Definitions

  • the invention relates to a trampoline that has a surrounding frame and a plurality of legs that can be pivoted relative to the frame.
  • trampolines are known from the prior art. These are in particular so-called fitness trampolines that have a jumping mat and elastic rope sections with which the jumping mat is suspended from the surrounding frame.
  • the rope sections can be ring-shaped or open. It is also known to use steel springs instead of the rope sections that connect the jumping mat to the surrounding frame.
  • the legs of the trampoline ensure that the frame - and thus the jumping mat - is arranged at a certain distance from the ground on which the trampoline is set up.
  • trampoline This distance allows the jumping mat to be deflected without it touching the ground during normal operation of the trampoline. If a trampoline is not needed, it is often stowed away and for example, placed in a corner.
  • rigid legs i.e. legs that are rigidly connected to the surrounding frame
  • the trampoline takes up a certain amount of space.
  • Manufacturers have therefore started to offer trampolines with folding legs. These are legs that are connected to the surrounding frame and can be pivoted relative to the frame. If the trampoline is not needed, the legs can be folded down. This makes the trampoline narrow, so that it can be stowed away with added space.
  • a trampoline of this type is known, for example, from WO 2011/083093 A1.
  • the trampoline mentioned at the beginning is characterized according to the invention in that a plurality of support devices extend laterally from the frame and that each support device is connected to a base onto which the leg is attached in a pluggable or detachable manner.
  • the stability is increased by providing support devices that extend laterally from the frame to the outside when the trampoline is in the position of use.
  • the support devices preferably extend laterally from the frame in a radial direction.
  • Each support device is connected to a base onto which the leg can be attached.
  • the base is preferably a separate component that is connected to the support device.
  • the base can also be made of a different material than the support device. For example, it is possible to make the support device out of metal and weld it to the frame. This creates an extremely stable basic structure.
  • a base for example made of plastic, is mounted on the support device, onto which the respective leg is attached when unfolded.
  • the support device has a leg that is accommodated in the base. This increases stability even further. This is especially true if the leg slopes downwards in the position of use of the trampoline, which is considered to be particularly advantageous.
  • the position of use is the position of the trampoline in which the user can perform exercises on the trampoline.
  • the leg can be arranged essentially vertically in the position of use of the trampoline.
  • the support device preferably has a side section from which the leg extends.
  • the leg extends downwards from the side section.
  • the side section is expediently connected to the frame and extends outwards from the side of the frame when the trampoline is in use. Together with the downward-facing leg, the side section forms an L-shape, with the leg and the side section enclosing a 90° angle, for example. It should be noted that other angles are also possible, for example if the side section does not extend horizontally from the frame, but is slightly inclined downwards. Because the support device extends with one leg into the base, it gives the overall construction a high level of stability.
  • the leg is designed to be pivotable. This requires a pivot axis around which the leg can pivot.
  • a (physical) pivot axis for a leg passes through the leg. This is then particularly useful when the leg extends into the base.
  • the pivot axis advantageously extends between two inner sides of the leg. This allows a rod of the leg to be pivoted between the two inner sides, as will be explained in more detail below.
  • an advantageous embodiment is characterized in that the pivot axis passes through the base.
  • the respective leg is therefore not only pivoted around the base, but is also held by the base.
  • the pivot axis passes not only through the base, but also through the support device.
  • Such a construction is advantageously used when the support device has a leg that engages in the base and has considerable stability advantages on the one hand and advantages during production on the other.
  • the pivot axis can, for example, be inserted from the outside through the base and through the support device (or its leg) and fastened to the base. It can advantageously be provided that the leg has at least one through-opening through which the pivot axis passes. If two inner sides are provided, as described above as being expedient, each inner side preferably has a through-opening.
  • the base is supported on the support device.
  • the forces are thus introduced directly from the support device into the base and thus the leg.
  • the base is advantageously located directly on the support device.
  • the base has the primary task of holding the leg in position when unfolded. To do this, the leg overlaps the base when unfolded. When unfolded, the base is accommodated in the leg (or in one end of the leg) as precisely as possible.
  • the pivot axis passes through the base.
  • the base can support the pivot axis.
  • An advantageous embodiment is characterized in that the leg overlaps the pivot axis when unfolded.
  • the unfolded state corresponds to the position in which the trampoline is in use.
  • the trampoline can be stowed away particularly well.
  • One task of the base is therefore to support the leg as stably as possible.
  • the base can provide the pivot axis.
  • the base is designed to be radially open towards the inside.
  • the base therefore forms a radial opening that is directed towards the middle of the trampoline.
  • the opening is preferably in the pivoting plane of the leg and can be designed in a slot-like manner.
  • the leg is held to the base with a rod, which is considered advantageous in itself, the rod can be pivoted in the radial opening.
  • the support device has the task of positioning the legs to the side of the frame. The lateral position of the legs makes the trampoline particularly stable.
  • the support device advantageously ensures that the weight forces are diverted to the legs via the frame. Such weight forces can be considerable and include not only the user's own weight, but also the dynamic forces that arise when swinging or jumping on the trampoline.
  • the support device at least partially grips under the trampoline frame.
  • the frame has a round cross-section.
  • the support device can then extend over an angle of approx. 90°, for example laterally from the middle of the frame to under the frame. This means that both vertical forces and lateral forces can be supported particularly well by the support device.
  • the trampoline frame is in particular a frame made of metal, for example steel or stainless steel.
  • the support device is then preferably welded to the frame.
  • the frame can have a round cross-section. Other cross-sectional shapes are possible, for example square or elliptical.
  • the support device primarily has a supporting function. However, higher-quality trampolines are expected to meet certain design requirements. It is also important that the risk of injury is as low as possible. against this background, a further development of the invention proposes that the support device be housed in a housing.
  • the housing allows the support device to be so that it is no longer visible.
  • the design of the housing is largely freely configurable. It is considered advantageous if the housing, in particular its underside, forms the base. Because the base is used to absorb and dissipate forces, a good connection with the support device is important. In this respect, it is considered advantageous if the housing has a lower housing part and an upper housing part, which are preferably screwed together.
  • the support device is advantageously accommodated between the lower housing part and the upper housing part.
  • the lower part and the upper part can be screwed together. In this case, it can advantageously be provided that the lower housing part or the upper housing part has a threaded attachment that goes through the support device. The form fit makes the connection even more stable.
  • the upper housing part can partially or completely cover the support device.
  • An advantageous embodiment is characterized in that a cap is arranged on the upper housing part, which overlaps the frame.
  • the cap advantageously overlaps both the housing and the frame. It is preferably pushed onto the upper part of the housing.
  • the invention provides a trampoline that is stable on the one hand, but also has a high degree of flexibility due to the foldability of the legs. Stability is particularly important when unfolded. But also when folded down, i.e. when the legs are laid out, it is advantageous if the legs remain in the folded-down position, even when the trampoline is moved, for example, to be stowed away.
  • the housing advantageously has two centering lugs arranged at a distance from the base, between which the leg can be accommodated in the folded-down state.
  • the leg is expediently clipped between the two lugs.
  • An advantageous embodiment is characterized in that the centering lugs are arranged, in particular fastened, to the housing. This is advantageous both visually and in terms of manufacturing technology.
  • the housing can be made of a hard material, in particular a hard plastic, whereas the centering lugs are made of a softer plastic.
  • the centering lugs are expediently inserted into the housing, for example clipped and/or glued in.
  • Screwing is also conceivable. It was already described at the beginning that a good fit between the leg and the base is essential to avoid unwanted rattling of the legs during use of the trampoline, but also instability of the connection between the leg and the base.
  • the leg can basically be designed as a tube that is pulled over the base when unfolded. Tests have shown that there are limits to the stability of the wall of the tube. With a thin wall, the leg is light (which is desirable). However, this can lead to material stretching and thus an increasingly loose fit of the leg on the Base. A large wall thickness may have sufficient strength. However, the overall weight increases, which is also undesirable. against this background, tests have shown a particularly advantageous design in which the legs each have an insert with which the leg sits on the base when unfolded.
  • the insert can be made of plastic, for example, and/or inserted into the leg. This creates a construction that is light on the one hand and stable over the life cycle of the trampoline on the other. Reference is again made to the position of the leg on the base when unfolded.
  • the legs can be folded down in a pivot plane and have guide lugs arranged on both sides of the pivot plane, which engage in lateral recesses in the base when the leg is unfolded. This preferably positive engagement gives the assembly additional stability.
  • the guide lugs and/or the recesses can be created particularly advantageously if they are made of plastic. This means, for example, that the insert described above forms the guide lugs, while the base or the lower part of the housing forms the recesses.
  • the legs can be folded down in a pivoting plane and each have a projection arranged in the pivoting plane, which engages in a recess in the base when the leg is unfolded.
  • This central projection also provides additional stability.
  • the base has a slot-like opening, in particular a free end with a frontal and preferably slot-like opening, and in that the projection engages in the opening when folded down.
  • the projection also engages in the slot-like opening during the folding movement. This additionally guides the leg during the movement, which provides particular movement stability. It has already been mentioned above that it is possible to form the support device from a different material than the base.
  • the support device is made of metal and the base is made of plastic.
  • the support device made of metal creates great stability.
  • the base made of plastic enables a particularly good fit.
