Abstract
The present invention relates to a puzzle comprising a plurality of planar elements (54, 55, 57) and a main core member (53). When the plurality of planar elements (54, 55, 57) are assembled in a correct order then the planar elements (54, 55, 57) together define a recognizable three-dimensional figure (50). In some aspects of the invention the planar elements (54, 55, 57) comprise at least first (54) and second (55, 57) sub-groups of planar elements. The first sub-group of planar elements (54) are for assembly on the main core member (53). The assembled three-dimensional figure comprises a plurality of separately identifiable components (56, 58). One of the components (56, 58) is defined totally by the second sub-group of planar elements (55, 57) and is an entity identifiable separately from the remainder of the assembled puzzle. In some embodiments the planar elements (55) of the second sub-group are mounted on a branch core member (51). The planar elements of the second sub-group can be mounted on a branch core member so that they are not parallel to the planar elements of the first sub-group.

.











In

FIG. 1

there can be seen a puzzle


10


which comprises a plurality of planar elements


11


which extend generally horizontally in use. The planar elements


11


are mounted on a branched core member


12


which extends upwardly from a base


13


. Each of the planar elements


11


have at least one aperture through which the core


12


will pass in use. The planar elements have differing cross-sections and when the planar elements


11


are assembled in a correct order they together define a chosen three-dimensional shape, in

FIG. 1

the chosen shape being the head of a teddy bear.




The assembly of three-dimensional shapes from a plurality of planar elements is known from the applicant's products and earlier published patent specifications.




The present invention differs from the earlier puzzles in that the completed puzzle comprises a plurality of component parts, each part being formed from a sub-group of the total group of planar elements used to complete the puzzle. Thus, it can be seen in

FIGS. 2 and 3

that the eyes


7


and


8


and nose


9


of the teddy bear are formed each from sub-groups of planar elements


14


,


15


and


16


. In

FIG. 3

the cross-section shows the planar elements


16


together defining the eye


8


and the planar elements


15


together defining the eye


9


.




The core


12


has five different branches


20


-


24


. The branches


23


and


24


seen in dotted lines in

FIG. 1

are used as the supports for the planar elements


11


which define the ears of the teddy bear; each of these planar elements will have an aperture therethrough of a shape and size to match the cross-section of one of the branches


23


and


24


.




The branches


21


and


23


extend in a generally horizontal plane in use. The branches


21


and


23


are accommodated on matched grooves in two adjacent planar elements


11


, the grooves together defining two bores, one each for the branches


21


and


24


when the relevant planar elements are brought together. A number of the planar elements


11


will also define two eye sockets, one for each of the eyes


7


and


8


, the external peripheries of the planar elements


11


being shaped to provide the socket features. A sub-group of planar elements can be assembled sequentially in correct order on the part of branch


21


extending through a socket pre-formed by assembled planar elements


11


. The planar elements


14


when assembled in correct order on the branch


21


form the eye


7


. Each planar element


14


will have an aperture therethrough which matches in shade and cross-section the cross section of the branch


21


. The end of the branch


21


is threaded and the outermost one of the planar elements


14


will have a matching thread so that the element can be threaded on the end of the branch


21


and thereby secure all of the planar elements


14


on the branch


21


. In similar fashion, the branch


22


extends through a bore formed by matching grooves in adjacent planar elements


11


when they are brought into abutment with each other. The planar elements


16


will be mounted on the branch


22


(each element having an aperture therethrough which matches in shape and cross-section the cross-section of branch


22


) in an eye socket defined by the exterior surface of a plurality of the planar elements


11


. The planar elements


16


when assembled in correct order will define the eye


8


. The free end of the branch


22


is threaded and the outermost planar element


16


has a matching thread whereby the outermost planar element


16


can be used to secure the other elements


16


on the branch


22


in position in the eye socket.




The branch


20


extends through a bore formed by matching grooves in adjacent abutting planar elements


11


. A socket is defined on the exterior of the assembled teddy bear head for receiving the nose


9


. The socket is defined by the exterior shape of a plurality of planar elements


11


when assembled together on the core


12


. The plurality of planar elements


15


can be assemble on the branch


20


in a preformed socket in correct order to provide the nose


9


. The end of the branch


20


is threaded and the outermost planar element


15


is also threaded so that the elements


15


can be secured on the branch


20


.




It will be understood from the above description that the finished puzzle


10


comprises a number of different component parts; namely, the two eyes


7


and


8


, the nose


9


and the remainder of the head. Each component is formed from a separate sub-group of planar elements; the nose


9


from planar elements


15


, the eye from planar elements


15


, the eye


8


from planar elements


6


and the rest of the head from the planar elements


11


. The planar elements


11


are all parallel to each other in the finished puzzle. The planar elements


14


are all parallel to each other in the finished puzzle. However, the planar elements


14


are not parallel to the planar elements


11


in the finished puzzle. Indeed the planar elements


11


all lie on planes which are at right angles to the planes of the planar elements


11


. In a similar fashion the planar elements


15


are parallel with each other but not parallel with the planar elements


11


and the planar elements


16


are parallel with each other but not parallel with the planar elements


11


.




Each sub-group of the planar elements are preferably of different colours. For instance, the planar elements


11


could be brown, the planar elements


14


and


16


could be blue and the planar elements


15


could be red. This leads away from accepted practice since in general the prior art puzzles have all been made of pieces of the same colour.




Each sub-group of the planar elements can be of different materials. For instance, the planar elements


11


could all be of cardboard, whilst the planar elements


14


,


15


and


16


could be of plastic material. In this case the planar elements


15


would be made by a first manufacturing process and the planar elements


14


,


15


and


16


by a second different manufacturing process.




The planar elements


11


could each be a single unitary piece. In this case, the branches


20


-


24


will be detachable from the central core member


12


and planar elements slid down the main trunk of core


12


and then branches added on when necessary (the branches


20


-


24


could be push-fit or screw threaded). Alternatively, as shown in

FIG. 3

, at least some of the planar elements


11


could be formed of at least two pieces


11


A and


11


B, to be joined together in the manner of jigsaw pieces. In this case the core


12


and branches


20


-


24


could be formed as a single member and the planar elements


11


assembled from their constituent parts around the core


12


and branches


20


-


24


.




In a second embodiment of the invention, illustrated in

FIGS. 4 and 5

, a puzzle is again assembled to form a teddy bear's head. The puzzle of

FIG. 5

is also formed (as with the puzzle of

FIGS. 1 and 2

) of components each formed from a sub-group of planar elements, the sub-groups being preferably of varying colours and/or materials. However, unlike the puzzle of

FIGS. 1 and 2

, all of the planar elements in the second embodiment of puzzle are parallel or co-planar with one another.




Branches


51


and


52


which extend from a trunk of core


53


have portions which extend along axes parallel to and spaced apart from the axis of the trunk of core


53


. In the illustrated embodiment the trunk of core


53


extends vertically in use and the branch


51


has a portion


51


A which extends vertically and the branch


52


has a portion


52


A which extends vertically.




The branches


51


and


52


are accommodated in bores formed by matched grooves in adjacent abutting planar elements


54


(mounted on the trunk of core member


53


) and eye sockets are defined by the exterior surfaces of a number of the planar elements


54


. The branch sections


51


A and


52


A extend vertically in the eye sockets. A first sub-group of planar elements


55


are assembled in correct order on section


51


A to form an eye


56


. A second sub-group of planar elements


57


are assembled in correct order on the section


52


A to form an eye


58


. In this case it will be necessary to partly form an eye socket, then form an eye and then complete the eye socket.




A branch


59


is also provided with a vertically extending portion on which a plurality of planar elements


60


are assembled to form a nose


61


. The branch


59


will extend in a bore provided by matched grooves in adjacent abutting planar elements


54


and the nose


61


will be provided in a socket defined by the exterior of a number of the elements


54


. Again, the socket for the nose should be partly formed and then the nose formed and then the socket completed.




The planar elements


55


,


57


,


60


and


54


are all parallel or co-planar with each other. However, the planar elements


55


,


57


,


60


are of materials and/or colours different to those of the planar elements


54


.




Preferably the planar elements


55


,


57


and


60


are made by a first manufacturing process and the planar elements


60


by a separate second manufacturing process.




Whilst above the main trunk core member


12


is vertical and supported by a base, the trunk core member


12


could extend at any angle supported by a base or indeed be unsupported (e.g. both ends of the trunk core member


12


could be threaded and the extreme planar elements similarly threaded to secure all intervening core members on the trunk core member


12


).




Whilst above the branch core member


20


-


24


,


51


,


52


and


59


are shown connected directly to the trunk core member either permanently or detachably, the branch core members could be auxiliary core members supported only by one or more planar elements


11


and not directly attached in any way to the main trunk core member


12


. For instance, successive planar elements


11


could be provided with apertures which align on assembly to define a closed bore which would receive and support a branch core member.




In a third embodiment of the invention, illustrated in

FIGS. 6

to


9


, a puzzle


70


is again assembled to form a head of a teddy bear. The puzzle


70


is again formed of components, the components being varying colours and/or materials. However, unlike the first and second embodiments the eyes and nose of the teddy bear head are not formed on branch core members branched Off from a main core member


71


.




A sub-group of brown planar elements


72


form the main body of the head of the teddy bear. The planar elements


72


are all mounted on core members and each planar element has an aperture therethrough for accommodating a core member.




In a first variant of the third embodiment of the invention (

FIG. 7

) the eyes


73


,


74


and nose


75


of the teddy bear are each independent and separately identifiable components of the teddy bear head. The eye


73


is formed of a sub-group of planar elements


76


all parallel to each other and parallel to the planar elements


72


. The eye


74


is formed of a sub-group of planar elements


77


all parallel to each other and parallel to the planar elements


72


. The nose


75


is also formed of a sub-group of planar elements


178


all parallel to each other and parallel to the planar elements


72


.




None of the planar elements


76


,


77


and


178


are mounted on core members. Instead, a plurality of the planar elements


72


are provided with peripheral cut-outs (e.g.


78


,


79


). Each cut-out (e.g.


78


,


79


) is shaped as illustrated in

FIG. 7

to receive one of the planar elements


76


,


77


,


178


of the sub-groups of planar elements and to hold the received planar element in position. As the puzzle is built-up layer by layer, the planar elements


72


will be mounted one by one on the core member


71


. As the planar elements


72


with cut-outs are mounted then a planar element of one of the subgroup of planar elements


76


,


77


,


178


will be mounted in each cut-out in each planar element


72


on mounting of the planar element


72


on the core


71


. In this way, the planar elements


72


with cut-outs define sockets and the sub-groups of planar elements


76


,


77


,


178


form the eyes and nose of the teddy bear which are separately identifiable components of distinguishable colour or material firmly held in sockets defined by the planar elements


72


. As illustrated in

FIG. 7

, the planar elements


76


and


77


are roughly circular and the illustrated planar element


72


has two cut-outs


78


,


79


each of which has a surface which abuts and surrounds more than 180° of the outer circumferential surface or a planar element


76


,


77


in order to engage and retain the planar element


76


,


77


in position.




In a second variant of the third embodiment of puzzle, illustrated in

FIG. 8

, the cut-outs


78


′ and


79


′ of the planar element


72


′ mounted on core


71


have themselves cut-outs


80


,


81


,


82


and


83


which receive respectively lugs


84


and


85


on the planar element


76


′ and lugs


86


and


87


of the planar element


77


′. The interaction of lugs


84


and


85


with the cut-outs


80


and


81


holds the planar element


76


′ in place in the cut-out


78


′. The interaction of the lugs


86


and


87


with cut-outs


82


and


83


holds the planar element


77


′ in place in the cut-out


79


′.




In a third variant of the third embodiment of puzzle, the eyes


73


and


74


are more detailed in that they in themselves comprise two separately identifiable components, a white cornea and a black iris/pupil. Planar elements


76


″ and


77


″ define the white corneas of the eyes


73


and


74


and are held in place by interaction of lugs


94


,


95


with cut-outs


90


,


91


and interaction of lugs


96


,


97


with cut-outs


92


,


93


, in the same manner as the

FIG. 8

variant. However, the planar elements


76


″ which define the eye define a white cornea of the eye


73


and not the whole eye


73


and instead some of the planar elements


76


″ themselves have cut-outs


98


each of which receives a planar element


99


of a sub-group of planar elements


97


which together define a pupil/iris of eye


73


. The cut-outs


98


in the planar elements


76


″ are shaped to securely retain the planar elements


99


in place.




In the puzzle of the third variant, at least some of the planar elements


72


″ mounted on core


71


are each formed of two puzzle pieces


72


″A and


72


″B with co-operating lugs and cut-outs. As the planar elements


72


″ are mounted one by one on the core member


71


then when the planar elements


72


″ with forward cut-outs


78


″ and


79


″ are mounted on the core member, then appropriate planar elements


76


″ and


77


″ must be selected and inserted in the cut-outs


78


″ and


79


″. Also, appropriate planar elements


99


and


100


must be inserted in cut-outs


98


and


101


in the planar elements


76


″ and


77


″. When the puzzle is assembled then brown-coloured planar elements


77


″ will form the majority of the teddy bear head, while a sub-group of white planar elements


76


″ will form a white cornea of an eye


73


of the teddy bear, the planar elements


76


″ being secured in a recess defined by the planar elements


72


″, and a sub-group of black planar elements


99


will form a black pupil of the eye


73


, the planar elements


99


being secured in a cavity defined by the planar elements


76


″. In a similar way white planar elements


77


″ define a white cornea of the eye


74


and the black planar elements


100


define a black pupil of the eye


74


.




A fourth embodiment


199


of the puzzle is illustrated in

FIGS. 10 and 11

. In this embodiment the majority of a teddy bear head


199


is comprised of planar elements


200


mounted on a core member


201


. The planar elements


200


are each made of cardboard. Some of the planar elements have peripheral cut-outs, e.g. the cut-outs


202


and


203


illustrated in FIG.


11


. The puzzle


191


also has two eyes,


204


,


205


and a nose


206


. Each of these components is mounted in a recess defined by a plurality of the planar elements


200


.




In

FIG. 11

it can be seen that the cut-outs


202


and


203


each define part of sockets in which plastic eye components


204


and


205


are mounted and secured. The cut-outs in the planar elements


200


define in effect eye sockets in each of which a one-piece plastic eye


204


,


205


is secured. In assembly of the puzzle, each eye socket should preferably be half-formed and then an eye inserted in the half-formed socket before the eye socket is completed by mounting of further planar elements


200


. The nose


206


will in a similar fashion be located in a nose socket. The defined eye and nose sockets are shaped to firmly retain therein respectively one piece nose and the two one-piece eye components.

  • 7. A puzzle as claimed in claim 1 wherein the planar elements of the second sub-group are of a colour different to the colour of the planar elements of the first sub-group.
  • 8. A puzzle as claimed in claim 1 wherein the planar elements of the second sub-group are of a material different to the material of the plurality of planar elements of the first sub-group.
  • 9. A puzzle as claimed in claim 2 wherein the planar elements of the first sub-group are all parallel to each other, all of the planar elements of the second sub-group are parallel to each other and the planar elements of the first sub-group are not parallel to the planar elements of the second sub-group.
  • 10. A puzzle as claimed in claim 9 wherein the planes of the first sub-group of planar elements intersect with the planes of the second sub-group of planar elements at angles in the range of 30° to 90°.
  • 11. A puzzle as claimed in claim 1 wherein the planar elements of the first sub-group are manufactured by a first manufacturing operation and the planar elements of the second sub-group are separately manufactured by a second manufacturing operation.
  • 12. A puzzle as claimed in claim 1 wherein the planar elements of the first sub-group form the majority of the completed puzzle.
  • 13. A method of assembly of a puzzle as claimed in claim 1 wherein planar elements of the first sub-group are mounted on the main core member and then planar elements of the second sub-group are mounted overlaying and supported by the mounted planar elements of the first subgroup and then more planar elements of the first sub-group are mounted on the main core member, the planar elements of the first sub-group at least partly surrounding the planar elements of the second sub-group in the completed puzzle.
  • 14. A method of assembly of a puzzle as claimed in claim 1 wherein planar elements of the first sub-group are mounted on the main core member to define an externally facing socket, the second sub-group of planar elements are assembled within the said socket, the assembled planar elements of the second sub-group being partly visible in the assembled puzzle.
