Scaffold

Abstract

A scaffold has an upright and a transverse tube connected to it, as well as a handrail tube connected to the transverse tube. The cross-section of the transverse tube is circular with an outer diameter and a flattened portion, which is present at a distance from the outer side of an opposite wall portion. The handrail tube is provided with a C-shaped recess with an inner diameter and a boundary wall which extends over an angle greater than 180 degrees, and of which the ends are at a distance from each other.

1 . A scaffold comprising:
 an upright;   a transverse tube connected to the upright   a handrail tube having one end connected to the transverse tube;   said transverse tube having a non-rotationally symmetrical cross-section;   said handrail tube having a recess near the one end, which recess is such that the handrail tube in a first position with the recess faced to the transverse tube can be moved over the transverse tube in a direction at right angles to the transverse tube, and can be turned about the transverse tube to a second position in which the handrail tube is interlocked with the transverse tube, wherein the cross-section of the transverse tube is substantially circular with an outer diameter D 1  and a flattened part, wherein a middle of the outer side of the flattened part is at a distance d 1  from an outside of an opposite wall part, and in that the recess in the handrail tube is C-shaped and having a circular boundary wall with an inner diameter D 2 , and extending over an angle greater than 180 degrees; and   wherein seen in cross-section, ends of the boundary wall are present at a distance d 2  from each other, and wherein D 2  is greater than or equal to D 1  and d 2  is greater than or equal to d 1  and is smaller than D 1 .
