Embodiments for Carrying Out the Invention

[0009] A lighting fixture used in a passenger conveyor according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7. In the present embodiment, an escalator 10 will be used as an example of the passenger conveyor.

[0010] (1) Structure of the escalator 10 FIG. 1 is a right side view of the escalator 10, and it will be described such that when looking from the upper floor to the lower floor, the upper floor is at the rear and the lower floor is at the front. In FIGS. 1 and 3, the escalator 10 is under construction for installation in the building 1, and the handrail belt is not installed.

[0011] As shown in FIG. 1, a pair of left and right balustrades 14, 14 are erected in the front-rear direction from both the left and right sides of the upper part of the truss 12 spanned between the upper floor and the lower floor of the building 1. This balustrade 14 is composed of a transparent glass plate 24, and a handrail rail 16 is provided in the front-rear direction along the upper end portion of the glass plate 24.

[0012] As shown in FIG. 3, skirt guards 20 are respectively provided inside the lower parts of the pair of left and right balustrades 14, and steps 18 are movably arranged in the front-rear direction between the pair of left and right skirt guards 20. Outer decks 22 are respectively provided outside the lower parts of the pair of left and right balustrades 14, 14.

[0013] (2) LED strip light 40 Next, an LED strip light (hereinafter simply referred to as "light") 40 for illuminating the balustrade 14 will be described.

[0014] As shown in FIGS. 2 and 4, the light 40 is strip-shaped, and as shown in FIG. 5, it is composed of a tape body 42 having an LED substrate and an LED portion 44 provided along one side of the tape body 42. As the LED portion 44 that emits light, for example, chip LEDs (surface-mounted LEDs) are used. When a wiring cord (not shown) is connected to one end of the tape body 42 and power is supplied to the tape body 42 through this wiring cord, the LED portion 44 lights up.

[0015] As shown in FIG. 2, before installation, this strip-shaped light 40 is wound around and stored in a disk-shaped reel 46. When installing on the railing 14, an operator pulls out the light 40 from this reel 46.

[0016] (3) Structure of the upper part of the railing 14 Next, with reference to FIG. 3, the structure of the upper part of the railing 14 will be described.

[0017] As described above, the railing 14 is composed of a transparent glass plate 24, and a metal handrail rail 16 is provided in the front-rear direction at the upper end of this glass plate 24. As shown in FIG. 3, the handrail rail 16 has a fitting part 26 into which the upper end of the glass plate 24 is fitted, lower surface plates 28, 28 that horizontally extend in the left-right direction from the lower end of this fitting part 26, outer surface plates 30, 30 that extend upward from the left and right ends of the lower surface plates 28, 28, and guide parts 32, 32 that extend while inclining slightly downward from the upper end parts of the outer surface plates 30, 30 to both left and right sides. A urethane handrail belt (not shown) has both left and right sides of a flat belt body bent downward, and the bent left and right end parts cover a pair of left and right guide parts 32, 32 and run along the pair of left and right guide parts 32, 32.

[0018] As shown in FIG. 3, a linear synthetic resin cover 34 is fixed in the front-rear direction to the lower part of the lower surface plate 28 of the handrail rail 16 at the upper part of the railing 14 on the side opposite to the step 18. This cover 34 is also called a molding. As shown in FIGS. 4 and 5, its interior is hollow and constitutes a storage part 36, and a groove 38 opens in the front-rear direction on the lower surface of the storage part 36. The left-right length of the groove 38 is formed smaller than the left-right length of the storage part 36.

[0019] As shown in FIG. 5, a strip-shaped light 40 is stored in the storage portion 36 and the groove 38. In this case, the tape body 42 of the light 40 is stored in the storage portion 36, and the LED portion 44 that emits light and is located at the lower part of the tape body 42 is stored in the groove 38 portion. And since the lower surface of the storage portion 36 is open in the front-rear direction by the groove 38, and the length of the groove 38 in the left-right direction (width direction) is formed smaller than the length of the storage portion 36 in the left-right direction (width direction), the light 40 does not fall from the cover 34.

[0020] (4) Lighting attachment jig 50 Next, a lighting attachment jig (hereinafter simply referred to as "jig") 50 for attaching the light 40 to the cover 34 will be described. When using this jig 50, it is in a state where the handrail belt is not yet attached to the handrail rail 16.

[0021] First, the structure of the jig 50 will be described. As shown in FIG. 2, the jig 50 has a sliding portion 52, a hanging portion 54, a shaft portion 56, a guide roller 58, and a branch portion 60.

[0022] The sliding portion 52 is a metal body and is placed on the handrail rail 16 as shown in FIG. 3. A pair of left and right concave portions 64, 64 are provided on the lower surface of a horizontally long rectangular parallelepiped. A pair of left and right guide portions 32, 32 are fitted into the pair of left and right concave portions 64, 64, and the placement surface 62 between the pair of left and right concave portions 64, 64 is placed on the fitting portion 26.

[0023] The hanging portion 54 is for hanging the reel 46 around which the light 40 is wound, as shown in FIG. 2. It is a long and thin rectangular parallelepiped made of metal and extends downward from the left end portion of the lower surface of the sliding portion 52. The length in the vertical direction is about half of the length in the vertical direction of the glass plate 24.

[0024] The shaft portion 56 projects horizontally from the lower end of the right side surface of the hanging portion 54 as shown in FIG. 3, and the reel 46 around which the light 40 is wound can be rotatably attached. Note that the length of the shaft portion 56 is adjusted so that the reel 46 is directly below the cover 34.

[0025] As shown in FIGS. 2 and 3, the guide roller 58 is rotatably provided on a rotary shaft 66 horizontally protruding from the upper part of the right side surface of the suspension part 54, and the upper side of the outer peripheral surface of the guide roller 58 is arranged slightly below the groove 38 of the cover 34. The diameter of the guide roller 58 is smaller than the diameter of the reel 46, and the width of the guide roller 58 is formed slightly larger than the width of the light 40.

[0026] As shown in FIGS. 3 and 4, the branch part 60 extends obliquely upward from the rear surface of the upper part of the suspension part 54, and the position of its tip is near the groove 38 of the cover 34.

[0027] As shown in FIGS. 2 and 3, a holding plate 68 made of rectangular resin is horizontally attached to the upper end surface of the branch part 60 and toward the right side (the railing 14 side). As shown in FIG. 4, it is attached by screws 70.

[0028] As shown in FIGS. 3 and 4, a plate-shaped groove widening part 72 extends upward on the upper side of the right end of the holding plate 68. The groove widening part 72 forms a triangle. As shown in FIG. 6, the central top A of the triangle is inserted from the groove 38 of the cover 34 toward the storage part 36. The left foot part B on the left side and the right foot part C on the right side are located on the upper side of the holding plate 68. The interval L between the left foot part B and the right foot part C has a length slightly wider than the left-right length of the tape body 42 of the light 40, that is, the length in the width direction M (that is, L>M). Therefore, as shown in FIG. 6, when the top A of this groove widening part 72 is inserted to the storage part 36, the left-right interval of the groove 38 is widened by the left foot part B on the left side and the right foot part C on the right side, and the tape body 42 of the light 40 can be inserted.

[0029] (5) Method of using the jig 50 Next, a method for an operator to attach the light 40 to the cover 34 on the left railing 14 using the jig 50 will be described. In the case of this embodiment, it is assumed that the operator attaches the light 40 to the cover 34 on the left railing 14 from the lower floor to the upper floor.

[0030] First, as shown in FIG. 3, attach the reel 46 to the shaft portion 56 at the lower end of the suspension portion 54.

[0031] Next, as shown in FIG. 4, on the lower floor, the operator places the sliding portion 52 on the handrail rail 16 corresponding to the lower end (the foremost part in the front - rear direction) of the cover 34 on the left - hand railing 14 on the lower floor, and suspends the reel 46 at the lower end of the suspension portion 54 outside (left side) of the railing 14.

[0032] Next, as shown in FIG. 6, insert the top A of the groove - widening portion 72 into the groove 38 in front of the lower end of the cover 34, and expand the groove 38 in the left - right direction to the interval L by the left - foot portion B and the right - foot portion C.

[0033] Next, as shown in FIGS. 3 and 4, pull out the tip of the light 40 in the counter - clockwise direction from the reel 46, and position it below the groove - widening portion 72 via the outer peripheral portion of the guide roller 58. Then, as shown in FIGS. 6 and 7, since the groove 38 is expanded in the left - right direction to the interval L by the groove - widening portion 72, store the tip of the tape body 42 of the light 40 with a width - direction length M (where L > M) in the storage portion 36 in front of the lower end of the cover 34, and store the tip of the LED portion 44 in the groove 38. In this case, it is not necessary for the operator to manually expand the groove 38 as in the prior art.

[0034] Next, the operator inserts the tip of the light 40 stored in front of the lower end of the cover 34 from the groove 38 toward the lower end (front) of the cover 34, and fixes it to the storage portion 36 of the cover 34 and the groove 38 in a state where it protrudes slightly from the lower end.

[0035] Next, as shown in FIGS. 1 and 2, the operator slides the sliding portion 52 of the jig 50 upward (rearward). Then, as shown in FIGS. 2 and 4, the reel 46 suspended by the suspension portion 54 rotates counterclockwise, and the guide roller 58 also rotates counterclockwise to pull out the light 40. When the light 40 reaches the position of the groove 38 at this time, as shown in FIGS. 6 and 7, since the groove 38 of the cover 34 has already been expanded in the left-right direction by the groove expanding portion 72, the light 40 can be easily stored in the storage portion 36 and the groove 38. On the other hand, when the groove expanding portion 72 passes, as shown in FIG. 7, the groove 38 of the cover 34 made of synthetic resin returns to its normal left-right length, and as shown in FIG. 5, the light 40 can be held so as not to fall from the cover 34.

[0036] Next, as shown in FIGS. 1 and 2, the operator moves the sliding portion 52 of the jig 50 from the lower floor to the upper floor along the handrail rail 16 of the left railing 14 to store the light 40 up to the upper end of the cover 34 on the upper floor side.

[0037] Next, when the operator stores the light 40 up to the upper end of the cover 34 on the upper floor side, the operator cuts the light 40 so that it protrudes slightly from the upper end of the cover 34 and removes the jig 50 from the left railing 14.

[0038] Finally, the operator connects a wiring cord (not shown) to the tip of the light 40 protruding from the upper end of the cover 34 on the upper floor or the lower end of the cover 34 on the lower floor so that power can be supplied, and then finishes the work.

[0039] Also, when attaching the light 40 to the cover 34 outside the right railing 14, the jig 50 is placed outside the right railing 14, and the light 40 is attached from the upper floor to the lower floor in the same manner as described above.

[0040] (6) Effects According to an embodiment of the present invention, by the operator moving the sliding portion 52 of the jig 50 along the handrail rail 16, the light 40 is pulled out from the reel 46, and there is no need for the operator to pull out the light 40 from the reel 46 as in the conventional case.

[0041] Further, since the guide roller 58 guides the light 40 to the position of the groove 38 of the cover 34, it is not necessary for the operator to manually guide the light 40 to the position of the groove 38.

[0042] Also, conventionally, in an initial property where the escalator 10 has just been installed, non - lighting may occur in some of the LED parts 44 of the light 40. As a cause, when the operator attaches the light 40 to the cover 34, in order to insert the light 40 by manually pressing and expanding the groove 38 of the cover 34 in the left - right direction, during that operation, a load is applied to the LED part 44 and non - lighting is considered to occur. However, in the case of this embodiment, since the interval L between the left foot part B and the right foot part C of the groove expansion part 72 is formed larger than the length M in the width direction of the light 40, when the groove expansion part 72 is inserted into the groove 38, the groove 38 expands in the left - right direction, and the light 40 can be stored in the storage part 36 of the cover 34 and the groove 38. Since there is no need for the operator to manually press and expand as in the conventional case, no load is applied to the LED part 44. Therefore, non - lighting of the LED part 44 does not occur.

[0043] (7) Modification example In the above - described embodiment, the branch part 60 is provided from the rear surface of the suspension part 54, but the branch part 60 may be provided on the front surface and the rear surface respectively. By doing so, when attaching the light 40 to the cover 34 of the left - hand railing 14, it is attached from the lower floor to the upper floor. Further, when attaching the light 40 to the cover 34 of the right - hand railing 14, the screw 70 is removed from the branch part 60 on the rear surface, the holding plate 68 and the groove expansion part 72 are removed, replaced with the branch part 60 on the front surface, and the light 40 can be attached from the lower floor to the upper floor with the jig 50.

[0044] Also, in the above - described embodiment, the shape of the groove expansion part 72 is triangular, but instead, it may be trapezoidal. In this case, the interval between the corner parts forming the bottom side of the trapezoid is set to be longer than the length M in the width direction of the light 40.

[0045] Also, in the above embodiment, the description has been made by applying it to the escalator 10. However, instead of this, it may be applied to a moving walkway. In a moving walkway, the steps are referred to as "steps".

[0046] In the above, one embodiment of the present invention has been described. However, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
