    摘要: The present invention discloses a portable emergency escape device comprising a casing, a drum rotatably installed inside the casing and around which a wire is wound, a reduction gear connected to the drum, a DC motor having a rotation shaft connected to the reduction gear, a safety belt worn by a user, a braking resistor for determining a descent speed, and a constant speed control unit connected to the braking resistor. The braking resistor is connected between both ends of a power input terminal of the DC motor, and the braking resistor can control a resistance value. And, the constant speed control unit changes the resistance value of the braking resistor in response to the user's weight to maintain the descent speed constant regardless of the user's weight.

    摘要: The present invention disclosed a elevating cable reel of single-layer winding type comprising; a main body installed on a ceiling or wall or a support of a predetermined shape and having a storage space therein; a drum rotatably accommodated inside the main body, and having a hollow therein, and a power cable being wound around a circumferential surface thereof; a driving motor disposed in the hollow to provide forward/reverse rotational force to the drum; a slip ring installed on a part of the drum to receive commercial power in a contact manner; and an elevating body suspended from the lower end of the power cable and installed to be elevated up and down. And, the power cable is wound in a single layer on the circumferential surface of the drum to prevent heat generation due to eddy current.
