Abstract

A jigsaw puzzle holder comprises a base with perimeter walls and one or two lids which are readily detachable from the base. The lids are further divided into two sections, which are hinged so that the lids may be folded. The base is concave or convex, and has support pads upon which the pieces are placed. The pads may be circular or semi circular in shape. The lid traps the pieces against the support pads and holds them in place.

Description

JIG SAW PUZZLE HOLDER

This invention relates to a Jig Saw Puzzle Holder.

Jig Saw Puzzle holders are well known items,and are used for constructing or storing a completed or partially completed jig saw puzzle.The holder comprises of a jig saw puzzle construction base,usually with the base having the form of an oblong shaped working surface area,and the thickness of the base being sufficient to give it stiffness.Holders often include one lid or two lids,to help contain the puzzle pieces.The fully or partially constructed jig saw is sandwiched in betwen the base jig saw puzzle construction surface and the overlying lid.The jig saw puzzle is constructed once the lid has been seperated from the base working surface, leaving the latter fully exposed.

Puzzle holders can however be problematic when the user wishes to use the lid or lids for partial construction of the jig saw puzzle,because the lids can be cumbersorne,especially in restricted spaces.

According to the present invention there is provided a jig sa puzzle holder comprising a base,in the form of an oblong tize and including one or two lids.There are means for releasabj securing the lid or lids to the base,and the lid or lids incorporate automatically adjusting features, which allow vary ng thicknesses of puzzle pieces to be held in place onto the bay A specific embodiement of the invention will now be described by way of example with reference to the accompanying drawing in which.

Ref fering to the drawing the jig saw puzzle holder comprises various shaped lids,all of which can be fitted to the same base design,which is a type l,and there are eight different types of lids,which are types I to 0releasable hook and loop fasteners are used to secure or fasten the different type lids to the type l,base.

The type 1 base,l,figs 19,21 and 22,cornprises a top laminate member 9, figs 1,2,6,10,14,19,21,22 and 28, and this member is permanently secured or fixed to the bottom base member l0,tigs 3,4,5,13,19,21 and 22 by using a bonding agent,and the bonding agent exists or is applied in between the underside surface 22,figs 14,19,21,22 and 27 of the base top member 9,and the upper or top surface 23,figs 3,5,13,19,21 and 22 of the bottom member 10.The upper surface of the base bottom member t0, and this top surface being 23, suppcrts the underside surface 22,of the base top member 9,and the bonding agent between the top and bottom base laminates,holds the two members together and prevents slip or movement between members 9 and 10.The use of the bonding agent to prevent slip or movement between the two members,creates a stiff and fairly strong jig saw puzzle puzzle holder base,and this is achieved by the base top and the base bottom bonding together as if they were one component, which harnesses the structural strength from each of the two members.

On assernbly,and to position correctly and locate together the top base member 9,relatively to the base bottom member 10, the raised rims or generally per.peridcJr --Ldcat0and 21 that extend or protrude their corresponding members 9 and 10, are in apposition or locate alongside one to the otherThe raised fIms 20,figs 2, 14,19,21,22 and 28,overlap and surround the corresponding raised rims 2l, figs 3,5,13,19,21 and 22, location rims 20,are on the base top member 9, and the location rims 21,are on the bottom base member lOThe inner location perimeter rim surface 24,figs 2,14,19,21 and 22,on base top 9, completely surround the outer perimeter rim surface 25,figs 3,5,13,19,21 and 22,on base bottom l'Qi.The bonding agent exists or is applied between surface 24 and 25,again to give the base as a whole more rigidity and strength.

The previously described method or arrangement for fitting the base laminate top 9,to the base laminate bottom l0,is also used to fit the various types of jig saw holder lid top laminates to their corresponding or mating lid bottom laminates, with these lid assemblies being types 1 to8.This method of using location surfaces 24 together with 25 foilbcating members together7 can be described as method A and will be mentioned in the preceeding pages to describe lid laminate assemblies.

The purpose and mechanical functions of a jig saw puzzle holder are to provide the user with means to construct a jig saw puzzle onto a base,and further,to trap or secure the jig saw puzzle pieces,and in their constructed position.to form a jig saw puzzle,between the holder lid or lids,and base,with the lid or lids being releasably secured to to their corresponding or cooperable base memberVarious designs of lids and base assemblies can be used,and with the lids and base having different structural,construction features.A type 1 base,is used for all the jig saw holder assemblies that are ref fered to in this patent.The type 1 base,includes a top member 9,and a bottom member l0.The top member 9, includes a jig saw puzzle construction surface 27,figs 1,10,14,19,21,22 and 28,a convex or domed shaped top layer 28,figs 14,19,21,22 and 28,the jig saw puzzle construction surface 27, is made convex or dome shaped, and there are location rims or raised rims 20,figs 2,14,19, 21,22 and 28,a puzzle construction area cavity wall 29,figs 1,10,14,19,21,22 and 28,cavities or pockets used to accomodate hook and loop fasteners 30,figs 1,10,11,12 and 20,inner rim location surfaces 24, figs 2,15,19,21 and 22,base top member 9,underside rtoplayerT surface, 22 figs 14.19,21,22 and 27.The base bottom member 10 includes,circular ribs or pads4l,figs 13,19,21 and 22,a raisedside or outer rim location surface 25,figs 3,5,13,19,21 and 22.The circular support pads or ribs 4lstrengthen the base bottom lO,and provide strong support for the base top member 9,1 urther there are the jig saw puzzle pieces 33,ligs 10,19, 21 and 22,and the jig saw holder resting surface 32,figs 13,19,21 and 22. There are two main purposes for having a convex or domed shape,jig saw puzzle construction 9.

surf ace,and one purpose is to help the puzzle pieces 33,adhere to,or grip the base when the jig saw puzzle holder is fully asseled with the lids fitted to the base,and the other purpose is to provide a more rigid base,which is more resistant to distortion when pressure is applied to the base by the lids.

A type l,base l,used in conjunction with a type l,lid 2,figs 6 and 22,and type 2.lids 3,fLgs,i9and20 SLiustrateandshowthe functions of the assembled lid or lids and base.The type l,lid l,comprises,two half lids and a central interconnecting hinge, 34,figs 6,7,18 and 22,and the type 2,lids 3,comprise again two half lids which are identical in shape or design to the type l,and the type 2,lids 3,figs 19,20,but the type 2,lids have no interconnecting hinge and operate seperately,however the same mechanical principles are used to trap the puzzle pieces 33,onto the base with lid type l,as with lids type 2.

Although the half lids are the same shape and design in types I lid and type 2 lids,the lids in type 2 are narrower,and lie adjacent to each other when fitted to the base,as opposed to the type 1,lid where the central flexible hinge seperates the two half iids,forming one lid instead of two.Further the type 1,and 2,lid tops ll,figs 6,7,8,9,16,17,19,21,22,29 and 30 are fitted to their corresponding lid bottoms 12,figs 7,11,12,15, 19,20,21 and 22 by method A as previously described.Lid types 1 and 2 are releasably fitted to the base via automatically adjustable hook and loop fasteners,25 hichai' càred n pockets or cavities 30,and when the lids are secured to the base,the pressure pad surface 35,figs 11, 12,15,20 and 22 will come into contact with the jig saw puzzle pieces 33, the contact surface 35,which lie on the lid or lids underside figs,11,12, 15,19,20 and 22 and provide a concave dome shape and the dome shape forms the tops of the circular ssuepads or ribs that are an integral part of the type l,and type 2,lid bottoms l2,and the size of this lid dome shape is the same size as the dome shaped base construction surface 27,butii:s the selected thickness size of the most popular jig saw puzzle pieces. To be more precise,the lid dome radius 35è

- -- -

- - - a - - - - as the base dome radius 27,but plus the puzzle piece thickness which is 1- 25mm. The dome radius being the radius of surface 27 The reason for the precise size selection of lid and base dome radii,is because these domed surfaces need to be made or constructed,relative to each other,so that the puzzle pieces 33,will remain in their constructed position when the lids are fastened or closed onto the base,and to explain -how this is achieved reference is made to various illustrations included in figs 1 to 46.

Fig 6,shows a section line taken along the length of a fully assembled jig saw puzzle holder,and the holder comprises a type 1 base l,and a type 1 lid 2.The section is taken centrally across the width of the lid and base assernbly,and section drawing fig 22 illustrates or shows fully the lids 2.attached or fixed to the base l,and the jig saw puzzle pieces 33, held or trapped between the lid and base.The base comprises a top member 9,and a bottom member l0,and the lid 2,cornprises two identical half lids with top members li,and bottom members 2, - and the lid topand bottom members are fitted together by method A.has are the base top and bottom members.The user constructs the jig saw puzzle pieces 33,onto the dome shaped construction base surface 27,shown in figs 10,22 and partial views figs 33,34 and 37.The partial or complete jig saw puzzle construction is held onto the base l,by the lid 2,via velcro releasable fastenings,and once the lid 2,is fitted,the concave,half dome shape of the pressure pad surfaces 35,that are on each half of the lid,press onto the top surface or surfaces of the jig saw puzzle pieces,and in turn the bottom surfaces 37,of the jig saw pieces,press downwards onto the base construction surface 27,and the puzzle pieces are hld in betwwen the lids 2, and base l.An exploded partial view in figs 33,34 and 37 show exactly,the working of this mechanism,and using these figs, it can be explained how this arrangement works.

Fig 33,shows the jig saw puzzle pieces 33,but no pressure other than extremely light pressure,havirig been applied b' the lid pressure pad surface 35,and the puzzle piece 33, therefore has a flat shaped top surface 36and a flat bottom surface 37,and in this position,the gap 39, will exist betwerx :il.

surface 27.The top corner of the jig saw pieces 38,will be in very light contact with the lid pressure pad surface 35, and in this position it would be possible for the jig saw pieces 33,to slide or move laterally, and into varying positions,between the lids and base,and this feature of course would be unsatisfactory for the user,because the jig saw puzzle or the individual puzzle pieces would not be held in place.Once the lid is pressed further down onto the base or nearer to the base,pressure,will be will be applied by the lid surface 35,and onto the top surface or surfaces 38, of the puzzle pieces 33,and once sufficient pressure is applied,the puzzle pieces will distort or bend slightly and create full contact betwween the jig saw piece,top or upper surface 36,and the lid underside pressure pad surface 35,and the bottom surface of the jig saw pieces 37,will come into full contact with the base puzzle construction surface 27The drawings that show the puzzle pieces 33,trapped in this way and between the type l,lid and the type l,base are figs 22 and 34which show the lid positions,relative to the base positions when the lids are fully fastened to the base.When the holder is fully closed the jig saw pieces 33,will be held firmly between the concave dome shaped underside lid surface 35,and the convex dome shaped jig saw puzzle construction surface 27, of the base memberThe partial section view fig 34,shows the distorted or curved shaped puzzle pieces 33,and the downward pressure exerted onto the puzzle piece surface 33,by the lid surface 35, will result in more pressure being exerted nearer to the edges 38,fig 34, of the puzzle piece,rather than near its centre 46,and this difference in pressure is due to the fact that more downward pressure is needed around the puzzle piece edge areas 38,however on bending the puzzle piece, a pressure equal to this,is applied downward onto the construction surface 27,and this downward pressure occurs on the puzzle piece underside centre area 45,fig 34,so it is safe to say that there is more pressure created around the top edges,and the underside centre of the jig saw piece than on the remaining jig saw piece surface,top and bottom surface areas.A combination of pressures on a single jig saw piece or pieces,which lie between the base and lids,results in the puzzle piece or pieces being held firmly onto the jig saw base, by down pressure from the l.ids, however the curving of the jig saw piece or pieces between the lid concave dome shaped surface and the base convex dome shaped surface,helps to trap the puzzle piece more firmly,than between flat surfaces.If the lid and h-sè puzzle piece contact surfaces were moulded flat in manufacture,the settled moulded surfaces would be undulating, the settled moulded surfaces refer to the puzzle piece contact surfaces cooling and shrinking,following rnanufacture,and these surfaces would then be uneven, and this condition is shown in fig 40,were the contact surfaces on the lids and base 47,trap the piece 33,and the gaps 48,are not in contact with the puzzle piece, 33,and surfaces 49 are not in contact with the puzzle piece, so the piece is not trapped adequately.In fig 39 the lid and base contact surfaces6 are parrallel to each other and trap the puzzle piece 33,very well,but as already stated the surfaces 5,would not be flat and parrallel.Since the purpose of the jig saw holder is to trap the puzzle pieces and prevent them from moving or sliding betweeen the lids and base an improvement needs -to be made on, relying, on flat moulded surfaces to trap the pieces,for instance1the domed lid and base contact surfaces as previously mentioned.The domed shaped surfaces however,will not be as undulating after moulding,but even if the domes were equally as undulating,the corner edges of the puzzle pieces could still be in contact with the lid dome surface,and in sufficient contat to apply a small amount of downward pressure onto the puzzle pieces,which can be enough to stop the pieces sliding or moving between the holder lids and base,and this technique is shown in fig 33,were the puzzle piece edges 38,just come into contact with the lid pressure pad 35,and are just holding the pieces in place.Fig 33,can show two things,one being that the puzzle pieces are in such light contact with the lid,that the puzzle pieces could move,but on the other hand,the drawing could also show that 13.

there could just be enough contact with the edges 38,so as to just hold the puzzle piece or pieces in place,and either way the drawing looks the same because the amount of curvature required to hold the pieces in place could be so slight that it could not be observed by the naked eye.Fig 37, shows a partial section through a type l,or type 2,lid and base,and this drawing shows a puzzle piece 33,that is very slightly curved and is observable by the naked eye,but if the curve were to be formed by a bigger radius it would be difficult to see,however fig 3, shows that a puzzle piece that is only under slight pressure from the lid can still be trapped onto the base, and although gaps 51 and 39 exist between the puzzle piece and contact surfaces,the piece is still trapped sufficiently for securing purposes.

The type 2,lids in fig 19 are readily detachable or releasably fastened to the base,and each half lid covers half or substantially half of the jig saw construction surface area 27,the lid underside 35,js again dome shaped and has the same size curvature as a type l,lid dome.The type 2 lid works in exactly the same way as the type 1,lid when it comes to trapping the jig saw piece or pieces between the lids and base,however the type 2,lids do not have the central interconnecting hinge that the type l,lid has,but both the type l, and type 2, lids have another common feature which is again shown in other figs, Tabulated below are all the important or neccessary features belonging to the various types of lids 1 to 8,and the type 1, base.

A further common feature that the type l,type 2 and type 3 lids have is that the hook and loop fasteners 26,work or are utilised in the same way. The type 3 lid 4,fig 23 comprises,one lid,and the lid covers or substantially covers the whole of the jig saw puzzle construction surface 27.The puzzle pieces 33,are trapped between the lid domed surface 35,and the base construction surface 27,and the type 3 lid utilises the same mechanical principles to trap or hold the puzzle pieces onto the base,as do type 1 and 2 lids.Lid types 1,2 and 3 have an outer guard that protects the whole of the base edges once the lids are fitted to the base. The guard is made up of,lid top raised rims 52,lid bottom outer raised rims 53,and rims 52 and 53,surround the lid bottom inner raised rim 54,and the inside edge of the lid bottom inner raised rim,locates alongside the outer perimeter of the base edges,with layers 52,53 and 54 providing the base guard.The lid types 4,5,6,7 and 8 do not include guard location rims,but just locate inside the base jig saw cavity wall 29, and the lid types 4 to 8 each deploy a slightly different mechanical principle for trapping the puzzle pieces onto the base.Lid types 4 to 8 all include top and bottom laminate members but the interconnecting surfaces on each top and bottom laminate are arranged differently,and each provide different mechanical, working principles that are utilised to trap the jig saw puzzle pieces between the lids and base.The type 4 lid indicator 5, fig 23,is shown in section,and this section is taken across the centre and width of the lid,and divides the lid length tri' half.Two identical lids 55 and 55 cover the jig saw surface 27, arid each lid is fastened releasably to the base,using hook and loop fasteners 26.The lids include a top laminate 13,and a bottom laminate 15,and each laminate has circular ribs 40,and support pad surfaces 57 and 58,and the laminates are assembled together by method A as used with lid typesl,2 and 3.The top and bottom laminates are loosely fitted together appart from their rims,and the rims are glued to the corresponding laminate member.To utilise the lids for trapping the puzzle pieces 33, the two lids 55 and55,are placed over the jig saw pieces 33, and also fastened to the base,and the pressure pad 35 comes into contact with the puzzle pieces. 18.

Fig 45,shows a section drawing of the type 4 lids,with the lids in place on the base,and covering the whole of the jig saw puzzle construction surface 27,and the lids are 55,and are fastened to the base l,ind 1 by locating the lids,side by side and inside the base cavity wall 29,and securing them to the base using hook arid loop fasteners 26.Both the lid sections 55,are taken through the centre of the lids bottom laminate 15,and expose the wall section 68,which ts part of the circular ribs 44 and the section is also taken through the centre,of the thickness or depth of the lid bottom laminate 15.Indicator 69,shows the lid inside surface of the circular support pads and these are shown in figs 23 and 45There are also clearance gaps 70,and these gaps exist between the sides of the two lids and between the lids remaining sides and the cavity wall 29, and the purpose of the clearance gap is to enable the lids to locate easily within the base cavity wall, and onto the base jig saw puzzle construction surface 27.The centre of each of the two lids 55,is in allignment with the centre of each half of surface 27,and to trap the puzzle pieces 33,between the lids circular support surfaces 35,and the dome shaped surface 27, pressure is applied to the puzzle pieces,and the circular pressure pads are flexible enough to adjust to the required shape or configuration needed to trap the individual puzzle pieces,or the assembly of puzzle pieces.The circular prssure pads comprise of various diameter rings with the smaller spigot in the centre of the lid and then the remaining support pads increase in diameter arid encompass the inner diameter ring, or each pressurepad ring increases subsequently in diameter.

The circular ribs are 44,fig 23,and the circular ribs form the inner and outer diameter of the pressure pad contact surface 35, and fig 46, illustrates part of the mechanical function,which is utilised in the type 4,lid,in order to trap the puzzle pieces onto the baseFirstly the diagram shows the top and bottom lid laminates,and the base construction surf ace, and in this drawing there are no puzzle pieces in between the lid and the base, and there are no puzzle pieces,because the relationship betwwen the functional shape of the lids,inrelation to the shape of the base can best be illustrated without the puzzle piecesln fig 46 a partial enlarged section view of the tupe 4 lid and type 1, base are shown and the following features are illustrated, 35,are the pressure pad surf aces,and these are circular, and caine into contact with the surface 27,via the circular corner radius 6l,but starting from the central spigot 64,which is in contact with surface 27, and on contact becomes curved shaped 63,if progression is then made outwardly it can be seen that the corner radius 61,is also in contact with the surface 27,and the contact point is 71,however for the spigot to be in contact and the corner raddii 61,to be in contact at the same time, the contact surfaces 57,and 58 fig 23,need to flex and become angular as shown in fig 46.If progression is again madeoutwardly the corner radius 61 can be in contact on every circular pad or ring then all the interconnecting contact surfaces 57 and 58, will flex and become angular,however when the central spigot ist contact and all the circular pads are in contact it proves that the lids can trap any puzzle piece no matter where it is placed on the surface 27,and so if one puzzle piece was inserted in between the lid and base,and then the lid was fully secured to the base,the circular pad that traps the piece would tilt at an angle in relation to the other rings,however if the surfaces 57 and 58 had limited flexibility it is very likely that some of the other circular pads woul also tilt,but these would probably not tilt as much as the pad which is securing the puzzle piece.If more puzzle pieces were placed in different positions on the base, then several of the rings woul tilt at the same angle,and again each circular pad would trap the corresponding puzzle piece onto the base,and a further

description of fig 46 is as follows.

The series of pressure pad rings in each lid,come into contact with the dome shaped surface 27,and this feature is illustrated in fig 46,where the jig saw pieces have been removed,and as shown the central spigot 64, and pressure pad 35,form to the dome shape base,and on pressing the lid down further the corner radii 6l,oi' the circular pads,comes into contact with the dome shaped construction surface 27,and gap 62,shows the height difference between the spigot 64,and the corner support pad radii 6l,and as the lid is pressed down further each corner radius of each outer consecutive ring or circular pad will 20.

come into contact with surface 27,the corner radii 61 inscribe the circular pressure pad to which it belongs.The circular pads provide an excellent mating surface for the dome shaped surface 27,arid the whole circumference of radius 61 will come into contact with the whole of the dome radius matching circumference and this match of course will apply to all the circular rings or circular pressure pads 35. On construction of the puzzle, the puzzle pieces will prevent contact between the lid contact pads and the base,and each circular pad can operate on a different plane, level or height,and if there is only one jig saw piece under a particular circular pad this can cause the pad to tilt,with one side of the ring trapping the puzzle piece and the opposite side of the same ring,pressing onto surface 27, so there should be enough flexibility in the circular pads to accornodate the puzzle pieces in whichever position they are situated on the construction surface 27,and the various circular pads can tilt at different angles relative to each other and still function well in trapping the puzzle pieces.The pressure pad surface 35,is a flat surface,and all the circular pads collectively that are on the lids form a flat plane,but flex on contact with the jig saw piecesand the jig saw pieces will in turn flex on contact with the puzzle surface 27,and a combination of flexible pads and flexible jig saw pieces will provide sufficient configurational pressure between the lids the puzzle pieces and the base to hold the pieces secure.

The type 5 lid 6,figs 24,35,36,41 and 42 provide another mechanical means for trapping the puzzle pieces between the lids and base,the type 5 lids comprise of a top laminate 13 fig 24 and a bottom laminate 16 fig 24,and the two laminates include a top laminate which incorporates circular pressure pads 35, and which are identical in shape to the circular pads in types to lid types 1 to 4,but the bottom laminate is just a single layer of plastic l6,that is seperated from the top laminate by a cushion of air 65,fig 24,and fig 24 shows the type 5 lid assembly.In this type of lid,the bottom laminate pressure pad surface is flat or slightly undulating,and comes into contact with the puzzle pieces 33,however to secure the puzzle pieces firmly onto the base the lid is pressed down onto the base and the flat pressure pad surface 35,becomes concave as shown 21.

in fig 36,but the concave pressure pad does not become truly concave or forms a full concave curve until the lid is trapping a fully assembled jig saw,with the jig saw forming to the dome shape construction surface 27,and in turn the secured lid forms over the dome shaped top surface of the jig saw puzzle,and in turn the lid pressure pad becomes a dome shaped concave curve.So when the lid is pressed firmly onto the base the pressure pad surfaces 35,become taut,which takes up the slack of the undulating surface,and the more puzzle pieces that are assembled causes the lid to become more taut,and as the lid bottom laminate bottom layer becomes more taut it becomes more stiff.A combination of the taut layer 66,and the cushion of air 65,helps the surface 35,to adjust to the configuration needed to trap the puzzle pieces to the base.The taut surface 35,can adjust to many varying concave shaped areas of the layer 66, and the concave shape depends on where the jig saw pieces are situated on the base and how many pieces there are and whether some of them are assembled together,which would result in dome shaped areas of jig saw puzzle,and in different position on the base.In fig 36,the taut layer has become curved shaped and traps the puzzle pieces 33.In fig 41 the layer 66 has become curved onto the jig saw piece top surface,but the layer 66, surrounding the trapped pieces is more flat shaped.In fig 42 the layer 66 is shown trapping the two puzzle pieces 33,and in between the pieces the layer 66,is again quite flat.It is clear that the flat layer 66,on becoming taut can change into curved,.flat,undulating and dome shaped surfaces.and other shapes, In lid type 6,fig 25,a cushion of air exists in between the top laminate 17,and the bottom laminate 18,and circular ribs and pressure pads exist in both top and bottom laminates.The circular pressure pads 35,will adapt to the dome shaped construction surface and the puzzle piece varying shapes by utilising the trapping mechanism mentioned for lids types I to 6.The cushion of air between lid laminates top and bottom members on lid types 5 and 6,is useful,because the cusshion of air creates resistance between the top and bottom laminate mernbers,which in turn creates a more suitable pressure for trapping the pieces between the lids and base.and the varying 22.

air pressures in between the lids and base will enable varying a-iipressure between the lid and the jig saw pieces,and the jig saw pieces and the base.

The type 8 lid is quite different from all the other lids in the fact that the lid top is concave shaped,and the reason for this is,that when the flat pressure pad circular surfaces 35,trap the puzzle pieces onto the base,the pressure pad plane becomes a concave dome shape,and the lid top surface 67,will become flat.as shown in fig 28.The concave dome shape 67, fig 27,is made the same size radius dome as the surface 27.

On packaging the hoilder lids can be fitted to the base, which in turn will provide a flat,holder top surface,which of course makes packaging cheaper and easier.

The base and the various lids in this jig saw holcer patent, can be made from plastic,wood metal,fibre,cardboarcl and other materials,and if plastic is used,the plastic can be transparent or translucent,and possibly opague,or the plastic can be non transparent Figs 43,and 44. show a puzzle cont--act pressure pad that includes spherical shaped domes or raised dimples 56, and the protruding sphere shapes or curved protrusions are spaced at regular intervals on the pressure pad surf ace. The raised spheres 56,may help to trap the puzzle pieces better, than just having the normal flat planed or dome shaped pressure pads 35,and the reason they may work better is that the puzzle pieces 33,may tilt when trapped by a raised sphere protrusion, and the tilting action of the puzzle piece would result in the puzzle piece edges being lifted off the surface 27,and the lifted edge,and puzzle piece could be prevented from sliding by catching,or touching,the surface of one of the nearby raised sphere edges or domes,and this action is illustrated in fig 44,and the puzzle piece ref fered to is piece 72,which is the tilted puzzle piece.It can be safely assumed that if the surface of one of the raised protrusions 56,were to trap the puzzle piece 33,on its centre,then all the piece edges would be lifted off the surface 27,which would mean that more pieces could catch on the sides of more raised domes,which could mean that more pieces could be efficiently trapped.Fig 43,shows the central puzzle piece being trapped on its centre,and as can 23.

be seen,all the perimeter edges of the piece 33,are lifted off the base. In fig 43,there is a cushion of air in between the lid top lamina-te,and the lid bottom laminate,and in fig 44,the top and and bottom laminates are adjacent to each other.

The dotted areas in figs 3,5,11,12 and 20,represent or show the contact areas,which connect the lid laminates together, or the base laminates together,however the dotted areas shown in figs 12 and 20 are the contact areas that,come into contact with the puzzle pieces,and trap them onto the base.

The dotted areas in fig ll,are on the underside of the lid and the dotted circular support pads come into contact with the lid tops in types,l,2,3, 4,7 and 8The support pads,support the lid tops.The cris crosses in figs 1, 10,12 and 20,and these represent the hook and loop fasteners.

To fasten lid types 4,5,6 and 7 to the base member,hook and loop fasteners are utilised,with the hooks or loops being attached the underside of the lid,and the corresponding or cooperable hook and ioop fasteners being attached to the pockets or cavities set into the construction surface 27.

The jig saw puzzle construction surface 27,figs 1,10,14,19, 21,22 and 28,ls formed by a curve,and the curved surface 27, is a uniform curve,and the curve has been struck from the same radius point,so that any point on surface 27,would be equidistant from the radius reference point.In the previous pages of this patent,the surface 27,has been described as dome shaped,but this description is innacurate,as a dome shaped object could be likened to a hemisphere,and a hemisphere is equal to one half of a complete sphere,which looks nothing like the jig saw board surface.The one feature that a dome shape could have in common with surface 27,is that the dome could have the same uniform curve or a different size u.crtmLIcurve The feature that surface 27,and the curve on a dome could have in common is that the curved surface on them both could be created in the same way or by the same rnethod,and the uniform surface is that of a partial sphere surf ace.A further feature mentioned in this patent,is feature 56,whlch is described as a spherical protrusion,and although the curved protrusion could have a uniform curved surf ace,the protruding surface 24.

could be of various shapes,such as pointed,ridge shaped, spheroidal or other protruding and suitable shapes. The surface 27 is a convex curve, but surface 27,could be formed in the same way as the convex curve,but made concave,so that the jig saw puzzle can be constructed on a concave surface, but still having the same shaped curve as a partial sphere surface.Both the concave and convex surfaces can be undulating, but still be concave or convex surfaces,and the undulations can form different or multiple curved surfaces,but would still trap the puzzle pieces,and the concave and convex surfaces can also be used for the lids pressure pad and support pad surfaces - The base bottomn,top surf ace 23,would also need to be convex or concave, on the case bottom upper surface 23,and the concave or convex surface would of course support the surface 22, which is the underside surface of the puzzle construction members The various lid underside surfaces,which are the pressure pad surfaces could also be convex or concave.The circular support pads ref fered to in this patent can also be support surfaces or circular contact surfaces. All the base and tIc members can be made Irom materta that is trans.Lucent,opaque or transparentivIateridl can ne held n ueteen the top and bottom base members and inbetween the top and bottom lid rnembers,and this material can be seen through the base and lid transparent members ana provides decorative appeai The decorative material can be mace trom paper,cloth, cardboard,plani rnaterial,metal,plastic, leather or suede, recycled material, crystal, parnt,varnish, powder, sand, rock grains, gold leaf,foam,sponge,pot, ceramnlcs,glass,vood,biological plant material,siik, ibre,pig oristle, horsellair,fur,skin,hair, shell,rubber,polystyrene,felt,coral,mocher of peari,coal, cement,pLant fibre, leaves, graphite,bakalite,porcelain, carbon materials,fish scale,water or other liquids can be used if the top and bottom ha and base members are sealed together and made waterproof. The lid and base members can also be made from marble or graphIte. The internal decorative materials can also be used as external decorative materials, and oil based materials can be used for these,also wax can be used.The decorative material used and situated in the spaces inside the base member or membersand inside the lid member or menibers,can be made from any elements or materials,or any elements or materials suitable for their purpose. Decorative materials can also be used on the outside surfaces of the jig saw puzzle holder surfaces,and these can also be made from any elemelements or materials.The base and lid members can be made from any type of metal and the base and lids can be formed by pressing the metal into the required shape.The puzzle holder -lid or lids can be fitted to the base via a connecting hinge, with the hinge being formed by pressing a tool into the lid and base to create recesses and appertures into a shape suitaiLe for accepting a length of wire or rod,which interlink the lid or lids,with the base member,to form part of the interconnecting lid and base members,and the hinge mechanism allows the holde! lilid or lids to close onto the base member and trapping the puzzle pieces onto the jig saw base.

The hinge mechanisir that interconnects the lid or lids to the base can be made in two parts or more,exoluding the connecting wire or rod.Part of the hinge is incorporated into the lid and the remaining hinge part is incorporated into the base, member or members.The hinge part incorporated into the lid is formed into the lid material,and therefore the lid and hinge can be made from the same piece of material,and this method of forming the hinge also applies to the jig saw base member or members,with the base and hinge being made from the same piece of of material. Magnetic strips or pieces can be used to hold the puzzle holder lid to the holder base,and trapping the puzzle pieces inbetween the lid and the base,and these magnetic parts can be used or incorporated into any jig saw puzzle holder whatsoever,or any jig saw puzzle holder that exists or may exist in the future. The magnetic strips or pieces can be situated any where inside the holder lid and base members,or anywhere outside the lid and base members,with the magnetic poles of the magnetic parts being arranged so that the lid and base members are held together by attracting magnetic poles.Usually opposite poles attract such as North and South and magnets with these poles can be fitted to the holder or any types of magnets,and magnets with any types of poles.

The jig saw holders mentioned in this patent and any of their accessories can be made from any elements or any suitable materials,and any mechanical or other features mentioned in this patent can be incorporated into other designs of puzzle holder.

Both the lid and base surfaces used for trapping the puzzle pieces can be formed in a sphere shaped surface. The sphere shaped surfaces can be convex or concave,but in order to trap the puzzle pieces inbetween the lid and holder base the convex or concave surfaces of the lid and lids or base need to match up or correspond to each other.If the base is a convex shaped puzzle construction surf ace,then the corresponding lid or lids shape would need to be concave in order for the base to fit to the lids, or if the base puzzle construction surface is concave then the corresponding lid or lids would need to be convex in order to trap the puzzle pieces. The radius that forms the spheres on both the lid and base members can be any size,however in order to trap the pieces t-he curve radius on the lids or base would need to vary by the thickness of the jig saw pieces being used,f or instance lets say that the base.

puzzle construction surface is a 25 metre spherical surface and concave, then the spherical radius size of the lids would be the 25 metre radius of the concave base,minus the puzzle piece pieces thickness which could be l5 mm meters,giving a lid convex outside spherical surface of 24 metres and 9985 mm, and this difference in the lid and base surfaces that the puzzle pieces are trapped between would be a gap of l' 5 mm, which would hold the pieces lightly in place,however if more pressure is required to hold the pieces in place then the lid and base corresponding surfaces can vary to whatever size radius is needed in order to hold the pieces more securely.The lid or lids and base puzzle securing or trapping surfaces can be of multiple or varying convex and concave surfaces on each lid or base puzzle contact surfaces.The multiple and varying convex and concave surfaces can be a mixture of curves on the lid or base, meaning,there can be several different sizes of curves on one base surface and on one lid or lids surface. The area formula used to form a sphere is 4tT r The puzzle construction width and length of the base and' lid is 1 metre by point 8 metres,but the lid and base can be any suitable size.

Any kind of fastening mechanism can be used to fasten the lids to to the base including the detachable mechanisms mentioned in thLs this patent such as magnetic pieces and velcro The expression detachable mechanisms, meaflS mechanisms that allow the lids to be detachably fastened to the base.

The Jig saw Holder lid and base members mentioned in this patent are made from plastic or metal but can be made from any other elements or materials. 2.
