Link between two mechanical members
View Patent ↗A rigid link of adjustable length includes a yoke with a transversal stud. The stud is mounted on the yoke with two bearings, each inside a through-orifice in the yoke. The axis of the stud is offset from the axis of the bearings whereby the link includes a stopping device in order to lock the stud in at least two different positions, relative to the yoke.
1. A rigid link of adjustable length, said rigid link comprising:
a ring configured to receive a fastening element;
a stem that extends from the ring to a yoke that includes a first tab and a second tab that are joined together at the stem, said first tab including a first through-orifice and said second tab including a second through-orifice, each of said first tab and said second tab including a first outer face and a second outer face, the second outer face being recessed from the first outer face so as to define a plane surface that extends from the first outer face to the second outer face;
a first bearing located in said first through-orifice, said first bearing including a first bearing axis;
a second bearing located in said second through-orifice, said second bearing including a second bearing axis, said first and second bearing axes being collinear;
a transversal stud mounted between said first and second bearings and on the yoke via said first and second bearings, said transversal stud including a stud axis that is offset from the first and second bearing axes by a set distance, wherein an operative distance between said ring and said stud axis is adjustable by rotation of said stud about the bearing axis between at least two different angular positions, and
wherein each of said first and second bearings includes surfaces forming stops that respectively engage said plane surfaces of said first tab and of said second tab so as to prevent rotation of the transversal stud relative to the yoke in said at least two different angular positions.
2. A rigid link according to claim 1 , wherein at least one of said first and second bearings is formed homogeneously with the transversal stud.
3. A rigid link according to claim 1 , wherein each of said first and second bearings includes at least four surfaces, each forming a stop configured to respectively engage said plane surfaces of said first tab and of said second tab.
4. A rigid link according to claim 3 , wherein the at least four surfaces are arranged as a polygon.
5. A rigid link according to claim 4 , wherein the polygon includes four to six sides.
6. A rigid link according to claim 1 , wherein said first tab of said yoke, said second tab of said yoke, and said stem of said yoke are formed homogeneously so as to not include any boundaries therebetween.
7. A rigid link according to claim 1 , wherein the first bearing is homogeneously formed with said transversal stud and said second bearing is slidingly mounted on said transversal stud.
8. A rigid link according to claim 1 , wherein said yoke, said first and second bearings, and said transversal stud form only three separable parts.
9. A rigid link according to claim 8 , wherein said first tab, said second tab, and said stem are formed homogeneously with said yoke, and said first bearing is formed homogeneously with said transversal stud.
10. A rigid link according to claim 1 , wherein said plane surface of said first tab and said plane surface of said second tab are configured to lock the transversal stud in three different angular positions, relative to the yoke.
11. A rigid link according to claim 10 , wherein a distance between said ring and said stud axis differs for each of said three different angular positions.
12. A rigid link according to claim 1 , wherein said plane surface of said first tab and said plane surface of said second tab each extend substantially perpendicular to each of said tabs.
13. A rigid link according to claim 1 , wherein a distance between said ring and said stud axis is indexed to each of the at least two different angular positions.
14. A rigid link according to claim 1 , wherein said plane surface of said first tab directly contacts one of the surfaces forming stops of the first bearing, and wherein said plane surface of said second tab directly contacts one of the surfaces forming stops of the second bearing.
15. A rigid link according to claim 1 , wherein said first and second outer faces are substantially parallel.
16. A rigid link according to claim 1 , wherein said plane surface of said first tab extends substantially parallel to the stud axis.
17. A rigid link according to claim 16 , wherein said plane surface of said second tab extends substantially parallel to the stud axis.
18. A rigid link according to claim 1 , further comprising a ball-joint that is fitted in the ring.
