Definitions

• the present invention relates to a training aid for the treatment of strabismus and/or defects in the. motory function of the eye. It is a principle object of the invention to provide a training aid of the kind mentioned above, which is of a simple design and comprises few components and moreover is simple to use.
• a training aid which is substantially characterized by a path of movement, which is intended to be compulsorily followed by a hand of a person, exhibiting means of indication, and actuating means, which can be connected with said indication means in order to sense said path, while the indication means and the hand are displaced along the path, whereby said connection brings about the forward feed of the indicating means along the path and/or indicates deviations from the path of movement.
• Fig. 1 is a perspective view of a training aid designed according to the invention.
• Fig. 2 shows the training aid in a side elevational and partly sectional view.
• a disc 1 which at its periphery supports a magnetic body 2, is rotatably supported by a shaft 3.
• This shaft 3 is provided with a gear 4, which via two worm gears 5 and 6 can be driven by means of a battery-operated motor 7.
• the motor 7 is in its turn supported by one end portion of a long base 8, which by way of example is adapted to be supported by one hand of a person.
• the other end of this base supports a counter device 9, the cooperation of which with the disc 1 will be explained later.
• Batteries for the operation of the motor 7 are enclosed in the centre portion 10 of the long base.
• a counterweight 11 is provided on the disc on. the other side of the centre shaft 3 right in fron of the magnetic body 2.
• actuating means 15 can comprise a contact 15, which is closed by magnetic actuation.
• the base 8 and the disc 1 are enclosed in a box-like casing 16, which is provided with supporting feet 17 in order to make possible that the device can be supported by way of example on a table.
• the device can also be designed in such a way that the disc 1 will extend in a vertical plane, and the whole device can also be mounted in such a manner that the disc will be pivoted on a determined shaft in a reciprocating movement.
• An edge 18 is formed at the top of the casing 16 whereby the peripherical edge la of the disc 1 is protecte against touch, so that the disc 1 cannot be caused to rotate by manipulation of the edge of the disc.
• the function of the training aid described above which is in the first place intended for training o simultaneous movements of the eyes and the hand of the person, will now be described more in detail.
• the counter device 9 is set to zero by means of the push button 1 ⁇ , after the disc 1 has been rotated in such a manner that th magnetic body has stopped right above the indicating senso 20 of the counter device 9.
• the contact 15 is gripped by the person, which shall utilize the training aid, and by moving the contact 15 towards the disc 1 to the space righ above the magnetic body 2 the contact 15 is closed, whereb current from the batteries is conducted to the driving motor 7, which in its turn brings the disc 1 to rotate.
• Alternative designs of the training aid can be made by arranging a fixed path, along which a body or similar can be forced to displace itself by the movements of the hand of the person.
• the path can by way of example comprise a light sensoring means, which senses a movable light-beam generator, for example a photoelectric cell device and is actuated by the same.
• a counter device can then be arranged to sense the deviations of the hand and the light-beam generator from the path of movement.
