Description

The present invention relates to a jigsaw puzzle set with a stand, and more particularly to a jigsaw puzzle set having a stand for leaning a jigsaw puzzle that uses a transparent jigsaw puzzle as a tool for "copying".

The transparent jigsaw puzzle of the present invention does not fall apart even if the completed jigsaw puzzle is hung vertically, so you can stand it up like a postcard and enjoy it.

INDUSTRIAL APPLICABILITY The jigsaw puzzle set of the present invention can be used as an educational, educational and learning tool for infants, school children and students, and can also be used to prevent brain deterioration in the elderly and is effective in delaying the progression of dementia.

Jigsaw puzzles are generally made of paper with an image printed on the surface of the paper. Recently, plastic jigsaw puzzles that use plastic instead of paper are also commercially available. A white jigsaw puzzle without a picture, that is, a plain paper puzzle is also known. Further, an acrylic transparent plastic jigsaw puzzle in which each piece is transparent is also known. White jigsaw puzzles and transparent plastic jigsaw puzzles are said to be difficult to complete because there are no images that can be a hint when combining the pieces.

A known transparent plastic jigsaw puzzle is made by laser cutting a transparent acrylic plate. However, since the transparent jigsaw puzzle of this acrylic plate is lost by laser cutting, the completed jigsaw puzzle cannot be hung vertically. Further, it is difficult to mass-produce inexpensively because of the processing cost of laser cutting.

In the patent application No. 2019-22736 dated February 12, 2019, entitled "Transparent Jigsaw Puzzle," the present inventor disclosed a transparent jigsaw puzzle that does not fall apart even if the jigsaw puzzle is vertically hung after completion. This patent application also describes an example in which a transparent jigsaw puzzle is used as a tool for a "photograph." However, this patent application does not describe how to store and sell the transparent jigsaw puzzle.

Japanese Patent Application No. 2019-22736

The problem to be solved by the present invention is to provide a jigsaw puzzle set for a copy picture, which includes a stand which allows a completed jigsaw puzzle to be set up and viewed like a postcard in a transparent jigsaw puzzle used as a tool for a "copying picture".

The jigsaw puzzle set for copying pictures of the present invention is a transparent plastic jigsaw puzzle (P), a writing tool (W) for drawing a picture on the transparent plastic jigsaw puzzle (P), a stand (S) for leaning the completed jigsaw puzzle, and the above-mentioned. It consists of a transparent plastic jigsaw puzzle (P), a writing instrument (W) and a container (C) that houses a stand (S) together.

An envelope (E) for putting the completed jigsaw puzzle into the container (C) and sending it to the other party can be further housed.

Since the transparent jigsaw puzzle of the present invention does not fall apart even if the completed jigsaw puzzle is hung vertically, the completed jigsaw puzzle can be erected on a stand like a postcard and viewed.
Jigsaw puzzles are generally sold in boxes, but with the transparent jigsaw puzzle set of the present invention, a writing tool suitable for "copying pictures" is enclosed, so that the user can use it immediately after purchase and stand the completed jigsaw puzzle. You can stand and enjoy it like a postcard.

The jigsaw puzzle set of the present invention can be sent after the jigsaw puzzle has been written into a jigsaw puzzle, after describing the thoughts and wishes of the user. Therefore, it can be used as a secret communication means between a person who is not good at directly transmitting one's thoughts to the other party, parents and children, friends, and specific circles. You can send it to the other party without breaking it apart. In this case, it is possible to play as a jigsaw puzzle after reading the thoughts and information of the opponent described in the jigsaw puzzle.

In the present invention, the "transparent plastic jigsaw puzzle (P)" is a jigsaw puzzle that is made by combining a plurality of pieces (p), each piece (p) is made of a transparent plastic material, and substantially all the pieces (p) are It means a transparent and plain jigsaw puzzle on which no image or print is applied, but an image or mark may be printed on a part of the piece.

In the present invention, "copying picture" means that the original picture (G) which is the original of the copying picture is arranged below the transparent plastic jigsaw puzzle (P) of the present invention, and the original picture (G) is copied on the surface of the transparent plastic jigsaw puzzle (P). It means that the original image (G) is copied and traced. In the present invention, for example, a letter that describes one's wishes to convey to a favorite person is written on a paper (original picture), and this paper is placed under a transparent plastic jigsaw puzzle (P) to display the surface of the transparent plastic jigsaw puzzle (P). The original image (G) can be copied (traced) on top. It can also be written directly on the surface of a transparent plastic jigsaw puzzle (P). When the learning content is stopped, the memory is ensured because it is repeatedly learned in the process of transcription and the process of playing as a jigsaw puzzle.

Any known writing instrument can be used for this "copying picture", but since the transparent plastic jigsaw puzzle (P) of the present invention is plastic, it must be a writing instrument that can be written on a plastic material. The writing instrument may be water-based or oil-based, and may be erasable. "Mckey" (registered trademark) of Zebra Co. can be preferably used for the copy-out of the jigsaw puzzle of the present invention, and "mackey" of various colors can be used for "copy-over". The number and type of writing instruments (W) are arbitrary.

The jigsaw puzzle set of the present invention can be used as a means of communicating one's feelings to the other party on Valentine's Day. After describing your feelings on the transparent plastic jigsaw puzzle (P), you can send it after separating it. By doing so, the opponent who got the jigsaw puzzle set of the present invention can know the feelings of the opponent depending on whether or not they complete the jigsaw puzzle.

The jigsaw puzzle set of the present invention can be used as an educational toy for infants. In the case of a jigsaw puzzle for infants, by reducing the number of pieces and increasing the size of each piece, the infant can be made to understand the image desired by the parent through the play of the jigsaw puzzle. Since the jigsaw puzzle of the present invention is made of transparent plastic, it can be washed and used many times if it becomes dirty.

The jigsaw puzzle set of the present invention can be used as a learning toy for school children. For example, by copying a map of Japan from the original image (G) and repeatedly remembering the map of Japan in the head while playing as a jigsaw puzzle, the memory becomes reliable.

The jigsaw puzzle set of the present invention can be used as an educational tool for students. For example, the periodic table of English words or chemical elements you want to memorize can be written on paper, copied onto a transparent plastic jigsaw puzzle, and the position of words or chemical elements can be reliably stored by repeated thought actions while playing as a jigsaw puzzle.

The jigsaw puzzle set of the present invention can be used as a means for preventing the brain deterioration of the elderly or a means for delaying the progression of dementia. The brain image can be evoked by copying the image that remains in the patient's impression and completing it as a jigsaw puzzle. The jigsaw puzzle set for copy-out of the present invention is useful for activating repetitive memory in the brain, and thus can be used in other fields requiring repetitive memory.

Container (C)
The container (C) houses the transparent plastic jigsaw puzzle (P), the writing instrument (W) and the stand (S) or the stand sheet (SS) together, and serves as a packaging container at the time of sale.

This container (C) can be any container. Generally, a transparent plastic packaging container which is commercially available at low cost can be used. Blister packs can also be used.

In another embodiment of the present invention, a hanging tab (C4) having a hanging hole that can be inserted into a pin of a display rack (L) is formed in a part of the container (C).

Writing instrument (W)
The writing instrument (W) is for drawing an image on the surface of the transparent plastic jigsaw puzzle (P), and any writing instrument can be used, but it is necessary to be a writing instrument that can be written on a plastic material. The writing instrument (W) may be oil-based or water-based. For example, "Mckey" from Zebra can be preferably used for the letter set of the jigsaw puzzle of the present invention. Although the number and type of the writing instrument (W) are arbitrary, usually, three colors of “mackey” of black, red and blue are enclosed.

Stand (S)
A stand (S) is enclosed in the jigsaw puzzle set for copying pictures of the present invention. This stand can be any stand. 4 and 7 show two different embodiments of the stand (S).

[FIG. 6] is a photograph of a 60-piece transparent plastic jigsaw puzzle leaning against the stand sheet (S) of [FIG. 4].
The stand (S) in FIG. 7 is a commercially available plastic stand. This stand is sturdy and can be folded and placed in the copy-making jigsaw puzzle set of the present invention, but it has the disadvantage of being a little bulky.

The stand (S) of FIG. 4 is a three-dimensional assembly of the stand sheet (SS) shown in FIG. This stand sheet (SS) can be manufactured easily and inexpensively by punching it out of a polypropylene sheet, and is lightweight, so it is preferable for the jigsaw puzzle set for copy-making of the present invention. When making the stand sheet (SS) shown in [Fig. 5], the shelf plate portion (S2) and its supporting portion (S3) are also cut when punching the outer peripheral cutting edge (M) of the stand sheet (SS) from the polypropylene sheet. Then, the fold lines (L1 to L5) and the hinge portion (shown by a dotted line) are formed.
In order to form the stand (S) of [Fig. 4], the shelf portion (S2) of the stand seat (SS) of [Fig. 5] and its supporting portion (S3) are pulled out forward, and the hinge portion (indicated by a dotted line) It suffices that the notch formed in the shelf portion (S2) is engaged with the cutting edge of the vertical plate portion (S1).

The square jigsaw puzzle can be displayed on the stand sheet (SS) by supporting it on the shelf (S2). At this time, stoppers (t1, t2) are formed to prevent the jigsaw puzzle from slipping and falling from the shelf plate portion (S2). This stopper (t1, t2) can be formed by making a notch in a shape corresponding to the stopper (t1, t2) in the shelf plate portion (S2). The stopper portions (t1, t2) face vertically upward when the shelf portion (S2) and the support portion (S3) are bent at the hinge portion (shown by a dotted line).

The heart-shaped Gusaw puzzle can be supported by the stand (S) of FIG. Therefore, a hole (H) for accommodating the lower end of the heart-shaped Gusaw puzzle is punched in the shelf part (S2). [FIG. 1] shows a state in which the lower end of a heart-shaped jigsaw puzzle is inserted into the hole (H) of the stand (S) of [FIG. 4] that is three-dimensionally assembled.

As an option, the following can be enclosed in the container (C) of the jigsaw puzzle set for copying pictures of the present invention:
1) Envelope (E)
The envelope (E) is for inserting the transparent plastic jigsaw puzzle (P) on which characters and pictures have been written. This envelope can be used to enclose the transparent plastic jigsaw puzzle (P), for example, after describing one's feelings in the transparent plastic jigsaw puzzle (P), or disassembling it. It can also be a mailing envelope. The size of the transparent plastic jigsaw puzzle (P) can be reduced to make it a standard size mail, and the size of the envelope (E) can be within 23 cm×12 cm×1 cm. The preferred embodiment of the letter set of the present invention uses a 30 piece transparent plastic jigsaw puzzle (P) with dimensions of approximately 15 cm x 12 cm x 1 mm, which can be mailed in a standard mail.
2) Template This template can be made into a sheet with holes in the shape of animals, cars, stars, alphabets, etc. that serve as a guide when writing letters and pictures with a writing tool (W) on a transparent plastic jigsaw puzzle (P). ..
3) Spare transparent sheet This spare transparent sheet is a practice transparent sheet used for practice before being directly written on the transparent plastic jigsaw puzzle (P) with the writing instrument (W).
4) Paper for drawing a sketch (several sheets)
A paper for drawing a sketch cut to the same size as the transparent plastic jigsaw puzzle (P) can be enclosed.

The number of transparent jigsaw pieces and the size of each piece can be appropriately selected according to the person playing the game, the infant, the schoolchild, the student, the elderly, and the puzzle lover. For example, a small 30 piece transparent jigsaw puzzle is suitable for decorating a finished product upright like a postcard. The transparent jigsaw puzzle set of the present invention can be applied to transparent jigsaw puzzles of B5 version, A4 version or larger. Since the transparent jigsaw puzzle used in the present invention is lightweight, the jigsaw puzzle set of the present invention can be applied to large jigsaw puzzles of A4 size or larger. If necessary, the container (C) can be reinforced by providing reinforcing ribs.

Generally, jigsaw puzzles are completely separated before they are shipped, but in the jigsaw puzzle set of the present invention used as a means of "copying", the jigsaw puzzles are packaged and shipped without being separated.

When the original picture (G) is enclosed in the jigsaw puzzle set of the present invention, the original picture (G) can be selected according to the application. When it is used as an educational toy for an infant, an original picture of the child's favorite profit and color is prepared, and the parent can copy the original picture on the surface of the transparent jigsaw puzzle to play the jigsaw puzzle made by the parent. At that time, it is also possible to apply a color by using a template (1) made by making holes of a desired shape in a transparent sheet as shown in FIG. It is also possible to practice the transfer by performing the transfer on the practice transparent sheet (2) shown in FIG. The template (1) and the practice transparent sheet (2) can be put in the container (C) together with the original image (G) at the time of sale.

When used as a learning tool for school children and students, various original pictures (G) can be selected. Jigsaw puzzles that require repetitive reflection are useful as a learning tool because iterative thinking is effective in keeping it in memory. For example, write an English word or chemical element periodic table you want to memorize on a paper, copy it onto a transparent plastic jigsaw puzzle, and remember the position of the English word or chemical element by repeating thought actions while playing as a jigsaw puzzle. be able to.

The transparent jigsaw puzzle of the present invention can be used as a means for preventing the brain deterioration of the aged or a means for delaying the progression of dementia. For example, the brain image can be recalled by copying the image remaining in the elephant or the image of interest and completing it as a jigsaw puzzle.

INDUSTRIAL APPLICABILITY The transparent jigsaw puzzle for copying pictures of the present invention is useful for activating the repetitive memory effect of the brain, and thus can be used in other fields requiring the repetitive memory effect.

Transparent plastic jigsaw puzzle (P)
The transparent jigsaw puzzle (P) used in the jigsaw puzzle set for copying pictures of the present invention is characterized in that it does not fall apart even if the completed jigsaw puzzle is hung vertically. Each piece (p) of this transparent plastic jigsaw puzzle (P) is preferably composed of the following (i) to (iii) (see [FIG. 10]):
(I) A jigsaw puzzle body layer (1) made of a transparent plastic sheet having elasticity,
(Ii) a transparent surface layer (2, 2') made of a transparent plastic material and arranged on the upper surface and the lower surface of the jigsaw puzzle body layer (1),
(Iii) A bonding layer (3, 3') disposed between the jigsaw puzzle body layer (1) and each transparent surface layer (2, 2').

The transparent surface layer (2, 2') and/or the jigsaw puzzle body layer (1) is made of polypropylene (PP), polyethylene (PE) and their copolymers, alloys or combinations, polyvinyl chloride (PVC), polyethylene terephthalate (PET). ), polycarbonate (PC), acrylic resin, and silicone resin.

In the present invention, substantially all the pieces (p) are transparent and plain without any image or printing, but even if an image or a mark is printed on a part of the transparent jigsaw puzzle piece (p), it is a book. It does not depart from the scope of the invention. This printing can be formed on the surface of the transparent surface layer (2, 2') and/or on the back surface in contact with the jigsaw puzzle body layer (1).

The term "transparent" used in the present invention has no strict definition, and a jigsaw puzzle is transparent if the back surface of the jigsaw puzzle is visible when viewed from one side of the jigsaw puzzle. Therefore, a translucent polyethylene sheet is also transparent in the present invention. Preferably, "transparent" is a transparent plus chok material having a haze value of about 40, preferably a haze value of about 10, and more preferably a haze value of about 5.

Jigsaw puzzle body layer (1)
The jigsaw puzzle body layer (1) used in the present invention is not particularly limited as long as it is a transparent and elastic plastic sheet. Generally selected from polypropylene (PP), polyethylene (PE) and their copolymers, alloys or combinations, polyvinyl chloride (PVC), polyethylene terephthalate (PET), polycarbonate (PC), acrylic resins, silicone resins. It In addition, materials derived from lactic acid-based renewable sources can be used as long as they are transparent.

The material of the jigsaw puzzle body layer (1) is transparent, the fit when playing as a jigsaw puzzle, the adhesiveness with the transparent surface layer (2, 2') laminated on it, the cuttability, the cost, etc. select. Transparency can be selected variously, and it is not necessary to be completely transparent (haze=0). Sometimes some opacity is suitable for playing as a jigsaw puzzle.

In order to be able to lift the completed jigsaw puzzle vertically, a material having a certain degree of elasticity, elasticity and flexibility is selected as the material of the jigsaw puzzle body layer (1). In order to impart elasticity, it is generally preferable to use an olefin elastomer material or an olefin material added with a rubber component. In the case of PVC or the like, the flexibility of the jigsaw puzzle body layer (1) can be adjusted by adding a plasticizer. This elasticity, elastomericity, and flexibility can be such that the completed jigsaw puzzle can be lifted vertically.

A rubber component is generally added to give elasticity to a plastic material. For example, an ethylene component is added to polypropylene (PP), a butadiene component is added to polystyrene (PS), and a methyl methacrylate is added to polyvinyl chloride (PVC). It is known to add a butadiene-styrene copolymer (MBS) component. However, in the present invention, the jigsaw puzzle body layer (1) should be more transparent.

The term "transparent" used in the present invention has no strict definition, and a jigsaw puzzle is transparent if the back surface of the jigsaw puzzle is visible when viewed from one side of the jigsaw puzzle. Therefore, a translucent polyethylene sheet is also transparent in the present invention. Preferably, "transparent" is a transparent plus chok material having a haze value of about 40, preferably a haze value of about 10, and more preferably a haze value of about 5.

Transparent surface layer (2, 2')
The transparent surface layers (2, 2') arranged on the upper surface and the lower surface of the jigsaw puzzle body layer (1) are made of the same kind of material as the material of the jigsaw puzzle body layer (1) from the viewpoint of stackability. Is preferred. No elasticity is required for this transparent surface layer (2, 2'). Selected from transparent polypropylene (PP), polyethylene (PE) and their copolymers, alloys or combinations, polyvinyl chloride (PVC), polyethylene terephthalate (PET), polycarbonate (PC), acrylic resin, silicone resin it can. These polymers may be homopolymers, copolymers or alloys. From the viewpoint of cost and hardness, in the present invention, it is preferable to select the above plastic material as a material that can be practically used as a jigsaw puzzle. For example, it is preferable that the jigsaw puzzle body layer (1), the transparent surface layer (2, 2') and the bonding layer (3, 3') are all made of propylene or all of polyethylene. It is also possible to use ABS, AS, polyamide, polyacetal, fluororesin, epoxy resin, polyester resin. Also, materials based on lactic acid obtained from renewable sources can be used. The above resin generally has a haze value of about 0.1 to 8. In the case of polypropylene or polyethylene, the haze value can be lowered by adding a nucleating agent.

When printing an image on a part of the transparent surface layer (2, 2'), the material of the transparent surface layer (2, 2') is transparent biaxially oriented polypropylene (OPP) or high density polyethylene (HDPE). By doing so, the image can be printed precisely.

If no image is printed on the transparent surface layer (2,2'), the transparent surface layer (2,2') may be an unstretched material, such as unstretched polypropylene (CPP) or low density polyethylene (LLDPE). it can. This unstretched sheet may be extruded directly from an extruder, but generally, the jigsaw puzzle body layer (1) and the transparent surface layer (2, 2′) are made of the same kind of material and have different physical properties. Is preferred.

Bonding layer (3, 3')
The material of the bonding layer (3, 3') varies depending on the material of the transparent surface layer (2, 2') and the jigsaw puzzle body layer (1). The role of the bonding layer (3, 3') is to bond the transparent surface layer (2, 2') and the jigsaw puzzle body layer (1) together to form a laminated body. It is advantageous to carry out the lamination integration by thermal bonding. Since the plastic material used in the present invention is a hard-to-adhere material, the bonding layer (3, 3') material is used to bond the transparent surface layer (2, 2') and the jigsaw puzzle body layer (1) only by thermal lamination. The choice of becomes important.

When polypropylene (PP) is selected as the material of the transparent surface layer (2, 2′), it is preferable that the jigsaw puzzle body layer (1) is also polypropylene. Specifically, the transparent surface layer (2, 2') is biaxially oriented polypropylene (OPP) or unstretched polypropylene (CPP), and the bonding layer for thermal lamination (3, 3') is unstretched polypropylene (CPP). By doing so, the transparent surface layer (2, 2') and the jigsaw puzzle body layer (1) can be bonded with a practical peel strength only by thermal lamination. When the transparent surface layer (2, 2') is unstretched polypropylene (CPP), the bonding layer (3, 3') may be omitted in some cases. However, it is preferred to use a thin bonding layer (3, 3') for heat bonding.

Polypropylene (PP) and polyethylene (PE) are the same polyolefin materials, and these can be used in appropriate combination. When a material other than the polyolefin material such as PET is used, unstretched polypropylene (CPP) or low density polyethylene (LLPE) can be used, and if necessary, another compatible bonding layer (3, 3') can also be used. Low-density polyethylene is generally expressed as LDPE, but in the present invention, since commercially available linear low-density polyethylene (LLPE) called Roden is generally used for applications such as plastic bags, low-density polyethylene is expressed as LLPE. In the present invention, expressions such as LDPE, LLDPE and LLPE mean the same thing. When the adhesiveness is insufficient, a primer treatment, a surface treatment, or an adhesive can be used.

When polyvinyl chloride (PVC) is selected as the material of the transparent surface layer (2, 2'), it is preferable that the jigsaw puzzle body layer (1) is also made of polyvinyl chloride. Specifically, the transparent surface layer (2, 2') can be a hard or soft polyvinyl chloride sheet, and the bonding layer (3, 3') can be a soft polyvinyl chloride sheet. When the adhesiveness is insufficient, a primer treatment, a surface treatment or an adhesive is used.

When polyethylene terephthalate (PET), polycarbonate (PC) and acrylic resin are selected as the material of the transparent surface layer (2, 2'), the jigsaw puzzle body layer (1) is preferably made of these materials, but the jigsaw puzzle There are few materials that satisfy the properties as the main body layer (1) such as elasticity, fittability, flexibility, etc. and have reasonable costs.

The surface of these layers can also be treated in order to increase the adhesion between the transparent surface layer (2, 2') and the jigsaw puzzle body layer (1). Specifically, primer treatment or physical treatment (ultraviolet irradiation treatment, corona discharge treatment, plasma treatment, etc.) can be performed. Additional adhesive may be used if desired.

The thickness of the jigsaw puzzle body layer (1) is not particularly limited, but is generally 0.5 to 20 mm, preferably 0.6 to 15 mm, more preferably 0.7 to 10 mm.
The thickness of the transparent surface layer (2, 2') is not particularly limited, but is generally 0.05 to 2 mm, preferably 0.1 to 1 mm.
The thickness of the tie layer (3, 3') is generally 0.05 to 1 mm, preferably 0.1 to 0.8 mm.

It is not known why the jigsaw puzzle completed by the present invention can be lifted vertically, but the jigsaw puzzle body layer (1) having an elastic body and the transparent surface layer (2, 2') which is not an elastic body are adjacent to each other. It is considered that this is because the pieces are held in close contact with each other, but the present invention is not limited to this description.

In a preferred embodiment of the present invention, the jigsaw puzzle body layer (1) is made by adding polypropylene containing a rubber component to general-purpose polypropylene to make the jigsaw puzzle body layer (1) an elastic body, and the transparent surface layer (2, 2') as a rubber component. Use polypropylene that does not contain. The elastic jigsaw puzzle body layer (1) can be made by adding an elasticity-imparting agent to a homopolymer of propylene or by using a block copolymer or a random copolymer having a rubber phase.
