Universal channel rod adjustable extension apparatus

Abstract

A channel rod extension that provides access to the flexible cord through an opening of the extension, thereby allowing a user to quickly customize a length of the flexible cord and, accordingly, to quickly customize a dimension of the flexible cord-based system. The channel rod extension system includes an elongated extension with a discontinuous outer wall, forming a channel within which a flexible cord is received. A retainer made of a material having a high coefficient of friction surmounts the elongated extension to secure the flexible cord in place. To extend a dimension of the flexible cord-based system, the flexible cord is stretched and retained in place via the retainer, thereby elongating a dimension of the flexible cord-based system.

What is claimed is: 
     
         1 . A channel rod extension system designed for use in combination with a flexible cord-based system, the channel rod extension system comprising:
 a channel rod extension having an elongated main body extending between a first end and a second end, the main body including a discontinuous outer surface defining a channel to an interior wall of the main body;   an elongated flexible cord removably secured to the main body, the flexible cord being received within the channel and extending from at least the first end to the second end of the main body;   a first end cap secured to the first end of the main body, the first end cap configured to surmount the first end of the main body to retain the flexible cord within the channel; and   a second end cap secured to the second end of the main body, the second end cap configured to surmount the second end of the main body to retain the flexible cord within the channel.   
     
     
         2 . The channel rod extension system of  claim 1 , further comprising a retainer slidably secured to the main body and disposed between the first end cap and the second end cap, the retainer including a continuous inner-facing wall defining an opening therebetween, the opening spanning an inner diameter greater than an outer diameter of the main body, such that the retainer is configured to retain the flexible cord within the channel. 
     
     
         3 . The channel rod extension system of  claim 2  wherein the retainer is made of a material having a coefficient of friction greater than a coefficient of friction of the main body. 
     
     
         4 . The channel rod extension system of  claim 2  wherein the retainer is configured to slidably translate along a longitudinal axis of the channel rod extension, such that the retainer is configured to adjust a length of the flexible cord by translating the second end cap in a longitudinal direction away from the first end cap. 
     
     
         5 . The channel rod extension system of  claim 1  wherein the channel extends from the first end to the second end of the main body along a longitudinal axis of the channel rod extension. 
     
     
         6 . The channel rod extension system of  claim 1  wherein a diameter of the flexible cord is smaller than a diameter of the channel. 
     
     
         7 . The channel rod extension system of  claim 1  wherein the flexible cord extends from the first end cap to the second end cap. 
     
     
         8 . The channel rod extension system of  claim 1  wherein the flexible cord is an elastic shock cord. 
     
     
         9 . The channel rod extension system of  claim 1  wherein the first end cap includes an outer terminal diameter greater than the outer diameter of the main body, such that the first end cap is configured to form an attachment point receivable within an anchor point of a watercraft vessel. 
     
     
         10 . The channel rod extension system of  claim 1  wherein the first end cap includes an inner diameter greater than the outer diameter of the main body, such that the first end cap surmounts and forms a press fit with the main body. 
     
     
         11 . The channel rod extension system of  claim 1  wherein the second end cap is a ferrule configured to indirectly secure the channel rod to a frame structure. 
     
     
         12 . The channel rod extension system of  claim 1  wherein the second end cap includes an inner diameter greater than the outer diameter of the main body, such that the second end cap surmounts and forms a press fit with the main body. 
     
     
         13 . A channel rod extension system configured to adjust a dimension of a frame structure, the channel rod extension system comprising:
 a channel rod extension having an elongated main body extending between a first end and a second end, the main body including a discontinuous outer surface defining a channel to an interior wall of the main body, the channel rod configured to attach to a frame structure;   an elongated flexible cord removably secured to the main body, the flexible cord having a diameter small than a diameter of the channel, such that the flexible cord is removably receivable within the channel and extends from at least the first end to the second end of the main body;   a first end cap secured to the first end of the main body, the first end cap configured to surmount the first end of the main body to retain the flexible cord within the channel; and   a second end cap secured to the second end of the main body, the second end cap configured to surmount the second end of the main body to retain the flexible cord within the channel,   wherein in a default configuration, the flexible cord includes a first length determined by a first distance between the first end cap and the second end cap, and   wherein in an elongated configuration, the flexible cord includes a second length greater than the first length, the second length determined by a second distance between the first end cap and the second end cap, the second distance being greater than the first distance.   
     
     
         14 . The channel rod extension system of  claim 13  further comprising:
 a retainer slidably secured to the main body and disposed between the first end and the second end, the retainer including a continuous inner-facing wall defining an opening therebetween, the opening spanning an inner diameter greater than an outer diameter of the main body, the retainer having a coefficient of friction greater than a coefficient of friction of the main body, such that the retainer is configured to retain the flexible cord within the channel, 
 wherein, due to the coefficient of friction of the retainer, the retainer maintains the flexible cord at the second length, thereby adjusting a dimension of the frame structure. 
 
     
     
         15 . The channel rod extension system of  claim 14  wherein the retainer is configured to slidably translate along a longitudinal axis of the channel rod extension, such that the retainer is configured to translate the second end cap between the first distance and the second distance with respect to the first end cap, thereby translating the flexible cord between the first length and the second length.
