JP-A-6-305665

  However, when the light source body is replaced in the leglight illumination device described in Patent Document 1, in order to open the bottom plate of the box attached to the lower side of the norikura floor, the work should be carried under the nodule. Will be done. Although the operation of changing the light source body itself can be performed in a horizontal position, the work of removing the bolts and nuts on the bottom plate is a posture in which the body is looked up or the body is inclined. Furthermore, at least the last one bolt must be removed while supporting the bottom plate so that the bottom plate does not open suddenly.

  Therefore, there is a possibility that the bolts, nuts or tools fixing the bottom plate may be dropped carelessly. In addition, if priority is given to performing work carefully in consideration of prevention of falling of articles, it is not expected to reduce the work time.

  In order to replace the light source body from the inside of the carriage, it is necessary to have a structure for fixing the floor plate that also serves as the light-transmitting plate so as to be opened. When a key, a hinge, or the like is provided as a structure for fixing the floor board so that it can be opened, the key or the hinge may be inevitably disposed at a position visible to the passenger. In such a case, the design is impaired, and a depression is generated around the key and the hinge, which may cause a passenger to crawl. In addition, if dust or sand collected in the depression bites into the key or hinge, it may be difficult to open the floorboard.

  Therefore, the present invention can easily replace the light source provided in the lighting fixture from the inside of the riding board, and is excellent in the design of the floor surface, the elevator including the same, and the floor lighting device Provide maintenance methods.

  The floor lighting device according to the present invention illuminates the interior of the elevator from the floor side, and includes a floor reinforcement, a lighting fixture, an inspection window, a fixed floor, a movable floor, a fixed member, and a slide mechanism. And at least one of the fixed floor material and the movable floor material is translucent. The floor reinforcement is arranged in a grid pattern on the norikura floor to form a plurality of cells. The luminaire is installed inside at least one grid. The inspection window is opened in a bed apron that hangs down below the boarding gate. The fixed floor material covers the release mesh that communicates with the inspection window among the meshes. The movable floor material individually covers the cells other than the release cells. The fixing member is removably fixed to the floor reinforcement by being manually operated through the inspection window. The slide mechanism is disposed between the movable floor material and the floor reinforcing material, and supports the movable floor material so as to be movable along the floor reinforcing material. The locking mechanism prevents the movable floor material from floating with respect to the floor reinforcement.

  In this case, the slide mechanism includes a fixed side frame attached to the floor reinforcing material, a moving side frame attached to the edge of the movable floor material, and a plurality of pieces that are sandwiched between the fixed side frame and the moving side frame and are in contact with each other. Rolling elements, and individually corresponding to each of the movable flooring materials. Then, the slide mechanisms provided on the movable floor materials whose moving directions intersect each other are arranged at different heights from the upper surface of the movable floor material.

  Alternatively, the slide mechanism includes a rail laid along the floor reinforcing material, and a guide portion that is provided in a pair on the edge extending in parallel with the movable floor material and fits to the rail.

  Alternatively, the slide mechanism and the locking mechanism are preferably configured by a guide portion formed on the outer periphery of the movable floor material and a post attached to the intersection of the floor reinforcing material and engaged with the guide portion. In this case, the post located at the corner of the fixed floor facing the inspection window is provided with a notch that allows the corner of the fixed floor to pass toward the inside of the riding board.

  Or the upper surface of adjacent fixed flooring and movable flooring, and adjacent movable flooring is made mutually continuous. In this case, “continue to each other” means that the fixed members and the movable members that are adjacent to each other and the movable peripheral members that are adjacent to each other are arranged side by side so that there is no gap between them. Therefore, there may or may not be a slight gap prepared in advance based on the manufacturing intersection.

  Moreover, the part which has translucency among a fixed floor material and a movable floor material is formed with the composite material which combined any one of glass, an acrylic resin, and polycarbonate, or these at least two. The light source used for the lighting fixture is any one of a light bulb, a fluorescent lamp, a light emitting diode, or a combination of two or more of these.

  The elevator according to the present invention is provided with a saddle floor lighting device having the above-described configuration at the ride. Moreover, the maintenance method of the floor illuminating device according to the present invention is performed on the floor illuminating device having the above-described configuration, and the bed leaving operation, the releasing operation, the first opening operation, and the second opening. Operation. In getting out of bed, the platform is moved to a position where the lid of the inspection window can be opened from the landing side. In the release operation, the fixed member is operated through the inspection window to release the fixed floor material restrained with respect to the floor reinforcing material. In the first opening operation, the fixed flooring is removed to the inside of the riding board, and the release mesh is communicated with the inside of the riding board. In the second opening operation, the movable floor material is moved along the floor reinforcing material so that the cells other than the release cell communicate with the inside of the riding rod.

  According to the floor lighting device according to the present invention, when the fixed floor material is removed, the movable floor material is sequentially slid in a puzzle shape by the slide mechanism, and the cell covered under the movable floor material can be opened. Have. When replacing the light source of the luminaire during maintenance, the work can be facilitated from the inside of the riding board. Therefore, worker safety is ensured and workability is improved.

  An initial operation for opening each cell is performed from the inspection window 53. The inspection window 53 is opened in a bed apron which is not seen by passengers on board. The fixed floor material of the floor lighting device is fixed to the floor reinforcing material by a fixing member operated from the inspection window 53. The movable floor material is prevented from floating from the floor reinforcement by a locking mechanism. Thus, the fixed floor material and the movable floor material are fixed to the rider at a position not facing the rider's interior. That is, the fastener for fixing the fixed floor material and the movable floor material is not exposed on the floor surface. Therefore, there are no steps or depressions on the floor that cause passengers to crawl. Moreover, since there are no fasteners or the like on the floor surface, it is possible to prevent mischief, and it is excellent in terms of design inside the riding rod.

  According to the invention in which the slide mechanism is provided individually corresponding to the movable floor material, since each slide mechanism includes the rolling elements, the sliding resistance for moving the movable floor material is reduced. In addition, since the slide mechanisms provided on the movable floor materials whose movement directions intersect with each other are arranged at different heights, the movable floor materials can be moved without the slide mechanisms interfering with each other.

  Further, according to the invention in which the slide mechanism and the locking mechanism are configured by the rail laid on the floor reinforcing material and the guide portion that is provided on the edge of the movable floor material and is fitted to the rail, the movable mechanism can be moved with a simple structure. The floor material can be prevented from floating from the floor reinforcing material, and the desired floor can be opened by sliding the movable floor material.

  According to the invention in which the slide mechanism and the locking mechanism are constituted by a guide portion formed on the outer periphery of the movable floor material, and a post attached to the intersection of the floor reinforcing material and engaged with the guide portion, the individual movable floor material Can be moved in either of two orthogonal directions. That is, it is possible to open the cell with a few steps without being restricted by the moving direction of the movable floor material. Further, since the shape of the movable member is unified, it is only necessary to move the movable member so that the release cell is opened without returning to the original arrangement at the time of maintenance. Therefore, workability in maintenance is improved. Furthermore, it is also possible to move the dirty movable flooring to an inconspicuous position by changing the arrangement of the movable flooring.

  In addition, the floor lighting device in which at least one of the fixed floor material and the movable floor material has translucency can be used for a lighting effect by mixing a translucent material and a non-translucent material. Various design properties can be imparted. For example, the design can be changed to a different atmosphere by changing the arrangement of the movable members.

  As a material used for the light-transmitting portion, it is also preferable to use, in addition to glass, an acrylic resin, polycarbonate, or a composite material in which at least two of these are combined. When glass is used for flooring, it is less likely to be scratched than acrylic resin or polycarbonate. In addition, when an acrylic resin or polycarbonate is used, the fixed floor material and the movable floor material can be reduced in weight compared to glass, so that operability is improved in maintenance. Further, when laminated glass in which a polycarbonate sheet is sandwiched between glasses is used, even when the glass is cracked, scattering can be prevented.

  Moreover, the light source of a lighting fixture can be suitably selected according to the required lighting effect, such as a light bulb, a fluorescent lamp, and a light emitting diode. Two or more of these may be used in combination. Furthermore, the light source may illuminate an adjacent cell through a through hole or a notch provided in a floor reinforcing material that partitions adjacent cells. Further, the light source itself may be passed through the through-hole and disposed across the adjacent cells.

  The elevator according to the present invention can maintain the lighting device that illuminates the inside of the riding board from the inside of the riding board by including the floor lighting device having the above-described configuration. Further, since the slide mechanism and the locking mechanism are not exposed to the inside of the riding rod, it is excellent in terms of design and also prevents mischief.

  According to the maintenance method of a floor illuminating device according to the present invention, the floor illuminating device has the above-described configuration, so that it does not enter the hoistway under the boarding ridge, and the floor illuminating device is out of the platform. Maintenance of the lighting fixtures can be performed. Therefore, workability is good, and it is also preferable in terms of worker safety measures.

  The slide mechanism 20 includes a fixed side frame 21, a moving side frame 22, and a plurality of rolling elements 23. The fixed side frame 21 is attached to the floor reinforcing material 11, and the moving side frame 22 is fixed to the floor frame 101 of the movable floor material 14. The rolling elements 23 are sandwiched between the fixed side frame 21 and the moving side frame 22 and are in rolling contact with each other. The rolling elements 23 are maintained at regular intervals by a cage. The fixed side frame 21 and the moving side frame 22 are fitted to each other via the rolling elements 23, and also serve as a locking mechanism 30 that prevents the movable floor material 14 from floating from the floor reinforcing material 11. Yes.

  Next, a maintenance method for opening each cell 50 with respect to the inside of the riding rod 5 will be described with reference to FIGS. 6 to 9, taking as an example the case of replacing the fluorescent lamp 121 that is the light source of the lighting fixture 12. The maintenance method of the floor lighting device 10 includes a bed leaving operation S1, a release operation S2, a first opening operation S3, and a second opening operation S4.

  In the floor leaving operation S <b> 1, the platform 5 is moved by manual operation to a position higher than the landing floor so that the lid 54 of the inspection window 53 can be opened from the landing side. In the release operation S2, the bolts holding the lid 54 are removed, the lid 54 is opened, and a tool T such as a box wrench is inserted from the inspection window 53 as shown in FIG. 6, and the fixing bolt 151 is removed.

As a result, the release grid 501 communicates with the interior of the riding platform 5. In 2nd opening operation S4, as shown in FIG.8 and FIG.9, the movable flooring 14 is moved and the desired mesh 50 is opened.

  In FIG. 8, the movable floor material 14 of the DB adjacent to the left is moved to the release cell 501 that has been opened by removing the fixed floor material 13. Further, in FIG. 9, the movable floor material 14 of the CB adjacent to the upper side in the figure is moved to the grid 50 opened by moving the movable floor material 14 in the DB, and further, the movable floor material 14 in the CB is movable. The movable floor material 14 in the BB adjacent above is moved to the mesh 50 opened by moving the floor material 14.

  In addition, when the grid 50 covered by the AC movable flooring 14 is to be opened, the CC movable flooring 14 is moved to the released release grid 501 by removing the DC fixed flooring 13, and then sequentially BC , AC movable flooring 14 is moved to the lower cell 50. Further, when the grid 50 covered by the AA movable floor 14 is opened, the DB movable floor 14 is moved to the release grid 501, and then the movable floor 14 is moved as shown in FIG. The movable floor member 14 is moved like a puzzle in the order of DA, CA, BA, and AA in the grid 50 being processed.

  In this way, the movable flooring 14 is moved from the release grid 501 as a base point, and the grid 50 in which the lighting fixture 12 is disposed is opened in order, so that the lighting fixture 12 of the floor lighting device 10 is provided. The work of exchanging the fluorescent lamp 121 can be performed from the inside of the carriage 5. Moreover, the movable flooring 14 of the floor lighting device 10 in the first embodiment can move only in one direction by the slide mechanism 20 provided individually. That is, the grid 50 to which each movable flooring 14 corresponds is determined in advance and can be easily restored after the work is completed.

  In the present embodiment, the slide mechanism 20 moves the movable flooring 14 on the entrance 51 side in a direction crossing the entrance 51 and moves the remaining movable flooring 14 in the depth direction toward the entrance 51. The slide mechanism 20 moves the movable floor 14 with respect to one of the adjacent cells 50. It is sufficient that the slide mechanism 20 of the movable floor material 14 covering a certain mesh 50 does not interfere with the previous slide mechanism 20 that has moved the movable floor material 14. Therefore, regardless of only the arrangement of the slide mechanism 20 shown in FIG. 5, all the meshes 50 are opened in order by moving the movable floor material 14 sequentially in a single stroke with the release mesh 501 as a base point. In this way, the slide mechanism 20 may be arranged.

  A bed lighting device 10 according to a second embodiment of the present invention will be described with reference to FIGS. 10 to 14. The configuration having the same function as the configuration of the floor lighting device 10 described in the first embodiment is denoted by the same reference numeral, and the description thereof is omitted.

  The floor reinforcing material 11 of the floor lighting device 10 shown in FIG. 10 is assembled in a lattice shape using a square steel pipe. The hand hole 113 is provided so as to penetrate the floor reinforcing material 11 near the entrance 51. The slide mechanism 20 and the locking mechanism 30 are configured by a rail 16 laid along the floor reinforcing material 11 and a pair of guides 141 formed on edges extending in parallel with the movable floor material 14. The rail 16 and the guide 141 are engaged with each other to prevent the movable floor member 14 from being lifted with respect to the floor reinforcing member 11.

  In the present embodiment, the direction in which each movable floor member 14 moves is the same as the moving direction of the movable floor member 14 in the first embodiment. When the arrangement coordinates of the fixed floor material 13 and the movable floor material 14 are defined as in the first embodiment, the adjacent movable floor material 14 between DA and CA, DB and CB, DD and CD, and DA and DB, respectively. The edges 142 and 143, the edge 132 of the fixed flooring 13 adjacent between DC and CC, the edge 143 of the movable flooring 14, the edge 142 of the movable flooring 14 adjacent between DB and DC, and DD and DC The edge 133 of the fixed floor 13 is engaged so that the former is on the left side and the latter is on the right side in FIG.

  A guide 141 formed on the edge of the movable floor member 14 facing the outer periphery of the floor lighting device 10 is engaged with the rail 16 as shown in FIG. The movable floor member 14 arranged in CA, CB, CD is prevented from floating from the floor reinforcing member 11 by fitting to the rail 16 extending in the depth direction from the entrance 51. Therefore, the edge of the movable flooring 14 arranged in CA, CB, CD and arranged on the entrance 51 side functions as the slide mechanism 20 and the locking mechanism 30 of the movable flooring 14 arranged in DA, DB, DD. . Further, as shown in FIG. 12, the fixed floor member 13 and the movable floor member 14 are engaged between DC and CC, so that the edge of the movable floor member 14 serves as a fixed member for the fixed floor member 13. .

  As shown in FIG. 14, the edge of the fixed floor 13 located on the handhole 113 side has a screw hole 104 and is fastened and fixed by a fixing bolt 151. And the rail 16 is not arrange | positioned at the floor reinforcement material 11 of this area. Therefore, the movable floor member 14 moved to the release grid 501 is released from the engagement with the floor reinforcing material 11. Therefore, by inserting a hand or a dedicated jig from the hand hole 113 and pushing it up, the movable floor member 14 can be removed toward the inside of the riding board 5 similarly to the fixed floor member 13. FIG. 10 shows a state in which the movable floor material 14 of BC, BD, CB, CC, CD, DB, and DD is just removed.

  The slide mechanism 20 and the locking mechanism 30 of the floor lighting device 10 configured as described above have a simpler structure than those of the floor lighting device 10 described in the first embodiment. Moreover, since it is not necessary to arrange the slide mechanisms 20 of the movable floor member 14 whose movement directions intersect with each other at different heights, the bulk of the floor portion of the riding rod 5 can be reduced.

  Furthermore, the movable flooring 14 moved to the release grid 501 can be removed to the inside of the carriage 5 as necessary. Therefore, the work can be performed in a state in which several cells 50 are released at the same time, so that work efficiency is also improved. It is also possible to easily replace the movable flooring 14 that has deteriorated over time or has been damaged.

  A bed lighting device 10 according to a third embodiment of the present invention will be described with reference to FIGS. 15 to 17. Configurations having the same functions as those of the floor lighting device 10 according to the first embodiment or the floor lighting device 10 according to the second embodiment are denoted by the same reference numerals, and description thereof is omitted. Moreover, the arrangement | sequence of the fixed flooring 13 and the movable flooring 14 is demonstrated below as what is the same as the arrangement | sequence of 1st Embodiment.

  In the floor lighting device 10 shown in FIG. 15, the floor reinforcing material 11 constitutes a mesh 50 with lip groove steels assembled in a lattice shape. Posts 17 are arranged at the intersections of all the floor reinforcements 11. The post 17 has a rectangular body section 171 and a top section 172, and the top section 172 has a larger horizontal cross-sectional shape than the body section 171, and has a T-shaped vertical section as shown in FIGS. 16 and 17. The four sides of the post 17 are aligned in a direction parallel to the four sides of the fixed floor 13 and the movable floor 14.

  All the movable flooring materials 14 have the same shape, and a guide portion 18 is formed on the outer periphery of the floor frame 101 as shown in FIGS. The groove 181 of the guide portion 18 is fitted to the top portion 172 of the post 17 as shown in FIG. A lower portion 182 of the guide portion 18 is formed to have a size that comes into sliding contact with the body portion 171 of the post 17. Further, the fixed flooring 13 has the same shape as the movable flooring 14, and is fixed from the floor reinforcing material 11 to the floor frame 101 on the side facing the handhole 113 as shown in FIG. A screw hole 104 into which the bolt 151 is screwed is provided. In the present embodiment, the guide portion 18 and the post 17 also serve as the slide mechanism 20 and the locking mechanism 30.

  Further, the posts 17 positioned at the corners of the release mesh 501 on the side facing the inspection window 53, that is, the pair of posts 17 disposed at positions sandwiching the handhole 113, ride the corners of the fixed flooring 13. 5 has a notch 173 that passes toward the inside. The fixed flooring 13, the movable flooring 14, and the adjacent edges of the movable flooring 14 have continuous upper surfaces and cover the tops 172 of the posts 17.

  The floor lighting device 10 configured as described above has the same outer shape of the movable floor material 14, and includes posts 17 at intersections of the floor reinforcing material 11 at the four corners of the mesh 50. Therefore, the movable flooring 14 can be moved in any direction in the width direction crossing the entrance 51 and in the depth direction orthogonal thereto, as long as the adjacent mesh 10 is vacant.

  Accordingly, if the cell 50 opened at one place is obtained by removing the fixed floor material 13, the operation of moving the movable floor material 14 covering the adjacent cell 40 to the cell 40 opened thereafter is continued.
