Description

  The present invention relates to a passenger conveyor such as an escalator or a moving sidewalk.

  FIG. 4 shows the structure near the exit when a conventional passenger conveyor is viewed from the inside. In the passenger conveyor 100, a railing 2 is erected on both sides of a moving body (not shown) such as a step, and a handrail 3 (moving handrail) is provided on the periphery of the railing 2. The handrail 3 enters the balustrade base 4 near the exit. The passenger conveyor 100 is provided with an inlet safety device that suddenly stops the conveyor operation when the hand of an infant is drawn toward the balustrade base 4 by the handrail 3 (see, for example, Patent Document 1). The inlet safety device includes a rubber safety device 5 protruding from the balustrade base 4 so as to surround the handrail 3, a limit switch (not shown) provided inside the balustrade base 4, and the like. When the safety device 5 is pushed in the moving direction M (arrow direction) of the handrail 3 by the hand, it is displaced in that direction. The displacement is detected by the limit switch, and the passenger conveyor 100 stops.

  In the vicinity of the exit of the passenger conveyor 100, passenger baggage or the like may collide with the safety device 5 from inside the passenger conveyor 100, that is, from the moving body side. At this time, as shown in FIG. 5, the safety device 5 is subjected to an external force f, is elastically deformed, is pressed against the handrail 3, and is displaced in the moving direction of the handrail 3. For this reason, although it is not the situation where a person's hand is drawn, a safety device operates and passenger conveyor 100 stops suddenly. Such an unnecessary sudden stop of the passenger conveyor 100 causes a risk of the passenger falling. Moreover, in order to restart the passenger conveyor 100 which stopped, operation by a maintenance worker is required and the inconvenience which cannot use the passenger conveyor 100 arises until the maintenance worker operates.

  In order to prevent a passenger's baggage from colliding with a safety device, a passenger conveyor is known in which a blocking body is erected in the vicinity of the safety device (see, for example, Patent Document 2). However, since the blocking body is erected on the floor surface, the installation is complicated.

  In addition, a passenger conveyor is known in which a guard plate that covers the safety device is provided on the balustrade base in order to prevent the stroller or the like from colliding with the safety device (see, for example, Patent Document 3). However, since this guard plate is provided on the outer side of the passenger conveyor, that is, on the side opposite to the moving body, it cannot prevent the passenger's baggage or the like from colliding from the inner side of the passenger conveyor.

BB sectional drawing of FIG.

  A passenger conveyor according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 1 and 2, the passenger conveyor 1 includes an endlessly connected moving body (not shown), a side skirt guard 41 serving as a side wall of the moving body, and a side skirt guard 41. An end skirt guard 42, a balustrade 2, a handrail 3 that moves around the periphery of the balustrade 2, a safety device 5 that is disposed at the entrance / exit of the handrail 3, and the like. The balustrade 2 has an inner deck cover 7 made of a decorative material. The passenger conveyor 1 has a handrail entrance / exit protection device 6 (hereinafter referred to as a protection device). The protection device 6 extends from the moving body side surface 43 of the end skirt guard 42 so as to cover the side of the safety device 5.

  The passenger conveyor 1 is an escalator or a moving sidewalk (moving sidewalk). The balustrade 2 is erected on both sides of a moving body composed of a plurality of steps in the passenger conveyor 1. The moving body may have an endless track shape. The side skirt guard 41, the end skirt guard 42, and the inner deck cover 7 are fixed to a structure (not shown) of the balustrade base 4, respectively. The handrail 3 moves at the same speed as the moving body and enters the balustrade base 4 near the exit of the passenger conveyor 1. A cylindrical safety device 5 protrudes from the handrail entrance / exit where the handrail 3 enters the balustrade base 4 so as to surround the handrail 3. The safety device 5 is made of rubber, for example, and its protrusion amount is about 50 to 100 mm, and is provided so as to be displaceable in the moving direction M of the handrail 3. A limit switch (not shown) for detecting the displacement of the safety device 5 is provided inside the balustrade base 4.

  An inlet safety device is constituted by the safety device 5 and the limit switch. When a human hand is pulled toward the balustrade base 4 by the handrail 3, the safety device 5 is pushed by the pulled hand and is displaced in the moving direction M of the handrail 3. The displacement of the safety device 5 is detected by the limit switch, and the passenger conveyor 1 suddenly stops the conveyor operation, that is, suddenly stops the movement of the moving body and the handrail 3.

  The protection device 6 is formed by molding a metal plate, for example, and is provided to prevent a passenger's baggage from colliding with the safety device 5 from the inside of the passenger conveyor 1. In the front view from the exit of the passenger conveyor 1, the safety device 5 and the protection device 6 are separated. In the side view, the protection device 6 extends from the moving body side surface 43 of the end skirt guard 42 in the direction in which the passenger descends, that is, in the direction opposite to the moving direction M of the handrail 3 and forms substantially the same plane as the side surface 43. To do.

  For example, the protection device 6 is separate from the end skirt guard 42, and is configured to fix the protection piece 61 on the side of the safety device 5 and the protection piece 61 to the end skirt guard 42. Fixed pieces 63 and 64.

  The protection device 6 may be configured integrally with the end skirt guard 42 with a protection piece 61 that covers the side of the safety device 5. In this case, the protection piece 61 is configured by projecting a part of the moving body side surface 43 of the end skirt guard 42.

  In the present embodiment, the protective device 6 is screwed to the existing screw hole of the end skirt guard 42, so that the protective device 6 is not provided on the passenger conveyor that does not have the protective device 6 without providing a new screw hole or the like. Added. As shown in FIG. 3, the protection device 6 includes fixing pieces 63 and 64 mainly composed of a protection piece 61 and made of a long plate-like member. The fixed piece 63 extends from the upper part of the protective piece 61 in the same plane. The fixed piece 64 extends orthogonally from the lower part of the protective piece 61. The fixing pieces 63 and 64 have screw holes 65 and 66, respectively. The protection device 6 formed in this way is attached to the protruding corner of the end skirt guard 42 on the moving body side. With the protection device 6 attached to the end skirt guard 42, the screw hole 65 is in a position corresponding to an existing screw hole for attaching the inner deck cover 7 to the end skirt guard 42, and the screw hole 66 is In the position corresponding to the existing screw hole of the front plate 42a of the skirt guard 42. The fixed piece 63 is sandwiched between the end skirt guard 42 and the inner deck cover 7, and is fixed together with the end skirt guard 42 and the inner deck cover 7 by screws that pass through the screw holes 65. The fixing piece 63 is in close contact with the front surface of the end skirt guard 42 and is screwed to the front plate 42 a of the end skirt guard 42 by a screw passing through the screw hole 66. Further, the protection device 6 has an abutting portion 67 that abuts on the lower side of the inner deck cover 7 from the inside, and is supported by the fixing pieces 63 and 64 and the abutting portion 67 at three points. The contact part 67 may be omitted.

  In a state where the protection device 6 is fixed to the end skirt guard 42, the upper portion 62 of the protection device 6 is accommodated in the lower portion of the inner deck cover 7. The upper part 62 of the protection piece 61 is bent about 15 degrees in the outward direction of the passenger conveyor 1 in order to avoid interference with the inner deck cover 7.

  The edge 61a of the protective piece 61 is preferably chamfered at the corner. Further, a cylindrical buffer member may be provided along the edge 61a, and the protective piece 61 may be bent toward the safety device 5 at the edge 61a to form a smooth convex curved surface. Thereby, the contact of the hand with the protective piece 61 is eased.

  The protection device 6 covers the side of the safety device 5 on the moving body side. When the safety device 5 is not displaced, the safety device 5 is exposed for a predetermined length L from the protection device 6 in the direction opposite to the moving direction M of the handrail 3 (see FIG. 1). The conveyor of the passenger conveyor 1 stops suddenly when the safety device 5 is displaced by a predetermined length L in the moving direction M of the handrail 3. The predetermined length L is slightly smaller than the total length of the safety device 5, and even if the safety device 5 is exposed for the predetermined length L, the blocking function by the protection device 6 is not impaired. Alternatively, the predetermined length L may be set to 0 or less so that the protective device completely covers the side of the safety device 5.

  The edge 61 a of the protection piece 61 is formed obliquely downward with respect to the moving direction M of the handrail 3 below the handrail 3. That is, the edge 61a is formed so as to approach the front plate 42a of the end skirt guard 42 obliquely downward. The inclination of the edge 61a is not limited to a constant value. In the present embodiment, the edge 61a has an arc shape and the lower portion of the protective piece 61 has a fan shape. The protective piece 61 is separated from the floor surface F.

  In the passenger conveyor 1 configured as described above, the passenger moves on a moving body of the passenger conveyor 1. In the vicinity of the exit of the passenger conveyor 1, passenger baggage or the like may approach the safety device 5 from the inside of the passenger conveyor 1. At that time, since the collision of the passenger's baggage or the like with the safety device 5 is blocked by the protection device 6, an unnecessary sudden stop of the passenger conveyor 1 is prevented. By preventing unnecessary sudden stops, the risk of a passenger falling is reduced.

  Since the protection device 6 is separate from the end skirt guard 42, the protection device 6 can be easily replaced when it is damaged by a collision of a foreign object or the like. Moreover, the fixing pieces 63 and 64 can be easily added to the existing passenger conveyor by forming the fixing pieces 63 and 64 into the existing screw holes of the end skirt guard 42 so that they can be screwed. For this reason, the cost which provides the protection apparatus 6 in the existing passenger conveyor is reduced.

  Further, when the protective piece 61 of the protective device 6 is configured integrally with the end skirt guard 42, the fixing pieces 63 and 64 for fixing the protective piece 61 are not necessary, and the protective device 6 is installed in a newly installed passenger conveyor. Can be provided at cost.

  Further, when the hand of a person hits the edge 61a of the protective device 6, the safety of the passenger conveyor 1 is improved because the hand is guided downward away from the handrail 3 by the inclination of the edge 61a.

  In addition, this invention is not restricted to the structure of said embodiment, A various deformation | transformation is possible in the range which does not change the summary of invention. For example, the protection device 6 is free to change its shape to prevent the intrusion of the hand or increase its strength. Further, the protective device 6 is not limited to a metal such as a stainless steel material or a painted steel material, and may be a molded synthetic resin material.
