Patent

CA 2711999

A pivot joint includes a first member pivotally connected to a second member by a pivot pin. The first member includes a first surface, a second surface, and an opening extending therethrough. The opening is surrounded by a plurality of embossments protruding from the first surface and defining an embossment height. A second member includes a first surface, a second surface, and an opening extending therethrough. The pivot pin extends through the openings in the first and second members and includes a shoulder defining a shoulder height equal to the embossment height. The first surface of the second member engages the embossments and the shoulder to control axial free-play of the pivot joint. An inner surface of the opening in the first member engages the pivot pin to control diametrical free-play of the pivot joint.

La présente invention concerne une articulation rotoïde comportant un premier organe relié en pivotement à un second organe par un axe de pivotement. Le premier organe comporte une première surface, une seconde surface, et une ouverture sétendant à travers celles-ci. Louverture est entourée par une pluralité de bossages en saillie depuis la première surface et définissant une hauteur de bossage. Un second organe comprend une première surface, une seconde surface, et une ouverture sétendant à travers celles-ci. Laxe de pivotement se prolonge à travers les ouvertures dans les premier et second organes et comporte un épaulement définissant une hauteur dépaulement égale à la hauteur de bossage. La première surface du second organe engage les reliefs et lépaulement pour contrôler le libre débattement axial de larticulation rotoïde. Une surface intérieure de louverture dans le premier organe engage laxe de pivotement pour contrôler le libre débattement diamétral de larticulation rotoïde.
