Additionally, in many applications, the distance between the overhead and lower track changes somewhat during construction. The ceiling and/or floor may sag, for example, as construction loads are placed on them. To accommodate such changes, one or the other end of a stud may be initially attached with a temporary fastener. After a construction event has shifted the ceiling and/or floor, the temporary fastener is removed and replaced with a permanent fastener with the stud now in a deflected position as compared to its original position.

  • a stud 52 is attached to a first metal track 54 and a second metal track 56 using attachment clips 58.
  • Both the metal stud 52 and metal tracks 54 and 56 are generally U-shaped, with a planar base portion 60 and two opposing sidewalls 62 and 64 that extend normally from the base portion 60.
  • the stud 52 and tracks 54, 56 may have other shapes, with examples including (but not limited to) a stud having a rectangular or "capital I" profile.
  • the present clip is not limited to use with studs and tracks of any particular shape.

  • the flat base portion 60 of the overhead track 56 is suitable for mounting on an overhead substrate, which may be, for example, a concrete, metal or wood ceiling.
  • the stud 52 is dimensioned to fit within the U- shaped tracks 54 and 56.
  • the studs and tracks 52-56 are typically made of a thin sheet metal. Other materials are also contemplated, including polymer, paperboard, and the like. The present invention is not limited to use with studs and tracks made of any particular material.
  • FIGS. 4-6 illustrate the example attachment clip 58 of FIGS. 2-3 in greater detail.
  • the clip 58 is L-shaped and includes a mounting portion or plate 80 that is generally flat and coplanar with the track base portion 60 (FIGS. 2, 3) for mounting thereon.
  • the plate 80 is generally square shaped, although many other shapes could be used, with examples including a rectangular shaped.
  • the plate 80 may be dimensioned as desired. It should be sufficiently large to provide positive engagement with the base portion 60 (FIGS. 2, 3). hi many applications, the plate 80 is dimensioned to have an area in the general range of 0.5 - 0.75 in 2 . This range offers useful area for engaging the track base portion 60 and for resisting rotation or other movement. Other sizes are contemplated.
  • a passage 82 extends through the plate 80.
  • a fastener 84 preferably a nail or pin, is held in the passage 82.
  • the nail 84 includes a head 86 and a cap 88 over a tip, which is sharp and pointed to facilitate insertion into a substrate.
  • a positioning flute 90 is optionally included on the shaft of the nail 84 for positioning the nail in the barrel of a driving tool such as a combustion or pneumatic driver gun (not illustrated).
  • the flute 90 is a collar made of flexible plastic with fins extending outward to engage the driver gun barrel.
  • Other fasteners in addition to the nail 84 may be used, with examples including screws, bolts, adhesives and the like.
  • a crush dimple or boss 92 surrounds the passage 82.
  • the boss 92 is configured as a circular ridge or dimple that is useful to prevent the nail head 86 from penetrating through the plate 80 when driven with a large force as is common in installation tools of the type discussed above.
  • the crush dimple flattens when the nail head 86 impacts it, thereby absorbing some force from the nail insertion.
  • the crush dimple 92 may also provide some rigidity and resistance to bending of the plate 80.
  • the nail 84 can be used to attach the attaching clip 58 to the tracks 54 and 56 (FIGS. 2, 3) and to the underlying substrate (e.g., concrete floor, ceiling). Further, the nail 84 may also be effective to hold the track 54, 56 in place on the substrate. Put another way and with reference to FIG. 2, attaching the clip 58 to the track 54 may also be effective for fixing the clip 58 on the track 54 and fixing the track 54 onto the underlying substrate. Labor efficiency is thereby gained in that only one nail 84 need be used to accomplish two tasks. Further, including the nail 84 held in the passage 82 and together with the positioning flute 90 is useful to accommodate one handed operation.
  • the example clip 58 includes a pair of locking fingers 100 and 102 that rise at an angle of about 90° from the mounting plate 80.
  • the fingers 100 and 102 are configured to engage the stud 52 (FIGS. 2, 3) and hold it in place.
  • the fingers 100 and 102 may engage opposing sides of the stud base portion 60 to thereby hold it between them and restrain it from movement in the direction of the track major axis TMA (FIG. 2).
  • example clip 58 includes a pair of locking fingers, other numbers of fingers may be provided, with three, or four being contemplated. More fingers generally enhance holding power, but too great a number of fingers may result in cumbersome engagement with the stud 52. Two to three fingers are believed to be most useful for typical applications, although other numbers may be useful for other applications.
  • the fingers 100 and 102 are spaced apart from one another by some distance in a direction that lies along the axis labeled as Y in the overhead view of FIG. 5. This separation defines a first slot 104 between the fingers 100 and 102.
  • the slot 104 in the example clip 58 extends for some distance onto the mounting plate 80. It should be understood that the slot 104 need not extend onto the mounting plate 80, but may be coextensive with the height of the fingers 100 and 102 (along the Z axis of FIG. 6) or may extend for only a portion of the height of the fingers 100 and 102. It is also contemplated to omit the slot 104, with the fingers 100 and 102 instead directly adjacent to one another.
  • the two fingers 100 and 102 are also separated from one another by some distance in the direction along the axis labeled as X in FIG. 6, which is coincident with the track major axis TMA of FIG. 2.
  • This separation defines a second slot 106 visible in the elevational view of FIG. 6.
  • This slot 106 is configured to facilitate engagement with the stud 54 (FIGS. 2, 3). It may be dimensioned, for example, to provide positive engagement with the stud base portion 60.
  • known commercial tracks and studs are made of metal having a thickness of between about 0.017" and 0.022". Providing a slot 106 with a width along the X axis of FIG.
  • variations of the present attachment clips of the invention include a plurality of locking fingers that are not offset from one another in the X direction of
  • FIG. 6 That is, on some example clips, no slot 106 is defined.
  • FIG. 7 illustrates one such attaching clip 120 which includes a mounting plate 122 and a pair of locking fingers 124 rising therefrom at an angle of about 90°.
  • the locking fingers 124 have top ends 126 that are spread apart or splayed from one another in the direction of the X / track major axis to form a V shape that facilitates engagement with the stud.
  • the clip 120 provides advantages of low cost of manufacture and easy, nested stackable shipment and storage.
  • the locking fingers 124 are optionally coplanar and/or joined when the clip 120 is manufactured and shipped. A user could then bend the fingers 124 apart from one another into the V shape to receive the stud 52. The locking fingers 124 can then be bent back towards one another to more firmly hold the stud 52 in place.
  • FIG. 8 illustrates one such example clip 130 which includes two locking fingers 132 joined to one another.
  • a separation or perforation line 134 lies between the two locking fingers 132.
  • the perforation line 134 may be a complete or partial cut. In either case, the perforation line 134 allows for ease of separation and bending apart of the locking fingers 132 by a user in the field.
  • the locking fingers 132 also include bent engagement lips 136 for facilitating engagement with the stud 52. Although only two locking fingers 124 and 132 are illustrated in FIGS. 7 and 8 respectively, other example clips in these general configurations may include other numbers, with an example being three.
  • the fingers 100 and 102 have different heights along the Z axis (which is normal to the track major axis TMA) of FIG. 6 as needed for particular applications. Different heights for the fingers 100 and 102 are useful to ease engagement with the stud 52.
  • the stud 52 may be placed in contact with the longer locking finger 100 which may then be deflected somewhat to allow for easy sliding downward (toward the mounting plate 80) into the slot 106 and engagement with the shorter locking finger 102.
  • the difference in height between the locking fingers 100 and 102 may be set as desirable. In many applications, a difference in height of at least about 0.125" is useful to allow for easy engagement with the stud 52. Other height differentials may also be useful, with a second example being at least about 0.25".
  • Other alternate embodiments for the present clips 58 include locking fingers having the same height.
  • both locking fingers have a height of at least about 0.25".
  • the height should be sufficiently large to allow some movement of the stud 52 along the height of the locking finger 100, 102 (i.e., in the Z direction of FIG. 6).
  • locking fingers 100 and 102 that are configured to hold the stud 52 (FIGS. 2, 3) in place but allow for some vertical movement (i.e., in the Z direction of FIG. 6) offer useful benefits and advantages.
  • a stud was often initially attached to an overhead track using a temporary fastener. Installation of a ceiling or other construction events often caused the stud to deflect some amount relative to the overhead track. In such cases, the temporary fastener was removed and a second permanent fastener attached with the stud in its new, deflected position. This resulted in two fastener installations and one removal, which entails additional labor and other costs.
  • the present clip 58 as well as many depicted alternatives are useful for reducing or eliminating these duplicative labor and other costs.
  • Some of the present attachment clips are configured to hold the stud 52 in place but to allow some movement in the vertical direction (i.e., the direction normal to the track major axis and along the Z axis of FIG. 6). This allows for the stud 52 to be initially attached using a clip 58, 120, 130, etc. to an overhead track without the need for subsequent replacement or adjustment when a ceiling is installed or some other construction event occurs and results in some deflection of the stud. Substantial savings are thereby realized. Different amounts of movement may be allowed in this Z direction depending on the configuration of the locking fingers 100 and 102.
  • configuring the locking fingers 100 and 102 to allow for some vertical movement of the stud 52 include, for example, providing them in sufficient height along the Z axis of FIG. 6. The height should not be so large, on the other hand, that installation of the stud 52 is cumbersome or difficult. Heights of between about 0.375" and about 0.625" are believed to be useful in many applications.
  • the locking fingers 100 and 102 should have a width (i.e., along the Y axis of FIG. 5) sufficient to provide positive engagement with the stud 52 and to resist stud rotation. Widths of each finger 100 and 102 of about 0.25" or more are useful in many applications. Other sizes will be useful in other applications, including lesser widths.
  • the present attachment clips 58, 120, 130 may be made of any suitable material which can be selected based on considerations of strength, ease of use, ease of manufacture, cost, resistance to corrosion, and the like. Some applications may call for more strength than others. For example, some applications may include placing the vertical stud 52 under higher loads in the direction of a track major axis than others. In many applications, the load on the studs in this direction is not high. In such applications relatively thin and lightweight clips may be used. Metals such as a tin, rolled steel, alloys, and polymers are example suitable materials.
  • the clips as shown in FIGS. 2-8 offer some advantages related to their manufacture since they can generally be fabricated from die cutting or stamping of a single rectangular piece of metal.
  • the locking fingers 100, 102 can be bent into desired position using a tool or the like.
  • the example attachment clip 58 is made of thin rolled steel having a thickness of about 0.010", and may be made in a single piece and then formed through die cutting and bending. Other thicknesses of steel may also be used. This has been found to provide cost and strength advantages that are useful in many applications. Manufacture in a polymer process through the use of molds may also be useful.
  • FIGS. 9-10 illustrate an additional example attachment clip 150 of the invention.
  • the clip 150 is similar in many respects to the clip 58 (FIGS. 2-6). It includes a mounting portion in the form of a flat mounting plate 152 and an attaching portion in the form of three locking fingers 154, 156 and 158.
  • the three locking fingers 154, 156 and 158 are offset from one another in the direction illustrated as the X axis in FIG. 10, which is coincident with the track major axis TMA of FIG. 2.
  • the center locking finger 156 is offset from the first and third locking fingers 154 and 158 to define a slot 160 therebetween.
  • the slot 160 is configured to engage a portion of the stud 52 (FIGS. 2-3). This may include, for example, dimensioning the width of the slot 160 along the X direction to be about the same or slightly larger than the wall thickness of a stud. Examples include widths of the slot 160 that accommodate one or both of
  • slot 160 width of from about 0.017" - 0.022
  • some additional width e.g., about 0.05
  • the width of the slot 160 may be set slightly larger than the wall thickness of the stud 52 for ease of insertion into the attachment clip. Or, in other example clips, the width of the slot 160 may be very close to or even slightly less than the stud wall thickness for a tighter engagement. Configuring the locking fingers 154, 156 and 158 to result in a width of the slot 160 that is smaller than the stud wall thickness may cause the locking fingers 154, 156, 158 to exert a spring gripping force on the stud. While this may be desirable in some applications, in other applications a looser fit may be preferred to facilitate, for example, allowing for vertical movement of the stud 52 (i.e., in the direction of the Y axis of FIG. 6).
  • the locking fingers 154 and 158 include upper ends that are defined by an engagement lip 162.
  • the engagement lip 162 bends outward in a direction away from the second or center locking finger 156 to facilitate insertion of the stud into the slot 160. Put another way, the engagement lips 162 result in the slot 160 having an enlarged upper entrance and narrowing towards the mounting plate 152.
  • the engagement lip 62 generally comprises an upper portion of the locking fingers 154 and 158 bent in a direction away from the center finger 156.
  • Other engagement lips are contemplated and will be apparent to those knowledgeable in the art, including the lips 136 of FIG. 8. Unlike the example clip 58 of FIGS.
  • the locking fingers 154, 156 and 158 of the clip 150 have substantially equal heights along the Z direction of FIG. 10. Although locking fingers 154, 156 and 158 of differing heights could alternatively be used, the use of the engaging lips 162 eases entry of the stud into the slot 160.
  • the clip 150 of FIGS. 9-10 also includes a generally square and planar mounting plate 152. Unlike the mounting plate 80 of the clip 58 of FIGS. 5-6, no passage is provided. Although an alternate configuration of the clip 150 may include a passage for receiving a nail, screw or other fastener, the configuration as shown is also useful. Also, the clips 58, 120, 130 and others, may be provided with mounting plates without a passage. Such a configuration can be used, for example, in applications where attachment of the clip 150 to a track (such as the track 54 or 56 of FIG. 2) is accomplished using an adhesive or other mechanism that does not include a penetrating fastener.
  • An adhesive may be applied, for example, to a bottom surface 164 of the mounting plate 152 and/or the track base portion 60 (FIGS. 2, 3) to hold the attaching clip 150 in place. This may be advantageous, for example, in applications where use of a nail, screw, or other penetrating fastener is not desirable. Suitable adhesives include glues, caulks, and the like.
  • One example clip 150 is provided with an adhesive layer on the mounting plate bottom surface 164 underlying a removable protective strip. At time of use, the protective strip can be removed and the clip attached.
  • Other examples include the use of mating mechanical fasteners, such as mating hook and loop materials including the commercial VELCRO ® product. A strip of such material can be attached to the track, and a corresponding mating patch of material attached to the plate underside 164. This can be useful, for example, to allow for adjustable placement of the clip 150 on the track 54, 56.
  • the attachment clip 150 may also be used with a nail, screw or other penetrating fastener.
  • the fastener may be driven through the mounting plate 152.
  • a nail gun may be used, for example, to drive a nail through the mounting plate 152 to hold the clip 150 in place on a track and/or an underlying substrate. Or, a passage can be provided to ease attachment.
  • FIG. 11 illustrates still an additional example attachment clip 190 of the invention.
  • the clip 190 is consistent in many respects the clips 58, 120, 130, 150. It includes a mounting plate 192 with a passage 194, and three locking fingers 196, 198, and 200.

That is, although two engagement arms 306 have been illustrated, other embodiments may include only a single engagement arm 306.
  • FIG. 19 illustrates still an additional attachment clip 350 which includes a mounting plate 352 and an attachment portion in the form of an attachment plate
  • the plate 354 is an alternative to locking fingers of other embodiments.
  • the clip 350 may be used to hold a stud in place by applying adhesive (shown hidden) to a surface 358 of the attachment plate 354 that will contact the stud 52.
  • the mounting plate 356 can be attached to the track base portion 60 using adhesive, a fastener, or the like.
