Definitions

the present invention relates to improvements made to housings with a rotary coupling for a vacuum cleaner nozzle.
a rotary connector housing for a vacuum cleaner nozzle generally has a top and a side wall, the rear part of which forms a body. This sleeve opening to the outside is intended to receive a tubing of a connector rigidly connected or articulated on a tubular handle of a vacuum cleaner.
the connection tubing is mounted to rotate about an anteroposterior axis and immobilized in translation in the sleeve.
the top of the housing forms a body with a substantially vertical internal conduit, communicating the aforementioned connection tubing with a window of a slip sole fitted and fixed under the housing, window which opens into a longitudinal channel suction from the sole.
the molding reveals marks due to shrinkage, marks which compromise the aesthetics.
the object of the present invention is to remedy these drawbacks: - by providing the necessary means to ensure a better flow of the gas flow and to reduce the risks of deposition of particles (dust, fibers, hair ...) in the nozzle and leakage outside, at the same time as these means allow easier molding, increase the rate injection and therefore reduce the cost price, eliminate apparent defects: shrinkage, injection point ...
the rear wall of the housing forms a body with a sleeve in which is rotatably mounted and immobilized in translation a connection tube to a vacuum cleaner, this housing comprising a substantially vertical internal duct which opens at the top in the sleeve and at the bottom in a window of a sole normally fixed under said housing, and, in accordance with the invention, the conduit has an upper bend connected to the molding with the sleeve and projecting into a bowl formed hollow in the top of the housing for the passage of the part of the mold which defines the external shape of said bend, which reduces the pressure losses and thus improves the flow of the gas flow,
the posterior and anterior walls of the conduit as well as the lateral walls of the latter are substantially vertical under the bottom of the bowl, while in the bowl above its bottom, the conduit is connected at the elbow by its substantially vertical front wall and by its converging side walls, the rear wall being integral with the sleeve.
the bowl is closed by a clip-on cover extending substantially the top of the housing.
a suction pipe 11 can be connected by its bent end 12 to a vacuum cleaner handle. Its free end 13 forms a tubular end piece which projects from a shoulder 14.
the end piece 13 has cylindrical bearing surfaces 15 to 17 intended to be fitted into the sleeve 5. Between the bearing surfaces 15 and 16 are provided annular sealing lips 18 and an axial immobilization groove 19 separates the bearing surfaces 16 and 17.
the conduit 6 has at its base a rectangular section connected to the sleeve 5 by a vertical rear wall 20, by a vertical front wall 21 extended by an upper bend 22 (Figure 1) and by vertical side walls 23 extended by converging walls 24 connected to elbow 22 (figure 2).
the duct 6 thus shaped connects the window 7 to the sleeve 5 with a progressive variation of the section and a guided deviation in the curve of the direction of flow.
This conduit 6 is integral with the top 2 of the housing via a parallelepipedal bowl 25.
the bottom 26 of the bowl is integral with the conduit 6, while the peripheral wall 27 of this bowl which is spaced from this conduit 6 is secured to the top 2 of the housing as well as to the upper half of the sleeve 5.
the peripheral wall 27 delimits in the top 2 an opening 28 through which a part of the mold can pass, defining the shape of the upper outer portion of the sleeve 5 and of the conduit 6 as well as the inner shape of the bowl 25. It provision is made to close the opening 28 by means of a cover 29 which is positioned in a recess in the top 2 and which can be fixed in a removable manner by means of flexible tongues with teeth 30 clipped into slots 31 in the bowl 25.
the cover 29 is integral with a lug 32 delimiting a semi-circular recess 33 whose diameter is substantially equal to the diameter of the bottom of the groove 19 of the end piece 13 of the tubing 11. Furthermore, a notch 34 is formed in the sleeve 5 and delimited by a sloping rear edge 36 which diverges upwards.
the tab 32 of the cover 29 placed enters the groove 19 of the 'end piece 13 and immobilizes, by abutment against the rear edge 37 of said groove, in translation said end piece without opposing its rotation.
the tab 32 is integral with inclined ramps 38 cooperating with the sloping rear edges 36 of the notches 34 of the sleeve 5.
the front edges 35 of the notches can be aligned with the front edge 37 of the groove 19 of the nozzle 13 when the latter is in place so that the lug 32 and its ramps 38 are perfectly wedged in said notches.
