Abstract: A bi-fold door stop controls movement and travel of lead and pivot doors in a set of vertically hung bi-fold doors. The bi-fold door stop has at least two non-parallel surfaces that each may act upon one or both of the lead and pivot door stiles to limit movement in two directions. Movement transverse to the track longitudinal axis is limited when the bi-fold door is either fully open or fully closed, while parallel movement is controlled by limiting the extent that the bi-fold door may be opened. At least two non-parallel surfaces are provided that each may act upon one or more of the lead and pivot door stiles, while an additional surface may act upon the face of the pivot door. The bi-fold door stop may be fabricated as a single part using common molding operations, and acts directly on the door panels, thereby preserving bi-fold door hardware.

Abstract: A fall protection device includes a frame, a rotation unit, a safety belt, and a braking unit. The rotation unit is rotatably disposed in the frame; the safety belt is wound up on the rotation unit, and adapted to be pulled to drive a rotation of the rotation unit. The braking unit includes a braking plate, a braking block, and a stopper. The braking plate is connected to the rotation unit, rotates with the rotation unit coaxially. The braking block is pivotally connected to the braking plate, and includes a stopping part. The stopping part of the braking block can be spun out by a centrifugal force produced by a rotation of the braking plate, and abuts against the stopper to limit the rotation of the rotation unit. The braking block includes an abutted part. The stopper is disposed in a movement path of the abutted part.

Abstract: A post system for use in fall protection includes a connector to connect to a structure and a support in operative connection with a lifeline to maintain the lifeline at a first height above the structure. When a first threshold force is experienced on the lifeline, the support is operable to lower the lifeline to a second height which is lower than the first height. The ratio of a change in effective length of the lifeline resulting from the lowering of the lifeline to a change in height resulting from lowering of the lifeline (or the ?L/?H ratio) is less than 1. The ratio of the change in effective length of the lifeline resulting from the lowering of the lifeline to the change in height resulting from lowering of the lifeline may also be less than 0.5 or less than 0.4.

Abstract: A scaffold that is quick and easy to assemble while still implementing safety measures. The scaffold can include end caps that resist or prevent users from falling off the ends of the scaffold. The end caps are quickly assembled to the scaffold with a removable rod and pin mechanism. Moreover, to prevent a user from falling off the front or back of the scaffold, a pole and a mid-rail connector can be connected to the scaffold across the front or back, respectively, between an upper barrier and a lower platform. The pole can be inserted through connectors that are coupled to the scaffold, and can also be connected to mid-rail brackets for additional structural stability.

Abstract: A land vehicle assembly is provided with a platform for an operator workspace. A control panel is supported upon the platform in electrical communication with the land vehicle. A caution switch is supported upon the platform in electrical communication with the control panel to provide a signal to the control panel indicative of a caution event. A cable is connected to the caution switch to extend across the control panel. The cable is spaced apart from the control panel so that a predetermined force upon the flexible member actuates the caution switch without significantly obstructing the control panel. A manual force upon the flexible member expands the operator workspace. The control panel is programmed to control a mobile operation of the land vehicle, and discontinue the mobile operation of the land vehicle in response to receipt of the caution event signal.

The deployable supports pivot with respect to the stretcher body from a storage position wherein the first and second supports are generally parallel to the stretcher body and a deployed position wherein the first and second supports are generally perpendicular to the stretcher body. A single lock mechanism locks the first and second deployable supports in the storage position and releases the deployable supports to the deployed position. Either the first or second deployable supports can be arbitrarily pivoted from the deployed to the storage position, with the other deployable support being pivoted from the deployed to the storage position.

Abstract: A foldable quad-chord truss which can be connected end-to-end with like trusses. Each pair of chords are rigidly attached, and connector members intermediate the ends are swivelly attached to the chord pairs to effect the folding into a compact shape for transport and storage. The connector members are adapted for attachment to connector members of beams which may extend perpendicular to a parallel pair of the trusses and attached thereto. The laid trusses and beams is overlaid with sheets of corrugated sheet metal which overlap each other along their adjacent edges. While standing on a sheet of laid sheet metal adjacent ends of an already laid pair of trusses, another truss can be held adjacent the edge of the sheet metal for attaching an end of the other truss along only one side so that it can then be swung outwardly into a position wherein the other end of the other truss can also be attached to rigidly connect the trusses end-to-end.

Abstract: A folding staircase for use in a door opening having a threshold. The folding staircase has a pair of stringers that have an upper end and a lower end that is adapted for contacting a ground surface. The stringers are spanned by at least one tread. A hinge is connected to a floor near the door opening and a threshold plate pivotally connected thereto is movable between a use position and a stowed position. The staircase may be provided with a lifting mechanism that biases the staircase and threshold plate toward their stowed positions. The lifting device provides a variable force that provides more rotational force when the staircase would require a user to bear more of its weight and less force when less of the weight of the staircase would be borne by a user.
