Description

  The present invention relates to a passenger conveyor for circulating and moving a number of steps connected endlessly, and a passenger conveyor step used in the passenger conveyor.

  Conventionally, passenger conveyors such as escalators and moving walkways circulate and move many steps (steps) connected endlessly by a drive chain, and are provided on the outer periphery of the balustrade that stands on both the left and right sides of these steps For example, in the case of an escalator, a passenger boarded from the entrance on the lower floor is transported to the entrance on the upper floor.

  In such a passenger conveyor, a pair of passenger conveyor trusses are arranged opposite to each other so as to sandwich the step movably with a small gap between the left and right sides of the step. Passengers' feet may be caught in the gap. In addition, there is a risk that a foot or the like may be caught between adjacent steps.

  In order to call attention to passengers, in JEAS (Japan Elevator Association Standard), yellow caution signs with a width of 20 mm or more will be placed on both sides of the escalator steps and adjacent steps. Each escalator maker manufactures steps according to this.

  Usually, this yellow caution sign portion is formed of a synthetic resin and is detachably attached to a metallic step body. As a result, even if a passenger is caught, the attention sign portion is easily bent, and it is easy to remove or destroy the passenger so that the passenger can be rescued easily.

Conventionally, multiple narrow pattern bodies different from the step are bonded to multiple cleats (tread surface irregularities) in a form perpendicular to the longitudinal direction of the cleats, and the narrow pattern bodies are gathered together. A pattern in which a foot shape or the like is formed is known (see Patent Document 1). Patent Document 1 describes that, when a foot-shaped assembly is used, the position of a correct passenger on the tread can be displayed, and can also be used as a display for a dangerous portion.

  By the way, there is a method of widening the width of the caution sign so that the passenger can easily recognize the caution sign and guide the passenger to the inside of the tread. However, this method decreases the rigidity of the tread surface and increases the frequency of caution sign breakage, which not only increases the cost of repairing the step, but also reduces the safety of passengers. There is a fear.

  In addition, it is necessary to change the design of the metallic step body and the caution sign made of synthetic resin, which necessitates an initial investment in the production of the step body and the caution sign, for example, modification or new production of molds, etc. Resulting in.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and its purpose is to reduce the manufacturing cost without lowering the rigidity of the tread surface and to provide a passenger with a safety sign that has higher visibility than before.

  According to the second feature of the present invention, the guidance display part colored in the same color as the attention sign member and the attention display part is formed along the moving direction of the step on both side edges of the boarding board installed at the entrance. By being done, since a passenger can be guide | induced to the safe range of a tread when a passenger gets in, the safety sign whose visibility is higher than before can be formed.

  According to the present invention, there is provided a step for a passenger conveyor that includes a safety sign having a higher visibility than the conventional one and a safety sign having a higher visibility than the conventional one, without lowering the rigidity of the tread surface and suppressing the production cost. Passenger conveyors can be provided.

  Embodiments of a passenger conveyor step and a passenger conveyor according to the present invention will be described below with reference to the drawings. Here, an escalator will be described as an example of a passenger conveyor. In the drawings, the same portions are denoted by the same reference numerals and description thereof is omitted.

  With reference to FIG. 1, the whole structure of the escalator 1 concerning embodiment of this invention is demonstrated. The escalator 1 is installed in a building having upper and lower floors or outdoors, and conveys a load between the upper floor and the lower floor, and a plurality of steps (passenger conveyor steps) by a drive chain (not shown). 2 are connected endlessly, and the plurality of steps 2 are circulated and moved from one boarding / exiting port 5L to the other boarding / exiting port 5U. In the escalator 1 shown in FIG. 1, a passenger who has entered from the lower floor entrance 5L is transported to the upper floor entrance 5U. On the surface (tread surface) on which passengers of the plurality of steps 2 ride, a plurality of irregularities are formed in the traveling direction.

  A pair of passenger conveyor trusses 7 are installed on the left and right sides of the step 2 along the traveling direction of the step 2. The pair of passenger conveyor trusses 7 are arranged to face each other so as to sandwich the step 2 so as to be movable with a slight gap. A balustrade 3 is installed above each of the pair of passenger conveyor trusses 7, and a handrail 4 is arranged on the outer periphery of the balustrade 3. By moving the handrail 4 in synchronization with the step 2, a passenger who has boarded from the lower floor entrance 5L can be conveyed to the upper floor entrance 5U.

  At the entrance / exit 5L on the lower floor, the step 2 appears from below the entrance / exit board 5a installed at the entrance / exit 5L and moves toward the entrance / exit 5U on the upper floor. At the entrance / exit 5U on the upper floor, the step 2 enters under the entrance / exit board 5b installed at the entrance / exit 5U and rotates about 180 degrees toward the entrance / exit 5L on the lower floor inside the elevator (not shown). Move.

The comb 6U is fastened and fixed to the boarding / alighting plate 5b by a countersunk screw. A plurality of comb teeth are formed at the tip of the comb 6U, and the plurality of comb teeth mesh with the unevenness (cleat) of the tread surface of the step 2 in a non-contact manner, thereby getting on and off the passenger's feet and foreign objects on the step 2 It scoops up on the board 5b, and it prevents that a passenger | crew's leg | foot, a foreign material, etc. are pinched | interposed between the step 2 and the boarding board 5b.

  Similarly, a comb 6L in which a plurality of comb teeth are formed at the front end of the boarding / alighting plate 5a on the lower floor side so as to mesh with the unevenness of the tread surface of the step 2 in a non-contact manner is provided.

  With reference to FIG.2 and FIG.3, the specific structure of the step 2 of FIG. 1 is demonstrated. The step 2 according to the embodiment of the present invention includes a step body 21 and a caution sign member 22 made of synthetic resin fixed to both side edges of the step surface of the step body 21 and adjacent step side portions. FIG. 2 shows a state in which caution sign members 22 are attached to both side edges of the step surface of the step body 21 and adjacent step side portions, and FIG. 3 shows a state in which the step body 21 and the caution sign member 22 are separated. Yes.

  As shown in FIG. 3, the attention sign member 22 includes a left safety sign member 22 a fixed to the left edge of the tread surface 31 of the step body 21 and an adjacent step side safety sign fixed to the adjacent step side of the tread surface 31. It has a member 22b and a right safety sign member 22c fixed to the right edge of the tread 31. Each of the left safety sign member 22a, the adjacent step side safety sign member 22b, and the right safety sign member 22c is formed in a belt shape having a certain width, and the left safety sign member 22a, the adjacent step side safety sign member 22b, and the right safety sign member Concave and convex shapes are integrally formed on the surface of each step 22c in the traveling direction of the step 2. Further, the caution sign member 22 is made of a synthetic resin. The attention marking member 22 corresponds to a demarcation line.

  On the other hand, the step body 21 has a tread surface 31 on which a passenger rides and a riser surface 32 formed at a step portion between adjacent steps. A plurality of screwing portions 35 for attaching the caution sign member 22 are formed on the outer peripheral part of the tread surface 31 of the step body 21, specifically, the part to which the caution sign member 22 is attached. Are formed on the inner portion of the caution sign member 22 and the riser surface 32. The step body 21 is made of, for example, an integral die-cast using aluminum, or a metal such as stainless steel or magnesium alloy.

For example, the caution sign member 22 may be colored yellow or red, and the caution display part 21a may be painted yellow. Further, the relationship between the width of the caution display part 21a and the width of the caution sign member 22 is arbitrary, but the width of the caution display part 21a is the same as the width of the caution sign member 22, or the width of the caution display part 21a. Is preferably wider than the width of the caution sign member 22. However, if the width of the caution display portion 21a, which is the yellow paint range, becomes larger than necessary, the function as a safety sign is reduced. Therefore, if the depth of a general tread is 400 mm and the length from the heel to the toe of an adult shoe is 300 mm, the caution display portion 21a and the caution display portion 21a are required to allow the adult shoe to enter inside the safety sign. The total width of the marking member 22 is appropriately about 40 to 50 mm.

  As shown in FIG. 4, not only the convex and concave convex upper surfaces formed on the tread surface of the caution display 21a, but also the convex side surfaces and the concave bottom surfaces are painted. Thereby, it can suppress that a coating will be removed by friction with a passenger's shoes.

As shown in FIG. 5, in the lower floor entrance / exit 5L, the step 2 appears from below the entrance / exit board 5a and moves toward the entrance / exit on the upper floor. The unevenness formed on the tread surface of the step 2 meshes in a non-contact manner with a plurality of comb teeth formed on the comb 6L provided at the front end of the boarding / alighting plate 5a. The boarding / alighting plate 5a includes a plurality of boarding / alighting plates 5a ₁ , 5a ₂ , 5a ₃ , 5a ₄ arranged in the traveling direction DS of the step 2.

  A pair of passenger conveyor trusses 7 a and 7 b are installed on the left and right sides of the step 2 along the traveling direction DS of the step 2. The pair of passenger conveyor trusses 7a and 7b are arranged to face each other so as to sandwich the step 2 so as to be movable with a slight gap. A balustrade is installed above each of the pair of passenger conveyor trusses 7a and 7b, and handrails 4a and 4b are arranged on the outer periphery of the balustrade.

Are formed along. Specifically, first guide display portions 31a and 31b colored in the same color tone (red or yellow) as the attention marking member 22 are formed on both side edges of the boarding / alighting plate 5a along the moving direction DS. The first guide display portions 31a and 31b are arranged on the same line as the caution sign member 22, respectively. The widths of the first guide display portions 31a and 31b are substantially equal to the width of the caution sign member 22.

  Second guide display portions 32a and 32b colored in the same color tone (yellow) as the caution display portion 21a are formed along the movement direction DS inside the first guide display portions 31a and 31b. The second guidance display portions 32a and 32b are arranged on the same line as the caution display portion 21a, and the widths of the second guidance display portions 32a and 32b are substantially equal to the width of the caution display portion 21a.

  In FIG. 5, the guidance display portions 31a, 31b, 32a, and 32b are formed on the boarding / alighting plate 5a and are not formed on the comb 6L, but may be formed on the comb 6L.

  As described above, according to the present invention, the following effects can be obtained.

  By providing the caution display portion 21a on the inner side of the caution sign member 22 on the tread surface of the step body 21, the width of the caution sign member 22 made of synthetic resin is not changed, so that the rigidity of the tread surface does not decrease. Further, since the design of the step body 21 and the caution sign member 22 is not changed, the manufacturing cost does not increase. Furthermore, since the caution display part 21a is provided inside the caution sign member 22, the visibility as the caution sign is further improved. Therefore, it is possible to provide the step 2 provided with a safety sign that has a lower manufacturing cost and higher visibility than the conventional one without reducing the rigidity of the tread surface.

  The caution indicator 21a is painted in a different color from the caution indicator member 22, for example, the caution indicator member 22 is colored red and the caution indicator 21a is painted yellow, so that the danger level is gradually increased. A safety sign to be displayed can be formed. By making the caution sign member 22 red, it is possible to strongly appeal to the passengers that it is dangerous to get on the caution sign member 22, and a highly safe escalator can be provided. In addition, when the caution sign member 22 is worn in yellow, the width of the yellow safety sign composed of the caution display part 21a and the caution sign member 22 is wider than before, and passenger visibility is improved.

  The inside of the caution display portion 21a on the tread surface is painted in a blue or green color tone. As a result, the tread surface changes in order of yellow-blue (or green) or red-yellow-blue (or green) from the outermost edge, so that the area where passengers can get on and off safely is displayed more clearly. Can do.

  On both side edges of the boarding / alighting board 5a installed at the entrance / exit, guide display parts 31a, 31b, 32a, 32b colored in the same color as the attention sign member 22 and the attention display part 21a are along the moving direction DS of the step 2. Is formed. Thereby, since a passenger can be guide | induced to the safe range of a tread when a passenger gets in, the escalator which is safer than before can be provided.
