Embodiment Construction

[0026]In Figure 1 of the accompanying drawings, a liferaft container 101 is shown. The container comprises a first lower part 102 and a second upper part 103 adapted to fit each other so as to form an enclosure containing the raft. The container is arranged in a support 104 and is secured thereto by an upper strap 105 which extends downwards and is connected to a manual release 106 . The release means is shown as a commonly used slide hook 107 comprising a retaining eye 108 fastened to the upper strap. The slide hook 107 also includes an upwardly extending fork-shaped branch 109 having a protrusion 110 at its distal end and pivotally connected to a stem 111 at its other end (base end). The locking ring 112 is secured around the stem 111 of the slide hook 107 and is movable along the stem. The release device 106 can be locked in place to secure the container 101 by passing the fork branch 109 through an underlying retaining hole 113 of the coupling device.

Abstract

The invention relates to an arrangement (206) for manually releasing nautical life saving equipment, e.g. containers for inflatable life rafts. The release arrangement (206) is located as a connecting link between a first rope arrangement (205) and a second rope arrangement (215) adapted to fixating the life saving equipment. The second rope arrangement (215) forms a loop (213) encircling the first rope arrangement (205). The first rope arrangement (205) is fixed to a connecting stick (207) so that the connecting stick (207) together with the first rope arrangement (205) forms a stop preventing the loop (213) of the second rope arrangement (215) to run along the first rope arrangement (205). The connecting stick (207) is adapted, at release, to turn around an axis formed by the loop (213) of the second rope arrangement (215). The axis is orthogonal to the longitudinal axis of the rope arrangements. The force needed to release the arrangement (206) is rather independent of the tension forces in the rope arrangements (205, 215).

Description

technical field [0001] The invention relates to a device for manually releasing marine lifesaving equipment, such as containers for inflatable lifeboats or rafts. Background technique [0002] All large ships today are equipped with lifeboats or other similar equipment used to rescue the ship in an emergency. These rescue vessels are usually provided with some means for automatically releasing the rescue vessel in an emergency. An automatic release mechanism may be triggered by sensing pressure changes in the environment to release the marine lifesaving device when subjected to a higher pressure such as water pressure at a certain depth. In the case of an inflatable raft, the inflation of the raft is triggered simultaneously with or immediately after the release of the raft. Thus, in the event of a shipwreck, the released raft will be inflated and moved towards the surface of the water to be used as a life raft. [0003] Even if the life-saving appliance is provided with ...
