DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now by reference characters to the drawing which illustrates the preferred embodiment of the present invention, A generally indicates a rocket-simulative toy or amusement device which comprises a projectile or rocket element 1, being of general cylindrical, tubular character, having a sidewall 2 and an outer end wall which may be rounded, as at 3. The said projectile 1 is open at its lower end, as at 4, and internally is provided with a coaxial hollow piston 5 being closed at its outer end, as at 6, and with its inner open end terminating spacedly from the end margin of the open end 4 of said projectile 1. Projectile I is preferably unitarily formed of a suitable plastic material having limited resiliency for purposes presently appearing. On its exterior surface, projectile 1 may be provided with a plurality of circumfercntially spaced-apart shallow extensions, as at 7,7, to provide manipulating surfaces.

Said toy A also includes a launching base 8 being also formed of suitable plastic material with limited resiliency and being of general cylindrical character having an upstanding sidewall 9 for disposition of the base margin 10 thereof upon a suitable support surface, such as a table or the like, and there being a top planar wall 11. Thus, for economy in production, launching base 8 may be hollow, with its lower end open (see FIG. 5). Projecting circumferentially of sidewall 9 proximate top wall 11 is a continuous, relatively shallow flange 12 for purposes presently to be described. Projecting from the center of the outer face of top wall 11 is a guide stem 13 formed integrally, as by molding, with launching base 8 and having a cross section less than the inside cross section or diameter of piston S but being substantially of the same extent. Encircling disposed about guide stem 13 is an elongated compression spring 14, one end of which bears against end wall 11. Spring 14, when unstressed, extends a substantial distance beyond the free end of guide stem 13. The diameter of spring 14 is substantially equivalent, or slightly less than, the inside diameter of piston 5.

In operation, the user, by gripping projectile l on

extensions

7,7, will cause the free end of spring 14 to be received within piston 5 and will thereupon direct projectile 1 toward launching base 8, causing stressing or compression of spring 14. As such action continues, the free end portion of projectile 1 will receive sidewall 9 of launching base 8 which is of slightly less cross section than the inside cross section or diameter of projectile 1. However, the diameter of flange 12 is slightly greater than the inside cross section or diameter of projectile 1 so that as the latter is forced thereby a slight deformation will be effected within the sidewall 2 of projectile l, as may best be seen in FIG. 5. The movement of projectile 1 onto launching base 8 is terminated upon abutment of the free end of guide stem 13 against end wall 6 of piston 5, at which juncture spring 14 will be fully compressed (see FIG. 5) and projectile 1 will be in such relation to launching base 8 as to cause toy A to be in loaded state (see FIGS. 4 and 5). At this point, the user will withdraw manual contact from toy A, relieving spring 14 from any countervailing manually applied pressure against the normal bias thereof. The movement of spring 14 toward an unstressed condition will be resisted by the friction developed between flange 12 and the engaged portion of projectile 1. However, such friction is not adequate: to balance or fully resist the releasing force of spring 14 so that projectile 1 will slowly move relative to launching base 8 until its free end margin will travel past flange 12 thereby liberating projectile 1 from the erstwhile impeding friction and subject same to the full releasing force of spring 14. By such releasing action projectile 1 will be propelled for relatively extensive travel in a missile or rocket simulating manner from said base 8 as suggested in FIG. 1.

It is to be especially noted that the distance between the free end of piston 5 and the free end margin 4 of projectile l is so determined as to control the relative: travel of projectile 1 along sidewall 9 of launching base 8 so that after projectile 1 has cleared said base 8, sufficient releasing force will be available within spring 14 to effect the necessary propulsion. It is also to be especially observed that the aforesaid distance between the free end of piston S and the open end 4 of projectile 1 together with the relative location of flange 12 on launching base 8 are such that a sufficient time interval is pro vided before projectile l loses contact with base 8 so as to allow the user to remove to a convenient point of observation before projectile l is launched.

In view of the foregoing it is indeed obvious that toy A lends itself to presentation in myriad attractive manners so that pro jectile 1 could take on the nature of any device, object, or character as might be desired.

As exemplary thereof is the toy indicated A in FIG. 6 which comprehends a projectile element 21 and a launching base which is the same as base 8 above described, and will hence bear the same reference numerals for sake of convenience.

Said base 8 thus incorporates a sidewall 9, with a continuous, relatively shallow flange l2 proximate its upper end; a top wall 11 from the center of the outer face of which projects a guide stem 13 about which is eneirclingly disposed an elongated compression spring 14.

Projectile 21 is unitarily formed, as of molded plastic or the like, and incorporates an upper body portion 22 which is exteriorly designed as to present the face of a child or other character. Depending from said body 22 is a skirt 23 having an inside diameter substantially equivalent to the outside diameter of sidewall 9 so that when projectile 21 is disposed upon base 8 a friction producing relationship will develop between the inner face of skirt 23 and flange 12 for the same purpose as with toy A hereinabove described. Body 22 is provided with an axial bore 24 which, at its lower end, opens in a lower end wall 25, said latter being continuous with the inner face of skirt 23. Lower end wall 25 radially outwardly of bore 24 slopes downwardly and outwardly, as at 26, with the diameter of the lower limit of said slope having a diameter substantially equal to that of top wall 11 of base 8. Formed for extension into bore 24 is a plurality of spaced-apart ribs 27 which substantially intermediate their length are cut back to define a downwardly presented shoulder 28', said shoulders 28 coacting to present a bearing surface for the upper end of spring 14. The upper portions of said ribs 27 are circumferentially spaced so as to allow movement therebetween of the upper end of stem 13.

With reference to FIG. 7, it will be seen that projectile 21 may be disposed in loaded condition upon base 8 in a manner corresponding to that in toy A above described. However, it will be seen thatthe abutment of the upper edge portion of top wall 11 of base 8 against the outer limit of the slope 26 of lower end wall 25, as indicated at 29, will determine the extent of compression of spring 14, as well as the overlapping extension of skirt 23 about sidewall 9 of base 8. Shoulders 28 thus provide a surface against which spring 14 may be compressed and with stem 13 being freely extensible within the portion of bore 24 thereabove. Thus, projectile 21 will eventually be forcibly ejected from base 8 as the release of spring 14 frees skirt 23 from deforming, friction-producing engagement with flange 12. Thus toy A demonstrates the versatility of the present invention and the ready adaptation thereof to preselected designs.
