Abstract

A Double Glazing Window Breaking Device, has a body (A), a hardened pointed rod (B), a spring (C), a retarding collar (D), a retarding nut (E), a plate (F), and is located and secured by means of surface (G), in a load bearing area of a Double Glazed window. The said device is operated by exerting a force on plate (F), causing rod (B) to penetrate the first pane of glass of the Double Glazed window causing it to fracture. <IMAGE>

Description

SPECIFICATION Double glazing window breaking device This invention relates to a Double Glazing Window Breaking device.
It has become apparent because of recent events, that Double Glazed Sealed units and windows constructed with them, and permanently fixed secondary Double Glazed windows, have proved almost impossible to break in the event of a person or persons wishing to evacuate a building or structure through the aforementioned window types.
These factors which contribute to this are: 1) The glass type used in the construction of the aforementioned window types has a greater thickness than the glass used in standard single glazed windows 2) The seals used in the construction of the aforementioned window types absorb some of the force when they are "shockloaded" thus rendering it less effective.
3) The area in which the aforementioned window types are "shock-loaded" is critical to the effective breaking of the said window types, and the public are not made aware of it.
4) The implement used to effect the "shock-loading" of the said window types is critical to the effective breaking of those said window types, and these types of implements are not readily available in the event of an emergency.
5. The "Thermal Insulation Barrier" presentin the said window types, absorbs a very high proportion of the force used in "shockloading" them. Thus making the "shock-loading" ineffective Because of the above factors a peron or persons find it almost impossible to breakthrough and evacuate through the said window types.
According to the invention there is provided a Double Glazing Window Breaking Device, comprising of an body, which provides means for securing the said device to the aforementioned window types by a form of adhesion.
A hardened Rod, one end of which is pointed to enable ease of penetration of the glass of the aforementioned window types, it being located within the Body. A spring located within the body to assist in the location and the action of the hardened rod. A retarder is located on the rod to assist in the location of the spring. A retarding nut to assist in the location of the rod and spring. A plate is located at the opposite end of the rod to the point and is used to receive a force sufficent deliver the pointed end of the rod onto and into the glass, of the said window types. The travel of the rod being perpendicular to the glass.
The said device is secured and located perpendicularly in one of the critical load bearing areas of the said window types.
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 the separate components of the Double Glazing Window Breaking Device.
Figure 2 shows the crossectional view of the assembled aforementioned device.
Figure 3 shows the assembled said device.
Figure 4 shows the side elevation of the said device as located on a Double Glazed Window.
Figure 5 shows the side elevation of the said device as it is operated, and illustrates the position of the rod.
Figure 6 shows in perspective the said device located on a Double Glazed Window.
Referring to the drawings, the Double Glazing Window Breaking Device comprises of a body (A), a hardened rod one end of which is pointed (B), a spring (C), a retardr (D), a retarding nut (E), a plate (F), shown in Fig. (1).
These are assembled as in Figs. 2, 3.
In order to locate the Double Glazing Window Breaking Device, an adhesive is applied to face (G), the means securing the said device perpendicularly to the Double Glazed Window, the said location Fig. (4), (6), being of perminant nature. The location of the said device is in any of the Double Glazed windows load bearing areas, for example one of the bottom corners. At this time the point of the rod is held adjacent to the surface of the first pane of glass in the Double Glazed window.
To operate the said device, a sharp force, is exerted on plate (F). This force being sufficient to propel the rod (B), in the direction (H), which is perpendicular to the Double Glazed window. This action causes the point of rod (B) to penetrate the first pane of glass in the Double Glazed window Fig. 5. The action of rod (B) in penetrating the glass in a load bearing area causes stress fractures to occur, and cracks to propagate throughout the first pane of glass. This effectively removes the "Thermal Insulation Barrier", which is a pocket of dry still air, and inconjunction breaks the seals which are the very foundations of the Double Glazed window. Thus rendering the first pane removable. Having removed the aforementioned factors 2, 5, (page 1), The remaining pane of glass can be "shock-loaded" effectively thus facilitating evacuation through the Double Glazed window.
By locating the device in the aforementioned area, factors 3, 4, (page 1) are overcome. By operating the device factors 2, 5, (page 1) are overcome. The overall action renders factor 1, (page 1) negligable.
