An assembling structure for timely and securely locking and releasing a rope includes a housing including two integral side walls for defining a space to allow a rope to pass through; a contact surface on an inner surface of the housing; a pivotal cam including an occlusion section and an engagement surface adapted to pivot about the contact surface from a first position to a second position and vice versa; a torsion spring on one pivot of the cam and having one end fastened in the cam and the other end passing through a limit member of the cam; and a pivotal trigger adapted to pivot about the housing from a third position to a fourth position and vice versa, the trigger including an occlusion member at one end in gear engagement with the occlusion section and a lever at the other end and extending out of the housing.

A number of dolly assemblies are connected in series with chain linkage sections to form an endless conveyor chain for the dolly assemblies to move objects along a track. Each dolly assembly includes a link attachment and a wheel assembly supported by the link attachment. The link attachment includes a base and a body portion. The body portion presents an open-loop partially surrounding an interior and extending between a pair of ends. The ends are spaced from one another to define an opening to the interior therebetween. The pair of ends are also formed in toward the interior to partially surround a respective pocket. Each pocket is configured to receive a portion of an endlink of a respective chain linkage section therein, and each one of the formed ends functions to prevent the endlink of the respective chain linkage section from becoming unhooked from the body portion.

A mooring apparatus (50) comprising a guide portion (55) for guiding a portion of a first mooring line (60), an arrangement (65) for connecting or coupling the apparatus (50) to a second mooring line (70), and a lock (75) or lock means. The guide portion (55) is moveably connected to the arrangement, and the lock is connected to, attached to or provided on the arrangement. A system (250) for tensioning a mooring line, the system comprising the mooring apparatus (50) and the first mooring line (60) and/or the second mooring line (70). A method of tensioning a mooring line, wherein the method comprises providing the system for tensioning a mooring line, and the method further comprises applying a pulling force to a first portion of a first mooring line (60) in a direction away from the apparatus (50).

A block lock for round steel chains, having two half-elements which are displaceable relative to one another for opening and closing the block lock and which each have ends connected to one another via a longitudinal web, of which in each case one end has an insertion plug with a width reduced in relation to the longitudinal web and with retaining webs integrally formed on both sides, wherein at least two parallel retaining webs are arranged above one another on each side, and of which in each case the other end has a receiving pocket which serves to receive the insertion plug and on the two lateral inner flanks of which there are in each case formed at least two retaining grooves above one anotherto form a toothing by receiving the retaining webs. A central web extends inwardly from at least one longitudinal web.

A bicycle-chain outer link plate comprises a first outer-link end portion, a second outer-link end portion, and a first outer-link intermediate portion. The first outer-link end portion comprises a first outer surface, a first inner surface, a first outer-link opening, and a first outer-link end outermost edge. The first outer-link intermediate portion comprises a first intermediate outer surface, a first intermediate inner surface, a first outer-link intermediate outermost edge, a first additional outer-link intermediate outermost edge, and a first intermediate chamfer. The first intermediate chamfer has a first minimum distance defined between the first outer-link intermediate outermost edge and the first inner edge along a reference line. A distance defined between the first outer-link intermediate outermost edge and the first additional outer-link intermediate outermost edge on the reference line is minimum in the first outer-link intermediate portion. The first minimum distance is equal to or larger than 1 mm.

The Invention relates to a Kenter shackle for anchor chains, at least comprising two half elements which can be coupled to one another and a coupling piece element that can be introduced between the half-elements wherein the half elements each have an L-shaped or J-shaped configuration, wherein the external toothing having a plurality of parallel toothing planes is formed at the end of a short connection leg and wherein a receiving chamber is formed at the end of a long connection leg, having an internal toothing with a plurality of parallel toothing planes, into which the external toothing of the short connection leg engages, and wherein the connection legs are connected to one another via a curved clasp. In addition, the receiving chamber in the long leg is extended by means of a cavity above the end side of the external toothing of the short leg and/or above the uppermost toothing plane of the internal toothing pointing towards the clasp.

A release mechanism for separating sections of mooring lines has a main body with two separable first and second halves or sections. A hydraulic assembly within the main body is controlled by an acoustic system, and moves a rod and button so as to move locking shoes within the main body. The locking shoes hold the first and second sections locked together, or alternatively release them to disconnect the mooring line. In addition to the acoustically controlled hydraulic assembly, the release mechanism has a mechanical disconnect, which is operated by pulling the release mechanism into a chain fairlead or the like, or by pulling an encircling member such as a trigger sleeve into the release mechanism. The release mechanism may include instrumentation to transmit various operating conditions of the release mechanism when in use.
