Definitions

  • the invention relates to a tensioning device for a support network, in particular between the hull of a catamaran, wherein the support network is fastened on two opposite legs of a tenter tensile strength.
  • the frame connecting the two hulls often has at least one support net bridging the distance between the two hulls, which is tensioned between opposite legs of a tenter formed by the connecting frame.
  • This support network is connected to the opposite clamping frame legs tensile strength, the support network can be clamped or lashed.
  • the support net is laboriously stretched before its attachment, which makes it difficult to maintain an advantageous clamping force. This is particularly important in collapsible catamarans in the weight, because yes, when disassembling the catamaran in general also the two hulls connecting body together is broken down and thus the tenter can no longer fulfill its task.
  • the invention is therefore based on the object, a clamping device for a support network, in particular between the hulls of a catamaran, in such a way that a sufficient voltage of the support network can be ensured without being dependent on the applied hand force with respect to the mains voltage.
  • the invention achieves the stated object in that one of the two legs acts as a clamping leg about a parallel to its longitudinal axis Swivel axis is rotatably mounted in the clamping frame, which runs at a tensioned Tragnetz on the Tragnetzseite at a distance from the discharge line of the support network from the clamping leg, and that a locking device is provided for the clamping position of the clamping leg.
  • the tensile leg acting on the clamping leg support network can be stretched by a simple pivoting of the clamping leg, without special use of force, because the arrangement of the pivot axis with respect to the flow line of the support network from the clamping leg in the sense of a lever ratio can be chosen so that the application of a corresponding clamping torque is ensured by a comparatively small hand force.
  • the locking device comprises a radially spaced from the pivot axis of the clamping leg stop for the clamping leg and a bolt which is spring-loaded in the locking direction on the clamping leg and the stop in engages behind the locking position.
  • the preferably forming a part of the locking device stop for the pivoting clamping leg not only determines the clamping position for the clamping leg, but can also be used to secure this clamping position when the clamping leg provided latch engages behind this stop, because then the clamping leg is no longer from the stop can be swung away.
  • the effective locking in the spring action of the bolt ensures its locking position and at the same time allows easy unlocking.
  • the clamping leg may have a longitudinal groove for receiving a peripheral portion of the support network forming profile and two pivot bearings for the clamping leg end caps for the profile, of which at least one of the clamping leg associated part of the locking device is provided.
  • the clamping leg can be easily adapted to the respective network length by the profile is cut to length.
  • the end caps that can be inserted in or on the profile have all the construction parts that are needed for the storage and locking of the clamping leg in the tenter. These end caps can also complete the receiving groove for the edge strip of the support network, so that no additional measures are required for the axial securing of the support network.
  • the pivot bearing can form open bearing shells in the end caps of the clamping leg, which allows easy removal of the clamping leg of the stubs of the pivot axis. In the clamping position, the bearing shells are pulled against these stub axles, so that a secure hold for the clamping leg is ensured within the tenter.
  • Fig. 1 the catamaran shown on two hull 1, which are detachably connected together by a frame 2.
  • This frame 2 has two connecting struts 3, which carry a central longitudinal beam 4 and end receiving clamping leg 5, each forming a clamping frame for a support network 6 with the longitudinal beam 4 and the connecting struts 3.
  • the two Tragnetze 6 are each tensile with the longitudinal beam 4 and the associated clamping leg 5 is connected.
  • the clamping legs 5 are each composed of a profile 7 and the profile 7 end-capping end caps 8, which form a bearing half-shell 9 for pivotal support on a pivot shaft 10 formed by stub axle on the connecting struts 3.
  • the profile 7 comprises a longitudinal groove 11 for receiving an edge portion of the support network 6, which is held by means of a welt 12 in the longitudinal groove 11.
  • the pivot axis 10 extends for the clamping leg 5 on the net side with distance from the discharge line 13 of the support network 6 from the clamping leg 5, so that by pivoting the clamping leg 5 about the pivot axis 10, the support network 6 is tensioned or loosened depending on the pivot direction, because the drain line 13 of the support network 6 from the clamping leg 5 from the opposite longitudinal spar 4 or approaches it, as in the Fig. 4 from the clamping position shown in full lines and the dash-dotted lines indicated relaxation position for the support network 6 can be seen.
  • the connecting strut 3 is provided with a bolt-like stop 14 for the clamping leg 5, to which the end cap 8 is held tightly by a locking device 15, which is preferably provided only on one side of the clamping leg 5, so for unlocking not two with considerable distance from each other at the two ends of the clamping legs 5 arranged latch 17 must be operated.
  • the bolt-like stop 14 engages in the clamping position of the clamping leg 5 in a corresponding receiving recess 16 of the end cap 8 and is held in this receiving recess 16 by means of a spring-loaded latch 17.
  • This latch 17 is formed according to the illustrated embodiment as axially displaceable in the end cap 8 mounted locking bolt which is pressed by means of a locking spring 18 in the locking position, as in particular the Fig. 4 can be removed.
  • the substantially radially to the pivot axis 10 aligned bolt 17 thus prevents pivoting of the clamping leg 5 from its clamping position, as long as the bolt 17 is not pulled against the force of the locking spring 18 from the locking position.
  • Fig. 4 can be removed immediately, is released after unlocking the clamping leg 5 and its pivoting from the respect of the tensile forces an over-center position determining clamping position of the clamping legs 5 to be lifted from the pivot axis 10.
  • the two Tragnetze 6 can therefore be removed together with the clamping legs 5 and the longitudinal beam 4 of the connecting struts 3, to then solve the connecting struts 3 of the hulls 1.
  • assembling the catamaran is proceeded in the reverse order and attached after connecting the hull 1 through the connecting struts 3 of the longitudinal spar 4 on the connecting struts 3, before the clamping legs 5 are placed on the associated pivot axes 10 for tensioning the Tragnetze 6.
