description

The invention relates to a safety hook for a harness used in windsurfing, the consists of an elongated hook plate with a hanging bracket attached to it.

When windsurfing, the athlete uses the harness hook to attach himself to a rope, which in turn is attached to the boom is attached. This allows him to do some of the holding work that would otherwise be done with his hands on the boom would have to do over the harness hook with his upper body.

To improve the freedom of movement of the athlete are Trapezoidal hooks with slidable suspension brackets have already been proposed which, within certain limits, allow a sliding movement of the suspension bracket across the athlete's chest. However, these facilities are due the required plain bearings are relatively expensive to manufacture. It also fulfills the sliding of the hanging bracket only to a very limited extent the desire of the athlete for an optimal adjustment of the belt attachment to the different Directions of pull of the tampen. Finally he

is given by the relative movement possible with plain bearings the parts to each other also pose a risk of injury in the event of a fall.

The invention is based gave up _y to create a Sicherhsitshaksn which is inexpensive to HersfceÜuna, allows optimum adaptation to the pulling direction and does not create any risk of injury.

According to the invention, with a safety hook of the type mentioned at the beginning, the object is achieved in that

a coupling which can be pivoted about at least one pivot axis is provided between the suspension bracket and the hook plate is * This ensures that the required mobility of the coupling is generated solely by pivoting movements in which no parts axially displaceable relative to one another are required.

According to a further feature of the invention it is proposed that the coupling be made of rubber (or a rubber-elastic Plastic) is formed and is pivotable due to elastic bending. This ensures that the Swiveling ability of the coupling through pure material elasticity is applied so that there is no need for mechanical parts that can move relative to one another.

According to a further feature of the invention it is proposed that the coupling has a hook attached to the plate rear coupling base and a suspension bracket carrying the front coupling base, the coupling section is formed is narrowed in the clutch web between the two coupling sockets. It is thereby achieved that a single, extremely simply constructed and inexpensive to manufacture elastic component provides all of the coupling functions.

According to a further feature of the invention it is proposed that the coupling longitudinal section be designed in an X-shape so that the coupling around the crosswise to the longitudinal direction of the hook plate and through the X intersection

suggest that the suspension bracket is a rotatably mounted

k has a roller whose axis of rotation is transverse to the general traction

the frictional resistance of the tampon in the harness hook is reduced, which benefits the mobility of the athlete; in addition, chafing of the pad is effectively avoided.

According to a further feature of the invention, it is also proposed that that the roller has a concave-shaped roller shell. This ensures that the rope has a receives secure guidance on the role and does not slide off the role.

Embodiments of the invention are below Described in more detail with reference to the accompanying drawings.

Fig. 2 shows the safety hook according to Fig. 1 in view,

Fig. 3 shows the safety hook according to FIG. 1 in side view, and

FIG. 4 shows a representation similar to that of FIG

3 shows a modified embodiment the safety hook with a roller.

In FIGS. 1 to 3, the same hook plate 1 The suspension bracket 3 is attached via a coupling 2.

The coupling 2 is made of elastic rubber and has as can be clearly seen in FIG. 1, an X-shaped longitudinal section. This results in the area of the X intersection a cross-sectional constriction through which the coupling 2 receives a desired bending axis which is transverse to the longitudinal direction the hook plate runs. With different pulling directions of the hooked in the suspension bracket 3 (not shown) trapezoidal ramming, the clutch 2 adjusts itself to the pulling direction by elastic bending.

The suspension bracket 3 can, as the embodiment in Fig. 4 shows, be provided with a rotatable roller 4, which reduces the friction of the trapezoidal ramming in the suspension bracket 3. This makes it easier for the athlete to surf performing movement work.

Instead of the rubber-elastic coupling, other types of coupling can also be used, provided they are articulated act like a cardan coupling. It is apparent, however, that the embodiment described is particularly It is advantageous because the coupling does not have any parts that move relative to one another, which means that the coupling emanating from the coupling Risk of injury is reduced.
