Description
- This application claims 35 USC 119 priority from U.S. Provisional Application Ser. No. 62/448,274 filed Jan. 19, 2017, which is incorporated by reference herein.
- The present invention relates to devices used in relation to the training of dance skills, and more specifically to a turning board constructed and arranged for use in training dance balance and pivoting skills.
- Dancers often perform exercises for improving their skills, and for performing routine dance moves more effectively. One such dance move is the pivot or pirouette, performed as the dancer spins about a vertical axis. Maintaining balance during this move is important for transitioning to and from the pirouette.
- Conventional training devices are available for enhancing dancer skills by providing a base that is placed on the floor, and having a rotating platform pivoting on the base. The dancer practices pirouetting while standing on the rotating platform. However, the conventional training devices are limited in their utility for training other dance moves and skills.
- Thus, there is a need for an improved dance training board which addresses the need of dancers to practice a variety of dance moves.
- The above-listed needs are met or exceeded by the present dance balance/turning board, which features a base with a rotating platform, as well as a bowl-shaped hemispheroidal balance surface selectively mounted below the base. With the balance surface detached from the base, a user places the base upon the floor, and can practice pirouetting or pivoting by spinning on the rotating platform. When balance training is desired, the user attaches the hemispheroidal balance surface to the base in a manner that prevents the rotating platform from rotating.
- In the preferred embodiment, the hemispheroidal surface is provided with a locking mechanism including at least one pin that projects through a designated opening in the base, and also engages openings in the rotating platform. The engagement of the at least one pin with the corresponding openings in the platform prevents rotation of the rotating platform relative to the base. In addition, engagement of the at least one pin with the base secures the balance surface to the base.
- Thus, with the hemispheroidal balance surface attached to the base of the present board, the user is able to practice exercises that enhance balance skills. The balance surface is placed on the floor, and the user places at least one foot on an upper surface of the base, including but not limited to the rotating platform, which is now locked from rotating.
- More specifically, the present invention provides a dance balance/turning board, including a base having an upper surface and an opposite lower surface; a turntable bearing having a lower flange mounted to the upper surface, and an upper flange; a rotating platform secured to the upper flange for axial rotation relative to the base; and a hemispheroidal balance surface mountable to the lower surface and including a locking mechanism engageable with said rotating platform, so that upon the mounting, the rotating platform is disabled from rotating.

FIGS. 1-5 , the present dance balance/turning board is generally designated 10, and provides a user the ability to train for dancing using several different balancing and rotating techniques. More specifically, theboard 10 includes abase 12, preferably disk-shaped, however other shapes are contemplated, and having anupper surface 14 and an oppositelower surface 16, a plurality ofpin bores 18 and a plurality ofmounting bores 20. In the preferred embodiment, thebase 12 is circular and has a diameter of in the approximate range of 15-30 inches, however other diameters are contemplated depending on the application. In the preferred embodiment, there are fourpin bores 18 and fourmounting bores 20. Preferably, thepin bores 18 are arranged on thebase 12 in a larger diameter than themounting bores 20, however that relationship may vary to suit the application. Also, it is contemplated that the number and arrangement of thebores - A turntable bearing, also known as a Lazy Susan Bearing is generally designated 22 and is provided with a
lower flange 24 having a plurality ofmounting apertures 26. Thelower flange 24 is mounted to theupper surface 14 of thebase 12 with conventional fasteners (not shown) such as threaded screws, using themounting bores 20. However, the use of chemical adhesives in replacement of, or as supplement to, threaded fasteners is contemplated. In one embodiment, thebase 12 is provided with a recess 25 (FIG. 1 , shown in phantom) dimensioned for accommodating thelower flange 24 so that the lower flange is flush with the upper surface. Anupper flange 28 is provided withupper mounting apertures 30 and, as is known in the art, a plurality of ball bearings (not shown) is captured between the upper andlower flanges Such turntable bearings 22 are known in the art, and a suitable example has a 300 lb. load maximum, ¼ inch ball bearings and a 4-inch square dimension on the upper andlower flanges - A
rotating platform 32 having a diameter that is smaller than thebase 12 is secured to theupper flange 28 using fasteners (not shown) such as threaded screws. In the preferred embodiment, therotating platform 32 has a diameter of 10 inches, however variations are contemplated depending on the application. In general, therotating platform 32 has a smaller area or diameter than thebase 12. A similar recess 33 (FIG. 1 , shown in phantom) is contemplated in an underside of therotating platform 32 as described above for therecess 25, which accommodates the upper bearingflange 28 so that it is flush with the underside. Once secured to thebearing 22, the rotatingplatform 32 rotates axially relative to thebase 12. As is the case with thebase 12, therotating platform 32 is provided withupper pin bores 34 disposed in a larger diameter thanupper mounting apertures 36, (shown hidden) to define a rough circle, however the actual disposition of thepin bores 34 may vary to suit the application. It should be noted that therotating platform 32 is rotatable so that theupper pin bores 34 are in registry with thepin bores 18. - Referring now to
FIG. 1 , therotating platform 32, the turntable bearing 22 and the base are preferably assembled as follows. As seen inFIG. 1 , thelower flange 24 is rotated approximately 90° relative to theupper flange 28, and before assembly to therotating platform 32, fasteners for securing thelower flange 24 to the base are inserted through theapertures 26 in the flange so that heads of the fasteners are caught in the aperture. Heads of the fasteners are selected to that they do not interfere with the rotation of theupper flange 28 relative to thelower flange 24. Next, therotating platform 32 is secured to theupper flange 28, so that the fasteners passing through theupper mounting apertures 30 are mounted from the upper flange into an underside of the rotating platform. Preferably, the fasteners are not long enough to project through the rotating platform to anupper surface 38. Finally, the fasteners for thelower flange 24 project through thebase 12 to thelower surface 16, where they are secured, for example by nuts. It is also contemplated to use rivets for securing thelower flange 24 to thebase 12. - The
present board 10 also includes ahemispheroidal balance surface 40 which is constructed and arranged to be mountable to thelower surface 16 of thebase 12 so that upon mounting, the turntable bearing 22 is disabled from rotating and therotating platform 32 is fixed relative to the base. Included on thehemispheroidal balance surface 40 is abowl portion 42 with anouter surface 44 and aperipheral edge 46. A feature of thepresent balance board 10 is a locking mechanism that prevents therotating platform 32 from rotating relative to thebase 12 when thehemispheroidal balance surface 40 is in place. In the preferred embodiment, the locking mechanism includes thepin bores pins 48 that project from theedge 46 away from thebowl portion 42. In the preferred embodiment, thepins 48 are integrally formed with the bowl portion. However, it is also contemplated that supplementalloose pins 50 are provided (FIG. 2 ). It is also contemplated that thebowl portion 42 is either solid, partially solid or hollow, and is made of a variety of materials that provide sufficient strength for supporting the weight of a user balancing on thebase 12. In the preferred embodiment, thebase 12, the rotatingplatform 32, thebalance surface 40 and thepins 50 are all made of durable plastic, however other materials are contemplated. Also, thebalance surface 40 can be molded of plastic having a variety of hardness values (Shore A Hardness or Durometer) to provide users with varying levels of difficulty. - Referring now to
FIG. 4A , an alternate configuration for thehemispheroidal balance surface 40 is depicted as 40A, and has abowl portion 42A. It will be seen that the radius of curvature of abottom portion 51 of theouter surface 44A is different from, and preferably larger than, that shown inFIGS. 1-4 and 5 , and as such presents a “flatter” curve or shape that contacts the floor or other substrate. In other words, the radius of curvature of thebottom portion 51 is distinct from a radius of curvature of theouter surface bottom portion 51 are shown in dashed lines inFIG. 4A . The shape of thebottom surface 51 inFIG. 4A is contemplated as providing distinct balancing characteristics as compared with the shape of thebowl portion 42 inFIGS. 1-4 and 5 . It will be appreciated, that the shape of thebalance surface - The
balance surface 40 is attached to thebase 12 and to therotating platform 32 by inserting thepins 48 through the pin bores 18 in the base as well as through the aligned upper pin bores 34 in the rotating platform. In the preferred embodiment, thepins tip 54, and as thebalance surface 40 is pressed towards thelower surface 16, thepins 48 tightly engage the pin bores 18, and 32 to secure the assembly together via a friction fit. As such, upon engagement of thepins 48 with the upper pin bores 32, the rotatingplatform 32 is prevented from rotating relative to thebase 12, and the pins and bores form a locking mechanism as well as securing thebalance surface 40 to the base. It will be appreciated that a thickness or diameter of thepins present board 10. It will also be appreciated that other locking mechanisms are contemplated for preventing rotation of therotating platform 32 upon attachment of thehemispheroidal balance surface 40 to thebase 12 and engagement between thesurface 40 and the rotating platform. - Referring now to
FIG. 4 , it will be seen that in the preferred embodiment, thepins 48 extend through the upper pin bores 34. When the user desires to detach thebalance surface 40 from thebase 12, the board is inverted, and the user merely presses the base against the floor or other substrate. This action will force thetips 54 back into the rotatingplatform 32 and will thus facilitate release and disengagement of thebalance surface 40 from thebase 12. - Referring now to
FIGS. 4 and 5 , upon engagement with thebase 12, thetips 54 of thepins 48 are visible through the upper pin bores. However, it is preferred that thepins 48 are dimensioned so that upon engagement of the pins in the upper pin bores 34 in the rotatingplatform 32, thetips 54 do not protrude past theupper surface 38. In one embodiment, thebalance surface 40 is provided in a color distinct from the rotatingplatform 32 so that thepin tips 54 are more easily visually distinguished, and the user can see that thebalance surface 40 is in place. Upon assembly of theboard 10 as seen inFIG. 5 , the user is able to practice balance exercises without the potential of the rotating platform moving relative to thebase 12. - Another feature of the
present board 10 is that a layer of resilient,high friction surface 56 such as rubber or the like (shown fragmentarily inFIGS. 3 and 4 ) is optionally provided on the rotatingplatform 32 for enhanced grip and traction by the user's feet. It will be understood that the configuration of anysuch layer 56 would need to be coordinated with the length of thepins 48 as described above. Also, in one embodiment, thebase 12 is provided with at least onehandle 58 which is dimensioned for being grasped by the user for easy carrying. It is also contemplated that multiple handles orcutouts 58 are provided (FIG. 5 ) so that the user can grip the base 12 with both hands for performing exercises, such as planking moves or push-ups, with thebalance surface 40 attached to the base. The number, size and placement of thehandles 58 may vary to suit the application. - Referring now to
FIG. 3 , still another optional feature of thepresent board 10 is the inclusion of at least one, and preferably a plurality of circumferentially spacedresilient feet 60 secured, as by adhesive or the like to thelower surface 16 of thebase 12. Inclusion of the feet will space the base 12 from the floor or other substrate, and will enhance friction or traction of the base relative to the floor. - Referring again to
FIG. 2 , another optional feature is to include a bubble orball level 62 mounted in an assignedsocket 64 in the upper surface. The placement of thelevel 62 on thebase 12 may vary to suit the situation. - Referring again to
FIG. 1 , it is also contemplated to mount awireless speaker 66 and associated circuitry 68 (both shown in phantom) into either the base 12 or thehemispheroidal portion 40. Upon installation, the user can use theboard 10, through thespeaker 66, to broadcast music sourced from a smartphone or other remote device, using an appropriate app as is well known in the art. Also as is well known in the art, thecircuitry 68 is powered by a rechargeable battery using a USB cable, or the like. - Referring now to
FIG. 6 , an alternate embodiment to the present board is generally designated 70. Components shared with theboard 10 are designated with identical reference numbers. A main difference between theboards 10 and 70 is that the latter features the rotatingplatform 32 recessed and rotatably mounted within acavity 72 in abase 74, which is contemplated as being thicker than the base 12 to maintain the required strength and to accommodate thebearing 22. Thus, upon assembly, theupper surface 38 of therotating platform 32 is generally flush with theupper surface 14 of thebase 74. - In use, when pirouette training is desired, the user places the
base rotating platform 32 for practicing spinning-related dance exercises or the like. When balance training is desired, the user installs thebalance surface 40 by engaging thepins 48 in the respective bores 18, 34. As described above, insertion of thepins 48 in thebores rotating platform 32. This arrangement permits the user to practice balancing exercises using theboard 10. Also, the user has the option of preventing rotation of therotating platform 32 relative to thebase 12 without using thebalance surface 40, by merely aligning the pin bores 18 and 34 and inserting the supplementalloose pins 50 in the same manner as thepins 48. Alternately, theloose pins 50 are optionally insertable from the rotatingplatform 32 so as to create a drag on the rotation of the platform relative to the base. In this manner, new users can create a limit of rotation rate of theplatform 32 as they learn the respective dance exercises. - While a particular embodiment of the present dance balance/turning board has been described herein, it will be appreciated by those skilled in the art that changes and modifications may be made thereto without departing from the invention in its broader aspects and as set forth in the following claims.
