A method of manufacturing a patient aid device, such as a walker, includes the steps of molding a polymer or plastic connector (60) over first and second metal structural members (22, CB) to maintain the structural members in a first geometrical relationship. After the plastic has cured, the method includes the step of rotating the first structural member or front leg (22) relative to the plastic connector (60) to form an integral hinge without any seam in the plastic. The resultant walker includes front legs (22) hinged via the connectors (60) at opposite ends of the front cross brace (CB). The connector (60) includes first tubular portion (62), flange (64) cooperative with support member (122), second tubular portion (66) and gusset (90) between the first and second tubular portions (62, 66).

L'invention concerne un procédé de fabrication d'un dispositif d'aide pour patients, tel qu'un cadre de marche (W). Ledit procédé comprend les étapes consistant à mouler un élément de liaison plastique ou polymère (60) sur des premier et second éléments de structure métalliques (22, CB) pour maintenir les éléments de structure dans une première relation géométrique. Après durcissement du plastique, le procédé comprend l'étape consistant à tourner le premier élément de structure ou pied avant (22) relativement à l'élément de liaison plastique (60) afin de former une charnière solidaire par construction sans aucune bavure dans le plastique. Le cadre de marche ainsi obtenu comprend des pieds avant (22) articulés par l'intermédiaire des éléments de liaison (60) à des extrémités opposées de la traverse de devant (CB). Le pied arrière (22) et le pied avant (24) de chaque cadre latéral (SF1, SF2) du cadre de marche sont reliés entre eux par une traverse inférieure (40) qui présente du plastique moulé de préférence autour de la périphérie entière de chaque pied.
