Abstract

RESILIENT RUNNER FOR WALL CONSTRUCTION

ABSTRACT OF DISCLOSURE

A resilient sheet metal runner for attaching wallboard to a supporting structure comprising a base attaching flange having a resilient web coextensive therewith and integral with a longitudinal edge thereof with a support portion integral with an opposite edge of the resilient web and a stop flange integral with the opposite edge of the support portion.
The base flange is disposed in a first plane, the flexible web is disposed in a second plane at an obtuse angle to that of the base flange and with respect to a third plane represented by the support portion. The stop flange extends at an obtuse angle toward the first plane in a fourth plane which it occupies hut is of less width than the resilient web so that it does not extend into the first plane. The resilient web is slotted for increased flexibility and the base attaching flange is provided with laterally offset fastener tabs to space the attaching flange from the supporting structure and thus obtain further improvement in the prevention of transmission of vibrations impinging on the wallboards mounted on the sheet metal runners.

Description

BACKGROUND OF ~HE IN~tENTION
Wall framing of two by ~our support members i5 com~on in the usual wall or ceiling constructions. In wall~oard type of wall and ceiling construc~ion the 2~ x 4~ support members support and are covered by gypsum wallboard which may be a single layer of gypsum wallboard or of two ply construction consisting of a gypsum backing board surfaced with a iayer of gyp5um wallboard~ Such structure is widely used because it ls strong, inexpensive and readily fabricated.
Its use in apartment buildings and multi-unit constructions has been more or less restricted because of its lower resistance to the transmission of sound and thereby fails to secure the privacy preferred by occupants of such building~O Attempts have been made to solve this problem and one such method utilizes a staggered stud system. In this system the supporting studs are staggered so that they are spaced and arranged in ,, such manner that alternate support mem~ers are coplanar , while adjacent support members are offset relative to each ~, other. In the two separate opposed rows of support members one row thus supports the wallboard on one side of the wall while the other row of support members support the wallboard , . . .
~ on the other si~e of the wall. Each side o~ the wall structure ; is thus pennitted to vibrate independently and there~ore substantially independent acoustically. One drawback to I such construction is that it requires twice the number of ,~ support members normally used and thus results in a substantial ;~ increase in expenseO Furthermore, this system cannot be adapted for practical applications in ceiling structure.
Another prior method comprises a slotted stud system ~; 30 wherein each support member is slotted along its length, , ; ~

except at its end, to divide the support into two portions separated by a space. This permits the two portions to resonate substantially independently and thus be substantially independent acoustically. Wallboard is applied to such slotted supports as in the usual partition or wall system.
~` A disadvantaqe of this slotted stud sys~em is that care must be exercised when applying the wallboard so that the fasteners are not driven through the space between slotted portions in~o the opposite portion and thus destroy the ability of the two portions to resonate independently. Also, such :
slotted construction cannot be utilized in ceiling structuresO
: ~
ResilieDt metal runners have also been used heretofore, and in one such system a plurality of resilient runners are attached to the support members in spaced relationship and disposed to receive wallboard attached thereto. Each suah runner comprises an elongate member of sheet metal provided with a base flange secured to the support members and a support surface element of sufficient width to provide for ::, attachment of the meeting edges of adjoining wallboard panels by suitable fasteners. A resilient portion at one edge of the support surface interconnects the support surface with the base flange and thus serves to space the .support surface and the attached wallboard from the support members.
A stop flange element was disposed along the opposite edge of the support surface element and extended at an angle toward the support members and served to support the support ~ surface element when the wallboard was being applied thereto ; as by the driving of fasteners. In this runner, the base ; flange is directly secured to the support member by suitable

fas~eners, thus any reduction in the transmission of vibra-tions is attained solely by the amount of resiliency along the interconnection between the base and support ~lange~O
SUMMA.RY OF THE INVENTION
The present invention provides a resilient runner which ~` may be used with wa~l structures or ceiling constructions, and are such, when installed on the support members, as to provide level coplanar supporting surfaces for application of gypsum boards on the wall and ceiling structures and thus 0 afford smooth surfaces. The resilient runners are spaced apart and since the standard wallboards are four feet in width the spacing of the runners will be about two feet so that the gypsum wallboard can then be applied horizontally or vertically, and thereby take advantage of the flexibility thus afforded in constructing the walls and ceilings. The i resiIient runners are fully capable of being applied at any desired spacing to utilize wallboards of different widths.
Each re~ilient metal runner, as herein contemplated, comprise~
; an elongate sheet metal runner specifically adapted for ` 20 attaching wallboard to a supporting structure preferably - on both sides thereof, in resiliently spaced relation, so as to prevent sound waves impinging against the wall surfaces from being transmitted directly to tha support structure and thus ~ . .
1 to the opposite wallboard. The vibrations induced in the :,~ .
, wallboards will be ultimately dispersed and absorbed 80 that little, if any, vibration will be transmitted through the support structure. The vibrations are damped and diffused ; in their travel through the resilient metal runner~ interposed between the support structure and the wall~oard applied on ., .:. .

A resilient web is integral along one edge with the adjoining edge of the base flange and lies in a second plane at an obtuse angle to - the first plane in which the base flange lies. A support portion ` lying in a third plane inclined with respect to the second plane ~' in which the resilient web lies has one edge co~xtensive with the opposite edge of the resilient web and extends laterally in an offset position relative to the base flange. The support portion is disposed substantially parallel to the base flange.
A stop flange is coextensive with the opposite edge of the `, support portion and extends outwardly in an inclined plane toward the support members but this flange is shorter than the distance between the support portion and the support members so that the free edge of the stop flange is spaced rom the support members.

a support portion 15 of the metal runner 13 to secure ~he gypsum board in placeO The metal runner 13 is secured to tlle upright supporting members 10 through a base flange 16 by means of fastenings 17, which are here shown as nails drive~ through the base 1ange 16 into each of the supporting members 10 to securely mount the metal runners upon opposite sides of the : ~. .
supportinq members in the desired spacing and relationship to support the attached gypsum boards in properly spaced relation.
The resilient sheet metal runner 13 includ~s a resilient ~ 10 web 18 integral along one continuou.--i edge thereof with the ; ~ adjoining edge of the base flange 16. ~he base flange on each ~ runner 13 is disposed in one plane, which as here disclosed, -- is substantially vertical adjoining the respective faces of the supporting members 10. The resilient web 18 however, lies ` in a second plane inclined at an obtuse angle to the first!:

also to the first plane defined by the base flange 16.
A stop flange 19 is integral w~th and coextensive with the opposite edge of the support portion 15 and is inclined relative to the support portion and ~xtends at an angle toward the ~irst plane represented by the base flange 16 on ~he support-ing members 10 i~ut stops short of th~ supporting members so that the terminal, or free end of the stop flange is spaced from the members 10 leaving the metal runner 13 free to deflect and to .~lex as afforded by the resilient web ~8 but adapted to contact the supporting members 10 when defleated under the force of driving the fasteners 14 thus preventing the East~ners from being driven into the members 10 and defeating the purpose of the flexibility provided by the runner to absorb vibrations and thereby prevent transmission of sound waves. Upon contact of the free end of the stop flange 19 with the supporting members 10 the support por~ion 15 of the metal runner will be prevented from further deflection toward the members 10 thereby enabling the .
screws 14 to be driven through the support portion 15 without penetrating the supporting members.
In the ~orm of the invention illustrated in FIGS. 1, 2 and 3 the sheet metal resilient runner includes structure for securing the base attaching flanqe 16 to the supporting memhers 10 in a manner whereby a greater degree of in~lllation of the supporting ,:~"

6Z~3 supporting structure in spaced relation from the supporting members 10 thereby to reduce the ~ransmission of such vibrations through the wall structure. The base attaching flange 16 is secured to the supporting members 13 by the fastenings 17 but this securement is by means of offset fastening plates 24, each containing a nail hole 25, ~hrough which the fastenings 17 are dri~en into the supporting members 10.
The fastening plates 24 are displaced laterally f~om ~he plane of the base attaching flange 16, as best illustrated in , FIG. 3, so that, when installed, the attaching flange is disposed in spaced relation from the supporting members 10 by the amount of the offset represented by the connecting strip 26 extending between the base flange 16 and each of the fastening i "; plates 24. The fastening plates 24 are disposed in groups :` of three at longitudinally spaced intervals throughout the ~$
; lengtl of the sheet metal runner 13 so that some lengthwise :
adjustment of the metal runner may be had in mounting them on the supporting members 10. This spacing of the groups of plates 24 is such as to be compatible wi~h the usual spacing of studs in wall and partition structures which is generally standardized at approximately sixteen inches. However, in the form herein disclosed the groups of fastening plates 24 are spaced on eight , inch centers to provide a greater range of adaptability while conforming with the standard stud spacing.
In the modified form of the invention illustrated in FIGS. 4 and 5 the general structure of the sheet metal stringer 13 is identical with the form of the metal runner shown in ,. . . .
FIGS. 2 and 3, including the base attaching flange 16, the ;~ support portion 15, the flexible web 18 internally connecting the base flange and support portion, the openings 2~ in the resilient web and the stop f1an~e 19 at the opposite edge of ......

the s~pport portion. The offset fastening plates 27 however, are integrally connected with the base flange 16 at opposite ends of each such plate members by connecting strips 28. The offset plates 27 are disposed in multiples o~ three at longi tudinally spaced intervals similar to the spacing o~ th~ spacing tabs 24 in FIGS. 2 and 3 and in the form of the invention shown in FIGS. 4 and 5 the offset plates 27 ar~ each provided with the nail hole 25 for receiving the fastenings 17 attaching the sheet metal runner 13 to the supporting members 10.
The form of the invention illustrated in FIGS. 6 and 7 is similar to that shown in the preceding Figures, but the offset plates 29 are continuous across each group of three nail holes 25 and are ~ntegrally connected at respectively opposite ends of each such continuous plate with the base flange 16 by means of similar connecting strip~ 30. Otherwise, the arrangement functions in similar manner to the forms of the invention revealed by other Figures. The lateral spacing of the base flange 16 from the supporting member 10 is the same.
The capability for adjustment o~ the sheet metal runners lengthwise is the same and the flexibility of the metal runner 13 to prevent transmission of vibrations impinging on the surfaces of the gypsum wallboards 11 and 12 is the same.

It can readily be appreciated that resilient metal runner 13 may easily be spliced to an adjacent runner, preferably at the connection to a supporting member 10, to provide a continuous metal runner of extended length. Ad~acent metal runners might also be placed in end-to-end abutting relationship against the supporting members 10 to form a continuous row of metal runner sections.
