Definitions
- the present disclosure relates to a hair cutting system and is particularly, although not exclusively, concerned with a hair cutting system that improves the capturing of cut hairs.
- cut hairs are typically allowed to fall away from a hair cutting apparatus on to and around the person whose hair is being cut. This can cause annoyance to both the one giving and the one receiving a haircut.
- the hair cutting process is particularly desirable for the hair cutting process to be made as comfortable as possible when a child is being given a haircut. Cut hairs on the child's skin can cause itchiness and irritation, adding to the concerns of the person giving the haircut and possibly leading to poor haircut results.

- a maximum clearance value of the range may be selected such that cut hairs are restricted from passing between the distal end 140a of the comb and the front wall 164 when the clearance 150 is at the maximum value.
- a minimum clearance value of the range may be selected in order to prevent the comb from interfering with the front wall 164 as it moves.

Abstract
A hair cutting system (100) is provided, the system comprising a hair cutting appliance (120) comprising one or more pairs of cutting blades (124) for cutting hair a comb (140) arranged forwards of the cutting blades and configured to guide hair towards the cutting blades; and a hair collector (160), the hair collector comprising a hair chamber (168) for receiving hair cut by the hair cutting appliance and a coupling portion (170) configured to couple the hair collector to the hair cutting appliance. A hair collector for the hair cutting system is also provided.
Description
- The present disclosure relates to a hair cutting system and is particularly, although not exclusively, concerned with a hair cutting system that improves the capturing of cut hairs.
- During hair trimming, cut hairs are typically allowed to fall away from a hair cutting apparatus on to and around the person whose hair is being cut. This can cause annoyance to both the one giving and the one receiving a haircut.
- Cleaning up hairs after a haircut requires time and effort. Additionally, cut hairs that fall on the skin, e.g. of the neck, face, back, arms and/or hands, during the haircut can cause itchiness and irritation, which can make the hair cutting process uncomfortable.
- It is particularly desirable for the hair cutting process to be made as comfortable as possible when a child is being given a haircut. Cut hairs on the child's skin can cause itchiness and irritation, adding to the concerns of the person giving the haircut and possibly leading to poor haircut results.
- According to an aspect of the present disclosure, there is provided a hair cutting system comprising: a hair cutting appliance comprising one or more pairs of cutting blades for cutting hair; a comb arranged forwards of the cutting blades, e.g. as seen in the direction of movement (the cutting direction) of the hair cutting appliance, and configured to guide hair towards the cutting blades; and a hair collector, the hair collector comprising a hair chamber for receiving hairs cut by the hair cutting appliance and a coupling portion configured to couple the hair collector to the hair cutting appliance.
- The comb and the hair collector may be configured such that, when the hair cutting system is assembled, a portion of the comb, e.g. a distal portion of the comb, is arranged within the hair chamber.
- A wall of the hair chamber, e.g. a front wall of the hair chamber, may extend, e.g. from the hair cutting appliance, over and forwards, e.g. in the cutting direction, of the distal end of the comb, e.g. an end of the comb furthest from the hair cutting appliance along the comb.
- The wall of the hair chamber, e.g. the front wall of the hair chamber, may comprise an aperture. The comb may be configured such that a distal end of the comb extends into or through the aperture, e.g. when the hair cutting system is assembled.
- An opening of the hair chamber for receiving hair may be substantially covered by the comb or the cutting blades and the comb, e.g. such that hair leaving the hair chamber passes through the cutting blades or the comb.
- The comb may comprise a plurality of comb teeth. The comb teeth may be spaced laterally across the comb, e.g. perpendicular to the cutting direction. A spacing between the comb teeth may be approximately 3.8mm, e.g. in order to restrict hairs from passing out of the hair chamber between the teeth of the comb. The spacing between the comb teeth may be less than or equal to 6.8mm, less than or equal to 6mm, less than or equal to 5mm, less than or equal to 4mm or less than or equal to 3mm. The spacing between the comb teeth may be greater than or equal to 1mm, greater than or equal to 2mm, or greater than or equal to 3mm.
- The spacing between the comb teeth may be between approximately 3.8mm and approximately 6.8mm, e.g. less than or equal to 6.8mm and greater than or equal to 3.8mm. In some arrangements, the spacing between the comb teeth may be between approximately 1mm and 6.8mm, e.g. greater than or equal to 1mm and less than or equal to 6.8mm. Alternatively, the spacing between the comb teeth may be between approximately 1mm and 3.8mm, e.g. greater than or equal to 1mm and less than or equal to 3.8mm.
- The hair collector may comprise a base wall configured to engage, or be aligned, with a surface of a body of the hair cutting appliance when the hair collector is coupled to the hair cutting appliance. A free edge of the base wall may at least partially define an opening of the hair chamber.
- The hair cutting appliance may comprise a recess configured to receive at least a portion of the base wall of the hair collector.
- An inside, e.g. interior, surface of the base wall may be oriented substantially perpendicularly to a hair cutting plane of the hair cutting appliance, e.g. a plane in which hair are cut by the cutting blades of the hair cutting appliance, at the free edge, e.g. at the opening of the hair collector. The inside surface of the base wall may be substantially aligned with the surface of the body of the hair cutting apparatus at a position away from the free edge. The base wall may comprise a corner portion at which the orientation of the inside surface of the base wall changes.
- The base wall may comprise a curved wall portion. The orientation of the base wall, e.g. the inside surface of the base wall, may transition over the curved wall portion from being substantially perpendicular to the hair cutting plane at the edge to being substantially aligned with the surface of the hair cutting appliance body away from the free edge.
- The base wall may comprise a ramped portion extended from the free edge, e.g. in to the hair chamber. The ramped portion may define a hair flow surface substantially perpendicular to the hair cutting plane of the cutting blades. The thickness of the base wall may change over the ramped portion from an edge thickness at the free edge to a wall thickness away from the free edge. The edge thickness may be less that the wall thickness.
- The base wall may comprise a wall portion on an opposite side of the ramped portion to the free edge. The wall portion may be substantially aligned, or engaged, with the surface of the body of the hair cutting appliance.
- The wall portion may be at a lower angle relative to the hair cutting plane, e.g. less perpendicular to the hair cutting plane, compared to the hair flow surface.
- In other words the base wall of the hair collector may comprise a first angled portion adjacent the free edge and a second angled portion on an opposite side of the first angled portion to the edge, wherein the first angled portion, e.g. an inside surface of the first angled portion, may be angled more relative to the hair cutting plane of the hair cutting appliance, than the second angled portion. In other words, the first angled portion may be more perpendicular to the hair cutting plane that the second angled portion.
- The cutting blades of the hair cutting appliance may extend from a distal end of the body of the hair cutting appliance. The free edge of the base wall may be substantially aligned with the distal end of the body of the hair cutting appliance, e.g. adjacent to the cutting blades. Hence, the opening of the hair chamber may be substantially aligned with the distal end of the body of the hair cutting appliance. The hair chamber may be enclosed on three or more sides of the chamber at the opening.
- The comb may define a comb surface to be held against a user's skin when operating the hair cutting system. The comb surface may be selectively offset from the cutting blades by a hair cutting length, such that a length of hair cut by the hair cutting system is determined according to the hair cutting length.
- The comb may be movable relative to the cutting blades, e.g. in a direction perpendicular to the cutting direction of the hair cutting appliance, in order to vary the length of hair cut by the hair cutting system. The comb and the hair collector may be configured such that a clearance between a distal end of the comb and an inside surface of the hair chamber is substantially constant as the comb moves. Alternatively, the clearance between the distal end of the comb and the inside surface of the hair chamber may vary, e.g. within a range of clearance values, as the comb moves.
- The hair collector may further comprise a hair retaining wall between a closed end of the hair chamber and the opening of the hair chamber. The hair retaining wall may extend from the base wall into the hair chamber.
- The hair retaining wall may extend away from the base wall in a direction substantially perpendicular to the hair cutting plane of the cutting blades or a cutting direction of the hair cutting appliance.
- According to another aspect of the present disclosure, there is provided a hair collector for the above-mentioned hair cutting system, wherein the hair collector comprises a hair chamber for receiving hair cut by the hair cutting appliance and a coupling portion configured to couple the hair collector to the hair cutting appliance, such that a distal portion of the comb is arranged within the hair chamber.
- According to another aspect of the present disclosure, there is provided a hair collector for the above-mentioned hair cutting system, wherein the hair collector comprises a hair chamber for receiving hair cut by the hair cutting appliance and a coupling portion configured to couple the hair collector to the hair cutting appliance.

Figs. 1 and 2 , a previously proposedhair cutting system 2 comprises ahair cutting appliance 40, acomb 60 configured to guide hair towards cuttingblades 42 of thehair cutting appliance 40 to be cut, and ahair collector 80 for receiving and storing the hair cut by thehair cutting appliance 40. - The
hair cutting appliance 40 comprises abody 44 including agrip portion 46 to be held by a user when the hair cutting system is in use. Thecutting blades 42 may protrude from adistal end 44a of thebody 44. - As depicted in
Fig. 2 , thehair cutting system 2 is adjustable such that the position of acomb surface 62 of thecomb 60 can be adjusted relative to thebody 44 of thehair cutting appliance 40 and thecutting blades 42. - In use, the
comb surface 62 is held against the skin of the person whose hair is being cut and thehair cutting system 2 is moved over the person's skin in a cutting direction C, in order to cut the person's hair. - The length of hair cut by the
hair cutting system 2 is controlled by adjusting the distance between thecomb surface 62 of thecomb 60 and thecutting blades 42 of thehair cutting appliance 40. - As shown in
Figs. 1 and 2 , thehair collector 80 is coupled to thecomb 60, such that thehair collector 80 moves together with thecomb 60 as the position of thecomb surface 62 is adjusted. - The
hair collector 80 comprises a plurality ofwalls hair collection chamber 88 for receiving the cut hair. In particular, thehair collector 80 comprises abase wall 82 which is positioned adjacent to the body of the hair cutting appliance, afront wall 84 opposite thebase wall 82 and two ormore side walls 86 between thebase wall 82 and thefront wall 84. Anopening 89 of thehair collection chamber 88 is defined byfree edges hair collector - As depicted, when the
hair collector 80 is coupled to thecomb 60, part of thecomb 60 is arranged over the opening 89 of thehair collection chamber 88 and acts to restrict hairs from leaving thehair collection chamber 88. Because thehair collector 80 is coupled to the comb and moves together with thecomb 60, thecomb 60 continues to restrict hairs from leaving thehair collection chamber 88 as the hair cutting length is adjusted. - As shown in
Figure 1 , thefree edge 82a of thebase wall 82, which partially forms theopening 89 of thehair collection chamber 88, is offset from thedistal end 44a of thebody 44 of the hair cutting appliance, e.g. away from thecomb surface 62, so that thebase wall 82 does not interfere with thecutting blades 42 of the hair cutting appliance when thecomb 60 is moved away from thehair cutting appliance 40 to adjust the hair cutting length, e.g. as shown inFig. 2 . - Because the
free edge 82a of the base wall is offset from thedistal end 44a of thebody 44, agap 90 may be present between thebody 44 of thehair cutting appliance 40 and theside walls 86 of thehair collector 80, which may allow hairs to fall out of thehair collection chamber 88, particularly when the distance between thecomb surface 62 and thecutting blades 42 is at a minimum, and the distance between the cuttingblades 42 and thefree edge 82a of the base wall is at a maximum, as depicted inFig. 1 . - With reference to
Figs. 3a and3b , ahair cutting system 100 according to arrangements of the present disclosure, comprises ahair cutting appliance 120, acomb 140 and ahair collector 160. - The
hair cutting appliance 120 may be similar to thehair cutting appliance 40 and the features described above with reference to thehair cutting appliance 40 may apply equally to thehair cutting appliance 120. - The
hair cutting appliance 120 comprises abody 122, having agrip portion 123, and cuttingblades 124 for cutting hair. As depicted, thecutting blades 124 may protrude from adistal end 122a of thebody 122. - The
hair cutting appliance 120 may further comprise one ormore coupling portions 128 configured to allow thehair collector 160 to be coupled to thehair cutting appliance 120, as described below. - In the arrangement shown, the
cutting blades 124 comprise a pair of blades including a moving blade and a stationary blade (which may be referred to as a comb or guard blade). The moving and stationary blades each comprise a plurality of teeth, the teeth of the stationary blade corresponding to the teeth of the moving blade. The moving blade is driven by a motor of the hair cutting appliance to perform a reciprocating, oscillating or rotating motion relative to the stationary blade, opening and closing gaps between the respective corresponding teeth of the moving and stationary blades. When the gaps are open, hairs can be received between the teeth and the hairs are then cut when the gaps are closed. In some arrangements, the teeth of both the moving and stationary blades may comprise sharpened edges. Alternatively, the teeth of the moving or of the stationary blade may not be sharpened and the hairs may be cut by the action of the sharpened blade over the blunt edge of the unsharpened blade. Thecutting blades 124 are arranged to cut hair in a cuttingplane 126 defined by the cutting blades. The present disclosure may also apply to hair cutting appliances comprising different arrangements of cutting blades or other cutting elements for cutting a person's hair. - The
comb 140 comprises aplurality comb teeth 142 spaced laterally across thecomb 140, e.g. in a direction parallel to the cuttingplane 126 and perpendicular to the cutting direction C. Thecomb teeth 142 are shaped and arranged to lift hair away from the skin and guide the hair towards the cuttingblades 124 as thehair cutting system 100 is moved in a cutting direction C, e.g. so that the hair can be more easily received in the gaps between the moving and stationary blades. - The
comb 140 defines acomb surface 144 that is rested against the skin of the person whose hair is being cut when thehair cutting system 100 is in use. As described above, the length to which hair is cut by the hair cutting system is determined according to the distance between thecomb surface 144 and thecutting blades 124. - The
comb 140 comprises acoupling portion 146 configured to movably couple thecomb 140 to thehair cutting appliance 120, to enable to comb 140 to be moved relative to hair cutting appliance to adjust the hair cutting length. Thecomb 140 may be movable relative to thehair cutting appliance 120 between a retracted position, as depicted inFig. 4 , and an extended position, as depicted inFig. 5 . - The
comb teeth 142 comprisefirst portions 142a that extend from thecoupling portion 146 in the cutting direction C. Thecomb surface 144 may be at least partially formed by thefirst portions 142a of the comb teeth, e.g. the lower surfaces of thefirst portions 142a. Thecomb teeth 142 further comprisesecond portions 142b, which extend from the respective firstcomb teeth portions 142a to adistal end 140a of thecomb 140. As shown, thesecond portions 142b of the comb teeth may extend in a direction with a component perpendicular to thecomb surface 144, e.g. away from the comb surface. For example, thesecond portions 142b of the comb teeth may extend in a direction substantially perpendicular to thecomb surface 144. - The
second portions 142b of the comb teeth may provide support for hairs that have been lifted away from the skin, as the hairs are guided towards the cuttingblades 124. Additionally, thesecond portions 142b of the comb teeth may restrict hairs from falling out of thehair collector 160, as described below. - As depicted, the
comb 140 may further comprise a connectingbar 148 provided at thedistal end 140a of thecomb 140. The connectingbar 148 may extend in the lateral direction of the comb. The connectingbar 148 may extend between two or more of thecomb teeth 142 to connect the teeth together. - The
hair collector 160 comprises abase wall 162, which is positioned adjacent to thebody 122 of thehair cutting appliance 120 when thehair cutting system 100 is assembled. Thehair collector 160 further comprises afront wall 164 opposite to thebase wall 162 and two ormore side walls 166 between thebase wall 162 and thefront wall 164. Thewalls hair collection chamber 168 for receiving hair cut by thehair cutting appliance 120. - An
opening 169 of thehair collection chamber 168 is defined byfree edges hair cutting system 100 is assembled, theopening 169 is arranged such that hair that is cut by the hair cutting appliance arrives at theopening 169 of the hair chamber. Theopening 169 may be arranged adjacent to thecutting blades 124. Theopening 169 may be defined on an opposite side of the cuttingplane 126 to thecomb surface 144. - Returning to
Figs. 3a and3b , thehair collector 160 further comprises one ormore coupling portions 170 configured to couple to thehair cutting appliance 120. Thehair collector 160 may comprise acoupling portion 170 provided on each lateral side of thehair collector 160. Thecoupling portions 170 may extend from theside walls 166 of thehair collector 160, e.g. on each lateral side of thehair collector 160. - The
coupling portions 128 of thehair cutting appliance 120 may be configured to couple with respective ones of thecoupling portions 170 of thehair collector 160. Thecoupling portions 170 of thehair collector 160 andcorresponding coupling portions 128 of thehair cutting appliance 120 may be couplable using a mechanical coupling method, such as clips, snap connectors, buttons or straps, or any other mechanical coupling method. - Additionally or alternatively, the
coupling portions 170 of thehair collector 160 andcorresponding coupling portions 128 of thehair cutting appliance 120 may be couplable using any other coupling method. For example, either or both of thecoupling portions 170 and the correspondingcoupling portions 128 may comprise magnets, and thehair collector 160 may be configured to couple to the hair cutting appliance using magnets. - As shown in
Figs. 4 and5 , because thehair collector 160 is coupled to thehair cutting appliance 120, theopening 169 of thehair collection chamber 168 remains in the same position relative to thecutting blades 124 of thehair cutting appliance 120 as the position of thecomb 140 relative to thehair cutting appliance 120 is varied, e.g. in order to adjust the hair cutting length. Thefree edge 162a of the base wall is substantially aligned with the distal end of the body of the hair cutting appliance, such that theopening 169 remains stationary relative to thecutting blades 124, e.g. adjacent to thecutting blades 124, as thecomb 140 moves relative to thehair cutting appliance 120. Furthermore, because thebase wall 162 of the hair collector extends up to the distal end of the hair cutting appliance, no gap is present between thebase wall 162 and theside walls 166 of thehair collector 160 adjacent to thecutting blades 124. - When the
hair collector 160 is coupled to thehair cutting appliance 120, a portion of thecomb 140 is arranged within thehair collection chamber 168. In the arrangement shown, thedistal end 140a of thecomb 140, e.g. the connectingbar 148 and part of the second portions of theteeth 142b, is arranged within thehair collection chamber 168. Thecomb 140 and thehair collector 160 are together configured such that thecomb 140 acts to restrict hairs from leaving thehair collection chamber 168. - The
opening 169 may be substantially covered by the comb, e.g. thecomb teeth 142, so cut hair passes though the comb in order to leave thehair collection chamber 168 through theopening 169. - As depicted in
Fig. 6 , a spacing S between thecomb teeth 142 may be selected in order to improve the retention of hairs within the hair collection chamber by thecomb teeth 142, e.g. by restricting the flow of hairs between thecomb teeth 142. As depicted, the spacing between the comb teeth may be less than or equal to 6.8mm, less than or equal to 6mm, less than or equal to 5mm, less than or equal to 4mm or less than or equal to mm. The spacing between the comb teeth may be greater than or equal to 1mm, greater than or equal to 2mm, or greater than or equal to 3mm. For example, the spacing between thecomb teeth 142 may be approximately 3.8mm. In other arrangements, the spacing between thecomb teeth 142 may be between approximately 6.8mm and approximately 1mm. - Returning to
Figs. 4 and5 , thefront wall 164 of thehair collector 160 extends from thebase wall 162 over and forwards of thedistal end 140a of thecomb 140, e.g. in the cutting direction C. Thefront wall 164 is shaped such that, as thecomb 140 moves relative to thehair cutting appliance 120, e.g. between the retracted and extended positions, aclearance 150 between thedistal end 140a of thecomb 140, e.g. the connectingbar 148, and thefront wall 164 of the hair collector remains substantially constant. - In other arrangements, the
front wall 164 may be shaped such that, as thecomb 140 moves relative to thehair cutting appliance 120, theclearance 150 varies, e.g. within a range of clearance values. A maximum clearance value of the range may be selected such that cut hairs are restricted from passing between thedistal end 140a of the comb and thefront wall 164 when theclearance 150 is at the maximum value. A minimum clearance value of the range may be selected in order to prevent the comb from interfering with thefront wall 164 as it moves. Alternatively, the minimum clearance value may be approximately 0mm, e.g. such that the distal end of the comb is touching thefront wall 164 when theclearance 150 is at the minimum value. - The
front wall 164 of thehair collector 160 may be shaped such that thefront wall 164 extends over and forwards of thedistal end 140a of thecomb 140 when thecomb 140 is in the retracted and extended positions, e.g. for all hair cutting lengths. In this way, thecomb 140 continues to cover theopening 169 of thehair collector 160 for all hair cutting lengths. - With reference to
Fig. 7 , in alternative arrangements, thefront wall 164 of the hair collector may comprise anaperture 700, when thehair collector 160 is coupled to thehair cutting appliance 120, thedistal end 140a of thecomb 140 may extend into or through theaperture 700. Hence, no gap may be present between thefront wall 164 and thecomb 140, e.g. in a direction perpendicular to the inside surface of thefront wall 164, though which hairs can pass out of thehair collection chamber 168. - In such arrangements, the length of the
comb teeth 142, e.g. thesecond portions 142b of the comb teeth, may be selected such that thecomb teeth 142 and/or connectingbar 148 extend into or through theaperture 700 when thecomb 140 is in the retracted and extended positions, e.g. for all hair cutting lengths. - With reference to
Fig. 8 , a rampedportion 162b of thebase wall 162 may be formed adjacent to thefree edge 162a of thebase wall 162. The rampedportion 162b may comprise a portion of thebase wall 162 over which the thickness of the base wall tapers from a wall thickness, away from thefree edge 162a, to an edge thickness at thefree edge 162a of the base wall. The edge thickness may be less than the wall thickness. - An
inside surface 162d of the rampedportion 162b of thebase wall 162, which may be referred to as a hair flow surface, may be substantially perpendicular to the cuttingplane 126 and/or thecomb surface 144. Arranging theinside surface 162d of the rampedportion 162b in this way improves the flow of hair into thehair collection chamber 168 over thebase wall 162. - The
inside surface 162e of awall portion 162c of the base wall on an opposite side of the rampedportion 162b to thefree edge 162a may be aligned with, e.g. substantially parallel with, thebody 122 of thehair cutting appliance 120, e.g. the outer surface of thebody 122 adjacent to thehair collector 160. - The
inside surface 162e of thewall portion 162c may by angled relative to theinside surface 162d of the rampedportion 162b. Thebase wall 162 may comprise acorner portion 162f between the rampedportion 162b and thewall portion 162c. The orientation of the inside surface of thebase wall 162 may change at thecorner portion 162f, e.g. from the orientation of the ramped portion insidesurface 162d to the orientation of the wall portion insidesurface 162e. As depicted, the orientation of the inside surface of thebase wall 162 may change discretely or abruptly at thecorner portion 162f. - The
inside surface 162e of thewall portion 162c may be at a lower angle relative to, e.g. less perpendicular to, thehair cutting plane 126 and/or the cutting direction C. By orienting the inside surfaces of the ramped portion and the wall portion in this way, hair flow into the chamber and retention of hair within the chamber may both be improved. - As depicted in
Fig. 9 , in addition to or as an alternative to thecorner portion 162f, thebase wall 162 may comprise acurved wall portion 162g. The orientation of the inside surface of thebase wall 162 may transition over thecurved wall portion 162g from being substantially perpendicular to the cuttingplane 126 and/or thecomb surface 144 at thefree edge 162a, to being substantially aligned with, e.g. parallel with, thebody 122 of thehair cutting appliance 120 away from thefree edge 162a. Thecurved wall portion 162g may be at least partially formed by the rampedportion 162b. Additionally or alternatively, thecurved wall portion 162g may be at least partially formed by thewall portion 162c. - With reference to
Fig. 10 , thebody 122 of thehair cutting appliance 120 may comprise arecess 122b. Therecess 122b may be configured to receive a portion of thehair collector 160 when the hair collector is coupled to thehair cutting appliance 120. For example, thebase wall 162 of thehair collector 160 may be received within therecess 122b. A depth of therecess 122b may be substantially equal to a thickness, e.g. a maximum thickness, of thebase wall 162. In this way, the inside surface of thebase wall 162 may be substantially aligned within theouter surface 122c of thebody 122 around therecess 122b. In other words, the inside surface of thebase wall 162 may be disposed where the outer surface of thebody 122 would be if therecess 122b was not provided in thebody 122. - With reference to
Fig. 11 , thehair collector 160 may further comprise ahair retaining wall 1000. Thehair retaining wall 1000 may extend from thebase wall 162 into thehair collection chamber 168. Thehair retaining wall 1000 is arranged between the closed end of thehair collection chamber 168 and theopening 169. Thehair retaining wall 1000 may extend across the lateral width of thehair collection chamber 168, e.g. between theside walls 166. Ahair gap 1002 may remain between thehair retaining wall 1000 and thefront wall 164 of thehair collector 160 to allow hairs to move past thehair retaining wall 1000 towards the closed end of thehair collection chamber 168. As depicted inFig. 11 , cut hairs may be retained by thewall 1000, e.g. between thewall 1000 and the closed end of thehair collection chamber 168. - As depicted, the
hair retaining wall 1000 may extend from thebase wall 162 in a direction with a component perpendicular to the cuttingplane 126, the cutting direction C and/or thecomb surface 144. For example, thehair retaining wall 1000 may extend away from thebase wall 162 in a direction substantially perpendicular to the cuttingplane 126. When thehair retaining wall 1000 is oriented in this way, thehair retaining wall 1000 may be particularly effective in retaining hairs within thehair collection chamber 168 when thehair cutting system 100 is being used on a substantially horizontal surface, such as the top of a person's head. - It will be appreciated by those skilled in the art that although the invention has been described by way of example, with reference to one or more exemplary examples, it is not limited to the disclosed examples and that alternative examples could be constructed without departing from the scope of the invention as defined by the appended claims.
