A pivot shaft assembly for a foldable device includes a base seat, a shaft member and a locking member. The base seat has a through hole and an engaging portion. The shaft member extends through the through hole, includes a fixed tubular piece with a radial hole, and is rotatable relative to the base seat. The locking member includes a locking portion movably disposed in the radial hole. The locking portion is movable through the radial hole to engage with the engaging portion to position the pivot shaft assembly in a locked state so as to prevent rotation of the shaft member relative to the base seat, and is movable inwardly of the fixed tubular piece to disengage from the engaging portion to make the pivot shaft assembly in a released state so as to permit rotation of the shaft member relative to the base seat.

A cane also serves as a massager, including: a cane head, which includes a grip portion and an inserting and joining portion, the grip portion being gripped and held by a hand of a user, the inserting and joining portion having one end connected to one side of the grip portion, a free end of the inserting and joining portion including a massage sphere; a cane body, the inserting and joining portion of the cane head being mounted, in a detachable manner, in an interior of a top end of the cane body; and a support base, which is mounted, in a detachable manner, to a bottom end of the cane body for supporting on ground. When the cane head and the cane body are detached, the massage sphere can be used by the user to serve as a tool for massaging the body to thereby enhance convenience of use.

Apparatus and associated methods relate to distributing a laterally distributed load applied by a flexible surface to one or more longitudinal load paths. A support connection hub may, for example, include a first cavity extending longitudinally along a first axis and configured to receive a vertical support member at a bottom side of the support connection hub. The hub may, for example, include a second cavity extending across a top of the hub along a second axis orthogonal to the first axis. The second cavity may, for example, be horizontally and releasably receive a lateral support member orthogonal to the vertical support member such that the lateral rod is configured to support a flexible surface distributed along the lateral rod. Various embodiments may advantageously transfer a load from the flexible surface to the vertical rod along a load path substantially parallel to the first longitudinal axis.

A folding crutch chair includes a pivot base unit and at least three support leg units. The pivot base unit has at least three mounting slots angularly spaced apart from one another about an axial line, and at least three pairs of joint portions respectively formed in the mounting slots. Each support leg unit includes a pivot seat, an outer tubular piece, and an inner tubular piece extending telescopically relative to the outer tubular piece. The pivot seat has a pair of pivot portions respectively and pivotably connected with the joint portions such that each support leg unit is rotatable relative to the pivot base unit. The support leg units are shiftable between a folded state and an unfolded state. The length of the support leg units is reduced when folded so as to facilitate packaging, storage and carrying.

A folding crutch chair includes a pivot base unit, a primary leg unit, at least two support leg units, a positioning unit and a seating unit. The leg units are mounted on the pivot base unit. The positioning unit is mounted on the primary leg unit, and has a mounting seat and a positioning member. The positioning member has a guiding slope surface. A seating member of the seating unit is shiftable between a collapsed position and a seated position. During the operation from the seated position to the collapsed position, the seating member is actuated to move the guiding slope surface to generate a retention force for keeping the seating member unmoved relative to the positioning member so as to facilitate the folding operation.
