Description

[0001] The invention relates to a method for producing a sliding window element for a sliding window device according to the preamble of patent claim 1.

[0002] Very large, openable window formats can only be designed as sliding windows. In order to achieve a virtually seamless transition between living space and nature, there is often a desire for frameless glazing, i.e. glazing in which the frames are not visible. For this purpose, frame profiles are fully fitted into the floor, ceiling and walls, which support the window elements. Aluminum profiles are regularly used in this process, which absorb the considerable loads of the window elements. EP 3 095 946 A1 describes a sliding window device in which the frames are formed from a circumferential plastic profile, into which static elements are inserted on the floor side, which absorb the loads exerted by the window elements via force introduction supports.In the base-side profile part, rollers are also arranged in a straight line, on which the sliding window element rests and over which this window element can be moved.

[0003] This previously known sliding window device is characterized by a discreet, minimalist design in which the window pane appears to float frameless above the floor. EP 3 897 060 A1 describes a sliding window arrangement in which no channel is visible when the sliding window element is closed. By arranging a horizontal groove in the vertical sections of the surrounding pane frame on at least one side of the glass pane in continuation of the upper edge of the floor-side framing profile, into which a cover plate arranged on the floor-side frame part of the window frame projects, partially concealing this floor-side frame part and at the same time partially concealing the upper edge of the floor-side frame profile on this side of the glass pane, a continuation of the floor up to the glass pane is achieved, so that the pane appears to float above the floor.

[0004] The term "pane surround" refers to a rectangular frame profile that surrounds the glass pane of a window element. The term "frame profile" refers to one of the four sub-profiles of this frame profile that surrounds the glass pane. Each of the four sub-profiles is part of one of the four sides of the rectangular window element.

[0005] Particularly due to the existing tolerances of the laminated glass pane, the precise bonding of the side edging profiles to create a sliding window element proves to be problematic. The floor and ceiling edging profiles must be connected to the side edging profiles at exactly right angles. Dimensional deviations caused by tolerances in the laminated glass pane must be compensated for by the adhesive. This can cause the laminated glass pane to slip around different axes, which can compromise the geometry of the window element.

[0006] This is where the present invention comes in. The invention is based on the object of providing a method for producing a sliding window element for a sliding window device that enables simple, geometrically precise completion of the window element on site. According to the invention, this object is achieved by a method having the features of the characterizing part of patent claim 1.

[0007] The invention provides a method for producing a sliding window element for a sliding window device, which enables simple, precise completion of the window element on the construction site. By applying an adhesive, at least in sections, to the two opposite side edges of the laminated glass pane between the projections in a first step of the method, at least one connecting strip is applied to said adhesive in such a way that its cover surface lies on an imaginary plane running orthogonally to the projections, precisely straight contact surfaces are created, with all tolerances of the laminated glass pane being compensated for. The precise positioning of the connecting strip can be achieved, for example, using a stationary assembly device with calibrated feed devices.In a second step of the process, particularly on a construction site, a lateral edging profile is arranged on the at least one connecting strip of at least one side edge and glued to it, thereby ensuring its geometrically precise positioning. Preferably, the at least one connecting strip is made of plastic, particularly PVC.

[0008] In a further development of the invention, a corner connector is attached to at least two opposing projections of the edging profiles, via which the floor and ceiling edging profiles are connected to the lateral edging profile at at least one side edge. This supports the precise positioning of the lateral edging profile during installation.

[0009] In one embodiment of the invention, the corner connectors have at least one side wing on their center piece, which rests against a side edge of the laminated glass pane, onto which the lateral edging profile is slid and preferably screwed. This ensures a stable connection between the edging profiles.

[0010] In a further embodiment of the invention, the connecting strips have an adhesive surface covered with a removable protective film. This further simplifies the installation of the side edging profiles.

[0011] In one embodiment of the invention, the adhesive surface is formed by a double-sided adhesive tape. This simplifies the application of an adhesive surface with a uniform adhesive layer.

[0012] The present invention further relates to a device for carrying out the above method according to patent claim 6. The device comprises a frame which defines a rectangular area and is intended to receive a laminated glass pane, which frame is formed by two vertical frame profiles and two horizontal frame profiles on the floor and ceiling, wherein a sliding profile is mounted so as to be displaceable along the horizontal frame profiles, wherein the floor-side frame profile has a channel-shaped receptacle for a floor-side edging profile and wherein at least one slider is arranged which can be placed on a received laminated glass pane on its side opposite the floor-side frame profile and can be braced against it.This allows a laminated glass pane to be inserted into a floor-side edging profile, which is inserted into the groove-shaped holder and coated with adhesive, and to be fitted on the opposite side with a ceiling-side edging profile, which is also coated with adhesive and can be secured using the slider. By sliding the sliding profile, the connecting strips attached to this and the first vertical frame profile can be positioned precisely perpendicular to the floor- and ceiling-side edging profiles. They can then be bonded to the laminated glass pane using an adhesive applied to the side edges of the laminated glass pane, thus compensating for all tolerances of the laminated glass pane.

[0013] In a further development of the invention, the slider has a U-shaped contact profile that can be placed around a ceiling-side edging profile. This supports the correct positioning of the edging profile.

[0014] In one embodiment of the invention, at least one filler piece is detachably arranged on the first vertical frame profile and / or the sliding profile on their opposite sides, each filler piece having a contact surface running parallel to the sliding profile. This allows for the creation of adhesive-free areas on the adjacent side edge of the laminated glass pane, which can serve, for example, to accommodate a leg of a corner connector or a sealing element.

[0015] In a further embodiment of the invention, a holding device for securing and guiding a laminated glass pane in the frame is arranged on the frame. This holding device preferably comprises at least one suction cup for a force-fitting connection to a laminated glass pane. This enables reliable securing and easy handling of a laminated glass pane.

[0016] Further developments and refinements of the invention are specified in the remaining subclaims. An embodiment of the invention is illustrated in the drawings and described in detail below. They show: Figure 1 shows a schematic representation of an assembly device for producing a window element for a sliding window device in a preparation position a) in a front view; b) in a spatial representation; Figure 2 shows a schematic representation of the assembly device from Figure 1in a manufacturing position a) in the front view; b) in a three-dimensional representation; Figure 3 the schematic representation of a pre-assembled laminated glass pane a) in the front view; b) in a three-dimensional representation; c) in a detailed representation of the area "Z"; Figure 4 the detailed representation of the laminated glass pane from Figure 3 with bottom-side edging profile and corner connector; Figure 5 the schematic representation of the installation of a lateral edging profile to the laminated glass pane made of Figure 4 ; Figure 6 shows a schematic representation of an assembled window element.

[0017] The method chosen as an embodiment for producing a sliding window element for a sliding window device is divided into two process stages, a first, stationary process stage and a second, local process stage to be carried out on a construction site.

[0018] The first, stationary process step is carried out in the exemplary embodiment with the aid of an assembly device 9, which is Figure 1is shown. The mounting device 9 comprises a rectangular profile frame formed from two vertical frame profiles 91, 92 and two horizontal frame profiles 93, 94. A sliding profile 95 is displaceably mounted between the horizontal frame profiles 93, 94, parallel to the vertical frame profiles 91, 92. The floor-side horizontal frame profile 93 has a channel-shaped receptacle for a floor-side edging profile 2. A slider 96 is arranged on the ceiling-side horizontal frame profile 94, which slider is provided at its end with a U-shaped contact profile 961 for receiving a ceiling-side edging profile 3. A holding device 97 is arranged on a first vertical frame profile 91. The holding device 97 is formed from holding arms 971 which are pivotably mounted on both sides of the first vertical frame profile 91 and at the free ends of which a suction cup 972 is arranged.

[0019] In the first step of the process, a floor-side edging profile 2, which is provided with an adhesive, is first inserted into the groove-shaped receptacle of the floor-side frame profile 93. Subsequently, a laminated glass pane 1 is inserted into the floor-side edging profile 2 and fixed between the two holding arms 971, which are attached to the laminated glass pane 1 via the suction cups 972. A ceiling-side edging profile 3, provided with an adhesive, is positioned on the side of the laminated glass pane 1 opposite the floor-side frame profile 93. The floor-side edging profile 2 and the ceiling-side edging profile 3 have an identical length, which projects beyond the width of the laminated glass pane 1, so that both side edges 11 of the laminated glass pane 1 are formed with projections 21, 31 of the same length.The contact profile 961 of the slider 96 is placed on the ceiling-side edging profile 3, by means of which the laminated glass pane 1 is additionally held.

[0020] On both sides of the laminated glass pane 1, connecting strips 5, which in the exemplary embodiment are made of PVC plastic, are fixed to the first vertical frame profile 91 and to the sliding profile 95. An adhesive 7 is then applied to the two side edges 11 of the laminated glass pane 1. The sliding profile 95 is then moved towards the laminated glass pane 1 until the two floor- and ceiling-side edging profiles 2, 3, with their projections 21, 31, rest against the first vertical frame profile 91 and the sliding profile 95. In this process, the connecting strips 5 are moved into the adhesive 7, the excess of which is displaced laterally. After the adhesive 7 has hardened, the outer surface of the connecting strips 5 lies on an imaginary plane orthogonal to the projections 21, 31 of the floor- and ceiling-side edging profiles 2, 3.A double-sided adhesive tape 8 is then applied to this outer surface, the adhesive surface of which, facing the connecting strip 5, is provided with a protective film. Alternatively, the connecting strip 5 can also be provided with an adhesive layer on this outer surface, which is covered by a protective film.

[0021] In the second process step, the sliding window element is completed at its place of use on the construction site on the basis of the laminated glass pane 1 prepared in the first process step. In this case, in the exemplary embodiment, corner connectors 6 are attached to the projections 21, 31, as shown in Figure 4 shown. The corner connectors 6 have a central piece 60, to which two side wings 61, each provided with a threaded bore 62, are attached laterally opposite one another. These wings, together with the side strips 22, 32 of the floor and ceiling-side edging profiles 2, 3, delimit an insert 63.

[0022] After removing the protective film from the double-sided adhesive tape 8, a lateral edging profile 4 with its connecting pieces 41 arranged on both ends is inserted into the slots 63 formed by the corner connectors 6 arranged on the floor and ceiling projections 21, 31. The edging profile 4 is pressed against the now free adhesive surface of the adhesive tape 8 of the connecting strip 5. The lateral edging profiles 4, which are thus positioned exactly at right angles to the floor and ceiling edging profiles 2, 3, are finally screwed to the corner connectors 6 using screws 64, which are screwed into the threaded holes 62.

[0023] The method according to the invention enables the production of a sliding window element for a sliding window device, the completion of which can be achieved on site with minimal effort and maximum geometric accuracy. In particular, tolerances of the laminated glass pane have no impact on the completion of the window element on site with this method.
