Description

A HINGING DEVICE FOR A GLAZING SYSTEM

The invention relates to a hinging device according to the preamble of claim 1. The invention also relates to a frame part of a hinging ar- rangement for a glazing system according to the preamble of claim 15.

In the construction of new buildings and in building renovation, glazing systems of prior art are installed in connection with balconies, said glazing systems being called for example balcony glazings. The sys- terns typically comprise an upper profile and a lower profile inside which necessary guide members are placed, single glass panes being suspended between said guide members. The profiles typically extend horizontally and they are fastened to the structures of the building. By means of guide members it is possible to open and close individual glass panes, typically around a vertical axis of rotation, and they can also be transferred aside along the profiles, wherein several glass panes form a vertical stack, and the balcony is completely open.

Known balcony glazings are disclosed in patent publication FI 84645, application publication EP 1 085 153 A2, and in patent publication FI 92517 and application publication WO 92/17673. The publications also disclose shaft journals to which control wheels are attached that move inside the lower profile or the upper profile. The shaft journals are also attached to a profile or fillet to which the glass pane is mounted. The shaft journal and control wheels support the glass pane.

According to the patent publication FI 84645 the guide members comprise a hinging and locking piece for each glass pane, by means of which the glass panes that have been turned aside are interlocked. The pieces are positioned against each other and locked when the glass panes are turned and taken close to each other. Said pieces are positioned at a distance from each other when the glass panes extend straight up, wherein the glass panes form a continuous wall, and the distance of the pieces corresponds to the width of the glass panes.

Application publication EP 1 085 156 A1 discloses a known method for locking the hinging piece and the pivoted glass pane in their places, but there is, however, such a problem that the hinging piece must be fixed precisely at the location of the locking piece, said locking pieces being located only within a fixed minimum distance from each other. In the system it is not possible to lock the glass pane steplessly to any position in relation to the profile, and the use of glass panes also requires special attention because the pieces must be positioned with respect to each other to enable the locking. Furthermore, it should be noted that the tongues that function as locking devices must be positioned accurately and in a stationary manner to a predetermined position.

In the solution disclosed in the patent publication FI 84645 the glass pane does not have to be positioned in relation to the profile in connection with the locking, wherein it is sufficient that the glass panes, and at the same time the locking pieces are pressed against each other. Furthermore, the locking piece guides itself to the correct position inside the profile, wherein it is not necessary to fix the locking piece to a predetermined position, wherein it can rotate freely. The structure of the locking piece is, however, problematic in view of the torque forces, wherein bending forces are exerted thereon that are caused by the weight of the glass panes that hang on the support of a hinge pin. This restricts the selection of materials and the forces may force the locking piece for example due to deformation to a position in which the locking cannot be performed successfully or the locking piece is not capable of easily moving inside the profile.

It is an aim of the invention to eliminate the aforementioned problems by introducing a hinge pin of a new type. The hinging piece according to the invention is presented in claim 1. The frame part of a hinging arrangement for a glazing system is presented in claim 15.

By means of the invention it is possible to avoid torque forces and other force effects exerted on the locking piece that result for example from the weight of glass panes and the handling and moving of the same. By means of the invention the locking piece can be suspended from the hinge pin in such a manner that it is capable of hanging freely. The hinge pin according to the invention carries the entire weight of the glass panes, and the weight is not transmitted to the locking piece, to the locking means or through them to the guide. In connection with the locking it is not necessary to apply any more force that is necessary to turn the glass pane, and the locking does not require accurate positioning with respect to the profile. The way in which the locking piece is attached enables the use of quite different locking pieces, and their easy replacement, and it is not even necessary to install the locking pieces to the hinging piece, if locking is not necessary. The locking piece does, however, contain the necessary locking means, wherein it is especially easy to add the locking at a later stage. When the locking is added, it is not necessary to change the profile or attach additional parts.

The hinging piece according to the invention contains a set of wheels and locking means as well as fastening means for the glass panes ar- ranged in the same piece that pivots around a rotating axis in the Y direction and supports the glass panes. The locking means are intended to function together with the locking piece that is fastened to the adjacent hinging piece.

In the following, the invention will be illustrated in more detail by means of a preferred embodiment, wherein reference is at the same time made to the appended drawings, in which

Fig. 7 shows the frame part of the hinge pin according to Fig. 5, seen from the side in the Z direction, and

Fig. 8 shows the frame part of the hinge pin according to Fig. 5 in a perspective view.

According to Fig. 1 , a glazing system that has been installed in its place typically comprises several successive glass panes 1 that can be moved. Typically the glass panes 1 have a rectangular form, and they are positioned in the X and Y direction, wherein they are in an upright position, forming a closed wall when placed one after the other. They can be transferred in the X direction that is typically the horizontal di- rection. The glass panes 1 can be opened into a position in which they extend in the Y and Z direction, said position being perpendicular to the closed position. In this position the glass panes 1 can be moved aside in such a manner that they are positioned side by side close to each other, wherein they are stored on one side of an opening 3 in a building 2. The upper profile 4 and the lower profile 5 are positioned in parallel to the X direction and each one of them comprises the necessary guide members 6 and 7 to which the glass panes 1 are fastened both from above and below.

Fig. 2 shows in more detail a locking piece 8 of related art that belongs to the necessary guide members and is placed especially in the upper profile 4. The piece 8 comprises rolls 9, on the support of which the glass panes 1 of Fig. 1 hang from the upper profile, and a hinge pin 10 that constitutes the necessary hinging piece and is fastened pivotably to the piece 8 and via which the glass pane is fastened to the piece 8. The locking piece 14 shown in Fig. 3 is constructed according to the aforementioned principle. When the pieces 8 of Fig. 2 move in the X direction, the hinge pin 10 extends in parallel to the Y direction. The lateral direction, i.e. the Z direction is perpendicular both to the X direction and to the Y direction, wherein an orthogonal system of coordinates is formed at the same time.

The piece 8 contains a rear end 82 that comprises fitting means 83 for fastening the hinge pin 10, the hinge pin 10 also pivoting in said fitting means, being at the same time arranged in said guide members. The piece 8 also contains a front end 81 comprising locking means 84 for locking the hinge pin 10 in a determined rotating position. The hinge pin 10 that can be locked is fastened to a preceding similar piece. The pieces 8 are typically identical, wherein the structure and the dimensions are similar. The pieces 8 are typically also symmetrical in relation to such a plane that coincides with the X and Y directions and is lo- cated on the central line of the piece. The front end 81 and the rear end 82 comprise an upper surface and a lower surface each, said surfaces being planar in the X and Z directions.

The locking prevents the divergence of the pieces 8 in the X direction. For the locking the pieces 8 are transferred against each other, and the hinge pin 10 must be positioned in a locking gap 85. The width of the hinge pin 10 in the first rotating position A is smaller than in its predetermined second rotating position B. In the position A it has access to and away from the locking gap 85, but not in the position B. The aperture 86 of the locking gap 85 controls the access inside and outside. The glass panes typically also contain a fillet or a profile 12 to which the hinge pin 10 is fastened by means of a groove 13.

Fig. 3 shows a locking piece 14 according to a preferred embodiment that is utilized in the invention. The piece 14 also contains a rear end 142 comprising fitting means 143 for fastening the hinge pin 10 (not shown in the drawing). The means 143 comprise at least an opening 146 that extends through the rear end 142 in the vertical direction and a recess 147 surrounding the opening 146, which recess is shown in the side projection of Fig. 4 (cross-section C - C) and in the position of Fig. 3 underneath the rear end 142. The hinge pin rotates in the opening 146 and the collar in the hinge pin is positioned in the recess 147, wherein the piece 14 can at the same time hang on the support of the hinge pin, wherein it is not necessary for the piece 14 to slide along the upper profile, wherein it does not support the glass panes on the upper profile. If necessary, it is possible to arrange a separate, pref- erably replaceable plate part of plastic material underneath the piece 14, which plate part slides well when needed. The structures inside the profile control the position of the piece 14 at least in the Z direction, if necessary.

The piece 14 also contains a front end 141 comprising locking members 144 in whose locking gap 144a the hinge pin is positioned. The dimensioning of the aperture 144b of the locking gap 144a is adapted to allow the passage of the hinge pin in the position A of Fig. 2, but not in the position B. The front end 141 is positioned underneath the rear end of the preceding piece and the rear end 142 is positioned underneath the front end of the next piece. Because of the step-shaped structure of the piece 14, the front and rear ends of the other pieces are positioned on different sides of the piece 14. The locking means 144 form a bifurcate fork 144c, 144d. The locking gap 144a is posi- tioned between the branches 144c, 144d.

Figure 5 shows a hinging piece 15 according to a preferred embodiment of the invention. The hinging piece 15 is placed together with the locking piece 14 inside a profile functioning as an upper profile. The hinging piece 15 can be connected especially to a locking piece 14 according to Fig. 3, wherein they form the necessary guide members for the glazing system. The guide members are shown in Fig. 5 in a cross- section in the Y direction at the location of rotation axis 19, when positioned inside a profile 16 that is parallel to the X direction.

The hinging piece 15 comprises two wheels 17 and 18 positioned in the horizontal plane on top of each other, said wheels forming a set of wheels on the same axis of rotation and symmetry 19 in the Y direction. The glass panes that are attached to a fillet 29 rest on the support of the wheels 17, 18, which, in turn, rest on the projections 20, 21 inside the upper profile 16 by means of their conical side surface. The projections 20 and 21 extend to opposite directions and they are posi- tioned on different sides of the axis 19. Each wheel 17, 18 rests on the support of only one projection 20 or 21 , along which the wheel rolls, wherein the wheels 17, 18 are capable of rotating around the rotation axis 19, wherein the glass panes and the guide members move by rolling along the profile 16 in the X direction. There are preferably at least two wheels. The wheels 17, 18 are fastened on top of the frame part 22 of the hinge pin by means of a screw (shown with a broken line) and for that purpose the frame part 22 is equipped with a threaded recess 30 extending in the Y direction. Each wheel 17, 18 comprises a hub part 24 or 25 that is typically made of metal, and a ring part 26 or 27 that is typically made of plastic material. The hub parts 24, 25 are locked in fixed manner, but the ring part 26, 27 is allowed to rotate centrally around the axis 19 and freely around the hub part 24, 25. If necessary, intermediate rings 28 of metal must be placed between the hub parts 24, 25, wherein the height of the hub part 24, 25 is arranged to be greater than the height of the ring part 26, 27, so that the ring part would rotate freely. The hub part 24, 25 also contains at least one horizontal shoulder whose surface is directed downward, and a corresponding shoulder in the ring part 26, 27 is pressed against said horizontal shoulder. The hub parts 24 and 25, the ring parts 26 and 27, the screw 23 and the intermediate rings 28 are rotationally symmetrical in relation to the axis 19.

A corresponding hinging piece 15 is placed inside the lower profile, but it is positioned upside down, and for example wheels 17 and 18 are not typically fastened thereto, wherein it does not contain a bearing part 31 and the narrowing of the frame part 22 extends all the way to the end. Thus, also the screw 23 and the recess 30 are missing, wherein the purpose of the frame part 22 is to connect the glass panes to the lower profile and to prevent the movement in the Z direction. In the piece 15 inside the lower profile the parts 34, 35 are also higher, because the distance between the window pane and the lower profile is typically greater than in the upper profile.

The frame part is preferably placed symmetrically and centrally on the axis 19. The frame part is also shown in Fig. 8. The bearing means on top of the frame part 22 comprise a bearing part 31 that extends on a higher level than the locking piece 14, wherein the height of the piece 14 in the Y direction is smaller by the recess 147 than the height of the narrow collar i.e. the section 311 of the bearing part 31. Thus, the piece 14 is capable of rotating freely, if necessary, even if there was an inter- mediate ring 32 between the hub part 25 and the frame part 22. The hub part 25 can also be pressed directly against the frame part 22, wherein they are interlocked by means of a screw 23. The piece 14 must, however, be capable of pivoting freely, if necessary. Thus, the piece 14 can move to a suitable position inside the profile 16, under the guidance of its various projections. The bearing part 31 also comprises a wide collar, i.e. a section 312 that is placed in the recess 147 of the piece 14, wherein the piece 14 rests on the support of the upper surface of the section 312, wherein the section 312 is preferably horizontal and its upper surface is directed upward. The height of the section 312 is smaller or equally great than the height of the recess 147, wherein the second locking piece moving underneath the rear end 142 of the piece 14 does not cling to the section 312.

The frame part 22 extends downward in the Y direction and its diame- ter is preferably equal to the diameter of the section 312. The locking means formed in the frame part 22 comprise a locking part 33 that is intended to function together with the locking gap 144 of the locking piece 14 in the manner disclosed hereinabove and in connection with Fig. 2 as well. According to Fig. 6, the horizontal cross-section of the locking part 33 follows the shape of a rectangular in such a manner that the distance between the short sides is greater than the distance between the long sides. The sides are preferably located symmetrically in relation to the axis 19, and the long sides are parallel to each other and extend vertically in the Y direction.

With reference to Fig. 5, there is a bearing part 34 in the frame part 22, underneath the locking part 33, said bearing part being circular in relation to the axis 19, and a ring part 35 that is typically made of plastic is installed centrally around said bearing part as a bearing. The ring part 35 is capable of rotating freely around the rotation axis 19 and the bearing part 34, and it rests on the inner edges of the gap of the profile 16. The gap extending in the X direction is located on the lower surface of the profile 16. The diameter of the ring part 35 corresponds to the width of the gap, and thus it is possible to utilize the same to remove the clearance in the Z direction and to position the hinge pin 15 to the desired point, typically in the middle of the gap. The diameter of the ring part 35 can also be slightly larger than the width of the gap, wherein symmetrical narrowings must be made on the opposite sides of the ring part 35, the distance between the narrowings complying with the width of the gap. The diameter of the bearing part 34 is preferably slightly smaller than the greatest diameter of the locking part 33, wherein the ring part 35 rests against the shoulder between the locking part 33 and the bearing part 34. The ring part 35 also rests against the shoulder of the foot part 36, thus remaining by the gap in the profile 16. The bearing part 34 and the ring part 35 form the necessary sliding means by means of which the hinging part slides along the profile 19.

The clearance between the ring part 35 and the bearing part 34 is arranged in such a manner that when the ring part 35 is pressed at the location of the narrowing in the bearing part 34, the ring part 35 yields, and it can be lifted up past the shoulder. The narrowings are arranged on opposite sides of the bearing part 34 and symmetrically in relation to the rotation axis 19. The narrowings are parallel to the narrowings in the locking part 33. The diameter of the section 312 must also be smaller than the inner diameter of the ring part 35. The widest part of the frame part 22 is located by the section 312.

The hinge pin 15 is fastened to the fillet 29 by means of the foot part 36 that is presented in more detail also in Fig. 7, wherein the glass panes are mounted underneath the piece 15 in the Y direction. The fillet 29 contains a gap extending in the X direction, said gap being narrower than the space inside the fillet 29 in which the foot part 36 is positioned. In the upper part of the foot part 36 there is a symmetrical narrowing 361 whose horizontal cross-section follows the shape of a rectangular in such a manner that the distance between the long sides equals the width of the gap. The long sides and their surfaces are parallel to the other narrowing surfaces of the frame part 22. In the lower part of the foot part 36 there is a symmetrical widening 362 whose width is greater than the width of the gap in the fillet 29 and it complies with the width of the free inner space of the fillet 29, wherein the foot part 36 and its widening 362 support the fillet 29. The widening 362 has preferably a substantially rectangular cross-section, but it can also be partly circular. On at least one side of the widening 362 there is an extension that extends in the X direction and whose width is greater than the width of the gap in the fillet 29. The width of the extension 363 preferably complies with the width of the widening 362 and on top of the extension there is a gap 37 that is open at least upward, preferably also to the sides in the Z direction.

In the X direction of the fillet 29 the recess 37 is lined on one hand by the widening 362 and on the other hand by the end of the extension 363. It is possible to place a nut 38 in the recess 37, the outer appearance of said nut being such that its rotation in the recess 37 around the Y direction is prevented. The nut 38 is wider than the gap in the fillet 29, wherein it is possible to utilize said nut to fasten the foot part 36 and the fillet 29 together in a stationary manner, if a threaded screw 39 (shown by broken lines) is placed and tightened in the nut from above. The threaded screw 39 on one hand lifts up the nut 38 against the inner upper surface of the fillet 29, and on the other hand presses the foot part 36 against the inner lower surface of the fillet 29, wherein the hinge pin 15 and its frame part 22 are locked in their place in the X direction. The foot part 36, the nut 38 and the threaded screw 39 constitute the means intended for fastening of the glass panes, when the glass panes also comprise a fillet 29.

When the guide members are in the Y direction positioned on top of each other in the manner disclosed hereinabove, a compact structure is attained, by means of which it is possible to achieve the advantages mentioned hereinabove. The way in which the set of wheels 17, 18 is fastened and suspended compensates forces in different directions, and horizontal sliding surfaces are large, wherein the wearing effect is less significant. By means of the structure both the wheels 17, 18 and the frame part 22 are capable of easily rotating with respect to each other. The wearing of wheels changes the position of the hinge pin 15 in the vertical direction, but this can be easily taken into account by means of sufficient clearances. The structure is as short as possible both in the X direction and in the Y direction, and only vertical forces are transmitted in the frame part 22, and said forces are not transmitted to the locking piece 14.

The invention is not restricted solely to the advantageous embodiment presented above, but it may vary according to the appended claims.
