BACKGROUND OF INVENTION

[0001] Mountaineering, also called Mountain climbing, is a popular sport with over 25 million people climbing regularly around the world. In many instances, the mountain being climbed has a height that requires the climber to be physically fit. The term “mountain fitness” has been defined as the ability to move efficiently and safely over mountainous terrain and uneven, rocky surfaces, and endure continuous uphill movement for the hours it will take to get to the top of the mountain. The term “mountain fitness” further includes the strength and stamina required to safely descent from the top of the mountain.

[0002] Various methods are known to acquire mountain fitness, including the non- limiting examples of personal trainers, rock wall trainers, running up and down stairs and the like. However, these conventional methods can be time-consuming, expensive and may not result with the desired results.

[0003] It would be advantageous if the action or movement of climbing or crawling up or down a mountain could be better simulated.

SUMMARY OF INVENTION

[0004] The present invention is directed toward an exercise machine and climbing simulator that enables its users to initiate the climbing or crawling motion whilst being rotated at different angles. This invention is a direct solution to the lack of mountain climbing simulation products on the market. It includes a rotatable framework and a plurality of foot spines and arm spines that are configured to support the feet and arms of a user. As the framework rotates 360 degrees, the user incurs strenuous physical activity in maintaining contact with the plurality of foot and hand spines. Each of the foot and hand spines is decoupled from each other, that is, each of the foot and hand spines is configured with independent rotational and lateral movement. By changing the angles of rotation and the positions of the foot and hand spines, gravity is applied in different ways and therefore different muscle groups of the user are targeted. Thus, this invention assists users in acquiring varying degrees of physical fitness and mountain climbing preparation.

[0023] Unless otherwise indicated, all numbers expressing quantities of dimensions such as length, width, height, and so forth as used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless otherwise indicated, the numerical properties set forth in the specification and claims are approximations that may vary depending on the desired properties sought to be obtained in embodiments of the exercise machine and climbing simulator. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the exercise machine and climbing simulator are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical values, however, inherently contain certain errors necessarily resulting from error found in their respective measurements.

[0024] The description and figures disclose an exercise machine and climbing simulator. The exercise machine and climbing simulator is configured to simulate the action or movement of crawling up a mountain and down a mountain and is further configured to instill a level of mountain fitness to a user.

[0025] Referring now to the drawings, there is illustrated in Fig. 1 an exercise machine and climbing simulator (hereafter “simulator”) generally at 10. The simulator 10 is configured to simulate the action or movement of crawling up or down a mountain and is further configured to instill a level of mountain fitness to a user. Generally, simulator 10 includes a rotatable framework 12 supported by a base assembly 14. The rotatable framework 12 is shown in a first rotational orientation. The rotatable framework 12 includes a plurality of foot spines 16a, 16b configured to support the feet of a user during rotation of the framework 12 and a plurality of hand spines 18a, 18b configured to support the hands of a user during rotation of the framework 12. As the framework 12 rotates, the user incurs exercise in maintaining contact with the plurality of foot and hand spines 16a, 16d, 18a, 18b. As will be explained in more detail below, each of the foot and hand spines 16a, 16b, 18a, 18d is decoupled from each other, that is, each of the foot and hand spines 16a, 16b, 18a, 18d is configured with independent rotational and lateral movement.

[0026] Referring again to Fig. 1, the base assembly 14 includes a floor assembly 20 and a column assembly 22 extending in a generally upward direction from the floor assembly 20. The floor assembly 20 is configured to provide a stable base for the simulator 10 and includes a plurality of support members 24a-24c. In the illustrated embodiment, the support members 24a, 24b have a parallel arrangement and the support member 24c is positioned in a perpendicular orientation between the support members 24a, 24b and is configured as a connector for the support members 24a, 24b. However, in alternate embodiments, the floor assembly 20 can have other structures, systems, mechanisms, and devices configured to provide a stable base for the simulator 10.

[0027] Referring again to Fig. 1, the column assembly 22 has a first end 26 that is connected to the floor assembly 20 and an opposing second end 28. The column assembly 22 is configured to support the framework 12 in a vertically upward position as the framework 12 rotates about an axis A— A extending in a generally horizontal orientation at the second end 28 of the column assembly 22.

[0028] Referring again to Fig. 1, the column assembly 22 has a first leg 30 and a second leg 32. The legs 30, 32 have an angled orientation and cooperate to form a recess 34 between the first and second ends 26, 28. The recess 34 is configured to • provide clearance for the arms and legs of a user as the framework 12 rotates about an axis A— A. It should be appreciated that the column assembly 22 can have any structures, systems, mechanisms, and orientation sufficient for the functions described herein.

[0029] Referring again to F ig . 1 , the hand spine 18a includes a hand handle 44 configured for axial travel along the length of the hand spine 18a. In a similar manner, the hand spine 18b includes a hand handle 46 that is configured for axial travel along the length of the hand spine 18b. The axial travel of the hand handle 44 along the length of the hand spine 18a is independent of the axial travel of the hand handle 46 along the length of the hand spine 18b.

[0030] Referring again to Fig. 1, the foot spine 16a includes a footrest 48 configured for axial travel along the length of the foot spine 16a. In a similar manner, the foot spine 16b includes a footrest 50 that is configured for axial travel along the length of the foot spine 16b. The axial travel of the footrest 48 along the length of the foot spine 16a is independent of the axial travel of the root rest 50 along the length of the foot spine 16b. It should also be appreciated that the axial travels of the hand handles 44, 46 are independent of the axial travels of the footrests 48, 50.

[0031] Referring again to Fig. 1, each of the foot and hand spines 16a, 16b, 18a, 18b is formed from a structural member, such as the non-limiting example of steel tube. However, in other embodiments, each of the foot and hand spines 16a, 16b, 18a, 18b can be formed from other desired materials or combinations of materials, sufficient for the functions described herein.

[0032] Referring again to Fig. 1, as each of the hand spines 16a, 16b move in the x, z and rotational directions, each of the hand handles 44, 46 moves accordingly. In this manner, the changing positions of the hand handles 44, 46 enable the hands of the user to be alternately either closer to each other or further apart from each other, thereby advantageously enhancing the simulated action or movement of crawling up or down a mountain and instilling a level of mountain fitness to a user.

[0033] Referring again to Fig. 1, as each of the foot spines 16a, 16b move in the x, z and rotational directions, each of the footrests 48, 50 moves accordingly. In this manner, the changing positions of the footrests 48, 50 enable the feet of the user to be alternately either closer to each other or further apart from each other, thereby advantageously enhancing the simulated action or movement of crawling up or down a mountain and instilling a level of mountain fitness to a user.

[0034] Referring again to Fig. 1, each of the foot spines 16a, 16b and each of the hand spines 18a, 18b are pivotally mounted to a hub section 40. In the illustrated embodiment, the hub section 40 includes one or more rotating mechanisms, or axles 60, configured to receive each of the foot spines 16a, 16b and each of the hand spines 18a, 18b in a manner to facilitate pivotal movement. However, in alternate embodiments, each of the foot spines 16a, 16b and each of the hand spines 18a, 18b can be supported by the framework with other structures, mechanisms, and devices sufficient to facilitate pivotal movement.

[0035] Referring again to Fig. 1, the hub section 40 includes a padded chest protector 54. The padded chest protector 54 is configured for contact with the chest of the user. The padded chest protector 54 is further configured to injury to the user during use of the simulator 10.

[0036] Referring again to Fig. 1, the floor assembly 20 and the column assembly 22 cooperate to form a fulcrum, thereby facilitating rotational movement of the framework 12, as represented by movement arrows R2, R3. Rotation of the framework 12 about the axis A--A is actuated by a motor 64. In the illustrated embodiment, the motor 64 has the form of an electric motor. The electric motor can have any desired form, such as the non-limiting example of a servo motor configured for precise rotational movement of the framework 12 and can have any desired source of electrical power, including the non-limiting example of battery power. However, in other embodiments, other devices can be used sufficient to facilitate rotational movement of the framework 12.

[0037] Referring again to Fig. 1, a controller 66 is used to control the motor 64. The controller 66 can have any form and configuration sufficient to control the motor 64. It is further contemplated the controller 66 can be programmed with pre- defined rotational movements, such as to define a workout routine. The pre-defined workout routines can vary the rotational movement of the framework 12 and the foot and hand spines 16a, 16b, 18a, 18b, thereby varying the intensity /resistance in regard to the simulated motion of crawling up or down a mountain. It should be appreciated that the simulator 10 can incorporate other structures, mechanisms, and devices to adjust the intensity/resistance in regard to the simulated motion of crawling up or down a mountain. Nonlimiting examples of other mechanisms include pneumatic devices, geared mechanisms, banded mechanisms, and the like.

[0038] Referring again to Fig. 1 and as described above, the framework 12 rotates about the one or more rotating mechanisms, or axles 60, extending from the second end 28 of the column assembly 22. At the same time, each of the foot and hand spines 16a, 16b, 18a, 18b are configured for independent movement in the x, z, and RI directions. In addition, and also simultaneously, each of the hand handles 44, 46 and footrests 48, 50 are independently configured for axial movement along the lengths of their respective foot and hand spines 16a, 16b, 18a, 18b. Advantageously, the movement features combine to vary the intensity /resistance with regard to the simulated motion of crawling up or down a mountain.

[0039] Referring now to Figure 2, an exploded view of one embodiment of a motor drivetrain 70 is shown. The hub section 40 is connected to the rotating mechanism, or axle 60, the motor 64, ball bearings 61, geared transmission 62, and shaft coupler 63. These components, using the mechanical power provided by the motor, enable the axle 60 to rotate the hub 40 in a 360-degree motion, R2. In other embodiments, various components can be incorporated into the motor drivetrain sufficient to facilitate rotational movement of the hub 40.

[0040] Referring now to Figure 3, an exploded view of one embodiment of the hub section 40 is shown. Each of the foot spines 16a, 16b and each of the hand spines 18a, 18b are independently connected to and supported by separate pivot points positioned within the hub section 40, thereby facilitating independent movement of each of the foot and hand spines 16a, 16b, 18a, 18b. The hand spine 18a is supported by the hub section 40 for movement in the x and z directions as well as rotational movement as depicted by direction arrow R4. The hub section 40 supports the hand spine 18b and the foot spines 16a, 16b in a manner such as to facilitate similar directional movements. In this manner, the separate movements of the hand and foot spines 16a, 16b, 18a, 18b are decoupled from each other. In the illustrated embodiment, the pivot points of 18a and 18b are shown in the form of electric magnetic connection, whereas the pivot points of 16a and 16b are shown as hinges 43. Gears 42 are shown as a part of a Gear and Pulley system (pulleys not shown for clarity), to depict the internal components that drive the movement. It should be noted, however, that these internal pivot points can have any desired form, configured to facilitate the decoupled lateral and rotational movements of each of the foot spines and hand spines.

[0041] Referring now to Figs. 4-13, various combinations of the movement features are illustrated. Referring now to Fig. 4, movement of various portions of the framework 12 is illustrated. The framework 12 remains in a generally vertical orientation with the foot spines 16a, 16b extending in a generally downward vertical direction and the hand spines 18a, 18b extending in a generally upward direction. In this illustration, the foot spines 16a, 16b remain parallel to each other and the hand spines 18a, 18b remain parallel to each other. Further to this illustration, the hand handle 44 has moved in an axial direction to a distal end of the hand spine 18a, the hand handle 46 has moved in an axial direction to a proximate midpoint of the hand spine 18b, the footrest 48 has moved in an axial direction toward the hub section 40 and the footrest 50 has moved in an axial direction toward the distal end of the foot spine 16b. Still further to this illustration, each of the foot spines 16a, 16b and each of the hand spines 18a, 18b have no directional nor rotational movements.

[0042] Referring now to Fig. 5, counterclockwise rotational movement of the framework 12 (as represented by direction arrows R2) about axis A--A is illustrated with the foot spines 16a, 16b, hand spines 18a, 18b, hand handles 44, 46 and footrests 48, 50 remaining the same positions as shown in Fig. 4 and described above.

[0043] Referring now to Fig. 6, further counterclockwise rotational movement of the framework 12 (as represented by direction arrows R2) about axis A— A is illustrated with the foot spines 16a, 16b remaining parallel to each other and the hand spines 18a, 18b remaining parallel to each other. Further to this illustration, the hand handle 44 has moved in an axial direction toward the hub section 40, the hand handle 46 has moved in an axial direction to the distal end of the hand spine 18b, the footrest 48 has moved in an axial direction toward the distal end of the foot spine 16a and the footrest 50 has moved in an axial direction toward the hub section. Still further to this illustration, each of the foot spines 16a, 16b and each of the hand spines 18a, 18b have no directional nor rotational movements.

[0044] Further shown Figure 6 is the addition of a user attachment device 41, which may be in the form of a harness. A harness may be incorporated onto the hub section 40 to enable a user to securely attach his or her body to the framework while it is being rotated along axis A— A. It should be appreciated that other structures, mechanisms, and devices to securely connect a user to the framework may be used. Non-limiting examples of other attachment devices include straps, garments, Velcro, and the like.

[0045] Referring now to Fig. 7, further counterclockwise rotational movement of the framework 12 (as represented by direction arrows R2) about axis A— A is illustrated with the foot spines 16a, 16b remaining parallel to each other and the hand spines 18a, 18b remaining parallel to each other. In this position, the framework 12 is nearly inverted from that shown in Fig. 1. Further to this illustration, the hand handles 44, 46 and the footrest 48 remain in the same position as shown in Fig. 4. The footrest 50 has moved in an axial direction toward the distal end of the foot spine 16b. Still further to this illustration, each of the foot spines 16a, 16b and each of the hand spines 18a, 18b have no directional nor rotational movements.

[0046] Referring now to Fig. 8, continued counterclockwise rotational movement of the framework 12 (as represented by direction arrows R2) about axis A— A is illustrated with the foot spines 16a, 16b, hand spines 18a, 18b, hand handles 44, 46 and footrests 48, 50 remaining the same positions as shown in Fig. 5 and described above. Still further to this illustration, each of the foot spines 16a, 16b and each of the hand spines 18a, 18b have no directional nor rotational movements.

[0047] Referring now to Fig. 9, continued counterclockwise rotational movement of the framework 12 (as represented by direction arrows R2) about axis A— A is illustrated with the foot spines 16a, 16b, hand spines 18a, 18b, hand handles 44, 46 and footrests 48, 50 remaining the same positions as shown in Fig. 5 and described above. Still further to this illustration, each of the foot spines 16a, 16b and each of the hand spines 18a, 18b have no directional nor rotational movements.

[0048] Referring now to Fig. 10, further counterclockwise rotational movement of the framework 12 (as represented by direction arrows R2) about axis A— A is illustrated. With this rotation, the framework 12 has completed a full rotation and is nearly in the same orientation as that shown in Fig. 1 with the foot spines 16a, 16b remaining parallel to each other. The distal ends of the hand spines 18a, 18b have been moved in opposing x directions such that the distal ends are further apart than that shown in Fig. 5. Further to this illustration, the hand handle 44 has moved in an axial direction toward the distal end of the hand spine 18a, the hand handle 46 has moved in an axial direction to a proximate midpoint of the hand spine 18b, the footrest 48 has moved in an axial direction toward the hub section 40 and the footrest 50 has moved in an axial direction toward the distal end of the foot spine 16b. Still further to this illustration, each of the foot spines 16a, 16b and each of the hand spines 18a, 18b have no rotational movements.

[0049] Referring now to Fig. 11, the framework 12 remains in the same rotational orientation as shown in Fig. 10. In this position, the foot spines 16a, 16b remain parallel to each other, however the footrest 48 has moved in an axial direction toward the distal end of the foot spine 16a and the footrest 50 has moved in an axial direction toward the hub section 40. The distal ends of the hand spines 18a, 18b continue movement in opposing x directions such that the distal ends are further apart than that shown in Fig. 9. Further to this illustration, the hand handle 44 has moved in an axial direction toward the hub section 40 and the hand handle 46 has moved in an axial direction toward the distal end of the hand spine 18b. Still further to this illustration, each of the foot spines 16a, 16b and each of the hand spines 18a, 18b have no rotational movements.

[0050] Referring now to Fig. 12, the framework 12 remains in the same rotational orientation as shown in Fig. 10. In this position, the foot spines 16a, 16b remain parallel to each other, however the footrest 48 has moved in an axial direction toward the hub section 40 and the footrest 50 has moved in an axial direction toward the distal end of the foot spine 16b. The distal end of the hand spine 18a has been moved in an x direction. The distal end of the hand spine 18b has been moved in both an x direction and a z direction such that the distal ends of the hand spines 18a, 18b are further apart in a z direction than that shown in Fig. 9. Further to this illustration, the hand handle 44 has moved in an axial direction toward the distal end of the hand spine 18a and the hand handle 46 has moved in an axial direction toward the hub section 40. Still further to this illustration, each of the foot spines 16a, 16b and each of the hand spines 18a, 18b have no rotational movements.

[0051] Referring now to Fig. 13, the framework 12 remains in the same rotational orientation as shown in Fig. 10. In this illustration, the hand spine 18b is rotated about a vertical axis B— B, as denoted by rotation arrow R4, while the hand spine 18a and the foot spines 16a, 16b remain in a stationary arrangement. It should be appreciated that in other embodiments, any desired quantity of spines could be rotated while the remaining spines are kept in a stationary arrangement.

[0052] While the simulator 10 shown in Figs. 1-13 and described above includes the fram ework 12 pivotally mounted to the base assembly 14, foot spines 16a, 16b, hand spines 18a, 18b and the padded chest protector 54, it should be appreciated that in other embodiments, the simulator 10 can incorporate other structures, methods, and devices sufficient to simulate the action or movement of crawling up or down a mountain.

[0053] As shown in Figs. 1-13, any desired combination of the movement features of the framework 12, foot spines 16a, 16b, hand spines 18a, 18b, hand handles 44, 46 and footrests 48, 50 can be accomplished, thereby advantageously enhancing the simulated action or movement of crawling up or down a mountain and instilling a level of mountain fitness to a user.

[0054] In Figure 14, a second embodiment of the invention, a simulator 100 is shown. Generally, simulator 100 includes a rotatable framework 120 supported by a fixed base assembly 140. The rotatable framework 120 is shown in a first rotational orientation. T h e base assembly 140 includes a floor assembly 200 and a column assembly 220 extending in a generally upward direction from the floor assembly 200. The base assembly 140 is configured to provide a stable base for the simulator 100. However, in alternate embodiments, the base assembly 140 can have other structures, systems, mechanisms, and devices configured to provide a stable base for the simulator 100.

[0055] Referring again to Fig. 14, the base assembly 140 is depicted as a circular shaped fixed frame that supports the framework 120 in its vertically upward position, and as it rotates along the circumference of the base assembly 140. Internally housed along the circumference of the base assembly 140 is a rotating mechanism 160, which is operable as a ball bearing mechanism to assist the framework 120 as it rotates 360 degrees along the circumference of the base assembly 140. It should be appreciated that the base assembly 140 and the rotating mechanism 160 can have any structures, systems, mechanisms, and orientations sufficient for the functions described herein.

[0056] Referring again to Fig. 14, the framework 120 includes a padded chest protector 154. The padded chest protector 154 is configured for contact with the chest of a user, and to prevent injury to the user during use of the simulator 100. Further shown in this Figure is the addition of a user attachment device 141, which may be in the form of a harness. A harness may be incorporated onto the framework 120 to enable a user to securely attach his or her body to the framework while it is being rotated in a 360 degree rotation. It should be appreciated that other structures, mechanisms, and devices to securely connect a user to the framework may be used. Non-limiting examples of other attachment devices include straps, garments, Velcro, and the like.

[0057] Referring to Fig. 15, The rotatable framework 120 includes aplurality of foot spines 160a, 160b configured to support the feet of a user during rotation of the framework 120 and a plurality of hand spines 180a, 180b configured to support the hands of a user during rotation of the framework 120. As the framework 120 rotates, the user incurs exercise in maintaining contact with the plurality of foot and hand spines 160a, 160d, 180a, 180b. As will be explained in more detail below, each of the foot and hand spines 160a, 160b, 180a, 180d is decoupled from each other, that is, each of the foot and hand spines 160a, 160b, 180a, 180d is configured with independent rotational and lateral movement.

[0058] Referring again to Fig. 15, the hand spine 180a includes a hand handle 440 configured for axial travel along the length of the hand spine 180a. In a similar manner, the hand spine 180b includes a hand handle 460 that is configured for axial travel along the length of the hand spine 180b. The axial travel of the hand handle 440 along the length of the hand spine 180a is independent of the axial travel of the hand handle 460 along the length of the hand spine 180b.

[0059] Referring again to Fig. 15, the foot spine 160a includes a footrest 480 configured for axial travel along the length of the foot spine 160a. In a similar manner, the foot spine 160b includes a footrest 500 that is configured for axial travel along the length of the foot spine 160b. The axial travel of the footrest 480 along the length of the foot spine 160a is independent of the axial travel of the footrest 500 along the length of the foot spine 160b. It should also be appreciated that the axial travels of the hand handles 440, 460 are independent of the axial travels of the footrests 480, 500.

[0060] Referring again to Fig. 15, each of the foot and hand spines 160a, 160b, 180a, 180b is formed from a structural member, such as the non-limiting example of steel tube. However, in other embodiments, each of the foot and hand spines 160a, 160b, 180a, 180b can be formed from other desired materials or combinations of materials, sufficient for the functions described herein.

[0061] Referring again to Fig. 15, as each of the hand spines 160a, 160b move in the x, z and rotational directions, each of the hand handles 440, 460 moves accordingly, and in the same orientations as in the first embodiment of this invention. In this manner, the changing positions of the hand handles 440, 460 enable the hands of the user to be alternately either closer to each other or further apart from each other, thereby advantageously enhancing the simulated action or movement of crawling up or down a mountain and instilling a level of mountain fitness to a user.

[0062] Referring again to Fig. 15, as each of the foot spines 160a, 160b move in the x, z and rotational directions, each of the footrests 480, 500 moves accordingly. In this maimer, the changing positions of the footrests 480, 500 enable the feet of the user to be alternately either closer to each other or further apart from each other, thereby advantageously enhancing the simulated action or movement of crawling up or down a mountain and instilling a level of mountain fitness to a user.

[0063] Referring to Fig. 16, the rotational movement of the framework 120, as represented by movement arrows R200 is shown. Further, the rotation of the framework 120 is actuated by a motor, which is embedded in the base assembly 140 and therefore not shown on the exterior of this embodiment. It is contemplated that this motor has the form of an electric motor. However, the motor can have any desired form, such as the non-limiting example of a servo motor configured for precise rotational movement of the rotational mechanism 160, and subsequent rotation of framework 120. The motor can have any desired source of electrical power, including the non-limiting example of battery power. However, in other embodiments, other devices can be used sufficient to facilitate rotational movement of the framework 120.

[0064] Referring again to Fig. 16, a controller, not shown on the exterior of this embodiment, is used to control the motor. The controller can have any form and configuration sufficient to control the motor. It is further contemplated the controller can be programmed with pre- defined rotational movements, such as to define a workout routine. The pre-defined workout routines can vary the rotational movement of the framework 120 and the foot and hand spines 160a, 160b, 180a, 180b, thereby varying the intensity/resistance in regard to the simulated motion of crawling up or down a mountain. It should be appreciated that the simulator 100 can incorporate other structures, mechanisms, and devices to adjust the intensity/resistance in regard to the simulated motion of crawling up or down a mountain. Non-limiting examples of other mechanisms include pneumatic devices, geared mechanisms, banded mechanisms, and the like.

[0065] Referring again to Fig. 16 and as described above, as the framework 120 rotates about the rotating mechanism 160, each of the foot and hand spines 160a, 160b, 180a, 180b are configured for independent movement in the x, y, and z directions. In addition, and simultaneously, each of the hand handles 440, 460 and footrests 480, 500 are independently configured for axial movement along the lengths of their respective foot and hand spines 160a, 160b, 180a, 180b. Advantageously, the movement features combine to vary the intensity/resistance with regard to the simulated motion of crawling up or down a mountain. [0066] The simulator shown by embodiments 10 and 100 provides many benefits, although all benefits may not be present in all embodiments. First, the simulator is configured to simulate the action or movement of crawling up or down a mountain. Second, the simulator is easily adaptable to users of different heights and/or abilities. Third, the simulator includes a motor configured to precisely control rotation of the framework, depicted by 12 and 120, thereby controlling the intensity /resistance of the workout. Fourth, the simulator can be easily programmed with pre-defined workout routines. Finally, the simulator provides a balance between several desired workout benefits, including strength training, cardio training, balance, agility, and coordination.

[0067] In accordance with the provisions of the patent statutes, the principle and mode of operation of the exercise machine and climbing simulator have been explained and illustrated in a certain embodiment. However, it must be understood that the exercise machine and climbing simulator may be practiced otherwise than as specifically explained and illustrated without departing from its spirit or scope.
