DETAILED DESCRIPTION

[0031] For the following embodiments of the car and the elevator, refer to Figures 1 to 13 The same reference numerals are used for the common components in the drawings.

[0032] 1. The structure of the elevator

[0033] First, regarding the structure of the elevator of the embodiment example (hereinafter referred to as "this example"), refer to Figure 1 Provide explanation.

[0034] Figure 1 This is a schematic diagram showing the structure of the elevator of this example.

[0035] Figure 1 In the example shown, a so-called 2:1 roping (traction ratio) elevator 1 is shown. In addition, the elevator is not limited to a 2:1 roping elevator, and can also be applied to a 1:1 roping elevator.

[0036] like Figure 1 As shown, the elevator 1 includes a car 2 that moves up and down in a hoistway, a main rope 3, a traction machine 4, and a counterweight 5 suspended from the car 2 via the main rope 3. Hereinafter, the direction in which the car 2 and the counterweight 5 move up and down is referred to as the up and down direction.

[0037] People and cargo are carried in the car 2. A car side pulley 2a is provided at the upper part of the car 2 in the vertical direction. The main rope 3 is wound around the car side pulley 2a. A counterweight side pulley 5a is provided on the counterweight 5. The main rope 3 is wound around the counterweight side pulley 5a.

[0038] The hoisting machine 4 is installed at the uppermost position of the hoistway. In addition, the hoisting machine 4 has a sheave for winding the main rope 3. The hoisting machine 4 raises and lowers the car 2 and the counterweight 5 via the main rope 3 in a bucket-like manner.

[0039] One end of the main rope 3 is installed on the upper part of the hoistway. The main rope 3 extends from the upper part of the hoistway to the car side pulley 2a. The main rope 3 is wound from one end sequentially around the car side pulley 2a, the sheave of the traction machine 4, and the counterweight side pulley 5a.

[0040] In addition, the other end of the main rope 3 extending from the counterweight side pulley 5a to the upper part of the hoistway is installed in the upper part of the hoistway in the same manner as the one end. When the traction machine 4 is driven, the car 2 and the counterweight 5 are moved up and down in the hoistway.

[0041] 2. Example of car structure

[0042] Figure 2 It is a front view showing the interior of the car chamber of the car 2.

[0043] like Figure 1 and Figure 2 As shown, the car 2 includes a floor assembly 10 as the floor of the car room, side panels 11, a top panel 12, a door portion 13, and a frame 16 (see Figure 3 ). The bottom plate assembly 10 and the top plate 12 are arranged opposite to each other in the up-down direction. The side panels 11 are erected around the bottom plate assembly 10 and the top plate 12. In addition, the front side panel 14 arranged on the front of the car 2 among the side panels 11 surrounding the bottom plate assembly 10 is provided with an entrance and exit 14a. An operation panel and a display unit not shown in the figure are installed on the front side panel 14 in accordance with the design specifications of the customer. In addition, the size of the entrance and exit 14a can be changed in various ways in accordance with the design specifications of the customer. Therefore, the thickness and size of the front side panel 14 can be changed in various ways in accordance with the design specifications of the customer.

[0044] Furthermore, a door portion 13 is openably and closably provided at an entrance 14a provided at the front side plate 14. The floor assembly 10, the side plates 11, the ceiling 12, the front side plates 14 and the door portion 13 constitute a car room in the car 2 for carrying people and cargo.

[0045] Figure 3 and Figure 4 1 is a perspective view showing the bottom plate assembly 10 and the frame 16. Figure 5 It is a side view showing the bottom plate assembly 10 and the frame 16 .

[0046] like Figures 3 to 5 As shown, the floor assembly 10 is supported by a frame 16. The frame 16 has two vertical frames extending in the vertical direction and a horizontal frame extending in the width direction, that is, the left-right direction. In addition, a car side pulley 2a is mounted on the lower part of the frame 16 in the vertical direction.

[0047] Figure 6 and Figure 7 It is a perspective view showing the floor assembly 10 . Figure 81 is a front view showing the bottom plate assembly 10. Fig. 9 yes Figure 8 AA cross-section view shown in FIG.

[0048] like Figures 6 to 9 As shown, the floor assembly 10 includes a floor main body 21, a fixing bracket 23, and a floor panel 22. The floor panel 22 is placed on the upper surface of the floor main body 21 and the fixing bracket 23 in the vertical direction. The floor main body 21 is formed in a substantially rectangular shape. The floor main body 21 is surrounded by a frame 16 (refer to Figure 3 and Figure 4 ) support. In addition, the size of the bottom plate body 21 is set to the same size as the bottom plate bodies of other cars. The bottom plate body 21 is shared with the bottom plate bodies of other cars.

[0049] The fixing bracket 23 is fixed to the front end portion, i.e., the front portion, of the bottom plate body 21 in the front-rear direction via fixing bolts 35. The fixing bracket 23 is composed of an elongated member extending in the left-right direction orthogonal to the front-rear direction. The left-right length of the fixing bracket 23 is set to be substantially the same as the left-right length of the bottom plate body 21.

[0050] Fig.10 and Fig.11 The figure shows a state where the rocker 42 , the side panel 11 , and the front side panel 14 are provided on the floor assembly 10 .

[0051] like Fig.10 and Fig.11 As shown, a door sill bracket 41 is fixed to a surface of the fixing bracket 23 opposite to the surface facing the bottom plate body 21, that is, the front surface in the front-rear direction. A door sill 42 is provided on the upper surface of the door sill bracket 41 in the up-down direction to movably support the door portion 13. That is, the door sill 42 is fixed to the bottom plate body 21 via the fixing bracket 23.

[0052] In addition, if Fig.10 and Fig.11 As shown, a plurality of side panels 11 and a front side panel 14 are mounted on the upper portion in the vertical direction of the floor assembly 10. The plurality of side panels 11 are mounted on the outer edge portion of the floor main body 21 in the floor assembly 10. In addition, the plurality of side panels 11 are mounted on three outer edge portions of the four outer edge portions of the floor main body 21 except the front portion.

[0053] The front side panel 14 provided with the entrance and exit 14a and the operation panel relative to the side panel 11 is placed and mounted on the fixing bracket 23. The fixing bracket 23 is formed to match the size of the door sill 42 and the front side panel 14. Therefore, when the size of the door sill 42 and the front side panel 14 is changed, only the size of the fixing bracket 23 is changed in the floor assembly 10, and the size of the floor main body 21 does not need to be changed. That is, even if the size of the front side panel 14 changes, the floor main body 21 can be used in common with the floor main body of a different car. As a result, it is possible to provide a car 2 that can flexibly respond to changes in customer use.

[0054] In addition, since the door sill 42 is fixed to the bottom plate body 21 via the fixing bracket 23, when a load is applied to the door sill 42, a large bending moment occurs at the fixing bracket 23. Figure 6 , Figure 7 and Fig. 9 As shown, a plurality of reinforcing members 31 are provided on the fixed bracket 23. The plurality of reinforcing members 31 are provided at intervals in the left-right direction, that is, the width direction, of the fixed bracket 23. In addition, the reinforcing members 31 are provided at least at positions corresponding to the entrances and exits 14a of the fixed bracket 23 for people and goods to enter and exit.

[0055] Next, for the detailed structure of the fixing bracket 23 and the reinforcing member 31, refer to Fig.12 and Fig.13 Provide explanation.

[0056] Fig.12 It is a cross-sectional view showing the fixing bracket 23 in an enlarged manner. Fig.13 It is a plan view of the fixing bracket 23 and the door sill 42 as viewed from below in the up-down direction.

[0057] like Fig.12 and Fig.13 As shown, the fixing bracket 23 has a first fixing surface 25, a second fixing surface 26, a lower surface 27, and an upper surface 28. The first fixing surface 25 and the second fixing surface 26 are opposite to each other in the front-rear direction. The first fixing surface 25 is connected and fixed to the front part of the bottom plate body 21 via a fixing bolt 35. The second fixing surface 26 is connected and fixed to the door sill bracket 41 via the fixing bolt 35. The first fixing surface 25 and the second fixing surface 26 are arranged in parallel with the up-down direction.

[0058] The upper surface 28 is connected at right angles to the upper ends of the first fixed surface 25 and the second fixed surface 26 in the vertical direction. The bottom plate 22 can be placed on the upper surface 28. Therefore, the shape of the fixing bracket 23 cut in the vertical direction is formed into a substantially U-shaped shape. In addition, the lower surface 27 is connected at right angles to the second fixed surface 26 at the lower end of the second fixed surface 26 in the vertical direction. The lower surface 27 protrudes from the lower end of the second fixed surface 26 toward the first fixed surface 25. The lower surface 27 and the upper surface 28 are opposite to each other in the vertical direction.

[0059] The reinforcement member 31 is inserted between the first fixing surface portion 25 and the second fixing surface portion 26 of the fixing bracket 23. The reinforcement member 31 is fastened and fixed to the fixing bracket 23 by fixing bolts 35.

[0060] Here, the case where the reinforcing member 31 is fixed in the horizontal direction, that is, fixed to the first fixed surface 25 and the second fixed surface 26 is described. In order to insert the reinforcing member 31 between the first fixed surface 25 and the second fixed surface 26 in the fixing bracket 23, the length of the reinforcing member 31 in the front-to-back direction needs to be slightly shorter than the interval between the first fixed surface 25 and the second fixed surface 26. When the reinforcing member 31 is fastened and fixed, when the fixing bolt 35 is tightened, the first fixed surface 25 and the second fixed surface 26 are deformed in a direction approaching each other. Therefore, the first fixed surface 25 and / or the second fixed surface 26 are tilted relative to the up-down direction. As a result, the door sill 42 fixed to the second fixed surface 26 is tilted relative to the horizontal direction, and the front end portion of the door sill 42 in the front-to-back direction hangs down below the up-down direction.

[0061] In contrast, in the car 2 of this example, the reinforcing member 31 is fixed to the fixing bracket 23 at two axes in different directions. Hereinafter, the detailed structure of the reinforcing member 31 in the car 2 of this example and the method of fixing the reinforcing member 31 will be described.

[0062] The shape of the reinforcing member 31 as viewed from the left and right directions is formed into a substantially right triangle shape. The reinforcing member 31 includes a first face portion 31a and a second face portion 31b. The first face portion 31a is a lower face portion in the vertical direction of the reinforcing member 31. The second face portion 31b is connected to an end portion of the first face portion 31a on the rear end side in the front-rear direction. The second face portion 31b is bent substantially vertically from an end portion of the first face portion 31a toward the upper side in the vertical direction.

[0063] When the reinforcing member 31 is inserted between the first fixing surface portion 25 and the second fixing surface portion 26 of the fixing bracket 23, the first surface portion 31a faces the lower surface portion 27 of the fixing bracket 23, and the second surface portion 31b faces the first fixing surface portion 25 of the fixing bracket 23. In addition, the first surface portion 31a is connected and fixed to the lower surface portion 27 via the fixing bolts 35, and the second surface portion 31b is connected and fixed to the first fixing surface portion 25 via the fixing bolts 35. That is, the reinforcing member 31 is fixed to the fixing bracket 23 at two locations, namely, the first fixing surface portion 25 and the lower surface portion 27. Thus, the reinforcing member 31 is fixed between the first fixing surface portion 25 and the second fixing surface portion 26 in the fixing bracket 23.

[0064] As described above, the first surface 31a and the second surface 31b fixed to the fixing bracket 23 are orthogonal to each other. That is, the two fixing bolts 35 fixing the reinforcing member 31 are arranged so that their axial directions are orthogonal to each other. When the two fixing bolts 35 attached to the first surface 31a and the second surface 31b are tightened, the load from the fixing bolts 35 is applied to the first fixing surface 25 and the lower surface 27 orthogonal to the first fixing surface 25 in the fixing bracket 23. Therefore, even if the two fixing bolts 35 are tightened, the interval between the first fixing surface 25 and the second fixing surface 26 does not change.

[0065] Thus, even when the reinforcement member 31 is fixed to the fixing bracket 23, the first fixing surface 25 and the second fixing surface 26 can be kept parallel to the vertical direction. As a result, the door sill 42 fixed to the second fixing surface 26 via the fixing bolts 35 can be prevented from tilting relative to the horizontal direction.

[0066] Furthermore, by fixing the reinforcement member 31 inside the fixing bracket 23 , even when a load is applied to the door sill 42 , it is possible to prevent the fixing bracket 23 from being deformed by a bending moment.

[0067] In addition, in the car 2 of this example, an example is described in which the second surface 31b of the reinforcing member 31 is fixed to the first fixed surface 25 of the fixed bracket 23, but the present invention is not limited to this, and the second surface 31b may be fixed to the second fixed surface 26 of the fixed bracket 23. In addition, an example is described in which the lower surface 27 of the first surface 31a of the fixed reinforcing member 31 in the fixed bracket 23 is formed on the second fixed surface 26 side, but the present invention is not limited to this, and the lower surface 27 may be formed on the first fixed surface 25 side.

[0068] Furthermore, an example in which the reinforcing member 31 is formed into a substantially right triangle shape is described, but the present invention is not limited thereto, and the reinforcing member 31 may be formed into various other shapes such as a quadrilateral or a U-shape. In addition, an example in which the axial directions of the two fixing bolts 35 fixing the reinforcing member 31 are orthogonal is described, but the present invention is not limited thereto, and the axial directions of the two fixing bolts 35 may cross each other.

[0069] In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the spirit of the invention.

[0070] Furthermore, in the above-described embodiment, an example in which a fixing bolt is used as an example of a fixing member is described, but the present invention is not limited to this, and a rivet may be used as a fixing member.

[0071] As an elevator, it is also applicable to a multi-car elevator in which a plurality of cars move up and down in one hoistway.

[0072] In addition, in this specification, terms such as "parallel" and "orthogonal" are used, but they do not only mean strict "parallel" and "orthogonal", but can also mean "approximately parallel" and "approximately orthogonal" within the range that can exert their functions, including "parallel" and "orthogonal".
