Abstract

The method involves cutting a set of bars into a miter at two ends, where the set of bars are made of plastic. A fitting groove (4) is provided in the bars, where the fitting groove retains a lock bar. The lock bar is inserted into the fitting groove according to the length via a front side opening of the bars, where the lock bar is used as shielding rail. The cut bars are assembled at joint to a leaf, and the assembled bars are connected with each other. A transmission is connected to the locking bar. An independent claim is also included for a plastic window and/or door.

Description

The present invention relates to a plastic window or a plastic door with at least two miter-cut spars, which are assembled to produce a connecting corner butt to joint and interconnected, wherein in the connecting corner forming spars each a fitting groove is formed, the two on opposite side walls of the Tray formed, inwardly projecting wall sections comprises, at least one locking bar is slidably mounted in at least one of the fitting grooves and the locking bar is at least partially disposed under the two inwardly projecting wall sections of the fitting, so that leakage of the locking bar from the fitting groove in a direction transverse to Longitudinal extension of the fitting groove is prevented. Furthermore, the invention is directed to a method for producing plastic windows or doors.

Plastic windows or doors of the type mentioned are usually made by first cutting the individual longitudinal and transverse bars of the frame miter, then the trimmed bars are struck together in bursts, whereupon the adjoining bars are connected to each other, for example by a welding process , The welding process comprises a rest phase following the actual welding operation during which the plastic material has to cool down. During this resting phase (cooling phase) is an undesirable dead time, since the person performing the assembly and welding of the individual spars during the resting phase no further Manufacturing steps on the frame can perform and thus the idle phase must wait idly.

Only after the end of the idle phase, which, for example, lasts approximately 1 minute together with the welding operation, in a subsequent method step, the gearbox together with the cuff rails and locking bars fastened thereto are inserted from above into the fitting groove, ie in a direction perpendicular to its longitudinal extent , Then the cuff rails to cover the fitting groove are fixed with screws on the frame. The screws extend through slots in the slidably mounted on the cuff rails locking bars.

In addition to the dead time described is disadvantageous in this production that in addition to the locking bars cuff rails are required and their attachment by screwing requires an additional step.

It is also possible to use instead of the locking bars to be used from above in the fitting groove and the additional cuff rails, which are inserted after assembly and welding of the individual spars of the connecting corner in the longitudinal direction in the fitting groove. Since the inwardly projecting wall sections prevent such insertion in the region of the connecting corner, it is necessary to cut off the inwardly projecting wall sections in the region of the connecting corner after assembly of the individual spars, so that an insertion possibility for the locking bar is created in the region of the connecting corner ,

A disadvantage of this variant, in addition to the also existing dead time, that the locking bars on the connecting corners of the fitting groove can also emerge completely again, as long as they are not otherwise secured in the fitting. In addition, the obliquely cut wall sections deteriorate the visual appearance of the windows or doors.

It is an object of the present invention to provide a method for producing plastic windows or doors that is inexpensive to carry out. Corresponding plastic windows or doors should be inexpensive and easy to produce.

According to the invention this object is achieved by a method for producing plastic windows or doors, in which a plurality of at least partially made of plastic spars are mitred respectively at its two ends in a first method step, wherein at least in a spar formed for receiving a locking bar Beschaltungsut is provided in a subsequent process step, the locking bar is inserted over a frontal opening of the spar in the fitting groove lengthwise, in a subsequent process step, the trimmed spars are assembled butt to thrust to form a wing and in a subsequent process step the composite spars are interconnected.

An inventive plastic window or a plastic door of the type mentioned above is characterized in that each formed on the same side of the fitting grooves on the side walls of the fitting, inwardly projecting wall portions adjacent to each other at the connection corner and thereby each a closed form around the connecting corner running around, inwardly projecting total wall portion.

According to the invention thus the locking bars are not used for the first time after assembly and connecting the individual spars in the finished sash, but the locking bars are already used in the fitting, while the spars are still separated. In this state, the fitting grooves are still formed open on the frontal, mitered ends of the spars, so that at both ends of the spar end-side openings are formed, in which the locking bars can be inserted lengthwise. According to the invention, the insertion of the locking bars in the fitting groove can take place while the previously processed frame is in its quiescent phase (cooling phase). In this way it is achieved that this resting phase means no dead time for the mechanic, but that during this rest phase already preparatory actions for the production of the next frame, namely the insertion of the locking bars in the still loose individual spars, are performed.

If the resting phase of the frame produced first completed, the finished frame connected to a unit can be removed from the welding device and it can be already pre-equipped with the locking bars single struts of the frame to be subsequently produced inserted into the welding device. The dead time described above can be prevented in this way and the profitability of the production can be increased.

In addition, in the production according to the invention, a cutting off of the inwardly projecting wall sections for the insertion of the locking bars is no longer necessary since the locking bars become welded after welding the single spars are already in the fittings. Thus, this required in the prior art additional operation can also be omitted. In other words, after the assembly of the individual spars inwardly projecting wall sections in the connection area must not be cut off obliquely to create an insertion possibility for the locking bar in the region of the connecting corner. A shaping of the spars is completed with the joining. After the connection of the spars thus a final contour of the wing is created substantially.

Finally, the locking bars are also automatically secured in the fitting groove, since a limit for the locking bars is formed due to the adjacent in the region of the connection corner and closed around the connection corner running inwardly projecting total wall sections, prevents the complete emergence of the locking bars from the fitting becomes.

According to an advantageous embodiment of the method according to the invention, a transmission is used in a direction transverse to the locking bar in the fitting groove and connected to the locking bar in a further subsequent step. The connection can be made via a conventional connection, for example, a toothing. By such a toothing, which may be in the form of a so-called "rack" cooperating with a rack, for example, an adjustment of the effective length of the locking bar is possible. In principle, it is also conceivable to use the gearbox already directly after the insertion of the locking bars and only then to connect the individual struts. However, then the device for connecting the individual spars must be designed according to also accommodate the geared spar and edit.

According to a further preferred embodiment of the invention, the locking bar is at least partially inserted under two formed on opposite side walls of the fitting groove, inwardly projecting wall portions of the fitting groove, so that leakage of the locking bar from the fitting groove in a direction transverse to the longitudinal extent of the fitting is prevented. Thus, according to the invention the locking bar engages under the inwardly projecting wall sections, in particular with its two lateral longitudinal edges. Preferably, in each case a longitudinal groove may be formed on the lateral longitudinal edges of the locking bar, in which engage the inwardly projecting wall sections. Advantageously, the locking bar has at least partially an H-shaped cross section. It is also possible that the locking bar is formed flat-rod-shaped and is guided between said, inwardly projecting wall sections and further, closer to the groove bottom, inwardly projecting wall sections. A guide between the inwardly projecting wall sections and the groove bottom itself is basically possible.

By the under or behind reaching it is achieved that the locking bar is automatically secured in a direction perpendicular to the longitudinal extent of the fitting groove and not by additional elements, such as a faceplate or additional fasteners against leakage from the fitting groove must be secured. Since in the longitudinal direction of the fitting groove also a complete leakage of the locking bar is prevented by the abutting at the connecting corner inwardly projecting wall sections, thus securing the locking bar is realized in a very simple and cost-effective manner.

Preferably, the composite spars are welded together. In principle, however, another type of connection, for example gluing, is possible.

It may be provided that a locking bar is used with at least partially H-shaped cross-section.

According to a further advantageous embodiment of the invention, the locking bar comprises at least one bar exclusion and / or a locking pin and / or a corner deflection. This ensures that after insertion of the locking bar and assembly of the individual spars and insertion of the gearbox a fully functional frame with fitting arrangement is created.

According to a further preferred embodiment of the invention, several, in particular all spars comprise a fitting groove, locking bars being inserted into a plurality of, in particular, all fitting grooves. This is particularly useful when using the method according to the invention rotary / tilting vanes or wings to be produced with additional locks on the upper and / or lower cross member and / or on the belt-side rail. The locking bars, which are already inserted into the fitting grooves in this case before the individual spars are put together, can then be joined after connecting the spars, e.g. be subsequently connected by externally patch Eckumlenkungen.

Preferably, the width of the rod exclusion is smaller than the clear width between the inwardly projecting wall sections. This ensures that the bar exclusion despite the closed running around the connection corner, inwardly projecting total wall sections from the fitting groove is extendable to fulfill its locking function.

It may be provided a transmission which is connected for displacing the locking bar with this.

Further advantageous embodiments of the invention are specified in the subclaims.

Fig. 1 shows a partial perspective view of a window frame 1, which was not made according to the invention. The window frame 1 comprises two spars 2 which have been cut to a miter and assembled to produce a connecting corner 3 butt to joint and then welded together in a conventional manner.

In the forend of the spars 2 each have a fitting groove 4, 5 is formed on the side walls 6, 7 each formed as elongated lugs, inwardly into the fitting grooves 4, 5 projecting wall sections 8, 9, 10 are formed. A corresponding inwardly projecting wall portion is also formed on the side wall 7 of the fitting groove 4, due to the perspective view in FIG Fig. 1 but not visible.

In the fitting groove 4, a locking bar 11 is slidably disposed, on whose longitudinal sides 12, 13 longitudinal grooves 14, 15 are formed, projecting into the projecting wall portion 8 and the not shown, inwardly projecting wall portion, thereby forming a guide for the locking bar 11 becomes.

In order to introduce the locking bar 11 after welding the spars 2 in the fitting groove 4, the inwardly projecting wall sections 8, 9, 10 and not shown inwardly projecting wall portion are cut obliquely in the region of the connecting corner 3, whereby an insertion opening 16 for the Lock bar 11 is formed. However, you can through the insertion opening 16, the locking bar 11 also completely emerge again, so that the locking bar 11 is thus not mounted captive. In addition, the production of the window frame 1 is time-consuming, since after welding the two spars 2 first a cooling phase must be awaited before the inwardly projecting wall sections 8, 9, 10 can be cut off obliquely and the locking bar 11 are inserted into the fitting groove 4 can.

The manufacture and construction of a plastic window designed according to the invention or a plastic door designed according to the invention are described on the basis of FIG Fig. 2 to 10 explained in more detail below using the example of a plastic window.

The Fig. 2 to 4 show a spar 17, which is equipped with two locking bars 18, before the spar 17 with further bars 19 (see Fig. 6 ) is connected. The spar 17 comprises an elongated fitting groove 20, which is open towards the forend of the spar 17 and opens at the two mitred ends 21 of the spar 17 in frontal openings 22.

The locking bars 18 are inserted over the frontal openings 22 in the fitting groove 20 in length until they have their in Fig. 4 reach shown positions.

As in particular from Fig. 5 can be seen form on side walls 23, 24 of the fitting groove 20 formed, inwardly into the fitting groove 20 projecting wall sections 25, 26 guides for the locking bars 18. These each have an H-shaped cross-section with on the longitudinal sides 43, 44 of the Locking rods 18 formed longitudinal grooves 27, 28, in which protrude the inwardly projecting wall portions 25, 26 how it looks Fig. 5 is apparent. The locking bars 18 are guided in this way longitudinally displaceable in the fitting groove 20, at the same time a movement perpendicular to the longitudinal extension of the fitting groove 20 and thus also a removal of the locking bars 18 is prevented in such a direction.

After loading the spar 17 with the locking bars 18 of the spar 17 and the other spars 19 are according to Fig. 6 each butt joint to form the desired wing assembled and connected to each other in the usual way, for example, welded together, so that in Fig. 7 illustrated wing 29 is generated. In contrast to the known production method, the generated wing 29 is already equipped with the locking bars 18 in this case.

In a next method step, a gear 30 is inserted over the longitudinal opening of the fitting groove 20 in this, as it is in Fig. 7 is indicated by an arrow 31. The transmission 30 comprises a gearbox 32 and elongated cover rails 33 attached thereto, through which the fitting groove 20 is partially covered after assembly of the gearbox 30.

On the underside of the cover rails 33 connecting elements in the form of so-called tooth box 53 are provided, which with corresponding formed on the locking bars 18 teeth 34 (see Fig. 4 and 8th ) can be plugged together so that a positive connection in the longitudinal direction of the locking bars 18 is generated. The tooth boxes 53 are moved upon actuation of the transmission 30, whereby a corresponding longitudinal displacement of the locking bars 18 takes place. By means of the tooth box 53 and the teeth 34, the desired resulting length of the locking rods 18 and the transmission 30 existing fitting arrangement can be adjusted.

After insertion of the transmission 30, this is secured by screws 35 to the spar 17. In principle, the screws 35 can also be omitted. In this case, the transmission 30 can be fastened, for example, by the same fastening screws used for fastening the actuating handle (not shown) of the transmission 30. An attachment via on the operating handle or its rosette provided in the gearbox engaging pins is conceivable. Since the locking bars 18 are already secured by the inwardly projecting wall portions 25, 26 against removal from the fitting groove 20, a further fixation of the locking bars 18 is not required.

In addition, the locking bars 18 are secured against retraction in the longitudinal direction of the fitting groove 20, as it is made Fig. 9 is recognizable.

Fig. 9 shows a partial perspective view of the wing 29 in the region of a connecting corner 36 produced by connecting the spar 17 with one of the spars 19. Thus, it can be seen that the spar 19 has a fitting groove 37 which is formed according to the fitting groove 20 of the spar 17. Also in side walls 38, 39 of the fitting groove 37 inwardly projecting wall portion 40, 41 are formed, since all the spars 17, 19 are usually cut from the originally same profile.

How out Fig. 9 can be seen, after assembling and connecting the spars 17, 19, the fitting grooves 20, 37 aligned at right angles to each other, so that the inwardly projecting wall portions 26 and 41 and the inwardly projecting wall portions 25th (please refer Fig. 5 ) and 40 abut each other in the region of the connecting corner 36 and in each case form a complete wall section extending inwardly around the connecting corner 36 and projecting inwards. When moving the drive rod 18 according to an arrow 42 thus encounter the wall portions 25, 26 encompassing longitudinal sides 43, 44 of the drive rod 18 to the inwardly projecting wall portions 40, 41, thus forming limiting elements for the drive rods 18. The drive rods 18 are thus in a window designed according to the invention captive and installed dismantling.

How to continue Fig. 9 can be seen, a bar exclusion 45 is formed at the end of the drive rod 18, whose width is less than the clear width between the inwardly projecting wall sections 40, 41 and 25, 26. When moving the drive rod 18 according to the arrow 42 can thus the rod exclusion 45 pass through the inwardly projecting wall portion 40, 41 and cooperate in a conventional manner with a corresponding locking element on the frame.

Furthermore, it is off Fig. 9 to recognize that on the locking element 18 additionally common locking pin 46 may be provided.

From the embodiment according to Fig. 10 It can be seen that the laterally extending beyond the gear 30 cover rails can also be designed to be much shorter, so that the drive rods are ultimately visible almost over its entire length from the outside and thus optically form a cover of the fitting groove 20 without a cuff rail would be required. In the embodiment according to Fig. 10 the cover rails are replaced by a uniform short cover plate 47 for the transmission 30. The coupling between the gear 30 and the illustrated drive rods 48 takes place via coupling elements 49, each a pin 50 which projects into corresponding receiving openings 51 in the drive rods 48. Furthermore, the coupling elements 49 comprise teeth 52, which are connected to transmission elements, not shown, of the transmission 30 for longitudinal displacement of the drive rods 48 via the transmission 30.

With the invention, on the one hand, the time required for the production of a plastic window or a plastic door is reduced and, on the other hand, the connecting corners of the inventively designed plastic windows or doors are visually appealing, the drive rods are simultaneously captive and dismantling installed.
