The disclosure describes a cable length adjuster. More specifically, it describes a cable length adjuster which is able to operate without a separate spring to bias a bolt into a position where said bolt engages a rod, this position being the locked position. This is achieved by having the bolt disposed in a window of a body, said bolt having legs extending through the window, said bolt being moveable in the window between the locked position and an open position. A winglet extends from each of said legs. Said winglets are made of a resilient material and abuts the sides of the windows which are adjacent to said legs. Said sides of the window are inclined such that the bolt is biased towards the locked position.
A new cable length adjuster for adjusting the effective length of an inner moveable member of an actuation cable assembly.
In a prior art solution, a locking 'bolt' is introduced in a 'body' and secured therein by the use ofa 'locking sleeve' which is spring biased towards the securing position. See further detailed presentation
The new design utilizes a bolt which includes resilient 'Wiglets' which biases the bolt towards engagement with the moveable member.
