Oils innovation concerns a boom for a sailboard or the like, Consists of two fork struts, which are connected to each other at both ends by a connector. ~ "

The boom on a sailing board or the like is used to operate and tension the sail * For this reason, the length of the boom must be adapted to the sail width wide sails can be raised. Inevitably must then also on. a boom adapted to the respective sail can be converted, i.e. each sail size needs its own boom. This is expensive in terms of storage, transport and costs.

The task of the innovation is therefore to make the boom adaptable to the respective sail size.

This object is achieved by the innovation in that an extension piece is provided to lengthen the fork struts is.

The advantages achieved with the innovation are in particular that an existing boom through the extension piece can be adapted in length to the sail. It is therefore sufficient to use a standard harness and corresponding extension pieces to achieve the correct length of the boom and thus the support of the sail. The extension piece can be easily and space-saving store and transport and is also inexpensive to manufacture. The applicability of the boom and thus the entire sailboard has been expanded in a simple manner.

Further advantages and features of the innovation are the dependent claims and to be taken from the description.

An embodiment of the innovation is shown in the drawing and Is described in more detail below. Show it:

Fig. 1 is a view of a sailboard;

2 shows the plan view of part of the fork tree with the extension piece;
3 shows the sectional view along line III - III in FIG.

Fig. 4, Fig. 3 corresponding sectional view in the other part _i with the boom extension piece.

1 shows a sailboard with a 1 that generates buoyancy

Boat body 1 shown on which a mast 2 with a sail 3> · ^ Is arranged. To operate the mast 2 and the sail 3 is used

a boom 4> which surrounds the sail 3 in an approximately elliptical shape and |

is attached at the height of the largest sail width, so that the sail | 3 "is held in an extended position. The mast 2 is with its. |

Mast foot rotatable in a mast mounting 5 on the hull 1 and | pivoted. To stabilize the orette of the sail, a Sword 6 protruding from the hull 1 below.

The length of the boom 4 must be adapted to the width of the sail 3 be. If a wider sail 3 'is to be used, then it must the boom 4 'be extended accordingly, as shown in dash-dotted lines in Fig. 1 is indicated. For this purpose, an extension piece 7 is provided, which is arranged in the boom 4 or in these is inserted. The fork tree 4 consists of two curved fork struts 8 which are each connected to a connector 9 at both ends are coupled to each other. According to FIG. 2, the connector 9 has two parallel, juxtaposed on a crosspiece 10 Connection sockets 11 on. In each connection socket 11 is a tubular Plug-in part 12 up to the stop on an externally provided stop ring; 13 inserted and fastened by means of transverse pins 14. At the Part of the plug-in part 12 protruding from the connection socket 11 an axial tongue 15 is worked out in its tubular jacket, which at the end facing the connection socket 11 is connected to the plug-in part 12 and at the free end an outwardly directed

Has latching button 16. A latching button 16 is attached to the stop ring 13, preferably in the axial direction with the latching button 16 directed nose 17 is provided. The plug-in part 12 is preferably made of plastic and, inside, with a metal tube 18 stiffened, which has a recess 19 in the region of the tongue 15, so that the tongue 15 can be bent inward by pressing the latching button 16, as indicated by dash-dotted lines in FIG.

One end 7 'of the extension piece is on the plug-in part 12 7 inserted, which is tubular and externally adapted to the fork struts 8. The extension piece 7 has at the front end a recess 20 which is adapted to the nose 17 and which surrounds the nose 17. In this end position, the pressed locking button 16 snaps into a bore 21 in the extension piece 7, so that it is secured and has a secure fit

A plug-in part 12 ″ is plugged into the other end 7 ^{fl of the extension piece 7} * of the extension piece 7, the end 8 'of the fork strut 8 is also equipped, which is plugged onto the plug-in part 12 ¹ in the above-described manner and secured by the nose 17 and the latching button 16.

It can be seen that by inserting the extension piece, which is matched in length to the difference in width of two cusps 7 the boom if extended accordingly by simply plugging it in or can be shortened by removing it. On the other hand, however, the connector 9 with its plug-in parts 12 can also be used directly be inserted into the fork struts 8 and locked. Of course, several extension pieces 7 can also be plugged together will. Furthermore, the coupling point with the extension piece 7 can also be provided elsewhere on the boom 4, e.g.

^{m in the} middle, 7 / ie in Fig. 1 is indicated. The fork tree k would then be divisible and possibly more convenient to store and transport.

Of course, in a further refinement, the extension piece 7 can also be designed in the form of a telescope and mounted in the fork struts 8 so that the desired position can be produced by pushing apart or one inside the other and set by locking. The extension pieces 7 is conceivable aüoh the fixed arrangement on one of the connector 9> ~ ^ß o- that it can be inserted with correspondingly long extension pieces 7 to the fork braces 8 in the described manner and is locked there, "
