Claims

[Scope of utility model registration request]

(1) The central base is pivotally supported on the base so as to be able to move up and down, and can be rotated between a horizontal unfolded position where they are adjacent to each other on the same plane, and a folded position where they are folded in the middle and are in an upright position. a pair of top plate support frames, a top plate stretched on each of the frames, and collapsible/deployable pedestals whose upper ends are pivoted to each of the frames at separated positions sandwiching the base. and a stay that spans between the pedestal and the base and is pivotally supported by the pedestal so as to be tilted gradually downward toward the pedestal side when the top support frame is expanded. In a folding structure, the pedestal and top support frame. A center-fold type % type % characterized in that a spring for applying a tensile force to the pedestal is stretched between the frame and the stay at a position separated above the stay when the frame is expanded.

(2) The center-folding structure according to claim 1, wherein the spring has a tension adjusting means.

(3) Each top plate has a hole chamber whose lower surface side is open at a position corresponding to a pivot point of the top plate support frame relative to the base, and the pivot point is housed in the hole chamber. A center-folding type folding structure according to claim 1 of the utility model registration claim.

(4) The base has a frame structure and integrally has an upwardly facing bracket on the upper end side, and an upwardly facing gusset plate integrally formed with the top plate support frame is pivotally supported by the bracket in the hole chamber. A center-folding structure according to claim 1 or 3, characterized in that:

(5) On the mutually opposing surfaces of the top plates that will be joined when unfolded.
2. The center-folding structure according to claim 1, wherein tapered surfaces are provided between the tapered surfaces to form a gap that gradually becomes wider on the lower side.
