[0007] Embodiments of the present invention will be described below with reference to the drawings. These embodiments are not limiting to the present invention. In the drawings referenced in the embodiments, the same or similar reference numerals are used for identical parts or parts having similar functions, and repeated descriptions thereof are omitted.

[0008] (First embodiment) As shown in Figure 1, the elevator car entrance / exit device 10 according to the first embodiment is provided on the side of the car entrance / exit 1a in the elevator car 1. As shown in Figure 1, a ceiling 2 is provided above the car 1. A car floor 3 is provided below the car 1. Multiple wall panels 4 that form the side walls of the car 1 are provided on both the left and right sides and the rear of the car 1. Multiple baseboards 5 are provided between the lower ends of the wall panels 4 and the car floor 3.

[0009] Hereinafter, the direction along the width of the elevator car entrance 1a will be defined as the X direction. The direction perpendicular to the elevator car floor 3 will be defined as the Y direction. The direction perpendicular to both the X and Y directions will be defined as the Z direction.

[0010] An entrance / exit 1a is provided at the front of the elevator car 1. The entrance / exit 1a is opened and closed by a pair of doors 6. The entrance / exit device 10 includes a pair of hollow entrance / exit pillars 7 erected on both the left and right sides of the entrance / exit 1a. An upper plate 8 is provided above the entrance / exit 1a. A pair of side wall panels 9 are provided between the entrance / exit pillars 7 and the side wall panels 4 of the elevator car 1.

[0011] The elevator car entrance / exit device 10 further includes a mounting bracket 11 attached between the entrance / exit column 7 and the elevator car floor 3. Because the entrance / exit column 7 is connected to the elevator car floor 3 via the mounting bracket 11, when a trolley 20 collides with the vicinity of the lower end of the entrance / exit column 7 from the direction moving from the inside to the outside of the elevator car 1, as shown by arrow A in Figure 2, displacement due to movement and rotation of the entrance / exit column 7 can be suppressed. The mounting bracket 11 may further suppress deformation of the entrance / exit column 7 when a trolley 20 collides with the vicinity of the lower end of the entrance / exit column 7.

[0012] As shown in Figures 3 and 4, which are enlarged views of the inside of frame F in Figure 2, the entrance column 7 has an opposing portion 7a, an outer end portion 7b, an inner end portion 7c, a folded portion 7d, and a metal fitting 7e.

[0013] The opposing portion 7a of the entrance / exit column 7 has a flat plate shape along the YZ plane. The opposing portion 7a faces the car entrance / exit 1a and opposes another entrance / exit column 7 disposed on the opposite side in the opening / closing direction of the door 6.

[0014] The outer end portion 7b has a flat plate shape along the XY plane. More specifically, the outer end portion 7b has a shape formed by bending the end portion of the opposing portion 7a on the outer side (i.e., the landing side) of the car compartment 1 at a right angle toward the outer side (i.e., the -X direction) in the opening / closing direction of the door 6. In other words, the outer end portion 7b extends from the Z-direction end portion of the opposing portion 7a in the -X direction. The outer end portion 7b faces the door 6 in the front-rear direction along the Z direction.

[0015] The inner end portion 7c has a flat plate shape along the XY plane. More specifically, the inner end portion 7c has a shape formed by bending the end portion of the opposing portion 7a on the inner side of the car compartment 1 at a right angle toward the outer side in the opening / closing direction of the door 6. In other words, the inner end portion 7c extends from the -Z-direction end portion of the opposing portion 7a in the -X direction. The inner end portion 7c faces the interior of the car compartment 1.

[0016] The folded-back portion 7d has a flat plate shape along the YZ plane. More specifically, the folded-back portion 7d has a shape formed by bending the end portion of the inner end portion 7c on the side opposite to the opposing portion 7a at a right angle toward the outer end portion 7b side. In other words, the folded-back portion 7d extends from the -X-direction end portion of the inner end portion 7c in the Z direction. The folded-back portion 7d faces the opposing portion 7a in the opening / closing direction of the door 6. The width-direction one end portion of the sleeve wall panel 9 abuts on the folded-back portion 7d.

[0017] The fitting 7e is located on the sleeve wall panel 9 side with respect to the opposing portion 7a. The fitting 7e fastens both the car floor 3 and the mounting fitting 11 together. The fitting 7e has a first floor fixing portion 7f for fastening the mounting fitting 11 and the car floor 3. The first floor fixing portion 7f has a flat plate shape along the car floor 3.

[0018] The mounting bracket 11 has an impact receiving portion 13b and a second floor fixing portion 12a. The mounting bracket 11 suppresses the movement of the entrance column 7 when an external force acts on the entrance column 7 in a direction from the inside to the outside of the car 1 (i.e., the Z direction). The impact receiving portion 13b contacts the lower end of the entrance column 7 from a direction from the outside to the inside of the car 1 (i.e., the -Z direction). The impact receiving portion 13b absorbs the impact from the entrance column 7 when an external force acts on the entrance column 7 in a direction from the inside to the outside of the car 1. The second floor fixing portion 12a is fixed on the car floor 3. The second floor fixing portion 12a has a flat plate shape along the car floor 3.

[0019] More specifically, the mounting bracket 11 includes a first mounting piece 12, a second mounting piece 13, and at least one third mounting piece 14.

[0020] The first mounting piece 12 has the second bed fixing portion 12a and the first mounting piece fixing portion 12b described above.

[0021] The first mounting piece fixing portion 12b has a flat plate shape along the XY plane. More specifically, the first mounting piece fixing portion 12b has a shape that rises vertically upward (i.e., in the Y direction) from the end of the second floor fixing portion 12a on the outside side of the elevator car 1. The first mounting piece fixing portion 12b faces the inner surface of the entrance column 7 (i.e., the outer end portion 7b). The second mounting piece 13 and the third mounting piece 14 are fixed to the first mounting piece fixing portion 12b.

[0022] The second floor fixing part 12a is horizontally fastened to the cage floor 3 by a single bolt 15. The second floor fixing part 12a is provided with a hole 12c through which the bolt 15 passes. The bolt 15 is screwed into a threaded hole provided in the cage floor 3. The bolt 15 is a cap bolt, or socket head cap bolt. Because the bolt 15 is a cap bolt, it can be properly fastened using a wrench even when the range of rotation of the tool is restricted. The first mounting piece fixing part 12b is provided with two threaded holes 12d through which the bolt 16 passes.

[0023] The second mounting piece 13 has a second mounting piece fixing portion 13a and the impact receiving portion 13b described above.

[0024] The second mounting piece fixing portion 13a is fixed to the first mounting piece fixing portion 12b. The second mounting piece fixing portion 13a has a flat plate shape along the XY plane. The second mounting piece fixing portion 13a is fastened by two bolts 16 that are spaced apart along the width direction (i.e., the X direction) of the car entrance 1a. More specifically, the second mounting piece fixing portion 13a is provided with a plurality of holes 13c through which the bolts 16 pass. The second mounting piece fixing portion 13a is superimposed on the inner surface of the first mounting piece fixing portion 12b and fixed by the bolts 16.

[0025] The impact receiving portion 13b has a flat plate shape along the YZ plane. More specifically, the impact receiving portion 13b has a shape that extends perpendicularly toward the inside of the car 1 (i.e., in the -Z direction) from the end of the inner second mounting piece fixing portion 13a in the opening and closing direction of the door 6 (i.e., the end of the second mounting piece fixing portion 13a in the X direction). The impact receiving portion 13b faces the inner surface of the entrance column 7 (i.e., the inner end portion 7c).

[0026] The third mounting piece 14 can be inserted into and removed from above between the first mounting piece fixing part 12b and the second mounting piece fixing part 13a. The third mounting piece 14 allows the position of the mounting bracket 11 to be adjusted in the direction of moving toward or away from the lower end of the entrance column 7, depending on the number of third mounting pieces 14 inserted. As shown in Figure 4, the third mounting piece 14 has two notches 14a that do not obstruct the passage of the bolts 16. The third mounting piece 14 is interposed between the first mounting piece fixing part 12b and the second mounting piece fixing part 13a while avoiding interference with the bolts 16 via the notches 14a. The third mounting piece 14 is fixed between the first mounting piece fixing part 12b and the second mounting piece fixing part 13a using the fastening force of the two bolts 16.

[0027] When installing the car entrance device 10 according to the first embodiment configured as described above, first, the maintenance worker removes the side wall panel 9 to expose the inside of the entrance column 7. Next, the bolts and other fasteners that secure the entrance column 7 to the car floor 3 are removed. Then, the mounting bracket 11 is placed on the first floor fixing part 7f so that the second floor fixing part 12a overlaps the first floor fixing part 7f. Next, the impact receiving part 13b of the second mounting piece 13 is placed against the inner end 7c of the entrance column 7. Then, the mounting bracket 11 is fixed with bolts 15. At this time, at least one third mounting piece 14 is inserted from above between the first mounting piece fixing part 12b and the second mounting piece fixing part 13a so that the impact receiving part 13b contacts the inner end 7c. If too many third mounting pieces 14 are to be inserted, the excess third mounting pieces 14 that could not be inserted are removed.

[0028] According to the first embodiment, the mounting bracket 11 is fixed to the inner surface of the entrance column 7 and is not exposed to the outside of the entrance column 7. Therefore, it is not necessary to reduce the floor area of ​​the elevator car 1 or to degrade its aesthetic appeal in order to install the mounting bracket 11.

[0029] Furthermore, conventionally, if the entrance / exit post 7 shifted from its predetermined position, maintenance personnel had to make fine adjustments each time. In contrast, according to the first embodiment, by employing the mounting bracket 11, the work of making fine adjustments to the entrance / exit post 7 to its predetermined position becomes unnecessary, thus reducing the labor and cost required for maintenance.

[0030] Furthermore, according to the first embodiment, the mounting bracket 11 having the impact receiving portion 13b is fixed to the car floor 3 via the second floor fixing portion 12a. Therefore, as shown in Figure 5, when a trolley 20 moving in the direction of arrow A from inside the car 1 to outside the car 1 collides with the entrance pillar 7, and an impact (i.e., external force) acts on the entrance pillar 7 from inside the car 1, the impact receiving portion 13b can mitigate the impact from inside the car 1. By mitigating the impact from inside the car 1, the movement of the entrance pillar 7 can be suppressed. Thus, the entrance pillar 7 can be efficiently reinforced with a simple configuration, and contact between the entrance pillar 7 and the car door 6 due to the movement of the entrance pillar 7 can be suppressed. In addition, fine position adjustments can be made by adding or removing multiple third mounting pieces 14 so that the impact receiving portion 13b can contact the inner surface of the entrance pillar 7 (i.e., the inner end portion 7c) as much as possible. Furthermore, depending on the positional relationship between the lower end of the entrance column 7 and the mounting bracket 11, it may be possible to bring the impact receiving portion 13b into contact with the inner surface of the entrance column 7 without requiring the third mounting piece 14. In this case, the third mounting piece 14 can be omitted. The possibility of omitting the third mounting piece 14 is also true in subsequent embodiments.

[0031] (Second embodiment) Next, a second embodiment for suppressing the rotation of the mounting bracket 11 will be described, focusing on the differences from the embodiment described above. As shown in Figure 6, in the second embodiment, the car floor 3 is provided with a hole 3a through which the wiring of a display device installed in the car compartment 1 passes. The car floor 3 is also provided with a rubber bush 23 that is positioned along the side wall of the hole 3a and protects the hole 3a. The rubber bush 23 is an example of a cushioning member.

[0032] In the second embodiment, the first mounting piece 12 further includes a rotation-restricting portion 12e. The rotation-restricting portion 12e is inserted into the hole 3a so as to contact the rubber bush 23 and suppresses the rotation of the mounting bracket 11. The rotation-restricting portion 12e extends vertically downward (i.e., in the -Y direction) from the outer end of the second floor fixing portion 12a in the opening and closing direction of the door 6 (i.e., the -X end of the second floor fixing portion 12a). The lower end of the rotation-restricting portion 12e is chamfered. The edges of the rotation-restricting portion 12e are wrapped with, for example, vinyl tape to prevent them from becoming sharp.

[0033] The procedure for installing the car entrance / exit device 10 according to the second embodiment is basically the same as that of the first embodiment. In the second embodiment, the mounting bracket 11 is installed by inserting the rotation suppression part 12e into the rubber bush 23.

[0034] According to the second embodiment, when the trolley 20 collides with the entrance / exit column 7 and an external force in the Z direction is applied to the entrance / exit column 7, the impact receiving portion 13b can mitigate the impact of the external force applied to the entrance / exit column 7, and the rotation suppression portion 12e inserted into the rubber bush 23 can suppress the rotation of the mounting bracket 11 clockwise around the bolt 15. As a result, not only the movement but also the rotational movement of the entrance / exit column 7 can be suppressed, so the entrance / exit column 7 can be reinforced more appropriately.

[0035] (Third embodiment) Next, we will describe a third embodiment in which the impact receiving portion 13b is extended upward, focusing on the differences from the embodiments described above. As shown in Figure 7, the impact receiving portion 13b in the third embodiment has an extension portion 131.

[0036] The extension portion 131 extends upward (i.e., in the Y direction) above the portion of the impact receiving portion 13b other than the extension portion 131. The extension portion 131 may extend the upper end of the impact receiving portion 13b by approximately 30 mm above the impact receiving portion 13b of the first embodiment.

[0037] According to the third embodiment, the extension portion 131 extends the upper end of the impact receiving portion 13b upward, thereby expanding the range over which the impact receiving portion 13b can absorb impact compared to the first embodiment. As a result, compared to the impact receiving portion 13b of the first embodiment, the distance from the cage floor 3 to the point of impact that can be absorbed when the trolley 20 collides with the entrance pillar 7 can be increased. In other words, even when a trolley with a high height from the cage floor 3 to the platform collides with the entrance pillar 7, the extension portion 131 can mitigate the impact and suppress the movement of the entrance pillar 7.

[0038] (Fourth embodiment) Next, we will describe a fourth embodiment in which the impact receiving portion 13b is movable in the vertical direction, focusing on the differences from the embodiments described above. As shown in Figures 8 and 9, in the fourth embodiment, the mounting bracket 11 further has a fourth mounting piece 28.

[0039] The second mounting piece 13 further has a third mounting piece fixing portion 13c to which the fourth mounting piece 28 is fixed. The third mounting piece fixing portion 13c has a flat plate shape along the XY plane. The third mounting piece fixing portion 13c is connected to the second mounting piece fixing portion 13a via a flat plate-shaped connecting portion 13d along the YZ plane.

[0040] The fourth mounting piece 28 has an impact receiving portion 13b and a fourth mounting piece fixing portion 28a.

[0041] The fourth mounting piece fixing portion 28a is positioned on top of the third mounting piece fixing portion 13c on the inside of the elevator car 1 (i.e., in the -Z direction). The fourth mounting piece fixing portion 28a is fixed to the third mounting piece fixing portion 13c by a bolt 29, a spring washer 30, and a nut 31 which constitute a fastening member. The impact receiving portion 13b extends in the -Z direction from the inner end of the fourth mounting piece fixing portion 28a in the opening and closing direction of the door 6 (i.e., the end of the fourth mounting piece fixing portion 28a in the X direction). The impact receiving portion 13b faces the inner surface of the entrance column 7 (i.e., the inner end portion 7c).

[0042] As shown in Figure 9, the fourth mounting piece fixing portion 28a is provided with an elongated hole 28c oriented in the vertical direction (i.e., the Y direction) through which the bolt 29 passes. The elongated hole 28c allows for changes in the fixing position of the fourth mounting piece fixing portion 28a in the vertical direction.

[0043] The procedure for installing the elevator car entrance device 10 according to the fourth embodiment is basically the same as that of the first embodiment. In the fourth embodiment, the mounting bracket 11 is fixed to the first floor fixing portion 7f of the entrance column 7 with a bolt 15. Next, the bolt 29 is loosened and the fourth mounting piece 28 is moved vertically to adjust the vertical position of the impact receiving portion 13b of the fourth mounting piece 28 that is pressed against the inner end portion 7c of the entrance column 7. Then, when the impact receiving portion 13b is in the desired position, the bolt 29 is tightened to fix the fourth mounting piece 28.

[0044] According to the fourth embodiment, by making the position of the impact receiving portion 13b adjustable in the vertical direction, the range over which the impact receiving portion 13b can absorb impact can be expanded to a higher position than in the first embodiment. As a result, the distance from the cage floor 3 to the point of impact that the trolley 20 receives when it collides with the entrance pillar 7 can be increased compared to the impact receiving portion 13b of the first embodiment. In other words, even when a trolley with a high height from the cage floor 3 to the platform collides with the entrance pillar 7, the impact receiving portion 13b of the fourth mounting piece 28 can mitigate the impact and suppress the movement of the entrance pillar 7. Furthermore, the impact receiving portion 13b can be adjusted to the optimal position according to the height of the trolley 20, thereby improving convenience.

[0045] (Fifth embodiment) Next, we will describe a fifth embodiment in which the impact receiving portion is composed of a fastening member 34, focusing on the differences from the embodiments described above. As shown in Figures 10 and 11, in the fifth embodiment, the mounting bracket 11 has a first mounting piece 12, a second mounting piece 13, and a bolt 34 (second fastening member) that constitutes the impact receiving portion.

[0046] In the fifth embodiment, the second mounting piece 13 further has a fastening portion 13e to which a bolt 34 is fastened. The fastening portion 13e is provided with one threaded hole 13f. The bolt 34 is fastened to the fastening portion 13e via the threaded hole 13f.

[0047] By rotating the bolt 34, the position of the bolt 34 can be adjusted in the direction of moving it toward or away from the lower end of the entrance column 7.

[0048] The procedure for installing the elevator car entrance device 10 according to the fifth embodiment is basically the same as that of the first embodiment. In the fifth embodiment, after attaching the mounting bracket 11 to the first floor fixing portion 7f of the entrance column 7 using bolts 15, the bolts 34 are rotated to tighten them so that they come into contact with the folded portion 7d of the entrance column 7, thereby fixing the position.

[0049] According to the fifth embodiment, the impact receiving portion can be further easily adjusted by using a bolt 34 instead of the third mounting piece 14 in the first embodiment.

[0050] (Sixth embodiment) Next, a sixth embodiment that utilizes a sill 42 to suppress impact on the entrance column 7 will be described, focusing on the differences from the embodiments described above. As shown in Figures 12 and 13, in the sixth embodiment, the second mounting piece 13 has a third floor fixing part 13g, which is an example of a second floor fixing part, and an impact receiving part 13b. The third floor fixing part 13g is fixed on the car floor 3 below the second floor fixing part 12a. The third floor fixing part 13g is in contact with a sill 42 installed below the car door 6 at its Z-direction end. The impact receiving part 13b extends upward from the -Z-direction end of the third floor fixing part 13g. The impact receiving part 13b is provided with two holes that allow for the fastening of two sets of bolts 40 and nuts 41.

[0051] The third mounting piece 14 can be inserted into and removed from above between the lower end of the entrance column 7 and the impact receiving portion 13b. The lower end of the third mounting piece 14 is provided with a vertical notch so as not to obstruct the passage of the bolt 40.

[0052] In the sixth embodiment, the maintenance worker removes the side wall panel 9 to expose the interior of the entrance column 7. The maintenance worker removes the fittings 7e and associated bolts and other accessories at the fastening portion between the entrance column 7 and the elevator car floor 3, and places the mounting bracket 11 on top of the third floor fixing portion 13g so that the second floor fixing portion 12a overlaps it. At this time, the Z-direction end of the third floor fixing portion 13g is brought into contact with the sill 42. Then, the impact receiving portion 13b is placed against the folded portion 7d of the entrance column 7, and the mounting bracket 11 is fixed with bolts 15. The third mounting piece 14 is inserted or removed from above the mounting bracket 11 so that the impact receiving portion 13b contacts the folded portion 7d.

[0053] According to the sixth embodiment, when the cage floor 3 and the sill 42 are not flush and there is a step, the end of the third floor fixing part 13g can be brought into contact with the sill 42, allowing the sill 42 to directly absorb the impact and movement of the entrance column 7. This makes it possible to more effectively suppress contact between the entrance column 7 and the cage door 6 due to the movement of the entrance column 7. In addition, fine position adjustments can be made by adding or removing multiple third mounting pieces 14 so that the mounting bracket 11 can contact the folded portion 7d as much as possible.

[0054] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These embodiments can be carried out in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims and their equivalents. [Explanation of symbols]
