DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[00022] According to an embodiment of the present invention, there is provided a collapsible infant carriage 100 as shown in Figure 1A. The carriage 100 includes a pair of hinged shells 102a, 102b for collapsing together. A fastener is provided for fastening the collapsed shells 102a, 102b together so that the interior is protected from dirt and/or weather. The fastener includes a zip extending along a perimeter of the shells 102a, 102b and/or a clip for clipping together free ends of the shells 102a, 102b.

[00023] Advantageously, the carriage 100 is convertible into a hard shell suitcase as shown in Figures 1F and 1G for straightforward and safe transport. The suitcase may be a wheeled suitcase as shown in Figure 1F.

[00024] Returning to Figure 1A, the shells 102a, 102b are pivotally fastened together using a hinge 104 so that the interior can be protected from dirt and weather when collapsed. The uncollapsed shells include an upper shell 102a and a lower shell 102b. Each shell 102 is formed form durable and hard material which resists breakage, preferably plastics material. Each shell 102 is molded, and preferably injection molded. Each shell 102 is similarly shaped, with an arcuate major face to maximise internal storage and provide strength.

[00025] The carriage 100 includes a heavy-duty carriage handle 106 extending from the upper shell 102a. The height-adjustable handle 106 is axially retractable into the shell 102a. The carriage 100 also includes a canopy shelter 108, with nesting or concertinaed segments, that retracts into the upper shell 102a. The sun shelter 108 includes hoop frames 107, pivoting about hinge 104 and supporting flaccid sheet material 109, preferably fabric.

[00026] Turning to Figure 1B, the carriage 100 also includes a pair of spaced apart wind shelters 110, between which an infant is located and fastened to the shells 102a 102b. The side shelters 110 also include one or more straight frames 111, pivoting about hinge 104 and supporting flaccid sheet material 113, and retracting or folding into the shells 102a 102b. The side shelters 110 also restrain the open pivoting of the shells 102a 102b to a maximum limit.

[00027] The carriage 100 further includes an underside storage compartment 112 for extending from the lower shell 102b. The storage compartment 112 includes a pivotable panel 114, and a pair of spaced flanks 116 extending from the panel 114. The panel 114 is hard and durable plastic, and may or may not form part of the lower shell 102b. The tapered flanks 116 are formed from flaccid sheet material, preferably fabric. Advantageously, the storage compartment 112 is also readily accessible when the shells 102a 102b are collapsed to form a suitcase (Fig. 1F).

[00028] The carriage 100 further includes a reclining infant backrest 118 for pivotally extending from the surrounding remainder of the upper shell 102a. The backrest 118 is retractable and extends rearwardly when the shells 102a 102b are uncollapsed. The backrest 118 includes a pivoting panel 120, and a pair of spaced flanks 122 extending from the panel 120. The panel 120 is hard and durable plastic, forming part of the upper shell 102a. The tapered flanks 122 are formed from flaccid sheet material, preferably fabric.

[00029] The carriage 100 also includes an internal seat (not shown) pivotally mounted to the shells 102a 102b between the ribs 111, and an internal footrest in the lower shell 102b. In one embodiment, the seat and footrest can be formed from flaccid sheet material, preferably fabric.

[00030] Turning to Figure 1C, the carriage 100 includes a rear wheel mount 124 to which two larger rear wheels 126 are fastened. The wheel mount 124 is pivotally mounted to the shells 102a 102b about the hinge 104. The cantilevered wheel mount 124 extends obliquely from the shells 102a 102b, and can be retracted so that legs receive the collapsed shells 102a, 102b (Fig. 1E).

[00031] The carriage 100 also includes two smaller front wheels 128. The front wheels 128 are pivotally mounted to the lower shell 102b. The front wheels 128 can pivot through 360 degrees about a vertical axis as well as rotate about a horizontal axis, whereas the rear wheels 126 are confined to only rotating about a horizontal axis. Both the rear wheels 126 and front wheels 128 are readily releasable, and can be stored in the collapsed shells 102a, 102b for vehicular transport (Fig. 1G).

[00032] Turing to Figure 1F, the carriage 100 also includes a suitcase handle 130 extending from the lower shell 102b. The height-adjustable handle 130 is axially retractable into the shell 102b, and need not support as much weight as the carriage handle 106. The handles 106, 130 are opposed.

[00033] A method for collapsing the infant carriage 100 is now described with reference to Figures 1A to 1G.

[00034] Initially in Figure 1A, the infant carriage 100 is in an uncollapsed or erected configuration. The shells 102a 102b are open, all parts are fully extended, the fabric seat is substantially aligned with and extends between near horizontal frames 111.

[00035] In Figure 1B, the canopy shelter 108 is retracted into the upper shell 102a.

[00036] In Figure 1C, the carriage handle 106 is pushed into the upper shell 102a. The underside storage compartment 112 and backrest 118 are also retracted.

[00037] In Figure 1D, the top shell 102a is pivoted toward the bottom shell 102b so that the shells 102a, 102b are collapsed together for fastening with a zipper or clip.

[00038] In Figure 1E, the wheel mount 124 is pivotally retracted to receive the collapsed shells 102a, 102b. The resulting wheeled suitcase can stand upright.

[00039] In Figure 1F, the suitcase handle 130 can be extended for wheeling around. The storage compartment 112 can conveniently still be opened and accessed for stowing or retrieving items.

[00040] In Figure 1G, the wheels 126, 128 are removed and stored in the collapsed shells 102a, 102b, via either the storage compartment 112 which is then again retracted or through slightly pivoting the shells 102a, 102b apart before collapsing again and fastening. The collapsed carrier 100 is super compact for shipping and storage, with no exposed parts and therefore highly resistant to breakage.

[00041] A person skilled in the art will appreciate that many embodiments and variations can be made without departing from the ambit of the present invention.

[00042] In one embodiment, the canopy shelter 108 and/or side shelters 110 are releasable.

[00043] In compliance with the statute, the invention has been described in language more or less specific to structural or methodical features. It is to be understood that the invention is not limited to specific features shown or described since the means herein described comprises preferred forms of putting the invention into effect. The invention is, therefore, claimed in any of its forms or modifications within the proper scope of the appended claims appropriately interpreted by those skilled in the art.
