Abstract

A leg stretching device includes a base frame, a support plate adjustably coupled to the base frame, a leg tube including a proximal end hingedly connected to the base frame and a distal end, a foot plate disposed at the distal end of the leg tube, and an actuation assembly including an actuation tube hingedly connected to the base frame and an actuation bar slidably disposed within the actuation tube and hingedly connected to the leg tube. The actuation assembly includes an actuator motor for moving the actuation bar relative to the actuation tube to reposition the leg tube relative to the base frame.

Claims (30)

1. A leg stretching device comprising:

a linear base frame configured to extend along a lateral side of a user in a supine position;

a support plate adjustably coupled to, and extending laterally from, the base frame, the support plate configured for positioning against a back side of the user;

a lower lumbar pad adjustably coupled to, and extending laterally from, the base frame in spaced relation relative to the support plate;

a hip pivot axle extending through a hinge cover, the hinge cover adjustably coupled to the base frame;

a leg tube including a proximal end hingedly connected to the base frame about the hip pivot axle and a distal end;

a foot plate operably coupled to the distal end of the leg tube; and

an actuation assembly including an actuation tube hingedly connected to the base frame and an actuation bar slidably disposed within the actuation tube and hingedly connected to the leg tube, the actuation assembly including an actuator motor for moving the actuation bar relative to the actuation tube to reposition the leg tube relative to the base frame.

2. The leg stretching device of claim 1 , further including a thigh foam support roller adjustably coupled to the leg tube.

3. The leg stretching device of claim 1 , further including a foam ankle cuff roller adjustably coupled to the leg tube.

4. The leg stretching device of claim 1 , wherein the hinge cover includes a degree label.

5. The leg stretching device of claim 1 , wherein the leg tube includes an upper leg tube telescopically coupled with a lower leg tube such that an overall length of the leg tube is adjustable.

6. The leg stretching device of claim 1 , further including an electronic controller for controlling the actuator motor of the actuation assembly.

7. The leg stretching device of claim 6 , wherein the electronic controller is a handheld remote control.

8. The leg stretching device of claim 5 , further including a knee support roller disposed around a knee support axle and configured to be positioned against a front of a knee of the user, the knee support axle adjustably coupled to the upper leg tube.

9. The leg stretching device of claim 5 , further including an ankle support roller disposed around a distal portion of the lower leg tube in spaced relation to the foot plate, the ankle support roller configured to be positioned against a back of an ankle of the user.

10. The leg stretching device of claim 5 , wherein the foot plate is supported on a foot support axle, the foot support axle secured to the lower leg tube by at least one foot plate adjustment bracket.

11. The leg stretching device of claim 1 , further including a second foot plate operably coupled to the distal end of the leg tube.

12. The leg stretching device of claim 5 , wherein the upper leg tube is disposed above the base frame and is moveable relative thereto along a vertical plane defined by the base frame.

13. A method of stretching a leg comprising:

resting a back side of a user on a support plate that is adjustably coupled to, and extending laterally from, a linear base frame of a leg stretching device, the base frame extending along a lateral side of the user in a supine position;

resting a lower back of the user against a lower lumbar pad that is adjustably coupled to, and extending laterally from, the base frame in spaced relation relative to the support plate;

aligning a hip of the user with a hip pivot axle of the leg stretching device, the hip pivot axle extending through a hinge cover that is adjustably coupled to the base frame and hingedly connecting the base frame of the leg stretching device to a proximal end of a leg tube of the leg stretching device;

resting a foot of the user against a footplate operably coupled to a distal end of the leg tube of the leg stretching device; and

actuating an actuator motor of the leg stretching device to raise the leg tube and elevate the foot of the user, the actuation assembly including an actuation tube hingedly connected to the base frame and an actuation bar slidably disposed within the actuation tube and hingedly connected to the leg tube, the actuation assembly including an actuation motor for moving the actuation bar relative to the actuation tube to reposition the leg tube relative to the base frame.

14. The method of claim 13 , further including resting a knee of the user against a thigh foam support roller of the leg stretching device, the thigh foam support roller being adjustably coupled to the leg tube of the leg stretching device.

15. The method of claim 13 , further including resting an ankle of the user against a foam ankle cuff roller of the leg stretching device, the foam ankle cuff roller being adjustably coupled to the leg tube of the leg stretching device.

16. The method of claim 13 , further including strapping at least one of a thigh, an ankle, or a foot of the user to the leg stretching device with a retention strap.

17. The method of claim 13 , further including adjusting a position of at least one of the support plate or the footplate prior to actuating the actuator motor.

18. The method of claim 13 , further including measuring a degree of hip flexion at the hip pivot axle.
