Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a split end trimmer.

[Prior Art] Conventionally, in this type of split hair trimmer, the blade of the blade attachment part, which is movable within the case, is inserted into the notch for hair insertion through the through hole, and then the blade body contacts the abutting surface of the notch through the through hole. There are some that are configured to be pressed against the

Then, when you put the split ends to be cut into the hair insertion notch of the split end cutter and press the operation part of the blade attachment part, the blade moves to the contact surface in the hair insertion notch and cuts the hair. The blade contacts the hair and moves the split ends toward the contact surface, so that the split ends are sandwiched between the blade and the contact surface and cut.

[Problems to be Solved by the Invention] However, before cutting the split ends, the above-mentioned split ends trimmer brings the blade into contact with the split ends to move the split ends to the contact surface. Therefore, for example, if a user starts pressing the operation part of the blade attachment part in an attempt to cut split ends, but halfway through the operation, he or she realizes that the hair is normal and is dissuaded and stops this operation. The blade is in contact with the hair, and thin, weak hair may be cut by just this contact. Furthermore, even if the hair is not cut, it is easy to imagine that it will damage delicate hair.

The above happens not only when the pressing operation of the operation part is stopped midway, but also when the user unconsciously presses the operation part halfway, the blade inside the case passes through the hole and cuts into the hair insertion notch. This will cause it to stick out in some areas. For this reason, if you insert hair into the hair insertion notch and slide it down to the split end,
Similar to the case described above, there is also the problem that the blade cuts or damages normal hair.

The purpose of the present invention is to provide a split end trimmer that can prevent the user from cutting off normal hair or damaging the hair against the user's will. It is in.

[Means for solving the problem] The first idea is to form a notch for inserting bristles on one side of the blade case, and insert the cutting edge into the notch for inserting bristles through a through hole formed in the notch. The blade body is fixed in the blade case so as to face each other, and a movable member is provided in the case so as to move in and out of the hair insertion notch through the through hole. The gist of this is a split hair trimmer in which a movable member has a contact surface that can contact the cutting edge of a blade.

The second idea is to form a notch for inserting bristles on one side of the blade case, and insert the cutting edge into the case through a hole formed in the notch so that the cutting edge faces the notch for inserting bristles. In addition to fixing the blade body, a movable member is provided in the case so as to move in and out of the hair insertion notch through the through hole, and an abutment that can come into contact with the cutting edge of the blade body as the movable member moves in and out. The contact surface is formed on a movable member, and the case is provided with a leaf spring that can be elastically deformed along the side surface of the blade body so as to contact the contact surface of the movable member before the cutting edge of the blade body. Its gist is a hair clipper.

The third idea is to fix the blade in a blade case, and also support a movable member in the case so as to be movable with respect to the case, and the movable member has the cutting edge of the blade as it moves. A stopper means is provided between the movable member and the case to restrict movement of the movable member so as to bring the contact surface of the movable member into pressure contact with the cutting edge of the blade. The gist is a split end trimmer equipped with a.

[Function] As the movable member moves, its abutting surface protrudes into the hair insertion notch and moves the split hairs in the notch toward the blade body, and the movable member moves the split hairs between the abutting surface and the cutting edge of the blade body. Pinch and cut. The contact surface of the movable member, which does not perform the cutting action, moves the split ends to the cutting edge of the blade, so even if the movable member stops moving midway, the split ends will not be in contact with the contact surface at that point. Since the split ends are only left in place, the split ends are not cut or damaged.

When cutting the split ends, the leaf spring is pushed by the contact surface and elastically deforms along the side of the blade. When the contact surface of the movable member separates from the cutting edge of the blade, the leaf spring uses its elasticity to separate the cut split ends from the cutting edge of the blade.

Even if the movable parts are operated with more force than necessary,
Since the stopper means prevents the cutting edge of the blade body from being pressed against the contact surface, the cutting edge will not be damaged.

[Example] An example embodying this invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3, a movable member 2 is rotatably attached to a shaft 3 in a blade case 1 serving as a handle, and one side of the movable member 2 is transparently attached to the blade case 1. The movable member 2 is exposed to the outside of the case 1 through the notch 1a, and this portion of the movable member 2 serves as an operating portion 2a. The movable member 2 is biased by a screw coil 4 in a direction to cause the operating portion 2a to protrude outward from the blade case 1, and the base of the operating portion 2a is in contact with the inner surface of the blade case 1 under normal conditions.

An elongated hair insertion notch 5 is formed on the tip side of the blade case 1, and an elongated through hole 6 that communicates between the inside and outside of the main body case 1 is formed around the entire periphery of the hair insertion notch 5.
is formed. The contact surface 2b formed on one side of the movable member 2 is normally recessed into the blade case 1 through the through hole 6 due to the urging force of the screw coil 4.

The blade body 7 is located in the case 1 on the side facing the movable member 2 across the hair insertion notch 5 in the blade case 1.
The cutting edge 7a of the blade body 7 is fixed by caulking to the
is slightly recessed from the through hole 6 of the hair insertion notch 5. The blade body 7 is sandwiched between a U-shaped groove 8a formed on the distal end side of a leaf spring 8, and the base end of the leaf spring 8 is held by a supporting protrusion 1b of the blade case 1. Fixed inside. The leaf spring 8 faces the hair insertion notch 5 within the through hole 6, and can be bent downward along the side surface of the blade body 7 around its base end.

A pair of stopper surfaces 9 are formed on both sides of the operating portion 2a of the movable member 2, and stopper surfaces 10 are formed on both sides of the notch 1a on the blade case 1 side so as to correspond to both stopper surfaces 9. There is.

Next, a case will be described in which split ends are cut using the split end cutter configured as described above.

As shown in FIGS. 4 and 5, when the user grasps the blade case 1, inserts the split ends to be cut into the hair insertion notch 5, and presses the operating section 2a of the movable member 2, The movable member 2 rotates around a shaft 3, and its contact surface 2b protrudes into the hair insertion notch 5 through the through hole 6b, and moves the split hairs in the notch 5 toward the blade body 7. It is moved to come into contact with the plate spring 8. When the user further presses the operation part 2a,
The contact surface 2b of the movable member 2 bends the leaf spring 8 downward with the split ends sandwiched between it and the leaf spring 8,
The cutting edge 7a of the blade body 7 contacts, and the split ends contact 2b.
and the cutting edge 7a and are cut. Also,
At the same time, both stopper surfaces 9 of the movable member 2 come into contact with the stopper surfaces 10 of the blade case 1, respectively, and prevent the movable member 2 from rotating any further.

Furthermore, when the user stops pressing the operating part 2a and releases his/her finger from the operating part 2a, the movable member 2 rotates due to the biasing force of the screw coil 4, and the contact surface 2b
is separated upward from the cutting edge 7a of the blade body 7, and the split end trimmer returns to its original state as shown in FIGS. 1 and 2. In addition, since the leaf spring 8 is released from the pressure of the contact surface 2b and springs upward due to its elasticity, the cut split ends are transferred to the blade body 7 within the hair insertion notch 5.
It is separated from the cutting edge 7a.

In this way, in the split hair trimmer of this embodiment, the contact surface 2b of the movable member 2, which does not perform a cutting action, comes into contact with the split ends, and this contact surface 2b removes the split ends from the blade body 7. In order to move the hair to the cutting edge 7a and cut it, for example, the user starts pressing the operating part 2a in an attempt to cut split ends, but halfway through the operation, he realizes that the hair is normal and is dissuaded and stops the pressing operation. Even in this case, since the contact surface 2b is only in contact with the hair at that point, there is no risk of cutting normal hair or damaging the hair.

Further, even if the user unconsciously presses the operating part 2a halfway, only the contact surface 2b of the movable member 2 protrudes from the hair insertion notch 5, so that the hair insertion Even if the hair is inserted into the insertion notch 5 and the hair is slid to a split end, there is no risk of cutting normal hair or damaging the hair.

Furthermore, in the split hair trimmer of this embodiment, when the blade 7 cuts the split ends between the contact surface 2b and the movable member 2 and the blade case 1, the stop surfaces 9 and 10 of the movable member 2 and the blade case 1 are connected to each other. The movable member 2 that comes into contact with
In order to prevent the rotation of the operating part 2a, even if the user presses the operating part 2a with more force than necessary,
The abutting surface 2b is not pressed against the cutting edge 7a of the blade body 7 and will not damage the cutting edge 7a.

On the other hand, in the split end trimmer of this embodiment, the leaf spring 8 separates the cut split ends from the cutting edge 7a of the blade body 7, so the cut split ends do not remain attached to the cutting edge 7a. .

The split hair trimmer of this embodiment includes stopper surfaces 9 and 10 to prevent damage to the cutting edge 7a of the blade body 7, and a leaf spring 8 to remove cut split ends. However, it is not necessary to provide the stopper surfaces 9, 10 and the leaf spring 8.

Further, in the split end trimmer of this embodiment, the movable member 2 and the blade body 7 are housed in the blade case 1, but it is not necessary to configure them in this way, and these members may be exposed to the outside. .

[Effects of the invention] As detailed above, the split end trimmer of the present invention does not cut normal hair against the user's will or damage the hair. This has the excellent effect of being able to prevent this from happening.

Furthermore, the split ends trimmer of the present invention has the excellent effect of separating the cut split ends from the cutting edge of the blade body and preventing the split ends from adhering to the cutting edge.

Furthermore, the split end trimmer of the present invention provides an excellent effect in that even if the movable member is operated with an unnecessarily strong force, the cutting edge will not be damaged.
