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 particularly relates to a safe and highly transparent parapet structure.

[Background of the invention]

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

As shown in FIG. 1, 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, and stationary bodies such as a handrail 3 and a main body frame 4.

As shown in FIGS. 1 to 3, the parapet 3 includes a glass panel 5 supported by a main body frame 4. A parapet lower sap material such as an inner deck 6, an outer deck 7 and a skirt guard 8, and
A guide 9 for guiding the handrail is provided on the upper side of the glass panel 5. Handrail frame 10. Balustrade for lighting fixtures 11, etc." Consists of two sap materials. And the handrail frame (
Inside the JO (generally made of stainless steel), there is a gasket 12 that protects the glass panel 5, and a support 15 that grips the glass panel and supports the lamp 13 and cover 14 that constitute the lighting fixture 11. , furthermore, this support 1
A press plate 17 is provided to fix the glass panel 5 by fastening the holes 1 to 16 to the glass panel 5.

- The guide 9 on one side engages 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 10 with bolts (not shown). The hunt rail l/-1s1.0 has a height b that is two to three times the height ha of the handrail 2, and in the lateral direction, Q from the side edge of the handrail 2 to the outside.
a, Qb protrudes inward, and the Qa side is used for storing the lighting fixture 11, and the Qb side is used for gripping the glass panel 5.

In contrast to such conventional balustrade configurations, there has recently been an increasing need for energy-saving designs with light designs that exclude the number J and lighting fixtures 11.

Generally, in order to exclude the lighting fixture 11 shown in FIG.
Usually, the inside of the railing is covered and the members of the balustrade body (such as the handrail frame 10) 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 provide sufficient light for the feet), but the conventional pan 1 to rail frame 1o [2] It is extremely inconvenient.

That is, as shown in FIG. 2, when the brightness of the ceiling light X is guided to the step 1 side through the glass panel 5 as indicated by the arrow M, the protrusion dimension Qa of the handrail frame 1° and the height 11 are the incident light beams. The angle o1 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, there are also issues that need to be resolved in terms of safety and design with conventional man-con hair.

In terms of safety, it is conceivable that a child or the like may not be able to grasp the handrail 2 reliably. That is, as shown in Figure 3, the height of the railing is set at 650-75 ollllllI to prevent passengers from falling, and the height of the railing is set to a suitable height for passengers of school age and younger. It has become. but,
In the case of young children, in addition to the problem of height I-1, part of the hand Q may come into contact with the corner of the handrail frame 10 (point P), making it difficult to grasp the hunt rail 2, as shown in Fig. 3. becomes.

If an attempt is made to grasp the handrail 2 in such an unreasonable condition, the foot will come close to the 8 parts of the skirt guard and be pulled in around the step 1, causing an accident, which is extremely dangerous.

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 mixed powder of iron materials and rubber used in the drive system of the handrail 2, and the cotton kimpus part 2b.
As a public facility, this wear powder R is a waste and stains the clothes of passengers.

Here, a conventionally known example is US Patent No. No. 03989.
133, but the structure is largely the same as the conventional parapet structure illustrated in the main text, and there is room for improvement.

For this reason, the inventors have proposed a parapet configuration as shown in Figure 4 and below. This configuration allows for more efficient daylighting in step 1, creating a product that is significantly improved in terms of safety and aesthetics. It is protruding concavely.

That is, in FIGS. 4 and 5, the structure of the drive mechanism 11 of the rotating step 1, the structure of the closed frame part 4, and the lower parapet sap members such as the inner deck 6, the outer deck 7, and the skirt guard 8 are the same as before. However, in this configuration, a guide frame 19 (generally made of extruded aluminum material) that grips the upper end of the glass panel 18 (corresponding to the conventional glass panel 5) and guides the handrail 2, and this guide frame 11
The kite 20 arranged along the outer periphery of the parapet 19 constitutes the upper side of the parapet.

Here, the guide frame 19 on the upper side of the balustrade is provided continuously over the entire length of the balustrade, and its R/g] 9 a is fitted into the upper end of the glass panel 18. The screws 22 and nuts 23 that have been previously cut into the guide frame 19 are cut into the notches (width JI + depth J
2)], 8a and the notch 21a of the gasket 21, and is fixed by tightening the screw 22.

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 inserted into the opening between the glass panel 18 and the handrail 2. It has a shape that covers the end, 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. 1.8 This is ensured by the tightening force of the screw 22 using a. In addition,
After the screws 22 are fastened, the guide 20 is fixed without falling off by fitting into the groove 19b and contacting the lower end of the guide frame 19, and this configuration is continuously arranged in the section where the handrail 2 runs.

These recent balustrade configurations allow for daylighting (energy saving),
It has been well received in terms of safety and aesthetics.

However, in the balustrade configurations shown in FIGS. 4 and 5, there is a phenomenon in which the longitudinal dimension of the guide 20 expands or contracts depending on the level of heat generated when the handrail 2 slides, and this problem needs to be improved. That is, the guide 20 is made of a plastic product such as nylon and has the property of expanding and contracting depending on the level of heat, but since this guy 1-20 is in direct contact with the handrail 2,
The handrail 2 is arranged so that it can easily expand and contract depending on the magnitude of sliding resistance, changes in temperature, etc. Here, guide 2
Although a change in the elongation direction of 0 does not pose a major problem, a change in the shrinkage direction creates a gap as shown by the symbol in FIG. 6, which poses a safety problem. This gap may cause lacerations if a passenger accidentally hits the corner of the joint between guys i to 20 while grasping the handrail 2, so it is desirable to reduce this gap to increase safety. .

[Purpose of the invention]

An object of the present invention is to provide a balustrade structure that is not affected by heat caused by sliding of a handrail.

[Summary of the invention]

The gist of the present invention is a step that is arranged in an endless manner and rotates, a handrail that rotates synchronously, a guide frame, a gasket, a guide, etc. provided at the upper end of the parapet provided on both sides of the step. The lower end of the packing is shaped to cover the lower end of the guide.

[Embodiments of the invention]

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

In FIGS. 7 and 8, the guide frame 19 is arranged on the inner periphery of the handrail 2. The configuration of the guide 20, screws 22, etc. is the same as in the conventional FIGS. 4 and 5, but in the present invention, the conventional gasket 21 has a substantially U-shaped portion 24a that covers the upper end of the glass panel 18, and this lower end. Cover the lower end of the guide 20 and insert the handrail 2 from the side of the glass panel 18.
The gasket 24 is characterized in that it has a lower end portion 24b that extends close to the . Patsukin 24 is the same as before,
It engages with the groove 19a of the guide frame 19, and its 1I18
The U-shaped portion 24a has a fastening structure in which a notch 24c is provided at a position where the screw 22 is placed. The gasket 24 is in contact with the glass panel 18 and the groove 19a, but does not come into contact with the handrail 2 at all, so it is completely unaffected by the heat caused by sliding of the gasket 24, and furthermore, the joint portion of the guide 20 is located at this lower end. Since the part 2/Ib is completely covered, the structure is such that it is not exposed in the conventional gap. Also,
The lower end portion 24b is only slightly exposed from one side of the handrail 2, and has a configuration that does not interfere with the transparency of the balustrade, and completely disappears in the gap at the upper end of the balustrade that poses a safety problem.

〔Effect of the invention〕

According to the present invention, it is possible to solve the conventional problems and provide a handrail for a passenger conveyor that is safe and has excellent transparency.
