A collapsible walking device that can be disposed in an operative (open) configuration and a storage (closed) configuration. The open, operative configuration of the walking device provides a structure to aid a user in walking or standing. The closed, storage configuration allows for easy and convenient storage and transport of the walking device. The collapsible walking device can be transitioned from the operative configuration to the storage configuration in one motion. The walking device includes four support legs that extend to the ground from adjacent two handles.

1. A walking device to provide mobility support for a user and configured to be disposed in an operative configuration and a storage configuration, the walking device comprising: first and second handles configured to be grasped by and support the user;first and second handle legs that extend from the first and second handles, respectively, toward the ground and configured to be forward of the user in the operative configuration;first and second rearward-facing support legs extending toward the ground and pivotably coupled to the first and second handle legs, respectively, the first and second rearward-facing support legs configured to also extend at an angle back toward the user in the operative configuration;first and second cross bars, each cross bar pivotably coupled to the first and second handle legs, the first and second cross bars intersecting adjacent each other and pivotably coupled to each other; anda pivot support extending from the first rearward-facing support leg to the second rearward-facing support leg, the pivot support comprising first and second pivoting bars and a latch mechanism, the first pivoting bar coupled directly to the first rearward-facing support leg and to the latch mechanism and the second pivoting bar coupled directly to the second rearward-facing support leg and to the latch mechanism, the latch mechanism configured to secure the first and second pivoting bars in a substantially linear arrangement in the operative configuration;wherein the handle legs, rearward-facing support legs, cross bars, pivot support and respective interconnecting joints are configured to permit the walking device to move from the operative configuration to the storage configuration in a single motion by pulling upward on the latch mechanism toward the handles, which simultaneously brings the first and second handles, the first and second handle legs, and the first and second rearward-facing support legs toward each other and the rearward-facing support legs toward the handle legs. 2. A walking device of claim 1, the latch mechanism further configured to allow the first and second pivoting bars to pivot toward each other to a substantially parallel arrangement in the storage configuration. 3. A walking device of claim 1, the latch mechanism further comprising a release tab to unlock the latch mechanism from securing the first and second pivoting bars in the substantially linear arrangement of the operative configuration. 4. A walking device of claim 1, further comprising first and second stabilizing bars, the first stabilizing bar pivotably coupled to the first handle leg and the first rearward-facing support leg and the second stabilizing bar pivotably coupled to the second handle leg and the second rearward-facing support leg. 5. A walking device of claim 1, further comprising a first slidably moveable joint to couple the second cross bar to the first handle leg at a location along the first handle leg spaced apart from the handle and a second slidably moveable joint to couple the first cross bar to the second handle leg, wherein each slidably moveable joint is configured to slidably move along the length of the respective handle leg as the walking device is transitioned between the operative configuration and the storage configuration. 6. A walking device of claim 5, wherein the first slidably moveable joint also couples a first stabilizing bar to the first handle leg and the second slidably moveable joint also couples a second stabilizing bar to the second handle leg. 7. A walking device of claim 1, wherein the first and second rearward-facing support legs comprise a bend configured to enable the first and second stabilizing bars respectively to be disposed parallel to and between the first and second rearward facing support legs and the first and second handle legs respectively, when the walking device is in the storage configuration. 8. A walking device of claim 1, further comprising first and second wheeled tips disposed at an end of the first and second handle legs, respectively, opposite the first and second handles and proximate to the ground. 9. A walking device of claim 1, further comprising first and second telescoping height adjustment mechanisms to enable adjustment of the length of the first and second handle legs respectively, and thereby adjust the height of the first and second handles from the ground. 10. A walking device of claim 9, wherein the first and second telescoping height adjustment mechanisms comprise: a telescoping tube configured to be slidably moveable relative to the respective handle leg;a button pivoting component comprising a pin disposed at a first end of the button pivoting component and a button portion disposed at a second end of the button pivoting component such that the pin and button portion can rotate about a pivot point positioned between the pin and the button portion, wherein the pin is configured to engage a hole in the telescoping tube and a hole in the handle leg to secure the position of the telescoping tube relative to the respective handle leg, wherein the button pivoting component is biased to pivot toward engagement by the pin of the holes to secure the telescoping tube relative to the handle leg, and wherein depressing the button disengages the pin from the holes to allow the telescoping tube to slidably move relative to the respective handle leg; anda stationary pivot component secured to the respective handle leg and providing a pivot point about which the button pivoting component pivots. 11. A walking device of claim 10, wherein the telescoping tube is configured to be received within the handle leg and comprises a plurality of aligned holes spaced along a portion of a length of the telescoping tube, wherein the height of the handle leg can be adjusted by disengaging the pin from a first hole of the plurality of holes in the telescoping tube, sliding the telescoping tube relative to the handle leg, and engaging the pin in a second hole of the plurality of holes in the telescoping tube. 12. A walking device of claim 10, wherein the telescoping tube is configured to receive the handle leg, and wherein the handle leg comprises a plurality of aligned holes spaced along a portion of a length of the handle leg, wherein the height of the handle leg can be adjusted by disengaging the pin from a first hole of the plurality of holes in the handle leg, sliding the telescoping tube relative to the handle leg, and engaging the pin in a second hole of the plurality of holes in the handle leg.
