Double pivoting tilt joint
The invention provides a double pivot tilt joint for connecting two shafts for synchronous rotation and for tilting movement relative to one another. The double pivot tilt joint includes a first shaft member and a first pivot pin extending at least partially through the first shaft member. The double pivot tilt joint also includes a pivot block receiving the first pivot pin such that the first shaft member and the pivot block are pivotally coupled to one another about the first pivot pin. The double pivot tilt joint also includes a second pivot pin extending at least partially through the pivot block transverse to the first pivot pin. The double pivot tilt joint also includes a second shaft member receiving the second pivot pin such that the pivot block and the second shaft member are pivotally coupled to one another about the second pivot pin. The double pivot tilt joint also includes a groove defined by the first pivot pin and receiving the second pivot pin.
1. A double pivot tilt joint comprising:
a first shaft member;
a first pivot pin extending at least partially through said first shaft member;
a pivot block receiving said first pivot pin such that said first shaft member and said pivot block are pivotally coupled to one another about said first pivot pin;
a second pivot pin extending at least partially through said pivot block transverse to said first pivot pin and including an outer surface;
a second shaft member receiving said second pivot pin such that said pivot block and said second shaft member are pivotally coupled to one another about said second pivot pin; and
a groove defined by said first pivot pin with said groove being annular and having a shape corresponding to said outer surface of said second pivot pin and with said groove receiving said second pivot pin.
2. The double pivot tilt joint of claim 1 wherein said groove is further defined as extending fully around said first pivot pin.
3. The double pivot tilt joint of claim 1 wherein said groove is further defined as being substantially centered with respect to said first pivot pin.
4. The double pivot tilt joint of claim 1 wherein said outer surface is cylindrical and said shape of said groove is semi-circular.
5. The double pivot tilt joint of claim 1 wherein said second pivot pin is fixed to said second shaft member.
6. The double pivot tilt joint of claim 5 wherein said second pin is further defined as being staked to said second shaft member.
7. The double pivot tilt joint of claim 5 wherein said second pin is further defined as being press fit to said second shaft member.
8. The double pivot tilt joint of claim 1 wherein said first pivot pin and said second pivot pin are slidably engaged with said pivot block.
9. A double pivot tilt joint comprising:
a first shaft member;
a first pivot pin having a longitudinal axis and extending at least partially through said first shaft member and slidably engaged along said longitudinal axis with said first shaft member;
a pivot block slidably receiving said first pivot pin such that said first shaft member and said pivot block are pivotally coupled to one another about said first pivot pin;
a second pivot pin extending at least partially through said pivot block transverse to said first pivot pin and slidable engaged with said pivot block;
a second shaft member receiving said second pivot pin such that said pivot block and said second shaft member are pivotally coupled to one another about said second pivot pin and wherein said second pivot pin is fixed to said second shaft member; and
a groove defined by said first pivot pin and receiving said second pivot pin.
10. The double pivot tilt joint of claim 9 wherein said groove is annular.
11. The double pivot tilt joint of claim 10 wherein said groove is further defined as extending fully around said first pivot pin.
12. The double pivot tilt joint of claim 9 wherein said second pivot pin includes an outer surface and wherein a shape of said groove corresponds to said outer surface.
13. The double pivot tilt joint of claim 12 wherein said outer surface is cylindrical and said shape of said groove is semi-circular.
14. The double pivot tilt joint of claim 9 wherein said second pin is further defined as being staked to said second shaft member.
15. The double pivot tilt joint of claim 9 wherein said second pin is further defined as being press fit to said second shaft member.
