Abstract

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.

Claims

1. A child safety barrier (1) with a lock arrangement comprising a lock that may be activated by a foot, and wherein the lock is locked and unlocked by a mechanical auxiliary lock (8) which ensures in a locked state that the foot cannot activate the lock, wherein the foot pedal can be activated during a given interval of time after the mechanical auxiliary lock has been unlocked.

2. A child safety barrier according to claim 1, wherein the mechanical auxiliary lock may be unlocked by an electrical receiver (8a), when the receiver receives an electrical signal from a transmitter (9).

3. A child safety barrier according to claim 2, wherein the transmitter (9) is adapted to transmit an electromagnetic signal, such as an infrared beam to the receiver.

4. A child safety barrier according to claim 3, wherein the transmitter (9) is incorporated in a remote control unit.

5. A child safety barrier according to claim 4, wherein the remote control unit is of the hand-held type.

6. A child safety barrier according to claim 4, wherein the remote control unit is mounted on a wall.

7. A child safety barrier according to claim 6, wherein the transmitter continuously transmits electromagnetic signals to the receiver, and the auxiliary lock (8) is activated when the electromagnetic signals are interrupted.
