Abstract

This invention relates to a jigsaw puzzle (10), a method of assembling a jigsaw puzzle and to a jigsaw puzzle set. The pieces (12) of the jigsaw puzzle inlcude a backing element (18) which defines a first surface (20) and an opposed second surface (22). Part of a picture for a complete jigsaw puzzle is provided on the first surface and there is a coating of adhesive (24) on the second surface. The adhesive surface on the second surface is covered with a protective strip (26). In use, the protective strip is removed from the jigsaw puzzle piece and the piece is placed onto a mounting sheet (16) to which the adhesive bonds. Once the puzzle is assembled, it is adhered to the mounting sheet, so that it can be kept in an assembled state.

Description

JIGSAW PUZZLE
BACKGROUND OF THE INVENTION
This invention relates to a jigsaw puzzle.
A jigsaw puzzle consists of a picture on paper or wooden board, which is cut into irregular interlocking pieces to be reassembled. The puzzle is reassembled by identifying parts of the picture on each piece that match and also by identifying shapes that match. Once the puzzle has been completed it can be taken apart. Sometimes it is desirable to keep the puzzle in an assembled state, for example if the picture is to be mounted.
It is an object of this invention to provide a jigsaw puzzle that may be kept in an assembled state. SUMMARY OF THE INVENTION
According to the invention there is provided a jigsaw puzzle including:
a backing element defining a first surface and an opposed second surface; a part of a picture on the first surface; and a coating of adhesive on the second surface.
The adhesive may be permanent or it may be a contact adhesive.
Advantageously, the adhesive is a hotmelt permanent adhesive.
Preferably, the adhesive is covered with a protective strip that can be peeled off, to expose the adhesive.
The invention also covers a method of forming a jigsaw puzzle, the puzzle including a plurality of jigsaw puzzle pieces as described above, which may be assembled to form a picture, the method including the steps of:
assembling the puzzle on a first sheet of material having a surface which does not bond with the adhesive on the puzzle pieces; and transferring the assembled puzzled onto a second sheet of material having a surface which does bond with the adhesive on the puzzle pieces.
The invention further covers a jigsaw puzzle set including:
a plurality of jigsaw puzzle pieces as described above, which may be assembled to form a picture; and a first sheet of material which is the same size or larger than the assembled puzzle, the first sheet having a surface which does not bond with the adhesive on the puzzle pieces. The surface on the first sheet may be made from silicone.
Advantageously, the set includes a second sheet of material which is the same size or larger than the assembled puzzle, the second sheet having a surface which does bond with the adhesive on the puzzle pieces.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a pictorial view of a jigsaw puzzle according to the invention;
Figure 2 is a cut-away perspective view of a jigsaw puzzle piece from the puzzle illustrated in Figure 1 along the line 2-2; and
Figure 3 is a upside down pictorial of a jigsaw puzzle piece from the puzzle illustrated in Figure 1.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Referring to Figure 1 , a jigsaw puzzle 10 according to the invention comprises a plurality of jigsaw puzzle pieces 12. The pieces 12 have an irregular shape and are arranged to be joined together to form a picture. In this embodiment, the puzzle 10 is assembled on a sheet of material in the form of a mounting sheet 16, which is the same size as, or slightly larger than, the puzzle once it is assembled.
Referring to 2, each puzzle piece 12 includes a backing element 18 made from a sheet of rigid material, such as cardboard, wood or plastic. The backing element 18 defines a first surface 20 which bears part of the picture mentioned above and a second, opposed, surface 22. The second surface 22 is coated with an adhesive composition 24. The adhesive composition may be a contact adhesive which is non-permanent, or a permanent adhesive. The adhesive 24 is covered with a removable protective strip 26.
Referring to Figure 3, the removable protective strip 26 may be peeled away to expose the adhesive coating 24 on the second surface 22.
Referring back to Figure 1 , in use, once the location of a piece 12 has been identified on the puzzle, the protective strip 26 is peeled off and the piece 12 is placed in position on the mounting sheet 16 so that the piece 12 adheres to the mounting sheet 16. This step could be permanent, for example where the mounting sheet 16 is a normal sheet of paper and the contact adhesive bonds to it permanently. Alternatively, the step could be temporary if the adhesive on the piece 12 is a contact adhesive.
Although the method of assembly described above works for small puzzles (puzzles having less than 20 pieces), there are problems with larger puzzles having 100 or more pieces. When a large puzzle is assembled on a mounting sheet, small gaps are formed between the pieces as they are adhered to the mounting sheet. These small gaps are compounded by the number of pieces and the puzzle does not fit together properly.
This problem is addressed by providing a first mounting sheet having a surface to which adhesive on the jigsaw puzzle pieces does not adhere. The mounting sheet will be the same size as, or slightly larger than the completed puzzle. Advantageously, the first mounting sheet is made from silicon release paper, such as that sold under the trade name GLASSINE. In use, the protective strip is peeled off a piece of the puzzle and the puzzle is built on the first mounting sheet. Once the puzzle has been completed, it is transferred to a second mounting sheet. The first mounting sheet, together with the assembled puzzle, is placed on top of the second mounting sheet and the first mounting sheet is pulled out from underneath the puzzle. The second mounting sheet has a surface which bonds with the adhesive on the puzzle pieces. The second mounting sheet may be normal paper, typically paper having a thickness of 46-50 g/m2. The puzzle pieces are then caused to adhere to the second mounting sheet by applying pressure, for example by way of a rolling pin, to the pieces on the mounting sheet.
The method of assembling a puzzle described above can be used for any size puzzle and works for very large puzzles having a thousand or more pieces.
According to a preferred embodiment of the invention there is provided a jigsaw puzzle set, the set including a jigsaw puzzle having pieces as described above, a first sheet of paper which is the same size as or larger than the assembled puzzle and having a surface which does not bond with the adhesive on the puzzle pieces, and a second sheet of paper which is the same size as or larger than the assembled puzzle, and which has a surface which does bond with the adhesive on the puzzle pieces. The set may also include a device for applying pressure to the puzzle pieces once the assembled puzzle has been transferred to the second sheet of paper. The device may be a simple plastic roller that can be rolled over the assembled puzzle.
Once the puzzle is completed on a mounting sheet to which the puzzle pieces have adhered, it can be kept in the assembled state. This is useful for jigsaw puzzles that a person may want to have mounted, for example, photographs of nature and wildlife. Also, once completed, the puzzle can be transported without worrying that it will fall apart.
