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.

1. A folding arrangement of a walk-behind power tool, the folding arrangement comprising a hinge, having a first hinge part arranged for receiving an end of a first elongate member, and a second hinge part arranged for receiving an end of a second elongate member, the first and second hinge parts being pivotally interconnected about a hinge axis, so as to enable pivoting of the hinge between a folded position and a closed position,wherein the first hinge part has a first opening arranged for passing through a cable harness arriving from a channel or groove provided in the first elongate member,wherein the second hinge part has a second opening arranged for receiving the cable harness arriving from the first opening,wherein the first and second openings are facing each other when the hinge is in the closed position, andwherein at least one of the first and second hinge parts has a protruding portion, arranged for directing the cable harness towards the first and second openings upon pivoting the hinge from the folded position to the closed position. 2. The folding arrangement according to claim 1, wherein the protruding portion is arranged at a periphery of the first opening. 3. The folding arrangement according to claim 2, wherein a second protruding portion is arranged at a periphery of the second opening. 4. The folding arrangement according to claim 1, which folding arrangement furthermore comprises a flexible tubular cable harness protection means, arranged to extend between the first opening and the second opening and to cover the cable harness between the first opening and the second opening. 5. The folding arrangement according to claim 4, wherein the flexible tubular cable harness protection means is a coil spring. 6. The folding arrangement according to claim 4, wherein the flexible tubular harness protection means is a deformable sheath. 7. The folding arrangement according to claim 1, wherein, when the hinge is in the closed position, the protruding portion is substantially enclosed within the first hinge part or the second hinge part. 8. The folding arrangement according to claim 1, wherein the protruding portion comprises a curved cross-section to conform to the shape of the cable harness when the hinge is in the folded position. 9. The folding arrangement according to claim 1, wherein the protruding portion comprises a rigidity sufficient to resist deformation of the protruding portion by the cable harness during pivoting of the hinge from the folded position to the closed position. 10. The folding arrangement according to claim 1, wherein the second opening is provided in a projecting system of the second hinge part. 11. A handle assembly of a walk-behind power tool, the handle assembly comprising a folding arrangement, the folding arrangement comprising: a hinge comprising a first hinge part arranged for receiving an end of a first elongate member, and a second hinge part arranged for receiving an end of a second elongate member, the first and second hinge parts being pivotally interconnected about a hinge axis, so as to enable pivoting of the hinge between a folded position and a closed position,wherein the first hinge part has a first opening arranged for passing through a cable harness arriving from a channel or groove provided in the first elongate member,wherein the second hinge part has a second opening arranged for receiving the cable harness arriving from the first opening,wherein the first and second openings are facing each other when the hinge is in the closed position, andwherein at least one of the first and second hinge parts has a protruding portion, arranged for directing the cable harness towards the first and second openings upon pivoting the hinge from the folded position to the closed position. 12. The handle assembly according to claim 11, wherein the folding arrangement further comprises a flexible tubular cable harness protection means, arranged to extend between the first opening and the second opening and to cover the cable harness between the first opening and the second opening, and wherein the flexible tubular harness protection means is a deformable sheath. 13. The handle assembly according to claim 11, wherein, when the hinge is in the closed position, the protruding portion is substantially enclosed within the first hinge part or the second hinge part. 14. The handle assembly according to claim 11, wherein the protruding portion comprises a curved cross-section to conform to the shape of the cable harness when the hinge is in the folded position. 15. The handle assembly according to claim 11, wherein the protruding portion comprises a rigidity sufficient to resist deformation of the protruding portion by the cable harness during pivoting of the hinge from the folded position to the closed position. 16. The handle assembly according to claim 11, wherein the second opening is provided in a projecting system of the second hinge part. 17. A walk-behind power tool comprising a handle assembly, a working member, and a prime mover configured to drive the working member, the handle assembly comprising a folding arrangement, the folding arrangement comprising: a hinge comprising a first hinge part arranged for receiving an end of a first elongate member, and a second hinge part arranged for receiving an end of a second elongate member, the first and second hinge parts being pivotally interconnected about a hinge axis, so as to enable pivoting of the hinge between a folded position and a closed position,wherein the first hinge part has a first opening arranged for passing through a cable harness arriving from a channel or groove provided in the first elongate member,wherein the second hinge part has a second opening arranged for receiving the cable harness arriving from the first opening,wherein the first and second openings are facing each other when the hinge is in the closed position, andwherein at least one of the first and second hinge parts has a protruding portion, arranged for directing the cable harness towards the first and second openings upon pivoting the hinge from the folded position to the closed position. 18. The walk-behind power tool of claim 17, wherein the walk-behind power tool is a snow thrower, dethatcher, aerator, or sod cutter. 19. The walk-behind power tool of claim 17, wherein the walk-behind power tool is a lawn mower, and wherein the working member comprises a cutting blade. 20.
