Definitions

  • the present invention relates to a closure device for windows and doors, particularly shutters, including a lock connected to a lower portion of the window or door.
  • Closure devices produced hitherto for shutters or for metal doorways with doors which pivot about intermediate horizontal axes include a lock fixed to the bottom of the door and adapted to drive a pair of horizontal slidable rods engageable in suitable seats formed in the frame to lock the door in the closed position.
  • the object of the present invention is to provide a closure device of the type specified at the beginning of the description which has a considerably improved ability to resist any attempts to force the window or door open.
  • this object is achieved by virtue of the fact that the lock drives a hook-like locking element which projects vertically from the lower portion of the window or door, the locking element being movable between a first position for its insertion in a fixed seat which faces the lower portion of the window or door and a second position in which the locking element engages an abutment of the seat in order to prevent the opening of the window or door.
  • the window or door is restrained frontally by virtue of the presence of the hook-like locking element, so that any attempt to force an entry is made more difficult.
  • the fixed seat preferably comprises a cavity in the sill of the shutter with an aperture at the level of the sill for the insertion, by the downward movement of the shutter, of both the locking element and a security portion of the lock which projects vertically from the shutter.
  • the security portion thus cooperates with the locking element to prevent it from coming out of the seat laterally and therefore increases the security of the device.
  • a shutter or roller shutter is generally indicated 10 and is provided with a lower portion 10a to which is fixed a lock 12, for example of the lever type, which, in known manner, drives two horizontal rods 14 adapted to engage suitable lateral seats (not shown) provided in correspondence with the jambs of the shutter.
  • the lock 12 includes a bolt 16 to which is fixed a locking element 18 provided with guide slots 20 for enabling it to slide transversely relative to pins 22 fixed to the lock 12.
  • the locking element 18 is in the form of an L-shaped hook and has a vertical rod-like portion 18a and an end portion 18b which is at 90 o to the rod-shaped portion 18a.
  • the lock 12 has a tubular appendage 13 of quadrangular cross-section which projects below the edge B of the shutter 10 and within which the rod-shaped portion 18a of the locking element 18 can slide transversely.
  • the dimensions of the tubular appendage 13 and the rod 18a are such as to enable the locking element 18 to be guided in its sideways movement, as will become clear from the following description.
  • a sill P which faces the edge B of the shutter and defines a seat 26 for housing and retaining a hollow metal body 28 with an upper wall 28a which is substantially flush with the sill P.
  • the hollow body 28 is provided with triangular lateral appendages 30 which cooperate with the material C of the sill P, (for example cast concrete) in order to prevent the hollow body 28 from coming out of the sill P.
  • the upper wall 28a of the hollow body 28 has a rectangular aperture 32 whose shape corresponds substantially to that of the tubular appendage 13 of the lock 12.
  • the lock 12 is open, with the locking element 18 and the tubular appendage 13 projecting frontally from the edge B of the lower portion 10a of the shutter.
  • the tubular appendage 13 and the locking element 18 enter the aperture 32 of the hollow body 28 which is fixed to the sill P ( Figure 2).
  • the operation of the lock 12 by means of a suitable key causes both the sliding of the rods 14 in opposite directions and the transverse sliding of the locking element 18 which is attached to or integral with the bolt 16 ( Figure 3).
  • This transverse movement causes the end portion 18b of the locking element 18 to be inserted in the undercut beneath the upper wall 28a of the hollow body 28, preventing the raising of the shutter 10.
  • the tubular portion 13 of the lock 12 prevents any movements of the shutter due to an attempt to force it open by trying to move the lower portion 10a of the shutter 10 sideways to release the hooked end 18b of the locking element 18 from its engagement with the upper wall 28a of the hollow body 28.
  • two lateral notches 15 and 17 of the locking element 18 cooperate with fixing pins F of the lock 12 to increase the security of the lock against a forced entry.
  • the hollow body 28 has a shaped closure plate 36 which is slidable within the body and has a raised portion 36a whose shape corresponds to that of the rectangular aperture 32.
  • the plate 36 is urged upwards by a helical spring 38 interposed between the plate and a bottom wall 40 of the hollow body 28. It is clear that, when the locking element 18 is inserted in the aperture 32, the shaped plate 36 is pushed downwards against the action of the helical spring 38.
  • Figures 4-7 show a second embodiment of the device according to the invention, in which elements similar to those shown in Figures 1-3 are indicated by the same reference numerals.
  • This embodiment of the device is particularly suitable for use with doors which pivot about intermediate horizontal axes.
  • the lower portion of such a door is indicated 40 and, in the closed configuration, its lower edge B faces the sill P.
  • the levers of the lock which are of known type, are indicated 43.
  • the means 41 for causing the vertical sliding of the locking element 18 comprise a sprocket 45 which is mounted in the lock for rotation about an axis X-X perpendicular to the direction of sliding of the bolt 16, and is adapted to cooperate with a set of teeth 47 provided on the side of the locking element 18.
  • a retaining member 48 is interposed between the pin 45a of the sprocket 45 and the lock and comprises a ball 48a which is acted upon by a compression spring 48b and is adapted to cooperate with a hemispherical seat 49 formed in the pin 45a so as resiliently to keep the locking element 18 in a raised position.
  • the pin 45a of the sprocket 45 also has a central hole of polygonal cross-section for enabling the insertion of an end 50 of a releasable control lever 51.
  • a spring 53 is interposed between the guide 42 and the locking element 18 for urging the locking element 18 resiliently towards a side wall of the guide 42 adjacent the sprocket 45.
  • the locking element 18 is fast with the lock 12 both by virtue of the engagement between the end of a recess 55 of the locking element and a corresponding pin 56 of the bolt 16, and because of the engagement of the notches 15 and 17 of the locking element 18 with the fixing pins F of the lock 12.
  • FIG. 8-9 is a variant of the first embodiment ( Figures 1-3), in which the tubular appendage 13 of the lock 12, which projects below the edge B of the shutter 12, has been replaced by a vertical pin 24 which projects below the lower edge B of the shutter and is adapted to cooperate with a circular hole 34 formed beside the rectangular aperture 32 of the hollow body 28.
  • the solution relating to this embodiment may be used to advantage for normal shutters and for doors which pivot about horizontal axes, with the advantage that there are no elements projecting from the lower edge of the shutter and greater security against forced entry is ensured.
