Description


[0001] The object of the present invention is a packable movable panel system, in particular glass panels.

[0002] In the state of the art are known packable movable panel systems that allow one to enclose an environment, such as a veranda, when weather conditions are unpleasant, in this way enabling its use as an additional sheltered space. When, however, the weather permits, the panels can be packed into a small space and the veranda can thus be used as an open environment.

[0003] In the known embodiments, the panels, preferably glass, are large, so as to allow an effective illumination of the environment even with the panels in the closed position.

[0004] Large glass panels are not easy to handle. In fact, to move the panels, special guides and special sliding means suitable to operate with such guides are provided to allow both the axial translation and movement in rotation.

[0005] In particular, embodiments are known in which the panel, in a rotated position, is placed cantilevered with respect to the guides. In fact, the panel is supported only on one side, while the other is rotated outside of the guide.

[0006] A critical problem with these typical solutions of the prior art, therefore, lies in the fact that the panels, in the open position, due to their dimensions and their weight, tend to tilt, assuming an undesirable and unappealing appearance.

[0007] Many packable movable panel solutions exist that have tried to solve this problem; for example, some of these solutions for movable panel systems are shown in the document number BS2009A000229 and in the document number WO2013/121330 in the name of the Applicant.

[0008] The object of the present invention is to provide a system of packable movable panels which ensures an efficient movement of the panels both in their axial translation, along the guides, and in their rotational movement, wherein the panels are cantilevered with respect to the guides.

[0009] This object is achieved by a packable movable panel system according to claim 1 below.

[0010] The features and advantages of the panel system according to the present invention will be apparent from the description given below, provided by way of nonlimiting example, in accordance with the accompanying figures, wherein:

[0011] In the accompanying figures, reference number 1 indicates a packable movable panel system object of the present invention, according to a preferred embodiment.

[0012] In particular, the movable panel system 1, object of the present invention, is not limited to, or by, the number of panels 3 included therein.

[0013] The movable panel system 1 comprises an upper guide 2 and a lower guide.

[0014] The upper guide 2 extends along an axis X-X. Preferably, the panels 3 are axially translatable along said axis X-X extending vertically relative thereto with respect to a vertical axis Z-Z.

[0015] The upper guide 2, furthermore, has internally a channel 20 provided with a lower opening 21. In other words, the upper guide 2 has substantially a C or U shape, with the opening facing downwards.

[0016] The panel system 1 comprises at least one panel 3 operatively connected to the upper guide 2.

[0017] Preferably, the panel 3 is operatively connected to the upper guide 2 to slide along the axis X-X and, once arrived in a predefined rotational position, to rotate with respect thereto around a vertical axis Z-Z.

[0018] Preferably, the panel system 1 comprises a plurality of panels 3, which in a closed configuration are arranged in a closed position, i.e. substantially coplanar to each other; in such a configuration, the system closes, at least partially, an opening of an environment, such as a veranda or a balcony (as shown by way of example in figure 1a). Preferably, on the other hand, in an open configuration, as described below, the panels 3 are rotated and packed parallel to each other at one end of the system 1 (as shown by way of example in figure 1e). In other words, for each panel 3 there is a predefined rotational position in which it is rotatable relative to the vertical axis Z-Z.

[0019] Preferably, the panel system 1 includes sliding, support and gripping means 5 suitable to allow sliding and support of a panel 3 in the upper guide 2.

[0020] In a preferred embodiment, such sliding, support and gripping means 5 comprise a pair of trolleys 50 housable in the housing channel 20 fixed to the panel 3 through the lower opening 21.

[0021] Preferably, the trolleys composing the pair 50 are mutually spaced, for example positioned respectively near the two lateral ends of the top of a panel 3.

[0022] Preferably, the pair of trolleys 50 comprises a first trolley device 51 and a second trolley device 52.

[0023] Preferably, the first trolley device 51 supports the panel 3 in sliding and in rotation and comprises a first bearing body 510 housed in the upper guide 2 and a rotation element 515 fixed to the panel 3 rotationally movable with respect to the first bearing body 510.

[0024] According to a preferred embodiment, the trolley device 51 comprises a plurality of pairs of support and sliding wheels 580 comprising at least one first pair of vertical wheels 581, each wheel having a rotation axis Y'-Y' perpendicular to the axis X-X and to the vertical axis Z-Z.

[0026] Preferably, the trolley device 51 comprises two pairs of vertical wheels 581, arranged on opposite sides of the first bearing body 510.

[0027] Preferably, the trolley device 51 comprises two pairs of horizontal wheels 582, arranged on the opposite sides of the first bearing body 510.

[0028] In accordance with a preferred embodiment, the above-described pairs of support and sliding wheels 580 are rotationally connected to the first bearing body 510.

[0029] Preferably, the first bearing body 510 has wheel housings 518 wherein the respective horizontal wheels 582 are housed.

[0030] In particular, each horizontal wheel 582 is housed in the respective housing 518 so as to protrude from the bearing portion 510 and thus contact the upper guide rail 2.

[0031] Preferably, in the embodiment comprising two pairs of horizontal wheels 582, the same are located at the four corners of the first bearing body 510.

[0032] According to a preferred embodiment, the pair of horizontal wheels 582 is positioned on the top of the bearing portion 510 at a height higher than the pair of vertical wheels 581.

[0033] According to a preferred embodiment, the second trolley device 52 supports the panel 3 in sliding.

[0034] Preferably, the second trolley device 52 comprises a plurality of pairs of support and sliding wheels 590 composed of at least one second pair of vertical wheels 591, each wheel having a rotation axis Y"-Y" perpendicular to the axis X-X and the vertical axis Z-Z. Preferably, the two wheels comprising a pair are arranged on the opposite sides of the second trolley device 52, for example diametrically opposed to each other.

[0035] The sliding, support and gripping means 50 comprise, furthermore, a gripping group 55 housed in the channel 20 operatively connected to the first trolley device 51 suitable to operate during rotation of the panel 3. In other words, the movable panel system 1 during the rotary operation of a panel 3 has a gripping group 55 acting to support the panel 3 and distributing the action of the weight force of said panel 3 directly on the upper guide 2.

[0036] Specifically, the gripping group 55 comprises a receiving device 551 positioned in an axial position corresponding to the predefined rotational position of the panel 3.

[0037] Preferably, the receiving device 551 comprises at least one rail 552 delimited by rail walls 552'.

[0038] Preferably, the receiving device 551 is positioned on an upper wall 22 of the channel 20, opposite the opening 21.

[0039] Further, in accordance with a preferred embodiment, the gripping group 55 comprises an engagement device 555 comprising at least one wedge element 556 which, in a rotated configuration of the panel 3 is inserted in the rail 552 by engaging the rail walls 552'.

[0040] In particular, the engagement group 555 is operatively connected to the rotation element 515 in such a way as to rotate therewith.

[0041] Preferably, the rotation element 515 extends in height along a rotation axis R-R corresponding to the vertical axis Z-Z with the panel 3 in the predefined position of rotation.

[0042] In a preferred embodiment, the rotation element 515 extends through a through cavity 511 of the specially shaped first bearing body 510.

[0043] According to a preferred embodiment, the wedge element 556 is arranged radially distant from the rotation axis R-R and extends along an arc of circumference.

[0044] Likewise, also the rail 552 extends along a specially shaped arc of circumference to receive the wedge element 556.

[0045] Preferably, the engagement device 555 comprises two wedge elements 556 arranged distally from one another, preferably arranged diametrically with respect to the rotation axis R-R.

[0046] In a preferred embodiment, the receiving device 551 comprises two rails 552 longitudinally spaced in such a way as to allow the wedge element 556 or the wedge elements 556 to translate axially between them. Preferably, in the embodiment comprising two wedge elements 556, these two wedge elements 556 respectively slide into the two rails 552, engaging the respective rail walls 552'.

[0047] In a preferred embodiment, the distance between the two rails 552 is substantially equal to the axial length of a wedge element 556.

[0048] In a preferred embodiment, each rail 552 extends for an arc of circumference such as to permit the rotation of the panel 3 by at least 90°.

[0049] In other words, the receiving device 551 and the engagement device 555 are suitable to slide one into the other during the rotation of the panel 3. In particular, these devices are suitable to be engaged as soon as the panel 3 is rotated.

[0050] In other words, the wedge element 556 has its own sectional shape complementary to the shape of the rail 552, possibly leaving a minimum space, for example through dimensional tolerances, to allow the mutual sliding between components.

[0051] In other words, the receiving device 551 and the engagement device 555 face each other.

[0052] According to a preferred embodiment, the receiving device 551 is, in its entirety or at least in the portion that delimits a rail 552, made of a material having a low friction coefficient, for example a material selected from the group of polyamides, synthetic and preferably nylon.

[0053] According to a preferred embodiment, the upper guide 2 comprises a first sliding track 211 and a second sliding track 212 on the sides of the lower opening 21 on which the first pair of vertical wheels 581 and the second pair of vertical wheels 591 slide in axial movement respectively.

[0054] In addition, preferably, the upper guide 2 defines a packing end 25 wherein the panel 3 is positionable and is rotatable with respect to the upper guide 2.

[0055] Preferably, in the packing end 25, the upper guide 2 has a lateral mouth 250 traversable by the second trolley device 52 in the rotational operations of the panel 3.

[0056] In accordance with a preferred embodiment, the lateral mouth 250 comprises two inclined portions 251 engageable by the second pair of vertical wheels 581 in the operations of traversing the lateral mouth 250.

[0057] According to a preferred embodiment, the upper guide 2 inside the housing channel 20 comprises a support tooth 28 extending along the axis X-X and projecting perpendicularly towards the center of the channel 20.

[0058] Preferably, the upper guide 2 comprises two support teeth 28 opposite to each other.

[0059] According to such an embodiment, the horizontal wheels 582 have a concave shape suitable to house such a support tooth 28 that runs along the same.

[0060] According to a preferred embodiment, the second panel device 52 has a second bearing body 502 to which the second vertical wheels 591 are operatively connected.

[0061] Also, the second panel device 52 comprises a fixing element 57 fixed to the panel and operatively connected in a rotationally movable manner to the second bearing body 502 around a recovery axis S-S. In other words, the second bearing body 502 is rotatable around said fixing element 57 facilitating, for example, the rotary operation of the panel 3.

[0062] Preferably, the second panel device 52 comprises elastic recovery means 570 suitable to allow the rotation around the recovery axis S-S of the second bearing body 502 and then return it to an aligned sliding position. In other words, the rotary movement between the second bearing body 502 and the fixing element 57, and thus of the panel 3, is guided by the elastic recovery means 570, for example by limiting the degrees of rotation between the components.

[0063] Preferably, the elastic recovery means 570 comprise a pin element 571 yieldingly fixed by means of an elastic element 572 to the fixing element 57, for example transversely to the recovery axis S-S.

[0064] In addition, the elastic recovery means 570 comprise a cam element 573 positioned on the second bearing body 502 and engaging the pin element 571 to exert a position recovery action thereon.

[0065] In other words, the pin element 571 is connected to the fixing element 57 positioned transversely thereto such that the latter is guided in rotation. In rotation, the pin element 571 operates with the cam element 573 and the elastic element 572 so that the latter is elastically loaded in such a way as to bring the pin back to its base axial position prior to rotation.

[0066] Innovatively, the packable movable panel system has a particularly efficient rotational and translational movement of the panel.

[0067] Advantageously, by virtue of the two trolley devices, the panel is able to slide in planar translation and move the said panels in rotation.

[0068] Furthermore, advantageously, the first trolley device and the second panel device are of compact size including a minimum number of wheels. Advantageously, the upper guide is small in size.

[0069] According to a further advantageous aspect, the sliding, support and gripping means comprise a gripping group suitable to ensure the engagement between the panel and the upper guide with the rotated panel. Advantageously, the mutual engagement between the receiving device and the engagement device, assured at every angle of the panel's rotation, allows the action of the weight force of the panel, rotated and cantilevered with respect to the upper guide, to be distributed. In other words, at any angle of rotation of the panel, the panel is prevented from tilting via the gripping means.

[0070] Also, advantageously, the first trolley device is equipped with horizontal wheels suitable to distribute the action of the weight force of the rotated panel on the upper guide.

[0071] Another advantageous aspect lies in the fact that the gripping means remain in engagement with the rotated panel and only cease to act when the panel is returned to a sliding position relative to the guide so as not to interfere with the sliding operations.

[0072] Advantageously, the receiving device is suitable to work in a balanced manner with respect to the rotation axis, for example by providing a pair of wedge elements respectively suitable to operate with a pair of specially shaped and arranged rails. Advantageously, two wedges are in contact with two rails in such a way as to distribute the action undergone between the two, becoming effectively usable with panels of large dimensions and high weight, such as glass panels.

[0073] Another advantageous aspect lies in the fact that the gripping group is small in size, being advantageously suitable to be housed in the upper guide. Advantageously, a substantially unlimited number of gripping groups are housable in the upper guide, i.e. equal to the number of panels, without any limit whatsoever.

[0074] Advantageously, the packable panel system has clean aesthetics, not interrupted by the presence of the gripping group, which is hidden from sight, as it is housed in the upper guide.

[0075] Also, advantageously, the gripping group is suitable to allow a movement in rotation of the panel with respect to the guides on both sides, being substantially symmetrical to the vertical axis. In other words, the packable panel system object of the present invention is thus ambidextrous.

[0076] Advantageously, the second panel device is suitable to recover the position of the second bearing body in such a way as to always keep the wheels thereon aligned in the housing to slide within the upper guide.

[0077] It is clear that one skilled in the art, in order to meet specific needs, may make changes to the movable panel system described above, all contained within the scope of protection defined by the following claims.

[0078] To the embodiments of said system, one skilled in the art, in order to meet specific needs, may make variants or substitutions of elements with others functionally equivalent. Moreover, each of the variants described as belonging to a possible embodiment may be realized independently of the other variants.
