Description

Wiper blade package

Technical field

The present invention relates to packing, relate more specifically to Wiper blade package (wiper blade packaging), it is particularly suitable for keeping the automobile-used swept area of wiper blade of bar type (wiper blade), particularly is suitable for the structure of the bar of those prebucklings.

The sequence number that the application requires on May 3rd, 2004 to submit is 60/567, the sequence number that 748 U.S. Provisional Application and on July 13rd, 2004 submit is 60/587,392 U.S. Provisional Application benefit and preceence, the whole of these two applications are combined into list of references clearly at this.

Background technology

In the whole U.S. and the world, the bar type swept area of wiper blade of air baffle or Windshield is developing very generally.Bar type swept area of wiper blade has the elongated bar " backbone " along its curved in length.They also have attached to the rubber wiper element of a side of bar with attached on the bar and from the outward extending connecting device that is used for releasedly swept area of wiper blade being installed on the vehicle of its opposite side.The example of bar type swept area of wiper blade is in U.S. Patent No. 6,836, and is open in 925, No.6,813,923, and No.6,550,096.

Crooked bar helps to guarantee to apply more constant and uniform pressure along whole Windshield, and more level and smooth more consistent scraping is provided.And conventional engage frame swept area of wiper blade typically has about six or eight spot pressures in somewhere, described bar type swept area of wiper blade has unlimited a plurality of spot pressure basically, helps to guarantee that wiper element is pushed against on the Windshield with continuous substantially pressure along the roughly whole length of blade.Article one, the bar of bending also can be preferably crooked consistent with all car bumper wind glass, it further guarantees more level and smooth more consistent scraping action.

Fig. 1 explanation is used for the preferred embodiment of the packing 40 of crooked bar type swept area of wiper blade 42, and this packing is configured and is configured to admit and keep releasedly described blade 42.Packing 40 is configured to keep bar type swept area of wiper blade 42 also to protect it simultaneously with local at least straightened condition.Packing 40 preferably is configured and is arranged to Reclosable ground and also keeps bar type swept area of wiper blade 42 under straightened condition and not contact with its any part of rubber-like wiper element 56 releasedly.

The exemplary bar type swept area of wiper blade of describing among Fig. 1 42 has a bar 44, also is called backbone, and its bending makes it have at least one radius of curvature.Bar 44 is rectangular cross section basically and has

outer surface

46,48 and a pair of lateral edge 50 and 52.Bar 44 forms or is pre-formed to bending, and for example in mode shown in Figure 1, bar 44 typically is formed from steel, for example spring steel etc.

Coupling device 54 is attached on the bar 44 and is used for releasedly with reciprocating the scrape water arm (not shown) of swept area of wiper blade 42 attached to vehicle.Coupling device 54 can comprise connecting device and can be constituted as admits dissimilar connecting devices, is used for blade 42 attached to dissimilar vehicles and scrape the water arm assembly.

Blade 42 has the wiper element of being made by the elastomeric material of for example rubber 56, and comprises scraping point or edge 58, and it contacts with the Windshield of car or air baffle in Windshield Wiper operating period water is struck off.Scraping edge 58 is active sections 60 that wiper element 56 is essentially triangle, wiper element is by the bar 64 (sometimes be called spine on) of narrow relatively hinge 62 (Fig. 4) attached to broad, and it is for example waited by welding and on the outside face 48 attached to bar.

Referring to Fig. 2-4, packing 40 has a pair of package half or

panel

66 and 68 in addition, and one of them panel 66 is that three-dimensional modeling is to hold to small part bar type swept area of wiper blade 42 at least.After tip arrangement 42 on the panel 66 of moulding, for example in the mode of Fig. 2 description, another package panel 68 overlaps on described blade 42 and engages with closed package 40 with package panel 66.Shown in Fig. 3 and 4, when closure, packing 40 preferably covers and protects wiper element 56 along its whole length basically, prevents when packing its distortion, warpage or other permanent deformation.As a result, during shipping, storage, the retail display and up to taking out blade 42 as the terminal user and it being placed on their car, the packing 40 that constitutes according to the present invention can both be protected wiper element 56.

If wish blade 42 is put back in the packing 40, the joint between

panel

66 and 68 is preferably releasable, to allow packing 40 to open taking-up blade 42 and can be again closed.Be illustrated in packing 40 under the situation of retail sales counter, it is a Reclosable, advantageously makes client's the return of goods can be put back to same packing 40 (or a different packing 40) and be put back into then in the showcase and can not demonstrate described blade 42 and is return.

Packing 40 preferably includes the spine 70 between panel 66 and 68.When packing 40 closures, spine 70 extends and overlapping at least a portion wiper element 56 along the length of packing 40 basically.As shown in Figure 4, when packing 40 closures, the scraping edge 58 of spine 70 overlapping wiper element 56, but be unlikely to contact with it at interval with described scraping edge 58.

By

corresponding hinge

72 and 74, spine 70 is attached on each

package panel

66 and 68, and described hinge is preferably existing hinge or analogue.Shown in Fig. 1-4, spine 70 passes through a hinge 72 attached to also passing through another hinge 74 on the panel 66 attached on the panel 68.Each

hinge

72 and 74 extends along spine 70 cooresponding longitudinal extension sides and preferably extends on its whole length basically.

As in Fig. 4, more clearly showing, each

hinge

72 and 74 preferred embodiment are that cross-sectional plane is C shape and has flat hinge section 76 and be arranged between a pair of separated and crooked hinge section 78 and 80, each hinge section wherein be connected respectively on the spine 70 and

package panel

66 and 68 in one of on.Because at the packing period of contact, for example during automatic Wiper blade package, and when packing 40 closures, for keeping all parts to be properly spaced and locating and in packing 40, admit swept area of wiper blade 42 toward each other, this preferred hinge arrangement helps

package panel

66 and 68 and the aligning mutually and locating of spine 70, so it is favourable.When bar type swept area of wiper blade 42 in packing 40 and packing 40 when being closed, a kind of like this hinge arrangement of C shape preferably also helps to make packing 40 more solid and can resist better because the moment of deflection of wanting to turn back to its curved shape of its hope.

Two

package panels

66 and 68 can be three-dimensional modelings, for example in the mode shown in Fig. 1-2.At least package panel 66 and one of 68 with preferred two comprise that all one keeps the seat 82 of bar 44 of the swept area of wiper blade 42 of a part at least.Seat 82 preferably constitutes and keeps bar 44 to be at least a portion straightened condition, and the trend of its original curved shape is got back in the bending of wanting that reacts on it.

In the preferred packing embodiment shown in Fig. 1-4, straight blade bar keeps seat 82 to be configured to keep the bar 44 of bar type swept area of wiper blade 42 to be in straightened condition basically, thus the transverse width minimum when making bar type swept area of wiper blade 42 packaged.When along many to interval location at least, i.e. at least three interval locations enter seat when interior along two outside faces 46 of

bar

44 and 48 along bar 44 most of length steady arms 44, and preferably 82 to constitute maintenance bar 44 straight basically.

When such Support Position may overlap mutually or become delegation mutually, the Support Position that is positioned at a side of the bar 44 of taking one's seat preferably was staggered with respect to the Support Position of the another side that is located at bar 44, the packing preferred embodiment shown in Fig. 1-4.For example, in the preferred embodiment, keep straight and keep support in the bar 44 present 82 preferably to be set at or

surface

46 and 48 parts and adjoin each end of swept area of wiper blade 42, such support is extended preferably to adjoin the corresponding side of swept area of wiper blade coupling device 54 along the both sides of bar 44.Staggered like this support advantageously is provided with the one formation with

package panel

66 and 68 releasable joints, thereby makes the size minimum of packing 40.

One and preferred two

package panels

66 and 68 comprise a blade cradle 102, and itself and seat 82 combineds action are to help alleviating during the packing of packing and preferably stably keep at least a portion bar blade 42 equally when packing 40 is closed.For example, Fig. 2 illustrates that bar type swept area of wiper blade 42 is received within the blade cradle 102, and this carriage has the three-dimensional modeling structure that forms in package panel 66, and its bar 44 is placed on its seat 82, and packing 40 is ready to around swept area of wiper blade 42 closures.In the preferred embodiment shown in Fig. 1-4, blade cradle 102 comprises platform 104, and when the bar 44 of blade 42 is received within when adjoining in the seat 82, a wiper element bar of at least a portion or a side of spine 64 are sat thereon.During packaging, concerning operating personal or machine, by at first bar 44 is inserted seat 82 up to a side of wiper element bar or spine 64 platform 104 near carriage 102, guarantee that more easily bar 44 evenly inserts seat 82.

When packing 40 was closed around swept area of wiper blade 42, by as contact the retainer or the steady arm that maybe can contact with wiper element bar or spine 64, the platform 104 of carriage 102 also helped support blade 42 and keeps blade 42 to be in the interior desired locations of packing 40.Under the situations that two

package panels

66 and 68 so are provided with, the platform 104 of each panel 66 and each carriage 102 of 68 preferably also may clamp or near the bilateral of wiper element bar or spine 64, help to support it in packing 40.This clamping or positioning function advantageously also help suitably to arrange swept area of wiper blade 42 within packing 40, so that guarantee that packing 40 is not with scraping edge 58 and preferably do not contact with the active section 60 of wiper element 56.

By keeping bar type swept area of wiper blade 42 under straightened condition, advantageously reduced packing measurement.By packing 40 being configured to make it provide bar straight support for the bar 44 that is received in the blade in the packing 40, further reduce described packing measurement in integrated like this mode.This makes packing 40 be very suitable for the application of retail display, for example is placed on a box (not shown) in several packings 40, and this box also can be that double-ply is as retail display.Like this packing 40 also be very suitable on a shelf or by overhanging nail-plate in the shop or the retail display on the analogue.

Maximum lateral width minimum when keeping that bar type blade 42 is straight basically to make it packaged, the packing 40 that constitutes according to the present invention can arow be overhang on the retail display nail-plate and make adjacent each row to be not more than or the distance of the roughly same packing that is used for conventional swept area of wiper blade separates.In addition, by using packing 40 according to the present invention to reduce the package-width of bar type blade, advantageously take less capacity such as fruit bar 44 during not by straight (or even straight basically to compare flatness low slightly with preferred embodiment), it advantageously reduces transportation and holding cost.

The result, the packing 40 that constitutes according to the present invention keeps the bar type swept area of wiper blade 42 of prebuckling to be in straightened condition basically with reclosable ground releasedly, it has length and at the width of its wideest part, described length be its manyfold of the width of wide part and the most wide described degree are the manyfold of its thickness or the degree of depth.For example, so the packing 40 that constitutes can keep the length range of pre-bending curved bar type swept area of wiper blade 42 between ten inches and 30 inches, this packing has and is not more than three inches package-width, and is preferably two inches or less, and has package depth or the thickness that is not more than one inch.Packing 40 may have compact size like this, and with make irrelevant by synthetic, the polymerization or the plastic material of relative thin.For example, have can be between eight mils and 20 mils but the wall thickness that preferably changes between ten mils and 15 mils for the packing 40 of the preferred embodiment that is formed by polyethylene terephthalate (PET or PETE).If desired, can use another suitable material, for example polyvinylchloride (PVC).The size that packaged bar type swept area of wiper blade 42 can remain under the basic straightened condition the close package of finishing these hope is advantageously, even also like this when not having thin like this material to make packing 40.

Under the situation of utilizing PET or PVC to make, packing 40 preferably monolithic is thermoformed, and for example, preferably uses high speed shaft to the pressure forming processing etc.Packing 40 is preferably transparent, but if desired, can be manufactured into opaque so that colouring.If desired, packing 40 can comprise be molded or be formed on wherein sign (not shown) in addition.If desired, also can on packing 40, print off this sign.Also can form packing 40 and hold the card (not shown), for example overlay on the demonstration card on the spine 70, for example between

hinge

72 and 74, and/or overlay on one or two

package panel

66 and 68.

Under the situation of needs, packing 40 preferably three folding configurations also can constitute clam.When packing 40 can be constituted as an independent packaging, the preferred embodiment of the packing of describing in Fig. 1-4 40 was constituted as package nest.

Each locking devicen 84 comprises at least one breech lock, and it comprises a part of a package panel 66, a partial engagement of this part and another package panel 68.For example, in the preferred embodiment that Fig. 1-4 shows, each latch assembly 84 comprises a plurality of breech locks, each breech lock comprises and the integrally formed outwardly directed snap-fastener 86 of one of them package panel (for example being preferably panel 68), can be received within complementary snap-fastener 86 female parts 88 that are integrally formed in another package panel (for example being preferably panel 66).When all snap-fasteners 86 are configured on the panel, be panel 68 in this case, and all snap receivers 88 are configured on another panel, be panel 66 in this case, the position that should be realized that them can or be changed with the such opposite of demonstration among Fig. 1-4, makes a single package panel can have position one or more snap-fasteners and snap receivers thereon.

Each snap-fastener 86 preferably includes boss 90, this boss 90 is protruding from the pillar 92 of protuberance, this boss has the convex shoulder 94 that surrounds it, when the boss 90 of snap-fastener 86 is received in the pit 98 of snap receivers 88, this convex shoulder 94 is near convex shoulder 96, the pit 98 of this convex shoulder 96 in the base 100 of the protuberance that is formed on snap receivers 88.Provide suitable installation between snap-fastener 86 and snap receivers 88, for example flush fit, interference fit etc. have prevented undesirable disengaging.For example, the external diameter of boss 90 preferably equals or less times greater than the internal diameter of pit 98, described pit 98 admits boss 90 so that tight frictional engagement to be provided betwixt.

Each bar admits seat 82 preferably to be limited by a part of locking devicen 84 on a side, its outside and another side that is configured in swept area of wiper blade bar 44 in place is limited by guiding wall 106 at least a portion of swelling, described guiding wall is formed by the part that the coupling device in packing 40 holds each adjacent bracket platform 104 on 108 opposites, gap, and it is configured in bar in place 44 inboards.In the preferred embodiment that Fig. 1-4 describes, under the situation in bar 44 is received within the seat 82 of package panel 66, the part that forms the locking devicen 84 of 82 exterior section is the base 100 of each snap receivers 88.Be contained in the seat 82 of package panel 68 under the situation at bar 44, the part that forms the exterior locking devicen 84 of seat 82 is the pillar 92 of each snap-fastener 86.In order to help to provide elongated and straight basically seat 82 helping guaranteeing that bar 44 in place is sitting on the seat 82 basically straightly, each guiding wall 106 be basically the plane and be basically parallel to form on present 82 each respective strut 92 and the base 110 towards interior flat pillar 100.

Return the magnitude of moment of deflection of its normal curved shape according to wanting of when being received within packing 40, giving of swept area of wiper blade 42, packing 40 preferably constitutes the parts of strengthening on the one or more reinforcements that form and/or the structure on it, it helps packing to resist moment and does not have deflection or the deflection in the acceptable limit or tolerance limit at least.

For example, in the preferred embodiment that Fig. 1-4 shows, when packing 40 is sky, packing 40 preferably has the reinforcement flange of placing along a common plane 112, preferably make simultaneously flange 112 from the remainder of packing 40 basically or fully wrapped 40 the entire circumference adorned stretch out 1/8 inch.When the needs additional strength and the rigidity of structure, a part is strengthened flange 112 and is preferably included the part 114 that is broadened, so that along the straight-line extension of the central longitudinal axis that is parallel to packing 40, make its outward flange 116 be straight basically and be disposed in the outside of the locking devicen 84 of two

package panels

66 and 68 on one of at least or outwards arrange.For example, with reference to figure 1, wideer like this reinforcement flange 114 extends to the other end of packing 40 and below the coupling device of packing 40 is admitted depression 108 from an end of packing 40.This reinforcement flange 112, comprise when disposing wideer reinforcement flange or flange portion 114, be basically perpendicular to the one or more moment of deflections that in packing 40, cause and extend, and therefore described one or more moment of deflections of primary boycott, described moment is because the tendency that swept area of wiper blade 42 is wanted to turn back to or flexibly return its common curved shape produces by power being passed to packing 40.

If desired, wideer flange or flange portion 114 can be configured so that promote to have the packing of the other material that comprises swept area of wiper blade pad, connecting device or the like.If desired, can be provided at otch on flange or the flange portion 114 for such other materials.

In order to give packing 40 added strength, the platform 104 of each lever bracket frame 102 preferably has the strengthening rib 118 of the longitudinal extension that forms thereon.Each such strengthening rib 118 is elongated and length that have is lacked than the length of the carriage 102 that it was formed at.If desired, the carriage 102 on one or two in

package panel

66 and 68 can be basically extends rather than terminates in coupling device with the length of packing 40 and admits on side of depression 108 or the another side and make the strengthening rib of acquisition have the longer length that shows than at Fig. 1-4.For example, if desired, have the length of prolongation and equip under the situation of integrally formed strengthening rib at this carriage, rib can extend with the length of carriage basically.

In order when being easy to shaping Production and Packaging 40, increasing and help the intensity of maximization packing by thermoforming, when each rib 118 recessed each equipment with the platform 104 of the carriage 102 of such rib 118 in the time, each rib 118 is crooked or has the arcuate cross-section profile, makes that it is recessed structure.Each end of each such strengthening rib 118 is preferably justified, thereby advantageously provides improved packaging intensity, minimizes simultaneously along the formation of the stress protuberance of rib 118.When packing 40 closures, the rib 118 of a package panel 66 overlaps on another package panel 68, forms oblong torsion resistant tube or tubular construction (not shown), helps to increase hardness and torsional stiffness.

Each

package panel

66 and 68 preferably also comprises the elongated strengthening rib 120 that extends along corresponding adjacent hinge.Each rib 120 preferably extends and has crooked or the arcuate cross-section profile along packing 40 length basically.

The spine 70 of packing 40 also is that three-dimensional modeling is to increase packaging intensity and to improve the rigidity of structure.More clearly show as Fig. 4, spine 70 has a pair of end wall that separates 122, only show one of them at Fig. 4, between them, extend a pair of recessed strengthening rib 124, this strengthening rib 124 has crooked or arcuate cross-section, be formed on one and be preferably bending on two

package panels

66 and 68 or arc strengthening rib 120 identical or complementary.

In addition, described spine 70 has second pair of strengthening rib 126, they all protruding and each other configuration be acute angle so that at spine 70 be received between the scraper element of the swept area of wiper blade 42 in the packing 40 and form the roughly scraper element marginal gap depression 128 of vee shape.Each outwardly directed strengthening rib 126 preferably has the roughly cross-sectional profile of vee shape.These ribs 126 preferably extend along the length of packing 40 basically with the clearance recess 128 between spine 70 and scraper element edge 58.As the result that spine 70 extends along packing 40 length basically, its whole scraper element edge 58 that overlaps basically advantageously provides protection for whole wiper element 56 basically.

With reference to figure 4, when packing 40 closures, the part of the supporting platform 104 of each carriage 102 is near the point of the corresponding outwardly directed strengthening rib 126 of spine 70 or the part of end 130, produce the enhanced tube structure 132 of substantially elliptical, it extends with corresponding carriage length basically at least, and preferably extends with the length of packing 40 basically.The part that extends to the respective hinge of adjoining of spine also can be near the part of adjacent package panel, this panel also extend to identical hinge near, the mode that shows with Fig. 4 for example.When packing 40 is closed the mutual support on these surfaces or near ability also advantageously improve the ability that packing 40 is born the effect of broken and bend loading, make packing 40 more solid.

Because each snap-fastener 86 easily is pressed and engages with its corresponding snap receivers 88 when packing 40 closures, the packing 40 that constitutes according to the present invention is closed easily.When two
