Description

  The present invention relates to a comb attachment attached to a clipper.

  Conventionally, a plurality of comb blades are converted into a reciprocating motion using a clipper blade portion formed by sliding a plurality of comb blades on each other, a driving force such as a motor, and a rotational force of the driving force. A comb having a comb tooth portion for introducing a part of hair into the clipper blade portion in a state of covering the clipper blade portion, in a clipper provided with a driving means for reciprocating at least one of the blades (movable blades) Attachments are known. As this type of comb attachment, there are known a round-cutting attachment that makes the cutting height constant, a taper attachment that cuts the sides around the left and right ears, and the like (for example, see Patent Document 1).

  By the way, the conventional comb attachment is provided with differently shaped comb teeth at both ends. For example, in the case of a round cut attachment, the height of the comb differs depending on the mounting direction, and it can be finished in two types of finished lengths. However, every time the cutting height is changed, it is necessary to remove the clipper from the main body once and change the mounting direction. Also, in the case of the taper attachment, there is a problem that there is a risk of failure unless the mounting direction is reversed when cutting the left and right sides. In addition, when the comb attachment was removed from the hair clipper body, visual confirmation was necessary to reattach it, which was very inconvenient.

Japanese Patent Laid-Open No. 9-84626

  The present invention has been invented in view of the above-mentioned conventional problems, and the object of the present invention is to remove the clipper body and change the mounting direction every time the cutting height, left and right side cuts, etc. are changed. In addition, an object of the present invention is to provide a clipper comb attachment that is capable of switching the function of the intended comb tooth portion without visual confirmation and is excellent in usability.

  In order to solve the above-mentioned problems, the present invention provides a comb member 8 by providing two or more types of comb teeth 8b at both ends in the length direction of the base portion 8a held by the clipper body 1, It is characterized in that any one type of comb tooth portion 8b can be appropriately selected and set at a position covering the clipper blade portion 3 without detaching the comb member 8 from the hair clipper main body 1.

  By adopting such a configuration, it becomes a non-detachable switching method that can be used by switching between the two types of comb tooth portions 8b without attaching and detaching the comb attachment from the clipper body 1, and cutting height and left and right side cuts as before. It is no longer necessary to remove the clipper body 1 and change the mounting direction each time it is changed. In addition, since only the rotation operation is required, the intended function of the comb tooth portion 8b can be switched without visual confirmation, and the usability is extremely improved.

  The central portion of the comb member 8 in the length direction of the base portion 8a is rotatably held on the clipper body 1 side, and the comb teeth 8b provided at both ends in the length direction of the base portion 8a are rotated. It is preferable that the clipper blade portion 3 is positioned on the locus. In this case, a non-detachable rotation method is adopted in which the function of each comb tooth portion 8b is switched by rotation without removing the comb member 8 from the clipper body 1. It becomes possible.

  Each of the comb teeth 8b provided at both ends of the comb member 8 is preferably formed in a tapered shape in which the protruding length d from the one side end toward the other end is gradually increased. In this case, for example, by rotating the comb member 8 when cutting both the left and right sides of the head, it is extremely easy to make the left and right finished angles θ1 and θ2 the same, and the difference in usability of the right and left hands can be eliminated. .

  Further, the comb member 8 is configured to be able to be pulled out in the direction away from the clipper blade part 3 from the initial position P1 covering the clipper blade part 3 while being held in the clipper body 1 and to be rotated at a predetermined pulling position P2. In this case, a series of operations for pulling and rotating the comb member 8 is facilitated, and the comb member 8 can be switched to a rotatable state only when the comb member 8 is intentionally pulled out. It becomes. Moreover, the pulling direction is opposite to the direction in which the load is applied to the comb member 8 when the clipper main body 1 is used, thereby preventing inadvertent rotation of the comb member 8 during use.

  The comb member 8 is preferably not rotatable at the initial position P1 other than the pull-out position P2, and in this case, the comb member 8 can be prevented from being inadvertently rotated at the initial position P1, thereby improving safety. Inadvertent contact of the comb member 8 with the clipper blade portion 3 during use can be prevented, and the blade portion 3 can be protected.

  The comb member 8 preferably includes a return spring 10 that applies a spring force from the pulling position P2 toward the initial position P1, and in this case, the pulling position P2 in the rotatable state is moved to the initial position P1. The return operation can be naturally performed using the return spring 10 without applying a load to the comb member 8, and the usability is further improved.

  Further, it is preferable to include a click rib 15 that gives a click feeling when the comb member 8 is pulled out from the initial position P1 to the pulling position P2 and returned from the pulling position P2 to the initial position P1. The comb member 8 can have a click feeling at the normal initial position P1 and the pull-out position P2, respectively, and can be easily recognized without visual confirmation.

  Further, the base portion 8 a of the comb member 8 is rotatably attached to the main body holding portion 9 held by the clipper main body 1, and the circular rotation larger than the rotation locus of the comb member 8 is attached to the main body holding portion 9. The groove 16 is preferably recessed. In this case, when the comb member 8 rotates, the main body holding portion 9 does not hinder the rotation due to the rotation groove 16, and the amount of pulling out the comb member 8 can be reduced, further rotating operation. Easy to do.

  Further, it is preferable to provide a fluff escape hole 17 for discharging the shavings in the base portion 8 a facing the main body holding portion 9, and in this case, hairs are formed in the gap between the base portion 8 a of the comb member 8 and the main body holding portion 9. Generation | occurrence | production of clogging of a waste can be prevented and the situation where the comb member 8 becomes difficult to return to the initial position P1 with a waste can be avoided.

  The present invention provides a clipper body every time the cutting height, left and right side cuts, etc. are changed by adopting a non-detachable switching system that can be used by switching between two types of comb teeth without detaching the comb attachment from the clipper body. Therefore, it is not necessary to change the mounting direction from the mounting position, and only the rotation operation is required. Therefore, the intended function of the comb tooth portion can be switched without visual confirmation, and the usability is improved.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in FIG. 1, the clipper of the present embodiment transmits a driving force of a clipper body 1 incorporating a drive source such as a motor, a switch handle 2 for turning on and off the clipper body 1, and a motor and the like to reciprocate. It is comprised by the clipper blade part 3 which moves. The clipper blade portion 3 is composed of a movable blade 4 and a fixed blade 5, and the movable blade 4 reciprocates and cuts hair and body hair by being sandwiched with the fixed blade 5.

  As the comb attachment 7 attached to the clipper main body 1, in this embodiment, as shown in FIG. 2, a taper attachment (hereinafter referred to as a taper attachment 7) capable of making the left and right finishing angles the same is exemplified.

  As shown in FIG. 3, the taper attachment 7 includes a main body holding portion 9 that is held by the clipper main body 1 and a comb member 8 that is rotatably attached to the main body holding portion 9. .

  The main body holding portion 9 is formed in a substantially U-shape in which a pair of locking portions 9b are raised from both ends of the bottom plate portion 9a so as to face each other, and a pair of main body mounting bosses 13 and 13 are formed from the inner surface of each locking portion 9b. (FIG. 2 (c)) is projected.

  From the upper surface portion of the comb member 8, the pair of main body mounting bosses 13 are fitted to the pair of left and right main body hole portions 6 (FIG. 1A) recessed in the left and right end surfaces of the clipper main body 1. The plurality of protruding portions 18 (FIG. 3) projectingly come into contact with a plurality of locations on the back surface of the clipper main body 1, so that the positional relationship of the main body holding portion 9 with respect to the clipper main body 1 remains unchanged. That is, the main body holding portion 9 can be held with respect to the hair clipper main body 1 by the concave-convex fitting between the main body mounting boss 13 and the main body hole 6 and the contact between the protrusion 18 and the back of the hair clipper main body 1. At the same time, the main body holding portion 9 can be removed by removing the concave-convex fitting between the main body mounting boss 13 and the main body hole 6.

  As shown in FIG. 2, the comb member 8 includes a base portion 8a that is rotatably attached to the main body holding portion 9, and two types of comb teeth portions 8b provided at both ends of the base portion 8a in the length direction. , 8b are integrally formed. As shown in FIG. 2A, the comb teeth 8b and 8b are projected lengths d → d1 from the one side end 8b1 toward the other side end 8b2 in the cutting edge direction (left and right direction in FIG. 2A). Is formed in a tapered shape that gradually increases. Here, the taper angle θ is set to the same angle (for example, 10 degrees). Of course, the present invention is not limited to this, and the taper angle θ may be changed to, for example, 5 degrees and 10 degrees. Further, as shown in FIG. 2B, the lower surfaces 8b3 of the respective 8b and 8b are respectively lowered so that the heights h of the comb teeth portions 8b and 8b gradually decrease from the proximal end side toward the distal end side. It is formed in a taper shape.

  Next, the pull-out mechanism and the rotation mechanism of the comb member 8 will be sequentially described.

  The drawer mechanism is shown in FIGS. A distal end portion of the spring holding member 11 is slidably penetrated from below through a through hole 19 provided at the center of the base portion 8a of the comb member 8, and a screw is provided at the center of the main body holding portion 9 of the comb member 8. A screw 12 that is provided with a hole 9 c and is inserted and locked into the screw hole 9 c from above the main body holding portion 9 is screwed into an inner screw at the tip of the spring holding member 11. The holding member 11 is fixed. Further, the upper end of the return spring 10 provided on the outer periphery of the spring holding member 11 is in elastic contact with the lower surface of the base portion 8 a, and the lower end of the return spring 10 is supported by the spring receiving portion 20 provided at the lower end of the spring holding member 11. Thus, the base portion 8a of the comb member 8 is always in close contact with the main body holding portion 9 by the spring force of the return spring 10, and the comb member 8 is moved away from the clipper main body 1 (downward in FIG. 5). By pulling by hand, the return spring 10 contracts, and the comb member 8 can be pulled out from the initial position P1 (FIG. 4) to the pulling position P2 (FIG. 5) in the unlocked state.

  Next, the rotation mechanism will be described.

  As shown in FIG. 4, a pair of left and right boss holes 9 d are opened on both sides of the screw hole 9 c of the main body holding portion 9, and from a portion facing the boss hole 9 d of the base portion 8 a of the comb member 8. When the comb holding bosses 14 are provided so that the comb member 8 is in the initial position P1, the comb holding boss 14 is fitted into the boss hole 9d so that the comb member 8 cannot be rotated. 5, when the comb holding boss 14 and the boss hole 9d are disengaged from each other, the fixed state is released, and the comb member 8 is rotated 360 degrees around the screw 12.

  Further, a rotation groove 16 for avoiding contact with the main body holding portion 9 is provided on the upper surface of the base portion 8a of the comb member 8. In this example, the radius B of the rotation groove 16 is set to be larger than the maximum radius A of the main body holding portion 9 as shown in FIG. 2C so that interference with the main body holding portion 9 can be prevented when the comb member 8 rotates. Set slightly larger. The rotation groove 16 has a structure in which the pull-out dimension of the comb member 8 is suppressed to a small size, and the protrusion height above the comb tooth portion 8b around the rotation groove 16 is increased to increase the strength.

  Further, a concave portion 30 into which the bottom plate portion 9a of the main body holding portion 9 is inserted in and out is formed on the bottom surface on the center side of the rotating groove 16. Here, as shown in FIG. 6, when the bottom plate portion 9a is inserted into the recess 30, the depth of the recess 30 is determined so that the upper surface of the bottom plate portion 9a and the upper surface of the base portion 8a are flush with each other. . Further, as shown in FIG. 7, both side surfaces of the concave portion 30 are inclined surfaces 30 a that are inclined in a reverse H-shaped cross section, while the lower side surfaces of the bottom plate portion 9 a are the same as the inclined surfaces 30 a of the concave portion 30. The inclined surface 9f is inclined at an angle, and when the comb member 8 is pulled out and rotated, the comb member 8 is lifted by the inclined surfaces 30a and 9f, so that the transition from the drawer to the rotation operation can be smoothly performed, and further the rotation. When the subsequent comb member 8 is returned to the initial position P1, the comb member 8 can be smoothly positioned with respect to the main body holding portion 9 by using the inclined surfaces 30a and 9f.

  Here, in order to switch from the use state of one comb tooth portion 8b of the comb member 8 having the above configuration to the use state of the other comb tooth portion 8b, first, the comb member 8 at the initial position P1 in FIG. Pulling downward, pulls out to the pulling position P2 where the fixation in FIG. 5 is released (FIG. 8 (a) → (b)). When the comb member 8 is rotated 180 degrees around the screw 12 in this state, the other comb tooth portion 8b is moved to a position covering the blade portion 3 as shown in FIG. 8 (c) → (d) → (e). At this stage, the comb member 8 naturally returns to the initial position P1 by the spring force of the return spring 10, and the switching is completed. Thus, for example, when cutting both the left and right sides shown in FIG. 9, the left and right finished angles θ1 and θ2 can be made the same by rotating the comb member 8 and using the comb teeth 8b at both ends separately. The difference in usability of the left hand can be resolved.

  Thus, the central portion of the comb member 8 in the length direction of the base portion 8a is rotatably held on the hair clipper main body 1 side, and the comb teeth portions 8b provided at both ends of the base portion 8a in the length direction are rotated. Since the clipper blade portion 3 is positioned on the locus, the non-detachable rotation switching method can be used by switching between the two types of comb tooth portions 8b without attaching or detaching the taper attachment 7 from the clipper main body 1. Therefore, it is not necessary to remove the attachment from the clipper main body 1 and change the mounting direction as in the conventional case. That is, it is only necessary to rotate the taper attachment 7, and the intended comb tooth portion 8b can be switched without visual confirmation.

  Further, the comb member 8 is configured to be able to be pulled out in the direction away from the clipper blade part 3 from the initial position P1 covering the clipper blade part 3 while being held in the clipper body 1 and to be rotated at a predetermined pulling position P2. Therefore, a series of operations for pulling out and rotating the comb member 8 is facilitated, and the comb member 8 can be switched to a rotatable state only when the comb member 8 is intentionally pulled out. Moreover, the pulling direction is opposite to the direction in which the load is applied to the comb member 8 when the clipper main body 1 is used, thereby preventing inadvertent rotation of the comb member 8 during use. That is, unless the comb member 8 is intentionally pulled out from the initial position P1 to the pull-out position P2, the comb member 8 cannot be switched to a rotatable state, and the safety of use can be ensured, and the clipper blade portion 3 can be used at the time of use. Inadvertent contact of the comb member 8 can be prevented, and the blade 3 can be protected.

  Further, as shown in FIGS. 6B and 7B, the comb member 8 is provided with a storage portion 33 for storing the spring holding member 11, and a pair of clicks are provided on both inner wall surfaces of the storage portion 33. Ribs 15 are projected. When the comb member 8 is pulled out from the initial position P1 to the pull-out position P2, the operation feel changes when the outer peripheral end 21 of the spring holding member 11 gets over the click rib 15, and the pull-out position P2 can be easily set regardless of visual recognition. Can be recognized. After that, when the comb member 8 returns, the operation feeling similarly changes, so that it can be easily recognized without visual confirmation.

  Further, a fluff escape hole 17 shown in FIG. 7 is provided in the base portion 8a of the comb member 8. As a result, it is possible to prevent clogging in the gap between the base portion 8a of the comb member 8 and the main body holding portion 9, and there is an advantage that it is possible to avoid a situation in which the comb member 8 is unlikely to return to the initial position P1 due to fuzz.

  Although the taper attachment 7 has been exemplified in the above-described embodiment, the present invention can be similarly applied to a round cutting attachment that finishes at a fixed cutting height. As an example of the round cutting attachment, a cutting height of one comb tooth portion 8b is 3 mm, for example, and a cutting height of the other comb tooth portion 8b is 6 mm, for example.

  In addition to the cutting height function and the right and left side and neckline trimming functions, the comb tooth portion 8b functions as a ski trimming function, a volume drop function, or a line alignment that cuts along the line you want to align with the hair. It can be widely applied to comb attachments having various functions.

  In addition, a non-detachable method for switching without attaching and detaching includes a method for changing the height of the comb itself in addition to the rotating method.
