Description

The invention relates to a fitting mechanism for a tilt and turn window or for a Tilt & Turn doors that have a frame and a swing frame, wherein at least one locking device of the fitting mechanism is provided which has a first locking element which can be arranged on the frame, that with a second locking element that can be arranged on the swivel frame cooperates, the second locking element by an actuator the tilt-and-turn window or the tilt-and-turn door with a band of the fitting mechanism can be actuated, the first locking element having a receiving space has an inlet opening for a pin, so that the in first locking element entered pin with a locking area of the receiving space cooperates and so the pivot frame on the frame locked.

Such a fitting mechanism for a tilt and turn window or a tilt and turn door is known. In the past few years it has been several hundred million in Germany Times built. Such tilt and turn windows or tilt and turn doors enable that in a closed position of the actuating element which actuates them, in which the actuator points vertically downwards, the swivel frame is locked in the frame so that the window is closed.

By moving the actuator into a swivel position, which is the case with the tilt and turn windows and tilt doors used up to now, that the actuator is horizontal, the active intervention between the arranged on the swivel frame locking element and that on the frame attached first locking element lifted so that the swing frame then in a manner known per se by swinging open can be opened.

Another movement of the actuator to its tilt position, which is usually is such that the actuating member points vertically upwards it that the swing frame is arranged around at the bottom of the frame Fittings can be tilted.

Recently there has been an increasing need, e.g. B. because of increasing security awareness and because houses are becoming increasingly "intelligent" perform the aforementioned steps automatically. Systems already known appropriate actuators are used for this, but mostly independent solutions realize and not on the known fitting technology described above build and in addition to the known fitting z. B. additional chains and Use spindles. It is typical of the systems known to date that standard actuating element of the tilt and turn window or the tilt and turn door is usually not used or can no longer be used and the actuator is replaced by mechatronic elements.

A drive device is from the applicant's earlier application EP 02011253.8 known for a tilt and turn window or a tilt and turn door that has an automatic Operation of a tilt-and-turn window or a tilt-and-turn door enables, wherein continue to be the standard actuator familiar to consumers both for controlling the automated operation as well as for a manual one Swiveling, tilting or closing the turn-tilt window or the turn-tilt door is used.

With such an automated operation, the problem arises that with a Movement of the second locking element arranged on the swivel frame from its tilted position to its closed position this inevitably must go through its swivel position by opening the window a movement of the swivel frame around its arranged on the frame Swivel fittings allowed. At the time of passage of the second locking element by the swivel position is then disadvantageous and mode of operative engagement between the first and the second locking element lifted so that the swivel frame is unwanted even with light Pressure - e.g. B. by a gust of wind occurring at this time - open can and even more wantonly - z. B. by burglars - be opened can.

It is therefore an object of the present invention to provide a hardware mechanism to further develop the type mentioned at the outset in such a way that an impact protection for a Tilt and turn window or a tilt and turn door is formed.

This object is achieved in that the second locking element the locking device at least one further pin has that the first pin in a first slot, but is self-holding that at least one second pin in at least one second slot self-holding, but is guided so that the first and the second elongated hole are spaced from each other such that the Extent of two interacting pins in their adjacent positions smaller than the width of the inlet opening of the receiving space of the first Locking element is so that the two are in their adjacent positions located pegs can be passed through the inlet openings of the receiving space and can be entered into a central receiving area of the receiving space are that in the direction of displacement of the hinge mechanism central receiving area connects at least one locking area, in the or each at least one pin by a sliding movement of the second locking element is or can be penetrated, and that at least a locking area of the receiving space at least one inhibiting element has, by which a displacement movement of each of the inhibiting element acted upon pin can be effected in the associated elongated hole.

The measure according to the invention advantageously results in a Hardware mechanism created for a tilt and turn window and a tilt and turn door, which is characterized by the fact that a pop-up protection for the tilt and turn window or the tilt and turn door is formed, which prevents the inadvertent opening of the Tilt and turn window or the tilt and turn door reliably prevented.

Advantageous developments of the invention are the subject of the dependent claims.

In Figures 1 and 2 there is now schematically a known tilt and turn window F shown, the frame B and a swing frame W. To operate the swivel frame W, i.e. to tilt, swivel and locking the tilt and turn window F, serves an actuator E, through the one hardware mechanism A - either manually or by a motor Drive unit - can be actuated. The swing frame W is known per se and therefore not described in more detail with known Turn fittings D1 and D2 and also known and therefore not Tilting fittings K1 and K2 on frame B described in more detail attached pivotable and tiltable, which is also known and therefore Tilting rod K, which is no longer described, the swivel frame W in the end position its tilting movement stops or - in the case of a motor drive - the Tilting movement of the swing frame W causes. Regarding such a motor In order to avoid repetitions, we refer to the EP as a drive 02011253.8 of the applicant. The fitting mechanism A also has a known one and therefore no longer described Volume 2, which with the Actuator E of the tilt and turn window F is coupled, so that a - manual or motorized - rotary movement of the actuator E in a sliding movement of volume 2 of the fitting mechanism A is implemented. Through this Sliding movement of the belt 2 becomes a first locking device 10 and two second locking devices 20 of the fitting mechanism A of the tilt-and-turn window F, which serve to swing frame W in the closed position of the tilt-and-turn window F in the frame B too lock.

A first locking device 10 now has a frame B attached first locking element 10a and a cooperating with it second locking element 10b, wherein the second locking element 10b has two pins 11a and 11b, each in a slot 12a, 12b of the Volume 2 of the fitting mechanism A is displaceable, but self-retaining, that is secured against unwanted moving, are arranged. The two Pins 11 a and 11 b pass through a corresponding recess in the Tilt rod K through and act to lock the swing frame W im Frame B in the closed position of the tilt and turn window F with the first Locking element 10a of the first locking device 10 together. This first locking element 10a - as best seen in the figures 3a-3c can be seen - a receiving space 13, which has an entry opening 13a, through which the two pins 11a and 11b in the figure on the left 3a, adjacent position shown - as described below - by swiveling the swivel frame W into the receiving space 13 can occur. To one in the swivel direction behind the Entry opening 13a lying central receiving area 13b of the receiving space 13 is included in each of the two shift directions of volume 2 Locking area 13c and 13d, in each of which an inhibiting device 14a and 14b, which in the case shown here are a compression spring 15 with a stop 16 trained to protrude.

The second locking device shown in Figures 1 and 2 and 4a-4c and 5 20 in turn has two locking elements 20a and 20b, which basically according to the corresponding locking elements 10a and 10b correspond to the first locking device 10. Accordingly, the second one Locking element 20b of the second locking device 20 in turn two slidable in corresponding elongated holes 22a and 22b, but self-retaining guided pins 21 a and 21 b, which with the first locking element 20a of the second locking device 20 interact (see figures 4a-4c). The first locking element 20a in turn has a receiving space 23 with an inlet opening 23a at its central receiving area 23b there is again a locking area 23c and 23d on both sides connects, in each of which an inhibiting element 24a, 24b protrudes, the in the case shown here again designed as a compression spring 25 with a stop 26 is. As can be seen from FIGS. 4a-4c and 5, the first and second locking area 23c and 23d not straight, but kinked and has an outlet opening 23c 'or 23d' through which - as below is described - when tilting and pivoting the swing frame W der Pins 21 a and 21 b from the first locking element 20a of the second locking device 20 can emerge.

The functioning of the fitting mechanism A is shown in FIGS. 3a-3c and 4a-4c, it being assumed that the previously opened one Swing frame W is now closed, so that - as in Figure 2 and in the left figure of Figure 3a and 4a shown - which at this time adjacent to each other in their positions "v" and "y" in the elongated holes 12a, 12b and 21 a, 21 b located pins 11 a, 11 b and 22a, 22b through the Entry openings 13a and 23a in the respective receiving space 13 and 23 of the respective locking devices 10 and 20 can occur. In the figure 2 shown position of the second locking elements 10b, 20b of the locking devices 10, 20 dip the corresponding pins 11a, 11b, 21a, 21 b, in the receiving openings 13, 23, but they lock in this Do not position the swivel frame W in the frame B.

If the actuating element E now moves from its horizontal position into its closed position, in which it is standing vertically downwards, this causes a Shift of the belt 2 in the opposite direction, d. that is, volume 2 shifts upwards in Figures 1 and 2.

The one in the "v" position at the lower end of the first elongated hole 12a first pin 11 a is here from the movement of the band 2 of the fitting mechanism A taken along and overcomes - since it is in the direction of displacement cannot stay behind - thereby the inhibitory effect of the first inhibitory element 14a. Which is in the "y" position at the top of the second slot 12b located pin 11 b is due to its self-holding arrangement in Elongated hole 12b taken from the sliding movement of the band 2. He will at the end of the sliding movement of the band 2 in front of the first inhibiting element 14a positioned so that it does not affect its movement. This will achieved that in the closed position of the actuator E, the two Pins 11a and 11b in the middle and in the right figure of the figure 3a have taken position, in which at least the first pin 11a arranged in this way in the first locking region 13c of the receiving space 13 is that the swing frame W against pivoting in the frame B is secured.

Now the actuator E from its closed position to his Tilt position moved, in which the actuator E points vertically upwards so causes the associated movement of the band 2 of the fitting mechanism A down that the second pin 11 b, which is in the closed position of the Actuator E is located at the upper end of the second elongated hole 12b Has taken position "y" through which belt 2 is carried, for the time being without changing its position in the elongated hole 12b, since it is from second inhibiting element 14b is not yet acted on at this time.

The first pin 11 a is during this initial movement of the belt 2nd retained by the first inhibiting element 14a and thereby passes as a result of Sliding movement of the band 2 from its position "v" in the first slot 12a in its "u" position. Another rotation of the actuator E of its closed position (vertically downwards) in its tilted position (vertically upwards) causes a further shift of the two each at the upper end of the elongated hole 12a or 12b in their position "u" and "y" located pins 11 a and 11 b (see left figure of Figure 3b). The two Pins 11a and 11b are thus at a distance from one another, which is larger than the width of the inlet opening 13a of the receiving space 13. This causes, that when the actuator E passes through its swivel position, in the so far an unintentional or willful opening of the swing frame W was possible, this is now prevented because at least one of the both pins 11a and 11b are located in the locking area 13c or 13d, so that a pivoting possibility of the swing frame W is reliable is prevented. It is thus due to the described configuration of the first Locking device 10 of the fitting mechanism A in an advantageous manner and A popping protection for the tilt and turn window F is formed.

A further movement of the actuator E in the direction of its tilt position and thus the band 2 of the fitting mechanism A coupled to it now that is in its upper position "y" at the top of the second Elongated hole 12b located second pin 11 b in the second locking area 13d of the receiving space 13 of the first locking element 10a protruding second inhibiting element 14b hits. Because the pin 11b - conditionally due to its position in the elongated hole 12b - cannot remain any further (it has has already reached its maximum possible end position in this direction of displacement), when the belt 2 moves further, the second inhibiting element 14b overcome by the pin 11b and in the tilt position of the actuator E then take the two pins 11 a and 11 b in the middle and the right figure of Figure 3b position shown. As can be seen easily the swivel frame W cannot be swiveled in this position, since the second pin 11 b is securely in the second locking area 13d of the Receiving space 13 of the first locking element 10 is located, from which it cannot be moved out by swiveling the swivel frame W.

As can easily be seen from the middle illustration in FIG. 3b, the central one is Receiving area 13b at its opposite opening 13a Side formed such that the overlying the second inhibiting element 14b first pin 11 a in a tilting movement of the swing frame W in this the rear area 13b 'of the central receiving area 13b can retreat, whereby a tiltability of the swing frame W is guaranteed, which Tilting of the swing frame W preferably by a motor drive the tilt rod K, such as. B. described in the applicant's EP 02011253.8, is carried out.

To turn the tilt-and-turn window F in its tilted position Being able to open the pivoting frame W becomes the actuator E moved from its tilt position to its open position, in which the Actuator E is again horizontal. To the tilt and turn window in this position F can be opened by swiveling the swivel frame W, it is necessary that the two are in the tilted position of the tilt and turn window F spaced pins 11a and 11b "pushed together" until they are spaced from each other, which is a passage of the two pins 11a and 11b through the inlet opening 13a of the Receiving space 13 of the first locking element 10a of the first locking device 10 allowed.

A movement of the actuator E from its tilted position into its open or swivel position now causes the now in the direction of displacement of the band 2 behind the second inhibiting element 14b and in its position "y" in second slot 12b located second pin 11 b (see Figure 3b) of the in Figure 3c upward movement of the belt 2 can not follow, since it is held back by the second inhibiting element 14b until it reaches its position "x" in the second slot 12b has reached. The actuator E is then on its horizontal swivel position moves until it is in its position "v" in first elongated hole 12a located first pins 11a in operative engagement with the first Inhibiting element 14a occurs. Another movement of the actuator E in Direction of its tilting position causes by the inhibitory effect of the first inhibiting element 14a the first pin 11a from its position "u" in its Position "v" is moved. At this time, the second pin had 11 b the second inhibiting element 14b already passes. Moving the actuator back E towards its swivel position and beyond towards its tilting position now causes the band 2 to continue in FIG. 3c moved downward, so that the second pin 11 b is in active engagement with the second inhibiting element 14b occurs and by a further movement of the actuator E from its "x" position to its "y" position in the second slot 12b is moved. The two pins 11a and 11b thus take their neighboring Positions "v / y", in which their common outer extent is less than is the width of the inlet opening 13a of the receiving space 13, so that the Swing frame W by a corresponding swiveling movement out of the frame B can be moved out and the tilt and turn window F can thus be opened.

The person skilled in the art can clearly see from the above description that for locking of the swing frame W in the frame B basically the first locking device 10 would be sufficient. Such a window would have the disadvantage, however, that only one opening the swivel frame W opposing locking point would be formed. It is therefore - as already described at the beginning - preferred that the tilt and turn window F has at least one second locking device 20, so that at least one further locking point of the swing frame W in the frame B is formed. The actuation of the pin 21 a and 21 b of the second Locking element 20b of the second locking device 20 takes place here turn over the band 2, so that a synchronous function of the locking elements 10a and 20a, in particular the pin 11a, 11b and 21a, 21b guaranteed is. The function of the second locking device 20 is now explained with reference to Figures 4a-4c, the individual Figures 4a, 4b and 4c with regard to the functional sequence shown therein, that of FIGS. 3a, 3b and 3c correspond.

The pins 21 a, 21 b of the second locking element 20b of the second locking device are in the open state of the swing frame W - the same like the pins 11 a, 11 b of the first locking device 10 - in its central, adjacent position, in the - as from the left picture of the Figure 4c can be seen - the first pin received in the first slot 22a 21a in its "v" position and the second pin 21b in "y" position of the second elongated hole 22b. If the swing frame W is now closed, thus the pins 21 a, 21 b positioned adjacent to one another pass through the entry opening 23a 'of the first locking element 20a into the receiving space 23a a. Now the actuator E from its open or Swivel position moved to its closed or locking position, see above 4a shifts from bottom to top in FIG. 4a. Because the first cone 21 a is - seen in the direction of displacement - in its end position it is not stopped by the inhibiting element 24a. The two pins 21a and 21 b then reach in the closed position of the actuator E - in according to the way the pins 11a, 11b - their in the middle Figure 4a shown position, in which the second Locking device 20 the swing frame W in the frame B locked.

In order to tilt the window, the actuator E becomes vertical from it downward closed position in its vertically upward pointing tilt position moves, which causes that with the actuator E coupled band 2 in Figure 4b moved from top to bottom. Through the Inhibitory effect of the two inhibiting elements 24a, 24b on the pins 21 a, 21 b - Corresponding to the first locking device 10 - achieved that in the tilting position, the two pins 21a, 21b are in their positions "u" and "y" are located, then - as can be seen from the middle illustration of Figure 4b is - a pin 21 a through the inlet opening 23a and the second pin 21 b through the further entry opening 21 d 'from the first locking element 20a the second locking device 20 during a tilting movement of the swivel frame W can leak.

To turn the tilt and turn window F by pivoting the swing frame W To be able to open, the actuator E from its tilt position to his Swivel position moves and the two pins 21 a, 21 b are replaced by the corresponding "Pendulum movement" as in the first locking device 10 described - pushed together, so that then both pins 21 a, 21 b at Swiveling the swivel frame W through the inlet opening 23a from the Recording room 23 can emerge.

The functional sequence for a window hinged on the left, in which the first locking device 10 on the left side of the tilt and turn window F - opposite the rotary fittings D1 and D2 located there, then a second locking element as shown in Figure 5 is required. The expert is the function of such a rotary fitting from the Above description for a window hinged on the right easily derivable, see above that further explanations are not necessary.

It should therefore be noted that the fitting mechanism A described is more advantageous Way a popping protection for a motor-driven in particular Window is formed, which causes the swing frame W during the manual or motorized movement of the actuator E from its tilt position to its closed position and vice versa cannot be opened unintentionally.

With the described fitting mechanism A is thus, even in a manual mode without an electric motor drive, a safe transition from the tilt position guaranteed in the locked position of the tilt and turn window F, and even even if an actuation of the tilt-and-turn window F otherwise by less powerful, e.g. B. elderly or especially disabled people, would be impossible, e.g. B. when a strong wind pressure is a large area Window loaded.

Another advantage of the fitting mechanism A according to the invention is that that the described fitting mechanism A - regardless of a possibly still existing motor or mechatronic protection - the by the Tilt & Turn window F granted burglar protection improved because it is due to Most of the locking pin 11 a, 11 b, 21 a, 21 b always guaranteed is that the tilt and turn window F is not forced from the outside, e.g. B. means a screwdriver, as it is necessary to open the window is the pair of interacting pins 11a, 11b and 12a, 12b not only to move out of corresponding locking areas, but furthermore to push together.
