Doghouse-shaped head

Abstract

A doghouse-shaped fastener assembly is provided for joining two components together at an adjustable pitch. The doghouse-shaped fastener assembly includes a first fastener and a second fastener. The assembly includes a doghouse-shaped feature on the first component, the doghouse-shaped feature being formed by a side wall and a bottom wall to form a cavity. The fastener has a retaining portion attached to the second component and a doghouse-shaped head fitting into the doghouse-shaped cavity. The doghouse-shaped head comprises two plates which are connected by a neck so that a gap is formed between the two plates. The spacing between the two components can be adjusted depending on the manner in which the fastener is inserted into the cavity, either in the first orientation or in the second orientation, allowing two different mounting heights to be achieved using the same fastener.

[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 671,365, filed July 15, 2024, and U.S. Provisional Patent Application No. 63 / 739,719, filed December 30, 2024, entitled “Head for Doghouse”, which is incorporated herein by reference. Background Technology

[0003] Automotive components require fastening technologies that are not only simple to manufacture and assemble but also highly reliable and efficient. The connection methods for components must typically be not only structurally sound but also cost-effective and suitable for mass production. Fasteners are commonly used to attach sub-panels, trim pieces, or brackets to the main structural panels.

[0004] These components must adapt to variations in design, tolerances, and installation requirements while maintaining a robust and consistent connection. In many cases, different applications require different spacing between components to accommodate design or functional constraints. Traditionally, this has necessitated the use of multiple fastener types or additional hardware, which increases the number of parts, complicates assembly, and raises manufacturing costs.

[0005] Therefore, there is a need for a fastener that can provide different component spacing configurations based solely on its mounting orientation, thereby simplifying inventory management and streamlining the assembly process. Summary of the Invention

[0029] Fasteners can be used to form a connection between a first component and a second component, such as an automotive panel. The disclosed fasteners provide a fastener having a kennel-shaped head that can provide different component spacing configurations based on its installation orientation.

[0030] In one example, a kennel-shaped fastener for forming a connection between a first component having a kennel-shaped feature and a second component includes a retention portion configured to engage the second component and a kennel-shaped head integrally formed with the retention portion and configured to slide along an axis into the kennel-shaped feature to selectively assume one of a first installation orientation to provide a first spacing between the first component and the second component and a second installation orientation to provide a second spacing between the first component and the second component, wherein the kennel-shaped head includes a first plate connected to a second plate by a neck to define a gap between the first plate and the second plate.

[0031] In another example, a kennel-shaped fastener assembly for forming a connection between a first component and a second component includes a kennel-shaped feature associated with the first component, wherein the kennel-shaped feature includes a set of sidewalls bridged by a bottom wall to define a recessed cavity, and a kennel-shaped fastener having a retention portion configured to engage the second component and a kennel-shaped head integrally formed with the retention portion and configured to engage the kennel-shaped feature, wherein the kennel-shaped head includes a first plate connected to a second plate by a neck to define a gap between the first plate and the second plate, and wherein the kennel-shaped head is configured to selectively slide along an axis into the recessed cavity in one of a first installation orientation to provide a first spacing between the first component and the second component and a second installation orientation to provide a second spacing between the first component and the second component.

[0032] In some examples, at least one of the first plate and the second plate is laterally axis geometrically asymmetric.

[0033] In some examples, the kennel-shaped head includes a primary insertion surface associated with the first mounting orientation and a secondary insertion surface associated with the second mounting orientation, wherein the primary insertion surface and the secondary insertion surface are located on opposite sides of the kennel-shaped head.

[0034] In some examples, insertion of the primary insertion surface into the kennel-shaped feature first results in the first mounting orientation and insertion of the secondary insertion surface into the kennel-shaped feature first results in the second mounting orientation.

[0035] In some examples, the kennel-shaped head is rotated about a central axis thereof to switch between the first mounting orientation and the second mounting orientation.

[0036] In some examples, the neck is offset relative to the first plate and centered relative to the second plate.

[0037] In some examples, at least one of the first plate and the second plate includes at least one head alignment channel and at least one head alignment track configured to interface with at least one alignment channel and at least one alignment track associated with the kennel-shaped feature.

[0038] In some examples, the at least one head alignment channel is configured to receive the at least one alignment track when in the first mounting orientation.

[0039] In some examples, the at least one head alignment track is configured to abut the at least one alignment track when in the second mounting orientation.

[0040] In some examples, the second plate includes one or more visual orientation indications to identify the primary insertion surface or the secondary insertion surface.

[0041] Figure 1a and Figure 1b Assembled and disassembled side views of an example fastening system 100 configured to form a connection between a first component 102 and a second component 104, in accordance with aspects of the present disclosure, are respectively shown. Figure 1c and Figure 1dA lower side isometric view of the fastening system 100 in a disassembled state and a lower side isometric view of the fastening system 100 in an assembled state are shown, respectively. The first part 102 and the second part 104 can be, for example, automotive panels. Depending on the application, the first part 102 and the second part 104 can be made of, for example, metal (or metal alloy), synthetic or semi-synthetic polymer (e.g., plastic, such as acrylonitrile butadiene styrene (ABS) and polyvinyl chloride (PVC), etc.), composite material (e.g., fiberglass), or a combination thereof. In the automotive industry, example first parts 102 include, but are not limited to, door trim panels, moldings, appliques, and other substrates (whether used as an interior or exterior surface).

[0042] In operation, an installer selects a desired spacing: either a first spacing (D1) or a second spacing (D2). The kennel head 106a is rotated about the central axis 110 to the corresponding orientation. The kennel head 106a is inserted into the kennel feature 116 by a linear sliding motion in the direction of arrow 122 guided by the geometry of the kennel head 106a and the kennel feature 116. The fastening portion 106b then engages with the second part 104 to complete assembly. In this way, the kennel fastener 106 can accommodate two different spacing configurations without requiring multiple parts or adjustable hardware. This design reduces part count, improves modularity and assembly efficiency, which is particularly beneficial in automotive, aerospace, and modular furniture applications.

[0043] The first part 102 can define an A surface 102a and a B surface 102b (shown as a lower surface). The A surface 102a (also referred to as an A-class surface) is typically a surface that is visible after assembly and, as such, is more aesthetically pleasing (e.g., textured, coated, or otherwise decorated) and typically free of attachment devices and / or related features. In contrast, the B surface 102b (also referred to as a B-class surface) is typically a surface that is not visible after assembly and typically includes various attachment devices and / or related features. In the example shown, the first part 102 defines the kennel feature 116 on the B surface 102b, while the second part 104 defines the opening 118.

[0044] The second part 104 can be, for example, a structural component of a vehicle, such as a door, a pillar (e.g., A-pillar, B-pillar, C-pillar, etc.), an instrument panel component (e.g., cross member, support, frame, etc.), a seat frame, a center console, a fender, a sheet metal frame, etc. The second part 104 can similarly define an A surface 104a and a B surface 104b (shown as a lower surface). After assembly, as most clearly shown in Figure 1b the second part 104 is at least partially covered by the first part 102.

[0045] As shown, a kennel-shaped feature 116 is attached to the B surface 102b, and depending on the material type, can be attached to the B surface 102b after the first component 102 is manufactured (e.g., using an adhesive or a mechanical attachment method, such as the kennel-shaped feature 116 shown). While only a single kennel-shaped feature 116 is shown in the example, it should be understood that multiple kennel-shaped features 116 can be used to couple the first component 102 to the second component 104 depending on the number of fastening points needed between the first component 102 and the second component 104. For example, larger panels typically require multiple fastening points.

[0046] The kennel-shaped fastener 106 is a generally rigid component that generally defines a kennel-shaped head 106a and a fastening portion 106b that extend along a central axis 110. In some examples, a canopy 108 is disposed between the kennel-shaped head 106a and the fastening portion 106b. The kennel-shaped head 106a can be integrally formed with the fastening portion 106b, and where appropriate, with the canopy 108.

[0047] The kennel-shaped head 106a is configured to engage or otherwise attach to the first component 102. In the example shown, the kennel-shaped head 106a generally defines a set of spaced apart flat components (shown as first and second plates 112a and 112b) separated by a neck 114. In the embodiment shown, the first and second plates 112a and 112b are each generally rectangular; however, one or both of the first and second plates 112a and 112b can alternatively be configured into other geometric shapes, such as circular, oval, etc., depending on the desired application and / or shape of the kennel-shaped feature 116. The size and thickness of the plates can be adjusted to accommodate varying load requirements or spatial constraints.

[0048] The kennel-shaped head 106a shown thus includes first and second plates 112a and 112b connected by a neck 114 to define a gap between the first and second plates 112a and 112b. The neck 114 extends between the first and second plates 112a and 112b and integrally connects the first plate to the second plate. The neck 114 shown is cylindrical and ensures that there is a spacing between the first and second plates 112a and 112b to accommodate a feature of the first component 102, such as the kennel-shaped feature 116. The neck 114 is aligned along a central axis 110, which also serves as the central axis of the entire kennel-shaped fastener 106.

[0049] During assembly, a portion of the kennel-shaped head 106a can slide into or into the pocket 120 via a slot 128 defined by the kennel-shaped feature 116. In the illustrated example, the kennel-shaped head 106a can be moved into the pocket 120 in the direction indicated by arrow 122. The slot 128 can be depicted as a keyhole shape and generally includes a substantially circular neck retention segment 128a and a tapered guide segment 128b that guides the neck 114 toward and into the neck retention segment 128a. For example, the first and second plates 112a, 112b are sized and shaped such that the second plate 112b fits in the pocket 120. The cylindrical geometry of the neck 114 also allows for some degree of alignment during installation.

[0050] The fastening portion 106b is configured to engage or otherwise attach to the second component 104. The fastening portion 106b is configured to attach to, embed into, or pass through at least a portion of the second component 104 (e.g., via the opening 118). The opening 118 formed in the second component 104 defines a size and shape that is complementary to the size and shape of the fastening portion 106b such that the fastening portion 106b can be inserted and retained in the opening. In examples, the opening 118 can be substantially circular (e.g., a round hole) and / or a slot (e.g., a narrow rectangular opening).

[0051] The illustrated fastening portion 106b includes a mechanical fastener assembly 124 having an introduction nose 126. The introduction nose 126 can be tapered to facilitate insertion of the distal end of the fastening portion 106b of the kennel-shaped fastener 106 into the opening 118 of the second component 104. The introduction nose 126 serves as a guide for the fastener during engagement.

[0052] Upon assembly, the umbrella 108 is positioned between the first component 102 and the second component 104, as Figure 1b illustrated. In some examples, the kennel-shaped fastener 106 can include a seal to mitigate dust, dirt, and / or moisture from penetrating through the opening 118. The seal can be implemented as a ring (e.g., a ring-shaped structure) and made of a foam material, a thermoplastic, a rubber, etc. For example, the seal can be overmolded onto the umbrella 108 or otherwise attached to the umbrella, or the seal can be configured to fit over the distal end of the kennel-shaped fastener 106 to enclose the portion of the kennel-shaped fastener 106 between the first component 102 and the second component 104 (e.g., adjacent to the umbrella 108). In some examples, the kennel-shaped fastener 106 can include additional features, such as ribs and wings, to mitigate noise and / or rattling between the first component 102 and the second component 104.

[0053] While it is contemplated that the kennel-shaped fastener 106 will be manufactured as an integral component via an injection molding process, other materials and / or processes are contemplated, such as additive manufacturing techniques. Using additive manufacturing techniques, components can be printed with a high degree of accuracy and detail, which is particularly advantageous, for example, in producing components that require complex and / or precise features. Additionally, additive manufacturing techniques do not require the mold machining typically associated with injection molding, thereby reducing upfront manufacturing costs, which is particularly advantageous in small batch production. In some examples, the kennel-shaped fastener 106 can be manufactured with the first component 102 by using material extrusion (e.g., fused deposition modeling (FDM), stereolithography (SLA), selective laser sintering (SLS), material jetting, binder jetting, powder bed fusion, directed energy deposition, VAT photopolymerization, and / or any other suitable type of additive manufacturing / 3D printing process).

[0054] Additive manufacturing techniques print objects in three dimensions, so both the minimum feature size (i.e., resolution) in the X-Y plane (horizontal resolution) and the layer height in the Z-axis (vertical resolution) are considered in the overall printer resolution. The horizontal resolution is the minimum movement the printer’s extruder can make in the X and Y axes within a layer, while the vertical resolution is the minimum thickness of a layer the printer produces in one pass. Printer resolution is described in terms of layer thickness and X-Y resolution in dots per inch (DPI) or micrometers (pm). The diameter of the particles (3D points) in the horizontal resolution can be about 50 pm to 100 pm (510 to 250 DPI). A typical layer thickness (vertical resolution) is about 100 pm (250 DPI), but layers can be as thin as 16 pm (1,600 DPI). The smaller the particles, the higher the horizontal resolution (i.e., the higher the detail the printer produces). Similarly, the smaller the layer thickness in the Z-axis, the higher the vertical resolution (i.e., the smoother the printed surface will be). However, the printing process in higher vertical resolution printing will take longer to produce the finer layers, as the printer has to produce more layers. In some examples, the first component 102 and the kennel-shaped fastener 106 can be formed or otherwise manufactured at different resolutions during the printing operation. For example, depending on the needs of the particular application, the kennel-shaped fastener 106 portion can be printed at a higher resolution than the first component 102, or vice versa.

[0055] Figure 2a and Figure 2b respectively illustrate side and side cross-sectional views of the fastening system 100 in a first installed orientation to provide a first spacing (D1), while Figure 2c and Figure 2d respectively illustrate side and side cross-sectional views of the fastening system in a second installed orientation to provide a second spacing (D2).

[0056] The kennel fastener 106 is configured for use in an adjustable spacing system to selectively provide a first spacing (D1) or a second spacing (D2) between the first component 102 and a second component 104, such as a mating panel, a vehicle body frame, or a structural substrate. The kennel head 106a is configured to be received within the kennel feature 116 in one of two orientations by rotating the kennel fastener 106 180 degrees about the central axis 110. To change the axial height, the kennel head 106a is geometrically asymmetrical along a lateral axis 130 that is perpendicular to the insertion axis (arrow 122) and the central axis 110.

[0057] In an example, the kennel head 106a includes a generally elongated body along the lateral axis 130 having a primary insertion surface 132a (e.g., a first edge) and an opposing secondary insertion surface 132b (e.g., a second edge). As such, when the kennel head 106a is inserted into the kennel feature 116 in a first mounting orientation (Position A), the primary insertion surface 132a faces the back wall of the cavity 120 such that the primary insertion surface is inserted first, thereby resulting in the first spacing (D1). When the kennel head 106a is rotated 180 degrees about the central axis 110 and inserted in a second mounting orientation (Position B), the secondary insertion surface 132b faces the back wall of the cavity 120 such that the secondary insertion surface is inserted first, thereby resulting in the second spacing (D2). This dual orientation spacing capability is achieved through the asymmetrical features of the kennel head 106a and the cavity 120 of the kennel feature 116, which is configured to receive the kennel head 106a regardless of orientation.

[0058] The kennel feature 116 defines a cavity 120 sized and shaped to receive the kennel head 106a through a linear, one-way sliding motion indicated by arrow 122. In particular, the cavity 120 includes parallel side walls 116a, 116b, a bottom wall 116c, and in some cases, a back wall 116d. As shown, the parallel side walls 116a, 116b are spaced apart and bridged by the bottom wall 116c to define the cavity 120.

[0059] Insertion of the kennel-shaped head 106a into the kennel-shaped feature 116 can be guided by alignment rails 134 and alignment channels 140, which are configured to mate with complementary features formed on the kennel-shaped head 106a (e.g., head alignment rails 142a, 142b and alignment channels 138a, 138b). Notably, the alignment rails 134 and alignment channels 140 allow the kennel-shaped head 106a to be inserted in a first mounting orientation (position A) or a second mounting orientation (position B) to adjust the spacing between a first spacing (D1) and a second spacing (D2). The insertion movement (arrow 122) is generally orthogonal to or perpendicular to the main surface of the first component 102 for alignment.

[0060] The kennel-shaped fastener 106 includes two main components: a kennel-shaped head 106a and a fastening portion 106b. The fastening portion 106b is fixedly or integrally connected to the kennel-shaped head 106a. The fastening portion 106b may include any suitable form of mechanical fastener assembly 124.

[0061] Figure 3a and Figure 3b Top and bottom isometric views of the first component 102, which has a kennel-shaped feature 116, are shown respectively. Figure 3c and Figure 3d The top view and bottom view of the first component 102 are shown respectively. Figures 3e to 3h The first side view, second side view, third side view and fourth side view of the first component 102 are shown.

[0062] Figure 3i The first component 102 is shown in detail A. Figure 3e An enlarged side view at (), and Figure 3j The first component 102 is shown along the section line AA ( Figure 3e A cross-sectional view taken from the sample.

[0063] refer to Figure 3i and Figure 3jThe concave cavity 120 includes two parallel alignment rails 134a, 134b formed on the inner surface of the bottom wall 116c. The two alignment rails 134a, 134b shown have the same width. The first and second alignment rails 134a, 134b shown are asymmetrically positioned laterally (i.e., along the lateral axis 130). Specifically, the first alignment rail 134a is spaced apart from the inner surface of the first side wall 116a by a first width (W1), the first rail 134a is spaced apart from the second alignment rail 134b by a second width (W2), and the second alignment rail 134b is spaced apart from the inner surface of the first side wall 116a by a third width (W3). The first, second, and third widths (W1, W2, W3) can each be different (i.e., not equal). In the example shown, the second width (W2) is greater than the first width (W1), which is in turn greater than the third width (W3). The alignment rails 134a, 134b can each include a ramped end 148 to guide the kennel-shaped head 106a during insertion into the concave cavity 120.

[0064] The opposite side (i.e., the outer surface) of the bottom wall 116c includes two parallel alignment channels 140. The first and second alignment channels 140a, 140b shown are asymmetrically positioned laterally. The two alignment channels 140a, 140b shown have different widths. Specifically, the first alignment channel 140a is spaced apart from the outer surface of the first side wall 116a by a fourth width (W4), the first rail 140a is spaced apart from the second alignment channel 140b by a fifth width (W5), and the second alignment channel 140b is spaced apart from the outer surface of the first side wall 116a by a sixth width (W6). The fourth, fifth, and sixth widths (W4, W5, W6) can each be different (i.e., not equal). In the example shown, the fourth width (W4) is greater than the fifth width (W5), which is in turn greater than the sixth width (W6).

[0065] Figure 4a and Figure 4b A top-side isometric view and a bottom-side isometric view of the kennel-shaped fastener 106 are shown. Figure 4c and Figure 4d A top view and a bottom view of the kennel-shaped fastener 106 are shown. Figures 4e to 4h A first side view, a second side view, a third side view, and a fourth side view of the kennel-shaped fastener 106 are shown. Figure 4i A cross-sectional view of the kennel-shaped fastener taken along the cut line B-B Figure 4e ) is shown.

[0066] The kennel-shaped head 106a includes a plurality of features configured to cooperate with the kennel-shaped features 116 and present a first spacing (D1) or a second spacing (D2) based on the desired installation orientation (Position A or Position B).

[0067] Referring to Figure 4i , the first plate 112a includes a plurality of head alignment channels 138b and head alignment rails 142a, while the second plate 112b includes a plurality of head alignment channels 138a and head alignment rails 142b. In the illustrated example, the head alignment channels 138b, head alignment rails 142a, head alignment channels 138a, and head alignment rails 142b are linear and substantially parallel to one another. Further, as shown, when the second plate 112b is centered relative to the neck 114, the first plate 112a is offset such that the neck 114 is not centered relative to the first plate 112a.

[0068] The plurality of head alignment channels 138b and head alignment rails 142a interface with the plurality of head alignment channels 138a and head alignment rails 142b differently depending on the mounting orientation. Referring to Figure 2b , when mounted in the first mounting orientation (Position A), the head alignment channels 138b and head alignment rails 142b are aligned (see contact point A) such that the head alignment rails 142b are received in the head alignment channels 138b, thus reducing the component distance to achieve the first spacing (Dl). Further, the head alignment rails 142b abut the outer surface of the bottom wall 116c of the kennel feature 116 to maintain the first spacing (Dl). Conversely, referring to Figure 2d , when mounted in the second mounting orientation (Position B), the head alignment rails 142a and head alignment rails 142b are aligned such that the head alignment rails 142b abut and rest on the head alignment rails 142a (see contact point B), thus increasing the component distance to achieve the second spacing (D2). Further, the head alignment rails 142b reside in the first and second alignment channels 140a, 140b of the kennel feature 116 to maintain the second spacing (D2).

[0069] The illustrated first plate 112a includes first and second head alignment rails 142b that are laterally asymmetrically positioned on the surface of the first plate facing the second plate 112b. As shown, the first head alignment rail 142b is positioned adjacent to the neck 114, while the second head alignment rail 142b is spaced a distance from the neck 114, with the head alignment channel 138b disposed therebetween. The illustrated first plate 112a also includes first and second head alignment channels 138b that are laterally asymmetrically positioned on the surface of the first plate facing away from the second plate 112b. As shown, the first head alignment channel 138b is positioned adjacent to the neck 114, while the second head alignment channel 138b is spaced a distance from the neck 114.

[0070] The illustrated second plate 112b includes first, second, and third head alignment rails 142b that are asymmetrically positioned laterally on the surface of the second plate facing the first plate 112a. In this example, the first and second head alignment rails 142b are positioned on a first side of the neck 114, while the third head alignment rail 142b is positioned on a second side of the neck 114 opposite the first side.

[0071] As shown, the first head alignment rail 142b is positioned at an edge of the second plate 112b; the second head alignment rail 142b is positioned adjacent the neck 114 and spaced apart from the first head alignment rail 142b by the head alignment channel 138a. The third head alignment rail 142b is positioned at an opposite edge of the second plate 112b and spaced apart from the neck 114 by a distance, with the head alignment channel 138a disposed therebetween.

[0072] To facilitate proper and purposeful orientation of the kennel-shaped head 106a during installation, the kennel-shaped fastener 106 optionally includes one or more visual orientation indicators 144 (or other markings) to identify or distinguish the primary insertion surface 132a and the opposing secondary insertion surface 132b.

[0073] Example indicators 144 include, for example, arrows, symbols, alphanumeric characters, or color-coded regions. The one or more visual orientation indicators 144 can be disposed on the surface of the second plate 112b facing away from the first plate 112a. For example, with reference to Figure 4c , a first directional arrow and a second directional arrow can be embossed or printed on the surface of the second plate 112b, pointing in the direction of insertion for the first installation orientation (Position A) (e.g., the small spacing mode) when the kennel-shaped fastener 106 is rotated to point in the direction of insertion for the second installation orientation (Position B) (e.g., the large spacing mode). Alternatively or additionally, markings such as “high” and “low” can be included on the respective faces to indicate the spacing state. Further, symbols such as triangles or squares can correspond to specific installation tools or assembly instructions. These visual cues help the user select the correct orientation prior to insertion without the need for measuring tools or complex alignment mechanisms. Although the indicators 144 are generally described as being mounted on or associated with the second plate 112b, it is also contemplated that these indicators can be mounted on the first plate 112a. For example, the indicators 144 can be formed along one or more edges of the first plate 112a.

[0074] With reference to Figure 3c , a window 136 can be provided over the kennel-shaped feature 116 (e.g., aligned with the bottom wall 116c) to enable the user to view the one or more visual orientation indicators 144 once installed. The window 136 can be formed in, for example, the first component 102.

[0075] In another example, the visual orientation indicator 144 may be provided in the form of recesses 146a, 146b or other physical marks provided on the primary insertion surface 132a and the opposing secondary insertion surface 132b. (See reference) Figure 2a and Figure 2c The visual orientation indicator 144 is placed on the edge of the second plate 112b (e.g., one of the main insertion surface 132a and / or the opposite secondary insertion surface 132b) so that the user can visually and tactilely confirm the orientation after assembly.
