DK 155057 B

The present invention relates to a window or door frame with releasably attached, non-slip bars and of the kind specified in the preamble of claim 1.

In recent years, they have switched to supplying window-5 leaves or glass door blades with only a single glass pane, regardless of the frame size. because of the simpler insertion and the shorter sealing lengths, since such panes are no longer as previously fastened in the frames, but are enclosed in lip seals.

Now, for architectural reasons 10, on the other hand, it is often undesirable with such large glass surfaces, which is why they divide such frames by means of so-called false bars, which are applied on the outside and possibly on the inside of that leaf on the glass pane.

The known buckles have in their interior a longitudinally lockable locking bolt 15, which can usually be brought out and retracted by means of an operating element located on the outside of the buckle (eg European patent application no.

00 09 242). Such false bars have the advantage that they can be removed at any time to simplify to some extent the cleaning of the window pane below.

Particularly large glass surfaces, due to wind pressure, carry out considerable vaults, where it is preferable not to place the diffusers immediately on the glass pane, but at some distance from it. These precautions also have the advantage that rainwater 25 and the like, which are usually contaminated by flue gases, can more easily run down from the pane and not accumulate in the corners between the diffusers and the heat, where after evaporation it leaves dirt residues.

A disadvantage of such false spreader lies in that the control member for the fastening is visible from the outside. It is thus immediately possible to recognize that this is not in fact real, but rather genuine spruces.

This disadvantage is remedied by the known window frames (German usage pattern no. 73 14 173), which form the starting point 35 of the invention in that a ball snap lock is inserted at the end of the groove, the locking ball of which can jump into a recess formed in the corresponding surface in the window frame.

However, one disadvantage of such a locking device is that in order to ensure a convenient insertion it can only compensate for small length changes seen in the longitudinal direction 2

DK 155057 B

of that proverb. For example, deformed. the frame due to unilateral heating, e.g. due to solar radiation, feather-; For example, the opposing frame strips are, under certain circumstances, so far apart that the ball-shaped locking device is no longer able to compensate for this length change, and in this case the jaws loosen. Furthermore, the necessary force for impression and expression is! in resolving a known locking device to a great extent depending on the distance between the locking device and the locking gait, so that even when no deformations occur in the frame, extremely precise compliance with the design dimensions is necessary to ensure that the clamps remain in place during use. in that framework, and partly that it can be triggered without delay. For the release of the scraper, no lifting tool can be used, as this must be supported against the fragile glass pane.

In accordance with the described technique, the invention provides a window or door leaf by which the spurious bars can be placed and released invisibly from the outside, allowing large tolerances in the dimensions of the bars and frames, where only a relatively low force is required without affecting the secure retention of the clamp.

Furthermore, the invention provides a single interconnection of the interconnectors at their intersection sites.

The invention also provides a very economical window or door frame, in the manufacture of which elements not yet adapted to the invention can be used with only minor changes.

According to the invention, this is achieved by the properties specified in the characterizing part of claim 1.

According to the invention, in contrast to other false spacer arrangements, the protruding element is not placed on the spacer but on the transverse surface to which the spacer is to be attached. For its part, the chute has a downwardly open locking clamp which can be pressed down over the corresponding tab in a simple manner.

During use, the pin can perform axial movements relative to the locking buckle without affecting the connection between the locking buckle and pin.

DK 155057 B

Since the retention between the locking clamp and the pin does not depend on their mutual position in the longitudinal direction of the clamp, it is always possible to apply and remove the clamp with the same force.

The chute only has a recess on the underside, through which the pin can pass through when the chute is applied or removed. The upper side of the chute thus remains untouched, so that the window or door frame according to the invention does not recognize from the outside that it is a real chute.

10 Instead of a single tap, there may also be several tabs side by side at each sprocket sight.

As only a single pin is present, according to an advantageous embodiment according to the invention, it is advantageous that it is placed centrally with respect to the hollow profile which constitutes the groove.

The pin may have a club-like thickening at its free end, whereby the locking device can only follow the length change of the chute only to a limited extent, so that longitudinal changes can only be offset when a corresponding mutual displacement is provided. However, according to a design according to the invention, it is an advantage that the pin is cylindrical in such a way that longitudinal alignment between grooves and frame strip can be made by displacement between pin and locking device.

In principle, it is possible to use a flat profile as a pin, which has the advantage that it is secured against this clamp at the same time against tilting movements. However, according to a design according to the invention, it is advantageous to use circular cylindrical pins, since in some cases their manufacture and arrangement are simpler, and the orientation does not have to be taken into account in their placement.

In principle, it is possible to screw the pins, weld them on or, possibly by pressure-molded frames, even to cast them.

However, in accordance with an embodiment of the invention, it is advantageous to insert the pins in a bore, this feature enabling the particularly simple, possibly also later, placement of false bars. As a pin, a hollow pin is preferred, which is optionally adapted so as to

4 DK 155057 B

! wall thickness that a reliably clamping fit is easily obtained after inserting the pin into the bore. j

The pin or hollow pin may be formed of any suitable material. Since it is only subjected to small cut-off forces during use, the use of plastic material is particularly preferred. This feature also facilitates a later bore of the pin, which may be desirable when, as a result of an architectural change, the clamps have to be waived. In this case, it is sufficient, if possible, with an inserted glass pane to drill out the pin and replace it with a flushing flap. Below, the use of a hollow pin due to the possible centering of the drill is particularly advantageous.

There are various ways of interconnecting the claws. According to a preferred embodiment 15 according to the invention, a groove having two transverse surfaces, up to which adjacent clusters abut, is provided with a through-hole in which a single pin is pierced, the length of which is such that appearing on both sides.The required length that a tap should have.

Such a through pin is not only a particularly simple and thus economical connection at a junction site of the thrusters, but the through pin advantageously transfers forces from one cross-thrust to the other, so that the profile of the thrust carrying the pin only is relatively slightly loaded.

According to another embodiment of the invention, the transverse surface slopes with respect to the longitudinal axis of the chute, the corresponding surface on the end of the chute having a complementary slope. By these features, the bar is prevented from rotating about its longitudinal axis, even when the bar is advantageously a certain distance between its underside and the adjacent surface of the pane and when using circular cylindrical pins.

The recess located in the underside of the chute allowing the insertion of the pin may be configured as a correspondingly accurate milling. However, according to another embodiment of the invention, on the end abutting against the transverse surface, there is a simple bevel to form the recess. Thus, the recess needed at the end of the chute can be done simultaneously with the truncation of 5

DK 155057 B

the cutter from the hollow profile rod using a saw template. The bevel also provides space for the lip seal located at the transverse surface, which can extend from the impact site between the transverse surface and the pane along the latter.

5 The locking clamp can e.g. consist of one to two clamping boxes made of leaf leaf strip which is welded or riveted to a metal core in the profile rod. However, according to yet another embodiment of the invention, the clamping trays are disposed at the end of a support member axially inserted in the hollow profile of the groove at a location near the upper side of the groove and extending therefrom across the groove towards the underside thereof. Thus, it is possible to form a standard insertable part which is simply insertable into the hollow profile rod, which constitutes the locking device, so that, especially at a later application of the struts, it is only necessary to cut these 15 from a profile rod. The standard part then simply needs to be inserted, after which the sprayer is ready for application.

Should a sheave be broken off at a clamping tray, you simply need to insert a new standard part and the sheave can be used again.

20 In order to prevent the insertable locking device from slipping too far into the ratchet end, it has a stop. This abutment according to an advantageous design according to the invention may be formed by at least one of the clamping jaws being extended downwards with an abutment extension so that it abuts the wall forming the underside of the barrel where the chamfering ends. This abutment attachment does not extend or slightly beyond the outer contour of the chassis so that it does not prevent the attachment of the chute even close to the glass pane.

Furthermore, this impact facilitates handling when the locking device has to be removed from the chute in case this is necessary due to a damage.

Furthermore, the impact extension may be so designed that it slides as a guide along the pin before sliding into the clamping tray so as to simplify insertion of the clamp.

According to yet another embodiment of the invention, the clamping trays are bevelled downwards and outwards, so that when the clamp is pressed against the pins, they are pressed apart by a relatively small force. Further, these chamferings have a single 4- VA Λλ tTI V * 1 / · V \ 4 Μ / "T ΛλΊΛ 1 Λ V * V * SM" VS 4— M 4 ^ -P Λ · η «νΜι" Λ Γ * Λ 6

DK 155057 B

The force required to remove a splinter is in addition to the choice of material for clamping trays and pins depending on the spring properties of the disc as well as the opening width between the two trays. j

When controlling these three parameters, the power required to trigger a 5-sprocket can be set within narrow limits corresponding to the requirements encountered. j

In principle, it is possible to design the external cross-section of the carrier with great accuracy, corresponding to the internal cross-section of the hollow profile rod used, so that due to their mutual design, a sufficiently tight fit of the carrier in the groove is ensured.

However, according to an embodiment of the invention, the outer profile of the carrier and the internal profile of the groove are so aligned that the carrier can only be inserted in the lateral direction substantially without clearance. In order to also achieve a guide without clearance there in a direction perpendicular thereto, according to the invention, a tensioning tongue is arranged which is resilient and is pressed against it by the introduction of the support means thereby ensuring that the supporting means 20 is constantly pressed against one of the side of the sprayer. This side is preferably the upper side, thereby obtaining the additional advantage that when the pane is pressed against the bar due to a high wind pressure due to a high wind pressure, the bar can be displaced outwards under the spring action from the tension tongue without affecting the restraint between the clamping trays and the pins. .

Preferably, the groove has an outwardly tapered interior profile in the form of a straight-legged trapezoid, while the carrier has a rectangular exterior profile, the longest side of which is slightly shorter than the shorter of the two parallel sides of the staircase. Hereby, when cleaning a pane, the sprayer can be turned without loosening it in the lock, since the rectangular profile of the support allows a certain twist of the trapezoid profile.

At the end of the twist, the resilient clamping tongue automatically pushes the clamp back into the correct position, in which the supporting means and cleats lie flat against each other.

As already mentioned, in the connection according to the invention between the ridge and the transverse surface, considerable distances between the end of the ridge and the corresponding transverse surface can even be offset. If such a distance is now set, it is conceivable that the locking device shifts out of the chute and up onto the pin.

DK 155057 B

In order to prevent the pin in this case from penetrating too deeply into the carrier and then affecting the removal of the chuck, according to an embodiment according to the invention on the carrier on the side facing away from the pin, a stop adapted for abutment may be provided. against the pin.

It is preferred that the locking member is injection molded in one piece of plastic material, thereby ensuring a particularly simple and cost-effective manufacture with sufficient target accuracy. Further, a resin may be selected which, in combination with the material used for the pins, still ensures compliance with the necessary mutual friction conditions so that the fit of the clamping trays on the pin takes place due to the shape and spring performance of the clamping trays and not due to the friction.

The object of the invention will now be described in more detail with reference to the drawing, in which:

FIG. 1 is a plan view of a window frame according to the invention; FIG. 2 shows a section through a frame strip along the line X1-X X, FIG. 3 shows a section along a frame strip along line III-III; and FIG. 4 shows a locking device made in one enlarged perspective view.

In FIG. 1, there is shown a window frame 1, which is divided by means of a longitudinal groove, and two transverse grooves extending perpendicularly thereto, of which only one is shown.

All bars 2,3 abut their two ends bluntly against a transverse surface 11 of the window frame 1 or against the longitudinal bar 2.

At each point where a cross-cutter is omitted, pins 4 are visible on two opposite cross-faces, which are placed opposite one another on the center axis of the cross-cutter 3 not shown.

The pins 4 are fixed in the window frame 1 and in the longitudinal groove 2, and are formed as cylindrical pins with a diameter of approx. 8 mm and they appear approx. 6 cm from the corresponding surface 11.

In FIG. 2 shows a section along line II-II according to i

8 DK 155057B

FIG. 1. This section shows a location of a transverse groove 3, which, however, is omitted in the illustration. j In FIG. 3, on the other hand, is shown to be fitted with a cross-brace 3. i

As shown in FIG. 2 and 3, the window frame 1 is formed of a plastic hollow profile having a groove for receiving a rubber lip seal 5, which sealingly abuts against a glass pane 6 inserted in the frame.

The retaining means and stops for the pane 6 have been omitted for the sake of clarity.

10 When using plastic material and by placing hollow space in the hollow profile rod 1, it is ensured that only a small heat transfer occurs between the outside and the inside of the frame.

A hollow pin 4 is inserted in the walls of the window frame 1 facing the glass pane 6, the axis of which extends parallel to the frame surface and with the glass pane 6. The protruding free end of this hollow pin 4 forms a pin for engaging the FIG. 4.

The transverse surface 11, from which the pin 4 protrudes, does not stand perpendicular to it, but slopes slightly as shown in FIG. 2nd

In FIG. 3 it is seen that in the window frame 1 a bore 7 is arranged into which the hollow pin 4 is inserted.

The hollow pin 4 is made of the same profile material as the rain drain pipes inserted on other sides of the window frame. The use of a relatively thin-walled hollow rod thereby not only ensures that, upon insertion into a barely metered bore 7, it yields sufficiently so that the adjacent outer surface of the window frame 1 does not vault outwardly, but such a hollow pin also prevents the formation of a cold bridge in vinduesrammeprofilet. Finally, such a hollow pin also allows for a particularly light drilling if, as a result of a change in the architectural taste, it will later be relinquished to the springs 2,3.

In FIG. 3, the applied cross-member is shown, extending coaxially with respect to the hollow pin 4.

The cross bar has a metal profile 8, which at its outer surfaces is surrounded by a plastic sheath 9.

The end surface 12 facing the transverse surface 11 of the transverse cutter 3 is cut in the upper half obliquely complementary to the transverse surface 11 in such a way that a plane 9 can be obtained.

DK 155057 B

plant.

The lower part of the cross bar 3 abutting against the glass pane 6 is provided with a bevel 13, the main purpose of which will be described later. This bevel 13 provides a space between the 5 cross bar 3 and the window frame 1 in which the outer lip of the lip seal 5 can fit.

It is seen that a small distance is maintained between the glass pane 6 and the underside of the transverse bar 3 allowing a deformation of the glass pane 6.

10 In the free trapezoidal inner cross-section of the crossbars 3, a locking member 10 is inserted, which is shown in greater detail in FIG. 4th

This locking member 10 has a quadrangular support member 15, on the front and top surface of which is formed a prominent 15. On both sides of this list are arranged downwardly clamping trays 14 which have on their faces facing each other a circle profile corresponding to the exterior profile of the hollow pin 4.

The clamping trays 14 have outer surfaces which, together with the side surfaces and the upper surface of the carrier, lie in a common plane. On the side facing the window frame 1, the two clamping trays 14 form a common surface extending across the hollow pin 4.

Between clamping trays and supporting means 15, a cross-slit 18 is formed.

On the transverse edge facing the transverse slit 18, a resilient tensioning tongue 16 is formed which extends downwards from the anterior lower edge of the supporting member in unstressed condition (Fig. 4) and is thereby easily bent from the lower surface of the supporting member. 15th

The lower surface of the clamping tongue 16 has a surface which extends approximately parallel to the clamping tongue, and a surface extending in relation to this inclined and towards the tapered end.

The latter face serves as a guide when inserting the locking member 10 into the interior of the cross member 3, while its first face is inserted by inserted locking member 10 and with the tensioning member 15 pressed substantially substantially parallel to the lower planar face of the interior. profile of the cross cutter 3.

As shown in FIG. 3, the carrier is hollow, the cavity formed having a smaller height than the diameter of the hollow pin 4, so that its end is positioned adjacent an edge 19 which forms a stop which prevents the protruding end of the hollow pin 4 from being inserted into the the interior of the carrier 15.

The downwardly directed ends of the clamping trays 14 are bevelled outwards to facilitate the application of the hollow pin 4 and the ends are provided with two abutment extensions 17 extending so far as to abut the lower wall of the cross-brace 3 at the lower outlet of the chamfer 13, but does not appear in relation to the outer contour of the chamfer 3.

The edges of the abutment projections 17 (abutment edges) facing the cross-cutter 3 align with the back wall of the clamping jaws 14 at the slot 18.

15 From these abutment edges, the abutment perforations 17 in the axial direction of the hollow pin 4 have a substantially smaller depth than the clamping trays 14. This is achieved as shown in FIG. 3, the rubber lip seals 5 remain unchanged.

When inserting clamps in the window frame 1, the latter is first provided with the necessary bores 7. The longitudinal ridge 2 is provided with a through-bore (not shown) corresponding to the bore 7. Then holes 4 are inserted into the bores in such a way that they appear from the transverse surfaces 11 concerned in such a way that with the locking means they do not precisely reach the abutment edges of the extensions 17.

Next, the locking means 10 are inserted into the lugs 2,3, the ends of which are already provided with the end faces 12 and the chamfer 13.

The push-in of the locking means 10 is continued until the stop 17 extends 17 against the wall of the springs.

Hereby the clamping tongue 16 presses the upper surface of the support member 15 which aligns with the upper surface of the clamping jaws 14 against the corresponding internal surface of the clamp 3, so that the axis of the recess formed by the clamping jaws 14 is in a fixed position. which by inserting spool 2,3 coincides with the axis of the corresponding hole pin 4.

In addition, the longitudinal groove 2 is first applied in such a way that the protruding ends of the hollow pins 4 are placed between the abutments 17, which serve as

DK 155057 B

in guides. Then, the longitudinal groove 2 is pressed in a direction towards the glass pane 6. This causes the hollow pins 4 to run up against the bevels on the underside of the clamping trays, pushing them apart and sliding between them, whereby the clamping trays 14 spring back into their starting position. The transverse diffusers 3 are then placed in an analogous manner.

To remove a spanner 2.3, simply pull it away from the window frame 1 in the opposite direction.

As shown in FIG. 4, the locking member 10 forms a one-piece integral building element 10 which is injection molded with resilient plastic material. The latches 2,3 are formed in a common profile material, so that for the inclusion of the shown window frame in a manufacturing program only the manufacture of the locking means 10 is necessary.
