Definitions

  • This invention relates generally to joining sheet forms, but can be applied to other forms.
  • this invention describes a flex mechanism for connecting parts to attach a sheet form permanently or temporarily to at least another sheet form or another part.
  • the present invention is used to attach sheets with respect to each other in variable positions. 0 BACKGROUND ART
  • Sheet forms are widely used, in plain sheet form and corrugated or other modified forms.
  • These sheets may be made of many materials, but most commonly wood, metals, composites,5 and plastics.
  • a big advantage of sheet forms is that they are modular in character, which can lower the cost of manufacture, transport, assembly and maintenance. Modular construction can also be quick to assemble, and by relatively unskilled persons.
  • modular elements need to0 be attached to other parts, or connected to, or overlapped over adjacent modular parts.
  • multiple sheets are overlaid to adjacent sheets or flashing details, and the parts attached commonly to underlying wooden or metal rafters or roof trusses using many spaced fasteners,
  • Ways of currently attaching modular sheet parts include fasteners, adhesives, crimping, folding, ⁇ welding, and soldering.
  • connection of parts is the mechanically weaker area of the assembly, so that for example when a cyclone strikes the edges of corrugated sheets can lift. The sheets themselves do not tear, but the modular connection system fails.
  • Laminated forms are commonly used for example in laminated wooden beams, plywood, and cardboard packaging. In these cases adhesives are used but adhesives are relatively expensive and messy to use and there can be problems with implementation except in highly organised factory production, such as in the production of plywood.
  • laminated or adjacent sheet form could be used where mechanical forces, as opposed to adhesives or fasteners, arrange and connect adjacent or overlying sheets securely. At the moment the only way this can be achieved is via crimping, folding, or pressing parts together. This is effective for some situations, eg factory production, but does not allow for subsequent disassembly, adjustment, and most importantly is not suitable for onslte assembly of modular sheet parts to a secure and final waterproof assembly.
  • connection between adjacent parts were easy to create, cheaper and stronger, then the application of sheet materials would be improved for many applications, Including clading, construction, tanks, roofs, siding, concreting form-work, reusable assemblies, emergence shelter, barriers, guard rails, fencing, art form, ducting, piping, floor and bridge conduction.
  • the key principle of this mechanism invention is that there Is a space or void created in at least one area of at least a first part, and a second part Is at least partially inserted into the first part. Then via the application or re-application of a temporary or permanent force the first and second parts are changed in flex or curvature and are brought into surface contact, and/or the contact force is increase/decreased.
  • a mechanism for joining parts where said parts may (but not necessarily) be sheet In form.
  • a mechanism is defined as one where a change in the curvature of adjacent surfaces causes the surfaces to be locked together permanently or temporarily.
  • An alternative definition of a mechanism is defined as one where a change in the curvature of adjacent surfaces causes the surfaces to be unlocked relatively, or adjustable in position relatively.
  • test part A B C in Fig 1 , from a rectangular sheet form folded in half, by 180 degrees along a longitudinal axis 11, to create a U shaped form, with a space 12 created between the sides of the U so that the space between the leaves 13 of the resultant sheet Is generally a regular rectangular void with parallel sides.
  • the space 12 can be defined by the use of a removable and reusable spacer part (not shown) so the folded part has a defined and reliable space 12.
  • the test part has several regions Including leaves 13 with free edges 14 where the leaves 13 are connected by a longitudinal bend 15.
  • a key inventive concept is that this change in an internal void dimension, arising from deformation, (elastic or plastic), can be used to either: 1. Lock one or more parts located relatively loosely/lightly therein the void. This can be further enhanced by utilizing non-planar form sheet material, for example, but not limited to corrugated form sheet.
  • the void will resume its original arrangement, unless the forces applied have been extreme and have plastically deformed the part to a new shape.
  • a flex mechanism for connecting parts as in Fig 2 is one where the part is pre-curved plastically to a form B, before a flex force (usually elastic) is applied, leading to new forms A C.
  • a further alternative form of a flex mechanism for connecting parts is one where the parts are deformed or curved multiple times in the leaf form in one or more axes generally perpendicular to the longitudinal axis.
  • An example of this is when the parts are corrugated in form. This further resists subsequent forces attempting to pull the parts apart in the direction of the second axis.
  • This invention may use parts that are curved or not curved before assembly, but a key character5 is that subsequent forces may change (create, decrease, or increase) the frictional force between at least a first part and at least a second part, which is at least partially-Inserted/ partially-adjacent,
  • This subsequent force may be for example: gravity, an applied force, or a reactive force due to the elasticity of the parts.
  • Assembly sequences may include;
  • Parts are generally formed curved prior to assembly, assembled together, and then further curved to lock the parts together.
  • Parts are generally formed curved prior to assembly, then at least one part is flexed by a temporary force so its curve reduce temporarily to facilitate assembly, and the parts are assembled together, and then the temporary force removed so the parts may be allowed to elastically curve to lock the parts together, (e.g. Fig 11)
  • Parts are generally not curved prior to assembly, assembled together, and then curved to lock the parts together, (e.g. Fig 10)
  • adhesive including contact adhesive or pressure sensitive adhesive may be applied to any surface.
  • an intermediary sheet, mastic, buffer, or film may be included between adjacent part surfaces.
  • connection system such as rivets, pop rivets, clenching, welding, pressing, and fasteners of any kind.
  • the sheet material is folded Into a form that is capable of being pressed to closure, but the actual locking or closure is, at least partially, created by elastic deformation or curving.
  • curving means flexing or twisting, regularly or irregularly, as opposed to a simple curve with one simple radius.
  • the curving force may be generally in one plane, but may be more complex than this, and even be helical in form.
  • This invention describes a connection system between adjacent parts which is easy to create, cheaper and stronger, and therefore the application of sheet materials can be improved for many applications, including clading, construction, tanks, roofs, siding, concreting form-work, reusable assemblies, emergence shelter, barriers, guard rails, fencing, art form, ducting, piping, and bridge contruction.
  • a key advantage of this invention is the connection forces are distributed instead of focal, and therefore lower forces can be used over large areas. This means less stress Is on any particular area. Thinner sheets may be used, and therfore both weight and cost saved. Further (partial or fully) overlapping areas of sheet forms can create "laminated" beams (or “laminated” sheets) for strength. For additional strength or to assist assembly the invention can be attached to conventional beams or parts, which may be linear or curved in form,
  • connection With many prior art connection and building systems the weak area of the final assembly is the connection.
  • Fla 1a is a flex test part, with a pair of, initially, Identical leaves, each with a length, and a thickness (and a width, not shown in this view), that are connected at each leaf end, (by any means), where the flex is increasing progressively from A to B to C.
  • Fig 1b Is an alternative flex test part, with a pair of leaves that are NOT connected at each end, where the flex Is increasing progressively from D to E to F. (Note: The leaves are actually continuously touching.)
  • a flex force F is applied at each end, and a resisting force exists RF, the upper leaf 7 would lengthen and/or the lower leaf 8 would shorten in length.
  • Close up views 3 and 4 show that the butt ends 7 8 are no longer parallel as flex force F is applied. Notes:
  • Fig 1a The thinning/thickening effect in Fig 1a, and the lengthening/shortening effect in Fig 1b arise because of simple geometry, where the radius of the upper leaf must be greater than that of the lower leaf when a downward force F is applied to create a flex.
  • Fig 1c is the flex test part previously described, where the flex is increasing progressively from A to B to C, and as the flex force increases and the radii of curve decreases so the void decreases and the parts would bind to an inserted sheet progressively more.
  • Fig 2 is an alternative flex test part, where the as-formed starting part is pre-curved already as depicted by B.
  • a and C are variations from B after a force Is applied.
  • Part C is part B flexed to increase its curve and narrow the void 21, particularly in the central area 22.
  • Part A is part B de-flexed to decrease its curve, flatten it and widen the void 23, particularly in the central area 24.
  • Fig 3 depicts some flat forms of the invention: In A two sheet forms (truncated at 31) each with a U bend at one end are fitted together. In B and C there are end termination folds 32 33 respectively, which will aid resistance to a pull-apart force as indicated by the arrows 34. In D there is an S connector 35 which plain end sheets 36 are fitted Into. For all the assemblies when a force is applied to deform flex or curve the parts they will bind together via interference surface forces. The geometry change will inherently resist pulling the parts apart in most directions.
  • Fig 3b is a view of Fig 3 but some parts are deleted.
  • the S connector 35 can be seen clearly in D.
  • Fig 4 depicts some corrugated forms of the invention:
  • C two sheet forms each with a generally U bend at one end 41 are fitted together.
  • the U bends include a circle end detail 42 to aid assembly. If the diameter of the circle end is big enough, and/or the corrugation shallow enough, and/or the material flexible enough, the parts can be pre-assembled together side-ways as well as length ways.
  • a flare termination 43 is shown in B.
  • B there is a rod 45 inserted to strengthen the final assembly.
  • A can also form a void to act a conduit passage for electrical cable, or plumbing pipe.
  • Fig 4b is a view of Fig 4 but some parts are deleted for clarity.
  • Fig 5 depicts an S connector 51 in A, and in B and C there are modified S connectors 56 57 which respectively connect sheets 52 to 53 and sheets 54 to 55 but also separate and define a void 58 which may be useful as an air gap for insulation (heat or sound), or indeed a place to put insulation product, electrical cable, services etc.
  • the paired S connectors 56 57 can be joined as one as shown but could equally be connected to another element such as a beam, post or other element. It would be
  • Fig 5b is a view of Fig 5 with the sheet form parts deleted for clarity, so that just the S connector 51 and the modified S connectors 56 57 are shown here.
  • FIG 6 shows the flexibility of the invention:
  • A depicts a modified S connector 61 that may act as a joiner, spacer or vibration dampener
  • B shows a hybrid form where the sheet is corrugated but the termination is flat in form.
  • C shows an assembly where stiffening or attachment elements 62 are inserted before or after flexing the assembly and creating the lock forces.
  • Fig 6b/6c are alternate views of Fig 6 with the sheet form parts deleted for clarity.
  • Fig 7 depicts a number of forms for connecting standard corrugated sheets at the end of the sheet. These can be used as flex mechanism for connecting parts If the sheets are flexed in one direction. Alternately they can be merely joiners where the sheets are not under flex and therefore just convenient ways of connecting adjacent or overlying corrugated sheets.
  • A is a U connector capable of accommodating more than one sheet,
  • B and C are S connectors capable of "joining" two or more conventional corrugated sheets end to end.
  • D and E show that the S form of a sheet, or connector, may have the termination U bends in a "contra” arrangement as in D or an "ortho" (same side) arrangement as In E.
  • Fig 8 depicts a flat form S connector in A, a corrugated S connector in B, Corrugated U connectors are shown in C and D, with the U at differing edges in C and D, relative to the wave of the corrugation of each sheet.
  • E represents an S connector with an orientation of the bend suitable for connecting the ends of corrugated sheets currently available.
  • F depicts the ends of two sheets each with a U detail. This detail allows corrugated sheets to be connected together side ways.
  • Any flex mechanism for connecting parts details in this specification could be as part of a connector item (used to connect sheets or parts), or an integral end or edge detail on a sheet or part.
  • U and S are used in this specification to label forms of detail they are not restrictive to those exact shapes. There are many forms that can be used that are not necessarily to be seen as U or S. Generally a U detail may be seen as having one void, where as an S connector as having two or more voids, commonly at 180 degrees to each other In orientation.
  • Fig 9 shows multiple corrugated single sheet parts A B that have end U details that give the capability of being relatively lopsely fitted together alternately as in C and then locked together by flexural deformation of the sheets (not shown here).
  • Fig 9b shows a pair only of the six multiple corrugated single sheet parts in Fig 9.
  • the end U details are upward in A, and downward in B, and when fitted together there may be a gap between the respective end U details as shown in C.
  • Bespoke design can even deliver laminated forms capable of deformation under load to a limit (relatively), or deforming in a particular character.
  • This bespoke design can act to define the maximum flexural deformation as a result of an applied force.
  • This principle and careful selection of laminated details and overlap can be used to create a leaf-spring type arrangement, and could be used for example to create relatively inexpensive beams for bridges.
  • Alternate sheets can be formed curved in opposite directions and then straightened just enough to allow assembly and then allowed to lock by the natural attempt to resume the as formed curved shape.
  • Fig 10 shows the progressively curved formation of a shelter or building from the multiple single sheet parts depicted in A and B in Figs 9 & 9b, and shown preassembled in flat from in C in Figs 9 & 9b, which Is effectively a new building system.
  • the depiction shown here is at its absolute simplest without any other parts or fasteners, and may for example be used to create a stock or emergency shelter, bam, or open carport using just one new form of corrugated sheet as per this invention.
  • Cross braces may be used for example 62 in Fig 6, Such cross braces may be solid, sheet-form, corrugated, box or any form, and may be generally perpendicular or diagonal in arrangement relative to the sheets they brace,
  • End sheets may have integral attached or inserted lugs (not shown) that are able to be bent, or are pre bent, at an angle, often 90 degrees, to allow fixture of end walls,

At either edges of the spiral form are complementary U details 113 119 which are capable of fitting together, (Details other than U details may be used including a spiral ridge fitting into a spiral groove).
  • A shows that the open spiral form of A may be progressively increased 15 16 117 in diameter, and the U details 113 119 fitted together. If the increase In diameter is within the elastic limit of the material then the spiral form will subsequently "try" to reduce in diameter to that originally present in A. The result is that a spiral flex mechanism for connecting parts will be formed, and a mechanically sound spiral rib with the parts in close frictional contact/connection and is capable of sealing, and/or may have a film or sheet inserted in assembly.
