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 that improves the running path of a handrail near the entrance/exit.

[Background of the invention]

Passenger conveyors such as escalators have been used as service equipment in various commercial buildings, but recently they have begun to be used in various fields such as office buildings, urban transportation, and pedestrian bridges. For this reason, efforts are being made to improve comprehensive functions such as unique designs, energy saving, and space saving, with safety as the top priority for the general public.

The general configuration of a passenger conveyor is shown in FIG. The main parts consist of a movable part consisting of steps 1 and handrails 2 that are arranged in an endless manner and run, a floor plate 3 and a comb 4 that constitute the entrance and exit, and stationary parts such as the handrail 5 and the frame part 6. , all these parts are supported under the building floor.

The conventional structure near the bottom shown in FIG. 3 has the shape, dimensions, and arrangement relationship shown in FIG. 4. That is,
The step 1, which is a moving part, appears and disappears at a comb 4 provided at the rain entrance, and the handrail 2 is structured to be reversed at the top X at the end of the handrail 5. Furthermore, the shape of the running path of the handrail 2 includes a curved part A formed by curvature radii R1 and R2, a horizontal part B parallel to the floor plate 3, and a step 1.
It usually consists of a curved section C where the curve transitions to a side channel, and there is a horizontal section of 500 to 1,000 mm between the terminal end Aa of this curved section A and the tip 4a of the comb 4. It is provided.

In the above dimensional relationship, the curvature R that forms the curved part A
, R2 are determined by the selection of the railing design, and the lengths of the horizontal portions B and VD are determined from the positional relationship between this terminal line Aa and the comb 4 determined by the travel trajectory in step 1. The horizontal sections B and D are used to ensure a stable posture for passengers while timing their boarding (or disembarking).

Here, the value of 1 curvature R1 is determined by the curvature followability of the handrail 2, and is generally set to a minimum of about 300 mm, taking into account the reduction in life due to continuous bending. It is. hand rail 2
The life of the curved part C
Concave bends such as curvature R1 and sudden changes in the running path near the terminal line Aa that suddenly changes to the horizontal part B are affected by increases in sliding resistance and bending resistance, and the life of the handrail 2 itself is increased. The key point is to improve the running route b).The shape of the curved section A made up of the above-mentioned curvature R work may be made up of two curvatures or a single curvature as shown in Figure 4. In addition, as shown in Japanese Patent Publication No. 57-57394, there is also one that consists of a small diameter curvature part S□tSa and a vertical part S3.

Further, a structure in which the single small-diameter curvature portion 11 includes a slope portion t2 is also known. However, these small diameter curvature portions 5
The end of the parapet made of lttl has a radius of 20
The actual situation is that the handrail 2 cannot match this dimension in terms of lifespan. The reason for this is that if the parapet height H is practically set to 800 to 1000 mm, the height of 51ttt will inevitably be 300 mm or less, and the life of the handrail 2 will be significantly reduced.

As mentioned above, the shape of the terminal top part X of the handrail 5 should be considered with the life of the handrail 2 as the most important consideration, and the small diameter curvature part S1
．． It can be seen that priority should not be given to changes in design needlessly, such as by providing t1.

Next, safety problems in the terminal configuration of the balustrade 5 illustrated in FIG. 4 will be explained.

Conventionally known parapet structures include Japanese Patent Application Laid-Open No. 57-1805
There are two types as disclosed in US Pat. No. 83, FIG. 5 and FIG. 6.

The one in FIG. 5 is a lighting device that guides the handrail 2 by placing a gasket 8, a handrail frame 9° guide 10 on the upper edge of the lath panel 7 constituting the handrail, and also consists of a lamp 11 and a lamp cover 12. I support 13. This is a so-called passenger conveyor with parapet lighting. In addition, lighting equipment W
This type is also called a balustrade with a handrail frame because the cover 2 closes the opening of the handrail frame 9 when the balustrade 113 is not provided. The type shown in Fig. 5 has the transparent part of the glass panel 7 reduced by the height h of the handrail frame 9 relative to the height H of the balustrade, and has a solid design sense. There are some inconveniences when using it. The first reason is that, as shown in Figure 4, the height h of the parapet suddenly increases to about 1 meter from the end of the parapet, making it impossible for short passengers to run up (preparatory movements for boarding and disembarking).

The second reason is the same as above, the height H of the parapet is about 1 meter (9
The third reason is that the height of the handrail frame 9 is higher than the height of the handrail 2, and it protrudes further downward (h-h). , ), and protrudes laterally across Ω, , Ω, so that when a particularly short passenger tries to grasp the handrail 2, the finger Q touches the inner corner P of the handrail frame 9. This can cause the upper body to be pulled in the opposite direction, increasing the danger.

Furthermore, the one in Figure 6, which is the most popular balustrade configuration these days, is also similar to the one shown in Figure 1 above. The second reason, safety concerns, remains. This parapet includes a guide frame 15 for guiding the handrail 2 on the upper edge of the glass panel 14, and a guide 1 for guiding the handrail 2.
6 is provided, while penetrating the cut 14a of the glass panel 14 to the lower side 15a of the guide frame 15 and the gasket 16.
It is equipped with bolts 17 etc. that hold the handrail 2 from both sides, and includes a member for guiding the handrail 2 and a member for guiding the handrail 2.
The handrail 2 is housed within the height of the inner periphery of the handrail 2 so that it hardly protrudes from the lower side of the handrail 2.

As described above, the terminal line A of the terminal top X of the parapet.

In the conventional balustrade configuration in which only the horizontal part B exists between and the curved part C (approximately the horizontal part between A and 48), 1. In order to extend the life of the handrail 2, the curved part A It is necessary to increase the radius of curvature forming the terminal line A and avoid sudden changes in the running route near the terminal line A.

2. It is necessary to reduce the height H of the parapet for short customers such as young children. In particular, when a passenger walks on the floor of a building, his or her hand, which is located below the waist (around the thigh), suddenly rises to a height of about 1 meter at the entrance of the passenger conveyor, and yet only a short distance (horizontal part D) ), it is not only young children but also elderly people and adults with slow movements who are unable to prepare for Step 1, leading to accidents such as falls.

There are issues such as:

There is a need for an improvement measure that satisfies the condition in item 1 mentioned above, improves safety in terms of item 2, such as preventing falls, and also expresses a different feel from the design.

[Purpose of the invention]

SUMMARY OF THE INVENTION The object of the present invention is to provide a railing for a passenger conveyor which eliminates the above-mentioned drawbacks of the conventional structure and which improves the service life of the handrail, increases safety and changes the design.

[Summary of the invention]

In order to achieve this object, the present invention provides a gentle slope where the end top side is lower between the end top part where the handrail is reversed and the comb, so that the handrail is reversed near the end of the handrail. It is composed of a curved part, the inclined part, and a horizontal part parallel to the upper surface of the floorboard, and the curved part, the inclined part, and the horizontal part form a running path for the handrail.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the configurations of the moving part and the stationary body are almost the same as in the past, and the same parts are given the same reference numerals. However, in the present invention, the height of the top X part at the end of the parapet is Parapet height I (lower than top height H, height R2 of Toshiko is defined as curved part A1, which is connected by two curves R1 and R4, while terminal line A of curvature R3, and floor surface 3 The feature is that an inclined part K is provided between the parallel horizontal part B□ and the slope part K which is gently inclined and whose top part X side is lower. is provided in the same manner as before, but there is a terminal line B of the horizontal portion B1 at a position horizontally separated by D□ from the tip 4a of the comb 4, and it is connected to the inclined portion by a curvature R. There are also characteristics.

Here, the handrail 2 is of course guided by the handrail frame 9 shown in FIG. 5 and the guide frame 15 shown in FIG. 6 (this balustrade structure is adopted in FIGS. 1 and 2). , the handrail frame (or guide 1
0) 9 and a guide frame 15 (or guide 16) are arranged.

The arrangement of the sloped part K near the end of the handrail 18 in this way has the following advantages: 1. First, passengers who come to the end top X and try to board the passenger conveyor are placed at a position lower than the conventional height H of the handrail (height). SaHk
) has the advantage of being able to grab the handrail 2. Then, completely grasp the handrail 2 in the inclined range BB, then horizontal part B1.
You can prepare for boarding and step 1. This advantage eliminates the problem described in FIG. 5 and is suitable for safety for young children and the elderly.

2. Second, it is effective in reducing the bending resistance of the handrail 2. That is, as explained in FIG. 4, the terminal line A,
There is no sudden bending change in the vicinity, and the handrail 2 gently returns to a straight line from the curvature R1 portion, which is subject to severe bending, to the slope portion, and then transitions to the horizontal portion B1, so running is easy.

Similarly to Section 3.2, the processing conditions can be relaxed even when manufacturing the guide frame 15, for example. this is,
Similar to the sudden change in the running trajectory of the handrail 2, when bending the guide frame 15, it is better to bend the guide frame 15 at a place close to horizontal (slanted part
), it is easier to process if it becomes naturally horizontal.

Additionally, the design of the balustrade will also be unique.

As described above, the provision of the inclined part K near the end of the handrail 18 and the formation of the running path for the handrail 2 in the curved part A1 and the inclined part and in the horizontal part B1 has the advantages of safety, longevity, and economy. It has the advantage of being able to make changes in the design of the parapet.

In addition, the above-mentioned inclined part is not limited to the linear part shown in the example.
It is also possible to configure it with a large diameter curve like RR in FIG. 2, and the same effect can be achieved in this case as well.

[Effects of the Invention] The present invention has the advantage of providing a passenger conveyor that is more effective than ever in terms of passenger protection, lifespan, and design.
