An improved picture frame clamp assembly (40) includes an L-shaped screw plate (42), and an L-shaped backing plate (48). Both plates (42, 48) are elastically secured to each other by an elastic member (58), resulting in an L-shaped clamp assembly (40) with the screw plate (42) shifted slightly with respect to the backing plate (48). The screw plate (42) and the backing plate (48) each include two legs (44, 50). Each of these legs (44, 50) are sized to fit within a receiving channel (18) of a picture frame section (12). The magnitude of offset between the screw plate (42) and the backing plate (48) is larger than the width (W) of the receiving channel (18). This arrangement ensures that upon insertion into the receiving channel (18) of a frame section (12), the screw plate (42) will be biased against an inside wall (22) of the receiving channel (18), while the backing plate (48) will be biased against an opposing wall (20) of the receiving channel (18) due to the spring bias of the elastic member (58). The result is that each frame section is urged into tight engagement and alignment with the legs (44, 50) of the clamp assembly (40).

L'invention concerne un ensemble bride de fixation (40) amélioré pour cadre comprenant une plaque à vis (42) en forme de L et une contre-plaque (48) en forme de L, les deux plaques étant élastiquement fixées l'une à l'autre par un élément élastique (58), formant ainsi un ensemble bride de fixation (40) en forme de L, la plaque à vis (42) étant légèrement décalée par rapport à la contre-plaque (48). La plaque à vis (42) et la contre-plaque (48) comportent chacune deux pieds (44, 50), chacun dimensionné de façon à s'adapter à l'intérieur d'un canal de réception (18) d'une section de cadre (12). L'amplitude du décalage entre la plaque à vis (42) et la contre-plaque (48) est supérieure à la largeur (W) du canal de réception (18). Cet agencement assure que, dès son insertion dans le canal de réception (18) d'une section de cadre (12), la plaque à vis (42) sera poussée contre une paroi interne (22) du canal de réception (18), et la contre-plaque contre une paroi opposée (20) dudit canal de réception (18) du fait de la sollicitation des ressorts de l'élément élastique (58). Il en résulte que chaque section de cadre entre en contact et s'aligne avec les pieds (44, 50) de l'ensemble bride de fixation (40).
