Description

The present invention relates to a component for a holding device for holding at least one cloth in a state in which the cloth is clamped in a plane, a holding device with such a component and a sports device with such a component or with such a holding device.

Under a trampoline is commonly understood a sports equipment, as for example from the DE 10 2005 060 405 A1 is known. A known trampoline usually includes a frame construction, a plurality of spring elements, and a cloth or jumping cloth held within the frame structure by the spring elements. For this purpose, the spring elements usually have two opposite end portions, one of which engages the frame structure and the other on the jumping cloth, so that the jump cloth as a result of circumferentially distributed around the jump sheet spring elements, each exerting a tensile force on the jump cloth, in a held in a plane clamped state.

If such a sports equipment is used in a closed space such as a sports hall or other location with a limited area such as a free sports facility, a footprint claimed by the sports equipment proves to be a critical factor due to the limited space available. In order to be able to make better use of the available space, it is generally advantageous if a sports device requires as little floor space as possible.

It is therefore an object of the present invention to provide a component for a holding device, a holding device and a sports equipment, which allow to keep under the stress of the smallest possible footprint a cloth in a state spanned in a plane.

This object is achieved by a component having the features of claim 1, by a holding device having the features of claim 5 and by a sports device having the features of claim 8.

Unlike known components for a holding device for holding a blanket in an in-plane state, the component of the present invention is configured such that during holding of the blanket, when the end portion of the spring member is attached to the fastener, the frame member is spaced from the plane is. Here, the distance to the plane defined as usual in a normal direction to the plane. Thus, the frame member of the component according to the invention is positioned on one side of the plane in which the cloth is clamped and not as in known components wholly or partly in this plane. On the other hand, the spring element must exert a tensile force on the cloth which is also in this plane, so that the cloth can be held in this plane in a clamped state. Thus, even a point at which the spring element is attached to the fastener must lie within this plane. Since, on the one hand, the point at which the spring element is attached to the fastening element lies in the plane in which the cloth is stretched and, on the other hand, the frame element is spaced therefrom on one side of the plane and not within it, the component according to the invention occupies less in this plane Space. Consequently, a holding device according to the invention for holding a cloth of a specific surface can have a smaller extension than a known holding device for holding a cloth of the same surface, or with a holding device according to the invention can hold a cloth with a larger area than with a known holding device with the same dimensions as the holding device according to the invention. If the fastening element is arranged on an outer edge of the frame element, then the area claimed by the holding device can be minimized relative to the surface of the cloth to be held. The same applies to a sports device of the present invention in comparison to known sports equipment or trampolines.

The component according to the invention may have only one frame element or it may also have a plurality, and as many frame elements. In particular, the frame element can be identical to the frame construction of the holding device, or in some embodiments of a holding device according to the invention, only one frame element of a single component forms a frame construction of the holding device. In such cases, a holding device according to the invention may also have only one component or only one frame construction. In particular, the holding device may comprise the at least one spring element or a plurality of spring elements or the one or more spring elements may be part of the holding device. Spring elements may be formed as a metallic spring, for example as a spiral spring, or as a rubber cord or rubber rope piece.

Accordingly, the component may have one or more fasteners, and indeed any number of fasteners. The end portion of the spring element can be attached to the fastening element in any manner attachable or with the fastening element. For example, the end portion of the spring element can be releasably or permanently attached to the fastener. Thus, the fastener may be an element having an opening, such as a ring or eyelet, in which the end portion can be hooked, or a pin-shaped or bent member to which the end portion can be circumferentially hooked. Further, the end portion may be hinged or latched to the fastener. Quite generally, end sections of several spring elements can also be fastened to the same fastening element, or in the case of a holding device according to the invention or a sports device according to the invention, a plurality of end sections can be fastened to the same fastening element.

In a preferred embodiment of the component according to the invention, both the frame element and the fastening element are elongate and substantially parallel to one another or the frame element and / or the fastening element are arc-shaped. Just executed components can be used in particular for holding devices whose frame construction has at least one straight side. For example, the frame element may have an arbitrarily profiled cross-section, while the fastening element is designed as a rod or rod. In contrast, components with arcuate elements can be used for round or oval holding device.

In addition, the frame member and the fastener may be made of any material. In particular, the frame member and / or the fastener may be made entirely or partially of metal or of wood or of plastic.

In a preferred embodiment of a component according to the invention, the fastening element is designed as a wire rope. A wire rope as a fastener is advantageous because it brings both a high mechanical stability and a certain flexibility with it.

Although in the holding device according to the invention, the frame member of the component is spaced from the plane in which the cloth is held and located on one side of this plane, other parts of the frame structure may still be within that plane or with respect to the frame member on a respective other Page of this level. Preferably, however, the entire frame construction and not just the frame member is located on the same side of the plane, as this generally achieves the smallest footprint.

In general, the frame construction of a holding device according to the invention can be of any shape. Thus, the frame construction may be of rectangular or square or round or oval or triangular or polygonal shape. Advantageously, the shape of the frame construction substantially corresponds to the shape of the cloth to be held. In general, any desired shaped cloths can be held with a holding device according to the invention.

Particularly preferably, the holding device according to the invention is designed for holding two or more wipes. For this purpose, the holding device may comprise a corresponding number of frame structures, or it has only a single frame construction, which is designed to hold a corresponding number of cloths. In this case, the holding device may be provided for holding towels with different shapes. In such holders, the effect of saving space can multiply with the number of towels held. Thus, under certain circumstances, several square meters of space required for the holding device can be saved, although individual components according to the invention require a shortening of a length dimension of their frame construction of only a few centimeters. Furthermore, in such holding devices, end sections of spring elements which act on respectively adjacently arranged wipes can be fastened to the same fastening element. In contrast to known holding devices for holding a plurality of wipes, a second fastening row for the spring elements is thereby saved, which contributes to a further reduction in the space required by the holding device.

The sports device according to the invention is preferably a trampoline. Accordingly, the cloth is preferably an elastic cloth or a jumping cloth.

Although the cloth can be held in a generally randomly oriented plane, for example, this plane may include or form an angle with the horizontal, in the sports equipment according to the invention the plane is advantageously oriented substantially horizontally. In a horizontally oriented plane, the frame member or the entire frame structure may be generally above the level or the cloth or below the level or the cloth. In the case of sports equipment, the latter case is preferred in which the frame element or the frame construction is located below the plane or of the cloth, since then area, which would otherwise have to be padded for safety reasons, can be reduced. As a result of the reduction of To be padded area also an increase in security and cost savings are effected. In some embodiments of the invention with a plurality of wipes held in the same plane, only substantially pure spring surfaces are present in this plane in addition to the surfaces or jump surfaces occupied by the wipes.

In the FIG. 1 For example, a holding member device 1 provided for holding a blanket in an in-plane state is shown in a three-dimensional view. The component 1 comprises a frame element 2 and a fastening element 3 as well as a plurality of retaining elements 5.

The frame element 2 is essentially an elongate hollow profile part made of metal with a rectangular cross section. At opposite end portions of the frame member 2 holes or through holes 4 are formed, which are provided for connecting the frame member 2 with frame members of other components. These other components may be components that are similar to those in the FIG. 1 shown By the frame member 2 is connected to other frame members can be a frame construction of the holding device, wherein the frame member 2 forms a part of this frame construction and the component 1 is a part of the holding device ,

Along the frame element 2, the holding elements 5 are placed on one of the two wide side surfaces 6 of the frame member 2 with a rectangular cross-section. Also in the holding elements 5 are hollow profile parts made of metal having a rectangular cross-section, but in the present case have a greater clearance height than the frame member 2 and which are also much shorter than the frame member 2. The rod-shaped fastening element 3 extends parallel to the frame member 2 through all the holding elements 5, wherein it faces the frame element 2, in the following FIG. 2 to see inner surfaces 7 of the holding elements 5 is applied and welded or soldered to these and thereby firmly connected to the inner surfaces 7 and the holding elements 5.

On the fastening element 3 spring elements 8 can be attached, which are provided in the holding device for tensioned holding of the preferably elastic cloth. This is in the FIG. 2 seen cross section through the component 1. I'm in the FIG. 2 In the case illustrated, the spring elements 8 are metallic springs or spiral springs, but alternatively rubber parts could also be provided as spring elements 8. Like in the FIG. 2 is shown, the spring element 8 has a first end portion 9 and a second end portion 10 opposite thereto. While the first end portion 9 is formed substantially annular, the second end portion 10 in the form of a hook. With the annular first end portion 9, the spring element 8 as in the FIG. 2 can be seen, the fastener 3 circumferentially include or enclose, or by means of the annular first end portion 9, the spring element 8 on the fastener 3 can be attached or fastened by the first end portion 9, the fastener 3 comprises circumferentially or surrounds. The hook-shaped second end section 10 is intended to to attack the cloth to be held, so that the spring element 8 can exert a tensile force on the cloth. This is in the plan view of a sports equipment in the FIG. 3 to see, which is a trampoline 11.

The trampoline 11 has a total of four components 1, as shown in the FIG. 1 are shown, the frame elements 2 are connected to a square frame construction 12 of the trampoline 11. All fastening elements 3 of the components 1 are located on the same side of the frame construction 12. Together with the frame structure 12, the fastening elements 3 form a holding device 13, or the holding device 13 is formed by the four components 1. By means of the holding device 13, a cloth or jump cloth 14 can be kept in a tensioned state. For this purpose, a plurality of spring elements 8 arranged around the jumping cloth 14 engage with their second end portions 10 at an edge region of the jumping cloth 14. In order to facilitate the engagement of the second end portions 10 on the jump cloth 14, the jump cloth 14 may be provided with a plurality of hooking elements or metal reinforced eyelets distributed circumferentially, for example, in which the hook-shaped second end portions 10 can be hooked. With their first end portions 9, the spring elements 8 as in the FIG. 2 shown attached to the fasteners 3. Because all four sides of the jumping cloth 14 from the spring elements 8 experience a directed to the respective fasteners 3 force or tensile force, the jump sheet 14 is stretched and held in this state.

The tensioned jump cloth 14 is used to define a span plane of the jump cloth 14 or simply a plane 15 which is in the FIG. 4 , which is a cross section through the trampoline 11 of FIG. 3 shows, dashed lines. In other words, the jump sheet 14 is stretched in this plane 15. For example, the plane 15 may be defined by one of the two surfaces of the jump cloth 14, which are parallel to the tensile forces by the spring elements 8, or by any intervening plane parallel to these two surfaces.

When in the FIG. 4 shown normal list or arrangement or orientation of the trampoline 11, the plane 15 is oriented horizontally, while all the frame members 2 of all components 1 and therefore also the frame structure 12 are located entirely below the level 15, ie on a lower side of the plane 15. Of course the trampoline 11 are basically set up differently. For example, the trampoline 11 can be set up in a tilted orientation, in which the plane 15 forms an arbitrary angle with the horizontal. Or else the trampoline 11 can be placed turned by 180 °, so that all the frame elements 2 of all components 1 and consequently also the frame construction 12 are located overall above the plane 15, ie on an upper side of the plane 15.

While in known trampolines frame elements, fasteners and also the jumping cloth are within a range encompassed by a frame construction, in the trampoline 11 the frame elements 2 and the frame construction 12 are spaced from the plane 15 in which the jump sheet 14 is stretched. This separation of the frame members 2 and the frame structure 12 from the plane 15, in which the jump sheet 14 is clamped, is in the in the FIG. 4 illustrated orientation of the trampoline 11 due to an increased arrangement of the fasteners 3 above the frame members 2 and outside the area enclosed by the frame members 2 area. However, because now the fasteners 3 are located above the frame members 2 and not in the area enclosed by the frame members 2, this area can be reduced, resulting in a reduction of external dimensions of the trampoline 11 in horizontal directions and thus the claimed by the trampoline 11 footprint smaller becomes. Alternatively, optionally with the outer dimensions of the trampoline 11 remaining the same in horizontal directions and the same footprint, a larger jumping cloth 14 can be held by the frame structure 12 and thereby the jumping surface of the trampoline 11 can be increased. Although the fasteners 3 in the FIG. 4 are located above the frame elements 2, the use of the tramplin 11 is not hindered by the spring elements 8 as a result of the distance between the fasteners 3 and the frame members 2 remains sufficient space to be deflected downwards without bumping against the frame members 2.

This effect of saving space multiplies in sports equipment or trampolines with several held-up towels or diving towels. In particular, the use of frame elements 2 with centered fastener 3 or centered fasteners 3 allows to realize complex plant constellations with only a single component. This saves costs in production. In addition, the installation proves to be easy.

This shows the FIG. 5 by way of example, a trampoline 16 with a first tensioned jump sheet 17 and a second tensioned jump sheet 18. Both jump cloths 17 and 18 are held by a frame structure 19 which is formed from frame members 2 of seven components 1 of an embodiment, as they FIG. 1 shows. The frame structure 19 is externally of a rectangular shape, which is divided by one of the components 1 and its frame member 2 in two equal square sub-frames 20 and 21. By means of spring elements 8 which are fastened to fastening elements 3 of components 1 with frame elements 2 which form a first of the subframes 20, the first jump cloth 17 is held in the manner already described in connection with the trampoline 11. Accordingly, the second jumping cloth 18 is held by means of spring elements 8, which are fastened to fastening elements 3 of components 1 with frame elements 2, which form a second of the sub-frames 21.

Here, the arranged between the two jump cloths 17 and 18, the frame structure 19 dividing component 1 has a special role, since the frame member 2 forms both a side of the first sub-frame 20 and one side of the second sub-frame 21. Thus, first end portions 9 of both spring elements 8 can be attached to fastening elements 3 of this component 1, whose second end portions 10 engage the first jump cloth 17 and end portions 9 of spring elements 8, the second end portions 10 engage the second jump sheet 18. This is in the FIG. 6 shown, which shows a cross section through the frame structure 19 dividing component 1. Compared to two individually formed trampolines, the footprint at the trampoline 16 is smaller because the frame structure 19 dividing component 1 is assigned to two sub-frames 20 and 21 and the trampoline 16 with a total of seven components 1 therefore a total of one component 1 less than two trampolines 11th from the embodiment of the FIG. 3 with a total of eight components 1.

Although, in the embodiments described so far, the square-shaped bedsprings and the frame structures are also square or rectangular in shape, fundamentally different shapes are possible for the jump cloths as well as the frame constructions.

This shows the FIG. 7 For example, a component 22 for a holding device for holding two round cloths in a state spanned in a plane state. The component 22 has a frame element 23, which is of the form of two mutually merging and again diverging circular ring sections. A fastener 24 is placed at a location on the frame member 23 at which the two circular ring sections pass furthest into one another.

FIG. 8 shows a trampoline 25 with a frame structure 26 for holding two circular jump cloths 27 and 28. The frame structure 26 has two juxtaposed and partially merging, annular sub-frame, wherein the frame member 23 of the component 22 forms a junction or transition point of the two sub-frame. By means of spring elements 8, the jump cloths 27 and 28 are held in the manner already described in each of the sub-frame in a tensioned state. In this case, both the first end portion 9 of a first spring cloth 27 holding the spring element 8 and the end portion 9 of the second jump cloth 28 holding spring element 8 are attached to the fastening element 24.

Even with the trampoline 25 results both by the arrangement of the fastener 24 outside of the sub-frame enclosed areas as well as by attaching the end portions 9 of spring elements 8, each holding different the jump cloths 27 and 28, on the same fastener 24, a reduction of the footprint of trampoline 25.
