Abstract
Abstract A compound aerial tram chair cover formed with one smaller shell and a second larger shell pivotable about a horizontal axis to extend over the smaller shell in opening. The pivotable mounting of the cover provides shock absorption upon extreme pivotable motion and from an offcenter position biases the movable shell to either closed or open positions. Means are provided to maintain the cover partially open to allow comfortable extension of a user''s legs. The cover provides a small reactive surface to wind pressure while providing a large contained volume for user comfort, and allows loading during carrier motion.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
164 words
For aerial tram carriers a spheroidal cover providing a passenger supporting seat structure and adapted for use with a suspension yoke having a lower U-shaped carrier supporting portion, comprising in combination: two pivot structures, each having laterally inner fastening disks and laterally outer journal elements structurally carried by each lower end of the suspension yoke; a frame depending from and communicating between the fastening disks of the opposed pivot structures: a hemispheroidal back cover structurally communicating for support at least with the frame, with an axis of revolution substantially through the pivot structures, rearwardly enclosing a seat structure to support passengers; and a shell-like, hemispheroidal forward cover with inside radius slightly greater than the outside radius of the back over and with annular fastening disks along a diameter substantially coincident with an axis of revolution, the fastening disks being journaled respectively upon the outer journal elements of the opposed pivot structures to mount the forward cover for pivotable opening motion over the rearward cover.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
31 words
The invention of claim 1 further characterized by: mechanical biasing means associated with at least one pivot structure to bias the forward cover from a medial position to an open position.
Claim 4
Dependent Claim
34 words
The invention of claim 1 further characterized by: shock absorbing means associated with at least one pivot structure to aid in lessening the inertia of motion of the forward cover in approaching extreme positions.
Claim 5
Dependent Claim
34 words
The invention of claim 1 further characterized by: a movable mounted spacer bar manually manipulatable to a position supporting the forward cover open a spaced distance from the lower edge of the rear cover.
Claim 6
Dependent Claim
45 words
The inventIon of claim 1 further characterized by: the hemispheroidal covers mounted with the planes of their greatest areas angling forwardly and downwardly relative the tram carrier to bias the forward cover to a closed position, with aid of gravity, as it approaches this position.
Claim 7
Dependent Claim
11 words
The invention of claim 1 wherein the hemispheroidal shapes comprise hemispheres.
Claim 8
Dependent Claim
100 words
In a compound, relatively movable aerial tram carrier cover, supported by a U-shaped depending yoke, the combination comprising: a hemispheroidal rear cover carried by the depending yoke along a substantially horizontal axis of revolution; passenger carrying means associated with the rear cover and carried substantially within the enclosed volume thereof; paired opposed pivot structures carried by the end parts of the depending yoke; and a forward hemispheroidal cover having internal radius slightly larger than the external radius of the rear cover, journaled along an axis of revolution on the opposed pivot structures for pivotable opening motion over the rear cover.
Claim 9
Dependent Claim
100 words

Claim 10
Dependent Claim
11 words
The invention of claim 7 wherein the hemispheroidal shapes are hemispherical.
