Abstract
ABSTRACT OF THE DISCLOSURE
A hand brush has a handle portion including a reservoir for a cleaning liquid. A liquid outlet channel is formed in the bristle bed of the brush and is closable by a spring loaded closing element, having a projection that extends through the liquid outlet channel into the area of the bristles to a shorter length than the length of the bristles both when the bristles are in their resting position and when normal working pressure is applied to them. It is only when increased pressure is applied to the hand brush that the projection comes into contact with the surface that is to be cleaned, which opens the liquid outlet channel by raising the closing element.

Description
~ 5~09 The present invention relates to a hand brush having a handle including a reservoir for cleaning liquid and a bristle bed that has at least one liquid outlet channel therein.
Hand brushes having a reservoir for cleaning liquid or for a cleaning paste are ~nown. In such hand brushes, the clean-ing liquid runs either automatically out of one or a plurality of liquid outlet channels into the bristles or else it is supplied into the area of the bristles by operation of an outlet valve, this being done either by hand or by expressing the liquid into the area of the bristles through outlet channels. An uncon-trolled outflow of cleaning liquid has been found to be disadvan-tageous because this outflow cannot be monitored and for this reason the cleaning liquid is expended too rapidly. Expression of the cleaning fluid or cleaning paste leads unavoidably and for all practical purposes to an interruption of the cleaning process if the working area is to be supplied with cleaning liquid in a deliberate manner. In addition, the structure of hand-controlled valve systems has been found to be impractical and, in addition, requires relatlvely large expenditures for the system, and this brings about a marked increase in the cost of such hand brushes.
The present invention provides a hand brush of the aforesaid type which permits deliberate control of the manner of which the cleaning fluid is dispensed into the area of the brls-tles, without the need to interrupt the cleaning procedure.
According to the present invention there is provided a hand brush comprising a handle including a reservoir for a clean-ing liquid mounted on a bristle bed provided with a central liq-uid outlet channel, said liquid outlet chan~el being provided with a movable plate-like closing element, which closing element has a peg-like pro~ection that extends through the channel and spaced from the wall thereof into the area of the bristles, the portion of the projection that extends from the liquid outlet channel into the area of the bristles being of a shorter length -::
~ ~ ~ 5~ 09 than the bristles both in their resting position and also when normal working pressure is applied to the brush, said closing element being biassed by a web or plate-like spring which is supported with an edge on an inner step of the handle having a filler opening closeable by means of a screw cap in a wall opposite to the bristle bed.
Thus, according to the present invention, the liquid outlet channel is provided with a movable closing element having a pro~ection which extends into the bristle area of the hand brush, the protruding portion of the pro;ection that protrudes from the liquid outlet channel into the bristle area being of a shorter length than the bristles both in their resting position and when normal operating pressure is applied. This means that using a hand brush of the present invention work can be performed at normal working pressure without any fluid being dispensed from the hand brush reservoir. It is only if an increased amount of pressure ls applied to the hand brush that the bristles in the bristle bed are curved more than is usual, when the closing element pro~ection can come into contact with the area that is to `
be cleaned so that the fluid outlet channel is opened by the closing element being raised, with the result that cleaning liquid can be dispensed. The portion of the closing element pro~ection that extends into the area of the bristles is desirably made o~ a soft, non-scratching material, for example, of shorter bristles or a shorter bundle of bristles, so that the increased pressure on the hand brush can be exerted whilst continuing the cleaning process without any danger than the ob;ect that is to be cleaned will be scratched by the closlng element pro~ection.
In a hand brush of the present invention the walls o~ the handle portion may also be at least partially flexible so that, when greater pressure is exerted on the brlstles, pressure wlIl also be exerted on the handle portion, this tendlng to reduce the .: - - - ~ , ~ ~ ~5~ 09 volume of the reservoir for -the cleaning liquid. This will cause cleaning fluid being squeezed through the raised ' ~ ~

~ ~35~0~3 .
closing element and will make separate venting of the reservoir unnecessary or will simplify positive ventilation through the liquid outlet channel.
A hand brush according to the present invention may be manufactured in a very cost-effective manner from only a few indiviclual components. Its handle portion may advantageously end in a filler opening that is closed by a screw cap. The closing element may most expediently be a simple spring flap or of a spring loaded disk having a peg-like projection that projects spaced from its walls into the cleaning liquid outlet channel. The closing element projection that protrudes into and through the liquid outlet channel to the outside ensures by the movement that it completes when it is activated that there is simultaneously an automatic clearing of the outlet channel and also ensures that any dried cleaning agent residues are dissolved.
The present invention will be further described by way of the accompanying drawings, in which:-Figure 1 is a schematic central longitudinal saction through a round and rotationally symmetrical hand brush according to one embodiment of the present invention; and Figure 2 is an exploded view of the hand brush according to Figure l;
The hand brush is rotationally symmetrical relative to an axis 11 and has a round bristle bed 12 or 12a which on its external side is provided with bundles 13 of bristles and has a continuous central opening 14 that forms a liquid outlet channel. A rotationally symmetrical hollow handle portion 15 adjoins the bristle bed 12, the inner portion of this handle portions 15 forming a reservoir 16 for cleaning liquid, which~

The continuous opening 14 in the bristle bed 12 according to Figures 1 and 2, that forms the liquid outlet channel, can be closed on the inner side of the bristle bed by means of a plate-shaped closing element 20 having a peg-like projection 21 that extends through the continuous opening 14 to the lo outside. The peg-like projection 21 is made o~ a soft and non-scratching material and can be provided with longitudinal grooves. That portion of it that extends into the area of the bristles 13 is significantly shorter than the length of the bristles 13 in the rest position as shown in the Figures.
A disk spring 22 rests against the closing element 20, which in its edge area, rests on an inner step 23 of the handle portion 15. The disk spring 22 may be a simple curved spring with openings (not sho~n) or can be replaced by a spring cross piece supported with both ends on the inner side oP the handle portion 15.
The length of the projection 21 of the closing element 20 or 20a that projects into the area of the bristles 13 is so selected that when normal working pressure is exerted and on the normal bending of the bristles 13 this projection still does not come into contact with the surface that is to be cleaned. It is only when there is increased pressure on the hand brush exerted by the hand to perform work with the brush ~ -that the projection 21 is affected and leads to an opening of the liquid outlet channel 14 by the fact that the closing element 20 or 20a is raised.

The walls of the handle section 15 can be flexible in part, so that when the application pressure applied to the hand brush is increased, pressure can be exerted on the cleaning fluid within the re-servoir 16, which will facilitate the outflow of the cleaning liquid. However, the reservoir 16 can also be vented by means of a conventional flap-type valve (not shown) in the screw cap 19, and this will prevent the cleaning liquid from flowing out when the hand brush 10 is lying at an angle.
