Abstract
A TOILET BRUSH
ABSTRACT of the DISCLOSURE
A toilet brush, of which at least the tufts located nearest the connection of the head molding and the handle are canted back toward the handle, set at an acute angle in relation to the longitudinal axis of the brush, and of length such that the tips project back beyond the connection between head and handle, revolution of these angled tufts about the brush axis will generate a number of essentially frustoconical surfaces by which the head-handle connection is encompassed entirely, and the handle encompassed in part.

Description
2~ 37 BACKGROUND of the INVENTION
The invention relates to a cleaning implement of brush type embodiment, and in particular, to a .
toilet brush.
Implements of the type in question have been on 05 general sale for some considerable time; a typical .
brush will consist in a handle, extending along a ~-main longitudinal axis and connected by one end to a block, or molding, by means of which to support a plurality of cleaning elements (generally tufts of bristles) arranged variously and in such a way as to create a head suitable for cleaning different objects a.nd surfaces.
The brushes to which the present invention relates in particular, i.e. those utilized for cleaning toilet bowls, are embodied with flat and round heads alike, exhibiting a variety of shapes and sizes to suit varying requirements. Such brushes are certainly adequate when cleaning the flat or gently contoured surfaces of the bowl casting, but .-prove less effective in tackling the internal or more tortuous profiles, especially the recessed underside of the rim; in effect, more than one reason exists for ensuring that these less readily 2Q~ 3~
accessible surfaces are thoroughly cleansed, as in addition to the normal use for which the bowl is ~ ~;
intended, one has the formation of a significant ~;
quantity of lime deposits, given that the rim is 05 generally cast with holes through which to channel ~ ;
the flush water.
Several specific expedients have emerged, aimed at successful cleaning of the recessed surfaces of a toilet bowl as described above, of which a first, for example, consists in providing a conventional ~ `~
brush with additional tufts seated in the part of the head nearest the handle and set in the opposite ~`
direction to that of the main body of bristles.
A second expedient, embodying a wholly new concept, consists in fashioning a brush with a head molding of pear-drop shape and a plurality of tufts, set in and twisted around the molding and exhibiting a given profile.
A third expedient consists in the use of chemical --~
substances to dissolve the lime, though solutions of this nature lie outside the scope of the present invention and the appended claims.
At all events, none of the expedients outlined is able to provide an ideal solution to the difficulty in question; indeed each is beset by at least one `,'- ' ,' ~
5~
drawback such as renders the cleaning of recessed toilet bowl surfaces either incomplete or hard to accomplish. In the first expedient mentioned, an insufficiently generous surface is afforded by the 05 additional bristles, resulting in only a partial cleansing action. The second type of brush i~ not especially convenient, being suitable for cleaning recessed surfaces, though un~uitable for the bowl in its entirety; furthermore, the brush is not easy to handle on the part of the user, by reason of the fact that the arm manipulating the brush needs to be extended into the bowl. The third expedient can become di~advantageous due to the fact that with ;
continued use of chemical agents, water flushed from the bowl will become a source of pollution.
Accordingly, the object of the present invention is to overcome the drawbacks described above.
SUMMARY of the INVENTION
The stated object is achieved with a toilet brush according to the invention, which is of the type consisting in a block or head molding, supporting a plurality of tufted bristles and connected to a handle. In the brush disclosed, at least the tufts , . . ~ , . . .

BRIEF DESCRIPTION of the DRAWINGS
The invention will now be described in detail, by way of example, with the aid of the accompanying drawings, in which: :
-fig 1 is a side elevation of the brush disclosed;
-fig 2 is a side elevation of the brush of fig 1, illustrated with certain parts omitted better to reveal others; : ~
-fig 3 is the sectional illustration of a toilet - :~;bowl, showing the brush in operation; :~.-figs 4 and 5 are further side elevations showing `~
two alternative embodiments of the brush. ~.. .
DESCRIPTION of the PREFERRED EMBODIMENTS
With reference first to fig 1, a brush according to .` ~
the invention consists substantially in a handle 1, - `
generally of elongated appearance, provided with a '",.' '.'"~"
XQ~ 3~
grip 4 at one end and connected by its remaining end to a head of which the block, or molding, is denoted 3.
The head molding 3 affords a plurality of holes 5 05 accommodating a plurality of cleaning elements, each one of which consisting substantially in a set of tufts 2, inserted in such a manner as to project from points distributed over the entire available surEace area of the head. The head molding 3 is essentially cylindrical in embodiment, disposed ~ :
coaxial with the handle 1 though exhibiting a wider radius, and crowned at its projecting end.
According to the invention, the tufts 2 occupying a part of the head molding denoted 3a, which lies adjacent to the connection 6 of the head molding 3 .
with the handle 1, are canted back in the direction of the handle at an acute angle (see fig 2, where a denotes the angle of certain of the tufts 2).
These angled tufts 2 are of length such that the projecting ends extend back beyond the part 3a of the head molding which they occupy, and moreover, such that their revolution about the longitudinal axis x of the brush will describe a plurality of substantially frustoconical surfaces 10, centered on the axis x.
. !,; : . . .
.'., . ' ,, : ' ' , ~ ' . ' . ' . ' 543~ ~
More exactly, the rearwardly angled tufts 2 combine to generate a series of frustoconical surfaces 10 by which the connection 6 between the head molding and the handle 1 is encompassed entirely, and the 05 handle itself encompassed in part (as discernible from fig 2~.
The projecting ends of the tufts 2 distributed over -:~`.
the entire surface area of the head molding 3 combine to describe a surface 7 substantially of domed shape, which represents the outer profile of the brush head. In particular, the greater base of the innermost frustoconical surface 10, nearest the :~
handle, coincides with the skirt of the dome 7. `:
It will be seen from figs 2 and 3 that the length of the tufts 2 is markedly varied, and increases progressively from the tip of the brush back to the h`
connection 6 of the head with the handle 1.
With a brush embodied according to the invention, - -the operation of cleaning any recessed parts of a toilet bowl (fig 3) is considerably facilitated; ` `
gripping the handle 1 and offering the brush down . ``
into the bowl, in fact, it becomes possible to ~ ~ .
direct certain of the acutely angled tufts 2 up :
into the recess, while the shorter tufts 2 clean ;:
the surface adjacent to the rim recess. :`

The two sections 3a and 3b of the head molding are ~;.
rigidly associated with the handle 1, for example .
screwed thereonto, and will be tightened together . . .
to the point of making contact and forming a single head as shown in fig 2.
Fig 5 shows a further embod:iment of the invention, which differs from those described thus ~ar in that only certain of the tufts 2 carried by the part 3a of the head nearest to its connection 6 with the handle 1 are of length such that their projecting ends extend back beyond the connection 6.
