Abstract

A walker seat may include a seat bottom and a support structure. The seat bottom may include an anterior region, a posterior region, an upper side, and a lower side. The lower side may include a central segment retention portion. The support structure may include a central segment, a left-side segment, and a right-side segment. The central segment may be retained by the central segment retention portion. The left-side segment may be extendable from a left side of the central segment, whereby the left-side segment extends beyond a left side of the seat bottom. Similarly, the right-side segment may be extendable from a right side of the central segment, whereby the right-side segment extends beyond a right side of the seat bottom.

Claims (39)

1. An apparatus comprising:

a left-side portion including a front leg, a rear leg, and a lateral portion extending between the front leg and the rear leg;

a right-side portion including a front leg, a rear leg, and a lateral portion extending between the front leg and the rear leg;

a front portion mechanically coupled with the left-side portion and the right-side portion, wherein:

the left-side portion is configured to rotate with respect to the front portion; and

the right-side portion is configured to rotate with respect to the front portion;

a seat bottom;

a mounting portion configured to mount the seat bottom to the front portion, wherein the seat bottom is configured to rotate at least 180 degrees about the mounting portion; and

a support structure connected to the seat bottom, wherein the support structure includes:

a left-side segment configured to rest on the lateral portion of the left-side portion; and

a right-side segment configured to rest on the lateral portion of the right-side portion.

2. The apparatus of claim 1 , wherein the mounting portion is releasably attachable to the front portion.

3. The apparatus of claim 2 , wherein the mounting portion comprises at least one clamp configured to clamp onto the front portion.

4. The apparatus of claim 3 , wherein the mounting portion further comprises at least one adjustment knob corresponding to each of the at least one clamp, wherein the at least one adjustment knob is configured to tighten the corresponding clamp to the front portion.

5. The apparatus of claim 1 , wherein the front portion further comprises:

a left-side hollow region configured to accept the left-side portion; and

a right-side hollow region configured to accept the right-side portion.

6. The apparatus of claim 5 , wherein:

the left-side portion is configured to rotate about a primary axis of the left-side hollow region; and

the right-side portion is configured to rotate about a primary axis of the right-side hollow region.

7. The apparatus of claim 1 , further comprising:

a left-side releasably lockable portion extending between the front portion and the left-side portion; and

a right-side releasably lockable portion extending between the front portion and the right-side portion.

8. The apparatus of claim 1 , wherein when the left-side segment of the support structure rests on the lateral portion of the left-side portion and when the right-side segment of the support structure rests on the lateral portion of the right-side portion, the mounting portion is attached to the front portion at an elevation above the seat bottom.

9. The apparatus of claim 1 , wherein the seat bottom comprises an aperture in an anterior region of the seat, wherein the aperture is sized to accept a user's hand.

10. The apparatus of claim 1 , wherein the mounting portion is releasably attachable to the front portion.

11. The apparatus of claim 10 , wherein the mounting portion comprises at least one clamp configured to clamp onto the front portion.

12. The apparatus of claim 11 , wherein the mounting portion further comprises at least one adjustment knob corresponding to each of the at least one clamp, wherein the at least one adjustment knob is configured to tighten the corresponding clamp to the front portion.

13. The apparatus of claim 1 , wherein:

the left-side segment is extendible beyond a left side of the seat bottom; and

the right-side segment is extendible beyond a right side of the seat bottom.

14. The apparatus of claim 13 , further comprising a central segment, wherein:

the left-side segment is removably engageable with the central segment; and

the right-side segment is removably engageable with the central segment.

15. The apparatus of claim 14 , further comprising a spring attached to the left-side segment and the right-side segment.

16. The apparatus of claim 15 , wherein the spring extends through the central segment.

17. The apparatus of claim 13 , wherein:

the left-side segment is telescopically extendible away from the seat bottom; and

the right-side segment is telescopically extendible away from the seat bottom.
