BACKGROUND OF THE INVENTION
The present invention relates to a structure for embedding in a wall a connection box in which a plurality of boxes for storing control equipment, security equipment, and the like are connected, and for attaching a frame to the connection box.
[0002]
[Prior art]
FIG. 6 shows an example of a conventional frame frame mounting structure to a box. As shown in FIG. 6A, a box 1 ′ such as a control device or a security device is embedded in a wall opening, and the box 1 ′ After the frame 2 'is fixed to the box 1' with screws 3 to close the gap between the peripheral edge and the wall opening, the front panel 4 'is attached to the frame 2' as shown in FIG. Yes. In this case, there is no problem if there is only one box 1 ′. However, as shown in FIG. 5C, in the case of a connection box in which the sub-box 1 ′ is connected to the main box 1 by screws 5 in the horizontal direction. Has the following problems:
[0003]
FIG. 7 shows a front view looking toward the wall surface. That is, as shown in FIG. 4A, the relative position and inclination of the frame frames 2 and 2 ′ when the frame frames 2 and 2 ′ are fixed to the connection boxes 1 and 1 ′, respectively. In this case, there is a problem in that the gap d is generated and the appearance design is deteriorated. Further, as shown in FIG. (B), a gap d remains when the front panels 4, 4 ′ are attached to the frame frames 2, 2 ′.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing one embodiment of a frame frame mounting structure to a connection box according to the present invention, as viewed from the front side. In addition, although this embodiment has shown the example which attaches a frame to the connection box which connected two boxes, you may apply to the connection box which connected three or more boxes. In the figure, the main frame frame 6 is fixed to the main box 1 described in FIG. 6C, and the sub frame frame 7 is fixed to the sub box 1 ′.
[0008]
The main frame frame 6 is folded so as to project a rectangular frame main body 9, a bowl-shaped vertical edge 10 integrally formed so as to project on both sides of the frame main body 9, and the frame main body 9. The panel support piece 11 is formed with a bend. At the four corners of the frame body 9, long holes 12 for fixing the box are formed in an oblique direction, screw head through holes 13 are formed at two upper and lower positions on the inner side surface of the vertical edge 10, and the upper panel support piece 11 is formed. An engaging slit 14 is formed, and a panel locking hole 15 is formed in the lower panel support piece 11.
[0009]
The sub-frame frame 7 includes a rectangular frame main body 9, a bowl-shaped vertical edge 10 integrally formed so as to protrude from one side portion of the frame main body 9, and upper and lower portions of the other side portion of the frame main body 9. The connecting piece 16 is bent so as to protrude, and the panel support piece 11 is formed so as to protrude above and below the frame body 9.
[0010]
In the four corners of the frame body 9, long holes 12 for fixing the box are formed in an oblique direction. Similarly to the main frame frame 6, screw insertion holes 13 are formed in the upper and lower portions on the vertical edge 10, and the upper and lower An engagement slit 14 is formed in the panel support piece 11, a panel locking hole 15 is formed continuously with the engagement slit 14, and a screw hole 17 is formed in the connection piece 16. The frame 7 has a vertically symmetrical shape.
[0011]
2A is a perspective view showing a state in which a part of the vertical edge 10 of FIG. 1 is broken, and FIG. 2B is a perspective view showing a state in which the main frame frame 6 and the sub-frame frame 7 are connected. FIG. 2C is a cross-sectional view showing the connection process. In addition, about the same structure as FIG. 1, the same number may be attached | subjected and description may be abbreviate | omitted.
In the vertical edge 10 of the main frame frame 6, side end portions of the frame main body 9 are bent and mounting pieces 19 are erected at two upper and lower portions, and screw through holes 20 are formed in the mounting pieces 19. (The same applies to the vertical edge 10 of the sub-frame frame 7).
[0012]
As shown in FIG. 2A, an abutment surface 19a is formed above the attachment piece 19 at the upper part of the main frame frame 6 at a right angle to the connection piece 16 of the sub-frame frame 7. The main frame frame 6 and the sub frame frame 7 are positioned by attaching the upper part to the abutting surface 19a.
[0013]
Next, a method for connecting the main frame frame 6 and the sub frame frame 7 will be described. As shown in FIG. 2, the connecting piece 16 of the sub-frame frame 7 is inserted into the vertical edge 10 of the main frame frame 6 and is brought into contact with the mounting piece 19 of the connecting piece 16 and the vertical edge 10. The main frame frame 6 and the sub-frame frame 7 are connected and unitized by inserting a screw 21 through the screw head through hole 13 and screwing it into the screw through hole 20 and the screw hole 17. The head of the screw 21 is accommodated in the vertical edge 10.
[0014]
The unit of the main frame frame 6 and the sub frame frame 7 connected as described above is provided with a long hole 12 for fixing the box in the main box 1, 1 ′ previously embedded in the wall described with reference to FIG. Secure with screws. At this time, the position adjustment of the frame frames 6 and 7 and the boxes 1 and 1 ′ can be easily performed by the long holes 12. When the frame frame is fixed, the front panel is attached to the main frame frame 6 and the sub-frame frame 7.
[0015]
FIG. 3A is a perspective view of the front panel as seen from the back side, and FIG. 3B is an exploded perspective view of the main part. The front panel 22 is formed in a box shape, and a pair of adjustment long holes 23 are formed on the upper surface thereof, and the engaging member 24 is fixed by an adjustment screw 25 through the adjustment long holes 23. The engaging member 24 is formed with an engaging piece 24a bent downward.
[0016]
FIG. 4A is a diagram illustrating a state in which the front panel 22 is attached to the sub-frame frame 7. The front panel 22 can be attached to the sub-frame frame 7 by engaging the engagement piece 24a of the front panel 22 with the engagement slit 14 of the upper panel support piece 11 of the sub-frame frame 7. A fixing screw 26 is provided on the lower surface of the front panel 22, and the lower part of the front panel 22 is fixed by locking the fixing screw 26 in the panel locking hole 15 of the lower panel support piece 11. The front panel 22 is similarly attached to the main frame frame 6.
[0017]
When the front panel 22 is attached, depending on the fixing position of the frame frame to the box, the size of the gap d between the frame frames 6 and 7 may be different on the left and right of the front panel 22 as shown in FIG. In that case, the engaging screw 24 is moved to the right in FIG. 3 by loosening the adjusting screw 25 and sliding the locking member 24 in FIG. The position can be adjusted.
[0018]
4B and 4C are views for explaining how to remove the front panel 22. In the figure, the upper part is a cross-sectional view of the upper surface panel, and the lower part is an overall perspective view. In the figure, 1 'indicates a sub-box and 7 indicates a sub-frame, but the same applies to the main frame 6 as well.
[0019]
First, as shown in FIG. 2B, the retaining screw 26 at the lower part of the front panel 22 is loosened, and the lower part of the front panel 22 is moved in the direction indicated by the arrow in the position where the tip of the retaining screw 26 is removed from the panel locking hole 15. After the rotation, as shown in FIG. 3C, when the front panel 22 is lifted, the engagement piece 24a is disengaged from the engagement slit 14 of the sub-frame frame 7, and the front panel 22 can be removed.
[0020]
Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made. For example, in the above embodiment, the frame frame mounting structure when the sub box 1 ′ is connected to the right side of the main box 1 is shown, but the left side of the main box (in this case, the sub frame frame 7 is turned upside down). It can also be applied when sub-boxes are connected on both sides, or when a plurality of sub-boxes are sequentially connected.
[0021]
