Description

[Detailed description of the invention] This invention relates to a device for lowering users one by one from lifts installed at ski resorts, recreational areas, etc. in the event of an emergency.

Lifts that transport people must be equipped with a device that safely lowers users to the ground in the event of an emergency where the lift stops for some reason.

However, the one actually used is a simple one with a hook attached to the end of a bamboo pole, and the hook is hooked onto a cableway and the bamboo pole is suspended and then slid down to the ground.

In the case of this bamboo pole, since the hook was simply hooked onto the cableway, the hook could come off due to the reaction when the user moved onto the bamboo pole or descended to the ground.

Furthermore, even in strong winds, staff had to hold the bamboo poles, making it difficult to say that it was necessarily safe.

This idea was developed based on the above considerations; once the hook is hooked to the cableway, it will not come off unless it is removed manually, and for descent to the ground, a rope that is completely different from the bamboo pole is used. An arbitrary sliding device is attached to the rope to allow the user to descend safely, and the device consists of a pulley and a hook.

This invention will be explained in detail below using illustrated examples.

1.1 is a pair of frame plates having an upper end plate 2.

A pulley 4 of a descending rope 3 is installed with a shaft between the lower ends of the frame plates 1, 1.

Further, above the pulley 4, a braking cam 5 is provided with a shaft 5a shifted to one side of the frame plate, and the braking cam 5 always engages the rope 3 with the pulley 4, so that the movement of the rope 3 is limited to one direction only. A spring 6 is provided between the brake cam 5 and the frame plate 1 to regulate the movement.

Reference numeral 7 denotes a cableway hook connected to the upper end plate 2, and is attached with the hook tip 7a located on the opposite side of the brake cam 5, and the hook 7 has an upper end located inside the hook tip 7a at the base. The opening/closing member 8 is attached with a spring 9 always acting in the closing direction.

Opening members 10 and 11 are provided at the upper end of the hook opening/closing member 8 and the free end of the brake cam 5, respectively, and a member 1 connected to the opening members 10 and 11 by a frame is provided.
2, the braking cam 5 and the hook opening/closing member 8 are integrally linked on the back side of the hook, so that the braking cam 5 and the hook opening/closing member 8 open simultaneously when the hanging ring 13 provided on the member 12 is held. It has become.

The illustrated opening members 10 and 11 are annular, and the opening member 10 is fitted from the tip of the hook opening/closing member 8 to the back side of the hook and connected to the member 12, but the shape and mounting structure of the opening member can be arbitrarily changed depending on the design, so it is not limited to the example.

To hang the above device on the cableway 14, as shown in FIG.

By this lifting, the device sinks directly below due to its own weight, and conversely, the member 12 moves upward, pulling the opening/closing members 10.11 connected to both ends of the member.

Furthermore, since the support point of the device is the shaft 5a of the control cam 5, the device tilts toward the tip of the hook, and as a result, the hook opening/closing member 8 opens and the braking cam 5 also opens, making the rope 3 free. Become.

Next, when the arm 16 is removed and the device is released from the hook rod 15, the braking cam 5 and the hook opening/closing member 10 return to their original positions as shown in FIG. bites and holds the rope 3, and the hook opening/closing member 10
closes the hook 7 and prevents the cableway 1 from closing under any conditions.
4 to prevent it from coming off.

In such a situation, the rope on the side receiving the brake (
Users can descend via the bridge (left side in the drawing).

In addition, if the user wants to descend smoothly, the braking rope should be attached to a descending device (for example, Utility Model 111800
It is only necessary to attach a grip (as described in the above publication), and since the braking of the rope 3 is to the left, the device that has slid down can be easily returned by tracing the rope 3 to the right.

Further, although both ends of the rope 3 may be cut off, it is preferable that the rope 3 be spliced into an endless shape.

This device, which can be hooked onto the cableway 14 as described above, can be used for lifts at ski resorts as shown in Figure 3, and not only can it safely lower skiers in an emergency, but it can also be used as a tourist attraction, although the diagram is omitted. It can also be used for ground lifts.

As mentioned above, this invention consists of the braking cam 5 of the pulley 4 of the descending rope 3 that is installed between the lower ends of the frame plates 1 and 1, and the hook opening/closing member of the cableway hook 7 that is connected to the upper end of the frame plates. The opening members 10 and 11 each provided with 8 and 8 are integrally connected by the member 12 provided with the hanging ring 13 on the back side of the hook. Since both the hook opening/closing member and the braking cam are opened by ', the rope 3 is also in a free state, and even if there is a sliding device in the middle of the rope 3 and the load is heavy, the load will cause the rope 3 to move downward. Since the load is removed, it is easy to lock onto and remove from the cableway.

Furthermore, since the hook is closed by the hook opening/closing member after being hooked onto the cableway, the hook will not come off even if it receives reaction or vibration.

Furthermore, since the rope is clamped between the pulley and the braking cam at the same time as the hook is closed, it is possible to descend by holding the rope on the fixed side or both ropes, and in some cases it is possible to descend using a descending device. It has advantages such as being able to

Moreover, unlike bamboo poles, ropes can be tied up and placed, making them easy to store and extremely easy to transport to the site.
