Description

DETAILED DESCRIPTION OF THE INVENTION (a) Purpose of the invention [Industrial field of application] The present invention relates to a chair-type carrier used for a ski lift or the like in the field of cableway, in a chair on which a passenger sits,
The present invention relates to a structure of a lift carrier chair configured for the purpose of keeping the passenger warm and safe.

[Conventional technology]

The cableway has a rope stretched between the pulleys arranged at the terminals at both ends of the cableway (the same applies to the stop).
It is a transport facility for transporting a person or an object by suspending a carrier on a gripping machine fixed to the rope or gripped, and a skier transport request using a chair-type carrier as the carrier mainly in a snowy area. It is well known that equipment that responds to skiing is often used as a ski lift. Recently, ski lifts have been constructed at higher altitudes in the mountains, and the length of the track, which is the transportation section between the terminals at both ends, has become longer,
Therefore, passengers are likely to have longer boarding times and longer exposure to wind and snow.

However, the seat plate of this conventional lift carrier has a soot shape or a plate shape made of a material such as plastic and does not have a heat retaining effect. Further, for example, a cushioning body proposed in Japanese Patent Application No. Sho 57-176958 "Cushioning device for carrier" is fixed to the front surface of the seat plate separately, so that the structure is complicated as a whole and the assembling is complicated. there were.

[Problems to be solved by the invention]

In view of the above-mentioned circumstances, the present invention relates to a lift carrier seat structure, which is a carrier for lifting passengers suspended by a rope,
In winter or in cold regions of mountains, so that passengers transported between the terminals at the foot of the mountain and the summit can ride more comfortably,
A heat insulating seat plate made of foamed resin in the carrier seat, which has a heat insulating effect and an elastic effect and has a curved portion formed in an arc shape in the front,
A notch is opened in the seat plate receiving member, to which the seat plate is to be attached and supported, in which a curved part conforming to the seat plate is formed, and a notch is opened near the curved part of the seat plate, and the notch is fitted and locked. The passenger rides on the carrier by fixing the locking member and the locking member that locks the side portion of the seat plate, and integrally forming an arc-shaped curved portion in front of the seat plate. It is an object of the present invention to provide a chair structure of a lift carrier which has a safety, cushions a shock when it collides with a passenger's foot when the vehicle is moving, has a simple structure, and is easy to assemble.

(B) Configuration of the device [Means for solving the problem] To this end, the chair structure of the lift carrier of the present invention is a lift for transporting passengers by providing a seat on a carrier frame suspended from a rope. In the transporter of the above, the seat is formed by forming a curved portion curved downward in an arc shape in the front and opening a notch in the vicinity of the curved portion, and from a heat insulating material made of a soft elastic body to be seated by a passenger. And a seat plate receiving member on which a curved portion matching the seat plate is formed to support the seat plate, and the seat plate is fitted into a notch portion of the seat plate to mount the seat plate on the seat plate receiving member. And a locking member that locks a side portion of the seat plate to the seat plate receiving member, and the seat plate receiving member is rotatably attached to the carrier frame.

The pin portion of the pin bracket 16 is inserted into 2b and 22b, and is pivotally attached to the carrier frame 8 so as to be rotatable. Further, the pin brackets 16 and 16 have pin portions 16a and 16a penetrated by sleeves 8c and 8c fixed to the lower end of the carrier frame 8,
The bolts 16b, 16b penetrate through the holes 8b, 8b formed in the carrier frame 8 and are fixed to the carrier frame 8 by nuts 16c, 16c.

[Action]

In the lift carrying chair constructed as described above,
The chair 13 is mainly composed of a heat insulating seat plate 20 made of a heat insulating material in its seating portion so that passengers can comfortably get on the carrier in a cold region. However, since the heat insulating material of the heat insulating seat plate 20 is a fragile elastic body, it cannot be fixed to the heat insulating seat plate 20 with a straight line, a bolt, or the like, and does not have rigidity enough to support the weight of the passenger. Therefore,
The heat insulating seat plate 20 is installed in a seat plate receiving member 23 formed of a material such as a steel plate so that its shape is defined and rigidity is obtained. The heat insulating seat plate 20 is integrally formed with an arcuate curved portion 20b at the front end on the traveling direction of the carrying device to cushion the impact when the passenger collides with the foot of the passenger when getting on the carrying device. Further, the heat insulating seat plate 20 having the arcuate curved portion 20b.
Is a locking member 21 having a substantially rectangular curved notch 20a in the center and a fitting portion 21a having the same shape as the notch 20a.
The bolts 21d and 21d and the nuts 21e and 21e
Thus, it is fixed to the chair frame 22 to prevent the central curved portion 20b of the heat insulating seat plate 20 from rising. Further, both side ends of the heat insulating seat plate 20 are embedded with the embedded bolts 31, 31, 31 and the nuts 31a, 31a, 31a and the curved portion by the locking members 30, 30 having substantially the same shape as the heat insulating seat plate 20 in a side view. The bolt 32 is passed through the hole 30c and is similarly fixed to the chair frame 22 with the nut 32a.

Further, the embedded bolts 31, 31, 31 are configured to be embedded inside the locking members 30, 30 in order to complete the seated passenger. Further, the pins of the pin brackets 16 and 16 fixed to the carrier frame 8 in the holes 22b and 22b formed at both ends of the horizontal member 22a at the rear of the chair frame 22 to which the heat insulating seat plate 20 and the seat plate receiving member 23 are fixed. The parts 16a, 16a are inserted and pivotally attached to the carrier frame 8 so as to be rotatable.
Although the chairs 13 and 13 are rotated in the direction of the arrow 40 to have a structure for preventing snow accumulation on the seat, as in the conventional case,
The heat insulating seat plate 20, the seat plate receiving member 23 and the locking member 21, the locking members 30, 30 by forming a semi-circular curved portion,
It has a structure that is less likely to be damaged by the impact during the rotation.

(C) Effect of the Invention As is clear from the above description, the present invention has a structure in which a heat insulating sheet made of a heat insulating material is incorporated into a chair of a chair-type transporter for transporting passengers. By integrally forming the arc-shaped curved part at the tip of the, the function of the shock absorber that was separately fixed to the front of the chair in the past can be used, and it is less likely to be damaged by the impact during rotation. It has a structure. Further, the heat insulating seat plate is firmly fixed to the engaging member having the same shape fitting portion in the notch formed in the central portion and the engaging member seat plates at both ends,
A lift carrier chair for transporting passengers that is more economical and can improve workability during assembly and maintenance can be provided.

(D) Other Embodiments The present invention can have the following embodiments.

(1) A practical use in which a cushion is formed integrally with the seat plate to cushion the impact when the passenger collides with the foot of the passenger when the passenger gets in the seat by forming an arcuate curved portion in the front. Chair structure of lift carrier according to claim 1
