Description

The invention relates to a locking plate according to the preamble of claim 1.

Fittings or are used to lock building windows and / or building doors Known closures that can be at least partially fastened in the window or door fold and have locking or locking elements, which via the transmission of Closure, for example via a connecting rod, between a closed state and are movable in a non-locking state and in the closed state closed door or with a closed window in a bolt opening Intervene with the striker plate, which is mounted on the frame in the fold there. Such a closure in its training as a drive rod closure is described for example in DE 297 02 182.

The closure elements can have a wide variety of shapes. Strike plates with closure elements designed as rolling pins are e.g. in FR-A-2 236 375 or described in DE-A-2 211 523. To increase the security against burglary are also closures with closure elements in the form of mushroom head cones used. Suitable locking plates for these closures are for example in the DE GM 92 16 213. also slide latches, Turnbuckle, hook bolt etc.

The known locking plates and their strikers are made of metal and have the disadvantage that they only very much in terms of shape and coloring are not adequately adapted to the respective frame or frame. Already one even a fairly appropriate color scheme requires a relatively expensive one Production method (additional edge smoothing, degreasing, painting with then drying). In addition, careful handling is to be avoided damage to the paintwork during transport, storage and assembly is required.

Also known are strikers (DE 295 08 590 U1), which are specially designed for Plastic windows or doors are intended and manufactured as a molded piece of plastic are. To be achieved with these known strikers, among others an easy one Assembly and a tight and smooth closing of the respective window or the respective door. A molded part made of plastic, however, does not offer the necessary Security against violent opening of the door or window sash.

The object of the invention is an inexpensive, consisting of a few individual parts and yet to create a very stable locking plate that is also optically optimal fits the cane or frame. A locking plate is used to solve this task trained according to protection claim 1.

In the invention, the locking plate is made as a molded part made of plastic, which the Striker made of metal, preferably made of steel. The latter at least forms that part of the bolt opening that the locking of the closure element in Closing state causes, and is at least on the visible surfaces of the locking plate, i.e. on those surfaces of the locking plate that are visible after assembly, from the plastic of the striker is covered and covered. By the invention Training, it is possible to use the locking plate in its color, but also in its outer shape and contour optimal in color and shape of the glare or Adjust the stick frame profile so that it does not look or only slightly Appearance occurs, or the striking plate consciously as optically prominent, however to develop an appealing design element in terms of shape or color. Despite the possibility of such a color and realizable with little effort Shape design, the locking plate according to the invention offers a high level of security for the closed windows or for the closed door.

In the figures, the three are perpendicular to each other for easier orientation extending spatial axes, namely the X-axis, Y-axis and Z-axis.

In the figures, 1 is the casement of a building window. The sash 1, the has the usual glazing, not shown, is in a floor or Frame 2 tilt and / or swivel provided. The sash 1 is off several lengths of a sash profile 1 'made, which at embodiment shown a plastic profile with several, by Stiffening webs separate cavities or chambers and with one Reinforcement profile 3 made of metal, for example steel.

The stick frame 2 is made from several lengths of a stick frame profile 2 ', which also has a plastic profile in the embodiment shown several cavities or chambers formed by reinforcing webs and with a reinforcing profile 4 made of metal, for example made of steel.

Among other things, the sash 1 a lock fitting or closure is provided with which the casement 1 locked in its closed position on the frame 2 can be. One of this closure is in the fold 5 of the casement 1 arranged drive rod 6 reproduced there on a guide rail 7 of the Closure in an axial direction perpendicular to the drawing plane of Figure 1, i.e. in the X-axis is slidably guided and carries a plurality of pin-like closure elements 8, which in the illustrated embodiment as a mushroom cone with a widened head 8 'are formed on a pin section 8 "and protrude beyond the fold surface 5.

On the fold surface opposite the fold 5 of the closed casement 1 9 'of the stick frame rebate 9 locking plates 10 are attached, namely at the illustrated embodiment, one locking plate 10 for each Closure element 8 such that in the unlocking position of the closure or the drive rod 6 of each closure element 8 in the direction of the longitudinal axis of the Drive rod 6, i.e. laterally in the X axis relative to the associated locking plate 10 is offset, while moving the drive rod 6 in the closed position Closure element 8 laterally in a bolt opening or recess 1 1 associated locking plate 10 is moved into it.

As FIG. 6 in particular shows, each locking plate 10 has two such Recesses 11 which on the upper side 10 'of the folding surface 8 facing away from the Closing plate 10 as well as on a transverse side running perpendicular to the X axis 10 "of the closing plate 10 is open. So that the mushroom cones Closure elements 8 with their widened head 8 'in the closed state each Can engage behind locking plate 10 in the recess 11, has each recess 11 in cross-sectional planes parallel to the Y-Z plane, i.e. perpendicular to X-axis and thus a T-shaped perpendicular to its longitudinal extent Cross-sectional profile, so that each recess 11 at the top 10 'a section 11 'of reduced width and including a section 11 "of greater width.

To continue the usual when moving the drive rod 6 in the closed state Tighten or tightly press the sash 1 against the stick frame 2 reach, each recess 11 in the area of the transverse side 10 "with one in the Wide widening enema. This enema is in section 11 " formed that the front 10 '' 'of the closing plate 10 closer side of the Recess 11 forms a ramp or inclined surface 12 which is perpendicular to the X-Y plane lies and their distance from the front 10 "'to the open end of the respective Slit 11 decreases. When moving the drive rod 6 in the closed state comes the respective closure element 8 with its head 8 'against the inclined surface 12 to the system and presses the further closing movement of the drive rod 6 Sash frame 1 in the closed position.

The closing plate 10 is also designed so that it is exactly in the fold of the Stick frame 2 fits and in the assembled state with its bottom 10 "" against Folding surface 9 abuts and continues with its front 10 "'flush with the Inner surface of the stick frame 2 or the stick frame profile 2 'lies, as in the Figure 1 is shown.

Furthermore, the closing plate 10 is on its underside 10 "" with one in the direction the X-axis extending and projecting over the underside strip-like Provided projection 13, which is in a mounted on the fold 9 of the Stick frame 2 engages groove 14 formed.

Adjoining the projection 13 is on the underside 10 "" in the direction of the X-axis extending groove 15, into which a groove 9 protruding strip-like projection 16 of the stick frame profile 2 when mounted Closing plate 10 engages. Between the groove 15 and the parallel to the front 10 "' lying back 10 '"" has the locking plate 10 on its underside 10 "" In the direction of the X-axis extending groove-shaped recesses 17 and 18, the serve in particular to save material. With the help of mounting holes 19 penetrating fasteners, such as fastening screws Closing plate 10 on the stick frame 2 in the area of the fold 9 there or on the Folded surface 9 'fixed. Here, the projection 13 engages in the groove 14, at the same time a locking lug 20 which on the front 10 "'side of the projection 13 is formed, a counter detent 21 formed in the groove 14 of the stick frame profile 2 ' engages behind and also the back 10 "" 'of the respective locking plate 10 against a fold surface 9 ″ of the fold 9 enclosing an angle with the fold surface 9 ′ is applied. This makes it possible when mounting the locking plate 10 before the introduction of the fastening means reaching through the fastening bores 19 to position on the stick frame profile 2 'and against Secure slipping. Furthermore, by engaging the projection 13 in the Groove 14 and by reaching behind the counter detent 21 with the detent 20 and through the flat contact of the back 10 "" 'against the fold surface 9 "a positive and particularly secure anchoring of the respective locking plate 10 in the fold 9 of the Floor frame 2 reached so that a violent opening of the sash 1st is at least considerably more difficult.

A special feature is also that the striker plate 10 at illustrated embodiment made of sheet steel by bending and punching Contains striker 22, which is substantially elbow-shaped, and with two legs 23 and 24. The striker 22 is in the plastic Closing plate 10 embedded, in such a way that the leg 23 in the Projection 13 extends and also in the groove 14 when the locking plate 10 is installed extends. The slightly Z-shaped angled leg 24 extends within the Closing plate 10 with a certain distance below the top 10 '. The striker 22 is provided with laterally open recesses 11a. Because the width of the Striker 22 in the direction of the X axis is smaller than the corresponding width of the Closing plate 10, the recesses 11a form the section outside the inlet 11 'of the respective recess 11. Furthermore, the striker 22 is in the area of Leg 24 provided with two openings 19a, which are part of the mounting holes 19 of the locking plate 10 are. In the leg 24 openings 25 are provided through which the plastic of the closing plate 10 embedding or enveloping the striker 22 passes through and thus connecting or embedding the striker 22 in improve the locking plate 10.

In sections 11 ', the edge of the respective recess 11 is thus separated from the Edge of the recess 11a of the striker 22 is formed. Only here is the illustrated embodiment, the striker 22 free. Otherwise this is Striker completely encased in the plastic of the striker plate 10. in the In the closed state, the respective closure element 8 lies with its pin-like Section 8 "against the edge of the recess 11a in the striker 23 and engages behind the closing piece 22 at the edge of the recess 11a with the head 8 '.

The advantages of the locking plate 10 include in that by using the Plastic attractive shapes and colors for the locking plate 10 and their Visible surfaces are possible, in particular an adjustment in shape and color is also required the stick frame profile 2 'possible. Furthermore, the closing plate 10 in its Adapt the shape to the shape of the stick frame profile 2 'or to the fold 9 such that optically disruptive and difficult to access or difficult to clean surfaces or Areas on the assembled locking plate 10 and its surroundings are avoided.

In particular, the underside 10 "" and the back 10 "" 'of the closing plate 10 can be optimally in a particularly simple manner on the folding surfaces 9 'and 9 "and adapt to their profiling. The bottom 10 "" and others to save material The provided recesses 17 and 18 are 10 when the locking plate is installed completed, so that penetration and accumulation of foreign matter, for example dirt is not possible.

It is also particularly advantageous that the through the leg 23 of the striker 22 reinforced projection 13 engages in the groove 14, so that this makes a special secure anchoring of the striking plate 10 on the stick frame profile 2 'is reached. A Another special feature is that in the insertion or infeed area the one Plastic surface formed inclined surface 12, the system for the respective Closure element 8 or its head 8 'forms, while only at the end of the Closing movement of the respective closure element, i.e. then when pressing the sash 1 against the stick frame 2 has already taken place, the respective Closure element 8 in the part of the recess formed by the recess 11a 11 moved into it. This will press the sash 1 against the Stick frame 2 by sliding the closure elements 8 made of metal on the Inclined surface 12 made of plastic.

The locking plate 10 and thus the respective striker 22 are mirror-symmetrical to a central axis M running in the direction of the Y axis trained so that one and the same striker 10 for use on the right or can be provided to the left of the respective closure element.

The invention has been described above using an exemplary embodiment. It it goes without saying that numerous changes and modifications are possible without that this leaves the inventive idea on which the invention is based. For example, it is also possible to use the respective locking plate 10 with others Closure elements, for example together with closure elements use that are designed as pins, bolts or rollers. Furthermore it is possible to use the locking plates 10 on building window doors.

In principle, however, other designs are also conceivable in which the Bolt openings are not formed by slot-shaped recesses 11, but of other openings into which the closure or Engage locking elements of the fitting or lock used. In these versions too, the respective locking plate is made of plastic, in which a striker made of metal, which the respective bolt opening or forms part of this bolt opening, is completely embedded.
