Definitions

  • the invention relates to a board structure of an ice hockey rink, which board structure has a board and a protective border and a rink side and a spectator stand side, which board consists of board elements connected together, each of which elements comprises a frame, which has vertical support posts and support pipes between these, and there are support posts only in the front part of the board i.e. in the rink side part, and in the upper part of the board element there is a U channel, and the protective border consists of transparent protective panels, which are attached in the U channel, whereby their lower part is inside the board element, and in the lower part of the board element there are one or more reinforcement pieces for supporting the board structure.
  • Ah ice hockey rink understandably requires sturdy boards around the ice area
  • the board should however be safe for the players, so that it causes as few injuries as possible in a physical contact game. Therefore the inner surface of the board is smooth and the aim is to make the board flexible, so that it bends a little, when a player drifts or is checked against the board. Additionally the entire board structure should protect spectators from pucks flying toward them, without having the visibility to the arena significantly suffer. Therefore the board is continued upwards with transparent protective plates, the height of which from the upper edge of the board is 1 m ⁇ 20 cm, in the end zones 1.6-2.0 m. The height of the board itself is about 1.2 m.
  • the stadiums where the ice hockey rink is placed, are often used also for other purposes than for playing ice hockey, such as for fairs and other recreational events.
  • Such use of the stadium requires a board structure, which may be dismantled, moved into storage and rebuilt.
  • the time between different events arranged in the same space may be relatively short. There may for example be a public concert between two ice hockey games arranged within half a week. Thus it is naturally advantageous if the rink can be removed and returned relatively quickly.
  • Tempered glass or acrylic plastic is usually used as material for the protective panels. Glass is durable and does not get scratched. Acrylic plastic is light and flexible. A disadvantage with glass is its weight and inflexibility and with acrylic plastic it is its susceptibility to scratching. It would often be useful to use different protective plate materials in different points in the protective border, but because their properties are so different, it would require two types of board structures, which would increase the cost of the protective border and make it more difficult to dismantle and assemble it.
  • Patent publication US 4905970 presents a board structure solution, which has identical board parts attached together and transparent protective panels on top of them, which panels are by their lower edge attached to the upper edge of the board part with a U-shaped groove structure. In the vertical direction the protective panels are supported to each other with an H-shaped post structure, which almost reaches the upper edge of the protective panel.
  • aluminium is presented as material for the groove structure and post structure and acrylic plastic as material for the transparent panel. If tempered glass is used as protective panel material in this solution, the post structure and board part must be made sturdy. With both material selections the post structure causes a visual obstruction, which may be an inconvenience for televising or photographing or for a spectator.
  • Patent publication WO 2009/056676 presents a board structure for an ice hockey rink, where the frame of the board elements has only one level, i.e. it has support posts only in the front part of the board, i.e. on the side toward the rink, the frames of adjacent elements are attached firmly to each other and their structural parts are relatively thin. Additionally the protective border is firmly attached to the board so that it cannot tilt in relation to the board. In the lower part of the board there are reinforcement pieces, which improve the strength of the frame and which extend to its rear side.
  • the board structure is in its entirety flexible, i.e. during a collision it bends over a relatively long distance of several elements.
  • the board structure is made light and flexible. Still, if it is desired to use tempered glass as protective panels in this solution, additional support structures must be added. Thus the one-level structure of the board element may suffer.
  • An object of the invention is a solution by which the drawbacks and disadvantages relating to the prior art can be considerably reduced.
  • the objects of the invention are obtained with a board structure of an ice hockey rink, which is characterised by what is presented in the independent claims. Some advantageous embodiments of the invention are presented in the dependent claims.
  • the basic idea of the invention is to form a board structure of an ice hockey rink, where a protective panel is placed in a U channel on top of a one-level board element and the bottom of the U channel is on the upper surface of support posts, whereby the support post supports the protective panel. There is an edge rail on both sides of the U channel, which further supports the protective panel.
  • the board structure of an ice hockey rink has a board and a protective border and a rink side and a spectator stand side, which board consists of board elements attached together.
  • the board elements each comprise a frame, which has vertical support posts and support pipes, and there are support posts only in the front part of the board, i.e. in the rink side, and there is a U channel in the upper part of the board element.
  • the protective border consists of transparent protective panels, which are attached in the U channel, whereby their lower part is inside the board element. In the lower part of the board element there are one or several reinforcement pieces for supporting the board structure.
  • the bottom of the U channel is supported on the upper surface of the support post or in a shape made in the upper surface of the support post, and the board structure has an edge rail on the rink side and an edge rail on the spectator stand side, which edge rails flank the protective panel in the U channel, and the rink side edge rail is rounded. Because the protective panels are supported by the U channel and the edge rails, the protective panels do not need fixed support posts between them.
  • the board element has a front wall, which consists of one or several superposed plates, and the frontal lower edge of the rink side edge rail extends over the upper edge of the front wall.
  • the rink side edge rail may be used as an attaching means for the front wall or its parts.
  • a second embodiment of the board structure of an ice hockey ring according to the invention there are pockets around the U channel, in which pockets there are tightening members, with which the protective panel in the U channel is arranged to be tightened into place.
  • pockets there are tightening members, with which the protective panel in the U channel is arranged to be tightened into place In a third embodiment of the board structure of an ice hockey rink according to the invention there are one or several upper support pieces in the upper part of the board element for supporting the U channel, the upper surface of which upper support piece is beneath the spectator stand side edge rail and the lower surface of the upper support piece is beneath the level of the bottom of the U channel.

  • adjacent protective panels are attached together with an H moulding, which is placed between the adjacent protective panels.
  • the height of the support post, the height of that part of the U channel which is above the level of the upper surface of the support post, and the thickness of the part of the edge rail which is on top of the upper edge of the board structure together form substantially the total height of the board structure.
  • the edge rail may be either one, the rink side edge rail or the spectator stand side edge rail.
  • the height of the support post is thus at least as much smaller than the height of the board structure as the height of the U channel or the height of the part of the U channel which is above the level of the upper surface of the support post, if the U channel is in a shape in the upper surface of the support post.
  • An advantage of the invention is that with its aid the support posts of the frame may be made smaller, whereby the elements are lighter and the material costs are decreased. Likewise with its aid the number of parts of the board structure may be reduced, which further decreases the manufacturing costs and makes the dismantling and assembling easier.
  • An advantage of the invention is further that this structure makes possible a solution, where the support posts between the protective panels are not needed.
  • the invention further makes the front rail smaller, whereby the risk of injury for the players is decreased.
