Abstract

The tightest orientation of slabs and beams as achieved by PCT/SG2010/000092 is 75 degrees and is now surpassed by the introduction of further elements that can achieve angles of 20 degrees and even lower if required and there are choices to endow wall structures to tight corners. Bricks exhibiting curved edges have been explored further and one of the areas being, the ability to erect structures that employ gradients without leaving unnecessary gaps, with elements that are interchangeable for other general use. The other area being the ability to cover adequately, in a systematic way, a non¬ linear wall structure with a roof property that blends in with the construction system. In the overall the objective of this application is to expand the possibilities of connecting options by combining the elements as disclosed by the prior art and the improvements and variations described by this application, thus enhancing the operation of the said CONSTRUCTION SYSTEM to deliver a more compact result in terms of physical structure as well as higher resolution in terms of visual impact.

Description

IMPROVEMENTS TO A CONSTRUCTION SYSTEM

TECHNICAL FIELD

This application pertains to a toy modeling system that is to be seen with reference to my earlier application, PCT/SG2010/000092 dated 15 March 2010 that describes the basic operation of building blocks that connect at varying angles. The present application serves to introduce additional elements and specify their individual characteristics that are meant to work in conjunction with those primary elements disclosed by PCT/SG2010/000092. This can also be seen as a continuation to my said earlier application. The objective of this application is to expand the possibilities of connecting options by combining the elements as disclosed earlier and the elements introduced hereafter, thus enhancing the operation of the said CONSTRUCTION SYSTEM and thereby teaching a method that steers away from both straight edge bricks and repetitive usage of primary elements of a single pattern. The improvements detailed by this application are subjects of my SINGAPORE PATENT APPLICATIONS, bearing the numbers 201006489-7, 201 101057-6 & 201 103326-3 filed on 06 September 2010, 14 February 201 1 & 10 May 20 respectively.

BACKGROUND ART

Throughout this description, the matter detailed by PCT/SG2010/000092 would be referred to as 'prior art' and the said document itself will be referred to as 'prior application'. Firstly the primary elements as in the prior application will be mentioned briefly for reference purposes. Dimensions that are to be employed by slabs and beams will be described. Further to this, some variations that can be employed by primary elements in comparison to my prior application will also be described and the said variations falling within the scope of the said prior application's matter. The variations are described to such extent, for the preferred embodiments to be understood to have, certain aspects that are not and other characteristics that are to be the emphasis for protection sought by this application and the said aspects and characteristics to be distinguished from each other.

The unit of measurement used will be millimeters (mm). Dimensions are mentioned in certain aspects of the preferred embodiments to facilitate the presentation of this application. Dimensions stated do not limit the said aspect referred to, by the said numerals.

Curves that shape the elements take reference from a 16mm diameter of the connector eye but may vary when necessary ( in relation to curves outlining second portions of corner walls and also in relation to passageways made in beams or slabs ), and said variations will be related to the said base 16mm and referred by the term 'base radius'. Linear dimensions in relation to lengths and widths will adopt integer multiples of 4mm, referred as a 'base length', as is to be employed by the preferred embodiments.

There is a parameter 'thickness' as mentioned and substantiated in the amendments to PCT/SG2010/000092 pointing to the said 'thickness' to be equivalent to the dimension employed by the outermost diameter of the cylindrical end of a typical slab and as such the said parameter to be 16mm, as employed by the preferred embodiment throughout this document.

The term 'material management' is used to refer to spaces created in individual elements for purposes that are 'not a subject' of this or my prior application. Such passageways would observe an allowance of a clear 1.5mm all round whereby 'allowance' refers to the presence of material and by which combination a certain level of resilient character will be experienced by the element or a particular portion of an element in concern. The thickness of a slab or beam as in the prior art is to be taken as 16mm. The outer diameter of a connector eye or in other words the cylindrical side of a slab or the circular portion of a beam is also to be 16mm. Thus the concave side of a slab defined by 8mm radius and the said dimension applying to beams similarly, which are derivatives of the cross section of slabs. Slabs were defined by the prior application in a plurality of widths and further to that, it is now presented in multiples of 4mm, and the same would apply lengthwise for slabs and lengthwise for beams. Beams employ a constant width of 1 6mm, which would translate to 8mm at each end ( lengthwise ) as denoted by the distances 15 to 16 and 17 to 18 in Fig 2E. The 8mm width of connector eyes for beams would justify double the said distance, 16mm length to be employed by connecting studs when the extreme ends of their grooves are taken as a reference. This would mean a connecting stud without non- grooved extensions would be completely flushed within the domain of adjoining beams' connector eyes, leaving no protruding section. The slabs' connector eyes will exhibit grooves that reach 8mm along the width that is inclusive of an ideal countersunk allowance, and all connector eyes with regard to this system are meant to individually accommodate half of the length of any connecting stud, disregarding the non-grooved extensions that individual studs can exhibit,

The minimum width of a slab is to be 8mm, whereby the total width of the cylindrical side will be utilized by a countersunk allowance at each entry and rotation arresting grooves in between. Slabs that exceed 16mm width will exhibit a smooth non-grooved passageway linking the deepest points of the connector eyes that permits a see thru, and the said passageway defined by a radius that is equal to the radius of a connecting stud that - disregarding the stopper of the said stud - has its rotation arresting grooves subtracted.

An example of a stud with its rotation arresting grooves subtracted is depicted by Figs. 2B1 and 2B2. Such non-grooved studs with null orientation structure can be used by this construction system in 3 variants, which are (1 ) 24mm length with an extension on one side for alignment with a third element as in Fig 2B, (2) 32mm length with extensions to both sides for alignment with an additional fourth element and (3) 16mm for a typical alignment of 2 elements. The null connectors would apply at situations when a first element has already been fixed at a required angle and the intended adjoining element is to follow the orientation of the first element.

Variations that are clearly visible from Figs 3A to 4H in relation to prior application are the connector eyes and the passageways 93 and 100. The intended inner radius of connector eyes, the radius employed by and the depth of the countersunk allowance or the intended number of grooves and their teeth dimensions are subjects of neither the earlier nor the present application. Thus, a visibly different connector eye is exhibited in Fig 2C and thereafter, which is only to be taken as one among the preferred embodiments. A third version of connector eyes is used by the Figures in Drawing Pages 21 to 30. As for passageways indicated by 93 and 100, they are variations from the beam depicted by the prior art and will be a subject of this application as the shape is designed to accommodate the penetrating second portion of Element (B) as described in the forthcoming text.

The connecting stud exhibited by this application is proportionately larger in relation to the prior application, but the functions are the same. The absolute dimensions of the stud are not subjects of both the prior art and the present application. The connector eyes have been depicted in different configurations when taken against the prior application. The present application does not sought protection for the way the connector eye is configured, thus a visibly different groove-teeth arrangement will be exhibited when different sections of this description are compared against one another without affecting the subject matter of this present application. Variants of connector eye configurations have been retained in drawings to relate to particular disclosures with regards to priority dates.

Furthermore, connector eyes may be represented in certain figures by a plain circular portion indicated with the number ( 88 ). In such instances it should be understood as a connector eye being present and the omission of details is deliberate, as to reduce the complexity of the diagram.

SUMMARY OF THE INVENTION

The following description would define from a functional point of view, the different elements and their ability to connect in various ways to physically construct wall configurations and other structural features that are not achievable by the prior art. The first section introduces corner elements that are able to connect at acute angles tighter than 75 degrees, and thereafter all the way down to 20 degrees an below. The prior art as depicted in Fig. 1A, is limited to achieving just 15 degrees lesser than a perpendicular connection at the maximum or its tightest orientation, when 2 adjoining elements are taken as subjects, brought about by a first element utilizing the cleft of the second element. It is important to note at this point, that the characteristic cleft is not a feature of the elements introduced hereafter as corner beams, which will be described by Section One. Apart from these corner beams, other elements would be introduced, that may again feature the characteristic cleft. The new elements introduced by Section One are (A) corner beam hereafter referred also as Element (A), (B) corner wall hereafter referred also as Element (B), (C) axial switch coupling and (D) extendible corner beam coupling. Elements (A), (B) and (C) have been uniquely identified as referring to specific physical entities but, Element (D) is a function delivered, as it is a variant of corner beams and a variant of corner walls combined to do a task that results in another element. Element (A) a twin eye comer beam should be understood as a typical corner beam. Element (B) corner wall, a trapezoidal derivative as in Row 6 of the array of elements should be understood as a typical corner wall. Element (D) is comprised of two open end corner beams as in Rows 2 and 5 of the array of elements and further to that a corner wall can be any one of the elements marked as 103, 104, 105 or 106. Row 7 of the said array depicts another variant of a corner wall that is a derivative of exploding the Origin' slab as in Drawing Page 19 marked by 7'.

The second section of the description of this application will again relate to elements as described in Section One, whereby the emphasis will be placed on the derivation of the said elements and also to describe the variations that the said elements can exhibit in comparison to the stated matters in the first section.

The third section of this description relates to 2 different elements whereby, the first element facilitates the blending in of corner slabs that involve a slope, and the said corner slab achieving a smooth gapless transition relevant to adjoining slabs or beams and further to that, also conforming to the applied 'base' configuration that uses dimensions in multiples of 4mm.

The other element described by the third section serves to endow a roof property to wall structures that do not observe a right angled corner or those that are not of linear disposition, while maintaining a systematic method of transfer, as typical slabs introduced by the prior art would not be adequate to close up an irregularly presented wall structure with a roof without leaving inevitable gaps. The objective of such elements - termed as corner surface components - is to provide a crucial mechanical 'switch' that blends with the system and the rest to be determined by the creative work of the individual builder. In total, when the elements defined by the three sub-sections of the forthcoming description and extended further by the scope of the variations employed as components available to the construction system, which is based on my earlier application are utilized as a build and play toy, the resulting product will exhibit features which will substantially change the structural capabilities of toys that have based themselves on straight edge principles. Build and play toys have two main objectives, that is of recreating an intended structure and at the same time adequately satisfy the builder in the field of visual art. Frequently the two are compromised by the sheer inadequacies of the primary element itself. The following text teaches how the primary elements can adopt different characters and deliver different functions when they are based on a basic block that has both straight and curved features by which, at every step of building an intended structure the individual builder will be equipped with the ability to make finer ( more pronounced ) features when compared to straight edge bricks, thus clearly steering away from visual results that are pixel-formatted.

DESCRIPTION OF PRESENT INVENTION

Section One

Firstly, Element (A) corner beams, will serve as interconnecting beams, similar as in prior art, thus connector eye being a feature at each end lengthwise. Element (A) is to be understood in a plurality of lengths and said lengths to be in multiples of 4mm but width to be a constant of 1.6mm. The thickness of beams and slabs as taught by the prior art is to be equal to the diameter of the cylindrical portion of the slab which is 16mm, which is also the outer diameter of any beam's connector eye. This application differs, and emphasizes that the thickness of (A) to be only half of the diameter when the circular portion of the beam is taken as a reference, thus 8mm. Thickness of a corner beam is the distance 48 to 49 and diameter of the circular portion of the said beam is the distance 46 to 47 as indicated in Fig. 3B.

The side view of a corner beam would be of the shape as depicted by Fig. 3B and a front view of the same element will be as in Fig. 3C. A twin configuration as seen in Figs. 4A to 4D would show how this element is to function. An open (Fig. 4B) and a closed (Fig.4A) positioning of a first and a second similar length corner beam are exhibited. Element (A) permits a positioning as in Fig. 4A as it employs such a thickness as prescribed by the preceding paragraph, thus a result not achievable by the prior art. The portion of the beam, which determines its length, hereafter referred as second portion of corner beam, can exhibit passageways as indicated by 93 ( not limited to single pattern ). These passageways have purposes, which is firstly to accommodate the penetrating second portion of corner wall and the other is material management. As for relatively longer corner beams more than one passageway is a possibility as in Figs. 4F and 4G and further depicted by Row 4 in the array of elements.

Element (B) corner wall s responsible for endowing surface area to outlines created by the corner beams when required. Element (A) and Element (B) can be understood as individual functional parts when a slab is exploded into logical segments. The main purpose of the corner wall is to deliver an adjoining element with surface area in situations that would deter the use of a slab when taken in comparison to the prior art. Element (B) can be defined as having a first and a second portion. As seen in the leftmost section of Fig. 5A, it has a first portion that is defined as the surface area 61 and from a side view, as in the rightmost section of the said Figure, it employs a constant thickness of 8mm that is the distance 62 to 63, that is to be equivalent to the thickness of corner beams but to be presented in a plurality of lengths and widths. Corner walls are generally trapezoidal in shape, that is from a side view as in the rightmost sections with regard to Figs. 5A to 5C. This is due to the curvature based construction system, which presents, as one of its common junctions, a beam ending with a connector eye as an adjoining element. The. plurality of lengths and widths will further define the plurality of surface area that corner walls can represent as depicted by the leftmost portions of Figs 5A to 5C by 61 , 64 and 65 respectively.

The second portion of corner wall refers to one or more protrusion/s from the first portion that serve as the penetrating part that effects a connection with an adjoining element shown as 95 ( not limited to a single pattern ) in Figs 5A to 5C. The said second portion can be defined as a linear extrusion of at least one closed curve originating from either or both of the two flat surfaces of the corner wall, and the resulting protrusion/s to exhibit a thickness that is to be lesser than the corner wall's thickness. The thickness of the second portion can be ideally 5mm. Rows 6 and 7 of the array of elements show multiple variants and dimensions of corner walls. The penetrating second portion of the corner walls is to be understood in general as protrusion/s of a trapezoidal shape but incorporating curvatures and to be features of either or both sides of a corner wall and to feature in a singular or plural fashion ( on a chosen side of a chosen corner wall ) in a linear arrangement along the length of the subjected corner wall. For presentation purposes all corner walls depicted in this application have second portions on a single side only ( with exceptions made for Figs. 12H1 and 12H2 ).

Any passageway meant for material management in a corner wall is the space that is derived from the linear projection of an outline which takes the flat surface of the said corner wall as its origin ( on the corresponding opposite side of the said corner wall's second portion when the said corner wall has a second portion on a single side only ) after at least a clear 1 .5mm has been given all round for material strength. All round should be taken to mean as from the side view of the corner wall in concern. Thus, the thickness of the second portion of any corner wall can be ideally 5mm, but the number of protrusions still dependent on the particular dimension of the selected corner wall.

Length of corner beams determine the length of corner walls required, thus the length of corner walls would be defined in multiples of 4mm also, conforming with the rest of the construction system. Although a simple plug in mechanism, the corner wall has been described and depicted to this extent to exemplify the methods of building gapless wall structures within this system when trapezoidal sections of varying lengths are presented or when curvature ended elements are employed by the said construction system. The third Element (C) is axial switch coupling. Up to this point, the prior art solution to connection of slabs and beams have been effected by a convex edge contacting a concave edge and pivoting one in relation to the other to achieve the desired result. The axial switch coupling, as termed by its function, refers to a 2 member element designed to work in conjunction to bring about a connection that is able to switch the axis of the pivot of an adjoining element by endowing a flat portion with the character to deliver a pivotal connection and in the alternative a curved portion to deliver a flat surface of a beam or slab for further connecting options.

The side view of a first member of Element (C) is shown in Figs. 6C and 6D, and it is to be noted of the presence of the characteristic cleft as described by the prior art. The 2 extensions marked 51 and 52 are resilient structures that are designed to function like a clip that allows the first member as in Figs. 6A and 6B to snap into positions to a second member as exhibited in Figs. 6G and 6H respectively. The first member can be defined as having a first portion that serves as a connector eye with an adjacent cleft and a second portion as defined to be the resilient structure. The width of any Element (C)'s first member need be only 8mm or 16mm.

The resilient second portion should be taken as 8mm or 16mm in length, which are the respective distances that represent the minimum width of a slab or the minimum width of a beam. The minimum width of a slab and beam are being mentioned, as the first member is designed in variations to snap into a perpendicular orientation to either of the derivatives of the said 2 primary elements with regards to the prior art. The 2 variants of the first member are as shown by Figs. 6A and 6B. Even though the axial switch coupling's function can be clearly understood by the first member, its function is not complete without the second member, which is the molded structure that accommodates the resilient second portion of a first member in a snapped on resting position. Each variant of the first member of Element (C) will define a second member, thus 2 variants of the first member defining 2 variants of the second member.

There is a third variant in the second member of Element (C), which is the difference depicted by Figs. 7A and 7B that allow for a linear transfer that helps retain alignment as depicted and described by Figs. 7E to 7H. The difference in the placement of the receiving allowance in the second member is described with reference to the drawings. Element (C) and its variants do not exhibit passageways as opposed to typical slabs, beams or corner beams so as to allow maximum material strength.

Element (D) extendible corner beam coupling is the fourth element, and it will be presented as a set of three members for the purpose of description. The first and second members are similar opened end corner beams ( Opened' as referring to the absence of a connector eye at a relevant end ) as shown in multiple views by Figs. 8A to 8C and they are shown placed in a linear fashion as in Figs. 8D to 8F completing a visual set up of an elongated corner beam. Similar to corner walls, the length of opened end corner beams is defined in multiples of 4mm. The concave and convex edge of the alternate halves of the width of any first opened end corner beam share the same radius such that when a second opened end corner beam of any length is flipped and placed in an orientation as in Fig. 8E, the gaps between the two said beams is closed and a set of passageways 100 is presented for the connector 103 or the third member of Element (D) to complete the joint. The third member, corner beam connector 103 comes in to play as it is used to join the first two members as well as to present adjoining edge curves that cooperate with variants of Element (B) to blend into the system as in Fig. 9A to 9C.

The extendible corner beam coupling described by the preceding paragraphs should not be taken as limited to the particular form in which they are depicted by the diagrams. Whereas the function delivered by the twin opened end corner beams coupled with the connector 103, opens up a set / group of connectors to complement the various permutations and combinations of elements / second portions presented by the construction system as a whole, such that the individual builder is not limited to a single connector or restricted by options that are only open to either a convex / concave junction in the structural progress of an intended model. Thus Element (D) extendible corner beam couplings will be further explored by the next section of this description.

Section Two

Element (A) corner beam and Element (B) corner wall can be understood as individual functional parts when a slab is exploded or split into logical segments. The slab being referred to as Origin', does not involve or exhibit the characteristic cleft as stated in my prior application. The 'origin' slab, depicted by Fig 10A is of one of 40mm length and 1 6mm width. The dimension 40mm refers to the distance between the radial center of the distal ends ( lengthwise ) denoted by the distance ( 25 ) to ( 21 ) by the said Figure, being points relating to a single side of either of the distal surfaces that determine width of the said slab. When the said slab is exploded in particularly defined manners as outlined by Figs. 10B to 10C and 11 A to 11 C ( 10D and 11 D employing a less than 40mm length slab as an Origin' ), each segment derived would exhibit curves of similar radius ( 8mm as in the preferred embodiment ) at their distal ends ( lengthwise ), which can be convex or concave, that are meant to contact adjoining elements, or exhibit at least one surface that can be used as a connection point or at least one connecting eye that endows the said segment with, at least, one feature to become an adjoining member that can blend into the said construction system.

Element (A) as defined by Section One, would be the derivatives as depicted in the array of elements ( Drawing Pages 27 to 30 ), by Rows 2, 4 and 5. In the said array of elements, all corner beams inherit a width of 16mm, which is the width of the said Origin' slab. Element (B) can be defined as having a first and a second portion and is depicted by Rows 6 and 7 in the said array of elements. The first portion that is defined as the surface area, marked by ( 61 ) in the rightmost sections of Figs 5A to 5C, employs a constant thickness of 8mm, that is also equal to the thickness of corner beams, but taken to be presented in a plurality of lengths and widths. The plurality of lengths and widths of corner walls will further define the plurality of the surface area that can be taken up by the said element individually. In the array of elements all corner walls exhibit a width of 8mm only, regardless of the Origin' slab.

Corner walls are generally trapezoidal ( there are exceptions ) in shape from a side view but can also be featured in variations of mixed convex and concave ended structures as depicted by Row 7 ( Drawing pages 28 and 30 ) or twin convex ended (conical) structures. There is a need for such a convex end corner wall, as to be utilized as an adjoining element with the concave end of a trapezoidal corner wall. A corner wall featuring a twin convex ended structure is exhibited by the element 103 by Figs. 9A to 9C in Section One.

It should be reiterated at this point that comer walls' second portion are meant to work in conjunction with corner beams' passageways ( patterned holes marked 93, 100, 101 and 102 ) for the purpose of connecting to similarly patterned and calculated positioning of receiving sections of adjoining variations of Element (A) as well as Element (B). Multiple variants of corner walls and the positioning of their second portions are depicted in the array of elements.

The character of the outer curve employed (concave/convex) by a corner wall, will apply similarly on the curve that shapes the said element's second portion. It should be understood that the boundary of a given second portion is to be defined and hereafter referred as an inner curve ( 'inner' as in deeper towards the center of the surface of the said element as indicated by directional arrows in the left portion of Fig 12A5 ), from a side view, that leaves a border of 1 .5mm, at the least, in relation to an outer curve and the said outer curve to be defined and hereafter referred as the extents of the subjected corner wall from the said side view. Outer curves need not necessarily mean a larger radius value compared to its corresponding inner curve. Concave ended elements will experience an outer curve radius that is a step down ( smaller ) compared to their inner curve. Convex ended elements will experience an outer curve radius that is a step up ( greater ) compared to their inner curve. Length of corner walls would be defined in multiples of 4mm, which is to follow slabs, beams and corner beams employing the said multiples. Corner walls are to be employed in a plurality of widths by this construction system, as are the lengths. A 24mm length corner wall, as depicted by the array of elements ( width may vary when utilized elsewhere in Figures outside the array ) in Column 24 Row 6 and utilized in Figs. 12B1 and 12B2 with the marking ( 33 ) is the standard corner wa// that will be used extensively by this construction system, in the sense that the dimension employed by the said corner wall's second portion is in turn applied accordingly to all holed out sections to all variances and dimensions of corner beams, except for the smallest of corner beams, that is, a 20mm variant which is limited by its own said length.

With regard to Figs. 12B1 and 12B2 the different radii employed by the elements are evidenced. The outermost radius employed is 8.0mm ( also referred as the 'base' ) as in the elements marked ( 29 ), ( 30 ), ( 32 ) and ( 33 ), be it a concave or convex curve. If the sample of a 24mm corner wall ( 33 ) is taken, the outer radius of 8.0mm will give its second portion a radius of 9.5mm, sharing a radial center as the said outer radius, for this would be the appropriate value which will allow for the 1 .5mm spacing allowance all round.

Element ( 30 ) has a convex end and the 1 .5mm spacing requirement leads to a 6.5mm radius to be employed by the semi-circular second portion of the said element. This arrangement of situating second portions of corner walls with such spacing and employing such dimensions for both Elements (A) and (B) would result in each gapless joint of elements ( when contacting horizontally ), to exhibit ( at each element's end closest to the joint ) second portions' curves employing a radius 1 .5mm greater than the 'base' for one of the said second portion and the other to employ 1 .5mm lower than the said 'base'. This is depicted in Fig 12B2 by the element marked e104 effecting a gapless joint of elements ( 29 ) and ( 30 ), resulting in the radii markings ( at the area of the joint ) R6.5 on 30 , R8.0 at the line of joint and R9.5 on 29 .

Section Three - Part One

The first element described in this section is particularly designed to counter problems with regard to construction of corners, and step-up or step-down transfers, while maintaining a smooth blending with the other primary elements of this construction system.

The term 'split' is employed in this section to define the origin, plane and direction of extents ( boundaries ) of the subjected element, which would take its reference from an 'indicator', which in this case would be a line that is to define the limits of the particular element that is being described.

Note: The term 'split' should not be mistook as, the subjected element can be physically broken up to derive another or to transform into two elements. Deriving the corner slab coupling.

A twin concave end slab is depicted in an oblique angle in Fig 13A ( placed in an upright position ), and is again depicted in Figs Ί 3Β, 13C and 13D in 3 other different tilted ( pivoted ) positions, from a side view. All 3 said positions adopt the radial center (21 ) as the point of axis for each respective pivot as is denoted by said point in Fig 13A. Each of the 3 pivoted position is a function of the length of the chosen slab and the distance markers as corresponding to 3, M7 and M10 in Fig 14A. Each marker along the line ( 21 )( 29 ) in Fig 14A is placed at a distance that carries a value that is an integer multiple of 4mm away from point ( 21 ). Each pivoted position, will result in a substantially different angle as in Fig 14A and tabulated in Fig 14B, and this angle ( as suggested and taught by this application ) need not be of an integer value. As the distance marker is placed further the tilt compared to the marker immediately preceding a chosen first marker is greater as the distance the slab extends out with respect to the horizon increases as in relation to the arc denoted by ( 22 )( 23 ). With this we can substantially recreate certain common gradients used for structures with sloped walls by allowing the model to employ slopes that are determined by the formula presented by Figs 14A and 14B, which need not be a gradient of integer value, but importantly achieving sloped structures that conform to other dimensional properties of the system to provide a gapless blending in. The tabulated values showing the different angles can provide individual builders a range of values, whereby the most closest gradient can be chosen among the 9 different angles ( M2 to M10 ), which when employed as a corner slab coupling will also conform to the 4mm 'base length' used throughout the construction system.

The chosen slab 20 is shown by Fig 15A from a top view. A line ( L1 )( L2 ) is extended from the radial center ( 21 ) as in Fig 15B ( side view of element in Fig 15A ) which is at one distal end of the slab and it is extended perpendicular to the width ( W1 )( W2 ) of the said slab and shifted 8mm in a linear fashion along the width as depicted by Fig 15A to a second position, thus cutting thru point ( 22 ). The line is to be rotated, using the point ( 22 ) as the axis, by 45 degrees that is half of the corner angle that is to be constructed by the chosen corner slab coupling and the Origin' slab 20 to be split by the line ( 23 )( 24 ) employed at its last position. Line L1 L2 moved along the width of the slab becomes L3L4 and point 21 follows to become point 22, after which L3L4 is rotated and becomes line 2324 hereafter. The line 2324 is meant to indicate the reference that splits the said slab.

Employing the said splitting line and the slab maintained at the same said position when the split is effected, a selected first segment becomes the first element ( denoted with the suffix A in the Figures hereafter and up to Fig 20B for either of the 2 segments after splitting ) of a corner slab coupling. The other segment would be denoted with the suffix B in the Figures hereafter and up to Fig 20B ( the said segment which can also become the second element of a corner slab coupling ). The function of the corner slab coupling is delivered when either of the said 2 segments is rotated and the cut faces of the said 2 elements are brought together. The result will be a 90 degrees corner structure being achieved whereby it exhibits the chosen gradient with the absence of any gap and importantly conforming from a top view as in Figs 15A, 15B and 17E to the x and z axes ( adopting the axes from the Figures mentioned ) to the 4mm multiple that is employed as a dimensional property. The conformance to the said axes is similarly achieved when a corner slab coupling utilizes laterally inverted derivatives ( of itself ) as adjoining elements.

The distances from the radial center 21 to 25 or 21 to 21 or 25 to 25 ( relevant to the uncut faces of the slabs ), that can belong to one segment or can also relate to a point on the other coupling segment, will be an integer value that is a multiple of 4mm, the said multiple being a requirement for blending into this construction system. Such a configuration will provide a smooth transition of curved elements to slope outwards or inwards to continue on the structural progress of a model, eliminating gaps that can arise when structuring corners during modeling. The connector eye is situated at a mid distant when the length of the slab ( distance 2125 ) is taken as a reference. The pair of cut slabs will be fastened to each other by employing the connector eyes and a special angled stud 27 that corresponds to the angle created by the corner slab coupling and to be utilized as depicted by Figs 18A, 19A, 19C and 19E. The said

also employ a configuration that allows it to mate with the rest of the construction system.

Further to that, if one of the 2 elements of our corner slab coupling is rotated from a side view by 180 degrees and the cut faces of the 2 elements are brought together without a gap as in Figs 19B, 19D and 19F, a typical twin concave end slab is derived, which only differs by the fact that it is derived by 2 segments brought together as opposed to a single molded piece. They would also exhibit options for them to be fastened to each other with a typical linear connector stud 28 as in Figs 19B, 19D and 19F that can mate with the rest of the construction system. The significance of the corner slab coupling lies in the fact that a corner slope ( one which can be termed as special disposition ) is effectively brought about by an element that can also be utilized as a primary element without conflict with the dimensional properties of the construction system, thus allowing interchangeability, which is important for build and play toys.

Section Three - Part Two

The second element described in this section is particularly designed to attend to new problems brought about by a curve based construction system that has a tendency to present non-linear wall structures, thus a solution required to allow for smooth blend-in of adjoining components to complete an intended structure. Such an element allows the user to substantially recreate a cover or roof property to a wall section or perimeter that is presented in a non-linear or non- perpendicular configuration.

Corner-surface components.

A typical corner surface component can be defined as having a first and a second portion, when said 2 portions belong to one moulded element. The first portion is to be understood to employ the properties and variations of a typical corner beam, which is comprised of a single / twin connector eye and a beam portion that employs a thickness that is half the value of the outermost diameter of the connector eye but the length determining beam portion's width will be equivalent to the connector eye's width.

The second portion is to be understood as a flat protrusion perpendicular to the width reference of the beam portion. The protrusion is of uniform thickness and the said thickness to employ half the value of the width of the said beam. The shape of the protrusion is to be defined as a section of a circular plate ( or a section of a pie-chart ) that can be employed in a plurality in terms of the angle subtended by the flat protrusion whereby the said protrusion's extreme edges determine the angle subtended at their relevant axis and the said axis can refer to a connector eye or a concave edge defined by the 'base' radius of 8mm. When such an element is employed it would be possible for a surface to be created in such fashions that accommodate and follow the random disposition of a given wall's curvature, be it of irregular curvature or of a linear character. This system of creating a surface has a drawback in that the said surface created will be delivered in a 2 step as opposed to a single flat plane. The said 2 steps being a result brought about by the overlapping method of positioning pie-sections that form the second portions of corner surface components.

The second portion of corner surface components, shaped like pie-sections can be presented in ( for example ) 45, 90, or 135 degrees as some of the variations among the plurality of angles subtended by the element as depicted by the Figs 21 A to 27D.

The purpose of employing corner surface components is to be understood as suggesting a means of blending with wall structures to progress forward by providing a suitable roof structure that also eliminates the gaps that can arise in comparison to other well known build and play toys. It is not the objective of this application to describe a complete roof building system that eliminates all gaps. The said method delivers the important first step to do the crucial turn for a surface functioning as a wall to progress forward and build on while maintaining a smooth transfer to dispose an adjoining surface to function as a roof with the use of the corner surface components.

The aspects to be the subject of corner surface components are the method of blending with randomly disposed wall structures and the use of sections of circles to overlap in ways to close gaps which is useful in a construction system that is based on primary elements that employ curvatures ( non-linear ) as opposed to straight / linear edged bricks.

In the following figures, the depicted corner surface components are to be taken as of having a first portion of a 40mm length corner beam and the pie-sections are similarly defined by an arc of 40mm radius, but they should be understood to function in the same way even if a plurality of lengths are employed by the said length of the first portion. Connector eyes will exhibit an absence of rotation arresting grooves, and the said absence is deliberate, as the subject of this section does not depend on those details. As in Figures 24A, 24B and 24C, a 24mm length corner beam based components will be depicted for purposes of understanding an aspect of plurality. Corner surface components will be referred to by the subtended angle of their second portions as a first level of sub-division.

The construction system described can be an ideal build and play toy for kids above 6 years old. Even more so true for adults who enjoy modeling structures like popular landmarks around the world. As for kids it provides educational value, without doubt. By attempting features of a new modeling toy it brings out creative thinking and the toy becomes the avenue by which their thoughts are expressed. Furthermore, elements of a universal nature would be incorporated in future to work in conjunction with this construction system.

Methods of incorporating structures to permit mating possibilities with existing well known brands are also being explored. The resulting modeling system would be one that can only be only matched with ERECTOR TM sets. The said popular brand is versatile in the sense that it has an extensive array of elements, but the very number of primary elements brings a natural problem with it. Construction systems of build and nlav cateaorv should stay ideally at a couple of handful of primary elements. Each piece when picked up by the user should immediately be recognized in terms of its character and the manner that it should be deployed. Such ease in recognition and deployment are the elements of this construction system as disclosed earlier as well as by this application.

INDUSTRIAL APPLICABILITY

The components of this construction system as shown in the drawings are all designed with the condition that they are to be manufactured in a single step plastic injection molding process. A lot of revisions have been made to refrain from having any recess areas in individual components that can drive up per unit costs. Straight pull injection molding process is sufficient to complete the elements of this construction system.

ADDENDUM WITH REGARDS TO PRIORITY DOCUMENTS

Note 1 : Fig 3B of this application is based on Fig 3C of Singapore Patent Application 201006489-7. The said document has erroneously ( not intended ) stated in Page 3 Line 33 to Page 4 Line 2, that 48 to 49 is the 'diameter' and 46 to 47 is the 'thickness' but, WHAT IT SHOULD HAVE BEEN is stated correctly ( as intended by applicant ) under the section 'DETAILED DESCRIPTION OF THE DRAWINGS' of the said priority document with regard to the said Figure as Outer diameter of connector eye is 16mm and denoted by distance 46 to 47. Thickness of beam is the distance 48 to 49 and is 0.5 of distance 46 to 47'.

Note 2: Refer to Page 17 Line 29 to Page 18 Line 3 of present application.

Note 3: It has been erroneously stated ( not intended ) in Singapore Patent Applications 201 101057-6 in Page 8 Line 16 that ( Ίη the case of an outermost convex curve, the radii will take a step down as depicted by Fig 5B.' ). The correct statement ( as intended by the applicant ) should mean that the convex second portion would employ a radius that will take a step down from the 'base' of 8mm Figs. 12B1 and 12B2 of this application are based on Fig 5B of the priority document 201 101057-6. The outermost radius is already described to be of 8.00mm by the said priority document in Page 8 Line 8 - 10 and utilized as such by Fig 5B of the said document and further described as such in Page 8 Line 24 - 26 in relation to the said Figure from the said priority document. Note 4: Fig 14A is based on Singapore Patent Applications 201 103326-3 which has erroneously stated that the circle that employs the radial center marked as 21 to be of radius 16mm ( R16.0mm ), the correct marking should be RS.Omm instead of R16.0mm. This is a typo error made in the said priority document. The circumference of the said circle coincides with the distance marker M3 that is the second multiple of 4mm, which should be none other than 8mm. The said circle and the radius reference can also be disregarded in total with no effect to said application's matter.

Note 5: It has been erroneously stated in Singapore Patent Application 201 103326-3 in Paae 3 Line 18 to 21 as, 'is used to derive the second element ( denoted by the suffix B in the Figs ) of the said corner slab coupling by using the said splitting line to create a mirrored ( laterally inverted ) derivative'. The excerpt from the said priority document is not as intended by the applicant. Whereas the correction should be ( as intended by the applicant ), the elements marked with the suffix (B) is the resultant second segment of the 'origin' slab after a split is effected and a selected first segment is allocated and marked with the suffix (A) thus, elements marked with the suffix 'B' are not the laterally inverted derivatives of elements marked with the suffix Ά'. Laterally inverted derivatives would be marked with a prefix 'L', for example slab 20A's mirrored derivative would be marked as L20A and the Figures of the said priority document and the section 'DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS AND DRAWINGS' of the said document relate likewise.

Note 7: It has been erroneously stated in Singapore Patent Applications: 201 103326-3 in Fig 2B that the angle corresponding to M9 as 36.67 degrees. The correct number should be 36.87, which is a mathematical derivative. The incorrect number stated by the priority document is a typo error.

Note 8: Section One of Singapore Patent Applications: 201 103326-3 pertains to construction of corner slab couplings whereby 'corner' should be taken as referring to 90 degrees or in other words right angled.

Note 9: Part 2 of the third section of this application is based on Section Two of Singapore Patent Applications: 201 103326-3. The term 'sub-system' used to refer to the mechanism employing comer surface components by the said priority document is to be discarded (dropped).

Note 10: It as been erroneously described in Page 5 Line 14 to 16 in Singapore Patent Applications: 201 103326-3 as, 'The connector eye or the first portion will resemble a corner beam, being utilised by the rest of the construction system, as such of 8mm width.' Whereas all relevant figures of the said priority document support that the intention of the applicant to be that, the length determining section of the beam portion to be equivalent in width to the connector eye's width in regards to the first portion of a corner slab coupling.
