The male thread portion of each screw member 22 is passed through at least one of the upper end through-portion 15c and the lower end through-portion 15d of the protective plate 15 and screwed into the screw hole 12a of the support member 12. The protective plate 15 is sandwiched between the head of the screw member 22 and the support member 12. Each screw member 22 fastens the protective plate 15 and the support member 12. The screw members 22 are, for example, bolts, flat washers, and spring washers. In this case, the male thread portion is the shank of the bolt, the outer surface of the shank has a male thread, and the head is the head of the bolt.
[0040] On one and the other widthwise sides of the opening in the protective member 11, the male threaded portions of the screw members 22 are passed through the upper end through-portions 15c of the protective plate 16 and are screwed into the screw holes 20a. On one and the other widthwise sides of the opening in the protective member 11, the male threaded portions of the screw members 22 are passed through the lower end through-portions 15d of the protective plate 16 and the upper end through-portions 15c of the protective plate 17 and are screwed into the screw holes 20a. On one and the other widthwise sides of the opening in the protective member 11, the male threaded portions of the screw members 22 are passed through the lower end through-portions 15d of the protective plate 17 and the upper end through-portions 15c of the protective plate 18 and are screwed into the screw holes 20a. On one and the other widthwise sides of the entrance in the protective member 11, the male threads of the screw members 22 are passed through the lower end through-portion 15d of the protective plate 18 and the upper end through-portion 15c of the protective plate 19, and are screwed into the screw holes 20a. On one and the other widthwise sides of the entrance in the protective member 11, the male threads of the screw members 22 are passed through the lower end through-portion 15d of the protective plate 19, and are screwed into the screw holes 21a.
[0041] On one side and the other side of the width of the entrance / exit in the upper protective plate 15 and the lower protective plate 15, which are adjacent to each other in the vertical direction, the screw member 22 is passed through the lower end through portion 15d of the upper protective plate 15 and the upper end through portion 15c of the lower protective plate 15, and is screwed into the screw hole 12a.
[0042] Here, the screw hole 12a facing the upper end through-portion 15c of the protective plate 15 is referred to as the upper screw hole of the protective plate 15. The screw hole 12a facing the lower end through-portion 15d of the protective plate 15 is referred to as the lower screw hole of the protective plate 15.
[0043] Each support 20 has an upper screw hole and a lower screw hole in the protective plate 16. Each support 20 has an upper screw hole and a lower screw hole in the protective plate 17.

[0045] Furthermore, the fixed portion 15a of each protective plate 15 is fixed to the support member 12 by the screw member 22, but the flexible portion 15b is not fixed. For this reason, the flexible portion 15b of the protective plate 15 is likely to bend in the depth direction of the entrance due to the wind pressure generated when the car 2 moves up and down inside the hoistway 1. However, because the upper protective plate has the recess 15e, in the upper protective plate 15 and the lower protective plate 15 that are adjacent to each other in the vertical direction, even if at least one of the flexible portion 15b of the upper protective plate 15 and the flexible portion 15b of the lower protective plate 15 bends in the depth direction of the entrance, the flexible portion 15b of the upper protective plate 15 and the flexible portion 15b of the lower protective plate 15 do not come into contact with each other.
[0046] The fixing member 14 has a plurality of fixing devices 23 and a plurality of screw members 24, 25, and 26.

The upper part of fixed portion 15a of protective plate 18 has moved downward relative to the lower part of fixed portion 15a of protective plate 17 and the upper screw member of protective plate 18. The lower part of fixed portion 15a of protective plate 18 remains positioned on the opposite side of wall 1a in the depth direction of the entrance relative to the upper part of fixed portion 15a of protective plate 19 and the lower screw member of protective plate 18. The upper part of flexible portion 15b of protective plate 18 has moved downward relative to the lower part of flexible portion 15b of protective plate 17. The lower part of flexible portion 15b of protective plate 18 remains positioned on the opposite side of wall 1a in the depth direction of the entrance relative to flexible portion 15b of protective plate 19.
[0069] The upper screw member of the protective plate 18 is now disengaged from the upper end through-hole 15c of the protective plate 18. The lower screw member of the protective plate 18 remains disengaged from the lower end through-hole 15d of the protective plate 18.
[0070] The protective plate 18 can move upward within the range of the gap between the upper screw member of the protective plate 18. The protective plate 18 can move downward within the range of the gap between the upper part of the protective plate 19. The upper part of the protective plate 18 can move in the width direction of the entrance. The lower part of the protective plate 18 can move in the width direction of the entrance. The upper part of the protective plate 18 can move in the depth direction of the entrance on the side opposite wall 1a from the support 20. The lower part of the protective plate 18 can move in the depth direction of the entrance on the side opposite wall 1a from the lower end protective plate.
[0071] Figure 10(f) shows a state in which the upper part of protective plate 18 has been moved away from wall 1a from the state shown in Figure 10(e). Figure 10(f) shows a state in which protective plates 17 and 19 are attached to support 20 fixed to wall 1a, and protective plate 18 has been removed from support 20 fixed to wall 1a. The upper part of fixing portion 15a of protective plate 18 has been changed to a state in which it is positioned on the opposite side of wall 1a in the depth direction of the entrance from the lower part of fixing portion 15a of protective plate 17 and the upper screw member of protective plate 18. The lower part of fixing portion 15a of protective plate 18 remains positioned on the opposite side of wall 1a in the depth direction of the entrance from the upper part of fixing portion 15a of protective plate 19 and the lower screw member of protective plate 18. The upper part of flexible portion 15b of protective plate 18 is now positioned on the opposite side of wall 1a in the depth direction of the entrance from the lower part of flexible portion 15b of protective plate 17. The lower part of flexible portion 15b of protective plate 18 remains positioned on the opposite side of wall 1a in the depth direction of the entrance from the upper part of flexible portion 15b of protective plate 19.
[0072] The upper screw member of the protective plate 18 remains disengaged from the upper end through-hole 15c of the protective plate 18. The lower screw member of the protective plate 18 remains disengaged from the lower end through-hole 15d of the protective plate 18.
[0073] The protective plate 18 can move vertically and in the width direction of the entrance. The protective plate 18 can also move in the depth direction of the entrance on the side opposite the wall 1a from the protective plates 17 and 19 and the support 20.
[0074] As described above, in a state in which the protective plates 17 and 19 are attached to the support 20 fixed to the wall 1 a, the protective plate 18 can be attached to and detached from the support 20 .
[0075] When attaching or detaching protective plate 18 to or from support 20, the upper screw member of protective plate 17 and the lower screw member of protective plate 19 may be loosened. This makes it possible to easily widen the gap between protective plate 17 and support 20 in the depth direction of the entrance and the gap between protective plate 19 and support 20 in the depth direction of the entrance and the gap between protective plate 19 and support 20.
[0076] From the above, it is clear that the protective plate 16 can be attached to and detached from the support 20 in a state in which the protective plate 17 is attached to the support 20 fixed to the wall 1a. Because the protective plate 16 is located at the top of the protective member 11, the protective plate 16 can be attached to and detached from the support 20 more easily than the protective plate 18 can be attached to and detached from the support 20 as described above. Note that if the toe protection plate 9c is fixed to the landing threshold 9a of the upper landing 5, the screw member 9d that secures the toe protection plate 9c to the landing threshold 9a may be loosened when attaching or detaching the protective plate 16 to the support 20. This makes it possible to easily widen the gap between the toe protection plate 9c and the protective plate 18 in the depth direction of the entrance / exit.
[0077] Similarly, it is clear that in a state in which the protective plates 16 and 18 are attached to the support fixture 20 fixed to the wall 1a, the protective plate 17 can be attached and detached to the support fixture 20. Since the protective plate 17 is attached to the opposite side of the support fixture 20 from the protective plates 16 and 18, the protective plate 17 can be attached and detached to the support fixture 20 more easily than the protective plate 18 can be attached and detached to the support fixture 20 as described above.
[0078] Similarly, it is clear that in a state in which the protective plate 18 is attached to the support 20 fixed to the wall 1a, the protective plate 19 can be attached to and detached from the support 20 and 21. Since the protective plate 19 is attached to the opposite side of the support 20 from the protective plate 18, the protective plate 19 can be attached to and detached from the support 20 more easily than the protective plate 18 can be attached to and detached from the support 20 as described above.
[0079] In addition, with all the screw members 22 temporarily fastened to the support member 12, the protection plates 16, 17, 18 and 19 can be attached to and detached from the support member 12.
[0080] The elevator entrance protection device in the first embodiment includes a protection member 11 provided between a wall 1a of the hoistway 1 and a car entrance 3 of the car 2, which may face each other when the car 2 ascends and descends inside the hoistway 1, a support member 12 fixed inside the hoistway 1 and supporting the protection member 11, and a joining member 13 joining the protection member 11 and the support member 12, the protection member 11 having a protection plate 15 extending in the vertical direction and in the width direction of the car entrance 3, the protection plate 15 having a pair of upper end through-portion 15c and lower end through-portion 15d, the upper end through-portion 15c being recessed downward from the upper end of the protection plate 15, and the lower end through-portion 15d being recessed upward from the lower end of the protection plate 15, the support member 12 having a plurality of screw holes 12a, the plurality of screw holes 12a being upper screw holes and lower screw holes, The connecting member 13 includes screw holes, the upper screw hole facing the upper end through-portion 15c and the lower screw hole facing the lower end through-portion 15d, the connecting member 13 having an upper screw member and a lower screw member, the upper screw member being passed through the upper end through-portion 15c of the protective plate 15 and screwed into the upper screw hole to fasten the protective plate 15 and the support member 12 together, and the lower screw member being passed through the lower end through-portion 15d of the protective plate 15 and screwed into the lower screw hole to fasten the protective plate 15 and the support member 12 together, and when the upper screw member and the lower screw member are loosened and the protective plate 15 moves upward, the lower screw member comes off the lower end through-portion 15d, and even when the upper screw member and the lower screw member are loosened and the protective plate 15 moves downward, the upper screw member does not come off the upper end through-portion 15c.
[0081] This allows the protective plate 15 to be easily attached to and detached from the support member 12 with the upper screw member and the lower screw member screwed into the support fixture 20. In particular, since the worker can hold the protective plate 15 with both hands to attach and detach it from the support member 12, it is possible to prevent the worker from dropping the protective plate 15 inside the hoistway 1.
[0082] In the elevator entrance / exit protection device of embodiment 1, a landing entrance / exit 6 that can face the car entrance / exit 3 when the car 2 rises or falls is provided on the wall 1a above the protection member 11, and a toe protection plate 9c is provided below the landing entrance / exit 6 inside the elevator shaft 1, and the toe protection plate 9c extends in the vertical direction and in the width direction of the car entrance / exit 3, and the upper part of the protection member 11 is located between the wall 1a and the toe protection plate 9c.
[0083] As a result, even if the vertical distance between the upper landing entrance / exit 6 and the lower landing entrance / exit 6 changes, the entrance / exit protection device 10 can be easily attached without leaving a vertical gap between the protection member 11 and the toe protection plate 9c of the upper landing entrance / exit 6.
[0084] In the elevator entrance protection device in the first embodiment, the upper end penetration portion 15c and the lower end penetration portion 15d of the protection plate 15 are aligned in the vertical direction, the protection member 11 has an upper protection plate 15 and a lower protection plate 15 adjacent to each other in the vertical direction, the lower end penetration portion 15d of the upper protection plate 15 and the upper end penetration portion 15c of the lower protection plate 15 face each other in the depth direction of the car entrance 3, and the screw member 22 is By passing it through the upper end through-hole 15c of the protective plate 15 and screwing it into the screw hole 12a, one of the lower screw member of the upper protective plate 15 and the upper screw member of the lower protective plate 15 doubles as the other, and at the same time, one of the lower screw hole of the upper protective plate 15 and the upper screw hole of the lower protective plate 15 doubles as the other, and when the upper screw member and lower screw member of the upper protective plate 15 are loosened, the upper protective plate 15 can move upward relative to the lower protective plate 15.
[0085] As a result, when the lower protective plate 15 is attached to the support member 12, the upper protective plate 15 can be easily attached and detached without removing the lower protective plate 15. This is particularly effective when the upper protective plate 15 is attached closer to the support member 12 in the depth direction of the car entrance than the lower protective plate 15.
[0086] In the elevator entrance / exit protection device in embodiment 1, the protective plate 15 has a fixed portion 15a and a flexible portion 15b that are aligned in the width direction of the car entrance / exit 3, the fixed portion 15a has an upper end through-portion 15c and a lower end through-portion 15d, the upper protective plate 15 has a recess 15e, and the recess 15e of the upper protective plate 15 is formed by positioning the lower end of the flexible portion 15b of the upper protective plate 15 higher than the lower end of the fixed portion 15a of the upper protective plate 15, and the lower end through-portion 15d of the upper protective plate 15 and the upper end through-portion 15c of the lower protective plate 15 face each other in the depth direction of the car entrance / exit 3, and the flexible portion 15b of the upper protective plate 15 and the flexible portion 15b of the lower protective plate 15 do not face each other in the depth direction of the car entrance / exit.
[0087] As a result, even if at least one of the flexible portion 15b of the upper protective plate 15 and the flexible portion 15b of the lower protective plate 15 bends in the depth direction of the entrance / exit due to the wind pressure generated when the car 2 moves up and down inside the elevator shaft 1, the flexible portion 15b of the upper protective plate 15 and the flexible portion 15b of the lower protective plate 15 do not come into contact with each other, thereby preventing the generation of noise.
[0088] In the elevator entrance protection device of the first embodiment, the upper protection plate 15 may not be formed with the recess 15e, and the upper end of the flexible part 15b of the lower protection plate 15 may be positioned lower than the upper end of the fixed part 15a of the lower protection plate 15, thereby forming a recess. In this case, the same effect can be achieved.
[0089] In the elevator entrance / exit protection device in embodiment 1, the support member 12 includes a support 20 and a support 21, and the support 20 has an upper screw hole and a lower screw hole in the upper protective plate 18 and an upper screw hole in the lower protective plate 19, and the support 21 has a lower screw hole in the lower protective plate 19.
[0090] As a result, even if the vertical distance between the upper landing entrance / exit 6 and the lower landing entrance / exit 6 changes, the entrance / exit protection device 10 can be easily attached by changing only the vertical length of the lower protective plate 19, without changing the relative position between the entrance / exit protection device 10 and the upper landing entrance / exit 6 in the vertical direction.
[0091] Furthermore, if the vertical distance between the upper landing entrance / exit 6 and the lower landing entrance / exit 6 changes and the upper end through-hole 15c of the protective plate 19 does not face the screw hole 20a, the position of each support 20 relative to the protective plate 19 can be adjusted in the vertical direction so that the upper end through-hole 15c of the protective plate 19 faces the screw hole 20a.
[0092] Furthermore, by providing a plurality of screw holes 21a aligned in the vertical direction in each support 21, if the upper end through-hole 15c of the protective plate 19 does not face the screw hole 20a when the vertical distance between the upper landing entrance / exit 6 and the lower landing entrance / exit 6 changes, the position of the protective plate 19 relative to the supports 20 and 21 can be adjusted in the vertical direction to make the upper end through-hole 15c of the protective plate 19 face the screw hole 20a.
[0093] In the elevator entrance protection device in the first embodiment, protection member 11 extends from the lower end of toe protection plate 9c to the lower end of protection plate 19 and is larger than car entrance 3 in the width direction of the entrance.
[0094] Furthermore, in the elevator entrance protection device in the first embodiment, the entrance protection device 10 does not have to be symmetrical in the width direction of the entrance with respect to the center of the entrance.
[0095] Furthermore, in the elevator entrance protection device according to the first embodiment, the protection plate 15 has two pairs of upper end through-holes 15c and lower end through-holes 15d, but may have one or three or more pairs of upper end through-holes 15c and lower end through-holes 15d. In this case, the protection plate 15 is fixed to the support member 12 by passing a screw member 22 through each of the upper end through-holes 15c and each of the lower end through-holes 15d and screwing the screw member 22 into the support member 12.
[0096] In the elevator entrance protection device according to the first embodiment, the upper end through-hole 15c and the lower end through-hole 15d may be provided at the center of the protection plate 15 in the width direction of the entrance.
[0097] In the elevator entrance protection device according to the first embodiment, the relative positional relationship among the multiple protection plates 15 in the depth direction of the entrance may be different from the above-described positional relationship.
[0098] In the elevator entrance protection device according to the first embodiment, each support 20 may be divided into a plurality of support members in the vertical direction.
[0099] Furthermore, in the elevator entrance protection device according to the first embodiment, support member 12 may be fixed to a support member such as a beam or a pillar fixed inside hoistway 1, instead of being fixed to wall 1a.
[0100] Furthermore, by extending the landing door opening and closing device cover 8b of the lower landing 5 upward, the gap in the vertical direction between the lower end of the protection member 11 and the landing door opening and closing device cover 8b may be eliminated or reduced.
[0101] Next, an elevator entrance protection device according to a first modified example of the first embodiment will be described with reference to the drawings. Fig. 10 is a longitudinal cross-sectional view of a hoistway according to the first modified example of the first embodiment. Fig. 11 is a front view of the elevator entrance protection device according to the first modified example of the first embodiment. Fig. 11 is a view taken along the arrow EE in Fig. 10. Fig. 12 is a drawing showing the shape of the protection plate according to the first modified example of the first embodiment. Fig. 12 is a drawing obtained by third angle projection. In the description of the elevator entrance protection device according to the first modified example of the first embodiment, the description of the same configuration as that of the elevator entrance protection device according to the first embodiment will be omitted as appropriate hereinafter, and reference numerals in the drawings will be omitted as appropriate.
[0102] In the drawing, 30 is an entrance / exit protection device and 31 is a protection plate.
[0103] The elevator entrance protection device in the first modified example of the first embodiment is the elevator entrance protection device in the above-described first embodiment, with protection plate 19 changed to protection plate 31. Except for this change, the elevator entrance protection device in the first modified example of the first embodiment is the same as the elevator entrance protection device in the first embodiment.
[0104] The protective plate 31 is the protective plate 15 located at the bottom of the protective member 11. Therefore, the protective plate 31 is a bottom end protective plate.
[0105] The protective plate 15, which is the protective plate 31, has two fixed portions 15a, a flexible portion 15b, two pairs of upper end through-portions 15c and lower end through-portions 15d, and a plurality of intermediate through-portions 15f.
[0106] On one and the other widthwise sides of the entrance in the protective plate 15, which is the protective plate 31, the multiple intermediate through portions 15f are located between the upper end through portion 15c and the lower end through portion 15d. The multiple intermediate through portions 15f are located at the two fixing portions 15a of the protective plate 15, which is the protective plate 31. The multiple intermediate through portions 15f penetrate the protective plate 15, which is the protective plate 31, in the depth direction of the entrance. On one and the other widthwise sides of the entrance in the protective plate 15, which is the protective plate 31, the upper end through portion 15c, the lower end through portion 15d, and the multiple intermediate through portions 15f are lined up in a row in the vertical direction.
[0107] On one and the other widthwise sides of the entrance in the protective member 11, the male threads of the screw members 22 are passed through the lower end through-portion 15d of the protective plate 18 and the upper end through-portion 15c of the protective plate 31, and are screwed into the screw holes 20a. On one and the other widthwise sides of the entrance in the protective member 11, the male threads of the screw members 22 are passed through the lower end through-portion 15d of the protective plate 31, and are screwed into the screw holes 21a.
[0108] On one and the other widthwise sides of the entrance in the protective member 11, instead of the male threaded portions of the screw members 22 being passed through the lower end through-portion 15d of the protective plate 18 and the upper end through-portion 15c of the protective plate 31, the male threaded portions of the screw members 22 are passed through the lower end through-portion 15d of the protective plate 18 and the intermediate through-portion 15f of the protective plate 31 and screwed into the screw holes 20a, thereby fastening the protective plate 18 and the protective plate 31 to the support 20. In this case, the fixed portions 15a and flexible portions 15b of the protective plate 18 and the fixed portions 15a and flexible portions 15b of the protective plate 31 can overlap with each other in the depthwise direction of the entrance.
[0109] In the elevator entrance / exit protection device in the first variant of embodiment 1, the lower protective plate 31 has an intermediate through-hole 15f, which is located between the upper end through-hole 15c and the lower end through-hole 15d, and the upper screw member of the lower protective plate 31 is passed through the lower end through-hole 15d of the upper protective plate 18 and the intermediate through-hole 15f of the lower protective plate 31 and screwed into the screw hole 20a of the support 20, thereby tightening the upper protective plate 18 and the lower protective plate 31 to the support 20, and at the same time, the lower screw member of the lower protective plate 31 is passed through the lower end through-hole 15d of the lower protective plate 31 and screwed into the screw hole 21a of the support 21, thereby tightening the lower protective plate 31 to the support 21.
[0110] As a result, the vertical length of the entrance / exit protection device 10 can be changed, so even if the vertical distance between the upper landing entrance / exit 6 and the lower landing entrance / exit 6 changes, the entrance / exit protection device 10 can be easily attached.
[0111] Furthermore, since the upper protective plates can be made identical for two types of entrance protection devices 10 having different lengths in the up-down direction, the number of types of upper protective plates can be reduced.
[0112] Furthermore, when the vertical distance between the upper landing entrance / exit 6 and the lower landing entrance / exit 6 changes and the intermediate through-hole 15f of the protective plate 31 does not face the screw hole 20a, the position of each support 20 relative to the protective plate 31 can be adjusted in the vertical direction so that the intermediate through-hole 15f of the protective plate 31 faces the screw hole 20a.
[0113] Furthermore, by providing a plurality of screw holes 21a aligned in the vertical direction in each support 21, if the vertical distance between the upper landing entrance / exit 6 and the lower landing entrance / exit 6 changes and the intermediate through portion 15f of the protective plate 31 does not face the screw hole 20a, it is possible to make the intermediate through portion 15f of the protective plate 31 face the screw hole 20a by adjusting the position of the protective plate 31 in the vertical direction relative to each of the supports 20 and 21.
[0114] Next, an elevator entrance protection device according to a second modified example of the first embodiment will be described with reference to the drawings. Fig. 13 is a longitudinal cross-sectional view of a hoistway according to the second modified example of the first embodiment. Fig. 14 is a front view of the elevator entrance protection device according to the second modified example of the first embodiment. Fig. 14 is a view taken along the arrow FF in Fig. 13. Fig. 15 is a drawing showing the shape of the protection plate according to the second modified example of the first embodiment. Fig. 15 is a drawing using the third angle projection method. In the description of the elevator entrance protection device according to the second modified example of the first embodiment, the description of the same configuration as that of the elevator entrance protection device according to the first embodiment will be omitted as appropriate, and reference numerals in the drawings will be omitted as appropriate.
[0115] In the drawing, 40 is an entrance / exit protection device and 41 is a protection plate.
[0116] The elevator entrance protection device in the second modified example of the first embodiment is the elevator entrance protection device in the first embodiment described above, except that protection plate 19 is changed to protection plate 41. Except for this change, the elevator entrance protection device in the second modified example of the first embodiment is the same as the elevator entrance protection device in the first embodiment.
[0117] The protective plate 41 is the protective plate 15 located at the bottom of the protective member 11. Therefore, the protective plate 41 is a bottom end protective plate.
[0118] The protective plate 15, which is the protective plate 41, has two fixed portions 15a, a flexible portion 15b, two pairs of upper end through-portions 15c and lower end through-portions 15d, a plurality of intermediate through-portions 15f, and a plurality of screw members 15k.
[0119] On one and the other widthwise sides of the entrance in the protective plate 15, which is the protective plate 41, the multiple intermediate through portions 15f are located between the upper end through portion 15c and the lower end through portion 15d. The multiple intermediate through portions 15f are located at the two fixing portions 15a of the protective plate 15, which is the protective plate 41. The multiple intermediate through portions 15f penetrate the protective plate 15, which is the protective plate 41, in the depth direction of the entrance. On one and the other widthwise sides of the entrance in the protective plate 15, which is the protective plate 41, the upper end through portion 15c, the lower end through portion 15d, and the multiple intermediate through portions 15f are lined up in a row in the vertical direction.
[0120] The protective plate 15, which is the protective plate 41, is divided into an upper protective plate 15g and a lower protective plate 15h. The protective plate 15, which is the protective plate 41, has an upper protective plate 15g and a lower protective plate 15h. The upper protective plate 15g forms the upper part of the protective plate 15, which is the protective plate 41. The lower protective plate 15h forms the lower part of the protective plate 15, which is the protective plate 41. The upper protective plate 15g has two fixed portions 15a, a flexible portion 15b, two upper end through-portions 15c, and multiple intermediate through-portions 15f. The lower protective plate 15h has two fixed portions 15a, a flexible portion 15b, two lower end through-portions 15d, and multiple intermediate through-portions 15f.
[0121] The fixed portions 15a and flexible portions 15b of the upper protective plate 15g and the fixed portions 15a and flexible portions 15b of the lower protective plate 15h overlap in the depth direction of the entrance. On one and the other widthwise sides of the entrance in the protective plate 15 that is the protective plate 41, the intermediate through portions 15f of the upper protective plate 15g and the intermediate through portions 15f of the lower protective plate 15h overlap in the depth direction of the entrance.
[0122] Screw members 15k are positioned on one and the other widthwise sides of the opening in the protective plate 15, which is the protective plate 41. On one and the other widthwise sides of the opening in the protective plate 15, which is the protective plate 41, the male threads of the screw members 15k are passed through the intermediate through-holes 15f of the upper protective plate 15g and the intermediate through-holes 15f of the lower protective plate 15h, and are screwed into the female threads of the screw members 15k. Each screw member 15k sandwiches the upper protective plate 15g and the lower protective plate 15h between its head and its female thread. Each screw member 15k fastens the upper protective plate 15g and the lower protective plate 15h together. Each screw member 15k is, for example, a bolt, a nut, a flat washer, or a spring washer. In this case, the male threaded portion is the shank of the bolt, the outer surface of which has male threads, the head is the head of the bolt, and the female threaded portion is the cylindrical portion of the nut, the inner surface of which has female threads.
[0123] In the protective plate 15 that is the protective plate 41, the vertical length of the protective plate 15 that is the protective plate 41 can be changed by changing the relative positions of the upper protective plate 15g and the lower protective plate 15h in the vertical direction.
[0124] In the elevator entrance protection device in the second variant of embodiment 1, the side protection plate 41 has an upper protection plate 15g, a lower protection plate 15h, multiple intermediate penetration portions 15f and a screw member 15k, the multiple intermediate penetration portions 15f are located between the upper end penetration portion 15c and the lower end penetration portion 15d, the upper protection plate 15g forms the upper part of the lower protection plate 41 and has the upper end penetration portion 15c and multiple intermediate penetration portions 15f, the lower protection plate 15h forms the lower part of the lower protection plate 41 and has the lower end penetration portion 15d and multiple intermediate penetration portions 15f, the upper protection plate 15g and the lower protection plate 15h are stacked in the depth direction of the car entrance 3, and the screw member 15k is passed through the intermediate penetration portion 15f of the upper protection plate 15g and the intermediate penetration portion 15f of the lower protection plate 15h and fastens the upper protection plate 15g and the lower protection plate 15h together.
[0125] This allows the vertical length of the protection plate 41 to change, so even if the vertical distance between the upper landing entrance 6 and the lower landing entrance 6 changes, the entrance protection device 10 can be easily attached.
[0126] Furthermore, since the upper protective plates can be made identical for two types of entrance protection devices 10 having different lengths in the up-down direction, the number of types of upper protective plates can be reduced.
[0127] Next, an elevator entrance protection device according to a second embodiment will be described with reference to the drawings. FIG. 16 is a longitudinal cross-sectional view of a hoistway according to the second embodiment. FIG. 17 is a front view of the elevator entrance protection device according to the second embodiment.

FIG. 19 is a drawing showing the shape of the protection plate according to the second embodiment. FIG. 19 is a drawing taken along the third angle projection. FIG. 20 is a drawing showing the shape of the support according to the second embodiment. FIG. 20 is a drawing taken along the third angle projection. FIG. 21 is a detailed view of part H in FIG. 17. FIG. 21(a) is a plan view, FIG. 21(b) is a front view, and FIG. 21(c) is a right side view. FIG. 22 is a detailed view of part K in FIG. 17. Fig. 22(a) is a plan view, Fig. 22(b) is a front view, and Fig. 22(c) is a right side view. Fig. 23 is a detailed view of part M in Fig. 17. Fig. 23(a) is a plan view, Fig. 23(b) is a front view, and Fig. 23(c) is a right side view. In the description of the elevator entrance protection device in embodiment 2, the same configuration as the elevator entrance protection device in embodiment 1 will not be described below as appropriate, and reference numerals in the drawings will be omitted as appropriate.
[0128] In the drawing, 50 is an entrance / exit protection device, 51 is a protection plate, and 52 is a support.
[0129] The elevator entrance protection device in the second embodiment is the same as the elevator entrance protection device in the first embodiment except that the protection plate 19 and the two supports 20 are replaced with a protection plate 51 and two supports 52. Apart from this change, the elevator entrance protection device in the second embodiment is the same as the elevator entrance protection device in the first embodiment.
[0130] The protective plate 51 is the protective plate 15 located at the bottom of the protective member 11. Therefore, the protective plate 51 is a bottom end protective plate.
[0131] The protective plate 15, which is the protective plate 51, has two fixed portions 15a, a flexible portion 15b, and two pairs of upper end penetrating portions 15c and lower end penetrating portions 15d.
[0132] The width of the opening in the protective plate 15, which is the protective plate 51, is longer than the width of the opening in the protective plate 15, which are the protective plates 16, 17, and 18.
[0133] Each support 52 has a protection piece 52a, a plurality of screw holes 52b and 52c, and a plurality of elongated holes 52d.
[0134] Each protective piece 52a extends vertically and in the width direction of the entrance. Each protective piece 52a is located on the side of each support 52 opposite the wall 1a. The gap between each protective piece 52a and the car entrance 3 is smaller than the gap between the wall 1a and the car entrance 3. Each protective piece 52a faces the wall 1a side of the protective plates 16, 17, 18, and 51. Each protective piece 52a is aligned with the protective plates 16, 17, 18, and 51. The protective piece 52a of one support 52 is aligned with one fixing portion 15a of the protective plates 16, 17, 18, and 51. The protective piece 52a of the other support 52 is aligned with the other fixing portion 15a of the protective plates 16, 17, 18, and 51. Each protective piece 52a supports the protective plates 16, 17, 18, and 51. Each protective piece 52a has multiple screw holes 52b and 52c.
[0135] The multiple screw holes 52b of the two supports 52 correspond to the multiple screw holes 20a of the two supports 20. The multiple screw holes 52c of the two supports 52 correspond to the multiple screw holes 20a of the two supports 20. The multiple screw holes 52b and 52c of each support 52 are included in the multiple screw holes 12a.
[0136] In each protective piece 52a, the multiple screw holes 52c are located further outward in the width direction of the entrance than the multiple screw holes 52b. In each protective piece 52a, each screw hole 52b and each screw hole 52c form a pair. In each pair of the multiple screw holes 52b and 52c in each protective piece 52a, the screw holes 52b and the screw holes 52c are aligned in the width direction of the entrance. In each protective piece 52a, the screw holes 52b and the screw holes 52c are aligned at equal intervals in the same direction in the width direction of the entrance.
[0137] The plurality of elongated holes 52 d of the two supports 52 are elongated holes corresponding to the plurality of elongated holes 20 b of the two supports 20 .
[0138] The protective plates 16, 17, 18 and 51 of the protective member 11 and the supports 21 and 52 of the support member 12 can be attached in a desired one of a first attachment state and a second attachment state.
[0139] In the first mounting state, each screw member 22 is mounted as follows.
[0140] On one and the other widthwise sides of the opening in the protective member 11, the male threaded portions of the screw members 22 are passed through the upper end through-portions 15c of the protective plate 16 and are screwed into the screw holes 52b. On one and the other widthwise sides of the opening in the protective member 11, the male threaded portions of the screw members 22 are passed through the lower end through-portions 15d of the protective plate 16 and the upper end through-portions 15c of the protective plate 17 and are screwed into the screw holes 52b. On one and the other widthwise sides of the opening in the protective member 11, the male threaded portions of the screw members 22 are passed through the lower end through-portions 15d of the protective plate 17 and the upper end through-portions 15c of the protective plate 18 and are screwed into the screw holes 52b. On one and the other widthwise sides of the entrance in the protective member 11, the male threads of the screw members 22 are passed through the lower end through-portion 15d of the protective plate 18 and the upper end through-portion 15c of the protective plate 51, and are screwed into the screw holes 52b. On one and the other widthwise sides of the entrance in the protective member 11, the male threads of the screw members 22 are passed through the lower end through-portion 15d of the protective plate 51, and are screwed into the screw holes 21a.
[0141] Here, the upper screw hole of the protection plate 15 in the first attachment state is referred to as the first upper screw hole of the protection plate 15. Also, the lower screw hole of the protection plate 15 in the first attachment state is referred to as the first lower screw hole of the protection plate 15.
[0142] In the first mounting state, the first upper screw holes face the respective upper end through-portions 15c, and the first lower screw holes face the respective lower end through-portions 15d.
[0143] In the first attachment state, the upper screw member is passed through the upper end through-portion 15c and screwed into the first upper screw hole, thereby fastening the protective plate 15 and the support member 12. In the first attachment state, the lower screw member is passed through the lower end through-portion 15d and screwed into the first lower screw hole, thereby fastening the protective plate 15 and the support member 12.
[0144] In the first installation state, on one side and the other side of the width of the entrance in the upper protective plate 15 and the lower protective plate 15 which are adjacent to each other in the vertical direction, one of the first lower screw holes in the upper protective plate 15 and the first upper screw hole in the lower protective plate 15 doubles as the other.
[0145] In the first installation state, on one side and the other side of the width of the entrance on the upper protective plate 15 and the lower protective plate 15 which are adjacent to each other in the vertical direction, one of the lower screw member of the upper protective plate 15 and the upper screw member of the lower protective plate 15 doubles as the other.
[0146] In the second mounting state, each screw member 22 is mounted as follows.
[0147] On one and the other widthwise sides of the opening in the protective member 11, the male threaded portions of the screw members 22 are passed through the upper end through-portions 15c of the protective plate 16 and are screwed into the screw holes 52c. On one and the other widthwise sides of the opening in the protective member 11, the male threaded portions of the screw members 22 are passed through the lower end through-portions 15d of the protective plate 16 and the upper end through-portions 15c of the protective plate 17 and are screwed into the screw holes 52c. On one and the other widthwise sides of the opening in the protective member 11, the male threaded portions of the screw members 22 are passed through the lower end through-portions 15d of the protective plate 17 and the upper end through-portions 15c of the protective plate 18 and are screwed into the screw holes 52c. On one and the other widthwise sides of the entrance in the protective member 11, the male threads of the screw members 22 are passed through the lower end through-portion 15d of the protective plate 18 and the upper end through-portion 15c of the protective plate 51, and are screwed into the screw holes 52c. On one and the other widthwise sides of the entrance in the protective member 11, the male threads of the screw members 22 are passed through the lower end through-portion 15d of the protective plate 51, and are screwed into the screw holes 21a.
[0148] Here, in the second attachment state, the upper screw hole of the protection plate 15 is referred to as the second upper screw hole of the protection plate 15. Also, in the second attachment state, the lower screw hole of the protection plate 15 is referred to as the second lower screw hole of the protection plate 15.
[0149] In the second mounting state, the second upper screw holes face the upper end through-portions 15c, and the second lower screw holes face the lower end through-portions 15d.
[0150] In the second attachment state, the upper screw member is passed through the upper end through-portion 15c and screwed into the second upper screw hole, thereby fastening the protective plate 15 and the support member 12. In the second attachment state, the lower screw member is passed through the lower end through-portion 15d and screwed into the second lower screw hole, thereby fastening the protective plate 15 and the support member 12.
[0151] In the second installation state, on one side and the other side of the width of the entrance in the upper protective plate 15 and the lower protective plate 15 which are adjacent to each other in the vertical direction, one of the second lower screw holes of the upper protective plate 15 and the second upper screw hole of the lower protective plate 15 doubles as the other.
[0152] In the second installation state, on one side and the other side of the width of the entrance in the upper protective plate 15 and the lower protective plate 15, which are adjacent to each other in the vertical direction, one of the lower screw member of the upper protective plate 15 and the upper screw member of the lower protective plate 15 also serves as the other.
[0153] The first lower screw hole and the second lower screw hole include screw holes 20a and 21a, respectively, but the first lower screw hole, which is screw hole 21a, and the second lower screw hole, which is screw hole 21a, are the same screw hole 21a.
[0154] Each support 52 in the first installation state is positioned outward in the width direction of the entranceway than each support 52 in the second installation state. On one and the other sides of the width direction of the entranceway of the protective member 11 and support 52 in the first installation state, each protective piece 52a protrudes outward from the protective plates 16, 17, and 18 in the width direction of the entranceway.
[0155] The widthwise length of the opening in the entire protective plates 16, 17, and 18 of the protective member 11 and each protective piece 52a of the support member 12 in the first attachment state is longer than the widthwise length of the opening in the entire protective plates 16, 17, and 18 of the protective member 11 and each protective piece 52a of the support member 12 in the second attachment state. The widthwise length of the opening in the entire protective plates 16, 17, and 18 of the protective member 11 and each protective piece 52a of the support member 12 in the first attachment state is not the same as the widthwise length of the opening in the entire protective plates 16, 17, and 18 of the protective member 11 and each protective piece 52a of the support member 12 in the second attachment state, and is not shorter than the widthwise length of the opening in the entire protective plates 16, 17, and 18 of the protective member 11 and each protective piece 52a of the support member 12 in the second attachment state.
[0156] The first and second attachment states are different in the width direction of the entrance of the entire protective member 11 and each protective portion 52a.
