Definitions

  • the present invention relates to a hair-cutting razor for partially cutting hair, and a replaceable hair-cutting razor applied to the hair-cutting razor.
  • Hair-cutting razors are used widely for creating attractive hairstyles.
  • a blade body 32 of a razor 30 is structured such that a blade edge 34 is covered discontinuously by semicircular protrusions 36 protruding from the blade edge 34, and thus an exposed blade edge 34a and a covered blade edge 34b are provided alternately.
  • a groove 38 for limiting the amount of combing during hair cutting is provided between adjacent pairs of the protrusions 36, 36 (see Figs. 16 and 17 ).
  • the exposed blade edges 34a face the hair at a right angle (in the shape of a cross), similarly to known razors of this type (see Figs. 18 and 19 ).
  • the exposed blade edges 34a face the hair H at a right angle, the hair H may be cut excessively.
  • the blade edge 34a of the blade body 32 moves in a right-angled direction to the hair H, as shown in the drawings, and hence the hair H can be cut reliably.
  • the cutting function improves as the angle of incline of the blade edge 34a relative to the hair H shifts from an acute angle toward a right angle, and as the cutting function improves, the hair H may be cut excessively, leading to a difference between the hair in the uncut portion and the hair in the cut portion. As a result, an unbalanced haircut may be created.
  • the angle of incline of the blade edge 34a may be varied, thereby suppressing excessive hair cutting, but an operation to vary the angle of incline is not always easy.
  • the razor 30 When the razor 30 is used to cut the hair H on one's own head, particularly the hair H on the rear surface of the head which is difficult to see, it is necessary to rely on a "knack", or in other words intuition, and therefore the hair H may be cut excessively, or on the other hand, the amount of hair that is cut may be insufficient. Hence, the difficult of avoiding an unbalanced haircut remains.
  • US 6,161,288 A describes a four blade bi-directional razor structure with a flexible guard system.
  • the razor is preferably formed of any suitable molded plastic material to provide a head and an integral hand grip or handle.
  • the hand grip may have an upper portion which is molded integrally with the head and a lower angled and hand-holding portion.
  • the head is provided with a first pair of razor blades and an oppositely, angularly extending, second pair of razor blades.
  • the blades are each formed of a narrow, single sharpened edge razor blade grip.
  • Each blade strip has an inner portion, which is embedded within the head, and an outer, sharpened edge portion, which extends outwardly from the head for cutting whisker. The sharpened edges are arranged so that edges cut in one direction while edges cut in the opposite direction.
  • the other pair when one pair of edges cut, the other pair merely drags or rides upon the skin and guides the edges that cut.
  • the two opposing pairs of blades are close to each other, and extent outwardly at an acute angle relative to the working plane of the head of the razor.
  • This acute angle may be any suitable value, such as in the range of about 5° to about 40°, with angles in the range of 15° to 35° being presently preferred.
  • the razor is applied against the user's skin and is moved back and forth.
  • the sharp edges of the one pair of blades engage the skin and cut the hair in the upward direction.
  • the user may move the handle downwardly so that the sharp edges of the second pair of razor blades cut the hair without lifting the razor head away from the skin.
  • US 2,610,393 A describes a hair-cutting and collecting device.
  • the hair collecting receptacle is composed of two concavo-convexed walls.
  • a forward side of the receptacle is formed with an entrance opening for cut hair, or stated differently, the forward edge of the wall is spaced sufficiently from the forward edge of the wall to define an entrance opening for cut hair.
  • the forward edge of the wall is formed with a plurality of transverse inwardly tapering slots to form comb teeth between adjacent slots and a toothed edge for the wall.
  • a pair of relatively inclined razor blades are held clamped against the inner face of the wall by an elongated clamping plate whose ends are secured to the wall.
  • the receptacle is grasped by one hand of a user and passed through the user's hair with the toothed edge of the wall functioning as a comb to lift the hair and the blades, will cut the hair whereupon the cut hair will enter the receptacle.
  • the hair grooming device comprises a support body having an elongated head and an elongated shaped handle projecting therefrom.
  • the head is shaped as a rectangular solid having opposed broad top and bottom faces, opposed elongated side surfaces, and opposed end surface.
  • a handle projects from the end surface.
  • a rectangular array of hairbrush bristle members are rooted into top face and project perpendicularly therefrom. Bristle members are distributed generally throughout top face and are tapered in length transversely of the head so that the longest bristles members are in the center of head as viewed from the end of the head.
  • Within a pocket there is carried a double-edged razor blade cartridge.
  • the cartridge includes an elongated rectangular carrier plate from opposite sides of which project longitudinally elongated razor blade edges in opposite directions.
  • the blade edges project from top and bottom faces, respectively.
  • blade cartridges are adapted to slide downward in pockets to project the blades at adjustable heights alongside comb teeth.
  • hair is directed serially through the edges of the three blades carried in pockets to make various new cutting techniques possible by setting each blade at a different height.
  • JP 60-103402 U describes a comb being provided with an replaceable hair-cutting razor.
  • a replaceable hair-cutting razor with a blade is adapted to be inserted in a distal portion of a comb basis material to be located next to comb teeth being aligned in the length direction of the comb basis material.
  • the cutting edge of the blade of the hair-cutting razor stands upright on the comb basis material and in line with the comb teeth.
  • the cutting edge is hereby facing in a right-angled direction to the upright direction of the blade and oriented in the length direction of the line of comb teeth each standing upright on the comb basis material.
  • An object of the present invention is to solve the problems of the background art described above by providing a hair-cutting razor which cuts hair in a balanced fashion without cutting the hair excessively or insufficiently, and replace hair-cutting razor which is applied to the hair-cutting razor.

  • Fig. 1 is a preferred example of a case in which hair on the rear scalp surface of a head T is cut from the right side to the neck side, and hence is for right-handed use, as will be described in more detail below.
  • the cutting edges 12a are oriented toward the right side of the drawing, i.e. in symmetry with the example shown in Fig. 1 , and hence this example is for left-handed use.
  • These examples are basically constituted such that the blades 12 comprising the cutting edges 12a stand upright on the hair-cutting razor host material 14, and the cutting edges 12a are facing in a right-angled direction to the upstanding direction of the blades 12.

  • the blade 12 is made of metal, and when used to cut hair on the scalp, care is required to reduce danger.
  • the blade 12 typically takes a thin plate form and is therefore undeniably lacking in strength. Hence, by inserting the blade 12 into the blade cover 12b, an increase in the strength of the blade 12 is achieved.
  • the material qualities thereof may help to prevent injury to the scalp during use of the razor 10.
  • three protrusions 12c are provided on the cover 12b of the blade 12 at fixed intervals so as to protrude slightly beyond the line of extension of the cutting edge 12a of the blade 12 in a right-angled direction to the line of extension of the cutting edge 12a.
  • protrusions 12c By means of these protrusions 12c, the strength of the cover 12b can be increased, and by providing the protrusions 12c at fixed intervals, hair H that is led between adjacent blades 12 during cutting can be separated by the protrusions 12c.
  • the hair H does not become concentrated in a local portion of the cutting edge 12a, and therefore concentrated stress is not applied to the cutting edge 12a.
  • the hair H can be cut smoothly, and no load is placed on the cutting edge 12a.
  • a pin-shaped object standing upright beside the cutting edge 12a of the blade 12 is a control member 18 for protecting human fingers and so on during handling of the razor 10.
  • the control member 18 is preferably positioned approximately 5mm, for example, to the left and right of a center line of the cutting edge 12a so as not to damage the hair H that is led to the cutting edge 12a during cutting of the hair H.
  • the blade 12 side of the hair-cutting razor 10 is oriented toward the hair H and generally moved along the scalp T from the crown of the head to the neck side.
  • the cutting edge 12a of the blade 12 does not contact the hair H in a right-angled direction, as in the background art, and instead, the cutting edge 12a moves along the hair H so as to stroke the hair H.
  • the cutting edge 12a of the blade 12 faces the neck side of the body so as to follow the length direction of the hair H, and as the razor 10 moves, the hair H is gradually cut in the direction of an arrow Y in Figs. 4 and 5 along the hair H and so as to stroke the hair H.
  • the cutting edge 12a of the blade 12 moves in an acute angle direction relative to the hair H, unlike the blade body 32 of the background art, which moves in a right-angled direction to the hair H.
  • the cutting edge 12a which moves in an acute angle direction, then moves gradually from the hair H positioned on the top of the head toward the hair H positioned on the neck side, and since the movement direction of the cutting edge 12a is an acute angle direction nearly parallel to the hair H in this case, the cutting edge 12a never moves in a right-angled direction relative to the hair H.
  • the hair H can be trimmed such that tapered hair H is obtained, in contrast to the cutting edge 34a of the background art which moves in a right-angled direction to the hair H, and hence an attractive hairstyle can be obtained (see Fig. 6 ).
  • all of the cutting edges 12a of the blades 12 face the same direction, but in this example, as shown in the drawing, the cutting edges 12a of the six blades 12 are disposed such that adjacent cutting edges 12a are oriented in different directions.

  • the pin-shaped control member 18 is provided beside the cutting edge 12a of the blade 12, as in the first embodiment.
  • This example is advantaged in that the cutting edges 12a of the blades 12 are provided in different directions to each other, and therefore the razor 10 can be used with both the left and right [hands], as is evident from the above description of the first embodiment.
  • the blades 12 are not inclined, but provided in parallel, whereas in this embodiment, the cutting edges 12a of the blades 12 are oriented in the same direction and divided into those which are inclined to the upper right of the drawing about a reference line L, and those which are inclined to the upper left of the drawing about the reference line L (see Figs. 8 and 9 ).
  • this embodiment is applicable for use with both the left and right hands, similarly to the first embodiment'.
  • the angle of the cutting edge 12a relative to the hair H during use of the hair-cutting razor 10 differs considerably according to the preferences of the user, the combing location of the hair H, and the cutting location of the hair H.
  • the angle relative to the hair H may also differ according to differences in the dominant arm.
  • the angle of incline of the cutting edge 12a of the blade 12 is preferably within a range of 10 to 80 degrees, and more preferably approximately 60 degrees, toward the upper left of the drawing relative to the reference line L of the hair-cutting razor host material 14 (see Fig. 8 ).

  • the replaceable hair-cutting razor 20 differs from the hair-cutting razor 10, in which the blades 12 are attached non-detachably to the hair-cutting razor host material 14, merely in that instead of attaching the blades 12 to the hair-cutting razor host material 14, the blades 12 and control members 18 are provided on a razor host material 22. Accordingly, constitutions shared with the hair-cutting razor 10 are incorporated herein, and description thereof has been omitted.
  • the constitution of the razor host material 22 to and from which the hair-cutting razor 10 can be attached and detached will also be described (see Figs. 13 , 14 , 15 ).
  • the blades 12 stand upright on the razor host material 22, and the control members 18 stand upright adjacent to the blades 12 (see Figs. 13 , 14 ).
  • five blades 12 are provided, but as in the hair-cutting razor 10 described above, the number of blades may be set freely in accordance with requirements.
  • the hair-cutting razor 10 is provided detachably in a fitting hole 24 formed in the razor host material 22, and hence the blade host material 22 is provided in accordance with the shape of the fitting hole 24 (see Figs. 13 to 15 ).
  • one side of the host material 22 is formed with a wave-shaped undulating surface 22a
  • one side of the fitting hole 24 of the hair-cutting razor host material 14 is formed with a wave-shaped undulating surface which corresponds to the wave-shaped undulating surface 22a on one side of the host material 22 (see Fig. 14 ).
  • stoppers 22b, 22b are formed on each side of the host material 22 in the lengthwise direction.
  • engaging stepped portions 22e, 22e corresponding to the stoppers 22b, 22b are formed on the two sides of the opening of the fitting hole 24 on the surface side of the hair-cutting razor host material 14 (see Fig. 15 ).
  • the blade host material 22 is fitted into the fitting hole 24 of the hair-cutting razor host material 14.
  • the wave-shaped undulating surface 22a of the host material 22 is fitted into the wave-shaped undulating surface of the fitting hole 24 in the hair-cutting razor host material 14, and the stoppers 22b, 22b provided on the host material 22 are supported by the engaging stepped portions 22e, 22e of the hair-cutting razor host material 14.
  • the replaceable hair-cutting razor 20 can be attached securely and unmovingly to the hair-cutting razor host material 14.
  • a grip 22c is provided on the host material 22 to assist removal of the replaceable hair-cutting razor 20 (see Fig. 13 ).
  • the hair-cutting razor 10 in which the blades 12 comprising the cutting edges 12a stand upright on the hair-cutting razor host material 14, can be obtained (see Figs. 13 , 14 ).
  • the actions and effects of the hair-cutting razor attached with the replaceable hair-cutting razor 20 are identical to the actions and effects of the hair-cutting razor 10 described above.
  • the replaceable hair-cutting razor 20 can be removed from the hair-cutting razor host material 14 and a new replaceable hair-cutting razor 20 can be attached. As a result, a hair-cutting razor exhibiting an excellent cutting function can be obtained easily.
  • the hair-cutting razor 10 of the present invention is provided integrally with the bristles of a hairbrush, and in particular, the density of the bristles differs on the front side and rear side of the cutting edges.
  • the side on which the bristle density is to be relatively increased i.e. either the front or the rear of the cutting edges of the hair-cutting razor 10, may be selected arbitrarily in accordance with the purpose of the hair-cutting razor 10. Note, however, that in order to obtain an actual sense of the relative difference in the bristle density during hair cutting and brushing, the relative difference in the bristle density should be at least 5%. Preferably, the bristle density difference should be set between 10 and 30%.
  • the bristle density on the front side of the cutting edges is preferably set to be relatively lower than the bristle density on the rear side in order to perform hair cutting and brushing efficiently.
  • the reason for this is that before cutting the hair, the hair need only be arranged roughly at the cutting edges, whereas after the hair is cut, the hairstyle is preferably finished through fine brushing.
  • an appropriate and safe hair-cutting operation can be performed easily and speedily, enabling even a person without specialist skills to perform a desired hair-cutting operation reliably.
  • a person possessing specialist skills can perform a fine hair-cutting operation efficiently without the complicated work required conventionally, and hence the present invention may bring much new demand to the industry. Accordingly, the present invention is considered to possess excellent industrial applicability.
