The present invention relates to a merry-go-round for use on playgrounds, and more particularly to an elevated device which provides at least one, and preferably a plurality of hand holds disposed about a central support by which users can grab a hand hold and utilize their momentum to rotate them about the center support in one of various embodiments.
In the playground equipment business, there is always a perceived need for more fun to be had on the playground. The applicant recognizes this need for fun and endeavors to provide new products for playground use. Monkey bars provide a hand over hand lateral movement type play for users. Horizontally fixably supported bars provide a location for children to swing about such as to skin the cat or otherwise swing and play thereon.
Traditional merry-go-rounds provide a structure onto which children or even adults can push the merry-go-round around a center support connected to the ground and then place their feet on a platform to go round and round the center support. While various forms of merry-go-rounds have been developed for use for standing and/or sitting thereon, the applicant is unaware of an attempt at making a merry-go-round type structure onto which users can hang with their hands therefrom and be supported off the ground without contacting the ground. U.S. Pat. No. 4,286,781 shows a typical merry-go-round structure as has been available for many years. U.S. Pat. No. 4,982,949 shows a sitting merry-go-round arrangement.
Accordingly, an improved merry-go-round type play device is believed to be an advantageous addition to a playground.
It is a present object of the present invention to provide an improved merry-go-round type device for a playground.
It is another object of the present invention to provide a rotating structure having hand holds by which at least one user can grab and swing about the center support.
It is still another object of the present invention to provide an elevated merry-go-round having a plurality of hand holds which allow users to radially rotate about the center support while suspended by their hands.
It is another object of the present invention of at least some embodiments of the present invention to provide a center support having hand holds angled at a tilt relative to the center support whereby a specific hand hold passes through multiple elevations during a revolution about the center support.
In the presently preferred embodiment, a merry-go-round of the present invention provides a center support which connects to a frame a distance above the ground. More preferably, the center support elevates the frame a sufficient distance so that hand holds connected to the frame are at least a sufficient distance so that the feet and/or knees of a user do not touch the ground as they rotate about the center support. In some embodiments, the center support may be tilted where it connects to the frame and in other embodiments the center support portion may be supported in a pole like fashion perpendicular to the ground where it connects to the hand holds.
In some embodiments, a double ring type structure may be employed wherein a top ring is utilized to provide additional strength and support to the frame (and possibly additional hand holds) while in other embodiments such additional strength and/or hand holds may not be necessary or desired. By tilting the hand holds somewhat relative to a horizontal plane to the ground (such as perpendicular to a vertically extending pole, the applicant has found an embodiment which adds an additional type of fun).
The particular features and advantages of the invention as well as other objects will become apparent from the following description taken in connection with the accompanying drawings in which:
Connected to the hub extension 14 is a hub 18 which is illustrated connected to arms 20,22,24,26 at exterior surface 36 or otherwise hub 18. Gussets 28,30,32,34 are useful to assist in strengthening the structure and are illustrated connected to the exterior surface 36 of the gusset 18. A first end 38 of gusset 34 is illustrated connected to the exterior surface 36 of hub 18 while the upper surface 40 of gusset 34 is illustrated connected to arm 26. In the embodiment illustrated, the arms 26 extend from a hub connection point 42 downwardly to a first elevation change 44 in the preferred embodiment. In other embodiments, the arms 20,22,24,26 could drop less, drop none or even elevate hand hold assembly 46 at at least some portion of a revolution as will be described in further detail below.
Arms 20,22,24,26 are preferably downwardly directed and/or curved with a curve of the upper portion 40 of gusset 34 and others corresponding to the inner curve 48 of arms 20,22,24,26 as illustrated.
Internal to hub 18 are preferably one or more bearings. In the preferred embodiment two bearings are pressed fit into the hub 18 on the hub extension 14. In the preferred embodiment, arms 20,22,24,26 connect to a first member 50 which in some embodiments may provide a hand hold locations. In the preferred embodiment, spacers 52 separate first member from hand hold member 54 which provides a plurality of hand holds which can be seen in
Although center support 12 and post 16 are shown extending from the ground 56 upwardly, in alternative embodiments, it may be supported from above as would be understood by those of ordinary skill in the art. In
In practice, the upper elevation 60 and lower elevation 62 are assisted in being created as a result of the length 64 as shown in
When providing a sufficient change in upper and lower elevations 60,62, the applicant has discovered that a user such as child 58 may pump their body inwardly and outwardly at appropriate times during revolution about the center support 12 so that they may maintain the motion about the center support 12 by themselves. This is somewhat like “pumping” a swing to maintain its motion by one's self.
While the embodiment of
Although only one child 58 is shown playing in the embodiment of
In
Various elevations 60,62 and others can be selected based on the anticipated heights of children 58 and/or adults which play with the merry-go-round 10,65 and/or 88. An unobstructed zone 55 is located between the hand hold members 54,68,92 and the playing surface 56 as shown in
Numerous alterations of the structure herein disclosed will suggest themselves to those skilled in the art. However, it is to be understood that the present disclosure relates to the preferred embodiment of the invention which is for purposes of illustration only and not to be construed as a limitation of the invention. All such modifications which do not depart from the spirit of the invention are intended to be included within the scope of the appended claims.
