Claims

A walking device for providing locomotion support for a user and configured to be disposed in a working configuration and a storage configuration, comprising:
first and second handles configured to be grasped by and support a user;
First and second extending toward the ground and configured to lie in front of the user on first and second sides, respectively, of the walking device in the operational configuration a leg ;
A support leg extending toward the ground and further at an angle toward the user on the first and second sides of the walking device, respectively , in the operational configuration. first and second rearwardly opposed support legs configured to extend rearwardly;
a seat positioned between the first side and the second side of the walking device;
a pull handle coupled to the seat;
has
said first handle positioned on a first side of said walking device and said second handle positioned on a second side of said walking device;
The first rearwardly facing support leg terminal end is coupled to and pivots relative to the first leg, and the second rearwardly facing support leg terminal end comprises: coupled to and pivoting relative to the second leg;
The leg , the first and second rearwardly opposed support legs , and the seat pull the pull handle upward toward the first and second handles, thereby with the first and second handles toward each other , the first and second legs toward each other , and the first and second rearwardly opposed support legs toward each other; Simultaneous movement of two rearwardly opposed support legs toward the first and second legs allows the walking device to change from the operating configuration to the storage configuration in a single motion. A walking device, configured to:

2. The apparatus of claim 1, further comprising first and second crossbars , wherein the first and second crossbars cross each other adjacently and are pivotally coupled to each other. walking device.

3. The walking device of claim 2, wherein at least one of said first and second crossbars is curved or bent.

The sheet is
first and second seat support bars , said pull handle and hinge mechanism, said first seat support bar being attached to said first rearwardly opposed support leg and to said hinge mechanism; , and said second seat support bar is pivotally connected to said second rearwardly facing support leg and to said hinge mechanism; first and second seat support bars and the hinge mechanism, wherein the hinge mechanism is configured to secure the first and second seat support bars in a substantially linear configuration in the operating configuration;
A walking device according to any preceding claim, comprising a first seat pad coupled to said first seat support bar and a second seat pad coupled to said second seat support bar. .

5. The hinge mechanism of claim 4, wherein the hinge mechanism is configured to allow the first and second seat support bars to pivot toward each other to a substantially parallel configuration in the storage configuration. walking device.

6. A pull handle according to claim 4 or 5, wherein the pull handle is configured to release the hinge mechanism from securing the first and second seat support bars in the substantially linear configuration of the operating configuration. A walking device as described.

a tip having first and second wheels respectively disposed at the ends of the first and second legs opposite the first and second handles and near the ground; and tips having third and fourth wheels disposed at the ends of the first and second rearwardly opposed support legs, respectively, near the ground. 7. The walking device according to any one of 1 to 6 .

It further includes first and second telescoping height adjustment mechanisms that allow adjustment of the heights of the first and second handles, respectively, thereby providing the height adjustment of the first and second handles from the ground. The walking device according to any one of claims 1 to 7 , which adjusts height.

9. The walking device of claim 8 , wherein the telescoping height adjustment mechanism comprises a telescoping tube, a handle and a pin.

said telescoping tube configured to be received within a handle leg and having a plurality of aligned holes spaced along a portion of the length of said telescoping tube; A height disengages the pin from a first of the plurality of holes in the telescoping tube to slide the telescoping tube relative to the handle leg; 10. The walking device of claim 9 , wherein adjustment is possible by engaging the pin within a second of the plurality of holes therein.

A walking device according to any preceding claim , wherein the pull handle forms a loop .

The walking device has a footprint having a width dimension and a depth dimension, wherein the width dimension and the depth dimension are determined when the walking device is in the operational configuration when the walking device is in the storage configuration. A walking device according to any one of claims 1 to 11 , which is smaller than the height.

A method of folding a walking device from an operational configuration to a storage configuration, comprising:
obtaining a collapsible walking device having first and second legs , first and second rearwardly opposing support legs, first and second crossbars, a seat, and individual interconnecting joints; ,
grasping the pull handle;
pulling the pull handle upward to collapse the collapsible walking device ;
A first interconnection joint couples the first leg to the first crossbar and the first rearwardly opposed support leg, and a second interconnection joint couples the second leg to the second support leg. coupled to the crossbar and the second rearwardly opposing support leg;
said first and second legs, rearwardly opposing support legs, crossbar, seat, and respective interconnecting joints transform said walking apparatus in a single motion from said operating configuration to said storage configuration; the first and second legs toward each other, the first and second rearwardly opposed support legs toward each other, and the first and second rearwardly opposed support legs toward each other , toward said first and second legs simultaneously via a first interconnection joint sliding along said first leg and a second interconnection joint sliding along said second leg. A method configured to allow locomotion .

14. The method of claim 13 , wherein the seat has a hinge mechanism configured to secure the seat in a linear configuration.

14. Pulling the pull handle upward comprises displacing a hinge mechanism upward, wherein the first seat support bar moves toward the second seat support bar . Or the method according to 14 .
