Definitions

  • This invention relates to brushes, particularly to paint brushes and cleaning brushes and more particularly to vibrating brushes.
  • 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.
  • 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.
  • 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.
  • 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 30mm and/or the taper angle may be within the ranges 0.5 > to 12.5 > , P to 25 > , P to 2Or 2 to 4°. Such configuration may facilitate assembly and/or disassembly and/or self locking of the connectors.
  • 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.
  • a lining for example a plastics or metal lining may:
  • a damper 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 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 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 400g 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 40Og 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 18P, preferably less than 15° provides desirable passive painting characteristics.
  • the displacement may be greater than 5Or greater than 8P.
  • the held vibration sensation may be:
  • 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:
  • 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.
  • the bristles may consist of synthetic bristles.
  • the bristles may be:
  • This may provide a suitable amount of resilience and/or movement and/or resonance in the bristles to enhance any vibration movement.
  • the bristles are preferably between 35 mm and 55 mm in length.
  • 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
  • the bristles of a cylindrical form brush head may form a brush head having a diameter:
  • 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.
  • 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.
  • 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 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 36CP, 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 6.3g 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 6.3g 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.
