Abstract
A toilet flushing arrangement designed to encourage keeping the toilet seat and cover in the closed position when the toilet is not in use. The arrangement includes a flexible line having an inner end connected to an internal flush valve and and outer end automatically detachably connectable to a toilet seat cover, when the cover is moved to a vertical open position, so that, when the cover and seat are moved toward a horizontal closed position, tension on the line will lift the flush valve causing the toilet to be flushed.

Description
Background of the Invention
1. Field of the Invention
This invention relates to toilet flushing arrangements, and more particularly to an arrangement for insuring that the seat and cover of a toilet must be moved toward a closed position in order for the toilet to be flushed.
2. Description of the Background Art
A background art search directed to the subject matter of this invention conducted in the U.S. Patent and Trademark Office disclosed the following U.S. Letters Patent:
None of the patents uncovered in the search discloses an arrangement wherein the toilet flush mechanism is operated, only when the toilet seat and cover are moved downwardly toward a closed position, by means of an actuating device substantially all of which is concealed within the toilet water cabinet at all times except during the actual flushing operation.
Summary of the Invention
It is a primary object of the invention to provide an improved toilet flushing arrangement that insures that the toilet seat and cover will normally remain in the closed position when the toilet is not in use.
Another object is the provision of an arrangement for flushing a toilet wherein the toilet flushing mechanism is actuated by the movement of the toilet seat and cover from a vertical open position toward a horizontal closed position.
A more specific object of the invention is to provide an arrangement of the type described wherein a line connected to an internal flush valve is automatically connected to a toilet seat cover, when the cover is moved to a vertical open position, so that when the cover and seat are moved toward a horizontal closed position, tension on the line will lift the flush valve causing the toilet to be flushed.
These and other objects of the invention will be apparent from an examination of the following description and drawings.
Brief Description of the Drawings
FIG. 1 is an isometric view of a toilet having a flushing mechanism actuating device embodying features of the invention;
FIG. 2 is an enlarged view of the structure illustrated in FIG. 1, with portions of the structure broken away;
FIG. 3 is a fragmentary vertical sectional view taken on line 3--3 of FIG. 2;
FIG. 4 is a fragmentary side elevational view, with portions of the structure shown in vertical section, illustrating the toilet seat cover in a vertical open position; and
FIGS. 5 and 6 are views similar to that of FIG. 4, but showing the cover being moved toward a horizontal closed position and in the closed position, respectively.
It will be understood that, for purposes of clarity, certain elements may have been omitted from certain views where they are believed to be illustrated to better advantage in other views.
Description of the Preferred Embodiment
Referring now to the drawings for a better understanding of the invention, in FIG. 1 there is illustrated a conventional toilet, indicated generally at T, comprising a bowl B with a hinged seat S and cover C, and a water cabinet or tank K with a lid L and an internal flush mechanism that includes a flush valve V. As the portion of the flushing mechanism relating to the filling of the tank with water may be conventional, it is not illustrated.
As best seen in FIG. 2, the toilet flushing mechanism is actuated by a device, indicated generally at 10, that embodies features of the invention. The device 10 includes a line guide bracket 12, formed of metal or plastic, that is adapted to be mounted on the toilet tank K under the Lid L.
Bracket 12 includes first, second, third, fourth, fifth, and sixth sections 12a, 12b, 12c, 12d, 12e, and 12f, respectively that are angularly related to each other and arranged to clamp over the upper edge of the tank, with inner and outer portions located within and without the tank, respectively.
As best seen in FIG. 3, the central portion of the bracket 12, comprising sections 12c, 12d, and 12e, is generally U-shaped and adapted to be fitted over an upper edge of the front wall of tank K.
Extending forwardly from the lower end of section 12c is the horizontal section 12b which has the vertical section 12a extending upwardly from the front edge thereof to the lower edge of tank lid L. Sections 12a and 12b comprise the outer portions of bracket 12.
An inner portion comprises section 12f, which extends rearwardly from the lower end of section 12e.
Sections 12a and 12f have holes 12g and 12h, respectively, extending therethrough, and section 12d has a groove 12i in the upper surface thereof. The purpose of holes 12g and 12h and groove 12i is to guide a line 14, as hereinafter described.
A line 14 in the form of a nylon cord or similar flexible material has its outer end attached to a relatively small piece 16 of detachable self-fastening material of the type that will adhere or cohere to a piece of like material upon pressure contact.
In the preferred embodiment of the invention, the detachable self-fastening material employed is Velcro, as shown as elements 16 and 18 in FIG. 1; however, it would be possible to use another material coated with a pressure sensitive adhesive, as shown as elements 16' and 18' in FIG. 6, or a magnetic material, as shown as elements 16" and 18" in FIG. 5, or substance, so long as the two pieces will temporarily self-attach to each other upon the application of pressure thereagainst and will detach from each other when a certain amount of pressure is used to pull them apart.
When the flush valve is closed the material piece 16 is positioned against the outer forwardly facing surface of bracket first section 12a immediately below the toilet tank lid L.
A second piece 18 of like detachable self-fastening material is permanently secured to the upper surface of toilet seat cover C in such a location that when the cover is raised to the vertical open position illustrated in FIG. 4, the two pieces of material will contact and be temporarily attached to each other.
As best seen in FIG. 3 and 6, line 14 is threaded through hole 12g in section 12a, over the top of section 12d in groove 12i, and through hole 12h in section 12f. The inner end of line 14 is connected to a flush valve V at the bottom of the tank K.
A weight 20 is attached to line 14 at a location between the flush valve and bracket sixth section 12f. The primary purpose of the weight is to return the first piece of detachable self-fastening material to its original position against the outer surface of bracket section 12a after the toilet has been flushed, as hereinafter described.
Now to describe the operation of the device. As best seen in FIG. 4, when the toilet seat cover C is in the vertical open position, first and second pieces of detachable self-fastening material 16 and 18, respectively, are in contact with and attached to each other.
When it is desired to flush the toilet, the seat cover C is moved downwardly from the vertical open position of FIG. 4 toward the horizontal closed position of FIG. 6. As this occurs the flush valve is lifted to flush the toilet.
As the seat cover is moved further downwardly, as shown in FIG. 5, the weight 20 moves upwardly until it contacts the underside of bracket section 12f to limit further movement of the line. When further movement of the line is so limited, as the cover and seat are moved to the closed position of FIG. 6, the two pieces of detachable self-fastening material are pulled apart, and the weight places tension on the line to return the first piece of detachable self-fastening material to its original position against the outer surface of bracket first section 12a. At the same time the flush valve is returned to its closed position.
Thus, it will be appreciated that the invention comprises a comparatively simple mechanism that is relatively inexpensive to manufacture, and which can be easily and quickly installed for use on most conventional toilets.
