BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a traction device intended to be fastened on an extremity of a person or an animal suffering from joint trouble, in order to eliminate or mitigate the troubles. The device comprises a base material on which a number of pockets are arranged, which pockets are intended to carry a varying number of weights. Further, holding means, necessary for the fastening on to the extremity, are permanently attached to the device.
A weight device is previously known through the U.S. Pat. No. 4,303,239. This device, which includes large and bulky weights, is intended to be fastened on the thigh of a person and to be used for the training of the musculature of the thigh. In order to prevent the device from slipping down on the leg, it is equipped with a waist-belt which is coupled to the weight device. However, the known device cannot possibly bring about any traction in the joint of the extremity of the person in question.
Through the U.S. Pat. No. 2,241,833 is further an exercising device previously known. This device, which also comprises large, bulky weights, is intended to be applied on the forearm or the shank of a person, so that the person in question, through raising and lowering of the extremities, may be able to train the arm and leg musculature. This device is thus only intended to be put on the extremity or extremities of the person in question during training. Accordingly it is not intended or suited for the traction of the joint in an extremity. Moreover, the known device is difficult to put on and take off, inasmuch as it has to be fastened with a lace on two sides. Besides, the base material of the exercising device is not made to extend around the whole of the extremity. This means that the number of pockets must be limited and the weights in the pockets have to be made large and bulky, which in turn results in that the device becomes extraordinarily clumsy.
SUMMARY OF THE INVENTION
In contrast to the known devices, the principal object of the present invention is to provide possibilities for the attainment of a continuous traction in the joint in that extremity of a person onto which the present device has been fastened, for instance in the hip-joint of a person who has hip-joint troubles. Furthermore, the present device is so designed that it in a flexible way and without tendency of slipping down will be able to fit tight around the extremity, whereby the person in question will be able to carry his or her traction device inside the trousers or inside the shirt. This has been made possible through the bringing about of a traction device of the to start with mentioned kind, which is characterized by, that the base material extends around principally the whole of the extremity, that the pockets are placed at regular distance from each other around principally the whole of the device, that the pockets have the shape of an oblong, downwards narrowing parallel-trapezium and have a direction, which is principally perpendicular to the longitudinal direction of the device. One or more thin weights having a shape, which corresponds to the shape of the pockets, are intended to be put into each pocket. In this way, the device will function as a traction device for the extremity, so that a continuous traction arises in the joint of the extremity, Moreover, through its arc-shaped longsides of unequal lengths the device acquires such a shape that it in a flexible way fits tight around the extremity, whereby it does not become space-requiring but can be accomodated inside the shirt, the sweater or the trousers on a person.
