Definitions

  • the invention relates to a system and method for folding and or joining composite board such as honeycomb board to form stylish consumer objects. More particularly, it relates to a system and method for folding and joining rigid honeycomb cardboard where the fold is curved and comprises a partly or a fully cylindrical shape.
  • the invention teaches a method for creating consumer objects and structures, which comprise fashionable shapes and which may be rendered with images to make them more appealing as well as improving the structural integrity of the said objects.
  • the invention makes possible the creation of a new form of protective packaging material which can be shaped accordingly to protect goods from being damaged in transit.
  • this invention extends the teaching of an earlier patent application made by the same applicants entitled System and Method for Rendering an Image onto an Object and Objects Formed of the Same, filed August 15th 2005 at the UK Patent Office with number GB-A-0516755.6
  • This earlier patent application comprehensively taught an inventive method for creating a range of goods, which were enhanced by a novel image rendering technique.
  • the current invention is particularly addressed towards the creation of enhanced consumer goods such as storage boxes, office dividing systems, cupboards, plant containers, chairs, tables, beds, children's playhouses such as Wendy-houses, dolls houses, bags, pet boxes, pet homes, and caskets.
  • the invention is further directed towards the creation of a new range of protective packaging material for glass bottles and other fragile products.
  • the novel and inventive cardboard folding method makes use of honeycomb board which is cut in a particular way. This cutting method leaves the outer surface intact leaving it suitable for rendering with images as required.
  • the cause of the reduced strength at the fold is due to the removed material, which in itself adds complexity to the manufacturing process of folded shapes such as boxes comprising this fold. If it were possible to create a fold in the material which did not require the removal of any material, this would greatly simplify the manufacturing of shapes and boxes and also there would not be any waste generated.
  • honeycomb-like board comprising a composite of outer sheets and filling material separating the sheets, which may comprise additional inner sheets, is the difficulty of curving this material.
  • rigidity and the resistance to curving are generally considered to be measures of the strength of the said board.
  • honeycomb board In the instance of the honeycomb board, if it were possible to curve the material, while maintaining the strength and rigidity in the vicinity of the joint, many new and exciting products could be formed as well as a range of low cost and highly rigid protective packaging material.
  • This provides alternative rows of rectangular sections wherein one forward edge, which is parallel to the axis of the fold, of each rectangular section of each row is deformed under pressure with row one having its left edge depressed, row two having its right edge depressed, row three having its left edge depressed and so on to create an alternating pattern of depressions.
  • composite board such as honeycomb cardboard which comprises interleaved rectangular sections wherein each section has one depressed forward edge which moves into and under the non-depressed rear edge of an adjacent section wherein the width of each rectangular section normal to the axis of the curved fold determines the rate of curvature of the fold.
  • composite board such as honeycomb cardboard
  • composite board such as honeycomb cardboard comprising two sheets of cardboard separated by a rigid spacing material or the like of the type, for example made by Dufaylite of Cromwell Road, Saint Neots, Cambridgeshire UK, wherein a variety of the objects are formed from folding said material using novel joints according to the current invention.
  • the system and method for folding and or joining composite board making use of a highly effective and efficient technique in the preferred embodiment makes possible the creation of a product range formed of low cost constructional materials comprising diverse curved and angled shapes while maintaining the structural integrity of the said objects in the region of the curves and angled joints.
  • novel joints make possible a whole new range of stylish shapes and forms of consumer products which are not only enhanced in structural integrity and by the imagery which they bear using the method of the invention but are also cheaper.
  • the invention is particularly directed to forming objects made of lightweight but strong materials such as reinforced cardboard or plastic composite boards comprising two outer sheets separated by a rigid spacing material, which is known to be generally difficult to curve or shape in non rectilinear forms.
  • the current invention provides for a system and method to create stylish objects of enhanced appearance and diverse curved and angular forms made possible by combining the rendering technique with a number of novel folding and jointing techniques.
  • the system and method according to the invention has advantageous application to the construction of all manner of containers and consumer structures such as office dividing walls, Wendy-houses, tables and chairs, and packaging materials and insulating materials for pipes and the like.
  • FIG. 1 illustrates a schematic of the two sections of one embodiment of the variable angle dovetail joint which shows the dovetail profile section comprising a rectangular void at the base for forming secure angled joints according to the system and method of the current invention.
  • FIG. 2a illustrates a schematic of a section of composite board comprising an array of perpendicular cuts according to the current invention which makes possible the curving of the composite board while maintaining high torsional and compressional resistance.
  • FIG. 2b illustrates one way of depressing the forward edge of adjacent rectangular sections where alternating adjacent rows are depressed in the counter orientation.
  • FIG. 2c illustrates an alternative way of depressing the board according to an alternating scheme where both the forward and rear edges of every second rectangular section are depressed and also where alternating adjacent rows are depressed according to an alternating scheme.
  • FIG. 3 illustrates the way in which the board can be curved by making use of the alternating depressions according to either FIG. 2b or FIG. 2c or a mixture of the two.
  • FIG. 4a shows a cross sectional view of a single rectangular cut section before and after its leading edge is depressed with a tool to cause the depression.
  • FIG. 4b shows a cross sectional view of a single rectangular cut section before and after both its leading and rear edges are depressed with a tool.
  • FIG. 5 shows how a depressed section can move under the non-depressed section of an adjacent section when the board is curved.
  • FIG. 6 shows how a cutting tool can be used to make opposing compressional joints for folding the material.
  • FIG. 7 shows an example of how a section of board can be curved according to the invention and be integrated with a horizontal surface to form a seat.
  • FIG.l therein illustrated is an example of a dovetail joint according to one embodiment of the current invention.
  • This joint is intended to be used with composite honeycomb board which comprises two outer rigid sheets and an internal filling material.
  • the board comprises two sections (1/ 4) where a first section (1) comprises an uncut section of board adjacent to a second section (4) which has had the inner surface of rigid material and the internal filling material removed to leave an area of rigid card and a dovetail section (2) in the centre of this area.
  • a dovetail section (2) Directly at the base of the dovetail segment (2) is a rectangular void (3) which comprises an area ⁇ a times b). Since the rigidity of the composite board is due to two outer rigid sheets separated by filling material, by removing all but the outer rigid material, the board will fold at that point.
  • the rectangular void (3) provides a cavity for the base of the dovetail joint to fold into, thereby adding strength to the dovetail at that point.
  • the width (a) of the rectangular void and the width of the base of the dovetail joint determine the angle of the fold of the board at that point.
  • FIG.l shows the board folded at ninety degrees and further shows a section of board with a dovetail section removed which matches the protruding dovetail above the shoulder (d). It is intended that this section (6) is an example of the end of another section of board or the other end of the same section of board which is folded back to be joined to the end section (7). The two end sections do not show the full extent of the board which is joined but only the detail of the dovetail joint.
  • dovetail joints may be used to secure the joint between two sections of board.
  • the flat section of rigid card (4) surrounding the dovetail profile (2) may be used to secure the two sections (6,7) together by glue.
  • FIG.2a therein illustrated is a section of composite board (8) which has had a series of vertical cuts (9) and horizontal cuts (10) cut into one surface of the board leaving an area of rectangular sections cut into one surface of the board.
  • the horizontal distance between the vertical cuts (9) and the horizontal cuts (10) determines the rate of curvature of the board. If the cuts (9) are very close together, the curvature of the board is high.
  • the board may comprise different horizontal widths between the vertical cuts 9 to curve the material at different rates in the same section of board.
  • FIG. 2b and FIG. 2c now refer to part of that section identified in FIG. 2a as area 8a.
  • FIG. 2b is shown an example of an area of 12 rectangular sections in separate rows (13,14) wherein each section comprises one depressed edge in an alternating pattern (11,12) such that a first row (13) has the right edge depressed and the adjacent row (14) has the left row depressed.
  • FIG. 2c is shown an alternative embodiment where alternating rectangular sections of board have their forward and rear edges depressed accordingly.
  • FIG. 3 a curved section of board (17) according to the current invention which shows how the rectangular sections move together when end A is curved towards end B and how the vertical cuts are out of alignment with the cuts in adjacent rows and how this thereby provides increased compressional resistance at right angles to the direction of curvature.
  • FIG. 4a is shown a side view of a single cross section of board (18) and the result of depressing one edge (21) by way of a depressing tool (19) which moves downwards in a vertical motion (20).
  • This tool (19) may comprise part of a machining, process or it may form an element of a rotary tool which comprises teeth in the shape of the desired depression profile.
  • FIG. 4b shows a similar cross section of board in which both ends of the material are depressed to provide a depression pattern as shown in FIG. 2c.
  • the tool in this case (23) will form part of a machine process to stamp the material in accordance with the desired depression pattern.
  • FIG. 5 shows how the depressed edge (24) can move into the composite board and under a non-depressed edge (25) when the material is curved.
  • FIG. 6 shows an alternative cutting method to create an opposed compression joint using a single cutting tool comprising a handle (27) and a cutting wheel (28) which produces a cut (29) into one of the rigid sheets of the board.
  • the board when folded creates a very strong joint by making use of the internal resistance of the honeycomb filling without requiring that any material be removed.
  • FIG. 7 shows an example of the way in which a chair (701) may be formed from a sheet of composite board where the two opposing ends are symmetrically cut and curved in opposition and a single sheet of rigid board (703) is slotted through a void in the centre (702) and anchored at either end through a slot (704) and fixed by way of a dovetail joint according to the current invention (705) which in turn may be securely glued and covered.
  • An alternative embodiment of the chair as shown in FIG. 8 may comprise an extension of the lower wall of the chair which wraps around and under the horizontal seat (703) at each end and locks into a slot in the wall to give additional support below the seat.
  • the same method may be used create an extension of an office dividing system where the curved end wraps completely around and can form various table areas in elegant opposition which are fully integrated with dividing walls and which may end with a closed cylindrical end which provides additional stability to the structure.
  • This closed cylindrical end may, in one embodiment also comprise the basic structure to hold a set of drawers, each of which comprise a curved end to match the curvature of the system.
  • the end of the wall divider may terminate in a cylinder to hold a plant pot which also adds some weight and stability to the structure.
  • the same system and method may be used to create a child's Wendy house and all the furniture within it at very low cost.
  • the table and chairs may be made very stylish and attractive using the method of the current invention.
  • the innovative curving method of the current invention makes possible the creation of low cost, high insulating temporary protective shelters to be used in situations of emergency.
  • the outer surface of the composite board can be coated with a waterproof vinyl-like sheet or paint or compound.
  • the curving of the board makes possible the creation of a continuous surface which will provide a much better resistance against damp and cold and against wind than simple tents. Tents in such instances are generally not warm enough while composite board has indeed quite high thermal insulation.
  • the board can be curved and locked into shape using the joints of the current invention and a compound can be injected into the curved structure which will set and lock the structure into a solid shape. This curving and locking of the sheet into a closed structure having high thermal resistance which can be subsequently set into shape using an injection of sealant compound demonstrates the importance of this invention and the diverse range of applications to which it may be applied.
