<p>A child proof lock which has two parts (10, 12). The first part (10) is of strap-like contruction, is attachable to a surface at one end (18), has a shaped aperture (28) at the other, and has an elastic portion (16) between the two ends (18, 20). The second part (12) is also attachable to a surface and includes a rotatable mounted toggle (30). The toggle (30) is shaped so as to be able to pass through the aperture (28) in the first part (10) only when it has been correctly rotationally orientated. In use the first and second parts (10, 12) of the child proof lock are attached to opposite sides of a door opening in a relationship whereby the first part (10) must be expanded to allow the toggle (30) to pass through the aperture (28). To lock the device the toggle (30) on the second part (12) is correctly rotationally orientated, the first part (10) is expanded and the aperture (28) passed over the toggle (30). When the first part (10) retracts an abutment (32) on the first part (10) rotates the toggle (30) thus locking the device. To unlock the device the first part (10) is expanded using one hand and the toggle (30) is rotated using the other hand enabling the two parts (10, 12) to be disengaged.</p> |
