    Child's bed
    The invention relates to a child's bed.
    It is known to provide a child's bed with side gates that are movably connected to a child's bed supporting structure of a bed base. This provides the possibility of allowing a child to stay safely in the child's bed, on the one hand, and on the other hand making it possible to gain relatively easy access to the child by moving the side rail downwards. This displacement may concern a linear (vertical) displacement, but from the point of view of working conditions it is often advantageous to allow the side rail to swing at least partially below the bed base, so that sufficient space remains underneath the bed base for (the knees of) a caregiver person, which benefits the accessibility of the bed base and the child, and thus the working attitude of the caregiver. However, the design of the child's cot comprising the movable side rails is subject to international safety standards, in particular in order to be able to counteract as much as possible the child's limbs between the side rail on the one hand and the bed base on the other hand. The distance between the movable side rail and the bed base must, for example, be a maximum of 2.5 centimeters according to the DIN standard, regardless of the orientation of the side rail relative to the bed base. In addition, the height of the movable gate must be at least 65 centimeters. In the new DIN standard 32623, stricter requirements are set for the construction of the child's bed, whereby the height of the movable side rail must be at least 80 centimeters. The distance restriction that relates to the maximum distance between the side rail and the bed base is thereby maintained. The consequence of this new standard is that the aforementioned movement, in which the side rail is at least partially moved below the bed bottom in order to improve the accessibility of the bed bottom, can no longer be applied, since pivoting of the higher side rail will lead to the the distance restriction prescribed in the standard can lead to physical contact between the side rail and the bed base or the supporting structure, which can block further movement of the side rail. In order to be able to solve the above-mentioned structural problem, a choice could be made to divide the side rail into a mobile lower gate part, for example with a height of 65 centimeters, and a stationary upper gate part, for example with a height of 15 centimeters, whereby the conventional swivel mechanism would can be maintained. However, the use of such a segmented gate is not preferable because the stationary gate part, often positioned at eye level, will considerably impede the accessibility of the bed base for a caregiver.
    It is an object of the invention to provide a child's bed whose wall can be moved in an improved manner.
    To this end, the invention provides a child's bed, comprising: a support structure, a bed base connected to the support structure, a plurality of walls connected to the support structure, the bed base surrounding it, at least one wall being movable relative to the bed base between an upper position, in which a substantial part of the relevant wall is positioned higher than the bed base, and a lower position, in which a substantial part of the relevant wall is positioned lower than the bed base, and in which at least a part of the relevant wall is positioned under the bed base, and at least at least one guide element connected to the support structure for conductively pivoting the movable wall between the upper position and the lower position, wherein the guide element is adapted to pivot the movable wall according to a substantially exponential path curve. By moving the displaceable wall according to an exponential path curve, wherein, in a downward displacement of the wall, the wall will first undergo a predominantly vertical displacement and subsequently a more horizontal displacement, the distance between the wall and the bed base can be relatively low. are efficiently kept within predetermined limits, and are generally kept substantially constant, regardless of the height of the wall. It will be clear that with an upward movement of the wall a reverse movement will be carried out. Exponential curve in this context is also understood to mean a J-shaped curve, a parabolic curve, and a - * -shaped curve. When the wall is moved downwards, the radius of curvature of the exponential curve increases. The path curve used therefore deviates from a circle segment-shaped path that would not be applicable or at least generally undesirable if the height of the movable belt exceeds the value by approximately 65 centimeters. The increase in the radius of curvature can thereby take place gradually (continuously), but it is also conceivable that this increase in the radius of curvature is effected discontinuously in that a kink can be provided in the substantially exponential curve. The exponential path curve thus generally comprises a first path segment in which the wall will undergo essentially a vertical or strongly diagonal displacement and a second path segment which may or may not follow the first path segment in which the wall will undergo a more horizontal displacement or slightly diagonal. The directional coefficient of the web during downward displacement of the wall will first of all be relatively large (first track segment), after which it decreases increasingly (second track segment). The substantially vertical (highly diagonal) downward displacement of the wall has the purpose of displacing a (substantial) part of the side wall below the bed base, after which the more horizontal (slightly diagonal) displacement serves to create space under the bed base for ( the knees of care-giving persons, which guarantees good access for the care-giving person to the bed base. The child's bed according to the invention could also be used as a playpen. Although the child's bed according to the invention is particularly suitable for supporting children, including babies, it is also conceivable that the bed according to the invention is suitable for supporting adults, and in particular disabled persons.
    Although the walls, including the movable wall, can be substantially closed, each wall can for instance be formed by a glass or plastic plate arranged in a frame, which can be advantageous if the child's bed is used as an incubator for newly born children In a more common embodiment, the movable wall, and generally also the other walls, will be formed by a gate provided with bars.
    The movable wall preferably relates to a side wall. In a special embodiment the child's bed comprises a plurality of movable walls, wherein at least the opposite side walls are made movable. It can thereby be advantageous to detachably connect at least one wall, movable or otherwise, to the support structure, so that the child's bed is provided with a modular character, which can be particularly advantageous from the point of view of maintenance, storage and transport.
    In an advantageous embodiment, the shortest distance in the horizontal plane between the movable wall and the bed base is between 12 and 25 millimeters, regardless of the position of the movable wall relative to the bed base. By applying the aforementioned distance restriction, pinching of the child's limbs in the space between the bed base and the movable wall can be prevented as much as possible. Incidentally, it is also advantageous to apply the aforementioned distance restriction on between the bed base and any non-movable (stationary) wall of the child's bed. An additional advantage of applying this distance restriction is that the child's bed complies with the distance restrictions prescribed in international standards, such as DIN 32623.
    In one embodiment of the child's bed, the height of the movable wall is at least 80 centimeters. 80 centimeters is generally high enough to prevent small children from climbing out of the child's bed, and is therefore considered relatively safe. Moreover, the aforementioned wall height complies with current international standards, including DIN 32623, prescribed structural requirements.
    In the child's bed according to the invention, it is advantageous to have at least one guide element cooperate with an upper part of the movable wall, and at least one (other) guide element cooperate with a lower part of the movable wall. An upper part, in particular an upper side, of the displaceable wall is herein arranged for cooperation with a substantially vertical and substantially linear longitudinal guide connected to the support structure. The consequence of this is that the part cooperating with the longitudinal guide, in particular the top side, of the movable wall is only adapted to undergo a substantially vertical, linear movement. The pivotal movement of the movable wall can be realized here by applying at least one (lower) guide element which is connected to both a lower part of the movable wall and the supporting structure. This lower guide element can be formed by a rail for guiding the displaceable wall to below the bed base, but it is often practical if the (lower) guide element comprises a connecting rod (pivot arm) which is pivotally suspended about a first axis of rotation relative to the support structure and on the other hand is pivotally connected to a lower part of the movable wall. Both rotation axes are herein preferably displaceable relative to the support structure, wherein in particular the height positioning of the first rotational axis is dependent on the orientation of the displaceable wall relative to the bed base. By moving the first axis of rotation in the downward direction while pivoting the connecting rod around the first axis of rotation in the downward direction, an exponential path curve can be generated via which the movable wall can be moved. In order for the connecting rod to be able to make the above-mentioned special movement, it is advantageous for the connecting rod to form part of a multi-rod mechanism, in particular a four-rod mechanism, which is pivotally connected as such to the support structure. The multi-rod mechanism, in particular the four-rod mechanism, is thereby arranged substantially under the bed base and thus at least partially shielded. In order to be able to increase controllability of the special movement of the connecting rod, it is often advantageous if a lower transverse rod of the four-rod mechanism connected to the connecting rod is pivotally connected to a stabilizing rod which is pivotally connected to the support structure. The displacement of the movable wall can be facilitated by the use of at least one pneumatic cylinder (gas spring) which is pivotally connected to both the cross bar and the connecting rod.
    It is generally advantageous if the child's bed comprises at least one releasable locking element for locking the movable wall in the upper position. Only after the movable wall has been unlocked can the movable wall be moved downwards. The use of a locking of the movable wall is advantageous in order to prevent undesired movement of the wall, which could lead to dangerous situations. In this case, the locking is preferably designed as a two-step locking from a safety point of view for children, the locking element for instance firstly having to be actively unlocked, whereafter the movable wall has to be moved somewhat upwards, whereby final unlocking of the movable wall and thus downward movement of the movable wall is only made possible.
    The invention also relates to a child's bed, comprising: a support structure, a bed base connected to the support structure, wherein the bed base is pivotally connected on opposite ends to the support structure for changing the orientation of the bed base relative to the support structure, a plurality of Walls connected to the support structure and surrounding the bed base, wherein at least one wall is movable relative to the bed base between an upper position, in which a substantial part of the relevant wall is positioned higher than the bed base, and a lower position, in which a substantial part of the relevant wall is positioned lower than the bed base, and in which at least a part of the relevant wall is positioned under the bed base, at least one guide element connected to the support structure for guiding the movable wall between the upper position and the lower one position, and at least one locking element for locking the pivotable bed base relative to the support structure. This child's bed functions in a substantially equivalent manner than the variant versions of the child's bed described above, but the angle of inclination of the bed base relative to the horizontal is adjustable on both sides. This provides the possibility of effecting the so-called position of trendelenburg as well as the position of anti-trendelenburg. In the position of trendelenburg, the head end of the bed base is positioned lower than the foot end of the bed base, which can be advantageous, for example, if an air bubble has accidentally ended up in the child's bloodstream during injection of the child. In the anti-trendelenburg position, the foot end of the bed base is positioned lower than the head end of the bed base, which may, for example, be advantageous while the child is resting. In order to facilitate the tilting of the bed base, it is often advantageous if the child's bed comprises at least one force-supporting element, in particular a gas spring, which is connected to both the support structure and the bed base to facilitate pivoting upwardly of at least one part of the bed base. In the diagonal position, the bed base preferably encloses an angle with the horizontal between 0 ° and 45 °. In a typical (anti-) trendelenburg position, the bed base encloses an angle with the horizontal plane of approximately 12 °.
    Because both head sides of the bed base are pivotally connected to the Demand structure, it is conceivable that the bed base on both head sides (successively) is pivoted relative to the support structure, whereby the height of the bed base can be changed. In this case, even a substantially upright (vertical) displacement of the bed base relative to the support structure would be conceivable. In the desired condition of the bed base, the bed base can be locked with respect to the support structure. It is generally preferable to arrange the locking element such that upon unlocking of an end face of the bed base relative to the support structure, an opposite end face of the bed base is locked relative to the support structure. In this way a choice can only be made to pivot the bed base from the horizontal position to the trendelenburg position or the anti-trendelenburg position. In order to facilitate the operation of the at least one locking element, it is often advantageous if the at least one locking element is connected to at least one operating element.
    The invention will be elucidated on the basis of non-limitative exemplary embodiments shown in the following figures. Herein: figure 1 shows a front view of a child's bed according to the invention, in which several positions of a movable side gate of the child's bed are shown, figure 2 a perspective view of the child's bed according to figure 1, figure 3 a top view of the child's bed according to figures 1- 2, figure 4 shows a bottom perspective view of a part of the child's bed according to figures 1-3, figure 5 shows a detailed bottom perspective view of a bed base forming part of the child's bed according to figures 1-4, and figure 6 a side view of the child's bed according to figures 1 -5, in which the bed base is positioned in an anti-trendelenburg position.
    Figure 1 shows a front view of a child's bed according to the invention, in which several positions of a movable lateral side rail 2 of the child's bed are shown. The child's bed 1 also comprises a mobile support structure 3 provided with four support wheels 4, a bed base 5 supported by the support structure, and four side rails 2 surrounding the bed base 5, both lateral side rails 2 of which are movably connected to the support structure 3, and of which the end faces side rails 2 are releasably secured with the support structure 3. The height H of the movable side rails 2 is 81 centimeters in this exemplary embodiment. An upper side 2a of each movable side rail 2 cooperates with a substantially vertical guide rail 6 (see Figure 2). An underside 2b of each displaceable side rail 2 cooperates with a pivot arm 8 forming part of a multi-rod mechanism 7. In this figure 1 several successive states of one displaceable side rail 2 are shown during the displacement of the side rail 2 relative to the supporting structure 3. By application of the multi-rod mechanism 7 rotates the pivotal arm 8 during movement of the side rail 2 about a first rotation axis 9 and a second rotation axis 10, both rotation axes 9, 10 being moved simultaneously during the pivoting of the side rail 2. The path covered by both rotation axes 9, 10 during the downward movement of the side rail 2 is indicated by arrow A and arrow B. The path curve B which travels the second axis of rotation 10 corresponds to the path curve of the side rail 10 as such. It can be deduced from Figure 1 that the orbit curve B substantially corresponds to an exponential curve, or a substantially J-shaped curve, the (absolute) directional coefficient of the orbit curve B decreasing increasingly. This special movement of the side rail 2 makes it possible to prevent physical contact between the bed bottom 5 and the side rail 2 as well as entrapment of limbs in a space located between the bed bottom 5 and the side rail 2. The folding away of a part of the side rail 2 to below the bed base 5 facilitates access for a caregiver to the bed base 5. Figure 1 furthermore shows that the support structure 3 is provided with an operable blocking device 11 for the support wheels 4 to prevent undesired displacement of be able to counter the bedstead 1.
    Figure 2 shows a perspective view of the child's bed 1 according to figure 1. In this figure the linear guide rails 6 are clearly shown along which the top 2a of the side rail 2 is moved. It is also shown that opposite end sides 5a, 5b of the bed base 5 are each provided with an operating handle 12a, 12b with the aid of which the bed base 5 can be unlocked from the support structure 3 and subsequently pivoted with respect to the support structure 3 in order to position bed base 5 in a trendelenburg position (figure 3) or an anti-trendelenburg position. Furthermore, it is shown that the support structure is provided with a rotary handle 13 with the aid of which the effective length of the telescopic working legs 14 of the support structure 3, and hence the effective height of the bed base 5, can be adjusted.
    Figure 3 shows a top view of the child's bed according to figures 1 and 2. The shortest distances (in the horizontal plane) between the bed base 5 on the one hand and the side rails 2 on the other hand are indicated by arrows D 1 and D 2. Both distances D1 and D2 are smaller than 25 millimeters, as also prescribed in the DIN standard 32623, in order to prevent limb constriction.
    Figure 4 shows a perspective bottom view of a part of the child's bed 1 according to figures 1-4. In this bottom view both multi-rod mechanisms 7 can be seen which are positioned one behind the other in mirror image and which are respectively connected to one of the two movable side gates 2. Each multi-rod mechanism 7 comprises a fixed rod 16 fixed to the support structure 3, a fixed rod 16 pivotably connected to the fixed structure. rod 16 pivotable rod 17 connected, pivotable pivot arm 8 connected to fixed rod 16, a pivot rod 18 pivotally connected to pivotable rod 17 and pivot arm 8, and an additional stabilizing rod 19 pivotable to fixed rod 16 and transverse rod 18 connected. As already indicated, with the aid of the multi-rod mechanism 7, the side rail 2 can be displaced via the advantageous web curve B (see Figure 1).
    Figure 5 shows a detailed bottom perspective view of a bed base 5 forming part of the child's bed 1 according to Figures 1-4. It has been shown that each operating handle 5a, 5b is connected to a locking mechanism 20 with the aid of which two locking elements 21 can be moved for unlocking the bed base 5 relative to the support structure 3. Moreover, a displacement rod 22 will be displaced by displacement of each operating handle 5a, 5b, such that displacement of an other operating handle 5a, 5b is blocked. This makes it possible to move the bed base 5 to either the trendelenburg position or the anti-trendelenburg position. The bed base 5 is connected to a pivot arm 23 which is pivotally connected to the support structure 5.
    The tilting of the bed base 5 is facilitated by the use of a gas spring 24 arranged between the support structure 3 and the swiveling arm 23.
    Figure 6 shows a side view of the child's bed 1 according to figures 1-5, wherein all side gates 2 are positioned in an upper position, and wherein the bed base 5 is positioned in an anti-trendelenburg position. The angle α that encloses the bed base 5 with the horizontal plane is (typically) 12 °. Bringing the bed base 5 back into horizontal orientation is effected by applying sufficient downward pressure to the higher part of the bed base 5. In the horizontal state, the bottom of the bed 5 will snap onto the support structure 3 and be locked with it relative to the support structure. 3. Subsequent unlocking of the bed base 5 takes place by pulling on one of the operating handles 5 a, 5b.
    It will be clear that the invention is not limited to the exemplary embodiments shown and described here, but that within the scope of the appended claims, countless variants are possible which will be obvious to those skilled in the art.
