Abstract
A telescoping tube assembly includes a frame and a first longitudinal tube section mounted on the frame. A second longitudinal tube section is disposed within the first longitudinal tube section and adapted for telescoping motion into and out of the first longitudinal tube section. The telescoping tube assembly includes a cabling system that includes a top pulley assembly and a bottom pulley assembly, the bottom pulley assembly adapted for movement in response to the telescoping motion of the second longitudinal tube section. One or more cables extend from the remote end of the innermost longitudinal tube section and traverse the top pulley assembly, the bottom pulley assembly and are fixed relative to the frame.
Claims22
A telescoping tube assembly comprising:
- a frame;
- a first longitudinal tube section mounted on the frame;
- an innermost longitudinal tube section disposed within the first longitudinal tube section and adapted for telescoping motion into and out of the first longitudinal tube section, wherein the innermost longitudinal tube section comprises a remote end;
- a cabling system comprising a top pulley assembly and a bottom pulley assembly, the bottom pulley assembly adapted for movement relative to the top pulley assembly and in response to the telescoping motion of the innermost longitudinal tube section wherein the top pulley assembly is stationary relative to the first longitudinal tube section;
- one or more cables extending within the telescoping tube sections from the remote end of the innermost longitudinal tube section and traversing the top pulley assembly and the bottom pulley assembly, wherein the top pulley assembly is traversed before the bottom pulley assembly, the one or more cables being fixed relative to the frame.
A telescoping assembly comprising:
- a frame;
- a plurality of nested longitudinal tube sections comprising an outermost longitudinal tube section and an innermost longitudinal tube section having a remote end, wherein the outermost longitudinal tube section is fixed relative to the frame;
- a cabling system comprising a top pulley assembly having a top pulley and a bottom pulley assembly having a bottom pulley, the bottom pulley assembly adapted for movement relative to the top pulley assembly and in response to the telescoping motion of the innermost longitudinal tube section wherein the top pulley assembly is stationary relative to the outermost longitudinal tube section;
- one or more cables extending within the plurality of nested longitudinal tube sections from the remote end of the innermost longitudinal tube section and traversing the top pulley assembly and the bottom pulley assembly, wherein the top pulley assembly is traversed before the bottom pulley assembly for each cable, the one or more cables being fixed relative to the frame;
- and
- a linear guide attached to the frame and constrained to provide linear motion to the bottom pulley assembly in response to the telescoping motion of the longitudinal tube sections.
