<p>Walkers incorporating seats are usually somewhat complicated, expensive structures. A simple, lightweight walker/ seat combination is formed of tubular metal and includes a pair of inverted U-shaped sides interconnected by a first crossbar, the sides defining front and rear legs, the first crossbar being pivotally connected to the rear legs so that the sides can be rotated around the ends of the crossbar between a closed or folded, storage position in which the sides are in overlapping relationship to each other, and an open, use position in which the sides are prarallel to each other; a wheel on the bottom of each rear leg vertically movable so that the walker does not move when in use as a seat; a second, extensible crossbar extending between the sides in front of the first crossbar; a first latch on the second crossbar for latching such crossbar in an extended condition and consequently latching the sides in the parallel, use position; a seat pivotally connected to the first crossbar for rotation between a more or less vertical, storage position and a horizontal use position; and a second latch on the seat for supporting the seat in the horizontal, use position, and for latching the seat in the storage position.</p> |
