The invention relates to a wood surface layer for a parquet and a method for manufacturing the same. A piece of fresh wood is cut in the cross-grain direction into slices or blocks which are carried through a microwave oven. Immediately downstream of the oven, as the slices or blocks are cooling, the surface thereof is coated with a water-soluble polyalcohol which impregnates in wood as a result of the action of a vacuum developing within the wood. The polyalcohol replaces some of the cell-wall water of wood and thus prevents the formation of seasoning cracks and the moisture induced movements in wood.

A telescopic tube, comprising a plurality of relatively sliding tube members (10, 11) fitted within each other. Along a major part (L.sub.0) of their length, the tube members are straight cylindrical tubes whose ends are provided with conical bulges (14, 15), so that one end is provided with an external cone (14) which diverges towards the end and the other end is provided with an internal cone (15) which converges towards the end. The latter end is surrounded by an external annular flange (16). The external and internal conical bulges (14) and (15) of individual tube members (10) and (11) are wedged against each other with friction engagement and keep the telescopic tube in the extended condition.

A post for an electric fence, comprising a straight stick portion (1), a base member (2) secured to the stick portion, and two plastic insulating members (3 and 4) disposed at a distance from each other. Stick portion (1) is made of reinforced plastic and base member (2) and insulating members (3 and 4) are manufactured straight upon the stick portion by injection moulding. All injection components (2, 3 and 4) are manufactured in one working step by one injection mould. After the manufacturing step, one (4) of the insulating members is displaced along the stick portion to its desired position. Base member (2) and the other insulating member (3) are fixedly mounted on said stick portion (1) by means of recesses or roughenings made therein.

Fastening means for the wrist strap of a ski stick, said means being positioned in a cavity (3) of the knob (2) of a stick handle (1). The fastening means is a removable unit separable from the stick knob and consisting of two plastic elements (5) and (7), between which said wrist strap (4) can be anchored as desired. The plastic elements are discrete elements within which the opposite ends of wrist strap (4) are embedded by molding. One (5) of the elements is anchored by profile locking (10, 11) in anchoring grooves (10) on the walls of cavity (3) in such a position that a wrist strap anchoring point (6) will be on the top face of said element. The other plastic element (7) is wedged into a downwards converging space between the wall of cavity (3) and the first plastic element (5) in such a position that another wrist strap anchoring point (8) will be on the lower face of the first element. The section of wrist strap (4) between plastic elements (5) and (7) is passed through between plastic elements (5) and (7). The abutting faces of plastic elements are jagged (15, 17). With said wrist strap (4) straightened out, said jagged faces (15, 17) of plastic elements (5, 7) face in the same direction. The fastening means is manufactured by passing a continuous strap material through the adjacent mold cavities of plastic elements (5, 7) and afterwards strap (4) is cut between plastic elements (5, 7).

A basket for a skipole, consisting of a periphery frame and a connecting piece between the pole and the periphery frame, said piece being an axle located in respect to the skiing direction crosswise, and being asymmetrically fastened to the rear of the said frame, said axle being of rubber or soft plastics called elastomer, and fastened without free play to said frame and said pole thus acting between these as an elastic torsion piece.

A wrist strap and buckle arrangement is constructed as a separately removable member to be contained within a cavity space formed in the handle of a ski pole. One end of the wrist strap is permanently secured in a frame portion of the buckle and the other end of the wrist strap is freely lockable as desired between a locking lever of the buckle and the frame portion. An intermediate portion of the wrist strap extends exteriorly of the handle through a slot leading from the cavity space. The wrist strap is free of any adjustment means therealong which could gall the hand of the skier. The buckle locking lever is positioned in the open end of the cavity space so that the adjustment operation is easy to carry out.

Buckle and strap and method for the manufacture thereof, especially hand

A handle for mounting directly on the upper end of a ski stick comprising a fitting element, a curved extension extending above the fitting element, the curved extension having a cavity space containing a buckle for longitudinally, adjustably fastening a wriststrap. An outlet for the wriststrap is in a convex side of the curved extension. The convex side extends up above the outlet to provide a relatively high face surface, the direction of the center axis of the curved extension forming an angle of between 15.degree. to 40.degree. with respect to the center line of the stick portion.

Ski stick handle

A disk for a skiing pole comprises a sleeve-like part, a peripheral main frame extending asymmetrically from said sleeve-like part, and a plurality of supporting lands integrally interconnecting the sleeve-like part and the main frame, whereby the lands and the main frame form a relatively rigid body located asymmetrically with respect to the sleeve-like part. The disk further comprises an auxiliary body including a plurality of attachment prongs engagable with the rigid body for removably attaching the auxiliary body to the rigid body, and an auxiliary frame portion at least partially laterally offset from the main frame when the prongs are so engaged for enlarging the bearing area of the disk.
