US 4,348,348 A · Method for making a remote control assembly with vibration dampener

Abstract

Method for making a motion transmitting remote control assembly of the type for transmitting motion in a curved path by a flexible motion transmitting core element including a flexible motion transmitting core element and a flexible conduit. An end fitting is disposed about the end portion of the conduit for supporting the conduit and core element with the core element extending from the end fitting. The assembly also includes a support housing for supporting the end fitting and the conduit on a support structure. The assembly is characterized by a resilient vibration dampener disposed between the support housing and the end fitting for providing noise and vibration isolation therebetween. A mold assembly and a method are also disclosed for making the motion transmitting remote control assembly including the steps of; inserting the end portion of the conduit into a cavity of a first mold and injecting organic polymeric material into the cavity for molding the end fitting about the conduit, inserting the end fitting into a cavity of a second mold and injecting a vibration dampening material into the mold for molding a vibration dampener about the end fitting, and placing the vibration dampener into a cavity of a third mold and injecting an organic polymeric material for molding a support housing about the vibration dampener.

Dependent claims

A method for making a motion transmitting remote control assembly (10) of the type for supporting a flexible motion transmitting core element (12) including the steps of:

inserting the end portion of a conduit (14) into a cavity (72) of a first mold (74) and injecting a hardenable organic polymer into the cavity for molding an end fitting (16) about the conduit (14);
inserting the end fitting (16) into a cavity (82) of a second mold (84) and injecting a hardenable vibration dampening material into the cavity of the second mold to mold the vibration dampening material about the end fitting (16) and the end portion of the conduit (14) to define a vibration dampener (24) including an extending section (26);
placing the conduit (14) with the vibration dampener (24) in a third mold (90) having a third cavity (88), the extending section (26) engaging the third mold (90) and the remaining portion of the vibration dampener (24) being spaced from the third mold (90) defining the third cavity (88);
injecting a hardenable organic polymer into the third cavity (88) about the vibration dampener (24) to form a support member (22) spaced from and isolated from said end fitting (16) by the vibration dampener;
and allowing the materials of the end fitting (16), vibration dampener (24) and support member (22) to harden so that the vibration dampener (24) is softer than the end fitting (16) or the support member (22).

A method for making a motion transmitting remote control assembly (10) of the type including a guide means and a male swivel portion (44) having a convex spherical surface for supporting a flexible motion transmitting core element (12) including the steps of;

disposing a vibration dampening material about the guide means to define a vibration dampener (24) including an extending section (26) and disposing an organic polymeric support member (22) about the vibration dampener (24) so that the extending section (26) extends through the support member (22) to isolate the guide means from the support member (22) and about the male swivel portion (44) to form a female swivel portion (46) having a partially concave spherical surface in mating engagement with the convex spherical surface of the male swivel portion (44).
