description

The invention relates to a fall protection device for trampolines.

Trampolines have found a firm place in modern physiotherapy. Exercises on a trampoline address most of the muscles of the human body. With a single simple exercise device, a variety of muscle can be activated and trained. Training on a trampoline also has a positive impact on the metabolism and trains the sense of balance.

From 10 2006 028 363 B3 a so-called mini-trampoline is known in which the jumping cloth is suspended on individual elastic rope sections. The trampoline has proven itself in the leisure sector as well as in the physiotherapeutic field and in the preventive health promotion.

So far, trampolines have already been used for people with disabilities. However, the exercises could not be done by the persons Alone, but rather almost exclusively in the company of an experienced physiotherapist. There are significant risks for both the user and the lead person. Regardless, the associated personnel costs are considerable. The invention is directed in particular to groups of persons with disabilities and persons at risk of falling. However, the applications of the invention are not limited to this group of people kt.

People with progressive disabilities such as multiple sclerosis, dementia or Parkinson's disease as well as seniors quickly lose their musculature and their balance due to a lack of exercise. Due to dwindling activity, this group of people is increasingly exposed to risks of falling. Even persons with different birth disabilities (such as spasticity) or persons who have to live as a result of an injury with limited mobility, as a result of their lack of movement often strongly to body weight and thus lose additional mobility. The same applies to aging people.

The loss of muscle power and balance has fatal effects on the personal mobility and quality of life of those affected. In addition to the direct impact on the persons affected, the lack of physical activity also has an impact on society. In particular, the need for care is increasing significantly, and with it also the health costs borne by the public.

The invention has for its object to make the positive effect of training on a trampoline also users with disabilities and balance impairments safely accessible. To solve this problem, the aforementioned fall protection device according to the invention is characterized by

^■ at least one rope that is connectable to a user of the trampoline,

^■ at least one tensioning device that keeps the rope taut when using the trampoline, and

■ at least one device for limiting the cable extension.

The fall protection device according to the invention opens up completely new possibilities in therapy. For the first time, it is also possible for persons with severe disabilities or those who are at risk of falling to train independently on a tra mpolin without being subjected to a momentous fall risk. This training promotes / activates essential body functions (bladder incontinence / digestion) in people with limited mobility and supports an unusual energy consumption for the life situation.

The rope is preferably substantially nonelastic. This may be, for example, a wire rope or a natural or synthetic fiber rope.

The substantially non-elastic rope is connected to the user before using the trampoline. For this purpose, the user preferably wears a safety vest, in which the rope is latched. When swinging on the trampoline, the rope is pulled out and retracted and kept taut by the tensioning device. The aim is that the taut restraint exerts the least possible retreat force on the user to the natural Sense of balance and being able to train with connected reactivities.

From WO 03/035184 Al and DE 198 05 164 Cl security systems are known. The known safety systems are used in treadmills and locomotion systems. In addition to securing the user, they serve purposefully to lift the user (patient) so that he is only burdened with a part of his body weight when walking / running. By design, the known security systems are designed exclusively for the user to move in or above the walking / running plane.

The known systems are unsuitable for use with a trampoline. The users are partially raised by the known systems, partially positively controlled. In the invention, however, patients should wear their own body weight during trampoline training. The retracting force of the tightening device should be as low as possible so that the patient can train balance reflexes and fine motor skills under realistic conditions.

Moreover, in the use of the trampoline according to the invention, the patient is exposed to conditions which are not comparable to a (weight-assisted) walking training. During the upswing, the body experiences a relative weightlessness. When the body recovers, the body experiences an increasing weight force. In the downswing, the patients sink significantly below the zero level (ie the level at which the trapolpolin is burdened with the body weight at rest) on the tra polypin. The undisturbed sensing / experiencing of these states is essential for the therapeutic effect. Again, the known systems are not designed. According to the fall protection device allows training on the Tra mpolin. The tensioning device is thus designed so that when using the Tra mpolins on the whole Schwingu ngsamplitude sufficient rope provided on the one hand and on the other hand kept taut. At the same time, the pulling force of the rope is adjusted so that the patient does not feel the rope subjectively or only to a very small extent. The main function of the rope is therefore to secure the patient in case of a fall.

In the case of a fall, the cable extension is limited by the device for limiting the rope extension. It is therefore impossible that the user of Tra mpolin falls or exposes himself to a risk of injury. This is especially true when the cable pullout is limited so that the user of the Tra mpolins not "low", but is already caught immediately after an unwanted leaving the usual swing curve In such an early caught position, the user in al As a rule, it is possible to automatically regain the training position by means of a targeted fall-depth regulation, which allows patients to learn to safely catch themselves from lower lintel positions as reflex competence increases.

From the prior art are suspensions for k

Trampoline users known to have elastic ropes. Such (highly) elastic ropes are completely unsuitable for the invention. Of central importance in the invention, it is namely that the user in the event of a fall not catapulted out of the (unwanted) lintel position, but is held in the lintel position, so anschending the possibility exists to go back to the training position. According to the invention, the rope should be substantially non-elastic. This feature takes into account that each rope always has a certain elastic content. However, according to the invention, it is not intended to use a pure gum miseil or woven Elasti kseil to m Einsatz com men, which has the aforementioned disadvantages.

The tensioning device can be for example a weight. The size of the weight should be chosen so that it keeps the rope substantially taut on the one hand, but on the other hand influences the user's perception as little as possible. The user should in the therapy - in addition to building muscle - sharpen the feeling of balance and all the necessary reaction and compensatory reflexes.

As an alternative to the weight, a spring-loaded retractor can be used.

An advantageous embodiment of the invention is characterized in that the means for limiting the cable extension has a stop. The attachment defined defines the end position of the patient in the event of a fall.

It can be provided that the tensioning device cooperates with the stop. In this case, the tensioning device itself is designed as a rope-side stop.

Basically, it has been proven that the tightening device is guided. This has the advantage that any additional forces are avoided by an unwanted swinging of the tensioning device.

In the case of the fall protection device according to the invention, a rope is used that is essentially not elastic. Nevertheless, a suspension of a fall is desirable. In training of Invention is dahe ^r proposed. the device for limiting the cable extension has at least one damper. This may in particular be a gas spring, a spring or, in certain cases, a rubber or plastic stop. Basically advantageous, for example pneu matic or hydraulic damper, which cushion any lintel.

Preferably, the Dämpfu ngsgrad the damper is adjustable. The fall protection device according to the invention can thus be adapted individually to users with different body weights and / or training progress.

Suitably, the damper is coupled to one end of the rope. The other end is advantageously coupled to a pulley, u m the rope is wound. In the event of a fall, the end of the rope and the lifting roller move towards each other until the extension of the rope is limited.

The damper can itself act as a stop. Alternatively, you will provide a separate stop to limit the pull-out, so that the damper only the Dämpfungsfun ction over mim.

In an essential embodiment of the invention it is proposed that the cable length of the free end of the rope is adjustable. The fall protection device according to the invention can therefore be adjusted to the body size of the user.

It has proven to be advantageous to adjust the cable length by adjusting the device for limiting the cable extension. For example, it can be provided that the fall protection device comprises a stationary rack, and that the adjustment of the cable length via a sliding carriage which engages with the rack is brinπhar. The rack on the one hand has a fine grid, so an exact adaptation of the user. On the other hand, the rack provides a firm and secure lock.

For fall prevention training, the patient must be progressively familiarized with different lintel heights. To meet this, an advantageous Ausfüh tion of the invention is characterized in that the height of fall of the user is adjustable. This defines the end position of the patient in the event of a fall. As a rule, a fall height adjustment will be made via the setting of the device for limiting the cable extension. In particular, it can be provided that the adjustment takes place via the damper.

When setting the fall height, it should be noted that in the initial stage of training, the cable pullout is preferably adjusted to only a few centimeters deviation from the vibration amplitude, so that the user can be caught if the balance is lost before an actual lintel occurs. The user must not fall too low, otherwise he may not be able to rebuild himself. In addition, in the case of a too deep fall, there can be a considerable risk of injury. The objective is to convey fall experience and to train the user to avoid fall-offs.

As already stated above, the tensioning device may be designed in a simple construction, for example as a weight. Particularly advantageous is considered a direction of detraction, which has a direction A for the deflection of the rope. The device for deflection of the cable may have a roller which causes a deflection of the cable. Preferably, the penalty device has a pivotable lever over which the rope is deflected during use. Due to the deflection of the rope, the cable section connected to the user is shortened. Such Konstru ktion allows a secure tightening of the rope even with fast load changes.

A significant advantage of the lever is the relatively low-noise function. As a result, the patient experiences no irritating noise during the exercises, which allows him to feel safe and to concentrate fully on his movements. Incidentally, the construction of the lever may be such that it has a low weight only. This, too, has an advantageous effect on the perception of the patient.

The tensioning device is preferably decoupled from the device for limiting the cable extension. Their functions are separated a lso. It can also be provided that the device and the device for limiting the Seila extension are locally separated from each other.

The basic setting of the lever should be such that the lever in the weighted resting position, where the user is standing on the tractor, but not yet moving, already deflects the rope. During the subsequent swinging up and down, the cable is increasingly deflected (swinging up) and less kung (swinging).

From a certain point expedient no deflection takes place. Then the rope is just stretched. In this position, the device can be triggered to Begrenzu ng of the cable drawer, as will be explained in more detail below.

As it has proven advantageous that the lever rests with bias on the rope. In principle, it is conceivable that the lever only deflects the rope with its own weight. However, it is particularly advantageous if the bias of the lever is adjustable. This can be done for example by a spring, in particular a coil spring, which is arranged in the region of the suspension of the lever.

A preferred embodiment of the lever is dad urch characterized in that the lever is mounted on one side and that on the bearing axis of the lever, a pulley for the rope is arranged. With its one end, the lever thus deflects the rope (this, the lever also has a role) and with its other end, the lever is attached to the fall protection device, the rope is guided over the U mlenkrolle. Such a construction is smooth, reliable, compact and durable.

In principle, it is advantageous if the rope limiting device only triggers when the cable pullout has reached a defined length. This length is reached when the patient leaves the normal swing path (plus a safety factor, if applicable). A particularly advantageous embodiment of the invention is characterized in that the device for limiting the cable extension is only released when the deflection is canceled. In normal training mode so the tightening device acts. In the case of a fall, the deflection is lifted and the entire rope is tightened so that it triggers the device for limiting the rope extension. Practically, the limitation of the cable extension is introduced attenuated so that the user does not fall too hard.

In a very simple embodiment, the fall protection device according to the invention can be suspended from the ceiling. However, this may involve the risk that the ceiling does not hold the fall protection device. In that regard it is considered special considered advantageous if the device has a boom. The boom reaches above the user.

The boom will be fastened directly to a side wall or preferably to a vertical support which in turn is attached to the wall. With the vertical support and the boom so the manufacturer can be made available a system that has a static and dyna mix stability in itself. The system only needs to be attached to a wall, with the vertical forces being dissipated via the vertical support.

A freestanding construction is also conceivable.

Preferably, the boom protrudes with its front end over the trampoline. The boom is so dimensioned that a conventional mini-trampoline can be accommodated under the boom. Possibly. will still provide access to the trampoline under the boom, as will be explained in more detail below.

The tensioning device and / or the limitation of the cable extension are advantageously arranged in the rear region of the boom. In particular Kings nen the aforementioned elements in the vertical support structure, so for example between two vertical supports, be arranged. There they are well protected and easy to use.

At the front end of the boom will be a deflection, in particular a guide roller, arrange, which leads the rope to the rear end of the boom. Preferably, the rope is deflected there by a Umlenkrollensystem, which is advantageously designed so that the cable length is adjustable by moving at least one of the pulleys. The safety device can be used in different versions. The versions may be adapted to different levels of users' performance or patient disability. In patients with a greater disability, it is advantageous if an aid is provided, through which the patient reaches the trampoline and the tra polypin. An advantageous construction is characterized in that the device has a feed device, which is arranged displaceably along the arm. The user will therefore grab the feeder from the starting position and can advantageously be supported on this and thus reach the Tra mpolin. The feed device can be designed such that an upper carriage slides on a rail connected to the boom.

In addition, a safety device may be provided to secure the patient. The safety device may be a rope or a belt system or the like, which the user latches into the already existing safety vest. Once the user has arrived on the trampoline, he will engage the training rope and ausklin ken the safety device.

The invention is primarily directed to users with disabilities or gangs. With the help of the trampoline a variety of muscles in the body is strengthened and trained. At the same time, sense of balance and fall-avoidance reflexes are trained. For this it is important that the user / patient does not receive strong active support in the sense of an upward pulling force. Too strong a tensile force would falsify the feeling of equilibrium.

In this context, it is proposed that not only one (pull) rope, but two independent ropes are provided, which secure the user on both sides. In practice, the user will like previously mentioned, wearing a vest, in which the rope is latched in each case on one side in the shoulders.

To adapt to the user (in size and / or width), the rope is preferably guided via a flexible, in particular a verschwen kable U mlenkrolle. If a jib is used, the flexible diverter will be provided in the end area of the jib. In con creter design, the order directing roller can be stored for example in a holder which is verschwen kbar supported on the boom. An alternative embodiment is characterized in that the Umlen krol le attached to a wire rope, which is suitably attached to the boom. The flexible wire rope allows flexible alignment of the rope.

Both ropes are advantageous each connected to the tensioning device.

In the following the invention will be explained in more detail with reference to a preferred embodiment in conjunction with the appended drawing. The drawing shows in:

Figure 2 is a schematic representation of a second embodiment of a fall protection device according to the invention;

FIG. 3 shows the fall protection device according to FIG. 2 in a side view; Figure 4 shows the Fallschutzvorrichtu ng of Figure 2 and 3 in a perspective view;

Figure 5 is a schematic representation of a third embodiment of the invention;

Figure 6 is a detail view of a fourth embodiment of the invention; and

Figure 7 shows two more detail views of the fourth embodiment.

Figure 1 shows the principle of operation of the fall protection device according to the invention with reference to a first embodiment. In Figu r 1, two states are shown schematically. On the left side in Figure 1, a disabled person 1 accesses a feeder 2, where the person can support. The feeder 2 is slidably mounted on a rail 3. H here, the feeder 2 has a carriage 4, which slides with two rollers 5 on the rail 3.

In addition to the support of the person by the feeder 2, the person is secured to a safety device 6, which in the present case is designed as a rope, wire or belt system and connected to the carriage 4.

The person 1 wears a safety vest 7, in which the safety device 6 is latched in the region of the shoulders.

To get to the trampoline 8, the person 1 must first go in the direction of the trampoline and climb, for example, a staircase 9. Here, the person 1 at the feeder 2 support, which moves along the rail 3 to the training position, which is characterized by the right person in Figure 1.

If the person has arrived on the Tra polpolin 8, the person will first secure with a second rope 10 - the training rope - before it ausklin kt the first rope 6. The second cable 10 is like the safety device 6 in the vest in the shoulders of the person 1 einklink kt. For additional stabilization, the person can hold on to a support rod 11.

On the trampoline 8, the person performs 1 their vibration exercises. In this case, the rope 10 is tracked to the amplitudes of the vibrations of the tram poli nmatte. For this purpose, a weight 12 is attached to the end of the rope 10, which keeps the rope always substantially taut. In the event of a possible fall of the person 1, the weight 12 strikes against a stop 13. This will limit the movement and the person will be intercepted despite the fall.

The rope 10 is deflected several times. In the front region of the boom, a first guide roller 15 is arranged, via which the cable 10 is guided on the rear side of the boom. Subsequently, the rope 10 is about other rollers 16, 17 and 18 kt kt.

The fall protection device is repeatedly adjustable. A first setting of the usable rope length is vorgenom on the role 17 men, which is slidably disposed in the direction of the double arrow. By moving the roller 17 in an upper position, we used the usable rope length longer and u. This allows you to adjust, for example, the usable rope length to the height of the user 1. A second shot will be made to stop 13. This Ansch lag is adjustable in the direction of the double arrow. By adjusting the stop, for example, the catch height can be adjusted after a fall. Since the deceleration of the person in the case of a fall does not occur abruptly, the stop 13 is provided with a damping device 19. These may be, for example, a rubber or plastic buffer, a gas cylinder or a pneumatic or hydraulic damper.

In the embodiment shown, the damping device 19 is assigned to the stop 13. It is within the scope of the inventive idea to assign the damping device 19 to the weight.

The reference numeral 20 denotes a second stop which has an additional safety function and acts as an end stop.

The adjustable roller 17 and / or the adjustable cable-limiting device 13 are guided on rails or rods 21. This allows easy adjustment and Festleg ung in a desired position.

Figure 2 shows the rear end of a second embodiment of the fall protection device according to the invention in a frontal view. Compared to Figure 1 it is clear that here two ropes 10 are used to COM, each rope 10 is hung or eingea kt on one side of the (not shown here) vest of the user.

The rope 10 is deflected several times, u indeed via a fixed roller 22, an adjustable roller 23 and fixed Rolls 24. At the end of the rope 10 each weight 12 is attached, which keeps the rope taut. In the end position, the weights 12 strike against the stop 13, being damped by the buffers 19. The weights 12 are guided on / on rods 25.

The embodiment shown has the following modules:

A Traverse on which the rollers 24 are mounted;

B Traverse, which together with the dampers 19 form the stop 13;

C weights 12 connected to the cable 10; D Upper drive unit for adjusting stop 13 in

Arrow direction;

E Lower drive unit for adjusting the lower rollers 13; F Traverse on which the rollers 23 are mounted; G Support for the threaded rod 26.

The fixed modules A, D, E and G are attached to a vertical strut 27. The module B is set via the drive unit D. The latter has a hand crank 28, via which a threaded rod 29 can be actuated, which is in threaded engagement with the module B. The module F is set via the drive unit E. The latter has a hand crank 30, which drives the threaded rod 26, which is in threaded engagement with the module F. It is understood that instead of the hand crank and motor drive units can be used.

FIG. 3 shows the second exemplary embodiment in a side view. The boom 14 is connected to a vertical support 31, which derives a large part of the forces of the boom. For reasons of clarity, the vertical support is shown semi-transparent. About horizontal supports 32, the fall protection device is against the wall. Insgesa mt form the boom 14, the vertical support 31 and the Horizontal support 32 in the side view substantially a Z-shape. H hereby, the vertical support 31 jumps forward so that the aforementioned modules are behind the plane formed by the vertical support (s) 31 and insofar protected.

Figure 4 shows the second embodiment in a perspective view. The fall arrest device is fastened to a wall (not shown) with an upper transverse web 34 and optionally a lower transverse web 33. The cable course has already been explained essentially in connection with FIG.

From Figure 4 shows how the rope over the rear pulleys 22 to the front portion of the boom 14 and the front U mlen scoops 15 are guided in the direction of the (not shown) users. The Umlenkrol len 15 are received in a holder 35, which allows the Umlen rollers are verschwen inward kbar. As a result, the cable guide can be adapted particularly advantageously to users with different shoulder widths or users with different sizes. The adjustment is done automatically by the cable.

Since in the illustrated embodiment, two ropes 10 men to use m men, the fall protection device according to the invention allows a symmetrical structure of the overall construction. In addition, the modules A, B, D, F and G are designed so that they carry the respective assemblies for the lin ke and the right rope. Single Lich the module C, which includes the weights 12 is formed individually, since the respective cable 10 must be individually operable.

Figure 5 shows a comparison with the second embodiment simplified version of the fall protection device. This refers to the adjustable module F and the associated modules E and G. waived. The setting of the usable rope length and the setting of the fall height is done exclusively via the drive unit D, which adjusts the stop module B. In the lower part of the fall protection device, instead of the modules E, F and G, only one module H is arranged, which carries two rollers 34.

In the figures 6 and 7, a fourth embodiment of the fall arresting device according to the invention is shown, wherein in Figure 6, a device for limiting the cable pullout and in Figure 7 ei ne tensioning device is shown.

Reference is made to FIG. The embodiment shown has five traverses. The trusses K, M and N are coupled together, namely the trusses N and M via a locking device 36 and the trusses M and K via guide rails 37. The two trusses L are in a horizontal plane and are movable separately. All trusses K, L, M, N are about Außenhol me 38 and 39 stored, the two traverses L in addition to the guide rails 37th

The adjustment of the length of the rope 10 is made via the locking device 36. For this purpose, the locking device 36 has a handle 40, via which by means of an eccentric a cross member connecting the trusses M and N 41 in engagement with a stationary rack 42 can be brought. By moving the carriage 41, all trusses along the rack 42 are moved up or down. In the proposed Stel development of the handle 40 is folded and the carriage 41 engages the rack 42 a.

In the normal training position, the traverses L uber one damper 43 in the upper position - as shown - held. The damper is supported by one end at the bottom Traverse N Lind with his other EnHp on the movable Traverse L from.

The detail of the illustrated fall protection device represents the rear portion of the fall protection device. This rear portion may be attached to a wall, for example.

The rope 10 is guided downwards over a first U mlenkrolle 44, which is fixed to the stationary cross member M, and then via a guide roller 45 which is associated with the movable cross member L. The end of the rope 10 is fixed to the traverse M.

In Fal le a fall of the user, the rope 10 is pulled in the direction of arrow Pl. As a result, the cross member L moves in the direction of the traverse M, and indeed until it com mets on a damping ring 46. The rope extension is limited. The movement is damped by the damper 43. Alternatively, the Traverse L strikes directly on the Traverse M. Another possibility is that the damper 43 itself has an integrated stop.

The damper shown is a gas spring. The H ub of the gas spring is adjustable, such that the starting position can be set. By Voreinstel ment of the damper 43, it is possible to adjust the damping path and thus adapt to the user. The adjustment possibility is indicated by the adjusting device 47.

Reference is made to FIG. Figure 7 shows a boom 14 of the fall protection device according to the invention in two views, namely both in a side view and in a plan view. The cable 10 is guided by the user (not shown) via the guide roller 15 to the rear, so in the figure 7 to the left. The erfinderggsgernaße tightening device is formed by a lever 48 d. The lever has a lever arm 49 which is pivotally mounted on the boom 14. At its end a guide roller 50 is fixed, with which the lever arm, the cable 10 auslen kt. For better illustration, four different operating states of the lever 48 are shown, wherein in the uppermost Stell ung the Hebela rms 49, the rope 10 is taut and in the lowest position the (dash-lined shown) is deflected cable.

About a guide roller 51, the rope 10 is guided downwards. The continuation of the rope 10 can be found in FIG. 6.

Preferably, the lever 48 has a further deflection roller 52, which is advantageously mounted on the axis of the lever arm 49. The bias of Hebela rms 49 on the rope 10 is adjustable. For this purpose, a worm spring is arranged in the bearing housing 53 of the lever arm 49.

During use of Tra mpolins the rope 10 is withdrawn and retracted with each vibration. So that the user does not experience any externally determined load changes, which have a negative effect on the sense of balance, an essential requirement of the fall protection device is that the rope is held as uniformly as possible and with as little resistance as possible. The lever 48 meets this requirement in a particularly advantageous manner.

In the foregoing, a fall arrest device has been described that allows training of patients on a trampoline. It consists of the essential components rope (Sicherheitslei ne), rope tensioning device and Fallbegrenzungseinrichtung. The Fallbegrenzungseinrichtung is not necessarily understood in the sense of the invention only as a stop. As stated in conjunction with FIG. 6, the Begrenzunqseinrichtunq a ufweisen several components, in particular a stop or the like, which defines the end position, if necessary deflection roller (s) and a damper. The limiting device thus advantageously provides a pull-out movement, within which the user / patient is first braked and finally safely caught. The collecting position and / or the triggering position at which the rope boundary is introduced are preferably adjustable.
