摘要： A modular fall protection system has an adjustable frame that can be mounted onto an external structure and used to support the weight of a user who has fallen. The adjustable frame has a length-adjustable mast, set of connective braces, and an anchor point. The length-adjustable mast is a telescoping post that can be extended or collapsed to provide fall protection to the user at various heights. The connective braces extend between the length-adjustable mast and the external structure and are used to maintain the length-adjustable mast in an orientation that facilitates suspending the user in the air after a fall. The anchor point enables the user to be tethered to the length-adjustable post. Preferably, the system has a detachable walkway and handrail that can be mounted onto the adjustable frame and provide fall protection in a variety of situations.

摘要： A brace tool comprises a rigid frame, a platform mounted on the frame for adjustable positioning of the platform relative to the frame, and a plurality of suction cups. The plurality of suction cups can be removably attached to a flat surface that is adjacent to an inclined surface 12 above which work is to be performed. The platform can be adjustably positioned relative to the frame 22, and then secured in its adjusted position. The platform can then be used as a brace that can be engaged by the person on the inclined surface that is performing the overhead work and prevent the person from sliding down the inclined surface.

摘要： A multi-directional scaffold transport device, which may be attached to each base of a scaffold's legs, provides increased mobility in relation to movement atop corrugated floor decking with vertical anchor studs used in conventional steel I-beam superstructures. The device comprises an elongated flat plate with angled extensions. The angled extensions may form a trapezoidal shape, or more preferably a triangular shape, and may be curved or have compound curvature to enable deflection of the device to either side of any anchor stud encountered, rather than jamming thereon. The elongated flat plate may have minimal length sufficient to normally receive support from at least two peaks of the corrugated decking. The device may incorporate threaded studs protruding from the elongated flat plate, which may be received by holes in the base of the scaffold, and be removeably fastened thereto using nuts. The device may also incorporate vertical walls for increased stiffness.

摘要： Ladder safety devices including a gutter guard, a ladder extender, a ground spike and a ladder shoe, are described that improve the stability of a ladder placed against a structure with or without guttering. Embodiments of the gutter guard prevent the ladder from contacting the gutter, distribute the ladder's weight to minimize structural damage, avoid ladder-gutter contact resulting in and help to hold the ladder in place. The ladder extender offsets the ladder from the shingles of a roof when gutters are not present. The ground spike and ladder shoe stabilize a ladder placed on a soft or hard surfaces, respectfully.

摘要： An adjustable and transportable scaffolding (10) is described. It comprises an adjustable leg support mechanism (20) for a scaffolding having vertical corner frame members (11) connected to horizontal frame members (12) and cross-braces (13). The mechanism (20) comprises an open-ended sleeve (21) adapted to receive a support rod (22) therethrough and wherein the support rod has at least a horizontal toothed edge section (23) adapted to secure to a bottom support foot (24). A tooth engaging member (25) is pivotally secured to the sleeve (21) and has a tooth engaging head (26) biased against the toothed edge (23) inside the sleeve (21) for supporting the sleeve about the support rod (22) while permitting upward displacement of the sleeve about the rod. The tooth engaging member (25) can be unbiased from the toothed edge (23) of the support rod (22) to permit downward displacement of the sleeve (21) about the rod (22). A locking member (40) is provided to lock the tooth engaging member (25) in arresting position with the toothed edge (23). The sleeve (21) is also provided with a connector (52) for support engagement with one of the corner frame members (1) of the scaffolding (10).

摘要： A sleeve is disclosed for a leg of a ladder. The sleeve includes a length of generally “U”-shaped cross-sectional material, and the sleeve slides over an end of the leg of the ladder. Each rung of the ladder slides along an open portion of the generally “U”-shaped cross-section as the sleeve is slid over and along the leg of the ladder. When the ladder rests against an object, the sleeve can be longitudinally adjusted along the leg to reduce marring the object from contact by the leg of the ladder.

摘要： A support member for roof scaffolding having a base plate that is designed to be secured to a roof deck. The base plate is operably connected to a hinged plate that carries on it a sleeve that is used to engage scaffolding. Because of the way the hinged plate is mounted onto the base plate, a wedged end plate is formed to allow the base plate to easily slip underneath a shingle on a roof. Furthermore, because of the hinged plate the scaffolding is able to be maintained at a right angle to the ground.

摘要： A ladder system comprises first and second rails with at least one rung connected between and perpendicular to both rails. First and second non-linear rail slots are located adjacent the bottom of the respective rails. Also, the ladder system comprises first and second ladder shoes. First and second bolts extend through the first and second shoes, respectively, and the first and second slots, respectively, to moveably connect the first and second shoes to the first and second rails, respectively, with both slots of a shape so that each shoe can move about the bottom of each respective rail and each respective rail can rotate relative to each respective shoe inside each respective shoe without interference occurring between the rails and shoes. A method of climbing comprises placing the feet of ladder shoes attached to rails of a ladder system in a flat position on the ground at a first level with the rails vertically oriented relative to the ground and essentially the full weight of the ladder system on the ladder shoes. The rails are then rotated relative to the ladder shoes via a curved slot in the rails at least 15.degree. while essentially the full weight of the ladder system is on the ladder shoes which are maintained essentially still on the ground.

摘要： A load-dispersing device for use with a ladder has a pail of flexible members having first and second configurations and a memory to return the members from the second to the first configuration. An interior cavity within each member is exposed, when each member is in the second configuration, through a longitudinal slit. Separating the longitudinal slit exposes the interior cavity placing the member in the second configuration for mounting on the respective ladder side rail and releasing the longitudinal slit returns the member to the first configuration and secures the member around the respective side rail. The member having contact and locking areas which can be manufactured either from separate material or integral with one another. The contact area can have an undulating surface and can have a spring embedded within the contact area to return the member to the first configuration. The contact area can alternatively be adhered directly to the load-bearing surface of the ladder.
