Description

[Technical Field]

[0001] The present invention relates to an elevator, and more particularly to an elevator having a function of illuminating the interior space of an elevator car. [Background technology]

[0002] Elevator cars are equipped with lighting devices (lighting units) that illuminate the interior space of the car. Some lighting devices are configured, for example, by installing a light source behind an acrylic plate installed in the ceiling of the car, and illuminating the interior space of the car (hereinafter referred to as the "interior space of the car") by transmitting light from the light source through the acrylic plate.

[0003] In addition, some elevators illuminate the interior space of the car by irradiating light from a light source onto a reflector or the like, and using the light reflected by the reflector (hereinafter referred to as "indirect light") as illumination.

[0004] For example, Patent Document 1 discloses an elevator equipped with a lighting unit in which a curved reflector is installed in an opening provided at the end portion of a suspended ceiling, and light from a light source installed on the upper surface of the suspended ceiling is reflected by the reflector to illuminate the space inside the car directly below.

DETAILED DESCRIPTION OF THE INVENTION

[0013] An elevator 10 to which a car according to one embodiment of the present invention is applied will be described below with reference to the drawings. In each drawing, "X" indicates the horizontal direction substantially perpendicular to the axial direction of the sheave 18A, "Y" indicates the horizontal direction Y perpendicular to the horizontal direction X, and "Z" indicates the vertical direction Z perpendicular to the horizontal directions X and Y, respectively.

[0014] Fig. 1 is a diagram showing the schematic configuration of an elevator 10. As shown in Fig. 1, the elevator 10 is a traction rope elevator, and includes a car 20 suspended from one end of a main rope 12 and a counterweight 15 suspended from the other end of the main rope 12.

[0015] The main rope 12 is stretched over a sheave 18A and a deflector sheave 18B of a hoisting machine 18 installed in a machine room M directly above the elevator shaft 17, and has the function of relatively raising and lowering the car 20 and the counterweight 15 by rotating the sheave 18A forward or backward using a hoisting machine motor (not shown). The car 20 has a generally vertically long box shape and includes a floor panel FL that is generally rectangular in plan view and that constitutes the car floor surface, side wall panels SP1, SP2, SP3, and SP4 (hereinafter referred to as "side wall panels SP" as appropriate) (see Figure 2) that are erected so as to surround the periphery of the floor panel FL, a ceiling panel UP that covers the top surface of the car 20, and a ceiling lighting unit 30 attached directly below the ceiling panel UP of the car 20.

[0016] Fig. 2 is a perspective view showing the configuration of the ceiling lighting unit 30 attached to the ceiling panel UP of the car 20. Fig. 3 is a diagram showing the configuration when the central part of the ceiling lighting unit 30 shown in Fig. 2 is cut along a plane parallel to the XZ plane. In Fig. 3, cross-sectional hatching is omitted to avoid cumbersome illustration.

[0017] As shown in Figures 2 and 3, the ceiling lighting unit 30 includes six blade units 32A, 32B, 32C, etc. (hereinafter referred to as "blade units 32" wherever necessary unless a distinction is required) that are long plates when viewed from below and are arranged at predetermined intervals, and five reflective sheets (flexible sheets) SH1, SH2, SH3, etc. (hereinafter referred to as "reflective sheets SH" wherever necessary unless a distinction is required) that are each held and fixed in a curved state between each blade unit 32, and is equipped with a device main body 34 which is a support frame body connected and fixed to the ceiling panel UP.

[0018] The ceiling lighting unit 30 is an indirect lighting device that illuminates the interior space of the elevator car 20 with indirect light generated when light emitted from each slat unit 32 is reflected by the reflective sheet SH. Here, indirect light refers to light that is emitted from a light source unit 39 (described later) and is reflected by an object such as the reflective sheet SH.

[0019] Since the configurations of each blade unit 32 and each reflection sheet SH are almost identical, the following description will use blade unit 32C and reflection sheet SH2 as an example. As shown in Fig. 3, blade unit 32C includes a blade main body 36 whose opposite ends are connected to side plates 34A, 34B attached to opposite ends of device main body 34, a light source unit 39 supported by blade main body 36 via fixed arms AR, and a support bracket 38 that fixes reflection sheet SH2.

[0020] The slat body 36 has a generally U-shaped cross section and is arranged so as to appear as a long, rounded rod when viewed from below. The light source unit 39 is, for example, a long, rod-shaped LED (Light Emitting Diode) lamp or fluorescent lamp arranged in the longitudinal direction of the slat body 36, in other words, along the horizontal direction Y. As shown in FIG. 3 , the light source unit 39, the fixed arm AR, the clamp 38A, the support bracket 38, and the bolt BT are concealed and arranged on the rear side of the slat unit 32C, i.e., slightly toward the center of the upper surface, so as not to be visible when the slat unit 32C is viewed from below. This arrangement provides a clean and tidy impression to passengers, as the light source unit 39, the fixed arm AR, the clamp 38A, the support bracket 38, and the bolt BT are not visible to passengers when viewed from below.

[0021] 3, the fixed arm AR is a substantially C-shaped sheet metal member, one end of which is fixed to the rear end of the blade body 36, and the other end of which is connected and fixed to the light source unit 39. This allows the light source unit 39 to be installed in a position where it illuminates the reflective sheet SH2 from a diagonally downward direction. Note that in this embodiment, only the blade unit 32A located on the left end side is different from the other blade units 32 in that the light source unit 39 is not provided.

[0022] The reflective sheet SH2 is made of a flexible resin sheet such as a polypropylene sheet. In this embodiment, the reflective sheet SH is made of polypropylene, but other resin sheets, such as a vinyl chloride sheet, a nylon sheet, or an acrylic sheet, may also be used.

[0023] Furthermore, one end of the reflective sheet SH2 in the horizontal direction X, together with the end of the reflective sheet SH3 adjacent to it on the right, is sandwiched in the vertical direction Z between the press fitting 38A and the support bracket 38 and fixed via the bolt BT. Similarly, the other end of the reflective sheet SH2 is held and fixed together with the end of the reflective sheet SH1 adjacent to it on the left.

[0024] Here, the length of the reflection sheet SH in the X direction is formed to be longer than the distance L1 between the fixing positions of the reflection sheet SH in the blade units 32. Therefore, the reflection sheet SH is installed and held in a curved state that protrudes upward by connecting and fixing both ends in the X direction to the support brackets 38 of adjacent blade units 32. Also, as described above, the reflection sheet SH that is deformed and held in a curved state by fixing both ends to the support brackets 38 of each blade unit 32 has a large proportion of deformation due to elastic deformation, so it has the advantage of being less likely to lose its curved shape and having excellent shape retention.

[0025] In the ceiling lighting unit 30 of this embodiment, an example in which six vane units 32 are arranged at predetermined intervals has been described, but the present invention is not limited to this. For example, if the dimension of the car 20 in the X direction is longer, seven or more vane units 32 may be arranged at predetermined intervals. This makes it possible to obtain the same effect as the elevator 10 in the above embodiment even when the length of the car 20 in the X direction is longer.

[0026] Furthermore, when the dimension of the car 20 in the X direction is shorter, five or fewer vane units 32 may be arranged at predetermined intervals. This allows the same effect as the elevator 10 in the above embodiment to be obtained even when the length of the car 20 in the X direction is shorter.

[0027] Furthermore, in the ceiling lighting unit 30 of this embodiment, an example has been described in which the plurality of blade units 32 are arranged at equal intervals, but the blade units 32 do not necessarily have to be spaced at equal intervals, and the blade units 32 may be spaced at different distances from one another. Even in this case, the same effects as those of the elevator 10 of the above embodiment can be obtained.

[0028] According to the elevator 10 of this embodiment, the interior space of the car can be illuminated using light reflected by the reflective sheet SH, i.e., indirect light, which allows the weight of the ceiling lighting unit 30 to be reduced compared to when a metallic reflective member such as a metal sheet is used.

[0029] Next, a first modified example and a second modified example of the ceiling lighting unit 30 will be described with reference to Figures 4(a) and 4(b). In Figures 4(a) and 4(b) and the following description, the same components as those of the ceiling lighting unit 30 according to the above embodiment will be denoted by the same reference numerals as appropriate, and a description will be omitted, with the focus being on the different components.

[0030] 4(a), the ceiling lighting unit 40 according to the first modification has the same configuration as the ceiling lighting unit 30 according to the above embodiment, except that it is provided with restricting members 42A, 42B, 42C, ... (hereinafter, when no particular distinction is required, they will be referred to as "restricting members 42") that restrict the curved position of the reflective sheet SH. The restricting members 42 are, for example, long cylindrical members, and are installed between the side plates 34A and 34B (see FIG. 2) so as to abut against the upper surface of the reflective sheet SH that is held in a curved state.

[0031] This allows the curvature of the reflecting sheet SH in the horizontal direction X to be locally and largely changed. As a result, it is possible to locally and largely change the brightness of the reflected light that is generated when light emitted from the light source unit 39 is reflected by the reflecting sheet SH. In this case, too, it is possible to obtain the same effect as that of the ceiling lighting unit 30 according to the above embodiment.

[0032] As shown in FIG. 4(b), the ceiling lighting unit 50 according to the second modification differs from the ceiling lighting unit 30 according to the above embodiment in that it includes reflective (flexible) sheets SL1 and SL2 (hereinafter, referred to as "reflective sheets SL" as appropriate unless otherwise specified) that have the same configuration as the reflective sheet SH according to the above embodiment but are longer in the X direction than the reflective sheet SH, and three blade units 32A, 32B, and 32C. More specifically, the blade units 32A, 32B, and 32C are disposed at both ends and a central position of the device body 34 in the X direction. The dimension of the reflective sheet SL in the X direction is formed to be slightly longer than the distance L2 between the fixing positions of the reflective sheets SL on adjacent blade units 32A and 32B.

[0033] In this way, the spacing between the blade units 32 may be longer than that of the ceiling lighting unit 30 according to the above embodiment. In this case, the same effects as those of the ceiling lighting unit 30 according to the above embodiment can be obtained.

[0034] The present invention can be implemented in various forms, including improvements, modifications, and variations based on the knowledge of those skilled in the art, without departing from the spirit of the invention. Furthermore, the invention can be implemented in a form in which any of the features of the invention are replaced with other technology, as long as the same action or effect is achieved.
