PURPOSE: A device for helping wiring which is positioned at a corner of a sliding door is provided to reduce the increment for heating expenses caused when a door is not completely closed in wiring and reduce damage due to pests. CONSTITUTION: A device for helping wiring which is positioned at a corner of a sliding door comprises a triangle machine or a square machine(7), and a spring. The machine is mounted on a door(1) or the corner of the window. The spring generates tension between a door body and the machine. In case there is no electrical wire(5), the door is automatically closed by the spring and the self-weight. In case there is electrical wire, a space is formed as the electrical wire pushes the machine in closing the door. |
