SHEET 30F 3 34 36 INVENTOR Albert Srubbmonn AGENT SPRING ACTUATED' PROJECTILE APPARATUS INCLUDING TARGET POCKETS FIELD OF THE INVENTION This invention relates generally to a game of skill and, in particular, is directedto a spring actuated device wherein marbles or'similar sized objects are propelled within a transparent, hollow hemisphere at suitable targets.

SUMMARY OF THE INVENTION spondingly identified target.

It is still another object of the invention to provide a skill game wherein projectiles are contained within .a transparent dome.

It is yet another object of 'the invention to provide a skill game wherein the course of travel of a marble or similar object can. be viewed after the marble is aimed and propelled toward a selected target in order to determine the accuracy of the manually controlled attempt to correctly project the object.

It is a further object 'of the invention to provide a skill game whereinthe flight path or progression of a marble or similar object propelled by a spring can be manually altered. I

It is a feature of the inventive skill game to have provisions for automatically monitoring and visibly registering each attempt to propel a marble or similarobject to come to rest at its designated target.

Briefly, according to a preferred embodiment of the invention, the game is in the form of a transparent hollow hemispherical dome mounted above and enclosing a concave circular disc having mounted thereon upstanding cups. A centrally located leaf spring is positioned beneath the underside of the disc to receive on '.its flat span one marble (of several) at a time through acentrally located opening in the disc. Manually actuated means, secured to the bottom of the platform, are

- parts which will be exemplified in the device hereinafter described in detail and of which the scope of application will be indicated in the appended claims; it being understood that changes in the precise embodiments of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

FIG. 5 is a top full sectional view of the toy taken along a line located as shown by line 5-5 of FIG. 4 particularly illustrating in plan view the projected configuration of the spring and its location in the toy.

DESCRIPTION OF THE PREFERRED I EMBODIMENTS The invention generally comprises a large transparent plastic hemispherically shaped dome mounted atop and enclosing a bowl-shaped container the base of the bowl-shaped container is concave downwardly in configuration. Several upstanding cups (targets) are secured to the base in spatial relationship to each other.

- era] marbles or objects of other shapes, such as cubes,

rings, or miniature footballs which normally rest on the base below the cups or other targets. The concave base has a central opening into which one of the objects is caused to roll or slide by gravity. The opening in the base is not large enough to admit more than one object at a time. A cylindrical sleeve integrally depends from a casing which surrounds the bowl-shaped container. A cylindrical piston, closed at its bottom end, is slidably received inside the sleeve and is mounted so that it can vertically reciprocate therein. The closed bottom of the piston normally projects below the lower edge of the sleeve. The rim, defining the open top end of the cylindrical piston, contacts the flat span of a horizontally positioned leaf (cricket) spring. The spring is movable by snap action between two positions. The central snap action portion of the flat span of the leaf spring 'is directly below'the opening of the base to receive and support the marble or similar object. At rest, the center portion of the horizontal span of the leaf spring which vreceives the marble is downwardly bowed. The spring is flexed by an upward movement of the piston relative to the sleeve against the flat span of the spring. As the rim of the upper, open end of the cylindrical piston is forced against the spring, the downwardly bowed center portion of the span of the spring is caused to snap into an upwardly bowed position. As the spring snaps into the upwardly bowed position, it thrusts the marbleor other projectile upwardly within the hollow hemis pherically dome in an arc shaped trajectory toward the target i.e., upstanding cup, basket, hook, etc. Each time the leaf spring is flexed, there is also actuated a mechanism which registers the number of repetitive attempts to successfully position the projectiles on the ber 18. The dome l2 and the bowl-shaped member 18 define a sufficiently large internal cavity for the projectiles 14 to be flipped towards the upstanding cupshaped targets 16 secured to the base 20 of the bowl 18. The bottom or base 20 of the bowl is in the shape of a slightly concave disc having a centrally located opening 22. The opening 22 in the base 20 is only large enough to admit one marble or other projectile 14 at a time. The marble to be propelled toward the target 16 is caused to roll by gravity on the concave disc and be received by the central opening in the disc.

The bowl-shaped member 18 is disposed snugly within an outer circular casing 24 and is positioned and secured against rotary motion by two vertically projecting pins 44 formed integral with the casing which projects through corresponding openings 46 in the base of the bowl member. The casing has a wall 26 which contacts and surrounds the wall of the bowl and which extends upwardly and terminates in a flange 28 which registers with the flange 30 of the hemispherically dome to form surfaces for sealing the dome to the casing and confining the bowl therein.

Depending integral with the casing 24 is a cylindrical sleeve 32 which slidably receives a piston 34. The lower end 36 of the said 34 is closed and the rim 38 defining the open upper end of the cylindrical piston contacts the leaf spring 40. The piston 34 is constructed with a radially outward extending collar 48 affixed to and encircling the piston. The collar 48 cooperates with a shoulder 50 on the casing to act as a stop to prevent the piston from completely separating from the sleeve. However, it is formed at a location vertically on the wall of the piston to permit adequate vertical motion of the piston to flex the spring and permit the spring to return to an unflexed configuration.

A leaf (cricket) spring 40 stands freely on the upper rim 38 of the piston 34 and is located centrally beneath the bowl shaped member 18. The cricket spring is'held in its central location by four lugs 42 formed integral with the casing and which project upwardly. The

cricket spring is formed from flat sheet metal resilient stock and has a rectangular-in-plan configuration. More specifically, the cricket spring is all of one piece and includes two opposed upwardly and outwardly diverging like

legs

52, 54 each of which extends from a line of angular bend 53 and terminates in a small outwardly, protruding substantially horizontal foot 56 which rests against the under surface of the bowlshaped member 18. Except for orientation, the spring is very similar to that disclosed in US. Pat. No. 3,356,369.

The span 58 of the cricket spring substantially closes the open end of the piston 34. The piston is vertically centered beneath the span of the cricket spring.

The span 58 has centered thereon and integral therewith a downwardly concave shallow circular depression 60 that is smaller in diameter than the span dimensions. On opposed sides of the depression and spaced therefrom are two outwardly diverging triangular shallow crowns 62. The span 58, depression 60, and crowns 62 jointly constitute the snap action position of the spring. When the span of the spring is urged upwardly by the upward movement of the piston relative to the sleeve, it is the centrally located concave portion of the spring supporting the marble in the centrally located opening in the base of the bowl which snaps or pops into a convex position and, in so doing, thrusts the overlying marble as a projectile toward the target.

A small rectangular vertical post 64 having a circular flat base 66 integral therewith rests on the span of the spring proximate one corner thereof. The post projects through an opening in the base of a U-shaped frame 68 on which is rotatably mounted a spur gear 70 affixed to a wheel 72. The upper end of the post is in contact with one of the teeth of the spur gear. The frame 68 is suitably secured to the base 20 and is contained in a casing 76 formed in said base.

In the idle position of the inventive toy, the cricket spring is depressed with the marble or other projectile freely non-constrainedly lying on the central circular depression of the span. The idle position of the toy is shown in FIG. 4 with the closed end of the piston projecting below the lower edge of the sleeve.

The toy is actuated by an upward thrust of the flat surface of the bottom of the piston by the fingers of the player as the entire toy is held in both hands. Alternatively, the toy can be actuated by placing it on a flat support and, with the palm of the hand on dome, pressingthe toy downwardly against the surface supporting the bottom of the piston. The sleeve guides the piston in its upward movement and as the piston moves upwardly, the rim of the piston transmits to the cricket spring the upward force applied to the piston.

Said upward force indicated by the arrow A in FIG. 4 flexes the cricket spring from its idle position to a position shown by the dot and dashed lines of FIG. 4 wherein the

legs

52 and 54 have slid on the undersurface of the base 20 of the bowl and spread further apart and the outward rotation of the legs has exerted torque couples on both sides of the span 58 so that the span begins to bow upwardly. When the cricket spring is stressed, so that its legs start to spread outwardly and its span bowed upwardly to a certain extent, the depression 60 on the span, initially downwardly concave or indented in a direction opposite to the direction A of initial movement of the spring, snaps, i.e., rapidly moves in said direction A of initial movement and thereupon reverses its configuration to flowingly merge into the upwardly bowed configuration of the span (dot, dash line of FIG. 4). When the central portion of the span is curved upwardly so as to merge into the bowed configuration of the remainder of the span, the triangular crowns 62 also substantially merge into the same configuration and a further stress is imposed thereon which is concentrated at the apices of the crowns adjacent the upwardly bowed center portion of the span.

The rapid upward movement of the indented central portion of the span throws the marble resting thereon upwardly but containedly within the dome and bowl toward the target 16.

By slightly tilting the toy, the direction of the flight of the marble can be controlled to some degree and,

hopefully, it can be cau'sed to fall and come to rest on p the target. The path of the marble during its movement toward the targetcan be observed through the transparent dome and suitable adjustment made in the angle at which the toy is tilted for each attempt to project the marble onto its target.

As the span of the spring is bowed upwardly to cause the central portion to snap into a convex configuration, the bowed span forces the post upwardly at a slight angle against the tooth of the span gear (as shown by the dot and dashed line of FIG. 4) and causes the gear to'rotate and drive the wheel through an increment of rotation. Located on the face of the wheel are indicia which are individually observed through the window 74 of the housing 76 enclosing and containing the gear, wheel and frame. The indicia show the number of the attempt (or success) of placing the marble-on target.

When the fingers at the base of the piston are relaxed, the internal stresses at the apecis of the crowns in the span are sufficient to trigger the cocked central portion of the span for snapping downward motion. That is to say, the central portion of the span is triggered into sudden return movement and is thereby rapidly thrust in the direction B of return movement of the prised of a rotatable wheel having indicia which may be observed through a small window in the topmost part of the outer casing 76 for the scoring device. Each increment of movement of the rotatable wheel of the scoring device registers a succeeding number to be observed through the window.

The skill game device as shown in the drawings is representative and has beendescribed and illustrated as a v, skill game for projecting marbles onto upstanding cupshaped targets. As will be readily recognized by those skilled in the art, many modifications of the devices are possible and yet within the spirit of the invention. For example, baskets or brackets mounted on the side wall of the hemispherical dome can be substituted for the upstanding cups and marbles simulating the design of basketballs can be employed. Alternatively, two baskets diametrically opposed representing the baskets at two ends of a basketball court may be employed and one marble used for two or more players to play a simu lated game of basketball. Similarly, the baskets can be replaced with small simulated football goal posts and in place of the marbles, a football may be used as the projectile.

It is also conceivable that the cup-shaped upstanding platforms as shown may be constructed so'as to have different heights above the disc and thus make the game more difficult when playing with marble projectiles. Alternatively, the marbles may .each be weighted off-center so as not to roll uniformly and thus make it even more difficult to correctly land or come to rest on the target.

Additionally, various color schemes and several more targets may be employed in order that a specific projectile be directed toward a correspondingly colored specific target.
