Definitions

  • the invention relates to a folding partition structure consisting in a set of adjoining panels slidable in tracks, alternated with intermediate hinge post sections and joined together by hinges that are concealed from external view.
  • Numerous types of partition systems are currently marketed, which consist in folding panels designed to glide between top and bottom horizontal tracks. These folding panel systems are especially useful for partitioning off and protecting open spaces such as terrace roofs, balconies, porticoes, etc.. The panels can be stowed away one against the next in simple fashion to the end of minimizing the space taken up when not in use.
  • folding panel systems of the type in question can be used advantageously to partition off internal spaces in a wide variety of ways, each such partition being swiftly removable.
  • a first drawback stems from the fact that the structure of most partitions is somewhat complex and costly.
  • Another folding partition structure incorporates an intermediate hinge post section, located between and articulating with each two adjacent panels.
  • the upright stile sections of the panel sashes in this system are provided at each articulation with two contact surfaces contoured in the shape of an arc to a circle, each concentric with the point of articulation itself, and the intermediate section with two corresponding seals designed to engage the contact surfaces as the panels rotate. Whilst able to solve the problems of heat and sound insulation, this latter solution is still by no means free from drawbacks; in effect, such folding structures have proved slow to sell by reason of the high cost of manufacture involved in producing the particular contour of the sash stile section.
  • a second disadvantage stems from the fact that tight contact must be ensured between the contoured surfaces of the panel sash stile sections and the respective seals in order to obtain good acoustic insulation during rotation of the panel; thus there is strong sliding friction between the surfaces and the seals, resulting in heavy wear on the seals.
  • a further limitation affecting structures of this type is due to the fact that the extended partition can be made to follow a curved track on one side only.
  • the single panel can rotate in relation to the intermediate post section through no more than 90° from the fully open position to the folded and stowed position, so that no rotation whatever is possible in the direction opposite to the folding direction.
  • a first drawback stems from the fact that the pivot to which the locking ring is fitted must first be machined, and therefore requires prior adaptation to suit the type of hinge adopted.
  • a second drawback stems from the fact that, in the event of the sash and frame needing to be separated from one another, the locking ring must first be removed; not only is this an operation requiring special tools, but notable additional difficulties also arise, especially with hinges installed in positions that deny easy access.
  • the object of the present invention is to overcome the drawbacks mentioned above.
  • a further advantage consists in the fact that the structure according to the invention can be used easily for non-rectilinear partitioning, whereby the panels, which swing to either side of the hinge centre through a certain angle, can be positioned along any given curved trajectory.
  • the seals adopted are not affected by problems of wear.
  • the significant proximity of the sash stile sections and the intermediate post sections, attributable to the particular arrangement of the hinge, enables the use of ordinary abutting seals.
  • An additional advantage of the structure disclosed is that no relative axial movement of hinge parts can occur, and the risk of sashes being blown off by the wind is thus eliminated.
  • routine maintenance of the panels is much facilitated, even of the external faces that are often difficult if not altogether impossible to reach in conventional structures, as the sashes can be lifted easily from their pivots when folded into the stowed position.
  • the structure 1 consists substantially in panels 5 and intermediate sections 2 located between the panels 5.
  • the panels 5 consist preferably in centred panes of glass, and sash frame members 7 surrounding the panes.
  • Each intermediate section 2 connects on either hand with the adjacent panel 5 by way of a hinge 3 that is located between the longitudinal median plane 4 of the panel 5 and one or other of the two external faces 6 of the sash.
  • Each hinge 3 is accommodated within the dimensional compass of the corresponding panel sash member 7, in such a way as to remain concealed from external view and thus ensure that the appearance of the panels 5 will not be adversely affected when the partition is extended.
  • the positioning of the hinge 3 is advantageous in particular as it enables the upright sash members, i.e. the stile sections 7, to be brought markedly close to the corresponding intermediate sections 2, when the panels 5 are drawn out into the extended configuration of the partition.
  • the seals 8 can be of different types and differently disposed.
  • each seal 8 is fitted directly to the intermediate section 2, anchored in relative seatings 18 located at the vertical edges. Accordingly, when the panels 5 are folded away into the stowing position, each seal 8 will be located between the flank surface 17 of the intermediate section 2 and the adjacent external face 6 of the panel 5. Positioned thus between the two surfaces, the seal 8 functions as a soft cushioning medium.
  • each seal 8 is split into two matching parts 8a and 8b.
  • both the intermediate section 2 and the stile section 7 afford seatings 18, 14 to accommodate the respective parts 8a and 8b.
  • the seatings denoted 18 are located along the vertical edges of the intermediate section 2; the seatings denoted 14, on the other hand, are the same as in figs 1 and 2.
  • This particular arrangement of the seals 8a, 8b is especially advantageous in cases where magnetic types are adopted.
  • the magnetic force of attraction which persists when the lips of the seals 8a and 8b are offered to one another, is such as to ensure an efficient excluding action even with seals that have become especially worn or deformed.
  • the intermediate section connects with the hinge 3 by way of an element 9 which, being appropriately profiled, allows the adjacent stile section 7 to rotate freely, but in such a way that no contact is possible geometrically between the stile and the element 9 when the panel 5 is rotated.
  • the interconnecting element 9 issues from the flank 17 of the intermediate section 2 directed toward the hinge 3 and is L-shaped, thus creating a recess in which to accommodate the edge 13 of the stile section 7 when the relative panel 5 is folded into the stowed position.
  • the stile sections 7 are fashioned with a rounded profile at the edges 13, in such a way as to minimize the space necessary for rotation.
  • the hinge 3 is connected by way of a second element 10 with the stile section 7 of the panel.
  • the two interconnecting elements 9, 10 will engage with the intermediate section 2 and the stile section 7, respectively, by way of positive sliding fittings 11 and 12.
  • the elements 9 and 10 might equally well be associated removably with the sections by means of other fasteners such as screws, bolts etc.
  • the fitting denoted 12 consists in a slot 16 running longitudinally and in relief along the flank 17 of the intermediate section 2.
  • the side face of the slot 16 farthest from the hinge 3 is located advantageously behind and directly adjoining one of the seals 8; in this way, the face also provides a stop to check the inwardly-directed flexural movement of the seals 8, caused by wind or draught, while presenting an internal labyrinth profile to any air that may in fact infiltrate.
  • the check for the seals 8 can be fashioned as illustrated in fig 2, in the form of a simple fin 15.
  • a simple fin will be located, clearly enough, in the area opposite that occupied by the hinge 3 in relation to the longitudinal median plane 4 of the panel 5, and positioned longitudinally on the flank 17 of the intermediate section 2; needless to say, the fin 15 will extend continuously along the entire length of the seal 8 if its function as a stop is to be performed to best effect. Disposed thus, the fin 15 provides an effective labyrinth against any infiltration of air, water etc.
  • the folding partition disclosed possesses the capacity to bend marginally, even toward the side opposite that on which the panels are folded away for stowing. Accordingly, it becomes possible for the extended partition to follow trajectories deviating on either side from the median plane 4, with equal ease.
  • the hinge 3 used in the folding structure which consists essentially in a pivot and a bushing, also comprises an interference element denoted 20.
  • the interference element 20 is rigidly associated with one component of the hinge assembly (pivot or bushing) and stationed outside the dimensional compass normally allowing relative axial movement of the hinge components.
  • the interference element 20 is positioned so as to register with a given component of the partition structure and disallow its movement along the axis of rotation of the hinge 3.
  • the interference element 20 can be embodied, as in the example illustrated, in such a way as to enter into contact with the intermediate section 2 by way of the element 9 interconnecting the section with the respective component of the hinge 3.
  • the function of the interference element 20 is linked to two particular positions: a first of non-­interference, in which the intermediate section 2 is easily separated from the point of articulation, and a second of interference in which movement of the relative interconnecting element 9 in an axial direction is disallowed by reason of the fact that the interference element 20 is rigidly associated with the interconnecting element 10 of the sash stile section 7, hence with the remaining component of the hinge.
  • the dimensions and shape of the interference element 20 permit of selecting an angle of rotation of the panel 5 at which its movement in the axial direction will be either enabled or inhibited; moreover, the interference element 20 can be associated removably with the relative component of the hinge 3.
  • the folding structure is rendered significantly more stable and safe in the extended configuration, given that freedom of relative axial movement at the various points of articulation is entirely eliminated.
  • the intermediate sections 2 will become freely detachable from the sashes 5 at the respective hinge 3, automatically, when the panels are folded back.
