Description

6791 2

The present invention relates to a window structure comprising a frame to be attached to a window opening, hinges fitted to the frame for securing the glass to the movable frame, and latches for opening and closing the glass. The invention also relates to the hinge itself for an open-tube frame structure and to a latch operating in a frame of an open-tube structure for opening or closing a glass pane, door, hatch or the like.

It is an object of the invention to provide a window structure which can simply be adapted to openings of different sizes and which can be mounted left or right handed in place. In addition, it is intended to build the entire frame from the same material. This reduces manufacturing and storage costs.

The window structure according to the invention is especially intended for use with a frameless window glass, in particular with an additional window structure according to Finnish patent 58,674. The frameless window glass is easy to wash but requires a relatively large amount of fasteners to close tightly. Such conventional latches and other fittings form protrusions that make washing and other maintenance difficult and further increase the cost of otherwise inexpensive frameless glass. In order to take full advantage of the frameless glass, it should not have any of these protruding protrusions. It is therefore a further object of the present invention to provide low-cost latches and hinges which leave the glass surface as exposed as possible and which can be installed anywhere in the window frame without special fastening means.

These objects are achieved by a window structure according to the invention, a hinge according to the invention and a latch according to the invention, the main features of which are set out in the appended claims 1, 11 and 17, respectively.

Swedish patent publication 192 534 discloses a kind of open tube structure for attaching a glass pane or the like to a frame, which tube structure rotates around the whole frame. At the same time, this tubular structure acts as a wooden structure of the glass and encloses the glass edges along the entire circumference of the glass. Thus, the glass pane of the structure of this patent is not edge-free and does not provide a solution to the problem of the present invention.

German Offenlegungsschrift No. 1,033,886 also discloses a frame structure and a frame structure in the form of an open tube, in which an outer frame structure at its open angle is fixed to a wall structure and an inner frame structure at its open angle is correspondingly connected to a glass pane. Therefore, even this structure does not leave the edges of the glass pane free and does not provide a solution to the present problem.

The invention is based on the fact that, similarly, the central part of the frame profile revolving around the window is formed by a tube of substantially circular cross-section, which lacks a certain size, axial sheath part, i.e. an open tube. Both hinges and latches are fitted to this open tube. At the same time, the tubes act as a water collector and a pressure equalizing vortex chamber if water or air penetrates inside the glass under certain conditions, for example in the event that a latch is not properly attached. The pipe is preferably formed with a longitudinal groove in which the water entering the pipe collects. Water exits the structure through holes formed in a groove or similar point in the pipe. Said groove is provided in connection with this manufacturing process of the frame profile, in the extrusion step. The groove thus appears in every part of the frame, but drainage holes can be formed afterwards in the lower part of the frame if desired.

The arc length of the jacket portion removed from the open tube is at least 90 °, preferably between about 100 ° -130 °. Because the opening is smaller than 180 °, the hinges and sal pieces operating in it remain in the pipe. This size of the opening allows the glass to open 90 °. The edges of the open tube co-operate with the latch member therein so that the notch formed in the periphery of the latch member presses against one edge of the open tube, while the opposite circumferential side of the latch member wedges into the edge portion terminating at the opposite edge of the open tube.

The frame profile further comprises a sealing groove to which a gasket suitable for glass is attached, an outer smooth part which forms the main part of the outwardly visible surface and can be treated to the appearance of the building or covered with a desired covering strip, and a frame support part which provides rigidity to the frame or an old window.

Forming a window frame from parts of a window structure according to the invention is simple. The different parts of the frame are only cut at an angle of 45 ° to the longitudinal direction and fastened to each other in the usual way. The window structure is symmetrical with respect to the horizontal axis, so the so-called manuality does not need to be considered at the manufacturing stage. The hinges and latch pieces according to the invention can also be fitted to the window frame after the frame parts have been joined together, whereby the handiness can be easily changed even when the window structure according to the invention is installed.

The frame profile is preferably made of aluminum, the excellent extrusion properties of which can be exploited in the best possible way, both technically and economically.

Both hinges and latches can be made of, for example, extruded rod-like material without any processing other than cutting, which of course knows very low manufacturing costs. The hinges are made of, for example, aluminum or plastic, the latches are most preferably made of plastic.

The hinge consists of a cylindrical part to which the glass is suitably attached. For example, the cylindrical part has a notch to which the edge of the glass is glued. Around the rod-like part of the hinge there is preferably a separate sleeve-like part made of plastic or the like, which forms a bearing surface for the rod-like part as it rotates in the open tube. The sleeve-like bearing surface can also slide against the open tube. The sleeve-like part can be removed from the top of the hinge by pushing it up and down in the open tube. This allows the window glass attached to the hinges to be removed from the open tube of the frame because the width of the open tube opening is equal to or slightly larger than the diameter of the hinge. A sleeve-like portion fitted over the hinge increases the diameter of the hinge so that the glass cannot escape from the frame. The sleeve-like portion preferably has approximately the same cross-section as the open tube, except for the groove formed in the open tube. The cylindrical hinge part can also itself act as a bearing surface 5 67912 against the inner wall of the open tube. The hinge part is then preferably made of plastic.

The corner hinges of the window glass are preferably fitted with a detachably mounted, hemispherical bearing piece on which the hinge rotates. The shape of the bearing corresponds to the corner of the frame formed by the open tubes. The bearing piece in the upper corner is inactive when using window glass, but it contributes to the safe transport of the glass. Fitting the bearing piece to each corner also allows the glass to be turned upside down if the manual nature of the window so requires.

The hinge pieces can be attached to the glass in such an amount as to provide a tight closure against the frame seal. The structure of the hinge is such that the hinges are automatically on the same axis, so that no stresses harmful to the operation of the window can arise. The hinge structure allows the glass to open 90 °, which is sufficient for window care and ventilation.

The cylindrical hinge body is preferably formed with one or two holes of crescent cross-section in its longitudinal direction. The purpose of the holes is, on the one hand, to lighten the structure and achieve material savings and, on the other hand, to provide the possibility of attaching an additional member to the hinge. For example, a tile spring can be attached to the hinge to cause the glass to self-open when the latch is released or to close the glass, respectively. The tile spring fitted to the hinge can thus replace the so-called a windbreak that keeps the two ventilation windows locked together. The tile spring can also be installed in such a way that it keeps it closed against the glass seals, in which case the glass can be used, for example, in connection with mechanical ventilation to supply replacement air so that it prevents any vacuum from escaping from the room.

The latch structure according to the invention consists of a body of plastic or other suitable material rotating inside the open tube of the frame, with a notch for glass on one side. Immediately adjacent the notch is preferably a protrusion from which the latch can be pressed. There is still a section on the perimeter of the latch, the so-called a locking notch that presses against the other edge of the open tube of the frame, whereby the latch piece forms a kind of wedge between both edges of the open tube and at the same time presses the glass edge against the seal of the frame. Pressing the latch at the opening of the open tube causes the locking step to be released, whereby the latch rotates inside the tube and the glass edge is released. The latch piece preferably has an axial hole, the cross-section of which is, for example, in the shape of a circular segment. The purpose of the hole is to lighten the structure or create a space for the member to be attached to it.

Preferably, a segment is removed from the circumference of the latch body approximately opposite the notch. The length of the latch diameter at the segment is approximately equal to or slightly less than the distance between the edges of the open tube. Thus, when the latch is in the unlocked state, it can be easily removed from the frame and fitted therein. The latch can also be removed from the open tube without said segment cutting when the glass is open and the latch at a certain angle of rotation. The latches are locked in place in the open tube, for example with latch rings or simply by bending the edges of the open tube inwards above and below the latches. The latch pieces are fitted to the frame-tube in the required number and to the required sides according to the window size, wind conditions, etc. The latch at the bottom of the window also acts as a load-bearing member in the case of a wide window.

In ventilation windows, a long latch formed of latch pieces according to the invention can be used, in which several latches are connected together to provide several locking points. The long latch consists of a suitable torsionally rigid rod,

(I

7 6791 2 into which the desired number of these latches is threaded.

One of these pieces forms a drive and locking piece. The other pieces are otherwise similar in cross-section to the locking piece, but lack the locking section described above. They keep the glass locked by means of a torsion bar.

The invention will now be described in more detail in the form of preferred embodiments and with reference to the accompanying drawings, in which Figure 1 shows a front view of a finished window structure according to the invention with a glass mounted on a frame and a suitable number of hinges and latches · Figure 2 shows a vertical section along line II-II in Figure 1 enlarged and the window structure attached to the old window; Fig. 3 shows a horizontal section along the line III-III in Fig. 1, the window structure attached to an old window; Fig. 4 shows a perspective view of a window corner according to the invention and an associated hinge, Fig. 5a shows a cross-section of a hinge according to the invention in the closed position of the glass; Fig. 5b shows the same as Fig. 5a, in the open position of the glass; Fig. 6 shows a perspective view of a hinge according to the invention with tile springs fitted to it and fixed to glass; Fig. 7a shows a cross-section of a latch body according to the invention in the locking position; Fig. 7b shows the same as Fig. 7a with the latch in the non-locking position; Fig. 8a shows a long latch assembled from latch pieces according to the invention with locking latch rings, and Fig. 8b shows a latch piece according to the invention with latch rings.

Figure 2 shows a vertical section of the window structure, which shows the structure of the frame profile 1 and the installation of glass in it.

The frame is installed in the frame of the old exterior window and forms an additional window structure that protects old frame and frame parts and provides heat and sound insulation. The essential parts of the frame profile are the glass receiving open tube part 4, the sealing groove 5 to which the glass seal 6 is fitted, the outer smooth part 7, which forms an outwardly visible surface and can be painted in a suitable color or covered with a suitable cover strip, and the frame support part 8. to the window structure below. The support part 8 has a groove for the seal 9 against the underlying structure. The support part 8 forms a rigid part of the profile and gives the frame structure the necessary strength and rigidity. The length of the open arc of the open tube part 4 is about 100 ° -120 °. The hinges and latches fitted to the open tube certainly remain inside the tube, since their outer diameter is the same as the inner diameter of the open tube. The groove 10 formed in the open tube 4 is clearly shown in the figure, and the lower frame part also has holes 11 for draining water. A groove 10 is arranged between the outer smooth part 7 and the support part 8, whereby water can be suitably discharged along the wall of the support part 8. The open tube structure of the frame profiles gives a certain adjustment margin with respect to the size of the glass. Hinges and latches fitted to open tubes limit this adjustment space somewhat, as they require a certain length of glass edge to be sure to work. The location of the opening of the open tube 4 in the frame profile 1 is arranged as far as possible towards the light opening, whereby the profile covers the light opening as little as possible. Figure 2 shows an approximately optimal solution in this respect.

Figure 3 shows the same window structure as in Figure 2 in horizontal section. The section is made along the line ΙΙΙ-ΙΪΙ in Fig. 1 through the latch body 2 and the hinge 3. The latch body 2 appears as a substantially circular body fitted to the open tube 4. The outer diameter of the latch piece 2 and the inner diameter of the open tube 4 are the same size and the cross-sectional surfaces substantially correspond to each other. A small wedge-shaped body of the locking section 11 has been removed from the circumference of the latch piece

II

5,67912. When the latch is turned counterclockwise, in the embodiment of the figure, the inner edge of the open tube is pressed against the locking step 12 in the locking position. At the same time, the latch moves to a slightly eccentric position relative to the open tube, whereby the latch wedges between the inner edge 12 of the open tube and the inner surface of the circumference terminating at the outer edge 13. The latch has a circumferential notch 14 for a lockable edge of the glass. Notch 14 allows a small tolerance for the size of the glass. The circumference of the latch piece has a protrusion 15 inside the notch from which the latch is rotated to the locking position. The latch is released by pressing the latch between the locking step 11 and the projection 15. In this case, the locking step is pressed inside the edge 12 and the latch piece moves back to the central position relative to the open tube, whereby the wedge effect is eliminated and the latch can rotate clockwise, releasing the glass edge. The locking position of the latch is shown in Figure 7a and the releasing position in Figure 7b. In the same figures, an alternative circumferential shape of the latch body is drawn in broken lines 16 with the segmental body removed. This shape facilitates the removal of the latch from the open tube by turning the latch counterclockwise without the glass getting between the latch and the profile, with the narrower diameter at that segment facilitating the removal of the latch between the edges 12 and 13 of the open tube. Latch pieces of this shape can very simply be added to and removed from the window structure when the window is open.

The latch piece preferably has a longitudinal opening 17, which is shown in Figures 3, 7 and 8 in the shape of a semicircle. The opening 17 can be used to form a long latch. Such is shown in Fig. 8a and in the embodiment shown consists of three latch pieces through which a torsionally rigid rod 18 is threaded. The long latch provides several locking points, all of which are operated by only one latch. In the long latch according to Fig. 8a, the middle latch is provided with a locking step 11 and the latch is locked 10 6791 2 and opened by turning and pushing in this latch. The latch pieces at the end of the latch rotate with the rod 18 and provide the same locking effect as the middle latch.

The separate latch pieces or the long latch, respectively, are fixed in place in the open tube, for example by means of latch rings 19, which are shown in Figures 8a and 8b. Alternatively, the latches can be secured in place simply by cutting the edges 12 and 13 of the open tube above and below the latches to form barrier pieces in the open tube.

Figures 3, 4, 5a, 5b and 6 show the structure of the hinge according to the invention and its operation. The embodiment according to Figure 4 consists of a cylindrical hinge piece with a notch 21 for fixing glass. A sleeve-like bearing surface 22 is threaded on the hinge body 3, the outer diameter of which corresponds to the inner diameter of the open tube and the inner diameter of the hinge body. The bearing surface 22 is preferably a plastic or other slippery material. The hinge entering the lower corner of the window is removably attached to a hemispherical bearing piece 23, which in the corner of the window forms a delicately movable hinge bearing. The bearing piece 23 is preferably made of hard plastic or the like. Parallel holes 24 are formed in the hinge body in parallel with the notch 21. The holes 24 mean saving material and at the same time offer the possibility of attaching additional members to the hinge. Figure 6 shows the attachment of the plate spring 25 to the hole 24 and the frame. The tile spring thus arranged causes the window to open by itself when the latch has released it from the lock. The glass fixing notch 21 is preferably formed slightly eccentrically in the hinge body, i.e. slightly outwards from the center with respect to the embracing position of the glass. This results in the placement of the glass closer to the outer edge of the structure and to the optimal so-called measures the light shaft. The diameters of the hinge piece 3 and the bearing surface 22 are adjusted so that the hinge 11 6791 2 with its bearing surfaces does not fit out of the open tube, whereas instead the hinge from which the bearing surface has been pushed out can fit in that opening. The inner surface of the bearing surface 22 can also act as a primary bearing surface, whereby the hinge piece 3 slides against said inner surface. In this case, the bearing surface 22 has approximately the same cross-sectional shape as the open tube.

The hinge according to the invention also works well without a removable bearing surface. In this case, the hinge body must be coated or covered or it may be formed entirely of a suitable slippery material. In this case, the glass with its hinges 3 must fit the frame profile to the open tube 4 before closing the frame at the corner points.

It is clear from the foregoing description that the latches and hinges according to the invention can also be used in connection with other structures, such as doors, hatches, covers, etc., as long as the structure in question is fitted to a frame in an open-tube structure.
