Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a structure that facilitates the manufacture of curved escalators, particularly those with a parapet deck formed in a spiral shape.

[Conventional technology]

For example, a curved escalator that is assumed to be similar to the conventional curved escalator shown in Japanese Utility Model Application Publication No. 59-83860 will be explained with reference to FIGS. 2 to 5.

In the figure, 1 is a main frame arranged at an angle and curved in the horizontal projection plane, 2 is a large number of steps connected to each other and arranged in the main frame 1 and operated in circulation, 3 is a main frame extending along the length of the main frame 1. A parapet erected along the edge, 4 is a skirt guard fixed to the main frame 1 and provided facing the side of the steps 2, 4a is shaped like angle iron and fixed to the upper edge of the skirt guard 4. A supporting member 4b is arranged longitudinally in the same manner as the supporting member 4a, and one side is fastened to the supporting member 4a and the other side is bent and extends toward the base of the balustrade 3. 5 is a receiving metal fitting. An outer deck 6 fixed to the main frame 1 and placed on the upper surface between the outer part of the main frame 1 and the base of the balustrade 3 has a flat cross section, one side is fixed to the base of the balustrade 3, and the other side has a receiving metal fitting 4b on the back side. an inner deck placed overlapping the upper surface;
7 is a longitudinal member which is fastened to the upper edge of the skirt guard 4 on one side and held by the metal fitting 4b on the other side to receive the edge of the inner deck 6, and is disposed longitudinally on the upper edge of the skirt guard 4. be.

That is, an inner deck 6 is provided between the steps 2 and the base of the parapet 3, which is inclined as a whole, curved in the horizontal projection plane, and also inclined in the cross section.

[Problem that the invention attempts to solve]

In the curved escalator as described above, the inner deck 6 has a curved and spirally twisted shape, and is designed to have a flat cross section in order to facilitate its manufacture. However, one of the edges of the inner deck 6 is supported by a receiving metal fitting 4b fastened to a supporting member 4a, and these supporting members 4a and receiving metal fitting 4b
Both of these two members require twisting and bending to match the length of the main frame 1, which increases production costs, and there is also the problem that it takes a lot of time and effort to mold the two members to fit each other without errors. Ta.

This invention is aimed at solving the above-mentioned problems, and is intended to provide a curved escalator that has a simple structure on the inner deck and can be easily manufactured.

[Means for solving problems]

In the curved escalator according to this invention, one side of the inner deck is fixed to the base of the balustrade, and the other side of the inner deck is directly supported by a supporting member longitudinally disposed at the upper edge of the skirt guard.

[Effect]

This design reduces the number of members that are twisted and bent to support the edges of the inner deck.

〔Example〕

An embodiment of this invention will be explained below with reference to FIG.

In the figure, the same reference numerals as in FIGS. 2 to 5 indicate corresponding parts, and 6 is arranged such that the edge on the step 2 side protrudes from the upper end of the support member 4a toward the step 2 side, and the back side of this edge is arranged on the support member 4a. A part of the inner deck 7 supported at the upper end is a longitudinal member fastened to the upper edge of the skirt guard 4 and arranged longitudinally along the skirt guard 4, and the other part is attached to the inner deck 6 on the step 2 side. It is arranged to cover the protrusion and its upper surface.

That is, the edge of the inner deck 6 on the step 2 side is directly supported and protruded by the support member 4a, and is held by the longitudinal member 7. For this reason, the inner deck 6
Since only the supporting member 4a is required, twisting and bending work is reduced, and the number of members is also reduced, so that manufacturing costs can be reduced. Further, since the edge of the inner deck 6 is arranged to protrude from the support member 4a, adjustment is possible even if the machining accuracy of the inner deck 6 and the support member 4a is poor, and there is no problem such as gaps between the skirt guard 4 and the support member 4a. The inner deck 6 can be assembled.

[Effect of idea]

As explained above, this invention provides a skirt guard with supporting members arranged longitudinally on the upper edge, and supports the back side of the inner deck, which is fixed to the base of the parapet on one side, by the upper end of the supporting member. The edge thus supported is held on the skirt guard by a longitudinal member. As a result, the edge of the inner deck on the step side is supported only by the supporting material, and the number of twisting and bending members is reduced, resulting in a curved escalator that can be manufactured at low cost and easily on the inner deck. be.
