Description

Emergency hammers for crushing windows of vehicles

The present invention relates to an emergency hammer for shattering a vehicle, and particularly, in the case of securing an escape route by hitting a vehicle's window with a hammer in an emergency, the impact amount is obtained by propelling the hammer using the explosive gas of gunpowder. It is possible to crush large windows by using small force in case of emergency, so that even in case of combustor or elderly person, it is easy to crush the windows so that the emergency hammer for window shredding of the vehicle can be secured. It is about.

In the case of a large vehicle such as a bus or a van, there is usually a single door. If the door does not open or cannot be reached at the time of an accident, a window must be opened to escape from the accident vehicle.

However, in recent years, vehicles such as express buses are not designed to open the windows, and in the case of vans, the windows are too small to allow people to enter and exit.In this case, a hammer is provided to break the windows. Should be.

The window smashing hammer as described above is generally mounted on the inner wall of the vehicle, but as a further improvement, as shown in FIG. 1, a mounting structure of a hammer that can be operated by pressing an operation button is used. .

In the conventional hammer mounting structure as described above, the hammer 2 is supported by a spring 3 on one side of the center pillar 1 to be hinged by the coupling pin 4a and the bracket 4b, and the hammer 2 The upper side of the engaging jaw (5) is attached, it is mounted in a state in which the hook (6) connected to the actuator (7) is caught on the engaging jaw (5).

In the mounting state as described above, when an accident of the vehicle occurs, pressing the operation button (not shown) in the adjacent position of the occupant, the actuator (7) is operated after the overturn detection sensor detects the accident, the hook (6) While pushing the locking jaw (5) is released.

Therefore, the hammer 2 is operated by the coupling pin 4a as the axis under the force of the spring 3 to hit the window 8 to crush the window 8.

However, the conventional window shredding hammer as described above has to be provided with a strong spring because the breaking force for breaking the window is provided only by the force of the spring, and therefore the durability of the hammer itself is low, and in some cases it must be broken by manpower. However, in this case, a large force is required and there is a problem in that the combustor or the elderly are not easily broken.

The present invention is to solve the above-mentioned shortcomings, in breaking the window of the vehicle in an emergency, by using a small force to crush the large window, so that even the combustor or the elderly can easily crush the window It is intended to provide an emergency hammer for shattering a window of a vehicle to secure an escape route.

The present invention is located inside the piston is coupled to the position restoring means, the hammer is coupled to one side of the piston, the other side is equipped with a gunpowder, the hammer portion consisting of a cylinder is installed a cover for supporting the gunpowder; ; It is achieved by including a handle portion attached to the side of the cylinder.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a side view showing an embodiment of the emergency hammer for window fracturing of the vehicle of the present invention, Figure 3 is a cross-sectional view showing a hammer portion of an embodiment of the emergency hammer for window fracturing of the vehicle of the present invention, the present invention, the inside Piston 110 is coupled to the position restoring means 120, the hammer 130 is coupled to one side of the piston 110, the gunpowder 140 is mounted on the other side, the gunpowder 140 A hammer part (100) consisting of a cylinder (160) on which a cover (150) for supporting the arm is installed; It is characterized in that it comprises a handle portion 200 is attached to the side of the cylinder 160.

The cover 150 may be detachably screwed to reload the gunpowder 140, and the gunpowder 140 is a limfire-type tableting gun commonly used for construction purposes. It is preferable to use standardized gunpowder.

On the other hand, the position restoring means 120, the partition wall 121 is formed so that the piston 110 penetrates inside the portion where the hammer 130 of the cylinder 160 is installed, the piston 110 An installation groove 122 is formed in a portion into which the gunpowder 140 is inserted, and the elastic body 123 is coupled between the partition wall 121 and the installation groove 122.

In addition, it is preferable that the discharge port 161 is formed on the side of the portion of the cylinder 160 is mounted with the gunpowder 140, so that the smoke generated by the explosion of the gunpowder 140 is released.

Figure 4 is a cross-sectional view showing the operation during the explosion of an embodiment of the emergency hammer for window breakage of the vehicle of the present invention, the operation and effect of the present invention with reference to Figures 2 to 4 as follows.

As described above, in the present invention, in crushing a high-intensity window of the vehicle, by using the explosive gas of the gunpowder, when the hammer hits the window with a small force capable of igniting the gunpowder primer, the gunpowder ejects the gas, The hammer generates a large shock wave toward the window and breaks the window. The operation of the hammer is as follows.

That is, in an emergency, the passenger grasps the handle 200 of the hammer of the present invention and strikes the hammer part 100 against the window.

Then, a striking force is transmitted to the hammer 130 of the hammer part 100, and the piston 110 fixed to this hammer 130 is retracted, and the gunpowder 140 between this piston 110 and the cover 150 is carried out. Shock to the primer.

Thus, when the gunpowder 140 explodes, a sudden gas is generated while the charge is burned, and the pressure in the cylinder 160 rises rapidly, thereby causing the piston 110 and the hammer 130 fixed thereto to move toward the window. do.

In the above process, the hammer 130 is subjected to a strong impact force, the window is easily broken by this impact force.

When the window is crushed and the hammer 130 and the piston 110 move as shown in FIG. 4, the remaining gas of the explosive explosion is ejected by the outlet 161 of the cylinder 160, and the cylinder 160 The internal pressure drops.

Thereafter, the hammer 130 and the piston 110 are returned to their original positions by the position restoring means 120. The cover 150 is separated and the powder 140 is reinserted into the groove of the piston 110. Combining the cover 150 will be reusable.

On the other hand, when the gunpowder 140 is not loaded, it can be used in the same way as a conventional hammer.

The present invention as described above can be used to break a large strength window using a small force in the event of boarding of the vehicle, an emergency, even in the case of a burner or the elderly can easily break the window to secure an escape exit It is an invention that there is.
