Description

TECHNICAL AREA

The invention lies in the technical field of tooling and more precisely in precision cutting using a cutting tool comprising a rotary cutting disc such as a grinder, a grinder or a circular saw. portable.

The present invention will in particular be intended to facilitate the cutting of tiles or parquet, this application not being limiting, however, and the assembly constituted by the cutting guide and the tool can be used in many other applications requiring precision of important cut.

PRIOR ART

When cutting tiles, the tiler can use either a fixed installation, for example a table saw, or a portable tool such as a grinder. In the case of fixed installations, the cutting disc is fixed on the table while the tiling is guided in translation, therefore making a straight cut is relatively easy, even carried out by non-professionals.

When the tiler uses a portable tool, the cutting is not guided and given the weight of the tool, the hardness and dimensions of the tiling, the vibrations generated by the cutting or the lack of stability of the assembly , it is very difficult to make a straight cut.

In the event of a lack of precision in the cutting, it is necessary to replace the tiling, especially since tiling with assembly with fine joints or with edge jointing is more and more frequent and requires increased precision.

The object of the present invention is to propose a cutting guide for a cutting tool comprising a cutting disc making it possible to facilitate the cutting of a tile or a floorboard.

OBJECT OF THE INVENTION

A first aim of the present invention is to solve all or part of the technical problems linked to the above-mentioned prior art.

Another object of the present invention is to provide a cutting guide which can be positioned quickly and reliably on the cutting tools on the market.

Another object of the present invention is to provide a cutting guide making it possible to precisely adjust the distance between the guide edge and the cutting disc.

Another object of the present invention is to provide a cutting guide which can be mounted and dismounted on the cutting tool manually without tools.

SUMMARY OF THE INVENTION

The present invention relates to an adjustable cutting guide for a cutting tool comprising a rotary cutting disc and such that, according to the invention, the guide comprises a main body and a secondary body equipped with a guide edge, said main body comprising locking means capable of securing the main body to the cutting tool and means for receiving the secondary body for sliding the secondary body in the main body allowing movement of the guide edge parallel to the plane containing the cutting disc.

The present invention also aims to protect a cutting device comprising a rotary cutting disc equipped with an adjustable cutting guide

DEFINITIONS

BRIEF DESCRIPTION OF THE FIGURES

The present invention will be better understood on reading a detailed example of embodiment with reference to the appended figures, provided by way of nonlimiting example, among which:

- Figure 1 shows a schematic embodiment of a cutting guide, according to the invention, placed on a cutting tool

FIG. 2 represents in diagrammatic and perspective view a cutting guide alone,

FIG. 3 represents in diagrammatic view a detail of embodiment of the cutting guide,

- Figure 4 shows in schematic and perspective view a cutting guide / tool assembly in the adjustment position on a tile to be cut.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, there is shown an adjustable cutting guide 1, this cutting guide 1 is positioned on a cutting tool 2 comprising a rotary cutting disc 3.

Advantageously, this cutting guide is made of a metallic material and in particular steel. However, the cutting guide 1 may also be produced in other materials within the reach of the skilled person and in particular in a rigid plastic material.

This cutting guide 1 essentially comprises a main body 4 and a secondary body 5 equipped with a guide edge 6.

The main body 4 will allow both securing to the cutting tool 2 and adjusting the position of the secondary body 5.

To this end, said main body 4 comprises locking means 7 capable of securing the main body 4 to the cutting tool 2 and means 8 for receiving the secondary body 5 for the sliding of the secondary body 5 in the main body 4 .

As shown in Figure 1 the guide edge 6 is placed in a plane substantially parallel to the plane containing the cutting disc, the sliding of the secondary body 5 allows movement of the guide edge 6 parallel to the plane containing the cutting disc.

Referring this time more particularly to FIG. 2, the cutting guide 1 detached from the cutting tool is shown, the main body 4 comprises a first 9a and a second part 9b and spacing means 10.

The spacing means 10 between the two parts make it possible to vary the spacing between the wings 11, 12 of the two parts, respectively 9a and 9b, substantially of angled shape, and allowing attachment to the sides 13 of the cutting tool. 2.

Advantageously and as illustrated in FIG. 2, the spacing means 10 comprise two tabs 14 formed on the edges of one of the two parts defining a groove for the spacing of the second part.

Referring again to FIG. 1, it can be seen that the locking means 7 comprise, at the level of the first part 9a, a tightening wheel 15 cooperating with a thread 16 in the cutting tool 2.

This tapping is generally present on each side 13 of the cutting tools 2 making it possible to screw a grip handle on one of the two sides 13 of the tool 2 according to the user and mainly if the latter is right-handed or left-handed. The second tapping being free is used for fixing by the locking means 7.

Advantageously, the locking means 7 as shown in the appended figures are fixed to each side 13 of the cutting tool 2.

To this end, the locking means 7 comprise at the second part 9b a passage 17, and for example a notch or an orifice, able to allow the maintenance of the second part 9b between the side 13 of the tool and its grip 18.

Referring this time to FIG. 3 showing in schematic view a detail of embodiment of the cutting guide 1.

The main body 4 comprises, as indicated above, means 8 for receiving the secondary body 5.

Advantageously, the receiving means comprise a profile 19 at the level of the main body 4, the internal profile 20 of which corresponds to the external profile of a rod 21 of the secondary body 5. The rod 21 slides in the profile 19, and means of blocking 22 of the position of the rod 21 relative to the profile 19.

Preferably, the locking means 22 comprise a tightening button 23 allowing continuous adjustment of the spacing between the guide edge 6 and the cutting disc 3.

To this end, the user unscrews the tightening button 23 and then slides the rod 21 to the desired position. Once the rod 21 is positioned, the user tightens the tightening button 23 which bears on the profile 19 and the rod 21 comes to prevent their translation.

In order to precisely adjust the distance between the guide edge 6 and the cutting disc 3, the main body 4 comprises a rule 24 cooperating with a pointer 25 on the secondary body 5.

Referring this time to Figure 4 showing in schematic view and in perspective a cutting guide / tool assembly in the adjustment position on a tiling to be cut, it can be seen that the guide edge 6 is placed against the edge of the tiling to be cut . Once positioned, the guide edge allows the disc 3 of the tool to be placed parallel to the edge of the tiling. By holding the guide edge 6 against the edge and translating it along the edge, the user can very precisely cut a strip of tiling.

The cutting device comprising a rotary cutting disc equipped with an adjustable cutting guide as mentioned above therefore makes it possible to easily carry out precision cutting work like table cutting devices equipped with guide means.

Of course, other characteristics of the invention could also have been envisaged without departing from the scope of the invention defined by the claims below.
