SANITARY LIFTING DEVICE FOR A TOILET SEAT OR SEAT COVER

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to United States provisional application 60/847,968, filed September 27, 2006 and United States non-provisional application 1 1/861,042 filed September 25, 2007, incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

[0002] This invention relates generally to a toilet, and, more particularly, to a device used to move an element of a toilet without requiring physical contact by the user with the element.

BACKGROUND OF THE INVENTION

[0003] Most toilets in the developed western world include a seat element and a lid element which are pivotably attached to the top of the commode. The seat and/or lid must be lifted or lowered, depending on the requirements of the user. This is typically done by hand. Concern about sanitation when lifting or lowering the seat or lid when using toilets is common, especially when using public facilities. This concern is demonstrated by the number of inventions patented that attempt to address this problem. Those patents can be grouped into three main categories of apparatuses: those that allow the user to directly raise the Hd or seat, those that allow the user to raise or lower the seat or lid using foot actuation, and those that incorporate systems to assist or automate seat and lid operation. While each of these purports to address some aspect of the sanitation problem created by the need to raise and lower toilet elements, none provides the flexibility, portability, and disposability needed to completely address the problem. [0004] Proposed solutions that allow the user to directly raise the seat or lid usually require permanent attachment to the toilet seat, which would then be used directly by the user. But such an apparatus is likely to become as unsanitary as the seat, defeating the main purpose of the apparatus. Examples of such inventions are U.S. Pat. No. 6,721,964 to Marshall, U.S. Pat. No. 6,983,492 to Larson, and U.S. Pat. No. 6,842,916 to Gunn. Each of those lifters allows the user to lift the seat or lid without direct contact, but the lifting element is permanently affixed to the edge of the seat and is likely to be contaminated as well. Temporarily affixed lifters still require direct contact with the most likely soiled parts of the toilet seat or lid, greatly reducing their sanitation utility. For example, U.S. Pat. No. 6,163,894 to Simonds discloses a clip-on type lifter that requires attachment to edge of the seat, as does U.S. Pat. No. 5,619,758 to Burkett. Both of those inventions involve the use of substantial materials making them bulky for the user to transport, and unlikely to be manufactured in a cost effective way that would allow them to be disposable. Moreover, they do not provide significant assistance to people with limited movement or other disabilities.

[0005] U.S Pat. No. 6,305,032 to Jones discloses a direct lifter with a detachable wand that the user grasps on one end by hand. The user then attaches the other end of the wand to an element permanently affixed to a toilet seat or lid, and manipulates the seat or lid by movement of the wand. Due to the permanently affixed element, Jones does not allow for the portability and flexibility required.

[0006] There are also examples of foot actuated inventions that allow raising and lowering of a toilet seat or lid by pressing on a pedal or otherwise actuating a device by foot. Examples include U.S. Pat. No. 7,134,150 to Stewart, U.S. Pat. No. 6,738,990 to Jackson, and U.S. Pat. No. 5,103,506 to Munford, et al. While those inventions accomplish the goal of lifting toilet seats and lids without touching them with the hands, they all require permanent installation of substantial hardware, rendering them nonportable, non-disposable, and expensive to manufacture.

[0007] Several attempts have been made to solve the problem of sanitary toilet seat and lid operation that provide alternatives to direct lifting or lifting via foot actuation. Such apparatuses typically require substantial and permanently installed hardware. A few examples include U.S. Pat. No. 6,567,995 to Holt, U.S. Pat. No. 6,934,974 to Pantos, et al, and U.S. Pat. No. 6,915,532 to Mohammed. While those inventions address at least some of the sanitation issues addressed by the present invention, they do not allow for the portability, versatility, and potential disposability desired. [0008] What is needed in the art is a lifter that can be used with almost any toilet, is simple to use, portable, and inexpensive to manufacture. It is an object of the invention to produce an apparatus for moving elements of a toilet, thereby allowing a user to change the element's position without direct contact with the element and the user's hands. It is also an object of the invention to produce such an apparatus that can be either temporarily or permanently affixed to the seat or lid without any modification of the seat or Hd, and removed when the user is finished for reuse or disposal. The apparatus may be most useful for lifting or lowering a toilet seat or lid, but other uses are contemplated as being part of the present invention.

SUMMARY OF THE INVENTION

[0009] The present invention overcomes the problems left unsolved and provides a simple, inexpensive apparatus that can be used with all types of toilets that have seats or lids. The invention enables the user to raise or lower the lid, seat, or other element of a toilet without contact with the element, thereby reducing the likelihood that the user will come into contact with germs or contaminants. Due to its few parts and simple design, the present invention can be manufactured inexpensively and carried as a lightweight, portable apparatus to lift toilet elements, or as a disposable lifter that can be discarded after use. It can also be permanently affixed, providing a permanent solution to this toilet sanitation problem.

[0010] The present invention includes an apparatus for moving elements of a toilet without direct contact by the user's hands. The apparatus contains a member with two ends which is attached to a toilet element at the first end with an attachment means, and optionally a handle attached to the second end. The apparatus is operated by pulling up or down on the second end of the member, thereby moving the toilet element. The member may be attached temporarily using several attachment means, including, but not limited to, a suction cup for attaching to any smooth surface of the toilet, an attachment element with an adhesive portion for adhering to a toilet element, or a magnet or several magnets for attaching to a toilet element that is constructed of iron, metal with iron content, or is otherwise magnetic. The member may be attached more permanently using an adhesive in combination with an attachment means such as a suction cup, or physically attached with a screw or similar permanent attaching means. The member may be constructed of any suitable material that allows the invention to function properly, including, but not limited to, rope, string, chain, cord, cable, tether, or wire. The optional handle may be constructed of any suitable material capable of carrying out the functionality described herein, including, but not limited to, plastic, wood, metal, or any of the materials that could be used for the member.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0023] FIGS. 1-11 illustrate various embodiments of an apparatus for use on a toilet 150, which allow a user to move an element of the toilet such as Hd 151 or seat 152 without having to touch the element with his or her hands.

[0024] FIG. 1 illustrates one embodiment of an apparatus 100 in its typical operating environment, attached to a toilet 150. Toilet 150 is composed of common elements found in a modern toilet, including a commode 153, a tank 154, a seat 152, and a lid 151. Seat 152 and lid 151 are commonly connected to toilet commode 153 with at least one hinge, allowing seat 152 or lid 151 to be placed in a "down" position where they are horizontally situated and resting on the commode, or an "up" position where they are vertically situated and resting against tank 154. Having both lid 151 and seat 152 in the "up" position allows full access to the interior of commode 153. Lid 151 alone may be in the "up" position with seat 152 down, which allows access to the interior of commode 153 through an opening in seat 152. Lid 151 must be in the "up" position for seat 152 to be in the "up" position. Toilet 150 may contain additional elements or fewer elements than illustrated here, or elements of varying styles, shapes, and dimensions than shown in FIG. 1 without affecting the functionality of the present invention.

[0025] In the embodiment illustrated by FIG. 1, and in further detail in FIG. 2, apparatus 100 has a member 101 with a suction cup 103 on the first end for attaching the first end to an attachment point on toilet 150, such as lid 151. Member 101 is preferably constructed of an elongated, flexible material such as rope, string, or wire, but could be constructed of any material capable of carrying out the functionality described herein. Suction cup 103 is preferably of a small enough size to allow attachment to any side or edge of a toilet seat 152 or a toilet lid 151, but may be of any size or shape capable of carrying out the functionality described herein. In this embodiment, suction cup 103 allows apparatus 100 to be affixed to toilet 150 for use and easily removed following use. This temporary affixation of apparatus 100 permits the reuse and portability of apparatus 100, and also prevents the need to permanently affix apparatus 100 to toilet 150. However, if permanent affixation is desired, a glue or adhesive may be used to attach suction cup 103 to toilet 150.

[0026] The embodiment shown in FIG. 1 and FIG. 2 has a laterally attached tubular handle 102 on the second end. Tubular handle 102 is preferably constructed of inexpensive, lightweight material to permit portability or disposability of the apparatus, yet strong enough to lift the weight of toilet seat 152 or toilet lid 151. Handle 102 may be constructed of any material and be-of any size or shape capable of carrying out the functionality described herein. While not shown in the drawings, the apparatus can fully function without handle 102.

[0027] As shown in FIG. 1, apparatus 100 is attached to toilet lid 151 with a suction cup 103. In this application, a user operates apparatus 100 by grasping handle 102 attached to the second end of apparatus 100 and pulling up, which will lift toilet Hd 151 into its upright position. By using apparatus 100 in this way, the user can lift lid 151 of the toilet without touching it directly with his or her hands. FIG. 3 further details this application of apparatus 100, providing a top view of the configuration. FIG 3. illustrates suction cup 103 attached to the middle section of lid 151, but suction cup 103 of apparatus 100 may be affixed to any surface of toilet lid 151 that will allow it to attach properly.

[0028] FIG. 4 shows how apparatus 100 can be used to lift a toilet seat 152. Apparatus 100 is affixed to toilet seat 152 with suction cup 103. Similar to its application to toilet lid 151 as shown in FIG. 1 and FIG. 3, suction cup 103 may be affixed to any area of toilet seat 152 that will allow it to attach properly. In this application, the user will grasp handle 102 and pull upwards, thereby raising toilet seat 152 to its "up" position. This allows the user to raise seat 152 without direct hand contact, preventing unwanted contact with contaminants. The apparatus may be used in a similar fashion to raise toilet lid 151. In the configuration illustrated in FIG. 4, apparatus 100 may also be used to lower toilet seat 152 or toilet lid 151.

[0029] FIG. 5 illustrates how apparatus 100 may be used to lower a toilet seat 152. In this application, with lid 151 and seat 152 both in the "up" position, suction cup 103 is affixed to the underside of toilet seat 152. Suction cup 103 may be attached to any surface of seat 152 that can support its affixation. The user will grasp apparatus 100 by handle 102, and pull down, lowering the seat to its "down" position. This allows the user to lower the seat without touching it. The apparatus may be used in a similar fashion to lower toilet lid 151. In the configuration illustrated in FIG. 5, apparatus 100 may also be used to raise toilet seat 152 or toilet lid 151.

[0030] FIG. 6 illustrates a second embodiment of the present invention, with an apparatus 600 for use on a toilet having a member 601 with an adhesive element 603 for attaching the first end to an attachment point on the toilet 150. Element 603 may be constructed of a magnetic material with a size that is sufficient to produce the magnetic adhesion required to lift or lower a typical toilet seat or lid, yet small and inexpensive enough to be easily portable or disposable. Alternatively, element 603 may be constructed of other materials capable of producing the necessary adhesion to adhere the embodiment to a toilet element. For example, element 603 may be composed of a plastic element coated with an adhesive substance on one side which, when pressed against a toilet seat or lid, adheres to the seat or lid. However, element 603 may be of any size, shape or material capable of carrying out the adhesive functionality described herein. Where element 603 is a magnet, it is preferably configured to be magnetically coupled to a magnetic portion of toilet 150, or alternatively to a magnetic attachment affixed to toilet 150. Likewise, if element 603 is non-magnetically adhesive, it is preferably constructed to adhere to elements of the toilet which a user may wish to actuate, such as the lid or seat. In this embodiment apparatus 600 also has a ring-shaped handle 602 attached to the second end of member 601. Ring handle 602 is preferably small and light enough to be easily portable and inexpensive enough to be disposable, yet strong enough to lift the weight of toilet seat 152 or toilet lid 151.
