Window

Description

The invention relates to a window, in particular a basement window with a window pane made of single or multiple glass and a frame that can be firmly inserted into a wall, partition or similar opening. 5

Such a window without a frame surrounding the window pane and pivoting or tilting with it has the advantage that a relatively large light entry opening remains relative to the wall, partition or similar opening.

With windows, it is usually desirable that the light entry opening has as large a proportion of the total area of the window as possible, so that a high level of light is guaranteed in the rooms behind it. This is particularly important for basement windows, as it is usually difficult to provide basement rooms with sufficient natural light from outside.

The windows of the type mentioned at the beginning allow a lot of light in, but they cannot be opened. This has the disadvantage that the rooms behind them cannot be ventilated through such windows. Living rooms or basement rooms in particular should, however, be ventilated regularly. Furthermore, the windows described at the beginning do not offer the possibility of passing objects or materials through them or even temporarily leading a hose, power cable or the like outside. Finally, the windows of the type described at the beginning can only be cleaned under great circumstances or in individual cases not at all. This is because the outer surface of the window pane is often very difficult to access. Just think of basement windows with narrow light openings.

■ ··

shafts in front of them or on windows that are installed on higher floors without an associated balcony. Finally, replacing a damaged window pane on these windows often causes considerable difficulties, as the window pane is firmly inserted into the wall opening together with the frame.

Windows are also known which comprise a frame, a window pane and a casement, whereby the window pane arranged in the casement is opposite the

Frame is tiltable and/or pivotable. Such windows can be opened, but the opening for light to enter remains reduced due to the sash frame. The known windows usually require a relatively strong sash frame. The sash frame must on the one hand hold the window pane and preferably increase the stability of the window pane and on the other hand offer fastening options for the fittings required for tilting and pivoting. Furthermore, such windows, 0 which have a sash frame that is precisely adapted to the frame

require, complex to manufacture. Therefore, windows of the type mentioned above are often installed in stairwells, storage rooms or the like, but they cannot be opened for cleaning or ventilation purposes. The conventional tilt and/or pivot windows described above are too complex for such applications.

Finally, conventional tilt and/or pivot windows are unsuitable for small wall openings due to their sash frames that narrow the opening for light to enter.

The need to install windows even in very small wall openings goes so far that one often settles for a light entry opening that is more reminiscent of a "loop slit".
35

Furthermore, basement windows in particular pose a significant risk of burglary. On the one hand, a large opening for light to enter can be tempting for potential burglars, but on the other hand, tilt and/or pivot windows can

in the open position can be opened by force in a relatively short time.

The object of the present invention is therefore to further develop a window of the type mentioned at the outset in such a way that a burglar-proof window can be produced in a simple and cost-effective manner that can be opened easily and reliably and kept open, for example, for cleaning or ventilation.

This problem is solved in a surprisingly simple manner by the features of claim 1. Advantageous further developments are described in the subclaims.

A key idea of the invention is to mount the window pane framelessly on or in the frame so that it can be rotated and/or tilted. This eliminates the need for the usually bulky, expensive and light-absorbing sash frame.

This idea combines the advantages of the non-opening window described above (large opening for light entry, low manufacturing costs, etc.) with the advantages of the conventional tilt and/or turn window described above (ventilation and cleaning options, etc.), but without taking on the serious disadvantages of these two window alternatives.

Another important idea is to provide an edge protector on at least one edge of the window pane, in which the corresponding edge of the window pane is framed. This significantly reduces the risk of injury from a window pane that is tilted or swiveled relative to the frame. Furthermore, the risk of damaging the window pane when it is open is effectively reduced by the edge protector. Further advantages arise from the fact that packaging material can be saved for transport and storage purposes thanks to the edge protector that is already present.

If the edge protection is firmly connected to the window pane, in particular glued, it can also help to stiffen the window pane if it is made of a suitable material. Furthermore, forces can act on the window pane via the edge protection.

It is particularly advantageous to arrange bearing pins on the edge protection which are or can be accommodated in complementary pivot bearing bushes on the frame so that the window can be rotated or tilted about the axis defined by the bearing pins. In this case, the frameless mounting of the window pane is achieved in ^a surprisingly simple and yet reliable manner. The connection between the bearing and the window pane is ensured by the edge protection, or the edge protection can already be regarded as part of the bearing. Of course, it would also be conceivable to provide the bearing pins on the frame and to form complementary pivot bearing bushes on the edge protection. The basic principle is that the edge protection, which is firmly connected to the window pane, forms part of the bearing.

Irrespective of this, the edge protection can have a continuous channel extending parallel to the associated edge of the window pane, into which an elongated profile, in particular a round rod, can be inserted. This can, on the one hand, contribute to increasing the stability of the edge protection and thus of the framed window pane.

On the other hand, a round rod with both ends protruding over the edge protection can be used to form bearing pins, which can be accommodated in complementary pivot bearing bushes on the frame. This type of bearing is suitable for both tilt and pivot windows and, in a particularly impressive way, also for tilt/pivot windows. It is particularly interesting for the pivot function, since such a round rod, together with the corresponding bearing bushes, forms a smooth-running bearing and, in addition, the lever forces which

is able to absorb the forces acting on the bearings through an open rotating window.

It is also conceivable to provide two round bar sections instead of the continuous round bar, which are inserted into the edge protection at the front and protrude above it. The bearing pins thus formed can be inserted into the corresponding bearing bushes on the frame in the manner described.

It is particularly advantageous if the bearing pins are formed in one piece with the edge protection. In this case, ! corresponding bearing bushes are provided on the frame, which accommodate the front ends of the edge protection designed as bearing pins. In this design, the bearing pins are formed in a particularly simple manner. The connection between the bearing and the window pane is very direct. In an advantageous design, the bearing pins formed in one piece with the edge protection have an approximately semi-cylindrical shape. They are pivotally mounted in cylindrical bearing bushes on the frame. The bearing bushes each have a circumferential opening that only allows the window pane to be removed in a certain angular position.

This specific design of the bearing is simple and yet reliable. In addition, it is particularly burglar-proof. Depending on the orientation of the peripheral openings of the cylindrical bearing bushes, the angle position at which the window pane should be removable from the frame can be determined. In conjunction with the locking or arresting devices to be described later, the window pane can only be removed from the inside. Removing the window pane from the outside is not possible.

In a particularly advantageous embodiment, the edge protection has a U-profile section. The associated edge of the window pane can be accommodated between the legs of this section. This profile shape appears to be suitable for the edge protection.

particularly suitable because it is rounded on the outside (risk of injury) and because it also allows for the installation of a swivel scissor. It also provides sufficient space on the inside to form a firm connection with the window pane.

If the window pane rests against or on the frame with the edge protection of at least one edge, at least when closed, further support is guaranteed.

It can also be advantageous to provide edge protection all the way around. This increases stability in a particularly advantageous way. The risk of injury from the edges or the risk of damaging the edges of the window pane itself is thus practically eliminated. Furthermore, the window panes can be stacked on top of one another or leaned against one another for transport or storage purposes without the need for additional packaging.

0 The locking device advantageously consists of a plate which is attached to the edge protection and a window handle with a locking lug, in particular a double locking lug. The window handle is arranged so that it can rotate on the plate. In the closed state, the locking lug engages in corresponding grooves on the frame. By pivoting the window handle, the locking lug can be disengaged from the frame. The locking device is characterized by the fact that it is simple in construction and can be attached directly to the edge protection. Furthermore, it does not require any special fittings or counter bearings on the frame.

In general, it is advantageous to arrange the tilt bearings for supporting the window pane on the frame on the inside of a side or lower section of the frame. This means that the tilt bearings do not protrude on the side of the frame facing the interior. Likewise, the window pane is completely housed in the frame in the closed position and does not protrude into the room, as is usually the case with conventional windows. This means that the

Windows can be easily stacked on pallets. It requires little space and little packaging material.

If the window pane rests with its lower edge on the inside of a lower section of the frame to form the tilting bearing, preferably so that it can be removed upwards, and is held tiltable in the frame by stops assigned to the lower edge, this has the advantage that the window pane does not have to be provided with fittings for mounting in a hinge in this further development, but is held tiltable with its lower edge in the frame directly and without any fittings. Furthermore, with this design of the tilting bearing, the window pane can be easily removed from the frame after releasing the locking device. This makes cleaning or replacing a damaged window pane much easier.

Similar advantages are achieved by tilting the window pane with its lower edge resting on support bodies that are each rotatably mounted on the side sections of the window frame, preferably around an axis parallel to the lower edge of the window pane. Because the support bodies are rotatably mounted, the window pane can be tilted particularly easily.

Furthermore, with this alternative tilting bearing, the window pane can be tilted up to against the frame plane after releasing the locking device.

To prevent rainwater or draughts from entering, the frame should have a circumferential seal against which the window pane fits tightly when closed.

The locking device, which holds the window pane in a closed or tilted position relative to the frame, can have a limit for a maximum tilted position and/or additionally have means that allow different tilted positions between the closed position and the maximum tilted position of the window pane. The limit prevents the window pane from falling out of the

Frame when tilting. Tilting positions with a smaller opening angle of the window pane compared to the maximum tilt position are useful in several respects. Especially for continuous ventilation, especially in basement rooms, it is sufficient if the window pane is only a crack wide

is tilted relative to the frame. This ensures adequate ventilation without unnecessarily increasing heating costs. Furthermore, with lower tilt positions, the penetration of vermin and small creatures, especially in basement rooms, is significantly reduced. Nevertheless, with a large opening angle of the window pane in the maximum tilt position, it is possible to ventilate the rooms quickly and briefly.

If the rod that forms the element of the locking device on the frame side is provided with an external thread that is screwed into a corresponding internal thread on the frame, the locking device can be removed from the frame in the simplest possible way. The window pane can then be easily removed from the tilt bearings and completely removed from the frame, for example for cleaning purposes. The detachable connection of the locking device to the frame also means that it can be easily replaced.

If the rod is divided into two sections by a joint, the locking device allows tilt positions with a large opening angle of the window pane. Furthermore, the free or outer section can then be swiveled out of the light entry opening into a position parallel to the upper frame section and fixed there in a holding device. As a result, the locking device is not visible from the outside when the window is closed. Furthermore, it does not impede the incidence of light or cause any disruption in the light entry opening.

To increase burglary protection, a grille bar is inserted through the frame across the light entry opening and secured with the help of

The security devices, in particular the split pins, are arranged on the outer perimeter of the window frame. Because the security devices, in particular the split pins, are arranged on the outer perimeter of the window frame, they are not accessible from the outside or the inside when the window is installed. A potential burglar can therefore neither loosen the security devices, in particular the split pins, nor pull the grille bar out of the window frame by force.

It is advantageous to attach a second grid bar to the frame, which crosses the first grid bar, in such a way that one grid bar passes through a hole in the other

This additionally secures the light entry opening and significantly increases the stability of a single grid bar against being pulled out by force.

If split pins are used to secure the bars, it is advantageous to embed them in grooves arranged on the outer circumference of the frame. The split pins or bars are thus easily held in position and do not protrude beyond the outer circumference of the frame.

Furthermore, the lattice bars can be surrounded in sections - between their intersection points or the intersection points and the frame - with pipe sections of the same outer diameter.

This gives the window an attractive appearance.

In addition, the pipe sections can completely conceal the bars and thus leave a potential burglar unsure about the nature of the bars.

Finally, rotating pipe sleeves can be arranged between the external pipe sections and the bars. The pipe sleeves, which can rotate freely on the bars, offer no resistance to a saw, so that sawing through the pipe sleeves would only be possible if the pipe sleeves covered by the pipe sections were held in place. This makes sawing through the bars virtually impossible.

The window shown in Fig. 1 has a window pane 11 made of multiple glass (here double glass). The window pane is formed in a manner known per se from two glass panes 50, 51 arranged parallel to one another and spaced apart. The spacing is ensured by a circumferential spacer 52. A cavity 53 is defined by the two glass panes 50, 51 and the circumferential spacer 52. The cavity 53 serves primarily for heat and sound insulation. However, a window pane made of single glass can also be provided.

To avoid injuries to or damage to the window pane, the window pane 11 can be enclosed in an edge protector not shown in Fig. 1. This edge protector can be designed all the way around or only cover the edges 17, 62, 63, 64 of the window pane 11 in certain areas, for example only in the corner areas. The edge protector will be discussed in more detail below.

The window pane 11 is located within a frame 13. The frame 13 comprises a lower section 16, an upper section 24 and side sections 25, 26 (Fig. 8), which are joined together to form a rectangle.

The frame 13 defines a light entry opening 12, which is covered by the window pane 11 in the closed position of the window pane 11 shown in Fig. 1. In the closed position, the window pane 11 rests against a circumferential seal 18. It prevents the ingress of drafts and vermin and also serves to insulate against sound. As can be seen in Fig. 1, the seal 18 is clipped into a corresponding groove in the frame 13 that is open towards the interior.

The structure of the window described so far can be used for very different embodiments of tilting or swiveling bearings of the window pane. Different locking or locking devices can also be provided, as will be described in more detail below. The embodiment shown in Fig. 1 is specifically a tilting window with tilting bearings 14 arranged in the lower area and a locking device 15 arranged in the upper area.

The tilting bearings 14 are each formed by associated angle plates 54 and stops 32. The angle plates 54 are arranged between the lower section 16 and the respective side sections 25 and 26 of the frame 13. The window pane 11 therefore lies with its lower edge 17 above

the angle plates 54 on the inside of the lower section 16 of the frame. In the closed position, it is held in contact with the circumferential seal 18 by the stops 32. In the open position, the stops 32 prevent the window pane 11 from slipping inwards. The stops 32, which can consist of plastic profile sections, for example, preferably have contact surfaces 48 on the side facing the window pane 11. The contact surfaces 48 are inclined in relation to the frame plane in such a way that the window pane in its maximum tilt position lies flat against the contact surfaces 48. As a result, a force acting on the window pane 11 from the outside is well absorbed by the stops 32. The tilt bearings 14 are also designed in such a way that the window pane can be easily removed upwards from the frame after the locking device 15 has been released.

The locking device 15 consists of a clamp 20 which grips the upper edge 62 of the window pane 11. The clamp 20 is fastened to the window pane 11 by suitable means, for example glued. At the end distal to the window pane 11, the clamp has legs 36, 37 which are arranged in an approximately V-shape relative to one another. For transport purposes, the clamp 20 can be dismantled into a section on the window pane side and a section comprising the legs 36, 37 or can be connected by means of screw connections, rivets, etc.

The clamp 20 is preferably made of metal, in particular spring steel. The legs 36, 37 each have a bore 22, 23. When the legs 36, 37 approach each other against the spring force of the clamp 20, the bores 22, 23 can be brought into such an aligned position that a rod 21, which corresponds approximately to the diameter of the respective bores 22, 23, can be pushed through them without constraint. The rod 21 has a threaded section at one end with which it can be screwed into a threaded sleeve 39 pressed into the frame 13. The rod 21 is preferably connected by a joint 33 to an inner frame 60.

Section 34 and a free, outer section 35. The free, outer section 35 has a right-angled extension 19, which can serve both as a handle and as a limiter.
5

When its legs 36, 37 on the rod 21 approach each other, the clamp 20 can be moved over the joint 33 until it rests against the extension 19. If the legs 36, 37 are not pressed against each other against their spring action, the clamp 20 spreads out on the rod. An axial displacement of the clamp 20 on the rod 21 is impossible in this case. The clamp 20 is fixed axially relative to the rod 21 by the edge of the holes 22 and 23.

This axial fixation is already surprisingly reliable if the rod 21 consists of a metal round rod. However, it can be further increased by providing corresponding notches or transverse grooves on the rod 21.

0 The locking device 15 described enables the window pane to be locked in any angular position up to a maximum tilt position. Furthermore, the window pane 11 can easily be removed from the inside of the frame 13, for example for cleaning purposes. To do this, the legs 36, 37 of the clamp 2 0 only have to be brought closer together and then the rod 21 must be unscrewed from the threaded sleeve 3 9 arranged on the frame. The window pane 11 can then be easily removed upwards from the tilt bearings. Opening the window or even removing the window pane 11 from the outside by a potential burglar is impossible both in the closed and in the open position of the tilt window.

In Fig. 2, an embodiment of an edge protector 65 already mentioned is shown. In the edge protector 65, an edge of a window pane 11 is enclosed in a corresponding recess 83 provided in the profile of the edge protector. The edge protector 11 has a U-profile section for this purpose. The recess 83 in which the window pane 11

is limited by legs 80, 82 of the U-profile section. On the inner surfaces of the legs 80, 82, nubs, barbs 85 or similar resilient elevations are preferably provided. They improve the adhesive properties between the window pane 11 and the edge protection 65. In addition, sealing and/or adhesive compound, such as silicone, can be accommodated in the remaining cavities between the barbs 85 and the window pane 11.

Furthermore, as shown in Fig. 3, a reducer 84 can be inserted into the recess 83 of the edge protection 65. By means of the reducer 84, the edge protection 65 intended for double glazing can also be used for single glazing with a correspondingly lower thickness. The reducer 84 has a recess 90 in an analogous manner for accommodating a window pane made of single glazing. Accordingly, barbs are also provided on the lateral boundary surfaces of the recess 90 on the reducer 84, which also improve the adhesive properties and provide space for sealing and adhesive compounds.

The edge protection 65 also has a continuous channel 72 extending along the profile. A round rod 76 (see Fig. 4) can be inserted into this channel 72. The round rod 76 can be used to stiffen the edge protection. " However, it can also be part of a swivel and/or tilting bearing, as will be explained using the schematic diagram in Fig. 4.

0 In Fig. 4, a part of a window pane 11 is shown which is surrounded by a peripheral edge protection 65. As already mentioned, a round rod 76 extends through the edge protection 65, which surrounds the edge of the window pane 11 associated with the lateral section 26 of the frame 13.

The round bar 76 protrudes with both ends laterally beyond the edge protection. The edge protection, which is assigned to an edge 17, 62, 63, 64 of the window pane 11, can either have a straight cut end or, as shown in Fig. 4, be mitred in such a way

16—

be cut so that an edge protection associated with the adjacent edge of the window pane 11 can be connected seamlessly over the corner. The ends of the round bar 76 projecting on both sides form bearing pins 66, 67, which can be received in corresponding pivot bearing bushes 68, 69 arranged on the frame 13. The round bar 76 and the pivot bearing bushes 68, 69 define an axis 70 about which the window pane can be pivoted within the frame 13.

Both the round rod 76 forming the bearing pins 66, 67 and the pivot bearing bushes 68, 69 are preferably made of metal. This results in a tilt and/or pivot bearing that can absorb high loads. Especially with a pivot window, the bearings must withstand high loads due to the leverage of an open window. Furthermore, it cannot be ruled out that, for example, a child holds on to the open window pane 11 surrounded by an edge protector 65. Such loads must also be absorbed by the bearings. Ultimately, the window cannot then be forcibly pushed out of the bearing from the outside.

The swivel or tilting bearing is particularly stable because the round rod 76 is continuous and

therefore, no unnecessary loads have to be absorbed by the window pane 11 or the edge protection 65. In this case in particular, the edge protection 65 can be made of elastic material, for example hard rubber (PVC, or the like). 30

However, if the edge protection 65 itself is made of a sufficiently stable material, for example hard PVC, it may not be necessary to form the round rod 76 continuously. The bearing pins 66, 67 can then also be formed by round rod sections, each of which can be inserted into the edge protection 65 at the front. The protruding ends then form the pivot bearing pins in an analogous manner.

Another possibility for tilting or pivoting the window pane 11 is to extend the edge protection 65 in such a way that the edge protection itself forms bearing pins 66', 67'. This variant is shown in Figs. 5, 6 and 7.

The bearing pins 66, 67' are formed in one piece with the edge protection 65. Corresponding pivot bearing bushes 68", 69 are provided on the frame 13. The front ends of the edge protection 65, formed as bearing pins 66", 67', can be received in the pivot bearing bushes 68', 69'.

A section through a pivot bearing bush 68' is shown in Fig. 6. The bearing pins ^66' , 67' have an approximately semi-cylindrical shape corresponding to the U-profile section of the edge protection 65. The pivot bearing bushes 68, 69 are hollow-cylindrical with a corresponding or slightly larger radius. An axis 70, about which the window pane can be tilted or pivoted, is defined by the center of curvature of the hollow-cylindrical bearing pins 66, 67'.

An opening 91 extending parallel to the pivot axis is provided on the outer surface of the hollow cylinder of the pivot bearing bushes 68, 69'. The opening 91 has at least a width that corresponds to the radius of the edge protection 65 or the bearing pins 66', 67'. If the opening 91 is directed upwards, for example as in the embodiment shown in Fig. 5, 6 and 7, the window pane 11 can only be removed from the bearing bushes and thus from the frame in a position tilted 90° out of the frame plane. The embodiment shown can be combined with any locking or locking device already described or to be described below. Removing the window pane from the outside is not possible and can only be done from the inside if the window pane 11 has been tilted into the corresponding angular position.

- 18 -

In this context, it is also conceivable to align the opening 91 in such a way that the window pane 11 can only be removed in a minimal tilt position, which just allows the window pane 11 to be removed past the upper section 24 of the frame 13.

The swivel or tilt bearing described with reference to Fig. 4 can also be developed into a combined swivel-tilt bearing. This is illustrated in Figs. 13a to 13c and 14a to 14d. In Figs. 13a to 13c and 14a to 14d only the diametrically arranged disengageable bearings of a swivel/tilt window are shown, to which reference is made below. The intermediate bearing consists of a swivel bearing pin, which can be formed in one piece with the lower end of the round rod 76. The lower end of the round rod 76 forming the swivel bearing pin can be rounded, for example hemispherical. However, an egg-shaped tapered end of the round rod 76 can also be considered. In any case, it must be ensured that the associated swivel bearing bush has a shape which allows the window to be swiveled and/or tilted into any desired position.

The second bearing required for the tilt function, which must be disengageable for the swivel function, is shown in Fig. ^13a to 13c. It comprises a swivel bearing bush 68" arranged in the lateral section 25 of the frame 13. If required, a pin 92 can be axially inserted into the swivel bearing bush 68", which forms a bearing pin 66" with its end facing the swivel bearing bush 68". The pin 92 is mounted in the previously described channel 72 of the edge protection 65 of the window pane 11 so that it can be moved longitudinally. It has a handle 93 protruding at a right angle. The handle 93 allows the pin 92 to be easily moved within the edge protection 65 and thus enables easy switching between the tilt and swivel functions. In addition, the handle 93 can be pivoted downwards together with the pin 92 after actuation and fixed in corresponding recesses on the edge protection 65. This enables axial fixing

of the pin 92 relative to the edge protection. An undesirable disengagement or engagement of the bearing pin 66" into the pivot bearing bush 68" is thereby avoided.

The diametrically opposite bearing, which allows a swivel function and must be disengageable in the tilting function, is described in Fig. 14a to 14d. A swivel bearing bush 69" is attached to the frame 13, here to the upper section 24 of the frame 13. The swivel bearing bush 69" is hollow-cylindrical or pot-shaped, whereby the

The outer surface has an opening 98 extending parallel to the pivot axis. On its side facing away from the frame, the pivot bearing bush 69" is open and has a collar-shaped edge 99. A pivot scissor 94 is rotatably mounted on the pivot bearing bush 69". The pivot scissor 94 has a longitudinal slot 97 which ends in a circular opening 96. For pivotable mounting, the pivot scissor 94 is pushed onto the pivot bearing bush 69" by means of the opening 96.

In the closed position or when the window is being pivoted, a bearing pin 69" arranged at the end of the round rod 76 described above is accommodated in the pivot bearing bush 67". The bearing pin 67" has a head disk 95 on its front end, which has a diameter that is slightly smaller than the inner diameter * of the pivot bearing bush 69". In the closed position or pivoting function, the bearing pin 67" with the head disk 95 is held in the pivot bearing bush 69" by the pivoting scissors 94 covering the opening 98 of the pivot bearing bush 69" with the edge of its opening 96 and preventing the bearing pin 67" from coming out of the pivot bearing bush 69". For this purpose, the pivoting scissors 94 (see Fig. 14b) is pivoted into a position parallel to the upper section 24 of the frame 13 (see Fig. 14a). If the window is to be brought into the tilt position, the bearing pin 66" already described with reference to Figs. 13a to 13c is engaged in the corresponding pivot bearing bush 68" on the frame and then the pivoting scissors 94 is moved from its position parallel to the upper section 24 of the frame.

pivoted by 90° towards the interior. The longitudinal slot 97 of the pivoting scissors 94 then extends approximately perpendicular to the plane defined by the frame 13. The slot 97 of the pivoting scissors 94 releases the opening 98 of the pivot bearing bush 99" and the bearing pin 67" can be transferred from the pivoting bearing bush 69" into the longitudinal slot 97 of the pivoting scissors 94. The maximum tilt position is determined by the length of the longitudinal slot 97.

The pivoting scissors 94 can also have a region (see Fig. 14b) which projects approximately perpendicularly to the longitudinal extension of the longitudinal slot 97 and serves as a handle. The tilting/pivoting device described above can be combined with a large number of features and devices which have already been described or are still to be described, for example with a locking device as explained with reference to Figs. 11a and 11b.

In Fig. 8, the window according to Fig. 1 is shown in a top view from the inside to the outside, but without a grille. Although in Fig. 8 the tilting bearing according to the first embodiment of the invention is formed by stops 32, as discussed with reference to Fig. 1, the bearing shown can be exchanged for any of the tilting and/or pivoting bearings described here.

Accordingly, the locking device 15 already described can also be applied to the other embodiments. As shown in Fig. 8, a holding device, in particular a blind hole 41, is provided in the upper section 24 of the frame 13, into which the free, outer section 35 of the rod 21 can be fixed with its extension 19 after pivoting in the joint 33 or in the threaded sleeve 39. As a result, the holding device 15 and in particular the rod 21 are not visible from the outside. The free, outer section 35 of the rod 21 is not located within the light entry opening 12. It therefore neither obscures the view outside nor does it prevent the light from entering in any way.

In Fig. 9, a holding device 15' is shown as an alternative embodiment to the holding device described so far

shown. Parts with the same function are given the same reference numerals. First, a clamp 20 is attached to the window pane 11 in an analogous manner, preferably glued to its upper edge 62. The clamp 20 can be dismantled into two parts for transport purposes and can also be put together by laymen using screws, rivets, etc. On the side distal to the window pane 11, the clamp has a guide element 28 through which a rod 21 extends. In this embodiment, too, the rod 21 is divided into a frame-side section 34 and an outer section 35 by a joint 33. The rod 21 can be attached to the frame 13 in an analogous manner to the holding device 15, namely screwed into a threaded sleeve 39. The frame-side section 34 of the rod 21 is designed as a round rod, as in the holding device 15. However, the free outer section 35 has a non-rotationally symmetrical, in particular square-shaped profile. The outer section 35 is guided through an opening in the guide element 28, which has a profile that is complementary to the outer section 35. As a result, the rod 21 cannot be rotated when the guide element 28 is located on the square profile of the outer section 35 of the rod 21. Only when the guide element 28 is pushed via the joint 33 onto the section 34 on the frame side, which is designed as a round rod, can the rod 31 be rotated and the locking device 15' released from the frame 13.

It is therefore impossible to unscrew the locking device 15· when the window is in the tilted position. The locking device can only be released when the window is in the closed position.

In a completely analogous manner, the holes 22 and 23 in the legs 36, 37 of the clamp 20 can also be replaced by square-shaped passages in the locking device 15 already described. The rod 21 is divided, as in the locking device 15', into a round rod-shaped frame-side section 34 and a profiled, in particular square-shaped section 35 by a joint 3 3.

In order to be able to lock the window pane in any angular position between a maximum tilt position and a closed position, the locking device 15' also has a clamping device 29 which, under spring load, axially fixes the rod within the guide element 28. Only when the clamping device 29 is actuated against the spring force is the axial fixation released and the guide element 28 can be moved axially on the rod 21. The maximum tilt position is limited by a hook-like extension 19, as with the locking device 15 according to Fig. 1.

In this embodiment of the locking device, a holding device can also be provided on the upper section 24 of the frame 13. However, this is not shown in Fig. 9.

Another embodiment of the tilting bearing is shown schematically in Fig. 10. The tilting bearing comprises two support bodies, of which only one support body 27 is shown in Fig. 4. This support body 27 is arranged near the lower section 16 on the side section 26 of the frame 13. For reasons of stability, it can also rest slightly on the lower section 16 of the frame 13. On the opposite side section of the frame 13, a support body is also arranged in a mirror image, which - however - is designed analogously to the support body 27. The support body 27 is arranged on a plate 58 attached to the side section 26 of the frame 13 so as to be rotatable in an axis parallel to the lower edge 17 of the window pane 11. The support body 27 has a seat at its end facing away from the lateral section 26 of the frame 13, into which the associated lower corner of the window pane can be inserted and held. The opposite support body (not shown) is, as already mentioned, constructed accordingly. The window pane 11 is thereby mounted so that it can be tilted in an axis parallel to the lower edge 17. An advantage of this mounting compared to that described in Fig. 1 is that the window pane 11 can be tilted even more easily between a closed and a tilted position.

When the locking device 15 or 15' is released, a tilt position of up to 90° relative to the frame plane can be achieved. It may therefore be sensible to fasten the window pane 11 to the seat 59 of the support body 27, preferably by gluing it. It is then of course no longer possible to remove the window pane 11 without further ado. Nevertheless, the outer surface of the window pane 11 can be cleaned in the 90° tilt position already described.

In Fig. 11a and Fig. 11b an embodiment of a window locking device 61 is shown. The

■"VI locking device 61 fixes the window pane in a closed position relative to the frame 13. In an open position, the window pane 11 cannot generally be locked in a specific angular position, unlike with the locking device 15 or 15·. Therefore, the locking device 61 is primarily intended for a pivot window or tilt/pivot window. In principle, the locking device 61 can also be combined with a tilt window, in which case, however, a maximum tilt position should be ensured by other suitable means.

The locking device 61- ~ shown in Fig. 11a and 11b comprises a plate 86 which, as shown in Fig. 11b, is fastened to the edge protector 65, preferably screwed on. For this purpose, the edge protector 65 can also have a screw channel 71 which is arranged between the recess 83 and the channel 72 and extends along the channel 72. The plate 86 is then screwed to the edge protector 65 by means of two screws without pre-drilling holes. The plate 86 is approximately wedge-shaped in side view and has a flat surface on the side facing away from the edge protector 65, while the side facing the edge protector 65 has the curved surface corresponding to the profile of the same. The plate 86 can also be glued to the edge protector 65. On the plate 8 6, an angle lever with an elongated window handle 87 is pivotally mounted such that the handle in

a plane approximately parallel to the window plane. On the side opposite the window handle 87 relative to the pivot bushing, the lever has a double locking lug 88 which, in the closed position, engages in a corresponding profile of the frame 13, which can be formed by grooves 89.

If the window handle 87 is pivoted out of the window closed position shown in Fig. 11, the locking lug 88 disengages from the frame 13 and the window pane 11 can be pivoted or tilted out of the frame 13.

The double locking lug 88 provides a two-stage locking mechanism. The locking device 61 allows the window pane 11 to be locked in the closed position against the circumferential seal 18. In addition, the window pane 11 can be locked in a second position with the double locking lug 88 open a gap.

The edge protection 65 is therefore also ideally suited for attaching a locking mechanism. In the same way, however, the actual locking mechanism could also be attached to the frame 13 in a rotatable manner and only a fitting could be provided on the edge protection 65. In the closed position ■*, the locking mechanism could then be in engagement with the fitting of the edge protection. When the locking mechanism is pivoted, the fitting arranged on the edge protection 65 could be released and the window pane 11 held in the edge protection 65 could be pivoted relative to the frame 13.

Fig. 12 shows an embodiment of the window according to a further aspect of the invention. All of the components of a frameless pivoting or tilting window described so far are also designed to provide sufficient resistance to violent influences, for example by burglars.

Nevertheless, it is advantageous to lead at least one grid bar 30 across the light entry opening 12 through the part of the frame 13 that protrudes outwards over the window pane 11 and to secure it by means of a split pin 43 arranged on the outer circumference of the frame 13, i.e. only accessible from the wall side. The split pin is led through a transverse hole in the grid bar 30 in a manner known per se. Alternatively, a spring ring could also be pushed into a groove running around the grid bar or into a corresponding notch.

Alternatively, the grid bar 30 could be replaced by a

The split pin can be secured by a split pin located inside the frame 13 and insertable from the interior. The split pin could, for example, protrude from the stops 3 2 on the interior side with an angled end section, a ring arranged on the split pin or the like, preferably in such a way that the split pin is not visible from the outside.

The lattice bar 30 can either be guided in through holes on both sides in the frame 13 and protrude at both ends on the outer circumference of the frame 13, or it can, as shown in Fig. 1, be received with one end, here its lower end, in a blind hole 55 and with its other end be guided through a through hole 56 and protrude beyond the outer circumference of the frame 13. The split pin 43, which secures the lattice bar 30 at its upper end, is preferably embedded in an outer circumferential groove 57 of the frame.

In the embodiment shown in Fig. 12, two bars 30, 31 cover the light entry opening 12. The bars 30, 31 are located in front of the window pane 11 when viewed from the outside. They cross approximately in the middle of the light entry opening 12, whereby the bar 31 has a smaller outside diameter than the bar 30 and is guided through the bar 30 in a hole 42. The bars 30 can be made of solid material or can be designed as tubes. As in Fig. 1, the bar 30 is secured only at its upper end with a split pin 43 indicated by dashed lines. The

Lattice bar 31, on the other hand, is secured at both ends by split pins 44, 45 shown in dashed lines. The split pins 43, 44, 45 are only accessible from the outer circumference of the frame 13. As soon as the window is inserted into a corresponding wall opening, the split pins 43, 44, 45 are no longer accessible and the lattice bars 30, 31 can neither be pushed out nor pulled out.

Pipe sections (not shown) can be pushed over the sections of the grid bars 30, 31 shown in Fig. 12. Furthermore, pipe sleeves 46, 47 that can rotate freely on the grid bars (in % Fig. 3 only on the grid bar 31) can be arranged between the pipe sections and the grid bars. When attempting to saw through the grid bars, it would be possible to saw into the outer pipe section (not shown) until the saw hits the pipe sleeve underneath; then, however, the pipe sleeve underneath would rotate freely on the grid bar in line with the sawing movement and prevent the saw from penetrating further. The saw could only cut through the pipe sleeve 46 or 47 if the pipe sleeve was prevented from rotating freely on the grid bar. To avoid this, the pipe sections (not shown) are mounted on spacer bushings on the frame side in order to avoid creating a connection to the internal, rolling pipe sleeve 46 or 47 in the area of the frame 13. The grid bars can be, for example, galvanized solid steel bars, the pipe sleeves 46, 47 plastic pipes and the pipe sections (not shown) stainless steel pipes.

Of course, additional bars can be passed across the light entry opening 12 through the frame 13. Furthermore, the arrangement of bars 30, 31 secured by split pins 43, 44, 45 is in no way limited to the geometry of the frame 13 shown here and/or the arrangement of bars 30, 31 relative to one another or to the frame 13. The bars 30, 31 can be arranged at any angle relative to one another or to the frame 13. The frame does not necessarily have to have an exactly rectangular shape either.

All features disclosed in the application documents are claimed as essential to the invention insofar as they are new compared to the prior art, either individually or in combination.
