<p>A locking mechanism for a child safety barrier (1 ) may be activated by a foot pedal (6) which can only be operated when an auxiliary lock (8) has been activated. The auxiliary lock (8) is formed by a mechanical unit, which has an electrical receiver (8a) which, when receiving an electrical signal, e.g. an electromagnetic signal from a transmitter (9), can activate the auxiliary lock (8), following which the foot pedal (6) may be activated. The transmitter (9) may be incorporated in a remote control unit of the hand-held type, or it may be mounted on a wall, where an adult can activate the transmitter, e.g. by an elbow. The transmitter may also be a unit which continuously transmits electromagnetic signals which activate the auxiliary lock when they are interrupted.</p> |
