Document Type and Number:
Japanese Patent JP4944097
Kind Code:
B2
Abstract:
A device for cutting sheet metal is disclosed. The device comprises of a cutting blade (13) which passes between two curved sharpened support blades (12 & 14) ("curved support blades"), the latter which curves away from the cutting blade (13). The cutting blade (13) and the curved support blades (12 & 14) each have two holes in them (henceforth referred to as upper and lower holes) which enable them to be connected together and to the handles (4 & 5). The handles (4 & 5) are long and similar to those commonly used in long handle pruning secateurs. Items (3 & 6) each have two holes in them (henceforth referred to as upper and lower holes) which enable them to be connected together and to the cutting blade (13) and the curved support blades (12 & 14). Items (3 & 6) are bolted together at their upper holes, and at the other ends they slot into the handles (4 & 5). The cutting blade (13) and the two curved support blades (12 & 14) are bolted together at their upper holes, with the cutting blade (13) fitting between the two curved support blades (12 & 14). The two curved support blades (12 & 14) are connected to either side of item (6), and they are all bolted together at their respective lower holes. The cutting blade (13) is bolted to item (3) at the lower holes of both items. The two curved support blades (12 & 14) are held together by a bracket (1) which keeps the former parallel to each other and demarcates the space for which the cutting blade (13) passes through. The cutting blade (13) is straight, however the face of the blade is angled to one side to assist with the cutting.
