Description

TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates to a baby bouncer. It is particularly applicable to the field of furniture for young children. STATE OF THE ART

[0002] In the field of baby bouncers, some systems feature a support frame attached to the lower or central part of the bouncer. The weight distribution when an infant is placed on such a bouncer is not optimal for ensuring good overall stability.

[0003] We also know of non-removable systems consisting of a canvas mounted on metal rods allowing the canvas to be tilted. These systems have the disadvantage of being very bulky, both in terms of weight and volume.

[0004] Some systems overcome this bulky drawback by incorporating rods that fold along an axis, aligning them with the stretched canvas when folded. However, these systems still have a minimal bulky footprint due to the frame surrounding the canvas.

[0005] Thus, there is no current system that satisfactorily addresses the bulkiness constraint of the deckchair, making it unpleasant to transport for a user.

[0006] We are familiar with patent application FR 15 51988, which discloses a folding baby bouncer with a support frame equipped with slats on either side to hold rods that in turn support other rods. However, the slats must have a certain degree of elastic deformation, or flexibility, to bend and be secured to the rods. This minimal elastic deformation renders the bouncer incompatible with safety standards. The part of the bouncer designed to support the baby's torso and head deforms, creating a risk to the baby.

[0007] Furthermore, the deckchair which is the subject of patent application FR 15 51988 presents risks of tipping over due to the small support surface on the ground.

[0008] We are aware of patent application number FR 31 17002, which discloses a folding baby lounger with a frame equipped with flexible slats. However, the flexibility of the slats does not provide sufficient support for the infant in the lounger. In particular, the load-bearing capacity is reduced when a flexible lower slat is used. This reduction in load-bearing capacity results in insufficient tension in the fabric. Consequently, an infant placed in such a lounger is not adequately supported. This type of lounger is also incompatible with certain current safety standards, since the distance between the floor and the part of the fabric closest to the floor is less than a standardized distance, specifically 15 mm.

[0009] US publication 5,095,563 is also known. This document details an infant bed suspended by means of various cords attached to two widely spaced points on a support frame, in an arrangement similar to that of a hammock. Given its particular construction, such a bed presents a risk of tipping over by pivoting around the axis passing through the two attachment points of the bed to the support frame in the event of excessive tilting or imbalance. The safety of an infant placed in such a bed is therefore insufficient, exposing the child to a clear risk of falling. DESCRIPTION OF THE INVENTION

[0010] The present invention aims to remedy all or part of these drawbacks.

[0011] Accordingly to a first aspect, the present invention relates to a deckchair according to claim 1.

[0012] Thanks to these features, the assembled baby bouncer offers adequate stability and mechanical resistance when an infant is lying on the fabric. The bouncer also complies with safety standards for infant bouncers.

[0013] Furthermore, the successive joining of the parts of the deckchair by the use of collinear interlocking joints allows the user to achieve an easy and quick assembly of the deckchair.

[0014] Furthermore, the presence of collinear interlocking parts allows the deckchair to be disassembled into several separate pieces. Specifically, certain parts of the deckchair can be detached when, for example, the deckchair needs to be stored. This makes disassembly easier. Moreover, a compact structure is achieved after disassembly. Such a structure offers significant compactness, thus facilitating storage and transport of the deckchair.

[0015] Finally, the presence of various removable parts also allows for easy replacement of one or more parts when a part is damaged or defective, without having to replace the entire frame.

[0016] In some embodiments, the lower part of the arc has two parts joined reversibly by a transverse interlocking.

[0017] Thanks to certain arrangements, the lower part has a smaller footprint when the two parts are separated.

[0018] In some embodiments, the distance between a first straight line passing through one end of the arc of the lower part and the transverse interlocking and a second straight line parallel to the first straight line and tangent to the arc is less than or equal to half the distance between a third straight line passing through both ends of the arc and a fourth straight line parallel to the third straight line and tangent to the arc.

[0019] Thanks to these features, the disassembled deckchair is more compact.

[0020] In some embodiments, a joint includes, on one part, a stop and on the other part, a retractable ratchet of a shape corresponding to the stop.

[0021] Thanks to these provisions, the joining or separating of the parts is facilitated respectively during the assembly or disassembly of the deckchair.

[0022] In some embodiments, a foot of a central part is foldable, the means of connection being a pivot joint with axis of rotation parallel to the axis of the rods.

[0023] Thanks to its design, the folding leg of the deckchair allows for a more compact structure, making it easier to store the deckchair.

[0024] In some embodiments, the deckchair also includes a means of immobilizing the foot in the unfolded position.

[0025] Thanks to these features, the immobilizing device helps to mitigate the mechanical stresses present during the use of the baby bouncer, particularly when an infant is lying on the fabric. Specifically, when the mechanical stresses are located at the junction between the base and the frame, the immobilizing device reinforces this junction, preventing the base from folding under the effect of the infant's movements. This improves the bouncer's stability and also ensures compliance with certain stability standards imposed, for example, by current regulations for baby bouncers.

[0026] In some embodiments, the means for immobilizing the foot includes: the central part comprising a first hook and a stem fixed to the proximal end of the foot and having an end forming a second hook, the two hooks being configured to snap together reversibly, the foot having at least one stop configured to come into contact with the central part in a configuration known as the "deckchair installation configuration".

[0027] Thanks to these features, the footrest locking mechanism is integrated into the structure of the deckchair, eliminating the need for a separate part. Furthermore, this locking mechanism is easily activated by the user by simply clicking the two hooks together. Specifically, a clicking sound is heard when the two hooks are clicked, providing the user with an audible indication that they are securely engaged. This clicking sound confirms that the device is ready for use.

[0028] In embodiments, the foot immobilization means includes a locking element configured to be snapped into the central part fixed to the proximal end of the foot, the locking element forming a blocking stop against a portion of the proximal end of the foot in the unfolded position.

[0029] Thanks to these features, the locking mechanism secures the leg in the unfolded position using a locking element external to the deckchair's structure. This minimizes the risk of the leg bending. Furthermore, when the locking mechanism is also integrated into the deckchair's structure, the additional locking element reinforces the leg's stability in the unfolded position. This enhances the overall stability of the deckchair's structure. In addition, the leg's manufacturing is simplified and therefore less expensive.

[0030] In some embodiments, at least one support on the ground is at least partially covered with a non-slip material.

[0031] These features limit the risk of the deckchair sliding on the floor. This improves the deckchair's safety.

[0032] In some embodiments, the deckchair has a weight of less than 2 kilograms.

[0033] Thanks to these features, the deckchair has a reduced weight and is therefore easier to transport.

[0034] In embodiments, at least one rod has a longitudinal recess of dimensions corresponding to at least one of the three parts and configured to house said at least one part when the deckchair is disassembled.

[0035] Thanks to these features, the disassembled deckchair has a reduced volume. The overall size of the disassembled parts is therefore limited. This results in a more compact disassembled structure. Such compactness makes the disassembled deckchair easier to store and transport.

[0036] According to a second aspect, the present invention relates to a kit comprising a carrying bag, two support rods for a canvas, the canvas and at least two assemblies each comprising three parts that can be assembled to form a rigid frame: a first part called "upper" comprising an attachment to a rod, a second part called "central" comprising a collinear joint to the upper part and a foot, the foot comprising: a proximal end fixed to the central part by a means of connection and a distal end, and a third part called "lower" comprising a collinear joint to the central part and an attachment to the other rod.

[0037] Thanks to these features, the bag makes it easier to transport the disassembled deckchair. Since the purposes, advantages, and specific characteristics of the kit that is the subject of this invention are similar to those of the deckchair that is the subject of this invention, they are not repeated here.

DESCRIPTION OF IMPLEMENTATION METHODS

[0039] The present description is given by way of non-limiting attribution, each feature of an embodiment being able to be advantageously combined with any other feature of any other embodiment.

[0040] Throughout the description, anything that is above is called "superior" or "high". figures 1 , 5 , 6 , 15 et 16 , which correspond to the normal configuration for using the deckchair, "lower" or "bottom" being what is at the bottom in these figures 1 , 5 ,6 , 15 et 16 The terms "vertical" and "height" are derived from these definitions. The face of the fabric configured to hold the infant is called "top" or "on," and the face of the fabric opposite the face configured to hold the infant is called "bottom" or "under." These various orientations correspond to the physical orientations of a baby bouncer, the subject of the invention, in its normal position of use, with the bouncer placed on the floor and an infant positioned in it. Note that the terms "perpendicular," "parallel," or "symmetrical" are used to describe an assembled bouncer, as shown in the illustration. figures 1 , 5 , 6 , 15 et 16 That is to say, a deckchair in its normal operating configuration, also called the "deckchair installation configuration". When the deckchair is no longer in an installation configuration, that is to say, when the deckchair is disassembled and therefore in the form of several pieces or parts, joined or not, the terms "perpendicular", "parallel", or "symmetrical" are no longer applicable.

[0041] The following definitions are recalled here: The term "rigid" refers to a material that resists torsional and shear forces and does not substantially bend under normal conditions of use. When a material "does not substantially bend," it means that the material's deformation is insubstantial and, in particular, less than a predetermined value characterized by the mechanical stresses exerted under normal conditions of use. Preferably, such a predetermined value is approximately equal to 0. Specifically, the term "rigid" is the opposite of flexible or elastically or plastically deformable. The term "collinear joint," "collinear fastener," or "longitudinal fastener" refers to a fastener that joins two parts, for example, by snapping the two parts together along an axis parallel to the length of the parts, the length of one part corresponding to the tangent of the curve defining that part at the point of the fastener.The term "collinear interlocking" does not refer to a part that retracts into another part. The term "transverse interlocking," or "transverse attachment," refers to an attachment that joins two parts, for example, by snapping the two parts together along an axis intersecting the length of the parts. The term "transverse interlocking" does not refer to a part that retracts into another part. The term "anti-slip" refers to a material that reduces the slipperiness of a surface. For example, an anti-slip material reduces the slipperiness of the floor on which the baby bouncer is installed. In other words, an anti-slip material increases the coefficient of friction between the support and the floor on which the baby bouncer is installed. The term "predetermined infant" refers to a human being with a predetermined weight, height, volume, and age.A professional in the field can, in particular, predetermine an infant based, for example, on statistical anatomical or morphological studies specific to a country or population. It should be noted that the term "infant" is a synonym for "baby" or "young child".

[0042] We observe, in figure 1 , an embodiment of the 100 baby bouncer that is the subject of the invention. The 100 baby bouncer for a predetermined infant, represented in figure 1 , comprises two support rods, 105 and 110, of a canvas 115 suspended between the rods, the rods having parallel axes.

[0043] We observe in figure 1 that the 100 deckchair has two rigid 120 frames.

[0044] Note that the 120 frame comprises three parts: a part, called "upper" 130, comprising an attachment 135 to a rod 110, a second part called "central" 131 comprising a collinear fit 111 to the upper part and a foot and a part called "lower" 140 comprising a collinear fit 111 to the central part and an attachment 145 to the other rod.

[0045] Each reinforcement, once assembled, follows a continuous curve that is differentiable at every point in a plane normal to the axes of the rods, 105 and 110.

[0046] In some embodiments, the upper part 130 is substantially curved. In other variants, the upper part 130 is straight.

[0047] In some embodiments, the upper part 130 is configured to support the fabric at the level of the infant's head. It should be noted that the fabric has, at the level of the infant's head, an angle of inclination with respect to the tangent of the lower part 140 passing through the distal end of the foot, of between 10° and 80°. This angle of inclination corresponds, for example, to the "beta angle" in the following description.

[0048] In some embodiments, the central part 131 is straight.

[0049] We note, in figure 1 , which foot 160 of the central part 131 presents: a proximal end 165 fixed to the central part 131 by a connecting means 170 and a distal end 175 forming a support on the installation floor of the deckchair 100.

[0050] In embodiments such as the one shown in figure 1 At least one rod, 105 and / or 110, has a longitudinal recess with dimensions corresponding to at least one of the three parts, 130, 131 and / or 140, and configured to house said at least one part when the deckchair is disassembled. Preferably, the lower rod 105 for holding the fabric 115 has a longitudinal recess configured to house the upper part 130 when the deckchair is disassembled.

[0051] In some embodiments, the 160 foot has a profile following a curve in the plane normal to the axes of the rods.

[0052] We observe, in figure 1 The lower part 140 forms an arc, a tangent of which passes through the distal end of the foot 160. The lower part 140 has a profile that follows an arc. It should be noted that the lower part 140 is configured to elevate the infant's feet.

[0053] Preferably, the transat 100 presents overall a plane of symmetry perpendicular to the axis of the rods, 105 and 110, and passing through the middle of said rods, 105 and 110.

[0054] In embodiments such as the one shown in figure 1 The tangent to the arc formed by the lower part 140 passes through a first support point 155 of the deckchair 100 on the ground. This first support point 155 also lies on the arc formed by the lower part. In other words, the first support point 155 corresponds to the point of tangency. We observe, in figure 1 The tangent of the arc formed by the lower part 140 passes through a second point of support of the deckchair 100 on the ground. This second point of support is located on the end of the distal part 175 of the foot 160 in contact with the ground. A frame 120 thus has at least two points of support on the installation ground.

[0055] We observe, in figure 1 , that the frame 120 has an arched shape with the extrados oriented towards the ground of installation of the deckchair 100 and the intrados oriented towards the canvas 115.

[0056] In some embodiments, each reinforcement bar 120 is a truncated semi-elliptical profile cylinder. In other words, each reinforcement bar 120 is a curved rod. In other variants, each reinforcement bar is a portion of a straight profile parallelepiped.

[0057] In embodiments such as the one shown in figure 1 The three parts, 130, 131 and 140, of a reinforcement 120 are detachable. The collinear joints of each part, 130, 131 or 140, are used for the assembly and disassembly of the reinforcement 120. In other words, the profile of a reinforcement 120 comprises at least three parts, 130, 131 and 140, equipped with collinear joints 111 configured to connect the parts, 130, 131 and 140, reversibly.

[0058] In embodiments such as the one shown in figure 1 The arc of the lower part 140 has two parts joined reversibly by a transverse interlocking 112. We observe, on the figure 1 , that the attachment 112 forms a protrusion 150. In other words, the lower part 140 has a protrusion 150 on the extrados of the bow.

[0059] In embodiments such as the one shown in figure 1 The frame 120 comprises four parts, 130, 131, 141, and 142, to be joined together. For example, the end of an upper part 130 is joined to one end of a central part 131 by means of a collinear joint 111. The second end of the central part 131 is joined to one end of a first part 141 of the lower part 140 by means of a collinear joint 111. The second end of the first part 141 of the lower part 140 is joined to one end of a second lower part 142 of the lower part 140 by means of a transverse joint 112.

[0060] Preferably, the parts 130, 131, 141 and 140 to be joined together, constituting the reinforcement 120, are of different shapes. In variants, the parts to be joined together, constituting the reinforcement 130, 131, 140, have a similar shape.

[0061] Note that the specific description of only one part of the 120 reinforcement is valid for the other parts, unless otherwise stated.

[0062] In some embodiments, a collinear interlocking joint 111 comprises, on one part, a stop and on the other part, a retractable ratchet of a shape corresponding to the stop. The collinear interlocking joint 111 forms a longitudinal attachment of the two parts, 130 and 131, 131 and 141, to be joined together.

[0063] In other words, the collinear 111 interlocking system is a two-part mechanism: one part has a notch, and the other part has an elastically deformable piece and a non-return stop that inserts into the first part until it reaches the notch and snaps into place, returning to its original shape, with the stop making contact with an edge of the notch. To release the fastening, the stop must be pressed to disengage it from the notch. This type of fastening is found on backpacks, for example.

[0064] In embodiments, the collinear interlocking 111 includes, for example, a rigid end piece fixed to one end of a part to be joined, this end piece having a cavity to receive a mechanical part projecting from one end of the other part to be joined.

[0065] In variants, at least one collinear interlocking 111 includes a magnet present on one part to be joined, this magnet being associated with a metal piece or another magnet present on the other part to be joined.

[0066] In embodiments such as the one shown in figure 1 , the transverse interlocking 112 forms a protuberance 150 on the extrados of the bow, when the parts, 141 and 142, of the lower part 140 are joined together.

[0067] Preferably, each part to be joined, 141 and 142, has a joining element, each joining element snaps into place and thus forms the protuberance 150.

[0068] It is noted that the variants described for collinear interlocking 111 are also transposable to transverse interlocking 112. A person skilled in the art can easily adapt the variants described for collinear interlocking 111 to transverse interlocking 112.

[0069] It is noted that the lower part 140 is made of a material with sufficient rigidity to allow the deckchair 100 to withstand the load well and thus comply with the standards stated above. Preferably, when the material constituting the lower part is similar to the material constituting the transverse joint 112, such a material is capable of elastic deformation. This elastic deformation allows for easier separation of the two parts, 141 and 142, of the lower part 140 when the transverse joint 112 is disengaged. Thus, a compromise is achieved between sufficient rigidity and ease of disassembly of the two parts, 141 and 142, of the lower part 140.

[0070] In embodiments such as the one shown in figure 1 The foot 160 of a central part 131 is foldable. Note that the proximal end 165 of the foot is fixed to the central part 131 of the frame 120 by a connecting means. This connecting means 170 is a pivot joint 170 with its axis of rotation parallel to the axis of the rods.

[0071] In some embodiments, each foot 160 is a rigid rod made of metal or plastic. Preferably, the distal end 175, in contact with the installation floor, is beveled.

[0072] In some embodiments, the folding foot 160 is connected by a hinge 170 to the central part 131 of the frame 120. It should be noted that the foot 160 is positioned, in its folded position, against the part 131 of the frame 120, or inside a corresponding cavity provided in the part 131 of the frame 120. In other variations, a cavity is present along the length of the longer foot 160, this cavity corresponding to the shape of the part 131 of the frame 120. In other words, in this variation, the foot 160 is positioned, in its folded position, around the part 131 of the frame 120. In such a folded position, the part 131 of the frame 120 is therefore in contact with the inside of the cavity in the foot 160. The hinge 170 provides, for example, a maximum angle of rotation for the foot 160 around of the axis of this hinge 170. The maximum angle of rotation is preferably 135 degrees.

[0073] In embodiments such as the one shown in figure 1 , the deckchair 100 also includes a means of immobilizing 101 of the foot 160 in the unfolded position.

[0074] In embodiments such as the one shown in figure 1 , the immobilization means 101 is a rigid element.

[0075] In embodiments such as the one shown in figure 1 The immobilization means 101 for the foot 160 includes a locking element 101. The locking element 101 is configured to snap into the central portion 101 fixed to the proximal end 165 of the foot. The locking element forms a blocking stop 104 against a portion of the proximal end 160 of the foot 160 in the unfolded position.

[0076] We observe, in figure 2 that the rigid element 101 comprises several parts: at least a first part 102 for the rigid element 101 to stop against a reinforcement 120, a second part 103 that can be snapped onto the reinforcement 120 and a third part 104 for the foot 160 as shown in figure 4 .

[0077] In embodiments such as the one shown in figure 3 , part 131 of the reinforcement 120 includes cross braces 126. It is noted that the cross braces 126 are cross-shaped reinforcements of the reinforcement 120. The cross braces 126 have a recess allowing, for example, for the insertion of a rigid element 101.

[0078] We observe, in figure 3 , that each first part 102 of the rigid element 101 is inserted into a recess of a cross member 126 present in the reinforcement 120.

[0079] We observe, in figure 4 , that the third part 104 of the stop against the foot 160 is in contact with a cavity present in the foot 160.

[0080] Note that the characteristics stated to describe the frame 120 of the deckchair 100 are applicable to the frame 220 of the deckchair 200 unless otherwise stated.

[0081] We observe, in figure 5 , an embodiment of the 200 transatlantic chair that is the subject of the invention. The 200 transatlantic chair is shown in figure 5 includes a means 201 for immobilizing the foot 160 in the unfolded position. In these embodiments, the means 201 for immobilizing the foot 160 includes: a central part 131 of a frame 220 comprising a first hook 202 and a rod 203 fixed to the proximal end 165 of the foot 160 and having an end forming a second hook 204.

[0082] It is noted that, in this embodiment, the immobilizing means 201 is included in the frame 220.

[0083] We observe, in figure 6 , an enlargement 50 of the frame 220 including a means of immobilizing 201 of the deckchair 200.

[0084] It should be noted that, in these embodiments, the two hooks, 202 and 204, are configured to snap into place reversibly. Furthermore, in these embodiments, the foot 160 has at least one stop 211 configured to come into contact with the central part 131 of the frame 220 in a configuration known as the "deckchair installation configuration".

[0085] We observe in figure 7 an enlarged view of the stem 203 fixed to the proximal end 165 of the foot 160 and having an end forming a second hook 204 and a stop element 211.

[0086] We observe in figure 8 a kinematic view of the two hooks, 202 and 204, included in the immobilizing means 201.

[0087] In the following description, for brackets, 202 and 204, represented in figures 8 à 14 The term "free portion" refers to a portion free of any element, and the term "solid portion" refers to a portion formed from a component of a reinforcement. Furthermore, the term "disengaged" refers to a "non-snap-fitted" configuration.

[0088] We observe, in figure 8 The first bracket 202 has a V-shaped upper portion 206 and a rounded lower portion 207. The V-shaped upper portion 206 and the rounded lower portion 207 are joined, this junction forming a rounded projecting portion 212. In other words, the upper portion 206 and the lower portion 207 of the first bracket 202 form a joint with an acute, rounded angle.

[0089] Furthermore, the lower portion 207 in rounded shape of the first hook 202 allows the rotation of the foot 160 to be guided around the axis of the hinge 170. In other words, when the two hooks, 202 and 204, are disengaged and the foot 160 is being rotated to be folded, a portion of the second hook 204 slides on the rounded lower portion 207 of the first hook 202 following a movement describing an arc of a circle.

[0090] We note, in figure 8 that the intrados of the lower, rounded portion 207 of the first hook 202 is solid. When the hooks, 202 and 204, are not engaged, as shown in figure 14 Note that the upper V-shaped portion 206 of the first bracket 202 is free at the smallest angle of the "V" and solid at the largest angle of the "V". Preferably, the smallest angle of the upper V-shaped portion 206 of the first bracket 202 has an angle between 30° and 90°, and more preferably between 45° and 90°. In other words, the upper free V-shaped portion 206 of the first bracket 202 preferably has an angle between 30° and 90°, and more preferably between 45° and 90°.

[0091] Furthermore, the projecting portion 212 is rounded and allows the two hooks, 202 and 204, to slide against each other when the two hooks, 202 and 204, are disengaged. In other words, the rounding of the projecting portion 212 allows the two hooks, 202 and 204, to be disengaged without breakage when a user wishes to fold the foot 160.

[0092] We observe, in figure 9 The second hook 204 has an upper portion corresponding to a lever and configured to receive a disengagement force from the two hooks, 202 and 204. This lever allows elastic deformation of the stem 203 at the proximal end 165 of the foot 160, as shown in figure 11 Furthermore, the second hook 204 also has a lower portion 208 in the shape of a V. The lever is opposite and in line with the axis of the V-shaped end 208.

[0093] When the brackets, 202 and 204, are disengaged, as shown in figure 14 Note that the lower V-shaped portion 208 of the second hook 204 is solid at the smallest angle of the "V" and free at the largest angle of the "V". Preferably, the smallest angle of the lower V-shaped portion of the second hook 204 is between 30° and 90°. In other words, the solid lower V-shaped portion 208 of the second hook 204 is between 45° and 90°. In other words, the second hook 204 has a shape complementary to the first hook 202. For example, the second hook 204 has a free V-shaped portion 209 opposite the projecting portion 212 and a projecting V-shaped portion 208 opposite the upper V-shaped portion 206, in the engaged position.

[0094] Note that when the two brackets, 202 and 204, are clicked into place, as shown in figure 9 The upper V-shaped portion 206 of the hook 202 comes into contact with the free V-shaped portion 209 of the second hook 204. In other words, the two V-shaped portions of the two hooks, 202 and 204, are of corresponding shape, thus allowing the two hooks, 202 and 204, to snap together. Furthermore, the part of the protruding portion 212 of the first hook 202 is present in the inverted V-shaped free portion of the second hook 204.

[0095] In the figures 9 et 10 The contact points are indicated by a dotted arrow.

[0096] We observe, in figure 9 , an installation configuration of the deckchair 200 in which the hooks, 202 and 204, are snapped into place and the foot 160 has a stop element 211 coming into contact with the part 131 of the frame 220. In other words, the contact forms a stop between the stop element 211 of the foot 160 and the frame 220. The stop element 211 is preferably a shoulder formed in the stem 203 of the proximal end 165 of the foot 160.

[0097] We observe, in figure 10 A disengagement configuration of the deckchair 200 is shown in which the lower V-shaped portion 208 of the second solid hook 204 is in contact with a part of the projecting V-shaped portion 212 of the first hook 202. This contact forms a stop between the two hooks, 202 and 204. In other words, the projecting portion 212 of the first hook 202 is abutted against the corresponding part of the second hook 204. This disengagement configuration of the deckchair 200 corresponds to a maximum angle of rotation. Indeed, it is impossible to rotate the foot any further; the maximum angle of rotation is fixed.

[0098] We also observe, in figure 10 that the angle formed by the central part 131 and each stop of the foot 160 is equal to 8°, a stop being, according to a deckchair installation configuration shown in figure 9 and the other stop being according to a configuration called "transat disengagement configuration" of transatlantic disengagement represented in figure 10 We note, in figure 10 The 8° angle is represented by a double curved arrow. Note that brackets 202 and 204 are in contact in the deckchair disengagement configuration. In alternative configurations, this angle has a value less than 8°.

[0099] Thus, when a user folds foot 160, an additional safety feature is added. Foot 160 comes to a stop against a surface of hook 202, depending on the disengagement configuration of the lounger, to prevent accidental folding. The user must manipulate the second hook 204 to actually disengage foot 160 from the surface of hook 202 and fold foot 160.

[0100] We observe, in figure 11 A dynamic view of a manual unlocking achieved by disengaging the two hooks, 202 and 204. This disengagement is achieved by pushing the lever of the second hook 204 in a direction opposite to that of hook 202. Note that the disengagement visible in figure 11 is possible when the foot is initially in a disengagement configuration of the 200 deckchair shown in figure 9 Furthermore, the projecting portion 212 is rounded to allow disengagement of the second hook 204. An elastic deformation of the stem 203 at the proximal end 165 of the foot 160 is also visible in figure 11 During this elastic deformation of the rod 203, the two V-shaped portions, 206 and 208, of the hooks, 202 and 204, slide one on the other.

[0101] We observe in figure 12 a dynamic view that temporally follows the view represented in figure 11 We observe, in figure 12 , the total disengagement of the two hooks, 202 and 204, and the start of rotation of the foot 160 around the axis of the hinge 170. This disengagement corresponds to the total disengagement of the rod 203 and of the part 131 of the frame 220.

[0102] We observe in figure 13 a dynamic view that temporally follows the view represented in figure 12 We note, in figure 13 , the total disengagement of the rod 203, and the continuity of the rotation of the foot around the axis of the hinge 170.

[0103] We observe, in figure 14 , a dynamic view that temporally follows the view represented in figure 13 We note, in figure 14 , the total disengagement of the rod 203, and the total rotation of the foot around the axis of the hinge, the foot being in a totally folded position around the part 131 of the frame 220.

[0104] It should be noted that a frame 120 is rigid. In other words, the upper, middle, and lower parts, 130, 131, and 140, of the frame 120 and the foot 160 are, for example, curved blades or rods made of a rigid material known to those skilled in the art. In some embodiments, the frames 120 are made at least partly of a rigid material composed of recycled plastic. In other variations, the frames 120 are made of carbon fiber reinforced metal. The material characteristics mentioned for the frames 120 also apply to the frames 220 of the device 200.

[0105] In some embodiments, the armatures 120 and the rods, 105 and 110, of the device 100 are at least partially formed from a material selected from the following polymers: glass fiber reinforced polyamide (acronym "PA"), glass fiber reinforced polypropylene (acronym "PP"), polycarbonate (acronym "PC") and high-density polyethylene (acronym "PE").

[0106] Thus, these polymers give the frame 120 of the deckchair 100 rigidity and reduced weight. For example, in these embodiments, the deckchair 100, assembled or disassembled, weighs less than 5 kilograms, in particular less than 2 kilograms, and in particular equal to 1.3 kilograms or 1.2 kilograms.

[0107] The material characteristics stated for the 100 deckchair are also valid and applicable to the 200 deckchair.

[0108] It should be noted that the 100 and 200 baby loungers comply, for example, with the standard "NF EN 12790 of June 2009". The parameters of this standard are defined when an infant is placed in the 100 or 200 lounger. The first parameter is a seat height, referred to as "H" height, corresponding to the distance between the installation floor and the part of the fabric closest to the ground. In other words, the H height is the minimum distance between the lower part of the soft, flexible seat and the horizontal surface. The second parameter is an angle, referred to as "beta" angle according to the nomenclature, corresponding to the angle of the seat or tilt. In other words, the β angle is the angle between the backrest and the horizontal surface. A 100 or 200 lounger complies with this standard when: height H is greater than 15 mm and angle beta is between 10° and 80°.

[0109] We observe, in figure 15 , the parameters corresponding to a height H and an angle beta, associated with the norm stated previously. We denote, in figure 15 The height H is represented by a double straight arrow, and the angle beta is represented by a double curved arrow. Specifically, angle beta corresponds to an angle formed by a line E and another line F. Line E is tangent to an arc formed by a portion of the fabric serving as a backrest for the infant, that is, the part of the fabric against which the infant's back and head rest. Note that the infant's head is approximately aligned with its back; in other words, the infant's head is generally in line with its spine. Line F passes through a first point of support 155 of the baby seat 200 on the ground, corresponding to a point of tangency. In other words, line F is tangent to the arc formed by the lower part 140 in contact with the ground. Line F also passes through a second point of support located on the end of the distal part 175 of the foot 160 in contact with the ground.

[0110] We observe, in figure 16 , an enlarged view 216 of part of the deckchair 200. In this enlarged view 216, we observe: a first line, called "A", passing through one end of the arc of the lower part 140 and the transverse interlocking 112; a second line, called "B", parallel to the first line A and tangent to the arc formed by the first part 141 of the lower part 140, or to the arc formed by the second part 142 of the lower part 140; a third line, called "C" passing through the two ends of the arc formed by the lower part 140; and a fourth line, called "D", parallel to the third line C and tangent to the arc formed by the lower part 140.

[0111] In embodiments such as the one shown in figure 16 The distance between the first line A and the second line B is less than or equal to half the distance between the third line C and a fourth line D. We denote, in figure 16 , where each distance is represented by a double arrow.

[0112] The characteristics stated earlier in the description of the figures 16 And 17 The guidelines stated for the 200cm deckchair are also valid and therefore applicable to the 100cm deckchair.

[0113] In some embodiments, the fabric 115 is a mesh fabric made of natural or synthetic material of substantially rectangular shape, two opposite faces of which are each attached to a rod, 105 and 110. This connection is formed, for example, by the addition of a hook and loop fastener, known to those skilled in the art as "scratch", on one face of the fabric 115 so as to be attached to a complementary strip positioned on the same face of the fabric 115. The connection can also be made by means of snap fasteners to form a hem around the rod, 105 and 110.

[0114] In some variations, the fabric 115 is sewn around each stem, 105 and 110. The fabric thus forms a hem into which the stem is inserted. In the embodiments shown in figures 1 And 5 , the hem completely covers the stem and two holes are made in the hem to allow the fasteners, 135 and 145, to pass through the fabric.

[0115] Preferably, the fabric 115 has a concave shape when the rods, 105 and 110, are moved apart. This shape is obtained, for example, by positioning seams on the fabric 115 that cause certain parts of the fabric 115 to stretch only when the rods, 105 and 110, are moved apart.

[0116] In some variations, the connection is made by a set of eyelets and hooks (not shown) allowing the canvas 115 to be fixed around a rod, 105 or 110.

[0117] The 105 canvas can be made of waterproof, water-repellent, fleece, or other fabrics, for example, or lyocell.

[0118] Preferably, the fabric 115 has a sewn reinforcement on at least one edge extending between two rods. The reinforcement is, for example, an aramid or nylon webbing. The webbing may be sewn onto the underside of the fabric 115. In preferred embodiments, to ensure good cohesion between the fabric and the reinforcement, the fabric forms a hem on at least part of the dimension between the rods 105 and 110, and preferably along the entire side of the fabric 115.

[0119] Each rod, 105 and 110, is, for example, a bar made of plastic, metal, or wood. The lower rod 105 has fasteners 145 at each lower part 140.

[0120] In some embodiments (not shown), the canvas 115 includes a harness. This harness allows a child positioned against the canvas 115 to be secured in place. This harness is, for example, a three- or five-point harness with straps and quick-release buckles.

[0121] In some embodiments, the fasteners, 135 and 145, are a two-part system: one part having a notch, the other part having an elastically deformable piece and a non-return stop that is inserted into the first part until the stop reaches the notch and fits into it, returning to its original shape, the stop coming into contact with an edge of the notch. To release the fastener, the stop must be pressed to disengage it from the notch. This type of fastener is found, for example, on backpacks.

[0122] In variants, the fasteners, 135 and 145, have a notch made in a rod, 105 or 110, so that the attachment is made directly between at least the lower part of the frame or the upper part of the frame and the rod, 105 or 110. This notch can be surrounded by a strap of the fabric 115.

[0123] Preferably, each rod, 105 and 110, has two attachments, 135 or 145, to the lower part of a frame or the upper part of the frame.

[0124] In some embodiments, at least one support, 155 or the proximal part 175 of the foot in contact with the ground, is at least partially covered with a non-slip material. For example, the non-slip material is made of non-slip rubber or non-slip polyvinyl chloride (PVC) known to those skilled in the art.

[0125] In some embodiments, the deckchair, 100 and 200, includes a stabilizing crossbar 106 equipped with attachment means at one end of each leg 160.

[0126] For example, the stabilizing crossbar 106 is a metal or plastic rod which has, near each end, a means of attachment to one end of each leg 160. Preferably, the means of attachment has an oblong relief that fits with a corresponding relief on a leg 160. For example, the oblong relief may protrude from the crossbar 106 and fit into a corresponding groove, at least partially, in the leg 160.

[0127] In other embodiments (not shown), the means for fixing the crossbar to a foot includes a clamp with dimensions corresponding to the dimensions of the foot 136 configured to deform and at least partially surround the foot 136.

[0128] In some embodiments (not shown), the deckchair, 100 or 200, includes a support arch for mobile elements suspended opposite the canvas 115. This arch is, for example, formed by one or more rods made of plastic or metal, this arch being configured to cover at least partially the canvas 115.

[0129] For example, this bow is attached to the canvas 115 or to the frames 120, 120 or 220.

[0130] This arch includes at least one suspended movable element, this element being, for example, a toy or a stuffed animal, positioned within reach of a child positioned against the canvas.

[0131] In some variations, this arc has a rectangular or polygonal shape.

[0132] In some embodiments, when the deckchair is folded, the overall volume of the resulting folded compact structure is less than or equal to 1.5 liters.

[0133] In some embodiments, the assembled or disassembled deckchair has a weight of less than 5 kilograms, preferably less than 2 kilograms and even more preferably equal to 1.3 kilograms.

[0134] In embodiments (not shown), the deckchair, 100 or 200, includes a removable protective canopy, attachable to the canvas 115 or to the frames 120, 120 or 220, covering at least part of the canvas 115. Preferably, when the canopy is attached to the frames, 120 or 220, the canopy is attached to the upper parts 130 of the frames, 120 or 220.

[0135] This canopy is, for example, a flexible structure roughly in the shape of a half-cylinder of revolution, attached to the fabric 115 or to the frames 120 or 220. This canopy includes, for example, a fabric that is at least partially opaque and filters ultraviolet rays. In other words, the canopy is made of a material that is at least partially reflective of ultraviolet (UV) radiation. Thus, the canopy placed over the infant will protect the infant's skin from the UV rays emitted by the sun.

[0136] In some embodiments (not shown), the deckchair, 100 or 200, includes a mesh fabric attached to the canopy and the fabric 115, covering a different portion of the fabric 115 than the portion covered by the canopy 160. For example, this mesh fabric is attached to the canopy and the fabric 115 by a hook-and-loop or snap fastening system. The mesh of this fabric preferably has an open spacing that prevents insects such as mosquitoes from passing through it. Thus, the mesh fabric prevents mosquitoes from reaching the infant on the deckchair. In some variations, this mesh fabric is impregnated with insecticide.

[0137] In embodiments (not shown), the deckchair, 100 or 200, includes a means for capturing the temperature near or on the deckchair, 100 or 200, and a means for signaling information representative of the temperature captured.

[0138] The means of capturing the temperature is, for example, an electronic thermometer positioned on one of the constituent elements of the deckchair, 100 or 200.

[0139] For example, the signaling means is a disc that changes color according to the temperature captured by the effect of the temperature or by the effect of a command issued by the capture means.

[0140] In some variations, this signaling method is a display screen showing information representative of the temperature captured.

[0141] In some variations, this signaling method is a light-emitting diode emitting a light signal depending on the temperature detected.

[0142] In some variations, this signaling method is an antenna configured to transmit a wireless signal towards a remote terminal. This wireless signal carries information representing the detected temperature or whether the detected temperature has exceeded a predetermined threshold. This antenna is, for example, configured to transmit according to the Bluetooth standard, IEEE 802.11 (also known as "Wi-Fi"), or using radio frequencies.

[0143] In embodiments (not shown), the deckchair, 100 or 200, includes an image sensor fixed to an armature, 120 or 220, and a means of transmitting the captured images.

[0144] For example, the image sensor is an optical sensor attached to a mechanical part fixed to a frame, either 120 or 220. When this image sensor is powered, image capture is continuous. In some variations, image capture depends on the detection of a vibration or a sound signal nearby. This image sensor is, in some variations, removable.

[0145] The means of transmitting the captured images is, for example, an antenna configured to emit a wireless signal towards a remote terminal. This wireless signal contains information representing at least one captured image. This antenna is, for example, configured to transmit according to the Bluetooth standard, IEEE 802.11 (also known as Wi-Fi), or radio frequencies. In some variations, this antenna is combined with the antenna used to implement the signaling system.

[0146] In embodiments (not shown), the transatlantic carriage, 100 or 200, includes a means for orienting the image sensor controlled according to the reception of an orientation command.

[0147] For example, the image sensor orientation means is a mechanical support for the freely rotating image sensor, the rotation of which is achieved by a motor. The movement of this motor is controlled by receiving an image sensor orientation command from a receiving means. This receiving means is, for example, an antenna configured to receive a wireless signal containing information representative of an orientation command. This antenna is, for example, configured to transmit according to the Bluetooth standard, IEEE 802.11 (also known as Wi-Fi), or radio frequencies. In some variations, this antenna is combined with the antenna used to implement the signaling means or the transmission means.

[0148] In some variations, the image sensor is movable along two orthogonal axes of rotation.

[0149] The orientation command is issued, for example, by a user's communicating portable terminal, such as a smartphone or a digital tablet, for example.

[0150] In some variations, the received command includes a command: of continuous image stream transmission, periodic image transmission, modification of the image transmission frequency and / or modification of an image sensor activation parameter.

[0151] In variants, an implemented antenna is configured to transmit a wireless signal carrying information representative of a charge level of a self-contained power supply powering one of the devices of the deckchair, 100 or 200.

[0152] We observe, in figure 17 , an embodiment of the 300 kit, object of the invention.

[0153] The 300 kit includes a carrying bag, two rods, 105 and 110, for holding a canvas 115, the canvas 115, and at least two assemblies each comprising three parts, 130, 131 and 140, which can be assembled to form a rigid frame, 120 or 220: a first part called "upper" 130 comprising an attachment 135 to a rod 110, a second part called "central" 131 comprising a collinear socket 111 to the upper part and a foot 160, the foot 160 comprising: a proximal end 165 fixed to the central part by a connecting means 170 and a distal end 175, and a third part called "lower" 140 comprising a collinear socket 111 to the central part and an attachment 145 to the other rod 105.

[0154] In other words, the 300 kit, represented in figure 17 includes: a deckchair, 100 or 200, disassembled and a 301 transport bag adapted to the dimensions of the deckchair, 100 or 200, disassembled.

[0155] Preferably, when the deckchair, 100 or 200, is disassembled, the parts of the deckchair, 100 or 200, are rolled up by the canvas 115 of the deckchair, 100 or 200. In other words, the canvas 115 of the deckchair, 100 or 200, forms a rolled envelope, the parts of the deckchair, 100 or 200, being arranged inside this envelope.

[0156] In embodiments such as the one shown in figure 17 The carrying bag 301 has an opening defined by a drawstring 302 and a stopper 303. The opening of the carrying bag 301 is configured to insert the disassembled baby lounger, 100 or 200, and close the bag 301. In other words, after inserting the disassembled baby lounger, 100 or 200, into the carrying bag 301, the opening of the bag 301 is closed with the drawstring 302. Such a closure and tightening mechanism is notably used in duffel bags. Note that the tightness of the drawstring 302 is maintained by the stopper 303. In other words, the stopper 303 is configured to lock the opening of the bag 301 in a closed position. We observe, in figure 17 , that the 301 carrying bag is a cylindrical trunk when the deckchair, 100 or 200, is placed inside.

[0157] In variants, such as the one shown in figure 18 The carrying bag 306 of a kit 305 is a roll-up bag. It can be seen that the roll-up bag 306 has two straps 307 to hold it in place. In this version, each strap 307 has a hem 308 at one end and a hook 309 at the other. When the bag 306 is rolled up, the hooking of the hem 308 of a strap 307 onto the hook 309 of the same strap 307 secures the bag 306 in place. In this version, this hooking is achieved by passing the hook 309 through a groove formed by the hem 308. In other versions, the two ends of a strap 307 are joined by snapping two parts together; this type of fastening is found, for example, on backpacks. In other versions, the two ends of a 307 strap are attached by a self-gripping fabric (“scratch” in English).For example, one end of the strap has a hook and loop fabric and the other end of the strap has another matching fabric configured to adhere reversibly to the hook and loop fabric.

[0158] We observe, in figure 19 , the partial winding of the rolled bag 306, corresponding to an intermediate configuration between winding and unwinding the bag 306.

[0159] We observe, in figure 20 The bag 306 is fully unrolled. Note that the bag 306 has an internal cavity in which the deckchair, 100 or 200, is placed. Note that the parts of the deckchair, 100 or 200, are rolled up by the fabric 115 of the deckchair, 100 or 200.

[0160] In other variants, such as the one shown in figure 21 The carrying bag 311 of a kit 310 is a so-called "zippered" bag 312. Preferably, the bag 311 forms a truncated cylinder. For example, the bag 311 forming a truncated cylinder has a height of approximately 40 cm and a diameter between 10 cm and 15 cm.

[0161] We observe, in figures 21 et 22 The zipper 312 of the bag 311 is located on the lateral surface of the truncated cylinder. The zipper 312 extends over two opposite portions, meaning that each portion is close to each circular surface at one end of the truncated cylinder. These two opposite portions form a circle, each circle delimiting a surface substantially parallel to the circular surfaces at the two ends of the truncated cylinder. Note that the circular surfaces are delimited by a directrix of the truncated cylinder. Preferably, the zipper does not extend over the entire circumference of the circles. In other words, the two portions containing the zipper 312 each have a free portion without the zipper 312.

[0162] We observe, in figure 21 that the zipper 312 also extends along a portion present on the lateral surface of the truncated cylinder, this portion being parallel to the height of the cylinder. In other words, such a portion includes a generatrix of the truncated cylinder.

[0163] In embodiments such as that represented in figure 21 The bag has two carrying handles.

[0164] In some embodiments, assembly and / or operating instructions for the baby lounger, 100 or 200, are printed in pictogram form on a surface of a bag, 301, 306, or 311. Preferably, in some embodiments of the bag, 306 or 311, the instructions are printed on an internal surface of the bag, 306 or 311. Preferably, a carrying bag, 301, 306, or 311, includes at least: a handle 313 allowing the bag, 301, 306 or 311 to be lifted and carried, a strap allowing the bag, 301, 306 or 311 to be carried over the shoulder, and / or a shoulder strap allowing the bag, 301, 306 or 311 to be carried in a manner similar to a backpack.
