Description [as of August 15, 2024]

The invention relates to a trampoline frame, with a frame which has a plurality of frame segments, and with a plurality of connecting pieces, wherein each connecting piece is designed to connect a first frame segment and a second frame segment to one another and for this purpose is or can be inserted into the first frame segment with a first connecting section.

The invention is particularly directed at trampolines with a generic trampoline frame. These can be so-called mini or fitness trampolines, i.e. smaller trampolines, or garden trampolines that have a larger diameter. For the sake of simplicity, reference is made below exclusively to mini or fitness trampolines. However, the relevant description also applies to garden trampolines or other trampolines.

When it comes to mini or fitness trampolines, a distinction is made between trampolines with a spring suspension and trampolines with a rubber rope suspension. With spring suspension, a jumping mat is attached to the frame via metal spiral springs. The jumping mat is also called a jumping mat. The rubber rope suspension uses one or more elastic rope rings or (open) ropes that connect the jumping mat to the frame. The greater elasticity of such a rubber rope suspension compared to metal springs ensures a "softer" braking of the body and thus not only protects the joints, but also extends the muscular stress and relief phases when jumping, which has beneficial training effects.

The invention is directed both to trampolines with spring suspensions and to trampolines in which the suspension is designed as an elastic rope or elastic rope ring. In principle, the invention can be used in any type of trampoline, regardless of the type of design and suspension of the jumping mat and the geometry and size of the frame.

What all well-known trampolines have in common is that they have a surrounding frame from which legs extend. The jumping mat is stretched inside the frame. The legs ensure that the frame is at a certain distance from the ground when the trampoline is set up. This ensures that the jumping mat can move towards the ground with an appropriate amplitude when jumping or swinging.

From WO 2012 167 313 A1 a trampoline is known whose frame is made up of a number of frame segments. The frame segments offer the advantage that the trampoline can be transported in a space-saving manner in order to be set up on site. The trampoline can also be taken apart for storage. The known trampoline has a A number of connecting pieces are used. The frame segments are inserted into the connecting pieces to assemble the trampoline.

From DE 10 2020 102 803 B4 a trampoline frame is known whose round frame has a plurality of frame segments. The frame segments are connected to one another by connecting pieces that are inserted into the frame segments. The connection points of the frame segments are each located between two legs.

From DE 10 2020 102 802 B4 a trampoline frame is known whose polygonal frame also has a plurality of frame segments. With this frame, the connecting pieces are also inserted into two adjacent frame segments to connect them. Here, too, the connecting points are located between two legs.

Other trampolines in which frame segments are joined together with connecting pieces to form a surrounding frame are known, for example, from EP 3626315 Al or CN 213347599 U.

In the current state of the art, the legs either extend between two connecting pieces or from the connecting pieces themselves. Such multi-part frames have generally proven their worth. The multi-part design makes it possible to save on transport costs, as the space for the individual parts is significantly less than for a one-piece frame. This also applies when the legs are removable, which is also the current state of the art. Based on the known state of the art, the invention is based on the object of increasing the stability of a detachable trampoline. The aim is to ensure that the trampoline frame is stable despite being made up of several parts.

This object is achieved by a trampoline frame having the features of claim 1.

Accordingly, the connecting piece extends outwards from the frame when the trampoline frame is assembled and in its intended state. A leg extends from the connecting piece, which leg preferably extends radially downwards outside the frame when the trampoline frame is assembled and in its intended state, so that in a plan view of the frame the leg is arranged outside the frame.

The connecting pieces therefore fulfil a number of functions. Firstly, according to the invention they connect two frame segments. For this purpose, each connecting piece is designed such that the first connecting section can be inserted into the first frame segment. It has been found that inserting it creates excellent strength in the connection. On the other hand, the connecting piece does not form a thickening at the respective connection point, as is known from the prior art for connecting pieces where the frame segments engage with the respective connecting piece. In addition, a leg extends from each connecting piece. By arranging the legs outside the frame, the stability of the trampoline is considerably increased. The trampoline according to the invention is therefore less likely to tip over, even in extreme situations. The legs extend (in a plan view of the frame) outside the frame from the support device. In this regard, it should be noted that an adapter device, for example a housing or an extension, can be arranged between the connecting piece and the actual elongated, downwardly extending leg section. This applies in particular if the connecting piece is made of metal, as is considered advantageous. In that case, the adapter device can, for example, be made of plastic and connect a metal leg to the connecting piece. In principle, it is also possible to attach the leg to the extension (for example via a thread) or to attach it directly to the connecting piece.

The arrangement of the legs outside the frame creates increased stability. It was found that the arrangement of the legs not directly below the frame, but outside the frame, also exerts high leverage forces or tipping moments on the respective connecting piece and thus on the frame. Each connection point is therefore subjected to a particular degree of stress when the trampoline is in use. Even higher leverage forces occur when a holding rod is used, as is known for example from EP 3725379 B1. Such holding rods are used to hold the user during an exercise. Against this background, it is considered particularly advantageous if the first connecting section can be accommodated or accommodated in the first frame segment so that it can be moved longitudinally and is fixed against rotation. The longitudinal mobility of the connecting piece allows the frame to be easily assembled. For this purpose, the connecting piece is advantageously simply inserted into the first frame segment inserted. At the same time, the connection between the connecting piece and the first frame segment, in particular between the first connecting section and the first frame segment, is designed to be rotationally fixed. The first frame segment is therefore not rotatable about the connecting piece (with respect to the longitudinal axis of the frame) and vice versa.

Due to the rotationally fixed connection, the torsional and leverage forces that occur when using the trampoline can be easily diverted from the jumping mat via the connecting piece into the legs. In principle, the rotational stability can be created by the first connecting section being profiled on the outside, which is considered advantageous, i.e. not having a round cross-section. Preferably, the first frame segment has a first receiving section which is also expediently profiled on the inside, i.e. not having a round inner cross-section. The frame preferably has a round outer cross-section, which is generally considered preferred. These are therefore preferably frame segments with a round outer cross-section.

Preferably, the connecting piece detachably connects the first and second frame segments. This also allows the trampoline frame to be taken apart.

In a further development of the invention, it is proposed that the first frame segment is curved and that the first connecting section is also curved. The curvature is understood to be in the longitudinal extension of the first frame segment or the first connecting section. The first frame segment, together with the other Frame segments preferably have a (top view) round, all-round frame. The curve runs in this direction. Because the first connecting section is also curved, the engagement can take place over a long distance. This creates a stable connection. The lever forces described at the beginning can also be absorbed well. At this point, it should be noted that a straight connecting section is also possible in principle. However, with round frames, the insertion depth of the first connecting section into the first frame segment is limited.

An advantageous embodiment is characterized in that the first frame segment has a first curved longitudinal axis with a first radius of curvature and that the first connecting section has a second longitudinal axis with the same radius of curvature. The first longitudinal axis is curved with a first radius. The radius of curvature of the first connecting section corresponds to the first radius. This has the advantage that the connecting piece can be pushed into the first frame segment over a longer section. In the assembled state, the connecting piece and the first frame segment are in engagement over a longer area, resulting in a particularly durable and at the same time easy-to-assemble connection.

It has already been mentioned above that the connecting section is preferably profiled, i.e. not round in cross-section. This means that the connecting piece and the first frame segment are expediently in positive, in particular rotationally fixed, engagement.

(or can be brought) . Particularly advantageous is It has proven to be advantageous if the first connecting section has a web for engaging in the first frame segment. On the one hand, the web provides the required rigidity of the connecting piece. On the other hand, the web creates a stable connection which is particularly capable of absorbing the corresponding torsional and lever forces particularly well.

Preferably, the web extends in a horizontal direction when the frame is aligned horizontally. The web advantageously extends in the plane of the assembled frame. This allows a stable connection while at the same time being easy to manufacture. The web can be curved in its longitudinal direction, as already described above.

Preferably, the web has a rectangular cross-section. This creates a particularly torsion-resistant and at the same time durable connection with the first frame segment.

A preferred embodiment is characterized in that the web has a substantially constant width and/or a substantially constant thickness. The constant width and/or the constant thickness have the advantage that the first receiving section of the first frame segment can also be designed with a correspondingly constant width and/or thickness on the inside, so that a particularly good form fit is provided. If it is furthermore said that the width and/or the thickness are substantially constant, it should be noted that the

The bridge can also be rounded at its edges and corners. In addition, there may also be welding points on the web, as will be explained in more detail later.

The bridge provides excellent stability. To increase this even further, it is suggested that a support bridge extends from the bridge. This increases the rigidity of the connecting piece considerably.

The support web can be arranged perpendicular to the web. This results in a simple attachment to the web. This is particularly true if the web and the support web are welded, which is considered advantageous.

Preferably, the support bar is arranged on the underside of the bar when the connecting piece is inserted and the trampoline frame is in the correct orientation (i.e. with a horizontal frame). This makes the connecting piece particularly well able to absorb the torsional and leverage forces.

The support web preferably has the same curvature in the longitudinal direction as the web. This makes it much easier to insert into the first frame segment.

The connecting piece serves, on the one hand, to connect the first and the second frame segment and, on the other hand, to hold the leg in a position which (in a plan view of the frame) is preferably radially outside the frame. For this purpose, the connecting piece advantageously has at least one, preferably two lateral legs. Such a construction can be easily produced, for example, by bending and at the same time enables a stable Construction. The at least one lateral leg preferably extends radially outwards from the frame.

It is considered particularly preferred if the web is formed by a shaped piece which extends between the two legs. This gives the connecting piece considerable stiffening while at the same time making the construction simple. Because the shaped piece extends between the two legs, the shaped piece takes on two tasks, namely a connecting function and a stabilizing function. In this context, it should be noted that the tilting moment which occurs during use occurs around the frame. The shaped piece advantageously extends in a radial direction, preferably between the two legs, with the one-piece design ensuring the aforementioned increase in stability.

An advantageous embodiment is characterized in that the web preferably extends horizontally into the first frame segment when the frame is horizontally aligned and assembled and is aligned upright. The web preferably has a cross-section that is aligned vertically. The web therefore runs upright when the trampoline frame is aligned as intended (on a horizontal floor). It has been found that such a vertical web is particularly well able to absorb high leverage forces.

Preferably, the first frame segment has a first

Recording section for the first connection section. The

The receiving section is preferably profiled on the inside designed as already mentioned above. For example, the receiving section forms a guide for the connecting section. The guide is particularly preferably curved. The connecting section can then also be curved, with the advantage that the receiving section and the connecting section engage (or can be brought into engagement) over a large distance. This results in a stable connection. As already indicated above, the connecting section and the receiving section preferably have the same radius of curvature.

An advantageous embodiment is characterized in that the first receiving section is designed such that it supports the first connecting section (in the assembled and intended state of the trampoline) on an upper side and a lower side of the first connecting section. This means that torsional and tilting moments that occur when jumping on the trampoline are absorbed particularly well.

Preferably, the first receiving section has a guide rail in which the first connecting section is or can be received in a longitudinally displaceable manner. The guide rail allows the first connecting section to be inserted. At the same time, the guide rail supports the first connecting section in the inserted state. As already explained above, the guide rail can be curved.

To accommodate the vertical web, it is suggested that when the frame is horizontally aligned and assembled, the Guide rail runs upright. Preferably, it has a cross-section that is vertically aligned. The guide rail is also particularly suitable for receiving the upright web, which is considered advantageous in itself. In this context, it should be noted that the guide rail does not have to have exactly the same cross-section to receive a web. Rather, the connecting section can have guide ribs that are dimensioned such that they support the web. In the case of a rectangular web, the guide ribs then preferably delimit a rectangular receiving cross-section for the web.

The first receiving section can be formed, for example, by an insert which is inserted into one end of the first frame segment and firmly connected. Alternatively, it has proven particularly advantageous to form the first frame segment as a tube with a preferably continuous inner profile. The tube can in particular be made of aluminum.

Preferably, the first receiving section supports the support web, preferably on both sides. This further stiffens the connection. If the first connecting section has a T-shaped cross section, the first receiving section preferably also has a substantially T-shaped cross section. With regard to the first receiving section, it should be noted that the cross section does not have to be exactly T-shaped. Rather, the first receiving section can have an inner profile with, for example, small guide ribs, which are attached to the first

The guide ribs ensure a high degree of fit between the Connecting section and receiving section, but at the same time make it easier to insert the two parts into each other.

An advantageous embodiment is characterized in that the connecting piece has a support device which extends laterally outwards from the frame between the first frame segment and the second frame segment. Preferably, the first and second frame segments form a gap when the trampoline frame is assembled. The connecting piece, in particular the support device, can advantageously extend outwards from the frame.

According to the invention, the connecting piece has a first connecting section. In one embodiment, the connecting piece is firmly connected to the second frame segment.

In an alternative embodiment, the connecting piece is advantageously designed as a single piece and separately, i.e. it is not firmly connected to the second frame segment.

The connecting piece preferably has a second connecting section with which the connecting piece is or can be inserted into the second frame segment (preferably detachably). The first and the second connecting section advantageously extend in opposite directions and/or in the same plane. The fact that the connecting piece is made from one piece and can be inserted into the first and the second frame segment allows, among other things, a more compact packing size of the trampoline frame. It is considered particularly advantageous if the first connecting section and the second connecting section are formed in one piece. This has advantages in terms of manufacturing on the one hand and creates excellent stability on the other. Preferably, the first connecting section and the second connecting section are formed by a single continuous web which has the same curvature throughout.

At this point, it should be noted that the second connecting section can have all the features described in connection with the first connecting section. This applies, for example, to the curvature, the web and the support web. In particular, the first and second connecting sections can be designed identically. The first and second connecting sections can also be designed in one piece. In this respect, they can also have the same radius of curvature.

The second frame segment can also have the same features as the first frame segment, so that reference is also made to the relevant description at this point. This applies, for example, to the profiling. The second frame segment can also have a second receiving section (similar to the first frame segment) with the features of the first receiving section. In particular, it can be provided that the first and second receiving sections are of the same design. In general, all of the features described in connection with the first frame segment and the first connecting section should also apply to the second frame segment and the second connecting section. It has already been mentioned several times that high forces occur when jumping. Against this background, it is considered advantageous if the connecting piece is made from one piece and/or preferably consists of metal. This means that the support device and the connecting section can be welded together very well, for example. This also applies to the bridge and the support bridge.

From a cost perspective, it can be advantageous to manufacture the connecting piece in such a way that, although it technically fulfils its purpose, it remains in its raw state and is therefore not externally attractive. In this context, it has proven advantageous for the connecting piece, in particular the support device, to be at least partially accommodated in a housing, with the housing preferably at least partially enclosing the support device. The housing therefore at least partially accommodates the support device. It covers the support device, which is advantageous from a design perspective on the one hand and also opens up further technical possibilities on the other. For example, the leg can be attached to the housing. The housing can have an upper part and a lower part which enclose the connecting piece, in particular the support device.

It has already been mentioned above that the frame can form a gap between the first frame segment and the second frame segment, as is preferred in itself. It is then advantageous if the housing extends around the gap and/or at least partially covers the gap. The housing can be designed in several parts and, for example, have a protective cap that at least partially covers the gap. In the following, the invention is explained in more detail using preferred embodiments in conjunction with the attached drawing. The drawing shows in:

Figure 14 shows a fourth embodiment analogous to Figure 10. Figure 1 shows a trampoline 1 with a trampoline frame 2 according to the invention. The trampoline frame 2 has a surrounding frame 3 from which a plurality of legs 4 extend. A jumping mat 6 is attached to the frame 3 by means of elastic rope rings 5. For this purpose, hooks 7 are arranged on the underside of the jumping mat 6, into which the rope rings 5 are hooked.

Figure 2 shows the frame 3 without the jumping mat 6, without rope rings 5 and without legs 4. From this view it is clear that the frame has a plurality of frame segments 8, 9, 10, 11, 12, 13, i.e. a total of six frame segments. More or fewer frame segments can also be provided. The frame segments 8 - 13 are detachably connected to one another by connecting pieces 14, which is generally considered to be advantageous. For this purpose, the connecting pieces 14 are each inserted into two adjacent frame segments 8 - 13.

The frame 3 is a round frame, i.e. a frame with a round frame shape when viewed from above. The invention is also applicable to polygonal frame shapes.

The frame segments 8 - 13 preferably each have a round outer cross-section. It is understood that the outer cross-section is also considered round if it deviates slightly from the round cross-sectional shape, for example if it has a radially inner circumferential notch.

Figure 3 shows the frame segment 8, a connecting piece 14 and the frame segment 9 in an exploded perspective view. In the description, the

Frame segment 8 as the first frame segment and the Frame segment 9 is considered as the second frame segment. It is understood that the assignment may also be different.

The connecting piece 14 has a first connecting section 15 and a second connecting section 16. The first connecting section 15 and the second connecting section 16 have a web 17. In the present case, the web 17 is continuous, preferably in one piece. It therefore forms the first connecting section 15 and the second connecting section 16. Likewise, two webs 17 can also be formed, each of which functions as the first connecting section 15 and the second connecting section 16. The web 17 preferably has a rectangular cross-section.

The connecting piece 14 has a support device 18 which (in the assembled state; see e.g. Figure 2) extends radially outwards from the frame 3. For this purpose, the support device 18 has a lateral arm with two legs 19 which are preferably welded to the web 17, as indicated by the weld seams 20.

As previously stated, the web 17 is preferably formed in one piece and advantageously extends as a one-piece molded body between the two legs 19. Such a construction is particularly rigid.

As can be seen from Figure 3, the support device 18 has a vertical section 21 which serves to support one leg 4 (see Figure 4), as will be explained in more detail below. The support device

18 is not limited to the specifically shown Construction consisting of arm (with legs 19) and vertical section 21. Importantly, the connecting piece 14 has a lateral component extending outwards from the frame 3 (see Figure 2) so that the legs 4 are arranged outside the frame (in a plan view of the frame).

The web 17 has a top side 22 and a bottom side 23 (see Figure 4). A support web 24 is preferably arranged on the bottom side 23, preferably perpendicular to the web 17. The support web 24 strengthens the overall construction considerably. This is particularly true if the support device 18 has a stop 25 on which the support web 24 is supported. In the embodiment shown, the stop 25 is designed in two parts and is formed by one leg 19 each. It can also be designed in one part.

The connecting piece 14 is preferably made of metal. The support web 24 is advantageously welded to the web 17 at individual welding points 26.

Furthermore, it is considered advantageous if the thickness D and/or the width B of the first connecting section 15 and possibly the second connecting section 16 is/are essentially constant. This makes it possible to create a particularly resilient connection with the first frame segment 8 and possibly the second frame segment 9.

It is within the scope of the inventive concept if the connecting piece 14 is firmly connected to the second frame segment 9, for example glued or welded. Then, to connect the first frame segment 8 to the second frame segment 9, the first connecting section 15 is inserted into the first frame segment 8.

In the illustrated embodiment, the connecting piece 14 is designed as a separate component and has - as previously described - a first connecting section 15 and a second connecting section 16.

The first frame segment 8 has a first receiving section 27. The first connecting section 15 for connecting the first frame segment 8 and the second frame segment 9 is inserted into the first receiving section 27. For this purpose, the first receiving section 27 is preferably profiled on the inside. In the present case, the first receiving section 27 has a guide rail 28 for receiving the web 17. The guide rail 28 preferably has guide ribs 29 which facilitate insertion and rest against the first connecting section 15 when inserted. In principle, it is considered advantageous if, in the assembled state, the first connecting section 15 is supported from above and below in the first receiving section 27. The first receiving section 27 therefore rests against the top side 22 and the bottom side 23.

Advantageously, the guide rail 28 forms a holder 30 for the support web 24. In the assembled state, the holder 30 conveniently rests on both sides of the support web 24.

Figure 4 shows the connecting piece 14 with the first

Frame segment 8 and the second frame segment 9 analogous to Figure 3 in a perspective view from below. From this view it is clear that the support web 24 is arranged perpendicular to the web 17. The support web 24 rests against the stop 25, which is formed by the two legs 19.

It is also clear that the second frame segment 9 is constructed in exactly the same way as the first frame segment 8. For this reason, the same reference numerals are used in part in the following description. The second frame segment 9 has a second receiving section 31. The second connecting section 16 for connecting the first frame segment 8 and the second frame segment 9 is inserted into the second receiving section 31. For this purpose, the second receiving section 31 is preferably profiled on the inside. In the present case, the second receiving section 31 also has a guide rail 28 for receiving the web 17. The guide rail 28 preferably has guide ribs 29 which make insertion easier and rest against the second connecting section 16 when inserted. In principle, it is considered advantageous if, in the assembled state, the second connecting section 16 is supported from above and below in the second receiving section 31. The second receiving section 31 thus rests on the upper side 22 and the lower side 23.

Advantageously, the rail 28 forms a receptacle 30 for the support web 24. In the assembled state, the receptacle 30 conveniently rests on both sides of the support web 24.

Furthermore, the notch 32 already mentioned in Figure 2 can be seen in Figure 4. Figure 5 shows the connecting piece 14 and partially the two frame segments 8, 9 in a top view. This makes it clear that the first frame segment 8 has a first curved longitudinal axis LI with a first radius of curvature RI. The first connecting section 15 has a second longitudinal axis L2 with a second radius of curvature R2. The radii of curvature RI and R2 are the same. In the present case, the connecting piece 14 is formed in one piece and also has a second connecting section 16 which has the second radius of curvature R2. The third radius of curvature R3 of the third longitudinal axis L3 of the second frame segment 9 also corresponds to the second radius of curvature R2.

Figure 6 shows the first frame segment 8 and the second frame segment 9 in an assembled state. In the assembled state, a gap 33 is formed between the first and the second frame segment 8, 9, from which the connecting piece 14 extends radially. In order to cover the gap 33, a housing is provided, which in the present case is formed from a lower housing part 34 and an upper housing part 35. In the assembled state, the connecting piece 14 is partially received in the housing and the upper housing part 35 and the lower housing part 34 are advantageously screwed together by means of a screw 36. The housing can have a cap 37 which covers the gap 33. Alternatively, the upper housing part 35 (without cap) can cover the gap 33. The vertical section 21 is received in the lower housing part 34 and engages in particular in a projection 38 of the lower housing part 34. A folding leg or a rigid leg can be accommodated on the attachment z 38. Figures 7 and 8 show a leg 4 designed as a folding leg. Figure 7 shows the leg 4 as it is initially pulled off the attachment z 38 in the direction of the arrow PI against a spring force. In this position it can be pivoted about an axis 39 and for this purpose has a rod 40 with which the leg 4 is pivotally connected to the attachment z 38. Such folding legs are basically known. In Figure 8 the leg 4 is folded down and received between two lugs 41.

Figure 9 shows a variant of the folding leg according to Figures 7 and 8. Here, the leg 4 is designed as a screw leg. For this purpose, the attachment 38 has an external thread 42 onto which the leg 4 with an internal thread can be screwed.

Figures 10 to 13 show a third embodiment analogous to Figures 3 to 6. For reasons of clarity, the same reference numerals are used in this embodiment as in the previous embodiments, even if the shape differs slightly.

With reference to Figures 10 and 11, in this embodiment the connecting piece 14 has a first connecting section 15 and a second connecting section 16, which are formed by a web 17. When the trampoline frame is aligned as intended, the web 17 extends horizontally, but in contrast to the previous embodiments it is arranged upright, in this case on edge. This means that it is able to absorb high leverage forces.

The support device 18 engages in the intended

Alignment of the trampoline frame (i.e. horizontal Frame) on a vertical broad side 43 of the web 17, which is considered to be particularly advantageous in itself. The support device 18 is preferably welded to the web, in this case via the two legs 19, as can be seen from the weld seam 20. The two legs 19 are formed by a U-profile 44, as can be seen from Figure 11. It can also be seen from this that the support device 18 preferably reaches through the web 17 and is fixed to the web 17 with a weld seam 20.

In the first embodiment, the projection 38 for receiving a leg 4 is formed by the housing base 34, see Figures 6 and 7. In the present embodiment, the projection 38 is welded to the support device 18, which is advantageous in itself. This creates a particularly stable structure.

A significant difference from the first embodiment is that in the first receiving section 27 the guide rail 28 runs upright (Figure 10). The guide rail 28 of the second receiving section 31 also runs upright (Figure 11). It is therefore suitable for receiving the upright web 17. The guide rail preferably has guide ribs 29, as are already known from the first embodiment.

Figure 12 shows a view of the third embodiment analogous to Figure 5, namely a top view. This shows in particular that the radii of curvature RI, R2 and R3 are the same. It is also clear that the first connecting section 15 and the second connecting section 16 are one-piece and are formed in particular by the web 17. can be as advantageous in itself. For the rest, reference is made to the description of the first embodiment.

Figure 13 corresponds to the representation according to Figure 6, whereby in this case the lower housing part 34 is screwed directly to an upper housing part 46. The upper housing part 46 directly overlaps the gap 33. As in the first embodiment, an additional cap 37 is therefore not required (Figure 6). The lower housing part 34 has an opening 45 through which the projection 38 extends.

Figure 14 shows a fourth embodiment. Here, the projection 38 has an external thread 42 so that a rigid screw leg can be screwed on instead of a pivoting folding leg.

If location information such as side, radial, top or bottom is used in the description, these refer to a trampoline or trampoline frame in the assembled position for use, i.e. in the intended orientation of the trampoline frame. In this position, the frame is arranged in a horizontal plane. "Radial" refers to the center of the surrounding frame.

Furthermore, the features described in connection with the first connecting section also apply to the second connecting section, provided that the connecting piece is designed as a separate component. The connecting piece can then be plugged into the first and second frame segments, which is considered advantageous in itself. The same applies to the first and second recording sections .
