Abstract

A child safety gate having a locking device and a flexible retractable barrier sheet is disclosed. The locking device comprises a locking means having at least a locked position and an unlocked position. The locking means is configured to in its locked position prevent further extraction of the flexible retractable barrier sheet, and the locking means is configured to in its unlocked position allow at least extraction of the flexible retractable barrier sheet. Further, the locking device comprises a timer means configured to upon activation let a delay time elapse and then bring the locking means into its locked position.

An advantage of the locking device is that it provides safe operation of a child safety gate by automatically locking the locking device after a delay time has elapsed.

Claims

1. A child safety gate comprising a locking device and a flexible retractable barrier sheet, said locking device comprising

(a) a locking means having at least a locked position and an unlocked position, wherein the locking means is configured to in its locked position prevent further extraction of the flexible retractable barrier sheet, and wherein the locking means is configured to in its unlocked position allow at least extraction of the flexible retractable barrier sheet, and

(b) a timer means configured to upon activation let a delay time elapse and then bring the locking means into its locked position.

2. The safety gate according to claim 1, wherein the timer means comprises mechanical delay means.

3. The safety gate according to claim 2, wherein said delay means comprises a delay peg, a delay socket, and delay substance between the delay socket and the delay peg.

4. The safety gate according to claim 3 wherein the delay socket has a closed bottom and an upper opening adapted to receive the delay peg.

5. The safety gate according to claim 3, wherein the delay substance is high-viscous grease.

6. The safety gate according to claim 1, wherein the timer means is electronic.

7. The safety gate according to claim 1, wherein the locking means is actuated by a mechanically controlled lock actuator.

8. The safety gate according to claim 1, wherein the locking means is actuated by an electronically controlled lock actuator.

9. The safety gate according to claim 2, wherein the locking means and the timer means are integrated into a mechanical assembly.

10. (canceled)

11. A method for closing a child safety gate, comprising the steps of bringing a locking means for a safety gate into its unlocked position, activating a timer means, pulling out a flexible sheet, and attaching the flexible sheet to a locking trim.
