TITLEAdjustable seat for strength training deviceINVENTORJason Lazar of Denver, ColoradoCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of priority pursuant to 35 U.S.C. § 119(e) of U.S. provisional application no. 63 / 594,949 filed 31 October 2023 entitled “Adjustable seat for strength training device,” which is hereby incorporated herein by reference in its entirety.TECHNICAL FIELD

[0002] The technology described herein relates to accessory products for strength training devices with cable pull weight stacks and cage or frame structures.BACKGROUND

[0003] Functional trainers are mechanical strength training devices that typically incorporate cable routing systems, usually incorporating pulleys, to connect one portion of a cable system to a resistance source and a second portion of the cable system to a user attachment. A user interacts with the attachment, e.g., a handle or pull bar, to pull on a cable and thereby engage the resistance source to perform a strength exercise. The resistance source is typically a weight stack but may also be a configuration of elastic resistance bands. In some configurations, the functional trainer can be incorporated into a frame, cage, or similar structure for performing free weight exercises. A lat pull-down exercise is typically performed in a seated position pulling on a pull bar positioned above the user.

[0004] The information included in this Background section of the specification, including any references cited herein and any description or discussion thereof, is included for technical reference purposes only and is not to be regarded subject matter by which the scope of the invention as defined in the claims is to be bound.SUMMARY

[0005] The technology disclosed herein relates to an adjustable seat accessory for a strength training device including a cable-pulley system and a weight stack assembly. In one example implementation, an adjustable seat for a strength training device includes a seat and a mounting mechanism for attachment of the adjustable seat to the strength training device. The seat defines a top surface and a bottom surface. A seat adjustmentplate is mounted to the bottom surface of the seat. A height adjustment plate is connected to the mounting mechanism. An articulating arm is disposed between and connected at a first end to the seat adjustment plate at a first pivot point and connected at a second end to the mounting mechanism at a second pivot point. A first adjustment mechanism is interposed between the seat adjustment plate and the articulating arm and is adjustable to pivot the seat about the first pivot point with respect to the articulating arm. A second adjustment mechanism is interposed between the height adjustment plate and the articulating arm and is adjustable to pivot the seat about the second pivot point with respect to the mounting mechanism.

[0006] In another example implementation, an adjustable seat for a strength training device includes a seat and a mounting mechanism for attachment of the adjustable seat to the strength training device. An articulating arm is pivotably connected at a first end to the seat at a first pivot point and pivotably connected at a second end to the mounting mechanism at a second pivot point. The seat is adjustable in first discrete angular increments with respect to the first pivot point. The articulating arm is adjustable in second discrete angular increments with respect to the mounting mechanism.

[0021] This disclosure relates to implementations of a multi-functional and adjustable seat for attachment to various strength training devices that include a rack or frame with vertical post members. Example strength training devices that can accommodate the adjustable seat include functional training devices and weight cages. The adjustable seat is configurable to provide an integrated combination of functional accessories to a strength training device: a lat pulldown seat and chest-supported row pad. A lat pull-down exercise is used to target the latissimus dorsi muscles (i.e. , in the back). It is typically performed seated, facing towards the strength training device. The seated user grasps and pulls a longbar attached to a resistance force (e.g., weight plates) via a cable toward the chest and then slowly extends the arms back to starting position. The chest-supported row is a back exercise that involves resting the chest on an inclined surface with feet on the floor, grasping and pulling weights (e.g., dumbbells) upward toward the torso, and then extending the arms downward to the starting position.

[0022] The adjustable seat achieves this functional diversity through the incorporation of adjustment mechanisms that pivot on two independent, parallel axes. This allows both the height and angle of the seat to be adjusted to provide the multi-functionality discussed above. In some example implementations, ball bearings can be used at the points of rotation to achieve smooth rotation with a tight feel. A first or front adjustment mechanism operates as a fine “height adjuster” for the seat. In an example implementation, the height adjuster has four points of adjustment (e.g., at 0, 12.5, 25, 40 degrees with respect to a position of the lowest adjustment point). A spring pop-pin can be used to lock the front adjustment mechanism at each of these angular positions.

[0023] A second or rear adjustment mechanism is located on the seat and operates as a “seat angle adjuster.” This rear adjustment mechanism allows the user to change the angle of the seat pad independent from the front adjustment mechanism. In one example implementation, the seat adjuster has seven points of adjustment. The angles of the adjustment points on the front adjustment mechanism and the rear adjustment mechanism are configured to correspond to each other so that the seat can remain "flat" if the user desires through the range of motion. Stated alternatively, the angle of adjustment of the height adjuster always has a matching angle among the adjustment points of the seat angle adjuster so that the seat can always be positioned parallel to the floor.

[0024] Typically users place a weightlifting bench next to a weight rack with an attached leg roller as a way to perform seated lat-pull-downs using a functional trainer cable system. The user places the knees under the leg roller to assist in remaining seated during the exercise. This is a cumbersome set-up that is far from perfect and this may deter people from using cable attachments designed for lat pull-down exercises on functional trainer devices. The disclosed adjustable seat attachment offers a solution that is easy to set up and provides lots of adjustability. Similar to a commercial-style lat-pull-down machine, the seat is pad wide and the attachment has integrated leg rollers to hold down the user’s legs. Furthermore, the height of the leg rollers can be adjusted to achieve the desired comfort of the user. In example implementations, the height of the leg rollers can be adjusted by telescoping a liner post upward and downward, in and out of a larger housing channel. Multiple set points of adjustment can provided for the height of the leg rollers. A pop-pin can be used to lock the leg holders in place. A handle atop the telescoping post allows for easy adjustment.

[0025] In another example implementation, the leg rollers are removable from the telescoping post of the adjustable seat. In one example, the rollers can be mounted on opposing shafts having a male threaded stud and a female tapped cavity, respectively, such that the opposing shafts can be screwed together for attachment to any corresponding receiving structure and unscrewed for removal from the structure. The user can thus remove the leg rollers from the main body and attach them directly to rack structures (posts or beams) or other attachments (e.g., ISO arms) to perform exercises such as Bulgarian split squats, sit-ups, or sissy squats. The leg rollers fit into opposing holes in frame members and threaded together.

[0026] Example implementations of the adjustable seat are designed to be attached to and used on various cable machines with vertical rack or frame posts. The adjustable seat is removable from the rack post when not in use. Implementations of the post attachment mechanism of the adjustable seat feature a function that allows for tightening of the interface between the post attachment mechanism and the vertical post to remove any wobble in the adjustable seat while performing an exercise. For ease of attachment to a vertical rack or frame post, a certain amount of “slop” or “gap” is required in the attachment channel (e.g., C- cup) to ensure that the attachment can always fit despite tolerances in the upright post. For attachments such as J-cups and safeties, some “slop” is acceptable. However, for a device like the adjustable seat attachment, any amount of “slop” will make the device feel unstable or cheap. For this reason, a set of liners is provided within the attachment channel with an accompanying adjustment mechanism that allows one or more of the liners to be pushed into the post to remove any excessive gap, eliminate wobble, and provide a “solid feel” to the user. In one example implementation, a thumb screw pushes a steel plate and polyurethane liner into the post to close the gap.

[0027] The adjustable seat can thus move up and down an upright post of a strength training device to achieve desired height for seated lat pull-down exercises. The height of leg rollers corresponding leg rollers can also be adjusted for user comfort. Because the angle of the seat adjusts independently from the height adjuster, the adjustable seat can also be used to perform a variety of chest supported exercises such as rows of flies. The angle of the seat can be adjusted by both pivot points to achieve the desired height, position, and comfort for the exercise movement.

[0028] The figures accompanying this written description, and as briefly described above, together depict an example implementation of an adjustable seat device 100 as initially presented in FIG. 1. Primary components of the adjustable seat device 100 can include a seat 102, leg rollers 104a / b, a mounting mechanism 105, an articulating arm 106, a seat handle 108, and a post handle 110, which are described in greater detail below.

[0029] The seat 102 is used as a basis for orientation within the figures. The seat 102 has a top side or surface 112, a bottom side or surface 114, a front end 116, and a rear end 118. Although depicted for simplicity in cross-section in FIG. 5 as a single, uniform material, the seat 102 can be constructed as is typical for padded seats in exercise equipment. Such construction ordinarily includes a seat cushion (e.g., a thickness of foam padding) placed upon and fixed (e.g., with an adhesive) to a rigid, planar substrate (e.g., a piece of plywood) and covered by upholstery (e.g., a vinyl fabric). The form factor of the seat 102 may be designed in a variety of shapes. In the present example, the lateral sides toward the front end 116 of the seat 102 taper inward to provide additional clearance for a user’s legs when performing seated exercises.

[0030] A seat pull 120 may be attached to the bottom surface 114 at the rear end 118 of the seat. The seat pull 120 can be designed with any form factor to protrude from the bottom surface 114 at the rear end 118 of the seat that allows the fingers of a user to find purchase to more easily manipulate an angle of the seat 102 or aid in lifting the seat 102 as further described herein. In the example shown in the figures, particularly in FIGS. 2 and 3, the seat pull 120 is generally a half cylinder form (e.g., of molded plastic) that is fastened (e.g., with screws) to the bottom surface of the seat 102.

[0031] A planar seat mounting plate 122 can be placed underneath the seat 102, i.e. , against the rigid substrate supporting the seat cushion and fastened thereto, e.g., with screws extending through apertures in the seat mounting plate 122 and into the rigid substrate. The seat mounting plate 122 may be made of heavy gauge steel and extend across a majority of the surface area of the bottom surface 114 of the seat 102 to provide adequate structure to support the weight of a user. The seat mounting plate 122 may further defined cutouts as shown in FIG. 2, which can reduce the weight of the adjustable seat device 100 when removed or adjusted by a user, without significantly impacting the structural integrity or load-bearing capability thereof.

[0032] An seat adjustment plate 124 extends normally downward from the longitudinal center of the seat mounting plate 122. The front edge of the seat adjustment plate 124 defines an arc of a first radius from the bottom surface 114 of the seat 102 to a point slightly to the rear of a vertical position of a first pivot point (indicated by rear pivot shafts 146a / b). The seat adjustment plate 124 can be made of steel and can be fixed, e.g., by a weld, to the seat mounting plate 122. Additional structural support members, e.g., rear counterforts 126a / b and front counterforts 128a / b may extend normally from both the bottom surface of the seat mounting plate 122 and the seat adjustment plate 124 and fixed to each, e.g., with welds. A plurality of adjustment apertures 130 can be formed within the seat adjustment plate 124 along an arcuate path adjacent to the arcuate front edge of the seat adjustment plate 124. The adjustment apertures 130 may be oblong or stadium-shaped inform with a longitudinal axis of each adjustment aperture 130 aligned with a radius from the first pivot point.

[0033] In the example implementation in the figures, the articulating arm 106 is formed as a box frame structure with opposing, longitudinally extending sidewalls 132a / b, a top plate 134, and a bottom plate 138 all welded together. The top plate 134 defines a longitudinal top slot 136 along a majority of its length from adjacent to a front end to adjacent to a rear end. Similarly, the bottom plate 138 defines a longitudinal bottom slot 140 along a majority of its length from adjacent to a front end to adjacent to a rear end. The top plate 134 and the bottom plate 138 can each include a plurality of laterally extending tabs that seat respectively within a corresponding plurality of shallow rabbets formed within top and bottom edges of the sidewalls 132a / b for added rigidity. Additionally, several cross members 133 can extend normally from interior sides of the sidewalls 132a / b and span between them for added structural support. The cross members 133 may be fixed to the sidewalls 132a / b, e.g., by welding. The cross members 133 may include lateral tabs that extend through corresponding openings within the sidewalls 132a / b for aid in alignment and added stability

[0034] A rear end of the articulating arm 106 can connect to the seat adjustment plate 124 at the first pivot point. The sidewalls 132a / b at the rear end of the articulating arm 106 extend on either side of the seat adjustment plate 124 and form rear shoulders 142a / b for connection with the seat adjustment plate 124. The rear edges of the top plate 134 and the bottom plate 138 may both define cutout recesses to provide clearance for the front edge of the seat adjustment plate 124 as it pivots. The seat adjustment plate 124 may define a bore at the first pivot point which receives a rear bearing housing 144 that seats between the rear shoulders 142a / b. The rear pivot shafts 146a / b, which in the present design are threaded bolts, extend through the rear shoulders 142a / b to connect with a dual end, female-threaded axle 145 that functions as a blind nut for each of the rear pivot shafts 146a / b. The rear bearing housing144 extends around the axle 145 and the bearings (not visible) in the rear bearing housing 144 rotate about the axle 145 to provide smooth rotation of the seat adjustment plate 124 about the axle 145.

[0035] The mounting mechanism 105 is positioned at a front end of the adjustable seat device 100 opposite the seat 102 and is attached to a front end of the articulating arm. The mounting mechanism 105 comprises several different components, all made of steel plate or steel square tube in this implementation, including a frame mount channel 164, an offset mount 160, a receiver post 158, a reinforcing bracket 156, a pivot bracket 162, and a height adjustment plate 150. The frame mount channel 164 (also called a “C-cup” in the fitness equipment industry) is provided for attachment of the adjustable seat device 100 to a vertical frame member 170 (e.g., steel square tube) of a frame or cage of a strength training deviceas further described below. The offset mount 160 is fixed (e.g., by a weld) to the rear surface of the frame mount channel 164 and extends rearward therefrom at a slight upward angle from the horizontal. The receiver post 158 is fixed (e.g., by a weld) to the rear end of the offset mount 160 and extends vertically upward therefrom. The receiver post 158 supports the leg rollers 104a / b, as further described below, and the offset mount 160 provides clearance between the receiver post 158 and the frame mount channel 164 for the leg rollers 104a / b.

[0036] A reinforcing bracket 156 is formed as a U-shaped band and extends about three sides of the receiver post 158 above the offset mount 160. The front edges of the parallel sides of the reinforcing bracket 156 are fixed (e.g., by welds) to the rear side of the frame mount channel 164. The reinforcing bracket 156 can further be fixed (e.g., by welds) to the receiver post 158 along adjoining edges and can also be fixed (e.g., by welds) along bottom edges to the offset mount 160. A pivot bracket 162 is formed of two parallel sidewalls connected (e.g., by welds) by a mount tube 168 extending therebetween. Corresponding apertures can be formed in the parallel sidewalls of the pivot bracket 162 at the interface with the edges of the lower mount tube 168 to expose a cylindrical channel 166 across and between the sidewalls of the pivot bracket 162. The pivot bracket 162 seats beneath the offset mount 160 and adjacent to the rear wall of the frame mount channel 164. The top edges of the sidewalls of the pivot bracket 162 can be fixed (e.g., by welds) to a bottom surface of the offset mount 160. Similarly, the front edges of the sidewalls of the pivot bracket 162 can be fixed (e.g., by welds) to the rear wall of the frame mount channel 164.

[0037] The height adjustment plate 150 is fixed to (e.g., by welds) and extends normally from a rear wall of the reinforcing bracket 156 in a vertical plane. The rear wall of the reinforcing bracket 156 may extend downward along the receiver post 158 below its sidewalls to provide a greater length dimension for interfacing with the height adjustment plate 150. In some example implementations, the reinforcing bracket 156 may define one or more slots in its rear face for receiving corresponding tabs (not visible) extending from the front edge of the height adjustment plate 150 for purposes of alignment and greater strength at the interface between the two. The rear edge of the height adjustment plate 150 is arcuate in form and extends downward at a radius from a second pivot point (indicated by front pivot shafts 149a / b) to a pointed bottom end. (In this example, the height adjustment plate 150 has a similar form to the neck, head, and beak of a bird pecking toward the ground.)

[0038] The height adjustment plate 150 defines a plurality of adjustment apertures 152 along an arcuate path adjacent to the arcuate rear edge of the height adjustment plate 150. The adjustment apertures 152 may be oblong or stadium-shaped in form with a longitudinal axis of each adjustment aperture 152 aligned with a radius from the second pivot point. Inone example implementation, considering the lowest adjustment aperture to provide a 0° reference, three additional adjustment apertures 152 can be provided at 12.5°, 25°, and 40° offsets angularly above the lower, 0° reference adjustment aperture. The rear portion (the bird head) of the height adjustment plate 150 extends through each of the top slot 136 in the top plate 134 of the articulating arm 106 and bottom slot 140 in the bottom plate 138 of the articulating arm 106. Depending upon the position of the articulating arm 106, greater or lesser portions of the height adjustment plate 150 will extend above and below the articulating arm 106 in a particular configuration.

[0039] A front end of the articulating arm 106 can connect to the height adjustment plate 150 at the first pivot point. The sidewalls 132a / b at the front end of the articulating arm 106 extend on either side of the height adjustment plate 150 and form front shoulders 148a / b for connection with the height adjustment plate 150. The height adjustment plate 150 may define a bore at the second pivot point which receives a front bearing housing 165 that seats through corresponding opposing bores in the pivot bracket 162 aligned between the front shoulders 148a / b. The front pivot shafts 149a / b, which in the present design are threaded bolts, extend through the front shoulders 148a / b to connect with a dual end, female-threaded axle 167 that functions as a blind nut for each of the front pivot shafts 149a / b. The front bearing housing165 extends around the axle 167 and the bearings 148a / b (see FIG. 6) in the front bearing housing 165. The articulating arm 106 can thereby smoothly rotate about the axle 167with respect to the pivot bracket 162, and thus the entirety of the mounting mechanism 105, when manipulated by a user.

[0040] Each of the seat adjustment plate 124 and the height adjustment plate 150 are releasably held in place by a fastening mechanism, for example, a seat adjuster pop-pin 230 and a height adjuster pop-pin 244, respectively. Both pop-pins 230, 244 are designed and operate the same in the example implementation. The components and functionality of the seat adjuster pop-pin 230 is shown in FIG. 5. The components and operation of the height adjuster pop-pin 244 are identical thereto and reference to the seat adjuster pop-pin 230 in the following discussion will be made merely to pop-pin 230 for ease and cross-application of the description.

[0041] The seat adjuster pop-pin 230 is mounted to the left sidewall 132b of the articulating arm 106 in an intermediate location along the articulating arm 106 between the first and second pivot points. The components of the seat adjuster pop-pin 230 are best presented in cross section in FIG. 5. The seat adjuster pop-pin 230 includes a knob 232 that is attached to a locking pin 234 seated within a pin housing 236. The pin housing 236 is formed as a cylindrical protrusion from the left sidewall 132b of the articulating arm 106 anddefines a cavity 240 therein in which the locking pin 234 resides. The pin housing 236 further surrounds an opening 239 in the right sidewall 132a of the articulating arm 106. A flange 235 is formed about an outer surface of the locking pin 234 toward a first end distal from the knob 232. The locking pin 234 also has a threaded second end 233 that interfaces with a threaded blind bore hole in the knob 232. A threaded housing cap 238 screws into the pin housing 236 and defines an aperture therein through which the locking pin 234 extends to connect with the knob 232. A spring 242 fits about the shaft of the locking pin 234 and seats against the flange 235 at a first end. At a second end, the spring 242 seats against the interior side of the threaded housing cap 238. The interface between the threaded second end 233 of the locking pin 234, the knob 232, and the housing cap 238 resists the bias of the spring 242 and retains the locking pin 234 within the cavity 240.

[0042] The spring 242 biases the locking pin 234 toward the left sidewall 132b and the first end of the locking pin 234 beyond the flange 235 extends through and beyond the opening 239 in the left sidewall 132b to interface discretely with the adjustment apertures 130 in the seat adjustment plate 124 as it is pivoted to different angular positions about the first pivot point. Similarly, a locking pin 246 (see FIG. 4) of the height adjuster pop-pin 244, positioned in an intermediate location along the articulating arm 106 between the first and second pivot points, extends through and beyond a second opening in the left sidewall 132b to interface discretely with the adjustment apertures 152 in the height adjustment plate 150 as it is pivoted to different angular positions about the second pivot point.

[0043] As shown to best advantage in FIG. 3, the seat adjustment plate 124 supports a rear glide plate 125 on the left side interposed between the left sidewall 132b of the articulating arm 106 and the seat adjustment plate 124. The rear glide plate 125 may be a planar polyurethane liner with apertures formed therein aligned with and sized to mirror the adjustment apertures 130 in the seat adjustment plate 124. The rear glide plate 125 may be affixed to the seat adjustment plate 124 with set screws for easy removal and replacement. The rear glide plate 125 may be beneficial to reduce any friction and wear between the locking pin 234 in the seat adjuster pop-pin 230 and the seat adjustment plate 124 as the locking pin 234 is biased toward the seat adjustment plate 124 when the seat is angularly adjusted. If the rear glide plate 125 becomes excessively worn, it can be replaced.

[0044] Similarly, as shown in FIG. 3, the height adjustment plate 150 supports a front glide plate 154 on the left side interposed between the left sidewall 132b of the articulating arm 106 and the height adjustment plate 150. The front glide plate 154 may be a planar polyurethane liner with apertures formed therein aligned with and sized to mirror the adjustment apertures 152 in the height adjustment plate 150. The front glide plate 154 may be affixed to the height adjustment plate 150 with set screws for easy removal andreplacement. The front glide plate 154 may be beneficial to reduce any friction and wear between the locking pin 246 in the height adjuster pop-pin 244 and the height adjustment plate 150 as the locking pin 246 is biased toward the height adjustment plate 150 when the articulating arm 106 is angularly adjusted. If the front glide plate 154 becomes excessively worn, it can be replaced.

[0045] Additionally, the seat adjustment plate 124 includes a range of motion stopper 127 at the lower end of the array of adjustment apertures 130. The stopper 127 can simply be a bolt extending through the seat adjustment plate 124 and fastened with a nut, but other structures are possible, e.g., pins or posts fixed to the sidewalls of the seat adjustment plate 124. The stopper 127 prevents the seat 102 from rotating beyond the range of the adjustment apertures 130. If the seat adjuster pop-pin 230 is disengaged from the lowest of the adjustment apertures 130 and the seat 102 continues to rotate counterclockwise upward (when viewed from the left side) about the first pivot point, the stopper 127 will engage with the bottom plate 138 of the articulating arm 106, thereby preventing further rotation of the seat 102). The seat mounting plate 122 acts as a range of motion stop in the clockwise direction (when viewed from the left side) as it interfaces with the top plate 134 of the articulating arm 106 when the seat adjuster pop-pin 230 is in the upper most of the adjustment apertures 130.

[0046] The height adjustment plate 150 similarly includes two range of motion stops, a lower stopper 153 and an upper stopper 157. Both can simply be bolts extending through the height adjustment plate 150 and fastened with nuts, but other structures are possible, e.g., pins or posts fixed to the sidewalls of the height adjustment plate 150. The stoppers 153,157 prevent the articulating arm 106 from rotating beyond the range of the adjustment apertures 152 in the height adjustment plate 150. If the height adjuster poppin 244 is disengaged from the lowest of the adjustment apertures 152 and the articulating arm 106 continues to rotate counterclockwise downward (when viewed from the left side) about the second pivot point, the lower stopper 153 will engage with the bottom plate 138 of the articulating arm 106, thereby preventing further rotation of the articulating arm 106. The upper stopper 157 similarly acts as a range of motion stop in the clockwise direction (when viewed from the left side) as it interfaces with the top plate 134 of the articulating arm 106 when the height adjuster pop-pin 244 is removed from the uppermost of the adjustment apertures 152.

[0047] As indicated above, in the example implementation, the mounting mechanism 105 is configured to support a pair of leg rollers 104a / b on a mounting structure as best understood in the cross section of FIG. 5. Each leg roller 104a / b may be composed of a thick-walled foam cylinder 208a / b concentrically seated over rigid roller shafts 218a / b, e.g., formed from steel tubing. Inner roller caps 210a / b in the form of annular disks can bepositioned about the inner ends of the roller shafts 218a / b and held in place by collets 212a / b fastened to the inner ends, e.g., with set screws 214, to prevent inward migration of the foam cylinders 208a / b along the roller shafts 218a / b. A female connector 220 can be fixedly mounted within and extend from an inner end of a first of the roller shafts 218a. A corresponding male connector 222 can be fixedly mounted within and extend from an inner end of a second of the roller shafts 218b. The female and male connectors 220, 222 can be cooperating cylindrical plugs, the female connector 220 defining a threaded blind hole in an end and the male connector 222 defining a corresponding threaded shaft sized to mate with the threaded blind hole. Using these corresponding structures, the roller shafts 218a / b, and thus the leg rollers 104a / b, can be releasably, axially connected to each other.

[0048] Each outer end of foam cylinders 208a / b of the leg rollers 104a / b may define an annular recess with walls angled annularly inward toward the roller shafts 218a / b, thus creating a cavity at each outer end. Annular roller end liners 224a / b, e.g., of a molded plastic construction, can be formed to seat within the cavity and abut the angled interior surfaces of the foam cylinders 208a / b and extend a sort distance along the outer walls of the roller shafts 218a / b as depicted. The roller end liners 224a / b may be adhered or otherwise affixed to the foam cylinders 208a / b and / or the outer walls of the roller shafts 218a / b.Flange plates 219a / b can be fixed to the outer ends of the roller shafts 218a / b, with the diameter of the flange plates 219a / b extending over an annular base wall of the roller end liners 224a / b. The flange plates 219a / b can define apertures in the centers thereof opening to the passage within the roller shafts 218a / b. Respective blind nuts 226a / b can be fixed to the inner sides of the flange plates 219a / b to seat axially within the roller shafts 218a / b. The flange plates 219a / b may further define one or more threaded apertures radially beyond the center apertures.

[0049] Roller end caps 192a / b can be configured to seat within the end cavities in the foam cylinders 208a / b adjacent to the roller end liners 224a / b and the flange plates 219a / b. The roller endcaps 192a / b can be molded plastic inserts defining a cavity with angled annular sidewalls. A molded butterfly finger-turn 194a / b can be formed diametrically across the roller endcaps 192a / b. Apertures can be formed in a center of the butterfly fingerturns 194a / b for receiving bolts 228a / b therethrough that interface with the blind nuts 226a / b within the roller shafts 218a / b. The bolts 228a / b can be tightened to fix the roller endcaps 192a / b to the roller shafts 218a / b. Additional apertures can be formed in a base wall of the roller end caps 192a / b aligned with the one or more threaded apertures in the flange plates 219a / b. Once the roller endcaps 192a / b are affixed by the bolts 228a / b, set screws 229 can be used to fix the base of the roller endcaps 192a / b to the flange plates 219a / b to prevent the end caps 192a / b from overtightening or loosening when a userengages the butterfly finger-turns 194a / b. The butterfly finger-turns 194a / b can be grasped and turned by a user to engage and disengage the roller shafts 218a / b from each other by translating force down the roller shafts 218a / b to the female and male connectors 220, 222.

[0050] The leg rollers 104a / b can primarily seat within a transverse tube 216 seated at the top end of a roller post 196 forming part of the mounting structure. The roller post 196 can be a length of square steel tubing with lateral apertures in opposing sidewalls through which the transverse tube 216 is placed and fixed (e.g., by welds). The female and male connectors 220, 222 extend from the ends of the roller shafts 218a / b and connect within the transverse tube 216. The ends of the roller shafts 218a / b abut the lateral ends of the transverse tube 216 and edges of the collets 212a / b may assist in aligning the ends of the transverse tube 216 and the roller shafts 218a / b as depicted in FIG. 5. When the user grasps the butterfly finger-turns 194a / b and turns the roller shafts 218a / b, the female and male connectors 220, 222 interlock within the transverse tube 216 and the inner ends of the roller shafts 218a / b firmly seat against the ends of the transverse tube 216.

[0051] The roller post 196 extends vertically downward from the transverse tube 216 forming an opposing portion of the mounting structure and allows for height adjustment of the leg rollers 104a / b. A rear wall of the roller post 196 defines a vertical array of adjustment apertures 197. A front wall of the roller post defines a vertical channel 202 (as indicated in FIG. 4) along most of its length. The cross-sectional dimensions of the roller post 196 are selected such that the roller post 196 can slidingly fit within the receiver post 158 with close tolerances (i.e. , with little “slop”). A receiver post pop-pin 198 is mounted at an upper location on the rear wall of the receiver post 158. The receiver post pop-pin 198 can be of the same design and have the same functionality of the seat adjuster pop-pin 230 previously described herein. The locking pin 199 of the receiver post pop-pin 198 passes through an aperture in the rear wall of the receiver post 158 and is biased to engage with the adjustment apertures 197 within the roller post 196.

[0052] A post handle 110 may be mounted to the top of the roller post 196. In this example implementation, the post handle 110 is fastened to a bolt plate 206 fixed (e.g., by a weld) to the top of the roller post 196. An aperture in a base web of the post handle 110 may seat over a threaded bolt 207 extending from the bolt plate 206 and a thumb nut 204 positioned within the handle can be tightened to fasten the post handle 110 to the bolt 207 on the bolt plate 206. The post handle 110 can be grasped by a user in one hand to lift the leg rollers 104a / b attached to the roller post 196 up and down. The user can use a second hand to pull the receiver post pop-pin 198 outward against the spring bias to remove the locking pin 199 from one of the adjustment apertures 197, thereby allowing for free vertical movement and adjustment of a height of the leg rollers 104a / b to any one of the adjustment apertures 197. A set bolt 200 (see FIG. 4) may be fastened through a threaded aperture in afront wall of the receiver post 158. The internal end of the set bolt 200 may extend through and reside within the vertical channel 202 in the front wall of the roller post 196. The set bolt 200 thus interfaces with a bottom edge of the vertical channel 202 and prevents the roller post 196 from being fully removed from the receiver post 158 (unless the set bolt 200 is removed).

[0053] The adjustable seat device 100 can be mounted to a vertical frame member 170 of a strength training device via the U-shaped frame mount 164. This is best depicted in FIGS. 3, 4, and 7. The frame mount 164 defines a channel 180 open to the front side of the adjustable seat device 100 that receives the vertical frame member 170 therein. A hanger shaft 172 extends normally from an interior face of the rear wall of the frame mount 164. The hanger shaft 172 can have a stepdown shoulder that extends through an aperture of corresponding diameter within the rear wall of the frame mount 164 and a threaded shaft 173 that extends beyond the rear wall to interface with a nut 174 that securely fastens the hanger shaft 172 to the frame mount 164. To install the adjustable seat device 100 on a vertical frame member 170, the user can grasp the adjustable seat device 100 by the seat handle 108 fixed to the offset mount 160, e.g., by welds between the handle mounts 109 on either side thereof, with one hand, and grasp the seat pull 120 at the rear end 118 of the seat 102 in the other hand to fit the channel 180 about the vertical frame member 170 and insert the hanger shaft 172 through standard opposing bolt apertures along lengths of opposing walls of the vertical frame member 170. Alternatively, the user can grasp the adjustable seat device 100 by the seat handle 108 and the post handle 110 to similarly manipulate the adjustable seat device 100 onto the vertical frame member 170.

[0054] Once the hanger shaft 172 is placed through the bolt holes in the vertical frame member 170, the frame mount channel 164 can be fully secured to the vertical frame member 170 by inserting a transverse locking shaft 176 through opposing lateral holes in the sidewalls of the frame mount channel 164 and through opposing aligned lateral holes in the sidewalls of the vertical frame member 170. The locking shaft 176 may have a threaded end 177 attached to a shaft knob 178 for ease of insertion and removal of the locking shaft 176 within the frame mount channel 164. The shaft knob 178 may further include several magnets 179 embedded in a base surface thereof that bias and hold the shaft knob 178 to the sidewall of the frame mount channel 164 to maintain the locking shaft 176 in place, while still providing for easy removal.

[0055] For ease of attachment to the vertical frame member 170, a certain amount of “slop” or “gap” is required in the frame mount channel 164 to ensure the frame mount channel 164 can fit around different vertical frame members 170 that may have slightly different dimensional tolerances. However, for the adjustable seat device 100, any amount of “slop” will make the seat 102 feel wobbly, unstable, or cheap when performing exerciseson it. To address the “slop”, a set of liners, e.g., a lower liner plate 184, a rear liner plate 186, and an opposing liner plate 188, is provided within the frame mount channel 164 to absorb some of the gap while reducing the clatter of metal on metal when attaching the frame mount channel 164 to the vertical frame member 170. The liner plates 184, 186, 188 may be planar plastic (e.g., polyurethane) pieces attached to the inner walls of the frame mount channel 164 with set screws.

[0056] An additional clamping liner plate 182, in this example positioned above the lower liner plate 184 on one of the sidewalls, may be formed as a steel plate coated with a layer of plastic (e.g., polyurethane). A top edge of the clamping liner plate 182 may be attached to the sidewall of the frame mount channel 164 with set screws with the bottom end free. An accompanying adjustment mechanism can be used to push the bottom portion of the clamping liner plate 182 inward in direction D to clamp the vertical frame member 170 against the opposing liner plate 188 within the frame mount channel 164. In one example implementation, a thumbscrew composed of a knob 190 attached to a threaded shaft 191 seats within a threaded aperture 189 in a sidewall of the frame mount channel 164. A user can turn the knob 190 to tighten the clamping liner plate 182 and remove any excessive gap, eliminating wobble. In another example implementation, the clamping liner plate 182 is not attached to the inner sidewall with set screws, but instead two thumbscrews are provided to evenly push the top and bottom of the clamping liner plate 182 against the vertical frame member 170.

[0057] FIGS. 8-10 show three further example configurations of the seat 102 of the adjustable seat device 100 when the seat adjustment plate 124 and the height adjustment plate 150 are positioned at different adjustment apertures 130, 152, respectively. It should be understood that these examples are not representative of all possible positions, heights, or angles of the seat 102 and many other permutations are possible depending upon the combination of adjustment apertures 130, 152 selected. It is notable, however, that the stadium shape of each of the adjustment apertures 130, 152 allows for receipt of the locking pins 234, 246 of the pop-pins 230, 244 in any of the combinations. It may further be appreciated that there is corresponding adjustment aperture 130 in the seat adjustment plate 124 that will adjust the top surface 112 of the seat 102 to a horizontal plane for each position of the adjustment apertures 152 in the height adjustment plate 150. Further, it may be appreciated that a combination of locking the seat-adjuster pop-pin 230 in the lowest of the adjustment apertures 130 in the seat adjustment plate 124 and locking the height adjuster pop-pin 244 in the highest of the adjustment apertures 152 in the height adjustment plate 150 will adjust the top surface 112 of the seat 102 to orient vertically, i.e., in a vertical plane.

[0058] Finally, as noted, the leg rollers 104a / b may be removed from the roller post 196 by unscrewing the female and male connectors 220, 222 from each other. This allows the leg rollers to be attached to any vertical frame member 170 in a strength training device to use in performance of different exercises. In addition, the roller shafts 118a / b may be placed within the lower mount tube 168 through the openings 166 if desired for a very low and slightly forward mounting position, which may be desirable for providing arm rests for seated free weight exercises.

[0059] In view of the above description, it can be understood that in one example implementation, an adjustable seat for a strength training device includes a seat and a mounting mechanism for attachment of the adjustable seat to the strength training device. The seat defines a top surface and a bottom surface. A seat adjustment plate is mounted to the bottom surface of the seat. A height adjustment plate is connected to the mounting mechanism. An articulating arm is disposed between and connected at a first end to the seat adjustment plate at a first pivot point and connected at a second end to the mounting mechanism at a second pivot point. A first adjustment mechanism is interposed between the seat adjustment plate and the articulating arm and is adjustable to pivot the seat about the first pivot point with respect to the articulating arm. A second adjustment mechanism is interposed between the height adjustment plate and the articulating arm and is adjustable to pivot the seat about the second pivot point with respect to the mounting mechanism.

[0060] In another example implementation of the adjustable seat, the height adjustment plate is connected at a first end to the mounting mechanism apart from the second pivot point and is releasably connected at a second end to an intermediate location on the articulating arm by the second adjustment mechanism to support a height position of the articulating arm as the articulating arm pivots about the second pivot point.

[0061] In another example implementation of the adjustable seat, the seat adjustment plate is releasably connected by the first adjustment mechanism to an intermediate location on the articulating arm apart from the first pivot point to support an angular orientation of the top surface of the seat as the seat pivots about the first pivot point.

[0062] In another example implementation of the adjustable seat, an angular orientation of the top surface of the seat with respect to the mounting mechanism is adjustable with respect to both the first pivot point and the second pivot point.

[0063] In another example implementation of the adjustable seat, the seat adjustment plate is adjustable in first discrete angular increments with respect to the first pivot point, the articulating arm is adjustable in second discrete angular increments with respect to the mounting mechanism, and a combination of each of the second angular increments with a corresponding one of the first discrete angular increments results in respective configurations in which the top surface of the seat is horizontally oriented.

[0064] In another example implementation of the adjustable seat, the seat adjustment plate is adjustable in first discrete angular increments with respect to the first pivot point, the articulating arm is adjustable in second discrete angular increments with respect to the mounting mechanism, and a combination of one of the second angular increments with a corresponding one of the first discrete angular increments results in a configuration in which the top surface of the seat is vertically oriented.

[0065] In another example implementation, the adjustable seat can further include a handle mounted to the mounting mechanism above the height adjustment plate.

[0066] In another example implementation of the adjustable seat, the mounting mechanism defines a channel configured to seat about a frame member of a framework of the strength training device. A liner plate extends along an interior wall of the channel. An adjustment device connects between the mounting mechanism and the liner plate to adjustably move the liner plate away from and toward the interior wall of the channel.

[0067] In another example implementation of the adjustable seat, the liner plate is an elongated planar structure. The liner plate is attached to the interior wall at a first end. The adjustment device interacts with the liner plate to move a second, free end of the liner plate with respect to the interior wall of the channel.

[0068] In another example implementation of the adjustable seat, the liner plate is constructed of two layers, namely, a metal layer positioned against the interior wall of the channel, and a plastic layer bonded to the metal layer and facing into the channel.

[0069] In another example implementation, the adjustable seat can further include a pair of leg rollers and a height-adjustable mounting structure for removable connection of the leg rollers to the mounting mechanism.

[0070] In another example implementation of the adjustable seat, the leg rollers are longitudinally aligned along a common axis and are removably attached to the mounting structure.

[0071] In another example implementation of the adjustable seat, the leg rollers are mounted to the mounting mechanism via the height-adjustable mounting structure positionally above the height adjustment plate.

[0072] In another example implementation of the adjustable seat, a handle is mounted to a top end of the height-adjustable mounting structure.

[0073] In another example implementation, the adjustable seat can further include a retainer that interfaces between the mounting mechanism and the height-adjustable mounting structure and is configured to allow for movement of the leg rollers with respect to the mounting mechanism while providing a stop preventing removal of the leg rollers from the mounting mechanism unless the retainer is removed from the mounting mechanism.

[0074] In a further example implementation of the adjustable seat, the mounting mechanism is configured for adjustable and removable attachment to a fenestrated vertical member of the strength training device directly at discrete positions along a length of the fenestrated vertical member.

[0075] Additionally, in view of the above description, it can be understood that in another example implementation, an adjustable seat for a strength training device includes a seat and a mounting mechanism for attachment of the adjustable seat to the strength training device. An articulating arm is pivotably connected at a first end to the seat at a first pivot point and pivotably connected at a second end to the mounting mechanism at a second pivot point. The seat is adjustable in first discrete angular increments with respect to the first pivot point. The articulating arm is adjustable in second discrete angular increments with respect to the mounting mechanism.

[0076] In another example of the adjustable seat, a combination of each of the second angular increments with a corresponding one of the first discrete angular increments results in respective configurations in which the seat is horizontally oriented.

[0077] In another example of the adjustable seat, a combination of one of the second angular increments with a corresponding one of the first discrete angular increments results in a configuration in which the seat is vertically oriented.

[0078] In another example of the adjustable seat, an angular orientation of the seat with respect to the mounting mechanism is adjustable with respect to both the first pivot point and the second pivot point.
