Definitions

• a gate with an extendable and retractable articulated structure is provided.
• 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.
• the invention resolves the said technical problem by adopting, between the two abutments attached to corresponding supports, a sliding articulated structure, consisting of two layers of inclined thick gauge linkages, extending the entire height of the gate, inclined in two near-vertical directions, hinged to each other and to two supporting uprights by means of structural elements: one of the two uprights being mobile and securely closed with the abutment containing the lock (or other anchoring mechanism) , the other being inserted in and attached to the opposing abutment; the base of the mobile upright having a wheel with the function of facilitating movement across the sill, or threshold, especially for long gates to avoid overstressing the structure: the self-supporting condition being made possible by the use of hinging and distancing elements between the linkages and between the linkages and their supporting uprights.
• the advantages offered by the invention are: elimination of the vertical risers, of the suspension and sliding runner for the upper extremities of the risers and the runner for the lower extremities; elimination of the drilling of the lintels, the sills and the thresholds; elimination of the dust and dirt traps; increase in the effective dimensions of the openings; greater speed of installation and removal; reduced difficulty of operation due to improved smoothness; elimination of obstacles in hanging up drapery at windows; possibility of installing the gate in openings of walls or fencing.
• 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
• Figure 10 is the front view of the support element that carries the lock;
• Figures 12, 13 are, respectively, the interrupted front view and corresponding plan view of one of the two abutments (left);
• Figures 14, 15 are analogous frontal and plan views of one of the two uprights (left);
• Figures 17, are analogous frontal and plan views of the other upright (right);
• Figures 18, 19 are analogous frontal and plan views of the abutment with the lock.
• 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 to 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 sill 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.
