Frame for supporting device for coupling e.g. ski or skate frame which is slidable or rollable by wheels to shoe - has resetting spring, and upper and lower sub-frames mutually pivotable and translatable to main plane

摘要

The frame comprises an upper sub-frame with a device for coupling to a shoe to be worn by a user. A lower sub-frame is coupled via a pivot mechanism to the upper sub-frame for pivoting in a main plane. The lower sub-frame is provided with or adapted to be provided with a runner or wheels. A resetting spring is provided for urging both sub-frames toward each other. The frame has the special feature that the sub-frames are mutually pivotable and translatable in the main plane. The sub-frames may form part of a mechanism comprising at least four mutually pivotable and/or translatable rods.
