Definitions

  • the invention relates to an outrigger for mooring of boats, comprising a boom attachable essentially perpendicularly to a jetty, quay or the like, the end of the boom facing the jetty or the like having at least one cross-stay extending at an angle to the boom and attachable to the jetty etc.
  • the object of the present invention is to eliminate these disadvantages.
  • the invention thus consists of an outrigger comprising a boom attachable essentially perpendicularly to a jetty, quay or the like, the end of the boom facing the jetty or the like having at least one elongated bracing member, or cross-stay, extending at an angle to the boom and attachable to the jetty or the like.
  • the invention is chiefly characterized in that the cross-stay is detachably fitted to the boom by means of a fastening member which is shaped to fit snuggly around half or less of the boom, whereby a unity member is obtained, and to mate with the boom by means of a fixing device which, through the action of a locking device which presses the fastening against the boom, fixes the position of the fastening relative to the boom.
  • a further advantage of an outrigger according to the invention is that the cross-stays can be exactly similarly shaped, on whichever side of the boom they are to be placed.
  • the cross-stays can be exactly similarly shaped, on whichever side of the boom they are to be placed.
  • the fixing device consists of a pin affixed to the fastening and engaging in a recess in the boom.
  • the advantage of this is that the pin is pressed against one edge of the recess when the fastening, under some torsion around the boom, is pressed against the latter under the influence of the locking device.
  • the pin should preferably have an increasing crosssectional area in the direction from the point of fixation in the fastening. It is especially desirable that both pin and recess in the boom should have a rectangular crosssection, which has the advantage that the abutment be tween the pin and the edge of the recess is obtained along a relatively lengthy area.
  • the boom may consist of a unitary elongated central member, but, according to an especially advantageous further development of the invention, the elongated central member is composed of two essentially parallel tubes joined to one another by connecting elements, preferably in the form of rectangular flat bars.
  • the fastening consists in such case of a flat bar, one end of which is bent to an essentially semicylindrical section, the geometrical axis of which is transverse to the longitudinal direction of the flat bar and situated essentially in the plane of the plane part of the fastening.
  • the length of the cross-stays is so adjusted that, on attachment of the cross-stays to the boom, the fastenings are placed opposite one of the connecting elements joining together the parallel tubes.
  • the locking devices may suitablyconsist of two bolts fitting into open holesboth inthe fastenings and in the connecting element. This ensures an extremely stable construction, and, for further strengthening of the fastening points, it is advisable to arrange supporting shoulders on the boom immediately outside the fastening'point for the cross-stay.
  • FIG. 1 shows a boat moored to an outrigger according to the invention
  • FIG. 2 a part of the outrigger showing the fastening 0f cross-stays to the boom of the outrigger.
  • an outrigger consists of two essentially parallel tubes 1,
  • FIG. 2 shows more clearly how the cross-stays 4, 5 are fastened to tubes 1, 2 of the boom.
  • a connecting element 17 extending between tubes 1, 2 there are recesses 15, 16 in tubes 1, 2.
  • the connecting element 17 can be attached to the tubes 1, 2 by any suitable means, such as by welding, or it may simply be held in position by the bolts 8.
  • These recesses are designed to take pins 13, 14 placed on fastenings for the cross-stays 4, 5.
  • the fastenings are integrally connected to the cross-stays 4, 5 in any convenient manner for instance, by welding.
  • Each of the fastenings consists of a flat bar with a plane section 18, 19 and an essentially semicylindrical portion 11, 12.
  • the holes l5, 16 must be rather larger than the cross-sectional area of the pins 13, 14.
  • the cross-stays As the cross-stays are shown in FIG. 2, the righthand cross-stay 4, on assembly and! disassembly, must be so turned that the plane section 18 of the fastening device slopes obliquely downwards. After the pin 14 has been inserted as far as possible into hole 16, the cross-stay 4 is turned so that the plane section 18 of the fastening is brought up against the connecting element 17.
  • an outrigger boom assembly for the mooring of boats, the improvement comprising a detachable stay which on a first end is provided with a device such as a hinge for hinging the stay in a frame such as a jetty, and which on the other end is provided with a fastening member for clamping the stay to the boom in an inclined bracing direction in relation to the boom, said fastening member being shaped to fit snugly around half or less of the boom, whereby a unity member is obtained which, without any modification, can be clamped either to the left or to the right of the boom, which stay further comprises a pin affixed to the fastening member and adapted to engage a recess in the boom, said pin having an increasing cross-sectional area in the direction away from the point of fixation in the fastening member.
  • outrigger boom for the mooring of boats, said outrigger boom having an elongated central member composed of two essentially parallel tubes joined to one another by connecting elements, the improvement comprising a stay adapted to be detachably connected to said elongated central member, said stay comprising:
  • a fastening member integrally mounted on the other end of said elongated bracing member and extending therefrom at an angle thereto, said fastening member comprising a flat bar one end of which is planar and adapted to fit snugly against one side of one of said connecting elements and the other end of which is bent to an essentially semicylindrical section adapted to fit snugly around one of said essentially parallel tubes, said elongated bracing means being integrally connected to the outer surface of the semi-cylindrical section of said flat bar and extending therefrom in or parallel to the plane of the planar end thereof;
