US 4,375,771 A · Resilient control link assembly

Abstract

A resilient control link assembly for a control system for transmitting a mechanical signal from a transmitter to a receiver so as to prevent component damage resulting from force overload situations due to response differences of components, fluid pressure failure, etc. The assembly includes two link elements which cooperate with the receiver and transmitter and are hinged together at a main hinge for relative swinging thereabouts from a datum relationship. Two following members are hinged to the first link element for rotation about a follower hinge spaced from the main hinge and are adapted to contact the second link element. A resilient member interconnects the two following members to force the members to cooperate with the second link element to maintain the link element in the datum relationship. When the datum relationship is disturbed, the following members are moved apart and the resilient means opposes this movement tending to draw the link elements back into the datum relationship.

Dependent claims

A resilient control link assembly cooperating with a fulcrum means and being adapted to transmit a mechanical signal from a transmitter to a receiver, the control link assembly having:

(a) first and second link elements hinged together at a main hinge for swinging thereabouts relative to each other and adapted to be disposed relative to each other in a datum relationship;
the transmitter and the receiver each cooperating with at least one of the link elements,
(b) a pair of following members, each following member being hinged to the first link element for rotation about a follower hinge spaced from the main hinge, and each following member also having a first contact portion disposed on a side of the main hinge remote from the follower hinge, so that at least one particular contact portion is adapted to contact the second link element,
(c) resilient means interconnecting the two following members to force at least the particular contact portion into engagement with the second link element so as to maintain the link elements in the datum relationship,
so that when there is relative angular movement between the link elements to disturb the datum relationship therebetween, the following members are moved apart and the resilient means opposes this movement and forces the particular contact portion against the second link element, thus tending to draw the link elements back into the datum relationship.

(b) a pair of following members, each following member being hinged to the first link element for rotation about a follower hinge spaced from the main hinge, and each following member also having first and second contact portions spaced at different spacings from the follower hinge and adapted to contact the second link element,
(c) resilient means interconnecting the two following members to force the members to cooperate with one of the link elements to maintain the link elements in the datum relationship,
so that when there is relative angular movement between the link elements to disturb the datum relationship therebetween, the following members are moved apart and the resilient means opposes this movement, tending to draw the link elements back into the datum relationship.
