Definitions

  • the invention relates to a fastening device for the detachable fastening of a boom to a mast of a sailing board, with a sleeve that encompasses the mast, the position of which can be adjusted according to the respective mounting height of the boom on the mast, to which the boom is attached with its front end, - with a tendon encompassing the mast, - With a clamping lug engaging between the tendon and the cuff - with a swiveling clamping lever for actuating the clamping lug, -
  • the sleeve on the mast is vertically displaceable when the clamping lug assumes a release position, and has an immovable clamping fit when the clamping lug is in a clamping position.
  • a mast boom connection which comprises a flexible tension band, which the mast is placed around the mast with a predetermined loop length corresponding to the mast circumference and which is attached to the boom head piece at the front end of the boom.
  • the boom head piece has a clamping lug which engages the mast when the boom is pivoted from a position substantially parallel to the mast into its sail position so that the mast is clamped between the tensioning strap and the clamping lug.
  • FR-OS 26 03 245 a generic fastening device for a boom on a mast is known, which has a slotted sleeve to which a clamping ring is attached.
  • the clamping ring has an eyelet, into which the head piece of a boom is inserted so that a clamping lug provided on the boom head piece, which is actuated by the boom serving as a tensioning lever, compresses the sleeve in order to hold the mast therein.
  • the mast is protected by the cuff from the direct action of the clamping lug, but the cuff of the known fastening device cannot be clamped independently of the boom position on the mast, since it is necessary for the entire boom to be pivoted to actuate the clamping lug must be changed if the mounting height for the boom on the mast is to be changed.
  • a boom fitting which has a substantially V-shaped molding as a boom head piece, on which a clamping device is provided with at least two diametrically opposed jaws, between which the mast is clamped like pliers, around the boom Fasten mast.
  • the jaws are articulated by means of a double-armed lever on the boom head piece, the free ends of the double-armed lever being acted upon by an actuating lever.
  • a boom with such a fitting can be easily attached to the mast at the intended connection height, since all the fastening parts are arranged on the boom head piece, but it is disadvantageous that such fastening devices require considerable production engineering and design effort.
  • the invention is based on the object, a fastening device of the type mentioned, in which the position of the sleeve on the mast can be changed quickly and easily according to a desired connection height for the boom, so that the sleeve of the fastening device is independent of the boom on the mast can be attached.
  • clamping lever which is separate from the boom, is pivotably arranged on the cuff and that a clamping jaw acted upon by the clamping lug is provided on the cuff.
  • the clamping lever designed separately from the boom according to the invention enables the clamping force required for a clamp fit of the sleeve on the mast to be generated independently of the boom, the clamping jaws acted upon by the clamping lever by the clamping lever not only ensuring that the clamping force is transmitted to the mast in a manner which is particularly gentle on the mast, but also creates the possibility to limit the clamping force elastically. For this it is only necessary to make the clamping jaws elastic in the direction of action of the force - for example by an integrated rubber buffer or by a corresponding spring arrangement, so that different long clamping paths, which can be caused by different mast diameters, can be compensated for by the clamping jaws.
  • clamping lever separate from the boom enables the clamping lever to be pivoted only as far as is necessary depending on different clamping paths, since the clamping lever separated from the boom does not necessarily have to have a defined end position, in contrast to the boom serving as a clamping lever. Different clamp paths can be brought about by different mast diameters.
  • clamping lever which is separate from the boom, is that both the position of the pivot axis of the clamping lever and the design of the clamping lug - e.g. as eccentric - can be chosen arbitrarily. This opens up a multitude of different constructive design options for the designer concerned with generic fastening devices, so that he can design the fastening device according to the invention more freely with regard to improved handling and increased safety.
  • the tensioning lever is mounted on the tensioning element, a tensioning band being provided as the tensioning element, the ends of which are connected to a bolt on which the tensioning lever is pivotably mounted.
  • the clamping lug is secured against unintentional loosening in different clamping positions.
  • the possibility provided according to the invention to hold the clamping lug actuated by means of the tensioning lever securely in different clamping positions also makes it possible to realize differently long clamping paths in order to hold the fastening device according to the invention securely with the same clamping force even on masts with different diameters.
  • a ratchet mechanism is arranged between the clamping lug and the tensioning lever, so that the tensioning lever can be brought into a rest position, regardless of the current clamping position of the clamping lug, in which it does not interfere with sailing.
  • the tensioning lever also with the boom attached to the cuff and in its sail position is pivotable to actuate the clamping lug.
  • Another embodiment of the invention is characterized in that the tensioning lever is acted upon by the boom, which is connected to the cuff and is in its sail position, in such a way that it holds the clamping lug in a clamping position.
  • the tensioning lever has a cam acting as a clamping lug, from which extends an actuating arm which, in the clamping position, is in its sailing position by the one held on the cuff is embraced.
  • a further exemplary embodiment of the invention is characterized in that the tensioning lever has a holding arm protruding from the mast in the clamping position, to which the boom can be attached.
  • the fastening device shown in Fig. 1 has a sleeve 10, which has a front sleeve shell 42, a rear sleeve shell 43 and a strap 48 ' includes the two cuff shells 42, 43.
  • the ends of the strap 48 ' are connected to each other with a bolt 39 on which a tension lever 60 is pivotally mounted, which carries a cam 61 in the region of its pivot axis.
  • the cam 61 cooperates with a support surface 14 which is provided on the front cuff shell 42 which serves as clamping jaws.
  • a separate clamping jaw can be provided on the front cuff shell, which is radially displaceable relative to the cuff shell and which, for example, has a radially arranged rubber buffer or a corresponding spring arrangement for mast diameter compensation.
  • An actuating arm 62 extends away from the cam 61 and forms an approximately right angle with a holding arm 63 which also extends away from the cam 61.
  • An eyelet 64 is provided in the holding arm 63, into which a hook 65 arranged on the boom 23 can be inserted.
  • the fastening device Before the boom 23 is attached to the mast 18 via the fastening device, the fastening device is first pushed to the desired height on the mast, the tensioning lever 60 being in its release position shown in FIG. 1. The clamping lever 60 is then pivoted into a clamping position, the cam 61 pressing the front cuff shell 42, which acts as a clamping jaw, firmly against the mast 18.
  • the actuating arm 62 of the tensioning lever 60 is essentially parallel to the mast 18, while the holding arm 63 projects forward with the eyelet 64, so that the boom 23 is easily inserted with the hook 65 into the eyelet 64 and into it Sailboat can be brought. Since the boom 23 now encompasses both the mast and the actuating arm 62 of the clamping lever 60, the clamping lever 60 can no longer be released from its clamping position.
  • a clamping lever can also be used, e.g. A ratchet mechanism or another suitable device acts on a cam or eccentric serving as a clamping lug, the tensioning lever then being able to be pivoted away into a rest position (not shown) after reaching the clamping position.
  • the holding device for the boom 23 can then be arranged in any suitable manner on the sleeve of the fastening device. It is also possible to pivotally attach the boom to the collar so that the collar is held captive on the boom.
