Abstract

The invention relates to a locking device (5) for the overlapped wing of two-wing windows, doors or such like, which do not have central posts. Said device comprises one or two adjustable coupling pins (11a) for a driving bar (9) which can be adjusted in opposite directions and are guided in at least one elongated recess (10) of an overlap rail (8). The device also comprises a one-armed actuating lever (6). The pivot pin (12) of the actuating lever (6) is connected to a coupling pin (11a) and the other coupling pin (11b) cooperates with a control rod (7) which is joined to the actuating lever (6) in an articulated manner at a distance from the pivot pin (12) of the actuating lever. In the position congruent with the overlap rail (8) the actuating lever (6) is secured against swiveling. The actuating lever (6) can be moved perpendicular to the rabbeted surface (13) of the window wing (4) so that the anti-swivel mechanism is released. By means of an energy storing device (15) the actuating lever (6) automatically moves from the congruent position, i.e. away from the rabbeted surface (13) of the window wing (4), into an area where it can be moved freely.

Description

Locking device for the underlapping wing of double-leaf timber without doors, doors or the like.

The invention relates to a locking device for the embossing sash of double-leaf, setless wood windows, doors or the like. According to the preamble of claim 1.

DE 35 04 025 A1 discloses a closure device of the type mentioned at the outset. It is used to lock the underlapping wing of two-wing windows or doors without a central spar. This is done by manually actuating the locking device, which moves an associated drive rod into the locking position by means of at least one coupling pin. Preferably there are two drive rods which perform an opposite movement by means of the locking device, as a result of which the striking wing is fixed both above and below. The locking device is accommodated in the sash rebate so that it is not visible when the window is closed, ie it is covered in the overlapping sash. If the overlapping wing is opened, the locking device is accessible and can be brought into the open position manually, so that the drive rod or the drive rods release the underlapping wing. This can then also be opened. In the closed position of the locking device, a detent is provided which is also intended to secure the actuating lever in the locking position. In order to open the wing, an elongated hole is provided at its free end of the actuating lever, which enables manual actuation by finger engagement in the elongated hole. This is made more difficult Opening and closing by the locking device, which is influenced by the material properties due to its self-locking, for example by the design of the material's own elasticity.

In the past, finger intervention in the elongated hole has proven to be a defect, since reaching through the fingers gives the possibility of touching the faceplate of the locking fitting and opening the window sash with the fingertips, which can lead to injuries, for example, pinching the finger can lead. This is supported by a detent, which requires an uncontrolled pull on the operating lever due to the self-locking. From the open position to the closed position, the actuating lever is initially transported over a large part of the way over a free actuating field, so that the finger engagement in the elongated hole of the actuating lever can remain without resistance and without hindrance from further fitting parts or window sashes. In the last section shortly before reaching the parallel alignment position of the actuating lever and the sash rebate, the actuating lever comes close to the spar of the window sash and the fittings, which can lead to crushing or jamming in the area of the fingertips.

Another disadvantage is that the locking means wears out very heavily after several switching operations. Therefore, the rest area must be serviced at certain intervals. This is done, for example, with a lubricant. If maintenance is not carried out, deposits are to be expected on the lower horizontal frame spar, which is very disadvantageous, especially in bright windows.

EP 0 786 574 A1 discloses a locking fitting for locking a window or door leaf on the frame. This fitting is also mounted in the rebate space between the two wings and consists of a faceplate, a sliding rod that can be moved under it, a rotating arm that is pivoted in the plane of the faceplate, and one Handlebar mounted on the swivel arm, which together with the swivel arm forms a pair of scissors for actuating the locking bar.

On the rotary arm and the faceplate, a projection and a recess are provided, by the mutual engagement of which the rotary arm is fixed in its blocking position parallel to the faceplate. By reaching under a handle and thus lifting it away from the faceplate, the rotary arm or the projection can be disengaged from the recess. An injury to the other hardware components or to the window sash cannot be excluded here either. In addition, this solution is technically complex, since the component shown here consists of many individual parts and also depends on the price.

The invention has for its object to provide a closure device of the type mentioned, which avoids the disadvantages mentioned above and in particular has a reliable and easy to use design.

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

The locking device can be operated via a single actuating lever, which is easily accessible and can be unlocked from the pivot-proof position by simply actuating it by pressing the actuating lever. At the same time, the actuating lever automatically swings out through a force storage device into a free actuating field - the partially open position. This not only reduces the necessary actuation force to a minimum, it also enables a uniform swiveling movement from the partially open position into an open position without overcoming a latching resistance. The invention provides that the actuating lever has a locking lug projecting against the handlebar, which in a first congruent position, ie in the closed position, cooperates with a locking recess of the handlebar. The proposed further development brings about a relatively simple and easy-to-manufacture form of the swivel lock. The operating lever can be manufactured in one step.

The handlebar has a recess during manufacture. Conversely, swivel locking is also possible, i.e. the operating lever has a recess and the handlebar has a locking lug. In this way, no additional components are required to create a swivel lock. The closure device is therefore inexpensive.

Another expedient embodiment provides that the latching lug of the actuating lever has a section at the end which is spaced apart approximately parallel to and approximately the thickness of the actuating lever. The result of this is that when the locking device is operated after the swivel lock has been overcome, the handlebar is in any case out of engagement with the actuating lever.

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

According to a further feature of the invention, the latching recess of the handlebar and the latching lug of the actuating lever are at a distance from the axis of rotation of the actuating lever, which should be largely directed away. It is particularly advantageous that there is a lot of space for receiving a spring element and thus contributes to improving the spring characteristic. In addition, the inclination from the handlebar to the actuating lever is greatest in the region of the latching device, so that the latching members can also be designed to be correspondingly large and thus dimensionally stable.

It is advantageous according to a further feature of the invention that the actuating lever receives a constant constant voltage which protrudes the actuating lever at a predetermined angle by means of a projection on an energy storage device or in the region of the axis of rotation by a spring or other energy accumulator or also by the inherent elasticity of the actuating lever tends from the handlebar. In this way, the operating lever is permanently held on the one hand by the window sash and other fitting parts, on the other hand, the operating lever is in the non-detent position and is therefore always automatically pressed into the detent recess. The variant, according to which an energy storage device causes the automatic swiveling out by means of a projection and a further projection to apply a constant constant voltage to the actuating lever, has proven to be economical in terms of cost and production technology.

According to a further feature of the invention, the handlebar is angled in the region of the pivot pin to limit the angle in the direction of the actuating lever. There must be so much space in the area of the energy storage device that the energy storage device can move freely so as not to impair the functionality.

It is particularly advantageous if the actuating lever and the handlebar are longitudinally symmetrical, as a result of which a left stop for left windows and a right stop for right windows can be struck with the same components. The side cannot be mixed up when the components are assembled. A power storage device according to the invention is constructive, easy to assemble and easy to use if it is carried by the handlebar. In the partially open position and in the open position, the actuating lever is free of 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 designed in an I-shape. This shape enables the locking device for the same components, a use for left-hinged window sash and for right-hinged window sash, and after the locking device has been fully assembled.

The actuating lever has a recess on each of its two longitudinal edges, the end of the energy storage device engaging in a recess, for example, and by lifting the actuating lever above the energy storage device and thus directed away from the faceplate, the energy storage device can be moved into the other recess. This embodiment variant allows a symmetrical structure of all components, at least the closure device. As a result, an assembly error can be excluded.

It is particularly advantageous that the actuating lever is in a third position - the open position - out of engagement of the energy storage device. This also allows easy operation of the sash and, despite its ease of movement, prevents the fitting from being moved automatically into the closed position, since the actuating lever first changes to a second position - the partial opening position - and is absorbed by the energy storage device, which counteracts the locking.

Another exemplary embodiment shows that the spring element is also U-shaped can be trained. The embodiment for right and left hinged window sashes is also used here. In order to achieve an adjustment after final assembly, the locking device must be moved from the swivel-secured position into the open position by actuating the actuating lever. This releases the U-shaped spring element and rotates it by 180 °, depending on the version - for a right or left stop.

A particularly useful embodiment also provides that a trough is provided at the free end of the actuating lever, which trough is concave in the direction of the faceplate. The advantage here is that the closure device is actuated via the trough, the trough being arranged diametrically on the side of the fitting. Due to the fact that the trough has a full surface and thus keeps all other fitting parts covered in this area, there is no risk of injury.

The invention is described in more detail below on the basis of a number of exemplary embodiments which are illustrated more or less schematically in the drawings.

1 shows a window 1 which has a fixed window frame 2 and two window sashes 3 and 4. The window sash 3 is an overlapping sash; the window sash 4 is designed as an embossing sash. 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, the procedure is reversed, that is, the window sash 3 must first be opened and then the window sash 4 to be able to open. The latter is only possible if the embossing window sash 4 has been unlocked beforehand by actuating a locking device 5. Thus, the shutter 4 of the window sash 4 can be fixed on the window frame 2. 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 9a and 9b is for the

Invention not necessary. For the present invention, one of the two drive rods 9a, 9b is also sufficient to lock 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 of which runs perpendicular to the faceplate 8 and is provided on the outside of the faceplate 8, the axis of rotation 12 of the actuating lever 6 being connected to a coupling pin 11a. On the other coupling pin 11 b engages a link 7, which is at a distance from the axis of rotation 12 of the

Actuating lever 6 is articulated thereon, the actuating lever 6 being secured against swiveling in the congruent position of the stub 8. 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 9a, 9b already mentioned above are guided so that they can move slowly, ie they are located - according to FIG a projection 23 is provided, which applies a continuously constant voltage to the actuating lever 6, which inclines the actuating lever 6 at a predetermined angle 29 from the handlebar 7. The permanent tension can, for example, also in the area of the pivot pin 30, by a spring, other energy accumulators 32 or also by the inherent elasticity of the actuating lever 6, which is made of a Stamped and bent part exists. 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

The exemplary embodiment is the energy storage device 15, 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 22a in FIG. 2b, with the spring element 19 thus prestressing and actuating the actuating lever 6 in the position of the closed position shown here the recess 17 and the detent 16 is held. 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 pivot-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 link 7, which in this Area in the direction of the actuating lever 6 is angled towards the faceplate 8, can reach through between the faceplate 14 and the handlebar 7 and changes into a partial opening position according to FIG. 3b.

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.

3b, the spring element 19 assumes its original shape, so that the spring element 19 is unloaded and I-shaped in this position.

Fig. 4 shows the closure device in a third position - the

Open position 24.

In this position, the drive rods 9a, 9b 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 11a, 11b in the elongated holes 10 or, depending on the embodiment, an elongated hole 10, one of which two axes of rotation 12, 35 is firmly 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. 5 shows a displacement of the actuating lever 6, according to which the actuating lever 6 is raised by lifting it away from the energy storage device 16 and thus away from the faceplate 8, the position of the actuating lever 6 shown in dash-dot lines showing the raised position and about - in FIG. 5a - a projection 36 of the energy storage device 15, which extends concavely in the direction of the actuating lever 6, assumes a window sash hinged according to FIG. 6a for the right or, as FIG. 6b shows, 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 22a, 22b 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, the receptacle 26 surrounds the U-web 25 and, on the other hand, one free leg 27a projects into the handlebar 7 and the other free leg 27b, which is designed as a round projection, engages through one of the two laterally offset cutouts 28 of the actuating lever 6. In the embodiment shown it is a window wing hinged on the right. In order to convert 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 pivot-proof position. Thus, the U-shaped 21 spring element 19 is released and rotated through 180 ° depending on the type of design. The free leg 27b engages in the cutout 28 of the actuating lever 6 on the other side.
