DESCRIPTION:
BRIEF SUMMARY
The present invention refers to a means for putting on therapeutic elastic stockings, having two open ends, that fits round the foot and can cover it, in the form of a slipper.
Therapeutic elastic stockings having two open ends, also called support stockings, are amongst others worn by sufferers from varicose veins or crural ulcers or in case of injuries such as contusions or sprains. The dimensions of such stockings have been choosen in such a way that the stockings, after putting them on, will have been stretched in circumferential direction, so that they apply a normal pressure upon the skin.
The stocking being put on, this normal pressure is still enlarged as a result of the elasticity in pulling direction taking place at the same time, especially on those places where the stockings is pulled over vaultings of the foot, such as the heel.
The power necessary for putting on the stocking being proportionate to the prevailing normal pressure and the coefficient of friction between the stocking and the foot, is therefore rather large.
Putting on a stocking having two open ends, to lower the friction between the therapeutic elastic stocking and the foot it is known e.g. from FR-A-788.477 that was published on Oct. 10, 1935 to use special socklets made of a material having an outer and inner surface of low friction, the friction of the inner surface preferably being somewhat higher than that of the outer surface. These socklets having more or less the form of a slipper, cover the foot at the upperside up to the instep and at the underside up to the heel and at the same time protect the stockings, being put on, against damage by toenails.
In order to cover the legs of the user with normal stockings or a panty and to wear shoes after putting on the therapeutic elastic stockings the socklet is removed by pulling it or by pulling a tab attached to it. To this end the therapeutic elastic stocking has an open toe allowing the socklet to be pulled off.
As one pulls off a normal sock, this goes without any effort by taking this sock at the upper edge and stripping it off the foot or by putting one's hand between the upper edge of the sock and the leg and stretching the sock a little bit in radial direction and then pushing it off the foot. Because the upper edge of the means as described above, after putting on the therapeutic elastic stocking, is covered by said stocking these actions cannot be practised here. Removing the means can only be effected by pulling its toe-part.
In this case on the one side the means is strongly subjected to the traction power, so that it should be made of firm slightly elastic material, while on the other hand, removing it the friction with the stocking as well as with the foot has to be overcome.
As besides the socklet sticks to the usually by perspiration damp foot, removing the means makes a rather great demand on a person's power. The pulling power is smallest when it is applied parallel to the foot, but many users are functionally limited to such a degree that they are not able to pull off the socklet parallel to the foot.
Usually they will pull the socklet or the tab attached to it towards themselves, such demanding a considerably greater effort. Besides the known socklets are of a rather stiff material, so that, especially when the therapeutic elastic stocking moves along the heel, it still costs a fairly great effort to pull this stocking over the foot while putting it on.
It is the object of the present invention to provide a means for putting on therapeutic elastic stockings having two open ends demanding considerably less power than the known means to put on these stockings and to remove the means.
According to the invention this is obtained by a means for putting on therapeutic elastic stockings having two open ends, that fits round the foot and can cover it, in the form of a slipper or in a similar form, which comprises at least on its outer side a surface of low friction and a lining (4) of supple material and having surfaces of low friction, said lining being partly attac
