Abstract
A rotating assembly and a movable puzzle platform using the same are disclosed in present invention. The movable puzzle platform includes a board assembly having a puzzle board, a kickstand pivotally coupled at the board assembly and the rotating assembly attached on the kickstand and having a first moving member, a second moving member rotatably coupled to the first moving member for forming a holding space and a plurality of ball bearings rotatably received in the holding space for allowing the second moving member rotating with respect to the first moving member. One end of the kickstand is pivotally coupled at the board assembly while a free end of the kickstand is adapted to pivotally fold from the board assembly.
Claims23
A rotating assembly comprising:
- a first moving member;
- a second moving member rotatably coupled to the first moving member for forming a holding space;
- and
- a plurality of ball bearings rotatably received in the holding space for allowing the second moving member rotating with respect to the first moving member;
- wherein the first moving member comprises a first middle portion, an inclining portion extending downwardly from the periphery of the middle portion, a first projecting portion extending upwardly from the periphery of the inclining portion, and an edge portion extending from the periphery of the first projecting portion and away from the first middle portion;
- and
- wherein the first middle portion is farther away from the ball bearings than an upper surface of the first projecting portion in a thickness direction of the rotating assembly.
A movable puzzle platform for placing a plurality of puzzle pieces thereon, comprising:
- a board assembly comprising a puzzle board;
- a kickstand pivotally coupled at the board assembly;
- and
- a rotating assembly attached on the kickstand and comprising a first moving member, a second moving member rotatably coupled to the first moving member for forming a holding space and a plurality of ball bearings rotatably received in the holding space for allowing the second moving member rotating with respect to the first moving member;
- wherein one end of the kickstand is configured for being pivotally coupled at the board assembly while a free end of the kickstand is adapted to pivotally fold from the board assembly;
- and an outer diameter of the rotating assembly is smaller than a length of the kickstand.
A movable puzzle platform for placing a plurality of puzzle pieces thereon, comprising:
- a board assembly comprising a puzzle board and a supporting portion attached on a bottom surface of the puzzle board;
- a kickstand pivotally coupled at the board assembly;
- and
- a rotating assembly attached on the kickstand and comprising a first moving member, a second moving member rotatably coupled to the first moving member for forming a holding space and a plurality of ball bearings rotatably received in the holding space for allowing the second moving member rotating with respect to the first moving member;
- wherein one end of the kickstand is configured for being pivotally coupled at the board assembly while a free end of the kickstand is adapted to pivotally fold from the board assembly;
- and
- wherein the supporting portion comprises a first inner supporting wall attached on a bottom surface of the puzzle board and a second inner supporting wall attached on the bottom surface of the puzzle board and spaced apart from the first inner supporting wall for forming a supporting space together with the first inner supporting wall, the kickstand is received in the supporting space.
