Definitions

Such a hinge is known in the art and used for a pivotal window, e.g. a roof window installed in an inclined roof surface, to provide a pivoting movement, i.e. the sash turning about a hinge axis at a distance from the top and bottom member, alternatively the side members, of the sash and of the frame.
the hinge comprises two extreme positions, between which one, a plurality or a continuum of intermediate positions is defined.
the extreme positions include a position in which the pivotal window is closed and a position in which the window sash and thus the second hinge part is turned outside at a maximum in relation to the closing position.
both extreme and intermediate positions of the window it is desirable to have the window remain in the set position, such that the window does not unintentionally pivot by internal or external forces after setting the position of the window.
Internal forces may for instance be the weight of the window, and external forces may for instance be wind loading.
Prevention of unintentional pivoting caused by internal forces can be achieved by providing enough friction in the hinge to overcome the pivotal moment of the window, i.e. the opening and the closing moment, for the range of desired intermediate positions.
the opening and closing moment of the window depend among others on the roof angle and the type of window.
the hinge friction cannot overcome the pivotal moment and as such these intermediate positions are unstable.
the tensioning projection of the guide pin may, during at least a part of the pivoting movement, be positioned to face the slide bar, potentially a leading end of the slide bar. Additionally or alternatively, the tensioning projection of the guide pin may form a tip end of the guide pin. Additionally or alternatively, the tensioning projection may form a trailing portion of the guide pin during the closing movement of the window.
the leaf spring may, during at least a part of the pivoting movement, be in a frictional engagement with the convex side of the guide pin and/or the tensioning projection of the guide pin. This may provide the advantage that a relatively large surface is used for the frictional engagement and thus stress spikes during the pivoting movement of the window may be reduced.
the guide pin may comprise a nose, potentially positioned on an opposite side of the guide pin relative to the tensioning projection.
the nose may extend at the concave side of the guide pin.
a side of the nose may be integral and/or continuous with the concave side of the guide pin.
the nose may comprise a side adjacent to the concave side of the guide pin and may form an integral and/or continuous surface, which may be configured to press against a side, potentially a concave side, of the guide opposite the leaf spring during at least a part of the pivoting movement of the window.
a distance between the tensioning projection of the guide pin and the slide bar along a tangential direction of a convex side of the guide, when the window is in the closed position is less than 10 mm, preferably less than 5 mm, more preferably less than 2 mm. It is understood that the distance is measured along a tangential direction of a convex side of the guide wherein the curvature of the convex side of the guide is extended towards the guide pin.
the distance is measured along the circular arc of the convex side of the guide.
the leaf spring further includes a plurality of portions; a first end portion connected to a first curved portion connected by the elbow portion to a second curved portion connected to a second end portion, wherein the first end portion being adapted to connect to a first pin of the first hinge part, and wherein the second end portion being adapted to connect to a second pin of the first hinge part.
the first curved portion and the second curved portion are preferably circular arc shaped. This has the advantage that the leaf spring can be configured to desired levels of friction at various intermediate positions of the window, such that friction is increased as desired at intermediate positions.
the leaf spring is adapted to abut a third pin of the first hinge part during at least part of the pivotal movement of the window. This has the advantage of allowing the leaf spring to further stiffen and thus provide additional friction at certain intermediate positions.
the first and/or the second curved portion of the leaf spring in particular the curvature thereof, is/are adapted such that the leaf spring is in a frictional engagement during the pivotal movement of the window.
the guide pin is non-rotatably mounted to the second base plate such that the guide pin is not allowed to rotate in relation to the second base plate. This has the advantage that the orientation of the guide pin is known throughout the pivoting movement of the hinge such that the friction caused by the guide pin can be configured accurately.
the guide pin has a droplet shaped cross section in a cross-sectional plane normal to the hinge axis.
the guide pin comprises a coating, in particular a polyolefin coating, adapted to reduce the wear of the frictional engagement.
circular arc is understood to constitute a part of the circumference of a circle.
circular arc shaped is understood to constitute the shape or outline of an element when viewed from a cross-sectional plane normal to the hinge axis.
Figs 1 to 6 a general overview of the components of a hinge according to the invention will first be given.
the hinge is configured to be installed in a pivotal window with a frame and a sash connected to the frame.
the hinge is configured to provide a pivoting movement for the window in that the sash is able to turn relative to the frame about a hinge axis represented by reference numeral 17 in Figs 4 to 6 .
the slide bar has a concave side 8b, a convex side 8c and a hinge end 8d connected to a hinge pin 9 mounted on the second base plate 4. Finally, a stop pin 9a is provided on the base plate 4 as in traditional hinges.
the slide bar is here provided with a leading end 8a with a surface 8e to be accommodated by a gap surface 10d of the guide pin 10 to be described in further detail below.
the leaf spring 15 is, during at least a part of the pivoting movement, in a frictional engagement with at least one element of the engagement set of the second hinge part 3. Which part depends on the actual position of the element in question.
the leaf spring 15 includes at least one elbow portion 15c and the guide pin 10 comprises a tensioning projection 10a.
the guide pin 10 has a cross section shaped as a droplet, in which the tensioning projection 10a is associated with a concave side 10b and a convex side 10c opposite the gap surface 10d.
the material of the guide pin 10 is chosen to provide the frictional and wearability properties aimed at, and is typically made of steel.
One specific material that has proven to function well is the commercially available VN 24.H20005.96.
the leaf spring may be provided according to the EN 10270-1 standard and is typically made of steel.
the distance may be chosen according to the specific field of application of the hinge; typically, the distance is less than 10 mm. preferably less than 5 mm, more preferably less than 2 mm.
the slide bar 8 and the guide pin 10 define a gap 16 comprising a central section 16a having substantially parallel edges and preferably a width less than 5 mm, more preferably less than 3 mm, even more preferably less than 2 mm.
the leaf spring 15 includes a plurality of portions. These portions include a first end portion 15a connected to a first curved portion 15b connected by the elbow portion 15c to a second curved portion 15d connected to a second end portion 15e.
the first end portion 15a is adapted to connect to a first pin 5a of the first hinge part 1
the second end portion 15e is adapted to connect to a second pin 5b of the first hinge part 1.
the first curved portion 15b and the second curved portion 15d are preferably circular arc shaped.
the second end portion 15e is adapted to connect to a second pin 5b of the first hinge part 1 in an operation position and in an assembly position, the operation position being the position of the pin when the window is in a mounted state, and the assembly position being a position where the connection and/or disconnection of the first end portion 15a to the second pin 5b is allowed.
the specific shape of the leaf spring 15 along the path from one end to the other will typically be chosen according to the requirements to the hinge in accordance with factors such as the size and weight of the components of the window, most importantly the weight of the pane and the sash.
the centre of curvature of the first curved portion 15b is different from the centre of curvature of the second curved portion 15d.
the radius of curvature of the second curved portion 15d is in the interval of 80 - 160 mm, preferably in the interval of 100 - 140 mm, more preferably in the interval of 110 - 130 mm.
this may in principle be chosen in any suitable manner, ranging from a radius of curvature smaller than the second curved portion 15d up to substantially straight.
the radius of curvature is larger than 70 mm, for instance 74 mm.
this second embodiment of the guide pin 10 corresponds to the first embodiment except in that, this second embodiment of the guide pin 10 includes a nose 10g positioned on an opposite side of the guide pin 10 relative to the tensioning projection 10a.
the nose 10g comprises a side adjacent to the concave side 10b of the guide pin 10 and forms an integral and continuous surface, which is configured to press against a side of the guide 7 opposite the leaf spring 15 during at least a part of the pivoting movement of the window.
the nose 10g extends less than the body 10f of the guide pin 10 in a direction of the hinge axis so that the nose fits in a spacing between the plate piece 6 and the first base plate 2 when the hinge is in the closed position.
Figs. 10 to 13 are graphs showing computer simulated curves for the hinge moments in Nm relative to the opening angle degree are shown for various roof inclinations.
the dashed and the dotted lines respectively indicate the hinge moment in the closing direction and in the opening direction.
the solid lines indicate the sash moment when a roof window is installed at various different roof angles.
the hinge friction in the closing direction should be greater than the sash moment, while the hinge friction in the opening direction should be lower than the sash moment.
the hinge friction in the closing direction drops below the sash moment which causes the window to close.
Fig. 13 shows the improvement in hinge friction when incorporating a hinge according to the invention in a roof window with the sash moment characteristics as shown in Fig. 12 , where the hinge incorporates only a new guide pin and an existing leaf spring.
the hinge friction in the closing direction now stays above the sash moment at 15 degrees for all opening angles.
the negative moment of the hinge friction in the opening direction is increased such that it falls below the sash moment at a 90 degree roof angle at an opening angle of about 30 degrees.
a new guide pin provides the desired friction, while the combination of a guide pin and a leaf spring according to the invention may provide additional friction.
