Abstract:
An height adjustable crosswalk apparatus comprising a pair of vertically upright telescoping platform towers spaced horizontally from one another, an horizontally elongated crosswalk having opposing ends with horizontal rods mounted in their opposed ends, said horizontally elongated cross walk extending generally horizontal in length with one end adjacent the top of one of the towers and the other end adjacent the top of the other of the towers, the towers each having a horizontal platform mounted to their tops, pair of turntables each having a horizontal base panel with a vertical yoke rotatably mounted to the base panel and extending upward therefrom to rotate about a vertical axis, said base panels of said turntables having a size approximating the size of the top platforms of the towers to overly the tower platforms with means at the outer edges of the turntable base panels securing the turntable base panels to the outer edges of the top platforms of the towers, means on the towers to individually raise and lower the towers whereby the cross walk may pivot upward at one end at angle from horizontal in relation to its other end, when the tower at the one end of the crosswalk is telescoped vertically above the tower at the other end of the crosswalk by the crosswalk pivoting on the horizontal rods which is connected to the yokes of the turntables, and whereby the towers may be moved horizontally from one another to move the crosswalk at an angle horizontally from its previous position with the yokes of turntables pivoting about their spaced vertical axes to their mountings to the turntable base panels.
