ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The subject invention relates to a motion transmitting remote control assembly of the type for transmitting motion in a curved path by a flexible motion transmitting core element movably supported in a conduit and, more specifically, to such an assembly including a swivel tube attached to the end of the conduit for slidably supporting a rod attached to the end of the core element.
2. Description of the Prior Art
Such assemblies are well known in the prior art and many have been developed by the assignee of the subject invention as exemplified by U.S. Pat. No. 3,429,197 to Loewenstem. However, such assemblies are fabricated by separate steps for the support fitting, which supports the conduit on a structure. Alternatively, the swivel tube is supported in a female socket in the support fitting, a relatively complex fabrication process, as illustrated in U.S. Pat. No. 4,333,361 to Spease.
SUMMARY OF THE INVENTION AND ADVANTAGES
A method of fabricating a motion transmitting remote control assembly comprising a conduit movably supporting a core element and having first and second ends with a support fitting spaced from the first end of the conduit for supporting the conduit on a support structure, a swivel tube attached to the first end of the conduit in spaced relationship to the support fitting and a rod attached to the core element and movably supported in the swivel tube. The method is characterized by simultaneously molding the support fitting and the swivel tube of an organic polymeric material in bonded relationship to the conduit.
In the resulting assembly, the support fitting and the swivel tube consist of an organic polymeric material bonded to the conduit. This new assembly eliminates the complex process of assembling a swivel tube in a socket in the support fitting and utilizes the conduit as the swivel joint.
