Description

Childcare device with seat.

The scope of the invention is that of the childcare, and in particular that of childcare devices  in which a child can be installed in a sitting position, such as child seat cars, or loungers. More precisely, the invention relates to a tilt and angle hammock childcare device Variable seat base depending on its inclination.

Many are already known chair-cars with hammock, or carrycot, tiltable. Classically, the hammock is mounted on the frame of the car-chair and on the frame are provided various means to guide, position and keep the hammock in position in the desired position.

An example of a car-chair from this type is presented in document FR-2 761 327, which belongs to the holder of this application for patent.

The owner of this patent application He has proposed an improvement. This is especially described in the EP-A-0 931 710 and consists in varying the opening angle of the base of the seat of the hammock, depending on its inclination.

So, when the hammock is in position straightened (sitting position), the angle formed by the element Seat base and hammock backrest, or angle of the base of the seat, it is of the order of 110º, so that it forms a chair, with backrest. Conversely, when the hammock is in position extended, the angle formed by the base of the hammock seat it opens a lot (of the order of 160º). In this way, the child is left comfortably sitting when the hammock is in the position of sitting, and lying, when the hammock is in an extended position. Naturally, intermediate positions may be provided.

To obtain this result, the hammock presents, Side view, a deformable triangle structure. The hypotenuse of this triangle is formed by the armor of the hammock. The other two sides (seat base part and part of backrest) are two stiffening elements (classically plates of plastic material) articulated in its common vertex. Armor It is designed so that its length can vary. Variations  of this length automatically involve opening or closing of the angle formed by the base part of the seat and the part of back.

More precisely, in sitting position, the armor has a minimum length, and in extended position, a maximum length. For this, the armor is conceived in two parts, an upper part and a lower part, the part being able upper penetrate telescopically into a portion of the part lower.

This telescopy is very effective in theory. Without However, in practice it poses numerous problems. Needs a Very precise adjustment, and remains unreliable over time. The younger defect, the least deformation and / or the smallest foreign body can disturb, even block, the relative movement of a part with Regarding the other.

Another example of a system that implements a telescopic structure is described in the document US-4 272 100. This also involves armor complex that presents the same drawbacks.

Moreover, the maintenance of the hammock in a given inclination, and with the opening of the angle of the base of the desired seat, can be secured through a set of solidarity cranks of the frame of the car-chair. A Such a mechanism is, however, relatively complex, both as regards its assembly, during the manufacture of the car-chair, as to its use. In particular, This is considered very impractical in the case where the hammock is intended to be used alternately in position sitting looking at the street and in sitting position looking at the mother.

More generally, known systems they present numerous drawbacks, both as regards their manufacturing:

-

number important moving parts;

-

weather important assembly,

as regards its use:

-

easy handling;

-

hammock difficulties reversible (position facing the street and position facing the mother);

-

security problems, due to the fact that the child can act on the regulatory elements of the inclination.

In the aforementioned patent document, it has been proposed an improvement, according to which the hammock comprises, on each of its sides, a piece of solidarity guide of one of the cited parts of the armor and presenting an oblong hole to through which a solitary guide pin of the other part circulates of the armor, allowing the displacement of the aforementioned bumper of guide through the said oblong hole control the said length of the armor and the inclination of said hammock.

Thus, the means that ensure and control the positioning and opening of the seat base angle are only solidarity with the hammock (and therefore independent of the frame). The guide piece is monobloc, and can be manufactured and easily mounted on the car seat. The cost of manufacturing is therefore reduced, with respect to techniques known.

However, despite the notable improvement that provides this solution with respect to previous techniques, the other inconveniences remain.

Indeed, difficulties persist during assembly assembly, especially due to precise adjustment to which is necessary to proceed to obtain a functioning satisfactory.

In addition, as already mentioned, the principle of the armor composed of two pieces that can slide one with Regarding the other, it regularly generates problems: the pieces Sliders wear out and / or get clogged, which can lead to mechanism locks, to the point of manipulation of the hammock painful, if not impossible, for the user.

In addition, a car-chair of this type is still relatively expensive to manufacture and assemble.

The invention aims especially to alleviate these different drawbacks of the state of the art.

More precisely, a first objective of the invention is to provide a childcare, hammock device tilt and opening angle of the base of the variable seat, which be more reliable and simpler than technical devices known.

Thus, the invention aims at, especially facilitate a device of this type in which the hammock tilt mechanism and angle variation of the base of the seat is not subject, or little, to the phenomena lock

The invention also aims at facilitate such a device, in which the cost of manufacturing is less, with respect to Classic chair cars of the same type.

More precisely, the invention has for aim to facilitate such a device, in which the cost of manufacturing, as well as the cost of assembly are reduced. In In particular, an object of the invention is to provide a device of this type in which the inclination and control of the angle of the seat base are secured by a number of pieces reduced.

Another object of the invention is to facilitate a device of this type, in which the hammock can be put in the desired position simply and safely, preferably by a person who stays at the back of the car-chair, and without the child's turn Interact on this position.

Still another object of the invention is retain the advantages of the solution described in the document EP-A-0 931 710 and, especially:

-

easy consolidation / solidarity the hammock with respect to the frame of the car-chair;

-

hammock reversible, without heavy and complex manipulations;

-

easy use of optional equipment Solidarity of the hammock.

These goals, as well as others that will be set manifest in what follows are achieved thanks to the invention that It is intended for a hammock according to claim 1.

A childcare device is thus obtained of tilting hammock and opening angle of the seat base variable, more reliable and simpler than technical devices known.

Indeed, the tilt mechanism of the hammock and variation of the angle of the seat base does not put on practice the classic principle of an armor composed of two Sliding pieces with respect to each other. They are avoided, by therefore, the inconveniences linked to this principle, namely risks of blocking or malfunction due to deformation or wear of the sliding parts or the presence between them of strange bodies.

In addition, difficulties are also avoided linked to the assembly and adjustment of sliding parts.

According to a preferred solution, the cited means of solidarity that can take at least two different positions are associated with the support of the mentioned seat.

Preferably, said means of solidarity are linked to the aforementioned part of the seat by a union of sliding pivot type.

Advantageously, said armor is mounted in the other of the mentioned parts of the seat with the help of a pivot joint and the length of the armor portion that is extends between said sliding pivot joint and said pivot joint is fixed.

Thus, it is clearly observed that the childcare device according to the invention looks free of any telescopic mechanism.

Of course, it can be considered, of course, integration into the device of telescopic parts, by example to proceed with the regulation of the position of a footrest or headrest. However, the operation of the hammock tilt mechanism and angle variation of the seat base is released from the resource anywhere telescopic, contrary to technical solutions previous.

According to the invention, said means of solidarity present at least one part that forms a housing for a cylindrical portion of said reinforcement 3, within which said cylindrical portion is mobile in rotation, and at least one part that forms a sliding plate, with respect at least one guide and / or maintenance element formed in the cited part of the seat.

The said sliding plate is, preferably, guided and / or maintained by two slides.

According to an advantageous solution, the aforementioned seat comprises means for regulating the position of the said means of solidarity with respect to the aforementioned part of the seat.

There are, thus, means that allow modify, according to different predetermined positions, the Tilt of the hammock and the angle of the seat base.

Preferably, the regulation means They comprise at least two emptyings.

Naturally, in other embodiments other means of regulation can be considered without leaving the framework of the invention and, especially, any type union Male female.

According to a preferred solution, the childcare device comprises means of blocking the said means of solidarity with respect to the aforementioned part of the seat. In this case, the said blocking means are operated, advantageously, at least for unlocking, by a single handle.

Preferably, said handle is mounted on the top of said backrest, so that allows the unlocking and control of the inclination of the mentioned Hammock, with one hand.

The device according to the invention is, thus, particularly simple and practical to use.

Advantageously, said handle is mounted on the aforementioned plate.

Preferably, said blocking means they include means of solicitation that automatically lead them to A locked position.

You get, thus, an indispensable security in the field of childcare, achieving this level of security thanks to automatic means that avoid proceeding to a succession of gestures by the user as is usually necessary with the classic solutions.

According to an advantageous solution, the aforementioned seat base is in solidarity with the aforementioned armor, free in rotation, in the vicinity of its free limb.

Advantageously, said armor defines a Closed perimeter essentially rectangular.

According to a preferred solution, said armature is pivotally mounted on said frame.

In this case, the device implements, preferably, two similar joint assemblies mounted on the cited frame and articulated with respect to the latter, being the aforementioned joint assemblies also pivotally mounted, on the one hand, in the mentioned armor and, on the other, at least in one of the aforementioned parts of the seat, such that the pivoting of said armor with respect to said frame modifies the angle between said base of seat 1 and said backrest.

Advantageously, said handle allows also control the regulation of said position armor with respect to said frame.

According to another characteristic, the aforementioned Hammock is reversible with respect to said frame.

According to an advantageous application of the invention, said hammock is a car-chair for boy.

The invention also relates to a childcare device comprising a hammock according to the invention.

Other features and advantages of the invention they will become clearer with the reading of the following description of an embodiment given by way of illustrative and non-limiting example, and the drawings, in which:

- Figures 1 and 2 are two views in perspective of a hammock according to the invention, in position sitting, respectively from front and back,

- Figures 2 and 3 are two views in perspective of a hammock according to the invention, in position lying down, respectively from the front and from behind;

- Figures 5 to 7 are views of the means of regulation that equip a hammock according to the invention.

The invention therefore presents a new solution that allows the angle to be varied efficiently and simply formed by the base of the seat and the backrest of a hammock for a childcare device.

In the following, a hammock of according to the invention, intended to equip a car-chair

It will be noted, however, that the invention It can be applied to other childcare devices, such as, especially, the sunbeds, the chairs, the seats of cars ...

Referring to figures 1 and 2, the hammock of a car-chair has a seat formed by a seat base 1 and a backrest 2, articulated one with respect to the another, such that the angle between the base of the seat and the backup can be modified between two configurations, one in the which child occupies a sitting position and the other in which It occupies an extended position.

A hammock of this type also includes a reinforcement 3 in which the base of the pivot is mounted seat and backrest as will be explained in the following.

This armor 3, which defines a perimeter essentially rectangular, it is intended, according to a mode of advantageous realization, to be in solidarity with the frame of a child car seat.

In accordance with the present embodiment of the invention, a cylindrical portion of the armature 3 is mobile housed in rotation in a 4-star housing of one plate 41, capable of sliding along slides 21 formed on the backrest 2.

The housing 4 and the plate 41 thus form means of solidarity that, according to the invention, can take different positions with respect to one of the parts of the seat (here the backrest), while occupying a fixed position with respect to armor 3.

This joint, of the sliding pivot type, allows to modify the angle between the base of the seat and the backrest,  and this without the need to resort to telescopic armor. It is observed, in effect, that the length of the armor portion, extending between the sliding pivot joint with the backrest and the pivot joint 31 with the seat base is fixed.

It is indicated that, according to other possible ways of realization, the means of solidarity that unite the armor 3 and backrest 2 could be equally, or alternatively, provided between the armor and the base of the seat.

The handle 5 is mounted on the part upper backrest 2, thus allowing the user to obtain the Unlocking and controlling the inclination of the hammock, with just one hand.

Figures 5 and 6 are views of means of adjustment of the position of the plate 41 and, therefore, of the accommodation 4, with respect to the backrest 2.

In figure 5, the device is in position locked, the handle 5 being in the rest position. He blocking is obtained through bolts 52 operated with the 521 stud support that can circulate through the holes inclined 511. The bolts 52 and the studs 521 are coupled each other in such a way that the displacement of the lugs causes the one with the locks.

In said position of the handle 5, these bolts 52 interact with the slides 411 so that block the slide of the plate 41 with respect to the backrest 2.

Naturally, in such a configuration, it is not possible to modify the inclination of the hammock or the angle of the seat base.

To obtain the unlocked position illustrated in Figure 6, the handle 5 is pulled upwards, which draws the lugs 521, which move through the holes 511, from the position they occupy in Figure 5 towards the position which they occupy in Figure 6. In other words, the lugs 511 move towards each other, so that they remove the bolts 52 from the slides 411. The plate 41 can then slide freely with respect to the
backup 2.

In this way, the hammock can be tilted and the angle of the seat base modified according to different Possible positions, obtaining the locked position in the desired position by simply relaxing the handle 5 that returns automatically to the position illustrated by figure 5 thanks to means of solicitation (not represented) to which it is coupled.

In addition, the position of the plate 41 along of the backrest 2 is regulated, that is to say that means are provided of regulation so that the plate 41 can occupy positions predetermined that correspond to as many inclinations other than the hammock.

To do this, the slides 411 of the plate 41 has 412 emptyings that form housings for the bolts 52.

Thus, acting on the handle 5 as indicated above, the bolts 52 are removed from one or the other of the 412, the plate 41 is moved along the backrest 2, and then, relaxing the handle 5, the bolts 52 are introduced in another 412 dump to ensure hammock blockage in a New default settings.

So, according to the operation that just described, it is understood that the handle allows, with one hand, unlock the plate with respect to the backrest, and then, keeping the handle pulled up, modify the inclination of the hammock as well as the angle of the base of the seat.

As indicated above, armor 3 is mounted, advantageously, on the frame of a child car seat, with the help of two junction assemblies 6 each having a recess 61 designed to accommodate a supportive element of the frame, of such so that the frame can pivot with respect to the frame of the car-chair

These joint assemblies are designed to be easily mounted and disassembled in the frame of the car-chair, either to orient the hammock by looking to the street or, conversely and reversibly, looking at the adult that pushes the car-chair.

In accordance with the present embodiment, the joint assemblies 6 are free in rotation with respect, for one part, to the reinforcement, with the help of pivot joints 62 and, on the other, with respect to the backrest 2, with the help of a union of pivot 63.

Thus, pivoting the armor with with respect to the frame automatically modifies the angle between the seat base 1 and backrest 2, as will be explained in detail in what follows.

It will now explain the operation that allows the modification of the inclination of the hammock with respect to the frame of the car-chair, as well as the angle between the seat base and the backrest.

Consider the hypothesis that armor and seat occupy a straightened starting position, illustrated by Figures 1 and 2, in which the child occupies a sitting position, and suppose that the user wishes to modify the position of the hammock to take the child to an extended position.

From this straightened position, the user actuates the handle 5, causing the release of the plate 41 with respect to backup 2 (as described above) and allowing the pivoting of the reinforcement 3 with respect to the frame of the car-chair (it will be observed nonetheless that unlocking the frame with respect to the frame may have been previously made by the user, with the help of complementary and / or independent controls).

Keeping the handle 5 operated, and accompanying it down, the user accompanies the tilt of the armor 3 towards a position such as that illustrated in the Figures 3 and 4.

During this movement, armor 3 rotates in the inside of its housing 4 while the plate 41 is moves along the slides 21 of the backrest 2, to go to a position such as that shown in figure 4.

Simultaneously, union assemblies 6 pivot around junction 62 with respect to the armor to go to gradually occupy a position in which they extend substantially along the armor 3, as it appears in the figure 3.

As this maneuver occurs, and thanks to the pivot joints 62, 63, 31 combined with the union of sliding pivot between the frame 3 and the backrest 2, the angle between the base of the seat 1 and the backrest 2 opens progressively, to finally occupy a position that allows the child being cast, as illustrated by figures 3 and 4.

It will be noted that points 4, 31, 7 and 63 define then a deformable quadrilateral, which allows the hammock regulation according to the invention.

The user then relaxes the handle 5, the which, thanks to its means of solicitation, causes the blocking of the hammock in the desired position.

Naturally, the user can, in any moment, relax the handle in an intermediate position, being facilitated by the presence of the means of regulation.

The transition from the extended position to the position sitting is obtained by proceeding in reverse order to the stages that They have just been described.
