EP1245768A2 - Face-plate for an espagnolette for windows, doors or similar, and an espagnoette with such a face-plate - Google Patents

Abstract

The hollow rail for a window or door drive rod has sections (4,5) in which a stop plate (6) can slide in the longitudinal direction. A cover plate (7) mounted on the rail slides between a position covering the stop plate and an uncovering position. The rail section (4) cover plate (7) can be moved from a rail exposing position to a covering position in a first axial direction parallel to the longitudinal direction of the rail section and locked (12) in position. The cover plate is moved by an actuator (13) which has a guide face (16) co-operating with the cover plate.

Description

The invention relates to a faceplate according to the preamble of claim 1 or 12 and on an espagnolette fitting with such a faceplate.

So-called are used to operate locks on windows or doors Espagnolette or faceplate fittings known that consist of several in one Fitting groove of the window or door sash mounted fitting parts with stored or guided drive rods exist. These fittings and connecting rods are included a faceplate covered, consisting of several in extension to each other subsequent faceplate sections.

The joints or transition areas between the faceplate sections could be very different. For example, when installing the Espagnolette fitting, a faceplate section can be shortened at one end, There are often sharp-edged interfaces, which pose a high risk of injuries. Furthermore, when cleaning a window or Door wing components or fibers of a cleaning cloth etc. on such Interfaces get stuck. There is also the transition between each other subsequent faceplate sections visually unappealing what applies in particular if the cutting of a faceplate section does not match the required accuracy is done. To avoid these disadvantages, has already been suggested the transition between faceplate sections through this Cover sections of overlapping cover flaps or plates. The assembly of the Cuff rail fitting or the fitting elements and associated Forend rail sections are increasingly used Automatic assembly machines, which of course also includes the respective cover plates can be assembled with these machines.

For example, training (DE 25 06 003 A1) is known in which the Transition covering cover plate with two projections in one opening each adjoining faceplate sections engages. For fixation is one Fastening screw provided, which is screwed into the casement. This is known in particular for assembly with an automatic assembly machine Fitting not suitable. In the event of tolerances when assembling the Cuff rail sections occur, there is a risk that the cover plate with their Do not protrude into the openings provided in the faceplate sections can be used and / or that the cover plate after placing again falls off before the fastening screw could be screwed in mechanically.

A connecting rod fitting for windows or doors is also known (DE-GM 77 02 352), in which the respective cover plate is displaceable in the longitudinal direction on one of the adjoining faceplate sections is provided. The cover plate is held captive on the faceplate section in question, must but after assembling the faceplate sections from a pushed back, i.e. the position not covering the transition between the faceplate sections in a position covering this transition can be advanced, which is only mechanically is possible using a relatively expensive tool. Furthermore there is a risk that the cover plate after advancing and after Secure with a screw is not in the desired position.

An overlap connection is also known (DE 198 09 698) in which the Cover plate is secured against unwanted movement. But here is also one additional operation for manual or mechanical moving of the Cover plate required, in addition to fixing or screwing one Locking screw.

The object of the invention is a faceplate and a connecting rod fitting to show, which avoids the aforementioned disadvantages and a simplified assembly enables. To solve this task are a faceplate according to claim 1 or 12 and an espagnolette fitting trained according to claim 15.

The invention allows a simplified assembly of the espagnolette fitting and especially the faceplate and the covers with one Automatic assembly machines, especially in a single operation, but especially in the way that with the screwing one used to fix the cover plate Screw also moving the cover plate out of the non-covering one Position in the covering position.

In FIGS. 1-3, the corner deflection is generally 1 Espagnolette fitting reproduced, which is achieved in a manner known per se a multi-point lock in a fitting groove in the notch of a not shown Window or door leaf is provided. The corner drive 1 includes one out Plastic-made angular guide unit 2, in which a flexible Section 3 'of the drive rod 3 is guided, and a formed as a corner bracket and made of sheet steel faceplate section 4, which with its legs 4 ' just as the guide unit 2 is arranged in the hardware groove of the wing and et al the guide unit 2 covers the outside.

Close the two free ends of the legs 4 'of the faceplate section 4 further faceplate sections, of which a faceplate section in FIG. 1 5 is indicated. Around the transition 6 between the faceplate sections 4 and 5 cover is provided on each leg 4 ', a cover plate 7, which Sheet metal, for example made of sheet steel by bending and punching and in plan view a rectangular blank with two long sides 7 'and two Narrow sides 7 "or 7" '(in particular also Figure 4). The cover plate 7 is displaceable in the longitudinal direction of the leg at the end of the respective leg 4 ' performed, and that over a limited path such that the cover plate 7 after the assembly of the subsequent faceplate section 5 from a position in which the cover plate 7 does not protrude beyond the free end of the leg 4 'into one position is displaceable, in which the cover plate 7 with its the angular corner of the Faceplate section 4 facing narrow side 7 "as far as the free end of relevant leg 4 'protrudes that the transition 6 from the cover plate 7th is overlapped. For this guidance, the two legs 4 'are in the area of their free End each provided with an elongated hole 8, in which the cover plate 7 with a Settlement 9 and with two in the transverse direction of the cover plate 7 against each other offset projections 10 engages.

In order to assemble the connecting rod fitting in a particularly simple manner To enable machine manufacturing facilities, funds are provided that at assembly, moving the cover plate from the non-covering position into effect the position covering the transition. For this purpose, the cover plate 7 a rectangular opening 11 with its longitudinal extension parallel to Longitudinal extension of the rectangular cover plate is in the illustrated embodiment centered between the two longitudinal sides 7 'of Cover plate 7. At the end of the front edge 7 "closer Opening 11 is provided with the bend 9, which is at its opening 11 facing side forms an inclined surface which with the longitudinal extent of the Cover plate 7 includes an angle less than 90 °, which to the Angled corner of the rear narrow side 7 "'facing the corner deflection opens two projections 10 are each on a long side of the rectangular Opening 11, namely near the end closer to the narrow side 7 "' this opening 11 and are made of sheet metal of the cover plate 7 as ear-like Projections formed by pushing them out. The projections 10 serve with their Top of the cover plate facing surface as a support for the countersunk head Fastening screw 12 for fastening or fixing the cover plate 7.

The training is still such that when screwing in Fastening screw 12, which in the embodiment shown by a Opening of the drive rod 3 engages in the material of the window or door leaf, at the same time not moving the cover plate 7 from the transition 6 covering position in the position covering this transition is reached. For this purpose, a socket 13 made of plastic is provided, which has a bore 14 for Carrying out the screw 12 and a trough-like on its top Contact surface 15 for the countersunk head of the screw 12 forms. The width of the socket 13 is is equal to the width of the rectangular opening 11. On one side is the socket 13 provided with a projection which forms an inclined surface 16, in such a way that the distance between this inclined surface 16 and the axis of the bore 14 to Top of the socket increases. The inclined surface 16 acts with the Bend 9 formed inclined surface together. The inclined surface 16 is based on the axis of the bore 14 opposite the socket 13 forms a flat or in substantially flat guide surface 17 which runs parallel to the axis of the bore 14 and when inserted into the opening 11 socket 13 perpendicular to the longitudinal extent of the Opening 11 is. With this guide surface 17, the socket 13 lies with its through Opening 11 and protruding through the slot 8 in the direction of the drive rod 3 End against the free end of a support body 18, which is part of the Management unit 2 is and the u.a. the relevant leg 4 'from the bottom of the Hardware groove spaced.

With increasing screwing of the head against the contact surface 15 of the Socket 13 screw 12 is thus by the on the support body 18th guided socket the cover plate 7 increasingly covering the transition 6 Position moved, namely through the inclined surface 16, so that finally after the completely tighten the screw 12 flush the top of the socket 13 with the Top of the cover plate 7 is and the screw 12 with its head against the support surfaces formed by the projections 10. Herewith is also pressing the socket 13 completed by tightening the screw 12.

The training is preferably made so that the socket 13 in each Position is held by a clamp in the opening 11. It doesn't just mean that possible to pre-assemble the cover plate 7 with the socket 13 and the screw 12, in order to facilitate the attachment of the cover plate 7, but also thereby ensures that the cover plate in every state when the screw 12 is screwed in 7 with the bend 9 and the projections 10 is reliably guided in the slot 8. Through the engaging in the slot 8 bushing is a guide and Anti-rotation device for cover plate 7 when screw 12 is inserted given.

The socket 13 is made, for example, as a molded part made of plastic and has its lower end, i.e. where the inclined surface 16 and the guide surface 17 the have the smallest distance from each other e.g. a square cross section, the is equal to or approximately equal to the width of the opening 11 and which is towards the top of the Bushing 13 increasingly due to the inclined surface 16 to a rectangular Cross section changed.

As shown in particular in Figures 1 and 2, each cover plate 7 is both in their not covering the transition 6, as well as the transition 6 in their covering condition with the greater part of its length on top of the relevant leg 4 'so that when moving from the non-covering State in the covering state only short distances are required and above in addition, the respective cover plate 7 in an optimal manner by means of the fastening screw 12 Is fixed in the middle or approximately in the middle between its ends.

5 shows a modification of a further possible design of a cover plate 7a, which differs from the cover plate 7 essentially only in that a recess or extension on each of the two long sides of the opening 11 11 'is provided, in the beginning, i.e. before tightening the Fastening screw 12 engages a lateral bead of the socket 13. As a result, the socket is in one at least when the screw 12 has not yet been tightened predetermined, very clearly defined position in relation to the opening 11 arranged. When the screw 12 is tightened, these beads then slide under Deformation of the material of the bushing 13 laterally out of the recesses 11 '.

FIGS. 6-8 show the guide unit 2a as a further possible embodiment a connecting rod fitting. This guide unit 2a is the respective one Support body 18 reduced over a material section 19 acting as a hinge Thickness with the free end of each leg 2a 'of the rest of the guide unit 2a connected, in such a way that the respective support body 18 about an axis perpendicular to the longitudinal extension of the respective leg 2a 'over the floor the fitting groove facing away from the outside of the guide unit 2a folded away is and only when the guide unit 2a or the corresponding Corner drive pressed against the bottom of the fitting groove and with the help of Fixing screws is fixed. This will make it a significant simplification the assembly allows, especially in relation to the connection between the guided in the guide unit 2a section of the drive rod and to the Guide unit or corner guide connecting parts of the drive rod. The Support elements 18a in turn form a counter surface for the guide surfaces 17 of the Bushings 13.

FIGS. 9-11 show a guide unit as a further possible embodiment 2b, which corresponds to the guide unit 2a insofar as in turn via the as Hinges 19 acting material sections corresponding to the support bodies 18 Support body 18b pivotable with the free ends of the legs 2b ' Guide unit 2b are connected. At the free end of each support body 18b one socket 13 each is provided. The training is such that at Hardware manufacturer the cuff section 4 designed as an elbow on the Guide unit 2b can be placed, this faceplate section with the elongated holes 8 is pushed onto the bushes 13 on the support elements 18b. The respective cover plate is with its opening 11 on the respective socket 13 attached, in such a way that this socket then over the top of the Cover plate 7 protrudes and the latter with the bend 9 and the projections 10 in the respective elongated hole 8 of the faceplate section 4 engages.

When the screw 12 is tightened, the relative movement takes place Bushing 13 to the support body 18b and by sliding the inclined surface 16 on the Angle 9 moving the relevant cover plate 7 in its covering Position. In the guide unit 2b, the bushes 13 are, for example, on the free one End of the respective support body 18b slidably guided and / or with this end connected by a predetermined breaking point when screwing in the fastening screw breaks and thus the relative movement between the respective socket 13 and the Support body 18b allows.

Figure 12 shows in a very simplified representation and in side view as another possible embodiment a faceplate section 20 to which another Face plate section 21 connects. The transition 22 between these two Forend rail sections can be covered by a cover plate 23. This is in turn, the cover plate 7 is designed to be rectangular and lies at least in its state covering the transition 22 with its long sides 23 ' parallel to the longitudinal extent of the faceplate sections 20 and 21 and with their Narrow sides 23 "or 23 '' 'perpendicular to this longitudinal extension Transition 22 from the narrow side 23 ″ lying further away is by means of the cover plate 23 an articulated connection 24 is articulated on the upper side of the faceplate section 20, in such a way that the cover plate 23 around the perpendicular to the longitudinal axis of the Cuff rail sections 20 and 21 and parallel to the top of the Cuff rail section 20 extending joint axis from the non-covering State in the state covering the transition 22 is pivotable, namely by screwing in a fastening screw 25, which has an opening in the cover plate 23 passes through, and against the action of a spring that the cover plate 23 in the preloaded non-covering position. This opening for the fastening screw 25 is provided approximately in the middle of the cover plate 23. After tightening the Screw 25, the cover plate 23 is additionally secured by this screw.

The spring action is, for example, by a spring in the area of the joint 24 or achieved in that the joint 24 or the cover plate 23rd is at least partially designed as a leaf spring-like element. Basically there is also the possibility of an additional spring element 26 which acts like a leaf spring to provide, which is then between the cover plate 23 and the Faceplate section 20 acts and in the embodiment shown in the Space between the cover plate 23 and the top of the faceplate section 20th is arranged. Similar to the cover plate 7, the cover plate 23 also stands in its the transition 22 overlapping state only with a small part length over the free end of the faceplate section 20 in front.

In FIG. 12, an imaginary plane is indicated by F, which is perpendicular to Longitudinal extension of the faceplate sections 20 and 21 and also perpendicular to the The top of these faceplate sections is and in which the transition 22nd forming end of the faceplate section 20 is arranged. As FIG. 12 shows in the non-overlapping state, the cover plate 23 has its narrow side 23 "on the side of this plane F facing the faceplate section 20, preferably at a distance from this plane, so that in the non-covering Condition of the cover plate 23 a simple assembly, among other things. of the faceplate section 21 is possible.

The invention has been described above using various exemplary embodiments described. It goes without saying that changes and modifications are possible without thereby leaving the inventive idea on which the invention is based becomes. For example, the cover plates 7 and 23 can be very general Transitions between faceplate sections are used and not only at Transitions in the area of corner drives.
