Definitions

  • the invention concerns a gate with an extendable and retractable articulated structure, that is, a vertical lattice able to slide transversely to close-off openings in windows, doors, walls, or fencing in general, for safety purposes.
  • the prior art involves single-piece extendable and retractable lattices for windows or french windows, made up of structures having an abutment, attached to the wall section, with a locking mechanism in which to secure a latch carried by a corresponding vertical sliding upright which is connected on its other side, by means of one or more sets of series of thin, short articulated linkages, cross-linked in a parallelogram configuration, to a sliding vertical upright having drilled flanges to attach it to the opposing wall section or fixed abutment: between the said sliding upright and this last fixed abutment, there being a number of evenly spaced vertical risers, each made up of two opposing C-sections, inside each of which there being, at the same height in each set of said crossed linkages, the pins that constitute the median node of each formation of linkages, whereas the pins that constitute the upper and lower hinges with respect to the median node can slide vertically inside the said vertical risers and inside the vertical upright that does not have the lock; the upper extremities of the said vertical sliding
  • This type of extendable and retractable gate has the considerable drawback of requiring the lintels, sills and thresholds to be drilled in order to insert the screws or expansion plugs to attach the said runners, spoiling or damaging the respective surfaces, especially if they are made of marble, in such a way that they cannot be restored should this be required.
  • the lower runner in particular constitutes an obstruction and a receptacle for dust and dirt.
  • the runners are also a source of difficulty in manoeuvering and installation as well as in using the gate, they reduce the effective height of the window or door and constitute an obstruction when hanging curtains, sheets or drapes at the window as required.
  • FR-A-8907886 which is considered to represent the closest prior art, discloses an automatic door having an extendable structure comprising a plurality of opposingly inclined bars pivotally joined at their points of intersection and having outer ends vertically slidably mounted on a fixed upright and on a movable upright by means of respective transverse hinge pins slidably coupled in vertically extending slots in the upper portion of the uprights.
  • the positioning of the hinge pins into the slots to determine positioning of the door with respect to the opening is quite precarious, since it depends on the radial play between each pin and the respective slot, the play being variable over the working of the door and becoming larger after a certain period of countinuos functioning. A certain play is requested also because the door is designed to reach the closed position under the action of the weight of the bars.
  • GB-A-2183716 and GB-A-2224073 disclose similar gates, but in which the bars are provided, in their outermost portions, with rollers slidably movable along a lower support track, an upper riser support track, a fixed support track and a movable side support track.
  • the rollers are free to rotate around respective pins and, when the user decide to open or close the gate, said rollers necessarily roll along the tracks without opposing any substantial reaction to the movement of the gate.
  • a further disadvantage of this gate is that a plurality of tracs is provided for guiding said rollers, which renders the installation quite complicated.
  • AU-B-596065 also discloses an extendable and retractable gate, having a lattice-like structure defined by obliquely disposed bars cross-linked in a planar arrangement and connected to vertical supports by means of sleeves.
  • the sleeves encicle the outer surface of the supports so that are dangerously accessible from outside and therefore do not guarantee sufficent protection.
  • a coil tension spring system bias the gate in its closed position.
  • the technical problem solved by the present inventon is therefore of inventing an extendable and retractable gate having an articulated structure which is safe, does not require horizontally extending vertical supports, i. e. upper and lower support tracks, and allows correct and precise positioning of the gate both in opening and in closing operation.
  • a gate comprising an extendable and retractable articulated structure for barring openings, comprising two layers of inclined members and at least one supporting upright, each layer of members being inclined in opposing inclined directions, said members being connected to each other at their points of intersection by first connecting means and to the at least one supporting upright at a respective lateral end of the structure by second connecting means, said structure being attached to a fixed section of the opening having at least one abutment provided with first anchoring means, the inclined members being connected to each other and to the at least one supporting upright in such a way as to provide a self-bearing structure without the need for further vertical supporting elements, said members being connected with sliding means slidably movable in a track means, said track means being only provided into said at least one supporting upright, characterised in that said sliding means comprises sliding blocks slidably engaged with the inner surface of the respective supporting upright; spacing means being interposed between said sliding blocks.
  • Figure 1 is a partial front view from the inside of the gate with the corresponding uprights in the closed position, shown, purely for the purposes of greater clarity, separated from the abutments and with only one of the far-side linkages, of which there are, in fact, as many as on the near-side, drawn with dashed lines, the front-side linkages being only shown in part: each linkage constituting a hinging support for the other linkages so creating the vertical articulated self-supporting structure of the gate;
  • Figure 2 is the enlarged longitudinal centre-line section of one of the far-side linkages as drawn with dashed lines in Figure 1, showing the sections of the near-side linkages hinged at various heights to form the vertical structure;
  • Figure 3 is an interrupted front view from the inside the gate as applied, for example, in the opening of a window;
  • Figure 4 is an interrupted plan view, enlarged and partially sectioned, of the two extremities of the gate in its fully extended position, showing the
  • the figures show: 1, the near-side linkages (i.e. internal) inclined from the vertical to one side; 2, the far-side linkages (i.e. external) inclined in the opposite way; 3, through holes in linkages 2 for the insertion, in each of the holes, of hollow spindle 4 (Figure 2) having on one side head or boss 5, on the other side screw thread 6 into which is screwed screw 7 with washer 7a, in such a way so that it cannot be removed: the hollow spindle extending into the corresponding hole in the other inclined linkage; 8, the C-section upright with lip 8a ( Figure 4) located on the opposite side of upright 9, also with lip 9a in its C-section, having slot 10 for lock 11, fixed to abutment 12, also with C-section: upright 9 being mobile, whilst upright 8 is fixed; 13 ( Figure 3), a handle for operating the gate; 14, the opposite abutment, with C-section, from the one with the lock; 15, holes in the sides of abutment 14, to attach upright 8 inside it by drilling during assembly and inserting
  • Assembly is as follows: once abutments 12, 14 have been attached to the walls, or th the fixed part of the structure with the opening, using expansion plugs and screws 19, upright 8 is inserted in corresponding abutment 14, fixing it in place with transverse screws 16 placed in holes 15, after the corresponding holes have been drilled with the upright in position; wheel 18 will roll across the soll or threshold, as abutment 14 and its corresponding fixed upright 8 are made shorter so as to keep them lifted by an amount approximately corresponding to the amount that the wheel protrudes from the lower extremity of mobile upright 9, also made correspondingly shorter.
  • the abutment (14) opposite the one with the lock could be eliminated, advantageously or not, attaching the corresponding upright (8), by means of side plates and screws, directly to the wall section.
