Description

The invention relates to a panel system, as can be seen from the introductory part of patent claim 1.

Background

Balcony extensions on buildings are equipped with glass covering of a known type, often called balcony glazing. Such systems can comprise an upper profile and a lower profile or a corresponding guide rail, in which the necessary guide rail parts are placed and between which the individual panes of glass are suspended. The glass panes are used as panels that delimit the room or protect it, for example against the effects of the weather, for example on balconies or terraces, or divide the room into several parts, especially in homes or office premises, where the panels form doors and walls. The profiles usually extend horizontally and are attached to parts of the building. With the help of parts in the guide profiles, individual panels can be opened and closed, normally about a vertical pivot axis, and the panels can be moved. The panels can be moved aside when they are not needed or when a larger space or area is to be used. In Fl 84645-B and 90796, some known balcony glazing is described. The panels can also extend down to the floor.

The panels are normally separate panels that can also be opened, and comprise at least one side of the panel, at its lower and upper end, a part for a guide rail, which also acts as a hinge when the panel is swung to the side. In addition, the panel comprises at least one part for the guide rail, in many cases two such parts or guide means, which are carried by the upper rail and/or the lower rail which prevents opening of the panel. When the panel is swung, it is supported only by two parts connected to the guide rails, the opening of the panel being possible only in a specific position. In this position, the parts are locked to those parts of an adjacent open panel, which engage with the guide rails, for example with locking and hinge mechanisms according to WO 03/42482 A1, or to a lock placed internally at the upper rail. The latch prevents the upper edge of the panel from moving and leaving the panel in an inclined position. In many cases, the upper rail is also provided with a guide member with a guide surface, to which the part that engages with the guide rail is carried until the lock is securely engaged. Normally, the locking requires precise positioning of the panel. The guide members are located at an opening in the upper rail, through which the part in the guide rail comes out of the rail. The guide ensures effective locking by holding the panel in the correct position for locking or release. Guide means carried by parts in the guide rail are described in EP 1 538 292 A22, DE 10333612 A1, US 5,272,839, and WO 03/042478 A1.

The opening in the rail must be kept as small as possible, so that the panel cannot be opened before it is in the swing position. For this reason, the parts of the guide rail which are placed closest to the opening edge of the panel must be positioned slightly differently from panel to panel, as described in WO

00/79088 A1, US 5,749,172 and SE 512602 C2. The parts for the guide rail can be placed in the corners of the panels, in accordance with the publications SE 509554 C2 and US 5,448,855, where the passage through the corner of the profile becomes easier and the panels do not collide with, for example, a railing or the walls of the balcony.

If the panels are nevertheless to be opened, the opening at the edges of the rail must be expanded in a corresponding way, because the part of each panel that lies in the guide rail is now placed in a different place in relation to the corresponding part on the preceding panel. As a result of this, the parts in the guide rail of the panels to be opened will first reach the opening long before the parts that act as hinges are in the position where locking is possible. Fl 115989 B (Fl 20041265 Al) describes a long opening and guide means which can support the panel when the roller which engages with the guide rail is in the long opening. The guide member can hold the roll within the rail which is arranged to support the roll and the panel. The swinging of the panel is only allowed after the piece attached to the panel has passed the guide, because in this position the panel can be locked to another panel or rail.

Guide members projecting from the guide rail interfered with the suspension of curtains and screens or the fastening members for such, so that the length had to be limited. However, a short guide member will not carry the panel long enough for the various parts of the locking mechanism to be reliably brought together. The guide must also carry the panel in the initial phase of interlocking, to prevent damage to the locking mechanism due to overloading.

US Patent 2,574,312 describes a mechanism for operating panels. The publication shows the parts and control body that support a panel when the panel is transferred or opened. The mechanism includes a locking system.

Purpose

The main purpose of the invention is to develop a usable panel system with guide means, which is easy to use and easy to assemble. The invention should make it possible to move the panel safely and to open it without special precautions.

The invention

These purposes are achieved with a panel system according to the characterizing part of patent claim 1. Further advantageous features appear from the independent patent claims.

The guide members in the parts that engage with the guide rail can be made shorter and smaller in accordance with the invention. Despite the small size, the guide means according to the invention makes it possible to carry the panel over a greater angle of rotation. The invention can also be used together with other guiding devices. The invention is suitable for different panels which must be able to be opened, regardless of the location of the part which engages with the guide rail. The location point for the different parts of the invention is standardized in relation to the hinge, which enables accurate and easy assembly.

The invention can be used for panels intended, for example, for balconies, as well as for panels that are to separate or limit different areas in buildings and extend down to the floor, also on balconies.

In the following, the invention will be illustrated in more detail through a preferred embodiment, which is shown in the drawings, where Figure 1 shows a schematic side view of a panel system in accordance with a first example of the invention, Figure 2 shows the operation of a second embodiment of the invention under the transfer of the panel,

Figure 3 shows the operation of examples 1 and 2 with a detail on a larger scale,

Figure 4 shows the function of an example after the panel has been transferred to its position for swinging, while

Figure 5 shows the function for the example in Figure 4 when the panel is opened, and

Figure 6 shows the function of the example in Figure 4, when the panel has been opened further.

Figure 1 shows a panel system in accordance with your first example of the invention, which is also, for example, a glazing of, for example, a balcony, or a wall that delimits an area. The panel system normally comprises several consecutive glass panes which are movable. The panels 1 are normally rectangular, normally placed vertically and form a closed wall or a large window when they are placed one after the other. They can be moved in the direction of the guide rails, which are usually horizontal. The panels 1 can be opened to a position that is perpendicular to the closed position in Figure 1.1 open position, the panels 1 are placed side by side close to each other and stored in this position, for example on one side of the opening in a balcony in a building, where they have first been moved along the guide rails. The upper guide rail 4 and the lower guide rail 5 are placed horizontally and an upper part 6 which engages in the upper guide rail and a lower part 7 which engages in the lower guide rail are arranged inside the respective guide rails, and at the same time serve as guide means, between which the panels 1 are fixed from the upper side and from the lower side, the panels being vertically oriented. The guide rails are normally aluminum rails, which are provided with a longitudinal groove for the guide rail parts. The panel 1 preferably consists of a pane of glass, the lower and upper edges of which are provided with edge strips 8 and 9, to which the guide rail parts are in turn attached.

One example of guide rail parts is shown in Figures 1 and 3, where principles known from WO 03/042482 Al are used. The panel 1 is here provided with the edge strip 9 which carries a hinge pin 10. The hinge pin 10 is profiled and is non-rotatable in relation to the panel 1 and a locking piece 12 is attached to the hinge pin 10. The hinge pin 10 of the guide rail part 7 allows the panel 1 and its swinging about a vertical swing axis XI from closed to open position and vice versa. The swing takes place around the hinge pin 10. The guide rail part 6 is suspended in the upper guide rail 4 and is supported by this, for example, by horizontal rollers, which are normally in pairs and which are fixed around the hinge pin 10. The rollers therefore carry the panel 1 and with the help of the rollers, the panel 1 is moved along the guide rail 4. A locking piece 13 that slides in the guide rail 4 and controls the movement and locks the various panels together, if necessary. The locking piece 13 remains in position in the guide rail 4 and the panel 1 can be swung relative to it. In this example, the locking piece 13 is locked to the hinge pin of the guide rail part of the corresponding adjacent panel. The guide rail 4 is also provided with a corresponding locking piece 12, to which the first panel 1 to be swung is locked. The rollers in the guide rail part 6 correspond to the rollers 11 of the guide rail part 7.

The structure of the guide rail part 6 in the guide rail 4 mainly corresponds to the structure of the guide rail part 7. The guide rail parts 6 and 7 are arranged on the same vertical pivot axis XI, in which the opening of the panel 1 is possible, and they are normally located near the first edge and to the corners of the panel 1. The guide rail part 6 has a locking piece 26 which is locked to the adjacent panel. The guide rail part 6 is in turn locked to a locking piece 19 arranged in a frame part 21a.

A further upper guide rail part 3, whose hinge pin 2 is attached to the frame strip 9, is in turn placed near the second edge of the panel 1, which is an edge that can be opened and opposite in relation to the first edge. The guide rail part 3 is suspended in the guide rail 4 and is carried by this, for example by means of horizontal rollers 14 attached around the hinge pin 2. The rollers 14 carry the panel 1 and with the help of the rollers 14 the panel 1 can move along the guide rail 4. While they are inside the guide rail 4, the rollers 14 are carried by the structure 15 inside the guide rail 4. The structure of the guide rail part 3 may differ from the structure of the guide rail part 6, and it is arranged inside the guide rail 4, and keeps the panel 1 closed. The purpose of the guide rail part 3 is to guide the opening edge of the panel 1 under the transfers and it is located close to the corner of the panel 1 in the example in Figure 1. A guide rail part or a simple guide pin 20 can be located at the lower edge of the panel 1, in the corner near the other edge of the panel, to prevent the panel 1 from being knocked out. In the example in Figure 1, the guide rail part or the guide pin 20 must be lifted up by the guide rail 5 before opening the panel 1. The guide rail 5 can also be placed lower than the floor surface. The aforementioned guide rail part or guide pin 20 and hinge pin 2 lie on the same vertical pivot axis X2, if the panel 1 is moved past the corners of the guide rail 5 and the guide rail part or guide pin 20 is lowered.

In order to open the panel 1, an opening 16 is arranged in the side of the guide rail 4, through which at least one guide rail part 3 can come out of the guide rail for swinging. The panel 1 to be opened has been moved to the opening position A, in which the panel is to be opened. There is a predetermined position, where the panel should be opened and where it can be opened. The opened panels are placed next to each other, as the guide rail part of each panel to be opened and which is placed in the open position is placed in a slightly different position on the guide rail 4. The larger the length of the opening 16 is chosen, the more panels are to be opened. In Figure 3, the first panel 27 to be swung is mounted in a fixed position and cannot be moved. The panel 27 is provided with similar parts as panel 1, but movable guide rail parts are not necessary, as the hinge pin of the panel 27 is attached pivotably to the frame 21a. A corresponding frame part is attached to the guide rail 5.

When the panel 1 is moved towards the opening position shown in Figure 1, 2 or 3, in which the panel 1 can be swung and opened, the guide rail part 3 is moved to the opening 16 before the first and the second of the guide rail parts 6 and 7 are in contact with, for example the locking piece 19. As mentioned in Figure 2, the guide rail part 3 is carried by the structure 15 in the guide rail 4, so that the panel 1 is not allowed to be opened or swung in an inclined position.

In the example in Figure 1, the panel 1 or the edge strip 9 is attached to it, provided with a counter element 18, which, in turn, is placed against a guide element 17 in the guide rail 4, when the guide rail part is transferred to the location of the opening 16 or simply guided into the opening 16. The counter element 18 is, for example, rectangular. Panel 1 is carried by the guide element 17 only with the help of the counter element 18. The guide element 17 comprises a counter surface which is parallel to the panel and in contact with the counter element 18. The counter element 18 has a side surface which acts as a counter surface and along which counter surface to guide element 17 slides. The length of the side surface of the counter element 18 is clearly greater than the length of the counter surface of the guide element 17, typically a multiple. The guide element 17 extends to a distance from the guide rail 4 in the direction in which the panel 1 is opened, the side surface of the guide element 17 acting as a counter surface and keeping the guide rail part 6 pressed against the locking piece 19 when the panel 1 is swung. Figure 1 shows a situation in which the counter surface of the guide element 17 and the counter surface of the counter element 18 are placed in a mutual position that allows opening of the panel 1. The counter element 18 has passed the guide element 17. The counter surface of the counter element 18 can slide against the counter surface of the guide element 17 when panel 1 is opened .

The guide element 17 can also have a function where the counter surface is allowed to tilt around a vertical axis of rotation, in which it will correspond better to the movement of the counter element 18 during the oscillation. This operation can also be arranged so that the counter element 18 is supported by the guide element 17 only during the transfer of the panel 1, when the guide rail part 3 is moved at the opening 16, but the counter element 18 is not carried by the guide element 17 during the swing. During the swing, the panel 1 will thus be supported either by another element attached to the guide rail 4, or simply by the locking. The purpose of the counter element 18 is therefore only to prevent oscillation.

The guide element 17 is held in place in the guide rail 4. The counter elements of all the panels, corresponding to the counter element 18, are placed in different places on different panels. The counter element 18 can be mounted on the edge strip 9 which has a fixing groove 28 shown in Figure 4, where the guide rail parts 3 and 6 are also fixed. The counter element 18 and the guide rail part 3 are separate parts and their position can be adjusted. Figure 2 shows another panel system whose parts mainly correspond to the example in Figure 1. In Figure 2, the opening 16 is narrow and the guide element 29 is placed in the opening 16. The guide element 29 is attached to the guide rail 4 and it includes a counter surface which can cause tilting and which is in contact with the guide rail part 3 when the panel 1 is open. The rollers 14 of the guide rail part 3 roll along the guide element 29. The guide rail part 3 enters the opening 16 in the open position. The guide element 29 extends to a distance from the guide rail 4, where the counter surface of the guide element 29 keeps the guide rail part 6 pressed against the locking piece 19 when the panel 1 is swung (see figure 3). The guide rail parts of each panel, corresponding to the guide rail part 3, are placed in different positions in the panels. In this example, the guide rail part or hinge pin 20 will exit the guide rail 5 through the opening (see Figure 3). Figures 1 and 2 also show an example of a guide element 21 attached to the guide rail 4. The guide rail 4 typically has an inverted U-shape, and the guide element 21 is attached to the underside of the wall in the guide rail 4 to which the guide element 17 or 29 is attached and which is provided with the opening 16. The guide element 21 consists of one or more openings 21d, through which the counter element 22 can be guided, as shown in Figure 5. The counter surface 22a of the counter element 22 is in contact with the counter surface 21e of the guide element 21, so that the counter surface 21e of the guide element 21 keeps the guide rail part 6 pressed against the locking piece 19, when the panel 1 is swung. The counter surfaces 22a and 21e extend mainly across the longitudinal direction of the guide rail 4. The counter element 22 is mounted in the edge strip 9 in the fastening groove 28. The counter element of each panel, which corresponds to the counter element 22, is placed in the same position on the panels and at the same distance LI from pivot axis XI. More precisely, the counter surface 22a is located at the same distance LI.

In the present example, the distances L2 and L3 of the openings 21d are equal, and they correspond to the distance between the guide rail part 6 and the corresponding guide rail part of the adjacent panel, when the panels are adjacent to each other and interlocked. As shown in Figure 3, the distance L4 between the pivot axis X3 of the panel 27 and the counter surface 21e mainly corresponds to the distance L4. In the examples shown, there are openings for three pivotable panels, where the first opening on the left side in the figure is for the panel 27 and its counter element 22 is located close to the guide rail part 6, closer than the counter element 18 in Figure 1 or closer than the guide element 29 or the guide rail part 3. Because the counter element 22 is close to the guide rail part 6, the counter element 22 can be made smaller in relation to the guide element 17, which is at a greater distance. By making the counter element 22 larger, the panel 1 can be carried further than with only the guide element 17 or 29. The panel 1 can be opened to a very large angle and remain constantly carried by the guide element 21, to enable and secure the locking. The guide element 21 can be used to improve the function of various locking mechanisms and to support the action of the guide element 17 or 29 or to replace the guide element 17 or 29 either completely or partially.

The minimum and maximum opening angles, in which the panel 1 is carried by the guide element 21, can be influenced by the design of the counter element 22 and by suitable selection of the length of the counter surface 21e. In the present example, the length of the counter surface 22a is greater than the length of the counter surface 21e shown in

Figure 5.

Figure 4 shows a system in accordance with an example of an embodiment and its function in a situation where the panel 1 is in the open position, where the locking is ready for engagement and the counter element 22 is ready for transfer over the guide element 21. The counter surface of the guide element 21 is convexly designed , so that it rests better against the guide element 21 during the swing. Figure 4 also shows the panel structure 27 attached to the guide element 21. In Figure 5, the counter element 22 is in contact with the guide element 21 and the locking has already been partially implemented. In the situation in Figure 6, the locking is engaged and prevents movement of the panel, and the counter element 22 has been detached from the guide element 21. In Figures 4 to 6, the guide rail 6 has been omitted to expose the construction of the guide element and the guide rail parts.

Figure 3 shows in more detail the guide element 21 from the examples in Figures 1 and 2, where the guide rail 4 is partially opened. The guide element 21 comprises a frame part 21a which is placed inside the guide groove 4 and set in place. The frame part 21 is also provided with a locking piece 19, in which the locking piece 26 is adapted to the guide rail part 6 and the hinge pin 25 is locked. The locking piece 19 is attached, for example with a hinge pin.

In Figure 3, the position of the frame part 21a determines the position of the panel 27 to be opened, which in turn determines the opening position of the next panel 1 to be transferred and opened. The guide element for each panel to be opened will be guided through a separate opening. The guide element 21 is provided with an extension 21b integrated with the frame part 21a and comprising at least one opening for the panel 27 and placed under the guide rail 4. During assembly, the opening 2ld in the extension part 21b is automatically placed at such a distance L4 from the frame part 21a that corresponds to the distance between the counter element to the panel 25 and the frame part 21a. More specifically, there is a distance L4 between the axis of rotation X3 and the counter surface 21e. The pivot axis XI and counter surface 21e are placed at a predetermined distance LI from each other, corresponding to the distance L4 when the panel 1 is in the open position, in which the distance between the rotation axes XI and X3 corresponds to the distance L2. At least one elongated part 21c can be located after the extension 21b, normally provided with one or more openings 21d. The elongate part 21 is attached to the guide rail 4. Between the extension 21b and the elongate part 21c, as well as between the elongate parts, there is a coupling 23 which comprises coupling surfaces and with which the elongate parts and their openings are automatically positioned during assembly, in such distances from the frame part 21a, which correspond to the distance between the counter elements corresponding to the counter element 22 and the frame part 21a. A corresponding coupling used as an adaptation part can also be placed between the frame part 21a and the extension part 21b. In the example, various parts are attached to the guide rail 4 and to each other by means of, for example, a screw in the coupling 23.

In the example in Figure 3, the counter element 22 is integrated into the hinge pin 25 of the guide rail part 6 by means of a coupling 24. The coupling 24 is placed in a fastening groove 28 in the edge strip 9, and the counter element 22 extends upwards from the edge strip 9 towards the guide groove 6 up to the opening 21d. The counter element 22 must be able to leave the guide rail 6 also when the panel 1 is moved over a corner in the guide rail 4. For this reason, the extension part 21b and the extension 21c are placed in an area between the frame part 21a and the opening 16, or between the guide element 17 and the frame part 21a. The counter element 22 does not extend so high that it can reach the wall of the guide rail 4. The counter element 22 allows swinging of the panel 1 only when the counter element 22 is in the opening 21d. By means of the coupling 24, the counter surface 22a of the counter element 22 during assembly is placed automatically at the distance LI from the guide rail part 6. The counter element 22 is pivoted around the pivot axis XI together with the panel 1. In the present example, only one counter element is required for each panel, located close to the guide rail part which is used as a hinge. Several counter elements can be attached to the guide rail part with the coupling, if the distance between the openings is constant. The panel is thus supported by at least two counter surfaces at the guide element. The counter elements can also be separate, and two counter elements can be connected by a link. Each panel can also comprise a number of counter elements, which means that the guide element in this case comprises a number of counter surfaces.

The lock type can differ from the design shown in Figure 3, but the frame part 21a can be modified so that the parts of the lock system that require precise positioning in relation to the guide rail part 6 are connected or fixed to this. If the frame part 21a does not include parts of the locking system, it is, for example, used as a stop, to stop the panel 1 in the open position. Alternatively, a form of locking is used as a stop, in which case the panel and the frame part are placed at a certain distance from each other, so that the two parts are placed in their correct positions in relation to the panel and its counter members. In this way, it is also possible to use the aforementioned connectors which keep the parts at the correct distances in relation to each other in the guide rail 4. A corresponding frame part can be placed and attached to the guide rail 5, but the use of an extension part will not be necessary.

The invention is not limited to the embodiments indicated above. The shape of the guide rail, edge strip and profiles can vary, as long as it is within the framework of the attached patent claims.
