Abstract

PROBLEM TO BE SOLVED: To save the space for installing a cabinet by removing protrusions without removing angles one by one even when it is used for a deck top apparatus. SOLUTION: One side piece 2a of an L-shaped angle 2 is fixed to a side wall 1a, 1b of the electric apparatus cabinet 1 and the other side piece 2b of the angle 2 is fixed to a rack 3. The one and the other side pieces 2a, 2b of the angle 2 are connected through a rotary mechanism 4 having a shaft 4a. The mechanism 4 alternately winds the inner ends of both side pieces 2a, 2b to allow e.g. the other side piece 2b to turn, relative to the one side piece 2a. Further, the shaft 4a tightly winds up the wound parts 2c, 2d of the one and the other side pieces 2a, 2b at two positions 2e mutually distance in the axial direction of the shaft, thereby exerting an elastic force by the torsional action in the direction of superposing the other side piece 2b on the one side piece 2a.

[0003]

However, the conventional desk and rack-mounted dual-use electrical equipment housing apparatus has an angle a formed in an L-shape, and has one side piece b and the other side piece c. Is formed integrally, so that it is good when housed in a rack housing via a rack e as shown in FIG. 9, but when the electric appliance housing housing d is used on a desktop. , L-shaped angle a to rack e
In a state where the cable is removed, the other side piece c becomes a protrusion of the electric equipment housing d, which requires an extra installation space. It is necessary to remove it from the housing d.

In view of the foregoing, the present invention has been made in consideration of the above circumstances, so that even when used as a tabletop, even if the angle is not removed one by one, it cannot become a projection and can be used for both a tabletop and rack mounted electric machine. It is an object of the present invention to provide an apparatus housing device.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a method of mounting one side of an L-shaped angle on a side wall of an electric equipment housing and mounting the other side of the L-shaped angle on a rack. A desktop and rack-mounted dual-use electrical equipment housing device configured to be attached to an L-shaped angle, wherein one side piece and the other side piece of an L-shaped angle are connected via a rotation mechanism. .

According to the present invention, when the housing for accommodating electric equipment is used as a table, the L-shaped angle is folded and polymerized by being rotated by one side piece and the other side piece by a rotating mechanism. In this case, the angle cannot be a protrusion of the electrical device housing, and as a result, space can be saved.

Further, the rotating mechanism according to the present invention is characterized in that it has a spring means for urging both side pieces in a direction in which they overlap each other.

According to the present invention, when the other side piece of the L-shaped angle is removed from the rack, it is automatically folded and fixed on one side and fixed. Can be omitted.

[0009] The rotation mechanism according to the present invention is characterized in that it has a spring means for urging both side pieces in a direction to open each other.

According to the present invention, the one-side piece and the other-side piece of the L-shaped angle are automatically opened so that the L-shaped angle can be easily attached to the electronic device housing or the rack.

Further, the present invention is characterized in that a projection for promoting electrical conduction between the L-shaped angle and the rack is provided on a surface of the other side piece of the L-shaped angle which is in contact with the rack side. is there.

According to the present invention, the conductivity between the L-shaped angle and the rack can be stabilized by the projection, and unnecessary radiation such as radio waves can be shielded.

Further, according to the present invention, a guide portion formed by bending the opposite side of the L-shaped angle to the opposite side with respect to the one side is provided, and the guide slides on the rack. The other side piece can be opened relative to the one side piece.

According to the present invention, in a state in which one side piece of the L-shaped angle is attached only to the housing for the electric equipment, the other side piece is in a state of being overlapped and bent into one side piece, Therefore, when the other side piece is mounted on the rack side, it is necessary to open the other side piece with respect to the one side piece. By moving, the other side piece automatically performs the opening operation with respect to the one side piece, so that the opening operation of the other side piece is not required at the time of mounting on the rack.
