Abstract
Abstract An improved mounting is provided for bearings facilitating movement between two adjacent concentric tubes of a telescoping tube system. Within the interior wall of the outer of the two adjacent tubes there is located a socket having a shelf within. A bearing is mounted on a mounting piece which has a shoulder. With the mounting piece inserted into the socket the shoulder lodges against and rests upon the shelf so that the position of the bearing is maintained when force is applied to it by the inner tube of the two adjacent tubes.

Independent Claim
329 words
In an assembly of telescoping tubes including at least a hollow outer tube with an inner tube positioned within and capable of translation through the hollow outer tube, the outer tube having an opening extending radially from the inner wall of the outer tube, and a bearing mounted in a mounting structure positioned on the outer tube in rotatable contact with said inner tube, said mounting structure for the bearing comprising; a shelf in the form of a portion of the inner wall of the outer tube extending outwardly from the perimeter of the opening recessed from surrounding portions of the inner wall, and a mounting piece for holding and positioning the bearing, said mounting piece having a first end from which said bearing protrudes and a second end on the opposite side of said mounting piece from said first end, said second end being of cross sectional configuration capable of being inserted into the opening and having a shoulder in the form of a solid projection extending outwardly from the body of said mounting piece between said first end and said second end, the cross section of said mounting piece through said shoulder being of such shape that with said second end of said mounting piece positioned within said opening said cross section of said mounting piece through said shoulder extends beyond the opening at the inner wall and is encompassed within said recess and said shoulder is in contact with said shelf so that with said mounting piece positioned within the opening said bearing is in rotatable contact with the exterior surface of the inner tube and forces exerted by the inner tube against the bearing act to displace said mounting piece radially from and axially to the inner tube, said shelf in contact with said shoulder and said second end positioned within said opening acting to oppose said displacement, thereby maintaining the bearing in position within the opening and in rotatable contact with the inner tube.

In an assembly of telescoping tubes including at least a hollow outer tube with an inner tube positioned within and capable of translation through the hollow outer tube, the outer tube having an opening extending radially from the inner wall of the outer tube, and a bearing mounted in a mounting structure positioned on the outer tube in rotatable contact with said inner tube, said mounting structure for the bearing comprising; a shelf in the form of a portion of the inner wall of the outer tube extending outwardly from the perimeter of the opening recessed from surrounding portions of the inner wall, and a mounting piece for holding and positioning the bearing, said mounting piece having a first end from which said bearing protrudes and a second end on the opposite side of said mounting piece from said first end, said second end being of cross sectional configuration capable of being inserted into the opening and having a shoulder in the form of a solid projection extending outwardly from the body of said mounting piece between said first end and said second end, the cross section of said mounting piece through said shoulder being of such shape that with said second end of said mounting piece positioned within said opening said cross section of said mounting piece through said shoulder extends beyond the opening at the inner wall and is encompassed within said recess and said shoulder is in contact with said shelf so that with said mounting piece positioned within the opening said bearing is in rotatable contact with the exterior surface of the inner tube and forces exerted by the inner tube against the bearing act to displace said mounting piece radially from and axially to the inner tube, said shelf in contact with said shoulder and said second end positioned within said opening acting to oppose said displacement, thereby maintaining the bearing in position within the opening and in rotatable contact with the inner tube.

In an assembly of telescoping tubes including at least a hollow outer tube with an inner tube positioned within and capable of translation through the hollow outer tube, the outer tube having an opening extending radially from the inner wall of the outer tube, and a bearing mounted in a mounting structure positioned on the outer tube in rotatable contact with said inner tube, said mounting structure for the bearing comprising; a shelf in the form of a portion of the inner wall of the outer tube extending outwardly from the perimeter of the opening recessed from surrounding portions of the inner wall, and a mounting piece for holding and positioning the bearing, said mounting piece having a first end from which said bearing protrudes and a second end on the opposite side of said mounting piece from said first end, said second end being of cross sectional configuration capable of being inserted into the opening and having a shoulder in the form of a solid projection extending outwardly from the body of said mounting piece between said first end and said second end, the cross section of said mounting piece through said shoulder being of such shape that with said second end of said mounting piece positioned within said opening said cross section of said mounting piece through said shoulder extends beyond the opening at the inner wall and is encompassed within said recess and said shoulder is in contact with said shelf so that with said mounting piece positioned within the opening said bearing is in rotatable contact with the exterior surface of the inner tube and forces exerted by the inner tube against the bearing act to displace said mounting piece radially from and axially to the inner tube, said shelf in contact with said shoulder and said second end positioned within said opening acting to oppose said displacement, thereby maintaining the bearing in position within the opening and in rotatable contact with the inner tube.
