Definitions

  • the typical treadmill comprises a continuous belt, or tread, whic is wrapped around a pair of rollers and driven by a motor.
  • T treadmill user must walk or run on the belt at a rate which matches the belt speed to remain stationary relative to the device.
  • the treadmill permits the user to simulate walking o running in an indoor environment.
  • Exercise treadmills are found in a variety of applications. For example, treadmills frequently see service as a medical diagnostic tool, as a physical fitness device and/or as a therapeutic apparatus. In each of these applications, the treadmill is subjected to the repeated footfalls of its users. It is estimated that a treadmill machine in daily use must withstand tens of millions of footfalls a year. The shock of these impacts is not insignificant and accelerates wear of treadmill components. a result, mean time between failure and overall treadmill lif are negatively affected. Wear of treadmill components caused by frequent operation and repeated footfalls necessitates implementation of a maintenance schedule. Construction of th typical treadmill device makes access to serviceable componen such as rollers, drive belts, the tread and platform difficul Repair, replacement and lubrication of these parts thus entai a significant amount of labor and cost.
  • serviceable componen such as rollers, drive belts, the tread and platform difficul Repair, replacement and lubrication of these parts thus entai a significant amount of labor and cost.
  • the impact of the user with the treadmill not only causes treadmill wear, but also presents a potential source o injury for the user. Foot, leg, joint and back problems are types of potential injury. These injuries can result from th reaction forces and vibrations of the treadmill on the user.
  • SUMMARY OF THE INVENTION The present invention increases treadmill durabilityit and mean time between failure while improving user safety and reducing the risk of injury.
  • the present invention also improves treadmill life and user safety by its unique construction which provides easy access to serviceable components.
  • the treadmill of the present invention provides a suspension system for the platform over which the tread passes
  • Previous devices used a platform which either was not suspende or was only partially suspended, for example, by being pivotally suspended or cantilevered.
  • the platform is fully suspended.
  • fully suspended it is meant that the plane of the platform can be tilted in any direction from its rest position.
  • a platform constrained to pivot about an axis is not fully suspended since it cannot tilt in a direction at an angle to such axis.
  • the suspension means will tend to restore the platform thus tilted back to its rest position.
  • three or, preferably, four, independent suspension devices are used to suspend the platform.
  • the platform is suspended with respect to the frame of the treadmill system.
  • the suspension system includes a set of air springs which absorb the shock of the user's footfalls.
  • This suspension system not only reduces the risk o leg, back and joint injury caused by repeated footfalls, but also makes the machine more pleasurable to use thereby extending the exercise, diagnostic and therapeutic benefits to more users.
  • the suspension system also reduces the dynamic loading on the treadmill apparatus and components thereby improving system reliability and life.
  • the suspension system of the current invention has the further advantage of improved performance over treadmills incorporating steel coil springs or certain other shock absorption devices to partially damp the impact of the user's motion. Air springs damp out more of this impact force.
  • the nonlinear load response of the air springs also means that the suspension system of the present invention provides shock absorption benefits over a wider range of user size, weight, strength and ability than certain other suspension systems.
  • the treadmill right sidepiece is readily removable. This feature allows easy access to the air springs and to oth serviceable components. Treadmill maintenance is therefore less costly and more trouble free. Less onerous maintenance also yields improvements in treadmill life and safety since proper maintenance is more likely to occur. Removal of right sidepiece and servicing is facilitated by using the quick disconnect coupling which elevates the right side of the machine.

  • frame 19 is constructed from aluminum.
  • the light weight of aluminum makes it an advantageous material for construction of a treadmill; especially treadmill models which must be partially tilted to simulate an incline.

  • frame 19 may be fabricated from steel. Steel is less expensive and easier to weld than aluminum.
  • Frame 19 can, however, be constructed from a variety of other materials but, such a material should preferably be lightweight, inexpensive, durable, act as a heat sink for electronics, and possess good fatigue and corrosion resistance. Once fabricated, frame 19 may be painted or covered, e.g. with a plastic wall.

  • ply 12c Other possible materials with which to fabricate ply 12c include polyethylene, Teflon", Formica”” bonded on wood, Ryton” coated on aluminum, and mirror-polished stainless steel. Polyethylene, however, does have a tendency to melt in respons to friction. Ultimately, the choice of panel material will vary depending on the type of belt used.
  • Air springs 25 are used to support three-ply plate 1 with respect to the treadmill frame and also to provide shock absorption and vibration isolation. Air springs 25 are locate in a parallelogram arrangement near the corners of plate 12 as is shown in Fig. 1. This arrangement suspends the plate/tread structure completely on air springs 25 and plate 12 is not cantilevered or otherwise partially suspended. An arrangement of three springs may also be used; however, the parallelogram arrangement improves stability.
  • Air springs are high strength flexible air container sealed by retainers at each end. Air pressure inside the flexible container serves as an energy absorbing medium which absorbs shock and vibration.
  • Fig. 2A shows an air spring in isolation.
  • the flex member 28 is built with a rubber lining and outer cover, reinforced with high strength synthetic fabric. Flex member 28 is fitted with rust-resi ⁇ tent retainer 30, 31 at each end. As shown in Figs. 2B and 2C, in the preferred embodiment, both retainers have blind taps 34 used for mounting air spring 25 to plate 12 and the frame 19.
  • Upper retainer 30 also contains an air fitting 36. Air fitting 36 may be used to initially fill the air spring with the appropriate mass of air and to periodically adjust the air pressure level as desired. Suspension devices other than airsprings are operable.
  • air spring suspension provides benefits in partially-suspended as well as fully suspended devices.
  • Air springs are available from several manufacturers in several sizes. In the present use, the air spring should provide a suitable suspension system for a wide range of user weight and ability. The force of the user's footfalls, and therefore the load on the treadmill suspension system, increases in proportion to the weight of the user and the speed at which the user walks or runs. The shock absorption capacity of air spring 25 should therefore increase as user weight and walk/run speed increases.
  • FIG. 3 contains a representative force vs. height curve for this air spring when inflated to 20 pounds per square inch (psi) (138 kPa) of air pressure.

  • the initial at-rest position of air spring 25 will be its noncollapsed height.
  • the noncollapsed height of the airsprings must be limited in actual use or unrestrained re-expansion of the air ⁇ pring after compression will blow the airspring apart.
  • studs with urethane bumpers are attached to plate 12 and travel through frame 19.
  • the urethane bumpers rest against the frame and keep airsprings 25 from overextending.
  • compression springs may be used instead of bumpers.
  • the initial noncollapsed position 37a corresponds to a spring height of approximately 3.8 inches (9.6 cm).
  • air spring 25 compresses in response the person's weight and the impact force of the person's footfalls. A heavier or stronger person will impart more of force to the treadmill and compress springs 25 further than a lighter or weaker person.
  • a light ⁇ weight person, running slowly might compress the spring from its initial height to a height of 3.5 inches (8.9 cm).
  • the spring of Fig. 3 returns a force of 125 pound (556 N) .
  • the suspension system therefore provides a nonlinea response, returning a larger force for heavier, stronger user and a smaller force for lighter, weaker users.
  • This nonlinea characteristic of the air spring suspension system ensures th the suspension does not become stiff as user size and or running speed increases and permits absorption of shockloads imparted to the treadmill by a wide spectrum of users.
  • Air springs provide a smoother fe than conventional steel springs because air is a compressible gas and because of the unique design of the air spring. Furthermore, air springs absorb energy whereas steel springs return substantially all the energy. Air springs thus dissipate a significant portion of the impact and vibration energy as heat.
  • the inflatable nature of the air spring also means the suspension system can be further adjusted during routine servicing to accommodate users of different sizes and abiliti as well as user preferences.
  • Deflating the spring causes the load curve of Fig. 3 to shift vertically downward.
  • the sprin thus returns smaller magnitude forces at the lower inflation value than are returned at the 20 psi inflation value graphed in Fig. 3.
  • inflating the spring to a value great than 20 psi shifts the load/force curve vertically upward resulting in forces of increased magnitude.
  • Varying the inflation level of the spring 25 can therefore be used to control the stiffness of the suspension system to accommodate both user size and user preference.
  • the nonlinear load curve and adjustable inflation of air springs 25 enables the suspension system of the present invention to accommodate a wide range of users. People of all sizes and abilities, therefore, derive equal benefit from the suspension system.
  • Inflation of air springs 25 installed on the treadmill to the desired value is achieved, e.g., by removing the ply 12c to reveal the plywood middle layer 12b of three- ply plate 12. Holes cut in the plywood layer 12b give access to fill valve 36 located on the retainer 30 of air spring 25. An inflation value of 11-8 pounds per square inch (about 28-55 kPa) is satisfactory for most users. At lower inflation levels, the suspension system has a more forgiving feel.
  • Replacement of air springs 25 can be accomplished once ply 12c is removed by removal of frame sidepiece 20. As shown in Figs. 4 and 5, removal of bolts 42a-f permits removal of sidepiece 20 providing access to the air spring 25. Remova of bolts 43 allows removal of air spring.
  • Air spring 25 can then be repaired or replaced by lifting plate 12 to clear the valve stem. Deflating the shock is required for replacement. Tread removal is additionally necessary for air spring replacement on the left side of the machine.
  • Fig. 4A shows that removable sidepiece 20 is preferably formed from a channe beam 44.
  • Channel beam 44 is a structural member of frame 19 and is therefore preferably fabricated as a single piece.
  • the channel beam secures to frame 19 with six bolts, labelled 42a- f in the drawings.
  • the bolt structure is designed such that the nut is retained in a spring clip structure 46 which is mounted as a plate directly behind channel 44. The bolt can thus be threaded through the sidepiece channel and into the nut from the outside of the sidepiece structure.
