Definitions

  • the invention relates to a length-adjustable boom for surfboards, with two through a boom headpiece connected main spars and two telescopically in these adjustable extension bars, which are through on the aft a boom end piece are connected, and one each connecting sleeve firmly attached to the ends of the main spars with a locking lever that has locking pins that at closed lever in corresponding adjustment holes at least a row of holes with the same hole spacing in the Extension bars to lock the bars on the according to the length of the boom set according to the sail size engage, the locking lever in a recess in one flat approach of the connecting sleeve arranged sunk and with its end facing the main spar on the sleeve in the direction the longitudinal axis of the same is pivotally attached.
  • length-adjustable booms of this type are those at the ends of the two main spars of the boom Connection sleeves with the locking levers for locking the Main spars with the extension spars bulky, see above that there is a risk that the surfer will be involved in sailing maneuvers injured.
  • EP-A-0 071 220 describes an adjustable length Boom, in which the two main spars with the Extension bars with each other by clamping devices can be locked by clamping nuts or clamping sleeves be operated.
  • the invention is based, the Generic boom for surfboards with a view to improve greater functional reliability.
  • the boom according to the invention enables a fine stage Length adjustment of the bars to trim the sail.
  • the Locking lever of the connecting sleeves which at the ends of the Main spars are firmly attached, ensure in the Closed position with the four in two holes in two rows of holes one in the extension bars secure locking of the main pillars with the extension bars with the strut length set according to the sail size and prevent mutual twisting of the main and Extension bars under the influence of torsional forces on the Boom.
  • the locking levers offer optimal security Locking the bars against unintentional opening Sailing maneuvers, especially when jibing.
  • a Boom end piece 4 consists essentially of two Main spars 1, the mast side through a boom head piece 2 are connected at an acute angle, and two Extension bars 3 telescoping from the main bars 1 be recorded and left aft via a Boom end piece 4 are interconnected.
  • the boom is with the boom head 2 on the mast attached to a surfboard and by the sail tension held together by the clew of the sail to the Fork end 4 runs.
  • the locking lever 7 is in a recess 14 in one flat approach 13 each connecting sleeve 6 arranged sunk and with its end 15 facing the main spar 1 with a Bracket 16 made of spring steel wire, which is in a circumferential groove 17th the connecting sleeve 6 sits and an elongated hole 18 in Fastening end 15 of the lever 7 passes through, on the sleeve 6 in Direction of the sleeve longitudinal axis 19-19 pivotally attached.
  • the Locking lever 7 has a projection 20 at its free end one of the cylindrical shape of the extension bars 3 concave curved inside 21 into which the four locking pins 8 at a distance in the longitudinal and transverse directions of the lever 17 are let in.
  • the locking lever 7 engages with the Approach 20 in a corresponding opening 22 in the A connecting sleeve 6, such that the four locking pins 8 the Adjustment holes 9 in the extension bar 3 according to the Push through the set length of the boom.
  • the connecting sleeves 6 are for the end of insertion Extension bar 3 tapered, and the shape of the in Connection sleeves 6 pivotable locking lever 7 is the Adjusted contour of the connecting sleeves.
