• FIG. 6 shows a partial longitudinal section through the sports device according to FIG. 5
• FIG. 1 shows a sports device 10, which in the present embodiment is designed in particular as a sled, but basically could be used as any snow or water vehicle.
• This sports device 10 is inflated with a medium, in particular air, and it has an outer shell 15 which, in the inflated state, forms a support surface 13 at the bottom and a lying or seat surface 12 at the top
• an inflatable hose cover 20 and two crosspieces 21, 22 extending transversely through it are provided in the outer cover 15, which connect the lower support surface 13 to the lying or seat surface 12 of the outer cover 15 for the purpose of limiting the distance and shaping of the outer cover
• the outer casing 15 and the hose cover 20 are each prefabricated from two correspondingly dimensioned pairs of films 15 ', 20', 15 ", 20" which form the top and bottom of the device 10 on the one hand.
• the two-part hose cover 20 is with its film layers 20 ', 20 "have approximately the same dimensions as the associated film layers 15', 15" of the outer shell 15.
• Line pairs 15 ', 20', 15 ", 20” are welded to one another on the side circumference by means of an all-round seam 16, so that a closed chamber is formed in the hose cover 20
• the outer shell 15 is made of a hard-wearing fabric, which is coated or laminated with a suitable plastic, and the hose cover 20, which is separate from it, is made of at least one plastic film.
• the upper film 15 'of the outer shell 15 has a rough surface on the outside, So that a person sitting on it does not slip.
• the inside of this film 15 ' is coated or laminated with plastic so that it can be welded to the hose cover 20, which is separated per se, and to the lower film
• the lower film 15 is also made of a hard-wearing fabric which is coated or laminated on both sides with plastic.
• the inside of the lower film is preferably coated or laminated with the same plastic as the inside of the upper film 15 '.
• the lower side of the lower film 15 is coated or laminated with a very smooth plastic so that the sports equipment glides well on snow or water
• the upper film 15 'of the outer casing 15 consists of a Gordura and / or nylon fabric coated with polyurethane TPU, while the lower film 15 ", 55" consists of a hard-wearing Keflar, Teflon or nylon Fabric is made, the inside of both foils being coated or laminated with polyurethane TPU.
• This outside surface of the upper foil, which forms the seat surface, is uncoated, while this outer surface, forming the sliding surface, of the lower foil 15 ", 55" with a PVC or provided with good sliding properties TPU plastic coated or is laminated
• the hose cover 20, in turn, is made of polyurethane TPU, preferably without added fabric. This combination of materials has the particular advantage that these two different shells can be welded together very well.Of course, other materials could be used which have the required properties for this sports device 10 do justice
• connecting webs 21, 22 running approximately symmetrically to the longitudinal central axis of the outer shell 15 are provided.
• These connecting webs 21, 22, which are likewise made of a plastic coating corresponding to the fabric, are in each case at the bottom of the support surface 13 and above at the seat surface 12 together with the Outer sleeve 15 and the tubular casing 20 are welded to form a longitudinal seam 17, 18, through which a longitudinal bead is produced in the middle and one is produced on the outside.
• a continuous longitudinal seam 17, 18 results, according to FIG. 1, in a uniform, linear gap between the beads
• the outer shell 15 forms a mattress shape in the inflated state, as shown in FIG. 1, and it is tapered laterally towards the front.
• a handle 11 is attached to it on both sides. This has the further advantage that, in particular, this outer shell 15 has no problem such additional parts, such as handles 1 1, eyelets, bags or the like can be attached without causing sealing problems, since the hose cover is separated from these additional parts. Only the valve 14 extends through the outer casing into the interior of the hose

• the two outer runners 32 are not straight, but are bent outward with a radius R, so that A driver can shift his weight onto the inside of the sled and thus create more pressure on one of these two runners 32.
• This slightly waisted design of the runners 32 means that the sled automatically generates a curve when the weight is shifted to one or the other of these runners R is preferably on the order of 5 to 20 meters
• a profile plate 35 with a plurality of T-grooves 36 arranged next to one another for the reception of indicated runners 37 is welded in as a variant on the support surface 13 of the outer shell 15 can be.
• FIG. 5 shows a sports device 50, which is constructed essentially the same as that according to FIG. 1. The same reference numerals are therefore used when the parts are the same.
• an outer casing 55 and a tubular casing 60 are provided, which are interconnected and form a single film.
• An upper and a lower film are again provided, which weld to one another laterally by an overlap 56
• the outer shell 55 is made of a durable fabric, which in turn is coated or laminated with plastic.
• the upper film 55 ′ has the rough surface on the outside with the hard-wearing fabric 56, on the inside 57 it is coated or laminated with plastic and forms the tubular casing.
• the lower film 55 is also made of the hard-wearing fabric 56, moreover - forming the tube cover - coated or laminated on the inside 58 with plastic, and on the outside 59 - forming the sliding surface - provided with the correspondingly slidable plastic
• this sports device 50 is advantageous in all the places where 55 additional parts, such as runners, handles 1 1, Eyelets or the valves 14 are attached, in each case a separate film piece 52, 53 is fastened, in particular welded, to the inside of the hose cover 60, so that an additional seal is produced at these points
