摘要： An improved pivot pin for a firearm may provide a head, shank, and/or openings. The improved pivot pin may also provide a modified central channel, an installation point, and/or installation channel to allow for tool-free or tool-less installation. Further, the improved pivot pin may provide a removal channel to allow the pivot pin to easily be removed from the lower receiver without tools. An improved takedown pin for a firearm may provide a head, shank, and/or openings. The improved takedown pin may also provide a modified center channel and/or removal channel as well. A removal tool to aid removal of a pivot pin or takedown pin from a firearm may be generally shaped to conform or fit within the channel of the pivot or takedown pin. The width and height of the removal tool may be slightly smaller than the width and height of the channel of the pivot pin or takedown pin. The distal end of the removal tool may taper from a top surface to the bottom surface to form a sharp point or tip. A shank of any conventional or aftermarket pivot pin, takedown pin, or reinstallation tool may be modified to provide a storage cavity sized to receive the removal tool.

摘要： The invention relates to a hinge comprising a first part (11) that can be pivoted relative to a second part (12) about a pivot axis (a), wherein the first part (11) comprises at least one bore (13) and the second part (12) at least one recess (15a, 15b), wherein, in a final assembly position, at least pin one (17a, 17b) that is coaxial to the pivot axis (a), has a first longitudinal portion in the bore (13) and with a second longitudinal portion in the recess (15a, 15b), and the pin (17a, 17b) can be moved between a pre-assembly position, in which the pin (17a, 17b) is in the bore (13) or in the recess (15a, 15b) with a larger overlap with respect to the final assembly position, and the final assembly position.
The special feature is that at least one holding element (18) can extend through a passage (31) in a seat (28) in such a way that the pin (17a, 17b) can be moved by the holding element (18) from the pre-assembly position into the final assembly position and that, in the final assembly position, the holding element (18) is positioned in such a way that it prevents a return movement of the pin (17a, 17b) from the final assembly position into the pre-assembly position.-

摘要： Support strut assembly for supporting a casing of a functional unit of gas turbine is provided having a strut body for supporting the casing to ground, a ball pivot element mounted to the strut body and a rocker lever mounted to the ball pivot element. The rocker lever inserts into a bearing bore of a support body as part of the casing or ground, the rocker lever inserts into the bearing bore via clearance fit so a pivotal point is generated at a first contact area between the rocker lever and an inner surface of the bearing bore, the rocker lever pivots within the bearing bore around the pivotal point. An elastomeric springing damping element is mounted to the rocker lever between the rocker lever and the a support body providing centering force and damping pivoting of the rocker lever with respect to the support body around the pivotal point.

摘要： A rod and bracket assembly includes a bracket with a rod connected to the bracket via a fastener extending through a bracket hole. A bushing assembly is positioned at the bracket hole and includes a bushing having a bushing flange and a wear pad positioned between the bushing flange and an inner face of the bracket to prevent wear of the bracket and/or the rod in the event that the rod rolls about its own axis. A clevis assembly for a clevis and rod assembly includes a clevis having one or more clevis legs extending from a clevis base and a bushing assembly located at a clevis hole. The bushing assembly includes a bushing having a bushing flange and a wear pad disposed between the bushing flange and an inner face of the clevis leg to prevent wear of the clevis leg and/or the rod assembly.
