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.

초록

A cart for supporting cargo thereon has wheels at one end and a handle at an opposite end to allow the cart to be transported manually on a ground surface. The cart has an upper bracket and a pair of laterally spaced lower brackets on one of its sides for mounting the cart to a three-point hitch mechanism, and/or a pair of fork lift brackets to allow the cart to be lifted from the ground surface and transported over the ground surface.

I claim: 1. A non-powered manually transportable cart mountable to a three-point hitch mechanism, comprising: a frame having first and second sides extending between first and second ends; a platform carried by said frame for supporting cargo, said frame and said platform defining a horizontally open cargo space extending from said first end to said second end and from said first side to said second side; a handle attached to said first end of said frame; a pair of wheels operably attached adjacent said second end of said frame opposite said handle to facilitate transporting said cart by hand on a ground surface; an upper bracket operably attached to said first side of said frame, said upper bracket arranged for attachment to a center link of the three-point hitch mechanism; a pair of lower brackets operably attached to said first side a predetermined distance beneath said upper bracket, said lower brackets arranged for attachment to a pair of laterally spaced draft links of the three-point hitch mechanism; and a pair of fork lift brackets attached to said frame in laterally spaced relation from one another to provide channels to receive a pair of forks of a fork lift to facilitate transporting said cart via the fork lift, said fork lift brackets having a bottom surface arranged to engage the ground surface when the cart is in a rest position. 2. The cart of claim 1 wherein said fork lift brackets are arranged to receive the forks transversely between said ends. 3. The cart of claim 1 wherein said wheels are spaced from the ground surface when said bottom surface is engaged with the ground surface. 4. The cart of claim 1 further comprising a pair of caster assemblies attached to opposite sides of said frame for rolling engagement with the ground surface. 5. The cart of claim 4 wherein the cart has a bottom surface and said caster assemblies are movable between a retracted position and an extended position, said wheels being raised above a plane defined by said bottom surface and out of engagement with the ground surface when in the retracted position and lowered below said plane when in the extended position for rolling engagement with the ground surface. 6. A cart transportable manually on a ground surface and mountable to a three-point hitch mechanism for transporting the cart via the three-point hitch mechanism in a raised position above the ground surface, comprising: a frame having first and second sides extending between first and second ends and a bottom surface arranged for engagement with the ground surface, said frame defining a horizontally open cargo space extending from said first end to said second end and from said first side to said second side; a handle attached to one end of said frame; a pair of wheels having an outer radius rotatable about an axis, said wheels being operably attached adjacent the end of said frame opposite said handle so that said axis is spaced from said bottom surface a distance greater than said outer radius so that said wheels are substantially spaced from the ground surface when said bottom surface is engaged with the ground surface, said wheels being brought into rolling engagement with the ground surface when the cart is tilted relative to the ground surface; an upper bracket attached to said first side of said frame, said upper bracket arranged for attachment to a central link of the three-point hitch mechanism; and a pair of lower brackets attached to said first side a predetermined distance beneath said upper bracket, said lower brackets arranged for attachment to a pair of laterally spaced draft links of the three-point hitch mechanism. 7. The cart of claim 6 further comprising a pair of fork lift brackets attached to said frame in laterally spaced relation from one another to provide channels to receive a pair of forks of a fork lift to facilitate transporting said cart via the fork lift. 8. The cart of claim 6 further comprising a pair of walls extending upwardly from said ends, a wall extending upwardly from said first side, and a cover extending over said walls generally covering said open cargo space, said second side being generally horizontally open between said first and second ends. 9. The cart of claim 6 wherein said wheels on said cart are out of rolling engagement from the ground surface when said cart is transported via the three-point hitch mechanism. 10. The cart of claim 6 further comprising a pair of caster assemblies attached to opposite sides of said frame for rolling engagement with the ground surface. 11. The cart of claim 10 wherein said caster assemblies are movable between a retracted position out of engagement with the ground surface and an extended position for rolling engagement with the ground surface. 12. A non-motorized cart transportable manually on a ground surface and by a fork lift in a raised position above the ground surface, comprising: a frame having first and second sides extending between first and second ends and a bottom surface arranged for engagement with the ground surface, said frame defining a horizontally open cargo space extending from said first end to said second end and from said first side to said second side; a handle attached to one end of said frame; a pair of wheels having an outer radius rotatable about an axis, said wheels being operably attached adjacent the end of said frame opposite said handle so that said axis is spaced from said bottom surface a distance greater than said outer radius so that said wheels are substantially spaced from the ground surface when said bottom surface is engaged with the ground surface, said wheels being brought into rolling engagement with the ground surface when the cart is tilted relative to the ground surface; and a pair of fork lift brackets attached to said frame in laterally spaced relation from one another to provide channels to receive a pair of forks of the fork lift to facilitate transporting said cart via the fork lift. 13. The cart of claim 12 further comprising an upper bracket attached to said first side of said frame, said upper bracket arranged for attachment to a central link of a three-point hitch mechanism and a pair of lower brackets attached to said first side a predetermined distance beneath said upper bracket, said lower brackets arranged for attachment to a pair of laterally spaced draft links of the three-point hitch mechanism. 14. The cart of claim 12 wherein said fork lift brackets are arranged to receive the forks transversely between said ends. 15. The cart of claim 12 further comprising a pair of caster assemblies attached to said first and second sides of said frame for rolling engagement with the ground surface. 16. The cart of claim 15 wherein said caster assemblies are movable between a retracted position out of engagement with the ground surface and an extended position for rolling engagement with the ground surface. 17. The cart of claim 1 further comprising a pair of wheel mounts, said wheel mounts having a first end attached to said frame and said wheels being operably attached to a second end, wherein said wheel mounts outwardly extend from said frame in a generally mirrored relation to one another. 18. The cart of claim 12 further comprising a pair of wheel mounts, said wheel mounts having a first end attached to said frame and said wheels being operably attached to a second end, wherein said wheel mounts outwardly extend from said frame in a generally mirrored relation to one another.
