Abstract

A universal dust shroud is mountable to many high speed gas powered concrete cutting saws while remaining strong and stable. The dust shroud is adjustable to properly fit the saw and effectively collect dust and debris.

Claims

1. A universal dust shroud for a high speed gas powered saw comprising:

a shroud body having an open bottom and having a slot formed in the front thereof for receiving a saw blade;

an exhaust port extending laterally from the shroud body;

a mounting collar attached to the exhaust port, the collar being selectively movable along the exhaust port, selectively rotatable relative to the exhaust port, and selectively attachable to the exhaust so as to prevent movement relative thereto;

mounting arms attached to the mounting collar and extending therefrom;

mounting clamps attached to the mounting arms and attachable to a high speed gas powered saw, and

wherein the mounting clamps are attachable to a handle of a high speed gas powered saw.

2. The dust shroud of claim 1, wherein the shroud body has a collar extending upwardly therefrom, the collar being positionable around a saw blade guard so as to locate the shroud body relative to the blade guard.

3. The dust shroud of claim 1, wherein the mounting clamps are mountable at a varying distance from the mounting collar along the mounting arms.

4. The dust shroud of claim 1, wherein the mounting arms extend generally perpendicularly to the exhaust port.

5. The dust shroud of claim 1, wherein the mounting collar has a plurality of mounting locations thereon, and wherein the mounting arms may be mounted to different of said plurality of locations.

6. The dust shroud of claim 1, wherein the saw has a saw blade oriented vertically and wherein the exhaust port extends laterally generally parallel to the axis of the saw blade.

7. A dust shroud for a saw, the saw comprising:

a saw blade disposed vertically;

a blade guard extending around an upper portion of the saw blade;

a saw body disposed behind the saw blade; and

a handle disposed adjacent the back of the saw blade;

the dust shroud comprising;

a shroud body disposed adjacent the rear of the saw blade and extending around a portion of the saw blade;

an exhaust port extending laterally from the shroud body, the exhaust port being in communication with an interior of the shroud body;

mounting arms attached to the exhaust port and attached to the handle; and

a collar extending upwardly from the shroud body, the collar having an open front, the collar extending around a portion of the blade guard.

8. The dust shroud of claim 7, wherein the shroud body comprises an open bottom, and wherein the shroud body comprises a slot formed through the front thereof and through a portion of the top thereof.

9. The dust shroud of claim 8, wherein a portion of the slot located in the front of the shroud body is wider than a portion of the slot located in the top of the shroud body.

10. The dust shroud of claim 7, wherein the top of the shroud is curved so as to direct air flow towards the exhaust port.

11. The dust shroud of claim 7, further comprising a mounting collar disposed around the exhaust port, wherein the mounting collar may be selectively moved along the exhaust port and selectively rotated about the exhaust port, and wherein the mounting collar may be selectively clamped in position on the exhaust port.

12. The dust shroud of claim 11, wherein the mounting arms attach to the mounting collar.

13. The dust shroud of claim 11, wherein the mounting arms may be attached to the mounting collar in a plurality of different positions and wherein the angle of the mounting arms relative to the mounting collar may be adjusted.

14. The dust shroud of claim 7, further comprising mounting clamps, the mounting clamps being selectively attachable to the mounting arms at different positions along the mounting arms and being attached to the handle so as to thereby attach the mounting arms to the handle.

15. A universal dust shroud for a high speed gas powered saw comprising:

a shroud body having an open bottom and having a slot formed in the front thereof for receiving a saw blade;

an exhaust port extending laterally from the shroud body;

a mounting collar attached to the exhaust port, the collar being selectively movable along the exhaust port, selectively rotatable relative to the exhaust port, and selectively attachable to the exhaust so as to prevent movement relative thereto;

mounting arms attached to the mounting collar and extending therefrom;

mounting clamps attached to the mounting arms and attachable to a high speed gas powered saw, and

wherein the shroud body has a collar extending upwardly therefrom, the collar being positionable around a saw blade guard so as to locate the shroud body relative to the blade guard.

16. A universal dust shroud for a high speed gas powered saw comprising:

a shroud body having an open bottom and having a slot formed in the front thereof for receiving a saw blade;

an exhaust port extending laterally from the shroud body;

a mounting collar attached to the exhaust port, the collar being selectively movable along the exhaust port, selectively rotatable relative to the exhaust port, and selectively attachable to the exhaust so as to prevent movement relative thereto;

mounting arms attached to the mounting collar and extending therefrom;

mounting clamps attached to the mounting arms and attachable to a high speed gas powered saw, and

wherein the mounting clamps are mountable at a varying distance from the mounting collar along the mounting arms.

17. A universal dust shroud for a high speed gas powered saw comprising:

a shroud body having an open bottom and having a slot formed in the front thereof for receiving a saw blade;

an exhaust port extending laterally from the shroud body;

a mounting collar attached to the exhaust port, the collar being selectively movable along the exhaust port, selectively rotatable relative to the exhaust port, and selectively attachable to the exhaust so as to prevent movement relative thereto;

mounting arms attached to the mounting collar and extending therefrom;

mounting clamps attached to the mounting arms and attachable to a high speed gas powered saw, and

wherein the mounting collar has a plurality of mounting locations thereon, and wherein the mounting arms may be mounted to different of said plurality of locations.

18. A universal dust shroud for a high speed gas powered saw comprising:

a shroud body having an open bottom and having a slot formed in the front thereof for receiving a saw blade;

an exhaust port extending laterally from the shroud body;

a mounting collar attached to the exhaust port, the collar being selectively movable along the exhaust port, selectively rotatable relative to the exhaust port, and selectively attachable to the exhaust so as to prevent movement relative thereto;

mounting arms attached to the mounting collar and extending therefrom;

mounting clamps attached to the mounting arms and attachable to a high speed gas powered saw, and

wherein the saw has a saw blade oriented vertically and wherein the exhaust port extends laterally generally parallel to the axis of the saw blade.
