  First, in Patent Document 1, the cleat portion at the tip of the step step portion is formed so as to be inclined to the tip, so that the passenger's toe is in contact with the portion, and the passenger feels uncomfortable. It is expected to move the foot, but in the height where the cleat part is inclined to the tip height, the higher it is, the more strange it feels, but the inclination angle becomes too large or the height It is necessary to consider that, when the height of the step is excessively high, the steps lined up in the front and back are in a horizontal state, and on the contrary, it causes a passenger's tripping. Therefore, it is necessary to refrain from the inclination of the tip height in the end, and there is no effect when there are individual differences in the footwear where the toes are lifted or how the passengers feel.

  On the other hand, in Patent Literature 2, when a passenger's toe gets on the protruding portion of the riser portion of the step on the pre-travel side when the horizontal portion approaches the intermediate inclined portion, it is prevented from being caught in the riser portion of the pre-travel side step. it can. However, the shape of the projecting part is a shape (R shape) that matches the driving posture of the intermediate inclined part and the horizontal part of the step (R shape), and if actually implemented, there is a gap between the projecting part and the step step part on the rear side of the run. Some kind of countermeasure will be necessary to prevent it from occurring.

  The present invention has been made in view of the above, and an object of the present invention is to provide an escalator capable of making it difficult for a passenger's toe to be sandwiched between a cleat and a riser.

  In order to achieve the above-described object, the present invention provides an escalator in which a number of steps move in a stepwise manner and the stepping plate of the step is flat in the vicinity of the entrance / exit, in the traveling direction front portion of the stepping plate of the step.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts.

Embodiment 1 FIG.
As shown in FIG. 1, the escalator 10 includes a metal truss 12, a handrail portion 14 provided on the truss 12, and a number of steps 31 inside the truss. Endless chains 18 are attached to both ends. A sprocket 16 for driving the chain 18 is arranged at the upper part of the escalator, and the sprocket 16 is rotated by a drive motor. The chain is fed up and down by the rotation of the sprocket 16 so that each step 31 has an intermediate inclined portion. Then, moving up and down repeatedly while making a staircase, passengers are transported from the lower floor to the upper floor and from the upper floor to the lower floor. Each step 31 shifts from a step-like shape at the middle inclined portion to a flat shape where the front and rear steps 31 have the same height as the approaching entrances of the upper floor and the lower floor are approached, so that the steps are eliminated. ing.

  As shown in FIG. 2, the step 31 includes a step board 33 on which a passenger stands and rides, and a riser 21 connected to the lower part from the left end (in the drawing) of the step board 33, and the riser 21 is generally loose. It is formed in a curved surface that is curved. This is because the movable track at the tip of the rear step 31 becomes a curved track when the step 31 before and after the entrance / exit changes from a flat state to a stepped shape in the middle inclined portion. Has a curved shape to match it.

  The tread board 33 and the riser 21 are fixed by a metal frame 35 inside thereof. The frame 35 is supported by a guide rail (not shown), and a guide roller 22 for smoothly moving the step 31 is rotatably supported. The guide roller 22 is moved up and down along the guide rail (not shown) by the driving chain 18 so that the step 31 of the escalator is its landing, and the adjacent step 31 is flat in the middle when getting off. In the inclined part, it becomes stepped and moves around.

  A recessed portion 32 is formed on the opposite side of the riser 21 in the depth direction of the tread plate 33 (front portion in the traveling direction during upward movement). Referring mainly to FIGS. 2 to 4, the recessed portion 32 extends to a state where some clearance is provided to the riser 21 of the front step 31 that travels, and the movable plate 23 extends from the upper surface of the step plate 33. The bottom surface of the recess 32 is formed in a state parallel to the surface of the tread plate 33.

  Further, the connection between the steps of the tread plate 33 and the recessed portion 32 is connected in a shape having a certain step. A movable plate 23 provided with a plurality of bearing portions 25 for allowing one end to rotate freely is mounted on the recess portion 32 so as to be placed on the recess portion 32, and the bearing portion 25 of the movable plate 23 and a pin, Or it installs so that it may become the same plane as the upper surface of the tread board 33 on the recessed part 32 in the state fixed with bearingable components, such as a screw | thread.

  This will be described with reference to FIGS. A plurality of support plates 24 for inclining and positioning the movable plate 23 are provided at the lowermost stage of the riser 21 of the front step 31 that travels, in other words, at the rear in the traveling direction when the step 31 moves upward. In the intermediate inclined portion where the movable plate 23 has a stepped shape, the movable plate 23 is lifted by the support plate 24, and the movable plate 23 is lifted up to a certain inclination angle, supported by the support plate 24 and stopped. With respect to this lifting angle, the inclination angle of the movable plate 23 can be changed by changing the height of the support plate 24.

  As a measure for preventing the movable plate 23 from being lifted from the stop position of the support plate 24 that supports the position of the movable plate 23 when the movable plate 23 is lifted, the end 23a on the rotation support portion side of the movable plate 23 is used as a tread plate. It can prevent raising from the stop position of the support plate 24 by making it contact 33 upward surface 33a. For this reason, when the steps 31 arranged in the front-rear direction shift from the horizontal portion to the intermediate inclined portion, they are lifted by a plurality of support plates 24 provided at the lowest stage of the riser 21 of the step 31 on the front side in the traveling direction of the steps 31 arranged in the front-rear direction. The movable plate 23 is rotated up to a predetermined angle with the rotation support portion as a starting point, and is movable even if it is lifted from the support position of the support plate 24 due to vibration during upward movement and downward movement by the chain 18. The plate 23 cannot be lifted any further by bringing the end portion 23a on the rotation support portion side into contact with the upward surface 33a of the tread plate 33. When changing the height of the support plate 24 and changing the tilt angle of the movable plate, it is possible to change the tilt angle at which the end 23a on the rotation support portion side of the movable plate 23 is brought into contact with the upward surface 33a of the tread plate 33. It becomes.

  As the movable plate 23 approaches the entrances of the upper floor and the lower floor, the front and rear steps 31 become flat, and accordingly, the support plate 24 provided at the lowest step of the riser 21 of the front step 31 is a rear step. Since the support plate 24 is not supported by moving away from the movable plate 23, the same height and the same flat state as the step plate 33 are stored, and the same height and the same plane as the step plate 33 are stored. This is because the movable plate 23 has a certain weight or more so that the opposite end of the rotating shaft descends to the upper surface of the recess 32 and stops with the weight as a starting point. It is.

  In order to make the movable plate 23 rotatable, a bearing portion 25 that supports rotation is formed immediately below the butted portion of the step plate 33 and the recessed portion 32 of the step 31. The bearing portion 25 is formed at a position slightly spaced from the flat plate-side end surface of the movable plate 23 on which the movable plate 23 is placed. When the position of the bearing portion 25 is set at a little distance from the plane (indicated by reference symbol a in FIG. 9) and a certain level difference is provided between the tread plate 33 and the recessed portion 32, the front side of the chain 18 moves upward. In the process in which the movable plate 23 is lifted and supported by the plurality of support plates 24 provided at the lowermost stage of the riser 21 of the step 31, the rotational trajectory of the movable plate 23 does not contact the inclined portion of the step plate 33 behind it. It can be a rotating orbit. In this step 31, a hole for passing the bearing portion 25 of the movable plate 23 is formed in the rotation support portion 26 provided immediately below the tread surface of the step plate 33, and the bearing portion 25 of the movable plate 23 is passed through this through hole. The movable plate 23 can be freely rotated by being fixed to the rotation support portion 31 of the bearing 31 by a rotatable bearing part such as a pin or a screw.

  The material of the movable plate 23 is preferably made of a resin similar to a cleat of a general escalator, and the color of the movable plate 23 is a warning color, for example, a yellow resin or a colored resin, so that the passengers are careful. It is possible to effectively show the arousal, and as a result, it is possible to urge not to stand or ride on this part. In addition, the movable plate 23 having the alert color moves to increase the appeal to the passengers and further alert.

  In FIG. 10, the upper surface of the movable plate 23 is formed in the shape of comb-like irregularities, like the conventional cleat surface, and the positions of the comb-like irregularities and the irregular surface on the upper surface of the tread plate 33 are aligned. It becomes the composition. A large number of grooves 44a called cleats are formed on the surface of the tread plate 33 in a shape that is aligned in the width direction and connected in the depth direction. Therefore, the ridges 44b are formed between the cleats, and are similarly formed in a shape connected in the depth direction. The comb-shaped irregularities are provided so that passengers standing on the comb teeth can get on and off the escalator without slipping.

  FIG. 11 shows the abutting surface between the tread plate 33 and the movable plate 23. In the movable plate 23, comb-like grooves 45 a and ridges 45 b corresponding to cleats formed on the upper surface of the tread 33 are formed on the upper surface, but the groove 45 a of the movable plate 23 is a groove 44 a of the tread 33. The groove 45a of the movable plate 23 and the groove 44a of the tread plate 33 are attached so as to be aligned in the width direction, that is, arranged so as to have the same width. For this reason, the protrusion 44b provided on the tread 33 at the abutting portion and the protrusion 45b having the same width provided on the movable plate 23 are half the width in the thickness direction (the width of the main protrusion other than the abutting portion). In a flat state in which the movable plate 23 is not supported by the support plate 24 by being divided and overlapped by half, that is, by 1/2, the gap in the depth direction of the protrusion 44b of the tread plate 33 and the protrusion 45b of the movable plate 23 Does not occur, and the width thereof can be the same as the width of the normal protrusion 44b of the tread 33. In addition, it is possible to pass without contacting the comb teeth when the step 31 passes through the comb teeth that are attached in accordance with the cleat shape of the step 31 at the entrances on the upper floor and the lower floor. it can. In addition, by overlapping the protrusions of the tread plate 33 and the movable plate 23 and eliminating gaps and dents in the depth direction, the passenger's feet do not get caught in the gap, do not sink, and there is no sense of incongruity. Even when the movable plate 23 is movable, there is no gap or dent in the depth direction of the projection 44b of the tread plate and the abutting portion of the movable plate 23, so that the movable plate 23 travels in the middle inclined portion. Even when supported by the support plate 24 of the riser 21 of the step 31 and lifted, it is possible to prevent passenger clothes, shoelaces and the like from being caught between the movable plate 23 and the step plate 33. Moreover, since it overlaps also in the width direction, there is no gap and it is possible to suppress the foreign matter from being caught between the butted surfaces of the tread plate 33 and the movable plate 23.

  As shown in FIG. 12, the overlapping portion of the protrusion 44b of the step plate 33 and the protrusion 45b formed on the movable plate 23 is symmetrical in the left and right with respect to the center C in the step width direction. Thus, the movable plate 23 can be positioned in the width direction, and lateral displacement during use can be suppressed. As a result, when the step 31 and the movable plate 23 are assembled, there is no need for positioning adjustment and the assembly is simplified.

  Further, as shown in FIGS. 13 and 14, even when the overlapping direction of the protrusion 44b of the tread 33 and the protrusion 45b formed on the movable plate 23 are all the same direction, the lateral displacement and the lateral alignment are formed immediately below the tread. The position is adjusted by adjusting the clearance between the bearing portion 25 of the movable plate and the rotation support portion 26 of the step. At that time, the shim 27 is inserted into the gap between the bearing portion 25 and the rotation support portion 26 to adjust the position. Even when the overlapping portion of the protrusion 44b of the step plate 33 and the protrusion 45b formed on the movable plate 23 is symmetric with respect to the center in the step width direction, the rotation of the bearing portion 25 of the movable plate and the step is performed. Shim adjustment to the gap with the support 26 is beneficial or necessary as appropriate.

  As shown in FIG. 15, a through hole for passing the bearing portion 25 of the movable plate 23 through the rotation support portion 26 directly below the tread plate 33 is formed on the upper surface of the recess portion 32 to which the movable plate 23 is attached. 46 is provided. In addition, a support plate 24 provided at the lowermost stage of the riser 21 of the step 31 for lifting the movable plate 23 of the step 31 that travels behind at a stepwise intermediate inclined portion is a slit 48 through which the recessed portion 32 passes. Is also provided at the tip of the recess 32 of the step 31.

  As shown in FIG. 16, the movable plate 23 and the step 31 are fixed rotatably. A drill hole is made in the bearing portion 25 of the movable plate 23, and a screw machining is given to the bearing portion of the step 31. Rotation in which the bearing portion 25 of the movable plate 23 is inserted into a through hole for passing the bearing portion 25 of the movable plate 23 through the rotation support portion 26 directly below the tread plate 33, and a hole provided in the tip of the bearing portion 25 is provided in the step 31. The position is aligned with the screw hole of the support portion 26 and fixed with the screw 28. The screw to be fixed is not a general screw but a screw with a stepped portion 28 having a screw portion 28a and a bearing portion 28b as shown in FIG. 17, and only the screw is fixed. A gap can be provided by the difference in the length of the bearing portion, and the movable plate 23 can be rotated freely. The through hole made in the bearing portion 25 of the movable plate 23 and the screw machining given to the rotation support portion 26 of the step 31 are the reverse processing, that is, the screw hole processing in the bearing portion 25 of the movable plate 23 and the rotation support portion 26 of the step 31 The same effect can be obtained by drilling holes.

  According to the escalator described above, even if the toes of the passengers on the steps of the escalator at the lower stage are in contact with the cleat part of the riser surface of the adjacent step on the front side of the run, the horizontal part where the passengers descend from the intermediate inclined part In the process of moving to, the passenger's toes can be made difficult to get caught between the cleat and the riser.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described. The second embodiment is the same as the first embodiment described above except for the parts described below.

  In the first embodiment, the bearing portion 25 of the movable plate 23 is made of resin. In the operation of the escalator that always repeats upward movement and downward movement, the bearing portion 25 of the movable plate 23 always repeats opening and closing. For this reason, it is conceivable that the resin hinge part is inferior in wear resistance and durability between the metallic step 31 and the resin hinge part.

  The movable plate 123 as the first example shown in FIG. 19 has a movable plate body made of a conventional resin product, and a bearing portion 25, that is, a portion extending from the body (plate-like portion) to the step 31 is made of metal. Thus, the wear resistance and durability of the bearing portion 25 can be improved and the life can be extended. In the first example, the metal bearing portion 25 and the resin main body are integrally formed. That is, when the resin movable plate 123 is molded as a molded product, the metallic bearing portion 25 is simultaneously molded and integrated with the resin movable plate 123.

  20 to 24 show a second example. In the second example of the separation type as compared with the first example of the resin integrated type, the metal bearing portion 25 is coupled to the resin movable plate 123. 20 and 21 show a fixing method using a plurality of screws. A bearing portion mounting portion 42 is formed on the back surface of the resin movable plate 123, and the bearing portion 25 is fixed with screws.

  As another separation type embodiment, as shown in FIG. 22 and FIG. 23, the fixed position is formed with a protrusion on the bearing portion mounting portion 42 of the movable plate 123, and the bearing portion is aligned with the protrusion. Positioning can be performed by forming a hole. In the embodiment described in FIG. 22 and FIG. 23 as the rotation support part mounting method, the number of protrusions is set to 2 or more, or a guide is provided on one side of the protrusion, and the rotation can be prevented and positioned. The number of screws can be fixed as one.

  Still another separation mode is a slit method as shown in FIGS. In FIG. 24, a slit for setting a metal bearing portion 25 made of a metal plate (rotation support portion) 34 is formed on the resin movable plate 123, and a metal bearing portion 25 having the same shape as the slit width is formed. To do. By inserting the bearing portion 25 into the slit, the inclination is regulated, and by preventing the rotation by the slit, positioning and fixing are performed with a single screw. In FIG. 25, when the resin movable plate 123 and the metal bearing portion 25 are fixed as a position fixing method that does not use screws, a slit and a hook-shaped protrusion 37 for positioning are provided on the resin movable plate 123. By providing a recess in the metal bearing portion 25, the metal bearing portion 25 is locked by the hook-shaped protrusion 37 just by inserting the metal bearing portion 25 into the resin slit of the movable plate 123, and the position is fixed. And will prevent it from coming off.

Embodiment 3 FIG.
Next, a third embodiment of the present invention will be described. In addition, this Embodiment 3 shall be the same as that of Embodiment 1 mentioned above except the part demonstrated below.

  In the first embodiment, when the movable plate 23 is lifted, the end on the rotating shaft side of the movable plate 23 is brought into contact with the tread plate 33 as a preventive measure for preventing the movable plate 23 from rotating further. As an alternative method, in the third embodiment, as a first example, as shown in FIGS. 26 and 27, a stopper 38 whose tip is shaped like an arrow is formed on the back surface of the movable plate 23 during resin molding of the movable plate. Molded by integral molding. When attaching the movable plate 23 to the step 31, an arrow-like stopper is inserted into the corresponding hole. After the inserted stopper has passed through the hole, the rising angle of the movable plate 23 can be regulated by the arrow-shaped fin at the front end being caught on the back surface of the hole with respect to the pulling direction. By positioning the rising height of the support plate 24, which is provided at the lowermost stage of the riser 21 of the front step 31 and tilts the movable plate 23, positioning at a required height can be performed, and the angle can be increased beyond that. Can be prevented. The tip of the arrow-shaped stopper attached to the movable plate 23 by integral molding has the same effect as a single arrow (letter shape), and the shape of the stopper is ideally the same as the R-shape of the radius of rotation by the hinge of the movable plate 23. The shape is smooth and the movement is smooth.

  As a second example, as shown in FIG. 28 and FIG. 29, as a separate part, an extensible part 40 such as a spring or rubber is fixed at both ends to the back surface of the movable plate 23 and the mounting surface of the movable plate 23 of the tread plate 33. May be. FIG. 28 shows an embodiment using springs, and FIG. 29 shows an embodiment using rubber. As a result, the movable plate 23 lifted by the support plate 24 provided at the lowermost stage of the riser 21 of the front step 31 in the intermediate inclined portion approaches the entrance / exit, and is supported when the adjacent step 31 approaches a flat shape. When the plate 24 moves away from the movable plate 23, it can return to a position parallel to the tread plate 33 by the force of a spring and rubber attached to the movable plate 23.

Embodiment 4 FIG.
Next, a fourth embodiment of the present invention will be described. In addition, this Embodiment 4 shall be the same as that of Embodiment 1 mentioned above except the part demonstrated below.

  In the first embodiment, the bearing portion 25 is provided on the movable plate 23 as the rotation starting point of the movable plate 23. However, the fourth embodiment replaces the shaft support structure of the first embodiment and has spring performance. The effect similar to that of the bearing portion 25 can be obtained by connecting the tread plate 33 and the movable plate 23 by the spring member 41 such as resin, rubber, or metal plate. In this case, the movable plate 23 lifted by the support plate 24 provided at the lowermost stage of the riser 21 of the front step 31 at the intermediate inclined portion approaches the entrance / exit, and is supported when the adjacent steps 31 approach a flat surface. Although the plate 24 moves away from the movable plate 23, a rubber having spring performance or a force to return to the original position of the metal plate works, so that the rubber having spring performance is separated from the support plate 24. Or it can return to a position with the force of a metal plate.

  Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.
