The cabinet encloses a heater with suitable controls for heating the water to a suitable temperature which are visible on a front panel of the cabinet. The device includes a shower stall portion which includes a tray or catch basin at floor level. When folded, the shower stall portion defines a sink drain extending to one side of the sink basin but when it is opened it defines a shower stall with a high back wall for mounting the hand spray and a shower curtain.

COMBINATION SINK AND SHOWER UNIT SUMMARY OF THE INVENTION This invention relates in general to the construction of a combined shower stall and sink and in particular to a new and useful combined sink and shower unit in which the shower portion forms a sink drain when folded.

The invention is particularly directed to the construction of a combined sink and shower unit wherein a sink basin is mounted on a cabinet which contains a water supply and means for heating the water located within the cabinet. Sink cabinets and shower cabinets having integral water supply systems are known, but they are always either constructed as a separate sink cabinet unit or as a separate shower cabinet unit. When such cabinets must be erected, one beside the other, the space which they take up corresponds to the width of the sink cabinet plus the width of the shower cabinet. In addition, in order for the sink to be complete, it must be provided with a drain board, and this requires additional space in constructional materials.

In accordance with the present invention, there is provided a combined sink and shower unit which includes a cabinet mounting the sink basin which provides a housing for the water supply and heating means and which also forms a sidewall of a cabinet forming a sink drain which may be opened up to form a shower stall. One wall of the sink cabinet also forms a wall of the sink drain and shower unit. The front and top walls of the sink drain and shower unit are foldable upwardly and backwardly to define a back wall of a shower stall which also includes a mounting for a hand spray which is connected through a flexible hose into an opening of the sink. The construction of the unit makes it possible to construct a sink, a shower, and sink drain within much less space than the known separate units and which is simpler and less expensive to manufacture. In addition, the shower construction is such that all of the elements may be hidden within a sink drain cabinet formation when the shower is not in use.

Accordingly, it is an object of the invention to provide a combined sink and shower unit.

A further object of the invention is to provide a sink and shower unit which includes a cabinet mounting a sink basin with the usual spout which is adapted to be connected to a water supply contained within the cabinet and a shower stall forming cabinet alongside the sink cabinet which forms a sink drain alongside the sink basin when folded and which includes a front and top wall which are unfoldable upwardly to define a back wall of a shower stall, the back wall including a mounting for a hand spray which is connected through a flexible hose into an opening of the sink.

A further object of the invention is to provide a combination shower and sink unit which is simple in design, rugged in construction and economical to manufacture.

The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, its operating advantages and specific objects attained by its use, reference should be had to the accompanying drawings and descriptive matter in which there are illustrated and described preferred embodiments of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:

FIG. 1 is a diagrammatic front top perspective view of a combined sink and shower unit constructed in accordance with the invention;

FIG. 2 is a view similar to FIG. 1 but showing an embodiment with an enlarged shower tray and indicating the shower cabinet in an opened shower stall forming position; and

FIG. 3 is a view similar to FIG. 2 with a shower curtain in position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings in particular, the invention embodied therein in FIG. 1 comprises a sink cabinet portion generally designated I formed integrally with a combined sink drain and shower stall forming portion generally designated II. Unit I includes a housing 50 which encloses a water supply, heating and pump facilities and connecting piping (not shown) for supplying water to a spout 2 upon actuating either a cold or

hot valve handle

52 and 54, respectively. The spout 2 is disposed at the rear of the sink basin 1 and it is arranged to discharge into the basin. A hand spray or shower head 3 is removably mounted in an opening of the top of the cabinet 50 and is connected through a flexible coupling or hose of a type indicated 3a in FIGS. 2 and 3 to the water supply (not shown) which is contained in the cabinet 50 or which is connected to an external supply.

The equipment (not shown) in the cabinet 50 advantageously includes an electric storage water heater preferably of the two circuit kind and an instrument panel 4 extending across the top front wall of the cabinet 50 comprises a pump switch 5, a temperature cycling control knob 6, a thermostat 7, and two indicating

lamps

8a and 8b of different colors, for example red and green, which serve to indicate the state of operation of the electric water heater and to show whether a high power heater is in operation. For example, a 4 kilowatt heater comprises the high-power heater which operates when the hot water valve 54 is switched on to immediately heat the water as it flows. The low power heater, for example, 0.4 kilowatts, is designed to normally come on automatically when the water temperature in the water heater drops by a certain amount.

In accordance with the feature of the invention the combined sink drain cabinet and shower unit II is formed as a continuation of the unit I and a top wall or sink drain wall 12 thereof forms a sink drain at the same level as the top wall surrounding the basin 1. 'A common rear wall 9 for the unit I also serves as a rear wall for the sink drain cabinet formation indicated in FIG. 1 and it is hinged at its upper end to the top wall 12. The front wall of the sink drain cabinet formation is made up of a partial wall 11 hinged to outer end of the top wall 12 and a front wall 10 of a shower basin or tray 19 which is positioned at ground level.

In accordance with a feature of the invention the complete shower stall may be formed from the unit II by unfolding the front wall '11 and the top wall 12 backwardly and upwardly to a substantially vertical position at which they form a vertically elongated rear wall of a shower stall which is indicated only in the embodiments of FIGS. 2 and 3. The

handles

21 and 22 are provided for facilitating the handling of the parts as well as for the erecting of the rear wall of the shower stall.

In the embodiment indicated in FIGS. 2 and 3, all of the parts have been similarly designated with the exception of the shower tray which has been designated 19' and which is shown as extending forwardly in front of the front wall of the cabinet 50 instead of being flush therewith as in the embodiment of FIG. 1. The shower tray 19' may be made as large as indicated or may be carried as a drawer unit which may be swung out. In some instances it is preferable to form it of interfitting-telescopic parts (not shown).

In FIG. 2 it can be seen how the

walls

12 and 11 are oriented to form a back wall of the shower stall. The wall 11 carries a hook or mounting bracket 56 for mounting the hand spray 3 in a position such that a shower will be directed downwardly on someone standing in the tray 19. The wall 11 also carries a shower curtain frame 16 which may be permanently or detachably secured thereto and which provides a supportfor rings 17 of a shower curtain 58. The shower curtain 58 is provided with a slide fastener closure 18 to facilitate the complete enclosing of the space above the rim of the tray 19'. The frame member 16 may of course advantageously be mounted on a pivot bracket on the wall 11 so that it may be folded inwardly into juxtaposition with the wall when the wall 1 l is in the position forming the front of the sink cabinet as indicated in FIG. 1.

It is possible to design the tray 19' with telescopic sections or as a sliding drawer so that the front thereof may be moved backwardly so that it will be flush with the front of the cabinet 50, as shown in FIG. 1. In the embodiment of FIG. 2, the tray 19' is hinged to the rear wall 9 to permit it to be shifted to a vertical orientation.

While specific embodiments of the invention have been shown anddescribed in detail to illustrate the application of the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
