• the spring means 14 shown in FIGS. 3a and 3b are tension springs. In the open state of the edge protection device, the spring means 14 are in a compressed and defined, pre-stressed state. If the edge protection device is now compressed, the outer pivot bearings 8 are removed from the inner pivot bearings 9, as described, and as a result there is an upward movement of the second connecting element 10 ′′ and a downward movement of the first connecting element 10 ′ the tension spring 14. If the pressure on the edge protection device now loses, the spring 14 contracts and the connecting elements 10 'and 10 "are returned to their starting position, which is equivalent to a return movement of the edge protection device or the edge protection strip 3 to their starting position .
• the compression springs 14 can also from the outer or the inner
• Swivel bearings 8, 9 run to the edge 2 or to the edge protection strip 3.
• the spring action or the direction of the spring action of the spring means runs in an axis parallel to the edge protection strip 3 or at an angle to the edge protection strip 3, which decreases when the edge protection strip 3 moves in the direction of the edge 2.
• the counterforce becomes weaker the more the edge protection device is compressed, with a disproportionately large drop in the counterforce when the end position is reached in the fully compressed state.
• the force decreases with the cotangent of half the angle ⁇ .
• edge protection strip 3 When the edge protection strip 3 strikes an obstacle, a force of approximately 25 to 200 N, but at most 1400 N, is initially exerted on the obstacle due to the pretensioning of the spring means. This force is measured by a detection device, which causes the edge 2 or the sliding door to be stopped or reversed. This takes place with a certain time delay, which also results in a certain overtravel of the dangerous edges 2. The edge protection strip 3 or the edge protection device now grant this certain Overrun without endangering safety. Due to the interaction of the spring action in the described direction and the action of the forces perpendicular to it via the scissors, a strong degression of the force which the pressed edge protection strip 3 exerts on the obstacle is achieved at the end of the movement, ie when the edge protection device is strongly compressed.
• This also has the advantage that, in the case of a door that is closed and in which the edge protection device is compressed, the residual force of the edge protection device is not sufficient to push the door open.
