[Figure 9] Figure 8 is a cross-sectional view along the line IX-IX, showing the state where the first absorbent mat in Figure 3 is in the first installation position and the second absorbent mat is in the second installation position.

[0009] Embodiments of this disclosure will be described below with reference to the drawings. Embodiment 1. Figure 1 is a side view showing an elevator 100 to which the water-absorbing mat device according to Embodiment 1 is applied. Figure 2 is a cross-sectional view along the line II-II in Figure 1. Figure 3 is a cross-sectional view along the line III-III in Figure 2.

[0010] The elevator 100 includes a passenger car 101, a water-absorbing mat device 1, a counterweight 103, a hoisting machine 104, a deflector wheel 105, a main rope 106, an elevator control device (not shown), and a plurality of operation panels 115.

[0011] The cage 101 and the counterweight 103 are connected to each other by a main rope 106. One end of the main rope 106 is connected to the top of the cage 101. The other end of the main rope 106 is connected to the top of the counterweight 103.

[0012] The hoisting machine 104 has a drive sheave (not shown), and the main rope 106 is wound around the drive sheave and the deflector 105. The elevator car 101 and counterweight 103 are suspended from the main rope 106 within the elevator shaft 120.

[0013] The elevator car 101 and counterweight 103 can move vertically inside the elevator shaft 120 in accordance with the operation of the hoisting machine 104. In Figure 1, the elevator car 101 is stopped at a position corresponding to the landing on the lowest floor, the 1st floor.

[0014] The elevator control unit controls the operation of the elevator car 101 by controlling the hoisting machine 104 based on signals from each control panel 115. Each control panel 115 is installed at the landing of each floor.

[0015] Passengers of elevator 100 can operate the control panel 115 to move the elevator car 101 to the landing floor where they are waiting.

[0016] The car 101 has a car body 102 and a car door (not shown). The car body 102 has a wall 102a, a car ceiling member 102e, and a car floor member 102f.

[0017] The wall 102a has a first side wall 110a, a second side wall 110b, a front wall 110c, and a rear wall 110d. The first side wall 110a and the second side wall 110b are arranged opposite to each other. The front wall 110c is arranged by being connected to each of the landing-side ends of the first side wall 110a and the second side wall 110b.

[0018] The rear wall 110d is arranged by being connected to each of the ends of the first side wall 110a and the second side wall 110b on the side opposite to the landing. The front wall 110c and the rear wall 110d are arranged opposite to each other.

[0019] The car ceiling member 102e closes the upper part of the space surrounded by the first side wall 110a, the second side wall 110b, the front wall 110c, and the rear wall 110d. The car floor member 102f closes the lower part of the space surrounded by the first side wall 110a, the second side wall 110b, the front wall 110c, and the rear wall 1i0d. The surface of the car floor member 102f on the inner side of the car 101 is the floor surface 102FL.

[0020] A first opening 110ah, which is an opening, is formed at the lower end of the first side wall 110a. A second opening 110bh, which is an opening, is formed at the lower end of the second side wall 110b.

[0021] An entrance / exit 110g, which is an opening, is provided in the front wall 110c. The car door can close the entrance / exit 110g.

[0022] When the car 101 stops at a stop position corresponding to the target landing, the elevator control device moves the car door to open the entrance / exit 110g. In a state where the entrance / exit 110g is open, passengers can move between the inside of the car 101 and the landing through the entrance / exit 110g.

[0023] The water-absorbing mat device 1 comprises a water-absorbing mat mechanism 2 and an operating unit 5 for driving the water-absorbing mat mechanism 2. The water-absorbing mat mechanism 2 has a first mat unit 3A and a second mat unit 3B.

[0024] The first mat unit 3A is located on the outside of the cage 101 and on the side of the first side wall 110a. The first mat unit 3A comprises a first housing 10A, a first moving mechanism 20A, a first water-absorbing mat 30A, and a first control unit 50A.

[0025] Figure 4 is a perspective view showing the first housing 10A of Figure 2. Figure 4 shows the first housing 10A as seen from the first side wall 110a side. The shape of the first housing 10A is a rectangular parallelepiped.

[0026] The first housing 10A includes a pair of first housing vertical plate members 11A, a pair of first housing horizontal plate members 12A, a first housing side wall 13A, and a first guide plate 15A.

[0027] The explanation continues based on Figures 2 to 4. The pair of first housing vertical members 11A and the pair of first housing horizontal members 12A are arranged to protrude in the direction normal to the outer surface of the first side wall 110a.

[0028] The pair of first housing vertical plate members 11A are arranged with their longitudinal direction aligned with the vertical direction. The pair of first housing horizontal plate members 12A are arranged with their longitudinal direction aligned with the horizontal direction.

[0029] When the outer surface of the first side wall 110a is viewed from the direction normal to the outer surface of the first side wall 110a, a rectangular space is formed on the outer surface of the first side wall 110a, enclosed by a pair of first housing vertical plate members 11A and a pair of first housing horizontal plate members 12A.

[0030] The first housing side wall 13A is positioned opposite the first side wall 110a. The first housing side wall 13A is positioned along the respective ends of the pair of first housing vertical plate members 11A and the pair of first housing horizontal plate members 12A. The first housing side wall 13A closes off the rectangular space enclosed by the pair of first housing vertical plate members 11A and the pair of first housing horizontal plate members 12A.

[0031] Each of the upper ends of the pair of first housing vertical plate members 11A is provided with a first housing through-hole 14A.

[0032] The first guide board 15A is a long board. The first guide board 15A is positioned at the lower end of the interior of the space enclosed by the first side wall 110a and the first housing 10A. The first guide board 15A is positioned so that its longitudinal direction is aligned with the horizontal direction.

[0033] One side of the first guide plate 15A, along its longitudinal direction, is positioned on the side wall 13A of the first housing, and the other side, along its longitudinal direction, is positioned on the side wall 110a of the first housing. The first guide plate 15A is positioned so as to slope downward from the side wall 13A of the first housing towards the side wall 110a.

[0034] The first guide plate 15A is curved when viewed along its longitudinal direction. The first guide plate 15A is positioned such that its curvature protrudes from the inside to the outside of the car 101. In this embodiment, the first guide plate 15A is curved when viewed along its longitudinal direction, but the first guide plate 15A may also be formed into a curved shape by bending it in one or more places.

[0035] Returning to Figure 3 from Figure 1, we continue the explanation. The first moving mechanism 20A includes a first motor 21A, a first shaft 22A connected to the rotation axis of the first motor 21A, and a first torque sensor 23A as a first detector. The first moving mechanism 20A moves the first water-absorbing mat 30A.

[0036] The first motor 21A is supported on the outside of the first housing 10A. The first motor 21A is powered by electricity supplied from a power supply means (not shown). The first motor 21A is controlled by the first control unit 50A. The first control unit 50A will be described later.

[0037] The first shaft 22A is supported in the first housing 10A by passing through a pair of first housing through holes 14A. Each end of the first shaft 22A is rotatably supported in the pair of first housing through holes 14A. The first shaft 22A may also be supported in each of the first housing through holes 14A via bearing members.

[0038] The rotational motion of the first motor 21A is transmitted from the rotation axis of the first motor 21A to the first shaft 22A. Due to the rotational motion of the first motor 21A, the first shaft 22A rotates around its axis.

[0039] The first torque sensor 23A detects the rotational torque applied to the first shaft 22A. The rotational torque detected by the first torque sensor 23A is transmitted to the first control unit 50A via wiring (not shown). The first control unit 50A controls the first motor 21A based on the detection result of the first torque sensor 23A. The control method of the first control unit 50A will be explained later.

[0040] Furthermore, a transmission mechanism such as a speed changer, which is composed of components such as gears, may be connected between the rotating shaft of the first motor 21A and the first shaft 22A.

[0041] The first absorbent mat 30A is a sheet-like material. Figure 5 is a top view showing the first absorbent mat 30A in Figure 2. Figure 6 is a bottom view showing the first absorbent mat 30A in Figure 2.

[0042] The first absorbent mat 30A includes a first absorbent mat body 31A, a first contact member 32A installed on the back surface of the first absorbent mat body 31A, a first connecting portion 33A, and a plurality of first wires 34A which are first winding members.

[0043] The first absorbent mat body 31A includes a plurality of first absorbent plates 40A arranged in the direction of movement of the first absorbent mat 30A, and a first connecting member (not shown) that connects each of the plurality of first absorbent plates 40A to one another. Each first absorbent plate 40A is a long plate material. In this embodiment, eight first absorbent plates 40A are used.

[0044] Each first water-absorbing plate 40A is connected to one another by a first connecting member in a direction perpendicular to its respective longitudinal direction. The first connecting member bends between adjacent connected first water-absorbing plates 40A, making the first water-absorbing mat body 31A bendable in the direction in which the first water-absorbing plates 40A are aligned.

[0045] The first water-absorbing plate 40A is a plate material containing diatomaceous earth components. For example, the first water-absorbing plate 40A is formed by firing diatomaceous earth. Diatomaceous earth is a deposit consisting of the remains of diatoms. Diatomaceous earth is a porous material whose main component is silicon dioxide hydrate.

[0046] Diatomaceous earth components have excellent water absorption and moisture absorption properties. The first water-absorbing board 40A has superior water absorption and moisture absorption properties compared to board materials that do not contain diatomaceous earth components, water-absorbing materials, or moisture-absorbing materials.

[0047] The coefficient of friction between the first contact member 32A and the floor surface 102FL of the cage 101 is smaller than the coefficient of friction between the first water-absorbing mat body 31A and the floor surface 102FL of the cage 101. In this embodiment, the first contact member 32A is five steel tapes.

[0048] The first connecting portion 33A is located at one end of the first absorbent mat body 31A. The first connecting portion 33A includes a first connecting portion body 45A and a plurality of first magnets 46A which are first connecting members.

[0049] The first connecting body 45A is a plate material having the same length as the first water-absorbing plate 40A. Multiple first magnets 46A are arranged on the side of the first connecting body 45A opposite to the side facing the first water-absorbing plate 40A.

[0050] One end of each first wire 34A is connected to the end of the first absorbent mat body 31A opposite to the end where the first connecting part 33A is located. In this embodiment, seven first wires 34A are used.

[0051] The end where the first connection part 33A is installed is the tip of the first water-absorbing mat 30A.

[0052] Returning from Figure 1 to Figure 3, we continue the explanation. The ends of each first wire 34A opposite to the end connected to the first absorbent mat body 31A are connected to the first shaft 22A.

[0053] The first control unit 50A is supported by the first motor 21A. The first control unit 50A controls the first motor 21A based on signals from the operation unit 5. Although the first control unit 50A is supported by the first motor 21A, it is not limited to this location and may be installed anywhere.

[0054] The second mat unit 3B is located on the outside of the cage 101, on the side of the second side wall 110b. The second mat unit 3B differs from the configuration of the first mat unit 3A only in that it is located on the second side wall 110b. Therefore, the description of the second mat unit 3B is the same as the description of the first mat unit 3A above, but with the prefix "first" replaced with "second," the last letter "A" replaced with "B," and "first side wall 110a" replaced with "second side wall 110b."

[0055] Figure 7 is a front view showing the operation panel 115 of Figure 1. The operation unit 5 is attached to at least one of the operation panels 115. The operation unit 5 has operation buttons 60 and wiring (not shown) which are transmission members that transmit signals from the operation buttons 60.

[0056] The operation button 60 is located on at least one of the multiple operation panels 115. The contact signals from the operation button 60 are input to the first control unit 50A and the second control unit 50B via wiring.

[0057] The water-absorbing mat device 1 is operated by the building manager. Therefore, the operation button 60 is located on the control panel 115 installed on the landing floor on the floor where the building manager's office is located. In this embodiment, the control panel 115 on which the operation button 60 is located is installed on the landing floor of the lowest floor.

[0058] Next, the state of the first absorbent mat 30A and the second absorbent mat 30B will be described. Figures 2 and 3 show the state in which the first absorbent mat 30A is in the first retracted position and the second absorbent mat 30B is in the second retracted position. That is, the first absorbent mat 30A is pulled into the interior of the first housing 10A and the second absorbent mat 30B is pulled into the interior of the second housing 10B.

[0059] The rotation of the first motor 21A and the first shaft 22A causes each first wire 34A to be wound onto the first shaft 22A. With each first wire 34A wound up, the first absorbent mat 30A is housed in the internal space of the first housing 10A. That is, the first absorbent mat 30A is located on the back side of the first side wall 110a of the cage 101. In this state, the first absorbent mat 30A is in the first retracted position.

[0060] The rotation of the second motor 21B and the second shaft 22B causes each second wire 34B to be wound onto the second shaft 22B. With each second wire 34B wound up, the second water-absorbing mat 30B is stored in the internal space of the second housing 10B. That is, the second water-absorbing mat 30B is located on the back side of the second side wall 110b of the cage 101. In this state, the second water-absorbing mat 30B is in the second retracted position.

[0061] When the first water-absorbing mat 30A is in the first retraction position and the second water-absorbing mat 30B is in the second retraction position, the floor surface 102FL of the cage 101 is exposed.

[0062] Figure 8 is a cross-sectional view showing the state in Figure 2 where the first absorbent mat 30A is in the first installation position and the second absorbent mat 30B is in the second installation position. Figure 9 is a cross-sectional view along the line IX-IX in Figure 8 showing the state in Figure 3 where the first absorbent mat 30A is in the first installation position and the second absorbent mat 30B is in the second installation position.

[0063] Due to the rotation of the first motor 21A and the first shaft 22A, each first wire 34A is unwound from the first shaft 22A. The first absorbent mat body 31A extends from the first housing 10A.

[0064] The first absorbent mat body 31A is fed out from the first housing 10A through the first opening 110ah and covers the floor surface 102FL. That is, the first absorbent mat body 31A is in a position to be laid on the floor surface 102FL of the cage 101. In this state, the first absorbent mat 30A is in the first laying position.

[0065] Similarly, the rotation of the second motor 21B and the second shaft 22B causes each second wire 34B to unwind from the second shaft 22B. The second absorbent mat body 31B extends from the second housing 10B.

[0066] The second absorbent mat body 31B is fed out from the second housing 10B through the second opening 110bh and covers the floor surface 102FL. That is, the second absorbent mat body 31B is in a position to be laid on the floor surface 102FL of the cage 101. In this state, the second absorbent mat 30B is in the second laying position.

[0067] When the first absorbent mat 30A is in the first installation position and the second absorbent mat 30B is in the second installation position, the first absorbent mat 30A and the second absorbent mat 30B are aligned with each other on the floor surface 102FL of the cage 101. The leading edge of the first absorbent mat 30A and the leading edge of the second absorbent mat 30B are in contact with each other.

[0068] The first absorbent mat 30A and the second absorbent mat 30B, which are in contact with each other, are connected by the magnetic force of the first magnet 46A and the second magnet 46B. In other words, the first connecting part 33A and the second connecting part 33B are detachably connected to each other.

[0069] Next, the operation of the water-absorbing mat device 1 will be explained. In order to activate the water-absorbing mat device 1, it is necessary for a worker to press the operation button 60 on the control unit 5. A worker, such as the elevator manager 100, will decide whether or not to activate the water-absorbing mat device 1 based on environmental conditions such as the amount of rainfall.

[0070] If the worker determines that it is necessary to activate the water-absorbing mat device 1, the worker operates the operation button 60. That is, the worker presses the operation button 60.

[0071] Since the information from the operation button 60 is input to the first control unit 50A and the second control unit 50B via wiring, the first control unit 50A and the second control unit 50B are aware that the operation button 60 is pressed.

[0072] The first control unit 50A knows whether the first water-absorbing mat 30A is in the first retracted position or the first laid position. When it detects that the operation button 60 is pressed, the first control unit 50A determines the position of the first water-absorbing mat 30A.

[0073] When the first control unit 50A determines that the first water-absorbing mat 30A is in the first retracted position, it rotates the first motor 21A in the sending direction.

[0074] The feeding direction of the rotation of the first motor 21A is the direction in which the first water-absorbing mat 30A moves from the first retracted position to the first laying position, that is, the rotation direction in which the first water-absorbing mat 30A is fed out from the first housing 10A. The feeding direction of the rotation of the first shaft 22A is the same direction.

[0075] The rotational force of the first motor 21A is transmitted to the first shaft 22A. The first shaft 22A rotates in the feeding direction around its axis. As a result, each of the first wires 34A that were wound around the first shaft 22A is unwound.

[0076] When the first wire 34A is released from the first shaft 22A, the first absorbent mat 30A moves in a direction that pushes it out of the first housing 10A. At this time, the first absorbent mat 30A is subjected to gravity acting on the mat itself, and the force acting on the first absorbent mat 30A as each of the first wires 34A is released pushes it out of the first housing 10A. Due to these forces, the first absorbent mat 30A moves in a direction that pushes it out of the first housing 10A.

[0077] When the first absorbent mat 30A moves, the first contact member 32A, which is installed on the back surface of the first absorbent mat 30A, comes into contact with the first guide plate 15A. As a result, the first absorbent mat 30A moves smoothly along the first guide plate 15A.

[0078] Furthermore, as the first motor 21A rotates, the first water-absorbing mat 30A passes through the first opening 110ah and moves over the floor surface 102FL of the cage 101. When the first water-absorbing mat 30A moves, the first contact member 32A is in contact with the floor surface 102FL of the cage 101.

[0079] Furthermore, as the first water-absorbing mat 30A continues to be fed out from the first housing 10A, the first water-absorbing mat 30A eventually reaches the first installation position. When the first water-absorbing mat 30A is in the first installation position, it is positioned to cover the floor surface 102FL of the cage 101.

[0080] Similar to the first absorbent mat 30A described above, when the operation button 60 is pressed, the second absorbent mat 30B, which is in the second retracted position, is also sent out from the second housing 10B. Eventually, the second absorbent mat 30B passes through the second opening 110bh and reaches the second laying position.

[0081] When the first water-absorbing mat 30A reaches the first laying position and the second water-absorbing mat 30B reaches the second laying position, the first connection part 33A and the second connection part 33B come into contact with each other. When the first connection part 33A and the second connection part 33B come into contact with each other, the detected torque of the first torque sensor 23A and the detected torque of the second torque sensor 23B each fluctuate.

[0082] The first control unit 50A recognizes that the first water-absorbing mat 30A has reached the first laying position based on the behavior of the torque detected from the first torque sensor 23A. As a result, the first control unit 50A stops the rotation of the first motor 21A.

[0083] The first control unit 50A stores in a memory area (not shown) within the first control unit 50A that the first water-absorbing mat 30A has reached the first laying position. This completes the movement of the first water-absorbing mat 30A to the laying position.

[0084] Similarly, the second control unit 50B recognizes that the second water-absorbing mat 30B has reached the second laying position based on the behavior of the torque detected from the second torque sensor 23B. As a result, the second control unit 50B stops the rotation of the second motor 21B.

[0085] The second control unit 50B stores in a memory area (not shown) within the second control unit 50B that the second water-absorbing mat 30B has reached the second laying position.

[0086] When the first absorbent mat 30A reaches the first installation position and the second absorbent mat 30B reaches the second installation position, that is, when the first connecting part 33A and the second connecting part 33B are in contact with each other, the first magnet 46A and the second magnet 46B are attracted to and connected to each other. This completes the movement of the second absorbent mat 30B to the second installation position.

[0087] Once the first absorbent mat 30A has moved to its first installation position and the second absorbent mat 30B has moved to its second installation position, the absorbent mat device 1 is stopped.

[0088] Next, we will explain the case where the first absorbent mat 30A is moved to the first retracted position and the second absorbent mat 30B is moved to the second retracted position. First, we will explain the operation of the first absorbent mat 30A.

[0089] The worker presses the operation button 60. The first control unit 50A and the second control unit 50B recognize that the operation button 60 is pressed.

[0090] When the first control unit 50A detects that the operation button 60 is pressed while the first water-absorbing mat 30A is in the first laying position, it rotates the first motor 21A in the winding direction. The winding direction is the direction of rotation opposite to the feed direction.

[0091] In other words, the winding direction, which is the rotation direction of the first motor 21A, is the direction in which the first water-absorbing mat 30A moves from the first laying position to the first retracted position, or in other words, the rotation direction that moves the first water-absorbing mat 30A toward the interior of the first housing 10A. The winding direction of the rotation direction of the first shaft 22A is the same direction.

[0092] The rotational force of the first motor 21A is transmitted to the first shaft 22A. The first shaft 22A rotates in the winding direction around its axis. As a result, each first wire 34A is wound onto the first shaft 22A.

[0093] When each first wire 34A is wound onto the first shaft 22A, the first water-absorbing mat 30A moves on the floor surface 102FL of the basket 101 and moves toward the first housing 10A through the first opening 110ah.

[0094] When the first absorbent mat 30A moves, the first contact member 32A installed on the back surface of the first absorbent mat 30A comes into contact with the floor surface 102FL of the cage 101 and the first guide plate 15A. As a result, the first absorbent mat 30A moves smoothly along the floor surface 102FL of the cage 101 and the first guide plate 15A.

[0095] Furthermore, as the first motor 21A continues to rotate, all of the first wires 34A are wound onto the first shaft 22A. As a result, the first water-absorbing mat 30A reaches the first retracted position. When the first motor 21A is in the first retracted position, the first water-absorbing mat body 31A does not cover the floor surface 102FL of the cage 101, but is located inside the first housing 10A.

[0096] When all of each first wire 34A is wound onto the first shaft 22A, the detected torque of the first torque sensor 23A changes. Similarly, when all of each second wire 34B is wound onto the second shaft 22B, the detected torque of the second torque sensor 23B changes.

[0097] The first control unit 50A recognizes that the first water-absorbing mat 30A has reached the first retracted position based on the behavior of the torque detected from the first torque sensor 23A. As a result, the first control unit 50A stops the rotation of the first motor 21A.

[0098] The first control unit 50A stores in a storage area (not shown) within the first control unit 50A that the first water-absorbing mat 30A has reached the first retracted position. This completes the movement of the first water-absorbing mat 30A to the first retracted position.

[0099] Similar to the first absorbent mat 30A described above, when the operation button 60 is pressed, the second absorbent mat 30B also moves through the second opening 110bh to the second housing 10B. Eventually, the second absorbent mat 30B reaches the second installation position.

[0100] The second control unit 50B recognizes that the second water-absorbing mat 30B has reached the second retracted position based on the behavior of the torque detected from the second torque sensor 23B. As a result, the second control unit 50B stops the rotation of the second motor 21B.

[0101] The second control unit 50B stores in a memory area (not shown) within the second control unit 50B that the second water-absorbing mat 30B has reached the second retracted position. This completes the movement of the second water-absorbing mat 30B to the second retracted position.

[0102] Once the first absorbent mat 30A has moved to its first retracted position and the second absorbent mat 30B has moved to its second retracted position, the absorbent mat device 1 is stopped.

[0103] The water-absorbing mat device 1 according to Embodiment 1 includes a water-absorbing mat mechanism 2 installed on the cage 101 and an operating unit 5 for driving the water-absorbing mat mechanism 2. The water-absorbing mat mechanism 2 also has a first mat unit 3A, which has a first water-absorbing mat 30A and a first moving mechanism 20A for moving the first water-absorbing mat 30A. The first water-absorbing mat 30A is movable between a first retracted position located on the back side of the first side wall 110a of the cage 101 and a first laid position laid on the floor surface 102FL of the cage 101. The first moving mechanism 20A moves the first water-absorbing mat 30A between the first retracted position and the first laid position when the operating unit 5 is operated. The first water-absorbing mat 30A also has a first water-absorbing mat body 31A containing a porous material. As a result, the operator can lay the first water-absorbing mat 30A on the floor surface 102FL by operating the control unit 5 according to the rainfall conditions. Therefore, rainwater and moisture inside the elevator car 101 can be absorbed by the first water-absorbing mat 30A. Thus, the humidity inside the elevator car 101 can be kept at an appropriate level, improving the comfort level inside the elevator car 101. Furthermore, because the first water-absorbing mat 30A has excellent water absorption and quick-drying properties, it can quickly absorb moisture from the floor surface 102FL. Thus, the comfort level inside the elevator car 101 can be improved. In addition, this can reduce contamination of the floor surface 102FL with rainwater containing mud during rainfall. Furthermore, scratches and damage to the floor surface 102FL caused by umbrellas brought into the elevator car 100 can be reduced. Furthermore, rainwater and moisture inside the elevator car 101 can be absorbed by the first water-absorbing mat body 31A which contains porous material. Thus, the ability to remove moisture and humidity inside the elevator car 101 can be improved. Furthermore, when the rainfall ends, the operator can move the first water-absorbing mat 30A to the back of the first side wall 110a of the cage 101 by operating the control unit 5. Thus, the first water-absorbing mat 30A, which contains porous material, can be dried on the outside of the cage 101. As a result, the dried first water-absorbing mat 30A can be reused, improving the ability to remove moisture and humidity from inside the cage 101.Furthermore, this allows workers to lay the first water-absorbing mat 30A on the floor surface 102FL using mechanical power during rainfall. Therefore, the workload on workers can be reduced. In addition, the first water-absorbing mat 30A can be laid on the floor surface 102FL more quickly.

[0104] According to the water-absorbing mat device 1 of Embodiment 1, the first water-absorbing mat body 31A has a plurality of first water-absorbing plates 40A that are connected to each other and arranged in the direction of movement of the first water-absorbing mat 30A. Furthermore, the first water-absorbing mat body 31A is bendable in the direction in which the plurality of first water-absorbing plates 40A are arranged by bending between adjacent first water-absorbing plates 40A. This allows the use of plate material containing porous material at a higher density. Therefore, the ability to remove moisture and humidity from inside the basket 101 can be improved.

[0105] According to the water-absorbing mat device 1 of Embodiment 1, the porous material contained in the first water-absorbing mat body 31A is diatomaceous earth. This allows the use of diatomaceous earth with excellent water absorption and moisture absorption properties in the first water-absorbing mat body 31A. Therefore, the ability to remove moisture and humidity from inside the basket 101 can be improved.

[0106] According to the water-absorbing mat device 1 of Embodiment 1, the first water-absorbing mat 30A has a first contact member 32A installed on the first water-absorbing mat body 31A. When the first water-absorbing mat 30A is in the first laying position, the first contact member is in contact with the floor surface 102FL. Furthermore, the coefficient of friction between the floor surface 102FL and the first contact member 32A is smaller than the coefficient of friction between the floor surface 102FL and the first water-absorbing mat body 31A. As a result, the first water-absorbing mat 30A can move more smoothly on the floor surface 102FL. Therefore, a small motor can be used with the first motor 21A. In addition, damage to the floor surface 102FL due to the movement of the first water-absorbing mat 30A can be reduced.

[0107] According to the water-absorbing mat device 1 of Embodiment 1, the first opening 110ah is located at the lower end of the first side wall 110a. As a result, the inner surface of the first side wall 110a of the car 101 is a large, continuous surface without being partitioned by the first opening 110ah. Therefore, the aesthetic design of the car 101 is improved. In addition, passengers of the elevator 100 are less likely to notice the first opening 110ah, further improving the aesthetic design of the car 101.

[0108] According to the water-absorbing mat device 1 of Embodiment 1, the first opening 110ah is located at a position higher than the floor surface 102FL. Also, the height distance from the floor surface 102FL to the lower end of the first opening 110ah is 15 cm or more. As a result, the first water-absorbing mat 30A covers the lower end of the inner surface of the first side wall 110a up to a height of 15 cm or more from the floor surface 102FL. Therefore, contamination of the lower end of the inner surface of the first side wall 110a by rainwater containing mud during rainfall can be reduced. In addition, scratches and damage to the lower end of the inner surface of the first side wall 110a caused by umbrellas brought in by passengers of the elevator 100 can be reduced.

[0109] According to the water-absorbing mat device 1 of Embodiment 1, the first water-absorbing mat 30A has a first connecting portion 33A installed at the end of the first water-absorbing mat body 31A. Furthermore, when the first water-absorbing mat 30A is in the first laying position, the first connecting portion 33A is detachably connected to a part of the basket 101. Therefore, displacement of the first water-absorbing mat 30A can be reduced.

[0110] According to the water-absorbing mat device 1 of Embodiment 1, the first connecting portion 33A includes a magnet. Therefore, the first connecting portion 33A can be manufactured using readily available materials.

[0111] According to the water-absorbing mat device 1 of Embodiment 1, the water-absorbing mat device 1 has a second mat unit 3B, which has a second water-absorbing mat 30B and a second moving mechanism 20B for moving the second water-absorbing mat 30B. The second water-absorbing mat 30B is movable between a second retracted position located on the back side of the second side wall 110b and a second laid position laid on the floor surface 102FL. The second moving mechanism 20B moves the second water-absorbing mat 30B between the second retracted position and the second laid position when the operating unit 5 is operated. When the first water-absorbing mat 30A is in the first laid position and the second water-absorbing mat 30B is in the second laid position, the first water-absorbing mat 30A and the second water-absorbing mat 30B are side by side on the floor surface 102FL. Furthermore, the second absorbent mat 30B has a second absorbent mat body 31B containing a porous material. This allows the worker to lay the first absorbent mat 30A and the second absorbent mat 30B on the floor surface 102FL by operating the operating unit 5 according to the rainfall conditions. Thus, rainwater and moisture inside the elevator car 101 can be absorbed by the first absorbent mat 30A and the second absorbent mat 30B. As a result, the humidity inside the elevator car 101 can be kept at an appropriate level, improving the comfort level inside the elevator car 101. In addition, because the first absorbent mat 30A and the second absorbent mat 30B have excellent water absorption and quick-drying properties, they can quickly absorb moisture from the floor surface 102FL. As a result, the comfort level inside the elevator car 101 can be improved. Furthermore, this can reduce contamination of the floor surface 102FL with rainwater containing mud during rainfall. In addition, scratches and damage to the floor surface 102FL caused by umbrellas brought into the elevator car 100 can be reduced. Furthermore, rainwater and moisture inside the cage 101 can be absorbed by the first absorbent mat body 31A and the second absorbent mat body 31B, which contain porous material. Therefore, the ability to remove moisture and humidity from inside the cage 101 can be improved. In addition, when the rainfall ends, the operator can operate the control unit 5 to move the first absorbent mat 30A to the back of the first side wall 110a of the cage 101 and the second absorbent mat 30B to the back of the second side wall of the cage 101.Therefore, the first water-absorbing mat 30A and the second water-absorbing mat 30B, which contain porous material, can be dried outside the cage 101. Thus, the dried first water-absorbing mat 30A can be reused, improving the ability to remove moisture and humidity from inside the cage 101. Furthermore, this allows workers to lay the first water-absorbing mat 30A and the second water-absorbing mat 30B on the floor surface 102FL using mechanical power during rainfall. Thus, the workload on workers can be reduced. In addition, the first water-absorbing mat 30A and the second water-absorbing mat 30B can be laid on the floor surface 102FL more quickly. Moreover, since the water-absorbing mat covering the floor surface 102FL is divided into the first water-absorbing mat body 31A and the second water-absorbing mat body 31B, the first mat unit 3A and the second mat unit 3B, which include components such as the housing, motor, and shaft, can be miniaturized.

[0112] According to the water-absorbing mat device 1 of Embodiment 1, the second water-absorbing mat body 31B has a plurality of second water-absorbing plates 40B that are connected to each other and arranged in the direction of movement of the second water-absorbing mat 30B. Furthermore, the second water-absorbing mat body 31B is bendable in the direction in which the plurality of second water-absorbing plates 40B are arranged by bending between adjacent second water-absorbing plates 40B. This allows the use of plate material containing porous material at a higher density. Therefore, the ability to remove moisture and humidity from inside the basket 101 can be improved.

[0113] According to the water-absorbing mat device 1 of Embodiment 1, the porous material contained in the second water-absorbing mat body 31B is diatomaceous earth. This allows the use of diatomaceous earth with excellent water absorption and moisture absorption properties in the second water-absorbing mat body 31B. Therefore, the ability to remove moisture and humidity from inside the basket 101 can be improved.

[0114] According to the water-absorbing mat device 1 of Embodiment 1, the first water-absorbing mat 30A has a first connecting portion 33A, and the second water-absorbing mat 30B has a second connecting portion 33B. Furthermore, when the first water-absorbing mat 30A is located in the first laying position and the second water-absorbing mat 30B is located in the second laying position, the first connecting portion 33A and the second connecting portion 33B are detachably connected to each other. Therefore, misalignment of the first water-absorbing mat 30A and the second water-absorbing mat 30B can be reduced.

[0115] According to the water-absorbing mat device 1 of Embodiment 1, the first connecting portion 33A and the second connecting portion 33B each contain a magnet. Therefore, the first connecting portion 33A and the second connecting portion 33B can be manufactured using readily available materials.

[0116] According to the water-absorbing mat device 1 of Embodiment 1, the second opening 110bh is located at the lower end of the second side wall 110b. As a result, the inner surface of the second side wall 110b of the car 101 is a large, continuous surface without being partitioned by the second opening 110bh. Therefore, the aesthetic design of the car 101 is improved. In addition, passengers of the elevator 100 are less likely to notice the second opening 110bh, further improving the aesthetic design of the car 101.

[0117] According to the water-absorbing mat device 1 of Embodiment 1, the second opening 110bh is located higher than the floor surface 102FL, and the height distance from the floor surface 102FL to the lower end of the second opening 110bh is 15 cm or more. As a result, the second water-absorbing mat body 31B covers the lower end of the inner surface of the second side wall 110b up to a height of 15 cm or more from the floor surface 102FL. Therefore, contamination of the lower end of the inner surface of the second side wall 110b by rainwater containing mud during rainfall can be reduced. In addition, scratches and damage to the lower end of the inner surface of the second side wall 110b caused by umbrellas brought in by passengers of the elevator 100 can be reduced.

[0118] According to the water-absorbing mat device 1 of Embodiment 1, the operating unit 5 has one operating button 60, and the water-absorbing mat device 1 is driven when the operating button 60 is operated. As a result, the operator can easily drive the water-absorbing mat device 1 by operating one operating button 60.

[0119] According to the water-absorbing mat device 1 of Embodiment 1, the operating unit 5 is attached to an operating panel installed in the elevator landing. This allows the operator to easily operate the operating buttons 60.

[0120] The first water-absorbing plate 40A and the second water-absorbing plate 40B in Embodiment 1 contain diatomaceous earth components. However, they are not limited to this. The first water-absorbing plate 40A and the second water-absorbing plate 40B may also contain materials with excellent water absorption properties. For example, porous materials may be used as materials with excellent water absorption properties.

[0121] Furthermore, the first absorbent mat body 31A of Embodiment 1 has eight first absorbent plates 40A, and the second absorbent mat body 31B has eight second absorbent plates 40B. However, it is not limited to this. Flexible sheet materials may be used as the first absorbent mat body 31A and the second absorbent mat body 31B. In this case, in order to give the sheet material water absorption and moisture absorption properties, a porous material, preferably a material containing diatomaceous earth components, may be attached to or incorporated into the base material of the sheet material. Also, in this case, it is not necessary to use the first connecting member and the second connecting member.

[0122] Furthermore, the first connecting member and the second connecting member of Embodiment 1 are well-known members capable of connecting multiple plate materials. For example, adhesive tape, hook-and-loop fasteners, and hinges may be used as the first connecting member. Alternatively, a bag-shaped member may be used as the first connecting member. The bag-shaped member has compartments equal to the number of first water-absorbing plates 40A, and one compartment can hold a first water-absorbing plate 40A. By placing a first water-absorbing plate 40A in each compartment, they are connected so that they are aligned perpendicular to the longitudinal direction of each first water-absorbing plate 40A. Furthermore, the first contact member 32A may also be used as the first connecting member. Each first water-absorbing plate 40A may be connected to each other by attaching each first contact member 32A across each first water-absorbing plate 40A. Furthermore, each first water-absorbing plate 40A may be connected by arranging one of the multiple first wires 34A across each first water-absorbing plate 40A. The second connecting member can have the same configuration as the first connecting member.

[0123] Furthermore, the first contact member 32A in Embodiment 1 is five steel tapes. However, it is not limited to this. For example, four or fewer, or six or more steel tapes may be used. For example, the first contact member 32A may be a member in which a resin such as fluororesin is exposed to the floor surface 102FL of the cage 101. Moreover, for example, multiple rollers may be used as the first contact member 32A. This allows the first water-absorbing mat 30A to move more smoothly on the floor surface 102FL. Consequently, a small motor can be used with the first motor 21A. In addition, damage to the floor surface 102FL due to the movement of the first water-absorbing mat 30A can be reduced.

[0124] Furthermore, the water-absorbing mat device 1 of Embodiment 1 has a first mat unit 3A and a second mat unit 3B. However, it is not limited to this. The water-absorbing mat device 1 may have only one of the first mat unit 3A and the second mat unit 3B. For example, the water-absorbing mat device 1 may have only the first mat unit 3A. In this case, when the first water-absorbing mat 30A is in the first laying position, the first connecting portion 33A may be in contact with the second side wall 110b. That is, the first connecting portion 33A may be detachably connected to the inside of the second side wall 110b by magnetic force. Moreover, the water-absorbing mat device 1 may have only the first mat unit 3A which is located outside the back wall 110d. In this case, the first opening 110ah is formed in the back wall 110d.

[0125] Furthermore, in Embodiment 1, a plurality of first magnets 46A are arranged in the first connection portion 33A, and a plurality of second magnets 46B are arranged in the second connection portion 33B. However, it is not limited to this. For example, mechanical connecting members such as hooks, buttons, or hook fasteners may be used in the first connection portion 33A and the second connection portion 33B.

[0126] Furthermore, the first connection part 33A and the second connection part 33B in Embodiment 1 are connected to each other. However, this is not the only connection. The first connection part 33A and the second connection part 33B may be connected to any part inside the cage 101. For example, they may be connected to the floor surface 102FL or a part of the rear wall 110d.

[0127] Furthermore, in Embodiment 1, a first torque sensor 23A is used as the first detector and a second torque sensor 23B is used as the second detector. However, the invention is not limited to these. For example, limit switches or photosensors may be used as the first and second detectors. The positions of the first water-absorbing mat 30A and the second water-absorbing mat 30B can also be detected using limit switches or photosensors. Alternatively, encoders that detect the amount of rotation of the first shaft 22A and the second shaft 22B may be arranged as the first and second detectors. The positions of the first water-absorbing mat 30A and the second water-absorbing mat 30B may be determined by calculating the distance traveled by the first water-absorbing mat 30A and the second water-absorbing mat 30B based on the output of each encoder.

[0128] Furthermore, in Embodiment 1, the first control unit 50A and the second control unit 50B independently perform control based on the state in which the operation button 60 is pressed. However, this is not the only way. For example, the first control unit 50A and the second control unit 50B may perform control after mutually recognizing each other's operating status and information in their memory. For example, when the operation button 60 is pressed, if the positions of the first absorbent mat 30A and the second absorbent mat 30B are different, the first control unit 50A and the second control unit 50B do not need to operate the first motor 21A and the second motor 21B. This allows the absorbent mat device 1 to be driven more safely.

[0129] Furthermore, the first control unit 50A and the second control unit 50B of Embodiment 1 store the position of the first water-absorbing mat 30A or the second water-absorbing mat 30B in a storage area (not shown). However, this is not the only option. For example, a limit switch or a photosensor may be used to detect the positions of the first water-absorbing mat 30A and the second water-absorbing mat 30B.

[0130] Furthermore, the operation button 60 of Embodiment 1 may display the operating status of the water-absorbing mat device 1. For example, a lighting device may be placed inside the operation button 60, and the operating status of the water-absorbing mat device 1 may be displayed by the state in which the lighting device is lit. For example, when the first water-absorbing mat 30A is in the first laying position and the second water-absorbing mat 30B is in the first laying position, the lighting inside the operation button 60 may be turned on. Also, when at least one of the first motor 21A and the second motor 21B is operating, the lighting inside the operation button 60 may be made to blink.

[0131] Furthermore, the water-absorbing mat device 1 of Embodiment 1 has an operating button 60 exposed on the surface of the operation panel 115. However, it is not limited to this. For example, the operating button 60 may be placed in a space enclosed by a lid within the wall of the landing, or in a space enclosed by a lid inside the elevator car 101. Alternatively, the operating button 60 may be placed in the building's management room, or inside the control panel of the elevator 100.

[0132] Furthermore, the absorbent mat device 1 of Embodiment 1 has an operation button 60. However, it is not limited to this. For example, a drive signal to the absorbent mat device 1 may be transmitted by pressing the buttons that are standardly equipped on the operation panel 115 in a predetermined order. This eliminates the need to specially install the operation button 60 on the operation panel 115.

[0133] Furthermore, the absorbent mat device 1 of Embodiment 1 has one operation button 60. However, it is not limited to this. For example, it may have two operation buttons, one corresponding to the first mat unit 3A and the other to the second mat unit 3B.

[0134] Furthermore, in Embodiment 1, the first opening 110ah is formed at the lower end of the first side wall 110a, and the second opening 110bh is formed at the lower end of the second side wall 110b. However, it is not limited to this. For example, the first opening 110ah and the second opening 110bh may be formed above the corresponding lower ends of the first side wall 110a and the second side wall 110b. For example, the first opening 110ah and the second opening 110bh may be located at a position higher than the floor surface 102FL of the cage 101. For example, the height distance from the floor surface 102FL of the cage 101 to the lower ends of the first opening 110ah and the second opening 110bh may be 15 cm or more.

[0135] Furthermore, the elevator 100 of Embodiment 1 operates with the first water-absorbing mat 30A in the first installation position and the second water-absorbing mat 30B in the second installation position. In this case, the stopping position of the car 101 corresponding to each floor may be changed. For example, when the first water-absorbing mat 30A is in the first installation position and the second water-absorbing mat 30B is in the second installation position, the stopping position of the car 101 may be set lower than the standard stopping position of the car 101 by the thickness of the first water-absorbing mat 30A. Here, the standard stopping position of the car 101 is the stopping position of the car 101 when the first water-absorbing mat 30A is in the first retracted position and the second water-absorbing mat 30B is in the second retracted position.
