Kappsäge mit Parallelogramkonstruktion

摘要

A saw (10) comprises a frame, a table (12) mounted in the frame and adapted to adopt two positions. A pivot member (14) is on a first side of the table and a saw assembly (16) is pivoted (at 18) to the pivot member. A blade (26) is journalled in the assembly and a motor (22) drives the blade. An upper guard (32) covers an upper portion of the blade and is pivoted to the assembly, while a lower guard (40) covers a lower portion of the blade. A slot in the table permits the blade to protrude through the table. In a first of said two positions of the table, the saw assembly is above the table and the saw is a chop saw for performing plunge cuts on workpieces supported on said first side of the table (Figure 1). In a second of said two positions, the saw assembly is below the table and the saw is a bench saw for performing cuts on workpieces passed through the blade on a second opposite side of the table (Figure 2). A parallelogram lever (34) has a pivotal connection to the pivot member (at 38) and upper guard (at 36) whereby the orientation of the upper guard to the table is maintained. An extension (118) of the parallelogram lever has a rack (150) which, in bench saw mode, engages a worm gear (152) turnable by a knob to effect an adjustment to the depth of cut of the blade.
