Description

241 4657
BRUSH ASSEMBLY
The present invention relates to a brush assembly for a mechanical rotary sweeper.
There are known a number of mechanical rotary sweepers and brush assemblies for use there with. Such sweepers generally employ two counter rotating brush assemblies arranged to direct swept material to a collecting means lo such as a vacuum.
Brush assemblies for use with such sweepers generally have a disc shaped base plate for attachment to the sweeper with the base plate having brush segments extending there from.
In one known construction the brush assembly comprises a base plate having a plurality of round apertures spaced in concentric bands. Brush filaments are passed through the apertures and then fused together to form discrete brush segments having gaps there between at their free ends.
Such assemblies can be effective but can have the drawback that they do not provide a continuous brush ring for contacting a surface to be brushed. Material can thus work its way between the brush segments and may become trapped thus reducing the effectiveness of the sweeper and causing excessive wear on the brush segments.
GB2369770 provides a brush assembly having fan shaped brush segments mounted to a base plate in a band, however the band is broken by points at which the assembly is to be attached to a sweeper. Thus, there may be gaps between the free ends of adjacent segments and there may be the possibility for material to work its way between brush segments. Additionally, in the described embodiment it is necessary to provide a collar to secure the brush segments in position.
Accordingly, the present invention aims to address at least one disadvantage associated with known brush assemblies whether discussed herein or otherwise.
lo According to a first aspect of the present invention there is provided a brush assembly for a mechanical rotary sweeper, said assembly comprising a base plate for connecting to a mechanical sweeper and a plurality of brush segments having first ends mounted to the base plate and opposed second, free, ends for engaging a surface to be brushed, wherein said first ends of the brush segments are mounted to the base plate in concentric arcs with one or more arcs being radially displaced relative to one or more other arcs.
As used herein the term "arcs" encompasses both curved arcs and arcs which are formed from a number of discrete straight sections which combine to produce a bow shape.
Preferably, the arcs comprise curved arcs.
Suitably, the second ends of the brush segments are arranged to form a substantially continuous ring. The brush assembly may thus allow for a continuous ring of contact between the brush assembly and a surface to be brushed.
Suitably, the brush assembly comprises a plurality of first brush segments having their first ends mounted to the base plate such that they form a first discontinuous ring.
Suitably, the brush assembly comprises a plurality of second brush segments having their first ends mounted to the base plate such that they form a second discontinuous ring.
Suitably, said first and second brush segments are lo arranged such that said first and second discontinuous rings are concentric, with the first discontinuous ring being formed inside of the second discontinuous ring.
Suitably, said first and second brush segments are arranged such that gaps (discontinuities) in said first and second discontinuous rings are offset (ie not aligned) relative to one another.
Suitably, the first brush segments are arranged to span the gaps between the second brush segments. The first brush segments preferably further extend either side of the gaps such that they overlap with the second brush segments.
Preferably, the number of first brush segments and the number of gaps in the second discontinuous ring are equal.
Most preferably, the first brush segments are arranged symmetrically with respect to the gaps in the second discontinuous ring so as to extend by a substantially equal amount either side of each gap in the second ring.
Suitably, the second brush segments are arranged to span the gaps between the first brush segments. The second brush segments preferably further extend either side of the gaps such that they overlap with the first brush segments.
Preferably, the number of second brush segments and the number of gaps in the first discontinuous ring are equal.
Most preferably, the second brush segments are arranged symmetrically with respect to the gaps in the first discontinuous ring so as to extend by a substantially lo equal amount either side of each gap in the first ring.
Suitably, said first and second discontinuous rings of brush segments are arranged such that the second, free, ends of the brush segments form a substantially continuous ring. The brush assembly may thus comprise a continuous brush ring for engaging a surface to be cleaned.
Suitably, each brush segment has a generally arcuate form with each of the first and second ends forming an arc which is substantially coaxial with the base plate.
Suitably, each brush segment extends from the base plate such that its second, free, end forms an arc of greater radius than that formed by its first end.
Suitably, the base plate comprises a first side arranged, in use, to substantially face a surface to be brushed and a second opposed side.
Suitably, the second, free, ends of the first and second brush segments lie closer together than do the first ends of the first and second brush segments.
Suitably, none of the first and second brush segments contact one another at the point from which they extend from the base plate. Suitably, the second ends of parts of each first brush segment contact the second ends of parts of each adjacent second brush segment.
Suitably, the second, free, ends of the first brush segments form arcs having a radius which is the same as, or preferably slightly less than, the radius of arcs lo formed by the second, free, ends of the second brush segments.
Suitably, said radius formed by the free ends of the first brush segments is smaller than said radius formed by the free ends of the second brush segments such that the second free ends of the first and second brush segments each form discontinuous rings and such that said discontinuous rings contact one another to provide a continuous ring having a varying radius.
The brush assembly may be able to provide a two stage sweeping action with the first brush segments brushing up any material on a surface that has not already been brushed up by the second brush segments. The brush assembly may at the same time be such that material is substantially unable to pass the brush segments and avoid being brushed up, or to become caught between segments, as the assembly suitably provides a continuous brush ring for contacting a surface to be swept. The brush assembly may also provide a continuous brush edge without requiring a complicated collar arrangement to mount the brush segments to a base plate. The continuous nature of the brush ring may allow for adjacent segments to provide support to one another such that the brush assembly has a better lifespan than would otherwise be the case.
Suitably, each brush segment comprises a plurality of brush filaments. Suitably, each brush segment comprises a plurality of plastics filaments, for example polypropylene filaments.
Suitably, each brush segment comprises a plurality of lo brush filaments fused together at one end which end forms the first end of the brush segment.
Suitably, the base plate comprises a mounting plate to which the brush segments are attached. Suitably, the mounting plate comprises a disc. Preferably, the mounting plate comprises an annular disc.
Suitably, the mounting plate comprises a first side arranged, in use, to substantially face a surface to be brushed and a second opposed side.
Suitably, the brush segments extend from the first side of the mounting plate. Suitably, the first ends of the brush segments extend into and through the mounting plate.
Suitably, the mounting plate comprises arcuate apertures into which brush segments are mounted. Suitably, said apertures comprise curved arcs.
Suitably, the apertures comprise angled walls orientated such that the apertures have a smaller radius on the second side of the mounting plate than on the first side thereof.
Suitably, the apertures for the first segments have a greater difference between the radii on the first and second side of the base plate than do the apertures for the second segments. The apertures may thus be arranged to cause the first and second brush segments to converge towards their second, free, ends.
Suitably, the brush segments comprise filaments which are lo fused together on the second side of the mounting plate.
Suitably, the filaments are fused such that brush segments can not be withdrawn from the mounting plate by pulling them through the mounting plate from the first side thereof.
Suitably, the brush segments are formed by inserting loose filaments through said apertures and then fusing them together. Suitably the mounting plate comprises a recessed portion, formed on the second side thereof, within which the first ends of the brush segments are arranged to sit. Preferably, the recessed portion is sized to accommodate the fused first ends of the filaments. The brush assembly may comprise brush segments having fused portions which are also fused to adjacent segments.
The mounting plate suitably comprises an inner band, a mid band and an outer band with the inner and mid band being connected by a plurality of first bridges and the mid and outer band being connected by a plurality of second bridges. Suitably, each first segment is held in position between the inner and mid bands and two first bridges and each second segment is held in position between the mid and outer bands and two second bridges. Suitably, the mounting plate comprises a one piece construction. The mounting plate may comprise wood, for example plywood.
Suitably, the base plate further comprises a cover plate which is secured to the second side of the mounting plate.
Suitably, the cover plate abuts the first ends of the brush segments, preferably fused portions thereof, and is arranged such that the brush segments can not be withdrawn lo from the mounting plate by being pushed through from the first side thereof. The cover plate preferably traps the fused ends between it and the mounting plate.
Suitably, the brush assembly further comprises attachment means by which it can be attached to a mechanical sweeper.
Suitably, the attachment means comprise nuts and bolts extending through the base plate.
Suitably, the brush assembly is arranged to be installed onto a mechanical sweeper having a drive plate having keyhole apertures, preferably double ended keyhole apertures, each arranged to receive a nut and bolt.
According to a second aspect of the present invention there is provided a brush apparatus comprising a drive plate for attachment to a mechanical rotary sweeper and a brush assembly for attachment to the drive plate wherein, said assembly comprises a base plate for connecting to the drive plate and a plurality of brush segments having first ends mounted to the base plate and opposed second, free, ends for engaging a surface to be brushed, wherein said first ends of the brush segments are mounted to the base plate in concentric arcs with one or more arcs being radially displaced relative to one or more other arcs.
Suitably, the brush assembly comprises a brush assembly as defined in the first aspect.
Suitably, the drive plate comprises keyhole apertures, preferably double ended keyhole apertures, each arranged to receive a nut and bolt by which the brush assembly may be attached thereto. Once the drive plate is attached to a mechanical sweeper it may thus allow for quick and easy installation, removal and replacement of brush assemblies.
According to a third aspect of the present invention there is provided a mechanical rotary sweeper comprising a brush assembly of the first aspect or a brush apparatus of the second aspect.
The mechanical sweeper may comprise a sweeper of the type known as a "precinct sweeper".
According to a fourth aspect of the present invention there is provided a method of manufacturing a brush assembly according to the first aspect comprising inserting loose filaments into apertures of a mounting plate of a base plate, fusing said filaments together to form brush segments and securing a cover plate of a base plate to the mounting plate to secure the segments in position.
Any of the aspects may comprise features of any of the other aspects in any logical combination.
The present invention will now be illustrated by way of example with reference to the accompanying drawings in which: Figure 1 is a perspective view of a brush assembly; Figure 2 is an underneath perspective view of a brush assembly; Figure 3 is a view of a first side of a mounting plate; Figure 4 is a view of a first side of a mounting plate having brush segments attached; Figure 5 is a view of a second side of a mounting plate; Figure 6 is a view of a second side of a mounting plate having brush segments attached; Figure 7 is a cross section along line A-A of Figure 4; Figure 8 is a further perspective view of a brush assembly; and Figure 9 is a perspective view of a brush apparatus comprising a brush assembly and drive plate.
As illustrated by Figures 1, 2, 3 and 8 a brush assembly 1 comprises a base plate 100, comprising a mounting plate 110 and a cover plate 120, to which are mounted brush segments 200. The brush segments 200 comprise four first brush segments 210 and four second brush segments 220 which are mounted to the mounting plate 110 in concentric arcs.
Both the first and second brush segments are mounted to the mounting plate 110 by their respective first ends 211, 221. The second ends 212, 222 of the respective first and second brush segments 210, 220 are free ends.
The first brush segments 210 are mounted radially inwards of the second brush segments 220. Thus, the first ends 211 of the first segments 210 form a first discontinuous ring and the first ends 221 of the second segments form a second discontinuous ring. The brush segments 210, 220 fan out from the mounting plate 110 such that their second ends 212, 222 converge to form a virtually continuous ring arranged to contact a surface to be brushed.
As illustrated by Figure 4 the first ends 211 of the first brush segments 210 are mounted to the base plate 100 to form arcs having internal radius R11 and the second ends 212 form arcs having internal radius R12, wherein Rll is measured in the plane of the first side 101 of the base plate 100 and R12 is measured parallel to the plane of the first side 101 of the base plate 100.
The first brush segments 210 extend from the base plate such that their second, free, ends 212 form arcs having a radius R12 which is greater than the radius R11 of arcs formed by their first ends 211.
The first ends 221 of the second brush segments 220 are mounted to the base plate 100 to form arcs having internal radius R21 and the second ends 222 form arcs having internal radius R22, wherein R21 is measured in the plane of the first side 101 of the base plate 100 and R22 is measured parallel to the plane of the first side 101 of the base plate 100.
Suitably, the second brush segments 220 extend from the base plate 100 such that their second, free, ends 222 form arcs having a radius R22 which is greater than the radius R21 of arcs formed by their first ends 221.
As best illustrated by Figures 3 and 5 the mounting plate comprises an annular disc having a first side 111 and a second, opposed side 112. The mounting plate 110 has four first arcuate apertures 130 for receiving first brush segments 210 and four second arcuate apertures 140 for receiving second brush segments 220. The apertures 130, form concentric discontinuous rings with the first apertures 130 forming the inner discontinuous ring.
The mounting plate 110 comprises an inner band 151, a mid band 152 and an outer band 153 with the inner and mid band 151, 152 being connected by a plurality of first bridges 154 and the mid and outer band 152, 153 being connected by a plurality of second bridges 155. Each first aperture 130 is defined by the inner and mid bands 151, 152 and two first bridges 154 and each second aperture is defined by the mid and outer bands 152, 153 and two second bridges 155. The inner, mid and outer bands 151, 152, 153 and first and second bridges 154, 155 are integrally formed.
the mounting plate 110 comprises plywood.
The mounting plate further comprises attachment apertures 156 for receiving bolts by which the brush assembly 1 is attached to a mechanical sweeper.
As best illustrated by Figure 7 (which is upside down compared to how the brush assembly would be in use) the first and second apertures 130, 140 have angled side walls 131, 132 and 141, 142 respectively. The side walls are arranged to cause the second, free, ends 212, 222 of the first and second brush segments 210, 220 to form arcs of larger radius than the arcs formed by the first ends 211, 221 thereof. The side walls are also arranged to cause the first and second brush segments 210, 220 to converge towards the free ends 212, 222 thereof.
As illustrated by Figure 5 the second side 112 of the mounting plate 110 comprises a recess 115 surrounding the first and second apertures 130, 140. To manufacture the brush assembly loose brush filaments are inserted through the first and second apertures 120, 140 and then fused together to form the brush segment 200. The recess 115 accommodates the fused portion 201 of the brush segments (illustrated by Figures 6 and 7) and helps retain the segments in position.
To secure the segments 200 in position the cover plate 120, which comprises an annular disc is secured to the mounting plate 110 by being screwed onto the second side 112 thereof. The cover plate 220 further comprises attachment apertures arranged to cooperate with the attachment apertures 156 of the mounting plate 110 and receive bolts to allow the brush assembly to be attached to the drive plate of a mechanical sweeper.
Figure 9 illustrates a brush apparatus 2 comprising a brush assembly 1 and a drive plate 3 arranged to be attached to a mechanical sweeper. The drive plate comprises double ended keyhole apertures 30 arranged to receive nuts and bolts 301, 302 which comprise attachment means 300 of the brush assembly 1. The keyhole apertures are such that the same drive plate may be employed for either clockwise or anticlockwise rotation of a brush lo assembly. To install the brush assembly 1 the nut 301 and bolt 302 are passed through the large part of the keyhole and the brush assembly 1 rotated relative to the drive plate 2 in the direction opposed to the direction in which the brush assembly 1 will be driven so as to cause the bolt 302 to pass into a narrower part of the keyhole 30.
The nut 310 is then tightened. To remove the brush assembly the process is reversed. Thus, once a drive plate 2 is attached to a mechanical sweeper the replacement of a worn out or damaged brush assembly may be a quick and easy process.
As will be readily understood the construction of the brush assembly allows for a one piece mounting plate to support brush segments to define a continuous brush ring which may have a beneficial cleaning action. Accordingly, the present invention provides an effective alternative to known brush assemblies.
