[0002] Description [As of December 19, 2022]

[0003] The invention relates to a trampoline with a surrounding frame and with at least one leg which has a tubular section and is pivotally connected to a base of the surrounding frame via a rod received in the leg, wherein the leg has an inner wall and is axially movable relative to the rod against a spring force.

[0004] Such trampolines are known from the prior art. These are, in particular, so-called fitness trampolines, which feature a jumping mat and rubber-elastic rope sections that suspend the jumping mat from a surrounding frame. The rope sections can be ring-shaped or open. It is also known to use steel springs instead of rope sections to connect the jumping mat to the surrounding frame.

[0005] The trampoline's legs ensure that the frame—and thus the jumping mat—is positioned at a certain distance from the ground on which the trampoline is placed. This distance allows the jumping mat to move freely during use without touching the ground during normal operation.

[0006] When a trampoline is not needed, it is often stored away, for example in a corner. With rigid legs, i.e. legs that are rigidly connected to the surrounding frame, the trampoline takes up a certain amount of space. This is why trampolines with folding legs are now being offered. These are legs that can be pivoted relative to the surrounding frame. When the trampoline is not needed, the legs can be folded down. This makes the trampoline narrow, allowing it to be stored away with added space. The invention is directed at such trampolines with folding legs.

[0007] A trampoline with folding legs is known, for example, from WO 2011 / 083093 A1. Each leg has a tube section and a horizontal bar arranged in the tube section, which is pivotally connected to a base. In the known trampoline, the base is detachably connected to the surrounding frame. Trampolines are also known in practice in which the base is welded directly to the frame. When the legs are unfolded for use of the trampoline, the respective leg overlaps the base and is held in an upright position by the base. The leg is held in this position by spring force. To fold the leg down, the leg is pulled away from the base in the axial direction of the leg, against the spring force. It can then be folded down, with the leg being pivoted around the base with the inner bar. Trampolines with folding legs have generally proven themselves.However, it was found that the handling of the folding leg could be improved. In particular, existing designs pose a certain risk of injury due to the sometimes quite strong spring preload. This is also due to the fact that when the leg is unfolded, a gap forms between the base and the leg in which the user can become trapped.

[0008] Based on the known state of the art, the invention is based on the object of improving the handling of folding legs.

[0009] To achieve this object, the trampoline mentioned at the outset is characterized according to the invention in that the rod has a piston which rests against the inner wall.

[0010] The piston on the rod reduces the return speed of the leg, which is particularly important when the leg is placed on the base. The piston is advantageously arranged so that it can move within the leg. During the relative movement between the piston and the leg surrounding the piston, air is displaced. This is because the piston rests against the inner wall. During the relative movement, the piston slides along the inner wall. The resulting air displacement on the one hand and the friction on the other ensure that the return speed of the leg is reduced, although the friction can be kept relatively low depending on the design of the piston. The speed reduction improves handling considerably and at the same time reduces the risk of injury.Unlike the current technology, when the leg is released it can no longer spring back towards the base at high speed, but instead moves back to its starting position at a slower pace.

[0011] The piston can be designed in such a way that when it moves relative to the tube section, air flows past between the inner wall and the piston. It can also be designed in such a way that it seals against the inner wall so that air is displaced during a relative movement. The piston can also be designed in such a way that when the tube section moves relative to the rod in one direction, air is displaced and in the other direction, air flows past between the piston and the inner wall. It should be noted that the above variants are ideal solutions. In practice, depending on the material and tolerances, mixed forms can also occur, for example in the form of predominantly displacement with a proportion of bypass flow or vice versa.

[0012] The piston is preferably coupled to the rod. It therefore moves with the rod, or rather, it remains in position with the rod, while the leg is moved relative to the rod. The movement occurs in the axial direction of the leg. A slight tilt of the leg is possible depending on tolerances.

[0013] The position of the piston is largely freely selectable. However, this requires that the leg has sufficient freedom of movement to be pulled off the base. The piston must be able to slide along the inner wall within this freedom of movement. It has proven particularly advantageous from a design perspective to arrange the piston at a free end of the rod. The free end is the opposite end of the rod from the end that is hinged to the base. The free end therefore expediently projects into the leg. Mounting the rod in the leg is also particularly advantageous if the piston is arranged at the free end of the rod.

[0014] A preferred embodiment is characterized in that the piston is designed as a flexible membrane, which preferably widens in the direction away from the rod and / or can be designed to be flexible. Such pistons are known from bicycle pumps and have the particular advantage that they can be pulled very quickly in one direction. The air then passes from one side of the membrane between the membrane and the inner wall to the other side of the membrane.

[0015] If the piston is moved in the other direction (or the leg is moved in the other direction), the diaphragm seals against the inner wall. This is made possible by the diaphragm widening in the direction away from the rod.

[0016] Preferably, the base has a pivot axis to which the rod is hinged, as will be explained in more detail later. The membrane advantageously opens and / or widens in the direction away from the pivot axis.

[0017] The air is guided out of the leg in one direction through the piston. For this purpose, the leg advantageously has at least one vent opening. The speed of movement can be adjusted depending on the size of the vent opening, whereby the speed of movement also depends on the spring force which preloads the leg into its starting position. In a preferred embodiment, the factors spring force and size of the vent opening therefore determine the return speed of the leg. Advantageously, the flow cross-section of the at least one vent opening is smaller, preferably significantly smaller, than the cross-section of the tube section. The flow cross-section is therefore preferably selected such that the displaced air can only flow out slowly, so that the leg can only move towards the base at a slower speed.

[0018] According to the invention, the leg (fixed to the base) is axially movable relative to the base against a spring force. The leg can therefore be pulled off the base against the spring force. Conversely, the leg (in its folded-out position) is advantageously held on the base by the spring force. Preferably, the rod is arranged within a spiral spring and has a first stop with which the rod is supported on the spiral spring. This results in a compact and easy-to-assemble construction. This applies in particular when the first stop is located directly beneath the piston, as is considered advantageous. The first stop can simultaneously support the aforementioned diaphragm.

[0019] The leg conveniently features a second stop for the coil spring. Thus, when the leg is pulled away from the base, the spring is compressed between the first and second stops. When the leg is released, the spring relaxes again.

[0020] According to the invention, the leg has a tube section. This can be designed, for example, as a metal tube which preferably has a round cross-section. The tube section not only offers the option of receiving the bar and, if necessary, further components such as a spring, but also offers the option of inserting the components into the tube section through one end or both ends of the tube section. To close the leg, it is proposed that the leg expediently has a cover at the end opposite the base. The cover can have a larger diameter than the tube section so that the leg rests on the ground with the cover when the trampoline is in use. The cover is preferably inserted into the leg or the tube section. It is made, for example, of plastic or rubber to provide a non-slip surface.

[0021] As already mentioned above, it is advantageous if air can escape from the leg. At least one vent opening is advantageously used for this purpose. It is considered particularly advantageous if the at least one vent opening is formed between the tube section and the cover. For this purpose, the cover can, for example, form a recess which, together with the leg, forms the at least one vent opening.

[0022] In a further development of the invention it is proposed that the inner wall is formed by a first insert which is inserted into the pipe section. The piston is preferably arranged so as to be movable in the first insert. A construction of this type has considerable advantages. Firstly the insert can be designed as an injection-molded part. This is simple to manufacture. It is also advantageous in terms of manufacture if the insert can be inserted into the pipe section. The insert can have a shoulder which rests on a free end of the pipe section. A precise insertion depth is therefore defined. Furthermore the inner wall of the insert can be easily manufactured with the desired tolerance. This applies in particular when the first insert is made of plastic, which is considered advantageous.

[0023] The first insert preferably has a first end through which the piston is preferably inserted. Alternatively or additionally, the first insert has an opposite second end through which the rod extends. The rod is preferably mounted so as to be longitudinally displaceable at the second end. In this way, the insert can be assigned a number of functions, namely a guiding function for the piston and, advantageously, a centering function for the rod. The mounting of the rod stabilizes the rod when the leg is being handled, which means that the leg is stabilized when it is pivoted.

[0024] Advantageously, the second end forms a second stop against which the coil spring rests. The second stop, together with the coil spring, forms a compact structural unit. Together with the piston, the rod, and the coil spring, a functional unit can be provided that is pre-assembled and inserted into the pipe section.

[0025] In an advantageous embodiment, a second insert is inserted into the tubular section, allowing the leg to be attached to the base. The second insert significantly reinforces the leg and ensures that it does not expand.

[0026] It is understood that the second insert is independent of the first insert, meaning that the first and / or the second insert can be inserted into the tube section. The second insert is preferably made of plastic. The second insert can provide an excellent fit so that the leg sits firmly on the base. Advantageously, the second insert forms a shoulder which rests on one end of the tube section. If the first insert is used in addition to the second insert, the first insert is inserted into a first end of the tube section and the second insert is inserted into a second end of the tube section.

[0027] Preferably, the rod is mounted in the second insert so that it can be moved longitudinally. This provides additional stability when pivoting the leg.

[0028] Additionally, the rod can be mounted in the second insert in a rotationally fixed manner. This means that the leg cannot be rotated once it has been removed from the base, for example, to be folded down. This has the advantage, among other things, that the leg always remains correctly aligned, which can be important, for example, for the engagement of the base with the leg.

[0029] A preferred embodiment is characterized in that the leg is pivotable in a pivot plane and has two lateral guide lugs which, when the leg is unfolded, engage in lateral recesses in the base. 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 second insert described above forms the guide lugs, while the base forms the recesses.

[0030] Additionally or alternatively, it can be provided that the leg is pivotable in a pivot plane and has a projection arranged in the pivot plane which engages in a recess when the leg is in the unfolded state. This central projection also provides additional stability. In particular, however, it is also able to stabilize the folding up and down process of the leg, namely because the base has a free end with a frontal and preferably slit-like opening, and because the projection engages in the opening when the leg is folded down. Preferably, the projection also engages in the slit-like opening during the folding movement. This allows the leg to be guided additionally during the movement, which provides particular stability during movement.

[0031] The invention provides a trampoline which has a high degree of flexibility due to the foldability of the legs. Stability is particularly important when unfolded. But even when folded down, i.e. when the legs are folded in, it is advantageous if the legs remain in the folded position, even when the trampoline is moved, for example, to be stowed away. For this purpose, the base is advantageously formed by a lower part with two centering lugs which grip the leg on both sides when it is folded down. The leg is therefore received between the centering lugs in the folded down state and is expediently clipped between the two centering lugs. The centering lugs are arranged at a distance from the base, which stabilizes the storage of the leg in the folded down state.The invention is explained in more detail below using a preferred embodiment in conjunction with the attached drawing. The drawing shows:

[0040] Figure 10 is a schematic perspective view of the leg of Figure 8 in a partially folded state; and

[0041] Figure 11 is a schematic representation of the leg analogous to Figure 10 in a completely folded state.

[0042] Figure 1 shows a trampoline according to the invention, which has a surrounding frame 1, a plurality of legs 2, and a flexible jumping mat 3. The jumping mat 3 is connected to the frame 1 via elastic cable sections 4 such that it is held elastically within the frame 1. When jumping (or swinging) on ​​the jumping mat 3, the cable sections 4 yield. Such a construction is known in principle.

[0043] The legs 2 are foldable legs, which are unfolded in Figure 1. In this position of the legs 2, the trampoline is in use, meaning it can be used for exercises. Figure 2 shows the trampoline with the legs 2 folded down; for clarity, the jumping mat is not shown. In this position, the trampoline can be stowed away.

[0044] Because the legs 2 are folded down, it is now very narrow, which saves space. The folded legs 2 advantageously point radially inward from the frame 1.

[0045] Figure 3 shows a detail of the surrounding frame 1 with a support device 5. In the use position, the support device 5 extends laterally from the frame 1 and has a first leg 6 that extends downwards (in the use position).

[0046] The support device 5 preferably has a second leg 7, from which the first leg 6 extends. Advantageously, the first leg 6 extends downwards from the second leg 7. The second leg 7 is expediently connected to the frame 1 and extends laterally from the frame 1 when the trampoline is in the use position.

[0047] The trampoline has a base 8, onto which a leg is detachably attached or attachable, as explained in more detail below. The base 8 is made of plastic, for example.

[0048] At this point it should be pointed out that it is not important for the invention where exactly the base 8 is arranged in relation to the frame 1. It can therefore also be arranged in the use position directly underneath the frame 1, i.e. not to the side of the frame 1. It is important that the leg 2 can be plugged onto the base 8, whereby in the use position of the trampoline the respective leg 2 is plugged onto the base 8 and to store the trampoline the leg 2 can be pulled off the base 8 and folded down.

[0049] In the assembled state, the support device 5 is connected to the base 8. Preferably, the leg 6 engages with the base 8. This advantageously creates a form-fitting, stable connection.

[0050] So that the leg 6 can engage with the base 8, the base preferably has a receptacle 9. The receptacle 9 is advantageously designed such that the leg 6 is received in the receptacle 9 in a form-fitting manner.

[0051] The base 8 is advantageously formed by a lower part 10. The lower part 10 has a recess 11 in which the surrounding frame 1 is received. Together with an upper part 12, the lower part 10 forms a housing in which the support device 5 (in the assembled state) is received.

[0052] In the present embodiment, the lower part 10 and the upper part 12 are screwed together. For this purpose, the lower part 10 has a threaded projection 13 that extends through an opening 14 in the support device 5. The lower part 10 and the upper part 12 are screwed together by means of a screw 15 that extends through the threaded projection 13. The engagement of the threaded projection 13 through the opening 14 in the support device 5 imparts particularly good stability to the connection between the housing and the support device 5.

[0053] The reference number 16 designates a cap which, in the assembled state, is arranged on the upper part 12, in particular is clipped onto the upper part 12. The cap 16 overlaps the surrounding frame 1 and has a

[0054] Recess 17 in which the frame 1 is accommodated.

[0055] As previously described, the base 8 is designed to accommodate one leg 2 (Figure 2). The leg 2 is pivotally connected to the base about a pivot axis 18. In the illustrated embodiment, the pivot axis 18 is supported on the base 8 and is, for example, glued or pressed into an opening 19. It passes through an axis opening 20 of the first leg 6.

[0056] In the exemplary embodiment according to the invention, the legs 2 are designed to be pivotable about the pivot axis 18, as shown, for example, in Figure 2. As is also evident from Figure 2, the leg 2 is received between two centering lugs 21 in the folded state. Figure 4 clearly shows that the centering lugs 21 are attached to the housing, in particular to the lower part 10. This allows the centering lugs 21 to be made of a different material than the housing or the lower part 10. A different material can, for example, be more grippy than the material of the housing, so that the legs 2 are held particularly well in the folded state.

[0057] Figure 4 shows the components of a leg 2 in an exploded view, from which the individual components of the leg 2 can be seen. The leg 2 has an elongated tubular section 22, which is preferably designed as a hollow cylinder. The reference number 23 designates a first insert which is inserted into a first end 24 of the tubular section 22. The first insert 23 has a shoulder 25 with which the first insert 23 is supported on the tubular section 22. The shoulder 25 acts as a stop and limits the insertion depth of the first insert 23 into the tubular section 22. The first insert 23 has an inner wall 26 which is preferably cylindrical.

[0058] The tubular section 22 has a second end 27 into which a second insert 28 is inserted. The second insert 28 has a shoulder 29 that limits the insertion depth of the second insert 28. The second insert 28 preferably also has a guide 30 for a rod 31, which is guided in the guide 30 so as to be longitudinally displaceable and preferably also rotationally fixed.

[0059] The leg 2 can be attached to the base 8 using the second insert 28. In this case, the second insert 28 advantageously overlaps the base 8, as will be described in more detail in connection with Figure 6.

[0060] The second insert 28 has two lateral guide lugs 32 which, when the leg is unfolded, engage in lateral recesses 33 of the base 8. The second insert 28 further has a projection 34 which cooperates with a recess 35 formed in the base 8. The projection 35 engages in an opening 36 of the base 8 when the leg 2 is unfolded.

[0061] The rod 31 is the connecting link between the leg 2 and the base 8 and thus the surrounding frame 1. For this purpose, the rod 31 has a pivot opening 37, with which the leg 2 is pivotally connected to the base 8. The pivot axis 18 advantageously extends through the opening 19 and the pivot opening 37. The rod 31 is preferably pivotable in the opening 36. The opening 36 allows the rod 31 to be pivoted relative to the base 8. For this purpose, it is preferably designed like a slot, wherein it preferably opens radially inwards.

[0062] At the end of the rod 31 opposite the pivot opening 37 there is arranged a piston which in the present case is designed as a membrane 38 which is expediently concave and preferably widens outwards from the rod 31. The rod 31 is arranged within a spiral spring 39 which is supported on a first stop 40 of the rod. The first insert 23 forms a second stop 41 (see also Figure 6), the spiral spring also being supported on the second stop 41 in the assembled state. The leg 2 can therefore be withdrawn from the base 8 against a spring force of the spiral spring 39 and is held on the base 8 by the spring force.

[0063] The membrane 38 rests against the inner wall 26. In one direction of movement, the membrane 38 seals against the inner wall 26. This is expediently the direction of movement of the leg 2 toward the base 8. In the other direction of movement, the membrane 38 allows air to pass between itself and the inner wall 26. In the retraction direction of the leg 2, the air resistance is therefore advantageously lower.

[0064] The reference numeral 42 designates a cover which is inserted into the front of the leg 2, more precisely into the first insert 23. It can be made of rubber or plastic. In the direction in which the leg 2 is inserted, the air must escape from the leg 2, in this case from the first insert 23. For this purpose, at least one vent opening 43 is formed in the cover 42. To protect the internal components of the leg 2, a third insert 44 is provided which is arranged in the first insert 23 between the membrane 38 and the cover 42.

[0065] Figure 5 shows the leg construction according to the invention in an assembled state, wherein the tubular section 22 is shown in dashed lines so that the internal components are visible. The leg 2 is in a state in which it has been pulled away from the base 8. In this state, the rod 31 is visible between the second insert 28 and the base 8. The coil spring 39 is advantageously accommodated in the first insert 23 (see Figure 6), so that the leg 2 is pulled away from the base 8 against the spring force, which is considered advantageous. Furthermore, it can be seen from Figure 5 that the leg 2 is hinged to the base via the rod 31. The opening 36 is designed such that the rod 31 can be pivoted about the pivot axis 18 (see Figure 4), wherein the opening 19 into which the pivot axis 18 is inserted can be seen in Figure 5.Finally, Figure 5 clearly shows that the first insert 23 is inserted into the first end 24 and the second insert 28 is inserted into the second end 27 of the tube section 22. The first end 24 is the free end of the leg 2, with which the trampoline rests on a surface. In Figure 5, the leg construction is shown the other way around, i.e., with the frame 1 lying on a surface and the legs 2 pointing upwards. In this position, the legs 2 can be easily folded up and down.

[0066] Figure 6 shows the leg construction according to the invention in an unfolded state. In this state, the trampoline can be used for exercises. As a rule, the frame 1 is then aligned horizontally, although it should be noted that in some designs, there are also positions in which the frame 1 can be slightly tilted.

[0067] The second insert 28 is placed on the base 8. The rod 31 is pivotally connected to the base 8. The first insert 23 is inserted into the tubular section 22 and rests against the tubular section 22 with the shoulder 25. The coil spring 39 is arranged between the first stop 40 and the second stop 41 (which in this case is the bottom of the first insert 23). This pulls the leg 2 toward the base 8.

[0068] The membrane 38 rests against the inner wall 26 of the first insert 23. The invention generally provides for the piston (which is designed here as a membrane 38) to rest against the inner wall 26. Therefore, if no first insert 23 is provided, the piston can be supported against the inner wall 26 of the tube section 22.

[0069] The leg 2 can be moved against the force of the coil spring 39 in the direction of an arrow 45. This pulls the leg 2 away from the base 8. In the present exemplary embodiment, the second insert 28 moves out of engagement with the base 8. During this movement, air flows between the inner wall 26 and the membrane 38. In the other direction, i.e. in the direction opposite to the arrow 45, the leg 2 moves onto the base 8. In this case, air is displaced by the membrane 38 and flows out of the leg 2 through the at least one vent opening 43 (see Figure 4). This slows down the return movement of the leg 2. Figure 7 shows the leg 2 in a folded state. In this state, the trampoline can be stowed away to save space. The leg 2 is pivoted about the pivot axis 18 and is held between the two centering lugs 21 (see Figure 6).

[0070] As can be seen particularly well in this view, the spiral spring 39 is compressed between the first stop 40 and the second stop 41.

[0071] Figures 8, 9, 10, and 11 show a sequence of movements in which leg 2 is moved from an open position (Figure 8) to a folded position (Figure 11). For clarity, the trampoline is shown only in section and upside down, i.e., with the legs 2 pointing upwards.

[0072] In Figure 8, leg 2 is in the unfolded position. In this leg position, the trampoline can be used for trampoline exercises.

[0073] In Figure 9, the leg 2 is removed from the base 8. In this leg position, the rod 31 is visible, by means of which the leg 2 is pivotally connected to the base 8.

[0074] In Figure 10, the leg 2 is partially folded down, wherein the leg 2 is pivoted in a pivot plane, as indicated by the arrow 46. From this illustration, it can be seen that the leg 2 has a projection 34 arranged in the pivot plane, which projection 34 engages in a recess 35 of the base 8 when folded up. The leg 2 also has two lateral guide lugs 32 which, when folded up, engage in a form-fitting manner in lateral recesses 33 of the base 8.

[0075] In Figure 11, the leg 2 is completely folded down and received between the two centering lugs 21. In this position, the projection 34 advantageously engages the opening 36.
