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 magnetic tool holder includes a body having a bottom and side walls defining an elongate central channel, wherein the bottom defines a first plane and ends of the side walls define a second plane, wherein the body further includes side edges laterally extending from said side walls in the second plane, and outer side walls extending from the side edges back to the first plane; and at least one magnet in the elongate central channel, the at least one magnet having a tool securing surface positioned substantially coplanar with the second plane. The outer...

1. A magnetic tool holder configured to be magnetically secured to a ferrous support surface, comprising: a body having a bottom defining a first securing surface and a pair of inner side walls defining an elongate central channel therebetween, wherein the first securing surface defines a first plane and upper ends of the pair of inner side walls define a second plane, wherein the body further comprises a pair of side edges, each one of said pair of side edges laterally extending outward from a corresponding one of said pair of inner side walls in the second plane away from said elongate central channel, and a pair of outer side walls each extending from a corresponding one of the side edges back to the first plane, each of said pair of outer side walls being spaced apart from the first securing surface to define a void between each of said pair of outer side walls and the first securing surface, the first securing surface and bottom ends of the pair of outer side walls are configured to form a three point contact with the ferrous surface in the first plane; andat least one magnet in the elongate central channel, said at least one magnet having a bottom surface and an opposite second securing surface, said bottom surface located within the elongate central channel facing said bottom of the body;said three point contact is configured to produce a first magnetic attraction force between said at least one magnet and the ferrous support surface;said pair of side edges in said second plane and said second securing surface of the at least one magnet are configured to produce a second magnetic attraction force between said at least one magnet and a ferrous tool surface, said first magnetic attraction force is stronger than said second attraction force. 2. The magnetic tool holder of claim 1, wherein said body portion is constructed from a ferrous material whereby such that said bottom and said outer side walls are polarized by said at least one magnet so that said body can be releasably secured in said first plane to the ferrous support surface. 3. The magnetic tool holder of claim 1, wherein said at least one magnet comprises a plurality of magnets each having opposed flat surfaces defining north and south pole surfaces, and wherein said plurality of magnets are positioned along said elongate central channel with alternating north and south pole surfaces defining said second securing surface. 4. The magnetic tool holder of claim 1, wherein said bottom, said pair of inner side walls, said pair of side edges and said pair of outer side walls are formed from a single sheet of ferrous material. 5. The magnetic tool holder of claim 1, further comprising: a clip pivotably mounted to the body into a release position wherein a portion of the clip extends beyond the first plane and is configured to push the body away from said ferrous support surface when the body is magnetically secured to the ferrous support surface. 6. The magnetic tool holder of claim 5, wherein said clip is loop shaped. 7. The magnetic tool holder of claim 1, wherein said second securing surface of the at least one magnet is positioned below said second plane between said first plane and said second plane. 8. The magnetic tool holder of claim 1, wherein said second magnetic attraction force acts to secure the ferrous tool surface to said magnetic tool holder, and said first magnetic attraction force acts to secure said magnetic tool holder to said ferrous support surface. 9. The magnetic tool holder of claim 1, wherein said second securing surface of the at least one magnet is positioned substantially coplanar with said second plane. 10. A magnetic tool holder configured to be magnetically secured to a ferrous support surface, comprising: a body made from a ferrous material having a bottom defining a first securing surface and a pair of inner side walls defining an elongate central channel therebetween, wherein the first securing surface of the body defines a first plane and upper end surfaces of the pair of inner side walls define a second plane, the body further including a pair of side edges, each one of said pair of side edges laterally extending outward from a corresponding one of said pair of inner side walls in the second plane away from said elongate central channel; the body further including a pair of outer side walls each extending from a corresponding one of the side edges back to the first plane, each of said pair of outer side walls being spaced apart from the first securing surface to define a void between each of said pair of outer side walls and the first securing surface, the first securing surface and bottom ends of the pair of outer side walls are configured to form a three point contact with the ferrous support surface in the first plane;at least one magnet in the elongate central channel, said at least one magnet having a first magnet surface and an opposite second magnet surface, said first magnet surface located within the elongate central channel facing said bottom of the body, and said second magnet surface positioned below said second plane between said first plane and said second plane; anda clip having a first bottom end and a second bottom end, wherein the first bottom end of the clip extends through one inner side wall from said pair of inner side walls and the second bottom end of the clip extends through the other inner side wall from said pair of inner side walls to pivotably mount the clip to the body, wherein the clip is configured to rotate relative to the body to push the body away from said ferrous support surface. 11. The magnetic tool holder of claim 10, wherein: said first magnet surface and said first securing surface are configured to produce a first magnetic attraction force between said at least one magnet and the ferrous support surface;said pair of side edges in said second plane and said second magnet surface are configured to produce a second magnetic attraction force between said at least one magnet and a ferrous tool surface; andsaid first magnetic attraction force is stronger than said second attraction force. 12. The magnetic tool holder of claim 11, wherein said second magnetic attraction force is configured to secure the ferrous tool surface of a tool to said magnetic tool holder, and said first magnetic attraction force is configured to secure said magnetic tool holder to said ferrous support surface. 13. The magnetic tool holder of claim 10, wherein said bottom and said outer side walls are polarized by said at least one magnet so that said body can be releasably secured in said first plane to the ferrous support surface. 14. The magnetic tool holder of claim 10, wherein said bottom, said pair of inner side walls, said pair of side edges and said pair of outer side walls are formed from a single sheet of ferrous material. 15. The magnetic tool holder of claim 10, wherein said at least one magnet comprises a plurality of magnets each having opposed flat surfaces defining north and south pole surfaces, and wherein said plurality of magnets are positioned along said channel with alternating north and south pole surfaces defining said second magnet surface.
