Abstract

THE PLATFORM, INCLUDING A BOTTOM 8 AND A SIDE SKIRT 9 FOR CONNECTING THE BOTTOM WITH THE UPPER PERIPHERAL EDGE 10 FOR SUPPORT AND FIXING OF THE PLATFORM, IS CHARACTERIZED BY THE FACT THAT THE BOTTOM 8 IS DEFORMABLE FOLLOWING AT LEAST ONE HINGE LINE TRANSVERSALE 12 AND THAT RETAINING MEANS 13 ARE PROVIDED TO VARY LOCALLY THE ACTIVE HEIGHT OF THE SKIRT, ON EACH SIDE OF THE PLATFORM, FROM THE SAID EDGE, AT AT LEAST ONE POINT, AND PREFERABLY AT AT LEAST TWO POINTS LOCATED ON EACH OTHER OF THE SAID LINE OF ARTICULATION 12, THE ASSEMBLY BEING SUCH AS, ON THE ONE HAND, WHEN THE RETAINING MEANS ARE FREE, THE SKIRT OCCUPIES ITS MAXIMUM ACTIVE HEIGHT AND THE BOTTOM IS DEPLOYED SENSITIVELY FLAT FOR OBTAINING THE "BED" POSITION AND THAT, ON THE OTHER HAND, WHEN THESE RETAINING MEANS ARE IMPLEMENTED, THEY LOCALLY RAISE THE BOTTOM IN RELATION TO THE EDGE.

Description

The invention relates to nacelles intended to

to have a child.

  It applies in particular, but not

  restrictive, to nacelles which are intended to equip the vehicles

  children's tures, especially folding strollers. Currently, depending on whether you want to lay the child flat or put him in a seated position, you must have two pieces of equipment: an actual cradle, that is to say a kind of bed, with a substantially flat bottom and a seat which includes a backrest and a seat inclined one

compared to each other.

  This obligation entails various drawbacks as to the space required for the storage of the equipment when it is not in use, as to the cost since it is necessary to acquire two pieces of equipment, and as to the handling; on this last point, or else the two pieces of equipment are intended to be mounted

  on a single common support, for example the chassis of a push

  sette, which requires dismantling one piece of equipment from the support and replacing it with the other, the first piece of equipment then having to be stored, or else these pieces of equipment each have their own

  own support, which nevertheless requires storage operations

is lying.

  In the particular case of strollers, the replacement

  one equipment by the other is only possible at home or, in general, only in a place where both equipment is available at the same time, for example near a motor vehicle if you have taken the precaution to bring both equipments; in no case is it possible for the mother, during displacement, to make this replacement since she then has only the only equipment mounted on the stroller,

  which prevents him from moving the child from the as-

  normal seat in the perfectly reclining position, and vice versa.

  We have already proposed the solution which consists of a seat

  variable tilt age but, in this case, the extended position

  is not comfortable for the child since he must stay

  on his back, his legs being bent.

  The object of the invention is to remedy these drawbacks

  by providing basket type equipment that can easily-

  ment go from the "bed" state, to the "seat" state, and vice versa, the two positions being very comfortable and natural for the child. To this end, the nacelle according to the invention, comprising a bottom and a lateral skirt for connecting the bottom with the upper peripheral edge for supporting and fixing the

  nacelle, is characterized by the fact that the bottom is deformed

  ble following at least one transverse articulation line and

  that retaining means are provided to vary local-

  the active height of the skirt, on each side of the carrycot

  from said border, at least one point, and preferably

  at least two points located on either side of the

  said articulation line, the assembly being such that, on the one hand, when the retaining means are released, the skirt occupies its maximum active height and the bottom is deployed substantially flat to obtain the "bed" position "and that, on the other hand, when these retaining means are used, they raise the bottom locally with respect to the edge, so that the bottom bends and defines a backrest and a seat for obtaining

from the "seat" position.

  The transverse articulation line of the bottom corresponds to

  lays at the junction between the backrest and the seat for the seat position. Preferably, the bottom is also deformable along a second transverse articulation line corresponding to the front edge of the seat for the seat position so that the bottom

  has, for this position, an extreme front surface, inclined

  born in relation to the seat, to support the lower part

of the child's legs.

  In the specific application for reversible strollers

  sibles, the nacelle is symmetrical, as for its skirt and its bottom,

  and preferably also with regard to the retaining means with respect to

  port to a transverse plane to be able to be put in position "facing the mother" or "facing the road" by simple tilting around a transverse axis without turning the bottom face to

  face, so that the basket can, for each in its posi-

  seat and bed, be oriented in the direction of travel or

In the opposite way.

  The nacelle may include means for retracting excess material from the skirt for the seat position. These retraction means are for example constituted by a bellows or a fold containing said excess and closed by suitable means (buttoning, zipper, hooking, lacing, hook-and-loop fastening, straps, etc.), or else this excess is picked up on itself, against the skirt and / or

  against the underside or exterior of the bottom of the nacelle.

  Where appropriate, the retaining means and the retracting means may be common, for example if recourse is had

  to straps or the like, hook-and-loop, with a buckle

  ture or knotting, or if using zippers, to both decrease the active height of the skirt

  and retract the excess thereof for the seat position.

  Advantageously, the bottom comprises means of rai-

  built-in reinforcement, for example in the form of slats or

  plates, sparing the transverse joint (s)

  above. These stiffening means, while being constituted

  by a relatively rigid material, for example polypropy-

  lene a few millimeters thick, nevertheless give the bottom a certain overall flexibility, for example by lines of weakness or by a spacing of said means of

  stiffening. In the particular case of application to pushers

  folding folds, and although this feature is useful

  sand in other applications than that of strollers, the bottom has at least one longitudinal articulation line so that the basket can be folded back on itself

  around this longitudinal joint.

  According to a particular embodiment, the bottom comprises separate stiffening plates whose adjacent edges are parallel, these plates being taken between two thicknesses of fabric or the like and being held in place by seam lines or the like extending between said edges adjacent

  plates to define immobilization gussets of this

  these. According to another characteristic of the invention, the upper edge of the nacelle is subject to two beams

  connected by end crosspieces, central handles

  trales being provided so that the carrycot can be removed from its support and used as a baby carrier. Where appropriate, in the application to folding strollers of the "bundle" type, in which the stroller is folded back on itself also in the

  transverse direction, the crosspieces can be removable or deformed

  tables so that this lateral folding is possible.

  The invention will be clearly understood on reading the

  description which follows and with reference to the accompanying drawings

wherein:

according to a variant.

  FIGS. 1 to 4 show a nacelle 1 intended to receive

a child.

  In the preferred application of the invention, the nacelle 1 is

  mounted on the chassis 2 of a stroller, for example of the "cane" type,

  both arms 3 with their handle 4, a front base 5 carrying front wheels (not shown), and a rear base 6 carrying rear wheels

(also not shown). -

  The nacelle 1 is mounted on the chassis 2 using nuts 7 per-

  putting the adjustment of its angular position and its blocking.

  The nacelle 1 has a bottom 8 and a side skirt

  9 connecting the bottom 8 with the upper peripheral border

  lower 10 for mounting the nacelle on the chassis 2 via the

  medial of the nuts 7. In practice, the upper edge of the skirt 9 is received, on each side, by a support beam 11 (FIG. 9),

  as for example by means of mounting tabs and / or a tubular hem

  laire. The rails are either part of a frame (Figure 9) or

  are parallel and independent (Figure 10).

  The skirt 9 is made of a flexible or deformable material, for example canvas. It has, on each side, a panel which in height extends from the edge 10 to its

connection with the bottom 8.

  The bottom 8 extends over the entire length of the nacel-

  it to connect the two small transverse sides of it.

  The bottom 8 is deformable along a line of articulation.

  transverse lation 12 and retaining means 13 are provided for locally varying the active height of the skirt, on each side of the nacelle, from the edge; as seen in Figures I to 4, such means 13 are planned to

  on either side of the hinge line 12.

  In the embodiment shown, these means of rete-

  naked 13 are formed by clean straps to come overlapping-

  dear border 10 in their active position. The rear straps

  re 13 are fixed at one end to the outside of

  the nacelle, at the junction between the skirt and the bottom.

  At their other end, they carry a button or

  analog 14 which can come to cooperate with a complementary organ

  keep quiet 15, for example a counter-button, at an appropriate height on the inside of the skirt (Figure 3). The front straps 13 are fixed, at one end, to the interior face of the nacelle, at the junction between the skirt and the bottom and in the vicinity of the front edge of the seat. At their other end, they carry a button or the like 16 which can cooperate with a complementary member 17, for example a counter-button, provided on the

  outer face of the skirt, just below the border 10.

  Alternatively, one could arrange the two pairs of straps 13 in the same way, for example like the front straps. As

  another variant, the straps could be of the self-adhesive ribbons type

  grips, or be replaced by zippers 18,

  shown schematically and partially in Figure 4.

  It appears from the above and from an examination of the figures

  gures 1 to 4 that, thanks to the articulation 12 and the means for varying the active height of the skirt, it is possible to give the nacelle according to the invention a bed position (Figures 2 and 4), for which the bottom 8 is substantially flat and the skirt 9 is deployed, and a seat position (Figures 1 and 3) for which

  the bottom is bent around line 12 and the skirt is localized

  slightly raised, which accompanies and / or causes the ascent

local from bottom to border 10.

  For the seat position, the nacelle has, by its bottom 8, a back part 8a and a seat part 8b inclined with respect to each other and connecting along

from line 12.

  When the front straps 13 are used, the bottom 8 is raised in its part 8b to define the seat, the rear straps 13 can also be used

  to obtain an open seat (Figure 1), either be left

  inactive to obtain a laterally protected seat in the upper part of the backrest 8b (Figure 3). If necessary, rear straps 13 or the like could be dispensed with, the nacelle then remaining laterally protected for the seat position. The nacelle can advantageously be completed by a protective cover 19, shown only in FIGS. 1 and 2,

  which can be used for both positions.

  For the bed position, the platform is put in the normal horizontal position while for the seat position, it

  can be placed in any desired angular position.

  Because, for the seat position, the skirt locally has an active height less than that which it has for the bed position, there is, for the seat position, a local excess of material which normally constitutes folds 20

  (Figures 1 and 3) establishing themselves randomly.

  According to a characteristic of the invention, one pre-

  sees means for retracting this excess material. For example, these means may consist of a bellows, a false pocket or an appropriately closed fold, in particular

  by buttoning, zipper, hooking, lacing, iron-

  hook-and-loop fastening, etc. As an example, we have shown

  felt on the fioure 1 two bellows or zip fasteners 21 on the underside of the bottom 8, these means can however belong to the retaining nyens 13. For example, the straps 13 can extend on the outside face of the skirt and retain thus the folds 20; as another example, recourse can be had to zippers, of the type illustrated at 18 in FIG. 4, to ensure

  both local and controlled lifting of the skirt and retraction

  of the resulting excess material. According to another characteristic of the invention, the bottom 8 is deformable along a second transverse articulation line 22 corresponding to the front edge of the seat 8b, so that the bottom 8 has, for the seat position, a part

  extreme front 8c, inclined with respect to the seat 8b, for

  tituer a support surface of the lower legs

of the child.

  The extreme front part 8c can be located in the plane of the upper edge 10 for the seat position. For this position, the height of the skirt 9, in the extreme front zone corresponding to the part 8c, is zero, the excess material, of triangular shape, being retracted in a bellows closed by one of the zippers 18 shown at the

figure 4.

  In this figure, the nacelle has been shown in solid lines for the bed position and in phantom for the position

  seat. We see that, for the seat position, the excess of ma-

  face of the skirt in the area of the backrest 8a is substantially triangular, with an apex situated on the transverse articulation line 12; the excess material of the skirt in the areas of parts 8b and 8c are also triangular, with

  a vertex respectively on line 12 and on the trans-

  extreme front versal of the nacelle.

  We have also shown in Figure 4, using a back

  The way in which the bottom 8 can be formed. The bottom 8 comprises incorporated stiffening means constituted by slats or plates such as 23. These slats or plates are

  separate from each other; they are placed between two thick-

  sisters or layers 24, 25 of canvas or the like which are sewn

  along seam lines 26 made in the test areas

  slat placement. These lines 26 ensure the assembly of the two layers of fabric 24, 25 and define gussets or pockets for immobilizing the slats. As a variant, the seam lines 26 can be replaced by welding lines,

especially ultrasonic.

  There are at least two transverse seam lines.

  dirty 26 or the like corresponding to the articulation lines

12 and 22.

  Alternatively, the joints 12 and 22 can be

  carried out by weakening lines connecting the plates.

  In this case, the set of slats or plates is one

  holding and can also present notches of flexibility.

  By way of example, the slats or plates 23 can

  be made of polypropylene and be a few millimeters thick.

  Preferably, the stiffening means, in the parts 8a, 8b and 8c, are arranged to nevertheless have a certain flexibility, either by providing, in each part 8a, 8b and 8c, slats or plates 23 separated by lines seam 26, either by providing lines of weakness

  in the material forming the slats or plates.

  Four examples of agents have been shown in Figures 5 to 8.

  stiffening plate cements 23. These examples are taken

  in the preferred application of the invention to nacelles intended

  born to equip strollers foldable in bundles. In these examples, the stiffening means are constituted by separate plates 23 whose adjacent edges are parallel

  and separated by seam lines 26 shown in dashes.

  For clarity of the drawings, the upper layer of canvas 24

has been deleted.

  For bending in bundles, the bottoms 8 of FIGS. 5 to 8 have a central longitudinal line of articulation 27 situated in the median vertical longitudinal plane PP of the

  nacelle, this plane being a plane of symmetry.

  In FIG. 5, the back part 8a comprises, on each side of the plane PP, a longitudinal plate 23a in a trapezoid extending over the semi-width of the nacelle and followed, in the lumbar region, by two small triangular plates 23a 'and 23a "placed head to tail; the seat 8b is constituted, on each side, by a rectangular plate 23b extending, over the half-width of the nacelle, to the vicinity of the transverse articulation lines 12 and 22 materialized by seams; part 8c is similarly constructed

  at the seat 8b, by two symmetrical plates 23c.

  The plates 23a - 23c give the bottom 8 both good local rigidity and a certain overall flexibility. This flexibility can be further improved if provision is made for

  plates 23a, 23b and 23c, lines of weakness longitu-

dinals 28.

  The nacelle in Figure 6 shows the characteristic

  than being symmetrical also with respect to a trans-

  median versal QQ as regards its border 10, its skirt and its bottom 8, and preferably also as regards its retaining means 13 and its retraction means if they exist. This basket is

  intended to equip a stroller, in particular folding as shown

  as above; it is of the reversible type by simple rocker-

  ment around the nuts 7, the tilting axis of which is located in the plane of symmetry QQ, without turning the bottom 8 facing to

  face. This nacelle has two first lines of articulation-

  transverse tion 12 and two second transverse articulation lines 22, symmetrical in pairs with respect to the plane QQ. Each quadran consists of an extreme plate

  23 ac (23ca), an intermediate plate 23ab (23ba) and a plate

  that central 23ab (23ba); these plates can, like the plates

  in Figure 5, have long lines of weakness

dinales (not shown).

  For the seat position, and in the rest position

  versibility facing the road, the backrest 8a comprises the eight plates 23ac, 23ab and 23ab 'and 23ba', the seat 8b comprises the two plates 23ba and the support part 8c comprises the two plates 23ca; in the reversibility position facing the mother, the backrest comprises the eight plates 23ca, 23ba, 23ba 'and 23ab', the seat comprises the two plates 23ab and the support part

comprises the two plates 23ac.

  In the variant of FIG. 7, the backrest 8a is formed by two longitudinal trapezoidal plates 23a which define with the joint 12 an empty lumbar gusset 29, the seat 8b and the end support part 8c being constituted by plates analogous to plates 23b and 23c of Figure 5; as in this figure 5, the plates 23a, 23b and 23c can

  have longitudinal lines of weakness 28.

  While the nacelles of Figures 5 to 7 can bend in V thanks to the central longitudinal articulation 27, the nacelle of Figure 8 can bend in W. For this, it has, on either side of the longitudinal plane median PP, two additional longitudinal articulation lines 27 'located at a quarter of the width of the nacelle and produced by interruptions or weakening lines. In this figure, the plates themselves have not been shown. Good

  of course, the above characteristic of W-folding is applied

  cable to any of the pods in Figures 5 to 7.

  Figure 9 shows another characteristic of the invention. The beams 11il of the nacelle are connected by end crosspieces 30, each in the form of a compass articulated at the center at 31. The articulations 31 are of the type with stop in

  deployed position of the associated compass, corresponding to the alignment

  ment. of the two branches of the compass. The joints 31 allow-

  try folding the carrycot with the stroller or independently

  ment of it; the stopper in the open position avoids the

  closure of the basket under the action of the child's weight.

  The set can be equipped with central handles 32 allowing

  to use the carrycot in a baby carrier.

  It appears from the above that the nacelle according to the invention can, without appreciable increase in the cost price and without requiring long and delicate operations and separate accessories, be used either in the seat or in a bed with normal conformations; in particular, for the bed position, as the child has a substantially flat bottom, it can be extended on the back, on the stomach or on the side, which is not possible with the reclining seats of

prior art.
