Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
A car, notably of a funicular railway, having a chassis running above a track laid along a slope having a gradient, and a compartment disposed on said chassis, said compartment having a longitudinal symmetry plane parallel to a longitudinal axis of the track, as well as a floor and a roof, said chassis comprising a hanger arm having a free end and a central articulation spindle supported by said free end to which said compartment is suspended, said central articulation spindle extending perpendicularly to said longitudinal plane to allow free movement of the compartment in said longitudinal plane and to hold the floor in a horizontal position independently from the gradient being climbed by the car.
Claim 2
Dependent Claim
116 words
A car, notably of a funicular railway, having a chassis running above a track laid along a slope having a gradient, and a compartment disposed on said chassis, said compartment having a longitudinal symmetry plane parallel to a longitudinal axis of the track, as well as a floor and a roof, said chassis comprising a hanger arm having a free end and a central articulation spindle supported by said free end to which said compartment is suspended, said central articulation spindle extending perpendicularly to said longitudinal plane to allow free movement of the compartment in said longitudinal plane and to hold the floor in a horizontal position independently from the gradient being climbed by the car.
Claim 3
Dependent Claim
44 words
A car according the claim 1, wherein said hanger arm is disposed in said longitudinal plane, said floor having an opening in the form of a slit or longitudinal groove extending through the compartment of the car, said hanger arm passing through said opening.
Claim 4
Dependent Claim
24 words
A car according to claim 2, wherein said compartment comprises an internal housing bounding the movement area of the hanger arm inside the car.
Claim 5
Dependent Claim
48 words
A car according to claim 1, wherein said compartment suspension spindle is located at the level of the roof at a height from said chassis to leave between the chassis and the floor, in the horizontal position of the car, a sufficient space "d" to clear the compartment.
Claim 6
Dependent Claim
58 words
A car according to claim 1, wherein said hanger arm is formed by a straight pole appreciably perpendicular to said chassis, and fixed to the chassis at a fixing point, said fixing point being offset towards an uphill side of the chassis, the term uphill being defined in relation to the gradient of the slope of the track.
Claim 7
Dependent Claim
56 words
A car according to claim 1, wherein said hanger arm is swan-necked in shape with a convex part facing towards the uphill side of the chassis, the term uphill being defined in relation to the slope of a track, the fixing point of the swan-neck hanger arm to the chassis being offset towards a uphill side.
Claim 8
Dependent Claim
32 words
A car according to claim 6, wherein said compartment comprises on the uphill side a groove disposed in the longitudinal symmetry plane, said hanger arm passing through and moving in said groove.
Claim 9
Dependent Claim
65 words
A car according to claim 1, comprising a motor, notably a hydraulic jack means, fitted between the chassis and the compartment and a control device of said motor to swivel the compartment in relation to the chassis when a variation in the inclination of the chassis occurs when the car is travelling along the track and to keep the floor of the compartment appreciably horizontal.
Claim 10
Dependent Claim
28 words
A car according to claim 8, comprising a safety device to automatically put said motor out of operation when the inclination of the compartment exceeds a preset threshold.
Claim 11
Dependent Claim
42 words
A car according to claim 1, wherein said chassis comprises a carriage which runs on a railway being hauled by a hauling rope, said compartment comprising loading and unloading openings located on a face of the compartment parallel to said longitudinal plane.
