Abstract

The present invention relates to a glass breaking device for emergency escape which can easily break glass without applying force. The glass breaking device comprises: a container installed adjacent to glass so that an opened surface can face the glass, and containing explosive and a primer to detonate the explosive therein; a cover member for sealing the opened surface of the container, the cover member being made of a material easily breakable by explosion of an explosive; a plurality of metal balls which are inserted between the explosive in the container to pop out through the opened surface of the container during the detonation of the explosive and destroy the glass; and an ignition switch for actuating the primer. The glass breaking device detonates the explosive via pressing of the ignition switch and then the metal balls pop out from the container and the metal balls strike the glass to break the glass.

Description

[0001] Emergency escape glass breaker for car [0002]

And it is an object of the present invention to provide a glass breaker for emergency escape of automobiles, which can easily break glass by simple operation so that a passenger can escape quickly in an emergency.

In practice, not all of the vehicles are provided with a hammer, and even if a hammer is provided, it is not easy for passengers, such as an elderly person or a woman, to swing the hammer in a narrow space of the vehicle to destroy the glass.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a glass breaker for emergency escape of automobiles, which can easily break glass by simple operation, .

 A container installed adjacent to the glass so that an open side thereof is opposed to the glass, and a primer for detonating the explosive and the explosive therein is accommodated in the container; A cover member for sealing an opening face of the container, the cover member being made of a material that can be easily broken by explosive explosion; It is inserted between the gunpowder filled in the inside of the vessel,

A number of metal balls that destroy the glass; And an evacuation switch for operating the primer, according to the present invention.

Preferably, the detonating switch is a piezoelectric switch, and the container is fixed to the vehicle body by a fixing bracket made of a flexible material. When the ignition switch is pressed, the gunpowder explodes, the metal balls pop out of the container, and the protruding metal balls strike the glass and destroy it. Therefore, the glass can be easily destroyed without applying any extra force. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

An apparatus for breaking glass for emergency escape according to an embodiment of the present invention is shown in Figs. 2, a glass breaker according to an embodiment of the present invention is installed to face one side of a door glass, and includes a container, a cover member, a plurality of metal balls, Switch.

As shown in Fig. 3, the face opposed to the door glass of the container is open, and the open face is sealed by the cover member. Inside the vessel are guns and detonators. The container is made of a metal material with high strength so as not to be damaged by explosive explosion, and the cover member is made of a thin synthetic resin material

. The container is welded to the door chassis by a fixing bracket. At this time, the fixing bracket is preferably made of a flexible material so as to be bent in a direction perpendicular to the glass.

Metal balls are inserted between gunpowder housed in a container. The detonation switch is a piezoelectric switch connected to the primer through the electric wire, and is installed at a position where the occupant can easily find it. This piezoelectric type switch is a well known type widely used for a normal lighter, and when the switch is pressed, the flame is discharged at the end of the electric wire.

In the emergency break glass breaker 4 according to the embodiment of the present invention, when the occupant presses the detonation switch, the explosive explosion causes the metal balls inside the container to strike the glass and destroy it.

That is, when the passenger pushes the ignition switch, the flame is discharged at the end of the electric wire connected to the primer, so that the primer explodes, and the primer explodes by the explosion of the primer. By the explosive force of the gunpowder, the cover member is broken and a plurality of metal balls are repelled out of the container through the opening face of the container. Bouncing metal balls strike the glass and destroy it. At this time, it is preferable that the door glass which is broken by the metal balls is glass which is treated so that the entire glass is destroyed even if a part of the glass is impacted.

On the other hand, if the reaction force generated upon explosive explosion is too large, the reaction brace detaches the fixing bracket from the chassis, and the container or the metal balls may cause injury to the occupant. Therefore, when the fixing bracket is made of a flexible material, the fixing bracket absorbs the reaction force while being bent as shown by a two-dot chain line in FIG. 4, thereby preventing the above phenomenon.

Thus, when the glass is broken by the hitting of the metal balls, the occupant can escape through the installation space of the glass. In this embodiment, the case where the glass breaker is installed on the door glass is shown, but the case where the glass breaker is installed on the windshield glass or the rear glass may be sufficiently considered.

An apparatus for breaking glass for emergency escape according to an embodiment of the present invention is shown in Figs. 2, a glass breaker according to an embodiment of the present invention is installed to face one side of a door glass, and includes a container, a cover member, a plurality of metal balls, Switch.

As shown in Fig. 3, the face opposed to the door glass of the container is open, and the open face is sealed by the cover member. Inside the vessel are guns and detonators. The container is made of a metal material with high strength so as not to be damaged by explosive explosion, and the cover member is made of a thin synthetic resin material

. The container is welded to the door chassis by a fixing bracket. At this time, the fixing bracket is preferably made of a flexible material so as to be bent in a direction perpendicular to the glass.

Metal balls are inserted between gunpowder housed in a container. The detonation switch is a piezoelectric switch connected to the primer through the electric wire, and is installed at a position where the occupant can easily find it. This piezoelectric switch is a conventional lie

On the other hand, if the reaction force generated upon explosive explosion is too large, the reaction brace detaches the fixing bracket from the chassis, and the container or the metal balls may cause injury to the occupant. Therefore, when the fixing bracket is made of a flexible material, the fixing bracket absorbs the reaction force while being bent as shown by a two-dot chain line in FIG. 4, thereby preventing the above phenomenon.

Thus, when the glass is broken by the hitting of the metal balls, the occupant can escape through the installation space of the glass. In this embodiment, the case where the glass breaker is installed on the door glass is shown, but the case where the glass breaker is installed on the windshield glass or the rear glass may be sufficiently considered.

The present invention relates to an apparatus for destroying a glass so that a passenger can escape from the automobile in an emergency.

In a typical automobile, a passenger boarded or gets off the vehicle through the door. However, in the event of a fire in a car caused by an accident, or in the event of a car falling into a river, the passenger must escape quickly from the car in order to protect his or her life and body. However, since the door is deformed due to an impact at the time of an accident, the door may not be opened,

If the door is not opened by the water pressure when the vehicle falls in the river, the passenger can not escape from the vehicle and can not escape from the vehicle.

As shown in FIG. 1, in recent years, there has been an increase in the number of cases where a hammer capable of breaking the door glass is provided at a position adjacent to the door. That is, when an emergency escape is needed, the occupant can use the hammer provided to break the door glass and escape through the broken glass space.
