Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The invention is explained below on the basis of the drawings. The drawings show:

[0042] FIG. 1: A schematic representation of an embodiment example of the trampoline according to the invention.

[0043] FIG. 2: Sectional view of a part of the trampoline according to FIG. 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0044] FIG. 1 schematically shows an embodiment example of the trampoline 1 according to the invention.

[0045] The trampoline 1 has a frame structure 2. This comprises a substantially rectangular frame 3 oriented in a horizontal plane. Support feet 4 open out from the underside of the frame 3 in the area of its corners. The longitudinal axes of the identical support feet 4 run in a vertical direction. The support feet 4 are used to stand the trampoline 1 on a surface, for example a floor of a hall. Supporting elements 5 are located on the undersides of the supporting feet 4 to ensure good footing on the base.

[0046] The frame structure 2 advantageously consists of a profile or tube structure made of metallic material.

[0047] A jumping mat 6 is clamped in the frame 3 of the frame structure 2. The jumping mat 6 is fastened to the frame 3 by elastic elements in the form of springs 7, as shown in particular in FIG. 2. The jumping mat 6 may, for example, be made of a woven fabric or an arrangement of crossed bands. The top side of the jumping mat 6 thus forms a jumping surface on which a user can perform jumps.

[0048] To prevent the user from landing on the frame 3 or the elastic elements during the jumps, a frame cover 8 is provided to cover the top side of the frame 3 and thus of the frame structure 2 and also the elastic elements. The frame cover 8 extends around the entire circumference of the trampoline 1, as shown in FIG. 1.

[0049] FIG. 2 shows a sectional view of the frame cover 8 according to the invention. According to the invention, the frame cover 8 has a multilayer structure made of a plurality of layers of different materials. In addition, the frame cover 8 has a location-dependent height profile. In this case, there is a location dependency in the x-direction, as shown in FIG. 2, wherein this directional arrow runs from a lateral edge of the frame structure 2 towards the center of the trampoline 1. In contrast, the cross-section of the frame cover 8 is constant in the circumferential direction of the trampoline 1 with the exception of the corner areas. In the corner areas, the frame cover 8 is extended due to its geometry.

[0050] As FIG. 2 shows, the multilayer structure of the frame cover 8 in the present case is made of two layers, namely a base layer 9 and a build-up layer 10. Both layers are formed as foam layers and thus have elastic, damping properties. The base layer 9 consists essentially of PE (polyethylene). The build-up layer 10 is made of a PU (polyurethane)-based foam.

[0051] The underside of the base layer 9 rests on the frame 3 and the springs 7 fastened thereto. Thus, the frame cover 8 completely covers the frame 3 and the springs 7, i.e. the elastic elements, up to the jumping mat 6 and thus conceals all sources of danger to which the visitor would otherwise be exposed when performing jumps on the trampoline 1.

[0052] The build-up layer 10 lies in a recess in the base layer 9, wherein this recess is provided on the top side of the base layer 9. The form of the build-up layer 10 is adapted to the form of the recess so that the build-up layer 10 abuts the interfaces of the base layer 9 without any gaps.

[0053] The build-up layer 10 is held to and secured in position on the base layer 9 by fixing means. In the present case, the fixing means are formed by adhesives or adhesive tapes, which are not shown separately in FIG. 2.

[0054] As can be seen from FIG. 2, the build-up layer 10 extends only over the area of the frame 3 and the adjoining coupling means for connecting the springs 7 to the frame 3, wherein the coupling means in the present case are hooks 11.

[0055] In contrast to the springs 7, which are elastically deformable, the rigid frame 3 poses an increased risk of injury. Accordingly, the frame cover 8 has an increased damping effect in the area of the frame 3, which is achieved by the build-up layer 10 in the area of the frame 3.

[0056] Furthermore, an increased damping effect in the area of the frame 3 is achieved by the frame cover 8 having a height profile that varies in the x-direction, as shown in FIG. 2. As can be seen from FIG. 2, the height of the frame cover 8 has a maximum value in the area of the frame 3, so that a particularly large damping effect is achieved in this area. From this maximum value, the height of the frame cover 8 continuously decreases in the area of the springs 7 to a minimum value obtained at the edge region of the frame cover 8 adjacent to the jumping mat 6. Thus, a wedge-shaped cross-section of the frame cover 8 is obtained. The maximum value is advantageously about 8 cm, the minimum value about 2 cm. In general, the height range of the frame cover 8 is in the single-digit cm range.

[0057] Since no greater damping effect of the frame cover 8 is required in the area of the springs 7, the height of the frame cover 8 steadily decreases in this area, which also results in material savings in the manufacture of the frame cover 8. Since the frame cover 8 tapers off flat towards the jumping mat 6, unwanted tripping hazards are also avoided.

[0058] As FIG. 2 shows, the protective function of the frame cover 8 is extended in that it has cover elements 12 located on the side of the frame 3 which, due to their damping effect, protect a user from bumping against the frame 3 from the side.

[0059] In the present case, the cover elements 12 have a rectangular cross-section and are fastened to the underside of the frame cover 8, for example by adhesive means. Like the base layer 9, the cover elements 12 are advantageously made of a PE foam. In principle, the cover elements 12 can also be formed in one piece with the base layer 9.

[0060] As FIG. 2 shows, the frame cover 8 is covered with a covering 13, which in the present case is made of PVC.

[0061] A roughened layer is provided on the underside of the frame cover 8. The covering 13 can be fixed to this layer, for example, by means of Velcro strips.

[0062] Furthermore, brackets 14 are pivotably mounted to fix the frame cover 8 to the frame 3. The brackets 14 are preferably distributed around the circumference of the frame 3 at predetermined distances from each other. The brackets 14 engage in pockets 15 on the underside of the covering 13 (FIG. 2) and in this way provide positional fixation of the frame covering 8 relative to the frame 3.
