Definitions

• This invention concerns a protection device to be used especially in powered closing systems such as gates, automatic barriers, rolling shutters, sectional doors and the like and managed so as to avoid collisions with people, animals and objects when closing.
• the sensitive edges also called ribs, are electromechanical pressure devices used as a protection against knocks or squashing in many powered systems. These protection devices are used also in powered closing systems.
• This invention refers instead to a protection device specifically designed for sensitive edges for the type of door mentioned and made to avoid the drawbacks complained of in relation to the known technique.
• an electromechanical protection device against knocks or crushing of people, animals or objects by a door in movement according to the preamble in claim 1 , characterised in additionally incorporating a transmitter/receiver circuit set to receive and recognize the signals emitted by the sensitive element and to communicate via radio by a electronic management board associated with the general control centre of the system to be controlled and protected, so as to qualify or stop the control system of the parts in movement according to the signals sent by the protection device.
• the device according to the invention also incorporates an electric feeder for its autonomous supply of electricity.
• the invention therefore represents an important innovation in that it widens the use of the radiofrequency, with a frequency that will be appropriately chosen, between a control centre and at least a peripheral electromechanical protection device, in particular a sensitive edge, in a situation, that is a powered closing system, in which it has never been applied.
• the autonomous feed positioned on board the protection device contributes and eliminates at least the abovementioned expensive and complex work of wiring plus, thanks to the lack of connecting cables, the risks of short circuits.
• an electromechanical protection device or sensitive edge, generically indicated by the number 11 , in combination with a management electronic card 12 and a general control centre 13, for example, of a powered closing system - not shown- having at least a part subject to movements.
• the safety device 11 contains a pressure sensitive mechanism 14, the configuration and function of which are known and, therefore do not need to be described in detail. It is sufficient to point out that this mechanism is preset and projected to detect a contact of the part in movement with another contiguous part and to emit a corresponding block and/or alarm signal.
• the protection device 11 also incorporates a transmitter/receiver circuit 15 in connection with the sensitive mechanism 12 and able to communicate via radio with a management electronic card 12 connected to the general control centre 13. Furthermore, the same safety device 11 is provided autonomously with its own electric feed 16, which can use standard or rechargeable batteries, consequently without connections to an electric network. In the case of chargeable batteries, these can also be preset for their connection to a photovoltaic module (not shown) which, what is more, could also be incorporated in the same device.
• the transmitter/receiver circuit 15 will be preset to receive and recognize the signals coming from the pressure sensitive mechanism 14 of the safety device 11 and to communicate by radio frequency signals with a management electronic card 12, bidirectionaly according to the arrows 17.
• this electronic card 12 will be configured to elaborate the radio frequency signals coming from the transmitter/receiver circuit 15 on board the safety device 11 and to correspondingly manage the general control centre 13.
