Title
(EN) AMBULATORY WHEELSTAND
(FR) SUPPORT ROULANT AMBULATOIRE
Abstract
(EN)
An ambulatory wheelstand (10) includes a user support structure (32) pivotably attached to a wheeled frame (12). The frame (12) includes a pair of large diameter drive wheels (26) and a pair of front castor wheels (3). The user support structure (32) includes hinge pins (46) which are entrained in elongated horizontal slots (28) in the frame (12). A pivot arm (48) also connects the support structure (32) to the frame (12) so that the structure can pivot between an upright (Figure 4) and a prone position (Figure 5). As the support structure (32) is lowered to a prone position, the hinge pin (46) slides rearwardly in the elongated slot (28) to prevent the center of gravity from shifting too far forward. Conversely, when in the upright position, the hinge pin (46) slides to the forward end of the slot (28), maintaining the center of gravity in substantially the same position.
(FR)
Le support roulant ambulatoire (10) comprend une structure de support (32) pour l'utilisateur, laquelle est fixée de manière pivotante à un châssis à roues (12). Le châssis (12) comprend une paire de roues d'entraînement de grand diamètre (26) et une paire de roulettes avant (3). La structure de support de l'utilisateur (32) comprend des goupilles d'articulation (46) qui sont entraînées dans des fentes allongées horizontales (28) du châssis (12). Un bras de pivotement (48) relie également la structure de support (32) au châssis (12) de sorte que la structure peut pivoter entre une position droite (Fig. 4) et une position horizontale (Figure 5). En abaissant la structure de support (32) jusqu'à sa position horizontale, la goupille d'articulation (46) coulisse vers l'arrière dans la fente allongée (28) pour empêcher que le centre de gravité ne se déplace trop vers l'avant. Inversement, lorsqu'elle se trouve dans la position droite, la goupille d'articulation (46) coulisse vers l'extrémité antérieure de la fente (28), maintenant ainsi le centre de gravité sensiblement dans la même position.
