Definitions

  • the present invention relates to a release mechanism for releasing maritime rescue equipment, preferrably being openable containers comprising inflatable lifeboats.
  • Such containers are, while being fastened to suitable support stands on board the relevant ships, by means of claspable straps releasably retained on the support stands while having one of the ends of the straps permanently fastened onto the support stands and having the other ends of the straps releasably fastened to the support stands in a generally standardized manner involving a so-called release hook being hooked into a hole within the support stand.
  • the release hook comprises an eye portion adapted to stay in connection with a back-bend end of the straps and a protruding base portion of the hook with a free end portion extending relatively far backwards which at the end comprises a retaining protrusion for the retaining of an anchoring ring encirculating the base portion of the hook and the respective free end portion.
  • the free hook end portion can be let through the retaining hole within the support stand og thereafter be locked against pull-out by letting the locking ring down over the retaining protusion on the free end of the hook.
  • the backwards protruding free end is resiliently depressible into the base portion of the hook so that, to manually achieve a release of the connection provided by the hook, the hook can be sufficiently compressed to provide a releasing of the locking ring from the retaining protrusion and thereafter flip and retract the hook from its grip in the hole in the support stand thus releasing the floatable container whereby a connection to the ship still is in general maintained by means of a lifeline which at last may be cut by means of release means or a knife having been installed in the liferaft.
  • the hydrostatic release device is so that the two main members which may be mutually locked or released are mounted respectively through a fixed connection to the support stand and in shape of a releasable member being provided with the hole which receives the aforementioned release hook whereby it is mandatory that long time before an activation of the hydrostatic release device, as caused by a factual sinking of the ship, may take place, it is possible manually to provide a release.
  • the hydrostatic release device thus provides an added safety without deviation from the safety provided by means of the aforementioned, in general employed release hooks.
  • the release hook has to be released from the retaining gripping by being bent outwards to achieve a transverse translation of the external hook portion away from the retaining hole, and this necessary bending outwards of the hook is made difficult to perform due to an increased pulling within the eye-end of the hook. Therefore, by means of the present invention a changed standard for the fastening of the releasable strap end has to be provided for so that a fairly easy provided releasing is safeguarded independent on the size of the tension within the strap.
  • a further purpose according to the invention moreover is to depict an embodiment of the hydrostativ release device enabling it to function as a the manual release means.
  • the coupling portion of the hydrostatic release device being adapted to be coupled onto the strap through the aforementioned release hook is bracelike shaped in such a manner as to make it directly or releasably couplable to the eyelet or to the loop of the strap while employing a releasable coupling beam which by means of a transverse locking-split-pin or a corresponding manually pull-out locking means is locked against any unintended release from the bracelike portion.
  • the aforementioned coupling portion of the hydrostatic release device may function as well as an automatically releasable portion or as a strap retaining means making a manual releasing of the strap possible.
  • a locking-split-pin which is provided with a rigid strap ring will in practice easily lend itself to be manually pulled-out even in case of a strong-tensioned coupling connection, thus a releasing will more easily be brought to take place than while employing the aforementioned release hooks.
  • Hydrostatic release devices may be activated in different manners than by employing water pressure, different manners to be mentioned are thus: By means of water contact, by means of electric signals, by means of radio signals, by means of air-/gas pressure, by means of vacuum, but also other manners of releasing are possible as well as combinations hereof all dependent upon the various conditions.
  • a liferaft container 2 which is arranged supported in a support stand 4 and is fastened to the support stand by means of an upper strap 6 which connectingly extends down to a retaining eye 8 of a release hook 10 which comprises an upwards extending fork branch 12 which is let through a below arranged retaining hole comprised in a part 14 of a coupling.
  • This part in itself forms a releasable part of a hydrostatic release coupling device 16 which moreover is coupled onto a fixed bottom part of the support stand 4.
  • the strap 6 thus lends itself to be released as well manually by being taken off the release hook 10 and away from the element 14 as automatically through a releasing of the element 14 itself.
  • the upper end of the part 14 of the coupling is shaped as a bracelike member 18 of which one branch comprises an outwards extending protrusion 20 while the other branch exhibits a hole for receiving a locking split-pin 22.
  • transverse beam 24 which at the ends comprises eyelets, adapted to be put down over the ends of the branches, and between them a straight beam portion so that the transverse beam 24 is adapted to be able to be inserted through an eyeshaped free end of the strap or through the loop of the strap 6 and thereupon can be mounted in place on the branch ends of the bracelike member 18 with inclusion of the accompanying locking provided in part through the providable gripping connection with the locking protrusion 20 and in part through the mounting-in-place of the locking split-pin 22.
  • the part 14 of the coupling will function as being automatically releasable just as formerly provided, but the strap 6 itself is now manually directly releasable away from the part 14 of the coupling, i.e. performed by a simple pulling-out of the locking split-pin 22 through the employing of a pull-eyelet 26 provided on it.
  • the illustrated embodied device according to the invention furthermore presents the advantage that due to the achieved simplified embodiment the risk for an erroneous mounting of the unit might take place is minimized, because the embodiment in itself guides how the single relevant items belonging to the coupling system have to be connected together. This feature forms an important aspect with regard to safety.
