Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a passenger conveyor such as an escalator or an electric road, and more particularly to a handrail structure with a simplified structure.

Passenger conveyors have been widely used and widely used as essential transportation equipment within buildings, but recently there have been a wide variety of needs regarding this equipment, such as energy saving, safety, and lightness of design.

As shown in FIG. 1, the conventional passenger conveyor consists of a rotating body consisting of steps 1 and band rails 2 which are arranged in an endless manner and rotate, 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 parapet 3 are as shown in Figures 1 and 2.
A glass panel 5 supported by the main body frame 4, an inner deck 6,
The lower sap material of the parapet, such as the outer deck 7 and the skirt guard 8,
Further, on the upper side of the glass panel 5, there is a guide 9 for guiding the band rail, a band rail frame 10, and a lighting fixture 11.
Sapwood is placed above the parapet.

Inside the band rail frame (generally made of stainless steel) 10, there is a gasket 12 that protects the glass panel 5, and a gasket 12 that holds the glass panel and that holds the lighting fixture 1.
A support body 15 that supports the lamp 13 and the cover 14 constituting the glass panel 1 is further provided, and a push plate 17 is further provided to this support body 15 to be fastened with a port 16 to finally fix the glass panel 5.

Here, the dimensional relationship of the sap material on the balustrade will be explained.

The guide 9 on the upper side is the decorative rubber part 2a and the cotton canvas part 2.
It is dimensioned to engage with the inner periphery of the band rail 2 consisting of b, and is attached to the band rail frame 1 by bolts (not shown)
Fixed to 0.

Next, the band rail frame 10 has a height h that is 2 to 3 times the size ratio to the height ha of the band rail 2, and the yellow direction is from the side edge of the band rail 2 to the outside. l
A, la (generally 10 to 50 mm for both la and lb) protrudes inward, and the la side is used to store the lighting equipment 11, and the lb side is used to hold 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 equipment 11 and that is energy-saving oriented.

Generally, when excluding the lighting fixture 11 shown in FIG. ) It is normal not to make any changes at all.

In a passenger conveyor that does not use such lighting equipment 11,
The illuminance of the ceiling lights X and Y will be increased to provide a service to passengers (particularly to ensure that the footwells are sufficiently bright for safe use), but the conventional dimensional configuration of the band rail frame 10 is extremely inconvenient in terms of lighting. be.

In other words, when the brightness of the ceiling light X is guided to the step 1 side through the glass panel 5 as shown in FIG. 1, the protruding dimension la and height h of the hanger rail frame 10 will regulate the incident angle θ1 of the light beam. .

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, there are also problems that need to be solved in terms of efficiency, safety, and design in conventional passenger conveyors.

In terms of safety, it is conceivable that a young child may not be able to grasp the band rail 2 reliably.

In other words, as shown in Figure 2, the height of the handrail from step 1 is 650~7 from the viewpoint of preventing passengers from falling.
The height is set at 50 mm, making it a suitable height for passengers of school age or above.

However, in the case of young children, in addition to the height H problem, the negative part of the hand Q comes into contact with the corner of the band rail frame 10 (point P) as shown in FIG. 2, making it difficult to grasp the band rail 2. .

If an attempt is made to grasp the band rail 2 in such an unreasonable condition, it is extremely dangerous because the feet may approach the skirt guard 8 and be pulled in around the step 1, causing an accident.

Furthermore, in the design part, there is a problem that abrasion powder R of the band rail 2 accumulates on the upper surface of the band rail frame 10.

This abrasion powder R is a mixture of the iron and rubber materials used in the drive system of the band rail 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.

Therefore, the present inventors recently proposed a parapet configuration shown in FIG. 3.

This structure increases the height h of the conventional band rail frame 10.
The guide frame 19 shown in FIG. 3 has two functions: guiding the band rail 2 and maintaining the strength of the glass panel 18.

Therefore, the portion shown by the imaginary line in FIG. 3 completely disappears, resulting in a form that greatly improves ease of use, safety, and aesthetics, which were considered drawbacks in the past.

As shown in FIG. 3 and an exploded view of the guide frame 19 in FIG. The groove 19a is fitted into the upper end of the glass panel 18 via the groove 19a.

The screws 22 and nuts 22 provided for fastening the groove 193 of the guide frame 19 are connected to the notches (width J7, depth J7) provided at the upper end of the glass panel 18.
2) and the notch 21a of the gasket 21 to finally tighten the glass panel 18 from both sides.

On the other hand, the guides 20 on both sides engage with the inner periphery of the band rail 2, and one end thereof is fitted into the groove 19b of the guide frame 19, and the other end is inserted into the open end between the glass panel 18 and the band rail 2. It has an overlapping shape and is made of a plastic material such as nylon that has a low coefficient of friction.

In the above-described balustrade configurations shown in FIGS. 3 and 4, the fastening force between the guide frame 19 and the glass panel 18 is the most important point in guiding the band rail 2 and maintaining the strength of the balustrade, and there are measures to increase the fastening force. has become a proposition.

The configuration shown in FIG. 4 has the following problems to be solved.

That is, in the configuration shown in FIG. 4, it is assumed that the screws 22 are fastened with the interval P2 of the notches 21a exactly matching the interval P1 of the notches 18a.

This premise is based on the following premise: Since structures such as the guide frame 19 are downsized, the critical screw 22 has to have a small diameter, and its fastening force acts only on a small area very close to the hole 18a. Therefore, the positional relationship of the gasket 21, which has the function of directly transmitting the fastening force via the guide frame 19 to the glass panel 18, with respect to the notch 18a is extremely important.

However, in the configuration shown in FIG. 4, a problem as shown in FIG. 5 may occur.

In other words, it deviates by a distance a from the end of the notch 18a (due to accumulation of manufacturing errors and assembly errors), resulting in a range beyond the tightening force of the screw 22 by this amount a.

Since the tightening force of the screws 22 depends on the size of the contact area between the glass panel 18 and the gasket 21 in the vicinity of the notch 18a, the above-mentioned deviation (distance a) is extremely important.

In view of this point, the present invention has been made to ensure the correct positional relationship between the glass panel 18 and the gasket 21.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIG. 6, a glass panel 1 having a notch 18a is shown.
8 is the same as the conventional one, but in the present invention, the notch 18 is
It is characterized by the fact that the gaskets are placed on both sides of the cut a.

A plurality of gaskets 24, 25, 26, and 27 are arranged, of which gaskets 25 and 26 will be explained as representative examples.

A packing 25 is arranged on the right side of the notch 18a, and a packing 26 is arranged opposite to this, and the lengths 11 and 12 of each are smaller than the interval P1, and CP, -J,
) has smaller dimensions.

There is a gap 13 between the gaskets 25 and 26'.

For this reason, the gaskets 25 and 26 each have a notch 18.
It can be installed according to the end 18b of
) can be adjusted by adjusting the distance 13.

This adjustment is the same for the gaskets 24 and 27 as well.

By doing this, the positional relationship between the glass panel 18 and the plurality of gaskets 26 etc. is ensured correctly, and the screws 22
There is an advantage that the fastening can be performed reliably.

According to the present invention described above, there is an advantage that the fastening strength of the guide frame 19 that guides the band rail 2 is increased, and a predetermined balustrade strength can be ensured.

Therefore, even with a parapet configuration in which the guide frame 19 is downsized and housed within the inner periphery of the band rail 2, the strength problem can be solved.
