Best Mode of Carrying out Invention A preferred embodiment of the invention will now be described by way of example only. Although the preferred embodiment describes a shower cubicle that can be installed o o into a mobile home of the kind such a motor vehicle home that is internally fitted with cupboards, toilets, a small stove, bunks, and fittings of that nature, it should be realised that the present invention is not restricted to this embodiment. The shower cubicle as described herein could be incorporation into any portable or permanent structure in which space and floor area are limited.

The shower cubicle of the preferred embodiment comprises of a stationary compartment in the form of stationary structure 1 and a movable compartment in the form of moveable structure 2. The moveable structure 2 is pivotally connected to the stationary structure 1 about a vertical axis Y 1 The stationary structure 1, which is preferably an integral plastic unit, comprises a stationary floor 3, a rear wall 4 extending substantially along a rear edge of the floor 3, two side walls 5 and 6 coinciding with respective side edges of the floor 3, and a ceiling panel 9. The floor 3 has a plurality of ribs 7 formed thereon to assist in draining water. A recessed drainage pan 8 is also formed along the front edge of the floor 3.

CD/004461181v3 -6- The movable structure 2 comprises a curved wall panel 10 from which extends a floor 11 near its bottom edge and an upper ceiling member 12 extending from its upper edge. The wall panel 10, floor 11 and upper ceiling member 12 are preferably an integrally moulded plastic unit. The floor 11 has structural steel member 23 thereunder. A curved door 14, which is preferably made of acrylic plastic, is pivotally hinged to the movable structure 2 about vertical axis Y 2 between the upper ceiling member 12 and the floor 11.

The movable structure 2 is pivotally connected to the stationary structure 1 about axis Y 1 by means of pivot members 15 and 16. A steel triangular brace member 17 is fitted to the stationary structure 1 and is adapted to receive the upper pivot 15 which engages with the movable structure 2. The lower pivot 16 is adapted to engage with a spring 18 contained within a housing support member 19 attached to the lower portion of the stationary structure 1. The spring 18 is preferably adapted to support 90% of the weight of the movable structure 2.

In use the movable structure 2 is adapted to be movably pivoted between a standby configuration to an in-use configuration. In the standby configuration the wall panel spans between the side walls 5 and 6, and the door 14 which is pivotally connected thereto, is substantially housed within the enclosed space of the shower cubicle, as shown in Fig. 2 and Fig. 4. In order to open the shower cubicle to an in-use configuration the wall panel is pivotally rotated in a clockwise direction C as shown in Fig. 1.

000.

In the in use configuration, the floor 11 of the movable structure 2 is at the same level as the floor 3 of the stationary structure 1, and the bottom edge of the wall panel seats firmly on the floor structure of the mobile home or other space in which the shower cubicle stands. However, as the movable structure 2 is pivotally moved to the standby configuration in an anticlockwise direction, a door ramp mechanism as shown in Fig. 6, which includes a roller wheel 20 rotatably mounted to a housing 22 secured to the front edge of floor 3, and a ramp track 21 underneath the floor portion I 1, is used to lift the movable structure 2 as it is moved inwardly, in order to allow floor 11 to raise above and travel over the drainage pan 8 and the floor 3 of the stationary structure 1.

oo• ~An advantage of the present invention, is that the interior of the shower cubicle does not contain tracks or guideways which intrude into the useable space of the shower cubicle as occurs in known expansible shower cubicles. Furthermore, the shower cubicle in S-its in-use configuration provides for greater space and access through the door 14, whilst in the standby configuration, a substantial part of the upper ceiling member 12, floor 11 and CD/004461181 v3 -7door 14 are substantially stowed away or housed inside the stationary structure.

Furthermore, the curved wall panel 10 provides an aesthetically pleasing arrangement.

A further advantage of this embodiment is that the integrally moulded plastic movable structure 2 is symmetrical and may be inverted such that the upper member 12 becomes the floor 11 and vice versa. During construction the pivots 15 and 16 may be positioned near sidewall 5 rather than sidewall 6, and the shower cubicle would then become left side opening, rather than right side opening as shown in the above mentioned embodiment. In such a left side opening embodiment the brace member 17 need only be flipped over to suite the configuration, and the housing support member 19 and roller wheel 20/housing 22 flipped over and swapped around to suit such configuration.
