Description

The invention relates to a closure device for the striking wing double-winged, timberless windows, doors or the like according to the generic term of Claim 1.

DE 35 04 025 A1 discloses a closure device of the type mentioned at the beginning forth. It serves to make the embossing wing double-winged, not a central stringer locking windows or doors for themselves. This is done by manual Actuation of the closure device by means of at least one coupling pin an associated drive rod moves into the locked position. Preferably there are two Driving rods available, which by means of the locking device an opposite Carry out movement, which causes the striking wing both above and below is set. The closure device is housed in the wing rebate, so that when locked window is not visible, d. that is, it will be at the overlapping wing covered. If the overlapping wing is opened, the locking device accessible and can be brought manually into the open position so that the drive rod or the drive rods release the tucking wing. This can then be also open. In the closed position of the locking device there is a detent provided that the operating lever should also secure in the closed position. Around to open the wing is an elongated hole at its free end of the operating lever provided that manual operation by finger intervention in the slot enables. Opening and closing is made more difficult by the latching device due to their self-locking, the material properties are affected, for example due to the design of the material's own elasticity.

In the past, finger intervention in the elongated hole has proven to be a defect emphasized, because the grip of the fingers gives the opportunity to Forend rail of the locking fitting and when opening the window sash touching with your fingertips, which may result in injury, for example, can lead to pinching the fingers. This is supported by a Detent, which due to the self-locking an uncontrolled pull on Operating lever required. From the open position to the closed position Actuation lever at the beginning over a large part of the way over a free one Operating field promoted so that the finger engagement in the slot of the Operating lever without resistance and without hindrance from other fitting parts or window sashes can remain. In the last section just before reaching the parallel one Aligned position of the operating lever and the sash rebate, the operating lever arrives close to the spar of the window sash and the fittings, what in the area of Fingertips can lead to crushing or jamming.

Another disadvantage is that the locking means become very after several switching operations badly worn. Therefore, the rest area must be serviced at certain intervals. This is done, for example, with a lubricant. If not maintenance is with Deposits on the lower horizontal frame spar are to be expected, which is particularly the case with bright ones Windows is very disadvantageous.

EP 0 786 574 A1 describes a locking fitting for locking a Window or door wing on the frame. This fitting is also in the Folding space mounted between the two wings and consists of a faceplate, one under this sliding drive rod, a swivel arm which is in the plane of the Forend rail is pivotally mounted, and a handlebar mounted on the swivel arm forms a pair of scissors for actuating the locking bar together with the rotating arm.

A projection and a recess are provided on the rotating arm and the faceplate, by the mutual engagement of the rotary arm in its parallel to the faceplate Lock position is set. By reaching under a handle and lifting it away from the faceplate, the pivot arm or the projection with the recess disengaged. Here, too, can be on the other fittings or on Window sash an injury cannot be excluded. This solution is also Technically complex, since the component shown here consists of many individual parts exists and also puts down on the price.

The invention has for its object a closure device of the beginning to create the type mentioned, which avoids the disadvantages mentioned above and in particular has a functionally reliable and user-friendly design.

The achievement of the object is achieved by the features of characterizing part of claim 1 solved. The subclaims relate to further advantageous embodiments of the invention.

The locking device can be operated via a single operating lever, the is easily accessible and with a simple push of the button Unlock the actuating lever from the swivel-secured position. At the same time the actuating lever automatically swings into a force storage device free field of activity - the partial opening position - off. This will not only make the necessary operating force is reduced to a minimum, but it is also a smooth swing-out movement from the partial opening position into one Opening position possible without overcoming a locking resistance.

The invention provides that the operating lever protrudes against the handlebar Has latch that in a first congruent position, d. H. in the closed position, with a Interlocking recess of the handlebar interacts. The proposed training causes a relatively simple and easy to manufacture form of swivel lock. The Actuating lever can be manufactured in one step.

The handlebar has a recess during manufacture. The opposite is also a pan backup possible, d. H. the operating lever has a recess and the handlebar a latch on. In this way, no additional components are necessary in order to Generate swivel lock. The closure device is therefore inexpensive.

Another expedient embodiment provides that the latch of the Actuating lever at the end has a section that is approximately parallel to the Thickness of the actuating lever is arranged spaced. This ensures that at the operation of the locking device after overcoming the swivel lock Handlebar is in any case out of engagement with the operating lever.

A particularly advantageous embodiment provides that the handlebar in the area of Locking recess is angled so far in the direction of the actuating lever that the Section of the locking lug of the actuating lever between the top edge and handlebar can reach through. The handlebar can for example also be designed so that it parallel to the faceplate is cranked. A condition to ensure proper functioning is that the section of the latch releases the actuating lever.

According to a further feature of the invention, the locking recess of the handlebar and the detent of the actuating lever a distance from the axis of rotation of the Actuation lever, which should be largely directed away.

It is particularly advantageous that a lot of space for receiving a spring element is present and thus contributes to the improvement of the spring characteristics. Besides, that is Inclination from the handlebar to the operating lever in the area of the locking device on largest dimensioned so that the locking members are also large and therefore dimensionally stable can be designed.

It is advantageous according to a further feature of the invention that the actuating lever by a projection on an energy storage device or in the region of the axis of rotation by a spring or other energy storage or also by the inherent elasticity of the Operating lever, receives a constant constant voltage that the Operating lever tilts at a predetermined angle from the handlebar. That way the operating lever on the one hand permanently from the window sash and other fittings held, on the other hand, the operating lever is in the non-detent position and is always pressed automatically into the recess. Cost and The variant, according to which a Force storage device that automatically swings out by means of a projection and Another advantage is the operating lever with constant constant voltage acted upon.

According to a further feature of the invention, the handlebar is in the region of the pivot pin angled to limit the angle in the direction of the actuating lever. It must there is so much space in the area of the energy storage device that the The energy storage device can move unchecked in order not to reduce the functionality affect.

It is particularly advantageous if the actuating lever and the handlebar are longitudinally symmetrical is formed, whereby a left stop for left windows and a right stop for right window with the same components can be posted. A mix-up of the Side during assembly of the components can therefore not occur.

One is constructive, easy to assemble and technically simple Energy storage device according to the invention when worn by the handlebar. The operating lever is free of in the partially open position and in the open position any components that can impair operation.

It is advantageous according to a further feature of the invention that the Energy storage device is a spring element which is I-shaped. This Shaping allows the closure device with the same components, one Use for window hinges hinged on the left and for hinges hinged on the right Window sash and that after the locking device has been fully assembled.

The actuating lever has a recess on each of its two longitudinal edges on, the end of the energy storage device in, for example, a recess engages and by lifting the operating lever on the energy storage device and thus facing away from the faceplate, the energy storage device into the other Recess is displaceable. This variant allows a symmetrical one Construction of all components at least the closure device. As a result, a Assembly errors can be excluded.

It is particularly advantageous that the actuating lever in a third position - the Open position - is disengaged from the energy storage device. This also makes it easy to move Operation of the wing allowed and despite smooth operation an undesirable automatic shifting of the fitting in the closed position is prevented because the Actuating lever first passes into a second position - the partial opening position, and from the energy storage device, which counteracts the closing, is added. Another embodiment shows that the spring element is also U-shaped can be. Here, too, the embodiment for right and left struck Window sash one use. To achieve adjustment after final assembly, the locking device must be actuated from the operating lever swivel secured position in the open position. So the U- shaped spring element released and depending on the type of execution - for a right or Left stop - rotated by 180 °.

A particularly useful embodiment also provides that at the free end of the operating lever, a trough is provided which is concave in the direction of Forend rail runs. The advantage here is that the actuation of the closure device over the trough takes place, the trough being arranged diametrically to the side of the fitting. Because of the fact that the trough has a full surface and thus in this area keeps all other hardware components covered, there is a risk of injury locked out.

The invention based on several, in the drawings more or less schematically illustrated embodiments described in more detail.

Fig. 1 shows a window 1 comprising a fixed window frame 2 and two window sash 3 and 4 has. The window sash 3 is an overlapping sash; the window sash 4 is designed as an embossing wing. To close the window 1 , the window sash 4 is first brought into the closed position and then the window sash 3 is closed . When opening the window 1 , proceed in the reverse order, that is, first the opening of the window sash 3 is required, and then the window sash 4 can then be opened. The latter is only possible if the embossing window sash 4 has been unlocked beforehand by actuating a locking device 5 . Consequently, the window sash 4 can be fixed to the window frame 2 with the closure device. 5 For this purpose, drive rods which move in opposite directions and which cooperate with corresponding counter-elements of the window frame 2 are moved in or out by the closure device 5 . However, the presence of two drive rods 9 a and 9 b is not necessary for the invention. For the present invention, one of the two drive rods 9 a, 9 b is sufficient to achieve locking of the window sash 4 .

The closure device 5 is shown in more detail in FIG. 2a. It has a one-armed actuating lever 6, the axis of rotation 12 is perpendicular to the face plate 8 and provided on the outside of the faceplate 8, wherein the axis of rotation 12 of the operating lever 6 is connected to a coupling pin 11 a. On the other coupling pin 11 b engages a link 7 , which is articulated at a distance from the axis of rotation 12 of the actuating lever 6 , the actuating lever 6 being secured against swiveling in the faceplate 8 in a congruent position. The swivel lock is carried out via the actuating lever 6 , which has a locking lug 16 projecting against the handlebar 7 , which cooperates with a locking recess 17 of the handlebar 7 in the closed position.

The latch 16 is partially punched out of the operating lever 6 and then pressed out. In a lower-lying area of the groove of the window sash 4 , the drive rods 9 a, 9 b already mentioned above are guided in a longitudinally displaceable manner, ie they are located in the area of the underside of the faceplate 8 according to FIG. 2 a. The closure device 5 includes a power storage device 15 which is provided with a projection 23 that applies a continuing constant continuous voltage on the actuating lever 6, which inclines the control lever 6 in a predetermined angle 29 from the handlebar. 7 The permanent tension can also be achieved, for example, in the area of the pivot pin 30 , by means of a spring, other energy stores 32 or also by the inherent elasticity of the actuating lever 6 , which consists of a stamped and bent part. Furthermore, it can be considered here that the actuating lever 6 is made of a plastic injection-molded part, or else a design as a corresponding element made of spring steel.

In order to limit the actuating lever 6 , which is subjected to a certain preload, to a certain inclination, the handlebar is angled in the direction of the actuating lever 6 at the end of the link 7 in the region of the pivot pin 30 .

As is clear from Fig. 2b, the actuating lever 6 and the link 7 is longitudinally symmetrical. The handlebar 7 has a bore 33 , which is arranged near the pivot pin 30 and serves to receive the energy storage device 15 . The handlebar 7 also has a slot embossment 34 from the bore 33 in the direction of the longitudinal axis, which receives a partial section of the energy storage device 15 . In this exemplary embodiment, the energy storage device 15 is a spring element 19 , which is designed in an I-shape 20 in the unloaded state. The other end of the spring element 19 , which has a projection 36 and extends concavely in the direction of the actuating lever 6 , engages in the recess 22 a in FIG. 2b, with the spring element 19 thus prestressing the actuating lever 6 in the position of the closed position shown here and is held by the locking recess 17 and the locking lug 16 . In this position, the closure device 5 thus assumes a window sash 4 hinged to the right, which is described in more detail below.

In order to move the locking device 5 from its swivel-secured position or locking position - according to FIGS . 2a, 2b - into a partial opening position - according to FIGS . 3a, 3b - it is necessary for the user to use the handle, in this case a trough 31 of the Grips actuating lever 6 and in the actuating lever 6 in the direction of the arrow, ie, presses against the faceplate 8 , so that a section 18 of the locking lug 16 , which is spaced approximately parallel to approximately the thickness of the actuating lever 6 , under the handlebar 7 , which in this area in Direction of the actuating lever 6 is angled toward the faceplate 8 , can reach through between the top edge 14 and the handlebar 7 and, in a second position, as shown in FIG. 3b, changes into a partially open position.

The swivel lock of the locking device 5 , which consists of the locking recess 17 , the locking lug 16 and a section 18 , is spaced as far apart as possible from the pivot pin 30 of the actuating lever 6 in order to achieve the most stable possible construction of the swivel lock.

The closure device is in the second position in a partially open position according to Fig. 3b, so 19 accommodates the spring element to its original shape, so that the spring element unloaded and I-shaped is formed in this layer 19.

. The Figure 4 shows the closure device in a third position - the opening position 24. In this position, the drive rods 9 a, 9 b are extended from the corresponding counter elements of the window frame 2 - not shown here - and the drive rods are delimited via the coupling pins 11 a, 11 b in the elongated holes 10 or, depending on the embodiment, an elongated hole 10 , wherein one of the two axes of rotation 12 , 35 is fixedly connected to the faceplate 8 . The spring element 19 is in the corresponding third position out of engagement with the actuating lever 6 .

In order to pivot the actuating lever 6 back into its closed position, this is done in the reverse order of actuation for opening the window sash. This means that the operating lever 6 must be pressed over the trough by means of manual operation in the direction of the faceplate 8 , in order to then finally change to the swivel-secured position.

In FIG. 5, a displacement of the operating lever 6 is shown, according to which the operating lever 6 by lifting over the force storage device 16 of time and thus of the face plate 8 facing away, wherein the dot-dash specified position of the operating lever 6 shows the raised position and - in Fig. 5a - a projection 36 of the energy storage device 15 which extends concavely in the direction of the actuating lever 6 into a window sash which is hinged according to FIG. 6a or, as FIG. 6b shows, is used for window sash 4 hinged on the left.

In Fig. 6a and in Fig. 6b, the projection 36 of the energy storage device 15 engages in one of the recesses 22 a, 22 b depending on the right or left usability. The dash-dotted energy storage device 15 shows the corresponding unloaded position of the energy storage device 15 when, according to FIG. 5, the actuating lever 6 is in the dash-dotted position.

A further exemplary embodiment is shown in FIG. 7 and in FIG. 7a, wherein the control arm 7 has two receptacles 26 , which are of identical design and receive the U-shaped 21 spring element 19 . On the one hand encloses the housing 26 the U-web 25 and on the other hand projects a free leg 27 a in the handlebar 7 and the other free leg 27 b is formed as a round protuberance, engages through one of the two laterally offset cutouts 28 of the actuating lever. 6 The version shown is a window sash hinged on the right. In order to switch the locking device to a left stop - not shown in the drawing - the locking device must be brought into the open position by actuating the actuating lever 6 from the position secured against pivoting. Thus, the U-shaped 21 spring element 19 is released and rotated through 180 ° depending on the type of design. The free leg 27 b engages in the cutout 28 on the other side of the actuating lever 6 .
