Description

  • The present invention relates to a frame element for a trampoline. The trampoline has a first jump surface and a second jump surface. The invention relates to such a trampoline, which has a frame element according to the invention.
  • Trampolines are widely used in physiotherapy and recreational areas. Of particular importance here is the attachment of the jump surface to the frame of the trampoline. In the prior art, there are many proposals. For example disclosed WO 2015/063142 A1 a tension member for tensioning a jump cloth on a frame of a trampoline by means of an elastic rope, wherein the tension member comprises a base body having a plurality of holding elements for holding the elastic rope. In order to enable a variable adjustment of the fabric tension, it is proposed to provide a plurality of retaining elements on the same side of the base body, so that the elastic rope can be placed either around one or more of the retaining elements.
  • In addition to the design as a single trampoline with a single jump surface also exist types of trampolines in which several jump surfaces are present side by side and are attached to common frame. The individual jump surfaces are necessarily separated from each other by such frame sections. Such trampolines are used for example in venues. Because the jump surfaces are separated from one another, they are mechanically decoupled and a person jumping on a jump surface does not influence a person jumping on an adjacent jump surface. An example of a frame construction of such a design is shown in FIG WO 2013/116245 A1 given.
  • When jumping on a trampoline with several jump surfaces, such as those offered in "Trampoline Park" venues, people can jump over from one jump surface to the next jump surface. If the jump is too short, they can injure themselves on the frame separating the two jump surfaces. To reduce the risk of injury, the frames are provided with a cushion pad. Nevertheless, it is immediately obvious that an impact on a (also padded) frame is completely different than an impact on a jump surface of a trampoline. This still poses a safety risk, for example, by impact on the frame, slippage and buckling of the person's foot.
  • There is therefore still a need for improved trampolines with multiple jump surfaces. In particular, there is a need to improve the safety of such trampolines against user injury.
  • The object of the present invention is to provide such an improved trampoline.
  • This object is achieved according to the invention by a frame element for a trampoline according to claim 1 and a trampoline according to claim 7. Advantageous further developments are specified in the subclaims. They can be combined as desired, provided the context does not clearly result in the opposite.
  • The present invention will be explained in more detail with reference to the following figures, but without being limited thereto. Show it:
  • 1 an inventive frame element for a trampoline in a perspective view
  • 2 a partial view of a trampoline according to the invention
  • 3a - 3c several views of a frame element according to the invention for a trampoline
  • 4 an inventive frame element for a trampoline
  • 5 an inventive frame element for a trampoline
  • 1 shows a frame element according to the invention for a trampoline containing a first jumping surface and a second jumping surface, comprising a carrier 100 wherein the carrier has a first sidewall 110 and one of the first side wall 110 opposite and spaced from her second side wall 120 having; and a first spring 140 and a second spring 130 ,
  • The first spring 140 is adapted for connection to a first jump surface of the trampoline, so that a connected configuration is taken.
  • A "connected configuration" within the meaning of the invention means that this configuration is adopted when the spring is actually connected to the jump surface and, by the train of the jump surface on the spring, points it in a certain direction in its longitudinal direction. For the concept of connected Configuration, it does not matter if the spring is stretched out of its rest position or not.
  • An end of the first spring 140 is with the first sidewall 110 connected and the first spring protrudes with a further end through a first opening 150 from the second side wall 120 out.
  • The second spring 130 is for connection to a second jump surface 300 set up the trampoline, so that a connected configuration is taken, with one end of the second spring 130 with the second side wall 120 is connected and wherein the second spring with another end through a second opening 160 from the first side wall 110 protrudes.
  • In the case of in 1 shown frame element is the carrier 100 around a square profile. However, any support structures are conceivable as long as the first side wall 110 and the second side wall 120 be kept at a distance from each other. For example, may be the frame 100 has a quadrangular, rectangular, V-shaped or U-shaped cross-sectional profile. To achieve a weight and cost savings compared to a square profile while providing a bearing surface for covers is particularly suitable a U-profile. The opening of the U-profile preferably shows in the operation of the trampoline down.
  • It is not mandatory, but cheap, if as in 1 shown the first sidewall 110 and the second side wall 120 parallel to each other.
  • That the first spring 140 is designed for connection to a jump surface of the trampoline, in addition to a suitable for the particular application (trampoline for toddlers, trampoline for competitive athletes, etc.) sizing also includes the fact that the first spring 140 Having means which can connect to the first jump surface. In the simplest case, it may be a hook-shaped bent end of the spring, which engages in a ring or an eyelet of the jump surface. The same applies to the second spring 130 , which is adapted for connection to the second step surface of the trampoline.
  • Since in the field of application of the invention suitable springs are usually elongated, two ends of the springs can be defined. They may be referred to as proximal and distal ends, by definition the proximal end being that end which is connected to a sidewall of the frame 100 connected is. An end of the first spring 140 , which according to the terminology above represents the proximal end, is with the first sidewall 110 connected. In the simplest case, a hook-shaped bent proximal end of the first spring 140 in a hole or a double hole of the first side wall 110 intervention. The first spring 140 now protrudes through the space between the first side wall 110 and second side wall 120 through and over a first opening 150 from the other side of the second side wall 120 out. The same applies mutatis mutandis with respect to the second spring 130 which, as shown here, are parallel, but in relation to the proximal and distal ends, and thus in relation to the position of the hawser to be connected thereto, opposite to the first spring 140 runs.
  • Of course, the advantages of the invention come with a plurality of first springs 140 and a plurality of second springs 130 as part of 100 especially effective. It is preferred that the first springs 140 each parallel to each other and the second springs 130 also each parallel to each other.
  • In the figures, the frame element according to the invention is shown linear. However, it is also possible that the frame member is bent, angled or includes one or more branches.
  • 2 shows a detail of a plan view of a trampoline according to the invention, which is a frame element according to the invention with frame 100 , first sidewall 130 , second side wall 120 , first springs 140 and second springs 130 having. The trampoline has one with the frame member via one or, as shown here, several of its first springs 140 connected jump surface 310 and one with the frame member via one or, as shown here, a plurality of its second springs 130 connected second jump surface 300 , The connection between the springs 140 . 130 and the jump surfaces 310 . 300 gets over at the jump surfaces 310 . 300 attached D-things 210 . 200 reached, in the hook-shaped bent distal ends of the springs 310 . 300 intervention.
  • The advantage of the frame construction according to the invention is based on the trampoline according to 2 be explained. If a jump surface is loaded, for example the first jump surface 310 , the first springs stretch 140 longitudinal. However, a part of the expansion path runs inside or below the frame element. The same applies to a load on the second jump surface 300 and the stretching of the second springs 130 , Compared to a conventional construction for such trampolines, in which the springs are mounted directly on the sides of the frame member facing the respective jump surface, a achieve considerable width savings of the frame member. A reduction in the width, in turn, reduces the likelihood of landing on the frame as it jumps from one jump surface to the adjacent jump surface, or on near-frame less flexible jump surface sections. In this way, a resulting injury risk is reduced.
  • In one embodiment of the frame element according to the invention, the first opening 150 and / or the second opening 160 dimensioned so that in the case of the first opening 150 the first spring 140 in the operation of the trampoline not the second side wall 120 touched and / or in the case of the second opening 160 the second spring 130 not the first sidewall 110 touched.
  • In a further embodiment of the frame element according to the invention, the connection of the first spring 140 with the first side wall 110 a detachable connection and / or the connection of the second spring 130 with the second side wall 120 is a detachable connection. One way to accomplish this is in 3a -C and 4 shown.
  • 3a is an upper cross-sectional view of a frame member according to the invention with frame 100 , first sidewall 110 , second side wall 120 , first spring 140 and second spring 130 , For the proximal end of the first spring 140 is in the first sidewall 110 also provided an opening through which protrudes a hook-shaped bent proximal end and by a wedge or bolt 400 is fixed positively. Likewise, for the proximal end of the second spring 130 in the second side wall 120 an opening provided through which a hook-shaped bent end of the second spring 130 protrudes, which by a wedge or bolt 410 is fixed positively.
  • 3b is another cross-sectional view of in 3a shown frame element. It can be seen that this is the frame 100 is a downwardly opened U-profile.
  • 3c is a plan view of the frame element 3a the direction of view designated A.
  • 4 is a perspective view of the frame member 3a ,
  • The first side wall 110 and / or the second sidewall 120 In the frame element according to the invention can also have bulges, to which the springs 140 . 130 be attached. The bulges extend opposite to the pulling direction of the springs. This allows the use of even longer springs with a constant general frame width. It may be provided on the respective side walls more openings to allow the springs to pass out of the frame member out.
  • In a further embodiment of the frame element according to the invention, this has ≥ 5 to ≤ 50 first springs 140 and / or ≥ 5 to ≤ 50 second springs 130 on. It is preferred that such a frame element ≥ 10 to ≤ 30 first springs 140 and / or ≥ 10 to ≤ 30 second springs 130 having.
  • 5 shows a further variant of a frame element according to the invention in a cross-sectional view. The frame 100 is designed as a U-profile with down-facing opening and has the first side wall 110 and the second side wall 120 on. In the second side wall 120 there is the first opening 150 ,
  • The first spring 140 is with its distal end on the first sidewall 110 attached. This is schematically represented by the connection 500 shown. The attachment can be done for example by a hook-shaped bent end of the spring, which in a holder on the first side wall 110 intervenes.
  • The first spring 140 is shorter than the width of the frame 100 , It is dimensioned so that its travel when operating the trampoline completely within the frame 100 lies.
  • The proximal end of the first spring 140 is by means of schematically illustrated connection 500 with the connection tab shown schematically 600 connected to a jump surface. The arrangement according to 5 shows the unloaded state of the trampoline, whose part is the frame element shown. Thus, also a connected configuration with respect to the first spring 140 shown.
  • It is inventively provided that in the connected configuration, the first spring 140 towards the first opening 150 has. Then the spring 140 also effectively cushion movements of the trampoline jumping surface.
  • If, as shown here, the spring travel of the springs completely inside the frame 100 runs, the proportion of trampoline construction, which has gaps between the frame and jump surface and thus represents a risk of injury, can be reduced. This also means that a cushion covering the frame can have a smaller width and can also contribute to a reduction in the risk of injury. In conventional construction would be a cushion for example, have a width of about 70 to 90 cm. With this frame variant according to the invention, the width of the pad can be reduced to about 30 to 50 cm. A 20 cm wide frame 100 can be enough to guide the springs completely inside.
  • Another advantage of guiding the springs within the frame is that the openings of the side walls need not be dimensioned for the springs, but only the movement of the connecting straps 600 and the like must allow. For smaller openings, the stability of the frame construction increases.
  • It is also in 5 to see that the first opening 150 is sufficiently dimensioned to even vertical movements of the connecting strap 600 permit.
  • If in the illustrated cross-sectional views only the circumstances of the first spring 140 be discussed, this of course also applies mutatis mutandis to the oppositely disposed second spring 130 ,
  • In a further embodiment of the frame element according to the invention, the length of the first spring 140 ≥ 50% to ≤ 150% (preferably ≥ 70% to ≤ 130%) of the width of the frame 100 and / or the length of the second spring 130 is ≥ 50% to ≤ 150% (preferably ≥ 70% to ≤ 130%) of the width of the frame 100 , The less the spring protrudes, the lower the area not covered by the frame or step surface of the trampoline. This increases the safety of the trampoline.
  • In one embodiment of the trampoline according to the invention, a cover made of a shock-absorbing material is at least partially arranged on the frame element. Suitable examples are flexible foams. Padding the frame further increases the safety of the trampoline.
  • It is preferred in this case that the cover on both sides of the frame 100 protrudes and continue in the resting state of the trampoline the first and / or second jump surface 310 . 300 touched. This reduces the risk for a jumping person to get between the frame and the jump surface and get injured. The resting state of the trampoline is the unloaded state of the trampoline and in particular the unloaded state of the jump surfaces.
  • In a further embodiment of the trampoline according to the invention, the first and / or second jump surface 310 . 300 pressed against the cover. The jump surface 310 . 300 can be pressed by pressure from the bottom up by means of a flexible plastic layer to the cover, for example. This also reduces the risk for a jumping person getting between the frame and the jump surface and getting hurt.
  • The trampoline according to the invention can of course be used in trampoline parks. An arrangement with a plurality of jump surfaces and a plurality of the frame elements according to the invention is then still a trampoline in the sense of the present invention.
