## Background
FIELD OF THE INVENTION
The present invention relates generally to the field of exercise and recreational devices. More particularly, the present invention relates to an elevated rail system for use with a manually operated carriage suspended therefrom.
BACKGROUND OF THE PRIOR ART
The prior art provides a number of stationary cardiovascular exercise machines. Such machines include treadmills, stationary bicycles, elliptical machines, rowing machines and the like. These devices are commonly found at health clubs and in private residences.
A problem with such prior art machines is that they can become monotonous to use. The user is stuck in a single position for the entire duration of an exercise session.
U.S. Pat. No. 4,928,601 attempts to address this problem by providing a monorail system having a track on a top side thereof for receiving and guiding the tires of a traditional bicycle on a top side of the monorail system track. A user may then ride the bicycle around on the monorail track. A problem with this prior art system is that the bicycles must be fitted with a special apparatus in order to avoid physical contact with other bicycles. Additionally, bicycles must ride in-line with each other, preventing one user from passing another or achieving a speed faster than a bicycle positioned in front of the user.
A further problem with the above system is that it is limited to the use of bicycles at the exclusion of other types of cardiovascular exercise machines.
It would, therefore, be advantageous to provide a system that overcomes these and additional shortcomings of the prior art.
SUMMARY OF THE INVENTION
The present invention provides a recreational apparatus and travel apparatus that includes an elevated rail system and a carrier suspended therefrom.
The carrier includes a frame and drive assembly such as a pedal assembly such that, for example, a rider may comfortably ride in the carrier and access the drive assembly, such as with his or her legs in the case of a peddle assembly. The drive assembly may be coupled, such as via a chain, to a wheel assembly or other such motive assembly, which causes the carrier to advance along the elevated rail system when the drive assembly is operated by the rider.
The frame is slidably suspended from the elevated rail system by a coupling assembly. The coupling assembly may incorporate one or more sets of rollers for slidably contacting the frame to the rail.
The coupling assembly is connected to the frame of the carrier such that the motive assembly or wheel assembly provides the driving force for advancing the coupling assembly along an elongate pathway defined by the rail.
The elevated rail system may incorporate a plurality of interlinked pathways wherein one or many carriers may advance along any number of such pathways. For example, the rail system may include any number of diverters having a single pathway that leads to multiple pathways, wherein any of such pathways may be selectively taken by a carrier.
The carrier may further include any number of performance features including but not limited to a hand brake for slowing the drive wheel assembly, a hand throttle for adjusting the frictional force between the drive wheel and rail, and an adjustable guide for preselecting one of a plurality of paths along the rail system.
A variety of different carrier arrangements and configurations may be utilized in accordance with the present invention, including but not limited to a bicycle configuration, an elliptical machine configuration, a rowing machine configuration and a treadmill machine configuration or other such exercise equipment configurations.
These and various other features and advantages of the present invention shall be described in more detail in the following sections.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 illustrates an elevated rail system 10 defining an elongate pathway about which a carrier 12 is able to travel. The carrier 12 is suspended from the elevated rail system 10 by a coupling assembly 14 configured to slidably engage the rail 16 of the elevated rail system 10. The carrier 12 is advanced along the rail 16 by engaging a pedal assembly 18 that is operably coupled to a drive wheel assembly 20.
In the present embodiment, the carrier 12 includes a frame 22 for supporting a seat assembly 24 and pedal assembly 18 such that the pedal assembly 18 is accessible therefrom. As shown, the seat assembly 24 includes a seat portion 26, a back support 28 and one or more handles 30 on opposing sides of the seat assembly 24.
The pedal assembly 18 of the present embodiment is a crank 32 and gear system 34 as is common in the art and is rotatable about an axis 36 supported by a lower portion of the frame 22. A chain 38 couples the pedal assembly 18 to the wheel assembly 20.
The wheel assembly 20 of the present embodiment includes a wheel 40 rotatable by a gear system 42 when the pedal assembly 18 is engaged. It is contemplated that the gear system 42 may include shiftable gears such that the chain 38 may be selectively positioned on any one of a plurality of parallel gears.
An upper section of the frame 22 provides an axis 44 for the wheel assembly 20 and further provides one or more connecting members 46, 47 for selectively securing the frame 22 of the carrier 12 to the coupling assembly 14.
FIGS. 2A and 2B illustrate a more detailed view of the coupling assembly 14 of the present embodiment. A first and second set of rollers 48, 49 are spaced from each other about a coupling frame 50. The rollers 48, 49 are configured to be received within a channel 52 of the elevated rail system 10 such that the coupling frame 50 is suspended therefrom. The rollers 48, 49 thus are slidably received within the channel 52 of the elevated rail system 10. In the present embodiment each set of rollers 48, 49 includes a first roller 54 received on a first lip 56 of the channel 52 and a second roller 58 received on a second lip 60 of the channel 52 and to rotate about an axis 64 such that a periphery of the roller 54, 58 contacts the lip 56, 60 of the channel 52 respectively.
A limit roller 62 or fin extends from a fixed section of the axis 64 such that the limit roller 62 extends within the channel 52 of the rail 16. The limit roller 62 prevents the coupling assembly 14 from swinging from side to side with respect to the elongate pathway defined by the rail 16. It is further contemplated that the elongate rail system 10 may include a plurality of intersecting pathways. In such case, the fin 62 may be selectively positioned to guide the coupling assembly 14 into a predetermined one of said plurality of pathways.
The rollers 48, 49 are connected to the coupling frame 50 by one or more guide rollers 66 that extend about a generally vertical axis through the channel to connect to the coupling frame 50. The coupling frame 50 of the present embodiment further provides a fixed axis 68 for a translation wheel 70. The translation wheel 70 rotates about the axis 68 so as to simultaneously contact the bottom surface of the rail 16 and the top surface of the drive wheel 40 of the carrier 12. In operation, the rotation of the drive wheel 40 will cause the translation wheel 70 to rotate in the opposite direction and thus drive the carrier 12 along the elongate pathway in accordance with the rotation of the translation wheel 70.
It is contemplated that the chain 38 extending between the pedal assembly 18 and drive wheel assembly 20 may be configured such that the translation wheel 70 may be eliminated and the drive wheel 40 makes direct contact with the rail 16 wherein a forward pedal motion will result in a forward motion of the carrier 12 along the rail 16.
Returning now to the present embodiment, the connecting members 46, 47 of the carrier are each connected to the coupling frame 50 via a corresponding tension member 72, 73. The tension member 72, 73 of the present embodiment incorporates a threaded inner sleeve 74 and corresponding outer connecting sleeve 76. The outer sleeve 76 may be adjusted with respect to the inner sleeve 74 to selectively increase or decrease the frictional contact between the drive wheel 40 and the translation wheel 70.
It is contemplated that the tension member 72, 73 could alternatively be used to selectively increase or decrease direct functional contact between the drive wheel assembly 20 and the rail 16 in an embodiment of the present invention wherein the translation wheel 70 has been eliminated.
In this or other embodiments described herein, it is contemplated that a number of controls and coupling systems may be accessible and/or operable from the handle 30 of the seat assembly 24. For example, a hand brake may be coupled to brake pads positioned about the drive wheel 40; a guide may be coupled to the fin 62 for selectively choosing a pathway; a throttle may be coupled to the tension member(s) 72, 73 to selectively adjust the tension between the drive wheel 40 and the rail 16; and additional such controls and coupling systems may be incorporated and operably accessible from the seat assembly 24.
