Description

[Technical field]

[0001] The present invention relates to an upward escalator that transports passengers to upper floors by means of an endless transport body that moves in a circulating manner. [Background technology]

[0002] An escalator is equipped with a conveying section that conveys passengers by an endless conveying body consisting of multiple steps that are connected endlessly and move cyclically along a passageway, and a balustrade that is arranged along the passageway beside the endless conveying body and supports a handrail so that it can move cyclically. Passengers move from the entrance to the starting end of the endless conveying body (passenger receiving section) and when they board the endless conveying body, they are transported by the endless conveying body, and then when they reach the end of the endless conveying body (passenger sending-out section), they move to the exit and continue moving to leave the escalator.

[0003] However, there is a small gap of only a few millimeters between the aisle side surface of the lower part of the balustrade (the surface of the skirt guard) and the side edge of the steps. For this reason, in an upward escalator that transports passengers to higher floors, cases can occur in which clothing, shoes, sandals and other footwear or small items (hereinafter collectively referred to as "objects") get caught in this gap when passengers board the endless conveyor or while being transported by the endless conveyor. This is thought to be caused by the fact that the aisle side surface of the lower part of the balustrade moves diagonally downward relative to the side edge of the steps, causing the object to be dragged by the aisle side surface of the lower part of the balustrade and pulled into the gap.

[0004] As a countermeasure to this, Patent Document 1 describes applying a lubricant to the surface of the skirt guard. As another countermeasure, Patent Document 2 describes forming a plurality of projections and recesses on the surface of the skirt guard. As yet another countermeasure, Patent Document 3 describes forming a plurality of ridges extending along the moving direction on the surface of the skirt guard in an array in a direction perpendicular to the moving direction.

[0006] However, these measures are not designed to actively remove objects that are caught or are about to be caught in the gap, and therefore have the problem of being insufficient as a structure to prevent objects from being caught.

[0007] Therefore, the present invention has been made in consideration of such circumstances, and has an objective of providing an escalator that can effectively prevent objects from getting caught in the gap between the aisle-side surface of the lower part of the balustrade and the side edge of the steps. [Means for solving the problem]

[0008] The escalator according to the present invention comprises: An upward escalator comprising: a conveying section that conveys passengers obliquely upward by an endless conveying body made up of a plurality of steps that are endlessly connected and move cyclically along a passage; and a balustrade that is disposed along the passage to the side of the endless conveying body and supports a handrail so as to be cyclically movable, The surface of the lower part of the balustrade facing the passageway is provided with multiple protruding ridges at a specified pitch in the direction of travel, which protrude so as not to come into contact with the side edge of the steps and which satisfy the following conditions (A) and (B). It's an escalator. (A) The convex portion is inclined at an angle greater than the angle of inclination of the direction of movement relative to the horizontal direction. (B) The lower side of the convex rib intersects with line Z1, and the upper side of the convex rib intersects with line Z2. Line Z1: A line that passes through the intersection with line Y1 on the surface and is parallel to the direction of movement (Line Y1: Intersection of a vertical plane passing through the leading edge of the adjacent step in the direction of movement of one step and the top surface of that step) Line Z2: A line that passes through the intersection with line Y2 on the surface and is parallel to the direction of movement (Line Y2: Intersection of the vertical plane passing through the base edge of the adjacent step on the opposite side to the direction of movement of the step and the top surface of the step)

[0009] Here, as one embodiment of the escalator according to the present invention, The convex portion further satisfies the following condition (C). (C) The pitch of the ridges in the direction of travel is 33% or more of the pitch of the steps in the direction of travel. The above configuration can be adopted.

[0010] In another aspect of the escalator according to the present invention, The convex portion further satisfies the following condition (D). (D) The pitch of the ridges in the direction of travel is 100% or less than 100% of the pitch of the steps in the direction of travel. The above configuration can be adopted.

[0011] In another aspect of the escalator according to the present invention, The convex portion further satisfies the following condition (E). (E) The distance between the horizontal convex stripes is 25 cm or less. The above configuration can be adopted.

[0012] In still another aspect of the escalator according to the present invention, The convex portion further satisfies the following condition (F). (F) The difference between the inclination angle of the convex ridge and the inclination angle of the moving direction is within the range of 30°±10°. The above configuration can be adopted. Effect of the Invention

[0013] According to the present invention, the convex rib portion applies a force to push an object upward through the gap between the aisle side surface of the lower part of the balustrade and the side edge of the step, and therefore, according to the present invention, it is possible to effectively prevent an object from being caught in the gap in the area where the convex rib portion is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The escalator according to this embodiment will be described below.

[0016] As shown in FIG. 1, escalator 1 comprises a truss (not shown), a boarding / alighting entrance 3, a conveying section 4, and a handrail section 5. The truss is a structure that supports the weight of escalator 1 and the load it is carrying. The boarding / alighting entrance 3 are provided at the top of both ends of the truss and are located at the ends (start end and end) of the aisle. The conveying section 4 is supported by the truss and has treads that move along the aisle, thereby conveying passengers while keeping them standing in that position without making them walk. The handrail sections 5 are also supported by the truss and are provided along the aisle on both sides.

[0017] The escalator 1 is an upward escalator that transports passengers from left to right (from a lower floor to an upper floor). In this case, the escalator 1 has, from left to right, an entrance, a transport section 4, and an exit. The upward and downward directions of the escalator 1 can be switched by changing the settings.

[0018] The boarding / alighting entrance 3 is provided at the top of the horizontal end of the truss. The boarding / alighting entrance 3 is equipped with a floor plate 30. The floor plate 30 forms the floor of the boarding / alighting entrance 3, and is installed at the end (start end, end) of the passage. The tip of the floor plate 30 defines the boundary between the boarding / alighting entrance 3 and the conveying section 4.

[0019] The conveying section 4 includes an endless conveying body 40. The endless conveying body 40 is formed by connecting a plurality of steps 41, ... in an endless manner via a step chain 43. The endless conveying body 40 is arranged in the truss so as to be able to circulate along the longitudinal direction of the truss. The endless conveying body 40 circulates in one direction or the opposite direction as the step chain 43 circulates in response to the driving of a drive motor (not shown) arranged in the truss.

[0020] As shown in FIG. 2(a), the step 41 includes a step board portion 410, a riser portion (vertical board portion) 411, and a yoke portion 412. The step board portion 410 is a plate-like member along a horizontal plane, and its upper surface (strictly speaking, the upper surface of the body of the step board portion 410 excluding the boundary display portion 413 described later) is the step surface. The upper surface of the step 41 on the forward path is kept horizontal in all of the horizontal portion 4A that contacts the boarding / alighting entrance 3 of the conveying section 4, the inclined portion 4C that is the main portion of the forward path, and the transition portion 4B between the horizontal portion 4A and the inclined portion 4C. The riser portion 411 is a plate-like member that hangs down from the tip of the step board portion 410 and extends downward while curving in an arc shape. The yoke portion 412 is a reinforcing member that connects the side edge of the step board portion 410 and the side edge of the riser portion 411. A pair of yoke portions 412 are provided on the left and right sides.

[0021] The step board section 410 includes a boundary display section 413. The boundary display section 413 is provided along three sides of the step board section 410, the left and right side edges and the base edge, and is colored a color (e.g., yellow) different from the color of the main body of the step board section 410, and is also called a demarcation line. The boundary display section 413a on the side edges of the step board section 410 is provided in a rectangular area of ​​a predetermined width with the side edge (outer edge) 410a of the step board section 410 as the long side, and indicates the boundary with the skirt guard 53 of the balustrade 51 described later. The boundary display section 413b on the base edge of the step board section 410 is provided in a rectangular area of ​​a predetermined width with the base edge (outer edge) 410b of the step board section 410 (excluding the part of the boundary display section 413a) as the long side, and indicates the boundary with the adjacent step 41 on the moving direction side. 2(b), the boundary display section 413 may be provided in a frame shape along the four sides of the left and right side edges, base edge, and tip end of the step section 410. In this case, the boundary display section 413c at the tip end of the step section 410 is provided in a rectangular area of ​​a predetermined width with the tip edge (outer edge) 410c (excluding the part of the boundary display section 413a) of the step section 410 as the long side, and indicates the boundary with the adjacent step 41 on the opposite side to the moving direction.

[0022] For example, the body of the step 410 is made of metal such as iron, stainless steel, or aluminum, and the boundary display 413 is made of hard resin. Also, for example, the depth of the step 41 (the distance between the leading edge 410c and the base edge 410b) is 40 cm, the width of the boundary display 413b is 3.42 cm, and the width of the boundary display 413c is 3.13 cm.

[0023] As shown in FIG. 3, the handrail section 5 includes a handrail 50 and a balustrade 51. The handrail 50 is also called a moving handrail and is flexible and endless. The handrail 50 moves in a circulating manner in conjunction with the endless transport body 40. The balustrade 51 is disposed on the side of the endless transport body 40 along the longitudinal direction of the endless transport body 40. The balustrade 51 has a lower side supported by the truss 2 and supports the handrail 50 so that it can move in a circulating manner. A pair of handrails 50 and balustrades 51 are provided on both sides of the passageway along the passageway.

[0024] The balustrade 51 includes a balustrade panel 52, a skirt guard 53, an exterior material 54, and a deck cover 55. The balustrade panel 52 is disposed vertically between the outward portion 50A, which is the upper edge portion of the handrail 50, and the return portion 50B, which is the lower edge portion, and faces the passage. The skirt guard 53 is disposed vertically downward from the height position of the lower edge portion of the balustrade panel 52, inside the balustrade panel 52, and faces the passage. The exterior material 54 is disposed vertically downward from the height position of the lower edge portion of the balustrade panel 52, outside the balustrade panel 52, and is disposed vertically with a predetermined distance from the skirt guard 53. The deck cover 55 is detachably attached so as to close the upper opening between the skirt guard 53 and the exterior material 54. In this way, the balustrade 51 has an internal space surrounded by the skirt guard 53, the exterior material 54, and the deck cover 55. The return portion 50B of the handrail 50 is housed in the internal space and is shielded from the outside. That is, the skirt guard 53, the exterior material 54 and the deck cover 55 form a shielding portion that shields the return portion 50B of the handrail 50.

[0025] Returning to FIG. 1, the skirt guard 53 includes a convex rib portion 530. The convex rib portion 530 is formed in a straight line. Alternatively, the convex rib portion 530 may be formed in a gently curved curve. The convex rib portion 530 is provided on the surface of the skirt guard 53 at a predetermined interval and at a predetermined pitch in the moving direction (advancement direction) of the conveying section 4 (endless conveying body 40 (steps 41)). More specifically, the convex rib portion 530 is provided on each of the horizontal portion 4A, the transition portion 4B, and the inclined portion 4C (at least a part or all of the inclined portion) on the boarding side of the conveying section 4, and is provided overall at a predetermined interval and at a predetermined pitch in the moving direction. In any of the horizontal portion 4A, the transition portion 4B, and the inclined portion 4C of the conveying section 4, the convex rib portion 530 is inclined at the same inclination angle with respect to the moving direction (horizontal direction in the case of the horizontal portion 4A, and diagonally upward in the case of the transition portion 4B and the inclined portion 4C).

[0026] 4(a), the convex ridge portion 530 is inclined at an inclination angle R2 that is greater than an inclination angle R1 of the moving direction P with respect to the horizontal direction. The convex ridge portion 530 is inclined so that its upper end is located on the moving direction P side of a vertical line passing through its lower end. As an example, the inclination angle R1 is 30°, the inclination angle R2 is 60°, and the difference in the inclination angles R2-R1 is 30°.

[0027] The convex rib portion 530 is provided so that its lower side intersects with line Z1 and its upper side intersects with line Z2. That is, the convex rib portion 530 is provided at least between line Z1 and line Z2. As an example, the convex rib portion 530 is provided so that its lower end (of the center line in the width direction) is located on line Z1 and its upper end (of the center line in the width direction) is located on line Z2. Lines Z1 and Z2 are defined as follows. Z1: A line that passes through the intersection with line Y1 on the surface of the skirt guard 53 and is parallel to the moving direction P (Y1: Intersection line between vertical plane X1 and the top surface of one step 41, X1: a vertical plane passing through the leading edge 410c of the adjacent step 41 on the moving direction P side of the step 41 in question) Z2: A line that passes through the intersection with line Y2 on the surface of the skirt guard 53 and is parallel to the moving direction P (Y2: Intersection line between the vertical plane X2 and the top surface of the step 41, X2: a vertical plane passing through the base edge 410b of the adjacent step 41 on the opposite side to the moving direction P of the step 41)

[0028] Alternatively, the convex rib portion 530 may be provided so that its lower side intersects with the line Z1' and its upper side intersects with the line Z2'. That is, the convex rib portion 530 may be provided at least between the lines Z1' and Z2'. As an example, the convex rib portion 530 may be provided so that its lower end (of the center line in the width direction) is located on the line Z1' and its upper end (of the center line in the width direction) is located on the line Z2'. The lines Z1' and Z2' are defined as follows. Z1': A line that passes through the intersection with the line Y1' on the surface of the skirt guard 53 and is parallel to the moving direction P. (Y1': inner edge line of the boundary indication portion 413b on the top surface of one step 41) Z2': A line that passes through the intersection with line Y2' on the surface of the skirt guard 53 and is parallel to the moving direction P (Y2': the inner edge of the boundary display portion 413c on the top surface of the step 41)

[0029] The convex rib portion 530 is provided so that the pitch in the moving direction P is 100% of the pitch Q of the steps 41 in the moving direction P. In other words, the convex rib portion 530 is provided so that the pitch in the moving direction P is the same as the pitch Q of the steps 41 in the moving direction P.

[0030] The ridges 530 are provided so that the distance S between the ridges 530, 530 in the horizontal direction is 25 cm or less. The value of 25 cm is based on the average foot size of an adult male, which is 25.5 cm (see, for example, the appendix to the "size-JPN 2004-2006" Survey Results, reported by the Ministry of Economy, Trade and Industry on October 1, 2007). By setting the distance S between the ridges 530, 530 in the horizontal direction to 25 cm or less, the footwear always straddles the two ridges 530, 530, one in front and one in back.

[0031] As shown in Fig. 4(b) and (c), the convex strip portion 530 is formed by pressing the metal plate of iron, stainless steel, or the like that constitutes the skirt guard 53. The convex strip portion 530 protrudes from the surface of the skirt guard 53 toward the step 41 with a protruding height T. The protruding height T is set to a level that the convex strip portion 530 does not come into contact with the side edge of the step 41 so as not to interfere with the step 41 and cause a hindrance to the circulatory movement of the endless conveyor 40. As an example, the gap between the surface of the skirt guard 53 and the side edge of the step 41 is 4 mm, the protruding height (protruding amount) T of the convex strip portion 530 is 3 mm, and the gap between the convex strip portion 530 and the side edge of the step 41 is 1 mm. This gap is preferably 2 mm or less, and more preferably 1.5 mm or less.

[0032] As shown in Fig. 4(c), the convex ridge portion 530 has upper and lower side portions. The angle U1 of the upper side portion (the side portion facing vertically upward) is 60° or more and 175° or less. As an example, the angle U1 of the upper side portion is 90°. The angle U2 of the lower side portion (the side portion facing vertically downward) is the same angle as the angle U1 of the upper side portion.

[0033] Alternatively, as shown in Fig. 4(d), the angle U2 of the lower side surface portion may be larger than the angle U1 of the upper side surface portion. Alternatively, as shown in Fig. 4(e), the lower side surface portion may be omitted, and an inclined surface portion may be provided that is inclined obliquely from the edge of the upper side surface portion toward the surface of the skirt guard 53. In the case of Fig. 4(d) and Fig. 4(e), the degree of engagement (the downward force as the reaction force) when approaching the convex rib portion 530 from below the convex rib portion 530 (an event that occurs when the setting of the escalator 1 is changed from up to down) is smaller than the degree of engagement (the upward force as the reaction force) when approaching the upper side surface portion of the convex rib portion 530 from above the convex rib portion 530.

[0034] The configuration of escalator 1 according to this embodiment is as described above. Next, the function of convex strip portion 530 will be described.

[0035] As shown in FIG. 5, when the relative positional relationship between the step 41 and the convex strip portion 530 is taken into consideration, the convex strip portion 530 moves from the base end to the tip end on the upper surface of the step 41 as the step 41 moves. At this time, when a passenger stands on either the left or right end of the step 41 and the outer side of the footwear is in contact with or close to the surface of the skirt guard 53, the convex strip portion 530 contacts the outer side of the footwear while continuously moving the contact point from the tip of the footwear toward the heel side. Then, the convex strip portion 530 applies an upward force along the normal direction diagonally upward to the outer side of the footwear at the contact point by the obliquely inclined upper side portion. Therefore, while the footwear is in contact with the convex strip portion 530, the footwear receives an upward force, that is, a force that tries to push it upward from the gap between the surface of the skirt guard 53 and the side edge of the step 41.

[0036] Even if one ridge 530 tries to pass through the footwear, the next ridge 530 arrives and contacts the outer side of the footwear, and the same action is repeated. Therefore, the footwear continues to receive the force as long as it is in contact with or close to the surface of the skirt guard 53.

[0037] As described above, in the escalator 1 according to this embodiment, the convex stripe 530 is inclined at an inclination angle R2 that is greater than the inclination angle R1 of the moving direction P with respect to the horizontal direction. As a result, the convex stripe 530 applies a force that pushes the footwear upward through the gap between the surface of the skirt guard 53 and the side edge of the step 41. Therefore, in the escalator 1 according to this embodiment, it is possible to suitably prevent the footwear from being caught in the gap in the area where the convex stripe 530 is provided.

[0038] Furthermore, in the escalator 1 according to this embodiment, the convex strip portion 530 is inclined at an inclination angle R2 that is 30° greater than the inclination angle R1 of the moving direction P with respect to the horizontal direction. This 30° is a suitable value for halving the force that tries to pull the footwear into the gap between the surface of the skirt guard 53 and the side edge of the step 41. Therefore, the escalator 1 according to this embodiment can achieve a high pinch prevention effect.

[0039] Furthermore, with the escalator 1 according to this embodiment, when a force acts on footwear, passengers become concerned about this and try to avoid it by moving their feet away from the skirt guard 53 and trying to take a standing position closer to the center of the step 41, away from the skirt guard 53. Therefore, with the escalator 1 according to this embodiment, it is possible to avoid the risk of footwear getting caught in the gap.

[0040] Furthermore, according to the escalator 1 of this embodiment, the convex rib portion 530 is provided at least between the lines Z1 and Z2 (or at least between the lines Z1' and Z2'). This means that the convex rib portion 530 has a length that substantially covers the entire range from the base end to the tip end of the tread 41. Therefore, according to the escalator 1 of this embodiment, a high pinch prevention effect can be obtained.

[0041] Furthermore, according to the escalator 1 of this embodiment, the convex rib portion 530 is provided along the moving direction P at a pitch (the same pitch) that is 100% of the pitch Q of the steps 41 in the moving direction P. This, combined with the fact that the convex rib portion 530 is provided at least between lines Z1 and Z2 (or at least between lines Z1' and Z2'), means that the convex rib portion 530 is substantially continuous without seams in the range in which it is provided. Therefore, according to the escalator 1 of this embodiment, a high pinch prevention effect can be obtained.

[0042] Furthermore, according to the escalator 1 of this embodiment, the convex stripes 530 are provided along the moving direction P so that the distance S between the convex stripes 530, 530 in the horizontal direction is smaller than the average foot size of an adult male, which is 25.5 cm. This means that the footwear always straddles the two convex stripes 530, 530, one in front and one in back, so that the convex stripes 530 are substantially continuous without seams within the range in which the convex stripes 530 are provided. Therefore, according to the escalator 1 of this embodiment, a high pinch prevention effect can be obtained.

[0043] These effects are not limited to footwear, but can also be obtained for a variety of items such as skirts, trousers, and other clothing, and accessories.

[0044] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the gist of the present invention.

[0045] In the above embodiment, the convex rib portion 530 is inclined at an inclination angle R2 (60°) that is 30° larger than the inclination angle R1 (30°) of the moving direction P relative to the horizontal direction. However, the present invention is not limited to this. The inclination angle R2 may be any value, provided that the upper end of the convex rib portion 530 is located on the moving direction P side of the vertical line passing through the lower end of the convex rib portion 530 and the inclination angle R2 is larger than the inclination angle R1.

[0046] However, since the suitable value for halving the force that tries to pull the footwear into the gap between the surface of the skirt guard 53 and the side edge of the step 41 is the difference in inclination angles R2-R1=30°, the difference in inclination angles R2-R1 can be set with a lower limit of 20° (FIG. 6(a)) and an upper limit of 40° (FIG. 6(b)), that is, within the range of 30°±10° with 30° as the center. Note that, even in these cases, it is more preferable to set the distance S between the convex rib portions 530, 530 in the horizontal direction to 25 cm or less.

[0047] In the above embodiment, the convex rib portion 530 is provided so that the lower end is located on the line Z1 (or line Z1') and the upper end is located on the line Z2 (or line Z2'). However, the present invention is not limited to this. As shown in FIG. 7(a), the lower end of the convex rib portion 530 may extend beyond the line Z1 (or line Z1'), or the upper end of the convex rib portion 530 may extend beyond the line Z2 (or line Z2').

[0048] In the above embodiment, the convex ridge portion 530 is provided along the moving direction P at the same pitch as the pitch Q of the steps 41 in the moving direction P. That is, one convex ridge portion 530 is provided for one pitch of the steps 41. However, the present invention is not limited to this.
