DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
FIGS. 1A-6 illustrate a number of embodiments of collapsible inclinable exercise devices 100A, 100B, 100C, 100D including a collapsing mechanism 110. Before describing the collapsing mechanism 110 in detail, the collapsible inclinable exercise devices 100A, 100B, 100C, 100D will first be generally described.
The inclinable exercise devices 100A, 100B, 100C, 100D include tower 120 with a carriage 130 vertically slidable along the tower 120.
As shown in FIGS. 2-6, bottom rails 140 are pivotally coupled to top rails 150 at pivot(s)/hinge(s) A. Top rails 150 are pivotally connected to carriage 130 at pivot(s)/hinge(s) B. A plyo strut 160 is pivotally connected at one end to a base 170 at pivot(s)/hinge(s) C and is pivotally connected at an opposite end to bottom rail 140 at pivot(s)/hinge(s) D.
A lift-assist mechanism 180 is pivotally connected at one end to the plyo strut 160 at pivot(s)/hinge(s) 190 and is pivotally connected at an opposite end to the top rails 150 at pivot(s)/hinge(s) 200. In the embodiment shown, the lift-assist mechanism 180 includes two push-type gas spring/struts between the plyo strut 160 and the upper rail 150. The gas struts attach at angles to prevent pinch point(s) and to balance the load symmetrically. The combined force of the gas struts performs two separate functions: 1) level change lift assist, and/or 2) fold lift assist. The push-type gas spring provides an upward angled force towards the pivot(s)/hinge(s) 200, reducing the upward force and work required by a user when raising the height and increasing the angle of the top rails 150 relative to the ground and when folding/collapsing (See FIG. 3) the inclinable exercise device 100A, 100B, 100C, 100D. This upward force imparted by the lift-assist mechanism 180 also makes it easier to lower the height and reduce the angle of the top rails 150 because it reduces the lifting work required of the user.
As shown in FIGS. 1A-1G, a user support platform or glideboard 210 with rollers (not shown) rolls along the rails 140, 150.
The carriage 130 is coupled to arms 220A, pulley arms 220B. Attached to the arms 220A, pulley arms 220B are pulleys 230.
Although not shown, a connector extends through the pulleys 230 and connects to the user support platform 210. The connector may be of any suitable well-known type, but is preferably a cable with handles at each end. The cable extends through the pulleys 230 positioned on the pulley arms 220A, 220B and loops through a third pulley attached to the user support platform 210. The third pulley is positioned along the lateral centerline of the user support platform. This position allows for unilateral (i.e. one arm), bilateral (i.e., two arm) and static equilibrium (i.e. holding the user support platform 210 suspended by keeping a constant force on each handle) use. The cable should preferably be of sufficient length to extend through the pulleys 230 and allow the exerciser to grasp one or both of the handles while the exerciser is on the user support platform 210 and the user support platform 210 is at rest.
In an alternate embodiment, the connector is two separate cables extending through the pulleys 230 with each cable fixedly attached to the user support platform 210.
As shown in FIGS. 1B-1G, the collapsible inclinable exercise devices 100A, 100B, 100C, 100D include tower cap 232, fold bar 234, pulley attach bars 550, incline scale 236, cable handles 238, tower foot 240, foot holder 242, gas struts 244, squat stand 246, squat handle 248, squat adjust lever 250, squat forks 252, rail base 254, rail foot 256, removal pull pin 258, squat fold pull pin 260, index pin plate 262, glideboard “D” ring 264, rail fold latch/arm/lever 400, rail lock 350, transport wheels 268, tower lift-lock lever, center pulley storage ring 272, rail incline release lever 274, foot holder removal pull pin 276, foot holder lowering lever 278, incline up/down switch 280, LED 282, remote control cable handlebars 284, glideboard frame 286, tilt adjust lever 288, and safety key 290.
With reference to FIGS. 2-6, the collapsing mechanism 110 will be described in more detail. The collapsing mechanism 110 includes the pivot(s)/hinge(s) A, B, C, D located at strategic locations on the inclinable exercise device 100A, 100B, 100C, 100D so as to facilitate collapsing and deployment of the inclinable exercise device 100A, 100B, 100C, 100D while preventing the tower 120 from accidentally toppling over during collapsing, deployment, and/or use. In FIGS. 2-6, lines identified as Link 1 L1 (or top rail 150/Link 1 L1), Link 2 L2 (or bottom rail 140/Link 2 L2), Link 3 L3 (or plyo strut 160/Link 3 L3), and Link 4 L4 (or tower 120/Link 4 L4) are shown between pivot(s)/hinge(s) A, B, C, D. These lines are shown to assist the reader in understanding the invention and do not represent any structural elements. The inclinable exercise device 100A, 100B, 100C, 100D is indicated herein as having a four-bar linkage between top rail 150/Link 1 L1, bottom rail 140/Link 2 L2, plyo strut 160/Link 3 L3, and tower 120/Link 4 L4. It should be noted that the lift-assist mechanism 180 is not shown in FIGS. 4-6 in order to assist the reader in understanding the invention.
Pivot(s)/hinge(s) A allows the top rails 150 and the bottom rails 140 to pivot relative to each other, which is important when collapsing/folding the rails 140, 150 together for storage of the inclinable exercise device 100A, 100B, 100C, 100D.
Pivot(s)/hinge(s) B allows the top rails 150 to pivot relative to the carriage 130, which is important when adjusting the height of the carriage 130/incline of the rails 140, 150.
Pivot(s)/hinge(s) C is positioned relative to the base and relative to carriage 130 and rails 140, 150 so that the tower 120 is always structurally supported (e.g., to prevent the tower 120 from accidentally falling over during collapsing and deployment of the inclinable exercise device 100A, 100B, 100C, 100D). For example, as shown in FIG. 4, even when the carriage 130 is at its lowest position relative to the tower 120, pivot(s)/hinge(s) B are above pivot(s)/hinge(s) C, which are at the base 170. Because the lateral movement of the tower 120 is restricted at two vertically spaced points, one at the base 170, one vertically spaced above the base 170, the tower 120 may lean slightly away from vertical, but is prevented from toppling over.
Pivot(s)/hinge(s) D is positioned relative to the pivot(s)/hinge(s) A so that the lift-assist mechanism 180 can provide folding assistance when folding/collapsing the rails 140, 150 and the inclinable exercise device 100A, 1008, 100C, 100D. The top rail 150 and the bottom rail 140 are pivotally coupled to each other at and define a first rotational axis at Pivot(s)/hinge(s) A. A second end of the plyo strut 160 is pivotally coupled to the bottom rail 140 of the adjustable incline at and defining a second rotational axis at Pivot(s)/hinge(s) D, which is a second location that is not the same as the first location so that the first and second rotational axes are not collinear.
With reference to FIGS. 2 and 3, lift assistance and fold assistance provided by the lift-assist mechanism 180 will be described in more detail.
With reference to FIG. 2, the lift-assist mechanism 180 (e.g., gas strut) is attached between the plyo strut 160 and the top rail 150. When raising the carriage 130 and the angle of the rails 140, 150 to adjust the incline of the rails 140, 150, the carriage 130 slides along the tower 120. The top rails 150 and the bottom rails 140 act together as a single link. The tower 120 anchors the lower pivot point C of the plyo strut 160. The force of the strut 180 acts strongly to rotate Link 2 L2/bottom rail and Link 1 L1/top rail about pivot(s)/hinge(s) D to provide lift assistance, reducing the upward force and work required by a user when raising the height and increasing the angle of the top rails 150 relative to the ground.
With reference to FIG. 3, the lift-assist mechanism 180 (e.g., gas strut) is attached between the plyo strut 160 and the top rail 150. When folding the inclinable exercise device 100A, 100B, 100C, 100D, with the carriage 130 lowered to its lowest vertical position shown in FIG. 3, the tower 120 and the carriage 130 remain relatively stationary, anchoring the lower end of the plyo strut 160. The force of the lift-assist mechanism 180 acts roughly along the top rail 150/Link 1 L1. This causes the lower rail 140/Link 2 L2 to rotate around pivot(s)/hinge(s) D, the top pivot of the plyo strut 160/Link 3 L3. This mode of force is referred to herein as fold, folding, or collapsing assistance.
With reference to FIGS. 4-6, the stability features of the collapsing mechanism 110 to prevent the tower 120 from accidentally toppling over during collapsing, deployment, and/or use will now be described in more detail.
With reference to FIG. 4, when the rails 140, 150 are at the lowest angle possible, the top rail 150/Link 1 L1 and the bottom rail 140/Link 2 L2 are in toggle (i.e., they are in line and can exert maximum force from one to another). The tower 120 is a sliding link (Link 4 L4), which is mostly vertical. Since there is vertical separation between pivot(s)/hinge(s) B and C, even when the rails 140, 150 are at the lowest angle possible, the tower 120 is supported so it will not fall down.
With reference to FIG. 5, the inclinable exercise device 100A, 100B, 100C, 100D can only fold by lifting the rails 140, 150. It is important to note the angle change in bottom rails 140/Link 2 L2 during folding (i.e., progressing from configuration shown in FIG. 4 to configuration shown in FIG. 6). The bottom rail 140/Link 2 L2 is nearly horizontal when folding was started and tower 120/Link 4 L4 was nearly vertical (See FIG. 4). Because top rail 150/Link 1 L1 and plyo strut 160/Link 3 L3 are long relative to bottom rail 140/Link 2 and tower 120/Link 4 L4, they remain relatively parallel to each other through out 90 degree rotation during folding. The bottom rail 140/Link 2 L2 undergoes a rotational angle change of 90 degrees relative to stationary tower 120/Link 4 L4. In all stages of folding the inclinable exercise device 100A, 100B, 100C, 100D, the tower 120 is supported and stable so it will not fall.
With reference to FIG. 6, continued lifting of the rails 140, 150 in the manner shown causes the inclinable exercise device 100A, 100B, 100C, 100D to fold. It is important to note the angle change of bottom rail 140/Link 2 L2, which goes into toggle in the opposite direction to that mentioned above when folded all the way at the top. In all stages of folding the inclinable exercise device 100A, 100B, 100C, 100D, the tower 120 is supported and stable so it will not fall.
Thus, the four-bar linkage between top rail 150/Link 1 L1, bottom rail 140/Link 2 L2, plyo strut 160/Link 3, and tower 120/Link 4 L4 of the inclinable exercise device 100A, 100B, 100C, 100D simplifies folding and unfolding to constrain and control all parts throughout the kinematic motion of folding and unfolding. This eliminates the need of restraining pins during the process. Reducing the number of steps to fold and unfold reduces the probability of a user to make a mistake and become injured or cause property damage. The four-bar linkage maintains stable support for the tower 120 throughout all levels of incline and all angles during folding. The linkage lengths are optimized so that the tower 120 leans the minimum forward when inclined and the minimum backward when folding and the plyo strut 160 does not need to be telescoped. The four bar linkage also allows the range of inclines to be lowered safely without adding locking pins to prevent the tower 120 from accidentally falling.
Additional Features
With reference to FIGS. 7A-17C, one or more implementations of the inclinable exercise device 100A, 100B, 100C, 100D include one or more of the following:

    
    
        1) As shown in FIGS. 7A-11C, the inclinable exercise device 100A, 100B, 100C, 100D includes a lat bar cam mechanism 300 attached to the carriage 130 that causes pull pins 305 to automatically engage slots 308 when the lat bar 220B is raised manually or automatically when the inclinable exercise device 100A, 100B, 100C, 100D is folded. The pull knobs 310 at the end of the pull pins 305 are pulled outwardly to disengage the pull pins 305 from the slots 308 to unlock the lat bar 220B. The lat bar 220Bs are lowered to the position shown in FIG. 9 for doing pull ups. FIGS. 7A, 7B show that the pull pin 305 restrains LAT bar rotation forward by slot 308 with LAT bar 220B in the upright position. FIGS. 7C, 7D show that flange 330 on carriage 130 acts as a cam to push LAT bar pull pin 305 in as LAT bar 220B rotates from pull-up position to upright/fold position. During this transition rotation, the flange/cam 330 just begins to press in the pull pin 305. FIGS. 7E, 7F show LAT bar pull pin cylinder restrains rotation to contact the rail 150 with the LAT bar 220B in the pull-up position;
        2) With reference to FIG. 12, there is an automatic rail lock mechanism 350 that will engage at high inclines (e.g., for plyometrics) and will disengage at low inclines for folding the inclinable exercise device 100A, 1008, 100C, 100D. The rail lock mechanism 350 includes a top rail flange/hinge 360, a bottom rail flange/hinge 370, a rail lock cam mechanism 380, a cam member 390, an arm/lever 400, a spring 410, a pivot 420, a slot 430, and an engagement arm/rod 440. The spring 410 urges the arm/lever 400 to engage the slot 430 to lock the rails 140, 150 together via the top rail flange/hinge 360 and the bottom rail flange/hinge 370. This prevents the rails 140, 150 from folding during plyometric use. The rail lock mechanism 350 automatically releases when the rails 140, 150 are at the lowest level where the inclinable exercise device 100A, 1008, 100C, 100D can be folded. At this lowest level, the engagement rod 440 on the plyo strut 160 contacts the cam member 390, causing the arm/lever to rotate out of the slot 430, allowing the rails 140, 150 to pivot/fold relative to each other. When the rails 140, 150 are linearly aligned and simultaneously raised from the lowest level, the engagement rod 440 moves away from the cam member 390, allowing the spring 410 to urge the arm/lever 400 to engage the slot 430 to lock the rails 140, 150 together via the top rail flange/hinge 360 and the bottom rail flange/hinge 370;
        3) With reference to FIGS. 12 and 13, rollers 450 of the support platform/glideboard 210 roll on inside/inside track 460 of the rails 140, 150 to allow tilting support and steeper incline support all the way to vertical. The rollers 450 inside the rails 140, 150 also add more stability, which is necessary for the tilting user support platform/glideboard 210. Each inside track 460 includes lower/upper engagement faces 470, inner wall 480, and lower/upper faces 490. The rollers include two materials: a soft rolling member/tire 500 for quiet smooth rolling on aluminum lower/upper engagement faces 470, and a flange 510 made of a hard slippery nylon to keep the user support platform/glideboard 210 on track without creating excess drag when twisting loads are applied;
        4) With reference to FIG. 14, the tower 120 includes a ladder of rungs/bars 550 in a center channel 560 on a front 570 of the tower 120 to hook (via a connector/clip 580) a center pulley 590 or a leg pulley (for a leg pulley accessory) at various positions. Attaching the pulley 590 reduces the mechanical advantage and reduces cable length, providing more resistance loading for more exercises. The center pulley 590 is connected to a rung 550 at a height/level at or below the height/level of the pulleys 230 The leg pulley accessory also benefits from having a variety of attach points to improve the line of resistance;
        5) With reference to FIGS. 15A-15C, a handle 600 at a top of the tower 120 functions like a car door handle at the top of inclinable exercise device 100A, 1008, 100C, 100D. The user first lifts the rails 140, 150 slightly to unload the handle 600, then pulls the handle 600 forward toward the rails 140, 150, and then lowers the rails 140, 150 to the desired incline. The handle 600 is operably coupled to latch 611 in the tower 120 to lock/unlock the position of the carriage 130. The handle 600 includes a plate 612 with a hole 613 that receives an actuation lever pin 614. A cam tube 615 rotates about off-axis pivot bolt 616, causing actuation lever pin 614 to move within directing slot 617 of top tower plate 618. The off-axis rotation of cam tube 615 causes lever 619, which receives tube 615, to move towards (or away from) the rails 140, 150. Pulling of the handle 600/rotation of the tube 616 towards the rails 140, 150 causes latch 611, which is welded to lever 619 to move outward, and disengage slot 622 (to unlock the position of the carriage 130) and releasing of the handle 600/spring-biased rotation of the tube 616 away from the rails 140, 150 causes latch 611 to move inward, and engage slot 622 (to lock the position of the carriage 130). Springs respectively bias the handle 600, tube 616, and latch into a home position and inhibit play/rattling in the handle 600, tube 616, and latch 62. The user can always raise the rails 140, 150 by lifting them from any convenient hand hold position, including lifting via the arms 220A, 220B and/or via the carriage 130;
        6) With reference to FIGS. 16A and16B, an embodiment of a carriage lock mechanism 650A includes a carriage lock pin 651 that engages a hole on a rear face of slidable carriage cuff 670 for locking the carriage 130 to the tower 120. FIG. 16B illustrates the lock pin 651 stored in a hole on a top face of the carriage 130. The carriage lock pin 651 allows a user to lift the tower 120 from the back 670 for moving the inclinable exercise device 100A, 100B, 100C, 100D in a room; and/or
        7) The user support platform/glideboard 210 is a tilting glideboard 210.
    
    


With reference to FIGS. 17A-17C, a pulley locator clamp 700 clamps the pulley 230 to rubber-coated bar/arm 220A, 220B. The pulley locator clamp 700 includes a series of curved arms/members 710 that are connected to each other at pivots/fasteners 720. Main curved member 710 includes a receiving hole 725. Torsion springs 730 urge the pulley locator clamp 700 to the position/configuration shown in FIG. 17A. A connector 740 attaches the pulley locator clamp 700 to the pulley 230. As shown in FIG. 17C, when inner and outer points of the pulley locator clamp 700 are squeezed together, circular hole 750 is formed with a diameter greater than the diameter of the bar/arm 220A, 220B, allowing the pulley locator clamp 700 (and pulley 230) to be moved over the bar/arm 220A, 220B to a desired location over bump 755 extending from the bar/arm 220A, 220B. Once in the desired location, the inward pressure on the pulley locator clamp 700 is released and the springs 730 urge the clamp 700 onto the bar/arm 220A, 220B so that the receiving hole 725 of the main curved member 710 receives the bump 755.
