<p>Board structure for an ice-hockey rink especially for halls where it has to be disassembled and reassembled repeatedly. The board structure is made in its entirety flexible so that it in impact yields at a relatively long distance, of several elements. This is realised by that the frame of the board elements (300) is only in one plane, in other words it has support posts (311) only in the front part of the board, or on the part facing the arena, the frames of the adjacent elements are fastened tightly to each other and their structural parts are relatively thin. Furthermore the shield border (400) is rigidly fastened to the board so that it cannot incline in relation to the board. In the lower part of the board there are reinforcement blocks (321) extending to the rear part of it and improving the frame strength. The rear wall of the board consists of the plates detachable without instruments. The lightness, flexibility and strength are combined in the board structure. The sufficient strength is obtained by that, for reasons mentioned above, the impact force is distributed over a relatively long distance in horizontal direction and over the whole height of the board structure in vertical direction. The structure can be disassembled, stored and reassembled relatively quickly.</p> |
