Description

Technical Field

[0001] The present invention relates to an assembly jig for an elevator three-sided frame.

Background Art

[0002] The elevator three-sided frame is installed at the entrance and exit of the elevator landing. The elevator three-sided frame is assembled by connecting an upper frame and a pair of vertical frames in a substantially U-shape, and is attached to the surfaces in three directions (up, left, and right) of the entrance and exit of the landing. The elevator three-sided frame requires relatively high assembly accuracy in order to enhance the aesthetic appearance.

[0003] The elevator three-sided frame may be carried into the installation site in an assembled state. However, in the case of an elevator with a large landing entrance and exit, the elevator three-sided frame also becomes large, and the transport efficiency of the elevator three-sided frame deteriorates. Therefore, it has been considered to assemble the elevator three-sided frame at the installation site.

[0004] [[ID=第十九]] Patent Document 1 discloses an elevator three-sided frame installation device used when assembling and installing an elevator three-sided frame at an installation site. The elevator three-sided frame installation device disclosed in Patent Document 1 includes an upper installation device and a lower installation device arranged to connect between a pair of vertical frames. The upper installation device and the lower installation device each have a long body extending to connect between a pair of vertical frames, a pair of gripping devices provided on the long body to grip each of the pair of vertical frames, and a connecting member provided at an intermediate portion of the long body to adjust the dimension between the pair of gripping devices.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, the upper and lower mounting devices described in Patent Document 1 were large devices, each larger than the width of the elevator's three-sided frame. Therefore, it was cumbersome to transport the upper and lower mounting devices, for example, to the landing entrance on a high floor. In addition, it was necessary to secure a large space for transporting the upper and lower mounting devices, which increased transportation costs.

[0007] The objective of the present invention is to provide a compact and portable assembly jig for an elevator three-sided frame, taking into consideration the above-mentioned problems. [Means for solving the problem]

[0008] To achieve at least one of the above-mentioned objectives, an elevator three-sided frame assembly jig reflecting one aspect of the present invention is used when assembling an elevator three-sided frame by connecting the upper frame and a pair of vertical frames in a substantially U-shape. The elevator three-sided frame assembly jig comprises a contact surface to which one end face in the depth direction of the upper frame and vertical frame abuts, and an outer corner engaging portion and an inner corner engaging portion protruding from the contact surface. The outer corner engaging portion engages with the outer surface of the corner formed by the upper frame and vertical frame. The inner corner engaging portion engages with the inner surface of the corner formed by the upper frame and vertical frame. [Effects of the Invention]

[0009] According to the present invention, the assembly jig for the elevator three-sided frame can be made compact and easy to carry. Furthermore, issues, configurations, and effects other than those mentioned above will be clarified by the following description of the embodiments. [Brief explanation of the drawing]

[Figure 6] This is a perspective view of the assembly jig body according to a second embodiment of the present invention. [Modes for carrying out the invention]

[0011] 1. First Embodiment The assembly jig for the elevator three-sided frame according to the first embodiment of the present invention will be described below with reference to Figures 1 to 5. In each figure, common components are denoted by the same reference numerals.

[0012] [Construction of the elevator's three-sided frame] First, the configuration of the elevator three-sided frame assembled using the assembly jig according to the first embodiment of the present invention will be described with reference to Figure 1. Figure 1 is a perspective view of the elevator's three-sided frame.

[0013] The elevator three-sided frame 50 shown in Figure 1 is installed at the entrance / exit of the elevator landing. The elevator three-sided frame 50 has an upper frame 51 and a pair of vertical frames 52, 53 connected to the upper frame 51. The pair of vertical frames 52, 53 face each other with a predetermined distance between them. When viewed from the front of the elevator landing entrance / exit, the upper frame 51 and the pair of vertical frames 52, 53 are formed in a roughly U-shape.

[0014] Hereinafter, the direction in which the pair of vertical frames 52 and 53 face each other will be defined as the left-right direction. The direction approximately perpendicular to the up-down and left-right directions will be defined as the depth direction. Passengers pass through the three-sided elevator frame 50 in the depth direction and board an elevator car (not shown).

[0015] The upper frame 51 is made of a plate body having a plane substantially perpendicular to the vertical direction and is formed into a rectangle long in the left-right direction. The plane facing upward of the upper frame 51 forms the outer surface of the elevator three-sided frame 50, and the plane facing downward of the upper frame 51 forms the inner surface (appearance surface) of the elevator three-sided frame 50. Hereinafter, the plane facing upward of the upper frame 51 is referred to as the outer surface 51a, and the plane facing downward of the upper frame 51 is referred to as the inner surface 51b.

[0016] The pair of vertical frames 52 and 53 are each made of a plate body having a plane substantially perpendicular to the left-right direction and are formed into a rectangle long in the vertical direction. The upper ends of the pair of vertical frames 52 and 53 are fastened to both ends in the left-right direction of the upper frame 51 using screws (bolts and nuts), respectively. Therefore, through holes through which the screws pass are formed at both ends in the left-right direction of the upper frame 51 and the upper ends of the pair of vertical frames 52 and 53.

[0017] The plane of the vertical frame 52 facing the vertical frame 53 side forms the inner surface (appearance surface) of the elevator three-sided frame 50, and the plane of the vertical frame 52 facing the side opposite to the vertical frame 53 side forms the outer surface of the elevator three-sided frame 50. Hereinafter, the plane of the vertical frame 52 facing the side opposite to the vertical frame 53 side is referred to as the outer surface 52a, and the plane of the vertical frame 52 facing the vertical frame 53 side is referred to as the inner surface 52b.

[0018] ]>Also, the plane of the vertical frame 53 facing the vertical frame 5@ side forms the inner surface (appearance surface) of the elevator three-sided frame 50, and the plane of the vertical frame 53 facing the side opposite to the vertical frame 52 side forms the outer surface of the elevator three-sided frame 50. Hereinafter, the plane of the vertical frame 53 facing the side opposite to the vertical frame 52 side is referred to as the outer surface 53a, and the plane of the vertical frame 53 facing the vertical frame 52 side is referred to as the inner surface 53b.

[0019] The inner surfaces 52b and 53b of the pair of vertical frames 52 and 53 are inclined so as to approach each other from one end to the other end in the depth direction (see Fig. 5). One end surface in the depth direction of the pair of vertical frames 52 and 53 is the appearance surface facing the elevator landing side (hall side). Therefore, the inner surfaces 52b and 53b of the pair of vertical frames 52 and 53 are inclined so as to widen the landing entrance as they face the elevator landing side.

[0020] [Configuration of Assembly Jig for Elevator Three-Side Frame] Next, the configuration of the assembly jig for the elevator three-side frame will be described with reference to FIGS. 2 and 3. FIG. 2 is a perspective view of the assembly jig for the elevator three-side frame according to the first embodiment. FIG. 3 is a perspective view of the angle adjustment member in the assembly jig for the elevator three-side frame.

[0021] The assembly jig for the elevator three-side frame according to the first embodiment includes an assembly jig body 1 (see FIG. 2) for positioning the upper frame 51 and the vertical frame 52, an assembly jig body for positioning the upper frame 51 and the vertical frame 53, and an angle adjustment member 2 (see FIG. 3). The assembly jig body for positioning the upper frame 51 and the vertical frame 53 is formed symmetrically with the assembly jig body 1 in the left-right direction. Here, the configuration of the assembly jig body 1 and the angle adjustment member 2 will be described, and the description of the assembly jig body for positioning the upper frame 51 and the vertical frame 53 will be omitted.

[0022] As shown in FIG. 2, the assembly jig body 1 includes a base portion 11, an outer corner engagement portion 12, and an inner corner engagement portion 13. The assembly jig body 1 is made of a resin such as engineering plastic, for example. Note that the material of the assembly jig according to the present invention is not limited to resin, and for example, an elastomer, a rubber material, or a metal may be adopted.

[0023] The base portion 11 is formed in a substantially rectangular plate shape. The base portion 11 has a first side 11a and a second side 11b that face each other, and a third side 11c and a fourth side 11d that face each other. Also, one plane of the base portion 11 is a contact surface 11e. One end surface in the depth direction of the upper frame 51 and the vertical frame 52 abuts against the contact surface 11e. The other plane of the base portion 11 abuts against a plane such as the floor at the installation site of the elevator three-side frame 50, for example.

[0024] The outer corner engagement portion 12 and the inner corner engagement portion 13 protrude from the contact surface 11e of the base portion 11. The outer corner engagement portion 12 is formed in a substantially L-shape when viewed from the front of the contact surface 11e. The outer corner engagement portion 12 engages with the outer surfaces (outer surfaces 51a and 52a) at the corners of the elevator three-sided frame 50 formed by the upper frame 51 and the vertical frame 52.

[0025] The outer corner engagement portion 12 has an upper frame engagement piece 14 and a vertical frame engagement piece 15. The upper frame engagement piece 14 is formed in a substantially rectangular parallelepiped shape that extends along the first side 11a of the base portion 11. The upper frame engagement piece 14 has an upper frame engagement surface 14a. The upper frame engagement surface 14a is a plane substantially perpendicular to the contact surface 11e of the base portion 11 and faces the inner corner engagement portion 13 at a predetermined distance. The upper frame engagement surface 14a engages with the outer surface 51a of the upper frame 51 (see Figure 1).

[0026] A notch 17 is formed in the upper frame engaging piece 14. The notch 17 cuts out most of the upper frame engaging piece 14 on the side facing the vertical frame engaging piece 15. The notch 17 exposes the screw fastening portion of the upper frame 51 and the vertical frame 52, which are located in a position overlapping with the upper frame engaging piece 14.

[0027] The vertical frame engaging piece 15 is formed in a substantially rectangular parallelepiped shape extending along the third side 11c of the base portion 11. The vertical frame engaging piece 15 has a vertical frame engaging surface 15a. The vertical frame engaging surface 15a is a plane substantially perpendicular to the contact surface 11e of the base portion 11 and the upper frame engaging surface 14a of the upper frame engaging piece 14, and faces the corner inner surface engaging portion 13 at a specific distance. The vertical frame engaging surface 15a engages with the outer surface 52a of the vertical frame 52 (see Figure 1).

[0028] The corner inner surface engaging portion 13 is formed in a substantially rectangular shape when viewed from the front with the contact surface 11e facing forward. The corner inner surface engaging portion 13 engages with the inner surfaces (inner surfaces 51b and 52b) at the corners of the elevator three-sided frame 50 formed by the upper frame 51 and the vertical frame 52. That is, the upper frame 51 is inserted between the upper frame engaging piece 14 and the corner inner surface engaging portion 13. The vertical frame 52 is inserted between the vertical frame engaging piece 15 and the corner inner surface engaging portion 13.

[0029] The inner corner engagement portion 13 has an upper frame engagement surface 13a and a vertical frame engagement surface 13b. The upper frame engagement surface 13a is a plane substantially parallel to the upper frame engagement surface 14a of the upper frame engagement piece 14, and faces the upper frame engagement surface 14a at a predetermined distance. The upper frame engagement surface 13a engages with the inner surface 51b (see Figure 1) of the upper frame 51. The inner corner engagement portion 13 and the upper frame engagement piece 14 stand upright, sandwiching the upper frame 51. At this time, one end surface in the depth direction of the upper frame 51 abuts against the contact surface 11e of the base portion 11.

[0030] The vertical frame engagement surface 13b faces the vertical frame engagement surface 15a at a specific distance. The vertical frame engagement surface 13b is an inclined surface that increases the distance between it and the vertical frame engagement piece 15 (vertical frame engagement surface 15a) as it moves away from the contact surface 11e. The vertical frame engagement surface 13b engages with the inner surface 52b of the vertical frame 52 (see Figure 1) via the angle adjustment member 2, which will be described later.

[0031] The inclination angle of the inner surface 52b (see Figure 1) of the vertical frame 52 varies depending on the specifications of the elevator landing entrance. Therefore, in this embodiment, an angle adjustment member 2 is used to form an engagement surface corresponding to the inclination of the inner surface 52b of the vertical frame 52.

[0032] As shown in Figure 3, the angle adjustment member 2 is a wedge-shaped member. The angle adjustment member 2 has a first engagement surface 2a and a second engagement surface 2b. The first engagement surface 2a and the second engagement surface 2b form an acute angle that becomes the tip of the angle adjustment member 2. The first engagement surface 2a contacts the inner surface 52b of the vertical frame 52. The second engagement surface 2b contacts the vertical frame engagement surface 13b of the corner inner surface engagement portion 13.

[0033] When the angle adjustment member 2 is inserted between the inner surface 52b of the vertical frame 52 and the vertical frame engagement surface 13b of the inner corner engagement portion 13, the angle adjustment member 2 presses the vertical frame 52 toward the vertical frame engagement piece 15. As a result, the outer surface 51a of the vertical frame 52 engages with the vertical frame engagement surface 15a of the vertical frame engagement piece 15. Consequently, the vertical frame 52 is positioned. The angle adjustment member 2 and the vertical frame engagement piece 15 also allow the vertical frame 52 to stand on its own by sandwiching it. At this time, one end surface of the vertical frame 52 in the depth direction contacts the contact surface 11e of the base portion 11.

[0034] Furthermore, when manufacturing assembly jig bodies 1 according to the specifications of the elevator landing entrance, the inclination angle of the vertical frame engagement surface 13b should be the same as the inclination angle of the inner surface 52b of the vertical frame 52. In this case, the angle adjustment member 2 is not required. In addition, some elevator landing entrance specifications do not have an inclined inner surface 52b of the vertical frame 52. In that case, the vertical frame engagement surface 13b is not inclined and is formed as a plane approximately perpendicular to the contact surface 11e. In this case as well, the angle adjustment member 2 is not required.

[0035] [Assembly work for the elevator's three-sided frame] Next, the assembly work of the elevator three-sided frame 50 using the elevator three-sided frame assembly jig according to the first embodiment will be described with reference to Figures 4 and 5. Figure 4 is a perspective view of the elevator three-sided frame assembly jig according to the first embodiment, as seen from the outside of the elevator three-sided frame 50. Figure 5 is a perspective view of the elevator three-sided frame assembly jig according to the first embodiment, as seen from the inside of the elevator three-sided frame 50.

[0036] First, the worker inserts the upper frame 51 between the corner inner surface engaging portion 13 and the upper frame engaging piece 14 of the assembly jig body 1. As a result, the outer surface 51a of the upper frame 51 engages with the upper frame engaging surface 14a of the upper frame engaging piece 14 (see Figure 4). Also, the inner surface 51b of the upper frame 51 engages with the upper frame engaging surface 13a of the corner inner surface engaging portion 13 (see Figure 5). Then, one end surface of the upper frame 51 in the depth direction contacts the contact surface of the base portion 11, and one end surface of the upper frame 51 in the left-right direction contacts the vertical frame engaging surface 15a of the vertical frame engaging piece 15. As a result, the upper frame 51 is positioned in a self-supporting state.

[0037] Next, the worker inserts the vertical frame 52 between the corner inner surface engaging portion 13 and the vertical frame engaging piece 15 of the assembly jig body 1. Then, the worker brings the upper end of the vertical frame 52 into contact with the inner surface 52b of the vertical frame 52 (see Figure 5). As a result, the outer surface 52a of the vertical frame 52 faces the vertical frame engaging surface 15a of the vertical frame engaging piece 15. Also, as shown in Figure 5, the inner surface 52b of the vertical frame 52 faces the vertical frame engaging surface 13b of the corner inner surface engaging portion 13 (see Figure 5). Finally, one end surface in the depth direction of the upper frame 51 contacts the contact surface of the base portion 11.

[0038] Next, the worker inserts the angle adjustment member 2 between the inner surface 52b of the vertical frame 52 and the vertical frame engagement surface 13b of the inner corner engagement portion 13 (see Figure 5). As a result, the first engagement surface 2a of the angle adjustment member 2 contacts the inner surface 52b of the vertical frame 52, and the second engagement surface 2b contacts the vertical frame engagement surface 13b of the inner corner engagement portion 13. The angle adjustment member 2 then presses the vertical frame 52 towards the vertical frame engagement piece 15. As a result, the outer surface 52a of the vertical frame 52 engages with the vertical frame engagement surface 15a of the vertical frame engagement piece 15. Consequently, the vertical frame 52 is positioned in a self-supporting state.

[0039] Next, the worker uses an assembly jig body (not shown) that is symmetrically formed with the assembly jig body 1 to position the upper frame 51 and the vertical frame 53. As a result, the vertical frame 53 is positioned in a self-supporting state.

[0040] Next, the worker fastens the upper frame 51 and the vertical frame 52 using screws. At this time, the notch 17 exposes the screw fastening portion of the upper frame 51 and the vertical frame 52 that is in a position overlapping with the upper frame engaging piece 14 (see Figure 4). This allows the worker to fasten all the screw fastening portions with the upper frame 51 and the vertical frame 52 positioned on the assembly jig body 1. The worker can also fasten all the screw fastening portions with the upper frame 51 and the vertical frame 53 positioned on an assembly jig body (not shown).

[0041] Furthermore, the assembly jig body 1 and the upper frame 51 and vertical frames 52, 53 positioned on the assembly body (not shown) are self-supporting. Therefore, the worker does not need to use any part of their body to support the upper frame 51 and vertical frame 52 to prevent them from falling over. Consequently, the worker can perform the fastening work in a position where the screw fastening parts of the upper frame 51 and vertical frame 52 (vertical frame 53) are easily visible.

[0042] As described above, by using the elevator three-sided frame assembly jig according to the first embodiment, the positioning of the upper frame 51 and vertical frame 52, and the upper frame 51 and vertical frame 53 can be easily performed when assembling the elevator three-sided frame 50. This improves the work efficiency of the elevator three-sided frame 50 assembly work.

[0043] Furthermore, the assembly jig body 1 of the elevator three-sided frame assembly jig according to the first embodiment can be made smaller because it engages with the corners of the elevator three-sided frame 50. Therefore, the elevator three-sided frame assembly jig according to the first embodiment can be made compact and easy to carry. In addition, the elevator three-sided frame assembly jig can reduce the space required for transportation, thereby reducing transportation costs.

[0044] Furthermore, the assembly jig for the elevator three-sided frame according to the first embodiment may include spacers to be interposed between the vertical frames 52 and 53 and a flat surface such as the floor. The height of these spacers should be the same as the height of the base portion 11 of the assembly jig body 1. This allows the vertical frames 52 and 53 to be positioned parallel to the flat surface such as the floor, further improving workability. In addition, to reduce the size of the spacers, it is preferable to provide a spacer for each of the vertical frames 52 and 53.

[0045] 2. Second Embodiment [Configuration of the assembly jig for the elevator's three-sided frame] Next, the configuration of the assembly jig for the elevator three-sided frame according to the second embodiment of the present invention will be described with reference to Figure 6. Figure 6 is a perspective view of the assembly jig body for the elevator three-sided frame according to the second embodiment. In Figure 6, components common to the first embodiment are denoted by the same reference numerals.

[0046] The assembly jig for the elevator three-sided frame according to the second embodiment comprises an assembly jig body 3 for positioning the upper frame 51 and the vertical frame 52, an assembly jig body (not shown) for positioning the upper frame 51 and the vertical frame 53, and an angle adjustment member 2 (see Figure 3). The assembly jig body for positioning the upper frame 51 and the vertical frame 53 according to the second embodiment is formed symmetrically with the assembly jig body 3. Here, the configuration of the assembly jig body 3 will be described, and the description of the assembly jig body for positioning the upper frame 51 and the vertical frame 53 and the angle adjustment member 2 according to the second embodiment will be omitted.

[0047] As shown in Figure 6, the assembly jig body 3 comprises a base portion 31, an outer corner engagement portion 32, and an inner corner engagement portion 13. The inner corner engagement portion 13 is the same as in the first embodiment. The assembly jig body 3 is made of a resin such as engineering plastic.

[0048] The base portion 31 is formed in the shape of a roughly rectangular plate. The base portion 31 has a first side 31a and a second side 31b that face each other, and a third side 31c and a fourth side 31d that face each other. One of the planes of the base portion 31 is a contact surface 31e. One end face in the depth direction of the upper frame 51 and the vertical frame 52 abuts against the contact surface 31e. The other plane of the base portion 31 abuts against a plane, such as the floor at the installation site of the elevator three-sided frame 50.

[0049] An opening 37 is formed in the base portion 31. The opening 37 is formed as a rectangle that extends from approximately the center of the base portion 31 to the third side 31c. The opening 37 exposes at least the contact portion between the upper frame 51 and the vertical frame 52 at one end face in the depth direction at the corner of the elevator three-sided frame 50 formed by the upper frame 51 and the vertical frame 52.

[0050] The outer corner engagement portion 32 and the inner corner engagement portion 13 protrude from the contact surface 31e of the base portion 31. The outer corner engagement portion 32 is formed in a substantially L-shape when viewed from the front of the contact surface 31e. The outer corner engagement portion 32 engages with the outer surfaces (outer surfaces 51a and 52a) at the corners of the elevator three-sided frame 50 formed by the upper frame 51 and the vertical frame 52.

[0051] The outer corner engagement portion 32 has an upper frame engagement piece 14 and a vertical frame engagement piece 35. The upper frame engagement piece 14 is the same as in the first embodiment. The vertical frame engagement piece 35 is formed in a substantially rectangular parallelepiped shape that extends along the third side 31c of the base portion 31. The vertical frame engagement piece 35 has a vertical frame engagement surface 35a. The vertical frame engagement surface 35a is a plane substantially perpendicular to the contact surface 31e of the base portion 31 and the upper frame engagement surface 14a of the upper frame engagement piece 14, and faces the inner corner engagement portion 13 at a specific distance. The vertical frame engagement surface 35a engages with the outer surface 52a of the vertical frame 52 (see Figure 1).

[0052] An opening 38 is formed in the vertical frame engaging piece 35. The opening 38 is located in the thickness direction of the base portion 31, in the portion opposite to the opening 37. The opening 38 is in communication with the opening 37. The opening 38 exposes at least the contact portion between the upper frame 51 and the vertical frame 52 on the outer surface of the corner of the elevator three-sided frame 50 formed by the upper frame 51 and the vertical frame 52.

[0053] The elevator three-sided frame assembly jig according to the second embodiment, like the elevator three-sided frame assembly jig according to the first embodiment, can improve the workability of the elevator three-sided frame 50 assembly work. Furthermore, the assembly jig body 3 of the elevator three-sided frame assembly jig according to the second embodiment can be made smaller because it engages with the corners of the elevator three-sided frame 50. Therefore, the elevator three-sided frame assembly jig according to the second embodiment can be made compact and easy to carry. In addition, the space required for transporting the elevator three-sided frame assembly jig can be reduced, thereby reducing transportation costs.

[0054] Furthermore, the assembly jig body 3 according to the second embodiment has an opening 37 formed in the base portion 31. This allows the worker to insert their finger into the opening 37 and touch one end face in the depth direction at the corner of the elevator three-sided frame 50. As a result, it is possible to confirm that there is no step difference between the upper frame 51 and the vertical frame 52 at one end face in the depth direction (so-called surface alignment). Therefore, the assembly jig body 3 according to the second embodiment can improve the assembly accuracy of the elevator three-sided frame 50.

[0055] Furthermore, the assembly jig body 3 according to the second embodiment has an opening 38 formed in the vertical frame engaging piece 35. This allows the worker to insert their finger into the opening 37 and touch the outer surface of the corner of the elevator three-sided frame 50. As a result, it is possible to confirm that there is no step difference between the upper frame 51 and the vertical frame 52 on the outer surface of the corner (so-called surface alignment). Therefore, the assembly jig body 3 according to the second embodiment can improve the assembly accuracy of the elevator three-sided frame 50.

[0056] 3. Summary (1) As described above, the elevator three-sided frame assembly jig according to the first embodiment described above is used when assembling the elevator three-sided frame 50 by connecting the upper frame 51 and a pair of vertical frames 52, 53 in a substantially U-shape. The elevator three-sided frame assembly jig comprises a contact surface 11e to which one end surface in the depth direction of the upper frame 51 and the vertical frame 52 (53) abuts, and an outer corner engagement portion 12 and an inner corner engagement portion 13 protruding from the contact surface 11e. The outer corner engagement portion 12 engages with the outer surface of the corner formed by the upper frame 51 and the vertical frame 52 (53). The inner corner engagement portion 13 engages with the inner surface of the corner formed by the upper frame 51 and the vertical frame 52 (53). This makes it easy to position the upper frame 51 and the vertical frame 52 (53), improving the work efficiency of the elevator three-sided frame 50 assembly. In addition, the assembly jig for the elevator three-sided frame can be made smaller, more compact, and easier to carry. Furthermore, the assembly jig for the elevator three-sided frame requires less space for transport, thus reducing transportation costs.

[0057] (2) Furthermore, the outer corner engagement portion 12 and inner corner engagement portion 13 according to the first embodiment described above enable the upper frame 51 and vertical frame 52 (53) to stand upright with one end face in the depth direction facing downwards. This allows workers to perform the connection work in a position where the connection between the upper frame 51 and the vertical frame 52 (53) is easily visible.

[0058] (3) Furthermore, the corner outer engagement portion 12 according to the first embodiment described above has a notch 17 that exposes the connecting portion between the upper frame 51 and the vertical frame 52 (53). This allows the worker to complete the fastening work while the upper frame 51 and vertical frame 52 (53) are positioned.

[0059] (4) Furthermore, the inner corner engagement portion 13 according to the first embodiment described above has a vertical frame engagement surface 13b that faces the vertical frame 52. The vertical frame engagement surface 13b is an inclined surface that inclins so as it moves away from the contact surface 11e, the distance between it and the outer corner engagement portion 12 increases. The assembly jig for the elevator three-sided frame according to the first embodiment includes an angle adjustment member 2 that engages with the vertical frame engagement surface 13b and the inner surface 52b of the vertical frame 52. This allows the angle adjustment member 2 to be used to form an engagement surface corresponding to the inclination of the inner surface 52b of the vertical frame 52. Therefore, the elevator three-sided frame assembly jig according to the first embodiment can be used when assembling various elevator three-sided frames in which the inclination angle of the inner surface 52b of the vertical frame 52 differs according to the specifications of the elevator landing entrance.

[0060] (5) Furthermore, the assembly jig for the elevator three-sided frame according to the first embodiment described above includes a base portion 11 that forms a contact surface 11e. The base portion 11 is formed in the shape of a plate, with one of its planes being the contact surface 11e. This allows the assembly jig (assembly jig body) for the elevator's three-sided frame to be placed on a flat surface such as the floor, and the upper frame 51 and vertical frames 52 (53) to be positioned.

[0061] (6) Furthermore, the base portion 31 according to the second embodiment described above has an opening 37 that exposes the contact portion between the upper frame 51 and the vertical frame 52(53) at one end face of the corner formed by the upper frame 51 and the vertical frame 52(53). This makes it possible to confirm that there is no step difference between the upper frame 51 and the vertical frame 52 (53) at one end face in the depth direction. Therefore, the elevator three-sided frame assembly jig according to the second embodiment can improve the assembly accuracy of the elevator three-sided frame 50.

[0062] (7) Furthermore, the corner outer engagement portion 32 according to the second embodiment described above has an opening 38 that exposes the contact portion between the upper frame 51 and the vertical frame 52(53) on the outer surface of the corner formed by the upper frame 51 and the vertical frame 52(53). This makes it possible to confirm that there is no step difference between the upper frame 51 and the vertical frame 52 (53) on the outer surface of the corner (so-called surface alignment). Therefore, the assembly jig for the elevator three-sided frame according to the second embodiment can improve the assembly accuracy of the elevator three-sided frame 50.

[0063] The above describes the embodiments of the elevator three-sided frame assembly jig, including its operation and effects. However, the elevator three-sided frame assembly jig of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the gist of the invention as described in the claims.

[0064] For example, in the embodiment described above, the upper frame 51 and the vertical frame 52 (53) are connected using screws. However, the elevator three-sided frame according to the present invention is not limited to being assembled by connection using screws, and may also be assembled by connection using, for example, crimping.

[0065] In this specification, although terms such as "parallel" and "orthogonal" are used, these do not mean only strictly "parallel" and "orthogonal," but may also refer to states that are "approximately parallel" or "approximately orthogonal," which include "parallel" and "orthogonal" and are within a range in which they can perform their functions.
