  • Patent number: 6713223
    Abstract: A device for articulated connection between a control element and a control rod having a ball head comprising a main body attachable to the control element. The main body envelops a locating section providing positive location for the ball head and has an opening area through which the control rod extends when the device is assembled. According to the invention, the locating section is in two parts whereby the main body forms a part into which the ball head can be introduced through a joint duct located outside the opening, while a molding insertable into the joint duct forms the other part of the locating section. As a result, a simple device is created, guaranteeing connection between the control element and the control rod which is backlash-free or has little backlash.

  • Patent number: 6505989
    Abstract: A ball joint includes a socket that defines an outer surface having multiple, annular, smoothly-curved teeth. A ball is received in the socket, and the socket is received in a recess of a housing. This recess defines complementarily-shaped annular, smoothly-curved teeth. The crests of the teeth are arranged along lines that are angled with respect to the insertion axis such that the teeth of the socket pass over the teeth of the housing without an interference fit therebetween during an early stage of assembly. It is only at the end of assembly that the teeth of the socket mechanically interfere with the teeth of the housing to create the desired snap lock. In one example, the ball joint housing forms a recess that receives a rod. The inner surface of this recess undulates and includes gradually converging surfaces and gradually diverging surfaces with respect to the rod axis.

  • Publication number: 20030002914
    Abstract: A construction of a cover for ball joint for application in connections of both angular and rotational movements of automotive vehicles. The cover is constructed with a boss in its outermost circumference so that when assembling the ball joint, the bearing flange that is inserted in the interior of the box, that is closed by the cover, does not burst. Moreover, the bearing is maintained fixed to the assembling place as it is desired, for the perfect operation of the ball joint. The cover constructed in this manner functions as a limiting piece in the assembling process, so that, even if too strongly pressed upon the bearing flange, it may burst only the outermost part of the bearing flange preserving its major part, that will be retained between the recess provided in the interior of the ball joint box and the space immediately posterior to the boss constructed in the outermost circumference of the cover, thus keeping the bearing fixed to its place.

  • Patent number: 6481914
    Abstract: A coupling mechanism secures a radiographic source connector to a drive assembly to prevent unintentional release. The source connector includes a cup sleeve with a sleeve slot cut along its axis. The sleeve is spring-loaded to capture the ball end of a drive assembly by applying a positive locking force from the spring. The sleeve slot provides clearance for the neck of the ball end of the drive connector ball. This clearance allows the source connector to pivot approximately 90° without detaching from the drive cable at any angle or orientation. The source connector cannot be disconnected from the drive assembly due to a force applied in any direction. The only mechanism for release is to intentionally move the sleeve in a direction opposite the urging of the spring and then remove the drive connector ball.

  • Patent number: 4895472
    Abstract: The invention relates to a disassemblable ball and socket joint, of the type positioned by a single operation. The ball carried by a journal enters a hemispherical housing of the ball cage, a C-shaped retaining ring partly surrounds the cage and penetrates its wall through two slots which lead into the introduction channel of the ball into its housing, converging outwards. To avoid corrosion risks and to facilitate disassembly, the ring exerts upon the cage a force parallel to the axis of the channel at two points located on either side of the plane of symmetry in the summital region, and it also urges the interior face of the slots, by virtue of protuberances provided near its ends, for example, so that it is not normally in contact with the ball or its journal.

  • Patent number: 4778196
    Abstract: In this improved ball-and-socket trailer hitch, the heavy coil spring, conventionally utilized to forwardly bias a latching collar, is eliminate; instead threaded means are provided to move the collar back and forth when it is rotated manually. Unlatching is much easier in the absence of strong spring bias on the collar, so the need for additional collar-actuating mechanism such as levers, handles and linkages, often required is conventional hitches, is eliminated. The collar may locked in a forward latched position by the inclusion of a pivoted, thumb-operated lock lever, which is spring loaded to automatically drop into the rear edge of the collar when the collar is moved into its latched position, and thus lock the collar in this latched position, constrained against rearward or rotational movement, to eliminate risk of trailer uncoupling due to unintended unlatching of the hitch. The lock lever may be adapted to accept a padlock to avoid trailer theft.
