DETAILED DESCRIPTION OF THE INVENTION

[0047] 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 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.

[0048] 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 Y1. 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.

[0049] The movable structure 2 comprises a curved wall or closure panel 10 from which extends a floor or floor portion 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 Y2 between the upper ceiling member 12 and the floor 11.

[0050] The movable structure 2 is pivotally connected to the stationary structure 1 about axis Y1 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.

[0051] 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 10 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 10 is pivotally rotated in a clockwise direction C as shown in FIG. 1.

[0052] 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 10 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 11, 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.

[0053] 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 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 door 14 are substantially stowed away or housed inside the stationary structure. Furthermore, the curved wall panel 10 provides an aesthetically pleasing arrangement.

[0054] 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.

[0055] The apparatus in accordance with the second preferred embodiment of the present invention is shown in FIG. 7 and FIG. 8. Referring first to FIG. 7, the apparatus includes a compartment 100. This compartment 100 comprises a forward compartment when in use in a shower cubicle and will be referred to hereinafter as the forward compartment 100. The forward compartment 100 also comprises a floor 101 and a ceiling 102. The forward compartment 100 also comprises a curved wall or closure panel 103 and an entry door 104. Entry door 104 is pivotally mounted along vertical axis 105 to the forward compartment 100. The ceiling 102 of the forward compartment 100 is provided with bracket 106 fixed thereto. Bracket 106 includes upwardly extending projection 107. The function of upwardly extending projection 107 will be described in more detail hereunder.

[0056] Turning now to FIG. 8, which shows the forward compartment of FIG. 7 apart and in line for assembly, as can be seen, the floor 101 of the forward compartment comprises a moulded plastic unit. A base support 108 is fixed to the underside of floor 101 by means of suitable fixing means 109. The base support is preferably made from aluminium plate and is designed to increase the strength of the floor 101.

[0057] The wall 103 includes an outer panel 103A and an inner panel 103B. Outer panel 103A and inner panel 103B are fixed to the floor 101 by inserting the respective lower edges thereof into suitable shaped receiving means formed in the floor 101. Similarly, the upper edges of outer panel 103A and inner panel 103B are received in suitable shaped receiving means formed in the ceiling 102.

[0058] The forward compartment 100 also includes a pivot edge extrusion 110 that forms one of the vertical edges of the forward compartment 100. Pivot edge extrusion 110 includes an opening 111 which receives a projecting member formed on the lower connecting bracket. This will be described in further detail hereunder.

[0059] The forward compartment 100 also includes entry door 104. Entry door 104 is attached to entry door extrusion 112. Entry door extrusion 112 receives entry door pivot assembly 113. Lower entry door pivot assembly 113 engages hole 114 formed in the floor 101. Similarly, the upper entry door pivot assembly is received in a similar hole (not shown) formed in ceiling 102. By this mechanism, the entry door 104 is pivotally mounted to the forward compartment 100. Effectively, entry door 104 is hingedly mounted to the forward compartment 100. The entry door is also provided with a door seal 115.

[0060] The apparatus of the second preferred embodiment of the present invention also includes lower bracket 116. Lower bracket 116 is designed to be fixed to the lower most forward edge of a stationary compartment of the type shown in FIG. 9 and FIG. 10. Lower bracket 116 includes an upwardly extending projection 117. Upwardly extending projection 117 is designed to fit into opening 111 on pivot edge extrusion 110 such that the pivot edge extrusion 110 becomes pivotally mounted to lower bracket 116. It will be understood that this results in the forward compartment 100 being pivotally mounted to the lower bracket 116.

[0061] The apparatus may further include an upper bracket 118 that is affixed to an upper part of the shower cubicle. Upper bracket 118 includes aperture 119 for receiving upwardly extending projection 107 on bracket 106. A top pivot bearing assembly 120 is preferably fitted to upwardly extending projection 107 to assist in smooth pivotal operation of the forward enclosure 100.

[0062] As will be appreciated, the forward compartment 100 is pivotally mounted to both the lower bracket 116 and the upper bracket 118, which thereby allowing the forward compartment 100 to be moved about the respective pivot points on the upper and lower brackets.

[0063] The apparatus of the second preferred embodiment of the present invention also includes a lift mechanism that is essentially the same as that shown in FIG. 6. The components of this lift mechanism are also shown in FIG. 8, and they include a load spreader 121 a base ramp 122, a ramp spring 123, a main spring 124 and a wheel and axle assembly 125.

[0064] Finally, the apparatus also includes a further edge extrusion 126 for holding respective edges of the outer panel 103A and inner panel 103B of wall 103.

[0065] When the apparatus shown in FIG. 7 and FIG. 8 is connected to an existing shower cubicle, the apparatus works essentially the same as the apparatus shown in FIGS. 1 to 6. However, it may be necessary to provide the shower cubicle with a false floor 116a in order to obtain a flat or even floor in the shower during use. The false floor 116a may be provided by fitting the false floor into the existing shower cubicle, or by providing the lower bracket 116 with a false floor that extends into the shower cubicle (FIG. 8).

[0066] The benefits of the present invention in providing a larger shower enclosure are demonstrated with reference to FIG. 9 and FIG. 10. In FIG. 9, the shower cubicle is in its closed position. As can be seen, there is only a small amount of room in the shower cubicle when in that closed position. However, when the shower cubicle is opened to its extended position, as shown in FIG. 10, significantly greater room is provided inside the cubicle.

[0067] In other not shown embodiments the earlier mentioned door ramp mechanism may be replaced by some other suitable door lifting device such as a gas strut, mechanical lever or the like.
