FIG. 1 is a front view and a cross-sectional view of the main parts of a conventional suspension wheel vibration isolator shown in the issue of the newsletter; in the figure, (1) is the main rope (2);
The hanging wheel around which (8) is hung is this hanging wheel (1)
The upper beam (4) is attached to the hanging wheel (1) and the upper beam (8).

In the above-described nine-wheel suspension vibration isolator, the suspension wheel (1) is rotated by the main rope (2) while the seat (γ) is raised and lowered. At this time, the vibration isolating rubber (4) prevents the vibration of the main rope (2) from being transmitted from the hanging vehicle (1) to the passenger seat (7) via the upper beam (8).

出が容易となる。Since the conventional suspension vehicle vibration isolator is configured as described above, the suspension vehicle (1) and the ceiling of the passenger seat (7) are close to each other, and as a result, the rescue exit provided in the ceiling of the passenger corner ( This invention was made to solve the above-mentioned problems, and it is difficult to rescue passengers from the ceiling of the car. It is an object of the present invention to obtain a vibration isolating device for a suspended vehicle, which allows rescue to be carried out easily without any hindrance, and which is equipped with vibration isolating means for passengers. The device has an elastic body interposed between the vertical frame of the passenger car and the upper beam to which the suspension wheel is attached. However, the vibrations from the upper beam to the vertical frame of the car can be damped by an elastic body. Moreover, since the space between the hanging car and the car ceiling can be increased, it becomes easier to rescue passengers from the car.

〔Example〕

以下、この発明の一実施例を図について説明する。第１
図において、（８）は上梁を示し、（６）は乗かとの縦
枠を示している。縦枠（６）は上梁（８）の天板（３ａ

防振ゴム（８）が介在され、ボルト（９）で上梁（４）
と縦枠（６）とが締結されている。An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, (8) shows the upper beam, and (6) shows the vertical frame of the seat. The vertical frame (6) is the top plate (3a) of the upper beam (8).
It consists of a key shape that engages along the side plate (3b),
A vibration isolating rubber (8) made of an elastic body is interposed between the joint between the upper beam (4) and the vertical frame (6), and the upper beam (4) is fixed with a bolt (9).
and the vertical frame (6) are fastened.

れる。これにより乗かとへは吊ｐ車からの振動が伝わり
にくく乗かどの最適な乗心地となる。In the vibration isolator configured as described above, vibration is transmitted from the hanging wheel (not shown) to the upper beam (8), but the vibration is absorbed by the vibration isolator (8) in the vertical frame (6) of the riding girder. and attenuated. This makes it difficult for vibrations from the suspended vehicle to be transmitted to the passengers, resulting in optimal riding comfort.

る。In addition, although the anti-vibration rubber (8) was attached to the vertical frame (6) side or simply interposed between the upper beam (8) and the vertical frame (6), an elastic body was also attached to the bolt (9). By wrapping it around, the transmission of vibrations from the upper beam (8) to the vertical frame (6) can be more effectively damped.

〔Effect of the invention〕

の乗客の救出が容易に行なえる等の効果がある。As described above, according to the present invention, by interposing an elastic body in the fastening portion between the vertical frame of the passenger car and the upper beam to which the suspended car is attached, vibrations from the suspended car are prevented from being transmitted to the car. In addition to providing an anti-vibration effect, since there is no vibration isolating device between the suspension car and the upper beam as in the past, there is a large space between the passenger heel and the suspension car, and the ceiling of the car can be reduced. This has the effect of making it easier to rescue passengers from the rescue exit.
