Description

Adjustable hinge

Field of the invention

The present invention relates to a hinge for attaching a door, window or the like to a fixed structure. In particular, the invention relates to an adjustable hinge which 5 allows for selective adjustment of the relative spacing between a door and a fixed structure. While the specification and preferred embodiments may have particular application to doors and windows, the invention is not limited thereto and may be applied to any situation in which a hinge is employed.

Background of the invention

Adjustable hinges are known. In one known type, the adjustment is achieved by loosening the fixing screws attaching the hinge leaf to the door/jamb. This typically means that the weight of the door must be externally supported before adjustment can be made.

The present invention aims to provide adjustment in two substantially 15 perpendicular horizontal directions, independent from the leaf fixing screws, such that in-situ adjustment can be easily achieved without the need to first support the weight of the door.

It is therefore an object of the present invention to provide an adjustable hinge which overcomes the above stated problem. An alternative object is to provide the 20 public with a useful choice over known hinges.

Reference to any prior art in the specification is not an acknowledgment or suggestion that this prior art forms part of the common general knowledge in any jurisdiction or that this prior art could reasonably be expected to be understood, regarded as relevant, and/or combined with other pieces of prior art by a skilled person 25 in the art.

Summary of the invention

In a first aspect, the present invention provides a hinge for attaching a door, window or the like to a fixed structure, the hinge including:

1002356804

2018275010 07 Dec 2018 at least two relatively pivotable hinge parts connected by a hinge pin, a first one of the hinge parts for attachment to one of the door and fixed structure and a second one of the hinge parts for attachment to the other of the door and fixed structure;

the first one of the hinge parts including:

a knuckle portion and a leaf portion which are relatively adjustable to each other along a first direction of adjustment substantially parallel to the door face;

a threaded adjustment member selectively rotatable about an axis 10 aligned with the first direction of adjustment to effect the relative adjustment of the knuckle portion and the leaf portion; and a clamp to hold the knuckle portion relative to the leaf portion, the clamp including at least one threaded engagement member which is selectively rotatable about an axis extending transversely to the direction of adjustment to engage or disengage the clamp.

In a preferred embodiment, the threaded adjustment member is a screw which is externally threaded. The knuckle and the leaf portion are preferably relatively adjustable back and forth along the first direction of adjustment, e.g. depending upon the direction of rotation of the screw.

Part of the threaded adjustment member may be captured by the knuckle portion or the leaf portion, in turn allowing for rotation but constraining against translation along an axis aligned with direction of adjustment. Preferably, the part is formed as a head of the threaded adjustment member and is so captured by the leaf portion, for example, between the leaf portion and the door, window or the like. Opposite the captured part, an engagement end of the threaded adjustment member may be provided.

In an embodiment, the threaded engagement member engages with a complementary threaded portion. For example, where the part of the threaded engagement member is captured by the leaf portion, then the complementary threaded portion may be provided integral with or secured to the knuckle portion. The

1002356804

2018275010 07 Dec 2018 complementary threaded portion may be a nut constrained against rotation about the axis aligned with direction of adjustment. The complementary threaded portion may be constrained in a slot in the knuckle portion.

Preferably, selective rotation of the threaded adjustment member causes the 5 complementary threaded portion to translate along the threaded adjustment member along the axis aligned with the direction of adjustment, effecting the desired adjustment.

The clamp may further include one or more clamp plates. Preferably there is one threaded engagement member per clamp plate. In each case, the knuckle portion and the leaf portion may be clamped between the clamp plate and a head of the threaded 10 engagement member.

The or each clamp plate may be constrained from rotation about the transverse axis. For example, the or each clamp plate may be constrained in a recess in the knuckle portion. The knuckle portion may be provided with slots to permit passage of the threaded engagement member while still permitting adjustment between the knuckle 15 portion and the leaf portion along the direction of adjustment.

Adjustment between the knuckle portion and the leaf portion may also be effected back and forth in a second direction of adjustment transverse to the first direction of adjustment. The clamp may also be employed to permit adjustment along the second direction of adjustment. Any of the features described below in accordance >0 with the second aspect of the invention may have application.

The second direction of adjustment may be in the form of a rotation or a translation. The translation may be perpendicular to the first direction of adjustment.

In a second aspect, the present invention provides a hinge for attaching a door, window or the like to a fixed structure, the hinge including:

at least two relatively pivotable hinge parts connected by a hinge pin, a first one of the hinge parts for attachment to one of the door and the fixed structure and a second one of the hinge parts for attachment to the other of the door and the fixed structure;

the first one of the hinge parts including:

1002356804

2018275010 07 Dec 2018 a knuckle portion and a leaf portion which are relatively adjustable to each other in a manner including a component in a second direction of adjustment substantially perpendicular to the door face;

at least one threaded spacer which is selectively rotatable about an axis aligned with the second direction of adjustment to effect the adjustment of the knuckle portion and the leaf portion; and a clamp to hold the knuckle portion relative to the leaf portion, the clamp including at least one threaded engagement member which is selectively rotatable about an axis extending substantially parallel to the 10 second direction of adjustment to engage or disengage the clamp.

In an embodiment, the at least one threaded spacer is threadably engaged with one of the knuckle portion or the leaf portion and an end of the threaded spacer bears against the other of the knuckle portion and the leaf portion.

In one embodiment, when bearing against the knuckle portion or the leaf portion, 15 the or each threaded spacer may effect pivotal movement between the knuckle portion and the leaf portion. This pivotal movement may be about a virtual pivot point between the knuckle portion and the leaf portion. Preferably, the pivotal movement is effected by having the at least one threaded spacer disposed in a plane which is substantially parallel to a plane in which the at least one threaded engagement member is disposed.

In one embodiment, when bearing against the knuckle or leaf portion, the threaded spacer may effect translational movement between the knuckle portion and the leaf portion. Preferably, this translational movement is effected by having the one or more threaded spacers located in two planes substantially parallel to the plane in which the threaded engagement member lies and to both sides of that plane.

In one embodiment, each threaded engagement member, each threaded adjustment member and each threaded spacer are independent of fastening members that fix the hinges to the frame or door extrusion. This independence allows the user to adjust the door in-situ without the need of further supporting devices or an additional person.

1002356804

2018275010 07 Dec 2018

In one embodiment, each threaded engagement member, each threaded adjustment member and each threaded spacer will not interfere with the door or frame extrusions.

The clamp may have any of the features already described above.

Detailed description of the embodiments

Figure 1 is a perspective view of a conventional door 1 with hinges 10 in accordance with one preferred embodiment of the present invention. The hinge 10 can 20 allow for relative movement between the door 1 and a fixed structure, such as door frame 2, back and forth along a first direction of adjustment. The first direction of adjustment is defined as a direction that is substantially horizontal and parallel to the face of the door 1. This first direction of adjustment can also be defined as being along the x-axis as shown in Figure 1.

Additionally, the hinge 10 allows for relative movement between the door 1 and a fixed structure 2, wherein at least one component of the relative movement is in a second direction of adjustment. The second direction of adjustment is defined as a

1002356804

2018275010 07 Dec 2018 direction that is substantially perpendicular to the face of the door 1. This first direction of adjustment can also be defined as being along the y-axis as shown in Figure 1.

In describing the embodiments illustrated in the figures, references to the x-axis and y-axis are to be understood as being directions relative to the face of the door as 5 shown in Figure 1 and described above. A reference to the first direction of adjustment may be used interchangeably with reference to the x-axis, and a reference to the second direction of adjustment may be used interchangeably with reference to the yaxis.

Reference in the description may also be made to an axis perpendicular to both I0 the x-axis and the y-axis. This axis will be simply referred to as the z-axis. When describing the components of the hinge, the axes as referred to above will be used. In other words, references to the axes are relative to the face of the door 1 and in reference to the components’ orientation in the assembled hinge 10.

Figure 2 depicts a hinge 10 in accordance with one embodiment of the present 15 invention. A first hinge part 20 can be attached to one of a door, window or the like, or to a fixed structure. A second hinge part 40 can be attached to the other of a door or a fixed structure. The fixed structure may be a frame for a door, a frame for a window, a frame or body of a piece of furniture, or any other item that utilises hinged components. The first hinge part 20 and the second hinge part 40 are pivotably connected by a hinge ’0 pin assembly 60.

Referring now to figure 3, the first hinge part 20 includes leaf portion 22, which can be attached to the door or fixed structure. In this embodiment, the leaf portion 22 is of substantially planar shape with an upper attachment portion 24, a lower attachment portion 26, and an intermediate portion 28. The leaf portion 22 need not have both an 25 upper attachment portion 24 and a lower attachment portion 26, and may instead include only one attachment portion. Alternatively, two or more attachment portions may be provided in order to provide sufficient means for attachment of the leaf portion 22 to the door or fixed structure.

The upper attachment portion 24 and the lower attachment portion 26 as 30 depicted in figure 3 are configured in shape to be accommodated by a C-groove of a

1002356804

2018275010 07 Dec 2018 door extrusion or a frame extrusion conventional for European C-Groove aluminium extrusion systems. However, the shape of the upper attachment portion 24 and the lower attachment portion 26 is not limited to the depicted shape, and may be of a different shape suitable for attachment to the intended door or frame.

The upper attachment portion 24 and the lower attachment portion 26 are provided with through-holes 25 that permit the passage of fastening members 27, such as screws, bolts or the like. The fastening members 27 may provide direct attachment of the leaf portion 22 to the door. Preferably, the fastening members 27 extend beyond the through-holes 25 and further through aligned holes in a backing plate 29. There are two 10 backing plates 29, one for each of the upper and lower attachment portions 24, 26.

As shown in Figures 3A-3C, to attach the leaf portion 22 to the door, the leaf portion 22 is attached to the door extrusion 2. The door extrusion 2 has a C-channel 4 defining a gap 3. The backing plates 29 can then be slid into the gap between the leaf portion 22 and the C-channel 4. The fastening members 27 can then be inserted into 15 through-holes 25 in the respective upper and lower attachment portions 24, 26, and through the aligned holes in backing plates 29. When tightened, the fastening members 27 will ensure that backing plate 29 and leaf portion 22 are clamped together and in turn they will be tightly clamped onto the C-channel 4 of the door extrusion as per Figure 3C.

Referring now to figures 4-4B, the intermediate portion 28 includes a first leg ’0 portion 21 and a second leg portion 23. The first and second leg portions 21, 23 are oriented in a substantially L-shape configuration, with the first leg portion 21 extending substantially perpendicularly from second leg portion 23. In reference to the earlier defined axes, the first leg portion 21 can be said to extend along the x-axis and the second leg portion 23 can be said to extend along the y-axis.

The first leg portion 21 is substantially C-shaped when viewed along the x-axis as best shown in figure 4A. The first leg portion 21 is not limited to the shape and configuration shown in the figures, and can be manufactured with any shaped cross section that is suitable for performing the function required by intermediate portion 28.

The first leg portion 21 includes an outer surface 38 oriented parallel with the z30 axis. The first leg portion 21 also includes an inner surface 39 oriented substantially

1002356804

2018275010 07 Dec 2018 parallel with the outer surface 38 and spaced apart. The first leg portion 21 further includes one or more holes 31, extending between the outer surface 38 and the inner surface 39, for accommodating one or more threaded engagement members 32 (Fig 3), which will be discussed in further detail later. Holes 31 are preferably countersunk 5 holes. The major diameter of the countersunk hole is preferably at the outer surface 38 of the first leg portion 21.

The first leg portion 21 further includes one or more spacer holes 33, extending between the outer surface 38 and the inner surface 39, for accommodating one or more threaded spacers 34, which will be discussed in further detail later. Holes 31 and spacer I0 holes 33 include internal threading that is complementary to the threading of the threaded engagement members and threaded spacers respectively.

The inner surface 39 further includes leaf side recess 41, extending from the inner surface 39 towards outer surface 38. Leaf side recess 41 is shaped to hold a complementary threaded portion 42, which is configured to interact with a threaded 15 adjustment member 36. Leaf side recess 41 is preferably also configured to accommodate the passage of threaded adjustment member 36 therethrough.

Referring now to figure 4B, an inner side view of the leaf portion 22 is illustrated, as would be viewed along the y-axis. The second leg portion 23 includes an attachment side surface 43 and a connection side surface 44 as shown. The attachment side >0 surface 43 is oriented parallel the z-axis, and faces the door to which the leaf portion 22 is to be attached. The connection side surface 44 is oriented substantially parallel with the attachment side surface 43 and spaced therefrom.

Adjustment aperture 35 is configured to accommodate the threaded adjustment member 36, which will be discussed in detail below, and extends between the 25 attachment side surface 43 and the connection side surface 44. This is best illustrated in Figure 4.

The attachment side surface 43 includes a circular recess 46 which defines an abutment surface 45 surrounded by a circumferential surface which is concentric with the adjustment aperture 35. The abutment surface 45 defines the base of the recess 46, 30 extending from the attachment side surface 43 towards the connection side surface 44.

1002356804

2018275010 07 Dec 2018

The second leg portion 23 further includes receiver slots 47, configured to accommodate tab portions 48 of a knuckle portion 30, which will be discussed in detail below. In the depicted embodiment, there are two receiver slots 47, however any number of one or more receiver slots may be provided to achieve the function of accommodating a corresponding number of tab portions 48 of knuckle portion 30.

The first hinge part 20 further includes the knuckle portion 30, an embodiment of which is illustrated in figures 5-5B. Knuckle portion 30 includes a pin receiving portion 51, engagement leg 52, and a bridging portion 53. Bridging portion 53 extends between the pin receiving portion 51 and the engagement leg 52.

I0 Pin receiving portion 51 is of substantially tubular shape, with the longitudinal axis of pin receiving portion 51 being parallel with the z-axis in the assembled hinge 10. Pin receiving portion 51 is configured to receive various components of the hinge pin assembly 60 which facilitates hinged connection with the second hinge part 40.

In the depicted embodiment, bridging portion 53 extends substantially 15 tangentially from the tubular shaped pin receiving portion 51, along an axis parallel with the x-axis. Viewed differently, the pin receiving portion 51 can be said to extend substantially perpendicularly from the bridging portion 53, along the y-axis. The engagement leg 52 extends substantially perpendicularly from the bridging portion 53 along the y-axis but in the opposite direction to the pin receiving portion 51. As is best >0 illustrated in figure 5A, the engagement leg 52 resembles an L-shape in cross section, with a first leg 54 and a second leg 55. The first leg 54 extends substantially perpendicularly from the bridging portion 53.

The first leg 54 includes a leaf side surface 56 and a clamp side surface 57. The leaf side surface 56 is the side of the knuckle portion 30 which interfaces with the 25 intermediate portion 28 of leaf portion 22 at the second leg portion 23. The leaf side surface 56 is substantially planar and abuts against the connection side surface 44 of leaf portion 22 when the knuckle portion 30 is assembled to leaf portion 22.

The first leg 54 further includes the one or more tab portions 48, which extend substantially perpendicularly from the leaf side surface 56. The tab portions 48 are sized 30 so as to fit in the corresponding receiver slots 47 of the second leg portion 23.

1002356804

2018275010 07 Dec 2018

The first leg 54 also includes clamp plate slots 49, to accommodate clamp plates 63, which will be described in greater detail below. Clamp plate slots 49, best illustrated in figure 5B, extend between the leaf side surface 56 and the clamp side surface 57, and are preferably elongate in shape. With reference to the clamp side surface 57 of 5 this described embodiment, a transition region 71 is defined between the clamp side surface portions associated with the first leg 54 and second leg 55. This region may be sloped, as depicted, and include a portion ofclamp plate slots 49 therethrough.

The second leg 55 includes intermediate engagement surfaces 58, oriented substantially parallel with the z-axis. Slotted apertures 59 extend through intermediate I0 engagement surfaces 58 and through to clamp plate slots 49. Each slotted aperture 59 is configured to permit the passage of one of the threaded engagement members 32 through the second leg 55 and towards and partially through to a clamp seat 73 in an inner wall surface 61 of clamp plate slots 49 (See Fig 5B). Each slotted aperture 59 is sufficiently aligned with one of the holes 31 of first leg portion 21, to permit passage of 15 the associated threaded engagement member 32 from leaf portion 22 to knuckle portion 30. The slotted aperture 59 is slotted in shape in order to allow for movement of the knuckle portion 30 during adjustment in the first direction of adjustment. This will be described in detail below.

Engagement leg 52 further includes a knuckle side recess 62, which is shaped to >0 hold at least a portion of the complementary threaded portion 42 (nut), which is configured to engage with threaded adjustment member 36. Together, the knuckle side recess 62 and the leaf side recess 41 form adequate retention of the complementary threaded portion 42 (nut), so that the complementary threaded portion 42 is constrained from rotating when threaded adjustment member 36 is rotated. The engagement 25 between the threaded adjustment member 36 and the complementary threaded portion 42 facilitates the relative movement between the knuckle portion 30 and leaf portion 22 in the first direction of adjustment as will be discussed below.

Reference is now made to figure 6, which depicts the clamping mechanism which holds the knuckle portion 30 relative to the leaf portion 22. The clamp includes the 30 threaded engagement member 32. As described earlier, the threaded engagement member 32 is positioned in holes 31 of first leg portion 21. The threaded engagement

1002356804

2018275010 07 Dec 2018 member 32 is selectively rotatable about an axis extending transversely to the first direction of adjustment to engage or disengage the clamp depending upon the direction of rotation. This axis is an axis parallel to the defined y-axis.

The clamp further includes clamp plates 63, which are positioned in clamp plate 5 slots 49. The threaded engagement member 32 can extend through: the hole 31 of first leg portion 21, slotted apertures 59 of the knuckle portion 30, and an aperture in clamp plates 63. The clamp plates 63 are constrained against rotation by abutment with the connection side surface 44. The clamp is engaged/disengaged by rotation of the threaded engagement member 32 in either rotational direction. When the clamp is I0 engaged, the leaf portion 22 and knuckle portion 30 are constrained from moving relative to each other in any direction.

The process of adjusting the hinge 10 in the first direction of adjustment will now be described. The hinge 10 is assumed to start from a state in which adjustment is constrained. In other words, the hinge 10 is assumed to be in a position in which relative 15 movement between leaf portion 22 and knuckle portion 30 is constrained by the clamp.

In order to allow for the adjustment process to begin, the threaded engagement members 32 are selectively rotated about the y axis in a loosening direction. Preferably, the engagement end of threaded engagement member 32 is located at the outer surface 38, and thus preferably the major diameter of the countersunk holes 31 are at ’0 the outer surface end of intermediate portion 28. The loosening of the threaded engagement members 32 will cause translation of the clamp plates 63 along the threaded engagement member 32 extending the distance between the clamp plates 63 and the heads of the threaded engagement members 32 and thereby disengaging the clamp.

Rotation now of the threaded adjustment member 36 will effect translation of the knuckle portion 30 either back or forth along the first direction of adjustment. The head of the threaded adjustment member 36 is captive in circular recess 46 and thus the threaded adjustment member 36 is constrained from translation along the x axis. The complementary threaded portion (nut) 42, which the threaded adjustment member 36 30 rotates within, is constrained from rotating by the combination of the knuckle side recess 62 and the leaf side recess 41. Thus, the selective rotation of the threaded adjustment

1002356804

2018275010 07 Dec 2018 member 36 will cause the translation of the knuckle portion 30 relative to the leaf portion in the first direction of adjustment along the threaded adjustment member 36. The extent of the movement of the knuckle portion 30 is governed at least in part by the length of slotted aperture 59 in which relative translation of the threaded engagement member 32 occurs.

Once the desired adjustment in the first direction of adjustment has been realised, the threaded engagement members 32 are selectively rotated about the axis extending transversely to the first direction of adjustment (about the y-axis) in a tightening direction, opposite that of the loosening direction to fix the clamps.

Reversing the adjustment in the first direction of adjustment simply requires the threaded engagement members 32 to be selectively rotated in the loosening direction, followed by the selective rotation of the threaded adjustment member 36 in the opposite rotational direction, leading to the translation of the knuckle portion 30 along the x axis in the opposite direction.

Figure 7 illustrates the leaf portion 22 and the knuckle portion 30 at the two extremes of adjustment along the first direction of adjustment. The minimum adjustment in the first direction of adjustment is equivalent to no adjustment as shown by the depiction on the left of figure 7. The maximum adjustment in the first direction of adjustment is shown by the depiction on the right of figure 7.

>0 The hinge 10 is adjusted in a manner including a component in the second direction of adjustment substantially perpendicular to the door face (y axis adjustment). The adjustment of the hinge in this embodiment may be substantially in the second direction of adjustment, or may be a composite direction which includes a component in the second direction of adjustment. The composite direction may include both a 25 component in the first and second directions of adjustment. This may be in the form of a rotation about a virtual pivot point between the knuckle portion 30 and the leaf portion 22.

The process of adjusting the hinge 10 in the second direction of adjustment (y axis) will now be described. The hinge 10 is assumed to start from a state in which

1002356804

2018275010 07 Dec 2018 relative movement between leaf portion 22 and knuckle portion 30 is constrained by the clamp.

In order to allow for the adjustment process to begin, similarly to the case in the previous embodiment, the threaded engagement members 32 are selectively rotated in 5 a loosening direction. The loosening of the threaded engagement members 32 will release the clamp.

Selective rotation of the threaded spacers 34 will now cause the threaded spacers 34 to translate in the second direction of adjustment, towards the intermediate engagement surface 58 of the knuckle portion 30. This results in the ends of the 10 threaded spacers 34 urging against the intermediate engagement surface 58, thereby pushing the knuckle portion 30 away from the leaf portion 22 to either a desired extent or the extent of movement allowed by the clamp release.

Figure 8 illustrates the leaf portion 22 and the knuckle portion 30 at the two extremes of adjustment along the second direction of adjustment. The minimum 15 adjustment in the second direction of adjustment is equivalent to no adjustment as shown by the depiction on the left of figure 8. The maximum adjustment in the second direction of adjustment is shown by the depiction on the right of figure 8.

As would be clear to a person skilled in the art, the positioning of the threaded spacers 34 will influence the relative movement between the knuckle portion 30 and the ’0 leaf portion 22. For example, in the embodiment shown in figure 8, the threaded spacers are located to one side of the intermediate portion 28. Therefore, the force applied by the threaded spacers 34 onto the intermediate engagement surface 58 ofthe knuckle portion 30 will cause a rotation about a virtual pivot point P (Fig 8A) between the knuckle portion 30 and the leaf portion 22. In this case, the relative movement ofthe 25 knuckle portion 30 and the leaf portion 22 will include a component in the second direction of adjustment.

In an alternative embodiment shown in figure 9, there is provided threaded spacers 34 in positions either side ofthe threaded engagement member 32. Thus, when the threaded spacers 34 are selectively rotated, the force applied to the intermediate 30 engagement surface 58 of the knuckle portion 30 is more evenly distributed, thereby

1002356804

2018275010 07 Dec 2018 causing the movement of the knuckle portion 30 relative to the leaf portion 22 to be substantially in the second direction of adjustment. This is further illustrated in figure 9A.

Once the desired adjustment in the second direction of adjustment has been realised, the threaded engagement members 32 are selectively rotated in a tightening 5 direction, opposite that of the loosening direction.

To reduce the extent of adjustment in the second direction of adjustment or return the relative spacing between the knuckle portion 30 and the leaf portion 22 back to the pre-adjustment position, the threaded spacers 34 are first selectively rotated in the opposite direction, thereby causing the threaded spacers to retract towards the leaf 10 portion 22 and to a desired location out of contact with the intermediate engagement surface 58 of the knuckle portion 30.

The above adjustment will loosen the effect of the clamp and thus, the clamp is then re-tightened to pull the knuckle portion 30 back towards to the leaf portion 22. The pulling is achieved by a force exerted by the clamp plate 63 on the inner surface of 15 second leg 55.

It will be understood that the invention disclosed and defined in this specification extends to all alternative combinations of two or more of the individual features mentioned or evident from the text or drawings. All of these different combinations constitute various alternative aspects of the invention.
