Abstract
The Rotating Device (1) comprises a rotating shaft (1000) being bearing interrelated to a nipple/coupling frame. The rotating shaft (1000) supports swing arms right and left from which are suspended swing seats. The nipple/coupling frame extends into and is supported by a generally concrete foundation.
Claims7
A Rotating Device (1) comprising:
- a. a cylindrical rotating shaft (1000);
- an upper sleeve (1100) slidably received by the rotating shaft (1000);
- a lower sleeve (1170) slidably received by the rotating shaft (1000) distal to the upper sleeve (1100);
- the upper sleeve (1100) and the lower sleeve (1170) are rigidly and immovably affixed to the rotating shaft (1000) generally by welding;
- b. an upper bearing assembly (1130) is slidably received by the rotating shaft (1000), is intermediate the upper sleeve (1100) and the lower sleeve (1170) and is proximal to the upper sleeve (1100) and is distal to the lower sleeve (1170);
- c. a lower bearing assembly (1160) is slidably received by the rotating shaft (1000), is intermediate the upper sleeve (1100) and the lower sleeve (1170) and is proximal to the lower sleeve (1170) and is distal to the upper sleeve (1100);
- d. a nipple/coupling frame (1050) rotatably supports the upper bearing assembly (1130) and the lower bearing assembly (1160) allowing the rotating shaft (1000) to rotate relative to the nipple/coupling frame (1050);
- the nipple/coupling frame (1050) extending downwardly for vertical anchoring of the Rotating Device (1) in a generally concrete support base (1189).
