Description

The invention relates to a suction attachment for damp cleaning of surfaces, especially vertical ones Surfaces, with a liquid application device.

Cleaning devices for wet cleaning of surfaces, esp special of vertical window surfaces, are in one Variety of variations known. They exist for the time being from a suction device, which next to a suction device tion also via a storage container for cleaning liquid has. The Reini is pressurized supply liquid from the suction device via a Drucklei tion supplied to the actual cleaning device attachment and there over nozzles, brushes, sponges or the like applied to the surface to be cleaned. The opened gene liquid is then from the suction device via a often slit-shaped suction mouth and the attached to it closing suction channel sucked up again. Such Cleaning devices are mostly designed as industrial devices sets and accordingly voluminous and expensive and for not suitable for normal household use.

A cleaning device is known from EP 0 243 323, in which a liquid application device with a cleaning liquid or a cleaning there steam is supplied via a pressure line. For the order the cleaning liquid to the one to be cleaned The area is the liquid application device there provided with a sponge that is inside a suction bell housing around a surface to be cleaned parallel axis pivoted into a working position is arranged. Parallel to the length of the sponge or its axis and thus perpendicular to the usual work direction is still a slit-shaped suction mouth  above the surface to be cleaned, with a sealing lip pe just sitting on it. Suction Bell housing and suction mouth are with a suction channel in which the Drucklei device for the supply of the cleaning liquid is arranged. Cleaning device attachment and cleaning functionally form a unit and cannot be used in isolation from each other. In the - not prepublished - WO 96/01614 is a Suction device attachment for wet cleaning of surfaces wrote, which as preferred also in the sense of this Invention as a front attachment of pure suction devices, e.g. household suction devices are also used. It is there as here important that a pressure line from the suction device to the liquid application device can be omitted and the suction device alone on the poss suction facility, i.e. no tank system and pressure system especially for the cleaning liquid contains. For this purpose, the liquid on Carrying device of the suction device attachment described provided with its own cleaning liquid tank, a separate supply line for the cleaning liquid can be omitted. Furthermore, a Lagever adjustability of the liquid application device ge shows what the liquid application device with an annular connecting element, the suction channel encompasses the housing and on it axially against the force an exposed one, the suction duct housing as well enclosing spring is guided. Such an open Leading is with regard to pollution vulnerable and also has good accessibility risk of injury.

In the suction channel of this suction device attachment is also a moisture-absorbing filter provided, which  the extracted liquid-air mixture moisture deprives and saves. It is one by this characteristic Another constructive measure of fundamental importance tion when using household vacuum cleaners light, namely the phase separation of the extracted river liquid-air mixture. This is when using usual household vacuum cleaners due to their electri construction and suction technology out of safety safety reasons necessary. Such a filter effect based phase separation is however a common one Suction technology also due to the large pressure that occurs losses in principle on the filter. In particular the other, if another, for the gaseous phase permeable membrane is still provided, which the rivers phase when the absorption capacity of the the liquid phase storing filter material then escaping liquid still keeps.

Therefore, the technical problem arises Suction device attachment for wet cleaning of surfaces by hand safe and secure, especially for one To use with common household vacuum cleaners ten.

This technical problem is caused by the secondary independent, independent main claims for themselves and especially solved in their combination. It poses the claim 1 on a suction device attachment, in which the liquid application device against a separately trained suction channel housing is adjustable, in which ends in a slit-shaped suction mouth fender suction channel is arranged, the suction channel housing the liquid application device arcuate is arranged overlapping and inside the arch Liquid application device on at least one  Slider is caught, which is the suction channel housing interspersed and on the top of the suction duct housing as Handle is designed to adjust the position. Info ge of these design features is first of all the rivers liquid application device arc-shaped - at least in part wise - from the housing of the suction channel, which geson changed from the liquid application device det is covered and thus also protected. It is but through the separate design of the suction channel housing ses and the liquid application device the latter an essentially independent component, which is easy For example, replaced or separated from the housing can to cleaning cloths, bristles or the like e.g. to replace. Inside the arch, d. H. regarding a position of use between the surface to be cleaned and which cover the liquid application device the suction channel, is the liquid application device caught on at least one slider. It may be a detachable connection or is the slide itself detachable from the suction duct housing which it passes through around the top of the suction housing as a handle for adjusting len able to be trained. The mentioned at the beginning different positions of use of the liquid application device are accordingly no longer an actuation on the side of the suction attachment ordered knobs or the like according to EP 0 243 323 set, which is particularly in a Window frames or a corner as extremely annoying sen. Handling and security are also against above the suction device described in WO 96/01614 resolution significantly improved.

In the case of household suction devices, in particular, the stung also limited. Long suction channels, e.g. in shape of hoses and, if necessary, filter devices  further flow resistances represent the suction power reduce even further. It can extract power a suction device attachment with respect to one surface to be cleaned applied cleaning liquid due to the independent combination of features of the Claim 2, in particular also in connection with the Features of claim 1, are improved if is based on the fact that the suction mouth is transverse to their longitudinal extension into individual suction sections is divided, which in the suction direction in a common Men suction chamber, on which preferably several Intake manifold branches are connected, which continue in Extraction direction to a common suction channel cross cut are summarized. This measure will an even speed profile of entry speed reached in the suction mouth. Add to that likewise in that by several at the common Suction chamber connected intake manifold branches uniform vacuum is produced there. In The suction pipe is behind the suction direction branches to a common suction channel cross section a suction channel summarized, which ultimately in the suction device ends. Improving the suction performance also serves the measure that the suction mun inner wall directly and continuously in a sealing lip merges. Usually these are Sealing lips that prevent the applied Reini serve liquid, in a U-shaped groove of the Suction channel housing bordered. This creates in the Wall a crack, on which there is under circumstances a jam of the withdrawn water during suction can. The suction speed is still ge increases the outer cross-sectional area of the Saugmün a suction nozzle with a width of less than 5 mm, preferably less than 2 mm  opposite a subsequent suction section, wherein in Suction direction the length of the suction nozzle about its width corresponds. On the one hand, this measure includes a trop open the suction mouth after switching off the suction device set or suction device largely from one Precipitation of the aspirated liquid in the area For example, the common suction chamber itself Liquid in the area of this cross-sectional change will collect. Leakage of fluid through the Suction nozzle of such a small width already appears by the surface tension of a drop of water as almost impossible. On the other hand, it also only very small solids with sucked up, so that it is entitled to use an absorbed liquid Air mixture just to speak.

As already mentioned, a change in position is the Liquid application device provided, for example an inactive location with only one peel and / or Suction function of the suction device attachment without liquid application in a position of use with suction the applied cleaning liquid and a wide one ren position, in which only cleaning liquid is applied and suction and / or peeling not happened. For such a change of position is in A guide is arranged inside the arch, in which the rivers liquid application device, slide-controlled linear is movable. Despite the arched overlap the liquid application device by in particular a specially designed suction channel housing becomes one linear displaceability is preferred because of this It's easy to train leadership. It is preferred that - with reference to a system of the suction attachment in use position on a surface to be cleaned - the Displacement of the liquid application device  an inactive withdrawn behind the suction mouth Position by the force of a spring in a medium ar beitslage in which the liquid application device free of the slide against the force of the Spring is movable, and from the slide controlled the Liquid application device in one of the suction mouth protruding position can be brought in which they are over move the slide against the suction duct housing direction is supported. Two sliders can be used Relative to the preferred direction of work the ends of the liquid application device hen. However, central training is preferred only a single slide, which then the Saugka nalgehäuse penetrated approximately in the middle, then the shooting About and, if necessary, the guide between manifold branches are arranged. This does not make the suction channel itself enforced and ent sealing problems or the like fall.

To the suction device attachment for wet cleaning of surfaces chen, especially of vertical surfaces, with a Liquid application device and one in a suction mouth leaking suction channel through which the suction a liquid-air mixture gets off the surface sucks, especially for household suction devices To make bar is one between the suction mouth and the Saugge advises arranged phase separation device in which the Liquid-air mixture by centrifugal forces a flow deflection into a liquid and a gaseous phase are separated, still provided. Due to this separation, the suction device itself does not suck Liquid. Electrical or suction problems me regarding suction of liquids do not work with it. The security concept continues The measure takes into account behind any  Phase separator a safety valve in suction direction to be provided, namely one in the suction direction gushing water behind the phase separator serventil, which with insufficient phase separation closes the cross section of the suction channel. Usual, modern household vacuum cleaners are with overload protection provided today so that the closing of the Suction channel causes no problems, but a lot the suction devices even when larger liquids appear quantities that determine the capacity of the phase separation device overwhelming direction, reliably before penetration is protected from liquids. In development provided that in the phase separator separated liquid in a tank outside the Suction channel is collected. This will make a cross cut narrowing of the suction channel avoided thus flow losses in the suction channel are also low This feature also has the advantage that if there is a leak in the tank liquid into the suction channel itself does not occur. After a preferred training manure is provided that the tank operationally releasable is connected to the suction device attachment. Independent of the spatial arrangement and attachment to one load-bearing element of the suction attachment is the Possibility given a full tank quickly to be replaced by an empty one or the filled tank to empty and then reinsert, especially in also insert the suction attachment. Such Measure facilitates the handling of the invention ß suction device attachment considerably. In development can then be provided that the tank is annular designed the suction channel and / or encloses and / or an outer wall of the suction device attachment too trains. This makes geometrical arrangements found which a balanced with a small footprint  gene and largely symmetrical design of the Saugge allow council resolution. After another measure it is envisaged that the tank will be a disposable cartridge forms is. This is particularly advantageous if it is further provided that the tank with a liquid absorbent material, an absorbent, is filled. It is then a sloshing back and forth a quantity of liquid inside the tank closed. As a result of the latter measure then also with the tank inflow by a wrong one Handling the vacuum attachment no liquid emerge and if necessary into the further suction channel reach. In particular, it can then also be provided be that the tank in the suction direction behind the tank inflow of the separated liquid with the suction channel is connected via an intake duct. This is the one art created that without a liquid through this enters the suction channel, for example by insertion liquid absorbent material into the tank, a negative pressure is generated in it, which the Phase separation supported. Likewise, through this measure also a leak from the tank inflow prevented.

The centrifugal responsible for phase separation Forces become regular through a flow deflection caused, for example by baffle walls a substantially Z-shaped flow inside half of the suction channel. In the area of distractions can then the tank supply of the separated liquid For example, be provided, namely where the deflecting dius is the narrowest. However, it is preferred that the Centrifugal forces caused by vortex formation in the liquid air / air mixture. This means, that the flow of the extracted mixture into a rota  tion is transferred. In connection with the movement in Suction direction will then be helical Bahnli training on which particles move. Info Here, the centrifugal forces move heavier Particles, namely entrained water droplets, ver dirt or the like from the outer circumference and can be separated from the gaseous phase there will. Such a rotatory component of the Strö mung can in a swirl duct section of the suction duct be generated. This is done in the swirl channel section of essentially rotationally symmetrical and in particular their round cross section preferably tangential introduced the flow of the liquid-air mixture. Due to the vacuum on the suction device side, inner half of the swirl channel section this flow too another component in the suction direction, but retains nevertheless the rotary component of the movement of the Liquid-air mixture. Such phase separation Directions are in technology to so-called cyclones have been further educated, which here also for Can come into play.

Regarding the separation of liquid and gaseous Phase is further suggested that the vortex formation by arranged on the outside on a flow body Guide vanes is achieved. One is preferred here Design in which the flow body is semi-spherical is gel or mushroom-shaped, the verrun dete surface of the general flow direction is sufficient. The rounded head in particular has one reduced diameter compared to the flow channel on. The resulting annulus becomes partial interrupted by the outside on the head area of the flow body arranged guide vanes. Last one re cause a radial acceleration of the impact  the liquid-air mixture. These vanes are radially aligned in one embodiment. It he also proves to be advantageous that a through walking, helical guide vane is. This winds around the flow body and is more preferably combined with this material the. Also through this helical guide vane becomes a radial acceleration of the impinging Liquid-air mixture causes. In an advantageous Further training of the subject of the invention is proposed hit the vane radially with an inside wall of the suction channel closes. So it is provided that regardless of the design of the guide vanes at least the radial support of the flow body effect in the flow channel, thus causing further commands fixations and means for the correct fixation of the Flow body in the flow channel who waived that can. When arranging a continuous, screw aisle-shaped guide vane is further provided that two courses are formed. With this configuration the vane of the flow body resembles one two-start screw thread. Next will be featured suggest that the flow body has radial breakthroughs has, for the passage of the gaseous phase. For this is the preferably rotationally symmetrical flow body executed hollow, with suction from the Inside is done. The radial openings are mün the roughly transverse to the axis direction. By using Swirl, to achieve radial acceleration forces, and hard flow deflections in the radial area breakthroughs to achieve inertia forces, the liquid phase is separated from the gaseous. It is further proposed that the passage the gaseous phase from the outside of the flow body is made radially inward. Due to the  radial acceleration is the liquid phase over the Radial openings in a radially outer Forwarded annulus. One is preferred here Design in which the radial openings in Flow direction arranged behind the guide vanes are. In this regard, it can also be provided that the Axial area behind the guide shovel is slightly smaller in diameter against above the rounded Be realm of the flow body. In the transition area between are these two flow body sections the radial openings arranged. To also residual moisture te, so-called atomized liquid drops, from which To separate gaseous phase, it is provided that the Flow body on the inside in an area in flow direction at least before the radial openings partly with a liquid absorbent material is filled. This material, e.g. a foam, is in an undercut in the interior of the stream arranged body. Through the hard flow reversal in the area of the radial openings Airflow inside the flow body initially counter deflected towards the general flow direction. Of the rounded head region of the flow body causes then again a reversal in the usual flow direction. In this reversal area it is liquid absorbent material arranged to the gaseous Phase to remove any residual moisture. Is further provided that the flow body in the direction of flow device is arranged in front of the tank. The separated rivers sige phase is on the outer surface of the flow body over the radial openings in Strö direction transported in order to subsequently in the Flow body following tank to be collected. Around the transition between flow body and tank  Separation of liquid and gaseous phase short circuit To make it safe, it is intended that the flow body spring-supported against an end face of the Tanks is charged. Tank and flow body can thus be formed in two parts, making the possible There is a possibility of designing the tank to be exchangeable. The tank is preferred as a liquid absorbent Material formed, for example in the form of a separator sponged.

For the separation itself it can also be provided that a liquid-air mixture with a rotary Movement component in the suction channel on a cross cut of the suction channel almost filling, funnel-shaped moderate constriction within which the gaseous Phase is forwarded and over the edge of the rivers phase is separated and from there, for example, into the derived at the beginning of the ring-shaped tank becomes. Due to the centrifugal force, the heavier water droplets, entrained particles or the like on the outer edge of the flow cross-section tes essentially and from there over the edge derived from the funnel-shaped narrowing on the outside. The Dimension of the funnel-shaped narrowing is given on the stop operating conditions, d. H. e.g. on the Diameter of the suction channel, the flow rate speed, the proportion of the liquid phase in the liquid speed-air mixture and the like. Have in practice there are free areas between the funnel-shaped Narrowing and the wall of the suction channel in the range of proved to be usable within a few millimeters.

In a further embodiment, in particular after a Phase separator still has a splash valve provided that preferably one transverse to the flow direction  device arranged within the suction channel About has in the direction of flow against the force a spring the cross section of the suction channel when it hits closed by splash water. With such a The arrangement affects the amount of liquid and Suction vacuum in a common direction on the Slider, which also ensures secure closing is steady. The spring can be used as a tension or compression which is designed and is accordingly upstream or downstream of the flow direction on the slide to arrange attacking. Shooting is more preferred Guided in a tube section in a ring and pas the gaseous phase causes the slide to move radially external openings. These can be simple when closing the slide against an annular shoulder hit and be closed or radial outside of one through the ring shoulder in cross section reduced suction channel. Next is a tank preferred, the one with increasing moisture its volume increasing absorbent is filled by the volume increase of the splash valve is closed. This can be done by a simple Tappet or lever mechanism, for example run directly by moving a wall of the tank against the spool of a splash water valve meets. In particular, in the case of an annular tank education an axial volume increase only see that on the slider of the splash valve acts in such a way and only then that when exhausted of the absorbency of the slider Splash water valve is closed. This slider can be plate-shaped, for example, formed transversely in the stream tion of the normally gaseous phase lie. Likewise, such slides are spherical miger shape already known, for example  so-called industrial vacuum cleaning gladly.

Next is a vacuum cleaner for wet cleaning of surfaces, especially vertical surfaces with a liquid application device and a Reini gungstuch, the cleaning cloth over the liquid keitsappvorrichtung is excited and by this is wetted on the back, provided that the cleaning cloth has frame cheeks on the edge, for positive locking attachment to the liquid application device. The attachment of cleaning cloths to a holder tion is usually a detachable connection to one Exchange of the cleaning cloth in case of wear or Allow pollution. For fastening the Reini cloth have different shape or strength conclusive variants. It is known here, for example, that Cleaning cloth edge with clips or a Velcro to fasten the band connection. There are also connections known in which a hooking of the cleaning door ches by means of bristles, for example scrubbing. It also belongs to the state of the art a connection through sewn pockets, in which Immerse appropriate tabs. A disadvantage of this On the one hand, solutions is the relatively large space requirement for the fasteners. Next are these connections only achieved through cumbersome handling bar, with the result of a possibly inaccurate Positioning the cleaning cloth. With an apprenticeship with sewn-on pockets or the like a complex, costly sewing job. The Solution according to the invention is an inexpensive, simple fast and easy attachment for a Reini cloth. The attachment is structurally small, light and self-explanatory at the same time. This is a Reini  cloth change with one hand, the second hand holds the suction device attachment. It is featured beat the edge side frame cheeks as thickenings to be trained on the cleaning cloth. For this purpose, that the frame cheeks are keder-like. The The cleaning cloth is cut to size after cutting preferred measure preferably on two longitudinal edges with one Keder-like thickening. Next is featured hit the frame cheeks on the cleaning cloth are attached. These can be injection molded or be glued. However, training is preferred where the frame cheeks from the cleaning cloth are shaped. An otherwise usual flanging or Ver linking of the cleaning cloth is not necessary. This can further be provided that the cleaning cloth with is encapsulated in a plastic jacket, the manufacturer can be done fully automatically. As special before This training proves to be partial when used same or similar materials, as this entire cleaning cloth is recyclable. For befe cleaning cloth on the liquid Carrying device is the cloth on the pressure surface the liquid application device placed or ge tense. The keder-like thickenings are afterwards in appropriately trained areas of the device e.g. clipped in. So it is suggested that the rivers liquid application device groove-like recesses owns, to accommodate the frame cheeks. These extend preferably perpendicular to a normal machining direction of the device, the application or Wetting surface. As a handling advantage it turns out that the groove-like recesses are undercut. This is to simplify the hand availability. The piping-like thickenings are per Finger pressure in the recesses or  

Grooves pressed in. Alternatively, it can also be provided be that the recesses with resiliently evasive Cams are provided for the positive reception of the Frame cheeks. These cams are preferably even distributed over the entire length of the groove-like recess The keder-shaped thickening becomes compliant designed, the attachment can also be frictionally be designed. In an advantageous development extension of the subject matter of the invention it is provided that groove-like recess at right angles along its length has sections offset along its longitudinal axis such that a frame cheek alternately in sections on the one or the other side surface of the groove-like recess applies. This makes it simple, safe Possibility of fastening one with a frame cheek in Form of a cleaning cloth provided with a piping strip given. The attachment takes place without moving or additional parts in the simplest way by inserting in a lengthwise groove for the frame wall ge or keder strip. The latter is used for assembly, for example with slight deformation zigzag in the with the offset sections provided groove-like recess indented. When inserted, the Frame cheek straight along its length. For this purpose, the staggered sections of the groove-like recess in alignment with each other me for the frame cheek. These are on the opening side Sections with mutual, the recording rooms part wise overlapping, strip-like projections hen, which after pressing in the frame cheek of this are under attack. So the cleaning cloth is in the Area of the frame cheek or the welt strip securely in the groove-like recess held. The groove-like The recess has no moving parts, which means that Cleaning device designed in this area massive  can be. The frame cheek or the welt strip, which are both sewn and on the cleaning cloth can be sewn, welded or injection molded here as a spring for the reversible arrangement of the Reini used on the cleaning device. That feather is therefore on an exchange part, namely on the Reini cloth, attached. In exchange of the cleaning door Accordingly, according to the invention, the spring element is also used exchanged. The clamping force is almost still big adjustable through the dimensions of the groove-like recess It is also conceivable to use the cleaning cloth of your frame cheek laterally into the one with the offset To insert sections provided, groove-like recess ben, with the individual sections formed in this way are that the frame cheek is in a slight waves shape alternately on one and the other side surface supported on the offset sections. Hereby a clamping effect is also achieved. It will further suggested that over the length of the groove-like Recess six to ten of the offset sections are trained. To disassemble the cleaning door To simplify ches, it is proposed that assigned net to the groove-like recess a finger behind handle opening is provided. By means of this can the frame cheek or the piping strip of the cleaning door ches are gripped, after which by the resilient Ausge design of the frame cheek in the simplest way can be pulled out through the slot opening. Erfin According to the invention it is provided that the finger grip Opening with penetration of a side wall of the suction cup councilor is trained. Here, an endbe range of the frame cheek for dismantling the cleaning door ches gripped, preferably training selected in which the finger grip opening is one small length range of the groove-like recess fully  constantly replaced in such a way that a subsection of a Full frame cheek in the finger grip opening dig exposed. Finally, it turns out to be special advantageous that the cleaning cloth spat twice is formed symmetrically. The cleaning cloth can because of that in up to four different positions attached to the liquid application device the so that the dirt holding capacity is fully exhausted can be used.

Fig. 1 shows a suction attachment 1 in a longitudinal section perpendicular to a surface to be cleaned 2 , with a liquid application device 3 in a fe supported supporting position.

The liquid application device 3 has its own tank 4 for a cleaning liquid, not shown. This measure makes it possible to dispense with a pressure supply line for the cleaning fluid from a suction device. This creates one of the basic requirements for using the suction device attachment 1 in connection with conventional household vacuum cleaners, for example. A capillary device, here a row of bristles 5 , which protrudes into the tank 4 and is supported on a cross plate 6 , ensures, by the capillary effect, that the cleaning liquid emerges slowly, evenly onto the surface to be cleaned 2 . The row of bristles 5 is, for example, set at an angle of approximately 45 ° with respect to the surface 2 to be cleaned, as a result of which such a row of bristles 5 also has a good mechanical cleaning effect comparable to a scraping. After exiting from the capillaries formed between the individual bristles, the cleaning liquid wets the back of a cleaning cloth 7 arranged over the bristle row 5 , which is perpendicular to the usual direction of work, represented by the double arrow 8 , is clamped at the edges in sockets 9 of the liquid application device 3 . For this purpose, the cleaning cloth 7 , for example. A micro fleece, even edge side, in particular at the edges transversely to the working direction 8 , connected to frame cheeks 16 here of round cross-section. The frame cheeks 16 are clipped into undercut recesses 17 of the housing of the liquid-carrying device 3 .

The liquid application device 3 is displaceable in the double arrow direction 10 in the working position shown in FIG. 1 against the force of a spring 11 , which is formed here as a compression spring on a pin 12 . At the other end, the spring 11 is supported on a pin 13 on a holding plate 14 of a suction channel housing 15 .

Within the suction channel housing 15 , a suction channel 20 is arranged, with here as the suction channel 20 also the total derivative of a liquid-air mixture sucked off from the surface 2 to be cleaned from a suction nozzle 21 to a suction hose 22 to a suction device, not shown here, For example, a usual household vacuum cleaner is understood.

The suction mouth 21 is, as shown in FIG. 1, substantially in the form of a slot and parallel in its overall extent ung to the liquid application device 3 , ie, essentially transversely to the usual working direction 8th

The suction channel housing 15 that receives the suction channel 20 in the slot-shaped suction mouth 21 covers the liquid application device 3 in an arc shape over an angle of approximately 70 °. In the edge areas transversely to the working direction 8 , an overlap can also take place through the suction channel housing 15 , but these areas preferably remain free of overlap and can be brought into contact with, for example, a window frame or the like with cleaning surfaces perpendicular to the surface 2 .

Within the sheet the Flüssigkeitsauftragsvor is direction captured on a centrally formed here slider 25 3 which passes through the suction channel 15 and the top side of the Saugkanalgehäuses 15 as handle 26 for adjusting the position of the liquid application apparatus 3 according to the Fig. 4, 6, 9 are formed. The slide 25 is essentially strip-shaped and has a bend 27 of 180 °, so that the handle 26 can be pressed down in the manner of a protruding leaf spring. By depressing a Rie gel 28 is brought from the locked position shown in Fig. 1 in a middle of three recesses 29 and is then within a slot 30 in the Saugkanalgehäu se 15 displaceable. By engaging the bolt 28 in one of the recesses 29 , three slider positions can be secured in place.

FIG. 4 shows the handle 26 in a retracted position in a section offset from FIG. 1 in the area of the suction mouth 21 . Here, the liquid application device 3 is brought into a retracted position behind the suction mouth 21 , inactive position against the force of the spring 11 via the slide 25 . In this inactive position, the suction mouth 21 is single with a sealing lip 31 on the surface 2 to be cleaned and can be removed and / or sucked up by means of the sealing lip 31 carried cleaning liquid, for example. However, there is no application of cleaning liquid.

In order to be able to fix the liquid application device 3 in the inactive position shown in FIG. 4 against the force of the spring 11 on the suction channel housing 15 , the slide 25 on the part of the liquid application device 3 has a driver 32 of round cross-section here, which extends transversely to the working direction 8 extends, cf. Fig. 5. The driver 32 is caught in a guide recess 33 and there otherwise freely movable Lich, see. also FIGS. 6 and 7.

In the inactive position shown in FIG. 4 and 5 is the driver 32 at a bounding surface 34 of the guide recess 33 and prevents its hard Stel lung by the latch 28 in the rear recess 29 a movement of the liquid application apparatus 3, in which the slide 25, this against the Saugkanalge housing 15 holds.

By pushing down the handle 26 , the latching fit of the latch 38 in the rear recess 29 is released and the slide 25 can be displaced towards the central recess 29 . In this way, the driver 32 are the boundary surface 34 is free and the force of the relaxing spring 11, the Flüssigkeitsauftragsvor device 3 in a middle working position according to FIG. 1 and FIG. 6 and 7 housed. It is now the driver 32 approximately centrally within the guide recess 33 , whereby a resilient movement of the liquid application device 3 is made possible in the double arrow direction 10 , which is limited by the boundary surfaces 34 , 35 . The displacement of the slider 25 can be performed, for which purpose lateral, not shown te guide sections of the slider 25 in corresponding grooves 36 of the suction duct housing 15 who performed the.

Furthermore, guides 37 , 38 are also provided in the interior of the arch for a slide-controlled linear displaceability of the liquid application device 3 . The Füh tion 37 consists of an extension piece 39 of the liquid application device 3 , which ends in a sliding part 40 of round cross-section, which is linearly slidable ver in a guide channel 44 of the suction channel housing 15 . Such guides 37 are preferably arranged at the end with respect to the longitudinal extent of the liquid application device transversely to the working direction according to arrow 8 . In contrast, the guide 38 is preferably provided in the center, cf. also Fig. 3. This guide 38 consists of a mushroom head 41 with a hat 42 of round cross-section, which engage in undercut grooves 43 in the liquid application apparatus 3 a, see FIG. Fig. 7. The planar extent of the hat 42 , the formation of the undercut groove 43 , the guide recess 33 and the guide channel 44 take place in parallel planes. As a result, a pivoting movement about the central axis 45 of the mushroom head 41 with its rotationally symmetrical design is also possible with respect to the transverse extension of the liquid application device 3 to the working direction 8 with a central arrangement of the guide 31 . Such a pivoting movement about the central axis 45 is limited by the stop of the sliding parts 40 provided at the end against the top surface 46 of the guide channel 44 or other suitably designed stop surfaces.

Further displacement of the slide 25 from the position according to FIG. 6 into the position shown in FIG. 9 brings the driver 32 into contact with the boundary surface 35 . As a result, the liquid application device 3 is brought into a position protruding from the suction mouth 21 . If the latch 28 is then locked in the front recess 29 , the liquid application device 3 is supported by the slide 25 against the suction channel housing 15 . A further advancement of the liquid application device 3 can still be limited by stops of the guides 37 , 38 . In this position, only a liquid application to the cleaning surface 2 is possible.

Referring to Figs. 1 to 3 the direction Saugvor is still further explained specifically.

The surface to be cleaned 2 facing outer cross-sectional area of the suction mouth 21 is reduced to a slot-shaped suction nozzle 50 a width less than 5 mm here about 1.5 mm to 2 mm compared to a subsequent suction channel section 51 . In the suction direction, this cross-sectional constriction has a length that approximately corresponds to its width. Following the Saugdü se 50 , the extracted liquid-air mixture is deflected for the first time, for which purpose a corner 57 deflecting the flow direction is formed in the sealing lip 31 . In the further course of the suction channel section 51 adjoining the suction nozzle 50 , the sealing lip 31 merges directly and continuously into an inner wall 52 delimiting the suction mouth 21 . The flow of the aspirated liquid-air mixture is redirected again at position 54 in a Z-shaped manner in the further course of the suction channel section 51 before the liquid-air mixture enters a suction chamber 53 . This deflection 54 by cutting mutually standing surfaces 55 , 56 prevents especially in conjunction with the formation of the suction nozzle 50 a drop fen from the suction mouth 21 when the suction device is switched off.

In its longitudinal extent and thus transverse to the working direction 8 , the slit-shaped suction mouth is divided into individual suction sections 60 , cf. also Fig. 3 and the different representation in FIGS. 1 and 3, which are slightly in the suction mouth 21 Be rich transversely to the direction 8 also added. The subdivision into individual suction sections 60 serve ribs 61 of different heights and different angles. The angle of attack relative to the vertical according to FIG. 2 increases with the position of the ribs 61 towards the outside, ie towards the lateral edge regions 62 of the suction nozzle 21 . In addition, the length of the Saugab sections 60 is increased transversely to the working direction 8 to the outside. These measures ensure a uniform suction over the entire extent of the suction mouth 21 . The ribs 61 thus also enclose a multiplicity of suction channel sections 51 , which open into the common suction chamber 53 . At the common suction chamber 53 several, here two intake manifolds 63 , 64 are connected, which are shown here idealized only by the combination of path lines 65 of the suctioned liquid-air mixed flow. Further in the suction direction according to arrow 66 , the two intake manifold branches 63 , 64 essentially represented by the railway lines 65 are combined in a common suction channel cross section, in FIG. 3 by node 67 represents Darge.

Since in the embodiment of the slide 25 bezüg Lich the slot-shaped suction channel mouth 21, the Saugka channel housing 15 passes approximately in the center, the slide 25 and here the guide 38 between the intake manifolds 63 , 64 are bordered. In which the liquid applicator is not shown, the representation of FIG. 3, showing the mushroom head 41 of the guide 38 on the axis 68 lying. Also the Saugkanalgehäusefe ste pin 13 on the holding plate 14 for the spring 11 can be seen in its central arrangement with respect to the axis 68 . The pin 13 lies further between the grooves 36 for the lateral guidance of the slide 25 .

Following the summarization of the suction pipe branches 63 , 64 in the node 67 in the suction direction 66 , a phase separating device 70 is further provided here in the suction device set 1 , ie between the suction mouth 21 and the actual suction device (not shown) itself, cf. Fig. 4. The phase separation device 70 separates the liquid-air mixture into a liquid and a gaseous phase, here by the centrifugal forces caused by a flow deflection. Such a deflection of the flow can take place, for example, in a Z-shape, for example through opposing baffle walls inclined in the suction channel. Here, however, the centrifugal forces are caused by a vortex formation in the flow. The center line 72 corresponding to - - by 3 is in a swirl channel portion 71 as shown in Fig also indicated by the arrow 66, the aspirated liquid-air mixture transverse extension to the longitudinal. Of the swirl channel portion inserted into this 71. As a result, the movement of the aspirated liquid-air mixture receives its rotatory component, as is achieved in a similar manner in cyclone separators known per se. At the end of the swirl duct section 71 of the suction duct 20 , the rotating air mixture, in which the heavy ren particles, namely the particles of the liquid phase, have moved radially outward due to the centrifugal forces, meets a cross section of the suction duct 20 that almost completely fills, funnel-shaped constriction 73 . In the funnel interior 74 , only the gaseous phase is passed on. The liquid phase is separated off via the edge 75 and collected in a tank 76 . The tank 76 is rotationally symmetrical and encloses the funnel interior 74 formed as a suction channel 20 . According to the Ausführungsbei 1 have interior hopper 74 and tank 76 the game of FIG. On a common intermediate wall 77. The tank 76 is closed via a base 78 and is supported against the suction device housing 15 . In the area of the tank flow 79 , a star-shaped support 80 is indicated. Inside the tank 76 is a baffle 81 with annularly distributed passage openings 82 hen hen, which on the one hand performs a valve function when in the rear region 83 of the tank 76 is collected cleaning fluid. In addition, the baffle 81 also resiliently supports the inner wall 77 against the suction device housing 15 . As a rule, the tank 76 is preferably filled with a liquid-absorbing and liquid-storing material, so that the cleaning liquid is bound in the tank and an outflow from the tank occurs e.g. B. in the wrong handling is largely avoided.

The tank 76 is connected in the suction direction behind the tank inflow 79 of the separated liquid to the suction channel 20 , here formed by the funnel interior 74 , via suction channels 84 , 85 . As a result, a negative pressure is also generated inside the tank 76 , which supports the phase separation following the swirl channel section 71 .

Fig. 10 shows an alternative embodiment of the tank 90 , which is operatively releasably connected to the suction device attachment 91 . As a result of such an embodiment, the emptying of the tank 90 is significantly easier. For this purpose, for example, the suction device attachment 91 is to be separated from the suction hose 22 , which is easily possible after loosening a locking device 92 . The cut in the transverse ring-shaped tank 90 can then easily to the interior of the funnel extension 93 forming Wan be pushed 94 where it is then held between this wall 94 and the wall 95 of the Saugkanalgehäuses 96th In particular, filled with a liquid absorbent material 97 , the tank 90 can then also be designed as a disposable cartridge.

In the suction direction of the phase separating device 70 following and here in the embodiment, the suction channel 20 within the suction device attachment 1, finally, a surge valve 100 is also provided. With the sudden suction of larger amounts of liquid, the capacity of the phase separator device 70 may not be sufficient and a liquid-air mixture with a large proportion of the liquid phase beyond the phase separator 70 is also sucked off in the suction channel 20 in the suction direction. So that this liquid-air mixture cannot get into the suction device (not shown) via the suction line 22 , the surge valve 100 blocks the cross section of the suction channel 20 with a slide 101 , here plate-shaped, from. Fig. 8 and 9. This takes place against the force of a compression spring 102 whose spring force the closing of the slider 101 at Auftref fen determined larger amounts of liquid.

Alternatively, a splash valve can also be used, for example with a spherical slide like the one of the so-called industrial vacuum cleaners known ausbil the.  

Here, the plate-shaped slide 101 is axially guided in a pipe section 103 and in its open position allows the extracted air flow to pass through perforations 104 on the edge. In the closed position, cf. Fig. 8, the openings 104 are closed by the suction channel 20 demagnifying in cross-section annular shoulder 105, on which the compression spring 102 is supported. The slide plate arranged between the openings 104 respectively closes the free cross section of the suction channel 20 narrowed by the annular shoulder 105 .

Instead of the compression spring 102 , several tensile springs can optionally be arranged between a nose 106 fixed to the suction device housing and the supports 107 arranged in a star shape of the slide 101 tension springs.

In a further embodiment according to FIG. 11, a splash water valve 110 is shown, which has a further function. The tank 111 is here filled with a liquid-absorbing material, an absorbent 112 , which increases its volume when liquid is absorbed. Held between the radial walls 113 , 114 , however, the absorbent is only allowed an axial volume increase, for which purpose the tank 111 is designed axially with two ligaments. As a result, when the front side of the tank half 115 in FIG. 11 is opposite the suction channel housing 117 , the right tank half 116 will move to the right with an axial increase in volume of the absorbent 112 . Here, the bottom 118 of the tank 111 will move the slide 119 of the splash water valve 110 in the closing direction via a sliding intermediate part 120 during its movement. With a corresponding coordination of the closing path of the slide 119 of the surge water valve 110 and the increase in volume of the absorbent 112 due to the liquid absorption, the surge water valve 110 then closes at the moment when the absorbent capacity of the absorbent 112 is exhausted. As already described, the suction device attachment can then be removed after loosening a locking device 92 and the tank 111, constructed, for example, as a disposable cartridge, can be replaced with a new tank with the absorbent 112 exhausted in its absorption capacity. Possibly. it is also only necessary to replace the absorbent and it can also be reusable and, for example, regenerated and / or dried for reuse.

The connection of a suction attachment to a suction hose 22 is carried out in a manner known per se. The suction hose 22, for example, a conventional household vacuum cleaner is provided at the end with an extrusion coating 125 , which is locked with a connector 126 . A sealing ring 127 is provided between the connector 126 and the hose encapsulation 125 on the one hand and on the other hand here against the valve receptacle 128 . After pressing a button 130 which can be pivoted about an axis 129 against a leaf spring 131 , a catch 132 is released and the suction device attachment 1 can then be separated from the hose 22 .

It remains at the discretion of the person skilled in the art whether the surge water valve 100 remains assigned to the hose, for example, or the suction device attachment 1 . Accordingly, he will make constructive connections or separations, since there may be reasons for both possible solutions in the application.

In Fig. 12 an alternative embodiment of the phase separation device 70 is shown. Here, a flow body 150 is arranged upstream of the tank 90 filled with a liquid-absorbing material. The latter is essentially mushroom-shaped, with a first rounded, hemispherical section 151 with its rounded head side pointing in the direction opposite to the general flow direction. A second section 152 adjoining the flow direction is formed in the shape of a circular cylinder section, with an orientation coaxial to the longitudinal axis of the suction channel 20 . The diameter of the section 152 is selected to be somewhat smaller than the largest diameter of the hemispherical section 151 .

The flow body 150 is hollow, the hemispherical first section 151 having on its outside radially aligned guide vanes 153 , the tear-off edges 154 of which end at the level of the taillike transition from section 151 to section 152 of the flow body 150 .

In the step-like transition region from the first section 151 to the second section 152 , openings 155 are provided which essentially open out transversely to the axial direction.

Due to the fact that a liquid phase in the suction air stream has a higher inertia and density than a gaseous phase, conditions by using swirl in the area of the guide vanes and hard flow deflections caused by the radial openings, the liquid phase separated from the gaseous phase. The liquid phase thus separated is then taken up and stored in the tank 90 . Any residual moisture, so-called atomized liquid drops, is separated by a liquid-absorbing material 156 which is arranged in the interior of the flow body, in the area of the head side of the hemispherical section 151 , which material can be a sponge, for example.

In order to counteract a short circuit from the separated liquid and gaseous phases in the region of the transition from the flow body 150 to the tank 90 , the flow body 150 is pressed against the end face 157 of the tank 90 . For this purpose, a compression spring 158 is provided, which is supported on one end on an annular step 159 in the area of the suction channel 20 and on the other end on the end faces of the guide vanes 153 facing this spring 158 .

The selected design of this alternative phase separation device provides a position-independent separation of the liquid phase in a minimal installation space. There are functional and handling advantages, since no electrical energy and thus no energy converters, such as. B. Motors or Elektroma gnete use. Furthermore, the thus-formed phase separation device 70 has no moving parts.

In Figs. 13 and 14 a cleaning sheet is shown in detail view 160, in an alternative Substituted staltung. This cleaning cloth 160 is cut to the desired size on two opposite edge edges 161 and 162 with frame cheeks 16 forming keder-like thickenings 163 . The latter can, for example, be sprayed or glued to the cleaning cloth 160 . In the exemplary embodiment shown, a preferred embodiment is shown, in which the frame cheeks 16 or the keder-like thickenings 163 consist of the cleaning cloth material itself. This eliminates the usual flanging or concatenation of the cleaning cloth edge edges 161 and 162 . In the exemplary embodiment shown, the cross section of the piping-like thickenings 163 is selected to be circular, the cleaning cloth 160 extending in a radial orientation to the piping-like thickenings 163 between them.

As already described, the cleaning cloth 160 is stretched over the liquid application device 3 and wetted by it on the back (cf. FIG. 15). For this purpose, the cleaning cloth is placed on the application surface of the liquid application device 3 and here after the piping-like thickenings 163 are pressed into groove-like recesses 164 and 165 arranged on both sides of the liquid application device 3 . These groove-like recesses 164 and 165 are formed undercuts for the form-fitting holder. For this purpose, the groove-like recesses 164 and 165 each have an inwardly directed bead 166 and 167, at least at each edge of an opening. The piping-like thickenings 163 are pressed for fastening the cleaning cloth 160 into the groove-like recesses 164 and 165 , the recess-side beads 166 and 167 being overflowed here, this is preferably due to the flexible configuration of the thickening conditions 163 . After being pressed in, the beads 166 and 167 engage behind the piping-like thickenings 163 , for securely fixing the position of the cleaning cloth 160 on the liquid application device 3 .

In an alternative embodiment, the nutarti-like recesses 164 and 165 can be provided with resiliently deflectable cams for the form-fitting mounting of the welt-like thickenings 163 . It is also conceivable that with resiliently designed, piping-shaped thickenings 163, the attachment in the area of the groove-like recesses 164 and 165 can be made purely frictionally.

As can be seen in particular from FIG. 15, when using the suction device attachment 1, only a small area of the cleaning cloth 160 is used, based on the total area. This cleaning area 168 is identified in FIG. 13, which shows a top view of the cleaning cloth 160 , with hatching shown in dash-dotted lines. To enable the dirt holding capacity of the cleaning cloth take full advantage of 160, this has a double mirror symmetry, so that the cleaning cloth 160 keitsauftragsvorrichtung in up to four different positions on the liquid can be secured. 3

The piping-like thickenings 163 and the groove-like recesses 164 and 165 receiving these can also have other cross-sectional shapes, contrary to the exemplary embodiment shown. It is conceivable to design the cross-sections tongue and groove in the manner of a swallow tail attachment.

It is also conceivable for the piping-like thickening to form all sides of the cleaning cloth. These further piping-like thickenings are arranged at a fastening of the cleaning cloth 160 on the liquid application device 3 to the side of this device, outside the groove-like recesses. Here it proves to be particularly advantageous if these further welt-like thickenings form a resilient connection of the welt-like thickenings 163 to be pressed into the recesses 164 and 165 .

The selected design of the cleaning cloth 160 provides an inexpensive, simple and quick way of fastening the cloth 160 to the liquid application device 3 . The attachment is structurally small and self-explanatory at the same time. The cleaning cloth can be changed with one hand. The second hand holds the suction attachment 1 . Furthermore, the cleaning cloth 160 including the fastening elements in the form of the welt-like thickenings 163 is washable.

If the cleaning cloth 160 is encapsulated with a plastic jacket, then costly, sewn hems or wrapping are eliminated. The cleaning towel 160 can be produced fully automatically. It proves to be particularly advantageous that the use of the same or similar materials for the cleaning cloth 160 and the welt-like thickenings 163 gives good recyclability.

In Figs. 17 to 24 is an alternative Ausgestal processing with respect to the fastening of a cleaning cloth shown 160th This cleaning cloth 160 is stretched over the liquid application device 3 of the suction device set 1 and wetted on the rear side by the device 3 (cf. FIG. 18). For this purpose, the cleaning cloth is placed on the application surface of the liquid application device 3 and then frame cheeks 16 , which are designed as piping-like thickenings 163 , are arranged on both sides of the liquid application device 3 , groove-like recesses 164 and 165 .

The design of the groove-like recess 164 and 165 is chosen so that each recess 164 , 165 has sections 169 , 170 offset along its length at right angles to its longitudinal axis xx. In the exemplary embodiment shown, eight offset sections 169 , 170 are formed over the length of a groove-like recess 164 , 165 .

The formation of the recess 164 nutar term is exemplified with reference to FIGS. 19 to 24. Each section 169 and 170 of the groove-like recess 164 is composed essentially of an inlet area 171 or 172 pointing towards the groove opening and a socket area 173 or 174 on the groove bottom side, the latter areas being enlarged in cross-section compared to the entry areas 171 , 172 . The arrangement is such that the socket areas 173 , 174 run in on one edge into the associated entry areas Che 171 , 172 in alignment. Due to the cross-sectional enlargement of the socket areas 173 , 174 between these and the associated groove opening stegar term, protruding into the respective entry area 171 , 172 de projections 175 , 176 are formed.

The sections 169 and 170 are formed so alternately over the length of the groove-like recess 164 that the projections 175 , 176 parallel to the longitudinal axis xx of the groove-like recess 164 and facing this axis form a slot-like passage opening 177 over the length of the groove-like recess 164 . The individual socket areas 173 and 174 form here, considered over the length of the groove-like recess 164 , an approximately the contour of the frame ge to be inserted 16 or the welt-like thickening 163 adapted receiving space 178 (cf. FIGS . 22 and 23).

In the course of the assembly of the cleaning cloth 160 , the piping-like thickening 163 is pressed into the groove-like recess 164 or 165 . Due to the staggered arrangement of the individual sections 169 and 170 for inserting the welt-like thickening 163 , a slight deformation thereof is necessary. The welt-like thickening 163 is pressed in in a wave shape, following the entry regions 171 , 172 of the offset sections 169 , 170 . Thereafter, the welt-like thickening 163 in the area of the receiving space 178 formed automatically springs back into an elongated, straight alignment along the longitudinal axis xx of the groove-like recess. The cleaning cloth 160 adjoining the welt-like thickening 163 passes through the slit-like passage opening 177 .

This configuration according to the invention is a simple, secure attachment option with a a keder strip provided cleaning cloth without moving or additional parts by inserting them in a length offset groove for the welt strip ben. The latter can, for example, from the material of the Reini exist and be sewn. Continue there is the possibility of a piping strip on the Reini sew on, weld or spray on.

The piping strip is straight when inserted, must however, are easily deformed for assembly so that they cannot fall out of the holder by itself.

It proves to be advantageous here that the piping-like thickening 163 is used as a spring, which means that it is attached to the replacement part (the cleaning cloth 160 ). The clamping force is almost arbitrarily adjustable by the dimensions of the groove-like recesses 164 , 165 .

Because in the area of the latter no moving or after extensively designed parts are necessary, the area the groove-like recess can be designed solid.

Alternatively, the staggered sections of the groove-like recess can also be designed such that after the welt-like thickenings 163 have been introduced , which can also be done by lateral insertion, they continue to be slightly wavy, following the contour formed by the sections. As a result, the cleaning cloth 160 is additionally clamped in the region of the welt-like thickening 163 .

In order to offer easy disassembly of the cleaning cloth 160 , a finger grip opening 179 is provided. This is formed in the region of a side wall 180 of the suction device attachment 1 , with enforcement of this side wall 180 . This finger-behind handle opening 179 replaces a small length range of the groove-like recess 164 or 165 , so that a portion of a frame cheek 16 or a kederarti gene thickening 163 in the finger grip opening 179 is completely exposed. This exposed section can thus be gripped in the simplest way. Thereafter, the cleaning cloth 160 is removed either by pulling out the welt-like thickenings 163 from the groove-like recesses 164 or 165 along the axis xx or by pulling out the welt-like thickenings 163 from the recesses through the entry regions 171 , 172 formed in the offset sections 169 , 170 .

In FIG. 25, a further alternative Ausgestal is below the phase separator 70 shown in Fig. 12. Here, the flow body 150 , which is arranged upstream of the tank 90 provided with a liquid absorbing material, is likewise provided with guide vanes 153 , but here these guide vanes 153 are of continuous, helical configuration. The guide vanes 153 form a two-start screw thread, coaxial to the longitudinal axis of the suction channel 20 . The flow body 150 is rounded, hemispherical in gel-like configuration, the rounded head side pointing in the direction opposite to the general flow direction. Here, the diameter of the flow body 150 is selected to be smaller than that of the suction channel 20 receiving the flow body 150 .

The guide vanes 153 arranged in a helical fashion around the flow body 150 terminate radially with the inner wall of the suction channel 20 , which means that in a preferred embodiment in which the flow body 150 and the guide vane 153 are connected to one another in the same material, the guide vanes 153 provide the radial support of the flow body 150 cause in the suction channel 20 .

The flow body 150 provided with the guide vanes 153 is positioned at a distance from the tank 90 , viewed in the direction of flow, in front of the latter. A free space 200 is thus created between flow body 150 and tank 90 .

Through the continuous, helical guide vanes 153 , the liquid phase is safely separated from the gaseous phase, the separated liquid phase is then taken up and stored in the tank 90 . Di 01458 00070 552 001000280000000200012000285910134700040 0002019719932 00004 01339e, due to the selected design of the guide vanes 153 without residual moisture, the gaseous phase flows out of the free space 200 after leaving the guide vanes 153 .

A configuration is also conceivable here, in which the flow body 150 - as already described with reference to FIG. 12 - is designed as a hollow body and the flow body 150 is followed by a second section in the direction of flow adjoining the circular cylinder section, the diameter of which is chosen to be smaller than the largest diameter of the hemispherical flow body 150 . This second section has transverse radial openings leading to the axial direction, through which the volume flow separated from the liquid phase passes. A sponge or the like can be arranged in the interior of the flow body in the area of the head side.

All the features disclosed are essential to the invention. In the disclosure of the application is hereby also the Disclosure content of the associated / attached priori full documents (copy of the pre-registration) Lich included, also for the purpose of characteristics of this Documents in claims of the present registration with to record.
