    摘要： A bar unit, formed of longitudinal interconnected strips of spaced angled profiles, leaving a front longitudinal unobstructed slit, and a back slit, broken by cross straps but permitting manual access to the back of the bar unit, has braces, adapted to be secured to concrete form or mold boards attached thereto by brace clamps which contain screw-clamping elements, the clamp elements penetrating through the front slit to provide clamping pressure against the front faces of the profile. The profiles are interconnected, or connectable to further brace clamps, by means of inserted coupling bars, telescopically receivable in the bar unit, and held therein by coupling clamps utilizing counter plates pressing the coupling bars against the profiled faces of the strips of the bar unit, to form a rigid, interconnectable structure, which is longitudinally adjustable and on which the form braces can be placed, as desired, and in accordance with load requirements.

    摘要： A portable observation stand includes a platform and legs pivotal between a raised transport position and a lowered use position. The legs are retained in the use and transport positions by removable braces retentively engaging crossbars on the legs. The stand is transported and erected using a lift vehicle having forks extending beneath the platform, which raises the platform so that the legs fold downwardly by gravity. A blind may be mounted on top of the platform, to include one or more people for various activities, including deer hunting, birdwatching, and wildlife photography.

    摘要： The present disclosure relates systems and methods involving movable/adjustable platforms and/or guardrails. An example system includes a bracket configured to be coupled to a fixed structure having a walking surface. The system also includes a flip door portion rotatably coupled to the bracket and a guardrail portion rotatably coupled to the flip door portion. The system includes a linkage further coupling the flip door portion to the guardrail portion. The system yet further includes an actuator configured to controllably adjust a configuration of the flip door portion, the linkage, and the guardrail portion between an extended configuration and a retracted configuration with respect to the walking surface.

    摘要： The present invention consists of a scaffolding system (1) which is intended for use when working on the roof (2) of a building (3). The scaffolding system (1) is comprised of at least one roof scaffold (4) intended to be positioned relative to the roof with at least one supporting structure (5) comprised of at least one first set of supporting members (11), at least one second set of supporting members (12) and at least one third set of supporting members (13). Unique to the present invention is that the roof scaffold (4) is comprised of elongated parts (9) which run essentially in the roofs direction of slope and crosswise members (10), said roof scaffold (4) positioned at a distance from the roofs (2) surface, which permits objects such as roofing sheet to be moved in the space between the roof scaffold (4) and the roofs (2) surface, and that the scaffolding system (1) includes at least one conveying device (6) by which materials such as roofing sheet (27), other objects and the like may be moved up to the roof (2) and down from the roof on at least one inclined (sloping) plane (20) connected to the roof (2).
