Description

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

  Many passengers enter the escalator, which is a form of a passenger conveyor installed at stations and airports, along with luggage such as carry bags. The passenger on the escalator may release his / her hand after placing the luggage on the steps. Such luggage may fall down due to unstable placement or contact with other passengers, slipping down steps with rollover, and colliding with passengers located below, causing an accident that passengers may fall over. It can happen.

  In a passenger conveyor such as an escalator, there is a technique described in Patent Literature 1 as a technique for preventing a load on a step from falling down. Patent Literature 1 discloses a passenger conveyor including a stopper that can protrude from an upper surface of a step using a roller and a link and that can retreat from the protruding state for each step.

  Further, in Patent Literature 2, the material of the shock absorbing cleat provided at the corner of the step (step) of the escalator and its material characteristics are selected, and even if the passenger falls over and the head collides with the corner of the step. An escalator to prevent serious injury is disclosed.

The lower terminal sprocket 12 is supported in the lower machine room 11. The upper machine room 9 is provided in the upper horizontal frame 2a. The lower machine room 11 is provided in the lower horizontal frame 2b.

  In step 5, both sides in the width direction are connected to a pair of step chains 8. In step 5, when the step chain 8 is driven by a drive device (not shown), the step chain 8 circulates between the upper and lower floors 3 and 4. On the upper surface of step 5, passengers and luggage are placed.

  FIG. 2 is a perspective view showing a configuration example of step 5 of the escalator 1.

  Step 5 includes a cleat 21 on which a passenger rides, a riser 22 having an arc surface extending downward from a rear end (an end on the lower floor side) of the cleat 21, and a main body for joining the cleat 21 and the riser 22. And a frame 23. The cleat 21 includes a plurality of peaks and grooves parallel to the moving direction of the step 5, and the peaks and the grooves are alternately arranged in the width direction.

  FIG. 3 is an explanatory diagram showing a state in which the luggage placed in step 5 slides down on the escalator 1. In FIG. 3, the right side is the front direction, and the left side is the rear direction. FIG. 3 shows a state in which the load 27 placed in step 5a has slipped down to steps 5b and 5c located below step 5a. Part A in FIG. 3 is a corner where the rear end of the cleat 21 and the upper end of the riser 22 intersect in step S5.

  The escalator 1, which is a passenger conveyor, moves on an orbit where the step 5 is inclined. In particular, in the escalator 1 installed at a station or an airport, many passengers get on with the baggage 27 such as a carry bag, but after putting the baggage 27 on the step 5, many passengers release their hands from the baggage 27. . As shown in FIG. 3, the baggage 27 falls down due to unstable placement of the baggage 27 on the step 5 or contact of the baggage 27 placed on the step 5 with another passenger. Step 5 may slide down.

  The escalator 1, which is a passenger conveyor according to the present embodiment, has a simple structure and can suppress the sliding speed of the baggage 27 in step 5, and can prevent the slipped baggage 27 from colliding with a passenger located below, and can reduce the slipped baggage. Even if a passenger collides with 27, it is possible to prevent the passenger from being injured, so that the safety of the passenger can be improved.

  Hereinafter, the escalator 1 according to the present embodiment will be described with respect to a slip-down speed suppressing structure that is a structure that suppresses the slip-down speed of the load 27 in step 5. The sliding speed suppressing structure of the escalator 1 according to the present embodiment intersects with the riser 22 of the cleat 21 at the corner where the cleat 21 intersects the riser 22 at the rear end of the cleat 21, that is, the riser 22 of the rear demarcation 24. It is provided at the peak of the cleat 21 at the corner. The sliding speed suppressing structure is an uneven portion having fine unevenness, and has a larger coefficient of friction than the other portion of the upper surface of step 5.

  An escalator 1 which is a passenger conveyor according to a first embodiment of the present invention will be described.

  FIG. 4A is a diagram showing step 5 of the escalator 1 which is a passenger conveyor according to the first embodiment of the present invention, and is a cross-sectional view of a part A in FIG. FIG. 4B is a perspective view of Step 5 of the escalator 1 which is a passenger conveyor according to Embodiment 1 of the present invention.

  Step 5 includes a slip-down speed suppressing structure at the peak of the cleat 21 at the corner where the rear demarcation 24 intersects with the riser 22. The slip-down speed suppressing structure is provided on the upper surface 21a (the upper surface of step 5) of the peak of the cleat 21. Further, it is preferable to provide the slip-down speed suppressing structure on the rear surface 21b of the mountain portion of the cleat 21 because the effect of suppressing the slip-down speed of the load 27 is further increased.

  The slip-down speed suppressing structure is an uneven portion having fine unevenness 31 and slides on the load 27 when the load 27 slides down in step 5, and suppresses the slip-down speed of the load 27 by frictional resistance with the load 27. The shape and size of the irregularities are arbitrary, and the arrangement of the irregularities is also arbitrary (i.e., the irregularities of the irregularities), as long as the fine irregularities 31 can be slid into contact with the package 27 and the sliding speed of the package 27 can be suppressed by frictional resistance. The arrangement may be regular or irregular).

  The sliding speed suppressing structure of Step 5 has a larger coefficient of friction than the portion without the sliding speed suppressing structure on the upper surface of Step 5 (the upper surface 21a of the mountain portion of the cleat 21) due to the fine unevenness 31.

  Although FIG. 4B shows a configuration in which the fine unevenness 31 is provided on the crests of the four cleats 21, the fine unevenness 31 is preferably provided on the crests of all the cleats 21.

  The fine unevenness 31 is formed by, for example, processing the surface of the rear demarcation 24 by an arbitrary method to provide a fine uneven shape, or applying a paint mixed with silica sand or the like to the surface of the rear demarcation 24. Thereby, it can be provided at the peak of the cleat 21. When the rear demarcation 24 is made of a resin, fine irregularities 31 can be provided on the crests of the cleat 21 by mixing glass fiber or the like with the resin at the time of forming the rear demarcation 24. . That is, the fine irregularities 31 serving as the sliding speed suppressing structure can be formed by processing the surface of the rear demarcation 24, glass fibers mixed with resin, silica sand mixed with paint, and the like.

  When the baggage 27 placed in step 5 falls down and slides down, in many cases, the side surface of the baggage 27 lying down abuts on the corner at the rear end of step 5. Then, the fine unevenness 31 of the rear demarcation 24 slides on the side surface of the load 27 and suppresses the sliding speed of the load 27 by frictional resistance.

  In the escalator 1 according to the present embodiment, since the rear demarcation 24 has the fine irregularities 31 as the slip-down speed suppressing structure, the slip-down speed of the load 27 is suppressed by frictional resistance, and the passenger whose slip-down load 27 is located below is Collision can be prevented, and even if the slipped baggage 27 collides with a passenger located below, the impact at the time of the collision can be reduced to prevent the passenger from being injured, thereby improving the safety of the passenger. . In addition, since the slide-down speed suppressing structure is a simple configuration including the fine irregularities 31 provided on the rear demarcation 24, the slide-down speed of the load 27 can be suppressed at low cost.

  Furthermore, if the rear demarcation 24 is made of a separate component from the cleat 21 and can be attached to and detached from the step 5, if the slip-down speed suppressing structure is provided on the existing escalator, It is only necessary to replace the side demarcation 24 with a rear side demarcation 24 having a sliding speed suppressing structure. As described above, the sliding speed suppressing structure can be easily installed on an existing escalator.

  An escalator 1 which is a passenger conveyor according to a second embodiment of the present invention will be described. Hereinafter, points different from the first embodiment will be mainly described.

  FIG. 5A is a diagram showing step 5 of the escalator 1 which is a passenger conveyor according to the second embodiment of the present invention, and is a cross-sectional view of a portion A in FIG. FIG. 5B is a perspective view of Step 5 of the escalator 1 which is a passenger conveyor according to Embodiment 2 of the present invention.

  The sliding speed suppressing structure is an uneven portion formed by fixing resin or metal particles 32 to the cleat 21 at the corner of the rear demarcation 24 where the riser 22 intersects. This uneven portion has fine unevenness composed of particles 32. Even if the baggage 27 placed in step 5 falls down and slides down, the particles 32 provided on the rear demarcation 24 slidably contact the baggage 27, and the sliding speed of the baggage 27 is suppressed by frictional resistance. As the resin particles 32, for example, acrylic particles can be used. As the metal particles 32, for example, aluminum particles can be used.

  The sliding speed suppressing structure of Step 5 has a larger friction coefficient due to the particles 32 than the portion without the sliding speed suppressing structure on the upper surface of Step 5 (the upper surface 21a of the peak portion of the cleat 21).

  Although FIG. 5B shows a configuration in which the particles 32 are provided on the peaks of the four cleats 21, the particles 32 are preferably provided on the peaks of all the cleats 21.

  When the particles 32 are made of resin, the resin particles 32 are welded to the rear demarcation 24 by thermal spraying or the like, or a paint mixed with the resin particles 32 is applied to the rear demarcation 24. Thus, the particles 32 can be fixed to the peaks of the cleat 21 to form fine irregularities.

  When the particles 32 are made of metal, the metal particles 32 may be welded to the rear demarcation 24 by thermal spraying or the like, so that the particles 32 are fixed to the peaks of the cleat 21 to form fine irregularities. it can. When the rear demarcation 24 is made of metal, the particles 32 are preferably made of metal.

  In the escalator 1 according to the present embodiment, the rear demarcation 24 has fine irregularities formed of the particles 32 as the sliding speed suppressing structure, so that the same effect as the escalator 1 according to the first embodiment can be obtained. That is, the escalator 1 according to the present embodiment can suppress the slipping speed of the luggage 27 due to the frictional resistance, prevent the slipped luggage 27 from colliding with the passenger located below, and reduce the luggage 27 located below the passenger. Even if a collision occurs, it is possible to prevent the passenger from being injured by weakening the impact at the time of the collision, thereby improving the safety of the passenger.

  An escalator 1 which is a passenger conveyor according to a third embodiment of the present invention will be described. Hereinafter, points different from the first and second embodiments will be mainly described.

  FIG. 6A is a diagram showing Step 5 of the escalator 1 which is a passenger conveyor according to Embodiment 3 of the present invention, and is a cross-sectional view of a portion A in FIG. FIG. 6B is a perspective view of Step 5 of the escalator 1 which is a passenger conveyor according to Embodiment 3 of the present invention.

  The escalator 1 according to the present embodiment has a surface 33 that is inclined with respect to the upper surface of the step 5 at a corner where the rear demarcation 24 intersects with the riser 22. The inclined surface 33 is a surface that is provided at the crest of the cleat 21 and serves as a chamfer of a corner that intersects the riser 22 of the rear demarcation 24. The inclined surface 33 is provided with an uneven portion which is a structure for suppressing a sliding speed at a mountain portion of the cleat 21. That is, the inclined surface 33 includes the fine irregularities 31 described in the first embodiment or the particles 32 described in the second embodiment. 6A and 6B show a configuration in which the inclined surface 33 includes the particles 32 as an example.

  The uneven portion (the fine unevenness 31 described in the first embodiment or the particle 32 described in the second embodiment) which is the sliding speed suppressing structure has not only the inclined surface 33 but also the upper surface 21a and the rear surface of the mountain portion of the cleat 21. 21b.

  FIG. 6B shows a configuration in which the particles 32 are provided on the inclined surfaces 33 of the peaks of the four cleats 21. However, the particles 32 are preferably provided on the inclined surfaces 33 of the peaks of all the cleats 21. preferable.

  The inclination angle α (FIG. 6A) of the inclined surface 33 with respect to the upper surface of the step 5 can be arbitrarily determined. However, the inclination angle α is preferably equal to the inclination angle of the escalator 1 (the angle connecting the lower floor and the upper floor). If the inclination angle α of the inclined surface 33 is equal to the inclination angle of the escalator 1, the load 27 placed in step 5 slides down at the inclination angle of the escalator 1 when it slides down, and comes into contact with the inclined surface 33, This is because the area in contact with the uneven portion (the fine unevenness 31 or the particles 32) which is the sliding speed suppressing structure is increased, and the sliding contact with the uneven portion is increased, and the sliding speed is further suppressed.

  The escalator 1 according to the present embodiment has the inclined surface 33 provided with the inclined surface 33 on the rear side demarcation 24 and the concave / convex portion having the sliding speed suppressing structure, and when the load 27 placed on the step 5 slides down, The load 27 slides on the inclined surface 33. Due to the inclined surface 33, the load 27 has an increased area in contact with the slip-down speed suppressing structure. That is, in the escalator 1 according to the present embodiment, the frictional resistance between the load 27 and the sliding speed suppressing structure can be further increased, and the effect of suppressing the sliding speed of the load 27 becomes greater.

  It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible. For example, the above embodiments have been described in detail in order to easily explain the present invention, and the present invention is not necessarily limited to an aspect having all the described configurations. In addition, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment. It is also possible to add the configuration of another embodiment to the configuration of one embodiment. Further, a part of the configuration of each embodiment can be deleted, or another configuration can be added or replaced.
