Description

  The present invention relates to an improvement of a device attached to a passenger entrance of a passenger conveyor.

  4 to 6 show a conventional passenger conveyor, for example, an escalator entrance, and FIG. 4 is a longitudinal sectional view of the entrance in a direction parallel to the side surface, showing only one entrance 4 and the other side. The entrance / exit is similarly configured. 5 is a partial cross-sectional view taken along the line VV in FIG. 4 and FIG. 6 is a perspective view taken along the line VI-VI in FIG.

  4 to 6, a tread 2 having a groove 3 formed in the traveling direction is attached to the upper surface of the step 1. When a passenger is placed on the tread 2 and arrives at each entrance 4, the step 1 infiltrates into the lower part of the floor board 5. A comb plate base 11 is laid across the entry portion of the entrance / exit 4 directly above the tread plate 2, and both ends are fixed to a comb plate base support 16 extending from the main frame 15 by bolts 17. . The comb 13 is divided and attached to the upper surface of the comb plate base 11, and the right end comb 13 </ b> R is attached to the comb plate base 11 at the right end portion. The comb teeth 13b and 13bR projecting from the main body portions 13a and 13aR of the combs 13 and 13R mesh with the grooves 3 of the tread plate 2. Further, the main body portion 13aR of the right end comb 13R extends through the terminal skirt guard 8fR to the outside. The same applies to the left end portion of the entrance 4.

An inner plate 6 is erected on the left and right sides of the step 1, and a moving handrail 7 is attached to the upper end portion of the inner plate 6 and circulates together with the step 1.
A skirt guard 8 </ b> R that guides the passenger from one side to the other entrance / exit 4 is erected on the side of the step 1 from the inner bottom end of the inner plate 6. On the outside of the skirt guard 8R, a skirt guard bracket 18 is erected while being supported by a comb plate support 16. An angle 20 is attached to the skirt guard bracket 18 with a bolt 19, and the skirt guard 8 </ b> R is attached to the angle 20 with a screw 21. The inner deck 23 </ b> R is attached to the skirt guard 8 </ b> R through the packing 22 and to the angle 20 with the screw 24, and closes the gap between the skirt guard 8 </ b> R and the inner plate 6. The left side of the entrance / exit 4 is similarly configured.

The terminal skirt guard 8fR on the right side of the entrance / exit 4 is attached to the extension of the other intermediate skirt guard 8R with a screw 21 and the inner deck 23fR is attached to the upper part with a screw 24.
The end skirt guard 8fR, as indicated by reference numeral 8fR 'in FIG. 6, hangs down to the position where the right side portion of the step 1 is closed, like the other skirt guard 8R', and the main body portion 13aR of the right end comb 13R in the middle. The lower end rises on the top surface of the main body portion 13aR and further on the upper surface of the comb plate base 11 and reaches the open side of the entrance 4. The left side of the entrance / exit 4 has the same configuration as that on the right side.

Here, the comb teeth 13b and 13bR scoop up the passenger's feet on the tread board 2 and scoop out foreign objects such as pebbles caught in the groove 3 so that the step 1 is smoothly placed below the floor board 5 of the entrance / exit 4 It functions to infiltrate.
By the way, the comb teeth 13b and 13bR are formed of a synthetic resin so as not to damage the comb plate base 11, and may be damaged. The damaged comb 13 needs to be replaced promptly. In the case of the comb 13 attached to the intermediate portion, it can be easily attached and detached by the screw 14.
However, in the case of the right end comb 13R, as indicated by reference numeral 13R 'in FIG. 5, even if the screw 14 is removed, the main body portion 13aR abuts on the lower end of the terminal skirt guard 8fR, and the comb teeth 13bR are the protruding portions of the tread plate 2. Can not be removed.
Therefore, in order to remove the right end comb 13R, first, the screw 24 is removed to remove the inner deck 23fR, and further, the screw 21 is removed to remove the terminal skirt guard 8fR. Thereafter, the screw 14 is removed, the right end comb 13R is removed from the comb plate base 11, and a new right end comb 13R is attached by a procedure reverse to the above procedure.

In the passenger conveyor shown in FIGS. 4 to 6, it takes a long time to remove the terminal skirt guard 8fR and the inner deck 23fR in order to remove and newly attach the right end comb 13R.
Therefore, when a groove for attachment / detachment is formed in the comb plate base 11 outside the terminal skirt guard 8fR, and as shown in FIG. 5, one end of the right end comb 13R is lifted and inclined as shown by reference numeral 13R '. In some cases, the right end comb 13R can be attached / detached by removing the other end of the right end comb 13R into the attaching / detaching groove without removing the terminal skirt guard 8fR (see, for example, Patent Document 1).
However, the strength of the comb plate base 11 decreases due to the formation of the detachable groove.

FIG. 7 is a plan view showing the entrance and exit of another conventional passenger conveyor, in which the main body portion 13aR of the right end comb 13R is shortened, and between the right end of the intermediate portion comb 13 and the inner surface of the terminal skirt guard 8fR. A right end comb 13R is attached.
For this reason, the right end comb 13R is located inside the terminal skirt guard 8fR, similarly to the intermediate portion comb 13, so that it can be removed by removing the screw 14 and is easily attached and detached (see, for example, Patent Document 2). .
However, when the step 1 meanders due to aging and the end face of the right comb 13R comes into contact with the inner face of the terminal skirt guard 8fR, the terminal skirt guard 8fR must be retracted to avoid this contact. .
However, the meandering of the step 1 is unstable, and a gap δ may be generated between the right end comb 13R and the terminal skirt guard 8fR. If this gap δ is large, the appearance may be damaged, or objects may be pinched.
