Description

Specification

Passenger conveyor technology

The present invention relates to a passenger conveyor such as an escalator and an electric road, and more particularly to a passenger conveyor having an improved shape of an inner deck cover covering a balustrade panel. Background art

Generally, at the base of a passenger conveyor, for example, a balustrade panel of an electric road, a tread side is provided so as to cover a space between a vertical guard and a balustrade panel, which is vertically arranged opposite a side edge of the tread. It has an inner deck cover that slopes down toward you.

A similar configuration is disclosed in, for example, Japanese Patent Application Laid-Open No. H10-172254. In general, the inner deck cover generally has a width between the skirt guard and the balustrade panel of about 100 cm or less, and a slope is formed within the width to form a slope on the surface. They are trying to prevent them from walking on foot or climbing on their shopping power.

However, according to the Building Standards Law revised in June 2012 (Enforcement Order Article 129-12), the upper limit of the step width and the width of the moving handrail are set, and while each is widened, The width between the skirt guard and the balustrade panel, that is, the width equivalent to the inner deck cover is 250 thighs, which is 2.5 times wider than before.

Widening of the inner deck cover increases the space for passengers to use, and there is less opportunity for baggage to come in contact with the balustrade panel even if baggage, etc. is held on the balustrade panel side. It has the advantage of disappearing.

However, when widening the inner deck cover, it is common practice to simply widen the slope of the inner deck cover in the horizontal direction. In this case, however, the angle of inclination of the inner deck cover becomes inevitable. As a result, not only safety is reduced due to the ease with which feet and force can ride, but also the strength problem of deformation (sinking) of the inner deck cover itself and deformation damage due to load is caused. Was desired. Disclosure of the invention

SUMMARY OF THE INVENTION An object of the present invention is to provide a passenger conveyor in which the safety and inner deck cover strength are not reduced even by widening the inner deck cover.

In order to achieve the above object, according to the present invention, a step portion is formed on the inner deck cover that is inclined so as to become lower toward the tread side, toward the tread side.

According to the above configuration, even if feet are placed on the inner deck cover, the sense of stability is reduced by the steps on the surface of the inner deck cover, so that the feet are lowered from above the inner deck cover. Can contribute to the improvement of safety. In addition, the formation of a plurality of steps increases the rigidity of the inner deck cover and improves the strength, thereby contributing to prevention of deformation of the inner deck cover, deformation due to load, and breakage.

Hereinafter, a first embodiment of a passenger conveyor according to the present invention will be described along the electric road shown in FIG. 1 and FIG.

Electric road 1 has a plurality of step boards 3 of the width of moving is coupled from one entrance 2 to the other entrance (not shown) is over endless, erected at intervals W ₂ along both sides of the tread plate column A pair of balustrade panels 4, a moving handrail 5 guided by the periphery of the balustrade panels 4 and synchronously moving with the treads 3, and a skirt vertically arranged facing the side end 3 A of the treads 3 A guard 6, an inner deck cover 7 that covers the base of the balustrade panel 4 and blocks between the balustrade panel 4 and the skirt guard 6, a frame 8 that holds the strength of these components, etc. Has been established.

The tread plate 3 supports a running wheel 9 composed of a pair of front wheels and a pair of rear wheels so as to protrude from the side end 3 A, and the running wheel 9 is attached to the frame body 8. Rolls on the fixed guide rail 10. Further, the skirt guard 6 is supported by a support member 11 fixed to the frame 8. The outside of the base of the balustrade panel 4 (the side opposite to the treadboard) is covered with an outer deck cover 12, and an outer cover 13 is provided so as to cover the outside of the frame 8 as necessary.

The base of the drying panel 4 is held by a holder 14 supported by a frame 8 such that the ends of the inner deck cover and the outer deck cover 12 engage with the holder 14. I have to. The balustrade panel 4 may be made of a glass panel or a transparent material in the case of a transparent balustrade, and may be made of a metal material or a design material in the case of an opaque balustrade. The present invention can also be applied to a passenger conveyor equipped with such a type of drying panel.

Here, the inner deck cover 7 is substantially the same as a small flat surface portion 7A for engaging with the holding body 14 on the balustrade panel 4 side, and is inclined downward from the small flat surface portion 7A toward the tread plate 3 side. Two inclined surfaces 7 B and 7 C having a slope, a vertical surface 7 D forming a step at the boundary between the inclined surfaces 7 B and 7 C, and a slope formed at the lower end and parallel to the skirt guard 6 It has a fixed portion 7E, which is formed by bending a single plate and integrally forming it. By fixing the fixing portion 7E at the lower end of the slope to the support member 11 together with the skirt guard 6 with a screw or the like, an inner deck cover 7 provides a space between the base of the balustrade panel 4 and the skirt guard 6. Will be blocked.

With the above configuration, if the foot is placed on the surface of the inclined surface 7B of the inner deck cover 7, the inclined length of the inclined surface 7B is shortened by the vertical surface 7D. The foot does not stay stably on the inclined surface 7B, but slides down the inclined surfaces 7B and 7C one by one to reach the leg plate 3, which is the normal riding position, and walks on the inner deck cover-7. This is no longer the case, and safe use can be provided.

Furthermore, since the inner deck cover 7 has a vertical surface at the boundary between the inclined surfaces 7B and 7C, the strength of the inner deck cover 7 increases due to the beam effect in the longitudinal direction of the cross section, and the inner deck cover 7 itself bends. The load applied to the surface of the inner deck cover 17 can be prevented from being deformed or damaged by preventing passengers from hitting, or putting passengers on or hitting baggage.

In the inner deck cover 7 having the above-described structure, the formation of the vertical surface 7D provides a reinforcing portion at the boundary between the adjacent inclined surfaces, and the stepped portion facing the tread side between the inclined surfaces 7B and 7C. As a result, the inclined surfaces 7 B and 7 C become a plurality of inclined surfaces, and the vertical surface 7 D serves as a means for preventing the inner deck cover 7 from bending in the inclined direction, and the inclined surfaces 7 B and 7 C In combination with the vertical plane 7D, when a passenger puts or places his or her feet or luggage, it also acts as a means of obstruction that acts to slide down without staying there.

The first embodiment according to the present invention is an inner deck cover 7 in which two inclined surfaces 7 B and 7 C having substantially the same gradient and one vertical surface 7 D provided at the boundary thereof are formed. Based on the configuration, the same effects can be obtained in the second to fourth embodiments shown in FIGS. 3 to 5.

That is, the deck cover 15 according to the second embodiment shown in FIG. 3 has three inclined surfaces 15 E to 15 D having substantially the same gradient, and a step formed at the boundary between the inclined surfaces. It has three vertical surfaces 15E and 15F, and the other configuration is the same as that of the first embodiment.

According to this configuration, the length of each inclined surface is further increased as compared with the first embodiment. Therefore, the foot becomes more difficult to put on, and the vertical planes 15E and 15F can further improve the beam effect in the vertical section. The inner deck cover 16 according to the third embodiment shown in FIG. 4 has three slopes 16 B to 16 D having substantially the same slope and a step at the boundary between the slopes. Therefore, it has two inclined surfaces 16E and 16F with small inverse gradients, and the other configuration is the same as that of the first embodiment.

According to this configuration, the same effects as in the first and second embodiments can be obtained.

In Fig. 1, Fig. 3, and Fig. 4, the slopes have almost the same slope, but the slopes are formed by combining slopes with different slopes and shapes. Is also good.

The inner deck cover 17 according to the fourth embodiment shown in FIG. 5 has two inclined surfaces 17A and 17B, and a vertical surface 17C forming a step is provided at the boundary between the two inclined surfaces. In this respect, the configuration is the same as that of the first embodiment except that the inclined surface 17A on the balustrade panel 4 side of the two inclined surfaces 17A and 17B is curved so as to protrude toward the front side. In that the remaining skirt guard 6 side slope 17 B is a flat slope.

By forming the curved inclined surface 17 A, the instability when the passenger puts his foot can be emphasized, and the function can be exhibited as a means of obstacles for passengers. Furthermore, as shown by the two-dot chain line, the danger can be further emphasized by steepening the slope of the slope 17A toward the skirt guard, thereby increasing the risk of passengers' feet This can cause hesitation. In FIG. 5, the curved inclined surface 17A may be formed as a flat inclined surface, and the flat inclined surface 17B may be formed as a curved inclined surface.

In each of the above embodiments, the inner deck cover has a plurality of inclined surfaces and inclined surfaces. Although it is a combination of deformations, it is not limited to a combination of inclined surfaces and the like, but as in the fifth embodiment shown in FIG. 6, the side panel 4 of the inner deck cover 18 and the skirt guard 6 side Steps 18 A or irregularities may be formed in the entire area or a part of the area to restrict passengers from riding on the inner deck cover 18 ±.

Each of the inner deck covers 7, 15 to 18 described above is formed by bending a single plate to form an inclined surface, a stepped portion, or an uneven portion, but the inner deck cover is formed by a single plate. It is not essential, for example, as in the sixth embodiment shown in FIG. 7, the upper inner deck cover 20 on the balustrade panel 4 side and the lower inner deck cover 21 on the scout guard 6 side. Alternatively, a split type inner deck cover 19 composed of the following may be used.

The inner deck cover 19 shown in FIG. 7 will be specifically described. Each of the upper inner deck cover 20 and the lower inner deck cover 21 may be used alone or in combination with the above-described inclined surface, convex curved surface, stepped portion, uneven portion, etc. on the inclined surface which becomes lower toward the skirt guard 6 side. It is formed. The boundary between the upper inner deck power bar 20 and the lower inner deck cover 21 is provided at a position offset from the running wheel 9 of the tread plate 3 toward the L-size balustrade panel 4. At that position, in addition to the support member 11 described with reference to FIG. 1, a support member 22 fixed to the frame 8 is provided, and the support member 22 has an inclined lower end portion of the upper inner deck force par 20. Is fixed with screws or screws. An edge 23 is fixed to the support member 22, and an upper end of the lower inner deck cover 21 is fixed to the edge 23. The lower end of the lower inner deck cover 21 is fixed to the support member 11 as in FIG. The inclined lower end of the upper inner deck cover 20 and the inclined upper end of the lower inner deck cover 21 may be fastened and fixed to the support member 22 together. With the above structure, passengers can be made to recognize that they cannot put their feet on the surface of the inner deck cover 19, and the strength of the inner deck cover 19 can be increased. Thus, there is an effect that the maintenance inspection work of the rotating system of the electric road can be easily performed. That is, the boundary between the upper inner deck cover 20 and the lower inner deck cover 21 is located at a position offset from the running wheel 9 of the tread plate 3 toward the L-sized balustrade panel 4, so that, for example, the tread plate 3 is endless. When inspecting the tread chain (not shown) and the running wheels 9 of the tread 3, etc., release the fixing of the lower inner deck cover 21 to the edge 23 and the supporting member 11 and lower the inner deck cover. By removing 21 as shown by the two-dot chain line, the periphery of the tread chain ゃ traveling wheel 9 can be opened, and maintenance and inspection can be performed from the tread 3 or the entrance 2.

As described above, in the present embodiment, the inner deck cover is provided with a plurality of inclined surfaces, a plurality of non-horizontal planes, a plurality of irregularities, a step, or a mounting obstacle means, or By combining and forming the inner deck cover, even if the inner deck cover is widened, it is possible to restrict passengers from riding on the inner deck cover, and by forming them, or by providing the support member 22, the inner deck cover is provided. The strength of the cover can be secured.

The seventh embodiment shown in FIG. 8 has a configuration in which the inner deck cover 24 is divided into, for example, two in the inclination direction, and the upper inner deck cover 25 and the lower inner deck cover 26 have substantially the same cross-sectional shape. The cross-sectional shape of the board was designed so that The deck cover 25 includes, from the upper end, an upper vertical portion 25a, followed by an upper horizontal portion 25b, an inclined portion 25c, an intermediate vertical portion 25d, and a lower horizontal portion 25e. , A bent product of a plate having a lower vertical portion 25 f, and the lower inner deck cover 26 is also Have an upper vertical portion 26a, an upper horizontal portion 26b, an inclined portion 26c, an intermediate vertical portion 26d, a lower inclined portion 26e, and a lower vertical portion 26f. It is a bent product of a sheet material. However, the difference between the lower inner deck cover 26 and the upper inner deck cover 25 is that a portion corresponding to the lower horizontal portion 25 e of the upper inner deck cover 25 is a lower inclined portion 26 e. It is. The reason for forming the lower inclined portion 26e on the lower inner deck cover 26 in this way is that this position is one of the parts closest to the passenger's feet, and the intermediate vertical part is located at such a position. If a right angle is formed between the lower vertical part and the middle vertical part 26 d, there is a danger of injuring passengers at the right angle. 6 e was formed.

In this way, even if there are different parts in the cross-sectional shape of the upper inner deck cover 25 and the lower inner deck cover 26, the bending angle can be easily changed only by changing the pressing stroke during bending by the molding machine. It has the advantage that molding can be performed using the same molding machine.

From the above, the fact that the upper inner deck cover 25 and the lower inner deck cover 26 have almost the same cross-sectional shape means that the cross-sectional shape can be easily handled simply by changing the pressing stroke of the molding machine. The difference is included. Next, the eighth embodiment shown in FIG. 9 detects the external force, for example, when the passenger places his / her feet or luggage on the inner deck cover 17, and detects that the inner deck cover 7 bends, and pays attention. It encourages and issues alarms to increase safety.

Displacement detecting means 27 is opposed to the rear surface of the intermediate portion in the inclined direction which is easily bent by the external force of the inner deck cover 17. As the displacement detecting means 27, for example, a known detector such as a microswitch is used. The detection signal from the displacement detection means 27 is guided to the signal processing device 28, and the detection signal continues for a predetermined time. In this case, it is deemed that a passenger or the like is on the inner deck cover 17 and the speaker 29 alerts the user with automatic sound, or if the detection signal continues for a predetermined time, Activate the surveillance camera 30 to check the detection signal generation status on the monitor 31 in the surveillance room to determine whether it is a signal detection due to personal injury or an accident, and call the attention directly with the microphone 32 It is designed to guide accident handling.

Such monitoring provided with the displacement detecting means 27 may be used alone or in combination with the above embodiment.

Although each of the above embodiments has been described by taking an electric road as an example, the present invention can also be applied to an escalator, which is an inclined passenger conveyor. In that case, the step board may be replaced with the step in each embodiment.

As described above, according to the present invention, it is possible to obtain a passenger conveyor that does not decrease in safety or strength even when the inner deck cover is widened.
