The present invention will be better understood by referring to the accompanying drawings, wherein:
Referring to
The base plate 1 is made of plastic, and pervious to light. The base plate 1 has a protruding border 11, an image layer 12 sandwiched in the protruding border 11, and a transparent middle portion 14 encompassed by the protruding border 11. The protruding border 11 has fitting portions 13, which are provided for connection with the pieces 2, and which can be fitting protrusions 131 or fitting gaps 132. The middle portion 14 of the base plate 1 is provided for receiving the pieces 2.
The pieces 2 are made of plastic and pervious to light. The pieces 2 have image layers 21 sandwiched therein, and fitting portions 22 on the edges, which can be fitting protrusions 221 or fitting gaps 222; those of the fitting portions 22 that face in the same direction have the same shape.
Therefore, the pieces 2 can be positioned in the right places on the transparent middle portion 14 of the base plate 1 to form a complete picture with adjacent ones of the fitting portions 22 and 13 being fitted together.
To make the image layers 21, 12 of the pieces 2 and the protruding border 11 of the base plate 1, first a first acryl plate is formed in a mold, and next a piece of cloth or cast coated Kraft paper is positioned over the first acryl plate as the image layer, which has images of people, stories, things, scenery etc printed thereon with heat-resistant, easily fixable, high temperature resistant and light-resistant ink, and finally a second acryl plate is formed over the image layer and the first acryl plate; images can be printed on single or two sides of the cloth/cast coated Kraft paper.
Because images are printed on the image layers with heat-resistant, easily fixable, high temperature resistant and light-resistant ink, and the image layers are sandwiched between the acryl plates, the images have quality and attractive colors, which can't mix, fade or loss their brightness, and the image layers (paper/cast coated Kraft paper) can't distort, stretch, shrink or change shape, and the ink and the image layers can't crack.
From the above description, it can be seen that the jigsaw puzzle structure of the present invention has at least the following advantages:
1. The base plate and the pieces of the jigsaw puzzle are made of plastic materials therefore they are water-resistant, and can be played with in water.
2. The jigsaw puzzle is made of plastic materials therefore it has a relatively long service life, not gong to change shape even if it has been used for a long length of time.
3. The jigsaw puzzle is pervious to light therefore it will be relatively pleasant and unique looking, and can be used as a decoration after the pieces are pieced together, as shown in
4. The image layers are sandwiched in the pieces and the protruding border of the base plate therefore the user's hands won't be dirtied by the ink on the image layers, which may contain toxic substances.
5. It takes relatively much mental effort and is much fun to make the pieces fitted together in their correct places because those of the fitting portions of the pieces that face in the same direction have the same shape, thus preventing the user from guessing the correct positions of the pieces from the shapes of the fitting portions.
