Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a passenger conveyor such as an escalator or an electric road, and more particularly to a parapet structure with a simplified structure.

[Conventional technology]

Passenger conveyors have been widely used as essential transportation equipment within buildings, but
Recently, there are various needs regarding this equipment, such as energy saving, safety, and lightness of design.

As shown in FIG. 1, the conventional passenger conveyor is composed of a rotating body consisting of steps 1 and handrails 2 arranged in an endless manner and rotating, and stationary bodies such as a handrail 3 and a main body frame 4. All these parts are supported by the building floor F.

The details of the balustrade 3 include the glass panel 5 supported by the main body frame 4, the inner deck 6, the outer deck 7, and the lower balustrade sap material such as the skirt guard 8, as shown in FIGS. 1 to 3. Further, on the upper side of the glass panel 5, a guide 9 for guiding the handrail, a handrail frame 10, a lighting fixture 11, and other parapet top sap members are arranged. Inside the handrail frame (generally made of stainless steel) 10, there is a gasket 12 that protects the glass panel 5.
A support 15 that holds this glass panel and supports the lamp 13 and cover 14 that constitute the lighting fixture 11, and a pusher that is fastened to this support 15 with bolts 16 to finally fix the glass panel 5. A plate 17 is provided.

Here, the dimensional relationship of the sap material on the balustrade will be explained. The guide 9 on the upper side has a size to engage with the inner circumference of the handrail 2 made of the decorative rubber part 2a and the cotton canvas part 2b, and is fixed to the handrail frame 10 with bolts (not shown). Next, the handrail frame 10 has a height h that is 2 to 3 times the size ratio to the height ha of the handrail 2, and in the lateral direction extends outward from the side edge of the handrail 2. _a , l _b to the inside (generally both l _a and l _b are 10~
It is normal for it to protrude (50 mm),
The l _a side is used for storing the lighting equipment 11, and the l _b side is used for holding the glass panel 5.

In such a conventional balustrade configuration, there has recently been an increasing need for a light design that excludes the lighting fixture 11 and that is energy-saving oriented.

Generally, when excluding the lighting fixture 11 shown in FIG. 10 etc.) is usually not modified. In a passenger conveyor that does not use such lighting equipment 11, the illuminance of the ceiling lights X and Y is increased to provide services to passengers (particularly, the footwells are sufficiently bright for safe use). The dimensional structure of the band rail frame 10 is extremely inconvenient in terms of lighting.

That is, when the brightness of the ceiling light X is guided to the step 1 side through the glass panel 5 _as shown by the arrow M as shown _in FIG. will be regulated. This situation is particularly serious when the passenger conveyor is covered with a screen S or the like, and sometimes the illuminance essential for safe use by passengers cannot be ensured.

On the other hand, conventional passenger conveyors have issues that need to be resolved in terms of safety and design.

In terms of safety, it is assumed that young children may not be able to grasp the handrail 2 reliably. In other words, as shown in Figure 3, the height H of the railing from step 1 is set to 650 to 750 mm from the perspective of preventing passengers from falling, and is a suitable height for passengers of school age and older. ing. However, in the case of young children, in addition to the height H problem, a part of the hand Q may come into contact with the corner of the handrail frame 10 (point P) as shown in FIG. 3, making it difficult to grasp the handrail 2. Become.

If the user tries to grab the handrail 2 in such an unreasonable condition, his or her feet will approach the skirt guard 8 and be pulled in around the step 1, which is extremely dangerous, as this may lead to an accident.

Furthermore, in terms of design, there is a problem in that wear powder R of the handrail 2 accumulates on the upper surface of the handrail frame 10. This abrasion powder R is a mixture of iron and rubber materials used in the drive system of the handrail 2, and the cotton canvas part 2b.As a public facility, this abrasion powder R causes a sense of uncleanness and stains passengers' clothes. Can't be ignored.

Here, a conventionally known example is the US patent
There is also No. 3989133, but it is largely the same as the conventional parapet configuration illustrated in the main text, and there is room for improvement.

As explained above, it can be seen that the conventional configuration of the balustrade 3 requires improvement in terms of energy saving, safety, and design.

For this reason, a parapet configuration as shown in Figure 4 and below has been proposed.
We are releasing products that efficiently let in sunlight while significantly improving safety and aesthetics.

Hereinafter, the structure of a recent passenger conveyor in which the above-mentioned improvements have been made will be explained.

In FIGS. 4 and 5, the drive mechanism of the rotating step 1, the structure of the main body frame 4, and the lower parapet sap material such as the inner deck 6, outer deck 7, and skirt guard 8 are the same as before, but In this configuration, a guide frame 19 (generally made of extruded aluminum) that grips the upper end of the glass panel 18 (corresponding to the conventional glass panel 5) and guides the handrail 2, and a The guide 20 provided constitutes the upper side of the parapet.

Here, the upper side of this parapet is the guide frame 19
are continuously provided over the entire length of the balustrade, and the groove 19a is fitted into the upper end of the glass panel 18 via a gasket 21 provided to cover the upper end of the glass panel 18. Then, the screw 2 set in advance on this guide frame 19
2 and the nut 23 engage with a notch (width J ₁ , depth J ₂ ) 18a provided in the glass panel 18 and a notch 21a in the gasket 21, and the screw 22
It is a mechanism that is fixed by tightening. On the other hand, the guides 20 on both sides engage with the inner periphery of the handrail 2, and one end thereof is fitted into the groove 19b of the guide frame 19, and the other end is fitted into the glass panel 1.
It has a shape that covers the open end between the handrail 8 and the handrail 2, and is made of a plastic material such as nylon that has a low coefficient of friction.

Furthermore, the upper side members of the guide frame 19 and the guide 20 are efficiently stored in the inner peripheral space of the handrail 2 in both horizontal and vertical dimensions, and are fixed to the most important glass panel 18 through the groove 19a and the notch. This can be done reliably by the fastening force of the screw 22 using the screw 18a. Note that the guide 20 is screw 2.
After fastening of 2, fitting into the groove 19b and guide frame 1
It is fixed without falling off by contact with the lower end of the handrail 9, and this structure is arranged continuously in the section where the handrail 2 runs.

As mentioned above, the recent balustrade configurations have been well received in terms of lighting (energy saving), safety, and aesthetics.

[Problem that the invention seeks to solve]

However, in the balustrade configurations shown in FIGS. 4 and 5, an unexpected external force acts as a force M _a that separates the glass panel 18 and the guide frame 19 at the upper side of the balustrade, and screws are used to resist this external force. It has become necessary to use 22 frequently. This force M _a
Although this is caused by the discomfort of passengers, increasing the number of screws 22 increases assembly costs and increases the amount of maintenance and inspection work.

2 Furthermore, an external force similar to this acts on the screw 11 portion as force M _b when the handrail 2 is reversed, as shown in FIG. This force M _b is greatest when the handrail 2 is rotated in the direction of arrow N (downstairs operation), and it is necessary to increase the amount of screws 22 as described above.

3. Furthermore, in the configuration as shown in FIG. 5, there is a concern that the notch 18a of the glass panel 18 and the metal screw 22 are likely to come into contact with each other, leading to damage to the glass panel 18.

The purpose of the present invention is to provide good lighting to the steps;
To provide a handrail for a passenger conveyor that is excellent in safety and design, does not cause damage to the glass panel, and can stably fix the glass panel and the guide frame.

[Means for solving problems]

The above object is to configure the guide frame with a plurality of guide frames arranged in the longitudinal direction of the handrail, and to bond the outer peripheral edge of the glass panel into the grooves of the plurality of guide frames with a bonding agent.
This is achieved by connecting adjacent ends of the plurality of guide frames with a joint plate, and by fixing the terminal ends of the guide frames to the main body frame.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 7 to 10.

The configurations of the handrail 2 and the guide 20 are exactly the same as those of the conventional one, so they are given the same reference numerals, but the glass panel 24 and guide frame 25 according to the present invention
are each divided into a plurality of parts in the longitudinal direction of the handrail, and each glass panel 24 and guide frame 25 are fixed with a bonding agent 26. Here, the guide frame 25 is provided with a groove 25a and a groove 25b for mounting the guide 20 in substantially the same way as the conventional guide frame 19, but this glass panel 24
The main difference is that there is no cutout 18a in the upper end of the conventional method.

On the other hand, the bonding agent 26 is a silicone-based or urethane-based adhesive, and is filled almost evenly between the groove 25a and the glass panel 24.
Note that this filling operation involves filling the groove 25a with the bonding agent 2.
A suitable amount of glass panel 6 is placed therein, and the upper end of the glass panel 24, which has been well degreased, is gradually inserted while positioning the glass panel 24, and is finally fixed in the state shown in FIG.

Next, the longitudinal direction and joint structure of the glass panel 24 and the guide frame 25 will be explained. Regarding the relationship in the longitudinal direction, as shown in FIG. 8 for a typical example of the middle part of the passenger conveyor, the guide frame 25 has a dimension of about 3 to 10 mm at both ends relative to the length L of the glass panel 24. The bonding agent 26 is filled in a short shape with a difference in height of L _a .

The glass panels 24 and guide frames 25 that are joined together as shown in Fig. 8 are arranged as a pair in the longitudinal direction of the passenger conveyor, and the joints are as shown in Fig. 9. It is designed to be combined. That is, the glass panel 24
The guide frames 25 are arranged with a gap δ (2 to 3 mm) between them, and at this time, there is a gap between the guide frames 25.
The joint configuration is such that L _b (twice as large as L _a in Fig. 8) exists. In this part, in the present invention, a joint plate 27 is used to connect the guide frames 25 to each other.
is applied from the side, and this and the guide frame 25 are connected with screws 28. This screw 28 is screwed in from the side of the guide frame 25 to integrally connect the plurality of guide frames 25. In addition, since this gap L _b has the risk of giving a sense of discontinuity in the running of the handrail 2, the guide 20
The joint has been moved to _the joint _Lc , avoiding this gap Lb.

The reason for providing the level difference L _a in FIG. 8 is to assemble and adjust the gap δ in the state shown in FIG. This is to prevent interference between the two.

On the other hand, in the present invention, special measures have been taken for the lower side of the parapet.

As shown in FIG. 10, at the end of the balustrade where the greatest detachment force acts on the glass panel 24 and the guide frame 25 fixed by the bonding agent 20, the guide frame 2
Fix the end of 5 to a part of the main body frame 4 with screw 29,
It has a structure that can sufficiently withstand the force shown by arrow M _b .

With the above configuration, the guide frame 25 is housed inside the handrail 2 to improve lighting to the steps, and in the balustrade configuration that improves safety and design, 1. Conventional notch 18a By completely eliminating the screws 22, assembly and maintenance work becomes extremely simple.

2 The glass panel 24 considered to be a damaged item is bonded with bonding agent 2.
There is an advantage that the bonding agent 26 is protected by the bonding agent 26, and vibrations caused by the running of the handrail 2 are also damped by the bonding agent 26. This also has the effect of buffering the impact force from passengers.

3. The guide frame 25 is joined to the glass panel 24 over almost the entire length of the outer periphery, and adjacent guide frames are joined by the joint plate 27, and the end of the guide frame is fixed to the main body frame 4, so that the glass panel 24 The guide frame 25 is stably fixed to the panel 24 and can sufficiently resist external force or reaction force.

In addition, although one example was explained in the main text,
The configuration is not limited to this, and a configuration as shown in FIG. 11 may be used. That is, a single guide frame 101 (conventionally, a guide 20 is used together) may be fixed to the upper end of the glass panel 100 using a bonding agent 102, and the guide frame 101 itself also has a shape that protrudes below the handrail 2. (Part Y) may also be used. In addition, although one guide frame 25 is bonded to the glass panel 24 in FIG. 8, one guide frame 25 may be bonded to two glass panels 24 if it is permitted for handling and transportation of this part. There is no problem either.

〔Effect of the invention〕

According to the present invention described above, it is possible to provide a railing structure for a passenger conveyor that is bright and light, has a high design quality and stability, and can securely fix the guide frame and the glass panel without damaging the glass panel. There are advantages.
