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.

A ball handle assembly for a handheld tool is provided. The handheld tool includes a powered mechanism, an actuating mechanism for actuating the powered mechanism, and an elongated boom extending between the powered mechanism and the actuating mechanism. A ball handle assembly is adjustably attached to the boom to allow a user to adjust the ball handle assembly relative to the boom to provide a comfortable and ergonomic orientation regardless of the handedness of the operator. The ball handle assembly is translatable along the length of the boom, and the...

1. A ball handle assembly for a handheld tool-having a powered mechanism, said ball handle assembly comprising: a boom;a ball selectively securable directly to said boom, wherein movement of said ball relative to said boom is prevented when said ball is secured to said boom;a grip assembly operatively connected to said ball; anda clamping mechanism attached to said grip assembly, wherein a portion of said clamping mechanism is selectively actuatable between a secured position and an unsecured position for selectively securing said ball to said boom;wherein said grip assembly has three degrees of rotation relative to said ball when said clamping mechanism is in said unsecured position;wherein said grip assembly includes a first cup member integrally formed with a grip and a second cup member attachable to said first cup member for securing said ball therebetween;wherein both of said first and second cup members includes a hook and an anchor spaced apart from said hook by way of a gap, and said clamping mechanism is rotatably attached to said anchors and releasably engageable to said hooks for selective actuation between said secured position and said unsecured position. 2. The ball handle assembly of claim 1, wherein when said clamping mechanism is in said secured position, said clamping mechanism is engaged with said hooks which generates a compression force on said ball and when said clamping mechanism is in said unsecured position, said clamping mechanism is disengaged from said hooks. 3. The ball handle assembly of claim 1, wherein said ball and grip assembly are selectively positionable along a length of said boom. 4. The ball handle assembly of claim 1, wherein said grip assembly has three degrees of rotation relative to said ball: i. rolling about a longitudinal axis of said boom;ii. pitching about an axis of rotation that is horizontally perpendicular to said longitudinal axis of said boom; andiii. yawing about an axis of rotation that is vertically perpendicular to said longitudinal axis of said boom. 5. The ball handle assembly of claim 4, wherein said grip assembly is rollable between zero degrees and three hundred sixty degrees)(360°) relative to said longitudinal axis of said boom, said grip assembly is pitchable between about thirty degrees)(30°) in a forward direction and about thirty degrees)(30°)in a rearward direction relative to said longitudinal axis of said boom, and said grip assembly is yawable between about thirty degrees) (30°) in a forward direction and about thirty degrees)(30°) in a rearward direction relative to said longitudinal axis of said boom. 6. A ball handle assembly for a handheld tool-having a powered mechanism, said ball handle assembly comprising: a boom;a ball selectively securable directly to said boom, wherein movement of said ball relative to said boom is prevented when said ball is secured to said boom;a grip assembly operatively connected to said ball; anda clamping mechanism attached to said grip assembly, wherein a portion of said clamping mechanism is selectively actuatable between a secured position and an unsecured position for selectively securing said ball to said boom;wherein said grip assembly has three degrees of rotation relative to said ball when said clamping mechanism is in said unsecured position;wherein said ball is formed of two halves that are operatively connectable to each other. 7. The ball handle assembly of claim 6, wherein each of said halves of said ball includes an upper mating surface, a lower mating surface, a channel extending between said upper and lower mating surfaces, a protrusion extending from said upper mating surface, and a detent formed into said lower mating surface. 8. The ball handle assembly of claim 7, wherein said protrusion of each half of said ball is receivable in said detent of said other half of said ball, and said upper mating surface of each half of said ball abuts said lower mating surface of said other half of said ball. 9. The ball handle assembly of claim 6, wherein said ball is compressible. 10. The ball handle assembly of claim 6, wherein actuation of said clamping mechanism to said secured position causes said grip assembly to assert a compression force onto said ball to secure said ball to said boom, and wherein actuation of said clamping mechanism to said unsecured position causes said compression force to be released thereby allowing said ball to be translatable along a length of said boom. 11. The ball handle assembly of claim 6, wherein said grip assembly is rollable between about zero degrees and three hundred and sixty degrees)(360°) about said ball, said grip assembly is pitchable between about thirty degrees)(30°) in a forward direction and about thirty degrees)(30°) in a rearward direction relative to said ball, and said grip assembly is yawable between about thirty degrees)(30°) in a forward direction relative to said ball, and said grip assembly is yawable between about thirty)(30°) in a forward direction and about thirty degrees)(30°) in a rearward direction relative to said ball. 12. The ball handle assembly of claim 6, wherein said ball and said grip assembly are translatable along a length of said boom. 13. A handheld tool comprising: a boom having a first distal end and a second distal end;a powered mechanism operatively connected to said first distal end of said boom;an actuating assembly operatively connected to said second distal end of said boom, said actuating assembly operatively connected to said powered mechanism; anda ball handle assembly being selectively securable directly to said boom, wherein movement of said ball handle assembly relative to said boom is prevented when said ball handle assembly is secured to said boom, and wherein said ball handle assembly includes a ball formed of opposing halves, and said ball halves are attachable to each other, said boom being receivable between said opposing ball halves. 14. The handheld tool of claim 13, wherein said ball handle assembly has four degrees of movement relative to said boom. 15. The handheld tool of claim 14, wherein said ball handle assembly is: (1) translatable along a length of said boom, (2) rollable about a longitudinal axis of said boom, (3) pitchable about an axis horizontally perpendicular to said longitudinal axis of said boom, and (4) yawable about an axis vertically perpendicular to said longitudinal axis of said boom. 16. The handheld tool of claim 15, wherein said ball handle assembly is rollable between about zero degrees and three hundred sixty degrees)(360°) about said longitudinal axis of said boom, said ball handle assembly is pitchable between about thirty degrees)(30°) in a forward direction and about thirty degrees)(30°) in a rearward direction relative to said boom, and said ball handle assembly is yawable between about thirty degrees)(30°) in a forward direction and about thirty degrees)(30°) in a rearward direction relative to said boom.
