Description

The invention relates to a trampoline track that from a multitude of interconnected, opposite the Floor-supported frame sections with continuous, there is a jumping mat held in the frame by tension springs, the individual frame sections using joints with horizontal pivot axis connected to each other are.

Such designs are from the prior art a trampoline track, for example through US-A-3,156 318 and US-A-4 730 826. The frame sections are not consistently designed in the same way. So are in the trampoline web shown in US-A-3,156,318 only the two outer of the three frame sections designed similarly, while the middle Frame portion has a different shape; in the US-A-4 730 826 is only a two part, very special Trampoline shown, only this one has two of the same type trained frame parts.

There is a big problem with such sports equipment in that these sports equipment when coming from a There are a large number of frame sections, not by individuals, or only with great effort erected and dismantled as well as in an equipment room can be transported and stowed there.

The problem to be solved with the invention in one such sports equipment now consists of doing the same thing shape it in a simple and quick way, too set up and dismantled by an individual can be and is easy to transport.

This task is solved with a trampoline track the features of the characterizing part of claim 1, wherein the frame sections are designed identically, and by means of a traction device on the joints of the Frame parts of the trampoline track attached auxiliary device the trampoline track can be set up and dismantled, under largely automatic folding.

The subordinate claims contain extensions and design variants of the invention.

It is preferably provided that the auxiliary device has a laterally arranged, angularly shaped rigid Has frame that is on its horizontal leg supported by freely swiveling wheels and one on its vertical legs are height adjustable by means of winch arranged lifting fork, with the head a pulley on both sides of the vertical legs for one also by means of a winch or the like synchronously operated traction means is provided and that the Traction means at their free end hooks, bolts or the like for hanging in the joints of the frame parts exhibit.

A preferred embodiment of the trampoline track is that every second hinge point is the individual frame sections outside the jump path Has hook for the traction device.

It is advantageous that the joints of the trampoline track Limit stops are assigned that in Viewed longitudinally alternately top and bottom below the swivel axes on the frame side parts are provided.

Through this design of the trampoline track to attach an auxiliary device can quickly, safely and in the simplest way even from one Individual assembled and disassembled and for example in transported a device room and folded it there be kept.

An embodiment of the invention is in the Drawings sketched and based on this in following also described in more detail.

The trampoline web "B" shown in FIGS. 1 and 2 exists from a variety according to the desired Device length largely identical and connected to each other, supported against the ground Frame sections I, II, III ... with continuous, by tension springs in a known manner in the frame 1a, 1b jumping mat 1.

The essential thing with this new device is that individual frame sections I, II, III ... are connected to one another via joints G ₁ , G ₂ , G ₃ ... with a horizontal pivot axis S ₁ , S ₂ , S ₃ ... are, in addition to the joints G ₁ , G ₂ , G ₃ ... stops "A" are assigned, which, viewed in the longitudinal direction of the web, alternately above and below the pivot axes S ₁ , S ₂ , S ₃ ... on the frame side parts 1a sit and allow an accordion-like folding of the entire web "B"; this transport state is shown separately in FIG. 3 in the lowered form of the lifting fork arms 7.

The gymnast comes to a stable condition for the gymnasts in that U-shaped brackets 2, 2b serve as floor support, the free leg ends 2a of which are articulated on one side on the frame side parts 1a, connected to a common pull chain K _{1 on the} back 2b and when the track is set up "B" at the end points E ₁ and E ₂ crosswise "K" are also braced by chains K ₂ , ropes or the like.

A lateral arrangement on each side of a hanging eye 3 or the like at every second articulation point G ₁ , G ₃ , G ₅ ... of the individual frame sections II, IV, VI outside the jumping path "B", starting at the first articulation G ₁ serves in Connection with the transport auxiliary device described in more detail below for easier handling of the device.

a. Ein von der Seite gesehen winkelförmiger starrer Rahmen 4, 5 ist bodenseitig 4 über frei verschwenkbare Laufräder 6 abgestützt und besitzt eine an seinen lotrechten Schenkeln 5 mittels Winde 9 o. ä. höhenverstellbare angeordnete Hubgabel 7, 8.

b. Kopfseitig beidseits an den lotrechten Schenkeln 5 ist je eine Umlenkrolle 10 für ein ebenfalls mittels Winde 12 o. ä. synchron betätigtes Zugmittel 11 vorgesehen.

c. Die Zugmittel 11 besitzen an ihren freien Enden 11a Haken, Bolzen, Stifte 13 o. dgl. zum Einhängen in die Ösen 3 der Gelenkstellen G₂, G₄, G₆... der Rahmenseitenteile 1a.

The auxiliary device has the following main construction features:

a. An angled rigid frame 4, 5 seen from the side is supported on the bottom 4 by freely pivotable wheels 6 and has a lifting fork 7, 8 which is vertically adjustable on its vertical legs 5 by means of a winch 9 or the like.

b. A deflecting roller 10 is provided on both sides of the vertical legs 5 on the head side for a pulling means 11 which is also operated synchronously by means of a winch 12 or the like.

c. The traction means 11 have hooks, bolts, pins 13 or the like at their free ends 11a for hanging in the eyelets 3 of the articulation points G ₂ , G ₄ , G ₆ ... of the frame side parts 1a.

The novel Zusammenfaltvorgang runs thereby from such a way that the mounted into the loop 3 of the hinge point G ₁ traction mechanism is wound in the direction of arrow P ₁ 11 by means of the winch 9, the joint G ₁ corresponding to P _2, and P ₂ which sets' and in the in Fig. 3 position shown moves; previously the end tensioning chains K _{2 were of course} loosened so that the floor supports 2, which remain connected by means of the common pull chain K ₁ , can rest on the frame 1a and, according to FIG. 3, between the now upstanding frame sections I, II, III ... come to rest.

After moving the traction means 11 into the eyelet 3 of the articulation point G ₃ , etc., the procedure can now be continued in the same way until the entire length "B" of FIG. 3 is folded into a "package"; the latter is then moved to the workplace with the auxiliary device 4-10. The re-erection of the entire track "B" is carried out analogously in the reverse manner; The arrow P ₄ indicates that the "package" folded like an accordion, if it should be necessary, can be raised or lowered by means of the lifting arms 7 via the winch 12.
