2. Description of the Related Art Ski lifts at ski resorts are necessary for efficiently transporting a large number of ski passengers to high places such as mountain peaks, and are currently operated at ski resorts everywhere. . Various types are known, including those for one passenger and those for multiple passengers. In such ski lifts, those with a hood have been used for the purpose of ensuring the safety of passengers and protecting the passengers from wind and snow. Such a type of ski lift is provided with a ski lift carrier that is suspended from a rope and transported, and a hood that is provided to be pivotally supported on the ski lift carrier to protect passengers during transportation, and the hood is By providing the ski lift carrier so that it can be rotated, it can be opened and closed between the protective position and the jumping position, protecting passengers from falling etc. during transportation, while being able to easily get on and off when getting on and off. There is.

By the way, in the above-described ski lift with a hood, the hood opening / closing mechanism holds the hood in a protective position covering the ski lift carrier, while allowing the hood to be easily jumped up and down when getting on and off. Is desired. Then, normally, a torsion bar is provided on the shaft support portion of the hood for the ski lift carrier, and the spring force due to the twist amount is set to zero at a position half of the hood opening / closing angle (for example, 80 degrees), For example, in the hood protection position, the hood can be turned in the direction of hoisting with a predetermined spring force, and its closed state can be maintained by a simple lock. It was generally done to be operable. On the other hand, when the hood is in the flipped-up state, a spring force acts in the closing direction, so that the hood can be closed with a light force.

[0004]

However, in the hood opening / closing mechanism of the conventional ski lift with a hood described above, the adjustment work of the adjusting mechanism portion for adjusting the spring force of the torsion bar is extremely troublesome and complicated, and labor is required. In addition to the above, there is a problem in that durability is also a problem.

That is, in the past, as a spring force adjusting mechanism of this type, generally, one end of the shaft supporting portion of the bracket on the ski lift carrier side and the bracket on the hood side is penetrated while being fixed to the hood side. The other end of the torsion bar is fixed to the adjustment plate, and the adjustment plate is attached to the bolt / nut while positioning the rotation position by the insertion position with respect to the long groove formed in the bracket on the carrier side. A structure was adopted in which they were fastened and fixed.

In such a conventional structure, in order to adjust the spring force, the adjusting plate is attached to the torsion plate and the opening / closing angle of the hood with the cover or the like protecting the shaft support removed. It is necessary to perform the troublesome work of positioning the insertion position with respect to the long groove of the carrier side bracket and fastening and fixing with bolts and nuts while positioning and, so that it can be finally adjusted by three people. It was a structure. In addition, since the bolt is inserted into the long groove, if it is used for a long period of time, the nut or the like may be loosened, which may cause a deviation, which requires frequent readjustment work. In particular, such a ski lift is used in a severe use condition, and it is necessary to adopt a configuration that can easily and reliably perform the above-mentioned adjustment work. In consideration of such a point, it is desired to take some measures capable of eliminating the above-mentioned problems.

In order to meet such a demand, the hood opening / closing mechanism of a ski lift according to the present invention is
A carrier-side bracket and a hood-side bracket that form a shaft supporting portion between the ski lift carrier and the hood, and one end fixed to the hood side, which is arranged so as to penetrate the shaft supporting portion formed by these both brackets, and around the shaft supporting portion due to a twist amount. Of the torsion bar, the other end of the torsion bar is fixed, and the adjustment bracket is rotatably provided on the pivotal support portions of both brackets, and is fixed to a part of the adjustment bracket and the carrier side bracket. The adjustment screw to be screwed between the screwing bracket piece provided on the member to be mounted and the adjustment piece for adjusting the gap between the bracket pieces depending on the screwing position of the adjustment screw is adjusted to the bracket on the carrier side. It is configured to change the angular position of the bracket for adjusting the spring force of the torsion bar. That.

[0008]

According to the present invention, the torsion bar fixed to the adjusting bracket is adjusted by rotating the adjusting screw to arbitrarily adjust the rotating position of the adjusting bracket with respect to the carrier side bracket. The amount of twist can be adjusted arbitrarily, and the spring force can be adjusted to the required state according to the opening / closing angle of the hood.
