Wet cleaning suction nozzle
First Claim
1. A wet cleaning suction nozzle comprising a nozzle part (11) defining at least one suction opening (22) facing the floor and communicating with a nozzle outlet tube (12), a pair of scraper blades (24) secured to said nozzle part, one of said blades being placed in front of the suction opening as seen in the direction of movement of the nozzle and the other of said blades being placed in behind of the suction opening as seen in the direction of nozzle movement, a lower end of the scraper blades abutting the floor when the nozzle is used, wherein the suction opening (22) is in a fixed position relative to fastening points (23) of the scraper blades in the nozzle and is located vertically closer to the floor than said fastening points (23) are vertically located from the level of said suction opening, and wherein the nozzle is intended to be used on hard as well as soft floors, the nozzle part comprising at least one spacer (31) which rides upon and holds the nozzle opening (22) above the floor when the nozzle is used on a hard floor but which sinks into a soft floor covering and thereby permits the suction opening to abut the floor covering when the nozzle is used on a soft floor.

Abstract
A wet cleaning suction nozzle having a suction opening (22) facing the floor and communicating with a nozzle outlet tube (12), scraper blades (24), one located in front of, and one behind, the suction opening as seen in the direction of movement of the nozzle, wherein the lower ends of the scraper blade abut the floor when the nozzle is used. The suction opening (22) is located closer to the floor than fastening points (23) of the scraper blades in the nozzle. The nozzle is used on hard, as well as soft floors, without being converted, and the nozzle includes spacers (31), which prevent the nozzle opening (22) from touching the floor when the nozzle is used on a hard floor, but which permits the suction opening to abut the floor when the nozzle is used on a soft floor.

- 1. A wet cleaning suction nozzle comprising a nozzle part (11) defining at least one suction opening (22) facing the floor and communicating with a nozzle outlet tube (12), a pair of scraper blades (24) secured to said nozzle part, one of said blades being placed in front of the suction opening as seen in the direction of movement of the nozzle and the other of said blades being placed in behind of the suction opening as seen in the direction of nozzle movement, a lower end of the scraper blades abutting the floor when the nozzle is used, wherein the suction opening (22) is in a fixed position relative to fastening points (23) of the scraper blades in the nozzle and is located vertically closer to the floor than said fastening points (23) are vertically located from the level of said suction opening, and wherein the nozzle is intended to be used on hard as well as soft floors, the nozzle part comprising at least one spacer (31) which rides upon and holds the nozzle opening (22) above the floor when the nozzle is used on a hard floor but which sinks into a soft floor covering and thereby permits the suction opening to abut the floor covering when the nozzle is used on a soft floor.
- 4. A wet cleaning suction nozzle comprising a nozzle part (11) defining at least one suction opening (22) facing the floor and communicating with a nozzle outlet tube (12), a pair of scraper blades (24) pivotally secured to said nozzle part, one of said blades being placed in front of the suction opening as seen in the direction of movement of the nozzle and the other of said blades being placed behind the suction opening as seen in the direction of nozzle movement, a lower end of the scraper blades abutting the floor when the nozzle is used, wherein the suction opening (22) is located relatively closer to the floor than fastening points (23) of the scraper blades in the nozzle and wherein the nozzle is intended to be used on hard as well as soft floors, the nozzle part comprising at least one spacer (31) which rides upon and holds the nozzle opening (22) above the floor when the nozzle is used on a hard floor but which sinks into a soft floor covering and thereby permits the suction opening to abut the floor covering when the nozzle is used on a soft floor.

7. A wet cleaning suction nozzle comprising a nozzle part (11) defining at least one suction opening (22) facing the floor and communicating with a nozzle outlet tube (12), a pair of scraper blades (24) secured to said nozzle part, one of said blades being placed in front of the suction opening as seen in the direction of movement of the nozzle and the other of said blades being placed in behind of the suction opening as seen in the direction of nozzle movement, a lower end of the scraper blades abutting the floor when the nozzle is used, wherein the suction opening (22) is in a fixed position relative to fastening points (23) of the scraper blades in the nozzle and is located relatively closer to the floor than said fastening points (23) and wherein the nozzle is intended to be used on hard as well as soft floors, the nozzle part comprising at least one space (31) which rides upon and holds the nozzle opening (22) above the floor when the nozzle is used on a hard floor but which sinks into a soft floor covering and thereby permits the suction opening to abut the floor covering when the nozzle is used on a soft floor, and further comprising means (14) for distributing liquid to the floor.
- 9. A wet cleaning suction nozzle comprising a nozzle part (11) defining at least one suction opening (22) facing the floor and communicating with a nozzle outlet tube (12), a pair of scraper blades (24) secured to said nozzle part, one of said blades being placed in front of the suction opening as seen in the direction of movement of the nozzle and the other of said blades being placed in behind of the suction opening as seen in the direction of nozzle movement, a lower end of the scraper blades abutting the floor when the nozzle is used, wherein the suction opening (22) is in a fixed position relative to fastening points (23) of the scraper blades in the nozzle and is located relatively closer to the floor than said fastening points (23) and wherein the nozzle is intended to be used on hard as well as soft floors, the nozzle part comprising at least one spacer (31) which rides upon and holds the nozzle opening (22) above the floor when the nozzle is used on a hard floor but which sinks into a soft floor covering and thereby permits the suction opening to abut the floor covering when the nozzle is used on a soft floor, wherein said nozzle part comprises a surface which is used for drying or mechanically treating the floor.
- 13. A wet cleaning suction nozzle comprising a nozzle part (11) defining at least one suction opening (22) facing the floor and communicating with a nozzle outlet tube (12), a pair of holders secured to said nozzle part, each of said holders defining an elongated recess and a slot, a pair of scraper blades (24) pivotally secured to an associated one of said pair of holders and having an upper end defining a bead which is received within the holder elongated recess, one of said scraper blades being placed in front of the suction opening as seen in the direction of movement of the nozzle and the other of said blades being placed behind the suction opening as seen in the direction of nozzle movement, a lower end of the scraper blades abutting the floor when the nozzle is used, wherein the suction opening (22) is located relatively closer to the floor than fastening points (23) of the scraper blades in the holders and wherein the nozzle is intended to be used on hard as well as soft floors, the nozzle part comprising at least one spacer (31) which rides upon and holds the nozzle opening (22) above the floor when the nozzle is used on a hard floor but which sinks into a soft floor covering and thereby permits the suction opening to abut the floor covering when the nozzle is used on a soft floor.
