DETONATING TOY PROJEOTILE Filed May 9, 1963 C Him- Ila 3 "b F 1' E1 4 INVENTOR flarnoawaosmon Ewmm 3,225,490 DETONATING TOY PROJECTILE Raymond G. Ostrom, Minneapolis, Minn., assignor to Nordic Enterprises, Inc, Minneapolis, Minn., a corporation of Minnesota Filed May 9, 1963, Ser. No. 279,244 8 Claims. (Cl. 46200) This invention relates generally to a detonating toy and more specifically to a paper cap detonating toy modeled to closely resemble a hand grenade.

In manufacturing childrens toys, it is often desirable to closely simulate the appearance and operation of an actual item so that childrens games may be more realistic in nature. It is, therefore, an object of this invention to provide a paper cap detonating toy in which the outer body is constructed to closely resemble a hand grenade as used by the Armed Forces and wherein a time delay mechanism delays the detonation of the paper cap for a period of time simulating the action of an authentic grenade.

It is an object of this invention to provide a hand grenade wherein a friction-producing member is provided to delay the detonation of a paper cap for a specific amount of time after a pin initiating the detonating action is pulled from the grenade.

It is a further specific object of this invention to provide a detonating hand grenade having adjustable friction means such that the delay time of detonating the paper cap may be adjusted for any period of time.

It is another object of this invention to provide a hand grenade wherein a paper cap may be mounted on a detonating surface directly underlying a detonating hammer means such that a paper cap will be exploded upon contact therebetween, producing noise and smoke to simulate the action of an authentic hand grenade.

It is a further object of my invention to provide a childrens toy wherein the moving parts will not be easily removed and therefore not easily lost.

It is a further object of this invention to provide a detonating toy for use by children wherein a paper cap is completely contained within a hollow body and the detonating action is designed to prevent detonation of said cap unless said body is in an assembled condition thus providing a safe toy in that children will not be harmed by the exploding cap.

These and other objects and advantages of this invention will more fully appear from the following description made in connection with the accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the several views, and in which:

FIG. 1 is a plan view of the invention;

FIG. 2 is a side elevational view thereof;

FIG. 3 is a transverse sectional view taken substantially along the line 3-3 of FIG. 2; and

FIG. 4 is a vertical section taken substantially along line 44 of FIG. 1 and drawn to an enlarged scale.

In accordance with the accompanying drawings, an exploding hand grenade includes a main body element 11 having a hollow portion 12 extending longitudinally therein, a fixed detonating plate member 13 on one end thereof and a movable detonating hammer 14 to forcibly contact the detonating plate member 13 as to strike a paper cap C or other explosive element placed thereon.

More specifically, the detonating hammer 14 comprises a guide shaft 15 with a substantially enlarged end portion 16 including the detonating surface 17 arranged generally normal to said shaft 15. The guide shaft extends upward through one end 18 of the hollow chamber 12 and through a tubular guiding member 19 tightly received into a passage 25 through the main body 11. In the form 3,225,490 Patented Dec. 28, 1965 shown, the tubular guide 19 is firmly pressed into the passage 25 to an abutting shoulder 20. The inner end 22 of the guide 19 converges to a small guide opening 23 for the guide shaft 15 and allows the same to move longitudinally therethrough. A spring element 21 is further interposed between said shoulder 20 and the enlarged end 16 of the detonating hammer 14 and serves to urge the detonating hammer member 14 forcibly downward to contact the explosive C arranged on the detonating plate 13. A friction-producing spring member 24 is arranged on the other end of the guide shaft 15 and, in the form shown, comprises a small semi-rigid wire member forming a loop with the ends 24a securely attached to said guide shaft 15. The dimension across said loop portion of the spring member 24 is greater than the diameter of a constricted portion 25a of passage 25 as to be in contact therewith when moving longitudinally therethrough thus retarding the motion of said detonating hammer 14 as it moves through said reduced portion 25a. A sleeve member 27 is arranged in the outermost portion of the passage 25 and has a small diametrical opening 27a therethrough such that a pin 28 may pass therethrough and further pass through the loop portion 24 of the friction-producing spring member 24, thus locking the detonating hammer 14 in a cocked position. Upon withdrawal of said pin 28 as by pulling the ring member 28a attached thereto, the spring 21 forcibly urges the detonating hammer downwardly as shown by the dotted portion in FIG. 4. The friction spring member 24 retards the motion of said vdetonating hammer as it passes through the constricted portion 25a of the passage 25 producing a delaying action. The detonating plate 13 comprises a generally flat portion having a locating extension 13a therebehind to be received in the passage 26 through the main body 11 in alignment with the guide opening 23. A plurality of openings 29 extend through the periphery of the main body 11 and into the hollow chamber 12 for the release of noise and smoke therefrom upon detonation of a paper cap C placed on the detonat ing plate 13.

In the form shown, the main body is divided into two portions 11a and 11b held together by a pair of expansible pin members 33 associating with openings 33a afiording ease of assembly and disassembly and further maintaining alignment between the acting members. Although pins 33 have been provided to secure the two portions 11a, 11b together, it may be easily seen that any connecting device, such as a hinge, which would enable the user to gain access to the. hollow chamber 12 for reloading of the detonating toy would be appropriate.

In operation of the detonating toy, the portions 11a, 11b are separated and a paper cap or other similar toy explosive is placed on the detonating plate 13. The de tonating hammer 14 is forced upward against the spring member 21 to align the loop of the friction-producing spring member 24 with the diametric opening 27a and the locking pin 28 is placed therethrough. The two portions of the main body 11a, 11b are then re-aligned and pushed together. Upon pulling of the ring 28a and pin member 28 to unlock the detonating hammer 14, the hammer 14 is urged downward by the spring 21. This downward motion is retarded by the friction-producing spring member 24 passing through the constricted portion 25a of the passage 25 as by contacting the sides of said passage. This friction produces a delay in the downward progress of the hammer until said friction-producing portion 24 passes from the constricted passage 25a where its release allows the hammer 14 to be forcibly propelled downward into contact with the paper cap exploding the same causing smoke and noise to issue from the openings 29. It may be seen from the construction of the frictionproducing member 24 that the shape of said member may be altered to produce a loop of greater or less width resulting in either more or less friction as it passes through the constricted passage 25a thus producing a longer or shorter time delay from the time of pulling the pin 28 to detonation.

To change the shape of the friction member 24 the detonating hammer may be removed by pulling the detonating hammer 14 through the guide opening 23 and bending the friction member 24 to the desired shape. It is also possible to replace the spring member 21 with a more or less powerful spring producing a greater or less striking force.

It may be easily seen that applicant has produced a realistic toy hand grenade wherein a simple and unique method is used to produce a time delay action to more closely simulate a real grenade, and although the main body portion is described as resembling a hand gernade, it is obvious that the detonating mechanism may be used in toys of other shapes.

It will, of course, be understood that various changes may be made in the form, details, arrangements and proportion of the parts without departing from the scope of my invention, which generally stated, consists in the matter set forth in the appended claims.
