DETAILED DESCRIPTION OF THE EMBODIMENTS

FIG. 1 illustrates an oblique top view of a preferred embodiment present invention device removable toilet seat cover 10 attached to toilet seat 20. FIG. 2 shows another oblique view of the FIG. 1 present invention device cover 10 and seat 20, but with the cover 10 open to illustrate the force sensor positions, namely, sensors 42, 44, 46 and 48. Both Figures are described together and numbered components refer to either or both Figures in accordance with what is shown.

Cover 10 has a plastic molded body 12 with necessary wiring for connecting the scale parts embedded therein. Processor 18 includes a functional chip that receives force sensor data when a user is being weighed, and processes the data to minimally add the force sensor weights and transmit the results to the display 32. It may include other features such as clock or clock and date calculating, storage of weighing history, a speaker and voice announcement of weight results, etc. The processor 18 is in a housing set into the cover 10 that also has a power supply, such as a battery or other cell, inside that is replaceable. Processor 18 is wired with the embedded wiring to the sensors 42, 44, 46 and 48. Optional on/off or on/sequence readout/off button 34 is connected to processor 18.

Cover 10 is hingedly connected to seat 20 with hinges 26 and 28, and the rotational shaft receivers may be enlarged to permit a small range of floating to eliminate any pull from the hinges 26 and 28 that might otherwise adversely affect the scale reading. Front 14 may be lifted and closed as is any toilet seat cover, and the floating hinge will not affect that functionality.

To use the present invention scale toilet seat cover 10, the cover 10 is in the closed (down) position. When a user sits on the cover 10 and picks up his/her feet, the sensors 42, 44, 46 and 48 press against the seat 20 that presses against a toilet rim (not shown), and these sensors pick up their portion of the weight force, which is transmitted to the processor 18, where processing is rapidly completed and the total accurate weight will be displayed on display 32 (and optionally spoken out to the user, if the optional voice weight announcement feature and components are included with the device).

By using the cover 10 instead of the seat 20 for the scale, a number of advantages are achieved. One is that the display, processor and battery are behind the upended cover during male urination and are thus protected from accidental exposure to corrosive and damaging liquids. Another is that the user need not sit on the seat to be weighed. Another is ease of repair, as the cover is much easier to remove than is a seat. Another advantage is that the cover can be removed for any reason (repair) and not stop the functionality of the toilet. Another advantage is that children not yet large enough for the toilet seat can be held on the cover and weighed. Pets can be weighed without falling in or being frightened by the toilet. Likewise, luggage, small and large can be singularly or together weighed without the need to balance and the risk of falling in if the scale were on the seat instead of the cover. Many other advantages are also achieved with the present invention device, as can now be seen from the description of the present invention set forth herein.

FIGS. 3 and 4 show partial cut side views of the present invention shown in FIGS. 1 and 2, with the cover 10 shown open and detached, and closed and attached, respectively with details of the lock-release mechanism. Identical parts are identically numbered in FIGS. 1, 2, 3 and 4. In FIG. 3, seat cover 10 is detached and male component 30, a part of the lock-release mechanism, is permanently attached to the bottom of cover 10. Hinge 28 includes receiving slot 32 adapted to receive male component 30. When male component 30 is inserted into slot 32, spring loaded pull mechanism 50 automatically locks onto male component 30. To remove the cover 10 for floor scale use, cover 10 needs to be lifted, spring loaded pull mechanism 50 is pulled up and cover 10 is moved slightly back for removal. FIG. 4 shows the present invention device with cover 10 connected to hinge 28 (and left hinge 26, not shown in this figure) in its down (rest) position for dual functionality—to cover the toilet and to present a sitting scale for weighing.

FIG. 5 shows a partial side cut view of another present invention embodiment with the cover removed from the toilet seat and FIG. 6 shows a partial cut top view of the toilet seat shown in FIG. 5 with further details of the lock-release mechanism. Toilet seat cover 60 includes a scale mechanism 62 that functions in a similar manner to those described above. Cover 60 has bracket 64 with a truncated circle orifice 66. Orifice 66 is truncated by virtue of parallel vertical walls that function as a lock-release mechanism component. Referring now to both FIGS. 5 and 6, toilet seat 70 has rear bracket 72 with lock-release bracket 74. Extending to the right of lock-release bracket 74 is axle 78 and key flange 76.

Referring now to FIG. 5, it can be seen that, if cover 60 is rotated to a vertical position, then truncated circle orifice 66 will fit onto key flange 76 and then onto axle 78 for open and close rotation of cover 60 relative to toilet seat 70. Cover 60 may only be removed when positioned vertically and moved to the right. (An identical set of components is shown to the left of rear bracket 72 and functions in harmony with a second truncated circle orifice.)

FIG. 7 shows a block diagram of the critical features of the present invention. Thus, toilet seat 80 and cover with scale 82 are connected at hinge means 84. Hinge means 84 includes lock-release mechanism 86, which is used to remove cover with scale 82 from hinge means 84 and, hence, from toilet seat 80 for use of the scale separate from a toilet and its seat. The lock-release mechanism 86 may embody any of a number of possibilities, including spring-loaded push-to-release locks, spring-loaded pull-to-release locks, slide-to-release locks, position shift-to-release locks, lever latch locks, and others.

FIG. 8 shows a side view of present invention device toilet seat cover 100, that is similar to device 10 of FIG. 1. In this FIG. 8, toilet seat 90 is mounted on toilet 80 (and may be leaned against tank 82 when open). Seat 90 has its normal resting pods, such as pods 92 and 94, and is hinged at the rear end at axle 110 with bracket 96 and bolt 98 affixing it to be rotatably attached to toilet 80. The end of axle 110 has a key flange similar to key flange 76 shown in FIGS. 5 and 6 above, and hence, the cover 100 in this FIG. 8 embodiment is removable and works in the manner and with the same benefit as the FIGS. 5 and 6 embodiment.

Present invention cover 100 has pods such as pods 102 and 104 with force sensors 106 and 108 inside thereof and extending downwardly therefrom, and in contact with the top of seat 90. Cover 100 in rotatable independently of seat 90 and has a tall slot to render it vertically mobile so as to eliminate any hinge pull on a weighing process. Thus, slot 114 is narrow enough to hold onto axle 110 but is tall enough to provide a vertical free floating movement of the cover 100. The processor (inside, not shown) processes the weight information when activated and sends it to be displayed on front 101 display panel 120.

FIG. 9 illustrates schematically a typical wiring and component arrangement wherein force sensors 130 are located on the bottom of a cover and send weight information to a powered processor 140 for processing. The finished weight results (and optional information, such as date and/or time) are sent for presentation to display 150 having one of the arrangements 152.

As shown in FIG. 10, this embodiment of the present invention device includes three force sensors 11, 13 and 15 placed in a triangular symmetrical arrangement on the underside of cover 101. The sensors are integrated into seat cover 101 and are connected via electric wiring, such as wire 17, to an electronic processor unit 21 powered by batteries 19. The device processor unit 21 also formats measurement signals and calculates total added weight delivered by the sensors and transmits it to a digital display means 23 placed on an extension 25 of the front 27 of seat cover 101. Hinging connections 31 and 37 may be similar to those described above.

The total net weight measurement signal can alternatively be transmitted by wire to an outside display (that is, one not embedded in or on or directly attached to the seat cover). This is shown in FIG. 11 wherein toilet seat cover 151 with force sensors 153, 155, and 157 and a processor 159 operate as described above, except that the wire 161 extends to a remotely located display 165. Cell 163 powers the device.

FIG. 12 shows a top view of a wireless present invention device. Here, toilet seat cover 201 has sensors 203, 305, 207 and 209, as shown.

Processor 211 receives weight data from the four force sensors and transmit it wirelessly through transmitter 213 to display 215. Display 215 is wall mounted, but because it has a flat bottom, it could alternatively be set on a horizontal surface such as a sink or countertop. Additionally, display 165 could be programmable to store or store and compare weights, for example, by person and by date of fixed or arbitrarily chosen or programmed periods. Display 165 could be any size, from credit card size to a larger display, and may be any known display technology, including CRT, LCD, plasma, etc.

The next five Figures, that is, FIGS. 13 through 17 all relate to present invention device 250 and are described in conjunction with one another. Identical parts are identically numbered throughout these Figures. Thus, FIG. 13 illustrates an oblique partial view of another embodiment of the present invention, device 250, that shows shift position lock mechanism details. FIG. 14 shows a side cut view of the device 250 shown in FIG. 13 with the seat cover removed. FIG. 15 illustrates a side cut view of the device 250 shown in FIGS. 13 and 14 with the cover at the correct attachment angle. FIG. 16 shows a side view of the present invention device 250 shown in FIGS. 13 through 15, but with the cover attached and in the rest position. FIG. 17 shows an oblique partial cut view of the present invention device toilet seat of FIGS. 13 through 16 above, with the seat cover removed and out of view. Present invention device 250 includes a toilet seat 251, a bowl attachment flange 253 and a toilet seat 255 with a scale mechanism (not shown) that operates in a manner similar to those shown above. Bow attachment flange 253 includes hinge pin bracket 257 and hinge pin 259. Hinge pin 259 has a pin cap 263 shown in FIGS. 13, 15 and 17, but removed in FIGS. 14 and 16 below to illustrate the shape of hinge pin 259 to accommodate lock mechanism receiver 261 located in seat cover 255.

FIG. 13 shows device 250 with seat cover 255 at the correct angle (about 50° from horizontal) for engaging and disengaging lock mechanism receiver 261 with pin 259. FIG. 14 shows the same position of seat cover 255 relative to the other components, but from a side view. As should be now clear from FIG. 14, lock mechanism receiver 261 has a keyway that will fit onto the flats of pin 259 only when the two are aligned.

FIG. 15 shows the same angle of the seat cover 255, but after lock mechanism 261 has be engaged and attached onto the pin. FIG. 16 shows cover 255 in the fully closed position, showing the rotation of the lock mechanism 261 on pin 259 and showing that seat 255, therefore, cannot be removed from pin 259. Thus, a user must go through two steps to remove seat cover 255, namely, rotate seat cover 255 up to an angle wherein the keyway of lock mechanism 261 aligns with the flats of pin 259, and then pull cover 255 away from the pin. This enables the user to place the seat cover with scale on a floor or anywhere else, to be used separately from the toilet and toilet seat.

Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein. Although particular embodiments of the invention have been described in detail herein with reference to the accompanying drawings, it is to be understood that the invention is not limited to those particular embodiments, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims.
