Abstract

A transparent, shatter-resistant glass shield for mounting atop the dasher board of a hockey rink includes at least one glass panel. A glass-retaining plastic film is adhered to a surface of each glass panel. The plastic film substantially covers the surface. An edge retainer may be mounted on at least one edge of the glass panel.

Claims

1. A method for forming a protective barrier for a hockey rink, the method comprising:

forming a glass shield, including;

(a) providing a glass panel suited for mounting atop a hockey rink dasher board and having a front surface, a back surface, and top and side edges;

(b) removing a substantial portion of any surface dirt or particles from the back surface;

(c) ensuring that the back surface is substantially dry;

(d) providing a plastic film having one or more plastic layers and having substantially clear optical procedures;

(e) adhering the plastic film sheet to the back side of the glass;

(f) providing transparent retainer channel portions sized and shaped to fit substantially along the top and sides of the glass panel; and

(g) assembling the retainer channel portions along the top and side edges of the glass panel such that the channel portions overlap the plastic film;

(h) wherein the plastic film comprises a plastic film having one or more plastic layers, an adhesive layer and a release liner, and the step of adhering the plastic film comprises;

wetting the back surface of the glass panel with an aqueous solution;

removing the release liner from the plastic sheet;

applying the plastic film to the back surface, so that the adhesive layer contacts and bonds to the back surface;

forcing a substantial portion of the aqueous solution out from between the back surface and plastic film; and

allowing the plastic film and back surface to dry.

2. The method of claim 1 further including mounting the glass shield on a rim of a dasher board.

3. A protective barrier for a hockey rink, said protective barrier comprising at least one transparent, shatter-resistant glass shield, the glass shield including:

(a) at least one glass panel, wherein each glass panel has a front surface, a back surface, and a plurality of edges, at least one of the plurality of edges being a free, top edge;

(b) a glass-retaining plastic film adhered to a surface of each glass panel, wherein the plastic film substantially covers the surface;

(c) at least one edge retainer engaged on the free, top edge of each glass panel, wherein each edge retainer extends over substantially the full length of the free, top edge and overlaps the plastic film along the free, top edge, wherein the plastic film and edge retainers on a panel assist in the retention of a substantial portion of broken glass after breakage of that glass panel; and

(d) a dasher board having a top rim, wherein the glass shield is mounted on the top rim of the dasher board;

(e) wherein;

each glass panel has opposed side edges and a bottom edge;

the at least one edge retainer engages and extends over substantially the full length of each of the side edges; and

the bottom edge is disposed within the top rim of the dasher board.

4. The protective barrier of claim 3 wherein the at least one edge retainer is formed of polyvinyl chloride (PVC).

5. The protective barrier of claim 4 wherein the at least one edge retainer is transparent.

6. The protective barrier of claim 3 wherein the at least one edge retainer includes a channel having a U-shaped cross-section and engages each of the front and back surfaces of the glass panel.

7. The protective barrier of claim 3 wherein the at least one edge retainer is transparent.

8. The protective barrier of claim 3 wherein the plastic film has a thickness of about 0.014 inch.

9. A protective barrier for a hockey rink, said protective barrier comprising:

(a) a dasher board having a top rim;

(b) at least one transparent, shatter-resistant glass shield mounted on the top rim of the dasher board, the glass shield including;

at least one glass panel; and

a glass-retaining plastic film adhered to a surface of each glass panel,

wherein the plastic film substantially covers the surface; and

(c) at least one edge retainer engaged on an edge of each glass panel;

(d) wherein the glass panels are rectangular and the plurality of edges of each glass panel includes a top edge and first and second side edges; and

(e) wherein a first edge retainer is engaged on the top edge, a second edge retainer is engaged on the first side edge, and a third edge retainer is engaged on the second side edge of the glass panels.

10. The protective barrier of claim 9 wherein the plastic film has a thickness of about 0.014 inch.

11. The protective barrier of claim 10 wherein the plastic film is comprised of a plurality of plastic layers.

12. The protective barrier of claim 9 wherein each glass panel is tempered glass.

13. The protective barrier of claim 9 wherein the plastic film further comprises a scratch resistant coating adjacent to the plastic layer.

14. The protective barrier of claim 9 wherein the plastic film is adhered to the back surface of each glass panel.

15. The protective barrier of claim 14 wherein at least one additional plastic film is applied to at least a portion of the front surface of each glass panel.

16. The protective barrier of claim 9 wherein each glass panel further includes a first ½

-inch radiused corner between the top edge and the first side edge, and a second ½

-inch radiused corner between the top edge and the second side edge, wherein the first and second beveled corners assist in mounting the glass shield around a hockey rink.

17. The protective barrier of claim 9 wherein the edge retainers are channels having a U-shaped cross-section.

18. The protective barrier of claim 9 wherein the edge retainers are substantially transparent.

19. The protective barrier of claim 9 wherein the edge retainers are constructed of polyvinyl chloride.

20. The protective barrier of claim 9 wherein the edge retainers are adhered to the glass panel and plastic film along the engaged edges of the glass panels.

21. The protective barrier of claim 9 wherein each glass panel has a free, top edge and at least one of the edge retainers is engaged on the free, top edges of each glass panel.

22. The protective barrier of claim 9 wherein each of the edge retainers extends over substantially the full length of the respective edge of the glass panels.

23. A protective barrier for a hockey rink, said protective barrier comprising:

(a) a dasher board having a top rim;

(b) at least one transparent, shatter-resistant glass shield mounted on the top rim of the dasher board, the glass shield including;

at least one glass panel; and

a glass-retaining plastic film adhered to a surface of each glass panel,

wherein the plastic film substantially covers the surface; and

(c) wherein each of the glass panels has a thickness of about one-half inch.

24. The protective barrier of claim 23 wherein each glass panel is tempered glass.

25. The protective barrier of claim 23 wherein the plastic film further comprises a scratch resistant coating adjacent to the plastic layer.

26. The protective barrier of claim 23 wherein the plastic film is adhered to the back surface of each glass panel.

27. The protective barrier of claim 26 wherein at least one additional plastic film is applied to at least a portion of the front surface of each glass panel.
