Automatic toilet seat cover dispensing and removing apparatus

Abstract

An automatic rolled sheet that can unroll to become toilet seat cover. The dispensing roll is housed within a dispenser housing. The dispenser housing is vertically oriented and located behind the toilet seat. The dispensed sheet is pulled from the dispenser housing onto a toilet seat via a motorized take-up spool within a take-up housing located under the toilet bowl. A sensor detects the presence of a person, and when the person leaves the vicinity of the toilet, the motorized take-up spool winds the used toilet cover sheet onto the take-up spool.

Claims

1. An automatic seat cover dispensing and removing apparatus for a use of covering a toilet seat with an aperture installed on a toilet bowl comprising: a dispenser assembly and a take-up assembly, wherein the dispenser assembly further comprises a plurality of dispensing rolls, each dispensing roll comprising a dispensing spool and a thin sheet toilet seat cover material wound on the dispensing spool, wherein the cover material is comprised of evenly spaced apertures, length of material between adjoining apertures comprising the length of the toilet seat with additional material covering a distance between the toilet seat and the take-up assembly, each aperture of essentially same dimensions as the toilet seat aperture; the take-up assembly comprising a take-up spool for rollingly collecting the sheet of the seat cover material after each use, wherein the take-up spool is rotated by an electric motor; a control assembly comprising an electronic encoder circuit activating the electric motor to move the seat cover sheet material by a distance required for the aperture being rolled off the dispensing roll to be located above the toilet seat aperture, wherein the control assembly being located within the take-up assembly; an occupancy sensor wired to the control assembly, wherein the sensor is located on the outside of the dispensing assembly positioned to sense a presence of a person and sending a signal to the electronic encoder circuit when the person is no longer in range of the toilet to command the motor to wind the dispensing roll sheet onto the take-up spool until a new aperture in the seat cover material sheet is positioned directly over the toilet bowl seat; and the dispenser assembly being placed vertically behind the toilet bowl and the take-up assembly being placed in front of the toilet bowl and below the toilet seat; each dispensing roll comprising a beginning and an end, the beginning and end of each dispensing roll sheet material comprising a magnetic strip fixedly attached across the width of the roll; the dispensing rolls removably housed within an upper dispenser roll housing, wherein the end of a dispensing roll engages the beginning of a full roll to smoothly continue the winding of the seat cover sheet material onto the take-up roll; the take-up roll assembly housed within the take-up roll housing; and the dispensing roll sheet directed down from the dispensing housing and over the toilet bowl seat and then down through a slit in the take-up roll housing and onto the take-up roll spool.

2. A seat cover apparatus of claim 1 further comprising guide rollers within the take-up roll housing to guide the dispenser sheet smoothly onto the take-up roll spool.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(13) Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms to be able to conform to the differing configurations of public toilets. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.

(14) Referring now to FIG. 1 we see a perspective view of the invention 100. A toilet 14, is fitted with a dispenser roll housing 4 and a take-up roll housing 12. A sheet of thin material 8 is unwound from a dispenser roll 18 within the housing 4. The sheet 8 proceeds through a slit 28 to be rolled up on a take-up roll 16 as shown in FIG. 2. An aperture 10 within the sheet 8 is approximately the size and shape of the aperture in the toilet seat 88. A sensor 2 detects the presence of a person. When the person leaves the proximity of the toilet, it sends a signal to a motor 40 and encoder 42 shown in FIG. 10 which rolls in the sheet 8 and stores it within housing 12 for later disposal.

(15) FIG. 2 is a side section view of the invention 100. Dispensing rolls 18, 20, 22 are stacked in a vertical orientation within housing 6. Slots 24 allow spools to slide in and out of the rear portion 6 of the dispensing housing. The vertical orientation of the rolls 18, 20, 22 allows for storage of a relatively large quantity of sheeting material while taking up relatively little space between the back of the user and the front of the toilet assembly 6. Rollers 44, 46 help guide the sheet 8 onto the take-up spool 16.

(16) FIG. 3 is a side perspective view of the invention 100 showing the housing cover 4 removed and one dispensing roll 18 removed from rear housing 26. The receiving slots 24 allow for easy removal and replacement.

(17) FIG. 4 is a perspective view of the invention 100 with the right-side panel of the take-up roll housing removed exposing take-up roll 16 as it rolls up sheet 8.

(18) FIG. 5 is a partial perspective view showing sheet 8 being drawn from dispenser roll 18 as it is supported by spool 19. The sheet 8 passes through two rollers 62, 64 and then slides onto toilet seat 88.

(19) FIG. 6 is a partial perspective view showing the trailing edge 30 of sheet 8 leaving spool 19 and sliding down toward roll 20.

(20) FIG. 7 is a partial perspective view showing the trailing edge of sheet 8 making contact with the leading edge of roll 20. The end of sheet 8 comprises a thin magnetic strip 30 and the beginning of roll 20 comprises a thin magnetic strip 36 so that when the two edges make contact they stick together. In this way, a plurality of rolls 18, 20, 22 can be sequentially joined together to form one long sheet that can be rolled up on take-up spool 16 thereby keeping the width of the dispenser housing 4 to a minimum. Other methods of connection may also be used, such as hook and loop attachment strips or edges comprising rigid U-shaped-inverted U-shaped pairs.

(21) FIG. 8 shows sheet 8 attached to sheet 9 via magnet strips 30, 36 thereby drawing sheet 9 down to be used on toilet seat 88. trailing strips 32 and 34 perform a similar task as each roll 20, 22 is used up.

(22) FIG. 9 is a perspective view of the invention 100 seen from the left side. A cylindrical protrusion 38 to housing 12 accommodates and electric motor 40 and encoder 42 as shown in FIG. 10.

(23) FIG. 10 also clearly shows support rollers 44 and 46. Take-up roll 16 can be removed from housing 12 when all the dispensing rolls 18, 20, 22 are used up.

(24) FIG. 11 shows an alternate embodiment of the invention 200 that is designed to fit on a standard porta-potty unit 214 where the dispensing roll housing 204 would be mounted against the back wall of a porta-potty and the roll receiving housing 228 is mounted on the front wall of the porta-potty 214.

(25) In the above described way, a toilet can have a continuously fresh seating surface for a user thereby reducing the possibility of disease due to touching a soiled toilet seat.

(26) While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
