Technical field

The present invention relates to a connecting device for connecting a Window frame with a frame connection part according to the preamble of independent claim.

State of the art

Nowadays it is common to have window units with window frames and one or ready to assemble several window sashes in window factories. On the Construction sites are the window frames with or without sash in the window cutouts built-in. For the installation of the window frames are the window cutouts or Masonry openings are usually provided with prepared frames. In this the window frames are used in such a way that the window frames with their outer margins to corresponding opposite sides of the Frame connecting parts forming the frame are arranged abutting.

In connection with the present description and the claims the generally straight sides that form the outer periphery of a window frame referred to as the outer edge of the window frame. That through an outside edge leading and at right angles to the window frame level (also referred to as window level) arranged level is called the outer edge side level, and the Directions parallel or perpendicular to this outer edge side plane are considered to Outer edge side referred to parallel or vertical directions. The on the window frame or parts of the frame border adjoining its outer edge sides are referred to as frame connectors. They each point at least a flat opposite side with the window frame inserted into the frame is arranged parallel to an outer edge side, this opposite side and the outer edge side positioned with respect to each other in an abutting arrangement are. Here, an opposing arrangement of two Sides understood that they either directly touch each other side by side, or that they are each in the opposite direction to one arranged between them Toast the intermediate piece. Frame connection parts can in particular window frames of further windows, roller shutter boxes, frame extension parts, Intermediate frame parts, edge frame parts, facade elements or window ledges.

For connecting a window frame made of plastic hollow profile parts with inserted metal profile parts is formed, it is with a frame connecting part known, the outer edge of the window frame and / or with this connecting opposite side of the frame connection part with profile cross sections provided that after inserting the window frame in a with the Frame connection part provided frame frame perpendicular to the window plane (i.e. parallel to the outer edge side) positive connection between the Window frame and the frame connector is created. For this purpose can e.g. the outside edge of the window frame with a perpendicular from it Edge protruding outwards, running in the longitudinal direction of the edge be provided, while in the corresponding opposite side of the Frame connecting part, to which this outer edge side after the installation of the Abuts the window frame, a groove corresponding to this comb is formed. At the Installing the window in the frame surrounds the comb into the groove inserted. This makes one perpendicular to the window plane and transverse to the Longitudinal direction positive connection between the window frame and the Frame surrounding created.

It is also known for plastic windows to facilitate the alignment of the Window frame in the frame on the inside of an elastic resilient groove wall to form a wrap-around bar and the comb with a Retaining edge to be provided. The wrap bar then clicks after the comb completely in the direction of the groove depth (i.e. perpendicular to the longitudinal direction of the groove) into the groove is inserted behind the retaining edge so that the comb is temporarily in the Groove is retained. If necessary, the comb can be turned in the opposite direction Groove depth pulled out of the groove and in again after any alignment In the direction of the groove depth.

After inserting the window frame and aligning it in the The window frame is surrounded by screws with the adjoining frame Frame connectors connected to create a connection between the To create window frames and the frame connecting parts, each against the Direction of impact between the abutting sides of a Frame connector and the window frame is tensile. So that these Train connection to the considerable, e.g. caused by wind loads Withstands tensile forces between the window frame and the frame connector can occur, the screws through the window frame and in particular through the metal profile arranged in the hollow plastic profile be screwed. This is associated with considerable effort and cumbersome.

Presentation of the invention

The object of the invention is to provide a connecting device for connection a window frame with a frame connection part, the large tensile forces withstands between the window frame and the frame connector and still a quick, easy installation of the window frame in one with the Frame connection part provided frame surround allows.

The solution to the problem is defined by the features of claim 1. According to the invention comprises a connecting device for connecting a Window frame with a frame connection part such that in the connected state the window frame with at least one outer edge side in abutting Arrangement is arranged with respect to an opposite side of the frame connection part, projection-like connecting means, the tensile on a first side of the outer edge side of the window frame and the opposite side of the frame connection part formed side pair attached or tensile attached to this first side are. The connecting device further comprises one on the other, second side this side pair arranged connecting groove. The connecting groove is on the second side firmly attached or formed in its surface that it firmly especially in the direction perpendicular to the side surface with the second side is connected and runs parallel to the surface of the second side. She points at least one connection lot. The connecting groove and the projection-like Connection means are designed and arranged such that the projection-like Connecting means can be inserted into the connecting part of the connecting groove, wherein in this connecting part from the connecting groove transverse to the longitudinal direction of the groove, i.e. especially against the direction of impact between the window frame and the Frame connection part, are held in place by positive locking. This will in case of projecting connection means attached to the first side in a tensile manner after the introduction of these connecting means in the connecting part of the The connecting groove is a positive fit that acts tensile against the direction of impact Connection between the window frame and the frame connection part created.

By means of the connecting device according to the invention, one with a Window unit provided with window frames is extremely easy to assemble on site or built into a frame: only the Window unit inserted into the frame, the projection-like Lanyards in the correspondingly formed connecting parts of the Connection grooves introduced and, if the projection-like connecting means still not attached to the window frame or the frame connector on the first side are attached to it. It is no longer necessary to use the window frame by means of screws leading through the frame to the adjacent ones Screw the frame connection parts of the frame frame tightly around a tensile Connection between the window frame and the frame connection parts create. The tensile connection is already in the connecting parts of the Connection grooves inserted or suspended projection-like Lanyard guaranteed. As is common with two-piece connectors, can the projection-like connecting means either on the window frame or on Frame connector and the connecting grooves on the other of each other parts to be connected.

By not after inserting the window frame into the frame enclosure is more necessary to fasten screws through the frame screw, can by means of a connecting device according to the invention Window frames are mounted in a frame so that after the No mounting screws at all on the window frame or on the Frame are more visible. In one according to the invention Fastening device, all fastening screws can be arranged in this way that they are hidden inside the connector after assembly are. This is a further advantage of the invention over previously known ones Connecting devices of the type mentioned. In the latter were either the mounting screws visible from the outside after assembly or they had to be covered by an additional cover.

Advantageously, the connection means attached to the window frame (i.e. the projection-like connecting means or the connecting grooves) of the Connection device according to the invention already in the course of producing the Window frame, e.g. in a window factory, attached tensile to the window frame. These connecting means can be an integral part of the window frame be formed, which are connected to the window frame in a tensile manner. It can however, connecting means are also provided in the form of separate connecting parts be e.g. by means of screws, rivets, connecting pins or other suitable Art tensile attached to the window frame. In a similar way, the connecting means attached to the frame connecting parts Connection device according to the invention already in the manufacture of Frame connection parts are firmly attached to these.

In the case of a plate-shaped frame widening on the construction site, none Screws may need to be screwed into this frame extension the frame widening with a comparatively thin mounting plate (Anchoring plate) for the screws. In the factory, the screws relatively easily with the required accuracy in this thin mounting plate be screwed. The rest of the plate-shaped frame widening can then be made from inexpensive foam. This can save costs and at the same time improves the insulation ability of the frame widening plates become. In addition, since the material for the mounting plate is much heavier than the foam material, weight can be saved, which in turn is advantageous for the transport and assembly of such frame extension plates.

The connecting groove can be directly in the surface of the second side (on which the Connection groove is arranged) from the outer edge of the window frame and the opposite side of the frame connecting part formed side pair. This variant of the invention is particularly suitable for window frames that in Are essentially made of hollow profile parts, since they are often already included Grooves are provided in their outer sides.

However, it is also possible on the second side of the outside edge of the Window frame and the opposite side of the frame connector formed Side pair (on which the connecting groove is arranged), one with a to attach the corresponding connecting groove. For this Suitable purposes are e.g. Groove pieces that are of the type with a T-shaped Groove cross section provided mounting rails are formed. Such Fastening rails are in construction under the name "Jordahl rails" widespread. This variant of the invention is particularly for window frames suitable, which are made of solid, such as Wooden window frames.

The projection-like connecting means preferably comprise at least one Connection head, which is in the manner of one from the first side to which it is attached protruding protrusion is formed with a maximum width that at least one point away from the side surface is larger than one closer minimum width at the side surface. Here is the connecting groove at the same time designed in such a way that the groove cross section in its connecting part at a deep point wider than the maximum width of the connection head and at one higher point is narrower than this maximum width, so the connection head can be inserted into the connecting part of the connecting groove such that it is in this Connection part from the connecting groove across to the longitudinal direction of the groove Form fit is held. In the course of the present description and the Claims is always the width in the direction of the width of the connecting head Understand the width of the connecting groove when inserted into the connecting groove or is attached.

Projection-like connecting means, which are designed in the manner of a connecting head are in the case of a connecting groove with two groove side walls, each with one Wrapping bar are provided, held by both wrap bars at the same time.

Basically, other forms of projection-like are also Lanyards possible. In particular, the projection-like Connecting means can also be designed such that in the case of a connecting groove with two groove side walls, each provided with a wrap-around bar, one of the projection-like connecting means only from one and the other projection-like connecting means only from the other wrap bar be held.

The connecting groove further preferably has at least one with a recess provided insertion section, the recess and the connecting groove in such a way are designed and dimensioned that the connecting head through this recess insertable into the connecting groove transversely to the longitudinal direction of the groove and then in the connecting groove in the longitudinal direction of the groove away from the insertion section Connection section is slidable to the connection head in the tensile Hook in the connecting groove. The recess can be used as a groove widening on the Narrow point of the connecting groove can be formed such that the groove cross section in the insertion section is wider than the maximum width of the Connection head, so that the connection head in the insertion towards the Groove depth can be inserted transversely to the longitudinal direction of the groove into the connecting groove. The But recess can also in such a way in a side wall of the connecting groove be designed so that the connecting head in the insertion section transverse to Longitudinal direction and insertable into the connecting groove transversely to the direction of the groove depth is.

The connection head and the connection groove in the connection part can cross have a substantially T-shaped cross-sectional shape to the longitudinal direction of the groove. In the connecting part, the connecting groove then has one to the second side in the essentially parallel groove bottom, two arranged at right angles to the groove bottom parallel groove side walls and two wrap-around strips, one on the groove bottom distant point at right angles from the two groove side walls (and thus parallel to the Groove bottom) protrude into the groove. The is below the wrap-around strips Connection groove wider than the maximum width of the connection head in the direction of the Groove width. The groove between the two wrap bars is narrower than this maximum Width of the connection head. A connection head with a T-shaped cross section can be designed as a molded part that has a plate-shaped width in the direction of the groove width Lot and has a columnar, narrow in the direction of the groove width. The maximum width of the connector head is then determined by the width of its plate-shaped section and its minimum width by the width of its columnar section determined. The connecting head is advantageous formed such that after attaching the connection head to the first The plate plane extends parallel to the surface of the first side and the columnar section between this side surface and the plate-shaped section is arranged. The connecting head can be designed as a one-piece molded part. However, the use of multi-part connection heads is also essential possible. When the connection head is inserted into the connection section, grasp the two wrap around the plate-shaped part of the connecting head so that it is in Direction against the groove depth is held positively and not out of the groove can be pulled out.

Instead of T-shaped cross-sectional shapes, others can also be used for positive Connections suitable cross-sectional shapes for the connection heads and the Connecting grooves can be selected, e.g. dovetailed Cross-sectional shapes.

The plate-shaped part preferably has the shape of a circular disk. Such a Connection head is particularly simple and inexpensive to manufacture.

However, the plate-shaped part can also be designed such that it is much longer than it is wide and that it is one axis of rotation perpendicular to the side surface is rotatable. Such a Connection head can then be used for different groove widths by the plate-shaped section is rotated into a rotational position in which its width in Direction of the groove width corresponds to the respective groove width. For this purpose, the plate-shaped section e.g. be rectangular or elliptical. For the purpose of However, the plate-shaped section can also adapt to different groove widths be arranged eccentrically on the columnar part of the connecting head.

According to a preferred embodiment of the invention, the Connecting device designed for use for a window frame, the Contains plastic hollow profile parts with inserted metal profile parts. In case of a Connecting device with a connecting groove arranged on the window frame is this preferably by means of tensile fasteners with at least one Connected metal profile part. In the case of a connection device with on Projection-like connecting means attached to window frames are preferred these projection-like connecting means by means of tensile connecting means connected to at least one metal profile part of the window frame. The Connecting means for connecting the projection-like connecting means or the Connecting groove with the metal profile part can be a metal screw, a metal pin or comprise other suitable tensile connection means. The of the Connection device then exerted tensile forces on the window frame transferred to the stable metal profile, so that the connecting device withstands comparatively large tractive forces.

Ways of Carrying Out the Invention

1-3, an elongated profile part 10 of a window frame is shown, which means a connecting device according to a preferred embodiment of the invention is connected to a plate-shaped frame widening part 20. The Frame widening part 20 is part of a frame enclosure, in which the Window frame is used, being on the side next to the one in the vertical direction extending edge-side profile part 10 of the window frame, with its end face abutting this is arranged. In Fig. 1, the profile part 10 and that Frame extension part 20 in the connected state in a cross-sectional view shown along the line A-A from above. Fig. 2 shows a partial side view of the Frame profile part 10 from Fig. 1 in isolation, i.e. before connecting to the Frame widening part 20, from the side of the frame widening part 20, and FIG. 3 shows an analog partial side view of the frame widening part 20 1 from the side of the frame profile part 10.

The frame widening part 20 has substantially the same thickness as that Window frame profile part 10. Its facing the window frame profile part 10 End face is with a plastic profile part 50 with an H-shaped profile cross section. Mistake. The H-profile part 50 has a middle between two flat side strips 52, 54 arranged and connecting these flat connecting bar 56, wherein the width of this connecting bar 56, the thickness of the frame widening part 20 (and thus also the plastic profile part 10) and the side strips 52, 54 are arranged parallel to one another and at right angles to the connecting bar 56. The Connection strip 56 of the H-profile part 50 lies on the frame profile part 10 facing end face of the plate-shaped frame widening part 20 on and essentially completely covers them. The two side strips 52, 54 of the H-profile part 50 each lie with half on the parallel to the window level Side faces of the frame widening part 20 on, while the other halves in front the installation of the window frame parallel to the side surfaces on the front of the Projecting frame extension part 20 beyond. This protruding plastic strips On the one hand, 52, 54 make it easier to align the window frame during installation the same in the frame enclosure provided with the frame widening part 20. On the other hand, after the window frame has been installed, they lie on the window level parallel side faces of the frame profile part 10 and then ensure a perpendicular connection to the window plane acting connection between the Frame profile part 10 and the frame widening part 20.

On the end face of the Frame widening part 20 a plurality of molded parts are firmly attached, which as connecting heads 30 for the connecting device according to the invention serve. Such a connection head 30 can be seen in FIGS. 1 and 3.

The connecting head 30 is designed as a one-piece molded part made of metal and has a circular cylindrical column 32 which is perpendicular to the front of the Frame extension part 20 protrudes from. At his distant from this face At the end of the column is a plate-shaped circular disk 34 concentric with the column integrally formed, the plate plane being arranged parallel to the end face. The The diameter of the circular disc 34 is much larger than the diameter of the circular cylindrical column 32. In a perpendicular to the face and the window plane Cross-sectional plane, the connecting head 30 thus has a T-shaped cross section, such as can be seen in Fig. 1. Through the center of the circular disc 34 and the column 32 a passage is formed therethrough. The connection head 30 is by means of a through this passage and vertically through the connecting strip 56 of the H-profile part 50 leading through far into the frame widening part 20 Screw 38 firmly connected to the frame widening part 20. On the Connecting head 30 is also the H-profile part 50 on the screw 38 Frame extension part 20 attached.
