description

The invention relates to a trampoline comprising a frame comprising a peripheral frame and a plurality of legs, a jumping sheet elastically suspended on the frame, at least one guide fixed to the frame and a height adjustable rod is included in the leadership.

The invention is particularly directed to so-called mini-trampolines, which are also called fitness trampolines.

These are smaller trampolines with a maximum diameter of 2 to 3 meters, which are in the

Physiotherapy and use in the fitness area.

In the so-called mini or fitness trampolines

one distinguishes between trampolines with one

Spring suspension and a rubber cable suspension. In the

Spring suspension, the jump sheet is attached to the frame via coil springs. For this purpose, the jump sheet as

Receiving device, for example, a bracket or an eyelet, which is attached by means of a loop on the jump cloth is and m each engages a coil spring. On its other side, the coil spring is hung in the frame. A trampoline with a spring suspension provides considerable 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 frame, depart from the legs. The legs ensure that the frame is at a certain distance from the ground when the trampoline is in place. This ensures that the jumping sheet can move in the direction of the ground when jumping. From practice, both round and polygonal frame shapes are known. The frame consists of a tube that is bent to make the frame. More recently, a fitness trend has been observed in which special exercise programs are tuned to the trampoline. For a secure grip on the trampoline, the support rod is used, the support rod usually has at its free end laterally from the support rod outgoing handles on which the user during the

Can hold exercises.

From DE 20 2014 007 636 Ul a trampoline is known in which the holding rod is attached via an intermediate piece on one leg of the trampoline. In addition, the support bar is secured by two lateral struts which connect the lower end of the support bar with the adjacent legs of the trampoline. The known construction is stable. However, it requires a high cost of materials. In addition, the

Assembly elaborate.

From practice a trampoline is known, on whose frame a clamping device is welded. The support rod is received in the clamping device longitudinally displaceable and lockable. The well-known trampoline is simple and composable. In practice, however, it was found that the life leaves much to be desired.

The invention has for its object to provide a trampoline with rod whose assembly is both easy and on the other hand withstand higher loads. This problem is solved by a trampoline, with a

A frame comprising a peripheral frame and a plurality of legs extending from the frame, a jumping sheet elastically suspended on the frame, at least one guide fixed to the frame, a rod receiving height adjustment in the guide is, and an inner piece which is movably received in the guide, wherein by a relative movement between the inner piece and the guide, the rod is fixed.

The invention allows a fixation of the rod in the

Guidance that withstands high loads during intensive use of the trampoline. It does that

Inside piece the clamping force available. Preferably, the rod is clamped between the guide and the inner piece.

The leadership in the context of the invention to two tasks. First, she picks up the pole and fixes it. Second, it advantageously forms a receptacle for the inner piece.

In the context of the invention, a rod can be used, which has a free end. The free end carries

For example, a handle device or a holder for devices. Then you will only provide a guide for the rod. Alternatively, a rod can be used, which is bent in a U-shape. It has two free ends, one end of each of which can be inserted into a guide. Then one will preferably provide two guides for the rod. In the following description will be off

For reasons of clarity, a frame with only one guide described. Advantageously, the guide has at least one first opening through which the rod is inserted. The opening is appropriate to the outer contour of the rod

adapted, but designed to be larger than the outer contour of the rod so that the rod can be easily inserted into the guide and adjusted in height. Preferably, two openings are provided in the guide. This leads to a more stable guidance of the rod. The two openings are (with the trampoline installed) at the top and bottom of the guide

educated. They cussed appropriately.

In a further development of the invention it is proposed that the guide is designed as a pipe section. Preferably, the guide has a circumferential circumferential wall. The pipe section is a particularly stable and at the same time easy to manufacture embodiment of the guide. The cross section of the pipe section may be round or angular, in particular circular or square. Also come oval or rectangular

Cross-sectional areas into consideration. In the context of the invention, the circular cross section is particularly advantageous

On the one hand for manufacturing reasons and on the other hand for safety reasons, because the round shape in the present application has a lower risk of injury.

The first opening is preferably formed in the peripheral wall. If the pipe section is arranged horizontally perpendicular to the axial extent of the legs, that is to say in the case of a standing trampoline, the opening is arranged at the top, it being said that it is advantageous if a further opening is formed on the underside of the pipe section. The rod then passes through the upper and lower openings of the Guide / pipe section. The upper and lower openings are preferably aligned.

It has already been stated above that the inner piece is movably arranged in the guide. Preferably, the outer contour of the inner piece is adapted to the inner contour of the guide. In a pipe section with a cylindrical

Inner surface, it is thus advantageous if the inner piece has a cylindrical outer surface. The outer surface has a slightly smaller diameter than the inner diameter of the guide, so that the inner piece in the guide is easy to move, which simplifies a fixation of the rod in the guide.

It is considered advantageous if the inner piece has an opening through which the rod passes. The

Opening can be drilled. She goes in case of one

Cylinder piece across the cylinder piece.

Preferably, the inner piece in the guide so

be aligned so that the openings of the guide and the opening of the inner piece are aligned. The openings of the

The inner piece and the guide need not necessarily be the same size. However, they are at least as large as the outer diameter of the rod.

In this context, it should be noted that the above has been spoken of the embodiment of a cylindrical inner piece. The opening for the bar breaks through the

Cylindrical shape. Nevertheless, it is in the sense of

Invention around a cylindrical shape (with an opening).

In addition to a high requirement for the stability of the trampoline, it is also required that, from the user's perspective, the assembly, the attachment of the rod to the trampoline and possibly the maintenance is easily possible. In this context, it is proposed that the guide has a third opening through which the inner piece can be inserted into the guide. For a piece of pipe you will provide the insertion on the front page. A preferred embodiment is characterized in that the insertion direction perpendicular to the two openings in the peripheral surface of the guide

runs. It is also considered preferable if the insertion opening is arranged radially inward. The inner piece is advantageous from the inside out into the guide

plugged in .

Preferably, the diameter of the opening corresponds to the

Inner diameter of the guide. The inner piece can therefore be easily inserted into the guide. There, the inner piece is advantageously slidably received.

To move the inner piece is advantageous a

Actuator provided. Preferably, the inner piece is actuated by an actuating device. The invention thus provides a clamping device for the rod, which consists only of three basic components and compared to conventional solutions provides a much better and more stable clamping. The clamping device is formed from guide, inner piece and actuator.

A particularly advantageous embodiment of the invention is characterized in that the actuating device is supported on the frame or preferably on the guide. Such a construction creates a compact

Overall construction, which is also able to apply large clamping forces on the rod. Preferably the guide has an end wall on which the

Actuator supported.

To apply the clamping forces, it is proposed that the actuating device and the inner piece are threadedly engaged. By turning the actuator, the inner piece is moved in the guide. In this case, the rod is advantageously fixed between the guide and the inner piece, as it is generally considered advantageous.

When turning the actuator two movement models are generally conceivable. Either the inner piece moves away from the actuator when the

Actuator is rotated, or it moves towards the actuator out.

The threaded engagement can be realized in that the actuating device has a threaded pin which engages in a thread of the inner piece. In the

Actuator is, for example, a hand screw, a handle, for example

Plastic and said threaded pin has. The thread is preferably formed on the front side in the inner piece.

Alternatively, the inner piece has a threaded pin which engages in a thread of the actuating device. The actuator can also be a handle here

(For example, on plastic), wherein in the

Handle a mother is added.

In the two embodiments described above, the actuating device has handles which are for To induce the movement of the inner piece to be turned.

Alternatively, the actuating device is designed as a tension lever whose pivoting causes the inner piece to move in the direction of the lever. The clamping lever may analogously to the handle have a thread or a threaded pin, which cooperates with the inner piece. About the

Thread is a default made. To apply the final clamping force of the clamping lever is pivoted. The mechanics of clamping levers is known as such. The voltage is applied via an eccentric of the clamping lever.

The trampoline according to the invention can be used in private households, but especially in fitness studios. In fitness studios the trampolines according to the invention are frequently used in groups. This means that the trampolines must be stowed after their use. In this connection, it is proposed that the actuating device has a lever with which the actuating device is rotatable, wherein the lever in the actuating device

is mounted longitudinally displaceable. The lever facilitates the stackability of the trampolines due to its displaceability. When stacking you will bring the lever in such a position in which he for the adjacent (patch) trampoline no

Obstacle is. The lever can be made of metal. Another advantage of the lever is that the

Tightening torque is relatively large, resulting in a large clamping force.

The guide can be connected to the frame in various ways. For example, the guide may be bolted or glued to the frame or leg. Often the frames are made of metal, especially steel or stainless steel. In this connection it is suggested that the guide is welded to the frame. Such an attachment is particularly well able to, in the

Use of the trampoline occurring periodic loads.

It should be noted that the rod can have several functions. As already indicated at the outset, the rod can be designed as a holding rod and have at least one gripping device, on which the user can hold on while jumping or swinging. The gripping device comprises, for example, two

Handles extending laterally from the pole. Alternatively or additionally, it is possible that the rod (possibly in addition) has a receptacle for an electronic device. This can be a tablet PC or, for example, a device that measures and / or monitors the body functions of the user.

When using the rod as a support rod act on the support rod during use considerable forces. Thus, the leadership is exposed to a special burden,

especially against the background that on the leadership

Considerable due to the longitudinal extent of the support rod

Leverage forces act. In essential further development of

Invention is proposed that the frame forms a recess in which the guide is received. The recess may be a partial recess in which the frame is not fully opened (in the sense of being severed) but merely a recess in the frame

is trained. Compared to conventional solutions in which the rod or its receptacle is only welded laterally to the frame, the recess forms a larger

Contact surface, which is a substantial increase in strength entails. The initially accepted by the recess weakening of the frame is thus compensated by the attachment of the guide with the considerable advantage of a stable attachment of the guide and thus a durable and stable overall construction, including the high

Leverage forces while training on the trampoline withstands.

It is considered particularly advantageous if the

circumferential frame is broken and the guide is inserted into the resulting recess. For metal frame, the guide is appropriately welded. The frame is therefore advantageous on both sides of the guide. As a result, a large contact area can be achieved. This keeps the leadership excellent. At the same time, the frame remains stable. The use of the guide in the frame has the further advantage of a compact design. This makes the trampoline easy to stack.

Already mentioned above, it is advantageous if the guide is designed as a pipe piece. This can be a square or a round (cylindrical)

Act pipe piece. The production of a pipe section is favorable. A round shape reduces the risk of injury. An advantageous embodiment of the invention is characterized in that the pipe section perpendicular to the

Extension direction of the legs is arranged. In particular, it is proposed that the pipe section opens radially inwardly with respect to the peripheral frame. These

Embodiment is very compact. The inner piece can be inserted radially from the inside into the pipe section. His

Movement direction is preferably radial. A piece of pipe also favors the stackability. The invention allows It is that the pipe section protrudes upwards and downwards by a maximum of 2 cm over the frame, as it is basically in the context of

Invention is considered advantageous.

Preferably, the guide has an end wall. The actuating device is advantageously supported on the end wall. The thickness of the end wall will be chosen to accommodate the clamping forces the actuator exerts on it. Preferably, the actuator engages through the end wall. The actuator is suitably rotatably mounted in the end wall.

In the following, the invention is based on a preferred

Embodiment of the actuating device.

FIG. 1 shows an exemplary embodiment of a trampoline according to the invention. The trampoline has a frame 1, which is supported with a plurality of legs 2 at the bottom. The frame holds a jumping sheet 3 that has a variety of

Spring elements 4 is held on the frame. Both

Spring elements 4 may be rubber rope sections that are either open or closed. Both variants are known from the prior art. The

Rubber cord sections may be suspended in receiving elements attached to the jumping sheet, for example hook elements. Alternatively, metal springs are used, which are also known from the prior art.

On the trampoline a rod 5 is attached. The rod 5 is formed in the illustrated embodiment as a support rod and has a handle 6. Alternatively or additionally, the rod can also be a holder for a

electronic device such as a tablet PC or the like. The pole can also take on other tasks. For example, on the pole

Rubber elastic band to assist with exercises on the Trampoline be attached. For the sake of simplicity, reference will now be made exclusively to a handrail.

The support rod 5 is held in a guide 7 which is attached to the frame 1, for example screwed or welded. The guide can also be attached to one of the legs 2. The support rod 5 is adjustable in height and fixed by means of a (in Figure 1 only indicated) actuator 8 in the guide 7.

Figure 2 shows the guide 7 of Figure 1 in more detail. The guide 7 is welded to the frame 1, as can be seen by the weld 9. For this purpose, the frame 1 is where the guide 7 is used, separated and forms a recess A. This gives the overall construction a high stability at the same time elegant and slender

Design. The recess is shown in FIG. 6 for reasons of clarity. The actuating device 8 has a handle 10, which may be formed of plastic. The handle is seated on an axis of rotation 11 which has a thread, as will be described in more detail in connection with Figures 3 and 4.

Reference is made to FIG. 3, which shows a schematic illustration of a section through the guide 7. The

Guide 7 is welded to the frame 1. The frame 1 preferably comprises the guide on both sides. The frame is indicated in Figure 3 with a dashed line.

In the guide 7, the support rod 5 is slidably received in the direction of its longitudinal axis. The support rod 5 is in the guide 7 fixable. For this purpose, in the guide 7 a

Inner piece 12 is movably received. The inner piece 12 is preferably guided displaceably in the guide 7.

Preferably, the inner piece 12 is substantially

cylindrical.

The guide 7 has two openings 13, which are preferably aligned. The inner piece 12 also has an opening 14. The rod 5 is through the openings 13, 14th

push-through. The openings 13, 14 are aligned for this purpose

expedient and are preferably designed to be larger than the cross section of the rod 5, so that the rod can be inserted through the openings. At this point it should be noted that in Figure 3, only a part of the support rod is shown. The

Retaining rod may have a round cross-section.

Alternatively, it has an angular, in particular square cross-section. The openings are adapted to the cross-sectional shape of the support rod.

The inner piece 12 is coupled to the actuating device 8. For this purpose, the inner piece 7 has an internal thread 15, which is in engagement with a threaded pin 16 of the actuating device 8. The threaded pin 16 is by means of

Handle 10 turned. Due to the threaded engagement between the inner piece 12 and the actuator 8, a rotation of the handle 10 leads to a movement of the inner piece 12 in the guide 7. In this case, the

Actuator 8 on the guide 7 from. Preferably, the guide 7 has an end wall 17 on which the actuating device 8 is supported. In Figure 3, the inner piece 12 is shown in an open position. In this, the support rod 15 is movable in the guide. That is, the openings 13 and 14 are so

Aligned to let the handrail 5 enough play to be moved. Preferably, the cross section of the opening 14 of the inner piece 12 is greater than the cross section of the openings 13 of the guide.

FIG. 4 shows the holding bar 5 in a fixed state. The support rod 5 is clamped by the handle 10 of the actuator 8 is rotated so that the thread 16, the inner piece 12 in the direction of the handle 10 draws, as indicated by the arrow PI. It should be noted that the construction in principle so

can be obtained by pressing the

Actuator 8, the inner piece 12 in the other

Direction, ie opposite to the arrow PI, is moved and thus the support rod 5 fixed. Then the must

Actuator 8 on the inside 18 of the guide support to apply the force on the inner piece 12. For this purpose, for example, be provided a locking ring.

When moving the inner piece 12 in the direction of the arrow PI, the opening 14 also moves in the direction of the arrow PI until the inner side 19 of the inner piece 12 comes to bear against the support rod 5. The support rod 5 is against the

Inside 20 of the opening 13 of the guide 7 is pressed and thereby fixed. As advantageous in this

Embodiment, it is considered that the holding rod 5 is clamped with a large holding surface, which is provided by the inside 19, is clamped. This creates a stable and permanent fixation of the support rod in the

Leadership 7. It is further considered advantageous that the Guide two contact surfaces 21, 22 provides.

Preferably, the one contact surface 21 is above and one

Bearing surface 22 arranged below. In particular, the one contact surface 22 above the frame and the other

Bearing surface 22 may be arranged below the frame. Such an embodiment of the invention provides an advantageous orientation of the support rod 5 relative to the frame 1.

FIG. 5 shows an alternative exemplary embodiment to FIGS. 3 and 4. For reasons of clarity, the same or similar components are identified by the same reference numerals, even if they differ slightly from one another in terms of construction. The embodiment of Figure 5 shows the

Handrail in a fixed state. The

Embodiment differs from Figures 3 and 4 in that the actuator 8 no

Threaded, but has a nut 23. The inner piece 12 has a threaded pin 24. The inner piece 7 and the actuator 8 are threadedly engaged. By turning the handle - as in the embodiment according to Figures 3 and 4 - the inner piece 12 is pulled in the direction of the arrow PI.

Figures 6 and 7 show the interaction of the inner piece 12 and the guide 7. For clarity, the

Actuator and the support bar omitted in the illustration. In Figure 6, the inner piece 12 and the guide 7 are in a position in which the openings 13 (the guide) and 14 (of the inner piece) are aligned. In this position, the support rod can be used. Deriving from the

Overlapping the openings 13, 14 resulting cut opening must be at least as large as the cross section of Support rod, so that the support rod through the guide 7 and the inner piece 12 can be pushed.

Figure 7 shows a position of the inner piece 12 in a slightly pulled out of the guide 7 position. Here is

clearly that it is advantageous if the guide has a radially inner opening 25. Preferably, the opening 25 of the end wall 17 opposite. Through this opening 25, the inner piece 12 can be inserted for mounting in the guide 7 and pulled out for disassembly. The

Assembly is very easy. At the same time, the

Combination of inner piece 12 and guide 7 on the

Inner sides 19 and 20 a stable deadlock of the

Handrail, as stated above.

The guide 7 is advantageously as a piece of pipe

educated. Such a piece of pipe is easy to prepare and stable. In particular, the tube piece may have on one side an end wall 17, through which the actuating device or a threaded pin extending from the inner piece 12 passes (see FIG. 5).

Figure 8 shows an alternative embodiment of the

Actuating device 8. The actuating device has a tensioning lever 26. Again, the clamping lever and the inner piece are preferably in threaded engagement with each other (analogous to Figures 3 to 5). About the thread is a

Rough adjustment possible. The final clamping force is applied via the clamping lever, which is advantageously supported on an intermediate piece 27 or directly on the guide 7. The intermediate piece 27 abuts against the guide 7. The frame shape is shown only round in the figures. It can also be polygonal, octagonal particular six ^¬.

In the description, all indefinite

Locations such as "above", "below" or "laterally" refer to a standing trampoline

Location information or direction information such as used radially inside or radially outside. These are based on the frame, which may be either round (or in plan) or square. If it is round, the round frame forms a center of curvature. The information is related to this point. A guide which extends radially, therefore lies on a line extending radially from the

Center of curvature extends outward. In square

Frame shapes are regular between the corners

Frame sections provided. The guide will be arranged in the middle of the frame sections. The perpendiculars extending from the center of each frame section intersect at the center of the frame so that, for example, a length of pipe extending radially to the angular frame lies on a line going radially outward from the center. In the middle of the frame section, this line cuts the frame vertically.
