Abstract: A mobile containment platform method and system for sandblasting and the like used in bridge reconditioning and painting that requires removal of paint from the support structure of the bridge. The containment platform provides a safe secure entrapment envelop for spent abrasive and removed paint residue.

Abstract: A safety net is raised during construction of a multi-floor building without the use of tracks vertically attached to the outer building face. A pair of support structures hold the net in a fully deployed condition adjacent the outer building face. Each support structure is held in place by a plurality of holders. A positive locking device is provided on each holder and support structure.

Abstract: A birth safety net to prevent the dropping or falling of a new born child as it exits the birth canal comprising a fabric body, five sides, five corners and means for securring each corner to a portion of the birthing chair or birthing bed.

Abstract: A debris barrier for a high rise construction structure comprises a woven flexible mesh netting. A cord longitudinally extends along the top of the netting to form a reinforced border. The top of the netting is clipped to a safety cable so as to vertically suspend a portion of the netting. An anchoring strip is fastened to the netting. The netting is anchored to the floor slab by driving fasteners through the anchoring strip.

Abstract: A device for horizontally moving an apparatus such as a gondola working at a high location such as a wall surface of a building comprises a mounting frame fixedly provided on the upper end portion of a structure and having a vertically extending rotary shaft receiving portion, a rail supporting member having a rotary shaft received in the rotary shaft receiving portion and also having an arm extending substantially normally from the rotary shaft and including a rail supporting portion at the foremost end thereof, a horizontally extending rail disposed detachably on the rail supporting portion, a rail pivoting device associated with the rail supporting portion and the rail for pivoting the rail when the rotation shaft is rotated, and a trolley mounted on the rail for suspending the apparatus working at a high location. The rail can be provided only provisionally when required and not permanently fixed to the structure.

Abstract: A guard system for a scaffolding arrangement having upper and lower platforms traversing a pair of spaced apart poles. The platforms respectively project from opposing directions of a plane defined by the poles. The guard system includes a net wall which spans the gap between the upper and lower platforms. A clamping arrangement clamps the upper edge of the net wall to the upper platform and a lower edge of the net wall to the lower platform.

Abstract: A scaffolding system for performing a work such as repair, coating or tiling on an outer wall surface of a building, chimney, petroleum tank or the like comprises parapet wall hooks provided on the top portion of a building, hanging stages suspended from the parapet wall hooks by means of first cables and arranged in horizontal alignment with one another, protective nets which can be stretched between the parapet wall hooks and the hanging stages, and means for lifting and lowering the protective nets by means of second cables secured to the protective nets. The protective nets can be lifted or lowered as desired regardless of position of the hanging stages and without lifting or lowering the hanging stages. The protective nets can be readily lowered and stored in the hanging stages when a strong wind is expected whereby damage to the protective nets due to wind can be prevented.

Abstract: A safety system for a multi-story building under construction includes parallel, vertical stationary guide channels or tracks secured to the side of the building. Vertically moveable slide rails are slidably mounted within the guide channels. Cantilever struts extend diagonally upwardly and outwardly from connections with the slide rails. A safety net extends along the building with its outer edge anchored at the outer ends of the struts and with its inner edge anchored on the moveable slide rails. Vertical chains or cables are connected between the slide rails and a construction crane at the top of the building to lift the slide rails and net while in an extended condition to a new working position. Brakes acting between the slide rails and guide channels automatically release to enable upward movement and automatically lock to hold the net in the new working position.

Abstract: A net for use as an embarkation-debarkation net having spacer blocks provided integrally therewith for maintaining the plane of the net configuration spaced forwardly of a rear portion of the respective distributed spacer blocks. Securing elements are provided at less than all of the crossing positions of the longitudinal and transverse lines of the net. An improved spreader structure is provided utilizing a tubular cross member and short tubular vertical members for receiving the longitudinal lines of the net. The spacer blocks provide a self-fending action when the net is used as an embarkation-debarkation net, and provide cushioning of cargo where the net is used as a cargo net.

Abstract: A net is mounted to hang freely from the end of a pair of pivotally secured arms extending from the underside of a helicopter. The arms and net hang down in a vertical position when the helicopter is in flight and a motorized lifting mechanism raises the arms and net into a forward horizontal position for particular rescue missions or on land. A movable weight is guided along a tube extending adjacent the rear of the helicopter to balance the weight of the arms and net. A resilient bumper is mounted on the front of the net and a locking mechanism secures the arms in the horizontal position. The lifting mechanism is mounted close to the center of gravity of the helicopter to avoid balance problems.

Abstract: An adjustable scaffolding system adaptable to the progressive growth of a building during construction has a series of spaced uprights, each having a plurality of vertically disposed slots for the sliding engagement of the edges of a plurality of frames. The frames and a third slot on the uprights engage fastening means protruding beyond the edge of a floor slab of the building.

Abstract: A Y-shaped support structure is movably attached at its two arms to a track vertically attached adjacent the face of a building. Two of the arms of the Y-shaped support structure are movably engaged in a slot in the track and a net is suspended between the support structure and a similar support structure on a parallel track. The support structures with attached net can be raised by removing the supports from the upper arms of the Ys and sliding the ends of the upper arm upward while folding the net toward the building, then supporting the upper arms while the lower arms are raised while simultaneously unfolding the support structure outward, and finally supporting the bottom arms of the Ys. The support structure is lowered by reversing the procedure for raising it.

Abstract: An emergency escape structure is provided for use on the exteriors of high buildings having outwardly projecting vertically spaced balcony structures. The escape structure includes a vertically extendable upright mounting structure for vertical expansion between, tight frictional engagement with and anchoring between the upper and under surfaces of adjacent vertically spaced lower and upper balcony structures. A horizontal support frame is supported from and projects outwardly of the mounting structure intermediate the upper and lower ends thereof and the support frame includes a generally horizontally disposed flexible catch structure supported therefrom at points spaced about the periphery of the catch structure. Further, the escape structure may have its mounting portion mounted within a room of a building adjacent the outer wall of that room and with the net portion of the escape structure projected through a window opening in the outer wall.

Abstract: For use in conjunction with building construction, a safety net intended to be supported outwardly of the edges of the floors of the building, comprising a net fabric supported at its inner end by a bracket secured to the upper of two adjacent floors, and secured at its outer end to the top of an extension pole the bottom of which is supported in an adjustable pole bracket secured to the lower of the two adjacent floors.
