Description

[0001] The present invention relates to a device for motorization of sliding doors.

[0002] More specifically, the invention relates to an electro-mechanical device, permitting motorization of disappearing sliding doors, that usually are operated manually, and that can be applied in the same way to doors of already existing boxes, or to new boxes.

[0003] Large development of residential building during last years, has been characterized by a housing typology with always more reduced dimensions.

[0004] Apartments have average dimensions of 50 - 60 m². For this reason, it is always more frequent the use of disappearing sliding doors.

[0005] As it is well known, different solutions of sliding doors occur on the market, that are usually open and closed manually by the user.

[0006] As already said, almost all the products existing on the market are manually open - closed, although motorized products exist that can be installed on the already installed doors.

[0007] Solutions have been recently put on the market aiming to obtain motorization of opening and closure of the sliding door wing, being meant, at least in the present specification, by the "sliding door" term, the assembly comprised of counter frame, box and sliding wing.

[0008] Motorization devices for sliding doors presently exist on the market that, to be installed, require reduction of height of doors of many centimeters.

[0009] Furthermore, said solutions require application of components from outside of the sliding door, such as for example blocking hooks, useful in case electric energy.

[0010] In any case, they are solutions requiring large modifications to the wall structure, in order to bring necessary electric connections to the door.

[0011] In view of the above, it is well evident the needing of having a motorization device for a sliding door that can be fit both on existing sliding doors and in new sliding doors.

[0012] A further object of the present invention is that of suggesting a technically simple solution.

[0013] Another object of the present invention is that of realizing a motorization device not requiring relevant implant interventions.

[0014] Another object of the present invention is that of realizing a device for motorization of disappearing sliding doors which fully disappears within the counter frame.

[0015] It is therefore specific object of the present invention a device for the motorization of sliding doors, said device comprising a door support carriage, a ratiomotor, an encoder, a pair of pulleys, respectively a driven pulley and a pulley provided with friction, a belt between said two pulleys, means for controlling the motion of the sliding door, and a section bar containing said elements.

[0016] Preferably, according to the invention, said ratiomotor is a 24 V direct current ratiomotor.

[0017] Always according to the invention, said belt is comprised of polyurethane.

[0018] Furthermore, according to the invention, said control means comprise control units, for adjustment of speed, and a control button.

[0019] Still according to the invention, said section bar is comprised of aluminum or iron, said section bar having such depth, height and length perfectly conforming to the measures of the counter frame.

[0020] The invention further relates to a method for mounting a device for motorization of sliding doors as described in the above, comprising the following steps:

• dismounting the door;
• introducing the ratiomotor within the sliding element of the support, making it sliding for about 50 cm;
• introducing the two carriages for supporting and sliding the door, making it further sliding until when the device is in a position parallel to the door sliding guide;
• fixing the same by fixing means, e.g. a screw;
• making electric connections.

[0021] The present invention will be now described, for illustrative but not limitative purposes, according to its preferred embodiments, with particular reference to the figures of the enclosed drawings, wherein:

figure 1 is a perspective view of an embodiment of a device for motorization of sliding doors according to the invention;

figure 2 is an exploded view of device of figure 1;

figure 3 shows the step of installation of the device according to the invention; and

figures 4a and 4b show operation of the door respectively with manual and motorized sliding.

[0022] Observing the figures of the enclosed drawings, and first observing figure 1, it can be observed a device according to the present invention, generically indicated by reference number 1, comprising a carriage 2, supporting the door (not shown), a ratiomotor 3, particularly a 24 V direct current ratiomotor, an encoder (not shown in the figure), a pair of pulleys 4, respectively a driven pulley and a pulley provided with friction, a belt 5, preferably comprised of polyurethane.

[0023] Furthermore, they are provided control units (not shown), for adjustment of speed, and a control button, the whole inserted within a section bar, said section bar being comprised of aluminum or iron, and having such depth, height and length perfectly conforming to the measures of the counter frame.

[0024] Observing the other figures enclosed, it can be observed that the mounting of this device is very simple.

[0025] After having dismounted the door 10, ratiomotor 3 is inserted within the sliding element of the support, making it sliding for about 50 cm.

[0026] Then the two carriages are introduced for supporting and sliding the door 10, making it further sliding until when the device is in a position parallel to the door 10 sliding guide.

[0027] The whole is fixed by a single screw. Then low tension electric connections are made, without requiring, unless wished, trace on the wall.

[0028] Obviously, in case electric power fails, it is possible opening manually the door.

[0029] As it can be observed, device 1 according to the invention perfectly conforms to the existing framework, completely disappearing from the view.

[0030] Ratiomotor can be provided on the right side or on the left side, on the basis of the structure of the sliding door on which it must be mounted.

[0031] The present invention has been described for illustrative but not limitative purposes, according to its preferred embodiments, but it is to be understood that modifications and/or changes can be introduced by those skilled in the art without departing from the relevant scope as defined in the enclosed claims.
