SKY-DIVER TOY WITH PACK AND PARACHUTE COMBINATION INVENTOR. Robert W. GordonlZI ATTORNEYS United States Patent 3,257,752 SKY-DIVER TOY WITH PACK AND PARACHUTE COMBINATION Robert W. Gordon III, 1 S. Albion St., Denver, Colo. Filed July 30, 1964, Ser. No. 386,269 Claims. (Cl. 46-86) a sky diving toy which is simple and durable in construction so as to operate efiiciently over long periods of usage.

Another object of my invention is to provide a durable and efficient timing mechanism which will consistently and accurately release the parachute at selected time intervals and is conveniently adjustable for various height projections.

Another object of my invention is to provide a sky diver toy in which the parachute pack is instantly unfastened and released at the end of a preselected time interval, thus assuring consistent operation of the parachute.

Further objects and advantages of my invention will become apparent as the following description proceeds, and the features of novelty which characterize my invention will be pointed out with particularity in the claims annexed to and forming a part of this specification.

For a better understanding of my invention reference may be had to the accompanying drawings in which:

FIG. 1 is a perspective view of the sky-diver toy of this invention showing the back pack in an enclosing position;

FIG. 2 is a side view of the toy shown in FIG. 1 in a descending position with the parachute opened;

FIG. 3 is an enlarged fragmentary rear elevation of the toy shown in FIG. 1 illustrating in detail the fastening arrangement for the back pack; and

FIG. 4 is an enlarged fragmentary front elevation of the toy shown in FIG. 1 illustrating in detail the motor and stop arrangement. 1

Referring to FIGS. 1-4 there is shown a sky-diver toy generally designated by numeral 3. This toy includes a head 4 mounted on a body or trunk portion 5. Arms 6 and legs 7 extend from the body and are preferably constructed of flexible wire mesh (FIG. 3) capable of being shaped in a curved manner and suitable for absorbing the impact with the ground resulting from the fall.

A harness 8 is fitted around body 5 with a simulated pack 10 attached thereto at the lower front portion of the body which is not operational. A back pack 11 is operational for enclosing and discharging the parachute and which is attached to harness 8 at the back of body 5.

Back pack 11 includes a back portion attached to harness 8 from which extend a top flap 12 and bottom flap 13 which extend downwardly and upwardly, respectively, over the folded parachute. Side flaps 14 and 15 extend from the back portion and overlap the top and bottom flaps with side flap 14 overlapping side flap 15, thereby fully enclosing parachute 16 when in a folded position. One end of parachute 16 is preferably attached to harness 3 Where it extends over the shoulder portion of the body (FIG. 2). Alternately, direct attachment of the parachute to the body could be made.

For holding the pack portions in the enclosing position there is provided a fastening arrangement on the side flaps. Overlapping side flap 14 has three openings spaced vertically at upper, central and lower positions near its outer edge for receiving loops or

eyelets

21, 22 and 23, respectively, which are attached at spaced upper, central, and lower positions near the outer edge of overlapped side fiap 15.

Pins

25, 26 and 27 extend through

loops

21, 22 and 23, respectively, for holding the overlapping sides in position, thereby completing the fastening arrangement for'holding the pack 11 in an enclosing position.

This fastening arrangement is released by simultaneously pulling

pins

25, 26 and 27 from

loops

21, 22 and 23, respectively, in a manner more fully described hereinafter.

A cord 29 extends through eye portions of

pins

25, 26 and 27, respectively, and is attached thereon at equally spaced distances along the cord. This cord extends over one shoulder of the body 5 and attaches at its other end to a key 30 extending from the front central portion of body 5.

The body 5 has a hollow interior which houses a driving mechanism or motor 31 preferably of a spring-wound type having a rotary shaft 32 extending to the exterior of the body on which key' 30 is fastened. A gear 33 is mounted on the shaft within the body. A switch or brake arm 34 is pivot-ally mounted within the body for engagement with gear 33 to alternately lock and release for rotation of motor 31. One end of brake arm 34 has a sharp edge for engagement with the teeth of gear 33 and the opposite end extends through a slot in a side of body 5 for vertical movement by the operator. An upward force on the brake arm portion extending through the slot releases engagement with the gear and a downward force engages the gear to stop the motor rotation.

Flexible or

elastic bands

35, 36 and 37 arev disposed in spaced relation at upper, central and lower positions of pack 11, extend around its back portion, and attach by a hook and eye arrangement near the outer edges of

side flaps

14, 15. Attachment of the bands on the side flaps is in line with and inwardly of the flap edges from a fastening loop and eye combination described above. When the pack is in an enclosing

position bands

35, 36 and 37 are under tension so that upon release of the pack fasteners the side portions will be retracted to facilitate discharge of the folded parachute enclosed therein.

Attachment of the bands to the edges of the side flaps includes

hooks

38, 39 on the ends of band 35; hooks 41, 42 on the ends of band 36; and

hooks

44, 45 on the ends of band 37. At the upper position of pack 11 eyelet 48 attaches to side flap 15 opposite from eyelet 49 attached to side flap 14 with hook 38. in eyelet 48 and hook 39 in eyelet 49. Centrally of pack 11 eyelet 51 attaches to side flap 15 opposite from eyelet 52 attached to side flap 14 with hook 41 in eyelet 51 and hook 42 in eyelet 52. At the lower position of pack 11 eyelet 54 attaches to side flap 15 opposite from eyelet 55 attached to side flap 14 with hook 44 in eyelet 54 and hook 45 in eyelet 55.

In operation motor 31 is wound by the operator and brake arm 34 set in a downward position to lock the rotation of motor 31. The parachute 16 is folded and enclosed by the flaps of pack 11.

Pins

25, 26 and 27 are pushed through

loops

21, 22 and 23, respectively (FIG. 3), thereby enclosing the parachute in a fastened arrangement.

Immediately prior to projecting the toy into the air brake arm 34. is pushed upwardly, allowing key 30 to rotate with shaft 32, thereby winding cord 29 around the shaft and key and pulling the pins from their respective loops when the toy reaches a position at or near its highest point.

After the pins are pulled,

side flaps

14 and 15 are retracted by the

elastic bands

35, 36 and 37 to facilitate discharge of the parachute 16 so that the toy will descend to the ground under the suspension of the parachute.

The time interval for releasing the pack fastening may be varied to accommodate different heights of projection by varying the length of

pins

25, 26 and 27 or the degree of penetration of the pins in the eyelets.

The various components of the toy may be made of a variety of materials suitable for withstanding the shock encountered. Various rotary drive mechanisms capable of a brake lock and release are obviously suitable.

Although I have illustrated a specific embodiment of my invention, various modifications will occur to those skilled in the art. Therefore, I do not desire my invention be limited to the specific details illustrated and described and I intend by the appended claims to cover all modifications which fall within the spirit and scope of my invention.
