Mode for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following embodiments, a direction generally along the opening / closing direction of the blade portion will be described as the width direction of the blade portion and the cap, and a direction orthogonal to the longitudinal direction and the width direction of the blade portion will be described as the thickness direction of the blade portion and the cap.

[0010] FIGS. 1 to 4 are diagrams schematically showing an example of the scissors according to the present embodiment. As shown in FIGS. 1 and 2, the scissors 1 according to this embodiment includes a scissor body 10 and a cap 20 that houses the blade portions (12, 17) of the scissor body 10 in a closed state. With such a configuration, the blade portions (12, 17) can be protected by the cap 20. The scissors 1 includes a blade sharpening portion 28 provided so as to be exposed at a first end portion (26) on one side in the longitudinal direction of the cap 20. With such a configuration, it is not necessary to carry a sharpener or the like separately from the scissors 1, and the blade portions (12, 17) of the scissor body 10 can be sharpened using the blade sharpening portion 28 of the cap 20 detached from the scissor body 10. An example of the specific configurations of the cap 20 and the blade sharpening portion 28 will be described later.

[0011] Although details will be described later, as shown in FIGS. 3(b) and 4(c), the scissor body 10 includes a moving blade body 11 having a moving blade side blade portion (moving blade side blade portion) 12 and a moving blade side handle portion (moving blade side handle portion) 14 that constitute the blade portions (12, 17), and a stationary blade body 16 having a stationary blade side blade portion (stationary blade side blade portion) 17 and a stationary blade side handle portion (stationary blade side handle portion) 19 that constitute the blade portions (12, 17), and is separable. With such a configuration, the scissor body 10 can be separated into the moving blade body 11 and the stationary blade body 16, and the respective blade portions (moving blade side blade portion 12 and stationary blade side blade portion 17) can be sharpened using the blade sharpening portion 28 of the cap 20, thereby improving the sharpening operability. This scissor body 10 is a so-called Western-style scissor in which the moving blade body 11 and the stationary blade body 16 are overlapped in a cross shape (X shape) and are rotatable around connecting portions (13, 18) serving as fulcrums.

[0012] The connecting portions (13, 18) include a shaft portion 18 provided on one of the moving blade body 11 and the stationary blade body 16 and serving as a fulcrum, and a bearing portion 13 provided on the other and detachably engaged with the shaft portion 18. In the illustrated example, an example is shown in which the bearing portion 13 is provided on the moving blade body 11 and the shaft portion 18 is provided on the stationary blade body 16, but these may be provided on the opposite side. The shaft portion 18 is provided at the base end portion, which is the end portion on the stationary blade handle portion 19 side in the longitudinal direction of the stationary blade side blade portion 17, so as to protrude toward the moving blade side blade portion 12. A pair of locking protrusions 18a, 18a protruding outward in the radial direction are provided on this shaft portion 18. These pair of locking protrusions 18a, 18a are provided at positions equally spaced in the circumferential direction. The bearing portion 13 is formed in a hole shape by penetrating the base end portion, which is the end portion on the moving blade handle portion 14 side in the longitudinal direction of the moving blade side blade portion 12, in the thickness direction. In this bearing portion 13, a pair of insertion / removal recesses 13a, 13a are provided which open on the inner circumferential side of the bearing hole portion having an inner diameter corresponding to the outer diameter of the columnar portion of the shaft portion 18 and into which the pair of locking protrusions 18a, 18a can be inserted and removed respectively.

[0013] The pair of locking protrusions 18a, 18a and the pair of insertion / removal recesses 13a, 13a are configured to be insertable and removable when the moving blade body 11 and the stationary blade body 16 are opened at a predetermined angle (for example, about 80 degrees to 100 degrees). The pair of locking protrusions 18a, 18a are locked to the hole peripheral edge portion of the bearing hole portion of the bearing portion 13 from the state where the moving blade body 11 and the stationary blade body 16 are closed to the state where they are opened at the above-mentioned predetermined angle, and the moving blade body 11 and the stationary blade body 16 are made inseparable. That is, when the moving blade body 11 and the stationary blade body 16 are opened and closed around the fulcrum and used as scissors (cutting (shearing)), they can be used without the moving blade body 11 and the stationary blade body 16 separating. On the other hand, when the moving blade body 11 and the stationary blade body 16 are opened at a predetermined angle, they can be displaced in the thickness direction and separated from each other. The configuration for making the moving blade body 11 and the stationary blade body 16 separable is not limited to the configuration as shown in the figure example, and may be various other configurations. Also, an appropriate tightening mechanism may be provided on the shaft portion 18.

[0014] In this embodiment, the scissors body 10 is a multi-functional scissors having functions other than the scissor function. The scissors body 10 is a multi-functional cooking scissors having a plurality of functions that can be used when cooking in the kitchen or outdoors such as camping. With such a configuration, it can be suitably used when cooking in the kitchen or outdoors such as camping. Specifically, the scissors body 10 has a peeler function, a scale-removing function, a shell-breaking function, and a crown-removing function. As functions other than the scissor function provided in the scissors body 10, at least one of these may be provided, or other functions, for example, a screwdriver function, a wire cutting function, etc. may be provided according to the application, etc.

[0015] When viewed in the thickness direction, the moving blade side edge portion 12 and the stationary blade side edge portion 17 are each formed in a tapered shape from the base end portion toward the tip end portion. On one side in the width direction of these moving blade side edge portion 12 and stationary blade side edge portion 17, an appropriate blade line is formed so as to be able to cut the object to be cut. On the peak side opposite to the blade line in the width direction of the moving blade side edge portion 12, a scale-removing portion 12a constituting the scale-removing function is formed. In the illustrated example, the scale-removing portion 12a is formed in a sawtooth shape (concave-convex shape) in which the valley portion is in a concave curved shape and the mountain portion is in a sharp shape, and is provided substantially over the entire longitudinal direction of the peak portion of the moving blade side edge portion 12. On the peak side opposite to the blade line in the width direction of the stationary blade side edge portion 17, a peeler hole portion 17a constituting the peeler function is formed. In the illustrated example, the peeler hole portion 17a is formed in a long hole shape so as to extend in the longitudinal direction of the stationary blade side edge portion 17 in substantially the half portion on the base end side of the stationary blade side edge portion 17. A peeler blade is formed on one side edge portion in the width direction of this peeler hole portion 17a (see Fig. 3(b)).

[0016] In this embodiment, the moving blade side handle portion 14 and the stationary blade side handle portion 19 are made of metal integrally formed with the moving blade side edge portion 12 and the stationary blade side edge portion 17 respectively. That is, the moving blade side handle portion 14 and the stationary blade side handle portion 19 do not have a resin or the like that covers the base portion integrally formed with the moving blade side edge portion 12 and the stationary blade side edge portion 17 respectively, and are made of metal throughout. When viewed in the thickness direction, the moving blade side handle portion 14 and the stationary blade side handle portion 19 have a generally line-symmetric outer contour shape with the width direction center line of the scissors body 10 in the closed state as the axis of symmetry. In the illustrated example, when viewed in the thickness direction, the outer contour shapes of the moving blade side handle portion 14 and the stationary blade side handle portion 19 are each formed in a substantially trapezoidal shape. That is, the outer contour shape when viewed in the thickness direction of the entire handle portion formed with the moving blade side handle portion 14 and the stationary blade side handle portion 19 in the closed state is formed in a substantially hexagonal shape.

[0017] At the opposing portions of the moving blade side handle portion 14 and the stationary blade side handle portion 19 in the closed state, shell-breaking portions 14a and 19a that constitute the shell-breaking function are respectively provided. In the illustrated example, each of the shell-breaking portions 14a and 19a is formed in a triangular mountain-shaped saw blade shape (concave-convex shape) and is partially provided on each blade portion side of the moving blade side handle portion 14 and the stationary blade side handle portion 19. A plug-pulling portion 15 that constitutes a plug-pulling function is provided on the moving blade side handle portion 14. In the illustrated example, the plug-pulling portion 15 is formed in a notch shape so as to form a crown support portion and a hook portion at an end portion of the moving blade side handle portion 14 on a side different from the moving blade side blade portion 12 side. In addition, finger insertion holes 14b, 14c, and 19b into which fingers are inserted are provided in the moving blade side handle portion 14 and the stationary blade side handle portion 19.

[0018] On the moving blade side handle portion 14, a first finger insertion hole 14b on the moving blade side blade portion 12 side and a second finger insertion hole 14c on a side different from the moving blade side blade portion 12 side are provided. With such a configuration, depending on the hand size, work, etc., a finger (thumb) can be selectively inserted into either the first finger insertion hole 14b or the second finger insertion hole 14c, and the usability can be improved. The first finger insertion hole 14b and the second finger insertion hole 14c may both be capable of inserting the thumb of an adult male. In the illustrated example, when viewed in the thickness direction (penetration direction), an example is shown in which the first finger insertion hole 14b is formed in a rhombic hole shape and the second finger insertion hole 14c is formed in a trapezoidal hole shape, but it is not limited to such an example. The finger insertion hole 19b of the stationary blade side handle portion 19 may be capable of inserting four fingers other than the thumb of an adult male. In the illustrated example, the finger insertion hole 19b is shown as being formed in a trapezoidal hole shape corresponding to the outer shape of the stationary blade side handle portion 19 when viewed in the thickness direction (penetration direction), but is not limited to such an example.

[0019] The scissors body 10 may be made of an appropriate metal such as stainless steel, and may also be appropriately coated such as with a fluorine coating. Note that the scissors body 10 is not limited to examples having functions other than the above-described scissor function, and may have a configuration without functions other than the scissor function. Also, in the illustrated example, the right-handed scissors body 10 is exemplified, but appropriate modifications may be made to make it left-handed or ambidextrous.

[0020] As shown in FIG. 2, the cap 20 is formed so as to partition a housing space 21 for housing the blade portions (the moving blade side blade portion 12 and the stationary blade side blade portion 17). The cap 20 has a shape generally corresponding to the outer shapes of the housing space 21 and the outer shapes of the moving blade side blade portion 12 and the stationary blade side blade portion 17 in a closed state. A receiving port 22 is provided on the other side in the longitudinal direction, which is different from the tip side on one side in the longitudinal direction, and it has a substantially square tube shape with a bottom having the tip side as the bottom. As shown in FIGS. 1 and 2, the cap 20 is formed such that the width dimension decreases as it goes toward the tip side (see also FIG. 4(b)). The other side surface in the width direction of the cap 20 is formed to be substantially flat over substantially the entire surface so as to be placeable on a workbench such as a desk. The other end surface in the longitudinal direction on the receiving port 22 side of the cap 20 is formed to be inclined with respect to the other side surface in the width direction so as to become the tip side in the longitudinal direction as it goes toward one side in the width direction. At the receiving port 22 of the cap 20, an engaging portion 23 with which the shaft portion 18 of the scissor body 10 engages is formed in a notch shape. This engaging portion 23 is formed in a notch shape on the other end surface in the longitudinal direction of the cap 20. By receiving the shaft portion 18 in this engaging portion 23, the detachment of the cap 20 from the scissor body 10 may be suppressed. The engaging portion for suppressing the detachment of the cap 20 from the scissor body 10 is not limited to such a configuration, and may be configured in various other ways.

[0021] A through hole 24 is formed in the cylindrical wall portion of the cap 20. In the illustrated example, an example is shown in which a plurality (six in the illustrated example) of through holes 24 are provided at intervals (equally spaced in the illustrated example) in the longitudinal direction of the cap 20. Further, these through holes 24 are formed in a series from the wall portion partitioning one side in the thickness direction of the cap 20 to the wall portion partitioning one side in the width direction. These through holes 24 are formed so as to generally extend in the width direction when viewed in the thickness direction. As shown in FIG. 4(b), these through holes 24 are formed so as to extend obliquely with respect to the other side surface in the width direction of the cap 20. These through holes 24 are formed so as to open toward one side in the width direction when viewed in the thickness direction. The hole edge portions on the other side in the width direction, which are on the bottom side when viewed in the thickness direction of these through holes 24, are each formed in a substantially flat plane shape and are formed substantially parallel to the other side surface in the width direction of the cap 20. The hole edge portions on both side edges when viewed in the thickness direction of these through holes 24 are formed substantially parallel to the other end surface in the longitudinal direction on the receiving port 22 side of the cap 20. In the illustrated example, an example is shown in which the angle (tilt angle) formed between the other side surface in the width direction of the cap 20 and the hole edge portions on both sides of the through hole 24 is about 50 degrees, but it is not limited to such an angle.

[0022] On the wall portion that partitions the other side in the thickness direction of the cap 20, a magnet 25 is provided. With such a configuration, in a state where the moving blade side blade portion 12 and the stationary blade side blade portion 17 of the scissors body 10 are accommodated in the cap 20, the scissors 1 can be attached (adsorbed) to an attachment target including a ferromagnetic material such as a refrigerator by the magnet 25. In the illustrated example, an example is shown in which a plurality (three in the illustrated example) of magnets 25 are provided at intervals in the longitudinal direction of the cap 20. Further, in the illustrated example, these magnets 25 are configured to be exposed also on the inner surface side of the cap 20, but may be configured to be exposed only on the outer surface side. Further, these magnets 25 may function as an adsorption portion that suppresses the cap 20 from falling off with respect to the scissors body 10.

[0023] In the present embodiment, as shown in FIG. 1, the blade sharpening portion 28 is provided on the tip side, which is one side in the longitudinal direction, of the accommodation space 21 in the cap 20. With such a configuration, when sharpening the blade portions (the moving blade side blade portion 12 and the stationary blade side blade portion 17), the dimension along the cap width direction on the other side in the longitudinal direction of the cap 20, which is the side to be gripped, becomes larger than that on the tip side, so it becomes easier to grip. Further, compared with a configuration in which the blade sharpening portion is provided on the cylindrical wall portion that partitions the accommodation space 21 in the cap 20, the blade sharpening portion 28 can be stably provided in the solid portion on the tip side.

[0024] As shown in FIG. 4(b), the blade sharpening portion 28 is provided with a blade receiving groove portion 29 that opens to one side in the width direction and is V-shaped when viewed in the thickness direction. With such a configuration, by inserting the blade portions (the moving blade side blade portion 12 and the stationary blade side blade portion 17) into the blade receiving groove portion 28 and relatively moving the blade portions (the moving blade side blade portion 12 and the stationary blade side blade portion 17) in the thickness direction of the cap 20 with respect to the cap 20, the blade portions (the moving blade side blade portion 12 and the stationary blade side blade portion 17) can be sharpened without being displaced in the longitudinal direction of the cap 20, and the sharpening operability can be improved. As a result, when sharpening the blade portions (the moving blade side blade portion 12 and the stationary blade side blade portion 17), it becomes difficult for the blade portions (the moving blade side blade portion 12 and the stationary blade side blade portion 17) to contact the cap 20 around the blade sharpening portion 28, and damage to the cap 20 and the like can be suppressed.

[0025] The edge grinding part 28 is provided in a recess 27 that opens on one side in the width direction and penetrates in the thickness direction at the tip part 26 of the cap 20. With such a configuration, compared with a configuration in which the edge grinding part 28 is provided in an attached manner on the side part or the like of the cap 20, it becomes difficult for the edge grinding part 28 to contact peripheral members, and damage or the like of the edge grinding part 28 can be suppressed. As shown in FIGS. 4(a) and 4(b), in the recess 27, the depth dimension D along the width direction of the cap 20 is larger than the width dimension W along the longitudinal direction of the cap 20. With such a configuration, while the edge grinding part 28 is provided in the solid part of the tip part 26 of the cap 20, the dimension along the longitudinal direction of the cap 20 can be reduced.

[0026] Specifically, the recess 27 is formed to open on one side in the width direction of the cap 20 and penetrate in the thickness direction of the cap 20 in the solid part of the tip part 26 on the tip side of the accommodation space 21. The recess 27 is formed to generally extend in the width direction when viewed in the thickness direction of the cap 20. This recess 27 is formed to extend in an inclined manner with respect to the other side surface in the width direction of the cap 20, as shown in FIG. 4(b), similar to the above-described through hole 24. Note that FIG. 4(a) shows a state in which the cap 20 is viewed along the inclination direction of the recess 27 and the through hole 24. The bottom part that partitions the bottom side of this recess 27 is formed in substantially the same plane as the hole edge part on the bottom side of the through hole 24 and is formed substantially parallel to the other side surface in the width direction of the cap 20. Also, both side parts that partition both sides in the width direction (longitudinal direction of the cap 20) of the recess 27 are formed substantially parallel to the hole edge parts on both sides of the through hole 24. Further, this recess 27 is formed such that the interval between it and the through hole 24 located at the most tip side is approximately the same as the interval between the through holes 24. With such a configuration, a design unity between the recess 27 and the through hole 24 can be achieved, and the appearance can be improved.

[0027] The width dimension W of this recess 27 is a dimension along a direction orthogonal to the above-mentioned inclined direction and the thickness direction of the cap 20. The depth dimension D of the recess 27 is the dimension of the portion where it is the smallest in the inclined direction which is the depth direction of the recess 27. In the illustrated example, the depth dimension D of the recess 27 is defined as the dimension from the bottom side edge of the tip side portion of the cap 20 among the both side portions partitioning both sides in the width direction of the recess 27 to the opening side edge. These width dimension W and depth dimension D of the recess 27 may be appropriate dimensions from the viewpoint of providing the blade sharpening portion 28 in the recess 27 and suppressing the contact between the blade sharpening portion 28 and the peripheral members. Also, the depth dimension D of the recess 27 may be about 1.2 times to 2 times the width dimension W of the recess 27. In the illustrated example, an example of about 1.5 times is shown. Note that instead of making the depth dimension D of the recess 27 larger than the width dimension W of the recess 27, it may be made about the same or smaller. The shape of this recess 27 and the above-mentioned through hole 24 is not limited to the shape as in the illustrated example, and may be various other shapes.

[0028] As shown in FIG. 4(b), the blade receiving groove portion 29 is provided such that the groove bottom thereof is located on the other side in the width direction rather than the center in the width direction at the tip portion 26 of the cap 20. With such a configuration, since the groove bottom of the blade receiving groove portion 29 is at a relatively deep position in the width direction of the cap 20, when the cap 20 is placed on a workbench such as a desk and held so that the blade receiving groove portion 29 opens upward and the blade portions (the moving blade side blade portion 12 and the stationary blade side blade portion 17) are sharpened, it becomes difficult for the cap 20 to rotate around the axis along the longitudinal direction, and it can be sharpened stably.

[0029] Specifically, the blade receiving groove portion 29 is formed such that the groove width dimension increases from the groove bottom toward the opening side when viewed in the thickness direction of the cap 20. In the present embodiment, the blade sharpening portion 28 is composed of a first groove wall member that defines one groove wall on one side in the groove width direction of the blade receiving groove portion 29 and a second groove wall member that defines the other groove wall on the other side in the groove width direction of the blade receiving groove portion 29. With such a configuration, for example, compared with a configuration in which a groove portion is formed in a single member, the groove bottom of the blade receiving groove portion 29 can be made into a sharp shape corresponding to the blade lines of the moving blade side blade portion 12 and the stationary blade side blade portion 17 without forming a roundness (concave curved surface) or the like at the groove bottom of the blade receiving groove portion 29. In the illustrated example, an example is shown in which the first groove wall member and the second groove wall member are arranged so as to overlap each other in the thickness direction of the cap 20 such that one side surface of the first groove wall member and one side surface of the second groove wall member intersect (see FIG. 4(a)). Note that, instead of the mode in which the blade sharpening portion 28 is configured by the first groove wall member and the second groove wall member as described above, a mode in which a groove portion (blade receiving groove portion 29) is formed in a single member may also be adopted.

[0030] The groove bottom of the blade receiving groove portion 29 is provided such that, when viewed in the thickness direction of the cap 20, it is located on the virtual line passing through the inside of the tip portion 26 of the cap 20, which is orthogonal to the other side surface in the width direction of the cap 20 and in contact with the groove bottom, and is located on the other side surface in the width direction of the cap 20 from the center of this virtual line. In the illustrated example, the blade receiving groove portion 29 is provided such that its groove bottom is located generally at the center although it is on the other side surface in the width direction of the cap 20 from the center of the virtual line. The position of the groove bottom of the blade receiving groove portion 29 is not limited to such a position, and further, it may be provided so as to be located on one side in the width direction from the center in the width direction at the tip portion 26 of the cap 20.

[0031] The blade receiving groove portion 29 is formed such that the opening edge portion on one side in the width direction of the recess 27 (the other side in the longitudinal direction of the cap 20) is flush with the groove wall on one side in the groove width direction (the other side in the longitudinal direction of the cap 20). In other words, the opening edge portion on one side in the width direction of the recess 27 is formed so as to be in contact with a virtual plane that is flush with the groove wall on one side in the groove width direction of the blade receiving groove portion 29. With such a configuration, as shown by the two-dot chain line in FIG. 4(b), the surfaces (the back sides) of the moving blade side blade portion 12 and the stationary blade side blade portion 17 that face each other are made to follow along one side groove wall and abut against the opening edge portion on one side in the width direction of the recess 27, whereby it is possible to suppress the back sides of the moving blade side blade portion 12 and the stationary blade side blade portion 17 from being excessively ground.

[0032] One side groove wall of this blade receiving groove portion 29 may be formed perpendicular to the other side surface in the width direction of the cap 20 when viewed in the thickness direction. However, in the illustrated example, it is formed to be slightly inclined so as to become the tip side of the cap 20 as it goes from the groove bottom side toward the groove opening side. As shown in FIG. 4(c), the inclination angle of one side groove wall of this blade receiving groove portion 29 may be set to an appropriate angle such that the blade portions (the moving blade side blade portion 12 and the stationary blade side blade portion 17) of the scissors body 10 held with the other hand are easily ground in a state where the other side surface in the width direction of the cap 20 is abutted against a workbench such as a desk and the cap 20 is held with one hand. The angle formed between one side groove wall of the blade receiving groove portion 29 and the other side surface in the width direction of the cap 20 when viewed in the thickness direction may be, for example, about 65 degrees to 80 degrees. In the illustrated example, an example where it is about 75 degrees is shown.

[0033] The angle formed between both groove walls of this blade receiving groove portion 29 may be an angle corresponding to the blade lines of the moving blade side blade portion 12 and the stationary blade side blade portion 17, and may be, for example, about 30 degrees to 50 degrees. In the illustrated example, an example where it is about 45 degrees is shown. The above-described blade grinding portion 28 (the first groove wall member and the second groove wall member) may be provided on the cap 20 so as to be replaceable. Further, the blade grinding portion 28 (the first groove wall member and the second groove wall member) may be made of a metal having high hardness and high wear resistance such as tungsten. Further, the cap 20 may be made of a synthetic resin having high wear resistance such as nylon 66.

[0034] When sharpening the blade portions (the moving blade side blade portion 12 and the stationary blade side blade portion 17) of the scissors body 10 using the cap 20 configured as described above, as shown in FIG. 4(c), the scissors body 10 may be separated into the moving blade body 11 and the stationary blade body 16 (see FIG. 3), and these blade portions (the moving blade side blade portion 12 and the stationary blade side blade portion 17) may be sequentially sharpened. At this time, as shown in FIG. 4(b), with the back side of the blade portion (the moving blade side blade portion 12 and the stationary blade side blade portion 17) along one groove wall of the blade receiving groove portion 29 and in contact with the opening edge portion on one side in the width direction of the recess 27, the blade portion (the moving blade side blade portion 12 and the stationary blade side blade portion 17) may be sharpened by displacing it in its longitudinal direction.

[0035] In addition, in the above example, an example where the scissors body 10 is separable into the moving blade body 11 and the stationary blade body 16 is shown, but it may also be non-separable. Also, in the above example, an example where the blade sharpening portion 28 is provided so as to be located within the recess 27 provided in the cap 20 is shown. However, instead of such a mode, the blade sharpening portion 28 may be provided in an attached manner on the side portion or the like of the cap 20. Also, in the above example, an example where the blade sharpening portion 28 is provided at the tip portion 26 on the tip side of the accommodation space 21 of the cap 20 is shown.
