DE19600371A1 - Mobile device for coordination and interactive training or for treatment of kinesic disturbances - Google Patents

Abstract

The device is in the form of a part spherical dish with a ridge (2) around its circumference in which an elastomer ring (7) is mounted. The ring limits and buffers the rocking movement of the dish. The disc supports either a fixed plate, for when the device is used by handicapped patients, or a floating disc.The floating disc has a part spherical lower surface which matches the spherical shape of the disc. The floating disc is supported in the dish on balls which are held in a cage.

Description

The basic principle of all coordination and balance training devices is fulfilled by a board, which is placed over a round stone in an unstable balance. Further developments concern the different integration of this round stone as a joint or rolling surface in a technical form.

The use of bullets or other moving objects as objects for balancever averaged target movements according to the law of gravity corresponds to the same principle. Further developments concern games of skill in which these objects determine certain objects Must pass through lanes or target points on a playing surface.

Different coordination (balance) training devices, some with a game support surface, are described (see site register p.6), which allow rocking, wobbling and rotating movements due to their spherical shape and convex rolling surface against solid ground, but essentially the following defects exhibit:
A Danger to people practicing and those in the area of action of the device, especially small children and the elderly
B Not being able to perform certain movement qualities and spatial positions, in particular with regard to the therapy of patients with kinesis (e.g. Parkinson's)
C No or unsuitable movement animation or feedback control for children or adults with kinesis, especially children with severe disabilities
zu A In the foreground is the danger to people in the action area of the device from rolling over the limbs (in the case of small children also the head) because they can reach in unhindered or are detected due to unpredictable movements of the device. There is an increased risk of crushing and breaking injuries with narrow, inelastic or unprotected drain edges and / or high leverage forces.

Despite the anti-slip covering, patients with kinesis have too little grip the footprint, this creates a risk of joint overload and injury elderly patients, toddlers can fall or roll.  

There is an increased risk for practicing and bystanders if the tendency to tip is not limited or the stabilization weight is insufficient. With the known construction proposals in the form of a spherical cap, the patient has only two alternatives from the start of the training:
he keeps his balance or falls from the device or is intercepted or supported by the therapist. In the event of incorrect movements, fatigue or convulsions, the device must fall out of unstable equilibrium (assistance does not change the principle of operation).

to B Important movement qualities and functions are missing:

• - Interactive training of at least two people on the device, so that patient and therapist can perform and control movements together,
• - Slow and flowing fine-tuned coordination at the beginning of the training movements from a safe stand,
• - rhythmic movement harmonization under feedback control,
• - Static and dynamic tests for spatial awareness and stabilization in the Standing, sitting and lying,
• - approximately straight-line lateral acceleration from a stable starting position,
• - externally induced movements of the device can be precisely controlled and reproduced,
• - Regular straight-line pendulum and swing exercises on movable Footprint with soft braking at the transition point,
• - Cycloid unwinding for counter-cyclical gyroscopic movements from almost stable weight point of the pelvis,
• - training against rotating swing weight,
• - Jumping and bouncing on foam or trampoline covering (in a horizontally fixed device).

to C Maximum freedom of movement requires the prone position, Hall) in severely disabled children) lying on your side, if necessary a four-legged stand or squatting position with the field of vision facing the ground.

Motion animations from this location are not known in any device of this type.

The above-mentioned shortcomings correspond to the task, by means of suitable simple shaping and Implement as many functions as possible with as few features as possible, especially

• - the safety of all data subjects, especially taking into account the Clinical picture and the disabilities, as far as possible and
• - All possible requirements for the coordination training of the movement animation of severely disabled people to demanding sports training lying down, Sitting, crouching, four-footed standing and standing with a basic device are sufficient.

Special design goals are formulated from this:
a support to keep a safety room free in the event of extreme tilting of the device between the peripheral rolling surface and the floor in any direction,
b sufficient widening of the edge (to prevent breakage when rolling over),
c elastic profile between rolling surface and floor (to prevent crush injuries when rolling over),
d all-round barrier (to prevent deep reaching under as far as possible),
e Keeping a horizontal area of the actuating area available in every tilt position of the device (to improve stability),
f automatic return of the device to a stable, central resting position under load (if the person performs incorrect movements, is tired or cramped),
g Central interactive position of the therapist on the device
h renouncing the stabilizing weight and minimizing the total weight (to avoid high leverage at the edge),
i minimizing the weight taking into account high tensile, bending and shear stresses when designing the device for 3 adults or several children,
j outer all-round guide and grip device,
k continuous rolling surface,
l mechanically clearly recognizable feedback control (to derive rhythmic movement harmonization),
m large central advertising space (use of the device as an interactive advertising medium), n executability of skill games,
o Simultaneous documentation of all self-induced and externally induced movements p Movement animation within a security room in the field of vision of the practicing (Kinesee-disturbed) child,
q Feasibility of complex movements:

• - linear lateral acceleration
• - Turn against eccentric weight
• - Cycloid unwinding with and without positive guidance (eccentric bearing)
• - trampoline jumping.

The construction goals a-q are completely satisfied by the joint training of Features according to title and the characteristic features according to main claim 1, secondary claims 2 and 3 and subclaims 4 to 25.

A self-supporting layer (c), comparable to a deformed plate, which may be a Sandwich interior structure is achieved through the integration of suitable coordinated waiters surface curvatures withstand high loads with regard to tensile, compressive, bending and shear stresses  low weight. You can easily in plastic vacuum forming, fiberglass or carbon fiber laminates and similar processes are produced.

The surface curvatures are formed by a spherical cap-shaped basic shape with a convex rolling surface a and a concave actuating surface b, an annular wall 1 , which forms a channel 2 on the opposite side, an annular concentric zone 3 within the wall with ribs 4 protruding from the operating surface and a wall Grip trough 5 concentric on the outside.

It is expedient for the flush finish of the upper wall and the ascending outer handle flank 6 and the wide design of the base underside b of the handle trough 5 as a form-fitting outer extension of the convex rolling surface a or as a flush extension in a truncated cone jacket.

The worked out in zone 3 , preferably radially or at right angles to these circularly arranged ribs 4 with an approximately triangular cross section, absorb tensile, compressive, bending and shear stresses, so that the radius of curvature of the spherical cap is so large and the center of gravity of the device is kept so low can be that the center of gravity always remains within the outermost support line when tilting. The channel 2 receives an elastic extruded profile 7 , which

• - Compressible and in the compressed state a security room d between the floor and peripheral rolling surface or the underside of the grip channel, so that fingers and toes can not be squeezed under
• - Enables the device to move due to increased friction on the surface (Application: acrobatic gymnastics).

Beyond the design goals

• - Raises the wall 1 a trampoline cover 19 so far that it can swing freely;
• - Secures the wall by radial depressions 18, the tensioning ropes of the covering, whereby
• - In the grip channel 5, the tension springs of the fabric are arranged sunk, whereby the training on the trampoline with regard to jumps in the edge area is better secured;
• - The channel 2 allows stable installation in a horizontal orientation on a substructure z. B. concrete ring;
• - protects the wall from falling out of children and toddlers;
• - the wall is a visible and tactile boundary of the interior;
• - the wall serves as a seat and stand for several people,
• - training the foot muscles or
• - As a neck support when lying on your back in the device;
• - The grip channel 5 secures the outside leading hand from injury due to the ergonomic inner grip;
• - This serves to absorb liquids and by means of scale rings 21 z. B. the horizontal setup of the device as well
• - The inclusion of molded parts, for. B. foam pillow;
• - gives the rib zone 3; 4 people sitting on the wall 1 or acting in the central area additional footrest 15 .

The design goal (mechanical feedback control to derive rhythmic movement harmonization) is achieved by the grip channel 5 , which serves as a runway for a rotating ball.

The ascending outer grip flank 6 can be profiled by machining itself or different profiles 17 can be placed on it. Punch, tooth and finger grip profiles are used to hold drives, measuring equipment, holding devices, even solution-safe clothing as well as the non-slip fine control of rotary movements and lateral accelerations from the outside.

For turning turns against a rotating eccentric weight, a 6-position trolley 20 with weight load is placed in the grip channel 5 . This carriage is adapted in cross section of the channel and guided against falling out in rails 17 .

The different requirements may require the staggered arrangement of the profiles.

Insert plates 8 of different cavities can be fitted overlying the rib zone in the wall ring. she

• - raise the center of gravity, with the coordination requirements grading can be increased wisely
• - Are sunk in the level of the rib zone, which improves the safety function of the wall preserved.

A special embodiment is a transparent insert plate 8 , which in conjunction with the rib zone, the wall and the concave inner field enables movement animations for severely disabled children. The child moves on the plate and looks through it at moving objects (spheres) that move in the inner field following gravity when the device moves. The wall prevents it from falling out, the ribs prevent the objects from getting caught and lock the plate, and the profiled grip channel enables the device movement to be guided safely from the outside.

Free z. B. on ball bearing cage sliding plates 9 allow approximately linear transverse accelerations from a safe position, with an externally controlled Kippbe movement allows the sliding plate to migrate to the lowest point, which retains the horizontal orientation, consequently leads to a parallel displacement from the solid floor . This linear movement applies to

• - Sensorimotor reaction tests e.g. B. in driving safety training and simulation;
• - Active actuation of the sliding plate z. B. in surf training;

In the transition to loop movements, there are pendulum swings; finally, cycloid unrolling can be carried out on the inner flank of the wall 1 without forced guidance by an eccentric.

The execution of the insert as a pickup plate 11 for turntables 10 in a centric and eccentric bearing enables the execution of further complex movements. With central storage of a turntable and peripheral support on roller bearings 12 there are combinations of movements, z. B. the obliquely balanced device partially runs on the extruded profile 7 .

The turntables have bearing bushes that are arranged at different distances from the center. In this round eccentric plates 13 are inserted, which roll in the resulting positive guidance on the inner flank of the wall, that is to say perform a self-rotation opposite to the total rotation (cycloid unrolling).

The ribs 4

• - give 8 non-rotatable fit in connection with the wall 1 ,
• - free-running balls and liquids serve as external guidance,
• - Provide sliding plates 9 with frictional edge support and, in the case of rib cross sections rising outwards in a wedge shape, decelerate transversely accelerated plates at the transition point (in front of the wall) and
• - Slip-free cycloid unrolling through counter-toothed eccentric plates 13 ; 14 generate.

There are no limits to the surface design. The concave interior can

• - serve as advertising space,
• - serve as a playing area for skill games,
• - serve as a relaxation island with upholstery cushions laid out over the wall,
• - serve as a play island for small children.
