Description

AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION Standard Patent Applicant (s): Huo-Pia WANG Invention Title: Brush having a resiliently articulated handgrip The following statement is a full description of this invention, including the best method for performing it known to me/us: l a BRUSH HAVING A RESILIENTLY ARTICULATED HANDGRIP This invention relates to a brush, more particularly to a brush having a resiliently articulated handgrip. Referring to Figure 1, a conventional pet brush 5 comprises a brushing unit 1 including a plurality of bristles 101, and a handgrip 2 disposed fixedly on the brushing unit 1. Since the handgrip 2 is disposed fixedly on the brushing unit 1, adjustments in operating posture and 10 movement are required in order to position the pet brush so that the bristles 101 of the brushing unit 1 remain effectively positioned for brushing when the bristles 101arepassedalong curvatures of a pet' s body. Therefore, operation of the conventional pet brush is inconvenient. 15 Therefore, an object of the present invention is to provide a brush having a resiliently articulated handgrip capable of pivoting in response to variations in operating conditions. According to the present invention, there is provided 20 a brush comprising a brushing unit, a handgrip, and a resilient component. The brushing unit includes a bristle-retaining member that has a first side and a second side opposite to the first side, a plurality of bristles retained on the bristle-retaining member and 25 disposedonthe firstside, andapivotconnectorprovided on the second side of the bristle-retaining member. The handgrip has a pivoted portion that is pivotally 2 connected to the pivot connector, a grip portion that is opposite to the pivoted portion, and a positioning portion that is disposed between the pivoted portion and the gripportion. The resilient component isdisposed 5 between the brushing unit and the handgrip, and provides a biasing force for urging the positioning portion of the handgrip to abut against the bristle-retaining member. The advantage of the present invention resides in 10 providing a brush with a resiliently articulated handgrip capable of pivoting relative to a brushing unit thereof when bristles of the brushing unit are passed along curvatures of a pet's body such that the bristles remain effectively positioned for brushing. 15 Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which: Figure 1 is a schematic diagram of a conventional 20 brush; Figure 2 is a schematic diagram of a first preferred embodiment of a brush having a resiliently articulated handgrip according to the present invention; Figure 3 is a schematic diagram to illustrate pivoting 25 of a handgrip of the first preferred embodiment relative to a brushing unit thereof during operation; Figure 4 is a schematic diagram of a second preferred 3 embodiment of a brush having a resiliently articulated handgrip according to the present invention; Figure 5 is a schematic diagramto illustrate pivoting of ahandgripof the second preferred embodiment relative 5 to a brushing unit thereof during operation; Figure 6 is a fragmentary exploded perspective view of a third preferred embodiment of a brush having a resiliently articulated handgrip according to the present invention; 10 Figure 7 is schematic diagram of a fourth preferred embodiment of a brush having a resiliently articulated handgrip according to the present invention; Figure 8 is a fragmentary top view of the fourth preferred embodiment; 15 Figure 9 is a schematic diagram of a fifth preferred embodiment a brush having a resiliently articulated handgrip according to the present invention; Figure 10 is a schematic diagram to illustrate pivoting of a handgrip of the fifth preferred embodiment 20 relative to a brushing unit thereof during operation; Figure 11 is a schematic diagram of a sixth preferred embodiment a brush having a resiliently articulated handgrip according to the present invention; and Figure 12 is a schematic diagram to illustrate 25 pivoting of a handgrip of the sixth preferred embodiment relative to a brushing unit thereof during operation. Figure 2 illustrates a first preferred embodiment 4 of the brush having a resiliently articulated handgrip according to the present invention. The brush comprises a brushing unit 10, a handgrip 20, and a resilient component 30. In this embodiment, the brush is used for 5 brushing pet hair. The brushing unit 10 includes a bristle-retaining member 100 that has a first side 11 and a second side 12 opposite to the first side 11, a plurality of bristles 13 retained on the bristle-retaining member 100 and 10 disposed on the first side 11, and a pivot connector 14 provided on the second side 12 of thebristle-retaining member 100. In this embodiment, the pivot connector 14 includes a pivot ear 141 projecting from the second side 12, and a pivot shaft 142 connected to the pivot ear 15 141. Preferably, the second side 12 has a lower engaging groove 121 adjacent to the pivot connector 14. The handgrip 20 has a pivoted portion 21 that is pivotally connected to the pivot connector 14, a grip portion 22 that is opposite to the pivoted portion 21, 20 and a positioning portion 23 that is disposed between the pivoted portion 21 and the grip portion 22. In this embodiment, the pivoted portion 21 of the handgrip 20 has a tip segment 24 distal from the positioning portion 23. Preferably, the tip segment 24 is formed with an 25 upper engaging groove 241 opposite to the lower engaging groove 121 of the second side 12 of the bristle-retaining member 100. The pivoted portion 21 of the handgrip 20 5 is formed with a pivot hole through which the pivot shaft 142 is extended. The resilient component 30 is disposed between the brushing unit 10 and the handgrip 20, and provides a 5 biasing force for urging the positioning portion 23 of the handgrip 20 to abut against the bristle-retaining member 100. In this embodiment, the resilient component 30 is a compression spring having opposite ends that extend respectively into the lower engaging groove 121 10 of the second side 12 of the bristle-retaining member 100 and the upper engaging groove 241 of the tip segment 24 of the handgrip 20. Under normal conditions, the resilient component 30 abuts resiliently against the second side 12 of the 15 bristle-retaining member 100 and the tip segment 24 of the handgrip 20 so as to provide the biasing force for urging the positioning portion 23 of the handgrip 20 to abut against the bristle-retaining member 100, thus maintaining an orientation of the bristle-retaining 20 member 100. As shown in Figure 3, when a user grips the grip portion 22 of the handgrip 20 and uses the bristles 13 to brush pet hair, the handgrip 20 pivots relative to the bristle-retaining member 100 as the bristles 13 are passed along curvatures of a pet's body such that 25 the bristles 13 remain effectively positioned for brushing. As a result, brushing is comparatively easier and ergonomic. When the handgrip 20 pivots away from 6 the bristle-retaining member 100 of the brushing unit 10, the positioning portion 23 separates from the bristle-retaining member 100, and the resilient component 30 is compressed. On the other hand, when the 5 usereases pressureon thehandgrip20, thebiasing force provided by the resilient component 30 urges the positioning portion 23 of the handgrip 20 to abut against the bristle-retaining member 100 of the brushing unit 10 as shown in Figure 2. 10 Figure 4 illustrates a second preferred embodiment of the brush having a resiliently articulated handgrip according to the present invention. The brush comprises a brushing unit 10', a handgrip 20' and a resilient component 30' .
