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.

What is claimed is: 1. A supermarket trolley comprising a base made of moulded plastic material with wheels and two lateral uprights integral with the base and connected superiorly by a transverse bar and a basket container also made of moulded plastic material, connected at an end to said two lateral uprights, wherein said two lateral uprights of the base and said ends of the basket have respective mutually facing surfaces formed with substantially comb like formations mutually complementary and meshed following a relative coupling motion between said basket and said base along a direction of coupling when the trolley is assembled, and wherein said direction of coupling is substantially parallel to said uprights. 2. A trolley as claimed in claim 1, wherein said two lateral uprights and said end of the basket are formed with tongue and groove elements designed to engage each other as a result of the meshing between said comb like formations. 3. A trolley as claimed in claim 2, wherein said tongue and groove elements include, for each upright, a pair of respectively upper and lower seats designed to house a pair of corresponding upper and respectively lower projections of the basket. 4. A trolley as claimed in claim 1, wherein said comb like formations comprise a plurality of parallel projections generally elongated in said direction of coupling. 5. A trolley as claimed in claim 4, wherein said elongated projections are slightly inclined relative to said direction of coupling. 6. A trolley as claimed in claim 1, wherein said base and said basket are capable of being mutually locked relative to said direction of coupling by means of said transverse bar. 7. A trolley as claimed in claim 1, wherein said basket is open in correspondence with said end. 8. A trolley as claimed in claim 7, further including a child seat assembly applied in correspondence with said open end of the basket by means of said transverse bar. 9. A trolley as claimed in claim 1, wherein said base has a double "L" configuration whose vertical branches constitute said uprights and whose horizontal branches are interconnected by a front transverse member (5) and support a bearing plane. 10. A trolley as claimed in claim 1, wherein said end of the basket includes a pair of elongated elements with respective legs projecting underneath the basket. 11. A supermarket trolley comprising a base made of moulded plastic material with wheels and a support formed integral with the base and including two lateral uprights connected superiorly by a transverse bar and a basket container also made of moulded plastic material, connected at an end to said two lateral uprights, wherein said two lateral uprights of the base and said ends of the basket have respective mutually facing surfaces formed with substantially comb like formations mutually complementary and meshed following a relative coupling motion between said basket and said base along a direction of coupling when the trolley is assembled, wherein said direction of coupling is substantially parallel to said uprights. 12. A trolley as claimed in claim 11, wherein said two lateral uprights and said end of the basket are formed with tongue and groove elements designed to engage each other as a result of the meshing between said comb like formations. 13. A trolley as claimed in claim 11, wherein said tongue and groove elements include, for each upright, a pair of respectively upper and lower seats designed to house a pair of corresponding upper and respectively lower projections of the basket. 14. A trolley as claimed in claim 11, wherein said comb like formations comprise a plurality of parallel projections generally elongated in said direction of coupling. 15. A trolley as claimed in claim 11, wherein said elongated projections are slightly inclined relative to said direction of coupling. 16. A trolley as claimed in claim 11, wherein said base and said basket are capable of being mutually locked relative to said direction of coupling by means of said transverse bar. 17. A trolley as claimed in claim 11, wherein said basket is open in correspondence with said end. 18. A trolley as claimed in claim 11, further including a child seat assembly applied in correspondence with said open end of the basket by means of said transverse bar. 19. A trolley as claimed in claim 11, wherein said base has a double "L" configuration whose vertical branches constitute said uprights and whose horizontal branches are interconnected by a front transverse member (5) and support a bearing plane. 20. A trolley as claimed in claim 11, wherein said end of the basket includes a pair of elongated elements with respective legs projecting underneath the basket. 21. A supermarket trolley comprising a base made of moulded plastic material with wheels and two lateral uprights integral with the base and connected superiorly by a transverse bar and a basket container also made of moulded plastic material, connected at an end to said two lateral uprights, wherein said two lateral uprights of the base and said ends of the basket have respective mutually facing surfaces formed with substantially comb like formations mutually complementary and meshed following a relative coupling motion between said basket and said base along a direction of coupling when the trolley is assembled, and wherein said direction of coupling is substantially parallel to said uprights, wherein said two lateral uprights and said end of the basket are formed with tongue and groove elements designed to engage each other as a result of the meshing between said comb like formations, and wherein said tongue and groove elements include, for each upright, a pair of respectively upper and lower seats designed to house a pair of corresponding upper and respectively lower projections of the basket.
