Description

[Detailed Description of the Invention] This invention relates to an improvement of an escalator composed of mutually articulated steps.

Escalators are intended for the transportation of general passengers, and the depth of the steps is approximately 40 cm. For this reason, transporting vehicles such as baby carriages and shopping carts accompanying wheelchair users and passengers is fraught with danger. Therefore, for example,
As shown in Japanese Patent No. 139083, it has been proposed that one step is composed of a main step and a secondary step, and has a longer depth dimension. This is shown in FIGS. 1 and 2.

In the figure, 1 is the truss of the escalator, 2 is the circulation path set in the truss 1, 2a is the outgoing path in the circulation path 2, 2b is also the return path, and 2c is the outgoing path 2a and the return path 2.
3 is the first rail arranged along the circulation path 2, 4 is also the second rail, and 5 is also the inverted part constituting the connection part of b, the first rail arranged along the circulation path 2a, A third rail located above,
6 is a main step, 7 is a secondary step arranged adjacent to the main step 6, 8 is a movable step consisting of the main step 6 and secondary step 7, and 9 is provided on the back side of the main step 6 and secondary step 7, and connects them both. 10 is a first wheel that is attached to the upper end of the main step 6 and rolls on the first rail 3; 11 is a second wheel that is attached to the lower end of the secondary step 7 and rolls on the second rail 4; 12 is a hinge that is attached to the lower end of the secondary step 7 and rolls on the second rail 4; The third
The third wheel rolling on the rail 5, 13, is the first wheel of all
A step chain 14 is connected to the shaft of the wheel 10, connects the moving steps 8, and is driven by an electric motor (not shown). Reference numeral 14 designates handrails erected on both sides of the moving steps 8.

That is, when the step chain 13 is driven, the upper surfaces of the main step 6 and the secondary step 7 move on the outward path 2a while forming the same horizontal plane. By setting the depth dimensions of the main step 6 and the secondary step 7 to approximately 80 cm, it becomes possible to load vehicles. In addition, the reversing section 2c
Here, the main step 6 and the secondary step 7 rotate around the hinge 9, and the movable step 8 passes through the reversing section 2c in a bent state.

However, a dedicated hinge 9 is required to connect the main step 6 and the secondary step 7, making the structure complicated. Therefore, it is inevitable that the failure rate will increase.

This idea improves the above-mentioned problems, and has a simple structure by attaching the third wheel to both the main step and the secondary step, and locating its axis directly below the joint between the main step and the secondary step. To provide an articulated step escalator that can be produced at low cost and has a low failure rate.

An embodiment of this invention will be described below with reference to FIGS. 3 to 6.

In the figure, 6a is a main bracket that supports the main step 6, 7a is a sub bracket that supports the secondary step 7, 1
A first shaft 5 is detachably supported at the upper end of the main bracket 6a by a support 16 and a countersunk screw 17, and a first wheel 10 is pivotally attached to both ends of the shaft, forming a through shaft. Reference numeral 5 is a first shaft supported at the lower end of the secondary bracket 7a. A second shaft 19 with a second wheel 11 attached to its end is supported in common by the lower end of the main bracket 6a and the upper end of the subordinate bracket 7a, and the third wheel 12 is attached to both ends thereof. and a third shaft 20 which is disposed directly below the joint A of the footstep 7 and forms a through shaft; 20 is a skirt plate forming the lower edge of the parapet 14; Other than the above, the configuration is the same as in FIGS. 1 and 2.

That is, since the third shaft 19 is commonly supported by the main bracket 6a and the sub-bracket 7a, no special hinge 9 is required, and the structure is simple, the failure rate is low, and the construction can be made at low cost. In addition, since the third shaft 19 is located directly below the joint A between the main step 6 and the secondary step 7, even if a load is applied to the moving step 8, the stability of the main step 6 and the secondary step 7 is good. be.

Note that the operation of this embodiment is exactly the same as that described above.

Further, when one set of movable steps 8 is removed from the first shaft 15 and the main steps 6 are rotated about the third shaft 19, they are folded neatly as shown in FIG. If a band is attached to this, it can be conveniently carried, stacked, etc., so that work such as installation and maintenance can be carried out efficiently. Note that B in the figure indicates the loading surface. At this time, the distance between the first shaft 15 and the third shaft 19
If L ₁ and the distance L ₂ between the third shaft 19 and the second shaft 18 are made equal, and the second shaft 18 is made to be a shaft that protrudes a little inward or is made into a single shaft, the result will be as shown in Fig. 6. When folded up, the second shaft 18 can be attached to the main bracket 6a using the support 16 and the countersunk screw 17. In this way, packing materials such as bands and special devices for preventing stacks from collapsing are not required.

Note that the second shaft 18 may be a single through shaft as described above, and conversely, the third shaft 19 may be a split shaft with separate shafts on both sides.

As explained above, in this design, the movable step is composed of a main step and a secondary step, which are commonly pivoted to a third axis, and this third axis is placed directly below the joint between the main step and the secondary step. Therefore, the main step and the secondary step can be connected without using a dedicated hinge, and an articulated step escalator that has a simple structure, can be manufactured at low cost, and has a low failure rate can be constructed.
