DETAILED DESCRIPTION OF THE INVENTION

Referring firstly to FIG. 1, a hinge 1 is shown as including a first component 2 and an aligned second component 3 and third component 3′, arranged to rotate about a common pivot axis 4 defined by a hinge pins 5, 5′.

The hinge pins 5, 5′ are fixed to and formed integrally with the first component 2, so as to project from respective first and second ends 27, 27′. The hinge pins 5, 5′ extend co-axially though the second and third components 3, 3′ and thereby provide pivot connections between the first, second and third components 2, 3, 3′.

The hinge 1 also includes first, second and third connecting parts 8, 9, 9′ forming hinge leaves 10, 11, 11′. The second and third connecting parts 9, 9′ are integrally formed with the second and third component 3, 3′. The first part 8 is integrally formed with an angled extension arm 12 that is received in a elongate opening 13 of the first component 2.

The first component 2 includes a housing 14 formed of a cover 15 fixed to a side wall 16 by fasteners 17. When the cover is secured in place, the opening 13 is restricted to an elongate slot 6 to receive the arm 12.

The housing 14 accommodates an adjustment mechanism 18 in an internal recess 40. It should be noted the pivot pins 5, 5′ do not pass through the recess 40 so there is no direct, connection between the mechanism 18 and the pivot pins 5, 5′ and the mechanism operates independently of the pivot pins 5, 5′ as a result.

The mechanism 40 is formed of a device 19 for transmitting rotary adjustment input into linear motion. For that purpose, the device 19 includes a threaded shaft 20 and an internally threaded slide block 21 designed to move lengthwise along the shaft 20 when the shaft 20 is rotated. The housing 14 includes an aperture 28 in a side wall 7 to provide access to the shaft 20.

The slide block 21 includes a tongue 22 that is received in a slot 23 of the arm 12 so that linear movement of the slide block 21 results in corresponding linear movement of the arm 12. The slot 23 has a lateral dimension to accommodate lateral/vertical play between the arm 12 and the slide block 21. As such, the adjustment mechanism 18 can move the arm 12 in and out of the opening 13 so that the first part 2 is displaced relative to the housing 14. This has the effect of laterally moving the first part 8 relative to the second and third parts 9, 9′, providing relative horizontal adjustment between the parts 8 and 9, 9′ whilst allowing for limited free or floating movement between the parts 8 and 9, 9′ in a vertical direction.

The hinge 1 also includes washers 24 and a hinge cap o-ring 24 and a hinge cap 25 to close off the remote ends 26 of the second and third components. A cover may be provided as decorative trim that clips over the housing 14, so that the exterior of the component 2 has the same visual aesthetic as the conventional hinge and provides substantially the same finish as the second and third components 3, 3′.

Referring now to FIG. 2, the hinge 1 is shown in an assembled condition. As may be appreciated, the hinge 1 has a conventional appearance although the front and perspective views of FIGS. 2b and 2d show the elongate slot 6 through which the arm 12 moves in and out, for horizontal adjustment, and up and down to allow the first part 8 to float and establish a rest position relative to the second and third parts 9, 9′.

Referring to FIG. 3a, the aperture 28 can be clearly seen in the first component 2. The aperture 28 provides access for a tool 29 to engage the device 19 of the adjustment mechanism 18 and provide a rotational input to the shaft 20.

In FIG. 3b, the first component 8, in the form of hinge leaf 10, is face mounted to a jamb 30. The second and third components 9, 9′, in the form of hinge leaves 11, 11′, are edge mounted to a panel 31. The hinge leaves 10 and 11, 11′ are shown in an offset condition, where the panel 31 is positioned close to the jamb, such as by a distance of 9 mm. The tool 29 can then be rotated so that the adjustment mechanism 18 drives the arm laterally to displace the hinge leaf 10 horizontally relative to the hinge leaves 11, 11′, to the condition shown in FIG. 3c, where the hinge leaves 10 and 11, 11′ are aligned and the panel 31 is located much closer to the jamb 30, such as in the order of 3 mm.

FIG. 3 b also shows the leaf 10 in a slightly elevated position relative to that shown in FIG. 3a, such that a distance “D” between the two hinge leaves 10, 11 is reduced, as a result of the panel 31 and jamb 30 being slightly offset from an ideal position, that requires the first part to float higher in order to self-adjust in the vertical direction and maintain proper functioning of the hinge 1.

Referring now to FIG. 4, a second hinge 32 is shown, to allow for vertical adjustment and horizontal floating. The hinge 32 is generally similar to the hinge 1 and like parts are denoted with like reference numerals.

The difference between the hinges 1 and 32 is the adjustment mechanism operates in a vertical direction. In particular, the shaft 20 is arranged vertically and the aperture 28 for accessing the shaft 20 is provided in a second end 26 of the first component 2. The shaft 20 is mounted in an axially extending passage 38 formed in the pivot pin 5′ and is operable through a remote end 41 of the pivot pin 5′.

The arm 12 has a horizontally extending slot 33 to receive the tongue 22 of the slide block 21 so that linear movement of slide block 21 drives the arm in a vertical direction. The horizontal configuration of the slot 34 accommodates free lateral movement between the arm 12 and the adjustment mechanism 18, to allow the first connecting part 8 to “float” in a horizontal direction relative to the first component 2.

Referring to FIG. 5, the hinge 32 has an identical appearance to the hinge 1, even though the hinge allows for adjustment in the vertical direction, as opposed to horizontal adjustment. As with the hinge 1, a cover 42 provides an aesthetic similar to a conventional hinge.

Referring now to FIG. 6a, the tool 29 is shown inserted in an opening 43 in the end 26 of the third component 3′, in order to access the adjustment mechanism, to rotate the shaft 20.

In FIG. 6b, the hinge leaf 10 is mounted to the jamb 30 and the hinge leaves 11, 11′ is edge mounted to the panel 31. The distance “D” between the hinge leaves 10 and 11 is in the order of 2 mm. In order to adjust the distance between the hinge leaves 10 and 11, the tool 29 is rotated to drive the leaf 10 downwardly, which serves to increase the distance D by up to, for example, 12 mm, as shown in FIG. 6c. The hinge 32 also allows for the hinge leaf 10 float relative to the hinge leaves 11, 11′, in order to accommodate any horizontal offset between the panel 31 and jamb 30.

Referring now to FIG. 7, a folding panel assembly 34 is shown with the panel 31 mounted to the jamb 30 with an adjustable hinge set 35. The panel assembly may include one or more panels (not shown), as required. More particularly, the panel 31 may be any one of a hinged door, single, bi-parting (French) or part of a multi panel folding door system.

The adjustable hinge set includes two hinges 1 positioned about 100 mm from a top 36 and a bottom 37 of the panel 31. The hinges 1 allow for horizontal adjustment and vertical floating between the panel 31 and jamb 30. A hinge 32 forms an intermediate hinge 38, positioned between the hinges 1, to provide vertical adjustment and horizontal floating.

To mount the panel 31 to the jamb 30 using conventional adjustment techniques would be extremely difficult for a single person to easily achieve. However, the adjustable hinge set 35 enables one person to readily adjust all of the hinges independently, with the hinges 1 providing horizontal adjustment, with vertical floating, while the hinge 32 provides horizontal adjustment and vertical floating. This configuration allows for the panel 31 to be hinged to the jamb 30 without any adverse forces between the panel 31 and jamb 30.

The height adjustment provided by the hinge 32 is preferably in the range of 10 mm and the horizontal adjustment is preferably in the order of 6 mm. However, these ranges may be less or more, as required. Many other modifications and variations can be made without departing from the spirit and scope of the invention described.

As may be appreciated, the invention provides a convenient mechanism for fine thread type adjustment of a panel and there is no need for the conventional morticing of the adjustment mechanism in the panel since the mechanism itself is carried within the hinge component 2. As such, the adjustable hinge of the invention can be face or edge mounted and used on a metallic jamb and door panel, such as made of aluminium, without the need for morticing, which would otherwise be difficult with an aluminium door.

It should also be appreciated the hinges 1, 32 may be provided with only first and second components 2, 3 and the third component 3′ may be omitted, if required.

Lastly, the component 2 is preferably formed with apertures 28 in both the side wall 7 and second end wall 27′ so that the housing 14 is universal and can be used for either vertical or horizontal adjustment, dependent only in the configuration of the adjustment mechanism 18 and shaft 20 inside the housing 14.
