DETAILED DESCRIPTION

In the following description, specific details of various embodiments are provided. However, some embodiments may be practiced with less than all of these specific details. In other instances, certain methods, procedures, components, structures, and/or functions are described in no more detail than to enable the various embodiments of the invention, for the sake of brevity and clarity.

While many embodiments are described herein, at least some of the described embodiments provide a system for a treadmill with a flexible deck.

FIG. 1 depicts a perspective view of one embodiment of a treadmill 100 with a flexible deck 104. The treadmill 100 includes a belt 102 and a flexible deck 104. The treadmill 100 causes the belt 102 to move continuously to provide a walking surface for a user. In an alternate embodiment, the belt 102 moves in response to forces supplied by a user walking on the treadmill 100.

The belt 102, in certain embodiments, is a continuous belt. The belt may travel over one or more elements of the treadmill 100, such as rollers (not shown). The belt may include any material known in the art, including, but not limited to, synthetic rubber.

In some embodiments, the flexible deck 104 is disposed within the belt 102 and provides a support surface to a user striding on the treadmill 100. The flexible deck 104 may include one or more components configured to provide or manage flex in the flexible deck 104. The flexible deck 104 is described in greater detail in relation to FIGS. 2-7 below.

FIG. 2 depicts an exploded perspective view of one embodiment of the treadmill of FIG. 1. The treadmill 100 includes the flexible deck 104, a frame 202, one or more suspension connectors 204, and one or more intermediate supports 206. The treadmill 100 provides managed response of the flexible deck for users of the treadmill 100.

The frame 202, in some embodiments, provides support and attachment points for other components of the treadmill 100. The frame 202 may include any material capable of providing the stiffness and strength necessary for the other components of the treadmill 100 to perform the requisite functions. In one embodiment, the frame 202 includes a metal, such as steel.

The suspension connector 204, in one embodiment, is disposed between the flexible deck 104 and the frame 202. The suspension connector 204 provides a connection between the flexible deck 104 and the frame 202 that facilitates flex of the flexible deck 104. The suspension connector 204 may provide rotation of at least a portion of the flexible deck 104 relative to the frame 202 around one or more axes. In some embodiments, the suspension connector 204 allows for translation of at least a portion of the flexible deck 104 relative to the frame 202 in one or more directions.

In one embodiment, the treadmill 100 includes four suspension connectors 204. The suspension connectors 204 may be disposed at or near four corners of the flexible deck 104. Embodiments of the suspension connector 204 are described in greater detail below.

The one or more intermediate supports 206, in some embodiments, are each disposed between the frame 202 and the flexible deck 104. In some embodiments, the treadmill 100 includes an intermediate support 206 on each of two opposing sides of the frame 202. In one embodiment, the treadmill 100 includes more than one intermediate support 206 on each of two opposing sides of the frame 202.

Each intermediate support 206 manages movement of a portion of the flexible deck 104. In one embodiment, the intermediate support 206 progressively resists flexion of the flexible deck 104 in response to an applied force on the flexible deck 104, such as the weight of a user standing or striding on the flexible deck 104. In certain embodiments, the intermediate support 206 dampens movement of the flexible deck 104.

The intermediate support 206 may include any material capable of performing the functions of the intermediate support 206. For example, the intermediate support 206 may include a polymer material. In one example, the intermediate support 206 includes polyurethane.

In certain embodiments, the response of the intermediate support 206 is adjustable. For example, the intermediate support 206 may be adjustable to increase or decrease a spring constant of the intermediate support 206. In other words, a stiffness of the intermediate support 206 may be adjusted. In another embodiment, a position of the intermediate support 206 may be adjustable relative to the flexible deck 104. In some embodiments, the intermediate support 206 may be adjustable such that it moves closer to or further away from the flexible deck 104. In one embodiment, the intermediate support may be adjustable such that it moves closer to or further away from a suspension connector 204. In some embodiments, the intermediate support 206 dampens movement of the flexible deck 104.

For example, it may be useful to tune the intermediate support 206 to correspond to a weight of a user. The intermediate support 206 may be stiffened for a user with a relatively high weight, and the stiffness of the intermediate support 206 may be reduced for a user with a relatively low weight.

In some embodiments, adjustment of the stiffness of the intermediate support 206 may be manual. A user may add or remove components of the treadmill 100, may adjust the position of one or more components, or take other actions to modify the stiffness of the intermediate support 206. An example of a manually adjustable intermediate support 206 is described below in relation to FIG. 7.

In another embodiment, adjustment of the stiffness or location of the intermediate support 206 may be automated. For example, the treadmill 100 may adjust the interaction of the intermediate support 206 with the flexible deck 104 in response to determining a weight of a user. In one example, the treadmill 100 may adjust a position of the intermediate support 206 relative to other components of the treadmill 100. In another example, one or more components of the intermediate support 206 may be moved in response to determining a user's weight. In yet another example, the intermediate support 206 includes a fluid spring or fluid damper, such as a hydraulic shock or an air spring, and a fluid, such as air, water, or oil, may be pumped into or out of the intermediate support 206 in response to a determination of a user's weight. In a different embodiment, the response of the intermediate support 206 is selectively modified by an electromagnet (not shown), such as in a magnetorheological damper. In another embodiment, an electromagnetic actuator (not shown) adjusts a position of the intermediate support 206 relative to other components of the treadmill 100. The electromagnetic actuator may apply a force to the intermediate support 206 to adjust the position of the intermediate support 206.

FIG. 3 depicts an exploded perspective view of one embodiment of the flexible deck 104 of FIG. 1. The flexible deck 104 includes a flexible component 302 and a wear surface 304. The flexible deck 104 flexes in response to a force applied by a user striding on the treadmill 100.

The flexible component 302 includes a flexible material that, when supported at opposite ends of the flexible component 302, flexes in response to a force provided by a user striding on the treadmill 100. The flexible component 302 may include any materials that provided a desired flexibility, strength, and weight for the flexible deck 104. For example, the flexible component 302 may include a sheet of aluminum. In an alternative example, the flexible component 302 may include a polymer. In another example, the flexible component 302 may include a composite material, such as carbon fiber or fiberglass in a polymer matrix.

In one embodiment, the flexible component 302 includes a metal panel. The metal panel may extend substantially the entire width and length of the flexible deck 104. In certain embodiments, the flexible deck 104 includes a heat transfer surface 312 to transfer heat from the belt 102 to the metal panel. The metal panel may conduct heat away from the belt 102 and radiate excess heat to the surrounding air. This may reduce the average temperature of the belt 102 relative to the temperature of a treadmill without a metal panel and a heat transfer surface 312.

In some embodiments, the flexible deck 104 includes a wear surface 304. The wear surface 304 may resist wear of the flexible deck 104 as the treadmill 100 is operated. In some embodiments, the wear surface 304 is replaceable. In certain embodiments, the wear surface 304 exhibits a relatively low friction as the belt 102 travels over the wear surface 304. For example, the wear surface 304 may include a phenolic sheet.

In an alternate embodiment, the flexible component 302 includes a surface treatment that acts as the wear surface 304. For example, the flexible component 302 may be aluminum, and one or more surfaces of the aluminum may be anodized to form a wear surface 304.

In certain embodiments, the flexible deck 104 is connected to the suspension connector 204. The flexible deck 104 may be connected to the suspension connector 204 using one or more deck fasteners 306. In some embodiments, the one or more deck fasteners 306 may interact with one or more deck fastener plates 308 to secure the flexible component 302 to the suspension connector 204. In some embodiments, the one or more deck fasteners 306 may interact with one or more deck fastener plates 308 to secure the wear surface 304 to the suspension connector 204.

The suspension connector 204 may include a suspension pivot 310. The suspension pivot 310 may be connected to the frame 102. In one embodiment, a portion of the flexible deck 104 pivots around the suspension pivot 310 in response to an applied load on the flexible deck 104.

FIG. 4 depicts a front cross-sectional view of one embodiment of the flexible deck 104 of FIG. 1. The flexible deck 104 includes a flexible component 302 and a wear surface 304. In some embodiments, the flexible deck 104 is connected to a suspension connector 204. The flexible component 302, the wear surface 304, and the suspension connector 204 may be similar to like-numbered components described above. The flexible deck 104 flexes in response to a force applied by a user striding on the treadmill 100.

In some embodiments, the flexible deck 104 is connected to the suspension connector 204 using a deck fastener 306. The deck fastener 306 may be configured to cooperate with a deck fastener plate 308 to secure one or more components of the flexible deck 104 to the suspension connector 204.

In one embodiment, the suspension connector 204 includes a suspension bushing 402. The suspension bushing 402 may be configured to deform under an applied force. In some embodiments, the suspension bushing 402 allows for one or more of rotation and translation of the flexible deck 104 relative to other components of the treadmill 100. In one embodiment, the suspension bushing 402 allows a portion of the flexible deck 104 near the deck fastener 306 to rotate around a suspension pivot 310 under a load applied by a user striding on the treadmill 100.

The suspension bushing 402 may include any material capable of performing the functions of the suspension bushing 402. For example, the suspension bushing 402 may include a polymer material. In one example, the suspension bushing 402 includes polyurethane.

FIG. 5 depicts a side cross-sectional view of one embodiment of the treadmill 100 of FIG. 1. The treadmill 100 includes a flexible deck 104, one or more suspension connectors 204, and one or more intermediate supports 206. The flexible deck 104, the one or more suspension connectors 204, and the one or more intermediate supports 206 may be similar to like-numbered components described above. The treadmill 100 provides a striding surface with a managed flex response.

In one embodiment, the treadmill 100 includes four suspension connectors 204. The flexible deck 104 may be substantially rectangular and a suspension connector 204 may be disposed at or near each corner of the rectangular flexible deck 104. The suspension connectors 204 may connect the flexible deck 104 to other components of the treadmill 100. In some embodiments, the suspension connectors 204 deform under a force applied by a user striding on the treadmill 100 to manage a flex response of the flexible deck 104.

The treadmill 100, in some embodiments, includes two intermediate supports 206. The flexible deck 104 may be substantially rectangular and an intermediate support 206 may be disposed between two suspension connectors 204 at or near a left and right side of the rectangular flexible deck 104. The intermediate supports 206 may support the flexible deck 104 relative to other components of the treadmill 100. In some embodiments, the intermediate supports 206 deform under a force applied by a user striding on the treadmill 100 to manage a flex response of the flexible deck 104. In one embodiment, the stiffness of the intermediate supports 206 are adjustable.

FIGS. 6A-6C depict side views of one embodiment of the flexible deck 104 of FIG. 1 under no applied force, a moderate applied force 602, and a high applied force 604, respectively. The flexible deck 104 is connected to the treadmill 100 via a plurality of suspension connectors 204. The flexible deck 104 is configured to flex under an applied force.

In one embodiment, the flexible deck 104 is substantially rectangular and a suspension connector 204 is disposed at each of a first end 606 and a second end 608 of the flexible deck 104. The suspension connectors 204 are configured to rotate around a suspension pivot 310 in response to an applied load. In FIG. 6B, a moderate applied load 602, such as that caused by a relatively low-weight user striding on the treadmill 100, causes moderate flexion of the flexible deck 104. At or near the first end 606, the flexible deck 104 pivots around the suspension pivot 310 in response to the moderate applied force 602. At or near the second end 608, the flexible deck 104 pivots in an opposite direction around a suspension pivot 310 in response to the moderate applied force 602. In response to a relatively high applied force 604, flexion and pivoting of the deck is relatively higher than that caused in response to the moderate applied force 602.

The intermediate support 206, in some embodiments, supports the flexible deck 104 and resists flexion of the flexible deck 104. In response to the moderate applied force 602, the intermediate support 206 deforms and applies a reaction force to counter the intermediate force 602. In response to a relatively high applied force 604, deformation of the intermediate support 206 and the resulting reaction force are relatively higher.

FIG. 7 depicts a perspective view of one embodiment of the flexible deck 104 of FIG. 1 with a stiffener 702. In one embodiment, the stiffener 702 is a component that can be added to the intermediate support 206. For example, the stiffener 702 may be polyurethane component than can be inserted into the intermediate support 206 to change the response of the intermediate support 206 to an applied force.

The stiffener 702 may be configured to be manually added to the treadmill 100 by a user. In another embodiment, the stiffener 702 may be automatically applied in response to a user input or a determination by the treadmill that a user exceeds a predetermined weight.

FIG. 8 depicts an exploded perspective view of one embodiment of a treadmill 800 with a flexible deck 802. The treadmill 800 includes the flexible deck 802, a frame 801, one or more suspension connectors 804, and one or more intermediate supports 806. The treadmill 800 provides managed foot impact for users of the treadmill 800.

The frame 801, in some embodiments, provides support and attachment points for other components of the treadmill 800. The frame 801 may include any material capable of providing the stiffness and strength necessary for the other components of the treadmill 800 to perform the requisite functions. In one embodiment, the frame 801 includes steel.

The suspension connector 804, in one embodiment, is disposed between the flexible deck 802 and the frame 801. The suspension connector 804 provides a connection between the flexible deck 802 and the frame 801 that manages flex of the flexible deck 802. The suspension connector 804 may allow rotation of at least a portion of the flexible deck 802 relative to the frame 801 around one or more axes. In some embodiments, the suspension connector 804 allows for translation of at least a portion of the flexible deck 802 relative to the frame 801 in one or more directions.

In one embodiment, the treadmill 800 includes four suspension connectors 804. The suspension connectors 804 may be disposed at or near four corners of the flexible deck 802. Embodiments of the suspension connector 804 are described in greater detail below.

The intermediate support 806, in some embodiments, is disposed between the frame 801 and the flexible deck 802. The intermediate support 806 manages movement of a portion of the flexible deck 802. In one embodiment, the intermediate support 806 progressively resists flexion of the flexible deck 802 in response to an applied force on the flexible deck 802, such as the weight of a user standing or striding on the treadmill 800. In certain embodiments, the intermediate support 806 dampens movement of the flexible deck 802.

The intermediate support 806 may include any material capable of performing the functions of the intermediate support 806. For example, the intermediate support 806 may include a polymer material. In one example, the intermediate support 806 includes polyurethane.

In certain embodiments, the response of the intermediate support 806 is adjustable. For example, the intermediate support 806 may be adjustable to increase or decrease a spring constant of the intermediate support 806. In other words, a stiffness of the intermediate support 806 may be adjusted. In some embodiments, the response of the intermediate support 806 may be adjusted to change how the intermediate support 806 dampens movement of the flexible deck 802.

For example, it may be useful to tune the intermediate support 806 to correspond to a weight of a user. The intermediate support 806 may be stiffened for a user with a relatively high weight, and the stiffness of the intermediate support 806 may be reduced for a user with a relatively low weight.

In some embodiments, adjustment of the stiffness of the intermediate support 806 may be manual. A user may add or remove components of the treadmill 800, may adjust the position of one or more components, or take other actions to modify the stiffness of the intermediate support 806.

In another embodiment, adjustment of the stiffness of the intermediate support 806 may be automated. For example, the treadmill 800 may adjust the interaction of the intermediate support 806 with the flexible deck 802 in response to determining a weight of a user. In one example, the treadmill 800 may adjust a position of the intermediate support 806 relative to other components of the treadmill 800. In another example, one or more components of the intermediate support 806 may be moved in response to determining a user's weight. In yet another example, the intermediate support 806 includes a fluid spring or fluid damper, such as a hydraulic shock or an air spring, and a fluid, such as air, water, or oil, may be pumped into or out of the intermediate support 806 in response to a determination of a user's weight. In a different embodiment, the response of the intermediate support 806 is modified by an electromagnet (not shown), such as in a magnetorheological damper. In another embodiment, an electromagnetic actuator (not shown) adjusts a position of the intermediate support 806 relative to other components of the treadmill 800. The electromagnetic actuator may apply a force to the intermediate support 806 to adjust the position of the intermediate support 806.

FIG. 9 depicts an exploded perspective view of one embodiment of the flexible deck 802 of FIG. 8. The flexible deck 802 includes a flexible component 902 and a wear surface 904. The flexible deck 802 flexes in response to a force applied by a user striding on the treadmill 800.

The flexible component 902 includes a flexible material that, when supported at it opposite ends of the flexible component 902, flexes in response to a force provided by a user striding on the treadmill 800. The flexible component 902 may include any materials that provided a desired flexibility, strength, and weight for the flexible deck 802. For example, the flexible component 902 may include a sheet of aluminum. In an alternative example, the flexible component 902 may include a polymer. In another example, the flexible component 902 may include a composite material, such as carbon fiber or fiberglass in a polymer matrix.

In some embodiments, the flexible deck 802 includes a wear surface 904. The wear surface 904 may resist wear of the flexible deck 802 as the treadmill 800 is operated. In some embodiments, the wear surface 904 is replaceable. In certain embodiments, the wear surface 904 exhibits a relatively low friction as the belt 102 travels over the wear surface 904.

In an alternate embodiment, the flexible component 902 includes a surface treatment that acts as the wear surface 904. For example, the flexible component 902 may be aluminum, and one or more surfaces of the aluminum may be anodized to form a wear surface 904.

In certain embodiments, the flexible deck 802 is connected to the suspension connector 804. The flexible deck 802 may be connected to the suspension connector 804 using one or more deck fasteners 906. In some embodiments, the one or more deck fasteners 906 may interact with one or more deck fastener plates 908 to secure the flexible component 902 to the suspension connector 804. In some embodiments, the one or more deck fasteners 906 may interact with one or more deck fastener plates 908 to secure the wear surface 904 to the suspension connector 804.

The suspension connector 804 may include one or more suspension fasteners 910. The one or more suspension fasteners 910 may secure the suspension connector 804 to the frame 801.

FIG. 10 depicts an exploded perspective view of one embodiment of the suspension connector 804 of FIG. 8. The suspension connector 804 includes a suspension pivot 1002, a suspension pivot bracket 1004, a suspension element 1006, and a suspension mounting block 1008. The suspension connector 804 connects the flexible deck 802 to the frame 801 and contributes to management of flexion of the flexible deck 802.

The suspension pivot 1002, in one embodiment, allows rotation of a connected component around an axis of the suspension pivot 1002 and restricts rotation around other axes or translation of the connected components. In the illustrated embodiment, the suspension pivot 1002 allows rotation of the suspension pivot bracket 1004 relative to the suspension element 1006.

In some embodiments, the suspension pivot bracket 1004 is connected to the flexible deck 802 by one or more deck fasteners 906. In some embodiments, the deck fasteners 906 cooperate with a deck fastener plate 908 to secure one or more elements of the flexible deck 802 to the suspension pivot bracket 1004. An interaction between the suspension pivot bracket 1004 and the suspension pivot 1002 may allow at least a portion of the attached flexible deck 802 to rotate around the suspension pivot 1002 in response to a load applied to the flexible deck 802, such as that applied by a user striding on the treadmill 800.

The suspension pivot 1002 may be rotatably connected to the suspension bracket 1004 and the suspension element 1006. The suspension element 1006 may be configured to deform under an applied force. In some embodiments, the suspension element 1006 allows for one or more of rotation and translation of the flexible deck 802 relative to other components of the treadmill 800. In one embodiment, the suspension element 1006 allows a portion of the flexible deck 802 near the suspension pivot bracket 1004 to rotate around the suspension pivot 1002 under a load applied by a user striding on the treadmill 800.

The suspension element 1006 may include any material capable of performing the functions of the suspension element 1006. For example, the suspension element 1006 may include a polymer material. In one example, the suspension element 1006 includes polyurethane.

In one embodiment, suspension mounting block 1008 is attached to the suspension element 1006 and the frame 801. The suspension mounting block 1008 may be attached to other components using fasteners, formed keyways, or a combination of these. In one embodiment, the suspension mounting block 1008 is a relatively stiff and strong material, such as steel or aluminum.

FIG. 11 depicts a side cross-sectional view of one embodiment of the treadmill 800 of FIG. 8. The treadmill 800 includes a flexible deck 802, one or more suspension connectors 804, and one or more intermediate supports 806. The flexible deck 802, the one or more suspension connectors 804, and the one or more intermediate supports 806 may be similar to like-numbered components described above. The treadmill 800 provides a striding surface with a managed flex response.

In one embodiment, the treadmill 800 includes four suspension connectors 804. The flexible deck 802 may be substantially rectangular and a suspension connector 804 may be disposed at or near each corner of the rectangular flexible deck 802. The suspension connectors 804 may connect the flexible deck 802 to other components of the treadmill 800. In some embodiments, the suspension connectors 804 deform under a force applied by a user striding on the treadmill 800 to manage a flex response of the flexible deck 802.

The treadmill 800, in some embodiments, includes two intermediate supports 806. The flexible deck 802 may be substantially rectangular and an intermediate support 806 may be disposed between two suspension connectors 804 at or near a side of the rectangular flexible deck 802. In some embodiments, the treadmill 800 includes two intermediate supports 806, one disposed under a right side of the flexible deck 802 and the other disposed under a left side of the flexible deck 802. The intermediate supports 806 may support the flexible deck 802 relative to other components of the treadmill 800. In some embodiments, the intermediate supports 806 deform under a force applied by a user striding on the treadmill 800 to manage a flex response of the flexible deck 802. In one embodiment, the stiffness of the intermediate supports 806 is adjustable.

FIG. 12A-12C depict side views of one embodiment of the flexible deck 802 of FIG. 8 under no applied force, a moderate applied force 1202, and a high applied force 1204, respectively. The flexible deck 802 is connected to the treadmill 800 via a plurality of suspension connectors 804. The flexible deck 802 is configured to flex under an applied force.

In one embodiment, the flexible deck 802 is substantially rectangular and a suspension connector 804 is disposed at each of a first end 1206 and a second end 1208 of the flexible deck 802. The suspension connectors 804 are configured to rotate around a suspension pivot 1002 in response to an applied load. In FIG. 12B, a moderate applied load 1202, such as that caused by a relatively low-weight user striding on the treadmill 800, causes moderate flexion of the flexible deck 802. At or near the first end 1206, the flexible deck 802 pivots around the suspension pivot 1002 in response to the moderate applied force 1202. At or near the second end 1208, the flexible deck 802 pivots in an opposite direction around a suspension pivot 1002 in response to the moderate applied force 1202. In response to a relatively high applied force 1204, flexion and pivoting of the deck is relatively higher than that caused in response to the moderate applied force 1202.

The intermediate support 806, in some embodiments, supports the flexible deck 802 and resists flexion of the flexible deck 802. In response to the moderate applied force 1202, the intermediate support 806 deforms and applies a reaction force to counter the intermediate force 1202. In response to a relatively high applied force 1204, deformation of the intermediate support 806 and the resulting reaction force are relatively higher.

FIG. 13 is a flowchart diagram depicting one embodiment of a method 1300 for manufacturing treadmill 100 with a flexible deck 104. The method 1300 is in certain embodiments a method of use or manufacture of the system and apparatus of FIGS. 1-12, and will be discussed with reference to those figures. Nevertheless, the method 1300 may also be conducted independently thereof and is not intended to be limited specifically to the specific embodiments discussed above with respect to those figures.

As shown in FIG. 13, a frame 202 is provided 1302. The frame may provide connection points and support for other elements of the treadmill 100. In certain embodiments, a suspension connector 204 is provided 1304. The suspension connector 204 may include components configured to deform under an applied load.

A flexible deck 104 is attached 1306 to the frame 102 via the suspension connector 204 in some embodiments. The flexible deck 104 may be attached to the suspension connector 204 and the suspension connector 204 may be attached to the frame 102. The suspension connector 204 may allow and manage flexion of the flexible deck 104 in response to loads caused by users of the treadmill 100 striding on the treadmill 100.

In some embodiments, an intermediate support 206 is disposed 1308 between the flexible deck 104 and the frame 102.
