CORNER DISPLACEMENT DEVICE FOR ACRYLIC ROD BRACKETS

  VES OR RODS FOR CONTROLLING WINDOWS, DOORS OR

OTHER ELEMENTS OF THE SAME TYPE

  The present invention relates to a wedge return device for active rod fittings or control rods for windows, doors or the like in the case where, at the rear face of an angular or angled retaining rail , it is provided

  an element forming a guide channel having a trans-

  C-shaped counterpart which is intended to contain flexible return elements, for example steel strips, so that these return elements can move therein by resisting to traction and compression, guide which comprises two branches connected to each other, so as to form a single

  piece, by a transition part in the form of a circular arc.

  Corner return devices of this kind already exist, the function of which is to couple to one another the active rods or control rods which are maintained / to be able to move and which are guided in two directions. cross-member and jamb members forming an angle of window sash, door leaf or other elements

of the same kind.

  As is apparent from the German utility model DE-GM 1,758,015, in the case of a very widespread type of construction of such

  known corner return devices, the retaining rail which carries the element

  forming the guide channel is made of a cross-sectional material in the shape of a flat rectangle, that is to say elongated, for example flat steel, and is made in the form of a piece

  angle or angle of overlap which has two direct branches

  at right angles to one another, connected to each other,

  to form a single piece, by a transition part of

  manufactured using profiled elements of wood or synthetic

  Tick. On the other hand, however, it is known, for example by the publication DE-AS 1 00 502, of corner return devices in the case of which the element forming the guide channel which is intended to contain the flexible return elements is fixed in

  itself in the area of the angle of the window sill or the van-

  tail of the door and is then covered by a bent or

  cover which must be fixed independently of him.

  Such a wedge return device is also provided for

  be mounted on windows or on doors made of

  spun wood or synthetic material.

  On the other hand, there are still corner return devices in which the elements forming the substantially C-shaped cross section guide channels which are provided to hold the flexible return elements can be attached to the

  means of enclosures or housings angled or angled at angle of

  windows or door leaves that are made of profiled metal elements; in particular light metal profile elements, as is apparent for example from the publication DE-AS 12 69 535 and

  of DE-OS 24 26 030 Shoemakers or hous-

  in this case, these corner return devices are made with regard to the construction so that the wedge return device can be fastened in elements forming profiled guide channels against the flaps. windows 2 S or door leaves which are planned in main order for

  guide the active rods or control rods so that they can

  move in the longitudinal direction.

  All of these known corner return devices are designed to

  In this way, with regard to the construction and mode of

  that their field of use is limited to windows or

  doors in which case cross members and uprights -

  windows or door leaves are located at

  angle to each other and therefore are di-

  rigged one, horizontally and the other, vertically.

  With regard to windows and doors, also -3-

  known and currently used, which have a junction

  cardboard of the right angle between adjacent members and uprights of window frames or door frames and window leaves or door leaves, in particular with regard to windows and doors whose upper elements In the case of sleepers or sleepers, or frames and leaves or leaves, which occupy a position which deviates from the horizontal with respect to the vertical elements or uprights of the sleeping frames or frames and leaves or leaves, it may be the most advantageous case, use under certain conditions

  corner reference of the kind of construction that is known to the public

  In particular, in this case, the guide channel elements which are intended to contain the flexible return elements so that they resist the traction

  and compression are, with regard to the construction, inde-

  hanging rails that serve to cover them and / or which

  these elements may possibly, separately from each other, by a suitable force exerted on their branches, be brought relative to each other at angular positions which

deviate from the right angle.

  A disadvantage, however, is that

  this type of wedge arises from the fact that the element forming the guide channel which is intended to contain the flexible return elements

  and the angular or angled retaining rail must, if it is a question of

  perform adaptation operations, be manipulated and deformed separately.

  of the other A condition to be met by the

  ment forming the guide channel of the corner deflection device

  the subject of publication DE-AS 11 00 502 in order to be

  formed without difficulty is in this case that it is not done as indicated in the concrete embodiment of two strips of flat material fixed to each other by riveting and forming one

  with the other a guide sheath, but on the contrary

  in one piece from a profile element obtained by extrusion

  C-section cross-section. DE-OS No. 20 46 856 also discloses a wedge-return device in which the element forming the

  C-shaped cross-section guide channel which is des-

  to contain the flexible return elements is fixed only by one of its branches to a retaining rail, while the transition part in the form of a circular arc and the other branch of this element forming the channel in this case, the free portion of the element forming the guide channel may also, if necessary, be deformed at the end of the guide channel.

  in such a way that the two branches of the element can take

  a position in which they differ from each other in

  At the right angle After the wedge return device has been mounted, however, it is still necessary to cover the arcuate transition part of the guide channel element and the free of this element forming the guide channel by means of a complementary free rail end and

  fix this end of complementary free rail, using elements of ac-

  special couplings, at the free end of the clean restraint rail

  In the case of corner return devices of this type of construction, it is therefore also necessary that one

  manipulates separately different elements.

  The object of the present invention is to provide a device

  of the kind referred to in the preamble of this memo.

  which, under one and the same embodiment, can find its application in the case of all the embodiments of windows and doors for which there is provided an angled corner piece which are in practice, and that it is possible, by manipulating it in a simple manner, to adapt to the different particular mounting conditions possible. The corner return device must also be constructed in such a way that the same principle can be applied in the case of constructions of windows and doors.

  in all types of materials used in practice (wood,

  synthetic metal, light metal), provided that the angular or angled retaining rail is provided according to the mounting conditions

  result of the particular choice of the material of windows and doors.

  The above-mentioned purpose is achieved, according to the present invention, by the fact that the guide channel forming member is flexibly deformed in its arcuate transition portion of circle, in that the branches of the retaining rail which carries the element forming the guide channel are connected to one another, in the zone of the angle they form, so as to be displaceable angularly relative to each other and in that at least one of the branches of the element forming the guide channel is guided on the adjacent branch of the retaining rail so as to be movable in a measured

limited in the longitudinal direction.

  This embodiment of the return device of

  corner which is the subject of the present invention not only offers the

  vantage that the branches of the element forming the guide channel, which is of C-shaped cross section, and the branches of the

  angled or angled retaining rails can be shared without difficulty

  and in a safe way, be brought relatively to each other, by a small manual effort, to any angular position necessary in practice, but it has at the same time the advantage of asssurer easy guidance, and this , in a sustainable manner, the removal element of

  corner on the element forming the guide channel.

  In the simplest case, a wedge return device designed according to the present invention may be in such a form that the two branches of the retaining rail are connected to one another so as to form a single piece, but so as to be able to

  be bent deformed in the area of the angle they form.

  A peculiarity of realization of the device of return of ccin

  which is the subject of the present invention, which however proved to be

  particularly advantageous and useful is that the two branches of the retaining rail are, in the zone of the angle they form, connected to each other by articulation on an axis perpendicular to the

  In addition, according to another particularity of

  tion of the corner return device which is the subject of this

  vention, the two branches of the retaining rail form with each other a housing or angular or angled housing and they surround

  in this case, at least on three of its faces in the direction of the

  cross section, the element that forms the guide channel.

  A possibility of safe handling of the corner return device which is the subject of the present invention, during the execution of the fixing work, is obtained, according to another embodiment of this device, in that the two branches housing or angular or angled boftier also cover his

  fourth side in the direction of the cross-section, by means of

  these supports come from molding, the element that forms the channel of guid-

  ge, at least in the vicinity of its arc-shaped transition portion, and that the bearing faces are pivotable on the axis of the hinge relative to each other, same as the fact that at least one of the support faces can be moved relative to

  to the element forming the guide channel.

  A particularly advantageous embodiment, from the point of view of construction, of the wedge return device which is the subject of the present invention is obtained if, according to another

  characteristic of the latter, the branches of the housing or housing

  or bent are in the form of molded elements, for example

  -example by die casting of metal or by injection molding

  jection of synthetic material, while the element forming the channel

  guide consists of a profiled rail obtained by drawing or forming

bending.

  In addition, it may be important that, according to another

  As a feature of the embodiment of the wedge return device forming the subject of the present invention, the axis of articulation of the housing or angled or angled housing is provided so that it passes outside the external flexion zone. of the arcuate transition portion of the guide channel member, while the support faces which are displaceable at least with respect to the internal flexion area of the shaped transition portion of arc are attached to the branches of the housing or angular housing
