Abstract

Device for rocking young children with the aid of a vibrating plate driven by an electric motor. The drive means consists of a worm (4) housed in a sheath (5) and driven with a steady linear displacement by the pinion (3) of the reducing gear (2) of a drive motor (9), which causes the vibrating plate (6) mounted on tracks (8) on the device support (1) to move with a back-and-forth rocking motion. Device particularly intended to cause the cot to which it is fitted, and on which the young children are placed, to move with a steady reciprocating motion.

Description

"Device for rocking young children"
French Patent No. 89 06452, to which the present application refers, relates to a device making it possible to rock young children using a vibrating plate set in regular reciprocating motion by an electric motor with using magnets according to this patent, and by a pin according to a first addition.

 The object of the present invention is to propose another means of setting in motion said plate consisting of a flexible worm screw or not associated with the speed reducer with alternating rotation of a drive motor which imparts to it an alternating linear movement. regular.

 This means, in accordance with the present invention, aims to propose a new possibility of producing the device according to the aforementioned patent.

The present invention will now be described in more detail, but without limitation, with reference to the accompanying drawing, in which
Figure 1 is a schematic view, in longitudinal section, of a device.

 Figure 2 is a schematic view, in longitudinal section, of a device whose vibrational plate has been moved by the worm.

 Figure 3 is a perspective view of a device.

 Figures 1 and 2 show the amplitude of the movement of the vibration plate when it is set in motion by the worm.

 In Figure 1 is shown in 1 the support of a device; in 2, a speed reducer with alternating rotation associated with a drive motor not shown; in 3 drive pinion of the worm 4, housed in a sheath 5, imparting a horizontal displacement to the vibrating plate 6; in 7 stud assembling the worm 4 to said plate.

 In FIG. 2 the same elements are shown as in FIG. 1 with a plate 6 which has been moved from its position on the left (see FIG. 1) to a position on the right by the worm 4.

 In Figure 3 there is shown a device whose plate 6 is in a position identical to that of Figure 2 with: in 1 support of a device assembled to a vibrating plate 6 by slides 8; in 9 drive motor and in 2 its speed reducer with alternating rotation associated with a pinion 3 acting on the endless screw 4 housed in a sheath 5 and assembled to the plate 6 by the stud 7.

 The vibrating plate 6 is driven in a regular rocking movement back and forth by the motor 9 using the pinion 3 of its speed reducer 2 acting on the worm 4 which is associated with it by the stud 7.

 Device whose starting and stopping are carried out by an electronic unit with manual, voice and remote controls.

Claims (3)

 an endless screw (4) imparting a regular back and forth movement to the plate (6).  an electrical control box for the device, characterized in that it comprises  an electric drive motor (9)  a vibrating plate (6) generating a rocking movement  1. Device for printing a rocking movement on the various childcare articles on which young children are placed, including  2. Device according to claim 1, characterized in that the speed reducer (2) comprises a pinion (3) allowing said speed reducer to drive the worm (4) in a regular linear reciprocating movement.  3. Device according to claim 1, characterized in that the worm (4) is housed in a sheath (5).
