Description

[Technical field]

[0001] The present invention relates to an assembly jig for an elevator jamb. [Background technology]

[0002] Elevator jambs are installed at the entrances and exits of elevators. They are assembled by connecting an upper frame and a pair of vertical frames in an approximately U-shape, and are attached to the three sides (top, left, and right) of the entrances and exits of elevators. Elevator jambs require relatively high assembly precision to enhance the aesthetic appearance.

[0003] Elevator jambs are sometimes delivered to the installation site in an assembled state. However, for elevators with large entrances, the elevator jambs also become large, which reduces the efficiency of transporting the elevator jambs. Therefore, it has been considered to assemble the elevator jambs at the installation site.

[0004] Patent Document 1 discloses an installation device for an elevator jamb used when assembling and installing the elevator jamb at an installation site. The installation device for an elevator jamb disclosed in Patent Document 1 includes an upper installation device and a lower installation device arranged to connect a pair of vertical frames. The upper installation device and the lower installation device each include a long body extending to connect the pair of vertical frames, a pair of gripping devices provided on the long body and gripping the pair of vertical frames, and a connecting member provided in the middle of the long body and adjusting the dimension between the pair of gripping devices.

[0005] [Patent Document 1] JP 2000-211865 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the upper installation device and the lower installation device described in Patent Document 1 were large devices larger than the width of the elevator jamb. Therefore, it was troublesome to carry the upper installation device and the lower installation device to, for example, the entrance / exit of a landing on a high floor. In addition, it was necessary to secure a large space for transporting the upper installation device and the lower installation device, which increased the transportation cost.

[0007] SUMMARY OF THE PRESENT EMBODIMENT In consideration of the above problems, an object of the present invention is to provide an assembly jig for an elevator jamb that is compact and easy to carry. [Means for solving the problem]

[0008] In order to achieve at least one of the above-mentioned objects, an assembly jig for an elevator jamb reflecting one aspect of the present invention is used when assembling an elevator jamb by connecting an upper frame and a pair of vertical frames in a generally U-shape. The assembly jig for an elevator jamb has an abutment surface where one end surface in the depth direction of the upper frame and the vertical frames abuts, and an outer corner engaging portion and an inner corner engaging portion protruding from the abutment surface. The outer corner engaging portion engages with the outer surface of the corner formed by the upper frame and the vertical frames. The inner corner engaging portion engages with the inner surface of the corner formed by the upper frame and the vertical frames. Effect of the Invention

[0009] The elevator jamb assembly jig of the present invention is compact and easy to carry. Problems, configurations and effects other than those described above will become apparent from the following description of the embodiments. [Brief description of the drawings]

[0011] 1. First embodiment Hereinafter, an assembly jig for an elevator jamb according to a first embodiment of the present invention will be described with reference to Fig. 1 to Fig. 5. Note that the same reference numerals are used to designate common members in each drawing.

[0012] [Elevator three-sided frame configuration] First, the configuration of an elevator jamb that is assembled using an assembly jig according to a first embodiment of the present invention will be described with reference to FIG. FIG. 1 is a perspective view of an elevator jamb.

[0013] The elevator jamb 50 shown in Fig. 1 is installed at the entrance / exit of an elevator hall. The elevator jamb 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. The upper frame 51 and the pair of vertical frames 52, 53 are formed in a roughly U-shape when the elevator hall entrance / exit is viewed from the front.

[0014] Hereinafter, the direction in which the pair of vertical frames 52, 53 face each other is referred to as the left-right direction. The direction substantially perpendicular to the up-down and left-right directions is referred to as the depth direction. Passengers pass through the elevator jamb 50 in the depth direction to board a car (not shown).

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

[0016] The pair of vertical frames 52, 53 are each made of a plate having a plane that is approximately vertical to the left and right, and are formed into a rectangle that is long in the up and down direction. The upper ends of the pair of vertical frames 52, 53 are fastened to both left and right ends of the upper frame 51 using screws (bolts and nuts). Therefore, both left and right ends of the upper frame 51 and the upper ends of the pair of vertical frames 52, 53 have through holes through which the screws pass.

[0017] The plane of the vertical frame 52 facing the vertical frame 53 side forms the inner surface (appearance surface) of the elevator jamb 50, and the plane of the vertical frame 52 facing the opposite side to the vertical frame 53 side forms the outer surface of the elevator jamb 50. Hereinafter, the plane of the vertical frame 52 facing the opposite side 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] Further, the plane of the vertical frame 53 facing the vertical frame 52 side forms the inner surface (appearance surface) of the elevator jamb 50, and the plane of the vertical frame 53 facing the opposite side to the vertical frame 52 side forms the outer surface of the elevator jamb 50. Hereinafter, the plane of the vertical frame 53 facing the opposite side 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, 53b of the pair of vertical frames 52, 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 face in the depth direction of the pair of vertical frames 52, 53 is a presentation face facing the elevator landing side (hall side). Therefore, the inner surfaces 52b, 53b of the pair of vertical frames 52, 53 are inclined so as to widen the landing entrance as they approach the elevator landing side.

[0020] [Configuration of elevator frame assembly jig] Next, the configuration of the elevator jamb assembly jig will be described with reference to FIGS. Fig. 2 is a perspective view of an assembly jig for an elevator jamb according to the first embodiment. Fig. 3 is a perspective view of an angle adjustment member in the assembly jig for the elevator jamb.

[0021] The assembly jig for an elevator jamb in accordance with the first embodiment comprises an assembly jig main body 1 (see FIG. 2) which positions the upper frame 51 and the vertical frames 52, an assembly jig main body which positions the upper frame 51 and the vertical frames 53, and an angle adjustment member 2 (see FIG. 3). The assembly jig main body which positions the upper frame 51 and the vertical frames 53 is formed symmetrically to the assembly jig main body 1. Here, the configurations of the assembly jig main body 1 and the angle adjustment member 2 will be described, and a description of the assembly jig main body which positions the upper frame 51 and the vertical frames 53 will be omitted.

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

[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. One flat surface of the base portion 11 is an abutment surface 11e. One end surface in the depth direction of the upper frame 51 and the vertical frame 52 abuts against the abutment surface 11e. The other flat surface of the base portion 11 abuts against a flat surface such as a floor at the installation site of the elevator jamb 50.

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

[0025] The corner outer surface 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 extending 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 abutment surface 11e of the base portion 11, and faces the corner inner surface 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 FIG. 1).

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

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

[0028] The corner inner surface engaging portion 13 is formed in a substantially rectangular shape when the abutment surface 11e is viewed from the front. The corner inner surface engaging portion 13 engages with the inner surface (inner surface 51b and inner surface 52b) at the corner of the elevator jamb 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 corner inner surface 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 that is approximately 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 specified distance. The upper frame engagement surface 13a engages with an inner surface 51b (see FIG. 1) of the upper frame 51. The corner inner surface engagement portion 13 and the upper frame engagement piece 14 sandwich the upper frame 51 to make it self-supporting. At this time, one end surface in the depth direction of the upper frame 51 abuts against the abutment 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 inclines so as to increase the distance between the vertical frame engagement piece 15 (vertical frame engagement surface 15a) as it moves away from the abutment surface 11e. The vertical frame engagement surface 13b engages with the inner surface 52b (see FIG. 1) of the vertical frame 52 via the angle adjustment member 2 described later.

[0031] The inclination angle of the inner surface 52b (see FIG. 1) of the vertical frame 52 varies depending on the specifications of the elevator hall entrance to be installed. Therefore, in this embodiment, an engagement surface according to the inclination of the inner surface 52b of the vertical frame 52 is formed using the angle adjustment member 2.

[0032] As shown in Fig. 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 portion 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 corner inner surface engagement portion 13, the angle adjustment member 2 presses the vertical frame 52 toward the vertical frame engagement piece 15. This causes the outer surface 51a of the vertical frame 52 to engage with the vertical frame engagement surface 15a of the vertical frame engagement piece 15. As a result, the vertical frame 52 is positioned. In addition, the angle adjustment member 2 and the vertical frame engagement piece 15 sandwich the vertical frame 52 to make it self-supporting. At this time, one end surface in the depth direction of the vertical frame 52 abuts against the abutment surface 11e of the base portion 11.

[0034] When manufacturing the assembly jig main body 1 according to the specifications of the elevator landing entrance / exit, the inclination angle of the vertical frame engagement surface 13b is made 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. Also, some elevator landing entrance / exit specifications do not require the inner surface 52b of the vertical frame 52 to be inclined. In this case, the vertical frame engagement surface 13b is not inclined, but is formed as a plane that is approximately perpendicular to the abutment surface 11e. In this case, the angle adjustment member 2 is also not required.

[0035] [Assembly of elevator frames] Next, the assembly work of the elevator jamb 50 using the elevator jamb assembly jig according to the first embodiment will be described with reference to FIGS. Fig. 4 is a perspective view of the elevator jam assembly jig according to the first embodiment in use, as viewed from the outside of the elevator jam 50. Fig. 5 is a perspective view of the elevator jam assembly jig according to the first embodiment in use, as viewed from the inside of the elevator jam 50.

[0036] First, the worker inserts the upper frame 51 between the corner inner surface engagement portion 13 of the assembly jig main body 1 and the upper frame engagement piece 14. As a result, the outer surface 51a of the upper frame 51 engages with the upper frame engagement surface 14a of the upper frame engagement piece 14 (see FIG. 4). Also, the inner surface 51b of the upper frame 51 engages with the upper frame engagement surface 13a of the corner inner surface engagement portion 13 (see FIG. 5). Then, one end surface of the upper frame 51 in the depth direction abuts against the abutment surface of the base portion 11, and one end surface of the upper frame 51 in the left-right direction abuts against the vertical frame engagement surface 15a of the vertical frame engagement 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 engagement portion 13 of the assembly jig main body 1 and the vertical frame engagement piece 15. Then, the worker abuts the upper end of the vertical frame 52 against the inner surface 52b of the vertical frame 52 (see FIG. 5). As a result, the outer surface 52a of the vertical frame 52 faces the vertical frame engagement surface 15a of the vertical frame engagement piece 15. Also, as shown in FIG. 5, the inner surface 52b of the vertical frame 52 faces the vertical frame engagement surface 13b of the corner inner surface engagement portion 13 (see FIG. 5). Then, one end surface in the depth direction of the upper frame 51 abuts against the abutment 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 corner inner surface engagement portion 13 (see FIG. 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 corner inner surface engagement portion 13. The angle adjustment member 2 then presses the vertical frame 52 toward 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. As a result, the vertical frame 52 is positioned in a self-supporting state.

[0039] Next, the worker positions the upper frame 51 and the vertical frame 53 using an assembly jig main body (not shown) formed symmetrically to the assembly jig main body 1. 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 parts of the upper frame 51 and the vertical frame 52 that are in a position overlapping with the upper frame engagement piece 14 (see FIG. 4). This allows the worker to fasten all the screw fastening parts with the upper frame 51 and the vertical frame 52 positioned in the assembly jig main body 1. The worker can also fasten all the screw fastening parts with the upper frame 51 and the vertical frame 53 positioned in the assembly jig main body (not shown).

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

[0042] In this way, by using the assembly jig for the elevator jamb in accordance with the first embodiment, it is possible to easily position the top frame 51 and the vertical frame 52, and the top frame 51 and the vertical frame 53 when assembling the elevator jamb 50. This makes it possible to improve the workability of assembling the elevator jamb 50.

[0043] Also, because the assembly jig main body 1 of the elevator jamb assembly jig according to the first embodiment engages with the corners of the elevator jamb 50, it can be made smaller. Therefore, the elevator jamb assembly jig according to the first embodiment can be made compact and easy to carry. Furthermore, the elevator jamb assembly jig can reduce the space required for transportation, allowing for reduced transportation costs.

[0044] The elevator jamb assembly jig according to the first embodiment may include a spacer that is interposed between the vertical frames 52, 53 and a flat surface such as a floor. The height of this spacer is set to the same height as the base portion 11 of the assembly jig main body 1. This allows the vertical frames 52, 53 to be in a position parallel to the flat surface such as a floor, further improving workability. In order to reduce the size of the spacers, it is preferable to provide a spacer for each of the vertical frames 52, 53.

[0045] 2. Second embodiment [Configuration of elevator frame assembly jig] Next, the configuration of an assembly jig for an elevator jamb according to a second embodiment of the present invention will be described with reference to FIG. Fig. 6 is a perspective view of an assembly jig body for an elevator jamb according to the second embodiment. In Fig. 6, the same reference numerals are used to designate the same components as those in the first embodiment.

[0046] The assembly jig for an elevator jamb according to the second embodiment includes an assembly jig main body 3 which positions the upper frame 51 and the vertical frame 52, an assembly jig main body (not shown) which positions the upper frame 51 and the vertical frame 53, and an angle adjustment member 2 (see FIG. 3). The assembly jig main body which positions the upper frame 51 and the vertical frame 53 according to the second embodiment is formed symmetrically to the assembly jig main body 3. Here, the configuration of the assembly jig main body 3 will be described, and descriptions of the assembly jig main body and angle adjustment member 2 which position the upper frame 51 and the vertical frame 53 according to the second embodiment will be omitted.

[0047] 6, the assembly jig body 3 includes a base portion 31, a corner outer surface engaging portion 32, and a corner inner surface engaging portion 13. The corner inner surface engaging portion 13 is the same as that 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 a substantially rectangular plate shape. 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 flat surface of the base portion 31 is an abutment surface 31e. One end surface in the depth direction of the upper frame 51 and the vertical frame 52 abuts against the abutment surface 31e. The other flat surface of the base portion 31 abuts against a flat surface such as a floor at the installation site of the elevator jamb 50.

[0049] An opening 37 is formed in the base portion 31. The opening 37 is formed in a rectangular shape having a size that reaches 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 a corner of the elevator jamb 50 formed by the upper frame 51 and the vertical frame 52.

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

[0051] The corner outer surface 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 extending 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 that is substantially perpendicular to the abutment surface 31e of the base portion 31 and the upper frame engagement surface 14a of the upper frame engagement piece 14, and faces the corner inner surface 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 FIG. 1).

[0052] An opening 38 is formed in the vertical frame engaging piece 35. The opening 38 is located at a portion facing the opening 37 in the thickness direction of the base portion 31. The opening 38 communicates 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 at the corner portion of the elevator jamb 50 formed by the upper frame 51 and the vertical frame 52.

[0053] The elevator jam assembly jig according to the second embodiment, like the elevator jam assembly jig according to the first embodiment, can improve the workability of the assembly work of the elevator jam 50. Furthermore, the assembly jig main body 3 of the elevator jam assembly jig according to the second embodiment can be made smaller because it engages with the corners of the elevator jam 50. Therefore, the elevator jam assembly jig according to the second embodiment can be made compact and easy to carry. Furthermore, the space required for transporting the elevator jam assembly jig can be made smaller, allowing for a reduction in transportation costs.

[0054] Moreover, the assembly jig main body 3 according to the second embodiment has an opening 37 formed in the base portion 31. This allows the worker to insert his or her finger into the opening 37 and touch one end face in the depth direction at the corner of the elevator jamb 50. As a result, it is possible to confirm that there is no step 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 main body 3 according to the second embodiment can improve the assembly accuracy of the elevator jamb 50.

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

[0056] 3. Summary (1) As described above, the elevator jamb assembly jig according to the first embodiment is used when assembling the elevator jamb 50 by connecting the upper frame 51 and a pair of vertical frames 52, 53 in a generally U-shape. The elevator jamb assembly jig includes an abutment surface 11e against which one end face in the depth direction of the upper frame 51 and the vertical frame 52 (53) abuts, and a corner outer surface engagement portion 12 and a corner inner surface engagement portion 13 protruding from the abutment surface 11e. The corner outer surface engagement portion 12 engages with the outer surface of the corner formed by the upper frame 51 and the vertical frame 52 (53). The corner inner surface engagement portion 13 engages with the inner surface of the corner formed by the upper frame 51 and the vertical frame 52 (53). This allows the positioning of the upper frame 51 and the vertical frames 52 (53) to be easily performed, improving the workability of assembling the elevator jamb 50. Also, the elevator jamb assembly jig can be made smaller, compact and easy to carry. Furthermore, the elevator jamb assembly jig requires less space for transportation, reducing transportation costs.

[0057] (2) Furthermore, the corner outer surface engaging portion 12 and the corner inner surface engaging portion 13 according to the first embodiment described above enable the upper frame 51 and the vertical frame 52 (53) to stand independently with one end surface in the depth direction facing downward. This allows the worker to perform the connecting work from a position where the connecting portion between the upper frame 51 and the vertical frame 52 (53) is easily visible.

[0058] (3) Furthermore, the corner outer surface engaging portion 12 according to the above-described first embodiment 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 positioning the upper frame 51 and the vertical frame 52 (53).

[0059] (4) Furthermore, the corner inner surface engaging portion 13 according to the first embodiment described above has a vertical frame engaging surface 13b that faces the vertical frame 52. The vertical frame engaging surface 13b is an inclined surface that inclines so as to increase the distance between it and the corner outer surface engaging portion 12 the further it moves away from the abutment surface 11e. The elevator jamb assembly jig according to the first embodiment includes an angle adjustment member 2 that engages with the vertical frame engaging surface 13b and the inner surface 52b of the vertical frame 52. As a result, an engagement surface can be formed using the angle adjustment member 2 in accordance with the inclination of the inner surface 52b of the vertical frame 52. Therefore, the assembly jig for the elevator jamb in accordance with the first embodiment can be used when assembling various elevator jambs having different inclination angles of the inner surface 52b of the vertical frame 52 in accordance with the specifications of the elevator landing entrance / exit.

[0060] (5) Furthermore, the assembly jig for the elevator jamb according to the first embodiment described above includes a base portion 11 that forms the abutment surface 11e. The base portion 11 is formed in a plate shape with one flat surface serving as the abutment surface 11e. This allows the elevator jamb assembly jig (assembly jig body) to be placed on a flat surface such as a floor, and the upper frame 51 and vertical frame 52 (53) to be positioned.

[0061] (6) Furthermore, the base portion 31 of 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 no step occurs between the upper frame 51 and the vertical frame 52 (53) at one end face in the depth direction. Therefore, the assembly jig for the elevator jamb in accordance with the second embodiment can improve the assembly precision of the elevator jamb 50.

[0062] (7) Furthermore, the corner outer surface engagement portion 32 of 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 check that there is no step between the upper frame 51 and the vertical frame 52 (53) on the outer surfaces of the corner portion (so-called surface alignment). Therefore, the assembly jig for the elevator jamb in accordance with the second embodiment can improve the assembly precision of the elevator jamb 50.

[0063] The above describes the embodiment of the elevator jamb assembly jig, including its operation and effect. However, the elevator jamb assembly jig of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the invention as set forth in the claims.

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

[0065] In this specification, the words "parallel" and "orthogonal" are used, but these do not mean only "parallel" and "orthogonal" in the strict sense, but may also mean a "substantially parallel" or "substantially orthogonal" state that includes "parallel" and "orthogonal" and is within a range in which the respective functions can be exerted.
