DETAILED DESCRIPTION OF THE INVENTION
[0052] The exploded view shown in FIG. 1 shows an embodiment of a skate blade 1 suitable for the sport of ice hockey in which the steel frame 11 and the blade holder elements 13-1, 13-2 are formed in one piece. The steel frame 11 shown in this embodiment has a blade thickness 15 of approximately 3 mm and extends along the longitudinal axis (see FIG. 2) in the positive x-direction between the curved first and second ends 1E, 2E. Furthermore, the steel frame 11 has two blade holder elements 13-1, 13-2 on the steel frame upper side 1421. The steel frame 11 shown in this embodiment further comprises, between the bottom chord and the upper chord, four struts 111 and five partition walls (see FIGS. 3 and 4) arranged between the side plane of the first side surface 1S and the side plane of the second side surface 2S as stability elements. In the embodiment shown in FIG. 1, the struts 111 are present with a strut width (see FIG. 3) as two straight lines extending substantially parallel to each other. Further, the struts 111 shown in this embodiment are arranged between the front section and the mid-section, between the mid-section and the rear section and in the mid-section (see FIG. 2). The struts 111 arranged between the front and mid-sections and the struts 111 arranged between the mid and rear sections each extend at an angle relative along an axis parallel to the vertical axis so as to ensure optimum transmission and distribution of the forces acting on the steel frame and the struts from the blade holder elements 13-1, 13-2. Furthermore, the two struts 111 arranged in the mid-section each extend at an angle relative along an axis parallel to the vertical axis such that additional stability of the steel frame is achieved. Ten recesses 112, each located between the first and second side planes of the first 1S and second 2S side surface and the partition wall, are formed by the stability elements included in this embodiment. The recesses 112 are triangular and quadrangular in shape with rounded corners, the geometry of the respective recesses 112 adapting to the geometry and design of the steel frame 11 of the skate blade 1. Furthermore, the recesses 112 are provided with insert elements 12 and the insert elements 12 are provided in a corresponding shape to the respective recesses 112. When inserted into the recesses 112, the insert elements 12 are flush with the first side surface 1S and the second side surface 2S, respectively, and thus do not protrude transversely beyond the blade thickness 15 of the steel frame 11.
[0053] FIG. 2 shows a view of the first side surface 1S of a skate blade 1 according to an embodiment of the invention. In addition, the division of the blade length 16 from the first 1E to the second 2E end into a front section 161, a mid-section 162 and a rear section 163 is shown, as well as the division of the blade height 14 into the bottom chord 141 and upper chord 142, wherein the bottom chord 141 includes a steel frame bottom side 1411 and the upper chord 142 includes a steel frame upper side 1421. These divisions are merely guidelines for the person skilled in the art and are not intended to define the exact boundaries of the areas.
[0054] FIG. 3 and FIG. 4 show a perspective view of a cross-section along the vertical axis through the mid-section (see FIG. 2) through the skate blade 1 shown in FIG. 1. The steel frame 11 has a blade thickness 15 of 3.0 mm. The partition walls 1121 present as stability elements in this embodiment are plane-parallel partition walls with a partition wall thickness of 0.5 mm each. The partition walls 1121 are arranged parallel between the first and second side planes of the first 1S and second 2S side surfaces, so that the resulting distance between the side planes, and the partition walls, and the resulting recesses have equidistant transverse depths. Furthermore, the recesses located in the first and second side planes are arranged symmetrically to each other.
[0055] FIG. 5 shows an embodiment of a skate blade 1 according to the invention for the sport of figure skating. The steel frame 11 shown in this embodiment includes a blade length 16 of 270 mm extending between the first 1E and second 2E ends, wherein the front section 161 is 40%, the mid-section 162 is 40% and the rear section 162 is 20% of the total blade length 16. The skate blade 1 shown further includes two blade holder elements 13-1, 13-2, which are arranged in the front section 161, to the boundary with the mid-section 162, and in the rear section 163, to the boundary with the mid-section 162, respectively, on the steel frame upper side. The first end 1E shown in this embodiment includes the jagged shape typical of figure skating. Furthermore, this embodiment includes further recesses formed by struts in the front 161 and rear 163 sections.
[0056] The embodiment according to the invention shown in FIG. 6 shows another skate blade 1 for the sport of ice hockey. The steel frame has a blade length 16 of 280 mm, with the front section 161 is 15%, the mid-section 70% and the rear section 15% of the total blade length 16. In addition to a blade holder element 13-1 in the front section 161 and a blade holder element 13-2 in the rear section 163 of the steel frame, the skate blade 1 has a further blade holder element 13-3 in the mid-section 162 of the steel frame. In addition, the blade holder elements 13-1, 13-2 and 13-3 have additional openings for weight reduction.
[0057] The embodiment according to the invention shown in FIG. 7 shows another skate blade 1 for the sport of bandy. The steel frame has a blade length 16 of 300 mm, with the front section 161 is 10%, the mid-section 75% and the rear section 15% of the total blade length 16. Further, the skate blade 1 has a blade holder element 13-1 in the front section 161 and a blade holder element 13-2 in the rear section of the steel frame.
[0058] The embodiment according to the invention shown in FIG. 8 shows another skate blade 1 for a goalie in the sport of ice hockey. The steel frame has a blade length 16 of 280 mm, with the front section 161 is 15%, the middle section 70% and the rear section 15% of the total blade length 16. In addition to a blade holder element 13-1 in the front section 161 and a blade holder element 13-2 in the rear section 163 of the steel frame, the skate blade 1 shown has a further blade holder element 13-3 in the mid-section 162 of the steel frame.
