FIG. 10 is a sectional elevation the assembly according to the second embodiment; - Each of embodiments of the invention are directed to an assembly comprising brush adapted to be supported by a housing in order that it can be mounted to a drain of a shower recess or the like installation. Similar devices might also be applied to wash basins and other applications where it is appropriate to have a brush which is accessible to a user of the installation.
- The first embodiment of the invention as shown in FIGS. 1 to 7 comprises a brush assembly which is adapted for installation to the drain in a shower recess, bath/shower combination, wash basin or the like. As shown the
drain brush 11 of the first embodiment comprises ahousing 14, abrush head 16 and acompression ring 18. - The
housing 14 comprises a generallycylindrical skirt 21 having arim 22 in the form of an outwardly directed flange at one end. The external perimeter of therim 22 is constructed in the form of a regular polygon having an even number of sides to enable therim 22 to be engaged by a suitable wrench or socket. The other end of the skirt is dimensioned and adapted to be receivable on the outer end of a drain pipe (not shown) and is formed of a suitable material. Therim 22 is intended to be received in the floor of the shower recess, bath or the like such that its outer axial face is generally flush with the floor and is intended to replace the conventional grate that is usually mounted to the end of the drain pipe in the shower recess or bath. - In addition the inner face of the skirt is formed with an inwardly directed
flange 23 intermediate of its length. The flanges each have a radially directedbase portion 31 and an axially directededge portion 32 extending from outer end of the inner-most edge of thebase portion 32 and in the direction of the one end. Theedge portion 32 with the inner face of the skirt and thebase portion 31 define a recess. The flange is discontinuous in that it is formed with two diametrically opposedgaps 33 and each side of each gap is formed with anaxial flange 37 which extends axially from thebase portion 31 of the flange in opposed relation to the recess and which extends axially to have the same width as theflange 23. Theaxial flanges 37 at each gap are of differing lengths where the longest axial flange is located to the opposite sides of the opposed gaps. - In addition the inner face of the
skirt 21 is formed at its one end with a portion of increased dimension to which defies aseat 24 at its inner end intermediate the one end and theflange 23. - The
brush head 16 of the embodiment is comprised of two components, agrate 41 and acollar 42 where thegrate 41 is receivable in thecollar 42 to be supported thereby and is fixed to the collar. The collar is receivable in thehousing 14. - The
grate 41 is circular and is formed with a set ofgrate members 45 which extend across an opening defined by anannular perimeter portion 43 of the grate. A closedinner zone 46 is defined in the centre of the grate. Theperimeter portion 43 and the inner zone each support a set ofbristles 51 which extend normally from the respective surfaces and where the set of bristles supported from theinner zone 46 are of longer length than the bristles supported by the perimeter portion The bristles take the form of rod-like elements which are formed integrally with thegrate 41. Thegrate 41 is formed of a suitable plastics material which is resilient and provides the bristles with a degree of flexibility so that the bristles are resiliently deformable from their normal orientation with a fair degree of stiffness. The reverse face of the grate is formed around its perimeter with an annular recess which accommodates a set of angularlyequidistant lugs 48. The provision of thegrate 41 within thebrush head 16 provides a series of apertures within the brush head which enables waste-water to enter the drain through the drain brush assembly while providing sufficient support structure for the brush bristles. - The
collar 42 is formed of a relatively rigid plastics material and comprises a tubular member having an external diameter which is substantially equal to the internal diameter of theflange 23 of thehousing 14. The collar is formed at one end with an outwardly extendingsupport flange 62 which has an external diameter substantially equal to the internal diameter of the portion of theskirt 21 having the increased dimension. Theinternal periphery 63 of thesupport flange 62 is complementary to the configuration of the perimeter of the reverse face of the grate having thelugs 48. The inter-engagement of thelugs 48 of the grate with the inner perimeter of thesupport flange 62 serve to positively retain the grate in position in the collar. The exterior of the collar is formed with a pair of diametrically opposedfirst tab members 71 which are located proximate the other end of the collar. The first tab members are intended to cooperate with thegaps 33 in theflange 23 of thehousing 14 to be received through the gaps when the collar is inserted into the housing such that the first tab members are brought into engagement with the flange. - The spacing of the
tab members 71 from the one end of the collar is such that when the brush head is in engagement with the collar the spacing between the axial outer face of thegrate 41 and thefirst tab members 71 is substantially equal to the spacing between the lower face of theflange 23 and the outer axial face of the one end of thehousing 14. Therefore when the brush assembly is received in thehousing 14 the outer axial faces of the housing and the grate are substantially coplanar and the bristles extend upwardly form the grate. In addition theseat 24 limits the degree of inward movement of the brush assembly into the housing by engaging with the innermost axial face of thesupport flange 62. - The
compression ring 18 comprises an annulus of a resiliently compressible material having an inner diameter slightly larger than the outer diameter of thecollar 42, an outer diameter slightly smaller than the inner diameter of thehousing 14. The axial dimension of thecompression ring 18 corresponds substantially to the spacing between the base of the recess defined by theflange 23 and the axial inner face of thesupport flange 62 of the collar when the axial faces of the grate and the housing of the assembled brush assembly are co-planar. The collar is resiliently deformable and may be provided from rubber, neoprene or suitable plastics material. In an adaptation of the embodiment, thecompression ring 18 is replaced by a resilient means such as a helical spring to bias the brush head in an outward position. - In application of the brush assembly, the
housing 14 is first mounted onto a drain pipe such that the rim is positioned to be received in the floor of the shower recess, bath or other appropriate site. Thecompression ring 18 is then applied around the collar between thesupport flange 62 and the first tab members. Thebrush head 16 is then inserted into thehousing 14, with thefirst tab members 71 being aligned with thegaps 33 of theflange 23. As a result the lower axial face of thecompression ring 18 is received in the recess of theflange 23 and will engage thebase portion 31 of theflange 23. With further depression of the brush assembly into the housing, thereby thecompression ring 18 is compressed until thefirst tab members 71 move axially beyond the shortest of theaxial flanges 37. With rotation of the brush assembly within the housing thefirst tab members 71 are moved out of alignment with thegaps 33 and once then the brush assembly is released and allowed to move upwardly under the influence of thecompression ring 18 until the first tab members contact the lower faces of thebase portions 31 of theflange 23, thereby holding thebrush head 16 within thehousing 14. The longer of theribs 37 prevent thebrush head 16 from being rotated within thehousing 14. Thebrush 16 is prevented from being inserted too far into thehousing 14 by the axial inner face of the support flange of the collar step 66 engaging theseat 24 of thehousing 14. Thus, the brush head is provided with a bayonet-like mounting means permitting easy and quick removal and replacement. - In use, the user applies a foot against the bristles and the brush head will move inwardly against the biasing of the
compression member 18. The resilient flexibility of the bristles and the resilient compressibility of the compression ring are balanced to achieve the desired feel. Optionally, the compression ring and bristles can be supplied in a range of grades enabling the user to select a desired “feel” of the brush assembly. As the brush head is removable, it is easily replaceable in the event of damage or wear, or should a user require a different “feel”. - As the apertures provided by the grate in the brush head are interspersed within the area of the brush head provided with bristles, the brush assembly of the first embodiment also acts to prevent certain debris such as hair and dropped items from being washed into the drain and therefore serves a dual function.
- The second embodiment as shown at FIGS. 8 to 10, comprises a brush assembly which can be used with an existing drain fitting 80 and can replace the existing grate of the drain. Such existing drains are formed with an inwardly directed
radial flange 81 at a spacing from the outer end of the drain fitting 83 corresponding to the thickness of the existing grate and the radial flange is formed with a pair of opposed rebates which are intended to receive pawl members provided on the existing grate to enable the existing grate to be positively engaged with the drain fitting but to be capable of removal. - The embodiment comprises a
brush assembly 11 which is of a similar form to the brush assembly of the first embodiment and therefore the same numerals will be used for corresponding component. The brush assembly comprises atubular housing 14 which is intended to be received in the existing drain fitting 80 and which has arim 22 which is to be received by the outer portion of the drain fitting 80 to be supported by theradial flange 81 and which has a pair of pawls which are received through thegaps 83 provided in the radial flange in order that the housing is engaged with the drain fitting 80 in the same manner as the existing grate of the drain fitting. - Generally the
brush assembly 11 of the second embodiment is similar to the brush assembly of the first embodiment. In this regard thebrush head 16 is almost identical to thebrush head 16 of the first embodiment except that all of thebristles 51 have the same length and the pattern obtained from the arrangement of the members of thegrate 41 differs. In addition theflange 23 is formed as a simple flange having a radial extent only. Furthermore thecompressive ring 16 has a castellated configuration at one end to provide for a reduced resistance to the initial relative displacement between the brush head and the housing. - The support sleeve 121 comprises a tubular element having a simple flanged rim 122 at its upper end. It also has a pair of flanges 123 extending circumferentially around the inner surface of the tubular wall of the sleeve intermediate the ends.
- The flanges correspond with
flanges 23 of the first embodiment but are of simpler construction, as they do not have an axial wall portion. As with theflanges 23, the two flanges 123 are opposed to each other and are a little less than semi-circular to provide a pair ofopposed gaps 133 between the corresponding ends of the flanges 123. Thegaps 133 act to cooperate with tags 171 on thebrush assembly 16 while the flanges provide a seat for the compression ring 118. - The sleeve 121 is also provided with a pair of
opposed tags 181 on the external, tubular surface, the tags being positioned near the upper end. The tags are adapted to cooperate withflanges 133 generally constructed on the internal surface of the housing and which are similar in form to the flanges 123 on the inner surface of the tubular sleeve. - The drain brush of the second embodiment functions in a similar manner to that of the first embodiment except that the tubular sleeve is provided as an intermediate element between the housing and the brush assembly. As a result the embodiment can be used in existing installations.
- Modifications and variations such as would be apparent to a skilled addressee are deemed to be within the scope of the present invention. It will be recognized that the pattern of the grate is determined primarily by aesthetics rather than by functional requirements and may be varied without departing from the scope of the invention. In addition, the relative heights of the bristles are selected to satisfy consumer choice and is not an aspect essential to the invention.
- Throughout the specification, unless the context requires otherwise, the word “comprise” or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.
