In conventional hinge systems, installing a surface-mounted door or hatch is often awkward. The hinge pin can only be pressed in if the door frame bracket and the door bracket are positioned precisely against each other. Since there are usually multiple hinges, this process must be performed on each one. Disassembly is also difficult. Depending on the installation situation, the hinge pin must be pulled up, down, or out to separate the door from the door frame. However, there is often insufficient space above or below the hinge.
The new, internal, and therefore invisible, hinge can be positioned on either the left or right side of the frame. To attach the door or hatch to the frame, the door assembly is placed onto the sliding plastic discs on the frame piece. Then, push it horizontally toward the hinge pin until the door clicks audibly. This clip-on mechanism distinguishes the new hinge from conventional ones. The hinge pin is installed within the frame piece and therefore does not need to be moved up or down. The guide automatically moves the assembly into the correct position. With slight pressure against the door, the hinge parts lock and securely connect to the frame. No tools are required, and the door does not need to be closed. As soon as the door is opened, a secure connection is established between the door and the frame. The door or hatch can be removed just as easily. To do this, simply pull the latch on the door assembly to unlock the door. In this open position, it is not necessary to hold down the latch because it locks into place. Now the other hinges can be opened one after the other in the same way. The door or hatch can then be removed quickly and easily.
Furthermore, the hinge has been successfully tested for shock and vibration resistance according to DIN EN 61373 Cat. 1B and tested in continuous operation.
