Description

Dual treadmill fitness device with single rear roller

The present invention relates to fitness applications, particularly to fitness devices having more than one pedal, and each pedal unit shares a common rear roller.

A recent development in the fitness equipment industry is an exercise device having a separate treadmill (hereinafter referred to as a "pedal") for each foot of a user. The exercise device can be constructed such that each pedal pivots near its rear end during use. Typically, each pedal includes a frame that supports a belt that extends around a front roller and a rear roller in a loop. The exercise device can also include a motor coupled to the rear rollers for driving the belt around the pedal frame. Each of the rear rollers of each pedal has an inner end portion that must be supported in a rotatable manner. In general, a sturdy axle train extends through two rear rollers. The outer ends of the axles of each of the rear rollers are rotatably supported to allow the rollers to be driven directly or indirectly by the motor. The inner ends of the axles of each roller are generally rotatably supported by a bracket to help stabilize such rear rollers during use and to minimize any deflection.

The support structure for the inner ends of the rear rollers may sometimes include one or more bearings for supporting the rear axles in the brackets on. As such, these support structures require sufficient space between adjacent pedals to facilitate mating between the inner ends of the rollers. This space requires a user of the exercise device to keep his foot apart a specific distance when using the exercise device, in order to prevent stepping on or in the side edges of the pedal during use, which may It is inconvenient. The need for two internal support structures and associated bearings also adds to the cost of manufacturing the exercise device.

An exercise device 10 consistent with the concepts of the present invention can be constructed to provide a user with a walking type of exercise, a stepping type of exercise, or a similar hill climbing exercise that combines walking and pedaling. The exercise device generally includes two treadmill-like components 12 (referred to herein as a "pedal" or a "pedal assembly") that are pivotally coupled to a frame such that These pedals can pivot up and down about a main shaft 16. The spindle can be a solid spindle (axle) or can be a virtual spindle defined by a component assembly that pivotally supports each pedal. In one embodiment Each of the pedals includes a tread belt 18 that provides a moving surface like a treadmill. In one example, the tread belt is supported by a front roller and a rear roller. The rear roller can be common to the two pedals, or each pedal can include a different rear roller. Furthermore, the or the rear rollers may be supported on the frame or pedal and may use a spindle with the pedals or may have a front, rear, and upper side of the pivoting spindles of the pedals and / or a unique rotating spindle below.

In use, a user will walk, jog, or run on the pedals, and the pedals will reciprocate back and forth against the pivoting spindle of the pedal. The pedals are interconnected such that the upward movement of one pedal is accompanied by the downward movement of the other pedal. The combination of the moving surfaces of the tread belts and the coordinated and interconnected reciprocating back and forth movement of the pedals provides an exercise similar to crawling on a loose surface, such as walking up, jogging, or running a A dune where each of the upward and forward foot movements is accompanied by a backward and downward sliding of the other foot. Extraordinary cardiovascular and other health benefits are achieved through this kind of crawling-like exercise. Again, as will be appreciated from the discussion below, such extraordinary health benefits are achieved in a low impact manner.

As discussed in more detail below, in one embodiment, the opposite end portions of the rear roller are rotatably supported at the rear end of the frame. The outer side of the rear end portion of the pedal is rotatably supported by the outer end portion of the rear roller. However, the inner side of the end portion of the pedal does not roll with the rear side The columns are joined, but instead are joined to the frame via an internal support structure that defines a virtual pivot. More particularly, the inner support structure includes a bracket extending rearwardly from the inner side of the pedals, the brackets being movably coupled to the at least one stud, and the stud bolts are coupled to the rear end of the frame Connected. As such, these pedals do not use an internal rear support structure that engages the rear rollers. The internal support structure thus allows each pedal to be positioned closer to each other along the inner side than to a comparable exercise device having two separate rear rollers. Even if the internal support structure is not directly seated in the pivotal position, the internal support structure allows the inner side of each pedal to move around a central pivot of the rear end of each pedal, as if It is supported at the central pivot. In a second embodiment of the exercise device discussed below, the pedals utilize an inner rear support structure coupled to the rear roller. The rear roller set in the second embodiment includes an annular groove that allows the belt to pass over the rear support structure, the rear support structure also allowing each pedal to be relatively tightly coupled to each other along the inner sides Positioning.

The following discussion provides a holistic structural architecture for various embodiments of a dual treadmill exercise device having a single rear roller. Further details regarding other structural architectures for the various embodiments discussed herein are provided in various related applications incorporated herein by reference. The concept of the present invention relates to various structures that can be used to support a pedal for an exercise device having a single rear roller.

Figure 1 is an example of an exercise device consistent with the concept of the present invention. Isometric view of the child. An embodiment of an exercise device shown in Figure 1 includes a protective and decorative panel 20 that, in some cases, obscures the line of sight of certain components of the exercise device. 2 is an isometric view of the exercise device of FIG. 1 with the protective and decorative panels removed to more clearly show all of the components of the device. In most cases, the views of the exercise device shown in Figures 3 through 8 and other figures do not include such protective and decorative panels.

Referring to Figures 1, 2 and other figures, the exercise device includes a first pedal assembly 12A and a second pedal assembly 12B, each pedal assembly having a front portion 22 and a rear portion 24. The rear portion of the pedal assembly 12 is pivotally supported at the rear of the exercise device 10. The front portion 22 of the pedal assemblies is supported above the frame 14 and is configured to reciprocate back and forth in a generally upward and downward manner during use. It is also possible to pivotally support the pedals in front of the exercise device and to support the rear of the pedal assemblies above the frame. The pedal assemblies each also support a recirculating belt or "tread belt" that rotates over a bottom plate 26 and against the front roller 28 and the rear roller 30 to provide a forward or backward movement. The moving surface.

A user may exercise on the device facing the front of the pedal assemblies (referred to herein as "forward facing use"), or may exercise on the device facing the rear of the pedal assemblies (in this context) Called "for rear use"). The words "front", "rear" and "right" are used herein to mean a front face that is usually used with the device. The way the party is standing on the device is used by the user. In any method of use, the user can walk, jog, run, and/or step on the exercise device in a manner in which each of the user's feet is in contact with one of the pedal assemblies. For example, during forward facing use, the user's left foot will generally only contact the left pedal assembly 12A, and the user's right foot will generally only contact the right pedal assembly 12B. Alternatively, in rearward facing use, the user's left foot will generally only contact the right side pedal assembly 12B, and the user's right foot will generally only contact the left side pedal assembly 12A.

An exercise device consistent with the concepts of the present invention can be constructed to provide only one stride action, and would only provide one step action. For a stride action, the pedal assemblies are constructed so as not to reciprocate back and forth, and the endless belts 18 are constructed to rotate. The term "stepping action" means any typical human stepping action, such as walking, jogging, and running. For a stepping action, the pedal assemblies are constructed to reciprocate back and forth, and the endless belts are constructed so as not to rotate about the rollers. The term "stepping" means any typical stepping action, such as when a human goes up the stairs, uses a traditional stepper fitness device, walks up a hill, and so on.

As mentioned above, the rear portion 24 of each pedal assembly is pivotally supported behind the exercise device. The front portion of each pedal assembly is supported above the front portion of the exercise device such that the pedal assemblies can pivot up and down. When the user is on a stepping belt When the step 18 is stepped on, the associated pedal assemblies 12A, 12B (including the belts) will pivot downward. As will be described in more detail below, the pedal assemblies 12 are interconnected such that downward or upward movement of one pedal assembly will result in upward or downward movement of the other pedal assembly, respectively. Thus, when the user steps on a belt 18, the associated pedal assembly will pivot downward while the other pedal assembly will pivot upward. By constructing the pedal assemblies for upward and downward movement and constructing the tread belts to provide a moving stride surface, the user can achieve an exercise session that includes walking and A combination of steps.

With respect to the left and right pedal assemblies, the tread belt is removed to reveal the underlying belt platform or "bottom plate" 26, as well as the front roller 28 and the rear roller 30. In addition to this, the belt platform of the left pedal is partially cut away to show the pedal frame member located below. Referring to Figure 2 and other figures, the exercise device includes a main frame 14 located below. The frame provides general structural support for moving the components of the exercise device as well as other components. The frame includes a left side member 32, a right side member 34, and a plurality of cross members 36 interconnecting the left side member and the right side member to provide a single Base structure. The frame can be placed directly on the floor or can be supported on adjustable struts, bumpers, shock absorbers, or a combination of such devices. In the embodiment of Figure 2, an adjustable strut 38 is provided The bottom of the frame is on the left side of the front side and the corner on the front right side.

A left side post 40 is coupled to the front end region of the left side member 32. One right side post 42 is coupled to the front end portion of the right side side member 34. The posts extend generally from the frame with a slightly rearward sweep. The handle 44 extends transversely to the top of each post in an orientation generally T-shaped with the post. The top of the T-shape is the handle, and the portion of the T-shaped downward extending portion is the column. The handles are configured to be substantially in the same plane as the respective underlying side members 32, 34. The handles define a first section 46 that is coupled to the posts and a second section 48 that extends rearwardly in an angular orientation relative to the first section. The handle is adapted to allow the user to grasp during use of the exercise device. A console 50 is supported between the first sections of the handles. The console includes one or more cup holders, an exercise display, and one or more recesses for receiving keys, a big brother, or other personal items.

Referring to Figures 2-6, and other figures, each pedal assembly includes a pedal frame 52 having a left side member 54, a right side member 56, and a plurality of extensions between the left side and the right side member. Pedal cross member 58. As shown most clearly in Figures 10A, 11A and 11B, the outer side of each pedal The members 54, 56 are pivotally coupled to the rear main shaft (axle) 16 by a radial ball bearing 59. More particularly, the outer bracket 300 is coupled to the outer longitudinal members 54, 56. These outer brackets 300 include an extension 302 that is coupled to a bearing end 304. The bearing ends of the outer brackets are coupled to the rear roller 30 via radial radial bearings. It should be appreciated that the outer brackets may be separate components or integrally formed with the outer longitudinal members.

The front rollers 28 are rotatably supported in front of each of the pedal frames, and the rear rollers 30 are pivotally supported at the rear of each of the pedal frames. In order to adjust the tension of the tread belt and the trajectory, the front or rear roller can be connected to the pedal frame in an adjustable manner. In a particular embodiment as best shown in Figures 3, 3A and 4, each front roller is coupled to the front side of each individual pedal frame in an adjustable manner. The front roller includes an axle 60 that extends outwardly from the ends of the roller. The outwardly extending ends of the axle each define a threaded opening 62 and are supported in a channel 64 defined by the left pedal frame side member 54 and the right pedal frame The side member 56 is in the forward end portion. The passage defines a forwardly open end 66. A plate member 68 defining a threaded opening is secured to the left and right front end portions of the right side member such that the centerline of the opening 70 is aligned with the forwardly open end portion 66 of the passageway 64. A bolt is threaded into the threaded opening and engages a corresponding threaded opening in the end of the roller axle 60 that is supported in the passage. Alternatively, a spring is tied It is seated between the rear portion of the passage and the pivoting axle for biasing forward toward the pivoting axle. By adjusting one or two bolts at the ends of the axle, the corresponding end of the axle can be moved forward or backward in the passage to adjust the position of the front roller. The adjustment of the front roller can relax or tension the tread belt or change the travel of the tread belt.

The belt bottom plates 26 are seated on top of each of the pedal frames 52. The base plate may be bolted to the pedal frame, may be secured to the frame in combination with a floor cushion or floor suspension system, or may be loosely mounted to the pedal frame. Each belt bottom plate is seated between each of the front rollers 28 and the rear rollers 30 of each of the pedal assemblies 12A, 12B. The belt bottoms are sized to provide a landing platform for most or all of the above-mentioned routes of the tread belts 18.

The rear portion 24 of each pedal assembly is pivotally supported on the rear side of the frame, and the front side of each pedal assembly is supported by one or more damping members 76, an interconnecting member 78, or a combination thereof Above the frame, each pedal assembly 12 is pivotable up and down relative to the lower frame.

Referring to Figures 9, 10A, 10B and other figures, each pedal assembly 12 is pivotally supported above a rear support structure 306 of the main frame 14. More particularly, the rear support structure includes a rear drive casting 308 that is supported by a rear frame support 310. As discussed in more detail below, the drive bracket extending upwardly from the rear drive casting supports the rear roller in a rotatable manner The opposite end portions of the post 30. An inner support structure 312 pivotally supporting the inner side of the pedal frame includes a mounting block 314 that extends upwardly from the rear drive casting between the opposite end portions thereof. As discussed in more detail below, the mounting block system supports the longitudinal members 54, 56 of the inside of the pedal frame 52.

As shown in Figures 10B-10C, the axle ends 316A, 316B of the rear roller 30 are rotatably supported by a left drive bracket 84A and a right drive bracket 84B above the rear drive casting 308. Corresponding radial bearings 81A and 81B rotatably support the axle ends in the brackets. Thus, the rear roller is rotatably supported about a common drive spindle 82 which also pivots the spindle 16 rearward of the pedals 12. As best shown in Figures 10A and 11B, the right and left drive brackets are bolted to a pair of flanges 318 that drive the opposite ends of the casting from the rear. The place extends upwards. While such drive brackets are bolted to the rear drive casting, it should be appreciated that the drive brackets can be coupled to the rear drive casting in any known manner, such as by screws. , welding, or other such fastening techniques.

As shown in FIGS. 10C, 11A, and 11B, the rear roller 30 includes right and left short end portions 320A, 320B, and the thick short ends are inserted into an elongated, generally cylindrical hollow. The opposite end portions of the tubular member 322. More particularly, the thick short ends each include a cylindrical portion that is coupled to an end cap portion 326. 324. The cylindrical portion of the thick short end portion is adapted to be received within one end portion of the hollow tubular member. When the rear roller is mounted on the exercise device, each pedal belt is positioned above the outer surface of the hollow tubular member. In some embodiments, the outer surface of the hollow tubular member includes a flanged region 328, as shown in Figure 10B. Referring to Figure 10C, the diameter of the end cap portion is greater than the diameter of the cylindrical portion of each of the thick and short ends, defining an annular frame edge 330 therebetween. The annular frame edge acts like a top that defines the maximum distance that the thick short ends can be inserted into the hollow tubular member. The thick and short ends of the axles can be coupled to the hollow tubular member in a variety of ways. For example, in one embodiment, the cylindrical portion of the stub end of each axle is depressed and fitted into the end portion of the hollow tubular member. Other attachment methods can be used, such as welding, fixing screws, keyways, or the like. As shown in Fig. 10C, the left and right axle ends 316A, 316B extend from the left stub end portion 320A and the end stub portion 326 of the right stub end 320B. When installed, the thick short ends are constructed such that the end portions of the axle extend outwardly from the thick short ends in pain and expansion with the centerline of the hollow tubular member. As discussed in more detail below, an axle end may be adapted to be coupled to a pulley that is used to drive rotation of the rear roller. While the end cap portions are depicted as solid, it should be appreciated that the end cap portions can be constructed in other ways. For example, the end cap portions can include a plurality of spokes that are coupled to the cylindrical portion and the end of the axle. Furthermore, although the embodiment of the square roller described above includes a thick short end, it should It should be ascertained that the rear roller can be constructed in other ways. For example, other embodiments of the rear roller can include a continuous axle that extends through the roller and is coupled to the roller.

A pulley 86 is fastened to a portion of one of the axle ends. As shown in Figures 2, 3, 10C and other figures, in one particular embodiment, the drive pulley 86 is secured to the left axle end 316A. However, the drive pulley can be fastened to the right end region or somewhere between the left and right end regions along the length of the drive shaft. A motor 88 is fastened to a bottom panel 90 extending between the right side edge member 56 and the left side edge member 54 (best seen in the bottom view of Figure 8). A motor shaft 92 extends outwardly from the left side of the motor. The motor is mounted such that the motor shaft is generally parallel to the drive shaft 82. A flywheel 94 is secured to the outwardly extending end region of the motor shaft. A drive belt 96 is coupled between the drive shaft pulley and a motor pulley 98, and the motor pulley is coupled to the motor shaft. Accordingly, the motor is configured to cause rotation of the left axle end 316A and the rear roller 30.

As mentioned previously, the inner support structure 312 acts to support the longitudinal members 54, 56 of the inner sides of the pedal frames 14. More particularly, the inner support structure includes an inner bracket 332 extending from a pedal frame slidably coupled to the studs 334A, 334B, and the thick short ends are from the mounting block 314 Extend out from the opposite side. It should be ascertained that these internal brackets can be separate components or The longitudinal members of the inner side are integrally formed. In addition, the mounting block may be integral with the rear drive casting or may comprise a separate piece that is coupled to the rear drive casting. In the embodiment illustrated in Figure 12A, the mounting block is positioned intermediate the rear drive casting and is extended upwardly through the rear drive casting fastener. As shown in Figure 12B, the mounting block also includes a concave curved top surface 336 that follows the shape of the square roller 30 that is positioned above. As discussed in more detail below, the studs 334A, 334B are supported through the front and rear openings 340A, 340B of the mounting block. As shown in Figure 14, the front aperture is positioned relatively higher than the rear aperture.

As previously mentioned, the inner brackets that are coupled to the pedal frames are slidably coupled to the studs on the mounting block and act to support the longitudinal members of the inner sides of the pedal frames. As shown in Figure 12B, the inner brackets 332 include curved portions 338 that extend downwardly and rearwardly from the rear ends of the inner longitudinal members 54, 56. The curved portions of the inner brackets each define at least one of the elongated holes 342 therein that are slidably supported by studs 334A, 334B extending from the mounting block. As each pedal pivots about the rear pivoting spindle 16, the studs on the mounting block slide through the elongated holes and thereby support the inner longitudinal members of the pedal frame. The curved portions of the inner brackets and the intersecting portions of the studs define a virtual pivot 344 having a pivot center shared with the rear pivoting main shaft. The virtual pivot eliminates the direct connection of the inner end of the pedal frame to the rear roller Need. While these inner brackets have curved portions and curved elongated holes, it should be appreciated that the inner brackets do not need to have curved portions. As shown in FIGS. 12A and 12B, two recessed portions 346 are formed on the top surface of the rear drive casting 308 adjacent to the opposite side edges of the mounting block 314. The two recesses allow the bottom surface of the curved portion of the inner bracket to be moved back and forth without impacting or contacting the upper surface of the rear drive casting.

In a particular embodiment, two arcuate elongated holes are formed in the curved portion of each of the inner brackets, and the curved portions are corresponding studs 334A, 334B extending from the mounting block 314. Supported. More specifically, as shown in Fig. 12B, the curved portion of each of the inner brackets includes a front slit hole 342A and a rear slit hole 342B which are respectively adapted to receive the front stud 334A and the rear stud 334B. Having the two elongated holes supported by the two studs helps provide sufficient lateral and longitudinal support to create sufficient rigidity to support the inside of each pedal during the pivoting motion. While each inner bracket includes two elongated apertures seated therein, other embodiments include a single elongated aperture supported by a single stud. The curved portion of each of the elongated holes is at least partially defined by a distance from a center of rotation formed by the elongated holes, and the length of the elongated holes along the curved portion is at least partially The pedal is allowed to be defined by the distance pivoted on a particular component of the exercise device. In a particular embodiment, each of the elongated apertures defines an arcuate arcuate section having a length defined by the amount of pivotal movement of each pedal through which it moves during use. Curvature of each arc The center of the radius is the rear pivoting spindle, which is also the same center of the rotating spindle of the square roller as shown here. It should be appreciated that in other embodiments, the rear roller may be offset from the rear pivoting spindle for performance or other technical reasons.

As previously mentioned, each of the elongated holes 342A, 342B in the inner bracket is adapted to receive corresponding studs 334A, 334B on the mounting block 314. Thus, the inner brackets extending from each of the pedals are supported on opposite sides of the mounting block as shown in Fig. 12A. The studs are preferably tightly fitted within the elongate holes while being easily slidable along the elongate holes so as not to create any undesirable friction. Figure 12B shows the construction of the studs 334A, 334B, which in one embodiment are used to support the inner brackets 332. In particular, as shown in Figure 12B, each stud includes at least one penetration bolt 348 having a head portion 350 and a nut portion 352. A clamp collar 354 is seated at the opposite end of each bolt. More particularly, the clamp collar 354 has a hollow jacket section 356 that fits over a portion of the bolt and a flange portion 358 that extends radially from the hollow jacket section. The flange portion of a clamp collar is positioned adjacent the head of the bolt and the flange portion of the clamp collar is positioned adjacent the nut. A first friction bushing (washer) 360 is positioned around the jacket section 356 between the inner bracket 332 and the flange portion 354 of each of the clamp collars. The first friction bushing can be made from a variety of materials. For example, in one embodiment, the friction bushing is made of IGUS L280 or a similar material. A bearing 362 is positioned on either side of the mounting block and around the jacket section of the clamp collar. The bearing can be constructed in a variety of ways. For example, the bearing can be a sealed cartridge bearing, such as a ball bearing, or can be made of a solid construction material such as IGUS L280 or a similar material. A second friction bushing (gasket) 364 is positioned between each of the inner brackets 332 and each side of the mounting block 314. The second bushing is also positioned above the jacket section of the clamp collar. The second friction bushing can be made from a variety of materials such as Teflon ^(TM) or other friction reducing materials. The isometric linings are sized to extend beyond the edges of the elongated holes in the inner bracket to prevent the inner brackets from rubbing against the mounting block. Each bearing has a diameter that is configured to fit snugly within each of the elongated holes and provides a surface to which the walls of the elongated holes are attached when the pedals are pivoted up and down about the wheel axis The surface slides. It should be appreciated that different stud structures can be used to provide a sliding surface for the inner brackets and should not be limited to those described and depicted herein. As discussed below with reference to Figures 21A through 25D, as the pedals are pivoted up and down, the elongated apertures in the inner brackets slide along the map.

A belt speed sensor 100 is operatively coupled to the tread belt 18 for monitoring the speed of the tread belt. In a particular embodiment, the belt speed sensor is implemented by a reed switch 102 that includes a magnet 104 and a detector 106. The reed open relationship is operatively coupled to the drive pulley for generating a belt speed signal. a magnet is embedded in the drive pulley or The drive pulley 86 is coupled to the drive frame 86 and coupled to the main frame 14 in a predetermined orientation for generating an output pulse each time the magnet rotates past the detector.

As mentioned previously, the rear roller 30 is secured to the drive shaft 82. Thus, the rotation of the drive shaft causes the rear roller to rotate and also causes the associated endless belt 18 to rotate at the same, or nearly the same, pace. The motor can be constructed or commanded by the user's control to drive the endless belts in a forward direction (ie, from the left side, counterclockwise around the front and rear rollers), or It is constructed to drive the endless belts in a rearward direction (i.e., from the left side, clockwise around the front and rear rollers).

During use, the tread belt 18 is slid over the bottom plate 26 with a special dynamic frictional force depending on various factors including the material of the belt and the bottom plate, and the downward force on the belt. In some cases, when the user steps on the belt and increases the dynamic friction between the belt and the bottom plate, the belt may stick slightly to the bottom plate. In addition to the force provided by the motor 88 to rotate the belts, the flywheel 94 secured to the motor shaft has an angular momentum component that helps overcome the increased dynamic friction and Helps provide a uniform pedaling belt movement. In one embodiment, the substrate is a 3/8 inch thick intermediate density fiber (or "MDF") based on a coating of a low-friction curing of an electron beam. In addition, the belt is a polyester fabric base with a PVC top. The belt can be combined with a low friction material such as a low friction resin.

Certain embodiments of the invention may include a resistance element 76 that is operatively coupled to the pedals. As used herein, the term "resistance element" is meant to include any type of device, structure, member, assembly, and construction that resists vertical motion such as the pivotal motion of the pedals. The resistance provided by the resistance element can be fixed, variable, and/or adjustable. In addition, the resistance can be a function of load, time, heat, or other factors. Such a resistance element can provide other functions, such as mitigating the downward, upward, or both movements of the pedals. The resistive element can also apply a restoring force to the pedals such that if the pedal is in a lower position, the resistive element will apply a restoring force to move the pedal upwards; or if the pedal If it is in an upper position, the resistance element will apply a restoring force to move the pedal down. The term "impact member" or "damping element" is sometimes used herein to mean a resistance element, or a spring (recovery force) element, or one may or may not include a spring (return). Damping element of force.

In a particular configuration of the exercise device, a resistance element 76 extends between each of the pedal assemblies 12 and the frame 14 for supporting the front side of the pedal assembly and for resisting downward movement of each of the pedals. The or the resistance elements can be disposed at various locations between the pedal frame and the main frame. In the embodiment shown in Figures 1 through 7, and other figures, the resistance elements include a first impact member 108 and a second impact member 110. Both impact members resist and cushion the movement of the pedals. More particularly, the first or left impact member 108 is extended Between the left side of the left pedal assembly or the outer frame member 54 and the frame member 40 of the left upright. The second impact member 110 extends between the right side of the right pedal assembly or the outer frame member 56 and the frame member 42 of the right upright. In an alternate embodiment, the impact members extend between the outer frame member of each of the pedal assemblies and a portion of the frame below the pedal assembly. In another alternative, the impact members can be coupled to the front side of the pedals between the inner and outer pedal frame members.

In a particular embodiment, the impact member (108, 110) is a fluid or air type damping device and is not integrated internally or externally with a return spring. Thus, when a user's foot is placed in front of a pedal, the impact member restrains and resists the downward force of the foot to provide a foot, leg, and foot for the user. And the cushioning effect of various leg joints of the knee. In some configurations, the resistance device can also be adjusted to reduce or increase the downward stroke length of a pedal. The impact member can be provided with a user adjustable damper collar which, when rotated, causes the damping force of the impact member to increase or decrease to match the needs of any particular user. A special impact member that can be used in a fitness device in accordance with the present invention is shown and described in U.S. Patent No. 5,762,587, entitled "Exercise Machine With Adjustable-Resistance, Hydraulic Cylinder", the disclosure of which is incorporated herein by reference. This article is incorporated by reference in its entirety.

Generally, the impact member includes a cylinder that is filled with hydraulic fluid. A piston rod member extends outwardly from the cylinder. Within the cylinder, a piston system is coupled to the piston rod member. The piston system defines at least one orifice through which the hydraulic fluid can flow, and the piston also includes a check valve. The piston subdivides the cylinder into two fluid-filled chambers. During the starting of the impact member, the piston moves up or down in the cylinder. During the downward movement or elongation of the impact member, the flow system flows through the orifice at a rate which is determined in part by the number of orifices and the size of the orifice. The flow system flows through the check valve during upward movement or compression of the impact member. The collar is operatively coupled to a panel to which the panel or apertures are associated. The rotation of the collar will expose or cover the orifice for fluid flow and thus reduce or increase the damping force of the impact member. Alternatively, the collar that inhibits resistance is coupled to a plunger that tapers toward an orifice between the hydraulic chambers of the impact member. The depth of the plunger is controlled in part by the resistance of the impact member. Preferably, the return spring shown in Figure 4 of the '587 patent is removed.

Another special impact member that can be used in an exercise device in accordance with the present invention is described and described in U.S. Patent No. 5,622,527, entitled "Independent Action Stepper," which issued on April 22, 1997, which is incorporated herein by reference. The overall content is incorporated herein by reference. The impact member can be used with the spring 252 shown in Figure 10 of the '527 patent. After the pedal is depressed, the spring provides a returning force that moves up or restores the pedals. Preferably, however, the spring 252 is removed. In this manner, in one embodiment of the invention, The impact member provides only one resistance and does not provide a return force. In an embodiment where no spring is used, the impact member can be configured to provide a resistance in the range of 47 KgF to 103 KgF. Alternative resistance elements are discussed in more detail below.

15 through 19 are partial isometric views of the exercise device specifically showing the interconnecting structure 78 of the pedal. 15 to 19 each show an interconnection structure among different positions. Fig. 20 is a side elevational view showing the structure in which the pedals are connected to each other, and the position thereof is the same as that shown in Fig. 17. 21(A, B) to 25(A, B) are isometric views of the exercise device corresponding to the views shown in Figs. 15 to 19. In a particular embodiment of the interconnect structure shown in Figures 15-20 and other figures, the interconnect structure includes an arcuate rocker pivotally supported on an arcuate rocker cross member 114. A rod or "rocker" arm assembly 112 extends between the left side side member 32 and the right side side member 34 of the frame. The components of the curved rocker arm are operatively coupled to each of the pedal assemblies 12. As best shown in Figure 20, the curved rocker cross member defines a U-shaped transverse section. Each of the upright portions of the U-shape defines a keyway 116 (see, for example, Figure 19). The top of the keyway defines a pivot opening 118. The curved rocker arm includes an arcuate rocker or interconnected pivoting axle 120 supported between and extending between each of the pivoting apertures for pivotally supporting the arc Rocker arm. As discussed in more detail below, the keyway provides a path for the interconnect structure to be moved between a "carry" position and a "use" position.

The left and right outer portions of the curved rocker arm include a first or left lower pivot stud 122 and a second or right lower pivot stud 124, respectively. A generally L-shaped bracket 126 supporting a first upper pivot stud 128 extends downwardly from the inner or right side member 56 of the left pedal 12A such that the upper pivot stud can be generally The upper side is parallel and supported below and outside the inner side member. A second generally L-shaped bracket 132 supporting a second upper pivot stud 130 extends downwardly from the inner or left side tubular member 54 of the right side pedal 12B such that the upper pivot stud It may be substantially parallel, supported below and outside the inner side members.

A first rod 134 is coupled between the left upper pivot peg 128 and the lower pivot peg 122. A second rod 136 is coupled between the right upper pivot peg 130 and the lower pivot peg 124. These levers connect the pedals to the curved rocker arms. In a particular embodiment, each of the bars (134, 136) defines a sleeve nut having an adjustable length. The sleeve nuts are attached to a ball joint 138 configuration with upper and lower pivot pins. A sleeve nut defines an upper and a lower threaded sleeve 140. Each threaded sleeve defines a circular cavity with opposite ends for supporting a pivoting ball. These pivot studs are supported in the pivoting ball. One of the bars defines opposing threaded ends 142, each of which is supported in a corresponding threaded sleeve.

As will be discussed in more detail below, the pedal assembly 12 can be locked so as not to pivot about the rear main shaft 16. When locked When in residence, the belt 18 of the pedal assembly will collectively provide an effective single non-pivoting stepping surface similar to a treadmill. By adjusting one or two of the sleeve nuts 134, 136 to rotate the length of the rod member 142 during or after the combination of the exercise device, the horizontal planes of the two pedals can be precisely aligned so that the two pedals are The belts will jointly provide parallel stepped surfaces in the locked position.

The interconnecting structure 78 (eg, the curved rocker arm assembly) interconnects the left and right pedals such that when a pedal (eg, a left pedal) is pivoted about the rear pivoting spindle 16 And then, when pivoting upward, the other pedal (eg, the right pedal) will pivot up and down about the rear pivoting spindle, respectively, and then pivot downward. Thus, the two pedals are interconnected in a manner to provide a step motion in which the downward movement of one pedal is accompanied by the upward movement of the other pedal and vice versa. During this stepping action, the curved rocker arm portion 112 pivots or swings about the curved rocker spindle 120, either alone or in conjunction with a striding motion.

While an embodiment of the pedal interconnect structure is constructed to have a "use" position and a "step" position, the exercise device can also be constructed to be partially disassembled and transported, with a The need for an interconnected structure that "steps on" the position. For example, the exercise device can be constructed to be transported among three boxes: a first case containing a base frame, a second case containing a pedal assembly, and a third case containing a post and a console. The second box containing the pedal assembly includes two pedals, and the two pedals include a pedal frame Rack, front and rear rollers, pedal bottom plate, pedal belt, drive bracket, rear drive casting, and internal support structure. The pedal assemblies are coupled to the base frame by attaching the rear drive casting to the rear frame support. The interconnecting structure can be transported as part of the pedal assembly, and when the pedal assembly is coupled to the frame, the interconnecting structure pivots the curved rocker arm to the curved rocker The rotor shafts are connected to each other directly to the frame.

Referring now to Figures 15 through 19 and Figures 21 (A, B) through Figure 25 (A, B), a hill-like exercise provided by the action of the exercise device 10 is described in more detail. A representative user (hereinafter referred to as "user") is shown in the front-facing use in FIGS. 16B to 20B. The user is walking forward and the device is constructed to be used for climbing type, i.e. such that the pedals will reciprocate back and forth. The foot motion shown in the figure is typical of only one user representative. In some cases, the pedals 12 cannot move between the uppermost and lowermost positions, but rather at a point in between. In some cases, the user may have a shorter or longer stride than shown. In some cases, a user can walk backwards, or can face rearward, or can face rearward and backward.

In FIGS. 15 and 21A, the left side pedal 12A is positioned in a lower position, and the right side pedal 12B is located in an upper position. Referring to Fig. 21C, the studs 334A, 334B on the mounting block 314 are positioned proximate to the forward end portions of the elongated holes 342A, 342B in the inner brackets 332 that are coupled to the left side pedal. Conversely, as shown As shown at 21D, the studs 334A, 334B on the mounting block 314 are positioned proximate to the rear end portions of the elongated holes 342A, 342B in the inner brackets 332 that are coupled to the right side pedal. Referring to Figures 15 and 19, the left side of the arc rocker arm portion 112 is pivoted downward and the right side of the arc rocker arm portion is pivoted upward. In Fig. 21B, the user is shown with his right foot forward and on the right side of the tread belt. In the orientation of the user as shown in FIG. 21B, during use of the forward facing type of climbing, the user's left leg will be extended downward and rearward, and most of the user's weight is on the left side. On the pedals. The user's right leg will bend at the knee and extend forward so that the user's right foot will begin to press down on the pedal on the right side. From the orientation shown in Figure 21B, the user will transfer their weight to a balance between the right leg and the left leg and begin to press down with their right leg to force the pedal on the right side down. . Due to the movement of the belts, the two feet will move rearward from the position shown in Figure 21B.

Figures 16 and 22A show the orientation of the device 10, and Figure 22B shows the user in a position subsequent to that shown in Figures 15, 21A and 21B. The right side pedal 12B is pressed down via the curved rocker interconnecting structure 78, causing the left side pedal 12A to begin to rise. The user's right foot has moved backward and downward from the position shown in Figure 21B. The user's left foot has moved back and up from the position shown in Figure 21B. In addition, as shown in Fig. 22C, the inner bracket connected to the left side pedal has been pivoted for positioning the studs 334A, 334B at the front end portions of the elongated holes 342A, 342B. rear. Further, as shown in Fig. 22D, the inner bracket connected to the right side pedal has been pivoted to position the studs 334A, 334B in front of the rear end portions of the elongated holes 342A, 342B.

17, 23A and 23B show that the right side pedal 12B is approximately midway through its upward stroke, and the left side pedal 12A is approximately midway through its downward stroke. As such, the pedal assemblies are at approximately the same level above the frame 14, and the endless belts 18 are also at the same level. As shown in Figures 23C through 23D, the studs are positioned at intermediate portions of the length of each of the elongated holes in the inner brackets that are coupled to the left and right pedals. As shown in Fig. 23B, the user's right and right legs have moved rearward and downward from the position shown in Fig. 23B. The left foot of the user has moved backward and upward from the position shown in Fig. 21B. At this point, the user has begun to lift the left foot from the tread belt on the left side in a forward step; therefore, the left heel is lifted and the user has rolled up the ball of the left foot. In general, the weight on the right pedal now is more than the weight on the left pedal.

After the orientation shown in Figures 17, 23A, and 23B, the right pedal 12B will continue its downward motion, and the left pedal 12A will continue its upward movement to reach Figures 18, 24A, and 24B. The orientation of the device is shown. In FIGS. 18, 24A, and 24B, the left pedal is higher than the right pedal, and the curved rocker arm 112 pivots about the pivoting main shaft 120 of the curved rocker so that the right side thereof is low. On the left side. In addition, as shown in FIG. 24C, the inner bracket connected to the left pedal It has been pivoted to position the studs 334A, 334B behind the intermediate portions of the elongated holes 342A, 342B. Further, as shown in Fig. 24D, the inner bracket connected to the right side pedal has been pivoted to position the studs 334A, 334B in front of the intermediate portions of the elongated holes 342A, 342B. In this position, the user's right leg continues to move backwards and downwards. The user has lifted the right leg off the left pedal and moved it forward. At approximately the upper position of the left pedal, the user will step down on the front portion of the pedal belt with his left foot. The user's entire weight will be on the right pedal until the user places their left foot on the left pedal. The user continues to provide a downward force on the right pedal, forcing the left pedal to go up.

19, 25A, and 25B show that the right side pedal 12B is approximately in its lowest position, and shows that the left side pedal 12A is approximately in its highest position. Referring to Fig. 25C, the studs 334A, 334B on the mounting block 314 are positioned at the rear end portions of the elongated holes 342A, 342B in the inner bracket 332 which is connected to the left side pedal. Conversely, as shown in Fig. 25D, the studs 334A, 334B on the mounting block 314 are positioned at the front end portion of the elongated holes 342A, 342B in the inner bracket 332 which is connected to the right side pedal. . At this point, the user has stepped down on the front portion 22 of the left pedal and has begun to press down with the left leg. The user also began to lift his right leg. The downward force on the left pedal will be transmitted through the interconnecting structure 78 to the right pedal to cause the right pedal to begin to rise.

Figure 21 (A, B) to Figure 25 (A, B) show the pedals The half cycle of the reciprocating motion, that is, the movement of the left pedal from a lower position to an upper position and the movement of the right pedal from an upper position to a lower position. A complete climbing type of exercise cycle is represented by a pedal that starts from a position and returns to the same position in a manner that includes a full upward stroke of the pedal (from the lower position to the upper position) and A complete downward stroke of the pedal (from the upper position to the lower position). For example, a step cycle (upper position of the right pedal) involving the lower position of the left pedal will include motion of the left pedal going up from the lower position to the upper position and then down to the lower position. In another example, a step cycle (see Figure 23) relating to the midpoint position of the left pedal will include an upward movement of the pedal to the upper position, a downward movement from the upper position, and an intermediate position through the intermediate position. And the upward movement to the lower position and back to the midpoint position. The order in which the up and down pedals move is not important. Therefore, the upward movement can be followed by a downward movement or a downward movement followed by an upward movement.

Referring to Figure 15 and other figures, in a particular configuration, the exercise device includes a step sensor 144 that provides an output pulse corresponding to each downward stroke of each pedal. The step sensor is implemented by a second reed switch 146 that includes a magnet 148 and a detector 150. The magnet is attached to the end of a bracket 152 that extends upwardly from the curved rocker arm portion 112. The bracket is such that the magnet is oriented such that it will oscillate back and forth past the detector, and the detector is mounted to a holder that is coupled to the curved rocker cross member 114. On the shelf 157. The reed switch 146 triggers an output pulse each time the magnet 148 passes the detector 150. Thus, when the right side pedal 12B is moving downward, the reed open relationship transmits an output pulse corresponding to the magnet that passes down the detector, and when the left side pedal 12A is moving upward, the reed The switch also transmits an output pulse that corresponds to the motion of the magnet that passes up the detector. These output pulses are used to monitor the pedal's oscillation and stroke count as the pedal moves up and down during use. It is also possible to determine the size of the depth or vertical stroke by means of an additional sensor arranged substantially vertically. These output pulses can be used alone or in conjunction with belt speed signals to provide an exercise frequency display and can be used in various exercise related calculations, such as determining the user's calorie burn rate.

As best shown in Figures 3, 6, and 21A through 25, in a particular embodiment, each of the pedals includes a drop assembly 154. The drop assembly includes a generally V-shaped bracket 156 that is interconnected between the inner and outer sides of the pedal frame. The vortex region of the V-shaped styling bracket is oriented downwardly and generally defines a flat mounting surface 158. A block 160 is fixed to a portion of the mounting surface that faces downward. When the exercise device is assembled, it is preferred that the pedals are configured by the sleeve nut (134, 136) such that when the pedal is in its lowest position, the block 160 can be held slightly higher The locking cross member 162 is located below. A bumper 164 can be secured to the cross member 162 to mitigate the impact of the pedal if the pedal falls to a minimum. In one example, the block is a Made of hard, non-flexible plastic. The block can also be made of a sturdy or flexible elastomeric material. In a flexible, elastic form, the block will provide some cushioning to enhance the buffering provided by the buffer, or in the event that the buffer is not in use, in case of use. A buffer is provided when the locking cross member falls to the bottom.

As described above, the exercise device 10 can be constructed in a "lock-out" position in which the pedal assembly does not pivot up and down. In a particular locking orientation, the pedal assembly is pivotally secured such that the tread belts are parallel and are approximately at a 10% slope relative to the rear side of the exercise device. Thus, in a front-facing use, the user can simulate an uphill step, and in a rear-facing use, the user can simulate a downhill step.

A second embodiment of the exercise device has a single rear roller 30' as shown in Figures 26A-26E. As shown in Figures 26B and 26C, the inner longitudinal members 54, 56 of the pedal frames 52 are pivotally supported by internal brackets 332' extending therefrom. The inner brackets are not supported by a virtual pivoting structure as described above with reference to the first embodiment, but instead are rotatably coupled to the rear roller 30'. As shown in FIGS. 26C to 26E, an annular passage 366 is formed in the rear roller and surrounded by each of the inner brackets. More particularly, each of the inner brackets includes an extension 368 that is coupled to a rear bearing end 370, and the rear bearing ends are associated with the The rear rollers are coupled around the annular passage via bearings 371. As such, the inner bracket pivots about the rotating main axis of the rear roller. In addition to where the rear bearing end is joined to the extension of the inner bracket, each rear bearing end has an contour that does not extend beyond the outer diameter of the rear roller. The structure of the rear bearing ends allows the belt to pass through the annular passages without contacting the bearing ends.

As shown, Figures 26B through 26E show a single rear roller according to a second embodiment, the rear roller including three sections. A first section 372 is defined by a portion of the rear roller 30' adjacent the rear end of the left pedal 12A, and a second section 374 is defined by a portion of the rear roller 30' adjacent the rear end of the right pedal 12B. And a third section 376 is defined by a portion of the rear roller between the first and second sections. The axle ends 316A, 316B extend outwardly from opposite ends of the rear roller and are rotatably supported by the left and right drive brackets, as described above.

As mentioned previously, each bearing end receives a portion of the rear roller that corresponds to the annular passages. As shown in Figure 26C, each bearing end has a selectively removable portion 378. When the rear bearing end is coupled to the rear roller, the removable portion is interrupted from the inner bracket to create an opening in the end of the bearing. The bearing end is then placed in the annular passage and the removable portion is reattached. Once attached, the rear roller rotates within the ends of the bearings. As such, no frame members will support adjacent bearing ends. Instead, the bearing ends are supported by the rear rollers. As mentioned before, the outer peripheral surfaces of the bearing ends do not extend beyond the annular passages and thus do not interrupt the action of the belt while at the same time providing sufficient support for the interior of the pedals edge. The inner brackets on each of the pedal frames can be individually attached to the pedal frame as shown, or can be integrally formed with the frame, such as being welded or the like.

Since the support structure for the inner longitudinal member is integrated into the rear roller such that the inner edges can be sufficiently supported, the inner support structure as shown in FIGS. 26A to 26E allows the pedals The insides can be positioned closely to each other. Therefore, there is no size limitation on the need for the inner longitudinal members of the pedal to be separated.

As mentioned previously, the rear rollers according to the embodiments described above can be pivotally supported by the drive bracket in various ways. For example, Figure 27 shows the rear roller 30 supported by an adjustable axle support 380 that allows the vertical height of one end of the rear roller to be adjusted. Although FIG. 27 shows that the adjustable axle support is coupled to the right end of the rear roller, it should be appreciated that the adjustable axle support can be with the left end of the rear roller or two. The ends are connected. As shown in Figure 27, the adjustable axle support 380 includes an axle bracket 382 that is fixedly coupled to the right drive bracket 84B. A vertically oriented set screw 384 is coupled to the axle bracket from the right axle end extending from the rear roller. More particularly, the bolt is threaded through an opening 386 in the end of the right axle, and the bottom of the bolt extends from the opening and engages the axle support. Therefore, turning the bolt in one direction or the other direction will raise or lower the end of the axle on the right side. Since the right axle end is coupled to the axle bracket by the bolt, the right axle end does not rotate with the rear roller. Thus, the rear roller is rotatably supported by the end of the axle via a bearing or similar structure. It should be appreciated that the rear roller shown in Figure 27 can be supported by a separate axle extending through the rear roller or can be supported by the stubby ends described above. When the rear rollers shown in Fig. 27 are supported by the thick short ends, the end portions of the axles are not fixedly connected to the end caps, but instead are rotatably coupled via a bearing and the like. The end caps are joined. While the adjustable axle support provides adjustment of the vertical height for one end of the rear roller, it should be appreciated that the adjustable axle support can be constructed to provide the rear roller The ability of either end, or one end, or both ends to be adjusted forward or backward, or a combination of forward and backward, and vertical adjustment.
