ABSTRACT:
A tension-lock system for the spokes of a spoked wheel includes a nipple having both internal threads (which mate with the external threads at one end of a spoke) and external threads. A lock-nut having internal threads to mate with the external threads of the spoke nipple, and is at one end convex shaped. A washer which is at one end,concave shaped to mate with the convex surface of the nut. As the wheel is being assembled, the lock nut and washer are slid over the threaded end of the spoke. The threaded end of the spoke is then placed through the hole in the rim. The nipple is then threaded onto the threads of the spoke until the wheel is in a "trued position". The washer and lock nut are then tightened onto the nipple, and against the rim, thus preventing the nipple from turning on the spoke and thereby maintaining the wheel in the "trued position". Another variation of the tension-lock system for the spokes of a spoked wheel includes a lock nut having internal threads which mate with the external threads at one end of a spoke. A nipple which passes through a hole in the rim of the wheel also includes internal threads which also mate with the spoke threads. The nut locks against one end of the nipple after both nipple and nut have been threaded onto the spoke into a "trued position", thus preventing the nipple from turning on the spoke and thereby maintaining the spokes in the "trued position".
