UPRIGHT LADDER
A climbing apparatus comprising a base, an upright member extending vertically upwardly from the base and having first and second sides and first and second carriages slidably locatable along the first and second side of the upright member. The apparatus further comprises a foot support associated with each of the first and second carriages, the carriages being rotatable supported by the carriage; and an upright engaging member extending from each foot support to selectably engage the upright when the foot support is rotated to a first orientation and to disengage from the column when the foot support is rotated to a second orientation.
Folding ladder
Folding ladder (1), in particular for accessing the cavity of a lift shaft comprising: a first side rail (2) and a second side rail (3) that are parallel; a plurality of rungs (10); a stop (15) located on the first side rail (2); a locking member (16) located on the second side rail (3); a locking arm (34) having a first end portion (34a) pivotally attached to the first side rail (2) and a second end portion (34b) that is movable between an unlocking position in which it is magnetically coupled to the stop (15) so that the locking arm (34) abuts the first side rail (2), and a locking position in which it is magnetically coupled to the locking member (16) so that the locking arm (34) is diagonally arranged with respect to both the side rails (2, 3).
SAFETY LADDER
A safety ladder for mounting between a support surface and a ground surface includes two support assemblies and parallel step members pivoted between the support assemblies. Each support assembly includes first and second support rods each having upper and lower ends. The upper ends of the first support rods of the support assemblies are configured to be pivoted to the support surface. The safety ladder is movable between a use position, in which the lower ends of the first and second support rods of the support assemblies are adapted to simultaneously contact the ground surface, and a storage position, in which the first and second support rods stand substantially perpendicular relative to the ground surface. Each of the step members includes a step main body, and rear and front pivot shafts extending into the step main body. Each of the rear and front pivot shafts has an outer circumferential surface.

Ladders and ladder rungs
A ladder and ladder rungs are provided. In one embodiment, a ladder comprises a first assembly having a first pair of spaced apart rails and a plurality of rungs extending between and coupled to the first pair of spaced apart rails. At least one rung of the plurality of rungs may include a first support surface portion, a second support surface portion, and a channel extending between the first support surface portion and the second support surface portion. In one embodiment, a rear surface of each of the first pair of spaced apart rails defines a plane and the first support surface portion is located on a first side of the plane and the second support surface portion is located on a second side of the plane. In one embodiment, at least one other rung is entirely positioned on the first side of the plane.
Scaffold stairway having step holders
A scaffold stairway having two spaced-apart side rails designed as hollow profiles and a plurality of separate steps. The steps can be fastened by their free ends in holding devices for holding the steps that are designed as grooves on the mutually facing lateral faces of the side rails. The free ends of the steps lie on a groove flank or a groove flank portion. As a result, the side rails can be coupled.
LADDERS AND LADDER RUNGS
A ladder and ladder rungs are provided. In one embodiment, a ladder comprises a first assembly having a first pair of spaced apart rails and a plurality of rungs extending between and coupled to the first pair of spaced apart rails. At least one rung of the plurality of rungs may include a first support surface portion, a second support surface portion, and a channel extending between the first support surface portion and the second support surface portion. In one embodiment, a rear surface of each of the first pair of spaced apart rails defines a plane and the first support surface portion is located on a first side of the plane and the second support surface portion is located on a second side of the plane. In one embodiment, at least one other rung is entirely positioned on the first side of the plane.
