The step portions 75 and 75 are formed such that when the engagement fitting 7 is attached to the side plate 5, the attachment screws 741 and 741 are not obstructed when connected to the curtain plate 31, An attachment recess 51 and an attachment are provided at a location where the engagement fitting 7 of the side plate 5 is attached so that the movement of the head 64 of the headed engagement tool 6 is not hindered when the rear curtain plate 31 and the side plate 5 are connected. Mounting steps 52 and 52 are formed so that the screws 741 and 741 do not contact the rear curtain plate 31.
[0012]
A lower insertion hole 53 is formed at the rear lower end of the side plate 5 corresponding to the lower connection screw hole 34 of the lower shelf part 3, and the upper connection screw hole 28 of the top plate part 2 above the front end part. Corresponding to the upper insertion hole 54 is formed.
[0013]
The top plate 2 includes a rectangular top plate 21, left and right receiving plates 22, 22 disposed by mounting dowels and connecting brackets in the front-rear direction of the left and right end surfaces and the inner lower surface of the top plate 21, and left and right receiving plates. 22 and 22 between the center receiving member 23 disposed on the lower surface of the top plate 2 with mounting dowels and connecting fittings in the front-rear direction, and between the lower surfaces of the left and right receiving plates 22 and 22 and the central receiving member 23. Is supported by a rail member (not shown) disposed in the front-rear direction on both the left and right sides of the center receiving member 23 and the lower-surface reinforcing bar 24 that connects the left and right receiving-side plates 22, 22. The left and right drawers 25 and 25 are configured.
[0014]
Locking brackets 27, 27 having locking protrusions 26 projecting rearward corresponding to the locking holes 41 of the curtain plate 31, with a predetermined distance from the lower surface of the ceiling plate 21, It is attached with mounting screws to the bottom of the left and right ends of the end.
Further, upper connecting screw holes 28 and 28 are formed at the front end portions of the left and right receiving plates 22 and 22 of the drawers 25 and 25 so as to correspond to the upper connecting insertion holes 54 of the left and right side plates 5 and 5.
[0015]
The present invention is constructed as described above and is assembled as follows.
First, the engagement brackets 7 and 7 are attached in a state where the lower shelf portion 3 with the headed engagement tools 6... Screwed at predetermined positions on the left and right end surfaces of the curtain plate 31 is erected on the floor surface. After slightly lifting one side plate 5 of the side plates 5, 5 so that the head 64 of the headed engagement tool 6 is positioned in the insertion / removal portions 71, 71 of the engagement fittings 7, 7, the side plate 5 Press down.
Then, when the insertion shaft portions 63 and 63 side of the head portions 64 and 64 move while contacting the inclined guide surface portions 73 and 73, the curtain plate 31 and the side plate 5 of the lower shelf portion 3 are attracted to each other, and the insertion shaft portion 63, 63 are located in the engaging portions 72, 72, and in this state, the heads 64, 64 are formed to have a larger diameter than the engaging portions 72, 72, so that the upper surface of the curtain plate 31 and the upper surface of the side plate 5 Are in a substantially flat state and are firmly connected without separation.
[0016]
Next, the other side plate 5 and the lower shelf 3 are connected in the same manner.
Even if the lower shelf 3 is lifted in a state where the left and right side plates 5, 5 and the lower shelf 3 are connected, the engagement fitting 72 of the side plate 5 is located above the insertion / removal portion 71. Since it is attached in the direction in which it is positioned, the headed engagement tool 6 and the engagement fitting 7 are more engaged, and the left and right side plates 5 and 5 are not accidentally pulled off and are safe.
In order to further strengthen the connection state between the left and right side plates 5, 5 and the lower shelf 3, the lower connection screw holes 34 that coincide with each other when the headed engagement tool 6 and the engagement fitting 7 are engaged are formed. The lower insertion hole 53 is inserted into the connecting screw 50 and the lower shelf 3 and the left and right side plates 5 and 5 are firmly connected.
[0017]
Next, on the left and right side plates 5 and 5 and the lower shelf portion 3 connected as described above, the left and right receiving side plates 22 and 22 of the top plate portion 2 are on the inner surface side of the left and right side plates 5 and 5, and the front end of the top plate 21 is Place it in a position located forward from the completion of assembly. At this time, the upper surfaces of the left and right side plates 5 and 5 support the lower surfaces of the left and right end portions of the top plate 21.
From this state, when the top plate 2 is slid rearward, the locking projections 26 and 26 of the locking brackets 27 and 27 attached to the back surface of the rear end of the top plate 21 are placed on the inner surface of the upper end of the curtain plate 31. The rear end portion of the top plate portion 2 and the lower shelf portion 3 are connected to each other by being fitted into the locking hole 41 of the attached locking bracket 4.
At this time, the upper connecting screw holes 28 and 28 of the left and right receiving plates 22 and 22 of the drawers 25 and 25 are aligned with the upper insertion holes 54 and 54 of the left and right side plates 5 and 5. The part 2 and the left and right side plates 5 and 5 are connected.
[0018]
【The invention's effect】
According to the first aspect of the present invention, the engagement fitting is provided with the inclined guide portion, the insertion / removal portion, and the engagement portion, and the connection between the headed engagement tool and the engagement fitting, that is, between the left and right side plates and the lower shelf portion. The connection can be done easily by one person with simple connection, and the engaging brackets on the left and right side plates are mounted in the direction in which the engaging part is located above the insertion / removal part. The left and right side plates will not come off unexpectedly even if they are removed.
Moreover, since the top plate portion and the lower shelf portion are configured to lock the locking protrusions formed on the top plate portion from the front into the locking holes formed in the lower shelf portion, the lower shelf portion and the left and right side plates Is installed between other items, and the top plate part can be placed on the front from the front, and the top plate part and the lower shelf part can be easily connected by pushing in. In the completed state, it does not take time to install between other articles, and it is not necessary to take an unreasonable posture at the time of connecting work, such as being pulled under the top plate part.
In addition, the top plate and the left and right legs are connected by screws at the upper front end of the side plate, making it easy to work even when the desk is close to the wall and located between other items. It is.
