Abstract:
1. An impact absorbing telescoping post, comprising: a vertical hollow column; a post in axial alignment with said hollow column, said post having an external diameter slightly less than an internal diameter of said hollow column and being telescopically received within a hollow interior of said hollow column; a coil support plate secured to said hollow column in surmounting relation thereto; a coil spring disposed in surmounting relation to said coil support plate; a top plate secured to said post in surmounting relation thereto; an upper end of said coil spring secured to said top plate; a centrally apertured spacer plate disposed parallel to said top plate and spaced downwardly therefrom; a plurality of bolts disposed in interconnecting relation to said top plate and said spacer plate; whereby application of a downwardly directed force to said top plate causes said post to retract within said hollow column, compressing said coil spring; whereby said top plate and spacer plate maintain their spacing from one another and travel conjointly with said post as said post retracts; and whereby said coil spring restores said top plate and said spacer plate to their respective positions of repose when said downwardly directed force is removed.
