Patent

CA 2220390

The hand tool has a shaft with a distal end which is configured to receive any one of a variety of different sized chisel or scraper blades or the like, via corresponding male and female dovetail connections, for example. Storage space for the extra blades, if desired, may be provided in the handle which is secured to the shaft, or may be provided via depressions in a panel of a tool case of the type commonly referred to as "gift cases". Where storage space is provided in the handle, preferably this is accomplished by virtue of a spring-loaded collar which overlies lower portions of elongated rotatable cover pieces, preventing rotation. When the spring-loaded collar is retracted, the cover pieces can be rotated, to reveal storage areas on either side of the handle.

Outil à main comportant une tige dont l'extrémité distale est conçue pour recevoir des lames de ciseaux ou de grattoirs de tailles diverses ou autres accessoires semblables, par l'intermédiaire, entre autres, d'adaptateurs mâles ou femelles en queue d'aronde correspondants. L'outil peut comporter un espace pour ranger des lames supplémentaires dans le manche, qui est fixé à la tige, ou être muni, dans des logements aménagés dans une partie, d'une boîte à outils généralement appelée « boîte cadeau ». Lorsqu'il y a un espace de rangement dans le manche, un collier à ressort de rappel est fixé sous les parties inférieures d'éléments de recouvrement allongés rotatifs, pour empêcher la rotation. Lorsque le collier à ressort de rappel est rétracté, les éléments de recouvrement peuvent être tournés pour dégager des espaces de rangement aménagés de chaque côté du manche.
