<p>A child safety barrier with a door secured in a U-shaped frame has a locking device which cannot be operated by children. The locking device has an activation unit which, when receiving a signal from a signal generator, releases the locking device so that the door may be opened or closed, which, in one embodiment, must take place within 2-4 seconds of the point of time when the signal generator is activated. The activation device may be formed by a mechanical activation mechanism, while the signal generator may be a push-button, an electric voltage or a remote control using a connection of the type IR, Bluetooth or the like. In a preferred embodiment, the activation device is connected with a push/pull rod whose one end is connected with a relay, while its other end is connected with a movable post extending inside a column in the U-shaped frame to which the door is secured. The invention provides a child safety barrier having a locking device where the locking device of the child safety barrier may be opened without using hands, feet and/or legs.</p> |
