Abstract

Abstract A motor-driven electric cable reel assembly comprises a rotatable cable take-up drum (7), and an electric motor (2) for driving the drum (7) in its cable take-up direction. The cable reel assembly also includes a storage battery provided with a battery charger which is connected to the cable in a manner such that the battery is recharged when the cable is connected to an electric power source. Also provided is a switch arrangement (10) which is effective to stop the motor (2) in response to torque generated by the motor.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 85 words
A motor-driven cable reel assembly comprising a rotatable cable drum (7), an electric motor (2) which is effective in rotating the drum in a cable reel-in direction, a storage battery, and a battery charger which is connected to the cable in a manner to recharge the battery when the cable is connected to a source of current, characterized in that the cable reel assembly further comprises a motor-­control switch arrangement (10) which is intended to switch-­off the motor (2) in response to torque generated thereby.
Claim 2
Dependent Claim 85 words
A motor-driven cable reel assembly comprising a rotatable cable drum (7), an electric motor (2) which is effective in rotating the drum in a cable reel-in direction, a storage battery, and a battery charger which is connected to the cable in a manner to recharge the battery when the cable is connected to a source of current, characterized in that the cable reel assembly further comprises a motor-­control switch arrangement (10) which is intended to switch-­off the motor (2) in response to torque generated thereby.
Claim 3
Dependent Claim 50 words
A cable reel assembly according to claim 1, characterized in that the switch arrangement (10) is manually actuable (9) in a manner to start the electric motor (2) and is constructed to disconnect electric current to the motor (2) when the torque generated by the motor exceeds a predetermined value.
Claim 4
Dependent Claim 46 words
A cable reel assembly according to claim 1, characterized in that the switch arrangement (10) is intended to close the motor circuit when the motor torque lies beneath a given first value, and to break said circuit when the motor torque exceeds a second predetermined value.
Claim 5
Dependent Claim 37 words
A cable reel assembly according to claim 1, characterized in that the switch arrangement (10) is intended to close the motor circuit when the cable is disconnected from the external power supply, e.g. an electric wall socket.
Claim 6
Dependent Claim 58 words
A cable reel assembly according to claim 1, characterized in that the switch arrangement (10) includes an electric contact member (C) which is actuable by two stops (A,B) which are located in mutually spaced relationship on a rotatable side wall (8) of the reel, said stops (A,B) defin­ing limits to which the side wall (8) can be rotated.
Claim 7
Dependent Claim 25 words
A cable reel assembly according to claim 5, characterized in that the electric contact (C) of the switch arrangement (10) has a given, selectible inertia.
