Description

TECHNICAL FIELD

The present invention relates to a frame assembly comprising profiled frame pieces for a hinged unit. The frame pieces are of the type which has a raised part constituting a shoulder arranged to be in contact with the hinged unit in a closed position. The frame assembly, when in a position for use, consists of a first long piece extending vertically in the Y-direction and a sill extending horizontally in the X-direction.

PRIOR ART

Hinged units in the form of doors and windows, for example, are used in houses and other buildings. The hinged units are mounted in a frame assembly consisting of a sill with two ends present on the floor of the house and two long pieces extending vertically from either end of the sill, each of which pieces is also arranged at the corresponding short end of a head piece opposite to the sill. The various component parts are usually profiled in such a way that a shoulder runs on the inside of the frame assembly, which shoulder constitutes a sealing strip against the hinged unit in a closed position.
In a house or other building, a number of doors and a number of windows are so arranged as to be opened by causing them to rotate in an anti-clockwise direction (right-hung), while others are so arranged as to be opened by causing them to rotate in a clockwise direction (left-hung). This is achieved by mounting the hinges on which the hinged unit is hung either on the right-hand long piece (right-hung) or on the left-hand long piece (left-hung). In order to be able to use the same shell for a frame assembly, it has previously been proposed to provide the frame assembly with specially executed end sections on the long pieces, which end sections are intended to fit into corresponding specially adapted parts of both the sill and the head piece, in such a way that the right-hand long piece can be exchanged for the left-hand long piece.
One problem that is encountered when exchanging the long pieces in accordance with the above is that the hinges face the wrong way. This problem is solved in WO 00/50718 , however, by using hinges that are reversible.
Previously disclosed reversible frame assemblies nevertheless exhibit disadvantages in the form of specially designed long pieces, head pieces and sills, which designs are complicated and impede production. It can be mentioned by way of example that the sills in doors and windows that face towards the outside of a house are often executed with an inclined plane in order to improve water run-off. When utilizing such inclined sills, each long piece and/or head piece and/or sill must be specially executed in order to achieve a good fit with the inclined sill. The situation becomes especially complicated, furthermore, if the frame assembly is to allow reversibility.
There is accordingly a requirement for an improved design of reversible frame assemblies.

DESCRIPTION OF THE INVENTION

The invention proposes to solve the above-mentioned problems in a reversible frame assembly with profiled frame pieces for a hinged unit, for example a door or a window. The frame assembly is of the type which has a raised part constituting a shoulder arranged to be in contact with the hinged unit in a closed position. The frame assembly, when in the position for use, consists of a first long piece extending vertically in the Y-direction and a sill extending horizontally in the X-direction. The designation Z-direction is also used below to indicate a direction perpendicular to the X-direction and the Y-direction in an orthonormal system.
The problem of an improved design for reversible frame assemblies is solved by executing the long piece with a plane first end section, where the sill comprises an inclined top part and where a tangent to the inclined top part forms an angle α with the horizontal plane, in conjunction with which a wedge device is arranged between the plane first end section and the inclined top part. The expression 'plane' is used here to denote an extension in the X-Z plane, i.e. perpendicular to the longitudinal direction of the long piece. The inclined top part of the sill permits water, for example rainwater, to run off the sill and away from the frame assembly.
One advantage of the invention is that the plane end sections of the long piece provide a simple execution of the long piece, which permits the opportunity to manufacture a long piece simply in an appropriate length which fits different heights, e.g. in doors or windows, by cutting a standard length of long piece material to the desired length. The plane end section is also a precondition for the desired reversibility.
A further advantage of the frame assembly in accordance with the invention is that the wedge device fills the space that is formed between the inclined top part of the sill and the plane first end section of the long piece, whereby moisture and/or water in the area of the sill is/are not able to penetrate into the plane end section. This prevents rotting in the long piece. The wedge device in accordance with the invention is thus a precondition for using long pieces with plane end sections in association with a sill with an inclined top part, which prevents rotting and in addition gives an aesthetically appealing frame assembly.
The frame assembly also expediently comprises a second long piece extending in the Y-direction and opposite to the first long piece, where the second long piece is similarly executed with a plane second end section. A wedge device is also arranged in association with the second long piece between the plane second end section and the inclined top part.
The first and second long pieces are also advantageously executed with a plane third and fourth end section respectively.
In one embodiment of the invention, the frame assembly additionally comprises a head piece extending horizontally in the X-direction and executed with a shoulder. The head piece is executed so as to receive the third and fourth end sections of the long pieces, in that the shoulder at the respective short ends of the head piece is absent for a predetermined distance corresponding to the width of the respective long pieces in the X-direction. One advantage of this arrangement is that the long pieces do not need to be produced with specially executed end sections, but consist of simple, straight end sections at both ends. This facilitates production and assembly of the frame assembly.
Moreover, the plane end sections give the desired reversibility of the frame assembly in that the long piece that is applied to the right-hand side of the frame assembly is able to change places with the long piece that is applied to the left-hand side of the frame assembly. In those cases in which the hinged unit was initially hung on articulated devices on the right-hand long piece, exchange of the long pieces offers the possibility of hanging the hinged unit on the long piece which is arranged on the left-hand side of the frame assembly after the exchange and which still contains the articulated devices. A right-hung hinged unit thus becomes left-hung by the long pieces changing places.
In accordance with one embodiment of the invention, the long pieces exhibit similar or identical profiles, in conjunction with which they are capable of changing places in the frame assembly after rotation through 180° about a central axis extending horizontally in the Z-direction and after rotation through 180° about a central axis extending horizontally in the Y-direction. How the long pieces change places is of no consequence, in actual fact, for which reason the rotation described above is only to be regarded as one way of illustrating how a long piece is to be manipulated in order for a change of place to be possible.
The fact that the long pieces have a similar or identical profile is also advantageous from a production point of view, as the long pieces can be manufactured on a production line which imparts the desired profile, after which the long pieces can be cut to desired lengths without having to take account of the need for a separate profile intended, for example, for the right or the left.
The plane end sections and the common profile of the long pieces mean that it makes no difference which long piece is applied to the right side of the frame or the left side of the frame. Both long pieces are interchangeable and allow, together with the two wedge devices and the specially designed head piece, for the frame assembly to be changed from a right-hung to a left-hung arrangement, i.e. a reversible frame assembly.
In one embodiment of the invention, the sill is executed with a shoulder having an extent in the X-direction corresponding to the shoulder on the head piece, in conjunction with which all the shoulders together form an all-round shoulder on the frame assembly.
In one embodiment of the invention, the inclined top part constitutes an inclined plane surface where the tangent lies in the plane, in conjunction with which the wedge device is executed with a plane surface which corresponds to the plane surface of the inclined top part.
In another embodiment, the inclined top part constitutes a convex surface, in conjunction with which the wedge device is executed with a concave surface which corresponds to the convex surface of the inclined top part.
In yet another embodiment of the invention, the inclined top part constitutes a concave surface, in conjunction with which the wedge device is executed with a convex surface which corresponds to the concave surface of the inclined top part.
It is advantageous for the frame assembly if the top side of the wedge device is in contact with the plane end section of the long piece and if the under side of the wedge device is in contact with the inclined top part of the sill. This provides the aforementioned advantage of preventing rot. The wedge device can be manufactured with advantage from plastic, rubber or some other material that is relatively dimensionally stable and water-resistant. The wedge devices can also be manufactured from wood or some other similar material, for example when the frame assembly is to be used indoors. The wedge device can also be assembled from a number of layers of different materials. It can be mentioned by way of example that the principal structure of the wedge device is made from one material, and that the part of the wedge device that is to make contact with the end section and/or the inclined upper side of the sill can be made from another material.

PREFERRED EMBODIMENTS

illustrated in Figure 1 is a front view of an embodiment in accordance with the invention. The Figure illustrates a frame assembly 101 comprising a first long piece 1 extending vertically (Y-direction), a corresponding vertically extending second long piece 2, a head piece 3 extending horizontally (X-direction) and a sill 4 extending horizontally opposite the head piece 3. Also illustrated in Figure 1 are the wedge devices 25 which are essential for the invention.
The expression 'Z-direction' will be used below, where Z-direction denotes a direction perpendicular to the X-direction and the Y-direction in an orthonormal system.
The first long piece 1 is executed with a plane first end section 5, which faces towards the sill 4, and a plane third end section 6 facing towards the head piece 3. The second long piece 2 has a plane second end section 7, which faces towards the sill 4, and a plane fourth end section 8 facing towards the head piece 3.
The frame assembly 101 is intended to be used as frame pieces for doors, windows or similar hinged units and has a raised part constituting a shoulder 9 so arranged as to be contacted by the hinged unit. The shoulder 9 is shown in Figure 1 as an all-round shoulder 9.
The frame assembly 101 in accordance with Figure 1 is intended to support the hinged unit articulated in articulated devices 10 attached to the frame, i.e. on the first long piece 1 or the second long piece 2, in such a way that the hinged unit is capable of rotating in relation to the long piece which contains the articulated device. The articulated units 10 can consist of two hinges, for example, as illustrated in Figure 1.
As is known, a building is executed with a number of walls, which together define different spaces. Situated in the walls are openings intended to house frame assemblies intended for hinged units such as windows and doors. A number of hinged units are so arranged as to be opened in an anti-clockwise direction (right-hung), while others are so arranged as to be opened in a clockwise direction (left-hung). This is achieved by causing the articulated devices 10, on which the hinged unit is hung, to be mounted either on the right-hand long piece (right-hung) or on the left-hand long piece (left-hung).
Every long piece 1, 2 is executed with a frame part 11, which defines an outer part 12 and an inner part 13 of the respective long piece 1, 2. The outer part 12 is intended to make contact with the part surface which defines a vertical part of the opening in the wall, and the inner part 13 of the frame part 11 is intended to receive the hinged unit, i.e. the door or the window. A shoulder 14 is arranged on the inner part 13 of the long piece 1, 2 and constitutes a part projecting in a direction away from the inner part 13 of the frame part towards the opposite long piece 1, 2, i.e. in the X-direction. The shoulder 14 on the long piece exhibits an extent in the Z-direction that is less than the extent of the frame part 11 in the Z-direction, with the shoulder 14 and frame part 11 forming an angle on the inner part 13 of the long piece 1, 2 in such a way that the long piece has an L-shaped profile in a cross section of the long piece 1, 2 taken in the plane (the X-Z plane) formed by the X-direction and the Z-direction.
The first long piece 1 and the second long piece 2 are executed identically in respect of their profiles and are also executed with plane end sections 5-8 in the X-Z plane. The expression 'plane end sections' denotes end sections with an extent in the X-Z plane that is essentially perpendicular to the vertical extent of the long piece, i.e. in the Y-direction. The end sections 5-8 are thus not specially executed to fit either the head piece 3 or the sill 4, which is an advantage from the point of view of both production and storage, since only a single product needs to be manufactured and stored.
The head piece 3 is also arranged with a similar profile to the long pieces 1, 2, i.e. with a frame part 15 having an outer part 16 intended to make contact with the part surface of the wall which defines an upper part of the opening, an inner part 17 intended to receive the hinged unit, i.e. the door or the window, and a shoulder 18. The shoulder 18 of the head piece 3 is arranged on the inner part 17 of the head piece 3 and constitutes a part projecting in a direction away from the inner part 17 of the frame part towards the opposite sill 4, i.e. in the Y-direction, The shoulder 18 on the head piece 3 exhibits an extent in the Z-direction that is less than the extent of the frame part 15 in the Z-direction, with the shoulder 18 and frame part 15 forming an angle on the inner part of the head piece 3 in such a way that the head piece 3 has an L-shaped profile in a cross section of the head piece taken in the plane that is formed by the Y-direction and the Z-direction.
The head piece 3 is also executed to receive the long pieces 1, 2 in the sense that the shoulder is absent at the respective short ends 19 of the head piece 3 for a predetermined distance 20 corresponding to the width of the long piece in the X-direction. The design of the head piece 3 can be obtained, for example, by machining an L-shaped profile and by removing the shoulder by mechanical means for the predetermined distance. One variant is for the shoulder 18 to constitute a separate part of the head piece which has a smaller extent in the X-direction than the frame part 15 of the head piece. The shoulder 18 in the latter case can be applied to the frame part by gluing, screwing, nailing or some other appropriate means of joining in order to obtain the desired design of the head piece 3.
The sill 4 is also executed with an outer part 21, arranged facing towards the part surface of the wall which defines a lower part of the opening, an inner part 22 intended to receive the hinged unit, i.e. the door or the window, and a shoulder 23. The shoulder 23 on the sill 4 is arranged on a top part 24 on the inner part of the sill 4 and constitutes a part projecting in a direction away from the inner part 22 of the sill towards the opposite head piece 3, i.e. in the Y-direction. The shoulder 23 on the sill 4 has an extent in the Z-direction that is less than the total extent of the sill 4 in the Z-direction. The design of the sill 4 is more complicated than that of the other constituent parts of the frame assembly 101 and will be discussed in greater detail below.
The shoulders 14 on the first long piece 1 and the second long piece 2 together with the shoulder 18 on the head piece 3 and the shoulder 23 on the sill 4 are arranged in such a way that they together form an all-round shoulder 9 on the frame assembly 101. The different parts of the frame assembly 101 are executed so that, when they are joined together, they form a frame assembly with a uniform profile in at least those parts that are constituted by the first and the second long pieces 1, 2 and the head piece 3, in conjunction with which a unit that is hinged in the X-Y plane must be capable of making close contact with essentially the whole of the formed all-round shoulder 9 when the hinged unit is in the closed position against the frame assembly. In addition, the constituent parts of the frame assembly 101 must form an outer profile of the frame assembly 101 which is capable of fitting in a rectangular or square opening.
Illustrated in Figure 2 is an exploded view of Fig. 1, in which the long pieces 1, 2 are executed as mirror images of one another, with regard to their profile, along an imaginary centre line Y-Y in the Y-direction. The first long piece 1 thus has an essentially identical design to the second long piece 2 and can accordingly be derived from an originally common profile element that has been divided up into at least the two indicated long pieces 1, 2. The designation 'mirror images' used above is intended only to indicate that the first long piece 1 and the second long piece 2 are of identical appearance, but that they are arranged in the frame assembly 101 in such a way that they form the aforementioned mirror image, which can be achieved, for example, by assembling the first frame piece 1 upside down in relation to the second frame piece 2, or vice versa.
Fig. 3a shows a side view of Fig. 1 in the section IIIa-IIIa where the profile of the sill 4 is visible. An advantage of the present invention is that the long pieces 1, 2 are of identical design, which permits interchangeability between the first long piece 1 and the second long piece 2. However, the hinged unit is attached to one of the long pieces 1, 2 via articulated devices 10, for example a pair of hinges, which imparts to one of the long pieces (the first long piece 1 in Fig. 3a) a distinctive character which distinguishes it from the second long piece 2, which lacks such articulated devices. The second long piece 2, on the other hand, is executed with one or more locking devices 26 intended, via engagement with a corresponding locking device 26 in the hinged unit, to lock the hinged unit to the frame assembly 101 in the closed position.
Illustrated in Figure 3a is an axis of symmetry Z-Z in the Z-direction between the two articulated devices 10 on the first long piece 1. The articulated devices 10 are positioned symmetrically on the long piece 1, which permits the lower articulated device, upon rotation of the first long piece 1 through 180° about the axis of symmetry Z-Z, to change places in the vertical sense with the second articulated device. This is illustrated in Figure 3a by the distances D1 to the sill and the head piece respectively being the same size. After such a first rotation about the axis Z-Z, the first long piece 1 can replace the second long piece 2 in the frame assembly 101 after a second 180° rotation about the axis of symmetry Y-Y indicated in Figure 2. The second long piece 2 is also executed symmetrically about a corresponding axis of symmetry Z-Z in the Z-direction, with regard to the locking device 26, in conjunction with which the second long piece 2 can replace the first long piece 1 in the frame assembly 101, after a corresponding 180° rotation about the axis of symmetry Z-Z and after a 180° rotation about the axis of symmetry Y-Y indicated in Figure 2. A further advantage associated with the present invention arises in this case, where a hinged unit on the frame assembly 101 can be changed from rotating about the first long piece 1 on one side (the right-hand side in Figure 1) of the frame assembly 101 to rotating about the first long piece 1 on the other side (the left-hand side in Figure 1) of the frame assembly 101. A precondition for this to succeed, however, is that the articulated devices 10 are of a nature such that they permit such rotationally symmetrical interchangeability. Several such articulated devices are commercially available; see, for example, WO 00/50718 .
Figure 3a shows that the sill 4 is executed with an inclined top part 27, where a tangent 32 to the inclined top part forms an angle α with the horizontal plane 33. The figure shows that the tangent 32 to the inclined top part 27 coincides with the plane of the inclined top part 27. The inclined top part 27 may, however, consist of a curved surface such as a concave or convex surface. The tangent 32 to the inclined stop surface 27 is then taken at an appropriate point on the curved surface; see figures 7b and 7c.
The inclined top part of the sill 4 changes into a plane top part 28 in association with the shoulder (see 23 in Fig. 3b) of the sill 4. The shoulder 23 of the sill 4 is not visible in Figure 3a because of the fact that the shoulder 23 only extends in the X-direction between the two shoulders 14 which belong to each respective long piece 1, 2. In those cases in which the sill 4 lacks a shoulder 23, the plane top part 28 is so arranged as to seal against a drag strip arranged on the hinged unit. The sill 4 can be executed as a homogeneous unit produced by a previously disclosed method, or it may be constructed from a number of parts assembled into an appropriate design.
The wedge device 25 is also illustrated in Figure 3a arranged between the plane first end section 5 of the first long piece 1 and the inclined top part 27 of the sill 4. An advantage of the wedge device 25 is that it seals the plane end section 5 of the long piece 1 in such a way that any moisture and water standing on the sill 4 are prevented from penetrating into the long piece 1 from below, which prevents the long piece 1 from suffering damage.
Fig. 3b shows a side view of Fig. 1 in the section IIIb-IIIb, where the shoulder 23 of the sill 4 is visible.
Fig. 4 shows a frame assembly in accordance with Figure 1, where the long pieces 1, 2 have changed sides. The rotation of the long pieces 1, 2 described in conjunction with Figure 3a is not intended to be interpreted literally, but is only one way of showing how the long pieces 1, 2 must be manipulated in order to achieve the desired effect where a right-hung hinged unit is changed to a left-hung hinged unit. How the long pieces 1, 2 are rotated or moved between the different positions is of no consequence if the desired effect is achieved.
Fig. 5 shows a front view of a frame assembly in accordance with one embodiment of the invention, in which the sill 4 lacks a shoulder. The shoulder 9 in the frame assembly 101 in accordance with the present invention does not need to be all-round, therefore, and the sill 4 can be arranged in such a way that the inclined or curved top part 27 changes into the plane top part 28, in conjunction with which the hinged unit can be fitted with a drag strip on the under side of the hinged unit. As mentioned above, the drag strip can be used to provide a seal against the plane top surface 28 when the hinged unit is in the closed position.
Fig. 6a shows a side view of Fig. 5 in the section VIa-VIa, and Fig. 6b shows a side view of Fig. 5 in the section VIb-VIb. The axis of symmetry Z-Z is shown in these Figures, as in Figures 3a and 3b. It can be seen from Figures 6a and 6b that the sill 4 lacks a shoulder in comparison with Figures 3a and 3b.
Fig. 7a shows a side view of a wedge device 25 and a sill 4 in accordance with a first embodiment of the invention. As previously mentioned, the wedge device 25 is executed with an upper side 29 and an under side 30 which fit between the inclined or curved top part 27 of the sill 4 and the part of the plane end section 5, 7 of the long side 1, 2 that is situated above the top part 27 of the sill 4. Illustrated in Figure 7a is a wedge device having a plane inclined under side 30, which is thus adapted for use in conjunction with a sill 4 having a plane inclined top part 27. In the embodiment described in Fig. 7a, the tangent 32 lies in the plane of the inclined top part 27 as well as in the plane of the under side 30 of the wedge device 25. It can be seen from Figure 7a that the tangent 32 of the wedge device 25 coincides with the tangent 32 of the inclined top part 27 in conjunction with the use of the frame assembly 101. The angle α of the wedge device 25 is thus identical to the angle α of the sill 4, which gives the wedge device an optimal fit in relation to the inclined top part 27.
Fig. 7b shows a side view of a wedge device 25 and a sill 4 in accordance with a second embodiment of the invention, where the inclined top part 27 constitutes a convex surface, and where the tangent 32 is taken at an appropriate point on the curved surface 27. The under side 30 of the wedge device 25 is executed with a concave surface which corresponds to the convex surface of the curved top part 27. Figure 7b shows a tangent 32 which is taken at a point on the underside of the wedge device 25 and a tangent 32 which is taken at a point on the curved surface of the inclined top part 27. It can be seen from Figure 7b that the tangent 32 on the wedge device 25 coincides with the tangent 32 on the inclined top part 27 in conjunction with the use of the frame assembly 101. In order to describe a curved surface, a tangent must be taken at each point on the curved surface. In the present embodiment, the tangent 32 on the wedge device 25 must accordingly coincide with the tangent 32 on the inclined top part 27 at each point. The angle α of the wedge device 25 is thus identical to the angle α of the sill 4, which gives the wedge device an optimal fit in relation to the inclined top part 27.
Fig. 7c shows a side view of a wedge device 25 and a sill 4 in accordance with a third embodiment of the invention, where the inclined top part 27 constitutes a concave surface, and where the tangent 32 is taken at an appropriate point on the curved surface 27. The under side 30 of the wedge device 25 is executed with a convex surface which corresponds to the concave surface of the curved top part 27. Figure 7c shows a tangent 32 taken at a point on the underside of the wedge device 25 and a tangent 32 taken at a point on the curved surface of the inclined top part 27. It can be seen from Figure 7c that the tangent 32 on the wedge device 25 coincides with the tangent 32 on the inclined top part 27 in conjunction with the use of the frame assembly 101. In order to describe a curved surface, a tangent is taken at each point on the curved surface. In the present embodiment, the tangent 32 on the wedge device 25 must accordingly coincide with the tangent 32 on the inclined top part 27 at each point. The angle α of the wedge device 25 is thus identical to the angle a of the sill 4, which gives the wedge device 25 an optimal fit in relation to the inclined top part 27.
As previously mentioned, two wedge devices 25 are used in the frame assembly 101, i.e. one wedge device 25 applied between the plane end sections 5, 7 of each long piece 1, 2 and the inclined top part 27 of the sill 4.
Regardless of how the inclined top side 27 is executed, the wedge device 25 is arranged in such a way that the upper side 29 of the wedge device 25 is in contact with the plane end sections 5, 7 of the long piece 1, 2, and the under side 30 of the wedge device is in contact with the inclined top surface 27 of the sill 4. The wedge device 25 is thus executed with a plane upper side 29 adapted for contact with the plane end sections 5, 7 of the long pieces 1, 2.
Fig. 7d shows a top view of the wedge device in accordance with one or other of the embodiments in Figs. 7a-7c, where a hole 31 is arranged in the wedge device. The hole 31 can be used to secure the wedge device 25 to the respective long piece 1, 2 and/or to the sill 4 with screws.
The invention is not restricted to the above embodiments, but can be developed within the scope of the following Patent Claims. It can be mentioned by way of example that the wedge device can be executed with a number of holes for attachment to a sill or long piece. The wedge device can also be executed with pins adapted to engage in depressions produced in the plane end sections of the long piece and/or in depressions produced in the sill. The expression 'depressions' denotes, for example, drilled holes or similar appropriate depressions. The expression 'pins' denotes projecting devices adapted to the depressions. A frame assembly intended for hinged units that are opened by rotation outwards from a building, so-called outward-hinged units, is shown in the embodiments indicated above. Outward-hinged units are characterized in that, in conjunction with opening, they initially move in the Z-direction in a direction which coincides with the direction in which the inclined/curved plane falls. The invention is not restricted to outward-opening doors, but may also be applied to inward-opening doors, i.e. doors which pivot into the building in contrast to outward-opening doors.
