This invention relates generally to a multi-functional weight training or functional trainer exercise machine or apparatus which enables performance of multiple exercises in various positions.
Some known functional trainer exercise machines include an upright frame holding one weight stack or dual weight stacks, with left and right arms extending from the frame and each having an outer end comprising a vertical track carrying a vertically adjustable pulley carriage and having indexing holes for adjusting the carriage height. Left and right handles are secured to the ends of cables extending around the pulleys in the respective pulley carriages and secured to the weight stack or stacks via a cable and pulley linkage. In these prior machines, the pulley carriage and pulleys travel along the vertical track and are secured at a selected height by indexing pins which extend through selected indexing holes for adjusting the pulley height and thus the handle position for different exercises. The carriage, pulleys, and indexing pin are all external and project outward from the track, and adjustment can be awkward for the user. The exposed pulleys are susceptible to damage when the handle is released.
In one aspect, a functional trainer or other exercise machine has a frame with at least one column rotationally mounted between upper and lower frame portions, the column being hollow along at least a major portion of its length to define an internal channel with an internal track extending along the channel, and having an opening extending along at least a major portion of the length of the channel, and a pulley carriage assembly configured for traveling along the internal track with the majority of the pulley carriage assembly located inside the column. A cable assembly comprising one or more cables is suitably linked to an exercise resistance and extends around one or more pulleys of the pulley carriage assembly and out of the assembly, with the end of the cable terminated to a cable pull which may be secured to a selected accessory such as a pull handle 45 or the like.
In one embodiment, the pulley carriage assembly comprises a carriage, one or more pulleys rotationally mounted between pulley mounting portions of the carriage, a spring loaded indexing pull pin, and one or more wheels, rollers, or other travel members configured to travel along one or more internal tracks in the column. In one embodiment, a vertical indexing plate with spaced holes is also located inside the column, and an indexing pull pin extends through a selected hole in the indexing plate to secure the carriage assembly at a desired height. In one embodiment, the assembly also includes a pulley cover pivotally mounted over the front of the pulley carriage to extend over the pulleys and act as a guard to guard the pulleys from damage when the pull end of the cable is released. The pulley cover has an opening through which the cable extends. In one aspect, the indexing pull pin is associated with the pulley cover, which has a grip area for gripping by a user and pivoting the cover slightly outward to disengage the pull pin from an aligned indexing hole so that the height of the pull end of the cable can be adjusted. In order to adjust the height of the pulley carriage, the user simply grasps the pulley cover (at the cushioned grip area) and pulls outward to disengage the spring driven indexing pull pin. Once the desired height position is reached, the pulley cover is released so that the spring driven indexing pull pin extends into an aligned hole in the indexing plate.
In one embodiment, respective first and second columns are rotationally mounted between upper and base frame members of respective side frames of the machine, with each column having at least one internal guide track in which respective pulley carriage assemblies are engaged for movement up and down the frame.
The rotating column may be either an extrusion or a welded assembly. In one embodiment, the pulley carriage uses shouldered axles for mounting the pulleys as well as the wheels (or rollers) engaging the guide track. In this way, when all the components are assembled and inserted into the rotating column, there is no need for any retaining hardware such as nuts or snap rings.
The internal mounting of both the pulley carriage and the indexing plate results in clean aesthetics and ease of adjustment. The cable, indexing holes, indexing pin and wheels (or rollers) are all hidden within the rotating column. The pulley cover is the only visible item protruding from the rotating column, and is dual purpose since it both guards the pulleys against damage when the pull end of the cable is released, and also provides the means for operating the spring loaded indexing pull pin, avoiding the need for another manual engagement device such as a knob or lever.
Other features and advantages of the present invention will become more readily apparent to those of ordinary skill in the art after reviewing the following detailed description and accompanying drawings.
The details of the present invention, both as to its structure and operation, may be gleaned in part by study of the accompanying drawings, in which like reference numerals refer to like parts, and in which:
Certain embodiments as disclosed herein provide for a functional trainer exercise machine having a frame and at least one column rotationally mounted between upper and lower or base frame members with a pulley carriage traveling on tracks inside the column and an indexing plate with holes also located inside each column to allow height adjustment of the respective pulley carriage via a spring loaded pull pin or other releasable locking device. In one embodiment, the frame has opposite side frames and respective first and second columns are rotationally mounted between upper and lower frame members of the respective side frames.
After reading this description it will become apparent to one skilled in the art how to implement the invention in various alternative embodiments and alternative applications. However, although various embodiments of the present invention will be described herein, it is understood that these embodiments are presented by way of example only, and not limitation.
On each side of the machine, a cable assembly which may comprise one or more cables 30 extends between a respective weight stack 15 and the respective pulley carriage assembly 22 around various pulleys in the frame, as best illustrated in
Base or lower frame member 48 and top or upper frame member 50 extend from lower and upper portions of weight stack housing 14, respectively. The base frame member 48 and upper frame member 50 may optionally be parallel to each other. Base frame member 48 also includes front and rear support feet 52, 54. A chin-up bar 55 extends between the forward ends of upper frame members 50.
One of the pulley carriage assemblies 22 will now be described in more detail with reference to
As illustrated in
The top and bottom column mounts 80 and 82 are each rotationally secured to the respective spindles 90, 92, as seen in the exploded view of
In the above embodiment, spindles 90, 92 are part of the top and base frames 50, 48 and the column mounts 80, 82 are rotationally secured to the spindles 90, 92 prior to attachment to the top and bottom ends of the columns 20 on each side of the machine 10.
In one embodiment, in order to mount columns 20 to the respective side frames 18 using the modified top and bottom end mounts 110, 131, each cable or cable assembly 30 is first routed through the framework and components between the respective weight stack 15 and pulley carriage assembly 22. One cable end is extended upward from lower pulley 33 through the bottom assembled column end mount 131 and secured via cable tie 64 to cable anchor 63 of the pulley carriage 58. The other cable end is extended downward from upper pulley 37 through the top cable mount 110, and through carriage assembly 22 between pulleys 36 and out of cover opening 38, before connecting to cable pull 42 (see
In the foregoing embodiments, the cable 30, indexing plate 25 with holes 26, indexing pin 28, and wheels or rollers 62 of the pulley carriage 58, as well as most of the pulley carriage assembly 22 itself, are all hidden within the rotating column 20. The only visible item protruding from the column 20 is part of the pulley cover 60, which has the dual function of guarding the pulleys 36 from damage when the pull end 42 of the cable 30 is released by a user, and also acting as a grip 74 for a user to release the pull pin 28 from an indexing hole 26 and allowing the carriage assembly 22 to be raised or lowered to a desired height, at which point the cover 60 is released to allow the pin 28 to engage in an aligned, completely hidden hole 26 in the indexing plate 25. This arrangement provides clean aesthetics as well as ease of cable pull 42 height adjustment.
Although the exercise resistance in the above embodiments comprises dual weight stacks 15 each linked to a respective pulley carriage assembly 22, the resistance may alternatively be a single weight stack 15 to which each pulley carriage 58 is linked in alternative embodiments. Any other type of resistance known in the art may alternatively be used, such as weight plates, hydraulic, pneumatic, electromagnetic, or elastic bands, in place of the weight stack 15. Although there are two rotating columns 20 each containing a movable pulley carriage assembly 22 with respective cable pulls 42 extending out of the column 20 in the above embodiments, the apparatus 10 may have a single rotating column 20 or three or more such columns 20 in alternative embodiments. Additionally, although the carriage 58 is described as having wheels or rollers 62 which engage in the opposing tracks or grooves 76, any other type of device configured for travel along the tracks or grooves 76 may be used in place of wheels or rollers 62, such as sliders, roller bearings, or the like. The two opposing grooves 76 in which wheels or rollers 62 are engaged in the foregoing embodiments may be replaced by a single groove or track 76 engaged by a single roller 62, roller bearing or slider on the carriage 58 in alternative embodiments.
