Abstract

In accordance with various embodiments, a walker has a body. An illumination source is supported by the body. The illumination source is configured to focus illumination on a target area. The target area includes both a leg of a user and ground adjacent the leg during an entire gait cycle of the user using the walker for assistance during ambulation.

Claims

1. An apparatus comprising:

a walker having a body; and

an illumination source supported by the body, the illumination source is configured to focus illumination on a target area, wherein the target area includes both a leg of a user and ground adjacent the leg during an entire gait cycle of the user using the walker for assistance during ambulation, in which the leg is one of two legs of the user, and the target area includes the two legs of the user and the ground adjacent the two legs during the entire gait cycle of the user.

2. The apparatus of claim 1, in which the body of the walker comprises four legs.

3. The apparatus of claim 1, in which the illumination source is a plurality of light sources, wherein each of the plurality of light sources emit light.

4. The apparatus of claim 1, in which the illumination source comprises a first light source configured to emit a first light and an opposing second light source configured to emit a second light.

5. The apparatus of claim 1, in which the illumination source is configured to transition between an ON state and an OFF state responsive to a tap from the leg.

6. The apparatus of claim 1, further comprising:

a sensor supported by the body; and

a light source supported by the body, wherein the light source transitions from an OFF state to an ON state responsive to activation of the sensor.

7. The apparatus of claim 1, further comprising a light source that projects in a general forward direction away from the walker to help the user move.

8. An apparatus comprising:

a body of a walker; and

an illumination source supported by the body, the illumination source is configured to focus illumination on a target area, wherein the target area includes two legs of a user and ground adjacent to the two legs during an entire gait cycle of the user.

9. The apparatus of claim 8, further comprising a light source supported by the body, wherein the light source projects light in a general forward direction away from the walker along a pathway walked by the user during the entire gait cycle.

10. The apparatus of claim 8, in which the target area is illuminated by a pair of opposing light sources that focus light on the target area.

11. The apparatus of claim 8, in which the target area includes an area where the user stands and moves forward while using the walker.

12. The apparatus of claim 8, in which the target area is configured to move forward when the user moves the walker forward during the entire gait cycle.

13. The apparatus of claim 8, in which the illumination source transitions between an ON state and an OFF state responsive to the user tapping the illumination source with at least one of the two legs.

14. The apparatus of claim 8, in which the body provides a left handle and a right handle to support a left hand and a right hand of the user, respectively.

15. The apparatus of claim 14, in which the illumination source is a plurality of light sources that project light on the target area.

16. A walker comprising:

a left side support;

a left illumination source supported by the left side support;

a right side support;

a right illumination source supported by the right side support;

a front support; and

a pathway light supported by the front support, the left illumination source and the right illumination source are configured to focus illumination on a target area, wherein the target area includes two legs of a user and ground adjacent the two legs during an entire gait cycle of the user using the walker for assistance during ambulation, and the pathway light projects in a general forward direction away from the walker in a general direction that the user moves during the entire gait cycle.

17. The walker of claim 16, in which the walker comprises four legs.

18. The walker of claim 16, in which at least one of the left illumination source and the right illumination source are configured to transition between an on ON state and an OFF state responsive to a tap from one of the two legs.

19. The walker of claim 16, in which the target area includes an area where the user stands and moves forward while using the walker.
