Description

SPACER FITTING FOR AUTOMOTIVE WIPER ARM CONNECTION ADAPTERTECHNICAL FIELD

[0001] The present invention relates to interlocking mechanisms and systems between mechanical components. More particularly, the present invention relates to interface mechanisms associated with interlocking features between automotive wiper arm and blade assembly connections.BACKGROUND OF THE INVENTION

[0002] In the automotive field of vehicle wiper systems, manufacturers are seeking ways to improve and flexibly adapt connections between wiper arm types of various wiper blade assemblies such that adaption will properly qualify fit, form and function across most if not all vehicle models within a conceivable consumer market. Another consideration between wiper arm and wiper blade functional connectivity is to enable facilitated interconnectivity between installation and disassembly states and guarding against inadvertent detachment of wiper blade assemblies from the wiper arm to achieve a redundantly secured condition between interfacing components. Certain wiper driven systems require high reliability and longevity over a wiper design's lifecycle until the time for subsequent blade replacement such that a secured connection must endure reliably against separation between essential components even beyond a wiper blade's useful performance.

[0003] Among enhancement goals, automakers demand resilient wiper arm and blade connections that can be assembled, disassembled or replaced with facilitated ease by hand without additional tools. Automakers also seek a streamlined connection design with minimal component counts that can be assembled or disassembled within a brief time period singlehandedly through simplified movement without the pinching, hang-ups or injury often experienced by users that perform the installation or disassembly. To date, manufacturers have resorted to supplemental fasteners, tools, and the engagement of both hands or complex features to ensure such resilient connections. This approach has rendered less than satisfactory results by committing users to extra effort, cumbersome manipulation fumbling, or focused eyestrain and risks to damaging intricate features that can defeat a successfulinterlocking outcome and resilient performance results. While such concerted efforts can improve reliable blade performance, previous iterations of wiper manufactured designs have often lead to incompatible solutions over a wide array of wiper brand products, which has left a gap in the automotive field for offering an equivalent and effective solution across many competitor brands.

[0004] Such conventional practices to achieve this universally compatible and resilient connector system can facilitate assembly or disassembly without cumbersome tools while allowing a secure means to join together associated wiper components and ensure reliable performance without disruption or accidental blade detachment during service. Accordingly in the automotive field, there is a need for a universally compatible connector that adapts various wiper blade products to a multitude of wiper arm types that can reliably secure associated wiper blade connections beyond the expected service life of performance. Furthermore, needs are addressed that promote aesthetic design flexibility for producing cost-effective and resilient interface connections. Unique wiper arm-to-blade arrangements can be formulated through various wiper arm design types and commercial product standards to resolve and meet the industry's sought-after objectives.SUMMARY OF THE INVENTION

[0052] The description set forth below as connected with the incorporated drawings are intended as a description of various embodiments of the disclosed subject matter and are not necessarily intended to represent any one select embodiment. In certain instances, the description can include specific details for purposes of providing an understanding of the disclosed embodiments. However, it will be apparent to those skilled in the art that the disclosed embodiments can be practiced without those specific details. In some instances, well-known structures and components can be shown in block diagram form in order to avoid obscuring concepts or design variations of the disclosed subject matter.

[0053] In the automotive field of wiper systems, automakers seek to improve wiper features and operations or desire technical enhancements in order to achieve useful functions, options and reliable performance that mutually satisfies vehicle consumers while improving customer satisfaction ratings, which can enhance manufacturer brands in a cost-effective way.

[0054] An existing general concern with a universal wiper system is connector compatibility with a variety of wiper arm ends from different standard types and ensuring resilient fit within the connector such that the wiper arm end does not rattle, shift out of position or inadvertently detach over a course of extensive cleaning cycles beyond the anticipated performance and service life before blade replacement. These concerns with the desirable attributes for facilitating blade assembly replacement by a simplified means and without complicated tools has spurred an evolution of design development at the connector level of detail features to refine aspects with the subject invention. Because a variety of wiper arm types require particular fit and form for similar functions, one needs to conform with all or the most predominate commercially available wiper arm standards to ensure high uniformity tolerance fit through an intermediary component that resolves universal compatibility of wiper arm-to-blade problem in a simplified way while also ensuring the reliable attachment challenge.

[0055] Among enhancement goals, automakers and customers demand easy blade replacement. Additionally, customers seek a tool-free universally compatible wiper arm-to- blade connector across all if not most commercially available brands to simplify blade replacement. Although there can exist various competing solutions in the field that allow simplified interlocking assembly or disassembly at the connector interface, most systems have remained unreliable such that they break or become damaged to burden maintenance or service and fail to perform reliably over the course of anticipated lifecycle performance.

[0056] Another particular enhancement that automakers have demanded is a reliable means of interlocking features at the connector interface to promote resilient wiper blade operation without worry about accidental separation. Consequently, conventional limitations and practices present significant drawbacks for adaptive wiper connection systems over the expected design life of such components. The conventional approaches often lead customers and automotive drivers to dis-satisfaction from premature failures and performance deficiencies or to significant frustration when one needs to replace wipers time and time again before one enjoys the results of blade replacement between sooner than anticipated service periods - even with the more expensive brand wiper blade manufacturers. Accordingly in the automotive field, there's been a need for significant reliability andperformance enhancements and the desire to adopt a source with features that can extend the longevity, performance and simplified servicing of replacement versus a recent trend of costly but unreliable wiper blades from other sources in the market.

[0057] In FIG. 1A, an inventive embodiment is illustrated of an automotive wiper adapter system 1000 that provides a wiper arm-to-wiper blade connector 100 or product connection. The connector 100 illustrates components that may include a connector base 30 with pivot base 40 and spacer fitting 50 with beauty cover 70. The beauty cover 70 may adopt an inverted U-shaped cross-section and feature a number of finger reliefs 19 along the exterior surface that can be impressed at an end of the beauty cover 70 that may be used to promote or facilitate articulation. The beauty cover 70 may also feature surface ribbing 66 along the exterior in order to facilitate manual handling and facilitate gripping for manipulation towards servicing, disassembly or securing connections, by examples.

[0058] Among the figures, connector 100 is depicted where opposing nubs 6 on the locking cap 10 can be designed to support rotational pivoting and articulation of the locking cap 10 away from or towards the wiper arm assembly A from an openly free condition into an installed condition to restrain or secure the wiper arm assembly A in-place as the opposing nubs 6 pivotably support articulation of the locking cap 10 into an affixing lock or retracted condition [seen in FIGs. 3A, 3C, 5B, 6],

[0059] FIG. IB illustrates the connector 100 of adaptive connector assembly C joined with wiper blade assembly B in an embodiment of the invention. The beauty cover 70 may feature a number of ribbed impressions 66 that may be adapted for manual manipulation at intermediary sections along outer surfaces of the beauty cover 70. The beauty cover 70 may include an area section along an exterior reserved for markings or labels through a number of emboss 33 features formed during part molding or emplaced subsequent to part formation.

[0060] FIG. 1C illustrates the connector 100 of adaptive connector assembly C joined with wiper arm assembly A in an embodiment of the invention. Constituents of the connector 100 may include a connector base 30 that is configured to snap-click into a pivot base 40. Thepivot base 40 may have thru-holes 8 along the pivot base 40. The adaptive connector 100 may also include a rotatable platform 20, a spacer fitting 50 and a locking cap 10 configured to articulate over the wiper arm assembly A and beauty cover 70, where all together the rotatable platform 20, the spacer fitting 50 and a locking cap 10 may be adapted to interface and snap-lock over the pivot base 40.

[0061] FIG. ID illustrates an isometric perspective of an embodiment of a wiper adapter system with removed component portions to facilitate visualization of the interface of spacer fitting interlocked with the rotatable platform joined with the connector base according to an embodiment of the invention. FIG. ID illustrates that spacer fitting 50 can be interlocked over rotatable platform 20 and may be configured to snap-click onto connector base 30 and may be further configured to snap-click into a pivot base 40. The connector base 30 may be configured to snap-click to pivot base 40 at an interface of the thru-holes 8 and opposing studs 13 of the connector base 30 in an embodiment of the invention.

[0062] FIG. 2 illustrates adaptive compatibility of a connection mechanism or connector 100 with various depicted wiper arm type-standards according to an embodiment of the present invention. The connector 100 can demonstrate compatibility with at least the illustrated wiper arm type standards that may be received by the connector 100.

[0063] FIGs. 3A, 3B, 3C and 3D depict the constituents of connector 100 that may include a connector base 30 with opposing studs 13 along each lateral wall 11 of the connector base 30. The opposing studs 13 may be configured to snap-lock into a number of thru-holes 8 existing in the pivot base 40 or such features may be alternatively interposed between the connector base 30 and pivot base 40 components. The connector 100 may include a locking cap 10, a rotatable platform 20, a connector base 30, a pivot base 40, a spacer fitting 50 and a beauty cover 70. A pivot base 40 can include thru-holes 8 along each lateral wall 42 of the pivot base 40, where the opposing studs 13 of the connector base 30 can be configured to snap-lock into the thru-holes 8 of pivot base 40 upon mating with one another to form an adaptive connector assembly C.

[0064] The lateral walls 11 of the connector base 30 can form a thickness range of between 0.8 mm to 3.0 mm along a longitudinal dimension of each connector base's lateral wall 11 so as to maintain sufficient rigidity and strength to sufficiently interface with adjoining components under click-lock force or a compression fit without degradation or damage to the connector base 30 component. A beauty cover 70 may be pre-installed with the locking cap 10 joined with the connector base 30, pivot base 40, spacer fitting 50 such that portions of the connector 100 and wiper arm assembly A may supplement reinforcement through a type of slide lock with the receiving of wiper arm assembly A into the connector 100.

[0065] An embodiment of a connector 100 is illustrated wherein the opposing studs 13 take the form of a round protrusion 13; however, the inventors contemplate that the opposing studs 13 may take alternate forms such as a conical, spherical, semi-spherical, oblong or bulbous form features in-kind so as to enable pivoting between the connector base 30 and the pivot base 40. The spacer fitting 50 formed from a polymeric composition may interlock over a rotatable platform 20. The spacer fitting 50 with the rotatable platform 20 attachable to the connector base 30. Furthermore FIG. 3A shows a combination of rotatable platform 20 snap-locked into position with the connector base 30 through a joining and articulation at a distal pivot 99 feature.

[0066] The lateral walls 42 of the pivot base 40 may form a thickness range of between 0.8 mm to 3.0 mm along a longitudinal dimension of each pivot base's lateral wall 42 so as to maintain sufficient rigidity and strength to sufficiently interface with adjoining components under click-lock force or compression fit without degradation or damage to the pivot base 40 component. Pictorials where the locking cap 10 can snap-lock into engagement over the connector base 30 and the rotatable platform 20 about pivot nub 6 may be depicted in FIGs. 1C, 3A, 3C, 5A and 6. Furthermore, the locking cap 10 may be configured to articulate over, cover and secure over onto the beauty cover 70 through the following described snap-lock engagement.

[0067] A snap-lock or click-lock is an engagement feature or a fastening method where two or more components may be joined together by a snapping or clicking mechanism, creating a secure connection. Such features using the described engagement design may use spring-loaded or molded tabs, flexible members and ridges to lock parts together without requiring additional tools or fasteners like screws, rivets or adhesives. An audible "snap" or "click" implemented by this described engagement feature signals that the associated interface components are properly aligned and securely engaged. Release features of such a secured engagement may also use molded tabs or flexible nubs or impressions along associated components to disassemble, dislodge or enable separation of such joined components without requiring additional or cumbersome tools, as well.

[0068] FIGs. 1A, 3A, 3B, 3C, 3D, 5A and 6 further depict perspectives where the connector base 30 may be configured to click-lock into the pivot base 40 at an interface of thru-holes 8 and the opposing studs 13. The wiper arm-to-wiper blade connection or adaptive connector 100 may be further reinforced into an installed position when the locking cap 10 interlocks secure over the beauty cover 70. The adaptive connector 100 may have a spacer fitting 50 that is adapted to interface between the rotatable platform 20 and the beauty cover 70. The spacer fitting 50 may be formed from a framework part 5 that is configured to interlock over a rotatable platform 20 joined with a connector base 30.

[0069] Among the figures, connector 100 is depicted where opposing nubs 6 on the locking cap 10 can be designed to support rotational pivoting and articulate the locking cap 10 away from or towards the wiper arm assembly A from an openly free condition into an installed condition to restrain or secure the wiper arm assembly A into place as the opposing nubs 6 pivotably support articulation of the locking cap 10 into an affixing lock or retracted condition [as seen in FIGs. 3A, 3C, 5B, 6],

[0070] FIGs. 3A, 3B, 3C, 5A, 5B and 6 depict features for an adaptive connector 100 of a connection mechanism of a wiper system that may include a connector base 30 having opposing studs 13 along each lateral wall 11 of the connector base 30 that is configured to snap-click into a number of thru-holes 8 of a pivot base 40. The pivot base 40 may have thru- holes 8 along each lateral wall 42 of the pivot base 40. The adaptive connector 100 may also include a rotatable platform 20, a framework part 5 of a spacer fitting 50 and a locking cap 10 configured to snap-click onto the connector base 30, where all together the rotatableplatform 20, the spacer fitting 50 and a locking cap 10 may be configured to snap-click into the pivot base 40.

[0071] FIG. 4 illustrates an isometric perspective and exemplary embodiment of the spacer fitting 50 that may be formed from a framework part 5 and may have flexible legs 22 on opposing lateral sides 16 of the spacer fitting 50 (or framework part 5), which may be adapted to land and interlock with a proximal end [near 9] of a wiper arm assembly A and at a rear- distal end 15 of the spacer fitting 50, where the wiper arm assembly A may be designed to settle between flexible legs 22 at each retention pad 7 and at each stopper catch 9 of the spacer fitting 50. The framework part 5 may include a number of stopper catches 9 at a proximal end 12 of the spacer fitting 50 and a number of landing pads 7 at a distal end 15 of the spacer fitting 50. The stopper catches 9 may reside along opposing sides of each lateral wall 16 of the framework part 5. The landing pads 7 may also reside along opposing sides of each lateral wall 16 of the framework part 5. The framework part 5 may be configured to straddle from under the wiper arm assembly A [as seen in FIGs. 5B, 5C, 5D] and together may be configured to join onto rotatable platform 20 and a connector base 30 together as illustrated in FIGs. 3A and 6.

[0072] The landing pad 7 feature (such as a boss, stud, or protrusion by non-limiting example) may be designed to connect with a wiper arm's end interface feature and may serve to align, guide or secure the wiper arm's position relative to a datum feature based from the landing pad 7 so as to anchor and pivot from a distal end 15 of the spacer fitting 50 such that a landing proximal end 12 of the wiper arm is properly oriented to the stopper catch 9 location as FIGs. 5B, 5C, 5D and 6 illustrate. The landing pads 7 may be formed to facilitate a detent or pivotable restraint feature for a wiper arm to articulate into position to-from a stopper catch 9 location such that any conceivable number of forms may be contemplated to articulate from a landing pad 7. The landing pad 7 may inclusively adopt but not be limited by features of a curvature surface, lobed contact surface, rounded pin or other conceivable form with bearing-surface and kinematically guiding capability features.

[0073] The stopper catch 9 feature may be designed to mate with an end of a wiper arm's interface feature (such as a corner or protrusion by non-limiting example) and mayparticularly direct the wiper arm's edge to stopper catch 9 so as to bottom-out and be securely restrained at a proximal end 12 of the spacer fitting 50 [as seen in FIGs. 3B, 4, 5D] . In this depicted way, the stopper catch 9 may secure the wiper arm end and halt the wiper arm assembly A from dislodging and abutting against locking cap 10 while also placing the wiper arm's articulable motion in-constraint when joined in combination with an installed beauty cover 70 for additional reinforcement. The stopper catch 9 may be configured to bottom-out against a detent feature 77 of the spacer fitting 50 while on the connector base 30 in-assembly and under an installed condition.

[0074] The stopper catch 9 feature may be formed to facilitate a stopper or constraint function against a wiper arm end such that any conceivable number of shapes may be contemplated to perform the stated function. The stopper catch 9 may include but not be limited to forms of an L-shape or right angle, detent block, fork-end, spherical, scoop or other male-female interfacing feature. A fork-end feature to mean a root protrusion with one or multiple extensions or fingers protruding from the root protrusion.

[0075] As depicted in FIGs. 3B, 5E and 6, the spacer fitting 50 may further include an upper side 17 feature of the framework part 5 where a number of cusps 44 or crown risers may be configured to interlock with an interface side 88 of a wiper arm assembly A. The cusps 44 are adapted to interlock with the wiper arm assembly A during a mating interface at a coupling section with the wiper arm assembly A. A beauty cover 70 (depicted in FIGs. 1A, IB, 1C, 3D, 5A and 6) may overlap the wiper arm assembly A and spacer fitting 50 combination to mutually install over both components to slidably install towards locking cap 10 by a lockable interface feature to secure the spacer fitting 50 into position and supplement reinforcement of the wiper arm assembly A into a secured installation position (see FIG. 6).

[0076] The beauty cover 70 may be configured to encompass the framework part 5 upon installation of the joined spacer fitting 50 and wiper arm assembly A. The framework part 5 of the spacer fitting 50 may be formed from any suitable material but is preferred to be formed from a polymeric material such as polyoxymethylene (POM), Acrylonitrile Butadiene Styrene (ABS), polyamide (PA), polypropylene (PP) by non-limiting examples. Any additional suitable material may be applied that can provide a certain elasticity that enables theassociated components to mount-unmount the spacer fitting 50 or from the other interfacing components. The spacer fitting 50 wall thickness or framework structure may be formed from the described polymeric material in a suitable thickness range of between 0.7 mm to 3.0 mm or a preferable thickness range between 0.7 mm to 2.0 mm to avoid inoperable damage or breakage.

[0077] FIGs. 5A through 5E illustrate various perspective views between components of the adaptive connector assembly C receiving a wiper arm assembly A where some interfacing components are omitted to facilitate visual interpretations and a better understanding between specific components. Illustrations from FIG. 5A through 5E depict a wiper arm A that can interface with a connector 100 of the adaptive connector assembly C or a connection mechanism of the wiper assembly system 1000. The adaptive connector 100 may include constituents of a connector base 30 having opposing studs 13 along each lateral wall 11 of the connector base 30. The opposing studs 13 may be configured to snap-lock into a number of thru-holes 8 of a pivot base 40.

[0078] The pivot base 40 may have thru-holes 8 along each lateral wall 42 of the pivot base 40. The connector 100 may further include a rotatable platform 20, a framework part 5 of a spacer fitting 50 and a locking cap 10 configured to click-lock onto the connector base 30, where all together the rotatable platform 20, a framework part 5 of a spacer fitting 50 and a locking cap 10 may be configured to click-lock into joining with the pivot base 40.
