Description
- This is a division of U.S. patent application Ser. No. 09/478,314 filed on Jan. 6, 2000, which is incorporated by reference herein.
- The present invention relates to an apparatus and method for fastening and, more particularly, to an apparatus and method for fastening objects flush to a surface.
- Large networked computer systems require a substantial number of printed circuit cards to perform a countless variety of tasks. The printed circuit cards are typically housed within a plurality of rectangular boxes, which are commonly referred to as a chassis or a main carrier of components. The chassis are then loaded into the system having a cabinet like structure which is configured to receive and support a number of chassis. The chassis are generally inserted laterally and stacked one on top of the other. Each chassis has at least one exposed end where a cable is inserted so that the printed circuit cards can interface, for example, with an SP computer system. The cabinet like structure can also expose two ends of the rectangular chassis so that a cable can connect with, for example, a 390 computer system.
- The cabinet like structure provides an area defined only slightly greater in length, width and height than the chassis itself. As a result, the chassis cannot have any protrusions or extensions, such as a screw head or other securement devices, located on its outer surface. A screw head can actually prevent the chassis from properly loading into the structure. Moreover, and if the chassis cannot be inserted into the structure then the computer system cannot interface with the printed circuit cards. Consequently, if the printed circuit cards or components are secured in the chassis, then the securement device must be flush to the outer surface of the chassis.
- Other alternatives such as using adhesives, employing screws and even welding are labor intensive and do not provide a convenient removable means for securing printed circuit cards flush to the outer surface of the chassis.

- Referring now to FIGS. 1-4, a
mounting structure 10 constructed in accordance with the present invention is shown.Structure 10 has amounting cover 12.Cover 12 preferably is constructed out of steel or any other type of sheet metal.Cover 12 has a plurality of retention slots oropenings 16 in anupper surface 18.Cover 12 is configured to have a pair ofside portions 20 and anend portion 22.Side portions 20 andend portion 22 are positioned to extend downwardly fromupper surface 18.Side portions 20 also have a plurality ofapertures 24 for mountingcover 12 preferably to a chassis containing a printed circuit board (not shown).Apertures 24 are formed in mountingcover 12 by a two step process and can be generally defined as follows: holes are punched out ofcover 12, which displace excess material; then, the hole is struck a secondtime creating aperture 24 with chamferred sides for receiving screws. This second hit, which creates the chamferred sides of the aperture, is referred to as a countersink.Cover 12 is also configured to have anedge 27. - A
partition 32 is configured, dimensioned and positioned to provide additional support to mounting cover 12 (FIG. 1).Partition 32 includes atop portion 34 and abase portion 36 for mounting it to cover 12 atapertures 24 and the chassis, respectively. - A pair of
openings 17 are positioned and located to accommodate the positioning of partition 32 (FIGS. 1 and 2). Alternatively,partition 32 can be centered underneathcover 12, placed off centered to either the left or right underneathcover 12, and/or placed at the anterior or open end ofcover 12 or posterior atend portion 22 ofcover 12.Partition 32 can likewise extend the entire length ofcover 12 or just a portion of it as required by the dimensions outlined in the engineering documents (drawings, specifications, etc.). Moreover, a plurality ofpartitions 32 can be used (FIG. 2).Partition 32 is constructed from the same materials as mountingcover 12 as well as other suitable durable materials such as plastics and metal alloys containing steel.Cover 12 can also be configured, dimensioned and positioned, when mounted, to not requirepartition 32 for support. - Mounting
cover 12 can be manufactured from materials such as metals or metal alloys, but preferably steel or an alloy containing steel.Cover 12 can also be scaled in size and thickness to accommodate different geometric configurations. However, the thickness ofcover 12 is limited by the stamping process used to create the plurality ofopenings 16. Mountingcover 12 preferably is approximately 57.3 cm long and approximately 19.5 cm wide; however, cover 12 can be constructed and dimensioned as required by its specific application. - Referring now to FIGS. 3-4, plurality of
openings 16 are formed using a “swaging” process and can be generally defined as follows: a hole having an “H” like configuration is stamped incover 12 using a device or a manually operated tool (FIG. 3), then the narrow portion of the “H” like configuration is “swaged” or stamped a second time with a device or a manually operated tool to create plurality of openings 16 (FIG. 4). Plurality ofopenings 16 are adapted to receive a plurality of male fasteners orengagement members 52 ofsecurement members 28. Onceengagement members 52 are received within plurality ofopenings 16, the position ofopenings 16cause securement members 28 to be arranged in a uniform manner. Once fully engaged withinopening 16, the positioning and configuring ofsecurement members 28 define a plurality of receiving areas 102 (FIG. 1). - Referring now to FIG. 2, in one embodiment plurality of
openings 16 are equally spaced from each other and define two rows ofopenings 16 inupper surface 18 of mounting cover 12 (FIG. 2). Of course, and as contemplated in accordance with the instant application, the location, size and configuration ofopenings 16 may vary. For example, the configuration ofsecurement members 28, such as the length, width and size of anengagement member 52 or a portion extending fromsecurement member 28, will affect the position of plurality ofopenings 16. Referring now to FIG. 4, plurality ofopenings 16 are further defined to each have a receivingopening 40, a second portion or anengagement opening 42, and a first portion or astaking opening 44. - A pair of
tab portions 46 extend intoopenings 16 and are in a facing spaced relationship so as to define engagement opening 42 (FIG. 4). Tab portions are located intermediate receivingopening 40 and stakingopening 44.Tab portions 46 are also chamferred so as to have anengagement surface 48.Engagement surface 48 provides a male fastener supporting means within an angular configuration (FIG. 4). Upon insertion ofengagement members 52 intoopenings 16,engagement opening 42 supportsengagement members 52 withinopenings 16. - A portion of receiving
opening 40 is defined by a pair ofsidewalls 50 in a facing spaced relationship. Pair ofsidewalls 50 are positioned to depend angularly inwardly to each other to promote smooth engagement ofengagement members 52 withinopenings 16 asengagement members 52 slide in the direction ofarrow 98 as indicated by the dashed lines in FIG. 9. Stakingopening 44 includes aback edge 49 or a stop surface that preventsengagement member 52 from sliding any further in the direction ofarrow 98. In the exemplary embodiment, opening 16 is approximately 2.8 cm-4.0 cm long. Both receivingopening 40 and stakingopening 44 are approximately 0.75 cm (0.30 in.) wide. Engagingopening 42 is approximately 0.264 cm (0.10 in.). However, plurality ofopenings 16 including receivingopening 40, engagingopening 42 and stakingopening 44 again may be scaled in size and configured to receiveengagement members 52 of different lengths, widths and shapes. - Referring now to FIGS. 5-8,
securement members 28 as well assecurement member 30 each have a pair ofengagement members 52, or portions extending fromsecurement members 28 andsecurement member 30, which are received and engaged by plurality ofopenings 16.Engagement members 52 can be positioned anywhere along the top ofsecurement members 28 andsecurement member 30 in accordance with the design specifications required for the desired application. In addition, 28, 30 each have a pair of cut-securement members outs 53.Securement members 26 can be manufactured with as many cut-outs 53 as required (FIGS. 5 and 7). The significance of cut-outs 53 will be discussed further in the specification. -
Securement members 28 andsecurement member 30, andengagement members 52, preferably are constructed from extruded aluminum which possesses malleable qualities, or other metals possessing similar malleable qualities including but not limited combinations or alloys containing aluminum and other malleable metals.Securement members 28 andsecurement member 30 are first extruded and then undergo secondary machining to createengagement members 52.Engagement members 52 also possess the same malleable qualities ofsecurement members 28 andsecurement member 30. In the preferred embodiment,engagement members 52 are configured to have atop portion 54 wider than abase portion 56, which are defined by a pair ofside portions 58 extending angularly inward (FIGS. 5-8). - In the exemplary embodiment,
securement members 28 are approximately 14.5 cm (5.71 in.) long, 0.87 cm (0.34 in.) wide at its base and stands approximately 1.45 cm (0.571 in.) tall. In the exemplary embodiment,securement member 30 is approximately 14.5 cm (5.71 in.) long and approximately 1.47 cm (0.579 in.) wide at its base and stands approximately 1.45 (0.571 in.) cm tall. In the exemplary embodiment,engagement members 52 are approximately 1.00±0.05 cm (0.394±0.02 in.) long and have a width less than the width of both receivingopening 40 and stakingopening 44. However, bothsecurement members 28 andsecurement member 30, as well asengagement members 52, can be constructed in accordance with the design specifications of the desired applications so that the length, width and height ofsecurement members 28 andsecurement member 30 can vary as well as the length, width and shape ofengagement members 52. - Referring now in particular to FIG. 6,
securement member 28 has afirst sidewall 60 depending downwardly from the top ofsecurement member 28. Alongitudinal shoulder 62 is depends outwardly fromfirst sidewall 60. Asecond sidewall 64 depends downward fromlongitudinal shoulder 62. Abase portion 66 depends outwardly fromsecond sidewall 64.Securement member 28 also has a flankingfirst sidewall 68 depending downwardly from the top ofsecurement member 28. A first slantedsidewall 70 depends downward and angled inward from flankingfirst sidewall 68. A flankingsecond sidewall 72 depends downwardly from first slantedsidewall 70. A second slantedsidewall 74 depends outwardly and angled from flankingsecond sidewall 72. A flankingbase portion 76 depends outwardly from second slantedsidewall 74. - Referring now in particular to FIG. 8,
securement member 30 has afirst sidewall 80 depending outwardly from the top ofsecurement member 30. Alongitudinal shoulder 82 depends outwardly fromfirst sidewall 80. Asecond sidewall 84 depends outwardly fromlongitudinal shoulder 82. Abase portion 86 depends outwardly fromsecond sidewall 84. A flankingfirst sidewall 88 depends downwardly from the top ofsecurement member 30. Aceiling 90 depends inwardly from flankingfirst sidewall 88. A flankingsecond sidewall 92 depends downwardly fromceiling 90. Abase portion 94 depends outwardly from flankingsecond sidewall 92.Securement member 30 is configured to accommodate the position ofpartition 32 as well as define a portion of receivingarea 104. - Referring now to FIG. 9,
engagement members 52 are first inserted through receivingopenings 40 in a first direction shown by anarrow 96. During the insertion ofengagement members 52,top portion 54 does not rise aboveupper surface 18 of mountingcover 12.Top portion 54 ofengagement members 52 remain level withupper surface 18 of mountingcover 12.Securement members 28 are then repositioned in a second direction indicated by anarrow 98 so thatengagement members 52 are now positioned withinengagement opening 42 and stakingarea 44. Engagement surfaces 48 make contact with and positively grip theside portions 58 ofengagement members 52 assecurement members 28 slidably engageengagement openings 40 in the second direction shown byarrow 98. The positioning and configuration ofside portions 58 andengagement surfaces 48 keepengagement member 52 at or belowupper surface 18. Onceengagement members 52 are repositioned,top portions 54 are always level withupper surface 18 ofcover 12. - Referring now to FIGS. 10-11, once
engagement members 52 are positively gripped by engagingopening 42,engagement members 52 now rest in engagingopening 42 and stakingopening 44. A downward force is applied in a direction depicted by anarrow 100 toareas 101 of eachtop portion 54 ofengagement members 52. An apparatus or a device such as a press equipped with a hammer, or a person using a hammer, applies the downward force as illustrated by ahammer 55 in FIG. 10. The hammer is configured to strikeareas 101 and can resemble a split fork with two separate and distinct striking surfaces as shown in FIG. 10. When applied, such a pair of striking surfaces simultaneously strikeupper surface 54 ofengagement members 52 and deflect the malleable material ofengagement member 52 atareas 101. - As
engagement member 52 is forced downward in the direction ofarrow 100, a portion ofengagement member 52 is forced into portions of staking opening 44 (FIGS. 10-11). Stakingopening 44 possesses a width larger than the width of engagingmembers 52. Prior to engagingmembers 52 being forced downward into stakingopening 44, an open space or unoccupied portion exists on either side of that part of engagingmember 52 within staking opening 44 (FIG. 10-11). - As
areas 101 of engagingmember 52 are forced downwardly, portions of engagingmember 52 remain supported by engagingsurfaces 48 of engaging opening 42 (FIGS. 10-11). However, the part ofengagement member 52 located in stakingopening 44 and without engagement surfaces 48 for support are forced into the open or unoccupied portions of staking opening 44 (FIG. 4). Onceengagement members 52 are forced into stakingarea 44,engagement members 52,securement members 28, andsecurement member 30 are all prevented from being repositioned again. Accordingly,engagement members 52 are now fastened flush to cover 12. -
Fastening engaging members 52 to cover 12 in this manner is referred to as a self-fixturing method. Typically, before two parts can be joined, a separate tool is specifically designed and implemented to hold each part in place. Once the two parts have been secured, fastened, adhered, etc. together by another device or tool, the separate tool designed to hold the parts in place is removed. This process is referred to as fixturing. - In the present invention, a separate tool is not required to hold
securement members 28 orsecurement member 30 in place within mountingcover 12 prior to applying the engaging force in the direction ofarrow 100; thus, the method is referred to as self-fixturing. Onceengagement members 52 slidably engageopening 16 andengagement opening 42 positively support sidewalls 58 ofengagement members 52,securement members 28 remain in place within mountingcover 12.Securement members 28 do not require further alignment or a separate tool to hold them in place within mountingcover 12 prior to applying the engaging force in the direction ofarrow 100. As a result, the method for insertingsecurement members 28 intoopenings 16 is a self-fixturing process. Additional benefits, such as time and cost efficient and not as labor intensive, are realized since designing, manufacturing and using a special tool is not required. - As illustrated in FIGS. 1 and 12, once
engagement members 52 ofsecurement members 28 are fixedly secured withinopenings 16 of mountingcover 12,securement members 28 are positioned to define a receivingarea 102. Flankingfirst sidewall 68 and first slantedsidewall 70 ofsecurement members 28 are in a facing spaced relationship withfirst sidewall 60 of the opposingsecurement members 28. Flankingsecond sidewall 68 ofsecurement members 28 are in a facing spaced relationship with a portion offirst sidewall 60 as well aslongitudinal shoulder 62 andsecond sidewall 64 of the opposingsecurement members 28. Flankingsecond sidewall 74 and second slantedsidewall 76 ofsecurement members 28 are in a facing spaced relationship with asecond sidewall 64 of anothersecurement members 28.Securement members 28 define a receivingarea 102 having the configuration illustrated in FIG. 12. - As illustrated in FIGS. 1 and 13, once
securement member 30 is fixedly secured to mountingcover 12,securement member 28 andsecurement member 30 are positioned to define a receivingarea 104 whenengagement members 52 are fixedly engaged within 16 and 17, respectively. Flankingopenings first sidewall 88 and an upper portion of flankingsecond sidewall 92 ofsecurement member 30 are in a facing spaced relationship withfirst sidewall 60 andsecond sidewall 64 of securement member 28 (FIG. 13). The rest of flankingsecond sidewall 92 ofsecurement member 30 is in a facing spaced relationship withsecond sidewall 64 of securement member 28 (FIG. 13). -
Securement member 30 has an area defined byceiling 90, flankingsecond sidewall 92 andbase portion 94 which is considerably larger in size than an area defined by first slantedsidewall 70, flankingsecond sidewall 72, second slantedsidewall 74 andbase portion 76 ofsecurement member 28.Securement member 30 is also wider thansecurement member 28; however,securement member 30 is shorter in length thansecurement member 28.Securement member 30 has a larger area, a greater width and a shorter length because it is located behindpartition 32.Securement member 30 must be wider then partition 32 so thatsecurement member 30 can define a receivingarea 104.Securement member 28 andsecurement member 30 define a receivingarea 104 having the configuration illustrated in FIG. 13. - Again referring to FIGS. 12-13,
securement members 28 are configured to define a plurality ofopenings 105 in between each 66, 76 ofbase surface portions first securement member 28 and 86, 94 ofbase surface portions second securement members 30. - Referring now to FIGS. 14-15, receiving
102, 104 define a geometry specific to a card carrier. Such a card carrier preferably is an actuator 106 containing aareas card 108.Actuator 106 is molded plastic and fastened tocard 108 usingshoulder screws 110 located in opposingslots 112 found on actuator 106 (FIG. 14). This allowsactuator 106 to move independently ofcard 108.Card 108 can encompass any type of electronic interposer card having different functions such as wrapping signals generated from circuitry to fiber optics. Additionally,card 108 can also be a “blank”, which is a plastic card used to occupy a space (FIG. 15).Actuator 106 is laterally inserted into receiving 102, 104.areas Actuator 106 is guided by ashoulder 114 located on either side ofactuator 106. Opposingshoulders 114 are supported byfirst sidewall 60,longitudinal shoulder 62,second sidewall 64 andbase portion surface 66 ofsecurement member 28 and engages flankingfirst sidewall 68 of opposingsecurement member 28. - Once
card 108 reaches an interface mechanism (not shown), shoulder screws 110 ofactuator 106 are automatically aligned with cut-outs 53 ofsecurement members 28 andsecurement member 30. At thispoint card 108 can no longer move forward in either receiving 102 or 104.area Actuator 106 is then pushed forward causingcard 108 to slide at an angle within opposingslots 112.Card 108 moves downward in a vertical direction.Card 108 then mates blind with interface mechanism in a camming action asactuator 106 reaches the end ofslots 112.Card 108 is now fastened flush to the chassis. - When
actuator 106 is laterally inserted into receivingarea 104,actuator 106 is again guided by opposingshoulders 114, which is supported bybase portion 94 ofsecurement member 30 and engagesfirst sidewall 60,longitudinal shoulder 62,second sidewall 64 andbase portion 66 of opposingsecurement member 28. Bothactuator 106 andcard 108 engage receivingarea 104 and interfacing mechanism, respectively, in the same manner as when laterally inserted into receivingarea 102. In this preferred embodiment of the present invention, onceactuator 106 andcard 108 are laterally inserted into receiving 102 and 104, a retainingareas bar 116 is fixedly attached to the end ofcards 108 and edge 27 ofcover 12. The retainingbar 116 shields electromagnetic emissions emanating from the operation of the electronic equipment and prevents mountingstructure 10 from becoming conductive. - Referring now to FIG. 16, as contemplated and in accordance with the present invention, an alternative embodiment of
cover 12 can further include anend portion 22 having a pair ofapertures 118 and aflange 120, which extends outwardly fromend portion 22. Agasket 122 is mounted to the top offlange 120 by an adhesive found ongasket 122. In this alternative embodiment,gasket 122 is an emc gasket commercially available from Parker Hannafin Seal Group, Irvine, Calif.Gasket 122 seals electromagnetic emissions emitted from the printed circuit board. Pair ofapertures 118 are adapted to receive a screw or similar securement means to secure a separate cover placed uponchassis 26 to complete the enclosure and ensure correct air flow. - Accordingly, and as contemplated in accordance with the present invention, a mounting structure scalable in size for fastening objects flush to a surface, large or miniature, may be configured to receive various guidance mechanisms having different geometries. Therefore, the present invention provides a most economical and spatially conservative means for fastening objects flush to a surface.
- While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention may not be limited to the particular embodiment disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
