DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present invention will be understood from the following detailed description of preferred embodiments, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features, methods, systems, procedures, components, circuits, and so on, are not described in detail.
One of the ways in which players amuse themselves in snow is throwing snowballs, one at the other, throwing snowballs at targets, objects, and so on.
The present invention is directed to a snow gun, which allows firing snow chunks towards an object such as a human individual, in a manner that does not jeopardize the object.
As mentioned above, the term snowball refers herein to a snow chunk, to be fired by a gun, and the term snowball gun refers herein to a gun for firing/throwing snowballs(s).
FIG. 1 is a front view pictorially illustrating a snowball gun, according to one embodiment of the invention.
FIG. 2 is a back view pictorially illustrating a snowball gun of FIG. 1.
FIG. 3 pictorially illustrates the snowball gun of FIG. 1, in which its magazine house 18 is open, and its magazine is separated from the house 18 thereof.
FIG. 4 is a sectioned view of the snowball gun of FIG. 1, which illustrates the throwing mechanism.
Each of FIGS. 5 a and 5 b is a side-sectioned view of a snowball gun according to one embodiment of the invention. In FIG. 5 a the gun is cocked. FIG. 5 b illustrates the gun after firing.
The snowball gun is marked herein by reference numeral 10. The outlook of the snowball gun illustrated in the figures herein is reminiscent of a Tommy gun, although the snowball gun fires single snowballs.
The user may use one or two gripping handles (12 and 12′) to hold the gun while firing, i.e., throwing snowballs.
In order to carry out a shot, the user thereof has to fill the magazine chambers with snow. He also may compress the snow in the magazine's chambers. Then he must pull cocking handle 16 backwards, thereby cocking a spring 34, until it is hooked at the end of the move. Handle 16 is connected to a piston 38. This mechanism is detailed in FIGS. 5 a and 5 b. Upon pulling trigger 14, the spring is released, thereby pushing a piston 38 into barrel 22 of the gun, resulting in propulsion of the snowball.
Spring 34 may be replaced by a rubber band, and so on.
After the shot has been carried out, the user pulls handle 16 again, i.e., cocks the gun. In this situation, the user rotates knob 50, attached to magazine 28, until the next chamber coincides with the gun's barrel.

The Shooting Mechanism

The basic structure of the shooting mechanism comprises:

- A barrel 22, through which a snowball passes when being shot, thereby directing the snowball towards a target.
  - Snowballs chambers 30 i, in which snowballs are disposed. The inner side of each snowball chamber is about the same size as the size of the inner side of the barrel. In order to be able to shoot, a snowball chamber has to be disposed in a shooting position, i.e., subsequently to the barrel such that the inner side of the barrel coincides with the inner side of the snowball chamber, thereby allowing the snowball present inside the snowball chamber to pass to the barrel.
  - A piston 38, for pushing the snowball present in the snowball chamber, through the barrel, then out of the barrel.
  - A propelling mechanism, for propelling the piston, thereby pushing the snowball out of the barrel. In the illustrated embodiment, the propelling mechanism is based on spring 34.
  - A cocking mechanism, for cocking the propelling mechanism; and
  - a triggering mechanism employing a trigger 14, for releasing the propelling mechanism from its cocked state, thereby pushing the snowball present in the snowball chamber that coincides with the barrel out of the barrel.

Thus, the snowballs are actually in the form of a cylinder.
As per the cocking mechanism, in the illustrated embodiment, the cocking mechanism comprises handle 16 connected to piston 38, and a hooking mechanism, for retaining the propelling mechanism, including the piston, cocked until released. More particularly to this embodiment, by pulling handle 16, spring 34 is tensed. Rod 26 is attached to the piston. The rod comprises a depression 32 at the end thereof. When handle 16 is pulled backwards, at a certain point ledge 36 meets depression 32, as illustrated in FIG. 5 a, thereby hooking the rod, which means retaining the gun cocked. Upon pulling trigger 14, ledge 36 separates from depression 32, thereby releasing the piston, which consequently moves as spring 34 is released, thereby firing snowball 40.
According to a further embodiment of the invention, the gun comprises a plurality of barrels. Of course, in this case the gun must be adapted to use a plurality of barrels.

The Magazine

In a further embodiment, the snowball gun comprises a magazine, which allows loading a plurality of bullets, rather than loading a single bullet each time.
The magazine is marked herein by reference numeral 28. The magazine is in the form of a cylinder, having a plurality of bullet chambers 30 i therein. The magazine is installed in the gun such that the rotation axis 54 of the magazine is parallel to the barrel's symmetry axis 52, such that by rotating the magazine around its rotation axis 54, at a certain point the inner side of a bullet chamber 30 i coincides with the inner side of barrel 22.
In order to refill the magazine with snowballs, according to one embodiment of the invention, the user takes the magazine out of the gun, fills the snowball chambers with snow, and puts the magazine back into the gun. According to another embodiment of the invention, the magazine is not separable. In this case, the user opens the magazine house, fills the exposed chambers with snow, and rotates the magazine in order to fill the other chambers with snow.
In the case of a separable magazine, a user may load several magazines in advance, thereby “shortening” the time required for replacing a magazine.
After a snowball is fired, a rotating mechanism is used for rotating the magazine until the next bullet chamber coincides with the barrel. The rotating mechanism may be based on electric motor 20 that rotates the magazine, or on mechanical elements, such as a handle or knob 50.
In the illustrated embodiment of the invention, the rotating mechanism comprises a knob 50, attached to magazine 28. Thus, by rotating knob 50, the magazine is also rotated. The user may indicate that the next bullet chamber coincides with the barrel by well known mechanisms therefor, a ball pushed by a spring towards a depression.
In an electric-driven rotating mechanism, the indication when a bullet chamber coincides with the barrel can be obtained by switches, and the like. Such mechanisms are also well known in the art.
In order to prevent snow from falling out of the bullet chambers of the magazine, a magazine house 18 can be used.
As mentioned above, in order to carry out a shot, a user thereof pulls cocking handle 16 backwards, thereby cocking a spring 34, until being hooked by a hooking mechanism. Upon pulling trigger 14, the hooking mechanism releases the spring, thereby allowing the spring to push piston 38 outwards. The relatively fast motion of the piston pushes the snowball out of barrel 22, i.e., the snowball is fired.
The characteristics of spring 34 in comparison to the size of the snowballs determine the shooting speed. Thus, the gun can be designed such that the shot would not jeopardize the target. Experiments carried out by the inventor of the present invention have shown that a snowball of about 60 mm diameter and about 60 mm length provides a projectile that leaves the barrel as a chunk, i.e., does not spread. Preferably, the propelling mechanism is adapted to launch a snowball at a speed that is about the same as the speed of a snowball thrown by a human individual, thereby not jeopardizing the target.
After firing a snowball, the magazine must be rotated until the next snowball chamber coincides with the barrel. Activating the rotation may be carried out in an automatic manner, i.e., consequently other action. For example, when using the electric motor for rotating the magazine, upon pulling handle 16, a switch closes a circuit that activates the magazine's rotation. The same effect may be obtained by mechanical means, such as in a revolver.
When the magazine rotation mechanism is rotated by electric power, the batteries 44 thereof may be stored in the guns' handle 12, as illustrated in FIG. 2.
