Description

Portable electric tile cutter from standard drive with motor.

The present invention relates to a machine tile cutter, in particular a cutter portable motorized tiles.

As is known, in the field of machines for cut mosaic tiles, they are widely used small Simple and economical hand tools.

An example of these tile cutters is represented in document DE 296 06 832 U1.

In general, a mosaic cutter is composed of a splint or wooden plate, which constitutes the support plane of the tile to be cut, provided with a head and a rear profile in which the end of a bar is fastened Longitudinal lock and guide. The longitudinal bar has normally the double function of guiding the cutting tool and of block or fix on the plate the tile under that.

These devices have been successful thanks to their simplicity and portable character, although they have never been useful attempts to drive them with motor, even if it could be advantageous in many applications in which it is required a robust and fast cutting action.

The motor drive of these devices with the traditional solution of the known technique is not effective, since It carries volumes, weights and costs that do not make the Appliance for users.

The Applicant, therefore, has imposed the task of overcoming these inconveniences, with the purpose of supplying an electric tile cutter, anyway Lightweight, portable and economical. The individual solution of the Applicant arises from the original intuition of getting a way to  motor drive (which is the most expensive component and bulky system) that is already normally available at user of the tile cutter, i.e. tiles. This universal motor drive can consist of in the usual motor of an appliance, as well as an electric drill or other.

Therefore, according to the invention, the solution sought is identified in a tile cutter as has described in its essential features in the main claim attached, that is a tile cutter provided with a guide assembly on which a slider is mounted tool holder that rotatably supports a cutting blade driven through a tree that ends in a universal mandrel, for example with M14 threaded bushing.

Other aspects of the invention are described in the subordinate claims.

Other features and advantages of the device according to the invention they will be evident in any way from the detailed description that follows in a preferred way of realization thereof, given by way of example and illustrated in the attached drawings, in which:

Figure 1 is a perspective view of the front part of the apparatus of the invention with the tool lowered and without motor;

Figure 2 is a perspective view of the apparatus of the invention with the utensil raised and provided with engine;

Figure 3 is a perspective view of the left rear part of the apparatus of figure 2; Y

Figure 4 is a detail view of the tool holder coupled to an engine correspondent.

A tile cutter, in particular a mosaic cutter (figure 1), it is composed, so in itself known, from a splint or base plate 1, from which they rise two pairs of ends 2a-2d, between which are arranged two tubes 3a and 3b parallel to each other and longitudinal with respect to the desired cutting line.

On the base 1 are also arranged a square of measurement, indicated generically with 4, and a bar Longitudinal lock and guide 5.

The latter consists of a flat bar, at along which there is a through groove 5a. That it is held at the ends by means of fixing knobs 6, between which can be compressed against base 1. Bar 5 is intended to hold a tile on the base, in particular a tile mosaic tile 7, guiding at the same time a utensil or cutting tool on the same tile through of the slit 5a.

According to the invention, in the two tubes 3a and 3b a carriage is slidably mounted tool holder 100, which supports rotating one blade 101, and the corresponding protection box 102.

The tool carriage is preferably it comprises a support body 104, mounted of tilting way on a rod 105 that carries at its end two sliding sleeves 106a and 106b slidably mounted in tubes 3a and 3b, respectively.

The support body 104 has a shape essentially of L, at whose end a cube 107 is arranged in which is coupled a drive shaft (not shown). A tree end is provided with a threaded mandrel 108 of type universal, for example M14, while at the opposite end (not visible) the circular cutting blade 101 is mounted in solidarity. Cube 107 also covers box 102 covering the blade, on which a handle 109 is arranged for the held by the user's hand.

Since the support body 104 can tilt over rod 105, the complete set tool holder 100 can take a position raised (figures 2 and 3), in which the circular blade is at the view and is inoperative, and a lowered position (figures 1 and 4), in which the blade is in an operational position, introduced in the slit 5a and in contact with the tile located below and that It is going to be cut.

Thanks to the sliding assembly on the tubes 106a and 106b, the blade 101 can be driven, acting on the handle 109, forward and downward along base 1 to make the tile cut.

Thanks to the configuration according to the invention, the motor drive component can be easily coupled to the universal mandrel 108, according to the user's own need. For example, as illustrated in Figure 4, the mandrel 108 is You can attach the motor of a portable device F.

Finally, according to a form of execution preferred, the plate 1 has a through groove below the locking bar 5. Below the base 1, in correspondence with this through groove 5, a channel of collection of waste and work waste (not shown). The channel it is open up and closed at one end; for the other end (for example, later), the channel ends in a suction nozzle 200, to which a vacuum cleaner that collects all work waste, to avoid it that disperse in the surrounding environment.

As you can see, the goals that the Applicant has been proposed have been achieved perfectly with the tile cutter of the invention. In fact, thanks to the concrete configuration, with tool holder Sliding and universal connection, the device maintains a essential simplicity as well as acquisition economy and at the same time, it can be driven with motor easily by resorting to a Universal and portable engine system, available to the user Even for other applications.

It is also intended that the invention does not remain limited to the particular configuration described above and illustrated, which constitutes only a non-limiting example of field of the invention, but numerous variants are possible, all within the reach of a branch technician, without going out for this within the scope of the invention itself.

In particular, although the description has always made reference to a mosaic cutter, it is intended that a tile cutter can also be conceived according to The teachings offered.
