Description

Trampoline

Technical field

The present invention relates to a kind of trampoline.

Background technology

Trampoline as sports apparatus, specifically is used for competitive sport field and asf motor field and entertainment field by in large quantities.

Such trampoline has spring cloth, and this spring cloth is fixed on the frame bracket by flexible member, especially spring.Usually folding and frame bracket that be convenient to transport thus can build neatly can build neatly in outdoor area on the ground of gymnasium and indoor stadium or also, for example in the amusement garden.

The spring cloth of such trampoline is by the covering weave of the weaving with fenestral fabric

Constitute.Such spring cloth typically for example form by plastic optical fibre by Polyester Yarns or polyamide yarn.

So the spring cloth of structure can be reasonably and cost relatively advantageously make.For the cloth that will bounce is assemblied on the trampoline, be tightened in the frame structure by the flexible member cloth that will bounce.So assembling, new spring cloth has definite length of tightening on horizontal and vertical.At trampoline through in a few days or after the use in several weeks, this spring cloth for good and all extends about 2% to 2.5%.Even if in order to make spring cloth at this moment still in the specified standard length range, in manufacture process, make spring cloth have such size, promptly, the length of spring cloth or width are on the lower end of the specified standard margin of tolerance, thereby guarantee: even if during using spring cloth, although strain occurs, the longitudinal strain of this spring cloth and transverse strain still are in the specified standard tolerance limit.

In the application of determining, when for example trampoline was used in the competitive sport field, such extension of spring cloth was unacceptable, because the spring characteristic of trampoline can perceive the ground variation therefrom.This cloth that can cause bouncing just must be with new replacing through too short service time under such applicable cases.This means significant cost factor.In addition, frequent replacing also needs not expect high time consumption.

Summary of the invention

The object of the present invention is to provide a kind of trampoline, this trampoline can satisfy quality requirement enduringly.

In order to realize this purpose, the present invention proposes a kind of trampoline, and this trampoline has by flexible member and is fixed on spring cloth on the frame structure, and wherein, this spring cloth is made of the covering weave of the weaving of the yarn that contains low ductility.Favourable form of implementation of the present invention and suitable extend type are described in the following description.

Comprise that by trampoline of the present invention one is fixed on spring cloth on the frame structure by flexible member.This spring cloth is made of the covering weave of the weaving of the yarn that contains low ductility.

In by spring cloth of the present invention, can obtain maximum, technical load capacity enduringly, that is to say that the trampoline that is equipped with this spring cloth can use on long-time section ground under uniform power output.Therefore, especially can be applied in the competitive sport by trampoline of the present invention.For such application in top motion, can advantageously be employed just, because the little influence to power output has been unacceptable just in top motion by trampoline of the present invention.This requires by satisfying by trampoline of the present invention.

Obtained high and lasting constant power output in the following manner by spring cloth of the present invention, that is, this spring cloth is made of the yarn of low ductility at least in part.

The yarn of low ductility can comprise for example aromatic polyamide, especially contraposition aromatic polyamide, for example Kevlar (Kevlar) or p-aramid fiber (Twaron).

The yarn of low ductility can be made up of polyethylene equally.

Yarn by the low ductility be made up of carbon fiber can obtain especially little strain.

The yarn that is suitable for this low ductility of forming by shellproof silk fiber (Vectran-Fasern) (fiber of forming by liquid crystal polymer just) equally.

Particularly advantageous is that by the covering weave that the spring cloth formation of trampoline of the present invention is weaved, this covering weave is made up of the yarn of low ductility and the mixture of plastic optical fibre.Such plastic optical fibre can be Polyester Yarns or polyamide yarn, and they are generally used for making spring cloth.

By the yarn and the mixture of plastic optical fibre of low ductility, on the one hand can be given and regulate the elastic performance of the cloth that bounces.In addition, compare, obtained significant cost advantage, because plastic optical fibre is obviously cheaper than the yarn that hangs down ductility by using such mixture with the spring cloth of only forming by the yarn of low ductility.

In addition, the constant power output of spring cloth can further be promoted in the following manner, that is, the part of the covering weave of the weaving of formation spring cloth (for example band) is made that by prestretched these parts keep being out of shape and can not extending then again in the process of use trampoline.Equally, stable especially weave can be used to make the tissue that constitutes spring cloth, so that further reduce to bounce cloth extension during use.

Description of drawings

Set forth the present invention by accompanying drawing below.Wherein:

Fig. 1 illustrates the explanatory view of trampoline;

Fig. 2 illustrates the cutaway view by the frame structure of the trampoline of Fig. 1, has tightened spring cloth in this frame structure;

Fig. 3 illustrates first embodiment that is used for by the spring cloth of the trampoline of Fig. 1;

Fig. 4 illustrates second embodiment that is used for by the spring cloth of the trampoline of Fig. 1.

The specific embodiment

An embodiment of the schematically illustrated trampoline 1 of Fig. 1, this trampoline 1 have the frame structure 2 and the spring cloth 3 that is bearing in this frame structure 2 as critical piece.

This frame structure 2 is made up of with the leg 5 that this framework 4 is connected with some the framework 4 of a rectangle basically, and these legs 5 are used to build at ground.Usually, frame structure 2 can be folding at this.

As shown in Figure 2, this spring cloth 3 is tightened in the framework 4 of this frame structure 2., fix along the whole circumference of spring cloth 3 as the spring 6 of flexible member, these springs are fixed on the inboard of framework 4 then for this reason.

As shown in Figure 1, these springs 6 cover by covering 7, to avoid using the personnel of this trampoline 1 owing to contact and injured danger with these springs 6.

Spring cloth 3 is made of the covering weave of a weaving basically.Fig. 3 illustrates first embodiment that is used for by the spring cloth 3 of the trampoline 1 of Fig. 1 and 2.At this, Fig. 3 illustrates the vertical view to the downside of the part of spring cloth 3.This spring cloth 3 is made of the structure with 8 of some intersections in this case.These are sewed up at their crosspoint place mutually with 8, so as anti-construct spring cloth 3 movably be with 8.

Fig. 4 illustrates second embodiment that is used for by the spring cloth 3 of the trampoline 1 of Fig. 1 and 2.This spring cloth 3 is made of latticed fabric 9, and this latticed fabric is surrounded by fringing 10, and spring 6 can be suspended on these fringings 10.In spring cloth 3, also there is corresponding fringing 10, although do not illustrate especially there by Fig. 3.

The covering weave (its constitute spring cloth 3) of weaving contains the yarn of low ductility, even if the cloth 3 that therefore bounces does not still have the vertical or horizontal extension that can aware after long-time the use.

In principle, spring cloth 3 can be made of the yarn that hangs down ductility fully.Under above situation, the covering weave that constitutes the weaving of spring cloth 3 is made up of the yarn of low ductility and the mixture of plastic optical fibre.These plastic optical fibres are made of Polyester Yarns or polyamide yarn.

The yarn of low ductility can be made up of aromatic polyamide.Particularly suitable is the contraposition aromatic polyamide, for example Kevlar or p-aramid fiber, and their ductility is all very low.In order to obtain high against weather, the yarn of these low ductility can have teflon (PTFE) coating.

In addition, be used to the to bounce yarn of low ductility of cloth 3 can be made up of polyethylene.An example of this class yarn is ultra high strength fiber yarn (Dyneema-Garne).

The yarn of being made up of carbon fiber is suitable as the yarn that hangs down ductility especially.These carbon fibers not only ductility are extremely low, and have the very high stability to the UV light radiation.

At last, also shellproof silk fiber can be used to form the yarn of the low ductility of spring cloth 3.Described yarn especially can be worked out with polyester.Anti-elater is the yarn of thermoplastic multifilament, and this yarn is formed by weaving by the liquid crystal polymer of fusion.

Usually also the yarn of multiple described low ductility can be combined and be used for making spring cloth 3.
