Definitions
- the present invention relates generally to athletic training equipment and, more particularly, to such equipment for training athletes in gymnastics, acrobatics, and like athletic movements. More specifically, the present invention relates to a spotting apparatus utilizing a transportable frame to support a spotting seat cage in a manner providing a user with one or multiple axes of rotation within the support frame.
- An athletic trainer comprising: a support frame having a pair of lateral supports attached to one another in a spaced-apart manner, each of said pair of lateral supports having a base member and a lateral frame extending therefrom, said lateral frame comprising a pair of members attached to one another at a first end in a manner defining a pivotal support surface and each pair of members separately attached at a respective second end to said base member; and a spotting apparatus having a front brace and a rear brace, said spotting apparatus received in a caged manner by each of said pivotal support surfaces, whereby said pivotal support surfaces of said pair of lateral supports cooperatively define a first axis of rotation, about which said caged spotting apparatus may selectively rotate.
- an athlete in the athletic trainer is supported within the spotting apparatus by the support frame, which in turn is supported—not suspended.

Abstract
An athletic trainer has a spotting apparatus received by a support frame. A pair of connected, spaced-apart lateral supports define the support frame and provide a pair of pivotal support surfaces that together provide a first axis of rotation, about which the spotting apparatus may selectively rotate. The spotting apparatus may consist of connected front and back braces with a ledge seat attached to the back brace for support and comfort. Alternatively, the spotting apparatus may be a unitary, substantially circular brace having an internal bearing raceway and attached support webbing that permit rotation about a second axis.
Description
- This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/804,265, filed Jun. 8, 2006.
- The present invention relates generally to athletic training equipment and, more particularly, to such equipment for training athletes in gymnastics, acrobatics, and like athletic movements. More specifically, the present invention relates to a spotting apparatus utilizing a transportable frame to support a spotting seat cage in a manner providing a user with one or multiple axes of rotation within the support frame.
- The worldwide popularity of Cirque du Soleil productions harkens back to the days of the big top and the “Greatest Show on Earth.” Acrobatic performers demonstrating advanced gymnastic procedures that communicate seemingly effortless artistry. Reality, of course, is quite different—the performers are highly skilled athletes that must continually train body and mind to accomplish the techniques required for a night's performance.
- Many of the audience favorites involve suspended artists performing maneuvers in an apparently weightless condition. While wires and harnesses are not new technology, these newer shows have placed requirements on this older technology that were never intended. In most cases, the performer pays the price, in terms of greater stresses placed on his/her body.
- In some cases, these stresses require the performer to limit his/her time in the harness or risk career-ending injuries. A need exists for a redesigned support harness that enables a performer to practice the performance maneuvers and perform them in an environment that is more physically comfortable without sacrificing safety and support.
- An athletic trainer comprising: a support frame having a pair of lateral supports attached to one another in a spaced-apart manner, each of said pair of lateral supports having a base member and a lateral frame extending therefrom, said lateral frame comprising a pair of members attached to one another at a first end in a manner defining a pivotal support surface and each pair of members separately attached at a respective second end to said base member; and a spotting apparatus having a front brace and a rear brace, said spotting apparatus received in a caged manner by each of said pivotal support surfaces, whereby said pivotal support surfaces of said pair of lateral supports cooperatively define a first axis of rotation, about which said caged spotting apparatus may selectively rotate.
- According to aspects of embodiments of the present invention, an athlete in the athletic trainer is supported within the spotting apparatus by the support frame, which in turn is supported—not suspended. The support frame thus eliminates the requirement for rigging that is typically required to create this aerial state. The support frame also eliminates the requirement for a high-ceiling location, which is a requirement for rigging installations.
- Another aspect in accordance with embodiments of the present invention is the stabilization of the center of gravity. Once installed within the spotting apparatus, as supported by the support frame, the athlete is airborne, and the center of gravity becomes the point of rotation. Such rotational motion is initiated by muscle contraction by the athlete, and not by a motor or by a random momentum. The athlete has full control of the direction and speed of rotation.
- Another aspect in accordance with embodiments of the present invention relates to comfort and ease of adjustment. The spotting apparatus forms a rigid structure surrounding the waist of the athlete, and acts as a safety cage—the body of the athlete is not compressed. The rigid ledge seat in the spotting apparatus supports the buttocks and can easily be adjusted in height to fit children as well as tall adults. The shoulder support straps secure the position of the athlete in the upside down position.
- A still further aspect in accordance with embodiments of the present invention is about the ease with which the athletic trainer can be installed and re-located. The structure is exceedingly light and can easily be re-located—even when fully assembled. The design of the support frame makes it easy to assemble and tear down for storage.
- These and various other advantages and features of the present invention are pointed out with particularity in the claims. Reference should also be had to the drawings which form a further part hereof, as well as to the accompanying descriptive matter in which are illustrated and described in various examples of with the invention.

FIG. 14 is a perspective view of a support frame and a spotting apparatus having a substantially circular brace. - Reference is now made to the drawings wherein like numerals refer to like parts throughout. In
FIG. 1 , aspotting apparatus 10 is shown supported by asupport frame 14. A pair ofsupport brackets 18 receive thespotting apparatus 10, which is attached thereto using a pair ofrotation brackets 22 to enable rotational movement of thespotting apparatus 10 relative to the pair ofsupport brackets 18. - A pair of
end supports 26 are located on each end of the pair ofsupport brackets 18. U-shaped in form, each of the pair of end supports 26 consist of a pair ofuprights 32 that are attached to one-another by abase connector 34. Each of the pair ofuprights 32 is attached to a separate one of the pair ofsupport brackets 18, with the resultant construction of thesupport frame 14 maintaining the latitudinal stability of thesupport brackets 18. A pair of telescopic adjustable bars 16 are attached towards the bottom of the U-shapedend support 26. - The
spotting apparatus 10 consists of arear brace 42 and afront brace 44, with the rear brace extending outwardly a sufficient distance to be received by therotation brackets 22, as is shown inFIG. 1 . Of course, thespotting apparatus 10 may be supported by other structures not shown in the Figures. For example, when used during a performance, the extending portions of therear brace 42 might be received by pillow blocks with hanging points, which would permit the use of thespotting apparatus 10 by “flying” artists (not shown in the Figures). - Returning once again to
FIG. 1 , asupport webbing 48 is attached to thespotting apparatus 10 to provide further restraint to a user (not shown inFIG. 1 ). Thesupport webbing 48 preferably consists of afront suspenders 52 that extends over a user and attaches to a pair ofsuspender attachments 54 that are placed upon thefront brace 44. In addition, a pair ofleg straps 56 are also provided, with each extending from between a user's legs, crossing a (separate) leg, to aseat strap attachment 58 located on therear brace 42. - A securement
pin 62 is used to lock thefront brace 44 to therear brace 42. As is best shown inFIG. 2 , thefront brace 44 is preferably adouble bar brace FIG. 2 ). Therear brace 42 is received between thedouble bars - It is also within the scope of the present invention to utilize a more permanent connection between the
front brace 44 and therear brace 42, such as replacing thesecurement pin 62 with one of thebrace fasteners 68. In such an instance, a user would be required to “slip in” to the unified brace structure, instead of being permitted to “walk in” as is the case with a pivotingfront brace 44 as shown inFIG. 3 . - When pivoting about a second point of attachment to the
rear brace 42, thefront brace 44 is able to swing sufficiently wide that a user can easily be positioned against therear brace 42. Once so positioned, thefront brace 44 again pivots to a closed position, where it is again (temporarily) attached to therear brace 42. - Referring once again to
FIG. 3 , aseat 72 is attached to therear brace 42 using avertical adjustment bar 76. The latter permits a user to adjust the height of the seat, and thereby adjust the center of gravity of the user to a vertical position that is substantially the same as the rear brace 42 (also the axis of rotation). - Referring now to
FIGS. 4 and 5 , thevertical adjustment bar 76 is provided with a plurality ofseat fasteners 78 that may be placed anywhere along a vertical array of openings (also seeFIG. 1 ), which together enable a user to set theseat 72 at an appropriate height over a wide variety of body heights and weights. - In
FIG. 6 anacrobat 82 has rotated to an upside-down position relative to thesupport frame 14, while being comfortably secured within the spottingapparatus 10. Continued rotation of theacrobat 82 relative to thesupport frame 14 returns theacrobat 82 to an up-right position. When properly adjusted, only minor shifts in body weight are required to obtain large rotational body movements of theacrobat 82. - The spotting
apparatus 10 and thesupport frame 14 of the present invention are both preferably fabricated out of a light-weight metal, such as the present choice of light-weight steel. Aluminum might also be appropriate, although there is a concern regarding its ability to fail by shattering. - In a presently preferred embodiment, the
support frame 14 includes the pair of adjustable telescopic bars 16 measuring 44 inches in length at the shortest to 68 inches at the longest (it is triangular in cross-section). The height adjustment of the frame is achieved by lengthening or shortening the telescopic bars 16. Ideally, theentire support frame 14 weighs no more than approximately 30 pounds, and can be collapsed without tools to fit within a carrier bag (not shown in the Figures). - The front and
rear braces - The cage, seat, and support webbing cooperative work together to restrain the artist in a manner that cannot be obtained by harnesses, which were forced to provide both support and restraint. As an example, when the artist rotates either forward or back, the only “restraint” felt is the front or back of the cage—unlike where harnesses are used, which also grip the artist's sides. The relatively greater freedom provided by the present invention permits the artist to make greater use of his/her muscles while placed in these unusual attitudes.
- The
rear brace 42, which also forms the rotational axis, measures 46 inches in length, and is uniformly curved, reaching a maximum deviation from linear of 4.5 inches at a location 23 inches from either end. Thefront brace 44 consists of a double-bar construction, each of 40 inches in length and uniformly curved, with a maximum deviation from linear of 7½ inches at a location 20 inches from either end. - The support webbing is preferably fabricated out of any of several types of synthetic fabric material, with conventionally adjustable COBRA® Buckles used as the fasteners to attach the webbing to the restraints. The
seat 72 is preferably fabricated out of a solid material, such as medium soft steel, having a semi-circular shape that measures 13 inches by 4 inches. The seat forms an “attachment” location for the artist to the cage, and is not required to be a full seat in terms of size—such would actually interfere with some maneuvers. The vertical adjustment bar measures 8 inches in length and can be fabricated out of very strong materials, such as high-strength steel and aluminum alloys. - In a presently preferred alternative embodiment, shown in
FIG. 8 , anathletic trainer 92 includes a double-bar spotting apparatus 96 that is positioned upon a pair of triangular lateral supports 98. A pair ofbase support connectors 102 attach together the pair of lateral supports 98, creating a supportingframe 104. Abase frame 106 of the supportingframe 104 includes the pair ofbase support connectors 102 and abase member 108 that forms the supporting member for each of the pair of lateral supports 98. Preferably, thebase member 108 consists of a pair of telescoping bars 108 a, 108 b. - A pair of
circular skid pads 114 are received by each of thebase support connectors 102 and provide both vertical and lateral support to theathletic trainer 92. Further stabilization is sometimes required, such as when the acrobat/user is performing dynamic or violent actions. In such cases thecircular skid pads 114 might be replaced by bolt-down attachments or guy-wire attachments (both not shown in the Figures) or, as is shown inFIG. 9 , asupplemental support brace 118. - The triangular lateral supports 98 include a
base member 102 and a pair ofupright members 122. InFIG. 10 the pair ofupright members 122 are attached to one another utilizing aconnector plate 126. A receivingslot 128 is formed in an upper portion of theconnector plate 126. A split-collar bearing 132 is positioned in the base of the receivingslot 128, and receives arotational axis shaft 136 that extends from the spottingapparatus 96. - The
rotational axis shaft 136 is provided an inscribedbearing surface 138 that is received by the split-collar bearing 132 to better maintain the lateral position of therotational axis shaft 136 relative to theconnector plate 126. Vertical restraint of therotational axis shaft 136 is provided by aslot cap connector 144 that is attached to theconnector plate 126 and extends across the receivingslot 128. Further restraint is provided by aterminal collar 148 that is attached adjacent an end of therotational axis shaft 136, as is depicted inFIG. 11 . -
FIG. 12 shows aledge seat 148 centrally located within a doublebar spotting apparatus 96. While it is contemplated that some padding will be included on the ledge seat 148 (not shown inFIG. 12 ), the seat is reduced in size to avoid interfering with certain types of movement by the athlete. Upperbody support webbing 152 and lowerbody support webbing 154 are attached to theledge seat 148. Such webbing may include the leg straps 56 as part of the lowerbody support webbing 154 and thesuspender attachments 54 as part of the upperbody support webbing 152. - The
ledge seat 148 is attached to theback brace 158, a double bar brace, similar to thefront brace 44. The presently preferred manner of attachment is best shown inFIG. 13 . A two-piece seat clamp 164 is attached to the front and back sides of theback brace 158 using a pair of threadedconnectors 166. By incorporating theledge seat 148 into this same connection, the same pair of threadedconnectors 166 also tightly holds theledge seat 148 against the two-piece seat clamp 164. -
FIG. 14 illustrates the use of the supportingframe 104 as a support base for a substantially circular, unitarybrace spotting apparatus 172—such as is presently offered for sale by Norbert's Athletic Products, Inc., under the product name “Rotator Twisting Belts” (see www.norberts.net). These circular braces typically have support webbing that is attached to support brackets extending from bearing raceways. As so supported, the webbing permits rotational movement about a second axis of rotation, with therotational axis shafts 136 providing rotational movement of the athlete about a first axis of rotation. - My invention has been disclosed in terms of a preferred embodiment thereof, which provides an athletic trainer having a support frame and spotting apparatus that is of great novelty and utility. Various changes, modifications, and alterations in the teachings of the present invention may be contemplated by those skilled in the art without departing from the intended spirit and scope thereof. It is intended that the present invention encompass such changes and modifications.
