摘要： A chain wear indicator measures the wear in a chain to determine if the chain needs to be replaced. The chain wear indicator includes a body portion with a first end, a second end and first and second sides extending between the first and second ends. The first side of the body portion measures a first predetermined amount of wear in the chain, while the second side of the body portion determines if a new chain is defective. Alternatively, the second side of the body portion measures a second predetermined amount of wear in the chain. Each side of the body portion has three protrusions. The first protrusion extends from the first end of the body portion and has a first roller engaging surface facing in a first direction. The second protrusion extends from the middle of the body portion and has a second roller engaging surface facing in a second direction which is substantially opposite the first direction. The first and second roller engaging surfaces are configured and spaced apart from each other by a distance corresponding a predetermined number of the chain links to place the chain under tension therebetween. The third protrusion extends from the second end of the body portion and has a third roller engaging surface facing in substantially the second direction. The third roller engaging surface is configured and spaced from the second roller engaging surface by a distance corresponding a predetermined number of the chain links plus a pre-selected amount of wear per link to determine if the chain is worn out and needs to be replaced.

摘要翻译： 链条磨损指示器测量链条中的磨损，以确定链条是否需要更换。 链条磨损指示器包括主体部分，其具有第一端部，第二端部以及在第一和第二端部之间延伸的第一和第二侧面。 主体部分的第一侧测量链中的第一预定磨损量，而主体部分的第二侧确定新链条是否有缺陷。 或者，身体部分的第二侧测量链中的第二预定量的磨损。 主体部分的每一侧具有三个突起。 第一突起从主体部分的第一端延伸并且具有面向第一方向的第一辊接合表面。 第二突起从主体部分的中部延伸并且具有面向第一方向的第二方向的第二辊接合表面。 第一和第二辊接合表面被构造成彼此隔开相应于预定数量的链节的距离，以将链条张紧在其间。 第三突起从主体部分的第二端延伸并且具有面向大致第二方向的第三辊接合表面。 第三辊接合表面被构造成与第二辊接合表面间隔一定距离，对应于预定数量的链节加上每链接预先选择的磨损量，以确定链条是否磨损并需要更换。

摘要： An adjustable vehicle parking stand is described. The parking stand includes first and second members. The first member has a first member axis defining an axial direction. The first member also a first engagement edge with a slope in the axial direction. The second member is rotatable about the first member axis and has a second engagement edge with a slope in-the axial direction. The second engagement edge abuttingly engages the first engagement edge.
