Abstract: Mechanical device, electronically actuated and controlled, suitable to support any types of cots for new-born babies, transmitting to said cot a transversal rocking motion, according to a reciprocating translational motion; the legs of the cot are indeed placed on two crossbars, adjustable in length, sliding on two supporting and guiding bases, laying on the ground at the two cot's ends, onto one of which bases the driving unit and the electronic system are installed.

Description: ROCKING DEVICE FOR CRADLES, WITH RECIPROCATING TRANSLATIONAL MOTION, WITH AUTOMATIC STARTING AND STOPPING ON ACOUSTICAL COMMAND The present invention relates to a rocking device for cradles, with reciprocating translational motion, with automatic starting and stopping on acoustical command . In the Italian Patent Application nr. 17 907A/82 it is described a mechanical device suitable to keep lifted from ground any cradle for new-born babies, which remains practically hanging on two support arms situated at the two cot's ends, and rocking around a horizontal longitudinal axis . The action transmitting the rocking motion to the cradle is carried out by a mechanical device comprising a ratio- motor, equipped with worm and worm wheel, onto the shaft of which a crank is applied which, when rotating actuated a lever (or connecting rod) which, through suitable linking and transmission elements, causes the cradle-bearing structure to rock. The start-up of the ratiomotor takes place automatically on command by an electronic system, acoustically actuated by the crying of a new-born baby, which is stected by a ph 0 nic sensor, provided in the said electronic system. It is provided by the invention that, contemporaneously to the rocking action, also a music or anyway a sound transmission is automatically turned on, suitable to facilitate the sleeping of the new-born baby. The object of the present Patent Application, the control electronic system, and the automatic stopping of the ratiomotor in combination with a whatsoever sound transmission remaining the same, is a different preferred embodi- ment of the mechanical structure intended to support the cot, designed, among others, in order to allow a recipro¬ cating ranslati ona I motion of the same, in transversal direction, instead of a rocking motion, as provided by the prior Patent Application N° 17907 A/82. The bearing structure being discussed is character¬ ized by the simpleness and the constructive cheapness, by the practicalness and fastness of installa ion, which does not require the use of any tools, a simple operation of initial location being enough. The invention consists essentially in two individual and link-free bases, each of them being constituted by a "T"-shaped supporting frame, with three lay points at its three ends, on which a horizontal beam, adjustable in length, ending at its ends with two cups or bells, into which two of the four legs of the cradle are to be slid- and supported, is provided. The two frames are positioned transversely at both cot ends, so that the cot may finally carry out transversal trans lati onal motions, driven into reciprocating motion by a crank-and-ti e-rod device, actuated by the usual ratio- motor, installed, together with the box containing the electronic system, on one of the afore said "T"-shaped sug porti ng frames . These latter, compact and light, can be suitably hous ed inside a casing of relalively small size, so that the whole device is suitable to be easily packed and transport¬ ed, without creating any problems as for excessive weight or overall dimensions. For greater explanatory c learness,the disclosure con¬ tinues with reference to the attached drawings, reported to purely illustrative, and surely not limitative purposes, and wherein the preferred embodiment of the present inven¬ tion has been schematically represented. Fig 1 is the side view of one of the two said support ing frames, Fig. 2 is the top view of fig. 2, Fig. 3 is the side view of the other supporting frame, wherein the box containing the ratiomotor and the electron¬ ic system is installed, Fig. 4 is the top iew of fig. 3, Fig. 5 is a side view of a cot mounted on the two said supporting frames. Referring to the said drawings, the structure for sup. porting the cot comprises two supporting bases having a "T"- shaped plan configuration, respectively indicated with the characters (1a) and (1b), each of which is provided, along the vertical flange of the "T", with a pair or rollers (2), spaced apart and idle around a transversal horizontal axis. Each roller (2) is provided with a central race on which a horizontal bar is laying and suitable to slide in a longitudinal direction, such horizontal bar being con¬ stituted by an intermediate tubular element (3a) and (3b), containing two rods axially extractable from opposite sides (4a) and (4b), fastened by wing-head screws (5), and each one ending with a cup or bell (6), suitable to house one of the four feet (P) of the cot (L) (see fig. 5). The tubular rod (3b) of the supporting base (1b) is solid, though a link stud (7), with the foot of a tie- rod (8), the head of which is hinged on to a crank (9), driven to rotate by a ratiomotor, automatically started up and stopped, as already said, by the acoust i ca I ly-command- ed electronic system. In fig. 4 with the number (10) the box has been indi¬ cated, provided on the base (1b), housing the rati oπtotσr,, the crank-tie-rod mechanism and the said electronic s stem. With the number (11) idle rollers have been indicat e d, elastically supported on the base (1a) and (1b), position ¬ ed above and in the middle point of the tubular rods C3a) and (3b), to prevent them to possibly escape out of the respective lay and guide rollers (2). The operating way is as follows: when the new-born baby cries, a sound sensor adjustable in sensibility causa.- the ratiomotor to start up, driving in reciprocating trc-ns- lational motion the tubular rod (3b) and hence the cot "V, whose feet have been placed on and inside the four cups - (6) of the bases (1a) and ' (1b). Contemporaneously with the ratiomotor, a "playback ma¬ chine is started up, it being possible said playback ma¬ chine either to be incorporated inside the box (10), or t be external, provided that it is of the low-voltage type,, as well as a mini radio. transmitter is actuated, it too -. ing either incorporated or external as desired, the sign, of which is detected by a mini-radio receiver, of the po - • able type, so that the concerned people may temporarily leave during the baby's rest, and be anyway istantaneous * ./ warned of his awakening or of his- crying. The electronic system provides of course, after that the rocking time, to be programmed as desired, has elapsed, to automatically switch..off the playback machine and the mini radio transmitter.
