Abstract

The invention relates to hardware for windows or doors made of at least one first and one second hardware part (8.3, 21). Each hardware part (8.3, 21) is made of at least one cover rail (23, 24) and a drive bar (25, 26) displaceable relative to the cover rail (23, 24), the drive bars (25, 26) being connected via a coupling device (29) mounted on the drive bar ends (27, 28) and the coupling device (29) being made of two coupling parts (30, 31). One of the coupling parts (30, 31) recoils in a coupling position relative to the cover rail (24) covering the drive bar (26), while the second coupling part (31) protrudes past the cover rail (23). In order that the drive bars (25, 26) can be subsequently coupled even for hardware components that abut each other flush, according to the invention, the toothed segment (33) has a spacer (36) dimensioned such that said spacer, supported by the second driving bar (25) or the second coupling part (31), holds the coupling parts (30, 31) out of engagement, wherein the spacer (36) has no effect in a potential coupling position.

Description

fitting

The invention relates to a fitting according to the preamble of claim 1.

From EP 1264954 B1, a fitting has become known in which a first fitting part is mounted in a fitting groove on a wing corner. In order to be able to couple the drive rod of this first fitting part to the drive rod of a second fitting part, the second fitting part is provided with a function member engaging under the first fitting part, which is attached to a guide channel of the second fitting part designed as a corner deflection. By the functional member, the drive rod of the first fitting part is raised and the guide channel can be moved under the drive rod. In the guide channel, a coupling member is provided, which is in driving connection via deflecting members guided in the guide channel to a second drive rod orthogonal to the first drive rod.

The coupling member has a projecting in the direction of the drive rod of the first fitting part coupling pin which engages in a coupling position in which the drive rods are drivingly connected in a bore of the first drive rod. As a result, they are drivingly connected in drive rods.

The disadvantage here is that in this embodiment, a stationary attached functional member is necessary, which carries the actual drive rod coupling or leads.

For blunt adjacent rod-shaped fittings such a coupling is not provided. From DE 1224636 C, a releasable coupling for two drive rods has become known, in which provided on each fitting part a faceplate and a longitudinally displaceable drive rod underneath is. The drive rods are drivingly connected to each other via a coupling device. For this purpose, a coupling part is provided on each of the drive rods. The coupling part of the first drive rod consists of a one side formed on the drive rod U-shaped coupling shoe, which engages around the second drive rod at lateral recesses in a coupling position. The drive rod ends of the two drive rods are identical. In the coupling position is at least one end of the cross-drive rod in front of the faceplate, so that the coupling shoe on the corresponding drive rod is accessible from above.

The disadvantage here is that the coupling of the drive rods must be done either before mounting the fitting or at least one of the fittings must be attached to the other fitting part. In this case, the fitting part is to be attached, which has an accessible from above - so visible - rod end. This is particularly undesirable in windows or doors, which are to be equipped with individually suppleable fittings. Exposed interfaces lead to complaints as customers assume that fittings have been forgotten.

In fitting systems as known from DE 19913306 A1, it is also necessary that the fitting parts are first mounted, which are spaced from the wing corners, such as espagnolette gear, locks or the like. The corner deflections are mounted only after assembly of these modules and thereby overlap the already mounted fittings. Accordingly, the coupling points of the Eckumlenkungen are designed so that they cover the coupling points of the latches. The latches have accordingly coupling points which protrude with respect to a faceplate, so that they are accessible from above.

If the need for a further locking point subsequently arises after fitting the fitting, this lock can only be attached after the corner deflection has been installed. The invention is therefore based on the object to develop a fitting so that a subsequent coupling of the drive rods is possible even with butt-fitting hardware components.

The solution of this problem in a generic fitting succeeds by the measures of the characterizing part of claim 1.

By these comparatively simple measures, the standard components can be designed so that they can be coupled with a further fitting part at a later time. The subsequently to be mounted fittings parts can remain largely unchanged and can therefore be in the otherwise provided

Use assembly order. The proposed coupling can also be used in standard assembly also to compensate for unavoidable manufacturing tolerances of the wing in the area of the teeth. When retrofitting a second fitting part, which engages under an already mounted fitting part, this balance can not be used. However, in these cases, the fitting components associated with the frame are not fixed anyway due to the retrofitting. Accordingly, the relative orientation can take place here by corresponding displacement of the frame-side component.

Further advantageous embodiments will become apparent from the claims 2 to 5.

Thus, it is provided that the spacer is integrally formed as projecting from the drive rod in the direction of the coupling shoe end portion, which is associated with an opening in the second drive rod in the coupling position, wherein a joining edge is attached to the end of the coupling part and / or the drive rod. As a result, a particularly simple manner of manufacturing the fitting parts is achieved. The necessary geometric shapes can be produced inexpensively by stamping. -A-

If the spacer is designed as a projecting in the direction of the clutch shoe projection on the first drive rod, the opposite in the coupling position a recess in the clutch shoe, wherein the projection has at least one joining bevel, results in a variant that takes up very little space.

It can be advantageously provided that the projection is arranged integrally on the drive rod, so that the production of the drive rod can be particularly simplified.

In a preferred embodiment, the spacer is formed as a T-shaped end portion of the first drive rod whose width is dimensioned larger than the clear distance of the U-section forming U-leg of the clutch shoe and that the U-legs with at least in the direction of the first Driving rod lying joining bevels are provided. This creates a very simple and universally usable coupling point, which is also very easy to produce.

Further advantageous embodiments will be apparent from the figures. It shows:

1 is an overview of the fittings that can be attached to a possibly not yet assembled from the various wing spars wings

2 shows a first embodiment of the coupling device in a view in bottom and a side view,

Fig. 3 shows a second embodiment of the coupling device in a view in the bottom and a side view and

Fig. 4 shows another embodiment of the coupling device. The sash shown in Fig. 1 consists of an upper horizontal frame leg 1, a lower horizontal frame leg 2, a closure-side vertical frame leg 3 and a band-side vertical frame leg 4. In the illustrated embodiment, the wing is shown in an exploded view, the items are not to scale ,

The locking device is a drive rod fitting with a drive rod 5, which is covered and guided by a face-plate 6. The espagnolette fitting is added in a known manner in a stepped stepped groove of the sash. A not shown here, arranged on the closure side operating handle, which sets different switching functions of the locking device in different rotational positions, engages by a pinion of an espagnolette drive 7, which generates a longitudinal movement of the drive rod 5 depending on the position of the operating handle. Corner deflections 8.1, 8.2 and 8.3 deflect the sliding movement of the drive rods 5 by 90 ° to the respective adjacent frame legs.

So that the tilt-turn wing can alternatively be opened or tilt-open, a pivot bearing 9 is on the band side at the bottom - not shown here - frame and hinge side near the upper frame leg 1, a pivot bearing 10 is provided. On the pivot bearing 10 a Ausstelllenker a display device 20 is articulated. The wing formed from the frame legs 1 to 4 is set via locking pins 13.1, 13.2, 13.3 and 13.4 by engaging behind the frame mounted bolt engagement relative to the frame. to

Fixing the wing in the tilted position engages the Kippverriegelung 14 in the tilting bearing 12 locking, so that the wing can be pivoted about a lower horizontal axis, wherein the extension arm 1 1 limits the opening width. In the rotational opening position of the extension arm 1 1 with respect to the 20 designated on the over the Lock element 15 set and held in a parallel position to this.

In addition to the already indicated components of the locking device, namely the drive rod drive 7, the Eckumlenkungen 8.1, 8.2 and 8.3, the display device 20, 1 1 and the extension 19, which carries the tilt lock 14 in the illustrated embodiment, is still an extension 20 on the camp 9, 10 supporting wing side provided.

In a conventional assembly sequence of the drive rod drive 7, the Ausstellvorrichtung 20, the extension 19 and the extension 21 in a folded side open to the step-like stepped Beschlagaufnahmenut to the frame legs 1 to 4 are attached. This can be done with an already assembled wing. However, it can also be provided that the attachment to the loose frame legs takes place, which are only subsequently connected to a frame. Also, the assembly of two to an angle or three U-shaped frame legs is possible.

If the respective frame corner has been formed from two of the frame legs 1 to 4, the corner deflection 8.1, 8.2 or 8.3 assigned to this frame corner can be mounted. For example, the corner drive 8.2 overlaps the drive rod drive 7 and the display device 20. Die

Corner 8.3 is mounted according to EP 1264954 B1 and thereby pushed in the direction of arrow 22 under the display device 20.

2, a first embodiment of the coupling device of the corner 8.3 and the extension 21 is shown in sections. Each of the fitting parts 8.3, 21 has a faceplate 23 and 24 and a relative to the faceplate 23 or 24 displaceable drive rod 25 and 26. The cuff rails 23, 24 are assigned to a stage of the fitting groove and cover lying in the fitting receiving groove drive rods 25th , 26 off. The drive rods 25, 26 are connected via a coupling device 29 attached to the drive rod ends 27, 28. The coupling device 29 consists of two coupling parts 30, 31. The first coupling part 30 is formed by an extending along a portion 32 Zahnungsabschnitt 33 on the longitudinal narrow side of the drive rod 26. The production of the drive rod 26 takes place from a flat-rectangular metal strip which is cut laterally by means of a punching tool. The toothing portion 33 attached thereto is complementary to the toothing 34 of the second coupling part 31, which is attached to the drive rod 25. The coupling part 31 is embodied as a U-shaped coupling shoe 35 encompassing the toothing section 32, the longitudinal dimension of which is dimensioned somewhat smaller than that of the partial section 32.

In the illustrated coupling position of the Zahnungsabschnitt 32 is set back relative to the drive rod 26 covering the face plate 24 and is hidden under this. If therefore the assembly of the extension 21 is dispensed with, the coupling part 30 remains hidden behind the face-plate rail 24. On the other hand, the second coupling part 31 protrudes beyond the face-plate rail 23 in the longitudinal direction. An assembly of the extension 21 therefore requires that the section 32 is inserted from above into the U-shaped cross section of the clutch shoe 35.

But so that the assembly can be carried out at an already mounted corner 8.3 it is provided that the Zahnungsabschnitt 33 has a spacer 36. This is dimensioned so that it is supported on the second drive rod 25 or the second coupling member 31 when the drive rod 25 is pushed under the face-plate 24. The spacer 36 is formed in the embodiment shown in FIG. 2 as a T-shaped end portion 37 on the drive rod 26. The width 38 of the end portion 37 is dimensioned larger than the clear distance 39 of the U-section forming U-legs 40, 41 of the clutch shoe 35, so that the end portion 37 can not engage in the region between the U-legs. Characterized in that the U-legs 40, 41 with at least in Direction of the first drive rod 26 lying joining edges 42 are provided, the coupling shoe 35 can engage under the drive rod 26 and lift it and are moved in the longitudinal direction to this, without causing a positive fit of the teeth of the Zahnungsabschnitts 33 and the clutch shoe 35.

By the spacer 36 in the form of the T-shaped end portion 37 which holds the coupling parts 30, 31 during the longitudinal displacement of the drive rod 25 out of engagement, the drive rods 25, 26 are displaced relative to each other. If the end section 37 is guided past the coupling shoe 35, the end section 37 engages behind the coupling shoe 35 on its rear side 43. As a result of the restoring forces caused when lifting the drive rod 26 and possibly the faceplate 24, the drive rod 26 is moved in the direction of the drive rod 25 that in the possible coupling position of the spacer 36 is ineffective and the serrations 33, 34 interlock.

In this case, a provided at the end of the drive rod 26 joining bevel 44 at the end portion 37 is advantageous because the deflection of the drive rods 25, 26 are favored thereby, when they meet. It is of course expedient if the cuff rails 23, 24 are so close to each other that the coupling position is reached and the drive rods 25, 26 are covered again. The assembly of the extension 21 can thus be done even with a mounted corner 8.3.

A further embodiment is shown in FIG. 3. For better illustration of the clutch shoe 35 is not shown hidden here, although this is hidden by the drive rod. Here, the spacer 36 is formed as an angled end portion 50 of the drive rod 26. This is based on the insertion of the drive rod 25 on this or the clutch shoe 35 from. For this purpose, an insertion bevel 51 pointing in the direction of the drive rod 25 is provided, which if necessary with another to be attached to the drive rod 25 and the coupling shoe 35 and not shown here introduction be added.

When inserting the drive rod 25, the drive rod 26 is raised. The dimensioned in relation to the distance 39 smaller width of the spacer 36 can be performed at a further displacement between the U-legs 40, 41 of the clutch shoe 35 therethrough. If the toothing section 33 is in a position in which a coupling with the coupling shoe 35 would be possible, the end section 50 reaches a recess 52 in the drive rod 25 and engages in this. However, the drive connection of the drive rods 25, 26 is also created here preferably via the positive connection of the serrations 33, 34, so that the recess 52 can be dimensioned larger than the longitudinal dimension of the end portion 50. This facilitates the engagement of the end portion 50, without that to a loss of lift in a movement of the drive rods 25, 26 comes. This is shifted alternately, so that it would come with a generous dimensioning to an idle stroke.

A further embodiment of the invention is shown in FIG. 4. Here, the spacer 36 is formed as a projecting in the direction of the clutch shoe 35 projection 55 on the drive rod 26. In the coupling position, the projection is a recess 56 in the clutch shoe 35 opposite, so that here on reaching the coupling position of the spacer 36 can no longer be supported on the drive rod 25 and the toothings 33, 34 interlock. In order to enable meshing, it is also provided here that the projection has at least one joining bevel 57.

Here it can be advantageously provided that the projection 55 is integrally formed on the drive rod 26.

The aforementioned embodiments allow for subsequent mounting of the extension 21, without the corner 8.3 be dismantled got to. But it is also ensured that at the corner 8.3 a small manufacturing cost arises. All drive rods 25, 26 can be produced by punching technology.
