DETAILED DESCRIPTION

The following description is merely exemplary in nature and is in no way intended to limit the present teachings, application, or uses. Throughout this specification, like reference numerals will be used to refer to like elements.

Referring to FIG. 1, the present disclosure provides a rotating exercise device 10 that is structured and operable to make exercise more enjoyable and play-like by rotating about a vertical axis as a user performs one or more particular physical activities to operate one or more assemblies of the rotating exercise device 10.

Generally, the rotating exercise device 10 includes a seat 14 rotatably mounted to a pedestal 18 via a gear box 22 such that as a user, sitting on the seat 14, performs one or more particular physical activities, the seat controllably rotates about a substantially vertical longitudinal axis X of the pedestal 18. More particularly, the seat 14 is fixedly mounted to the gear box 22, which in turn is rotatably mounted to pedestal 18. The gear box 22, shown in FIG. 1 having a portion of a housing 26 removed, includes a plurality of interoperable gears 30. At least one of the gears 30 is controllably rotatable by the one or more particular physical activities performed by the user to thereby impart rotation of the other gear(s) 30 and cause rotation of the seat 14 about the X axis.

For example, in various embodiments, the gear box 22 includes worm gear 30A fixedly mounted to a stationary, i.e., non-rotatable, pedestal shaft 34 extending from a neck 36 of the pedestal 18. The pedestal neck 36 is rotatably mounted to a base 38 of the gear box 22 via a bottom bearing fixture 42, such that the gear box 22 and seat 14 are rotatably supported on the pedestal 18. Additionally, the pedestal shaft 34 terminates within a top bearing fixture 46 fixedly mounted to a top plate 50 of the gear box 22 to provide axial stability to the gear box 22 and seat 14 as the gear box 22 and seat 14 rotate about the X axis.

In such embodiments, the gear box 22 further includes a worm drive gear 30B fixedly mounted to a rotatable drive shaft 54 and cooperatively engaged with the worm gear 30A. The drive shaft 54 extends through, and is rotatably mounted within opposing gear box sides 58 via respective opposing side bearing assemblies 62. For ease and clarity of understanding, various gear box sides, including one of the opposing sides 58 and the corresponding side bearing assembly 62, have been removed from FIG. 1. However, one skilled in the art would readily and easily understand the structure and operation of the gear box 22 based on FIG. 1 and the disclosure provided herein. As described further below, the drive shaft 54 is driven, i.e., rotated about an axis Y, via a user operable drive mechanism (UODM) 66. The UODM 66 is illustrated with dashed lines to indicate that the UODM 66 can be any user operable mechanism suitable to rotate, i.e., drive, the drive shaft 54 and worm drive gear 30B fixedly mounted thereto.

Via control and operation of the user, the UODM 66 imparts rotational force on the drive shaft 54 to turn, or rotate, the worm drive gear 30B about the Y axis. Rotation of the worm drive gear 30B, in turn, imparts rotational force on the worm gear 30A. However, as described above, the worm gear 30A is fixedly mounted to the stationary pedestal shaft 34 that is fixedly mounted to the pedestal neck 36. Furthermore, the pedestal 18 is fixedly mounted to any suitable stationary base (not shown) such as the floor of a building, the surface of a play ground, a stationary base platform, etc. Thus, the pedestal 18, the respective pedestal neck and shaft 36 and 34, and the worm gear 30A are substantially stationary. That is, they do not rotate. Therefore, rotational force imparted on the worm gear 30A by the worm drive gear 30B causes the gear box base 38, top plate 50, sides 58 and housing 26 to rotate about the X axis as a result of the user operating the UODM 66. Moreover, as described above, the seat 14 is fixedly mounted to the gear box top plate 50 such that the seat 14 rotates about the X axis along with the gear box base 38, top plate 50, sides 58 and housing 26.

More particularly, in various implementations, the user operates the UODM 66 while sitting on the seat 14. Thus, as the user operates the UODM 66 the user rotates about the X axis making operation of the UODM 66 fun and enjoyable.

Although the various embodiments described herein, describe the gears 30 as including a worm gear 30A and a worm drive gear 30B, it is envisioned that the gears 30 can include any other type of gear set that will impart rotation force on the stationary pedestal shaft 34 to cause the gear box 22, seat 14 and user to rotate about the X axis as a result of the user operating the UODM 66, and remain within the scope of the present disclosure. For example, in various embodiments, the gears 30 can include two or more cooperative bevel gears that impart rotation force to cause the gear box 22, seat 14 and user to rotate about the X axis as a result of the user operating the UODM 66.

Referring now to FIGS. 2, 3 and 4, in various embodiments, the UODM 66 can comprise a pair of opposing foot pedal and crank assemblies 66A. More particularly, each foot pedal and crank assembly 66A includes a crank arm 70 and a foot pedal 74. A proximal end of each crank arm 70 is fixedly mounted to a respective one of the opposing ends of the drive shaft 54 that extend outside of the gear box housing 26. Particularly, the opposing crank arms 70 extend radially in opposite directions from the respective opposing drive shaft ends. Each foot pedal 74 is mounted to a distal end of a respective one of the crank arms 70 to extend orthogonally away from the gear box 22 and is structured and operable to be rotatable about a respective center axis Z. Accordingly, as shown in FIGS. 2, 3 and 4, the foot pedal and crank assemblies 66A, in combination with the seat 14, provide bicycle-like arrangement, whereby the user can sit on the seat 14 and turn the foot pedal and crank assemblies 66A with his/her feet in a bike pedaling manner.

In various embodiments, the seat 14 includes at least one handle 78 for the user to hold while sitting on the seat 14. The at least one seat handle can be any device, structure or apparatus structured and located such that the user can easily, conveniently, and comfortably hold the handle(s) to steady himself/herself on the seat 14 and safely operate the rotating exercise device 10. For example, as exemplarily illustrated in FIG. 3, in various implementations the seat handle(s) 78 can be a set of bicycle-like handlebars, as exemplarily shown in FIG. 3 that are appropriately attached to the rotating exercise device 10, e.g., attached to the seat 14, the gear box 22 or a seat post 82, to rotate about the X axis along with the seat 14 and gear box 22, as described herein. Or, as exemplarily illustrated in FIG. 2, the seat handle(s) 78 can comprise a handle 78 formed in a portion of a saddle-like seat 14 such that the user can sit in the seat 14 with the handle 78 located in front of the user where the user can easily grasp the handle 78 as he/she operates, i.e., pedals or turns, the foot pedal and crank assemblies 66A with his/her feet. Or, alternatively, in various embodiments, the seat handle(s) 78 can be a set of side rails that are appropriately attached to the rotating exercise device 10, e.g., attached to the seat 14, the gear box 22 or a seat post 82, to rotate about the X axis along with the seat 14 and gear box 22.

Additionally, in various embodiments, the seat 14 can be mounted to the seat post 82 that is mounted to the gear box top plate 50 such that the seat 14 is positioned a particular distance above the gear box 22 and the foot pedal and crank assemblies 66A. Moreover, in various implementations, the seat post 82 can be structured and operable to be height adjustable such that the distance of the seat 14 above the gear box 22 can be adjusted to accommodate various users of different heights.

Referring now to FIGS. 3 and 4, as a user operates, i.e., pedals or turns, the foot pedal and crank assemblies 66A, the drive shaft 54 rotates in the direction in which the foot pedal and crank assemblies 66A are being turned. As a result, the worm drive gear 30B also turns in the direction in which the foot pedal and crank assemblies 66A are being turned. As described above, the worm drive gear 30B is cooperatively engaged with the worm gear 30A, which is fixedly mounted to the stationary pedestal shaft 34. Accordingly, rotation of the drive shaft 54 and worm drive gear 30B, resulting from the operation of the foot pedal and crank assemblies 66A by the user, will apply rotational force to the gear box 22 via the drive shaft 54 and side bearing assemblies 62. This rotational force will cause the gear box 22, the foot pedal and crank assemblies 66A and the seat 14 (and a user sitting in the seat 14) to rotate about the X axis making operation of the rotating exercise device 10, i.e., pedaling of the foot pedal and crank assemblies 66A, fun and enjoyable.

Referring now to FIG. 5, in various embodiments, the gear box 22 and foot pedal and crank assemblies 66A can be enclosed in a protective housing 86 and side shields 90 (only one of which is shown in FIG. 5). The protective housing 86 and side shields 90 protect the gear box 22 and the foot pedal and crank assemblies 66A from damage due to weather, environmental debris and physical abuse. The protective housing 86 and side shields 90 can also provide aesthetic character and design to the rotating exercise device 10.

Referring now to FIGS. 6, 7 and 8, in various embodiments, the UODM 66 can comprise a chest bar and crank assembly 66B. Generally, the chest bar and crank assembly 66B includes a chest bar subassembly 94 (FIG. 8) that is operatively coupled to a pair of drive shaft crank linkages 98 via a linking shaft 102. The linking shaft 102 is rotationally mounted within a pair of front bearing assemblies 110 that are mounted to a front plate 106 of the gear box 22. The chest bar subassembly 94 includes a lever arm 114, a head unit 118 pivotally coupled to a distal end of the lever arm 114 and a shaft mounting bracket 122 coupled to a proximal end of the lever arm 114. The mounting bracket 122 is fixedly coupled to a center portion of the linking shaft 102, between the front bearing assemblies 110, and each of the drive shaft crank linkages 98 are fixedly mounted to a respective one of opposing ends of the linking shaft 102 that extend past the respective front bearing assemblies 110. Via rotation of the linking shaft 102, the chest bar subassembly 94 is movable between a Forward position (as shown in FIG. 6) and a Home position (as shown in FIG. 9), wherein the head unit 118 is located substantially above the gear box front plate 106.

The mounting bracket 122 additionally includes a range limiting tongue 126 extending therefrom that contacts a stop 130 to limit the range of motion between the Home and Forward positions of the chest bar subassembly 94. In various embodiments, the stop 130 can be a block mounted to the gear box front plate 106.

Each drive shaft crank linkage 98 generally includes a plurality of rotationally connected link arms that connect the linking shaft 102 with the drive shaft 54 such that movement of the chest bar subassembly 94 between the Home and the Forward positions incrementally rotates the drive shaft 54 and the worm drive gear 30B mounted thereon. For example, in various embodiments, each of the side bearing assemblies 62 comprises a one-way bearing assembly 62A that is structured and operable to only allow the drive shaft 54 to rotate in one direction. Additionally, in such exemplary embodiments, each drive shaft crank linkage 98 includes a proximal link arm 134, and intermediate link arm 138 and a distal link arm 142. The proximal link arm 134 is fixedly connected at a first end to the respective end of the linking shaft 102 and rotationally connected at a second end to a first end of the intermediate link arm 138. Similarly, a second end of the intermediate link arm 138 is rotationally connected to a first end of the distal link arm 142. In various implementations, a second end of the distal link arm 142 includes a clutch mechanism 146 that fits onto, and is structured to selectively engage, the respective end of the drive shaft 54.

Accordingly, movement of the chest bar subassembly 94 between the Home and Forward positions reciprocally moves that second end of each proximal link arm 134 in an arc. The movement of the proximal linking arm second ends is transferred to the first end of the distal linking arms 142 such that movement of the chest bar subassembly 94 between the Home and the Forward positions causes the clutch mechanisms 146 to rotate about the Y axis (shown FIG. 7). More specifically, in various embodiments, as the chest bar subassembly 94 is moved from the Home position to the Forward position, each clutch mechanism 146 engages the drive shaft 54, thereby rotating the drive shaft 54 and worm drive gear 30B in a desired direction, e.g., a clockwise direction. Then, as the chest bar subassembly 94 is moved from the Forward position to the Home position, each clutch mechanism 146 substantially disengages the drive shaft 54, and the one-way bearing assemblies 62A prevents the drive shaft 54 from rotating in a direction opposite the desired direction, e.g., a counter-clockwise direction. Thus, repeated movement of the chest bar subassembly 94 between the Home and the Forward positions incrementally advances, or rotates, the drive shaft 54 and worm drive gear 30B in the desired direction, e.g., the clockwise direction.

It should be understood that although repeated movement of the chest bar subassembly 94 between the Home and the Forward positions has been exemplarily described as incrementally advancing the drive shaft 54 and worm drive gear 30B in a clockwise direction, the clutch mechanisms 146 and one-way bearing assemblies 62A could be structured and operable such that movement of the chest bar subassembly 94 incrementally advances the drive shaft 54 and worm drive gear 30B in the counter-clockwise direction. Additionally, although operation of the chest bar subassembly 94 and the crank linkage 98 has been described above such that movement of the chest bar subassembly 94 from the Home position to the Forward position causes incremental rotation of the drive shaft 54 and worm drive gear 30B, it should be understood that the chest bar subassembly 94 and the crank linkage 98 can be structured and operable so that movement of the chest bar subassembly 94 from the Forward position to the Home position causes the incremental rotation of the drive shaft 54 and worm drive gear 30B and remains within the scope of the present disclosure.

As described above, the worm drive gear 30B is cooperatively engaged with the worm gear 30A, which is fixedly mounted to the stationary pedestal shaft 34. Accordingly, the incremental rotation of the drive shaft 54 and worm drive gear 30B, resulting from the operation chest bar subassembly 94 by the user, will apply incremental rotational force to the gear box 22 via the drive shaft 54 and one-way side bearing assemblies 62A. This rotational force will cause the gear box 22, the chest bar subassembly 94 and the seat 14 to incrementally rotate (e.g., rotate in 30° increments) about the X axis making operation of the rotating exercise device 10, i.e., moving the chest bar subassembly 94 between the Home and the Forward position, fun and enjoyable.

Referring now to FIGS. 6, 7, 8 and 9, in various embodiments, the gear box 22 and crank linkages 98 can be enclosed in a protective housing 150 that protects the gear box 22 and crank case linkage 98 from damage due to weather, environmental debris and physical abuse. The protective housing 150 can also provide aesthetic character and design to the rotating exercise device 10. Additionally, in various embodiments, the seat 14 can be connected to the gear box top plate 50 (as shown in FIG. 1) and/or connected to a top portion of the protective housing 150.

Furthermore, the seat 14 is mounted such that a user sitting in an upright position in the seat 14, i.e., with his/her torso generally in an upright orientation, will face the chest bar subassembly 94 and be able to comfortably touch his/her chest to the chest bar subassembly head 118. The user can also wrap his/her arms around the chest bar subassembly head 118 to hold the head 118 firmly against his/her chest. Subsequently, using his/her abdominal muscles, the user can bend forward, while remaining seated in seat 14, to move the chest bar subassembly 94 from the Home position to the Forward position, thereby incrementally advancing the drive shaft 54, as described above. The user can then move to the upright sitting position to move the chest bar subassembly 94 back to the Home position. Thereafter, the user can repetitively move the chest bar subassembly 94 between the Home position and the Forward position, using his/her abdominal muscles, i.e., by performing abdominal crunches, to incrementally rotate the chest bar subassembly 94 and the seat 14 (and the user sitting in the seat 14) about the X axis, thereby making operation of the rotating exercise device 10, i.e., performing abdominal crunches, fun and enjoyable. The chest bar subassembly 94 can also be provided with a spring mechanism which biases the chest bar subassembly 94 to the Home position. Such a spring mechanism will provide resistance which must be overcome by the user to move the chest bar subassembly 94 to the forward position and will also aid in returning the chest bar subassembly 94 to the Home position. Such a spring could, for example, extend between the tongue 126 and an appropriate place on the housing front plate 106 or bottom.

The description herein is merely exemplary in nature and, thus, variations that do not depart from the gist of that which is described are intended to be within the scope of the teachings. Such variations are not to be regarded as a departure from the spirit and scope of the teachings.
