Definitions

  • the invention relates to a length-adjustable boom for surfboards, with two main spars connected by a boom head piece and two extension spars which are telescopically adjustable in these and which are connected to one another on the left side by an elastic boom end piece, and to devices for locking the spars at the length of the boom set according to the sail size one each with the ends of the main spars firmly connected inner sleeve, which has axially projecting latching tongues with radially outwardly projecting clamping sections over the end of the main spar, with radially inwardly projecting latching ring segments being formed on the ends of the latching tongues, and with one lockable of the inner sleeve, designed as a clamping sleeve, by which the locking tongues arranged on the inner sleeve are pressed together when pushed onto the inner sleeve, so that the locking ring formed on the locking tongues Snap the segments into circumferential grooves spaced on the extension bars.
  • the invention has for its object to further develop the generic boom with a view to greater functional reliability and easier handling of the locking device.
  • the boom according to the invention is characterized by a high level of functional reliability, simple handling and simple construction.
  • main spars 1 essentially consists of two main spars 1, which are connected at an acute angle to one another on the mast side by means of a fork head piece 2, and two extension spars 3, which are telescopically received by the main spars 1 and are connected to one another on the left side by means of an elastic boom end piece 4.
  • the boom is attached to the mast of a surfboard with the boom head piece 2 and held together by the sail bracing that runs from the corner between the leech and lower leech of the sail to the boom end piece 4.
  • the locking device also includes an outer sleeve 9 designed as a clamping sleeve, by means of which, when pushed onto the inner sleeve 5, the latching tongues 6 arranged thereon are pressed radially together via the clamping beads 7, so that the latching ring segments 8 formed on the latching tongues 6 are spaced into one of them Snap the extension bars 3 into the circumferential grooves 10.
  • an outer sleeve 9 designed as a clamping sleeve, by means of which, when pushed onto the inner sleeve 5, the latching tongues 6 arranged thereon are pressed radially together via the clamping beads 7, so that the latching ring segments 8 formed on the latching tongues 6 are spaced into one of them Snap the extension bars 3 into the circumferential grooves 10.
  • the end of the inner sleeve 5 fastened to the end of a main spar 1 has a collar 11 with flat end teeth 12, and the push-on end 13 of the outer sleeve 9 has corresponding counter teeth 14, the teeth 15 of which are separated by axial slots 16.
  • Handle recesses 17 are formed in the outer sleeve 9.
  • Inner 5 and outer sleeve 9 of the locking device are made as molded plastic parts.
  • the locking devices are released by rotating the outer sleeve 9 in the direction of the arrow b or c, whereby the end teeth 14 on the push-on end 13 of the outer sleeve 9 while simultaneously displacing them in the direction of arrow d and releasing the ring portions 20 of the teeth 15 on the push-on end 13 of the outer sleeve 9 from the clamping beads 7 on the inner sleeve 5 slides out of the end toothing 12 of the inner sleeve, and the outer sleeve 9 is simply pulled off the inner sleeve 5.
