DETAILED DESCRIPTION OF THE EMBODIMENTS

[0010] Referring to the figures, there is shown a hinge 1 for allowing a relative motion between two solid articles. In the embodiment shown in the figures the solid articles are in the form of two chess board halves 30.

[0011] The hinge 1 comprises two pivoting elements 3. Each of the two independent pivoting elements 3 is attached to a hinge pin 4 such that at least one of the two independent pivoting elements is rotatable about the hinge pin 4. The two independent pivoting elements 3 are therefore rotatable in respect of one another.

[0012] Each of the two pivoting elements 3 further comprise a rotatable attachment means including connector 5, shaft 6 and collar 11.

[0013] The two pivoting elements 3 are moveable with respect to one another. As a result articles 30 attached with the pivoting elements 3 are moveable with respect to one another.

[0014] The connectors 5 are adapted to be fitted into the two solid articles 30, such that the two solid articles 30 extend outwardly from the connectors 5. As seen in Figures 22 through 25, in this form movement of the pivoting elements 3 brings the two solid articles 30 from a parallel and adjacent position as shown in Figure 22 to a colinear position as shown in Figure 25.

[0015] The shaft 6 adds strength and length to the hinge 1 to bear the load of the solid articles 30 beyond the pivoting elements 3.

[0016] Each hinge collar 11 is adapted to be rotatably attached with connector 5. Shaft 6 is provided with a screw thread or other means to engage with connector 5. Hinge collar 11 is positioned about shaft 6 or connector 5. The hinge 1 and connectors 5 can thus rotate with respect to the collars 11. The collars 11 are shaped to curve over the hinge element but can be any shape.

[0017] As shown in figures 26 and 27, the hinge collar 11 is attached to the solid articles 30 by way of set screws or other attachment means 26 and 27. Each shaft 6 sits in a bearing tube 7 inset into each solid article 30. Shaft 6 is able to rotate in bearing tube 7. The hinge 1 and the connectors 5 are thus rotatable with respect to the solid articles 30 about the axis of the shafts 6.

[0018] The hinge 1 is rotatable such that the direction of freedom of movement of the pivoting elements 3 with respect to the solid articles 30 is changed. This change in the direction of freedom of movement of the pivoting elements 3 with respect to the solid articles 30 allows the solid articles 30 to move in varying planes with respect to one another.

[0019] In effect, the pivoting elements 3 move such that the hinge pin 4 acts as an axis of rotation. When the hinge 1 is rotated through 90 degrees, the hinge pin 4 and the pivoting elements' 3 axis of rotation is rotated through 90 degrees. As a result the freedom of movement of the hinge is shifted through 90 degrees. Depending upon the size and shape of the solid articles 30 this results in the solid articles being moveable with respect to one another in a different plane or, in certain circumstances means the hinge 1 and pivoting elements 3 are locked so that the solid articles 30 cannot move with respect to one another. That is the hinge 1 is in a locked position.

[0020] The locked and unlocked hinge positions are best shown in use in a flat solid article such as two chess board halves. This is best shown in figures 22 through 25.

[0021] In the locked position shown in Figure 25, the orientation of the hinge 1 with respect to the solid articles 30 restricts the movement of the pivoting elements 3 with respect to one another. In the locked position the axis of rotation of the pivoting elements 3 is perpendicular to the only available axis of rotation of the solid articles 30. As a result the solid articles 30 are fixed in position in relation to one another.

[0022] The collar 10 is attached to or set into the articles 30 being hinged. Each collar piece 11 is inset on one side of the hinge joint 15 extending between the articles 30. Because the collar 10 is set into the two articles 30 the hinge 1 can be flush with the articles 30.

[0023] In use, in order to unlock the hinge 1, a user rotates the hinge 1 with respect to the articles 30. This rotates the connectors 5 and connecting shafts 6 in relation to the articles 30. The collar 11, on the other hand, is fixed with respect to the articles 30. The hinge element 2 can be rotated with respect to the articles 30.

[0024] The hinge can be rotated 90 degrees. A ridge 15 associated with the connectors 5 and an inset portion 16 associated with the collar interact to stop the hinge 1 from rotating an angle greater than 90 degrees.

[0025] In other forms the hinge can be rotated through up to 360 degrees by incorporating a ridge which interacts to stop the hinge from rotating more than 180 degrees, 270 degrees or any angle. When no ridge is incorporated the hinge can be rotated 360 degrees. When the hinge can be rotated through 360 degrees the direction of freedom of movement can be rotated through 360 degrees, allowing the solid articles 30 to move in varying planes with respect to one another.

[0026] In use, the position of the hinge 1 in the hinged article and the opening movement of the hinge 1 prevents the meeting of the articles 30 joined by the hinge 1 along the hinge joint 15. There is therefore no crunching or grinding or opportunity of wear between chess board halves along the hinge joint 15.

[0027] Further, the hinge 1 allows for no hyperextension beyond the position determined as the home position. When the connectors 5 are collinear to one another the pivoting elements 3 meet to prevent hyperextension of the hinge 1.

[0028] The collar 11 and hinge element 2 allows for staged fitting, whereby the collar 11 is attached to the hinged article. Subsequently the hinge element is attached.

[0029] The hinge element 2 is composed of metal, plastic or any other rigid durable substance.

[0030] In another embodiment, the centre of gravity of the hinge element is positioned such that gravity is utilised to automate the rotation of the hinge element 2 within the collar. In another form the rotation of the hinge is actuated automatically by a motor, spring, magnet or other external means.

[0031] In the embodiment described above, the two solid articles 30 comprise chess board halves. In other embodiments the two solid articles 30 may comprise any two solid articles requiring movement in respect to one another, for example scaffolding, flooring, two panels of an articulated dividing screen, a board game board, cupboard doors, and advertising panels.

[0032] Referring to Figures 28 - 33, disclosed is a further embodiment of a hinge 100 of the present disclosure. In this illustrated form the hinge 100 comprises two pivoting elements 103. Each of the two independent pivoting elements 103 is engaged with a hinge pin 104 such that at least one of the two independent pivoting elements is rotatable about the hinge pin 104. The two independent pivoting elements 103 are therefore hingedly rotatable in respect of one another.

[0033] In the illustrated form, each of the two pivoting elements 103 further comprise a shaft 106 extending therefrom. The shaft 106 is fixed with respect to the pivoting element 103. In alternative forms the shaft may take another shape. A rotatable attachment element 105 is engaged with the shaft 106. In the illustrated form the attachment element is in the form of a cylindrical tube 107 shaped to engage the shaft by being positioned about the shaft 106.

[0034] The attachment means 105 are, in some forms, adapted to be fitted to two sections of an article such that the two sections are hinged with respect to one another. The shaft 106 adds strength and length to the hinge 100 to bear the load of the sections of the article. However, in alternative forms the shafts are shaped differently but allow for an attachment element to be rotatably or slideably attached thereto.

[0035] The pivoting elements 103 are therefore rotatable with respect to articles which are engaged with the attachment elements.

[0036] Rotation of pivoting elements 103 with respect to the articles changes the hinge moment or the direction of hinge movement with respect to the article. This change in the direction of freedom of movement of the pivoting elements 103 allows the articles to move in varying planes with respect to one another or alternatively allows for locking of the hing when the hinge moment is aligned with an axis extending perpendicular or at an angle to the articles rather than aligning with the articles.

[0037] In effect, the pivoting elements 103 move such that the hinge pin 104 acts as an axis of rotation. When the pivoting elements 103 are rotated through 90 degrees, the hinge pin 104 and the pivoting elements' 3 axis of rotation is rotated through 90 degrees. As a result the freedom of movement of the hinge is shifted through 90 degrees. Depending upon the size and shape of the articles this results in the articles being moveable with respect to one another in a different plane or, in certain circumstances means pivoting elements 103 are locked into position with respect to one another so that the solid articles cannot move with respect to one another. That is the hinge 1 is in a locked position.

[0038] In use, in order to unlock the hinge 1, a user rotates the pivoting elements 103 and hinge pin 104 1 with respect to the articles. This rotates the shafts 106 with respect to the articles while the attachments elements 105 remain fixed with respect to the articles.

[0039] In this and other forms the pivoting elements can be rotated through up to 360 degrees When the hinge can be rotated through 360 degrees the direction of freedom of movement can be rotated through 360 degrees, allowing the solid articles 30 to move in varying planes with respect to one another.

[0040] The hinge 100 is composed of metal, plastic or any other rigid durable substance.

[0041] The hinge 100 in the illustrated form allows for the hinge to be opened automatically without direct rotational contact with the pivoting elements. Pressure by a user against the hinge allows rotation of the hinge moment with respect to the articles and the attachment elements allowing for a shift in hinge moment without a user manually contacting the pivoting elements 103. This configuration can in turn allow for automatic unlocking of the hinge in, for example, a door.
