Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an escalator balustrade, and more particularly to an escalator balustrade with an improved handrail frame that is attached to the outer periphery of a balustrade panel and guides and supports a handrail.

In general, an escalator consists of a step 1 for carrying passengers, and balustrades 2 erected on both sides of the step, as shown in Figures 1 and 2.
and a handrail (movable handrail) 3 that is attached to the handrail 2 and moved in synchronization with step 1, and the handrail 2, which is a stationary body, has a handrail frame 4 and an outer sleeve deck. 5, a ledge 6, a skirt guard 7, a parapet panel 8, etc. In order to improve safety and design, the handrail 2 is generally provided within the handrail frame 4 so that the lamp 9 is protected by a cover 10, or has a structure in which pillars 11 are provided to support the handrail frame 4. In order to give a sense of transparency and improve the design effect, the structure is such that the rigidity of the handrail panel 8 is increased to support the handrail frame 4 without providing the pillars 11.

Here, in the conventional escalator, it is necessary to project the inner end surface of the handrail frame 4 of the handrail 2 inward by the gap A from the inner end surface of the handrail 3 due to the barrier structure (not shown) of the handrail 3. Therefore, the width dimension B of the handrail frame 4 was made approximately 30% larger than the width dimension C of the handrail 3. This gave the product a sense of weight, but it also had the problem of high material and processing costs due to its large size.

Therefore, recently, in response to social demands such as small space, energy saving, material saving, etc., major changes have been made to the handrail rib structure, and as a result, the gap A mentioned above is no longer necessary. It's here.

Although not shown in the drawings, a parapet has been proposed in which the overall width of the escalator can be shortened without changing the step width, thereby reducing the installation area. Simply stated, this is a configuration in which the width of the handrail frame is narrower than that of the handrail, and the balustrade panel is located at the center of the cross section of the handrail frame, giving the balustrade a slim design.

However, in a handrail with such a configuration, the inner end surface of the handrail frame is recessed from the inner end surface of the handrail, so it is difficult for passengers to lower the escalator in the new part where the handrail is reversed, which is the upper and lower escalator entrances. This may increase the danger of cargo, etc. coming into contact with the handrail part that moves in the opposite direction to the direction of travel. Because the escalator is large, there is a problem that dangerous situations can occur if passengers' luggage collides with the stepped part, causing danger and discomfort to passengers, and damage to the inside of the escalator railing due to collisions with luggage, etc. There was a problem.

In addition, if we try to store lighting lamps inside the handrail frame, it becomes necessary to widen the width of the frame so that it protrudes outward.Currently, the specifications for whether or not lighting is provided are almost 50/50, depending on the customer's building situation. ``The handrail frame has to be shaped into a protruding or recessed shape each time, and it is not always possible to obtain a standardized handrail with a slim design. Furthermore, due to the rigidity of the panel, when using a thin panel, pillars must be provided, which causes the pillars to protrude outward from the handrail frame, resulting in the design effect not being much different from conventional panels. there were.

On the other hand, conventional handrail frames for escalator balustrades were manufactured by aluminum extrusion molding to obtain the desired cross-sectional shape, but there was a problem in that the surface was easily scratched and the appearance was poor. For this reason, the idea of manufacturing handrail frames using thin plates such as stainless steel plates, which are superior in terms of durability and luxury, has recently become widespread, instead of the conventional aluminum extrusion molded products.

However, it is difficult to use such thin plates to form a handrail frame with a cross-sectional shape similar to that of conventional aluminum extrusion molded products, requiring fairly complicated processing, which increases costs, and the wall thickness is thin. There were problems in that it had low rigidity and was easily deformed by external force, making it difficult to maintain its function as a handrail frame in terms of strength.

This invention was conceived in view of the above-mentioned circumstances, and its purpose is to enable a handrail frame that can be easily formed using a thin plate, maintains a high level of strength, and is superior to conventional aluminum-based frames. Not only can it perform the same functions, but it is also safer and more aesthetically pleasing.Furthermore, the same handrail frame can always be used regardless of whether there is lighting or pillars, making it a standardized, slim, material-saving and smart design. The purpose is to provide escalator railings.

In other words, in order to achieve the above object, the escalator balustrade of the present invention has a handrail frame divided into an upper handrail frame having a substantially U-shaped cross section and a main handrail frame opening downward, each of which is formed from a thin plate. As a structure,
In addition, the main handrail frame is provided to have the same width as the handrail over the entire length, and is fitted into the main handrail frame to connect the upper end of the handrail panel to the main handrail via a gasket. A feature of the attachment is that a frame is provided to provide a reinforcing attachment for fixing the frame in a pinched state on one side toward the inner end surface of the frame.

With this configuration, the handrail frame of the parapet is divided into an upper handrail frame that has a substantially U-shaped cross section and a main handrail frame that opens on the bottom, so it is possible to use thin plates. ! It can be manufactured by simple molding without any rough processing, and it solves the problems of conventional aluminum extrusion molded products, where the surface is easily scratched and the appearance deteriorates, and it is also made of thin sheets. The handrail frame has low rigidity and is easily deformed by external force, but the thick frame that also serves as reinforcement is installed inside the main handrail frame. I fixed it by sandwiching it between the parts,
The handrail frame can maintain high strength and maintain a stable state without easily deforming, and can perform the same function as a conventional aluminum handrail frame. The main handrail frame is made to have the same width as the handrail over its entire length, and the upper end of the balustrade panel is fixed by the frame, so that the upper end of the parapet panel is fixed by the frame. In addition to being slim in terms of design, there are fewer steps at which baggage can get caught in the reversing sections of the upper and lower entrances, and it is both safe and aesthetically pleasing. It is easy to do and standardization is possible.

An embodiment of the present invention will be described below with reference to FIG. Note that FIG. 3 is an enlarged view of the main part of the escalator's handrail, and the rest of the structure is the same as that of FIGS. 1 and 2, so illustration thereof is omitted. In the figure, 12 is a balustrade, 13 is a handrail, 14 is a handrail frame of the balustrade 12, 15 is a balustrade panel, 16 is a lighting lamp, 17 is a lamp cover, and the handrail frame 14 is the balustrade panel 1.
As shown in FIG. 1, the handrail 13 is guided and supported along the outer periphery of the escalator, and is disposed along the entire length between the upper south side inlet part A of the escalator and the lower floor side inlet part A (not shown). . This handrail frame 14 is not made of a conventional aluminum extrusion molded product, but is made of a thin plate as shown. In other words, this handrail frame 14 has a divided structure into an upper handrail frame 14A having a substantially U-shaped cross section and a main handrail frame 14B having a roughly lip groove-shaped cross section opening downward, so that it can be easily formed from a thin plate. Then, the two are joined together as shown in the figure and connected by appropriate means. In addition, the handrail frame 14 made of such a thin plate has a drawback that it has low rigidity and is easily deformed by external force because of its thin wall thickness. Although some parts have been omitted, a frame 18 is fitted to the thick wall that also serves as reinforcement. In this installation, the frame 18 is fixed to each other by sandwiching the upper end portion of the balustrade panel 15 via a gasket 19 having a hat-shaped cross section. Although the structure for fixing the frame 18 to the upper end of the balustrade panel 15 via the gasket 19 is not shown in the drawings, the installation is carried out by conventionally known bolt tightening as already shown in Japanese Utility Model Publication No. 48-30397. .

Further, the main handrail frame 14B of the handrail frame 14 is formed so that its width dimension B' is the same as the width dimension C' of the handrail 13 as shown in FIG. It is provided so as to coincide with the inner end surface 13a.

Furthermore, the main handrail frame 14B is provided so that the gap (step) G between it and the inner surface 15a of the handrail panel 15 is as small as possible.

That is, as described above, when the main handrail frame 14B is fitted into the main handrail frame 14B, the upper end of the balustrade panel 15 is sandwiched between the frame 18 and the gasket 19. For installation between the inner end wall and the inner surface 15a of the balustrade panel 15, the wall thickness of the frame 18 part and the packing 19 part is kept to the minimum necessary, and the upper end of the balustrade panel 15 is attached to the main handrail frame. It is configured to be fixed as far as possible toward the inner end side from the center of the cross section of 14B. The wall thickness and installation of the main handrail frame 14B are as follows: Frame 18
The total required minimum wall thickness of the packing 19 is approximately 1
The gap G, which has the same dimension as about 2M, is reduced to within 1/6 of the width dimension C'≠82am of the handrail 13, which is set to the grip width of a normal human hand. . This is a slight step less than the thickness of a finger of a human hand.

The above-mentioned balustrade panel 15 is made of thick and rigid tempered glass with a thickness t1 of about 10 to 12 m, but as shown by the dotted line in Fig. 3, a thin reinforced glass with a thickness t2 of about 5 to 6 m is used. The handrail frame 14B is made of glass and is arranged to one side inward so that the gap G between the inner surface 15a' and the main handrail frame 14B remains unchanged. In the case of this thin board balustrade panel 15', it is necessary to erect a pillar 20 on the outside, but even if the pillar 20 has a width t3 similar to the conventional one, it is installed without protruding outside the main handrail frame 14B. becomes possible.

Further, when the illumination lamp 16 is not required, a flat back cover 21 is provided in place of the lamp cover 17. The lamp cover 17 and the back cover 21 have the same width regardless of the thickness of the parapet panel 15, 15', and are attached to a bracket (not shown) provided in the main handrail frame 14B of the handrail frame 14. It is designed so that it can be installed by engaging it.

With the above-described configuration, the handrail frame 14 of the balustrade 12 has a divided structure into an upper handrail frame 14A having a substantially U-shaped cross section and a main handrail frame 14B having a substantially lip groove-shaped cross section opening downward. It is said that
It can be manufactured by simple molding using a thin plate without complicated processing, and solves the problem of conventional aluminum extrusion products, where the surface is easily scratched and the appearance is poor. This makes it possible to improve durability and luxury. In addition, the handrail frame 14 made of a thin plate has low rigidity and is easily deformed by external force, but when installing a thick wall that also serves as reinforcement inside the main handrail frame 14B, the frame 18 is fitted. The said parapet panel 1 through the packing 19
5, the handrail frame 14 can maintain high strength and maintain a stable state without easily deforming, making it similar to conventional aluminum frames. It will be able to demonstrate its fence capabilities as a handrail frame.

In addition, since the main handrail frame 14B of the handrail frame 14 is arranged so that it has the same width as the handrail 3 and the inner end surfaces i4b and i3% of both sides match,
Passengers' luggage, etc. are unlikely to come into contact with the handrail 13 that is inverted at the end of the handrail at the upper and lower entrances of the escalator. Inner surface 15a.

Since the gap G with 15a' is very small, it is very unlikely that passenger's luggage will collide with the step.There will be no discomfort or sense of danger to the passengers, and safety can be ensured. become.

Moreover, when viewed from the front of the escalator, the handrail frame 14, the handrail panel 15 or 15', and the pillars 20 are hidden behind the handrail 13, resulting in a very slim and smart handrail with a high design effect.
Regardless of the various specifications requested by the customer, such as the presence or absence of the handrail frame 14 and the presence or absence of the lighting lamp 16, it is now possible to standardize and respond immediately without changing the shape of the main parts such as the handrail frame 14, reducing material costs and production costs. This enables savings such as:

As explained above, in the escalator balustrade of the present invention, the handrail frame can be easily formed using a thin plate, and the frame can be fitted into the handrail frame made of the thin plate to serve as reinforcement. Since it is fixed to the main handrail frame, it is possible to maintain high strength and perform the same functions as conventional aluminum ones, and it is also highly durable. The width of the handrail panel is the same as that of the handrail, and the upper end of the handrail panel is fixed by the frame. There are fewer steps at the reversing sections of the floor and lower floor entrances where baggage can get caught, and the design is both excellent in terms of safety and design.
It is easy to determine the presence or absence of lighting and the insertion and installation of pillars, making it possible to standardize the lighting and provide excellent lighting.
