Abstract: An apparatus and an associated method relates to a directionally polarized deceleration module (PDM) include a shuttle (125) fixedly coupled to a spring-biased spool (120) rotatable coupled to a module housing (115), a dynamic braking member (DBM) (130) and the shuttle (125) configured to travel inside a channel anchored to the module housing (115). A tether may be anchored on a proximal end to the spool (120). As the tether is retracted, the DBM (130) may be pushed by an angled distal-end of the shuttle (125). The DBM (130) may be forced between the angled distal-end of the shuttle (125) and an inner channel wall, providing motional resistance to the tether. As the tether is extracted, the DBM (130) may be pushed substantially normal to a proximal-end of the shuttle (125), providing minimal motional resistance to the tether. Various PDMs may decelerate safety lanyards in one direction to substantially avoid tangling and/or damage.

Abstract: Various embodiments illustrated herein disclose a full body harness that includes a connector. The connector includes a first plate and a second plate, where the first plate is identical to the second plate. The first plate and the second plate includes a plurality of slits to facilitate passage of a first harness and a second harness there through. The first plate is rotatably coupled to the second plate such that they are rotatable with respect to each other. Such a connector automatically enables easy adjustment of the harness based on an activity of a user who is wearing the harness.

Abstract: A shelf and ladder combination includes two support rod units, partition plates connected between the support rod units, a cross bar, two main connecting brackets connecting the cross bar to the support rod units, and a ladder unit. The ladder unit includes two ladder legs, at least one fixing unit, and a plurality of rungs connected between the ladder legs. Each ladder leg has a first end portion adjacent to the crossbar, and a second end portion opposite to the first end portion. The at least one fixing unit is sleeved on the crossbar, is slidable along the crossbar, and is connected to the first end portion of one of the ladder legs.

Abstract: A wall-mountable perch includes: a frame including: first horizontal side members; a first cross member connected to each of the first horizontal side members proximate to a respective distal end of each of the first horizontal side members; second horizontal side members connected to the first horizontal side members; a platform connected to the second horizontal side members; a plurality of support arms each having a proximal end connected proximate to a proximal end of the frame, each support arm extending vertically upward from the frame and being configured to be flexible to bend along a respective length of each of the plurality of support arms; tension arms each connected to a respective horizontal side member; and adjusting means for producing tension in the tension arms and for causing a second cross member of the wall-mountable perch to move closer to the platform.

Abstract: A scaffolding assembly adapted to be releasably attached to an elongate support member such as an overhead pipe. The scaffolding assembly has a split collar and a platform assembly adapted to be releasably attached to the split collar. The split collar comprises at least two segments which can encircle the pipe and be secured to one another. The platform assembly which includes a platform deck has a connector formation which extends laterally outwardly from the deck to an extent that it can engage a receiving formation on the collar assembly and thereby attach the platform assembly to the collar assembly.

Abstract: An assembled ladder includes two supporting leg assemblies, at least one rung and a bridging part, wherein each supporting leg assembly of the two supporting leg assemblies includes a front supporting leg and a rear supporting leg rotatably connected to the front supporting leg, and the at least one rung and the bridging part are detachably connected between the two supporting leg assemblies. During logistics transportation, the at least one rung is detached from the two supporting leg assemblies, the bridging part is also detached from the two supporting leg assemblies, and the two supporting leg assemblies are stacked. In use, two ends of the bridging part are fixedly connected to the two supporting leg assemblies, and two ends of the at least one rung are also fixedly connected to the two supporting leg assemblies.

Abstract: A rotating retractable step system positioned within a cutout of a wall is presented. The rotating retractable step system comprises a foot pedal and a support shaft. The foot pedal is configured to be stowed in a vertical orientation within the cutout of the wall, and to rotate between the vertical orientation and a horizontal orientation. The support shaft is associated with the foot pedal, such that movement of the support shaft extends the foot pedal outwardly away from the cutout, or retracts the foot pedal towards the cutout.

Abstract: Methods and apparatuses related to harnesses are provided. An example harness may include: a first leg strap comprising a first elongated member, a lower strap comprising a second elongated member, and an upper strap comprising a third elongated member.
