Definitions

  • the present invention relates to a high security shutter with adjustable blades.
  • each adjustable blade comprises an aluminum profile supporting a pane and carried by hubs introduced by pressing its ends and in their turn carried turnably by holes of the uprights of the shutter frame.
  • Levers operatively connected to the shutter handle are fastened onto an end of said hubs by means of screws.
  • Frame uprights and crosspieces are fastened as a rule by means of screws, which during the transport thereof to the building yard and/or during the laying thereof do not ensure the necessary stiffness, so that the frame tends to deform and loses its squaring when resting on imperfect planes, due to its own weight or to anomalous stresses.
  • blades in closing position do not sometimes allow a sufficient contact pressure so as to ensure shutter watertight sealing.
  • required shutter height is not always a multiple of the height of said adjustable blades, which to manufacturers' convenience are carried out with a standard distance, so that an adjustable padding blade with suitable size is inserted into the air gap between the upper crosspiece of the frame and the last standard adjustable blade, which however makes shutter appearance worse.
  • the technical task of the present invention is therefore to make a high security shutter with adjustable blades that enables to overcome the technical drawbacks of known technique.
  • an aim of the invention is to make a high security shutter with adjustable blades offering an improved resistance to burglary and/or breaking and/or cutting.
  • Another aim of the invention is to make a high security shutter with adjustable blades that is solid, strong and mechanically stable, so as to keep squaring in case of normal or anomalous stresses.
  • Still another aim of the present invention is to make a high security shutter with adjustable blades and with extremely solid frame uprights, which do not deform even when being fastened onto a wall.
  • a further aim of the present invention is to provide a high security shutter with adjustable blades that enables to adjust contact pressure between blades, so as to obtain a perfectly watertight shutter in any situation.
  • an aim of the present invention is to make a high security shutter with adjustable blades that has a pleasant appearance even when a residual air gap of said shutter has to be covered with a blade having non standard size.
  • a high security shutter with adjustable blades comprising at least a blade engaged with a corresponding metal profile onto whose opposite ends hubs are inserted, which hubs are guided turnably through holes of the frame uprights of said shutter, and levers for actuating rotatingly said hubs, which levers are operatively connected to the handle of said shutter, characterized in that it has metal elements with longitudinal development and high mechanical resistance for connection between said levers and said profile, which elements are arranged through said holes and said hubs.
  • said figures show a high security shutter, for instance a window, with adjustable blades, globally referred to with number 1.
  • Window 1 comprises a frame 2 made up of crosspieces 3 connected to uprights 4 supporting adjustable blades 5.
  • Adjustable blades 5 are operatively connected to handle 6 by means of an actuating mechanism turning the reversible rotation of handle 6 into a reversible rotation of adjustable blades 5, from a closing position in which adjustable blades 5 are arranged in coplanar position inside the lying plane of frame 2 and with their top in contact with the base of the following adjustable blade 5, to an opening position in which adjustable blades 5 are arranged parallel to one another and extend transversally outside the lying plane of frame 2.
  • Each adjustable blade 5 is engaged by pressing with a corresponding metal profile 7, onto whose opposite ends hubs 8 guided turnably through corresponding holes 9 of uprights 4 are inserted.
  • each hub 8 extends basically along the longitudinal extension of profile 7, so as to create as a whole together with profile 7 an element extending transversally without interruptions between uprights 4.
  • Hubs 8 are connected to one end of corresponding levers 10, whose other end is hinged to rods sliding longitudinally inside corresponding uprights 4.
  • Rod 11 placed inside upright 4 carrying handle 6 receives its shifting movement from an engagement tooth 12 actuated by handle 6 and drags indirectly rod 11 placed in the other upright 11, the latter rod being connected through adjustable blades 5 to hubs 8 and levers 10.
  • Both rods 11 thus execute a simultaneous shift having the same size, which enables to synchronize the rotation of all adjustable blades 5.
  • Window 1 comprises metal elements 13 developing longitudinally and having a high mechanical resistance for connection between levers 10 of each adjustable blade 5 and the corresponding metal profile 7, said elements being arranged through hubs 8 and corresponding holes 9.
  • Metal elements 13 comprise self-threading screws, preferably made of hardened steel and preferably screwed onto opposite ends of an eyelet 14 of profile 7 having longitudinal development and half-circular section.
  • Eyelet 14 of profile 7 has inside a cut preventing rotating bar 15 extending between said self-threading screws.
  • Said cut preventing rotating bar 15 is again made of hardened steel.
  • Each profile 7 has such a tubular shape as to resist in an excellent manner to breaking, and comprises an outer portion 16 extending mainly in a basically orthogonal direction with respect to the side of blade 5 pointing outside, and an inner portion 17 extending mainly in a basically parallel direction with respect to the side of blade 5 pointing inside, and in particular outer portion 16 basically overlaps the outline of the outer side of blade 5, whereas inner portion 17 extends basically outside the bottom edge of blade 5.
  • Eyelet 14 is obtained in particular inside outer portion 16 of profile 7.
  • Inner portion 17 of profile 7 has a housing seat 18 of a seal 19 abutting against the inner side of the top end of adjacent blade 5 when blades 5 are in closing position, so as to create a watertight condition.
  • profile 7 has an inclined surface for water draining, if necessary slightly curved, having its origin in housing seat 18 of seal 19 and protruding from the outer side of blade 5.
  • Said rod 11 has at least a longitudinal slot 22 engaging in adjustable position with block 20.
  • Stiffening plate 25 is fastened to rod 11 through the same screws joining rod 11 to block 20.
  • window 1 the connection between uprights 4 and crosspieces 3 is carried out by means of angular plates 26.
  • the figures show by way of example the level side 27 of an angular plate 26 having parallel edges engaged into parallel troughs of guide 28 obtained along the outer side of the upper face of crosspiece 3, whereas the other level side 29 of angular plate 26 is fastened to the inner side of the face of upright 4 facing profile 7 by means of screws 57 engaging with longitudinal eyelets 58 obtained as one piece in the inner section of crosspiece 3.
  • Window 1 can make use of single span or double span uprights 4 in case of a very broad horizontal air gap of the window opening.
  • Single span upright 4 as shown in Figure 7c is made up of a first U-shaped profile 31 having engagement seats 34 obtained along its longitudinal edges, and of a second flat profile 32 closing the open side of first profile 31, having along its longitudinal edges engagement teeth 33 engaged with guides 34 through relative longitudinal sliding.
  • Double span upright 4 as shown in Figure 7a is made up of a first U-shaped profile 35 having first engagement seats 36 obtained along its longitudinal edges, of a second U-shaped profile 37, preferably identical to first profile 35, having second engagement seats 38 obtained along its longitudinal edges, and of a third flat profile 39 closing the open side of first and second profiles 35 and 37, having along its longitudinal edges two engagement teeth 40 and 41 engaged with first and second engagement seats 36 and 38 through relative longitudinal sliding.
  • Double span upright 4 as shown in Figure 7b is made up of a first U-shaped profile 42 having first engagement seats 43 obtained along its longitudinal edges, of a second U-shaped profile 44, preferably identical to first profile 42, having second engagement seats 45 obtained along its longitudinal edges, and of a third and fourth flat profile 46 and 47 closing the open side of first and second profiles 42 and 44, having along their longitudinal edges first engagement teeth 48 and 49 engaged with first and second engagement seats 43 and 45 through relative longitudinal sliding, and having further second cross teeth 50 and 51 for mutual engagement.
  • third and fourth profile 46 and 47 are identical and have on each of their faces second cross teeth 50 and 51 arranged in two pairs of teeth with different on-centers, so that second teeth 50 with smaller on-center of third profile 46 can engage with second teeth 51 with greater on-center of fourth profile 47, and on the other side second teeth 50 with greater on-center of third profile 46 can engage with second teeth 51 with smaller on-center of fourth profile 47.
  • Uprights 4 can thus be perfectly reversible.
  • Window 1 eventually enables closing of the horizontal air gap that might be present between last adjustable blade 5 and upper crosspiece 3 of the frame, thus ensuring a pleasant appearance.
  • a fixed blade 52 is used, which is housed between a guide 53 obtained on the outer side of the lower face of upper crosspiece 3, and a U-shaped guide 54 having an outer abutment side for seal 19 of profile 7 of adjacent adjustable blade 5.
  • Guide 53 has eventually on the ends of its base holes 55 so as to be fastened by means of screws 56 to frame uprights 4.
