DETAILED DESCRIPTION OF THE INVENTION
[0063] The device and system herein disclosed and described in
[0064] In accordance with one preferred mode of the device 10, per
[0065] The housing 14 is currently formed between 3 and 5 feet in height above the support surface, to ensure a sufficient pathway for proper weight 20 displacement and translation distance for the cable 44, however such may change depending on the weight 20 employed and the exercise machine to which it engages.
[0066] The housing 14 can be constructed of a welded, machined or fastened metal members or tubes to form the rectangular frame 16. Currently the frame 16 has a width of approximately three feet and a height of approximately six feet respectively. It can be formed in a very narrow overall footprint which is only limited by the width of the tubing and as can be seen in
[0067] Securement plates 18 may be provided, which allow the owner to bolt the module to the floor or support surface for added stability. However, all of these dimensions are infinitely variable depending upon the size of the weight and room for placement.
[0068] A weight 20 pivotally engaged with the device 10 is engaged by a member to an upper pivot point or weight bearing 22, which allows the weight 20 to rotate about a linkage shaft 24 engaged to the housing frame 16. The weight 20 in the mode of
[0069] In operation as shown in
[0070] It is this arched pathway for connection of the pin arm 32 to the selection arm 34 such as apertures 35 which is positioned opposite the point of pivoting engagement of the pin arm 32 to the weight 20, or to a member engaged with the weight 20. This arched pathway for engagement such as the apertures 35 and the path followed during rotation of the second end of the pin arm 32, along the same arched pathway defined by apertures 35, allows for significantly increased force adjustment positions as well a much smoother operation and mechanical advantage of the device 10 herein and in all modes herein. The first end of the pin arm 32 will be in a pivoting engagement to frame or to the weight 20 or a member engaged thereto, in a position centered with the arched or curved pathway of engagement to the selection arm 34 such as apertures 35, to allow for the second end of the pin arm 32, to follow the arched pathway and connect to any point there along such as by using apertures 35.
[0071] The pin arm 32 as depicted has a pin arm bearing 30 at a first end in a pivoting engagement to the pin shaft 28. The pin arm 32 is of a length to position an aperture through which a selection pin 36 at the second end is engaged, in operative alignment with each of the apertures 35 along the arched pathway of apertures 35 formed into, or engaged with the selection arm 34.
[0072] Unlike the weight stack resistance provided by conventional machines, where the resistance is varied by engagement or disengagement of individual weights from a stack, the device 10 herein employs the curved or arched pathway of apertures 35 running sequentially along a curved selection arm 34 for this purpose. A pivoting engagement 38 of a first end of the selection arm 34 on a bearing 40, provides a rotational engagement point, of the selection arm at the first end to or with the frame 16.
[0073] The mechanical advantage to elevate the weight 20 and thereby vary resistance communicated to pulling the cable 44, varies along the full length of the selection arm 34 and depending on the engagement point of the second end of the pin arm 32, renders the weight 20, easier or harder to elevate.
[0074] Thus, lower resistance to movement of the weight 20 is communicated to the cable 44 and engaged exercise component 12 with the pin arm 32 engaged as shown in
[0075] The selection arm 34 as can be seen in
[0076] The cable 44, which can alternatively be replaced with a band, strap or cord, or other flexible member, extends vertically from the resistance selection arm 34, through one or a plurality of cable pulleys 46 in the housing frame 14, which transfers resistance from weight 20 elevation, along the cable 44 and to the attached exercise component 12.
[0077] At rest and in the neutral position, the second or distal end of the pin arm 32 rests against a padded ledge 63 on the interior face of the housing frame 14 as shown in
[0078] In all modes of the device 10 shown, connection of the weight 20 to the selection arm 34 runs primarily in a line along the pivotally engaged first end of the pin arm 32 at a central point on the weight 20. The second end of the pin arm 32 as noted is selectively engageable to any aperture 35 along the arched pathway of apertures 35 positioned on or engaged with the selection arm 34. Such is especially desirable in that it provides a straight line force along the axis of the pin arm 32 between from the selection arm 34 and the weight 20 no matter where on arched pathway of apertures 35 engaged to the selection arm 34 the pin arm 32 is engaged.
[0079] In
[0080] As variations in this preferred mode, the lower linkage arm 50 and upper linkage arm 48 can lie on the same or opposing sides of the weight 20 for a lower footprint or increased stability respectively.
[0081] In yet another preferred mode of the device 10 herein, per
[0082] Shown in
[0083] In
[0084] Shown in
[0085]
[0086] Depicted in
[0087] In this mode of the device 10, a sliding engagement of the pin arm 32 at or adjacent the distal end of the pin arm 32 with the selection arm is formed. In a preferred mode, the sliding engagement is formed by a race 54 which defined by the sides of a slot 62 formed in the arched selection arm 34 which is sized for a cooperative rolling engagement with a roller 56 operatively connected to the pin arm 32 (
[0088] Also shown in the
[0089] By forming two curved rows of apertures 35 along the curved or arched pathway, and staggering the apertures 35 in each row, in-between a pair of apertures 35 in the opposing row, very small changes in effective resistance can be accommodated due to the small changes in mechanical advantage. This is highly desirable to users. Further, it is desirable to also progressively shorten the gap between the apertures 35 of each row of apertures 35, to maintain the one to one lift of the weight in relation to translation of the cable 44, and to allow for the even and small changes in the resistance provided by small changes in mechanical advantage. Such small changes is, currently, a change of four to six pounds with five pounds being a favorite. Thus, an engagement of a pin 52 into each successive aperture 35, along the two rows of apertures 35, provides this even change in resistance to movement, and concurrently maintains the one to one ratio of cable translation to lift distance of the weight.
[0090] Still further, it is desirable to limit the distance of rise of the weight, and the distance of travel of the cable. This is further accomplished by forming the lengths of the support arms 68 and 68a substantiality equal and at a length between pivots 69 and 66, which is 80-86 percent of the distance of the pin arm 32 running between the pin 52 and the engagement of the second end of the pin arm to the support arm 68a. Maintaining these ratios will limit the distance of travel of the cable 44 and concurrent equal distance of the rise and lowering of the weight 20, to substantially 18-22 inches. Currently maximizing this weight travel and cable translation to 20 inches is a particular favored configuration since is works well to allow use of the device 10 in very confined spaces.
[0091] Additionally, as noted and as can be seen in
[0092] This sequentially smaller spacing between the adjacent apertures 35 in the arched row or rows of apertures 35, formed into the selection arm 34, as the apertures become closer to the first end 58 is preferred as noted. This is because the engagement between the pin 52 and one of apertures 35 in either row, at any position along the arched row of apertures 35, forms a connection to with the weight 20, such that a 1 to 1 ratio of rise of the weight 20, to the distance of travel of the cable 44 is maintained, and the changes in force required to raise the weight change in even increments.
[0093] Thus, a user pulling a handle engaged to the cable 44 a distance of one foot, will concurrently raise the weight 20, one foot in elevation. This substantially equal rise to travel distance also helps maintain the force required to move the weight 20 at any given pin 52 and aperture 35 engagement along the sequence, equal or the same throughout a given repetition of the user which moves the cable 44, and in equal changed increments from adjacent apertures 35, no matter which individual aperture 35 is engaged by a pin 52.
