Description

[Detailed Description of the Invention] The present invention relates to a passenger conveyor such as an escalator or an electric road, and particularly relates to a parapet structure with a simplified structure.

Passenger conveyors have been widely used as essential transportation equipment within buildings, but
Recently, there have been a wide variety of requests regarding this equipment, including energy saving, safety, and a light design.

As shown in FIG. 1, the conventional passenger conveyor is composed of a rotary body consisting of an endlessly arranged rotating step 1 and a movable handrail 2, 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 movable handrail, a movable handrail frame 10, lighting fixtures 11, and other parapet top sap materials are arranged. Inside the movable handrail frame (generally made of stainless steel) 10, there is a gasket 12 that protects the glass panel 5, and a lamp 13 and a cover 14 that grip the glass panel and that constitute the lighting equipment 11. A support body 15 is provided, and a push plate 17 is further provided to this support body 15 to be fastened with bolts 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 circumference of the movable handrail 2 consisting of the decorative rubber part 2a and the cotton canvas part 2b, and is fixed to the movable handrail frame 10 with bolts (not shown). Next, the movable handrail frame 10 has a height h that is 2 to 3 times the size ratio of the height h _a of the movable handrail 2, and in the lateral direction extends from the side edge of the movable handrail 2 to the outside. Usually, l a and l _b protrude inward (generally 10 to 50 mm for both l _a and l _b ), and the l _a side is used for storing the lighting fixture 11 _, or the l _b side is used for holding the glass panel 5. It is used for.

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

Generally, when excluding the lighting fixture 11 shown in FIG. etc.) are usually not modified. In a passenger conveyor that does not use such a lighting fixture 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 movable handrail 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 a situation may occur in which 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 moving 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 movable handrail frame 10 (point P), making it difficult to grasp the movable handrail 2, as shown in FIG. Become.

If an attempt is made to grasp the moving handrail 2 in such an unreasonable condition, it is extremely dangerous because the feet may approach the skirt guard 8 and cause an accident when it is pulled in around the step 1.

Furthermore, in terms of design, there is a problem in that wear particles R of the movable handrail 2 accumulate on the upper surface of the movable handrail frame 10. This abrasion powder R is made of iron materials and rubber materials used in the drive system of the moving handrail 2, and the cotton canvas portion 2b.
As a public facility, this abrasion powder R causes a sense of uncleanness and stains passengers' clothes, which cannot 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 conservation, safety, and design.

In order to improve the above-mentioned problems, the present invention efficiently brings light onto Step 1 in a parapet configuration that is not equipped with lighting equipment such as lamps or covers, and also improves safety and reliability based on a light design sense. This invention was made to provide a clean passenger conveyor with a high level of cleanliness, and particularly relates to a balustrade structure that can reliably maintain the fastening strength of the upper end of the glass panel.

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

4 and 7, the drive mechanism of the rotating step 1, the structure of the main body 4, and the lower parapet saplings such as the inner deck 6, outer deck 7, and skirt guard 8 are the same as before. In the invented embodiment, a movable handrail guide frame 19 having a fitting groove that grips the upper end of the glass panel 18 (corresponding to the conventional glass panel 5) and a support portion that guides and supports the movable handrail 2, and the outer periphery of this guide frame 19. A major feature is that the upper side of the parapet is made up of guides 20 etc. arranged along the railing.

Here, to explain the structure of the upper side of the balustrade in detail, the guide frame 19 is continuously provided over the entire length of the balustrade, and the guide frame 19 is provided with a gasket provided to cover the upper end (both sides and upper side) of the glass panel 18. 21, the groove 19a is fitted into the upper end of the glass panel 18. Further, the details of the portion for tightening the guide frame 19 are as shown in FIGS. 6 and 7. The tightening screws are provided in a notch 18a (width J ₁ , depth
J ₂ ) so that the groove 19a is sandwiched between the head of the screw 22 and the nut 23. This groove 19a (width W ₁ ) is penetrated by a screw 22 and is provided with a separation piece 24 having a width W ₂ (W ₁ >W ₂ ), and furthermore, a movable handrail guide frame above this separation piece 24 is provided. A caulking groove 19b having a long width δ and length N is provided in the center of the upper surface of the support portion 19 along the longitudinal direction of the guide frame. This caulking groove 19
b communicates with the groove 19a. Then, as this screw 22 is tightened, the guide frame 19
The glass panel 18 and the gasket 21 are made to shrink as shown in the phantom line in FIG. 7, and the glass panel 18 and the gasket 21 are tightened by the shrinkage. Note that this caulking groove 19
b indicates that the tightening force of the screw 22 is
This is provided to prevent the upper side from being wasted due to deformation and to make the tightening force of the screw 22 effectively act on the clamping of the glass panel 18.
This has the effect of transmitting stable tightening force. On the other hand, the separating piece 24 has a cylindrical shape that covers the outer periphery of the screw 22, and is provided to prevent the groove 19a (W ₁ ) from shrinking excessively. This prevents further tightening and limits excessive tightening of the glass panel 18. Further, the separation piece 24 is colored in a different color from the glass panel 18, guide frame 19 and screws 22, for example red, to eliminate the problem shown in FIG. That is, by covering the outer periphery of the screw 22 as shown in FIG.
It is covered by a crimping groove 19b and is arranged so that it can only be seen from the outside through the caulking groove 19b. For this reason, there is a concern that they may be inserted separately as shown in FIG. 8, which may eliminate the effect of the separating pieces 24.

Here, by coloring the separation piece 24, as shown in FIG.
The position (intervals P ₁ and P ₂ ) of the separation piece 24 with respect to a can be confirmed by looking from the outside and identifying it, which solves the problem as shown in FIG. 8.

As mentioned above, the glass panel 1 with screws 22
8 and the guide frame 19 are securely fastened without any displacement or insufficient tightening force.

On the other hand, the guides 20 on both sides engage with the inner periphery of the moving handrail 2, and one end thereof is fitted into the groove 19c of the guide frame 19, and the other end is an open end between the glass panel 18 and the moving handrail 2. The material is made of plastic such as nylon, which has a low coefficient of friction.

In this case, the guide frame 19 and the guide 20
The upper side member is efficiently stored in the inner peripheral space of the moving handrail 2 in both the horizontal and vertical dimensions, and the most important connection to the glass panel 18 is ensured by the screws 22 and the groove 19b. It will be held in Note that the guide 20 is easily installed without falling off by fitting into the groove 19c and contacting the lower end of the guide frame 19 after the screw 22 is fastened.

In this way, by arranging the guide frame 19, guide 20, separation piece 24, etc. on the parapet sap material within the inner circumference of the movable handrail 2, the downward extension of the movable handrail 2 and the horizontal (l, and l
_(b ) The protrusion on the part is completely eliminated, and furthermore, the screw 22 and separating piece 24 are correctly assembled in the fastening part, and the strength can be reliably maintained, so reliability is improved.

For this reason, the angle of incidence explained in FIG. 2 is expanded (according to the present invention, θ ₂ and θ ₂ >θ ₁ ), and even an energy-saving balustrade (without lighting fixtures 11) can be efficiently illuminated, providing comfort to passengers. We can provide a comfortable usage environment.

On the other hand, the protruding dimensions l _{a and} l _b , which conventionally caused problems in terms of safety and design, have been eliminated, and it can be said that the effect in this respect is also great.

According to the present invention explained above, it is bright and light,
It also has the advantage of providing a passenger conveyor with good design, safety, and reliability.
