TECHNICAL FIELD
The present invention relates to a glute press exercise machine in which a reclining user pushes their lower torso forwards to lift a weight.
BACKGROUND OF THE INVENTION
Existing glute press weight lifting machines typically provide support to a reclining user and use a rotating arm attached to the frame of the device that is positioned across the user's abdomen. As the user pushes their hips/abdomen upwards, they thereby move the rotating arm which in turn pulls on a cable to lift a weight stack.
Other glute press exercises have been developed that do not rely on specialized equipment. For example, a user can simply rest their upper back or shoulders on or against a standard lifting bench, and then place a weight bar across their hips/abdomen. Next, the user proceeds to lift the weight bar by straightening their legs/back. Unfortunately, the disadvantage of this approach is that it provides very poor support to the user's back during the exercise.
What is instead desired is a simple, effective and comfortable machine for performing glute presses. Ideally, such a machine would not rely on movement of the user to rotate an exercise arm during the exercise.
Ideally as well, it would be desirable to provide a glute press exercise machine that supports a user's lower back and hips throughout the movement of the full glute press exercise.
SUMMARY OF THE INVENTION
In preferred aspects, the present system provides a glute press exercise machine, comprising: a stationary frame; a four-bar linkage (or multi-bar linkage) connected to the stationary frame; a rotatable back support connected to the four-bar linkage; a seat connected to at least one of the bars of the four-bar linkage; a foot support connected to the stationary frame; and an abdomen restraint connected to the back support.
The rotatable back support has an upper portion and a lower portion with the lower portion extending down below the user's hips to support the user's hips during the full glute press exercise. Preferably, the lower portion of the rotatable back support supports at least 10% of the user's total body weight such that the user's total body weight is not solely supported by the user's upper back and feet.
Preferably as well, the seat rotates downwardly away from the user's hips during a glute press exercise and then rotates upwardly again to contact the user's bottom between every repetition of glute press exercises.
Preferably, the four-bar (or multi-bar) linkage is pivotally connected to the stationary frame at a location near the ground level and the bars of the four-bar linkage each rotate between different non-vertical angles during a glute press exercise.
In preferred aspects, the foot support is positioned below 25 cm from the ground and the foot support extends forwardly beyond the front of the stationary frame.
Preferably, a cable connecting the rotatable back support to a weight stack assembly passes through a frame member that spans along the ground extending from a location mid-way along the stationary frame to the weight stack assembly. An optional horizontal stabilizing arm connects the weight stack assembly to a rear portion of the stationary frame.
In alternate preferred embodiments, the present system provides a hip-thrust exercise machine, comprising: a frame; a back support pivotally connected to an upper portion of the frame; a seat and foot support pivotally connected to a lower portion of the frame; and an abdomen restraint connected to the back support, wherein a user pushes the abdomen restraint upwards, tilts the back support backwards and tilts the seat and foot support forwards when the user thrusts their hips forward.
In further alternate preferred embodiments, the present system provides a hip-thrust exercise machine, comprising: a frame; a back support pivotally connected to an upper portion of the frame; a foot support pivotally connected to a lower portion of the frame; an elongated member connecting the back support to the foot support; and an abdomen restraint connected to the back support, wherein a user pushes the abdomen restraint upwards, tilts the back support backwards when the user thrusts their hips forward.
In further alternate embodiments, the present system provides a glute press exercise machine in which a moveable support connected to the stationary frame supports a rotatable back support which rotates around an axis that moves forwards as the user tilts the back support backwards during an exercise. In this embodiment, a support member may connect the abdomen restraint to the stationary frame, and the stationary frame, moveable support, abdomen restraint and support member together form a four-bar linkage. In addition, the moveable support is preferably positioned underneath of the rotatable back support.

DETAILED DESCRIPTION OF THE DRAWINGS
FIGS. 1 to 11 show a first embodiment of a glute press exercise machine 10, comprising: a stationary frame 12; a four-bar linkage 20; a rotatable back support 14; a seat 17; a foot support 18 and an abdomen restraint 20. Rotatable back support 14 optionally has an upper portion 14A and a lower portion 14B. Lower portion 14B extends below the user's hips to support the users hips during a glute press exercise (as can be seen in FIG. 8). As can be seen in FIGS. 8 and 9, lower portion 14B of rotatable back support 14 preferably extends below the user's hips before, during and after each repetition of the glute press exercise.
In preferred aspects, lower portion 14B of rotatable back support 14 supports a portion of the user's weight. Most preferably, lower portion 14B supports at least 10% of the user's total body weight such that the user's total body weight is not solely supported by the user's upper back and feet. As can be seen best in FIG. 1, lower portion 14B of back support 14 can optionally be angled with respect to the upper portion. In preferred aspects, this angle is 5 to 10 degrees. In one exemplary embodiment, this angle is 7 degrees. The angling of lower portion 14B under the user's hips optionally assists in providing support under the user's hips to thereby support the user's hips. As can also be seen in FIG. 1, the upper and lower portions 14A and 14B of back support 14 are preferably formed as a continuous one-piece device.
As seen by comparing FIGS. 8 and 9, seat 17 rotates downwardly away from the user's hips during a glute press exercise and then rotates upwardly again to contact the user's bottom between each exercise repetition. As a result, seat 17 preferably contacts the user's bottom between every repetition of glute press exercises such that the user sits on seat 17 between every repetition of glute press exercises.
The four-bar linkage 20 preferably comprises four bars that are pivotally connected to the stationary frame at locations near ground level. Specifically, four-bar linkage 20 comprises two forward bars 22 and two rearward bars 24. Forward bars 22 are connected to frame 12 at pivot point 23 (right near ground level) and rearward bars 24 are connected to frame 12 at pivot point 24 (also right near ground level). As a result of back support 14 being mounted onto four-bar linkage 20 (at pivot points 23 and 25), back support 14 rotates about a horizontal axis H (see FIGS. 10 and 11) that does not pass through the stationary frame 12.
Seat 17 is preferably connected onto forward bars 22. As best seen in FIGS. 8 to 11, bars 22 and 24 each rotate between different non-vertical angles during a glute press exercise. As such, at no time during the exercise do bars 22 and 24 point straight up and down in a vertical direction. Rather, each of the four bars rotate 22 and 24 between angles of at least 40 degrees to the ground to not more than 80 degrees to the ground during a glute press exercise. Specifically, forward bars 22 rotate between an angle of about 50 to 80 degrees to the (horizontal) ground, and rearward bars 24 rotate between an angle of about 45 to 75 degrees to the (horizontal) ground.
As can also be seen, foot support 18 is also positioned close to the ground. In preferred embodiments, foot support 18 is positioned at a height of less than 25 cm from the ground. As can also be seen, foot support 18 extends forwardly beyond the front of stationary frame 12.
Abdomen restraint 20 preferably comprises a padded arm 22 that is positionable against the user's abdomen. Padded arm 22 is preferably moveable in a direction that is generally perpendicular to the back support. As such, padded arm 22 moves in a direction towards and away from the user's abdomen (i.e.: from a “far away” position to the illustrated “resting against the abdomen” position in FIGS. 8 and 9). As a result, abdomen restraint 20 and padded arm 22 prevents the user from slipping upwardly on back support 14 during a glute press exercise. As a result, abdomen restraint 20 preferably keeps the user's bottom on seat 17 at the start of the glute press exercise (FIG. 8), until seat 17 drops away from the user's bottom as the user performs the glute press (FIG. 9).
In preferred aspects, the present system further comprises: a weight stack assembly 40; and a cable connecting rotatable back support 14 to weight stack assembly 40. As the user rotates rotatable back support 14, the cable is pulled, thereby lifting one or more weights in weight stack assembly 40.
In preferred aspects, the cable passes through a frame member 50 that spans along the ground between the stationary frame 12 and the weight stack assembly 40. As seen in FIG. 5, frame member 50 preferably extends along the ground from a location mid-way along stationary frame 12 (i.e.: neither at the front or back of frame 12). As such, the present glute press exercise can be used to lift a stack of several weights in weight stack 13. In preferred aspects, a cable mount is provided on the bottom back of back support 14 for attachment of the cable thereto.
In addition, a stabilizing arm 60 preferably connects weight stack assembly 10 to a rear portion of stationary frame 12. As can be seen, distal end 61 of stabilizing arm 60 may simply rest upon the top of a support 19 at the rear portion of stationary frame 12. As can also be seen, stabilizing arm 60 preferably extends horizontally between weight stack assembly 40 and stationary frame 12.
In preferred aspects, abdomen restraint 20 is moveable in a direction generally perpendicular to back support 14. As such, abdomen restraint 20 preferably comprises a padded arm 22 that is moveable towards and away from the user's abdomen. In optional aspects of the present system, abdomen restraint 20 may be connected to back support 14 by a four-bar linkage 70. Other systems for moving padded arm 22 towards and away from the user's abdomen are also contemplated, all keeping within the scope of the present invention.
In operation, as shown in FIG. 8, the user sits down on seat 17 and then moves padded arm 22 into a position against their abdomen. Next, as shown in FIG. 9, the user straightens their legs, simultaneously lifting padded arm 22 while tilting back support 14 backwards as the user's hips move forward. The rearward rotation of rotatable back support 14 preferably pulls on a cable to lift one or more weights within weight stack assembly 40. Alternatively, however, the rearward rotation of rotatable back support 14 could also rotate an arm or activate a mechanical linkage that would also lift a weight, all keeping within the scope of the present invention.
FIG. 10 is a view corresponding to FIG. 8, showing rotational movement of the system about horizontal rotational axis H (such that back support 14 rotates about axis H). FIG. 11 is a view corresponding to FIG. 9, also showing horizontal rotational axis H of the machine. As can be seen, horizontal rotational axis H does not pass through back support 14.
FIG. 12 is a side elevation view of a second embodiment of the present system, prior to a user performing a hip-thrust exercise. Specifically, FIG. 12 shows a hip-thrust exercise machine 100, comprising: a frame 112; a back support 114 pivotally connected to an upper portion of frame 112; a seat and foot support 116 pivotally connected to a lower portion of frame 112; and an abdomen restraint 120 connected to back support 114.
Abdomen restraint 120 comprises a padded arm 122 that is positionable against the user's abdomen. Specifically, padded arm 122 is in a direction generally perpendicular to the back support in a direction towards and away from the user's abdomen (i.e.: from a “far away” position to the illustrated “resting against the abdomen” position). After the user sits down on seat 117 (FIG. 12), the user then moves padded arm 122 into a position against their abdomen.
Next, the hip-thrust exercise is performed as shown in FIG. 13, with the user straightening their legs to simultaneously lift padded arm 122, tilt back support 114 backwards, and tilts foot pad 118 forwards as the user thrusts their hips forward. A cable mount 148 is positioned on the bottom back of back support 114 for cable attachment to a weight stack. As such, this hip-thrust exercise can be used to lift a stack of weights.
Back support 114 is connected to seat and foot support 116 by an elongated member 130, wherein a first end 131 of elongated member 130 is connected to the back support and a second end 132 of elongated member 130 is connected to the seat and foot support 116. As can be seen, the seat and foot support 116 (which comprises a seat 117 and a foot pad 118) pivots together as a single unit.
In optional preferred embodiments, abdomen restraint 120 comprises a moveable member 121. The user can adjust the position of the padded arm 122 by moving member 121 to a preferred position using positional adjuster 140.
In an exemplary embodiment of positional adjuster 140 seen in FIGS. 15 to 16B, positional adjuster 140 comprises member 121 connected to back support 114 by a pair of parallel members 150 and 152. A pin (not shown) can be inserted through any of the apertures in selection aperture panel 155 to lock the position of arms 150 and 152. A travel limit pin 157 is free to move within the constraints of the side groove of selection aperture panel 155. (Specifically, as seen in FIG. 15, pin 157 is at the lowermost position when padded arm 122 is positioned against the user's abdomen. Conversely, as seen in FIGS. 16A and 16B, pin 157 is at the uppermost position when padded arm 122 is positioned farthest away from the user's abdomen.)
FIG. 17 shows another embodiment of positional adjuster 140 (in which moveable member 121 telescopes over stationary member 123). Specifically, adjuster 140 can be used to lock and unlock a pin 141 in the telescoping member 121 (which is received over stationary member 123). Adjuster 140 can comprise a rocker arm 142, as shown. The user simply pulls back on rocker arm 142 to unlock pin 141 (permitting telescoping member 121 to be moved with respect to stationary member 123). When the preferred position of padded arm 122 is reached, rocker arm 142 can then be pushed forward to lock pin 141 through the holes in members 121 and 123, thereby locking padded arm 122 across the user's abdomen.
In an alternate exemplary embodiment of the positional adjuster, as seen in FIG. 18, adjuster 140 comprises a latch 145 at the distal end of telescoping member 121. Latch 145 moves member 148 which in turn locks/unlocks pin 141, as shown.
In yet another embodiment of the hip-thrust exercise machine 200 as seen in FIGS. 19 to 21, the user adopts a more reclining position prior to starting the hip-thrust exercise (FIG. 19). As can be seen, back support 214 supports the user's hips as well (and there is no need for a seat 117 as seen in FIG. 12). During the exercise, the user first moves padded arm 222 into a position against their abdomen. Next, the hip-thrust exercise is performed as shown in FIG. 20, with the user straightening their legs to simultaneously lift padded arm 222, tilt back support 214 backwards, and tilt foot pad 218 forwards (i.e.: push foot pad 218 downwardly) as the user thrusts their hips forward. In this particular embodiment, support 216 is not connected to a seat (e.g.: 117 in FIG. 12). Instead, support 216 is connected to a pivot member 219 which is connected to back support 214, as shown. FIG. 21 shows a rear perspective view of device 200.
FIGS. 22 to 24B show yet another embodiment of device 300. In the device of FIGS. 22 and 23, the seat 317 remains stationary and does not move together with support 316. In addition, the hinge point directly under the foot has been replaced with a short link. Also, foot pad 318 is free to move back and forth slightly such that the user's lower leg moves back as the user's torso rocks back during the exercise. Lastly, as seen in FIGS. 24A and 24B, at least two different systems for moving foot mount 318 back and forth can be provided. Specifically, as seen in FIG. 24A, such systems can include a linear bearing with a pivot mount 320. Alternatively, as seen in FIG. 24B, such systems can include a roller and mating rail 340. Alternative systems may be used instead, all keeping within the scope of the present system. In addition, the footpad 318 can optionally slide with respect to support 316. In embodiments where the footpad 318 does not slide with respect to support 316, the footpad and system links act as a counter weight that automatically returns the machine to the starting point at the end of each exercise repetition. This is advantageous when light weights are selected as it eliminates the need for a discreet counterweight in the back pad assembly.
FIGS. 25A to 25D show yet another embodiment of device 400. As can be seen, machine 400 comprises a stationary frame 412; a moveable support 420 connected to stationary frame 412; a rotatable back support 414 connected to moveable support 420; and an abdomen restraint 432 connected both to stationary frame 412 and moveable support 420.
FIG. 25C shows exercise machine 400 in an at rest position between exercises, and FIG. 25D shows exercise machine 400 in a fully extended position during a glute press exercise. FIG. 25B also shows the device in a fully extended position during a glute press exercise. In operation, the user pushes the abdomen restraint 432 (by pushing up on padded arm 422 while tilting the back support 414 backwards when the user thrusts their hips forward.
A seat 417 is connected to moveable support 420, and the seat 417 tilts forwards when the user thrusts their hips forward. Specifically, seat 417 rotates downwardly away from the user's hips during a glute press exercise and rotates upwardly again to contact the user's bottom between exercise repetitions.
As can be seen, a bottom end of moveable support 20 can be rotatably connected to stationary frame 412 and a top end of moveable support 20 can be rotatably connected to rotatable back support 414. Additionally, a support member 432 can be provided to connect abdomen restraint 432 to stationary frame 412. In operation, the stationary frame 412, moveable support 420, abdomen restraint 432 and support member 434 together form a four-bar linkage. As a result, as is seen by comparing FIGS. 25C to 25D, the rotatable back support 414 rotates about an axis 450 that moves with respect to stationary frame 412 during an exercise. As seen in FIG. 25D, axis 450 moves forwards as the rotatable back support is tilted backwards during a glute press exercise. Conversely, axis 450 moves backwards as the rotatable back support is tilted forwards after completing a glute press exercise. Axis 450 moves forwards and back and somewhat up and down, but preferably does not pass through stationary frame 412.
Similar to the other above-described embodiments, exercise machine 400 includes a foot support 418 connected to stationary frame 412. Also, rotatable back support 414 preferably has an upper and a lower portion, and the lower portion extends below the user's hips to support the user's hips during a glute press exercise. The lower portion of rotatable back support 414 preferably supports at least 10% of the user's weight and is angled under the user's hips to support the user's hips. The user's total body weight is not solely supported by the user's upper back and feet. Additionally, a free weight or weights 460 can be attached to abdomen restraint 432 as seen in FIG. 25B. Alternatively, a weight stack and cable can be included in this embodiment as well with the cable connecting the rotatable back support to the weight stack assembly such that rotation of the rotatable back support 414 lifts one or more weights in the weight stack assembly.
FIG. 26A to FIG. 27B show side perspective views of alternate embodiments of the moveable support under the rotatable back support, as follows. First, in FIGS. 26A and 26B, a moveable support 520 is positioned under rotatable back support 514. Moveable support 520 includes bars 522, 524 and 526. Bars 522 and 524 are connected at their upper ends to support 523, and at their lower ends to stationary frame 512. In this embodiment, the weight may be loaded onto the front (i.e.: lower) end of the rotatable back support 514 as shown. This has the optional advantage of putting the weight plates on rotatable back support itself (rather than on a separate arm as seen in other embodiments). At the start of the exercise, bars 522 and 524 are angled as shown. At the end of the exercise, bars 522 and 524 rotate to reach a near vertical orientation.
Next, FIGS. 27A and 27B shows a moveable support 540 that is positioned under rotatable back support 514. (Various elements of the system have been removed for clarity of illustration). Moveable support comprises bars 542 and 544. Bar 542 is connected to linear carriage 546 which moves back and forth in a horizontal direction as the user performs the exercise. Both of the embodiments of FIGS. 26A to 27B have the advantage of the feel of the exercise not being too light at the end of the exercise.
