安価に製作されるものでなければならない。 In this case, the use of crossbeams on the front and back sides of the framework for assembling the rocker for the opening and closing doors provided on the front and back is not allowed, and special consideration is required from the viewpoint of strength. In particular, when the height of the rocker is made larger than the installation area in order to economize on the installation area, strict consideration is required in the framework design. In addition, it must be lightweight, have a small number of parts, be easy to assemble, and be manufactured at low cost.

にかゝることはない。 A top frame 13 and a bottom frame 14 of a rectangle-shaped frame are welded to the top and bottom of the frame frame which are all welded together in this way, and in the illustrated example, a cover plate 15 is further attached to the top frame 13, and the bottom frame 14 is configured to be fixed on a pedestal 16. Back doors (not shown), which have approximately the same shape as the front door 17, are attached to the main frames 1 and 2 so that they can be opened and closed, respectively, by a hinge mechanism or the like, but the weight of the electronic equipment panel fixed to the mounting hole 9 is applied to both opening and closing doors. It doesn't bother me.

以上の従来のロツカー構成では所要の部品点数
が比較的に多く、その上総ての結合が熔接によつ

Vertical side edges 23, 24, 23', and 24' provided on the top and bottom of the side plate 18 on both the front and back sides are further provided with vertical protrusions 26 at both ends, and an overhanging side 25 bent inward in an L-shape. A top frame 21 and a bottom frame 22 of the same shape are provided with
The protruding portion 26 is pushed into the space 27 between the side edges 19 and 20 formed at the left and right ends of the side plate 18,
This is achieved by means of rockers configured according to the present invention, which are screwed together at the mounting holes.

を可能にした。 In other words, the most distinctive feature of the structure of the present invention is that the role of the support for the main frame of the conventional structure is played by the sides that are bent in a Z-shape on both the long left and right sides of the side panels to increase strength. The upper and lower crossbeams of the main frame are constructed using the same-shaped top and bottom frames, which have vertical sides on both the front and back sides and overhanging sides that are bent inward in an L-shape to increase strength. Before and after 2 by having a role
This eliminates the need for separate main frames, eliminates all welding work, and performs all screwing work, making it possible to significantly reduce production costs.

される。 Although the above configuration is sufficient for accommodating the number of electronic device panels conventionally used, in order to increase the accommodating density, it is necessary to install horizontally on both sides between the top frame 21, bottom frame 22 and side plate 18. a bent side 29;
This purpose is achieved by using a reinforcing frame 28 having an L-shaped cross section with vertically bent sides 30.

置で互いに螺締結合される。 Figure 2a shows an embodiment of the present invention in an exploded perspective view for ease of understanding, similar to Figure 1.
The left and right side plates 18 have short horizontal sides 19 on both upper and lower sides.
is made in a shape with long side sides 20 bent in a Z-shape on both the left and right sides, while a top frame 21 and a bottom frame 22 of the same shape have vertical sides 23 provided on both the front and rear sides. 23' and 24, 24' are further provided with overhanging sides 25, 25' which are bent inward in an L-shape, and are shown in Figures b (perspective view) and c.
As shown in the enlarged view (top view), the vertical sides 23,
The protrusions 26 of 23' and 24, 24' are pushed into 27 between the sides 19 and 20 formed at the left and right ends of the side plate 18, and screwed into each other at the mounting holes (indicated by circles). It is concluded.

It is used by being sandwiched between the side plate 18 and the side 23 of the top frame 21 and the side 24 of the bottom frame 22, and the horizontally bent side 29 is connected to the side 19 of the side plate 18. The vertically bent side edge 30 is connected to the Z side of the side plate 18 as shown in FIG.
It is screwed together with the central side portion 31 of the bent portion.

(f) 考案の効果 以上説明のように本考案のロツカーにあつては
