Definitions

  • the invention relates to a hinge and fitted assembly.
  • the device is likely to find particular utility for use with hinged doors which are made from extruded aluminium or plastics, including for example UPVC. Accordingly, much of the following description will relate to such use; however the use of the hinge for other applications is not thereby excluded.
  • Hinged doors are typically located in a fixed frame, and are usually rectangular - comprising a hinge edge and an opposed locking edge joined by two connecting edges.
  • the frame surrounding the door typically comprises three edges (the floor or ground corresponding to the fourth edge); for simplicity the three frame edges will also be referred to herein as the hinge edge, locking edge and connecting edge respectively.
  • a door typically opens about a substantially vertical hinge axis, so that both the hinge and locking edges of the door and frame are substantially vertical in use, with the (single) connecting edge of the frame being above the door in the gravitational direction.
  • hinges are known for pivotably connecting the hinge edge of a door to the hinge edge of its frame, the hinges being located fully or in part between the respective hinge edges of the door and frame.
  • doors of extruded plastics have a peripheral lip overlying a part of the frame, the lip being present also on the hinge edge of the door.
  • the lip is provided to carry a seal, which when the door is closed contacts the frame, the seal helping to ensure adequate weather sealing for this type of door.
  • the presence of the lip on the hinge edge of the door requires the door to be moved away from the frame (i.e. substantially out of the plane of the frame) as the door is opened, which precludes the use of many of the known types of hinge.
  • Plastic windows are also known, which share the feature of the peripheral lip.
  • a certain type of hinging component known as a "stay” or in particular a “four bar linkage stay”.
  • a stay or in particular a “four bar linkage stay”.
  • Such a stay is shown, for example, in US patent 2,784,459.
  • stays there are two such stays fitted to an opening window, the stays being fitted to the connecting edges of the window and frame rather than directly to the hinge edges.
  • Such stays are located in the gap between the connecting edges of the window and frame when the window is closed (i.e. they are not visible to an onlooker), and yet permit the window to be opened out of the plane of the frame.
  • the present invention seeks to reduce or avoid the above-stated disadvantages of the known door hinges.
  • a hinge for a panel mounted in a frame comprising a first arm and a second arm, the first arm being adapted for securement to the hinge edge of one of the panel and frame, the first and second arms being relatively pivotable about a hinge axis, characterised in that the second arm is adapted for indirect connection to the hinge edge of the other of the panel and frame by way of at least one further arm.
  • a hinge assembly comprising a panel mounted to a frame by at least one hinge, the hinge comprising a first arm and a second arm, the first arm being secured to the hinge edge of one of the panel and frame, the first and second arms being relatively pivotable about a hinge axis, characterised in that the second arm is not directly connected to the hinge edge of the other of the panel and frame, so that the hinge axis can move relative to the other of the panel and frame during relative pivoting of the first and second arms.
  • the hinge axis lies between the hinge edges of the panel and frame when the panel is closed, and yet lies outside the plane of one of the panel and frame when the panel is open.
  • the hinge axis lies between the hinge edges of the panel and frame when the panel is closed, and yet lies outside the plane of one of the panel and frame when the panel is open.
  • the further arms pivotably mounted to the second arm so that upon pivoting of the further arms the second member is moved away from the said other of the panel and frame.
  • the further arms provide part of a "parallelogram" arrangement.
  • connecting means to cause pivoting of the further arm or arms upon pivoting of the first arm relative to the second arm. Accordingly, upon pivoting of the panel relative to the frame (e.g. opening of the door) the further arm or arms will also automatically be pivotted, so moving the hinge axis away from the frame.
  • the said connecting means to pivot the further arm or arms comprises at least one connecting member pivoted to the second arm and a rod in sliding engagement with the first arm.
  • the connecting member is additionally pivotably mountable, or is pivoted, to the other of the panel and frame; preferably, the connecting member is an extension of one of the said further arms.
  • the first arm will be adapted to be connected to, or will be secured to, the panel, e.g. the door, whilst the second arm is adapted to be indirectly connected to, or secured to, the frame.
  • the second arm is not directly secured to the frame it can move relative thereto, and in particular the hinge axis can move relative to the frame during relative pivotting of the first and second arms.
  • a hinge for a panel mounted in a frame comprising a first arm and a second arm, the first and second arms being pivotably interconnected, respective mounting means for the first arm and for the second arm, the mounting means for the first arm being carried by the first arm, characterised in that the second arm is movable relative to its mounting means.
  • the mounting means for the first arm comprises at least one aperture for receiving a fixing such as a screw or the like; usefully also, the mounting means for the second arm comprises at least one aperture for receiving a fixing, the aperture being located in a bracket which is pivotably connected to the second arm.
  • the first arm, second arm, and further arms are manufactured as metal pressings; this provides an additional advantage over the butt hinges described above.
  • the known butt hinges are manufactured as metal castings, and it is a recognised feature of a metal pressing that it is stronger than a casting having the same dimensions.
  • the hinge according to the invention will provide greater resistance to an attack on the hinges because when an intending intruder seeks to jemmy the door away from the frame (as is customarily the method of forced entry), the location and arrangement of the hinge components will result in such jemmying action acting to compress or crush one or more of the hinge components.
  • the action is to pull the hinge components apart. Since castings are strong under compression the hinge of the present invention therefore has another advantage over the known butt hinge when under attack.
  • the door panel and frame assembly 1 comprises a door panel 2 and frame 3, both of which are rectangular in front view.
  • the door 2 is formed from four lengths of extruded plastic, mitred and joined at the corners, in known fashion, and the frame 3 is similarly formed of three lengths of extruded plastic.
  • the door 2 comprises a hinge edge 4, a locking edge 5 and two connecting edges 6.
  • the frame comprises a hinge edge 7, locking edge 8 and single connecting edge 9.
  • the door 2 has an infill panel 10, which may for example be glass or other known material.
  • the frame 3 is located adjacent floor 11 and within surrounding brickwork 12.
  • the edges 4 and 5, and at least the upper edge 6 of the door 2 have a lip 14 (Figs.2,3) which in the closed door condition overlies a part of corresponding edges 7,8,9 of the frame 3.
  • the lip 14 of the door hinge edge 4 overlies the wall 15 of the frame hinge edge 7.
  • the lip 14 will typically have a recess to locate a seal which in the closed condition of the door will engage the wall 15, to prevent the ingress of dirt and moisture therebetween.
  • the hinge 20 comprises a first arm 21 which is pivotably mounted to second arm 22 by a pivot pin 23.
  • the pivot pin 23 provides the hinge axis A between the first arm 21 and second arm 22.
  • the first arm 21 is secured to the hinge edge 4 of the door 2, suitably by screws or other known fixing means.
  • the second arm 22 is indirectly connected to the hinge edge 7 of the frame 3.
  • the second arm 22 is connected to the hinge edge 7 by way of two further arms 24,25, the further arms each being pivotably connected both to the hinge edge 7 of the frame and to the second arm 22. Accordingly, and as more clearly shown in Fig 9, the two further arms 24,25, the second arm 22, and a part of the hinge edge of the frame form a parallelogram whereby the second arm can be moved towards and away from the hinge edge 7.
  • the second arm 22 is maintained parallel to the surface of the hinge edge 7 as it moves relative thereto.
  • the maintenance of the second arm parallel to the hinge edge is not critical to the invention, and that some alteration in the positions of the respective pivots and/or spacing between those pivots can be made without affecting the utility of the hinge.
  • each further arm 24 has an extension piece 26 (Fig.3) which permits the arm 24 to engage the first arm 21.
  • the extension pieces 26 of the respective further arms 24 are linked by a rod 27 (Fig.3), part of which rod lies within a pair of elongated tracks 28 in the first arm 21.
  • the extension pieces 26 and rod 27 comprise a connecting means by which pivoting of the first arm 21 relative to the second arm 22 is communicated to the further arm 24 and also to the further arm 25.
  • the tracks 28 do not engage the rod 27 for the first few degrees of pivoting of the door 2, so that the door lock edge 5 clears the frame lock edge 8 before the second arm 22 is moved away from the frame hinge edge 7, i.e. the door lock edge 5 does not foul the frame lock edge 8 as the second arm 22 is moved away from the frame hinge edge 7.
  • the hinge 20 when the door is closed, the hinge 20 lies within the gap between the door hinge edge 4 and the frame hinge edge 7.
  • the gap has a width w of between 13 mm and 17 mm, and a depth d of at least 45 mm.
  • the components of the hinge 20 are chosen to fit within this gap, and not to be visible from outside (or inside) the door when the door is closed. Accordingly, an intending intruder will not be alerted to the number of hinges fitted to the door, or to the positions thereof. In this regard, there will typically be three or four hinges 20 fitted to the door 2, spaced apart along the hinge edges 4,7, though more or fewer hinges can be used depending upon the weight of the door 2.
  • Fig.5 shows the construction of the first arm 21 of the exemplary embodiment.
  • the arm 21 is a metal pressing, having a two side walls 30 interconnected by a plate 31.
  • each side wall 30 has a track 28 formed therein, and an aperture 32 for receiving pivot pin 23.
  • Fig.6 shows the construction of the first further arm 24 with its integral extension piece 26.
  • the arm 24 is also a metal pressing, and has two side walls 33a,b interconnected by a plate 34. In addition, there is a projection 35 standing proud of the side walls 33a.
  • the side wall 33a has two apertures 36,37, the aperture 36 being adapted to receive a pivot pin 38 (Fig.2,3) so that the arm can be pivotably mounted to bracket 53 which is secured to the frame 3, the aperture 37 being adapted to receive a screw or similar fixing for one end of the rod 27.
  • Fig.2 there are two further arms 24, being mirror images of each other, the rod 27 being mounted between the apertures 37 of the respective further arms.
  • the projection 35 has an aperture 39 which carries a pivot pin 40 (Fig.3) which pivotably connects the further arm 24 to the second arm 22.
  • the purpose of the projection 35 is to space the mounting of the pivot pin 40 from the side wall 33a, so that in the closed condition of the hinge one of the side walls 30 of the first arm 21 can lie within the space 41 between the projection 35 and the side wall 33a.
  • Fig.7 shows the construction of the second arm 22.
  • the arm 22 is also a metal pressing, and has two side walls 42 interconnected by a plate 43.
  • the side walls 42 have three apertures formed therein.
  • the aperture 44 receives the pivot pin 23, the aperture 45 receives the pivot pin 40, and the aperture 46 receives pivot pin 47 (Figs.2,3) by which the second arm 22 is pivotably connected to the further arm 25.
  • Fig.8 shows the construction of the further arm 25.
  • the arm 25 is also a metal pressing, and has two side walls 48 interconnected by a plate 49.
  • the side walls 48 have two apertures formed therein.
  • the aperture 50 receives pivot pin 47 whilst the aperture 51 is adapted to receive a pivot pin 52 (Fig.2,3) so that the arm can be pivotably mounted to bracket 54 which is secured to the frame 3.
  • the plate 31 of the first arm 21, and the brackets 53,54 have mounting means by which they may be secured to the door hinge edge 4 and the frame hinge edge 7, respectively.
  • Such mounting means will preferably be a number of apertures for receiving a screw or other fixing, in known fashion.
  • the first arm 21 is secured to the door 2 and the brackets 53,54 are secured to the frame; this is expected to be the favoured arrangement.
  • the alternative use in which the first arm 21 is secured to the frame 3 and the brackets 53,54 are connected to the door is not thereby excluded.
