Scaffolding frame

Abstract

A scaffolding frame comprising two parallel posts which are connected by two traverses arranged perpendicularly with respect to the posts. The lower traverse is removably suspended on suspension knobs on the posts. The suspension knobs have a connection which is essentially T-shaped in cross section, whereby the lower traverse has angled brackets at its ends, each of which has a recess therein, which in the upper region is the same as or insignificantly wider than the shank of the T-shaped connection, and in the lower region is the same as or insignificantly wider than the head of the T-shaped connection. The connections extend in the mounted state of the traverse through the recesses. The brackets each have on the outwardly facing surface above the recesses a flange which rests on the upper side of the free end of the suspension knob.

What is claimed is:  
     
         1 . A scaffolding frame comprising two parallel posts which are connected by two traverses arranged perpendicularly with respect to the posts, whereby the lower traverse is suspended on suspension knobs of the posts and is thus removable, wherein the free end of the suspension knobs each have a connection which is essentially T-shaped in cross section, the lower traverse having angled brackets at its ends, said brackets each having a recess therein, which in the upper region is the same as or insignificantly wider than the shank of the T-shaped connection, and in the lower region is the same as or insignificantly wider than the head of the T-shaped connection, the connections extending in the mounted state of the traverse through the recesses, and the brackets each having on the outwardly facing surface above the recess a flange which rests on the upper side of the free end of the suspension knob.  
     
     
         2 . The scaffolding frame according to    claim 1   , wherein a screw is provided as the T-shaped connection, wherein the face of the free end of the suspension knobs has a thread, and wherein the screw is screwed into this thread.  
     
     
         3 . The scaffolding frame according to    claim 1   , wherein each bracket is tapered at its free end.  
     
     
         4 . The scaffolding frame according to    claim 1   , wherein each bracket has an S-shape.  
     
     
         5 . The scaffolding frame according to    claim 1   , wherein the free end of the suspension knobs has a flange on the upper side, on which flange rests the flange of the bracket.  
     
     
         6 . The scaffolding frame according to    claim 1   , wherein the flange of the brackets is bent downwardly at an angle and grips behind the flange on the upper side of the suspension knobs.  
     
     
         7 . The scaffolding frame according to    claim 1   , wherein two second suspension knobs are mounted on the posts of the scaffolding frame, and wherein the first mentioned and the second suspension knobs have mostly the same outer cross-sectional profile which extends from the fastening point of the suspension knobs on the posts to the free end of the suspension knobs.  
     
     
         8 . The scaffolding frame according to    claim 7   , wherein each suspension knob is a U-shaped bent part which has a continuous and essentially rectangular center part as a web on which are mounted symmetrically two essentially rectangular side parts as legs which are each bent at approximately 90° with respect to the center part, and wherein the bent part is welded with one of its faces to the post.  
     
     
         9 . The scaffolding frame according to    claim 8   , wherein the side parts project at the free face the center part, wherein projecting end pieces are bent inwardly at 90° and close off the face, wherein a semicircular recess is provided at the free end edges of the side parts, wherein both recesses form an essentially circular opening in the face, and wherein a nut is mounted on the inside of the opening, which nut forms the thread for the screw provided as the T-shaped connection.  
     
     
         10 . The scaffolding frame according to    claim 8   , wherein the side parts are disengaged in the area of the bent edge.  
     
     
         11 . The scaffolding frame according to    claim 8   , wherein the side parts are bent at their lower ends and lie approximately at 90° with respect to one another.  
     
     
         12 . The scaffolding frame according to    claim 1   , wherein each bracket is bent at least in the upper area at approximately 90° toward the end of the traverse.  
     
     
         13 . The scaffolding frame according to    claim 1   , wherein the inside spacing between the bent section of the bracket is equal to or slightly larger than the width of the knob.  
     
     
         14 . The scaffolding frame according to    claim 13   , wherein the inside spacing between the lateral bent sections increases toward the traverse.
