Description

<p>I</p>

<p>Improved Broom The present invention concerns an improved sweeping device for sweeping particulate materials. In particular, the present invention concerns a novel combination and/or interconnection of known brush elements for providing improved sweeping, such as when used by a single person, such as a child and particularly when in the form of a brush and most particularly when in the form of a broom usable for sweeping a floor.</p>

<p>A brush, particularly in the form of a broom is a well established means for assisting in the manual movement of particulate materials on a surface, such as to facilitate collection of particulate materials off that surface. A hand brush typically comprises a head in which a plurality of bristles are retained to form a brush head and also a handle connected to the head for facilitating manual manipulation of the brush. A broom is as brush specifically adapted for manually brushing a floor or other surface on which a person normally stands. A wide variety of brush handle sizes and shapes are known. A broom comprises an elongate handle suitable for enabling a person to conveniently hold and manipulate the broom with its brush head in contact with a floor, so as to facilitate manual brushing whilst in a standing posture.</p>

<p>A wide variety of bristles are used in brushes and brooms. The type of bristles can vary from fine filamentous fibres to thick wires depending upon the intended use of the brush.</p>

<p>Brooms, particularly those for household use typically provided in two forms, a fme, less than 0.5mm diameter, bristle for brushing indoors; a coarse, 0.5 to 1mm, bristle for outdoors; and a very coarse, greater than 1mm diameter, bristle for brushing coarse materials, such a may contain gravel and the like outdoors. Brush heads also come in an equally wide range of sizes.</p>

<p>The vast array of brushes used in a household and other situations, such as in institutions, hotels and the like, gives rise to complexity, inconvenience and inefficiency as various brush types need to be kept, maintained, chosen, used and replaced; even in a cleaning operation for a single area. For example, brushing an outdoor area may require use of a very coarse brush initially, followed by use of a finer brush. I, Samuel Thomas Houghton, observed that my daddy was wasting time swapping between brushes when brushing up and also not doing a very good job of it. I have therefore devised a new broom to obviate or mitigate some or all of the disadvantages of known sweeping devices as stated herein.</p>

<p>The present invention, in its various aspects, is as set out in the appended claims.</p>

<p>The present invention provides sweeping device for sweeping a surface, the device comprising a combination of two brushes connected by a resilient connector; the first brush comprises a brush head, a plurality of bristles affixed to the brush head and a handle extending from the brush head; the second brush comprises a brush head, a plurality of bristles affixed to the brush head and a handle extending from the brush head, wherein the resilient connector serves to retain said combination of brushes in resiliently moveable relation to one another in use. The resilient connector is preferably used to connect the handle portions of the first and second brushes. The sweeping device preferably substantially comprises said two brushes, that is to say that the only mechanical components of the device which contribute to sweeping are those described.</p>

<p>The invention is therefore simple and economic to manufacture, repair and maintain. The sweeping device is preferably a manually operated sweeping device.</p>

<p>In the present invention the sweeping device is very preferably configurable, in at least one method of use, so that the first brush is configured, in use, to precede the second brush as both brushes pass over and in contact with a surface to be swept so both brushes pass along a substantially similar path. All be it that, unless used in a circular path, the first and second paths of the first and second brushes never completely overlap over their whole range of travel, the paths being parallel, or preferably coincident. Preferably brushes not capable of, or reasonably useable for, or intended for use in an independent manual sweeping action are not considered to be within the scope of the present invention. Brushes for manual use are advantageous over motorised or propelled brushes as they have a lower environmental impact.</p>

<p>A preferred brush handle of the present invention is a handle having a length more than five times the diameter (or equivalent dimension. e.g. width) of the handle, more preferably having a length more than thirty times the diameter. Brush handles of the present invention are preferably straight, more preferably linear. Brush handles of the present invention are preferably cylindrical.</p>

<p>As the first and second brushes are, in the present invention, not separate entities but components of the sweeping device the brushes may be considered as brush components (or component brushes), in the sense of a sweeping device comprising brushes rather than components (e.g. bristles) of a brush. However, as the two brushes of the invention may exhibit differential wear in use, then an advantage of the present invention is the ability to replace brush components by reversibly disconnecting the resilient connector, such as by resiliently deforming the connector to allow removal of a brush from the sweeping device so as to allow its replacement with a suitable replacement brush, so as to reform and hence conveniently repair the device of the invention.</p>

<p>In addition, or alternatively, the invention permits a user to manually manipulate one or other of the brushes in contact with a surface to be cleaned during a cleaning operation such that it is not necessary to swap between cleaning devices, such as between a brush head that has been made foul (such as full of fluff etc) and a fresh brush head. This makes for a more efficient use of time and an improved sweeping action.</p>

<p>The resilient connector permits, in use, during a brushing operation the two brushes to be manipulated such a manner that the bristles of both brushes may contact the surface in a configuration such that particles not retained by one brush may be retained by the other brush (i.e. first and second brushes). A single brushing operation is therefore possible using the present invention whereby particles being brushed, such as for brushing up into a shovel, have a greater chance of retention than by a single brush alone, even when that single brush may pass twice over the same given surface. Further the chance of retention (brushing being a statistical operation) is greater when the first and second brushes differ in their bristles (the term bristles being used in its functional sense).</p>

<p>Further when sweeping up particulate materials the potential for a row of bristles in a brush to retain material in part depends upon the degree of movement of the particles.</p>

<p>Hence, using two separate brushes enables disturbed particulate material to settle before encountering the second brush, where it may be more easily captured. This provides a benefit overt an equivalent single brush of greater depth, where particles cannot come to rest between rows of bristles and a greater number of rows of bristles would be needed to obtain the same level of retention of particulate materials. The first and second brushes of the invention are therefore preferably separated, such as when in use, by one brush depth, preferably two or more brush depths, most preferably by five or more brush depths.</p>

<p>The resilient connector is chosen so that in normal manual use of the device for sweeping particles the parts of the brushes, such as the handles, on which the resilient connector is held in pace (such as by its elasticity or by direct attachment) are held in substantially similar proximity, all be it that their relative orientations may change.</p>

<p>The resilient connector may in some embodiments comprise a single rubber collar. The resilient connector may in other embodiments be wrapped in a figure of 8 (central overlap) configuration around the handles (14, 24) or be in a single moulded figure of 8 (central join of two loops), the handles (14, 24) each passing respectively through an apertures in said figure of 8. The resilient connector may comprise a spring, such as a leaf spring or a coil spring. The present invention also encompasses the use of a resilient connector in combination with brushes to provide a sweeping device of the present invention. The resilient connector preferably comprises a single elastomeric band, such as a band comprising rubber. The resilient connector or band may preferably be wrapped several times around each brush component.</p>

<p>The resilient connector may connect the brush components at any convenient location such that the advantages of the present invention may be realised. However, the resilient connector preferably serves to connect the brushes at their handles. Connection of the handles is preferably in a central region of the handles intermediate a brush head end and a remote terminal end of said handles. The resilient connector is preferably at a central portion of the second brush handle and an upper portion of the first brush handle, this facilitates manual handling. The first brush is preferably in communication with the resilient connector at a lower part (i.e. towards the brush head end) than with the second brush.</p>

<p>The bristles of the first and second brushes may be the same or different. In a preferred embodiment the bristles are different, the first brush having bristles adapted to sweep up coarse particulate material (such as grit) and the second brush having bristles adapted to sweep up fine particulate material (such as dust). However, it will be appreciated that the terms coarse and fme will depend upon the intended use of the brushes, for example, sweeping up in outside may can best be accommodated by bristles adapted to sweep grit and bristles adapted to sweep leaves. However, for indoor use, bristles adapted to sweep litter and bristles adapted to sweep dust will be preferred. The various choices are all within the scope of the present invention. The first brush may preferably be configured as a leading brush (such as the first to encounter particles in any given sweep) and the second brush may be configured as a trailing brush (such as to travel behind the first brush). Coarse bristles may be considered as bristles of two or more times the radius of fine bristles.</p>

<p>Whilst the skilled person will appreciate that the present invention may be subject to a number of modifications it is noted that the use of more than two brushes provides an unwieldy device without effectively improving sweeping as it is difficult to keep all brush heads in the correct orientation to maintain a sweeping action. Similarly, the advantages of the present invention, whilst not limited to a manual sweeping device, are most manifest in such a device, in particular, when configured as a broom.</p>

<p>Whilst the term particulate materials is used herein to relate to actual particles (i.e. materials of size less than around 1cm, the benefits of the present invention may also extend to the brushing up of incidental larger articles, such as litter, by embodiments of the present invention.</p>

<p>In the present application narrow brush heads and wide brush heads, i.e. heads more than twice the width of a narrow head are contemplated. For a broom of the invention, brush heads for manual use are typically (narrow) 20 to 60cm, preferably 30 to 40cm wide, but (broad) some brush heads, may be from 60 to 120cm wide, preferably, 70 to 90cm wide.</p>

<p>The first brush preferably has a narrow head and the second brush a broad head. The broader second brush, whilst thereby more easily follows the path of the first brush when, say, sweeping in an arc, thus providing a more efficient sweeping action. The first brush head is preferably the brush head that is foremost in nonnal use.</p>

<p>The present invention will now be described with reference to the attached drawings in which: Figure 1 shows a first side view of the present invention; Figure 2 shows a second front view of the present invent; and Figure 3 shows a partial perspective view of a boy operating the present invention.</p>

<p>Referring now to Figures 1 to 3: The sweeping device of the present invention is here exemplified in the form of a broom (10). The broom (10) comprises to brush components (12, 22) connected by a resilient means (30) in the form of a rubber band wrapped several times around both brush handles (14, 24) so as to keep the two brush components in resiliently deformable communication. The first, leading, brush component (12) comprising a brush head (16), a plurality of bristles (18) affixed to the brush head and a handle (14) extending from the brush head (16); the second brush component (22) comprises a brush head (26), a plurality of bristles (28) affixed to the brush head (26) and a handle (24) extending from the brush head (26), wherein the resilient connector (30) serves to retain said combination of brushes in resiliently moveable relation to one another in use, such that in use, both brush heads (16, 26) may be operably moved over a surface to be cleaned (2) such as to sweep up a particulate material (100).</p>

<p>The head of the second brush (22) is wider than the head of the first brush (12). Fine material disturbed but not retained by the first brush is thereby at least partially retainable by the second brush. This is particularly efficacious in normal use as a sweeper will tend to aim the narrower brush at the larger concentration of larger particles when sweeping.</p>

<p>The bristles (18) of the first brush (12) are longer than the bristles of the second brush.</p>

<p>The bristles (18) of the first brush (12) are stiffer than the bristles of the second brush.</p>

<p>The bristles (18) of the first brush (12) are less densely packed than the bristles of the second brush.</p>

<p>The bristles (28) of the second brush (22) are shorter than the bristles of the second brush.</p>

<p>The bristles (28) of the second brush (22) are finer than the bristles of the second brush.</p>

<p>The bristles (28) of the second brush (22) are more densely packed than the bristles of the second brush.</p>

<p>The bristles (18, 28) of the first brush (12) and the second brush (22) are arrayed in three consecutive parallel rows. The dimension perpendicular to these rows is termed a brush depth. This provides six effective rows of bristles when brushing, less than this may fail to retain material, more provides little incremental improvement in the retention of material being swept.</p>

<p>The handles (14, 24) of the first and second brushes are elongate rods but may be elongate cylinders so as to make them lighter and easier to use. The handles (14, 24) of the first and second brushes are cylindrical making them comfortable for manual use. The handle of the first brush is longer than the handle of the second brush making for an easier brushing action. The resilient connector (30) is located on a portion of the handle of the first broom further away from the head of the first broom (12) than the location of the resilient connector on the handle of the second broom (24) is relative to the head of the second broom. The broom handles are preferably rectilinear or straight as this provides a stiffer handle for a given usage of handle material.</p>

<p>I use a first (14) leading brush component of the broom is conveniently grasped at an upper end (34) of the handle (14) and the second (14) trailing brush component of the broom is conveniently grasped at an upper end (34) of the handle (14). The first, leading, brush (12) having coarse bristles is the first to encounter undisturbed particulate matter (100) to be swept up and that brush serves to retain (as in keep the material ahead of itself) coarse particulate material (102) but is inefficient in retaining fine particulate material (104) which is retained by the second, trailing, brush (22). The second trailing brush is, however, less efficient in retaining coarse material as it tends to ride up over that material rather than retain it, particularly when a combination of coarse and fine materials (causing close packing) is encountered.</p>
