The support member 5' of the present invention is used to support a foldable mattress support frame, and will be described in further detail with reference to FIGS. 11-18 b:

as shown in fig. 11-11 b, the supporting member 5 ' in the second embodiment is different from the supporting member 5 of the first embodiment in that the lower end 512 ' of the supporting member 51 ' of the supporting member 5 ' in the second embodiment is not directly pivoted to the lower frame 3-4 ', but is pivoted to the lower frame 3-4 ' through a fixing arm 7 ', as follows: the foldable mattress supporting frame comprises an upper frame 1-2 ' and a lower frame 3-4 ' which are both foldable, when the foldable mattress supporting frame is completely unfolded, the upper frame 1-2 ' is parallel to the lower frame 3-4 ', the upper end 511 ' of a supporting body 51 ' of a supporting member 5 ' is pivoted with the upper frame 1-2 ', the lower end 71 ' of a fixing arm 7 ' is fixed on the lower frame 3-4 ', the upper end 72 ' of the fixing arm 7 ' is pivoted with the lower end 512 ' of the supporting body 51 ', therefore, the upper frame 1-2 ' and the lower frame 3-4 ' are connected into a whole by the pivoting of the supporting body 51 ' and the fixing arm 7 ', and the fixing arm 7 ' effectively pivots the lower frame 3-4 ' and the supporting member 5 ' of the invention, so as to realize the function that the upper frame 1-2 ' and the lower frame can rotate with each other, thereby realizing the folding function of the folding mattress support frame.

With continued reference to fig. 11-11 b, more specifically, in order to ensure that the folding mattress support of the present invention does not sway or swing when fully unfolded, the supporting member 5 'in the second embodiment also has a limiting portion 52', the limiting portion 52 'is formed by extending and bending the supporting member 51' towards the end surfaces of the upper frame 1-2 'and the lower frame 3-4', the upper end surface 521 'of the limiting portion 52' is located right below the lower end surface 1-2-1 'of the upper frame 1-2', and the lower end surface 522 'of the limiting portion 52' is located right above the upper end surface 3-4-1 'of the lower frame 3-4'; when the upper frame 1-2 'and the lower frame 3-4' are completely unfolded, the upper end surface 521 'of the position-limiting portion 52' and the lower end surface 1-2-1 'of the upper frame 1-2' are abutted against each other, but the second embodiment is different from the first embodiment in that the lower end surface 522 'of the position-limiting portion 52' is not abutted against the upper end surface 3-4-1 'of the lower frame 3-4'; therefore, in the fully unfolded state, the upper frame 1-2 'is limited to be unfolded continuously by the interference of the limiting part 52' and the lower end surface 1-2-1 'of the upper frame 1-2', and the upper frame 1-2 'and the lower frame 3-4' are connected into a whole through the fixing arm 7 'and the support 5', so that when the upper frame 1-2 'is limited to be unfolded continuously, the lower frame 3-4' is also limited to be unfolded continuously under the action of the fixing arm 7 'and the support 5', and the upper frame 1-2 'and the lower frame 3-4' are unfolded and positioned in a horizontal state, so that a mattress can be horizontally placed on the upper frame, and a powerful guarantee is provided for good rest; meanwhile, in the fully unfolded state, the limiting part 52 ' is abutted against the upper frame 1-2 ', so that the folding mattress support frame does not shake or swing when being fully unfolded, and the supporting part 5 ' of the invention provides stable and reliable support for the upper frame 1-2 ' and the lower frame 3-4 ', further provides stable and reliable support for a laid mattress, and further provides good rest conditions.

Preferably, the fixing arm 7 'is vertically fixed on the lower frame 3-4'; because the fixed arm 7 ' is vertically fixed on the lower frame 3-4 ', when the limiting part 52 ' is abutted against the upper frame 1-2 ', the lower frame 3-4 ' is also in a fully unfolded state and cannot be unfolded continuously, so that the folding mattress support of the invention can not shake or swing when being fully unfolded.

Preferably, the position-limiting portion 52 'and the supporting body 51' are perpendicular to each other,

with continued reference to fig. 11-11 b, in order to improve the folding efficiency and precision of the foldable mattress support frame of the present invention, the upper end 511 'of the support body 51' is bent toward the side surface 1-2-2 'of the upper frame 1-2' and extends to form a first pivot joint 5111 ', and the first pivot joint 5111' is engaged with and pivoted to the side surface 1-2-2 'of the upper frame 1-2'; because the first pivot joint part 5111 'is pivoted by being jointed with the side surface 1-2-2' of the upper frame 1-2 ', the side surface 1-2-2' of the upper frame 1-2 'is in surface-to-surface contact with the first pivot joint part 5111' to rotate when being folded, and because of the joint contact of the first pivot joint part and the first pivot joint part, each connecting rod of the upper frame 1-2 'can only rotate and fold along the surface of the first pivot joint part 5111' when being folded, the folding mattress support frame of the invention is effectively prevented from swinging and deviating when being folded, and the folding efficiency and precision are greatly improved.

As further shown in fig. 11-11 b, in order to further improve the folding efficiency and precision of the foldable mattress support frame of the present invention, preferably, the lower end 512 'of the supporting body 51' extends toward the lateral surface (not shown) of the fixing arm 7 'to form a third pivot-connection portion 5121', and the third pivot-connection portion 5121 'abuts against and is pivotally connected to the lateral surface of the fixing arm 7'; since the third pivot joint 5121 ' is pivoted by being attached to the side of the fixing arm, when folded, the side of the fixing arm 7 ' fixedly connected to the side 3-4-2 ' of the lower frame 3-4 ' is rotated in surface-to-surface contact with the third pivot joint 5121 ', and due to the attachment contact of the third pivot joint 5121 ' and the third pivot joint 5121 ', the connecting rods of the lower frame 3-4 ' can only be rotated and folded along the surface of the third pivot joint 5121 ' in contact with the fixing arm 7 ', thereby effectively avoiding the swinging and deviation of the folding mattress support of the present invention during folding, and further improving the folding efficiency and precision under the action of the first pivot joint 5111 '.
