Anti-tipping apparatus for walkers
View Patent ↗Systems and methods are disclosed for preventing tipping of a walking aid including a sensor configured to detect an angle of tilt in a forward direction of a walking aid, an actuator configured to determine whether the angle of tilt crosses a pre-set threshold, and a retractable support that prevents tipping of the walking aid, wherein the actuator causes the retractable support to extend from the walking aid in the forward direction to limit the tilt of the walking aid when the actuator determines that the angle of tilt crosses the pre-set threshold.
1. An apparatus comprising:
a sensor configured to detect an angle of tilt in a forward direction of a walking aid;
an actuator configured to determine whether the angle of tilt crosses a pre-set threshold; and
a retractable support configured to prevent a tipping of the walking aid,
wherein the actuator causes the retractable support to extend from the walking aid in the forward direction to limit the angle of tilt of the walking aid when the actuator determines that the angle of tilt crosses the pre-set threshold.
2. The apparatus of claim 1 , wherein the forward direction is measured in a horizontal plane along an axis aligned with a direction that a user of the walking aid is walking.
3. The apparatus of claim 1 , wherein the sensor is an electronic sensor.
4. The apparatus of claim 3 , wherein the electronic sensor comprises at least one of an accelerometer, a tilt sensor, or a gyroscope.
5. The apparatus of claim 1 , wherein the pre-set threshold is 80 degrees relative to a horizontal plane.
6. The apparatus of claim 1 , wherein the actuator comprises at least one of a mechanical actuator, a pneumatic actuator, or an electronic actuator.
7. The apparatus of claim 1 , wherein the retractable support comprises at least two legs.
8. The apparatus of claim 7 , wherein the at least two legs are rotatably coupled to a frame of the walking aid to permit the at least two legs to pivot with respect to the frame of the walking aid.
9. The apparatus of claim 1 , further comprising a retractor configured to retract the retractable support.
10. The apparatus of claim 1 , further comprising an alarm configured to indicate that a user of the walking aid requires assistance.
11. The apparatus of claim 10 , wherein the alarm produces at least one of an auditory signal or a visual signal.
12. The apparatus of claim 1 , wherein the walking aid is a walker or a cane.
13. A method configured to prevent a tipping of a walking aid, the method comprising:
detecting with a sensor an angle of tilt of the walking aid in a forward direction;
determining with an actuator whether the angle of tilt crosses a pre-set threshold; and
automatically extending a retractable support in the forward direction upon determining that the angle of tilt crosses the pre-set threshold.
14. The method of claim 13 , wherein the forward direction is measured in a horizontal plane along an axis aligned with a direction that a user of the walking aid is walking.
15. The method of claim 14 , wherein the pre-set threshold is 80 degrees relative to the horizontal plane.
16. The method of claim 13 , wherein the retractable support comprises at least two legs.
17. The method of claim 16 , wherein automatically extending the retractable support comprises causing the at least two legs to pivot with respect to a frame of the walking aid.
18. The method of claim 17 , wherein automatically extending the retractable support prevents a user of the walking aid from falling forward while using the walking aid.
19. The method of claim 18 , further comprising retracting the retractable support after the retractable support is released.
20. The method of claim 13 , further comprising indicating that a user of the walking aid requires assistance.
21. The method of claim 20 , wherein indicating that the user of the walking aid requires assistance comprises producing at least one of an auditory signal or a visual signal.
22. The method of claim 13 , wherein the walking aid is a walker or a cane.
