Abstract

The device has a coupling device (1) including coupling parts (3a, 3b) movable along a longitudinal direction and adjustable in length. Two positioning legs are pivotably connected with each other and are pivotably movable and fixed relative to a profile rail (2) and the coupling elements, respectively. The coupling parts are brought into detachable connection by moving one of the coupling parts towards another coupling part. Initial movement of the former coupling part without the latter coupling part pre-controls a scissor type-opening relative to another scissor type-opening. An independent claim is also included for a method for parallely positioning a facade element.

Description

Technical area

The present invention relates to a facade element.

State of the art

In the prior art various Ausstellscheren are known as elements of Ausstellvorrichtungen, which are usually referred to briefly with x-Ausstellscheren and y-Ausstellscheren. Examples are in the FIGS. 1a and 1b displayed.

In this case, the x-Ausstellschere 20 after Fig. 1a two substantially equally long Ausstellschenkel 21, 22, which are each connected in their center by means of a pin connection 25 rotatable with each other. Furthermore, such an x-setting scissors 20 has a first rail 23 and a second rail 24 arranged reversely for this purpose. The Ausstellschenkel 21 are at one end by means of pin connections 26, 28 rotatably mounted on the rails 23, 24 and at its other end (eg 27) slidably mounted on the rails 23, 24.

On the other hand, a y-opening shears 40 has two Ausstellschenkel 41, 42, one of which 42 is shorter than the other 41. The shorter Ausstellschenkel 42 is at one end articulated by means of a pin connection 45 approximately in the middle of the longer Ausstellschenkels 41.

For larger or heavier facade elements, two or more pop-up scissors 20 or 40 are used on each side of the facade element, which are arranged vertically one above the other to connect the facade element with the frame. The facade element can then be removed with the aid of e.g. two x or e.g. two y-Ausstellscheren be issued on each side of the facade element substantially parallel to the frame element.

It is also known from the prior art, on the long side of a rectangular frame lying scissors on actuating rods (eg from the utility model DE 202 20 865 U1 ) or drive rods (eg from the patent applications DE 196 11 222 A1 or DE 197 41 728 A1 ) to couple with each other.

In motorized or manually operated Ausstellscheren, the z. B. by a handle down horizontally or with two handles laterally (one side operating lever) are served, there is a problem with slender facade elements that the wings in the lower area always have the desire to have a smaller Ausstellweite than in the upper area. This is because the center of gravity of the façade element is outside the bearing points of the pop-up scissors, and swing out the Ausstellscheren in the direction of the frame until the game of scissors (s) and the drive is exhausted or constraint occurs. In other words, in particular with high or slim facade elements with known Ausstellscheren a precise parallel issuing can not be guaranteed.

Another prior art is document EP 1 288 417 A2 known. Therein, a Parallelausstellvorrichtung is disclosed, which has a common rail with guided coupling parts. The coupling parts are screwed together.

Next is the document as prior art EP 0 899 404 A2 known, which relates to a Ausstellmechanismus for an opening window.

Presentation of the invention

Object of the present invention is to ensure a precise parallel issuing a slim facade element with respect to a frame member.

This object is achieved by means of a facade element according to claim 1. Preferred embodiments can be found in subclaims.

The present invention is based on the idea to arrange the Ausstellscheren of the prior art is no different or expensive to reconfigure and adapt by additional elements specifically to slim facade elements, but the raising movement for the lower scissors (s) differently than for the upper scissors (s) shape. It provides devices by means of which known Ausstellscheren can be easily supplemented and allows this distinction in the deployment movement.

Accordingly, in the present invention two Ausstellscheren be coupled by a coupling device is provided with a longitudinally extending rail and a guided on the rail of the coupling device and from her coupling element. The rail may be provided as a separate component, but may also be integrated in the sash and / or the frame floor. The coupling device can be connected to two Ausstellscheren such that they can be issued with the same Ausstellweg substantially perpendicular to the longitudinal extent of the coupling device. This results in the parallel deployment movement. In addition, the coupling parts of the coupling element are objected to. This makes it possible to spread the control points of the two scissors, so that the lower scissors in front of the upper scissors or further than the upper scissors can be issued. In this way, the facade element can be issued here stronger and forced from the oblique to the parallel position.

The aforementioned coupling device is simple in construction, and can be easily connected to two known Ausstellscheren. The coupling device itself is then attached to a frame member. It may be a sash - including frameless facade elements such as glass as in DE 202 20 865 U1 - or act a frame stick. Depending on the height of such a facade element then also the length of the coupling device is directed. By using two conventional scissors, there are no unnecessary costs for special designs.

The coupling element according to the invention consists of several parts, in particular two parts, which simplifies its length adjustment. The length adjustment is then provided at the interface of the two coupling parts.

Preferably, the coupling device is configured such that the rail, with which it interacts, is c-shaped or Ω-shaped in cross-section. Ω-shaped rails are eg in DE 20 2008 014 643 U1 shown. At this cross-sectional shape, for example in or on the rail, then the coupling element is guided. Instead of a profile rail with c-section or Ω-section could indeed be screwed, for example, a flat bar with slots directly on an existing rail, in which case guide sleeves could be used for attachment. However, this solution is less preferred because with comparable precision of the guide more space would be claimed.

The Ausstellscheren the Ausstellvorrichtung each have two Ausstellschenkel, each one of these Ausstellschenkel with the coupling element, and the other of the Ausstellschenkel is connected to the rail.

The coupling device is designed so that it can interact with profile rails designed as described above. It can therefore be delivered with a rail or alternatively be installed in a present on a sash or frame floor rail.

Detailed Description of the Preferred Embodiments

Hereinafter, a first Ausstellvorrichtung will be described, which, as in Fig. 2 is shown, with two x-Ausstellscheren 20, 30 and a coupling device 1 is provided.

Each of the prior art x-trip shears corresponds to the one in FIG Fig. 1a illustrated scissors. Accordingly, it has a rail 23, 33, which is connected to a facade element or formed in this, or can also be connected to a frame floor or connectable. Each of the x-Ausstellscheren 20, 30, has a first leg 21, 31 which along the respective rail 23, 33, is displaceable, and is guided by this. Further, each of the Ausstellvorrichtungen 20, 30, a second leg 22, 32 which is rotatably but non-sliding on the rail 23, 33 is attached. "Slip-resistant" refers to pivot points or bearing points that are not movable. Both legs 21, 22 and 31, 32 are rotatably connected approximately at their center.

Further, each of the Ausstellscheren on a second rail 24, 34, to which the respective first leg 21, 31 is rotatably mounted but sliding, and on the respective second leg 22, 32 in a longitudinal direction A (extension direction of the coupling device) can be performed.

As in Fig. 2 is shown, the two described x-Ausstellscheren 20, 30 are arranged offset in the longitudinal direction A, and connected to each other by means of a coupling device 1, that the two Ausstellscheren can be adjusted to each other adjusted substantially perpendicular to the longitudinal direction A of the coupling device. The longitudinal direction A shown in the figures extends in practice vertically, wherein the direction of the arrow against gravity. This means that the scissors will be attached to the façade element so that the rotatable but sliding articulation points (26, 28 in Fig. 1a ) above. Such an arrangement causes the force of gravity to drive the closing movement of the façade element and a positive control in the closing direction can be dispensed with.

The coupling device 1 is shown in detail in FIG Fig. 4 shown. It has an extending in the longitudinal direction A rail 2, which has a c-shaped cross-section. In this profile rail 2 with the above-mentioned cross section, two coupling parts 3a, 3b are accommodated in series, and movable along the longitudinal direction A. The two coupling parts form the coupling element. Of course, other components together with the coupling parts form the coupling element. At the respective outer end of one of the coupling parts 3a, 3b, and facing away from the respective other coupling part, connecting elements 4a, 4b attached to the corresponding coupling part 3a, 3b with a movable Ausstellschenkel 22, 32 of an x-Ausstellschere 20, 30 rotatably but push-fixed connect to. Shown is a variant in which the rail is delivered with the coupling device. But it is also conceivable to use the rails, which are usually provided anyway in the sash or frame sticks. For this purpose, only a few fasteners would have to be provided for connecting the coupling parts.

In the in Fig. 4 arrangement shown, the one coupling part 3a and the other coupling part 3b are provided spaced from each other in the longitudinal direction A. At the respective mutually facing end of the coupling parts 3a, 3b connecting devices 5, 6 are mounted, which bridge this distance. The attached to the first coupling part 3a first connecting element 5 in this case has a pin which mounted in the second coupling part 3b second Connecting element 6 is inserted.

Without form and / or adhesion in the connecting element 6, the opening process proceeds as follows. When the one coupling part 3a is moved in the direction of the other coupling part 3b in the longitudinal direction A, e.g. via motor or manual drive, so it slides in the rail 2 until the two connecting elements 5, 6 are brought into abutment. The pin of the first connecting element 5 is preferably introduced into the second connecting element 6 of the coupling part 3b, but can also only rest. If the coupling part 3a is moved further in the longitudinal direction A, the other coupling part 3b is carried along. The introduced into the second connecting element 6 pin of the connecting element 5 ensures a tilt-stable connection between the two coupling parts 3a, 3b.

The initial movement of the first coupling part 3a without the second coupling part 3b serves to pre-control the lower Ausstellschere 20. She will therefore move in front of the upper pair of scissors 30. By this pilot control a larger counter-pressure is built up in the lower part of the facade element to be exhibited, so that the facade element is here somewhat more turned off, and is forced out of the oblique position in a vertical orientation. The times at which the lower pair of scissors and the upper pair of scissors are activated are different. It will be one Spread achieved. About the length adjustment at 5, 6, the spread is adjustable.

In Fig. 3 the effect of this movement is indicated by arrows. As shown, the first coupling part 3a is arranged in the longitudinal direction A at a distance from the second coupling part 3b. If the first coupling part 3a is now activated and moved in directions a parallel to the longitudinal direction A towards the second coupling part 3b, then the first coupling part 3a initially slides independently until it comes into contact with the second coupling part 3b and the two coupling parts 3a, 3b coupled. In this phase, the lower scissors performs a deployment movement a 'from.

From the coupling, the first coupling part 3a forces the second coupling part 3b to move synchronously with. If then the coupled coupling parts 3a, 3b in the directions A, B further moves, so the rails 23, 33 of the x-Ausstellscheren in perpendicular thereto directions a ', b' execute the same extent Ausstellbewegungen. An exhibition of in Fig. 3 Thus, when one of the rails 23, 33 is moved in the opposite direction to a ', b', the coupling parts 3a, 3b also become in one of the directions a ', b' opposite direction moves.

The opening process with positive and / or non-positive connection in the connecting element 6 will be described below with reference to a non-inventive embodiment.

The non-inventive embodiment of a display device is in Fig. 5 shown. This display device has two y-Ausstellschere 40, 50 and a second embodiment of a coupling device 1 according to the invention.

A first Ausstellschere 40 has two Ausstellschenkel 41, 42. The longer Ausstellschenkel 41 is extra rotatably connected in its center with one end of a shorter Ausstellschenkels 42. This connection is ensured by means of a pin 45. Further, the longer Ausstellschenkel 41 at one end to a slider 44 which is in communication with a rail 43, and is guided in a longitudinal groove of the rail 43 in a longitudinal direction A. The rail 43 may be attached to a facade element or a frame floor.

Further, a second Ausstellschere 50 is provided, which also has a longer Ausstellschenkel 51 and a shorter Ausstellschenkel 52, which are connected by means of a pin 55 approximately in the middle of the longer Ausstellschenkels 51 and in an end region of the shorter Ausstellschenkels 52 rotatable with each other. Further, a further pin 54 is provided in an outer end portion of the longer leg 51 to connect the longer Ausstellschenkel 51 with a rail 53 rotatably. This rail 53 is attached to a facade element or a frame floor.

To form the in Fig. 5 illustrated Ausstellvorrichtung the two Ausstellscheren described 40, 50 are arranged mirror images of each other. The free ends 44, 54 of the longer Ausstellschenkel 41, 51 are away from one another, and the ends 45, 55 of the shorter Ausstellschenkel 42, 52 face each other. For alignment and connection of the Ausstellscheren 40, 50 with the coupling device 1, the ends 46, 47 are arranged on 57, 56 in a line along the longitudinal direction A. Both Ausstellscheren 40, 50 are then coupled together by means of a second embodiment of the coupling device 1, so that they are arranged as described below.

The coupling device 1 extends in a longitudinal direction A, and has a profile rail 2, which in cross-section C-shaped is trained. In the rail two interconnected coupling parts 3 c, 3d are added, and along the longitudinal direction A in the rail 2 slidably. The two coupling parts 3c, 3d form the coupling element of the second embodiment, although in turn further components may be involved in the formation of the coupling element.

The first coupling part 3c has a longitudinal groove 7 which extends in the longitudinal direction A. Furthermore, the first coupling part 3c has a connection region 8, which is guided outside the profile rail 2 for easier accessibility but can also be guided in the rail. As in Fig. 5 can be seen, this connection portion 8 is formed to extend in a plane parallel to the plane of the remaining first coupling part 3c plane. Furthermore, a length adjustment 9 is provided in the connection region 8. The length adjustment can be carried out as in the first embodiment.

The length adjustment can also be designed as it is in DE 20 2008 014 644 U1 is described. At its pin (reference 16 in DE 20 2008 014 644 U1 ) and its carrier (reference 2 in FIG DE 20 2008 014 644 U1 ) would then be one of the coupling parts 3c, 3d and at its displacement element (reference numeral 3 in DE 20 2008 014 644 U1 ) and the slot (reference numeral 18 in FIG DE 20 2008 014 644 U1 ) would be by means of in Fig. 5 screw connection 10 shown the other of the coupling parts 3c, 3d attached. It is also conceivable, the length adjustment DE 20 2008 014 644 U1 to modify so that their support and their sliding element are not firmly connected. This would make it possible, as in a variant according to the invention of the first embodiment, to remove the coupling parts 3c, 3d from one another. As a length adjustment can in principle, because of the in DE 20 2008 014 644 U1 described disadvantages, however, less preferred, according to an eccentric GB 2 313 405 A be used, in which the cam (reference numeral 9 in GB 2 313 405 A ) bearing member and the cam follower (reference numerals 21, 7 in GB 2 313 405 A ) are firmly or detachably connected to each other.

In the second embodiment according to Fig. 5 extends the second coupling part 3d as the first coupling part 3c in the rail 2 in the longitudinal direction A. However, it is significantly shorter than the first coupling part 3c formed to leave enough room for maneuver in a deployment movement.

The shorter Ausstellschenkel 42 of the first Ausstellschere 40 is rotatably connected at one of its ends by means of a pin connection 46 but slidingly connected to the first coupling part 3c. Further, the longer Ausstellschenkel 41 of the first Ausstellschere 40 is connected in one end region with a pin connection 47 with the rail 2, that the pin connection 47 extends through the groove 7 of the first coupling part 3c. The pin joint 47 is also a rotatable but non-slip, i. relative to the rail 2 immovable connection. The longer Ausstellschenkel 41 is therefore not in contact with the coupling part 3c.

Further, the longer Ausstellschenkel 51 of the second Ausstellschere 50 by means of a pin connection 57 rotatably and non-slip connected to the second coupling part 3d. The shorter Ausstellschenkel 52 in turn is rotatably connected at one end by means of a pin connection 56 and slidingly connected to the rail 2.

If now the first coupling part 3c is moved in the longitudinal direction A, then the rail 43 of the first deployment shears 40 becomes in a direction substantially perpendicular thereto issued. When the first coupling part 3 c is fixedly connected to the second coupling part 3d, the rail 53 of the second Ausstellschere 50 is also moved by the same amount and in the same direction as the rail 43 of the first Ausstellschere 40. In this way, a deployment movement of the two Ausstellscheren 40, 50 coupled together.

If the rail 43 and / or the rail 53 are displaced in the opposite direction perpendicular to the longitudinal direction A, the other of the Ausstellscheren 40 or 50 is controlled by the coupling device 1 via the coupling parts 3c and 3d so as to perform a same displacement in this direction ,

If, according to the invention, the two coupling parts 3c, 3d are adjustable in length but releasably connected to one another, this second embodiment works just like the detachable variant of the first embodiment. If the two coupling parts 3c, 3d are permanently connected to one another (not part of this invention), the swinging out of a wing can be compensated for by a single adjustment of the length of the coupling element 3c, 3d in the installed state of the paralleling device. The clearance caused by play and tolerances in the joints and in the drive can thus be eliminated, so that when the movement of the removed scissors or shears (in the embodiment, the upper or upper) is converted directly into a deployment movement of the wing, the lower But scissors or scissors have yet to bridge this empty path.

It should be noted at this point that the coupling devices shown can be mounted both on a facade element, as well as on a frame member to form together with two or more Ausstellscheren an opening device in the context of this invention.

It should also be made clear that the display devices shown have indeed two Ausstellscheren, but also a plurality of vertically arranged on one side of a facade element / frame element Ausstellscheren can be used. This is particularly conceivable for very high facade and frame elements.

Furthermore, it can be after Fig. 2 or 3 next to the rails 24, 34 provided the x-scissors rail 2 of the coupling device 1 as well as possibly provided in y-scissors rails. Also can be after Fig. 5 integrated into the y-scissors integrated rail 2 in a comparable manner in x-scissors. The embodiments described above can therefore be combined with one another.
