DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates in general, to envelope type filler insulation with separable clip type fasteners for static structures. The invention more particularly relates to expansible multi-layered reflective foil supported between bays in structures with compressible retaining clips which secure the insulation to the flange of structural beams or members.
BACKGROUND ART
Previously, insulating material in the form of folded flexible metal foil blankets have been installed in building structures using wooden studs, beams or framing members attached with nails, staples, tacks, brads or the like.
Benedict in U.S. Pat. No. 2,101,836 discloses a tack for fastening insulating blankets to framing members with the ends of the blanket folded over for support. U.S. Pat. No. 2,251,585 of Finck likewise utilized tacks to attach a blanket to the studs with a marginal strip added by sewing, pasting etc. Giles, U.S. Pat. No. 2,739,703 employs adhesive, staples or the like to an overlapped section of insulation comprising of kraft paper treated with asphalt and metalized with heat reflective material. Nails are applied as fasteners by Schwartz et al, in U.S. Pat. No. 2,777,786 for fastening purposes. Wiser teaches the use of a tack to the outer panel members of the heat reflective sheet.
Fastening into wood surfaces of prior art is well known however, the need has existed for a simple device for use with metal structural members to attach easily and maintain tension of the insulation blanket between the span.
Joyce in U.S. Pat. No. 2,385,209 takes advantage of a clamp adapted to a beam, however the flange of the member is only engaged by the clamp itself without providing mounting surfaces contiguous with the web.
Williams in U.S. Pat. No. 925,962 issued in Great Britain uses a U-clip for flange mounting however, the flange of the clip, while in intimate contact with the web, lacks sufficient surface area to support insulating blankets. U.S. Pat. No. 3,164,230 of Adams uses a spring clip attached to a T-bar but again only limited surface contact is maintained.
For background purposes and as indicative of the art to which the invention relates reference may be made to the following patents:
No prior art presently provides the combination of attaching reflective insulation blankets with retaining clips to static structural building members.
SUMMARY OF INVENTION
In the past, it has been difficult to effectively insulate metal industrial and agricultural buildings or the like since the roof and wall structure of such buildings do not necessarily utilize construction members to which insulation blankets can be readily attached. Such conventional buildings normally employ I-beam, Z-members or bars or other angle iron beams making it difficult to convenientally attach insulating blankets. More recently the rising costs of energy has made it desirable to insulate such large buildings as it has been shown that by using such insulation on the inside of the roof, up to 30 percent in fuel for heating and cooling these spaces can be saved.
Therefore, a long standing need has been present to provide suitable clips or fasteners which may be readily deployed to secure insulating blankets directly to such bars or beams so that the blankets are readially secured thereto.
The above problems and difficulties are obviated by the present invention in which it is among the primary objects to provide a pair of heat treated spring clips adapted to cooperate with each other in order to hold insulation blankets in place against construction members of different cross sections.
One important object allows the insulation and clips to be easily adapted to variable areas such as walls, floors, subfloors, roofs and ceiling providing a minimum number of configurations for size and space variations.
Another object provides safety provisions as all material is either fireproof, such as the metalic clips and aluminum foil, or flame retardant as in the treated kraft paper allowing safety and applicable building codes to be satisfied. Sti
