EP2754803B1 - Espagnolette fitting for a window or door and driving rod for such an espagnolette fitting - Google Patents

Description

The invention relates to a locking bar fitting for a window or a door according to the preamble of claim 1 and a locking bar for a locking bar fitting according to the invention.

Such a locking bar fitting is from EP 1 867 822 B1 known. Therein it is stated that the locking bars engage on one side behind an undercut longitudinal groove of a frame spar of a casement of a window or a door, as well as corner drives, which have resilient elements for engaging in an opposite undercut of the longitudinal groove.

To mount the locking bar fitting on the sash frame, the locking bars must first be positioned, i.e. inserted into the undercut grooves of the frame member and then the end of the corner fittings connected to the locking bars.

Closing elements for locking with counterparts attached to a fixed window frame are screwed to the locking bars.

Since a web of the locking bar or corner fitting that engages behind an undercut of the longitudinal groove is rigid, assembly, i.e. insertion into the longitudinal groove, is only possible by pivoting, which, however, requires a corresponding space, in particular between the undercut and the Reason of the longitudinal groove requires. As a result, these components lie with a relatively large amount of play in the longitudinal groove, which certainly results in functional disadvantages, in particular when the closing elements engage with counterparts on the frame.

In addition to the functional disadvantages, the assembly described is also problematic. This is mainly because the locking rods must be of an exact length in order to enable the required precise screw connection with the corner fittings.

In the DE 198 59 587 A1 a locking bar is disclosed which has two parallel, elastically deformable clamping legs which engage behind an undercut longitudinal groove of a frame member.

From the WO 2012/143792A1 a locking bar is known in which a rib of a frame spar is clamped between a first section 23 and second lateral ribs 24 .

From the DE 12 82 514 B a locking bar fitting is known in which a coupling element is positively connected to a locking bar. This coupling element is used to attach a closing element, for example.

The DE 44 45 793 C1 focuses on a locking bar fitting with several locking bars, corner fittings, a chamber mechanism and a locking element. However, nothing can be found in this literature about the attachment of the locking bar fitting to the sash frame of a window.

Here, too, the functional problems arise due to the relatively large play between the locking bar and the frame member, especially since the clamping legs are not supported on the underside, i.e. the locking bar is supported exclusively by the locking bar resting against the inwardly directed projections limiting the undercut .

The invention is based on the object of further developing a locking bar fitting of the generic type in such a way that its functionality is improved and its assembly becomes simpler and more cost-effective, while at the same time finding a locking bar for such a locking bar fitting.

This object is achieved by a locking bar fitting with the features of claim 1 and a locking bar with the features of claim 8.

According to the invention, it is provided that the locking element is latched to the associated locking bar, with the locking bar having a flange on whose opposite longitudinal sides parallel and spaced apart clamping legs are formed, which are V-shaped in cross section, each with an inner leg and an outer leg , which is resiliently movable to the inner leg.

This results in significant advantages with regard to assembly, since additional fastening parts and their handling, such as screws or the like, can be dispensed with. The introduction of corresponding bores, in particular threaded bores, is now no longer necessary, which results in quite remarkable advantages in terms of production costs.

For locking, corresponding locking elements are provided in the locking bar and the locking element, which, according to one embodiment of the invention, consist of grooves provided on the locking element and bars of the locking bar lying therein, these bars being a continuation forms a leg engaging behind the undercut of the longitudinal groove of the frame member.

To prevent displacement of the locking element and for precise positioning on the locking bar, the locking bar has at least one row of holes extending in the longitudinal direction for receiving at least one tooth of the locking element. Two rows of holes are preferably provided on the locking bar, which run parallel and spaced apart from one another and in which several teeth of the locking element engage.

In principle, the teeth can additionally or alternatively also form clamping elements in correspondence with the holes of the rows of holes, with a corresponding configuration.

Manufacture and assembly are also simplified by the latching of the corner fittings and/or the chamber mechanism and/or the opening stay provided according to a further exemplary embodiment of the invention, which is then connected to the frame member using securing means, in particular in the form of clips are, these clips on the one hand being held in a form-fitting manner on the corner fittings or on the chamber mechanism or on the opening stay and on the other hand in a form-fitting manner on the frame member.

Fastening means, such as screws or eccentric clamps, which were required in the past and which have to be assembled and operated manually, can now be dispensed with, which results in simplified and therefore faster and more cost-effective assembly.

Incidentally, such clamps are very easy to produce as bent/stamped parts. The simple manufacture also relates to the locking elements with their latching or locking means, it being possible for the locking elements to be produced using the injection molding process.

The invention also relates to a locking bar for a locking bar fitting according to the invention, with a flange on whose opposite longitudinal sides parallel and spaced apart clamping legs are formed that are V-shaped in cross section, each with an inner leg and an outer leg which is resiliently movable relative to the inner leg .

The cross section of the locking bar is designed or dimensioned in such a way that the clamping legs rest against the bottom of the longitudinal groove of the frame member when the locking bar is in the functional position.

When the locking bar is pressed into the longitudinal groove, if the clamping legs are appropriately dimensioned in relation to the height of the undercut, the clamping legs may be slightly deformed until a nose edge formed on the outer leg element comes to rest against the undercut. Due to the restoring forces inherent in the clamping legs, the nose edges are pressed against the undercut when supported on the base of the longitudinal groove, so that the locking bar is held tightly clamped to the frame member without play.

The locking bars are preferably made of plastic, being produced by extrusion. Alternatively, the locking bar can also be cut to length from a bar and made of light metal or steel, preferably stainless steel, with the connection area of the inner and outer limbs being configured such that the outer limb is resiliently movable relative to the inner limb. The holes of the at least one row of holes are then made by punching, for example. The inherent rigidity of the bar material is reduced to such an extent that it can be rolled up and practically represents a semi-finished product that can be cut to the required length directly during assembly of the locking bar fitting.

The corner fittings in the form of corner guides and an opening scissor, in particular a rotary tilt scissor, and a chamber gear for actuating the locking bar fitting are positively connected to the locking bars so that they are secured against displacement. For this purpose, the corner fittings have rows of pins at the ends and the chamber mechanism has rows of teeth which engage in holes in the at least one row of holes in the adjacent locking rod. The opening scissors can of course also be arranged outside of a corner area.

The pins of each row of pins are at least partially of different lengths and are arranged in such a way that an arcuate course results with the effect of an attachment aid. This means that when the locking rods are attached, the longer and then increasingly the shorter pins engage in the holes one after the other. Likewise, to facilitate attachment, the pins can be beveled or conical on the outside and/or inside at their free ends.

A latch bar fitting, a window equipped therewith and a latch bar are described below with reference to the accompanying drawings.

In the figure 1 is a locking bar fitting for a window or door shown on a in the figure 2 Casement 8 shown as a partial section can be fastened.

The locking bar fitting has corner fittings connected to one another by locking bars 1, two of which are designed as corner deflections 2 and one as an opening scissor stay 3, here as a rotating/tilting scissor stay. A corner bearing 4 is provided opposite the opening stay 3 . Furthermore, a chamber gear 5 is connected to locking rods 1, as well as locking elements 6 are attached thereto.

The locking bar fitting is held in undercut longitudinal grooves 10 of frame members 9 which form the casement 8 .

To attach the respective locking bar 1, this has what is particularly clear in the Figures 3-5 as can be seen, has two clamping legs 13 which are arranged parallel and at a distance from one another and are designed in a V-shape, forming an inner leg 15 and an outer leg 14 running at a distance therefrom, which can be elastically bent in the direction of the inner leg 15 when the locking rod 1 is inserted into the longitudinal groove 10 is.

while the Figures 3 and 4 show the locking bar 1 each as a detail is in the Figure 5 a) - c) the assembly of the locking bar 1 can be seen in successive steps.

In the Figure 5a ) the locking bar 1 is shown before it is inserted into the longitudinal groove 10. The Figure 5b ) shows a central position in which the outer legs 14 are moved in the direction of the inner legs 15 in order to be able to press the locking rod 1 into the longitudinal groove 10. In the Figure 5c ) Finally, the latched with the frame member 9 position of the locking bar 1 is shown.

It can be seen that each outer leg 14 has an integrally formed nose edge 16 in the area of contact with an undercut 22 of the longitudinal groove 10 has, which in the end position of the locking bar 1 ( Figure 5c ) rests against the undercut 22. Opposite, in the connection area of the outer leg 14 with the inner leg 15, a bead-like support web 19 is formed, which bears against the base of the longitudinal groove 10.

In the cross-sectional continuation of the outer leg 14, there is a contact strip 20, which rests against an edge delimiting the undercut 22 of the longitudinal groove 10 and which carries a hammer-head-like support part 21, which projects towards the inside, i.e. towards the opposite support surface 21, as a locking strip 17.

The width of the locking bar 1 in the area of the nose edges 16 is dimensioned such that under deformation of the outer leg 14, as in FIG Figure 5b ) shown, a simple pressing of the locking bar 1 is possible, the Nasnkanten 16 reach under the undercuts 22 in the end position of the locking bar 1. A sufficient contact pressure is ensured by the restoring forces inherent in the clamping legs 13 in order to press the contact strips 20 , which form a sliding surface, against the edges delimiting the undercut 22 .

A flange 18 connecting the two clamping legs 13 is formed as a recess 37 on the underside, ie facing the support webs 19 arranged at a distance therefrom.

Furthermore, based on a longitudinal axis L ( 3 ) mirror-symmetrical locking bar 1 in the area of the flange 18 has two rows of holes 11 arranged parallel and spaced apart from one another, with a large number of essentially rectangular holes 12, for example.

In these holes 12 teeth 25 of rows of teeth 24 are inserted with those in the Figures 6-9 are provided as detail recognizable closing elements.

There are the figure 6 a latched with the locking bar 1 closing element 6 again, which is in the Figures 7 and 8 is shown in different views in isolation.

It can be seen that this closing element 6, which is provided with a closing roller 23, has two rows of teeth 24 spaced apart from one another on each side in the longitudinal direction, each of which is positioned towards the outer longitudinal edge a clamping web 26 is assigned, with an insertion bevel 28 and a groove 27.

That in the figure 9 The closing element 6 shown, which is equipped with a closing piece 29, has a continuous row of teeth 24 and assigned to each row of teeth 24 is a continuous clamping web 26, ie extending over the entire length or almost the entire length of the closing element 6, with the insertion bevel 28 and the continuous groove 27

In the Figures 10-12 is the assembly, ie the latching of the locking element 6 with the locking bar 1 shown in different steps. Starting from the in the figure 10 shown position, in which the closing element 6 and the locking bar 1 are still completely separated, is in the figure 11 recognizable that the teeth 25 are already partially inserted into the holes 12.

The figure 12 finally shows the complete latching of the locking element 6 with the locking bar 1. It can be clearly seen that the two opposing latching strips 17 of the support surfaces 21 engage in the grooves 27, whereby a latched positive connection is produced. When the locking element 6 is inserted into the locking bar 1, the clamping legs 13 are spread apart by the insertion bevels 28 until the locking strips 17 coincide with the grooves 27 and are pressed into the grooves 27 by the restoring forces inherent in the clamping legs 13. The locking element 6 is thus held securely on the locking bar 1 in every direction.

The figure 13 shows the configuration of a chamber mechanism 5 for a non-displacement connection with connected locking rods 1.

For this purpose, the chamber gear 5 has a bracket 30 at both ends, each of which has two rows of pins 31 arranged parallel and spaced apart from one another and extending in the longitudinal direction, consisting of a large number of pins 32 arranged one behind the other in a staggered manner.

Such rows of pins also have in the figures 16 and 18 Corner fittings shown as a detail, where in the figure 16 a corner drive 2 and in the figure 18 an opening scissors 3 are shown. In the figure 17 the corner drive 2 connected to the locking bars 1 is shown, with the rows of pins 31 protruding to the outside of the corner drive 2, so that the respective locking bar is attached from above. In the figures 14 and 15 is the assembly of the chamber gear 5 can be seen, in which this is first inserted into the longitudinal groove 10 of the frame member 9 and then the locking bar 1 is pushed onto the pins 32 of the rows of pins 31 until the locking bar 1 is locked with the longitudinal groove 10, according to the figure 15 . The tabs 30 lie in the recess 37.

The corner fittings, i.e. the corner drives 2 and the opening stay 3, are also installed in the same way as mentioned above. The pins 32 of the rows of pins 31 are in the longitudinal extension of the corner fittings or the chamber mechanism 5 in their length or, in relation to the bracket 30, in their Height so different that there is an arcuate, mirror-symmetrical course, resulting in a simpler guidance when placing the locking bar 1. This also contributes to the fact that, as in the figure 19 it can clearly be seen that at least part of the pins 32 are beveled at their ends.

In the figure 20 an end area of the corner drive 2 is shown as a detail, with the locking bar 1 being recognizable shortly before it is placed on the rows of pins 31 .

As can be clearly seen, the clear dimension a of the holes 12 in the longitudinal direction of the locking bar 1 corresponds to the outer distance between two adjacent pins 32 to one another, while the gaps b between two pins 32 correspond to the width c of a wall between two holes 12, so that a very precise adjustment of the locking bar 1 is possible, which always corresponds to the size of the gap b between two pins 32 which engage in a hole 12 in pairs.

The latching of the corner drive 2, the opening scissors 3 and the chamber mechanism 5 with the longitudinal groove 10 of the frame member 9 takes place by means of positively held brackets 33, as shown in the Figures 16-18 and the figure 22 are recognizable as a detail.

The figure 21 shows the corner drive 2 held in the longitudinal groove 10 by means of the clamp 33. To prevent the clamp 33 from shifting, projections 35 formed on both sides of the corner drive engage in cutouts 34 of the clamp 33, while a clamp bracket 36 engages behind the undercut 22 of the longitudinal groove 10.

When the clip 33 is inserted into the longitudinal groove 10, the clamp brackets 36 are pressed together until the corner drive 2 assumes its final position in the longitudinal groove 10 and the clamp brackets 36 spread to below the undercuts 22.
