Summary of the Invention

Problems to be Solved by the Invention

[0004] In a structure in which a shielding plate (hereinafter referred to as a "lighting cover") is attached, such as the lighting device for an elevator of Patent Document 1, if the distance between a light source such as an LED or an LED panel and the lighting cover is short, the light (irradiation light) emitted from the light source reaches the lighting cover without being sufficiently diffused, and the outline of the light source becomes prominent on the lighting cover. Therefore, in order to ensure a sufficient distance between the light source and the lighting cover, it was necessary to increase the thickness of the ceiling (the thickness of the box body in Patent Document 1).

[0005] The object of the present invention is to provide an elevator device equipped with a lighting device that can sufficiently diffuse the irradiated light before it reaches the lighting cover without increasing the distance between the light source and the lighting cover. [Means for solving the problem]

[0006] To solve the above problems, the elevator device of the present invention is In an elevator system equipped with a lighting device on the ceiling of the elevator car, The lighting device comprises a light source and a cover member positioned below the light source and transmitting light into the interior space of the elevator car. The cover member has a transparent region that allows transmitted light to reach the interior space of the elevator car. The light source is positioned horizontally on the outside of the transparent region of the cover member, and is positioned so that the irradiated light passes through the transparent region. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide an elevator system equipped with a lighting device that can sufficiently diffuse the irradiated light before it reaches the lighting cover without increasing the distance between the light source and the lighting cover. Other issues, configurations, and effects not mentioned above will be clarified by the following description of the embodiments. [Brief explanation of the drawing]

[Figure 7] Figure 6 is an explanatory diagram illustrating the problems in the lighting device shown. [Modes for carrying out the invention]

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0010] The configuration of the elevator system 100 will be described with reference to Figures 1 and 2.

[0011] Figure 1 is a cross-sectional view parallel to the vertical direction showing the configuration of an elevator system 100 according to one embodiment of the present invention. In Figure 1, the size of the hoistway HW and the positions and orientations of the equipment placed within the hoistway HW are depicted in a form different from reality in order to explain the configuration of the elevator system 100 in an easy-to-understand manner. Also, in Figure 1, the elevator car 104 is shown stopped at the landing 112 on the top floor.

[0012] The x-axis, y-axis, and z-axis directions are defined as shown in Figure 1. The x-axis direction is horizontal and coincides with the width direction of the elevator car 104. The y-axis direction is horizontal and coincides with the depth direction of the elevator car 104. The z-axis direction is vertical (up and down) and coincides with the up and down direction of the elevator car 104.

[0013] The elevator system 100 includes a car 104 and a counterweight 105 that move up and down within the hoistway HW, a hoisting machine 102 around which the main rope 107 connected to the car 104 and the counterweight 105 is wound, a guide rail 109 erected in the hoistway HW to guide the up and down of the car 104 and the counterweight 105, a control panel (control device) 101 for controlling the elevator system 100, and a speed governor 111 for detecting the up and down speed of the car 104.

[0014] The car 104 and the counterweight 105 are provided inside a hoistway HW provided in a building and are suspended in a pendulum manner by a main rope 107. One rope end 107a of the main rope 107 is supported near the ceiling of the hoistway HW, is passed around a pulley 104b provided on the lower surface side of the car 104, and is wound around a sheave 102b of a hoisting machine 102. The other rope end 107b side of the main rope 107 wound around the sheave 102b of the hoisting machine 102 is supported by a hoisting machine support portion 120 via a pulley 105a of the counterweight 105.

[0015] The car 104 is electrically connected to a control panel 101 by a tail cord (not shown), receives power supply via the tail cord, and exchanges control signals and various signals with the control panel 101. A buffer 106 is disposed on the bottom surface of the hoistway HW below the car 104 and the counterweight 105. In FIG. 1, the buffer 106 for the counterweight 105 is shown, and the buffer for the car 104 is not shown.

[0016] The hoisting machine 102 is supported by a hoisting machine support portion 120 and is disposed at the top of the hoistway HW. The control panel 101 is disposed at the top of the hoistway HW and is disposed in the vicinity of the hoisting machine 102. The elevator device 100 of the present embodiment is a machine roomless elevator device in which devices such as the control panel 101 and the hoisting machine 102 are disposed in the hoistway HW. However, the elevator device to which the present invention is applied is not limited to a machine roomless elevator device, nor is it limited to a rope-type elevator device.

[0017] The car 104 and the counterweight 105 are guided in the vertical direction (hoisting direction) by guide rails 109 erected in the vertical direction (height direction) along the inner wall of the hoistway (hereinafter referred to as the hoistway wall) HW1. The guide rails 109 are fixed to the hoistway wall HW1 by rail brackets (not shown) while being supported by a support base (guide rail support base) 103.

[0018] That is, the elevator apparatus 100 of this embodiment includes an elevator car 104 and a counterweight 105 connected to a main rope 107. The elevator car and the counterweight are guided by a guide rail 109 and move up and down in a hoistway HW. Here, "connected" does not mean that the main rope 107 is fixed to the elevator car 104 and the counterweight 105, but includes being wound around the pulleys 104b and 105a as described above.

[0019] The speed governor 111 is a device that detects the up-and-down speed of the elevator car 104, and includes a main body (speed governor sheave) 111a, an upper turning pulley 111b disposed above the main body 111a, a lower turning pulley 111c disposed below the main body 111a, and a speed governor rope 111e wound around the main body 111a, the upper turning pulley 111b, and the lower turning pulley 111c.

[0020] FIG. 2 is a cross-sectional view parallel to the horizontal direction showing the configuration of the elevator apparatus 100 according to an embodiment of the present invention. In FIG. 2, the state of viewing the hoistway HW from above the elevator car 104 is illustrated, and the ceiling portion (above the car) 104c of the elevator car 104 is depicted.

[0021] A car door 104a is provided on a side surface of the elevator car 104 facing the elevator hall 112. On the elevator hall 112 side, an entrance / exit door 112a is provided at a position facing the car door 104a. A space for arranging devices (in-hoistway devices) such as a hoisting machine 102, a speed governor 111, and a control panel 101 is provided between the other side surfaces of the elevator car 104 except the side surface where the car door 104a is provided and the hoistway wall HW1.

[0022] To enable this arrangement, the hoisting machine 102 is a thin hoisting machine in which the dimension of the sheave 102b in the rotation axis direction (x axis direction) is smaller than the dimension in the horizontal direction and in the direction perpendicular to the rotation axis direction (y axis direction). In this embodiment, the hoisting machine 102 and the governor 111 are arranged in the space to the left of the elevator car 104 when viewed from the elevator hall 112 side. The hoisting machine 102 is fixed to the hoistway wall HW1 by a hoisting machine support 120 (see Figure 1). The hoisting machine support 120 is fixed to the car guide rail 109A and the counterweight guide rail 109B, and the hoisting machine 102 is fixed to the hoistway wall HW1 via the guide rail 109.

[0023] The control panel 101 is located in a space to the right of the elevator car 104 when viewed from the elevator hall 112. The control panel 101 is fixed to the hoistway wall HW1 by a control panel bracket (not shown). In this case, the control panel bracket is fixed to the car guide rail 109A, and the control panel 101 is fixed to the hoistway wall HW1 via the car guide rail 109A.

[0024] The elevator device 100 in this embodiment is of the traction type, in which the hoisting machine 102 frictionally drives the main rope 107 to raise and lower the elevator car 104 along the car guide rail 109A, and raise and lower the counterweight 105 along the counterweight guide rail 109B. That is, the guide rail 109 described in Figure 1 includes a pair of car guide rails 109A that guide the elevator car 104, and a pair of counterweight guide rails 109B that guide the counterweight 105.

[0025] The elevator car guide rail 109A includes an elevator car guide rail 109Aa positioned on one side of the elevator car 104 in the width direction (x-axis direction) of the elevator car 104, and an elevator car guide rail 109Ab positioned on the other side of the elevator car 104 in the width direction (x-axis direction) of the elevator car 104, with the elevator car 104 positioned between the elevator car guide rail 109Aa and the elevator car guide rail 109Ab. The counterweight guide rail 109B includes a counterweight guide rail 109Ba positioned on one side of the counterweight 105 in the depth direction (y-axis direction) of the elevator car 104, and a counterweight guide rail 109Bb positioned on the other side of the counterweight 105 in the depth direction (Y-axis direction) of the elevator car 104, with the counterweight 105 positioned between the counterweight guide rail 109Ba and the counterweight guide rail 109Bb.

[0026] One car guide rail 109Aa and one counterweight guide rail 109Ba are fixed to the hoistway wall HW1 by a shared rail bracket 108A, which is shared by both the car guide rail 109Aa and the counterweight guide rail 109Ba. The other car guide rail 109Ab is fixed to the hoistway wall HW1 by a car rail bracket 108B. The other counterweight guide rail 109Bb is fixed to the hoistway wall HW1 by a counterweight rail bracket 108C.

[0027] A pair of counterweight guide rails 109B and one of the car guide rails 109Aa are positioned in the space between one side 104d1 of the elevator car 104 and the hoistway wall HW1. In this embodiment, the side 104d1 of the elevator car 104 is the side facing the hoistway wall HW1 where the hoisting machine 102 is installed, and is the left side (left side) when viewed from the elevator hall 112 towards the elevator car 104. The shared rail bracket 108A is fixed to the hoistway wall HW1 facing the left side 104d1 of the elevator car 104 when viewed from the elevator hall 112. The counterweight rail bracket 108C is fixed to the hoistway wall HW1 facing the rear 104d2 of the elevator car 104. The car rail bracket 108B is fixed to the hoistway wall HW1 facing the right side (right side) 104d3 of the elevator car 104, as viewed from the elevator hall 112. The arrangement of the pair of counterweight guide rails 109B and the pair of car guide rails 109A is not limited to the arrangement described above.

[0028] The elevator device 100 described above is just one example of an elevator device to which the present invention applies, and other forms of elevator devices may also be used, and some of their configurations may differ from those described above.

[0029] In the following explanation, when it is not necessary to distinguish between the cage guide rail 109A and the counterweight guide rail 109B, they will simply be referred to as guide rail 109.

[0030] Next, with reference to Figures 3 and 4, the lighting device 10 installed in the ceiling section 104c will be described.

[0031] Figure 3 is a cross-sectional view parallel to the vertical direction of a lighting device 10 according to one embodiment of the present invention. The elevator system 100 is equipped with a lighting device 10 on the ceiling portion 104c of the elevator car 104. The ceiling portion 104c of the elevator car 104 is equipped with a reinforcing member 11 to ensure its strength and a flat cover 12 fixed to the reinforcing member 11 to serve as a platform for workers. An ornamental surface 104e is provided on the inner surface of the ceiling portion 104c, and the ornamental surface 104e constitutes the ceiling surface of the interior space 104f. The flat cover 12 is fixed to the reinforcing member 11 by bolts 21a and nuts 21b. The bolts 21a and nuts 21b serve as fastening members 21 that fix the flat cover 12 to the reinforcing member 11.

[0032] The lighting device 10 includes light sources 13a1 and 13a2 and a cover member 14. In this embodiment, the light sources 13a1 and 13a2 are composed of LEDs. The light sources 13a1 and 13a2, each composed of multiple LEDs, are provided on a single light source plate 13b. The light source plate 13b is fixed to the reinforcing member 11 by bolts 22. The bolts 22 are screwed into threaded portions (not shown) formed in the reinforcing member 11. The bolts 22 serve as fastening members that fix the light source plate 13b to the reinforcing member 11. Nuts (not shown) could also be screwed onto the bolts 22, but the number of parts can be reduced by forming threaded portions in the reinforcing member 11.

[0033] The cover member 14 is made of a light-transmitting material and is positioned below the light sources 13a1 and 13a2. In this case, the cover member 14 does not need to transmit all of the irradiated light; it is sufficient for at least a portion of the irradiated light to pass through and reach the interior space 104f of the elevator car 104.

[0034] In the lighting device 10, an internal space 15 of the lighting device is formed, enclosed by a reinforcing member 11, a flat cover 12a, and a cover member 14. The cover member 14 has a transmissive region 14a that delivers transmitted light to the interior space 104f of the elevator car 104. In this embodiment, the transmissive region 14a is formed by an opening 104e1 formed in the design surface 104e. The transmissive region 14a may also be formed by providing an edge portion (not shown) that does not transmit light to the cover member 14, and its form is not limited to that described in this embodiment.

[0035] The lighting device 10 of this embodiment includes an internal lighting device space 15 surrounded by a reinforcing member 11, a flat cover 12a, and a cover member 14, and a light source plate 13b on which a plurality of light sources 13a1, 13a2 are provided. The light source plate 13b is fixed to the reinforcing member 11 such that the light sources 13a1, 13a2 are located in the internal lighting device space 15. The light source plate 13b is placed on each of the two reinforcing members 11 located at both ends of the internal lighting device space 15 in the horizontal direction, and light is irradiated from the plurality of light source plates 13b toward the center of the internal lighting device space 15. A plurality of light sources 13a1, 13a2 are provided on one light source plate 13b. The light sources 13a1, 13a2 are positioned outside the transparent area 14a of the cover member 14 in the horizontal direction, and are positioned so that the irradiated light passes through the transparent area 14a indirectly or directly. In Figure 3, the light source plate 13b is positioned outside the outer edge of the transparent region 14a, with a gap d1 between them.

[0036] A single light source plate 13b has multiple light sources 13a1, 13a2 that emit light in at least two directions. Light source 13a1 emits light from outside the transparent region 14a toward a flat cover 12 positioned above the light sources 13a1, 13a2. The flat cover 12 is configured as a reflective member and has the function of reflecting light. Light emitted by the flat cover 12 is reflected by the flat cover 12 and passes through the transparent region 14a. At this time, the length of the irradiation path (optical path, P1 + P2) that the light emitted from light source 13a1 travels to the transparent region 14a of the cover member 14 (optical path length) is longer than the vertical distance L1 between the flat cover 12 and the cover member 14. As a result, the light emitted from light source 13a1 becomes more easily diffused due to the longer irradiation path.

[0037] Meanwhile, a light source 13a2, separate from light source 13a1, irradiates light from outside the transparent region 14a toward the flat cover 12 positioned below the light sources 13a1 and 13a2. In this case, light source 13a2 is positioned so that the light irradiated onto the transparent region 14a of the cover member 14 passes through the cover member 14 and reaches the interior space 104f of the elevator car 104. Light source 13a2 directly irradiates light toward the flat cover 12.

[0038] The light source 13a2 illuminates the flat cover 12 at an angle from outside the transparent region 14a. Therefore, the length of the illumination path (optical path) P3 that the light emitted from the light source 13a2 travels to the transparent region 14a of the cover member 14 is longer than the vertical distance L1 between the flat cover 12 and the cover member 14. As a result, the light emitted from the light source 13a2 becomes more easily diffused due to the longer illumination path.

[0039] In this embodiment, the flat cover 12 and the reinforcing member 11 are configured as reflective members and have the function of reflecting light. The flat cover 12 is a reflective member positioned above the light sources 13a1 and 13a2. The reinforcing member 11 is a reflective member that constitutes the side wall of the internal space 15 of the lighting device. Therefore, it is expected that the light irradiated from the light sources 13a1 and 13a2 will be diffused and reflected by the surrounding reflective members, thereby further diffusing. Furthermore, when the flat cover 12 and the reinforcing member 11 are configured as reflective members, both members 11 and 12 constitute a part of the lighting device 10. In this case, the lighting device 10 includes the flat cover 12a and the reinforcing member 11.

[0040] If either of the light sources 13a1 or 13a2 can illuminate the entire surface of the transparent area 14a with sufficient light, it is not necessary to provide the other light source. Alternatively, if it is possible to illuminate the entire surface of the transparent area 14a with sufficient light, light source 13a1 may be placed on one light source plate 13b and light source 13a2 on the other light source plate 13b.

[0041] The electrical wiring 13c of the light sources 13a1 and 13a2 is routed to the reinforcing member 11 and is pulled out to the outside of the ceiling portion 104c from the flat cover 12b other than the flat cover 12a that constitutes the internal space 15 of the lighting device. In other words, the electrical wiring 13c of the light sources 13a1 and 13a2 is not routed to the flat cover 12a that constitutes the internal space 15 of the lighting device. This eliminates the need to remove the electrical wiring 13c from the flat cover 12a that constitutes the lighting device when replacing the light sources 13a1 and 13a2.

[0042] Furthermore, as shown in Figure 3, the electrical wiring 13c is routed through the gap formed between the reinforcing member 11 and the flat cover 12 to the power box 16 (see Figure 4) located on the outside (upper side) of the ceiling portion 104c.

[0043] Figure 4 is a perspective view of the ceiling portion 104c of a train car 104 according to one embodiment of the present invention, viewed from diagonally above. The upper surface of the ceiling section 104c of the elevator car 104 is covered with a flat cover 12, which serves as a platform for workers.

[0044] The flat cover 12 is divided into multiple flat covers 12a and 12b, consisting of a flat cover 12a that covers the upper part of the lighting device's internal space 15 and the remaining flat covers 12b. In Figure 4, the flat cover 12a that covers the upper part of the lighting device's internal space 15 is omitted from the illustration.

[0045] As explained in Figure 3, the electrical wiring 13c, which is routed through the gap formed between the reinforcing member 11 and the flat cover 12, is pulled out to the outside (upper side) of the ceiling portion 104c through an opening 17 provided in the flat cover 12b near the power box 16 and connected to the power box 16.

[0046] Figure 5 is a cross-sectional view parallel to the vertical direction showing a modified example of the lighting device 10 according to the present invention. In this example, the electrical wiring 13c is drawn out to the outside of the lighting device 10 through an opening (through hole) 11a provided in the reinforcing member 11, and is wired near the power supply box 16 through the space between the reinforcing member 11 outside the lighting device 10 and the flat cover 12b. The configurations other than the configuration related to the wiring of the electrical wiring 13c are the same as those in the above-described embodiment.

[0047] Also in this example, the electrical wiring 13c is wired to the reinforcing member 11, is not wired to the flat cover 12a that constitutes the interior space 15 of the lighting device, and is drawn out from the flat cover 12b to the outside of the ceiling portion 104c. Thereby, also in this example, the replacement of the light sources 13a1 and 13a2 becomes easy.

[0048] Next, referring to FIGS. 6 and 7, the operation and effects of the lighting device 10 according to the present embodiment will be described. FIG. 6 is a cross-sectional view parallel to the vertical direction of a lighting device 10' according to a comparative example with the present invention. FIG. 7 is an explanatory diagram for explaining problems in the lighting device 10' shown in FIG. 6.

[0049] As shown in FIG. 6, when a light source plate 13b provided with a plurality of light sources 13a is provided on the flat cover 12a and the light from the light sources 13a is irradiated downward from above, it is necessary to make the distance (distance) L2 between the light sources 13a and the cover member 14 sufficiently large. If the distance (distance) L2 from the light sources 13a to the cover member 14 is made L2' (L2' < L2) as shown in FIG. 7, the light is not sufficiently diffused before reaching the cover member 14, and the outline of the light sources 13a becomes conspicuous on the cover member 14.

[0050] Further, when the distance (distance) L2 from the light sources 13a to the cover member 14 is increased as shown in FIG. 6, there is a problem that the thickness dimensions of the lighting device 10' and the ceiling portion 104c increase.

[0051] In the present embodiment, without increasing the thickness dimensions of the lighting device 10 and the ceiling portion 104c, the outline of the light sources 13a can be made inconspicuous on the cover member 14.

[0052] The elevator device 100 of the above-described embodiment has the following features. (1) In an elevator system 100 equipped with a lighting device 10 on the ceiling portion 104c of the elevator car 104, The lighting device 10 comprises light sources 13a1 and 13a2, and a cover member 14 positioned below the light sources 13a1 and 13a2, which transmits light and delivers it to the interior space 104f of the elevator car 104. The cover member 14 has a transparent region 14a that delivers transmitted light to the interior space 104f of the elevator car 104. The light sources 13a1 and 13a2 are positioned horizontally on the outside of the transparent region 14a of the cover member 14, and are arranged so that the irradiated light passes through the transparent region 14a.

[0053] (2) The lighting device 10 is equipped with reflective members 11 and 12 that reflect light irradiated from light sources 13a1 and 13a2, The light sources 13a1 and 13a2 are positioned so that the light irradiated onto the reflective members 11 and 12 passes indirectly or directly through the cover member 14 and reaches the interior space 104f of the elevator car 104.

[0054] (3) The reflective members 11 and 12 are positioned above the light sources 13a1 and 13a2.

[0055] (4) A light source 13a2 is provided, which is separate from the light source 13a1. Another light source 13a2 is positioned so that the light irradiated onto the transparent area 14a of the cover member 14 passes through the cover member 14 and reaches the interior space 104f of the elevator car 104.

[0056] (5) The light source 13a2 is positioned such that the light irradiated onto the transparent area 14a of the cover member 14 passes through the cover member 14 and reaches the interior space 104f of the elevator car 104.

[0057] (6) The elevator car 104 includes a reinforcing member 11 that ensures the strength of the ceiling portion 104c, and a flat cover 12 (12a, 12b) that is fixed to the reinforcing member 11 and serves as a platform for workers. The lighting device 10 includes an internal space 15 enclosed by a reinforcing member 11, a flat cover 12a, and a cover member 14, and a light source plate 13b on which a plurality of light sources 13a1, 13a2 are provided. The light source plate 13b is fixed to the reinforcing member 11 such that the light sources 13a1 and 13a2 are located in the internal space 15 of the lighting device.

[0058] (7) The flat cover 12 that serves as a platform for workers is divided into multiple sections. The electrical wiring 13c of the light sources 13a1 and 13a2 is routed to the reinforcing member 11 and is pulled out to the outside of the ceiling portion 104c from the flat cover 12b other than the flat cover 12a that constitutes the internal space 15 of the lighting device.

[0059] (8) The elevator car 104 includes a reinforcing member 11 that ensures the strength of the ceiling portion 104c, and a flat cover 12 (12a, 12b) that is fixed to the reinforcing member 11 and serves as a platform for workers.
