Abstract

An electromagnetic anti-tipping device uses electromagnets to steady users and prevent falls by persons with impaired mobility and balance. The device'"'"'s steadying effect is accomplished by magnetically attracting the legs and/or wheels of balance and mobility assisting apparatus (“balance and mobility aid(s)”) to a stationary surface such as a floor which is made of or covered with a magnetically responsive material. In one embodiment, the device'"'"'s electromagnet attraction to the floor or other stationary surface is actuated when the operator of the device triggers the device'"'"'s mechanism or sensor by grip or touch. Once actuated, and until deactivation by the user, the device'"'"'s electromagnet(s) secure the legs or wheels of the balance and mobility aid to the magnetically responsive floor or other stationary surface. The electromagnets are battery-powered.

Claims

1. An anti-tipping mechanism comprising:

a. a mobility aid having a frame;

b. electromagnets temporarily securing and balancing the mobility aid, wherein the electromagnets are attached to the frame of the mobility aid, wherein the electromagnets secure and balance the frame when activated by attracting to a floor that the mobility aid is moving upon, wherein the electromagnets are secured to the frame at a lower portion of the frame, wherein the electromagnets are attracted to the floor when the electromagnets are activated so that the frame is secured to the floor.

2. The anti-tipping mechanism of claim 1, wherein the mobility aid remains in contact with the magnetic surface when the mobility aid is lifted slightly off the magnetic surface.

3. The anti-tipping mechanism of claim 1, further including controls for allowing direct or indirect operation by the operator of the balance and mobility aid device, wherein the controls activate the mobility aid.

4. The anti-tipping mechanism of claim 1, wherein the mobility aid is a mobility aid means.

5. The anti-tipping mechanism of claim 1, further comprising a magnetic surface for attracting to the electromagnet by electromagnetic attraction.

6. An anti-tipping mechanism for use on a floor comprising:

a. a mobility aid having a frame;

b. electromagnets mounted to the frame, wherein the electromagnets secure and balance the frame when activated by attracting to the floor that the mobility aid is moving upon, wherein the electromagnets are secured to the frame at a lower portion of the frame;

c. a battery that is electrically connected to the electromagnets for activating the electromagnets;

d. a control having a first mode, and a second mode, wherein the first mode deactivates the electromagnets, and wherein the second mode activates the electromagnets when a tipping sensor is triggered.

7. The anti-tipping mechanism of claim 6, further comprising a spring that provides a suspension to the electromagnet, wherein the electromagnet contacts with the floor when a portion of the mobility aid is lifted above the floor.

8. The anti-tipping mechanism of claim 6, wherein the control further includes a third mode, wherein the third mode selectively activates the electromagnets.

9. The anti-tipping mechanism of claim 8, further comprising a tipping sensor configured to sense tipping of the mobility aid, wherein the electromagnet is configured to activate when the tipping sensor senses tipping of the mobility aid, wherein the tipping sensor includes a pressure sensor.

10. The anti-tipping mechanism of claim 8, further comprising a pair of wheels connected to the lower portion of the frame, wherein the wheels provide a rolling movement for the user.

11. The anti-tipping mechanism of claim 8, wherein the mobility aid is a walker.

12. The anti-tipping mechanism of claim 8, further comprising a tipping sensor configured to sense tipping of the mobility aid, wherein the electromagnet is configured to activate when the tipping sensor senses tipping of the mobility aid;

and

further comprising a pair of wheels connected to the lower portion of the frame, wherein the wheels provide a rolling movement for the user; and

further comprising a spring that provides a suspension to the electromagnet;

wherein the electromagnet contacts with the floor when a portion of the mobility aid is lifted above the floor.

13. The anti-tipping mechanism of claim 12, wherein the mobility aid is a walker.

14. The anti-tipping mechanism of claim 12, wherein the tipping sensor also includes a two axis accelerometer and a two axis tilt sensor that work in conjunction with the pressure sensor.
