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.

An air baffle structure for refrigerated display cases having an open front and provided with openings at the back for the forwardly directed flow of refrigerated air. The display case has a display bar of non-circular cross section for mounting a plurality of display trays. A baffle support, formed of wire and having a front portion and spaced apart side portions, is mounted on the display bar and extends closely underneath the trays. A flat, plastic baffle plate is carried by the baffle support. The baffle support has rear portions of inverted U-shape engaging the display bar, formed in part by upwardly extending baffle positioning elements. Back edge portions of the baffle plate releasably engage the positioning elements to secure the baffle plate in position while accommodating easy removable and replacement for cleaning. A baffle plate typically will extend under a plurality of display trays positioned on the display bar.

1. An air baffle structure for an open front refrigerated display case, where the display case is provided with a back wall with openings for the forward flow of refrigerated air and where a display bar of non-circular cross section extends horizontally in front of said back wall, which comprises, (a) one of more product display trays mounted in cantilever fashion at back ends thereof on said display bar and extending forwardly from said display bar for the display of merchandise in said display case,(b) a baffle support mounted on said display bar and extending generally horizontally forwardly therefrom,(c) said baffle support including laterally spaced apart support elements extending horizontally outward with respect to said display bar and upwardly extending portions joined with inner end portions of said support elements,(d) said upwardly extending portions being secured to and positioned adjacent to said display bar, and(e) a thin, generally flat baffle plate removably supported on said baffle support,(f) said baffle support and said baffle plate extending underneath said one or more trays in closely spaced relation to bottoms thereof,(g) said baffle plate having positioning elements at a rear edge region thereof engaging said upwardly extending portions for releasably positioning said baffle plate with respect to said baffle support. 2. The air baffle structure of claim 1, wherein (a) said positioning elements are spaced apart slots in said rear edge region of the baffle plate for the reception of said upwardly extending portions. 3. The air baffle structure of claim 2, wherein (a) said spaced apart slots are narrower in width than a width of said upwardly extending portions, and(b) said positioning elements include enlarged portions at forward ends of said slots, and(c) said enlarged portions receive said upwardly extending portions when said baffle plate is properly positioned on said baffle support. 4. The air baffle structure of claim 1, wherein (a) rear edge regions of said baffle plate extend behind said upwardly extending portions of said baffle support, toward said back wall. 5. The air baffle structure of claim 1, wherein (a) said baffle support includes a pair of mounting portions of generally inverted U-shaped configuration for reception over said display bar,(b) said mounting portions each comprise front and back generally vertically extending portions connected at upper ends thereof by a generally horizontally extending portion, and(c) one of said generally vertically extending portions extends from one of the upwardly extending portions at each side of said baffle support. 6. The air baffle structure of claim 5, wherein (a) the spaced apart support elements of said baffle support, and said upwardly extending portions thereof, are formed of a continuous section of wire. 7. The air baffle structure of claim 1, wherein (a) said baffle plate has a width dimension such, in relation to a width dimension of said display trays, as to be able to underlie a plurality of display trays. 8. The air baffle structure of claim 1, wherein (a) the baffle support includes a cross member connecting the respective support elements in spaced apart relation. 9. The air baffle structure of claim 8, wherein (a) the cross member is integrally joined with outer ends of the respective support elements. 10. An air baffle structure for an open front refrigerated display case, where the display case is provided with a back wall with openings for the forward flow of refrigerated air and where means are provided for supporting in said display case a plurality of product display trays arranged in vertically spaced horizontal rows with each row comprising a plurality of product display trays, said baffle structure comprising (a) a plurality of vertically spaced display bars extending laterally across at least a portion of the width of said refrigerated display case,(b) said plurality of product display trays being mounted in cantilever fashion and in side-by-side relation on said display bars,(c) baffle supports mounted at inner ends thereof in cantilever fashion on said display bars and extending outwardly relative to said back wall closely underneath one or more of said product display trays mounted on the same display bar,(d) said baffle supports each including a laterally spaced apart pair of baffle support elements extending outwardly with respect to said back wall,(e) a thin, generally flat baffle plate removably supported on each pair of said spaced apart baffle support elements closely adjacent to but spaced below bottoms of said display trays,(f) at least one of said baffle support elements of each pair having an associated upwardly projecting baffle plate positioning element releasably engageable with a positioning element on said baffle plate for releasably securing said baffle plate in a predetermined working position on said baffle support. 11. The air baffle structure of claim 10, wherein (a) said baffle support elements each have an upwardly projecting baffle plate positioning element adjacent to a back end thereof, and(b) said baffle plates each have a pair of laterally spaced apart rearwardly opening slots therein releasably engageable with said upwardly projecting baffle plate positioning elements for positioning said baffle plate. 12. The air baffle structure of claim 10, wherein (a) said baffle plates are of sufficient width to extend underneath at least two of said product display trays. 13. The air baffle structure of claim 10, wherein (a) each of said baffle support elements has an associated baffle plate positioning element and each of said baffle plates has a pair of positioning elements for releasable engagement with said baffle plate positioning elements,(b) said positioning elements on said baffle plates comprise rearwardly opening slots of a width narrower than a width of said baffle plate positioning elements, and(c) openings of greater width than said slots are connected to forward ends of said slots for receiving said baffle plate positioning elements. 14. The air baffle structure of claim 10, wherein (a) said baffle plate is of generally rectangular configuration having spaced apart lateral edges and a front edge,(b) said baffle support is of a rearwardly opening, generally U-shaped configuration including laterally spaced apart elements extending outwardly and a laterally extending element connecting outer end portions of said laterally spaced apart elements, and(c) said laterally spaced apart elements and said laterally extending element of said baffle support being spaced inward from said lateral and front edges of said baffle plate.
