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 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.

1. A litter box assembly comprised of: a base tray having a bottom wall, opposing side walls, a back wall and a front wall, said front wall having a height less than said opposing side walls to define a partially open end of said base tray and an upper edge of each of said opposing side walls formed to define a flange; andan insert dimensioned to be disposed within said base tray, said insert having a bottom wall, opposing side walls and a back wall, said bottom wall having a plurality of openings formed in a portion thereof and a leading edge that extends between ends of said opposing side walls wherein said leading edge of said bottom wall and said ends of said opposing side walls define an open end of said insert, each of said opposing side walls of said insert formed to define a mating flange, each of said mating flanges formed to define an opening at said end of said opposing side wall,wherein said insert is insertable into said base tray through said partially open end of said base tray such that when said leading edge of said insert is disposed adjacent to said front wall of said base tray, said opening of each of said mating flanges of said insert receives one of said flanges of said base tray, and wherein said leading edge of said insert engages and slides along said bottom wall of said base tray and each of said mating flanges of said insert engages and slides along one of said flanges of said base tray to guide said insert into said base tray as said insert is inserted into said base tray. 2. A litter box assembly as defined in claim 1, wherein said flange of said base tray and said mating flange of said insert are J-shaped. 3. A litter box assembly as defined in claim 1, wherein said plurality of openings of said insert define a screen portion of said bottom of said insert. 4. A litter box assembly as defined in claim 1, wherein an angle between said bottom of said insert and said bottom of said base tray when said leading edge of said insert engages said bottom wall of said base tray near said front wall of said base tray is between about 60 degrees and about 30 degrees. 5. A litter box assembly as defined in claim 1, wherein said mating flange of said insert extends along a top of said side walls and a top of said back wall of said insert. 6. A litter box assembly as defined in claim 4, wherein said angle is between about 50 degrees and about 40 degrees. 7. A litter box assembly as defined in claim 6, wherein said angle is about 45 degrees. 8. A litter box assembly comprised of: a base tray having a bottom wall, opposing side walls, a back wall and a front wall, said front wall having a height that is less than about 50% of the height of said opposing side walls to define a partially open end of said base tray and an upper edge of each of said opposing side walls formed to define a flange; andan insert dimensioned to be disposed within said base tray, said insert having a bottom wall, opposing side walls and a back wall, said bottom wall having a plurality of openings formed in a portion thereof and a leading edge that extends between ends of said opposing side walls wherein said leading edge of said bottom wall and said ends of said opposing side walls define an open end of said insert, each of said opposing side walls of said insert formed to define a mating flange, each of said mating flanges formed to define an opening at said end of said opposing side wall,wherein said insert is insertable into said base tray through said partially open end of said base tray such that when said leading edge of said insert is disposed adjacent to said front wall of said based tray, said opening of each of said mating flanges of said insert receives one of said flanges of said base tray, and wherein said insert engages and slides along said bottom wall of said base tray and each of said mating flanges of said insert engages and slides along one of said flanges of said base tray to guide said insert into said base tray as said insert is inserted into said base tray. 9. A litter box assembly as defined in claim 8, wherein said front wall has a height that is between about 25% and about 45% of the height of said opposing side walls. 10. A litter box assembly as defined in claim 9, wherein said front wall has a height that is about 25% of the height of said opposing side walls. 11. A litter box assembly comprised of: a base tray having a bottom wall, opposing side walls, a back wall and a front wall, said front wall having a height less than said opposing side walls to define a partially open end of said base tray; andan insert dimensioned to be disposed within said base tray, said insert having a bottom wall, opposing side walls and a back wall,said bottom wall having a plurality of openings formed in a portion thereof and a leading edge that extends between ends of said opposing side wallswherein said leading edge of said bottom wall and said ends of said opposing side walls define an open end of said insert and an upper edge of each of said opposing side walls formed to define a flange near said ends of said opposing side walls,wherein said insert is insertable into said base tray through said partially open end of said base tray such that said leading edge of said insert engages and slides along said bottom wall of said base tray andeach of said flanges on said opposing side walls of said insert engages an upper edge of one of said opposing side walls of said base tray as said insert is inserted into said base tray andwherein said back wall of said insert has a height equal to said opposing side walls of said base tray such that said back wall of said insert is disposed next to said front wall of said base tray andsaid back wall of said insert closes said partially open end of said base tray when said insert is disposed in said base tray.
