BRIEF INTRODUCTION TO THE FIGURES

For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings in which:

FIGS. 1-5 show hinge assemblies according to example embodiments of the present invention;

FIGS. 6 and 7 show the hinge assembly of FIG. 5 in more detail;

FIG. 8-10 show an actuation means for use with example embodiments of the present invention; and

FIG. 11 shows sealing elements for use with example embodiments of the present invention.

DESCRIPTION OF EXAMPLE EMBODIMENTS

Referring to FIG. 1 there is shown a hinge assembly comprising first and second hinge plates 10, 12 mounted for relative rotation about a pivot 14. The first hinge plate 10 comprises a mount 11 for coupling to a door component. In the embodiment of FIG. 1 the first hinge plate 10 and the mount 11 thereof are for coupling to a door, and the second hinge plate is for coupling to a door frame. The hinge assembly is arranged to permit a degree of relative linear movement between the second hinge plate 12 and a door coupled to the mount 11, the degree of linear movement being independent of the relative rotational position of the first and second hinge plates 10, 12 within their range of relative rotation about the pivot 14.

Using the hinge assembly in this way a door coupled to the mount 11 can move in a linear translational fashion into and against the door frame when the door is shut in the door frame. Pressing on the door can move the portion of the door nearest to the hinge assembly and the portion of the door furthest across from the hinge assembly in generally parallel directions and by the same amount of linear distance. Normally, with a hinge which is arranged with hinge plates that only pivot relative to one another, pressing the door will not move portions of the door coupled to the first hinge plate any closer to the door frame as the portions of the door further across the door form the hinge bear on the door frame. The standard door arrangement potentially results in a poor fit between the door and the door frame, and can thus prevent adequate sealing against drafts and ingress of water.

In the embodiment of FIG. 1, the mount 11 is arranged such that linear movement is permitted in a direction A parallel to a planar face 15 of the first hinge plate 10. The direction A as indicated corresponds to linear movement in a radial direction, perpendicular to the axis of the pivot 14. The mount 11 is arranged to cooperate with other features of the first hinge plate 10 such that linear movement is restricted to movement backward and forward in a single dimension.

The mount 11 comprises a recessed portion 13 into which the first hinge plate 10 locates in use. Also, the first hinge plate 10 comprises opposed walls 16 extending from the planar surface 15, between which the mount 11 is in use arranged to locate. In the embodiment of FIG. 1, the recessed portion 13 locates between the opposed walls 16. To either side of the recessed portion 13 the mount 11 comprises mounting extensions 18 that extend beyond the planar surface 15 of the first hinge plate to enable the hinge assembly to be coupled to a door component. The recessed portion 13 of the mount 11 is recessed relative to the mounting extensions 18. A typical installation of the hinge assembly of FIG. 1 might comprise fixing through the extensions 18 into the side face of a door, for example using screws.

The mounting extensions 18 are arranged to slidably engage the edges of planar surface 15 of the first hinge plate 10, such that cooperation between the mounting extensions 18 and the edges contribute to defining the permitted movements of the mount 11 of the first hinge plate 10.

Also relevant to the movement of the mount 11 of the first hinge plate 10 is biasing means 20 arranged to bias the mount 11 toward the pivot 14. In the embodiment of FIG. 1 the biasing means 20 comprises a pair of sprung steel blades, of depth comparable to the wall 16 and compressible to move 2 mm between extended and fully elastically compressed configurations. The biasing means 20 is arranged between a wall 16 of the first hinge plate and the mount 11 and is arranged to push the mount 11 in a direction parallel to the planar face 15 of the first hinge plate 10. The biasing means 20 is compressible under force from the mount 11 to move the mount away from the pivot 14. The biasing means 20 is arranged to act parallel to the direction A. In normal operation of the door to which the hinge assembly is fixed, the biasing means 20 holds the mount 11 over in the direction A, close to the pivot 14. Pressing the door away from the pivot 14 against the bias of the biasing means 20 enables the door to move evenly against the door frame, enabling a good seal to be formed between the two. The operation of pressing and holding the door against the door frame will now be described in more detail, with reference to FIGS. 8-11.

FIGS. 8-10 show a door assembly including a door, a hinge assembly as described above and a door frame 40. The door 30 is coupled to the mount 11 using the extensions 18, and the door frame 40 coupled to the second hinge plate 12. FIGS. 8-10 also show an actuation means arranged to move the door 30 against the bias of the biasing means 20 and to lock the door 30 in place in the door frame 40. The actuation means is in part carried on the door 30 and provides multiple points of engagement between the door 30 and the door frame 40, in the form of blades 52 arranged to pivot into and press against recesses 42 in the door frame 40. The blades 52 and coupled by a linkage 54 so as to all operate in response to a users actuation input, for example in response to a user turning a handle about actuation point 56. The recesses 42 comprise tapered sockets, arranged to urge the blades 52, and correspondingly to urge the door 30 away from the pivot 14 as the blades move into place in the frame 40. The actuation means can in further embodiments (not shown) conveniently be coupled to a locking arrangement, to give an integrated security benefit along with the benefit of properly sealing the door 30 against the door frame 40.

FIG. 11 shows a sealing element 60 in both half-round and rectangular section, positioned in the door frame 40 so as to lie between the door frame 40 and the door 30 when the door 30 is closed in the frame. The sealing element 60 comprises a rubber strip, and in alternative embodiments may be carried on the door 30 rather than on the door frame 40.

For a standard doorway in a domestic building the door assembly of FIGS. 8-11 may suitably comprise two, or three hinge assemblies as described above, but it will be appreciated that the size and number of hinge assemblies can be varied according the requirements of the door which is to be carried thereon. The dimensions given on the Figures are examples of those suitable for a standard doorway in a domestic building.

FIGS. 2-7 show further example hinge assemblies that permit a degree of adjustment to be made between the mount and a hinge plate. Although not shown the hinge assemblies of FIGS. 2-7 my further comprise biasing means and permit relative movement between hinge plate and mount, but may conveniently also enable the mount to be positioned relative to the hinge plate and then locked in place then subsequently re-adjusted to allow the mount to move to a different relative position before being again locked in place.

FIG. 2 shows a mount 11 comprising projections 21, some of which extend into openings 22 on the first hinge plate 10. The projections 21 are arranged to slidably engage the edges of the corresponding openings 22 on the first hinge plate 10, and edges of the first hinge plate 10, with cooperation between the projections 21 on the mount 11 and the edges on the first hinge plate 10 defining the permitted movements of the mount 11 relative to the first hinge plate 10. The FIG. 2 embodiment comprises projections 21 and openings 22 which enable movement in direction A, whereas FIG. 3 comprises projections 21 and openings 22 which enable movement in direction A and the perpendicular direction B. FIG. 4 shows and embodiment in which the projections 21 each extend over a generally smaller area than the corresponding openings 22, enabling relative movement to take place in directions A and B.

In each of FIGS. 2-4 some of the projections 21 comprise threaded bores 23 as fastening features for use in securing a locking means 19 to the mount 11, for example by screwing through the locking means 19 and clamping the mount 11 to the first hinge plate 10 to hold them together in the hinge assembly and to resist relative movement by surface friction therebetween. Some example embodiments may further comprise friction enhancing features to reduce the clamping force needed to lock the mount 11 in place.

FIGS. 5-7 show an embodiment of the hinge assembly in which the pivot 14 is arranged to permit a degree of linear movement between the first and second hinge plates 10, 12 in a direction parallel to the pivot axis, and comprises an adjustment means in the form of a screw which is used to set the position of the first hinge plate relative to the second hinge plate on the pivot axis 14 such that the relative position does not change as the first and second hinge plates move about the pivot axis.

The embodiments described herein are of simple construction, but provide a useful modification to traditional hinges by enabling propose positioning of a door in a door frame. The properly positioned door can be highly draft and flood resistant.
