Abstract
A collapsible scaffolding tower having four uprights arranged in two pairs, wherein each of the uprights is formed of three or more telescopically collapsible sections and rigid horizontal bars extend between the sections of the uprights in each pair to form two telescopically collapsible ladder structures, which rest directly on the ground when the tower is in use.
Claims7
A collapsible scaffolding tower comprising:
- four uprights arranged in two pairs, wherein each of the uprights is formed of at least three telescopically collapsible tubular sections;
- and
- at least one rigid horizontal bar extending between each of the pairs of sections of the uprights to form two telescopically collapsible ladder structures that rest directly on the ground when a tower is in use, wherein a support platform is provided having opposite ends each removably resting on a rigid horizontal bar of a respective one of the two ladder structures, wherein the two ladder structures are permanently connected to one another by at least one of a folding and a collapsible structure that allows the two ladder structures to move towards and away from one another while remaining essentially parallel to one another relative to one another at small acute angle so as to form the tower that is narrower.
A collapsible scaffolding tower comprising:
- four uprights arranged in two pairs, each upright including a plurality of telescopically collapsible tubular sections that are collapsible telescopically into one another;
- and
- rungs extending between the uprights of each pair, each rung having opposite ends, one end being connected to a section of one of the two uprights and the other end being connected to a corresponding section of the other of the two uprights of each pair, to form two telescopically collapsible ladder structures that rest directly on the ground when the tower is in use, wherein the two ladder structures are permanently connected to one another by at least one of a folding and a collapsible structure that allows the two ladder structures to move towards and away from one another while remaining essentially parallel to one another.
