Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a guide rail that guides a moving handrail arranged around the outer periphery of an escalator's parapet, and in particular to a guide rail made of a material with a low friction coefficient such as nylon in order to reduce the running resistance of the moving handrail. The present invention relates to a movable handrail guide rail having a structure in which a plurality of synthetic resin rail members made of a polymeric material are connected in a continuous manner.

[Technical background of the invention and its problems]

In general, escalator handrails are made to rotate around the periphery of the handrail in synchronization with the steps, allowing them to be directly touched by passengers' hands, so they maintain their aesthetic appearance for a long time and always run smoothly. It is essential that

Recently, as shown in FIG. 5, the guide rail that guides the movement of the handrail has been made of a metal core material 1 and a material with a low friction coefficient such as nylon that is fitted onto the outer peripheral surface of the metal core material 1 so as to accommodate the core material 1. A fastening bolt 6 is mounted on a rail support frame 5 having a substantially U-shaped cross section and fixed to a panel deck 4 on a balustrade panel 3.
It is attached by tightening and fixing at the handlebars, and is adapted to slide onto the inner periphery of the movable handrail 7, which has a downwardly facing C-shape with a flat horizontal cross section, and guide the movable handrail 7. Also, the core material 1
The man rail member 2 is divided into a plurality of pieces each having a length of 2 to 3 m in accordance with the joints of the rail support frame 3, and these pieces are joined to be continuous in the longitudinal direction.

By the way, in such a moving handrail guide rail, the fifth
As shown in the figure, steps X and Y often occur at the joint of the rail members 2 and 2 that are joined together.The steps are caused by errors in the manufacturing of the components and defects during assembly, but the installation The reality is that this cannot be prevented by simply tightening the fastening bolts 6, and the difference in level causes unreasonable force to be applied to the moving handrail 7, increasing its running resistance, shortening the life of the moving handrail 7, and This gives passengers a sense of discomfort while driving. Therefore, measures such as chamfering the joint ends of the rail members have been taken to smooth out the step, but there is a problem in that the chamfering work is troublesome and requires a lot of labor.

Therefore, in the movable handrail guide rail having the above configuration, as shown in FIG. 7, a core material 1 having the same length L as that of the rail member 2 is fitted into each rail member 2 by being shifted by a length A in the longitudinal direction. Then, one end 1a of the core material 1 is made to protrude from one end of the rail member 2, and a core material retraction space 2a is provided at the other end of the rail member 2, and each of the core materials is inserted into one end. When installing the member 2 on the outer periphery of the parapet as described above, one rail member 2 is attached at each joint.
One end 1a of the core material protruding from one end is inserted into the other end space 2a of the other rail member 2, and each rail member 2 is integrally joined one after another and connected in a continuous state while eliminating steps as much as possible. It's matching.

However, in that case, since the fitting between the rail member 2 and the core material 1 is moderately tight to prevent the difference in level, and each rail member 2 is long, the core material protruding end of each rail member 2 is connected one after another. It is troublesome and requires a lot of effort and time to connect the part 1a continuously by inserting it into the part 1a.In addition, as shown in the rail member 2 of the parapet upper curved part shown by R in FIG. Spaces 2a, 2a are provided at both ends, and both ends are simultaneously connected to the core protruding end 1a of another rail member 2.

Since it had to be inserted into 1a, installation was extremely difficult and troublesome.

[Purpose of the invention]

This invention was made in view of the above circumstances, and has extremely high performance, as it allows the core material to be inserted very easily at the joints of each rail member, and the steps at each joint can be reliably removed. The purpose of the present invention is to provide a moving handrail guide rail for an escalator that is easy to assemble and simple to assemble.

(Summary of the Invention) The escalator moving handrail guide rail of the present invention has the following features:
It is constructed by joining multiple synthetic resin rail members made of polymer material with a metal core inside in the longitudinal direction and fixing them to the support frame on the outer periphery of the escalator's handrail using fastening poles. In a movable handrail guide rail for an escalator that guides a handrail from the inside, an exposed core part is provided on the upper surface of the rail member, and one rail member at the joint part is moved by pushing through the exposed core part. It has a structure in which a core material is provided that extends from the inside into the other rail member and straddles both rail members.
After each rail member is completely joined in the longitudinal direction along the rail support frame, the core member can be easily moved and inserted so as to straddle each joint.

[Embodiments of the invention]

An embodiment of this decoy will be described below with reference to FIGS. 1 to 3. In the figure, 11 is a metal core material such as aluminum extrusion material, and 12 is a synthetic resin rail member made of a polymer material with a low coefficient of friction such as nylon in order to reduce the running resistance of the moving handrail. The length was 2 to 3 m, and multiple pieces were connected in the longitudinal direction.
The core material 11 is fitted into each rail member 12 as reinforcement. Up to this point, it is no different from the conventional one.

By the way, as shown in the figure, each of the above-mentioned rail members 12 has a cross-sectional shape that is upside down from that of a conventional one, and is formed into a substantially upward lip groove shape in cross section that opens the center of the upper surface over the entire longitudinal direction, and the center of the upper surface is open. The core material exposed portion 13 is defined as the core material exposed portion 13. More specifically, the rail member 12 has curved portions 12a, 12a having a substantially flat C-shaped cross section facing each other on both sides, and the lower surface portions of both front curved portions 12a, 12a are lowered by a step. The bottom plate part 12b is configured to fit comfortably on the rail support frame 5 having a U-shaped cross section shown in FIG. An engaging edge portion 12C912c is formed which is folded back into a cross-sectional shape, and the space between the two engaging edges 12c and 12C is opened upward as a core exposed portion 13.

On the other hand, the core material 11 has a flat hat shape in cross section, consisting of both side brim portions 11a, 11a and a bottom plate portion 11b disposed one step lower between the flanges 11a, substantially similar to the conventional one shown in FIG. It is a long piece, and is designed to tightly fit and be contained within the rail member 12 to provide reinforcement and support for the rail member 12. Note that both side flanges 11 of the core material 11
Engagement grooves 1c and 11G that fit into the engagement edges 12c and 12CtJX of the rail 12 on the opposing inner surfaces of a and 11a.
have. The reinforcing core material 11 is made 2B shorter than the length L of the rail member 12, and is fitted into the rail member 12 so as to leave a space of length B at both ends. A hole 14 for inserting a fastening bolt is formed together with the hole 12 .

Here, another core material 15 is included in the rail member 12. This core material 15 is for the joint between the rail members, and is made of the same material and has the same cross-sectional shape as the core material 11,
Both side flanges 15a, 15a, bottom plate portion 15b and engagement groove 1
5c and 15c, but the length is a little shorter than the above-mentioned 8 dimensions, and the first one is in the B-dimensional space at either end of the rail member 12.
As shown in the figures and FIG. 2, it is slidably fitted so that it can move in and out.

Therefore, in the case of the above embodiment, the required plurality of rail members 12 including the core material 11 and the core material 15 are successively continued in the longitudinal direction on the rail support frame 5 on the outer periphery of the parapet. They are lined up in the same way, and fastened to the rail support frame 5 by inserting fastening bolts into the respective pre-formed holes 14.

After the work is completed, the worker can tighten the rail member 12 by using the exposed core part 13 opened at the center of the upper surface of each rail member 12, either directly by hand or by holding a shell as appropriate. Core material 1 for short seams placed inside one end
5 is advanced and moved so that the core material 15 is fitted approximately half into the end space of the adjacent rail member 12 as shown in FIG. Make it so that it grows. This makes it possible to eliminate steps at each joint, significantly lowering the running resistance of the moving handrail and allowing for comfortable guidance. Moreover, as described above, each rail member 12
After fixing the guide rails on the rail support frame 5, the joining of their end parts is easily done by moving the short core material 15), so the installation of the guide rail is very easy, simple and requires less assembly work. It can be done in a short amount of time with labor. Also, there is no need to insert both ends of the last piece into the adjacent core materials at the same time as in the past, and all joints can be It becomes possible to easily and reliably join the core material.

FIG. 4 shows another embodiment of the present invention, in which the core material 11A for reinforcing the rail and the short core material 15a for the joint are substantially the same as those in the above embodiment, whereas the rail member 1
2A has a downward lip groove shape in cross section with the center of the lower surface open in the longitudinal direction so as to be upside down from that of the above embodiment, so to speak, the cross sectional shape is similar to the conventional one shown in FIG. ing. Here, a long hole-shaped core material exposed portion 1 is located near the center end of the upper surface plate portion 12Ab, which is disposed one step lower between the curved portions 12Aa and 12Aa on both sides of the rail member 12A.
3A is formed so that the core material 15A can be moved. This also provides the same effect as the above embodiment, and furthermore, in this case, the upper surface plate portion 12Ab of the rail member 12A is located above the core material, so that the engaging edge portion 12C and the engaging edge portion 12C shown in FIG. The grooves 11G and 15G are no longer necessary, which is advantageous in that the configuration is simpler.

The core members 15, 15A move forward and straddle the ends of both rail members at the joint, form bolt insertion holes as necessary, and fix them to the rail support frame with fastening bolts. It's okay.

(Effects of the Invention) Since the present invention is made as described above, the insertion of the core material at the joints of each rail member can be done very quickly, and there can be reliably eliminated the level difference at each joint. This is a hand guide rail for moving escalators that has high performance and is very easy to assemble on-site.
