Abstract:
A jigsaw puzzle without a frame, comprising a jigsaw puzzle body which comprises an outer jigsaw puzzle piece unit (10) and a plurality of inner jigsaw puzzle pieces (40); the outer jigsaw puzzle piece unit (10) comprises at least one outer jigsaw puzzle piece, the outer jigsaw puzzle pieces each comprising a body (21, 31) and at least one side wall piece (22, 32); the periphery of the top face of the body (21, 31) forms an outer tessellation portion (216, 314); the side wall piece (22, 32) is rotatably connected to the periphery of the top face of the body (21, 31); the side wall piece (22, 32) can be rotated such that the outer wall face is parallel to the top face of the body and can be rotated such that the inner wall face is combined with the side face of the body (21, 31); the outer jigsaw puzzle piece unit (10) has an annular shape and encloses an inner space; the inner jigsaw puzzle pieces (40) are provided in the inner space of the outer jigsaw puzzle piece unit (10), each of the inner jigsaw puzzle pieces (40) is provided with an inner tessellation portion (41), the inner jigsaw puzzle pieces (40) are fitted together by means of the inner tessellation portions (41), and some of the inner jigsaw puzzle pieces (40) and the outer jigsaw puzzle piece unit (10) are fitted together by means of the inner tessellation portions (41) and the outer tessellation portions (216, 314); the top face of the body (21, 31) of the outer jigsaw puzzle piece, the outer wall face of the side wall piece (22, 32) of the outer jigsaw puzzle piece, and the top faces of the inner jigsaw puzzle pieces (40) are provided with patterns. The patterns of the top face and the side face of the outer jigsaw puzzle piece of said jigsaw puzzle without a frame can be printed at the same time, so that the discontinuity of the patterns on these two positions can be effectively and easily avoided, thereby achieving the goal of facilitating manufacture.
