Patent

CA 2194091

The invention relates to hand tools, particularly garden tools, such as for example garden spades, garden forks and the like. Such tools are known to have a fully forged operative end with an integral socket for connection to a handle. They have high strength but are expensive and require high levels of operator skills in their manufacture. Fabricated constructions from pressings deduce noticeably costs of production but at the expense of strength. The object of the invention is to provide such hand tools that have both acceptable cost factors and acceptable levels of strength. The objective is met by a construction comprising a blade/prong portion, a separately formed and forged frog, said separately formed and forged frog being suitably secured e.g. by welding, to the blade/prong portion and to a separately formed socket for connection to a handle.

'invention a rapport aux outils à main, particulièrement aux outils de jardinage, tels que les bêches de jardinage, les fourches à bêcher et autres outils semblables. Ces outils, tels qu'on les connaît, ont une extrémité de travail entièrement forgée comportant une douille intégrée à laquelle se fixe le manche. Ils sont très durables, mais dispendieux. En outre, leur fabrication exige une grande compétence. Les coûts de production des outils fabriqués par estampage sont réduits de façon significative, mais leur solidité en souffre. L'objectif de cette invention est de produire de tels outils à main dont les coûts et la solidité sont acceptables. L'objectif est satisfait en fabriquant un outil comportant une partie lame/tige et un ergot construit et forgé séparément, puis fixé solidement (p. ex. : par soudage) à la partie lame/tige et à une douille moulée séparément dans laquelle le manche sera introduit.
