Fixed glass breaker

Abstract

Disclosed is a glass breaking tool, and more particularly, to a fixed-type glass breaking apparatus that is usable in a fixed state. The fixed-type glass breaking apparatus for breaking tempered glass composing a window of a vehicle, the fixed-type glass breaking apparatus comprises an attachment device installed such that at least a part thereof is in surface contact with a surface of the tempered glass, and a damaging device mounted in the attachment device in a perpendicular direction to the surface contacted tempered glass surface to form a crack on the tempered glass surface.

Description

technical field [0001] The present invention relates to a tool for breaking glass, and more specifically, to a fixed glass breaking device that can be used in a fixed state. Background technique [0002] In some applications, it is necessary to provide a glass that is strong yet resilient to breakage. One such use is in cars, trucks, buses, trains and all kinds of ships. Glass for these vehicles should be able to withstand strong impacts and be resilient to damage. However, this feature is not necessarily preferred in all circumstances. For example, after an accident, the glass is preferably broken in order to enable the occupants of the accident vehicle to escape. This feature is especially important when the vehicle falls into water or encounters a fire. In this case, the glass must be broken so that the occupants can escape safely. [0003] Currently, tools such as a hammer are provided in order to enable passengers to break the glass of the vehicle. But passengers ...

Problems solved by technology

However, when an accident occurs in water, it may be difficult to open the window due to water pressure

[0004] Especially in an emergency, there will be a great danger when many people gather at the safety exit. Therefore, it is necessary to develop a glass breaking device that can break the glass and escape in a short time, for example, within 10 seconds.
