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.

What is claimed is: 1. A force dampening hitch assembly comprising: a towing attachment assembly, said towing attachment assembly being adapted for coupling to a towing vehicle; a trailer attachment assembly pivotally coupled to the towing attachment assembly, said trailer attachment assembly being adapted for coupling to a trailer assembly; and a shock absorbing assembly coupled between the towing attachment assembly and the trailer attachment assembly to dampen pivoting between the towing attachment assembly and the trailer attachment assembly; wherein said towing attachment assembly includes a main portion and a shock attachment arm extending from said main portion, said shock absorbing assembly extending between said shock attachment arm and said trailer attachment assembly; wherein said shock attachment arm extends from a proximal end of said main portion back towards a distal end of said towing attachment assembly; said shock absorbing assembly including a shock absorber having a first end pivotally coupled to said towing attachment assembly and a second end pivotally attached to said trailer attachment assembly; said trailer attachment assembly including a pair of flanges forming a generally L-shaped main section having a first end pivotally coupled to said towing attachment assembly; and a trailer attachment means extending from a second end of said generally L-shaped main section for coupling to the trailer assembly. 2. The force dampening hitch assembly of claim 1 wherein said second end of said shock absorber is pivotally coupled to a junction between said pair of flanges forming said L-shaped main section. 3. A force dampening hitch assembly comprising: a towing attachment assembly, said towing attachment assembly being adapted for coupling to a towing vehicle; a trailer attachment assembly pivotally coupled to the towing attachment assembly, said trailer attachment assembly being adapted for coupling to a trailer assembly; and a shock absorbing assembly coupled between the towing attachment assembly and the trailer attachment assembly to dampen pivoting between the towing attachment assembly and the trailer attachment assembly; wherein said towing attachment assembly includes a main portion and a shock attachment arm extending from said main portion, said shock absorbing assembly extending between said shock attachment arm and said trailer attachment assembly; wherein said shock attachment arm extends from a proximal end of said main portion back towards a distal end of said towing attachment assembly; and said shock absorbing assembly including an air bag assembly having a first end pivotally coupled to said shock attachment arm and a second end pivotally attached to said trailer attachment assembly. 4. The force dampening hitch assembly of claim 3 further comprising: said trailer attachment assembly including an arcuate section having a first end pivotally coupled to said towing attachment assembly; and a trailer attachment means extending from a second end of said arcuate section for coupling to the trailer assembly. 5. The force dampening hitch assembly comprising: a towing attachment assembly, said towing attachment assembly being adapted for coupling to a towing vehicle; a trailer attachment assembly pivotally coupled to the towing attachment assembly, said trailer attachment assembly being adapted for coupling to a trailer assembly; and a shock absorbing assembly coupled between the towing attachment assembly and the trailer attachment assembly to dampen pivoting between the towing attachment assembly and the trailer attachment assembly; wherein said towing attachment assembly includes a main portion and a shock attachment arm extending from said main portion, said shock absorbing assembly extending between said shock attachment arm and said trailer attachment assembly; wherein said shock attachment arm extends from a proximal end of said main portion back towards a distal end of said towing attachment assembly; and said proximal end being alignable with a main section of said trailer attachment assembly, said main section having a hole alignable with a restriction aperture in said main portion; and a restriction pin insertable through said hole and said aperture for restricting a range of pivoting between said towing attachment assembly and said trailer attachment assembly. 6. The force dampening hitch assembly of claim 5 wherein said main portion of said towing attachment assembly has a wedge clamp for engaging a receiver hitch. 7. The force dampening hitch assembly of claim 5 wherein said shock absorbing assembly comprises a shock absorber having a first end pivotally coupled to said towing attachment assembly and a second end pivotally attached to said trailer attachment assembly. 8. The force dampening hitch assembly of claim 7 wherein said shock absorber is oriented at an angle between 35 and 55 degrees from vertical when said shock absorber is in a neutral position between being extended and being compressed. 9. The force dampening hitch assembly of claim 5 wherein said trailer attachment assembly includes a generally L-shaped main section having a first end pivotally coupled to said towing attachment assembly; and a trailer attachment means extending from a second end of said generally L-shaped main section for coupling to the trailer assembly. 10. The force dampening bitch assembly of claim 5, further comprising: said shock absorbing assembly including a shock absorber having a first end pivotally coupled to said towing attachment assembly and a second end pivotally attached to said trailer attachment assembly; said trailer attachment assembly including an arcuate section having a first end pivotally coupled to said trailer attachment assembly; and a trailer attachment means extending from a second end of said arcuate section for coupling to the trailer assembly. 11. The force dampening hitch assembly of claim 10 wherein said second end of said shock absorber is pivotally coupled to a medial portion of said arcuate section such that said shock absorber is oriented at an angle between 35 and 55 degrees from vertical when said shock absorber is in a neutral position between being extended and being compressed. 12. The force dampening hitch assembly of claim 5 further comprising: said shock absorbing assembly including a shock absorber having a first end pivotally coupled to said shock attachment arm and a second end pivotally attached to said trailer attachment assembly. 13. The force dampening hitch assembly of claim 12 wherein said shock attachment arm is arcuate. 14. The force dampening hitch assembly of claim 13 wherein said second end of said shock absorber is positioned vertically below said proximal end of said main portion of said towing attachment assembly. 15. The force dampening hitch assembly of claim 5 wherein a second end of said shock absorbing assembly is positioned vertically below said main portion of said towing attachment assembly; wherein a first end of said shock absorbing assembly is pivotally coupled to a lower area of a main section of said trailer attachment assembly. 16. The force dampening hitch assembly of claim 15 wherein a longitudinal axis of said shock absorbing assembly is positioned at an angle between 5 and 15 degrees from horizontal. 17. The force dampening hitch assembly of claim 5 wherein said aperture and said hole are different sizes to prevent total restriction of pivoting between said towing attachment assembly and said trailer attachment assembly.
