Definitions

  • the current invention relates to a window assembly comprising a window frame, a window sash and a hinge assembly, where the hinge assembly comprises: a track having a first end and a second end and being fastened to the frame with the longitudinal axis of the track being arranged parallel with the plane of the window frame, a slider fastened to the sash near one corner of the sash and arranged such that the sash is pivotable with respect to the slider about a pivot axis, said slider being slideably arranged on the track, thereby allowing the sash to slide along the track and a first link having a first end and a second end, said first end being pivotably fastened to the frame about a pivot axis arranged at a location on the frame between the first and second end of the track and/or a second link having a first end and a second end, said second end being pivotably fastened to the sash about a pivot axis,
  • bracket assembly should in the context of the current invention be understood as a form of bracket or fitting or linkage which can be attached to the frame of the window assembly and which can be used to provide a defined form of motion to the window sash with respect to the window frame.
  • a hinge assembly for a reversible window assembly i.e. a window assembly which can be reversed about its horizontal axis or its vertical axis to bring the outer surface of the window in to face the inside of the window assembly in order to allow the outer surface to be cleaned.
  • a side hung projecting window where a combined sliding and pivoting motion is used.
  • a reversible fitting for a window which pivots about its horizontal axis is disclosed in the figures, however the scope of protection should include other forms of fittings/hinge assemblies as well.
  • a second aspect of the current invention is to provide a window assembly and a hinge assembly which can be hidden completely behind the sash in the closed position of the window assembly and/or which does not require any cutouts in the sash.
  • a window assembly as mentioned in the introductory paragraph further comprising a first displacement mechanism arranged on a profile element of the window frame and arranged to displace the first end of the first link when the slider slides along the track, the direction of said displacement having a vector component which is perpendicular to the longitudinal axis of the track, parallel to the plane of the window frame and away from the centre of the window frame and/or a second displacement mechanism arranged on a profile element of the window sash and arranged to displace the second end of the second link when the window sash is pivoted with respect to the second link, the direction of said displacement having a vector component which is perpendicular to the longitudinal axis of the sash profile element to which the second displacement mechanism is connected, parallel to the plane of the window sash and away from the centre of the window sash.
  • This motion allows a more flexible design of the window assembly since the first link and/or the second link can be displaced during motion of the link, in addition to the rotation which is typical for such links.
  • this invention is suitable for window assemblies where a component or portion of the window assembly overlaps or partly overlaps with the first link and/or the second link in the closed position of the window assembly when looking at the window assembly perpendicular to the plane of the window assembly, but where the overlapping component or portion needs to pass the first link during the desired motion of the window sash.
  • the provision of a displacement mechanism is suitable since the first link and/or the second link can be displaced to allow the overlapping component or portion to pass the first link and/or the second link.
  • the component or portion of the window assembly which overlaps the first link and/or the second link could be the window sash, another link of the linkage, a sliding element, etc.
  • a link should be understood as a physical member, typically an elongated member, which is pivotably connected to other elements via at least two pivot points. It should be noted that “the end” when used in the phrase “the end of the link”, should be understood not necessarily as the physical “end” of the physical member, but rather as the point of the pivotable connection, the actual physical member could extend past the point of pivotable connection.
  • the sash, the first link and the pivot axis between the frame and the first link could be arranged such that the first link is at least partially hidden behind the sash in the closed position of the window assembly when looking at the window assembly from the outside of the window assembly and in that the displacement of said first displacement mechanism is large enough so that the window sash is able to pass by the first link when the window sash is moved from a position where the slider is on one side of the pivot axis between the frame and the first link to a position where the slider is on the other side of the pivot axis between the frame and the first link.
  • the hinge assembly could be arranged such that the displacement occurs when the slider is moved from a position where the slider is at one end of the track to a position where the slider is at the other end of the track.
  • the first link could also be connected to the sash either directly or via one or more links.
  • directly is meant that the first link is in some way pivotably, displaceably and/or rigidly fastened to the sash.
  • via one or more links is meant that one or more links are arranged between the first link and the sash. In both cases, motion of the sash will cause motion of the first link and vice versa.
  • the displacement of the displacement mechanism could be provided via a ramp element which causes a displacement upon rotation of the displacement mechanism.
  • a screw mechanism is considered to be a form of spiral ramp mechanism for the sake of this specification.
  • the slope of the ramp mechanism the displacement to motion ratio is easily determined.
  • different functions can be easily integrated into the displacement mechanism. For example a rising portion followed by a straight portion could be provided to allow a displacement along the rising portion and then a zero displacement along the straight portion.
  • the displacement mechanism is "arranged to displace the first end of the first link when the slider slides along the track". This should however not necessarily be interpreted in that the motion of the slider causes the displacement.
  • the displacement itself can be caused by rotation of the link with respect to the frame, by displacement of the link with respect to the frame, by displacement of the sash with respect to the frame and many more combinations. The above description should therefore be interpreted in that the displacement occurs when the slider slides along the track, but not necessarily due to the slider sliding along the track.
  • the displacement does not necessarily occur during the entire motion of the slider along the track.
  • the motion could occur during only a portion of the sliders motion along the track. For example, it could be that between 0 and 25% of the travel of the slider, no displacement is caused, followed by displacement during 25%-75% of the travel of the slider, then no displacement during 75% to 100% of the travel of the slider.
  • the displacement of the displacement mechanism will have the mentioned direction when the slider slides along the track in a first direction. When the slider slides along the track in the opposite direction, the direction of the displacement will be opposite.
  • the window assembly could comprise two hinge assemblies as described, one arranged on either side of the window assembly, said two hinge assemblies being arranged such that the first and/or second displacement mechanisms of the two hinge assemblies are arranged oppositely so that the two first ends of the links are displaced away from each other during motion of the sash.
  • two hinge assemblies are mounted at the sides of the window assembly.
  • a window assembly according to the current invention by providing a hinge assembly at the top and bottom sides of the window assembly where the window opens about a vertical axis.
  • the current invention is mainly related to a new type of hinge assembly. As such the scope of protection should extend to the hinge assembly itself and not just to the completely assembled window assembly.
  • the window assembly comprises a hinge assembly.
  • the window assembly comprises at least one hinge assembly.
  • Figures 1-6 show different views and configurations of a first embodiment of a window assembly 1 according to the current invention.
  • Figures 1-6 all show a single hinge assembly 2 mounted on one side of the window assembly. It should however be noted that the hinge assembly shown in the figures is of the kind which is designed to be used as a pair, i.e. one mounted on each side of the window assembly. Only one hinge assembly has been included in the figures for the sake of clarity.
  • the window assembly comprises a window frame 3, a window sash 4 and a window pane 5.
  • the window frame is made up of four frame profile elements 3a, 3b, 3c and 3d.
  • the window sash 4 is made up for four sash profile elements 4a, 4b, 4c and 4d.
  • the profile elements are joined at their ends into rectangular assemblies having four corners, where the corners refer to the location where the ends of the profile elements meet.
  • the window pane 5 is joined to the window sash.
  • the hinge assembly 2 connects the window frame and the window sash.
  • the currently depicted hinge assembly is of the kind which is typically called a hinge assembly for a "reversible window assembly", i.e. one which can be "reversed” to make cleaning easier.
  • the hinge assembly comprises a first link 10, a second link 11 and a third link 12.
  • the first link 10 has a first end 10a pivotably connected to the frame about a first pivot axis P1 via a first pivot assembly 14.
  • the second end 10b of the first link is pivotably connected to the first end 11a of the second link 11 about a second pivot axis P2.
  • the second end 11b of the second link 11 is pivotably connected to the sash about a third pivot axis P3 via a second pivot assembly 16.
  • the second end 12a of the third link 12 is pivotably connected to the second link 11 about a fourth pivot axis P4 located between the first and second ends 11a, 11b of the second link.
  • the first end 12b of the third link 12 is pivotably connected to the frame about a fifth pivot axis P5 located at a fixed pivot mechanism 20.
  • the hinge assembly further comprises a track 25 which is fastened to the front surface of one of the side frame profile elements 3b.
  • the track has two ends 26,27 and extends along the entire length of the side profile element.
  • a slider 28 is slideably mounted on the track.
  • the slider is furthermore pivotably connected to one corner of the window sash about a sixth pivot axis P6.
  • the sash is therefore able to displace up and down along the axis of the track.
  • due to the arrangement of the links as the sash is displaced up and down, the sash is also displaced outwardly and caused to pivot as shown by comparing figures 4-6 .
  • the window sash and frame are of particular interest to the current invention.
  • the window sash completely overlaps the window frame. Therefore, there is no gap between the frame and sash in which the links of the hinge assembly can move during the sash reversing process.
  • the first link is completely hidden behind the sash in the closed position of the window. No cutouts or other forms of adjustments have been made to the front surface of the window sash. In the closed position of the current window assembly, a viewer looking at the window assembly from the outside would only see the window pane and the outer surface of the window sash. This provides for a very "clean" visual impression.
  • the corner of the window sash which is connected to the slider must pass the first and third links.
  • Especially passing the first link would not be possible with prior art type hinge assemblies if the first link were at least partially hidden behind the sash in the closed position of the window as the sash would otherwise collide with the first link during the reversing procedure.
  • the first link and the third link can be displaced outwardly away from the sash, thereby allowing the sash to pass the first link.
  • first and second pivot assemblies 14,16 are described in more detail with reference to figures 8 and 9 respectively. It should be noted that the pivot assemblies described in figures 8 and 9 have both a pivot and a displacement mechanism. In the claims, the term “displacement mechanism" is used to refer to the first and second pivot assemblies since the action which is most relevant with respect to the current invention is the displacement, however, it would be most correct to call the pivot assemblies of the current embodiment for "pivot and displacement mechanisms" or "pivot and displacement assemblies”.
  • the first pivot assembly 14, shown in figure 8 comprises a housing 30 and an axle member 31.
  • the housing is made up of a core element 32 and a sheet metal outer "skin" 33.
  • the sheet metal outer skin provides the strength for the housing.
  • the core element could for example be injection moulded.
  • the sheet metal outer skin comprises two parts 33a, 33b which are riveted 34 together.
  • a metal cylinder 35 is arranged and supported inside the core element.
  • the housing could be cast as a single element, for example in aluminum or zinc.
  • the axle member 31 comprises a slot 36, having a straight part 36a and an angled part 36b.
  • the axle member further comprises an engagement member 37 for engaging with the first end 13 of the first link 10.
  • the engagement member 37 is formed with a cylindrical portion 38 and a key portion 39.
  • the first end of the first link is formed correspondingly.
  • the first end of the first link is placed onto the cylindrical portion 38 and the key 39 aligned with a slot 40 in the first end of the first link.
  • the cylindrical portion is then deformed like a rivet to firmly join the first link to the axle member of the first pivot assembly.
  • the axle member When the pivot assembly is assembled, the axle member is placed inside the metal cylinder 35 inside the core element and sheet metal skin portion. A pin 41 is then passed through the outer skin, the core, the metal cylinder and the slot in the axle member. The elements are now locked together. Due to the form of the slot 36, when the axle member is rotated due to the rotation of the first link 10, the axle member will either displace outwardly away from the frame member (if the pin is in the angled part 36b of the slot) or will purely rotate (if the pin is in the straight part 36a of the slot).
  • the first link pivots outwardly.
  • the first link stops pivoting outwards. Further motion of the sash to the fully reversed position pivots the first link inwardly again.
  • the first link displaces outwardly while during the second half of the motion of the sash the first end of the first link displaces inwardly again.
  • a more complex displacement mechanism could be provided where the first end of the first link maintains its outwardly displaced position or keeps displacing outwardly while the sash progresses from its 90 degree position to its fully reversed position.
  • the frame comprises a forwardly protruding flange.
  • the first pivot assembly 14 has been placed in a recess provided in the forwardly protruding flange. This recess could be provided by machining a recess in the flange after manufacture of the frame element.
  • the first pivot assembly can be mounted directly to the frame element without the need for a recess, or be placed only partly in a recess in the thin protruding flange.
  • the second pivot assembly can be seen in more detail.
  • a housing 50 is provided and attached to the sash.
  • the housing comprises a cylindrical opening 51 which can accept an axle member 52.
  • the axle member is non-pivotably connected to the second end 16 of the second link 11.
  • the axle member is furthermore formed with a spiral ridge 53 which fits with a spiral groove 54 on the inside of the cylindrical opening 51. As the housing pivots with respect to the second end of the second link, the axle member will displace outwardly.
  • the first pivot assembly was arranged with a pin in a slot and the second pivot assembly was arranged with a spiral ridge in a spiral groove.
  • many options are possible.
  • the motion of the housing will keep rotating in the same direction for the entire motion of the window sash. Therefore, during the entire motion of the window sash, the second end of the second link will displace outwardly. In this way, when the sash is in its fully reversed position, the second end of the second link will be fully displaced outwardly.
  • a sliding element 70 is provided at the corner of the sash. This sliding element is shown in more detail in figure 10 .
  • the sliding element is made from a material with a low coefficient of friction which allows the friction between the contact between the sliding element and the first link to be reduced. Furthermore, the sliding element ensures that the first link does not come into direct contact with the sash. Direct contact between the sash and the first link could cause damage to the sash, for example scraped paint.
  • the sliding element 70 is shown to extend only a short distance along the sash profile element. However, depending on the arrangement of the sash and frame, the sliding element could in certain embodiments also extend further along the sash profile element. In one example, the sliding element extends along at least 25% of the length of the sash profile element. In another example, the sliding element extends along at least 50% of the length of the sash profile element.
  • a first displacement is due to the displacement of the first end of the first link via the first displacement mechanism.
  • a second displacement is due to the displacement of the second end of the second link via the second displacement mechanism.
  • a third displacement is due to the displacement of the first link and the third link via the sliding element 70 which presses the links outwardly.
  • the first displacement could be used alone.
  • the second displacement could be used alone.
  • the third displacement could be used alone.
  • any combination could be used, for example first and third, or second and third, or first and second.
  • the second end of the first link would also be displaced outwardly. Therefore only the first end of the first link would need to be thinner. In order to maintain the strength of the first link, the first end of the first link could be made wider. It should be noted that by thickness is meant the dimension of the link which is parallel to the plane of the window assembly and perpendicular to the longitudinal direction of the link and by width is meant the dimension of the link which is perpendicular to the plane of the window assembly and to the longitudinal direction of the link.
  • the embodiment of figures 1-10 also comprises an additional feature which is difficult to see from the figures, but which should be mentioned.
  • the portion of the third link 12 which overlaps with the first and second links in the closed position of the window assembly is slightly twisted along its longitudinal axis.
  • the portion is twisted approximately 10-15 degrees from the plane which is perpendicular to the window assembly and parallel to the longitudinal axis of the hinge assembly (or at least the longitudinal axis of the track).
  • the twist is arranged such that the edge of the third link which faces the first link is twisted away from the first link and the edge of the third link which faces the second link is twisted away from the second link in the open position of the window assembly.
  • the hinge assembly comprises a first link and a third link where the third link is pivotably fastened to the first link, arranged on one side of the first link and twisted along its longitudinal axis such that the edge of the third link which faces the first link during normal use is twisted away from the first link.
  • a link which needs to pass beside another link like the third link in the current embodiment which needs to pass the first link, would have a certain thickness and its edge be rounded such that if the link was not perfectly aligned beside the other link during the closing motion, the link would align itself beside the other link due to the rounded edge.
  • the third link in the current embodiment is provided with a twist.
  • the twist ensures that when the third link approaches the first link, even if the third link overlaps the first link slightly, the twist will push the third link to the correct side of the first link and prevent the third link from blocking on the first link. It should be noted that this feature could be used with other types of fittings and not just with the fitting described in the current embodiment or the current claim set.
  • Figure 11 shows a second embodiment (100) of a window assembly and hinge assembly.
  • the window assembly comprises a window frame 101 comprising four window frame profile elements (101a,b,c,d).
  • the left window frame profile element (101a) has been removed in order to better see the details of the displacement mechanism.
  • a window 102 sash is supported in the window frame via the hinge assembly 103.
  • the hinge assembly has the same function as the hinge assembly 2 of the first embodiment and therefore the function will not be described more here.
  • the main difference between the two embodiments is in the function of the displacement mechanism 110 connected to the first link 111.
  • the details of the displacement mechanism can be explained by reference to figures 12 and 13 . Please note that the housing of the first displacement mechanism 110 as can be seen in figure 11 has been removed in figure 13 in order to show the details of the displacement mechanism.
  • the displacement mechanism 110 comprises a linear gear (112) and a rotary gear (113).
  • the linear gear is arranged displaceably in a groove 114 which is arranged parallel to the longitudinal axis of the track 115 of the slider 116.
  • the linear gear is sandwiched between two elements, where one of the elements has been removed in the figures to show the linear gear and the groove.
  • a pivotable tab 117 is connected to one end of the linear gear. The pivotable tab is arranged such that when the slider 116 is slid down the track 115, the slider engages the pivotable tab at a certain position of the slider and then pulls the pivotable tab and the linear gear long with it.
  • the linear gear 112 is engaged with the rotary gear 113 and when the linear gear displaces, the rotary gear 113 rotates.
  • An axle 118 is further engaged with the rotary gear.
  • a screw mechanism (not shown) is arranged between the axle and the rotary gear, such that when the rotary gear rotates and the axle is held in a fixed angular position, the axle will displace with respect to the rotary gear.
  • the end of the axle is non-rotatably fastened to the first link such that the first link holds the axle in a relatively fixed angular position. As the axle displaces, the end of the first link is therefore also displaced.
  • the pivotable tab pivots away from the slider, thereby allowing the slider to disengage from the pivotable tab and continue its motion without further displacement of the linear gear.
  • the groove in which the linear gear displaces has a bent portion 119 at each end which steers the motion of the pivotable tab 117.
  • the displacement of the end of the first link can be precisely controlled. For example by choosing the slope on the screw mechanism, the displacement of the first link can be increased or decreased in a simple manner. Furthermore, the link stays fully displaced (or even continues its displacement) while the sash is going from its 90 degree position to its fully reversed position. Due to this, in this embodiment it is not necessary for the second link to be displaced and there is no need for a sliding element as in the first embodiment since the first link will stay displaced during the entire reversal procedure of the sash. However, a second displacement mechanism or a sliding element could be introduced if desired.
  • the slider could comprise a first ramp which pushes the pivot point of the first link outwardly when it is slid past the first pivot point.
  • many different embodiments are possible.
  • hinge assemblies for reversible window assemblies.
  • other forms of hinge assemblies could also be considered relevant for the current invention.
  • a side hung, side projecting window could also be relevant.
