  However, since the one described in Patent Document 1 has a cantilever structure in which one end of a substantially U-shaped fence is fixed to a transparent balustrade such as a glass panel, there is a problem in securing rigidity. In other words, from the viewpoint of safety, it is expected that not only things but also passengers such as children and drinkers will fall to the outside of the railing by the fence, but the rigidity that supports the passenger is added to the support part of the fence It was difficult to prepare. Furthermore, the thing of patent document 1 was also a structure difficult to apply to the panel-type balustrade where the dimension between the height direction of a handrail frame and an outer deck is small.

  Moreover, since the thing of patent document 2 is a structure which attaches a fence to the support | pillar standingly arranged by the side part of the main body frame, a fence cannot be arrange | positioned in a passenger conveyor width | variety, It was the structure which a big clearance gap produced between them. For this reason, in addition to the possibility of passengers such as drinkers leaning on the railing being caught in the gap, it was difficult to save space. Moreover, when it was going to add a fence to the existing passenger conveyor, the subject that the large-scale operation | work which fixes a support | pillar to a main body frame was needed also occurred.

  An object of the present invention is to provide a passenger conveyor that can increase the rigidity of a fence installed outside the balustrade and can be arranged closer to the balustrade, regardless of whether the fence is newly installed.

In order to solve the above-mentioned problems and achieve the object of the present invention, a passenger conveyor according to the present invention is connected endlessly to a plurality of steps that move between entrances and exits in the direction of travel of the plurality of steps. A plurality of pillars fixed to the main body frame, a balustrade panel and handrail frame supported by the plurality of pillars, a balustrade having an outer deck that covers the side of the handrail frame, and a handrail above the balustrade A moving handrail attached via a frame and moving in synchronization with the steps, and a fence disposed outside the balustrade, the fence being disposed in a vertical projection plane of the outer deck At the same time, its lower end is fixed to the outer deck with a fixing bracket on the vertical projection plane of the column installation position.

  According to the passenger conveyor of the said structure, the fence installed in the outer side of a railing can be made into a thing with high rigidity irrespective of the new installation, and can be arrange | positioned in a passenger conveyor width | variety.

  Problems, configurations, and effects other than those described above will be clarified by the description of the following examples.

It is a whole lineblock diagram showing the passenger conveyor concerning one example. It is sectional drawing which shows the structural example of the balustrade and fence which concerns on one Example. It is a top view which shows the structural example of the fence which concerns on one Example.

  Hereinafter, the form for implementing the passenger conveyor of this invention is demonstrated with reference to FIGS. 1-3. In the drawings, the same or similar components are denoted by the same reference numerals, and repeated description is omitted.

  FIG. 1 is an overall configuration diagram showing a passenger conveyor according to an embodiment of the present invention. This passenger conveyor is an ascending escalator 1 installed between different floors. In the drawing, the traveling direction is indicated by x, the width direction is indicated by y, and the vertical direction is indicated by z. The escalator 1 is constructed between a lower floor and an upper floor, and has a lower horizontal portion 2a extending toward the lower floor, an upper horizontal portion 2b extending toward the upper floor, and a lower horizontal portion. A main body frame 2 having an inclined portion 2c formed between the portion 2a and the upper horizontal portion 2b; The balustrades 6 provided on the lateral sides of these steps 5, the handrails 7 attached to the periphery of the balustrades 6 and moving in the same direction in synchronization with the steps 5, And a fence 8 disposed on the outside. In FIG. 1, the outline shape and positions of the plurality of pillars 11 provided inside the balustrade 6 are illustrated by omitting the illustration of the exterior plate 13 described later.

  FIG. 2 is a cross-sectional view showing a configuration example of the balustrade 6 and the fence 8 on one side at the position AA in FIG. FIG. 3 is a top view showing a configuration example of the moving handrail 7 and the fence 8 on one side as seen from the direction B of FIG.

  As shown in FIG. 2, the balustrade 6 includes a pillar 11, a balustrade panel 12 supported by the pillar 11, a handrail frame 16, an outer deck 14 covering between the handrail frame 16 and the exterior plate 13, and a balustrade panel 12. It has an inner deck 15 that covers the space between the inner lower part and step 5.

  The moving handrail 7 is movably attached via a handrail frame 16 fixed to the upper end of the balustrade panel 12.

  And the escalator 1 of a present Example is devised in order to make the fence 8 installed in the outer side of the balustrade within the passenger conveyor width W2 and to have high rigidity irrespective of the new installation. Yes. Specifically, the lower end of the fence 8 is fixed to the outer deck 14 by a fence fixing bracket 21 installed on the vertical projection surface of the column 11, and is disposed within the vertical projection surface of the outer deck 14.

  The fence fixing bracket 21 rises as a pair from the horizontal portion 21b attached to the upper surface of the outer deck 14 by the fixing bolt 21a, and the lower end portion of the fence 8 is inserted, and the fence is fixed by the fixing bolt 21c. And a sandwiching portion 21d for sandwiching the lower end portion of 8.

  In the fence 8, the height dimension is set so that the height dimension H1 from the tread surface of the step 5 to the upper end of the fence is larger than the standard adult height of about 170 cm. Further, the fixing position of the fence fixing bracket 21 is set so that the gap dimension W1 between the moving handrail 7 and the fence 8 is smaller than a standard adult body width (specifically, about 60 to 100 mm). Is set. The upper end portion 8a of the fence 8 may be vertical or may have a shape that is rounded toward the outside.

  In the present embodiment, for example, when the fence 8 is to be added to the existing escalator 1, first, the balustrade panel 12 is removed from the escalator 1, the attachment position of the pillar 11 is confirmed, and the attachment position of the pillar 11 is confirmed. The fence fixing bracket 21 is attached to the outer deck 14 on the vertical projection plane. That is, the fixing bolt 21a is fixed in a state where the horizontal portion 21b of the fence fixing bracket 21 is opposed to the upper surface of the outer deck 14 at the position of the column 11 having high rigidity.

  Next, the lower end of the fence 8 is fixed by the fence fixing bracket 21. That is, the lower end portion of the fence 8 is inserted into the clamping portion 21d of the fence fixing bracket 21, and the fixing bolt 21c is fastened and fixed in this state.

  When the escalator 1 is operated with the fence 8 attached in this manner, the height dimension H1 from the tread surface of the step 5 to the upper end of the fence is larger than the standard adult height, Even if a passenger, such as a drinker, gets on the railing 6, the fence 8 is prevented from getting outside. At this time, although a relatively large load is applied to the fence 8 due to the pressing by the passenger, the lower end of the fence 8 is fixed by the fence fixing bracket 21, and the fence fixing bracket is on the vertical projection plane of the mounting position of the column 11. Since it is the most rigid position, it can sufficiently withstand the load. In addition, since the gap dimension W1 between the moving handrail 7 and the fence 8 is smaller than the standard adult body width, the passenger's space between the fence 8 and the moving handrail 7 that is a moving object. The risk of getting caught by the body can be reduced.

  According to the present embodiment, since the lower end of the fence 8 is fixed to the outer deck 14 by the fence fixing bracket 21 at a portion having high rigidity, the high-rigid fence 8 is moved to the moving handrail 7 regardless of the existing construction. It can be installed in close proximity to each other and can reliably function as a fence for preventing passengers from falling and getting caught.

  Moreover, the fence 8 can be arrange | positioned in the passenger conveyor width W2 by arrange | positioning in the vertical projection surface of the outer deck 14, and space saving can be achieved.

  In the above, the Example of the passenger conveyor of this invention was demonstrated including the effect. However, the passenger conveyor of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the invention described in the claims.
