PURPOSE: A device for preventing a window from getting derailed is provided to prevent the derailment of a window by guiding the window to a window frame. CONSTITUTION: A device for preventing a window from getting derailed comprises a support block(100), a coupling block(200), and an elastic member. The support block is protruded upward and has a first guide groove(101) and a first support rod. The first guide groove corresponds to a guiderail formed in the inner top of a window frame. The support block is inserted into one end of the top of the window frame. The coupling block is protruded downward and has a second guide groove(201) and a second support rod. The second guide groove corresponds to the guiderail. The elastic member is coupled to the first and second support rods and supplies elastic force to the coupling block so that the coupling block can be protruded upward when the coupling block is coupled to the support block. |
