SUMMARY OF THE INVENTION
It is an object of the invention to provide a novelty shower unit to make showering more fun.
According to the invention there is provided a sprinkler shower unit incorporating a game of chance machine, the chance machine comprising a plurality of cylinders arranged side by side and rotatable about a common axis, each cylinder having a number of visual displays displaced around its peripheral surface, including a window in an exposed surface of the shower unit through which a selected portions of the periphery of each cylinder can be viewed, in which the chance machine includes a mechanical energy storage means that is charged by normal flow of water through the shower unit during use, and a mechanical drive mechanism arranged to apply stored energy to rotate the cylinders and so that they come to rest to provide different combinations of the visual displays located in the window from time to time during use of the shower.
The sprinkler shower unit may include means to release stored energy to the cylinders whenever flow of water through the shower unit ceases.
The stored energy means preferably comprises a coiled spring that is wound up by flow of water through the shower unit.
The sprinkler shower unit may include a water impeller wheel and a biassed dog clutch connected between the impeller wheel and the coil spring, including a pressure plate arranged to engage the clutch when water pressure in the shower unit is increased by flow of water therethrough.
The sprinkler shower unit may include an axially slidable drive shaft on the common axis to support the cylinders, including a separate clutch for connecting each cylinder to the drive shaft arranged to transfer stored energy of the coil spring to rotate the cylinders, including biassing means to slide the shaft into a position such that the clutches are normally disengaged, the arrangement being such as to allow the stored energy to rotate the cylinders via the separate clutches for limited periods of time whenever the spring unwinds.
