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.

         5 . The access flooring according to  claim 1 , wherein the at least one resiliently deformable element is in the form of an elongate profile-member of a flexibly resilient and/or visco-resilient material. 
     
     
         6 . The access flooring according to  claim 5 , wherein the elongate profile-member has a substantially rectangular cross-section. 
     
     
         7 . The access flooring according to  claim 5 , wherein the elongate profile-member has an at least partially V-like or W-like or zig-zag-like or wave-like cross-section. 
     
     
         8 . The access flooring according to  claim 1 , wherein the at least one resiliently deformable element is connected, on the one hand, to the access flooring and, on the other hand, to the access door. 
     
     
         9 . The access flooring according to  claim 5 , wherein the access door has, along a portion of the edge thereof, a first groove in which the elongate profile-member engages with a first part-region, and in that the access flooring has, along a portion of the edge of the access opening which is opposite the first groove along the portion of the edge of the access door, a second groove in which the elongate profile-member engages with a second part-region, and wherein the elongate profile-member is retained both in the first groove along the portion of the edge of the access door and in the second groove of the access flooring along the portion of the edge of the access opening. 
     
     
         10 . The access flooring according to  claim 9 , wherein the elongate profile-member is secured in the first groove along the portion of the edge of the access door and in the second groove of the access flooring along the portion of the edge of the access opening by rivets and/or by screws and/or by adhesive connections and/or by undercuts. 
     
     
         11 . The access flooring according to any  claim 5 , wherein the elongate profile-member is subjected to material deformation when the access door is opened, and in that one or more cavities are at least partially formed in the region of the material deformation. 
     
     
         12 . The access flooring according to  claim 11 , wherein the at least one cavity is closed at least partially in the direction of the longitudinal sides of the elongate profile-member. 
     
     
         13 . The access flooring according to  claim 11 , wherein the at least one cavity is at least partially formed by an indentation which extends in the longitudinal direction of the elongate profile-member in the surface of a longitudinal side. 
     
     
         14 . The access flooring according to  claim 1 , wherein the region in which the access door is connected to the access flooring has a flexible cover, which covers the at least one resiliently deformable element. 
     
     
         15 . The access flooring according to  claim 14 , wherein the cover produces, during the opening movement of the access door, a force which cooperates with the restoring force of the resiliently deformable element. 
     
     
         16 . A scaffolding access flooring assembly, comprising:
 an access flooring having a top surface;   an access opening disposed in the access flooring, the access opening configured to allow a human to pass therethrough;   an access door moveably connected to the access flooring;   wherein the access door is configured not to pass through the access opening;   wherein the access door is configured to move between an open position and a closed position;   wherein in the closed position the access door substantially closes the access opening with a top surface of the access door being flush with the top surface of the access flooring;   wherein in the open position the access door is moved upwards and allows the human to pass through the access opening;   a resiliently deformable element disposed between and attached to one edge of the access door and to one edge of the access opening, wherein the resiliently deformable element is in the form of an elongate profile-member of a flexibly resilient and/or visco-resilient material; and   wherein the resiliently deformable element becomes deformed when the access door is in the opened position and creates a force which is directed counter to the opening movement of the access door, wherein the force increases abruptly when the access door approaches a near perpendicular position in relation to the access flooring.   
     
     
         17 . A scaffolding floor assembly, comprising:
 a horizontally disposed scaffolding floor defining a top surface, the scaffolding floor having an access opening disposed through the scaffolding floor where the access opening is configured to allow a human to pass therethrough;   an access door moveably connected to the scaffolding floor by a resiliently deformable element, the access door configured to be disposed within the access opening in a closed position and configured to move out of the access opening in an open position; and   wherein the resiliently deformable element becomes deformed when the access door is in the opened position and creates a force which is directed counter to the opening movement of the access door, wherein the force increases abruptly when the access door approaches a near perpendicular position.   
     
     
         18 . The assembly of  claim 17 , wherein the access door is configured not to pass through the access opening. 
     
     
         19 . The assembly of  claim 17 , wherein in the closed position the access door substantially closes the access opening with a top surface of the access door being flush with the top surface of the scaffolding floor. 
     
     
         20 . The assembly of  claim 17 , wherein the resiliently deformable element is disposed between and attached to one edge of the access door and to one edge of the access opening.
