2. Description of the Related Art In recent years, cableway equipment for transporting passengers using a chair-type carrier has been made of a material such as transparent resin for the purpose of protecting passengers from wind and snow while moving along the cableway. Some windshields are formed so as to be pivotable up and down. The windshield swings up and down to open and close between a position covering passengers and seats and a retreat position opening the front of the passengers.
A detailed structure of the windshield opening / closing operation or opening / closing operation is disclosed in Japanese Patent Application Laid-Open No. 2-77355, entitled "Skilift Windshield Opening / Closing Apparatus" filed on Sep. 14, 1988 by the same applicant as the present application. It is shown.

[0003] That is, as shown in FIG. 11, in the conventional “windbreak opening / closing device for a ski lift”, a suspender 40 is suspended from a suspension pin 4 of a towing machine, and a carrier is attached to a lower end of the suspender 40. A windshield opening / closing device 60 is attached to the suspender 40. In the windshield opening and closing device 60, a plate-shaped lever bracket 61 is fixed to the suspender 40 with bolts or the like. A swivel shaft 65 is fixedly extended to the lever bracket 61, and a swivel lever 62 having a roller 63 rotatably pivoted at the end thereof swings in the vertical direction of an arrow 68 or an arrow 69 via a roller shaft 64. It is pivotally connected. One end of the remote cable 42 is pivotally connected to the roller shaft 64 of the turning lever 62.
The other end of the remote cable 42 is pivotally attached to a bracket (not shown) on the windshield.

[0004] Rollers 6 are provided along the rails for the carriage to travel at the stops at the top and the bottom of the foot where passengers get on and off.
An open rail (not shown) and a closed rail (not shown) for guiding 3 are arranged side by side. When the carriage passes through the rail during this time, the roller 63 pivotally attached to the swing lever 62 abuts and rolls on the open rail or the closed rail, and the swing lever 62 moves to the closed position 62A or the arrow 69 indicated by the solid line in the arrow 68 direction. When the swing operation is performed to the open position 62B indicated by the two-dot chain line in the direction, the remote cable 42 pivotally connected to the swivel lever 62 is driven to open and close the windshield.

[0005]

In the windshield opening / closing device configured as described above, as described above, the carriage with the windshield closed by the swivel lever 62 starts from the stop and moves on the cableway while moving. The vibration of the cable pulling the bearing,
If the windshield, which is in the closed position due to rocking or gusts, opens unexpectedly, the wind receiving area increases, and the transport equipment is more likely to swing, possibly leading to an accident in which the ship may be lost. The present invention has been made for the purpose of preventing the windshield from being opened unexpectedly while such a transport device with a windshield is moving on a cableway line.

[0006]

SUMMARY OF THE INVENTION In response to this object, a ski lift windshield opening / closing operation device according to the present invention provides a ski lift windshield opening / closing mechanism for driving a remote cable to open / close a windshield and a windshield opening / closing mechanism.
