spring loaded launch tubes to separately launch projectiles. Other mechanisms such as disclosed in U.S. Pat. No. 5,791,326 employs compressed air. In addition thereto, flywheels or launching wheels have further been incorporated in these toys, such as the launching wheels disclosed in U.S. Pat. No. 5,471,967 or those employed in any self-pitching machine device.
In addition thereto, launching toys have developed various means for loading and firing multiple projectiles. For example: U.S. Pat. No. 5,988,152 discloses a toy gun that fires multiple projectiles with a single cycle of an actuation device, which is arranged to engage a spring that moves a reciprocating piston that fires the projectiles; and U.S. Pat. No. 5,711,285 mentioned above includes two launch tubes that separately launch projectiles.
Furthermore, the energy or power supplied by these toys to launch the projectiles is limited by the launching mechanisms. Launchers that utilize spring loaded mechanisms, pressurized air mechanisms and even some battery operated launching wheel mechanisms include a predetermined supply of energy. For instance, in a spring loaded mechanism the total amount of energy capable of being supplied to launch the projectile is determined from the spring, or in a battery operated launcher the total amount of energy is determined from the total output from the battery. A need therefore exists to provide projectile launchers that permit the user to control the amount of energy being supplied to launch the projectile. The user may then achieve a higher performance, meaning the user may launch the projectiles further then in a launcher that supplies a limited amount of energy.
In one such attempt, U.S. Pat. No. 5,611,321 discloses a ball launching device utilizing a self-propelled launching wheel to launch balls. As opposed to the above methods of supplying energy to the launching wheel, the '321 patent uses a hand pump to spin the launching wheel. As such, the users ability to repeat the spinning of the launching wheel at a faster rate will increase the launching velocity of the balls. As such a person with greater strength is capable of obtaining a higher or increase performance. However, the need still exists for improvements thereon. For instance, while the launching wheel may build up energy from repeated pumping, the energy drains quickly, since there is no means for storing this energy. Also, the incorporation of a single launching wheel will expel its energy quicker, then multiple wheels.
SUMMARY OF THE INVENTION
In accordance with the present invention, there is provided a toy projectile launcher having a housing that supports a handle, a launch channel, and a pump handle. The launch channel has an entrance and an exit, which permits a projectile to enter and exit therethrough. The projectile launcher includes a pair of flywheels that are in communication with and separately positioned on either side of the launch channel. The pump handle is slidably connected to the housing and is in communication with the pair of flywheels such that when the pump handle is moved inwardly the flywheels rotate. In addition, the projectile launcher includes a means for preventing a projectile positioned in the entrance opening from entering the launch channel and thus being launched, as well as including a triggering means for releasing the preventing means. As such, when a projectile is loaded in the entrance opening, a user gripping the handle must press the triggering means to move the projectile from the entrance opening to the launch channel. If the user has sufficiently rotated the flywheels, then the flywheels will engage the projectile entering the launch channel and impel it out of the exit opening.
Various shapes of projectiles are plausible, for instance the present invention includes a dart, glider and sphere. Because these darts have different shapes, the launch channel has an internal shape similar thereto, to permit the projectile to travel therethrough substantially unobstructed. In addition, the contour of the flywheels is substantially the same as the tip of the projectile, in order to adequately grip the tip of the projectile and launch it through the channel.
When the body of the projectile is larger than the tip, as in the glider, the flywheels further include grooves that permit the body of the projectile to travel therethrough substantially friction free. In yet other embodiment of the present invention, when the projectile launcher includes spheres, the launch channel may be pivotably attached to the housing, which permits the launched spheres to have a curved trajectory.
Numerous other advantages and features of the invention will become readily apparent from the following detailed description of the invention and the embodiments thereof, from the claims, and from the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
While the invention is susceptible to embodiments in many different forms, there are shown in the drawings and will be described herein, in detail, the preferred embodiments of the present invention. It should be understood, however, that the present disclosure is to be considered an exemplification of the principles of the invention and is not intended to limit the spirit or scope of the invention and/or claims of the embodiments illustrated.
Referring first to
FIG. 1
, a projectile launcher in accordance with one embodiment of the present invention is shown and generally referenced to as
10
. The projectile launcher
10
includes a housing
12
that supports a launch channel
14
having a entrance opening
16
and an exit opening
18
, through which foam darts
20
may be loaded and projected therethrough. The housing
12
may also support clips
24
for storing or holding extra darts
20
. Multiple darts may be loaded or stacked in a chute
26
that is in communication with the entrance opening
16
, providing a means for rapid or repeated firing of subsequent darts
20
. A handle
28
at one end of the projectile launcher
10
permits a user to hold and angle the projectile launcher
10
in a desired direction. As described in greater detail below, the projectile launcher
10
includes a pair of flywheels (not shown) housed in apertures
32
, which are separately positioned on either side of and in communication with the launch channel
14
. If a dart
20
is released into the launch channel
14
while the flywheels are rotating, the dart
20
is projected or launched through the exit
18
.
Referring now to
FIG. 2
, the projectile launcher
10
has a shaft
34
that accommodates a slidable pump handle
36
which is in communication with the flywheels
46
, such that by sliding the pump handle
36
inwardly (towards the other handle
28
) the flywheels
46
will rotate and energize. In greater detail, the pump handle
36
has a rack
38
that is in engagement with a slider gear
40
. When the pump handle
36
is moved inwardly, the rack
38
will move the slider gear
40
such that it engages a transfer gear
42
. Continued movement of the pump handle
36
inwardly causes the slider gear
40
to rotate the transfer gear
42
, which will rotate a combo gear
44
that is in communication with the pair of flywheels
46
separately located in the apertures
32
. As such, the rotation of the transfer gear
42
rotates and energizes the flywheels
46
. When the pump handle
36
is moved away from the handle
26
(defined as moving outwardly), the rack
38
moves the slider gear
40
into an idle position, such that the slider gear
40
is no longer in engagement with the transfer gear
42
. Moving the pump handle
36
inwardly and outwardly repeatedly keeps the flywheels
46
rotating such that the energy being stored is greater to or equal to the energy being expelled, thus maximizing the energy which will be transferred to the dart
20
, when the dart is moved from the entrance opening
16
to the launch channel
14
.
The projectile launcher
10
further has the means to prevent a dart
20
from entering the launch channel
14
; this will prevent the dart
20
from launching until the user has sufficiently energized the flywheels
46
. When the flywheels
46
are sufficiently energized or rotating, the user may release the preventing means by pressing a trigger means
30
located on the handle
28
. By pressing the trigger means
30
, the user will release the preventing means and cause a dart
20
positioned in the entrance opening
16
to move into the launch channel
14
, which will then be engaged by the rotating flywheels
46
and launched out of the exit opening
18
.
The trigger means
30
includes a trigger
48
that is pivotally attached to the housing
12
and is outwardly biased by a return spring
50
. A hammer
52
also attached to the trigger
48
will move outwardly when the trigger
48
is pressed inwardly. Upon releasing the trigger
48
, the return spring
50
will bias the trigger
48
outwardly, returning the hammer
52
to its initial position. The hammer
52
is attached to a retaining arm
54
that initially prevents the dart
20
from entering the launch channel
14
. However, when the hammer
52
moves outwardly, it pushes the retaining arm
54
. The retaining arm
54
being positioned in a guide slot
56
will be guided downwardly away from the dart
20
when pushed by the hammer
52
. As such, the dart
20
will be free to enter the launch channel
14
.
Referring now to
FIGS. 3
a
through
3
c
, it is shown that when the trigger means
30
is pressed, the hammer
52
pushes the retaining arm
54
within the guide slot
56
away from the dart
20
. As such, a dart
20
may move from the entrance opening
16
to the launch channel
14
. In order to make sure the flywheels
46
engage the first dart
20
, the hammer
52
also pushes the dart
20
forwards into the flywheels
46
. When the hammer
52
pushes the dart
20
forwards, the top portion
53
of the hammer
52
also moves under a subsequent dart
21
positioned above the dart
20
, preventing the subsequent dart
21
from entering the entrance opening
16
and being launched by the projectile launcher
10
. However, when the trigger means
30
is released the hammer
52
resets and the subsequent dart
21
moves into position, such that if the flywheels
46
have been sufficiently energized, a user may fire the subsequent dart
21
or multiple darts without having to re-pump or re-energize the flywheels
46
.
From a top view (
FIG. 3
b
) it is shown that the dart
20
has moved such that the tip
58
of the dart
20
has engaged the rotating flywheels
46
. The flywheels
46
further include a contour
47
that is configured to match the shape of the tip
58
, shown in
FIG. 3
c
. The dart
20
also includes a body
59
that is smaller than the tip
58
such that the body
59
of the dart
20
passes through the flywheels
46
substantially friction free. The contour
47
of the flywheels
46
is such that the flywheels
46
will sufficiently grip only the tip
58
of the dart
20
, therefore launching the dart
20
through the launch channel
14
.
Referring now to
FIGS. 4
a
and
4
b
, in another embodiment of the present invention, a projectile launcher
60
may be similarly configured but equipped to receive gliders
62
. A launch channel
64
would include a wider opening so the wings
63
and tail of the glider
62
will not be obstructed. It is further noted that the flywheels
68
are rotated and energized in the manner stated above. Turning to
FIGS. 4
b
and
5
a
and
5
b
, it is shown that the flywheels
68
include grooves
66
that permit the passage of the wings
63
through the flywheels
68
substantially friction free. In addition, the contour
69
of the flywheels
68
is configured such that the flywheels
68
engage the tip
65
of the gliders
62
.
Referring now to
FIG. 6
, in yet another embodiment of the present invention, a projectile launcher
70
is equipped to launch spheres
72
. The projectile launcher
70
includes a launch channel
74
that includes an entrance and an exit opening
76
and
78
, respectively. Multiple spheres
72
may be loaded through a chute
80
that is in communication with the entrance opening
76
and additional spheres
72
may be stored in clips
82
located on the projectile launcher
70
. A pair of flywheels
86
is supported in apertures
88
, which are located on either side of and are in communication with the launch channel
74
. A handle
90
is also provided with a triggering means
92
, which when pressed moves a sphere
72
or allows it to move from the entrance opening
76
to the launch channel
74
, such that when the flywheels
86
are rotating (in a manner similar to the aforementioned embodiments) the sphere
72
may be projected out of the exit opening
76
. In addition, when the triggering means
92
is pressed a second or subsequent sphere is prevented from entering the entrance opening
76
until the triggering means
92
is released and pressed again. It should also be noted, that the contour of the flywheels
86
are configured to the shape of the spheres
72
such that when the sphere
72
is dropped or moved into position the flywheels
86
engage and impel the spheres
72
.
Referring now to
FIGS. 7
a
to
7
c
, the projectile launcher
70
includes a launch channel
95
that may be pivotably connected to the projectile launcher
70
. As shown in
FIGS. 7
a
to
7
c
, the pivotable launch channel
95
may pivot either to the left (
FIG. 7
a
) or to the right (
FIG. 7
c
). The flywheels
86
spinning at the same rate will always launch a sphere in a straight direction, indicated by arrow
97
. But if the pivotable launch channel
95
is pivoted to the left, the sphere
72
will come into contact with the right wall
96
a
of the launch channel
95
, which will impart a right spin on the sphere, such that when the sphere
72
exits, the trajectory of the sphere
72
will curve to the right. Consistent thereto, if the pivotable launch channel
95
is pivoted to the right, the sphere
72
will come into contact with the left wall
96
b
of the launch channel
95
, which will impart a left spin on the sphere, such that when the sphere
72
exists, the trajectory of the sphere
72
will curve to the left. Also, when the launch channel
95
is pivoted to the center, the trajectory of the sphere
72
exiting the launch channel
95
will be straight, as the sphere should exist substantially unobstructed.
From the foregoing and as mentioned above, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the novel concept of the invention. It is to be understood that no limitation with respect to the specific methods and apparatus illustrated herein is intended or should be inferred. It is, of course, intended to cover by the appended claims all such modifications as fall within the scope of the claims.
