Description
[0001]The present invention relates to an electricallyoperable clipper and more particularly to an electricallyoperable animal hair clipper.
[0002]Electrically operable clippers may be used tocut hair from the coats of animals. Such clippers typicallyhave a handle by which a user is able to grip the clipper,a fixed comb and a movable clipper blade. The clipperblade is movable across the comb in a reciprocating man-ner by an electric motor provided within the handle. Atransmission arrangement is provided between the out-put shaft of the motor and the clipper blade in order toconvert the rotary motion of the output shaft to the afore-mentioned reciprocating motion of the clipper blade.[0003]According to the present invention there is pro-vided an electrically operable clipper having a body por-tion and a head portion, wherein the head portion in-cludes a movable cutter and a fixed comb, the clipperincluding an internally located electric motor operable tomove the movable cutter, wherein the clipper includesan operating switch movable between an off position, anoperating positon and a reset position, wherein the resetposition operates a motor reset module of the clipper.[0004]The present invention thus utilises a singleswitch to both operate the electric motor and to reset theelectric motor in the event that a motor cut-out event oc-curs. The present invention thus removes the need for aseparate reset switch or button to be provided on theclipper.
[0005]Movement of the operating switch from the offposition to the operating position may require movementof the switch in a first direction, and movement of theoperating switch from the off position to the reset positonmay require movement of the switch in a second direc-tion. In one embodiment of the invention the first directionmay be opposite to the second direction.
[0006]By providing the reset position of the operatingswitch in a different direction to the operating position,then in advertent operation of the motor reset is avoided.[0007]The switch may be biased from the reset posi-tion to the off position. This ensures that once a resetoperation has been made, then the switch returns to aposition ready for the next operation of the clipper.
[0008]The switch may be movable to a further oper-ating position, wherein the operating position corre-sponds to a first operating speed of the electric motorand the further operating position may correspond to asecond operating speed of the electric motor.
[0009]The operating switch may include an internalmember and an external member joined to the internalmember, where in the internal member is joined to theexternal member through a slot of the body portion. Theinternal and external members may, for example, beclipped together, joined by adhesive or connected by oneor more mechanical fasteners.
[0010]The internal member may include a pair of re-silient arms which co-operate with opposed ramp forma-
tions of the body portion. The co-operation of the armswith the ramp formations defines a detent mechanism ofthe operating switch.
[0011]The opposed ramp formations each comprise5
a plurality of inclined surfaces defining a plurality of peaksand troughs. the off position and the or each operatingposition of the switch are defined by opposing troughs ofthe opposed ramp formations. In the reset position, theresilient arms are compressed between facing inclined10
surfaces of the opposed ramp formations.
the internal member of the switch may include an abut-ment surface which contacts the motor reset modulewhen the switch is in the reset position. The abutmentsurface may be located between the resilient arms.15
[0012]An embodiment of the present invention willnow be described with reference to the accompanyingdrawings in which:
Figure 1 shows a perspective view of a clipper in20

Figure 3 shows a bottom plan view of the clipper;Figure 4 shows a top plan view of the clipper;
Figure 5 shows a partially cutaway side view of the25
clipper;
Figure 6 shows a perspective view of a motor of theclipper;
Figure 7 shows a bottom plan view of the interior ofa portion of the handle of the clipper;

Figure 8 shows a sectional view indicated by arrowsA-A on figure 7;
Figures 9 to 14 show bottom plan views of the inter-action of switch detent mechanism of the clipper;Figure 15 shows a plan view of a switch slider of the35
clipper;
Figure 16 shows the cross-sectional view indicatedby arrows B-B on figure 15; and
Figure 17 shows a perspective view of the switchslider.

[0013]Referring firstly to figures 1 to 4, there is showna handheld clipper generally designated 10. The clipper10 is configured for the cutting of the hair of animals, forexample bovine and ovine hair.

[0014]The clipper 10 comprises a body portion 12 andhead portion 14. The body portion 12 is intended to begripped by the hand of a user of the clipper 10 and isprovided with a slidable switch 16. The switch 16 is po-sitioned and configured such that it can be manipulated50
by the thumb of a user while gripping the clipper 10 inone hand.
[0015]The head portion 14 of the clipper 10 includesa fixed comb 18 and a movable cutter 20. The cutter 20is movable in an arc across the comb 18 in a reciprocating55
manner by a drive mechanism of the clipper 10. The headportion 14 further includes a tension nut 22 which can bemanipulated by a user of the clipper 10 to vary the contactpressure between the cutter 20 and the comb 18. In an
