DESCRIPTION

Rocking device for baby carriages.

Technical sector

The sector of the technique of the present invention is the manufacture of accessories for baby carriages and, as its own title indicates, the object thereof is a device adaptable to any car or baby chair, which it generates from the corresponding electromechanical device a movement of the cart that is compatible with the sleep cycle of a baby.

This device performs a cyclic, slow and short distance movement (0.5-1.5 meters), which helps the baby to sleep due to the cyclic rocker movement, freeing his parents or caregivers from doing it manually. This device is independent of the cart itself and adaptable to any model and type of baby carriage, so that its acquisition can be made even without knowing the model of the same to which it is intended, while it can be placed or uninstalled from the carriage Quick and easy way.

State of the art

There are multiple references in the state of the art to rocking devices for cribs and baby carriages, since it is proven that children tend to fall asleep inside the car, particularly when it is in motion, and preferably when it has a certain rocking motion. Some of these devices are gadgets that are deposited on the floor, which through a connecting rod or a similar simple mechanism transmit a reciprocating motion to the baby's stroller or cradle.

Another more advanced solution is represented by a series of mechanisms formed by a set that engages and disengages with respect to the frame of the baby carriage, which includes a two-way rotation mechanism, driven through a transmission by means of a motor whose Turning movements in both directions are commanded by a controller associated with an electric battery powered by the motor itself, whose movement results in a displacement of one of the wheels of the cart. Among other documents of this nature, the following are noteworthy: ES2017287, ES1102081, WO2014070008, US9027689, US20150197271 or US20160107670.

However, all the mechanisms mentioned in the previous point actuate only one of the wheels of the cart, so that the movement of this as a whole is not completely controlled: If the wheel of the cart that does not mount a rocking mechanism of the indicated type is braked or blocked, the movement achieved also incorporates a lateral turn; if, against said wheel, it can move freely, the cart can move uncontrollably because it is not predictable what the freewheel will do depending on, for example, the type of ground on which the cart is located; a very sliding floor would make it easier for the freewheel to move even more than the driven wheel, while if, for example, the cart is placed on a carpet, it is likely that only the wheel that receives the drive mechanism will move.

Explanation of the invention.

Based on the prior art, an objective of the present invention is to provide a device that drives the two rear wheels of a cart, independently or in combination, but in any case performing controlled movements on both wheels, which at the same time is adaptable to any car or baby chair, independent of the model or brand and that is quick and easy to place or uninstall for the user.

In order to achieve the proposed objectives, mentioned in the previous section, the invention proposes a device, which has the characteristics of claim 1.

Description of the drawings

To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:

Figure 1 shows a schematic view of the structure of a baby carriage (9) in which the device (10) of the invention has been placed.

Figure 2 represents a perspective view of said device (10).

As can be seen in the referenced figures, the rocking device (10) for baby carriages (9) is formed by a central housing (1) that integrates the drive and control mechanism of two shafts (2, 3) that protrude of it in opposite directions. This housing includes a two-way rotation mechanism, driven through a transmission by means of a drive motor whose rotation movements in both directions are commanded by a controller associated with an electric power battery of the motor itself.

The aforementioned axes (2, 3) are independent and can rotate in the same direction or in opposite directions, all depending on the control of the drive mechanism included in the housing (1), which has programming means for controlled movement sequences optionally through a computer application that interacts with the device controller allowing multiple advanced options, such as that it emits music or sounds audible by the baby, or match their movements with music or sound.

At the end, the respective axles (2, 3) mount two wheels (4, 5) that act as a means of transmitting the movement to the two rear wheels of the cart (9). These wheels (4, 5) incorporate a finish with a high friction rate that manages to drag the wheels of the cart even when it is located on rough ground or in which a certain torque is required to achieve the movement of the same.

This device also has two fixing means (6) to the trolley frame (9) in an area close to the wheels on which this mechanism is applied. Preferably these fixing means (6) to the trolley frame are clamps or other means that allow adjustment in order to fit the diameter of the trolley frame (9).

In a preferred embodiment, several means are provided that allow this device (10) to be adapted to any cart model (9). To this end, it is first provided that the axles (2, 3) are mounted telescopically on individual cylinders (7, 8) fixed in the housing (1), which allow the separation between the drive wheels (4, 5) to be regulated. ) so that the wheels (4, 5) always coincide on top of the rear wheels of the cart, regardless of the distance between them. Likewise, it is provided that the fixing means (6) to the trolley frame are mounted on the cylinders (7, 8) through a means that allows their movement along them, in order to regulate the

distance separating said fixing means and thus adapting to any frame model of the stroller.

In an advanced embodiment, the microcontroller that governs the movement of the cart is programmable or incorporates storage or communication means to receive operating routines, which can be programmed even by the user or sequentially follow any sound or music, which optionally can be reproduced in unison that moves by this equipment, or by a music equipment attached to it.

10 The equipment incorporates several interfaces for reprogramming or for other purposes; as well as a feeder for recharging the internal battery, from the common mains.

Once the nature of the invention has been described, as well as a preferred embodiment, it is evident that the invention is capable of industrial application in the indicated sector.

Likewise, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply an alteration of the essential characteristics of the invention claimed below:
