Each square pipe material is used, and the butt portion is welded. Of course, the upper surfaces of all the frame members 16a to 17c are at the same level and form a continuous flat surface.

  The mesh structure 7 of the load support base 1 includes a large number of longitudinal wires 18 arranged in parallel in the left-right direction at appropriate intervals, and a large number of wires arranged in parallel in the longitudinal direction on the upper side of the longitudinal wires 18. The left and right direction wire rods 19 are configured to be fixed to each other by welding. The mesh structure 7 is placed on the upper surface of the frame structure 6 (the upper surfaces of the frame members 16a to 17c), and the mesh structure 7 The lower front-rear direction wire 18 and the upper surfaces of the frame members 16a to 17c of the frame structure 6 are fixed and integrated with each other by welding. At this time, the front / rear direction wire rods 18a positioned at the left and right ends of the mesh structure 7 are placed near the inner sides of the upper surfaces of the pair of left / right front / rear direction frame members 16a and 16b in the frame structure 6 The wire 19a is configured to protrude slightly outward from the front and rear ends of the pair of left and right front and rear direction frame members 16a and 16b in the frame structure 6. Further, the left and right direction wire rods 19 of the mesh structure 7 are arranged only in a region separated from each of the left and right direction frame members 17a to 17c in the frame structure 6 by an appropriate distance in the front-rear direction. Therefore, only one horizontal wire 19a located at each of the front and rear ends of the mesh structure 7 is disposed outside the left and right frame members 17a and 17b at the front and rear ends of the frame structure 6.

  Like the other panels 2, 3, and 5, the back panel 4 is a mesh in which the vertical wires 20 and the horizontal wires 21 are arranged at appropriate intervals, and the two wires are joined and integrated at the crossing portion by welding. Each of the vertical wires 20 having a required length extending from the lower end of the back panel 4 is bent inward at a right angle to form a front / rear wire portion 20a, on the front end portion of the front / rear wire portion 20a. The bent bottom portion 10 is configured by superimposing the left and right wires 21a and 21b on the intermediate portion and fixing them to each other by welding. The length (width) of the bent bottom portion 10 in the left-right direction is slightly narrower than the length (horizontal width) of the vertical main body portion of the back panel 4 in the left-right direction. When placed at a predetermined position on the rear side portion of the table 1, each of the front and rear direction wire members 20 a is located between two adjacent wires of the front and rear direction wire 18 in the mesh structure 7 of the load support table 1. The left and right direction wire rods 21 a and 21 b are received on the respective front and rear direction wire rods 18 except the front and rear direction wire rods 18 a at both left and right ends of the mesh structure 7. The direction wire 21a is configured to overlap with the rear left and right direction frame member 17b in the frame structure 6 of the load support base 1 in plan view.

  The hinge 11 that connects the bent bottom portion 10 of the back panel 4 having the above-described configuration and the load support base 1 includes three hinge members 22a to 22c. Each hinge member 22a-22c has the same structure, and as shown in FIG. 5C, the belt-like plate is bent into an inverted L shape to form the horizontal mounting plate portion 23 and the vertical mounting plate portion 24, and the horizontal mounting plate. An inverted U-shaped portion 25 that is bent upward from an intermediate position of the portion 23 is formed. As shown in FIG. 4, the hinge members 22a to 22c are arranged at three locations, that is, a substantially central position in the left-right direction of the bent bottom portion 10 of the back panel 4 and two left-right symmetrical positions near both ends. When the inverted U-shaped portion 25 of each hinge member 22a-22c is fitted to the left and right wire 21a at the front end of the bent bottom portion 10 of the back panel 4, the horizontal mounting plate portion 23 is the frame structure of the load support base 1.

  The widths of the hinge members 22a to 22c are such that each of the front and rear direction wire members 20a in the bent bottom portion 10 of the back panel 4 is between two adjacent wire members of the front and rear direction wire 18 in the mesh structure 7 of the load support base 1. In the state located substantially in the center, the distance between the front-rear direction wire part 20a in the bent bottom part 10 of the back panel 4 and the front-rear direction wire 18 in the mesh structure 7 of the load support base 1 adjacent thereto is slightly larger. small. Thus, as shown in FIG. 4, the hinge members 22 a and 22 b at both left and right ends are front and rear direction wire rods at two left and right symmetrical positions near the both ends of the front and rear direction wire rods 18 in the mesh structure 7 of the load support base 1. 18b, 18c and the front-rear direction wire member 20a in the bent bottom side portion 10 of the back panel 4 adjacent to the outside thereof are fixed to the left-right frame member 17b, and the central hinge member 22c is Between the front-rear direction wire 18d at a substantially central position in the front-rear direction wire 18 in the mesh structure 7 of the load support base 1, and the front-rear direction wire 20a in the bent bottom portion 10 of the back panel 4 adjacent to this one side. Is fixed to the left and right frame member 17b.

  Accordingly, the left and right direction wire 21a at the tip of the bent bottom portion 10 in the back panel 4 has the inverted U-shaped portion 25 of each hinge member 22a to 22c and the front and rear direction wire 18 in the mesh structure 7 of the load support base 1 in a side view. The back panel 4 (the bent bottom portion 10) is supported on the right side in the axial direction of the left and right direction wire rod 21a on the left side with respect to the hinge members 22a to 22c. The front and rear direction wire rod portion 20a adjacent to the hinge members 22a and 22c is blocked by contact with the hinge members 22a and 22c. It is blocked by contact with the member 22b. That is, the back panel 4 is attached to the load support base 1 in a state in which the back panel 4 is completely positioned in the left-right direction, and can only move up and down around the left-right direction wire 21a at the tip of the bent bottom 10. Will be.

  As shown in FIG. 4, the coil hinge 9 that connects the side panels 2, 3 and the back panel 4 has vertical wires 20 located on the left and right sides of the back panel 4 and the rear side of the side panels 2, 3. The vertical wire located at is connected. The left and right side panels 2 and 3 are connected between the folding support 15 of the load support base 1 and the front and rear wires 18a at the left and right ends of the mesh structure 7 of the load support base 1. The frame structure 6 is supported by the flat upper surfaces of the left and right front and rear frame members 16a and 16b. In addition, the coil hinge 13 that connects the gate panel 5 and the load support base 1 includes a horizontal wire at the lower end of the gate panel 5 (lower gate panel portion 5a) and a mesh structure of the load support base 1 shown in FIG. 7 is connected to the left and right wire 19a at the front end.

  Each of the frame members 16a to 17c constituting the frame structure 6 of the load support base 1 preferably uses a square pipe material, but a channel material can also be used for a part or all of the frame members. In this case, at least the hinge 11 (hinge members 22a to 22c) is fixed to the left and right direction frame member 17b in a direction in which the lower side is opened. Further, the number of hinge members constituting the hinge 11 is not limited. For example, the central hinge member 22c can be omitted and only two hinge members 22a and 22b can be used. Further, at the place where at least two hinge members 22a and 22b are disposed, the bent bottom portions 10 of the back panel 4 are mutually connected between two adjacent front and rear wires 18 in the mesh structure 7 of the load support base 1. The load supporting base is configured such that two adjacent front and rear direction wire portions 20a are fitted and the hinge members 22a and 22b are fitted between the two adjacent front and rear direction wire portions 20a. Regardless of the mesh structure 7, the back panel 4 can be prevented from moving in the left-right direction by the hinge members 22a and 22b.

  In the above embodiment, the structure of the present invention is adopted in the support portion of the back panel 4 configured in an L shape in a side view, but the gate panel 5 (lower gate panel portion 5a) is in an L shape in a side view. When configured, the left and right direction wire rod at the tip of the bent bottom portion provided in the gate panel 5 (lower gate panel portion 5a) is used as the front left and right frame member 17a in the frame structure 6 of the load support base 1. The structure of this invention is employable as a support part supported on the top.

  FIGS. 6 to 9 show modifications of the hinge 11 that connects the bent bottom 10 of the back panel 4 to the load support 1 so as to be raised and lowered. Each hinge member 26 constituting the hinge 11 is formed by bending a belt-like plate into an inverted U shape and forming a notch recess 28 at the center of the lower side of both vertical plate portions 27a and 27b. Each of the front and rear direction wire rods 18b in the mesh structure 7 of the load support base 1 has a length that can be just fitted between the two front and rear direction wire rod portions 20a in the portion 10. To the left and right direction wire rods 21a at the end of the bent bottom portion 10, the lower sides of the vertical plate portions 27a and 27b are connected to the left and right sides of the frame structure 6 of the load support base 1. It is fixed on the direction frame member 17b by welding.

  According to the structure of the hinge 11 using the hinge member 26, the structure of the hinge member is further simplified as compared with the hinge members 22a to 22c, and the left and right ends of the front end of the bent bottom portion 10 of the back panel 4 are also simplified. Since the hinge member 26 can be fixed to the left and right direction frame member 17b of the frame structure 6 by welding near the portion to be fitted to the directional wire 21a, there is almost no risk of the hinge member 26 being deformed, and the overall strength is increased. Can be planned. Further, a structure in which the two front-and-rear direction wire members 20 a in the bent bottom side portion 10 of the back panel 4 sandwich the hinge member 26 fixed on the left-right direction frame member 17 b on the frame structure 6 side of the load support base 1. Therefore, the position of the back panel 4 in the left and right lateral direction is securely held, and the back panel 4 does not move in the left and right lateral direction.
