Description

The invention relates to a fall protection device for trampolines according to the preamble of patent claim 1.

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 the DE 10 2006 028 363 B3 is a so-called mini-trampoline known in which the jump sheet is suspended from 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 performed by the people alone, but rather almost exclusively in the company of an experienced physiotherapist. This involves considerable risks for both the user and the attendant. Irrespective of this, 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.

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 reduced mobility, often increase as a result of their lack of movement 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 increases significantly and thus also the health costs borne by the public.

From the US-A-4344617 is a fall protection device known by means of which a user of a trampoline can be secured against falls. For this purpose, the user wears a kind of belt, which is suspended on ropes. The ropes are on a rolling device like this rolled up, that they are removable against a spring force from the role. This keeps the ropes taut when using the trampoline. The fall arrest device has a clamp that limits the cable pullout in the event of a fall.

From the US 4,449,716 is a fall protection device for trampolines is known, the two ropes are also fastened to the user of the trampoline. The two ropes are wound around two lever arms, which are pivotally coupled against a spring force and hold the two ropes taut. The opposite movement of the two lever arms can be stopped by a cable pullout limiting device, which is triggered by a supervisor.

The known fall protection device is dependent on a supervisor. In addition, the tensioning device is mechanically complex and cumbersome.

• ■ Diese Aufgabe wird durch eine Fallschutzvorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst.

The invention has for its object to provide a fall protection device, on the one hand a safe training independent of additional supervisors allowed and their tensioning on the other hand, as simple as possible.

• This object is achieved by a fall protection device having the features of patent claim 1.

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 a heavier disability.or also for fall-endangered seniors to train independently on a trampoline alone, without being exposed to a momentous fall risk. This training promotes / activates essential body functions in people with restricted mobility (Bladder incontinence / digestion) and supports an unusual for the life situation energy consumption.

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 tensioning device exerts the least possible retraction force on the user to train the natural sense of balance and related reaction skills.

From the WO 03/035184 A1 ,of the DE 198 05 164 C1 and the US 5,704,881 are known security systems. 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, the patients should wear their own body weight during trampoline training. The retraction force of the tightening device should be so be as small 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, during downswing the body experiences an increasing weight force. During the downswing, the patients on the trampoline sink significantly below the zero level (ie the level in which the trampoline is loaded with the body weight in the rest position). 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 trampoline. The tensioning device is thus designed so that when using the trampoline over the entire oscillation amplitude on the one hand sufficient rope provided 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 event of a fall, the rope extension is limited by the device for limiting the rope extension. It is therefore impossible for the user to fall off the trampoline or to be exposed to a risk of injury. This is especially true when the cable pullout is limited so that the user of the trampoline does not "fall low", but is already caught immediately after an accidental leaving the usual swing curve. In such an early caught position it will be the user in all Usually be possible to take the training position by itself again. Targeted fall-depth regulation allows patients to learn how to absorb themselves from lower lintel positions with increasing reflex competence.

Suspensions for trampoline users are known in the art, which have elastic ropes. Such (highly) elastic ropes are completely unsuitable for the invention. In the invention, it is of central importance that the user is not catapulted out of the (unwanted) camber position in the event of a fall, but is held in the camber position, so that subsequently the possibility exists to return 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 rubber cord or woven elastic cord which has the aforementioned disadvantages.

The user should in the therapy - in addition to building muscle - sharpen the feeling of balance and all the necessary reaction and compensatory reflexes.

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

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 fall protection device according to the invention, a rope is used, which is not elastic substantially. Nevertheless, a suspension of a fall is desirable. In a further development of the invention, it is therefore proposed that the device for limiting the cable separation 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, pneumatic or hydraulic dampers, which absorb a possible fall.

Preferably, the degree of damping of 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 around which the rope is wound. In the event of a fall, the cable end and the pulley move towards each other until the cable pullout is limited.

The damper can act as a stop itself. Alternatively, you will provide a separate stop to limit the cable extension, so that the damper exclusively assumes the damping function.

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 displaceable carriage, which can be brought into engagement with the rack. The rack allows on the one hand a fine screening, so a precise adjustment to 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 embodiment of the invention is characterized in that the drop height 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 set to within a few centimeters of the vibration amplitude, so that the user can be caught in loss of balance before any actual lintel occurs. The user must not fall too low otherwise he might not be able to straighten himself up. In addition, in the case of too deep a fall, there is a considerable risk of injury. The objective is to convey fall experience and to train the user to avoid fall-offs.

According to the invention, a tensioning device is provided, which has a device for deflecting the rope. The means for deflecting the rope may have a roller which causes a deflection of the rope. Preferably, the Tightening means a pivotable lever over which the cable is deflected in use. Due to the deflection of the rope, the cable section connected to the user is shortened. Such a construction allows a safe 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. This also 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 thus separated from each other. It can also be provided that the tensioning device and the device for limiting the cable extension are spatially separated from each other.

The basic setting of the lever is to be chosen so that the lever in the weighted rest position, in which the user is standing on the trampoline but has not yet moved, already deflects the rope. During the subsequent swinging up and down, the cable is increasingly deflected (swinging up) and less deflected (swinging).

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

As it has proven advantageous that the lever rests with bias on the rope. Basically, it is conceivable that the lever deflects the rope only 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 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 (for this purpose, the lever also has a role) and with its other end, the lever is attached to the fall protection device, wherein the rope is guided over the deflection roller. Such a construction is smooth, reliable, compact and durable.

According to the invention it is provided that the rope limiting device only triggers when the cable extension has reached a defined length. This length is reached when the patient leaves the normal swing path (plus a safety factor, if applicable). The invention is characterized in that the means for limiting the cable extension is only triggered 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 damped, 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. This holds however, there may be a risk that the ceiling will not hold the fall arrest device. In that regard, it is considered particularly advantageous if the device has a boom. The boom reaches above the user.

The boom will be fixed 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, therefore, a system can be provided by the manufacturer, which has a static and dynamic stability in itself. The system only needs to be attached to a wall, with the vertical forces being dissipated via the vertical support.

Also a freestanding construction is 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. you will still gain 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, 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, advantageously is configured so that the cable length is adjustable by moving at least one of the pulleys.

The fall protection 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 trampoline. 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 from the starting position, the feeder and can be advantageously supported on this and thus reach the trampoline. 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 unlatch the safety device.

The invention is primarily geared 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, as mentioned above, the user will wear a vest in which the rope will be latched on one side in the region of the shoulders.

To adapt to the user (in size and / or width), the cable is preferably guided over a flexible, in particular a pivotable deflection roller. If a boom is used, you will provide the flexible pulley in the end of the boom. In concrete embodiment, the deflection roller may be mounted for example in a holder which is pivotally mounted on the boom. An alternative embodiment is characterized in that the deflection roller 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 attached drawings . Here are only the FIGS. 6 and 7 from the claims. The drawing shows in:

a further detailed view of the embodiment according to FIG. 6 ,

FIG. 1 shows the operating principle of a fall protection device based on a first example. In FIG. 1 schematically two states are shown. On the left in FIG. 1 a handicapped person 1 accesses a feeding device 2, on which the person can rest. The feeder 2 is slidably mounted on a rail 3. For this purpose, the feed device 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 is formed in the present case 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 supported, which moves along the rail 3 to the training position by the right person in FIG. 1 is marked.

If the person has arrived on the trampoline 8, the person will first secure himself with a second rope 10 - the training rope - before it disengages the first rope 6. The second cable 10 is latched as well as the safety device 6 in the vest in the shoulders of the person 1. For additional stabilization, the person can hold on a support rod 11.

On the trampoline 8, the person performs 1 their vibration exercises. The rope 10 is tracked to the amplitudes of the vibrations of the trampoline mat. 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. As a result, the rope extension is limited and the person is 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 deflected by further rollers 16, 17 and 18.

The fall protection device is repeatedly adjustable. A first adjustment of the usable rope length is made via the roller 17, which is arranged displaceably in the direction of the double arrow. By moving the roller 17 to an upper position, the usable rope length is longer and vice versa. This allows you to adjust, for example, the usable rope length to the height of the user 1.

A second adjustment is made by the stop 13. This stop is adjustable in the direction of the double arrow.

By adjusting the stop, for example, the catch height can be adjusted after a fall. Thus, the deceleration of the person in case of a fall is not too abrupt, the stop 13 is provided with a damping device 19. This may be, for example, a rubber or plastic buffer, a gas cylinder or a pneumatic or hydraulic damper.

In the example shown, the damping device 19 is assigned to the stop 13. Also, the damping device 19 may be assigned 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 for easy adjustment and fixing in a desired position.

FIG. 2 shows the rear end of a second embodiment of a fall protection device in a frontal view. Compared to FIG. 1 It is clear that here two ropes 10 are used, each rope 10 is hooked or hooked on one side of the user's vest (not shown here).

The rope 10 is deflected several times, via a fixed roller 22, an adjustable roller 23 and stationary rollers 24. At the end of the rope 10, the weight 12 is fixed in each case, that 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.

• A Traverse, auf der die Rollen 24 gelagert sind;
• B Traverse, die zusammen mit den Dämpfern 19 den Anschlag 13 bilden;
• C Gewichte 12, die mit dem Seil 10 verbunden sind;
• D Obere Antriebseinheit zur Verstellung des Anschlags 13 in Pfeilrichtung;
• E Untere Antriebseinheit zur Verstellung der unteren Rollen 13;
• F Traverse, auf der die Rollen 23 gelagert sind;
• G Lagerung für die Gewindestange 26.

The example 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 the stop 13 in the 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 example 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. Overall, the boom 14, the vertical support 31 and the horizontal support 32 in the side view substantially a Z-shape. Here, the vertical support 31 jumps forward so that the aforementioned modules are behind the plane formed by the vertical support (s) 31 and extent protected.

FIG. 4 shows the second example 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 course of the rope was essentially already associated with FIG. 2 explained.

Out FIG. 4 shows how the rope over the rear pulleys 22 to the front portion of the boom 14 and over the front guide rollers 15 are guided in the direction of the (not shown) user. The deflection rollers 15 are received in a holder 35, which allows the deflection rollers are pivotable inwards. 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 two cables 10 are used in the example shown, the fall protection device allows a symmetrical construction of the overall construction. In addition, the modules A, B, D, F and G are designed to carry the respective assemblies for the left and right cables. Only the module C, which includes the weights 12, is formed individually, since the respective cable 10 must be individually operable.

FIG. 5 shows a simplified compared to the second example version of a fall arrest device. In this case, the adjustable module F and the associated modules E and G have been dispensed with. The setting of the usable rope length and the adjustment of the fall height is done exclusively via the Drive unit D, which adjusts the stop module B. In the lower region of the fall protection device, instead of the modules E, F and G, only one module H is arranged, which carries two deflection rollers 34.

In the FIGS. 6 and 7 an embodiment of the fall arresting device according to the invention is shown, wherein in FIG. 6 a device for limiting the rope extension and in FIG. 7 a tightening device is shown.

It will open FIG. 6 Referenced. 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 mounted on external spars 38 and 39, 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 intended position, the handle 40 is folded over and the carriage 41 engages in the rack 42 a.

In the normal training position, the trusses L are each held by a damper 43 in the upper position, as shown. The damper is supported at one end on the lower cross member N and at the other end on the movable cross member L.

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 cable 10 is guided downwards via a first deflection roller 44, which is fastened to the stationary traverse M, and subsequently via a deflection roller 45, which is associated with the movable traverse L. The end of the rope 10 is fixed to the traverse M.

In the event of a fall of the user, the rope 10 is pulled in the direction of arrow P1. As a result, the cross member L moves in the direction of the traverse M, and indeed until it comes to rest 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 stroke of the gas spring is adjustable, such that the starting position can be set. By presetting the damper 43, it is thus possible to adjust the damping path and thus adapt to the user. The adjustment is indicated by the adjusting device 47.

It will open FIG. 7 Referenced. FIG. 7 shows a boom 14 of the fall protection device according to the invention. The cable 10 is guided by the user (not shown) via the guide roller 15 to the rear, ie in the FIG. 7 to the left.

The tensioning device according to the invention is formed by a lever 48. The lever has a lever arm 49 which on the Boom 14 is pivotally mounted. At its end a guide roller 50 is fixed, with which the lever arm deflects the cable 10. For better illustration, four different operating states of the lever 48 are shown, wherein in the uppermost position of the lever arm 49, the rope 10 is taut and in the lowermost position the (dash-lined illustrated) cable is deflected.

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 the lever arm 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 the trampoline 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 evenly 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 (safety line), rope tensioning device and fall limiting device. The Fallbegrenzungseinrichtung is not necessarily understood in the sense of the invention only as a stop. As related to FIG. 6 executed, the limiting device may comprise a plurality of components, in particular a stop or the like, the end position defined, if necessary deflection roller (s) and a damper. The limiting device thus advantageously provides a cable pull-out, within which the user / patient is first braked and finally collected safely. The collecting position and / or the triggering position at which the rope boundary is introduced are preferably adjustable.
