Description

The invention relates to a device for leveling both horizontal and vertical surfaces during tile work.

Various variants of devices for leveling the surface during tile work are widely known in the art.

Documents US 2008236094 A1 and AU 2012101175 A4 disclose similar devices for leveling the surface when carrying out tile work, which includes two plastic parts - a stud and a wedge. The hairpin is made in a T-shape in a longitudinal section, which with its flat part fits into the solution (tile adhesive) under the tile, and the “tail” is clamped on both sides by adjacent laid tiles. There is a hole in the “tail”. The wedge is also made of plastic and, after laying two adjacent tiles and a hairpin between them, is driven into the hole of the “tail” of the hairpin, thereby aligning the outer surfaces of both adjacent tiles. After drying of the tile adhesive, the “tail” of the stud breaks off.

The disadvantage of the device according to the document US 2008236094 A1 is that it can be used with a limited range of tile thicknesses, since the stud has a hole bounded on the bottom side.

The disadvantage of both devices disclosed in the above documents is that the wedges are made of a large amount of plastic, and therefore are expensive elements.

Thus, the technical result to which the claimed utility model is directed is to simplify the part itself, without losing its strength and durability.

The specified technical result is fully achieved by a set of features of an independent paragraph of the claimed formula of the utility model.

A device for leveling horizontal and vertical surfaces when performing tiled work includes a stud and a wedge, which are made of plastic. The hairpin is made in a T-shape with a tail part and a working part. The working part is made flat and adjoins its middle part to the lower part of the tail part. The tail part is made in a U-shape, adjoining with its legs in the working part of the hairpin. The legs in their lower part have a place of weakened strength. The wedge is made in the form of two main rectangular plates adjacent to each other with their one smaller sides with the formation of an acute angle. On the remaining sides, the main plates of the wedge are connected by perpendicular longitudinal and transverse additional plates, forming a wedge cavity. In addition, in the middle between the longitudinal additional plates parallel to them is the middle plate, passing inside the wedge cavity, dividing it into two equal parts. Two transverse inner plates are also provided inside the wedge cavity, which extend parallel to the transverse additional plate and divide the inner wedge cavity into three equal parts. The middle plate and the transverse inner plates act as stiffeners. Moreover, the middle plate and the transverse inner plates are made thinner than the main and additional plates.

This implementation of the wedge ensures the durability of the device as a whole, and lead to a decrease in its cost, without losing its strength.

On the outside of one of the main plates are “steps”, providing a more reliable placement of the wedge in the hole of the stud.

Further, the claimed device is presented in more detail in the accompanying drawings, in which:

FIG. 1 - hairpin, side view,

FIG. 2 - longitudinal section of the stud,

FIG. 3 - wedge in a longitudinal horizontal section,

FIG. 4 - a wedge in a longitudinal vertical section,

FIG. 5 - the claimed device in operation.

The hairpin (1) is made of a T-shape with a tail part (2) and a working part (3). The working part (3) is made flat and adjoins its middle part to the lower part of the tail part (2). The tail part (2) is made in a U-shape, adjoining with its legs (4) in the working surface (3) of the stud (1). Legs (4) in their lower part have (5) weakened strength. The wedge (6) is made in the form of two main rectangular plates (7) adjacent to each other with their same smaller sides (8) to form an angle (a) that is less than 90 °. On the other sides, the main plates (7) of the wedge (6) are connected by perpendicular longitudinal (9) and transverse (10) additional plates. In addition, in the middle between the longitudinal additional plates (9), a middle plate (11) is fixed parallel to it, passing inside the wedge cavity (6), dividing it into two equal parts. Two transverse inner plates (12) are also provided inside the wedge cavity (6), which extend parallel to the transverse additional plate (10) and divide the inner wedge cavity (6) into three equal parts. The middle plate (11) and the transverse inner plates (12) act as stiffeners. Moreover, the middle plate (11) and the transverse inner plates (12) are made thinner than the main (7) and additional plates (9, 10). The device operates as follows:

One side of the working part of the stud is “pushed” under the edge of the tile (13). The second side of the working part of the stud is covered with another tile (13). The tile thus clamps the tail of the stud. Then, a wedge (above the tile) is installed in the hole formed in the tail end of the hairpin to the desired level, thereby aligning manually or using pliers the desired level of the outer surface of the tile. Thus, the entire structure holds the entire tile in the right level until the tile adhesive dries completely. After drying of the tile adhesive, the wedge is removed from the hole of the stud, and the tail of the stud is removed from the working surface in the place of weakened strength. Thus, the wedge can be used repeatedly, because, due to its implementation in the claimed manner, during its operation does not occur its deformation, crushing, or the like. Then the seam between the tiles is covered with grout and there are no traces of additional devices used when laying the supply, while the outer surface remains perfectly flat.

The use of the claimed device when carrying out tile work allows even an unskilled worker to perform it flawlessly.
