Description

[Detailed Description of the Invention] The present invention relates to a carrier release mechanism used in a climbing device of a rope lift for transporting skiers, small sleds, etc. at a ski resort or the like.

In recent years, rope lifts have often used carriers with fishing equipment, but in the case of conventional fishing equipment with light handles such as strings, a cylindrical tip end is used in the middle of the rope. Was it possible to easily remove the carrier by hand by placing a stopper member with an appropriate end?
Removing relatively light carriers such as straddle-type carriers by hand each time requires excessive labor due to their weight, and the weight acts in the direction of maintaining the engagement between the hooking device and the rope. It becomes increasingly difficult to remove.

The present invention is a mechanism that can automatically remove a relatively heavy carrier from its original state.

The present invention will be explained below according to the drawings.

FIG. 1 is a schematic diagram of a preferred overall climbing device in which the carrier separating mechanism according to the present invention is used. A motor and a drive pulley driven by the motor are placed on M, and this drive pulley allows an endless rope to be mounted. moves in the direction of the arrow.

This endless rope is extended by end boos IJ-P installed at low and high locations, and skier 8 hooks the hooking device of the carrier E onto the extended ascending rope and secures the main body of the carrier. You can climb the slopes by holding the bar between your thighs and the seat of the carrier body against your buttocks.

Such carriers are, for example, relatively heavy hoof-shaped as shown in FIG.

That is, this is a hooking device 29 for engaging with the rope.
The hooking device 29 has groove plates 17 and 18 arranged side by side at an interval on the upper part of the base 15, and the lower part is a rod for connecting the carrier body 30.

Further, the carrier main body 30 has a structure in which the front end is a connecting portion and the rear end of a rod-shaped body 31 is circularly bulged to form a seat portion 32.

Carriage E shown on the descending rope is collected for reuse at a low point.

The lower end boo IJ-P is connected to a support device G1 on which the tensioning means is arranged, and the higher end boo IJ-P is connected to a support device G2.

Further, the ascending cable is supported by support pulleys 1 and 2 at both ends thereof, and the support pulley at the high end has the carrier detachment mechanism of the present invention attached to its column.

The cable support devices 3 and 4 used for the descending cable are used to properly tension and support the cable, change the direction of the cable, and determine the passage course.Finally, the support device 5 has a hooking device. 2
A carrier recovery mechanism is provided which cooperates with 9.

Incidentally, since the support boos IJ-1 and IJ-2 on the upstream cable side and the end boob IJ-P are generally installed in a place where people can approach them, a protective cover is provided as shown in the figure for safety measures.

FIG. 2 shows a forwarding mechanism in which the skier leaves the carrier and the carrier 10 hanging from the rope is released by the hooking device 29, and the mechanism of the present invention is attached to the support pulley 2 shown in FIG. 1. .

In the drawing, the conical base 21 is the spring 2.
2, and the cylindrical base of the cap 21 is preferably grooved to allow the spring receiver to connect and secure the cap and spring in any suitable manner.

The structure of this part is more clearly shown in the sectional view of FIG.

Due to the flexibility of the spring 22, the cap 21 adapts to swinging or bending of the cable, so that friction generated when the cable passes inside the cap does not become a problem.

The spring 22 is held by a substantially cylindrical spring retainer 23, which is fixed to the upper part of the column of the support pulley 2 in accordance with the slope of the ascending cable.

In this embodiment, the spring retainer 23 has two integrally manufactured legs 24, each of which is threaded at its tip.

These two legs are inserted into the holes 27 of the mounting plate 26 from both sides with nuts 25 and fixed so as to be adjustable in position.

The nuts shown on the front side may be fixed in advance by welding or the like.

The mounting plate 26 is attached to a bent arm 28 that is attached to a post of the support pulley 2.

Furthermore, the hole 2T in the mounting plate is a long, crescent-shaped hole that is convex in the direction away from the support pulley 2, so as to correspond to the slope of each slope on which the present pitching device is used.

FIG. 4 is an explanatory drawing showing the manner in which the hooking device 29 is removed from the cable by the mechanism of the present invention, and is shown in FIG.

B and C indicate the position of the hooking device in FIG. 2.

It shows the relative relationship between the cable and the hook part as seen from the direction of the arrow at the position C, and shows that if the condition shown in Figure 4 C is reached, the hook part will come off from the advance mechanism and the carrier will fall. be understood.

That is, at part A, the cable is fitted into the groove between the base 15 of the hooking device 29 and the groove plate 17, but when the hooking part starts to climb up the conical part 21 at position B, the cable is removed from the groove into a conical shape. When the part protrudes and reaches the bottom of the conical part shown at position C, the hooking function of the groove disappears due to its thickness, and the carrier falls under its own weight.

Therefore, the thickness of the conical base may be at least an appropriate thickness corresponding to the size of the groove of the hooking portion.

Therefore, according to the present invention, the carrier abandoned by the skier is automatically taken off the line by the advance mechanism and dropped, so the relatively heavy carrier such as a straddle type has to be manually lifted and taken off the line each time. This saves you the trouble and overwork of having to do this.

The mechanism of the present invention can also be used by being attached to the cable support device 3 at the lower end.
