This invention relates to brushes, particularly to paint brushes and cleaning brushes and more particularly to vibrating brushes.
One form of known vibratory paint brush is disclosed in US 2004/0205914. One aim of the present invention is to provide an improved vibrating brush.
According to one of its aspects, the present invention provides a paint brush in accordance with claim 1. Other aspects of the invention are defined in other independent claims. The dependent claims define preferred or alternative embodiments.
One embodiment of the present invention comprises an active brush ie a brush fitted with an integral vibration mechanism; in this case, the brush is preferably provided with an actuator to turn the vibration mechanism on or off. This may facilitate alternating between using the brush in an active, vibrating mode and using it in a passive, non-vibrating mode. An alternative embodiment of the present invention comprises a passive brush ie not having a vibration mechanism.
Where a tapered connection is provided between a detachable brush head and a handle it is preferably self holding or self locking; it is preferably the only means provided for retaining the detachable brush head and the handle together. A self holding or self locking taper connection may be particularly advantageous for a vibrating brush as it may alleviate the tendency of other forms of connection (for example cylindrical screws or clips) to vibrate and/or work themselves loose. Furthermore, such a connection may ensure that the available vibrational energy is transmitted through the connection without loss of vibrational energy in or due to the mechanical fixing.
The connection between a detachable brush head and the handle is preferably provided by an interaction between surfaces as opposed to a point contact or series of point contacts. This may provide stability and or rigidity to the connection.
A cone form of connection may facilitate mounting and dismounting of the detachable brush head, for example using a slight rotation. It may also permit the user to select the orientation of the detachable brush head with respect to the handle. This may be particularly useful when using a flat form of brush head; when a user grips the handle in any particular way, the cone form of connection allows the rotational position of the brush head to be orientated at will relative to the handle. This may provide a more comfortable painting position.
The connection between the handle and the brush head is preferably a cone-in-cone connection. A morse cone may provide a particularly convenient form.
A connector having the form of a bore may be at greater risk of damage than a connector having the form of a trunion, especially in respect of the lip of the bore when made of a plastics material. Arranging for the tapered handle connection surface to be provided on a trunion may reduce the risk of damage to the handle; a damaged brush head may be more easily replaced than a damaged handle, especially when the handle incorporates a vibrating mechanism.
The taper length may be within the range 10 to 30 mm and/or the taper angle may be within the ranges 0.5° to 12.5°, 1° to 25°, 1° to 2° or 2 to 4°. Such configuration may facilitate assembly and/or disassembly and/or self locking of the connectors.
Particularly in the case of a passive paint brush, the handle may comprise wood or plastics. It may comprise an injection moulded plastics and/or a combination of plastics, for example a resilient plastics core and a softer plastics contact surface adapted to provide an agreeable feel or touch for the user.
Providing at least one of the tapered connection surfaces on a lining, for example a plastics or metal lining may:
-
- facilitate selection of a desired friction characteristic, hardness and/or resilience;
- allow the tapered connection surface to be removable and/or replaceable;
- facilitate incorporation of the tapered connection surface by allowing this to be provided on a separate piece rather than as an integral part of the handle or brush head.
Where a damper is provided this may provide sufficient damping to allow a paint brush to be used comfortably in its vibrating mode and sufficient rigidity to allow such a paint brush to be used as an ordinary, non-vibrating paint brush. This may allow:
-
- the vibrating mode of the brush to be used for delicate painting portions, for example painting of a straight line, painting up to a border (for example the edge of a wall mounted light switch or cornice); and
- the non-vibrating mode to be used for applying paint more quickly away from such delicate portions.
This may increase the overall efficiency of applying paint to walls, panels, doors and other surfaces. Furthermore, the facility and accuracy afforded for precision painting may
-
- allow non-professional decorators to easily carry out such painting; and/or
- allow professional decorators to complete such precision painting in a manner that is less tiring and/or quicker.
The nature of any vibration provided is preferably such that:
-
- The paint has a tendency to move towards the free end of the bristles to facilitate accurate application to a surface;
- Use of masking paper or tape can be reduced or eliminated;
- The paint is retained within the brush head and will not spatter.
The weighted displacement of the brush head relative to the handle, particularly the grip portion of the handle, when subjected to an external force may provide one indication of the brush's suitability for use in a non-vibrating mode. This may be assessed by maintaining the grip portion of the handle horizontal, suspending a mass of 400 g on a wire from the brush head at a position corresponding to the root of the bristles and measuring the angle of displacement of the brush head relative to the grip portion of the handle. The suspended mass of 400 g is representative of the force that will be exerted on the brush head when the brush is used for painting in a passive, non-vibrating mode. A displacement of less than 18°, preferably less than 15° provides desirable passive painting characteristics. The displacement may be greater than 5° or greater than 8°. These characteristics may be provided essentially by the damper and/or by the damper in combination with the way it is secured to the handle.
The held vibration sensation may be:
-
- Less than 35%, preferably less than 30%; and/or
- Greater than 10%, particularly greater than 15%;
of the full vibration.
This ensures that:
-
- the vibration felt by a user holding the grip portion of the handle is not uncomfortable or unduly tiring;
- there is suitable separation between the grip portion of the handle and the active portion of the handle to allow adequate vibration of the brush head; and
- the vibration of the active portion of the handle is transferred primarily to the brush head and not “lost” in vibrating the grip portion of the handle.
An explanation of measurement of the held and full vibration is given in relation to the accompanying figures.
Particularly in the case of a paint brush, the bristles of the brush head may comprise a mixture of synthetic bristles and natural bristle, for example of pig hair. The bristles may comprise:
-
- between 15% and 45% synthetic bristles (preferably between 20% and 40%); and
- between 55% and 85% natural bristles (preferably between 60% and 80%);
The synthetic bristles may facilitate precision for application of paint to a surface and the natural bristles may provide advantageous paint retention and/or capillary action. This combination may be particularly advantageous in respect of a vibrating paint brush to ensure that the paint has a tendency to move towards the free end of the bristles to facilitate accurate application to a surface and yet is retained within the brush head and will not spatter.
Alternatively, the bristles may consist of synthetic bristles.
The bristles may be:
-
- greater than 35 mm, preferably greater than 40 mm in length; and/or
- less than 100 mm, preferably less than 80 mm, more preferably less than 65 mm in length.
This may provide a suitable amount of resilience and/or movement and/or resonance in the bristles to enhance any vibration movement.
In the case of a rectangular form brush head the bristles are preferably between 35 mm and 55 mm in length.
In the case of a cylindrical form brush head, the bristles are preferably between 50 mm and 70 mm in length.
The bristles of a rectangular form brush head may form a brush head having
-
- a bristle width of:
- Greater than 20 mm, preferably greater than 25, more preferably greater than 30 mm; and/or
- Less than 100 mm, preferably less than 80 mm, more preferably less than 70 mm; and/or
- a bristle thickness
- Greater than 5 mm, preferably greater than 8 mm, and/or
- Less than 30 mm, preferably less than 20 mm, more preferably less than 15 mm.
- a bristle width of:
The bristles of a cylindrical form brush head may form a brush head having a diameter:
-
- Greater than 10 mm, preferably greater than 15 mm, and/or
- Less than 25 mm, preferably less than 22 mm, more preferably less than 20 mm.
The length of bristles defined above is the free length, particularly the length projecting from a ferrule or attachment securing the bristles in place. The thickness, width and diameter are those at the base of the bristles.
The combination of desired dampening and rigidity of the damper when assembled in the brush may be achieved by a damper which comprises or consist essentially of a material having a shore hardness in the range 45 to 75, preferably 50 to 60. The dampening/rigidity properties may also be influenced by the fixation of the damper to the handle. Preferably, the damper is secured to the handle by a gripping or clamping arrangement, more preferably between plates or flanges. Contact between the damper and the handle may be arranged around the entire or substantially the entire periphery of the damper. This may help to maximise the contact between the damper and the handle. Arranging the damper to be of substantially cylindrical cross section may facilitate mounting and/or contact with the handle. Whilst an adhesive may be used, assembly is facilitated if no adhesive is used in the damper mounting.
Arranging for at least one stop to be provide, preferably as part of the damper, may reduce the risk of the damper becoming damaged or dislodged, for example, by excessive movement between the parts of the handle to which it is attached. The stop or stops preferably act over 360°, i.e. they are effective at each position around the perimeter of the brush to limit the angle of displacement between the active and grip portions of the handle.
A vibration movement which comprises a translation, possibly as part of a rotational movement, may provide an effective vibration action.
The vibrator may comprise a motor having an eccentric mass connected to its spindle. The axis about which the eccentric mass rotates is preferable co-axial with the handle; it is preferably coaxial with the length of the bristles of the brush. The vibrational movement of the bristles is preferably substantially perpendicular to their length.
A motor adapted to rotate at a speed within the range 6000 to 8000 rpm, having a mass in the range 5 to 7 g, preferably 5.2 to 6.3 g arranged with an eccentricity with respect to the axis of the motor within the range 2 to 4 mm may provide a particularly advantageous form of vibration, particularly for painting applications.
A motor adapted to rotate at a speed within the range 7000 to 10000 rpm with a mass in the range 5 to 7 g, preferably 5.2 to 6.3 g arranged with an eccentricity with respect to the axis of the motor within the range 2 to 4 mm may provide a particularly advantageous form of vibration, particularly for cleaning applications.
The direction of rotation of the motor may be selectable by the user, for example by means of a switch.
An amplitude measured at the root of the bristles in the range 1.5 to 3.5 mm, preferably in the range 2 to 3 mm and a frequency in the range 60 to 100 Hz, preferably 75 to 85 Hz may provide a particularly advantageous form of vibration, particularly for a paint brush.
An amplitude measured at the root of the bristles in the range 2 to 4 mm, preferably in the range 2.5 to 3.5 mm and a frequency in the range 80 to 120 Hz, preferably 90 to 110 Hz may provide a particularly advantageous form of vibration, particularly for a cleaning brush.
The vibration of the brush, brush head or bristles may be a vibration obtainable with any of the configurations described herein.
The brush, when configured as a paint brush, may be used with one or more of: acrylic paint; glycarophtalic paints; water based paints; resin based paints; solvent based paints; varnishes; paints in gel form. Paint brushes according to the invention are particularly useful for decoration eg applying paint to walls, doors, window frames and building panels.
The brush may be adapted to be used with a plurality of interchangeable brush heads; these may be selected from paint brush heads, cleaning brush heads, polishing brush heads.
A particularly advantageous configuration in accordance with the invention is the combination or association of (i) a handle having a handle connector and/or (ii) a brush head having a head connector and/or (iii) a brush head receptacle, in which the handle connector and the head connector are configured to permit assembly, retention and disassembly of the handle and the brush head, and in which the brush head receptacle comprises an attachment adapted to releasably retain the brush head within the receptacle.
One use of such a configuration is in relation to paint brushes. A sequence of painting using such a configuration may comprise one or more of the steps of:
-
- fitting a first paint brush head to the handle and completing a first painting task (for example using a rectangular paint brush head to paint a substantially straight portion of a wall adjacent to a cornice);
- disassembling the first paint brush head from the handle and storing the first paint brush head in a brush head receptacle;
- fitting a second paint brush head to the handle and completing a second painting task (for example using a round paint brush head to paint a corner of a wall adjacent to a cornice);
- disassembling the second paint brush head from the handle and storing the second paint brush head in a brush head receptacle;
- removing the first paint brush head from its receptacle and re-assembling it with the handle for use in a third paining task.
Any aspect of this invention may be used alone or in combination in relation to various brushes, particularly paint brushes and cleaning brushes.
Embodiments of the invention will now be described, by way of example only, with reference to:

The detachable brush head 42 has its bristles 43 arranged as a round or conical brush head and is attached and secured to the active, vibrating portion 13 of the handle 11 by cooperation between a morse cone trunion provided at the end of the handle 11 and a corresponding morse cone bore provided within the brush head 42.
In use, a painter will generally hold the grip portion 14 of the handle 11. The vibrator may be activated particularly to facilitate application of paint in a border zone along a border or at in intersection between two surfaces. The vibrator may be turned off and the brush used as an ordinary paint brush, for example, to apply paint from the border zone towards a large area to be painted. The remaining, large surface may then be painted with a roller.
The term flat brush head is intended to denote a generally rectangular form of brush head, for example as illustrated in
The detachable brush head 62 has a head connector 63 having a tapered head connection surface 64 corresponding in form and angle to the tapered handle connection surface 54.
The motor 102 is powered by batteries housed within the grip portion 14 of the handle via an on/off switch 105 and wire (not shown) which passes through a bore 151 of the damper. The batteries 14 may provide a counterweight to the motor 102 to make the handle more comfortable to hold and manipulate, for example by being spaced from the damper 15 by an intervening space 106. An alternative or additional counterweight may be provided.
In
In the
The damper 15 shown
The intervening portion 93 of the damper 90 comprises a first stop 98 and a second stop 99 in the form of spaced flanges which project from the body of the damper toward the periphery of the handle 97 and are separated by a recess 141. These stops 98, 99 provide a physical limitation to possible rotational displacement between the active 13 and grip 14 portions of the handle if the grip portion 14 of the handle is moved in direction 142 and the active portion 13 of the handle is moved in direction 143 so as to pivot about the damper 15. The circular nature of the stops 98, 99 enables them to act irrespective of the orientation of such bending about the axis 144 of the handle.
-
- a rest position 152 of this portion of the paint brush before the vibrator is turned on,
- that when the vibrator is turned on the bristle roots initially have a spiral movement 153 orthogonal to their length,
- that when the vibrator is stable, each bristle root has a substantially similar movement 154 orthogonal to its length which, when allowed to move freely, is substantially circular with an amplitude a of about 2 mm and a frequency of about 80 Hz.
When the vibrating brush head is placed against a surface to be painted for example with the bristles at about 45° to the surface, as represented schematically in
The holding structure of the contact points 171, 172 (which may be metal spikes) is arranged and given a suitable inertia such that it does not significantly affect the vibration characteristic being measured.
The following results were obtained measured for two different dampers:
The lid 208 comprises an attachment 209 adapted to removeably secure the lid 208 and a paint brush head 201 together. In this embodiment, the attachment 209 comprises a tapered connection surface 210 in the form of a cone adapted to cooperate with a corresponding, conical tapered connection surface 203 of the paint brush head 201. The lid 208 may be easily removed from the container portion 205 to allow the lid 208 and the paint brush head 201 to be assembled or disassembled.
In use, the paint brush head 201 is suspended from the attachment 209 of the lid 208 such that its bristles 202 do not touch the base 207 of receptacle 200. Preferably, the receptacle 200 stands on its base. However, in preferred embodiments, even if the receptacle 200 falls over or sits on its side, the bristles 202 of the paint brush head 201 do not touch the walls of the receptacle 200.
Graduations 213 are provided at the side wall of the receptacle to indicate a suitable level to which a liquid may be introduced prior to inserting a brush head. The different graduations may take account of the different displacement of different sizes of brush heads that may be placed within the receptacle.
The receptacle may be used for temporary storage of a paint brush head prior to reuse, for example to facilitate storage without drying of a brush head whilst a decorator uses an alternative brush head or takes a break. This may avoid the necessity of cleaning the brush head prior to reuse in such circumstances or wrapping it in a rag or in plastic film. The receptacle may be used for cleaning or partial cleaning of a brush head, the paint attached to the bristles having a tendency to fall to the base of the receptacle when suspended in water or another suitable cleaning fluid. A receptacle containing a brush head and a cleaning fluid may be agitated, for example shaken, and/or left to settle to facilitate this. The receptacle may also be used for more permanent storage of paint brush heads, either with or without the presence of a liquid, the absence of contact between the bristles and the receptacle being advantageous for avoiding deformation of the bristles.
The
The distance 216 between the base 207 of the receptacle and the bristles of a brush retained at in the receptacle by the attachment 209 may be greater than 5 mm or 10 mm; it may be less than 40 mm or 30 mm. Such a configuration may provide a space separated from the bristles at which sediment may collect; it may enable a compact configuration of the receptacle.
Whilst a receptacle has been described in relation to a particular paint brush, receptacles may be may be used with other types of bushes and/or brush heads.
