Description

BACKGROUND OF THE INVENTION

Technical Field

This invention relates to the general technical field of physical fitness, physical therapy, and exercise equipment and machines. This invention relates more specifically to the field of exercise equipment for simulating a climbing exercise motion.

Prior Art

Exercise, physical fitness, and physical therapy equipment and machines are available in various configurations and for various purposes. In the climbing simulation equipment field, there are generally two categories of machines. One category of products commonly known as stair climbing simulators generally refers to products that comprise a rotating set of stair treads to simulate climbing a staircase. A second category of products commonly known as ladder climbing simulators generally refers to products that comprise opposing pedals and handles that slide on a linear surface of approximately 15 degrees off of vertical to simulate scaling a ladder. While both categories of exercise equipment products are useful and effective, both have deficiencies that can be vastly improved.

U.S. Pat. No. 5,492,515 of Charnitski discloses a “Climbing Exercise Machine” comprising an upright member having a right track and a left track. A first and second truck are mounted in the right track, the first truck having a handle and the second truck having a pedal. A third and fourth truck are mounted in the left track, the third truck having a handle and the fourth truck having a pedal. There is a first connection between the first truck and the second truck, and there is a second connection between said the third truck and the fourth truck. The first truck, the second truck, the third truck, and the fourth truck move in a substantially single plane, which creates a linear climbing motion wherein the user's hands stay connected to the handles and the user's feet stay connected to the pedals during the exercise motion. The primary deficiency of this motion is that it is not the way a human body would naturally move when performing a climbing motion. The multi-joint movement patterns of the human body naturally move in arcing motions for nearly all movement patterns including running, swimming, hiking, climbing, and most other athletic movements.

U.S. Pat. No. 9,216,317 of Golen Jr. et al discloses a “Stair climber apparatuses and methods of operating a stair climber apparatuses” comprising aa frame having an inclined support that extends from a bottom portion to a top portion, a plurality of stairs that are connected together in series and travel in a loop around the inclined support, an electric motor, and a control circuit that controls a speed of the electric motor and an output direction of the electric motor. The electric motor is operatively connected to the plurality of stairs so as to move the plurality of stairs in an upward direction along the inclined support and so as to alternatively move the plurality of stairs in an opposite, downward direction along the inclined support. This is an effective exercise that allows the user to use their own pattern of motion as they step from one stair tread to the next. The first primary deficiency of this exercise is that it does not engage the user's upper body into the exercise motion. The second primary deficiency is that the only force the user works against is gravity as they lift each leg from one stair tread to the next. This type of exercise machine cannot create additional force or resistance for the user to work against. The only way to increase the exercise motion difficulty is to increase the speed at which the stairs rotate such that the user is forced to climb at a faster rate.

An exercise machine that would greatly improve the current state of the art for climbing simulation exercise machines would engage the user's arms and legs into the exercise motion. This machine would also move the user through arcing patterns of motion that are natural to human motion. The user and not the machine would be able to control the range of motion of the exercise. This machine would also be able to apply a plurality of adjustable resistance levels to these arcing motions such that the user could select and set the level of exercise resistance prior to or during the exercise motion. This adjustable resistance would also be able to apply all of the levels of resistance at any speed of the exercise motion.

BRIEF SUMMARY OF THE INVENTION

The present invention provides a climbing simulation exercise machine. In a first embodiment, the machine is supported by a stationary support frame. A set of left and right arc shaped wheel tracks are mounted on the stationary support frame. Left and right pedal assemblies are movably engaged with the left and right arc shaped wheel tracks. The first ends of left and right handle levers that support and engage the user's arms are pivotally mounted on the stationary support frame and the second end of the left and right handle levers comprise at least one handle. Left and right linkages connection hubs are mounted on the stationary support frame. A rocker lever with left and right ends and an axle shaft is pivotally mounted on the stationary support frame.

First and second left linkage bars connect the left pedal assembly with the left linkages connection hub and first and second right linkage bars connect the right pedal assembly with the right linkages connection hub. A left pedal and in certain embodiments a shin pad are connected to the first left linkage bar with a connection tube that is mounted on the left pedal assembly. A right pedal and in certain embodiments a shin pad are connected to the first right linkage bar with a connection tube that is mounted on the right pedal assembly. A third left linkage bar connects the left linkages connection hub with the left end of the rocker lever and a third right linkage bar connects the right linkages connection hub with the right end of the rocker lever. A fourth left linkage bar connects the left handle lever with the left linkages connection hub and a fourth right linkage bar connects the right handle lever with the right linkages connection hub.

During operation of the machine, the left foot pedal moves in the opposite direction of the right foot pedal. During operation of the machine, the left handle lever moves in the opposite direction of the right handle lever. The left side pedal, the right side pedal, the left handle lever, and the right handle lever all move in reciprocating arcing motions. The motions of left side pedal, the right side pedal, the left handle lever, and the right handle lever always move concurrently and the motions are synchronized by the motion of the rocker arm. This embodiment of the invention can be operated without a resistance mechanism or with a resistance mechanism to resist the motion of the left side pedal, the right side pedal, the left handle lever, and the right handle lever. The preferred resistance mechanism is a compression friction resistance. However, other forms of resistance can operate with the machine, including but not limited to, magnetic resistance, air displacement resistance, fluid displacement resistance, spring tension resistance, flywheel based resistance mechanisms, or combinations thereof.

In a second embodiment of the invention, the components of the machine as described cooperate and function as in the first embodiment with the exception that the left and right handle levers are not pivotally mounted on the stationary support frame but are rigidly connected to the left and right linkages connection hubs, and the fourth left and right linkage bars are removed. This embodiment of the invention can be operated without a resistance mechanism or with a resistance mechanism to resist the motion of the left side pedal, the right side pedal, the left handle lever, and the right handle lever. The preferred resistance mechanism is a compression friction resistance. However, other forms of resistance could operate with the machine including but not limited to, magnetic resistance, air displacement resistance, fluid displacement resistance, spring tension resistance, flywheel based resistance mechanisms, or combinations thereof.

The invention is comprised of many identical left and right components as illustrated in various perspective views and many of these components will frequently be referred to and described in a plural context so as to prevent the duplication of descriptions of identical left and right components. Many of these components will have the same identification number and will frequently be referred to as a left or right component. A “left” or “left side” component or set of components will refer to those that would be on the user's left side of the machine when the user is mounted on the machine and a “right” or “right side” component or set of components will refer to those that would be on the user's right side of the machine when the user is mounted on the machine.

Also, it is to be understood that when components or sets of components that have been identified at least once as being duplicates on the left and right sides of the machine are described as cooperating with or being connected to other components or sets of components that have been identified at least once as being duplicates on the left and right sides of the machine, that left side components or sets of components will cooperate with or connect to left side components and right side components or sets of components with cooperate with or connect to right side components.

There are two preferred embodiments of the invention and each embodiment is presented with and without a resistance system. Many of the components are common to both embodiments and those common components are presented with the same individual reference numeral for all illustrations to prevent excessive duplication of description.

FIGS. 1-25 are all views of embodiments of the invention this inventor refers to as a “Climbing simulation exercise machine”. Generally, the invention is a machine that places the user in a mostly vertical forward leaning climbing position while exercising. In each embodiment the user's arms move in forward and rearward reciprocating arcing motions while the user's legs concurrently move in forward and rearward reciprocating arcing motions. While performing this exercise, the user's left arm and left leg move in opposite directions and the user's right arm and right leg move in opposite directions. During this exercise motion, while one arm is moving in a pushing direction, the other arm is moving in a pulling direction, and while one leg is moving in a pushing direction, the other leg is moving in a pulling direction. These exercise motions of the user's arms and legs are synchronized such that the user's arms and legs move in unison. The exercise motion of each embodiment will function without a resistance mechanism. However, the preferred embodiments are operatively coupled with a resistance mechanism and the preferred resistance mechanism is a compression friction resistance mechanism.

FIGS. 1-7 and 19-25 illustrate various views of the embodiments of machine 1 and machine 1A respectively to provide a more complete understanding of the invention. FIGS. 8-18 illustrate various views of a resistance mechanism 40 to provide a more complete understanding of this preferred resistance mechanism 40 that can be operatively coupled with machine 1 and machine 1A. Certain components of machine 1 and machine 1A are shared with resistance mechanism 40 and machine 1 or machine 1A or resistance mechanism 40 preferably comprise those shared components.

Now referring to FIGS. 1-7 and 19, FIGS. 1-7 and 19 are detailed drawings of the components, structures, and assemblies that create a first preferred embodiment of a climbing simulation exercise machine 1. FIGS. 1-5 and 19 represent a machine 1 combined with a resistance mechanism 40. FIGS. 6 and 7 represent a machine 1 with no resistance mechanism.

As best illustrated in FIGS. 1-7, machine 1 comprises a stationary support frame 2 and left and right wheel tracks 3 are rigidly connected to rearward and central sections of stationary support frame 2. Left and right pedal assemblies 20 are pivotally mounted on left and right wheels 25 with left and right wheel axles 26, and wheels 25 are rollably engaged with wheel tracks 3. First left and right linkage bars 7 and second left and right linkage bars 8 connect pedal assemblies 20 to left and right linkage connection hubs 4. Linkage connection hubs 4 are pivotally mounted on a forward section of stationary support frame 2. Pivot hubs 13 are pivotally mounted on another section of stationary support frame 2 forward of linkage connection hubs 4. Left and right handles 6 are rigidly mounted on left and right handle levers 5 and handle levers 5 are rigidly mounted on pivot hubs 13. Pivot hubs 13 are operatively connected to linkages connection hubs 4 with fourth left and right linkage bars 10. A rocker lever 11 is pivotally mounted on a forward section of stationary support frame 2 and rocker lever 11 is operatively connected to linkages connection hubs 4 with third left and right linkage bars 9.

As best illustrated in FIGS. 1-5, machine 1 is operatively connected with a resistance mechanism 40 and a resistance adjustment assembly 50. Resistance mechanism 40 and resistance adjustment assembly 50 are operatively mounted on a forward section of stationary support frame 2. Resistance mechanism 40 and resistance adjustment assembly 50 will be further described in detail herein.

Stationary support frame 2 is comprised of multiple structural metal components of various shapes and size capable of supporting the operable components of machine 1 and a user U when operating machine 1. A receiving plate 14 is rigidly mounted on a central section of stationary support frame 2 for receiving a mounting plate 15. Wheel tracks 3 are rigidly attached to stationary support frame 2 and are represented as arc shaped metal tubes or bars that are capable of supporting the smooth rolling movement of pedal assembly 20.

Pedal assembly 20 is comprised of identical left are right components as follows. Wheels 25 are represented as concave surface wheels that are mounted on wheel axles 26 and roll along the round surface of wheel tracks 3. Pedal frames 22 are most U shaped metal plates that are pivotally mounted on wheel axles 26 and pedals 21 are rigidly mounted on central and rearward sections of pedal frames 22. First ends of support tubes 23 are rigidly connected at an obtuse angle to forward sections of pedal frames 22. Shin pads 24 are rigidly mounted on the second ends of support tubes 23.

The first ends of first linkage bars 7 are rigidly connected to a central section of support tubes 23 and the second ends of first linkage bars 7 are pivotally connected to the first ends of second linkage bars 8. The second ends of second linkage bars 8 are rigidly connected to first sections of linkages connection hubs 4.

Handles 6 and handle levers 5 are represented as shaped metal tubes. Handles 6 are rigidly connected to first ends of handle levers 5 and the second end of handle levers 5 are rigidly connected to first sections of pivot hubs 13.

Pivot hubs 13 are elongated cylinders and first ends of left and right triangular shaped connection flanges 35 are rigidly connected to second sections of pivot hubs 13. Left and right connection bosses 35A are rigidly mounted on second ends of connection flanges 35.

Linkage connection hubs 4 are elongated cylinders and first ends of left and right connection flanges 36 are rigidly connected to second sections of linkage connection hubs 4. Left and right connection bosses 36A are rigidly mounted on second ends of connection flanges 36.

First ends of fourth left and right linkage bars 10 are pivotally connected to connection bosses 35A and the second ends of fourth linkage bars 10 are pivotally connected to a first end of connection bosses 36A.

The first ends of third left and right linkage bars 9 are pivotally connected to the second ends of connection bosses 36A. The second end of third left side linkage bars 9 are pivotally connected to the left side end of rocker lever 11. The second end of third right side linkage bar 9 is pivotally connected to the right side end of rocker lever 11.

Rocker lever 11 is represented as a diamond shaped flat piece of metal but also can be constructed of other elongated shapes or materials to achieve the same function. The center section of rocker lever 11 is pivotally mounted on axle shaft 12 and axle shaft 12 is rigidly mounted on a central section of a mounting plate 15. Preferred embodiments of machine 1 are structured to function with rocker lever 11 and axle shaft 12. Preferred embodiments of resistance mechanism 40 are structured to function with rocker lever 11 and axle shaft 12. Rocker lever 11 connects and synchronizes the left side exercise motion components of machine 1 with the right side exercise motion components of machine 1 as will be further described in detail herein. The motion of rocker lever 11 also propels the motion of the friction resistance created by resistance mechanism 40 as will be further described in detail herein.

FIG. 4 illustrates a user U operating machine 1. In the configuration of machine 1 in FIG. 4, User U's shins are supported by shin pads 24. However, user U can also operate machine 1 without the support of shin pads 24. FIG. 5 illustrates the machine 1 without shin pads 24. In this configuration of machine 1, left and right support tubes 23A are presented as shorter tubes so as to not obstruct the motion of a user U during operation of machine 1.

As illustrated in FIG. 4, to operate machine 1, a user U mounts machine 1 by placing the bottoms of user U's feet on pedals 21 while resting user U's shins, ankles, and the tops of user U's feet against shin pads 24. User U also grasps handles 6. User U then begins the exercise motion by urging the left handle 6 in the opposite direction of right handle 6 while concurrently urging the left pedal 21 and left shin pad 24 in the opposite direction of the right pedal 21 and right shin pad 24. For example, In a first direction, if user U urges left handle 6 forward in a pushing motion, user U will be urging left pedal 21 and left shin pad 24 rearward in a pushing motion, and concurrently user U will be urging right handle 6 rearward in a pulling direction and urging right pedal 21 and right shin pad 24 forward in a pulling motion. When user U reaches the desired range of motion in the first direction, then user U at user U's sole discretion and not caused by the mechanical features of the machine, will reverse the motions to a second direction so as to urge left handle 6 rearward in a pulling motion, and to urge left pedal 21 and left shin pad 24 forward in a pulling motion, while concurrently urging right handle 6 forward in a pushing direction and urging right pedal 21 and right shin pad 24 rearward in a pushing motion. During the pushing motions, the bottoms of user U's feet engage and push against pedal 21 while the user's legs are stabilized by shin pads 24. During the pulling motions, the bottom of user U's feet are supported by pedals 21 while user U pulls against shin pads 24 with user U's ankles and the tops of user U's feet. In other words, the unique configuration of machine 1 allows user U's feet and ankles to be wedged in between pedals 21 and shin pads 24 to allow user U to engage all of the muscle groups of user U's legs, hips, and buttocks in a first pushing motion and a second pulling motion to achieve maximum exercise efficiency.

During operation in a first direction motion of the left side components of machine 1, when left pedal assembly 20 moves rearward along left wheel carriage track 3, this causes first left linkage bar 7 to move rearward and the second end of first left linkage bar 7 to pivot on the first end of second left linkage bar 8. This causes the first end of second left linkage bar 8 to swing rearward as the second end of second left linkage bar 8 pivots on left linkages connection hub pivot 4. Concurrent to this motion the left handle lever 5 and left handle 6 pivot forward about left pivot hub 13 as left pivot hub 13 rotates forward. This causes fourth left linkage bar 10 to move forward as the first end of fourth left linkage bar 10 pivots on connection boss 35A. This causes the second end of fourth left linkage bar 10 to pivot on left connection boss 36A as left linkages connection hub pivot 4 rotates forward. This causes third left linkage bar 9 to move upward as the first end of third left linkage bar 9 pivots on left connection boss 36A and the second end of third left linkage bar 9 pivots on the left end of rocker lever 11. This causes the left end of rocker lever 11 to move upward as the center section of rocker lever 11 pivots about axle shaft 12.

During operation in a first direction motion of the right side components of machine 1, when right pedal assembly 20 moves forward along right wheel carriage track 3, this causes first right linkage bar 7 to move forward and the second end of first right linkage bar 7 to pivot on the first end of second right linkage bar 8. This causes the first end of second right linkage bar 8 to swing forward as the second end of second right linkage bar 8 pivots on right linkages connection hub pivot 4. Concurrent to this motion the right handle lever 5 and right handle 6 pivot rearward about right pivot hub 13 as right pivot hub 13 rotates rearward. This causes fourth right linkage bar 10 to move rearward as the first end of fourth right linkage bar 10 pivots on connection boss 35A. This causes the second end of fourth right linkage bar 10 to pivot on right connection boss 36A as right linkages connection hub pivot 4 rotates rearward. This causes third right linkage bar 9 to move downward as the first end of third right linkage bar 9 pivots on right connection boss 36A and the second end of third right linkage bar 9 pivots on the right end of rocker lever 11. This causes the right end of rocker lever 11 to move downward as the center section of rocker lever 11 pivots about axle shaft 12.

During operation of a second direction motion of the left and right side components of machine 1, the motions are reversed from the first direction motion of the left and right side components of machine 1 as previously descried herein. During the first or second direction motions of all embodiments of the invention, user U is in total control of the range of the exercise motions for all embodiments of the invention without having to making any adjustments to any of the features or components of any embodiment of the invention. In other words, user U can properly operate any embodiment of the invention by moving pedal assemblies 20 and handle levers 5 any distance in a forward or rearward motion simply by how far they choose to push or pull pedal assemblies 20 and handle levers 5. No components of any embodiments of the invention require the user U to move pedal assemblies 20 or handle levers 5 any preset distance to properly operate machine 1.

Now referring to FIGS. 8-19, FIGS. 8-19 are detailed drawings of the components, structures, and assemblies that create the resistance mechanism 40. This preferred resistance mechanism 40 creates a compression friction resistance force against the exercise motion components of machine 1 and machine 1A. There are certain common components that are required for the proper operation of resistance mechanism 40 that are also required for the proper operation of machine 1 and machine 1A. These common components are identified with the same reference numerals when being referenced in the description of the function of resistance mechanism 40 or machine 1 or machine 1A.

As best illustrated in FIG. 8, a mounting plate 15 supports an axle shaft 12 and two anchor shafts 42, such that axle shaft 12 is rigidly mounted on a central section of mounting plate 15 and anchor shafts 42 are rigidly mounted on outer sections of mounting plate 15. A compression component 43 is movably mounted on axle shaft 12 proximal to a first end of axle shaft 12 and a cap plate 46 is rigidly mounted on axle shaft 12 proximal to a second end of axle shaft 12. A rocker lever 11 is movably mounted on axle shaft 12 between compression component 43 and cap plate 46. A friction plate 45 is movably mounted on axle shaft 12 between rocker lever 11 and cap plate 46. The first ends of third left and right linkage bars 9 are pivotally connected proximal to opposing ends of rocker lever 11. A first end of a movement lever 44 is rigidly connected to an outer section of compression component 43 and a second end of movement lever 44 is pivotally connected to a first end of linkage bar 55. The second end of linkage bar 55 is pivotally connected to a resistance adjustment assembly 50

As best illustrated in FIG. 10, mounting plate 15 is represented as an elongated somewhat rectangular metal plate comprising four mounting holes 16 for securing mounting plate 15 to machine 1 or machine 1A.

FIG. 19 is illustrated with a portion of stationary support frame 2 removed to provide a clearer view of how resistance mechanism 40 is mounted in machine 1 and machine 1A and how resistance mechanism 40 cooperates with the mechanical components of machine 1 and machine 1A. Mounting plate 15 is rigidly connected to receiving plate 14 with fasteners 33 and receiving plate 14 is rigidly connected to stationary support frame 2. Axle 52 is rigidly connected to stationary support frame 2 forward of mounting plate 15.

As best illustrated in FIGS. 9, 10, and 16, axle shaft 12 is represented as a circular metal shaft comprising axle shaft compression threads 12A proximal to a first end for cooperating with the threads 43A of compression component 43. The second end of axle shaft 12 comprises cap threads 12B for cooperating with a fastener 19.

As best illustrated in FIGS. 8, 10, and 17, first and second anchor shafts 42 are represented as metal cylinders with internal threads for accepting fasteners 17. As illustrated in FIGS. 8 and 17, first ends of anchor shafts 42 are rigidly connected to mounting plate 15 and second ends of anchor shafts 42 are rigidly connected to opposing ends of cap plate 46 with fasteners 17. The purpose of anchor shafts 42 is to restrain the movement of cap plate 46 during the operation of resistance mechanism 40. One or more anchor shafts 42 can be mounted at various locations on mounting plate 15 or stationary support frame 2 to achieve the movement restraint of cap plate 6.

As best illustrated in FIGS. 8, 9, 12, and 17, compression component 43 is a metal cylinder with a center hole and internal compression threads 43A. Compression threads 43A function like a nut fastener to cooperate with the external compression threads 12A of axle shaft 12. The shape of compression component 43 includes a flange that extends from the outer perimeter of compression component 43 and a first end of a movement lever 44 is rigidly connected to said flange. A first flat surface of compression component 43 is in cooperative contact with a first flat surface of rocker lever 11. The function of compression component 43 is to increase, decrease, and maintain the compression force on resistance mechanism 40. A threaded component such as compression component 43 is the most common way to create this function. However, other components can create a similar function such as a set of rotational ramps.

As best illustrated in FIGS. 8, 11, and 13, rocker lever 11 is represented as a flat metal plate comprising a central aperture 11A for mounting rocker lever 11 onto axle shaft 12. A first flat surface of rocker lever 11 is in cooperative contact with a first flat surface of compression component 43. Opposing ends of rocker lever 11 comprise first and second apertures 11B for accepting fasteners 18. A fastener 18 pivotally connects the second end of third left linkage bar 9 to the left end of rocker lever 11 and a fastener 18 pivotally connects the second end of third right linkage bar 9 to the right end of rocker lever 11. Apertures 11B are spaced from the second ends of third linkage bars 9 by first and second spacers 32 such that third linkage bars 9 can move freely during operation of resistance mechanism 40 by preventing contact of third linkage bars 9 with rocker lever 11.

As best illustrated in FIGS. 8, 14, and 18, friction disc 45 is represented as a round disc comprising a central aperture 45A for mounting friction disc 45 onto axle shaft 12. A first flat surface of friction disc 45 is in cooperative contact with a second flat surface of rocker lever 11 and a second flat surface of friction disc 45 is in cooperative contact with a first flat surface of cap plate 46. Friction disc 45 is represented as being loosely mounted on axle shaft 12 which is the most practical for long term durability and serviceability of resistance mechanism 40; however, friction disc 45 can be rigidly connected to rocker lever 11 or cap plate 46 and achieve a same or similar function of resistance mechanism 40. Friction disc 45 can be constructed of various materials including but not limited to carbon fiber, fiber glass, felt, leather, and composites of these or other materials.

As best illustrated in FIGS. 8, 15, and 16, cap plate 46 is represented as a flat metal plate comprising a central aperture 46A for securing cap plate 46 to the second end of axle shaft 12 with cap threads 12B and a fastener 19. A first flat side of cap plate 46 is in cooperative contact with a second flat side of friction disc 45. Cap plate 46 also comprises first and second apertures 46B on opposing outer ends of cap plate 46 for securing cap plate 46 to first and second anchor shafts 42 so as to restrain movement of cap plate 46 during operation of resistance mechanism 40. The movement of cap plate 46 can be restrained with various methods and those other methods could require a different shape for cap plate 6.

Preferred embodiments of resistance mechanism 40, machine 1, and machine 1A are structured to function with third left and right linkage bars 9. As previously described, third left and right linkage bars 9 operatively connect the exercise motion components of machine 1 and machine 1A to resistance mechanism 40.

As best illustrated in FIGS. 8-10 and 17-19, resistance adjustment assembly 50 is comprised of an adjustment lever 51, an axle 52, a connection boss 53, and an adjustment handle 54. A central section of adjustment lever 51 is pivotally mounted on axle 52 for reciprocal pivotable movement about axle 52. Connection boss 53 is rigidly connected proximal to a first end of resistance lever 51 and below axle 52. Connection boss 53 is pivotally connected to a second end of linkage bar 55 with a fastener 18. A first end of linkage bar 55 is pivotably connected to the second end of movement lever 44. Adjustment lever handle 54 is rigidly connected proximal to the second end of resistance lever 51 and above axle 52.

Adjustment lever 51 is represented as an elongated formed sheet metal component with an elongated rod rigidly connected to adjustment lever 51 to form the second end of adjustment lever 51 such that the formed sheet metal and the rod together form the adjustment lever 51. The adjustment lever 51 can be configured in various forms including an elongated tube, pipe, plate or the like and perform the same function.

Axle 52 is a rigid circular shaped elongated rod sturdy enough to support the structure and function of the adjustment lever 5.

Connection boss 53 is represented as an elongated metal rod that extends through the first end of adjustment lever 51 and extends to be spaced from one side of adjustment lever 51 for receiving a fastener 18. The function of connection boss 53 is to secure a second end of linkage bar 55 to resistance adjustment assembly 50 with a connection that spaces the second end of linkage bar 55 from adjustment lever 51 so as to allow linkage bar 55 to rotate freely and not contact adjustment lever 51 during movement of adjustment lever 51.

Adjustment lever handle 54 is represented as round rigid component that is rigidly attached to second end of adjustment lever 51. However, various shapes and material can be substituted for adjustment lever handle 54 to create the same function of adjustment lever handle 54. The function of adjustment lever handle 54 is to be the engagement feature that an exercise machine user would engage to adjust the level of resistance on resistance mechanism 40 while operating machine 1 or machine 1A.

Prior to or during operation of machine 1 or machine 1A, resistance mechanism 40 can be adjusted as follows.

To increase the resistance created by resistance mechanism 40, a user U grasps adjustment lever handle 54 and urges resistance lever 51 in a first direction causing adjustment lever 51 to pivot about axle 52. This causes connection boss 53 to move in a first direction, causing linkage bar 55 to move in a first direction, causing movement lever 44 to move in a first direction to rotate compression component 43 on axle 12. This causes compression threads 43A to cooperate with compression threads 12A causing compression component 43 to move along axle shaft 12 and towards rocker lever 11 which increases the compression force on the contact surfaces of the compression component 43 with the rocker lever 11, the contact surfaces of the rocker lever 11 with the friction plate 45, and the contact surfaces of the friction plate 45 with the cap plate 46. This increased compression force increases the force required to move rocker lever 11, linkage bars 9, and the exercise motion components of machine 1 or machine 1A.

To decrease the resistance created by resistance mechanism 40, a user U grasps adjustment lever handle 54 and urges resistance lever 51 in a second direction causing adjustment lever 51 to pivot about axle 52. This causes connection boss 53 to move in a second direction, causing linkage bar 55 to move in a second direction, causing movement lever 44 to move in a second direction to rotate compression component 43 on axle 12. This causes compression threads 43A to cooperate with compression threads 12A causing compression component 43 to move along axle shaft 12 and away from rocker lever 11 which decreases the compression force on the contact surfaces of the compression component 43 with the rocker lever 11, the contact surfaces of the rocker lever 11 with the friction plate 45, and the contact surfaces of the friction plate 45 with the cap plate 46. This decreased compression force decreases the force required to move rocker lever 11, linkage bars 9, and the exercise motion components of machine 1 or machine 1A.

During operation of machine 1 or machine 1A, resistance mechanism 40 creates resistance as follows.

When the third left linkage bar 9 moves in a push direction, this causes rocker lever 11 to pivot in a first direction. Concurrently with this motion, the third right linkage bar 9 moves in a pull direction, this causes rocker lever 11 to pivot in a first direction. This first direction pivotal movement of rocker lever 11 causes the contact surfaces between the compression component 43 and the rocker lever 11 to create a coefficient of friction. This first direction pivotal movement of rocker lever 11 also causes the contact surfaces between the rocker lever 11 and friction disc 45 to create a coefficient of friction. This first direction pivotal movement of rocker lever 11 can also cause the contact surfaces between the friction disc 45 and the cap plate 46 to create a coefficient of friction. These combined coefficients of friction created by the first direction movements between the contact surfaces of compression component 43, rocker lever 11, friction disc 45, and the cap plate 46 during the first direction pivotal motion of rocker lever 11 creates a resistance to the first direction pivotal motion of rocker lever 11, the first direction motion of third linkage bars 9, and the first direction motion of the exercise motion components of machine 1 or machine 1A.

When the third left linkage bar 9 moves in a pull direction, this causes rocker lever 11 to pivot in a second direction. Concurrently with this motion, the third right linkage bar 9 moves in a push direction, this causes rocker lever 11 to pivot in a second direction. This second direction pivotal movement of rocker lever 11 causes the contact surfaces between the compression component 43 and the rocker lever 11 to create a coefficient of friction. This second direction pivotal movement of rocker lever 11 also causes the contact surfaces between the rocker lever 11 and friction disc 45 to create a coefficient of friction. This second direction pivotal movement of rocker lever 11 can also cause the contact surfaces between the friction disc 45 and the cap plate 46 to create a coefficient of friction. These combined coefficients of friction created by the second direction movements between the contact surfaces of compression component 43, rocker lever 11, friction disc 45, and the cap plate 46 during the second direction pivotal motion of rocker lever 11 creates a resistance to the second direction pivotal motion of rocker lever 11, the second direction motion of third linkage bars 9 and the second direction motion of the exercise motion components of machine 1 or machine 1A.

Now referring to FIGS. 20-25, FIGS. 20-25 are detailed drawings of the components, structures, and assemblies that create a second preferred embodiment of a climbing simulation exercise machine 1A. All of the components that comprise machine 1A are also comprised in machine 1 as previously described herein. However, some of the components of machine 1 have been eliminated from machine 1A such that machine 1A can create a similar function to machine 1 but at a lower cost. FIGS. 21-23 represent a machine 1A combined with a resistance mechanism 40. FIGS. 20, 24, and 25 represent a machine 1A with no resistance mechanism.

As illustrated in FIGS. 21-25, the stationary support structure 2 of machine 1A is identical to that of machine 1 with the exception that the section of stationary support structure 2 that supports pivot hub 13 on machine 1 has been eliminated on machine 1A. Left and right pivot hubs 13 have also been eliminated from machine 1A. Left and right connection flanges 35 have also been eliminated from machine 1A. Left and right connection bosses 35A have also been eliminated from machine 1A. Fourth Left and right linkage bars 10 have also been eliminated from machine 1A.

As best illustrated in FIGS. 21, 23, and 24, the functional difference between machine 1 and machine 1A is that the second ends of left and right handle levers 5 are rigidly connected proximal to a second ends of second left and right linkage bars 8. Handle levers 5 are therefore rigid to left and right linkages connection hubs 4 such that handle levers 5 pivot about linkages connection hubs 4.

FIG. 20 illustrates a close up isolated view of the structures and components that cooperate with third left and right linkage bars 9 and rocker lever 11 of machine 1A. In this view, rocker lever 11 is presented as transparent so as to more clearly illustrate the cooperative function of the third linkage bars 9 with rocker arm 11 of machine 1A without a resistance mechanism 40.

To operate machine 1A, a user U engages and operates machine 1A identically to the way user U operates machine 1 as previously described herein. User U can operate machine 1A with or without shin pads 24 as previously described herein.

During operation in a first direction motion of the left side components of machine 1A, when left pedal assembly 20 moves rearward along left wheel carriage track 3, this causes first left linkage bar 7 to move rearward and the second end of first left linkage bar 7 to pivot on the first end of second left linkage bar 8. This causes the first end of second left linkage bar 8 to swing rearward as the second end of second left linkage bar 8 pivots on left linkages connection hub 4. Concurrent to this motion the left handle lever 5 and left handle 6 pivot forward about left linkages connection hub 4 as left linkages connection hub rotates forward. This causes third left linkage bar 9 to move upward as the first end of third left linkage bar 9 pivots on left connection boss 36A and the second end of third left linkage bar 9 pivots on the left end of rocker lever 11. This causes the left end of rocker lever 11 to move upward as the center section of rocker lever 11 pivots about axle shaft 12.

During operation in a first direction motion of the right side components of machine 1A, when right pedal assembly 20 moves forward along right wheel carriage track 3, this causes first right linkage bar 7 to move forward and the second end of first right linkage bar 7 to pivot on the first end of second right linkage bar 8. This causes the first end of second right linkage bar 8 to swing forward as the second end of second right linkage bar 8 pivots on right linkages connection hub 4. Concurrent to this motion the right handle lever 5 and right handle 6 pivot rearward about right linkages connection hub 4 as right linkages connection hub rotates rearward. This causes third right linkage bar 9 to move downward as the first end of third right linkage bar 9 pivots on right connection boss 36A and the second end of third right linkage bar 9 pivots on the right end of rocker lever 11. This causes the right end of rocker lever 11 to move downward as the center section of rocker lever 11 pivots about axle shaft 12.

During operation of a second direction motion of the left and right side components of machine 1A, the motions are reversed from the first direction motion of the left and right side components of machine 1A as previously described herein. During the first or second direction motions of all embodiments of the invention, user U is in total control of the range of the exercise motions for all embodiments of the invention without having to making any adjustments to any of the features or components of any embodiment of the invention. In other words, user U can properly operate any embodiment of the invention by moving pedal assemblies 20 and handle levers 5 any distance in a forward or rearward motion simply by how far they choose to push or pull pedal assemblies 20 and arm levers 5. No components of any embodiments of the invention require the user U to move pedal assemblies 20 or arm levers 5 any preset distance to properly operate machine 1.

While the invention has been described in connection with certain preferred embodiments, it is not intended to limit the spirit or scope of the invention to the particular forms set forth, but is intended to cover such alternatives, modifications, and equivalents as may be included within the true spirit and scope of the invention as defined by the appending claims.
