- Referring initially to
FIGS. 1-7 , a rotatingplayground element 10 comprises ahollow member 12 mounted on asupport member 14. Thehollow member 12 is illustratively shown to be a sphere or ball, but could be any desired three dimensional shape. For example, thehollow member 12 could be a polyhedron (such as a pyramid or a platonic solid, e.g., a tetrahedron, a cube, an octahedron, a dodecahedron, or an icosahedron). Alternatively, the member could be oval or egg shaped. Thehollow member 12 has a plurality ofopenings 16 which are shown to be circular, but could be any desired shaped, to admit access to the interior of thehollow member 12. Further, although shown as a closed member with openings, thehollow member 12 could be opened at its top, and therefore could define an upwardly opening basket or bowl, for example. As long as children can access the interior of such baskets or bowls, such hollow members may not need theopenings 16. Thehollow member 12 has a dimension (e.g., diameter) sufficiently large to allow at least one child to sit in the hollow member. Similarly, at least one of theopenings 16 are sufficiently large to allow a child to climb through the opening to enter, or gain access to the interior of, the hollow member. Thehollow member 12, if spherical, can, for example, have a diameter of 3′ (about 100 cm), and theopenings 16, if circular, can have a diameter of about 2′ (about 60 cm). - The
hollow member 12 is fixed to amounting plate 18, which in turn is operatively connected to thesupport member 14. Thehollow member 12 can be fixed to themounting plate 18 in any desired manner, including bolting, welding, interlocking elements, or combinations thereof. - The
support member 14 comprises alower post 20, a majority of which is below ground level G. A pair ofrods 22 extends through thelower post 20 near a lower end of the post. Therods 22 are spaced from each other axially along thepost 20. As can be appreciated, therods 22 will extend into the ground surrounding thelower post 20 to help prevent thelower post 20 from rotating relative to the ground. Although tworods 22 are shown, only one rod could be used, or three or more rods could be used. Additionally, the rods could be replaced with paddles which would have generally vertically extending surfaces. Such paddles would also be effective in preventing rotation of the support post relative to the ground. Thelower post 20 defines a first axis A1, which is shown to be generally vertical. Alower axle 24 extends upwardly from the top of thelower post 20. Thelower post 20 is shown to be hollow, at least at an upper end thereof, and thelower axle 24 can comprise, or extend from, aninner post 26 which fixedly mounted within the hollow upper end of thelower post 20 and is sufficiently long to extend above the upper end of thelower support post 20. Thelower axle 24 is parallel to (and preferably co-axial with) the axis A1 defined by thelower support post 20. As best seen inFIG. 10 , thelower axle 24 has a lower, generally cylindrical, surface 24 a, a central taperedsurface 24 b, and an upper, generally cylindrical,surface 24 c. A pin 24 d extends from the end of theaxle 24. - A
central support member 29 comprising aspacer tube 50, alower bearing assembly 30 and anupper bearing assembly 60 is mounted on top of thesupport post 20. Thelower bearing assembly 30 is positioned on top of thelower axle 24. The lower bearing assembly comprisesbody 31 having a bottom mounting plate 32 with a truncatedconical portion 34 extending upwardly from the plate. The conical portion is smaller in diameter than, and concentric with, the mounting plate 32. The bearingassembly body 31 defines a hollow area having an inner surface. The body inner surface defines lower and upper outer races 36 a,b which are aligned with the lower and upper generally cylindrical surfaces 24 a,c of theaxle 24, respectively. Corresponding lower and upper bearing cones 38 a,b are journaled about the lower and upper generally cylindrical surfaces 24 a,c of thelower axle 24 and in alignment with the outer races 36 a,b. Lastly, a series of lower and upper bearings 40 a,b (such as cylindrical or tapered roller bearings) are located between the cones 38 a,b and the outer races 36 a,b. The bearings 40 a,b are held in position relative to each other by respective upper and lower bearing cages. Thus, thelower bearing assembly 30, and in particular, thebody 31, can rotate relative to thelower axle 24 about the axis A1. - A
closure 42 is positioned on top of the bearingbody 31. Theclosure 42 defines an opening sized and shaped to grippingly fit over the pin 24 d. A rod 44 extends radially into theclosure 42 and through the pin 24 d to fix the closure to the axle pin 24 d. Theclosure 42 includes a stem portion 42 a which is received in a countersunk recess in the upper surface of the bearingassembly body 31. The bearingassembly 30 is sealed to retain grease within the bearing assembly. A grease port 46 is provided to introduce grease into the bearing assembly should it become necessary to replace grease that has degraded or otherwise leaked from the bearing assembly. - The
spacer tube 50 comprises upper and lower flanges 52 a,b and is mounted by means of its lower flange 52 a to the mounting plate 32 of thelower bearing assembly 30. Thespacer tube 50 surrounds, and extends beyond, the truncatedconical portion 34 of thelower bearing assembly 30. Because thespacer tube 50 is mounted to the bearingassembly body 31, the spacer tube will rotate about the axis A1 relative to thelower support tube 20. Thespacer tube 50 is canted relative to the lower support tube, and defines an axis A2 which defines an angle alpha of about 5-10° relative to the axis A1 of thelower support tube 20. Thus, while the lower end of thespacer tube 50 is concentric (and co-axial) with thelower support tube 20, the upper end of the spacer tube is not. Hence, as the lower end ofspacer tube 50 rotates about the axis A1, the center of upper end of the spacer tube will orbit around the axis A1. Additionally, as seen inFIG. 9 , the upper flange 52 b of thespacer tube 50 is canted relative to the lower flange 52 a of thespacer tube 50, and thus, the flanges lie in planes that are not parallel to each other. The flanges 52 a,b define an angle α relative to each other, of between about 5° and about 15°. The upper flange 52 b need not be perpendicular to the axis A2. - The
upper bearing assembly 60 is mounted by way of itsflange 60 a to the upper flange 52 b of thespacer tube 50. Theupper bearing assembly 60 is identical to thelower bearing assembly 30, and thus need not be described herein. However, it will be seen that theupper bearing assembly 60 is inverted or upside down relative to thelower bearing assembly 30. Because the spacer top flange 52 b is canted relative to the spacer bottom flange 52 a, the upper bearing rotates about an axis A3 that is canted relative to the axis A1, and is offset from (or angled relative to) the axis A1 by about 5-15°. - The
upper bearing assembly 60 receives (or is journaled about) anupper axle 62. Theupper axle 62 is identical to thelower axle 24. As with theaxle 24, theupper axle 62 includes apost 64. Thepost 64 is received in anupper stand tube 66, such that the upper stand tube and theaxle 62 are rotationally fixed relative to each other. The mountingplate 18 to which thehollow member 12 is mounted is secured to the upper end of theupper stand tube 66. As noted, the rotating portion of the upper bearing assembly rotates relative to thespacer tube 50 about an axis A3. Thus, theupper stand tube 64, and hence thehollow member 12, will rotate about the axis A3. - The
hollow element 12 is supported by thelower tube 20, thecentral support member 29 and theupper stand tube 64, and these components, in combination comprise thesupport 14. Thehollow element 12 can rotate about the axis A3. Further, thehollow element 12 can orbit about the axis A1. This orbital motion would be in a plane that is generally perpendicular to the axis A1. As can be appreciated, thehollow member 12 can be rotated without orbiting, or can orbit without rotating. However, it is anticipated that children will most enjoy orbiting the hollow member about the axis A1 while rotating the hollow member about the axis A3. - As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. For example, the axis A2 of the
spacer tube 50 could be co-linear (i.e., parallel to) the axis A1 of the lower support tube. However, the flanges 52 a and 52 b of the spacer tube would still be canted relative to each other, such that the axis A3 of theupper support tube 66 is angled relative to the axis A1 of thelower support tube 20. Theplayground element 10 is shown and described with the axle posts 26 and 64 extending up from thelower support tube 20 and extending down from theupper stand tube 66, respectively, and thus the mounting flanges of the bearing assemblies are fixed to thespacer tube 50. However, this could be inverted, whereby the axle posts (and hence the axles) extend from opposite ends of the spacer tube, and the bearing assembly flanges could be secured to thelower support tube 20 and theupper stand tube 66. These examples are merely illustrative.
