Abstract

The folding frame has two main frame sections (11, 12) set at an angle to one another and held in the deployed position by a horizontal supporting frame (15). The frame section (12) has one bar forming a pivot for two parallel supporting legs of the frame section (11). The frame section is equipped with two coupling modules (13, 14), one forming the hinge for the pivot between the two main frame sections and the other a sliding and locking coupling for the supporting frame.

Description

The field of the invention is that of childcare. More specifically, the invention relates to the manufacture and production of children's furniture objects, such as playpens, changing tables, chairs, deckchairs, beds, ... More specifically, the invention relates to folding frames for such childcare objects.

By folding frame is meant a frame which can take a folded position, in which all of the elements which constitute it are brought as much as possible substantially in the same plane, in order to reduce its bulk, and at least one unfolded position in which the chassis rests stably on four feet, and serves as support for the elements defining the object in question (park walls, changing table, bath, chair, hammock, deckchair, bed, etc.).

Folding frames have been around for a long time in the field of childcare. Numerous known systems, based in particular on joints, hinges, links, return means, etc. It is enough to consult catalogs in the field to see that, for each piece of childcare furniture, solutions adapted to specific needs of the object concerned have been proposed.

Thus, for example, playpens, changing tables and baths can exploit a double symmetry (in relation to the length and width of the object) to allow efficient folding.

In the case of high chairs, there is generally provided a rear frame element, corresponding to the rear legs, on which is articulated a second frame element corresponding to the front legs. Two joints are provided, one on each of the rear legs, substantially at the level of the attachment of the seat itself.

In general, known folding frames are complex to build, and require a high number of parts, meticulous assembly (for example, to articulate the front and rear legs of a high chair using two small axes whose precise positioning is not easy).

In addition, these known techniques assume a specific manufacturing for each object of furniture.

The invention particularly aims to overcome these drawbacks of the state of the art.

More specifically, the objective of the invention is to provide a new technique for manufacturing folding frames for childcare furniture objects.

• fournir des châssis pliants plus simples à fabriquer et à monter que les châssis pliants de types connus ;
• fournir des châssis pliants formés par un nombre de pièces limité et simples à réaliser ;
• fournir un châssis pliant, et plus généralement un objet de mobilier correspondant, qui soit d'un coût réduit, sans que cela nuise à ses autres qualités (facilité d'utilisation, solidité, fiabilité, sécurité,...);
• fournir un nouveau type de châssis, qui permette de développer de nouveaux aspects esthétiques pour le mobilier pour enfants.

This general objective notably includes the following specific sub-objectives:

• provide folding frames simpler to manufacture and assemble than folding frames of known types;
• supplying folding frames formed by a limited number of parts and simple to make;
• provide a folding frame, and more generally a corresponding item of furniture, which is of reduced cost, without affecting its other qualities (ease of use, solidity, reliability, security, ...);
• provide a new type of frame, which allows to develop new aesthetic aspects for children's furniture.

• un premier module de liaison, dit module en π, monté sur ladite portion du second élément de châssis formant axe d'articulation et recevant une extrémité de chacune desdites portions parallèles du premier élément de châssis ; et
• un second module de liaison, dit module en H, perpendiculaire auxdites portions parallèles du premier élément de châssis, pouvant coulisser le long desdites portions parallèles et portant une extrémité de chacun des desdits éléments de maintien.

These objectives, as well as others which will appear subsequently, are achieved according to the invention with the aid of a folding chassis for childcare furniture object, comprising a first and a second chassis elements, respectively defining a first and a second plane and substantially forming a triangle articulated at one of its vertices, held in the unfolded position by means of at least one element forming a retaining rod, said second frame element having a portion forming an axis of articulation , and the first frame element having two portions parallel to each other and perpendicular to said axis of articulation, and comprising two connection modules:

• a first connection module, said module in π, mounted on said portion of the second frame member forming a hinge pin and receiving one end of each of said parallel portions of the first frame member; and
• a second connection module, said H-module, perpendicular to said parallel portions of the first frame element, which can slide along said parallel portions and carrying one end of each of said holding elements.

A particularly simple chassis is thus obtained, and allowing the production of a large number of childcare objects, from the same basic system. The assembly is very simple, the number of parts being reduced.

• les parcs pour enfant ;
• les tables à langer et/ou baignoires pour enfant ;
• les lits pour enfant ;
• les chaises pour enfant, et notamment les chaises hautes ;

Such a folding frame can in particular be intended for at least one of the objects belonging to the group comprising:

• children's playpens;
• changing tables and / or baths for children;
• children's beds;
• children's chairs, including high chairs;
• children's chairs of the deckchair type.

According to a preferred embodiment of the invention, said connection modules are produced in the form of two complementary half-shells, secured during assembly.

The manufacture of these modules is then easy (for example by molding), as is the assembly and assembly.

The invention relates in particular to a playpen comprising such a folding frame, and in which said holding element forms a lower frame. Such a park in particular comprises an upper frame extending parallel to said lower frame, in the unfolded position, a net forming the walls of said park being stretched between said lower and upper frames.

Advantageously, said upper frame is articulated on said portion forming an axis of articulation of the second chassis element, and maintained in the deployed position using at least one link connecting said upper frame and said second chassis element.

The invention also relates to a changing table comprising such a folding frame, and comprising an upper frame extending parallel to said frame. lower, in the unfolded position, designed to receive a changing tray and / or a bathtub.

Preferably, said changing tray is equipped with holding pads, cooperating with said upper frame and, if necessary, with another support.

Thus, for example, the tray can also be used on another support, such as a bed. Advantageously, in this case, the position of at least some of the holding pads can be adjustable.

The invention also relates to a high chair comprising such a folding frame. It includes in particular an upper frame extending parallel to said lower frame, in the unfolded position, designed to receive a tablet.

According to an advantageous embodiment, said upper frame is pivotally mounted with respect to an axis passing through said first chassis element, so that it can assume a shelf support position, by coming to bear on stops provided for this effect on said second frame member, and a withdrawn position, behind said first frame member. It can also be removable.

Preferably, such a high chair comprises a first cross connecting the uprights of said first frame member and a second cross connecting the amounts of said second chassis member, said cross cooperating with support means of the seat of said high chair.

The invention also relates to a deckchair comprising such a folding frame, said first frame member extending substantially parallel to the ground, and said second frame member supporting the hammock of said deckchair.

According to an advantageous embodiment of the invention, for such a deckchair, said H-link module can take at least two distinct stable positions along said first frame element, corresponding to different inclinations of said deckchair.

Preferably, a support piece for the seat of said hammock, integral with said elements forming holding rods, is provided, so that the angle between the seat and the back of said hammock varies as a function of the inclination of the deckchair.

The invention therefore relates to a new chassis for childcare furniture objects. The general principle of this chassis is illustrated by FIGS. 1A and 1B.

FIG. 1A shows, seen from the side, the frame elements common to all the pieces of furniture. The specific complementary aspects are discussed below, in relation to the corresponding figures. Figure 1B illustrates the chassis of FIG. 1A seen from behind. It is clear that, in these FIGS. 1A and 1B, the scales and the size ratios between the different parts are not necessarily observed.

A chassis according to the invention therefore comprises a first chassis element 11 and a second chassis element 12. These two chassis elements 11 and 12 are articulated at one of their ends by means of a first connection module 13.

A second connection module 14 is provided, which can slide on the first frame element 11. It is integral with at least one link 15 (conventionally, for reasons of symmetry, a link is provided on each of the sides of the frame, or a single piece comprising the two links, for example forming a "U" or a complete frame). These links are pivotally mounted on the second chassis element 12 at their other end.

Thus, in the unfolded position, the basic elements of the chassis substantially define an "A" profile (FIG. 1A).

During folding, the second connection module 14 slides along the first chassis element 11 towards the first connection module 13 (or in the opposite direction). The link 15 and the first connection module 13 then bring the second frame element 12 back into the plane of the first element 11.

Preferably, the frame elements 11 and 12 are substantially curved, and not conventionally rectilinear. In addition to the new aesthetic appearance, this allows in particular the second frame element 12 to provide effective support and maintenance of the specific elements of the piece of furniture concerned.

Furthermore, this curved line makes it possible to define a neutral point, which can form anti-folding security (for example, in the case of the high chair described below, it is not possible to fold the chair involuntarily by acting on the ends of the legs (as a child could do on the front legs, the rear legs being held against a wall. In the absence of this neutral position, additional security would be necessary.

In addition, this shape provides greater stability than simple straight legs.

It will also be noted, as it appears clearly in FIG. 1B, that the spacing between the uprights 111 and 112 of the first chassis element 11 is very small compared to the spacing between the uprights 121 and 122 of the second chassis element. The second element of the chassis 12 must indeed be able to receive a hammock, a bathtub, the walls of a playpen, ...

The uprights 111 and 112 are in turn provided to cooperate with the two connection modules 13 and 14. To ensure stability, they end with feet 113 and 114 spaced apart extending parallel to the ground.

Advantageously, the first frame element 11 is formed of two independent and identical uprights. The second chassis element 12 can in turn be produced in a single piece, the intermediate portion 123 of which forms the axis of articulation of the chassis. These two chassis elements 11 and 12 are for example produced using tubular parts, according to conventional techniques.

In most cases, the chassis will be used in the position illustrated in Figure 1A. It is clear however that it can be tilted (the first element 11 then being substantially horizontal) without departing from the scope of the invention. This is for example the case of the deckchair described below.

FIGS. 2A and 2B show a structure (that is to say essentially the chassis and certain constituent elements, but not the covering, the finishing or the optional elements) of a changing table according to the invention.

We recognize, in Figure 2A, the first frame element 11 and the second element 12 which define the four legs 21 ₁ to 21 ₄ of the table. The first connection module (module in π) 13 is mounted on the intermediate part 123 of the second chassis element, and can pivot on this axis. It also maintains the two uprights 111 and 112 of the first frame element 11.

The second connection module (H-module) 14 is slidably mounted on the two uprights 111 and 112. It also maintains a frame 22, which is also connected to the uprights 121 and 122 by means of two axes 23 ₁ and 23 ₂ around which it can rotate.

This frame 22 therefore plays the role of the rods 15 described above. It can also serve as a support for example to a tablet.

The second connection module 14 is stopped in the desired position (frame 22 in horizontal position) using a stop 213, which advantageously extends between the two uprights 111 and 112.

The chassis also comprises a second frame 24 which can receive a changing tray and / or a bathtub. This frame 24 is mounted articulated on the intermediate part 123 of the second chassis element, by means of two hinges 25 ₁ and 25 ₂ .

In the unfolded position, this frame 24 extends in a horizontal upper position. It is held in this position by means of two rods 26 ₁ and 26 ₂ , one of the ends of which is pivotally mounted on the upright 121, 122, by means of an axis 27 ₁ , 27 ₂ and the l 'other end can slide on the frame 24, by means of a slide 28 ₁ , 28 ₂ which carries an axis around which the end of the link can pivot. A stop 29 ₁ , 29 ₂ is provided, which corresponds to the appropriate position of the frame 24 in the unfolded position.

It will be noted that, due to the curved shape of the uprights, the links 26 ₁ and 26 ₂ also play a safety function. They have a neutral point, which prevents any inadvertent tilting of the upper part.

The bathtub or changing tray 210 can be removable. In the case of the changing table in particular, it can also be mounted articulated on the frame 24.

The illustrated changing tray has two holding hoops 211 ₁ , 211 ₂ intended to prevent the child from falling, and allowing the carrying of the tray. It is easily and stably positioned on the frame 24 thanks to the presence of studs 212 which come into contact with the inside and / or the outside of the frame 24.

Other fixing systems can also be provided. Note also that several studs can be installed, so as to allow the reusing the changing pad on another piece of furniture, such as a bed, even if the dimensions are not exactly the same as those on the changing table. It can also be provided that the position of at least some of the studs is adjustable.

In the folded position (Figure 2B), the chassis is brought back in one plane. The H-link module 14 slid towards the π-link module 13, along the uprights 111 and 112. It entrained the lower frame 22, which pivoted along the axes 23 ₁ and 23 ₂ . Initially, the slides 28 ₁ and 28 ₂ were brought back to the intermediate part 123, so as to bring the upper frame 24 in the same plane as that defined by the uprights 121 and 122, under the action of the rods 26 ₁ and 26 ₂ .

FIGS. 3A and 3B show the folding frame of a playpen according to the invention. The basic principle of this chassis is very close to that described above for the changing table.

We therefore do not re-describe all of the elements again, but only emphasize the few specific aspects.

The lower frame 22 carries the floor 31 of the park. For this reason, this frame is placed lower than that of the changing table. This floor can be secured to the frame 22 by one or more hooks 34.

The walls of the playpen (not shown) are conventionally formed by a flexible net, or a similar element, stretched between the lower frame 22 and the upper frame 24.

The rods 26 ₁ and 26 ₂ for holding the upper frame 24 are pivotally mounted on the frame 24 (axes 32 ₁ and 32 ₂ ). This frame 24 also serves as a support for the holding arch or the handrail which will be mounted on the park. He could also form this handrail himself.

The slides 28 ₁ and 28 ₂ are therefore in turn mounted on the uprights 121 and 122. Similarly, the stops 33 ₁ and 33 ₂ are then formed on these uprights 121 and 122. It is thus shown, between Figures 2A and 3A , that the two modes of realization are possible, whether for one or the other of the objects of furniture.

Furthermore, one can provide a hook 35, which keeps the park in the folded position, securing the floor to an element of the frame.

Figure 3B illustrates the frame of Figure 3A in the folded position. The folding is obtained in the same way as that which has been described in relation to FIG. 2B. Again, we see that the chassis then extends substantially in the same plane, and has a very small footprint.

Figure 4A shows a high chair according to the invention. Again, we recognize the first chassis element 11 and the second chassis element 12 articulated on the module in π 13, as well as the module in H 14, sliding on the uprights 111 and 112 and carrying the lower frame 22. In position unfolded, this frame extends substantially horizontally. The H 14 connection module is held in position by a stop 213 extending between the two uprights 111 and 112.

An upper frame 41 is also provided. However, unlike the two objects described above, it does not extend at the level of the upper part of the chassis (that is to say at the level of the connecting element 13), but at an intermediate position. This upper frame is in fact provided to hold the seat (not shown) and to receive a tablet (also not shown). It is advantageously removable.

This frame 41 is pivotally mounted on an axis 42 connecting the two uprights 111 and 112, and perpendicular to the latter. The elements forming the articulation advantageously comprise two clipped modules 46 ₁ and 46 ₂ (FIG. 4B), which allow the separation of the frame and the chassis.

It also rests on two pins 43 ₁ and 43 ₂ provided for this purpose on the uprights 121 and 122 of the second element of the chassis 12. The position of these pins 43 ₁ and 43 ₂ is provided so that when the chair is in position unfolded, the upper frame is substantially horizontal.

Advantageously, a cross member 44 is also provided extending between the two uprights 121 and 122, perpendicular to the latter, at the level of the seat. from the headquarters. A strap 45 can be placed between the crosspiece 44 and the axis 42 to maintain the seat in the desired position. The length of this strap can be adjustable.

The seat can be equipped with various safety and support elements (such as a belt or harness, a booster element, etc.). The seat can advantageously take several successive forms, so as to be adapted to the different ages of a child. For this purpose, the frame 41 can be tilted so as to be brought back along the first frame element, even when the chair is unfolded.

Furthermore, the tablet is advantageously removable and designed so as to be able to take several positions on the frame 41.

Figure 4B illustrates the chair of Figure 4A in the folded position. First of all, the frame 41 was brought to the rear of the assembly, along the first frame element 11, then the connection module 14 was slid towards the connection module 21, so that the frame lower 22 brings the second chassis element 12 in the same plane as the first chassis element 11.

Figures 5A and 5B show the folding frame of a deckchair according to the invention. In this embodiment, the arrangement of the elements is slightly modified, although the construction of the chassis itself remains similar to that already described. Indeed, the chassis has been "tilted" by 90 °, the first chassis element 11 now being in the lower position.

Compared to the objects already described, it can be seen that there is not here the equivalent of the upper frame 21. In fact, the hammock of the deckchair bears directly on the second frame element 12.

Furthermore, the lower frame 22 is replaced by a U-shaped part 51, the two parallel branches 511 and 512 of which play the role of the links already described and the intermediate part 513 of which is integral with the H 14 connection module. Advantageously, this intermediate part 513 flows under the first frame element 11. The upper ends of the link elements 511 and 512 carry an element (for example, a rigid metal wire) which defines the outline of the seat of the hammock.

The principle of folding is the same as that described above. The connecting module 14 is moved along the uprights 111 and 112, to bring the second chassis element 12 in the same plane as the first chassis element 11. However, in the case of the deckchair, folding is obtained by moving the link module 14 of link module 13, as shown in FIG. 5B.

Note also that one can provide several stable positions for the connecting module 14 along the first frame member 11 which correspond to several possible inclinations of the deckchair. Several techniques can be envisaged to define these different positions. An advantageous technique is notably described in a joint patent application filed in the name of the same Applicant and having as its title "Device for adjusting the inclination of a child's chair, and corresponding chair".

In this case, we see that the different inclination positions act independently on the second frame element (which corresponds to the back of the hammock), and on parts 511 and 512, and therefore on the wire 52 (which corresponds to the seat of the hammock). Consequently, it is possible to obtain an opening angle between the backrest and the variable seat according to the inclination chosen.

As indicated above, the invention advantageously makes it possible to reuse the same connection modules for several different chassis. In addition to an interesting range effect, this of course allows economies of scale.

According to an advantageous embodiment, these connection modules are produced in the form of two half-shells, for example made of plastic, which are placed on the chassis elements before joining them together.

FIG. 6 illustrates the internal structure of a half-shell of the first connection module (module in π) according to the invention. This module is called module in π because the chassis elements with which it cooperates define approximately this letter.

It comprises two openings 61 and 62 allowing the passage of the intermediate part 123 of the second chassis element. Ribs 63 ₁ to 63 ₆ ensure the correct positioning of the module with respect to this intermediate element 123, and therefore an adjusted articulation of the two chassis elements.

Furthermore, it has two other openings 64 and 65, for each of the uprights 111 and 112 of the first chassis element 11. These uprights are positioned FIG. 7 illustrates the second connection module (H-module) according to the invention. This module is called an H module because the chassis elements with which it cooperates define approximately this letter.

It comprises four openings 71 ₁ , 71 ₂ , 72 ₁ , 72 ₂ respectively receiving the uprights 111 and 112, and allowing the module to slide in H along the latter. Two other openings 73 and 74 receive part of the lower frame 22 (or of the U-shaped part 51). The module in H is designed so that a rotation is possible around this part which crosses it.

As for the module in π, ribs are provided for the proper positioning of the different elements.

FIG. 8 very schematically illustrates the method of manufacturing different types of chassis that makes it possible to envisage the chassis structure of the invention.

• pièces propres à la table à langer (81) ;
• pièces propres au parc (82) ;
• pièces propres à la chaise haute (83) ;
• pièces propres au transat (84) ;
• ...

According to this process, each specific part of each chassis is specifically produced, for example:

• parts specific to the changing table (81);
• park-specific rooms (82);
• parts specific to the high chair (83);
• parts specific to the deckchair (84);
• ...

Furthermore, the first connection module (85) and the second connection module (86) are produced for all of these chassis on the one hand.

From these two sources, we can mount each of these frames, then the complete object (87 to 810).

This process can also be used by trivializing other aspects than the mere production of the connection modules. Indeed, other parts can be found at the same on several elements. Furthermore, the use of the same basic material (tubes forming the frame) is also possible.

In addition to the four pieces of furniture described in the invention, it is clear that this technique allows other objects of furniture to be produced, such as a folding bed, a chest of drawers, etc.
