Abstract

A yard blower is provided which includes a housing mounting a source of high volume pressurized air, a hose fluidly communicating with the housing for directing the pressurized air, a nozzle with a rear end connected with the hose for distributing the pressurized air. The nozzle has a front end with an opening for releasing the pressurized air. The nozzle also has a generally rigid rake formed by a plurality of spaced apart tines projecting from the nozzle allowing the nozzle to agitate yard debris.

Claims

1. A nozzle for an air yard blower comprising:

a rear end for connection with a high volume source of pressurized air, said rear end having a rear opening for receipt of pressurized air;

a front end fluidly communicating with said rear end, said front end having a front opening whereby said front opening is generally vertical having a top edge and a bottom edge for releasing said pressurized air in a transversely divergent manner; and

a generally rigid rake formed by a plurality of spaced apart tines whereby said tines are generally coplanar to said front opening of said nozzle, said tines are adjacent to said bottom edge and project downwardly from said bottom edge allowing said nozzle to agitate yard debris.

2. A nozzle as described in claim 1 wherein said tines are integral with said nozzle.

3. A nozzle as described in claim 1 wherein said rake is removable.

4. A nozzle as described in claim 1 wherein said rake is held to said nozzle by a clip.

5. A nozzle as described in claim 4 wherein there are a plurality of clips.

6. A nozzle as described in claim 4 wherein said clip is metallic.

7. A nozzle as described in claim 4 wherein said clip has a snap connection with said nozzle.

8. A nozzle as described in claim 7 wherein said nozzle has a ramp with front and rear edges and said clip has a tab that is stopped by said ramp rear edge.

9. A nozzle as described in claim 8 wherein said clip has a bend for riding up said nozzle ramp front edge.

10. A nozzle as described in claim 4 wherein said clip has a snap connection with said rake.

11. A nozzle as described in claim 4 wherein said clip has a generally S shape.

12. An air yard blower comprising:

a housing mounting a high volume source of pressurized air;

a hose fluidly communicating with said housing for directing said pressurized air;

a nozzle connected with said hose for distributing said pressurized air, said nozzle including;

a rear end having an opening for connection with said hose;

a front end fluidly communicating with said rear end, said front end having an opening for releasing said pressurized air in a divergent manner, and said front end opening having a bottom edge;

a generally rigid rake formed by a plurality of spaced apart tines projecting from said front end bottom edge allowing said nozzle to agitate yard debris.

13. A air yard blower as described in claim 12 wherein said nozzle rake forks project generally horizontally outward and then generally vertically downward.

14. A nozzle for an air yard blower comprising:

a rear end for connection with a high volume source of pressurized air, said rear end having an opening for receipt of pressurized air;

a front end fluidly communicating with said rear end, said front end having an opening for releasing said pressurized air; and

a generally rigid rake formed by a plurality of spaced apart tines whereby said tines project generally horizontally outward and then generally vertically downward from said nozzle front end allowing said nozzle to agitate yard debris.

15. A nozzle for an air yard blower comprising:

a rear end for connection with a high volume source of pressurized air, said rear end having an opening for receipt of pressurized air;

a front end fluidly communicating with said rear end, said front end having an opening for releasing said pressurized air; and

a generally rigid rake formed by a plurality of spaced apart tines projecting from said nozzle front end allowing said nozzle to agitate yard debris, said rake being held by a clip, and said clip has a snap connection with said rake.

16. A nozzle as described in claim 15 wherein said clip has a snap connection with said nozzle.

17. A nozzle as described in claim 15 wherein said rake has a slot with a mound and said clip is captured within said slot.

18. A nozzle as described in claim 17 wherein said rake slot has an overhang.

19. A nozzle for an air yard blower comprising:

a rear end for connection with a high volume source of pressurized air, said rear end having an opening for receipt of pressurized air;

a front end fluidly communicating with said rear end, said front end having an opening for releasing said pressurized air; and

a generally rigid rake formed by a plurality of spaced apart tines projecting from said nozzle front end allowing said nozzle to agitate yard debris and wherein said rake is held to said nozzle by a clip, said clip having a generally S shape.

20. A nozzle as described in claim 19 wherein said clip is metallic.
