Abstract

PURPOSE:To improve pivot-turning operability of a windshield by permitting torsional reaction of a torsion bar to assist pivot-turn operating physical force in turning the windshield to positions of 'opening' and 'closing' when the windshield pivot turns to the positions 'opening' and 'closing'. CONSTITUTION:With the carrier 1 with a windshield, a suspension frame 9 is hanged on a cable gripper 2 through a pin 4, and a torsion bar 31 whose one end is restricted on a carrier frame 10 side and other end is restricted on a torsion frame 30 pivot turning together with the pivot turning action of the windshield 11, is loaded on a pivot-turning shaft of the windshield 11. Thus, the torsion bar assists the operating physical force in opening and closing the windshield and facilitates the opening and closing operations of the windshield by passengers or a windshield opening device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a windshield opening/closing mechanism for a ski lift for facilitating pivoting operation of the windshield when the windshield is attached to a cableway ski lift.

[Prior Art] In a circulating cableway, cables are stretched and circulated around pulleys installed at both terminals, and a rope gripping machine with a carrier suspended thereon is gripped by the cables to transport large objects or objects. However, in recent years, automatic circulation cableways have been developed in which cable gripping machines for the carriers roam the cables at both terminals and are transported at low speeds. They tend to be built at higher elevations in the zone. Therefore, the passengers in the carrier were exposed to the wind and snow during transportation, causing discomfort. As a countermeasure against wind and snow, ski lift carriers are equipped with windshields made of transparent synthetic resin molded into a capsule shape or a shell shape with a semi-elliptical curved surface to cover the front and both sides of passengers riding on the carrier. It has recently started to be used. However, when a passenger gets on or off the windshield carrier, the passenger must pivot the windshield to open and close it, and a pivoting force is required to operate the windshield. In some cases, the pivoting force was a problem.

[Problems to be Solved by the Invention] This invention was proposed in response to the above-mentioned circumstances, and its purpose is to provide a windshield opening/closing mechanism for a ski lift that improves the pivoting operability of the windshield of a windshield-equipped carrier. There is.

[Means for solving the problem Fa] Corresponding to this object, the windshield opening/closing mechanism of the ski lift of the present invention pivots the windshield that is pivotally connected to the carrier frame.
A windshield opening/closing mechanism for a ski lift carrier that assumes an "open" or "closed" position, the windshield being supported by bearings on both sides of the carrier frame for pivotal displacement, and the other end being restrained to the carrier frame side. The end consists of a torsion bar penetrating and restrained within a torsion frame that is on the pivot axis of the windshield and pivots with the windshield, so that when the windshield pivots to the "open" and "close" positions, The invention is characterized in that the torsional reaction force of the torsion bar assists the pivoting force of the windshield to the "open" and "close" positions.

[Function] In the ski lift windshield opening/closing mechanism configured as described above, when opening the windshield pivotally connected to the carrier frame, the torsion bar is twisted due to the relative displacement between the carrier frame and the windshield, and the elastic reaction force is assists the operating force to close the windshield.

[Example] Hereinafter, details of the present invention will be explained with reference to drawings showing an example.

On the other hand, when the windshield 11 is rotated in the direction of the arrow 16 mentioned above and reaches the "open" position indicated by the chain line in FIG. 2, the windshield frames 11a on both sides of the windshield 11.

The torsion frame 30 fixed between the parts 118 also rotates in the same manner.

In the above-described state, the torsion block 31a fixed to one end of the torsion bar 31 also rotates because it is fitted inside the torsion bar 31, but the other end of the torsion bar 31 is rotated as shown in FIGS. As shown in the figure, it is fixed to the carrier frame 10, similarly fixed to the bearing frame 38, fitted into the square hole 40a of the fixing ring 40, and fixed with the set bolt 42, so that it does not rotate.

Therefore, when the windshield 11 is in the "open" state, the torsion bar 31 in the torsion frame 30 is in a twisted state, generating torsional stress. That is, the first

Similarly, a restoring force in the direction of the arrow 16 also acts in the "closed" state of the windshield 11, which is indicated by a solid line. Therefore, it is easier for passengers to open and close the windshield 11, or to open and close the windshield 11 via the remote cable 8 of the swinging motion of the lever 6, for example, by the windshield opening/closing device (not shown). It is possible.

On the other hand, the seat plate 60 has a structure that rotates in the directions of arrows 72 and 73 around a seat plate bin 61 installed between both sides of the carrier frame 10 near the lower center of the seat plate 60. It has become. In addition, seat plate frames 64, 64 are arranged parallel to the seat plate bin 61 in the front and rear directions near the front side, which is the side in the traveling direction of the carrier 1, and the rear side, which is the opposite side, of the lower flat part of the seat plate 60. Made of elastic material such as rubber! l
The iI body 63.63 is attached to the seat plate 60 so as to absorb the impact when the seat plate 60 rotates in the directions of the arrow 74° and the direction of the arrow 75.

rotates in the direction of arrow 72 around the hinge pin 61 of the seat plate 60, and therefore the seat plate 60 also rotates around the hinge pin 61.
The seat plate 6 swings in the direction of arrow 75 with reference to 1 as the center and is indicated by a chain line.
Tilt to 0 position. That is, the seat plate 60 of the carrier 1 swings in synchronization with the opening/closing operation of the windshield 11.

FIG. 10 shows that when the windshield 11 of the carrier 2 is rotated in the direction of the arrow 16 to the "open" position shown by the chain line, the suspended rope is suspended via the bin 4 inserted into the rope gripper 2 of the carrier 1. The suspension frame 9 is suspended as shown by the chain line by moving in the rear direction of the carrier 1, where the center of gravity of the entire frame 9 and below is on the right side in the figure.
At this time, the windshield 11 tilts forward by θ with respect to the "closed" state shown by the solid line.At this time, due to the above-described structure, the seat plate 60 is similarly moved in synchronization with the "open" operation of the windshield 11, shown by the chain line. It is tilted by θ to the same position.

[Effects of the Invention] The windshield carrier of the present invention is equipped with a torsion bar on the pivot axis of the windshield, one end of which is restrained to the carrier frame and the other end of which is restrained to a torsion frame that pivots along with the pivoting movement of the windshield. By doing so, the operating force for opening and closing the windshield is assisted, thereby facilitating the opening and closing operation of the windshield by the passenger or the opening and closing operation by the windshield opening and closing device. Furthermore, even if the capacity of the carrier increases, the windshield becomes larger, and the moment for opening and closing the windshield increases, this can be easily handled by changing the torsion characteristics of the torsion bar.

In addition, by linking the opening/closing operation of the windshield with the pivoting movement of the seat plate in the direction in which the carrier advances, the inclination of the seat plate in the direction of movement of the carrier due to the movement of the center of gravity when the windshield is opened is corrected. By equipping the vehicle with a seat plate correction mechanism, passengers can more easily and safely get on and off the windshield carrier.

A windshield opening/closing mechanism for a ski lift as set forth in the claims, comprising a seat plate correction mechanism that pivots a seat plate of the carrier in the traveling direction of the carrier in conjunction with the opening/closing operation of the windshield. .
