Many modern entrance doors need a power supply in the door leaf for electronic door locks, fingerprint scanners and other access systems or integrated lighting. In cooperation with SOMMER, Groke has developed a new system for the power supply of doors. This first of its kind comes without complex cabling or spring contacts that would be susceptible to wear, with power being supplied via the door hinges. The system is easily integrated into existing hinge systems – all they need is an
insulated support bolt. Conductive contact elements are integrated into the door leaf hinges and frame hinges in a manner that is space-saving and without any notable change to the design. Electrically conductive bolts transmit the current between the door leaf hinge and the frame hinge. The system works on the basis of "Plug and Play", i.e. individual elements contact automatically when the door leaf is mounted and no electrical installation work is required. If needed, data can also be transmitted. Thanks to the use of existing design elements, the cable is not noticeable and the mobility of the door leaf is not restricted by the cable sections. The power supply is retained when the door is open or closed and corrosion to conventional contact elements is eliminated. This system will be launched on the market by SOMMER in the future and offered to all interested door manufacturers. Advantages
