Description

The invention relates to an additional device for a surfboard.

Surfboards have recently become extremely popular, which is due, among other things, to the fact that the special art of sailing with the surfboard can be learned or practiced relatively easily by everyone after an acceptably short time, and that such a surfboard that represents sports equipment is not only easy to transport, but also - compared to, for example, a sailboat _- much easier to bring to generally accessible water surfaces.

Such surfboards, however, have so far only been able to stand up, i.e. be used while sailing, or in a lying position of the user, in the latter position the detachable sail of the surfboard is removed and the hands are used in the manner of a paddle or rudder for locomotion. This is often perceived by some users as a disadvantage because it limits the use of the surfboard, which is particularly noticeable in some situations, such as when the wind is calm or the water surface is completely calm.

The invention is therefore based on the object to provide an additional device for a surfboard, which makes it possible to use the surfboard even in a seated position, in particular for paddling, and which is simple and fast, even for inexperienced users, to attach and to again solve is.

This object is solved by the features of claim 1. Advantageous refinements of this are described in the further claims.

The additional device designed according to the invention for the surfboard consists in that it is designed as a seat which can be attached to the top of the surfboard and detachably fixed there by means of fastening means. The seat can be designed, for example, as a simple plastic shell, possibly with a suitable waterproof seat cushion, and can have any possible shape.

The detachable fastening means for the seat can also be designed in any suitable form, provided that it is only ensured that the seat can be attached to the surfboard quickly and easily and can also be detached again. According to preferred embodiments of the invention, the fastening means can consist of belts, in particular rubber or plastic belts, suction cups on the underside or lateral clamping jaws. All these possible fastening means have the decisive advantage that if the seat is to be attached to the surfboard with the sail removed, it does not damage this surfboard in any way on its sensitive surface.

In the case of the fastening means being designed as elastic belts, these belts can be put on the underside of the surfboard. It is advantageous here if a hook or the like is attached to the respective belt end, which can be hooked into an edge eyelet of the seat. In order to connect the straps captively to the seat, according to a modified embodiment, the elastic straps can be firmly attached at one end the associated side edge of the seat in question, the other free end of the straps then having, for example, the hook which can be hooked into the seat eyelets. Since surfboards with different widths, in particular 62-69 cm in width, are on the market, it is advisable for the elastic straps to be adjustable in length to adapt to such different surfboard widths, for example in the manner of a belt.

The straps can be arranged on the underside of the surfboard in such a way that, for example, two straps are provided, which are either attached to the seat running parallel or running crosswise. With the crossover arrangement of the belts, it is also possible to connect them permanently at their crossing point, for example by means of welding, gluing or quilting and the like.

In the case of the design of the fastening means for the seat as suction cups, these are expediently attached to the underside of the seat, for example in such an arrangement that they run at least along the edges of the seat, in order thereby to provide secure mounting and at the same time support surface for the seat guarantee. In this context, it is of course possible to provide the entire underside of the seat with suction cups. A particularly secure and, at the same time, easily detachable holder is obtained when some selected suction cups can be forcibly ventilated and also re-aerated by a lever or other actuating device connected to them. Such an actuator in connection with suction cups is known elsewhere, for example in the case of suspension hooks.

If, according to a further embodiment of the invention, the fastening means for the seat consist of elastic clamping jaws, they are attached to the side of the seat, in such a way that they grip around the associated edge of the surfboard from above in a clamping manner. It is advantageous if the jaws are adjustable in their jaw width so that they can be quickly and easily adapted to different surfboard thicknesses.

In a practical embodiment, a total of four clamping jaws, two each at one location of the seat, are provided. The clamping jaws arranged on one side of the seat can in this case be designed to be pivotable, as a result of which the assembly and disassembly of the seat with respect to the surfboard is possible even faster and more easily.

If desired, the jaws provided on each side of the seat can be combined to form a continuous jaw strip, so that this ensures that the seat is attached to the surfboard along the entire line of its respective side edge. Of course, it is also possible, if desired, to combine two or more of the aforementioned and also other suitable fastening means with one another, should this prove to be desirable for certain applications.

The seat designed as an additional device for the surfboard expediently has a backrest, which is not only designed to be foldable, but can also be adjustable in its inclination. Furthermore, it is possible to provide the underside of the seat with support strips which run in the longitudinal and / or transverse direction of the seat, it being possible, if necessary, to provide knobs to improve the support surface. Finally, the rear edge of the seat can also be provided with a support edge, which ensures movement-free and thus safe support of the seat and the user located therein, in particular when paddling and the reaction forces caused thereby.

If desired, the seat can be provided on both sides with fold-out or telescopically extendable cantilevers, which serve to rest on the water surface and both improve the stability of the surfboard provided with the seat and also help to make it easier for a person floating in the water to get on the surfboard or can get into the associated seat.

According to a further embodiment of the invention, the seat can also be designed to be inflatable and accordingly have an inflatable seat and back part. The seat part and the back part can either be designed separately; instead it is also possible for the seat part to be integral with the back part. The back part of the seat is expediently wedge-shaped, so that on the one hand there is good leaning and on the other hand it is ensured that the forces exerted by the body on the seat have a stabilizing but not a destabilizing effect.

For the purpose of a secure mounting, the seat can furthermore be provided with a non-slip underside, wherein according to an expedient embodiment the non-slip underside of the seat consists of a rubberized mat or the like provided with knobs, which is welded to the seat.

As already explained, the fastening means for the seat can have different configurations. Thus, it is also for an extremely fast fixing of the seat on the surfboard or for an extremely quick release thereof within the scope of the invention to use Velcro strips as the fastening means for the seat, the parts of which interact with one another - loop part on the one hand and hook part on the other - on the underside of the seat and are attached to the top of the surfboard.

Furthermore, it is also possible to attach the seat to the mast joint of the surfboard by means of suitable means or to provide an additional hole on the surfboard, which in turn provides an attachment option for the seat e.g. by means of a bayonet lock, clamping, etc., offers. Finally, a glued-on foot plug part with a lockable counterpart can also be provided under the seat.

As can be seen from FIGS. 1 to 3, the only schematically illustrated surfboard 1 is designed in the usual way as a streamlined shaped board and in its upper side, approximately at the level of the first third, with a bore 2 for receiving a sail mast, not shown, and on provided a tiller 3 on its underside near the rear end of the board.

The described additional device for the surfboard 1 is designed as a seat 4, the ent shell-shaped plastic speaking hardness is shaped and can be attached to the top of the surfboard 1. This attachment j, of the seat 4 on the surfboard 1 is advantageously carried out in the area of the center of the surfboard, in order to avoid greater instabilities when climbing the seat 4 and also when the surfboard 1 equipped in this way is moved, for example by means of a paddle.

The seat 4 is provided with a backrest 5, which is designed to be foldable and its inclination can also be adjusted in the direction of the double arrows 6. For this purpose, the backrest 5 is connected to the seat 4 near its lower end on both sides in the usual manner by means of a lockable hinge fitting 7.

For the releasable fastening of the seat 4 to the surfboard 1, two elastic straps 8, 9, for example made of rubber or plastic, are provided, which are guided over the underside of the surfboard 1 and are fixed with their ends to the two side edges of the seat 4. For this purpose, the end of each belt 8, 9 is provided with hooks 10 which are hooked into the eyelets 11 of the seat 4 on the edge, so that due to the elasticity of the belts 8, 9 the seat 4 is fixed, but releasably, on the surfboard 1. Although not shown in detail, the straps 8, 9 can, of course, be designed to be adjustable in length to adapt to different surfboard widths.

To improve as well as to make the seat 4 on the upper side of the surfboard 1 more comparable, the seat 4 is provided on the underside, as can be seen particularly clearly from FIG. 2, with two support strips 12 which extend in the longitudinal direction of the seat 4 run near the respective side edge and consist of resilient material, for example rubber.

Furthermore, in the manner shown in FIG. 1, the seat 4 is provided on its rear edge with an elastic support edge 13 which prevents the seat 4 from tipping backwards and ensures good support against the reaction forces which occur, for example, when paddling.

4, the elastic belts 8, 9, which are each provided at their ends with the hooks 10 which can be hung into the seat eyelets 11, are arranged in a crossed position and approximately at the level of their center with a connection point 14 permanently connected, which prevents the loss of a single belt 8 or 9. This connection point 14 can be configured in any customary manner and can consist, for example, of a stitching point, adhesive point or the like.

In the further modified embodiment according to FIG. 5, the seat 4 is provided on its underside with a plurality of suction cups 15 which are attached along the edges of the seat 4, but also, as in the exemplary embodiment shown, also run diagonally over the underside of the seat. Such a type of fastening of the seat 4 on the surfboard 1, provided in the form of suction cups 15, can advantageously also be used in combination with other fastening means, in particular with those according to FIGS. 1-3 or 4.

In the further modified embodiment according to FIG. 6 provided as a fastening means for the seat 4 jaws 16, which are attached to the side of the seat 4 and can grip around the associated edge of the surfboard 1 from above. As indicated on the right in FIG. 7, each side of the seat 4 has two clamping jaws 16, each of which is attached to the front or rear end of the seat side edge. The total of four jaws 16 are made of resistant, elastically resilient material and designed in such a way that on the one hand they can be easily clamped onto the associated surfboard edge, on the other hand they also hold well and are also easily removable therefrom.

In order to improve the clamping fit of the jaws 16 on the edge of the surfboard, the jaws 16 are, in a modified embodiment, as shown in the left part of FIG. 6, adjustable in their mouth width, such a configuration also facilitating the adaptation to different surfboard thicknesses . For this purpose, the jaws 16 in question are provided with a through hole 17 which is penetrated by the longer leg 18 of an L-shaped angle piece 19. The shorter leg 20 of this L-shaped angle piece 19 is placed on the underside of the jaw 16. The longer leg 18 of the L-shaped angle piece 19 is provided with an external thread onto which a wing nut 21 is screwed. Depending on how strongly or how weakly the wing nut 21 is tightened, the shorter leg 20 of the L-shaped angle piece 19 accordingly lies more or less strongly on the underside of the clamping jaw 16, so that the jaw width of the jaw is also increased accordingly is changed.

As can also be seen from the left part of FIG. 6, the clamping jaws 16 provided on the relevant side of the seat 4 are designed to be pivotable, for this purpose the connection between the clamping jaws 16 and the seat 4 is not formed in one piece, but via a hinge 22 or a joint or the like. takes place, which can be unlocked or locked in the usual manner.

Instead of providing two or more individual clamping jaws 16 at each point of the seat 4, the modified embodiment shown in the left part according to FIG. 7 has a configuration such that a single continuous clamping jaw strip 23 is provided, which is firmly connected to the relevant side edge of the seat and also acts like the individual jaws described above, ie can clamp around the edge of the surfboard 1 from above.

As can also be seen from FIG. 7, the. Fig. 2 and 6 provided support strips 12 which extend near the side edges of the seat 4 on the underside in the longitudinal direction, arranged such that they extend in the transverse direction near the front and rear edges of the seat 4. In the embodiment according to Fig. 8, the seat 4 is finally provided on both sides with telescopic arms 24 which serve to support stability on the water surface for reasons of stability and are retracted laterally into the body of the seat 4 in retirement. For this purpose, the actual cantilevers 24, designed as floating bodies, are connected to the seat side surface via a linkage 25, which consists of guide elements or sleeves which can be telescoped into one another. As already mentioned at the beginning, it is also possible in this context to replace the teles cantilever extendable arms 24 to provide such arms that can be folded out laterally from the rear of the seat 4 or its backrest 5.

As can be seen from the further modified embodiment according to FIG. 9, the seat 26 shown is inflatable and therefore consists of a corresponding inflatable plastic film or the like. The seat 26 consists of two separate parts, a seat part 27 and a back part 28, these two Parts 27, 28 are non-detachably connected, in particular welded. The back part 28 is wedge-shaped in the manner shown with an upwardly tapering shape.

The seat 26 is formed non-slip on its entire underside and for this purpose has a corresponding mat 29 made of rubber or the like on the underside, which in turn is provided with knobs 30 on the underside. The knob mat 29 is permanently welded to the underside of the seat 26, for example vulcanized.

In the embodiment according to FIG. 10 modified from FIG. 9, the seat 26 shown is designed in such a way that the seat part 27 and the back part 28 of the embodiment according to FIG. 9 are formed in one piece. In this seat 26 'too, a mat 29 provided with knobs 30 is welded to its underside in order to improve the stability and also the slip resistance of the seat 26'.

All of the seats 4 or 26 or 26 'shown can, in a modification of the fastening means described so far, also be able to be fixed on the surfboard 1 in such a way that they are not fixed Velcro strips shown in more detail are used, the interacting parts of which can be attached to the underside of the seat or to the top of the surfboard and, in the known manner, ensure fast and secure fixing of the seat in question on the surfboard 1.
