Abstract: A cantilever stair assembly for installation in segments or sections includes a stair tread module including a stair tread plate having a tread hole. An embedded stair tread is inserted into and fixed within the tread hole. The stair tread module may include a first inner wall stair tread support and a second inner wall stair tread support for mounting to opposite sides of a vertical support member. Each of the first and second inner wall stair tread supports has a first plate with a plurality of support-member-engagement holes therethrough and a second plate perpendicular to the first plate and having a plurality of stair-tread-plate-engagement holes therethrough. The stair tread plate is secured to at least one of the plurality of stair-tread-plate-engagement holes of each of the first and second inner wall stair tread supports.

Abstract: A lightweight tree stand that includes a support platform formed from a molded plastic material. The support platform includes an edge member that defines the perimeter of the support platform and includes a plurality of primary ribs extending between the edge member. The edge members and the primary ribs are integrally molded and each includes an embedded reinforcement rod formed from a continuous fiber material. The continuous fiber material increases the strength without increasing the weight of the support platform. The support platform includes a plurality of secondary ribs that are positioned and configured to define decorative openings within the support platform. The support platform includes one or more tree branch holders that are integrally molded with the edge member and receive artificial tree branches. A frame of the tree stand can include a keyhole that receives a mating key mounted to a tree at a desired location and height.

Abstract: A modular safety unit for application to surfaces requiring reflectivity and friction. The unit has a front surface with a high-reflectivity portion and a roughening agent. The high reflectivity portion and roughening agent can be connate or separate. The unit also has a back surface which may be applied to a platform surface such as a rail car step, ladder rung or walkway. The back surface of the unit comprises an adhesive, or may itself be adhered to a surface.

Abstract: A ladder includes legs (10, 20) and a tread (50). The ladder tread (50) is mounted between two legs (10, 20) and includes a plastic step (52) and a metal support bar (51). The plastic step (52) is supported and connected by the metal support bar (51).

Abstract: An ice ladder has a climbing ladder mounted to an adjustable frame, with the adjustable frame including a securing apparatus mounting on a desired surface, especially an opening in an ice covered body of water. The ice ladder has an adjustable frame or member, a locking bar, and a climbing ladder releasably secured to the locking bar. The adjustable member is secured to the locking bar.

Abstract: A slip resistant step stool includes a step surface with four legs extending downward. A slip resistant surface is bonded to the step surface. The slip resistant surface may be disposed in a pocket and have a ridge surrounding it. The slip resistant surface can be a thermoplastic elastomer. The stool can be manufactured by inserting the slip resistant surface in a mold adapted to form a step stool, then injecting molten resin into the mold, thereby bonding the resin to the slip resistant step stool.

Abstract: An improved tit of a step pad for a step of a step ladder and being of the type having resiliency, a base coincident with a bottom surface of the step pad, a tip, and a pinched waist disposed between the base thereof and the tip thereof and being captured in an associated through bore in the step. The improvement includes the tip of each tit having a dimple extending axially therein to facilitate compression of the tip during insertion into the associated through bore in the step.

Abstract: A scaffold system has at least one supporting structure with a first support member, an opposing, second support member, and at least one cross support rung. The rung has an outer surface comprised of a plurality of gripping sections defined by a plurality of grooves.

Abstract: A high strength polymeric injection molded running board for an automotive vehicle is provided including a longitudinal base portion with an upper first surface and a lower second surface opposite the first surface, the upper surface supporting a foot of a vehicle occupant entering or exiting the vehicle. The running board also includes grip ridges integrally molded with the base portion on the first surface to increase the frictional interface between the first surface and the foot of the vehicle occupant entering or exiting the vehicle. The grip ridges have a crown region and an incline portion connecting the crown region with the first surface. The running board also includes reinforcing ribs for strengthening the base portion, the ribs extend from the base portion second surface and are joined to the second surface generally opposite the incline portion of the grip ridges.

Abstract: A ladder made of composite material comprises a plurality of rungs having an elongated body (19) provided with at least one connecting portion (3) adapted to engage an upright (4) of a ladder. Engagement means (5) locks the rung (2) to the upright (4); this means comprises a coupling element (6) made by co-moulding on the connecting portion (3) of the elongated body (19) or, alternatively, on the connecting seating (20) of the upright (4), a mechanical fastener (9) operatively acting in an installation housing (8) of the coupling element (6) and a locking element (10) adapted to prevent disengagement of the mechanical fastener (9).
