A foldable supporting device includes a linkage unit, a supporting unit and a converting unit. The supporting unit includes a main supporting member that has a first main supporting surface, and at least one auxiliary supporting member that has a first auxiliary supporting surface. The converting unit has at least one converting part that is drivable by movement of the linkage unit to convert the supporting unit between a folded state in which the first main supporting surface and the first auxiliary supporting surface cooperatively form a first angle, and an unfolded state in which the first main supporting surface and the first auxiliary supporting surface cooperatively form a second angle.

A folding mechanism includes a pivot seat unit and at least three support units disposed about an axial line and pivotally connected to the pivot seat unit. Each of the support units includes a support rod. Rotation of any one of the support rods of the support units relative to the pivot seat unit drives an adjacent one of the support rods to rotate, such that when any one of the support rods is rotated relative to the pivot seat unit, the other support rods are in turn driven to rotate relative to the pivot seat unit so as to convert the support units between a folded state and an unfolded state.

A convertible hiking stick includes a handle extending along a center axis and a first leg and a second leg that couple to the handle and extend along the center axis. The hiking stick is convertible into a tripod such that the first leg is in a first bore of the handle, the second leg is in a second bore of the handle, the first leg extends transverse to the second leg, and the first leg, the second leg, and the handle together support the hiking stick with respect to a surface.

A deformable crutch, includes a hand-held part, a seat part and a support part which are rotatably connected in sequence, and further includes a locking device for locking a rotation angle between the hand-held part and the seat part, and a rotation angle between the seat part and the support part. Rollers (34) are provided at the bottom of the deformed stool. A motor for driving the rollers (34) can also be mounted to deform the deformable crutch into an electric scooter.

A cane having: a primary leg with a top end and an opposed bottom end; a handle coupled to the top end of the primary leg; and at least two secondary legs that are each pivotably coupled to the primary leg between the top and bottom ends of the primary leg. Each of the at least two secondary legs is pivotable between a first, retracted position and a second, deployed position.
