Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handrail for a passenger conveyor such as an escalator or an electric road, and more particularly to a handrail structure suitable for enhancing the design effect of a handrail member made of stainless steel plate.

Passenger conveyors have become widely established as indispensable service equipment in buildings, but in recent years, a wide variety of demands have been made, especially in terms of the design of handrails.

As is well known, the handrail makes up the majority of the design of a passenger conveyor, and everyone involved recognizes that its design is extremely important as it determines the quality of interior decoration.

Generally, as shown in FIGS. 1 and 2, the railing of a passenger conveyor includes a step 1 and a handrail 2, which are arranged in an endless manner and rotate to carry passengers, as well as a handrail 2 that moves the step 1. A supporting rail 3, a handrail deck 4 that guides the handrail 2, a parapet panel 5, a substantially U-shaped decorative packing 6, an inner support 7, and an outer deck 8.
It is composed of a stationary body such as an exterior plate 9 and the like.

The parapet panel 5 and the inner deck 7 are fixed to a sturdy main body frame 13 by several supports 10, and the outer deck 8 is fixed to several supports 11 by welding or bolts 12, etc. .

Here, the handrail deck 4, inner deck 7, and outer deck 8 are called design members, and the quality of the overall design is determined by the finished state of these members.

It is well known that beautiful decorative materials made from extruded aluminum alloy or molded materials treated with alumite have been widely used as materials for these decorative parts, but recently, materials such as the one shown in Figure 2 have been widely used. Thin stainless steel sheets are also beginning to be used.

Balustrades made of stainless steel plates are popular for their unique surface luster, and have other advantages such as being hard, resistant to scratches and dents, and having excellent corrosion resistance. For this reason, its widespread use is desired.

In particular, the completely transparent type shown in the figure (a model that uses transparent glass for the balustrade panel 5) perfectly combines the metallic luster characteristic of stainless steel plates with the transparency of glass plates, and is now positioned as the highest quality balustrade. There is.

However, among the balustrade members made of stainless steel plates, the structure of the inner deck 7 and outer deck 8 in particular has the following drawbacks, and a solution to these problems is desired.

In other words, stainless steel plates are 3 to 5 times more expensive than ordinary steel materials, so if you want to produce a low-cost passenger conveyor, you will inevitably use ultra-thin stainless steel plates. It is difficult to plastically process the material, and it is extremely difficult to maintain a beautiful surface condition for a long time.

In particular, like a passenger conveyor, there is a concave curved section (not shown) and a convex curved section U from the lower entrance (not shown) to the upper entrance.
1 and U2, as well as those that draw unique streamlines such as the terminal curved part T, are difficult to bend, and especially in the case of thin materials, local deformation such as distortion is likely to occur due to slight external force or heat. That will be easily understood.

Here, among the parapet members, to explain the design defects using the outer deck 8 as a representative example, the outer deck 8 is fixed to the support 11 with screws 14 as shown in FIG. In this case, the stainless steel plate was used, but the surface gloss was destroyed by screws 14, resulting in unpopularity.

As is clear from FIG. 3, the screws 14 scattered above the support 11 detract from the design sense that emphasizes its beautiful flat surface.

Furthermore, if the screw 14 is strongly tightened, it also includes the problem that strain A is generated around the screw 14.

This problem is caused by the fact that the outer deck 8 is almost planar and reflects the light source of the parapet lighting or the ceiling of the building as shown by the arrow Z, which further accentuates the distortion A, resulting in the worst situation.

On the other hand, when the back surface of the long outer deck 8 is bonded to the support 11 having the slightly long upper surface 11a using adhesive S or the like as shown in FIG. Strain B occurs.

This is especially true when the outer deck 8 is fixed to the main body frame 13 at a curved portion (such as the U2 section in FIG. 1).
This often occurs when bows are forcibly stretched while ignoring differences in curvature caused by manufacturing errors or twisting of the material, and can be said to be a unique weakness of thin plate materials.

Moreover, if it is forcibly drawn toward the main body frame 13 side in this way, the adhesive S will peel off and the outer deck 8 will spring upward (in the direction of the arrow Y), resulting in a problem.

Here, as shown in FIG. 5, when a welding bolt 15 is joined to the back surface of the outer deck 8 and this welding bolt 15 is used to fix it to the support body 11 with a nut 16, the above-mentioned adhesive method is used. I have a similar problem.

In other words, the welded bolt 15 is welded using a heat welding method generally referred to as stud welding, but the welding heat deforms the outer deck 8 and strain C occurs due to the downward tensile force (in the direction of the arrow Q). Resulting in.

Furthermore, as shown in FIG.
A similar problem occurs when 1 is directly welded.

That is, the welding heat of the weld bead 17 causes a large thermal strain D.
This is a fatal flaw that makes it impractical for practical use.

As mentioned above, placing the screws 14 on the surface of the balustrade member that should be the most beautiful, or providing fixing parts locally on the back side of the long material by gluing, welding, etc., is not optimal with any of the conventional methods. However, it is clear that the design of the passenger conveyor has been significantly degraded.

As described above, the drawbacks of the conventional method are firstly that the fixing portion is locally provided on the surface of the parapet member such as the outer deck 8 or immediately behind it, that is, on the most visible part.

In order to avoid the above-mentioned distortions A, B, C, and D, it is necessary to use expensive plates with a thickness of about 5 mm, which results in the worst situation of causing inconvenience to the user. This is what I was looking for.

In view of this point, the present invention has been made in order to provide a balustrade structure in which the above-mentioned distortion does not occur on the surface of the balustrade member.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings, taking an outer deck as an example.

In Figures 7 and 8, handrail deck 4,
The basic structure of the parapet members such as the inner deck 7, as well as the step 1 and the handrail 2, are completely the same as conventional ones, so illustration can be omitted, but in the present invention, the outer deck 1
8 (a member corresponding to the conventional outer deck 8), a long support along the longitudinal direction of this outer deck 18 is attached to the back side of the end 18a on the side of the parapet panel 5 and the end 18b on the side of the exterior board 9. Piece 1
The feature is that 9 is arranged.

In this case, the support piece 19 is firmly bonded to the back surface of the outer deck 18 with an adhesive S, and a support body 20 is fixedly bonded below this support piece 19.

The most suitable adhesive S is Cemedine or a resin-based adhesive, which has recently become more reliable, and it is preferable that the support piece 19 and the support body 20 be welded together.

And to the support piece 19 integrated with the outer deck 18;
The supports 20 are fixedly installed at appropriate intervals, and are ultimately fixed to the main body frame 13 using bolts 12 or the like using the holes 20a at the bottom of the supports 20, as in the conventional case. It is.

By doing this, the outer deck 18 is evenly supported in its longitudinal direction by the supporting pieces 19, and is free from strain A, B due to the screws 14 or welding heat as in the conventional case.
It has the advantage that harmful defects such as C and D do not occur.

The reason why this advantage was achieved is, of course, that the conventional welding method is not used, but the long support piece 19 is arranged along the longitudinal force direction of the outer deck 18. By doing so, it is possible to eliminate the local deformation as explained in FIG. 4 in the prior art.

According to the present invention described above, there is an advantage that a railing for a passenger conveyor with excellent design can be provided.

In addition, although the above explanation took the outer deck as an example, the present invention is applicable not only to the outer deck but also to all parapet members such as the inner deck and the handrail deck.

Moreover, various application examples of the present invention can be considered based on the embodiment shown in FIG.

That is, as shown in FIG. 9, a support piece 21 made of channel steel may be provided on the back surface of the outer pole 1B, and the fixing bolt 22 may be attached to the groove 21a of this support piece 21.

In this case as well, the support piece 21 and the outer deck 18 are joined with adhesive, but there is an advantage that the fixing bolts 22 can be easily attached and the assembly work of the passenger conveyor can be speeded up.

In short, the present invention provides, on the back side of a parapet member such as an outer deck,
Any parapet member in which a long support piece is provided along the longitudinal direction of the parapet member falls within the scope of the present invention.
