Description

The invention relates to a system of fittings and its use for retractable sliding casements of windows, doors or the like. In this case, as the supporting elements for the sash, for example, two upper and two lower outlet arms are used, which are pivotally mounted on the side of the sash without the possibility of movement, on the contrary, their other ends are supported with the possibility of rotation on the upper guide rail located on a separate frame and the lower running bar by means of appropriately guided upper running elements and, accordingly, lower running carriages.

In the case of the known sliding flaps and their fittings system, there is the disadvantage that the axes of receiving loads are located at a great distance from the respective separate frames. Also, the covering elements for the parts of the system of fittings should accordingly extend far into the interior. The disadvantage is that special designs are necessary for the profiles of the sash frame, which generally increases the cost of the sliding sashes if a large batch volume cannot be achieved. Specific profiles can, of course, be developed for special solutions and the special geometry of the valves, but the latter in this case depend on the specific special solution, as disclosed, for example, in document EP 06100345.5 (Schüco / Hatau, now EP-A 1688573), where, in particular, a pair of brackets located on top and a pair of brackets located on the bottom with the formation of C-shaped fittings are interconnected using a vertical rod (key 20 in figure 1), however, for basing between the movable sash and the fixed sash, Dima special form and execution profiles and overlap, to make such a structure capable of embedding and allow at the same time hidden work.

Accessories in an open manner with an upper and lower pair of brackets are shown in document EP-A 916794 (VKR Holding, Velux), in which the brackets located on the edge side, at least when the sash is closed, are located in the visible area and impair visual perception, compare Fig. 12 of this document.

US-F 4384429 (Rockiki, Inline Limited) shows a sash which does not extend from a separate frame and does not enter it, but which, however, can certainly move in the direction of the surface and contains two vertical connecting rods equipped with upper and lower brackets. The movement remains, meanwhile, the same as the lateral movement on the brackets inside the outer borders of the separate frame, which is suitably reinforced. The sealing surfaces are not optimal, nor is it possible to overlap the flaps to improve visual masking on the flap profile. Moreover, the lower brackets in the closed position remain visible from the interior of the room, and the upper exposed brackets are also visible when approaching them. Both vertical connecting rods are held from above on the gears by means of gear elements and a connecting rod as applied to the synchronous movement when performing lateral movements of the leaf, compare column 5, lines 45-47 of this document.

The objective of the invention is such a further improvement of the system of fittings of the named type, which makes it possible to use conventional frame profiles (the so-called hollow profiles), which are known for pivoting sashes, pivoting-folding sashes or folding-sliding windows, and ensuring their suitability at least in Germany e.g. plastic or metal profiles. These profiles are inexpensive and provide a high degree of compaction in the closed position. Due to the new system of fittings, this high degree of compaction should not deteriorate or the deterioration should be only very slight. The next goal of the system is to position the load-receiving parts of the system of fittings as densely as possible to fill the sash in order to keep the emerging torques and torsional forces as low as possible. The filling is, for example, a sheet of glass in the frame of the sash, which may have a substantial mass. The hardware system must be designed so that it can be integrated or used in this way.

This problem is solved by the solution described in paragraph 1, in which the vertical rod element connecting the upper and lower outlet arms for performing synchronous movements can be located in the hollow space of the usual hollow profile of the sash frame and, thus, can be close to the filling of the sash. We are not talking about a special profile form specially designed in the marginal region, but such a form, which provides, first of all, equipping with hollow enclosed spaces, in particular, in the overlapping area.

The problem is also solved using clause 2 or clause 20. The system of fittings is made in such a way that the most important elements, in particular the load-receiving elements of the sash, can be located in the overlap of the sash or aligned (installed in one line) in the vertical direction with overlap. This happens vertically below it, in the space defined by the alignment. This space is not surrounded by overlapping, however, it is “limited”, in the sense defined or defined, in the closed position by him and his alignment directed vertically downward.

In the closed position, none of the supporting positions of the fittings is located in front of the formed (lateral) outer surface of the overlap of the wings (level 10). Thus, in the mounted state of the sash, not one load-bearing supporting element of the hardware protrudes in the direction of the inner side of the space. Only the intermediate sections of the lower outlet arms leave the space defined by vertical alignment for the overlapped wings. They are closed by a casing (item 11).

Regarding the load, the specified hardware is declared in such a way that describes its interaction with the sash and its overlap and installation on a separate frame, in order to achieve functional clarity; at the same time, hardware is declared as such with its properties and use (p. 17). Alternatively, the fittings are declared together with the sliding sash (p. 16), each independently of each other.

It also describes the possible use of accessories according to claim 1 or 2 for embedding or for the casement frames of a hollow profile with the casement overlapping, and the casement overlapping during regular use remains outside the separate frame (item 18).

Since, irrespective of the previously described clauses in clause 20, a hardware system is also declared, this should be understood in such a way that all dependent clauses 3-15 without reference to clauses 1 or 2 in this case are considered disclosed with reference to clause 20. The preferred embodiments described in these dependent paragraphs with respect to claim 1 or 2 are also preferred embodiments of claim 20 without reference to claim 1 or 2.

In conclusion, in the claims, it is possible to familiarize oneself with the operating method or the operating method (paragraphs 18, 19), and the operating method can be both a method of operating accessories according to claim 1, and a method of operating accessories according to claim 2, in this case, however, together with the corresponding peripheral elements, for example casement frames with overlapping leaves, with suitability for interaction with separate frames.

In the description of claim 1, the system of fittings is designed so that the outlet brackets, in this case the lower and upper outlet brackets located vertically one below the other, are pivotally connected to the running carriage (lower bracket) and to the running element (upper bracket) in such a way that connecting the brackets, the rod element in the form of a vertical rod is made with the possibility of hiding in the mounted state in the hollow space of the sash frame, in particular the overlap of the sash of this sash frame. As an alternative, paragraph 2 describes the load-bearing support elements of the hardware. Such a support element can be placed in a vertical hollow chamber. For this purpose, the vertical hollow chamber can be opened in a certain area in the direction of the fold space (item 9). The leaf load (its mass) is transmitted through the hinge pin, which is described in the form of a support or hinge pin, in short, a “bearing finger”, to the outlet bracket. A vertical rod element is provided on one line (in the extension of the hinge pin), which is made at least partially, preferably completely located in the vertical hollow chamber of the sash overlap.

Alternatively, the support or hinge fingers can also be rigidly mounted in the outlet arms, in this case, however, in the closed position of the fittings, in the vertical alignment below the overlap of the wings (item 20).

The next load-sensing sash element is located at a distance from the first load-sensing element, and is also made and positioned to allow entry into the hollow chamber of the sash overlap, which is equipped with a corresponding recess. This hollow chamber is a horizontal hollow chamber, which is located at a distance from both corners of the sash.

The synchronous movement of the outlet arms is provided with a vertical rod, which is provided only as a separate vertical rod (p. 14). Two horizontal connecting rods cooperate with this vertical rod, which connect the running elements directed from above and the running carriages directed from below. If, in this closed position, the supporting or deflecting finger of the system of fittings extends approximately coaxially to the horizontal bar that connects the two carriages, when the two parallel lowerogram arms and the sash surface are arranged by combining the lower horizontal bar element and the leaf surface is formed, a parallelogram is formed to ensure stability sash directions. This lying parallelogram is also provided parallel offset for the upper running elements and the upper horizontal connecting rod. The double parallel direction achieved in this way for the lower lying parallelogram and the upper horizontal lying parallelogram in combination with only one vertical bar between both front, running carriages located one above the other provides reliable synchronous movement in which there are two geometric axes, one for both front and one for both rear running carriages, however, only one of these axes is structurally connected to the vertical bar.

Below the invention is explained in more detail on the basis of schematic drawings using several examples of execution.

Figure 3 shows in cross section a "normal" profile for a pivoting, tilting, tilting or tilting-sliding window, a separate frame and sash frame, which can be used for the hardware system in accordance with examples of the invention. The profiles are hollow with a protrusion 20 of the leaf in relation to the profile of the leaf.

Figure 4 shows a cross-section through the lower horizontal crossbars of a separate frame and sash frame with parts of a mounted hardware system.

Figure 5 shows a cross-section through the front vertical crossbars of both frames from a hollow profile with integrated fittings, in particular a vertical rod 12.

Figure 6 shows in perspective a "front lower corner" of the sash frame with an integrated hardware element. The front area is located where the opening of the hole in a separate frame occurs.

In Fig.7 shows in a similar representation as in Fig.6, the "lower back corner" of the sash frame.

Fig. 8 shows a cross-section through both frames of a hollow profile in the region of the lower horizontal crossbeam and with the retractable sash closed with a casing 16 for visible fittings.

1 and 1a show a typical retractable sliding window or door sash and the corresponding (new) hardware system according to FIGS. 2 and 2a. The leaf 1 is in its offset position, set aside in the direction of arrow 8, but not yet in the direction of arrow 9. The corresponding separate frame 4 (or door frame) contains two areas: on the one hand, hole 3a, and on the other hand, closed area 3 , in front of which the sash 1 with vertical crossbars 1a, 1b can move. A guide bar 5 is located on the upper crossbar of the separate frame, and a running bar 6 is located on the lower crossbar. Both of them pass through almost both areas 3a, 3.

A parallel retractable leaf 1 is guided by two outlet arms 7a and 7b and held by two lower outlet arms 14a and 14b. The ends of both brackets located on the side of the separate frame are pivotally mounted, each on a sliding element 19a or 19b, which can move along the guide bar 5, for example, to slide, when the sash is pushed to the side. Both sliding elements are interconnected by means of the rod element 11 in one node of movement. Each end of each lower retractable bracket located on the side of the separate frame is pivotally mounted on the carriage 13a or 13b, which are guided by the rollers along the lower chassis 6, and are also rigidly interconnected using a horizontal rod element 15. Also in this case, is formed traffic knot.

The ends 7 and 14 located on the sash side (for 7a, 7b and 14a, 14b) are pivotally mounted on the sash frame. 2 and 2a, these pivot points are indicated by symbols 10a, 10b for the upper brackets and symbols 21a, 21b for the lower brackets.

The front side of the sash directed in the closing direction of the sash is designated as “front side” 1a ′, and the opposite end side is indicated as “rear side” 1b '. It can be seen from FIG. 2 that in the area of the front side, the hinge mounting point 10b of the upper outlet bracket and the hinging point 21b of the lower outlet bracket located on the side of the sash are rigidly interconnected by means of a vertical rod member 12 without the possibility of rotation. Due to this, the sash when withdrawing or pressing the handle 2 can parallelly and evenly out of its fold (region of the fold or hole 3A) and re-introduced. In this case, it leaves in the transverse direction 8 the outer borders of the separate frame 4.

As mentioned above, the system of fittings must be designed in such a way that it can be mounted on / in sash profiles, which are usual for pivoting, tilt-and-tilt or tilt-and-slide windows, that is, do not constitute a special implementation, without special costs. Such a hollow profile is shown in cross section in FIGS. 3 or 5. Symbol 4 denotes the hollow profile of the split frame, and symbol 17 denotes the hollow profile of the sash frame, the front vertical crossbeam 1a and the rear vertical crossbeam 1b of which determine by their interval the width of the sash between the front side 1a 'and backside 1b'.

Sealing elements for sealing and thermal insulation between the separate frame and the sash frame are designated WD, for example, the central seal and the outer seal. Such hollow profiles are characterized by high compaction ability.

In the hollow profiles, closed chambers 32 and 20h are made of metal or plastic, in particular the overlap region 20 (in the sash overlap itself). A chamber 32 is provided in the horizontal direction as a hollow chamber, and a chamber 20h is provided as a hollow chamber. In general, they are located in a circular manner, as well as the groove 50 of the fittings on the casement, which is parallel and at a distance from the hollow chambers, and also runs on the vertical bars 1a, 1b perpendicular to them, compare Figs. 6 and 7 and those commonly used before the priority date hollow profiles of the named type for pivoting, pivoting, tilt-and-slide flaps.

Arrow 8 indicates the direction of sash retraction into the interior. Here is located the "inner side" 20a (actually, the outer side) of the sash overlap, and the "inner side" 4a of the separate frame 4 is directed here. This refers to the space that is limited by the window or door in the outer direction, and not to the "inner space" of the separate frame 4 or sash frame 17.

This profile is also indicated in the following figures, on the basis of which the installation position of the parts of the hardware system after its installation is shown and described. Flat insert 18 is in most cases a glass sheet (sash filler).

The cross section through the lower crossbars of the sash frame and the split frame according to Fig. 4 shows the sash 1 in its closed position. The symbol 20 denotes the overlap of the sash, which is also shown in figures 1, 5 and 6.

On the lower running bar 6 there is a running carriage 13b with its running rollers. The symbol 12a designates a portion of the vertical rod element as a supporting or pivot pin 12a. The vertical rod element 12 interconnects without the possibility of turning in the front crossbeam of the retractable sash frame 17 upper and lower hinge pins 12a, 12a 'of the outlet arms 7b and 14b located on the side of the sash. The rod 12, which extends vertically coaxially to the portion 12a, is connected by means of couplings 12b, 12b 'to the pins 12a, 12a'. The most significant thing that can be extracted from figure 4, is that the system of fittings is made in such a way (outlet arms and swivel on the links of movement) that its elements after installation in the vertical zone X - in relation to the depicted closing position of the sash - are located between the inner side 4a of the separate frame 4 and the inner side 20a of the sash overlap 20, namely, as will be shown, partially in the hollow spaces 20h and 32 of the sash profile and partially in the space blocked by the sash overlap, positioned vertically in a straight line below the bottom side 20b.

Not a single element of the hardware system is mounted externally on the inner surface 4a of the sash frame 17. All elements can be mounted with a small horizontal distance from the filling 18 of the sash, as a result of which all the resulting torques and torsional forces remain limited.

In front of the thus defined space, only the sections of the outlet brackets 14a, 14b are located, however, the joints of the hinged joint for the sash or on the carriage that do not perceive and give load. This is clearly seen from the cross section of the vertical crossbar of the sash frame in accordance with Fig.5. One can see the position of the common (geometric) axis 12 'of the retracting elements of the upper and lower outlet arms and the connecting rod element 12, which are all located in the vertically extending hollow space 20h of the sash overlap 20. The lower outlet arm 14b, which is located in the area shown in FIG. 5 in front of the specified “space under the sash overlap”, also contains a bevel 14b ′, also shown in FIG. 2, from the end side, which leads to the hinge and support pin 12a and contains a load-bearing hinge place connections for the sash.

The following support elements 30, 40 on the front side (crossbeam 1a) and closer to the rear side (crossbeam 1b) of the lower crossbar of the sash are made in the form of a corner, as shown in Figs. 7 and 6, pos.31 or 40. This allows you to place them in the receiving groove 50 of the fittings both at the top 31 'and at the bottom with section 31, as shown on the right in FIG. 2 in the region of the front crossbar 1a. The hole 33 inside the support portion 30 for receiving support or pivot pins 12a fits snugly in accordance with the geometry of the profile into the hollow leaf chamber 20h, compare FIG. 5. The hollow chamber 20h also receives a vertical rod element 12. The hole 33 ends at the top at position 34, the axis 12 ′ passes through it, as described above, compare also FIG. 4.

To this end, the hollow space is partially cut, as shown. The angular shape of the support elements provides a very stable connection with the sash profile and, thus, also a good load reception, primarily due to the support and hinge pins of the hinge points 21a, 21b, which are included inside the sash profile, preferably made of polyvinyl chloride. The possibility of simple installation is provided. When using plastic or metal profiles, an open hollow chamber may already be present; the overlap of the sash when viewed in cross section has the shape of a transverse V. In this case, the vertical rod is at least partially located in the hollow chamber.

The support part 40 can also be mounted in the receiving groove 50 of the fittings on the leaf, while the support 41 itself is located in the hollow space 32 of the overlap 20 of the leaf, which for this purpose is also equipped with a notch, in this case including an inside profile reinforcement. The second supporting structural element is provided in figure 2 at the rear outlet arms from below and above and is indicated by the symbols 40 and 40 '. Each of these supporting structural elements, due to the angular shape, also contains a fastening section corresponding to the fitment groove 50, which is shown in more detail in Fig. 2 (without the casement) and, on the contrary, is shown in Fig. 7 in a mounted state for the lower running structural element 40.

The change of plane is carried out by all corner elements 30, 40 both above and below.

Also with reference to FIG. 2, it should be noted that the finger portion 12a of FIG. 4 is a lower portion extending along a straight axis 12 ′, which is generally taken along the length of the rod 12 connected by the upper and lower clutch 12b, 12b ′ . In this case, a torsion-resistant connection is provided, for example, due to at least partial flattening of the rod 12. One or another sleeve, on top of the sleeve 12b 'and below the sleeve 12b, is mounted on the cylindrical sections 12a (bottom) and 12a' (top) of the fingers and thereby forms a through axis with separate wave sections that are interconnected with torsional strength to transmit torques.

On the supporting finger 12a, there is also a section 30, not shown in more detail in FIG. 4, with an opening 33. This also applies to the support bracket 7b from above with mirror-shaped supporting elements 31 'and its supporting section 30. Both supporting sections 30, 30' receive supporting or deflecting fingers 12a, 12a '.

The geometrical closure of the rigid connection for transmitting torques in the axis 12 'can, in addition, be supplemented by a force closure, for example, using a locking device screwed into the side.

The cylindrical bushings (couplings) can also be directly replaced by sections 30, 30 'of the angle-shaped fasteners 31 (bottom) or 31' (top). In this case, the corresponding section 30 and 30 ', as shown in Fig.6, forms a connecting element 12b (bottom) or 12b' (top) of the coupling, which is mounted on the corresponding "carrier finger" 12A or 12a '(in the sense of a supporting or deflecting finger )

The implementation of this cylindrically shaped support portion 30 in one piece with the installation angle 31 transfers the installation of this corner element into the region of the sash groove 50 (groove for fitting fittings) while installing the protruding portion 30 of the support member 31 in the hollow space 20h in the sash overlap. The latter is carried out, in particular, also only partially, with a protrusion in the direction of the fold space (in the closed position). The same applies to the vertical boom element.

In general, the hollow chamber can also be a circumferential one, consisting of a vertical portion 20h in the vertical portion of the sash overlap 20 and horizontal portions 32 in the horizontal sections of the sash overlap 20. Thus, the “hollow chamber” should be understood either as consisting of sections or as a whole to determine the C-shaped concept of the rods 12, 11, 15.

In the case of the new system of fittings, a fastening for the rear lower outlet bracket 14a is also provided inside the lower horizontal crossbeam of the sash, namely, not at the rear lower end of the sash, but at a considerable distance from it, as can be seen from Fig. 7. This distance is greater than the width of the vertical bar.

In the case of the new system of fittings in the mounted state, only the lower running bar 6 is shown with the carriages 13a, 13b moving along it, the horizontal bar elements 15 connecting them and the protruding regions of the lower outlet arms 14a and 14b. They are easily closed by a low-height casing 16 in accordance with Fig. 8, so that practically none of the elements of the hardware system are visible.

In order to maintain a low structural height, the rod element 15 is located on the lower region of the carriage, whereby the ends of the outlet arms 14a, 14b can enter the structural space between the lower side 20b of the sash overlap 20 and the rod element 15 at the junction, compare FIG. 5 with front bevel 14b '.

Due to the insignificant distance between the axes of the supports and the attachment points relative to the filling of the leaf 18, for example in the groove for the fittings or hollow profile spaces, the resulting torques or twisting forces are significantly reduced compared to the known hardware systems that are screwed or mounted externally.
