EXERCISE DEVICE

FIELD OF THE INVENTION

[01] The present invention relates, in general, to an exercise device and a method of using the same. More particularly, the present invention relates to an exercise device and method wherein the exerciser exerts muscle force against an adjustable portion of the exerciser's own body weight, and other methods described herein.

BACKGROUND OF THE INVENTION

[02] Home exercise is becoming increasingly more popular. Home exercise offers the health benefits of regular exercise while recognizing that many people have difficulty in finding sufficient time in their schedule for a full workout at a health club or gymnasium. An exerciser may exercise at home whenever the exerciser's schedule permits. This flexibility in scheduling often allows for a more consistent and thus healthful exercise regime.

[03] Home exercise, however, has its drawbacks. In particular, in order to exercise all or most of the muscle groups, multiple pieces of home exercise equipment may be required. Furthermore, these multiple pieces of equipment may require permanent installation in the exerciser's home.

[04] Permanent or not, many popular pieces of home exercise equipment occupy a great deal of space. This makes the use of this equipment impractical in homes or apartments which do not have the required extra space. Furthermore, non-permanent pieces of equipment are often difficult to disassemble and may require much storage space even when disassembled. A user must then often choose between an exercise device providing a complete exercise regime and a device which fits the exerciser's home space.

[05] There is, thus, a need for exercise equipment which may be easily stored when not in use, does not occupy a great deal of space when in use and provides for exercising all or most of the muscle groups.

[06] Exercise devices are known in which a user, positioned on a support platform, propels that support platform up an inclined ramp. One way by which the platform may be propelled is by pulling a cable connected to the support platform through a variety of pulleys positioned on the exercise device. By changing positions on the platform and by changing the method by which the platform is propelled, a user can exercise multiple muscle groups.

[07] While early versions of these devices did not allow for easy storage, later designs were proposed that allowed for some type of disassembly in the design. Even the later designs do not,

however, provide complete foldability of the exercise unit. The designs include some separate elements which must be disengaged to allow for foldability of the device. Thus, these designs cannot be folded and stored as a unit. Moreover, the designs are not easily converted from the folded stored state to an unfolded state for use.

[08] Another problem with early versions of these devices is that they did not allow for a wide variety of different types of muscle exercises, especially multiple muscle exercises for each specific muscle group.

[09] In view of the foregoing, there is a need for an inclined ramp exercise device which is easily foldable to a size which allows for easy storage, is easily unfolded into a useable state, and which allows for exercising multiple muscle groups and multiple exercises for each muscle group.

[10] There is also a need for multiple exercises, sequences of exercises, instruction, and education related to an inclined ramp exercise device.

[11] In the inclined ramp exercise device, a user can make the workout more difficult by increasing the angle and height of the inclined ramp on which the platform is propelled. In the past, this was manually performed by the user by lifting one end of an inclined ramp and setting the inclined ramp at a desired height and angle of inclination for the desired level of difficulty .

A user may have to lift and reset the inclined ramp multiple times, depending on which exercises the user is performing and the desired resistance level. This can be tiring and cumbersome.

[12] Thus, a need also exist for an inclined ramp exercise device and a method where the exercise device includes an automatic lift mechanism for automatically setting the height and angle of the inclined ramp.

[13] Alternatively, in circumstances where a consumer can not justify the additional cost of an automatic lift mechanism (e.g., , such as, but not limited to home gym use), a need exists for a lift-assist mechanism to assist the user in lifting the inclined ramp and setting the inclined ramp at a desired height and angle of inclination for the desired level of difficulty .

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[64] With reference to FIGS. 1-3, a collapsible exercise device 100 constructed in accordance with an embodiment of the invention will now be described. The collapsible exercise device 100 is shown in an unfolded state. The collapsible exercise device 100 includes a vertical support member or tower 110 having a base 120 and a tower housing 130. The base 120 includes a pair of opposite foot-shaped base members 140 joined by an intermediate base section 150. The

tower housing 130 extends from the intermediate base section 150 of the base 120. The tower housing 130 includes a front vertical face 160, a rear vertical face 170, and opposite symmetric sides 180. The sides 180 include tower level tracks 190 with multiple tower level hooks 200 evenly vertically spaced along the tracks 190.

[65] Slide bars 210 extend inwardly from proximal ends 220 of a pair of upper rails 230. The inwardly extending slide bars 210 may be slid up or down in the tower level tracks 190 and set in corresponding tower level hooks 200 to a desired height. The slide bars 210 may be removable from the upper rails 230. A pair of lower rails 240 are pivotally connected to the upper rails 230 at rail pivot points 250. A strut 260 is pivotally connected to the base 120 through a lower pivot bar 270 at the base members 140 and is also pivotally connected to the rail pivot points 250 through an upper pivot bar 280. The strut 260 includes an upper strut post 290 matingly received within a lower strut post 300. The strut posts 290 may be locked with respect to each other with a spring-loaded pull pin 310 and lateral holes in the upper strut post 290. [66] In an alternate embodiment, one end of the strut 260 may be pivotally connected to the upper pivot bar 280, while the other end includes a support platform that rests on a floor. [67] A user support platform 320 is slidably attached to the rails 230, 240 through support frame or glideboard 330 and rollers (not shown) on the support frame 330. A main support pad 340 is attached to and supported by the support frame 330. A bumper (not shown) may be positioned on the lower rails 240 to prevent the user support platform 320 from rolling all the way down the lower rails 240.

[68] With reference to FIGS. 1, 2, and 4A-5B, a telescoping squat stand 350 and folding squat platform 360 constructed in accordance with an embodiment of the invention will be described. In FIGS. 4A and 4B, the folding squat platform 360 is shown in an unfolded state with the telescoping squat stand 350 removed from the folding squat platform 360. The folding squat platform 360 includes opposite parallel rails 370 joined by perpendicularly extending cross rail 380. Each rail 370 has a generally square cross-section and includes a short, straight pivot portion 385, a curved portion 390, and an elongated distal portion 400. The pivot portion 380 carries a spring-loaded pull pin 410 for locking the folding squat platform 360 within pin holes 415 near a distal end 420 of the lower rails 240. A spring-loaded depressible pin 430 is carried in the elongated distal portion 400 for locking the folding squat platform 360 in place along the folding squat platform 360.

[69] In the unfolded state shown in FIGS. 4A and 4B, the curved portion 390 of the rails 370 and the cross rail 380 are supported by a cross member 440. The cross member 440 has a generally cylindrical configuration and extends perpendicularly between the distal ends 420 of the lower rails, joining the lower rails 240. Ends 450 of the cross member 440 extend laterally beyond the distal ends 420 and may carry rollers or wheels for rolling this part of the exercise device 100 along the floor.

[70] The folding squat platform 360 may be pivoted or folded up to the compact position shown in FIGS. 5 A and 5B, where the elongated distal portion 400 of the folding squat platform 260 is generally parallel with the lower rails 240. The telescoping squat stand 350 includes opposite straight parallel rails 460, perpendicularly extending supports 470, and a squat platform 480 supported by and connected to the rails 460 and supports 470. The rails 460 include a generally square cross-sectional, hollow configuration and telescope onto (matingly receive) the elongated distal portions 400 of the rails 370. When attaching the squat stand 350 to the rails 370, the pins 430 may be depressed slightly to allow the rails 460 to slide completely onto the rails 370. Each rail 460 may include one or more pin holes 490 that the spring-loaded pin 430 snap locks into when the hole 490 is over the pin 430. The telescoping squat stand 350 may be removed by pressing down on the pins 430 and sliding the rails 460 of the squat stand 350 off of the rails 370 of the folding squat platform 360. The folding squat platform 360 (or the folding squat platform 260 and connected squat stand 350) may be removed from the distal ends of the lower rails 240 by pulling the pull pins 410 out of the pin holes 415 and removing the folding squat platform 360 from the lower rails 240.

[71] FIGS. 5C and 5D illustrate an embodiment of a telescoping toe bar accessory 501 that attaches to the folding platform 360 in the same manner as the telescoping squat stand 350. The toe bar accessory 501 includes opposite straight parallel rails 502, perpendicularly extending toe bar 503, and a cylindrical toe pad or cushion 504 that surrounds a central portion of the toe bar 503. The rails 502 include a generally square cross-sectional, hollow configuration and telescope onto (matingly receive) the elongated distal portions 400 of the rails 370. When attaching the toe bar accessory 501 to the rails 370, the pins 430 may be depressed slightly to allow the rails 502 to slide completely onto the rails 370. Each rail 502 may include one or more pin holes 505 that the spring-loaded pin 430 snap locks into when the hole 505 is over the pin 430. The telescoping toe bar accessory 501 may be removed by pressing down on the pins 430

and sliding the rails 502 of the toe bar accessory 501 off of the rails 370 of the folding platform

360. The folding platform 360 (or the folding platform 260 and connected toe bar accessory 501) may be removed from the distal ends of the lower rails 240 by pulling the pull pins 410 out of the pin holes 415 and removing the folding platform 360 from the lower rails 240. [72] With reference to FIG. 6A, an embodiment of a push-up bar accessory 500 that may be easily attached to and removed from the distal ends 420 of the lower rails 240 will now be described. The push-up bar accessory 500 includes a pair of opposite coupling brackets 510 for connecting the push-up bar accessory 500 to the distal ends 420 of the lower rails 240. A pushup bar 520 includes handles 530 with grips 540, upwardly angled portions 550, and intermediate portion 560. The push-up bar 520 is connected to the brackets 510 near where the intermediate portion 560 joins the angled portions 550. The brackets 510 carry spring-loaded pull pins 570 for attaching the push-up bar accessory 500 to and removing it from pin holes 415 at the distal ends 420 of the lower rails 240.

[73] With reference to FIGS. 7A and 7B, an embodiment of a padded foot support accessory 580 that may be easily attached to and removed from the distal ends 420 of the lower rails 240 will now be described. The padded foot support accessory 580 includes a foot pad 590 supported by and connected to opposite brackets 600 for connecting the padded foot support accessory 580 to the distal ends 420 of the lower rails 240. The brackets 600 carry spring-loaded pull pins 610 for attaching the padded foot support accessory 580 to and removing it from pin holes 415 at the distal ends 420 of the lower rails 240. In the position shown, the padded foot support accessory 580 is supported by the brackets 600 on the lower rails 240 and the cross member 440.

[74] With reference to FIGS. 8A-9B, an embodiment of a dip bar accessory 620 that may be used with the exercise device 100 will now be described. The dip bar accessory 620 includes handles 630 with grips 640 attached at ends 650 to perpendicularly extending cross rails 660. The handles 630 may have a generally cylindrical, tubular configuration and the cross rails 660 may have a generally square cross-sectional, hollow configuration. The cross rails 660 slide laterally in and out within brackets 670 mounted to the lower rails 240. The brackets 670 have rectilinear cut outs 680 that the cross rails 660 slide within. A locking mechanism (not shown) of the brackets 670 (or as one or more separate members) allow the handles 630 to be moved laterally outward and rotated 90 degrees upward to the unretracted state shown in FIGS. 8 A and

8B, and moved laterally inward and rotated 90 degrees downward to the retracted state shown in

FIGS. 9A and 9B. In the unretracted, active state shown in FIGS. 8A and 8B, the cross rails 660 are low enough and the handles 630 are disposed laterally outward far enough so as to avoid contact with the support frame 330 of the user support platform 320 when the platform 320 is in motion. In the retracted state shown in FIGS. 9A and 9B, the handles 630 are disposed beneath and parallel to the lower rails 240. In this position, the handles 630 are also are disposed laterally inward far enough so as to avoid contact with the support frame 330 of the user support platform 320 when the platform 320 is in motion.

[75 ] With reference to FIGS . 1 OA- 11 B , an embodiment of a folding foot platform 700 that may positioned in an unretracted or unfolded state (FIGS. 1OA, 10B) and a retracted or folded state (FIGS. 1 IA, HB) will now be described. The folding foot platform 700 includes a generally Y-shaped member 710 telescoped within an upside-down generally T-shaped member 720. The generally Y-shaped member includes a cylindrical main insertion tube 730 and upwardly angled foot retaining tubes 740. Cylindrical toe cushions 750 cover the upwardly angled foot retaining tubes 740. The upside-down generally T-shaped member 720 includes a main receiving tube 760 and outwardly perpendicularly extending cylindrical heel support tubes 770. Cylindrical heel cushions 780 cover the heel support tubes 770. The main insertion tube 730 is slidably received within the main receiving tube 760 and may be locked relative thereto with a pull pin within holes in the tubes 730, 760. Outer lateral ends of the heel support tubes 770 are fixedly connected to pivoting brackets 790. The pivoting brackets 790 are pivotally connected to inner sides 800 of the upper rails 230 through pivot pins 810. In the unretracted state shown in FIGS. 1OA, 1OB, a user may position his or her feet into the folding foot platform 700 by putting toes underneath the toe cushions 750 and heels on the heel cushions 780. The brackets 790, and, hence, the folding foot platform 700, are prevented from pivoting farther upward than the state shown in FIGS. 1OA and 1OB by an upper flange 820 of the upper rails 230. When not in use, the folding foot platform 700 may be pivoted or folded to an out-of-the- way, retracted or folded state shown in FIGS. 1 IA, 1 IB.

[76] With reference to FIGS. 1, 12A, and 12B, an embodiment of folding, combination pulley- support and pull-up bars 830 will now be described. In the embodiment shown, each bar 830 has a trapezoidal configuration and includes the following main sections: a short, straight, proximal tubular section 840, a straight, distal tubular section or pull-up handle 850 parallel to and longer

than the proximal tubular section 840, an elongated, straight, angled, outer tubular section 860, and an elongated, straight, inner tubular section 870 perpendicular to the proximal tubular section 840 and the distal tubular section 850. An outer end of the proximal tubular section 840 is connected to a proximal end of the outer tubular section 860 by a tubular proximal outer elbow 880. An outer end of the distal tubular section 850 is connected to a distal end of the outer tubular section 860 by a tubular distal outer elbow 890. An inner end of the distal tubular section 850 is connected to a distal end of the inner tubular section 870 by a tubular distal inner elbow 900. An inner end of the proximal tubular section 840 is connected to a proximal end of the inner tubular section 870 by a pivoting bracket 910. The pivoting bracket 910 is pivotally connected to an attachment bracket 920, which is attached to the proximal end 220 of the upper rails 230. The pivoting bracket 910 carries a spring-loaded pull pin 930. The attachment bracket 920 may include a vertical pin hole, a horizontal pin hole, and a collapsing pin hole. [77] For normal use, the bars 830 may be moved to the position shown in FIG. 1 and locked into place using the pull pin 930 and the vertical pin hole on the attachment bracket 920. For performing chin ups, the bars 830 may be moved to the position shown in FIGS. 12A, 12B and locked into place using the pull pin 930 and the horizontal pin hole on the attachment bracket 920. For collapsing the exercise device 100, the bars 830 may be moved to the position shown in FIG. 13, where the bars 830 are parallel to the upper rails 230 and locked into place using the pull pin 930 and the collapsing pin hole on the attachment bracket 920.

[78] Pulleys 940 are slidably attached to the bars 830. Each pulley 940 includes a collar 950 and a spring-loaded pull pin 960. An exerciser may move each pulley 940 to a desired position on the bar 830 by pulling on the pull pin 960, sliding the pulley 940 via the collar 950 to a desired position on the bar 830, and releasing the pull pin 960 to lock the pulley 940 in place on the bar 830. It should be noted, the pulley 940 may be slid onto sections or elbows other than the inner tubular section 870.

[79] A connector extends through the pulleys 940 and connects to the user support platform 320. The connector may be of any suitable well-known type, but shown by way of example 1 is a cable 970. The cable 970 includes handles 980 (connected via links 990) at each end and extends through the pulleys 940 positioned on the combination pulley-support and pull-up bars 830 and loops through a third pulley 1000 attached to the user support platform 320. The third pulley 1000 is positioned along the lateral centerline of the user support platform 320. This

position allows for unilateral (i.e. one arm), bilateral (i.e., two arm) and static equilibrium (i.e. holding the user support platform 320 suspended by keeping a constant force on each handle 980) use.

[80] The cable 970 and the handles 980 may hang from attachment member 1002 (FIG. 4A) when not in use for storage purposes. The attachment member 1002 may also be used for connecting a separate pulley and leg ankle cuff.

[81] The cable 970 should preferably be of sufficient length to extend through the pulleys 940 and allow the exerciser to grasp one or both of the handles 980 while the exerciser is on the user support platform 320 and the user support platform 320 is at rest.

[82] In an alternate embodiment, the connector may be two separate cables extending through the pulleys 940 with each cable fixedly attached to the user support platform 320. [83] With reference to FIGS. 13 and 14, the collapsible or foldable nature of the exercise device 100 will now be described. FIG. 13 shows the collapsible exercise device 100 in a semi- folded state. The slide bars 210 at the proximal ends 220 of the upper rails 230 are lowered to the bottom of the tower level tracks 190 of the vertical support tower 110, and the squat stand 350 is folded over onto the user support platform 320. The rail pivot points 250 and the upper pivot bar 280 are then drawn up away from the floor while rollers on the cross member 440 roll along the floor. The exercise device 100 continues to be folded until the vertical support tower 110, the strut 260, the upper rails 230, the lower rails 240, the user support platform 320, the squat stand 350, and the combination pulley-support and pull-up bars 830 are substantially parallel as shown in FIG. 14. It should be noted that in this position, the user support platform 320 may be rolled up the lower rails 240 and off of the collapsed exercise device 100. To unfold the exercise device 100, the rollers on the cross member 440 at distal ends 420 of the lower rails 240 are rolled along the floor away from the vertical support tower 110. Once the upper rails 230 and the lower rails 240 are extended along the floor 52, the slide bars 210 at the proximal ends 220 of the upper rails 230 are raised via the proximal ends 220 of the upper rails 230 just above a desired height and lowered into tower level hooks 200 at the desired height. The squat stand 350 may then be folded to the position shown in FIG. 1.

[84] In use, the exerciser positions himself or herself on the user support platform 320 and grasps one or both of the handles 980. The exerciser then draws one or both of the handles 980

toward the exerciser and by doing so transports the user support platform 320 up along the lower rails 240 and upper rails 230.

[85] By varying the height of the proximal ends 220 of the upper rails 230 on the tower level hooks 200 of the vertical support tower 110, the angle θ (shown in FIG. 2) may be adjusted. The adjustment of this angle θ alters the percentage of the exerciser's weight which the exerciser's muscles are moving. This allows for adjustment of the intensity of the exerciser's workout. Weight bars (not shown) may be added to the user support platform 320 so that weight plates (not shown) may be positioned on the weight bars, thus adding to the weight propelled by the exerciser's muscles.

[86] The exerciser may vary the position of the pulleys 940 on the combination pulley-support and pull-up bars 830 in the manner described above. For example, the pulleys 940 may be raised or lowered on the inner tubular sections 870 so that the handles 980 and pulling motion are at a more comfortable orientation or to work different muscle groups. The pulleys 940 may be moved to the outer tubular sections 860 (or other sections) for a wider grip and motion of the handles 980 or to work different muscle groups.

[87] An exerciser may also vary the resistance while working upper body muscles by positioning him or herself on the user support platform 320 with the exerciser's feet on the squat stand 350 or floor. The legs and lower body then provide assistance in moving the user support platform 320, lessening the load on the upper body muscles. The exerciser may also use the squat stand 350 to perform the squat exercise for the lower body muscles. [88] In an alternate embodiment, an exerciser may lie on the user support platform 320 with the exerciser's feet positioned in the foot platform 700 as described above. By bending the exerciser's legs, the exerciser draws the user support platform 320 up along the rails 230, 240. The exercise may also perform sit ups on the user support platform 320 by securing his or her legs in the foot platform 700. In this embodiment, the squat stand 350 and folding platform 260 may be replaced with the padded foot support accessory 580 to support the feet. [89] In a further embodiment, the squat stand 350 and folding platform 260 may be replaced with the push-up bar accessory 500. The exerciser performs push ups using the push-up bar accessory 500 with his or her feet on the floor, and the chest over the distal part of the lower rails 240. The exerciser may also lie on the user support platform 320 and use the push-up bar accessory 500 to perform a military press or similar exercise.

[90] In another embodiment, the exerciser may lie on the user support platform 320, grip the handles 630 of the dip bar accessory 620 (FIGS. 8A, 8B), and perform dips, exercising the arms and chest.

[91] Furthermore, an exerciser may lower the combination pulley-support and pull-up bars

830 to the position shown in FIGS. 12A, 12B as described above, position himself or herself on the user support platform 320, and grasp the handles 850. By drawing the exerciser toward the handles 850, the exerciser is exercising additional muscle groups.

[92] With reference to FIGS. 15-17, an alternative embodiment of an exercise device 1100 will now be described. The exercise device 1100 is similar to the exercise devices shown and described above with respect to FIGS. 1-14, except the exercise device 1100 includes an automatic lift mechanism 1110 (FIG. 17) to set the height and angle of the rails 230, 240 and user support platform 320. This eliminates the need for a user to manually set the height and angle of the rails 230, 240 and user support platform 320 by lifting or lowering the rails 230, 240 and user support platform 320, sliding the inwardly extending slide bars 210 up or down in the tower level tracks 190, and setting the bars 210 in corresponding tower level hooks 200 as described above with respect to FIGS. 1 and 2.

[93] The exercise device 1100 includes a tower 1120 with a tower housing 1130 extending from an intermediate base section 1140 of a base 1150. The tower housing 1130 includes a front vertical face 1160, a rear vertical face 1170, and opposite symmetric sides 1180. The sides 1180 include elongated vertical tracks 1190. Slide bars 1210 extend inwardly from proximal ends 220 of the upper rails 230. The inwardly extending slide bars 1210 are coupled to chains 1230 (FIG.

17) of the automatic lift mechanism 1110 through couplers 1240.

[94] With reference to FIG. 16, an inner frame assembly 1250 of the tower 1120 is shown.

The inner frame assembly 1250 includes the sides 1180 extending from the base 1150 and a horizontal cross support 1260 spanning the distance between the sides 1180 at a top of the frame assembly 1250. Near a bottom of the frame assembly, between the sides 1180, a driving mechanism 1270 (e.g. motor with attached power cord) of the automatic lift mechanism 1110 is disposed.

[95] With reference to FIG. 17, the automatic lift mechanism 1110 of the exercise device 1110 will be described in more detail. The automatic lift mechanism 1110 includes the opposite chains 1230, an upper pulley assembly 1280, and the driving mechanism 1270, which includes

lower pulleys 1290 and shafts 1300. The upper pulley assembly 1280 includes opposite pulleys

1310 and shaft 1320. In use, after the driving mechanism 1270 is plugged into a wall outlet, the automatic lift mechanism 1110 is actuated to raise or lower the height and angle of the rails 230, 240 and user support platform 320. This may be accomplished with a three-way toggle switch that may be set to an up or raise position for causing the driving mechanism 1270 to rotate in one direction to increase the height and angle of the rails 230, 240 and user support platform 320, may be set to an down or lower position for causing the driving mechanism 1270 to rotate in an opposite direction to decrease the height and angle of the rails 230, 240 and user support platform 320, and may be set to a third neutral position where the driving mechanism 1270 is off and the height and angle of the rails 230, 240 and user support platform 320 is locked in place. Varying the height and angle of the rails 230, 240 and user support platform 320 varies the portion of the exerciser's own body weight that the user exerts muscle force against during use of the exercise device 1100. The automatic lift mechanism 1110 eliminates the need for a user to manually set the height and angle of the rails 230, 240 and user support platform 320 by lifting or lowering the rails 230, 240 and user support platform 320, sliding the inwardly extending slide bars 210 up or down in the tower level tracks 190, and setting the bars 210 in corresponding tower level hooks 200 as described above with respect to FIGS. 1 and 2. [96] With reference to FIG. 18, an alternative embodiment of an exercise device 1400 will now be described. Elements of the exercise device 1400 that are similar to the elements described above with respect to exercise devices 100, 1100 will be described with like reference numbers. The exercise device 1400 is similar to the exercise devices shown and described above with respect to FIGS. 1-17, except the exercise device 1100 includes a non-motorized lift-assist mechanism 1410 to assist the user in setting the height and angle of the rails 230, 240 and user support platform 320. This assists the user and reduces the work required to manually set the height and angle of the rails 230, 240 and user support platform 320 when lifting or lowering the rails 230, 240 and user support platform 320, sliding the inwardly extending slide bars 210 up or down in the tower level tracks 190, and setting the bars 210 in corresponding tower level hooks 200 as described above with respect to FIGS. 1 and 2.

[97] Similar to the exercise device 100, the exercise device 1400 includes a strut 260 that is pivotally connected to the base 120 at one end and is pivotally connected to the rail pivot points 250 at an opposite end. The strut 260 includes an upper half 1420 and a lower half 1430. At

approximately a mid-point of the upper half 1420, a bottom end of the non-motorized lift-assist mechanism 1410 is pivotally attached to the strut 260 at pivot point 1440. An opposite end of the non-motorized lift-assist mechanism 1410 is pivotally attached to approximate mid-points of the upper rails 230 though a pivot bar 1450 similar to pivot bar 280 (FIG. 3) discussed above. In the embodiment shown, the non-motorized lift-assist mechanism 1410 is a push-type gas spring. In alternative embodiments, other types of non-motorized lift-assist mechanisms are used such as, but not by way of limitation, standard coil springs (extension and/or compression as needed). The push-type gas spring provides an upward angled force in the direction of the arrow shown, reducing the upward force and work required by a user when raising the height and increasing the angle of the upper rails 230 relative to the ground. This upward force also makes it easier to lower the height and reduce the angle of the upper rails 230 because it reduces the lifting work required of the user. In alternative embodiments, the non-motorized lift-assist mechanism 1410 is connected to the strut 260 and/or the rails 230, 240 at pivot points other than those shown and/or the non-motorized lift-assist mechanism 1410 is disposed at an angle other that that shown.

[98] FIG. 19 illustrates a further embodiment of an exercise device 1500. The exercise device 1500 is similar to the exercise device shown in FIG. 18, except an alternative embodiment of a non-motorized lift-assist mechanism 1510 is shown. Steve The non-motorized lift-assist mechanism 1510 includes a pull-type gas spring pivotally mounted between strut 260 at pivot point 1540 and lower rails 230 though a pivot bar (now shown). The pull-type gas spring provides a downward angled force in the direction of the arrow shown. This pulls on the lower rails 230 in the direction of the arrow, reducing the upward force and work required by a user when raising the height and increasing the angle of the upper rails 230 relative to the ground. This downward angled force also makes it easier to lower the height and reduce the angle of the upper rails 230 because it reduces the lifting work required of the user. In alternative embodiments, the non-motorized lift-assist mechanism 1510 is connected to the strut 260 and/or the rails 230, 240 at pivot points other than those shown and/or the non-motorized lift-assist mechanism 1510 is disposed at an angle other that that shown.

[99] FIGS. 20A-20D illustrate a still further embodiment of an exercise device 1600. The exercise device 1600 is similar to the exercise devices shown in FIGS. 18 and 19, except an alternative embodiment of a non-motorized lift-assist mechanism 1610 is shown. Instead of the

non-motorized lift-assist mechanism being incorporated between the strut 260 and the rails 230,

240, the non-motorized lift-assist mechanism 1610 is incorporated within the tower 110. The non-motorized lift-assist mechanism 1610 includes a pull-type gas spring 1620, a tension shaft 1630, a lower pulley assembly 1640, an upper pulley assembly 1650, a top shaft 1660, pulley belt arrangement 1670, a cable 1680, and a rail shaft 1690. The pull-type gas spring 1620 is mounted at a bottom end of the base 120. At an opposite end, the pull-type gas spring 1620 is connected to the lower pulley assembly 1640 through the tension shaft 1630. The pulley belt arrangement 1670 couples the lower pulley assembly 1640 to the upper pulley assembly 1650. The upper pulley assembly 1650 is mounted near an inside top of the tower 110 via the top shaft 1660. The upper pulley assembly 1650 is coupled to the rail shaft 1690 via cable 1680. The rail shaft 1690 is connected to, is integral with, and/or forms slide bar(s) 210. [ 100] The non-motorized lift-assist mechanism 1610 will now be described in use. The pull- type gas spring 1620 pulls the tension shaft 1630 away from the top shaft 1660, in the direction of the left arrow shown. Through the pulley assemblies 1640, 1650, the pulley belt arrangement 1670, and the cable 1660, the motion of the tension shaft 1630 downwards creates corresponding motion in the rail shaft 1690 upwards (see right arrow) that is three (3) times the motion of the tension shaft 1630. This requires three (3) times the force in the gas spring 1620. In alternative embodiments, other numbers of pulley assemblies are used. Varying the number of pulley assemblies has a corresponding effect on the motion in the rail shaft 1690 relative to the tension shaft 1630 and required force in the gas spring 1620. For example, with more pulley assemblies, the rail shaft could move four (4) times the motion of the tension shaft 1630, requiring four (4) times the force in the gas spring 1620. The upward pulling on the rail shaft 1690 by the cable 1660 via the pulley assemblies 1640, 1650 and the pulley belt arrangement 1670 reduces the upward force and work required by a user when raising the height and increasing the angle of the upper rails 230 relative to the ground. This also makes it easier to lower the height and reduce the angle of the upper rails 230 because it reduces the lifting work required of the user. [101] In an alternative embodiment of the non-motorized lift-assist mechanism 1610, instead of the pull-type gas spring 1620, a push-type gas spring is used (cylinder head of the push-type gas spring is attached to the top of the tower). The push-type gas spring pushes the tension shaft 1630 away from the top shaft 1660, in the direction of the left arrow shown. This causes the rail shaft 1690 to move upwards in the direction of the right arrow. The upward pulling on the rail

shaft 1690 by the cable 1660 via the pulley assemblies 1640, 1650 and the pulley belt arrangement 1670 reduces the upward force and work required by a user when raising the height and increasing the angle of the upper rails 230 relative to the ground. This also makes it easier to lower the height and reduce the angle of the upper rails 230 because it reduces the lifting work required of the user.

[102] FIGS. 21A and 21B illustrate a still further embodiment of an exercise device 1700 with a cycling mechanism 1710. The exercise device 1700 is a simplified version of the exercise devices shown above with respect to FIGS 1-20. Although the elements of the exercise device 1700 are not exactly the same as those described above with respect to FIGS. 1-20, many of the elements are similar. Accordingly, similar elements will be identified with the same reference numbers.

[103] The exercise device 1700 includes the cycling mechanism 1710 attached to the cross member 440. The cycling mechanism 1710 includes a housing 1720, a resistance control mechanism 1730 extending from a flat face 1740 of the housing 1720, pedals 1750 extending from opposite sides of the housing 1720 via cranks for cycling pedaling, a front support assembly 1760, and a rear support assembly 1770.

[104] The front support assembly 1760 includes a forwardly extending curved leg 1780 that is aligned longitudinally with the housing 1720. The leg 1780 terminates in a front cross member 1790. The rear support assembly 1770 includes a rearwardly extending curved leg 1800 that is aligned longitudinally with the housing 1720. The leg 1800 terminates in an upwardly concave cuff 1810 that functions as a quick attachment mechanism.

[105] To quickly attach the cycling mechanism 1710 to the exercise device 1700, the cross member 440 is lifted slightly above the ground, the cuff 1810 is positioned underneath the cross member 440, and the cross member 440 is rested on top of the cuff 1810. With the cuff 1810 under the cross member 440, the weight of the user on the exercise device 1700 maintains the cycling mechanism 1710 securely in position relative to the exercise device 1700. [106] In the embodiment shown, the cycling mechanism 1710 includes an internal magnetic braking mechanism to control resistance during pedaling with the cycling mechanism 1710. With reference to FIG. 21C, an embodiment of the magnetic braking mechanism includes a two- stage transmission. A two stage transmission includes a pedal crank and a large pulley that drives a small pulley on a jack shaft. A second larger pulley on the jack shaft drives a flywheel.

The flywheel spins around the crank shaft, making the cycling mechanism 1710, and especially the housing 1720 of the cycling mechanism 1710, very compact and portable. Pedaling resistance is increased by adjusting the resistance control mechanism 1730 correspondingly, causing moving permanent magnets to move closer to the perimeter of the flywheel. Pedaling resistance is decreased by adjusting the resistance control mechanism 1730 correspondingly, causing a cable connected to an arc shaped linkage that supports the magnets to move the magnets farther away from the flywheel. In alternative embodiments, the resistance control mechanism 1730 includes one or more buttons or other inputs for adjusting pedaling resistance. [107] With reference to FIGS. 2 ID and 2 IE, another embodiment of the magnetic braking mechanism includes a single-stage transmission. The single-stage transmission includes a pedal crank shaft with a large sprocket or pulley that drives a small sprocket or pulley attached to a fly wheel via a chain or belt. This configuration also makes the cycling mechanism 1710, and especially the housing 1720 of the cycling mechanism 1710, very compact and portable. FIGS. 2 ID and 2 IE shows an alternative push-button resistance control mechanism where one or more buttons are pushed for adjusting pedaling resistance.

[108] The compact nature of the cycling mechanism 1710 and the quick attachment mechanism make the cycling mechanism 1710 easy to use, easy to attach/detach, and easy to store/use without taking up much space.

[109] In alternative embodiments, the cycling mechanism 1710 includes alternative braking mechanisms such as, but not by way of limitation, a friction brake mechanism. [110] Although the cycling mechanism 1710 is shown attached to exercise device 1700, in alternative embodiments, the cycling mechanism 1710 is attached to the cross member 440 of the other exercise devices shown and described herein, or other similar exercise devices. [I l l] Installation and use of the exercise device 100, 1110, 1400, 1500, 1600, 1700 (hereinafter "exercise device 100") and some of the components for the exercise device 100 will now be described.

INSTALLING THE FOLDING SQUAT PLATFORM AND TELESCOPING SQUAT STAND

[112] Align bottom of folding squat platform with lower rails just above base . Using the two holes 1/2" from the top of the rails, slide the fixed pin into the hole in the outside left rail . Pull the retractable pin on the right side and move the pin over the hole. Release the pin. Move the folding squat platform until the pin engages completely. Align the telescoping squat stand over

the folding squat platform tubes until the squat stand pins contact the top of the folding squat platform tubes. Pull the retractable pins and adjust the squat stand to the desired height, then release the pins and raise or lower the squat stand until both pins engage in one of the three adjustment holes in the folding squat platform tubes.

ADJUSTING THE PULLEY LOCATOR BRACKETS

[113] Pulley locator brackets are designed to adjust easily. Simply pull back on the adjustable pin, move the pulley locator bracket to the desired position on the lateral adjustable training (LAT) bars, and allow the pin to engage the slotted hole.

USING THE ADJUSTABLE FOOT HOLDER

[114] Prior to use, the adjustable foot holder must be rotated to the upright position. Raise the foot holder until the bracket makes contact with the rail snap button. Depress snap button and hold while raising bracket. Continue raising bracket until snap button engages. To begin using the adjustable foot holder, sit on the glideboard 330. Push in the center post snap button and raise the upper foot pad assembly. Place heels past the pads of the lower foot pad assembly. Lower the upper foot pad assembly once feet are in position. Push in the right rail snap button to lower the adjustable foot holder.

ADJUSTING THE LAT BARS

[115] To adjust the LAT bars, pull the pins on the retractable LAT bar to disengage from the rail and lower or raise LAT bars to the desired position. Ensure that the pins engage. Two LAT bar adjustments can be made to accommodate three positions. Normal use: parallel to the tower PuIl-Up Position: small angle from the rail Fold up Position: parallel to the bottom of the rail

RAISING AND LOWERING THE RAIL ANGLE

[116] To raise or lower the rail angle, stand alongside the upper rail, facing the tower. Hold the tower with one hand while raising or lowering the upper rail with the other hand. Hint: Push backward slightly on the tower when moving the rails up or down, then pull forward when the desired height is reached and allow the tower crossbar to slip into the desired tower level hook. Any time you wish to have the glideboard 330 free from the pulley cable assembly, simply unfasten the snap hook from the "D" ring, releasing the center cable pulley. Store the center cable pulley in the tower handle as shown. Important: Remember to use ergonomically correct lifting procedures. Maintain spine in a neutral position, knees bent. Normal Pull-up Fold-up

TO FOLD THE EXERCISE DEVICE 100 [117] Drop the adjustable foot holder to the down position. To do so, push in the snap button on the inside of the right rail and gently lower the assembly. There is no need to remove the telescoping squat stand and folding squat platform when you move or store the exercise device 100. To fold the folding squat platform, pull the left side retractable pin while pushing the platform gently forward until the retractable pin locks in place in the folded position. Next, adjust the pulley cable pins to the third position on the LAT bars. Ensure that the center pulley is attached to the glideboard 330 "D" ring. Lower the LAT bars to the fold position parallel to the rails. Lower the rails to the bottom position. Push the tower back while you pull the retractable pin on the support strut. When the pin disengages, pull the tower to an upright position. Grab either side of the padded crossbar located in the center of the rails, and pull the rails toward the tower. This will bring the base of the rail to rest on the base of the tower. During this movement, the support strut pin should engage into the folded position. Connect the retainer strap to the glideboard 330 "D" ring to secure exercise device 100 in the upright position. To avoid cable breakage, ensure that cables remain free from contact with hinges, the floor, or wheels. Important: Keep hands, fingers, hair, etc. away from all moving parts. Avoid touching hinges. To move the exercise device 100, stand behind the tower, grasp the tower handle, lean the tower back toward you and roll the exercise device 100 as you would roll a hand truck.

TO UNFOLD THE EXERCISE DEVICE 100 AND RETURN TO USE

[118] Pull the Rail Assembly toward the tower. Remove the retainer strap from the glideboard

330 "D" ring. Disengage the retractable support strut knob. Push the lower rails off and away from the base of the tower. Grasp either side of the padded center rail crossbar and allow the rails to unfold slowly away from the tower until the rails are fully extended. Lift the rails to the desired tower level, ensuring that the support strut knob engages. Adjust LAT bars to desired position. To raise the folding squat platform, disengage the retractable pin on the left side and raise the platform until the pin engages in the upright position.

RESISTANCE CHART FOR EXERCISE DEVICE 100

[119] The resistance required at each level, taking into consideration the weight of the participant, can be found on the Resistance Chart illustrated in FIG. 22. The Resistance Chart is customized to indicate the exercise load required at each level of exercise device 100. NOTE: This required force is simply the exercise load or amount of external work accomplished to move

the glideboard 330 at a specific angle. It does not take into consideration the relative intensity of load when using the pulleys, i.e. knowing how many pounds went up and down the ramp, not how hard it was to pull the weight up and down. The exercise device 100 uses a variable-angle incline plane to create exercise resistance by modifying the user's body weight- the steeper the angle, the more resistance. Simply multiply the user's body weight by the appropriate percentage indicated in the chart. The result of this calculation is the resistance (force) in pounds required to move the glideboard 330. When figuring exercises that incorporate the pulley cables, use 50% of the charted numbers. NOTE: The weight of the glideboard 330 is factored into the resistance chart. Therefore, bodyweight and the level of resistance are the only variables required. [120] It will be apparent to those skilled in the art that various modifications and variations can be made in the exercise devices described above, features of the exercise devices, the methods of using the exercise devices, the methods of instruction using the exercise devices, and other methods described herein without departing from the spirit or scope of the invention. In the claims that follow, elements are generally described in a singular sense; however, the claimed element includes the element in the singular or more than one of the claimed element. Thus, it is intended that the present invention cover modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
