The specific embodiment
Fig. 1 has shown the knife sharpener of first embodiment to Fig. 3 A and 3B.This knife sharpener comprises shell 2.Shell 2 forms the casing shape of cuboid, yet a whole end face of shell 2 and a whole side are all opened wide.
When inner casing 4 was placed in the shell 2, the tip of side wall portion 6 was positioned on the openend side of shell 2.Place, tip at side wall portion 6 is formed with outstanding toward each other projection 10 and 10.The gap that is formed between projection 10 and 10 defines a slit 12.When inner casing 4 stretched out from shell 2, slit 12 holds will be by the cutter of sharpening, and cutter can move along the length direction of blade like this.The length direction of blade is consistent with the width of side wall portion 6, or consistent with the longitudinal direction of slit 12.
What place inner casing 4 is sharpening parts 14, and as shown in Figure 4, these sharpening parts 14 form by crooked metal sheet material 16.Metallic sheet material 16 comprises the rectangular base portion 18 that is positioned at its middle part, and two band portions 20 of extending from each end of base portion 18.Gap between the band portion 20 of base portion 18 each end is substantially equal to the width of band portion 20.Four band portions 20 have axle parallel to each other.Band portion 20 alternately forms along its width at the two ends of base portion 18.
Each band portion 20 all has elasticity.On the one side of each band portion 20, form lapped face 22.Abrasive grains with suitable abrasive particle diameter disperses to be bonded on the lapped face 22, makes the surface roughness of lapped face be equivalent to for example oilstone of 300 granularities, promptly thick oilstone.Though the material of abrasive particle is not particularly limited, consider that its high strength is preferably diamond or titanium nitride.
Refer again to Fig. 1 and Fig. 3 A and 3B, in order to make sharpening parts 14 by metallic sheet material 16, with metallic sheet material 16 along its pars intermedia bending longitudinally.
More specifically, the base portion 18 of metallic sheet material 16 is bent to and makes lapped face 22 towards the outside, and is molded into semicircle shape, is connected to the curved face part 8 of inner casing 4 in this semicircle.With the root of the continuous band portion 20 of base portion 18 along the direction bending identical with the bending direction of base portion 18, thereby make the band portion 20 of extending intersect as being engaged with each other together mutually from base portion 18 two ends.
The sharpening parts of being made by metallic sheet material 16 14 are placed in the inner casing 4, wherein are the state of the curved face part 8 that is connected to inner casing 4 in the base portion 18.Band portion 20 is staggered the extension between the side wall portion 6 of inner casing 4, and the tip of band portion 20 is contacting near projection 10 root places with the inner wall surface of side wall portion 6.Because four band portions 20 are intersected with each other as being engaged with each other, so they are along the alternately arrangement of longitudinal direction of the width or the slit 12 of side wall portion 6, and close on the location each other.
In sharpening parts 14, be included in the tip of part in the band portion 20 (below be referred to as expansion portion) and launch from the crosspoint to band portion 20, form V-type sharpening slot 24.Expansion portion opens towards slit 12, and the opening of sharpening slot 24 is positioned near the slit 12.Sharpening slot 24 stretches along slit 12, and lapped face 22 has formed two sides of sharpening slot 24.
Because the tip of band portion 20 contact with the inner wall surface of inner casing 4, thus the Breadth Maximum of sharpening slot 24 openings by between the inner wall surface apart from determining, and greater than the width of slit 12.When knife sharpener did not use, the angle of the crossing between the band portion 20 (also being referred to as the default angle of the crossing hereinafter) was by the distance decision between the inner wall surface of inner casing 4.
In shell 2, the block 26 that is formed from a resin is positioned at the other end side of shell.Block 26 is supporting inner casing 4 and sharpening parts 14, makes them rotatable.
Particularly, block 26 is a column type, the curved base 18 of sharpening parts 14 and the crooked root of band portion 20 all with the external peripheral surface sliding-contact of block 26.As shown in Figure 2, block 26 is fixed on the sidewall of shell 2 by screw 28, and block 26 also comprises flange portion 30 at an end of screw 28 sides.Flange portion 30 is positioned between the sidewall of inner casing 4 and shell 2, therefore guarantees to exist a space betwixt.Leaf spring 32 is arranged in this space, and it presses inner casing 4 on the sidewall that leans against shell 2, and is relative with another sidewall.
In Fig. 3, Reference numeral 34 expressions one dismountable stopper.Stopper 34 is between shell 2 and inner casing 4.The two ends of stopper 34 are all hinged with shell 2 and inner casing 4.
To introduce the method for above-mentioned knife sharpener of using below to tool sharpening.
For using knife sharpener, inner casing 4 at first will rotate it is stretched out from shell 2.Shown in Fig. 3 B, inner casing 4 is brought to stand up position, makes slit 12 be positioned at upside.In this point, inner casing 4 is supported by stopper 34, unexpectedly falls to prevent inner casing 4.Then, user one holds shell 2, and the another hand is caught cutter.Subsequently, when the user is pressed against sharpening slot 24 on by slit 12 blade of cutter, move around cutter several times along the edge length direction, thus the sharpening blade.
In the sharpening process, when the blade holddown belt portion 20 of cutter, shown in Fig. 5 A, band portion 20 strains, and bend to concave shape with respect to the edegewise of cutter.In other words, because the pressure of cutter, the angle of the crossing θ between the band portion 20 increases and above the default angle of the crossing that inner wall surface determined by inner casing 4, wherein the angle of the crossing θ between the band portion 20 is corresponding to the drift angle of sharpening slot.This is because the root of band portion 20 is fixed in the inner casing 4, and the tip of band portion 20 contacts with the inner wall surface of inner casing 4.
Angle of the crossing θ surpasses under the state of the default angle of the crossing as mentioned above therein, if blade moves in sharpening slot 24, then final meeting forms the corresponding final groove with protruding side of curved shape with band portion 20 on blade, and protruding side has involute shape substantially.Fig. 5 B summary has shown the distortion situation of the band portion 20 when being against sharpening slot 24 of pressing when cutter, supposes that here the tip of band portion 20 is not limit by the inner wall surface of inner casing 4.From Fig. 5 B, can obviously find out,, just can not form the final groove that has protruding side if the end of band portion 20 is unrestricted.
Fig. 6 has shown the cutter 40 that utilizes above-mentioned knife sharpener sharpening good.As shown in circle among the figure, final groove 44 is formed in the extension region of about 0.02-0.2 millimeter that the tip by the blade 42 of cutter 40 begins.In knife sharpener, according to preferred aspect, the grinding angle α that the default angle of the crossing of band portion 20, elastic characteristic and other characteristic all are selected to the blade 42 that makes cutter 40 drops on about 18 and spends in the scope between 22 degree, and the angle β of final groove 44 drops on about 28 and spends between 32 degree.
Under the situation of using cutter 40, because the two sides of the final groove 44 on the blade 42 all forms convex, therefore cutter is easy to separate with the object that will be cut, and compares with the cutter that the two sides of final groove 44 forms flat shape, and the cutting performance during cutting is good.
And because the open-angle of sharpening slot 24 surpasses the default angle of the crossing in sharpening, the angle β of therefore final groove 44 is also greater than the angle α of blade 42.As a result, the blade breach that causes owing to the disappearance of hard alloy particle or analog is difficult to take place, and the sharp knife edges of cutter can keep for a long time.Thereby do not need frequent sharpening cutter.
The present invention is not limited to first embodiment, and different distortion can be arranged.For example, shell 2 also can be made by resin moulded, so that have the shape of easy gripping.Also can be on inner casing 4 an integrally formed grip part, thereby need not set shell 2.
In first embodiment, the inner wall surface of inner casing 4 plays a part stop member, and stop part has determined the maximum open width of sharpening slot 24 and the default angle of the crossing between the band portion 20.Yet, as stop part, also can provide as pin, this pin can be from certain position of the expansion portion of outside contact zones portion 20.
And even the tip of band portion 20 also contacts with the inner wall surface of inner casing 4 under non-working condition, and angle of the crossing θ equals the default angle of the crossing under non-working condition.Yet, by between the inner wall surface of the tip of band portion 20 and inner casing 4, providing a surplus, thereby the default angle of the crossing is arranged under the non-working condition greater than the angle of the crossing.
In first embodiment, though sharpening parts 14 comprise four band portions 20 intersected with each other, if having at least the two or more band portion 20 can be intersected with each other, then the quantity of band portion 20 be exactly enough.Yet in order to make band portion 20 keep suitable elastic characteristic and prevent that simultaneously cutter from swinging during sharpening, preferably the quantity of band portion 20 is four or more a plurality of.
In addition, although sharpening parts 14 are made of metal, it also can be made by resin or string.In this case, band portion and lapped face can be by the mixtures of moulding resin fiber or string and abrasive grains, and use the method for producing paper, self welding or binding agent to obtain certain thickness and integrally formed.
And, also can form band portion like this, wherein by a plurality of for example 400 orders of backing or the integrally formed lapped face of 600 purpose woven wires under heaping with the state that is integrated, wherein abrasive grains is embedded in the surface of silk screen.The thickness of the band portion that obtains in this case, can obtain adjusting by insert peeling paper between woven wire.
