Definitions

  • the present invention relates to a device for stabilising the closure of folding door wings.
  • Another problem is that of keeping the wings, when the door is closed, in a position which is stable enough yet not too rigid, since, when the door is opened, the wings must swivel on their joints requiring a moderate effort to be opened.
  • the prior art has devised accessories for the reversible locking of the wings in a coplanar position, located over the metal rods of the hinges. These accessories comprise a flexible foil, fastened on top of one of the metal rods, whose head is shaped like an inverted V and which is meant to be coupled with a corresponding protruberance obtained on the other metal rod on the other wing.
  • these elastic accessories may be subject to frequent failures, in particular in the area where they are fastened to the metal rods, and their replacement is not immediate.
  • the purpose of the present invention is to eliminate the drawbacks mentioned above.
  • the invention as characterised in the claims, solves the problem of conceiving a device whose metal parts, elastically movable axially, are so designed as to create a torque, on the articulated joint of the wings, such as to keep the wings stably closed until a force is imparted manually to open them.
  • the present invention attains its stabilised wing closure configuration smoothly and progressively, without sudden metal clicks, while the opening action of the wings is initially made easier and cushioned throughout their travel.
  • the device in general, comprises a mechanical component (3), that can be elastically deformed along its axis which passes at such a distance, from the axis of rotation (r) of the joint (4) coupling the wings (1, 2), as to originate, by restraining elastic reaction against a stop (5), a torque (M), around the axis of rotation (r), sufficient to maintain the two wings (1, 2) perfectly coplanar in the closed position, when no opening force is imparted.
  • a mechanical component (3) that can be elastically deformed along its axis which passes at such a distance, from the axis of rotation (r) of the joint (4) coupling the wings (1, 2), as to originate, by restraining elastic reaction against a stop (5), a torque (M), around the axis of rotation (r), sufficient to maintain the two wings (1, 2) perfectly coplanar in the closed position, when no opening force is imparted.
  • the mechanical component (3) comprises a first guiding element (31) and a second element (32) associated to the first and guided by it, in order to be able to move from a first extreme position with nil restraining force, with the wings folded and parallel, to a second extreme position of maximum restraining force, with the wings coplanar.
  • the second element (32) acts on the stop (5), in correspondence with the upright (7) of the jamb of the folding door (8).
  • Between the first and second element (31, 32) are interposed elastic means (33) able to originate the aforesaid elastic reaction.
  • the mechanical component (3) could thus simply comprise an elastic component inserted crosswise in the upright (7) of the jamb with the stop (5), opposite to it, placed in the upright of the wing (1) or vice versa, in such a way as to allow a forced contact between the elastic component and the stop (5), with no need, theoretically, to fit sliding guides for the opening or closing of the wings.
  • the mechanical component (3) is fitted along the horizontal peripheral edge (66) of one of the crosspieces (6) of the closing wing (1), the articulated joint (4) between the two wings being cantilevered in the opposite direction to their folding angle (see Figures 1, 2 and 3).
  • the first element (31) of the mechanical component (3) is in this case a shaped rectilinear rod (34), attached along the edge (66), while the second element (32) is a slider (35) whose shape complements that of the rod (34) and whose length is at least such as to include both the length of the rod (34), and of the elastic means (33) in their fully extended configuration, as is clearly shown in Figures 1, 4 and 5.
  • the elastic means (33) are interposed between the end of the slider (35) facing the joint (4) coupling the wings (1, 2) and the corresponding end of the rod (34).
  • the second and opposite end of the slider (35) instead acts directly on the stop (5) in correspondence with the jamb, in the configuration with the wings coplanar, so that said maximum restraining reaction occurs with the elastic means (33) fully extended, as clearly shown in Figure 1.
  • the stop (5) coincides with the upright (7) of the jamb of the folding door (8), whereas in the embodiment shown in Figure 4 the stop (5) is a fixed limit stop (10) of the fixed groove (11) guiding the pin (9).
  • the elastic means (33) unload, returning to the rest position ( Figure 2), while the pin (9) (or the second end of the slider), essentially remains in its limit position, set against the stop (5).
  • the opening of the wing (1) is initially aided by the action of the elastic means as they unload. Subsequently, the opening of the wings is cushioned by the very presence of the elastic means ( Figure 3).
  • the rod (34) and the slider (35) are fitted along the horizontal peripheral edge (66) of the top crosspiece (6) of the folding wing.
  • the rod and the slider are flat elements and their maximum thickness, as well as that of the elastic means (33) is smaller than the vertical dimension of the rabbet edge (12) of the folding wing (1).
  • the rod (34) has a lateral shape (15) complementing that of a corresponding shape (16) within the slider (35), the latter being fitted with a centre slot (17), destined both to make room for the rod (34), introduced in it so that its thickness is included in that of the slider (35) and to contain the elastic means (35), also included in the same thickness ( Figure 4).
  • the joint (4) in the configuration with the wings coplanar, also fits within a concealing housing (13), obtained on the crosspiece (14) of the jamb of the folding door (8).
