Renate Felsberg née Nowak, 565o Solingen, Bunsenweg 9 Mast for sailing boards

The innovation relates to a tubular mast intended for sailboards, which has a on a cylindrical Holder attached joint is connected to the sail foot.

The masts known so far are with regard to their length parked on the greatest length of the sail of the sailboard. This is disadvantageous in that when using a shorter sail, the height of the boom to the mast and thus to the surfer is so changed » that a good sail control may not more is possible. The constant length of the mast allows the boom to be used in the event that that the board of surfers of different surfers

• ■ · ·

Body length is used, not in that for the particular Set the surfer to a favorable altitude.

The innovation aims to remedy this.

The solution to the problem is, according to the innovation, that a pipe section is placed on the holder of the joint of the mast is pushed on, on which a sleeve-shaped body axially is displaceably mounted, which can be locked in the respectively set position and which is on the pipe section The postponed mast serves as a carrier.

Thanks to the innovation, the mast can be easily adjusted to the required length in which it is accordingly the length of the sail should extend upwards. It can also change the height of the boom to be adjusted to the surfer via the mast.

An advantageous embodiment of the innovation is that

a) the pipe section on the outer wall spaced apart annular grooves and the sleeve-shaped Body on the inner wall has an annular rib with which the sleeve-shaped body with one of the ring grooves is in engagement,

b) the jacket of the sleeve-shaped body on his rear end is divided into resilient segments,

which on the outside have sloping slopes towards their free ends,

c) a clamping ring is guided on the sleeve-shaped body, which is in operative connection with the bevels of the segments stands.

After engaging the sleeve-shaped body with its ring-shaped Rib in an annular groove of the pipe section is the clamping ring on the slopes of the segments of the sleeve-shaped Body firmly pushed on, after which the latter is securely clamped on the pipe section.

The innovation is explained in more detail below in an exemplary embodiment with reference to the drawing. It shows:

Fig. 1 the mast with the elements supporting it in view and

FIG. 2 shows a detail according to A on an enlarged scale compared to FIG.

With 1 is a cylindrical holder for a rubber elastic Joint 2 denotes, which is embedded in a sailboard, not shown in the drawing Base is attached and give the mast 3 flexibility. On the holder 1 is a sleeve-shaped bearing 4 loosely stored. 5 with an existing plastic pipe section is referred to, which with its one end

is pushed onto the holder 1 or onto the sleeve-shaped bearing 4 and protrudes with its other end relative to the free end of the holder 1. On the outside, the pipe section 5 has annular grooves 6 at a distance from one another, which are also produced when the pipe section 5 is produced. A sleeve-shaped body 7, also made of plastic, is guided axially displaceably on the pipe section 5 and has an annular rib 8 on the inner wall. The rib 8 is integral with the body 7. The jacket of the body 7 is a ^»1 divides its rear end into resilient segments 9 having on the outside by their free ends bevels rising Io. The body 7 has a collar 11 at its front end. With 12, a clamping ring mounted axially displaceably on the body 7 is designated. The mast 3 is guided on the body 7 and one end is supported on the collar 11 of the body 7.

To adjust the length in which the mast 3 should extend upwards, the body 7, after previously the mast 3 has been removed from the pipe section 5, with its annular rib 8 in the corresponding The annular groove 6 of the pipe section 5 is locked and then the clamping ring 12 is fixed on the bevels Io of the segments 9 postponed, after which the body 7 is clamped on the pipe section. After that, the mast 3 is placed on the pipe section 5 pushed up until it rests on the collar Π of the body 7.
