1-2. Structure of falling object preventing guardrail

Next, a structural example of the falling object prevention guard rail 15 of the present example will be described with reference to fig. 2 to 6.

Fig. 2 is a perspective view showing the falling object prevention fence 15.

As shown in fig. 1 and 2, a falling object prevention guard (hereinafter, simply referred to as a "guard") 15 includes a plurality of posts 16 fixed to the frame 2 and vertically provided upward in the vertical direction from the frame 2, and a plurality of panel members 17 supported by the posts 16. The panel member 17 is formed of a transparent or translucent member, for example, an acrylic panel.

Fig. 3 is an exploded perspective view showing the column 16, and fig. 4 is a plan view showing the guard rail 15. Fig. 5 is a front view showing the column base 21 fixed to the inclined section of the frame 2.

As shown in fig. 3, the column 16 includes a column base 21, a support member 22, and a coupling member 23.

Support base "

The column base 21 has a fixing portion 25 and a column portion 26. The fixing portion 25 is formed in a substantially flat plate shape. The fixing portion 25 is formed with two bolt fixing holes 25a and four adjusting bolt fixing holes 25 b. Two bolt fixing holes 25a are formed at both ends of the fixing portion 25 in the longitudinal direction.

The bolt fixing hole 25a is screwed with the fixing bolt 41. As a result, as shown in fig. 4, the column base 21 is fastened and fixed to the upper frame 2a of the frame 2 by the fixing bolt 41. In the upper and lower horizontal sections of the frame 2, the fixing portion 25 is fixed to the fixing bracket 2 b. In addition, the fixing portion 25 is fixed to the outer side of the rail portion 7 in the width direction in the vertical projection plane of the upper frame 2 a.

The four adjusting bolt fixing holes 25b are formed closer to the center of the fixing portion 25 in the longitudinal direction than the two bolt fixing holes 25 a. Four adjusting bolt fixing holes 25b are formed on one side and the other side in the longitudinal direction and one side and the other side in the short direction of the fixing portion 25. A jack bolt 45 (see fig. 5) showing a tilt adjusting member for adjusting the tilt of the column base 12, which is the direction in which the column 16 is vertically installed, is attached to the adjusting bolt fixing hole 25 b.

The support portion 26 is formed at the center of the fixing portion 25 in the longitudinal direction with respect to the four adjusting bolt fixing holes 25 b. The pillar portion 26 protrudes vertically upward from the fixing portion 25. The column 26 fixed to the column base 21 of the fixed bracket 2b is vertically provided from the fixed portion 25 substantially vertically in the upper horizontal section or the lower horizontal section of the frame 2.

Fig. 5 is a view showing the column base 21 fixed to the inclined section of the frame 2.

As shown in fig. 5, the column part 26 of the column base 21 fixed to the inclined section of the frame 2 is vertically provided at an inclination angle corresponding to the inclination angle of the inclined section of the frame 2 with respect to the fixing part 25.

Further, the direction in which the column portion 26 extends can be adjusted by adjusting the fastening amount of the jack bolt 45 that is screwed into the four adjusting bolt fixing holes 25 b. This allows the column base 21 to be fixed to the frame 2 in a state where the direction in which the column portion 26 extends is substantially parallel to the vertical direction.

The pillar portion 26 is formed with two base-side fixing holes 26 a. Two base-side fixing holes 26a are formed in one end portion and the other end portion of the pillar portion 26 in the vertical direction. The two base-side fixing holes 26a are formed in both end surfaces in a direction perpendicular to the vertical direction of the column portion 26 and also perpendicular to the width direction of the frame 2.

As shown in fig. 4, when the fixing portion 25 is fixed to the upper frame 2a, the pillar portion 26 penetrates the through hole 9b formed in the upper surface portion 9a of the outer lid 9. The upper surface portion 9a is provided with a decorative plate 9c for blocking a gap between the pillar portion 26 and the through hole 9 b.

Support member "

Next, the support member 22 will be described.

The support member 22 has a 1 st support member 27 and a 2 nd support member 28. The 1 st support member 27 is formed in a substantially flat plate shape. The 1 st support member 27 has an insertion hole 31 formed at one end in the longitudinal direction, i.e., at a lower portion in the vertical direction. The insertion hole 31 is formed in the center of the 1 st support member 27 in the lateral direction. The insertion hole 31 is an opening portion that opens in a rectangular shape.

The 1 st support member 27 has a fixing hole 27a formed in the other end portion in the longitudinal direction, i.e., in the upper portion in the vertical direction. The fixing hole 27a is formed in a substantially central portion in the short side direction of the 1 st supporting member 27.

The 2 nd support member 28 is formed in a substantially flat plate shape. The 2 nd supporting member 28 is composed of a main surface portion 32, a protruding portion 33, and a supporting-side connecting portion 34. The protruding portion 33 is formed on the surface of the main surface portion 32 facing the 1 st supporting member 27. The ridge 33 is formed in the center of the main surface 32 in the short direction. The protrusions 33 extend from the upper end of the main surface portion 32 in the vertical direction toward the lower end by a predetermined length. The protruding strip 33 has a support-side coupling portion 34 formed at a lower end portion in the vertical direction.

The supporting-side connecting portion 34 is formed continuously from the front end portion of the protruding strip 33 in the protruding direction toward the 1 st supporting member 27. The support-side coupling portion 34 is formed with two support-side fixing holes 34 a. Two support-side fixing holes 34a are formed in the upper end portion and the lower end portion of the support-side coupling portion 34 in the vertical direction. The two support-side fixing holes 34a are formed in both end surfaces in a direction orthogonal to the vertical direction of the support-side coupling portion 34 and also orthogonal to the direction in which the support-side coupling portion 34 protrudes.

The supporting-side coupling portion 34 is inserted into the insertion hole 31 of the 1 st supporting member 27. Thereby, the main surface portions 32 of the 1 st support member 27 and the 2 nd support member 28 are opposed. In addition, the 1 st support member 27 and the 2 nd support member 28 are fastened and fixed by screwing the fixing screw 44 to the fixing hole 27a provided in the 1 st support member 27.

Fig. 6 is a perspective view showing the support member 22 and the panel member 17.

As shown in fig. 6, a gap P1 is formed between the main surface portions 32 of the 1 st and 2 nd support members 27, 28 by the protruding portions 33 provided to the 2 nd support member 28. The panel member 17 is inserted into the gap P1. In addition, the support member 22 supports the panel member 17 by the main surface portions 32 of the 1 st support member 27 and the 2 nd support member 28.

The support-side coupling portion 34 of the 2 nd support member 28 is disposed above the pillar portion 26 of the pillar base 21 in the vertical direction. At this time, the support-side connecting portion 34 and the pillar portion 26 are disposed further inward in the width direction of the frame 2 than the panel member 17. The column base 21 and the support member 22 are coupled by a coupling member 23.

Connecting member "

Next, the coupling member 23 will be explained.

As shown in fig. 2 and 3, the coupling member 23 is composed of two coupling plates 29, 29. The coupling plate 29 is formed of a flat plate-like member having a substantially rectangular shape. The linking plate 29 is formed with two 1 st fixing holes 29a and two 2 nd fixing holes 29 b. The 1 st fixing hole 29a is formed at a lower portion of the connection plate 29 in the vertical direction, and the 2 nd fixing hole 29b is formed at an upper portion of the connection plate 29 in the vertical direction.

The 1 st fixing hole 29a faces a base side fixing hole 26a of the pillar portion 26 provided in the pillar base 21. The 2 nd fixing hole 29b faces a supporting side fixing hole 34a provided in the supporting side connecting portion 34 of the 2 nd supporting member 28. The support column portion 26 and the support-side coupling portion 34 are sandwiched between the two coupling plates 29, 29.

The opening diameter of the base-side fixing hole 26a is set larger than the opening diameter of the 1 st fixing hole 29a, and the opening diameter of the support-side fixing hole 34a is set larger than the opening diameter of the 2 nd fixing hole 29 b.

The base-side fixing hole 26a and the 1 st fixing hole 29a are screwed together by a 1 st coupling bolt 42, and the support-side fixing hole 34a and the 2 nd fixing hole 29b are screwed together by a 2 nd coupling bolt 43. Thereby, the coupling plate 29 is fastened and fixed to the column part 26 and the support-side coupling part 34 by the 1 st coupling bolt 42 and the 2 nd coupling bolt 43. As a result, the column base 21 and the support member 22 are coupled by the two coupling plates 29.

Two base-side fixing holes 26a are provided in the column portion 26, and two support-side fixing holes 34a are provided in the support-side connecting portion 34. This prevents the connecting plate 29 and the support-side connecting portion 34 from rotating about the 1 st connecting bolt 42 and the 2 nd connecting bolt 43.

2. Example of setting work of falling object prevention guard

Next, an installation work example of the guard rail 15 having the above-described configuration will be described with reference to fig. 7 to 9.

Fig. 7 to 9 are views showing the installation work of the guard rail 15.

First, as shown in fig. 7, the column base 21 is fixed to the upper frame 2a or the fixing bracket 2b of the frame 2 by the fixing bolt 41. In the column base 21A provided in the upper horizontal section and the lower horizontal section, the column part 26 protrudes substantially perpendicularly from the fixing part 25. In the pillar base 21B provided in the inclined section, the pillar portion 26 projects obliquely from the fixing portion 25. Further, the direction in which the column portion 26 extends, that is, the inclination of the column base 21 can be adjusted by adjusting the fastening amount of the jack bolts 45 screwed into the four adjusting bolt fixing holes 25 b. This allows the direction in which the column portion 26 extends to be parallel to the vertical direction.

The work of fixing the pillar base 21 to the frame 2 may be performed when the frame 2 is manufactured, or may be performed when the passenger conveyor 1 is installed in a building structure. In addition, the work of installing the guard rail 15 on the passenger conveyor 1 in the building structure can be performed relatively easily by fixing the pillar base 21 in advance at the time of manufacturing the frame 2. Further, the rigidity of the strut 16 can be ensured by fixing the strut mount 21 to the frame 2.

Next, as shown in fig. 8, the inner cover plate 8 and the outer cover plate 9 of the cover plate portion 4 are attached to the frame 2, and the outer cover plate 9 is covered from above in the vertical direction with respect to the pillar base 21. At this time, the pillar portion 26 of the pillar base 21 penetrates the through hole 9b provided in the upper surface portion 9a of the outer cover 9. A decorative plate 9c is provided around the through hole 9b of the upper surface portion 9 a. This allows the decorative plate 9 to block the gap between the pillar portion 26 and the through hole 9b, thereby improving the appearance of the passenger conveyor 1.

Next, the support-side coupling portion 34 of the 2 nd support member 28 is inserted into the insertion hole 31 of the 1 st support member 27, and the 1 st support member 27 and the 2 nd support member 28 are fastened and fixed by the fixing screw 44. The support-side coupling portion 34 of the support member 22, which is formed by integrally fixing the 1 st support member 27 and the 2 nd support member 28, is disposed above the pillar portion 26 of the pillar base 21 in the vertical direction. At this time, the supporting-side connecting portion 34 is disposed on the side of the balustrade portion 7 with respect to the gap P1 formed between the 1 st supporting member 27 and the 2 nd supporting member 28.

Next, the support-side coupling portion 34 and the column portion 26 are sandwiched by the two coupling plates 29. The two coupling plates 29 are temporarily fixed to the column portion 26 and the support-side coupling portion 34 by the 1 st coupling bolt 42 and the 2 nd coupling bolt 43. Thereby, the column base 21 and the support member 22 are coupled by the coupling member 23. As a result, the temporary assembly of the strut 16 is completed.

Next, as shown in fig. 6, the panel member 17 is inserted into the gap P1 formed between the 1 st support member 27 and the 2 nd support member 28. The strut 16 is divided into a strut base 21, a support member 22, and a coupling member 23, and each is fixed by a fixing screw, not by welding. This can shorten the time required for the fixing work.

As described above, the opening diameter of the base-side fixing hole 26a is set larger than the opening diameter of the 1 st fixing hole 29a, and the opening diameter of the support-side fixing hole 34a is set larger than the opening diameter of the 2 nd fixing hole 29 b.

Therefore, after the support column 16 is temporarily assembled, the positions of the support member 22, the coupling member 23, and the panel member 17 can be adjusted. Since the position of the panel member 17 can be adjusted, the panel member 17 can be arranged so as to match the curved portions formed at the boundary between the upper horizontal section and the inclined section and the boundary between the lower horizontal section and the inclined section on the cover plate portion 4.

The base-side fixing hole 26a and the support-side fixing hole 34a are shielded by the connecting plate 29. Therefore, even if the opening diameters of the base-side fixing hole 26a and the support-side fixing hole 34a are set larger than the opening diameters of the 1 st fixing hole 29a and the 2 nd fixing hole 29b, the appearance of the guard rail 15 can be prevented from being damaged.

In this example, the opening diameters of the base-side fixing hole 26a and the support-side fixing hole 34a are set to be larger than the opening diameters of the 1 st fixing hole 29a and the 2 nd fixing hole 29b, but the present invention is not limited thereto. For example, the opening diameters of the 1 st fixing hole 29a and the 2 nd fixing hole 29b on the side of the coupling member 23 may be set larger than the opening diameters of the base-side fixing hole 26a and the support-side fixing hole 34 a. In this case, the positions of the support member 22, the coupling member 23, and the panel member 17 can be adjusted even after the support column 16 is temporarily assembled.

When the adjustment work of the positions of the support member 22, the coupling member 23, and the panel member 17 is completed, the 1 st coupling bolt 42 and the 2 nd coupling bolt 43 are fastened, and the coupling plate 29 is formally fixed to the column portion 26 and the support-side coupling portion 34. Thereby, as shown in fig. 9, the installation work of the guard rail 15 is completed.

The column base 21 is fixed to the upper frame 2a or the fixing bracket 2b of the frame 2 and is disposed in the vertical projection plane of the frame 2. Then, as shown in fig. 4, the panel member 17 is disposed in a vertical projection plane of the outer cover 9 constituting the cover plate portion 4.

This prevents the guard rail 15 from protruding outward in the width direction of the passenger conveyor 1, and can narrow the gap between the guard rail 15 and the balustrade portion 7. Since the gap between the guard rail 15 and the rail portion 7 can be narrowed, it is possible to prevent a person or an object from entering between the guard rail 15 and the rail portion 7.

The coupling member 23 couples the support member 22 and the column base 21 to the inside of the panel member 17 in the width direction of the frame 2. That is, the column part 26 to which the connecting plate 29 is fixed and the support-side connecting part 34 are disposed further inward than the panel member 17 in the width direction of the frame 2. In fig. 1, 7, and 9, the column portion 7 and a part of the cover plate portion 4 are shown in a transparent manner to show the structure of the support column 16.

Therefore, the work of coupling the pillar base 21 and the support member 22 by the coupling member 23 can be performed from the inner side of the pair of balustrade portions 7, that is, the step 5. As a result, it is not necessary to provide a working space such as a footing for installing the guard rail 15 on the outer side in the width direction of the passenger conveyor 1, and it is possible to save the working space and to perform the installation work relatively easily.

Further, since the pillar portion 26 and the support-side coupling portion 34 are disposed further inward than the panel member 17, it is possible to prevent bolt-like articles or tools such as the 1 st coupling bolt 42 and the 2 nd coupling bolt 43 from falling from the outer side in the width direction of the passenger conveyor 1 during installation work.

The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the spirit of the invention described in the scope of the claims.

In the above embodiment, the escalator in which the steps have a difference in height was described as an example of the inclined passenger conveyor, but the passenger conveyor of the present invention can be applied to a moving road having a plurality of steps in which no difference in height occurs between the steps, that is, a so-called moving walkway.

In addition, the present invention is also applicable to a passenger conveyor having a frame: a frame having a portion parallel to the upper horizontal section and the lower horizontal section is provided in at least a part of the inclined section. Also, the present invention is equally applicable to a passenger conveyor having a frame comprising: the extending direction of the inclined section is changed in a curved manner, so that the extending direction of the upper horizontal section is different from that of the lower horizontal section.

In the present specification, terms such as "parallel" and "orthogonal" are used, but they do not mean "parallel" and "orthogonal" strictly, and include "parallel" and "orthogonal" and may be in a state of "approximately parallel" and "approximately orthogonal" within a range in which the functions thereof can be exhibited.
