2. Description of the Related Art Conventionally, a movable wagon desk of this kind has a drawer provided in a main body portion in multiple stages, and is disposed close to one leg plate between both leg plates of a flat desk to provide a desk with sleeves. It can be constructed or installed outside of a leg plate and can be used as a side desk. In a learning desk for school children, this type of separation type is the mainstream in recent years. However, if the height of the top plate of the wagon desk is fixed so that it can be accommodated between the two legs of the flat desk, if it is arranged outside the legs of the flat desk and used as a side desk, The height of the top plate is too low,
It is not easy to use in normal applications, and the top of the wagon desk is mainly used for placing objects such as documents, and the slightly lower height than the desk top is used for mounting OA equipment such as word processors that are more convenient to use. It is used as a mounting table.

[0003] Therefore, the height of the top plate of the wagon desk,
There are two stages: a low state where it can be placed between the two leg boards of the flat desk, and a high state where it is located at the same height as the desk top plate so that it can be used as a side desk by being placed outside the leg plate of the flat desk. In order to enable setting, a structure in which an elevating top plate is connected to a main body via a link type elevating mechanism has been provided.

Next, a structure for releasing the stopper will be described. A long plate-shaped operation lever 31 is provided along the inside of the base 14B of the support member 14, and the operation lever 31 is moved from near the lower surface of the elevating top plate 6 to the gear member 24.
, Which have inclined holes 31A and 31A respectively formed at the lower end and the intermediate part thereof, and which are formed on the inner surface of the corresponding support member 14 by press working so as to protrude.
14D is attached by caulking pins 32, 32 inserted into the inclined holes 31A, 31A. Here, the direction of the inclined hole 31A is such that when the operating lever 31 is lifted and the operating lever 31 is moved upward, the inclined hole 31A is guided by the caulking pin 32 and approaches the gear member 24. When the operation lever 31 is moved in parallel, a pressing piece 31B formed on one side edge of the operation lever 31 presses the protruding piece 27B of the piece 27, and the piece 27 is moved to a leaf spring 26A. The pawl 27A is pulled away from the ratchet 24B by rotating it against the elastic biasing force of the arm.

The main body mechanism section A incorporated in the main body case 29 and the lid body 30 is provided as a pair inside the both side plates 16, 16. The left and right main body mechanisms A, A need to be synchronized.
Therefore, the shaft 25 is connected between the left and right main body mechanisms A, A. One shaft core 2 of the gear member 24
4C penetrates through the lid 30 and is exposed in the drawer housing space in the main body 3, and as shown in FIGS. 10 to 13, a rotary shaft 39 having a square outer shape is provided at the center of the shaft core 24C. It is formed integrally. The rotary shaft 39 forms an engagement groove 40 having a U-shaped cross section with one side parallel to the axial direction being opened, and triangular dowels 41, 41 formed on both sides of the engagement groove 40.
While a square hole 43 formed through the connecting member 42 is slidably engaged with the shaft 25 having a rectangular cross section which can be fitted into the engaging groove 40, and one side portion of the connecting member 42 in the axial direction. The fitting portion 44 formed on the rotary shaft 39 is externally fitted to the rotating shaft 39, and the engaging holes 45, 45 provided in the fitting portion 44 are engaged with the dowels 41, 41 so as to be engaged and connected. . That is, after assembling the main body mechanism portions A, A in the both side plates 16, 16, the connecting members 4 are attached to both side portions of the shaft 25, respectively.
2 and 42 are slid and engaged with the engaging grooves 40 and 40 of the rotating shafts 39 and 39 of each main body mechanism portion A at the same time from the opening direction at both ends of the shaft 25. The shaft 25 can be integrally connected to the rotating shaft 39 for rotation only by fitting the fitting portion 44 of the 42 to the corresponding rotating shaft 39 outside.

Finally, the operation of operating the operation lever 31 to raise and lower the elevating top plate 6 will be briefly described. FIG.
The pawl 27A of the piece 27 is the ratchet 2 of the gear member 24.
4B shows a state in which the gears are engaged with each other. If it is attempted to lower the elevating top plate 6 in this state, a downward force is applied to the support member 14, and a force for rotating the gear member 24 in the counterclockwise direction in the drawing acts via the rack 14C and the pinion 24A. However, the rotation direction is the ratchet 24B and the claw 2
7A meshes strongly, the gear member 24 does not rotate,
Thus, the lowering of the elevating top plate 6 is restricted. On the other hand, the lifting table 6
Is raised, that is, when the support member 14 is moved upward, the gear member 24 rotates clockwise.
A can be performed without rotating the stopper by operating the operation lever 31 while the A rotates while passing over the ratchet 24B.

Next, when the front end of the operation handle 33 located on the lower surface of both sides of the elevating top plate 6 is lifted, the operation levers 31, 31 are moved upward, and the inclined holes 31A, 31A are formed along the caulking pins 32, 32. Is guided, the operating lever 31 moves in parallel to the piece 27 side, and the pressing piece 31
B pushes the protruding piece 27B, the piece 27 rotates against the elastic biasing force of the leaf spring 28, and the pawl 27A
, Whereby the gear member 24 can freely rotate, that is, the stopper is released (see FIG. 11). In this state, the lifting top plate 6 can be lifted and raised. When the desired height is reached, when the finger is released from the operation handle 33, the weight of the operation lever 31 and the elastic biasing force of the leaf spring 28 are applied. And again the nail 27
A is in a state of meshing with the ratchet 24B. here,
The minimum unit in which the height of the elevating table 6 can be adjusted substantially matches the pitch of the teeth of the ratchet 24B, and this pitch is set to 5 mm.
If it is designed to an appropriate degree, the height of the elevating top plate 6 can be adjusted at 5 mm intervals, and it can be used for various height applications.
