Definitions
- the present invention relates to exercise methods and apparatus and more particularly, to exercise equipment which facilitates foot travel through various paths.
- Exercise equipment has been designed to facilitate a variety of lower body exercise motions.
- treadmills allow a person to walk or run in place; stepper machines allow a person to climb in place; bicycle machines allow a person to pedal in place; other machines allow a person to skate and/or stride in place; and still other machines guide a person's feet through elliptical paths of travel.
- Yet another exercise apparatus disclosed in U.S. Pat. No. 5,290,211 to Stearns, is designed to facilitate several different exercise motions, including free form paths of foot movement and controlled paths of foot movement comparable to walking, running, stepping, cycling, striding, skiing, and/or elliptical motion.
- the present invention provides an exercise apparatus which facilitates a natural walking motion like a treadmill but with greater flexibility and/or less potential for injury.
- left and right foot supports are pivotally mounted on left and right skates.
- the skates are movable back and forth relative to a base, and the foot supports are movable up and down relative to the skates.
- a person's feet are supported throughout a natural striding motion.
- both the length of each stride and the speed of foot motion may be varied at the discretion of the user.
- the foot supports are disposed above a deck, which provides a stable surface for mounting and dismounting the foot platforms, and which also shrouds the skates and associated linkage components.
- Bars extend through slots in the deck to connect the foot supports to the skates.
- the skates are constrained to move back and forth in reciprocal fashion, and the foot platforms are constrained to move up and down in reciprocal fashion. Rearward movement of the skates causes a flywheel to rotate subject to variable resistance. Resistance devices are also interconnected between the foot platforms and the skates to resist downward pivoting of the former relative to the latter.
- the entire foot supporting assembly is mounted on a base which may be pivoted relative to a forward stanchion to facilitate storage and/or transportation of the preferred embodiment machine.
- Another aspect of the present invention is to facilitate various modes of exercise motion involving left and right foot supports movably mounted on a base.
- the foot supports are free to move both back and forth and up and down relative to the base.
- the foot supports are free only to move up and down relative to the base, in a manner similar to a stair-stepping motion.
- the foot supports are free only to move back and forth relative to the base, in a manner similar to a skiing motion.
- handles may be movably mounted on the base and linked to the foot linkage assemblies.
- Figure 1 is a perspective view of an exercise apparatus constructed according to the principles of the present invention
- Figure 2 is a perspective view of the exercise apparatus of Figure 1 folded into a storage configuration
- Figure 3 is a perspective view of the linkage assembly on the exercise apparatus of Figure 1;
- Figure 4 is another perspective view of the linkage assembly of Figure 3;
- Figure 5 is yet another perspective view of the linkage assembly of
- Figure 6 is a perspective view of another linkage assembly constructed according to the principles of the present invention.
- Figure 7 is another perspective view of the linkage assembly of Figure 6.
- a preferred embodiment of the present invention is designated as 100 in Figures 1-2.
- the exercise apparatus 100 includes a base 110, a floor engaging support frame 120 connected to the base 110, two stationary handles 130 mounted on the support frame 120, and two foot supporting members 140 movably mounted relative to the base 110 via a linkage assembly 150 shown in Figures 3-5.
- the apparatus 100 is generally symmetrical about a vertical plane extending longitudinally through the center of the base 110, and like reference numerals are used to designate both the "right-hand" and "left-hand” parts.
- the base 110 is a shroud or housing which extends from a forward end 111 to a rearward end 112, and which has an upwardly facing deck 113.
- the deck 113 is sufficiently strong and spacious to support a person in a standing position rearward of the foot supporting members 140. Left and right, longitudinally extending slots 114 are provided in the deck 113 for reasons discussed below.
- the frame 120 includes a floor engaging portion 126 which is rotatably mounted to the base 110 at a pivot axis W and maintains the forward end 111 of the base 110 above the floor surface.
- a spring-loaded extension member 115 has a rearward end rotatably connected to a rearward portion of the base 110 at a first pivot axis XI, and a forward end rotatably connected to a rearward portion of the frame 120 at a second pivot axis X2.
- the extension member 115 is compressed between the base 110 and the frame 120 and urges the rearward end 112 of the base 110 upward once the axis XI is moved above a line drawn between the axis X2 and the axis W.
- the frame 120 also includes an upright portion or stanchion 128 which extends upward from the floor engaging portion 126.
- the distal ends of the stanchion 128 are bent rearward to provide fixed handles 130.
- a user interface device 190 is mounted on top of the stanchion 128 to provide information regarding the apparatus 100 and/or a person's performance while using the apparatus 100.
- a leaf-spring latch 129 is mounted on one side of the stanchion 128 and arranged to snap into a recess or cavity 119 on the base 110 when the latter is rotated to a vertical orientation (as shown in Figure 2).
- the handles 130 are spaced far enough apart to accommodate the rear end 112 of the base 110 therebetween.
- Wheels 127 are rotatably mounted on the forward end of the frame 120 to facilitate movement of the apparatus 100 across a floor surface. In both Figures 1 and 2, the wheels 127 are disposed slightly above the floor surface, and thus, the apparatus 100 must be tilted forward to bring the wheels 127 into contact with the floor surface. A similar wheel arrangement could be provided on the rearward end of the frame 120, if it would be preferable to tilt the apparatus in the opposite direction.
- Each of the foot supporting members 140 includes a skate 141 and a foot platform 145 (a modified skate is designated as 141' in Figure 3 for reasons discussed below). Rollers 144 are rotatably mounted on opposite sides of each skate 141, and tracks 104 are provided on the base 110 to receive and guide the rollers 144.
- skates 141 are supported by the base 110 and movable back and forth relative thereto.
- Flexible connectors 151-154 are interconnected between the skates 141 and routed relative to the base 110 in such a manner that the skates 141 are constrained to move back and forth in reciprocal fashion relative to the base 110.
- the connectors 151-153 link rearward movement of the skates 141 to rotation of a flywheel shaft 166 and associated flywheel 169.
- the distal connectors 151 and 153 are timing belts having ridges which register with notches or teeth on respective one-way clutch mechanisms 161 on the shaft 166.
- Other types of linkage arrangements, including chains or repeatedly wrapped cords, may be used in lieu of timing belts.
- the intermediate cable segment 152 is interconnected between the distal segments 151 and 153 and routed about two pulleys or other guides which occupy the positions designated as 162 and 163 in Figure 5.
- the other cable segment 154 is similarly routed about two similar, axially aligned guides on the base 110.
- the flywheel 169 may be "stepped-up" and/or subjected to any of several known resistance devices as a matter of design choice.
- an L-shaped bar 147 has a relatively longer segment which is disposed above the deck 113 and supports a foot platform 145, and a relatively shorter segment which extends through a slot 114 in the deck 113 and is connected to a triangular plate or yoke 149.
- a first vertex of the plate 149 is pivotally mounted to the skate 141.
- a second vertex of the plate 149 is connected to a flexible connector 159, as further explained below.
- a third vertex of the plate 149 is pivotally connected to a forward end of a connector link 179.
- An opposite, rearward end of the connector link 179 is pivotally connected to a forward end of a triangular rocker link 177.
- An intermediate portion of the rocker link 177 is pivotally connected to the skate
- rocker link 177 is pivotally connected to a resistance device 175.
- the resistance device 175 is a combination shock absorber and spring having a relatively forward, rod portion which telescopes relative to a relatively rearward, cylinder portion.
- a relatively forward, rod portion which telescopes relative to a relatively rearward, cylinder portion.
- An example of such a device is disclosed in U.S. Pat. No. 5,072,928 to Stearns.
- Other suitable resistance devices including a block of rubber, may be used in the alternative.
- the spring may be provided in lieu of or apart from the shock absorber, and arranged in other suitable ways relative to the other components.
- An advantage of the depicted embodiment 100 is that the parts are arranged to provide progressively increasing resistance to downward movement of the foot platform 145.
- the rocker link 177 pivots about a first axis relative to the skate 141; the connector link 179 pivots about a second axis relative to the plate 149; and the connector link and the rocker link 177 define a third pivot axis which moves toward a line drawn between the first axis and the second axis, as the foot platform 145 moves downward relative to the skate 141 (thereby decreasing the mechanical advantage or moment arm of the connector link 179 relative to the rocker link 177).
- the resistance device 175 pivots about a fourth axis relative to the skate 141; and the resistance device 175 and the rocker link 177 define a fifth pivot axis which moves away from a line drawn between the first axis and the second axis, as the foot platform 145 moves downward relative to the skate 141 (thereby increasing the mechanical advantage or moment arm of the resistance device 175 relative to the rocker link 177).
- the cable 159 is interconnected between each said plate 149 and is routed about similar pulleys or guides near the rear end of the base 110. The cable 159 causes either of the foot platforms 145 to move upward in response to downward movement of the other foot platform 145, and cooperates with gravity acting on the person's body to constrain the foot platforms 145 to move up and down in reciprocal fashion relative to the base 110.
- the apparatus 100 facilitates unrestricted foot movement through various types and sizes of paths having horizontal and/or vertical components.
- the apparatus 100 may also be readily modified in various ways to provide more restricted forms of exercise motion.
- Figure 3 shows an optional knob 108 protruding from a side of the base 110 and operable to selectively lock the skates
- a locking pin projects inward from the knob 108 and through a hole in the base 110, and a compressed helical spring biases the pin toward the right skate 141'.
- the knob 108 occupies a first orientation, the locking pin is held in a relatively outward position, clear of the right skate 141'.
- the left and right skates 141 and 141' are arranged side by side, and the knob 108 is rotated to a second orientation, the locking pin is urged inward into an aligned hole in the right skate
- Figure 3 also shows an optional detent pin 109 which is operable to selectively lock the foot platforms 145 against movement relative to the skates 141 and 141' (without impeding back and forth movement of the skates 141 and 141').
- the pin may be inserted into a hole 143 in an optional bracket 142 on the right skate 141' and into a similar hole in the bar 147' (when the foot platforms 145 occupy identical elevations).
- An alternative linkage assembly is designated as 250 in Figures 6-7.
- the linkage assembly 250 provides an alternative means for selecting between the different modes or types of foot motion, and it is suitable for use by itself or in conjunction with the linkage assembly 150 (in lieu of the arrangement shown with reference to the skate 141' in Figure 3).
- this alternative selecting means may be implemented on any two axially aligned pulleys associated with the cables 154 and 159, respectively.
- the assembly 250 is shown without any resistance devices simply to emphasize that the present invention should not be limited one way or the other. Among other things, a person's body weight, the inherent drag in the system, and the reciprocal nature of the foot motion may cooperate to impose a sufficient level of resistance to exercise.
- a flywheel and any desired flywheel resistance device may be operatively connected to one or both of the pulleys 262 and 264.
- Rollers 244 are rotatably mounted on opposite sides of the skates 241 to engage tracks similar to those on the preferred embodiment base 110.
- a continuous loop of cable 251 has a first portion secured to the left skate 241, a second portion routed about a forward pulley 261, a third portion secured to the right skate 241, and a fourth portion routed about a rearward pulley 262 (and returning to the left skate 241).
- the second and fourth cable portions are wrapped multiple times about respective pulleys 261 and 262 to ensure that back and forth movement of the skates 241 is linked to rotation of the pulleys 261 and 262.
- an L-shaped member 247 On each side of the assembly 250, an L-shaped member 247 has a relatively longer segment disposed above the skate 241 and supporting a foot platform 245, and a relatively shorter segment extending downward in front of the skate 241.
- a trunnion 242 extends upward and forward from the skate 241 to rotatably support the member 247 proximate the juncture between the longer segment and the shorter segment.
- a cord 254 is interconnected between the distal end of each said shorter segment and routed about a pulley 264 disposed beneath the pulley 262.
- This cord 254 is similarly wrapped multiple times about the pulley 264 to ensure that up and down movement of the foot platforms 245 is linked to rotation of the pulley 264.
- the foot platforms 245 are constrained to move up and down in reciprocal fashion.
- Various types of resistance means including the arrangement shown on the linkage assembly 150, may be interconnected between the foot platforms 245 and the skates 241 to resist downward pivoting of the former relative to the latter.
- the alternative selecting means includes an adjustment member 282 having an axially extending ridge or key 283, thereby giving the member 282 a non-circular cross-section.
- the adjustment member 282 is rotatably and slidably mounted on a support member 281, which is preferably a linear actuator anchored relative to the base (not shown).
- the adjustment member 282 is connected to a controller 289 by means of a wire 287.
- the controller 289 includes a lever 288 or other suitable input device which may be incorporated into a user interface like that designated as 190 in Figures 1-2.
- the member 282 is selectively movable relative to the base and into a keyway 263 in the pulley 262 and/or a similar keyway in the pulley 264.
- the key 283 on the adjustment member 282 interengages a similar keyway on the base when disposed entirely above the lower pulley 264.
- Movement of the lever 288 causes movement of the adjustment member 282 with the following effects: (a) when the adjustment member 282 occupies an uppermost position, clear of both pulleys 262 and 264 (as shown in Figure 6), the skates 241 are free to move relative to the base, and the foot platforms 245 are free to move relative to respective skates 241, thereby facilitating free form motion having any desired horizontal component and any desired vertical component; (b) when the skates 241 are positioned side by side, and the adjustment member 282 is inserted into only the upper pulley 262, the key 283 remains engaged with the base and prevents rotation of the upper pulley 262, thereby preventing back and forth movement of the skates 241, and limiting foot movement to a stepping motion involving up and down pivoting of the foot platforms 245; and (c) when the adjustment member 282 is inserted through both pulleys 262 and 264, the key 283 disengages the base, and the pulleys 262 and 264 are constrained to rotate together, thereby
