Description

FIELD OF TECHNOLOGY

The present invention relates to a hair cutting system, and in particular, but not exclusively, to a hair cutting system that improves the grip of cut hair.

BACKGROUND OF THE INVENTION

During hair cutting, the cut hair is usually allowed to fall out of the hair cutting device onto or around the person whose hair is being cut. This can be inconvenient for both the haircutter and the haircutter.

Cleaning hair after a haircut takes time and effort. In addition, cut hair that falls on the skin, such as the neck, face, back, forearms, and/or hands during clipping, can cause itching and irritation, which can make clipping uncomfortable.

It is especially desirable that the process of cutting hair is as comfortable as possible when cutting a child. Cut hair on a child's skin can cause itching and irritation, which will increase the difficulty of the clipper and possibly lead to poor clipping results.

Published patent application WO 2017/084897 A1 discloses a hair clipper system comprising a hair clipper, a spacer comb and a hair collection container, the hair collection container being positionable between the comb and the clipper.

Published patent application WO 2017/021202 A1 discloses a hair clipper system comprising a hair clipper, a spacer comb and a hair collection container, the hair collection container being attachable to the comb. When attached, the hair collection container extends between the comb and the clipper and also behind the comb.

Published patent application FR 2 809 049 A1 discloses a hair cutting device comprising an air supply device for blowing cut hair particles into a receiving container at some distance from the device.

DISCLOSURE OF THE INVENTION

According to an aspect of the present invention, there is provided a hair cutting system comprising: a hair cutting device comprising one or more pairs of hair cutting blades; a comb disposed in front of the cutting blades, for example, when viewed in a direction of travel (cutting direction) of the hair cutting device, and configured to guide hair towards the cutting blades; and a hair collecting device comprising a hair chamber configured to receive hair cut by the hair cutting device and a connecting part configured to connect the hair collecting device to the hair cutting device.

The comb and the hair collecting device are designed such that when the hair cutting system is assembled, a part of the comb, such as the distal part of the comb, is located inside the hair chamber.

The hair chamber wall, e.g. the front wall of the hair chamber, may extend, for example, from the hair cutting device in front, for example in the direction of cutting, of the distal end of the comb, for example, the end of the comb furthest from the hair cutting device along the comb, and above it .

The wall of the hair chamber, for example the front wall of the hair chamber, may comprise an opening. The comb may be configured such that the distal end of the comb extends into or through the opening, for example when the hair cutting system is assembled.

The opening of the hair chamber to receive the hair may be substantially closed by the comb or the cutting blades and the comb, for example such that the hair leaving the hair chamber passes through the cutting blades or the comb.

The comb may include a plurality of comb teeth. The teeth of the ridge may be spaced laterally across the ridge, such as perpendicular to the shear direction. The distance between the teeth of the comb may be about 3.8 mm, for example, to limit the exit of hair from the hair chamber between the teeth of the comb. The distance between the teeth of the comb may be less than or equal to 6.8 mm, less than or equal to 6 mm, less than or equal to 5 mm, less than or equal to 4 mm, or less than or equal to 3 mm. The distance between the teeth of the comb may be greater than or equal to 1 mm, greater than or equal to 2 mm, or greater than or equal to 3 mm.

The spacing between the teeth of the comb may be from about 3.8 mm to about 6.8 mm, such as less than or equal to 6.8 mm and greater than or equal to 3.8 mm. In some embodiments, the distance between the teeth of the comb may be from about 1 mm to 6.8 mm, such as greater than or equal to 1 mm and less than or equal to 6.8 mm. In an alternative embodiment, the distance between the teeth of the comb may be from about 1 mm to about 3.8 mm, such as greater than or equal to 1 mm and less than or equal to 3.8 mm.

The hair collecting device may include a base wall configured to engage or align with the surface of the body of the hair cutting device when the hair collecting device is connected to the hair cutting device. The free edge of the base wall may at least partially define the opening of the hair chamber.

The hair cutting device may include a recess configured to receive at least a portion of the base wall of the hair collecting device.

The interior wall surface of the base may be oriented substantially perpendicular to the cutting plane of the hair of the hair cutting device, such as the plane where the hair is cut by the cutting blades of the hair cutting device, at a free edge, for example at the opening of the hair collecting device. The inner wall surface of the base may be substantially aligned with the surface of the body of the hair cutting device at a location away from the free edge. The base wall may include an angular portion in which the orientation of the base wall inner surface changes.

The wall of the base may contain a curved section of the wall. The orientation of the base wall, such as the inner surface of the base wall, can transition through the curved wall portion from substantially perpendicular to the hair cutting plane at the edge to substantially aligned with the surface of the hair cutting device body away from the free edge.

The wall of the base may include a sloped portion extending from the free edge into, for example, a hair chamber. The sloped portion may define a hair flow surface substantially perpendicular to the hair cutting plane of the cutting blades. The wall thickness of the base can vary along the sloped section from the edge thickness at the free edge to the wall thickness away from the free edge. The edge thickness may be less than the wall thickness.

The base wall may comprise a wall section on the side of the sloped section opposite the free edge. The wall portion may be substantially aligned with or cooperating with the surface of the body of the hair cutting device.

The wall section may be located at a smaller angle relative to the cutting plane of the hair, for example less perpendicular to the cutting plane of the hair, compared to the flow surface of the hair.

In other words, the wall of the base of the hair collector may include a first slope adjacent to the free edge and a second slope on the side of the first slope opposite the edge, wherein the first slope, such as the inner surface of the first slope, may be sloped at a large angle with respect to the hair cutting plane of the hair cutting device than the second inclined portion. In other words, the first sloping portion may be more perpendicular to the cutting plane of the hair than the second sloping portion.

The cutting blades of the hair cutting device may extend from the distal end of the body of the hair cutting device. The free edge of the base wall may be substantially aligned with the distal end of the body of the hair cutting device, for example, near the cutting blades. Therefore, the opening of the hair chamber can be substantially aligned with the distal end of the body of the hair cutting device. The hair chamber may be closed on three or more sides of the chamber at the opening.

The comb may form a comb surface that is pressed against the user's skin when using the hair cutting system. The surface of the comb can be selectively offset from the cutting blades by the cutting length of the hair, so that the length of the hair cut by the hair cutting system is determined according to the cutting length of the hair.

The comb may be movable relative to the cutting blades, for example in a direction perpendicular to the cutting direction of the hair cutting device, to change the length of the cut by the hair cutting system. The comb and the hair collector may be configured such that the gap between the distal end of the comb and the inner surface of the hair chamber is substantially constant as the comb is moved. Alternatively, the gap between the distal end of the comb and the inner surface of the hair chamber may vary, for example, within a range of gap values as the comb is moved.

The hair collecting device may further comprise a hair retaining wall between the 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 from the base wall in a direction substantially perpendicular to the hair cutting plane of the cutting blades or the cutting direction of the hair cutting device.

IMPLEMENTATION OF THE INVENTION

As shown in FIG. 1 and 2, the previously proposed hair cutting system 2 comprises a hair cutting device 40, a comb 60 configured to guide hair to be cut to cutting blades 42 of the hair cutting device 40, and a hair collecting device 80 configured to receive and storing the hair cut by the hair cutting device 40 .

The hair cutting device 40 includes a body 44 containing a gripping portion 46 configured to be held by a user when using the hair cutting system. The cutting blades 42 may protrude from the distal end 44a of the housing 44.

As shown in FIG. 2, the hair cutting system 2 is adjustable so that the position of the surface 62 of the comb 60 can be adjusted relative to the body 44 of the hair cutting device 40 and the cutting blades 42.

In use, the comb surface 62 is pressed against the skin of the person whose hair is being cut, and the hair cutting system 2 is moved over the person's skin in the cutting direction C to cut the person's hair.

The length of the hair cut by the hair cutting system 2 is controlled by adjusting the distance between the surface 62 of the comb 60 and the cutting blades 42 of the hair cutting device 40 .

As shown in FIG. 1 and 2, the hair collector 80 is connected to the comb 60 such that the hair collector 80 moves with the comb 60 as the position of the comb surface 62 is adjusted.

The hair collection device 80 includes a plurality of walls 82, 84, 86 which form a hair collection chamber 88 for receiving cut hair. In particular, the hair collector 80 includes a base wall 82 that is adjacent to the body of the hair cutter, a front wall 84 opposite the base wall 82, and two or more side walls 86 between the base wall 82 and the front wall. 84. The free edges 82a, 84a, 86a of the walls 82, 84, 86 of the hair collection device form an opening 89 of the hair collection chamber 88.

As shown, when the hair collection device 80 is connected to the comb 60, a part of the comb 60 is positioned over the opening 89 of the hair collection chamber 88 and restricts the exit of hair from the hair collection chamber 88. Because the hair collector 80 is connected to the comb and moves with the comb 60, the comb 60 continues to restrict the exit of hair from the hair collection chamber 88 when the hair cutting length is adjusted.

As shown in FIG. 1, the free edge 82a of the base wall 82, which partially forms the opening 89 of the hair collection chamber 88, is offset from the distal end 44a of the hair cutter body 44, such as the comb surface 62, so that the base wall 82 does not interfere with the cutting blades 42 of the hair cutter. hair cutting when the comb 60 is moved away from the hair cutting device 40 to adjust the hair cutting length, for example, as shown in FIG. 2.

Since the free edge 82a of the base wall is offset from the distal end 44a of the body 44, a gap 90 can be formed between the body 44 of the hair cutting device 40 and the side walls 86 of the hair collecting device 80, which can allow hair to fall out of the hair collection chamber 88, in particular, when the distance between the ridge surface 62 and the cutting blades 42 is minimal, and the distance between the cutting blades 42 and the base wall free edge 82a is maximum, as shown in FIG. one.

As shown in FIG. 3a and 3b, a hair cutting system 100 according to embodiments of the present invention comprises a hair cutting device 120, a comb 140, and a hair collecting device 160.

The hair cutting device 120 may be similar to the hair cutting device 40, and the features described above with reference to the hair cutting device 40 can equally be applied to the hair cutting device 120.

The hair cutting device 120 includes a body 122 containing a gripping portion 123 and cutting blades 124 for cutting hair. As shown, the cutting blades 124 may protrude from the distal end 122a of the housing 122.

In addition, the hair cutting device 120 may include one or more connecting parts 128 configured to allow the hair collecting device 160 to be connected to the hair cutting device 120, as described below.

In the embodiment shown, the cutting blades 124 comprise a pair of blades including a movable blade and a fixed blade (which may be referred to as a comb or guard blade). Each of the movable and fixed blades contains a plurality of teeth, and the teeth of the fixed blade correspond to the teeth of the movable blade. The movable blade is driven by the motor of the hair cutter to reciprocate, oscillate or rotate relative to the fixed blade and open and close gaps between respective teeth of the movable and fixed blades. When the gaps are open, the hair can be taken between the teeth and then the hair is cut off when the gaps are closed. In some designs, the teeth of both the movable and fixed blades may have sharpened edges. Alternatively, the teeth of the movable or fixed blade may not be sharpened, and the hair may be cut by the action of the sharpened blade over the blunt edge of the unsharpened blade. The cutting blades 124 are configured to cut hair in a cutting plane 126 defined by the cutting blades. In addition, the present invention can be applied to hair cutting devices containing various types of cutting blades or other cutting elements for cutting human hair.

The ridge 140 includes a plurality of ridge teeth 142 spaced laterally across the ridge 140, such as in a direction parallel to the shear plane 126 and perpendicular to the shear direction C. The teeth 142 of the comb are shaped and positioned so as to lift the hair away from the skin and guide the hair towards the cutting blades 124 when the hair cutting system 100 is moved in the cutting direction C, for example, so that the hair can more easily enter the gaps between the moving and fixed blades.

The comb 140 defines a comb surface 144 that adheres to the skin of a person whose hair is being cut when the hair cutting system 100 is used. As described above, the length that the hair is cut with the hair cutting system is determined according to the distance between the comb surface 144 and the cutting blades 124.

The comb 140 includes a connecting portion 146 configured to movably connect the comb 140 to the hair cutter 120 to allow the comb 140 to move relative to the hair cutter to adjust the length of the hair cut. The comb 140 may be movable relative to the hair cutter 120 between a retracted position, as shown in FIG. 4 and the extended position as shown in FIG. 5.

The teeth 142 of the comb include first portions 142a that extend from the connecting portion 146 in the cutting direction C. The ridge surface 144 may be at least partially formed by the first sections 142a of the teeth of the ridge, such as the lower surfaces of the first sections 142a. The ridge teeth 142 further comprise second sections 142b that extend from respective first ridge teeth sections 142a to the distal end 140a of the ridge 140. As shown, the second ridge teeth sections 142b may extend in a direction with a component perpendicular to the ridge surface 144, such as away from the surface. comb. For example, the second portions 142b of the teeth of the comb may extend in a direction substantially perpendicular to the surface 144 of the comb.

The second comb tooth portions 142b may provide support for the hair that has been lifted from the skin as the hair is guided towards the cutting blades 124. In addition, the second comb tooth portions 142b may limit hair loss from the hair collector 160, as described below.

As shown, the ridge 140 may further include a connecting rod 148 located at the distal end 140a of the ridge 140. The connecting rod 148 may extend in the lateral direction of the ridge. The connecting rod 148 may extend between two or more teeth 142 of the comb to connect the teeth to each other.

The hair collecting device 160 includes a base wall 162 that is located adjacent to the body 122 of the hair cutting device 120 when the hair cutting system 100 is assembled. The hair collection device 160 further comprises a front wall 164 opposite the base wall 162 and two or more side walls 166 between the base wall 162 and the front wall 164. The walls 162, 164, 166 together form a hair collection chamber 168 configured to receive hair cut by the hair cutting device 120 .

The free edges 162a, 164a, 166a of the walls of the hair collecting device form an opening 169 of the hair collecting chamber 168. When the hair cutting system 100 is assembled, the opening 169 is positioned such that the hair cut by the hair cutting device enters the opening 169 of the hair chamber. Hole 169 may be located adjacent to the cutting blades 124. Hole 169 may be formed on the side of the cutting plane 126 opposite the ridge surface 144.

As shown in FIG. 3a and 3b, the hair-collector 160 further comprises one or more connecting portions 170 configured to be connected to the hair-cutting device 120. The hair collector 160 may include a connecting portion 170 located on each side of the hair collector 160 . Connecting portions 170 may protrude from the side walls 166 of the hair collector 160, such as on each side of the hair collector 160 .

The connecting parts 128 of the hair cutting device 120 may be configured to be connected to the corresponding connecting parts 170 of the hair collecting device 160 . The connecting parts 170 of the hair collector 160 and the corresponding connecting parts 128 of the hair cutting device 120 may be configured to be connected using a mechanical connection method such as clips, snap connectors, buttons or straps, or any other mechanical connection method.

In a further or alternative embodiment, the connecting parts 170 of the hair collector 160 and the corresponding connecting parts 128 of the hair cutting device 120 may be configured to be connected using any other connection method. For example, one or all of the connecting parts 170 and the corresponding connecting parts 128 may contain magnets, and the hair collector 160 can be configured to be connected to the hair cutting device using magnets.

As shown in FIG. 4 and 5, since the hair collecting device 160 is connected to the hair cutting device 120, the opening 169 of the hair collecting chamber 168 remains in the same position relative to the cutting blades 124 of the hair cutting device 120, since the position of the comb 140 relative to the device 120 for cutting hair varies, for example, to adjust the length of hair cutting. The free edge 162a of the base wall is substantially aligned with the distal end of the body of the hair cutter such that the opening 169 remains stationary relative to the cutting blades 124, such as adjacent to the cutting blades 124, as the comb 140 is moved relative to the hair cutter 120. In addition, since the base wall 162 of the hair collector extends to the distal end of the hair cutter, there is no gap between the base wall 162 and the side walls 166 of the hair collector 160 adjacent to the cutting blades 124.

When the hair collecting device 160 is connected to the hair cutting device 120, a part of the comb 140 is located inside the hair collecting chamber 168. In the illustrated embodiment, the distal end 140a of the comb 140, such as the connecting rod 148 and part of the second portions 142b of the teeth, are located inside the chamber 168 for collecting hair. The comb 140 and the hair collection device 160 are formed together such that the comb 140 restricts the exit of hair from the hair collection chamber 168 .

The opening 169 may be substantially covered by a comb, such as the teeth 142 of the comb, so that the cut hair passes through the comb to exit the hair collection chamber 168 through the opening 169.

As shown in FIG. 6, the distance S between the comb teeth 142 can be selected to improve the retention of hair within the hair collection chamber by the comb teeth 142, for example, by restricting the flow of hair between the comb teeth 142. As shown, the tooth spacing of the comb may be less than or equal to 6.8 mm, less than or equal to 6 mm, less than or equal to 5 mm, less than or equal to 4 mm, or less than or equal to mm. The distance between the teeth of the comb may be greater than or equal to 1 mm, greater than or equal to 2 mm, or greater than or equal to 3 mm. For example, the distance between the teeth 142 of the comb may be approximately 3.8 mm. In other embodiments, the distance between the teeth 142 of the comb may be from about 6.8 mm to about 1 mm.

As shown in FIG. 4 and 5, the front wall 164 of the hair collector 160 extends from the base wall 162 over and in front of the distal end 140a of the comb 140, such as in the cutting direction C. The front wall 164 is shaped such that when the comb 140 is moved relative to the hair cutter 120, such as between the retracted and extended positions, the gap 150 between the distal end 140a of the comb 140, such as the connecting rod 148, and the front wall 164 of the hair collector remains essentially permanent.

In other embodiments, front wall 164 may be shaped such that as comb 140 moves relative to hair clipper 120, gap 150 changes, such as within a range of gap values. The maximum value of the range gap may be selected so as to limit the passage of the cut hair between the distal end 140a of the comb and the front wall 164 when the gap 150 is set to the maximum value. The minimum range gap value can be chosen to prevent the ridge from colliding with the front wall 164 during movement. In an alternative embodiment, the minimum gap value may be approximately 0 mm, such that the distal end of the ridge touches front wall 164 when gap 150 is set to its minimum value, for example.

The front wall 164 of the hair collector 160 may be shaped such that the front wall 164 extends ahead of and over the distal end 140a of the comb 140 when the comb 140 is in the retracted and extended positions, for example, for any cut length. Thus, the comb 140 continues to cover the opening 169 of the hair collector 160 for any cut length.

As shown in FIG. 7, in alternative embodiments, the front wall 164 of the hair collector may include an opening 700 into or through which the distal end 140a of the comb 140 may pass when the hair collector 160 is connected to the hair cutter 120. Therefore, there may be no gap between the front wall 164 and the comb 140, for example in a direction perpendicular to the inner surface of the front wall 164, through which the hair can exit the hair collection chamber 168.

In such embodiments, the length of the comb teeth 142, such as the second portions of the comb teeth 142b, may be chosen such that the comb teeth 142 and/or connecting rod 148 extend into or through opening 700 when the comb 140 is in the retracted and extended positions, for example for any cutting length.

As shown in FIG. 8, the sloped portion 162b of the base wall 162 may be formed adjacent to the free edge 162a of the base wall 162. The sloped portion 162b may include a portion of the base wall 162 where the base wall tapers from the wall thickness away from the free edge 162a to the edge thickness at the free edge 162a of the base wall. The edge thickness may be less than the wall thickness.

The inner surface 162d of the sloped portion 162b of the base wall 162, which may be referred to as the hair flow surface, may be substantially perpendicular to the cutting plane 126 and/or the comb surface 144. Positioning the inner surface 162d of the sloping portion 162b thus improves the flow of hair into the hair collection chamber 168 along the base wall 162 .

The inner surface 162e of the base wall portion 162c on the side of the sloped portion 162b opposite the free edge 162a may be aligned, e.g. substantially parallel, with the body 122 of the hair cutting device 120, e.g. hair collection.

The inner surface 162e of the wall section 162c may be angled relative to the inner surface 162d of the ramp 162b. The base wall 162 may include an angled portion 162f between the sloped portion 162b and the wall portion 162c. The orientation of the inner surface of the wall 162 of the base can change in the corner section 162f, for example, from the orientation of the inner surface 162d of the inclined section to the orientation of the inner surface 162e of the wall section. As shown, the orientation of the inner surface of the base wall 162 may change discretely or abruptly at the corner portion 162f.

The inner surface 162e of the wall portion 162c may be located at a smaller angle, such as less perpendicular to the hair cutting plane 126 and/or the cutting direction C. By orienting the inner surfaces of the slope portion and the wall portion in this way, the flow of hair into the chamber and the retention of hair within the chamber can be improved.

As shown in FIG. 9, in addition to or alternatively to the corner portion 162f, the base wall 162 may comprise a curved wall portion 162g. The orientation of the inner surface of the base wall 162 can transition through the curved wall portion 162g from being substantially perpendicular to the cutting plane 126 and/or the ridge surface 144 at the free edge 162a to being substantially aligned, such as parallel, with the body 122 of the hair cutting device 120 away from free edge 162a. The curved wall section 162g may be at least partially formed by the sloped section 162b. In a further or alternative embodiment, the curved wall portion 162g may be at least partially formed by the wall portion 162c.

As shown in FIG. 10, the body 122 of the hair cutter 120 may include a recess 122b. The recess 122b may be configured to receive a portion of the hair picker 160 when the hair picker is connected to the hair cutter 120. For example, the base wall 162 of the hair collector 160 may fit into the recess 122b. The depth of recess 122b may be substantially equal to the thickness, such as the maximum thickness, of base wall 162. Thus, the inner surface of the base wall 162 can be substantially aligned within the outer surface 122c of the housing 122 around the recess 122b. In other words, the inner surface of the base wall 162 may be located where the outer surface of the housing 122 would be if the recess 122b were not made in the housing 122.

As shown in FIG. 11, the hair collector 160 may further comprise a hair retaining wall 1000. The hair holding wall 1000 may extend from the base wall 162 to the hair collection chamber 168 . The hair containment wall 1000 is located between the closed end of the hair collection chamber 168 and the opening 169. The hair containment wall 1000 may extend across the width of the hair collection chamber 168, such as between the side walls 166. Between the hair containment wall 1000 and the front wall 164 of the device 160 for collecting hair, a gap 1002 may remain to allow passage of hair past the wall 1000 for holding hair to the closed end of the chamber 168 for collecting hair. As shown in FIG. 11, the cut hair may be held by the wall 1000, for example between the wall 1000 and the closed end of the hair collection chamber 168.

As shown, the hair retaining wall 1000 may extend from the base wall 162 in a direction with a component perpendicular to the cutting plane 126, the cutting direction C, and/or the comb surface 144. For example, the hair retaining wall 1000 may extend from the base wall 162 in a direction substantially perpendicular to the cutting plane 126 . When the hair containment wall 1000 is oriented in this manner, it can be particularly effective in retaining the hair within the hair collection chamber 168 when using the hair cutting system 100 on a substantially horizontal surface, such as the top of a person's head.

Those skilled in the art will appreciate that while the invention has been described by way of example with reference to one or more illustrative examples, it is not limited to the disclosed examples, and alternative examples may be provided within the scope of the invention as defined by the appended claims.
