Abstract:
An adjusting device for control cable (3) terminals (2), composed of a sheathed steel cable (4, 5), which terminals (2) have a main body (11) provided with means of linkage (19) to a control actuating device (8) or to its associated mechanism (9), the adjusting device including:on the main body (11), a longitudinal housing (12) open at one of its ends, the rear end (13, 14);a regulating rod (22) arranged in the longitudinal housing (12) of the main body (11), through which the rod can slide in both directions (A, B), which rod (22) projects permanently from the main body (11) by one of its ends, the exterior end (43), attached to the corresponding end of the steel cable (4) of the control cable (3), while the other end, the interior end (41), has a threaded retaining portion (42);a thrust spring (23) coaxially arranged with respect to the regulating rod (22), which spring works permanently under compression with one of its ends (63) resting against the interior end (41) of the regulating rod (22) and its other end (65) against the main body (11), in such a way that the regulating rod (22) is permanently subjected to a force directed from the outside inwards; andfixing means which fix the position of the regulating rod (22) with respect to the main body (11), characterized in that the fixing means include:two retaining bodies (20) arranged in the longitudinal housing (12) of the main body (11), facing each other and oriented transversally with respect to the regulating rod (22) which runs between them, which retaining bodies (20) have respective threaded retaining portions (26) which coincide with the threaded portion of the regulating rod (22) and can slide transversally between two positions, one position in which the threaded retaining portions (26, 42) of the retaining bodies (20) and of the regulating rod (22) mesh with each other and secure the position of the rod (22) with respect to the main body (11), and an out-of-mesh position of said threaded portions (26, 42) in which the regulating rod (22) can slide in both directions;two retaining springs (21) arranged between the two retaining bodies (20), one on either side of the regulating rod (22), which work permanently under compression with each of their two ends resting against a respective retaining body (20), in such a way that they tend permanently to situate the retaining bodies (20) in the out-of-mesh position;a fixing body (24) fitted onto the open end (13, 14) of the longitudinal housing (12) of the main body (11) and provided with a through-orifice (46) through which the regulating rod (22) can slide in both directions, which fixing body (24) includes two fixing extensions (48, 61) arranged between the retaining (20) and main (11) bodies and able to slide in both directions between two extreme positions, exterior and interior, respectively;on the retaining bodies (20) and on the fixing extensions (48, 61) of the fixing body (24), respective and complementary meshing means which, when the fixing body (24) is in the exterior position, permit the action of the retaining springs (21) to move the retaining bodies (20) into the out-of-mesh position, whereas when the fixing body (24) is in the interior position the retaining bodies (20) take up the meshed position by submitting the retaining springs (21) to greater compression due to reduction of their length.
