Definitions

  • the invention described hereinafter refers to an adjustable monoaxial hinge for heavy load applications (typically up to 150kg) such as aluminium clad wood external doors/windows in a flush-fit design (i.e. the door or window is flush with the frame when closed).
  • a hinge has 2D all-mechanical adjustments and allows an easy and aesthetical installation without any need to mill or drill the door aluminum surface (i.e. in case of a door, the outside).
  • Said hinge is installed on the wooden surface behind the aluminum external cover so the outer protective cover remains intact.
  • the inventive hinge design has the advantage that nobody ill-intentioned can break down this hinge when the door/window is closed, because the fixation elements are not accessible from the outside.
  • Aluminium clad wood doors/windows are often installed on a building's external side (aluminium is preferred due to its improved resistance against the environment and for safety reasons) while the wood part provides favorable internal aesthetics.
  • a hinge basically includes at least 3 elements.
  • a central part defining the pivot axis including a bearing and an axial pin plus two blade shaped or (usually) flat fixing plates; one to connect the pivot part to a sash (sash part) and the other one to mount to a frame (frame part).
  • the sash in the broadest meaning can be part of a window, a door or any other functionally equivalent part of a building.
  • a hinge system according to this invention may include at least two hinges, which is especially suitable for doors of considerable weight, such as doors of wood with an exterior cladding of aluminium or other sheet metal.
  • one hinge of such a hinge system shall be described as inventive hinge. They can be used on either side of a sash (right or left hinged installation) and for any required position.
  • a hinge for pivotably connecting a sash of a door or window to a frame comprises a sash part designed to be attached to a sash, and a frame part intended to be attached to a frame. Said sash part and said frame part are interconnected by a pivot elemend which also defines a pivot axis.
  • the pivoting functionality is being accomplished by the pivot element via three bearing tubes, axially aligned along said pivot axis.
  • the first and the second bearing tube are being fixedly attached to the frame part and the third bearing tube is attached to the sash part.
  • the hinge axis itself providing the axial alignment is being realised by an axial pin extending through all three bearing tubes.
  • the third bearing tube can be be arranged and pivoatably held between the first and second bearing tube with axial play.
  • the free gap between between first and second bearing tube is larger than the length of the third bearing tube to allow for a adjustment along the pivot axis.
  • the axial pin exhibits an annular recess with a depth t.
  • the third (i.e. middle) bearing tube comprises, arranged at it's circumference, a radially aligned threaded hole with a diameter d intended for accomodating a locking screw. Said locking screw again is chosen in length and diameter to engage with the axial pin's annular recess, when mounted in said radially aligned threaded hole, thus locking the pin's axial position relative to the third bearing tube.
  • said threaded hole (arranged on the middle bearing tube) defines an axial hole axis along which the said locking screw is movable.
  • said axis will be arranged in a plane perpendicular to the bearing tube's longitundinal axis and will, further preferred, intersecting this axis.
  • the length of the screw is less important than the depth t of the resess and the diameter d of the screw.
  • the most preferred screw used for this locking screw will be a grub screw which can be screwed in flush or even countersunk. Most of those will use a head with a hexagon socket, to be used with a hex wrench or a respective angled tool. The limits given for distance x, a measure for the free space to insert a tool into the socket, will prohibit an easy removal of the grub (locking) screw with standard tools.
  • grub (locking) screw Depending on the dimensions of the hinge itself,
  • Cod (more narrow) values for x are d ⁇ x ⁇ 1.5 d or t ⁇ x ⁇ d.
  • Said hinge can further be construed such that said axial pin is being supported in bearing bushes in said bearing tubes.
  • the bearing bushes may be made from bearing metal, e.g. bronze.
  • a hinge's frame part comprises a bearing plate fixedly connected to the bearing tubes, and a so called box to be fixedly attached to the frame.
  • Said box again houses a cage and a slider.
  • the slider is being held in said cage by adjustment screws allowing for a lateral adjustment transversal to the hinge axis and that the slider is being fixedly attached via fasteners such as rivets to the bearing plate such that bearing plate can be laterally adjusted with respect to the cage.
  • the cage again may comprise a plurality of fixing holes foreseen to accommodate fasteners for fixing the cage to a frame.
  • a hinge according to the present invention is being fixed (normally) to a wooden frame planked with an outer aluminum cladding.
  • the frame will exhibit cut-outs, which can be milled e.g. during manufacturing of the frame.
  • the hinge's cage may exhibit at least two positioning pins such as bolt-shaped extensions on a surface of the cage to be in contact with the frame when the hinge has been mounted. Those bolt-shaped extensions will slide into respective bores in the cut-outs. Thus an easy and clear alignment of the hinge is being facilitated.
  • the cage comprises at least one threaded cross hole, arranged transversely to at least one the fixing holes and merging into said fixing hole.
  • the threaded cross hole is prepared for accomodating a safety grub screw.
  • the safety grub screw is intended to block the acess to the fixing screw(s) between frame part and frame. The grub screw can only be accessed when the door is in an open state, not when closed. Even removing the outer aluminum cladding will not help.
  • the axis of the threaded cross hole preferably does intersect the axis of the merged fixing hole.
  • the axis of the threaded cross hole and the axis of the merged fixing hole may be offset by a third of the diameter of the fixing hole.
  • a third safety feature hinge as described above may exhibit a sash part with at least one positioning pin extending from the bearing plate, away from the bearing tube, with a length chosen to be at least 30%, preferably 50% or more of the distance between the pivot axis and the sash part's mounting plane. Even when all screws are being removed connecting the sash part from the sash/door, the positioning pin, accomodated in a respective milled hole in the sash / door will be stuck. The reason is that the hinge only allows for a pivotal movement, however the pin can only be pulled out in a linear movement.
  • one of the first or second bearing tubes of the frame part exhibits an internal thread arranged at it's outer end.
  • This internal thread is being prepared to accommodate a terminal grub screw engaging with the internal thread. Said screw thus acts on a bearing bushing in said bearing tube allowing for axially adjustment of the position of the axial pin.
  • the hinge can be adjusted in height (sash relative to frame).
  • the slider 140 is supported slidably in one (lateral) direction in said cage 130.
  • the slider 140 can be shifted by means of lateral adjustment screws 142 within the cage's 130 recess 137. Since the slider 130 is connected with the bearing plate 116 via rivets 112, any adjusting movement of the slider is being transferred directly to the bearing plate 116. By that, the relative distance between a sash 109 and frame 103 can be effectively adjusted.
  • the locking grub screw 134 can then block the relative movement and secure the adjusted position the slider relative to the cage after adjustment has been accomplished.
  • the "openings for passage of screws for fixing box to frame" 114 as shown in figure 2 are not meant to fixedly connect the bearing plate 116 ( Fig. 3 ) to a frame 109. They only allow access to the fixing holes 136 in cage 130.
  • Figures 3 and 4 clearly show that it is the box 117, notably the cage 130, that is being attached to a frame 109.
  • the cage 130 / box 117 is to be placed in a recess milled out of the (wooden) frame 109.
  • Safety grub screws 132, placed in threaded cross holes 138 of the cage body can block access to the fasteners in the fixing holes 136.
  • Figure 5 shows a view on a inventive hinge 100 from the sash 103 / frame 109 side.
  • Both frame part 110 and sash part 120 show positioning pins 124, 119.
  • Their counterparts can be drilled or milled from the frame/sash material e.g. with the aid of a drill template to warrant a correct position within the structural element.
  • Figure 6 shows a straight view on a hinge 100 similar to the view of figure 5 . This figure is being displayed to show the lateral adjustment range of the slider 140 relative to the cage 130. A gap 114 or 145 respectively mark the clearance left after the slider 140 has been moved to one of the respective outer positions in the cage's 130 recess 137. The arrow shows for both cases where the slider touches the stop.
  • Figure 7 shows the adjustment range 106along the pivot axis 150. As mentioned above, this adjustment is being accomplished by means of a terminal grub screw 158 (not visible in Figure 7 ) interacting with a respective thread 155 foreseen in the bearing tube(s) 118', 118 of the frame part 110. The adjustment can be accomplished by an allen key which matches a respective recess or socket in the grub screw 158.
  • Figure 7 show the respective upper 102 and lower 101 position (arrow) and the gaps 104, 105 representing the vertical adjustment range.
  • Figures 8 and 9 display an important safety feature of this inventive hinge design.
  • a grub screw 132 is arranged in the body of the cage 130.
  • the orientation of the threaded hole is inclined, preferably rectancular to the axis of the fixing screw used to attach the cage / box to the frame.
  • the axis of orientation of the threaded hole (125, cf fig.14 ) and the axis of orientation for the target position of the fixation screw preferably intersect.
  • the grub screw 132 can only be properly removed, if the hinge is in its "open" position. In other words, a burglar trying to dissasemble the hinge to gain access to a building cannot do so by simply using a screwdriver.
  • FIG 10 Another safety feature is being shown in figure 10 :
  • the bearing tube 128 arranged on the sash part 120 exhibts a threaded cross hole 125 (cf. fig. 14 ) for a grub screw 126.
  • This grub screw will interact with the annular recess 152 in the hinge pin 151.
  • the position of the cross hole 125 on the bearing tube 128 will be chosen such that it cannot be accessed while the hinge is in the "closed" position, but is accesible in the open position.
  • the grub screw 126 does that way not block the pivoting movement and also not the possibility for the vertical adjustment as shown in figure 7 .
  • the sash part 120 and the frame part 110 will be arranged in such a way that their bearing tubes 118, 118', 128 align and the pin / pivot axis 151 can be inserted. It will be positioned such that the grub screw 126, inserted in the cross hole 125 of the sash part's 120 bearing tube 128 can engage the annular recess 152 in the pin 151. As a third step the terminal grub screw 158 for the vertical adjustment can be inserted in the (lower) end of the frame parts 110 bearing tube 118 or 118'.
  • Figure 11 and 12 shall exemplify how the inventive hinge is being installed in a wooden frame 109 / sash 103 cladded with aluminum 108 (sheet metal).
  • the frame part's fixation screws (not shown) are being protected by a blocking grub screw(s) 132 as exhibited in figure 9 .
  • Dissassembly of the hinge axis (pin) 151 is blocked by the grub screw 126 shown in figure 10 .
  • the sash part 103 seems to be removable, because the flat metal plate cannot accommodate a mechanism like the frame part 110 ( figures 9 , 10 ).
  • the positioning pin 124 shows a considerable length.
  • FIGS. 11 and 12 also show gaskets 107 arranged between frame 109 and sash 103.
  • FIG. 13 shows the sash part 120 separately with positioning in 124.
  • the hinge axis 150 lies within a transvese plane 150 defined by the angled part of sash part 120.
  • the threaded hole 125 defines a hole axis 127 which defines an angle ⁇ with the transverse plane 123.
  • Figure 14 is a view straight on hinge axis 150, the threaded hole 125 together with hole axis 127 has been shown with its diameter d.
  • hole axis 127 will intersect with hinge axis 150 in bearing tube 128.
  • the distance x is the distance between the outer circumfeerence if the bearing tube 128 at the location of threaded hole 125 and the intersection of hole axis 127 with the surface of outer (aluminum) cladding 108.
  • the whole arrangement of the hinge as described above can be realised with manufacturing techniques known in the art, with milled and cold formed parts arranged and welded according to design; screwed, welded, riveted or bolted together as required.
