The escalator 1 is installed across the upper floor and the lower floor, and includes a moving handrail 2 for holding passengers, a balustrade 3 that supports the moving handrail 2, and an outside that holds the balustrade 3 from the outside. A deck 4, a control device 5 that controls the escalator 1, and a bottom 6 in which an oil pan or the like is disposed below the escalator 1 are provided.

  Moreover, 1st Embodiment of this invention shall be equipped with the escalator 1a, 1b, 1c similar to the escalator 1, and shall have a total of four escalators. Here, the escalator 1 performs the ascending operation from the first floor to the second floor, the escalator 1a performs the descending operation from the second floor to the first floor, the escalator 1b performs the ascending operation from the second floor to the third floor, and the escalator 1c. Is a descent operation from the third floor to the second floor.

  Moreover, these escalators 1a, 1b, and 1c cross each other. And a passenger | crew is in the narrow angle part formed between the moving handrail 2 of the escalator 1 and the bottom part 6a of the escalator 1a, and the narrow angle part formed between the moving handrail 2 of the escalator 1 and the bottom part 6b of the escalator 1b. In order to prevent the vehicle from being pinched, a swingable protective device 7 is arranged so as to be aware of the danger when the passenger touches it, and the protective device 8 firmly fixed to the bottom 6a of the escalator 1a and this A cylindrical body 9 is arranged in front of the protection device 7.

  The cylindrical body 9 is made of a transparent acrylic material made of the same material as that of the cylindrical body attached to the protective device 7, and is suspended so as to be swingable so that it does not cause injury when a passenger collides. ing. Further, the length of the cylindrical body 9 may be hung so that the lower end is 200 mm or more below the upper end of the moving handrail 2.

  As shown in FIG. 2, a camera 10 for monitoring a passenger of the escalator 1, that is, a camera 10 on which a dome 10 </ b> A for photographing how to ride the passenger on the escalator 1 is disposed at the inner upper end of the cylindrical body 9. Yes.

  As shown in FIG. 3, the mounting jig 11 has a hole of a predetermined diameter for connecting the cable connector 19a of the wiring cable 19 routed from the bottom portion 6a of the camera 10 and the escalator 1a through the outer deck 4 to the center. 11a and a plurality of mounting holes 11b provided on the circumference of a predetermined radius from the center of the hole 11a having a predetermined diameter and screwed to the upper mounting portion of the camera 10 at a predetermined angular interval from the center. A disc 11A and a pair of suspension plates 11B are provided so as to be opposed to each other centering on a hole 11a having a predetermined diameter provided in the camera mounting disc 11A. Here, the suspension plate 11B includes a screw hole 11c provided above the camera attachment disk 11A by a predetermined dimension, and a suspension 13 for attaching the attachment jig 11 to the suspension fitting 12 provided near the end of the suspension plate 11B. A pair of suspension holes 11d are provided for mounting.

  Further, as shown in FIG. 1, the screw holes 11c and the suspension holes 11d are provided so that the camera mounting disk 11A is kept horizontal when the cylindrical body 9 is suspended from the bottom 6a of the escalator 1a. .

  That is, when the bottom 6a of the escalator 1 is inclined by about 30 ° with respect to the horizontal direction, as shown in FIG. 3, the suspension plate 11B of the mounting jig 11 has an extension line of the suspension hole 11d extending from the bottom of the escalator 1a. One of them is extended by a predetermined dimension so that the camera mounting disc 11A is parallel to 6a and the suspension hole 11d is provided in the vicinity of the upper end of the suspension plate 11B.

  In this way, by adjusting the installation position of the suspension hole 11d according to the inclination angle of the bottom portion 6 of the escalator 1, the suspension 13 can be used in the same shape and the camera mounting disk 11A becomes horizontal. The viewing angle can be easily adjusted.

  Next, the influence of the illumination provided in the building on the light will be described below.

  As shown in FIG. 2, a phenomenon in which light C having an incident angle α that is smaller than the critical angle α0 proceeds inside the cylindrical body 9 while reflecting the inner surface of the cylindrical body 9 and enters the field of view of the camera. That is, reflection occurs. As a countermeasure against this reflection of light, it is necessary to suppress reflection on the inner surface of the cylindrical body 9 at least before outside light reaches the camera field of view.

  Next, if an antireflection body 15 such as a sticker or a paint is provided on the half circumference opposite to the camera photographing direction of the cylindrical body 9, no reflection will occur, but the range in which such an antireflection body 15 is provided. explain.

  First, when the light C of the incident angle α reflects the inner surface of the cylindrical body 9 having the inner diameter Di, proceeds in the vertical plane passing through the central axis of the cylindrical body 9, and reaches the lower end point A of the camera field, The distance L2 from the projection point B reflected two points before the lower end point A is obtained by L2 = 2 × Di × tan α. As described above, antireflection such as sticking a sticker or applying paint on the opposite surface of the camera shooting direction from the lower end point A to the projection point B in the vertical direction and the left and right viewing angles of the camera in the left and right direction. By providing the body 15, it is possible to suppress external light from being reflected in the camera field of view.

  Further, since L2 approaches infinity as the incident angle approaches 90 degrees from the critical angle α0, ideally, it is desirable that all the half surfaces in the length direction of the cylindrical body 9 be antireflection bodies. Considering the illumination conditions, it is rare that the incident angle α is in the vicinity of 90 degrees, and the length obtained by L2 = 2 × Di × tan α0 is assumed to be mainly suppressed when the incident angle α of light is α <α0. A sufficient effect can be obtained.

  The range in which the reflection is efficiently suppressed is the distance L2 obtained by L2 = 2 × Di × tan α0 from the camera visual field lower end point A. In this embodiment, the above-described antireflection body such as sticking a sticker or applying a paint is used. 15 is a length Ld obtained by adding a distance L1 from the lower end point A of the camera field to the upper end of the cylindrical body 9 and L2 obtained from the lower end point A of the camera field by L2 = 2 × Di × tan α0. 15 positions can be adjusted without measuring.

  As shown in FIG. 4, the projection points F1 and G1 on the outer peripheral surface of the cylindrical body 9 at the left and right viewing angle θ2 of the camera 10 and the anti-camera at the viewing angle θ2 from the projection points F1 and G1 on the outer peripheral surface. The projection points F2 and G2 on the inner peripheral surface of the cylindrical body 9 extended to the visual field side are obtained, and the maximum reflection of light at the left and right viewing angles θ2 is the arc Lb1 of the projection points F1 and G1 on the outer peripheral surface. The antireflection body 15 may be provided in the range. At least, the antireflection body 15 provided on the arc Lb2 formed by the respective contacts on the outer peripheral surface obtained by extending the contacts F2, G2 on the inner peripheral surface from the center of the cylindrical member 9 is also reflected by the cylindrical member 9. Since the light does not enter the left and right viewing angles θ2 of the camera 10, a sufficient effect can be obtained.

  That is, the antireflection body 15 for the left and right viewing angle θ2 of the camera 10 may be provided on the inner peripheral surface of the cylindrical body 9 in the range from the arc Lb2 to the arc Lb1, and the cylindrical body 9 is considered in consideration of the design surface. The vicinity of half a circle is suitable.

  Next, as shown in FIG. 5, the L-shaped integral opaque film 17 including the cover body 16 and the antireflection body 15 has a length La from the upper end of the cylindrical body 9 to the lower end of the cover body 16. A strip shape having a width Wd in the vicinity of a half circumference of the cylindrical body 9 in the range from the arc Lb2 to the arc Lb1 and Ld plus the length Lc can be screwed at an angular position that matches the angle of the camera 10 A plurality of holes 17a into which the screws 14 can be inserted are provided in the upper portion so that the inner surface on the camera 10 side has a low brightness, for example, black to reduce the influence of the reflection, but on the other hand, any color may be used. You may draw a word or a pattern, and you may stick a sticker.

  Since the cover body 16 and the antireflection body 15 are integrated, there is a wasteful portion when the L-shaped opaque film 17 is cut out, but the attachment to the cylindrical body 9 is easy and can be performed in a short time. .

  Further, the material of the L-shaped opaque film 17 can be colored and easily deformed, and may be a resin such as polyester or vinyl chloride, paper, or cloth, and the handling of 0.3 mm-thick vinyl chloride is easy.

  The cover body 16 has a substantially belt-like shape. In the vicinity of the upper side of the cover body 16, the upper end portion of the cylindrical body 9 and the dimension of a pair of holes (not shown) and the dimension between the pair of holes (cylindrical shape) Two pairs of holes 16a are provided from the upper side of the cover body 16 with the same dimension as the semicircular dimension of the inner surface of the body 9, and one hole 16a is provided on each of the left and right sides of the holes. The cover body 16 becomes an annular body having the same dimensions as the inner periphery of the cylindrical body 9 by being screwed with the screw 14 in accordance with the screw hole 11c of the above, and the upper side of the cover body 16 is aligned with the upper end of the cylindrical body 9 The two holes 16a coincide with a pair of holes (not shown) of the cylindrical body 9.

  Here, the cover 16 may be made of the same material as the L-shaped opaque film 17 such as polyester, vinyl chloride, paper, or cloth. The same material as the L-shaped opaque film 17 and the upper part of the camera 10 may be used. A similar color is desirable in terms of design.

  Next, the attachment procedure of the camera 10 will be described.

  As shown in FIGS. 6 and 7, the camera 10 is attached to a mounting hole 11b of the camera mounting disk 11A via a screw (not shown), and a hole 11a having a predetermined diameter provided at the center of the bottom surface of the mounting jig 11. The cable connector 19a of the wiring cable 19 wired through the outer deck 4 from the bottom 6a of the escalator 1a is connected to the upper mounting portion 10a of the camera 10, and the hanging metal fitting 12 is fixed to the bottom 6a of the escalator 1a with the fixing bolt 12a. The camera 10 is swung by a lifting tool 13 in a pair of suspension holes 11d respectively provided in the vicinity of the end of a suspension plate 11B that is fixed to the camera mounting disk 11A of the mounting jig 11 and is established facing the camera mounting disk 11A. The viewing angle of the camera 10 is adjusted by hanging as possible.

  As described above, since the camera 10 can be adjusted without attaching the cylindrical body 9, the operation can be easily performed.

  The detachable light-reflective body 15 having a predetermined length, which will be described later, has a length dimension larger than the range of the vertical viewing angle θ1, and is substantially half the circumference of the cylindrical body 9 on the side opposite to the angle of view of the camera 10. It is pasted to cover.

  Note that the anti-reflective body 15 is printed with a text ("illustration" or "mark") such as "Camera is in operation" or "Be careful about getting on the board" to prevent passengers from mischief and alerting a narrow angle. Doubles as

  Moreover, it can also visually recognize from the passenger of the adjacent escalator by printing on a back surface. Here, by providing the antireflection body 15 inside the cylindrical body 9, the effect of suppressing reflection can be increased.

  The antireflection body 15 has a length from the upper end portion of the cylindrical body 9 to at least the lower end portion of the mounting jig 11, and is formed of an opaque film that covers the inner surface of the cylindrical body 9. Is mounted between the inner surface of the cylindrical body 9 and the mounting jig 11 and the camera 10 to obscure the camera 10 and the mounting jig 11 and conceal the presence of the camera 10 (at least the cylindrical body). 9) What is necessary is that blinding from the upper end portion to the lower end portion of the mounting jig 11 is possible.

  In the lower part of the cylindrical body 9, an excessive deflection of the cylindrical body 9 is caused by a hole provided at the lower end of the cylindrical body 9 and a mounting jig (not shown) provided on the outer deck 4 with a wire 18 (or a chain). It is preventing.

  Further, the video data of the camera 10 is sent to an image memory (not shown) built in the monitoring unit 20 installed on the outer deck 4 via a wiring cable 19 wired from the bottom 6a of the escalator 1a through the outer deck 4. It is to be recorded.

  A cylindrical body 901 to 905 in which a camera (not shown) is built is also arranged in front of the protective devices 701 to 705 in each narrow angle portion shown in FIG. 1, and the monitoring unit 201 is built in the cylindrical body 905. Connected to the monitoring unit 202, two cameras (not shown) of the cylindrical bodies 901 and 902 are connected to the monitoring unit 202, and two cameras (not shown) of the cylindrical bodies 903 and 904 are also connected to the monitoring unit 203. Are connected to each other.

  Next, a method of attaching the T-shaped or L-shaped opaque film 17 in which the cover body 16 and the antireflection body 15 are integrated will be described.

  First, as a preparatory work, the camera 10 is mounted on the mounting jig 11, and a curved wrinkle is attached below the opaque film so that the opaque film 17 abuts on the inner peripheral surface of the cylindrical body 9 (the black side with low brightness is on the inside). To be).

  First, the annular opaque film 17 is put inside the cylindrical body 9, and a pair of holes (not shown) of the cylindrical body 9 and the holes 17 a of the opaque film 17 are aligned.

  Second, the camera 10 is mounted from above the cylindrical body 9 so that the cylindrical body 9 and the opaque film 17 do not shift, and a hole (not shown) of the cylindrical body 9 and a hole 17a of the opaque film 17 and the mounting jig are attached. Adjust so that the screw hole 11c of the tool 11 matches.

  Third, the screw 14 is screwed into the screw hole 11c. Here, the screw 14 has a cylindrical shape when the screw 14 is screwed into the screw hole 11c of the mounting jig 11 by using a stepped screw that is not threaded by a predetermined dimension from below the neck shown in FIG. If a distant piece having a predetermined thickness that does not come into contact with the inner wall of the body 9 is used, it is possible to prevent cracking and cracking of the mounting portion of the cylindrical body 9.

  Further, when using a general screw 14 threaded from under the neck, a distant piece having a predetermined thickness that does not contact the inner wall of the cylindrical body 9 between the cylindrical body 9 and the screw hole 11c of the mounting jig 11. If this is used, cracks and cracks in the attachment portion of the cylindrical body 9 can be prevented.

  Thus, the opaque film 17 can be easily attached to the inside of the cylindrical body 9, so that reflection by light can be effectively suppressed and mischief such as graffiti can be prevented.

  Here, if there is a deviation between the shooting direction of the camera 10 and the traveling direction of the escalator, the characters described on the antireflection body 15 of the opaque film 17 become difficult to see, so a plurality of holes 17a provided on the upper portion of the opaque film 17 are provided. By appropriately changing, the traveling direction of the escalator and the opaque film 17 are in the same direction, and the characters of the antireflection body 15 of the opaque film 17 are easily readable by the passenger of the escalator.

  Since it comprised in this way, since the cylindrical body 9 hung down ahead of the protective device 7 arrange | positioned at a narrow-angle part, and the camera 10 for monitoring were accommodated inside this cylindrical body 9, The camera for monitoring can be installed in a good position that can monitor the rising and falling state of passengers without being affected by the ceiling and wall structure of the building around the escalator, and was received at the above mentioned of the building The camera installation regulations can be eliminated, and the installation cost of the escalator monitoring device can be reduced. The same applies to the other cylindrical bodies 901-905.

  In addition, since the camera 10 is housed inside the cylindrical body 9 without being exposed, it is possible to ensure excellent design and prevent mischief of the passenger 10. In addition, since the shape of the mounting jig 11 of the camera 10 is a shape in which the camera mounting disk 11A and the suspension plate 11B are provided, the members of the mounting jig 11 and the lifting tool 13 are outside the outer periphery of the cylindrical body 9. Since it does not come out, the occurrence of injury can be suppressed even if the upper end portion of the cylindrical body 9 is touched by mistake when the escalator 1 is traveling.

  In addition, the camera provided in the cylindrical body 901 can monitor not only passengers rising on the escalator 1, but also passengers crossing and descending on the adjacent escalator 1a. Monitoring is possible.

  In addition, since the antireflection body 15 of the opaque film 17 covers about half the circumference of the camera 10 on the side opposite to the angle of view, external light such as illumination reflected through the cylindrical body 9 enters the viewing angle of the camera. Therefore, it is possible to obtain an excellent image that is less affected by building lighting or external light.

  Further, since the cover body 16 of the opaque film 17 is provided on the upper inner peripheral surface of the cylindrical body 9, the mounting jig 11, the camera upper mounting portion 10a, the cable connector 19a and the like are not visible to the passengers. An escalator monitoring device excellent in design can be provided.

  Further, since the cover body 16 and the antireflection body 15 are integrated with each other, the cylindrical body 9 can be attached to the inner surface easily and in a short time, and a pair of the cover body 16 provided on the cylindrical body 9 is provided. Since a plurality of pairs of holes that match these holes are provided, the camera can be screwed into the screw holes of the mounting jig 11 of the camera without affecting the angle of the camera.
