DESCRIPTION

[0001]The present invention relates to a system of packable movable panels, in particular glass panels. [0002]Packable movable panel systems are known from the prior art, which allow to close a room, e.g. a veranda, when desired, e.g. in bad weather, so that it can be used as an additional sheltered space. On the other hand, in good weather conditions, such a space can be used as an outdoor environment by means of such packable movable panel systems, by arranging said panels in a packaged configuration .

[0003]In the known embodiments, the panels, preferably made of glass, are large in size, so as to allow effective lighting of the space even with the panels in the closed position.

[0004]Moving the large glass panels is not easy. Indeed, there are special guides and appropriate sliding means suitable to operate with them to move the panels. [0005]It is also apparent that large glass panels require specific guide solutions, and especially carriage devices suitable to support the glass panel slidingly in an effective and reliable manner, especially over time.

[0006]In particular, the larger the size of the glass panels the more the carriage device becomes a critical component of the movable panel system.

[0007]It is the object of the present invention to create a system with packable movable panels that ensures an efficient and reliable movement of glass panels over time.

[0008]Such an object is achieved by a packable movable panel system according to claim 1 below.

[0023]As mentioned, at least one glass panel 3 which extends planarly on an imaginary panel plane is comprised in the movable panel system 1 of the present invention. [0024]Said glass panel 3 comprises a first edge 31, preferably upper, and a second edge 32, preferably lower. [0025]According to the present invention, the movable panel system 1 comprises at least one carriage device 5 which slidingly supports the glass panel 3 onto the guide 2.

[0026]According to the present invention, said carriage device 5 is engaged (preferably mounted, preferably fixed) on a respective edge of the panel. [0027]Preferably, said carriage device 5 is engaged

(preferably mounted, preferably fixed) with said second edge 32.

[0028]Preferably, said carriage device 5 is also engaged (preferably mounted on, preferably fixed to) with said first edge 31.

[0030]Preferably, in a preferred embodiment, for each glass panel 3 there are two carriage devices 5 positioned respectively at the two longitudinal ends also of the first edge 31.

[0031]According to the present invention, the carriage device 5 comprises a carriage body 6 engaged with the glass panel 3. Indeed, the carriage body 6 is the element by means of which the carriage device 5 is solidly connected to the glass panel 3.

[0032]The peculiarities of the carriage body 6 are described below.

[0033]According to the present invention, the carriage device 5 further comprises a wheel group 7, which comprises two wheels 71 suitable to slidingly engage the rail 21. [0034]Said wheel group 7 comprises a support frame 70 to which the wheels 71 are hinged to be rotationally free. [0035]Preferably, the wheels 71 comprise wheel pivots 715 by means of which they are rotationally fixed to the carriage body 6. [0036]In particular, according to the present invention, the carriage body 6 and the support frame 70 are mutually engaged by a hinge, which allows reciprocal rotation.

[0037]According to a preferred embodiment, the carriage body 6 comprises a housing seat 65 and the support structure 70 comprises a hinging pin 75 which is housable in said housing seat 65 rotationally free. According to a preferred embodiment, the hinging pin 75 extends transversally; similarly, according to a preferred embodiment, the housing seat 65 has a complementary shape.

[0038]According to a preferred embodiment, the two wheels 71 are axially aligned having respective rotation axes lying on the same imaginary plane.

[0039]Preferably, the wheels 71 are mounted so as to be aligned longitudinally.

[0040]Preferably, the wheel pivots 715 are mounted to be parallel to the transverse axis Y-Y.

[0041]According to a preferred embodiment, the hinging pin 75 is positioned longitudinally in a region between two wheels 71, preferably at the center line of the distance present between the two hinging points of two wheels on the support frame 70.

[0044]According to a preferred embodiment, with an odd number of wheels, the hinging pin 75 is positioned aligned with the central wheel.

[0045]In other words, the action due to the weight of the glass panel 3 is relieved onto the respective rail by means of the wheels 71 provided in the carriage device 5. [0046]According to a preferred embodiment, the carriage body 6 comprises an upper structure 61 solidly connected to the glass panel 3 and a lower structure 62 with which the wheel group 70 is engaged. [0047]According to a preferred embodiment, the upper structure 61 and the lower structure 62 are mutually positionable in a plurality of relative positions as a function of needs.

[0048]In particular, indeed, each relative position of the upper structure 61 with respect to the structure 62 corresponds to a respective distance between wheel group 7 and second edge 32 of the glass panel 3.

[0049]Preferably, therefore, the adjustment of the position of the two structures allows the height regulation of the glass panel 3.

[0050]According to a preferred embodiment, the upper structure 61 and the lower structure 62 respectively comprise an upper inclined plane 610 and a lower inclined plane 620 suitable to allow sliding operations on each other.

Preferably, the adjustment member 66 is operable to adjust the mutual position of the lower structure 62 with respect to the upper structure 61. In other words, the adjustment member 66 imposes a preferred position of the lower structure 62 with respect to the upper structure 61 (the latter fixed to the glass panel 3).

[0053]According to a preferred embodiment, the adjustment member 66 is a screw element 660 having a longitudinal extension such that its rotation implies a longitudinal and vertical adjustment of the lower structure 62 with respect to the upper structure 61.

[0054]An example of adjustment of the two structures is shown by way of example in figures 6a and 6b. [0055]According to a preferred embodiment, each rail 21 comprises a stem 211 and a head 212, having a substantially T-shaped cross-section.

[0056]According to a preferred embodiment, the wheels 71 slide on said head 212 comprising a central slot 712 in which said head 212 is seated. [0057]According to a preferred embodiment, the carriage body 6 further comprises an anti-lifting member 67 comprising two teeth 670 facing each other.

[0058]Preferably, the anti-lifting member 67 is suitable to avoid a relative lifting of the carriage device 5, and thus of the glass panel 3, with respect to the guide 2. [0059]According to a preferred embodiment, the head 212 is seated in the space between the two teeth 670, which comprise projections 670' that protrude transversely towards each other to avoid an axial movement. In other words, the anti-lifting member 67 contains the head 212 of the rail 21 therein.

[0060]Preferably, the anti-lifting member 67 is mounted on the lower structure 62. In other words, the anti-lifting member 67 is also subject to relative height adjustment with respect to the guide.

[0061]Preferably, the teeth 670 are made of soft material, e.g. plastic material, to allow inserting the carriage device 5 onto the respective rail 21 also in a vertical direction.

[0062]In addition, according to a preferred embodiment, in which the carriage body 6 further comprises a fixing member 69 suitable to engage a respective end jamb 40 to fix the respective panel 3 to the jamb.

[0064]Preferably, the fixing member 69 comprises a fixing tooth 690 and elastic fixing elements 695 suitable to push on the fixing tooth 690 to keep it in a fixing position.

[0065]Preferably, to release the glass panel 3 from the end jamb 40, it is necessary to perform an operation on the fixing member 69, which overcomes the pushing action produced by the elastic fixing element 695. [0066]Preferably, the fixing member 69 comprises a command lever 699 suitable to allow said operation.

[0067]Innovatively, the movable panel system has a particularly efficient and reliable translational movement of the respective panels. [0068]Advantageously, the carriage device is suitable to move glass panels of large dimensions, and, therefore, of heavy weight.

[0069]Advantageously, the carriage device allows an effective sliding on the respective guide. [0070]Advantageously, the carriage device has a wheel assembly which adapts to the shape and possible inclination of a respective rail.

[0071]Advantageously, the carriage body is adjustable simply and intuitively to adjust the height of the glass panels. [0072]Advantageously, the anti-lifting member ensures the vertical blocking of the carriage device to the respective rail. Advantageously, the anti-lifting member allows an engagement thereof with the rail in a vertical direction.

[0073]Advantageously, the fixing member allows a simple coupling action as well as a simple releasing action.
