Abstract
A safety strip for a striking edge protection device or closing edge protection device has contact elements arranged transversal to the longitudinal extension of the holding bodies, and the points of contact of the contact elements enable a flow of current from one side of one holding body to the other side of the other holding body. To this end, the holding bodies can be provided in the form of contact strips, spring brackets or the like, and sensors can be used instead of the contact elements. These sensors are mounted transversal to the longitudinal extension of the contact strips or of the spring bracket, and the sensors, via the operation thereof, actuate the electrical switching device.
Claims17
A safety strip comprising a switching strip for a striking edge protection device or closing edge protection device with an electrical switching device, wherein the safety strip includes contact elements arranged in holding bodies, wherein the contact elements in a rest position abut each other at contact points under effect of an elastic prestress and, under effect of an outside force on an insulating wedge element arranged between the holding bodies, can be moved apart so that contact is interrupted, wherein the contact elements are arranged in the holding bodies transversely to a longitudinal extension of the safety strip and via the contact points make possible a current flow from one side of one of the holding bodies to a side of the other holding body.
A safety strip comprising a switching strip for a striking edge protection device or closing edge protection device with an electrical switching device, wherein the safety strip includes at least one holding body that carries at least one sensor, that is acted upon by an elastic prestress in a rest state, and that reacts to action of an outer force on insulating wedge elements arranged between holding bodies, wherein
- a) each of the holding bodies is formed as a contact strip or spring bracket,
- b) and at least one sensor is arranged transversely to a longitudinal extension of the safety strip or the spring bracket and actuates the electrical switching device through sensor action.
