The mounting process of the rear plate (4) will be described. First,
As shown in FIGS. 2 and 3, the left and right connecting members (5), which are shown separately from the rear plate (4), are attached to the rear plate (4). As shown in FIG. 4, the hook portion (11) of the connecting member (5) is turned downward, and the rear side piece (7c) of the rear plate (4) is moved downward as indicated by an arrow. From. Then
As shown in FIG. 5, when the coupling member (5) is rotated forward, the outer surface of the hook portion (11) in a quarter-arc shape slides while abutting on the front surface of the rear plate (4), and the rearward facing piece is formed. As shown in FIG. 6 (c), the front end face of the hook (11) is fitted into the groove (8) of the rear face plate (4).
The positional relationship shown in FIG.

In this state, the connecting member (5) is
It is slidable in the left and right directions in the groove (8) of (4). Therefore, as shown by the arrow in FIG.
When (5) is moved to the left and right ends, the rectangular lateral protrusion (16) fits into the square hole (9) of the side flange (6) and projects laterally. At this time, the small projection (19) (FIG. 9) formed on the front end face of the hook (11) engages with the small hole (20) formed in the bottom of the groove (8). In this way, the coupling member (5) is positioned on the rear plate (4).

Next, as shown in FIG. 8, the connecting member (5)
The back plate (4) with the attached top plate holder (1) from below
Insert between (1). This operation is actually performed on the desk (A) placed upside down on the floor.

The upward protrusion (13) of the tip of the coupling member (5) is
At the same time as being inserted into the hole (21) formed in the lower surface of the top plate (2) (see FIGS. 9 and 10), the outer surfaces of the left and right connecting members (5) are connected to the side plate (1) of the top plate support (1). When inserted between 1a) and (1a), the lateral projection (16) is formed with cuts (1
7) Elastic bending and retraction due to the presence of the square hole in the side plate (1a)
When it reaches a position matching (14), it elastically jumps out into this square hole (14) and engages. This state is shown in FIG.

At this time, the notch (18) of the connecting member (5) is formed by the screw hole (10) of the side plate (6) of the rear plate (4) and the screw hole (10) of the side plate (1a) of the top plate support (1). As shown in FIG. 10, a tapping screw (22) is screwed in from here and the connecting member (5) is positioned at the aligned position, as shown in FIG.
Securely.

In the above-described embodiment, the connecting members (5) are provided only at the left and right ends of the rear plate (4). However, in some cases, similar connecting members may be provided at the intermediate portion. Also,
Although the top plate support 1 is shown as a sleeve box, one or both may be side legs.

[0025]

According to the first aspect of the present invention, the assembled positional relationship of the top plate, the rear plate, and the top plate support (the distance between the rear portion of the top plate and the rear plate, the rear plate and the top plate support, The upper surface of the top plate, etc.) can always be dimensionally constant, so the top surface of the top plate, the wiring cover, and the top plate rear member have excellent flatness,
Not only is it aesthetically pleasing, but the width of the wiring space where the wiring cover is attached becomes constant, so that it can be smoothly attached and detached.

According to the second aspect of the present invention, since the connecting member is attached to the rear face plate by the hook portion, the attaching operation can be easily performed.

According to the third aspect of the present invention, since the mounting of the hook portion is performed by the rotational movement guided by the front surface of the rear plate, the mounting operation can be performed easily and smoothly.

According to the fourth aspect of the present invention, the positioning of the hook portion at the rear plate end can be reliably performed.

According to the fifth aspect of the invention, angular positioning of the connecting member with respect to the rear plate and the top plate support can be reduced with play or looseness.

According to the sixth aspect of the present invention, the attachment of the connecting member to the proper position of the top support is facilitated by a simple operation of sliding the connecting member on the side plate of the top support to find the position. Can be done.

According to the seventh aspect of the invention, the final fixed mounting at the positioned regular position is performed.
