Claim 4
Dependent Claim
37 words
Device as in claim 1, wherein the measurement signal coming from the electronic formatting unit drives an electronic voice synthesis unit for indicating the weight of the user under the action of a fleeting action control button.
Claim 5
Dependent Claim
28 words
Device as in claim 1, wherein the means for displaying the weight is a printer delivering a ticket bearing the results of the measurement and the corresponding date.
Claim 6
Dependent Claim
149 words
Device for weighing a user of a toilet, comprising a toilet seat (15) fastened by hinges to a bowl (11) and, means for measurement of the user's weight made integrally with said seat (4) and to rest on the upper edge of said bowl (11), including means (8) for displaying the user's weight, wherein each said hinge of the seat is provided with an oblong hole or with sufficient play to avoid disturbing the weight measurement, and said means for measurement of the user's weight includes at least one hydraulic sensor (16,17,18) fastened under said seat (15), and connected to a rigid pipe (19, 20) filled with a pressure transmission liquid, each said sensor (16,17,18) resting on the top edge (29) of the bowl (11) and measuring the pressure prevailing in the pressure transmission liquid therein, and means for displaying said pressure translated into the corresponding weight for display.
