Description

DESCRIPTION

Window system

Sector

The invention relates to a window system for balcony, terrace or similar space, comprising window panes which are positioned between an upper rail and a lower rail at least partially in parallel, and which can be moved along the upper rail and the lower lane.

Background

It is not desirable on a balcony or terrace to have walls that obstruct the view, but an open balcony or terrace, on the other hand, is windy and potentially cold as well. However, the visibility, the protection against the wind and the choice of opening can be implemented by means of a window system composed of a plurality of sliding window panes. The lower edges of the window panes have strip structures that resemble a U-shaped profile that opens downward. Usually, there is a roller in the bottom part of the groove in the U-profile in the strip structure. The window system additionally includes upper and lower rails that are fixed directly or indirectly to the balcony structures or other construction structures. The usual form of the upper rail is a long structure composed of several U-shaped sections and having its section open downwards. The upper part of each window pane is placed in one of these U-shaped slots. The lower rail is like the upper rail, a straight structure comprising several U-sections and having its section open upwards. Each window pane is placed between the upper rail and the lower rail such that the upper part of the window glass is raised, in the upper U-slot of the rail, as high as the roller in the lower strip structure of the glass The window can be lowered onto a raised ridge in the U-groove of the lower rail. The fact that the lower strip structure is placed on a ridge in the lower rail allows the window panes to move in the direction of the upper and lower rails, but prevents the window panes from moving in the lateral direction.

It is possible to place sliding window panes in parallel, so they act as a protective wall on the side of a balcony or terrace that would otherwise be open. The sliding window panes are usually made of glass. A sliding window system can also be opened, if desired, which can be carried out by moving the sliding window elements aside along the upper and lower rails.

Such sliding window systems are, however, associated with problems. When the window panes are subjected to forces that attempt to elevate the windowpanes, a windowpane may be raised to such an extent that the lower strip structure is completely lifted out of place, on top of the bottom rail. Such an event, which is the opposite of the installation procedure, is possible when the coupling elements between the window panes collide with each other with adequate force when the windows are moved, struck, or when there are strong winds. The consequences of losing the support of the window glass in the lower rail can be that the window glass falls on the terrace or falls on the balcony or from the balcony. The fall itself can break the window element, break objects that are left under the window element and / or even cause serious personal injury. A window element that falls from a balcony threatens the lives of people and animals, and is destructive to the objects that lie beneath it.

Therefore, there is a need to develop the window system.

Short description

It is an object of the invention to provide an improved window system. This is achieved with the window system according to claim 1.

A further object of the invention is the structural element of claim 12.

Preferred embodiments of the invention are disclosed in the dependent claims. The preferred embodiments improve the advantages of the basic invention.

By the solution according to the invention, the window elements can not move from between the upper and lower rails and fall out of place as a result of a force directed to the window elements, independently of the direction of the force.

Description of the realizations

The following embodiments are presented by way of example. Although the description may refer to "a single", "a", or "some" realization at different points, this does not necessarily mean that each reference refers to the same embodiment or embodiments or that the characteristic only applies to one embodiment. The individual characteristics of different embodiments can also be combined to make other embodiments possible.

The disclosed window system is suitable for a door or window of any building. The disclosed window system is suitable, for example, for a space protruding from the wall of a building, in which access is through a door. Such space can be a balcony, terrace or similar space. A balcony can be defined as a space that extends outside the wall of a building, has a floor and is delimited by a railing, and a door can be opened from the building. A terrace is a similar space, but you can think that it is on the ground plane, so a separate floor is not necessarily included in a terrace.

Next, an example of a window system according to Figures 1A, 1B, 1C and 1D will be examined. The window system comprises at least one window element 121, 122, 123, 124. Often, however, there are at least two window elements 121-124. Each window element 121-124 has a translucent or opaque sheet, that is, a crystal 121b, 122b, 123b, 124b. Opaque sheet 121b-124b can act as a protection wall. A window element can let in light according to the production material. The light transmission can, if necessary, be set to the desired amount in the desired manner. The sheet may comprise agents that absorb and / or scatter optical radiation in a desired band (approximately 10 nm to 500 μm). In this way, the window pane can be resistant to ultraviolet radiation, for example. Similarly, the penetration of infrared and thermal radiation can be adjusted in the window pane. The window glass can also be colored, in which case its transmission of light at different wavelengths is not the same. When the window pane comprises dispersion particles, its color, the diffused or non-diffused permeabilization can be controlled with the size and number of particles in the desired manner.

The sheet 121b-124b can be made of glass and / or plastic. The sheet 121 b-124b may be uniform, the solid material or the sheet 121b-124b may be mesh, such as a mosquito net. The thickness of the sheet 121b-124b can be a few millimeters. The thickness of the window pane may be about 5 mm-10 mm, for example. There may or may not be a strip at the upper edge of the sheet 121 b-124b. The strip can be made of plastic and protects the upper edge of the sheet, like a glass window. The area of each sheet 121b-124b can be from about one square meter to several square meters. In the lower part of the sheet 121b-124b there can be, as a horizontal frame, a lower strip 121a, 122a, 123a, 124a, which can also be called a lower frame. The lower strip 121a-124a can be an extrusion made aluminum strip, such as a profile strip, for example. More commonly, lower strip 121a-124a can be made of another metal or plastic, for example, and can be manufactured by another method than extrusion. The examples in the figures do not show the upper horizontal strip on the window elements, it is dedr, the upper horizontal frame, but if necessary, it may or may not exist.

Each window element 121-124 is between the upper rail 130 and the lower rail 140. Between the window element and the lower rail 140 there may be a sliding block or roller structure (Figure 4, reference number 400). The rails 130, 140 can be made of metal, for example. The rails 130, 140 can be made of aluminum by extrusion, for example.

The lower rail 140 forms a long shape that is almost a multiple U profile in cross section, with the section open upwards. In a multiple U-profile, the different slots in the shape of the letter U are in parallel, which allows positioning the window elements in parallel with each other.

For the multiple U-profile, the lower rail 140 may comprise parallel raised ridges 141-144 for the lower strips 121a-124a of the window elements 121-124. The crests 141-144 are projections that resemble a wall, between which there are slots 146. The support for the window elements 121-124 takes place from below its lower strip and the movement control from the crests 141-143 comprised by the lower rail 140.

The upper rail 130, whose principle is shown in the example of Figure 2, also forms a long shape which is mainly a multiple U profile in cross section, with the section open downwards. In a multiple U-profile, the different grooves 202 of the shape of the letter U are in parallel, each U-shaped profile being formed out of parallel raised ridges 200 and the grooves 202 therebetween.

Such structures of the upper and lower rails 130, 140 allow the parallel positioning of the window elements 121-124 in relation to each other and their movement between the upper and lower rails 130, 140. Each window element 121-124 may be in different slots 202 of the upper rail 130 and on a different ridge 141-144 or in a different slot 146 of the lower rail 140. The window elements 121-124 can also be moved vertically by a distance which is the difference between the height of the window element and the distance between the upper and lower rails. This distance is large enough to allow the window elements 121-124 to be installed between the upper and lower rails 130, 140. This additionally allows to intentionally remove the window elements 121-124 and / or their uncontrolled exit from between the rails.

The window elements 121-124 can, by means of said clearance, be placed between the upper rail 130 and the lower rail 140 by pushing the upper part of the window element 121-124 into the slots 202 between the ridges 200 in the U-shaped profile. of the upper rail 130, and elevating the window element in the slot 202 of the U-profile, so high that the lower edge of the window elements 121-124 is above the lower rail 140. After this, the element 121- High window 124 can be placed above the desired edge of the lower rail 140. The depth of the slot 202 in the U-profile of the upper rail 130 is D, where D can be a few centimeters. The gap between the upper part of a window element 121-124 installed in its place and the upper part of the slot 202 in the upper rail 130 can be I, where I is smaller than the depth D, but it can be a few centimeters, maximum. The depth D is necessary because the upper and lower rails 130, 140 can not, in general, be installed vertically parallel because the structures of a building do not align. In such a case, the window structure 121-124 may be at different distances from the top of the slot 202 in the upper rail 130 at different times as it slides along the lower rail 140.

The window elements 121-124 that are installed in place can move forward and backward along the upper and lower rails 130, 140. When the objective is to protect a space protruding from a wall of a building, such as shown in Figures 1A and 1B, the window elements 121-124 move in positions adjacent to each other thereby blocking the side of the protruding space, which would otherwise be open. In such a case, for example, the line N in the normal direction of a window element surface, which runs in the middle of said window element, does not hit other window elements. As shown in Figure 1D, the window elements 121-124 can also be attached to the right of the left edge of the rails 130, 140 so that they are one behind the other, so that the line N in the normal direction 200 , drawn approximately in the middle of the surface on a window element 121-124 passes through all the window elements 121-124.

Therefore, the window system is comprised of sliding window elements 121-124, positioned from a parallel position to be extensions to each other, and being in a slightly different line between each other between the upper rail 130 and the lower rail 140. .

When the window system closes the space protruding from the wall of a building, as shown in Figures 1A, 1B and 1C, the window elements 121-124 may overlap at least partially, ie, slightly parallel at their ends vertical In the position according to figure 1, there is more overlap, ie parallelism, because all the window elements 121-124 are in parallel, that is, the window structure is in the open position, in which case the space which protrudes from one wall of the building is open.

In one embodiment, the window elements 121-124 comprise 121i, 121j, 122h, 122i, 122j, 122k, 123h, 123i, 123j, 123k, 124h, 124k connection members, by means of which the movement of the a window element to another window element when the connecting members of different window elements 121-124 meet and hold each other. A connecting member may be fixed directly or indirectly to the transverse end on the frame strip 122a, 123a on the horizontal edge of the window element, and / or on the side of the frame strip in the end section preceding the end cross section of the frame strip.

When the window elements 121-124 move along the upper and lower rails 130, 140, the window elements 121-124 can jump upwards when the members 121i, 121j, 122h, 122i, 122j, 122k, 123h , 123i, 123j, 123k, 124h, 124k of connection collide with each other and transmit force between window elements 121-124. In this case, one or more window elements 121-124 can move away from the area between the upper rail 130 and the lower rail 140, which can lead to the fall of the window element 121 124 in the case of a terrace, or the drop of window element 121-124 in the case of a balcony. In a way, the skip and scroll of the window element 121-124 are a chain on the back of events in relation to the installation of the window element 121-124 in its place. The window elements 121-124 can also be bent and raised due to the wind, which can also lead to the window element 121-124 moving away from the area between the upper rail 130 and the lower rail 140. In addition, the element 121 124 of window can escape from between the upper and lower rails 130, 140 if an object, animal or person hits the window element 121-124, or for another reason. If the window element 121-124 travels uncontrollably its trajectory between the top and lower 130, 140, is dangerous and can cause a serious accident.

The upward elevation of each window element 121-124, after its installation in place, can be restricted by a structural element 150, which can be fixed to the frame strip 121a-124a. When the structural element 150 is being fixed, the window elements 121-124 may already be in place between the upper rail 130 and the lower rail 140. Normally, at least the lower rail 140 is already in place, fixed to the structures of a building. The upper rail 130 can be fixed after fixing the lower rail 140 and after placing the window elements 121-124 in the lower rail 140. The structural element 150 can be fixed to the frame strip 121a-124a by means of a fixing method mechanical, for example. For example, for at least one of the following: a screw, rivet, quick fix mechanism, glue. Other methods of fixation can also be used.

Each structural element 150 reaches, when attached to the frame strip 121a-124a, between the ridges 141-144 of the lower rail 140. Each structural element 150 and at least said two ridges 141-144 on both sides of the structural element 150 in the lower rail 140 jointly prevents the elevation of said structural element 150 between the ridges 141-144 to maintain the window element 121-124 between the upper rail 130 and the lower rail 140. It is also conceivable that, since the upper rail 130 allows, for structural reasons of the upper rail 130, only a limited upward elevation for the window element 121-124, and the structural element 150 together with the lower rail 140 prevent the window element 121-124 from rising from the rail lower 140, although the upper rail 130 would allow, as such, the elevation of the window element 121-124 from the lower rail 140, the cooperation based on the characteristics uctural by the lower rail 140 and the structure the element 150 also extends to the upper rail 130.

Said crests 141-144 may be two crests directly adjacent to each other, between which there is a groove only. Alternatively, said crests may be further apart from one another, in which case there is at least one ridge and at least two slots between them. By preventing the elevation of the structural element 150 between any of the two crests in the lower rail 140, it is possible to prevent the window element 121-124 from leaving between the upper and lower rail 130, 140 and an accident and / or causing hurt.

In one embodiment, shown in Figure 3, the structural element 150 fixed in place is further extends within the ridges 141-144 of the lower rail 140 of what is the possible and restricted elevation of the window element 121-124 to the upper rail 130 between the upper rail 130 and the lower rail 140. A gap can be left U between the structural element 150 and the lower part of the groove 146 in the lower rail 140. The gap U can be, for example, from zero to a few millimeters. In such a case, the structural element 150 extends for the length L between the ridges 141-144. The possible and restricted elevation of the window element 121-124, on the other hand, is I. The elevation of the window element 121-124 is restricted by the depth D of the slots 202 between the ridges 200 in the rail U-profile upper 130. Therefore, the structural element 150, in cooperation with the ridges 141-144 in the lower rail 140, maintains the window element 121 124 between the upper rail 130 and the lower rail 140. The structural element 150 can be installed on both edges or only on one edge of the window element 121-124. The structural element 150 can also be installed in the window element 121-124 after the window element 121-124 is installed in place between the upper and lower rails 130, 140 at the desired installation location in an associated outer space with the construction

In one embodiment, shown by FIGS. 4 and 5, the structural element 150 comprises a first part 154, 158 of a locking structure 152, the shape of the first part 154, 158 being disposed in a second part 156, 160 of the blocking structure 152 comprised by the lower rail 140. The second part of the blocking structure 152 may have the length of the entire lower rail 140, or almost the length of the lower rail 140. The first part and the second part of the structure 152 blocking together prevent the elevation of said structural element 150 between the crests 141-144.

In one embodiment, the first part of the structural element 150 can be at least one recess 154 of the structural element, which fits in at least one other part in the ridges 141 144 of the lower rail 140. This other part can be an elevation 156. In In one embodiment, the elevation 156 may continue along the entire length of the lower rail 140. In one embodiment, there may be separate elevations 156 in the lower rail 140 more frequently than the width of the window element 121-124. In one embodiment, the elevations 156 may be on both sides of at least one ridge 141-144. In such a case, the recesses 154 of the structural element 150 of the structural element are disposed at the elevations 156 of two sides of the ridges 141-144.

In one embodiment, the first part of the blocking structure 152 can be at least one projection of structural element 158, which fits in the second part of locking structure 152 on ridge 141-144 of lower rail 140. This second part can be at least one slot 160. Slot 160 intended for structural projection 158 it can be on ridge 141-144 under structural ledge 158, or on adjacent ridge 141-144. With the blocking structure 152, the upward elevation of the window elements can be strongly restricted. The possible vertical movement of the window element can be millimeters or even less than one millimeter. In this way, the window elements can be effectively placed between the upper and lower rails, even in difficult circumstances.

In one embodiment, shown in Figure 3, the frame strip 121a, 122a, 123a, 124a located on the horizontal edge of the window element 121-124 can be a profile strip. In such a case, the structural element 150 can act as a cover portion 251-254, 251 ', 263 for the end opening of the profile strip. In this way, savings in material costs can be achieved.

In one embodiment, the structural element 150 can be of the same molded part, workpiece, or if not an integral part with the end portion 251-254, 251 ', 263 of the end opening in the strip 121a, 122a. , 123a, 124a of the frame. Here, being integral means that the structural element 150 and the roof part 251-154, 151 ', 263 can not be separated, and are not intended to be separated from one another. Therefore, the structural element 150 and the cover portion 251-154, 151 ', 263 in this embodiment constitute a structural and functional part. This makes the structure and assembly of the window system easier.

In one embodiment, shown in Figure 6A, the structural element 150 is arranged to be fixed in the cover portion 251-254, 223 of the end opening in the profile strip. The fixation can be carried out by means of one or more of the following: screw, rivet, glue. There may be a structural element 150 only at one end of the window element 121-124, or alternatively at both ends.

In one embodiment, the structural element 150 acting as the cover portion 251-254, 251 ', 263 comprises a member 121 i, 121j, 122h, 122i, 122j, 122k, 123h, 123i, 123j, 123k, 124h, 124k of connection, which in each window element 121-124 can be directed to another window element to assign the movement of the window element 121-124 in the other window element. The connecting member of window elements 121-124 more external, in particular, is usually directed only in one direction on the side of the window element (parallel to the line N in the normal direction of the window element), in other words, the more external window elements turn right or left . In such a case, the window elements in a prior art case, in which each connection member is fixed or structurally connected to the window element, need to be arranged precisely according to their skill for the installation location. By installing the structural element 150 only in the location where the window elements are first installed between the upper and lower rails 130, 140 and only then the structural elements 150, the problem of laterality of the window elements and all the elements is avoided Required window sizes can be packed and taken without a window element selection process separately.

In one embodiment, the member 121i, 121j, 122h, 122i, 122j, 122k, 123h, 123i, 123j, 123k, 124h, 124k of connection is of the same molded part, workpiece, or if not an integral element with the structural element 150.

In one embodiment, the structure is such that the window element 121 has connection members 121 i, 121j, the window element 122 has 122h, 122i, 122j, 122k connection members, the window element 123 has members 123h, 123i , 123j, 123k connection, and the window element 124 has 124h, 124k connection members.

A window element does not necessarily have to have the two or the four connection members.

In one embodiment, it is so that both ends of the lower frame strip, such as 122a and 123a, on the lower horizontal edge of a window element, such as 122, have a connecting member, i.e., there are members 122i. , 122j and 123h, 123k connection to allow bidirectional connection movement with the front or rear element, ie, it is possible to move both from the closed position or a partially open position according to figures 1A-1C to the open position according to FIG. 1D and also vice versa, that is, from the state of FIG. 1D to the state of FIGS. 1A-1C.

In one embodiment, the lower frame strip, such as 122a, 123a, has connecting members as examined in the transverse direction for both sides of the window element to establish the movement coupling to two other window elements. on different sides of the window element. Thus in the first two window elements, such as the element 122, they have connection members 122h, 122i for the different sides and also connection members 122j, 122k for the different sides, and correspondingly the element 123 has members 123h, 123i connection for the different sides and 123j, 123k connection members for the different sides.

A connecting member, such as 122j, 122k, 123h, 123i, is attached directly or indirectly to the sliding window element, such as 122, 123, to the transverse end of the frame strip 122a, 123a at the horizontal edge. The connection members are mentioned with the reference numbers 191-193 in Figure 1C, and the reference numbers 192-194 in Figure 1A. The other fixing location, ie the end of the frame strip, is shown in Figure 9, with the reference number 222 representing a connecting member.

In a preferred embodiment, the frame strip 121a, 122a, 123a, 124a at the lower horizontal edge of the sliding window element 121-124 is a profile strip, and the connecting member is in the cover portion 251-254 of the end opening of the profile strip.

The connecting members are projections extending in the transverse direction of the lower strip beyond the lower strip itself. A suitable range is, for example, approximately 5 mm wider than the lower strip.

In one embodiment, shown in Figure 6B, the structural element 150 comprises an expansion 650 for gripping and moving the window elements. The expansion 650 can be placed in the outermost window elements 121, 124 and the user can grab the expansions 650 and move the window elements 121-124 along the upper and lower rails 130, 140 to the desired locations. Expansions 650 may also be present in all window elements 121-124. The expansion 650 may be of the same molded part, workpiece, or if not an integral part with the structural element 150. In an embodiment in which the structural element 150 and the cover part 251-254, 251 ', 263 of the end opening are different parts, the part 251-254, 251 ', 263 of the end opening cover may comprise the expansion 650.

In one embodiment, shown in Figure 7, the structural element 150 can extend from a window element 121-124 to a second window element 121-124. The structural element 150 can be at least slightly of the shape of the letter L, as in the case of figure 5. In such a case, the structural element 150 associated with a window element 121-124 extends below the lower edge of a second window element 121 124 subsequently adjacent. In such a case, the structural element 150 normally extends below the frame strip 121a-124a of a second, subsequently adjacent, window element 121-124. If in such a case an attempt is made to raise the window element 121, for example, the structural element 150 will strike the lower surface in the frame strip 122a of the rear window element 122, and the lifting force will then be directed to both elements 121 and 122 of window. In such a case, the elevation of a window element 121 suddenly requires a force that can raise two window elements. However, the window elements 121-124 are so heavy that a person or a gust of wind will probably not be strong enough to raise two windows from the lower rail 140, even if a window element 121-124 is raised. To prevent the window elements 121-124 from rising, the window element 123 can, similarly, through the structural element 150 of the window element 122, be there to be added to the mass to be lifted. The mass of three window elements 121-124 is already so large that it is very unlikely that such forces will be directed to the window elements 121-124 which would be strong enough to raise the three window elements at the same time from the lower lane 140.

The elevation of the window element 124 can be avoided in the same way as in the case of the other window elements. In one embodiment, the outermost window element 124 comprises a structural element 150 extending below the lower edge of the frame strip 123a of a second adjacent adjacent window element 123a. In this case, it may also be below the structural element 150 of the window element 123. In one embodiment, the elevation of at least two adjacent window elements 121 124 is prevented by structural elements 150 which are directed towards each other and of which one extends below the other.

In one embodiment, the elevation of the outermost window element 124 can be avoided by the structural element 150 so that the structural element 150 can extend from the window element 124 to a slot 700 in the ridge 145, which is similar to the slot 160 in Figure 5. In such a case, the ridge 145 does not, however, support the window element 124 but is next to the ridge 144 that supports the window element 124.

This principle allows a situation to develop in which each window element it is coupled, through the structural element 150, to at least one other window element 121-124, which is added to the mass to be raised and consequently makes it difficult for the window elements 121-124 to rise from the lower rail 140

In one embodiment, shown in FIG. 8, a solution is presented in which an aperture 800-806 is formed through the crests 141-144 in the grooves in the ridges 141-144. Correspondingly, an aperture 808-820 has been formed in the frame strips 121a-124a or the structural elements 150 of the window elements 121-124. A projection 822 can be placed in the openings 808-820 in the frame strips 121a-124a or in the structural elements 150 of each window element, extending as deeply in the slot 824 in the ridge 141-144 as when the element 121- 124 of window is rising, the projection 822 hits the edge of the slot 824, which prevents the window element from rising further. Protrusion 822 may be placed on frame strips 121a-124a or ridge portion 150 on one side of ridge 141-144 or on both sides of ridge 141-144. The opening 800-806 in the ridge 141-144 can be used to pass the bit portion of a tool, such as a screwdriver or the like, from the edge of the lower rail 140 to the place where the projection 822 is to be fixed to the apertures 800-806 in the frame strips 121a-124a or the structural elements 150. The projection 822 may be a screw or a rivet, without being restricted thereto. In some cases, in which the projection 822 is on one side of the ridge 141-144, only, the opening is only needed on a ridge 141-144 of the edge of the lower rail 140. In such case, the aperture 800, by example, it is not necessarily necessary.

Therefore, according to the embodiment shown in Figure 8, there is a slot 824 on at least one side of the ridges 141-144 of the lower rail 140, in which the opening 800 806 is on the ridge 141-144. The structural elements 150 have openings 808-820, aligned with the holes 800-806 on the ridge. At least one ridge 822 may be fixed to at least one opening 808-820 in the structural element 150 in such a manner that it extends to the slot 824 to prevent the window element from rising from the lower rail 140.

Figure 9 shows how a connecting member, referred to by 224, is fixed by a fastening member 222 to the side surface of the lower frame strip 221a in the area of the end section, i.e. its end. In Figure 9, the connecting member 224 is fixed to the side of the lower frame strip 221a, in the end section of the lower frame strip that precedes the transverse end of the lower frame strip. A end section refers to the area at the end of the side of the lower strip, is dedr, the outermost section of 10% of the length of the lower strip. The closer to the actual transverse end of the lower strip is the connecting member, the less window elements need to remain in the partially overlapped position, particularly in the closed position according to Figures 1A-1C. The excessive overlap requires an extra horizontal reach, so to speak, of the glass and the lower strip, in other words, the length of the lower strip and the width of the glass. In one embodiment, the connecting member 224 may be at a distance of about 2 cm, for example, from the end of the lower frame strip 221a of 40-70 cm in length. The lower frame strip can have, for example, 300 to 1400 mm in width. In the example of Figure 9, the connecting member 224 may be of the same or a different part with the cover plate 223 of the end opening of the lower frame strip.

In one embodiment, the vertical ends 500, 600 of the window frame have a sealing structure (the small black balls in FIG. 1A which serve as an example), which provide a good seal. The joints at the ends also act as a shock absorber as the window elements 121-124 collide with the ends 500, 600.

In one embodiment, the connecting member, such as 122h, can be of the same molded part, workpiece, or if not an integral part with the end opening cover portion 252 on the lower frame strip of the type of profile strip, such as 122a. The connecting member 122i extending in the opposite direction is also of the same integral part in one embodiment. In such a case, the window elements 121-124 must be correctly selected already before the installation, so that the connection members will be of the correct type at the planned installation site. However, the uncontrolled elevation of the window elements 121-124 out of place can be avoided by means of the structural elements 150.

In one embodiment, a locking pin 312 passes through the lower rail 140. In such a case, the structural element 150 of FIG. 6A extending below the lower edge of the lower frame strip 221a-224a can not pass through. locking pin 312. In this way, the window elements 121-124 can be moved on the rails 130, 140 towards an edge, as shown in Figure 1C, and immobilized on the rails 130, 140 by means of the locking pin 312. In principle, by means of a plurality of locking pins 312, the window elements 121-124 can lock in any desired position.

It is obvious to a person skilled in the art that as the technology advances, the basic idea of the invention can be implemented in many different ways. The invention and its embodiments, therefore, are not restricted to the examples described above, but may vary within the scope of the claims.
