Film device

Abstract

A film device according to the present disclosure comprises a support mechanism. The support mechanism supports a car film in such a manner that, as a tip-end portion of the support mechanism moves in a direction away from the support mechanism, the car film can be fed to a protection position, which is a position for covering an area to be protected set on the inner surface of a car. The feeding direction in which the car film is fed is along the longitudinal direction of the car film. When the car film placed in the protection position is cut in a direction intersecting the longitudinal direction of the car film at a position between a base-end portion and a tip-end portion of the car film, thereby creating a new tip-end portion at the end portion on the opposite side from the base-end portion in the longitudinal direction of the car film having the base-end portion, the support mechanism can feed the car film having the new tip-end portion to the protection position.

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Embodiment 1. FIG. 1 is a side view showing an elevator 100 to which a film device according to Embodiment 1 is applied. FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1. FIG. 3 is an enlarged view of part III of the first film unit 3A in FIG. 2.

[0010] The elevator 100 has a basket 101 on which passengers can ride, a counterweight 103, a hoisting machine 104, a deflector sheave 105, a main rope 106, and an elevator control device (not shown).

[0011] The basket 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 upper part of the basket 101. The other end of the main rope 106 is connected to the upper part 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 sheave 105. In the hoistway 120, the basket 101 and the counterweight 103 are suspended by the main rope 106.

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

[0014] The car 101 has a rectangular parallelepiped-shaped car body 102 into which passengers can board and a car door (not shown).

[0015] The car body 102 has a wall 102a, a car door wall 102b that supports the car door, a car ceiling member 102c, a car floor member 102d, and an internal ceiling plate 102e.

[0016] The car body 102 has walls in four directions. The wall 102a is three consecutive walls out of the four walls of the car body 102. The car door wall 102b is one wall of the car body 102 other than the wall 102a among the four walls of the car body 102.

[0017] The internal ceiling plate 102e closes the upper part of the space surrounded by the wall 102a and the car door wall 102b. The car floor member 102d closes the lower part of the space surrounded by the wall 102a and the car door wall 102b.

[0018] The internal ceiling plate 102e is arranged inside the car body 102. The internal ceiling plate 102e faces the car floor member 102d.

[0019] An entrance / exit (not shown), which is an opening, is provided in the car door wall 102b. The car door can block the entrance / exit. When the car 101 stops at a stop position corresponding to the target landing and the car door moves, the entrance / exit is opened.

[0020] When the entrance / exit is open, passengers can move between the inside of the car 101 and the landing through the entrance / exit.

[0021] The wall 102a has a first side wall 110a, a second side wall 110b, and a rear wall 110c. The first side wall 110a and the second side wall 110b are arranged opposite to each other. Each of the ends of the first side wall 110a and the second side wall 110b on the landing side is connected to and arranged on the car door wall 102b.

[0022] The surface of the first side wall 110a exposed inside the car 101 is defined as the first inner surface 111a. The surface of the second side wall 110b exposed inside the car 101 is defined as the second inner surface 111b. The surface of the rear wall 110c exposed inside the car 101 is defined as the third inner surface 111c.

[0023] The rear wall 110c is connected to and arranged at each of the ends of the first side wall 110a and the second side wall 110b on the side opposite to the landing. The car door wall 102b and the rear wall 110c are arranged opposite to each other.

[0024] That is, among the four-direction walls of the car body 102, each of the three consecutive-direction walls is, in order, the first side wall 110a, the rear wall 110c, and the second side wall 110b.

[0025] A first opening 110ah is formed on the first side wall 110a side of the internal ceiling plate 102e. A second opening 110bh is formed on the second side wall 110b side of the internal ceiling plate 102e.

[0026] FIG. 4 is a schematic view of the first side wall 110a seen from the inside of the car 101 in FIG. 1. The car 101 has an operation panel 115 arranged inside the car 101 as car interior equipment, and a handrail 116 arranged inside the car 101.

[0027] A first protected area 112a as a protected area is set on the first inner surface 111a. The first protected area 112a will be described later.

[0028] Returning to FIGS. 1 to 3, the description will be continued. The basket 101 further has a film device 1. The film device 1 includes a film mechanism 2. The film mechanism 2 has a first film unit 3A as a film unit and a second film unit 3B.

[0029] The first film unit 3A is disposed in the basket main body 102. The first film unit 3A is disposed in the space between the basket ceiling member 102c and the internal ceiling plate 102e.

[0030] FIG. 5 is a partial cross-sectional view taken along the line V-V of the first film unit 3A in FIG. 3. The first film unit 3A includes a first support mechanism 10A as a support mechanism, a first rotation control mechanism 30A that is a rotation control mechanism, and a first film roll 40A that is a film roll supported by a pair of first roll support portions 20A.

[0031] The first support mechanism 10A includes a pair of first arm members 11A, a first support plate 12A that supports each of the pair of first arm members 11A, and a pair of first roll support portions 20A that are respectively supported by the pair of first arm members 11A.

[0032] Each first arm member 11A has a first arm main body 11aA and a first bearing member 11bA. On one surface of the first arm main body 11aA, a first shaft support portion 11cA that supports the first bearing member 11bA is formed.

[0033] The first shaft support portion 11cA is a recess formed on one surface of the first arm main body 11aA. The first bearing member 11bA is fitted into the first shaft support portion 11cA. The first bearing member 11bA has an axis.

[0034] The first support plate 12A is a plate-shaped member. The first support plate 12A is supported by the basket body 102. The first support plate 12A is arranged such that the longitudinal direction of the first support plate 12A is along the horizontal direction and along the width direction of the first side wall 110a. At both ends in the longitudinal direction of the first support plate 12A, respective ones of a pair of first arm members 11A are fixed.

[0035] Each of the pair of first arm members 11A is supported such that the axial centers of the respective first bearing members 11bA are on the same straight line. In a state where each of the pair of first arm members 11A is supported by the first support plate 12A, the surfaces of the respective first arm members 11A in which the respective first shaft support portions 11cA are formed face each other.

[0036] Each of the pair of first roll support portions 20A includes a first roll support body 21A, a first moving body 22A, and a first spring 23A that applies a force to the first moving body 22A in a direction away from the first roll support body 21A. Each of the pair of first roll support portions 20A has an axial center.

[0037] The first roll support body 21A is provided with a first cup portion 21aA and a first shaft portion 21bA that penetrates the first cup portion 21aA. The shape of the first cup portion 21aA is a cup shape. The first cup portion 21aA has an axial center.

[0038] The shape of the first shaft portion 21bA is a rod shape. The first shaft portion 21bA has an axial center. The axial center of the first cup portion 21aA and the axial center of the first shaft portion 21bA are arranged on the same straight line.

[0039] The shape of the first moving body 22A is a rod shape. The first moving body 22A has an axial center. At one end in the axial center direction of the first moving body 22A, a first tip portion 22aA having a tip tapered shape is formed. At the end of the first moving body 22A opposite to the tip portion, a first insertion hole 22bA is formed. The first insertion hole 22bA is formed along the axial center of the first moving body 22A.

[0040] The shape of the first spring 23A is a spiral shape. Since the first spring 23A is in a spiral shape, a hole-shaped space is formed in the first spring 23A.

[0041] The first spring 23A is housed in the first cup portion 21aA. In a state where the first spring 23A is housed in the first cup portion 21aA, the first shaft portion 21bA is inserted into the hole-shaped space of the first spring 23A.

[0042] With the first spring 23A housed in the first cup portion 21aA, the first moving body 22A is housed in the first cup portion 21aA. The first shaft portion 21bA is inserted into the first insertion hole 22bA.

[0043] With the first spring 23A and the first moving body 22A housed in the first cup portion 21aA, anti-disengagement measures are implemented between the first roll support main body 21A and the first moving body 22A.

[0044] In each of the pair of first roll support portions 20A, the first moving body 22A is movable relative to the first roll support main body 21A along the axis of the first roll support portion 20A. The first moving body 22A receives a force in a direction away from the first roll support main body 21A from the first spring 23A.

[0045] Relative rotational movement between the first roll support main body 21A and the first moving body 22A is prevented by a rotation prevention mechanism (not shown).

[0046] The end portions of each first shaft portion 21bA are rotatably supported by corresponding first shaft support portions 11cA via first bearing members 11bA.

[0047] Figure 6 is a cross-sectional view taken along line VI-VI of Figure 5. The first rotation control mechanism 30A includes a first reverse prevention mechanism 31A which is a reverse prevention mechanism, a first stopper mechanism 32A which is a stopper mechanism, and a first housing 33A supported by the first support mechanism 10A.

[0048] The first reverse prevention mechanism 31A includes a first gear 31aA that is integrally fixed and supported on at least one of the pair of first shaft portions 21bA, and a first leaf spring 31bA fixed to the first housing 33A.

[0049] The first gear 31aA has an axis. The axis of the first gear 31aA and the axis of the first shaft portion 21bA are on the same line, and the first gear 31aA is supported by the first shaft portion 21bA. Therefore, the first gear 31aA rotates around the axis of the first shaft portion 21bA integrally with the first shaft portion 21bA.

[0050] The shape of the first leaf spring 31bA is curved in the longitudinal direction. The tip of the first leaf spring 31bA in the longitudinal direction is arranged toward the first gear 31aA.

[0051] When the first gear 31aA rotates in the first direction, which is the A direction in the figure, the first leaf spring 31bA elastically deforms and passes over each tooth of the first gear 31aA. Therefore, the rotation of the first gear 31aA in the first direction is allowed. That is, the rotation of the first shaft portion 21bA and the first roll support portion 20A having the first shaft portion 21bA in the first direction is allowed.

[0052] When the first gear 31aA rotates in the second direction, which is the B direction in the figure, the tip of the first leaf spring 31bA hits the root of the tooth of the first gear 31aA, thereby preventing the rotation of the first gear 31aA in the second direction. That is, the rotation of the first shaft portion 21bA and the first roll support portion 20A having the first shaft portion 21bA in the second direction is prevented.

[0053] The first stopper mechanism 32A includes a first gear 31aA that is integrally fixed and supported on at least one of the pair of first shaft portions 21bA, a first operation portion 34A as an operation portion that is rotatably supported with respect to the first housing 33A, and a first operation portion 35A as an operation portion that is rotatably supported with respect to the first housing 33A.

[0054] In this embodiment, the first reverse prevention mechanism 31A and the first stopper mechanism 32A share and use the first gear 31aA. However, it is not limited to this. Separate gears may be prepared for the first reverse prevention mechanism 31A and the first stopper mechanism 32A.

[0055] The first operation unit 34A includes a first operation unit main body 34aA, a first protrusion 34bA supported by the first operation unit main body 34aA, and a spring (not shown).

[0056] The first operation unit main body 34aA is provided with a first operation unit rotation shaft 34cA, which is a rotation shaft, between both ends in the longitudinal direction. The first operation unit main body 34aA is rotatable around the first operation unit rotation shaft 34cA with respect to the first housing 33A. The axial direction of the first operation unit rotation shaft 34cA is parallel to the axial direction of the first shaft portion 21bA.

[0057] A hole (not shown) is formed at the tip of the first operation unit main body 34aA. A spring and the first protrusion 34bA for accommodating the spring in the hole are inserted into the hole at the tip of the first operation unit main body 34aA.

[0058] The spring is inserted into the hole in a state of applying a force in the direction of protruding the first protrusion 34bA from the hole.

[0059] In a state where the first protrusion 34bA is inserted into the first operation unit main body 34aA, the first protrusion 34bA is provided with an anti-falling process (not shown) so as to be movable along the center line of the hole and not fall out of the hole.

[0060] Therefore, the first protrusion 34bA can protrude or retract with respect to the first operation unit main body 34aA, and receives a force in the direction of protruding from the first operation unit main body 34aA.

[0061] The first operation part 35A has a first operation part main body 35aA. The shape of the first operation part main body 35aA is a rod shape. A first operation part rotation shaft 35cA, which is a rotation shaft, is provided between both ends in the longitudinal direction of the first operation part main body 35aA. The first operation part main body 35aA is rotatable around the first operation part rotation shaft 35cA with respect to the first housing 33A.

[0062] The axial direction of the first operation part rotation shaft 35cA is parallel to the axial direction of the first shaft part 21bA. A first claw part 35bA is formed at one end of the first operation part main body 35aA. The first operation part main body 35aA is supported such that the first claw part 35bA faces the first gear 31aA.

[0063] Based on the position of the first operation part main body 34aA, the first gear 31aA is in a rotating state or a stopped state. That is, based on the state of the first operation part 34A, by operating the first operation part 35A, the rotation around the axis of the first film roll 40A can be controlled.

[0064] FIG. 6 shows a rotating state in which the rotation of the first gear 31aA is permitted. In FIG. 6, a state in which the rear end part of the first operation part main body 34aA has moved from the left side to the right side in the figure is shown. At this time, a first protruding part 34bA beyond the first operation part rotation shaft 34cA from the rear end part of the first operation part main body 34aA has moved from the right side to the left side in the figure. As a result, the other end part of the first operation part main body 35aA is being pushed.

[0065] When the other end part of the first operation part main body 35aA is pushed, the first operation part main body 35aA rotates around the first operation part rotation shaft 35cA, and the first claw part 35bA moves away from the first gear 31aA. Therefore, the first gear 31aA becomes rotatable around its axis, and a rotating state in which the rotation of the first gear 31aA is permitted is achieved.

[0066] FIG. 7 is a cross-sectional view showing a state in which the position of the first operation part 34A in FIG. 6 is changed. FIG. 7 shows a stopped state in which the rotation of the first gear 31aA is blocked.

[0067] Figure 7 shows a state in which the rear end of the first operation unit main body 34aA has moved from the right side to the left side in the drawing. At this time, the first protruding portion 34bA located beyond the first operation unit rotation shaft 34cA from the rear end of the first operation unit main body 34aA is moving from the left side to the right side in the drawing. As a result, one end side of the first operation unit main body 35aA is pushed.

[0068] When one end side of the first operation unit main body 35aA is pushed, the first operation unit main body 35aA rotates around the first operation unit rotation shaft 35cA, and the first claw portion 35bA hits the first gear 31aA. Therefore, the first gear 31aA cannot rotate around its axis, and the rotation of the first gear 31aA is suppressed to a stopped state.

[0069] Returning to FIGS. 6 and 7, the description will continue. When the first operation unit main body 34aA rotates around the first operation unit rotation shaft 34cA, the first protruding portion 34bA reaches a position corresponding to the first operation unit rotation shaft 35cA. At this time, the portion of the first operation unit main body 35aA corresponding to the first operation unit rotation shaft 35cA applies a force in the direction of immersing the first protruding portion 34bA.

[0070] As a result, the first protruding portion 34bA is immersed in the hole of the first operation unit main body 34aA. When the first protruding portion 34bA exceeds the position corresponding to the first operation unit rotation shaft 35cA, the force in the direction of immersing the first protruding portion 34bA by the portion of the first operation unit main body 35aA corresponding to the first operation unit rotation shaft 35cA disappears. As a result, the first protruding portion 34bA protrudes.

[0071] As a result, the operator can intentionally apply force to change the position of the first operation unit main body 34aA. That is, the position of the first operation unit main body 34aA cannot be changed unless force is applied until the first operation unit main body 34aA rotates.

[0072] Returning to FIG. 5, the description will be continued. The first film roll 40A has a first core material 41A and a first cage film 50A as a cage film wound around the first core material 41A. The shape of the first core material 41A is a hollow cylindrical shape. The first core material 41A has an axis. The material of the first core material 41A does not need to be particularly specified, but for example, materials such as paper, resin, and metal can be used.

[0073] The first cage film 50A is a long sheet that can cover a first protection target area 112a set on the first inner surface 111a of the cage 101. The first cage film 50A is transparent. The first cage film 50A is supported by a pair of first roll support portions 20A in a state of being wound around the first core material 41A. The first protection target area 112a will be described later.

[0074] In the first cage film 50A, one end in the longitudinal direction is defined as a first tip portion 50bA as the tip portion, and the end in the longitudinal direction of the first cage film 50A on the side opposite to the first tip portion 50bA is defined as a first base end portion as the base end portion. The first cage film 50A is wound around the first core material 41A from the first base end portion. The first film roll 40A is formed by winding the first cage film 50A around the first core material 41A into a roll shape.

[0075] Each first roll support portion 20A is supported by a first support mechanism 10A such that the respective axes are located on the same straight line. A first film roll 40A is supported between a pair of opposing first moving bodies 22A. A pair of opposing first moving bodies 22A are pushed by a first spring 23A corresponding to the direction in which they face each other.

[0076] The first film roll 40A is supported by being sandwiched between a pair of opposing first moving bodies 22A. In a state where a pair of opposing first moving bodies 22A sandwich the first film roll 40A, the first tip portions 22aA of the respective first moving bodies 22A are fitted into the holes of the first core material 41A.

[0077] The first film roll 40A is detachable from the pair of first roll support portions 20A by changing the distance between the pair of opposing first moving bodies 22A. Therefore, the first film roll 40A is detachable from the first support mechanism 10A.

[0078] As a result, the first film roll 40A is supported by the first support mechanism 10A so as to be rotatable about the axis of the first film roll 40A. The first film roll 40A rotates together with the pair of first roll support portions 20A.

[0079] FIG. 8 is a schematic view showing a state in which the first cage film 50A in FIG. 2 is arranged at the first protection position as the protection position.

[0080] The first cage film 50A is drawn out from the first film roll 40A, passes through the first opening 110ah, and is arranged at the first protection position. The first cage film 50A is fed out from the first film roll 40A, and the first leading end portion 50bA of the first cage film is located at the lower end portion of the first inner surface 111a inside the cage 101.

[0081] The feeding direction, which is the direction in which the first cage film 50A is fed out, is a direction along the longitudinal direction of the first cage film 50A. That is, the first support mechanism 10A supports the first cage film 50A so as to be fed out to the first protection position by the movement of the first leading end portion 50bA in a direction away from the first support mechanism 10A.

[0082] The first protection position is a position where the first cage film 50A fed out from the first support mechanism 10A covers the first protection target area 112a. That is, in a state where the first cage film 50A is located at the first protection position, the first protection target area 112a is covered by the first cage film 50A.

[0083] The first protected target area 112a is an area set on the first inner surface 111a. The first protected target area 112a is appropriately set based on information such as the contamination status of the first inner surface 111a. The first protected target area 112a is protected from contamination by being covered with the first cage film 50A.

[0084] The first cage film 50A is being fed out along the height direction of the first inner surface 111a of the cage 101. Therefore, the height direction of the first inner surface 111a of the cage 101 and the feeding direction of the first cage film 50A are in the same direction.

[0085] The length of the first cage film 50A in the longitudinal direction is twice or more the length of the first inner surface 111a of the cage 101 in the height direction.

[0086] On the first cage film 50A, a plurality of first cutting auxiliary lines 51aA as a plurality of cutting auxiliary lines are formed along the direction orthogonal to the longitudinal direction of the first cage film 50A, that is, along the width direction of the first cage film 50A.

[0087] The first cage film 50A has a first film body 51A and a plurality of first attachment members 52A as a plurality of attachment members attached to one surface of the first film body 51A. A plurality of first cutting auxiliary lines 51aA are formed along the direction orthogonal to the longitudinal direction of the first film body 51A, that is, along the width direction of the first film body 51A.

[0088] The distance between two adjacent first cutting auxiliary lines 51aA along the longitudinal direction of the first film body 51A is equal to the distance of the height direction of the first inner surface 111a of the cage 101. Further, the distance between the first tip portion 50bA of the first cage film 50A and the first cutting auxiliary line 51aA closest to the first tip portion 50bA is equal to the distance of the height direction of the first inner surface 111a of the cage 101.

[0089] Between two adjacent first cutting auxiliary lines 51aA, there are formed a first panel cutting auxiliary line 51bA which is one of the first equipment cutting auxiliary lines for equipment and a first handrail cutting auxiliary line 51cA which is a type of the first equipment cutting auxiliary line. Further, between the first tip portion 50bA of the first basket film 50A and the first cutting auxiliary line 51aA, and between the first cutting auxiliary line 51aA and the rear end portion of the first basket film 50A, the first panel cutting auxiliary line 51bA and the first handrail cutting auxiliary line 51cA are respectively formed.

[0090] When the first film main body 51A between two adjacent first cutting auxiliary lines 51aA is taken as a first film sheet, the positions and shapes of the first equipment cutting auxiliary lines formed on each first film sheet are the same positions and shapes in all the first film sheets. Further, the first film main body 51A between the first tip portion 50bA of the first basket film 50A and the first cutting auxiliary line 51aA, and between the first cutting auxiliary line 51aA and the rear end portion of the first basket film 50A can also be added to the first film sheet.

[0091] The first cutting auxiliary line 51aA and the first equipment cutting auxiliary line are lines connecting the portions where the first film main body 51A is intermittently cut in a broken line shape along the first cutting auxiliary line 51aA and the first equipment cutting auxiliary line.

[0092] The plurality of first attachment members 52A are magnets. Each first attachment member 52A is arranged in a first tip region 51dA which is a tip region of the first film main body 51A. The first tip region 51dA is a region extending from the first tip portion 50bA of the first film main body 51A and the first cutting auxiliary line 51aA toward the end portion on the side opposite to the first tip portion 50bA of the first film main body 51A. That is, the first tip region 51dA is a region on the first film main body 51A having a certain width along the first tip portion 50bA of the first film main body 51A or the first cutting auxiliary line 51aA.

[0093] In this embodiment, three first attachment members 52A are arranged in one first tip region 51dA. However, the number of the first attachment members 52A provided in one first tip region 51dA can be set as appropriate.

[0094] In this embodiment, the length of the first tip region 51dA in the direction along the longitudinal direction of the first film body 51A is 10 cm. The length of the first tip region 51dA along the longitudinal direction of the first film body 51A can be set as appropriate, and for example, it may be within 10 cm or within 15 cm.

[0095] In each of the plurality of first tip regions 51dA, first connection holes 51eA, which are two connection parts, are formed. The first connection holes 51eA are holes provided in the first tip regions 51dA.

[0096] In this embodiment, two first connection holes 51eA are arranged in one first tip region 51dA. However, the number of the first connection holes 51eA provided in one first tip region 51dA can be set as appropriate.

[0097] A drawing tool (not shown) having a hook-shaped tip can be hooked on the first connection hole 51eA. An operator can hook the tip of the drawing tool on the first connection hole 51eA from inside the basket 101 and draw out the first basket film 50A into the basket 101.

[0098] The first tip portion 50bA of the first basket film 50A drawn out to the first protection position is connected to the first inner surface 111a of the basket 101 by the magnetic force of the first attachment member 52A.

[0099] FIG. 9 is a schematic view showing a state in which the first basket film 50A in FIG. 8 is cut based on the first equipment cutting auxiliary line. The position of the first film body 51A corresponding to the positions of the operation panel 115 and the handrail 116 is cut and removed.

[0100] The cutting auxiliary line 51bA for the first panel is formed not only at positions other than the position of the first film body 51A corresponding to the operation panel 115. An operator can cut the first film body 51A along the corresponding cutting auxiliary line 51bA for the first panel based on the position and shape of the corresponding operation panel. As a result, the first cage film 50A can correspond to a plurality of cages 101 with different arrangement positions or shapes of the operation panel.

[0101] The cutting auxiliary line 51cA for the first handrail is formed not only at positions other than the position of the first film body 51A corresponding to the handrail 116. An operator can cut the first film body 51A along the corresponding cutting auxiliary line 51cA for the first handrail based on the position and shape of the corresponding handrail. As a result, the first cage film 50A can correspond to a plurality of cages 101 with different arrangement positions or shapes of the handrail.

[0102] Next, the replacement of the first cage film 50A installed at the first protection position will be described. The first cage film 50A installed at the first protection position gets dirty when the elevator 100 is used. The dirt is caused by things such as dust floating in the environment, droplets from people, and scratches when hit by the belongings of the passengers of the elevator 100.

[0103] An operator who is the administrator of the elevator 100 can replace the first cage film 50A installed at the first protection position based on the dirt situation.

[0104] First, the first cage film 50A installed at the first protection position is discarded. To discard the first cage film 50A installed at the first protection position, the operator cuts the first film body 51A along the first cutting auxiliary line 51aA located near the first opening 110ah.

[0105] The first film body 51A of the portion that was installed at the cut-off first protection position is appropriately processed by means such as disposal. A new first tip 50bA as a new tip portion is formed on the first film body 51A by cutting.

[0106] Two first connection holes 51eA are pre-formed in the first tip region 51dA along the first cutting auxiliary line 51aA of the new first tip 50bA. The operator hooks a pulling tool on the first connection hole 51eA and pulls out the first cage film 50A from the first opening 110ah.

[0107] At this time, the operator operates the first operation unit main body 34aA to position the first operation unit main body 34aA at a position where rotation of the first roll support unit 20A in the first direction is allowed. Thereby, the first film roll 40A supported by the first roll support unit 20A can rotate in the first direction around the axis of the first film roll 40A.

[0108] The first direction is the direction in which the first film roll 40A rotates when the first cage film 50A is pulled out from inside the cage 101. That is, the first direction is the direction in which the first cage film 50A is fed into the inside of the cage 101.

[0109] The first cage film 50A having the pulled-out new first tip 50bA is arranged at the first protection position. The first cage film 50A having the new first tip 50bA arranged at the first protection position can be connected to the lower end portion of the first inner surface 111a of the cage 101 by the magnetic force of the first attachment member 52A provided at the new first tip 50bA.

[0110] After the first cage film 50A having the newly drawn first tip portion 50bA is disposed at the first protection position, the operator operates the first operation unit main body 34aA and positions the first operation unit main body 34aA at a position where the rotation of the first roll support unit 20A in the first direction is blocked. Thereby, the first film roll 40A supported by the first roll support unit 20A cannot rotate in the first direction about the axis of the first film roll 40A.

[0111] With the first cage film 50A having the newly drawn first tip portion 50bA disposed at the first protection position, the operator cuts the first cage film 50A along any of the first facility cutting lines in order to remove the first cage film 50A at a position corresponding to the operation panel 115 and the handrail 116.

[0112] Thereby, the replacement of the old first cage film 50A installed at the first protection position with the new first cage film 50A is completed.

[0113] The replacement of the old first cage film 50A installed at the first protection position with the new first cage film 50A can be carried out a plurality of times until the first cage film 50A wound as the first film roll 40A runs out.

[0114] When the first cage film 50A wound as the first film roll 40A runs out, a new first film roll 40A can be replenished and the film device 1 can be used. The new first film roll 40A is a first film roll 40A with a new first cage film 50A wound thereon. To replenish the new first film roll 40A, the first core material 41A is removed from the first roll support unit 20A.

[0115] The second film unit 3B is disposed outside the cage 101 and above the second side wall 110b. The second cage film 50B is disposed at a second protection position covering a second protected area (not shown) through the second opening 110bh. The second cage film disposed at the second protection position covers the second protected area (not shown) of the second inner surface 111b.

[0116] The second film unit 3B is different from the configuration of the first film unit 3A in the above points. Therefore, in the description of the first film unit 3A above, the description in which the prefix "first" is replaced with "second" and the suffix "A" of the reference numeral is replaced with "B" shall be the description of the second film unit 3B. Also, in the description of the first film unit 3A above, the description in which "the first side wall 110a" is replaced with "the second side wall 110b" and "the first inner surface 111a" is replaced with "the second inner surface 111b" shall be the description of the second film unit 3B. Further, in the description of the first film unit 3A above, the description in which "the first protected area 112a" is replaced with "the second protected area" and "the first opening 110ah" is replaced with "the second opening 110bh" shall be the description of the second film unit 3B.

[0117] According to the film device 1 according to Embodiment 1, it includes a film mechanism 2 having a first film unit 3A. The first film unit 3A has a first car film 50A and a first support mechanism 10A supported by the car 101 of the elevator 100. Further, the first car film 50A has a base end portion which is one end portion in the longitudinal direction of the first car film 50A and a first tip portion 50bA which is an end portion opposite to the base end portion. Further, the first support mechanism 10A supports the first car film 50A so that it can be sent out to a first protection position which is a position covering a first protection target area 112a set on the first inner surface 111a of the car 101 when the first tip portion 50bA moves in a direction away from the first support mechanism 10A. Also, the feeding direction, which is the direction in which the first car film 50A is fed out, is a direction along the longitudinal direction of the first car film 50A. Further, the first car film 50A is cut at a position between a first base end portion (not shown) and the first tip portion 50bA of the first car film 50A arranged at the first protection position. Also, it is cut in a direction intersecting the longitudinal direction of the first car film 50A, and an end portion opposite to the first base end portion in the longitudinal direction of the first car film 50A having the first base end portion is made into a new first tip portion 50bA. At this time, the first support mechanism 10A can send out the first car film 50A having the new first tip portion 50bA to the first protection position. Thereby, the first car film 50A arranged at the first protection position can be cut and removed, and a new first car film 50A can be arranged at the first protection position. Therefore, the replacement of the first car film 50A can be easily carried out. Thereby, the contaminated first car film 50A can be cut and removed, and a new first car film 50A can be arranged at the first protection position. Therefore, the replacement of the first car film 50A can be easily carried out, and the inside of the car 101 can be kept clean. Thereby, the first inner surface 111a can be protected by the first car film 50A. Therefore, the first inner surface 111a can be maintained in a clean state. Thereby, the number of orders for the new first car film 50A can be reduced. Therefore, it is possible to shorten the lead time and reduce the labor cost of the personnel involved in the arrangement.As a result, there is no need to bring the new first car film 50A into the car 101. Therefore, the labor for replacing the first car film 50A can be reduced, and the replacement of the first car film 50A can be easily carried out. Thus, the replacement work of the first car film 50A can be carried out by a single operator. Therefore, the replacement of the first car film 50A can be easily carried out. Furthermore, since the replacement of the first car film 50A can be easily carried out, the replacement work can also be performed by persons other than specifically designated operators, such as employees in the building and passengers in the elevator 100.

[0118] According to the film device 1 according to the first embodiment, the first support mechanism 10A cuts between the first base end portion and the first tip end portion 50bA of the first car film 50A disposed at the first protection position in a direction intersecting the longitudinal direction of the first car film 50A. Further, it is possible to repeatedly perform feeding out the first car film 50A having the new first tip end portion 50bA formed thereby to the first protection position. Thereby, multiple replacement operations can be performed with the first car film 50A. Therefore, the replacement of the first car film 50A can be easily carried out. Thereby, the number of orders for the new first car film 50A can be further reduced. Therefore, the lead time and the labor cost of the personnel involved in the arrangement can be further reduced. As a result, there is no longer a need to bring the new first car film 50A into the car 101. Therefore, the labor for replacing the first car film 50A can be further reduced, and the replacement of the first car film 50A can be more easily carried out.

[0119] According to the film device 1 according to Embodiment 1, the length of the first cage film 50A in the longitudinal direction is more than twice the length of the inner surface of the cage 101 in the direction along the feeding direction of the first cage film 50A. Thereby, a plurality of replacement operations can be carried out with the first cage film 50A. Therefore, the replacement of the first cage film 50A can be easily carried out. Thereby, the number of orders for the new first cage film 50A can be further reduced. Therefore, the lead time and the labor cost of the personnel involved in the arrangement can be further reduced. Thereby, it becomes less necessary to bring the new first cage film 50A into the cage 101. Therefore, the labor for replacing the first cage film 50A can be further reduced, and the replacement of the first cage film 50A can be more easily carried out.

[0120] According to the film device 1 according to Embodiment 1, one or more first cutting auxiliary lines 51aA are formed on the first cage film 50A along the direction orthogonal to the feeding direction of the first cage film 50A. Thereby, the first cage film 50A can be more easily cut. Therefore, the replacement of the first cage film 50A can be easily carried out. Thereby, the cutting position of the first cage film 50A can be cut without hesitation, and the cutting operation can be more easily carried out. Therefore, the replacement of the first cage film 50A can be easily carried out.

[0121] According to the film device 1 according to Embodiment 1, a first attachment member 52A is installed on the first cage film 50A. Further, the first attachment member 52A can fix the first cage film 50A inside the cage 101. Further, the first attachment member 52A is installed in the first tip region 51dA of the first cage film 50A up to 10 cm from each first cutting auxiliary line 51aA toward the first base end. Thereby, the first cage film 50A arranged at the first protection position can be easily fixed to the first inner surface 111a. Therefore, the replacement of the first cage film 50A can be easily carried out.

[0122] According to the film device 1 according to Embodiment 1, a first connection hole 51eA is formed in the first cage film 50A. Further, the first connection hole 51eA is a portion where a drawing tool can be connected to the first connection hole 51eA to draw out the first cage film 50A into the cage 101. Further, the first connection hole 51eA is formed in each of the first tip regions 51dA of the first cage film 50A from one or more first cutting auxiliary lines 51aA toward the first base end portion for up to 10 cm. Thereby, the first cage film 50A can be easily drawn out. Therefore, the replacement of the first cage film 50A can be easily carried out.

[0123] According to the film device 1 according to Embodiment 1, one or more first equipment cutting auxiliary lines having a shape corresponding to the equipment inside the cage installed on the first inner surface 111a are formed in the first cage film 50A. Thereby, the first cage film 50A corresponding to the positions of the equipment installed in the cage 101, such as the operation panel 115 and the handrail 116, can be cut and removed. Therefore, the equipment installed on the first inner surface 111a protected by the first cage film 50A can be appropriately used. Thus, a comfortable and safer environment can be provided by the cage 101.

[0124] According to the film device 1 according to Embodiment 1, the first film unit 3A further includes a first rotation control mechanism 30A, and the first rotation control mechanism 30A has a first reverse prevention mechanism 31A. Further, the first support mechanism 10A supports the first film roll 40A, and the first film roll 40A is the first cage film 50A wound from the first base end portion to the first tip end portion 50bA of the first cage film 50A. Further, the first film roll 40A is rotatable about the axis of the first film roll 40A. Further, the first reverse prevention mechanism 31A allows rotation in the first direction, which is the direction in which the first cage film 50A is fed out into the cage 101, during rotation of the first film roll 40A about its axis. Also, rotation in the second direction, which is the rotation direction opposite to the first direction, is blocked. Thereby, the first film unit 3A can hold a large amount of the first cage film 50A. Thereby, the number of orders for the new first cage film 50A can be further reduced. Therefore, the arrangement time and the labor cost of the personnel involved in the arrangement can be further reduced. Thereby, the need to bring the new first cage film 50A into the cage 101 can be further eliminated. Therefore, the labor for replacing the first cage film 50A can be further reduced, and the replacement of the first cage film 50A can be easily carried out. Thereby, the first film roll 40A does not rotate in the second direction. Therefore, the replacement work of the first cage film 50A becomes easier without the first cage film 50A being wound around the first film roll 40A. Therefore, the labor for replacing the first cage film 50A can be further reduced.

[0125] According to the film device 1 according to Embodiment 1, the first rotation control mechanism 30A further includes a first stopper mechanism 32A. The first stopper mechanism 32A has a first operation portion 34A and a first operation portion 34A and a first operation portion 35A. Further, the first stopper mechanism 32A can prevent rotation in the first direction by the first operation portion 35A moving based on the state of the first operation portion 34A. Thereby, the rotation of the first film roll 40A can be controlled by operating the first operation portion 34A. Therefore, the rotation of the first film roll 40A in the first direction can be allowed only when it is necessary to pull out the first car film 50A. Thus, the first car film 50A is not inadvertently pulled into the car 101, and waste of the first car film 50A is eliminated.

[0126] According to the film device 1 according to Embodiment 1, the first support mechanism 10A is supported above the inner ceiling plate 102e of the car 101. Further, a first opening 110ah through which the first car film 50A passes is formed in the inner ceiling plate 102e, and the feeding direction of the first car film 50A is a direction along the height direction of the first inner surface 111a. Thereby, the first support mechanism 10A is not visible to the users of the elevator 100. Therefore, it is less likely to affect the design inside the car 101 even when the film device 1 is used. As a result, it is less likely for the users of the elevator 100 to notice the existence of the first opening 110ah. Therefore, it is less likely to affect the design inside the car 101 even when the film device 1 is used. Thereby, the first car film 50A is pulled out from above downward. Therefore, the first car film 50A can be pulled out by utilizing the force of gravity. Thus, the replacement of the car film can be easily carried out.

[0127] According to the film device 1 according to Embodiment 1, the film mechanism 2 further includes a second film unit 3B. The second film unit 3B has a second cage film 50B and a second support mechanism 10B supported by the cage 101. The second cage film 50B has a second base end portion which is one end portion in the longitudinal direction of the second cage film 50B and a second tip end portion 50bB which is an end portion opposite to the second base end portion. The second support mechanism 10B supports the second cage film 50B so that it can be fed out to a second protection position which is a position covering a second protection target area set on the second inner surface 111b of the cage 101 when the second tip end portion 50bB moves in a direction away from the second support mechanism 10B. The feeding direction, which is the direction in which the second cage film 50B is fed out, is a direction along the longitudinal direction of the second cage film 50B. The second cage film 50B is cut in a direction intersecting the longitudinal direction of the second cage film 50B at a position between the second base end portion and the second tip end portion 50bB of the second cage film 50B arranged at the second protection position, and an end portion opposite to the second base end portion in the longitudinal direction of the second cage film 50B having the second base end portion is made into a new second tip end portion 50bB. At this time, the second support mechanism 10B can feed out the second cage film 50 having the new second tip end portion 50bB to the second protection position. The second protection target area is an area different from the first protection target area 112a. Thereby, two inner surfaces in the cage 101 can be covered. Therefore, the two inner surfaces can be protected. Therefore, more specifically, the second cage film 50B arranged at the second protection position can be cut and removed, and a new second cage film 50B can be arranged at the second protection position. Therefore, the replacement of the first cage film 50A and the second cage film 50B can be easily carried out. Thereby, the contaminated first cage film 50A and the second cage film 50B can be cut and removed, and new first cage film 50A and second cage film 50B can be arranged. Therefore, the replacement of the first cage film 50A and the second cage film 50B can be easily carried out, and the inside of the cage 101 can be kept clean.As a result, it is possible to protect the first protected area 112a of the first inner surface 111a and the second protected area of the second inner surface 111b. Therefore, the first inner surface 111a and the second inner surface 111b can be maintained in a clean state. As a result, the order frequency of the new first cage film 50A and the second cage film 50B can be reduced. Therefore, it is possible to shorten the lead time and reduce the labor cost of the personnel involved in the arrangement. As a result, it is not necessary to bring the new first cage film 50A and the second cage film 50B into the cage 101. Therefore, the labor for replacing the first cage film 50A and the second cage film 50B can be reduced, and the replacement of the first cage film 50A and the second cage film 50B can be easily carried out. As a result, the replacement work of the first cage film 50A and the second cage film 50B can be carried out by one operator. Therefore, the replacement of the first cage film 50A and the second cage film 50B can be easily carried out. Furthermore, since the replacement of the first cage film 50A and the second cage film 50B can be easily carried out, the replacement work can also be performed by persons other than the specifically designated operator, for example, employees in the building, passengers in the elevator 100, and the like.

[0128] Note that according to the first embodiment, a plurality of cutting lines for the first equipment were formed on the first cage film 50A. However, the present invention is not limited to this. One cutting line for the first equipment may be formed on the first cage film 50A.

[0129] Embodiment 2. FIG. 10 is a schematic view showing a state in which the first cage film 50A in the second embodiment is disposed at the first protection position. In the film device 1 of the second embodiment, the formation position of the cutting auxiliary line formed on the cage film is different from that of the film device 1 of the first embodiment. Since the configuration of the film device 1 of the second embodiment other than the above is the same as the configuration of the film device 1 of the first embodiment, the description thereof will be omitted.

[0130] The first film body 51A is formed with a plurality of first cutting auxiliary lines 51aA and a plurality of first longitudinal cutting auxiliary lines 51fA which are longitudinal cutting auxiliary lines. The first longitudinal cutting auxiliary lines 51fA are formed along the longitudinal direction of the first cage film 50A.

[0131] The distance between two adjacent first cutting auxiliary lines 51aA is shorter than the length in the height direction of the first inner surface 111a of the cage 101. Further, the distance between the first tip 50bA of the first cage film 50A and the first cutting auxiliary line 51aA closest to the first tip 50bA is shorter than the length in the height direction of the first inner surface 111a of the cage 101.

[0132] The first cutting auxiliary lines 51aA and the first longitudinal cutting auxiliary lines 51fA are lines connecting the portions where the first film body 51A is intermittently cut in a broken line shape.

[0133] FIG. 11 is a schematic view showing a state in which the first cage film 50A of FIG. 10 is cut based on the first cutting auxiliary lines 51aA and the first longitudinal cutting auxiliary lines 51fA. A part of the first film body 51A corresponding to the positions of the operation panel 115 and the handrail 116 is cut and removed.

[0134] In the first cage film 50A arranged at the first protection position, the portion of the first cage film 50A corresponding to the positions corresponding to the operation panel 115 and the handrail 116 is removed. The operator cuts the first cage film 50A along any of the first cutting auxiliary lines 51aA and the first longitudinal cutting auxiliary lines 51fA.

[0135] Thereby, the replacement of the old first cage film 50A installed at the first protection position with a new first cage film 50A is completed.

[0136] The replacement of the old first cage film 50A installed at the first protection position with a new first cage film 50A can be carried out multiple times until the first cage film 50A wound as the first film roll 40A runs out.

[0137] When the first cage film 50A wound as the first film roll 40A runs out, a new first film roll 40A can be replenished and the film device 1 can be used. The new first film roll 40A is a first film roll 40A with a new first cage film 50A wound thereon. To replenish the new first film roll 40A, the first core 41A is removed from the first roll support 20A for implementation.

[0138] Since the replacement of the first cage film 50A in the second embodiment is carried out in the same manner as the replacement of the first cage film 50A in the first embodiment, the description thereof is omitted.

[0139] The second film unit 3B is disposed outside the cage 101 and above the second side wall 110b. The second cage film 50B is disposed at a second protection position covering a second protection target area (not shown) through the second opening 110bh. The second cage film disposed at the second protection position (not shown) covers the second protection target area of the second inner surface 111b.

[0140] The second film unit 3B is different from the configuration of the first film unit 3A in the above points. Therefore, in the description of the first film unit 3A described above, the description in which the prefix "first" is replaced with "second" and the suffix "A" at the end of the reference numeral is replaced with "B" shall be the description of the second film unit 3B. Also, in the description of the first film unit 3A described above, the description in which "the first side wall 110a" is replaced with "the second side wall 110b" and "the first inner surface 111a" is replaced with "the second inner surface 111b" shall be the description of the second film unit 3B. Further, in the description of the first film unit 3A described above, the description in which "the first protection target area 112a" is replaced with "the second protection target area" and "the first opening 110ah" is replaced with "the second opening 110bh" shall be the description of the second film unit 3B.

[0141] According to the film device 1 according to the second embodiment, the distance between two adjacent first cutting auxiliary lines 51aA is a distance equal to or less than the length of the first inner surface 111a of the basket 101 in the direction along the feeding direction of the film 50A for the first basket. Thereby, the film 50A for the first basket can be cut at an arbitrary position. Therefore, it is possible to correspond to various baskets 101.

[0142] According to the film device 1 according to the second embodiment, a plurality of first longitudinal cutting auxiliary lines 51fA are formed along the longitudinal direction on the film 50A for the first basket. Thereby, the film 50A for the first basket can be cut at an arbitrary position along the longitudinal direction. Therefore, it is possible to correspond to various baskets 101.

[0143] Note that the film device 1 of the first embodiment and the second embodiment has the first film unit 3A and the second film unit 3B. However, the present invention is not limited to this. For example, the film device 1 may have only one film unit. Further, for example, the film device 1 may have only three film units. In this case, each protection target area set on each inner surface of the wall 102a, that is, each of the first inner surface 111a, the second inner surface 111b, and the third inner surface 111c, can be covered with each film for the basket.
