연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A portable fire resistant case 10 is made with a molded, double-walled resin body 11 and cover 12 hinged and locked together and filled with insulation in the spaces between the double walls. Spring latches 30 mounted on body 11 engage interlock surfaces 33 on cover 12 to hold cover 12 to body 11 independently of the hinge and are assisted in this by a lock element 27 engaging and holding projections on the inside of body 11. Body 11 and cover 12 are formed with molded filling projections 19 and 20 forming passageways into cavities 11c and 12c that are filled with insulation through filling projections 19 and 20. Projections 19 and 20 and overfilled insulation material that they contain are cut away after the insulation has set to leave insulation stubs 23 and 24 over which escutcheons 25 and 26 are mounted on the lock side of case 10.

1. A system of making a case fire resistant, said system comprising: a. molded resin forms having double walls defining cavities respectively shaped to form a body and cover for said case; b. filling projections formed in said walls of said forms to communicate with said cavities; c. said cavities being filled with fire resistant insulation material cast in said forms to enclose the interior of said case and partially fill said filling projections; d. said filling projections being cut away to leave exposed insulation bounded by said resin walls; and e. resin material covering said exposed insulation for sealing and concealing said insulation material. 2. The system of claim 1 wherein said filling projections are formed in outer walls of said forms and cut away to leave stubs projecting from said outer walls, and said resin material covering said stubs is formed as molded resin escutcheons. 3. The system of claim 2 wherein said stubs for said body and cover are adjacent each other when said cover is closed against said body. 4. The system of claim 2 wherein said stubs have through bores and said escutcheons have pins extending through said bores and secured on the interior of said case. 5. The system of claim 4 including a lock mounted on one of said escutcheons, internally projecting pins on said body and said cover, and said lock being arranged to engage said pins for holding said cover closed against said body. 6. In a case having a body and a cover that can be held releasably closed together, an improvement making said case fire resistant, said improvement comprising: a. molded resin forms having double walls defining cavities respectively shaped to form said body and said cover and having filling openings communicating with said cavities; b. fire resistant insulation material filling said cavities in said body and cover and extending into said filling openings; c. severed stubs of said insulation material remaining in said filling openings; and d. resin material covering and sealing said severed stubs. 7. The improvement of claim 6 wherein said severed stubs extend outward from outer walls of said body and cover, and said resin material covering and sealing said severed stubs is formed as molded resin escutcheons. 8. The improvement of claim 7 wherein said stubs have through bores and said escutcheons have pins extending through said bores and secured on the interior of said case. 9. The improvement of claim 7 including a lock mounted on one of said escutcheons, lock pins respectively mounted on the interior of said body and said cover, and said lock engaging said lock pins for holding said cover closed against said body. 10. The improvement of claim 6 wherein said severed stubs are adjacent each other when said cover is closed against said body. 11. A method of making a case fire resistant, said case having a body and cover that can be held releasably closed together, said method comprising: a. molding forms for said body and cover of resin material having double walls defining cavities in the shapes of said body and cover and having filling projections communicating with said cavities; b. flowing fire resistant insulation material through said filling projections and into said cavities to fill said cavities and portions of said filling projections; c. after said insulation material is set, cutting off said filling projections and said insulation material in said filling projections to leave severed stubs of exposed insulation bounded by said forms; and d. securing resin material over said severed stubs for covering and sealing said insulation material. 12. The method of claim 11 including hingedly connecting said body and cover before filling said cavities with said insulation material, and disposing said body and cover filling projections adjacent each other when said cover is closed against said body. 13. The method of claim 11 including boring holes through said severed stubs and forming said covering resin material as molded escutcheons having pins that extend through said holes and are secured on the inside of said body and cover. 14. The method of claim 11 including forming lock pins on the interior of said body and cover and mounting a lock to engage said lock pins for holding said cover closed against said body. 15. The method of claim 11 including blow molding said resin forms for said body and cover and cutting away resin material from outer ends of said filling projections to open passageways extending through said filling projections to said cavities.
