Description

The invention relates to a frame window according to the preamble of claim 1, in particular to the fastening of a frame window in a frame.

A frame, such as that used for a basement window, is first inserted into the masonry before the window is inserted. The frame can be built into a brick wall, with fastening tabs built into the adjacent masonry to secure it. If it is a concrete wall, the frame can be cast into the concrete. The frame itself then serves as formwork for the window opening when the concrete is poured. To make it easier to install the frame, the frame window is only installed in the frame afterwards. In addition, the frame window is not so easily damaged when it is installed later.

Traditionally, the frame window is screwed to the frame on the outer frame. However, this has the disadvantage that screws and suitable tools are required. In addition, screwing is complicated and time-consuming. In addition, the screw connections are very difficult to loosen after a longer period of time, so that replacing a damaged window, for example, requires considerable effort.

Accordingly, the invention is based on the object of creating a frame window in which the assembly effort for fastening the window to the frame is significantly reduced.

This object is achieved by a frame window with the features according to claim 1.

Advantageous further developments of the frame window according to the invention are the subject of the appended subclaims.

The frame window according to the invention consists of a fixed rectangular frame with all-round stop strips for a window frame and is characterized by the fact that the window frame is detachably attached to the frame using plug connections. The provision of a plug connection makes assembly much easier, since no tools are required to mount the window in the frame. In addition, there is no longer any risk of the necessary tools such as screws for attaching the outer frame to the frame being forgotten or lost or having to be provided separately. In addition, the plug connection can be pre-assembled so that the frame window only needs to be inserted into the frame on site. A further advantage of the invention is that the frame window can be dismantled again even after a longer period of time without great additional effort, since, for example, no screw connections or the like can rust.

According to a preferred embodiment, the frame can be designed in the lower horizontal section with a support strip that has an inclined support surface. A lower frame strip of the window frame can then be supported on this support strip. In addition, the window frame can be swiveled from an inclined assembly position to a vertical position during assembly using the support strip as a swivel axis. Supporting the window on the support strip and assembling by swiveling the window from an inclined position to a vertical end position makes assembly work much easier. In addition, supporting the window on the support strip has the advantage that the relatively high weight of the window does not hinder the assembly personnel when inserting it into the plug connection and the window can easily be brought into a certain position when it is fitted into the plug receptacles.

A further advantage is that the weight of the window is supported on the support bar, as the areas in the frame that have to accommodate the plug connections do not have to be designed to support the entire weight of the window, as the majority of the window weight is supported on the support bar. This means that material and weight can be saved in the construction of the frame. In addition, the number of necessary plug connections can be reduced; plug connections are then only required in the upper area of the window to fix the window to the frame.

According to an advantageous further development, the lower frame strip of the window frame can have a downwardly protruding securing element that rests on a shoulder of the support strip located below the pivot axis. This also fixes the window in the lower area of the frame when it is installed. During installation, the window is pivoted from an inclined position to a vertical position so that the upper area of the window rests on the side of the upper and side stop strips in the pivoting direction and the lower area of the window rests with its opposite side on the shoulder of the support strip. This means that the window is virtually clamped between the stop strips at the top and the support strip at the bottom.

An advantageous further development measure is that the plug connection of the frame window consists of two components, a holder and a plug. This means that the frame and the window can each be equipped with one component, so that during assembly the connection of the window to the frame takes place as soon as the window is in its final position.

Advantageously, the plug can have at least one elastic snap-in element that can be snapped into the receptacle. The plug connection is thus fixed by simply snapping in, without any further assembly steps being necessary.

A further advantageous embodiment of the subject matter of the invention is that the plug and/or the receptacle itself can be snapped into the respective recess in the window or frame using a snap connection. This means that no tools are required when installing the plug or the receptacle. The individual parts can be easily pre-assembled and the assembly effort is significantly reduced.

Another advantageous development is that the plug or the receptacle is formed in one piece with the window frame or casing. If, for example, the window is made of a plastic profile, it is possible to integrate the receptacle or the plug into the shape of the window without any major construction effort. The window is then already equipped with part of the plug connection during manufacture and any pre-assembly effort is eliminated. This also applies to the casing, where part of the plug connection can also be integrated into the casing during manufacture, so that any pre-assembly effort is eliminated here too.

The frame of the frame window according to the invention can, for example, be made of polymer concrete. The one-piece design of the frame together with part of the plug connection would then be easy to implement.

Another advantageous option is that the plug or the holder is cast into the frame as a semi-finished product during the manufacture of the frame. This makes it easy to obtain

-5-

and way a firm, permanent connection of the part of the plug connection with the frame.

A further measure to improve the subject matter of the invention is the provision of a sealing profile running around the frame. This ensures that the window seals the interior when installed and that wind or rain, for example, cannot penetrate into the interior. When installed, the window presses against the sealing profile, which is thus kept under pre-tension. This also makes it possible to compensate for minor manufacturing inaccuracies in the frame or window without impairing the sealing function.

In order to keep the sealing profile under pre-tension when the window is installed, the sealing profile can be provided with an elastic sealing lip, which the window frame presses on when installed, as an advantageous further development. The sealing lip is bent depending on the pre-tension, whereby small inaccuracies in the frame or window can be compensated even better.

In order to further increase the sealing effect, a sealing profile can be provided in the lower frame section, which has two elastic sealing lips, the first sealing lip of which seals the window frame towards the interior, and the second sealing lip of which is arranged in the area between the first sealing lip and the securing element.

Finally, a further development of the subject matter of the invention is conceivable in that the securing element is designed as a securing pin, more precisely as a locking element that can be mounted in a locking hole in the window frame. This means that no tools are required to attach the securing element and the assembly effort is reduced even further.

Fig. 7 shows a detail of a second embodiment of a frame window with an alternative embodiment of a plug connection in cross section.

Fig. l shows an embodiment of a frame window, which consists of a rectangular window frame 1 into which a window 2 is installed. The window 2 consists of a glass 2a, which is glazed in a window frame 2b. The

—&ngr;—

Window frame 2b is in turn attached to an outer frame 2c. Any window can be installed in the outer frame 2c. For example, an openable and closable window with a turn and tilt fitting can be provided so that the window can be brought into an open, closed and tilted position in the normal way. The outer frame 2c is attached to the inner walls of the frame 1. It is attached using a plug connection not shown in Fig. 1, which will be discussed in the following description.

First, frame 1 will be described in more detail. As can be seen from
Fig. 2 shows, the frame 1 consists essentially of

two horizontal walls and two vertical walls, which together
form a rectangle. On the sides and top of the
A stop strip 3 is formed on the inside of the frame 1.
The upper stop bar is shown in section in Fig. 2. The frame 1 is also provided with a circumferential sealing profile 12

This sealing profile 12 is fitted on the sides and top
via piping in insertion grooves on the respective stop bar
The sealing profile is attached to the lower frame section
12 also fixed via piping in insertion grooves so that it

arranged remaining sealing profiles.

However, the lower sealing profile 12 differs from
the side and top of the stop bars 3
sealing profiles 12 in that it has two
Sealing lips 13 and 14. According to Fig. 5, recesses 1 a are also provided on both sides of the frame 1. Receptacles 40 for the plug connection are inserted into these recesses 1 a
which will be discussed in more detail later.

From Fig. 4, which shows a detail of the lower section of the
frame window enlarged in cross section, is to

that on the lower horizontal section 4 of the frame 1 a support strip 5 protrudes upwards, which is in

Longitudinally and is arranged slightly offset with respect to the stop bars 3. The support bar 5 has an upwardly facing support surface 7, which is slightly inclined and is bordered on both long sides by a shoulder 6.

The frame is cast in one piece from polymer concrete.

The outer window frame 2c will be described in more detail below with reference to Fig. 4. In this embodiment, the outer window frame 2c consists of a plastic hollow profile. The lower section has two outer hollow chambers 20, 22 and a central hollow chamber 21 in between. A locking hole 11 is provided in the central hollow chamber 21. A securing element 9 is located in this locking hole 11. This securing element 9 is designed as a pin which is provided with an elastic locking element 23 at one end. This elastic locking element is locked into the locking hole 11 under pre-tension. The locking element 9 is thus attached to the outer frame 2c. The locking makes it easier to install the securing element 9. In addition, no tools are required. The securing element 9 serves as a stop with which the window frame 2c can be supported on the shoulder 6 of the support bar 5 when installed and fixes the window 2 in the vertical position.

Now we will look more closely at the plug connection consisting of a plug 3 in the window and a receptacle 40 in the frame, with which the window is secured in the frame. As can be seen from Fig. 5, the plug 30 is secured to the outer frame by a locking lug 34, which is engaged in a recess 2e in the outer frame 2c of the window 2, and by a holding section 2f that encompasses one end 37 of the plug. The receptacle

40 is fixed in a recess la of the frame via stops 42, 43. To connect the window 2 to the frame 1, a locking element 32 protruding from the plug 30 snaps under pre-tension into an opening 41 provided for this purpose in the holder 40.

Fig. 6a and 6b show the plug 30 as a single part. The plug 30 is made of plastic. It has a base 31 which rests against the outer frame 2c. An elastic wing 33 extends at an angle from one end of the base so that it forms a leg thereto. At the end of the wing 33 the laterally protruding locking element 32 is provided. The locking element 32 serves to lock into the receptacle 40 when the window 2; is mounted, which will be described in more detail later. As can also be seen from Fig. 6b, an angled arm 35 extends approximately at right angles from the base 31. The locking lug 34 is formed at the end of the arm 35. With the help of this locking lug the plug is mounted in the recess 2e of the outer frame 2c. The plug 30 is installed in the window frame 2c as follows. The plug 30 rests with its base 31 on a flat side section 2d of the outer window frame 2c. The angled arm 35 of the plug 30 extends into the recess 2e of the outer window frame 2c, with the locking lug 34 snapping into an edge of the recess 2e under pre-tension. Furthermore, the end 37 of the plug 30 is pushed into the holding section 2f that surrounds this end, so that the plug is completely fixed in this position.

The receptacle 40, which is also made of plastic, is located in the recess 1a, as shown in Fig. 5, which is provided laterally in the upper area of the frame 1. The opening 41 is aligned with the window 2, with its dimensions corresponding to the dimensions of the locking element 32 of the plug 30. The receptacle 40 has essentially an S-shaped cross-section, with the upper and lower legs of which are designed to be so elastic that the receptacle 40 can be compressed in

-10-

the recess la of the frame 1 can be mounted and is firmly seated in it in the relaxed state. In addition, stops 42, 43 are provided at the ends of the two legs, which are directed outwards at an angle towards the frame wall. The recess la of the frame has corresponding angular bevels against which the stops 42, 43 come into contact. In this way, the holder 40 is secured by the stop 43 against being pushed out towards the window and by the stop 42 against being pushed out in the opposite direction. This makes assembly easier because no tools are required to secure the holder in the frame.

The installation of the window into the frame will be explained in more detail below. The installation is possible without tools, as all individual parts can be assembled using plug-in or snap-in connections. The window is pivoted from an inclined installation position, as shown in Fig. 4A, into a vertical end position, as shown in Fig. 4, in which it is firmly connected to the frame using the plug-in connection. According to Fig. 4A, the window in the inclined installation position rests with its underside flat on the inclined support surface 7 of the support bar 5. The support bar 5 is located between the securing element 9 and a downwardly projecting end section of the outer frame 2c. The window is then pivoted in a direction according to arrow A and thus brought into a vertical position. The higher edge of the inclined support bar 5 serves as the pivot axis.

The angled wing 33 of the plug 30 located in the window 2 protrudes so far from the outer window frame 2c that when the window 2 is pivoted in the frame 1 it rests against the inner wall of the frame under pre-tension. When the window 2 reaches its vertical end position according to Fig. 4, the

-11-

Locking element 32 opposite the opening 41 of the holder 40. The pre-tensioning force under which the elastic wing 33 is pivoted presses the locking element 32 into this opening 41. The window 2 is thus fastened to the frame 1 in the upper area. According to Fig. 4, the outer frame 2c of the window 2 rests against the side and upper stop strip 3 in its final position.

The lower section of the window frame rests on the edge of the support surface 7 of the support bar 5, which serves as the pivot axis. In order to prevent the window 2 from being moved beyond the vertical end position when pivoting in the pivoting direction, the locking element 9 is arranged in the lower section of the outer frame 2c. When the window is in its end position, the locking element 9 rests on the shoulder 6 of the support bar 5 and fixes the window in the pivoting direction. The window is thus firmly mounted in the frame.

The outer frame 2c of the window 2 presses on the sealing profiles 12 in the end position. As shown in Fig. 4, the lower section 2g of the outer frame 2c presses on the sealing lips 13, 14 at the same time. The first sealing lip 13 comes into contact with a downwardly projecting projection arranged on the outer edge of the outer window frame 2c and is pressed downwards by it. This creates a seal between the window frame and the casing. The second sealing lip 14 is located between the first sealing lip 13 and the securing element 9. It is designed to be slightly larger so that it is held under tension by the lower section 2g of the outer frame 2c and can thus fulfill its sealing task.

It should also be noted that the window according to the embodiment described above can also be dismantled just as easily, as will be explained briefly below with reference to Fig. 5. The sash

-12-

3 3 of the plug 30 has an extension 36 at its end. Even when the window is mounted in the frame, this extension 36 is accessible using an elongated tool such as a screwdriver. The screwdriver is placed between the frame 1 and the extension 36 and pivoted so that the sash 33 is moved against its pre-tension, so that the locking element 32 is removed from the opening 41 of the holder 40. The window can now be brought from the end position to the original assembly position by pivoting it in the direction opposite to arrow A in Fig. 4A and then removed.

An alternative embodiment will then be explained in more detail with reference to Fig. 7. In contrast to the previous embodiment, this embodiment is not a plastic hollow profile frame window, but a window with a simple metal frame. Since this embodiment is basically the same as the previous embodiment except for the plug connection, only the plug connection consisting of a plug 60 and a receptacle 50 will be discussed here. The receptacle 50 in Fig. 7 corresponds essentially to the receptacle 40 of the previous embodiment and has an opening 51 for receiving a locking element. However, the receptacle 50 is inserted via locking lugs 52, which are arranged on the end pointing towards the frame 1, into a recess provided for this purpose, which is designed in a step shape. The plug is a wedge-shaped, angled component which has a locking element 62 approximately at right angles to a base 61. The plug 60 is not housed in the outer frame of the window, but is inserted as a separate component with its locking element 62 in the opening 51 of the holder 50, whereby the base 61 rests on the inside of the frame 1. The wedge-shaped plug 60 lies with its front side, which

-13-

open angle, on an edge of the window 2 and fixes it in the frame 1. The window is installed in the frame as follows: First, the holder 50 is inserted into the recess in the frame by pressing it together slightly and pushing it into the recess under pre-tension. The locking lugs 52 protrude behind the side wall of the frame and clamp the holder 50 in the recess when it is released. The window is then moved from an inclined installation position to a vertical end position and held in this position. The plug 60 is then inserted into the holder 50, with the wedge-shaped end wall resting on an edge of the window and the window is thus fixed in this position.

Finally, it should be pointed out that it is also possible to attach the window to the frame using three or more plug connections, with at least one plug connection being arranged in the upper and lower areas of the frame, so that the window can only be attached to the frame using plug connections. This would make both the support strip in the lower area of the frame and the securing element on the outer frame 2c of the window 2 unnecessary.
