摘要： An artificial skiing surface comprising a plurality of single elements formed from plastic adapted to be detachably joined together in side-by-side relationship including a base layer provided with a plurality of flexible upwardly extending plastic fingers and a plurality of sockets in each of which rotatable balls are disposed formed from plastic having a hardness greater than that of the fingers and having the same height as that of the fingers together with a guidance comb inserted in a groove in the base layer and having flexible teeth with globular tips which extend upwardly preferably to a height above that of the fingers to provide control of a ski sliding thereon.

摘要： The change head (1) for a tool change apparatus is provided at its free end with a prism-shaped centering opening (15) and in the center thereof an axially displaceable screw driver (3). Arranged concentrically with respect thereto is a screwthreaded sleeve (9) which has a female screwthread and which is mounted slidably but non-rotatably in an axial bore (8) in the head (1) and which is urged towards the centering opening (15) by a spring (14). A respective radially displaceable clamping member (12) is provided in each of two radially extending bores (11) in the screwthreaded sleeve (9), the two radial ends of each clamping member being cones (12a, 12b) (or hemispheres). Axially movably arranged in the screwthreaded sleeve (9) is a clamping sleeve (13) which extends with its one (outer) end (13a) into the core bore of the female screwthread (10) and has a frustoconical portion (16) which co-operates with the radially inner ends (12a) of the clamping members (12) and which increases in diameter towards the outer end (13a). Provided in the wall (1b) of the bore of the head (1), in the region of the clamping members (12, 12'), is at least one inclined surface (18) which is inclined towards the free end (1a) of the head and the axis (A) of the screwthreaded sleeve (9) and against which the radially outer ends (12b) of the clamping members (12) bear.
