[0026] 1. Implementation Example

[0027] 1-1. Structure of the elevator

[0028] First, regarding the structure of the elevator of the embodiment example (hereinafter referred to as "this embodiment"), refer to Figure 1 Provide explanation.

[0029] Figure 1 This is a schematic structural diagram of the elevator of this example.

[0030] Figure 1 The example shown shows a so-called 2:1 roping type elevator 1. In addition, the elevator is not limited to a 2:1 roping type elevator, and can also be applied to a 1:1 roping type elevator.

[0031] 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 hoist 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.

[0032] People or goods are carried in the car 2. A car side pulley 2a is provided at the lower 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.

[0033] The hoisting machine 4 is installed at the uppermost part of the hoistway. The hoisting machine 4 has a sheave around which the main rope 3 is wound. The hoisting machine 4 raises and lowers the car 2 and the counterweight 5 via the main rope 3 in a bucket-like manner.

[0034] 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. Then, the main rope 3 is wound from one end in the order of the car side pulley 2a, the rope sheave of the hoist 4, and the counterweight side pulley 5a.

[0035] 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 on the upper part of the hoistway in the same manner as the one end. Driven by the hoist 4, the car 2 and the counterweight 5 move up and down in the hoistway.

[0036] The car 2 includes a floor assembly 10 as a floor surface of the car room, side panels 11, a ceiling 12, and a door portion 13. The car 2 also includes a frame member (not shown) that supports the floor assembly 10. The floor assembly 10 and the ceiling 12 are disposed opposite to each other in the up-down direction. The side panels 11 are erected around the floor assembly 10 and the ceiling 12. An entrance is provided on one of the side panels 11 surrounding the floor assembly 10. The door portion 13 is provided at the entrance so as to be openable and closable. The floor assembly 10, the side panels 11, the ceiling 12, and the door portion 13 constitute a car room in the car 2 that carries people and cargo.

[0037] 1-2. Structural example of floor assembly

[0038] Next, refer to Figure 2 to Figure 6 The structure of the floor assembly 10 of this example will be described.

[0039] Figure 2 is a perspective view showing the floor assembly 10. Figure 3 It is an exploded perspective view showing the floor assembly 10 . Figure 4 2 is a perspective view showing a state where the upper panel 21 is removed from the floor assembly 10. Figure 5 is a side view of the floor assembly 10 as viewed from the front. Figure 6 It is a perspective view showing the lower panel 23 .

[0040] like Figures 2 to 6 As shown in FIG. 1 , the floor assembly 10 includes a flat upper panel 21, a floor 22, a flat lower panel 23 that is opposed to the upper panel 21 in the vertical direction, and a front frame 26. In the floor assembly 10 of this example, two of each of the upper panel 21 and the lower panel 23 are provided. A plurality of positioning holes 21a for positioning with the floor 22 and the front frame 26 are formed in the upper panel 21. Similarly, a plurality of positioning holes 23a for positioning with the floor 22 and the front frame 26 are formed in the lower panel 23.

[0041] The floor panel 22 is disposed between the upper panel 21 and the lower panel 23. The floor panel 22 is bonded and fixed to the upper panel 21 and the lower panel 23 using an adhesive. The front frame 26 is disposed on the front side of the upper panel 21 where the door portion 13 is provided. Then, the front frame 26 is fixed to the upper panel 21. On the front frame 26, a door sill that movably supports the door portion 13 is fixed.

[0042] like Figure 4 and Figure 5 As shown, the floor 22 has a plurality of intermediate structures 24 and two end structures 25. The cross-sectional shape of the intermediate structures 24 and the end structures 25 cut in the vertical direction is formed into a substantially C-shaped shape. Moreover, the intermediate structures 24 and the end structures 25 are long strip-shaped components extending along the long side direction of the upper panel 21 and the lower panel 23 perpendicular to the vertical direction. In addition, the intermediate structures 24 are arranged along the width direction of the upper panel 21 and the lower panel 23 perpendicular to the vertical direction. Then, the end structures 25 are arranged at both ends of the plurality of intermediate structures 24 in the width direction.

[0043] The intermediate structure 24 has a joint surface 24a, a pair of reinforcement portions 24b, and a bent portion 24c. The joint surface 24a is formed in a substantially flat plate shape. An identification hole 24e is formed at one end of the long side direction of the joint surface 24a. By providing the identification hole 24e, the front and back of the intermediate structure 24 can be identified. In addition, an identification hole for identifying the front and back can also be provided at the other end of the long side direction of the joint surface 24a.

[0044] The reinforcing portion 24b is bent approximately vertically at both ends of the joining surface 24a in the width direction. The reinforcing portion 24b is bent approximately vertically from the end of the joining surface 24a and extends in the up-down direction. A bending portion 24c is formed at the end of the reinforcing portion 24b on the opposite side of the joining surface 24a. The bending portion 24c is bent approximately vertically from the reinforcing portion 24b and protrudes in the width direction. In addition, the bending portion 24c protrudes from the end of the reinforcing portion 24b to the side opposite to the joining surface 24a.

[0045] Floor side positioning holes 24d are formed on the joint surface 24a and the bent portion 24c. By riveting rivets 31 into the floor side positioning holes 24d provided on the intermediate structure 24 and the positioning holes 21a, 23a provided on the upper panel 21 and the lower panel 23, the intermediate structure 24 can be positioned relative to the upper panel 21 and the lower panel 23.

[0046] The bent portion 24c of the intermediate structure 24 is placed on the lower panel 23. The bent portions 24c of two adjacent intermediate structures 24 are arranged close to each other. The upper panel 21 is placed on the joint surface 24a of the intermediate structure 24.

[0047] In addition, the intermediate structure 24B disposed at the dividing position 33 between the upper panel 21 and the lower panel 23 among the plurality of intermediate structures 24 is disposed so that the vertical direction is reversed. That is, in the intermediate structure 24B, the joint surface 24a is placed at the dividing position 33 of the lower panel 23. Then, the upper panel 21 is placed on the bent portion 24c of the intermediate structure 24B. The two lower panels 23 are connected by the intermediate structure 24B. As a result, by arranging the intermediate structure 24 inverted upside down, the lower panels 23 can be easily connected, and the dividing position of the lower panel 23 can be easily designed.

[0048] Next, the end structure 25 will be described.

[0049] The end structure 25 has a joint surface 25a, a pair of reinforcing parts 25b, and a bent part 25c, similarly to the intermediate structure 24. The joint surface 25a is formed in a substantially flat plate shape. The joint surface 25a is placed on the lower panel 23. The reinforcing parts 25b are bent substantially vertically at both ends in the width direction of the joint surface 25a. The reinforcing parts 25b are bent substantially vertically from the ends of the joint surface 25a and extend in the up-down direction. A bent part 25c is formed at the end of the reinforcing part 25b on the opposite side of the joint surface 25a.

[0050] The bent portion 25c is bent substantially perpendicularly from the reinforcing portion 25b and protrudes in the width direction. Of the two bent portions 25c, the bent portion 25c disposed on the inner side in the width direction protrudes to the side opposite to the joining surface 25a. On the other hand, of the two bent portions 25c, the bent portion 25c disposed on the outer side in the width direction protrudes to the joining surface 25a side, that is, to the inner side of the floor assembly 10.

[0051] Then, floor side positioning holes 25d are formed on the joint surface 25a and the bent portion 25c in the same manner as the intermediate structure 24. By riveting the rivets 31 into the floor side positioning holes 25d provided in the end structure 25 and the positioning holes 21a and 23a provided in the upper panel 21 and the lower panel 23, the end structure 25 can be positioned relative to the upper panel 21 and the lower panel 23.

[0052] The joint surface 25a of the end structure 25 is placed on the lower panel 23, and the upper panel 21 is placed on the bent portion 25c.

[0053] Figure 7 and Figure 8 It is a perspective view showing an end portion of the floor assembly 10 in the longitudinal direction.

[0054] like Figure 7 and Figure 8 As shown, the lengths of the intermediate structures 24 and the end structures 25 constituting the floor 22 in the long-side direction are set shorter than the lengths of the upper panel 21 and the lower panel 23 in the long-side direction. Therefore, the ends of the upper panel 21 and the lower panel 23 in the long-side direction extend outward from the ends of the floor 22 (intermediate structures 24 and the end structures 25) in the long-side direction.

[0055] In addition, the bent portion 25c disposed on the outer side in the width direction of the end structure 25 protrudes inward in the width direction. Therefore, both ends of the upper panel 21 and the lower panel 23 in the width direction protrude outward in the width direction from the ends of the floor 22 (end structure 25) in the width direction.

[0056] 2. Example of floor assembly work

[0057] Next, an example of the assembly work of the floor assembly 10 having the above-mentioned structure will be described.

[0058] First, the operator sets the number of intermediate structures 24 to be installed according to the width direction lengths of the upper panel 21 and the lower panel 23 of the floor assembly 10. Figure 4 As shown, the intermediate structure 24 and the end structure 25 are placed on the lower panel 23. The intermediate structure 24B arranged at the dividing position 33 of the lower panel 23 is arranged with the vertical direction reversed. In addition, an adhesive 40 is applied to the joint surface 24a of the bent portion 24c of the intermediate structure 24 and the intermediate structure 24B, and the joint surface 25a of the end structure 25.

[0059] Then, the intermediate structures 24, 24B and the end structures 25 are positioned with the lower panel 23 by driving the rivets 31 into the positioning holes 23a and the floor side positioning holes 24d and 25d. Next, an adhesive 40 is applied to the joint surface 24a of the intermediate structure 24, the bent portion 24c of the intermediate structure 24B, and the bent portion 25c of the end structure 25. Then, the upper panel 21 is placed on the intermediate structures 24, 24B and the end structures 25, and the rivets 31 are driven in for positioning.

[0060] Next, by pressing the upper panel 21, the floor panel 22 is pressed against the upper panel 21 and the lower panel 23 by the adhesive 40. Thus, the assembly work of the floor assembly 10 is completed. In addition, the front frame 26 may be fixed to the upper panel 21 in advance, or the front frame 26 may be fixed to the upper panel 21 after the upper panel 21, the lower panel 23 and the floor panel 22 are fixed.

[0061] Thus, according to the floor assembly 10 of this example, the floor 22, the upper panel 21, and the lower panel 23 are fixed using the adhesive 40. Thus, the number of places where the floor 22, the upper panel 21, and the lower panel 23 are fastened and fixed can be reduced. As a result, the burden of the work of forming fastening holes in the floor 22, the upper panel 21, and the lower panel 23 and the work required for fastening and fixing can be reduced, and the assembly work of the floor assembly 10 can be simplified.

[0062] Next, refer to Fig. 9 and Fig.10 , a state where the floor panel 22, the upper panel 21, and the lower panel 23 are pressed and fixed using the adhesive 40 will be described.

[0063] Fig. 9 and Fig.10 It is an explanatory diagram showing the pressure-bonding operation of the floor panel 22, the upper panel 21, and the lower panel 23. Fig. 9The floor panel 122 shown in the figure is an example in which the lengths in the width direction and the long side direction are consistent with the upper panel 21 and the lower panel 23. Fig.10 The floor 22 of this example is shown.

[0064] like Fig. 9 (a) and Fig.10 As shown in (a), before crimping, adhesive 40 is applied to the entire surface of the floor panels 122, 22 that face the upper panel 21 and the lower panel 23. When the length of the floor panel 122 is consistent with that of the upper panel 21 and the lower panel 23, as shown in FIG. Fig. 9 As shown in (b), during the crimping, the adhesive 40 overflows from the ends of the upper panel 21 and the lower panel 23. Then, there is a risk that the overflowed adhesive 40 adheres to other components different from the floor 22, the upper panel 21 and the lower panel 23.

[0065] In contrast, the floor panel 22 of this example is set shorter in the longitudinal and width directions than the upper panel 21 and the lower panel 23 as described above. In addition, the ends of the upper panel 21 and the lower panel 23 extend outward from the ends of the floor panel 22. Fig.10 As shown in (b), when the pressure bonding is performed, the adhesive 40 overflowing from the floor panel 22 is contained in the upper panel 21 and the lower panel 23. As a result, the adhesive 40 can be prevented from overflowing from the ends of the upper panel 21 and the lower panel 23. As a result, the adhesive 40 can be prevented from adhering to other components.

[0066] In addition, the difference in length between the floor 22 and the ends of the upper panel 21 and the lower panel 23 is set in accordance with the amount of adhesive 40 overflowing from the floor 22. That is, the difference in length between the floor 22 and the ends of the upper panel 21 and the lower panel 23 is set to be larger than the amount of adhesive 40 overflowing from the floor 22. Thus, it is possible to reliably prevent the adhesive 40 from overflowing from the ends of the upper panel 21 and the lower panel 23 during the crimping operation.

[0067] 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 gist of the invention described in the claims.

[0068] In addition, in this specification, words such as "parallel" and "orthogonal" are used, but they do not only mean strict "parallel" and "orthogonal", but also include "parallel" and "orthogonal", and further, the states of "approximately parallel" and "approximately orthogonal" within the range that can exert their functions.
