Claim Text:
1. A rotating handle apparatus for a luggage case being disposed between two retractable rods of the handle of the luggage case, each of the retractable rods including a connecting tube, at one end of each of the connecting tubes being formed an assembling chamber, the handle-rotation apparatus comprising: an annular grip member disposed between the two connecting tubes and defining an annular space, the annular grip member including two assembling portions aligned to the two assembling chambers, and two inserting holes which are in communication with the annular space and located at the two assembling portions, the annular grip member further including a through hole in communication with the annular space; a control button disposed inside the annular grip member and including a button portion and two arms extending toward the two assembling portions from the button portion, the button portion being elastically inserted in the through hole of the annular grip member; two rotation mechanisms disposed between the assembling portions of the annular grip member and the assembling chambers of the two connecting tubes, respectively, and being rotated by the control button to adjust an angle of the annular grip member with respect to the connecting tubes; wherein each of the rotation mechanisms comprises: an engaging member which is disposed in the annular space and engaged in a corresponding one of the inserting holes, and includes a multi-stepped hole which consists of a first circular hole, a middle ratchet hole and a second circular hole with a smaller diameter than the first circular hole; a base which is fixed in a corresponding one of the assembling chambers of the connecting tubes, each of the assembling portions of the annular grip members and a corresponding one of the assembling chambers of the connecting tubes are rotatable with each other and pivotally connected by the base, the base is provided with a ratchet hole formed in the shape of the ratchet hole of the engaging member, a circular hole and a polygonal hole; a control shaft which is elastically disposed between the engaging member and the base and able to move back and forth repeatedly, the control shaft includes a cylindrical section inserted in the second circular hole of the engaging member, a ratchet section engaged in the ratchet hole of the engaging member and the base, and a polygonal section which is formed in the shape of the polygonal hole and inserted through the ratchet hole and the circular hole of the base and into the polygonal hole; a driven member which is pivotally disposed in the annular space of the annular grip member, and includes a driven portion abutted against a corresponding one of the arms of the control button, and a drive portion abutted against one end of the cylindrical section of the control shaft; wherein a locking pin is formed in each of the assembling chambers; the inserting holes of the annular grip member are circular-shaped; each of the bases includes a seat portion in the form of a circular pillar, and the ratchet hole, the circular hole and the polygonal hole are formed in the seat portion, on an outer surface of each of the bases is formed an annular groove which is located between the ratchet hole and the circular hole and provided for engaging with a peripheral edge of a corresponding one of the inserting holes of the annular grip member, on two opposite sides of the outer surface of each of the bases are provided a restricting portion which is to be fixed to a top edge of each of the assembling chambers of the connecting tubes and located corresponding to the circular hole and the polygonal hole, and a positioning portion which is fixed to the locking pin of a corresponding one of the connecting tubes by a fastener; pressing the control button can cause movement of the driven member and the control shafts which are disposed between the annular grip member and the connecting tubes, in such a manner that the arms push the driven member, then the driven member push the control shaft to move between the engaging member and the base.
