摘要:
System for physical mobility activity of a person, comprising at least one fixed support member and at least one contact member to be worn by the person In motion, wherein the support member and the contact member comprise at least one support surface and at least one contact surface, respectively, wherein the support surface and the contact surface constitute the respective components of a hook-and-loop fastening connection consisting of hooks and loops, wherein the hooks have hook stems and hook openings, wherein the hook openings on the support surface or contact surface in question are at least substantially all situated at the same side of the hook stems in question, when considered in a first direction parallel to the support surface or contact surface in question.
摘要:
A descent control device is disclosed manufactured with a bar having holes for guiding a rope used in descent, and a lever designed to pivot or move relative to the bar and compress the opening of one of the holes. Compressing the opening increases friction and slows or stops descent. Control can be from manually moving the lever or by connecting the lever to the descending weight, thereby automatically moving the lever. Hole and pivot geometry may be altered to provide multiple braking options, accommodate varying ropes, and alter normal operating friction.

摘要:
The invention relates to a belay and/or rappelling accessory on a simple or double rope (C). the accessory includes a unitary part that comprises a first opening (2) having a shape permitting the passage of a carabiner, a second opening (3) formed in the central portion of said part above said first opening, said second opening permitting the passage of at least two yarns of a rope (C), and a slot (4) defining a cut-out communicating at its widest upper end with said second opening (3) for passing and blocking in said notch the rope yarn from said second opening. The accessory is characterised in that it further comprises, between the first opening and the lower and most narrow end of said slot (4), a bossing (5) extending transversally on the surface of said single-block part that locally increases the thickness of said part by a value at least equal to the diameter of said rope yarn. The bossing defines a member for returning the rope to the surface of said unitary part, in order to facilitate the manual release of a rope yarn caught in said slot (4).
摘要:
Portable power driven rope climbing apparatus (10) having a motor (14) driving a gear reduction mechanism (18) which drives a pulley wheel (20) securing a rope (12) extending thereabouts a rope output guide member (26) for maintaining the rope in engagement with the pulley wheel an attachment mechanism (42) for attaching an external load. The attachment mechanism (42) comprises a rope entry guide member (22) for supporting a rope as it enters the apparatus, which provides a fulcrum point about which the mass of the apparatus exerts a first moment the attachment mechanism (42) further comprising seat member for supporting said load, said seat member being held remote from the main body (10) such that the load, when mounted thereon exerts a second, opposed moment about the fulcrum.
