A switchgear for retrofitting that is attached to a building corresponding to a shutter unit including a shutter frame and a door pocket has been proposed (for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2014-77243

The switchgear described in Patent Document 1 can be installed relatively easily because it is not necessary to remove the existing shutter unit. However, in this switchgear, in order to support the weight of the opening / closing body even in the support frame on the door pocket side of the support frames supporting the opening / closing body, the support frame on the door pocket side is fixed to the existing shutter frame. However, when the existing shutter frame is distorted, it is necessary to adjust the fixing position of the support frame according to the strain, which is troublesome for construction.

The present invention has been made in view of these circumstances, and an object of the present invention is to provide a switchgear that can be constructed relatively easily.

In order to solve the above problems, the opening / closing device of an embodiment of the present invention is an opening / closing device provided corresponding to a shutter unit including a shutter frame and a door pocket, and is opened / closed for opening / closing the frame opening of the shutter frame. It includes a shutter unit including a body and a support frame fixed to a building so as to surround the shutter frame and supporting the shutter unit. The support frame includes a three-sided frame-shaped main body portion whose door pocket side is opened and fixed to the building, and a connecting frame connected to the open end of the main body portion.

Another aspect of the present invention is a construction method. This method is a construction method of a switchgear provided corresponding to a shutter unit including a shutter frame and a door pocket, and a three-sided frame-shaped main body having an open door pocket side is fixed to the building so as to surround the shutter frame. A step of fixing a shutter unit including an opening / closing body for opening / closing the frame opening of the shutter frame to the main body portion, and a step of connecting the connecting frame to the open end of the main body portion.

According to the present invention, it is possible to provide a switchgear that can be constructed relatively easily.

It is a perspective view of the opening and closing device which concerns on embodiment. It is a perspective view of the switchgear seen from the angle different from FIG. It is an exploded three-dimensional view of a switchgear. It is a front view of a switchgear. FIG. 4 is a cross-sectional view taken along the line AA of FIG. It is a process drawing which shows the method of constructing a switchgear in a building. It is a process drawing which shows the method of constructing a switchgear in a building.

Hereinafter, the same or equivalent components and members shown in the drawings shall be designated by the same reference numerals, and redundant description will be omitted as appropriate. In addition, the dimensions of the members in each drawing are shown enlarged or reduced as appropriate for easy understanding. In addition, some of the members that are not important for explaining the embodiment in each drawing are omitted and displayed.

In the conventional switchgear for retrofitting that is attached to the building corresponding to the shutter unit, the support frame on the door pocket side of the support frames that support the switchgear also supports the weight of the switchgear, so it is used in the existing shutter frame. The support frame on the door pocket side is fixed. In this case, if the shutter frame is distorted, the fixed position of the support frame must be adjusted according to the strain. Further, for example, when fixing with screws, a hole is made in the shutter frame, so that it is necessary to separately perform waterproofing. Therefore, construction becomes difficult. From the above circumstances, the inventor has come to obtain a switchgear and a construction method thereof according to the embodiment. Hereinafter, a specific description will be given.

(Switchgear)
FIG. 1 is a perspective view of the switchgear 10 according to the embodiment. In FIG. 1, the shutter curtain 32 is shown semi-transparently. FIG. 2 is a perspective view of the switchgear 10 viewed from an angle different from that of FIG. FIG. 2 shows a state in which a part of the case 30 and the shutter curtain 32 are removed. FIG. 3 is an exploded perspective view of the switchgear 10. FIG. 4 is a front view of the switchgear 10. FIG. 5 is a cross-sectional view taken along the line AA of FIG.

Hereinafter, the substantially horizontal direction parallel to the outer wall surface of the building to which the switchgear 10 is attached (the outer wall surface that is flat as a whole) is referred to as the "finding direction", and the substantially horizontal direction orthogonal to the finding direction is defined as "the finding direction". It will be explained as "probable direction". Further, the side away from the building to which the switchgear 10 is attached in the prospective direction will be described as the "front side".

The opening / closing device 10 is provided corresponding to the existing shutter unit 102, and the shutter unit 102 is provided corresponding to the window portion. The window portion includes a window frame 110 attached to the outer wall so as to surround the opening of the outer wall of the building, and a glass door (not shown) fitted in the window frame 110. The shutter unit 102 includes a shutter frame 104 and a door pocket 106 for storing a shutter (not shown) that fits in the shutter frame 104.

The shutter frame 104 is a three-sided frame, and includes an upper frame 104a, a lower frame 104b, and a vertical frame 104c. The upper frame 104a and the lower frame 104b extend in the finding direction. The vertical frame 104c extends in the vertical direction and connects the ends of the upper frame 104a and the lower frame 104b on the opposite side of the door pocket 106. The upper frame 104a, the lower frame 104b, and the vertical frame 104c are formed integrally with the window frame 110 on the front side of the window frame 110, for example, extending from the window frame 110 to the front side.

As a remodeling of the shutter unit 102, the opening / closing device 10 is basically mounted on the shutter unit 102 with the shutter unit 102 as it is. In the present embodiment, the opening / closing device 10 is a shutter device including a shutter curtain (described later) as an opening / closing body. The switchgear 10 includes a support frame 12, a shutter unit 14, and a light-shielding member 16.

The support frame 12 is fixed to the building by fixing means such as screws so as to surround the shutter frame 104, that is, to surround the upper frame 104a, the lower frame 104b, and the vertical frame 104c. The support frame 12 may be fixed to a pillar portion (not shown) of the building via an outer wall, for example. Further, the support frame 12 is fixed to the building so that the weight of the shutter frame 104 and the door pocket 106 is not applied. Specifically, the support frame 12 is fixed to the building without being fixed to the shutter frame 104 and the door pocket 106.

The support frame 12 includes a main body portion 20 and a connecting frame 50. The main body 20 is a three-sided frame-shaped member with the door pocket 106 side open, and includes a main body upper frame 22, a main body lower frame 24, and a main body vertical frame 26. The main body upper frame 22 is fixed to the building above the shutter frame 104 so as to extend in the finding direction. The lower frame 24 of the main body is fixed to the building below the shutter frame 104 so as to extend in the finding direction. The width of the lower frame 24 of the main body in the prospective direction is larger than that of the shutter frame 104, and protrudes forward of the shutter frame 104 (see FIG. 5). The main body vertical frame 26 is fixed to the building on the side opposite to the door pocket 106 with respect to the shutter frame 104 in the finding direction so as to extend in the vertical direction. The main body vertical frame 26 connects the ends of the main body upper frame 22 and the main body lower frame 24 on the opposite side of the door pocket 106.

The connecting frame 50 is connected to the open end of the three-sided frame-shaped main body 20 so as to extend in the vertical direction. The connecting frame 50, together with the main body vertical frame 26, guides the vertical movement of the shutter curtain 32 when the shutter curtain 32 is opened and closed by the rail 50a (see FIG. 2) formed on the main body vertical frame 26 side. The lower end of the connecting frame 50 is placed on the lower frame 24 of the main body and is locked to the lower frame 24 of the main body by a locking mechanism (not shown). The lower end of the connecting frame 50 is particularly the end of the main body lower frame 24 on the door pocket 106 side, and is mounted on the front end of the main body lower frame 24 protruding forward from the shutter frame 104, and is mounted on the main body lower frame 24. It is locked. The upper end of the connecting frame 50 enters the case 30 (described later) located in front of the main body upper frame 22 from below. The upper end of the connecting frame 50 is locked by the locking projection 30a of the case 30 to restrict movement in the finding direction and the prospective direction (see FIG. 2). It should be noted that the locking projection 30a only restricts the movement of the connecting frame 50 in the finding direction and the prospective direction, and the weight of the locking projection 30a and thus the case 30 is not applied to the connecting frame 50. Further, the connecting frame 50 is designed so that the weight of other members is not applied. That is, the connecting frame 50 is connected to the open end of the main body 20 without supporting the weights of the main body 20 and the shutter unit 14.

Further, the connecting frame 50 is formed so that the dimensions in the finding direction are smaller than those of the main body upper frame 22, the main body lower frame 24, and the main body vertical frame 26. In particular, the connecting frame 50 is formed so that the portion of the main body lower frame 24 projecting forward from the shutter frame 104 and the size in the finding direction are smaller than those of the case 30. As a result, the connecting frame 50 is located in front of the window frame 110 and the shutter frame 104, and floats from the outer wall of the building, the window frame 110, and the shutter frame 104.

In the present embodiment, a mullion for continuous windows, which is a member for partitioning the window frame to the left and right in the conventional sash window, is adopted as the connecting frame 50.

The shutter unit 14 includes a case 30, a shutter curtain 32, and a shaft 34. The case 30 is a long box-shaped member, and is fixed to the main body upper frame 22 so that the longitudinal direction substantially coincides with the finding direction. The case 30 houses the shafts 34 and hides them.

The shaft 34 is rotatably supported. The shutter curtain 32 is an opening / closing body for opening / closing the frame opening 18 of the support frame 12 and thus the frame opening 108 of the shutter frame 104, and one end thereof is fixed to the shaft 34. Therefore, the shutter curtain 32 is supported by the main body upper frame 22 and thus the support frame 12 via the shaft 34 and the case 30.

The light-shielding member 16 is provided so as to block at least a part of the light that is about to enter the building through the gap between the support frame 12 and the door pocket 106 (see FIGS. 1 and 5). The light-shielding member 16 is an elastic body such as rubber or sponge. The light-shielding member 16 is fixed to the side surface 50a of the connecting frame 50 on the door pocket 106 side, and is sandwiched between the connecting frame 50 and the end plate 106a of the door pocket 106.
