In this embodiment, the escalator 1 will be described as an example of a passenger conveyor to which the balustrade device is applied. The passenger conveyor to which the balustrade device is applied is not limited to the escalator, and may be, for example, a moving walkway or the like.

As shown in FIG. 1, the escalator 1 includes a truss structure 2 and a plurality of steps 3. The truss structure 2 is a main frame arranged along the passenger transport direction of the escalator 1. The plurality of steps 3 are connected in an endless manner and are supported by the truss structure 2. Each step 3 is circulated and moved by the driving force of a driving machine (not shown) installed in the truss structure 2.

A pair of balustrade devices 10 are provided on the truss structure 2. Each of the balustrade devices 10 is erected on both sides of the truss structure 2 in the width direction along the passenger transport direction described above. Each balustrade device 10 is provided with a moving handrail 11. The moving handrail 11 is movably supported along the outer peripheral edge of the balustrade device 10. The moving handrail 11 is moved in synchronization with the step 3 by the driving force of the driving machine described above.

The balustrade device 10 includes a plurality of balustrade panels 12, a plurality of panel holders 100, and a deck device 20. The balustrade panel 12 is made of glass, for example. The plurality of balustrade panels 12 are arranged along the passenger transport direction described above. The lower part of each balustrade panel 12 is held by the panel holder 100.

As shown in FIG. 2, each panel holder 100 is provided separately from the truss structure 2 and is fixed to the truss structure 2 via a fixing member 30. The deck device 20 includes an inner deck board 21 and an outer deck board 22 shown in FIG. The inner deck board 21 is arranged on the step 3 side of the balustrade panel 12, that is, inside the escalator with respect to the balustrade panel 12. The outer deck board 22 is arranged on the side opposite to the step 3 of the balustrade panel 12, that is, outside the escalator with respect to the balustrade panel 12.

A skirt guard (not shown) is connected to the lower end of the inner deck board. The skirt guard is arranged so as to face the side surface of the step 3. The deck device 20 is fixed to the truss structure 2 via a support member (not shown). The deck device 20 configured as described above covers the space existing under the balustrade panel 12. The gap between each of the inner deck board 21 and the outer deck board 22 and the side surface of the balustrade panel 12 is closed by the packing 23. In the illustrated example, a sheet is sandwiched between the lower part of the balustrade panel 12 and the panel holder 100. This sheet is a cushioning material that prevents damage to the balustrade panel 12. The sheet is made of, for example, plastic resin, silicone resin, rubber or the like.

As shown in FIGS. 3 to 5, the panel holder 100 includes a holder main body 110, a holding member 120, and a bolt 130. The holder body 110 is made of steel. As shown in FIGS. 6 and 7, a fixing elongated hole 111 is formed in the holder main body 110. Then, as shown in FIGS. 3 and 4, the holder main body 110 is fixed to the fixing member 30 by the fastener 31 passed through the fixing elongated hole 111. The fastener 31 is, for example, a bolt and a nut. As shown in FIG. 2, the fixing member 30 is fixed to the truss structure 2. In this way, the holder body 110 is fixed to the truss structure 2 via the fixing member 30.

The fixing member 30 is attached to the truss structure 2 so that its position and orientation can be adjusted. Further, the position and orientation of attaching the holder main body 110 to the fixing member 30 can also be adjusted by, for example, changing the fastening position of the fastener 31 in the fixing elongated hole 111. By making full use of these adjustment mechanisms, the height, horizontal position, inclination, etc. of the balustrade panel 12 can be adjusted, and the balustrade panel 12 can be adjusted so as to be parallel to the passenger transport direction described above.

As shown in FIGS. 6 to 8, a first pressing surface 112 is formed on the holder main body 110. The first pressing surface is a surface that presses one side surface of the balustrade panel 12 while the panel holder 100 holds the balustrade panel 12. Further, the holder main body 110 is provided with a guide portion 113. The guide portion 113 extends in a direction inclined with respect to the first pressing surface 112. In this way, the holder main body 110 is formed with a gap between the first pressing surface 112 and the guide portion 113 into which the lower portion of the balustrade panel 12 is inserted.

In the configuration example described here, as shown in FIG. 8, the holder main body 110 exhibits a substantially U-shape with the upper side open when viewed from the side. Therefore, the holder main body 110 is formed with the first pressing surface 112 divided into two parts. In addition, the number of guide units 113 is also two. These two guide portions 113 are arranged in parallel with each other. The distance between the two guides 113 is d.

Next, the configuration of the pressing member 120 will be described with reference to FIGS. 9 to 11. The pressing member 120 is made of a bent steel material. The pressing member 120 includes a pressing surface forming portion 122, an upper extending portion 123, and a lower extending portion 124. A second pressing surface 121 is formed on the pressing surface forming portion 122. The second pressing surface 121 is a surface that presses the other side surface of the balustrade panel 12 while the panel holder 100 holds the balustrade panel 12.

The upper side of the pressing surface forming portion 122 is bent to the side opposite to the second pressing surface 121. The portion extending on the upper side of the pressing surface forming portion 122 on the side opposite to the second pressing surface 121 is the upper extending portion 123. In other words, one end of the upper extending portion 123 is connected to the upper end of the pressing surface forming portion 122. The lower side of the pressing surface forming portion 122 is also bent to the side opposite to the second pressing surface 121. The portion extending on the lower side of the pressing surface forming portion 122 on the side opposite to the second pressing surface 121 is the lower extending portion 124. In other words, one end of the lower extending portion 124 is connected to the lower end of the pressing surface forming portion 122.

The internal angle formed by the main surface of the upper extension portion 123 (hereinafter, also simply referred to as “upper extension portion 123”) and the second pressing surface 121 of the pressing surface forming portion 122 is an acute angle. The internal angle formed by the main surface of the lower extension portion 124 (hereinafter, also simply referred to as “lower extension portion 124”) and the second pressing surface 121 of the pressing surface forming portion 122 is an obtuse angle. The sum of the internal angle between the upper extending portion 123 and the second pressing surface 121 and the internal angle formed by the lower extending portion 124 and the second pressing surface 121 is 180 degrees. That is, the upper extension portion 123 and the lower extension portion 124 are arranged in parallel.

A through hole 125 is formed in the upper extension portion 123. The number of through holes 125 formed in the upper extension portion 123 is the same as the number of guide portions 113 of the holder main body 110. That is, in the configuration example described here, the number of through holes 125 is two. As shown in FIG. 10, the distance between these two through holes 125 is e. The distance e between the through holes 125 is equal to the distance d between the guide portions 113. The size of one through hole 125 is adjusted so that one guide portion 113 can be inserted.

As shown in FIG. 11, both sides of the lower extension portion 124 are notched, and the lower extension portion 124 is narrower than the upper extension portion 123. The width f of the lower extending portion 124 is equal to or less than the distance d between the guide portions 113 of the holder main body 110. In other words, the width f of the lower extension portion 124 is equal to or less than the distance e between the through holes 125 of the upper extension portion 123. In the illustrated configuration example, the width f of the lower extending portion 124 is equal to the distance d between the guide portions 113, that is, the distance e between the through holes 125.

Bolt insertion holes 126 are formed in each of the upper extension portion 123 and the lower extension portion 124. Further, as shown in FIGS. 6 to 8, a bolt fixing hole 114 is formed in the holder main body 110. Then, as shown in FIGS. 3 and 5, the holding member 120 is attached to the holder main body 110 by the bolt 130 passed through the bolt fixing hole 114 of the holder main body 110 and the bolt insertion hole 126 of the holding member 120. Be done. The inner diameter of the bolt insertion hole 126 is larger than the outer diameter of the threaded portion of the bolt 130. In the illustrated example, a washer is passed through the tip of the bolt 130 on the side of the bolt insertion hole 126 of the upper extension portion 123 and then fastened with a nut 131. The bolt 130 may be welded to the holder body 110. In the present disclosure, tightening with the bolt 130 and the nut 131 may be simply referred to as "tightening the bolt 130".

In the state where the panel holder 100 is assembled by the holder main body 110, the holding member 120, and the bolt 130 as described above (hereinafter, also referred to as “assembled state”), the upper extending portion 123 forms a pressing surface. It is arranged so as to extend from the upper end of the portion 122 toward the guide portion 113. Similarly, the lower extending portion 124 is arranged so as to extend from the lower end of the pressing surface forming portion 122 toward the guide portion 113.

In the assembled state, each guide portion 113 is passed through each through hole 125. The bolt 130 is arranged parallel to the extending direction of the guide portion 113. The upper extension portion 123 is arranged orthogonal to the bolt 130. That is, the upper extending portion 123 is orthogonal to the extending direction of the guide portion 113. Then, in the assembled state, the first pressing surface 112 of the holder main body 110 and the second pressing surface 121 of the pressing member 120 face each other.

When the bolt 130 is tightened in the panel holder 100 configured as described above, the holding member 120 moves with respect to the holder main body 110 due to the screw feeding action of the bolt 130. At this time, the pressing member 120 moves while being guided by the guide portion 113. As described above, the guide portion 113 extends in a direction inclined with respect to the first pressing surface 112. Further, the moving direction of the pressing member 120 is regulated in a direction parallel to the guide portion 113 by the guide portion 113 passed through the through hole 125. Therefore, when the bolt 130 is tightened, the distance between the first pressing surface 112 and the second pressing surface 121 is narrowed.

In the illustrated configuration, the through hole 125 is formed only in the upper extension portion 123, and the lower extension portion 124 does not have the through hole 125. In the assembled state, the lower extension portion 124 is arranged between the guide portions 113. Therefore, although the movement direction of the pressing member 120 as a whole is regulated by the guide portion 113, the lower extending portion 124 with respect to the guide portion 113, for example, due to elastic deformation of the steel material of the holder body 110 and the pressing member 120. It can also be displaced in a direction not parallel to the guide portion 113.

When the bolt 130 is tightened with the lower portion of the balustrade panel 12, which is the object to be fixed, arranged between the first pressing surface 112 and the second pressing surface 121, the pressing member 120 is attached to the guide portion 113 of the holder main body 110. It moves downward along the line, and at the same time, the distance between the first pressing surface 112 and the second pressing surface 121 is narrowed, and the lower portion of the balustrade panel 12 is gripped by the holder main body 110 and the pressing member 120. At this time, a part of the axial force of the bolt 130 is transmitted in the direction of gripping the balustrade panel 12, and the reaction force of this gripping force can be received by the guide portion 113, so that a reliable gripping force can be exhibited. Is.

According to the configuration of the balustrade device 10 configured as described above, a general steel material, which is superior in availability and cost as compared with aluminum, is used as the material, and no special mold and skill are required. The panel holder 100 can be manufactured by general sheet metal processing such as cutting and bending, and assembly with fastening parts. Then, a high gripping force can be exhibited with a simple structure in which a general steel material can be used as the material of the panel holder 100, and the balustrade panel 12 can be appropriately held. Therefore, the manufacturing difficulty of the balustrade device 10 can be kept low, and a wide and stable supply of parts can be achieved.

In the panel holder 100 of this embodiment, as described above, the angle formed by the upper extending portion 123 and the second pressing surface 121 is bent so as to be an acute angle. This bending angle is adjusted so that the internal angle formed by the upper extending portion 123 and the second pressing surface 121 is smaller than the inclination angle of the guide portion 113 with respect to the second pressing surface 121. Therefore, as shown in FIG. 12, the distance g between the first pressing surface 112 on the side closer to the upper extending portion 123 and the second pressing surface 121 is the first pressing on the side closer to the lower extending portion 124. The distance h between the surface 112 and the second pressing surface 121 is smaller. That is, the distance between the first pressing surface 112 and the second pressing surface 121 is shorter on the side closer to the upper extension portion 123 and longer on the side closer to the lower extension portion 124.

Therefore, when the bolt 130 is gradually tightened, the side of the second pressing surface 121 near the upper extension portion 123 starts pressing the balustrade panel 12 before the side closer to the lower extension portion 124. Further, as the bolt 130 is tightened, the holder body 110 and the pressing member 120 are elastically deformed, and the balustrade panel 12 is pressed by the entire second pressing surface 121. In this state, the force applied to the second pressing surface 121 is supported by the guide portion 113 via the upper extension portion 123. On the other hand, as described above, since the lower extension portion 124 is simply arranged between the guide portions 113, the force applied to the second pressing surface 121 is the guide portion on the lower extension portion 124 side. Not supported by 113. That is, a stronger gripping force is exerted on the side closer to the upper extension portion 123 than on the side closer to the lower extension portion 124. Therefore, the strongest gripping force can be exerted at a position near the upper end where the balustrade panel 12 is pressed by the second pressing surface 121.

Here, as a comparative example, consider a structure in which the gripping force is evenly generated on the second pressing surface 121. In this comparative example, it can easily occur that the lower side of the second pressing surface 121 has a stronger gripping force than the upper side due to a manufacturing error or the like. In such a case, the balustrade panel 12 is gripped only on the lower side of the second pressing surface 121, and a gap is formed between the second pressing surface 121 and the balustrade panel 12 on the upper side of the second pressing surface 121. Can be considered. The gap between the second pressing surface 121 and the balustrade panel 12 on the upper side causes wobbling of the balustrade panel 12.

On the other hand, according to the panel holder 100 of this embodiment, the balustrade panel 12 is pressed by a wider area of the second pressing surface 121 by utilizing the elastic deformation of the steel material constituting the holder main body 110. , The strongest gripping force can be exerted at a position close to the upper end pressed by the second pressing surface 121. Therefore, on the upper side of the second pressing surface 121, it is possible to appropriately and surely grip the balustrade panel 12 by suppressing the formation of a gap between the second pressing surface 121 and the balustrade panel 12, and the balustrade panel 12 may wobble. It can be suppressed.

The present invention can be used for a passenger conveyor balustrade device provided with a panel holder for holding the balustrade panel of the passenger conveyor.
