Abstract: The invention relates to a blade for an indoor bandy stick, comprising a top-edge reinforcing rib (5), a bottom-edge reinforcing rib (6) and therebetween a number of reinforcing ribs (7, 9) which lie lengthwise of the blade and are spaced from each other so as to form open spaces between the lengthwise ribs (5, 6, 7, 9). The interspace between the mid-section reinforcing ribs (7) is located at the distance of a radius (D/2) of a ball (3) from the bottom edge of a blade (12). Thus, the ball hits the reinforcing ribs at more than one point along the ball surface. One or both sides of the blade can be concave.

Abstract: The invention relates to a pole shaft for a cross-country ski pole. Longitudinal and transverse fiber layers are used for providing a hollow shaft, whose cross section changes progressively downwards into a droplet shape and, below the mid-way point of a shaft, the length of a droplet shape in relation to its width increases while the cross-sectional area diminishes. By virtue of the droplet shape, the pole can be given more rigidity in skiing direction, whereby the bottom end of a pole can be made lighter while improving the aerodynamics of a pole.

Abstract: A shaft for an indoor bandy stick, comprising a hollow tube. The tube has a substantially circular bottom end which turns elliptical when progressing upwards while the tube expands conically. The ellipse has a major axis (a) which at its maximum is at least about 15%, preferably about 30% longer than its minor axis and the conicity is such that the diameter of the ellipse parallel to the major axis (a) increases at least about 30%, preferably about 50% or more and the diameter parallel to the minor axis (b) increases 0-30%.

Abstract: The invention relates to a method for measuring the deflection in a golf club shaft (3) for controlling the dynamic loft angle of a shaft. The method comprises the steps of fixedly clamping a shaft (3) at a certain distance from a club head (5), setting club head (5) in vibration, and measuring the vibration frequency while shaft (3) is clamped at the clamping distance. This is followed by releasing the shaft (3) from clamping and by repeating the above actions at varying distances from the club head (5) and by using the thus obtained measuring results for setting up a frequency profile for shaft (3).

Abstract: The object of the invention is a free technique ski pole comprising a pole stick (2), to the lower end of which is rigidly fixed by sleeve-like fitting (5) a plastic snow disc (3), near the front edge (8, 9) of which is a spike-fastening sleeve (6) to which the spike (7) is fastened. In free technique skiing the pole is in a sideways inclined position during pushing. The spike's hold is thus improved and the support of the snow disc's bearing surface on the ground becomes more even, when looking from the front, the direction of the longitudinal axis of the pole stick forms an angle of about 5.degree.-15.degree. with respect to the direction of the spike (7). Correspondingly, the snow disc edge (10) on the side of the skier is positioned higher and the bearing surface (12) connected to it forms a smaller angle with respect to the horizontal plane than the outer side edge (11) of the snow disc and the bearing surface (13) connected to it.

Abstract: A method for forming a joint between a product formed of composite material including reinforcing fibers and a connecting piece includes forming the connecting piece with a shoulder within a joint region thereof and during the formation of the product, guiding the longitudinally extending reinforcing fibers of the composite material as continuous, unitary fibers through a first path within the joint region of the connecting piece toward the connecting piece shoulder, around the shoulder of the connecting piece, and then in a substantially opposite direction through a second path within the joint region of the connecting piece to return to the composite material of the product, whereby both the product of composite material and the joint between the product and the connecting piece are formed simultaneously.
