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 device and tool include a fitting and a coupler for joining a handle and an end effector such as a broom or mop so that the handle cannot twist with respect to the end effector. The first end of the fitting attaches to the handle. The first end of the coupler threads to the second end of the fitting, and its second end threads to the end effector. Both the fitting and coupler have diametrical passages. A stopper on the coupler will seat in a ramp in the fitting when the coupler and fitting are fully threaded together and the stopper reaches the end wal...

1. A tool, comprising: (a) an end effector with a threaded hole;(b) a handle;(c) a fitting having a first end attached to said handle and an opposing second end having a fitting recess formed therein to define a wall, said wall having interior threads thereon, and said fitting having a first diametrical passage formed through said wall of said second end;(d) a coupler having a first end and a second end opposing said first end of said coupler, said first end of said coupler carrying exterior threads dimensioned for threading said first end of said coupler into said fitting recess of said fitting, said first end of said coupler having a second diametrical passage formed thereacross wherein, when said first end of said coupler is threaded to said second end of said fitting, said first end of said second diametrical passage of said coupler coaxially aligns with the first diametrical passage of the fitting, and wherein said second end of the coupler has exterior threads that thread into said threaded hole of said end effector, said first end of said coupler carrying a stopper thereon, and wherein, when said first end of said stopper is seated in said fitting recess of said second end of said fitting, said first diametrical passage and said second diametrical passage axially align; and(e) a clip having a pin, said pin dimensioned to pass through said first and second diametrical passages. 2. The tool as recited in claim 1, wherein said fitting recess in said second end of said fitting has a ramp formed therein and said ramp has a pitch, and wherein threads of said first end of said coupler have a pitch and wherein said pitch of said ramp and said pitch of said threads of said first end of said coupler are the same. 3. The tool as recite in claim 2, wherein said ramp has an end wall, and wherein, when said stopper engages said end wall of said ramp in said recess of said second end of said fitting, said first end of said coupler is prevented from further forward movement into said recess of said second end of said fitting. 4. The tool as recited in claim 1, further comprising a fastener, said fastener fastening said first end of said fitting to said handle. 5. The tool as recited in claim 1, further comprising a post oriented axially inside said fitting recess of said second end of said fitting, said post having a transverse hole formed therein and aligned with said first diametrical passage of said second end of said fitting so as to coincide with said first diametrical passage. 6. The tool as recited in claim 1, wherein said first end of said coupler has a coupler recess formed therein, said coupler recess defining an axial wall, said axial wall carrying said exterior threads. 7. The tool as recited in claim 6, wherein axial wall has a rim and wherein said stopper is carried by said rim of said axial wall. 8. The tool as recited in claim 1, wherein said second end of said fitting has a post oriented axially inside said fitting recess of said second end, said post having a transverse hole formed therein and aligned with said first diametrical passage of said second end of said fitting so as to continue said first diametrical passage, and wherein said first end of said coupler has a coupler recess formed therein, said coupler recess defining an axial wall, said axial wall carrying said exterior threads of said first end of said coupler, said post of said second end of said fitting being dimensioned to be receivable in said coupler recess. 9. The tool as recited in claim 1, wherein said clip further comprises opposing arms. 10. A device, comprising: (a) a handle having fitting recess formed therein, said recess defining a wall, said wall having interior threads and a first diametrical passage formed across said second end of said handle, through said wall and across said fitting recess; and(b) a coupler having a first end and a second end opposing said first end of said coupler, said first end of said coupler carrying exterior threads dimensioned for threading into said fitting recess in said second end of said handle, said first end of said coupler having a second diametrical passage formed thereacross, wherein, when said first end of said coupler is threaded to said second end of handle, said second diametrical passage of said coupler coaxially aligns with said first diametrical passage of said second end of said handle, said first end of said coupler carrying a stopper on said first end of said coupler, and wherein when said stopper seats in said recess of said second end of said handle, said first and said second diametrical passages are axially aligned. 11. The device of claim 10, wherein said fitting recess of said handle has a ramp formed therein, and wherein, when said first end of said coupler is threaded to said second end of said handle, said first and said second diametrical passages axially align when said stopper seats in said ramp. 12. The device of claim 10, further comprising an end effector, said end effector being attached to said second end of said coupler. 13. The device of claim 12, wherein said end effector has a recess with interior threads formed therein and said second end of said coupler carries exterior threads so that said exterior threads of said second end of said coupler thread to said interior threads of said recess of said end effector. 14. The device of claim 12, wherein said end effector is a broom. 15. The device of claim 12, wherein said end effector is a mop. 16. The device as recited in claim 10, further comprising a clip having a pin and opposing arms, said pin being dimensioned to pass through said first and second diametrical passages wherein said clip further comprises opposing arms, said arms gripping said second end of said handle when said pin of said clip is inserted into said first and second diametrical passages. 17. A device, comprising: (a) a fitting having a first end and a second end opposing said first end, said second end having a fitting recess formed therein, said fitting recess defining a wall, said wall having interior threads, and said fitting having a first diametrical passage formed across said second end, said fitting recess having a ramp formed therein; and(b) a coupler having a first end and a second end opposing said first end, said first end of said coupler carrying exterior threads and being dimensioned to be received in said second end of said fitting, said first end of said coupler having a second diametrical passage formed thereacross, said first end of said coupler carrying a stopper, and wherein, when said stopper of said first end of said coupler seats in said ramp of said second end of fitting, said second diametrical passage of said coupler coaxially aligns with first diametrical passage of said fitting. 18. The device of claim 17, further comprising a clip having a pin and opposing arms, said pin dimensioned to pass through said first and second diametrical passages and said opposing arms grip said fitting when said first and second diametrical passages are axially aligned. 19. The device of claim 17, wherein said ramp has a pitch and wherein threads of said first end of said coupler have a pitch and wherein said pitch of said ramp and said pitch of said threads of said first end of said coupler are the same. 20. The device of claim 17, wherein said ramp has an end wall and wherein said stopper is seated in said ramp when said stopper reaches said end wall. 21. The device of claim 17, wherein said first end of said coupler has a rim and wherein said stopper is carried by said rim of first end of said coupler.
