  • Patent number: 10258829
    Abstract: A rope-climbing device has an upper assembly with planar side plates spaced apart by a roller, such that the side plates rotate relative to one another about a roller axis, a spine unit comprising planar links of common width each of half the plate spacing, the links pivoted at a central point, and a lower assembly comprising third and fourth side plates spaced apart by a clamp element such that the third and fourth side plates are enabled to rotate relative to one another about the clamp axis, and the clamp element is enabled to clamp a rope between the plates. The device may be opened by aligning pivot points, a rope inserted, and closed on the rope. Engaged on the rope, the device may be set to slide on the rope, or clamp to the rope by action of a user.

  • Patent number: 10240392
    Abstract: A vertically orientated ladder apparatus allowing a climber to adopt an improved climbing stance wherein the climber's arms are poised economically in front of the climber within the climbing passage; the climber's legs are spread for the lateral stability of the climber so as to reduce the tendency of the climber falling sideways; and the climber is substantially upright such that the climber's center of gravity lies substantially between the opposing steps (11) so as to allow the climber to release the climber's grip on the hand rails (14) while remaining balanced and supported by the legs of the climber. Opposing steps (11) are level or staggered. Embodiments include three or four stiles (12, 15).

  • Patent number: 10240395
    Abstract: Ladder modules are provided in manageable length sections. The first section is secured at the top with a multi-hole horizontal mounting bar that is secured by a ratchet strap with hooks. The bottom of the first section rests firmly on the ground with a cleat at the bottom to secure the ladder section and prevent shifting. The second section contains a ball on the bottom of the structure that is mounted onto the first section by placing the ball into the receiving end of the first section, which allows the second section to pivot 360 degrees and lean and tilt fore and aft. This section is also secured to the tree with a ratchet strap and hooks, and is safe to climb to the next section after tightening the ratchet strap. Additional sections can be added in the same manner as the second section to pivot and level as needed.

  • Patent number: 10240394
    Abstract: A slip-resistant support base and method of making and using such a support base. A slip-resistant support base may include a resilient pad having an exposed lower expanse opposite an upper pad surface, the lower expanse being characterized by a two-dimensional distribution of downwardly open concave recesses having rims forming a lower extremity of the support base. The lower expanse may be made by shearing off a layer of a first major face of a pad of resilient closed cell foam to expose an expanse of cut cells. In some examples, the support base includes a body and the resilient pad as a resilient substrate. The body is preferably configured to support an external object positioned on a body upper surface. The resilient substrate is preferably attached to and extends along at least a portion of a body lower surface. The resilient substrate lower expanse is opposite the body lower surface.

  • Patent number: 10227799
    Abstract: A hinged hatch in a gas containment cover particularly for a sewage treatment tank has a slide bolt contained within a shaped channel of an extrusion of the hatch, positioned to engage the bolt at a mid-level position of the adjacent fixed beam or other member of the tank cover. The position of the bolt enables the hinged hatch to fully seal against a rubber-covered lip of the adjacent structural member, so that the bolt latch does not compromise integrity of the gas seal. As the bolt is slid into locking position it forces the hatch cover down more tightly against the gas seal.
