Abstract

A dust shroud for reciprocating saws has a shroud body with bristles, a vacuum port and an attachment collar attached to the shroud body. The shroud has a slot formed through the collar and shroud body and is expandable and collapsible to fit different sizes of reciprocating saws.

Claims

1. A dust shroud for reciprocating saws comprising:

a shroud body having an upper surface and a peripheral skirt extending downwardly from the upper surface so as to form a dust collection chamber;

a conforming sidewall extending downwardly from the peripheral skirt;

a vacuum port attached to the shroud body and disposed in communication with the dust collection chamber;

an attachment collar extending upwardly from the upper surface of the shroud body;

a slot formed through the attachment collar, shroud body and bristles such that both the attachment collar and the shroud body can flex to thereby increase and decrease in diameter; and

an attachment strap disposed around the attachment collar, the attachment strap being tightenable to reduce the diameter of the attachment collar to thereby secure the shroud to a reciprocating saw.

2. The dust shroud of claim 1, wherein the dust shroud is attached to a reciprocating saw, the reciprocating saw having a generally linear and elongate body and having a blade extending from a front of the body in a direction which is collinear to the body.

3. The dust shroud of claim 2, wherein the dust shroud is attached to the saw such that the attachment collar is disposed in a direction parallel to the saw body and a bottom edge of the shroud body is disposed generally perpendicular to the blade.

4. The dust shroud of claim 2, wherein the saw has a front plate which contacts material being cut during use of the saw, and wherein the front plate is disposed distally from a lower edge of the shroud body.

5. The dust shroud of claim 1, wherein the shroud is selectively attachable to one a plurality of different sizes of reciprocating saws.

6. The dust shroud of claim 1, wherein the conforming side wall comprises bristles.

7. The dust shroud of claim 1, wherein the vacuum port is disposed on a first side of the shroud body and the slot is disposed on a second side of the shroud body generally opposite the first side.

8. A dust shroud for a reciprocating saw, the reciprocating saw having an elongate generally linear body and a blade extending outwardly from a front end of the body in a direction collinear with the body, the dust shroud comprising:

a shroud body, the shroud body having;

an upper surface;

a peripheral wall extending downwardly from the upper surface to create a dust collection chamber;

a bottom edge of the peripheral wall;

an attachment structure extending upwardly from the shroud body;

a vacuum port attached to the shroud body and disposed in communication with the dust collection chamber to draw dust therefrom; and

wherein, when the dust shroud is attached to the saw the bottom edge of the peripheral wall is disposed generally perpendicular to the blade and to the body of the saw.

9. The dust shroud of claim 8, wherein the attachment structure comprises a collar.

10. The dust shroud of claim 8, further comprising a slot formed completely through a side of the shroud body.

11. The dust shroud of claim 10, wherein the slot is between about 0.5 and 1 inch wide.

12. The dust shroud of claim 8, wherein, when the shroud is attached to the saw, a front work contacting plate is positioned beyond the bottom edge of the shroud body.

13. The dust shroud of claim 8, further comprising bristles extending from the bottom edge of the shroud body.

14. The dust shroud of claim 13, wherein, when the shroud is attached to the saw, a front work contacting plate is positioned adjacent the middle of the bristles.

15. The dust shroud of claim 14, wherein the bristles are about 2 inches long.

16. The dust shroud of claim 8, wherein the shroud body has a slot formed through a side thereof, and wherein the shroud body changes size due to expansion and contraction of the shroud body at the slot.
