摘要： The damper (10) includes a damper housing (14) and a piston assembly (12) reciprocating therein. The damper housing (14) includes an attachment device (22) formed of an interior partially circular wall (16) with a triangular cross section thereby forming an interior partially circular apex (24) for engaging a cylindrical boss (100). This allows the damper (10) to rotate about an axis of the interior partially circular wall (16) and pivot about an axis perpendicular to the rotational axis. Additionally, the piston assembly (12) includes a detent protrusion (64) formed from a stem (66) supporting a head (68), the radius of the head (68) being greater than that of the stem (66). The detent protrusion (64) is engaged by a keyhole-shaped aperture (200) with a first portion (204) with a radius of curvature substantially equal to that of the stem (66) and a second portion (202) with a radius of curvature substantially equal to that of the head (68). The detent protrusion (64) can therefore rotate within the keyhole-shaped aperture (200). Additionally, the cap of the damper housing (14) is formed of elastic O-rings (50) to allow the piston assembly (12) to rotate within the damper housing (14).

摘要： The damper (10) includes a piston assembly (14) which travels within a cylindrical damper housing (12) between an extended position and a retracted position. A transverse channel (28) is formed proximate to the open end of the damper housing (12). A latching diamond (30) travels within the transverse channel. The piston assembly (14) includes a piston shaft (52) with a camming wall sub-assembly formed thereon which engages the latching diamond (34) so that the piston assembly (14) is latched in a "push-push" configuration in the extended position. In this latched configuration, the latching diamond (34) is detent engaged by a concave detent apex (122) formed on an island which includes a longitudinally chamfered portion. Additionally, the flexibility of the island (92) in which the concave detent apex (122) is formed may be increased by transverse passageways or "cored-out" areas (128) in the piston shaft immediately adjacent to the island. While the open latched configuration is normally released by incrementally extending and then releasing the piston assembly, it is possible that a user will attempt to release the open latched configuration by urging the piston assembly toward the retracted position. In this case, the island flexes and the latch diamond travels over a longitudinally chamfered portion of the concave detent apex free of damage to the island, the latch diamond, and other portions of the damper.

摘要： The damper (10) includes a damper housing (14) and a piston assembly (12) reciprocating therein. The damper housing (14) includes an attachment device (22) formed of an interior partially circular wall (16) with a triangular cross section thereby forming an interior partially circular apex (24) for engaging a cylindrical boss (100). This allows the damper (10) to rotate about an axis of the interior partially circular wall (16) and pivot about an axis perpendicular to the rotational axis. Additionally, the piston assembly (12) includes a detent protrusion (64) formed from a stem (66) supporting a head (68), the radius of the head (68) being greater than that of the stem (66). The detent protrusion (64) is engaged by a keyhole-shaped aperture (200) with a first portion (204) with a radius of curvature substantially equal to that of the stem (66) and a second portion (202) with a radius of curvature substantially equal to that of the head (68). The detent protrusion (64) can therefore rotate within the keyhole-shaped aperture (200). Additionally, the cap of the damper housing (14) is formed of elastic O-rings (50) to allow the piston assembly (12) to rotate within the damper housing (14).
摘要翻译：阻尼器（10）包括阻尼器壳体（14）和在其中往复运动的活塞组件（12）。阻尼器壳体（14）包括由具有三角形横截面的内部部分圆形壁（16）形成的附接装置（22），从而形成用于接合圆柱形凸台（100）的内部部分圆形顶点（24）。这允许阻尼器（10）围绕内部部分圆形壁（16）的轴线旋转并且围绕垂直于旋转轴线的轴线枢转。另外，活塞组件（12）包括由支撑头部（68）的杆（66）形成的制动突起（64），头部（68）的半径大于杆（66）的半径。锁定突起（64）由键孔（200）与第一部分（204）接合，第一部分（204）的曲率半径基本上等于杆（66）的曲率半径，第二部分（202）的半径曲率基本上等于头部（68）的曲率。因此，止动突起（64）可以在锁眼形孔（200）内旋转。此外，阻尼器壳体（14）的盖由弹性O形环（50）形成，以允许活塞组件（12）在阻尼器壳体（14）内旋转。
