Description

Barber {HAIR CLIPPER}

The present invention relates to a hair clipper, and more particularly to a hair clipper having a clipping height adjustment function.

Conventionally, electric hair clippers configured to cut human hair have been provided by using a comb-shaped stationary blade and a comb-shaped movable blade reciprocating with respect to the stationary blade. An electric hair clipper is a hair clipper configured to change the scissor height through the attachment of a specific attachment to adjust the scissor height, and a blade end direction that crosses the reciprocating direction and the blade thickness direction to change the relative position of the fixed blade and the movable blade. And a hair clipper configured to adjust the scissor height by sliding one of the fixed blade and the movable blade along the other blade.

For the former hair clippers, certain attachments are necessary to change the scissor height. In contrast, the latter clippers employ a mechanism for adjusting the scissor height by using a fixed blade formed in the form of a wedge. Therefore, the latter hair clipper can finely adjust the scissoring height only by the user changing the setting by his or her hand without using this specific attachment.

Japanese patent JP 3412834 B discloses a hair clipper comprising a handle ring attached to a main body incorporating a motor. In this clipper, the rotation of the handle causes forward / rear movement of the slider, thereby changing the position of the movable blade. As a result, the shearing height is changed. Further, according to the above Japanese patent, in order to move the slider forward / backward by the rotation of the handle ring, the handle ring is provided with an inclined cam groove on its inner surface, and the slider is fastened to be inserted into the cam groove. A linking pin is provided. In this clipper, the inclined cam groove has a first longitudinal side formed in a stepwise shape formed by alternating connection of a straight surface perpendicular to the forward / rear direction and an inclined surface inclined with respect to the front / rear direction. lengthwise side). With this hair clipper with the function of adjusting the height of the scissor, it is possible to stabilize the fastening pins.

However, the above-described Japanese patent discloses that only one of the longitudinal side surfaces opposite to the cam groove is formed in the stepped shape, and the other is formed in the inclined shape as a whole. In terms of the movable range of the fastening pins (sliders) in the forward / rear direction, only one longitudinal side comprises a straight surface perpendicular to the forward / rear direction. Therefore, in the position for keeping the adjusted scissoring height constant, the movable range of the fastening pin is relatively wide. Accordingly, vibrations generated by the rotation of the motor and the reciprocating motion of the movable blades are likely to cause forward / backward movement of the movable blades, thus causing slight fluctuations in the scissor height.

In view of the above disadvantages, the present invention aims to provide a hair clipper that facilitates adjusting the scissoring height to a desired height and which can maintain the adjusted scissoring height precisely in a constant state.

In this embodiment, the width Wb of the connecting groove 440 is equal to the dimension of the fastening pin 52 in the moving direction (diameter of the fastening pin 52).

For the cam groove 40, the width Wa of the holding groove 430 and the width Wb of the connecting groove 440 are the cam grooves 40 at the boundary between the holding grooves 430 and the connecting grooves 440. Is smaller than the width Wc. The width Wc of the cam groove 40 at the boundary between the holding groove 430 and the connecting groove 440 is the boundary between the stepped portion 43 and the inclined portion 44 and the inclined portion 43 and the inclined portion 44, respectively. It is defined as the distance between the boundary between the second stepped portion 43 and the second inclined portion 44 on the opposite side of the portion 44. That is, the second side surface 412 is formed such that the cam groove 40 has a smaller width at the stepped portion 43 than at the boundary between the stepped portion 43 and the inclined portion 44. That is, the second side surface 412 has a width Wa of the holding groove 430 (the width of the cam groove 40 in the step 43) at the boundary between the holding groove 430 and the connecting groove 440. Is designed to be smaller than the width Wc of the cam groove 40.

The cam groove 40 comprises paired longitudinal sides 41, 41 arranged in the axial direction of the handle ring 4. The longitudinal side surfaces 41 and 41 are formed in a stepped shape. Briefly described, as shown in FIGS. 1 and 8, each longitudinal side surface 41, 41 includes a plurality of stepped portions 43 and a plurality of inclined portions 44. The step portion 43 extends in a state substantially perpendicular to the axial direction (sliding direction of the slider 5).

While being positioned between the steps 43, the adjusted scissoring height " h " remains constant. Another opposing through the space between the inclined portions 44, 44 of each longitudinal side 41, 41 paired from the space between the step portions 43, 43 facing the fastening pins 52. Moving to the space between the steps 43 and 43, the scissor height " h " is changed to another height corresponding to the other opposing steps 43 and 43.

While the scissoring height "h" is selected, the fastening pins 52 are held between the stepped portions 43 and 43 facing in the axial direction. Therefore, unlike the prior art, one of the longitudinal side surfaces 41 and 41 is formed in a stepped shape, and the other is constituted only by the inclined portion 44 inclined with respect to the axial direction (sliding direction of the slider 5). It is possible, if necessary, to reduce the gap between the slider 5 in the sliding direction and the inner side of the cam groove 4. Thus, the adjusted scissoring height "h" can be successfully kept constant.

In addition, for the purpose of allowing the fastening pins 52 to move within the cam groove 40 and stabilizing the fastening pins 52 at a position associated with the required scissor height " h " if necessary, the spacing Wc is in the axial direction. It is selected to be larger than the distance Wa between the opposing step portions 43 and 43 at. The spacing Wc is the opposed longitudinal side face in the direction orthogonal to the normal of the fastening pin 52 at the outer corner between the stepped portion 43 of one longitudinal side 41 and the inclined portion 44 adjacent the stepped portion ( 41, 41). The opposing interval Wb between the opposing inclined portions 44 and 44 may be equal to the interval Wa. The spacing Wb is between the longitudinal side faces 41 and 41 opposite in the direction orthogonal to the normal of the fastening pin 52 at the point where the fastening pin 52 is in contact with the inclined portion 44 of one longitudinal side 41. It is set as interval. The interval Wb is preferably slightly larger than the interval Wa. With this configuration, it is possible to smoothly change the shearing height "h". That is, preferably, the gap between the fastening pin 52 and the inner surface (vertical side face 41) of the cam groove 40 determines the shear height "h" than at the position that changes the shear height "h". Becomes smaller.

In this embodiment, in order to successfully maintain the adjusted scissoring height "h", click producing means is provided. The click generating means is configured to generate a click feeling at the position that determines the scissor height "h". In brief, the click generating means is configured to generate a click feeling when the fastening pin 52 comes between the steps 43 and 43.

That is, the adjusting device comprises click generating means (click generating mechanism) configured to prevent relative movement of the fastening pin 52 with respect to the handle ring 4 when the handle ring 4 comes to a predetermined position. In this embodiment, the predetermined position includes a first position, a second position, a third position, a fourth position, and a fifth position. The first position is defined as the position where the fastening pin 52 is located at the step 431A (holding groove 430A) relative to the highest scissor height "h". The second position is defined as the position where the fastening pin 52 is located in the step 431E (holding groove 430E) relative to the lowest scissor height "h". The third position is defined as the position where the fastening pin 52 is located in the step 431B (holding groove 430B) relative to the second highest scissor height "h". The fourth position is defined as the position where the fastening pin 52 is located at the step 431C (holding groove 430C) relative to the third highest shear height "h". The fifth position is defined as the position where the fastening pin 52 is located at the step 431D (holding groove 430D) relative to the fourth highest scissor height "h".

This click generating means comprises a plurality of (five in the illustrated example) click recesses 45 (45A, 45B, 45C, 45D, 45E) and click protrusions (not shown) as shown in FIG. . The click projection is provided on the outer side of the main body 1, which is covered by the handle ring 4. The click projection is biased by a spring, thereby protruding from the outer side of the main body 1. The click recesses 45 are formed on the inner side of the handle ring 4 and are arranged at equal intervals in the circumferential direction thereof. When the handle ring 4 is positioned at a position that determines the scissor height "h", the click projection fits into the corresponding recess in the click recess 45 by spring force. Thereby, the movement of the handle ring 4 is prevented. In addition, the click protrusion is designed to be in contact with the inner surface of the click recess 45 when fitted to the click recess 45. In brief, when the click protrusion enters the click recess 45, a click feeling is generated. In this embodiment, the click recesses 45A, 45B, 45C, 45D, 45E correspond to the first position, the third position, the fourth position, the fifth position and the second position, respectively.

Further, for the purpose of clearly showing the adjustable range of the scissor height "h", the click generating means corresponds to the condition (first position) corresponding to the highest scissor height "h" and the lowest scissor height "h". It may be configured to generate a click feeling in response to only the condition (second position). While the fastening pin 52 is positioned between the opposing steps 42, 42 of the cam groove 40, the adjusted scissoring height “h” is successfully kept constant. As a result, even when the click generating means fails to prevent the movement of the handling ring 4 at a position other than the final position, an undesired change of the scissor height "h" is prevented.

The handling ring 4 is provided with a plurality of elongate protrusions 46 on the outer circumferential surface. The elongate protrusions 46 extend in the axial direction of the handle ring 4 and are spaced apart in the circumferential direction of the handle ring 4. Elongated protrusions 46 are provided to facilitate manual rotation of the handle ring 4. The elongated protrusions 46 are spaced at intervals corresponding to the positions that determine the scissor height " h ". Preferably, the elongate protrusion 46 is such that when the handle ring 4 is in a position to determine the scissor height "h", the elongate protrusion 46 and the display portion 30 provided on the head portion 3 are aligned. Is located.

10 illustrates an example corresponding to the above configuration. Specifically, in this example, the elongate protrusions 46 have dimensions in the axial direction corresponding to the associated shearing height " h ". In brief, when the lower scissor height "h" is selected, the indicator 30 is aligned with the shorter elongated protrusion 46. When a higher scissor height "h" is selected, the indicator 30 is aligned with the longer elongated protrusion 46. Thus, the user can know the current scissoring height " h " by checking the length of the elongated protrusion 46 provided as a finger stop.

In the example illustrated in FIG. 10, the handle ring 4 is provided with a plurality of finger stops (long protrusions) 46 on its outer side. The plurality of finger stops 46 includes finger stops 46 (46A-46E) each associated with a different scissor height "h". Finger stop "46A" is the first finger stop associated with the highest scissoring height "h". Finger stop "46E" is the second finger stop associated with the lowest scissor height "h".
