Abstract: A clothing hanger assembly includes an upper loop track and a lower loop track and a rack connected therebetween for supporting the upper loop track and the lower loop track. A plurality of hanger units are slidably coupled between the upper loop track and the lower loop track and linked to each other, thereby having a synchronous revolution along the upper loop track and the lower loop track when operated by a user. Each hanger unit includes an upper sliding device and a lower sliding device and a clothing hanger frame rotatably coupled therebetween, such that the upper sliding device and the lower sliding device are used to execute the synchronous revolution along the tracks while the frame can have a free rotation about an axis therethrough when operated by the user.

Abstract: This invention relates to an improved structure for tee joint comprising a first tube provided at one end with a saddle shaped recess. A second tube is furnished at its periphery with a pair of aligned holes and can be disposed on the recess of the first tube. A housing provided at its center with tapered recess is received in and secured to the interior of the first tube near the recess thereof. A tapered plug is received in and secured to the tapered recess of the housing. A threaded member is passed through the aligned holes of the second tube and engaged with the tapered plug received in the first tube to make the second tube fixedly secured to the first tube.
