Abstract
Abstract A cable conveyance having a storage region for garaging the carriers whichan be decoupled from the transport cable. The carriers are displaced along a transport rail to the storage regions by a reversible drive and are permitted to move by gravity along storage rails into this region or by positively tilting these storage rails back to the transport rail to return to the cable. Thus within the storage region the displacement of the carriers is by gravity only and there is no need to provide a special drive for entrainment of the carriers along the storage rails.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
238 words
A cable conveyance, comprising: a cable transporter having a transport cable, guide means for defining a path for said cable, drive means for displacing said cable, a plurality of carriers couplable to and decouplable from said cable, and a guide rail receiving carriers decoupled from said cable for disembarking and boarding of passengers and returning decoupled carriers to said cable for recoupling thereto; and means for garaging of said carriers, said means for garaging of said carriers including: means forming a storage region for receiving carriers to be garaged, a transport rail between said guide rail and said region and a drive associated with said transport rail for advancing carriers from said guide rail to said region, at least one storage rail in said region having an end turned toward said transport rail and receiving said carriers therefrom and an opposite end remote from said transport rail, means for mounting said storage rail to enable it to swing about a substantially horizontal axis between a position in which said storage rail is inclined downwardly away from said transport rail and said carriers move onto said storage rail by gravity and a position in which said storage rail is inclined downwardly toward said transport rail and said carriers move toward said transport rail by gravity, and means connected with said drive for reversing same to advance carriers from said storage rail to said guide rail along said transport rail.
Claim 2
Dependent Claim
238 words
A cable conveyance, comprising: a cable transporter having a transport cable, guide means for defining a path for said cable, drive means for displacing said cable, a plurality of carriers couplable to and decouplable from said cable, and a guide rail receiving carriers decoupled from said cable for disembarking and boarding of passengers and returning decoupled carriers to said cable for recoupling thereto; and means for garaging of said carriers, said means for garaging of said carriers including: means forming a storage region for receiving carriers to be garaged, a transport rail between said guide rail and said region and a drive associated with said transport rail for advancing carriers from said guide rail to said region, at least one storage rail in said region having an end turned toward said transport rail and receiving said carriers therefrom and an opposite end remote from said transport rail, means for mounting said storage rail to enable it to swing about a substantially horizontal axis between a position in which said storage rail is inclined downwardly away from said transport rail and said carriers move onto said storage rail by gravity and a position in which said storage rail is inclined downwardly toward said transport rail and said carriers move toward said transport rail by gravity, and means connected with said drive for reversing same to advance carriers from said storage rail to said guide rail along said transport rail.
Claim 3
Dependent Claim
44 words
The cable conveyance defined in claim 1 wherein said storage region is provided with a plurality of storage rails and for n storage rails in said region, from 1 to n-1 branches are provided to selectively connect said storage rails to said transport rail.
Claim 4
Dependent Claim
37 words
The cable conveyance defined in claim 2, further comprising a respective actuator connected to each of said storage rails at said opposite end thereof remote from said transport rail for shifting said storage rail between said positions.
Claim 5
Dependent Claim
25 words
The cable conveyance defined in claim 3 wherein each of said actuators includes a fluid-operated cylinder and a piston articulated to the respective storage rail.
Claim 6
Dependent Claim
38 words
The cable conveyance defined in claim 4 wherein said means for mounting includes means forming a hinge joint having a substantially horizontal axis for the respective end of each of said storage rails turned toward said transport rail.
Claim 7
Dependent Claim
30 words
The cable conveyance defined in claim 5 wherein said drive is a conveyor chain having entrainment fingers projecting therefrom and displaceable along said transport rail for engagement with said carriers.
Claim 8
Dependent Claim
43 words
The cable conveyance defined in claim 6 wherein said means connected with said drive is operatively connected with said drive means for displacing said cable for reversing the direction of said cable substantially contemporaneously with reversing a direction of displacement of said drive.
Claim 9
Dependent Claim
35 words
The cable conveyance defined in claim 7 wherein each of said branches includes a device having a pair of branch tracks rotatable about an axis and selectively alignable with respective ones of said storage rails.
Claim 10
Dependent Claim
18 words
The cable conveyance defined in claim 8 wherein said chairs and said cable conveyance is a chair lift.
Claim 11
Dependent Claim
19 words
The cable conveyance defined in claim 8 wherein said cars and said cable conveyance is a cable car apparatus.
