METHOD AND APPARATUS FOR AN EXERCISE MACHINE

INTRODUCTION

Low back and neck pain is an increasingly widespread and expensive condition worldwide, costing the US $88 billion a year. Among adults, 60% to 80% will experience back pain and up to 70% to 75% of people will experience neck pain that interferes with their daily activities during their lifetimes. At any given time, 15% to 20% of adults will report having back pain symptoms. lower back is the second most common reason why an individual will see a doctor. One of the primary reasons for lower back pain is weak core muscles. Having an effective home exercise device that may simultaneously isolate all core muscles in one exercise motion may help strengthen the muscles that contribute to lower back pain and thus reduce chronic lower back pain.

Neck pain affects 30% to 50% of adults in the general population in any given year. Approximately 50%-85% of individuals with neck pain do not experience complete resolution of symptoms. There is a need for an effective home exercise device that may isolate and strengthen neck muscles that contribute to neck pain and thus reduce chronic neck pain.

Horizontal pivot arm 2 rotates around a pivot to allow movement along the z-axis.

Foam pad/cover 3 for the horizontal pivot arm 2 provides cushion against the pressure exerted by the horizontal pivot arm.

Rotation axle 4 provides an attachment point for the horizontal pivot arm 2 to attach to the mechanical load system 1. It also allows the horizontal pivot arm 2 to be adjusted up and down along the y-axis through the use of an attachment pin, which is used to secure the horizontal pivot arm 2 to the rotation axle 4.

The first vertical post 5 is formed by a base adjustment tube 8 and a second adjustment tube 6, which have a telescopic arrangement in one embodiment.

The base adjustment tube 8 and the second adjustment tube 6 facilitate up/down adjustment of the first vertical post 5 in the y-axis so that the mechanical load system 1 may be fitted to users based upon their heights. In one embodiment, it may be adjusted by at least 12 inches (30 cm), which allows adjustment to the first in-use position 2L (illustrated with reference to FIGS. 3 and 4) and the second in-use position 2C (illustrated with reference to FIGS. 7 and 8), thus facilitating exercises used to strengthen the lumbar muscles (L) and the cervical neck muscles (C). The tube is held in position in the y-axis through the use of an attachment pin 7. Attachment pin 7 is employed to secure the adjustment tube 6 to base adjustment tube 8.

The base adjustment tube 8 is attached to horizontal base 10.

The horizontal base 10 includes rear base tube 11, central base tube 12, and front base tube 13.

Transportation wheels 9 include a pair of wheels or casters that are attached to the rear base tube 11 to allow the physical exercise machine 100 to be tilted and easily moved. Alternatively, multiple wheels, rollers, casters, sliders, may be employed, without limitation.

In one embodiment and as shown, controller 19 is a tablet.

The controller 19 is linked to the mechanical load system 1 which may include, in one embodiment, a sensor (through the use of a wired connection, an infrared connection, a radio frequency connection, a Bluetooth connection, cellular connection or a WiFi connection) and used to control a position, resistance or other parameter of the controllable resistance device. It may also be used to monitor and capture usage information, such as frequency of use, duration of use, history of use, range of motion information, resistance levels and range of motion or strength improvement over time. Further, some embodiments, such as those not using electromechanical resistance, may use this as an electronic computerized instructional device or application linked to the device to set up training routines or regimens for the user. A controller adjustment collar attaches to the pivotable post 25. A controller bracket is employed when attaching a tablet or electronic interface device to the front of the device, it is used to attach the tablet or electronic interface device and position it so that the tablet or electronic interface device does not prevent exercise.

A kneepad assembly 24 is used to lock the user's knees into place, it may be adjusted up and down (move along the y-axis) to accommodate different size users. It may be locked in place using the attachment pin 23. Kneepads 22 are used to cushion the user's knees. They cover the bar portion of the kneepad assembly 24. An attachment pin is used to secure the kneepad assembly 24 into place on the pivotable post 25.

A pivotable post 25 is used to lock the user's knees into place employing the kneepad assembly 24. The pivotable post 25 may be pivoted in towards or away from the user (z-axis) to allow the kneepad assembly 24 to be locked into position. In the present configuration it is angled so that the angle at the rear of the pivotable post 25 forms an acute angle with the central base tube 12. However, other configurations may form ninety-degree angles or obtuse angles.

Pivot bar retaining body 26 is used to lock the pivotable post into place with a locking pin 39. It is permanently attached to the central base tube 12.

Attachment pin 27 is used to secure the footplate adjustment bracket 3e to the pivotable post 25.

Pivot bar hinge pin 28 allows the pivotable post 25 to pivot forward and backward (in the z-axis). The pivot bar hinge pin 28 connects the pivotable post 25 with the central base tube 12.

Attachment pin 29 is used to secure the central base tube extension 31 to the central base tube 12.

Pivot 30 allows the pivotable post 25 to rotate within the pivotable post pivot base 32.

Central base tube extension 31 is used to allow the pivotable post 25 and the attached footplates 34 and kneepad assembly 24 to be adjusted away from or closer to the user (along the z-axis).

Pivotable post pivot base 32 allows the pivot 30 to rotate within the pivotable post pivot base 32, which allows the limited rotation of the pivotable post 25 in relation to the central base tube extension 31 and central base tube 12.

Footplate adjustment bracket 33 attaches to the pivotable post 25 with the attachment pin 27 to allow the footplate adjustment bracket 33 to be moved up or down (along the y-axis) to accommodate different size users.

The footplate 34 is used to support the user's feet while using the device. It attaches to the footplate adjustment bracket 33.

Attachment pin 35 may be used to secure the piston 37 to the piston attachment bracket 36.

Piston attachment bracket 36 attaches to piston adjustment tube (upper) 56 and serves as the attachment point for the lower end of the piston 37.

Piston 37 is a pre-charged pneumatic or hydraulic cylinder that may be charged to various pressure levels to provide different resistance values. This provides the resistance force for this embodiment of the piston version of the device. One end of the piston 37 is secured to an eccentric connection point 38 of the rotation retaining plate 39 via an attachment pin. Different connection points may be spaced along the base adjustment tube 8 to accommodate adjustment of the adjustment tube 6.

Rotation retaining plate 39 serves as the connection point for the piston 37 and the rotation retaining plate 39 rotates around the horizontal pivot arm pivot bearing 54. This rotation allows the horizontal pivot arm 2 to rotate as the resistance housing rotation axle 4 rotates around the horizontal pivot arm pivot bearing 54. When disengaged with a rotation release locking pin (not shown), it will allow the horizontal pivot arm 2 to rotate freely. When engaged with the rotation release locking pin, it will allow the horizontal pivot arm 2 to rotate or under load (resistance). It is also where the rotation stop-pin 55 is engaged to stop the rotation of the horizontal pivot arm 2 at a predetermined interval, which is associated with a range of motion (ROM).

Horizontal pivot arm pivot mount 40 is attached to the second adjustment tube 6, providing an attachment point for the horizontal pivot arm pivot bearing 54, about which the rotation retaining plate 39, the horizontal pivot arm 2 and the resistance housing rotation axle 4 all rotate.

Rotation release handle 41 is used to release the horizontal pivot arm 2, permitting it to pivot in towards the user (z-axis) for setting the in-use position, pivot out to an entrance position from the user (z-axis) to permit user ingress and egress. Rotating the rotation release handle 41 half a turn rotates a rotation release cam that allows a rotation release pin to push against a rotation release locking pin (not shown). This pulls the rotation release locking pin out of the hole that allows it to lock to the rotation retaining plate 39. This also compresses a rotation release spring, which pushes the rotation release locking pin back into a locked position when the force is released, i.e., the rotation release handle 41 is rotated back to the starting position.

Rotation release handle grip cover 42 is a device fabricated from foam or similar material used to allow the rotation release handle 41 to be more easily gripped.

Rotation release cam is a cam mechanism that is permanently attached to and rotates as the rotation release handle 41 is rotated. This rotation translates the rotation of the rotation release handle 41 into a side-to-side motion (along the x-axis) of the rotation release locking pin which allows it to engage or disengage with the rotation retaining plate 39 to either lock or release the pivotable post 25.

Rotation release pin is attached to the rotation release locking pin and rides inside the groove on the rotation release cam to translate the rotation of the rotation release handle 41 into a side-to-side motion (along the x-axis) of the rotation release locking pin. This allows it to engage or disengage with the rotation retaining plate 39 to either lock or release the horizontal pivot arm 2. The rotation release locking pin engages with the rotation retaining plate 39 to either lock or release the horizontal pivot arm 2. The rotation release spring surrounds the rotation release locking pin. As the rotation release cam translates the rotation of the rotation release handle 41 into movement of the rotation release locking pin the rotation release spring is compressed to provide stored energy to force the release locking pin back into a hole on the rotation retaining plate 39 to lock the horizontal pivot arm 2 into place.

Pivotable post release handle 47 is used to release the pivotable post 25, so that it may pivot in towards or away from the user (z-axis) to allow the kneepad assembly 24 to be locked into position. Rotating the pivotable post release handle 47 half a turn rotates a cam that allows a pivotable post release pin to push against a pivotable post release locking pin. This pulls the pivotable post release locking pin out of the hole that allows it to lock to the pivotable post retaining body 26. This also compresses a pivotable post release spring, which pushes the pivotable post release locking pin back into a locked position when the force is released, i.e., the pivotable post release handle 47 is rotated back to the starting position. Pivotable post release handle grip cover 48 is a device fabricated from foam or similar material used to allow the pivotable post release handle 47 to be more easily gripped.

Pivotable post release cam is a cam mechanism that is permanently attached to and rotates as the pivotable post release handle 47 is rotated. This rotation translates the rotation of the pivotable post release handle 47 into a side-to-side motion (along the x-axis) of the pivotable post release locking pin which allows it to engage or disengage with the pivotable post retaining body 26 to either lock or release the pivotable post 25.

Pivotable post release pin is attached to the pivotable post release locking pin and rides inside the groove on the pivotable post release cam to translate the rotation of the pivotable post release handle 47 into a side-to-side motion (along the x-axis) of the rotation release locking pin. This allows it to engage or disengage with the rotation retaining plate 39 to either lock or release the horizontal pivot arm 2.

The pivotable post release locking pin engages with the pivotable post retaining body 26 to either lock or release the pivotable post 25.

The pivotable post release spring surrounds the pivotable post release locking pin. As the pivotable post release cam translates the rotation of the pivotable post release handle 47 into movement of the pivotable post release locking pin, the pivotable post release spring is compressed to provide stored energy to force the pivotable post release locking pin back into a hole on the pivotable post retaining body 26 to lock the pivotable post 25 into place.

Wheel attachment bracket 53 connects the transportation wheels 9 to the rear base tube 11, allowing the device to be easily transported.

Horizontal pivot arm pivot bearing 54 provides a pivot point which allows the pivotable post 2 and resistance housing rotation axle 4 to rotate.

Rotation stop-pin 55 connects to the rotation retaining plate 39 and is used to stop the rotation of the pivotable post 25 (at a predetermined point) by contacting the Horizontal pivot arm pivot mount 40. In one embodiment, the rotation stop-pin connects to the mechanical load system 1 and is used to stop the rotation of the resistance housing rotation axle 4 and the horizontal pivot arm 2 (at a predetermined point) by coming into contact with the rotation stop arm 63.

Piston adjustment tube (upper) 56 is employed to mount the piston attachment bracket 36 to allow the stroke of the piston to be adjusted up and down along the y-axis.

Piston adjustment tube (lower) 57 is mounted to the base adjustment tube 8. It holds the Piston Adjustment tube (upper) 56, which allows the stroke of the piston to be adjusted up and down along the y-axis by cranking the Piston adjustment handle 58. If the device is configured for working the neck (cervical) muscles, then this element may have an alternate mounting position higher up (in the y-axis) on the electromechanical resistance housing base adjustment tube 8.

Piston adjustment handle 58 is used to adjust the stroke of the piston up and down along the y-axis. Turning the handle actuates an internal mechanism that moves the piston adjustment tube (lower) 57 up and down, within the piston adjustment tube (upper) 56. The crank mechanism may take on a number of different configurations using beveled gears, ring and screen gears, pinion and rack gears or other configurations.

Cord hanger 59 includes an upper and lower loop and is used to stow/wrap the electrical cord 61 for transportation or storage, when employed. Electrical cord 61 is used to provide power to the mechanical load system 1 in some embodiments.

Emergency stop switch 62 is used to immediately cease energization of the resistance producing mechanism in a version of the device that does not use pistons. This mechanism is housed in the mechanical load system 1. This is connected to the electrical cord 61 directly, externally, or via internal wiring (not shown) routed through the tubing, second adjustment tube 6 and the base adjustment tube 8.

Rotation stop arm 63 is attached to the resistance housing rotation axle 4. It stops the rotation of the resistance housing rotation axle 4 and the Horizontal pivot arm 2 (at a predetermined point) by preventing the resistance housing rotation axle 4 and the horizontal pivot arm 2 from rotating when the rotation stop arm 63 comes into contact with the rotation stop-pin 55.

Pivot 30 rotates around a pivot point at pivotable post hinge pin 28, to allow the kneepads 22 and kneepad assembly 24 to secure the knees in front of or above the knees. A modification in the design may allow the pads to secure the knees simultaneously above and in front of the knee. Similarly, an additional pad may be added to allow popliteal support behind the knees.

Pivotable post release handle 47 is used to disengage the rotation release locking pin, which slides into holes on the pivotable post retaining body 26 to lock the pivotable post 25 into an in-use position. This may be accomplished via a cable release like a bike brake handle, or a spring-loaded pin similar to a button handle locking pin or a mechanism. In one embodiment, and as shown, a cammed, twist handle is employed to release the pin. Disengaging the locking mechanism will allow the pivotable post 25 to be tilted into position to lock the user's knees into place in-use or to move away from the patient's knees after an exercise routine is complete. Re-engaging the pivotable post release handle 47 locks the pivotable post 25 into position for exercising, in the in-use position. At the end of exercise, the pivotable post release handle 47 may be used to release the pivoting member so that it may be returned to the rest position.

An embodiment of the user exercise system 20 includes movable horizontal arm 2 coupled to rotation retaining plate 39, and mechanical load system 1. This embodiment of the physical exercise machine 200 is designed to be placed and used on a flat surface, such as a floor area or a tabletop. There is no footplate or kneepad assembly in this embodiment.

The user exercise system 20 is mounted on the first vertical post 5. The user exercise system 20 has a horizontal pivot arm 2 that is coupled to a mechanical load system 1.

The horizontal pivot arm 2 is vertically rotatably coupled to the mechanical load system 1. The horizontal pivot arm 2 is adjustable to one of a first vertical position or a second vertical position relative to the seat 65, wherein the first vertical position is proximal to a lumbar region of a user when disposed on the seat 65, and wherein the second vertical position is proximal to a cervical region of the user when disposed on the seat 65. The mechanical load system 1 is controllable to urge a mechanical resistance in opposition to a force being exerted on the horizontal pivot arm 2, wherein the force being exerted on the horizontal pivot arm 2 may be in the form of a user who is engaged in an exercise routine. The horizontal pivot arm 2 of the user exercise system 20 is also rotatable in a horizontal plane to either an in-use position (as shown) or a rest position. This ability to rotate the horizontal pivot arm 2 in the horizontal plane facilitates user ingress/egress to the seat 65 prior to beginning an exercise routine and after completing an exercise routine.

The horizontal base extension 66 is extendable from the frame 64 behind the seat 65. The rotation retaining plate 39 is rotatably coupled to the single vertical post 67. In one embodiment, the mechanical load system 1 includes a piston 37 that extends between a distal end of the horizontal base extension 66 and an off-center or eccentric connection point 38 on the rotation retaining plate 39. One end of the piston 37 is secured to the rotation retaining plate 39 at eccentric connection point 38 via an attachment pin. The mechanical load system 1 is arranged to exert a mechanical resistance to a force being exerted on the horizontal pivot arm 2.

The frame 64 is divided into first and second frame portions 64A and 64B, respectively, which are joined at hinge 81. Frame 64 supports the seat cushions 65 and provides the base on which the horizontal base extension 66, the vertical post 67, back support base extension 69 and the wheel attachment brackets 53 are attached. Seat cushion 65 is a cushioned pad or upholstered seat that attaches to the back support base adjustment bracket 70 and provides a place for the user to sit. Seat cushion 65 is divided into first and second portions 65A and 65B, respectively, which correspond to the first and second frame portions 64A and 64B, respectively. The first frame portion 64A and the first seat portion 65A are coplanar with the second frame portion 64B and the second seat portion 65B when the exercise machine 200 is arranged in an in-use state. This is depicted with reference to FIGS. 9 and 10.
