Abstract

A wrap around walking aid is configured to assist a human user in walking. The wrap around walking aid comprising has a first rear lower frame and a first front lower frame mechanically coupled to a first upper frame. A back rest is connected to the first rear lower frame. A second rear lower frame and a second front lower frame are mechanically coupled to a second upper frame. The second rear lower frame is further mechanically coupled to the back rest. At least one first fixed front wheel is mechanically coupled to both front lower frames. At least one first castor rear wheel is mechanically coupled to both rear lower frames. The wheels enable a turn radius while the human user is walking forward.

Claims (73)

1. A wrap around walking aid, that assists a human user in walking; the wrap around walking aid comprising:

at least one first castor rear wheel mechanically coupled to the first rear lower frame;

a first telescoping segment, extending from within the first rear lower frame and tightened into place by a first height adjustment; wherein the first telescoping segment is on a first telescoping axis; and

a first forearm support segment joined to the first telescoping segment; wherein the first forearm support segment extends on a first forearm axis; wherein measured from the first telescoping segment, the first forearm support segment is arranged at a first obtuse angle that is greater than 90 degrees;

a first handle segment joined to the first forearm support segment;

a back rest, connected to the first rear lower frame

a second rear lower frame and a second front lower frame mechanically coupled to a second upper frame; wherein the second rear lower frame is further mechanically coupled to the back rest;

at least one second fixed front wheel mechanically coupled to the second front lower frame;

at least one second castor rear wheel mechanically coupled to the second rear lower frame;

wherein the at least one first castor rear wheel, the at least one second castor rear wheel, the at least one first fixed front wheel and the at least one second fixed front wheel enable a turn radius while the human user is walking forward.

2. The wrap around walking aid of claim 1 , further comprising:

a first folding point arranged between the first front lower frame and the first rear lower frame; wherein the first folding point permits the first front lower frame to fold upon the first rear lower frame; and

a second folding point arranged between the second front lower frame and the second rear lower frame; wherein the second folding point permits the second front lower frame to fold upon the second rear lower frame.

3. The wrap around walking aid of claim 2 , further comprising:

at least one first strut connected to the first rear lower frame and the first front lower frame; wherein the at least one first strut limits the first front lower frame moving away from the first rear lower frame; and

at least one second strut connected to the second rear lower frame and the second front lower frame; wherein the at least one second strut limits the second front lower frame moving away from the second rear lower frame.

4. The wrap around walking aid of claim 3 , further comprising:

a seat rest mechanically coupled to the first front lower frame and the second front lower frame; and

a seat pivot attached to a seat and the back rest;

wherein rotating the seat from the seat pivot causes the seat to rest upon the seat rest.

5. The wrap around walking aid of claim 4 , further comprising:

a first handle mechanically coupled to the first handle segment;

a first hand brake mechanically coupled to the first handle; and

a first brake cable connected to the first hand brake and the at least one first fixed front wheel;

wherein squeezing the first hand brake engages the first brake cable to stop motion of the at least one first fixed front wheel.

6. The wrap around walking aid of claim 5 , further comprising: a first forearm rest mechanically coupled to the first forearm support segment.

7. The wrap around walking aid of claim 6 , wherein the second upper frame further comprises:

a second telescoping segment, extends from within the second rear lower frame and is tightened into place by a second height adjustment; wherein the second telescoping segment is on a second telescoping axis;

a second forearm support segment joined to the second telescoping segment; wherein the second forearm support segment extends on a second forearm axis; wherein measured from the second telescoping segment, the second forearm support segment is arranged at a second obtuse angle that is greater than 90 degrees; and

a second handle segment joined to the second forearm support segment.

8. The wrap around walking aid of claim 7 , further comprising:

a second handle mechanically coupled to the second handle segment;

a second hand brake mechanically coupled to the second handle; and

a second brake cable connected to the second hand brake and the at least one second fixed front wheel;

wherein squeezing the second hand brake engages the second brake cable to stop motion of the at least one second fixed front wheel.

9. The wrap around walking aid of claim 8 , further comprising: a second forearm rest mechanically coupled to the second forearm support segment.

10. A wrap around walking aid, which assists a human user in walking; the wrap around walking aid comprising:

a first rear lower frame and a first front lower frame mechanically coupled to a first upper frame;

at least one first fixed front wheel mechanically coupled to the first front lower frame;

at least one first castor rear wheel mechanically coupled to the first rear lower frame;

a first telescoping segment, extending from within the first rear lower frame and tightened into place by a first height adjustment; wherein the first telescoping segment is on a first telescoping axis; and

a first forearm support segment joined to the first telescoping segment; wherein the first forearm support segment extends on a first forearm axis; wherein measured from the first telescoping segment, the first forearm support segment is arranged at a first obtuse angle that is greater than 90 degrees;

a first handle segment joined to the first forearm support segment;

a first folding point arranged between the first front lower frame and the first rear lower frame; wherein the first folding point permits the first front lower frame to fold upon the first rear lower frame;

at least one first strut connected to the first rear lower frame and the first front lower frame; wherein the at least one first strut limits the first front lower frame moving away from the first rear lower frame;

a back rest, connected to the first rear lower frame;

a second rear lower frame and a second front lower frame mechanically coupled to a second upper frame; wherein the second rear lower frame is further mechanically coupled to the back rest;

at least one second fixed front wheel mechanically coupled to the second front lower frame;

at least one second castor rear wheel mechanically coupled to the second rear lower frame;

a second folding point arranged between the second front lower frame and the second rear lower frame; wherein the second folding point permits the second front lower frame to fold upon the second rear lower frame

at least one second strut connected to the second rear lower frame and the second front lower frame; wherein the at least one second strut limits the second front lower frame moving away from the second rear lower frame;

wherein the at least one first castor rear wheel, the at least one second castor rear wheel, the at least one first fixed front wheel and the at least one second fixed front wheel enable a turn radius while the human user is walking forward

a seat rest mechanically coupled to the first front lower frame and the second front lower frame;
