Dust collection assembly and a tensioning system for a saw

摘要

A saw (100) includes a sawdust collection assembly (2) having a chute (10) made of a material having a stretchability to be shaped responsive to movement of a blade housing (102) into a moveable sawdust path. An upper end (40) of a top portion (6) of the chute (10) is removably and reattachably engaged with a top attachment member (36) mounted to the blade housing (102). A bottom portion (8) of the chute (10) is removably and reattachably engaged with a bottom attachment member (26) mounted to a rear side (106C) of a fence (106) of the saw (100). Two side edges (44, 46) of the top portion (6) are respectively attached by two side tension cords (18) to left and right sides (106B, 106A) of the fence (106). One of the side tension cords (18) can be used with a tension block (20, 28) to form a tensioning system.

主权项

1. A sawdust collection assembly, comprising, in combination:
a chute including a top portion and a bottom portion, with the top portion including an upper end, with the bottom portion including a bottom end spaced from the upper end of the top portion along a first axis, with the top portion further including first and second side edges spaced from each other along a second axis perpendicular to the first axis, with the chute formed of a material having a stretchability to be shaped responsive to movement of a blade housing of a saw into a moveable sawdust path, with the moveable sawdust path adapted to be in communication with a dust evacuation port in the blade housing of the saw; a top attachment member being flexible and adapted to be mounted to the blade housing of the saw and having a shape approximating the blade housing, with the upper end of the top portion removably and reattachably engaged with the top attachment member; a bottom attachment member adapted to be mounted to a rear side of a fence of the saw and having a shape approximating the rear side of the fence, with the bottom attachment member being flexible, with the bottom portion removably and reattachably engaged with the bottom attachment member, with the bottom attachment member located below the top attachment member along the first axis; at least one first attachment location at the first side edge of the top portion; at least one second attachment location at the second side edge of the top portion; a first side tension cord including first and second ends, with the first end of the first side tension cord attached to the at least one first attachment location, with the fence of the saw including left and right sides on opposite sides of the rear side of the fence, with the second end of the first side tension cord adapted to be attached to the left side of the fence of the saw; and a second side tension cord including first and second ends, with the first end of the second side tension cord attached to the at least one second attachment location, with the second end of the second side tension cord adapted to be attached to the right side of the fence of the saw.
