Abstract
A ball-joint has a hollow housing, and a ball in contact with a socket in the housing; and a locking device is disposed between the largest diameter of the ball and the device which supports the locking device, so that the ball is restrained from moving off the ball socket when the pin shaft is pulled in the direction away from the ball socket. A plurality of locking rings is produced by fabricating a resiliently deformable longitudinal rod, forming the rod into a helix, and cutting the helix parallel to the longitudinal axis.
Claims5
In a ball-joint assembly, including a hollow housing having an opening on one side,
- comprising in combination:
- a generally hemispherical ball socket within said housing:
- a ball, including a part in contact with said socket;
- a pin shaft extending from said ball through said opening;
- supporting means in said housing near said opening;
- and a discontinuous elastically deformable, but operatively rigid and closed locking ring supported by said supporting means and at least partly surrounding a portion of said ball, having an inner width smaller than the largest diameter of the ball, and being positioned between said largest diameter of said ball and said supporting means, whereby the ball is restrained from being removed off said ball socket when said pin shaft is pulled in a direction away from said ball socket.
