Description

The invention relates to a locking device for a Window with the features mentioned in the preamble of claim 1 and a window with such a locking device.

A window generally has a casement, which means Fitting on a frame pivoted or tilted is. There are usually locking elements (especially roller bolts) on the casement attached, 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 sash 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 smashed, try the window on the window frame or casement break. 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, when windows attempt to lift with a torque of 200 Nm or withstand 300 Nm. Conventional locking elements of a window are not enough to withstand these forces.

It is known to also have 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 pushed into a bolt plate. The roller bolts push the sash to the frame, to increase the heat and sound insulation, and block the sash in this closed position. simultaneously the mushroom cones are pushed into a cone plate in which her mushroom-shaped head hooks behind and additionally locked. by virtue of everyone knows the limited space on the casement Mushroom cones on the associated cone plate slight play. at Windows that are not ideal manufacturing dimensions or slightly are distorted, 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 could also use a standard sash lifter cannot be completely cleared out.

Furthermore, door locks manufactured by the company Gretsch-Unitas GmbH known in which locking hooks or locking bolts Engage in the corresponding striking plates on the door frame on the door leaf. The engagement of the locking hook or locking bolt is almost free of play. Doors have a relative to windows higher closing force. Therefore, the little game does not lead to significant problems. Such door locks would be for windows however not usable, it would solve the problem described above consist. In addition, the door locks are proportionate large and therefore in a confined space of a window not suitable.

The invention has for its object a locking device for a window and a window with a locking device provide where the locking device even with a window that is not manufactured or warped to size locks easily and is sufficient at the same time or offers increased security against burglary.

GB 2 172 646 A discloses that comparable to a locking element and a stop Attack components when closed. Consequently the conventional approach described above is also used here, security components to provide a door lock so precise that it is locked in the Attack condition together.

The object is according to the invention by a locking device solved for a window where the locked bolt element in the opening direction to the stop a distance of 5% or has more of the fold width.

The invention is based on the basic idea that the locking element only in the opening direction of the casement, but not in the opposite direction this opening direction, against burglary security must offer. Therefore, the locked locking element does not have to be opposite the opening direction against a stop or behind hook. The locking element can thus be designed that it uses the entire available space in the opening direction and is arranged at a greater distance from the stop.

The risk of the locking mechanism getting caught or jammed is significantly reduced. At the same time, both Bolt element and the stop made of stronger material be so that the locking device is a higher one Has security against burglary.

The locking device is special against warping of the window robust if the locked locking element perpendicular to Opening direction to the frame or to the stop a distance of 5% or more of the fold height. This distance is possible It is sufficient if the locking element and the stop are only slight reach behind, since they are made of stronger material could be.

The locking element for locking is essentially advantageous slidable perpendicular to a profile part of the casement, so that it is moved from the casement to the frame and there with locked its locking width behind the stop. The locking width can be made significantly larger than this is the case with known mushroom cones. The security of the Locking device against burglary is thus significantly increased.

It is also advantageous if the locking element for locking can be swiveled out of the casement, since it becomes a profile part of the casement parallel movement of the locking mechanism can easily be implemented in a pivoting of the locking element. The locking element can also be far behind the stop of the frame.

The locking element can be locked particularly easily if it can be moved parallel to a profile part of the casement is. It can then, as is known from mushroom cones, in a simple manner be attached to the locking mechanism and still the above Have advantages.

It is also advantageous if a locking mechanism on the casement attached with a locking element (e.g. roller bolt) by means of which the closed casement can be locked, the locking element simultaneously by the locking mechanism can be actuated. The locking and locking function can be done by of a single component are carried out so that on the casement little space is required.

By the locking element and the stop each at least one Have a tooth and the teeth will engage when the closed one and locked sash a bit in the opening direction is moved, the sash is also perpendicular to secured its opening direction in the event of a break-in. There the locking element and the stop made of relatively strong material can be produced and can have a relatively large width, can be formed several teeth, which significantly enlarged Offer security against burglary.

The locking device according to the invention is particularly advantageous used in a window as it is only a small one Has space requirements.

With reference to Figures 1 to 3 is a first embodiment the locking device shown. One in cross section Window 10 shown includes a frame 12 and an adjoining casement 14, each made of wood are made. A glass pane 16 is on the casement 14 caught between two seals 18 and 20. The seal 20 is held by an aluminum profile 22, the 14 is attached. An aluminum profile is also on the frame 12 23 attached. 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 position. The sash 14 is on the frame 12 by rotating bands (not shown) pivoted 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.

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 in relation 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 (standard roller bolts or locking parts) (not shown) can be arranged. The fold 26 points in the opening direction X a fold width "b" and in a perpendicular to it Direction Z a fold height "h". The fold 26 also serves Compensation of manufacturing tolerances and delay in the direction of 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 displaceable parallel to the profile part of the casement 14 shown (i.e. perpendicular to the plane of the drawing of Fig. 1). On the actuating rod 30 is the locking element, for example a roller pin known as such (not shown) attached. 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.

To secure against opening in the opening direction X is next to the locking mechanism a locking device according to the invention trained with in the illustrated embodiment the actuating rod 30 cooperates. The function of this locking device is detailed in Figures 2 and 3 illustrated. A locking bolt 34 is in one as a locking element Bolt pocket 36 out. The locking pocket 36 is in a Fold 26 open recess of the sash 14 inserted. At the Frame 12 is a stop in relation to the slide bolt 34 Form of a locking plate 38 arranged. The locking plate 38 is fastened by means of screws 42 in a recess of the frame 12.

On the actuating rod 30, a bolt 40 is attached, the protrudes through an elongated hole 41, which in a side wall of the locking pocket 36 parallel to the direction of movement of the actuating rod 30 is formed. The pin 40 is by means of the operating rod 30 displaceable in the slot 41 by an actuation path Y.

In the slide bolt 34, a curved track 44 is excluded, which the Push bolt 34 penetrates in the direction X and along the actuation path Y extends. The cam track 44 points in the direction Z a rising and then a falling section on (Fig. 3), i.e. the rising or falling sections the cam track 44 are at an acute angle to the actuation path Y. The pin 40 engages in the cam track 44.

When moving the operating rod 30 along the actuating path Y pushes the bolt 40 along the ascending section the cam 44 the slide bolt 34 from the bolt pocket 36 and along the sloping section of the curved track 44 from the locking pocket 36 into the locking plate 38. When reversing the direction of actuation there is an analogous movement of the slide bolt 34. In this way the linear movement of the operating rod 30 parallel to a profile part of the sash 14 in one vertical movement of the slide bolt 34 implemented.

In Fig. 4 it is shown how the linear movement of the push rod 30 convertible into a pivoting movement of a pivot bolt 35 is. The pivot bolt 35 is by means of a bearing pin 46 pivotally mounted, which extends in the opening direction X. and in the section of the locking pocket remote from the locking plate 38 36 is arranged. In the swivel bar 35 is a recess trained cam track 44 into which the pin 40th protrudes. The cam track 44 has in the unlocked position of the pivot bolt 35 a rising towards the bearing pin 46 and a subsequent one parallel to the operating rod 30 Section on, cf. Fig. 4.

When moving the operating rod 30 along the operating path Y, the pin 40 slides in the cam track 44 and lifts thereby the swivel bolt 35 from the bolt pocket 36. The bolt 35 pivots in the locking plate 38, being counter to the direction Z can cover a considerable swivel path. The Swivel lock 35 therefore engages relatively far into the locking plate 38 on.

FIGS. 5 and 6 show a third embodiment of an inventive one Locking device shown in the the frame 12 and the sash 14 of the window 10 as Wooden structure are formed.

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 along the actuation path Y of the actuation 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.

As illustrated in Figures 1 to 6 as a whole, the the slide bolt 34 forming the bolt element, the swivel bolt 35 and the latch plate 48 in its locked position from the a stop plate 38 forming the stop or the stop plate 56 spaced in the opening direction X by a distance "a". Based on the fold width "b" the distance "a" is 5% to 50%. In a further preferred embodiment, the distance is "a" 10% to 40%. A distance "a" is particularly preferred between 15% and 35%, as a result of manufacturing tolerances and Warping of the casement can be compensated particularly well.

The locking element also faces the frame 14 or the locking pocket 38 against the direction Z at a distance "c". The Distance "c" is 5% to 40% of the fold height "h". Prefers distances "c" are also between 8% and 30%, and special preferably between 10% and 20%.

The slide bolt 34 and the locking plate 48 illustrate that one or more teeth 62 can be formed on them. The Teeth 62 engage in associated teeth 64 of the locking plate 38 or the stop plate 56 when the casement is in the opening direction X is moved by the distance a. The sash 14 can also a certain amount "dz" can be moved in direction Z, as in Fig. 2 illustrates. Such a movement of the casement 14 occurs when an attempt is made to frame the sash 14 to move the frame 12 by external force or open. Prevent interlocking teeth 62 and 64 a further movement of the casement by friction or positive locking 14 in the opening direction X and in the direction Z.
