Abstract

A stepladder having front stiles with steps extending therebetween, rear stiles connected to the front stiles in a hinged manner, a connecting member extending between the top ends of the front stiles, and a U-shaped bracket, extending from the connecting member which can swivel and/or slide and which spans a plane extending transversely to the stepladder in the usage position. Connecting member has a through-hole, said through-hole enabling a connection to the cavity of the front stiles, each through-hole is penetrated by a respective side limb of the bracket, in a first position of the bracket the side limbs extend within the cavities and the cross limb be accommodated by the connecting member, and in a second position of the bracket, said bracket extends on the plane extending transversely to the stepladder and the side limbs extend outside the cavities and are supported at the ends on the connecting member.

Dependent claims

A stepladder (10) including a first cross-beam or riser beam (12, 14) with rungs (20, 22) running between them, hinged with a second cross-beam or support beam (16, 18) connecting the first cross-beam, a connection or shell element (34), which is connected to it at the upper ends (30, 32) of the first cross-beam, as well as a U-shaped hanger (72, 172) exhibiting the hanger side-legs (68, 70) and a hanger cross-leg (74,174) and emerge pivotably or movably from the connection or shell element, in which in a use position of the hanger, it extends a plane running transverse to the stepladder,

characterized in that,
the connection or shell element (34) in the area of every first cross-beam (12, 14) exhibits a perforation (64, 66) making a connection possible to the space of the first cross-beam, that each perforation is penetrated by one of the hanger side-legs (68, 70) respectively, that in a first position of the hanger the hanger side-leg extends inside the space of the first cross-beam and the cross-leg (74, 174) is received by the connection or shell element (34) or runs in this area, and that in a second position of the hanger it runs in the plane extending transverse to the stepladder (10), the hanger side-legs run outside the space of the first cross-beam and are supported at the ends on the connection or shell element (34), whereby at least one of the hanger side-legs in its free end area (76) exhibits its true cross-section, which is greater than the true cross-section of the perforation.
