Abstract

A closing system (10) of a room by means of pull sliding panels, comprising a series of at least two panels (11) sliding parallel to one another from a first stacked/open position in which they are substantially superimposed frontally, to a second closed position for closing a room in which the panels (11) are moved apart from one another, and vice versa; there are comprised in said series at least one intermediate panel (11 ", 11"') and one end closing panel (11') for closing the room that precedes said at least one intermediate panel during the closing movement of the room. There are present abutments positioned in proximity of the lower edges of the panels for pulling these panels.

Description

TECHNICAL FIELD

The present invention relates to the field of doors for closing rooms inside buildings. More in particular, the invention relates to a closing system of a room by means of pull sliding panels, preferably but not exclusively of the type made of glass or crystal.
The invention also relates to a kit for assembly of the aforesaid closing system.

State of the art

For many years now there have been known systems for closing rooms that involve the use of doors formed by sliding panels, that slide parallel to one another, from a stacked position, in which the panels are all grouped together on one side of the opening for accessing the room, superimposed laterally on one another, to a closed position, in which they extend to close the opening, with small edge portions superimposed laterally on one another, have been known for many years now.
In the majority of these systems, the panels are hung from trolleys sliding on guides fixed to the ceiling or to the wall, and movement of the panels generally takes place by pulling. In practice, from the stacked position, using, for example, a handle, the user pulls the panel that will be the end closing panel of the opening of the room; during translation, this panel, by means of abutment bodies positioned at the upper trolleys, comes into contact with counter-abutment bodies present on the trolleys of the immediately contiguous panel, pulling it toward the closed position. In the case in which there are three panels, the second panel moved will be provided with abutment bodies and the third panel will be provided with counter-abutment bodies, so that during movement of the second panel the third panel is also moved. The movement for opening the room, i.e. movement of the panels toward the stacked position, takes place substantially in the opposite direction, again by pulling.
Although these systems have been known for some time, they have various problems. A first problem is linked, for example, to the footprint of the panels when they are in stacked position. In fact, in this position the abutment bodies and the counter-abutment bodies are spaced apart on the trolleys, above the panels, with a configuration that obliges the outer edges of the panels, i.e. the edges facing the closed position, to remain staggered from one another, with an evident increase in the footprint of the stacked position and reduction of the opening of the room, which increases as the number of sliding panels used increases.
Moreover, it is possible for foreign bodies to enter the spaces above the panels, between the guides, the trolleys and the abutment bodies and the counter-abutment bodies, blocking movement of the panels or causing noise; in these cases it is necessary to use a ladder to remove the protection that conceal the guides and the trolleys and eliminate the foreign bodies.
Moreover, in the prior art systems described above, the panels tend to pivot about an axis corresponding substantially to the sliding surface of the trolleys on the guides. To prevent this, there are sometimes embedded in the floor lower guides for guide elements associated with the lower edge of the panels, to constrain them to the floor and prevent pivoting; clearly, the use of a guide embedded in the floor leads to problems during installation and of maintenance, related to the possibility of foreign bodies entering this guide.
In addition, in the systems described above, the panels, due to imperfections during installation or small variations in the structure with which they are associated, can often lose their correct horizontal arrangement, so that the panels tend to move toward the stacked or closed position, even when this is not required.

Object and summary of the invention

The main object of the present invention is to solve the aforesaid problems by producing a closing system of a room by means of pull sliding panels, which is of simple construction, and a kit for the assembly of said system.
Another important object of the present invention is that of producing a closing system of a room by means of pull sliding panels that is reliable in its operation.
Yet another important object of the present invention is that of producing a closing system of a room by means of pull sliding panels that is simple to install.
One more important object of the present invention is that of producing a closing system of a room by means of pull sliding panels that overcomes or reduces possible pivoting of the panels during movement.
A further important object of the present invention is that of producing a closing system of a room by means of pull sliding panels that allows stable positioning of the panels in the operating positions thereof.
These and other objects, which will be more apparent below, are achieved with a closing system of a room by means of pull sliding panels as claimed in claim 1 set forth below, and with a kit for assembly as claimed in claim 20.
The invention relates in particular to sliding panels without a perimeter frame in which pulling devices could be concealed. The invention relates to a system provided with elements or kits to be fitted substantially on the outer surface of the panels. It is understood that these elements or kits could also be fitted to the outer surface of panels with a perimeter frame.
Therefore, according to a first aspect, the closing system of a room by means of pull sliding panels, according to the invention, comprises:

a series of at least two panels sliding parallel to one another from a first stacked/open position in which they are substantially superimposed frontally, to a second closed position for closing a room in which the panels are moved apart from one another, and vice versa; in this series there are comprised at least a first panel and a second panel, with said first end closing panel of the room that precedes said second panel during movement,
longitudinal sliding means for the panels, arranged above said panels, from which the panels are hung,
abutment elements for pulling contiguous panels, fixed in proximity of the two edges, outer and inner, at least of the first end closing panel,
at least one guiding and pulling unit fixed in proximity of the outer edge of at least said second panel, comprising
- o a portion of sliding guide for the lower edge of said first end panel, and
- o counter abutment portions for said abutment elements of said end panel,

According to preferred embodiments, the closing system of a room according to the invention comprises at least three panels; of said at least three panels there are present a last panel adapted to close the room on the opposite side thereof with respect to the first panel, and a second last panel that precedes the last panel; in proximity of the inner and outer edges of the second last panel there are associated said abutment elements for pulling contiguous panels; there being associated with said last panel at least one said guiding and pulling unit fixed in proximity of the outer edge of the last panel, which comprises a portion of sliding guide for the lower edge of the second last panel, and counter abutment portions for abutment elements of the second last panel; the system is such that in the movement from the stacked/open position to the closed position, the abutment element associated with the inner edge of the second last panel that precedes the last panel in movement, impacts against a first counter abutment portion of the guiding and pulling unit associated with the last panel that follows, pulling with it said last panel, while, in the movement from the closed position to the stacked/open position, the abutment element associated with the outer edge of the second last panel impacts against the second counter abutment portion of the guiding and pulling unit associated with the last panel, pulling this with it.
It can be said, according to preferred embodiments, that in the closing system of a room according to the invention, which comprises at least three panels, there is present at least one intermediate panel comprised between the first panel and the last panel adapted to close the room; in proximity of the inner and outer edges of this intermediate panel there are associated with said abutment elements for pulling contiguous panels; there is associated with the outer edge of said intermediate panel a said guiding and pulling unit, comprising a portion of sliding guide for the lower edge of the contiguous panel that precedes it, and counter abutment portions for abutment elements of the contiguous panel that precedes it, so that in the movement from the stacked/open position to the closed position, an abutment element, associated with the inner edge of the panel that precedes said intermediate panel, impacts against a first said counter abutment portion associated with said intermediate panel that follows, pulling with it the intermediate panel, while, in the movement from the closed position to the stacked/open position, the abutment element associated with the outer edge of the panel that precedes the intermediate panel impacts against the second counter abutment portion of the guiding and pulling unit of said intermediate panel, pulling this with it.
In the description that follows, intermediate panel can also be intended as the last panel, i.e. a panel subsequent to the first panel; therefore, in a system with two panels, intermediate panel can also be intended as the second and last panel of the system.
In general, as will be more apparent hereinafter and according to the typical configuration of sliding panel system, each panel, with the exception of the last panel (i.e. the one opposite the first panel that closes the opening of the room with respect to any other intermediate panels), pulls a respective contiguous panel both in the movement to close the room, and in the movement to stack/open the panels (in the closing movement the contiguous panel moved is pulled, while in the opening movement the contiguous panel moved is pushed).
Preferably, the abutment elements for pulling contiguous panels, and the at least one guiding and pulling unit fixed in proximity of the outer edge at least of said second panel, or of the intermediate panel, are fixed close to the lower edge of the respective panels. Purely by way of example, the abutment elements for pulling contiguous panels, and the at least one guiding and pulling unit can be designed to be fixed at a distance from the lower edge comprised between around 1/20 and 1/200 of the height of the panel to which they are fixed. It must be clear that the distance from the lower edge is fixed and cannot be varied during use; the range indicated above is a range related to the design phase of the system.
Preferably, the outer edges of the panels are substantially aligned when the panels are in said stacked position.
Advantageously, the system can comprise a guide to be fixed to the floor in which there is arranged slidingly the last panel of the series of panels, i.e. the last panel to be pulled during the opening movement.
According to preferred embodiments, the guiding and pulling unit comprises a sandwich locking portion to the outer edge of the intermediate panel; from one side of the locking portion there extends an appendage forming a said abutment element; on the side of the locking portion, opposite said appendage with respect to the panel, there is defined, at a distance from the lower edge of the panel substantially corresponding to the distance of the appendage from the lower edge, a pair of seats open in opposite directions toward the opening or closing direction of the panels, for housing a respective said appendage, in which there are defined respective counter abutment portions for the abutment elements of the panel that precedes in movement; this guiding and pulling unit comprises, on the same side of the panel in which the seats are present, the aforesaid portion of sliding guide for the panel that precedes in movement. Advantageously, the locking portion can have a distance from the lower edge of the panel at least equal to or greater than the depth of said guide portion; said guide portion is below the seats and projects laterally therefrom.
Preferably, in this guiding and pulling unit, the seats, the guide portion and at least part of the locking portion are produced in a single piece.
Preferably, the abutment elements for pulling contiguous panels, fixed in proximity of the two edges, outer and inner, of the end closing panel and of the inner edge of the at least one intermediate panel comprise a said appendage adapted to be associated with the counter abutment portions of a related guiding and pulling unit of the contiguous intermediate panel.
Advantageously, there are associated with the first panel, i.e. the end closing panel, two abutment units each comprising an abutment element; these abutment units comprise respective sandwich locking portions to the panel; preferably said locking portions comprise a plate and a counter plate arranged on opposite sides of said panel, and a screw for connection of said plate and counter plate passing through said panel.
Preferably, there are associated with at least one intermediate panel, on opposite edges, a said guiding and pulling unit fixed in proximity of the outer edge and an abutment unit comprising at least one said abutment element; the abutment unit comprises respective sandwich locking portions to the panel; preferably, the locking portions comprise a plate and a counter plate arranged on opposite sides of said sheet, and a screw for connection of said plate and counter plate passing through the panel.
Preferably, there is present a reversible coupling between the abutment element and the related counter abutment portion; preferably this reversible coupling is of the type for elastic deformation.
Advantageously, the aforesaid appendage is surrounded by an elastic ring, preferably made of rubber or the like. Advantageously, the seat in which the appendage must abut can have a concave C-shaped configuration with dimensions such as to urge the elastic ring to temporarily deform by compression during the step of inserting the appendage into said seat; this seat urges the appendage into position when it is inserted therein; the step of removal of the appendage from the seat occurs with a thrust such as to overcome the elastic deformation of the ring for removal from the seat.
According to another aspect, the invention relates to a kit for assembly of a closing system of a room by means of pull sliding panels according to one or more of the preceding embodiments, comprising at least

the aforesaid abutment elements for pulling contiguous panels, to be fixed in proximity of the two edges, outer and inner, at least of said end closing panel and/or of one intermediate panel,
said at least one guiding and pulling unit to be fixed in proximity of the outer edge of said at least one intermediate panel.

Preferably, the kit comprises, for a system that comprises a number "n" of sliding panels, "n-1" abutment units to be fixed in proximity of the inner edge of the panels, with the exclusion of the last panel "n", an abutment unit to be fixed to the outer edge of the first panel (end closing), and "n-1" guiding and pulling units to be fixed to the outer edge of the panels with the exclusion of the first panel; preferably the system is also provided with a floor guide for the last panel "n".

Detailed description of an embodiment of the invention

With reference to the aforesaid figures, a closing system of a room by means of pull sliding panels is indicated as a whole with the number 10.
In this example, the system 10 is provided with a series of three panels 11, indicated respectively with 11', 11 ", and 11'"; hereinafter, elements associated with a specific panel shall also be indicated with a corresponding number of apostrophes; when features associated with a panel are indicated without apostrophes, this means that they can concern all the panels, unless otherwise apparent from the context. These panels 11 slide parallel to one another from a first stacked position, as shown in Figs. 1, 2, 3 and 4, to a second position, for closing the opening of a room, as shown in Fig. 8 the opening for access to the room is not explicitly indicated in the figures; more generally, the "closed position of the room" will be indicated hereinafter; the jamb against which the panels abut when closed is indicated with the letter S in Figs. 7, 8 and 9.
The panels 11 are made, for example, of sheets, preferably flat and preferably of the same width, height and thickness. Width is intended as the dimension orthogonal to the vertical extension of the sheet when positioned upright, hereinafter referred to as "height". Hereinafter, the term sheet or the term panel shall be used at times to indicate the same object.
In this example, the sheets are made of glass or crystal. It is clear that in other examples these sheets can be made of any other material, for example wood, marble, resin, plastic, combinations of these, etc.
Advantageously, in preferred embodiments, in the stacked position, the sheets are superimposed frontally, with the outer edges, indicated with 12A, which are substantially aligned, as clearly visible in Fig. 3 and in Fig. 4. Therefore, alignment takes place along a line L orthogonal to the plane of the sheets or to the direction of their movement. Hereinafter, the term inner edge, indicated with 12B, is intended as the edge of the sheets, i.e. the face of the sheet related to the thickness, facing the stacked position, i.e. the edge of the sheets that during movement from the closed position to the stacked position reaches the stacked position first. The term outer edge 12A is therefore intended as the opposite edge of the sheets, i.e. the edge facing the direction of closing of the room.
Preferably, when in the stacked position, the panels are contained inside a cavity 13. In this example, the cavity 13 is formed by a single concealing wall 13A, for example formed by a static sheet fixed to the ceiling and to the floor by means of a frame 13B. The cavity 13 is therefore open on the side opposite the static sheet 13A with respect to the panels 11, and on the side relating to the area from which the panels 11 exit from this cavity.
As an example example, the area from which the sheets 11 exit from the cavity 13 coincides approximately with the plane of alignment of the outer edges 12A of the sheets, coinciding in turn with the outer edge 13C of the static sheet 13A, as shown in Fig. 4. In other embodiments, the outer edges 12A of the sheets can be inside the cavity 13, or outside the cavity.
In other embodiments, this cavity can be closed on both sides of the panels, for example by two static sheets, as shown in the example of Fig. 19. In other examples, the cavity 13 can be produced close to a structural element, a masonry wall (such as the example of Fig. 21), a plasterboard wall, etc.
Each panel is supported by at least one trolley 14 (more preferably at least two trolleys), arranged sliding on a respective track 15, for example fixed to a ceiling 16 opposite a floor 17. The panels 11 are thus hung from the trolleys 14. In practice, tracks 15 and trolleys 14 are longitudinal sliding means for the panels 11.
In the example of Fig. 1, the system is provided with a series of three panels 11. In a known manner, the system provides that from the stacked position, a first panel 11', corresponding to the one that will be the end closing panel of the room, is moved toward the closed position. This first panel 11' translates (Fig. 5), and during its translation, when it is extracted for the majority of its width from the cavity 13, by means of striker means described hereinafter, "couples" a second panel 11 ", contiguous thereto, pulling this with it (Fig. 6).
Similarly, the second panel 11 ", which is an intermediate panel in the series of panels of which the system is composed, in its translation (Fig. 6), when it is extracted for the majority of its width from the cavity 13, by means of striker means, couples the third intermediate panel 11'", pulling this with it (Fig. 7). When the third panel 11'" is also extracted for the majority of its width from of the cavity 13, the room is closed, i.e. the closed position (Fig. 8) has been reached. As already stated, hereinafter elements associated with the first panel will also be indicated with an apostrophe, elements associated with the second panel with two apostrophes, and elements associated with the third panel with three apostrophes.
Hereinafter, the second intermediate panel 11" is also defined intermediate panel that follows (or following) the end closing panel 11' during movement, or intermediate panel that precedes the third intermediate panel 11'" during movement. Therefore, the first panel 11' precedes the second intermediate panel 11". Similarly, during the closing movement, the third intermediate panel 11'" is also defined panel that follows (or following) the second intermediate panel. In practice, the panel that is pulled is a panel following the panel that pulls, while the panel that pulls is the panel that precedes the panel pulled thereby.
The aforesaid striker means, which allow pulling of a panel by the panel that precedes it during the closing movement, are provided with abutment elements 18R-19R for pulling contiguous panels, better described hereinafter, fixed in proximity of the two edges, outer 12A and inner 12B, of each panel, with the exception of the inner edge 12B'" of the last panel, i.e. the third intermediate panel 11'", clearly visible in Figs. 4 to 9.
Moreover, there are also present, for the second intermediate panel 11" and the third intermediate panel 11'", respective guiding and pulling units, numbered respectively with 20" and 20"', fixed in proximity of the respective outer edges 12A. Each unit 20 (i.e. 20" and 20'") comprises a portion of sliding guide 21 for the lower edge 12C of the panel that precedes the closing movement of the room (panel that precedes: i.e. the first end closing panel 11' in the case of the unit 20", or the second intermediate panel 11" in the case of the unit 20"'). Moreover, each unit 20 also comprises counter abutment portions 22 (clearly visible in Figs. 13 and 17) for the abutment elements 18R and 19R associated with the panels that precede in the closing movement the panel provided with the respective unit 20 (as will be more apparent below, the abutment element 19R acts by pulling during the closing movement, while the abutment element 18R acts during the opening movement).
In practice, in the movement from the stacked/open position to the closed position, the abutment element 19R' associated with the inner edge 12B' of the end closing panel 11' that precedes the second intermediate panel 11" (intermediate panel 20" to the outer edge 12A" of which the guiding and pulling unit 20" is fixed) abuts against the counter abutment portion 22 (better described below) of the unit 20", pulling this with it, and therefore pulling with it the whole second intermediate panel 11 "(figure 5, 6 and 16). With sliding of the second intermediate panel 11 ", the respective abutment element 19R" associated with the inner edge 12B" of this panel, encounters the counter abutment portion 22 of the unit 20'" fixed to the outer edge 12A'" of the third intermediate panel 11'", pulling this latter with it until the closed position (Figs. 6, 7, 8 and 17) is reached.
On the contrary, in the movement from the closed position to the stacked/open position, the abutment elements 18R associated with the outer edges of the preceding panels, impact in sequence against the second counter abutment portions 22 of the panels that follow, pulling with them the intermediate panels that follow toward the opening.
Advantageously, the system 10 can be provided with a guide 23, to be fixed to the floor 17, in which there is arranged slidingly the last panel of the series (i.e. the last panel to be pulled into the closed position during the closing movement), that is, in this example, the third intermediate panel 11'" of said series of panels. Preferably, this guide 23 is of a length that is less than the width of this latter panel 11'". Even more preferably, this guide 23 is completely contained in the cavity 13, for example aligned with its outer end 23A with the outer edge 13C of the static sheet 13A (i.e. with the edges 12A of the panels 11). In this example, the guide 23 has a U-shaped cross section.
Preferably, the guiding and pulling unit 20 (see, for example, Figs. 10, 11, 12 and 13, in which the sheet 11 is not visible) comprises a sandwich locking portion 24 to the outer edge 12A of the intermediate panel 11 to which it is fixed, formed by a plate 24A and a counter plate 24B arranged on opposite sides of the sheet 11, and a screw 24C for connection of the plate and of the counter plate, passing through this sheet. The plate 24A has a shaped part 24D adapted to abut against the outer edge 12A of the sheet 11, which also allows the unit 20 correct to maintain the correct orientation with respect to both the edges 12A and 12C.
Advantageously, in preferred embodiments, the guiding and pulling unit 20 also comprises the aforesaid abutment element 18R related to the outer edge 12A. For example, from one side of the sandwich locking portion 24 there extends an appendage that forms this abutment element 18R. For example, this appendage, also numbered with 18R for simplicity, extends from the counter plate 24B.
Preferably, on the side of the locking portion 24, opposite the appendage 18R with respect to the panel 11, there is defined, at a distance F from the lower edge 12C of the panel 11 substantially corresponding to the distance of the appendage 24 from this lower edge 12C, a pair of seats 25, open in opposite directions toward the opening or closing direction of the panels, for receiving a respective appendage 18R or 19R. At the bottom of these seats 25 there are defined respective counter abutment portions 22 for the abutment elements 18R, 19R of the panel that precedes in the closing movement.
Advantageously, the guiding and pulling unit 20 also comprises, on the same side of the panel 11 in which the seats 25 are present, the portion 21 of sliding guide for the panel that precedes in movement, as described above.
Preferably, in the guiding and pulling unit 20, the seats 25, the guide portion 21 and at least part of said locking portion, for example, the plate 24A, are produced in a single piece.
With particular reference to figure. 2, it can be noted how, preferably, the locking portion 24 has a distance D (for example measured from the lowest point of the counter plate 24B) from the lower edge 12C of the panel 11 at least equal to or greater than the depth P of the guide portion (for example measured vertically from the bottom of the guide portion to the horizontal projection of the lowest point of the same point of the locking portion 24 from which the distance D from the lower edge 12C was measured).
The guide portion 21 is lower than the seats 25 and is preferably projecting laterally therefrom (in practice, it projects laterally and downward). This guide portion 21 has, for example, a guide cavity 21 A with U-shaped cross section.
According to the description above, it is clear that there are present two guiding and pulling units 20" and 20"', fixed in proximity of the respective outer edges 12A" and 12A'" of the second intermediate panel 11" and third intermediate panel 11"' (last panel of the series to be pulled toward the closed position). It should be noted that the figures show an appendage 18R"', i.e. projecting from the third guiding and pulling unit 20"', which has no practical function, as it does not require to abut against anything, but is provided purely for aesthetic purposes and industrial convenience (besides having the practical use of serving as a threaded seat to tighten the screw 24C and lock the unit 20).
In the case in which the panels are two in number (as in Fig. 18), there will be present a single guiding and pulling unit 20", on the second intermediate panel 11" (the same reference numbers as in the preceding case are maintained); also in this case the appendage 18R" is provided purely for aesthetic purposes and industrial convenience.
In the case of more than three panels, for example five panels, as in Fig. 20., there are present four guiding and pulling units 20", 20"', 20^IV and 20^V, for four respective panels 11", 11"', 11^IV and 11^V (last panel); also in this case the appendage 18R^V is provided purely for aesthetic purposes and industrial convenience (besides having, as already mentioned, the practical use of serving as a threaded seat to tighten the screw 24C and lock the unit 20).
Generalizing, it can be said that given a number n of panels (with a minimum of two sliding panels), there will be present n-1 guiding and pulling units 20.
The abutment elements 19R are preferably in the form of appendages that project laterally from abutment units 26 fixed at the inner edges 12B of the panels (with the exclusion of the last panel to be pulled, in the case of three panels, the third intermediate panel 11"'). These appendages, also numbered with 19R for simplicity, are preferably identical to the appendages 18R. Each abutment unit 26 (see for example Figs. 14 and 15, in which the sheet 11 is not represented) has a further sandwich locking portion 24bis which comprises, similarly to the case of the guiding and pulling units 20, for example a further plate 24a and a further counter plate 24b arranged on opposite sides of the respective sheet, and a further screw 24c for connection of said plate and counter plate passing through said sheet. Also in this case, the further plate 24a has a further shaped part 24d adapted to abut against the inner edge 12A of the sheet 11. The appendage 19R projects from the further counter plate 24b.
Similarly, only for the first panel 11', there is present a further abutment unit 26bis, similar to the abutment unit 26', arranged in proximity of the outer edge 12A' of the panel, substantially at the same height and position as the abutment unit 26'.
Now, as stated, the abutment elements 18R and 19R are adapted to abut against the counter abutment portions 22 of the guiding and pulling units 20. The appendages that form the abutment elements 18R and 19R preferably have cylindrical symmetry and are surrounded by an elastic ring 27, for example an O-ring, made of rubber or other similar material. When the appendages 18R and 19R are inserted in the seats 25 and abut against the counter abutment portions 22, advantageously there is present a reversible coupling between them, so that there is a certain degree of tightness between abutment appendage and related seat 25. This reversible coupling takes place through the elastic deformation of the ring.
Advantageously, each opposed seat 25 has a concave configuration, for example C-shaped, with dimensions such as to urge the elastic ring 27 to temporarily deform by compression during the step of inserting the appendage into the seat; when the appendage is inserted into the seat, the shape of this urges this appendage to remain in position; the step of removal of the appendage from the seat takes place simply with a thrust, in the opening direction of the seat, such as to overcome the elastic deformation of the ring.
It can be noted how in Figs. 13 and 17, the two opposed seats 25 are shaped like a C without the back, i.e. the seat, on the top and on the bottom, has two opposed cusps that define the counter abutment portions 22. The space between the two cusps would correspond to back part of the C-shape seat. According to another point of view, each seat is formed by two opposed concave portions 25a, defined on the top and on the bottom, facing each other, one side of which is produced by the cusps defining the counter abutment portions 22.
As stated before, the outer edges 12A are preferably aligned with one another along L. In other embodiments, the outer edges 12A may not be aligned. For example, in certain cases, it may be useful to fix a handle to the first panel 11' and therefore the outer edge of the first panel must protrude slightly with respect to the outer edges of the other panels (which can be aligned with one another); In this case, it will be necessary to fix the abutment element 18R' at a greater distance from the outer edge 12A' with respect to the distance related to the case of alignment (i.e. a greater distance with respect to the distance of the related seat 25 from the outer edge 12A" of the second panel 11 ").
Operation of the system is as follows. With reference to the stacked/closed position, in which all the panels are aligned with their outer edge 12A on the line L (Fig. 4). The first panel 11' has the appendage 18R' of the abutment unit 26bis inserted in the seat 25 of the guiding and pulling unit 20" fixed to the second panel 11 "; similarly, the second panel 11" has the appendage 18R" projecting from its guiding and pulling unit 20" inserted in the seat 25 of the guiding and pulling unit 20'" fixed to the third panel 11'". The lower edge 12C' of the first panel 11' is inserted in the guide portion 21" of the guiding and pulling unit 20" fixed to the second panel 11 ", just as the lower edge 12C" of the second panel 11" is inserted in the guide portion 21'" of the guiding and pulling unit 20'" fixed to the third panel 11'". The lower edge 12C'" of the third and last panel 11'" is inserted in the floor guide 23.
The user starts to push the first panel 11' toward the closed position, overcoming the slight resistance for elastic deformation (viscoelastic or similar) of the ring 27 on the seat 25 of the guiding and pulling unit 20", so that the appendage 18R' of the abutment unit 26bis is removed from the seat 25. The panel 11' thus slides with its lower edge portion 12C' (Fig. 5) inside the guide portion 21" of the guiding and pulling unit 20". At a certain point, the appendage 19R' of the abutment unit 26' of the first panel 11' is inserted in the seat 25 of the guiding and pulling unit 20" of the second panel 11 ", deforming its ring 27 and abutting against the counter abutment portion 22 of the guiding and pulling unit 20".
Continuing translation of the first panel 11', the second panel 11" also starts to translate toward the closed position (Fig. 6). The second panel 11" slides with its lower edge portion 12C" inside the guide portion 21'" of the guiding and pulling unit 20"'.
At a certain point, the appendage 19R" of the guiding and pulling unit 20" of the second panel 11" is inserted in the seat 25 of the guiding and pulling unit 20'" of the third panel 11"', deforming its ring 27 and abutting against the counter abutment portion 22 of the guiding and pulling unit 20"'. Continuing translation of the first panel 11', the third panel 11"' also starts to translate toward the closed position (Fig. 7). The third panel 11'" slides with its lower edge portion 12C'" inside the floor guide 23. When the outer edge 12A' of the first panel 11' reaches the jamb S, the closed position of the room is reached. In this position, the third panel 11'" is still inside the floor guide 23 (Fig. 8).
From the closed position, the user can push the first panel 11' toward the stacked position; by doing this, the slight resistance of the seat 25 of the second guiding and pulling unit 20" on the ring 27 of the abutment element 19R' of the abutment unit 26' is overcome. At this point the first panel 11' slides in the guide portion 21" of the guiding and pulling unit 20" of the second panel 11" (still not moving) (Fig. 9) until the abutment element 18R' of the abutment unit 16bis is inserted in the seat 25 of the second guiding and pulling unit 20", abutting against the counter abutment portion 22 and thereby also translating the second panel 11". The movement continues in the same way until all the panels return inside the cavity 13.
From a practical point of view, in the case of use of abutment elements 18R-19R that reversibly couple with the counter abutment portions (for example appendages with rings 27 coupled with the seats 25), the order in which the panels detach from one another, both in the closing movement of the room, and in the opening/stacking movement, can be random (in practice depending on the force required for the panels to "detach" from one another).
For example, in the case of three panels, during opening of the room, the user can pull the first panel 11' and this, instead of immediately detaching from the second panel 11" translating with respect thereto, can immediately move the second panel (in practice, the first and the second panel still move together with the two panels not superimposed). At this point the second panel can immediately separate from the third panel 11'", with the first panel-second panel assembly translating in relation to the third panel (with this the movement of the panels then follows the movement described above, i.e. the second panel which abuts on the third panel, becoming aligned with this in stacked position and the first panel that starts to translate with respect to the second panel, returning inside the cavity), or the second panel can remain beside the third panel, while the first panel detaches from the second, moving in relation to the second-third panel assembly, as in the case described above. The same can take place in the case of the movement to close the room, i.e. during movement of the first panel, for example, the second panel can immediately move together with it (i.e. superimposed with the outer edges aligned), subsequently pulling the third panel. The "detachment" combinations of the panels can be many. In practice, the order of "detachment" of the panels can be random, although naturally all following the movement of the first panel.
In general, a limit stop (not shown in the figures) can be present for the last panel of the system, when arranged to close, together with the other panels, the room, preferably arranged on the upper track, in which the related trolley slides. This stop identifies the closed position of the last panel, beyond which it can no longer move forward. Advantageously, a limit stop (not shown in the figures) can also be present in the stacked position of the last panel, so as to prevent it from being inserted into the cavity 13 beyond this position. More in general, limit stops can be present in the related closing position of the room and stacking position for each panel of the system.
The invention also relates to a kit for assembly of a closing system of a room by means of pull sliding panels according to one or more of the possible embodiments indicated above, which comprises at least the abutment elements 18R, 19R, for pulling contiguous panels 11, to be fixed in proximity of two edges 12A and 12B, outer and inner, at least of the end closing panel 11' and/or of an intermediate panel 11' and 11".
Preferably, the kit comprises, for a system that comprises a number "n" of sliding panels, "n-1" abutment units 26 to be fixed in proximity of the inner edge 12B of the panels, with the exclusion of the last panel "n", an abutment unit 26bis to be fixed to the outer edge 12A' of the end closing panel 11', and "n-1" guiding and pulling units 20 to be fixed to the outer edge 12A of the panels with the exclusion of the first panel 11'; preferably the system is also provided with a floor guide 23 for the last panel 11ⁿ.
The system and the related kit thus described achieve the set objects. In fact, through the abutment elements positioned in the lower part of the panels, the outer edges of the panels can be maintained aligned with one another when in stacked position. Moreover, with this configuration, the risks of malfunction of the system are very low and maintenance of the system is facilitated.
Further, the panels are properly guided during their travel, eliminating the effect of pivoting about the upper track in which the trolleys from which the panels are hung slide.
In addition, the abutment method of the abutment elements and of the counter abutment portions makes it possible to ensure the stability of the positions of the panels even in the presence of small imprecisions in the horizontality of the sliding system of the panels, while at the same time minimizing the noise in movement of the panels.
It is understood that the drawings only show possible non-limiting embodiments of the invention, which can vary in form and arrangement without however departing from the scope of the concept on which the invention is based. Any reference numerals in the appended claims are provided purely for the purpose of facilitating the reading thereof in the light of the description above and of the accompanying drawings, and do not in any way limit the scope of protection.
