Description

Technical Field

[0001] The present invention relates to a passenger conveyor, and more particularly to a passenger conveyor suitable for having a structure having a light source (eg, LED) for illuminating the vicinity of steps of the passenger conveyor. Background Art

[0002] Generally, in an escalator which is one of passenger conveyors, an apron trim is provided on a wall surface of an apron slightly above the steps as a contact prevention cover to prevent contact with passengers.

[0003] The skirt panel trim is installed to prevent passengers' clothes or shoes from being caught in the gap between the steps and the skirt panel when they are walking on the steps. In addition, a light source is used to illuminate the gap between the steps and the skirt panel in consideration of the safety of the passengers.

[0004] In the prior art, footlights are used as the light sources. The footlights are arranged inside the escalator body, so it is difficult to reliably illuminate the gap between the steps and the skirt with the light source, and the installation of the footlights takes time. It is hoped that these problems can be improved.

[0005] The passenger conveyor described in Patent Document 1 proposes improvements to these problems.

[0006] Patent document 1 states that in order to illuminate a passenger conveyor over a wide range covering the entire range of steps and areas where passengers pass, a light source for irradiating illumination light is disposed at a position closer to the step side than the end face of the skirt plate, and the periphery of the location where the steps and the passenger conveyor are installed is illuminated, and the periphery of the light source is covered with a contact prevention cover for preventing contact between the light source and passengers, and a window member for allowing illumination light to pass is disposed on the contact prevention cover, and the window member is provided with: an upper passing portion for allowing illumination light to pass to a position higher than a horizontal axis passing through the installation position of the light source; and a lower passing portion for allowing illumination light to pass to a position lower than the horizontal axis.

[0010] Technical problem to be solved by the invention

[0011] However, in the passenger conveyor described in the above-mentioned patent document 1, the light source is arranged inside the skirt panel decoration having a D-shaped cross-section, and since the irradiation light irradiated from the light source may pass through an upper passage portion above the horizontal axis passing through the installation position of the light source, or pass through a lower passage portion below the horizontal axis, there is a problem that it is difficult to reliably irradiate the gap between the steps and the skirt panel of the passenger conveyor with sufficient irradiation light.

[0012] The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a passenger conveyor capable of improving the installation work of a light source and reliably irradiating a gap between a step and an apron of the passenger conveyor with sufficient irradiation light.

[0013] Technical solutions to solve problems

[0014] In order to achieve the above-mentioned purpose, the passenger conveyor of the present invention has a plurality of circularly connected steps, a skirt board and a light source for illuminating the vicinity of the steps. A skirt board decoration for preventing the light source from contacting passengers is provided on the wall surface of the skirt board above the steps. The passenger conveyor is characterized in that a light source for illuminating downwards is provided at the lower part of the skirt board decoration in a manner so as to illuminate at least the gap between the steps and the skirt board.

DETAILED DESCRIPTION

[0025] The passenger conveyor of the present invention will be described below based on the illustrated embodiment. In addition, the same reference numerals are used for the same components in each figure.

[0026] [Example 1]

[0027] Figure 1 The overall structure of an escalator 1 as an example of a passenger conveyor according to the present invention is shown. Figure 2 FIG. 1 shows a state in which the LED 7 as a light source illuminates the gap G between the step 5 and the skirt board 3 in the escalator 1 as an example of the passenger conveyor of the present invention.

[0028] As shown in the figure, the escalator 1 of the present embodiment generally comprises: a plurality of circularly connected steps 5 that move in a circular manner; a skirt board 3 that is divided into a plurality of parts in the length direction and whose divided parts are connected by a coupling 3a; a skirt board trim 4 that is arranged on the wall surface of the skirt board 3 on the upper side of the step 5, is divided into a plurality of parts in the length direction, and whose divided parts are connected by a coupling 4a to avoid contact between the LED 7 and the passengers; and an LED 7 that is arranged in each of the divided skirt board trims 4 to illuminate the gap G near the step 5, that is, between the step 5 and the skirt board 3. In addition, reference numeral 2 indicates an inner cover.

[0029] When the escalator 1 ascends, the lower portion is the entrance 1A and the upper portion is the exit 1B. When the escalator 1 descends, the upper portion is the entrance 1A and the lower portion is the exit 1B.

[0030] In the escalator 1 of the present embodiment constructed as described above, the LED 7 is disposed at the lower portion of the skirt trim 4, and the LED 7 is irradiated downward (directly downward) in a manner that illuminates the gap G between the step 5 and the skirt 3 ( Figure 2 The irradiation range is represented by R in FIG.

[0031] By illuminating the gap G between the step 5 and the skirt board 3 mainly downward (directly downward) with the LED 7 in this manner, the gap G between the step 5 and the skirt board 3 can be brightly illuminated, thereby preventing passengers from approaching the gap G.

[0032] The escalator 1 of this embodiment is further described in detail. Figure 2 and Figure 3 As shown, a light source storage portion 9 having an opening portion 9a partially opened for storing LED 7 is formed at the lower portion of the skirt panel trim 4. When the LED 7 is stored in the light source storage portion 9, an LED cover 8 covering the opening portion 9a of the light source storage portion 9 is engaged with the light source storage portion 9.

[0033] The above-mentioned fitting structure between the light source housing 9 and the LED cover 8 is a structure in which the convex portion 8 a formed at the front end of the LED cover 8 fits into the concave portion 4 b formed on the inner surface of the apron trim 4 near the opening 9 a of the light source housing 9 .

[0034] In the escalator 1 of the present embodiment, the relative left and right claws 4b1 and 4b2 are different in length from each other in the claws on the light source housing portion 9 side of the recess 4b formed on the inner surface of the skirt trim 4 near the opening 9a of the light source housing portion 9. That is, the relative left and right claws are formed such that the right claw 4b2 is longer than the left claw 4b1 in the figure.

[0035] In addition, the LED7 in this embodiment is formed into a roughly trapezoidal shape having an upper bottom 7a and a lower bottom 7b, and the lower bottom 7 of the roughly trapezoidal LED7 is inserted into the light source storage portion 9 with the upper side being the upper side from the opening portion 9a on the side of the claw portion 4b2 of the left and right claw portions 4b1 and 4b2 that is longer, thereby storing the LED7 in the light source storage portion 9.

[0036] That is, Figure 3As shown in (a), the lower bottom 7b of the substantially trapezoidal LED 7 is inserted into the light source storage portion 9 with one end of the LED 7 being the upper side from the opening 9a on the side of the claw 4b2 with the longer length of the claws 4b1 and 4b2 on the left and right sides, and the one end of the inserted LED 7 is further pushed toward the right inner side of the light source storage portion 9, and at the same time, the one end of the LED 7 is pushed into the light source storage portion 9 from the claw 4b2 with the longer length (refer to Figure 3 (b)). Then, if Figure 3 As shown in (c), the LED 7 having a substantially trapezoidal shape is stored in the light source storage portion 9 with its lower bottom 7b as the upper side and the upper bottom as the lower side. Finally, as shown in FIG. Figure 3 As shown in (d) , the LED cover 8 is fitted into the light source housing portion 9 .

[0037] This is because, if the lengths of the left and right claws 4b1 and 4b2 are the same, when LED7 is stored in the light source storage portion 9 of the skirt trim 4, LED7 may be unreasonably deformed and damaged (broken or broken). By storing it in the manner of the present embodiment described above, one side of LED7 can be first inserted from the opening 9a on the side of the claw 4b2 with a longer length and then stored in the light source storage portion 9, thereby preventing the above-mentioned damage.

[0038] In the escalator 1 of the present embodiment, the LED cover 8 located on the shorter claw 4b1 side of the left and right claws 4b1 and 4b2 has its front end on the side opposite to the convex side protruding from the front end of the shorter claw 4b1.

[0039] Thus, after the LED 7 is stored in the light source storage portion 9 , when the LED cover 8 is fitted into the light source storage portion 9 , the protrusion of the LED cover 8 serves as a substitute for the shorter claw portion 4 b 1 , thereby preventing the LED 7 from falling off.

[0040] Next, in the escalator 1 as an example of the passenger conveyor of the present invention, the divided portions (connecting portions) of the skirt 3 and the skirt trim 4 divided into a plurality of parts in the length direction are connected by using Figure 4 , Figure 5 and Figure 6 Provide explanation.

[0041] Figure 4 This is a diagram showing a divided skirt panel trim 4 in an escalator 1 as an example of a passenger conveyor according to the present invention, as viewed from the back. Figure 5 The figure shows the positional relationship between the skirt panel trim 4, the skirt panel 3 and the connector storage box 12, and is a figure before the connector storage box 12 is fixed. Figure 6 The figure shows the positional relationship between the divided apron trim 4, the apron 3, and the connector storage box 12, and is a figure after the connector storage box 12 is fixed.

[0042] In the escalator 1 of the present embodiment, the skirt panel decoration 4 is divided into a plurality of parts in the length direction. As described above, each of the divided skirt panel decorations 4 is provided with one LED 7. This is because the escalator 1 has a different floor height H (see FIG. 1 ) according to customer requirements or the building in which it is installed. Figure 1 ) will change. Due to the specifications of LED 7, it is difficult to apply one LED 7 for the distance from the entrance 1A to the exit 1B of the escalator 1. Therefore, from the perspective of on-site operability, it is better to provide one LED 7 for each of the divided skirt panel trims 4 as shown in this embodiment.

[0043] In addition, if Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, there are connectors 10 (10a, 10b) and cables 11 (11a, 11b) for connecting adjacent LEDs 7A and 7B of LEDs 7 set in each of the divided skirt trims 4, and a storage space 4c for storing the connectors 10 (10a, 10b) and the cables 11 (11a, 11b) is provided in the divided skirt trim 4.

[0044] Moreover, in the present embodiment, the skirt board 3 is also divided into multiple parts in the length direction, and the connecting part 3a of the skirt board 3 and the connecting part 4a of the skirt board 4 are provided with notch parts 3c and 3d (not shown) for the connector 10 (10a, 10b) and the cable 11 (11a, 11b) to pass through, and a connector storage box 12 is provided on the back side of the skirt board 3.

[0045] Therefore, even if the size of the connector 10 (10a, 10b) changes due to a change in specifications, the connector 10 (10a, 10b) can be stored using the storage space 4c of the skirt trim 4 or the connector storage box 12 on the back of the skirt 3.

[0046] When the divided skirt trim 4 is provided with a storage space 4c for accommodating the connector 10 (10a, 10b) and the cable 11 (11a, 11b), after the connectors 10a, 10b of the components of adjacent skirt trims 4 are connected to each other (the combination of LED 7 and LED cover 8 is regarded as 1 group, and such groups are connected to each other), the inner cover 2 and the skirt 3 are fastened together with bolts 13 on the skirt trim 4 while the connector 10 (10a, 10b) and the cable 11 (11a, 11b) are accommodated in the storage space 4c.

[0047] In addition, the notch 3c of the skirt board 3 and the notch (not shown) of the skirt board trim 4 are provided for the connector 10 (10a, 10b) and the cable 11 (11a, 11b) to pass through the connecting portion 3a of the skirt board 3 and the connecting portion 4a of the skirt board trim 4, and when the connector storage box 12 is provided on the back of the skirt board 3, after the connectors 10a, 10b of the adjacent skirt board trim 4 components (the combination of the LED 7 and the LED cover 8 is regarded as one group, such groups are connected), the connectors 10a, 10b and the cables 11a, 11b are stored in the connector storage box 12. The cables 11a, 11b are released so as not to be caught by the notch 3c of the skirt board 3 and the notch of the skirt board trim 4, and the skirt board trim 4 is fixed to the skirt board 3 by the bolt 13.

[0048] According to this embodiment, the installation operation of the LED 7 can be improved, and the gap G between the step 5 and the skirt board 3 of the escalator 1 can be reliably irradiated with sufficient irradiation light, thereby preventing passengers from approaching the gap G.

[0049] Furthermore, when the LED 7 is housed in the light source housing portion 9 of the apron trim 4 , the LED 7 does not undergo unreasonable deformation, and damage (breakage or cracking) can be prevented.

[0050] Furthermore, after the LED 7 is stored in the light source storage portion 9 , the LED cover 8 is fitted into the light source storage portion 9 , whereby the protrusion of the LED cover 8 replaces the shorter claw portion 4 b 1 , thereby preventing the LED 7 from falling off.

[0051] In addition, the present invention is not limited to the above-mentioned embodiments, and includes various modified examples. For example, the above-mentioned embodiments are contents described in detail in order to explain the present invention in an easy-to-understand manner, and are not limited to having all the structures described. In addition, a part of the structure of a certain embodiment can be replaced with the structure of other embodiments, and the structure of other embodiments can be added to the structure of a certain embodiment. In addition, with respect to a part of the structure of each embodiment, other structures can be added, deleted, or replaced.
