INVENTORS United States Patent 2,999,278 INSULATION MOUNTING William H. Spencer, La Canada, and James D. Brown, Los Angeles, Calif., assignors to Ultra-tTach Co., Los Angeles, 'Calif., a partnership Continuation of application Ser. No. $31,220, Aug. 29, 1955. This application Jan. 21, 1959, Ser. No. 788,235 9 Claims. (Cl. 20-4) The present invention relates generally to insulation mounting and particularly to an easily positioned insulation mounting requiring no special tools or implements for its installation. More specifically the invention relates to a mounting designed for the retention of sound and heat absorbing insulation adjacent a surface, particularly a roof surface, and which is particularly adapted to be mounted between wall and roof supporting purlins varying in spacing.

Sound and heat insulation materials are commercially available in granular, solid and fiber forms and are conventionally positioned against or relatively close to a wall or roof surface. A common and well-known place of use is upon the underside of a roof or decking where it is able to perform a double function, first preventing the passage of exterior heat into the enclosure and secondly preventing the reflection of sound waves traveling within the interior of the enclosure. A roof or deck may be a flat wooden element or it may be a corrugated sheet metal member, supported, in either instance, by spaced purlins, joists, or beams. The insulation in continuous strips may run between and parallel to the supporting purlins, and may either contact or be spaced slightly from the inner surface of the roof or deck. Where the roof or deck is of metal the supporting function is preferably accomplished, according to the present invention, by manually positioned br-acket elements engaged at their opposite ends with the purlins. The purlins may vary in spacing and accordingly it is desirable that the brackets be longitudinally adjustable as to adapt themselves to this variation.

The present invention comprises an improvement upon the construct-ion disclosed and claimed in co-pending application of applicants identified as Serial No. 367,932, entitled Insulation Mounting and now abandoned. The present application is a continuation of our co-pending application for United States Letters Patent Serial No. 531,220, filed August 29, 1955, for Insulation Mounting and now abandoned.

Referring now to the drawing in which preferred embodiments of the present invention are illustrated:

FIGURE 1 is a partial section through a roof illustrat ing insulation supported below the roofing by a bracket member constructed in accordance with the present invention;

FIGURE 2 is a view looking in the direction of the arrows upon the line 22 of FIGURE 1;

FIGURE 3 is a transverse section through the bracket upon the line 3-3 of FIGURE 1;

FIGURE 4 is a view in perspective of the bracket alone; and

FIGURE 5 is a view similar to FIGURE 4 showing a bracket constructed in accordance with a second preferred embodiment of the invention.

Referring again to the drawing, and to FIGURES 1 to 4, inclusive, in particular, the first preferred embodiment of the invention is illustrated. A section of roof is indicated generally by the reference character and is seen to comprise a corrugated sheet roofing 10.1 supported by spaced longitudinally extending U-sectioned purlins 11 extending transversely of the corrugations of the roofing. The downwardly convex or valley portions of the roofing 10.1 rest directly upon the purlins although the relation- Patented Sept. 12, 1961 ship is such that there is frequently space therebetween, either present or readily obtainable by the exertion of a slight lifting force on the roofing. The upwardly convex portions of the roofing are, as is most readily seen in FIGURE 2, spaced from the upper flange 11.1 of the purlins. The insulation, indicated by the reference character 12, extends between the purlins 11. Its length depends upon the run to be covered and it is to be understood that a single continuous length or a plurality of abutting lengths of insulation 12 may be used. Insulation 12 may be of any common and well-known type and it has been found that ran ultra-light bracket-type insulation such as fiberglass batting is entirely suitable although, it is to be understood, the invention is not limited to a particular type of insulation. It would be possible to make use of insulation batting of material other than fiberglass, and it is within the scope of the invention that the insulation 12 should be relatively inflexible solid members rather than flexible batting.

The insulation 12 must be retained in position below the roofing 10.1 and to accomplish this result there are provided brackets, indicated generally by the reference character 15, positioned at spaced intervals along the length of the insulation 12 and extended between the purlins 11. The exact spacing of the brackets 15 is not of the essence and will depend in part upon the flexibility of the insulation 12 determining the requirement for support to prevent sagging. Bracket 15 is seen to comprise an elongated central run 16 which is generally V-shaped in section, as illustrated in FIGURE 3, with inturned overhanging flanges 16.1 at the outer sides of the V. End members 17 are positioned at the opposite ends of the central run 16 and include longitudinal extensions or runs 17 .1 sectioned similarly to the central run 16, except for the inturned flanges 16.1, and adapted to seat therein as illustrated in FIGURE 3. End members 17 also have right-angled transverse runs 17.2 which terminate in flanges 17.3 which extend parallel to the longitudinal extensions 17 .1 and to the central run 16. As is seen most clearly in FIGURE 4, the longitudinal runs or extensions 17.1 seat slidably in central run 16 and have a length which enables each member 17 to he adjusted longitudinally relative to central run 16 within a range of about six to ten inches. The flanges 17.3 of the members 17 extend in the same direction which means that with respect to the central run 16 one flange 17.3 is turned outwardly While at the opposite end its counterpart is turned inwardly. This is seen most clearly in FIGURE 4. A second and overlying flange 17.5 is carried by the short run 17.4 and extends parallel to and adjacent the inturned flange 17.3, the two flanges 17.3 and 17.5 forming a U of a size adapted to receive and seat the top flange 11.1

of a purlin in the manner illustrated clearly in FIGURE 1.

while the smaller upper portion of the S frictionally' embraces flange 11.1 of purlin 11. The outer flange 17.5

is spaced the same distance from the plane of the central run 16 as is the flange 17.3 at the opposite end which means, of course, that both ends of the bracket are spaced the same distance from the purlin.

The mounting of the insulation and the supporting bracket constructed in accordance with this first embodiment of the invention is simple. Insulation 12 is held flat against the underside of the roof 10 and the right hand end of the bracket 15, as viewed in FIGURES 1 and 4, is positioned by seating the purlin upper flange 11.1 in the U seat formed between the horizontal flanges 17.3 and 17.5. The opposite end of the bracket unit is then adjusted relative to the seated end by sliding the longitudinal runs 17 .1 relative to the central run 16 until the proper length is obtained and the flange 17.3 overlies the adjacent purlin top flange 11.1 in the manner illustrated in FIGURE 1. As the runs 17.1 of the end members 17 seat slidably but frictionally within the central runs 16 when once positioned they retain their longitudinal adjustment in the absence. of a positive adjusting force. With the bracket so positioned the batting 1 2 is supported by the central run 16 and the longitudinal run'17.1. Successive brackets 15 are then positioned along the length of the insulation at spaced intervals as required, the positioning operation being identical in each instance.

Referring now to FIGURE in particular, a second preferred embodiment of the invention is illustrated. This form is to be understood as being identical to the first described embodiment except as specified. In this embodiment a bracket is a two-piece unit rather than a three-piece as in the first embodiment. The left-hand end member 17 is identical to that of the first described embodiment with the exception that the longitudinal run 17.1 is extended and has a length which is somewhat greater than half the length of the bracket when fully expanded. The right-hand member 17 is also identical to the right-hand end member of the first embodiment with the exception that longitudinal run 17.1 of the first embodiment has been replaced by a longitudinal run 171A having a section identical to that of the central run 16 of the first embodiment. Stated differently, the right-hand end member 17 now embodies the central run 16 of the first embodiment as an integral part as its longitudinal run 17.1A. The elongated run 17.1A is V-sectioned like the run'16 of the first embodiment and has inturned upper flanges indicated at 17.113. Additionally, the male run 17.1 is frictionally slidable Within the female member 1713 so that the two parts remain in an adjusted longitudinal position after having been once so positioned.

The positioning and adjustment of this second embodiment of the invention is similar to that first described with the exception that the entire movement and the longitudinal adjustment takes place between the two longitudinal runs 17.1 and 17.1A rather than between the three parts 17.1, 16 and 17.1 as in the first embodiment.

While the particular apparatus here shown and disclosed in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred embodiments of the invention and that no limita tions are intended to the details of construction or design herein shown other than as defined in the appended claims.
