The specific embodiment
Existing simultaneously referring to Fig. 1 to Fig. 3, the bail 100 according to one embodiment of the invention is shown.Bail 100 is the lenticular wire section, and it is as the anchor in the brushing tool (particularly toothbrush), the U-shaped brushing cluster is fixed in bunch hole that in the head such as the jug apparatus of toothbrush, forms.Bail 100 has substantial rectangular cross section (longitudinal section and cross section) and is microscler along longitudinal axis A-A.Certainly, can utilize other shape to form this bail.
This bail 100 is by the periphery definition that comprises top edge 10, feather edge 11, first side edge 12 and second side edge 13.This bail 100 has length L, height H and thickness t.The length L of bail 100 will depend on bunch hole size that it will insert, but for bunch hole of 1.7mm, preferable range is 2.09 to 2.13 millimeters, and is most preferably about 2.11 millimeters.Bail 100 height H also depend on the size of its final use, but for bunch hole of 1.70mm, preferable range is 1.49 to 1.51 millimeters, and is most preferably about 1.50 millimeters.Equally, bail 100 thickness t also will depend on its final use, but preferable range is 0.24 to 0.26 millimeter, and be most preferably about 0.25 millimeter.But the present invention is not so restriction and can utilize other size in all embodiment.Definite size in any final products will be by the type and size of a bunch hole size, brushing cluster, and brushing tool type of using this bail etc. decides.And, though being illustrated as, bail 100 has overall uniform thickness t, height H and length L, it is that reduce and/or irregular gradually that one or more in these sizes can be.
In the illustrated embodiment, the edge 10-13 of bail 100 is essentially smooth.But in other embodiments, one or more being configured as among the edge 10-13 provides the additional cluster maintenance and/or reduces the pressure at the brushing cluster turn of bilge.For example, lateral edges 12-13 can be jagged, sharp-pointed or the band barb, and that feather edge 11 can be is round.
Bail 100 also comprises first first type surface 20 and second first type surface 21.Second first type surface 21 and first first type surface 20 make bail 100 be the flat rectangular platy structure relatively.First first type surface 20 comprises the first group of groove 30 that is formed in first first type surface 20 and covers whole basically first first type surface 20.Institute fluted 30 is arranged to parallel basically and spaced at equal intervals each other.But in certain embodiments, fluted 30 can be not parallel basically and the distance between adjacent grooves can change brokenly or as the function of one or two distance in lateral edges 12-13.
Because groove 30 results spaced apart, continual ridge 31 is formed between the adjacent grooves 30.Preferably, this ridge 31 is for microscler band and be not segmentation.In other words, preferably, first first type surface 20 does not comprise the groove that intersects each other.In brief, the groove pattern on first first type surface 20 does not preferably have any crossing groove.
For illustrated preferred embodiment, groove 30 has linearity configuration, and each groove 30 extends along recess axis B-B.But in other embodiments, groove 30 can be crooked, meander-shaped or irregularly shaped.
Groove 30 is preferably with 0.29 to 0.31 millimeter and most preferably about 0.30 mm distance D and be spaced apart from each other.Groove 30 preferably has 0.09 millimeter to 0.11 millimeter width W, and is most preferably about 0.10 millimeter.In one embodiment, preferably, the ratio between distance B and width W is in 3.0 to 4.0 scope and be most preferably 3.0.Groove 30 has 0.09 millimeter to 0.11 millimeter and be most preferably about 0.11 millimeter degree of depth.But the definite size of groove and its pattern can different to a great extent and not thought restriction the present invention, only if statement clearly in claim.But in one embodiment, the degree of depth of groove 30 preferably and be not more than 1/3rd of bail 100 thickness t.Find that also the degree of depth that groove 30 is had greater than thickness t 1/3rd causes the 100 improper distortions of line/bail.
The whole height H that groove 30 extends bail 100 extends to top edge 10 from feather edge 11.Groove 30 is directed so that tilt with respect to longitudinal axis A-A on first first type surface 20 of bail 100.Consider that with other a kind of mode the longitudinal axis A-A of the recess axis B-B of each in the groove 30 and bail 100 forms non-perpendicular angle.More specifically, the recess axis B-B of groove 30 intersects with acute angle, theta and longitudinal axis A-A, and acute angle, theta is chosen as the structural intergrity that sufficient bunch of maintenance is provided and keeps bail 100 in being inserted in toothbrush the time especially.Also amazing and be surprised to find that acute angle, theta realizing playing decisive role aspect the required enhancing bunch maintenance target, also depends on the metal of structure.The angle of also finding groove pattern allow to be used more cheap and/or softer metal and can not cause undesired line distortion and/or curl.But selected metal should be not soft to making the impression of groove pattern cause undesired distortion and curling.For example, find that aluminium is unaccommodated under most of situation.In a kind of desirable embodiment, the metal of selecting to be used for bail 100 makes its Brinell hardness less than the Brinell hardness of nickel-Yin but greater than the Brinell hardness of aluminium.
Through experiment, find in order to process the bail 100 of good behaviour from brass, need acute angle, theta be 40 degree to 70 degree, more preferably be that 55 degree are spent with 65 degree and most preferably about 60.For brass, when acute angle, theta was spent less than 40, line had the tendency of distortion and coiling.But, for brass, when angle is spent greater than 70, be difficult to impress angled groove pattern.And when the acute angle, theta of groove within the required range the time, the experiment of using the destructive testing of toothbrush to carry out shows that a bunch maintenance increases up to 25% amazingly when being with groove with other or not comparing with the anchor of groove.
Groove 30 is orientated from the first side edge 12 and begins to the second side that edge 13 is inclined upwardly to top edge 10 from feather edge 11 on first first type surface 20.Certainly, if need, groove 30 can be arranged in the opposite direction, that is, edge 13 begins to the first side that edge 12 is inclined upwardly to top edge 10 from feather edge 11 from the second side.Second first type surface 21 of bail 100 is preferably the smooth surface that has basically no groove or other pattern.(as will discussing about Fig. 7 to Fig. 9 hereinafter) in other embodiments, second first type surface 21 also can be patterned as the band groove.
Mould roll extrusion capable of using or punching press latten(-tin) form groove 30 and then this sheet are cut into required band, then this band cutting are formed bail 100
The existing while will be explained toothbrush 200 referring to Fig. 4 to Fig. 6, and wherein each in the brushing cluster 50 is anchored in bunch hole 215 by one of bail 100.Though show brushing cluster 50, also can use other cleaning element, comprise elastomeric fingers, fiber etc.Toothbrush 200 comprises head 210 and the neck 220 that extends to microscler handle.A plurality of bunches of holes 215 are formed in the front surface 211 of head 210.Head 210 is usually by constituting such as polyacrylic duroplasts.
In a plurality of bunches of holes 215 in toothbrush head 210 each from the head 210 front surface 211 along central axis C-C to extending below.Bunch hole 215 is preferably the circular inner hole that is formed in the head 210.Certainly, if need, bunch hole 215 can form other shape.
During manufacture, brushing cluster 50 bends to U-shaped and is fixed in bunch hole 215 by bail 100.With bail 100 be driven into make each brushing cluster 50 bend to U-shaped in bunch hole 215 and comprise turn of bilge 51 and two extend legs 52,53.The leg 52,53 of brushing cluster 50 extends upward and comes out from hole 215 and above the front surface 211 of head 210.The feather edge 11 of the turn of bilge of brushing cluster 50 or sweep 51 contact bails 100, and two legs 52,53 extend upward and limit the visible bristle of toothbrush.
Two lateral edges 12-13 that see each bail 10 extend in the opposing sidewalls in each hole 215 slightly.The gyrobearing that comprises the plane of each bail 100 is not vital, that is, bail 100 can rotate around the gyrobearing of its center vertical axis from about 45 degree through before installing, making it differently, installs to take any required orientation.But preferably, bail 100 is positioned to make in this bunch hole 215 that the longitudinal axis A-A of bail 100 is substantially perpendicular to the central axis C-C in bunch hole 215.
Existing simultaneously referring to Fig. 7 to Fig. 9, bail 100A according to a second embodiment of the present invention is shown.The basic structure of bail 100A is identical with the basic structure of bail 100.Therefore, use identical Reference numeral to add that suffix " A " discerns corresponding member and characteristic.For fear of redundancy, be applicatory through understanding aforementioned discussion, those characteristics of the bail 100A different with bail 100 will only be discussed hereinafter.
Main difference between bail 100A and bail 100 is that first group of groove 30A in being formed at the first first type surface 20A, the second first type surface 21A of bail 100A comprises second group of groove 40A.Preceding text also are applicable to groove 30A and groove 40A substantially about the discussion of the groove 30 of bail 100 and are combined in here by reference.But should be noted that in this embodiment of the present invention, bail 100A is not limited to the definite scope of acute angle, theta.But still preferably acute angle is that 40 degree are to 70 degree.
Should be pointed out that groove 30A in the first surface 20A that is formed at bail 100A is orientated from the first side edge 12 and begins to the second side that edge 13 is inclined upwardly to top edge 11A from feather edge 10A.But be formed at that groove 40A in the second surface 21A of bail 100A is oriented to that the second first type surface 21A goes up so that edge 13A begins to the first side that edge 12 is inclined upwardly to top edge 10A from feather edge 11A from the second side.In other words, groove 30A and groove 40A extend on the contrary inclination direction.Certainly, groove 30A and groove 40A well azimuth can be alternately.Preferably, groove 30A and groove 40A are arranged such that its length along the opening of top edge 10A and feather edge 11A along bail 100A alternately.
