Description

Exercise system for simulating outdoor terrain

technical field

The present disclosure generally relates to exercise equipment. More particularly, the present disclosure relates to exercise systems that include mechanisms that substantially simulate walking or running on outdoor terrain.

Background technique

In an attempt to improve their health and fitness, consumers are buying exercise devices in record numbers. A common challenge with exercise equipment is to motivate buyers to use the equipment on a consistent and ongoing basis. This lack of motivation may be a result of the repetitive nature of the exercises and exercise routines that a user may perform on a particular exercise device, as well as the variety of exercise devices.

Conventional treadmills allow the user to adjust various operating parameters to provide improved practice and variation during exercise. However, users are generally limited to treadmills whose operating parameters can be adjusted. For example, treadmills typically provide for adjustment of the incline and speed of the endless belt on which the user walks. This allows the user to walk, jog and/or run on the treadmill. This also allows the user to walk on horizontal or inclined surfaces. These adjustable operating parameters are often insufficient to motivate consumers to continue using the treadmill on an ongoing basis.

Some exercise devices have been developed to provide greater variety to exercises. For example, US Patent No. 6,152,854 discloses a treadmill that includes a movable user support having a plurality of rotatable members that rotate about an axis perpendicular to the direction of movement of the user support. Six cylinders forming a hexagon are attached to the base of the movable user support. The cylinder is attached to the base and ground by ball joints. The control of the cylinder allows movement in six degrees of freedom. Other exercise devices with adjustable parameters or that attempt to simulate outdoor terrain include US Patent No. 3,408,067, US Patent No. 4,423,864, US Patent No. 7,637,847, US Patent No. 8,029,415, and US Patent Publication No. 2009/0209393 .

Detailed ways

An illustration of an exemplary exercise system 10 is depicted in FIGS. 1-5 . One embodiment of exercise system 10 , shown as a treadmill, includes a console or control panel 12 having a display 14 and various inputs 16 . The control panel 12 is supported on a generally upright support structure 18 . The upright support structure 18 includes two side members 20 , 22 attached to a base frame 24 . A treadbase 26 is mounted on the base frame 24 and generally includes a pair of side rails 28, 30 each having a front portion near the upright support structure 18 and a distal portion away from the upright support structure 18. . The treadbase 26 also typically includes a front pulley 32 and a rear pulley 34 (FIG. 5) disposed between and supported by the side rails 28, 30, wherein a continuous belt 36 runs between the front pulley 32 and the rear pulley 34, respectively. Extends between and around the front pulley 32 and the rear pulley 34. Front pulley 32, rear pulley 34, and continuous belt 36 may each be considered movable elements that move during exercise performance. Deck 38 generally supports the upper run of belt 36 and an exercising individual on belt 36 .

As is common in electric treadmills, at least one of the front pulley 32 and the rear pulley 34 may be mechanically connected to an electric drive motor 40 by a drive belt 42 . The optional motor 40 is optionally electrically coupled to a controller 44 that controls the operation of the motor 40 and thus the speed of the belt 36 in response to various user inputs or other control signals.

In addition to the ability to control and vary the speed of belt 36, exercise system 10 also allows for varying degrees of incline or decline of treadbase 26 and belt 36 relative to base frame 24 or the floor or other support surface on which exercise system 10 rests. . To facilitate various inclines and declines of treadbase 26 , treadbase 26 is pivotally connected to base frame 24 by a ball joint connection assembly 70 ( FIG. 5 ). As shown in solid lines in FIG. 2, treadbase 26 may be oriented in an intermediate position. In the neutral position, treadbase 26 is substantially parallel to the support surface and generally aligned with base frame 24 . Treadbase 26 is rotatable about an X-axis of rotation, which is shown generally perpendicular to the longitudinal axis of treadbase 26 and passing through ball joint connection assembly 70 . As shown in FIG. 2 , treadbase 26 is rotatable about the X rotational axis between a neutral position (solid line) and a reclined position (dashed line). In the inclined position, the front end of the treadbase 26 is located above the neutral position. Similarly, treadbase 26 may be rotated about the X rotational axis to an inclined position in which the front end of treadbase 26 drops below the neutral position.

In the illustrated embodiment, exercise system 10 also allows treadbase 26 to roll side to side. As depicted in FIGS. 3 and 4 , treadbase 26 is rotatable about a Y rotational axis, which is shown generally orthogonal to the X rotational axis and parallel to the longitudinal axis of treadbase 26 . Treadbase 26 is rotatable about a Y rotational axis such that one side of treadbase 26 is higher than the other. For example, FIG. 3 shows treadbase 26 sloped so that side rail 28 is higher than side rail 30 . Similarly, FIG. 4 illustrates treadbase 26 being sloped so that side rail 30 is higher than side rail 28 . Accordingly, exercise system 10 provides surfaces that slope, decline, and/or side-to-side. In some embodiments, the treadbase 26 is also rotatable about a Z axis of rotation ( FIG. 1 ), which is shown generally orthogonal to both the X and Y axes of rotation. Rotation of treadbase 26 about any other axis may be resolved into a combination of rotations of treadbase 26 about the X, Y, Z axes of rotation.

As shown in FIG. 5 , exercise system 10 includes lift mechanisms 46 , 48 to adjust the incline, decline, and/or roll of treadbase 26 . The cross member 72 of the base frame 24 is generally in line with the lift mechanism 46 and extends between the rear end of the base frame 24 and the cross bar 52 . Cross member 74 of treadbase 26 is generally in line with lift mechanism 48 and extends between side rails 28 , 30 . In the illustrated embodiment, the cross member 74 extends across and above the cross member 72 such that the cross members 72 and 74 are generally perpendicular to each other. Lift members 46, 48 are shown as mechanical linear actuators, each of which includes a drive mechanism, gears, lead screws, and a lift motor housing. Upon receiving a control signal from the controller 44, the drive mechanism rotates the gear, which in turn rotates the lead screw. To raise the lift mechanism, the gear is rotated in a first direction, thereby extending the lead screw. To lower the lift mechanism, the gear is rotated in a second, opposite direction, causing the lead screw to retract. In some embodiments, the lift mechanism can tilt the treadbase about an X axis of rotation, tilt the treadbase about a Y axis of rotation, and/or rotate the treadbase about a Z axis of rotation.

In the illustrated embodiment, the lift mechanism 46 is generally in-line with the ball joint connection assembly 70 . Lift mechanism 46 is pivotally connected at the front end of treadbase 26 between crossbar 50 of treadbase 26 and crossbar 52 of base frame 24 . Lift mechanism 46 is positioned on crossbar 50 and crossbar 52 such that as lift mechanism 46 extends or retracts, treadbase 26 rotates about the X-rotation axis or tilts relative to the X-rotation axis. For example, lift mechanism 46 is located at a distance from the X-axis of rotation such that operation of lift mechanism 46 produces rotation of treadbase 26 about the X-axis of rotation. Furthermore, lift mechanism 46 is generally aligned with cross member 72 of base frame 24 and the Y axis of rotation such that operation of lift mechanism 46 does not produce rotation of treadbase 26 about the Y axis of rotation.

As shown in FIG. 6 , first end 54 of lift mechanism 46 is pivotally connected to crossbar 50 by bracket 58 , while second end 56 of lift mechanism 46 is connected to crossbar 52 by bracket 60 . Each of the brackets 58, 60 is generally V-shaped with a pin that can be secured between the two extending sides. First end 54 and second end 56 of lift mechanism 46 are pivotable on pins located within brackets 58 , 60 about an axis generally transverse to the longitudinal axis of treadbase 26 . The brackets 58, 60 are themselves pivotally connected to the crossbars 50, 52 by means of mechanical fasteners. For example, the bottom intersection of each of the brackets 58, 60 has a bolt extending therethrough and secured within a corresponding rail or frame of each bracket. This connection allows the bracket to rotate.

Referring now to FIG. 7 , lift mechanism 48 is similar to lift mechanism 46 . The lift mechanism is generally in line with the ball joint connection assembly 70 and is pivotally connected to the side rails 30 of the treadbase 26 and the base frame 24 . The lift mechanism 48 is positioned on the side rails 30 and the base frame 24 such that as the lift mechanism 48 is selectively extended or retracted, the treadbase 26 rotates about the Y rotational axis or tilts relative to the Y rotational axis. For example, lift mechanism 48 is located at a distance from the Y axis of rotation such that operation of lift mechanism 48 produces rotation of treadbase 26 about the Y axis of rotation. In addition, lift mechanism 48 is generally aligned with cross member 74 of treadbase 26 and the X axis of rotation extending through ball joint connection assembly 70 such that operation of lift mechanism 48 does not generate torque of treadbase 26 about the X axis of rotation. or rotate.

A first end 62 of the lift mechanism 48 is pivotally connected to the side rail 30 by a bracket 66 and a second end 64 of the lift mechanism 48 is connected to the base frame 24 by a bracket 68 . Each of the brackets 66 and 68 is generally U-shaped with a pin that can be secured between the two extending sides. The first end 62 and the second end 64 of the lift mechanism 48 are each mounted on pins of their respective brackets 66 , 68 . Brackets 66, 68 are pivotally connected to side rails 30 and base frame 24, respectively, by means of mechanical fasteners. For example, the bottom intersection of each of the brackets 66, 68 has a bolt extending therethrough and secured within a corresponding rail or frame of each bracket. This connection allows the bracket to rotate. As lift mechanism 48 raises or lowers the sides of treadbase 26 , first end 62 , second end 64 of lift mechanism 48 pivot on pins located within brackets 66 , 68 . In this manner, the first end 62 and the second end 64 of the lift mechanism 48 are able to pivot about an axis generally parallel to the longitudinal axis of the treadbase 26 .

In the illustrated embodiment, lift mechanisms 46, 48 may facilitate movement of treadbase 26 in a variety of different directions. More specifically, operation of lift mechanisms 46 , 48 in combination or independently may rotate treadbase 26 such that treadbase 26 tilts and/or rolls relative to base frame 24 . For example, when lift mechanism 46 is retracted to the retracted position, lift mechanism 46 tilts or rotates treadbase 26 about the X-axis of rotation to a tilted position in which the front end of treadbase 26 is positioned below the neutral position . When lift mechanism 46 is selectively extended to the extended position, lift mechanism 46 tilts or rotates treadbase 26 about the X-rotation axis to a tilted position in which the front end of treadbase 26 is positioned above the neutral position. Movement of the lift mechanism 46 to any position between the extended position and the retracted position may rotate the treadbase 26 about the X-rotation axis to a position between the incline position and the decline position.

As another example, when lift mechanism 48 is retracted to the retracted position, lift mechanism 48 rolls or rotates treadbase 26 about the Y axis of rotation to a first roll position wherein side rails 30 are moved below the side rails 30 The position of rail 28. When lift mechanism 48 is selectively extended to the extended position, lift mechanism 48 rolls or rotates treadbase 26 about the Y rotational axis to a second roll position in which side rail 28 is moved to a position higher than side rail 30 . Movement of the lift mechanism 48 to any position between the fully retracted position and the fully extended position may roll or rotate the treadbase 26 about the Y rotational axis to a position between the first roll position and the second roll position. Additionally, the combined operation of lift mechanism 46 and lift mechanism 48 may rotate treadbase 26 such that treadbase 26 rolls and tilts relative to base frame 24 . Thus, the lift mechanisms 46, 48 may rotate the treadbase 26 relative to the base frame 24 in a variety of different directions.

8A and 8B illustrate the ball joint connection assembly 70 . Ball joint connection assembly 70 includes a ball member 76 connected to cross member 72 and a ball socket 78 connected to cross member 74 . Ball joint connection assembly 70 pivotally connects cross member 74 and cross member 72 . The spherical member 76 is rotatably received in a recess 80 formed in the ball socket 78 and retained therein by a bearing shoulder 81 . As lift mechanisms 46 , 48 rotate treadbase 26 about the X and/or Y axes of rotation, treadbase 26 pivots on ball member 76 of ball joint connection assembly 70 . In this manner, treadbase 26 rotates about different axes extending through spherical member 76 such that treadbase 26 tilts, dips, and/or rolls relative to base frame 24 .

Attention is now turned to FIGS. 9 and 10 , which illustrate another embodiment of treadbase 126 and base frame 124 that may be used in conjunction with exercise system 10 in place of treadbase 26 and base frame 24 . Specifically, FIGS. 9 and 10 illustrate bottom and partial cross-sectional views of treadbase 126 and base frame 124 . As shown, the treadbase 126 is pivotally connected to the base frame 124 by a ball joint connection assembly 170 . Treadbase 126 includes a pair of generally parallel side rails 128 , 130 each having a front portion proximate to upright support structure 18 ( FIG. 1 ) and a distal portion distal from upright support structure 18 . The treadbase 126 also includes a front pulley 132 and a rear pulley 134 positioned between and supported by the side rails 128, 130, with a continuous belt 136 between the front pulley 132 and the rear pulley 134, respectively, and around the Front pulley 132 and rear pulley 134 extend. The deck 138 supports the upper run of the belt 136 . As with front pulley 32 and rear pulley 34 , at least one of front pulley 132 and rear pulley 134 may be mechanically connected to electric drive motor 40 .

The base frame 124 includes a cross bar 152 and a cross member 172 extending between the rear end of the base frame 124 and the cross bar 152 . The treadbase 126 includes a crossbar 150 and a cross member 174 extending between the side rails 128 , 130 . Cross member 174 is shown extending across cross member 172 and above cross member 172 such that cross members 172 and 174 are generally perpendicular to each other.

In the illustrated embodiment, the treadbase 126 and base frame 124 include two lift mechanisms 146 , 148 , shown as mechanical linear actuators, located at the forward end of the treadbase 126 . As explained in more detail below, lift mechanisms 146, 148 are connected to treadbase 126 and base frame 124 such that as lift mechanism 146 and/or lift mechanism 148 are extended or retracted, treadbase 126 tilts relative to base frame 124, tilt and/or turn.

Lift mechanism 146 is pivotally connected to crossbar 150 of treadbase 126 and crossbar 152 of base frame 124 . Lift mechanism 146 is also positioned between the Y axis of rotation and side rail 128 and is generally offset from ball joint connection assembly 170 , crossbar 172 , and Y axis of rotation toward side rail 128 . As noted above, lift mechanism 146 is positioned such that treadbase 126 may roll, tilt, and/or rotate relative to base frame 124 as lift mechanism 146 extends or retracts. For example, lift mechanism 146 is coupled between treadbase 126 and base frame 124 at a distance from the X, Y, and Z axes of rotation such that operation of lift mechanism 146 can cause treadbase 126 to rotate about the X, Y, and Z axes of rotation. Rotation of the Y axis of rotation and/or the Z axis of rotation.

As illustrated, first end 154 of lift mechanism 146 is pivotally connected to crossbar 150 by bracket 158 , while second end 156 of lift mechanism 146 is pivotally connected to crossbar 152 by bracket 160 . Each of the brackets 158, 160 is generally V-shaped with a pin that can be secured between the two extending sides. First end 154 and second end 156 of lift mechanism 146 are pivotable on pins within brackets 158 , 160 about an axis generally transverse to the longitudinal axis of treadbase 126 . Brackets 158 , 160 are pivotally connected to crossbars 150 , 152 . The brackets 158, 160 are pivotally connected to their crossbars or frames by mechanical fasteners. For example, the bottom intersection of each of the brackets 158, 160 may have a bolt extending therethrough and secured within a corresponding rail or frame of each bracket. Such a connection allows the frame to rotate about an axis generally parallel to the longitudinal axis of treadbase 126 .

Lift member 148 is pivotally connected to crossbar 150 and crossbar 152 of treadbase 126 . Lift mechanism 148 is also positioned between the Y axis of rotation and side rail 130 and is generally offset from ball joint connection assembly 170 , crossbar 172 , and Y axis of rotation toward side rail 130 . Like lift mechanism 146 , lift mechanism 148 is positioned such that treadbase 126 may roll, tilt, and/or rotate relative to base frame 124 as lift mechanism 148 extends or retracts. For example, lift mechanism 148 is coupled between treadbase 126 and base frame 124 at a distance from the X, Y, and Z axes of rotation such that operation of lift mechanism 148 can cause treadbase 126 to rotate about the X, Y, and Z axes of rotation. Rotation of the Y axis of rotation and/or the Z axis of rotation. First end 162 of lift mechanism 148 is pivotally connected to crossbar 150 by bracket 166 , and second end 164 of lift mechanism 148 is connected to crossbar 152 by bracket 168 . As shown, brackets 166 , 168 are similar to brackets 158 , 160 .

As described above, the control signals control operating parameters of exercise system 10 such as speed, incline, roll, and the like. In the illustrated embodiment, the lift mechanisms 146, 148 may facilitate movement of the treadbase 126 in a variety of different directions in response to control signals. More specifically, operation of the lift mechanisms 146 , 148 in combination or independently may move the treadbase 126 such that the treadbase 126 can tilt, tilt, roll, and/or rotate relative to the base frame 124 . For example, retraction of both lift mechanisms 146 , 148 to the retracted position rotates treadbase 126 about the X-rotation axis such that at least a portion of the front end of treadbase 126 is positioned below the rear end of treadbase 126 . When the lift mechanisms 146 , 148 are selectively extended to the extended position, the lift mechanisms 146 , 148 rotate the treadbase 126 about the X rotational axis such that at least a portion of the front end of the treadbase 126 is positioned over the rear end of the treadbase 126 . Additionally, retraction of lift mechanism 146 to the retracted position and/or extension of lift mechanism 148 rotates treadbase 126 about the Y rotational axis such that at least a portion of side rail 130 of treadbase 126 is positioned higher than side rail 128 . Additionally, extension of lift mechanism 146 to the extended position and/or retraction of lift mechanism 148 rotates treadbase 126 about the Y axis of rotation such that at least a portion of side rail 130 is positioned lower than side rail 128, as shown in FIG. .

As another example, extension of lift mechanism 146 to the extended position and retention of lift mechanism 148 in the neutral position rotates treadbase 126 about the Z rotational axis such that the front end of treadbase 126 turns toward side rail 130 . Extension of lift mechanism 148 to the extended position and retention of lift mechanism 146 in the neutral position rotates treadbase 126 about the Z rotational axis such that the rear end of treadbase 126 turns toward side rail 128 . Additionally, combined operation of lift mechanism 146 and lift mechanism 148 may rotate treadbase 126 such that treadbase 126 simultaneously tilts, tilts/declines, and/or rotates relative to base frame 124 . Thus, the lift mechanisms 146 , 148 may rotate the treadbase 126 relative to the base frame 124 in a variety of different directions.

Similar to ball joint connection assembly 70 , ball joint connection assembly 170 includes a ball member 176 connected to cross member 172 and a ball socket 178 connected to cross member 174 .

Industrial applicability

Embodiments of the present disclosure generally relate to exercise systems that incline, decline, and/or side-to-side to provide variation in exercise. The exercise system can be any type of exercise system such as a treadmill, exercise bike, Nordic style ski exercise system, rowing machine, stair stepper, walking machine, climbing machine, elliptical or stride exercise system. The incline, decline, and roll functionality of the disclosed exercise system allows the exercise system to simulate outdoor terrain or otherwise alter the operation of the exercise system. For example, a treadmill may have two or more lift mechanisms that rotate the treadbase about two or more axes of rotation to simulate going down a hill, up a hill, and/or across a canyon wall or river bank .

Although exercise equipment includes incline and decline mechanisms, these generally do not adequately simulate outdoor terrain or sufficiently motivate the user. For example, to simulate canyon running, these mechanisms allow a user to walk on a level surface or an inclined surface. These mechanisms, however, do not allow the user to walk on slopes, declines, and side slopes or slopes like conventional canyon trails.

In general, the structures of the present exemplary disclosure provide an exercise system that substantially simulates outdoor terrain in response to one or more control signals. For example, the treadbase may be pivotally connected to the base frame by a ball joint connection assembly. One or more lift or tilt mechanisms connected between the base frame and the treadbase may cause the treadbase to rotate relative to the base frame and through the ball joint connection assembly. Accordingly, the treadbase may be rotated in various directions relative to the base frame to approximately simulate outdoor terrain. That is, one or more lift or tilt mechanisms may be operable to selectively rotate the treadbase about the ball joint connection assembly to tilt, decline, and/or roll the treadbase.

The ball joint connection assembly allows the treadbase to rotate about an infinite number of axes of rotation extending through the ball joint connection assembly. In some configurations, the one or more axes of rotation may be centrally located relative to the treadbase. For example, one axis of rotation may be centered between the side rails of the treadbase. In other configurations, one or more axes of rotation may be offset relative to the center of the treadbase. For example, one axis of rotation may be offset such that the axis of rotation is closer to one side rail or the other side rail of the treadbase.

Additionally, according to some configurations, the ball joint connection assembly may be a ball joint including a ball member and a ball socket connected to the treadbase or base frame. For example, a ball member can be connected to the treadbase and a ball socket can be connected to the base frame. The ball joint connection assembly may be centered relative to the treadbase. In other configurations, the ball joint connection assembly may be offset relative to the center of the treadbase. For example, the ball joint connection assembly may be offset such that the ball joint connection assembly is closer to the front end than the rear end of the treadbase. In some configurations, the ball joint connection assembly may be a universal joint, saddle joint, pivoting rocker, or other suitable type of connection assembly. Additionally, the ball joint connection assembly allows the treadbase to rotate about multiple axes of rotation relative to the base frame. In this manner, the treadbase can simulate outdoor terrain by incline, decline, roll and/or rotate relative to the base frame.

The pivotal connection between the lift/roll mechanism and the base frame and/or treadbase allows the treadbase to roll, tilt, or decline without bending, overextending, or otherwise damaging the lift/roll mechanism. Additionally, in some configurations, the treadbase includes features for controlling torsion of the treadbase. For example, the treadbase may have a specific stiffness, size, and/or system of counterweights to resist torsion of the treadbase.

In some configurations, the exercise system includes two, three, four, five, or any suitable number of lift mechanisms with or without ball joint connection assemblies. For example, an exercise system may include two lift mechanisms connected to the front end of the treadbase and a third lift mechanism connected to the side rails of the treadbase. Lifting mechanisms can be linear actuators, rotary actuators, multi-turn actuators, quarter-turn actuators, lever actuators, mechanical actuators, pneumatic actuators, electric actuators, hydraulic actuators device, ball screw mechanism or a combination thereof.

The lift mechanism may be connected to any portion of the base frame and/or treadbase by any suitable connection. For example, the lifting mechanism may be connected to the base frame and/or treadbase by a ball joint, foot joint, pin connection, hinge, bracket, or other suitable connection type. Additionally, a lift mechanism may be attached to the sides, front, top and/or bottom of the base frame and/or treadbase.

Operation of the lift/tilt mechanism moves the treadbase about different axes of rotation to simulate outdoor terrain. For example, in one configuration, extension of the first lift mechanism and extension of the second lift mechanism may rotate the treadbase about the first axis of rotation to tilt the treadbase. Also, retraction of the first lift mechanism and retraction of the second lift mechanism may rotate the treadbase about the first axis of rotation to tilt the treadbase. Additionally, extension or retraction of the first lift mechanism and retraction or extension of the second lift mechanism may rotate the treadbase about the second axis of rotation to roll the treadbase to one side or the other. Additionally, various combinations of extension and retraction may be used to rotate the treadbase about both the first and second axes of rotation to tilt/decline the treadbase and tilt the treadbase sideways.

Optionally, the exercise system may include a deck assembly that is rotatable relative to the treadbase. In some configurations, the deck assembly may be pivotally connected to the treadbase by one or more pivotal or hinged connections. In one configuration, the hinged connection may be any suitable type of hinge. For example, the hinged connection may be a continuous hinge, a butt hinge, a butterfly hinge, a leaf hinge, a barrel hinge. In some embodiments, the deck assembly may be pivotally connected to the treadbase via lift mechanisms located on opposing side members of the deck assembly.

Accordingly, one or more lift mechanisms may be connected between the base frame and the treadbase and/or between one or more treadbase side rails and the deck assembly. One or more lift mechanisms may be used to tilt, tilt, and/or tilt the treadbase relative to the base frame. The one or more lift mechanisms may also be used to tilt, dip, and/or tilt the deck assembly relative to the treadbase to generally simulate outdoor terrain.
