"Frameless sliding window"

The invention relates to a frameless sliding window with at least two displaceable in the closed position each other on the side edges overlapping and pushable against each other panes, which are arranged on lower in ^ the frame Plastic profiles are held displaceably and with in the lateral parts of the window frame provided sealing devices cooperate.

Frameless sliding windows have become known in which the two panes are held in a wooden frame, with grooves being provided in the wooden frame for moving the panes are. In these known sliding windows can - Move only one of the panes to the opening of the window while the other pane is held securely in its groove and only shifted to the side after removal of the slidable pane and after releasing the fuse, and if necessary can be removed from the 'frame, for example to be cleaned.

There are also known designs of frameless sliding windows in which the two panes can be moved, however for this purpose with a plastic border of the tenränder were equipped, v / obei the side edges in the closed position with correspondingly corresponding projections interlock to achieve a tight seal of the window. The outer side edges of the discs, which also wear plastic surrounds, grip in the Closing position of the penster in side rails made of plastic, which are equipped with a brush or lip seal are, as well as the upper and lower edges of the panes, with appropriate brush or lip seals the plastic rails interact.

Finally, frameless sliding windows have become known in which the panes in aluminum frame profiles with inserted plastic slide rails are guided. At this Design, the edges of the panes running in the plastic slide rails are provided with an aluminum border, which in turn cooperates with the plastic slide rail .

In summary, the known designs of frameless sliding windows can be divided into two groups, namely one in which only one disc can be moved during operation or in which two tracks with a

30981Q / 0425

End of the discs at the overlapping disc edges are equipped.

The known designs have the significant disadvantage that they are no longer either in two tracks allow a clear view through the openings covered by the panes or else or additional difficulties prepare when cleaning the panes, as in almost all ^ versions there is a sliding one for cleaning the panes Disc must be removed before the disc including the overlapping side edges are cleaned can.

It is the object of the present invention to design a sliding window of the type mentioned in such a way that without larger structural effort and taking advantage of the ease with which the panes can be moved in plastic profiles "Moving the windows to such an extent without removing them It is possible that the discs can only be completely adjusted by setting different shift positions can be cleaned and thus the removal of individual panes for cleaning is not necessary.

In order to solve the above problem, the mentioned sliding window is characterized according to the invention in that the panes free of edging in a known manner on ^:

one to the outside of the window Mn inclined and formed substantially "wider than the thickness of two panes The sliding surfaces of the plastic profile rest, which, v / ie known in a metallic, preferably made of aluminum existing profile rail is held, wherein in parallel to the disk plane facing profile parts of the lower and one upper metal rail each a sealing brush to the plant of the discs are included, and that on the upper metal rail as well as in the plastic sliding profile each one the outside pane at the beginning of the opening movement inwards pointing and one more each, lifting the inner pane from the outer pane at the beginning of the opening movement Guide piece are provided.

By being free of edging in a known manner Panes, an unobstructed view through the entire opening of the window to be covered by the panes is guaranteed and also a secure sealing of the window in the closed position is achieved, with a displacement of both 'Discs is possible without the discs coming into collision and without the disks with sliders received in corresponding bores, for example in the form of plastic uder rubber gliders.

The displaceability of both panes is made possible by the new arrangement without two distinct tracks in the form of sliding grooves

ο the like. allows the movement of the outside disc no obstruction due to the sealing brush provided At the beginning of the opening movement, the individual bristles are found to be in the closed state on the inner pane can be bent to the side when the sealing brush is lying on top

can without losing their sealing effect when restoring the closed position is somehow impaired '. .

With the new arrangement, the advantages are achieved that are known when using metallic profile rails, preferably consisting of aluminum, can be achieved, such Aluminum profile rails can either be embedded in wooden frames or can be designed as frame parts themselves are, so that practically an aluminum-glass sliding window arises.

The rails can be designed in several parts, especially if it is the arrangement of a double ^ window acts. Here you have the option of either having one common window for both »sliding windows that are arranged at a distance from one another To provide profile frames, or separate profile rails, For example, to be arranged in a wooden or plastic frame if the entire frame is not made of the metal profile target.

The guide pieces provided at the beginning of the opening movement "cause" both panes a slight inward displacement of these panes; thus come to the Έ ¹ öhr üngs pieces η to the plant without a forced guidance through any grooves or the like. is required. Such positive guidance is therefore not possible with the intended arrangement, because the pane continuously assumes a different angular position in relation to the outer edge of the window frame, at least in the first part of the opening movement until it is displaced by about a third of its width.

The new arrangement made possible by the mutual Ver-A Shifting the disks setting the various positions of the disks to each other, so that without difficulty the inner and outer surfaces of the panes including their covering edges can be cleaned without that one of the discs must be removed.

In a practical embodiment of the new sliding window it is provided that the Kuh.ststoffgleitprofil in one G-shaped section of the Hetallprofilschiene is held removable and to limit the sliding surface on

the highest area of the sliding surface is angled having. This configuration makes it easy to assemble, since the plastic sliding profile is inserted into the metal profile can be inserted v / ground and one also achieves a safeguard against the fact that the angled means the disks during the sliding movement from the sliding profile can step out.

It is advantageous if the guide pieces are designed as insertable wedges for repelling the outside pane and for lifting the inside pane at the beginning of the opening movements of the panes. are to be applied etzbaren wedges. During the inside repellent wedge stationary may be arranged, it is acc. to a preferred embodiment of the invention expedient to pieces, the inside wheel at the beginning of the opening movement of the outer pane Λ contrasting guide transverse to the plane of the pane slidably and transversely to its This design is advantageous because when the outer pane is opened after the inner pane has previously been opened, the outer pane is pushed outwards with its opening edge by the guide piece and the pane thus assumes an inclined position at which it is located e with a fixed arrangement of the inner pane from the outer pane

lifting guide piece would be prevented, or the J ¹ guide pieces for the inner and outer pane would have to be arranged so far apart that the outer pane would only point inwards after a greater opening distance had been covered, which, however, makes the sliding movement considerably more difficult. since the shift would have to take place against the action of the brush seal.

Particular advantages are achieved if the guide pieces held in the upper part of the metal profile rails are interposed of sections of the plastic sliding profile are arranged in "these. By the intermediate arrangement of the Plastic sliding profile with its G-guide surfaces rising towards the inside of the window ensures that the panes by arranging the sections of the plastic sliding profile against falling out and unintentional removal ^ can be saved in a simple form. The sections of the plastic sliding profile thus simultaneously form guide parts and stops for holding the panes in the frame. The use of the sections of the plastic sliding profile, as it is arranged in the lower metal profile rail, furthermore leads to a considerable simplification in manufacturing and manufacturing. It is useful if the lower and upper metal rails are of the same type are profiled, so that only one profile is necessary for the metal parts mentioned.

According to a further development of the invention it is provided that, in the closed position, the panes engage in opposing O-shaped profile projections of the metal profile rails equipped with brushes pointing towards one another. In this way, a circumferential sealing of the window in the closed position is achieved by means of sealing brushes which allow the panes to rest flexibly, even if the window has only been partially opened and the window M is locked in this position. For locking and securing, a receiving device for a pressing and securing device can be provided in the lower part of the metal profile, which consists of a tab that can be inserted into the cold device and a pressure piece with a detachable operating knurl held in a threaded hole in the tab. The pressing and securing device described has the advantage that it is removable and, on the other hand, at the same time represents a child safety device by removing the actuating knurl. '

In the drawing, the invention is explained in more detail using an exemplary embodiment.

Pig. 2 shows a horizontal section in a line representation through the window to Pig. 1.

Pig. 3 shows a partial horizontal section through the window after Pig. 1, but again with extremely shifted panes.

The Pig. 4 to 6 show various diagrams Opening positions of the discs of the penster after the pig. 1 to 3.

In the pig. 1 to 3 only the lateral or upper and lower metal profile rails are shown, which either can be designed as a frame by appropriate Porragebung, or added by appropriate wooden parts can be used to form the frame together with these.

One recognizes from the pig. 1 that the lower aluminum profile rail 1 has the same shape as the upper aluminum rail 3 except for a shoulder 2. In the aluminum rails 1 and 3 are plastic profiles via bends 4 and 5 6 or 6a added, the one located in the upper rail 3 Plastic profile 6a is designed to match the profile δ in cross section, but in senior length

2U3530

compared to the continuous plastic profile 6 only relatively is short.

The plastic profiles 6 and 6a have one to the outside of the window running inclined and substantially "wider than the thickness of the two panes 8 and 9 formed sliding surface 7, with the two aforementioned disks resting on the lower sliding surface. The disc 8 forms the inner disc, while the disk 9 is provided as an outer disk. f

The aluminum profile rail 1 differs from the profile sole 3, a bend 2 is provided, which serves to accommodate a water deflector 10.

On the outside legs 11 of the profile rails 1 and parallel to the disk plane pointing C-shaped profile parts 12 are integrally formed, which each receive sealing brushes 13, of which the in Pig. 1 recognizable brushes with the _Λ

Inner disk 8 cooperate and have corresponding long bristles.

The plastic profiles 6 and 6a v / iron at their ends facing the outside of the window in the form of fixed positions Wedge-shaped guide pieces 14, 15 which cooperate with the disc 9 when this in the direction of the Pi'oiles 1-5 (Fi / ;. 2) is opened. We continue to be with the ZuiKj to tofi'profil en 6 and 6a also wedge-shaped guide

pieces 18,19 connected, which with the inner disk 8 at whose movement in the direction of arrow 17 cooperate and the Inner disc 8 of the outer disc 9 at the beginning of the opening movement lift up.

The wedge-shaped guide piece 18 is in the plastic profiles 6,6a each arranged so that it can exercise lateral shifts in the direction of the inside of the window, wherein a spring 19 ensures that the guide piece 18 remains in contact with the inside of the outer disk 9. The guide piece 18 is held in the plastic profile 6,6a via a bolt 20, as shown in FIG. 1, wherein the spring, which acts on the guide piece 18 in the sense described, is arranged in a slotted sleeve 21. The guide piece 18 can thus execute movements transversely to itself and also pivoted about the bolt 20 will. ,

The length of the profile piece 6a is designed so that it extends at least over 'the space between the Guide pieces 14 and 18 extends so that these guide pieces are received by the plastic profile piece 6a can.

As shown in FIG. 1, is between the inclined surface 7 of the profile piece 6a and the upper edge of the two disks 8 and 9, there is a small margin, which allows that the disks in cooperation with the guide pieces 14 and 18 limited movements directed transversely to the plane of the disk can perform.

During the opening movement of the interior f disc 8 in the direction of arrow 17 (Fig. 2) is at the beginning of the opening movement, the disc 8 by interacting with the wedge surface of the guide pieces 18 from the outer disk 9 lifted off, thus preventing the panes from sliding on each other.

Is reached Yfenn a sufficient degree of opening of the inner disc 8, the outer pane can be moved in the direction of arrow 16 9, wherein aie until the end of the guiding λ pieces "14 and to some extent even beyond the bristles of the brush seal 13 located turns and with the Fixed guide pieces 14 cooperate, which ensure that the outer pane 9 is pushed inward and is thus lifted off the rails 1 and 3, whereby a sliding movement on the rails 1 and 3 is prevented and at the same time an obstruction of this movement by the sealing brush 13 or avoided is at least very substantially reduced.

309810/0425

In the case of the last-described movement of the outer pane 9, this leads to the profile part 12 as a result of the rejection a further displacement of the guide pieces 18 against the action of the spring 19> However, without the discs 8 and 9 can come into contact, since their space through the Guide pieces 18 is determined. The guide piece 18 can adjust itself in accordance with the inclination of the disk 9 and thereby pushes the inner disk 8 further on the sliding surface 7 of the plastic profile 6 inside.

When both panes in the direction of arrows 16 and 17 up to their stop on the delimiting side profile rails 22 have been moved (in Fig. 2 one of the rails 22 is shown) results in the position shown in Fig. ^ 3.

IJm to ensure in the described maneuvering procedures, that the discs 8 and 9 do not get out of contact with the plastic profiles 6, 6a, these have to limit the Sliding surfaces have a bend 23 which adjoins the highest area of the sliding surface 7 and which forms a delimiting approach. Through the interaction of the plastic profiles 6, 6a and their bends 23 will secure the panes 8 and 9 against unintentional removal or falling out created, because the distance between the bends 23 is chosen so that it is 8 and 8 even when the discs are inclined their removal is not permitted. Rather, it must be used for this purpose

309810/0425

the profile piece 6a must first be removed before the panes 8 and 9 can be removed from the frame. That Profile piece 6a can be designed as an insertion part, which is inserted laterally into the bracket 4, 5 can, if these angles 4 and 5 are not formed continuously, but corresponding recesses for inserting of the profile piece 6ä.

From the Pig. 1 can also be seen that on the plastic profile piece 6a a pressing device 24 is provided, before with a resiliently arranged support member against the inner pane 8 presses to this V / eise the upper end of the disks 8 and 9 against the leg 11 of the upper metal profile rail 3 to press.

The lateral metal profile rails 22 have C-shaped Vorspränge 25 which serve to receive the lateral brush like justifications 26 which engage around the side edges of the disks 8 and ύ 9 in the closed position and bring about in this way a secure seal.

From the Pig. 1 and 2 it can also be seen that in the lower part of the metal profile rail 1 a receiving device 27 according to Art an insertion sleeve is provided in order to receive a pressing and securing device 28. The pressing and securing device consists of a sleeve-shaped structure

receiving part 27 insertable tab 25a and one in this Tab held in a G-threaded hole pressure piece 29, which is provided with an actuating knurl 30 which. is detachably attached to the pressure piece 29, v / elches towards the disc 8 has a plastic coating 31, which with the disc 8 cooperates.

It can be seen from the Pig. That in all positions of the disks 8 and 9 these inclined by the interaction with the running sliding surface 7 have the tendency to always slide in the direction of the legs 11 of the metal profile rails 1 and 3.

From Fig. 3 it can be seen that the outer disk 9 cooperates with a brush seal 32, the bristles of this seal being understandably kept much shorter than the * bristles of the seal 13.

The possible intermediate positions can be seen from FIGS. at the opening of the shown in FIGS Sliding windows are possible to achieve different ventilation divisions and also cleaning positions.

In the closed position of the panes, the inside of the panes can be cleaned up to the overlap width the outer pane, which is covered by the inner pane. In the intermediate position shown in Fig. 4 can about half of the outside of the disc 9 can be cleaned, while in Pig. 5 position shown the other half is accessible for cleaning. In the position according to Pig. 5 is also one half of the inner pane 8 from the outside accessible, while with slight label movement of the outer pane ■ 9 in the starting position also the other half of the inner pane 8 can be cleaned from the outside. By corresponding further relative displacements of the disks against one another is both the second half of the inner pane 8 for cleaning and the Überdeckungsbereicii, which is in the closed position is covered from the outer pane by the inner pane.

In order to avoid that the slices possibly at extreme Overlapping positions come to rest on one another, additional guide pieces 18a can complement the guides 18 and 14a can be provided as supplements to the guides 14. These guide pieces would have to be in their training and arrangement correspond to the guide pieces η 14 and 18 already described.

As with other versions of sliding windows, the new design can also be used for hold-open and safety drive

lines of known type, for example toggles or lever locks of another type may be provided to the discs in to secure the different positions to each other. According to experience however, the securing and pressing device 28 shown in the drawing is sufficient for the disks to secure against unwanted displacement, since the pressure of this device from the respective immediately in front of the device located disc over the Pührungsteile 18 on the other disk is transferred.
