Abstract
A rotating device and a jigsaw puzzle table using the rotating device are disclosed in present disclosure. The jigsaw puzzle board includes a board assembly having a body portion and a kickstand coupled with the body portion, and at least one rotating device attached to the kickstand of the board assembly. When the kickstand is in a folded state, at least a part of the rotating device protrudes from a lower surface of the board assembly and contacted with a playing surface. The board assembly is capable of being rotated on the playing place via the rotating device. When the kickstand is in the unfolded state, the body portion and the rotating device are inclined and supported on the playing surface.
Claims23
A rotating device for moving on a playing surface, comprising:
- a case comprising a receiving space and an opening formed on the case and communicated with the receiving space;
- a first roller received in the receiving space;
- and
- a second roller completely received in the receiving space and in contact with the first roller to rotate together with the first roller;
- wherein when the first roller and the second roller rotate, at least a part of the first roller passes through the opening to make contact with the playing surface;
- wherein the second roller is blocked by the first roller in the receiving space for preventing the second roller from leaking out of the opening;
- wherein a radius of the first roller is greater than a radius of the second roller;
- and
- wherein the case comprises an engaging wall and a side wall extending from the engaging wall;
- the second roller abuts against both the engaging wall and the side wall;
- the first roller is spaced apart from the engaging wall, and wherein the case comprises a main portion, a fixing portion extending from the main portion and a dome covering on the main portion and connected to the fixing portion;
- the engaging wall is formed on the main portion;
- and the opening passes through the dome.
