The top plate 100a can be closed to the back side of the top plate 100b by rotating the wing portions 410 and 420 with the bolt of the rotation shaft portion 430 as a fulcrum.

  Hereinafter, a procedure for folding the table having such a configuration will be described. The extension legs 540a and 540b are removed from the rotating legs 510a and 510b. Thereafter, the first and second piece portions 521a and 522a of the suspension member 520a are folded so as to overlap each other. At the same time, the pivot leg 510a and the reinforcing piece 530a are pivoted from the deployed position to the folded position. Thereby, the turning leg 510a, the suspension member 520a, and the reinforcing piece 530a are accommodated in a space partitioned by the U-shaped frame portion 210a and the reinforcing frame 310a. Similarly, the first and second pieces of the suspension member 520b are folded so as to overlap each other. At the same time, the rotating leg 510b and the reinforcing piece 530b are rotated from the deployed position to the folded position. Thereby, the turning leg 510b, the suspension member 520b, and the reinforcing piece 530b are accommodated in a space partitioned by the U-shaped frame portion 210b and the reinforcing frame 310b. The removed extension legs 540a and 540b are locked to the locking portion on the back side of the top plate 100b.

  Thereafter, the top plate 100a is folded to the back side of the top plate 100b. Then, the wing part 420 of the hinge 400 rotates about the rotation shaft part 430, and the lower surface of the plate body 412 inside the wing part 410 and the reinforcing plate 422 of the wing part 420 as shown in FIG. The lower surface of the abuts. At this time, since the end portions 212a1 and 212a2 are located on the inner side of the inner surfaces of the end portions 212b1 and 212b2, the interference between them is avoided. Further, as shown in FIG. 1B, the leg portion 500b and the reinforcing frame 310b are located outside the overlapping region of the top plates 100a and 100b, so that the leg portion 500b and the reinforcing frame 310b interfere with the top plate 100a. Is also avoided. In this state, the male button 230b is fitted to the female button 232a. Thereby, the top plates 100a and 100b are maintained in a closed state.

  In the case of such a table, the U-shaped frame portion 210a and the inner frame portion 220a are attached to the top plate 100a, and the reinforcing frame 310a is suspended between the end portions 212a1, 212a2 of the U-shaped frame portion 210a. 320a is suspended between the intermediate portion 212a3 of the U-shaped frame portion 210a and the frame main body 222a of the inner frame portion 220a so as to be orthogonal to the reinforcing frame 310a. For this reason, the intensity | strength of the top plate 100a can be improved. Further, the U-shaped frame portion 210b and the inner frame portion 220b are attached to the top plate 100b, the reinforcing frames 310b and 330b are suspended between the end portions 212b1 and 212b2 of the U-shaped frame portion 210b, and the reinforcing frame 320b is U-shaped. It is suspended between the intermediate portion 212b3 of the character frame portion 210b and the frame main body 222b of the inner frame portion 220b so as to be orthogonal to the reinforcing frames 310b and 330b. For this reason, the intensity | strength of the top plate 100b can be improved.

  Moreover, the lengthwise ends of the rotating legs 510a and 510b of the legs 500a and 500b are pivotally supported by the intermediate portions 212a3 and 212b3, and the ends of the reinforcing pieces 530a and 530b are fixed to the rotating legs 510a and 510b. The other end is pivotally supported by the reinforcing frames 310a and 310b. That is, since the reinforcement frames 310a and 310b are used as the shaft support portions of the reinforcement pieces 530a and 530b, the number of parts can be reduced as compared with the case where the shaft support portions of the reinforcement pieces 530a and 530b are separately provided. The cost of the table can be reduced.

Further, in a state in which the top plates 100a and 100b are closed, the end portions 212a1 and 212a2 of the U-shaped frame portion 210a are positioned inside the inner surfaces of the end portions 212b1 and 212b2 of the U-shaped frame portion 210b, and the leg portions 500b and the reinforcement The frame 310b is located outside the overlapping region of the top plates 100a and 100b. Therefore, since the U-shaped frame portion 210a is accommodated inside the U-shaped frame portion 210b without interfering with the leg portions 500b and the reinforcing frame 310b, the thickness of the folded main table can be reduced. Further, the pivot leg 510a, the suspension member 520a, the reinforcing piece 530a, and the reinforcing frame 310a of the leg 500a are housed inside the frame main body 212a of the U-shaped frame 210a, and therefore interfere with the U-shaped frame 210b. There is no. Further, the top plates 100a and 100b can be easily locked in a closed state by simply fitting the male button 230b to the female button 232a. The female button 232a is provided on the tongue 231a made of resin with low strength. However, since the thickness of the closed state of the table is small, the top plate 100a, 100b is opened from the closed state. By doing so, the load on the tongue 231a can be reduced.

  Next, a table according to the second embodiment of the present invention will be described with reference to FIGS. The table shown in FIG. 7 includes a pair of top plates 100a '(first top plate), a top plate 100b' (second top plate), a pair of frames 200a ', a frame 200b', and a pair of reinforcing frames 310a ( 1st reinforcement frame), 320a ', reinforcement frames 320b' and 330b ', a pair of hinges 400, and four leg portions 500a (first leg portions).

First, the extension legs 540a and 540e of the legs 500a and 500e are removed as in the first embodiment, the suspension members 520a and 520e are folded, and the rotating legs 510a and 510e and the reinforcing pieces 530a and 530e are moved from the deployed position to the folded position. Rotate. Accordingly, the pivot leg 510a, the suspension member 520a, and the reinforcing piece 530a are accommodated in a space defined by the U-shaped frame portion 210a and the reinforcement frame 310a, and the pivot leg 510e, the suspension member 520e, and the reinforcement piece 530e are U-shaped. It is accommodated in a space defined by the frame part 210e and the reinforcing frame 310e.

  Thereafter, the top plate 100a is closed to the back side of the top plate 100b ", and the top plate 100e is closed to the back side of the top plate 100d. Then, the wing portions 420 of the hinge 400 are rotated about the rotation shaft portion 430, and the lower surface of the plate body 412 inside the wing portion 410 and the lower surface of the reinforcing plate 422 of the wing portion 420 abut each other. At this time, the end portions 212a1 and 212a2 of the U-shaped frame portion 210a are located on the inner side of the inner surface of the frame main body 212b ″ of the X-side frame portion 210b ″, so that interference between the two is avoided. Similarly, the end portions 212e1 and 212e2 of the U-shaped frame portion 210e are located on the inner side of the inner surface of the frame main body 212d of the X-side frame portion 210d, so that interference between them can be avoided. Further, the pivot leg 510a of the leg part 500a, the suspension member 520a, the reinforcing piece 530a, and the reinforcement frame 310a are accommodated inside the U-shaped frame part 210a, so that the pivot leg 510a of the leg part 500a and the suspension member 520a are accommodated. In addition, the reinforcing piece 530a and the reinforcing frame 310a do not interfere with the top plate 100b ″. Similarly, the pivot leg 510e of the leg part 500e, the suspension member 520e, the reinforcing piece 530e, and the reinforcement frame 310e are accommodated inside the U-shaped frame part 210e, so the pivot leg 510e of the leg part 500e, the suspension member 520e, the reinforcing piece 530e, and the reinforcing frame 310e do not interfere with the top plate 100d. Thereafter, the top plates 100b '' and 100d are closed together. Then, the wing 420 'of the hinge 400' rotates about the rotation shaft 430 ', and the surface of the top plate 100a and the surface of the top plate 100e come into contact with each other. Thereafter, the hook 230e is tilted and locked to the pin 230b ''. Thereby, this table is maintained in the folded state.

  In the case of such a table, the U-shaped frame portion 210a and the inner frame portion 220a are attached to the top plate 100a, and the reinforcing frame 310a is suspended between the end portions 212a1, 212a2 of the U-shaped frame portion 210a. 320a is suspended between the intermediate portion 212a3 of the U-shaped frame portion 210a and the frame main body 222a of the inner frame portion 220a so as to be orthogonal to the reinforcing frame 310a. For this reason, the intensity | strength of the top plate 100a can be improved. Similarly, the U-shaped frame portion 210e and the inner frame portion 220e are attached to the top plate 100e, the reinforcing frame 310e is suspended between the end portions 212e1 and 212e2 of the U-shaped frame portion 210e, and the reinforcing frame 320e is U-shaped. The intermediate portion 212e3 of the frame portion 210e and the frame main body 222e of the inner frame portion 220e are suspended so as to be orthogonal to the reinforcing frame 310e. For this reason, the intensity | strength of the top plate 100e can be improved. Further, the X-side frame portion 210d and the Y-side frame portion 220d are attached to the top plate 100d, the reinforcing frame 310d is suspended between the frame main bodies 212d of the X-side frame portion 210d, and the reinforcing frame 320d is attached to the Y-side frame portion. The frame body 220d is suspended so as to be orthogonal to the reinforcing frame 310d. For this reason, the intensity | strength of the top plate 100d can be improved.

  In addition, one end portion of the leg portion 500a in the length direction of the rotating leg 510a is pivotally supported by the intermediate portion 212a3, one end portion of the reinforcing piece 530a is fixed to the rotating leg 510a, and the other end portion is pivoted to the reinforcing frame 310a. It is supported. That is, since the reinforcing frame 310a is used as a shaft support portion of the reinforcing piece 530a, the number of parts can be reduced as compared with a case where a shaft support portion of the reinforcing piece 530a is separately provided. Similarly, since the reinforcement frames 310d and 310e are also used as the shaft support portions of the reinforcement pieces 530d and 530e of the leg portions 500d and 500e, the number of parts is different compared to the case where the support portions of the reinforcement pieces 530d and 530e are separately provided. Can be reduced. Therefore, the cost of this table can be reduced.

  Further, in a state where the top plates 100a and 100b ″ are closed, the end portions 212a1 and 212a2 of the U-shaped frame portion 210a are positioned inside the inner surface of the frame main body 212b ″ of the X-side frame portion 210b ″. It has become. That is, the U-shaped frame portion 210a is accommodated in the frame 200b '' in a state where the top plates 100a and 100b '' are closed. Similarly, in a state where the top plates 100d and 100e are closed, the end portions 212e1 and 212e2 of the U-shaped frame portion 210e are positioned inside the inner surface of the frame main body 212d of the X-side frame portion 210d. That is, the U-shaped frame portion 210e is accommodated in the frame 200d in a state where the top plates 100d and 100e are closed. For this reason, the thickness of the main table in the folded state can be reduced. Further, the main table can be easily locked in a folded state simply by rotating the hook 230e and engaging the pin 230b ''.

  The table described above is not limited to the first to fourth embodiments, and can be arbitrarily changed in design within the scope of the claims.

  In the above embodiment, the table includes a plurality of top plates that can be closed, but it is sufficient that the table includes at least one top plate. Even if there is only one top plate, the first and second frame portions are provided on the side portions of the top plate, and the first reinforcing frame is suspended between the first and second frame portions, whereby the top plate The strength of can be improved. Moreover, in the said Example, although the top plate was taken as the substantially rectangular shape, it can be made into polygonal shape or disk shape (refer FIG. 14). In the latter case, the reinforcing frame 310 (fourth reinforcing frame) may be suspended from the ring-shaped frame portion 200 fixed to the peripheral edge portion of the top plate 100.

  Moreover, although the rotation leg of the leg part mentioned above was provided rotatably in the frame part provided in the side part or peripheral part of the top plate, it is not limited to this. For example, as shown in FIG. 13, a reinforcing frame suspended on X-side frame portions 210f (first and second frame portions) fixed to side portions in the width direction X of the top plate 100f (first top plate). The rotating leg 510f of the leg portion 500f can be pivotally supported by 320f (third reinforcing frame). The leg portion 500f has the same configuration as the leg portion 500a except that the pivot leg 510f is pivotally supported by the reinforcement frame 320. The reinforcing frame 310 has the same configuration as the reinforcing frame 310a. Further, as shown in FIG. 14B, the rotating leg of the leg portion 500 is attached to the reinforcing frame 320 (third reinforcing frame) suspended from the ring-shaped frame portion 200 fixed to the peripheral edge portion of the top plate 100. It is possible to adopt a configuration in which 510 is rotatably supported. The leg portion 500 has the same configuration as the leg portion 500a except that the pivot leg 510 is pivotally supported by the reinforcement frame 320. In addition, although the above-described pivot leg of the leg portion stands up at a substantially right angle with respect to the top plate at the unfolded position, the tilt angle of the pivot leg with respect to the top plate can be arbitrarily set as long as the top plate can be supported. It is. In addition, although the leg part mentioned above was said to be foldable, it should just be able to support a top plate. That is, it need not be foldable.

  Further, the above-described rotating leg of the leg portion can be configured to be pivotally supported by the reinforcing frames 310a, 310b, 310c, 310d, and 310e. In this case, the suspension member is suspended between the rotating leg and the reinforcing frames 310a, 310b, 310c, 310d, and 310e in the deployed position. The suspension member includes the suspension members 520a, 520b, 520c, except that the other end of the first piece in the length direction is pivotally supported by the reinforcement frames 310a, 310b, 310c, 310d, 310e. It can be the same as 520d and 520e. One end of the reinforcing piece is provided on the rotating leg, and the other end is pivotally supported by a frame that faces the reinforcing frames 310a, 310b, 310c, 310d, and 310e.

  Although the above-described leg suspension member has the first and second pieces, the present invention is not limited to this. For example, when the suspension member is a substantially long plate and the base end portion is pivotally supported by the frame portion or the rotation leg, a locking pin is provided on the rotation leg or the frame portion, and the rotation In a state where the leg is in the deployed position, a locking hook provided at the tip of the suspension member is locked to the locking pin so as to be suspended between the rotating leg and the frame portion. It is possible to configure.

  The above-described reinforcing frames 310a, 310b, 310c, and 310e can be arbitrarily changed in design as long as they can be suspended from the frame portion fixed to the side portion of the top plate. Therefore, the reinforcing frame does not need to function as a shaft support portion of the reinforcing piece of the leg portion. Further, the above-described frame portion can be arbitrarily changed in design as long as it is provided on the side portion of the top plate and the reinforcing frame can be suspended.

  Note that the materials, shapes, dimensions, and the like that constitute each part of the table described above are just examples, and the design can be arbitrarily changed as long as a similar function can be realized.
