Definitions

  • the present invention relates to such versatile scissors as applicable not only on papers, textiles, plants and hairs, but also for clipping metallic wires.
  • the rotated blade causes rotational force resulting in urging the object matter off the scissors due to lack of blade bite.
  • both the cross point and the scissor handles have been considerably deviated from the extension line of scissors blades, or the blades have been curved inwards for clipping plants.
  • such devices have been inconvenient to operate because of the deviation of blades from the operational direction.
  • the sliding surfaces of the scissors blade are provided adjacent to the pivot. Therefore, when the surfaces have been worn, the scissors themselves have had to be sharpened, which requires proficient skills. Furthermore, since the sliding surfaces are considerably great, the wear of the surface has required replacement of the scissors themselves, resulting in low efficiency.
  • the purpose of the present invention is, by means of overcoming any drawbacks in the conventional scissors, to provide such scissors able to tightly bite any matter, however hard, thin or flexible it may be, resulting in accurate clipping.
  • the present invention provides hairdressing scissors with smooth workability, eliminating abraded wear around the pivot and slippage of fine hairs from the scissors.
  • Such hairdressing scissors according to the present invention can be easily repaired, leaving no rattling.
  • the scissors of the present invention comprise a first scissor blade having a clipping blade along the lower edge thereof, a second scissor blade having a clipping blade along the upper edge thereof, a first and second handle portion provided respectively at the base portions of the scissor blades, and a pivot supporting the scissor blades rotatably, the axis of the pivot being disposed above the blade edge of the second blade, and bearing portions into which said pivot is inserted, being projectingly provided at the upper edges of the first and second blades.
  • the first scissor blade will draw the matter to be clipped inwards, when rotating, to make the blade bite the matter firmly, leading to easy clipping.
  • the perpendicular distance of the pivot point 0 from the blade E1 is the same as the perpendicular distance of point e from blade E1, the point e on blade E2 will initially move perpendicularly towards blade E1. Therefore, the perpendicular distance of the pivot point 0 from the blade E1 should preferably be greater than the perpendicular distance from the blade point e to the blade E1.
  • Hairdressing scissors of the present invention are provided with a bearing portion projectingly provided at the edges of the first and second scissor blades, respectively, and a sliding surface around the pivot. Moreover, since the sliding surface is detachable, the scissors are easy to repair.
  • the sliding surface may be constituted with a slippery material which will make clipping work smooth.
  • Fig. 1 is the front view of the 1st embodiment of the present invention.
  • Fig. 2 is the front view of the 2nd embodiment of the present invention.
  • Fig. 3 is the front view of the 3rd embodiment of the present invention.
  • Fig. 4 is the front view of the 4th embodiment of the present invention.
  • Fig. 5 is the partial front view depicting the main portion of the 4th embodiment.
  • Fig. 6 is the front view of the 5th embodiment of the present invention.
  • Fig. 7 is the exploded front view of the 5th embodiment.
  • Fig. 8 is the operational front view of the 5th embodiment.
  • Fig. 9 is the partial section around the pivot of the 5th embodiment .
  • Fig. 10 is the explanatory diagram depicting operations of conventional scissors.
  • Fig. 11 and 12 is the explanatory diagram depicting operations of scissors according to the present invention.
  • a first scissor blade 1 and a second scissor blade 2 are formed as thin plates, at the lower edge portion of the first scissor blade 1, and at the upper edge portion of the second scissor blade 2 are formed the clipping blades 3 and 4, respectively.
  • the first blade 1 and second blade 2 extend to be a first handle 5 and a second handle 6 at the base portions.
  • bearing portions 7, 8 are projectingly provided, respectively, and a pivot 9 is inserted through the holes provided at both bearing portions to pivotally support the blades 1 and 2.
  • ring-like portions 10 are provided at the edges of the first and second handles for receiving fingers, the portions 10 being covered with plastic rings 11 to protect fingers.
  • Matter to be clipped is placed between the blades 3 and 4 which are opened. Then, the first scissor blade 1 is returned constituting a clipping portion at the mating area between the blade 3 and 4 with the matter being bit firmly. Namely, the blade 3 moves right downward relative to blade 4 at the clipping area because the center of the pivot of the first scissor blade 1 is disposed above the blade 4 of the second scissor blade 2. Consequently, a drawing force is applied upon the matter inwards.
  • a blade 23 is formed at the lower edge of a first scissor blade 21, and a blade 24 is farmed at the upper edge of a second scissor blade 22, said blades 21 and 22 having wedge-like sections with proper thicknesses, respectively.
  • bearing portions 27 and 28 each of which has a pivot hole are projectingly provided, respectively. Through these holes, a pivot 29 is inserted to receive the first and second scissor blades 21 and 22 rotatably.
  • a first handle 25 and a second handle 26 are integrally provided, respectively, the handles being curved outwards.
  • these handles 25 and 26 may be formed as elongated elliptic rings.
  • a gripping force can then be easily applied upon the handles 24 and 25, because they are curved outwards, which fact is obviously more suitable for hard matter, such as a plant branch or the like, than using fingers only.
  • the wedge-like sections will support this purpose for harder and fatter matter as well.
  • clipping is performed by drawing the matter inwards, without slipping it out.
  • a first scissor blade 31 and a second scissor blade 32 are formed thin, and along the lower edge of said blade 31 and the upper edge of said blade 32 are formed the clipping blades, respectively.
  • either of such clipping blades is formed as saw-like teeth.
  • a first handle 35 and a second handle 36 are integrally provided at the base portion of said blades 31 and 32, respectively.
  • bearing portions 37 and 38 are projectingly provided at the upper portions of the base portions of the blade 31 and 32, respectively, the bearing portions having pivot holes to be inserted through with a pivot 39 to pivotally support the blades 31 and 32.
  • the saw-like teeth will then grip the matter to be clipped, followed by sliding of the blade 31 to draw the matter inwards, relative to the blade 32. Therefore, the matter will not slip off.
  • the long shaft 50 is a pipe, made of a light and tenacious material, such as FRP (fortified resin plastics).
  • a pair of scissors 40 and operation device 60 are provided at each end of said shaft 50, respectively.
  • clipping blades are formed at the lower edge of a first thin scissor blade 41, and at the upper edge of a second thin scissor blade 42, respectively.
  • the first plate 43 and the second plate 44 are provided at the base portions of the blades 41 and 42, respectively.
  • These blades 41 and 42 are rotatably supported by a pivot 45, and a spring 46 will bias the blades 41 and 42 to open.
  • a bearing portion 47 having a pivot hole is projectingly provided at the upper portion of the base portion of the blade 42, and the pivot 45 is inserted through the pivot hole of the bearing portion 47 to rotatably support the 1st blade 41 and 2nd blade 42.
  • the first plate 43 is formed nearly perpendicular to the first scissor blade 41, and second plate 44 is formed slightly declined to the second scissor blade 42, with the edge of the handle 44 being fixed to one end of the shaft 50.
  • the spring 46 is a resilient spring with the twist portion thereof being disposed at the base portion of said second scissor blade 42, and with one end and the end thereof fixed to said first plate 43 and to said second plate 44, respectively, resulting in biasing said first scissor blades 41 and 42 to open each other.
  • the operation device 60 comprises a holder 61, having a guide groove 64, a grip 62 having the guides 65 on both sides, and a wire 63 connecting the grip 62 with the top of the first plate 43.
  • the surface of the grip 62 facing the long shaft 50 is formed like a wave with the connecting wire 63 secured at the center thereof.
  • the wire 63 is connected to the first plate 43 through the long shaft 50.
  • the wire may be made of steel or piano wire.
  • the first plate 43 rotates around the pivot 45 due to draught from the connecting wire 63 resulting in crossing the first scissor blade 41 and second blade 42 each other to clip the matter.
  • the blades will clip the matter by drawing it in, without urging it off.
  • the spring 46 makes the 1st plate 43 and 2nd plate 44 open for another clipping.
  • this embodiment relates to hairdressing scissors.
  • a blade 71a is formed at the left lower edge of the 1st scissor blade 71, and in Fig. 7b a blade 72a, at the right upper edge of the 2nd scissor blade 72, respectively.
  • a disk-like bearing portion 71b is projectingly provided at the right upper edge apart from the center of said 1st scissor blade 71, as well as another disk-like bearing portion 72b, at the left upper edge from the center of the 2nd scissor blade 72, respectively, with pivot holes 71c and 72c being bored at each center of the bearing portions 71b and 72b.
  • a pivot 73 is inserted through the holes 71c and 72c to support the first scissor blade 71 and second blade 72, rotatably.
  • the pivot 73 comprises a male screw 73a with convex section and a female screw 73b with concave section, both of which are clamped while holding and tighten the bearing portions 71b and 72b.
  • the portions 71b and 72b slide each other, constituting a slide surface 74, to make the blades 71a and 72b rub each other for clipping.
  • a sliding member 75 made of the same material as the scissors. Materials with low friction coefficient, such as ceramics, may be used as the sliding member 75.
  • the detachable sliding member 75 can be replaced leading to elimination of such rattling.
  • stable clipping can be attained because the diameter of the pivot 73 is considerably large, and the sliding surface 74 is adjacent to the pivot 73.
  • the present invention clips matter without it sliding off, since the pivot is positioned upward in order to apply a force upon the 1st scissor blade, toward the pivot.
  • handles are disposed at the elongated positions from the scissor blades, comfort and workability are upgraded during clipping.
  • the detachably sliding member is applied over the rubbing surface.
  • the detachable member may be made of low friction materials resulting in further smooth clipping operation.
