Description

  The present invention relates to scissors.

  As the scissors, one using a middle finger and an index finger is known (see Patent Document 1). As shown in FIG. 10, the scissors 50 are provided with combs 53 when used with the middle finger and index finger inserted in the bands 51 and 52. The scissors 50 move the two blades 54 and 54 around the fulcrum 55 by moving the middle finger and the index finger horizontally to cut the hair, and comb the hair with the comb 53.

JP 2006-297000 A

  However, in the scissors described in Patent Document 1, the fulcrum 55 of the scissors 50 is located between the middle finger and the base of the index finger as shown in FIG. Therefore, when the hair is cut with the scissors 50, the portion of the fulcrum 55 and the vicinity thereof cannot be used as the hair cutting region, which is inefficient. In addition, the open state of both fingers and the open state of the blades 54, 54 of the scissors 50 do not match, and a sense of cutting hair with fingers is not obtained, and it is convenient for the user of the scissors 50 to cut their hair. It is bad.

  Accordingly, an object of the present invention is to provide a scissor that is easy to use when a scissor user cuts his / her hair and that can efficiently cut the hair.

In order to achieve the above object, the scissors of the present invention include a pair of blades that are rotatable around a fulcrum, a holder that is attached to a region where the blades of each blade do not overlap, and each holder. A pair of blades that cut the user's own hair in a pair of scissors provided with a hole penetrating in a direction from the fulcrum portion toward the blade edge and into which a finger of a human hand can be inserted. The center of the fulcrum part in the direction orthogonal to the direction of the opening / closing operation of the pair and the center of the hole in the direction orthogonal to the direction of the opening / closing operation of the pair of blades are shifted in the direction orthogonal to the direction of the opening / closing operation of the pair of blades When the hair is placed so that the head comes to one of the two end faces in the orthogonal direction of the holder attached to each of the pair of blades, and the head is placed so that the head comes to the other of the both end faces When cutting hair Also it is possible, by selecting the one, in which are configured to be able to vary the length to cut hair.

  Here, the deviation is preferably 7 to 12 mm, and the distance between the center of the hole of the holder and the end surface of the fulcrum portion closer to the center is preferably 5 to 10 mm.

  Further, it is preferable that only one holder is attached to each blade at a position that is 1/5 or more of the distance from the fulcrum portion to the blade edge of the blade and away from the position of the fulcrum portion in the blade edge direction.

  Also, on the side between the fulcrum part and the blade edge and close to the fulcrum part, a step part in which the blade is bent in a direction orthogonal to the opening / closing operation direction of the blade is formed, and the blade edge side from the step part Further, it is preferable that a holder is attached.

  In addition, the holders are respectively attached at positions facing each other when the pair of blades are closed, and projecting stoppers that prevent the facing surfaces from approaching each other by a predetermined distance or more are provided on the facing surfaces of the holder. Preferably it is formed.

  In addition, when the direction perpendicular to the operation direction of the holder accompanying the blade opening / closing operation is the thickness direction of the holder, the upper end surfaces in the thickness direction of all the holders are on the same plane, and the lower end surfaces are also the same plane. It is preferable that the center in the thickness direction of the blade is attached at a position 1/10 to 1/2 of the thickness of the holder from the lower end surface or the upper end surface.

  According to the present invention, it is possible to provide scissors that are easy to use when the user of scissors cuts their hair and that can cut hair efficiently.

It is a figure which shows the state which opened the index finger and the middle finger from the state shown in FIG. 8, and opened the scissors. It is a figure which shows the conventional scissors.

  Hereinafter, the structure of the scissors according to the embodiment of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a plan view showing a state in which the scissors 1 according to the first embodiment of the present invention are closed. FIG. 2 is a front view of the scissors shown in FIG. FIG. 3 is a right side view of the scissors shown in FIG.

  The scissors 1 have a pair of blades 2 and 3 of a metal flat blade 2 and a blade 3. The blades 2 and 3 are formed with circular holes on the fulcrum side when opening and closing (not shown). And it can be rotated centering on a fulcrum part K (shown by a black circle in FIG. 1 for convenience) which is a central axis of the pin 4. The two pressing plates 5 in which a circular hole (not shown) is formed at the position of the fulcrum portion K is a portion where the blades 2 and 3 overlap each other, and the portion where the circular hole is formed from the outside. It arrange | positions so that it may overlap on each surface of the blades 2 and 3 further. The pin 4 passes through the circular holes of the blades 2 and 3 and the circular holes of the two pressing plates 5. In addition, the pin 4 has a cylindrical portion that passes through each circular hole serving as a central portion, and both ends thereof are circular holes of the blades 2 and 3 and circular holes of the two pressing plates 5. It has a disk-like shape with a diameter larger than each diameter. The blades 2 and 3 partially overlap when viewed from the central axis direction. In a state where the scissors 1 are closed, the overlapping range of the blades 2 and 3 is gradually narrowed from the fulcrum K toward the blade tip T. The fulcrum constituent part including the fulcrum part K is formed from the rear end parts of the blades 2 and 3, the pin 4 and the pressing plate 5.

   Further, the blades 2 and 2 have a step in the direction perpendicular to the direction of the opening / closing operation of the blades 2 and 3 between the fulcrum portion K and the blade tips T of the blades 2 and 3 and close to the fulcrum portion K. Step portions 6 and 7 are formed by bending 3. In the stepped portion 6, the blade 2 and the blade 3 are bent about 45 degrees from the flat plate portion on the tip side of the blade 2 and the blade 3. The step portion 7 is bent about 45 degrees in the opposite direction to the step portion 6. As a result, the blades 2 and 3 in the range from the step portion 7 to the fulcrum portion K and the blades 2 and 3 in the range from the cutting edge T of the blade 2 and the blade 3 to the step portion 6 are formed in parallel. ing.

  In addition, two circular holes 8 are formed between the stepped portions 6 of the blades 2 and 3 and the cutting edge T and on the stepped portion 6 side (the cutting edge T side with respect to the stepped portion 6). Two holes 8 are formed side by side from the fulcrum part K toward the cutting edge T in the region of the blades 2 and 3 where the blades 2 and 3 do not overlap each other. When the scissors 1 according to this embodiment are closed, the width W1 is 10 mm, the total length L1 is 65 mm, the blade length L2 of the tip side flat portion which is a so-called blade portion is 40 mm, and the plane portion on the fulcrum K side The fulcrum side length L3 is 15 mm, and the length L4 seen in the plan view of the stepped portions 6 and 7 is 10 mm.

  A holder 11, which is a polyethylene resin molded body, is attached to the hole 8. The holder 11 is provided with a finger insertion hole 12 into which a finger of a human hand can be inserted. The holder 11 is outsert molded so that the hole 8 is filled with resin. The center in the height direction of the blade portions of the blades 2 and 3 is located at the height position of the center C of the finger insertion hole 12 of the holder 11 (shown as the center line in the height direction in FIG. 3). The finger insertion hole 12 penetrates in a direction from the fulcrum portion K of the blades 2 and 3 toward the cutting edge T. The cross section of the finger insertion hole 12 is a square shape with four corners being curved, and as described above, a finger of a human hand, for example, an index finger and a middle finger can be inserted.

  Note that the center M in the height direction of the fulcrum portion K, that is, the fulcrum portion K, is arranged so as to be shifted in the height direction with respect to the center of the finger insertion hole 12 of the holder 11 due to the presence of the step portions 6 and 7 described above. ing. The deviation G1 is 10 mm when the center of the central axis of the pin 4, which corresponds to the center M, is the position of the fulcrum K. The thickness W2 in the height direction of the holder 11 is 28 mm, and the width W3 in the height direction of the finger insertion hole 12 is 20 mm. The upper end surfaces 14 and 14 in the height direction of the two holders 11 are configured to be in the same plane, and the lower end surfaces 15 and 15 are also configured to form the same plane. Further, the lateral widths W4 and W5 of the finger insertion holes 12 have different lengths. That is, the finger insertion hole 12 on the right side of FIG. 3 into which the thick middle finger enters is made longer. In this embodiment, the width W4 of the finger insertion hole 12 for the middle finger is 25 mm, and the width W5 of the finger insertion hole 12 for the index finger is 20 mm. However, the widths W4 and W5 may be the same. As for the width W3, the finger insertion hole 12 for the middle finger (right side in FIG. 3) may be larger than the finger insertion hole 12 for the index finger (left side in FIG. 3). Here, the insertion of the thumb is enabled by increasing the width W4 of the finger insertion hole 12 to 25 mm. That is, the scissors 1 can be opened / closed with the index finger and the middle finger, or can be opened / closed with the thumb and the index finger.

  Further, only one holder 11 is attached to each of the blades 2 and 3 at a position about 3/5 of the distance from the fulcrum K to the blade tips T of the blades 2 and 3. To describe this state in detail, the distance L5 from the center in the length direction of the holder 11 to the cutting edge T is 25 mm, and the distance from the end portion on the fulcrum K side of the scissors 1 to the center in the length direction of the holder 11 L6 is 40 mm, and the distance L7 from the fulcrum K to the center in the length direction of the holder 11 is 32.5 mm. The length L8 of the holder 11 is 15 mm, and the distance between the centers of the holes 8 and 8 is 8 mm. As a result, the center in the length direction of the holder 11 is a position of 32.5 mm which is about 3/5 with respect to the distance of 57.5 mm from the fulcrum part K to the cutting edge T. The distance L7 between the center in the length direction of the holder 11 and the fulcrum part K is preferably 40 to 70% of the distance between the fulcrum part K and the cutting edge T in terms of operation, and is preferably 50 to 60%. Further preferred.

  The two holders 11 are formed with protruding stoppers 13 having the same shape at positions facing each other when the blades 2 and 3 are closed. The stopper 13 serves to prevent the blades 2 and 3 from rotating excessively. Each stopper 13 has a rectangular parallelepiped shape, but may have a cylindrical shape. The stopper 13 may have a shape in which one side is long and the other is short. Moreover, although the upper end of the pin 4 is arrange | positioned so that it may become the same height as the upper end surfaces 14 and 14, it may jump out of the upper end surfaces 14 and 14 and may enter into the center C side.

  FIG. 4 is a plan view showing a state in which the scissors 1 are opened. The blades 2 and 3 rotate around the fulcrum portion K from the state shown in FIG. In FIG. 2, the blades 2 and 3 of the stepped portions 6 and 7 are drawn so as to be in close contact with each other, but actually there is a slight gap between the blades 2 and 3. Therefore, when the scissors 1 are opened and closed, the blades 2 and 3 of the steps 6 and 7 do not collide with each other, and the opening and closing operations are smooth. In addition, you may make it not produce a clearance gap in the part with which the blades 2 and 3 overlap.

  The scissors 1 are usually arranged with their heads in the state shown in FIG. However, you may make it cut the hair of the head which comes below in the state turned upside down from the state shown in FIG.

(Second Embodiment)
FIG. 5 is a plan view showing a state in which the scissors 21 according to the second embodiment of the present invention are closed. FIG. 6 is a front view of the scissors 21 shown in FIG. FIG. 7 is a right side view of the scissors 21 shown in FIG. The scissors 21 do not have the step portions 6 and 7 that the scissors 1 have, and the blades 2 and 3 are substantially complete flat plates. Further, the blades 2 and 3 of the scissors 21 are arranged so as to be shifted in the height direction of the center C of the finger insertion hole 12 of the holder 11. Otherwise, the scissors 21 are structurally the same as the scissors 1. Therefore, in FIGS. 5-7, the same code | symbol is attached | subjected to the element or member equivalent to each element or member of the scissors 1, and those description is abbreviate | omitted. Further, the opened state of the scissors 21 is the same as the opened state of the scissors 1 shown in FIG.

  As shown in FIG. 7, the direction orthogonal to the operation direction of the holder 11 accompanying the opening and closing operation of the blades 2 and 3 is defined as the thickness W2 direction of the holder. In that case, the upper end surface 22 in the thickness W2 direction of the holder 11 is on the same plane, and the lower end surface 23 is also on the same plane. The center P of the blades 2 and 3 in the direction of the thickness W6 is attached to the position of ¼ of the thickness W2 of the holder 11 from the lower end surface 23. Specifically, the distance between the center P and the lower end surface 23 is 3 to 5 mm. Therefore, the center P of the fulcrum portion K of the scissors 21 is arranged 9 to 11 mm away from the center C of the finger insertion hole 12 of the holder 11 in the height direction.

  When the scissors 21 are arranged so that the person's head comes under the scissors 21 in the state of FIG. 6, the hair is cut to a length of about 3 to 5 mm, and the scissors 21 are turned upside down in FIG. When placed so as to be under the scissors 21, the hair is cut to the thickness of fingers, that is, about 23 to 25 mm. As described above, the scissors 21 are standard in two ways upside down, so the width W4 of the two finger insertion holes 12 is set to 25 mm, which is the same as W5. Therefore, when the scissors 21 are used in two ways upside down, the thumb can be used in both ways.

(Main effects obtained by the embodiment of the present invention)
FIG. 8 is a view showing a state in which the index finger and the middle finger are inserted into the finger insertion hole 12 of the scissors 1 in the closed state, and FIG. 9 is a view in which the index finger and the middle finger are opened from the state shown in FIG. FIG. The scissors 1 and 21 according to the embodiment of the present invention are arranged such that the centers M and P in the height direction of the fulcrum part K are shifted in the height direction with respect to the center C of the finger insertion hole 12 of the holder 11. ing. Therefore, when the finger is inserted into the finger insertion hole 12 and the blades 2 and 3 from the cutting edge T to the step 6 or the entire blades 2 and 3 are parallel to the fingers, It becomes easy to position the presser plate 5 on the back of the hand or the palm. Then, the scissors 1 and 21 can easily use the fulcrum part K of the scissors 1 and 21 and the vicinity thereof as a region for cutting hair. Moreover, the open state of both fingers and the open state of the blades 2 and 3 of the scissors 1 and 21 are the same. Therefore, the scissors 1 and 21 are easy to use in the sense of a fingertip when the user of the scissors 1 and 21 cuts their hair, and can efficiently cut the hair. The blades 2 and 3 at the fulcrum portion K can support the scissors 1 and 21 by positioning the pressing plate 5 on the back of the hand or the palm, and can stabilize the operation of the scissors 1 and 21. .

  Moreover, since the conventional scissors 50 place a fulcrum at the base between the index finger and the middle finger, the movable range of the blades 54 and 54 is restricted to be small, and the pressing force (spring back) of the blades 54 and 54 is lacking. Therefore, the scissors 50 have a problem in that it is difficult to obtain an important blade as a scissor and a pressing function of the blade, and if the size is increased, the finger is fully opened and the practicality is poor. However, since the scissors 1 and 21 do not restrict the movable range of the blades 2 and 3 to be small, this problem is solved.

  The scissors 1 and 21 are particularly effective for trimming the hem of the back of the head, and can be used with a normal sharpness with a sense of picking the hair with the fingertip while confirming the presence of the hair with the belly of the finger. I can do it. The scissors 1 and 21 can be used with the thumb and index finger. In that case, the operation stroke of the blades 2 and 3 can be overwhelmingly large compared to the use with the index finger and the middle finger, and the usability is extremely improved. In addition, the scissors 1 and 21 can be used with peace of mind by those who are blind, and are also convenient for those who cannot go to the barber for a long time.

  The scissors 1 are arranged such that the center M of the fulcrum part K is 10 mm in the height direction with respect to the center C of the finger insertion hole 12 of the holder 11, and the center P of the fulcrum part K of the scissors 21 is shifted by 9 to 11 mm. The range of this deviation is a range suitable for making the blade tips T of the blades 2 and 3 parallel to the fingers while the pressing plate 5 of the fulcrum K is positioned on the back or palm of the hand as described above. From such a viewpoint, it is preferable that the deviation is 7 to 12 mm.

  Further, the holder 11 of the scissors 1 and 21 is about 3/5 of the distance from the fulcrum part K to the cutting edge T of the blades 2 and 3 and is placed on the blades 2 and 3 at positions away from the fulcrum part K in the cutting edge T direction. Only one is attached. Therefore, as described above, the holder 11 is disposed only in the central portion in the length direction of the blades 2 and 3, and the fulcrum portion K of the scissors 1 and 21 and the vicinity thereof can be used as a hair cutting region. From such a viewpoint, it is preferable that the holder 11 is disposed at a position that is 1/5 or more of the distance from the fulcrum part K to the cutting edge T of the blades 2 and 3 and away from the position of the fulcrum part K in the cutting edge T direction. 45% or more is more preferable. Further, since it is difficult to use if it is too far away, the distance from the position of the fulcrum K to the cutting edge T is 80% or less, preferably 70% or less.

  Further, the scissors 1 are between the fulcrum part K and the blade tips T of the blades 2 and 3, and on the side close to the fulcrum part K, the blades 2 and 3 are in a direction orthogonal to the direction of the opening and closing operation of the blades 2 and 3. Are formed, and the holder 11 is attached to the cutting edge T side with respect to the step parts 6 and 7. Therefore, it is possible to make the blades 2 and 3 from the blade tips T to the step portions 6 parallel to the fingers while the pressing plate 5 of the fulcrum K is positioned on the back of the hand or the palm.

  The holders 11 are respectively attached at positions facing each other when the pair of blades 2 and 3 are closed, and the facing surfaces of the holder 11 are kept away from each other by a predetermined distance or more. A protruding stopper 13 is formed. Therefore, useless operation of the blades 2 and 3 can be eliminated.

  Further, the scissors 21 have the upper end surfaces 22 of the two holders 11 in the thickness W2 direction when the direction orthogonal to the operation direction of the holder 11 associated with the opening / closing operation of the blades 2 and 3 is the holder thickness W2 direction. They are on the same plane, and their lower end surfaces 23 are also on the same plane. Therefore, the hair can be cut with the upper end surface 22 or the lower end surface 23 pressed against the head. The center P of the blades 2 and 3 in the direction of the thickness W6 is attached to the position of ¼ of the thickness W2 of the holder 11 from the lower end surface 23. Therefore, when the hair is cut the same length with the upper end surface 22 pressed against the head, the length of the hair cut can be made different from the case where the lower end surface 23 is pressed against the head. For example, when it is desired to shorten the hair, the lower end surface 23 is pressed against the head to cut the hair, and when the hair is desired to be slightly longer, the upper end surface 22 is pressed against the head to cut the hair.

  The holder 11 is outsert molded so that the hole 8 is filled with resin. Therefore, it is difficult for the holder 11 to come off the blades 2 and 3.

(Other forms)
The scissors 1 and 21 in the embodiment of the present invention have been described above, but various modifications can be made without departing from the gist of the present invention. For example, the numerical values shown in the respective embodiments are examples, and other numerical values may be adopted.

  Further, the scissors 1 and 21 include a pair of blades 2 and 3 that can be rotated around the fulcrum part K, and a holder 11 having a finger insertion hole 12 into which a finger of a human hand can be inserted. In the scissors 1 and 21, the centers M and P in the height direction of the fulcrum part K are arranged so as to be shifted in the height direction with respect to the center C of the finger insertion hole 12 of the holder 11.

  Here, although the scissors 1 and 21 have the pressing plate 5 as a member of the part which comprises the fulcrum part K, the pressing plate 5 may be abbreviate | omitted. The shape of the pin 4 can be changed as appropriate. Furthermore, the hole 8 may be omitted, the circular shape may be other shapes such as a square shape, or may be a recess that does not penetrate. Furthermore, the material of the holder 11 is not limited to polyethylene resin, but may be other materials such as resin such as polypropylene resin, wood, glass, metal, and ceramic. Similarly, the blades 2 and 3 are not limited to metal, but may be other materials such as resin, wood, glass, metal, ceramic and the like. Moreover, each dimension (W1-W6, G1, L1-L8) of the scissors 1 and 21 can be changed suitably.

  Further, the scissors 1 are such that the center M in the height direction of the fulcrum portion K is 10 mm in the height direction with respect to the center C of the finger insertion hole 21 of the holder 11, and the center P of the fulcrum portion K of the scissors 21 is 9 to 11 mm. Are arranged. However, this deviation value can be changed as appropriate. The deviation is preferably 7 to 12 mm, and more preferably 9 to 11 mm.

  Further, only one holder 11 is attached to each of the blades 2 and 3 at a position 3/5 of the distance from the fulcrum part K to the cutting edge T of the blades 2 and 3 and away from the fulcrum part K in the direction of the cutting edge T. Yes. However, the attachment position of the holder 11 can be changed as appropriate. For example, the attachment position of the holder 11 may be a position that is less than 1/5 of the distance from the fulcrum part K to the cutting edge T of the blades 2 and 3 and is away from the fulcrum part K in the cutting edge T direction. Two or more holders 11 may be attached to each of the blades 2 and 3. Further, one holder 11 may be attached to one of the blades 2 and 3 and two may be attached to the other. Further, the finger insertion holes 12 and 12 of the holder 11 are arranged on the sides of the blades 2 and 3, but may be formed so as to overlap the blades 2 and 3. If it does in this way, the movable range of a finger will become wide.

  Further, the scissors 1 are between the fulcrum part K and the blade tips T of the blades 2 and 3, and on the side close to the fulcrum part K, the blades 2 and 3 are in a direction orthogonal to the direction of the opening and closing operation of the blades 2 and 3. Are formed, and the holder 11 is attached to the cutting edge side of the step parts 6 and 7. However, the stepped portions 6 and 7 may not be formed. Further, the holder 11 may be attached to the fulcrum portion K side with respect to the step portions 6 and 7 or the step portions 6 and 7.

  The holders 11 are respectively attached at positions facing each other when the pair of blades 2 and 3 are closed, and the facing surfaces of the holder 11 are kept away from each other by a predetermined distance or more. A protruding stopper 13 is formed. However, the holders 11 may be attached to positions that are not opposed to each other when the blades 2 and 3 are closed. Further, the stopper 13 can be omitted. The stopper 13 may be formed only on one of the opposing holders 11. The stopper 13 may be provided near the fulcrum part K. For example, the fulcrum part K side of the pair of blades 2 and 3 may be extended in the opposite direction, and the stopper 13 may be provided in the extended part.

  Further, the scissors 1 and 21 have the upper end surface 14 in the thickness W2 direction of the holder 11 when the direction perpendicular to the operation direction of the holder 11 accompanying the opening and closing operations of the blades 2 and 3 is the thickness W2 direction of the holder 11. 22 is on the same plane, and the lower end surfaces 15 and 23 are also on the same plane. However, the upper end surfaces 14 and 22 and the lower end surfaces 15 and 23 do not have to be on the same plane. Further, the center P of the scissors 21 in the direction of the thickness W6 of the blades 2 and 3 is attached from the lower end surface 23 to a position that is 1/4 of the thickness W2 of the holder 11. However, the center P in the thickness W6 direction of the blades 2 and 3 does not need to be attached to a position that is 1/4 of the thickness W2 of the holder 11 from the lower end surface 23. It can be appropriately changed within a range of 1/10 to 1/2 of the thickness W2 of the holder 11 from the end face 22.

  Furthermore, the holder 11 is detachable from the blades 2 and 3, and several types of holders 11 are prepared, and the distance from the center P in the thickness W6 direction of the blades 2 and 3 to the lower end surface 23 can be changed at a predetermined distance. It is good as a thing. Such a configuration can also be applied to the scissors 1.

  8 and 9, the index finger and the middle finger are inserted into the finger insertion hole 12 of the scissors 1, but the scissors 1 and 21 may be operated with the thumb and index finger, the middle finger and the ring finger, the ring finger and the little finger. . 8 and 9, the cutting edge T of the scissors 1 does not protrude from the index finger and the middle finger, but the blades 2 and 3 may protrude beyond the length of the finger to be used. However, as shown in FIGS. 8 and 9, it is preferable that the cutting edge T of the scissors 1 protrudes from the index finger and the middle finger. This is because the safety aspect of the scissors 1 and 21 and the ease of operation should be considered. The portions of the blades 2 and 3 that are outside the finger than the blade tip T cannot be controlled with the sense of the fingertip. For example, when the user cuts the hair on the back of the head, the hair of excessive length is cut. There is a fear.
