Definitions

• the invention relates to a sliding door or window.
• the sliding door or window according to the invention is of the type having at least two sashes of which one is a fixed sash and one is a movable sash, the sash being movable in two different trajectories, in both directions, for its opening and closing.
• the door or window has the fixed sash and the movable sash, when the door or window is closed and open, positioned offset on two opening planes engaged by the door or window.
• the door or window has the fixed sash and the movable sash on a single plane with the door or window closed, whilst the planes are doubled during the opening of the movable sash.
• This second type of sliding door or window comprises:
• a load-bearing frame having two uprights, a lower crosspiece and an upper crosspiece to define a compartment; a sash fixed to the frame to engage at least a part of the compartment defined by the frame;
• a movable sash having lower and upper movement units associated with corresponding crosspieces of the movable sash and configured for moving the sash from a closed position of the door or window, wherein the movable sash is positioned coplanar with the fixed sash for closing the compartment, to an open position of the door or window in which the movable sash is alongside the fixed sash on a plane parallel to that of the fixed sash;
• each guide comprises a first rectilinear section extending on the free portion of the crosspiece alongside the fixed sash and a second section, connected to the first section, transversal or connected in a curved fashion to the first section and ending coplanar with plane of the fixed sash on the portion of frame engaged by the movable sash.
• the movement of the movable sash according to the invention thus has two separate trajectories: the first trajectory for moving away (disengagement) or towards (engagement) the zone of the compartment to be closed substantially transversal to the plane of the movable sash and a second trajectory substantially parallel to the plane.
• the movement units comprise, carriages at the bottom associated with the lower crosspiece and equipped with at least a ball which can rotate freely about itself.
• Each ball in use, rests inside a corresponding above-mentioned guide which has a semi-circular cross section to form a hollow channel.
• the use of a ball allows a regular sliding of the movable sash along the above-mentioned two trajectories without excessive impediments during the opening and closing of the movable sash.
• the upper sliding units are, usually, protruding pins engaging the upper guides which make it possible to keep the vertical nature of the movable sash during both movement and when stationary (open and closed).
• the use over time of the guides with balls leads to wear, even if only minimal, on the two components which may result in a worsening of the sliding fluidity or even a slight movement of the position adopted during assembly of the guides or of the ball which, also in this case, reduces the sliding fluidity.
• the aim of the invention is to provide a sliding door or window which overcomes the above-mentioned drawbacks of the prior art.
• the aim of the invention is to provide a sliding door or window which can be mounted quickly and easily whilst keeping the characteristics of high fluidity of movement.
• a further aim of the invention is to provide a sliding door or window which can be regulated in terms of the sliding components in a simple and effective manner even with the sash mounted in such a way as to always maintain the fluidity of movement.
• FIG. 1 illustrates a perspective view of a sliding door or window according to the invention
• Figure 2 is an enlarged detail of Figure 1 ;
• Figures 3 and 4 illustrate, respectively, a perspective view from above and a perspective view from below of a lower carriage applied to the door or window of the above-mentioned drawings;
• Figure 5 illustrates a side cross-section view of the carriage of Figures 3 and 4;
• Figures 6 and 7 illustrate perspective views, with some parts in cross section and others cut away to better illustrate some details, of the carriage of Figures 3 to 5 in two different operating configurations relating to adjustment devices.

• the door or window 100 comprises at least one movable sash 6 having lower and upper movement units 7 associated with corresponding crosspieces 6a (horizontal) of the movable sash 6 and configured for moving the movable sash 6 from a closed position of the door or window 100 ( Figure 1 ), wherein the movable sash 6 is positioned coplanar with the fixed sash 5 for closing the compartment, to an open position of the door or window 100 in which the movable sash 6 is alongside the fixed sash 5 on a plane parallel to that of the fixed sash 5 (position not illustrated here).
• the door or window 100 also comprises at least one lower guide 8 and a upper guide made, respectively, on the horizontal planes 3a and 4a of the upper and lower crosspieces 3, 4 of the frame 1 and engaged by the movement units 7 of the movable sash 6.

• the lower movement unit 7 may be adjusted in height through the modification of the position of the ball 9 (in contact with the guide 8) in such a way as to move the first box-shaped body 10 and the sash 6 towards or away from the guide 8 (for example, to improve the position or the alignment of the sash 6 relative to the frame 1 ).
• the lower movement unit 7 comprises a device 24 for longitudinal adjustment of the ball 9, that is, along an axis X parallel to the lower crosspiece 6a of the movable sash 6, which is able to modify the position of the ball 9 relative to the upright 2 of the frame 1.
• the lower movement unit 7 may be adjusted longitudinally through the modification of the position of the ball 9 (in contact with the guide 8) in such a way as to move the ball towards / away from the upright 2 of the frame 1 (for example, to correctly centre the position of the ball in the guide 8).
• the wheel with a spherical or ball shape 9 is composed of a ball partly contained in a cylindrical cell 9a inside of which there can be groups of recirculation balls.
• the lower guide 8 has a hollow cross-section with a semi-curved shape in such a way as to partly house, in use, a portion of the wheel with a spherical or ball shape 9.
• the upper movement units can be of the same type as the lower movement units described above (and are therefore not described further).
• the upper guides may also be structured in a similar way to the guides lower 8.
