As shown in FIG. 3, the foldable table 200 includes a top plate 210 indicated by a broken line having a shape in which a side on the seating side of a quadrilateral plate material is cut off in an arc shape. A pair of rectangular leg support plates 220 are erected on the top plate 210 along the longitudinal direction of the top plate 210 on both the left and right sides of the lower surface of the top plate 210. The leg support plate 220 has an inclination that spreads outward as it goes downward (see FIG. 4). A rectangular reinforcing plate 230 having the same height as the leg support plates 220 is connected to the leg support plates 220 and fixed to the front lower surface of the top plate 210 in the vertical direction. Two recesses are formed in the bottom surface of the leg support plate 220, and one fixing plate of the hinge 240 is fixed to each of the recesses so that the rotation axis thereof is along the lower corner on the outer side of the leg support plate 220. . The other fixing plate of the hinge 240 is fixed to the inner surface on the upper end side of the pair of left and right leg portions 250, and the leg portion 250 is attached to the top plate 210 via the leg support plate 220 around the rotation axis of the hinge 240. It is attached so that it can tumble.
[0029]
The leg portion 250 is a trapezoidal ring-shaped plate as shown by a broken line in FIG. 2, and the end edge 251 on the rear end side is substantially the same as the rear end of the seat portion 350 of the drawer-type chair, or from the seat portion 350. Also protrudes to the rear end side. As shown in FIGS. 2 and 3, the front end edge 252 of the leg portion 250 is substantially flush with the front end edge 211 of the top plate 210. A non-slip thermoplastic elastomer (not shown) is attached to the bottom surface of the leg portion 250. In addition, a die-shaped stopper 260 made of an elastic material such as rubber or thermoplastic elastomer is fixed to the center of the lower surface of the reinforcing plate 230.
[0030]
As shown in FIGS. 1B and 2, the leg portion 250 having a ring shape has an upper plate 253, a bottom plate 254, and an oblique plate 255 connecting them, and the upper plate 253 includes As shown in FIG. 4, a hole penetrating in a substantially vertical direction is formed along the center of the thickness of the upper plate 253, and a fixing pin 270 is slidably mounted in this hole. The head portion 271 of the fixing pin 270 has a round and protruding shape, and protrudes from the lower surface of the upper plate 253 of the leg portion 250. The fixing pin 270 is urged by an urging means (not shown) so that the tip end 272 always protrudes from the upper end of the leg 250. The tip 272 of the fixing pin 270 is the upper end of the upper plate 253 of the leg 250. The head 271 of the fixing pin 270 is gripped and pulled to be buried in the upper plate 253. Further, the distal end portion 272 of the fixing pin 270 is buried in the upper plate 253 by being pressed. As described above, the distal end portion 272 of the fixing pin 270 can freely protrude from the upper end of the leg portion 250. On the other hand, as shown in FIG. 4, the top plate 210 has a distal end of the fixing pin 270 at a position where the distal end portion 272 of the fixing pin 270 contacts the lower surface of the top plate 210 when the leg portion 250 is raised. An insertion hole 212 into which the portion 272 is inserted is provided.
[0031]
When the leg portion 250 is raised most about the rotation axis of the hinge 240, as shown in FIG. At the same inclination as the support plate 220, the leg portions 250 are in an upright state in which the legs 250 are opened outward. In the standing state, the upper end of the leg portion 250 is slightly separated from the lower surface of the top plate 210. When the leg portion 250 is in the most closed state with the rotation axis of the hinge 240 as the center, as shown by a broken line in FIG. The folded state is separated by the width and substantially parallel to the top plate 210. In this folded state, as shown in FIGS. 1B and 4, the bottom surfaces of both leg portions 250 are pressed against the stopper 260, and the stopper 260 is deformed to deform the stopper 260 to the lower end edge of the leg portion 250. The leg portion 250 is maintained in a folded state. Since a non-slip thermoplastic elastomer (not shown) is attached to the bottom surface of the leg portion 250, the frictional resistance against the stopper 260 is large, and the leg portion 250 is stably held by the stopper 260.
[0032]
As shown in FIG. 2, a plate spring member 280 as an urging means is attached to a portion of the inner surface of the leg portion 250 above the rotation axis of the hinge 240. When the leg portion 250 is in an upright state, the leaf spring member 280 presses the leg-shaped plate spring 281 against the leg support plate 220 and biases the upper inner surface of the leg portion 250 outward from the leg support plate 220. It is supposed to be. Accordingly, the leaf spring member 280 biases the leg portion 250 to the folded state when the leg portion 250 is in the standing state.
[0033]
As the leg portion 250 is raised from the folded state to the standing state, the distal end portion 272 of the fixing pin 270 comes into contact with the lower surface of the top plate 210 and then is pressed to reduce the protruding amount, but the leg portion 250 is raised. When the state is reached, it enters the insertion hole 212 with a biasing force of a biasing means (not shown). Thereby, since the front-end | tip part 272 of the pin 270 for fixation is fixed by the insertion hole 212, and the rotation position of the leg part 250 is fixed, the leg part 250 can be maintained in an upright state.
[0034]
When the leg portion 250 is in the standing state, when the head portion 271 of the fixing pin 270 is lifted and the distal end portion 272 of the fixing pin 270 is removed from the insertion hole 212, the leg portion 250 is very small by the urging force of the leaf spring member 280. It is possible to automatically prevent the distal end portion 272 of the fixing pin 270 from coming out of the insertion hole 212 and the distal end portion 272 of the fixing pin 270 from entering the insertion hole 212 again by rotating slightly to the folded state side. .
[0035]
This foldable table 200 is fixed by a stopper 260 when both legs 250 are folded, and the folded state is maintained. Further, since the front end edge 211 of the top plate 210 and the front end edge 252 of the leg portion 250 are separated and are substantially on the same plane, the folded table 200 is placed with the front end side down as shown in FIG. You can stand on the floor. Therefore, the foldable table 200 of the present invention can be stored in an upright state, and the area required for storage can be reduced, and thus the storage capacity is excellent.
[0036]
The drawer-type chair 300 of the present invention is not limited to the foldable table 200 of the present invention, and can be attached to a general table. However, in the following description, the foldable table 200 is used as a table to be attached. I will explain.

The second rotating roller 378 is housed so as to be rotatable about a shaft rod 377 in a direction orthogonal to the central axis direction of the cylindrical portion 371. The upper end of the second rotating roller 378 protrudes above the upper end edge of the opening of the roller storage chamber 372.
[0044]
When the distal end portion of the linear arm portion 331 is inserted into the cylindrical portion 371 of the retaining member 370, the fixing button 333 of the linear arm portion 331 is pushed by the inner surface of the cylindrical portion 371 and the outer surface of the linear arm portion 331. When the straight arm portion 331 continues to be inserted, the distal end of the fixing button 333 engages with the fixing hole 373 and the distal end of the fixing button 333 enters the fixing hole 373. The fixing button 333 and the fixing hole 373 engage with each other by the urging force. As a result, the retaining member 370 is fixed to the distal end portion of the linear arm portion 331. Therefore, the retaining member 370 can be detachably attached to the U-shaped arm member 330 by the engagement between the fixing button 333 and the fixing hole 373.
[0045]
When the retaining member 370 is fixed to the distal end portion of the linear arm portion 331, when the linear arm portion 331 is moved back and forth using the guide portion 312 as a guide, the second rotating roller 378 is moved to the lower surface of the table top plate 310. Has a function of smoothing the forward and backward movement of the linear arm portion 331.
[0046]
When the chair-equipped table 10 is assembled and used, as shown in FIG. 1 (a), when both legs 250 are opened, the leaf spring member 280 is placed immediately before the legs 250 are in an upright state. The urging force becomes resistance to the opening of the leg portion 250. Further, the distal end portion 272 of the fixing pin 270 is also pressed against the lower surface of the top plate 210, so that a weak resistance is generated. When the leg portion 250 is further opened against these resistances, the distal end portion 272 of the fixing pin 270 automatically enters the insertion hole 212 by the action of a biasing means (not shown). The legs are stopped, and the legs 250 are fixed in a state where the legs 250 are in contact with the leg support plate 220. Therefore, this table 10 with a chair can maintain the standing state of the leg part 250 only by opening the leg part 250.
[0047]
In a state in which both legs 250 are opened, the bottom surface of the leg 250 is positioned in the vicinity of the left and right side edges of the top plate 210, and the rear end edge 251 of the leg 250 has the seat portion 350 and the table top plate 210. It extends to a position close to the rear edge of the seat portion 350 in the state of being pulled to the side. On the other hand, the front end edge 252 of the leg portion 250 is located on the same plane as the front end edge of the top plate 210. Therefore, even if an infant sits on the seat part 350 of this table 10 with a chair, stability is very high.
[0048]
Since the linear arm portion 331 can slide the guide member 310 in the front-rear direction, the seat portion 350 can be moved in a pull-out manner. When the position of the seat portion is changed, the linear arm portion 331 is supported by the first rotating roller 316 of the guide member 310, and the second rotating roller 378 at the distal end portion of the linear arm portion 331 covers the lower surface of the top plate 210. Since it rolls, the force for changing the position of the seat portion 350 is small, and the position can be changed smoothly.
[0049]
When the infant is seated on the seat portion 350, the seat portion 350 is pulled out to the rear side so that the distance between the top plate 210 and the seat portion 350 is increased to make it easier to sit, and after the infant is seated on the seat portion 350, the seat The infant 350 can eat and play on the top board 210 by pushing the part 350 toward the top board 210 side.
[0050]
Since the hard plate 351 is incorporated in the seat plate 352 of the seat portion 360, the seat portion 350 is in a state of floating in a hollow state, but has a good sitting comfort.
[0051]
When the infant is taken out from the seat portion 350, the seat portion 350 is pulled out to the rear side to increase the distance between the top board 210 and the seat portion 350, and the infant can be taken out after making it easier to hold the infant.
[0052]
When the table with chair 10 is stored, if the head portions 271 of the fixing pins 270 of both the leg portions 350 are pulled out and the distal end portion 272 of the fixing pin 270 is extracted from the insertion hole 212, the urging force of the leaf spring member 280 The leg 250 is forcibly separated from the leg support plate 220 by a very small amount. As a result, the distal end 272 of the fixing pin 270 comes out of the insertion hole 212 and presses the lower surface of the top plate 210, and the fixing pin 270 does not enter the insertion hole 212 again. As shown by the broken line in FIG. 4, when the leg portion 250 is closed until it is substantially parallel to the top plate 210 in this state, the leg portion 250 is separated by the width of the top plate 210 and the leg support plate 220 and folded by the stopper 260. State is maintained. Therefore, the operation of folding the leg portion 250 may be performed simply by pulling out the head portion 271 of the fixing pin 270, folding the leg portion 250, and pressing the leg portion 250 on the stopper 260. And since the front end edge 252 of the leg part 250 and the front end edge 211 of the top plate 210 exist on the substantially same surface, as shown in FIG.1 (b), the front end edge 252 of the leg part 250 is turned down and it is a floor surface. When placed in the table, the table with chair 10 is self-supporting. Therefore, it is excellent in storage property.

When the seat portion 350 is dirty and needs to be washed, the fixing button 333 is pushed down from the attaching / detaching hole 374 with a screwdriver or the like, and the locking between the fixing button 333 and the fixing hole 373 is released and the retaining button 333 is retained. Both members 370 are extracted from the U-shaped arm member 330. Thereafter, the U-shaped arm member 330 can be extracted from the guide member 310, and the pipe passage 353 of the seat portion 350 can be extracted from the U-shaped arm member 330 by sliding the U-shaped arm member 330. When the U-shaped arm member 330 is removed and only the folding table 200 is used, the U-shaped arm member 330 is extracted from the guide member 330 by the same operation. In this case, since the fixing button 333 protrudes from the outer surface of the linear arm portion 331, the guide member 310 must be depressed from the outer surface of the linear arm portion 331 by pressing down the fixing button 333 when being extracted from the guide member 310. I can't pull it out. For this reason, even if the retaining member 370 is not mistakenly attached, the U-shaped arm member 330 does not come off from the guide member 310 due to the protrusion of the fixing button 333, so that the safety is excellent.
[0054]
When only the foldable table 200 is used, the opening on the rear end side of the guide member 310 can be covered with the shutter 320. Therefore, it is possible to prevent an infant or the like from inadvertently putting a finger or the like, and the safety is excellent.
