Foldable bottom wiper

Abstract

A foldable bottom wiper. The foldable bottom wiper includes a wiper head having a paper contact surface extending from a base, and a handle extending from the head. The paper contact surface has a recess into which toilet paper can be tucked. In use, toilet paper can be placed over the contact surface and secured thereto by tucking part of the paper into the recess whereby the papers are secured to the head while paper on the head is wiped over part of a bottom to be cleaned with the contact surface of the head facing generally upwards, and the soiled paper being removed by facing the head generally downwards and allowing the papers to fall off under gravity.

DETAILED DESCRIPTION OF THE INVENTION

(6) Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the foldable bottom wiper. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for wiping a user's bottom. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

(7) Referring specifically to FIGS. 1A and 1B, there is shown perspective views of the foldable bottom wiper in the folded position and unfolded position, respectively. Wiper 1 has a wiper head 10 having a curved paper contact surface 11 extending from a base 12. The paper contact surface 11 has a U-shaped recess 13 with an opening 13A into which toilet paper can be tucked. The contact surface 11 is formed of a friction material. The material may be a thermoplastic elastomer which is over-moulded on a plastics base. The contact surface 11 has an upper face 11A with side walls 11B, 11C between the upper face and the base, and the recess 13 opening 13A is formed in the upper face. The recess 13 includes a pair of inwardly directed opposing projections 13B, 13C.

(8) A handle 20 extends from the head 10. Handle 20 is formed from two first and second sub-sections 30, 40 which fold from a storage position around the head (see FIGS. 1A and 2A) with head 10 adjacent subsection 40, to an in-use handle position (see FIGS. 1B and 2B) with head 10 folded away from subsection 40. The first sub-section 30 is hinged to the second sub-section 40 with hinge 50, and the second sub-section 40 is hinged to the head 10 with hinge 60.

(9) In the in-use handle position the first sub-section 30 extends from the second sub-section at an angle (around 140 to 160 degrees, e.g. 150 degrees) on one side of the second sub-section 40, and the head 10 in use extends at an angle (around 110 to 130 degrees. 120 degrees) to an opposing side of the second sub-section 40, whereby the wipe tends towards a Z-shape. Releasable friction catches are provided to hold the wiper in the unfolded in use position and folded position and form part of hinges 50 and 60.

(10) Referring to FIGS. 1A-2B, the hinge 50 has a hinge pin 51 forming the hinge axis which passes through the adjacent ends of first and second sub-sections 30, 40. The hinge 50 includes a static cylindrical section 52 fixed to the end 40A of the second subsection 40 of the wiper. The circumference of section 52 forms a cam surface 53 with two opposing steps 54A, 54B thereon. An end edge 30A of first sub-section 30 forms a cam follower on the cam surface 53 as it rotates away in one first direction from the second sub-section 40 opening the wiper. The edge 30A passes over the steps 54A, 54B around the cylindrical section circumference to the position shown in FIG. 2B. In this position the step 54B forms a friction stop to the edge to help prevent rotation of the first sub-section 30 in the other second direction towards second sub-section 40 closing the wiper. The wiper can be closed by rotating the first sub-section 30 towards second sub-section 40 with extra force to cause the edge 30A to pass over step 54B, and then ride over step 54A as shown in FIG. 2A where step 54A forms a friction stop to the edge 30A to help prevent rotation of the first sub-section 30 back in the first direction away from second sub-section 40 re-opening the wiper.

(11) Preferably the cylindrical section is formed of a pair of concentric cylinders 55A, 55B connected together by at least one flexible spoke 56 with the outer cylinder 55A forming the cam surface, the outer cylinder being displaceable relative to the inner cylinder to allow the cam follower to ride over the steps 54A, 54B.

(12) Hinge 60 works in an identical way to hinge 50, with a hinge pin 61 forming the hinge axis which passes through the adjacent ends of head 10 and second sub-section 40. The hinge 60 includes a static cylindrical section 62 fixed to the end 40B of the second subsection 40 of the wiper. The circumference of section 62 forms a cam surface 63 with two opposing steps 64A, 64B thereon. An end edge 10A of head 10 forms a cam follower on the cam surface 63 as it rotates away in one first direction from the second sub-section 40 opening the wiper. The edge 10A passes over the steps 64A, 64B around the cylindrical section circumference to the position shown in FIG. 2B. In this position the step 64B forms a friction stop to the edge 10A to help prevent rotation of the head 10 in the other second direction towards second sub-section 40 closing the wiper. The wiper can be closed by rotating the head 10 towards second sub-section 40 with extra force to cause the edge 10A to pass over step 64B, and then ride over step 64A as shown in FIG. 2A where step 64A forms a friction stop to the edge 10A to help prevent rotation of the head 10 back in the first direction away from second sub-section 40 re-opening the wiper.

(13) Again the cylindrical section may form of a pair of concentric cylinders 65A, 65B connected together by at least one flexible spoke 66 with the outer cylinder 65A forming the cam surface, the outer cylinder being displaceable relative to the inner cylinder to allow the cam follower to ride over the steps 64A, 64B. The free end 31 of the first sub-section 30 is shaped so that is provides a thumb rest.

(14) In use, with the wiper in the unfolded position, toilet paper is placed over the contact surface and secured thereto by tucking part of the paper into the recess whereby the papers are secured to the head whilst paper on the head is wiped over part of a bottom to be cleaned with the contact surface of the head facing generally upwards. The soiled paper can be removed by facing the head generally downwards and allowing the papers to fall off under gravity, e.g. into a toilet pan.

(15) The wiper of the invention is designed to fit in a pocket when folded. Air holes may be provided body of the second sub-section 40 to allow the contact surface to be exposed to ambient air.

(16) It is therefore submitted that the instant invention has been shown and described in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

(17) Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
