Applicant: SIEGENIA-FRANK KG, Eisenhüttenstr. 22, 5900 victories 1 Closing plate for window and door locks or the like.

The innovation concerns a striker for window and door locks Od. Like. That has a partially cylindrical three-dimensional shape with a secant U mfangsabf lachung and directed transversely to the frame plane, the rebate surface of the fixed frame with its surface line penetrating blind hole of predetermined depth can be used and thereby the Umi gsflatung is flush with the rebate surface of the fixed frame, with a locking engagement in a form-fitting manner Flattened towards the open chamber of a housing and guided by means of a screw spindle mounted in the end wall of the housing is provided with a continuously adjustable slide.

A closing plate of this type is already known from DE-GM 74 02 626. It has the advantage that the on the rebate surface of the fixed Frame adjoining recess for accommodating them can be produced in a particularly simple manner, namely exclusively by a pitching movement of the milling cutter in the direction of its axis of rotation can.

Such closing plates are used in particular on such windows and doors, in which the frame-side functional parts of hinges, for example for turning, bottom-hung or top-hung sashes, but also the corner bearing and the scissor bearing of Tilt & Turn sashes have a pot-like shape and are in simple blind bores or milled blind holes can be used on the fixed frame, which penetrate the rebate surface of the fixed frame with their surface line.

While the hinges, corner bearings and scissor bearings of the concerned Design each have a specific design from the outset due to their intended use, locking plates for window and door locks must od. The like. Be matched to their construction and mode of operation, which differ from case to case, and consequently in correspondingly different ways Designs are manufactured and kept in stock. Especially for those strikers that require pressure adjustment for the window and door locks are supposed to allow, there is then a considerable effort, because a design that is as stable as possible in a limited installation space and backlash-free guidance of the adjustable bolt engagements guaranteed and still a smooth adjustment of the same over a long service life must be ensured.

The aim of the innovation is therefore for a closing plate of the initially Specify a spatial shape explained in more detail, which is dependent on the use of a few different individual parts Assignment to window and door locks od. Like. Different construction and function can be coordinated.

The solution to this problem is achieved according to the innovation essentially in that the slide forming the locking engagement with arms protruding backwards via its locking surface in guide rails arranged on both sides of the screw spindle in the chamber of the housing

grooves held and thus in the chamber of the housing either a locking engagement with opposite its secant-like circumferential flat recessed locking surface or a locking engagement can be used with the locking surface protruding from this secant-like U mfangsflachung.

Except for a housing that is identical in construction for all cases and one as well for all cases, identical screw spindles are required after the innovation, only two structurally different locking interventions or slides, in order to have adjustable locking plates for four different purposes. The latch engagement or Slider with a locking surface that is recessed in relation to the secant-like flattened circumference of the housing can be divided into two by 180 ° Insert mutually twisted relative positions in the chamber of the housing and with correspondingly different shapes of the Use locking surfaces at its ends facing away from each other to enclose differently designed Baskülriegel. The same striker but can also form the frame-side functional part for the joint-side center locks on windows and doors, one from the sash rebate Carry overhanging stationary bolt tongue. The different design of the locking surfaces at both ends of the relevant locking engagement or slider then offers the possibility of tuning by appropriately twisted installation of the same in the chamber of the housing different swivel radii of the engaging tongue protruding from the sash rebate.

If the locking plate is equipped with the bolt engagement or slide, the bolt surface of which is over the secant-like circumferential flattening of the housing protrudes, then it can not only be used in conjunction with window and door locks that are only used briefly have exclusive Baskül- or Kanteriegelschiebef, but

it can also be used in conjunction with the so-called locking pin window Use and door locks in which locking pins, which can be displaced by a connecting rod, protrude from longitudinal slots in a faceplate.

According to a further educational innovation it is provided that the housing of the closing plate is provided with support or screw-on flaps on both sides that adjoin the secant-shaped circumferential flattened area which are connected to one another at the rear end of the housing via a segment-shaped wall section and between them Wall section and the end wall of the housing limit the passage of the chamber associated with the locking engagement for the locking engagement.

It is also seen as an innovation that the chamber has an essentially cruciform delimited guide cross-section in the housing for the slide serving as a locking engagement, which is designed to be open towards the rear and corresponds in its dimensions to the slide or locking engagement with the smaller outline dimensions, while the larger in its outline dimensions Slide or latch engagement is provided on one side with a tongue-like extension, which in the area of the circumferential flattening of the Housing protrudes from the passage of the chamber.

It has proven itself in the context of the innovation if the slide or locking engagement with the small outline dimensions has at least one locking surface which tapers in a convex arc-shaped manner towards the end wall of the housing and towards the passage after its circumferential flattening, such that when the closing plate is arranged in the Pivot-axis side spar of a wing window or a wing door with a latch tongue projecting from the sash rebate essentially in the direction of the plane of the wing forms an automatically sailing in and out center lock.

Also the one present at the other end of the slide or latch engagement The locking surface can possibly have a convex arcuate course, but with a different arc radius and for flattening the circumference of the housing pointing position with a bolt tongue protruding from the sash rebate come into operative connection, which is movable on a correspondingly changed pivot radius around the hinge axis of the wing.

According to another development according to the innovation of a closing plate the slide or locking engagement with the larger outline dimensions in its section received within the chamber of the housing has a shape that corresponds to that of the slide or locking engagement with the smaller circumferential dimensions is at least similar. On the other hand the protruding from the passage of the chamber of the housing, tongue-like extension of the same in a position offset forward by the thickness of the housing end wall is formed on the slide or locking engagement. In the basic position of the slide or latch engagement therefore, the free end face is on the same plane with the outer boundary surface of the housing end wall.

According to the innovation, an apprenticeship after which the The end wall of the housing has a wedge-shaped tapering thickness towards the edge delimiting the secant-like peripheral flat, because this not only results in the tongue-like extension of the slide or latch engagement in the larger outline dimensions Transition area between the tongue-like extension and the guide section located within the chamber is sufficient retains large wall thickness, but also when installing the slide or bolt engagement with the smaller outline dimensions whose locking surface upstream inlet slope is formed.

For problem-free insertion of the slider or bolt engagement in the chamber of the housing, especially the larger ones

A chamber 7 is formed in the housing 2 from the rear, as shown particularly clearly in FIG of the housing 2 and its end wall 4 merges into an upwardly open passage 8, which can be seen in particular in FIGS. 2, k and 6.

The cross-shaped guide section of the chamber 7 has two upright legs 9 and 10 and two horizontal legs 11 and 12, wherein the horizontal leg 11 and 12 from the open rear side to k towards the end wall straight through, horizontal, upper boundary surface 13 or \ k , while its lower boundary surface has two horizontal sections 15 or 16 and 17 or 18 lying one behind the other in the direction from the open rear side to the end wall Ί. The front sections 15 and 16 of the lower boundary surface are higher than their rear sections 17 and 18 and merge into one another through an inclined step surface 19 and 20, as can be seen in FIGS. In alignment with the two axial planes of the cross-shaped guide cross-section of the chamber 7, the end wall k of the housing 2 according to FIG. 5 has a circular bearing passage 21 in which the front end 23 of a screw spindle 22 is rotatable but axially immovable.

The screw spindle 22 advantageously engages with a collar 2k in a neck 25 on the rear side of the end wall k and is axially fixed in the hole 21 of the end wall k by deforming its front end 23, for example by upsetting or flanging a countersunk head.

In the closing plate 1 according to FIGS. 1 and 2 is in the cross-shaped In the guide cross-section of the chamber 7, a slide 26 is inserted, which has a locking surface 27 running in a convex arc on the rear and thereby from its end lying in the lower leg 9 of the cross-shaped delimited guide cross-section of the chamber 7 to the end in the upper one Leg 10 of the same located end tapers, in which case the upper end of the slide 26 lies on a plane of movement, which is located slightly below the straight delimiting edge 6 of the segment-shaped wall section 5 and is wedge-shaped from bottom to top tapering surface area 28 of the secant Peripheral flat 3 on the end wall 4 is assigned.

The slide 26 is in control engagement with the screw spindle 22 via an internal thread 29 of an integrally formed neck 30 and has two laterally arranged arms 31 and 32 projecting backwards over its locking surface 27, which with the horizontally lying legs 11 and 12 in the cross-shaped guide section of the Chamber 7 are in guiding engagement. The arms 31 and 32 take on all support and management personnel who adjust themselves to the slide 26 as soon as this is acted upon via its locking surface 27 by a locking projection or a locking tongue entering through the passage 8 into the chamber 7.

In adaptation to the shape of the upper boundary surfaces 13 and 14 and the lower boundary surfaces 15, 17 and 16, 18 for the horizontal legs 11 and 12 of the cross-shaped boundaries Guide cross-section of the chamber 7 in the housing 2, the arms 31 and 32 also have corresponding support surfaces 33, 34 on their upper side as well stepped support surfaces 35, 36 and 37, 38 on their underside.

Of course, the arms 31 and 32 of the slide 26 only have such a length that they allow an adjustment of the slide by means of the

-U-

Screw spindle 22 within the housing 2 in its axial direction allow over a range of several millimeters without protruding over the back of the housing. The adjustment the screw spindle 22 is thereby possible that this at its front end with a tool engagement 39, for example a diametrical slot or a hexagon socket.

The one serving as a locking engagement of the closing plate 1 according to FIGS Slide 26 is designed so that it can be easily pushed axially from the open rear side into the chamber 7 of the housing. It could also be designed so that its convexly curved locking surface 27 to its opposite ends with different Curvature radii expire and are therefore twisted in two by 180 ° around the axis of its internal thread 29 for different purposes Layers can be inserted into the chamber 7 of the housing 2. In this case, either his two backwards protruding arms would have to 31 and 32 be formed straight through at their upper and lower boundary edges, or it would be necessary to the upper and lower boundary surfaces of the protruding arms 31 and 32 and the associated guide surfaces in the horizontal legs 11 and 12 of the cruciformly delimited guide cross-section of the chamber 7 to be designed accordingly in a stepped manner.

The closing plate 1 according to FIGS. 1 and 2 is particularly suitable for Use for windows and doors with sashes that are only close to and parallel to the edge relative to the fixed frame The hinge axis can be opened and closed, as is the case, for example, for rotary sashes, tilt sashes or even folding sashes. With such Windows or doors are often only installed in the vicinity of the corners axis-forming hinges or joints, while to achieve the necessary sealing over the between these hinges or

Joints lying length range away so-called center closers come into use. These then have latch tongues protruding essentially parallel to the plane of the sash on the rebate surface, which come into operative connection with the locking surfaces 27 of the frame-side closing plate 1 with a circular arc movement when the sash approaches its closed position. The closing plate 1 becomes this Purpose in a blind hole milling or blind hole of the fixed Frame used, which penetrates the rebate surface with its surface line. The sckanten-shaped circumferential flat 3 of the closes Housing 2 either flush with the rebate surface of the fixed frame or is slightly behind in parallel. For position alignment and attachment of the striker 1 to the fixed frame support or screw-on tabs 40 and 41 are provided on the housing 2 in the embodiment shown, which are attached to the secant-shaped Circumferential flattening on both sides of the passage 8 adjoining and are connected to one another at the rear end of the housing via the segment-shaped wall section 5. These support or screw-on tabs 40 and 41 lie against the rebate surface of the fixed frame and can be fastened there with screws.

Of course, the closing plate 1 according to FIGS. 1 and 2 also in connection with window and door locks their direction of movement emerge from the upper and lower rebate surfaces on the wing corners on the locking side.

As already mentioned above, the closing plate 51 has to 3 and 4 basically have the same structure as that according to FIGS. 1 and 2. In particular the housing 2 and that in the bore Screw spindles 22 mounted on its end wall 4 are identical in both embodiments.

However, the closing plate 51 according to FIGS. 3 and 4 is provided with a slide 42 serving as a locking engagement, which has larger outline dimensions than the slide 26 of the closing plate 1 according to FIGS Housing 2 received portion of this slide 42 is that of the slide 26 similar. However, this has a tongue-like extension 43 protruding from the passage 8 of the chamber, which is formed on the slide 42 in a position offset forward by the thickness of the end wall 4 of the housing 2, as can be clearly seen in FIG. Since the housing end wall 4 tapers in a wedge shape from bottom to top in the area of the secant-like circumferential delimitation 3, the tongue-like extension Wi can connect to the slide Wl with a sufficiently thick wall so that it also has high stability in its transition area to the slide.

The arms 31 and 32 protruding over the rear side of the slide Wl and the horizontal leg sections 11 and 12 assigned to them in the cruciform delimited chamber 7 of the housing are different with regard to the stepped configuration of their lower support surfaces 35, 36 and 37, 38 or their lower guide surfaces 15 , 16 and 17, 18 the installation of the slide Wl in the housing 2 is particularly beneficial. Since the slide Wl with its tongue-like extension Wi must be inserted under the straight boundary 6 of the segment-shaped wall section 5 at the rear end of the housing 2 through into the upper leg section 10 of the chamber 7 and then moved upwards out of the passage 8 of the same, can insert the slide Wl into the housing 2 only with a corresponding pivoting movement, as is indicated in FIG. 4 by dash-dotted lines. Here, the front end edges of the arms 31 and 32 laterally adjoining the slide 42 need to enter the
