Definitions

• This invention has to do with cots for babies.
• Particular issues addressed in the application include foldable wall arrangements for a cot, an optional foldable stand, and adaptation useful for arrangements in which the cot is to be positioned closely adjacent a parent bed.
• a cot comprising a sleeping base, opposed side walls and opposed end walls mounted to the sleeping base.
• Each wall has a stable upright condition, in which in combination the walls form an upstanding surround for the cot.
• Each wall is releasable from the upright condition.
• They are discrete, independently movable walls.
• the end walls are mounted pivotally to (or relative to) the sleeping base so that when released they can pivot inwardly to overlie the sleeping base.
• the released side walls can also lie on the base, retained beneath the end walls.
• One or both of the side walls is desirably pivotally mounted to the sleeping base, so that when released it can pivot in to lie on the base and the end walls then be pivoted in to overlie both.
• the cot is typically oblong in plan,- since the end walls and side walls are typically of the same or similar heights, usually the side walls overlap one another in the folded-down condition whereas the end walls do not.
• the inner (forward) faces of the end walls are recessed to enhance their containment and/or protection of the top of the sleeping base and of objects on it.
• the sleeping base will typically carry or include a mattress, and there may be loose bedding such as a quilt or blanket.
• the released side walls are also contained.
• a preferred form of end wall has side edges which are forwardly curved or angled over most or all of their height.
• a preferred form of end wall is a generally rigid shell, desirably of closed construction (rather than an open lattice, grille or mesh) .
• one or both side walls be of lighter and/or more open construction than the end walls (e.g. comprising mesh, grille or lattice) .
• the sleeping base may comprise a support board for a mattress, with thicker reinforcing portions extending along its side edges. Pivot engagements at each side of each end wall may conveniently be made with these side reinforcing portions .
• a cot has a support base (which may be a sleeping base e.g. as described in other aspects herein, or may be a support platform of a discrete stand, on which a cot having its own sleeping base is to be supported) .
• first and second extensible leg arrangements are provided at respective first and second ends of the support base.
• the corresponding leg arrangement has a main leg member and a support strut having a lower end connected pivotally at an intermediate point of the main leg member.
• the top end of the support strut is connected to the support base at a fixed pivot proximal to the corresponding end of the support base.
• the top end of the main leg member is connected to the support base at a pivot connection which is longitudinally slideable along a track relative to the support base, over a range of positions, and which is further from the respective end of the support base than the fixed top end of the strut.
• the lower part of the main leg member extends beyond the intermediate point to a foot having transversely-spaced extremities, so that the cot can be stably supported on the two feet of the first and second leg arrangements .
• the leg and strut lie generally parallel against the base, with the top slider at its position most remote from the end.
• the top slider moves along its track out towards the end, the angle between leg and strut closes and the intermediate pivot point also moves (more slowly) out towards the end.
• the longitudinal position of the foot beneath the support base varies little or not at all so that, by locking the slider at a selected position along its track, a desired height can be chosen without compromising the longitudinal footprint of the first and second legs.
• each folded main leg member should leave clearance for the extreme of the slider movement at the top of the other main leg member, and generally be not more than complementary in shape relative to the other leg member in plan, so as to avoid superimposition .
• the slider track for each main leg member is positioned towards a respective side of the support base, and the top of the leg member approaching the slider connection is narrow compared with the foot at the other end of the leg member.
• a suitable corresponding shape for the main leg member (in folded plan) is an W L" shape, or a shape tapering from bottom to top, e.g. triangular, (such as a right-angled triangular shape, with the respective hypotenuses of the first and second legs approaching one another when folded down.
• the struts again it is desired to achieve flat folding so, if they have appreciable thickness, their plan shapes do not extend beyond complementarity with the main leg member shapes, i.e. they lie in clearances thereof in the folded condition.
• the strut may be positioned and shaped to lie within an internal opening (e.g. a through-aperture) of the main leg member when folded flat .
• the slider pivot of each main leg has means for locking its position on the corresponding track to fix the height of the leg.
• Lockable positions may be available in a continuous range, or at a limited number of predetermined positions along the track.
• the locking means are not critical, but preferably the slider has a releasable clamp engageable with the track e.g. so that a continuous adjustment is possible.
• the track may be marked with indicia to help select the height.
• a movable marker e.g. another slider
• the slider is operable from the top or side of the support base for user convenience.
• the support base is a support platform for a separate cot and the sliders are exposed for operation at its top surface but covered when the cot is in position on top so that the mechanism is not inadvertently moved or released.
• the construction may have a discrete stand which provides a support top e.g. a platform, on which the cot is positioned.
• the cot should connect securely to the support, so that it is not inadvertently pushed or tilted off, and yet is easy to put in place.
• this can be by means of plural projections of the cot underside which fit closely onto, into or around corresponding holes, recesses, clearances or extremities of the support platform.
• the reverse arrangement i.e. projections upwardly from the support platform may be used but is less preferred.
• Pegs and/or holes may have entry tapers to facilitate insertion by reducing criticality of positioning.
• bottom parts of opposed surround walls of the cot e.g. opposed end walls, project down below the sleeping base level and that these downward projections fit around correspondingly shaped edges of the support base.
• Such constructions are easy for a user to sight into place, and may in themselves facilitate alignment of supplementary engagements such as pegs and holes .
• end walls of the preferred construction defined above having forwardly-projecting side flanges, provide a positive and easily-fitted engagement onto complementariIy-shaped end edges of a support platform.
• Another aspect relates to the provision of one or more side walls for a cot, where a side wall can be released from its upright condition and pivoted down to a generally horizontal position, either inwards onto the sleeping base or outwards, e.g. to bridge a gap to a parent bed as described elsewhere herein.
• such a function requires a pivotal mounting at the bottom of the side wall - which may engage the sleeping base, a static frame, or a supplementary mounting attached to either of these - and one or more releasable fasteners or engagements which hold the wall in the upright condition.
• the exact form is not critical, provided that it is simple, effective and safe for children. In particular, release should involve a combination of thought, coordination and action to operate the mechanism which is selected to be beyond young children.
• a preferred type of fastener which is an independent aspect of our proposals here in the context of cot side walls, has complementary releasably interlockable components, one on each of the side wall and end wall/frame component, with one of them - preferably that on a side wall - mounted elastically so that it must be pulled against resilient force to bring the components to a releasable position.
• the elastic resilience may be provided by deformation of an elastomeric material, e.g. by mounting one of the interlock members to the side wall or other component via a piece of elastic material such as elasticised fabric.
• a desirable interlock has an aperture in one member and on the other member a projecting element with a head shaped to fit relatively closely in the aperture and a neck shaped to fit relatively loosely in the aperture, at least, in the direction of extension of an elastic connector as mentioned above. After stretching the connector to pass the head through the aperture for locking, elastic recovery hooks it behind the wall surrounding the aperture. To release it, the user must pull the head out against the elasticity to the appropriate alignment with the aperture so that it can be withdrawn. The more closely shaped the head and aperture, the more critical - and hence childproof - it is to match their positions for release.
• a separate proposal here is for a release mechanism operating at the bottom of the side wall, in which a pivot mechanism connecting between the bottom of the side wall and the sleeping base (or adjacent frame, or end wall) has a locked condition in which it holds the side wall upright and a released condition in which the side wall can pivot down as mentioned previously.
• the mechanism is shifted from the locked condition to the released condition by a bodily - and preferably translational - movement of the side wall itself relative to the sleeping base.
• the mechanism is released by lifting the side wall from a downward rest condition, which is the locked condition.
• gravity helps to keep it locked.
• the pivot mechanism may incorporate first and second interfitting components or formations, one on each of the side wall and the adjacent structure, which in a first alignment engage one another so as to prevent rotation of one component relative to the other, and in a second alignment where one is rotatable around the pivot's operational axis relative to the other.
• first and second interfitting components or formations one on each of the side wall and the adjacent structure, which in a first alignment engage one another so as to prevent rotation of one component relative to the other, and in a second alignment where one is rotatable around the pivot's operational axis relative to the other.
• a longitudinal bar, rail or edge at or near the bottom of the side wall may drop into a trough, channel or other detent means below a pivot engagement which • ⁇ allows vertical play, so that the upright side wall can be dropped into or lifted out of the engagement which holds it upright .
• one of the two components is tubular, with a tube axis desirably held aligned with the side wall length, and having a slot cross- section, desirably oriented vertically (i.e. higher than it is wide), and with rigid opposed side walls.
• the other component is a rigid bar with a free end projecting into the mouth of the slot tube, and mounted pivotally to its own structural component so that the free end can swing in a limited range within the slot tube, in the slot plane thereof.
• Dropside cots are in themselves very well known. To facilitate access to the baby, it has been known for many decades for one side of the cot to be removable from or displaceable in the structure, either by lifting it out, pivoting it out gate-wise or releasing it to slide downwardly on a frame (in the case where a cot has a tall support frame) .
• a displaceable side is relevant
• the cot is to be used in a co-sleeping arrangement with the cot positioned close up against the side of a parent bed, and the mattresses of the two at the same level.
• a cot side wall at the parent bed side can prevent the baby from rolling onto the parent mattress, and prevent a sleeping parent from inadvertently throwing a limb onto the cot area.
• the parent is awake, however, there may be value in removing or displacing that side wall, e.g. to enhance companionship and feeling of security for the baby or parent, or to facilitate adjusting the bed clothes, or the baby's position or clothing, in the cot area.
• Some parents may prefer to keep this wall removed all the time.
• the side wall in question be pivotably mounted at or adjacent the cot sleeping base level so that it can be pivoted down and outwardly to lie on the parent bed.
• This offers various advantages. It bridges the gap which is likely to exist, whatever the construction of parent bed or cot, between the edges of the parent mattress and the cot mattress even when the two are held as close together as possible.
• a sympathetic surface material e.g. a fabric covering on the side wall
• this "drawbridge" can safely and comfortably be left in place. Because of the pivot action, the gap is effectively bridged even if the heights of the two mattresses are not exactly matched, and the bridge is held against sliding out of place.
• the pivot of the side wall may be provided by a mechanism as proposed above in 4 (B) .
• a side wall can itself be folded along a fold line at an intermediate height of the side wall, preferably at about half-height and in general desirably between one-third and two-thirds height of the side wall, so that an upper part of the side wall can be folded down while leaving the lower part of the side wall erect.
• Providing this intermediate height has particular value in that it improves ease of access into the cot space from outside, while preserving some barrier e.g. to prevent the baby from rolling out onto the parent bed in a co-sleeping arrangement.
• the intermediate height option is also attractive in offering the possibility for a parent easily to reach an arm into the cot area e.g. to comfort the baby, without having to remove all barrier between the two sleeping areas .
• the folding mechanism of the side wall permits the top part of the wall to be folded only outwardly relative to the lower .
• one or both side walls of the cot in the form of rigid frame elements forming a frame defining one or more openings occupied by flexible fabric material e.g. cloth or mesh, or a combination of these.
• a preferred version uses frames comprising stiff rods of metal (or perhaps tough plastics) shaped into open hoops e.g. of generally rectangular form. These can be covered with fabric coverings.
• One convenient form has the fabric covering as an envelope with opposed walls into which the frame is inserted.
• the fabric envelope may be removable for cleaning.
• at least one central region of a side wall is transparent, e.g. mesh.
• a border of closed fabric may extend around the frame elements to provide dimensional strength and durability, with a central "window" for transparency.
• Cots as proposed herein may in general be secured to a parent bed by any suitable means, such as e.g. straps, and the present proposals are not particularly limited in this respect .
• a securement device which is a rigid L-section member, having a first flat arm of the L which lies under the parent mattress so that the second arm stands upright next to the mattress.
• the upstanding arm of the L has one or more upstanding projections - preferably plural longitudinally-spaced projections - which are engageable with the cot e.g. by passing up into or through corresponding openings or recesses thereof, e.g. through one or more slots extending longitudinally along the side of the cot.
• the retaining projection (s) can be formed as a simple integral part of a flat or plate-form member, no moving parts are needed and the construction is simple and economical. It is useable with many kinds of bed, even where the mattress is partly encased by a surround wall .
• a preferred refinement has both arms of the L provided with corresponding projections so that either can be used in the upstanding position to retain the crib, the two arms being of different length for use with beds of different heights.

• the frames of the side walls are shown, so that their construction can be understood.
• the finished product they are covered with fabric covers as explained below with reference to Figs. 15 to 17.
• the main elements of the stand 10 are a top platform 9 (see Fig. 3) on which the sleeping base 2 of the cot rests, and a pair of pivoted legs 7 which are extensible to a desired height.
• the sleeping base 2 with mattress 21 removed comprises a flat board 23 with longitudinal reinforcing edge members 22. These may all be wood.
• the end walls 3 are single shaped sheets of closed rigid material e.g. of plywood, with handle openings 31 at the top centre and side edges which curve forwardly as flanges 32.
• the side flanges 32 are connected to the side members 22 of the base by pivots 33 at the corners.
• Each pivot 33 has an axle pin 330 which also provides a mounting for a side wall pivot locking mechanism described later.
• the bottom edges 34 of the end walls 3 project below the sleeping base and lie in a plane so that, as seen in Figs. 2 and 5, they act as support feet for the cot when it rests by itself on a flat surface.
• Catches 26 are provided at the centre at each end of the sleeping base board 23; each is a strong flexible plastics element having a projecting lug 28 engageable in a corresponding recess in the inner face of the end wall 3 , as seen in Figs . 2 and 5, to prevent the end wall 3 from pivoting relative to the base.
• a flexible actuating area 29 of the catches 26 their retaining lugs 28 are swung out of engagement and the end walls 3 can be folded forward to the position seen in Fig. 7.
• the catch actuating areas are recessed into the board 23 and lie under the mattress, so that they can be released only by lifting the mattress and deliberate pressing.
• each end wall side flange 32 is a shaped recess 36 forming one part of a top fastener arrangement shown in Fig. 6. Because the part of the fastener 58 on the side wall is incorporated in the fabric element thereof, it is not seen in the other figures here .
• An elastic fabric strip or tab 581 is sewn to the top corner of each side wall, and carries a rigid interlock formation 582 having an enlarged circular "mushroom" head 583 on a stem 584.
• the diameter of the circular head 583 is only slightly less than the height of the slot 36. Because the elastic holds the formation hooked into the forward end of the slot 36, it can be released only by extension against the elastic force while at the same time positioning the head 583 carefully in relation to the slot 36 so that it can be withdrawn.
• the two side walls 4,5 are attached to the end pivot axes 330 by mechanisms (described below) which allow the wall to pivot inwardly or outwardly.
• the side walls are released and pivoted inwardly to lie overlapping on the mattress.
• the end walls 3 can then pivot inwardly and, because of their curved shape with the end flanges 32, securely enclose the space beneath them with the mattress and side walls.
• Figs. 9 and 10 are for the simple side wall 4
• Figs. 11 to 13 are for the folding side wall 5 but the pivot mechanism is the same for both.
• Each side wall has a respective frame 41,51 of generally open form made of simple round metal rods bent to form the requisite rectangular closed shapes.
• a fabric cover 42,52 is fitted over each side wall frame.
• the fabric cover has a strong closed fabric surround 421,521 into which a window 422,522 of mesh is sewn.
• the cover 42,52 is formed as an envelope open at its bottom edge, so that it can be slid down over the frame. It may then be closed at its bottom end by hook-and-loop fasteners, buttons, press studs or the like.
• the wall is supported by its bottom frame element which is an elongate tube 11 of slot cross-section, with the long axis of the slot in the plane of the wall, i.e. vertical when the wall is vertical.
• the other members of the frame above have their lower ends fixed down into the top of the tube 11.
• the tube 11 is supported on the cot at each end through a moveable interlock member 12 having an eye 121 pivotally mounted to the sleeping base (in this example, on the same axle pin 330 as the end wall mountings 33) and a free rod end 122 projecting as a pivot bar into the open mouth 111 of the tube 11.
• Section view Fig. 10 shows the complete shape of the interlock element 12, which is made from simple round stock. Its diameter is only slightly less than the width (narrow axis) of the tube slot.
• the foldable wall 5 has its frame hinged at half-height so that it can be folded down. This is achieved by a plastic friction hinge fitting 53, one at each end of the wall, seen in Figs. 1, 2 and 13 in more detail in Fig. 14.
• the metal rod frame is formed as a complete lower loop 511, with one of the hinge elements 53 slid onto it at each end of its upper span, and a further upper loop 512 forming the upper area of the wall, and whose inturned lower ends also fit into the hinge elements.
• Each hinge element 53 has a tight-fitting bore for the respective frame rod piece.
• the outer mouths of these are longitudinally staggered and the upper and lower frames are slightly different width, so that (as indicated in Fig. 13) the upper and lower rods 512,511 can nest in next to one another and fold to a near-flat condition.
• each hinge element has a rear stop plate 532, extending behind the elbows 514,513 of the upper and lower frame elements, which prevents the top part 512 from being folded inwardly relative to the lower part. Generally it is undesirable to allow the wall to fold into and obstruct the cot interior.
• Fig. 15 shows the foldable wall 5 folded down while held in the upright condition by the locking base pivot, the top fasteners having been undone to enable folding.
• Figs. 16 and 17 show the half-height folded wall 5 pivoted outwardly, and in Fig. 17 resting on the mattress of a parent bed to provide a bridge in a co-sleeping arrangement. With the wall at half-height in this arrangement, there is an intermediate level of access for a parent while the baby cannot roll out.
• the stand is described with reference to Figs. 3 and 18 to 21.
• the whole stand is made from plywood.
• the underside of the sleeping base board 23 carries four downwardly-projecting pegs 27 with rounded ends, which are for engagement with the support platform 9.
• the platform 9 is generally rectangular, and has end edge extremities 98 shaped to conform to the inner contour of the cot end walls 3 where these project down, so that the cot 1 can be positioned easily by moving one end wall 3 into engagement with a platform end 98 and then lowering the other end. This also registers the downward pegs 27 on the cot with their fitting holes 97 on the platform 9.
• the pegs have rounded ends and annular base enlargements 271, with corresponding enlarged entry regions of the openings 97 on the platform, so that engagement can begin with approximate alignment and move to a close fit. In combination with adequate depth, this prevents a sideways push from tilting the cot off the platform.
• the stand has a pair of legs 7 each of generally triangular form, with a central triangular opening 71, a horizontal bottom member 72 constituting a wide foot for the leg - the same width as the cot - and inner and outer uprights 73 tapering gradually together in the triangular form. These meet at a top portion 74 which connects to a slider 75.
• the triangles are substantially right-angled (rather than isosceles) so that although their feet are centred their top portions 74 connect at respective opposite sides of the platform 9.
• An elongate slot track 91 extends along each side of the platform 9 and receives the slider which, as seen in Fig. 19, takes the form of a two-part releasable clamp having upper and lower parts 751,752.
• a cam locking lever 753 By the action of a cam locking lever 753, these can either grip a flange 911 running along the track 91 or be released to slide freely along the track 91.
• a transverse pivot 78 connects to the lower end of a support strut 8 half the length of the leg.
• the upper end of the support strut 8 is connected to a fixed pivot 81, central near the end of the platform 9.
• the action of the legs will be apparent from the drawings and the previous general description.
• the legs 7 and their struts 8 take the form seen in Figs. 20 and 21.
• the struts are shaped as triangles which fit within the triangular openings 71 of the legs 7.
• the triangle of one leg 7 complements the triangle of the other when folded flat, as seen in Fig. 21.
• the whole leg arrangement lies in a single layer thickness of the wood used to make it.
• both legs 7 and their struts might be cut from a single sheet of wood to reduce waste.
• the leg 7 may be swung down to any desired height, and the slider secured to hold the selected position. This may be to adjust to match the height of a parent bed.
• the legs are independent, so a slight tilt can be provided if wished.
• the slider/strut mechanism maintains the longitudinal footprint of the pair of legs 7 irrespective of the particular height chosen.
• the slide levers 753 are accessible only from the top and are completely covered when the cot is in place. They cannot then accidentally be released e.g. by a child.
• the combined stand and cot can be folded flat together as shown in Fig. 21 e.g. for putting in a carrying case.
• Figs. 22 and 23 show an L-shaped connector 90, having two longitudinally-spaced L members 91 connected by rigid rods 92.
• Each L member 91 has a longer flat arm *a" and a shorter flat arm w b" .
• Either the long side or the short side can lie on the parent bed base 101, as shown in these two figures.
• the parent mattress (not shown) is lain on top to hold it securely in orientation.
• a supplementary strap 95 may tie it through to the other side of the bed, as known per se.
• the upstanding projections can then be used to engage longitudinal clearances formed in the cot .
