Description

Specification

Passenger conveyor technology

The present invention relates to a passenger conveyor such as an Eskare overnight or an electric road. Background art

In general, a passenger conveyor is, for example, a main frame including left and right side frames and a horizontal member connecting the left and right side frames, as disclosed in Japanese Patent Application Laid-Open No. 3-124690. Are installed in a building, a plurality of treads connected endlessly and circulating, a balustrade standing upright at positions corresponding to both sides of these treads, and a periphery of the balustrade are moved within the main frame. Supports moving handrails.

The above-mentioned conventional technology does not give any consideration to reducing the installation space of the passenger conveyor.Therefore, even if the passenger conveyor that has been installed for about 20 years has been renewed, the passenger conveyor with the same step size must be installed. Was not obtained. Disclosure of the invention

An object of the present invention is to provide a passenger compare that can reduce an installation space, particularly an installation space in a width direction.

Another object of the present invention is to provide a passenger conveyor that can be installed within the same installation dimensions at the time of renewal and can be expanded in the width direction.

In order to achieve the above object, the present invention arranges the vertical projection of the side frame of the main frame and the moving handrail so that the vertical projection of the wheels of the tread plate overlaps with the moving handrail of the bracket. .

According to the above configuration, the left and right spaces which have conventionally existed between the both ends of the tread in the width direction and the side frame can be significantly reduced, and as a result, the passenger conveyor Can be reduced in the width direction.

The ability to reduce the width of the passenger conveyor in the width direction means that if the installation size is the same, there is room in the width direction, in other words, a tread with an expanded width can be used. In other words, the renewal can increase the transport capacity of the passenger contest. BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 is a cross-sectional view taken along the line II-II in FIG. 2 showing a main part of a passenger compare according to the present invention.

FIG. 2 is a schematic side view showing the entire passenger conveyor according to the present invention. BEST MODE FOR CARRYING OUT THE INVENTION

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Escale Night 1 has a main frame 2 installed over the upper floor U F and lower floor L F of the building. The main frame 2 has left and right side frames 3 and a horizontal member 4 connecting the side frames 3. The side frame 3 connects the upper chord material 5 extending in the longitudinal direction of the escare 1 and the lower chord material 6 located below the upper chord material 5 with an interval, and connects the upper chord material 5 and the lower chord material. It is constituted by a vertical member 7. In the main frame 2 configured as described above, guide rails 8 for guiding a step described later are fixed to both inner sides of the main frame 2. The step 9 is composed of a step frame 10 and a step board 11 fixed to the step frame 10 horizontally, and a pair of front wheels 12 protruding from both ends of the step step 10 in the width direction. It has wheels consisting of rear wheels 13. These wheels roll on the guide rail 7 and travel on the outward path so that the tread plate 11 always keeps its level.

A balustrade 14 is erected above the left and right side frame members 3 via fixing members. The balustrade 14 is a balustrade panel made of tempered glass panels, for example. 5, a handrail frame 16 fixed to the periphery of the balustrade panel 15, and an endless moving handrail 17 movably guided by the handrail frame 16, and a base of the balustrade panel 15. The inner deck cover 18 and outer deck cover 19 are covered. From the lower part of the inner deck cover 18, a skirt guard 2 ◦ which vertically separates the inner side of the inner deck force par 18 and the outer deck cover 19 from the end of the step 9 extends vertically. In addition, the moving handrail 17 is turned at one end of both ends in the longitudinal direction of the balustrade 14 and enters the inside of the inner deck cover 18 and the outer deck cover 19, and the two ends of the longitudinal end of the balustrade 14 are On the other side, they appear outside the inner deck cover 18 and the outer deck cover 19. The moving handrail 17 travels outside the inner deck cover 18 and the outer deck cover 19 as a forward path, and travels inside the inner deck cover 18 and the outer deck cover 19 as a return path.

The step 9 has a shaft of the front wheel 12 connected to a step chain 21. The step chain 21 is wound around a drive sprocket 22 pivotally supported in an upper machine room of the main frame 2. The frame 2 is wound around a driven wheel 23 supported in a lower machine room. The driving sprocket 22 is transmitted with a rotational force by a driving machine 24 installed in the vicinity.

In the Escalé 1 of the above configuration, the moving handrail 17 is arranged so that the vertical projection of the moving handrail 17 overlaps the side frame 3 in the direction along the width of the step 9 by the L dimension. Then, the wheels of the steps 8, in particular, the front wheels 12 are arranged so that the vertical projections overlap. The moving handrail 17 whose vertical projection overlaps the side frame 3 is a moving handrail 17 that travels at least on the return side.

More specifically, a step 7A is formed on the upper part of the vertical member 7 so that the vertical projection of the moving handrail 17 overlaps with the step width of the upper chord material 5 of the side frame 3, so that the moving handrail 17 Avoid interference. In addition, the front wheel 12 of the step is moved closer to the moving handrail 17 arranged as described above in the direction along the step width, and furthermore, the vertical projection is overlapped, so that the end of the step 9 is on the side. Approach the frame side. However, move the front wheel 1 2 closer to the side frame 3 than the center of the moving handrail 17. L. If the vertical projections are overlapped so as to shift the dimension, the end of the step 9 will be closer to the side frame 3 side.

As described above, according to the present embodiment, the moving handrail 17 can be moved toward the side frame 3, so that the moving handrail 17 on the return side inside the inner deck cover 18 and the outer deck cover 19 can be provided. The skirt guard 20 can be made closer to the skirt guard 20 by shifting the center of the front wheel 12 of the step 9 toward the side frame 3 side from the center of the moving handrail 17. The widthwise end of the step 9 can be brought close to the step.

As a result, if the width of the steps 9 is the same as the conventional one, it is possible to reduce the installation width of the Escalée 11.

The Escalée, which has been around for about 20 years after installation, has been designed with ample room for its internal configuration, so when renewing it, it has the same installation width but a large step width. If the step width of the escalator is 100 リ, the renewal escalation with a step width of 1200 MM can be installed every night, and the transportation capacity can be improved.

In the above embodiment, the passenger conveyor was described as an example of the Escalée one day, but the present invention is naturally applicable to an electric road that has the same basic configuration as the Escalée one and does not generate a step between the treads. . Industrial applicability

As described above, according to the present invention, it is possible to reduce the installation space, particularly the installation space in the width direction, and to obtain a passenger conveyor that can be installed in the same installation dimensions and can be expanded in the width direction during renewal. it can.
