Definitions

the present invention relates to a wire puller device for a vacuum cleaner nozzle sole.
Such a soleplate is fixed under a suction housing and has at least one longitudinal channel bordered by sliding lips. This channel opens freely to the outside through its underside and possibly its ends; it communicates through a median passage with a suction duct from the housing.
the sole is provided along at least one of its longitudinal edges which are substantially perpendicular to the direction of advancement of the nozzle of a gripping strip intended to hang the threads, pile or other caught in a carpet, a carpet. ..and detach them for suction then.
the gripping strip consists only of a velvet, bristling with suitably oriented hairs.
the flexible support of the bristles is treated to be self-adhesive and protected by silicone paper.
the pre-cut velvet band is peeled to remove the silicone paper and expose the adhesive, then it is glued to the bottom of an elongated housing recessed in the sole and extending in the middle area of the latter. ci along its front edge and / or its rear edge.
the housing (s) receiving a gripping strip may be located elsewhere.
the ends of its bristles must be at a specific distance from the sliding surface of the squeegee to hang the threads, bristles or the like. It follows from compliance with this condition that the strip itself is also urged to tear off by the substrate to be cleaned, which has the effect of tending to detach it from the sole.
the velvet of the gripping strip forms a body with a frame which gives it a certain nervousness.
This strip or plate is interchangeable after wear or fouling.
the strip or plate is not glued to the squeegee sole but is fixed there elastically. It is extended by lugs intended to be engaged in extreme slots in a housing of the sole. To assemble it, simply insert one of its legs into a slot by hand, bandage it to present its other tab opposite the other slot and release it so that, by elastic return, this other tab enters this other slot and the strip or plate is pressed against the bottom of the housing.
German Utility Model No ⁇ 7,237,505 the pile is advantageously fixed on a flexible plastic strip which gives this "sandwich” a nerve useful for installation as described in the foregoing.
This Utility Model aims to obtain a "polarization" of the wafer during installation so that its bristles are always properly oriented relative to the suction channel of the squeegee sole.
the end tabs have different widths corresponding to the length of the slots.
French Patent ⁇ 2,350,819 discloses a son picker device for vacuum cleaner nozzle which is also composite, the strip having a oriented pile velvet attached to a plastic substrate and having end flaps of unsymmetrical "keying" likely to be engaged in slots in the sole.
This strip is not glued to said sole; it is removable and holds in place thanks to its “nerve”.
the slots in the sole housings make it possible to position composite gripping strips on the sole of the squeegee which, by virtue of their nerve, press against the bottom of the housings.
These bands are not glued to the nozzle sole to be interchangeable and the function of the slots in the housings of said sole have a very specific function.
the object of the present invention is to remedy the aforementioned major drawback of the squeegee soles with glued gripping strips, a drawback which resides, in use, in the tendency to detachment; it then proposes to apply the aforementioned slots for interchangeable bands, but by giving them an essentially different function. Concomitantly, it aims automation of the installation of Velcro straps for the sole purpose that the cost of manufacturing is rather lowered.
the wire puller device for the vacuum cleaner shoe sole comprises, as is well known, at least one gripping strip bristling with bristles, this strip being glued to the bottom of at least one elongated housing which has hollow the sole, and in accordance with the invention, the strip consists only of a flexible velvet intended to be glued directly to the bottom of the housing and, to avoid detachment, the ends of said strip are engaged in transverse slots located near the ends of the housing and protrude inside.
the transverse slots of the housing are spaced from the ends of the latter, the length of this housing being at least equal to that of the strip.
the invention also extends to a tool for installing such glued velvet. It comprises, on the one hand, a pressure shoe intended to apply said pre-glued strip against the bottom of the aforementioned corresponding housing and, on the other hand, two threading blades forming one body, spaced apart from the distance of the geometic axes of the slots of this housing opposite which they are located, each having a thickness at most equal to the difference between the thickness of a slot and twice the thickness of the strip and movable perpendicular to said housing.
the blades are connected together to a positive actuating member, while the pressing pad is connected to said member by means of at least one elastic member, such as a spring.
the vacuum cleaner nozzle comprises a casing 1 of molded plastic material in which a movable plate 2 carrying a peripheral brush 3 is guided in vertical translation between a high neutralization position and a low projecting position d for brushing.
the housing 1 is closed by a sole 4 fixed to it by means of screws 5.
gripping bands 13 and 14 are provided in anterior 15 and posterior housings 16.
the transverse edges 17 of the housings are less protruding than the lips 6 and 7.
Each strip is a velvet comprising a flexible substrate 18 integrating with the bases of hair-pulling hairs 19.
the depth "p" of each of the housings 15 and 16 in the anteroposterior direction is determined so that, taking into account of the overall thickness of the substrate 17 and of a layer of glue 20 deposited between the latter and the bottom of the housing in question, the bristles 19 sufficiently protrude from the edges 17.
slots 21 and 22 are cut in the ends of each of the housings 15 and 16.
the corresponding gripping strip 13 or 14 has a length "l" greater than the distance "d" slots 21 and 22.
the ends 23 and 24 of the strip in question pass through the slots 21 and 22 and project under the inner face of the sole, then of the intermediate part 25 of said strip forms a body, thanks to the layer of adhesive 20, with the bottom of the corresponding housing 15 or 16.
the distance D of the slots 21 and 22 is less than the length L of the corresponding housing 15 or 16 which is itself at least equal to the length 1 of the conjugate strip 13 or 14.
each strip is laid flat on the bottom of the corresponding housing and is automatically centered thanks to the slope of the ends thereof.
It comprises a pressure shoe 26 extending, during installation, opposite the intermediate part 25 of the strip 13 or 14, that is to say of the part of the bottom of the housing 15 or 16 located between the slots 21 and 22. It also comprises two threading blades 27 and 28 forming a body therebetween and arranged on either side of the shoe 26, opposite said slots into which they are intended to penetrate.
the thickness "e” of each of the blades 27, 28 is at most equal to the difference between the thickness "E” of the corresponding slot 21 or 22 and double the thickness "e '" of the velvet.
the threading blades 27 and 28 are connected by a cross member 29 secured to a positive actuating member, not shown, such as the piston of a jack; the shoe 26 is guided in translation in the same direction as the blades 27 and 28 and it is subject to at least one spring 30 bearing under the cross member 29.
the pads 26 press these on the bottoms of the housings, then the blades 27 and 28 continue the approach by compressing the springs 30 and penetrating into the slots 21 and 22 to tension said bands, conform their U-shaped ends and release these on the other side of the sole.
