A cradle includes first and second frames in the form of an inverted “U”, the legs thereof crisscrossing and being connected to one another by sliding clamps in the crisscrossing point. Above the crisscrossing points, the structure has a third frame supporting a basket. The third frame is hinged to opposite points of the legs of the second frame and linked to the first frame so that altogether there are at least three connecting points between the first, second and third frames. An element adjustably joining both parts of the first and second frames is provided beneath the crisscrossing points, the element fixing the degree of opening between the frames thereby regulating the height of the basket.

Cradle according to claim 6, wherein between said small sliding block and said ball the cords pass through a central hole of the other ball which acts as safety stop for the small sliding block and between both balls there is a knot of the cords which acts as limit of the ball run and in that the ball comprises a plane facing said knot and two slots parallel on said plane on both sides of its central hole, said ball, with the whole of the cradle in folded disposition, passes between the two cords, at a length higher than them, retaining them in said slots and trapping the opposite element securing the folded disposition.8. Cradle according to claim 5, wherein said sliding joining clamps are constituted by a cord describing a curved path and that within it loosely encompasses the leg of a corresponding first or second frame, the ends of said cord being fastened on respective holes of the other corresponding first, second or third frame.9. Cradle according to claim 8, further comprising a pair of plugs slidingly linked to the legs of the first or second frame by a piece of rope, said plugs have at least a portion having a shape and size suitable for the sizes of the cross section of said legs of the first or second frame and to the length of said cord forming clamps in order to temporarily and substantially lock the relative motion between frames by stretching clamps produced by the insertion of said portion of said plugs at the crossing areas either between the legs of first and second frames or between said first or second frame and the ropes forming clamps.10. Cradle, according to claim 1, wherein said cot is formed by said third frame which is in a form of a higher ring, a lower ring supported on said higher ring, a side and a bottom of the cot.11. Cradle according to claim 10, wherein said side and bottom are made of a flexible textile material and the side and the bottom are joined to each other, the side includes on an internal face and close to the bottom, a perimetric flange projecting inwardly from the cot by an elastic cord or ribbon associated with it, trapping the lower ring of the cot in an easily releasable way and a second perimetric elastic ribbon associated to the side at a given height of said flange tends to close the side of the textile material forming a gullet above a mattress trapping it slightly in an easily releasable way.12. Cradle according to claim 11, wherein said side comprises a series of equidistant lower curls, formed upwardly overhanging by large bands or ribbons sewed on its external face and a series of equidistant higher curls downwardly directed, formed by other large bands or ribbons which start from the higher edge of the side of the textile material folding on the higher ring, said higher curls remain in intercalated positions with said lower curls and a smooth rope with its yarns fastened in a loop is passing consecutively and alternately through all its curls linking the textile side together with the bottom to the higher ring.13. Cradle according to claim 10, further comprising a supporting surface joined to said lower ring of the cot covering the internal area thereof, forming as a whole a bed base for a mattress, the material of said supporting surface is selected from a continuous laminar material; an openworked or perforate laminar material; and a laminar material obtained by braiding, interlocking or interweaving half rigid artificial or natural fibres including osier basketwork or meshing of cane strand.14. Cradle according to claim 1, wherein each of the first and second frames comprises between its legs at least a respective joining crossmember tightly fixed by its ends, by an element to the section of said legs.15. Cradle according to claim 14, wherein said crossmembers are straight or arcuate or elbowed with their top part concave and close to each crossmember, a reinforcing crossmember is provided arcuate or elbowed at its convex top part.16. Cradle according to claim 14, wherein said element for fastening the degree of opening between the legs of the first and the second frames is constituted by an oblong ring hinged to said crossmember which is joining the legs of the second frame and provided with a series of appendages which protrude from an opposite end, which is geared or coupled on said other crossmember which joins the legs of the first frame, an elastic element being arranged associated to said ring actively assisting to the opening and closure of the set, constituted by at least a flexible cord joined by one of its ends to the end which has said appendages of the ring said flexible cord extending under said crossmember of the first frame and is joined by the other end to said frame or attached reinforcement of the second frame or to the end distal to the ring.17. Cradle according to claim 16, wherein the inside of said ring-shaped fastening element is occupied by a grating acting as a rack.18. Cradle according to claim 17, wherein the fastening of ropes to cored or uncored tubular elements of frames or crossmember comprises an end sector of rope, with its strands heat fused, introduced in a hole for respective tubular elements and at least one fastening element for fastening rope in position within said hole.19. Cradle according to claim 18, wherein said fastening element comprises at least one pin introduced from outside an uncored or cored tubular element crossing rope within the hole.20. Cradle according to claim 19, wherein said hole is blind and a metallic sleeve is arranged around rope within the hole and with a flanged end at the mouth, said metallic sleeve being also crossed by said pin which is at least one.21. Cradle according to claim 19, wherein said hole is a through hole and a metallic sleeve is arranged around rope within the hole and with both ends flanged at the mouths, said metallic sleeve being also crossed by said pin, which is at least one and with a finishing tack stuck in the fused end of the rope.22. Cradle according to claim 18, wherein said tubular element is a cored metallic tube and said hole is a blind hole, said fastening element comprising an anchoring part of a plastic material, which has its end heat fused together with a final end of said rope passed through a central hole of toothed walls of said anchoring part, which externally shows at its external end a stop the rib and under it a wedge-shaped protruding configuration which allows to introduce under pressure the anchoring part together with the rope in the hole until stopping against the rib and preventing the withdrawal thereof when edges of the hole are trapped between the rib and protruding configuration.23. Cradle according to claim 16, wherein said hinged junctions of the ring to the crossmember and the third frame to the frame comprise small lengths of flexible cord and with possibility of twisting, with its ends fixed on respective ring and crossmember or second and third frame.24. Cradle according to claim 14, wherein said element for fixing the degree of opening between the legs of the first and second frames is constituted by an oblong ring provided with two distal ends protruding overhanging above said crossmembers, at the ends of which are arranged a series of appendages which may be respectively geared or coupled on said crossmembers, remaining fastened to them by an elastic element which starts from one of the parties of said distal ends of the ring and extending under said two crossmembers.25.
