Definitions

• the present invention relates to a pivot hinge comprising a first part intended to be secured to a substantially stationary first member and a second part intended to be secured to a second member, the second hinge part being pivotable in relation to the first hinge part about a hinge axis situated outside the hinge parts.
• the invention further relates to a window comprising such a hinge.
• Hinges of this kind are known from numerous publications such as Applicant's published international application No. WO9928581 and GB1028251.
• the hinges disclosed in these documents are adapted to be mounted in windows, where a frame member corresponds to the first member and a sash member to the second member.
• These hinges consist of two hinge parts, which are attached directly to the surface of the first and second member, respectively, so that the two hinge parts face each other.
• the hinge is thus arranged between the two members, one or both of which may be provided with recesses for housing the hinge.
• Such a construction makes the mounting of the hinge straightforward and ensures a good and reliable connection between the two members. Therefore, the resources spent on developing new hinges have been concentrated on optimising the interaction between the hinge parts, whereas alternative locations of the hinge within the construction have been more or less ignored.
• a hinge comprising a connecting piece, where a first end of the connecting piece is attached to the second hinge part and a second end comprises means for securing the connecting piece to the second member, said second end being arranged at a distance from the second hinge part seen in parallel with the hinge axis.
• the main hinge body constituted by the two hinge parts may thus be arranged on the opposite side of the first member, typically a frame member, in relation to the second member, typically a sash member, the connecting piece spanning the width of the first member.
• the main hinge body which is normally made primarily from metal having a high thermal conductivity, is thus arranged on the colder side of the frame member, whereby a thermal bridge is avoided as will later be explained in more detail.
• the first member shields the hinge from external exposure and makes the hinge virtually invisible when seen form the side of the second member towards first member, i.e. from the inside of the building when using the hinge in a roof window.
• the hinge may be arranged in a recess in the first or frame member, which leads to the further advantages that the hinge is shielded from both sides and that the connecting piece need not be as long. Based on thermal consideration the recess should, however, be located as far towards the colder side of the first member as possible.
• the securing means may simply be holes for the passage of nails or screws, but other means such as punched out teeth may also be used.
• the connecting piece is made from a sheet or plate material, which is bent into shape, preferably of steel.
• the plate shape gives the connecting piece a relatively high resistance to bending and torsion but still allows it to be fitted into a window construction without causing much expansion of the overall size of the structure.
• the connecting piece may follow the surfaces of the frame member, the bending lines of the piece being substantially parallel to the length axis of the frame member.
• This configuration minimises the space needed for the connecting piece between the frame and the cladding members used to shield the window from the weather in the mounted state.
• Any material including composites may in principle be used for the connecting piece as long as it possesses sufficient strength and stiffness to carry the weight of the window and absorb the moments occurring during opening and closing of the window.
• Steel conforming to European standard DIN EN 10140 is preferred as it is also weather resistant, readily available and well-proven.
• the connecting piece may be formed as an integral part of the second hinge part by bending, folding, compression moulding or the like or may be secured thereto by means of bolted or riveted joints, by welding or even by gluing.
• the only requirement is that the hinge unit is able to take the loads and moment occurring during operation of second member e.g. a window sash.
• the shape of the connecting piece depends on the construction in which it is to be used, but for use with pivot windows it is preferred that the connecting piece and a main hinge body constituted by the first and second hinge parts forms a unit with the overall shape of an L or a U, at least a portion of the connecting piece being substantially parallel to the hinge axis.
• the main hinge body constituting one leg may then be arranged on the side of or in a recess in the first or frame member, while the connecting piece spans the frame and is secured to the sash by suitable fasteners such as screws.
• the L shaped connecting piece is attached to the upper surface of the sash member, which is substantially parallel to the hinge axis, and if the U shaped connecting piece is used, the second leg projects into the space between the first and second or frame and sash members.
• the latter embodiments will often be preferable, as the securing of the connecting piece is then hidden by the two members.
• the length of the connecting piece is immaterial as long as the main hinge body may be hidden, but as indicated above the thermal considerations may require the hinge to be located as far from the second member as possible.
• the connecting piece should therefore span a distance corresponding to at least 1/5 of the width of the first member, and preferably approximately half of the width of the first member.
• the phrase "width of the first member” is related to the overall width at the side facing the connecting piece and that the dimensions given for the distances spanned by the connecting piece are only to be considered as rough indications of size.
• a window is provided.
• Said window comprises a pair of hinges for connecting a sash and a frame, the sash and frame each comprising two side members, a top member and a bottom member, and each surrounding a substantially rectangular opening, and where the sash may be turned in relation to the frame about a hinge axis, which is parallel to the top and bottom members and situated outside the hinge parts, each of said hinges comprising a sash hinge part secured to a side sash member and a frame hinge part secured to the corresponding side frame member, said window being characterized in that the hinge is secured to the surface of the frame member facing away from the sash member or in a recess formed in an upper surface of the frame side member, where the side facing the surrounded opening is substantially unaffected by the recess, and that the sash hinge part is connected to the sash side member via a connecting piece spanning at least a part of the frame member substantially crosswise to the longitudinal direction of the frame member.
• a pivot window is provided, in which the thermal insulating properties are improved due to the fact that the connecting piece provides for a distance between the warm interior of a room of a building and the main hinge body. Due to its position nearer the colder exterior, the cold bridge effect from the hinge is substantially reduced. Furthermore, as it is possible to provide the hinge connection without having to make intrusions into the face of the frame facing the room, a visible surface which has an agreeable appearance is obtained. Simultaneously, the risk of dirt, dust and other things getting stuck in the hinge is reduced.
• Fig. 1 shows an exploded perspective view of an embodiment of a hinge according to the invention
• Fig. 2 is a partial cross-section of an embodiment of a window with a recess for receiving such a hinge
• Fig. 3 is a cross-section corresponding to the one in Fig. 2 but marked with isotherms,
• Fig. 4 shows a perspective view of another embodiment of a window with such a hinge seen from below and in the opened state
• Fig. 5 shows a perspective view of a further embodiment of a window according to the invention
• Fig. 6 shows a sectional perspective view of the window shown in Fig. 5.
• the hinge 1 in Fig. 1 comprises three primary portions, namely the first hinge part 2, the second hinge part 3 and the connecting piece 4, where the connecting piece 4 is, in the embodiment shown, secured to the sash hinge part by means of rivets.
• the second hinge part 3 is pivotable in relation to the first hinge part 2 about a hinge axis 5.
• the hinge shown is a pivot hinge intended for roof windows the hinge axis is located outside the hinge parts, viz. somewhat above the hinge parts. This position of the hinge axis ensures that the pivoting movement may be performed without parts of the first and second members of a structure coming into conflict with each other. This will be described in further detail below.
• the connecting piece 4 and the second hinge part constitute a unit having the shape of an inverted U, with a first leg 41, which in the embodiment shown is formed by the second hinge part 3, a centre 42 intended to span a surface of one of the members to be connected by means of the hinge, and a second leg 43 is intended for connection with the other of the members to be connected.
• the second leg 43 is provided with holes 44 for the passage of nails or screws and with a pair of pins 45 intended to fit into corresponding holes in the member to which it is to be secured.
• the connecting piece may in itself be U-shaped (not shown) with its first leg attached to the second hinge part 3 by means of rivets, welding or the like, or the unit may be L-shaped having no second leg, the securing means 44, 45 being provided on the centre 42, which may then be somewhat prolonged.
• the hinge is used in a window with a frame 20 constituting a first stationary member and a sash 30 constituting a second member, which is pivotable in relation to the first member.
• the sash 30 carries a glazing 7 encased by two side members, one top member and one bottom member.
• the frame consists of a wooden profile 21 and a steel profile 22, and the hinge main body 23 constituted by the first and second hinge parts 2, 3 is arranged in a recess 22a in the steel profile 22.
• the connecting piece 4 spans the width of the wooden top surface 25 and connects the second hinge part 3 to the sash 30.
• the second hinge part 3 will therefore be denoted as the sash hinge part and the first hinge part will be denoted the frame hinge part 2.
• the plate-shape of the connecting piece 4 allows the hinge to be bent into a shape corresponding to the shape of the frame 20.
• the plate-shaped connecting piece takes up only little room and the cladding 6 is therefore only insignificantly more bulky than those used with windows with prior art hinges.
• the steel profile 22 may extend over the entire length (not shown) of the frame member adding strength and rigidity to the frame member 21, or may be a local element providing only the pocket or recess needed for the hinge. Alternatively the steel profile may be left out all together, the frame member being a traditional wooden profile with a milled recess, or the frame member may consist of three or more different components, for example by supplementing the steel and wooden profiles of Fig. 2 with one of an insulating material. Composite materials and materials such as plastic or aluminium may also be used.
• the steel profile is shown as constituting approximately half the width of the top of the frame member 21 and being arranged to the far right. It is, however, to be understood that the recess for receiving the hinge may also be arranged e.g. centrally in the frame member and that in may constitute a different percentage of the total width of the frame member.
• Fig. 3 shows the same cross section described above but with isotherms 81-86 added.
• Prior art hinges are typically arranged as indicated by the broken line 87, crossing several isotherms 81-84 and thus having the effect of a thermal bridge.
• the hinge of the present invention is located further away from the warm side of the structure affecting in substance only the outmost isotherms 81,82. From a thermal point of view the hinge should consequently be located as far away from the sash as possible.
• FIG. 4 An entire window 10 is shown in Fig. 4 in an open state.
• the frame members 201,202 of this window are made of wooden profiles with milled recesses 201a, 202a for the hinges.
• the left hinge 1 is visible from this angle, but both hinges are invisible from the inside, even when the window is turned 180° during cleaning. This is not only an aesthetical advantage, it also minimizes the risk of clothing or the like getting caught in the hinge and protects the hinge from any detergents used.
• the sash and frame each comprises two side members 201,202 and 301,302, respectively, a top member 203 and 303 and a bottom member 204 and 304.
• the sash and frame each surrounds a substantially rectangular opening 205 and 305, the opening 305 being covered by the glazing 7.
• the frame constituted by the frame members 201-204 is formed as a main frame adapted to be built-into a building structure, for instance the roof structure of an inclined roof.
• the sash may be turned in relation to the frame about the hinge axis 5, which is parallel to the top and bottom members and situated outside the hinge parts.
• each of said hinges comprises a sash hinge part 3 secured to a side sash member and a frame hinge part 2 secured to the corresponding side frame member.
• the hinge is secured in a recess 201a, 202a formed in an upper surface of the frame side member 201, 202, for instance by milling.
• the side facing the surrounded opening is substantially unaffected by the recess, and, as described in the above, the sash hinge part is connected to the sash side member via a connecting piece 4 spanning at least a part 25 of the frame member substantially crosswise to the longitudinal direction of the frame member in a manner corresponding to that shown in Fig. 2.
• the hinge has been described as used with a centre hung pivot window. It is, however, to be understood that it may also be used with a window having its hinge axis elsewhere such as midway between the centre and the top, and with other structures functioning in a similar manner, without thereby departing from the scope of the claims.
• the hinge may for example be used with rescue openings, where the displacement will allow the hinges to be thermally protected from the heat of fire.
• the hinge may be utilized in windows which during normal use rotate about a hinge axis situated at the top of the window, but which pivot for cleaning. Such windows are well known per se.
• a window incorporating the displaced main hinge body is shown in Figs 5 and 6.
• Elements having the same or analogous function as the window shown in the embodiments of the above carry the same reference numerals to which 500 has been added.
• the window 510 comprises a sash 530 constituting the second member in the terms of the invention and of which the right-hand side member 532 is shown in Fig. 6.
• the sash 530 opens at the top with respect to a main frame 540 intended to be built-into a building structure, such as an inclined roof structure.
• the rotatable connection at the top is carried out by hinges, not shown.
• the window 510 is provided with an intermediate frame 520.
• the intermediate frame 520 comprises two side members, of which the right-hand side member 522 is shown in Fig. 6.
• the top and bottom members of the intermediate frame may be virtual, as is the case in the present embodiment, the opening within the members of the intermediate frame being delimited by the side members, the top member of the main frame 540 and the glazing 507.
• the side members 522 of the intermediate frame 520 follow the side members 532 of the sash 530.
• sash 530 In order to bring the sash 530 to a reversed position, i.e. turned through almost 180°, operating means (not shown) at the top of the frame releases the sash 530 from the intermediate frame 520, following which the sash 530 may be pivoted relative to an intermediate frame 520 about a hinge axis 505.
• the hinge axis is situated outside the hinge parts, viz. slightly above the hinge parts.
• the intermediate frame 520 constitutes, in this embodiment, the substantially stationary first member, as the intermediate frame 520 remains substantially stationary relative to the main frame 540 and to the sash 530 when a pivotal movement is performed on the sash 530.
• the first hinge part 502 is connected with the stationary first member, i.e. the side member 522 of the intermediate frame 520.
• the second hinge part 503, of which only a small part is visible in Fig. 6, is connected with the first hinge part 502 and with the connecting piece generally designated 504.
• the centre 504b (corresponding to the part 42 in Fig. 1) is connected with the second hinge part 502, possibly integrally, and in the other end with a second leg 504c (corresponding to the part 43 in Fig. 1).
• the second leg 504c is connected with the sash side member 532.
