Description

The invention relates to a trampoline.

Trampolines are used in large numbers as sports equipment, in the field of competitive sports as well as in the field of amateur sports and leisure.

Such trampolines have a jumping cloth, which is fastened with elastic elements, in particular springs, to a frame. The typically collapsible and thus transportable frame can be flexibly placed on floors of gymnasiums and sports halls, or in the outdoor area, for example, in amusement parks.

The trampolines can thus be used by a wide group of people. In the use of such trampolines by children, however, in each case a supervisor is required because of improper use or high risk in performing jumps on the trampoline there is a risk that the user of the trampoline after a jump on the elastic elements or the frame the trampoline lands and kinks there or even falls off the trampoline. This may cause injury to the user of the trampoline.

The invention has for its object to provide a trampoline with increased security.

To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the subclaims.

The trampoline according to the invention comprises a jump cloth fixed to a frame construction by elastic elements. The frame construction is embedded in a floor. The upper part of the frame construction and / or protective elements attached there cover the elastic elements.

An essential aspect of the invention is that the frame construction is embedded in a floor, for example in a lawn of a playground or the like, so that the top of the trampoline terminates substantially flush with the top of the floor. As a result, a considerably increased security for the user of the trampoline is created, as falling from the trampoline, in particular associated with a kinking of the legs is excluded when hitting the edge of the trampoline after a jump.

The user safety is increased according to the invention by the covering of the elastic elements, in particular springs, which fix the jumping cloth to the frame construction. The protective elements provided for this purpose, on the other hand, ensure that the user's feet can emerge directly after jumping on the trampoline in the region of the elastic elements, thereby further avoiding injury to the user.

By thus achieved increased safety standard, the trampoline of the invention can also be used without supervision of children. Thus, the trampoline of the invention is particularly suitable for installation on unsupervised playgrounds.

The safety of the trampoline can be further increased by the fact that the area of the jump cloth is dimensioned so small that only one person at a time can use the trampoline and can not make any risk jumps. To avoid risk jumps can be advantageously used as elastic elements springs with reduced spring performance.

By covering the elastic elements with the protective elements, the trampoline is also secured against wanton damage, since the elastic elements, in particular the springs, only with special tools, but can not be solved by hand. In combination with a sufficiently stable damage-resistant design of the jump cloth and the protective elements, a vandalism-proof trampoline is thus created.

To install the trampoline, a pit is dug in a ground, which is covered for example with a lawn, and then set the trampoline with the frame construction in the pit. In order to avoid protection against wear, in particular by rust formation, the frame construction consists of a non-rusting metallic material, preferably of a hot-dip galvanized sheet steel construction. Trained as a sheet steel construction frame construction can be produced inexpensively by bending operations in the desired geometry. The entire trampoline can be advantageously delivered as a fully assembled unit, in which the jump sheet is fixed in advance in the frame construction with the elastic elements.

The elastic elements are preferably made of hot-dip galvanized steel springs and are therefore also resistant to wear and rust.

Also, the jump sheet is made of waterproof and preferably UV light resistant materials and is therefore also secured against wear due to weather conditions.

In an advantageous embodiment of the invention, the frame construction has a closed in the circumferential direction of the trampoline side wall. At the upper edges of the sidewall protrude edge segments as further parts of the frame construction which form covers for the elastic elements.

In addition, from the lower edges of the side walls protruding edge segments of the frame construction support elements.

The covers and the support surfaces for installation of the frame construction on a substrate are thus an integral part of the frame construction and thus easy and inexpensive to produce. In particular, in a frame construction designed as a sheet steel construction, these elements can be produced by simple bending operations.

The exposed leading edges of the covers form hard edges that could possibly result in injury to a user of the trampoline. In order to eliminate these, relatively low, risk of injury, shock-absorbing strips are attached to the front edges of the covers as protective elements, in particular, the shock-absorbing strips are designed as rubber strips.

The covers as components of the frame construction already secure the user from unwanted direct contact with the elastic elements of the trampoline. However, there is a risk of the user slipping on the smooth surfaces of the sheet steel covers, especially in the case of an outdoor trampoline when it rains.

In order to exclude such risks of use, fall protection elements are applied to the tops of the covers, which are provided from shock-absorbing materials, such as recycled material from old rubber tires and the like. These fall protection elements are non-slip and thus form safe conditions on the covers.

Particularly advantageously, these fall protection elements are designed so that they cover the leading edges of the covers of the frame structures and thus form a shock protection in this area. In this case, no separate shock-absorbing strips need to be provided at the leading edges of the covers.

FIG. 1 schematically shows an embodiment of a trampoline 1, which is integrated in a bottom 2. FIG. 2 shows in a perspective view of the frame structure 3 and the stored therein jump sheet 4 as essential Components of Trampoline 1. Finally shows FIG. 3 a cross-sectional view of the trampoline 1 mounted in the bottom 2.

Like from the FIGS. 1 and 3 can be seen, the trampoline 1 is placed in a pit so that the top of the trampoline 1 is at least approximately flush with the top of the bottom 2. In principle, the trampoline 1 according to the invention could be used indoors. Particularly advantageously, the trampoline 1 will be used outdoors, especially on playgrounds, the trampoline 1 is equipped so that it can be used without supervision. The trampoline 1 can then be placed in a pit in the ground, for example.

The jump sheet 4 is rectangular in the present case. The frame structure 3, which in the present case consists of hot-dip galvanized sheet steel and generally of a non-rusting metallic material, has a rectangular cross-section adapted for this purpose. Like from the FIGS. 1 and 3 can be seen, the frame structure 4 four at right angles to each other, closed side walls 3a. At the lower edges of these side walls 3a open at right angles to this extending edge segments, which form over the entire circumference of the frame structure 4 extending support elements 3b, with which the frame structure 3 is placed on the pit floor. The support elements 3b extend in a horizontal plane.

At the upper edges of the side walls 3a open further edge segments of the frame structure 3, the covers form 3c and so as protective elements for elastic elements, by means of which the jump sheet 4 is fixed to the frame structure 3 serve. How out FIG. 3 seen, springs 5 are provided as elastic elements. The springs 5 are preferably made of hot-dip galvanized steel. The springs 5 are hung on the one hand on an edge border 4a at the edges of the jump cloth 4 and on the other hand fixed to terminal strips 6 on the inner sides of the side walls 3a, preferably mounted.

The terminal strips 6 each extend over the entire lengths of the side walls 3a and are welded to their insides. The covers 3c formed by the edge segments of the frame structure 3 are dimensioned so that they completely cover the springs 5. In this case, the covers 3c extend into the edge region of the jump cloth 4, so that a manual release of the springs 5 is no longer possible. Rather, 1 special tools are required to release the springs 5 in integrated in the pit trampoline.

The covers 3c extend in a horizontal plane at the top of the trampoline 1 and close at least approximately flush with the top of the bottom 2 from. The covers 3c run over the entire circumference of the trampoline 1 and thus form a completely closed surface.

At the in FIG. 3 3c shock-absorbing strips in the form of rubber strips 7 are provided on the free leading edges of the covers, which prevent direct contact of the user of the trampoline 1 with the hard leading edges of the covers 3c.

FIG. 4 shows in detail the formation of such a rubber strip 7, which consists of a rubber jacket 7 a, which is mounted on a flat iron 7 b made of steel, which is attached to the front edge of the respective cover 3 c. The rubber strips 7 run along the entire circumference of the trampoline 1 and protect the user against injury, that is, the rubber strips 7 form further protective elements.

In particular, when the tops of the covers 3c become wet or damp due to rain or the like, they are slippery and may cause a risk of injury to the user of the trampoline 1. *** " In order to eliminate this risk of injury, fall protection elements 8 are provided on the upper sides of the covers 3c. This fall protection elements 8 as another Protective elements extend over the entire circumference of the trampoline 1 and completely cover the covers 3c.

The fall arresting elements 8 are fixed to the tops of the covers 3c, preferably by adhesive. The fall protection elements 8 are made of non-slip and at the same time shock-absorbing materials, such as recycled materials that are made from old rubber tires. Thus, the fall protection elements 8 form a shock protection and at the same time a protection against slipping of the user of the trampoline. 1

In the embodiment according to FIG. 3 form the fall protection elements 8 in a plane extending protective elements. FIG. 4 shows a variant of the fall protection elements 8 such that they have at their lying inside the trampoline edges 1 downwardly projecting projections 8a, which cover the leading edges of the covers 3c and thus additionally form a shock protection in the region of the leading edges. In this case, the fall protection elements 8 take over the function of the rubber strips 7, so that they can be dispensed with. The fall protection elements 8 are as shown FIG. 5 visible, rounded in the area of their inner upper edges, so that no sharp edges occur. Alternatively, bevels in this area are possible.

FIG. 6 shows an embodiment of a jump cloth 4 for the trampoline 1 according to the FIGS. 1 to 3 , It shows FIG. 6 In this case, the jump sheet 4 consists of an arrangement of intersecting bands 9. The flat bands 9 are made of polyester. In the bands 9 steel cable inserts 10 are incorporated. These steel cable inserts 10 extend over the entire lengths of the belts 9. In the illustration in FIG. 6 the protruding from the bands 9 ends of the steel cable inserts 10 can be seen. The so formed jump sheet 4 is not only water repellent and UV light resistant. Due to the bands 9 with the steel cable inserts 10, this also has a high stability. This is the trampoline 1, which is formed by the frame construction 3, the protective elements and this jump sheet 4, vandalism-proof.

FIG. 7 shows a second embodiment of a jump cloth 4 for the trampoline 1 according to the FIGS. 1 to 3 , This jump sheet 4 consists of a PVC coated mesh fabric 11, which is surrounded by an edge enclosure 4a, to which the springs 5 can be suspended. A corresponding edge enclosure 4a is also according to the jumping cloth 4 FIG. 6 , although not shown separately, available.

Also the jump sheet 4 according to FIG. 7 is weatherproof and UV light resistant. However, this jump sheet 4 faces the jump sheet 4 according to FIG. 6 a lower stability and is therefore not vandalismussicher.

The trampoline 1 according to the invention according to the FIGS. 1 to 7 generally forms a secure unit, so that it can be used especially in playgrounds of children without supervision. The safety can be increased by the fact that the surface of the jump cloth 4 is chosen so small, typically 1 m edge length at a square bed sheet 4, that only one person can use the trampoline 1 and no risk jumps are possible. The latter requirement can in particular also be met in that the springs 5 are dimensioned such that they have reduced spring capacities.
