Description

The invention relates to an additional lock for wings of doors, windows or the like.

An additional lock with the aforementioned features is out the German utility model 93 10 560 known. The slide bolt this additional lock is only translational movable, so that it can occur especially with larger air gap can that the wing violently relative to the frame can be moved in the frame plane, so that the slide bolt and the striking plate disengage.

Additional locks with swivel bolts are also known, their swivel bolt axes near the rebate side Front edge of the wing are arranged. The swivel bolts are because of the folding space and because of the required Depth of engagement comparatively long, so that in the frame a correspondingly long engagement slot is required which brings with it corresponding instabilities. Moreover is a comparatively complex actuation mechanism required for the swivel bolt.

A lock is known from FR 45 462 A, in which a Bolt enters a striking plate and has a slide, the one above slanting slots vertically in the top of the Tie arranged hook can move that into the Insert the striking plate. The slide is operated by key. As a result, the known lock is not for one application suitable in connection with espagnolette fittings.

In contrast, the invention is based on the object an additional lock with the features mentioned above improve that his slide bolt a violent opening of the Wing in particular by moving the sash in the wing plane prevented.

This object is achieved by the features of claim 1 solved.

It is important for the invention that a spreader is provided, which acts on a hook of the slide bolt. However, this is only applied after the slide bolt provides a bolt feed bridging the rebate space has experienced, during which he without any pivoting movement out of the lock and into the striking plate has been. This ensures that the slide bolt in conventionally adjusted by the espagnolette fitting can be, namely by deflecting the drive rod fitting originating adjustment force from the vertical in the horizontal. It is not necessary to already be inside means of the additional lock or within a lock housing to provide for the hook to act behind it to move the striking plate. In this respect there is one simple design of the additional lock.

To the additional lock in the area of the application of To form a sliding bolt through the connecting rod in a simple manner, it is provided that the drive rod on a curved plate attacks that parallel to the connecting rods in a lock housing is guided and has at least one inclined slot, in which engages a guide pin acting on the slide bolt. The curved plate enables simple control of the backdrop for the guide pin when it's off the drive rod is guided vertically in the lock housing.

A configuration of the additional lock with regard to the design of the spreader is achieved if the slide bolt is relatively movable in the bolt feed direction Slider and striking plate side at least one hook has, in the case of movements relative to the slide bolt of the slider is loaded transversely. The relative mobility between the slide bolt and slide allows To transfer adjusting forces from the slider to the hook or hooks, to move them behind the striking plate so firmly. With this configuration, it is not necessary that Strike plate with regard to the spreading of bolt parts train in a special way. The design described above the additional lock is therefore especially for such Frame profiles suitable with particularly simple Strike plates are to be equipped, or where one a simple slot in a wall of a hollow profile is sufficient the wing is facing. Maybe even at all no striking plate necessary.

The above-described design of the additional lock can be further developed in that the slide from The slide bolt is guided in the bolt feed direction and with a Cross pin into the slanted slot of the curve plate parallel oblique slot engages, which the cross pin at in the striking plate is inserted End section the relative movement of the slide to the slide bolt certainly. By guiding the slide in relation to Pushbolt results in an axially parallel or coaxial arrangement between slide and slide bolt, so that both accordingly can be assembled radially positively. The slide is actuated by the cross pin a diagonal slot in the curve plate, which is the diagonal slot for the guide pin of the slide bolt is parallel. Consequently the slider and slide bolt will be the same length advanced as the slant slots are the same. A deviation of the two oblique slots results in their End section, so that different relative movements accordingly are carried out by sliders and slide bolts, to perform the hook movements described above can.

The additional lock can be developed so that the the guide pin acting on the slide bolt directly on the Push bolt or attached to a slide bolt carrier and through the oblique slot of the curve plate into one Horizontal slot of the lock housing engages. Becomes the guide pin attached directly to the slide bolt, this results in a correspondingly structurally simple training. Will the Guide pin, on the other hand, attached to a slide bolt carrier, So the structural effort is higher, but can be thus more expedient, for example more massive constructions manufacture that increase the security against burglary accordingly. The passage of the guide pin through the oblique slot of the Curved sheet in the horizontal slot of the lock housing ensures horizontal guidance of the slide bolt with simple constructive means.

The additional lock can be designed so that the hook are provided with oblique slots in the actuating pins of the slider.

To secure the position of the slide bolt in its entirety To reach the locked position, the additional lock be designed so that at least the guide pin with the slide bolt pushed into the striking plate receiving end portion of the oblique slot formed vertically is. As a result, the curved plate prevents the The slide bolt can be pushed back as long as the Driving rod is adjusted. The lower end section of the Slant slot for the guide pin can be vertical to secure the position of the slide bolt.

1 shows a partial section through a door leaf 31 or by a sash frame, not shown otherwise Door or window. The cut is in the frame level or in parallel through the additional lock, in contrast a striking plate 12 is arranged in a frame 13 is installed. The reverse order is also possible, i.e. the installation of the additional lock in the frame or the installation of the striking plate in the casement.

According to Figure 1, a lock housing 17 is in a recess 32 of a wooden frame installed. This one has the frame 13 facing end face 33 with a fitting receiving groove 34, in which a drive rod impact is inserted. The person in question Driving rod 11 is in a conventional manner on one Cuff 35 attached, so that they are on the underside is vertically adjustable. The faceplate 35 is firmly connected to the lock housing 17 by rivets 36. she covers the fitting receiving groove and is otherwise not in shown by screwing with the door leaf 31st connected, for example, in the groove bottom of the fitting receptacle 34 are screwed in.

The drive rod 11 engages with a hook 11 'on one Curved plate 16, which is vertically movable in the lock housing 17 is led. Adjustments of the drive rod 11 therefore lead to that the cam plate 16 is adjusted up or down becomes. From the curved plate 16, the drive rod 11 resulting driving forces on the slide bolt 10 transfer.

The slide bolt 10 consists of two bolt parts 10 ', 10 '', limited to parallel axes 23 pivotable to store. The ends of the axes 23 engage Sidewalls 25 of a U-shaped slide bolt carrier 20, so that this, the axes 23 and the slide bolt parts 10 ', 10 '' form an installation unit. The locking parts 10 ', 10' 'are acted upon by a compression spring 37, each in opposite sense of rotation. The parts 10 ', 10' 'tend that is, to lie against each other. To a defined one To create a stop, there is a positioning stop 24, which connects the side walls 25 to one another and thus stabilized. The compression spring 27 presses each latch part 10 ', 10' 'against the stop 24, so that both together the Form slide latch 10.

The horizontal guidance of the slide bolt 10 is carried out by two mutually parallel horizontal slots 21 of the lock housing 17 guaranteed. A horizontal slot 21 in one shown wall of the lock housing 17 is dashed shown because it is located behind the curved plate 16. The other horizontal slot 21 is not in the shown, to be thought above the display level Wall of the castle housing 17th

In the horizontal slot 21 or in both slots 21 engages a guide pin 19 vertical to the display plane with which the slide bolt carrier 20 is acted upon. On further, not shown parallel guide pin can also engage in the horizontal slot 21 to tilt to better prevent the slide bolt. Instead, can also one of the axes 23 of the guidance of the slide bolt 10 Serve in the housing walls. Furthermore, the Guide pin 19 in an oblique slot 18 of the cam plate 16 a. When the drive rod 11 is adjusted Push bolt carrier 20 from the guide pin 19 according to the Slant of the slant slot 18 is adjusted. The latter forms part of the horizontal by an angle of less than 45 ° to achieve the largest possible bar feed.

Fig.1 shows the slide bolt 10 in its in the lock housing 17 enclosed position. If the drive rod 11 the cam plate 16 pulls down, the guide pin 19 shifted to the left in accordance with the oblique slot 18 and the two locking parts 10 ', 10' 'bridge the rebate space 18 and penetrate into the bolt pocket 39 of the striking plate 12 on.

The striking plate 12 has the shape of the slide bolt 10 adapted entry slot 40 in a mounting plate 41, which is fastened to the frame 13 with fastening screws 42 is. A wedge-shaped protrudes from the bottom 39 'of the bolt pocket Projection with two inclined surfaces 22 in the bolt pocket 39 in front of, and close to the slot 40. It is above also arranged so that the incoming bolt parts 10 ', 10' 'each on one of the two at an acute angle to each other arranged surfaces 22 accumulates. This is in Fig.2 shown. As a result, the locking parts 10 ', 10' ' raised in each case, which if the Push bolt 10 for a correspondingly limited pivoting movement about the axes 23 in accordance with that through the inclined surfaces 22 leads certain stroke.

Each latch part 10 ', 10' 'is provided with a hook 14. The hook 14 is arranged transversely, the hook 14 of the upper pivot bolt part 14 faces vertically upwards, while the hook 14 of the lower pivot bolt part 10 ″ vertically points down. As a result of the striking plate 12 formed spreading device 15 get the hook 14 behind one edge 41 'of the mounting plate 41. As a result is a pulling out of the slide bolt 10 in the horizontal Direction of Fig.1 by appropriate violent It is not possible to enlarge the rebate area. Also a relocation of the door leaf 31 down or up is prevented. For example, when the door leaf 31 moves below the upper latch part 10 'on the one assigned to it Rest inclined surface 22 and at the same time on an edge of the Cuff rail experience a support, so that another Swivel movement is excluded. It is also not possible forcibly push the slide bolt into the lock housing 17, since the guide pin 19 in the upper end portion 18 'of the oblique slot 18 is arranged and is supported there.

1, 2 show a comparatively large rebate area 38. If this is smaller, it must be ensured that the Push bolt 10 can be ruled out sufficiently far without to be acted upon prematurely by the spreading device 15. In this case, the inclined surfaces 22 of the striking plate 12 arranged at a larger angle to each other. In order to then the free path between the end of the slide bolt 10 and the inclined surfaces 22 is not too large, so that the slide bolt possibly not in the horizontal predefined for him Position can be from the cutting edge of the two inclined surfaces 22 a guide web up to slot 40 of the mounting plate 41 be guided so that the slide bolt parts 10 ', 10' ' the inclined surfaces on one side of this guide bar 22 can be fed according to the situation.

1, 2 is formed by the striking plate 12 Spreading device 15 shown. Show in comparison the 3.4 a spreading device 15 ', which is in the area the slide bolt 10 is located. Accordingly, the bolt pocket 13 of the striking plate 12 with a flat bottom 39 ' provided, but otherwise designed according to Fig.1,2.

In the embodiment of Fig. 3, 4 the of the drive rod 11 in the cam plate 16 transmitted driving force by means of an oblique slot 18 on the slide bolt 10 transferred. This is essentially sleeve-shaped and stores in its interior a slide 26 which is coaxial is arranged and is movable relative to the slide bolt 10.

The push bolt 10 is driven with a guide pin 19, which through the oblique slot 18 into the Horizontal slot 21 of the lock housing 17 engages. On further, not shown, with the guide pin 19th aligned guide pin of the slide bolt 10 engages in one Horizontal slot 21 above the display level thinking housing wall.

The oblique slot 18 in FIG. 3, 4 is the oblique slot 18 Similar to Fig.1,2, so also has a vertical End section 18 'for supporting the slide bolt 10 in the latter Extension position. So that the edges in this extension position 41 'of the mounting plate 41 can be engaged and thus a corresponding security effect is achieved The slide bolt 10 is provided with hooks 14 which can be moved across are. The hooks 14 are, for example, round cylindrical pins, the coaxially in a transverse bore of the slide bolt 10 are arranged. Their length corresponds to half the diameter of the slide bolt 10. You have near the central axis of the slide bolt 10 oblique slots arranged at approximately 45 ° 29, engage in the actuating pins 30, which with the Slider 26 are firmly connected. This to the display level vertical pins 30 are directly on the striking plate side End of the slider 26 arranged so that this in the Fig. 3 position shown distance from the striking plate side End 42 of the slide bolt 10 has. The slider 26 becomes relative moved to the slide bolt to the left, so press the actuating pins 30 of the slide 26, the hooks 14 to the outside or up and down. According to FIG. 4, however, this only happens when the slide latch 10 is completely in its excluded Position is reached. Only then will one be at that Slider 26 arranged cross pin 27 by means of an oblique slot 28 of the curve plate 16 in its vertical adjustment moved further while the guide pin 19 are standing remains. For this purpose, the slide bolt 10 has a groove for the cross pin 27, which is as long as the relative travel of the cross pin 27 corresponds.

There is a corresponding relative shift between the slider 26 and the slide bolt 10 in the sense that the hooks 14 are displaced upwards and behind the Edges 41 'arrive. The axial displacement of the actuating pins 30 corresponds exactly to the axial position difference between the cross pin 27 and the guide pin 19, as can easily be seen from FIG. It is therefore possible to keep the bolt pocket 39 correspondingly flat or their entire depth constructively for the dimensioning of the hooks 14 and their oblique slots 29 or actuation pins 30 to take advantage of.

Fig. 3,4 show that in addition to the guide pin 19 also the cross pin 27 in horizontal slots 21 of the lock housing 17 can intervene, so that there is an improved horizontal guidance of the slide bolt 10 results.

The additional lock could also be a screw-on box lock be the one to lock as an additional lock on each door or on each Element can be attached. The connecting rod can then, for example, in the manner of a basket string the wing be mounted.
