Vacuum Cleaner Nozzle Provided With A Pivot Blocking Device

Abstract

A vacuum cleaner nozzle includes a main body having a suction mouth; a connecting sleeve fluidly connected to the suction mouth; a hinge device mechanically connecting the connecting sleeve to the main body and configured to allow a tilting of the connecting sleeve forwards and backwards and about a first pivot axis and a tilting of the connecting sleeve leftwards and rightwards and about a second pivot axis; and a pivot blocking device configured to block a pivoting of the connecting sleeve about the second pivot axis at least when the connecting sleeve occupies a predetermined sleeve position.

1 . A vacuum cleaner nozzle comprising:
 a main body including a sole provided with a lower face configured to be oriented towards a surface to be cleaned, and a suction mouth emerging into the lower face of the sole,   a connecting sleeve to which a suction tube of a vacuum cleaner is configured to be fastened, the connecting sleeve being fluidly connected to the suction mouth,   a hinge device mechanically and hingedly connecting the connecting sleeve to the main body, the hinge device comprising a first pivot connection defining a first pivot axis extending transversely to a main movement direction of the vacuum cleaner nozzle and configured to allow a tilting of the connecting sleeve forwards and backwards relative to the main body and about the first pivot axis, and comprising a second pivot connection defining a second pivot axis and configured to allow a tilting of the connecting sleeve leftwards and rightwards relative to the main body and about the second pivot axis,   wherein the vacuum cleaner nozzle includes a pivot blocking device provided in a rear part of the main body, the pivot blocking device including a blocking part partly delimiting a blocking area and configured to block a pivoting of the connecting sleeve about the second pivot axis at least when the connecting sleeve occupies a predetermined sleeve position in which, when the vacuum cleaner nozzle rests on a horizontal surface, a central longitudinal axis of the connecting sleeve extends substantially horizontally.   
     
     
         2 . The vacuum cleaner nozzle according to  claim 1 , wherein the blocking part and the connecting sleeve are configured such that, when the connecting sleeve occupies the predetermined sleeve position, the central longitudinal axis of the connecting sleeve is located in the median longitudinal plane of the vacuum cleaner nozzle. 
     
     
         3 . The vacuum cleaner nozzle according to  claim 1 , wherein the connecting sleeve includes an abutment part configured to cooperate with the blocking part when the connecting sleeve occupies the predetermined sleeve position, so as to prevent a pivoting of the connecting sleeve about the second pivot axis. 
     
     
         4 . The vacuum cleaner nozzle according to  claim 1 , wherein the pivot blocking device includes a guide part configured to guide the connecting sleeve towards the blocking area when the connecting sleeve is pivoted backwards and towards the predetermined sleeve position. 
     
     
         5 . The vacuum cleaner nozzle according to  claim 4 , wherein, when the central longitudinal axis of the connecting sleeve is inclined laterally relative to the median longitudinal plane of the vacuum cleaner nozzle and the connecting sleeve is pivoted backwards and towards the predetermined sleeve position, the guide part is configured to cooperate with the connecting sleeve so as to pivot it about the second pivot axis and towards the median longitudinal plane of the vacuum cleaner nozzle. 
     
     
         6 . The vacuum cleaner nozzle according to  claim 4 , wherein the guide part has a general V shape. 
     
     
         7 . The vacuum cleaner nozzle according to  claim 4 , wherein the guide part includes a first guide surface and a second guide surface disposed on either side of the median longitudinal plane of the vacuum cleaner nozzle, the first and second guide surfaces converging towards the blocking part. 
     
     
         8 . The vacuum cleaner nozzle according to  claim 1 , wherein the blocking part includes a first blocking surface and a second blocking surface which are disposed on either side of the median longitudinal plane of the vacuum cleaner nozzle and which extend substantially vertically when the vacuum cleaner nozzle rests on a horizontal surface. 
     
     
         9 . The vacuum cleaner nozzle according to  claim 3 , wherein the first and second blocking surfaces are spaced apart from each other by a spacing distance corresponding substantially to the width of the abutment part. 
     
     
         10 . The vacuum cleaner nozzle according to  claim 8 , wherein the guide part includes a first guide surface and a second guide surface disposed on either side of the median longitudinal plane of the vacuum cleaner nozzle, the first and second guide surfaces converging towards the blocking part, and wherein the pivot blocking device includes a first lateral wall and a second lateral wall located on either side of the median longitudinal plane, the first lateral wall including the first blocking surface and the first guide surface, and the second lateral wall including the second blocking surface and the second guide surface. 
     
     
         11 . The vacuum cleaner nozzle according to  claim 1 , wherein the hinge device includes a connecting member hingedly mounted on the main body through the first pivot connection, the connecting sleeve being hingedly mounted on the connecting member through the second pivot connection. 
     
     
         12 . The vacuum cleaner nozzle according to  claim 1 , wherein the main body includes an upper cover fastened to the sole and configured to cover at least partly the sole, the pivot blocking device being provided on the upper cover. 
     
     
         13 . The vacuum cleaner nozzle according to  claim 1 , which includes a rear anti-tilt abutment provided on the main body, the rear anti-tilt abutment being located behind the suction mouth and at least partly behind the first pivot axis. 
     
     
         14 . The vacuum cleaner nozzle according to  claim 13 , wherein the rear anti-tilt abutment is deformable.
