Abstract

A double glazing window breaking device comprising of mild-steel U-section fabricated from flat strip. The longer end 10 is reinforced on outer side 11 from mild-steel strip. The inner side of the longer end 10 a tool-steel ground point 12 is brazed. Between U-section 'arms' 13 is a removable safety guard 14. To remove safety guard 14 the top 15 is pulled upwards out of grip of U-section 'arms' 13. To secure device to window the outer side of smaller end 16 is adhered to glass 17 by double sided foamed adhesive tape 16. To operate device, the safety guard 14 is removed and the back of flexible longer end 11 is struck with hand causing the point 12 to penetrate the first pane of the double glazed window 17. <IMAGE>

Description

Ix)u & GtlAZIM3 wIMxM BRE### This invention relates to a double glazing window breaking device.
The double glazing window breaking device is beneficial if used on double glazed windows which have only top openers, which will restrict escape in the event of a fire occurring and trapping the occupants upstairs.
The double glazing window breaking device, consists of a mild-steel Usection, fabricated from flat strip. One end (the longer end) of the U-section is reinforced on the outer side with a (spot-welded) piece of mild-steel strip. On the inner side of the reinforced end, a toolsteel ground point is brazed, which will override the opposite shorter end of the U-section when the safety guard is removed and the reinforced side is struck with the palm of the hand.
The shorter end, on the outer side of the U-section is adhered securely to the bottom corner of the double glazed window with a double sided foamed adhesive tape to avoid misplacement of the device.
To cause the device to become operational, a metal guard is removed from between the U-section 'arms', therefore, the tool-steel ground point is ready to make contact with the first pane of the double glazed window.
The contact is achieved by striking the flat flexible side adjacent to the point with the palm of the hand, causing the point to penetrate and shatter the first pane of glass, which will then release the vacuum between the two panes, enabling the second pane of glass to be broken manually.
The metal guard is situated between the U-section 'arms' to prevent accidental operation of the window breaking device.
According to the present invention there is a double glazing window breaking device comprising of a mild-steel U-section, fabricated from flat strip.
On the inner side of the long end of the U-section a tool-steel ground point is brazed, which overrides the opposite smaller end of the U-section when in use, and on the outer side (flat side) of the long section, it is reinforced with a (spot-welded) piece of mild-steel strip.
There is a double sided foamed adhesive tape on the outer side of the smaller end, which sticks securely to the bottom corner of the window.
Accidental operation of the window breaking device may be prevented by a removable metal safety guard placed between the U-section 'arms'.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 shows in perspective, the double glazing window breaking device at a side angle with the safety guard in position.
Figure 2 illustrates the device against a pane of glass and without the safety guard. The device is ready to penetrate the pane of glass.
Figure 3 shows the device at a facing position revealing the adhesive tape. Again without the safety guard.
Figure 4 shows a side angle of the safety guard.
Figure 5 shows the back of the device with the safety guard in position.
Referring to the drawings, a double glazing window breaking device consists of a mild-steel U-section, fabricated from flat strip. The longer end 10 of the U-section is reinforced on the outer side with a (spot-welded) piece of mild-steel strip 11.
The inner side of the longer end 10 a tool-steel ground point 12 is brazed.
Between the U-section 'arms' 13 is a removable metal safety guard 14 which will prevent accidental operation of the window breaking device.
To remove the safety guard 14 the top of the guard 15 is pulled upwards out of the grip of the U-section 'arms' 13.
To secure the window breaking device shown in Fig 2 to the glass 17 in order to avoid misplacement, the outer side of the smaller end 16 is adhered to the glass 17 by double sided foamed adhesive tape 16.
To operate the device, the safety guard 14 is removed and the back of the flexible longer end 11 is struck with the palm of the hand causing the tool-steel ground point 12 to penetrate and shatter the first pane of the double glazed window 17.

Claims (6)

  1. aalMs
    A. A double glazing window breaking device comprising of a mild-steel U-section fabricated from flat strip. On the inner side of the longer end of the U-section, a tool-steel ground point is brazed. On the outer side of the longer section is reinforced with a (spot-welded) piece of mild-steel strip. There is a double sided foamed adhesive tape on the outer side of the smaller end of the U-section. There is a removable metal safety guard placed between the U-section 'arms'.
  2. 2. A double glazing window breaking device as claimed in Claim 1 wherein the outer side of the smaller end of the U-section is adhered to the glass by double sided foamed adhesive tape.
  3. 3. A double glazing window breaking device as claimed in Claim 1 or Claim 2 wherein the smaller end of the U-section is adhered to the glass. The U-section has a removable metal safety guard between the U-section 'arms'.
  4. 4. A double glazing window breaking device as claimed in Claim 1 or Claim 3 wherein there is a safety guard which when removed, the U-section is flexible, ready to operate by striking.
  5. 5. A double glazing window breaking device as claimed in Claim 1 or Claim 4 wherein the U-section becomes flexible on removal of the safety guard, and also reveals the tool-steel ground point which will now penetrate the first pane of the double glazed window when struck on the outer side of the long end of the u-section adjacent to the point with the palm of the hand.
  6. 6. A double glazing window breaking device substantially as described herein with reference to figures 1 - 5 of the accompanying drawings.
