Abstract

The present disclosure relates to a releasable attachment comb ( 60 ) for a blade set ( 22 ) of a cutting head ( 20 ) of a hair cutting appliance ( 10 ), said attachment comb ( 60 ) comprising a supporting frame ( 62 ) comprising a first lateral grip bar ( 68 ), a second lateral grip bar ( 70 ), and at least one laterally extending supporting bar ( 64, 66 ) arranged between the first lateral grip bar ( 68 ) and the second lateral grip bar ( 70 ); a plurality of guide teeth ( 72 ) that define a skin contact front face ( 74 ); a plurality of snap-on mounting elements ( 78, 80 ); wherein the snap-on mounting elements ( 78, 80 ) are spaced away from the first lateral grip bar ( 68 ) and the second lateral grip bar ( 70 ); wherein at least one of the snap-on mounting elements ( 78, 80 ) is configured as a proximal snap-on mounting element ( 78 ) that is arranged on a first, proximal side ( 84 ); wherein at least one of the snap-on mounting elements ( 78, 80 ) is configured as a distal snap-on mounting element ( 80 ) that is arranged on a second, distal side ( 86 ); and wherein the at least one proximal snap-on mounting element ( 78 ) and the at least one distal snap-on mounting element ( 80 ) are arranged to mutually lock therebetween the blade set ( 22 ) to attach the attachment comb ( 60 ) to the cutting head ( 20 ). The present disclosure further relates to a cutting head ( 20 ) of a hair cutting appliance ( 10 ) that is fitted with a respective attachment comb ( 60 ).

First claim

The invention claimed is:

1. A releasable attachment comb assembly comprising:
a substantially rectangular plate forming a distal side of said attachment comb assembly, said substantially rectangular plate comprising:
a first longitudinal edge;
a second longitudinal edge;
a first lateral edge extending between said first longitudinal edge and said second longitudinal edge; and
a second lateral edge extending between said first longitudinal edge and said second longitudinal edge;

a first lateral side extending substantially vertically from said first lateral edge;
a second lateral side extending substantially vertically from said second lateral edge; and
a bar extending between a top edge of said first lateral side and a top edge of said second lateral side, said bar forming a proximal side of said attachment comb assembly;
a plurality of teeth extending from said first longitudinal edge of said substantially rectangular plate toward said proximal side of said attachment comb assembly;
a plurality of cutout sections within said substantially rectangular plate, said cutout sections extending from said second longitudinal edge toward said first longitudinal edge, wherein a distal mounting element is formed between two of said plurality of cutout sections, said distal mounting element comprising a protrusion extending substantially vertically from said distal mounting element toward said bar, said protrusion narrowing a space within said releasable attachment comb assembly; and
a proximal mounting element extending from said bar toward said plurality of teeth, said one proximal mounting element comprising a protrusion extending substantially vertically from said proximal mounting element toward said rectangular plate, wherein said protrusion of said proximal mounting element narrowing a space within said releasable attachment comb assembly, wherein said distal mounting element and said proximal mounting element are configured to:
deflect outwardly when contacted.

2. The releasable attachment comb assembly of claim 1 , wherein said distal mounting element comprises:
a first distal mounting element proximate to said first lateral side; and
a second distal mounting element proximate to said second latter side.

3. The releasable attachment comb assembly of claim 1 , wherein said at least one proximal mounting element comprises:
a first proximal mounting element proximate to said first lateral side; and
a second proximal mounting element proximate to said second lateral side.

4. The releasable attachment comb assembly of claim 1 , wherein said protrusion of said distal mounting element comprises a ramp extending from said second longitudinal edge of said substantially rectangular plate, wherein a length of said ramp is less than a length of said cutout portion.

5. The releasable attachment comb assembly of claim 1 , wherein said protrusion of said at least one proximal mounting element comprises a ramp extending from said bar, wherein a length of said ramp is less than a length of said proximal mounting element.

6. The releasable attachment comb assembly of claim 1 , further comprising a second distal mounting element formed between two of said plurality of cutout sections, said second distal mounting element comprising a protrusion extending substantially vertically from said second distal mounting element toward said bar, said protrusion narrowing a space within said releasable attachment comb assembly, said second distal mounting element configured to: deflect outwardly when contacted.

7. The releasable attachment comb assembly of claim 1 , further comprising: a second proximal mounting element, said second proximal mounting element comprising a protrusion extending substantially vertically from said second proximal mounting element toward said rectangular plate, wherein said protrusion of said second proximal mounting element narrowing a space within said releasable attachment comb assembly, said second proximal mounting element configured to: deflect outwardly when contacted.
