摘要： A telescopically extendable and collapsible ladder assembly includes a top ladder section, a bottom ladder section, and one or more intermediate ladder sections. The assembly may include sliding automatic release actuators, having a slanted actuating surface for interaction with actuator surfaces of spacers provided at each end of a rung of an adjacent ladder section, such that, when a rung is moved towards the rung of an adjacent lower ladder section, the activation surfaces of the spacers push the release actuators into an unlocking position and subsequently position the rung at an anti-finger pinching distance. The top rung of the bottom ladder section may be provided with a centrally arranged grip element that forms a housing for manually operable release actuators provided at the bottom side of the rung.

摘要： A combined step stool and workpiece support device has a folding frame with a rigid front leg structure including front legs and a first support bar interconnecting the front legs at an upper end thereof. The frame also includes a rear leg structure including rear legs, each being pivoted to a front leg via a first hinge for movement of the rear leg structure between a use position and a storage position. Portions of the front legs above the first hinges and the first support bar form a first workpiece support bracket. The device includes a pivotable rigid second workpiece support bracket with a pair of arms, each having a lower end pivotally connected via a second hinge to the frame. The second support bracket is pivotal between a use position and a collapsed position.

摘要： A portable ladder has two stiles interconnected by rungs. The ladder is provided with a stand off device, including two stand off arm assemblies, each being telescopically inserted into a receiving space. Each stand off arm assembly has a base part and a stand off arm interconnected by a hinge that allows the stand off arm to be pivoted between a position in alignment with the base part and an angled stand off position. The stand off arm assemblies are each configured such that—in extended position—the hinge is located outside the receiving space with the base part being located within said receiving space, and also such that—in retracted position—the base part, the hinge, as well as at least a portion of the stand off arm are located within the receiving space.

摘要： A telescopically extendable and collapsible ladder assembly includes multiple collapsible ladder sections provided with an air damper at the bottom end of tubular stile members. The air dampers provide retardation of gravity induced velocity of the collapsible ladder sections upon collapse of the ladder sections. Multiple air dampers include a throttle valve securing device, for cooperating with a throttle valve of the air damper when the collapsible ladder section is in the collapsed position, to secure the throttle valve in its throttle position and/or an obturator device. The obturator device includes a first obturator member and a second obturator member where the first obturator member and the second obturator member are configured to, when the collapsible ladder section is in the collapsed position, in combination provide additional throttling.
