Description

SHORT DESCRIPTION OF THE DRAWING

(1) FIG. 1 shows a drawing in perspective of the invention comprising a training apparatus for disabled persons.

(2) FIG. 2 shows an alternative embodiment of the device according to the invention where the device is not motorised.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(3) With reference to FIG. 1, a detailed description of a motorised training apparatus for disabled persons will be given according to the invention. The whole apparatus is mounted on a skid, with a detailing which follows the reference numerals of FIG. 1. The skid carries at least one pivotable disc, for example two discs 1,2, which are connected to a shaft for rotation around a centre of rotation. To the disc(s) 1,2 are connected two rails in the form of eccentric bars 3. The eccentric bars 3 run from the disc(s) 1,2 to a slip connection at the skid, such that the bars in one embodiment can translatory slide horizontally into the skid, and at the same time can be moved vertically by the eccentric disc(s) 1,2. The bars 3 are running under the seating device (described above) and are equipped with fastening devices for the user's feet. By fastening the feet to the bars 3, the feet will be moved in a controllable manner with the bars 3, in the relevant movement pattern. The disc(s) 1,2 are run by a motor as mentioned above. It will be possible to run the disc(s) 1,2 to rotation around their own axis of rotation, in which case the device functions as a motorised ellipse machine. Alternatively it may be possible to fasten the bars 3, in the skid of the device, at the same time as the disc(s) 1,2 are equipped with grooves in the form of arc segments with the centre in the foremost fastening point for the bars 3. When operating the disc(s) 1,2, the movement of the bars will, in this embodiment, be more as a stair step movement. An alternative can be to operate the disc(s) 1,2 by a lever movement, which will, when the bars 3 slide into the frame, give a skiing-like movement of the bars 3. It will also be possible to disconnect the discs 1,2 from each other, such that they can be operated individually. This can for example make a skiing movement, where it is suitable that the bars 3 are not being lifted too much in the vertical direction during operation of the device, to be obtained. In such a movement, the discs 1,2 will move alternately back and forth in relation to one another.

(4) To carry out the elliptical movement, two eccentric discs 1,2 are applied, which may be connected to a common shaft. Each of the eccentric discs has an attachment of eccentric bar 3, which can be fastened in different holes with different distances from the centre of the eccentric disc, in order to change the stroke of the walking movement. By fastening the eccentric bars 3 near the axis of rotation for the discs 1,2, a less horizontal, as well as vertical, movement of the bars 3 will be obtained, while fastening into fastening points (for example holes) further away from the axis of rotation for the discs 1,2, will provide a larger stroke of the bars 3, both in a horizontal and vertical direction, and consequently larger steps for the patient.

(5) The invention, being the muscular-driven as well as the motorised version, can be applied by a user who utilises all positions from a seated to a standing position. The apparatus can therefore be equipped with a device for serving of the position of the parallelogram, which constitutes the arrangement for seating and erection, in the device according to the invention. Such a device can for example be a pneumatic spring 4, with a lock providing continuous adjustment from the seated to a standing position. The pneumatic spring 4 works on the parallelogram, which the seating device and corrective rail are attached to. Alternatively, or in addition, the up-and-down guiding movement of the parallelogram can be operated manually with a handle. It may also be possible to serve the position of the parallelogram and the seat/support for the lumbar region with other forms of operating devices, such as a gear with a spindle operation (worm gear). It can of course also be possible to operate the piston 4 for serving the seat/support for the lumbar region with the aid of hydraulics as well as pneumatics.

(6) In the motorised version of the device according to the invention, the eccentric discs 1,2 receive power from a motor, which preferably is electrical. In one embodiment, the eccentric disc 2 is operated from a connection to the eccentric disc 1. When the connection is released, the eccentric discs may rotate independently from each other, such that both eccentric bars can be placed in a horizontal position. It would be desirable that the rotational displacement between the eccentric disc 1 and the eccentric disc 2 is 180, such that this provides a natural walking movement. This is also related to the operation of the stiffening system for the lower leg/knee, explained below (and indicated previously), since the forward movement of one bar 3 will be connected to the backward directed movement of the other bar in the device, via an elastic band/strap/spring which coordinates the user's leg movements.

(7) As a part of the seating/standing arrangement, a bar 6 is used, forming a parallelogram such that the backbone always is vertical. In this connection, the seating height of the seat in the parallelogram can also be adapted for persons of different height, from children to adults. In order to adjust the height according to the user, a knee joint 7 is provided which can be adjusted in the height. Similarly, a hip joint 8 is provided, in which the distance to the knee joint can be adjusted for adaptation to the user. Thus the relative distance between the hip joint and the knee joint will be larger if the device is adapted to an adult person, compared to if the device is used for a child. It is preferred that such a seating/standing arrangement exists in the form of a parallelogram, but other embodiments can also be possible, such as a sickle form, which ensures that erection by stretching in the hips and support to the knees can be secured in the same way as for a parallelogram.

(8) For adaptation to the back of the user, the apparatus according to the invention includes a back column 9 for the attachment of a back support 10. The back column 9 is, in the shown embodiment of the device, a vertical bar running from the hip joint support to the patient's neck. However, it will be possible to make this column 9 longer, for example in order to stiffen the neck and head of a person who has, for example, been subject to a neck injury, whereby it is important for the person who is injured to keep the head at rest during training. In such cases, the column 9 will also be equipped with fastening devices for neck and head (in addition to fastening means for the user's chest area). The back column 9 is fastened to the support for the back 10 with the aid of transitions, which can be adjusted in the height of the column 9 for adaptation to the user's height. In connection with the support for the back 10, lateral supports 11 are also provided, which can be pivoted out and which constitute a chest support, such that the user's upper part of the body is fastened in use. The chest support corrects the upper part of the body and, with the seating pillow 12 with lateral supports, this constitutes an integral unit which secures the user in all ways and keeps the person in an upright position in use. Since the back/chest support is hinged in the hip joint, the back/chest support will not move considerably (if at all) when the user is moved from a seated to an upright position.

(9) After fastening of an elastic band/spring, strap, bar device 14 (as explained above), to compensate for lack of muscles in the legs, the user can now be raised to a standing position with the aid of a pneumatic spring, a hydraulic spring or a mechanical device, such as by worm operation, manual operation or by electrical operation. In the muscular-operated version of the device it will be relevant to carry out this erectional function manually, even though alternatively in one embodiment it can be driven electrically. When the user is in upright position, he is standing in a corrected and proper standing position provided by the fastening 16 to the lower part of the leg, the hip fastening 8 and the back/chest fastening 10. The elastic band device 14 runs from the hoop 16 for the lower part of the leg, and around for example the roller behind the seat, and has the important function that it shall prevent the user from collapsing in his legs. Further, the elastic band device 14 ensures a natural and necessary stretching of the muscles at the back side of the legs, since the elastic band 14 will stretch the leg backwards with the forward movement of the other leg and vice versa, and ensures that an alternate muscular contraction and muscular stretching will arise when operating the device.

(10) In order to, in the motorised version of the device according to the invention, secure the legs, an adjustable hinge point 15 is provided for the ankle which has a connection with the hoop for the lower part of the leg 16, with the bar in order to keep the leg in the correct position. Additionally, a hoop 17 is provided for fastening of the foot to the foot support member 23. The hoop is locked with an eccentric locking 18, for hoop to foot.

(11) One embodiment of the invention has also included a releasing unit 19 for brake-on-gas dampening, and a button 20 for the adjustment of the rpm of the motor.

(12) At the same height as the arm there is provided a table top, or other extra equipment 21, which is pivoted to one side when there is no use for it.

(13) The invention also comprises a tightening device 13 for elastic band 14, which rolls against a pinching disk in order to give the correct tightening throughout the whole bar cyclus. The other end of the eccentric bar 3 is arranged with wheels inserted in a rail device for steering the horizontal movement of the eccentric bar. The inserted wheel of the eccentric bar 3 will, in a skiing and walking movement (elliptic movement), be led horizontally back and forth in its groove in the rail device. If, however, as explained above, it should be desirable with a stair step movement in the device, the wheel on the eccentric bar may be locked to the rail device. If this embodiment of the operation is desirable, the driving wheels 1,2 are equipped with grooves, such that operation of the wheels 1,2 will then force the rails 3 up and down vertically, since the horizontal movement is now locked in that the foremost wheel is now locked in the sliprail. If the driving wheels 1,2 can be pivoted back and forth, a stairstep movement may be provided in that it is not then necessary with grooves for the rail 3, which runs around the whole wheel, but only needs to constitute a part of a circle with the centre in the fastening point for the inserted wheel.

(14) When the user has been raised and is standing in a correct and proper standing position, in the motorised version of the device according to the invention, the motor is started with a speed which can be continuously or gradually adjusted. The user will then be forced to move the legs with the aid of the motor power at the same time as stretching is ensured owing to the elastic band device.

(15) A device as explained above could be made for many different types of disablement, from completely paralysed persons to persons who have mobility, but who need to train coordination and development of correct patterns of movement for walking. It will therefore be possible to construct it with controllers for pneumatic and electrical motor, which can be served by the patient himself, up until embodiments where such attendance is left to the nurse. An advantage with the device according to the present invention is that it saves on space and work. It can be handled either by the patient himself (and thereby liberate workforce so that nursing personnel can do other tasks) or by one nurse only, where previously it was necessary with up to several nurses in order to ensure that the patient moved naturally and correctly.

(16) As mentioned above, the device according to the invention may also work for persons who are handicapped in movement (in contrast to persons who are movement able, see above), that is persons who for one reason or another have unusual motor function in the legs and/or in the body. Examples of such unusual motor functions are also mentioned above, and may comprise persons who are ill (Parkinson's disease, poliomyelitis, spastic diseases, muscular atrophy, etc.) persons who are injured (for example neck/back injuries in traffic injuries, fractural injuries such as femur fractures, hip joint fractures, tibia/fibular fractures, fractures in the foot etc.). For such persons it may be relevant not to carry out the relevant movement completely with a motor, but the motor can, as the treatment of the disease/injury improves the state of the patient, be successively disconnected in that it, during a time period, can be run as an assisting motor.

(17) In an alternative embodiment, it may also be possible to equip the skid for the device with wheels such that it can move around in its environment. When the device according to the invention is run as a stationary training apparatus, the bars 3 will be moved in a distance from the underlay. By, for example, forming the skid for the device with vertical telescoping parts, it will be possible to lower the bars 3 such that they reach the under layer. By additionally equipping the skid with wheels, it will be possible to move the whole device around in its environment, either by operation of the motor (in which case the wheels may be equipped with a steering arrangement in which the user can steer the position of the device), or by operation with muscular power.

(18) In a muscular-operated version of the relevant device, only the leg support, hip support and back support can be present together with the leg support, which will comprise of the withdrawal devices for the knees, as explained above (see FIG. 2).

(19) The material of the device, according to the invention, is not of significance, but it may be desirable that it is of light weight and requires little space. Thus, a suitable material for the device may be aluminium or aluminium alloy, even though another metal may also be used, such as steel or a steel alloy for the wearing parts of the device. Also hard plastics may be used, in particular for the parts which support the body of the patient (chest strap, leg straps, foot straps).
