In the following description, the outdoor side of the switchgear 1 will be referred to as the front surface, and the indoor side will be referred to as the rear surface. Further, in the installation state of the opening/closing device 1, the upper side is referred to as the top, the lower side is referred to as the bottom or the bottom, and the longitudinal direction of the panel body is sometimes referred to as the width direction.
The upper panel body 11A includes a front surface member 11A1 having a flat front surface without ribs, and a flat surface for maintaining the flatness of the front surface. It comprises a holding member 11A3, and a rear surface member 11A2 that constitutes the indoor rear surface of the panel body and is provided with the flat surface holding member 11A3.
The upper panel body 11A is the panel body located on the uppermost side of the opening/closing body 11, and a first projecting member 181 is provided on the top thereof. The first convex member 181 will be described later.

3A and 3B are diagrams showing the front member 11A1 of the present embodiment, FIG. 3A is a side view, and FIG. ).
The front member 11A1 is formed by bending a plate of carbon steel (so-called steel or steel) or stainless steel (hereinafter referred to as "steel material") having a thickness of 0.8 mm or more.
The upper end side of the front member 11A1 is bent substantially perpendicularly from the front surface 11A11 to the rear side to form an upper surface 11A15, and is bent downward from the upper surface 11A15 substantially perpendicularly to form an upper folded portion 11A16. As shown in FIG. 3(b), a hole 11A1H2 for attaching a member connecting the trolley arm 144 is formed near the center of the upper folded portion 11A16 in the width direction.
On the lower end side of the front surface member 11A1, a corrugated convex portion 11A13 and a corrugated concave portion 11A14 are formed by bending a steel plate. The piercing convex portion 11A13 and the piercing recessed portion 11A14 form a piercing structure together with the upper end portion of the intermediate panel body, which will be described later. A lower folded portion is formed by bending the rear side of the recessed portion 11A14 upward at a substantially right angle, and a hinge connecting portion 11A12 for connecting a hinge member is formed at the lower folded portion. With the above configuration, the hinge connecting portion 11A12 is formed at a position offset indoors by a predetermined distance from the front surface 11A11.
Two holes 11A1H1 (long holes) for inserting fastening members (nut rivets) PN are formed in each of the hinge connection portions 11A12 (a set of two holes constitutes one hinge connection portion). As shown in FIG. 3B, a plurality of hinge connection portions 11A12 are provided at predetermined intervals in the width direction of the front member 11A1 (five locations in this embodiment. connected). The hole 11A1H1, which is an elongated hole, is formed such that its long axis extends in the vertical direction.
A notch 11A17 is formed between the hinge connection portions 11A12 in the lower folded portion (surface on which the hinge connection portions are formed) on which the hinge connection portions 11A12 are formed. In other words, "notches are formed in the longitudinal direction of the panel body at locations other than the hinge connecting portions". The notch helps reduce the weight of the panel body. For the same purpose of weight reduction, a notch may be formed in the upper folded portion 11A16.

4A and 4B show a rear surface member 11A2 and a flat surface holding member 11A3. FIG. 4A is a side view, and FIG. 4B is a rear view. Figure omitted).
The flat surface holding member 11A3 is a member joined to the front surface 11A11 in order to maintain the flatness of the front surface 11A11.
The rear member 11A2 constitutes a hollow panel body by being joined to the front member 11A1.
In this embodiment, the rear surface member 11A2 and the flat surface holding member 11A3 are integrally formed (extruded) from an aluminum alloy.

The flat surface holding member 11A3 is formed to extend from the rear surface member 11A2 toward the front surface side, and has a flat portion formed parallel to the front surface 11A11 by bending at a substantially right angle at the tip portion thereof. The flat portion at the tip is joined to the indoor side of the front surface 11A11 (see FIG. 2(a)). In this embodiment, two flat holding members 11A3 are formed, the upper flat holding member 11A3 is glued to the front face 11A11 and then joined by riveting, and the lower flat holding member 11A3 is glued to the front face 11A11. joined by Although riveting or adhesion is used as an example here (any method of either adhesion or riveting or a combination of both may be used), the required strength can be obtained by joining the planarity holding member 11A3 and the front surface 11A11. Any joining method may be used.
In the present embodiment, two flat surface holding members 11A3 are formed as an example, but one or three or more may be formed.
In addition, the flat surface holding members 11A3 in this embodiment are formed over substantially the entire width direction of the panel body, but the present invention is not limited to this. It may be something that can be used.

The rear surface member 11A2 is a member configured to connect the upper portion and the lower portion of the front surface member 11A1, thereby forming a hollow panel body.
As shown in FIG. 4(a), the rear surface member 11A2 is basically a flat plate-like member, and has an upper surface bent at a substantially right angle toward the front side at its upper end. As shown in FIG. 2A, the upper surface portion abuts on the outer side of the upper portion of the front member 11A1, and also functions as a positioning member when the rear member 11A2 is assembled to the front member 11A1. . In other words, the front member 11A1 can be positioned by hooking the upper surface of the rear member 11A2, which improves workability.
As shown in FIG. 4(b), holes 11A2H3 for inserting fastening members (nut rivets) PN for mounting roller mounting members 11A4 (see FIG. 13) are formed at both ends of the rear surface member 11A2 in the width direction. It is In this embodiment, as will be described later, the hinge member has a structure in which the roller is held, but since the upper panel body has the hinge member only on the lower end side, the roller attachment member, which is a separate member for attaching the roller 11A4 is used. As shown in FIGS. 4A and 4B, a recess 11A25 is formed at the position where the hole 11A2H3 is formed. The concave portion 11A25 is a relief portion for preventing the head portion of the nut rivet PN from projecting.
A hole 11A2H2 is formed in substantially the center of the upper end side of the rear surface member 11A2 so as to communicate with the hole 11A1H2 of the front surface member 11A1.
A hole 11A2H1 is formed on the lower end side of the rear member 11A2 so as to face the hinge connecting portion 11A12 of the front member 11A1 and communicate with the hole 11A1H1 of the front member 11A1. The hole 11A2H1, which is an elongated hole, is formed so that its long axis is in the width direction, and therefore is formed so that its long axis is substantially orthogonal to the hole 11A1H1 of the front member 11A1.
A recess 11A22 is formed at the position where the hole 11A2H1 is formed. The concave portion 11A22 is a relief portion for preventing the head portion of the nut rivet PN from projecting. A convex portion 11A24 having substantially the same height as the depth of the concave portion 11A22 is formed on the front side near the lower end of the rear surface member 11A2. The convex portion 11A24 is in contact with the front surface member 11A1 together with the front side of the concave portion 11A22 (see FIG. 2(a)), and functions as a leg portion that supports the load received from the hinge member.
A protruding portion 11A21 protruding toward the indoor side is formed at the upper portion of the vicinity of the recessed portion 11A22 and adjacent thereto when the hinge member is attached. As will be described later, the projecting portion 11A21 has a curved surface directed toward the portion of the hinge member that protrudes most toward the indoor side on the inclined surface toward the vertex.
The protrusion 11A21 is also provided near the upper end of the rear surface member 11A2. These two protrusions 11A21 are provided across the width direction of the rear member 11A2, and serve as ground legs when the rear member 11A2 is placed with the back side of the rear member 11A2 facing down. As described above, the rear surface member 11A2 is formed by extrusion molding, but when a member having a shape like the rear surface member 11A2 is formed as an extruded material, the member tends to be drawn to the side where the flatness retaining member 11A3 is present. That is, in FIG. 4A, the upper end side and the lower end side tend to warp leftward. In order to suppress such a tendency, it is preferable to perform molding with the rear surface side of the rear surface member 11A2 facing downward. At this time, due to the presence of the two projections 11A21 that serve as grounding legs, the back surface of the rear surface member 11A2 is less likely to be scratched or the like when the back surface side of the rear surface member 11A2 is placed downward. be.

The attachment of the rear surface member 11A2, which is integrally formed with the flat surface holding member 11A3, to the front surface member 11A1 having the above-described configuration is performed by riveting the rear surface member 11A2 in contact with the upper folded portion of the front surface member 11A1 and fastening with the nut rivet PN. and the hole 11A2H1 of the rear surface member 11A2. Further, the upper flat surface holding member 11A3 and the front surface 11A11 are riveted, and the lower flat surface holding member 11A3 and the front surface 11A11 are bonded.
As a result, a hollow upper panel body 11A is constructed, and the front surface 11A11 is held therein by the planar holding member 11A3.
In attaching the rear surface member 11A2 to the front surface member 11A1, as described above, the upper surface of the rear surface member 11A2 can be hooked so as to position both members, resulting in excellent workability. Further, the holes 11A1H1 and 11A2H1 for inserting the fastening members (nut rivets PN) respectively formed in the front member 11A1 and the rear member 11A2 are provided so that the longitudinal directions of the long holes are substantially orthogonal. , the relative positions of the front member 11A1 and the rear member 11A2 can be adjusted up, down, left and right by the clearance generated by the elongated holes. Since the rear surface member 11A2 is made of an extruded material, it can be formed with high accuracy, but the front surface member 11A1 is formed by bending a steel plate, so it is difficult to obtain high accuracy. Errors between parts caused by this can be absorbed by the configuration of the holes 11A1H1 and 11A2H1. In addition, if the longitudinal directions of both elongated holes are substantially perpendicular to each other, the above effect is maximized, which is preferable. effect can be obtained. In this embodiment, the longitudinal direction of the elongated hole is the up-down direction on the front member 11A1 side and the width direction on the rear member 11A2 side, but the relationship may be reversed.

Since the lower end side of the front member 21C1 has the same configuration as the lower end side of the front member 11C1 of the lower panel body 11C of the first embodiment, description thereof will be omitted here.

The flat surface holding member 21C3 has the same concept as the flat surface holding member 21A3 of the upper panel body 21A and the flat surface holding member 21B3 of the intermediate panel body 21B, so the description thereof will be omitted here.

The rear surface member 21C2 is also formed by folding back a steel plate, and a lower end member 21C8 formed of an extruded aluminum material is attached as a separate member to the lower end side of the rear surface member 21C2.
Since the upper end side of the rear surface member 21C2 (see FIG. 42) has the same structure as the upper end side of the rear surface member 21B2 of the intermediate panel body 21B, description thereof will be omitted here.
A concave portion 21C25 extending along the longitudinal direction of the rear surface member 21C2 and opening to the indoor side is formed by bending a steel plate.
The concave portion 21C25 mainly functions as a hand portion for opening and closing the opening/closing body by hand when the lower panel body 21C is in the vertical state. A support member 21C4 (see FIG. 41(a)) that is provided between the upper surface and the lower surface of the recess and supports the load in the vertical direction is attached to a position substantially in the center of the width direction of the recess 21C25. The support member 21C4 is also a support member that is attached to the upper and lower sides of the recess 21C25 across the recess 21C25 and supports the load in the vertical direction.
The structure of the lower end member 21C8 attached to the lower end side of the rear surface member 21C2 is the same as that of the lower end side of the rear surface member 11C2 of the lower panel body 11C of the first embodiment. A bearing portion 21C27, which is a concave portion for receiving the roller shaft, and a handle portion 21C26 projecting upward from the lower surface side of the concave portion 21C25 are formed.

The panel bodies described above are connected to each other by hinge members 15 so as to be rotatable, thereby forming an opening/closing body. The configuration of the hinge members 15 (and the configuration in which the rollers Wh are supported by the hinge members 15 at both ends) and the connection method thereof are the same as those in the first embodiment, and therefore descriptions thereof will be omitted here.
It goes without saying that the opening/closing body of the present embodiment may also be provided with the handle structure for the release key described in the first embodiment.

As described above, the opening/closing device of the present embodiment is an example in which each panel body constituting the opening/closing body is entirely made of steel. can be obtained. In addition, in the opening/closing device of the present embodiment, since the rear surface members of each panel body are also made of steel, it is possible to obtain higher flame-shielding and fire-preventing performance.
In this embodiment, the front member of each panel body is made of a steel plate having a thickness of 0.8 mm or more. Flame shielding and fireproof performance can be obtained. You may make it form a front member and a rear member with a steel plate of 0.8 mm or more. That is, it is sufficient that "the front member and/or the rear member are formed of a steel material having a thickness of 0.8 mm or more".
Also, the front member and the rear member may be formed of a steel plate having a thickness of 0.5 mm or more. The flat holding member can be regarded as the frame of the panel body, and therefore the flat holding member made of steel corresponds to the "iron frame".

In the second embodiment, the flat surface holding member is formed separately from the rear surface member.
FIG. 43 shows an example of such (taking an intermediate panel body as an example).
The rear surface member 31B2 of the intermediate panel body 31B shown in FIG. 43 is formed by bending a steel plate to form a flat holding member 31B3 as a concave portion that is recessed toward the front surface member 31B1 and substantially abuts on the back side of the front surface. .
Although the intermediate panel body is used as an example here, it is of course possible to apply the same to the upper panel body and the lower panel body. In the lower panel body, the depression for the hand may be made to have a depth that substantially abuts on the back side of the front surface, so that it also functions as a flat surface retaining member.
The point that the flat surface holding member 31B3 may be adhered to the front surface member 31B1 is the same as in each embodiment. or support members attached to the upper and lower sides of the recess across the recess to support the load in the vertical direction.

Each panel constituting the opening/closing body of each embodiment has a constant thickness and is connected by a hinge member on the back side (the hinge axis is on the back side). When the body rotates, a gap is generated on the front side at the joint portion (interlocking structure portion) of each panel body. The rotation of the panel only occurs near the top of the opening where the curved rail connects the vertical and horizontal rails. However, FIG. 44 shows an example of a structure that reduces the risk of fingers being jammed in the above-described gap.
