Description

The present invention relates to a movement trainer for people with shortened extremities, in particular with a device for short people whose hip mobility is severely restricted.

Movement trainers for the disabled are well known in the art. The publication DE 20 3007 014 460 U1 shows, for example, a device for movement therapy, which has a support frame with a walk-through opening through which the patient arrives at an adjustable saddle which fixes the patient on the device by means of an adjustable back support. The movement takes place by means of the hand crank in the front area of the device. Furthermore, from the DE 198 11 233 A1 a training device for movement-impaired people has become known, which has a crank on which pedals are arranged with which the disabled person moves a motor-driven transmission, the movement type and intensity can be set electronically. Furthermore, in the publication DE 202 03 680 U1 discloses a multifunctional trainer, which represents a combination between a bicycle trainer and an elliptical trainer. This multifunctional trainer has, among other things, a crank mechanism, above which a bicycle saddle is arranged, on which a normal person can take a seat to actuate the crank mechanism.

It is perceived as a disadvantage of these known devices and movement trainers that they are not or only to a limited extent suitable for short people, whose extremities are generally very short and therefore have to make special demands on the design of a movement trainer.

Another disadvantage of the known training devices is that they can generally only be used by people in an upright position and people with restricted hip mobility are almost excluded.

It is therefore an object of the present invention to eliminate the disadvantages mentioned above and to provide a movement trainer for strengthening the disabled body which is simple and effective to use.

This object is achieved with the characterizing features of the main claim.

Further features according to the invention can be found in the subclaims and the description.

The device according to the invention for strengthening the extremities of a short body of a person or a person with restricted hip mobility with at least one seat surface and at least one movable lever arm, which is mechanically operatively connected to at least one crank mechanism, is characterized in that the connecting line between the pivot point of the hip joint of the body of the user of the device and the center of gravity of the seat surface and the center of the crank mechanism with minor deviations is arranged approximately on one axis.

It is advantageous that at least one bearing of the crank mechanism is arranged substantially below the seat.

It is also advantageous that the connecting line between the pivot point of the hip joint of the user's body and the center point of the axis of rotation of the crank mechanism describes the shortest path.

It is also advantageous that the slight deviations from the straight connecting line should not exceed the order of magnitude of approximately + 5%.

Another advantage is seen in the fact that at least one bearing is arranged in the center of the crank mechanism essentially below the seat surface.

It is considered advantageous that the deviation of the angle α between the ideal vertical connecting line ( 15 ) and the actual connecting line ( 15 ' ) from the vertical is between +/- 7 °, preferably between 2 ° - 3 °.

It is also felt to be advantageous that the angle α can be variably adjusted. It is also advantageous that the distances between the individual components for movement therapy can be adjusted in length by means of rods.

It is also advantageous that the length of the at least one crank is adjustable.

Another advantage is that the crank interacts with a mechanism whose rotational resistance is adjustable.

Another advantage is that at least two cross members are arranged transversely to the longitudinal axis of the movement trainer, of which at least one cross member has a larger diameter than the other cross members.

It is particularly advantageous that the at least one display of an ergometer is arranged in the front area of the movement trainer.

An important advantage of the present invention is that a crank mechanism for moving the arms and hands is arranged instead of a handlebar-like linkage.

It is also advantageous that a rotatably mounted and flat-shaped pedal is arranged at the end of the lever.

Another advantage is that the seat is designed as a bicycle-like saddle, preferably as a wide saddle.

It is also advantageous that a weight is arranged below the tread of the pedals.

Overall, it is advantageous that the device according to the invention can be built in a modular design.

Another advantage is seen in the fact that the seat on which the user sits can be moved and adjusted horizontally.

The 1 shows a schematic side view of the device 1 with a gear, not shown here, in a housing 2 that is below a seat 3 is arranged. The housing 2 is part of the frame, which consists of a plurality of individual adjustable components that are ergonomically arranged to each other. With that in the case 2 arranged gear, the load or the power to be applied is set and measured. The housing 2 is with a traverse 4 connected, which is round and tubular in the present embodiment as a mainstay. At a predetermined distance a from the traverse 4 is another traverse 4 ' arranged as a second pillar, both together for the stability of the device 1 to care. The diameter of the rear crossbeam 4 is larger than the diameter of the front crossmember 4 ' , Outside the case 2 is in the front of the case 2 a crank mechanism 10 arranged from a disc-shaped element 5 exists, to which via a lever arm 6 a flat trained pedals 7 is attached. The crank mechanism 10 , with which the invisible gear is driven, is described in more detail. The middle-point 12 of the crank mechanism 10 lies approximately vertically below the center of gravity S of the seat 3 , which can be designed in different embodiments, e.g. B. bicycle saddle-like or riding saddle-like or elongated or round, which essentially depends on the anatomy of the user. The distance between the center 12 and the seat center of gravity S depends on the length of the legs of the user and is with an actuator 13 set that can be constructed in various designs, for example as a pipe in pipe displacement, with a locking element 14 , which is designed as a screw. In the normal case of the present invention, the axis forms 15 the connection between the center point 12 and seat 3 and the horizontal an angle of 90 °. In practice, however, this angle can deviate from the ideal case. The deviation from the vertical angle is between α approximately +/- 7 °, preferably approximately 3 °, depending on the anatomical requirements of the patient. In the front upper area of the housing 2 is a strut 17 arranged whose length with an actuator 18 and a locking element 19 can be adjusted according to the individual needs of the user. To this strut 17 is another strut 20 arranged at a predetermined angle, preferably 90 °, also with an actuator 21 and a locking element 22 is adjustable. With the struts pointing forward and upwards 17 . 20 , as well as a possible further strut 23 is the individual desired distance of the body 11 the user to a handlebar-like facility 24 and the display 25 of the ergometer adjustable, which ensures optimal effectiveness of the device according to the invention. The steering wheel-like device 24 has at least one handle at a given point 26 on which further levers (not shown here) for setting the device in the broadest sense can be carried out, for example the loading parameters or the display values. In a special embodiment, the handlebar-like device 24 can also be exchanged with a crank mechanism 24 ' to operate the user's arms and hands.

The 2 shows a schematic side view of the crank mechanism 10 as a drive for a gearbox within the housing 2 the device 1 , The crank mechanism 10 is outside the case 2 arranged and consists essentially of a disc-shaped element 5 , on at least one lever arm 6 is adjustable. The longitudinal axis of the lever arm 6 points towards the center 12 of the crank mechanism, which is also the center of the disc element 5 is to the lever arm 6 a flat trained pedals 7 is adjustably attached. Below the flat pedals 7 sits a weight 8th , which is connected to the bearing shell of the pivot bearing of the pedals, so that the center of gravity of the entire pedals 7 outside the axis of rotation 9 the pedals 7 is arranged. This causes the flat tread of the pedals 7 always points upwards, so that the user always has the climbable step surface of the pedals 7 finds. The length of the lever arm 6 is adjustable and depends, among other things, on the flexibility of the user's hip joint. The adjustability of the lever arm 6 is by means of an actuator 27 achieved that can be realized in different ways, e.g. B. with a locking screw on the disc-shaped element 5 along the longitudinal axis of the lever arm 5 ,

In summary, it should be noted that with the present invention an apparatus 1 is presented, which is suitable for the training of the extremities of a short body, as well as a body of a person with restricted hip mobility. The user of the device 1 sits on a seat 3 , about which the position of the hip joint of the user is arranged, the fulcrum D of the hip joint, the focus S the seat 3 and the center 12 of the crank mechanism 10 on the straight axis 15 between the center of gravity of the seat S and center point 12 the axis of rotation of a crank mechanism 10 is arranged, so on the shortest connection between the pivot point D and the center 12 the axis of rotation of the crank mechanism 10 , whereby the deviation of the shortest connection can vary within certain limits. The device 1 can therefore be used in any position of the user, either sitting or lying down or in an intermediate position.
