## Background
This application is the U.S. National Phase of International Application
PCT/GB2007/003720, filed Oct. 2, 2007, which designated the U.S. PCT/GB2007/003720 claims priority to British Application No. 0619582.0 filed Oct. 2, 2006. The entire content of these applications are incorporated herein by reference.
This invention relates to infant accommodation apparatus. Numerous types of apparatus for accommodating and/or entertaining infants are known. For example, playpens comprise an enclosure wall supported on the floor within which an infant is placed. Another known apparatus comprises a pair of soft foam semi-circles secured together in order to define a circular area for accommodating an infant.
BACKGROUND OF THE INVENTION
GB2284546 describes an apparatus which comprises an inflatable annular body within which an infant can be accommodated. GB2318050 describes an apparatus which comprises an inflatable annular body and a frame means extending above the annular body for stimulating an infant positioned within the inflatable annular body.
There are problems associated with the inflatable annular body described in the aforementioned document. For example, it has a large volume which is costly to produce because it uses a large amount of plastics material to define the inflatable member; and, furthermore, it takes a relatively long time to inflate, particularly if it is “blown up” manually by a person.
Additionally, the annular body provides little lateral support for an infant positioned within it and, consequently, the infant could roll over in some circumstances if it moves.
The frame means of GB2318050 is difficult to assemble and is relatively weak. Consequently, there is a risk of inadvertent collapse in use. Furthermore, only relatively light stimulating means can be suspended from a few predetermined positions on the frame means.

DESCRIPTION OF PREFERRED EMBODIMENTS
The infant accommodation apparatus 2 comprises an inflatable support device 4 and a framework 6 which abuts and extends over the device 4 and includes toys (not shown) arranged to stimulate, for example to visually stimulate, an infant accommodated within an accommodation region 7 of the device.
The apparatus 2 is described in greater detail below.
The support device 4 comprises an inner inflatable plastics member 8 and an outer removable fabric cover 12 which is arranged to completely enclose the member 8. The support device incorporates a padded base part 14 upon which the infant may lie, kneel or sit when the accommodation region 7.
Referring to FIG. 3, the plastics member 8 includes an enclosure wall 10 which defines an opening 12 which, when member 8 is inflated, define the infant accommodation region 7. The enclosure wall 10 has respective parallel inner and outer walls 13, 14 in the shape of modified equilateral triangles. This is illustrated in FIG. 6 wherein three convex arcs 16 are shown extending between adjacent apexes 18 of an equilateral triangular in order to form the shape of the outer wall 15. Thus, outer wall 14 of the member 8 may be regarded as being of a modified triangular shape having three curved apex regions 20 each of which has a radius of curvature which is less than the radius of curvature of the outer wall at positions between the apex regions 20. The inner wall 13 corresponds in shape to that of the outer wall 14 and so the opening 12 defined by the inner wall 13 comprises three regions 22 having a radius of curvature which is less than the radius of curvature of regions of the opening between the apex regions.
The shape of the plastics member 8 (and consequently the infant accommodation region 7) leads to several advantages described herein. One of these is that it can be made using less plastics material and has a lower volume when inflated compared to an equivalent ring shaped plastic member, for example of the type described in GB231805A and GB2284546B. This is illustrated in FIG. 7 wherein the plastics member 8 of FIG. 3 in a deflated state is shown superimposed upon a ring-shaped member having a maximum diameter which is the same as the plastics member. It will be noted that member 8 does not include three areas 22 and it will therefore be appreciated that this leads to provides a significant reduction in the area of plastics material needed to make member 8 and also the volume of air needed to inflate it, compared to the ring-shaped member.
The plastics member 8 is preferably made from a plastics material which does not contain phthalates.
The fabric cover 12 is shaped to snugly receive the plastics member 8 so that when the member 8 is arranged within it the shape of the support device 4 substantially corresponds to that of the plastic member 8, as shown in FIGS. 4 and 5. Thus, the region 7 is in the shape of a modified equilateral triangle with apex regions 30 having a lower radius of curvature compared to the radius of curvature of regions between the apex regions.
The cover 12 includes a zip 32 (FIG. 1) arranged to define an opening through which the plastics member 8, in a deflated state, may be inserted for engagement with the cover. The member 8 may then be inflated to define the arrangement of FIG. 1. It should be appreciated that the padded base 14 of FIG. 7 is not secured to the underlying fabric 34 so that the plastic member 8 can pass between base 14 and fabric 34 when it is being positioned within the cover.
When assembled, the support device 4 defines a safe, supportive environment for an infant which may be positioned with its head/shoulders resting upon one of apex regions 30 and its torso/legs being positioned generally within accommodation region 7. It is found that the arrangement of the apex regions 30 with lower radii of curvature helps laterally support the infant's head and/or shoulders and so the infant is held more stably by the support device in comparison to similar ring-shaped devices.
The inflatable support device 4 may be used as a stand alone device for accommodating an infant or may be used in conjunction with the framework 6.
Referring to FIGS. 8 to 10, the framework 6 is in the form of a tripod defined by three legs 40 secured to a central boss 42. The boss 42 comprises a body 44 which includes three radially extending, at 120° intervals, key-hole shaped sockets 46 which are arranged to slidably engage correspondingly shaped ends 48 defined at respective ends of upper leg members 50. The body 44 includes an internally screw-threaded upwardly open central socket 52 which is arranged to engage a screw-threaded bolt 56 which extends centrally from an underside face of a securement plate 58. The plate 58 is arranged to be engaged with body 44 for securing the ends 48 of the three leg members 50 to the boss 42.
Each leg 40 includes an upper curved leg member 50 having respective ends 48 and a substantially oval-cross-section end 60 which is arranged to be engaged in leg sleeve member 62 which comprises an oval-cross-section tube. A lower curved leg member 64 includes an oval-cross-section end 66 which is arranged to engage sleeve member 62. Thus, each leg 40 includes members 50, 62 and 64 which are arranged to be releasably slideably engaged with one another.
Members 50, 62 and 64 and boss 42 of the framework are made from a rigid plastics material which does not significantly bend under normal loads. Thus, the framework 6 is strong and supportive. It may support a range of stimulation means for stimulating an infant. In some cases, stimulation means may be fixed between two or three of the leg members 50 using hook and eye (e.g. Velcro) fastenings. This could be used to position the stimulation means towards the top of the framework. Alternatively and/or additionally, stimulation means may be secured to hooks 70 provided on each sleeve member 62 or stimulations means may be secured to two or three hooks 70 and extend therebetween. Nevertheless, it should be appreciated that the framework is arranged such that stimulation means may be arranged in numerous positions so that an optimum position may be selected for stimulating an infant arranged within infant accommodation region 7.
An alternative framework for use with the support device 4 may be as described in GB2318050.
A specific example of how a stimulation means may be secured in position is illustrated in FIGS. 11 and 12. Referring to FIG. 11 a fabric sleeve 100 is generally rectangular and has two tabs 102 at opposing ends, wherein the tabs 102 include elongate openings 104. The fabric sleeve is decorated with an attractive design. Referring to FIG. 12, the sleeve 100 is shown positioned around a leg 40 of the framework with respective tabs 102 and their associated openings 104 being superimposed. A hook 110 extends through the superimposed openings 104 and hangs downwardly and thereby serves to hold the tabs 102 together and to secure sleeve 100 in position on the leg 40. When so arranged, the sleeve 100 remains in position (and does not slide under gravity) due to friction between it and the leg 40. At its lower end 112 the hook 100 is arranged upwardly to define a hook element which can be engaged in an opening 115 in a toy 116.
The framework 6 cooperates in use with support device 4 as shown in FIGS. 1 and 2. More particularly, legs 40 are arranged adjacent regions which extend between the apex regions 80 (FIG. 2) of the support device. Since the framework 6 is self-supporting it need not be secured to the support device 4. Once positioned as described, an infant can easily be positioned with its head/shoulders on one of the apex regions 30 and stimulation means associated with the framework 6 suitably positioned to stimulate the infant.
Thus, the infant accommodation apparatus described can be made relatively cheaply; can be assembled and inflated easily; provides a sturdy assembly; allows an infant to be easily positioned within it in a safe, supportive environment; and allows stimulation means to be arranged in numerous positions for stimulating and interacting with the infant.
The invention is not restricted to the details of the foregoing embodiment(s). The invention extends to any novel one, or any novel combination, of the features disclosed in this specification (including any accompanying claims, abstract and drawings), or to any novel one, or any novel combination, of the steps of any method or process so disclosed.
