Particular embodiments are configured for use at the edge of a glass viewing and shielding panel disposed atop the boards of a hockey rink, for example such edges typically found at the team bench of a conventional hockey rink. A shock absorbing system of the device is positioned so as not to reach beyond the plane of the glass into the area of play. ## Claims ### Claim 1 In combination with an upright panel mounted atop boards of a hockey rink that delimit a playing area thereof, a protective device for an edge of said panel, the device comprising: a bracket mounted at or on the edge of the panel; an upstanding engagement member equal or similar in height to the panel, the engagement member being supported in a position placing an outer face of the engagement member in an orientation facing away from said edge of the panel at a distance spaced therefrom in a lengthwise direction of the boards; and a shock absorbing system located between the bracket and the outer face of the engagement member and being compressible in a longitudinal impact direction that is parallel to a flat upright plane of the panel and parallel to the lengthwise direction of the boards, whereby the shock absorbing system is arranged to absorb against the outer face of the engagement member in the longitudinal impact direction; wherein the shock absorbing system is free of any component or portion that extends beyond the flat upright plane of the panel into the playing area of the hockey rink. ### Claim 2 (depends on 1) The device according to claim 1 wherein the engagement member comprises a body of resilient material and the shock absorbing system includes at least one spring inside said body of resilient material. ### Claim 3 (depends on 2) The device according to claim 2 wherein said spring is a gas spring. ### Claim 4 (depends on 3) The device according to claim 3 wherein said gas spring is received in a respective hole located in the body of resilient material. ### Claim 5 (depends on 3) The device according to claim 3 wherein the gas spring compresses by allowing air to escape and re-expands by resilience in a wall of the spring acting to re-inflate the spring and return the expelled air. ### Claim 6 (depends on 1) The device according to claim 1 wherein the panel lies entirety in the flat upright plane. ### Claim 7 (depends on 1) The device according to claim 1 wherein the edge of the panel is curved out of the flat upright plane and the bracket is mounted on a convex side of the curved edge. ### Claim 8 (depends on 2) The device according to claim 2 comprising a flexible cover situated over the resilient body and the shock absorbing system, wherein the flexible cover is transparent and the at least one spring is formed from a transparent material. ### Claim 9 (depends on 1) The device according to claim 1 wherein the engagement member comprises a body of resilient material having an upright slot therein in which the bracket is received, whereby the resilient body embraces opposing sides of said bracket. ### Claim 10 In combination with upright glass mounted atop boards of a hockey rink that delimit a playing area thereof, a protective device for use thereon, the device comprising: a bracket mounted at or on an edge of a sheet of said upright glass of the hockey rink; an upstanding elongate engagement member generally parallel to the bracket and equal or similar to the glass in height, the engagement member being supported in a position placing an outer face of the engagement member in an orientation facing away from said edge of the glass at a distance spaced therefrom in a lengthwise direction of the boards; and a shock absorbing system located between the bracket and the outer face of the engagement member and being compressible in a longitudinal impact direction that is parallel to a flat upright plane of the glass and parallel to the lengthwise direction of the boards, whereby the shock absorbing system is arranged to absorb impact against the outer face of the engagement member in the longitudinal impact direction; wherein the shock absorbing system is free of any component or portion that extends beyond the flat upright plane of the glass into the playing area of the hockey rink. ### Claim 11 (depends on 10) The device according to claim 10 wherein the engagement member comprises a body of resilient material having an upright slot therein in which the edge of the sheet of said upright glass is received, whereby the resilient body embraces opposing sides of said upright glass. ### Claim 12 (depends on 10) The device according to claim 10 wherein the engagement member comprises a body of resilient material and the shock absorbing system includes at least one spring inside said body of resilient material. ### Claim 13 (depends on 12) The device according to claim 12 wherein said spring is a gas spring. ### Claim 14 (depends on 13) The device according to claim 13 wherein said gas spring is received in a respective hole located in the body of resilient material. ### Claim 15 (depends on 13) The device according to claim 13 wherein the gas spring compresses by allowing air to escape and re-expands by resilience in a wall of the spring acting to re-inflate the spring and return the expelled air. ### Claim 16 (depends on 10) The device according to claim 10 wherein the glass lies entirety in the flat upright plane. ### Claim 17 (depends on 10) The device according to claim 10 wherein the edge of the glass is curved out of the flat upright plane and the bracket is mounted on a convex side of the curved edge. ### Claim 18 (depends on 12) The device according to claim 12 comprising a flexible cover situated over the resilient body and the shock absorbing system, wherein the flexible cover is transparent and the at least one spring is formed from a transparent material.
