REVOLVING PLATFORMS SYSTEM FOR HOUSEHOLD APPLIANCES

Abstract

The present invention relates to a system of rotating platforms for household appliances adaptable to various types of enclosures. The system allows easy access and manipulation without any obstruction to all the objects stored in the enclosure, due to a spin effect of the plates or platforms achieved by a radial impulse applied at its periphery by a drive power source supplemented with an arrangement of removable static shelves by means which are connected with mounting mechanisms present in the walls of the recite, in such a position that manages to take advantage of the internal space of the enclosure that is not occupied by the cylindrical volume of the platform system and functions as a passive mechanism of security, support and balance for the objects stored in the enclosure and that are supported by the platform.

Claims

A system of rotating platforms of household appliances comprising: a rotation shaft which is fixed in a rear inner wall of a container; at least one notch located on said rotation shaft; a bearing housed in each one of the at least one notch; a circular platform located on each one of the at least one notch, the circular platform including edges that lock the platform in the bearing and serve as a barrier to avoid spills of liquids that could be present in the platform; a support located on lateral walls of the container, each support including a conventional bearing, when the circular platform rotates, the conventional bearing allows objects on the platform to be stabilized; at least one projection located on the lateral walls of the container, the at least one projection are located at different heights than the platforms; at first rear projection and a second rear projection, the first and second rear projections have shape of a semicircle which coincides with a circular shape of the circular platforms and serves as a guide for the objects that rotate; wherein all of the circular platforms converge vertically concentrically; and wherein when an user places the objects on the circular platform, each circular platform rotates the object is transported to a section of the circular platform closest to the shaft.

2. The system according to claim 1, wherein at one end of the shaft a conventional motor is coupled to impart a rotation to the shaft which is toothed at least at the height of each platform, in each platform, the edges are toothed to form a rack which makes the turn of the platform, when the motor rotates the shaft.

3. The system according to claim 2, wherein the racks of the platforms make contact with a pinion fixed to the projection of the shaft and in turn, said pinion makes contact with the shaft which it is toothed and where the pinion is conventionally damped.

4. The system according to claim 1, wherein the conventional ball bearings are replaced by rollers mounted on the shaft or conventional pivots.

5. The system according to claim 1, wherein the supports are replaced by channels serving as conventional guides through which a lower peripheral notch of the platform.

6. The system according to claim 1, further including a retention device selected from the group consisting of hooks, locks, notches, and projections.

7. The system according to claim 1, wherein the platforms passing through the walls of the container includes an adjusting mechanisms to adjust the heights of the platforms.

8. The system according to claim 1, wherein the lateral supports includes an adjustment mechanism.

9. The system according to claim 1, further including a manual, an automatic or a hybrid mechanisms for regulating the energy supplied to the shaft.

10. The system according to claim 1, further including a mechanism for regulating the energy being supplied to the shaft, the mechanism for regulating the energy includes a logic processing unit to manipulate the shaft.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The rotary platforms system for household appliances comprises a shaft 1 which is fixed in the rear inner wall of a conventional container A (preferably prismatic) in said shaft 1 is at least one notch 2 where at least one bearing element 3, in said notches 2 there is introduced into each of them a circular platform 4, with edges 5 which lock the platform 4 in the bearing 3 and serve as a barrier to prevent spills of liquids which could be present on the platform 4; on the side walls of the container in accordance with the height of each platform, in each of them is a support 6 with a conventional bearing 7 where the platform 4 is seated, which when rotated allows the objects placed on it to be stabilized, and arranged in such a way that the platforms 4 coincide vertically concentrically; when the user places some objects on the platform 4 it can rotate in such a way that the placed object is transported to the part closest to the shaft 1, in the walls of the container A there are in each one of the corners a projection 8 which are at different heights than the platforms 4, preferably in the middle of the length that separates them, between each two of them; first and foremost the projections 8 serve as shelves for objects to be placed by the corners of the container A as they are flat, but the two rear projections 8a and 8b form a semicircle which coincides with the dimensions of the platforms 4 and serves as a guide for the objects rotating in them, in such a way as to prevent said objects from falling or losing their vertical position to the rotating movement of the platforms 4; the two above projections only serve as front guides as they have the curved shape of the platform 4 but are interrupted in the part closest to the access door to the container A, in order to allow the user to remove the objects that he wishes;

[0020] A first variant at one end of the shaft 1, a conventional motor 9 is coupled to impart rotation to the shaft 1 which is toothed at least at the height of each platform and, on each platform 4 the edges 5 are toothed to form a rack 10 which performs the rotation of the platform 4, when the motor rotates the shaft 1;

[0021] A second variant is that the racks 10 of the platforms 4 make contact with a pinion 11, fixed on the projection of the shaft 1 and in turn, said pinion 11 makes contact with the shaft 1 which is toothed and where the pinion 11 is conventionally damped;

[0022] The side supports 6 having a bearing, preferably conventional ball bearings, which can be changed by cylinders 12 mounted on conventional shafts or pivots where the platforms 4 rest;

[0023] The lateral supports 6 instead of rolling bearings may be replaced by channels 13 serving as conventional guides through which a lower peripheral notch of the platform 4 is passed;

[0024] All systems previously described may have retention means (eg, hooks, locks, notches, protrusions, etc.) to make them removable;

[0025] The platforms 4 when passing through the walls of the container A may have conventional mechanisms for adjusting the heights of the platforms 4;

[0026] The side supports 6 may have the adjustment mechanisms of the platforms 4 instead of the platforms having them;

[0027] The systems described above, may have mechanisms to regulate the energy that is provided to the shaft 1 manual, automatic or hybrid.

[0028] The systems described above may have mechanisms to regulate the energy provided to the shaft 1, it may come from a logical processing unit that manipulates that one, either by means of an application housed therein, or by a laser beam or By remote connection.

[0029] Having sufficiently described my invention, what I consider as a novelty and therefore claim of my exclusive property is contained in the following claims:
