hollow cylinder provided at the forward end thereof with a nozzle
and being operatively mounted for sliding movement within the gun
between a first position wherein the nozzle is positioned
rearwardly of that part of the chamber into which the pellets are
fed and a second position wherein the nozzle extends within the
barrel of the gun, the cylinder normally being urged to its second
position by a spring, a piston mounted within the cylinder, the
inoperative position of a trigger mechanism formed as a part of the
gun holding the piston in its rearward position, the piston
normally being urged to move forwardly within the cylinder and a
slide mechanism operatively mounted to the gun such that as the
child moves same rearwardly, the cylinder is caused to move
rearwardly eventually contacting and forcing the piston rearwardly
to its cocked position, after which the cylinder returns to its
forward position moving a pellet introduced from the magazine into
the chamber of the gun, after which actuation of the trigger
mechanism releases the piston to move forwardly within the cylinder
forcing air normally contained therein outwardly through the nozzle
causing the pellet to be propelled out of the barrel of the
gun.

Description
BACKGROUND OF THE INVENTION
The present invention relates generally to toy guns wherein air is
used to propel a harmless pellet. The present invention is
characterized by its simplicity in construction, reliability of use
and safety standards.
SUMMARY OF THE INVENTION
The toy air gun of the present invention is designed to stimulate
the amusement of the child by permitting harmless pellets contained
within a detachably mounted magazine to be automatically and
sequentially raised into the chamber of the gun by pumping a slide
action mechanism. Air, forced from a cylinder and accelerated
through a nozzle, is used to propel the harmless pellets. More
specifically, a hollow cylinder provided at its forward end with a
nozzle is mounted for sliding movement within the gun casing. A
hollow piston, in turn, is slidably mounted within the cylinder.
The hollow piston is mounted about an elongated guide located
within the gun casing and a spring is positioned between the guide
and the piston for the purpose of normally urging the piston
forwardly within the cylinder. As the slide mechanism of the gun is
pulled rearwardly by the child, the cylinder is forced backwardly
into engagement with the piston which, in turn, is forced
rearwardly until fixedly secured by the action of a latch mechanism
formed as an integral part of the trigger mechanism. As the slide
lever is released, the cylinder is urged forwardly by a spring
until the nozzle thereof contacts the uppermost pellet, which has
automatically been delivered to the chamber, thereafter forcing
same into the barrel of the gun. As the trigger is pulled, the
piston lurches forward expelling the air within the cylinder
through the reduced nozzle, at which time the resulting jet of air
contacts the pellet propelling same forwardly through the barrel.
Not only does the present invention simplify construction and
operation of the gun, but, moreover, insures that only a
predetermined amount of air can be expelled from the cylinder thus
insuring that the length of flight of the pellet which is, of
course, of the utmost importance when considered from a safety
standpoint, is uniform. The pellets are soft plastic and are
provided rearwardly with hollow portions into which the jet of air
is directed.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a side elevational view of the toy air gun illustrating
the casing, barrel, trigger group, stock, slide mechanism and
magazine;
FIG. 2 is a side elevational view of a portion of the toy air gun
with part of its casing removed so as to expose the position of the
component parts after a pellet has been propelled;
FIG. 3 is a side elevational view of a portion of the toy air gun
with part of its casing removed illustrating the position of the
component parts as the slide mechanism is moved rearwardly causing
the cylinder to engage and eventually move the piston rearwardly
until the latter is locked by the latching mechanism of the
trigger;
FIG. 4 is a side elevational view of a portion of the toy air gun
with part of its casing removed illustrating the position of the
component parts after the piston has been cocked and the hollow
cylinder and discharge nozzle have moved forwardly under the force
of a restoring spring, it being apparent that the nozzle is thus
caused to move the uppermost pellet into position within the
barrel, it further being understood that actuation of the trigger
mechanism causes the piston to move forwardly eventually assuming
the position illustrated in FIG. 2 at which time air within the
cylinder is expelled through the discharge nozzle propelling the
pellet through the barrel; and
FIG. 5 is an exploded perspective view illustrating the uppermost
portion of the magazine which is detachably mounted within a
receiving section mounted within the gun casing.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The toy air gun is designated generally by the reference numeral 10
in FIG. 1 and comprises a casing 12 within which a barrel 14 is
mounted. The stock 16 is appropriately secured to the casing 12.
The reference numeral 18 designates generally the trigger
mechanism. Detachably mounted to the casing 12 is a magazine 20
containing a plurality of harmless pellets 72 normally urged
upwardly by the force of a spring. Mounted forwardly of the casing
for pumping action is the slide mechanism 26. Movement of the slide
mechanism 26 rearwardly automatically cocks the gun while
introducing the uppermost of the pellets 22 into the chamber, as
explained in detail hereinafter.
Turning now to FIG. 2, the reference numeral 28 designates a
hollow, plastic cylinder provided forwardly with a discharge nozzle
30 of reduced dimension. When the gun is inoperative, the forward
end of the nozzle 30 protrudes within the rearward end of the
barrel 14. The cylinder 28 is provided with a downwardly extending
flange 32 having a support 34 around which one end of a spring 36
is secured. The other end of the spring 36 is secured to a support
38 formed as an integral part of the magazine receiving section 39
of the casing 12. As will be apparent, the spring 36 normally urges
the cylinder 28 forwardly to the position illustrated in FIG.
2.
Operatively connected to the flange 32 of the cylinder 28 is a rod
40 terminating at its forward end in a block 42 suitably secured
within the walls of the slide mechanism 26. As will be apparent,
the slide mechanism 26 is provided with arms 44 extending within
the slots 46 formed within the casing 12. Thus, as the slide
mechanism 26 is pulled rearwardly by the child, the rod 40 moves
rearwardly forcing the cylinder 28 to move rearwardly against the
force of the spring 36.
A hollow, plastic piston 48 is slidably mounted within the interior
of the cylinder 28 and terminates forwardly in a flat wall 50. The
hollow piston 48 is mounted around a guide member 52 formed as an
integral part of the casing 12. Interposed between the forward end
of the guide 52 and the wall 50 of the piston 48 is a spring 54
which normally urges the piston 48 forward. The piston 48 is also
provided with a depending flange 56 provided with an opening 58,
the purpose of which will be described hereinafter.
The trigger mechanism or group 18 comprises a one-piece lever 60
mounted to rotate about an integrally formed shaft 62 appropriately
journalled within the casing 12. Opposite the trigger finger
configuration in the lever 60 is a latching element 64. The spring
66 is secured at one end to a support 68 formed as a part of the
lever 60 and at the other end thereof to a shaft 70 secured to the
casing 12. In this manner, the lever 60 is urged to move
counterclockwise about the shaft 62 so that the trigger
configuration is moved forwardly within its associated housing.
As will now be apparent, and as illustrated in FIG. 3, as the slide
lever 26 is moved rearwardly, the cylinder 28 moves rearwardly
engaging the piston 48 moving same rearwardly until the latching
element 64 is forced through the opening 58 at which time the
piston 48 is fixedly secured in its cocked position. Note that the
discharge nozzle 30 has been withdrawn from the barrel 14.
Thereafter, and as illustrated in FIG. 4, the slide lever 26 is
released at which time the force of the spring 36 causes the
cylinder 28 to return to its original position. During the return
movement of the discharge nozzle 30, the uppermost positioned
pellet 72 is moved forwardly into the rearward section of the
barrel 14, the operation of the magazine 20 and its receiving
section 39 to be explained hereinafter.
Thereafter, the trigger mechanism 18 is actuated in the usual
manner, rotating the latching element 64 clockwise so as to release
the cocked piston 48. The piston 48 lurches forward under the
influence of the spring 54. Thus, air normally within the cylinder
28 is expelled therefrom through the discharge nozzle 30. As will
be apparent, the restricted area of the nozzle converges the air
causing same to jet outwardly.
Each of the pellets 72, which are made of any soft material, is
provided rearwardly with a generally hollow cone-shaped portion 74
into which the jetting air is directed, thus providing maximum and
uniform impact.
Turning now to FIG. 5, it is noted that the magazine receiving
section 39 is integrally fitted within the casing 12. In the top of
the section 39 is formed a generally cylindrical opening into which
the rearward end of the barrel 14 extends, as seen for example in
FIG. 4. The discharge nozzle 30 of the cylinder 28 is free to slide
within the cylindrical opening of the receiving section 39.
A slot 76 is provided within the side wall of the section 39 while
the magazine 20 is formed with complementary guides 78, thus
permitting the magazine 20 to be pushed upwardly within the
receiving section 39. Eventually, the intermediate side wall 80
flexes outwardly as the top portion 82 thereof abuts and is pushed
outwardly from the downwardly extending flange 84 of the receiving
section 39, thus resiliently locking the magazine 20 within the
receiving section 39. The pellets 72 are loaded on top of the
surface 86 below and against which the spring 71 presses. As a
pellet 72 is loaded and pushed downwardly, the top portion 82
normally restrains the pellet from moving upwardly. As the magazine
is inserted within the receiving section, the top portion 82 is
flexed outwardly, as previously explained, thus permitting the
pellets 72 to move upwardly under the influence of the spring 71 as
soon as the discharge nozzle 30 is withdrawn to the position
illustrated in FIG. 3. The resilient flap 90 forming the top of the
section 39 bears gently against the pellet 72 until it is moved
forward into the rearward section of the barrel 14, as illustrated
in FIG. 4.
