AUTOMATIC ROCKING CRADLE

Abstract

 It incorporates a mattress (1) pivoting on the frame by means of projections (2), with limitation of the down or up motion of the longitudinal sides, by means of discs (3) which act as excentrics of a shaft (5) on which is mounted a demultiplication device or a coinoperated direct current motor (6) with simultaneous and synchronous playing of a music or prerecorded sounds, the discs (3) being provided with protuberances (4), having bearings (4') for the alterning resting of the mattress (1), and being situated in a radial position and closer to the extremity, so that the protuberances are on diametrally opposite positions and at different heights with respect to the mattress (1).

Description

OBJECT OF THE INVENTION

[0001] The proposed invention consists in an automatic rocking cradle based on a rigid structure cradle frame and its corresponding mattress which pivots on opposing projections of the mattress located in the center of its respective short sides.

[0002] The mattress has a limited lowering or raising motion of its long sides provided by side disks fitted with mattress supporting projections of different heights which in turn act as diametrically opposite cams in a shaft extending from a direct current motor which is manually activated by a switch, a coin insertion mechanism, a sound detector or some other conventional means, and which also provides the rocking cradle with music or relaxing sounds.

BACKGROUND OF THE INVENTION

[0003] The applicant is not aware of the existence of rigid, fixed cradle frames which possess a means of rocking the mattress, independent from the rest of the cradle, through motor driven means programmed or activated by different methods.

DESCRIPTION OF THE INVENTION

[0004] The invention that is the object of the present specification refers to an automatic rocking cradle based on a rigid structure for the frame, supported by conventional legs and provided with known lateral protectors and possibly anti-tilting means and which incorporates a mattress or equivalent element that pivots on the frame and over opposite lodging extensions of the mattress located in the center of its respective short sides.

[0005] The mattress is provided with a limited lowering or raising motion of its long sides by means lateral disks fitted with mattress supporting projections, so that the mattress leans on one of its long sides, specifically the one in the lower position, over the extension of the corresponding disk projection being applied.

[0006] The disks are identical, their projections being arranged in a radial position closer to the end than to the center, the disks themselves being positioned over the ends of a "U" installed below the mattress and arranged transverse to the mattress, so that the respective projections are positioned diametrically opposite each other and thus at different heights in respect to the mattress.

[0007] The disks in turn act as eccentric diametrically opposite wheels of a shaft extending transversely from a reduction gear or directly from a direct current motor activated either by periodic programming or manually through a switch, or else by means of a coin insertion mechanism, a sound detector or some other conventional means which accompanies the rocking cradle with the playing of music or pre-recorded sounds which have a relaxing effect.

DESCRIPTION OF THE DRAWINGS

[0008] In order to complement the description set forth and provide a better and easier understanding of the characteristics of the invention, a set of drawings is attached to this specification, forming an integral part thereof, wherein the following is represented with an illustrative, non-limiting character:

Figure 1 shows a lower plan view of the rocking cradle frame, the mattress that pivots on the frame, the motor driving means and one of the cradle's conventional driving means.

Figure 2 shows a side elevation section of the invention illustrated in the previous drawing which better illustrates the arrangement of the motor driving means and the mattress activating disks.

PREFERRED EMBODIMENT OF THE INVENTION

[0009] In the light of these figures, the proposed invention shows an automatic rocking cradle fitted with a frame and known fixed side protectors, with or without anti-tilting means, which incorporates a mattress (1) that pivots over the frame by means of projections (2) in the center of its respective short sides, the frame being provided with a limited lowering or raising motion of its long sides by means of side disks (3) positioned over the ends of a "U" placed transverse to the mattress (1), the disks (3) being fitted with projections (4) and extensions at the other end of the disk (3) which receive an alternative support bearing (4') for the mattress and are located in a radial position closer to the end than the center, so that the respective projections are positioned diametrically opposite and at different heights in respect to the mattress (1).

[0010] The disks (3) act as diametrically opposite cams in an extended transverse shaft (5) of a reduction gear or directly from a direct current motor (6) activated either by periodic programming or manually through a switch, or else by means of a coin inserting mechanism (7), a sound detector or some other conventional means which synchronously accompanies the rocking cradle with the playing of music or pre-recorded sounds.

[0011] This description is not made more extensive in the understanding that an expert on the subject will have sufficient information to perceive the scope of the invention and the advantages deriving therefrom, and also to reproduce said invention.

[0012] It should be understood that, provided the essence of the invention is not altered, the materials, shape, size and arrangement of the elements are liable to variation.

[0013] The terms used in this description, and their meaning, must always be taken in a non-limiting sense.

Claims

1. Automatic rocking cradle of the type fitted with a frame and known fixed side protectors, with or without anti-tilting means, essentially characterized in that it incorporates a mattress (1) that pivots over the frame by means of projections (2) in the center of its respective short sides, the frame being provided with a limited lowering or raising motion of its long sides by means of side disks (3) positioned over the ends of a "U" placed transverse to the mattress (1), the disks (3) being fitted with projections (4) with alternative supporting bearings (4') for the mattress (1) located in a radial position closer to the end than the center, so that the respective projections are positioned diametrically opposite and at different heights in respect to the mattress (1).

2. Automatic rocking cradle according to the preceding claim, characterized in that the disks (3) act as diametrically opposite cams fitted onto the extended transverse shaft (5) of a reduction gear or directly on the shaft of a direct current motor (6).

3. Automatic rocking cradle according to the preceding claims, characterized in that the motor (6) is programmed for periodic activation, or else is manually activated by a switch, by a coin inserting mechanism (7), a sound detector or some other conventional means.

4. Automatic rocking cradle according to the preceding claims, characterized in that its motion is accompanied by the simultaneous and synchronous playing of music or pre-recorded sounds.
