Abstract

A suction line has a stiff suction tube and a flexible suction hose having a connecting end. A connector for connecting the connecting end of the flexible suction hose to the stiff suction tube to form the suction line having free ends is provided. One of the free ends of the suction line is connected to a vacuum source. The other free end of the suction line can receive a vacuuming tool. The stiff suction tube has a longitudinal axis. The connector is rotatable about an axis extending transverse to the longitudinal axis.

Claims

1. A suction line comprising:

a stiff suction tube;

a flexible suction hose having a connecting end;

a connector for connecting said connecting end of said flexible suction hose to said stiff suction tube to form said suction line having free ends;

one of said free ends of said suction line connected to a vacuum source;

another of said free ends of said suction line having means for receiving a vacuuming tool;

said stiff suction tube having a longitudinal axis;

said connector being rotatable about an axis extending transverse to said longitudinal axis.

2. A suction line according to claim 1, wherein said axis of rotation is perpendicular to said longitudinal axis.

3. A suction line according to claim 2, wherein said axis of rotation intercepts said longitudinal axis.

4. A suction line according to claim 1, wherein said connector is rotatable about an angle of 360°

and beyond.

5. A suction line according to claim 1, further comprising a cylindrical housing connected to said stiff suction tube, wherein said connector is rotatably connected to said cylindrical housing.

6. A suction line according to claim 5, wherein said cylindrical housing comprises a separator for coarse dust particles entrained in a suction stream generated by the vacuum source.

7. A suction line according to claim 5, wherein said cylindrical housing has a center axis and wherein said flexible suction hose opens into said cylindrical housing coaxially to said center axis.

8. A suction line according to claim 5, wherein said cylindrical housing has a center axis and wherein said flexible suction hose opens into said cylindrical housing in a radial direction relative to said center axis.

9. A suction line according to claim 5, wherein said connector has a connecting member and wherein said connecting end of said flexible suction hose is detachably connected to said connecting member.

10. A suction line according to claim 5, wherein said stiff suction tube opens radially into said cylindrical housing.

11. A suction line according to claim 5, wherein said stiff suction tube opens into said cylindrical housing in the direction of a secant at said cylindrical housing.

12. A suction line according to claim 5, wherein said flexible suction hose has a mouth opening into said cylindrical housing and wherein said cylindrical housing comprises a filter element covering said mouth.

13. A suction line according to claim 1, wherein said stiff suction tube and said flexible suction hose extend substantially parallel to one another.

14. A suction line according to claim 1, wherein said stiff suction tube is a telescoping tube.

15. A suction line according to claim 1, wherein said stiff suction tube forms a guide rod for a vacuum cleaner.
