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 handrail structure with a simplified structure.

[Background of the invention]

Passenger conveyors are used as essential transportation equipment in buildings and have become widely used, but recently there are various needs for permanent construction, such as energy saving, safety, and lightness of design.

The configuration of a conventional passenger conveyor consists of a rotary body consisting of steps 1 and handrails 2 which are arranged in an endless manner and rotate as shown in FIG. All of these parts are supported under the building floor.

The details of the parapet 3 include the glass panel 5 supported by the main body frame 4 and the inner deck 6, as shown in Figures 1 to 3.
, the lower parapet sap material such as the outer deck 7 and the skirt guard 8, and furthermore, on the upper side of the glass panel 5, a guide 9 for guiding the handrail, a handrail frame 1O1 and a lighting fixture 1 are installed.
First-class sapwood is placed above the parapet. Inside the handrail frame (generally made of stainless steel) 10, there is a gasket 12 that protects the glass panel 5, and supports a lamp 13 and a cover 14 that grip the glass panel and constitute the lighting equipment 11. A support member 15 is further provided to support the support member 15, and a push plate 17 is fastened to the support member 15 with a pin 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 sized to engage with the inner periphery of the handrail 2 consisting of the decorative rubber part 2a and the cotton canvas part 2b, and is fixed to the handrail frame 1O by bolts (not shown). Next, handrail frame 1 (1:
, has a height h that is 2 to 3 times the size ratio to the height h6 of the handrail 2, and in the lateral direction, from the side edge of the handrail 2 to the outside t, to the inside tb (generally t ,.

Usually, the protruding parts (Ah and 10 to 50 mm) are used for storing the lighting fixture 11 on the p, t and sides, and for holding the glass panel 5 on the 7b side.

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.
・Normally, the throat 1/-ru frame 10, etc.) are not modified. In passenger conveyors that do not use such lighting equipment 11, the illuminance of the ceiling lights X and Y is increased to provide services to passengers (particularly to ensure that the footwells are sufficiently bright for safe use). The dimensional configuration of the handrail frame 100 is extremely inconvenient in terms of lighting.

In other words, as shown in Figure 2, the brightness of the ceiling light X is indicated by the arrow M.
Step i side Vc4 through the glass panel 5 as shown in
<field=-, protrusion dimension t of the handrail frame 10,
and the height h regulates the incident angle θl 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, in the conventional passenger conveyor, there are problems that need to be solved in terms of completeness and design.

In terms of safety, it is assumed that there may be a situation where young children are unable to grasp the handrail 2 reliably. That is, as shown in Figure 3, the height H of the railing from step 1 is set to 650 to 750 mm from a point that prevents passengers from falling, which is a suitable height for passengers of school age and above. ing. However, in the case of young children, in addition to the problem of height H, part of the hand Q may come into contact with the corner of the hand rail frame 10 (point P) and the child may not grasp the hand rail 2. It will be in a similar state.

If an attempt is made to grasp the foot rail 2 in such an unreasonable condition, it is extremely dangerous because the feet will approach the skirt guard 8 and the rider will be pulled into the step 1 turn υ, causing an accident.

Furthermore, in terms of design, there is a problem in that the abrasion 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 Nordrail 2, and the cotton canvas part 2b.As a public facility, this abrasion powder R causes a sense of filth and stains passengers' clothes. cannot be ignored.

Here, as a conventionally known example, US Patent A 39
89133, etc., but it is largely the same as the conventional parapet configuration exemplified in the main text, and there is room for improvement.

As explained above, the conventional configuration of the balustrade 3 requires improvements in terms of energy saving, safety, and design.

[Purpose of the invention]

In order to improve the above-mentioned problems, the present invention efficiently brings light onto the step 1 in a parapet configuration that is not equipped with lighting equipment such as lamps or covers, and also improves safety based on a light design sense. This was done to provide a man conveyor that is securely fixed.

[Summary of the invention]

The present invention relates to a step that is arranged in an endless manner and rotates, a handrail that rotates synchronously with the step, and a handrail that is provided below the handrail and includes a glass panel and a parapet sap material such as a guide. At the upper end of the glass panel, a guide frame for gripping the glass panel and a parapet top sap material such as a guide for guiding the handrail are housed within the inner periphery of the handrail, and the railing is provided above the guide frame. The convex portions of the front six guides are fitted into the groove portions and the four portions provided on the lower side of the guide frame.

[Embodiments of the invention]

Hereinafter, one embodiment of the F1 invention will be described based on the drawings.

In Figures 4 and 6, the drive mechanism of the rotating step 1, the structure of the main body frame 4, and the lower parapet sap materials such as the inner deck 6, the outer deck 7, and the skirt guard 8 are the same as conventional ones. However, in the present invention, the upper end of the glass panel 18 (corresponding to the conventional glass panel 5) is grasped, and the
The feature is that the upper side of 11A is formed by a guide frame 19 (generally made of extruded aluminum) that guides the hand rail 2, and a guide 20 attached along the outer periphery of this guide frame 19.

Here, to explain the structure of this upper side of the balustrade, the guide frame 19 is continuously provided over the entire length of the balustrade, and the guide frame 19 is installed continuously over the entire length of the balustrade, and is connected to the guide frame 19 through a gasket 21 provided to cover the upper end of the flannel 18. The groove 19a is fitted into the upper end of the glass panel 18. Then, screws 22 and nuts 23 set in advance in the guide frame 19 are inserted into the groove 19a.
The part is a notch (width J1) provided in the glass panel 18.
, depth J2) 18" and the notch 21a of the packing 21, and is fixed by tightening this screw 22. On the other hand, the guides 20 on both sides engage with the inner circumference of the handrail 2. and one end of the guide frame 1
9 into the groove 19b, and the other end is inserted into the glass panel 1.
The opening end between the 8th and 7th drains 20 is
It has a shape that fits into the gc, and is made of a plastic material such as nylon that has a low coefficient of friction.

In this case, the upper side members of the guide frame 19 and the guide 20 are efficiently housed within the inner circumferential space of the rail 2 in both vertical and vertical dimensions, and the most important fixing to the glass panel 18 is the groove 19a. The fastening force of the screw 22 using the notch 18a is used to ensure the fastening. In addition,
The guide 20 has an upper side 2 that is in strong contact with the rail 2.
0A1 side part 20B and lower side part 20C and no-ndrail 2
In addition to guiding the handrail 2 by having a vertical side portion 20D1 that contacts the open ear portion of the handrail and a lower surface portion 20E that closes the gap between the handrail 2 and the glass 18, the guide frame 19 has a convex portion inserted into the groove 19b. The portion 20a1 includes a convex portion 20b that fits into the concave portion 19C.

When the guide 20 is attached to the guide 7 frame 19, the guide 20 is opened as shown in the imaginary line in the state shown in FIG. 6, and is fixed by pushing in the direction of the arrow.

In this way, by arranging the parapet sap material such as the guide frame 19 and guide 20 within the inner circumference of the handrail 2, the downward extension of the handrail 2, which was a concern in the past, and the horizontal 1. Business trips to and zb) have completely disappeared,
Moreover, the guide frame 19 and the guide 20 can be securely fixed.

For this reason, the angle of incidence explained in Fig. 2 is expanded (according to the present invention, θ2 becomes θ2>θl), and energy saving (9) can be efficiently illuminated even with a light fixture (no lighting fixture 11). We can provide a comfortable user environment.

On the other hand, the protruding dimensions t, tb, which had conventionally been a problem in terms of safety and design, have been eliminated, and the effect in this respect is also significant.

〔Effect of the invention〕

According to the present invention described above, there is an advantage that a passenger conveyor that is bright and light, and has a high design quality and safety can be provided.
