DESCRIPTION OF THE EMBODIMENTS

[0018] FIG. 1 presents a diagrammatic and simplified view of one border element 1 according to the aspects of the disclosed embodiments as viewed obliquely from the front. The border element 1 comprises a frame 2, which is preferably a ring-shaped structure with top bars 3a, bottom bars 3b and the end bars 3 connecting these. There can be more than one top bar and more than one bottom bar in a single border element 1. A plurality of display panels 4a forming a digital display 4, such as a LED display, are suspended on the frame 2.

[0019] Preferably the height of one display panel 4a is essentially equal to the height of the whole display area of the border element 1. In addition, the display elements 4b of the display panels 4a are adapted to be fastened to each other at their end edges, in which case there is no gap between the display elements 4b in the assembly of border elements 1 disturbing the information displayed by the display elements 4b, except for special border elements, such as e.g. border elements comprising opening gates, in which small gaps are possible at the point of the gates. Preferably the total combined width of the display elements 4b is equal to the distance of the outer surfaces of the end bars 3 of the border element 1 from each other. In this case, e.g. the video image to be displayed on the inside of the border of an ice hockey rink is continuous and can move around the border from one dasher board 1 to another seamlessly.

[0020] In FIG. 1, the protective sheet 1a protecting the display elements 4b is missing from the front of the display elements 4b, which protective sheet is placed in front of the display 4 in the finished structure and fastened e.g. by riveting to the frontmost top and bottom bar 3a, 3b of the frame 2 between the frontmost bottom bar 3b and the front plate 18. The protective sheet 1a shown in FIGS. 2, 5 and 7 is a clear and transparent sheet suitable for the purpose, such as e.g. an acrylic or polycarbonate sheet.

[0021] FIGS. 2 and 3 present a diagrammatic and simplified view of one dasher board 1 according to the invention as viewed from the rear, in other words e.g. as viewed from outside the ice hockey rink. FIG. 2 presents an oblique rear view from above of the border element 1, and FIG. 3 presents an oblique rear view from above of an enlarged detail of one end of one border element 1 according to the invention, with the top and bottom suspensions of the display panels 4a.

[0022] Each display panel 4a comprises a support frame 6, which is, in turn, fastened by means of suspension means 7 to an essentially horizontal support rod 8 in the upper part of the border element 1. The side edges of the support frame 6 are bent backwards at right angles to the front surface of the support frame 6 in such a way that the side edges form the fastening surfaces for adjacent support frames 6. The support frame 6, with the outer surfaces of its side edges, is preferably as wide as the display element 4b fastened to the front side of the support frame 6, i.e. the distance between the outer surfaces of the side edges equals the width of the display element 4b. Thus, adjacent display panels 4a are easy to fasten seamlessly to each other. When the support frame 6 is as wide as the display element 4b, adjacent display panels 4a can easily be fastened to each other with tightened fastening means 12, such as screws and nuts, in the fixing holes in the side edges of the support frame 6. The front surface and the front side refer to that side on which the image of the display element 4 is visible. The rear side is the opposite side.

[0023] The distance between the outer surfaces of the side edges of the support frame 6 can also be smaller than the width of the display element 4b. In this case, a filler of a suitable thickness, e.g. one or more washers or a shim, can be placed between the outer surfaces of the side edges of the support frames 6 of adjacent display panels 4a in conjunction with the fastening.

[0024] The suspension means 7 of the upper end of the display panel 1 can be e.g. a flat bar fabricated into a suitable shape and bent, which bar advantageously keeps the upper end of the display panel 4a in position. The support rod 8 is placed in the upper part of the frame 2 of the border element 1 between the end bars 3 of the border element 1. At both ends of the support rod 8, or near its ends, is one shock absorber means 11, which is preferably disposed between the support rod 8 and the top bar 3a of the border element 1, to absorb horizontal and upward directed forces caused by a possible impact on the display element 4b. Preferably there is a shock absorber means 11 only on both ends of the support rod 8, so that one border element 1 only has two units of them, one at each end.

[0025] Correspondingly, the display panels 4a are supported at their lower part by a horizontal strut rod 9, each end of which is adapted to be supported by a second shock absorber 13 below the strut rod 9, the shock absorber being supported on a support means 14 fastened to the end bar 3 of the frame. Preferably the strut rod 9 is circular in its cross-section, e.g. a round tube. The lower part of the display panels 4a comprises two support means 10 extending backwards from the display panel 4a and fastened to the support frame 6 near its side edges. The lower edge of the support means 10 is provided with a round upwardly curved support surface, the radius of curvature of which is the same or greater than the radius of the outer surface of the strut rod 9, and which support surface is adapted to rest on the top surface of the strut rod 9. By virtue of the shape of its support surface, the support means 10 are adapted to prevent movement in the front-rear direction of the lower part of the display panels 4a as well as the downward movement of the display panels 4a.

[0026] Due to the circular cross-section of the strut rod 9 and the curved supporting surface of the support means 10, the display panel 4a is easy and quick to fasten into position when installing it and, if necessary, to detach. When detaching, for example, it is sufficient to detach only the suspension means 7 of the upper end from the support rod 8, in which case the display panel 4a can be turned backwards at its upper end around the strut rod 9 and lifted out of its position. Installation of a display panel into its position is performed in the reverse sequence.

[0027] Since the support means 10 is not fastened to the strut rod 9, the display panel 4a can, if necessary, also be moved sideways on the strut rod 9. This also facilitates and speeds up the installation and, if necessary, the replacement of e.g. a faulty display panel 4a.

[0028] FIG. 4 presents one display panel 4a to be used in a border element 1 according to the invention, as viewed obliquely from the rear, without the support frame 6 and components fastened to it. A display panel 4a comprises, inter alia, a display element 4b, on the front side 4c of which is a display surface and on the rear side of which is an electronics unit 5 with control unit and control system.

[0029] FIG. 5 presents a partly simplified view of a magnified detail of an end of one border element 1 according to the invention, as viewed in the direction of the arrows along the section line A-A of FIG. 7. The figure clearly shows that the outer surface of the side edge 6a of the support frame 6, the side edge of the display element 4b, the side edge of the protective sheet 1a and the outer surface of the end bar 3 are all on the same straight line, i.e. on the same vertical plane in the operating position of the border element 1. This enables an essentially unitary display surface, on which the moving information flow can be seamlessly presented. The outer surface of the end bar 3 is the surface that faces the corresponding outer surface of the end bar of the adjacent border element 1. Correspondingly, the side edge of the display element 4b and the side edge of the protective sheet 1a are those edges that face the corresponding edges of the adjacent border element 1.

[0030] FIGS. 6 and 7 present a diagrammatic and simplified view of one end bar 3 of the frame 2 of a border element 1 according to the invention and a border element 1 as viewed from the end. FIG. 6 presents just an end bar 3 and FIG. 7 presents a view of a border element 1 provided with display panels 4a, a protective sheet 1a and other components, wherein the end bar 3 is partially sectioned at its upper end.

[0031] Preferably the end bar 3 is fabricated from metal, by cutting and welding from steel plate, and by reinforcing the bar by bending the edges of the blank into a right angle with the end surface to be formed. In this case the bends of the end bars 3 in a finished frame 2 face each other.

[0032] On the front edge of both end bars 3 of the frame, in other words e.g. when a dasher board 1 is part of an ice hockey rink on the edge inside the rink, is a recess 15 extending from the front edge of the end bar 3 towards the rear edge, for situating the outermost side edges of the edgemost display panels 4a in the dasher board 1 on the same vertical plane as the outer surface of the end bar 3. The height of the recess 15 is then greater than, or equal to, the maximum height of the display panel 4a and the depth is dimensioned in such a way that there is an air gap 16 between the display surface on the front side 4c of the display element 4b and the protective sheet 1a in front of it. This air gap 16 both cools the display 4 and improves the impact resistance of the display element 4b because the distance of the front surface of the display element 4b to the surface of the protective sheet 1a increases. In this case even a hard impact on the protective sheet 1a does not bend the protective sheet 1a so much as to collide with the display surface of the display element 4b.

[0033] The basic color of the front surface of the display elements 4b and the display panels 4a is preferably white or light and arranged to operate in such a way that the points where the light sources of the display are not, at a certain moment, active appear white or light in the display. This improves e.g. the visual contrast of the black puck against the dasher board in hockey play.

[0034] It is obvious to the person skilled in the art that different embodiments of the invention are not limited to the example described above, but that they may be varied within the scope of the claims presented below. Thus, for example, the structure of the border elements can also be different than what is described above.

[0035] It is also obvious to the person skilled in the art that there can be display panels and/or display elements in one border element also one above another in addition to just one beside another, or both one above another and one beside another. It is also possible that there is only one display element, the area of the display surface of which covers the whole display area.
