Description

1 2387867
METHOD AND DEVICE FOR CONNECTING A TRANSVERSE SPAR TO THE
FRAME PARTS OF A WINDOW FRAME, DOOR FRAME OR THE LIKE
The invention relates to a method for connecting a transverse spar to frame parts of a window frame, door frame or the like, in which the transverse spar is provided with roof-shaped end faces, whose points are not aligned with the sides of the transverse spar, as well as to a device for connecting a transverse spar to frame parts of a window frame, door frame or the like, in which the transverse spar is provided with roofshaped end faces, whose points are not aligned with the sides of the transverse spar.
The invention provides for the connection of plastic parts of a window frame by means of welding, in which areas of the parts of the window frame are heated to above their melting point, pressed against one another and joined together by cooling.
Heating takes place by a heated welding mirror, which is initially engaged with the areas of the frame parts to be softened and which is then removed before the parts are pressed against one another.
The invention can relate to the connection of transverse spars of any random type to frame parts, but is particularly advantageous in the connection of a transverse spar to frame parts separating two window or door opening halves in such a way that the wings, casements or leaves can be opened and closed in opposite directions. Thus, the stops for the window casements in the case of such a transverse spar are constructed in opposite directions on its top and bottom, e.g. on its bottom in flat alignment with its outer wall, if the casement in the lower window opening of the frame is to be opened towards the interior of the room and the stop on the top and with the inner wall of the transverse spar if the window casement provided there is to be opened to the j -, 1,..

outside. Thus, the stops for the window casements must be arranged in opposite directions on the outer frame parts to be connected to the transverse spar and are not aligned with one another. Hitherto the connection of a transverse spar to outer frame parts of a window or door casement was very complicated and costly in such a case. With corresponding window frames, it was then necessary to proceed in such a way that the outer frame parts were butt welded together, the profile part for one frame part being pivoted by 180 about a transverse axis parallel to the window stop with respect to the other part to be connected thereto. Subsequently the welding bead was removed. Then a V-
shaped notch was sawn into the area of the weld between the two frame parts and subsequently the transverse spar was welded in.
Then the weld was "cleaned" again, i.e. the resulting welding bead had to be removed.
It is obvious that such a method is extremely time-consuming.
Therefore the problem of the invention is to provide a method and a device for joining a transverse spar to frame parts, particularly in the specific case described, which is much simpler and less costly.
In a method of the aforementioned type, the invention solves the problem in that two frame parts to be joined together and connected to the transverse spar are provided on their end faces to be connected and initially a part of their thickness with the roof-shaped end face of the transverse spar with complimentary bevels, that the end faces of all three parts of a weld are jointly heated and that for welding the parts are displaced in relative manner towards one another. For solving the set problem an inventive device is characterized by Y-shaped welding mirrors _, ,, 4.

and moving mechanisms for moving the two frame parts of a weld towards one another, as well as the frame parts and the transverse spar relative to one another.
As it is fundamentally possible within the scope of the invention for the frame parts to be displaced against one another and the spar against them or for the moving mechanisms for the frame parts to be constructed in such a way that the latter can be moved against one another and that a moving mechanism for moving the transverse spar perpendicular to the extension direction of the frame parts towards the same, according to a particularly preferred development of the invention the frame parts are displaced against one another and also against the maintained-
stationary spar and that the moving mechanisms are provided for moving the frame parts against one another and against a maintained-stationary spar. Only in this preferred development is it possible within the scope of the invention to simultaneously weld both end faces of the transverse spar to corresponding frame parts.
It is fundamentally possible for the frame parts to be initially displaced against one another and then jointly against the spar or that the moving mechanisms for moving the frame parts are constructed in such a way that the frame parts are initially movable against one another and then against the transverse spar.
However, preferably the frame parts are simultaneously moved against one another in inclined manner with respect to their extension direction and against the spar or that the moving mechanisms are constructed in such a way that the frame parts are simultaneously movable against one another and against the spar, so that the movement of the two frame parts takes place in a superimposed movement inclined with respect to their extension direction. ...
In alternative developments of the device according to the invention, a one-piece, Y-shaped welding mirror is provided and comprises a V-shaped mirror part and a separate, planar mirror part located on its tip.
Further advantages and features of the invention can be gathered from the claims and the following description of a preferred
embodiment of the invention with reference to the attached drawings, in which: Figs. la) and lb) diagrammatically represent window frame parts to be connected together and the movement steps for connection purposes. Fig. 2 illustrates a welding unit of a welding device according to the invention.
Even though the welding method and device according to the invention can fundamentally be used for the connection of randomly constructed and oriented frame parts of a window frame, door frame or the like, they are preferably used for a stationary window frame to be selected with at least two window openings 3, 4 separated by a transverse spar 2, in which the window casements are to be opened and closed in opposite directions, i.e. in the represented embodiment the window casements in the lower window opening are opened and closed inwards and those in the upper window opening 4 upwards. Thus, the transverse spar 2 separating the two window openings 3, 4 has stop bars 6, 7 for the window casements located in two planes, the stop bar 6 being shown on the outside of the spar and the stop bar 7 on the inside in dot-
dash form. Thus, the stop bars 8, 9 on both window frame parts ll, 12 must be constructed so as to function in opposite directions. They can be produced from the same profile, in which the profile for the frame part 12 is pivoted by 180 about the .. -,:.. I..
transverse axis in the plate plane with respect to the orientation of the frame part 11.
Following the pre-treatment of the individual parts 2, 11, 12, namely the provision of the spar 2 with a roof-shaped end face 13, whose point 13a in the represented construction is located in the median plane of the spar 2, but is certainly not aligned with its side walls, and the provision of the frame parts 11, 12 on their facing end faces lla, 12a which are to be butt welded together with bevels lib, 12b extending over part of their thickness and directed towards the transverse spar 2, the parts 2, 11, 12 can be placed in welding devices in accordance with fig. la and the gap left free between their end faces lla, 12a, 13 can initially be taken up by a one or two-part, Y-shaped welding mirror, with which the end faces lla, 12a, 13a of the bevels lib, 12b are simultaneously heated to above the softening point of the material of parts 2, 11, 12.
The welding mirror is then extended out of the gap between the parts 2, 11, 12 perpendicular to the plate plane and in an extremely preferred development the frame parts 11, 12 are moved against one another and either, following mutual engagement, against the end face 13 of transverse spar 2 or simultaneously with their counter-directed movement against the end face of the transverse spar 2. In the latter case a superimposed movement inclined to the extension direction thereof is performed against the end face 13 of transverse spar 2. The precise movement direction is determined by the angle of the point 13a of transverse spar 2 and in the case of a right-angled point 13a the movement is at 45 to the extension direction of parts 11, 12.
The thus connected frame parts 2, 11, 12 are shown in fig. lb. In the represented, preferred implementation of the method according to the invention, the spar 2 remains stationary and -. ,;, -.,:,
fixed in the inventive welding device and only the outer frame parts 11, 12 are moved against one another. It is consequently possible to simultaneously weld corresponding frame parts to the other, not shown end face of the transverse spar 2 and also in a six-position welding device to weld the frame-bounding transversely directed frame parts directed perpendicular to the frame parts 11, 12 simultaneously to the same or their not shown pendant. A welding unit 21 of an inventive welding device is shown in fig. 2. A corresponding complimentary, homologously constructed welding unit is fixed to the support bars 22 longitudinally facing the welding unit 21. After fixing the welding unit 21 on the support bar 22 corresponding to the length of the transverse spar 2 to be used, in the represented embodiment the support plate 23 for the transverse spar 2 is fixed and stationary. One end of the transverse bar 2 is clamped by a clamping unit 24 to the support plate 23 and its other end is carried and also clamped to a corresponding support plate of the other welding unit. The frame parts 11, 12 are placed on support plates 26, 27 and clamped by clamping devices 28, 28' (see fig. 2). An orienting stop 29 is introduced between the support plates 23, 26, 27.
Following the orientation of the frame parts a welding mirror is introduced and can be moved on following the heating of the end faces of the frame parts 11, 12 and the spar 2. The welding mirror is Y-shaped and is in one piece in the embodiment shown.
The inventive welding unit has a lower moving mechanism 31 for moving the two support plates 26, 27 and also the clamping device 28 for the frame parts 11, 12 in the direction of the arrow 8 on the support plate 23 and consequently the end face of the transverse spar 2 clamped there. In addition, for the moving ..... ,..,. (, i"
mechanism 31 a carrier plate 32 is provided on which working slides 33, 34 are located with which the support plates 26, 27 and the clamping device 28 (which is e.g. connected by means of the plate 26 to the slide 33) are movable against one another in the direction of the arrows B. C. The frame parts 2, 11, 12 to be clamped are initially placed on the plates 23, 26, 27 in such a way that they strike against the orienting stop 29 and are clamped there. Then, by means of an introduced welding mirror (not shown), the end faces of the parts 2, 11, 12 are heated. The welding mirror is then extracted upwards from the gap between the parts 2, 11, 12 and preferably simultaneously the slide or moving mechanism 31, 33, 34 is brought into movement, so that the plates 27, 26 with the frame parts 11, 12 located there are moved against one another in the direction of the arrows B. C and simultaneously in the direction of arrow A against the end face of the transverse spar 2 clamped to the plate 23. The softened end faces of the parts 2, 11, 12 are pressed against one another and welding takes place on cooling the parts.
Then the thus connected frame parts are extracted from the welding device and the points are "cleaned", in that the welding beads are removed, e.g. by scraping off using a knife, grinding off, etc. Finally, it will be understood that the present invention has been described in its preferred embodiment and can be modified in many different ways without departing from the scope of the invention as defined by the appended claims.
