DETAILED DESCRIPTION

As used herein the term “user” means a human being in the normal sense having a head, a torso, a waist, two arms with elbows, two hands, two legs with knees and two feet typically being between about 4 feet and about 7 feet tall.

FIG. 1 shows in schematic, a resistance subassembly 10 drivably interconnected to one or the other of two input assemblies 5a, 5b of an exercise apparatus. The two input assemblies are shown for illustration purposes how two different input assemblies with two different user manually engageable input mechanisms 5e can be arranged to operate together with a resistance subassembly 10 as shown and described herein.

As shown in FIGS. 1, 2, 3 three (3) resistance generating fans, 20, 22, 25 are mounted on mounted on a common drive axle 24. Depending on the precise configuration of the exercise apparatus 5, one or more fans 20, 22, 25 are preferred for use as a source of resistance to an exercise that may be performed using a particular apparatus 5.

A movement or motion in a “first direction” and in a “second direction that are generally opposite as used herein means two discrete physical movements in two directions that are different from each other in direction such as a lever, linkage, arm or leg moving forwardly and then backwardly, or a lever moving a first angular amount and then subsequently a second angular amount in the same direction or in different directions, or an arm travelling through a first path of travel of a first distance and then travelling through the same path of travel a second distance, or an arm travelling through a first path of travel a first distance and then travelling through another second path of travel a second distance. Generally opposite direction does not mean that the path of travel of the user input device takes in the first direction is the same or identical to the path that the user input device takes in the second opposite direction but only that the paths of travel in each direction are generally opposite. For example, generally opposite directions occurs in the motion of a pedal of an elliptical stride exercise machine where a pedal travels from front to back along a downwardly arcuate path and from back to front along an upwardly arcuate path of travel. Similarly, the motion of a handle or lever in an elliptical rowing machine can travel generally back and forth in an elliptical handle motion, namely generally opposite front to back and back to front directions but along different upwardly arcuate and downwardly arcuate paths of travel.

Generally, the path of travel of a user input device travels during the course of an exercise cycle from a first start position to a second most distant position and back to the first start position. The path of travel can be the same linear or arcuate path in each direction or the path of travel can be different from start to most distant position and back to start as in an elliptical motion.

The position of the start and most distant positions of the user input device relative to the frame, seat, foot supports and the like can be adjustable. Similarly the length or degree of incline or angular travel of the path of travel from the start to most distant positions of the user input device can be adjustable.

As shown, fans 20, 22 can comprise a fan that has blades 20b, 22b that generate a resistance R1, R2 to rotation of the fans 20, 22 by interference with ambient air or atmosphere upon rotations that varies non-linearly, typically by a cube factor, with the rate of rotation of the fans 20, 22 and the rate of travel of the user input device 5i along the paths of travel 6f, 6o.

Fan 25 comprises a disk component of a conventional rotating eddy current brake that increases or varies resistance non-linearly (for example exponentially) with the degree of increase in rotation of the fan 25.

In other embodiments of the present invention, the resistance apparatus can comprise the use of a single fan 20, 22 or 25. For example, when used in conjunction with the specific configurations of the FIGS. 4-10 exercise apparatuses, the source of resistance can comprise either a single disk 25 (and associated eddy current brake components) or to use a single fan 20, 22 as the source of resistance to movement of the user force input device of the apparatus. The use of such a single fan as the source of resistance can be configured to provide resistance to movement of the user force input device in either one movement or in two movements (such as in both the back and forth directions of movement of a lever) as described herein.

In other embodiments, the resistance apparatus can comprise the use of at least two (2) fans, for example a pair of fan fans 20, 22 or a pair of eddy current disks 25, or a combination of a single fan 20 and an eddy current disk 25. In embodiments where at least a pair of fans are used as the source of resistance, each fan, 20, 22, 25 is preferably adapted to be drivably rotatable in one rotational direction and each of the two fans is drivably rotatable in a rotational direction that is opposite the drivably rotatable direction of the other of the two fans.

Alternatively, in other embodiments, the resistance apparatus can comprise a pair of fans 10, 22 as shown in FIGS. 1-10 and additionally an eddy current brake disk

An exercise apparatus 5 according to the invention includes a user input device 5i such as a handle or a rotatable disc 30r that is readily manually engageable by a human being user via manual engagement of some selected portion of the user's body such the user's hands or feet with the engagement element 5e of the input device 5i. A unitary or single piece member means a single or unitary structural element. In some embodiments the user input device 5i comprises a single piece or a unitary member. A unitary or single piece member means a single or unitary structural element such as a single piece or unitary lever or arm 30, FIGS. 1, 1A, 4, 4A, 7, 8A, 8B, 9A, 9B that is driven by the user in both generally opposite directions 6f and 6o. Similarly a unitary or single piece member is disc or pulley, FIG. 5, 5A that is driven by the user in generally opposite directions 6f, 6o and is drivably connected to the mechanism that drives both fans 20, 22, such as axles 24, 24s, 24t that drive(s) both fans 20, 22. Similarly, pulley or gear 23 that is driven by the user's exertion of force in both generally opposite directions and also drives both fans 20, 22 is another example of a unitary or single piece member. Alternatively, the user input device could comprise a disc 30r that the user might typically engage with the user's feet.

The input device 5i is mechanically or manually movable in at least a first direction 6f and in a second direction 6o that is generally opposite in direction to the first direction 6f.

In embodiments where the resistance apparatus comprises at least two fans 20, 22, the fans are interconnected to the force input device 5i and are adapted such that only one of the two fans 20 is driven by movement of the input device 5i in one direction or a first direction 6f and the other one 22 of the two fans 20, 22 is driven by movement of the input device 5i in only one direction, the opposite direction 6o. As shown for example in FIG. 1A, when the user input device 5e of an exercise apparatus 5a or 5b is driven in a first or forward direction 6f by a forward force 6p, only one fan 22 of the two fans 20, 22 is driven in only one rotational direction, as shown in a counterclockwise direction 22cc. The other fan 20 of the two fans 20, 22 is not rotatably driven on account of a one way clutch or one way rotational direction hub 26cc to which the drive shaft 24 is interconnected. Thus the forward driving force exerted by a user on member 5e to effect driven movement 6f by user exerted force 6p of the manually engaged member 5e is resisted in only one direction R2 by the fan or fan 22 that rotates in the first direction 22cc.

Conversely as shown in FIG. 1B when the user input device 5e of an exercise apparatus 5a or 5b is driven in a second or reverse or opposite direction 6o only the other one fan 20 of the two fans 20, 22 is driven in only the one opposite rotational direction by a user exerted force 6t, as shown in a clockwise direction 20c. The other fan 22 of the two fans 20, 22 similarly is not rotatably driven on account of a one way clutch or one way rotational direction hub 26c to which the drive shaft 24 is interconnected. Thus the second, reverse or opposite driving force 6t exerted by a user on member 5e to effect driven movement 6o of the manually engaged member 5e is resisted in only one direction R1 by the one fan or fan 20 that rotates in the opposite direction 20c.

The two fans can be mounted on a single common axle 24 or, as shown in FIG. 1A, on separate axles 24s, 24t. In either configuration whether mounted on the same axle as in FIG. 1 or on different drive axles FIG. 1A, the fans 20, 22 are drivably interconnected 7, 7a, 7b and mounted to the axles 24, 24s, 24t via hubs 26, 26c, 26cc, 26r that are adapted and configures such that only one of the two fans 20 is rotatably driven 6fr, 26c by movement of the input device 5i in the first direction 6f and only the other one 22 of the two fans 20, 22 is driven 6or, 26cc by movement of the input device 5i in the opposite direction 6o.

In embodiments where the resistance apparatus comprises at least two fans 20, 22 that are mounted on a common axle, the fans 20, 22 are each mounted on the common drive axle 24 via a one way rotational direction bearings or hubs 26c, 26cc in an arrangement where the one way hubs 26c, 26cc are mounted to the common drive axle 24 such that the fans 20, 22 are limited to drivable rotation 20c, 22cc in a rotational direction that is opposite to each other, namely one fan 20 is drivable solely in a clockwise direction 26c relative to the other fan 22 which is drivable solely in a counterclockwise direction 26cc relative to the fan 20.

As shown in FIG. 1A when the user input device 5i is driven or moved in one direction, such as a forward direction 6f with user exerted force 6p, the interconnection of the input device 5i to the fans 20, 22 is adapted such that only one fan 22 of the two fans 20, 22 is driven and drivable in only one rotational direction 22cc with the other one fan 20 of the two fans not being rotatably drivable or driven at all. Conversely as shown in FIG. 1B when the user input device 5i is driven or moved in a rearward or opposite direction 6o relative to the direction of drive shown in FIG. 1A, the other fan 20 of the two fans 20, 22 is adapted to be driven and drivable in only one rotational direction 20c with the fan 22 of the two fans 20, 22 not being rotatably drivable or driven.

FIGS. 1, 1A, 1B show generic exercise apparatuses 5a, 5b that each have a force input device 5i interconnected to an engagement device 5e that a user can readily manually engage with a selected amount of force 6p, 6t to drive the input device 5i to move in a first direction 6f or a generally opposite direction 6o. As shown, FIGS. 1, 1A the input device 5i of apparatus 5a, can be comprised of a single piece or unitary lever 30 that moves or travels along a first path of travel 6fa beginning from a first position 5f in the first direction 6f to a second position 5s. Conversely the input device 5i moves or travels along a second path of travel 6oa beginning from the second position 5s in the second direction 6o to the first position 5f. The input device 5i need only travel in generally opposite directions 6f, 6o and the paths of travel 6fa, 6oa of the input device 5i need not necessarily be configured such that the device 5i starts in a single start position 5f or travel to a single second position 5s. The first and second paths of travel 6fa, 6oa are determined solely by mechanical directional movement of the input device 5i along paths of any selected length or degree of arc or rotation in generally opposite directions 6f, 6o without the input device necessarily having a single start 5f or end 5s position.

FIGS. 1, 1A, 1B show schematically for purposes of explanation, an apparatus 5 that has one or the other two alternative user input subassemblies 5a, 5b that include a mechanical assembly that acts as the input device 5i such as a lever 5e, 30 shown in apparatus 5a that pivots to travel either forwardly along an arcuate back and forth path of travel 6fa, 6oa, the path of travel of the manual engagement device 5e travelling along the same path in both directions 6f and 6o. Similarly with the alternative user input subassembly 5b, the manual engagement device 5e can be rotated in either a clockwise 6f or an opposite 6o counterclockwise direction, the engagement device 5e rotationally travelling along the same rotational path of travel in the first direction 6f as the engagement device 5e travels in the opposite direction 6o path of travel.

In alternative embodiments such as shown in FIG. 1AA the apparatus 5c can comprise an input device 5i and manual engagement member 5e that are configured such that the manual engagement member 5e does not travel along the same path of travel in both directions 6fa, 6oa but rather along different paths of travel when travelling in opposite directions 6f, 6o. For example, as shown in FIG. 1AA, the manual engagement device 5e travels from a start position 5ef in a first direction 6f along a first path of travel 6fa to a second position 5es and then travels back in a second opposite direction 6o along a second path of travel 6oa that is different from the first path of travel 6fa. As shown the manual engagement device 5e is interconnected to a user input device 5i that is interconnected to a resistance apparatus as described herein. The apparatus 5c can comprise, for example, an elliptical cross trainer or stride machine where the manual engagement device 5e is a foot pedal that travels along an elliptical back to front 6fa and front to back 6oa overall path of travel, the input device 5i being interconnected to a resistance apparatus as described herein such as one or more disks 25 of an eddy current brake apparatus or one or more fans 20, 22 as described herein that are interconnected to one way rotation devices or clutches. As with exercise apparatuses having specific configurations such as described with reference to FIGS. 4-10, an elliptical stride exercise apparatus 5c, FIG. 1AA could employ a single eddy current brake or a single fan as a source of resistance to movement in either direction 6f or 6o along either path of travel 6fa, 6oa.

FIGS. 2, 2A, 2B, 2C illustrate embodiments where the two fans 20, 22 are separately 7a, 7b mounted on separate shafts 24s, 24t via one way clutch hubs 26, 26c, 26cc that enables one of the fans 20, 22 to be drivable in only one direction 20c, 20cc or 22c, 22cc in response to forward 6f or rearward 60o directional drive of the manually engageable member 5e of an apparatus 5c, 5d. As shown, in FIGS. 2A, 2B, 2C when an input device 5i is driven in one forward direction 6f only one 22 of the two resistance fans 20, 22 is driven in one clockwise direction 22c while the other of the two fans 20 is prevented from being driven in a clockwise direction by a one way clutch 26c. Conversely as shown, when an input device 5i is driven in an opposite rearward direction 6o only the other one 20 of the two fans 20, 22 is driven in one counterclockwise direction 20cc while the other fan 22 is prevented from being driven in a counterclockwise direction by a one way clutch 26cc. Thus upon any given movement of the input device 5i either forward 6f or backward 6o, only one of the two fans 20, 22, 25 are rotatably driven and are driven and drivable in only one rotational direction. For example, with reference to FIG. 2C when an input device 5c, 5d is driven in one direction 6f only fan 22 is driven in a clockwise direction 22c while fan 20 is prevented from rotating in a clockwise direction by one way clutch 26c. Conversely when an input device 5c, 5d is driven in an opposite direction 6o only fan 20 is driven in a counterclockwise direction 20cc while fan 22 is prevented from rotating in a counterclockwise direction by one way clutch 26cc.

FIG. 3 shows one example of a one way rotation direction clutch, bearing or hubs 26 in which rollers 27 are received within a receiving aperture 27a disposed between the inner race (axle) 27ri and the outer race 27ro of the clutch bearing or hub 26. As shown the rollers 27 do not lockably engage the inner surface of the outer race 27ro and freely roll along the outer surface 27ris of the inner race when the inner race or hub 24 rotates in the 26c1 rotational direction as shown. In this direction of rotation therefore, the shaft 24 does not drive the fan 20 (FIG. 1) that is snug or force fit engaged with the outer surface 27ros of the outer race 27ro. Conversely when the axle or shaft 24 is rotated is the opposite direction 26cs, the balls 27 engage and lock against and between the inner surface 27rois of the outer race 27ro and the outer surface 27ris of the inner race 24, 27ri thus causing the fan 20 to be driven together with the axle 24, 27ri in the 27cs rotational direction. Thus when the outer race surface 27ros of a clutch bearing 26, in 26c, or 26cc (FIG. 1) is mounted in compressed, typically force fit, engagement with the inner surface 20is of the hub of a fan 20, 22, 25, the fan will be driven by a rotatably driven axle 24 that is being driven in the roller 27 locked or engaged direction 26cs. As discussed with reference to FIGS. 1, 1A, 2, the one-way clutches, bearings or hubs 26c, 26cc are arranged and mounted on axle 24 such that the outer race 27ro of one clutch 26c locks to cause fan 20 to drivably rotate when the shaft 24 is rotated in one rotational direction and the outer race 27ro of the other clutch 26cc locks to cause fan 22 to drivably rotate when the shaft 24 is rotated in the opposite rotational direction.

FIGS. 4, 4A show a back extension or abdominal muscle exercise apparatus 5 comprising a frame 12, a seat 16 having a forward edge 16f, a rearward edge 16r, and a generally planar seating surface (PS), a foot rest 12f disposed forwardly of and below the seating surface PS and a pelvic stabilization pad 18 having a lower back engagement surface (ES) disposed at the rearward edge 16r of the seat, a user input device 5i mounted to the frame for movement in a first direction FD, 6f along a first path of travel 6fa and for movement in a second direction 6o that is opposite the first direction along a second path of travel 6oa. The user input device 5i, typically comprised of a single piece or unitary lever 30, is interconnected to a resistance apparatus 10 via an intermediate interconnection to a cam device 17 that has a cammed surface 17s that can control and vary the speed or rate of rotation of the resistance fans 20, 22 according to a predetermined profile 17s of the cammed surface 17s. The profile 17s can be adapted to vary the speed of movement of the resistance device non linearly or in a non linear relationship relative to the speed of movement of the input device 5i. The cam mechanism 17 is interconnected to the user input device 5i in an arrangement such that the cam mechanism is movably driven or translated in a first direction 17f together with movement in the first direction 6f of the input device 5i and movably driven or translated in a second opposite direction 17o together with movement in the opposite direction 6o of the input device 5i.

The resistance apparatus 10 of the FIG. 4, 4A embodiment exerts a first resistance R1 to movement of the user input device in the first direction 6f or along the first path of travel 6fa and exerts a second resistance R2 to movement of the user input device in the second direction 6o or along the second path of travel 6oa. The seating surface PS is disposed at an angle SA relative to horizontal such that the rearward edge 16r is disposed horizontally above the forward edge 16f and such that a human being user can sit in a forward facing direction FW on the angled seating surface PS, simultaneously engage the user's foot on the foot rest 12f while pushing the user's lower back along the angled seating surface PS into engagement with the lower back engagement surface ES by extending the user's legs. Such engagement of the user's lower back with the stabilization pad 18 and engagement surface ES while under the force of the user's forcible extension of the user's legs thus forcing the user's lower back into compressed engagement with the stabilization pad 18 surface ES enables stabilizes the user's pelvis against twisting or lateral turning as well as against front to back movement while the user is performing an exercise.

The user input device 5i of the FIGS. 4, 4A embodiment includes an engagement device 5e and is arranged on the frame 12 relative to the seating surface PS such that the user can manually engage ME the engagement device 5e when seated on the angled seating surface PS with the user's lower back engaged against the lower back engagement surface ES of the pelvic stabilization pad 18. The arrangement of the engagement device 5e relative to the angled SA seat 16 thus requires the user to exercise the user's abdominal muscles in order to exert first FF and second SF selected amounts of force respectively to manually drive the user input device 5i against the first and second resistances R1, R2 respectively which causes the user input device 5i to travel in the first 6f and second 6o directions respectively. As shown in FIGS. 4, 4A, the input device 5i is drivably interconnected via pulleys 5p, belts and chains 5z to an intermediate drive axle 23a that is interconnected via a pulley 23 and belt 23b to the drive axle 24. The drive axle 24 drives a dual fan resistance subassembly 10 as described above preferably an assembly comprised of two fans as shown in FIGS. 1, 2, 3, 3A that are mounted on one way rotation direction bearings such that the first resistance R1 is exerted solely by one of the fans 20, 22 and the second resistance R2 is exerted solely by the other of the fans. An eddy current brake disk 25 can be included to exert a selectable amount of resistance in addition to whatever resistance that fans 20, 22 exert to movement of the input device 5i in the first 6f and second opposite 6o directions under the selected amounts of force FF, SF exerted by the user.

FIGS. 5A and 6 show a torso rotation exercise apparatus comprising a frame 12, a user input device 5i mounted on the frame 12 having an engagement device 5e comprised of a rotatable foot stand 5fs or rotatable arm assembly 5as adapted to receive and engage a selected portion of a user's torso such as the user's feet on the surface of the foot pedal 5fs. The user input device 5i comprised of a single piece or unitary pulley 30r is adapted to rotate UR in a first direction 6f along a first path of travel 6fa and in a second direction 6o that is opposite the first direction along a second path of travel 6oa, the first direction and first path of travel comprising clockwise rotation of the user input device along a clockwise arc, the second direction and second path of travel comprising counterclockwise rotation of the user input device along a counterclockwise arc. The user input device 5i is interconnected to a resistance apparatus 10 via a series of pulleys, belts and the like 10i. The resistance apparatus 10 exerts a first resistance R1 to user exerted force FF to cause movement of the user input device in the first direction 6f or along the first path of travel 6fa and exerts a second resistance R2 to the user force to cause movement of the user input device in the second opposite direction 6o or along the second path of travel 6oa. The engagement device 5e is readily engageable with a portion of the user's torso such as a foot or hand or arm. As shown, the apparatus 5 includes one or more upper torso engageable pads 5x and handles 5xe that a user who is standing upright on foot receiving pedal surfaces 5fs can engages with their back or chest or shoulders, 5x or with their hands 5xe to facilitate the user's performing a torso rotation exercise UR while standing upright.

As shown in the FIGS. 5A, 5B embodiment, a user's feet UF are placed onto an upper facing surface 5fs of the pedals 5e of the input device 5i. Once the user is standing with feet on the surfaces 5fs, the user exerts exercise force 6p to forcibly rotate UR the input device 5i in one direction to cause one of the two fans 20 to exert resistance R1 against the user force 6p. Conversely the user exerts a force in the opposite direction 6t to forcibly rotate UR the input device 5i in an opposite direction to cause the other of the two fans 22 to exert a second resistance R2. As shown, the user input device 5i is interconnected to a drive pulley 30r that is in turn interconnected to the two fans in the same or similar manner as described above with reference to FIGS. 1, 1A, 1B, 2A, 2B, 2C, 3.

In the FIG. 6 embodiment, the engagement device is a padded arm or hand engagement arm that is mounted via a linkage 5I to an overhead axle or hub 5ir that is rotatable around axis A. The user input device 5i is thus rotatably drivable around axis A in first and second directions along first and second paths of travel against first and second resistances exerted by fans 20, 22 in response to a user's engaging the engagement device's padded arms 5e and using selected upper torso muscles to exert force UR to rotate the user's upper torso while the user maintains engagement with the engagement device 5e. The input device 5i is drivably interconnected via gears, pulleys, belts, chains and the like 10i to an intermediate drive axle 23a that is interconnected via a pulley 23 and belt to the drive axle 24 on which fans 20, 22 are drivably mounted. The drive axle 24 drives a dual fan resistance subassembly 10 as described above preferably an assembly comprised of two fans as shown in FIGS. 1, 2, 3, 3A that are mounted on one way rotation direction bearings such that the first resistance R1 is exerted solely by one of the fans 20, 22 and the second resistance R2 is exerted solely by the other of the fans. An eddy current brake disk 25 can be included to exert a selectable amount of resistance in addition to whatever resistance that fans 20, 22 exert to movement of the input device 5i in the first 6f and second opposite 6o directions under the selected amounts of force FF, SF exerted by the user.

FIG. 7 shows a chest and rowing exercise apparatus 5 comprised of a frame 12 on which is mounted a foot rest 12f and a seat 16 that are mounted on the frame in an arrangement to enable a user's sitting on the seat 16 with the user's foot engaged with the foot rest 12f in performance of a row or chest exercise. The seating surface PS is disposed at an angle SA relative to horizontal such that the rearward edge 16r is disposed horizontally above the forward edge 16f and such that a human being user can sit in a forward facing direction FW on the angled seating surface PS, simultaneously engage the user's foot on the foot rest 12f and push the user's lower back along the angled seating surface PS into engagement with the lower back engagement surface ES by extending the user's legs. Such engagement of the user's lower back with the stabilization pad 18 and engagement surface ES while under the force of the user's forcible extension of the user's legs forcing the user's lower back into compressed engagement with the stabilization pad 18 surface ES enables the user to thus stabilize the user's pelvis while performing an exercise.
