IMPACT ABSORBING DASHERBOARD

摘要

Disclosed is a dasher-boards assembly with capability to absorb impacts of players crashing into the boards. The glass pane surmounting the boards can tip away from the ice, against a spring, and then resiliently return to its normal (upright) position. The spring is a bar-spring, which not only is deflectable to provide the resilience, but also has the capability to support and position the pane with respect to the dasher-board. The bar-spring can be used when the pane is flush-mounted with respect to the dasher-board, or when the pane is set-back from the ice-side of the dasher-board.

主权项

1. Dasher-board for use with a glass pane, to form a dasher-board assembly, wherein:
the dasher-board includes a flexible bar-spring, which is so arranged in the dasher-board as to be free to undergo significant deflection from an unstressed condition to a stressed condition, and to resiliently return to its unstressed condition; upper and lower node-abutments are formed in a frame of the dasher-board; the node-abutments interact with the bar-spring to constrain upper and lower node-points of the bar-spring from undergoing translational movement in a horizontal sense relative to the frame; the bar-spring is so mounted and arranged in the dasher-board that:
(a) a between-nodes-length of the bar-spring is free to undergo bow-mode deflection movement relative to the frame;(b) an above-upper-node-length of the bar-spring is free to undergo tipping or rocking deflection movement relative to the frame; the dasher-board includes a pane-carrier, which is fast to the above-upper-node-length of the bar-spring; the dasher-board is so structured:
(a) that the pane-carrier has the capability to receive a glass pane;(b) that, a pane having been received in the pane-carrier, the pane and the pane-carrier are free to undergo substantial tipping or rocking movement relative to the frame of the dasher-board, but only in unison with each other; and(c) that such tipping or rocking movement of the pane and pane-carrier is accompanied by significant deflection of the bar-spring between its unstressed and stressed conditions.
