Description

[Detailed Description of the Invention] This invention comprises a movable tread plate consisting of a main tread plate and an auxiliary tread plate, and allows vehicles such as wheelchairs and baby carriages to be carried by being placed on the main and auxiliary tread plates that constitute one set of movable tread plates. This is related to the escalator treads.

Conventionally, escalators equipped with the above-mentioned treads have been known, but in such escalators, the live treads and the auxiliary treads maintain the same horizontal plane on the outbound path of the circulation path, so it is difficult to use wheelchairs, etc. There was a problem in that there was a risk of accidents such as vehicles falling off the moving treads.

This invention attempts to solve the above-mentioned problem, and the present invention aims at at least the inclined part of the outbound path of the circulation path so that the upper surface of the main tread plate is raised at the opposite end from the connection part with the auxiliary tread plate. To provide a highly safe escalator footboard that can prevent vehicles such as wheelchairs from falling from the movable footboard by tilting.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

In the figure, 1 is the circulation path of the escalator, and this circulation path 1
has an inclined outward path 1a, a return path 1b, and a reversing portion 1c which is a connecting portion thereof, and also has a second rule 2 arranged on both sides, and a second rule arranged below the second rule 2 in the outward path 1a. 3. A third rail 4 is provided. Reference numeral 5 designates a main tread plate, and the raw tread plate 5 has a first rolling wheel 6 pivotally attached to one end and supported by the first rule 2, and a first rolling wheel 6 disposed at the other end. The second roller 7 is also provided with a second roller 7 which projects downward, is pivotally mounted, and is supported by the second rail 3. 5a is the upper surface of the main footboard 5, 5b is a sign band provided on three sides of the upper surface 5a, and 5C is a bearing device provided at the side edge of the main footboard 5 on the upper side of the forward path 1a. 8
The main footboard 5 has one end rotatable by a bearing device 5a.
The auxiliary footboard 8 is connected to the main footboard 5, and the auxiliary footboard 8 is equipped with a third rolling wheel 7 that is pivotally connected to the free end opposite to the end connected to the main footboard 5 and supported by the third rail 4. . 8a is the upper surface of the auxiliary footboard 8, and 8b is a marker band provided on three sides of the upper surface 8a. Reference numeral 10 denotes a movable footboard consisting of a main footboard 5 and an auxiliary footboard 8. Many sets of these movable footboards 10 are arranged in an endless manner corresponding to the circulation path 1. 10a is the top surface of the movable footboard 10, and 10b is a sign indicating that the main footboard 5 and the auxiliary footboard 10 are connected as a pair. It is formed by.

11 is a lower entrance/exit, and 12 is an upper entrance/exit. The interval between the first rule 2 and the third rail 4 is determined so that the upper surface 8a of the auxiliary footboard 8 maintains a horizontal plane over the entire area from the lower entrance 11 to the upper entrance 12 on the outgoing path 1a of the circulation path 1. The upper surface 5a of the king tread 5 serves as an auxiliary tread 8 near the lower entrance 11 and the upper entrance 12 of the outbound path 1a of the circulation path 1.
The circulation path 1 is maintained horizontally to form the same plane as the upper surface 8a of the circulation path 1.
The distance between the first rule 2 and the second rail 3 is determined so that the end opposite to the connection part with the auxiliary footboard 8 is inclined slightly higher at the inclined part of the outgoing path 1a. Reference numeral 13 is a tread plate steel that holds the shaft of the third rolling wheel 9, connects the movable tread plate 10, and drives these. (Illustrated).

When the tread plate steel 13 is driven, the movable tread plate 10 has an upper surface 10& forming a horizontal surface near the lower entrance/exit 11 and upper entrance/exit 12, and the upper surface 10a forms a slightly dogleg shape at the inclined part of the escalator. and moves on the outward route 1a. Furthermore, by appropriately setting the lengths of the main footboard 5 and the auxiliary footboard 8 along the moving direction, it is possible to load vehicles such as wheelchairs. Furthermore, in the reversal section 1C of the circulation path 1, the auxiliary footboard 8 of the movable footboard 10 rotates relative to the main footboard 5, so that they pass through the reversal section 1C in a bent state.

In the escalator according to an embodiment of the present invention configured as described above, the upper surface 10a of the pair of movable treads 10 composed of the main tread 5 and the auxiliary tread 8 is upward.

Since a horizontal surface is formed in the vicinity of the lower entrance/exit 12.11, it is easy for vehicles such as wheelchairs to get on and off the upper surface of the movable footboard 10.

In the movable footboard 10, at the inclined part of the outgoing path 1a of the circulation path 1, the upper surface 5a of the main footboard 5 is low at the connecting part between the main footboard 5 and the auxiliary footboard 8, and the opposite end is sloped at a madder angle. Since the wheelchair or the like is urged by the auxiliary footboard 8, there is no fear that the wheelchair or the like will fall from the movable footboard 10.

As explained above, in the escalator tread according to the present invention, in which a pair of movable treads is composed of a main tread and an auxiliary tread, the upper surface of the main tread is connected to the auxiliary tread at least in the inclined part of the circulation path. Since the end opposite to the connecting part is tilted higher, vehicles such as wheelchairs riding on the movable tread are always urged toward the auxiliary tread, thereby preventing the vehicle from falling off the movable tread. This has the effect of making it possible to prevent accidents such as accidents caused by accident, and to realize a safe escalator.
