Description

DESCRIPTION

Folding cot

Technical field

This description refers to a folding cot.

A bed of this type can be used, in particular, as a crib or a bed for a baby or a child, for sleeping and can also be used as a pen or corral.

Background

There are already many types of folding beds for children. One of the best known examples is that of the "umbrella-type folding yard" that is the subject of US patent application 4,811,437 and numerous variants thereof are known.

A crib of this type is very suitable for a small child to sleep or play inside, since it offers a good-sized space that is comfortable, safe and robust. In addition, the floor of this crib is raised, which not only makes it possible to isolate the child from the ground, but also prevents the parents from bending too much in order to place the child at the bottom of the crib or take out To the child inside. Another cradle of this type is known from GB164886 A.

However, existing "folding umbrella" cribs are not entirely satisfactory. Specifically, its folding and unfolding are difficult operations that comprise a plurality of steps that, if not carried out very precisely, can prevent the blocking or unlocking of the cradle. In addition, the umbrella-type folding cribs all comprise a separate mattress that has to be removed before the cradle frame is folded and then has to be wrapped around the folded frame. The folding / unfolding of the mattress therefore requires additional handling steps. On the other hand, the mattress is not protected during transport unless a transport bag is used in which the cradle frame and mattress are stored, so it requires the provision of such a bag and stages of additional handling

Therefore, there is a need for a new type of folding crib.

General description

The invention relates to a folding cradle that can adopt a deployed position and a folded position, comprising a cradle base that is horizontally oriented in the deployed position, a first frame that is vertically oriented in the deployed position, and a second frame which is vertically oriented in the deployed position. This cradle comprises a first Sarrus mechanism or similar mechanism formed by the first frame, the second frame and at least two articulated arms, namely, a lower arm and a side arm. Each arm connects the first and second frames to each other, and the arms guide the movement of these frames towards / away from each other during the folding / unfolding of the cradle. The cradle base is formed, at least in part, by the lower arm of the first mechanism.

A folding crib of this type can be used, in particular, for a child, especially a baby or toddler, to put it to bed. In particular, it can be used as a cot or bed and / or as a corral or corralito. This cradle has the advantage of being very easy to fold or unfold thanks to the mechanism used. This mechanism makes it easier to fold / unfold the cradle by guiding the movement of the cradle frames towards / away from each other, without the need for additional guiding elements and, therefore, without complicating the cradle structure. In particular, such a mechanism does not require a guide or slide rail to guide the movement of the frames towards / away from each other.

A Sarrus mechanism is generally defined as a spatial mechanism comprising two plates (in this case the frames) that are interconnected by at least two articulated arms and can move towards / away from each other by means of a rectilinear movement. Each of the articulated arms comprises segments that are connected to each other and to the plates by means of pivot connections. The axes of these pivot connections are parallel to each other and perpendicular to the direction of the rectilinear movement mentioned. On the other hand, the groups of axes of at least two of the arms have respective directions that are not parallel. In general, the directions of the axis groups are perpendicular to each other. Said mechanism has the advantage of having a single degree of mobility: the two plates can move with respect to each other only by the aforementioned rectilinear movement, that is, by a translational movement.

In some embodiments, the first mechanism is a Sarrus mechanism. However, the invention is not limited to Sarrus mechanisms in a strict sense, and encompasses similar mechanisms to convert the limited circular movement of a segment of one of the articulated arms of the mechanism into a substantially movement. rectilinear plates (in this case the frames) towards or away from each other.

In some embodiments, the cradle comprises a third vertical frame, and a second Sarrus mechanism or similar mechanism comprising the second frame, the third frame and at least two articulated arms, namely, a lower arm and a side arm. Each arm connects the second and third frames to each other, and the arms guide the movement of the frames towards / away from each other during the folding / unfolding of the cradle. The cradle base is then formed in part by a lower arm of the second mechanism.

The second mechanism is therefore coupled to the first mechanism, the two mechanisms having the second frame in common, and the cradle base is formed by the lower arms (i.e., the arms that are horizontal in the deployed position) of the Two mechanisms The presence of the second frame between the first and third frames makes it possible to easily create a storage space for storing, in particular, the bedding, such as a mattress, a sheet, a blanket and / or a comforter.

In some embodiments, the first mechanism is a Sarrus mechanism that allows the translational movement of the first frame with respect to the second frame along a longitudinal axis of the cradle, and the second mechanism is a Sarrus mechanism that allows movement of translation of the third frame with respect to the second frame along said longitudinal axis. In other words, the first and second mechanisms are "aligned" and develop in the longitudinal direction of the cradle.

In some embodiments, the first and second mechanisms are Sarrus mechanisms. These mechanisms can be symmetric with respect to the second framework.

In some embodiments, in the folded position, the upper or vertex of the lower arm is located below the one or more vertical arms of the mechanism. This makes it possible to avoid interactions between the arms during the folding of the cradle and, therefore, to make the latter easier. This also makes it possible to obtain a compact fold.

In some embodiments, the cradle comprises side barriers that extend between the frames and are oriented vertically in the deployed position, and in which the first and / or second mechanisms comprise two side arms that form, at least in part, the side barriers of the cradle. Such side barriers are useful to prevent a child from leaving the crib on their own.

In some embodiments, the first and second arms are arranged symmetrically with respect to the median longitudinal plane of the cradle.

In some embodiments, the cradle has symmetry with respect to a longitudinal median plane, this plane is vertically oriented in the deployed position.

In some embodiments, in the folded position, the vertices of the lateral arms are facing each other and at a distance from each other. This distance makes it possible to avoid interactions between the lateral arms during the folding of the cradle and, therefore, to make the latter easier. This also makes it possible to obtain a compact fold. Alternatively, the side arms can be placed at different heights so that, in the folded position, the arms are positioned one above the other.

In some embodiments, the crib comprises a mattress and the mattress is housed within one of the frames in the folded position. In particular, the thickness of the frame may be greater than the thickness of the mattress. This makes it possible to protect the crib mattress while it is being transported.

In some embodiments, the second frame comprises a lower cross member, and the cradle base is formed in part by this lower cross member.

In some embodiments, the mattress is pivotally mounted on one of the frames. In particular, the mattress can be pivotally mounted at the bottom of the frame. For example, the mattress can be pivotally mounted in the second frame, in the lower transverse member. This allows you not to have to remove the mattress from the crib before the latter folds.

In some embodiments, a loop extends between the mattress and the lower arm, so that, from the deployed position, the pivoting of the mattress with respect to the second frame causes the lower arm to fold. This makes it even easier to fold the crib.

In some embodiments, each of the frames has two lateral uprights and, in the deployed position, these uprights are vertically oriented and a part of the uprights extends below the cradle base in order to form the cradle legs. This makes it possible to raise the cradle base with respect to the ground and, therefore, separate the child from the ground, and prevent the parents from bending too much in order to place the child at the bottom of the cradle, or Sacred the child from within.

In some embodiments, at least the lower arm is formed by at least two segments that are articulated with each other and adjacent frames by means of hinges, allowing a first hinge for one of the segments to rotate with respect to one of the frames on a first axis of rotation, allowing at least a second hinge for the segments to rotate with respect to another around at least a second axis of rotation, and allowing a third hinge for another segment to rotate with respect to the other frame around a third axis of rotation. The first, second and third axes of rotation are parallel to each other. In particular, the lower arm can be formed from two segments that are articulated with each other.

In some embodiments, all the arms of the one or more mechanisms have the same configuration, with two articulated segments, such as the lower arm.

In some embodiments, the segments are panels. These panels can be solid or provided with a cutout.

In some embodiments, at least one of the arms of the one or more mechanisms is equipped with a stop system that prevents the arm from folding out of the cradle in the deployed position. Therefore, the lower arm may be equipped with a stop system that prevents the arm from folding out of the cradle in the deployed position. In other words, since the lower arm is in a horizontal plane in the deployed position, the stop system prevents this arm from folding down beyond the horizontal plane. Similarly, the one or more side arms may be equipped with a stop system that prevents the arm from folding out of the cradle in the deployed position. In other words, since the side arm is in a vertical plane in the deployed position, the stop system prevents this arm from folding outwards beyond the vertical plane.

The stop system can be placed on the hinges and, in particular, on the hinge that is located between the arm segments. It can be, for example, a projection that is fixed to the end of one of the segments, without passing through the hinge, and against which another segment abuts in the deployed position. It can also be a stop system integrated in the hinge. Generally, any system that can prevent the hinge from turning in one direction from a predefined hinge position may be suitable.

The aforementioned features and advantages, together with other features and advantages, will become apparent upon reading the following detailed description of the exemplary embodiments of the proposed folding crib. This detailed description refers to the attached drawings.

Detailed description of the examples

Exemplary embodiments are described in detail in the following text with reference to the attached drawings. These examples illustrate the features and advantages of the invention. However, it should be noted that the invention is not limited to these examples.

Figure 1A shows the frame of an example of a folding crib, in the deployed position. The folding crib is a small folding bed and can be used for children to sleep or play. In other words, it can be used as a crib or play yard.

The cradle frame comprises a rigid, U-shaped central frame 1. The central frame 1 is an example of a "second frame" in the sense of the invention. The central frame 1 comprises two uprights 2, 2 ', which are connected in its lower part by a lower transverse member 3. The uprights 2, 2' are referred to as 'central uprights' in the following text. The central uprights 2, 2 'can extend below the lower transverse member 3 in order to form the central legs 4, 4'. The central uprights 2, 2 'are oriented vertically, while the transverse member 3 is oriented horizontally.

In the present application, and unless otherwise specified, the horizontal and vertical directions are considered with reference to the deployed position of the cradle, under normal conditions of use. The upper part and the lower part are defined in the vertical direction.

The cradle frame comprises two Sarrus mechanisms S1 and S2 that have the central frame 1 in common. These two mechanisms are symmetrical with respect to the central frame 1, that is, with respect to the middle plane of this frame 1.

The first Sarrus S1 mechanism includes, in addition to the central frame 1:

- an end frame 5 comprising two uprights 6, 6 '(referred to as' corner uprights' in the following text) that are connected by an upper transverse member 8. They can also be connected by a lower transverse member 9 to increase the stiffness of the frame 5. The corner studs 6, 6 'can be extended below the lower transverse member 9 to form the legs 7, 7'. The end frame 5 is parallel to the central frame 1;

- two horizontal fins or panels 10, 11 which are mounted in order to pivot with respect to each other around a horizontal axis BB 'and are mounted in order to pivot in the end frame 5 around a horizontal axis AA' and in the central frame 1 around a horizontal axis CC ', respectively;

- two vertical fins or panels 12, 13 that are mounted in order to pivot with respect to each other around a vertical axis EE 'and are mounted in order to pivot at the vertical end 6 around a vertical axis DD' and in the central stile 2 around a vertical axis FF ', respectively; Y

- two other vertical fins or panels 12 ', 13' which are mounted in order to pivot with respect to each other around a vertical axis HH 'and are mounted in order to pivot at the vertical end 6' around a vertical axis GG 'and in the central post 2' on a vertical axis II ', respectively.

The end frame 5 is an example of a "first frame" in the sense of the invention. The end frame 5 may be rigid and its dimensions may be similar to those of the central frame 1. In particular, the height of the corner studs 6, 6 'corresponds to the height of the central studs 2, 2', and the leg height 7, 7 'corresponds to that of the central legs 4, 4'.

The horizontal panels 10, 11 and the three hinges of the axes AA ', BB' and CC 'form an articulated arm. This articulated arm is an example of a "lower arm" in the sense of the invention, the two panels 10, 11 forming the "segments" of this arm.

In the example, the two horizontal panels 10, 11 are rigid and of the same size. They are placed so as to form, in the deployed position, a horizontal flat surface that is continuous with the upper surface of the central transverse member 3, in which it is possible to arrange the bedding (for example, a mattress, a sheet, a blanket and / or a comforter). In other words, the two horizontal panels 10, 11 and the central cross member 3 form a part of the cradle base. The horizontal panels 10, 11 may be solid or, conversely, be hollow in order to limit the weight of the cradle. In the example, the horizontal panels 10, 11 have an opening that passes through their center and are in the form of a rectangular frame.

The hinge of the BB axis' connecting the horizontal panels 10, 11 is designed to allow the panels to fold up when the axes AA 'and CC' move towards each other. On the contrary, the hinge of the BB axis' is equipped with a stop system (not shown) for locking the horizontal panels 10, 11 in such a way that it cannot descend beyond the horizontal position (i.e. the panels cannot be folded down beyond the horizontal plane in which they are in the deployed position).

Advantageously, in order to make it easier to fold the horizontal panels 10, 11, the axes AA ', BB' and CC 'are equidistant. This also makes it possible to obtain a compact structure in the folded position, the panels then substantially overlap.

The side panels 12, 13 and the three hinges of the axes DD ', EE' and FF 'form an articulated arm. This articulated arm is an example of a "side arm" in the sense of the invention, the two panels 12, 13 forming the "segments" of this arm.

The side panels 12 ', 13' and the three hinges of the GG ', HH' and II 'axes also form an articulated arm. This articulated arm is an example of a "side arm" in the sense of the invention, the two panels 12, 13 forming the "segments" of this arm.

In the example, the vertical panels 12, 13, 12 ', 13' are rigid and of the same size. The hinges of the axes EE 'and HH' connecting the vertical panels 12, 13 and 12 ', 13', respectively, are designed to allow them to fold inwards when the axes DD 'and FF' move one towards the another and the axes GG 'and II' move towards each other, respectively. In addition, said hinges are equipped with a stopper device (not shown) to prevent vertical panels 12, 13, 12 ', 13' from folding outward beyond the vertical plane in the that are in the deployed position. In order to make it easier to fold the vertical panels 12, 13, 12 ', 13', the axes DD 'EE' and FF 'are equidistant, as are the axes GG', HH 'and II'.

The second mechanism of Sarrus S2 is identical to the mechanism S1, and these mechanisms S1, S2 are symmetrical with respect to the middle axis of the central frame 1. Therefore, for the sake of brevity, the mechanism S2 will not be described in more detail. The elements of the mechanism S2 that are similar to the elements of the mechanism S1 are provided with the same reference numbers increased by 100.

In order to fold the cradle (Figure 1A), the end frames 5, 105 move towards the center frame 1. This has the effect of making the horizontal panels 10, 11, 110, 111 fold up and make the vertical panels 12, 13, 112, 113 and 12 ', 13', 112 ', 113' fold inwards. The panels fold simultaneously and the end frames 5, 105 and the central frame 1 remain parallel to each other during folding. In particular, in the example, the corner uprights 6, 6 'remain parallel to the central uprights 2, 2', while the upper transverse member 8 and the lower transverse member 9 of the end frame 5 remain parallel to the transverse member central 3 of the central frame 1. The same applies to the end frame 105 and the central frame 1.

Therefore, all that is necessary is to exert horizontal forces at any point of each end frame 5, 105 so that the entire structure of the cradle is folded over itself. These forces are indicated by the arrows Z in Figure 1B.

When the cradle is fully folded (Figure 1C), the end frames 5 and 105 are pressed against each side of the center frame 1. Therefore, a particularly compact flat fold is obtained.

The folding crib can be equipped with a locking device (not shown) to keep it in the folded position. This may be, for example, hooks to keep the end frames 5, 105 near or in contact with the central frame 1, or a belt surrounding these three frames of 1, 5, 105.

The folding crib can be equipped with a handle (not shown) for easy transport in the folded position.

In order to deploy the cradle, all that is necessary is for the user to move one of the end frames 5 and 105 away from the other so that the entire cradle structure is fully deployed, that is, until the horizontal panels 10, 11 (110, 111) are in one and the same horizontal plane, vertical panels 12, 13 (112, 113) are in one and the same vertical plane, and panels 12 ', 13' (112 ' and, 113 ') are in one and the same vertical plane.

In the example, the height of the vertical panels 12, 13, 12 ', 13' (112, 113, 112 ', 113') is less than the height of the central uprights 2, 2 ', reduced by the length of each one of the horizontal panels 10, 11 (110, 111). Therefore, vertical panels do not interfere with horizontal panels during folding or unfolding. In other words, in the folded position, the vertex of the lower arm formed by the hinge of the axis BB 'located between the panels 10 and 11 is located below the lateral arms of the mechanism S1 (S2). The vertical panels 12, 13, 12 ', 13' (112, 113, 112 ', 113') therefore do not overlap the horizontal panels 10, 11 (110, 111) in the folded position. In addition, the vertical panels 12, 13 (112, 113) do not overlap the vertical panels 12 ', 13' (112 ', 113') in the folded position.

The cradle may also comprise a mattress 14 that rests, in the deployed position, on the horizontal surface defined by the central transverse member 3 and the horizontal panels 10, 11, 110, 111 of the mechanisms S1, S2.

It can be seen that in the folded position, because of the width of the uprights 2, 2 '(see Figure 1C), the cradle frame forms a space that is free of any mechanical element within the central frame 1, and delimited by the central uprights 2, 2 'and the central transverse member 3. This space can be used to store bedding and, in particular, a mattress.

This configuration offers the following advantages:

- the bedding remains protected inside the frame while the crib is being transported,

- The frame of the crib and the bedding can be transported together, without there being a need to keep them together in a bag.

Figures 2A to 2D show longitudinal sectional views of the folding sequence of an example of a folding cradle. This cradle comprises the frame of Figures 1A to 1C and a folding mattress 14. In this example, this mattress 14 is capable of folding in order to make it easier to store in the aforementioned free space. The mattress 14 may be more or less rigid; being able to incorporate a base plate 16 to increase its rigidity

In the example, mattress 14 comprises:

- a pad 15; Y

- an articulated base plate 16, with the same dimensions as the pad 15, composed of three elements: two boards 17 and 117, and a central strip 18 with a width substantially equal to that of the central cross member 3. These three elements are articulate around a pair of transversal axes.

The pad 15 can be made of an elastic material, for example, a foam, and has a rectangular shape, delimiting the bottom of the cradle in the deployed position.

The pad 15 and the articulated base plate 16 can be held together, for example by means of a cover that encloses them both.

The central strip 18 may be provided with a fixing device (not shown) for fixing to the central frame 1 in order to limit the movements of the folding mattress 14 with respect to the cradle frame, both in the deployed position and in the folded This fixing device may comprise, for example, hook and loop strips of the "Velcro" type, pressure fasteners, zippers, etc.

The mattress 14 can be symmetrical with respect to the middle plane of the central frame 1.

The mattress 14 can be folded before the cradle structure is folded, as shown in Figures 2B and 2C. All that is necessary for this purpose is to raise each of the ends of the boards 17 and 117 (Figure 2B).

This configuration offers the following advantages:

- it is not necessary to remove the mattress 14 before folding the cradle; Y

- mattress 14 does not increase the volume of the folded crib.

In the example, the lower part of the mattress 14 is equipped, on each side, with at least one loop, or tensioner 19 (119), which connects each of the boards 17 (117) to a point of the structure that is located near the hinge between panels 10 and 11 (110 and 111). This point may be located either on panel 10 (110), as illustrated in Figures 2A to 2C, or on panel 11 (111), or on the hinge.

The tensioners 19, 119 can be flexible elements, of the cable, chain, rope or belt type.

The length of the tensioners 19, 119 is calculated in such a way that they are tensioned when the plates 17 and 117 reach the almost vertical position, as illustrated in Figure 2C. The folding of the plates 17 and 117 thus begins the folding up of the panels 10 and 11, and therefore also the folding of the vertical panels 12, 13, 12 ', 13' inwards. Therefore, it is very easy to fold the entire frame by bringing one of the end frames 5, 105 towards the other, as described above and illustrated in Figures 1B and 1C.

In the folded position (see Figure 2D), the mattress 14 folds in two inside the central frame 1. In addition, the tensioners 19, 119 release again.

On the contrary, during the deployment of the cradle, when the panels 10 and 11 are almost open outwards in a horizontal position, the tensioning of the tensioners 19, 119 causes the mattress 14 to open and the boards 17 and 117 to bend, making it easy to place mattress 14 in a flat position at the bottom of the crib. The deployment of the cradle can be represented taking into account, in this order, Figures 1C, 1B and 1A or Figures 2D, 2C, 2B to 2A, with the arrows representing a movement or force oriented in the opposite direction.

For the child's safety, each of the mechanisms S1, S2 may be equipped with one or more locking devices (not shown in the figures) to prevent accidental folding of the cradle. These locking devices can act on the vertical panels 12, 13, 12 ', 13', 112, 113, 112 ', 113' in order to keep them in the deployed position. These locking devices are less useful in the horizontal panels 10, 11, 110, 111, which are naturally kept in the horizontal position by the combined weight of the mattress 14 and the child.

One or more locking devices may, for example, be provided in one of the following groups of hinges, or any combination of these areas:

- the corner hinges between the vertical panels 12, 12 '(112, 112') and the end frame 5 (105) on the axes DD 'and GG';

- the corner hinges between the vertical panels 12 and 13 (112, 113), and 12 'and 13' (112 ', 113') on the axes EE 'and HH';

- the hinges between the vertical panels 13, 13 '(113, 113') and the central frame 1 on the axes FF 'and II'.

For the child's safety, all openings in the crib can be closed. For this purpose, Figure 3 shows an example of a cradle frame, in the deployed position, equipped with a cover or lining that mainly comprises:

- textile end panels 25 and 125 that close the end frames 5 and 105, respectively;

- textile side panels 26, 126, 27 and 127 that close the spaces between vertical panels 12, 13, 112, 113, 12 ', 13', 112 ', 113' and horizontal panels 10, 11, 110, 111, 10 ', 11', 110 ', 111'.

All textile panels 25, 125, 26, 126, 27 and 127 can be joined to form a single inner lining of the folding cradle.

The textile side panels 26, 126, 27 and 127 are sufficiently flexible to allow the cradle frame to be folded as described above and as shown in Figures 1A to 1C.

All or some of the textile end panels 25 and 125 or the textile side panels 26, 126, 27 and 127 could be made of translucent fabric or mesh, so as to allow the child to see outside the crib, and conversely allow Parents watch over their children.

Figures 4A and 4B show another example of a folding cradle, which differs from that of Figure 3 in that textile end panels 25 and 125 have been replaced by rigid panels 28 and 128, respectively. Therefore, in the folded position (Figure 4B), the folding crib has the appearance of a flat rigid sheath, effectively protecting the rigid panels 28 and 128 of the mattress 14 and the moving parts of the cradle.
