Claims20
A personal mobility device, comprising:
- a deck;
- wheels disposed at opposing ends of the deck;
- a pole extending at a proximal end from a first wheel of the wheels;
- and
- a handle disposed at a distal end of the pole;
- wherein the deck includes:
- a deck hinge disposed between a first deck end and a second deck end;
- and
- a deck latch operably connected to the deck hinge to retain the deck in an extended position and configured such that releasing of the deck latch allows for folding of the deck about the deck hinge toward a folded position;
- further comprising:
- a first wheel bracket connecting the first wheel to the deck;
- and
- a second wheel bracket connecting a second wheel of the wheels to the deck;
- wherein the deck latch is operably connected to first wheel bracket and the second wheel bracket such that releasing of the deck latch allows for rotation of the first wheel bracket and the second wheel bracket relative to the deck;
- wherein the deck latch includes:
- a latch body rotatable about a latch body axis;
- a deck lock arm extending from the latch body and configured for engagement with a complimentary deck tab to retain the deck in the extended position;
- a first wheel release arm extending from the latch body and operably connected to the first wheel bracket to selectably release the first wheel bracket via operation of the deck latch;
- and
- a second wheel release arm extending from the latch body and operably connected to the second wheel bracket to selectably release the second wheel bracket via operation of the deck latch;
- and
- wherein the first wheel release arm and the second wheel release arm are operably connected to the first wheel bracket and the second wheel bracket via one of a wire or a strap.
A personal mobility device, comprising:
- a deck;
- wheels disposed at opposing ends of the deck;
- and
- a pole extending at a proximal end from a first wheel of the wheels;
- wherein the pole includes:
- a lower pole portion operably connected to the first wheel;
- an upper pole portion operably connected to the lower pole portion and to a handle, the upper pole portion configured to be selectably movable in the lower pole portion to shorten a length of the pole;
- and
- a pole latch operably connected to the lower pole portion, the pole latch configured to retain the pole in an upright position relative to the deck and allow for folding of the pole toward the deck when the pole latch is released;
- wherein the pole latch is configured to be automatically released when the upper pole portion is lowered into the lower pole portion.
