The base of a locking piece 4 is rotatably attached between the side plates 2, 2 of the frame 1 by means of a support shaft 3, and a claw portion 5 is formed outwardly at the upper end of the locking piece 4. A support piece 7 is cut and raised parallel to the axis of the support shaft 3, and a support piece 7 is erected between both side plates 2, 2, facing the locking piece 4 at a distance, and a part of the support piece 7 is cut and raised inward. The other end of an elastic body such as a spring 9 whose one end is attached to a protrusion 8 formed by cutting and bending is compressed into a recess 10 formed in the inner surface of the upper end of the locking piece 4, and the locking piece 4 is closed. The claw portion 5 of the frame 1 is elastically biased to protrude to the side of the frame 1, and a locking pin 11 is removably screwed and protrudes from the lower surface of the bottom plate 6. The locking pin 11 has a neck portion 12 and a head portion 13 whose diameter is larger than the neck portion 12, and a threaded portion 14 provided at the tip of the neck portion 12 is connected to a screw hole 15 formed in the bottom plate 6 of the frame 1. A predetermined distance is provided between the head 13 and the bottom plate 6. Further, the upper surface of the claw portion 5 is sloped downward to form a sliding surface 16, and the lower surface is sloped outward and has sawtooth-like unevenness to form a non-slip surface 17. Furthermore, the claw portion 5 of the locking piece 4, which is elastically biased laterally by the spring 9, is pushed against the frame 1 more than necessary.
A stopper 18 is provided on the inner surface of the side plate 2 to prevent rotation of the locking piece 4 by cutting and raising a part of the side plate 2 so that the stopper 18 does not protrude from the side plate 2. Furthermore,
The head 13 of the locking pin 11 is shaped so that it can be rotated by connecting a tool such as a screwdriver or spanner.

In this embodiment, the top plate support part B is composed of a sleeve drawer 19 and a leg plate 20, and a top plate 21 is formed at least before and after the upper end of the sleeve drawer 19, and a top plate 21 is also formed at the upper end of the leg plate 20. The upper plate 21 has a pair of locking pins 11 on the front and rear sides of the connector A.
A large number of fastening holes 22, 22 are bored into which the head 13 of the head 13 is fitted and locked. In this embodiment, two pairs of holes are formed on both sides of the sleeve drawer 19, and one pair is formed on the front and rear of the leg plate 20.

They are provided facing oppositely to each other at the front and back.

As shown in FIGS. 1 and 3, the top plate C has a portion of the lower plate 27 cut out corresponding to the stop holes 22, . . . of the front reinforcement 25 and rear reinforcement 26 formed at the front and rear ends of the lower surface, and The accommodating part 28 of the frame 1 is formed by cutting inward and opening downward, and the upper edge of the side wall 29 of the accommodating part 28 is provided with a locking part for locking the claw part 5 of the locking piece 4. A retaining edge 30 is formed. Note that the shape of the storage section 28, that is, the pair of side walls 2
The shape of the frame 1 of the connector A is formed so that the frame 1 of the connector A can be inserted from below without wobbling in accordance with the approximately trapezoidal shape in which the connector 9 is tapered upward.

Therefore, using the connecting tool A, the top plate support part B
When connecting the top plate C to the top plate C, first, as shown in FIG. , by sliding the connector A back and forth,
After being locked to the edge of the stop hole 22, the top plate C is dropped from above as shown in FIG. The frame 1 is inserted, and the claw portion 5 protruding outward from the upper end of the locking piece 4 is locked and connected to the locking edge 30 on the upper edge of the side wall 29 of the housing portion 28. here,
The frame 1 of the connector A is placed in the housing part 28 of the top plate C.
When the claw part 5 is inserted into the frame 1, the sliding surface 16 on the upper surface of the claw part 5 is pushed inward while sliding on the inner surface of the side wall 29 of the housing part 28, and is pushed into the frame 1 against the elastic force of the spring 9. When the frame 1 is completely fitted into the housing part 28, the outer end of the claw part 5 separates from the side wall 29 and projects outward again due to the elastic force of the spring 9. An inclined anti-slip surface 17 locks onto the locking edge 30. In this state, the upper end of the locking piece 4 is always elastically biased outward by the spring 9, and the inclined non-slip surface 1
Since they always make contact at one point 7, they can be reliably locked even if some dimensional error occurs during manufacturing. In addition, when separating the top plate support part B and the top plate C, use a tool inserted from below the upper plate 21 of the top plate support part B to rotate and remove the locking pin 11 of the connector A. As a result, the top plate C is lifted and separated while the frame 1 of the connector A is attached to the top plate C.

[Effect of the invention] According to the device for connecting the top plate and the top plate support portion in the assembled furniture of the present invention, when connecting the top plate and the top plate support portion, the head of the locking pin of the connector is connected to the top plate. It fits and locks into the stop hole formed in the upper plate of the support part, and
Simply drop the top plate from above the top support part and fit the frame of the connector into the accommodation part of the top plate.
The claw portion of the connector is locked to the locking edge by the elastic force of the elastic body, so that the connection can be made very easily and reliably. Also,
When separating, the top plate and the top plate support portion can be separated very easily by rotating and removing the head of the locking pin using a tool inserted from below the upper plate of the top plate support portion. Furthermore, since only the connecting shaft and the locking plate of the connector protrude downward from the upper plate of the top plate support part, when the space below the top plate, that is, the top plate support part is used as a sleeve drawer, The storage space of the topmost drawer can be effectively utilized, and the locking pin can be rotated using a tool inserted into the storage space.
