  • The legs in each row are of two types: one is the first leg 10, which is a two-section retractable one that comprises the first external tube 11 and the first internal tube 12 sliding-connected in the external tube 11. The first lower pivot receptacle is provided at the bottom end of the first external tube 11, the first intermediate pivot receptacle at the top end of the first external tube 11 and the first upper pivot receptacle at the top end of the first internal tube 12; the other is the second tube 20, which is a three-section retractable one that comprises the second external tube 21, the intermediate tube 22 sliding-connected in the second external tube 21 and the second internal tube 23 sliding-connected in the intermediate tube 22. The second lower pivot receptacle is provided at the bottom end of the second external tube 21, the second intermediate pivot receptacle at the top end of the intermediate tube 22 and the second upper pivot receptacle at the top end of the second internal tube 23.
  • Each row of legs includes three first legs 10 and two second legs 20 and the said three first legs 10 and two second legs 20 are arranged alternatively. Each pair of the adjacent front-back first leg 10 and the second leg 20 in each row are connected with a "cross" folding frame 30, whose two lower ends are connected respectively with the first lower pivot receptacle at the bottom end of the first external tube 11 and the second lower pivot receptacle at the bottom end of the second external tube 21, whose upper ends are connected respectively with the first upper pivot receptacle at the top end of the first internal tube 12 and the second middle pivot receptacle at the top end of the intermediate tube 22.
  • According to the need, the left-right corresponding legs of the two rows of legs are connected with a "cross" folding frame between them, and a horizontal beam 14 is fixed between the first middle pivot receptacles at the top end of the first external tubes 11 of the two first legs 10 and another horizontal beam 24 is fixed between the second upper pivot receptacles at the top end of the second internal tubes 23 of the two second legs 20.
  • The general plane frame includes four sub-plane frames 40 comprising two longitudinal beams 41 and at least one horizontal beam 42 fixed between the two horizontal beams 41.
  • If necessary, short reinforcing members can be fixed between two horizontal beams 42. The both ends of the longitudinal beams 41 are pivot-connected correspondingly to the first middle pivot receptacle at the top end of the first external tube 11 of the first leg 10 and the second upper pivot receptacle at the top end of the second internal tube 23of the second leg 20. The tandem pivot-connection of the first and the second upper pivot receptacles enables the four sub-plane frames 40 to form an organ-type folding.
    • No.2 Embodiment Example
  • Please see Figs 4, 5 and 6. The folding bedstead comprises two left-right paralleled rows of legs and the general plane frame.
  • The legs in each row are of two types: one is the first leg 10, which is un-retractable and is provided with the first lower pivot receptacle at the bottom end and the first upper pivot receptacle at the top end; the other is the second leg 20, which is a three-section retractable one that comprises the second external tube 21, the intermediate tube 22 sliding-connected in the second external tube 21 and the second internal tube 23 sliding-connected in the intermediate tube 22. The second lower pivot receptacle is provided at the bottom end of the second external tube 21, and the second upper pivot receptacle at the top end of the second internal tube 23.
  • Each row of legs includes three first legs 10 and two second legs 20 and the said three first legs 10 and two second legs 20 are arranged alternatively.
  • According to the need, the left-right corresponding legs of the two rows of legs are connected with a "cross" folding frame between them, and a horizontal beam 14 is fixed between the first upper pivot receptacles at the top end of the two first legs 10 and another horizontal beam 24 is fixed between the second upper pivot receptacles at the top end of the second internal tubes 23of the two second legs 20.
  • The general plane frame includes four sub-plane frames 40 comprising two longitudinal beams 41 and at least one horizontal beam 42 fixed between the two longitudinal beams 41.
  • If necessary, short reinforcing members can be fixed between two horizontal beams 42.
  • The both ends of the longitudinal beams 41 are pivot-connected correspondingly to the first upper pivot receptacle at the top end of the first leg 10 and the second upper pivot receptacle at the top end of the second internal tube 23 of the second leg 20. The tandem pivot-connection of the first and the second upper pivot receptacles enables the four sub-plane frames 40 to form an organ-type folding.
    • No.3 Illustrative Example
  • Please see Fig. 7. This example is a kind of air bed comprising an air mattress 50 and a folding bedstead. The air mattress 50 comprises a mantle and an inflation internal core.
  • The mantle is provided with a closable opening, enabling the client to either put the inflation core in the mantle or to take it outside the mantle according to the need. The folding bedstead is as described in No. I Embodiment Example. The said mantle is connected on the first and second pivot receptacle of the bedstead.
