Description

The invention relates to a window fitting for a window a frame, a casement, which is mounted on the frame and in an opening direction from a closed to one open position is pivotable, with a sash on the sash with an interlocking actuating rod and on the frame a locking plate are attached, by means of which the closed Sash frame can be locked on the frame. Further The invention relates to a window with such a window fitting.

A window generally has a casement, which means Fitting on a frame pivoted or tilted is. There are usually locking elements on the casement (especially roller bolts) attached, which is connected to the fittings and in Locking plates on the frame are slidable. The locking elements are arranged in the area of a fold between the frame and the closed casement is formed.

The frame and the sash are subject to production contingent dimensional fluctuations. Furthermore, warp and twist they change during use due to thermal stresses and the weight of the glazing act on them. The fold between Frame and casement is therefore also used to compensate for Dimensional fluctuations and delay.

It is an essential feature of a window that it is in a attempted break-in offers sufficient security. Because burglars often shy away from making noise and the window pane smash, try the window on the window frame or casement to break up. Here, a burglar, for example using a crowbar or screwdriver, from on the outside between the frame and sash and lever the Casement inside. According to the quality assurance according to DIN V In 18054 a RAL-RG 607/3 quality mark is awarded for the fittings, if window attempts to lever with a lever torque of Resist 200 Nm or 300 Nm. Conventional locking elements one Windows are not enough to withstand these forces.

It is known, in addition to locking elements on the casement Arrange locking elements to ensure security against burglary increase. The locking elements are in the corresponding locking plates on Frame can be pushed or swiveled. The profile parts of the frame and the casement are for aesthetic reasons slim design and at the same time need sufficient stability also offer heavy heat and soundproof glazing to be able to wear. The place to arrange such additional Latch elements are therefore very limited.

With a security package from Unilux called "Safe-II" are additional to a locking mechanism in addition to roller bolts Mushroom cones attached. The roller bolts lock it Windows, while the mushroom cones also lock. The roller bolts and mushroom cones are each placed in a corner of the window and can by an actuating rod of the locking mechanism moved parallel to the profile parts of the casement become. The roller bolts are each in a bolt plate pushed. The roller bolts push the sash to Frame to increase the heat and sound insulation, and block the casement in this closed position. At the same time, the mushroom cones are pushed into a cone plate, in which her mushroom-shaped head hooks and additionally locked.

Door locks are known from the company Gretsch-Unitas GmbH, where locking hooks or locking bolts as locking elements on Engage the door leaf in the corresponding striking plates on the door frame. The door locks are relatively large and therefore the restricted space of a window unsuitable.

The invention has for its object a window fitting and to provide a window with such a window fitting, where the window fitting even in very tight spaces increased security against burglary on the casement offers.

Show on the casement due to the limited space known mushroom cones, e.g. that of the company's security package Unilux, slight play on the associated pin plate. At Windows that are not ideal manufacturing dimensions or slightly warped, the locking mechanism or canted jammed and the mushroom cone grinds on the cone plate. The window can no longer be locked easily. This problem has been able to use a standard sash lifter cannot be completely cleared out.

The intervention is in the case of door locks from Gretsch-Unitas GmbH the locking hook and locking bolt into the striking plates almost free of play. They also have locking bolts and locking pins smooth surfaces. Doors point in relation to windows a greater closing force, so that the small play of the locking elements does not cause problems. Such would be the case with windows However, door locks cannot be used, it would do the above Problem exist.

The invention further aims to provide a window fitting and to provide a window with such a window fitting at which the window fitting even with a not made to measure or warped windows can be easily locked and is lockable and at the same time sufficient or increased Offers security against burglary.

The task is according to the invention with a window fitting solved the features mentioned in claim 1. The latch is on can be pushed parallel to a profile part of the casement. The The bolt is about as wide as that in the locking area Designed half of his sliding path. The bar is therefore considerable wider than known bars, e.g. Mushroom cones. The bar attacks on a wide area on the frame and offers increased protection against burglary.

According to the invention, the task can also be performed by a window fitting be solved with the features mentioned in claim 2. The bolt is also parallel to a profile part of the casement slidable. However, the actuating rod can take three positions where the window is either blocked or can be opened. The bolt is like this in the sliding direction designed that its locking width is about a third of that Sliding path is. The bar is also considerably wider as known bars.

The object of the invention is further by a fixed fitting solved, in which the locked bolt in the opening direction from Locking plate has a distance of 5% or more of the rebate width, which is considerably larger than with known bars. The invention is based on the basic idea that the latch is merely in the opening direction of the casement, but not in the opposite direction this opening direction, offer security against burglary got to. Therefore, the locked latch does not have to be opposite rest or hook on the locking plate in the opening direction. The bolt can thus be designed so that it is in the opening direction uses the entire available space. The danger of one This causes the locking mechanism to get caught or jammed significantly reduced. At the same time, both the latch and the stop also be made of stronger material, so that the window fitting offers greater security against burglary.

These benefits can also be achieved by using the locked latch perpendicular to the opening direction of the transom or frame has a distance of 5% or more of the fold height.

The latch and the latch plate are advantageously designed as plates, which each have a slope inclined to the opening direction. The bolt and the locking plate can be made relatively be made of strong material and a relatively large width exhibit. The inclined flanks reach behind both in the opening direction, as well as perpendicular to it, so that the latch is a offers considerable security against burglary.

The bolt and the locking plate can also be used with advantage two hooks can be formed which e.g. very easy on the operating rod riveted and screwed into the frame. This means increased burglary protection with little effort achieved.

By the bolt and the locking plate each at least one tooth and the teeth are engaged when the closed Sash frame with locked bolt a bit in the opening direction is moved, the casement is perpendicular to its opening direction secured in the event of a break-in. Because the bolt and the locking plate can be made from relatively strong material are and can have a relatively large width, several Teeth are formed, which increases safety considerably offer against burglary.

The window fitting can be advantageous for a tiltable window be designed so that the actuating rod is linear between three points, a blocking point, an open point and a tipping point is movable and at the locking point of the bolt part of the locking plate faces, at the tipping point and open point, however Not. The locking plate then locks the locking bar only at the locking point. Such a latch can be tilted in the upper area Window be attached.

By locking the bolt at the blocking point and at the tipping point part of the Is opposite, but not in the open position, the bolt is only locked at the locking point and tilt point and can therefore be attached in the lower area of the tilting window his.

With reference to Figures 1 to 3 is a first embodiment of the window fitting. One in cross section Window 10 shown includes a frame 12 and one attached frame 14, each made of wood are. On wing frame 14 is a glass sheet 16 between two seals 18 and 20 taken. The seal 20 is by a Aluminum profile 22 held that attached to the sash 14 is. An aluminum profile 23 is also attached to the frame 12. The aluminum profiles 22 and 23 form together with the wooden casement 14 and frame 12 a window in composite construction.

The window 10 is shown in FIG. 1 in the closed position, where here the closed position of the casement 14 to the frame 12 is understood, in which the sash 14 corresponds to the ideal manufacturing dimensions, rests on the frame and is not exposed to any tension is that warp him from the ideal situation. The sash 14 is by fishing (not shown) on the frame 12th pivotally mounted and in an illustrated by an arrow X. Opening direction to open. The opening direction X extends in the closed position perpendicular to one Main plane or pane plane of the casement 14.

In general, the aluminum profiles 22 and 23 are on the outside attached to the sash 14 or frame 12 and the sash 14 lies on the inside of the frame, i.e. he is in Opening direction X to open inwards. One on the sash 14 arranged and sealing to the frame 12 sealing 24th compensates for manufacturing tolerances and warpage that of the casement 14 in the opening direction X relative to the frame 12 having. The seal 24 thereby prevents air flow between outside and inside.

Between the frame 12 and the sash 14 is a Cross-section rectangular fold 26 formed in the locking elements (not shown) can be arranged. The fold 26 has a fold width "b" in the opening direction X and in one of them vertical direction Z a fold height "h". The fold 26 serves to compensate for manufacturing tolerances and warpage in Towards Z.

In a groove 28 open to the fold 26 in the casement 14 is a Locking mechanism with an actuating rod 30 and a cover 32 attached. The operating rod 30 is relative to Sash 14 and cover 32 perpendicular to the direction Z and the opening direction X spanned plane and thus parallel to the profile part of the casement 14 shown an actuation path Y displaceable (i.e. perpendicular to the plane of the drawing of Fig. 1). On the operating rod 30 that is Blocking element (not shown), for example a roller pin, appropriate. When moving the operating rod 30, this engages Locking element in a locking plate (not shown) on the frame 12, blocks the sash 14 and urges it to the Window frame 12. The seal 24 thereby seals the window 10 from.

On the locking mechanism, a hook 34 is attached, which in the fold 26 protrudes and is open against the opening direction X. The hook engages in the locked position shown in Figs. 1 and 2 into a hook 38 on the frame by means of a screw part 42 is attached. The function of these hooks 34 and 38 is illustrated in detail in Figures 2 and 3.

The hook 34 is attached to the operating rod 30 in such a way that it moves with the operating rod 30. He can do it for example riveted to the actuating rod, welded or be screwed and by a in the cover 32nd protruding elongated hole protrude.

Moving the operating rod 30 along the operating path Y the hook 34 pushes from an open point O in the hook 38 reversed in the Z direction at the blocking point S. If the direction of actuation is reversed, there is a return movement of the hook 34. The hook 38 forms the locking plate for the Hook 34, which acts as a bolt. This is the catch 34 locked at blocking point S and not locked at open point O.

In another embodiment, the hook 34 may be one Tilting point K are pushed, at which the window can be tilted. The tipping point K is based on FIG. 3 to the left of the open point O. The hook 38 designed as a locking plate can be designed in this way be that the hook 34 is released at the tipping point K or is locked.

FIGS. 4 to 6 show a third embodiment of an inventive one Window fitting shown, in which the Frame 12 and the sash 14 of the window 10 as a wooden structure are trained.

An L-shaped stop plate 56 is in the fold 26 by means of two Screws 58 and 60 attached to frame 12. Through the cover 32 extends in the operating direction Y of the operating rod 30 an elongated hole 54. Two screws or rivets 50 and 52 protrude from the actuating rod 30 through the elongated hole 54. By means of the screws or rivets 50 and 52 is one in the fold 26 to the stop plate 56 reversed L-shaped locking plate 48 on the Actuating rod 30 attached. The locking plate 48 is by means of the actuating rod 30 is displaceable on the actuating path Y. and arranged with respect to the stop plate 56 so that it in the locked position in the opening direction X behind the Stop plate 56 comes to rest. The locking plate 48 and the Stop plate 56 have opposite in this position flanks inclined to the opening direction X.

As illustrated in Figures 5 and 6, this is the latch forming hook 34 and the locking plate 48 in their locked Position of the hook 38 forming a locking plate or the stop plate 56 spaced in the opening direction X by a distance "a". In relation to the fold width "b", the distance "a" 5% to 50%. In a further preferred embodiment the distance "a" 15% to 50% of the fold width "b". Especially a distance "a" between 25% and 50% of the Fold width "b" because of manufacturing tolerances and warping of the casement can be compensated particularly well.

The hook 34 or the locking plate 48 also faces the frame 14 or the stop plate 56 against the direction Z one Distance "c". The distance "c" is 5% to 40% of the fold height "H". Distances "c" between 10% and 30%, and particularly preferably between 20% and 30% of the fold height "H".

The latch plate 48 illustrates that one or more on the latch Teeth 62 can be formed. The teeth 62 engage associated teeth 64 of the stop plate 56 as a locking plate, if the sash moves in the opening direction X by the distance a is. The sash 14 can also have a certain dimension "dz" be moved in the direction Z, as illustrated in FIG. 6. A such movement of the sash 14 occurs when attempted is, the casement 14 based on the frame 12 by Moving or opening force from outside. The interlocking Prevent teeth 62 and 64 by friction or Positive locking a further movement of the casement 14 in the opening direction X and towards Z.
