Description

[Detailed Description of the Invention] The present invention relates to an escape device installed at the second floor emergency exit of a second floor bus.

In recent years, buses on the second floor have been used for reasons such as good views, but the emergency exit on the second floor is accessible from the ground.
Since it is located at a height of more than 2 meters, it is necessary to provide some means of escape. For this reason, in the past, escape ropes, folding ladders, etc. were removably attached to the interior wall of the car near the second-floor emergency exit, and in the event of an emergency, they could be removed and attached to the emergency exit. Also, ensuring safe escape is something that should always be considered.

The present invention was proposed in order to improve the conventional escape device, and the object is to provide an escape device that allows escape quickly and safely by simply opening the second floor emergency door. The gist of the present invention constructed to achieve this purpose is to have an emergency door that is attached to the side edge of the second floor emergency exit via a hinge so that it can be opened and closed freely, and a lower surface of the emergency door that is formed on the inside side of the car. A folding box that is stored in the box that is open and has a lid hinged to the front, and one end of each of a pair of support cables is attached to positions near both ends of the lower edge of the second floor emergency exit. There is an escape device on the second floor of the bus, which consists of a ladder.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a rear perspective view of a second-floor bus showing the state in which the escape device according to this embodiment is used, and an emergency exit 3 is formed in the second-floor rear surface 2 of the second-floor bus 1. The emergency exit 3
An emergency door 5 is attached to the side edge 3a via a hinge so that it can be opened and closed laterally outward. As shown in FIGS. 2, 3, and 4, a window 6 is provided at the top of the emergency door 5, and a box 8 whose bottom surface is open is formed at the bottom of the window 6. The box 8 has both side plates 9a, 9
b, is composed of an outer plate 10 and a lid body 11,
The lid body 11 is attached to the side plate 9b via a hinge 12 riveted to the side plate 9b so as to be openable and closable laterally inside the vehicle.

A stepped portion 4 is formed at the lower edge 3b of the emergency exit 3, and a stepped portion 4 is formed with the outer side of the vehicle lowered, and a pair of support pieces 15 are rotatably pivoted at positions near both ends of the upper surface of the stepped portion 4. There is. As shown in FIG. 4, the support piece 15
has such a length that its tip 15a protrudes outward in an overturned state, and one end of each of a pair of support cables 18 constituting the folding ladder 16 is attached to the tip 15a, respectively. The support cables 18 have a length that almost reaches the ground, and are inserted into holes provided near both ends of the footboards 19a, 19b, and fixed horizontally at a constant interval.

Next, how to use the escape device will be explained. Normally, the folding ladder 16 is placed with its free end up and the tread 1 as shown in FIGS. 2 and 3.
9a, 19b, . . . are stored in the box 8 in a stacked state from the bottom. To explain this storage procedure, the folding ladder 16 is pulled up to the second floor inside the car, the emergency door 5 is closed, the lid body 11 hinged to the emergency door 5 is opened, and the tread plate 19 is opened as described above.
After stacking the items a, 19b, . . . , the lid body 11 is closed.
When in use, when the emergency door 5 is completely pushed open, the support piece 15 is pulled by the support cable 18 stored in the case 8 and rotates outward, and then the bottom opening of the case 8 is opened. The treads 19a, 19b, . . . fall one after another, and an escape ladder 16 is vertically installed from the lower edge 3b of the emergency exit 3 near the ground.

As detailed above, according to the present invention, a folding ladder is stored in a box formed in the emergency door of the second floor emergency exit, and the folding ladder is automatically moved from the emergency exit just by opening the emergency door. Since the escape device is vertically installed, it can be operated extremely easily and quickly.
In addition, since the folding ladder is attached to the lower edge of the emergency exit via a support piece, it does not fall off during use and is highly safe.
