Abstract:
A shade structure comprising a horizontal box that is open in a lower region and comprises within it a motorized roller with a shade associated therewith, cooperating with optional guides, and at least one bactericidal lamp.

Description:
[0001]    The present invention relates to a shade structure. 
       BACKGROUND OF THE INVENTION 
       [0002]    Nowadays it is known to provide shades that can for example be at one end slideably associated with a pole in order to be able to make them slide transversely for example to a window, or they can be wound at a motorized roller that enables automatic descent and ascent. 
         [0003]    A problem that nowadays is found in the known art consists of the scant hygiene of shades, which periodically have to be taken down in order to be subjected to washing and then put back up in place. 
         [0004]    Furthermore it has been found to be impossible to use conventional shades in particular environments, such as for example hospitals or clinics or medical studies or gyms, given that, in addition to having dust deposited on them, they become fertile ground for the proliferation of bacteria. 
       SUMMARY OF THE INVENTION 
       [0005]    The aim of the present application is therefore to solve the above mentioned technical problems, by eliminating the drawbacks in the cited known art and hence providing a shade that can be employed even in special environments in which a high degree of sanitary hygiene is required. 
         [0006]    Within this aim, an object of the invention is to provide a shade whose use can be protracted over time, thus dispensing with the need to carry out continual and periodic washing of the shade proper. 
         [0007]    Another object of the invention is to provide an invention that makes it possible to maintain the shade, even if not used, in conditions of utmost sanitary hygiene. 
         [0008]    Another object is to provide an invention that is structurally simple and low cost and can be made with the usual conventional plants. 
         [0009]    This aim and these and other objects which will become better apparent hereinafter are achieved by a shade structure, characterized in that it comprises a horizontal box that is open in a lower region and comprises within it a motorized roller with a shade associated therewith, cooperating with optional guides, and at least one bactericidal lamp.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0016]    In the embodiments illustrated, individual characteristics shown in relation to specific examples may in reality be interchanged with other, different characteristics, existing in other embodiments. 
         [0017]    With reference to the figures, the reference numeral  1  generally designates a shade structure that is constituted by a horizontal box  2 , made of metal or of plastic material or of a composite material, which preferably has a transverse cross-section that is polygonal in plan, preferably square. 
         [0018]    The box  2  has open ends  3   a,    3   b  which can be closed by way of adapted covers  4   a,    4   b;  moreover, an opening  5  is also present at a central region of the underside  6 . 
         [0019]    The opening  5  is partially closed by a pair of brushes  7   a,    7   b  which are arranged mutually opposite so as to allow the passage between them of a shade  8 . 
         [0020]    The shade is advantageously made with a fire-retardant fabric that can also be optionally chemically treated to close the fibers and make it water-repellent so as to prevent dirt from penetrating inside it. 
         [0021]    Advantageously the shade  8  has a weight that is variable between 250-300 g/m 2 . 
         [0022]    The function of the pair of brushes  7   a,    7   b  is to keep out dust. 
         [0023]    Inside the box  2  a roller  9  is provided, which is motorized and advantageously arranged in a region that lies above and offset with respect to the pair of brushes  7   a,    7   b.    
         [0024]    The roller  9  is advantageously constituted by an aluminum tube and is moved by way of an adapted axial motor, optionally removable. 
         [0025]    The shade  8  is wound around the roller  9  and its end  10  is advantageously associated with a counterweight  11 . 
         [0026]    In the intermediate region between the roller  9  and the pair of brushes  7   a,    7   b,  a pair of guides  12   a,    12   b  is advantageously arranged, between which the shade  8  is made to slide. 
         [0027]    The function of the pair of guides  12   a,    12   b  is to guide the correct positioning of the shade  8  at the underlying opening  5 . 
         [0028]    Arranged inside the box  2  a pair of bactericidal lamps  13   a,    13   b  are provided, which are arranged mutually opposite in a region that is adjacent to the underside  6  of the box  2 . 
         [0029]    Advantageously the pair of bactericidal lamps  13   a,    13   b  is arranged in a region underlying the pair of guides  12   a  and  12   b,  such that the shade  8  is positioned between them in a condition substantially perpendicular to the axis of the pair of lamps. 
         [0030]    The pair of bactericidal lamps  13   a,    13   b  is preferably of the type with UV-C rays, for example the UV DIRECT E75H-H model of the Light Progress company, which disinfects the fabric. 
         [0031]    Advantageously the pair of bactericidal lamps  13   a,    13   b  is activated together with the motor of the roller  9  while it raises and lowers the shade  8 . 
         [0032]    Another function of the pair of brushes  7   a,    7   b  is to prevent the rays of the lamps from emanating outside the box  2 . 
         [0033]    Also advantageously present is a lapsed time meter  14  which is arranged on the front surface  15  of the box  2 . 
         [0034]    Also advantageously present, again on the front surface  15 , is an on/off indicator  16  the function of which is to display whether the lamps are in operation. 
         [0035]    Thus it has been found that the invention fully achieves the intended aim and objects, a shade structure having been obtained which can also be used in special environments in which a high level of sanitary hygiene is required, the shade being sanitized at each use and kept in the box when not in use. 
         [0036]    Obviously the materials used as well as the dimensions of the individual components of the invention may be more relevant according to specific requirements. 
         [0037]    Thus, for example,  FIG. 5  shows a solution in which the shade structure  101  is constituted by a horizontal box  102  which is, in a transverse cross-section, teardrop-shaped or triangular with the vertex  117  rounded and directed downwardly. An opening  105  is defined at the vertex  117 . 
         [0038]    Inside the box  102  a roller  109  is provided, which is motorized and advantageously arranged in a region that lies above and offset with respect to the vertex  117 . 
         [0039]    The shade  108  is wound around the roller  109  and its end  110  is advantageously associated with a counterweight  111  that acts, inside the box  102 , in axial alignment with the opening  105 . 
         [0040]    Contiguous with the opening  105  a pair of guides  112   a,    112   b  are provided, which are arranged mutually parallel in the direction of the interior of the box  102  so as to define a substantially S-shaped labyrinth through which the shade  108  slides. 
         [0041]    The function of the pair of guides  112   a,    112   b  is to guide the correct positioning of the shade  108  at the underlying opening  105  and to prevent the light from emanating outside the box  102 . 
         [0042]    Arranged inside the box  102  a pair of bactericidal lamps  113   a,    113   b  are provided, which are arranged mutually opposite in a region that is adjacent to the vertex  117  of the box  102 . 
         [0043]    The characteristics indicated above as advantageous, convenient or similar, may also be missing or be substituted by equivalent characteristics.
