- FIG. 8 illustrates a partial cross-sectional view of the bushing assembly 50 .
- the fastener 52 includes a head 54 integrally formed with a shaft 56 including a threaded area 58 .
- An annular ring 59 outwardly extends from the shaft 56 above the threaded area 58 . If the fastener 52 shifts upwardly with respect to the bushing 30 , the annular ring 59 abuts against or into the lobes 42 .

- the lobes 42 may extend from the leading end 36 to the trailing end 38 over the entire length of the bushing 30 .
- the fastener 52 is effectively captured or otherwise retained by the bushing 30 because the lobes 42 of the inwardly-flanged trailing end 38 surround the outer surfaces of the shaft 56 of the fastener 52 .
- the shaft 56 is captured about the trailing end 38 , but maybe free with respect to the leading end 36 .
- the fastener 52 may shift or pivot about the interface of the shaft 56 and the trailing end 38 in the directions of arc A.

- the fastener 52 may be easily located with respect to a hole of a component.
- the bushing 30 automatically centers the fastener 52 due to the fact that the fastener 52 is centered and/or captured at the trailing end 38 of the bushing 30 . It has been found that while the fastener 52 may shift or pivot during a hole or passage locating process, the securing process automatically corrects any shift and centers the fastener 52 due to the fact that the fastener 52 is surrounded by the bushing 30 at the trailing end 38 .
- FIG. 9 illustrates a cross-sectional view of the bushing 30 being positioned within a component 60 according to an embodiment of the present invention.
- the component 60 defines an opening 62 into which the bushing 30 passes.
- a small gap 63 exists between outer surfaces of the leading end 36 and interior walls 64 that define the opening 62 . Any plastic flash protruding from the component 60 may be collected within the gap 63 .
- the bushing 30 may be easily located and initially positioned within the opening 62 . The bushing 30 may be dropped into the opening 62 without the interior walls 64 interfering with the bushing 30 .
- the ribs 40 and 41 securely anchor into the interior walls 64 of the component 60 .
- the ribs 40 and 41 press into the interior walls 64 , thereby providing a secure fit between the bushing 30 and the component 60 .
- the bushing 30 is anchored into the component 60 at areas proximate the ribs 40 and 41 , instead of an interference fit between the entirety of the bushing 30 and the interior walls 64 .
- the bushing 30 causes little stress to the component 60 .
- the ribs 40 and 41 provide a low stress press fit with respect to the component 60 .
- FIG. 10 illustrates a close-up view of the leading end 36 of the bushing 30 within the component 60 .
- an outer surface 70 of the leading end 36 of the bushing 30 is coined, rolled, folded, or otherwise rounded.
- the leading end 36 is not susceptible to digging into or snagging the interior wall 64 of the component 60 . Instead, if shifted into the interior wall 64 , the smooth, rounded outer surface 70 of the leading end 36 slides over the interior wall 64 .
- FIG. 11 illustrates a front view of the bushing assembly 50 positioned within the component 60 .
- the ribs 40 and 41 act to securely center the bushing 30 within the component 60 . That is, while the leading end 36 , which has a smaller diameter than the opening formed in the component 60 , may shift inside the component 60 during a locating process, the ribs 40 and 41 center and anchor the bushing 30 within the component as the bushing 30 is urged into the component 60 .
- the distal end 72 of the fastener 52 may shift or pivot about the interface of the shaft 56 and the trailing end 38 of the bushing 30 .
- the process of locating the fastener 52 with respect to a hole or opening of another component is made easier.
- the shape of the bushing 30 allows plastic of the component 60 to creep or otherwise slowly flow around the drawn ribs 40 and 41 after insertion. This assists in retaining the bushing 30 firmly in position.
- FIG. 12 illustrates a partial cross-sectional view of the bushing assembly 50 securing components 60 and 80 together according to an embodiment of the present invention.
- the component 80 includes an opening 82 into which the distal end 72 of the fastener 52 is located and retained. During the locating process, the distal end 72 may shift or pivot, as discussed above, in order to make it easier to position the fastener 52 within the opening 82 .
- the bushing assembly 50 automatically aligns and centers the fastener 52 with respect to the components 60 and 80 . That is, if the fastener 52 is shifted during the locating process, the shift is corrected during the securing process.
- the fastener 52 shifts 5° along arc A, that shift is reversed as the fastener 52 is tightened.
- the leading end 36 abuts the top surface of the component 80 , thereby automatically aligning the fastener 52 within the opening 82 . If the leading end 36 is angled with respect to the top surface of the component 80 during the locating process, the leading end 36 automatically becomes flush with that top surface as the threaded area 58 of the fastener 52 continues to threadably engage reciprocal surfaces of the component 80 that surround the opening 82 .
- FIG. 13 illustrates a front view of a bushing 90 according to an embodiment of the present invention.
- the bushing 90 is similar to the bushing 30 shown in FIG. 5 , except that the trailing end 92 is outwardly flanged, forming a wider base on which a fastener may rest. Additionally, slots 94 are formed in the bushing 90 proximate the outwardly flanged training end 92 .
- the cut material is then canted inwardly and downwardly to form fastener engaging members, such as canted tabs 96 .
- fastener centering tabs 96 is less material used to form the fastener centering tabs 96 than the lobes 42 (shown in FIGS. 6 and 8 ).
- FIG. 14 illustrates a top view of the bushing 90 .
- the inwardly canted fastener centering tabs 96 act to center a fastener shaft within the central passage 97 of the bushing 90 .
- the outwardly flanged trailing end 92 forms a wider base 98 for a fastener head to abut.
- FIG. 15 illustrates a partial cross-sectional view of a bushing assembly 100 according to an embodiment of the present invention.
- the bushing assembly 100 includes the bushing 90 and a fastener 102 having a fastener head 104 integrally connected to a shaft 106 having a threaded portion 108 and annular ring 110 above the threaded portion 108 .
- the outwardly flanged trailing end 92 provides the wide base 98 that supports the head 104 .
- the fastener centering tabs 96 are inwardly and downwardly canted so as not to dig into the shaft 106 .
- the fastener centering tabs 96 act to snag the annular ring 110 , as discussed above, if the fastener 102 upwardly shifts.
- leading end flange 112 may be larger than those described above.
- the enlarged leading end flange 112 increases bearing surface area with respect to the fastener and a component into which the bushing 90 is positioned.

Description
- This application relates to and claims priority benefits from U.S. Provisional Patent Application No. 60/872,834 entitled “Bushing Assembly,” filed Dec. 5, 2006, which is hereby incorporated by reference in its entirety.
- Embodiments of the present invention generally relate to a bushing assembly, and more particularly to a bushing assembly (which may be formed through drawn metal or other types of fabrication) configured to securely retain a fastener, such as a bolt.
- In various applications, bushings are used when securing components together. For example, a bushing may be used with a bolt to secure a first component, such as a plastic housing cap, to a second component, such as a work-piece to which the housing cap is configured to be secured. Typically, the bushing is positioned within a hole of the first component and a screw or bolt is passed through the bushing to secure the first component to the second component.

FIG. 1 illustrates a cross-sectional view of a known bushing 10 being positioned within acomponent 12. Thebushing 10 is generally cylindrical and includes aninner passage 14 configured to receive a fastener, such as a bolt or screw. A leadingend 16 of thebushing 10 is positioned with ahole 18 formed in thecomponent 12. The leadingend 16 of thebushing 10 includes straight walls that are configured to be pressed into thecomponent 12 and provide an interference fit withinterior walls 20 of thecomponent 12 that define thehole 16. -
FIG. 2 illustrates a cross-sectional view of the known bushing 10 andbolt 22 being positioned within thecomponent 12. Thebolt 22 is positioned within theinner passage 14 of thebushing 10 such that ahead 24 of thebolt 22 is supported by atrailing end 26 of thebushing 10. Because the outer walls of the bushing 10 interfere with theinterior walls 20 of thecomponent 12, frictional forces resist movement of thebushing 10 into thehole 18. Thus, a relatively large amount of force may be needed to secure thebushing 10 andbolt 22 in place with respect to thecomponent 12. During this securing process, thebushing 10 may damage theinterior walls 20 of thecomponent 12. Moreover, the force needed to secure thebushing 10 andbolt 22 in place stresses thecomponent 12 about thehole 18. If thecomponent 12 is plastic, thecomponent 12 may crack, snap or otherwise break due to the stress caused by the securing force. -
FIG. 3 illustrates a close-up view of the leadingend 16 of the known bushing 10 abutting theinterior walls 20 of thecomponent 12. As shown inFIGS. 1-3 , the outer diameter of the leadingend 16 of thebushing 10 is about the same size as, or larger than, the diameter of thehole 18. During insertion of thebushing 10 into thehole 18, the leadingend 16 provides an edge that may snag theinterior walls 20, thereby causing more stress and damage to thecomponent 12. For example, the sharp leadingend 16 may scrape, scratch, or otherwise dig into theinterior walls 20, thereby making insertion of the busing 10 into thehole 18 more difficult. -
FIG. 4 illustrates a cross-sectional view of the known bushing 10 fully secured within thecomponent 12. As noted above, the process of inserting thebushing 10 into thecomponent 12 stresses thecomponent 12. Additionally, as shown inFIG. 4 , ashaft 28 of thebolt 22 does not abut any portion of thebushing 10. Thus, thebolt 22 may shift with respect to bushing 10 before, during and after the securing process. A bolt moving within thebushing 10 may make alignment of thebushing 10 and bolt with respect to components more difficult. - Embodiments of the present invention provide a bushing that is easily positioned within a component. Embodiments of the present invention provide a bushing that is safely and securely anchored with respect to a component. Further, embodiments of the present invention provide a bushing that is less susceptible to damaging the component during an insertion process.
- Certain embodiments of the present invention provide a bushing that includes a cylindrical main body having a leading end and a trailing end, wherein a fastener passage is defined within the main body, and a plurality of ribs outwardly extending from the main body. The plurality of ribs are configured to securely position the bushing with respect to an opening formed in a component.
- An outer surface of the leading end may be rounded in order to prevent snagging, scraping or otherwise damaging the component.

FIG. 5 illustrates an isometric view of abushing 30 according to an embodiment of the present invention. Thebushing 30 may be formed of hardened thin wall material, which is in contrast to various conventional bushings that are formed from rolled thick wall material or solid stock. Thus, thebushing 30 is lighter than conventional bushings, while exhibiting similar strength. - The
bushing 30 may be configured to be pushed into a molded hole of a component, or injection molded in place. Thebushing 30 includes a generally cylindricalmain body 32 defining aninterior passage 34 that extends from a leadingend 36 to a trailingend 38. Thebushing 30 is configured to be positioned within an opening, hole, passage or the like a component, such as a plastic cap or the like. A series of stepped 40 and 41 outwardly extend from theribs main body 32. As shown inFIG. 5 , two series ofribs 40 are shown. One series includes horizontally alignedribs 40, while the other series includes horizontally alignedribs 41. The first series ofribs 40 are positioned a distance away from the leadingend 36 while the second series ofribs 41 are positioned a distance away from the trailingend 38. More or less series or ribs than those shown may be used. -
FIG. 6 illustrates a top plan view of thebushing 30. Thebushing 30 includes a series of inwardly-directedlobes 42. Thelobes 42 extend inwardly from themain body 32 toward theinterior passage 34. As shown inFIG. 6 , thebushing 30 may include threelobes 42 equally spaced from one another. Thelobes 42 are configured to securely retain a shaft of a bolt within the interior passage. Thelobes 42 may be positioned at or proximate the leading and trailing ends 36 and 38, respectively. More orless lobes 42 than those shown may be used. Optionally, thelobes 42 may uniformly extend over the entire surface of the interior walls of thebushing 30. - As also shown in
FIG. 6 , the bushing includes four ribs 41 (and 40, which are hidden from view inFIG. 6 ) equally spaced about an outer surface of themain body 32. Each rib 41 (and 40) may be spaced 90° from the nextclosest rib 41. As shown inFIG. 6 , the diameter D1 spanning the distally locatedribs 41 is greater than the diameter D2 of the trailingend 38. Alternatively, more or less ribs 41 (and 40) at varying spacing may be used than those shown inFIG. 6 . -
FIG. 7 illustrates a front view of abushing assembly 50 according to an embodiment of the present invention. Thebushing assembly 50 includes afastener 52, such as a screw or bolt, positioned within the interior passage 34 (shown inFIGS. 5 and 6 ) of thebushing 30. -
FIG. 8 illustrates a partial cross-sectional view of thebushing assembly 50. Thefastener 52 includes ahead 54 integrally formed with ashaft 56 including a threadedarea 58. Anannular ring 59 outwardly extends from theshaft 56 above the threadedarea 58. If thefastener 52 shifts upwardly with respect to thebushing 30, theannular ring 59 abuts against or into thelobes 42. As such, thelobes 42 prevent thefastener 52 from ejecting from thebushing 30 through the interaction with theannular ring 59. Thehead 54 is supported by the trailingend 38. - The leading and trailing ends 36 and 38, respectively, are inwardly flanged. The
lobes 42 extend into theinterior passage 34. Thelobes 42 of the inwardly-flanged trailingend 38 abut outer surfaces of theshaft 56, thereby securely centering thefastener 52 in place with respect to thebushing 30, and, as noted above, preventing thefastener 52 from ejecting from thebushing 30 by engaging theannular ring 59 of the fastener 52 (if thefastener 52 shifts upward with respect to the bushing 30). Alternatively, thelobes 42 of the inwardly-flangedleading end 36 may also abut outer surfaces of theshaft 56. While only the leading and trailing ends 36 and 38, respectively, are shown to be inwardly-flanged inFIG. 8 , other portions of thebushing 30 may also include inwardly-directed lobes. For example, thelobes 42 may extend from the leadingend 36 to the trailingend 38 over the entire length of thebushing 30. - The
fastener 52 is effectively captured or otherwise retained by thebushing 30 because thelobes 42 of the inwardly-flanged trailingend 38 surround the outer surfaces of theshaft 56 of thefastener 52. As shown inFIG. 3 , theshaft 56 is captured about the trailingend 38, but maybe free with respect to theleading end 36. As such, thefastener 52 may shift or pivot about the interface of theshaft 56 and the trailingend 38 in the directions of arc A. In this way, thebolt 52 remains securely positioned within thebushing 30, yet the distal end of thefastener 52 may shift during an alignment process with respect to a component, such as a work-piece. Thus, thefastener 52 may be easily located with respect to a hole of a component. Further, when thefastener 52 is secured to the work-piece, thebushing 30 automatically centers thefastener 52 due to the fact that thefastener 52 is centered and/or captured at the trailingend 38 of thebushing 30. It has been found that while thefastener 52 may shift or pivot during a hole or passage locating process, the securing process automatically corrects any shift and centers thefastener 52 due to the fact that thefastener 52 is surrounded by thebushing 30 at the trailingend 38. -
FIG. 9 illustrates a cross-sectional view of thebushing 30 being positioned within acomponent 60 according to an embodiment of the present invention. Thecomponent 60 defines anopening 62 into which thebushing 30 passes. As shown inFIG. 9 , asmall gap 63 exists between outer surfaces of theleading end 36 andinterior walls 64 that define theopening 62. Any plastic flash protruding from thecomponent 60 may be collected within thegap 63. Because the diameter D2 of theleading end 40 is smaller than the diameter D3 of theopening 62, thebushing 30 may be easily located and initially positioned within theopening 62. Thebushing 30 may be dropped into theopening 62 without theinterior walls 64 interfering with thebushing 30. Little to no effort is used to drop thebushing 30 into an initial position with respect to theopening 62. This is in stark contrast to conventional bushings that require a relatively large and constant insertion force. Once thebushing 30 is initially positioned such that theribs 40 abut atop surface 66 of thecomponent 60, an increased amount of force is used to push thebushing 30 into theopening 62 in the direction of arrow B. The ends 68 of the ribs 40 (and 41) are rounded and smooth. Thus, the 40 and 41 do not dig, scrape, damage or overly stress theribs component 60 during the insertion process. - As the
bushing 30 is pressed into thecomponent 60 in the direction of arrow B, the 40 and 41 securely anchor into theribs interior walls 64 of thecomponent 60. The 40 and 41 press into theribs interior walls 64, thereby providing a secure fit between thebushing 30 and thecomponent 60. Thebushing 30 is anchored into thecomponent 60 at areas proximate the 40 and 41, instead of an interference fit between the entirety of theribs bushing 30 and theinterior walls 64. Thus, it has been found that thebushing 30 causes little stress to thecomponent 60. Overall, the 40 and 41 provide a low stress press fit with respect to theribs component 60. -
FIG. 10 illustrates a close-up view of theleading end 36 of thebushing 30 within thecomponent 60. As shown inFIG. 10 , anouter surface 70 of theleading end 36 of thebushing 30 is coined, rolled, folded, or otherwise rounded. Thus, the leadingend 36 is not susceptible to digging into or snagging theinterior wall 64 of thecomponent 60. Instead, if shifted into theinterior wall 64, the smooth, roundedouter surface 70 of theleading end 36 slides over theinterior wall 64. -
FIG. 11 illustrates a front view of thebushing assembly 50 positioned within thecomponent 60. The 40 and 41 act to securely center theribs bushing 30 within thecomponent 60. That is, while the leadingend 36, which has a smaller diameter than the opening formed in thecomponent 60, may shift inside thecomponent 60 during a locating process, the 40 and 41 center and anchor theribs bushing 30 within the component as thebushing 30 is urged into thecomponent 60. - As discussed above, the
distal end 72 of thefastener 52 may shift or pivot about the interface of theshaft 56 and the trailingend 38 of thebushing 30. Thus, the process of locating thefastener 52 with respect to a hole or opening of another component is made easier. - The shape of the
bushing 30 allows plastic of thecomponent 60 to creep or otherwise slowly flow around the drawn 40 and 41 after insertion. This assists in retaining theribs bushing 30 firmly in position. -
FIG. 12 illustrates a partial cross-sectional view of thebushing assembly 50 securing 60 and 80 together according to an embodiment of the present invention. Thecomponents component 80 includes anopening 82 into which thedistal end 72 of thefastener 52 is located and retained. During the locating process, thedistal end 72 may shift or pivot, as discussed above, in order to make it easier to position thefastener 52 within theopening 82. As thefastener 52 is tightened, thereby securing the 60 and 80 together, thecomponents bushing assembly 50 automatically aligns and centers thefastener 52 with respect to the 60 and 80. That is, if thecomponents fastener 52 is shifted during the locating process, the shift is corrected during the securing process. Thus, if during the locating process, thefastener 52 shifts 5° along arc A, that shift is reversed as thefastener 52 is tightened. For example, as thefastener 52 is tightened, the leadingend 36 abuts the top surface of thecomponent 80, thereby automatically aligning thefastener 52 within theopening 82. If the leadingend 36 is angled with respect to the top surface of thecomponent 80 during the locating process, the leadingend 36 automatically becomes flush with that top surface as the threadedarea 58 of thefastener 52 continues to threadably engage reciprocal surfaces of thecomponent 80 that surround theopening 82. -
FIG. 13 illustrates a front view of abushing 90 according to an embodiment of the present invention. Thebushing 90 is similar to thebushing 30 shown inFIG. 5 , except that the trailingend 92 is outwardly flanged, forming a wider base on which a fastener may rest. Additionally,slots 94 are formed in thebushing 90 proximate the outwardlyflanged training end 92. The cut material is then canted inwardly and downwardly to form fastener engaging members, such as cantedtabs 96. Thus, less material is used to form thefastener centering tabs 96 than the lobes 42 (shown inFIGS. 6 and 8 ). -
FIG. 14 illustrates a top view of thebushing 90. As shown inFIG. 14 , the inwardly cantedfastener centering tabs 96 act to center a fastener shaft within thecentral passage 97 of thebushing 90. As noted above, the outwardly flanged trailingend 92 forms awider base 98 for a fastener head to abut. -
FIG. 15 illustrates a partial cross-sectional view of abushing assembly 100 according to an embodiment of the present invention. Thebushing assembly 100 includes thebushing 90 and afastener 102 having afastener head 104 integrally connected to ashaft 106 having a threadedportion 108 and annular ring 110 above the threadedportion 108. As shown inFIG. 15 , the outwardly flanged trailingend 92 provides thewide base 98 that supports thehead 104. Thefastener centering tabs 96 are inwardly and downwardly canted so as not to dig into theshaft 106. Moreover, thefastener centering tabs 96 act to snag the annular ring 110, as discussed above, if thefastener 102 upwardly shifts. - Additionally, the
leading end flange 112 may be larger than those described above. The enlargedleading end flange 112 increases bearing surface area with respect to the fastener and a component into which thebushing 90 is positioned. -
FIG. 16 illustrates a partial cross-sectional view of abushing assembly 120 according to an embodiment of the present invention. Thebushing assembly 120 includes abushing 122 and afastener 124, similar to those described above. However, the trailingend 126 of thebushing 122 includes a spring-biasedflange 128 that adjusts when thecomponent 130,bushing 122 and/orfastener 124 thermally expand and/or when thefastener 124 is over-torqued. For example, if thecomponent 130 and/orbushing 122 expands, the spring-biased flange flexes accordingly to ensure that thebushing 122 and thefastener 124 remain secured within thecomponent 130. Similarly, if thefastener 124 is over-torqued, the spring-biasedflange 126 may flatten out to accommodate the over-torqued condition. - Additionally, instead of lobes or cut-out portions, the
bushing 122 may include fastener engaging members that areindented portions 132. Theindented portions 132 may be formed by crimping or other such methods. Theindented portions 132 act to center and secure thefastener 124 similar to the lobes 42 (shown inFIGS. 6 and 8 ) and the fastener centering tabs 96 (shown inFIGS. 13-15 ). -
FIG. 17 illustrates a front view of abushing 140 according to an embodiment of the present invention. As shown inFIG. 17 , thebushing 140 includes only one series ofribs 142, but may include more than those shown. Additionally, thebushing 140 includes a wide trailingend flange 144. -
FIG. 18 illustrates a top view of thebushing 18. The trailingend flange 144 is rolled over itself and then atri-lobe shape 146 is drawn on top. The rolled, drawn tri-lobeshape 146 is an optional way of forming lobes or fastener-centering members that center and capture a fastener (as discussed above). -
FIG. 19 illustrates a partial cross-sectional view of a bushing assembly 150 according to an embodiment of the present invention. As shown inFIG. 19 , the trailing end flange is rolled over itself and drawn to form a base for thefastener head 160 and also thetri-lobe shape 146 that is configured to center thefastener shaft 162 and latching onto theannular ring 164 if theshaft 162 shifts upward. -
FIGS. 20 and 21 illustrate top and front views, respectively, of abushing 200 according to an embodiment of the present invention. Thebushing 200 is similar to thebushing 90 shown and described with respect toFIGS. 13-15 , except that thebushing 200 includes a split-column design that provides a higher tolerance. That is, agap 201 is formed in thecolumn 202 of thebushing 200. Thegap 201 allows thecolumn 202 to expand and contract. When thebushing 200 is positioned around a component, such as a fastener, thegap 201 allows thecolumn 202 to radially expand to fit around the component. Once thecolumn 202 is positioned around the component, the column flexes back. As shown inFIG. 21 , the gap 21 extends over the height (or length, depending on the orientation) of thebushing 200. - Thus, embodiments of the present invention provide a bushing that is easily positioned within a component. The ribs of the bushing securely anchor the bushing within the component. Additionally, the bushing is not susceptible to damaging the component during an insertion process. Further, the bushing securely retains and centers a fastener therein.
