Description

HINGE FOR GRIDS, OPENABLE MESHES AND THE LIKE

  The present invention relates to hinges for doors, grilles, openable gratings and the like, and more particularly a hinge which allows an opening up to 180 of a frame also in the presence of side walls or side jambs or of another element in its

  range of rotation from the closed position.

  Windows, French windows, doors and the like are generally fitted with external frames such as shutters, louvers, gratings or open fencing, with one or two leaves, which make it possible to protect the premises of a building against atmospheric agents, regulate ambient lighting and increase safety

when they are closed.

  If these frames are mounted in the opening of a respective window or French window opening, their opening on usual hinges or hinges is limited by the sides or jambs of said opening and cannot reach 180 towards the outside until they approach, parallel to the wall,

  the edges of the window or French window.

  This is even less achieved in the case of opening protective grilles or gratings which are placed, as is often the case, between an interior glazed frame and an exterior frame in the form of shutters, shutters, blinds, or the like. In such a case, in fact, for an opening of 180 towards the outside and on the side, a grid or a mesh must be able to protrude beyond the outside frame to be superimposed on it when the two frames

  intermediate and external are both open.

  For such a spacing and to allow the rotation towards the outside of a protective frame beyond the sides and jambs of a window or French window frame, special hinges are already available, which however require manual intervention. to unlock a given state of rotation to move to a

  another which allows an opening of 180.

  The main object of the present invention is to provide an improved hinge without any locking / unlocking means and capable of allowing an opening of 180 of a protective frame of the type and under the abovementioned installation conditions without having to

  intervene manually on the hinges.

  Another object of the present invention is to provide a hinge for grids, openable gratings and the like, of simple and economical construction and having a

  good reliability and functionality.

  Said objects are achieved, according to the invention by a hinge which comprises a fixed support to be subjected to a pedestal or jamb of a doorway, window or French window or the like, an articulation plate associated with said support, extending from it and rotating about a first vertical axis, carried by the fixed support, a pivot element, part of a leaf of a protective frame structure, associated with said plate hinge and rotating about a second vertical axis, carried by said plate, and a slide plate placed and movable longitudinally between said support and said pivot element so as to allow rotation of the frame leaf around the second vertical axis to a first determined opening angle from the closed position, then a rotation of the frame leaf in a united manner with the hinge plate around the

  first vertical axis for a later opening angle.

  The present invention will be described in more detail.

  in the following description with reference to the drawings

  joints, given by way of non-limiting indication, and on which: FIG. 1 illustrates the perspective view of a hinge when it is applied to a pedestal or jamb of a doorway of a French window, for example; Figure 2 illustrates an example of a

  double-leaf opening protection applied to a door

  window, provided with hinges according to the invention; Figure 3 illustrates a schematic transverse view of the closed frame at the hinges; Figure 4 illustrates a view similar to that of Figure 3 but which shows the partially open frame; Figure 5 illustrates a view similar to that of Figure 4 but which shows the fully open frame; FIG. 6 illustrates, in perspective, the hinge according to a second embodiment of the invention; and Figure 7 illustrates the hinge shown in the

Figure 6 in longitudinal section.

  The hinge illustrated in Figures 1 to 5 comprises a fixed support 11, a hinge plate 12, a slide plate 13 in combination with a hinge element 14 which is part of, or is fixed to, a frame structure of protection, in the form of a door, a grid, an openable mesh or the like, with two leaves 15, as shown in the drawings, or

well to a single leaf.

  The fixed support It must be secured, using any suitable fixing means, to a pedestal or jamb 16 of a door, window or French window frame where the frame structure 15 must be applied. The support 11 has a horizontal part 11 'and a vertical part 11 ", thus forming a square. The articulation plate 12 is associated with the horizontal part 11' of the fixed support 11. More precisely, the articulation plate 12 has a proximal end which is bolted, with a first pivot with vertical axis 17, to the horizontal part of the fixed support 11 and can rotate around said pivot. The articulation plate also has a proximal end configured in the shape of a cam 12 ′ and intended to interact with the vertical part 11 "of the fixed support. The proximal cam 12 'is presented with a straight part and a part

blunt or rounded.

  The pivot element 14, which is part of the frame structure 15, is bolted, with a second pivot with vertical axis 18, to the distal end of the articulation plate 12 and rotates around said pivot, allowing rotation opening and closing

wing of respective frame.

  It should be noted that the first pivot 17 and the second pivot 18 may be constituted by corresponding parts of vertical rods 15 'contributing to the

  frame structure formation 15.

  The slide plate 13 is in a superimposed relationship with the connection plate 12 and is arranged between the horizontal part 11 'of the support 11 and the free end of the hinge element 14. The slide plate 13 is secured to the hinge plate 12 by means of guide pins 19 but is also capable of effecting longitudinal movements thanks to the presence of slotted orifices 20 in correspondence with the guide pins. The slide plate can also be traversed vertically, in correspondence with another slotted orifice 21, from another of the rods 15 'of

the frame structure.

  The free end of the hinge member 14 is configured as a cam 14 ', in the same way as the proximal end of the hinge plate, and interacts with the adjoining end of the hinge plate.

slide 13.

  Of course, any frame leaf 15 will have at least two hinges according to the present invention, spaced apart in height and the hinges will be provided for an opening to

  right or left of the leaves.

  When all the leaves 15 are in the closed position (Figures 1 and 3), the fixed support 11, the hinge plate 12, the slide plate 13 and the hinge element 14, forming part of the leaf, are aligned. , and the articulation plate is in support, on one side, with the rectilinear part of its proximal cam 12 'with the vertical abutment part 11 "of the support 11 and, on the opposite side, with the end cam 14' of said element

forming a hinge 14.

  Starting from such a position, each frame leaf 15 can be opened initially by being turned, substantially on 90, around the second rotation pivot 18 as shown in Figure 4, then, by rotation, substantially 90 more , around the first pivot 17 of the hinge as shown in Figure 5. In the closed position and up to the open position with a first rotation of 90 of the leaf, the slide plate 13 maintains in rigid alignment the plate d hinge 12 and the support there insofar as it is pushed by the hinge element 14 against the free end of said support, thus making it impossible

  the rotation of the hinge plate 12.

  When the leaf has been turned 90 around the second pivot 18, the slide plate 13 is free to slide longitudinally, being able to move away from the fixed support and allowing the rotation of the articulation plate around the first pivot 17, without any

  manual intervention on the hinges.

  To close each leaf, the opposite occurs: first, the system is rotated in the opposite direction around the first pivot 17, until the rigid coupling of the hinge plate 12 with the support 11 through the slide plate 13, then the leaf is rotated around the second pivot 18

until closing.

  Of course, with an appropriate choice of the center distance of the pivot pivots 17, 18, it will be possible to obtain an outward displacement of the open leaf in a manner compatible with the width of the pedestals or legs of the doorway to which the built and in

  function of a possible other more external structure.

  In an alternative embodiment illustrated in FIGS. 6 and 7, the hinge also comprises a fixed support 31 to be fixed to a pedestal or jamb 16 of a door, a window or a French window, and a hinge member 32 which is part of, or is attached to, a protective frame structure, in the form of a door, a grid, an openable mesh or the like, with two leaves 15; instead of the hinge plate 12 and the slide plate 13, this hinge however has a single intermediate plate 33 having a proximal end 34 which is bolted, with the first pivot with vertical axis 17, to the horizontal part of the fixed support 31, and a distal end 34, to which is bolted, with the second pivot pin

  vertical 18, the hinge element 32.

  For rotation in one direction around the pivot 17, the proximal end 34 of the intermediate plate 33 is configured in the shape of a cam, or has a straight part and a blunt or rounded part, and is intended to interact with a stop 31 '

on the fixed support.

  Similarly, for rotation in one direction around the pivot 18, the free end of the hinge element 32 is configured as a cam 32 'and interacts with a stop 34 "on the plate.

intermediate 33.

  As shown in Figures 6 and 7, so that this variant of the hinge has the same thickness over its entire length, the intermediate plate 33 is T-shaped, while the fixed support 31 and the hinge element 32 have zones lowered 31 "to 32" on which the corresponding ends 34 rest and

34 'of the intermediate plate 33.

  Then, the distal end 34 'of the intermediate plate 33 is also configured in the shape of a cam to allow the rotation of the hinge element 32 around the rod 18, just like the lowered area 31 "of the fixed support 31 is configured as a cam to allow the rotation of the intermediate plate 33 around the pivot 17. This variant embodiment of the hinge allows, unlike the first embodiment, to rotate the intermediate plate 33 around the first pivot 17 even when said plate 33 is aligned with the forming element

hinge 32.

  Finally, it should be noted that the hinge develops according to the functional succession of plates 32 and 33 until it reaches the desired length of the frame or the mesh to be rotated. In correspondence with the other upright 35 of the frame, there may be provided another element in the form of a plate or fixed support 36 with which a device such as, for example, a lock (not shown) for blocking the latter may be associated.

  plate 33 and, therefore, of the entire hinge.

  Of course, the present invention is not limited to the exemplary embodiments described above and shown from which other modes and other embodiments can be provided while remaining within the scope of the invention such that defined by

appended claims.
