Embodiments of the present disclosure generally relate to systems and methods of securely retaining a fastener, and, more particularly, to systems and methods of securely coupling a fastener to a substrate.
Various assemblies include panels or objects connected to one another. Automobile assemblies, for example, include various panels and structures connected to other panels or structures, or to the automobile frame itself. Fasteners (such as bolts) are typically used to secure various components together.
In various applications, fasteners of different sizes, shaped, configuration and/or the like are used to secure components together. In order to accommodate longer fasteners and/or fasteners at different positions, metal strips may be spot-welded or a metal spacer may be mechanically crimped to a flanged area of a component in order to thicken a clamped joint under a head of a bolt. As can be appreciated, the welding and/or crimping adds time and cost to a manufacturing process. Moreover, a specialized tool may be needed to secure the fastener to the components.
A need exists for an efficient, cost-effective system and method for accommodating fasteners at a variety of different positions. A need exists for a system and method for capturing a fastener (such as a bolt) and securing the fastener to a component. A need exists for a system and method for capturing a fastener in a component without the need for specialized tooling for installation.
With those needs in mind, certain embodiments of the present disclosure provide a fastener-retaining system that is configured to securely couple a fastener to a substrate. The fastener-retaining system includes a compression-limiting bushing including a tube defining a central passage, and a retainer positioned within the central passage. The retainer includes a first portion that securely connects to the bushing, and a second portion that is configured to securely connect to a portion of the fastener. The retainer is configured to be securely positioned between an interior surface of the bushing and an outer surface of the fastener.
The retainer may include at least one securing member that is configured to securely couple to the substrate. The securing member(s) may include at least one ramped surface and a catch that is configured to latch onto the substrate. The retainer may also include at least one extension leg extending from a retaining wall. The securing member(s) may extend from a distal end of the extension leg(s).
The retainer may include a retaining wall that includes the first portion and the second portion. In at least one embodiment, the retaining wall includes at least one outwardly-extending securing member.
The first portion may include one or more outwardly-directed segments that directly abut into an interior surface of the bushing. The second portion may include one or more inwardly-directed segments that are configured to directly abut into an outer surface of the portion of the fastener. The retaining wall may have a clover shape.
Certain embodiments of the present disclosure provide a securing system that includes a fastener including a head connected to a shaft, and a substrate including a first surface and a second surface opposite from the first surface. A hole is formed through the substrate from the first surface to the second surface. A fastener-retaining system securely couples the fastener to the substrate. The fastener-retaining system includes a compression-limiting bushing including a tube defining a central passage. The bushing is positioned between the head of the fastener and the first surface of the substrate. A retainer is positioned within the central passage of the bushing. The retainer includes a first portion that securely connects to the bushing, and a second portion that is configured to securely connect to the shaft of the fastener.
Before the embodiments of the disclosure are explained in detail, it is to be understood that the disclosure is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The disclosure is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein are for the purpose of description and should not be regarded as limiting. The use of “including” and “comprising” and variations thereof is meant to encompass the items listed thereafter and equivalents thereof as well as additional items and equivalents thereof.
Certain embodiments of the present disclosure provide a fastener retainer, which may be formed of an injection molded plastic or other such material. The retainer may be configured to interact with a drawn metal compression-limiting bushing. The retainer is configured to be securely connected to a bore of the bushing. The bushing is configured to secure a fastener to a substrate, such as piece of sheet metal.
The fastener-retaining system and method may include a bushing and a retainer. The system provides a robust connection to a substrate. The height of the bushing creates an increased amount of initial clamping force that does not need to utilize an additional bushing or spacer. The strength, robustness, and clamping force are due, at least in part, to an increased amount of bolt stretch, for example.
The retainer leads to cost savings for a manufacturer because current known methods of obtaining added bolt stretch are achieved through spot welding large metal strips of thick material and/or mechanically crimping spacers to a flanged area of a component in order to thicken a clamped joint under a head of a bolt.
The retainer may be formed of plastic, and may include an upper portion (such as a main body) that interacts with a fastener and an inner portion of a metal bushing. A segmented or clover-shaped feature may be used to retain the fastener inside the bushing. In at least one embodiment, legs extend below the bottom surface of the bushing. The legs may include snap members that snapably secure into a hole of a substrate. The upper portion of the retainer also allows for the fastener to be presented in a vertically-oriented position, for example.
The fastener 102 may be a bolt, for example. The fastener 102 includes a head 112 connected to a collar 114. A shaft 116 extends from an end of the head 112 and the collar 114. At least a portion of the shaft 116 be externally threaded. The shaft 116 is coaxial with the head 112 and the collar 114. As shown, a lower surface 118 of the collar abuts into an upper edge 120 of the tube 108 of the bushing 106. The shaft 116 of the fastener 102 passes through a central passage of the retainer of the fastener-retaining system 100.
The substrate 104 may be a flat sheet or panel formed of metal, plastic, or the like. The substrate 104 defines a hole (hidden from view in
The fastener-retaining system 100 includes the bushing 106 and the retainer 130 within the interior central passage 132 defined by the bushing 106. The retainer 130 includes a retaining wall 134 that surrounds a circumference of a portion of the shaft 116. The retaining wall 134 includes inwardly-directed segments that abut into an outer surface of the shaft 116. Extension legs 136 extend downwardly from the retaining wall 134. Securing members 138 (such as snaps, ramps, latches, clasps, clamps, or the like) are located at distal ends 140 of the extension legs 136.
The securing members 138 snapably secure to the substrate 104. As the retainer 130 is urged into the hole 126 of the substrate, ramped surfaces 142 of the securing members 138 slide over interior edges of the substrate 104 that define the hole 126. The ramped surfaces 142 inwardly and downwardly cant towards a central longitudinal axis 144 of the fastener-retaining system 100. As the ramped surfaces 142 slide over the interior edges of the substrate 104, the extension legs 136 are squeezed inwardly, due to the diameter of the hole 126 being less than the span between the extension legs 136. As the ramped surfaces 142 are urged past the reduced diameter and engage the ledge 128 (and or underside of the substrate 104), the extension legs 136 flex back to at-rest positions, and a catch 146 (such as a ledge, straight edge, blunt surface, or the like) of the ramped surface 142 securely latches onto the ledge 128, thereby securely coupling to the substrate 104.
When the securing members 138 are secured to the substrate 104 as described, an upper edge of the retainer 130 may abut into a portion of the fastener 102, such as the the lower surface 118 of the collar 114. Further, the bushing is compressively trapped between the upper surface 122 of the substrate 104 and the portion of the fastener 102, such as the lower surface 118 of the collar 114. Portions of an outer surface 150 (such as outwardly-directed segments, as described below) of the retainer 130 may abut into an interior surface 152 of the bushing 106. In this manner, the bushing 106 securely couples to the retainer 130. Further, the bushing is securely clamped between the head 112 of the fastener 102 and the upper surface 122 of the substrate 104.
An interior surface 163 of the retaining wall 134 defines a central passage 164 into which the shaft 116 of the fastener 102 passes. In at least one embodiment, interior surfaces of the inwardly-directed segments 162 are threaded and threadably engage exterior threaded portions of the shaft 116.
As shown in
The extension legs 136 may combine to define an outer envelope 166 having a diameter that is less than a span 168 between opposed outwardly-directed segments 160 of the retaining wall 134. The diameter of the envelope 166 may be equal to or less than the diameter of the hole 126, while the span 168 may be larger than the diameter of the hole 126. As such, the retaining wall 134 may be too large to fit into the hole 126 of the substrate 104.
As the retainer 130 is urged into the hole 126, the ramped surfaces 142 lead the extension legs 136 into the hole 126. As the retainer 130 is urged into the hole 126, the extension legs 136 inwardly deflect, as described above, until the catches 146 abut into the ledges 128 of the substrate 104, at which point the extension legs 136 flex back to (or towards) at rest-positions.
As shown in
The bushing 106 securely couples to the retainer 130 by way of the outwardly-directed segments 160 abutting into interior surfaces of the bushing 106. The inwardly-directed segments 162 securely couple to the shaft 116 of the fastener 102. Further, the securing members 138 secure to the substrate 104, such as by snapably or latchably securing to edge areas that define the hole 126. In this manner, the fastener-retaining system 100 securely retains the fastener 102, and securely clamps to the substrate 104.
Referring to
The fastener-retaining system 100 provides an efficient, cost-effective system for accommodating fasteners at different heights and positions relative to the substrate 104. The fastener-retaining system 100 captures the fastener 102 and couples the fastener 102 to the substrate 104 without the need for separate tools. That is, an individual may couple the fastener-retaining system 100 to the fastener 102 and the substrate 104 by hand.
The hole 126 of the substrate 104 may have a uniform diameter throughout its length. The securing members 138 of the retainer 130 securely latch onto a portion of the lower surface 124 surrounding the hole 126. As shown, gaps 190 may exist between the outwardly-directed segments 160 of the retainer 130 and the shaft 116. As described above, the inwardly-directed segments 162 (shown in
