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 auxiliary handle for use on an elongated rod-shaped handle of a tool includes an open loop member with a pair of opposed clamping arms connected to each other solely at a first end thereof via a gripping portion. The clamping arms have free distal end portions defining therebetween an opening adapted to receive the elongated rod-shaped handle. The clamping arms are displaceable about the gripping portion between a first position for accommodating rod-shaped handles of different cross-sectional dimensions and a second position wherein the clamping arms are resiliently depressed one towards the other for clamping onto the rod-shaped handle of the tool. The auxiliary handle also includes an actuator adapted to be connected to the clamping arms for controlling their movement between the first and second positions.

What is claimed is: 1. An auxiliary handle for use on an elongated rod-shaped handle of a tool, comprising an open loop member comprising a pair of opposed clamping arms connected to each other solely at a first end thereof via a gripping portion and having free distal end portions defining therebetween an opening adapted to receive said elongated rod-shaped handle, the free distal end portions having locking portions, a first one of the locking portions including a hole therein and a second one of the locking portions including a slot extending from the bottom edge thereof, said clamping arms being displaceable about said gripping portion between a first position for accommodating rod-shaped handles of different cross-sectional dimensions and a second position wherein said clamping arms are resiliently depressed one towards the other for clamping onto said rod-shaped handle of said tool, and an actuator extending transversally through the hole and the slot of the locking portions for controlling the movement thereof between said first and second positions. 2. Auxiliary handle according to claim 1, wherein said gripping portion and said opposed clamping arms are integral. 3. Auxiliary handle according to claim 1, wherein said actuator comprises a threaded fastener extending transversally through said locking portions. 4. Auxiliary handle according to claim 3, wherein said threaded fastener comprises a knob handle and a threaded bolt, wherein said threaded bolt comprises a threaded shank and an elongated head extending at right angles from one end of said threaded shank, said elongated head being received in a complementary elongated slot defined in one of said locking portions. 5. Auxiliary handle according to claim 3, wherein said first one of said locking portions comprises an elongated cavity adapted to receive an elongated head of said threaded fastener while a threaded shank thereof transversally extends through said locking portions, wherein said elongated head prevents rotation of said threaded fastener relative to said locking portions once said threaded fastener is properly positioned in said hole and said slot and said elongated head is properly positioned in said elongated cavity. 6. Auxiliary handle according to claim 1, wherein said locking portions diverge from one another. 7. Auxiliary handle according to claim 1, wherein said actuator comprises a rod. 8. An auxiliary handle adapted to be releasably mounted to elongated-rod shaped handles of different dimensions, comprising a grip, a pair of clamping arms extending from opposed ends of said grip, said clamping arms having spaced-apart distal end portions defining a seat therebetween for receiving a rod-shaped handle of a tool, said distal end portions terminating below said seat into outwardly angled fingers diverging from one another, and a threaded fastener extending transversally through said outwardly angled fingers for selectively causing said clamping arms to be moved towards a closed position in order to releasably clamp the auxiliary handle to the rod-like shaped handle. 9. An auxiliary handle as claimed in claim 8, wherein a first one of said outwardly angled fingers comprise a hole therein and a second one of said outwardly angled fingers comprises a slot extending from the bottom edge thereof to allow said threaded fastener to extend transversally through said outwardly angled fingers. 10. An auxiliary handle as claimed in claim 9, wherein said threaded fastener includes a bolt having a head at a first end and a knob threadably engaged on a second end of the bolt, opposite to the first end, the knob extending outwardly of said second one of said outwardly angled fingers. 11. The auxiliary handle defined in claim 10, wherein the head of the bolt has an elongated shape, and wherein the head is received in a complementary elongated slot defined in the first one of said outwardly angled fingers. 12. An auxiliary handle for use on an elongated rod-shaped handle of a tool, comprising a grip, a pair of clamping arms extending from opposed sides of the grip and having opposed free distal end portions diverging from one another, a threaded fastener extending transversally through said free distal end portions for displacing said clamping arms between an unlocking position and a locking position, and wherein said threaded fastener extends through a hole defined in a first one of said free distal end portions and through a slot defined in a second one of said distal end portions, said slot extending in a longitudinal direction of said clamping arms to permit tilting of said threaded fastener. 13. The auxiliary handle defined in claim 12, wherein the slot has an open bottom end for allowing the threaded fastener to be pivoted out of engagement from said second one of said distal end portions. 14. The auxiliary handle defined in claim 13, wherein said threaded fastener includes a bolt having a head at a first end and a knob threadably engaged on a second end of the bolt, opposite to the first end, the knob extending outwardly of said second one of said distal end portions. 15. The auxiliary handle defined in claim 14, wherein the head of the bolt has an elongated shape, and wherein the head is received in a complementary elongated slot defined in the first one of said distal end portions. 16. An auxiliary handle for use on an elongated rod-shaped handle of a tool, comprising a grip, a pair of clamping arms extending from opposed sides of the grip, said clamping arms converging towards one another from the grip and defining a seat therebetween with a variable diameter for receiving a rod-shaped handle of a tool, said clamping arms terminating below said seat into free end locking portions, a threaded fastener extending transversally through said locking portions for displacing said clamping arms between an unlocking position and a locking position, and wherein said threaded fastener extends through a hole defined in a first one of said free end locking portions and through a slot defined in a second one of said free end locking portions, said slot extending in a longitudinal direction of said clamping arms to permit tilting of said threaded fastener. 17. An auxiliary handle as claimed in claim 16, wherein the free end locking portions diverge from one another. 18. An auxiliary handle as claimed in claim 16, wherein said threaded fastener comprises a knob handle and a threaded bolt, said threaded bolt including a threaded shank and an elongated head extending at right angles from one end of said threaded shank, said elongated head being received in a complementary elongated slot defined in one of said locking portions.
