发明名称 REMOVABLE RAIL SEAL
摘要 A rail seal for sealing the gap between a rail and the surrounding surface material in a rail crossing or track construction, wherein the rail seal is removable from the gap and can be re-installed in the gap without damaging the surrounding surface material. More particularly, the rail seal is formed with an integral hinge element that has a closed position and an open position wherein an upper portion of the rail seal is released from and extends upwardly away from a lower portion of the seal body thereby imparting additional flexibility to the seal body. To remove the rail seal from the gap adjacent the rail, the rail seal can be manipulated so as to be pulled free from the gap. In order to re-install the rail seal, the additional flexibility provided by the hinge element allows the rail seal to be manipulated and deformed as required so as to be reinstalled within the open gap. The rail seal may also be formed with anchor recesses at opposed ends of the rail seal body for receiving anchoring keys which help to secure the rail seal within the gap so as to prevent longitudinal movement and shifting of the rail seal over time.
