Abstract

A surface cleaning vacuum nozzle having a cleaning materials dispenser slidingly attached thereto, the entire assembly being connectable to a hand held suction wand having a valve attached thereto which is in fluid communication with a cleaning fluid supply. The sliding action of the dispenser aids in the connecting or disconnecting of the nozzle.

Claims

1. A surface cleaning vacuum nozzle or the like having:

a rigid body of hollow interior adapted for connection to a suction source;

an orifice in vacuum communication with said interior for engaging the surface and removing loose dirt or the like therefrom;

a cleaning materials dispenser adapted to be connected to a cleaning material supply for applying said cleaning material to the surface in close proximity to said orifice; and

attachment means for slidingly attaching said dispenser to said body, said attaching means comprising;

a. a projection formed on one of said body and said dispenser; and

b. a slot formed on the other of said body and said dispenser so that said projection is constrained within said slot to slide in a longitudinal direction with respect to said nozzle wherein said slot and said projection include means for holding said projection captive within said slot comprising;

a. a lug formed adjacent to one end of and at right angles to said slot; and

b. a deformable tab formed adjacent to one end of said projection such that when said projection is in sliding engagement with said slot, said deformable tab abuts said lug to limit relative sliding movement between said projection and said slot.

2. A surface cleaning vacuum nozzle as set forth in claim 1 wherein said deformable tab is sufficiently elastic so as to be deformed out of abutting contact with said lug and when released will assume its original position of said abutting contact.

3. A surface cleaning vacuum nozzle as set forth in claim 2 wherein said deformable tab and said lug each having an angled surface, said angled surfaces being formed such that when said dispenser is being assembled to said body said angled surfaces will engage whereby said deformable tab will be urged by camming action out of abutting contact with said lug.

4. An upholstery cleaning nozzle having:

a rigid body of hollow interior adapted for connection to a suction source, said body having an intake orifice in vacuum communication with said interior for engaging upholstery and removing dirt and debris therefrom;

a spray head assembly having a cleaning fluid connector means for attachment to a cleaning fluid source, and a dispensing spray member in fluid communication with said cleaning fluid connector means for applying the cleaning fluid to upholstery; and

attachment means for slidingly attaching said spray head assembly to said body comprising;

a. a dovetail-like shaped slot formed in said body;

b. a dovetail-like shaped projection formed in said spray head assembly adapted for sliding engagement with said dovetail-like shaped slot and constrained to slide in a longitudinal direction with respect to said upholstery cleaning nozzle;

c. means for holding said projection captive within said slot comprising;

a lug formed adjacent to one end of and at right angles to said slot and a deformable tab formed adjacent to one end of said projection so that when said projection and said slot are assembled said deformable tab abuts said lug to limit relative sliding movement between said projection and said slot wherein both said lug and said tab each have an angled surface, said angled surfaces being formed so that when said spray head assembly is being assembled to said body said angled surfaces will engage and said deformable tab will be urged by camming action out of abutting contact with said lug until said projection has sufficiently slidingly engaged said slot and said deformable tab being sufficiently elastic will assume its assembled position of said abutting contact.

5. An upholstery cleaning nozzle adapted for use in conjunction with a hot water extraction carpet cleaning system or the like, said cleaning nozzle having:

a. a body having a suction port formed in one end thereof and an intake orifice formed in another end thereof, said intake orifice being in vacuum communication with said suction port for engaging upholstery and removing dirt and debris therefrom;

b. a spray head assembly having a cleaning fluid connector portion for attachment to a cleaning fluid source wherein said spray head assembly is in fluid communication with said fluid source for dispensing cleaning fluid on the upholstery in proximity to said intake orifice; and

c. attachment means for slidingly attaching said spray head assembly to said body so that said suction port may be connected to said suction source independent of and prior to connecting said cleaning fluid connector portion to said cleaning fluid source, wherein said attachment means comprises;

a slot formed in said body, said slot having two spaced apart side surfaces converging in a direction away from said body;

a projection formed in said spray head assembly and adapted for sliding engagement with said slot, said projection having a flared surface arranged for interlocking engagement with one of said side surfaces.

6. An upholstery cleaning nozzle as set forth in claim 5 wherein said projection is constrained within said slot to slide in a longitudinal direction with respect to said upholstery cleaning nozzle.

7. An upholstery cleaning nozzle as set forth in claim 6 wherein said projection and said slot form dovetail-like mating surfaces.

8. An upholstery cleaning nozzle as set forth in claim 6 wherein said means for holding said spray head assembly captive to said body comprises:

a lug formed adjacent to one end of and at right angles to said slot and a deformable tab formed adjacent to one end of said projection so that when said projection and said slot are in sliding engagement said deformable tab abuts said lug to limit relative sliding movement between said projection and said slot.

9. An upholstery cleaning nozzle as set forth in claim 8 wherein said deformable tab is sufficiently elastic so that it may be deformed out of abutting contact with said lug and when released will return to its original position of abutting contact.

10. An upholstery cleaning nozzle as set forth in claim 9 wherein said deformable tab and said lug each have an angled surface, said angled surfaces being formed so that when said spray head assembly is being assembled to said body said angled surfaces will engage and said deformable tab will be urged by camming action out of abutting contact with said lug until said projection has sufficiently slidingly engaged said slot and said deformable tab being sufficiently elastic will assume its assembled position of said abutting contact.
