Abstract

In a device (100) for smoothing and / or trowelling and / or for rubbing putties or putties, comprising a smoothing and / or putty plate (1) and a handle connected to the smoothing and / or putty plate (1) (2), wherein the smoothing and / or putty plate (1) consists of metal, should be achieved that it has a long life and is also easy to clean. This is achieved by arranging a corrosion protection layer (K) on at least one smoothing and / or putty side (3) of the smoothing and / or putty plate (1).

Description

Technical area

The invention relates to a device according to claim 1.

Such tools, in particular smoothing trowels are used in construction to plaster walls with a plaster or apply other materials on other surfaces.

State of the art

A trowel of the type mentioned is out DE 29922317 U1 known.

The trowel essentially consists of a handle and a smoothing plate made of metal. For reasons of cost, the screed plate is made of a material that undergoes corrosion over time, so that the service life of such a scraper is limited.

In order not to unnecessarily shorten the life of the trowel, it is important to clean the underside of the trowel regularly, before the mass adhering to the trowel bottom has dried completely.

task

The invention has for its object to provide a device for smoothing according to the preamble of claim 1, which has a long service life and is also easy to clean.

Solution and advantages

This object is achieved by a device having the features specified in the characterizing part of claim 1 in conjunction with its generic features.

The layer according to the invention not only achieves better corrosion protection, but there is also the advantage that the tool is easier to clean. A cleaning is easy even with slightly dried putty.

Also plastering, especially with fine plaster, can be performed much better.

In addition, the corrosion protection layer may have a more abrasion-resistant property than the smoothing or putty plate, which leads to a higher wear resistance.

Further advantageous embodiments of the invention are characterized in the subclaims.

In an advantageous development of the hand-held tool according to the invention, it is provided that the anticorrosive layer is arranged on a single smoothing and / or spatula plate side, namely a smoothing and / or leveling surface of the spatula. This has the advantage, on the one hand, of low production costs and, on the other hand, of no structural change to e.g. a trowel plate top must be performed. On the trowel plate top namely a mounting flange is attached, which is connected to the handle.

Alternatively, both sides of the plate can be coated so that double-sided corrosion protection is provided. However, this may require a constructive change in the form of an intermediate plate, since the mounting flange can not be easily connected directly to the coated plate. In this solution, therefore, the anticorrosion layer is disposed on both smoothing and / or Spachtelplattenseiten, wherein between an attachment side of the smoothing and / or Spachtelplatte and connected to the handle mounting flange, an intermediate plate is arranged. An easier cleaning of the top of the screed plate is thus possible.

In a further advantageous embodiment of the invention, the corrosion protection layer is also arranged on edges of the smoothing and / or putty plate. This is very advantageous, since the edges are worked particularly intensively.

A particularly preferred embodiment of the invention is characterized in that the corrosion protection layer is designed as a scratch-resistant coating. This provides significantly less abrasion, which improves wear resistance and increases tool life.

It is particularly advantageous if the corrosion protection layer has a smoother surface structure than the smoothing and / or putty side of the screed plate lying below it. As a result, fine plaster can be applied much smoother, which under certain circumstances can spare experienced sanders additional grinding operations with a grinding machine.

In a further advantageous embodiment of the invention, the corrosion protection layer is designed as a hard chrome coating. Hard chrome has the desired strength and is particularly resistant to corrosion.

Alternatively, the anticorrosive layer can also be designed as a titanium or titanium nitride coating. Titanium has the characteristic of being particularly light and firm.

An optimum compromise between manufacturing costs on the one hand and resistance to wear on the other hand arises when the corrosion protection layer has a thickness of 0.01 mm to 0.1 mm.

Particularly suitable is the invention for smoothing trowels, spatulas, surface spatulas, doctoring. Painters and the like.

embodiment

An embodiment will be explained in more detail with reference to the drawings, wherein further advantageous developments of the invention and advantages thereof are described.

Show it:

1 a perspective view of a smoothing trowel according to the invention,

2 a sectional view of the trowel,

3 a sectional view of an alternative embodiment of the trowel, and

4 another illustration of the trowel.

1 shows a device 100 for smoothing cleaning compounds and a smoothing trowel. The trowel includes a smoothing plate 1 and one with the screed plate 1 connected handle 2 , The screed plate 1 is made of metal. The handle can be made of cork or plastic.

At least on a smooth side 3 or smoothing plate side, on which an arrow shows, a corrosion protection layer K is arranged. This page is the work page or includes the work area. The corrosion protection layer K is drawn for better perception as a thick line. The thickness is only 0.1 mm to 0.01 mm.

The working surface opposite side is a mounting side 4 for the handle 2 , Furthermore, the device 100 with a handle 2 and the screed plate 1 on the attachment side 4 connecting support element 5 provided in the 2 and 3 is shown cut. The support element 5 has a mounting flange 6 for fixing the screed plate 1 and has a handle attachment portion 7 on.

The mounting flange 6 has a plurality of openings or holes 8th on, in each case at the screed plate, like 2 shows protruding mounting bolts 9 purely project. Every bolt 9 is according to a first embodiment, on the one hand directly fixed to the smoothing plate 1 connected and on the other hand by a press connection directly to the mounting flange 6 connected, like 2 illustrated.

2 shows an embodiment in which the corrosion protection layer K on a single smooth side 3 namely a Glättplattenunterseite is arranged.

Alternatively, like 3 illustrates the corrosion protection layer K on both screed side 3 . 4 be arranged, being between the attachment side 4 the screed plate 1 and that with the handle 2 connected mounting flange 6 an intermediate element, namely an intermediate plate 10 , is arranged. The bolt 9 is in this case directly with the intermediate plate 10 connected, with the intermediate plate 10 directly at the screed plate 1 connected is.

The corrosion protection layer K is according to both embodiments also on edges 11 arranged the screed plate.

Furthermore, the corrosion protection layer K is designed as a scratch-resistant coating.

The anticorrosion layer K also has a smoother surface texture than the underlying smooth side 3 , as 4 represents, wherein the thickness ratio of smoothing plate 1 and anti-corrosion layer K in the drawing is not to scale.

The corrosion protection layer K can be designed as a hard chromium coating, as a titanium or titanium nitride coating or from another suitable coating with the corresponding hardness and corrosion protection properties.

The invention is not limited to these examples. Thus, the tool can also be a spatula or surface spatula, doctor blade, painter's spatula or another suitable for applying and polishing plasters and putties hand tool. Instead of a hard chromium coating process or titanium nitride coating process, comparable coating processes are also suitable.

Also, the attachment must be by handgrip 2 and screed plate 1 not, as stated, with a mounting flange 6 and several bolts 9 be accomplished. This attachment can be achieved with almost all methods known in the art.

Also, in a one-sided coating, ie only coating the work surface, such as 2 shows, between the attachment side 4 the smoothing and / or putty plate 1 and that with the handle 2 connected mounting flange 6 an intermediate element, in particular an intermediate plate 10 be arranged.
