Description

Field of invention

The invention relates to a device for grouting joints between floor or wall coverings, in particular clinker bricks, tiles or tiles, with a magazine holder which has a receiving space for receiving a joint compound, the receiving space being transversely formed by two opposing side walls and one facing the joint is limited between the side walls and the ceiling wall arranged parallel to the joint, and wherein the ceiling wall can be displaced perpendicular to the joint via at least one thrust element relative to the side walls

The invention further relates to a method for grouting with a device according to claims 1 to 8.

State of the art

From the DE 20 2010 006 664 U1 a device and a method for grouting joints between floor or wall coverings, in particular tiles and tiles, are known. The device has a magazine holder with a receiving space for receiving a joint compound, the receiving space being delimited by two opposing side walls and a top wall facing the joint, arranged transversely between the side walls and parallel to the joint. The top wall can be displaced perpendicular to the joint by means of a sliding element relative to the side walls.

The disadvantage of the known device is that the receiving space is surrounded at its lower opening facing the joint by an outwardly protruding, horizontal flange which runs parallel to the jointing surface, the opening being larger than the width of the joint to be jointed. The walls of the receiving space are rigid due to the circumferential flange. In this respect, an additional sealing edge is required on the underside of the flange in order to prevent grout from escaping from the side and additional wipers. It is also relatively difficult to position the device exactly over the joint. Furthermore, it is relatively difficult to fill the receiving space of the known device with grout.

From the GB 2 150 198 A a device and a method for grouting joints are known in which a type of mortar funnel is designed as a trough-shaped container which is open at the top and tapers at the bottom to a slot-shaped opening. The slot-shaped opening has two mutually parallel flexible side walls on its long sides.

The disadvantage of the known device is that no pressure can be built up in the tub-shaped container and the mortar supply must therefore be relatively liquid. In addition, the width of the slot, i.e. the distance between the side walls, must not be greater than the width of the joint to be grouted. The device is therefore relatively difficult to position in the joint.

Task

It is therefore the object of the present invention to improve the known device in such a way that it is easier to use. In particular, the receiving space of the device should be easy to fill with joint compound, and the device should be able to be positioned easily and safely in relation to the joint to be jointed.

Correspondingly, the grouting method should also be able to be carried out more easily and safely.

Statement of the invention

This object with regard to the device is achieved in connection with the features of the preamble of claim 1 in that the side walls are elastic and have free ends protruding from the magazine holder so that the magazine holder can be inserted into the joint with its free ends of the side walls that the joint compound arranged in the receiving space can be emptied into the joint by a relative movement between the top wall and the free ends of the side walls, and that at least one of the free ends of the side walls is angled inwards at an angle of inclination between 4 ° and 8 °.

Because the side walls have ends protruding from the magazine holder and are designed to be elastic, the receiving space can be filled into a grout supply simply by placing it on and pressing it in. On the one hand, the elastic and resilient ends help to ensure that the joint compound does not fall out of the receiving space and, on the other hand, the receiving space is easier to place in the joint. The fact that the magazine holder can be inserted into the joint with its free ends of the side walls means that the seal known from the prior art can be dispensed with, since the joint compound is reliably prevented from escaping from the side by inserting the free ends of the side walls. The angulation of at least one of the free, elastic ends of the side walls by an angle of inclination between 4 and 8 ° on the one hand contribute to the fact that the joint compound arranged in the receiving space does not fall out unintentionally and on the other hand the device with its receiving space can be more easily placed in the joint.

Due to the relative movement between the top wall and the free ends of the side walls, the top wall presses on the joint compound arranged in the joint, while the free ends are withdrawn and the joint compound is pressed laterally against the joint delimitation. The device can also be used easily and safely by inexperienced persons, for example do-it-yourselfers. The device has an independent material receptacle and one-handed operation. The jointing material is transported freely.

The device is particularly suitable for grouting clinker walls or facing masonry with clinker brick slips or for other exposed masonry.

It has proven particularly useful that the free ends of the side walls are each angled inwards by an inclination angle of 6 °. The side walls are on the one hand height adjustable and on the other hand interchangeable and can easily be exchanged as wearing parts.

According to a further preferred embodiment of the invention, the top wall is designed as a joint trowel, via which the joint compound can be pressed into the joint.

According to a further preferred embodiment of the invention, a height-adjustable smoothing trowel is located in front of the receiving space at one end, the setting of which allows the depth of the joint to be determined. In particular, it can thereby be determined whether the joint compound ends with the outer edge of the joint or forms a shoulder with respect to the outer edge. The smoothing trowel is exchangeable and can therefore be adapted to different joint widths.

According to a further preferred embodiment of the invention, the receiving space is designed as an exchangeable magazine arranged on the magazine holder. As a result, the device can be adapted relatively easily to joints of different widths and lengths.

According to a further preferred embodiment of the invention, the magazine holder is arranged on a base body which carries a displaceable handle part which is connected to at least one push part. The top wall can be displaced around the handle part against a spring force in a plane terminating with the free ends of the side walls.

This enables simple and safe one-handed operation of the device.

1. a) Aufsetzen der Vorrichtung mit ihrem Aufnahmeraum in einen Fugenmassevorrat und Auffüllen des Aufnahmeraumes mit Fugenmasse durch Eindrücken des Aufnahmeraumes in den Fugenmassevorrat,
2. b) Einsetzen der Vorrichtung mit den aus dem Magazinhalter herausragenden freien Enden der Seitenwände des Aufnahmeraumes in die zu verfugende Fuge, und
3. c) Freisetzen und Verpressen der Fugenmasse in der Fuge durch eine Relativbewegung zwischen Deckenwand und den freien Enden der Seitenwände.

The object with regard to the method is achieved in connection with the preamble of claim 7 in that the following steps are carried out:

1. a) placing the device with its receiving space in a grout supply and filling the receiving space with grout by pressing the receiving space into the grout supply,
2. b) inserting the device with the free ends of the side walls of the receiving space protruding from the magazine holder into the joint to be jointed, and
3. c) releasing and pressing the grout in the joint by a relative movement between the top wall and the free ends of the side walls.

The receiving space of the device can be easily filled with the amount of grout given by the volume of the receiving space by simply pressing the receiving space into the grout supply. The insertion of the device into the joint to be grouted is correspondingly simple and problem-free, in particular due to the free ends of the side walls of the receiving space protruding from the magazine holder. The joint compound is then released and pressed in the joint by a relative movement between the top wall and the free ends of the side walls via the displaceable handle part, likewise easily and without problems.

According to a further preferred embodiment of the invention, in a subsequent step

• d) the grout is smoothed with the smoothing trowel positioned in front of the receiving space at one end.

The smoothing trowel has the advantages already described above.

Further features and advantages of the invention emerge from the following specific description and the drawings.
