Definitions

• the present invention relates to fittings for windows and doors.
• the term “coupling fitting part” is used below for the fitting part to be mounted between the extension arm and the fitting part defining the joint axis. This coupling fitting part is to be coupled to a part of the extension arm.
• the extension arm part can be the entire arm or just a part of it, depending on the implementation of the extension arm in individual cases.
• DE 1 923282 shows a locking securing of the coupling between the coupling fitting part and the extension arm part in the form of a leaf spring.
• a locking device for the described rotatability between the two pieces of the coupling fitting part is shown in DE 4040 233, which corresponds to the preamble of claim 1 and the preamble of claim 15, in the form of the spring 32 in FIG. 8.
• the present invention is based on the technical problem of providing a practical and economical solution for fitting parts for the described connection between the articulated axis and the extension arm.
• the invention is initially directed to a fitting set for a window or a door with a coupling fitting part and an extension arm part
• the coupling fitting part comprising: a fixed frame-side first piece for coupling the coupling fitting part to a fixed frame-side joint part with a joint axis, a sash-side part for coupling the Coupling fitting part to the extension arm part, which is to be mounted on the sash frame side, the first and the second piece being fastened to one another, at least in the unmounted state, rotatable relative to one another by 180 ° and can be locked at least in the assembled state in the end positions of this twisting movement with respect to the twisting movement and the second piece and the extension arm part jointly have a coupling device for coupling the coupling fitting part and the opening arm part, which coupling device has a spring for latching the coupling by the coupling device, characterized in that that the spring of the coupling device serves to lock the twisting movement between the first and the second piece of the coupling fitting part.
• the invention is also directed to a correspondingly designed coupling fitting part alone, that is to say without a swing-out arm part, namely a coupling fitting part for a window or a door, which is designed for a fitting set according to one of the preceding claims and has: a fixed frame-side first piece for coupling the Coupling fitting part to a fixed frame-side hinge part with a hinge axis, - a sash-side second piece for coupling the
• Coupling fitting part to the extension arm part which is to be mounted on the sash frame side, the first and second pieces being fastened to one another rotatable by 180 °, at least in the unmounted state, and at least in the assembled position in the end positions thereof
• Rotating movement can be locked with respect to the rotating movement and the second piece of the coupling fitting part has a part of a coupling device for coupling the coupling fitting part to an extension arm part, which coupling device part has a spring for locking the coupling by the coupling device, characterized in that the spring of the coupling device serves to lock the twisting movement between the first and the second piece of the coupling fitting part.
• the invention is also directed to a window and a door with an appropriately designed fitting set.
• the invention combines the two previously known latching possibilities in a common solution and designs them in such a way that one and the same spring is used for both latches.
• the term spring means a separate component of the fitting that is specially designed with regard to its elasticity. A spring is therefore not only in the form of an inherent elasticity of the usual sheet metal parts of such fittings. This is important because the catches should be able to be applied with a not too great effort, so that the fitting part can be installed without tools and without painful hands.
• the spring can of course be firmly connected to one of the fitting parts, that is to say the coupling fitting part itself or the extension arm part, whether detachable or non-detachable, for example by riveting.
• the definition of the invention according to claim 1, that is to say as a fitting set leaves open whether the spring is fastened to the coupling fitting part or to the extension arm part or is to be understood as part of the same. Solutions can also be found in which a spring on the extension arm part also serves to lock the rotary movement between the first and the second piece of the coupling fitting part, as long as this locking only has to take place in the assembled state. However, this is the primary aspect for reasons of stability.
• the spring must be part of the coupling fitting part.
• the invention according to claim 15 is already implemented by a coupling fitting part alone, so it could also be used in a completely conventional extension arm part with a suitable complementary counterpart for the coupling between the extension arm part and the coupling fitting part.
• the term of the fitting set according to claim 1 is of course to be understood in such a way that this fitting set can also contain further fitting parts in addition to the coupling fitting part and the opening arm part, that is to say it can also be a complete window or door fitting.
• Coupling device between the extension arm part and the coupling fitting part consists in the rest of a pin-hole combination, which of course can also be present several times.
• One or more pins can be provided on the coupling fitting part side or on the extension arm part side, and complementary holes in each case on the other part.
• the extension arm part has two pins which can engage in corresponding holes in the coupling fitting part.
• the hole or holes are preferably elongated holes with a narrow section and a wider section.
• the corresponding pin can be inserted through the wider section and then into the narrow section are moved, preferably in the direction of the extension arm, that is, with the wing closed, perpendicular to the hinge axis and parallel to the wing. Then at least one protrusion of the at least one pin can engage behind the narrow section of the elongated hole in order to secure in the direction of the joint axis.
• an adjusting device in connection with this coupling device is advantageous, so that the parts to be coupled with one another, that is to say the coupling fitting part on the one hand and the extension arm part on the other hand, can be adjusted relative to one another over a certain range in the direction of the opening arm. This promotes the universality of the possible uses with differently dimensioned sash frames and also allows fine adjustment on site.
• the adjusting device can have, for example, an adjusting screw, which is advantageously screwed with its thread into the or one of the described pins of the coupling device. Both the screw base and a screw head or both could come into contact with another part, namely that which does not have the relevant pin.
• a leaf spring is preferably selected which covers the wide section of the hole or at least part of it
• Section covers and can and must be pushed up by the pin during insertion.
• the spring should then spring back and thus secure the pin in the narrow section.
• the safety function does not necessarily have to consist in the fact that the spring is in direct contact with the pin.
• it can also secure the pin together with, for example, the head of the adjusting screw by being in contact with it this screw head stands.
• this screw head stands.
• eccentric heads are forms of realization of the adjusting device, for example eccentric heads.
• the spring preferably has a recess into which the pin engages in the coupled state of the coupling device described. Then the spring can be attached to one side of the recess, either on the second piece of the coupling fitting part or on the extension arm part. On the opposite side, it can then be designed such that it can come into engagement with the first piece of the coupling fitting part in order to perform the second latching function.
• the side of the fastening of the spring, the recess and the side of the engagement of the spring in the first piece of the coupling fitting part lie one behind the other in the direction of the deployment arm.
• the engagement of the pin in the recess of the spring can possibly also form an anti-rotation device for the spring in addition to the engagement of the spring itself in the first piece of the coupling fitting part. This means that it only has to be attached at a single point, for example with a single rivet.
• the spring is attached to the coupling fitting part instead of to the extension arm part, as also corresponds to claim 15.
• the pin or pins are then preferably provided on the extension arm part, as is the optionally provided adjusting device.
• a favorable implementation option for the coupling fitting part which is also clarified as an exemplary embodiment, has a sleeve as an articulated sleeve which can be penetrated by the previously mentioned articulated bolt on the fixed frame.
• An element of the coupling fitting part can be attached to this, for example a bent sheet metal, which can also be formed in one piece with the sleeve (the latter as a curl).
• This element leads to a flat section, the flatness of which is perpendicular to the direction of the extension arm.
• This flat section is then penetrated by the axis of rotation for the said rotatability between the first and the second piece, and thus belongs to the first itself Piece to which the joint sleeve also belongs.
• the flat section also has end edges, each with a groove, with an imaginary connecting line between the grooves lying parallel to the hinge axis. By turning the axis of rotation, one or the other groove can now be brought into the area of engagement of the tongue.
• a spring lying flat on the second piece of the coupling fitting part can then be arranged in the correct positions of the twisting movement in the vicinity of the grooves and bent there in order to engage the grooves with the bent end.
• the side of the spring opposite the bent end is preferably used for fastening.
• the previously described optional recess in the spring or another interaction between the spring and the coupling device between the second piece of the coupling fitting part and the extension arm part can then be present between the bent end and the fixed end of the spring.
• the bent end can further, for example, penetrate a hole in the second piece of the coupling fitting part with the base of a U-shape of the bent end.
• the hole lies in an angled section relative to the area of the second piece on which the spring rests flat and serves to guide and hold the bent end when the grooves described are engaged and disengaged, and also as an anti-rotation device for the spring, insofar as necessary.
• Figure 1 is a representation of a set of fittings according to the invention in the coupled state between a coupling fitting part and an extension arm part and Figure 2 shows the same hardware set in the decoupled state.
• 1 shows a coupling fitting part and 2 an extension arm part. These are shown in FIG. 1
• the coupling fitting part 1 initially has an articulated sleeve 3 designed as a sheet metal curl, which is conventional per se.
• This joint sleeve 3 is connected in one piece and initially at right angles to a sheet metal element 4, which in turn merges at right angles into a flat section 5.
• the flat section 5 is penetrated by a hinge axis 6, about which the previously described first piece of the coupling fitting part 1, namely the elements 3, 4, 5, can be rotated relative to the rest of the fitting parts shown, which will still be described.
• the first piece of the coupling fitting part 1 is in one of the two possible mounting positions.
• one of the two grooves 7 present in the narrower end edges of the flat section 5 in the sense of FIG. 1 points downwards, the other groove 7 points upwards.
• an upper leg of a section 8 of a plate spring bent open in a U-shaped manner engages in the lower groove 7.
• the leaf spring 9 is fastened with an end opposite the bent end 8 via a rivet 10 to a flat sheet metal strip section 11 of the second piece of the coupling fitting part 1.
• This section 11 merges at right angles into a second section 12, which carries the already described axis of rotation 6 and is parallel to the flat section 5 of the first piece of the coupling fitting part 1.
• section 11 has two T-shaped elongated holes 13, each of which contains a wide section and a narrow section.
• the broad section is the section 12 facing the second piece of the coupling fitting part, ie facing the hinge axis of the hinge sleeve 3.
• An extension arm part 2 has complementary mushroom head pins 14, which have protrusions on their upper transverse edges (transverse to the direction of the extension arm).
• FIGS. 1 and 2 show that these pins 14 can be inserted through the wide sections of the elongated holes 13 and can be pushed away from the joint sleeve 3 into the narrow sections of the elongated holes 13 by moving in the direction of the extension arm part 2, where then the supernatants section 11 of the second
• the pins 14 thus form with the elongated holes 13 a coupling device in the sense of the description above.
• FIG. 1 shows that in the coupled state this head also comes to lie within the assigned elongated hole 13.
• the leaf spring 9 already described contains a recess 16 shaped essentially in the opposite direction to the elongated hole 13 below it, likewise with a narrow area to the side of the joint sleeve 3 and a wider area on the other side. Finally, the already mentioned bent end 8 of the leaf spring 9 is in engagement with a hole, not numbered in the figures, in the transition from the section 11 to the section 12 and at the foot of the section 12 of the second piece of the Coupling fitting part 1. As a result, the leaf spring is generally secured against rotation.
• the pin 14 facing the joint sleeve 3 must first push up the leaf spring in the region of the narrow part of the recess (or also on the joint sleeve side thereof), on the one hand against the Anchoring by the rivet 10 and on the other hand against the anchoring by the bent section 8 in the hole described.
• the leaf spring 9 bends up until the part of the mushroom head pin 14 corresponding to the protrusions can be moved over the upper side of the section 11 into the narrow region of the elongated hole 13.
• the pin 14 slides into the wide area of the recess 16 of the leaf spring 9 so that it can snap back.
• the contact of the edge between the narrow area and the wide area of the recess 16 against the pin could already provide security, but in fact the head of the adjusting screw 15 ultimately comes into the wide area of the recess 16 and lies against this edge.
• the pins 14 thus have a certain amount of play in the narrow areas of the recesses 13, the abutment of the adjusting screw 15 against the edge of the spring 9 limiting this play with regard to a movement of the raising arm part 2 on the joint sleeve 3.
• the foot of the adjusting screw 15 secures the coupling in the opposite direction.
• the adjusting screw 15 thus forms a replacement for a fit of the pin 14 in the wide area of the elongated hole 13 and / or the recess 16 of the leaf spring 9 in the direction of the extension arm.
• the second pin 14 on the right in the figures secures the coupling device only in the two directions perpendicular to the direction of the extension arm part 2.
• the extension arm part 2 is constructed conventionally.
• the coupling shoe shown in the figures corresponds to the prior art and has nothing to do with the invention as such. Further details of the extension arm and the entire window fitting are also not shown in this respect.
• the invention is already manifested as such in the coupling fitting part 1.
• the extension arm part 2 can be constructed conventionally. However, this does not necessarily have to be the case with the invention; rather, the spring 9 could also be part of the extension arm part 2. Then, however, the rotary movement about the axis of rotation 6 would only be locked in the coupled state between the coupling fitting part 1 and the extension arm part 2.
