摘要:
A metallic ball pin of a ball-and-socket joint, preferably one with high load-bearing capacity, for motor vehicles with a surface ball part 22 containing grooves 60, 62 for receiving lubricant designed at one end of a pin member 10, 30, 40. To improve its functional properties and to reduce its manufacturing costs, a surface ball part 22 with a joint ball surface 25 is molded to a joint ball core portion 16 using an injection molding process.

A structure for a ball-and-socket joint connector is provided, including a connecting element, an encasing unit and a fastening unit. The connecting unit includes a ball-shaped connecting element at one end. The connecting element is placed inside the encasing unit to form a ball-and-socket joint structure. The fastening unit is engaged to the outer circumference of the top of the encasing unit to fasten the connecting unit and the encasing unit after the adjustment. The connecting element includes two layers of materials with different hardness. The outer layer is softer than the inner layer as to increase the friction between the connecting element and the encasing unit after the fastening unit is applied to fasten the connecting unit and the encasing unit.

A swiveling fitting for multi-directional movement includes a housing having a bore therethrough to accommodate a button shaft. A ball housing receives at least a portion of the button shaft. The ball housing has at least one ball recess to accommodate at least one ball. A locking sphere receives at least a portion of the ball housing. The locking sphere has at least one groove to accommodate the at least one ball, and a baseplate for moveably securing the locking sphere. The baseplate is releasably securable to a substrate.

One embodiment of the invention provides a post extension system frame assembly for mounting fixtures within a recess in a wall or ceiling and that can be adjusted and installed with minimal time and effort. One feature of the invention provides a post extension and angling mechanism that can be manually installed and/or adjusted to set the depth, direction and angle of an audio device so as to be able to position the sound dispersion axis of the audio device (e.g., speaker, tweeter, woofer, audio transducer, etc.) directly towards a listener.

A universal joint including a first tubular member, a second tubular member, and an intermediate tubular member for connecting the first and second tubular members, the intermediate tubular member having at one end an outer spherical part and at the other end a cylindrical part, the first tubular member having at one end an inner spherical part in which the outer spherical part of the intermediate tubular member is inserted to move universally, and the second tubular member having at one end a hole in which the cylindrical part of the intermediate tubular member is rotatably inserted, the inner spherical part having an axis oblique at an angle to an axis of the outer spherical part of the intermediate tubular member.
摘要:
A ball joint which uses spherical rollers to reduce the torque friction which tends to inhibit the rotation of the ball within a ball joint assembly. Two sets of spherical rollers are captivated between the ball and two liner rings in the ball joint housing. The ball has two annular raceways which act as the inner raceways for the spherical rollers. Two liner rings have internal diameters which match the configuration of the spherical rollers and which act as outer raceways for the spherical rollers. The two liner rings have external threads and are installed into the housing which has matching internal threads.

A ball joint (10) connects a first vehicle part (12) to a second vehicle part (14) and enables relative movement between the first and second vehicle parts. The ball joint (10) includes a housing (30) that defines a chamber (40). A first stud (80) has a first portion (84) fixedly connected to the first vehicle part (12) and an opposite second portion (82) received in the chamber (40). A second stud (120) has a first portion (124) fixedly connected to the second vehicle part (14) and a second portion (122) received in the chamber (40). A spherical member (160) is disposed in the chamber (40) between the second portions (82 and 122) of the first and second studs (80 and 120) in mating and abutting engagement with the second portions of the studs. The first and second studs (80 and 120) each are movable independently in pivotal and rotational directions relative to the housing (30).
摘要:
A joint mechanism and connector includes a rounded member having at least one concavity and which is connected to a first part, at least one actuator having a tip that is received in the concavity to lock a second part connected to the actuator to the first part. The rounded member has a recess defined thereon which receives spherical members on the rounded member. The actuator tip is received in concavities defined by the spherical members.
