CA 2305791

A folding handle device (10) is disclosed, mountable to an article to be carried, having a rotatable U-shaped handle (20) with leg members adaptable to pivotally receive a mounting shaft (30), each leg member having a base having planar surfaces (23, 25) such that the handle can be held upright or folded. The device further includes two mounting shafts rotatably mounted to the handle through apertures in a planar mounting surface (70) and are retained in place by a nut (50). A spring (40) between the nut and the bottom side of the mounting surface bias the mounting shaft away from the planar mounting surface. The handle is adapted to facilitate axial movement of the shafts relative to and perpendicular to the planar mounting surface as the handle is rotated between the upright and folded positions, wherein when the handle is either in the upright or folded position, the spring is under a compressive load, and during the transition from folded to upright positions, the spring is under a greater compressive load than that when the handle is in the upright or folded position.

Ce dispositif de poignée pliante (10), qui se monte sur un article à transporter, comporte une poignée en U tournante (20) dont les bras peuvent s'adapter en vue de la réception pivotante d'un arbre de montage (30). Chaque bras comporte une base présentant des surfaces planes (23, 25) de façon que la poignée puisse être tenue redressée ou pliée. Le dispositif comporte en outre deux arbres de montage montés rotatifs sur la poignée via des orifices dans une surface de montage plane (70) et tenus en place par un écrou (50). Un ressort (40) monté entre l'écrou et le côté bas de la surface de montage a pour effet d'éloigner l'arbre de montage de la surface de montage plane. La poignée est conçue pour favoriser le mouvement axial des arbres de montage par rapport à et perpendiculairement à la surface de montage plane pendant les mouvements de rotation de la poignée entre les positons redressée et pliée. En l'occurrence, la poignée vient soit en position redressée, soit en position pliée, et lorsque la poignée est en position redressée ou en position pliée, le ressort subit une force en compression. En outre, lors de la transition de position pliée en position redressée, le ressort subit une force de compression supérieure à celle qui s'exerce lorsque la poignée est en position redressée ou en position pliée.
