Description

[Detailed description of the invention] This invention relates to the structure of an escalator.

Conventional escalators are intended for transporting people, and the steps are usually manufactured to have a depth of about 40 centimeters.

For this reason, it is not possible to transport vehicles such as baby carriages, shopping cards, wheelchairs, etc. that accompany the movement of people, and the escalator has a drawback that its uses are limited.

Further, in order to enable transportation of vehicles, it is possible to increase the depth of the steps in conventional escalators.

However, because the steps are deep, the radius of the chain gear device that reverses the steps becomes large, and the S-force rake body that accommodates them becomes large, which limits the installation space. .

The present invention aims to solve the above-mentioned drawbacks, and provides an escalator that can transport vehicles such as baby carriages and is compact.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 4.

In the figure, 1 is the circulation path of the escalator, and the inclined outward path 1a
, a return route 1b, and a reversing portion 1c at the connecting portion between the two, first rails 2 disposed on both sides, and a second rail 3 disposed below the first rail 2 on the outbound route 1a. , a third rail 4.

5 is a main tread, which is pivoted on one side and connects to the first rail 2.
The first roller 6 is supported by the first roller 6, and the second roller 7 is disposed on the other side, projects downward from the first roller 6, is pivoted and supported by the second rail 3, and is horizontal on the outward path 1a. It is located in

Reference numeral 8 denotes an auxiliary footboard pivotally attached to the upper edge of the outgoing path 1a of the main footboard 5, which is equipped with a third roller 9 pivotally supported at the free end and supported by the third rail 4; 5 is placed on the same horizontal plane.

10 is a moving step consisting of a main step 5 and an auxiliary step 8; 11 is a step chain that holds the shaft of the third wheel 9, connects and drives the moving steps 10; It is wrapped around a chain wheel (not shown).

That is, when the step chain 11 is driven, the moving step 1
0 moves on the outward path 1a while maintaining the horizontal state.

By appropriately setting the lengths of the main footboard 5 and the auxiliary footboard 8 along the moving direction, it becomes possible to load vehicles.

Further, by appropriately setting the inclination angle of the outbound path 1a, the step difference of the movable step 10 can be made similar to that of a normal escalator.

And the dangers caused by large steps are eliminated.

Then, at the reversal section 1c of the circulation path 1, the moving step 1
0, the auxiliary footboard 8 rotates with respect to the main footboard 5.

Then, it passes through the reversing section 1c in a refracted state.

Therefore, the radius of the reversing portion 1c and the step chain gear etc. disposed in this portion can be made small.

Therefore, the body of the escalator that accommodates these can be downsized, and restrictions on the installation location can be eliminated.

As explained above, in the present invention, the movable step is configured to be bendable about a line horizontally orthogonal to the direction of movement, and the depth of the movable step is set to a size that allows for loading of vehicles.

As a result, the radius of the member that reverses the moving steps can be made smaller, and the body of the escalator can be made smaller, realizing an escalator that can transport vehicles and has fewer restrictions on where it can be installed. be.
