A belaying device for a rope comprises a metal body having at least one slit for passage of a loop of a rope, and a retaining element in the form of a bow integral to the body without being articulated on the latter, and designed to control the relative separation movement of the body with respect to a carabiner passing through the loop. The device further comprises flexible means arranged to move the body towards the carabiner when blocking of the rope takes place, and to move the body away automatically when the rope is released.

A device for controlling movement of a rope comprises a main part and a bar part. The main part defines a central opening, first and second side portions, first and second end portions, at least one projection portion extending from each end portion, and a friction surface formed at junctures of each end portion and the at least one projection portion adjacent thereto. The bar part is movably attached to the first side portion. The bar part is displaced to allow a portion of the rope to be arranged within the central opening and at least partly around the bar part. The bar part is displaced such that the main part and the bar part define first and second opening portions of the central opening and the portion of the rope extends through the first and second opening portions and at least partly around the bar part.

A climbing assistance device having a connection assembly disposed at a predetermined location on the structure, a yoke attachable to a person, a counterweight connected to the yoke by a cable which passes through a pulley system, and a stabilizer operative to stabilize the counterweight to prevent rotation thereof. By employing the stabilizer, the counterweight remains stable during ascent and descent, and the load of the counterweight is controlled.

A rope control device comprising a main part and a bar part. The main part defines a central opening, first and second side portions, first and second end portions, at least one projection portion extending from each end portion, and a friction surface formed at junctures of each end portion and the at least one projection portion adjacent thereto. The bar part is pivotably attached to the first side portion. The bar part may be in a closed position in which the bar part engages the second side portion of the main part. The rope control device may be in an open configuration in which the bar part does not engage the second side portion. When the bar part is in the closed position, the main part and the bar part define first and second opening portions of the central opening.

A mechanical repelling system enables a user to repel down an outside of a building to escape the building. A single cable with a harness is wound through a double array of block and tackle rollers, including a transverse array of moving rollers and an aligned and paired array of fixed rollers. The moving array of rollers attached to a descent speed controlling damper piston with a cable return compression spring.

An apparatus for the controlled lowering to the ground of a cut portion of a tree includes a rope and an anchor having an arrangement of guiding protuberances., each guiding protuberance including a bearing surface frictionally engaging and redirecting the rope without the rope fully encompassing any portion of the anchor including any of the guiding protuberances. Three guiding protuberances define a triangular arrangement. Of the three, a first guiding protuberance is disposed in proximity to an intermediate guiding protuberance defining a segment of a rope path therebetween, and a second guiding protuberance is disposed in proximity tot he intermediate guiding protuberance defining another segment of the rope path therebetween without the segments crossing. A mounting member is attachable to the tree and a guiding member is pivotally connected to the mounting member along a pivot axis and includes an arrangement of guiding protuberances generally extending to each side thereof.

An escape device for allowing a person to escape from a high position to a predetermined landing point. The escape device basically includes: an elastic cord element elastically stretchable to a maximum length substantially at the landing point; a container element provided at the high position; and a carrier element connected with the elastic cord element. Accordingly, a person can descend via the carrier element from the high position and softly land on the landing point. A plurality of carrier elements may be provided and connected together via plural elastic cord elements and auxiliary ropes, using disengagement mechanism, to provide a multistage escape device, so that the carrier elements can be disengaged from one another in sequence when they are falling so as to permit person(s) to descend and softly land on a ground at the landing point.

A fire escape device includes first and second cable drums rotatably mounted on a mounting shaft and spaced apart from each other axially, first and second support cables respectively wound around hub portions of the cable drums, and a coupling mechanism disposed between the cable drums to interconnect releasably the same. The first support cable is unreeled to generate a jerking force to permit rotation of the second cable drum with the first cable drum. Unreeling of the second support cable can rotate the first and second cable drums to reel the first support cable. Thus, alternately lowering people one after another from an elevated floor to a safe location can be achieved.
