Abstract
This chair-lift cab for telpher lines has its seat protected by a shell pivoted about a transverse axis close to its center of gravity, at the front end of a bow pivoted in turn about another transverse axis at the rear of the first axis and close to the center of gravity of the bow and shell assembly, the upper portion of the shell being connected laterally to the frame structure of the chair-lift by means of arms pivoted at their ends, so that the space in front of the seat is cleared when the shell is tipped to its open position as a consequence of its double rotation about the two transverse axes, thus providing a balancing action insensible to gravity and dynamic forces.
Claims4
A chair-lift cab, for a telpher line, comprising:
- (i) a hanger
- (ii) a seat frame suspended from said hanger and including a pair of spaced supports,
- (iii) a seat integral with said seat frame and positioned with one of said supports at each side of the seat,
- (iv) a supporting bow rearwardly encompassing said seat and including a pair of lateral arms each of which is pivotably connected to a respective one of said supports for pivoting of the bow about a first pivot axis, each said lateral arm including a portion thereof projecting forwardly of said first pivot axis,
- (v) a rigid protection shell disposed in front of said seat and connected by pivot means to said forwardly projecting portions for pivoting of said shell about a transverse axis adjacent to its centre of gravity,
- (vi) a pair of coupling arms disposed one at each side of said shell, each coupling arm having one end pivotably connected to a respective support for movement about a second pivot axis, each coupling arm having its other end pivotably connected to an upper part of the protection shell,
- whereby the shell is movable between an opened position, in which it is moved away from the front of the seat to permit ingress and exiting of passengers, and a closed position in which it forms with the seat a closed housing, the rotation of the supporting bow through a given angle in the direction to open the shell resulting in rotation of the shell through a greater angle such that ingress and exiting of passengers, and fitting of cabs one into another for storage, are facilitated.
