Access flooring for a scaffolding

Abstract

An access flooring for a scaffolding has an access door which closes an access opening in the access flooring and which is supported in an opening manner on the access flooring in a state connected to the access flooring. In a region of the access flooring in which the access door is connected to the access flooring, there is arranged at least one resiliently deformable element which becomes deformed when the access door is opened and there is produced by the deformation in the resiliently deformable element a force which is directed counter to the opening movement of the access door and which increases abruptly from a defined opening angle α near a perpendicular position of the access door.

Field of the Invention[0003]The invention relates to an access flooring for a scaffolding having an access door which closes an access opening in the access flooring and which is supported in an opening manner on the access flooring in a state connected to the access flooring.[0004]2. Background of the Invention[0005]On a scaffolding, construction workers and / or craftsmen must often change working level within the scaffolding in order to carry out their work. This may be the case, for example, when they have finished their work at one level and wish to continue this work at an adjacent level. This may also be the case when they have to le...

Benefits of technology

[0018]This object is achieved in that, in a region in which the access door is connected to the access flooring, there is arranged at least one resiliently deformable element which becomes deformed when the access door is opened and there is produced by the deformation in the resiliently deformable element a force (=restoring force) which is directed counter to the opening movement of the access door. The force which is produced in the resilient element and which is directed counter to the opening movement of the access door increases according to the invention (during the opening of the door) abruptly at an opening angle near a perpendicular position of the access door. That is to say, if the access door is orientated almost perpendicularly relative to a horizontal orientation, the (restoring) force which is applied by the resilient element to the access door increases with respect to the horizontal orientation of the access door at or from the opening angle of the access door near the perpendicular position thereof by a multiple, for example, by two-fold, three-fold or by an even higher value, with respect to the value of the restoring force which has been produced up to an opening angle near the perpendicular position of the access door. The force may increase in particular in a stepped manner or in a substantially stepped manner in the region of the opening angle of the access door near the perpendicular position thereof. The characteristic line of the resiliently deformable element has in this case in the region of the opening angle near the perpendicular position of the access door a non-constant extent. An abrupt increase of the force is also present when the force increases from the opening angle of the access door near the perpendicular orientation thereof, with further increasing opening angles of the access door, continuously or exponentially with respect to the value of the restoring force which has been produced up to the opening angle near the perpendicular position of the access door. In the last case mentioned, the resiliently deformable eleme

Problems solved by technology

However, workers may forget to close an access door.

The personal safety on building sites is greatly impaired by such open access doors, which must be avoided.

When the door is completely folded back (opened), complete and automatic closure of the flexible door cannot—not least as a result of the inherent weight of the longitudinal segments thereof—be safely ensured.

As a result of the constructive structure thereof, the fl
