The first ends 111a and 112a have quadrilaterals 111a1 and 112a1. An engagement hole 112a2 serving as a through hole is formed in the quadrilateral 112a1. The mesh portion 120a is a metal mesh made of metal such as steel or aluminum provided in the frame 110a. The through hole 121a is formed in the mesh portion 120a. When the inner space of the top plate T is used as a stove space, the through hole 121a is capable of inserting a pawl for supporting a pail or a lantern for hanging a pot or the like on the stove. The girders 130a are angled pipes and are suspended between the stool portions of the frame 110a.

Plates 100b, 100c, and 100d have the same configuration as plate 100a. In FIG. 1A-4, 110a, 110b, 110c is a frame. 111b, 111c, and 111d are the first ends of the frame. 112b, 112c, and 112d are second ends of the frame, 111b1, 111c1, and 111d1 are quadrilaterals of the first end, and 112b1, 112c1, 112d1 are quadrilaterals of the second end. 112b2, 112c2 and 112d2 are engagement holes at the second end. 120b, 120c, and 120d are meshes. 121b, 121c, and 121d are through holes of the mesh portion. 130b, 130c, and 130d are girders.

The hinge 200a allows the plates 100a and 100b to have a substantially L-shaped unfolded state (see FIG. 1C) and a folded state of a substantially I-shape where the plates 100a and 100b overlap each other (see FIG. 3). It is possible to open and close (that is, rotate).

As illustrated in FIG. 1C, the hinge 200b includes the quadrilateral 111c1 of the first end 111c of the plate 100c adjacent to each other and the quadrilateral 111d1 of the first end 111d of the plate 100d. Is connecting. The hinge 200b allows the plates 100c and 100d to have a substantially L-shaped unfolded state (see FIG. 1C) and a folded state having a substantially I shape (see FIG. 3) where the plates 100c and 100d overlap each other. It is possible to open and close (that is, rotate).

As shown to FIG. 1C, the connection part 300a has the substantially U-shaped sheet metal 310a and the pin 320a. Sheet metal 310a has both ends. The distance between the two ends is slightly larger than the sum of the width dimension of the quadrangle 112a1 of the second end 112a of the plate 100a and the width dimension of the quadrangle 112d1 of the second end 112d of the plate 100d. have. For this reason, the quadrilateral 112a1 of the 2nd end part 112a of the plate 100a, and the quadrilateral 112d1 of the 2nd end part 112d of the plate 100d can be fitted between the both ends of the sheet metal 310a. Engaging holes (not shown) are formed at both ends of the sheet metal 310a. The engagement holes of the sheet metal 310a communicate with the engagement holes 112a2 and 112d2 of the sides 112a1 and 112d1 while the sheet metal 310a is fitted to the quadrilaterals 112a1 and 112d1. The pin 320a is inserted into the engagement hole of the sheet metal 310a and the engagement hole 112a2, 112d2 of the quadrilateral 112a1, 112d1, and connects the quadrangle 112a1, 112d1.

As shown to FIG. 1C, the connection part 300b has the substantially U-shaped sheet metal 310b and the pin 320b. Sheet metal 310b has both ends. The distance between the two ends is slightly larger than the sum of the width dimension of the quadrangle 112b1 of the second end 112b of the plate 100b and the width dimension of the quadrangle 112c1 of the second end 112c of the plate 100c. have. For this reason, the quadrilateral 112b1 of the 2nd end part 112b of the plate 100b, and the quadrilateral 112c1 of the 2nd end part 112c of the plate 100c can be fitted between the both ends of the sheet metal 310b. Engaging holes (not shown) are formed at both ends of the sheet metal 310b. In the state where the sheet metal 310b is fitted to the quadrilaterals 112b1 and 112c1, the engagement holes of the sheet metal 310b communicate with the engagement holes 112b2 and 112c2 of the quadrilaterals 112b1 and 112c1. The pin 320b is inserted into the engagement hole of the sheet metal 310b and the engagement hole 112b2 and 112c2 of the quadrilateral 112b1 and 112c1, and connects the quadrangle 112b1 and 112c1.

The leg part L has the rotation leg 410, the reinforcement piece 420, and the reinforcement piece 430, as shown to FIG. 1C and FIG. The rotating leg 410 is a cylindrical pawl, and has one end in the longitudinal direction. One end in the longitudinal direction is axially supported on one of the pair of girders 130a to 130d, respectively. The pivoting legs 410 extend from standing positions (see Fig. 2) along the plates 100a to 100b, respectively, to standing positions (see Figs. 1A and 1D) that are standing approximately perpendicular to the plates 100a to 100b. It is possible to rotate. The convex runner 411 is provided in the rotation leg 410 outside.

The reinforcement piece 420 is a board of long shape. As shown in FIG. 1A and FIG. 1D, the elongate hole 421 extended in the said longitudinal direction is formed in the part of the longitudinal direction side of this reinforcement piece 420. As shown in FIG. The runner 411 of the rotation leg 410 is fitted to the long hole 421 so that a movement is possible. The other end part in the longitudinal direction of the reinforcement piece 420 is axially supported by the outer side part of the frames 110a-110d, respectively. The reinforcement piece 420 is rotatable from the folding position to the suspension position at the other end portion along the rotation of the rotation leg 410. The reinforcing pieces 420 respectively conform to the plates 100a to 100b at the folded positions. The reinforcing piece 420 is suspended between the rotating leg 410 and the feces outside the frames 110a to 110d at the suspension position to support the rotating leg 410.

The reinforcing piece 430 is a plate of long shape. One end part in the longitudinal direction of the reinforcing piece 430 is fixed to the rotation leg 410, respectively. The other end part in the longitudinal direction of the reinforcing piece 430 is axially supported on the inner side of the frames 110a to 110d, respectively. This reinforcement piece 430 is rotatable from the folding position to the suspension position at the other end portion along the rotation of the rotation leg 410. The reinforcing pieces 430 respectively conform to the plates 100a to 100b at the folded positions. The reinforcing piece 430 is suspended between the pivoting leg 410 and the feces inside of the frames 110a to 110d at the suspension position to support the pivoting leg 410.

Hereinafter, the procedure of assembling the folding table of the structure mentioned above is demonstrated in detail. First, the plates 100a and 100b are rotated from the folded state to the unfolded state with the hinge 200a as a point. As a result, the plates 100a and 100b are developed in an approximately L shape. Similarly, the plates 100c and 100d are rotated from the folded state to the unfolded state with the hinge 200b as a point. As a result, the plates 100c and 100d are developed in an approximately L shape.

Thereafter, the quadrilateral 112a1 of the second end 112a of the plate 100a meets the quadrilateral 112d1 of the second end 112d of the plate 100d. Similarly, the quadrilateral 112b1 of the second end 112b of the plate 100b meets the quadrilateral 112c1 of the second end 112c of the plate 100c. In this state, the sides 112a1 and 112d1 are fitted between both ends of the sheet metal 310a, and the sheet metal 310a is attached to the sides 112a1 and 112d1. Similarly, the sheet metal 310b is attached to the quadrilaterals 112b1 and 112c1. Thereafter, the pin 320a is inserted into the engaging holes of the sheet metal 310a and the engaging holes 112a2 and 112d2 of the quadrilaterals 112a1 and 112d1. Accordingly, the quadrilaterals 112a1 and 112d1 are connected. Similarly, the pin 320b is inserted into the engaging holes of the sheet metal 310b and the engaging holes 112b2 and 112c2 of the quadrilaterals 112b1 and 112c1. Accordingly, the quadrilaterals 112b1 and 112c1 are connected.

Then, the rotation leg 410 of the leg part L is rotated from a folded position to a standing position, respectively. Then, the reinforcing pieces 420 and 430 rotate from the folded position to the suspension position. Thereby, the rotation leg 410 stands up at substantially right angle with respect to the plate 100a-100b, respectively. The reinforcing pieces 420 and 430 are suspended between the rotation legs 410 and the frames 110a to 110d.

Hereinafter, the procedure of folding the folding table assembled as mentioned above is demonstrated in detail. First, the rotation leg 410 of the leg part L is rotated from a standing position to a folding position, respectively. Then, the reinforcing pieces 420 and 430 rotate from the suspension position to the folded position. Accordingly, the rotation legs 410 and the reinforcing pieces 420 and 430 respectively follow the plates 100a to 100b.

Thereafter, the pin 320a is pulled out from the engaging holes of the sheet metal 310a and the engaging holes 112a2 and 112d2 of the quadrilaterals 112a1 and 112d1. Thereafter, the sheet metal 310a is separated from the quadrilaterals 112a1 and 112d1. As a result, the connection between the quadrilaterals 112a1 and 112d1 is released. Similarly, the pin 320b is pulled out from the engagement holes of the sheet metal 310b and the engagement holes 112b2 and 112c2 of the quadrilaterals 112b1 and 112c1. Thereafter, the sheet metal 310b is separated from the quadrilaterals 112b1 and 112c1. As a result, the connection between the quadrilaterals 112b1 and 112c1 is released.

Thereafter, the plates 100a and 100b are rotated from the unfolded state to the folded state with the hinge 200a as a point. As a result, the plates 100a and 100b overlap each other and are folded in an approximately I shape. That is, the plates 100a and 100b are folded into the shape of one side of the square ring. Similarly, the plates 100c and 100d are rotated from the unfolded state to the folded state with the hinge 200b as a point. As a result, the plates 100c and 100d overlap each other and are folded in a substantially I-shape. That is, the plates 100c and 100d are folded into the shape of one side of the square ring. Then, as shown in FIG. 4, the folded plates 100a and 100b and the folded plates 100c and 100d are piled up and put in a storage bag, or they are fixed by a band etc. Thereby, the top plate T can be easily carried.

In such a folding table, the quadrilateral 111a1 of the first end 111a of the plate 100a and the quadrilateral 111b1 of the first end 111b of the plate 100b are connected by a hinge 200a. . The quadrangle 111c1 of the first end 111c of the plate 100c and the quadrangle 111d1 of the first end 111d of the plate 100d are connected by a hinge 200b. Therefore, the plate 100a, 100b is folded from the expanded state in a state where the connection between the second end 112a of the plate 100a and the second end 112d of the plate 100d by the connecting portion 300a is released. By rotating over, the plates 100a and 100b can be overlapped and folded in a substantially I-shape. Similarly, the plates 100c and 100d are folded from the unfolded state in a state in which the second end 112b of the plate 100b and the second end 112c of the plate 100c are disconnected by the connecting portion 300b. By rotating over, the plates 100c and 100d can be overlapped and folded in a substantially I-shape. That is, the table is divided into two plates 100a and 100b and plates 100c and 100d, and the plates 100a and 100b are folded to overlap each other, and the plates 100c and 100d are folded to overlap each other. In this manner, the folding table can fold the top plate T compactly, thereby improving portability.

In addition, since the plates 100a, 100b, 100c, and 100d have the same shape, even if the plates 100a, 100b, 100c, and 100d are placed in the storage bag in a stacked state, any one of the plates 100a, 100b, 100c, and 100d may be used. The part does not protrude and come into contact with the user. Also in this respect, portability of the table can be improved.

In addition, the top plate and the folding table mentioned above are not limited to the said Example, It is possible to change a design arbitrarily in the description range of a claim. It will be described in detail below.

In the said Example, it was assumed that the top plate T is a square annular shape. However, the top plate can be arbitrarily changed in design as long as it is an annular or toric of even polygons. That is, the top plate is not limited to the square annular body or the regular hexagonal annular body described later, and the design can be changed into a rectangular annular ring, a hexagonal ring circle, or an octagonal ring circle.

For example, when the top plate is a regular hexagon, as shown in Fig. 5, the six plates 10a to 10f are arranged in an annular polygon of a regular hexagon, which constitutes one side of the regular hexagon and has a right triangle first. It has the end parts 11a-11f and the 2nd end parts 12a-12f of the right triangle on the opposite side to this 1st end parts 11a-11f. The hinge 20a is formed in a substantially V-shaped unfolded state of the quadrilaterals 11a1 and 11b1 of the first ends 11a and 11b of the adjacent plates 10a and 10b, and the plates 10a and 10b overlap each other. It connects so that opening and closing (rotational possibility) is possible between folded states of about I shape. The hinge 20b has a substantially V-shaped open state and the plates 10c and 10d overlapping each other with the quadrilaterals 11c1 and 11d1 of the first ends 11c and 11d of the adjacent plates 10c and 10d. It connects so that opening / closing is possible between the substantially I-shaped folded states. The hinge 20c has a substantially V-shaped open state and the plates 10e and 10f overlapping each other with the quadrilaterals 11e1 and 11f1 of the first ends 11e and 11f of the adjacent plates 10e and 10f. It connects so that opening and closing (rotational possibility) is possible between folded states of about I shape. The connection part 30a detachably connects the quadrilaterals 12a1 and 12f1 of the second ends 12a and 12f of the adjacent plates 10a and 10f to each other. The connecting portion 30b detachably connects the quadrilaterals 12b1 and 12c1 of the second ends 12b and 12c of the plates 10b and 10c adjacent to each other. The connecting portion 30c detachably connects the quadrilaterals 12d1 and 12e1 of the second ends 12d and 12e of the plates 10d and 10e adjacent to each other. The plates 10a to 10f have the same configuration except that the plates 100a differ in length from the plate 100a. Hinge 20a-20c is the same structure as hinge 200a. The connection parts 30a to 30c also have the same configuration as the connection part 300a.

In addition, when a top plate is annular as shown in FIG. 6, several 1/4 circular arc shaped plates 10a'-10d 'are arrange | positioned at the said annular shape, and comprise a part of this annular ring, and are 1st End portions 11a 'to 11d' and second ends 12a 'to 12d' opposite to the first ends 11a 'to 11d' are included. The hinge 20a 'has a half arc-shaped unfolded state and the plates 10a' and 10b 'intersect each other with the first ends 11a' and 11b 'of the adjacent plates 10a' and 10b '. It connects so that opening / closing is possible between the overlapping states of overlapping 1/4 circular arcs. The hinge 20b 'has a half arc-shaped unfolded state and the plates 10c' and 10d 'intersect the first ends 11c' and 11d 'of the adjacent plates 10c' and 10d '. It connects so that opening / closing is possible between the overlapping states of overlapping 1/4 circular arcs. The connecting portion 30a 'detachably connects the second ends 12a', 12d 'of the adjacent plates 10a', 10d 'to each other. The connecting portion 30b 'detachably connects the second ends 12b' and 12c 'of the adjacent plates 10b' and 10c 'to each other. The plates 10a 'to 10d' have the same configuration as the plate 100a except that the shape is a quarter arc. Hinge 20a'-20c 'is the same structure as hinge 200a. The connection parts 30a 'to 30c' also have the same configuration as the connection part 300a. The plates 10a 'to 10d' are not limited to four but can be arbitrarily changed as long as they are an even number of four or more. For example, in the case of six plates, the plate has a 1/6 arc shape and three hinges and connecting portions. In the case of eight plates, the plate has a 1/8 arc shape and four hinges and connecting portions.

The plate mentioned above was set as the structure which has a frame, a net part, and a pair of girders. However, the plates are arranged in an annular shape of an even polygon and constitute one side of the polygon, and also have a first end of a right triangle and a second end opposite to the first end, or are disposed in an annular shape. It is possible to change the design arbitrarily as long as it forms a part of this torus and has a 1st end part and the 2nd end part on the opposite side to this 1st end part. For example, like the top plate T 'shown in FIG. 7, it is possible to make plates 100a', 100b ', 100c', 100d 'into the board of metals, such as wood or aluminum. The configuration other than the top plate is the same as in the above embodiment. Further, even when the top plate is an even polygon or an annular shape other than square, it is possible to configure the plate with the above-described plate.

The second end of the plate is assumed to be a right triangle, but the shape can be arbitrarily changed. For example, as shown in Fig. 8, the second ends 112a '', 112b '', 112c '', 112d '' of the plates 100a '', 100b '', 100c '', and 100d '' are rectangular. It is possible to make a prize. In this case, the connecting portion 300a '' detachably connects the second ends 112a '' and 112d '' of the plates 100a '' and 100d '', and the connecting portion 300b '' is the plate 100b. The first ends 112b " and 112c " of " 100c " are detachably connected. In addition, even when the top plate is an even polygon other than a square, it is possible to change the design of the second end of the plate into a shape other than a right triangle.

In the above embodiment, the plates 100a, 100b, 100c, and 100d have through holes 121a. However, the through hole can be omitted. In addition, the through hole can be formed in at least one of the plates. It is also possible to form through holes in at least one of the plates even when the top plate is an even polygon or an annular shape other than square.

The above-mentioned connection part was supposed to have a sheet metal and a pin. However, it is possible to arbitrarily change the design as long as the connecting portion can detachably connect the second ends of the plates. For example, it is possible to make the connection part into the substantially U-shaped locking piece, and to make the both ends of this locking piece engage with the engagement groove or the engagement hole of the 2nd end of the plate which adjoins each other. Moreover, it is possible to set it as the structure which has the locking piece which can pivot to the 2nd end of one plate among the plates which adjoin each other, and the locking convex part provided in the 2nd end of the other plate. In this case, the second ends of the adjacent plates are detachably connected to each other by turning the locking piece and locking the locking convex portion to the locking recess of the locking piece. In addition, it is not necessary for the whole connection part to be the same structure, and it is possible to set individual connection parts as a different structure.

In the said Example, it was assumed that the table was provided with four leg parts L which have the rotation leg 410 and the reinforcement pieces 420 and 430. As shown in FIG. However, the leg can be arbitrarily changed in design as long as 1) or 2) below. 1) The leg is installed on at least three of the plates of the top plate and is rotatable from a standing position standing up substantially at right angles with respect to the plate to a folding position along the plate. 2) The leg is detachably attached to at least three of the plates of the top plate. As an example of the latter, the leg part can be made into the cylindrical pipe which can be internally fitted or externally fitted to the cylindrical pipe provided in the bottom face of the said plate. In addition, when the leg is fitted inside the pipe of the plate, the leg can be a rod.

In addition, in the said embodiment, the raw material, shape, a dimension, number, arrangement | positioning, etc. which comprise each part of a top plate and a folding table demonstrated the example, It is possible to change a design arbitrarily as long as the same function can be realized. In addition, in the said Example, although the inner space of the top plate T was used as a hearth space, it is not limited to this. That is, the top plate of this invention can be used as a top plate of a normal table.
