Background
In general, since various disaster situations such as earthquake, fire, flood, traffic accident, etc. are not prevented, it is required to be able to rapidly escape in emergency according to various disaster situations, and in case of difficulty in escaping, it is required to provide rescue signals so that rescue activities can be more rapidly performed outside.
For this reason, there have been conventionally provided multifunctional hammers which are installed in vehicles or buildings to escape in emergency when a disaster occurs.
As an example, korean patent No. 10-1359709 discloses a safety device for emergency escape, which includes: the hammer component can form an escape opening by striking glass when the public transportation means has an emergency; a support unit for supporting the hammer part, including a body provided in a vehicle interior of the mass transit means, a hanging portion formed to protrude from the body, fixing the hammer part to the body, a switch provided to the body for detecting whether the hammer part is fixed to the body by the hanging portion, a warning unit for displaying the hammer part as an audible signal or a visual signal when the hammer part is separated from the body, and a transmitter for transmitting a wireless signal when the hammer part is separated from the body; and a main manager including a housing provided in a vehicle adjacent to a driver, a receiver built in the housing for receiving a wireless signal transmitted from the transmitter, a central processing unit for processing the signal received from the receiver, and one or both selected from a speaker and a light-emitting lamp for notifying the driver when the wireless signal is received by the receiver.
However, in the case of the emergency escape safety device, since the warning unit, the receiver, and the like are not driven when the discharge of the electric power occurs, it is difficult to grasp the buried position of the buried person buried in the building or the like when the situation is in a disaster for a long time.
That is, the buried person needs to shout or knock the metal to inform the outside of his own death, and the outside uses a search dog, a thermal imaging detector, etc. to search for the buried person, and the physical strength of the buried person is lowered with the lapse of the optimal rescue time, so that there is a problem that it is difficult to request rescue.
The foregoing background art or the prior art is only for aiding in understanding the technical meaning of the present invention, and is not meant to be a technology known in the art to which the present invention pertains before the present invention is applied.

The second power generating devices 324 are formed in plural and inserted into the through center portion of the first power generating device 322, and slide along the inner surface of the first power generating device 322 to generate a predetermined frictional force, thereby generating frictional electric energy due to the difference in the frictional electric sequence value.
The second power generating device 324 may be formed of Polydimethylsiloxane (PDMS), but is not limited thereto.
In the case of using the safety hammer of the present invention for striking an external structure or equipment, when the position of the handle 300 is changed for striking, such second power generating equipment 324 slides along the first power generating equipment 322 in response to the changed position change and generates frictional power.
The second insulating member 326 surrounds the outer surface of the first power generating equipment 322, preventing the generated electric power from being temporarily transferred to the handle body 310 side.
In this case, the heating element 340 formed of a plurality of heating wires may be formed at the second insulating member 326, but the heating element 340 is not limited thereto, and may be formed at an outer surface of the second insulating member 326.
The heating element 340 may be electrically connected to the electrode portion 328, and heat may be generated by the electrode portion 328 under the control of the control portion 220.
On the other hand, the first power generating device 322 and the second power generating device 324 of the present invention may have a saw tooth shape, a sprocket shape, a gear shape, or the like, so that the friction surfaces between them can be positively increased to improve the efficiency of electric power generation, and the protrusions and the protruding grooves in the form of embossments are formed along the circumferential surface.
The electrode portions 328 are coupled to both end portions of the first power generator material 322, are coupled to the surface of the first power generator material 322 or the power generating electrode patterned on the first power generator material 322, are electrically connected to the coupling block 312, and can supply the generated electric energy to the rechargeable battery 230.
The opening/closing cover 330 is coupled to the other side portion formed at the handle body 310, in other words, to the cover fixing portion 316 formed at the rear-side end portion, and a contact portion 336 electrically connected to the cover fixing portion 316 is formed at the front-side end portion.
In this case, the contact portion 336 may include a fixing flange so that the coupling between the switch cover 330 and the handle body 310 may be achieved, and may be constituted by a conductive plate inserted into the outer circumferential surface of the fixing flange.
Also, the switch cover 330 includes: a first switch 332 for generating a control signal for applying a power supply required for driving the light emitting unit 240 and the transmitting unit 250, and transmitting the control signal to the control unit 220; and a second switch 334 for transmitting a control signal for generating a rescue request signal regarding whether the light emitting part 240, the transmitting unit 250, or the heating element 340 is driven or not.
Among them, the second switch 334 may be formed in plurality so that control signals for controlling a plurality of rescue request units (the light emitting part 240, the transmitting unit 250, the heating body 340) may be generated, but is not limited thereto.
The above description is merely illustrative of the technical idea of the present invention, and it is possible for those skilled in the art to which the present invention pertains to modify and deform the present invention without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are for explaining the technical idea of the present invention, and are not for limiting the present invention, and the scope of the technical idea of the present invention is not limited to such embodiments. The scope of the present invention is explained by the following claims, and all technical ideas within the scope equivalent thereto are included in the scope of the present invention.
