10 Claims, 4 Drawing, Figures Germany 272/49 I 1 PLAYGROUNDAMUSEMENT DEVICE BACKGROUND OF THE INVENTION 1. Fieldof the Invention Playground amusement device.

2. Description of the Prior Art Children in seeking amusement endeavor to find a device in which the actuation thereof isaccomplished by the concurrent effort of two or more individuals.

, Merry-go-round devices that are actuated by the com bined effort of a number of children have proved to be quite popular, and rare at the present date the only amusement device known to the applicant that permits joint efforts on the part of a number of children to provide a ride.

A primary objectin devising the present invention is V to supply an amusement device that is actuated by a first child, for his amusement, and such actuation resulting in at least one second child being given a ride in a vertical circular path.

Another object of the invention is to supply a play-v ground amusement device that is safe, simple and easy to operate, can be fabricated from standard, commercially available material, is durable, and one that requires a minimum of maintenance attention.

SUMMARY OF THE INVENTION A rotatable assembly that includes a horizontally disposable shell, a tubular sleeve concentrically disposed therein, and rigid means extending outwardly from the sleeve to support the shell therefrom. The sleeve is rotatably supported on at least one horizontal shaft that.

is held in a fixed position above the playground surface by at least one upwardly extending support. Each support preferably has the lower end portion thereof embedded in a body of concrete that is buried in the ground.

The rigid means that form a part of the rotatable assembly serves a second function of pivotally supporting at least one second seat. When a first child is within the shell and walks or runs relative to an upwardly inclined portion of the interior surface thereof, the assembly rotates and the second seat supportedchild is caused to move in a vertical circular path.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a first perspective view of the device;

FIG. 2 is a second perspective view of the device;

FIG. 3 is a combined vertical cross sectional and side elevational view of the device; and

FIG. 4 is a fragmentary exploded perspective view of the device illustrating the manner in which the seat is pivotally supported therefrom.

DESCRIPTION OF THE PREFERRED EMBODIMENT The playground amusement device A as may be seen in FIGS. 1 and 2 includes a rotatable assembly B of such size as to permit a first child C to walk or run within the interior thereof. The assembly B pivotally supports a seat D on which a second child E may be situated. When the first child C walks or runs relative to an upwardly inclined portion of the interior surface of the assembly B, the assembly rotates the seat D and second child E is moved through a circular vertically extending path.

The rotatable assembly B as may be seen in FIGS. I and 2 includes a rigid cylindrical shell 10 that rotates about a horizontal axis 12. The shell 10 is preferably about seven feet in internal diameter. The shell 10 preferably has first and second laterally spaced, circular reinforcing ribs 14 and I6 welded or otherwise secured to the interior surface thereof.

An elongate tubular sleeve 18 is concentrically disposed relative to shell 10 and extends longitudinally along axis 12. Sleeve 18 has a number of circumferentially spaced rigid spokes 20, preferably formed from channel iron radiating outwardly therefrom, with the outer ends of the spokes being secured to the first rib 14 by welding or the like. The first open end 10a of shell 10 is closed by a heavy wire mesh sheet 22 that is rigidly secured to the spokes 20 by conventional means. The wire mesh sheet 22 has numerous openings 22a therein to permit the first childl C and second child E to see one another as the device is operated.

The sleeve 18 as best seen in FIG. 3 has the interior end portions thereof rotatably supported on two shafts 24, that are held at a desired elevated position above the playground surface 30 by two supports 28. Of course, if desired, the two shafts 24 could extend the entire length of the sleeve 18, and in effect, merge into one another and be a single shaft. The shafts 24 preferably have flanged annulus shaped members 26 mounted therein that extend over the exterior end portions of the sleeve 18 to minimize the possibility of dirt and foreign material entering the confines of the sleeve 18. Such foreign material when it would so enter the sleeve would be lodged between the interior surface portions thereof and the shafts 24 and would appreciably increase the'frictional resistance of the sleeve 18 turning on the shafts 24 and slowing down the rate of rotation of the assembly B when actuated by the first child C.

If desired, the annulus shaped members 26 may have oil or grease fittings mounted thereon (not shown) to lubricate the end portions of sleeve 18 that rotate on the shafts 24. The height of the supports 28 is such that the lower portion of the shell 10 is disposed between 6 inches and a foot above the playground surface 30. The lower ends of the supports 28 as shown in FIG. 3 are embedded in bodies of concrete 32 that are buried below the ground surface. 7

The interior surface of the shell 10 as shown in FIG. ll has a number of circumferentially spaced laterally extending cleats or foot bars 32 secured thereto. The foot bars 32 permit the first child C to obtain better traction as he walks or runs relative to an upwardly inclined portion of the interior surface of shell 10. One of the members 28 has a bar 34 rigidly secured thereto and the bar 34 extending into the shell 10 through a second open end 3412 thereof. A portion of the bar 34 defining a handle 34a that may be grasped. by the first child C when he is walking or running relative to the interior surface of the shell 10.

One of the spokes 20 as best seen in FIGS. 3 and 4 has a stub shaft 36 extending outwardly therefrom on which a tapped bore 38 is defined. The stub shaft 36 pivotally supports a tubular member 360 that has an L- shaped support 40 extending downwardly therefrom and on which the seat D is mounted. An interior disposed side wall 44 of seat D has an opening (not shown) thereon through which a bolt 46 may be extended to engage the tapped bore 38.

The bolt 46 has a head 48 thereon of sufficient size as to prevent the tubular member 28 being inadvertently disposed from the stub shaft 36 when the bolt is in engagement with the tapped bore 38. The tubular member 38 as may be seen in FIG. 3 is disposed a substantial distance above the center of gravity 50 of the seat D and second child E when disposed thereon, and as a result there is no tendency for the seat to pivot to an inverted position as the seat moves through a vertical circular path.

The seat D is so positioned relative to the sleeve 18 that neither the seat D nor the second child E when situated thereon will be brought into pressure contact with the sleeve 18 as the device A operates by energy from the first child C. The force exerted by the first child C when walking or running relative to the shell is disposed outwardly from the sleeve 18 a greater distance than the center of gravity 50, and as a result this differential in turning radius will assure rotation of the assembly B if the first child C and second child E are substantially equal in weight.

The use and operation of the invention is quite simple. The first child C enters the shell 10 through the second open end 34b thereof and assumes the position illustrated in FIG. 2. As the first child C walks or runs relative to an upwardly inclined portion of the interior surface of the shell 10, and in contact with the cleats 32, the shell 10 tends to rotate in a counterclockwise direction as illustrated by arrows in FIG. 1 with the second child E disposed on the seat D being treated to a ride through a circular path.

The first child C and second child E may alternately change positions to more fully enjoy operation of the playground device A. The use and operation of the invention has been described previously in detail. It will be apparent that the spokes 20 and wire mesh 22 could be replaced by a rigid circular plate if desired and the invention would continue to be operable as previously described.
