description

The invention relates to a trampoline, comprising a frame, a plurality of nozzles arranged on the frame, and a plurality of legs for supporting the frame on the floor.

The invention is particularly directed to so-called mini trampolines. These are smaller trampolines with a maximum diameter of 2 to 3 meters, which are used in physiotherapy and fitness.

In the so-called mini-trampolines one distinguishes between trampolines with a spring suspension and a rubber cable suspension. When the spring suspension is

Jumping towel attached to the frame via coil springs. For this purpose, the jumping cloth as a receiving device, for example, a bracket or an eyelet, which is attached by means of a loop on the jump cloth and in each one

Spiral spring engages. On her other side is the

Spiral spring suspended in the frame. A trampoline with one Spring suspension provides significant acceleration forces.

The rubber rope suspension uses one or more elastic rope rings or (open) ropes that connect the ski mat to the frame. Here, the receiving device may be formed as a hook element, in each one

Suspension is hung. Alternatively, a loop is considered, through which a rope is pulled, which connects the jumping cloth to the frame. The greater elasticity of such a rubber cable suspension ensures a "softer" braking of the body and so far not only protects the

Joints, but also prolongs the muscular loading ^¬ and relief phases in jumping, which is advantageous

Training effects brings.

The invention is directed both to trampolines with spring suspensions and 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 trampolines, regardless of the type of

Suspension of the jump cloth and the geometry of the frame.

The well-known trampolines have in common that they have a (often round) frame, are arranged on the neck. The sockets are usually attached to the frame

welded and each serve to receive a leg which can be screwed, for example, in the socket.

Both straight legs and folding legs are known from the prior art. The straight rigid legs sit rigidly in or on the neck and can be detached from or from the neck - for example, unscrewed - when the trampoline is to be disassembled. Alternatively, the folding legs are used. These are also fixable in the neck, but in contrast to the rigid legs

hinged, so that the trampoline can be stowed relatively easily to save space.

Both trampoline types have proven themselves in practice. However, the aim is to reduce both the production costs and the storage costs.

Based on the known prior art is the

Invention the object of the invention to provide a trampoline, which allows a more cost-effective production. To solve this problem, the aforementioned trampoline according to the invention is characterized in that in each case an insert is received in the neck, on each of which a leg is fixed. The trampoline according to the invention opens up completely new possibilities in production and logistics. For the first time, it is possible to provide a basic construction that allows the production of both a rigid-legged trampoline and a fold-down trampoline. This basic construction according to the invention comprises the frame and the nozzle. Depending on which leg construction is to be used, the corresponding insert is selected. As a result, the invention provides a much more flexible

Production of the final product and a significant reduction of storage costs.

From the practice known nozzles have a thread in / on which the respective leg is screwed on or. In According to a further development of the invention, the nozzle has at least partially a cylindrical inner surface, which preferably cooperates with the insert, in particular when the insert has a cylindrical base, with which the

Insert is inserted into the socket. The cylindrical inner surface of the nozzle brings manufacturing technology and thus also cost advantages. In addition, the use of the invention in a cylindrical inner surface is not only good grip, which is a prerequisite for the stability of the construction, but is also easy to use. For this purpose, the inner surface expediently cooperates with the nozzle. This is true even if the inner surface is not completely cylindrical, but partially cylindrical

is formed, wherein the part-cylindrical surfaces (the insert and the nozzle) extend in the axial direction.

As indicated above, it is essential for the durability of the trampoline that the insert is firmly received in the neck. In fact, when using the trampoline, considerable forces are generated, not just vertical ones

Forces, but (depending on exercise on the trampoline) too

lateral forces that exert a bending moment on the legs - and thus the use -. Against this background, it is considered advantageous if the nozzle and the insert are each connected to one another in a non-positive and / or materially bonded manner. First and foremost, it is possible to bond the insert in the nozzle. Additionally or alternatively, the

Insert be pressed into the socket. The compression can also be achieved by a shrinkage or partial deformation of the nozzle. Both the bonding and the pressing have the advantage of a large-area connection, which has a positive effect on durability. Additionally or alternatively, a positive fixing of the insert in the nozzle conceivable. Here is an example of a bayonet connection

called. An anti-rotation device, as will be explained below as an advantageous development, can be a

create a positive connection.

The construction of the invention should be with only one

Basic frame allow the production of trampolines with both rigid and fold-down legs.

Especially with hinged legs is a correct

Aspiration of the respective pop leg desirable so that the folded legs show as evenly as possible in the middle of the trampoline.

Advantageously, the nozzle and / or insert on a first rotation. This can be a

Act inside profile of the nozzle, which cooperates with a corresponding outer profile of the insert. As special

advantageous, it is considered when the nozzle a

Has recess in which engages the insert. The insert preferably has a nose which engages in the recess. The anti-rotation allows always the same orientation of the insert and thus the respective leg with respect to the frame. As rotation in the sense of the invention but can also be understood an alignment aid for use. The alignment aid is preferably designed as a marking, which is arranged on or on the insert. The mark

advantageously allows the insert to be aligned with respect to the base frame, and is formed, for example, as an arrow symbol. It is understood that other symbols may also be considered. In an essential embodiment of the invention

suggested that the insert is made of a different material than the nozzle. In the prior art exist

Trampolines often made of a tubular steel frame construction, to which steel sockets are welded. Inserts made of a different material, in particular of a plastic or a non-ferrous metal, have the advantage of extending the

Life of the trampoline. Investigations have shown that with frequent use of known trampolines the danger

exists that abraded due to the relative movement between the leg and the neck after a certain time in the thread or folding leg of the corrosion protection and the

Steel material is exposed. This makes the legs susceptible to corrosion. In practice, cases have occurred in which rusted leg threads due to corrosion could not be partially unscrewed or turned off. Inserts from another (not susceptible to corrosion)

Material prevents abrasive contact between the leg and the neck, significantly increasing the life.

In addition, it has been shown that during the

Lifetime of a trampoline to develop sounds that

Among other things, be attributed to the growing play between the leg and the frame. In this respect too, the insert according to the invention ensures that the leg does not come into direct contact with the neck. Before this

Background, it is considered advantageous if the

Insert is designed so that it is arranged between the leg and the neck. Preferably, the insert has a shoulder, with which it rests on the neck. On this shoulder expediently the mounted leg comes to rest. For example, the insert may consist of aluminum, in particular high-strength aluminum, or a plastic.

Both materials have sufficient durability and resilience. In particular, plastic is beyond - easily produced, for example by injection molding.

Advantageously, the insert has an internal thread. The leg can be screwed into the thread. The leg may be formed in one piece. Alternatively, the leg has an elongated leg portion and a

Leg insert, wherein the leg insert is received in the leg portion. The leg insert may be formed of the same or different material as the insert (of the

Neck). The leg insert allows a particularly flexible production of the leg. Namely, the leg insert allows a uniform elongate leg portion to be used for both rigid and flip legs. For example, For example, the elongated leg portion includes a tube that may be made of steel or aluminum, for example. To the respective adaptation of the leg section

(Screw leg / folding leg) is simply chosen the appropriate leg insert. This creates over the already mentioned

Flexibility in manufacturing a particularly favorable

Warehousing.

For the rigid legs, it is beneficial if the first

Leg insert has an external thread. The external thread cooperates expediently with the Innengwinde of the insert (the nozzle).

The attachment of the first leg insert in the

Elongated leg section comes in two ways special importance. On the one hand, not insignificant torques occur when screwing the leg into the insert. On the other hand, the construction is as before

executed exposed in use considerable forces. In that regard, it is considered advantageous if the

Leg insert and the elongated leg portion are material and / or non-positively connected. In particular, the leg insert can be glued into the leg section and / or

be pressed.

In addition, the elongated leg portion and / or the leg insert may have an anti-rotation device. The

Anti-rotation is preferably formed as a recess in the elongated leg portion, in which the

Leg insert intervenes. For this purpose, the leg insert preferably has a nose which engages in the recess.

In the case of folding legs, the anti-rotation device serves to align the folding legs, as will be explained in more detail below. In particular, the insert can also have an anti-twist device. In this context, it has already been stated above that the rotation also as

Positioning aid can be designed. Alternatively or additionally, the rotation provides a positive engagement with the nozzle.

In order to absorb the forces when using the trampoline, it is advantageously provided that the

Leg insert at least 1 cm, preferably at least 2 cm, in particular at least 3 cm in the elongated

Strokes leg section. In addition, it is considered advantageous if the leg insert has a cylindrical outer surface. This measure ensures a maximum Contact surface with the also preferably cylindrical inner surface of the elongated leg portion, so that an advantageous load-bearing connection is created. Preferably, the elongate leg portion and the leg insert are made of different materials. In particular, it can be provided that the elongated leg portion is made of steel or aluminum and the leg insert preferably consists of a non-ferrous metal or plastic. Incidentally, it is also conceivable that the leg insert and the elongated leg portion made of the same material, preferably made of aluminum.

With the invention it is advantageously possible to provide trampolines both with rigid screw legs as well as with folding legs available.

An advantageous embodiment of the invention is characterized in that the insert has an approach to which the leg is releasably attachable. The leg can therefore be attached to the insert and removed again. This embodiment is particularly advantageous in folding legs, as will be explained in more detail below. Preferably, the approach of the insert is formed substantially cylindrical. Such a geometry provides a maximum contact surface for the elongate leg portion or its leg insert. With the wording "substantially cylindrical" should be considered that the approach, for example, wells for a pivot axis and / or

Recesses for the pivoting of the leg and / or grooves for any O-rings, the cylindricity

interrupt. The latter can be provided to the Absorbing leg section (in which case the O-ring is compressed) and to secure against loosening of the approach. When folding legs, as will be explained in more detail below, the O-rings also have the task of sliding the elongated leg section

improve .

In an essential embodiment of the invention

proposed that the elongated leg portion is mounted longitudinally displaceable on a receiving device. In this way, the leg portion can be placed on the receiving device and deducted from it - at least partially. The receiving device is preferably pivotable with the

Use connected. For this purpose, the insert has a pivot axis. Advantageously, it can be provided that the

Leg section over the pivot axis out on the insert is pluggable.

Advantageously, the outer diameter of the

Receiving device substantially the outer diameter of the neck. These are each one

The preferred embodiment described above

concerns a trampoline with folding legs. To fold down

Legs are each deducted from the insert legs, thereby exposing the pivot axis. Then the legs can be folded down to the middle of the trampoline. Through the folding legs, the trampoline can be stored to save space.

To unfold the folding legs, the legs in one

upright position worked. It may be advantageous if the insert and / or the receiving device a

Stop for limiting the pivoting movement of

Have recording device. Due to the stop it is ensured that the receiving device and the approach are aligned and aligned, so that it does not lead to tilting and thereby unintentional damage to the corresponding components when attaching the elongated leg portion on the neck.

In order to avoid that the elongated leg portion unintentionally detached from the frame, is in development of the

Invention proposed that the elongated leg portion is biased towards the receiving device. The bias is preferably provided by a tensioning device disposed in the elongated leg portion and preferably in the receiving device

is mounted. The tensioning device may be a spring. As an advantage, however, is a

considered elastic rope, which is as such lighter and cheaper and moreover in use causes less noise. The last point is

especially in a therapeutic use of the trampoline of considerable importance, since noises during use of the trampoline distract and thus have a negative impact on the treatment goal.

The tensioning device is preferably a cable ring

educated. The clamping device may advantageously be suspended in a hook of the receiving device, preferably with bias.

Preferably, the elongated leg portion has an end cap in which the tensioning device is mounted. The cap can have two functions. On the one hand it provides the completion of the leg. Possibly. is placed over the free end of the leg still a rubber buffer. On the other hand, it forms an abutment for the

Clamping device. An advantageous embodiment of the invention is characterized in that the elongated leg portion has a second leg insert, the end at least

partially inserted into the leg section. The second leg insert greatly reinforces the elongate leg portion. At the same time, the second one improves

Leg insert the fit and reduces the

Corrosion susceptibility, as already stated above. Preferably, the leg insert has a shoulder that the insertion depth of the leg insert in the elongated

Wear comes. Appropriately, the cylindrical receptacle of the leg is inserted with attached elongated

Leg portion on the second insert and extends beyond the pivot axis. This ensures that the receiving device can not break during operation relative to the second insert. In the following, the invention is based on preferred

Trampoline. The trampoline has a frame 1, which is only partially shown in the drawing. Circular round or angular, for example rectangular, square or triangular frame shapes are known in practice.

To the frame 1, a plurality of nozzles are attached, for example, welded, of which a nozzle. 2 is shown. The nozzle 2 has a cylindrical

Outer surface 3 and a cylindrical inner surface 4.

According to the invention an insert 5 is provided, which in the

Stub is pressed, shrunk and / or glued. To limit the insertion depth of the insert 5 in the nozzle 2 and to cover the end face 6 of the nozzle, the insert 2 has a shoulder 7, with which the nozzle extends over the end face 6.

The insert 5 is for a screw leg (see FIG. 2).

intended. For this purpose, the insert 5 has an internal thread 8 into which the leg can be screwed. Furthermore, the

Neck 2 has a recess 9 into which the insert 5 engages with a nose 10. The recess 9 creates a

Anti-rotation and prevents the insert 5 rotates in the nozzle 2 when the leg in the insert

is screwed in. In addition, the recess 9 creates a clear alignment of the insert 5 in the nozzle 2. This is especially true for other uses (for example, folding legs), in which the orientation plays an essential role.

Figure 2 shows the embodiment of Figure 1, but now with a leg. The leg has an elongated

Leg portion 11 and a first leg insert 12, which is inserted into the leg portion 11 and fixed there for example by gluing and / or pressing. The elongated leg portion 11 has a recess 13 which has a

Provides anti-twist protection. The first leg insert 12 has a nose 14 with which the leg insert 12 engages in the recess 13. The elongated leg portion 11 is advantageously formed as a pipe section with a preferably round cross-section. In adaptation thereto, the insert 12 has a cylindrical receiving portion 15, with which the insert is inserted into the leg portion 11. The receiving portion 15 extends at least 1 cm, preferably at least 2 cm, in particular at least 3 cm in the elongated

Leg portion 11 in to provide the required stability. To limit the insertion depth and to cover the end faces of the leg portion 11, the insert has a shoulder 16, at the end a

interacts. FIG. 3 shows the leg mounted on the frame 1. As can be clearly seen, the shoulders 7, 16, the neck 2 and the leg portion 11 have the same outer diameter. As can also be seen, the leg portion 11 and the neck 2 through the two inserts 5, 12 from each other

separated. As a result, in particular when the nozzle 2 and the leg portion 11 are made of steel, the

Corrosion susceptibility minimized.

Figure 4 shows a second embodiment, which has the same frame 1 and 2 as the first

Embodiment. It differs from the first embodiment in the specific embodiment of the insert 18, which is designed for folding legs, as will be explained in more detail below. The insert 18 has - as the insert 5 (see Figure 1) - a cylindrical base 19 which is inserted into the socket 2 and fixed there, the insert 18 further has a shoulder 20 which is for resting on the end face 6 of Stutzens 2 comes and covers these when the insert 18 is inserted. With the reference sign 21 a nose is marked, which cooperates with the recess 9. The recess 9 and / or the nose 21 form an anti-rotation for the insert 18, which is particularly important in the present folding leg of high importance. At this point it should be pointed out that the term anti-rotation device for folding legs also means a position aid which has a - twisted - misalignment of the

Use prevented.

Reference is made to Figure 5 which shows the insert 18 in the installed condition. In this case, the nose 21 engages in the recess 9, so that the insert 18 is uniquely positioned in the neck 2. This unique positioning is of considerable importance for the alignment of the

Folding legs, as explained in more detail below.

The insert 18 has a pivot axis 22 which passes through the insert 18. The insert 18 also has a recess 23 in which a receiving device 24 is pivotally mounted about the pivot axis 22. In the assembled state, the pivot axis 22 passes through an opening 25 of the receiving device 24. The receiving device 24 has a pivot projection 26 which comprises two parallel side walls 27, with which the

Receiving device 24 is guided in the recess 23.

End side, a stop 28 is provided, which is the

Pivoting movement of the receiving device 24 limited in the upright position.

Figure 6 shows how the receiving device 24 and the insert 18 are pivotally connected together. The Receiving device 24 is shown in an upright position. In this position, the receiving device 24 and the insert 18 can receive an elongated leg portion 29.

The elongate leg portion 29 may have a second

Leg insert 30 have, for example, made of plastic or aluminum. The second leg insert 30 serves to reinforce the elongated leg portion and has a preferably cylindrical portion 31, with which the

Leg insert 30 is inserted into the leg section 29.

Advantageously, the second leg insert 30 is sleeve-shaped. He expediently has a cylindrical receptacle 32. The elongate leg portion 29 and the second leg insert 30 are connected via a recess 33 and a nose 34 against rotation. The second leg insert 30 is preferably glued and / or pressed into the leg portion 29.

The receiving device 24 is shown in Figure 6 in the upright position. In this, the elongated

Leg portion 29 are inserted with its second leg insert 30 on the receiving device 24. For this purpose, the

Receiving device 24 a Aufnahmeansat z 35 which preferably carries at least one O-ring 36, which as

Anti-slip device for the attached leg is used.

Advantageously, the insert approach 37 and the

Aufnahmeansat z 35 substantially the same outer diameter. Possibly. the outer diameter of the insertion lug 37 may be formed slightly larger than the diameter of the Aufnahmeansat ZES 35, due to the at least one O-ring 36. Under the outer diameter of the diameter is understood that for abutment with the elongated leg portion 29 and whose leg insert 30 is coming. These The definition satisfies the fact that, in particular, the insert lug 37 does not have a fully circumferential cylindrical outer surface, since the outer surface is interrupted by the recess 23 (see FIG. 5).

The receiving device 24 also has a

preferably end hook 38, which serves to receive a trained example as a cable ring 39 clamping device, as will be explained in more detail in connection with Figure 7.

Reference is made to Figure 7, which shows all components of an embodiment of a pop leg. In the hook 38 of the cable ring 39 is mounted and guided within the elongated leg portion to the other end, where he is in turn hooked into the hook 40 of an end cap 41. Instead of the cable ring, a cable section with end-side eyelets or a spring can be used. An elastic rope (possibly with a textile coating) is considered to be preferable to a metal spring in terms of noise in jumping. The cable ring 39 is received with bias in the leg portion 29. This means that the end cap 41 in the direction of the

Leg portion 29 and the leg portion 29 are biased toward the insert 18. However, it is possible to pull the leg portion 29 off the insert 18 to fold over the leg. This condition is shown in FIG.

Referring to Figure 8, the elongate leg portion 29 and the second leg insert 30 are shown partially cut away for ease of understanding. Should that

Folding leg are folded down, this can be deducted from the insert 18, the elongated leg portion 29. In the the leg portion 29 located) O-rings 36 prevent sliding back of the leg portion 29 on the insert 18th

FIG. 9 shows that for unfolding the legs of the

elongated leg section 29 unfolded and on the

Insert 18 is inserted. Here, the shoulder 20 serves to support the elongated leg portion or its insert 30.
