Definitions

  • the present invention broadly relates to a security device for anti-intrusion closure of window and door frames, and in particular, to a bolt-type device for securing window and door frames such as windows, French windows, and the like.
  • latches As is known, windows, French windows and the like window and door frames are equipped with a vast variety of latches, all. of which adapted to be worked from the inside to fasten and unfasten the window and door frame as necessary. On two-casement windows, these latches are usually arranged to cooperate with a striker plate mounted on the casing adjacently to the commissure of the wings of the casing when in the shut position.
  • Such latches perform satisfactorily so long as the reason for shutting a window is weatherproofing, but offer low resistance to tampering by anybody determined to break into a house and commit theft.
  • the repair personnel sent to restore a breached window and door frame invariably find that especially the striker plate of the latch has been uprooted by prying with a crowbar or shattered by hammer and chisel.
  • a number of devices have been proposed for defeating unauthorized entry attempts, such as proximity sensors and vibration detectors, as well as generic robbery alarms.
  • the underlying problem of this invention is to provide a security device which can overcome the above limitations of the prior art.
  • a security device of the bolt type for anti-intrusion closure of window and door frames such as windows, French windows and the like, characterized in that it comprises a rectilinear guide, an eye, a U-iron having a first arm sliding engaged into the guide and a second arm which can be inserted into the eye, and removable stopping means for holding the second arm in the position inserted into the eye.
  • a security device of the bolt type according to this invention is generally shown at 1.
  • the security device 1 is for application to a window and door frame 2, shown in dash-and-dot lines, which may be a window having two wings 3 and 4 hinged to a casing 5.
  • This bolt security device 1 comprises a rectilinear tubular cylindrical guide 6 having a vertical axis a-a.
  • the guide 6 comprises a tubular section 7 cut from pipe stock and welded onto a baseplate 8.
  • the baseplate 8 is attached to the window wing 3 by means of screws 8a.
  • a bearing bush 9 is mounted fixedly in the bottom portion of the tubular section 7.
  • the security device 1 further comprises an eye 10, being a short cutting of pipe stock 11 and having an axis b-b.
  • the eye 10 is welded onto a respective baseplate 12.
  • This baseplate 12 is attached to the other wing 4 of the window by means of screws 12a.
  • the pipe cutting 11 has a lead-in formation 11a at its top end.
  • the axis of the guide 6 and that of the eye 10 would be set apart a predetermined distance I, e.g. 65 mm.
  • the security device 1 also comprises a U-iron 13, which may be obtained by hot bending a length of steel wire having a predetermined diameter D, e.g. 10 mm.
  • the U-iron 13 has a first arm or guiding arm 14, and a second arm or working arm 15, the axes of these arms extending parallel to each other at the distance I from each other.
  • the two arms 14 and 15 are joined to each other in the U-shape by an intermediate section 16, which section forms a handgrip 17 for operating the U-iron.
  • intermediate section 16 is shaped at a circular arc lying in a perpendicular plane to the plane that contains both wings. It thus forms a bridge clearing any existing latches on the window and door frame.
  • the U-iron 13 is oriented to describe a reversed "U".
  • the first arm 14 is guided in the guide 6. More precisely, it is guided at the bottom in the bush 9, and is provided at the top with a collar 18, which collar is made integral to the arm, for example by welding, and which arm is arranged to slide inside the tubular section 7.
  • the first arm 14 includes a limit stop 14a in the form of a screw 14b engaged in a threaded blind hole 14c in the bottom end of the arm 14. This limit stop 14a will abut against the bush 9 upon the arm 14 reaching its upward limit end. In the opposite direction, a limit stop 14d is provided by the intermediate section 16 abutting the bush 9 when the first arm 14 reaches its downward limit end.
  • the second arm 15 can be engaged in the eye 10 against the bias of a resilient means 19.
  • the resilient means 19 comprises a spring 20 mounted over the first arm 14 and held between the bush 9 and the collar 18 to constantly bias the U-iron 13 upwards.
  • a releasable stopping means 21 holds the second arm 15 firmly inside the eye 10 in contrast with the bias of said resilient means 19, after the second arm is inserted through the eye 10.
  • the stopping means 21 comprises an equalizer 22, which is hinged to the free end 24 of the second arm 15 by means of a pin 23, and housed inside a slit 25 formed in the second arm 15.
  • the equalizer 22 can be moved between a substantially horizontal position projecting from the second arm 15 and a substantially vertical position recessed into the slit 25.
  • the equalizer 22 attains and maintains the projecting position naturally by gravity, but must be moved manually into the recessed position.
  • a jutting end 26 of the equalizer 22 provides a stop 27 adapted to abut the eye 10, while the other end 28 of the equalizer 22 reacts against the bottom 29 of the slit 25.
  • the second arm 15 is engaged in the eye 10 and held therein against the bias force of the spring 20 by the stop 27 abutting the eye 10.
  • the two wings 3 and 4 are fastened together by the U-iron 13, more precisely by the intermediate section 16 bridging the distance between the guide and the eye to lock the wings securely together.
  • the U-iron is pushed down (see arrow F1), against the bias of the spring 20, with one hand, and the equalizer 22 is brought into its recessed position into the slit 24 with the other hand (see arrow F2). Thereafter, the one hand is taken away from the U-iron, to release it and allow the force of the spring 20 to repel it upwards along the direction of arrow F until its limit stop 14a abuts the bush 9 (see Figure 3).
  • the second arm 15 is fully disengaged from the eye 10, and the equalizer 22 allowed to resume its horizontal position by gravity.
  • the wings can be opened and, if desired or necessary, the U-iron 13 can be turned aside, approximately a half-turn to a position close against the first wing.
  • the U-iron 13 is moved down against the bias of the spring 20 in the direction of arrow F1 as previously explained.
  • the second arm 15 will be again engaged in the eye 10.
  • the equalizer 22 is moved by the eye in its recessed position inside the slit 24, against its weight.
  • the device is described as incorporated to a two-wings window. In the instance of a single wing window, however, the device would be mounted between the wing and the casing, e.g. with the guide attached to the wing and the eye to the casing.
  • a major advantage of the device according to this invention is that it can protect a window and door frame to which it is incorporated against attack with such standard housebreaking tools as crowbars, prying levers, hammers and chisels.
  • Another advantage is that it also protects a window and door frame against attack by trick, since none of the actions required to open it can be applied in a coordinated fashion.
  • this security device is quite simple, no minor advantage for a device that is to be manufactured in very large volumes.
  • the device of this invention is quick to apply or retrofit to any window and door frame, including preinstalled ones.
  • inventive device features ergonomic design for the easy operation of the handgrip part, and the possibility to apply it to window and door frames that already mount latches of various description, which advantages are both inherent to that the intermediate section of the U-iron is a bridging configuration.
  • the life of the device according to this invention is practically unlimited, with no need for maintenance or servicing, and in any case, it is never less than the life of the window and door frame.
