Abstract
A system and process for removably and replaceably coupling two hollow carbon fiber composite structures without the need for adhesives or welding. A universal coupling makes use of reciprocating catches in the end regions of the universal coupling. The reciprocating catches engage receiving features provided in the hollow carbon fiber composite structures to couple the hollow carbon fiber composite structures to the universal coupling, and through the universal coupling, couple the hollow carbon fiber composite structures together. The hollow carbon fiber composite structures can be uncoupled by disengaging the reciprocating catches of the universal coupling from the receiving features of the hollow carbon fiber composite structures.
Claims17
A universal coupling system for removably and replaceably coupling hollow carbon fiber composite structures, the universal coupling system comprising:
- a first hollow carbon fiber composite structure having at least one first receiving feature;
- a second hollow carbon fiber composite structure having at least one second receiving feature;
- and
- a universal coupling comprising:
- a body having a first mating end region having a first mating end, a second mating end region having a second mating end that are at an opposite end of the body from the first mating end region and the first mating end, and at least one body sidewall spanning therebetween and structurally connecting the first mating end region and first mating end with the second mating end region and second mating end;
- at least one first mating end catch disposed in the at least one body sidewall at the first mating end region, and which reciprocates by extending outward from the body to an engaged position and retracting inward to the body to a dis-engaged position;
- and
- at least one second mating end catch disposed in the at least one body sidewall at the second mating end region, and which reciprocates by extending outward from the body to an engaged position and retracting inward to the body to a dis-engaged position;
- wherein the at least one first mating end catch is structurally sized and positioned in such a way that engages the at least one first receiving feature of the first hollow carbon fiber composite structure when the first mating end is placed in a predetermined coupled position and orientation inside the first hollow carbon fiber composite structure with the at least one first mating end catch in the engaged position into the at least one first receiving feature;
- wherein the at least one second mating end catch is structurally sized and positioned in such a way that engages the at least one second receiving feature of the second hollow carbon fiber composite structure when the second mating end is placed in a predetermined coupled position and orientation inside the second hollow carbon fiber composite structure with the at least one second mating end catch in the engaged position into the at least one second receiving feature;
- wherein the universal coupling is removable and replaceable and fixedly couples the first hollow carbon fiber composite structure with the second hollow carbon fiber composite structure without requiring adhesive or welding;
- wherein at least one of the first mating end catch and second mating end catch comprises:
- a recess in the sidewall of the first mating end region or second mating end region;
- and
- a spring-loaded reciprocatable pin, disposed within the recess, that is part of an assembly secured in the recess using one or more fasteners allowing the at least one of the first mating end catch and second mating end catch to be swapped out or replaced as necessary for a particular application.

- wherein the at least one first mating end catch is structurally sized and positioned in such a way that engages the at least one first receiving feature of the first hollow carbon fiber composite structure when the first mating end is placed in a predetermined coupled position and orientation inside the first hollow carbon fiber composite structure with the at least one first mating end catch in the engaged position into the at least one first receiving feature;
- and
- wherein the at least one second mating end catch is structurally sized and positioned in such a way that engages the at least one second receiving feature of the second hollow carbon fiber composite structure when the second mating end is placed in a predetermined coupled position and orientation inside the second hollow carbon fiber composite structure with the at least one second mating end catch in the engaged position into the at least one second receiving feature;
- wherein at least one of the first mating end catch and second mating end catch comprises:
- a recess in the sidewall of the first mating end region or second mating end region;
- and
- a spring-loaded reciprocatable pin, disposed within the recess, that is part of an assembly secured in the recess using one or more fasteners allowing the at least one of the first mating end catch and second mating end catch to be swapped out or replaced as necessary for a particular application;
- placing the first mating end inside the first hollow carbon fiber composite structure and engaging the at least one first receiving feature of the first hollow carbon fiber composite structure with the at least one first mating end catch of the first mating end region;
- and
- placing the second mating end inside the second hollow carbon fiber composite and structure engaging the at least one second receiving feature of the second hollow carbon fiber composite structure with the at least one second mating end catch of the second mating end region, resulting in the removable and replaceable coupling of the first hollow carbon fiber composite structure with the second hollow carbon fiber composite structure without requiring adhesive or welding.
