Description

The invention relates to a door or window brake device for a window or a door according to the preamble of claim 1.

Generic windows or doors have already become known. In the known door or window brake devices, a rail element in the form of an aluminum profile is mounted flush in an edge surface of the door leaf or window sash. A metal slide within the aluminum profile is pivotally connected by a slot opening in the upper wall of the profile directly to a strut element about an axis parallel to the door leaf or window pane. A similar braking device is from the SE 442 655 B known, according to which a combination of a rotary piston and a window brake are disclosed together.

Further, reference is made to the EP 1 718 829 B1 , In this case, an arrangement for a door, a window or another suitable cover member having a rotary support with a straight end piston attached thereto. In addition, a friction brake is connected via a gear with this, which allows operation by moving the end piston. In this case, a spindle is provided which has a central bearing and an eccentrically arranged motion transmission pin, which is mounted so that it is accommodated in an attachment for a brake gear housing. Further, the aforementioned eccentrically arranged motion transmission pin is accommodated in a curved recess or other guide in the aforementioned brake gear housing.

The GB 690 796 A refers to a window brake, which consists of pairs of guide strips, between which a guide slot for a guide pin is formed, which is attached to a pivot arm and pivotally mounted.

The aforementioned brake contains no drive rod with a piston with a straight end. The aforementioned brake is also not on the sliding movement of the end piston in operative connection. The pin is held in position by a pawl in the guide slot and the window is held in the open position by moving a guide bar toward the second guide track to lock the pin between the aforementioned guide strip pairs.

The known window brake devices have the disadvantage that, due to possible occurring vibrations and / or vibrations, for example by wind, the braking force of the window brake device wears off and ultimately becomes ineffective. The wing is therefore mechanically not braked and can unintentionally perform independent movements in the soffit, which can cause damage to the window or the door.

The object of the present invention is therefore to eliminate the known deficiencies and, in contrast, provides a system with a door or window brake device for a window or a door, which in a simple, fast, safe and precise way the connection with low cost and small space reached an espagnolette fitting.

This object is achieved by a door or window brake device for a window or a door having the features of patent claim 1.

The door or window brake device is to be arranged so that it is suitable for a wing as a turn or turn-tilt wing for a window or a door.

In this case, the movable wing on a door or window brake device for a window or a door, with a rail element, which is designed for mounting along a frame in a fitting groove of a wing of the window or the door. Between an open and a closed position of the window or the door, a longitudinally guided in the rail member slider is movably arranged, which is pivotally connected to a first end of the Ausstellarm. The second end of the stay arm is formed in rotatable connection with the frame. An actuator rod extends along the track member and rotates by actuation of the gate or fitting of the window or door about a longitudinal axis, the actuator rod having a non-circular cross section and cooperating with the slider such that the actuator rod rotates between first and second angular positions. In the first angular position of the actuating rod, the slider slides freely along the rail member. In the second angular position, the actuating rod moves the slider such that the slider is locked in the rail member.

A simple movement-transmitting coupling results from the fact that the actuating rod engages with the end remote from the slider with engagement in the cross-section of the actuating rod adapted recess of a spindle movable on a corner member, a positive operative connection, wherein with actuation of the espagnolette by displacing a drive rod with coupling of the spindle, the spindle capable of rotation and granted a rotational movement of the actuating rod.

Preferably, the spindle is formed of a central bearing and an eccentrically arranged cam, the drop-shaped in cross-section dwells in a L-shaped backdrop of the drive rod movable. With actuation of the espagnolette fitting along the direction of displacement of the espagnolette fitting, the spindle rotatably follows the length profile of the backdrop transient in a transverse course of the scenery and is automatically rotated automatically about its own axis. While maintaining the positive connection of the spindle in the backdrop during the entire course of the movement of the espagnolette fitting, the cam in the slot form fit the position in the direction of displacement and direction of rotation about the axis of the spindle. With automated rotation of the spindle transmitting to the actuating rod and weiterführendem transition to the slidably mounted in the rail element slider, a controlled controlled braking effect is possible. At the same time, the spindle keeps its position by means of positive locking.

It has proven to be advantageous to the function, installation and cost of the fitting that the spindle is mounted in extension of the axis, offset from the cam by means of a pin, rotatably mounted in a faceplate of the corner member. To secure an unwanted displacement of the spindle perpendicular to the axis of the spindle, secured simply and inexpensively in a groove of the spindle standardized locking ring / lock washer, the spindle itself rotatably mounted in the face-plate from.

In order to continue to meet the character of a smooth-to-use espagnolette fitting, also to manage with little space, the cam of the spindle of the material thickness of the drive rod is adapted adapted. Cost-effective, space-saving and functional advantages result from the fact that the drive rod is guided on the underside of the face plate slidingly movable.

For a sliding and displaceable transition of the cam of the spindle of the length profile in the transverse course in the backdrop and vice versa, the cam at its drop-shaped end at an acute angle expiring a radius, with a radius between the length and transverse course of the backdrop comes to the plant. The shaping design of the teardrop-shaped cam with the radius and the radius in the transition region of the L-shape of the scenery, is also decisive for an automatically controlled rotational movement of the spindle about its own axis.

Simple in the production and good sliding properties of the spindle during actuation of the espagnolette fitting are achieved in that the cam is adapted to the axis of the spindle with a diameter of the radius of the gate, the diameter of the spindle of the width of the length course of the gate slidably matched is.

A rotation of the spindle about its own axis, is desired only in the transition region of the length profile to the transverse course of the backdrop. Within the length of the rotation of the spindle is to be avoided, since the espagnolette is braked during its operation, which can adversely affect the applied torque of an actuating handle for actuating the espagnolette. To avoid the above disadvantages, the cam has a, on the basis of the diameter projecting corner, which results from a linear contour of the teardrop-shaped course with tangential transition to the diameter of the cam and a right angle to the contour and tangential to the diameter oriented, line-like contour , The corner preferably leans flat against the side surface of the link in the region of the longitudinal course in the longitudinal direction of the drive rod and thus prevents rotation of the spindle.

For complete exhaustion of the rotational movement of the spindle within a predetermined space of the wing for the espagnolette, the backdrop continues to follow the radius at the end of the transverse course with decreasing contour of the transverse course of a radius at which the drop-shaped end of the cam of the spindle leans along and positively controlled a wing braked end position occupies.

For a simple and cost-effective production, and a design with good sliding properties and low maintenance, the spindle is made of a die-cast or a castable material.

Preferred embodiments of the invention are shown schematically in the drawing and are explained below with reference to the figures of the drawing.

The 1 shows in perspective view of a window or a door 2 , a frame 4 with an at least rotatable wing 6 , To operate the movable sash 6 , is usually on a vertical spar 39 of the grand piano 6 an operating element provided as a hand lever, which one on the wing 6 arranged espagnolette fitting 12 controls. With operation of the operating element, the movable wing can be 6 , For example, from a locked closed position in a corresponding to the 1 opposite the fixed frame 4 rotate in an open position, and also by means of a window brake device according to the invention 1 in a secured against rotation open ventilation position or bring a portion of a through hole. The wing 6 is supported by one or more rotatable and / or tiltable hinges on the frame 4 held.

The window brake device 1 is on the wing 6 , preferably in a fitting groove 5 to 1 , with the espagnolette fitting 12 movably attached and has a corner component 15 with a friction brake 40 on. The corner component 15 is on the vertical spar 39 of the grand piano 6 with the espagnolette fitting 12 to 1 about one on a drive rod 17 arranged toothed coupling 41 to 2 slidably coupled. In addition, the drive rod has 17 at the transition of the vertical spar 39 to the horizontal spar 42 of the grand piano 6 for moving a spindle 16 on that with an operating rod 11 operatively connected the translational movement of the drive rod 17 in a rotational movement on the actuating rod 11 converts and onto one in a rail element 3 arranged slide 7 transfers. The in the slide 7 - Not shown - friction brake 40 acts with the rail element 3 together, brakes the one on the wing 6 having Ausstellarm 8th and holds the wing 6 in a raised position to the frame 4 firm or gives the wing 6 free for a rotational movement.

To empower the slider 7 in the rail element 3 to block is the operating rod 11 with the slide 7 distant end 13 to 5 in engagement with a cross-section of the actuating rod 11 adapted recess 14 standing at the corner component 15 movable spindle 16 , and enters into a positive operative connection. Upon actuation of the espagnolette fitting 12 by moving the drive rod 17 , is achieved by coupling the spindle 16 on the drive rod 17 , the spindle 16 capable of rotation and on the actuating rod 11 transfer.

By means of simple and inexpensive construction of the drive rod 17 and the spindle 16 which together after 2 a central warehouse 18 of the corner component 15 Meanwhile, little space is needed.

To 2 to 4 , is the spindle 16 from an eccentrically arranged cam 19 formed, with a drop-shaped in cross section training in an L-shaped backdrop 20 the drive rod 17 lingers. Upon actuation of the espagnolette fitting 12 along the direction of displacement of the espagnolette fitting 12 to 10 , follows the spindle 16 rotation inhibiting the length course 21 the scenery 20 and goes after 11 and 12 in a cross-section 22 the scenery 20 over, with the cam 19 the transverse course 22 positive fit necessarily following a rotation of the spindle 16 to the own axis 23 causes. The window brake device 1 is located after 12 in a rotated end position, wherein the friction brake 40 in the slide 7 in a braked operative connection in the rail element 3 stands and the extension arm 8th in a desired open position of the wing 6 to the frame 4 holds.

In a hole 43 the faceplate 25 of the corner component 15 to 2 and 6 , is the spindle 16 in extension of the axle 23 detached from the cam 19 by means of a pen 24 rotatably mounted in stock. The protection against falling out of the spindle 16 from the drive rod 17 , takes place after 6 with one in a groove 38 mounted standardized circlip / lock washer.

In 3 can be seen, is the cam 19 the spindle 16 the material thickness of the drive rod 17 adapted trained. For a free guided movement of the drive rod 17 , is the spindle 16 in the longitudinal direction of the axis 23 to 8th Divided into three parts, with a first circular section 44 the recess 14 wears, set off from the section 44 the middle section with the cam 19 and a corner 32 forming, and with further scaled down to create the last section of the pen 24 with a diameter 30 , By training the spindle 16 , can the drive rod 17 to 5 on the bottom 26 the faceplate 25 slidable lead.

So that the braking effect controlled on the slider 7 acting friction brake 40 can be transferred and the Ausstellarm 8th on the wing 6 holds in a predetermined rotational position on demand, forms after the 3 and 10 to 12 the cam 19 at its drop-shaped end 27 at an acute angle W expiring a radius 28 out with the radius 29 between the length and transverse course 21 . 22 the scenery 20 comes to the plant. The radius 28 of the cam 19 also ensures an almost smooth rotatable course within the scenery 20 the drive rod 17 ,

Decisive for the translational displacement of the fitting with automatic conversion into a rotational movement is the shaping of the cam 19 in interaction with the adapted shaping of the scenery 20 , The 12 shows that the cam 19 around the radius 29 the scenery 20 automatically controlled a rotation of the spindle 16 causes and the course of the scenery 20 leader follows.

Moreover, from the 12 seen that the cam 19 around the axis 23 the spindle 16 with a diameter 30 the radius 29 is adjusted, with the diameter 30 after the 10 and 11 the width 31 the length course 21 the scenery 20 slidably guided. In this case, the cross section of the cam 19 with the diameter 30 for the spindle 16 and the scenery 20 for the spindle 16 with the radius 29 circularly congruent to each other.

In the movement section of the length course 21 to 10 , is a rotation of the spindle 16 undesirable because during the Betätigungsverlaufs the espagnolette 12 on the operating handle an increased torque and thus for the operator increasingly builds up a resistance. To avoid rotation of the spindle 16 in the length course 21 the scenery 20 , is on the cam 19 the corner 32 to 9 forms, resulting from a linear contour 33 the drop-shaped course with tangential transition at the diameter 30 of the cam 19 and a right angle to the contour 33 and tangential to the diameter 30 oriented line-like contour 34 results. The corner 32 leans back 10 anti-rotation while driving through the length course 21 the drive rod 17 flat on one edge of the backdrop 20 on, on the opposite side of the backdrop 20 the drive rod 17 linear at an edge of the backdrop 20 is guided.

After the 3 and 4 , shows the scenery 20 continuing the radius 29 following at the end 35 of the transverse course 22 the contour of the transverse course 22 reducing a radius 36 on, at which the teardrop-shaped end 27 of the cam 19 the spindle 16 inspired. With the radius 36 on the drive rod 17 , arises at a small width of the drive rod 17 a maximum rotation of the spindle 16 and a tight fit in an end position of the movement drive rod 17 and thus the espagnolette fitting 12 , wherein the window brake device 1 in one the wing 6 located position.

Furthermore, the corner component 15 to 10 a locking device 45 on, consisting of one on the faceplate 25 having cutout 46 which extends between an angled transitional region of the vertical spar 39 and the horizontal spar 42 of the grand piano 6 located and as a guide for a stake exclusion 47 the drive rod 17 to 10 in a locked closed position located position of the wing 6 to the frame 4 having driving rod fitting 12 is trained. The bar exclusion 47 works in one after 10 having locked locked position of the wing 6 to the frame 4 to 10 with engagement in one of the frame 4 - Not shown - arranged closing part as additional locking of the espagnolette fitting 12 , followed by 10 the espagnolette brake device 1 in an unchecked the slide 7 movable position.
