Description

The invention relates to a fitting according to the preamble of claim 1. In particular, the invention relates to a closure device with an actuating rod arranged on the wing, which has a drive rod which is displaceable down to lower the wing by means of an actuating handle.

The lowering causes due to the inherent weight of the wing therefore a sealing closing the wing to the frame.

As a rule, liftable wings are additionally adjusted after lifting, in particular shifted to the side. They thus give, for example, a passage opening for a door. In the closed position, the wing must be sealed as possible against the fixed frame. For this purpose, it is od with sealing strips. Like. Equipped that abut with lowered wings at corresponding mating surfaces of the fixed frame. Accordingly, not only at the top and bottom, but also at the two longitudinal beams such sealing strips. If the wing is merely raised, the upper and lower seals, but not the lateral vertical seal, are released. If this wing is to be lowered again, the friction of the seals counteracts the lowering movement. With a light and high wing, this friction can cause it to counteract the lowering movement in such a way that the wing is not lowered or at least not completely lowered. At the end of the lowering movement, the transverse gaskets would also have to be pressed on.

To avoid this condition is through the DE 299 20 094 U1 a device has become known which causes a forced lowering of the wing. It consists essentially of a sliding element with a liftable, but preferably also movable wing of a window or a door and with a guide rail. In this case, there is an actuating linkage on the wing, which has a drive rod which is displaceable down to lower the wing by means of an actuating member. The fitting has a closure device which is detachable with the actuating linkage and has a drive rod portion, which is opposite to the drive rod of the actuating linkage is movable, wherein on the drive rod portion, a bolt is provided, which is in the closed position in engagement with a locking engagement and abuts against a contact edge of the locking engagement, wherein the locking engagement is directly associated with one of the guide rails.

In order to achieve an increased burglar protection with simultaneous forced lowering of the wing, a lowering device is in the embodiment in engagement with a locking engagement, which also forms a lock in the direction of displacement. Due to the requirements to effect locking while forced lowering, additional locking mechanisms are required in this fitting variant to secure the wing against displacement and to increase the burglary protection. The known design variant, which requires additional units, proves to be costly and demanding in the assembly by means of large component costs.

A fitting of this kind is likewise by the WO 2009/116843 A2 known. The known device in this case has a fitting of a sliding wing of windows or doors, in which upon actuation of an actuating handle of the movable wings for opening in a parked position of an adjacent wing or a fixed field is movable.
For closing the displaceable wing on the frame, the actuating handle has a pivot bolt, which is set in a rotational movement with actuation of the wing when striking the frame and engages in a frame arranged on the latch engagement.

Since it is in the known fitting exclusively to a sliding and non-liftable sash of a window or a door with subsequent displacement, an automatic lowering device is not realized. Furthermore, the closure device proves to be expensive to manufacture and is therefore costly. In addition, the locking elements are visible in the open state projecting on the wing, which adversely affects the appearance and represents a possible risk of injury when passing through the opening of a door or even when cleaning.

Moreover, from the DE 33 45 174 C2 an adjusting device has become known which can be used in windows or doors with lifting-sliding sash. This can be installed at any height on the closure side, vertical actuating linkage and causes next to a forced lowering of a stuck in the raised position during the closing of the wing at the same time also a locking thereof in the closed position. This is a stop by a bolt tongue of a bolt tongue closure formed, which has exclusively a hinge connection with the actuating linkage, which are assigned stationary on the sliding leaf guide curves as guide elements, wherein a counter-stop on the frame-side strike plate is arranged.

From the known device, no additional night ventilation device is apparent.

Furthermore, goes from the KR 200397177 Y1 a fitting with a sliding wing, which has a closure device. With actuation of an actuating handle while an arranged on the wing actuating linkage comprising a pivotable locking element, the sliding leaf to the frame in a sliding or locked position can be transferred, wherein the pivotable locking element engages in the locked position in a frame arranged on the closing plate.

The invention has for its object to provide a device for facilitating and assisting in the operation of the window or the door of an open storage position of a liftable, preferably movable wing in the closed position with increased burglary protection, as well as a night ventilation of the wing to the frame, which is inexpensive and which can be mounted and adjusted in a simple, fast, safe and precise manner with little installation space, with all possible variants being covered.

To solve this problem, a fitting of an at least liftable and movable wing of a window or door, provided with a running rail, wherein the vertical wing spar within a fitting groove of the wing, an actuating linkage is located, which has a drive rod for lowering the wing by means of a Actuator is displaced downwards, and transmits the displacement on at least one coupled carriage via a corner drive.

In this case, the fitting has a closure device which is fastened by means of a housing to the actuating linkage within the fitting groove and via a guide member is detachable with the actuating linkage, wherein the guide member is movable with actuation of the drive rod of the actuating linkage and a controlled on the guide member of a driver guide and on the housing of the closure device via a pivotally mounted pivoting latch of a concealed in the housing located within the actuating linkage opening position opposite to the direction to lower the wing into a free field of action of a closed position transferred, wherein a free end of the pivot bolt in the transition to the closed position with a on the Fastened frame, the bolt engagement arranged pin engages behind engages, wherein the locking engagement with a virtually flush mounted on the frame latch plate with one Has cutout for a passage of the pivot bolt, and forms a gap opening position with engagement of the free end of the pivot bolt in a clearance between the pin and the latch plate clearance.

Advantageously, the housing of the closure device is formed of two symmetrically ausgestaltenden housing shells, wherein the longitudinal wall of at least one housing shell with a longitudinal opening of the housing shell parallel to the wall arranged web on the surface of the housing shell forms the guide for the guide member. The design requires no further to guide the guide member forming member and is formed in the length so that the lifting movement of the guide member is completely and the pivoting bar almost completely hidden in the housing integrated. As a result, possible contamination that affect a smooth and desired movement can be excluded, so that the life of the construction is increased.

For ease of design and connection during assembly, the housing shells are preferably non-positively connected via a rivet connection as a one-piece component with the housing. Means for attachment to the housing allows in an advantageous and simple manner the positive and / or non-positive attachment to the actuating linkage. Due to the simple design and installation of the closure device to the actuating linkage, one or more closure devices are to be attached as needed to the actuating linkage.

A compact, smooth and almost play-free adjustment of the movable components of the closure device is achieved in that the housing shell forming walls, so that the longitudinal side wall forms an inner space between the housing shells, wherein the distance from the respective material thickness of the guide member and the pivot bolt in the motion-coupled installation state. By this embodiment, no additional, forming the distance components are required.

A light and stable coupling of the musculoskeletal system of the closure device to the actuating linkage is achieved in that the guide member from the opening of the housing in the direction of actuating linkage projecting has a driver which is positively coupled with a section of the drive rod of the actuating linkage.

That the pivot bolt has at the pivot point on both sides projecting pins, which are rotatably mounted in a bore of the housing shells, proves to be essential Facilitate assembly. In addition, can be determined by the simple production of the bore precisely the pivot point of the pivot bolt, which proves to be advantageous in the transition from the open position to a closed position with pivoting the pivot bolt in the locking engagement in that a readjustment of the closure device in compliance with the installation specifications is unnecessary.

A particularly advantageous feature when reaching the closure position, but especially when reaching the gap opening position is that the pivot bolt on the side directed towards the guide part has an L-shaped coupling element which is received by the driver guide and in the extended gap or closure position of the pivot bolt through the L-shaped form of the cam guide in positive engagement with the L-shaped coupling element prevents manual rotation. The release of the gap opening position is achieved only via the operating handle with transfer to the actuating linkage. Opening by unauthorized manual intervention on the closure device can not be achieved due to the positive engagement of the pivot bolt to the locking engagement.

A further advantageous embodiment provides that the free end of the pivot bolt is formed like a hook, and extends in a radius which presses the wing when transferring into the closed position against the frame and holds. To achieve a, sealed by the sealing strips arranged on the wing closure position, and that the wing itself lowers in non-independent lowering by its own weight, which is caused by the course of the backdrop. In addition, both a contact pressure and a forced lowering of the wing is achieved to the frame.

To achieve a small constructive housing of the closure device, which has an advantageous effect on the cost of the actuating linkage, the free ends of the pivot bolt are preferably formed around the pivot point arcuate or at least extending in a radius. This has the advantage that the housing can be made narrower and the engagement depth of the locking engagement for the pivot bolt can be reduced. Depending on the design of the window or the door to be made cutouts on the wing and / or on the frame for receiving the closure device and the locking engagement, are easy to design with low material processing.

An increased anti-burglary protection and improved optics is achieved in that the engagement of the pivoting bolt with the pin in the closed position and the engagement of the pivoting bolt between the pin and the locking plate in the gap opening position is concealed by the locking plate. The concealed arrangement in operative connection the closure device offers a burglar no approach of a tool. Even with the intended gap opening position is given by the flush design of the latch plate to the frame and the hidden position of the engagement of the pivot bolt in the locking engagement increased burglary protection.

Simple in the production and thus cost, is made of an angled band material locking engagement, wherein the angled perpendicular to the base plate, a U-forming plates produce the receptacle for the pin and connect the pin non-positively via a riveted joint. Due to the one-piece design of the locking engagement receives a high strength and holds loads, for example, in the event of burglary.

A smooth and low-noise pivoting of the pivot bolt in the arranged on the bolt engagement pin is achieved in that the pin has a roller which is rotatably mounted between the plates. Furthermore, the outer edges are rounded off on the pivot bolt, at least in the engagement region of the latch engagement, wherein the distance between the plates of the material thickness of the pivot bolt is adjusted.

To compensate for possible production inaccuracies, for example in the manufacture of the window or the door or during assembly of the fitting, a simple adjustment device is provided on the bolt engagement, which allows a continuous readjustment for the pressure from the wing to the frame. For this purpose, the locking engagement and a frictionally arranged on the frame mounting plate by means of an adjusting device are horizontally connected in the direction of displacement of the wing against each other slidably. By actuating the adjusting device, the distance between the mounting plate and the locking engagement can be adjusted.

For ease of design and maintaining a lasting high resistance to burglary adjustment consists of a mounted on the mounting plate threaded spindle, which is rotatably connected by means of the thread on the base plate of the locking engagement, and on the mounting plate on both sides of the threaded spindle spaced guide pin has concentric record leading holes in the base plate leading, with a tool on the threaded spindle having tooling allows a continuous adjustment of the distance between the mounting plate and the locking engagement.

In addition, it has proven to be advantageous to the function, installation and cost of the fitting that the closure device is independent of the fitting on the actuating linkage of the window or door mountable. Depending on the size and weight of the window or door, regardless of the fitting, the closure device can also be mounted several times on the actuating linkage in order to increase the tightening force and the resistance to burglary, if necessary.

In a fixed frame 1, a wing 2 in the direction of the arrow 3 can be raised and then displaced in the direction of arrow 4, wherein the arrow 4 symbolizes the opening direction. The lifting takes place in a known manner by means of a handle formed as a handle 5, which is pivoted for this purpose in the direction of the arrow 6 of the rotational movement. The rotational movement is transmitted to a drive rod 8 via an actuating linkage 7 of known design arranged in a fitting groove 20. The mounting rod 7 is also coupled in a known manner via a lower corner drive 9 with a front carriage 10. A connecting rod 11 leads to a second, not shown rear carriage. The Fig. 1 The drawing shows a window or a door with a fixed frame 1 and a fixed mounted not shown wing or fixed door panel. In addition, the window or the door is equipped with a movable wing 2. Via a rotary movement 6 of the actuating handle 5, the drive rod 8 is moved in the direction of the arrow 12 in the sliding direction upwards. This causes a displacement of the carriage 10 relative to the lower end of the wing in the sliding direction of the arrow 13. A switched between the carriage 10 and the lower wing end known thrust device, for example with tabs or lifting cams, simultaneously causes the lifting of the wing 2 in the direction of arrow 3 of the lifting direction the carriage 10 and the fixed frame. 1

The wing 2 is sealed at its lower end, for example via two embedded in the lower cross member sealing strips 14 and 15 relative to the fixed frame 1, said sealing strips 14, 15 are pressed sealingly in the embodiment of the horizontal leg of a running rail 16. Upper sealing strips 17 and 18 are pressed at lowered wing 2 at the associated profile end of an upper guide rail 19. If the wing 2 is initially only raised, that is shifted at its level, although the lower and upper sealing strips 14, 15, 17 and 18 are released, but the sealing strips remain on the Vertical beams under tension. Accordingly, both the lifting and the lowering of the wing 2 in pure lifting-lowering movement within the wing plane with a correspondingly strong friction is connected. The friction can be so strong that a high, narrow and light wing does not lower itself on release of his Absenkhubs alone under its own weight. Furthermore, narrow and light wings also follow in the closed position Fig. 1 to 5 the ability to lift the wing 2 and leverage accordingly. To counteract a possible Aushebeln, but at the same time all variants according to Fig. 11 to design with increased burglary protection at the same time forced lowering, the closure device according to the invention 21 is mounted on the closing side upper and lower wings 2, which are designed depending on the design variant intended latch engagement 22.

Essential elements of this fitting are the already mentioned and the components usually described below, such as the existing on the closing side wing vertical member 23 actuating linkage 7 with the drive rod 8, a locking engagement 22, and finally Fig. 3 to Fig. 8 the actuating device 7 preferably has at its upper and lower ends in the drive rod 8 a cutout 43 which is in a positive connection with a catch device 21 arranged in the driver 42 in a positive connection, whereby the Hub transmission on the closure device 21 takes place.

To Fig. 2 the fitting has a closure device 21, which is fastened by means of a housing 26 to the actuating linkage 7 within the fitting groove 20, and via the guide member 24 can be coupled to the actuating linkage 7. The guide member 24 is movable with actuation of the drive rod 8 of the actuating linkage 7 and transferred to the guide member 24 controlled by a driver guide 27 and rotatably mounted on the housing 26 of the closure device 21 via a pivot point 28 pivot bolt 29, from a hidden in the housing 26 within the actuating linkage 7 located opposite to the direction for lowering the wing 2 in a free operating field 30 of a closure position.

For this purpose, a free end 46 of the pivot bolt 29 on the transition to the closed position after Fig. 3 to 5 with a mounted on the frame 1, the locking engagement 22 arranged pin 32 engages behind. The locking engagement 22 has a locking plate 62 arranged almost flush with the frame 1 with a cutout 63 for a passage through the pivoting bolt 29. With engagement of the free end 46 of the pivot bolt 29 in a free between the pin 32 and the locking plate 62 distance 64 is a Gap opening position formed. The latch plate 62 is after Fig. 5 or 8th connected by means of fastening screws 71 to a mounting plate 55. But it is also possible to attach the latch plate 62 directly to the frame 1.

The housing 26 of the closure device 21 is made of two symmetrically ausgestaltenden housing shells 35, 36 after Fig. 3 and after Fig. 5 formed, wherein the longitudinal side wall 37 of the housing shells 35, 36 with a longitudinal opening 38 of the housing shells 35, 36 parallel to the wall 37 arranged web 39 at least on a surface 40 of the housing shells 35, 36 forms the guide for the guide member 24. The embodiment requires no further to the leadership of the guide member 24 forming component and is formed in length so that the lifting movement of the guide member 24 is completely and the pivot bolt 29 almost completely hidden in the housing 26 is integrated.

The housing shells 35, 36 are frictionally connected via a rivet connection as a one-piece component with the housing 26. For this purpose, the housing shells 35, 36 after Fig. 3 projecting rivet pins 58 and through holes 59 on.
Corresponding means 56 for attachment to the housing 26 allow the positive and / or non-positive attachment to the actuating linkage 7. The means 56 is an opening through which the closure device 21, for example by means not shown dowel pins on a forend profile 25 after FIGS. 9 and 10 transversely to the direction of movement of the closure device 21 movable components and that of the actuating linkage 7 is fixed and secured, for example, by riveting. Due to the simple design and installation of the closure device 21 to the actuating linkage 7, one or more closure devices 21 are attached to the actuating linkage 7 as needed.

The free space for almost play-free movement of the guide member 24 and the pivot bolt 29 after FIG. 3 and FIG. 4 in the housing 26 of the closure device 21 is provided by the fact that the housing shells 35, 36 having walls, consisting of the longitudinal side wall 37 and the further sheathing walls, an inner space 41 between the housing shells 35, 36 forms, wherein the distance 41 from the respective material thickness of the guide member 24 and the pivot bolt 29 in the motion-coupled installation state results. Further distance-forming components are unnecessary by this type of design.

The musculoskeletal system of the closure device 21 is coupled with the actuating linkage 7 after being coupled Fig. 3 by an on the guide member 24 from the opening 38 of the housing 26 in the direction of actuating linkage 7 projecting driver 42, with the Section 43 of the drive rod 8 of the actuating linkage 7 is positively coupled. In this embodiment, the driver 42 is rectangular in cross-section, since the guide member 24 made of a strip material, the shape of the driver 42 already pretends. But there are also other forms of the driver possible.

To Fig. 3 is at the pivot point 28 of the pivot bolt 29 on the visible side a projecting pin 44 is arranged, but also on the non-visible side opposite lying also protrudes. The projecting pin 44 are mounted to rotate in a bore 45 of the housing shells 35, 36 almost free of play.

Upon reaching the gap opening position after FIG. 6 to FIG. 9 , The pivot bolt 29 is connected via the gate 31 and the locking engagement 22 via the pin 32 completely positive manner. The pivot bolt 29 has on the side directed towards the guide member 24, an L-shaped coupling member 45 which is received by a cam guide 27, wherein in the extended closed position of the pivot bolt 29 by the L-shaped form of the cam guide 27 in positive engagement with the L-shaped Coupling 45 prevents manual rotation. Thus, the wing 2 is securely held to the frame 1 in the closed position and in the gap opening position. The release of the closing or gap opening position is only achieved via the operating handle 5 with carry on the actuating linkage 7. Opening by unauthorized manual intervention on the closure device 21 is not possible due to the positive engagement of the pivot bolt 29 to the latch engagement 22.

The free end 46 of the pivot bolt 29 after Fig. 3 and Fig. 6 is formed like a hook and runs in a radius. Due to the simple shape of the wing 2 is pressed and held against the frame 1 during transfer into the closed position. In addition, it is achieved by the circular profile of the free end 46, that even with non-independent lowering of the wing 2 by its own weight due to friction of the arranged sealing strips on the wing 2 to the frame 1 in the closed position both a contact pressure and a controlled forced lowering takes place.

As after Fig. 8 shown in dashed contour of the pivot bolt 29 are to achieve a small constructive housing 26 and thus the closure device 21, the free ends 46, 47 of the pivot bolt 29, preferably around the pivot point 28 arcuate or at least extending in a radius formed. With less required space of the movement mechanism, the housing 26 can be made narrower, so that even with adaptation of the pivot bolt 29, the engagement depth of the locking engagement 22 can be reduced. Depending on the version of the window or the door are to be made recesses on Wing 2 or on the frame 1 for receiving the closure device 21 and the locking engagement 22 with low material processing easy to make.

A security against burglary and an optical advantage of the closure device 21 are after FIGS. 3 and 5 can be seen in that the engagement of the pivot bolt 29 with the pin 32 in the closed position, and after Fig. 6 to 8 the engagement of the pivoting bolt 29 between the pin 29 and the locking plate 62 in the gap opening position is concealed by the latch plate 62. The material of the latch plate 62 can be selected according to the requirements of a resistance stress. The retrofitting or replacement of a locking plate 62 in the already installed state can be easily made on the basis of the type of attachment.

The locking engagement 22 is made of a metallic strip material, wherein, for example, after Fig. 3 the angled plates 49, 50 extend at a right angle to the base plate 48. The supporting plates 49, 50 form the base plate 48 a U-shape and take through arranged at the respective free ends holes on the pin 32, which is a non-positive connection, preferably a rivet connection with the plates 49, 50 in frictional connection. Due to the one-piece design of the locking engagement 22 receives a high strength and holds loads, for example, in the event of burglary.

A smooth and low-noise pivoting of the pivot bolt 29 in the arranged on the latch engagement pin 22 is achieved in that the pin 32 after Fig. 3 and Fig. 6 a roller 51 which is rotatably supported between the plates 49, 50. The roller 51 may be made of a plastic material or of a metal. In addition, the pivot bolt 29 is rounded at least in the engagement region with the locking engagement 22 at the outer edges 57. Preferably, the distance 52 between the plates 49, 50 of the material thickness of the pivot bolt 29 is adjusted and allows a smooth pivoting into the locking engagement 22nd

To compensate for possible manufacturing inaccuracies, for example in the manufacture of the window or the door or during assembly of the fitting, a simple adjusting device 65 is provided on the bolt engagement 22, which allows a stepless adjustability for the pressure from the wing 2 to the frame 1. These are after Fig. 5 and 8th on the side directed toward the vertical wing spar 23 of the locking engagement 22 and a frictionally arranged on the frame 1 mounting plate 55 by means of an adjusting device 65 horizontally in the direction of displacement of the wing 2 against each other slidably connected. With actuation of the adjusting device 65, the distance between the mounting plate 55 and the Set latch engagement 22.

It insists Fig. 5 and 8th the adjusting device 65 from a mounted on the mounting plate 55 threaded spindle 66 which is rotatably connected by means of the thread 67 on the base plate 48 of the locking engagement 22, and on the mounting plate 55 each on both sides of the threaded spindle 66 spaced guide pin 68 has concentrically having holes 69th the base plate 48 lead leader, with a stepless adjustment of the distance between the mounting plate 55 and the locking engagement 22 via a threaded spindle 66 having tool engagement 70.
