EP1233121A2 - Hand-held device for distributing pasty products on floors - Google Patents

Abstract

The hand tool to spread a paste mass over a floor, e.g. an adhesive or cement, has a reservoir (1) for the mass contained within a rectangular zone (8) formed by four walls (2-5). The longer longitudinal walls (2,3) are angled outwards, so that the reservoir zone has an increased downwards cross section surface area against the floor. The shorter walls (4,5) are vertical and at right angles to the floor, and can be pushed vertically over a stretch against the longer side walls to set the thickness of the spread mass over the floor.

Description

The present invention relates to a hand-operated distribution device a pasty mass, in particular an adhesive or a cement mortar, on a floor as described in the preamble of the claim 1.

The distribution of a pasty mass on a floor is general Common technology for fastening floor coverings such as slabs or Carpets on the cement floor and for filling the joints, that remain open after laying between the panels. In the former case it's generally about getting an adhesive in shape on the floor of parallel strips, between which space remains free, through which the air can escape. A continuous layer of glue allowed no complete removal of all air bubbles between the surface and remain trapped on the floor. For this operation, therefore, is usually a trowel or spatula, comb-like with a toothed Edge are provided, by means of which the adhesive in parallel threads or strips can be distributed. However, are the still open joints grouting between the already laid floor slabs with cement a trowel with a smooth edge is used because in this case the gaps should be filled in between the slabs without excessive traces of cement to leave. These two operations differ in their purpose and in the materials used, but have in common, that they are still carried out using very simple hand-operated tools and that they are very tedious operations with great physical Represent effort. In particular, be it with the distribution, or Brush in the broadest sense, a tough adhesive, or be it with Filling the joints between the floor slabs with a very liquid cement mortar, mostly worked on the knees with a hand trowel. The too distributing mass is poured onto the floor on which it is located immediately spreads out and forms a "lake", whereupon she is picked up with a trowel and brought to where it is needed. This operation is not only tedious because of the working position on the knees to which the Flooring is forced, but also has the disadvantage that it is very difficult to put on long strips of glue, for example range from wall to wall, as desired, however, when floor slabs or moquette carpets are to be laid. In this case it is from Advantage of applying the adhesive in strips, i.e. Apply an adhesive web for example about the width of a row of plates (e.g. 30 or 40 cm), of course in the form of narrow parallel stripes, and then Lay the slabs along the entire length of the created sheet before one another series of plates is being tackled. The same applies to that Laying of carpet goods, or of Moquette carpet, all over Roll out the room width from wall to wall. The conventional way Pour out glue in some areas and with the help of a trowel or Distributing spatulas complicates the process, perfect strips of glue "by Wall to wall ". The same difficulty occurs for the plate layer also in the second step, namely when filling the joints on one smooth slab floor. Here too the pouring out of the mass causes which is particularly fluid in this case, the formation of cement lakes that are not required, which are particularly disadvantageous when you consider that in this If only narrow and straight joints or incisions are to be filled.

From the patent literature are various suggestions for improving the Working conditions of the floor layer known in two clearly different Categories can be divided: those of the more or less complex Handcuffs, and in those of the wheeled wagons.

The first category includes, for example, GB-750160, which is an applicator, or shows an application device with a reservoir, with an outflow opening to the floor and with a valve to open and close the outflow opening. The device, which because of the final valve actually already as one Machine could only be viewed in one direction, so the glue in a thin strip only in one direction of travel can be applied. This means that to attach a strip of glue from wall to wall the device near the Wall must be rotated 180 °, the outflow opening for this step closed for the glue and after turning the device must be opened again. In addition to this disadvantage, it should also be mentioned that the construction of the device is relatively complex and considerable Maintenance required (just think about cleaning after work to prevent the parts of the device from sticking together), and that there is no possibility for the floor layer to work on it to spare the knees. Therefore, this construction has no practical application found in the area of the floor layer.

Further suggestions of more or less "technological" trowels are for example in US-4254980, US-4982470 and US-5379479, wherein those in the latter two patents prefer to have the Show possibility to work in a standing position, which already has one great advantage over the normal trowels with which kneeling has to be worked. Nevertheless, according to these documents, only a conventional trowel for use, on which only an extension rod is attached so that the problem of the desired good distribution the pasty mass in longitudinal strips of clearly defined width is not resolved. Again, the pasty mass is emptied onto the floor in one place and is distributed from there over a more or less extensive area.

So this is, as in the case of using a conventional one Trowel for poorly controlled spreading of the adhesive or cement mortar. More recent, which shows the fact that the conventional Hand trowel is still in common use today, is a suggestion to improve the grip, the better in the hand and cramps should avoid that can occur in the user who spends hours with such Tools must work: Compare the proposal in EP-0855230.

That the use of trowels to distribute pasty masses on the Soil, especially because of the poor working position, is quite exhausting Work was discovered 30 years ago, namely since solutions were proposed on a distribution truck for glue and the like are based: Reference should be made, for example, to DE-PS-597545, DE-2334942, DE-A-2709771, FR-A-2441701, US-A-4575279 and EP-A-047863.

All of these proposals have the disadvantage that, apart from that they are actual machines and are therefore expensive, only in can work in a single direction so that it is not possible to Distribute glue or the cement mortar "from wall to wall" without the Turn the trolley by 180 °. For such reasons, such solutions have although they are in areas such as asphalting roads or Formation of large concrete surfaces could not be used Plate laying work or Moquette laying work found as it is for this No sufficient benefits in terms of practical handling or work Offer costs.

The present invention therefore aims to provide a hand-operated device to create to distribute a pasty mass, especially one Adhesive or a cement mortar on a floor that is easy to set up and should be practical to use, and capable of the pasty mass "from wall to wall" (i.e. from a wall of the room to the opposite wall) in one step and without the Need to apply the device by 180 °. The inventive Device should also be inexpensive to manufacture and thus be affordable even for the smallest companies in this field.

These objectives are met with a device that has the properties according to the characterizing part of claim 1.

In a preferred embodiment variant, the device according to the invention is intended also allow the floor layer to work standing, whereby he can avoid the kneeling work position, the cause of an entire There are a number of health problems that the plate layers and the carpet and Moquette publishers are well known.

a construction detail showing the fastening device by means of which the shorter walls can be fastened in a fixed vertical and / or horizontal position.

1, the device according to the invention is simplified in perspective Representation shown, but in which all important elements for the invention are shown. In particular, a reservoir 1 can be seen that consists of four walls (2, 3, 4, 5), which enclose a room 8, which the distributing mass 6 (see FIG. 2) encloses, depending on the intended Use an adhesive or a cement mortar, and their Consistency can be more or less firm (firm for the adhesives, liquid for grouting cement mortar, etc.), the space below through the floor 7 is limited, the reservoir 1 being open at the top.

According to the present invention, the one of the four walls 2 to 5 enclosed space 8 rectangular shape, the two longer Side walls 2 and 3 of the rectangle at an angle a in such a way are arranged inclined outwards so that the space 8 increases downwards Has cross-sectional area when the reservoir 1 on the floor 7 stands. This eases the more or less dense mass flow below and therefore adhere better to the ground. Furthermore, the two Walls 4 and 5, which form the shorter side walls, essentially arranged perpendicular to the floor 7 and can be perpendicular to the walls 2 and 3, which form the longer side walls, by a distance t in the Height can be adjusted, which is the thickness of the to be distributed on the floor 7 Layer of the pasty mass.

Various construction solutions come into question for realizing these Adjustment of the walls 4, 5 relative to the side walls 2, 3. In the simplest and therefore preferred embodiment of the present Invention is provided that the two walls, which are the longer side walls 2, 3 form, are connected so that they are rigid Box with two inner walls 9, 10 form the shorter in their lower areas are than the walls 2, 3, so that between the lower edges 11 or 12 and the floor 7 a gap of the height T (Fig. 2) remains free if that Device with the lower edges 22 of the longer side walls 2, 3 forming Walls on the floor 7, the height T is always greater than that Layer thickness t is. The space T never determines the layer thickness of the pasty mass to be distributed on the floor. The movable walls 4, 5 are on the inner walls 9, 10 by means of suitable connecting and Fasteners attached. Such fasteners can, for example, as shown in FIG. 2, be designed as grub screws 13 which firmly attached to the fixed inner walls 9, 10, e.g. welded and which extend through slots 14 of a suitable size, the free displacement of the walls 4, 5 relative to the "support walls" 9 and 10 allow, and which are provided with wing screws 15, by means of which the walls 4, 5 in the vertical and horizontal with respect to the fixed inner walls 9 or 10 desired position can be tightened in such a way the distance t, which determines the thickness of the applied mass, can be adjusted. The distance t can of course also be on everyone Side of the device can be set to different values, which is especially important can be useful, as explained below, when the wear the lower edges of walls 4, 5, which are most stressed during work should be kept as small as possible.

According to a first preferred embodiment variant of the present invention are the two walls 4, 5, which are the shorter sides of the reservoir Form 1, with a straight lower edge. With this solution, which is not shown in the figures, except in one of its variants 5, which is to be described below, can thus on the Bottom a homogeneous layer of the pasty mass with the layer thickness t created , whereby the value t can have very small values, or if the device is used to fill joints between two panels or if a rough floor is to be smoothed down to zero can be.

According to another preferred embodiment of the present invention, which is shown in Figures 1 to 3, the two walls 4, 5, which form the shorter side walls of the reservoir 1, with teeth 16 provided by means of which parallel strips of the pasty on the floor Mass can be applied if the device is at right angles to the shorter walls 4, 5 is moved. These strips of adhesive (in the figures (not shown) are essentially the same as those with a normal serrated trowel of the plate or carpet layer. It it is known that when laying tiles or carpets the adhesive in parallel strips a few millimeters wide can be applied must, whereby there must be free space between the stripes, through which the air can escape when the tiles or carpet are laid become. If such air channels are missing, they form under the plates or under Air bubbles in the carpet so that it does not adhere properly to the floor comes about. The dimensions of the teeth 16 can vary depending on the intended Operations can be selected differently. For this reason can be provided that the walls 4 and 5, which are opposite the rest Part of the reservoir 1 are fixed against walls with another Teeth 16 can be replaced, in which case the walls 4th and 5 exchange walls can be named, or according to a preferred one Solution, which is shown in Figures 1 and 2, the lower area the walls 4, 5 provided with a milling 17 in which a thin strip 18 is inserted, which is provided with a downward toothing is; such a serrated strip can be easily pulled out and through another will be replaced. Changing the stripe, of course made of very hard and abrasion-resistant material (steel alloys or ceramic Materials, etc.) must be made for two main reasons: Be it about the perforation and thus the shape of the applied to the floor Strips of pasty mass (with regard to layer thickness, distance, etc.) to change, or be it to replace toothed strips by the use is worn out. It should be remembered that in the process the streak formation on the floor is sufficiently strong on the device Soil must be pressed, which is quite abrasion in the places of Causes teeth 16 that touch the ground so that the teeth become light wear out. For this reason too, the shorter side 4 or 5 on the front side while moving the device in a certain Direction, preferably a little off the ground. 2, the Device on the floor from left to right in the picture shifted, as indicated by the arrow f. In this case the wall 5 on the left side of the device in the illustration is lowered so far, that the perforation 16 of their toothed strip 18 covers the floor 7 just touched and glue strips 19 put on it, while the wall 4 on which is slightly raised in the right side of the illustration, so that its perforation 16 no longer touches the ground. However, the pasty mass 6 flows not from the gap left open under the raised serrated Strip 18 of the wall 4, since it is too viscous and therefore opposite the device, which moves forward, is pulled "backwards".

According to another preferred embodiment shown in FIG. 3 the present invention provides that the walls 4, 5, which the Form shorter sides, also sideways or in the opposite direction Pages 2, 3, which form the longer sides of the device, moved can be. From Fig. 3 it can be seen how the wall 4 shifted to the left can be (position shown in dashed lines) opposite the position in the middle (shown with solid lines). This possibility can can be realized by providing openings 14, for example Diameter is larger than that of the fastening screws 13, so that the walls 4 and 5 laterally opposite the fixed walls 9 and 10 are movable, which can be useful when you apply the pasty Dimensions as close as possible to a wall of the room or the skirting board wants to get there. If the wall 4 or 5 moved to the wall in question , the outer edge of the toothed strip 8 grazes along the edge of the room, leaving the glue to the very rear Angle is distributed.

According to a further preferred embodiment of the present invention, that shown in Figures 1, 2, 3 and 5 are the walls 4, 5 which form the shorter sides of the device, in its upper edge region each provided with a handle 20, by means of which the operator can grasp the device with both hands.

According to a preferred embodiment, the walls 4, 5 have which form the shorter sides of the device, a total height H on and with their extension reach a height of 400 mm above the floor. It is important with regard to the advantages that the inventive The device provides that the device according to the invention is used while standing can be, and not in a kneeling working position like the normal one today Use a hand trowel to spread the adhesive. For this Practical experience has shown that the handles 20 on one Favorable height above the floor 7 must be attached, whereby for Medium sized people (about 170 cm) a height of 500 mm than that greatest height can be seen. Even better, is still for medium-sized people Size, a height H of 400 mm, because the floor layer is correct Doing his work put some pressure on the distributor to ensure that the adhesive is pressed well onto the floor becomes. For this purpose, the floor layer must weigh down on the Handles 20 can support without using muscle strength of the arms to not tire unnecessarily. For this reason, the height of the handles 20 not be chosen too high, of course the body size of the Floor layer must also be taken into account. The height H of 400 mm is therefore ideal for people of medium height of about 170 cm: for people who are taller or smaller, the ideal height varies accordingly over many centimeters.

According to a further preferred embodiment variant of the present Invention, which is shown in Figures 1, 2, 4, and 6, have the walls 4, 5, which form the shorter side walls, a fastening device on which their fastening in fixed vertical and / or horizontal Positions allowed so that the thickness and / or the height of the floor 7 applied layer of pasty mass 6 can be determined. On such fastening system, which has already been mentioned above, can be designed in the simplest way by means of grub screws 13 and wing screws 15 and with openings 14 provided in the walls 4, 5 which are much larger than the diameter of the set screws 13. In this case the wing screws 15 are loosened, the corresponding wall in the position 1 brought and tightened the screws again. If you don't have every Times loosen the wing screws 15 and tighten again, can under the Screw 15 a spring 21 is inserted, which clamps the walls 4 and 9 together, and by means of which the wall 4 opposite the fixed one Wall 9 can be held in any position. If you now pulls the appropriate handle 20 or moves it correctly, you can Move wall 4 without loosening the wing screws 15. However, the solution shown in FIG. 6 represents only one of many conceivable variants of fastening systems with which the position the walls 4, 5 can be easily adjusted by moving the handles 20 can. Other fastening systems, for example with borders that can be moved by means of the handles 20, etc., are quite conceivable and it is left to the designer's imagination, simple, inexpensive and create effective solutions.

As already mentioned, the lower one rubs when moved Edges of the device on the floor 7 to apply a very pasty Mass, for example an adhesive and for producing the strips, the danger of very strong wear of the edges mentioned.

The invention provides for avoiding or reducing this risk of wear before that the lower edges of at least two of the four walls 2, 3, 4, 5, which form the reservoir 1, from a sheet 22 (FIG. 1) made of extremely abrasion-resistant Material exist that is interchangeable at the corresponding Wall is attached. 1 shows, for example, how the longer one Wall 2 of the reservoir at its bottom with a leaf (or one Edge) 22 is provided. Such an edge, in any suitable way and can preferably be attached interchangeably (for example by means of Adhesive, with a fastening groove, similar to the milling 17 of the Walls 4, 5 with fastening screws), can be made of very hard high-alloy Steels consist of or from ceramic materials, etc. The advantage of a such solution is obvious and needs no further explanation.

According to a further variant of the embodiment shown in FIG. 6 of the present invention is intended to perform a particular one Work, namely to fill the joints between the panels with one low-viscosity cement mortar without any risk that the plate surface with the To scratch the spreader that the bottom edges of at least two of the four walls 2, 3, 4, 5 are made of an elastically deformable material, in particular from very elastic natural rubber or synthetic Rubber. 5 shows how on the lower edges of the walls 2, and 5 (which also applies to walls 3 and 4) foam rubber strips 23 or 24 are attached, for example glued, the purpose of which is merely consists in the low-viscosity cement mortar with which the joints 25 between the laid panels 26 are filled together. In the Fig.5 shows the device during the shift that the floor layer with your hands from left to right in the direction of the arrow: The device leaves traces of the cement mortar with which the joints 25 were filled are, while the elastic strip 24 has the task of the surface wipe off the slabs and keep them free of cement residues. Also in this step it is advantageously provided that the strips Foam rubber 23, 24 can be easily replaced, as it is these are consumable parts of the device.

As practical experience has shown, the ideal dimensions are for to choose most applications of the device according to the invention that the length of the walls 2, 3, which form the longer sides, between Are 20 and 80 cm long, and that the walls 4, 5, which are the shorter sides of the device are between 10 and 40 cm long. The ideal dimensions depending on the type of pasty to be processed Mass or depending on the type of work to be performed. As a general rule applies that the ideal dimensions of the reservoir, the heavier and the tougher the pasty mass, the smaller can be chosen because that Dragging a very pasty mass requires greater effort required by the operator. The choice of optimal dimensions thus depends on the type of work for which the device according to the invention is provided. Therefore, it should already be stated here that the inventive If necessary, an additional device can also be added to the device improve working conditions, such as a blender that the mass in the reservoir 1 mixes during the process, or others Types of auxiliary devices (dispensers for hardening products, etc.). all of this without going beyond the scope of the present invention.

Finally, it should be noted that the angle α, which the planes form, in which the longer sides 2, 3 are preferably between 5 ° and 30 °, also depending on the type of pasty mass to be processed.

• Zuerst wird das Gerät mit seiner grösseren, nach unten gerichteten Seite auf den Boden 7 gestellt, und die Wände 4, 5, welche die kürzere Seite des Gerätes bilden, werden in ihrer Höhe so eingestellt, dass die gewünschte Schichtdicke der pastösen Masse 6 auf dem Boden 7ausgetragen wird.
• Danach wird das Reservoir 1 bis zu einer bestimmten Höhe mit der pastösen Masse 6 gefüllt,
• Sodann wird das Gerät von Hand so verschoben, dass eine erste Bahn der pastösen Masse 6 (die zum Ankleben von Platten 26 oder von Moquette-Teppich dient, oder zum Verfüllen der Fugen 25 zwischen den Platten 26), während das Gerät in der Richtung parallel zu seinen längeren Wänden 2, 3 über den Fussboden gezogen wird, bis die Wand des Raumes erreicht ist,
• Worauf das Gerät von Hand auf dem Fussboden 7 seitlich verschoben wird, um eine Strecke, die im Wesentlichen der Länge der Wände 4, 5 entspricht, welche die kürzeren Seiten der Vorrichtung bilden, und sodann
• Wird die Höhe der Wände 4, 5, welche die kürzeren Seiten der Vorrichtung bilden, so einreguliert, dass die erwünschte Schichtdicke der pastösen Masse 6 auf dem folgenden Bodenstreifen auf den Boden 7 ausgetragen wird, und schliesslich
• Wird das Gerät in der entgegengesetzten Richtung, entgegen der Richtung für die erste Bahn, über den Boden 7 gezogen, so dass eine zweite Bahn mit der pastösen Masse 6 belegt wird.

With regard to the use of the device according to the invention, it has been found that the application is preferably carried out in the following sequence of work steps:

• First, the device is placed with its larger, downward facing side on the floor 7, and the walls 4, 5, which form the shorter side of the device, are adjusted in height so that the desired layer thickness of the pasty mass 6 on the Soil 7 is discharged.
• Then the reservoir 1 is filled to a certain height with the pasty mass 6,
• The device is then moved by hand so that a first sheet of the pasty mass 6 (which is used to glue panels 26 or Moquette carpet, or to fill the joints 25 between the panels 26), while the device is parallel in the direction is pulled over the floor to its longer walls 2, 3 until the wall of the room is reached,
• Whereupon the device is moved laterally by hand on the floor 7, by a distance which corresponds essentially to the length of the walls 4, 5 which form the shorter sides of the device, and then
• If the height of the walls 4, 5, which form the shorter sides of the device, is adjusted so that the desired layer thickness of the pasty mass 6 is discharged onto the floor 7 on the following floor strip, and finally
• If the device is pulled over the bottom 7 in the opposite direction, opposite the direction for the first web, so that a pasty mass 6 is covered on a second web.

It should be remembered that in certain cases before moving sideways the device according to the invention by a distance that essentially corresponds to the length of the walls 4, 5, at most an additional operation must be provided, namely a shift of the device in the longitudinal direction of the web just coated, and more precisely, exactly by a distance that corresponds to the length of the longer side walls 2, 3, after the height of the shorter side walls 4, 5 was set so that the desired layer thickness of the adhesive mass 6 is fixed on the bottom 7 is. This is done to strip the adhesive mass on the to complete "previous path". Only after this additional "Backward" longitudinal displacement of the device will move the device to the side next lane moved to make it available for occupying the next lane. The specialist in the field will in any case carry out the execution the mode of operation most suitable to him choose.

The main advantage of the device according to the invention lies in its simplicity compared to known devices such as wagons on wheels, and in particular in its ease of use, which allows the floor layer to stand to work without having to slide on your knees, and especially compared to the serrated handcuffs with extension rods according to the prior art, wherein he has a reservoir available for long work in excellent working conditions is sufficient.
