BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a barrier gate of the type, that includes a frame which is secured in an opening such as a doorway or a staircase so as to seal off the opening, and an openable gate with a locking mounted in the frame for locking the gate in a closed position.
2. The Prior Art
An example of such a child safety gate is known from GB-A 2 226 845. A disadvantage is that the lower corner of the gate is not fixed in the locking position and Is deflectable.
SUMMARY OF THE INVENTION
This problem is solved by a child safety gate according to the invention which includes a locking member with an operation handle at the upper member of the gate for the activation of an engaging part at the lower member of the gate, the engaging part being designed for engaging the lower member of the gate which is designed for receiving the engaging part. Hereby a safe fixation of the lowermost corner of the gate is obtained. It is understood that of necessity other looking devices can be fixed to the top corner of the gate, e.g., activated through the same operation handle.
In a simple manner the locking device is designed with an operation handle which is downwardly loaded with a spring, i.e., when opening the gate it is to be pulled upwards. This ensures an easy handling for adults combined with it being a difficult movement, if not even an impossible one, for small children to operate. At the same time it is possible to provide an extra security through a heavy spring load, which only can be overcome by an adult person.
The locking device is preferably fixed to the upper member of the gate, with the operation handle below the member and at a distance such that an adult person, with the palm of his hand on the upper member, can nevertheless reach below the operation handle and activate it with his fingers. This results in an operation that is easy to accomplish and a simple construction.
The engaging part is in a particularly simple manner formed at the end of a bar connected to the operation handle and where the end extends through the introduction in the upper member of the gate and can go into a locking engagement with a lock hole on the top side of the lower member of the gate frame. Hereby a safe locking of the lowermost corner of the gate is achieved.
In order to unload or as a stop for the operation handle, the bar is designed with a stopping means for co-operation with the top side of the lower member of the gate frame for determination of the extreme position of the bar. This gives a simple construction as the operation handle in this case does not need to be designed with proper stops.
Alternatively, the engaging part can be shaped as a fork fitting that grips around the top side of the lower member of the frame, which also provides a safe fixation.
A particularly simple embodiment is achieved by forming the fork fitting so that it also grips around the lower member of the gate and is guided thereon. Hereby extra equipment for guiding the fitting is avoided.
The connection between the operation handle and the engaging parts does not necessarily have to be a rigid connection, but could be a wire, a string, a strap or the like, and that the engaging part is spring-loadedly arranged for locking engagement in the lower member of the gate. In such a case the guidance is suitably hidden away in a tube with a view to the child's safety.
A particularly preferred embodiment of the locking device includes a U-shaped part fixed straddling on the upper member of the gate, and the operation handle extends up between the sides of the U-shaped part, and a spring means is placed between the lower side of the upper member of the gate and the top side of the operation handle. This construction is simple and easy to mount and easy to operate but foremost child proof.
In barrier gates of the type where a fixed grid piece is present at each side of the gate, the operation handle can be designed in a U-shape with an elongation beyond the front edge of the gate intende
