Field of the Invention
This invention relates to a rotatable clothing hanger assembly, especially to one which has a plurality of hanger units which can revolve synchronously along two parallel loop tracks with each hanger unit being able to rotate freely about an axis therethrough.
Background of the Invention
Rotatable clothing hanger assemblies used at the present time, are typified by such a patent example as U.S. Pat. No. 5,062,536, which discloses a rotatable hanger assembly having a plurality of hanger units pivotally and slidably coupled together between an upper track and a lower track, such that all hanger units are moved in concert along the tracks and clothing hung thereon can be reached easily. However, there is still one drawback of the previous hanger, in that, each hanger unit is not permitted &.o rotate about an inner axis, thus occupying a lot of space in the whole hanger assembly.
Summary of the Invention
The primary objective of the present invention is to provide a rotatable clothing hanger assembly including a plurality of hanger units for hanging clothes thereon, each of which can be rotated independently and together can be moved synchronously along two parallel loop tracks for easily handling the clothes hung thereon.
In accordance with one aspect of the invention, a clothing hanger assembly which includes an upper loop track and an identically shaped lower loop track is provided. The two tracks are supported by a rack such that the upper track is parallel to the lower track. A plurality of hanger units are slidably coupled between the upper track and the lower track and linked to each other by an upper linking bar and a lower linking bar such that the hanger units can move in concert along the tracks when operated by a user. Each hanger unit includes an upper sliding means and a lower sliding means with a clothing hanger frame rotatably connected therebetween, such that the hanger units can revolve along the tracks when a user operates the upper/lower sliding means, and any of the clothing hanger frames can rotate freely about an axis therethrough when the user operates on a specific clothing hanger frame.
These and additional objects, if not set forth specifically herein, will be readily apparent to those skilled in the art from the detailed description provided hereunder, with appropriate reference to the accompanying drawings.

Detailed Description of the Preferred Embodiments
Referring to FIG. 1, a rotatable clothing hanger assembly comprises a rack having an upper rack frame 15, a lower rack frame 10 and a pair of spaced posts 12 connected therebetween. The upper rack frame 15 and the lower rack frame 10 are similarly formed as horizontal H-shaped structures, both of which are parallel to each other, and each of the spaced posts 12 is engaged between two interaction points of the H-shaped structure of the upper and the lower rack frames. An upper loop track 14 is mounted on the upper rack 15 and supported thereby. A lower loop track 13 having the same shape as the upper loop track 14 is mounted on the lower rack frame 10 and supported thereby, such that both tracks 13 and 14 are fixed on the rack and are parallel to each other.
A plurality of hanger units 2 are slidably mounted between the upper track 14 and the lower track 13 and linked to each other, thereby permitting each hanger unit to rotate in concert with each other along the upper track 14 and the lower track 13 when operated by a user. Each hanger unit 2 also has a free rotation about an axis therethrough when operated by the user, which is to be described later.
Referring to FIGS. 2 to 4, the hanger unit 2 is described in more detail. Each hanger unit 2 comprises an upper sliding means 4, a lower sliding means 3, and a clothing hanger frame 20 rotatably coupled therebetween. The upper sliding means 4 includes an upper rod 31 which is horizontally positioned under the upper track 14 and a pair of upper clamping means 70, each of which has a first end connected to each end of the upper rod 31 and a second end slidably hanging on the upper track 14. The lower sliding means 4 includes a lower rod 30 which is horizontally positioned above the lower track 13 and a pair of lower clamping means 50 each of which has a first end connected to each end of the lower rod 30 and a second end slidably positioned on the lower track 13. The clothing hanger frame 20 is rotatably coupled between the upper rod 31 and the lower rod 30 and has a first bar 24 mounted across an upper portion thereof and a second bar 21 mounted across a middle portion thereof for hanging clothing.
An upper linking bar 41 and a lower linking bar 40 are connected between two adjacent hanger units 2, such that all the hanger units 2 can be moved in concert along the upper track 14 and the lower track 13. The upper linking bar 41 has two ends, each of which is engaged between an upper clamping means 70 and a corresponding upper rod 31. The lower linking bar 40 has two ends, each of which is engaged between a lower clamping means 50 and a corresponding lower rod 30.
Referring to FIGS. 2 and 5, the upper clamping means 70 comprises a U-shaped fork 73 which encloses a longitudinal section of the upper track 14 and two upper rollers 71 which are mounted at each prong of the fork 73 for contacting with and sliding along the upper track 14. The upper clamping means 70 further comprises an inverse U-shaped support plate 72 attached to two inner walls of the U-shaped fork 73 under the upper track 14 for strengthening the inner walls of the U-shaped fork 73.
Referring to FIGS. 2 and 6, the lower clamping means 50 comprises an inverse U-shaped fork 52 which encloses a longitudinal section of the lower track 13 and two lower rollers 51 mounted at each prong of the inverse U-shaped fork 52 for contacting with and sliding along the lower track 13.
Referring to FIGS. 5 and 6, an upper bearing means 8 is pivotally coupled between the upper rod 31 and an upper side of the clothing hanger frame 20 and a lower bearing means 8' pivotally coupled between the lower rod 30 and a lower side of the clothing hanger frame 20 such that the clothing hanger frame 20 can make a free rotation about an axis therethrough when it is manipulated by a user.
FIG. 7 illustrates the relationship of the upper bearing means 8 rotatably coupled between the upper rod 31 and the upper side of the clothing hanger frame 20. The relationship between the lower side cf the clothing hanger frame 20 and the lower rod 30 is the same. The upper bearing means 8 and the lower bearing means 8' are identically constructed.
Referring to FIG. 8, the upper bearing means 8 (also the lower bearing means 8') comprises an upper housing 80, a lower housing 82 which is complementary to the upper housing 80, and a ring bearing 81 received therebetween to allow the upper housing 80 to rotate with respect to the lower housing 82. The structure of the ring bearing 81 can be seen more clearly refers to FIG. 7. The ring bearing 81 comprises a ball retainer 811 and eight balls 810 being rotatable in the ball retainer 811. The ball retainer 811 is shaped as a ring shell with eight holes at a top surface thereof, an inner wall and an outer wall extending from the top surface and slanting downward thereby holding the balls 810. The upper housing 80 has an upper recess 801 for receiving/holding a longitudinal section of the upper rod 31. The lower housing 82 has a lower recess 821 for receiving/holding a longitudinal section of the upper side of the clothing hanger frame 20. An upper hole 802 is formed in the center of the upper housing 80 and a lower hole 822 is also formed in the center of the lower housing 82, such that both holes 802 and 822 are in alignment with each other. A bolt 63 is installed through the upper hole 802 and the lower hole 822 to secure the upper housing 80 to the upper rod 31 and the lower housing 82 to the upper side of the clothing hanger frame 20 by cooperating with a nut 65, such that the clothing hanger frame 20 can rotate relative to the upper rod 31 and the lower rod 30 when manipulated by a user.
