Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an emergency escape mechanism for a lift device provided in a ski resort or the like.

[0002]

[Prior Art]

 For example, lifts are installed at ski resorts, amusement parks, and recreation areas on high ground so that people can be transported to high places with their seats on the seats. In this lift device, generally, a seat is fixed to a lower end of a hanger that is suspended by being pin-connected to a traveling carriage that is moved by a wire rope.

When the lift device stops due to a power outage, a strong wind, or some other cause, the person remains sitting on the seat. And the seats of lifts are often located much higher than the ground, which can make it difficult for personnel to jump to the ground. Especially, it is easy to hurt your ankle if you jump to the ground from a high place while wearing a ski. In such cases, the lifting device was often nailed to the seat for a considerable length of time before it could move again.

[0004]

[Problems to be solved by the device]

 As mentioned above, when the lift device stops and people are stuck on the seat for a long time, while fighting fatigue and fear in high places exposed to the wind, such as ski areas, in extremely low temperatures. I had to stay.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an emergency escape mechanism capable of easily descending from a seat of a lift device that has stopped to the ground.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a lattice-like ladder made of metal pipe that is folded and stored in the lower surface of a seat of a lift device in a state of being folded in one or more, and a storage means for maintaining the ladder in a stored state. In an emergency, you can release the storage while sitting on the seat and deploy the ladder by dropping it by its own weight; and the front end of the seat and one end of the ladder to suspend the deployed ladder on the front of the seat. And a hinge connecting the two.

[0007]

[Action]

 In an emergency when the lift device stops, a person trying to get out of the seat and escape from the seat, while sitting on the seat, activates the release means to drop the ladder by its own weight and deploy it downward. At this time, one end of the ladder is connected by a hinge, and the ladder is suspended on the front surface of the seat. Then, the person turns backwards toward the seat, extends one foot downwards, and descends to the ground while traveling down the ladder.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is an overall perspective view showing a state in which a ladder is deployed by the emergency escape mechanism of this embodiment. FIG. 2 shows a side view of the main part of FIG. Figure 3 shows the ladder folded.

In this lift device, a traveling carriage 3 is moved by being pulled by a wire rope 5 along a rail 1 having an I-shaped cross section. A hanger 7 is connected to a pin 9 at the lower end of the traveling carriage 3. At the lower end of the hanger 7, a seat 11 on which several persons can sit is fixed in a horizontal state.

A ladder 13 is provided on the lower surface of the seat 11. The ladder 13 is made of metal pipe and is formed in a lattice shape by a step 15 or horizontal pipes and a plurality of joint members 17 or vertical pipes. In this embodiment, the ladder 13 has two members 13A and 13B connected by a hinge 19 so that it can be folded in two. It is preferable that this hinge 19 does not spread over 180 ° when the ladder 13 is expanded, that is, the lower ladder 13B is stabilized when a person descends along the ladder 13. One end (upper end in FIG. 1) of the ladder 13 is connected to the front end of the seat 11 by another hinge 21, that is, the front end of a frame 23 provided on the lower surface of the seat 11.

A lock arm 24 is provided between the rudder 13 and the frame 23 so that the ladder 13 is stable when it is hung and deployed. That is, in this lock arm 24, one end of the first arm 24A is pin-connected to the intermediate step 15 of the upper ladder 13A of the two provided ladders 13A and 13B, and the other end of the first arm 24A is the second Is pin-coupled to one end of the arm 24B. The other end of the second arm 24B is pin-connected to the frame 23 on the lower surface of the seat 11. The entire length of the lock arm 24 is dimensioned to be fully extended when the ladder 13 is expanded and suspended substantially vertically, or when the lower end is slanted toward the front of the seat. After being fully extended in this way, the lock arm 24 is less likely to be folded down, so that the ladder 13 can be locked in the above state. Guides 26 (see FIG. 1) for guiding the ladder 13 to the stored state are provided on both sides of the lower portion of the frame 23.

The accommodating means 25 for maintaining the ladder 13 in the accommodated state includes a pair of Hanging lock claws 27 (see FIG. 4). That is, hanging lock claws 27 are provided on the lower surface of the center of the frame 23 in the left-right direction (see FIG. 1) with respect to the main plate 29 at the front and rear ends of the sheet 11. The hanging lock claw 27 is substantially L-shaped as a whole, the lower end of the L-shape supports the lower side of the pipe of the folded ladder 13, and the center of the hanging lock claw 27 is fixed to the claw frame 33 by a pin 31. The claw frame 33 is rotatably assembled to the main plate 29 by a mounting plate 35 provided integrally therewith. The upper end of the hanging lock claw 27 is fitted to the hanging lock catcher 37. That is, the hanging lock claw catcher 37 is provided by a support 39 so as to be movable in the horizontal direction with respect to the main plate 29, and has a rectangular hole 41 at one end to have a rectangular cross section. The upper end of is inserted and fitted. The other end of the hanging lock catcher 37 is pin-connected to one end of the link member 43, and the other end of the link member 43 is pin-connected to one end of the rotary arm 45. The center of the rotating arm 45 is connected to the above-described main plate 29 by a rotary frame 47, and is rotatable in a plane parallel to the main plate 29.

The above-mentioned set of the hanging lock claw 27, the claw frame 33, the hanging lock catcher 37, and the link member 43 are provided at the front and rear ends of the seat 11, respectively.

A wire arm 49 is fixed to the rotating arm 45, and is forcibly rotated by a wire 51 fixed to the tip. The wire 51 can move back and forth relatively inside the wire jacket 53. The wire jacket 53 is fixed to the base plate 29 by a wire mounting plate 55. The wire jacket 53 and the wire 51 are connected to a handle 59 of a releasing means 57 described later.

A release means 57 for unlocking the storage of the ladder 13 by the storage means 25 is provided on a side portion of the seat 11 as shown in FIGS. 2 and 3, and as shown in FIGS. 6 and 7. The wire 59 is pulled by the handle 59. That is, the bearing plate 63 is fixed substantially parallel to the main plate 61, and the handle 59 is rotatably provided by the snap rotation shaft core 65 penetrating between the two plates 61, 63. The wire 51 is fixed to the base of the handle 59. The wire jacket 53 is fixed to the main plate 61 by a wire mounting plate 67. A lock pin 69 is provided so that the releasing means 57 does not unnecessarily perform the releasing operation, that is, the handle 59 does not unnecessarily rotate counterclockwise in the drawing. That is, the two plates 61 and 63 have the lock pin penetration holes 71 formed at the corresponding positions so that the lock pins 69 can be inserted. In the inserted state, the lock pin 69 contacts the handle 59, and the handle 59 cannot rotate counterclockwise in the figure.

Next, the operation of this embodiment will be described. When the lift device stops due to strong wind, power failure, malfunction, or any other reason, and the person sitting on the seat 11 attempts to get out on the ground and escape, the handle of the release means 57 should be kept on the seat. 59 is rotated counterclockwise (see FIG. 2 or FIG. 6). This rotation pulls the wire 51, and this wire 51 rotates the rotating arm 45 of the housing means 25 (see FIG. 5) in the counterclockwise direction in the figure. As a result, the rotary arm 45 pulls the link member 43 and the hanging lock catcher 37 retracts in the horizontal direction. Therefore, the hanging lock claw 27 rotates around the pin 31 and the lower end retracts from the ladder 13 (see FIG. 5 or FIG. 2). This retreat causes the rudder 13 to drop under its own weight without losing its support. One end of the rudder 13 is suspended by a hinge 21, and the two ladders 13A and 13B are deployed in a substantially vertical state with a hinge 19 connecting them in between. At this time, the rock arm 24 is pulled by the force of the rudder 13 dropping, and is in a fully expanded state. Therefore, the upper ladder 13A of the two ladders 13A and 13B is locked to the seat 11. Also, since the hinge 19 that connects the two ladders 13A and 13B cannot be opened more than 180 °, the lower ladder 13B can be tilted or swayed backwards relative to the upper ladder 13A. There is no. Therefore, the two ladders 13A and 13B are locked to the seat 11.

In this state, the person sitting on the seat 11 turns rearward with respect to the seat 11 and extends one leg downward while being held by the seat 11. Then, after one foot is placed on the first step 15 of the ladder 13, the other foot is extended further downward. During this time, the metal pipe rudder 13 can be kept in a locked state with respect to the seat 11, that is, a stable state, and a person can easily and safely escape to the ground along the rudder 13. . Even if the distance from the lower end of the deployed ladder 13 to the ground is long, the impact of jumping down can be alleviated by the deployment of the ladder 13.

In the above embodiments, the lock arm 24 is a simple one composed of two arms 24A and 24B, but in other embodiments, three or more arms are used to make it more secure. It may be for locking. The lock arm 24 may be provided with a link mechanism capable of locking not only the upper ladder 13A but also the lower ladder 13B.

Further, in another embodiment, a bumper for gently dropping the ladder 13 may be provided. This bumper can prevent the seat from shaking and becoming unstable due to the fall of the rudder 13, and at the same time, the lock arm 24 is sufficiently extended without damaging the falling force of the rudder 13 too much. Be able to work.

Further, in the above embodiments, the ladder 13 was described as being suspended substantially vertically (FIGS. 2 and 1), but in other embodiments, the lower end of the ladder 13 is moved forward and the entire ladder 13 is moved. The lock arm 24 may be configured so that the person can incline so that the person can escape more easily. Further, a mechanism other than the lock arm 24 may be additionally provided, which is capable of locking the state in which the rudder drops due to its own weight and moves further toward the front of the seat 11 than in the vertical state. Furthermore, the ladder 13 may be folded in two or more folds.
