Description

  The present invention relates to passenger conveyors such as escalators and electric roads, and more particularly to a passenger conveyor provided with a Braille block for visually impaired persons on a boarding / exiting floor for boarding / exiting a stepping board that circulates and moves.

  Conventionally, a passenger conveyor provided with a Braille block on the landing floor has already been proposed as described in Patent Document 1, for example.

JP-A-9-323880

  The invention described in Patent Document 1 requires a device for fixing the Braille block because the Braille block and the getting-on / off floor are separate from each other, and the fixation is loosened and floated during long-term use. There is a risk of crawling and falling.

  Furthermore, in order to fix the braille block, there is a problem that the getting-on / off floor must be improved accordingly. Furthermore, since the boarding / exiting floor is disposed close to the tread board and is flush with the floor surface, if the Braille block is thick, it may be impossible to attach to the boarding / exiting floor.

  In addition, there is a technique for sticking the braille block to the boarding / exiting floor surface, but the sticking may be lowered and peeled off during long-term use.

  An object of the present invention is to provide a passenger conveyor in which a Braille block is not loosened or lifted, and can be easily installed on a boarding / exiting floor.

  In order to achieve the above-mentioned object, the present invention forms a braille block by providing a plurality of protrusions on a portion of a floor board constituting a boarding / exiting floor that is close to the floor of a building.

  By integrally molding the braille block on the floor board by, for example, a press as described above, the conventional inconvenience of attaching the separate braille block to the boarding / exiting floor can be eliminated. In other words, by integrally molding the braille block on the floor plate, it is not necessary to fix the braille block of another configuration on the boarding / exiting floor. The risk of hitting and falling is also eliminated. Furthermore, by integrally molding the braille block on the floor plate, there is no need to improve the boarding floor to fix the braille block of another configuration, and the braille block does not peel off during long-term use.

  As described above, according to the present invention, it is possible to obtain a passenger conveyor in which the braille block is not loosened or lifted, and the braille block can be easily installed on the boarding / exiting floor.

  Hereinafter, a first embodiment of a passenger conveyor according to the present invention will be described along the escalator shown in FIGS.

  In general, the escalator 1 includes a frame 4 supported across an upper floor 2 and a lower floor 3, a step 5 having a step board 5S on the upper surface, and a balustrade 6 erected on both sides in the moving direction of the step 5. The movable handrail 7 is guided and moved by the periphery of the balustrade 6 and the boarding / exiting floors 8A and 8B for getting on and off the step 5 are provided.

  A plurality of the steps 5 are connected to the step chain 9 in an endless manner, and are circulated and guided by guide rails (not shown) provided on the frame body 4. The step chain 9 is wound around a drive sprocket 10 supported on one side in the longitudinal direction of the frame body 4 and a driven sprocket 11 supported on the other side in the longitudinal direction of the frame body 4. It has been. The drive sprocket 10 is driven by a drive device 12 installed in the vicinity, and the moving handrail 7 is also driven in synchronization with the step 5 by the power of the drive device 12.

  The boarding / exiting floor 8A (8B) is fixed to the walking portion 13 which is flush with the upper floor 2 and the lower floor 3 and is inclined so that the tip approaches the step 5, and the distal portion of the walking portion 13. A comb body 14 that meshes with the cleat formed on the tread plate 5S of the step 5 in a non-contact state is provided.

  The walking portion 13 includes a floor plate 15 and supports 16 and 17 that support the floor plate 15 from below, and the support 16 also fixes the comb body 14.

  Further, the floor plate 15 is provided with a first floor plate 15A, a second floor plate 15B, a third floor plate 15C, a first floor plate 15C for maintenance and inspection of the drive sprocket 10, the driven sprocket 11, the drive device 12 and the like installed below. The four floor plates 15D are divided into four parts, and are configured to be detachable from the frame body 4 together with the support bodies 16 and 17 fixed thereto.

  Further, although not shown in the drawings, the floor plates 15A to 15D are provided with a non-slip pattern on the surface so as to prevent pedestrians from slipping. A braille block 19 is formed on the first floor plate 15 </ b> A by providing a plurality of protrusions so as to protrude to the surface side. These anti-slip patterns and Braille blocks 19 are formed by, for example, a press. By performing such press processing, work hardening is obtained and strength is increased, so that the floor board 15 can be made thin and light. .

  The Braille block 19 is a warning block with a standardized size of a dotted projection that warns a visually handicapped person that it is an entrance / exit of the escalator 1. Rather than providing the Braille block 19, by providing the Braille block 19 in front of 30 cm or more, it is possible to alert the visually handicapped person early.

  By using the Braille block 19 as a warning dot-like projection, a visually impaired person can detect that the entrance / exit of the escalator 1 is in the vicinity from the upper floor 2 and the lower floor 3. Although it is conceivable that the Braille block 19 is provided near the comb body 14 side of the getting-on / off floor 8A (8B), when the Braille block 19 is provided only near the comb body 14 side, the step that is rotating is the tip. Since 5 is immediately present, it is dangerous, and by providing a Braille block 19 on the side close to the upper floor 2 and the lower floor 3 in advance, it is informed that it is a boarding / exiting part of the escalator 1 and calls attention. be able to. A visually handicapped person who wants to use the escalator 1 can proceed carefully, or a visually handicapped person who does not use the escalator 1 can take an action of leaving the escalator 1.

  In addition, by dividing the first floor plate 15A as shown by the two-dot chain line in FIG. 2, the press work for forming the braille block 19 can be facilitated. That is, if a plurality of protrusions are simultaneously formed by press working over a wide range, the deformation of the material becomes large, and it becomes difficult to form a Braille block having a specified dimension. Therefore, the Braille block 19 having a specified size is obtained by reducing the deformation of the material by pressing the floor board which is subdivided.

  As described above, according to the present embodiment, since the Braille block 19 is directly formed on the first floor plate 15A, the conventional inconvenience in which the Braille block and the getting-on / off floor are separately configured can be eliminated.

  In addition, a braille block 19 is formed on the first floor plate 15A by pressing or the like, so that a cavity 19A is formed on the back side of the braille block 19, and the presence of this cavity 19A allows a visually handicapped person to braille at the tip of a white cane. When the block 19 is stroked, the metal sound is amplified and reverberated, and the presence of the braille block 19 can be emphasized.

  FIG. 4 shows a second embodiment of a passenger conveyor according to the present invention, and a configuration different from the first embodiment is a forming structure of the braille block 19 when the guide fence 18 is not present.

  That is, when the guide fence 18 does not exist, as described above, a general passerby crosses the boarding / exiting floor 8A (8B). However, since a general passer-by can see the presence or absence of an escalator, there is no problem even if it crosses the boarding / exiting floor 8A (8B), but a visually handicapped person cannot confirm the presence of the escalator, so there is a risk of touching the movable moving handrail 10 or the like. Exists.

  Therefore, when the guide fence 18 does not exist, the Braille block 20 is formed in a U-shape in three directions approaching the upper floor 2 (lower floor 3) of the passenger floor 8A (8B). The Braille block group 20A warns when the passenger goes straight along the moving direction of the step 5, and is the same as in the first embodiment. The Braille block groups 20B and 20C are the upper floor 2 (lower floor). A warning is given when crossing the floor 3) from the floor 8A (8B).

  In this way, by forming the braille blocks 20 on the three sides of the getting-on / off floor 8A (8B), it is possible to provide a finer service to the visually impaired.

  In FIG. 4, the same reference numerals as those in FIGS. 1 to 3 indicate the same parts, and the description thereof will be omitted. Further, considering the ease of press work, the first floor plate 15A is changed into a braille floor plate 15a where the Braille block 20 exists and a floor plate 15b where the Braille block 20 does not exist, as shown by a two-dot chain line in FIG. It is also possible to divide and further subdivide the braille floor plate 15a into a size that facilitates the press work.

  By the way, in this Embodiment, although the braille blocks 19 and 20 were shape | molded over the full width of the boarding / alighting floor 8A (8B), it is not necessary to shape | mold to the full width, for example, as shown in FIG. Even if the dotted block 21 is formed in the range of the safe boarding width Ws that is slightly smaller than the width dimension W, an equivalent warning can be given to the visually handicapped person.

  Specifically, in order to safely guide a visually impaired person to the step 5 of the escalator 1, it is necessary to inform the width dimension of the step 5. However, when notifying the full width dimension W of the step 5, it may be possible to get in such a way that the foot is in contact with the skirt guard SG, which is not recommended for safety. Therefore, the dotted block 21 is provided so as to inform the safe entry width Ws that the passenger can safely ride on, except for the caution band (not shown) displayed on the left and right sides of the full width dimension W of the step 5. It is installed in a range that matches this safe boarding width Ws. Therefore, among the first to fourth floor plates 15A to 15D constituting the floor plate 15, the Braille block 21 is formed on the first floor plate 15A according to the safety boarding width Ws. Then, the first floor board 15A is divided into a braille floor board 15a in which the braille block 21 is present and a floor board 15b in which the braille block 21 is not present, and the braille floor board 15a is further subdivided and pressed as indicated by a two-dot difference line. It is easy to work.

  Thus, the visually impaired person is guided on the step 5 away from the skirt guard SG by notifying the safe boarding width Ws narrower than the full width dimension W of the step 5 by the dotted block 21.

  As described above, according to the embodiments of the present invention, the slack and lifting of the braille block are eliminated, and the installation of the braille block on the boarding / exiting floor can be easily performed by a press or the like simultaneously with the anti-slip pattern. .

  By the way, although each said embodiment demonstrated the escalator as a passenger conveyor, it cannot be overemphasized that this invention is applicable also to an electric road.
