Abstract
A telescoping joint assembly and a method for making a telescope joint assembly 10. The joint assembly 10 has a pair of members 12, 14 which are telescopically engaged. Assembly 10 further includes a resinous, plastic and/or polymer material 16 which shrinkably coats or lines the inner shaft 12 after the inner shaft 12 is heated and exposed to a substantially inert gas, thereby providing a relatively durable and substantially “low friction” bearing or surface 18 which is effective to promote and/or assist the telescopic sliding motion between the members 12, 14.
Claims10
A method for manufacturing a telescoping joint assembly, said method comprising the steps of:
- providing a first member having a cavity of a first shape;
- injecting an amount of inert gas into said cavity which is only sufficient to substantially fill said cavity;
- providing a second member;
- heating said first member;
- placing an amount of liquefied thermosetting material within said cavity;
- heating said second member;
- inserting said heated second member within said cavity to cause said liquefied thermosetting material to be distributed within said cavity and around said second member;
- and
- cooling said first member effective to solidify said material and to shrink said material, thereby bonding said material onto said second member.
A method for manufacturing a telescoping joint assembly, said method comprising the steps of:
- providing a first member having an oblong cavity;
- providing a second member having a shape corresponding to said oblong cavity;
- injecting an amount of inert gas into said oblong cavity which is only sufficient to substantially fill said oblong cavity;
- heating said first member;
- placing an amount of liquefied thermosetting material within said cavity;
- heating said second member;
- inserting said heated second member within said cavity to cause said liquefied thermosetting material to distributed within said cavity and around said second member;
- and
- cooling said first ember effective to solidify said material and to shrink said material, thereby bonding said material onto said second member.
