Definitions

  • the present invention relates to a door or window hinge, and more particularly to a hidden, concealed or invisible hinge that can be used for concealed rebated door or window applications.
  • Concealed hinges are known as a connecting element for mounting a door or sash to a frame.
  • different types of hinges are typically used for mounting rebated doors or sashes in comparison to flush mounted doors or sashes. This is due to the overlapping edge of the rebated door or sash which has to be accounted for in the hinge movement.
  • the sash has to be lifted off and away from the frame, while at the same time moving it back from the opening so that this overlapping edge is moved away from the clear opening in the frame.
  • hinges also allow for adjustment in 3 directions in a simple and convenient manner such that a precise side-to-side and up-and-down alignment of the door panel or sash parallel to the corresponding frame can be achieved for proper positioning as well as an in-and-out adjustment for proper sealing.
  • Embodiments of such a 3D-adjustable hinges are being shown in USD745363S, EP2997211 , US10246918B2 or EP3271538 respectively.
  • a rebate is a recess or groove cut into the edge of a piece of machinable material, usually wood. If two workpieces with rebates are being joined side by side in a matching or interlocking manner, the meshing area shall be designated as rebate section.
  • rebate section For illustrative purpose figure 11 shows two workpieces with rebates each and the rebate section marked with a circle.
  • a rebate section may include an air gap between the workpieces designated as shadow gap because it blocks the line of sight.
  • a rebate section shall be accomplished with sheet metal instead of massive workpieces, a rebate can be realized by twice folding an edge area of said sheet into a Z-shape resulting in an elongated area adjacent to the edge becoming relocated into a plane parallel to the original plane defined by the metal sheet.
  • Figure 12 d an embodiment of a rebate section established with two pieces of sheet metal is being shown. It shall be noted that in both examples shown in figures 11 and 12 d) the rebate section exhibit a flush appearance, i.e. the outer surfaces do not have steps but share a common plane. This kind of embodiment is called concealed rebate or false-flush fit.
  • a door or sash is a hinged barrier that allows access to and exit from a house or room.
  • the terms sash and door are being used interchangeably since technically, for the hinge, they have the same function.
  • a door may be moved in various ways, such as at angles away from the portal (swing door) in one direction (single action door) or two directions (double-action door) or by sliding in a plane parallel to the frame (sliding door).
  • Most doors however are hinged along one side to allow the door to pivot away from the doorway in one single direction, to the opening side.
  • the axis of rotation is usually vertical. In some cases, such as hinged garage doors, the axis may be horizontal, above the door opening.
  • the invention described hereinafter focuses on a frame-sash arrangement wherein the door or sash is allowed to pivot away from the frame in just one direction, the opening area (single-action door).
  • Such a concealed hinge is construed to mount a door or a sash to a frame, with a possible opening angle 0° ⁇ ⁇ ⁇ 180° between the open and closed position.
  • This hinge will comprise: A frame part as the hinge-related part of the frame, said frame part including a recess or pocket in or attached to the frame part and a pin or rotation axis R fixedly arranged within said pocket.
  • Hinge-related means in the technical context that the frame part will include only but all parts of the frame that are technically connected, related, affected or required for interfacing the hinge and the frame.
  • a hinge-related part of the sash designated as sash part will include a sash mounting part (mechanical interface between sash and hinge), wherein said sash part is being pivotable around said rotation axis R from the closed position via an opening pivoting range to an open position.
  • the sash will perform a single rotational movement in one direction, relative to the frame around the rotation axis when the door or sash is being opened.
  • a rebate section will include the neighboring portions of the frame part and the sash part; those parts do form a shadow gap in between them when the hinge is in closed state.
  • rebate section has been chosen, because the rebate section is per se not a single structural thing but an area (when viewed in cross section as in the figures) or respectively an arrangement of components from the frame part and the sash part which show a certain overlap in closed state.
  • the rebate section has a defined geometrical composition and comprises a sash part section with an essentially flat, plate-like element with a sash end point SEP.
  • the frame part section in turn comprises an essentially Z-shaped part with three plate-like sections. It goes without saying that both frame part section and sash part section are edge areas of frame and sash.
  • the first, inner section of said three sections is parallel offset from the second, outer section with a (connecting) intermediate web or third section in between.
  • the terms “inner” and “outer” mean “remote from a surface” and "at a surface”.
  • the Z-shaped part is geometrically defined by a frame end point FEP, a first frame bend point F1B and a second frame bend point F2B. Those bend points are thus arranged in or at the kinks of the Z:
  • the FEP and the F1B are being arranged in the first, inner section and the F2B is arranged in the second, outer section while the web or third section connects F1B and F2B.
  • a key element of the hinge is a rotational lever-arm which connects the frame part and the sash part. It exhibits, when viewed in cross-section, a hook-shaped contour, which can be described as comprising a loop shaped, circular segment rigidly attached to or integrally formed with a distance element.
  • This distinction is rather geometrical, not necessarily structural, because the lever arm is normally being formed as one piece for improved stability.
  • the open end of the distance element is being connectable to the sash mounting part and the open end of the circular segment is being attachable to the rotation axis.
  • the rotational lever-arm encompasses an enclosed clearance area F, which exhibits an essentially circle-segment shape.
  • the term "essentially” means here that the circle segment shape is not perfect in the sense of the standard geometrical definition. Further, encompassing is not to be understood in a way, that the lever arm is completely enclosing the clearance area from all sides (viewed in cross section).
  • Encompassing means a situation as shown in the drawings where the clearance area F is being located in the pocket or bend of the hook when the hinge is in a closed state. Clearance means, for the avoidance of doubt, the absence of any physical parts of the hook or lever arm in the area designated as clearance area F, when the concealed hinge is in its closed state.
  • the clearance area's shape can be defined by four corner points A, E, I', O' with circular arcs between A and E as well as I' and O' and straight lines between A and O' as well as E and I'.
  • a in this case is the point of the clearance area adjacent to point F1B (first frame bend point) and O' being the point adjacent to FEP (frame end point).
  • Adjacent is here to be understood as “located next to it while having the same radial distance to rotation axis R but offset by a small angular difference ⁇ in a direction against the opening rotation direction of the hinge".
  • the angle ⁇ is defined by the desired or required safety margin when construing the clearance area F.
  • corner points A, E, I', O' are being designated by vectors A , E , I ', O ' between the rotation axis R and said points, thus defining a polar coordinate system with the rotation axis R representing its zero position or origin.
  • the clearance area is the space where no part of the lever-arm is present when the hinge is in its closed state.
  • the geometry of the clearance area and especially the features of aforementioned vectors can be determined by three angles and the four vectors, especially it is valid that:
  • the concealed hinge can further be described with vectors A and E having the same first radial coordinate and vectors I ' and O ' sharing the same second radial coordinate (i.e. lengths relative to R), but A , E , I ', O ' having individual (different) angular coordinates.
  • the connecting lines between E and I' as well as A and O' do not intersect R.
  • the irregular circular segment A E I ' O ' can be reduced to a regular one designated A E I O .
  • the (simplified) clearance area can be described with vectors A and O having the same first angular coordinate and E and I sharing the same second angular coordinate.
  • Vectors I and I ' have the same radial coordinate as well as O and O '.
  • the difference of the angular coordinates between A / O and E / I is at least the opening angle ⁇ .
  • the connecting lines between E and I as well as A and O now do intersect R (A, E, I, O being the end points of vectors A E I O ).
  • the concealed hinge as described herein can be combined with means to achieve a 3D adjustability.
  • the hinge further comprises a sash pocket and two sliders.
  • the sliders which can move and slide are being held and guided in the sash pocket and in the sash mounting part.
  • the direction of motion between sash pocket and the sliders is chosen to be perpendicular to the direction of motion between the sliders and the sash mounting part.
  • the concealed hinge can be equipped with adjustment screws to adjust said directions of motion between sash pocket and the sliders as well as between the sliders and the sash mounting part.
  • the underlying functionality is later explained with the aid of figure 15 .
  • a major aspect of the invention is to simplify and secure the functionality of a concealed hinge with a hook-shaped rotational lever-arm by defining the clearance area which has to be factored in when designing such a hinge.
  • a method for construing a concealed hinge as has been structurally addressed above and explained in the drawings, will comprise the steps described below. It goes without saying that those steps are being described in a suggested, favorable, advantageous order. If some of the steps can be accomplished in parallel or in a different order without influencing the desired result, this shall be regarded as an equivalent approach.
  • the proposed steps consequently are: Defining an arrangement of a sash and a frame in a closed state, with the frame part and the sash part forming a shadow gap in a rebate section. Determining the position of frame end point FEP, first frame bend point F1B and sash end point SEP as has been explained in the structural description above and in the figures. Defining the position of rotation axis R for the hinge in the sash-frame arrangement. Determining the opening angle ⁇ between the open and closed position of sash and frame by pivoting SEP around rotation axis R from when the hinge is in its closed position to a position where SEP gets in contact with the frame at a sash-frame contact point SFC. This determination can be done by drawing or computer assisted, e. g. in CAD program.
  • E can be determined by pivoting vector A by at least said angle ⁇ against the opening rotation direction of the hinge.
  • a vector I ' with endpoint I' can be defined by pivoting vector O ' by at least said angle ⁇ against the opening rotation direction of the hinge.
  • the endpoints of A , E , I ', O ' define said clearance area F with an irregular circular segment shape having circular arcs between A and E as well as I' and O' and straight lines between A and O' as well as E and I'.
  • the hook-shaped rotational lever-arm can be construed between the sash mounting part and the rotation axis R in such a way that the material parts of the hinge in the closed state do not overlap or intrude the clearance area F AEI'O'.
  • a simplified clearance area AEIO can be determined in said polar coordinate system with center R.
  • Said clearance area has the shape of a regular circular segment, with further vectors O and I . Those are specified as follows:
  • the difference of the angular coordinates between A / O and E / I is at least the opening angle ⁇ . Then the hook-shaped rotational lever-arm between the sash mounting part and the rotation axis R can be construed in such a way that the material parts of the hinge in the closed state do not overlap or intrude the area AEIO.
  • Figure 1 shows an arrangement of a sash and a frame with a concealed hinge 10 in a cross section.
  • the frame part 100 is being shown on the left and sash part 200 on the right.
  • a recess or pocket 110 which is able to (at least) partially house a rotational lever arm 300 and its rotation axis, swivel pin 120 or the bearing for such a pin fixedly arranged within said pocket.
  • the swiveling motion can, in this arrangement, only be realized upwards (in the plane of figure 1 ), which is consequently addressed as opening area 60 (cf. figure 5 ).
  • the pocket 110 may therefore be manufactured as a metal housing receiving the rotation axis (or technically the bearing for the swivel pin) which is then arranged and mechanically fixed in the frame part 100.
  • the pocket 110 may exhibit a frame mounting part 130 which is e. g. screwed to the frame.
  • the frame mounting part 130 may, for example, be a mounting plate with several predrilled holes offering options to attach the pocket to the frame even for a variety of frames.
  • the hinge connects a frame and a sash by means of a hook-shaped rotational lever arm 300.
  • the arm is the mechanical link between frame part 100 and sash part 200.
  • the rotational axis of the lever-arm 300 is defined.
  • the other end of the lever-arm exhibits a sash mounting part 210, which may again be a mounting plate with pre drilled holes for screws or other fixtures to mechanically attach the sash part 200 to the lever-arm 300.
  • the contact area between sash and frame as shown in figure 1 exhibits an air gap or space 430 between them, which transitions into shadow gaps (for the upper part, 405).
  • rebate section 400 is being used to address this specific section, encircled in figure 1 .
  • the shadow gap 405 is being created by a rebated edge in the frame part 100 along the edge of sash part 200.
  • Sash part 200's edge is being realized by a projecting tongue 250 of metal partially overlapping or protruding into the rebated portion of the frame as shown for rebate section 400.
  • a corresponding tongue 150 is proposed for the other side of the sash-frame arrangement exhibiting a bracket-like structure 140 or 240 respectively. This bracket can be used to attach a gasket to seal the gap between sash part 200 and frame part 100 when the door is closed.
  • Figure 5 shows the opening movement of the sash with the rotational lever arm 300 from a closed position 20 to an open position 40 with snapshot swivel positions 30, 30', 30" in between.
  • the sash opens into the opening area 60.
  • the pivoting range 50 is equivalent to opening angle ⁇ .
  • Figure 4 shows a single, rotational lever-arm 300 with its characteristic hook shape.
  • the arm 300 can be described as having two functional parts separated roughly along the dashed line S: A loop- or C - shaped, (semi-) circular segment 310 and a distance element 320.
  • the length of the distance element 320 will vary depending on the geometrical ratios of frame and sash and is for the purpose of the invention a parameter, but not a variable.
  • the distance element's open end merges into the sash mounting part 210.
  • the open end of the C-shaped circular segment 310 bears the hinge axis 120.
  • the purpose of the hook shaped lever-arm 300 and especially the (semi-)circular design of element 310 is to provide a clearance area F (or 350) which is required for not colliding with elements of the rebate section 400. Simplified, the area F has the shape of a circular ring segment. Figures 7 , 8 and 9 will further explain details of this clearance area.
  • FIG. 1 The present invention defines the design limitations for such a concealed hinge in order to allow for improving the applicability and use of such hinges.
  • figures 2 and 3 show essential elements to understand the concept behind.

  • the triangles AO'O and E I' I have the same area and in conclusion the clearance area F has the same size for AEIO and AEI' O'.
  • Figure 6 tells us further that the limiting effect of point F1B is more pronounced than that of FEP, because during the pivoting motion of rotational lever-arm 300 F1B is more protruding than FEP from the perspective of the rotation axis R.
  • Figure 7 is basically figure 6 translated into polar coordinates.

  • the generalized clearance area AEI'O' can consequently be described, in a polar coordinate system with center R, as an irregular circular segment, with vectors A and E having the same first radial coordinate and vectors I ' and O ' sharing the same second radial coordinate wherein the difference of the angular coordinates between A / O and E / I is at least the opening angle ⁇ of the inventive hinge.
  • Figures 8 and 9 represent in summary the frame-sash arrangement with the essential geometrical parameters discussed above in detail with a view on figure 6 and 7 .
  • the translation of sash end point SEP into point Y (as used in figure 7 and 8 ) is shown.
  • SFC is the sash-frame contact at the maximum opening angle.
  • Figure 15 is an exploded view on a 3D adjustment component added to a single lever arm hinge 10.
  • the frame pocket 110 is being shown on the outer left with the rotational lever arm 300 detached.
  • Frame pocket 110 has two bushings 132, 134 to accommodate a pin 130.
  • Said pin 130 when the hinge is mounted properly, becomes the physical rotation axis 120 (R).
  • the sash mounting part 210 is here part of a complex workpiece facilitating the 3D-functionality.
  • 3D in this respect means an adjustability in three axes.
  • a first axis is called pressure adjustment 230 (230', 230"), since it is being used to increase or lower the contact pressure of the sash to the frame (e.g. against a gasket) in order to achieve a desired flush fit.
  • the three screws 230, 230'230" shown have a visible head, a respective threaded section anchored in the body of sash mounting part 210 and an eccentric shaft section (not visible) guided in a respective bushing in the distance element 320. This way a relative movement between lever-arm 300 and sash mounting part 210 can be accomplished. This degree of freedom is indicated by double-arrow near reference sign 230.
  • Sash mounting part 210 is being adjustably held in a sash pocket 220.
  • Said pocket is functionally equivalent to frame pocket 110. Both allow to properly provide a mechanically stable mount inside sash and frame, which both often are being manufactured from extruded aluminium.
  • Slider 260 is being guided once laterally in a recess 255; figure 260 shows a tongue and groove guide to allow for the lateral movement (arrow at lower slider 260'). Adjustability is being accomplished via a lateral adjustment screw 240, whose head is being designed to be received in a pocket 245. This screw will be stationary but rotatably held in place in recess 255.
  • the dotted line indicates the connectivity of slider 260, sash mounting part 210 and adjustment screw 240.
  • a respective tool can access the force application point of adjustment screw 240 via access 247. Turning the screw will move slider 260 back and forth within recess 245.
  • slider 260 (and 260') are being held in a channel or duct 265 which allows vertical movement (in the drawing plane, double arrow near reference sign 260).
  • Slider 260 has its counterpart 260' arranged upside down at the lower end of sash mounting part 210 with a comparable functionality as described for slider 260.
  • Slider 260 exhibits a ramp 275 with an inclined surface.
  • a grub screw 270 can be inserted via sash pocket access 277 and is held there in place by the threads.
  • the grub screw 270 has a conical tip and by turning it the conical tip will act on ramp 275 and force the slider into a downward move.
  • Counterpart slider 260' in return will force the slider (and attached sash mounting part 210 including lever arm 300) to go up, if required. If the desired final position of this vertical axis adjustment has been achieved, both screws can be used to secure sash mounting part 210 in its final position by clamping.
