The present invention relates to an elevator cage interior lighting device installed on the ceiling of an elevator cage.

An interior lighting device of a conventional elevator cage is shown in FIG. In the drawings, reference numeral 1 denotes an elevator cage, 2 a side plate 3 of a cage 1, an entrance and exit of a cage 1, and 4 a ceiling of a cage 1. The lighting device 5 is provided on the ceiling 4 of the cage 1.

The lighting device (5) is composed of a lighting fixture (6), lighting frame (7) and lighting panel (8). The luminaire 6 is generally a fluorescent lamp, and a plurality of luminaires are provided on the lower surface of the ceiling 4 of the cage 1 at suitable intervals.

The lighting frame 7 includes a hanging member 7a which hangs from the lower surface of the ceiling 4 in a state surrounding the back 6 and a center of the lower end of the hanging member 7a. A frame member 7b which is installed in and supports the frame member 7b for dividing the lower openings of the suspension members 7a into a matrix, and the frame member 7b and covers the side openings of the suspension member 7a, respectively. It consists of the member 7c. The frame member 7b is horizontally installed below the luminaire 6 to form a plurality of openings between the hanging members 7a.

The lighting panel 8 is made of a transparent plate such as an acrylic resin plate having a pattern and design by silk screen printing or the like.

The panel 8 is provided on the frame member 7b on the flange of the suspension members 7a so as to cover each opening of the matrix frame member 7b therefrom, respectively.

However, the conventional elevator cage indoor lighting device 5 has the following problems.

That is, since the lighting panels 8 are fixed to the suspension and the frame members 7a and 7b, a professional worker must change the panel 8, so that a general user changes the panel 8, and so on. It is impossible to change the atmosphere in the room. For example, if the design of the panel 8 or the like is not changed, and if the interior of the cage 1 is too bright or too dark, the brightness of the interior of the cage 1 is appropriately adjusted. The first object of the present invention is to provide a lighting device that can adjust the brightness in the elevator cage by appropriately increasing and decreasing the brightness of the lighting fixtures installed on the ceiling of the cage.

A second object of the present invention is to provide an illumination device capable of changing the atmosphere within the cage and the visual design of the ceiling by freely changing and adjusting brightness and brightness.

In order to achieve these objects, a lighting device according to the present invention is a lighting device installed on the ceiling of an elevator cage, an illumination frame surrounding the lighting device and suspended on the ceiling, and having an opening at the bottom thereof, horizontally at the opening. And a blind having a plurality of slats having a variable inclination, and an operation mechanism for changing the inclination of the slats constituting the blind.

In the elevator cage indoor lighting device of such a configuration, the user of the elevator can set or tilt the inclination of the plurality of shading slats of the blind by operating an operation mechanism such as a cord of the blind. A part of the opening in the lower part of the frame can be opened and closed, and thus the degree of illumination in the elevator cage can be adjusted. Therefore, when the lighting panel is provided at the bottom of the frame, the design of the panel can be visually changed to change the brightness in the elevator cage. As a result, the atmosphere in an elevator cage can be easily changed suitably.

Since the present invention is composed of the lighting device as described above, the elevator user can simply change the lighting appropriately through the lighting panel, thereby changing the visual design of the cage, it can increase or decrease the degree of illumination in the cage, The invention has the effect of easily changing the atmosphere in the cage.

A first embodiment of the present invention will be described with reference to FIGS. The illuminating device 15 of this first embodiment has an elevator cage 1, a side plate 2, a doorway 3, a ceiling 4 of the cage 1, and the like having the same configuration as the conventional device shown in FIG. Has

The lighting device 15 is installed on the ceiling 4 of the cage 1, the lighting fixture 16, the lighting frame 17, the lighting panel 18, the upper protective panel 19 and the blind 20 It consists of.

The luminaire 16 uses several of the same fluorescent lamps as the conventional apparatus.

As in the conventional apparatus, the luminaire 16 is provided at regular intervals on the lower surface of the ceiling 4 of the cage 1.

As shown in detail in FIG. 5, the lighting frame 17 includes hanging members 17a suspended from the lower surface of the ceiling 4 while surrounding the lighting fixture 16, and the hanging members 17a. It consists of a lower frame member 17b provided at the lower end and a matrix-shaped intermediate end frame member 17c positioned slightly higher than the lower frame member 17b. That is, the frame members 17b and 17c constitute a double suspension ceiling. Each of the two hanging members 17a, which are opposed to each other, includes a top flange 17 _a1 and a bottom flange 17 _a2 , and these flanges are bent outwardly. The two pairs of suspended members 17a opposed to each other have upper flanges 17 _a1 and lower bent portions 17 _a3 , respectively, and the upper flanges 17 _a1 are bent outwardly, The lower bent portion 17 _a3 is bent inward.

The middle and lower frame members 17b and 17c are horizontally supported under the luminaire 16. Each of the members 17b and 17c has a plurality of beam portions and a portion that intersects the plurality of openings 21A to 21B, as shown in FIG. Parallel to each other.

The lighting panels 18 are transparent and consist of an acrylic resin substrate having a pattern and design by silk screen printing. The panels 18 are placed on the intermediate frame member 17c of the illumination frame 17 so that each of them covers each of the openings 21A, 21B of the matrix of the frame member 17c from above.

The surface protection panels 19 are made of a transparent glass plate. These panels 19 are placed on the lower frame member 17b of the illumination frame 17 to cover the respective openings 21A, 21B of the matrix of the frame member 17b from above.

As shown in Fig. 7, the blind 20 has the same configuration as the shutter-type light-blind blind (Venetian (blind)) commonly used for windows for shading or shading. 20 is a plurality of slats (shielding plate) 20a having a light-shielding property arranged at equal intervals and a rudder for fixing the slats (20a) in the left, right, top, bottom to adjust the inclination angle A string 20b is provided.

In this embodiment, two blinds 20 are provided between the frame members 17b and 17c, and these blinds 20 are each arranged in parallel with each other and perpendicular to the openings 21A and 21B. It is. That is, the blinds 20 are arranged at the left and right sides when viewed from the entrance 3 side to open and close the lighting panels 18. In addition, surface protection panels 19 such as a glass plate prevent the left and right blinds 20 from falling through the openings 21A and 21B.

Each of the blinds 20 includes an operation mechanism 22 including a rudder string 20b for changing the inclination angle of the light blocking slat 20a. This operation mechanism 22 is provided in the rear wall of the hanging member 17a of the said illumination frame 17 so that a user may operate manually. An extension of the operating mechanism 22 is located _{behind the} lower flange 17 _a2 to prevent the flange 17 _a2 from damaging the aesthetics of the cage 1.

As shown in FIG. 7, the operation mechanism 22 tightens and secures the ends of the casing box 22a and the rudder string 20b fixed to the side wall of the suspension member 17a, and the inclination angle of the slats 20a. The adjusting plate 22b for adjusting the pressure and the shaft 22c fixed to the adjusting plate 22b and rotatably supporting the adjusting plate 22b are provided on both side walls of the box 22a to support the shaft 22c. Two bearings 22d and a grip 22e for changing the inclination angle of the adjustment plate 22b to adjust the inclination angle are provided.

The operating mechanism 22 is rotatably attached to the hexagonal fixture 22f provided at the opposite end of the end on which the handle 22e of the shaft 22c is provided, and the shaft 22c rotates. It is further provided with the clutch rod 22g for fixing so that it may be fixed. The fixing portion 22f and the clutch rod 22g constitute a stopper for fixing the adjusting plate 22b at a predetermined inclination angle.

In the elevator cage indoor lighting device having the above configuration, the user simply operates the operation mechanism 22 of the blind 20 to tilt or raise the plurality of slats 20a to simplify the inclination angle of the blind 20. In other words, it is possible to allow the left and right illumination panels 18 to be covered or opened by the light blocking slats 20a.

Since it is possible to change the appearance of these lighting panels 18 to increase or decrease the intensity of light in the cage 1 irradiated by the lighting fixture 16, the atmosphere in the cage can be simply changed appropriately.

As will be described later, when the user rotates the knob 22e of the operating mechanism 22 only in one direction of the left side, for example, the plurality of slats 20a are inclined, so that the lids of the two adjacent slats overlap each other to open the openings. The fields 21A and 21B are completely closed. Inclined slats 20a block light from the luminaire 16.

Therefore, the ceiling appearance can be used as a light shielding plate, and the dark room atmosphere can be made by reducing the brightness.

On the contrary, when the handle 22e fixed to the adjusting plate 22b is turned in the opposite direction to the direction, that is, in the right direction, all the slats 20a are erected to create a space between these upright slats. If you look at the ceiling through this space, you can see the design printed on the panels 18, thus obtaining a different louver appearance. Therefore, the light of the luminaire 16 passes through the spaces and the transparent panels 18 and is introduced into the cage 10 to illuminate the interior.

The blinds 20 can be erected or tilted completely for each blind or both blinds together. Therefore, the design and lighting position can be changed in various ways. The blind 2 may block the light by selecting the inclination angle of the slat 20a to appropriately adjust the intensity of the light passing through the panels 18.

Therefore, even if the inside of the cage 1 is too bright or dark under the influence of the painting of the wall of the cage 1, the intensity of light can be easily adjusted to the optimum state. In addition, the user can brighten the inside of the cage during the day and use it as an office elevator, and at night, the cage can be darkened and used as a restaurant elevator in a romantic atmosphere, and the elevator cage can be used easily and sufficiently. It is useful to completely open all the slats 20a of the blinds 20 when the cage is cleaned.

In the first embodiment, two openings 21A and 21B are provided in the frame members 17b and 17c, respectively, but the present invention is not limited to this configuration. For example, the illuminating device of the second embodiment has four openings 21A to 21D and two small blinds 20 provided in the openings 21C and 21D, as shown in FIG. have.

It is. Each of the openings 21A, 21B, 21C, and 21D includes an illumination panel 18 and a protection panel 19, respectively. As shown in FIG. 8, the star-shaped chair 23 and the information guide display 24 of each floor, for example, "2nd floor toy", are displayed on the lighting panel 18. As shown in FIG. In the second embodiment, the frame members 17b and 17c have a matrix shape different from that of the first embodiment, and two blinds 20 are disposed on both sides corresponding to the openings 21C and 21D. It is characteristic.

Therefore, all the slats are erected during the day, guide information can be seen by looking at the cage (1) ceiling.

On the contrary, when it is necessary to reduce the intensity of light at night, the chairman 23 and the guide display 24 are covered by closing all the slats as shown by the administrator on the left side of FIG. As a result, customers can see whether the floor is open or closed.

The chair 23 and the guide 24 are drawn on the illumination panel 18, but this information 23, 24 is applied to the slats 20a of the blind 20 irrespective of the panel 18. You can also draw. Thus, in contrast to the second embodiment, the user can recognize the information 23, 24 when the blind 20 is closed.

The blind 20 is arranged with the corresponding panel 18 from the lower surface of the panels 18 of the left and right openings 21C and 21D, although the device of the present invention is provided with these openings 21A and 21B. It may be provided with blinds 20 corresponding to.

In addition, all of the openings 21A to 21D may be covered with the blinds 20. In addition, the blind 20 may be disposed on the lighting panels 18 to obtain the same effects as the first and second embodiments. In this case, the surface protection panels 19 become unnecessary.

In addition, although the first and second embodiments do not include an expansion mechanism, the device of the present invention is an expansion mechanism (not shown) having the same configuration as the expansion mechanism having a lifting rope for raising and lowering a normal venetian blind. It can be provided, whereby, in addition to changing the inclination angle of the slats, these slats can be folded to one side of the illumination frame 17.

Although the first and second embodiments of the present invention each have a telescopic mechanism such as the hoisting rope, the present invention is not limited to the above configuration.

For example, the stretching mechanism according to the third embodiment may be applied to hold the slats of the blind.

The other configuration of this third embodiment is the same as that of the first or second embodiment shown in Figs.

In FIG. 9, the expansion mechanism 30 is equipped with an inclination angle operation mechanism on one side, and the other side is disposed opposite and the rudder strings for supporting the slats 20a between the two suspension members 17a. A sliding rod 31 for holding and supporting two guide reels 25 for hanging 20b; A toothed belt 32 having a toothed portion 32a on one side and fixed at one point to the sliding rod 31; Guide rails (33) for fitting engaging portions (31a) provided at both ends of the sliding rod (31) to support both ends of the sliding rod (31) to be slidable; A reel (34) having a shaft (34a) and a pinion (34b) for supporting another point of the toothed belt (32) and rotating the toothed belt (32) with the pinion (34b); A small motor (35) installed at one end of the shaft (34a) and having an output shaft rotating the reel (34) with the shaft (34a); A support stand 36 is provided to support the reel 34 and the motor 35 and includes a drive ON / OFF switch 37 of the motor 35 and a rotation direction switch. The toothed belt 32 is a pinion of the support pinion 39 and the shaft 34 disposed between the suspension member 17a and the sliding rod 31 on the side not shown in FIG. It is caught between the on 34b. This toothed belt is engaged with the pinion 39 as shown in detail in FIG.

According to the above configuration, when the rotation direction switching switch 38 is switched to the folding side W and the ON / OFF switch 37 is turned on, the motor 35 starts to rotate in the normal direction, Since the toothed belt 32 is rotated, the rod 31 fixed to the belt slides along the guide rail 33 in the direction of the folding mechanism 30. On the contrary, when it is necessary to spread the slats 20a of the blinds 20 over the entire length of the belt, the direction switching switch 38 is set to the unfolding side R, and the switch 37 is turned ON. When the motor 35 is rotated in a direction opposite to the folding direction, the sliding rod 31 is moved to a position immediately before the other suspension member 17a (not shown).

As a result, the slats 20a can be uniformly spread at equal intervals in the section between the pinions 34b and 39.

Other operations such as adjustment of the slat inclination angle are substantially the same as those of the first and second embodiments, and thus redundant description is omitted.
