Harper, George W. Lescher, and George W. Dunbar, Nashville, Tenn., assignors to Kusan, Inc., Nashville, Tenn., a corporation of Kentucky Filed May 20, 1964, Ser. No. 368,909 14 Claims. (Cl. 124-29) This invention relates generally to toy firearms of the cannon or mortar type and more particularly to such a toy which can mechanically fire a harmless projectile.

Toy firearms of this type are known in the art but are usually characterized by one or more undesirable features. Among these are: a danger of harm to children from the projecting means employed or from the force and nature of the projectile; a difficulty of manipulation so as to result in an early lack of interest therein by a child; a lack of sturdiness so as to result in early breakage of the firearm or its missile-ejecting mechanism; an excessive cost where a realistic simulation of a firearm is embodied; and a complexity of design resulting in impractical manufacturing, assembling and packaging costs.

Accordingly the main object of the present invention is to provide an improved toy firearm of the mortar type which will obviate the above and other undesirable features characterizing known structures.

An important object of the present invention is to provide an improved toy mortar which will mechanically fire a light resilient projectile such as a ball in a vertically arched trajectory with unusually high efficiency and per formance.

Another important object of the present invention is to provide an improved toy mortar wherein the angle of the initial trajectory may be readily varied to thereby educationally instruct children in the effects resulting therefrom as to range and angle of the final trajectory during their play.

A further important object of the present invention is to provide an improved toy firearm of the type described which comprises a projectile receiving barrel and spring actuated projectile ejection or propulsion means formed of complementary rigidly joined barrel halves each including complementary and cooperating portions forming a projectile support and guides and reactive surfaces for the propulsion means, the spring actuated plunger being movable in said complementary guides to forcibly engage and eject the projectile from the barrel which is supported by its lower end and provided with an intermediate barrel-angle-adjusting support.

A still further important object of the present invention is to provide an improved toy firearm which is simple of construction, rugged and of long life in use, and susceptible of ready and economic manufacture.

Other objects and advantages of the invention will become apparent during the course of the following description.

In the drawings we have shown two embodiments of the invention, in these showings:

ice

FIGURE 8 is a fragmentary elevational view of the inner side of one of the complementary halves of a modified form of the toy firearm;

FIGURE 9 is a transverse sectional view thereof taken on the line 9-9 of FIGURE 8;

FIGURE 10 is a top plan view of a modified form of the plunger; and

FIGURE 11 is an end elevational view thereof.

Referring to FIGURES 1 to 7 of the drawings, numeral 15 designates the toy firearm as a whole which comprises a pair of identical but symmetrically opposite complementary halves 17 and 18 of a suitable plastic such as polystyrene, rigidly joined as by gluing or heat fusion along the central longitudinal vertical plane of the firearm 15 which simulates a mortar, an intermediate support 20, and a restraining device 22 adjustably connecting the base of the mortar 15 and the support 20.

Since the two longitudinal and complementary halves 17 and 13 are identical, only one need be described in detail. Each half includes a barrel portion 24 having an intermediate, inner semi-circular strengthening rib 25 and being substantially closed at its inner end by a bulkhead 26 (FIGURE 5), the barrel otherwise opening into and being angularly disposed to the base 27 of the mortar 15, the outer base contour being arcuate as shown at 28 (FIGURES 1-4).

The bulkhead 26 is provided with a strengthening rib 30, a semi-circular slot 32 and a rectangular slot 33 which defines a latch or trigger holding member 34 as will be further described. Adjacent the bulkhead, the barrel is formed with a longitudinally extending gun-sight-simulating shoulder 35, the inner surface 36 of which functions as a guide for the spring actuated plunger. The barrel 24 is also provided in its side with a longitudinally extending slot 37 which terminates at its forward end in an enlarged rectangular portion 38 in which a cushioning means 40 such as rubber is permanently mounted.

The mortar half 17 is provide with a lug 42 having a bayonet-type aperture 43 and both of the halves are provided with journal members 44, 45 for the reception of hub portions 46, 47 formed at the upper ends of the webconnected legs 48 of the intermediate support 20. The web 50 is also provided with a bayonet-type aperture 51 and it will be apparent that different lengths of the restraining device 22, which may be a beaded chain as shown, may be secured in the bayonet apertures 43, 51 so as to adjust the angularity of the intermediate support 20 and hence the vertical angularity of the barrel 24 of the toy firearm 15 and hence the trajectory of the missile to be fired or ejected therefrom.

As disclosed in FIGURES 6 and 7, a rodlike plunger 54 having a missile engaging and ejecting head 55 and two pairs of axially spaced, laterally projecting shoulders 56, 57 whose ends 58 engage the inner sides of the slots 37 as guides, is provided with a pair of enlarged laterally extending cocking wings 59 with finger recesses 60 formed in their forward edges which cooperate with laterally projecting, fixed finger lugs 61 to facilitate the cocking movement. A combined latch and trigger member 62 extends upwardly and rearwardly from the cocking wings 59 and terminates in an inclined trigger surface 63 which, in the cocking operation, deflects it under the latch holding member 34 which is then latchably engaged by its forward vertical face 64.

As indicated in FIGURES 3 and 4 of the drawings, the complementary halves 17 and 18 are assembled in perfect, cooperating alignment by means of spaced holes and mating pins 65. Prior to such assembly, a compression spring 67 is slipped over the rodlike plunger 54 which is extended through and guided at its aft end in its reciprocal movement in the mortar 15 by the-aperture formed by the two cooperating semi-circular slots 32 in the bulkheads of the two halves 17, 18. Similarly, the inner surfaces 36 of the shoulders 35 of the two mortar halves guide and bear against the side faces of the combined trigger latch 63, 64, the two rectangular notches 33 of the halves defining the opening through which the trigger latch passes.

It will now be readily apparent that assembly of the toy firearm or mortar comprising the present invention is readily and simply effected by placing the spring 67 over the plunger 54, inserting a cocking wing 59 through its corresponding slot in a barrel half 17 or 18, and laying the aft or inner end of the plunger in the semi-circular slot 32 where it will be lightly held by the engagement of the inner end of the spring against the outer face of the bulkhead 26 surrounding the slot. The other barrel half is now placed over the other cocking wing 59 by its guide slot 37 and the mating holes and pins 65 interfitted so as to align and permanently connect the halves 17 18 into an integral unit.

In operation, to prepare the mortar for firing or ejection of a missile, the cocking wings 59 and finger lugs 61 are squeezed by the fingers to retract the plunger 54 against the action of the spring 67 until the trigger 63 is deflected downwardly by the latch holding member 34 and passes it to allow the trigger 63 to spring upwardly with its latch face 64 engaging the member 34. This is the cocked or ready to fire position.

At this time, or prior to the cocking step, a missile may be dropped into the barrel. This should preferably be of only slightly less diameter than the mortar barrel so that it is supported in firing position therein by the circular rib 25 where it will be struck by the plunger head 55 when the mortar is fired. Desirably, the missile comprises a harmless, resilient, spherical hollow ball such as a ping pong ball.

The angle of inclination of the intermediate support 20 is adjusted to obtain the desired missile trajectory and the mortar is then aimed at the desired target. To fire the mortar (effect the ejection of the missile), the trigger 63 is depressed until it clears the holding member 34 upon which the spring 67 rapidly forces the guided plunger forwardly so that the head 55 forcibly strikes the missile to eject it from the barrel.

The plunger is arrested at the end of its firing movement forwardly or outwardly by the contact of the forward edges of the cocking wings 59 with the cushion members 40 in the forward ends 38 of the guide slots 37, which effectively absorb the deceleration energy so as to avoid shock damage to the toy over a long period of use.

A modified form of the cushioning members is disclosed in FIGURES 8 to 11 wherein parts similar to those of the just described embodiment bear similar numerals. In the modified form, the cushion members 40 are dispensed with and the plunger 54 is provided with a circular bumper 70 spaced axially rearwardly of and larger than the plunger head 55.

As shown in FIGURES 8 and 9, each of the halves 17, 18 of the toy firearm 15 is provided at a point rearwardly spaced from the missile supporting ribs 25, with transversely disposed quadrant sections or leaves 73, 72 which are spaced from each other as at 74 to permit passage therebetween of the cocking wings 59. The radially inner edge portions of the quadrant leaves are arcuate and unsupported to define a circular opening (when the halves 17, 18 are assembled) for the passage of the bumper 70 which is of slightly greater diameter than the opening.

The leaves 72, 73 being of plastic, their inner unsupported edges are slightly flexible so that when struck by the bumper 7 when the mortar 15 is fired, they absorb a substantial part of the deceleration energy of the plunger. The remaining energy is absorbed by the ends 38 of the slots 37 when struck by the forward edges of the cocking wings 59. Thus, either form of deceleration energy absorber is highly effective in preventing breakage of the barrel and in ensuring long life of the toy.

It is to be understood that the forms of our invention herewith shown and described are to be taken as preferred examples of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departure from the spirit of the invention or the scope of the subjoined claims.
