Box lock with locking bracket

The invention relates to a box lock with an abutment on the bolt Mounted locking bracket comprising two in the lock case parallel to each other and displaceable at a distance from each other stored, by means of a handle and / or cylinder lock or the like. Actuatable bolt, namely one between a locking position with engagement in a locking recess of the locking counter-bearing and an open position locking bolt movable out of engagement in the locking recess and one between a locking bracket driving position and a locking bar release position movable locking bar driving latch, wherein in the locking bar driving position of the Locking bracket driving bolt when the locking bolt is in the open position of the lock case relative to the bolt counter bearing in a direction perpendicular to the bolt axes from a mutual closed position in which the locking bolt with the locking recess is aligned and the locking bracket is in a closed position, in a mutual gap opening position is movable, in which stomata-

ment of the sliding along the locking bracket during the opening movement attacking locking bar driving bolt on a movement stop of the in a gap opening position the locking bracket located.

In a known box lock of this type (price list no. 41 from EWA), the two bolts are each individually operated by a separate handle (toggle). The one above the safety bracket driving bolt

, Q te locking bolt penetrated in the mutual locking position of lock case and counter bearing (closed door or window or the like.) A corresponding through opening of the hinged above the locking bolt on the counter bearing Locking bracket. In the mutual closed position

, p- The locking bar drive bolt engages the lock case and bolt counter bearing in its locking bracket driving position through a driving slot of the locking bracket into a Reception opening of the bolt counter bearing into it. This receiving opening is open in the direction away from the fastening surface of the bolt counter bearing, e.g. on the door leaf, so that the door can be opened by a gap until finally the one from the receiving opening of the bolt counter-bearing escaping locking bar driving bolt to the end of the driving slot of the corresponding swiveling The locking bracket strikes. A prerequisite for opening the door gap is, however, that the locking bolt has previously been removed from its Locked position has been moved to its open position. Operating two toggles carries the risk of incorrect operation in itself, which is reinforced by the fact that, as a rule, technically less experienced people also do so have to operate the box lock in moments of increased excitement. For example, there is the safety bracket driving bolt already inadvertently in its locking bar release position and actuates the operator when the bell rings the front door accidentally the toggle for the locking bolt, so that this from its locked position in its opening

-τι position, the front door can now be contrary to the intention can be opened unhindered by the operator. Another disadvantage of the known arrangement is through the separate operability of the two latches required a relatively high structural effort and the relatively high manufacturing costs has the consequence. It is also not possible to have both latches from the outside via a single one Cylinder lock to use.

IQ The object of the invention, on the other hand, is that To improve the box lock of the type mentioned so that it is easier to use with a simpler structure and offers greater security against break-ins.

This object is achieved in that the two brackets simultaneously by means of a common handle or Cylinder lock or the like. Can be displaced between three common positions, a first position in which the locking bolt is in its open position and the locking bar driving bolt occupies its locking bar release position, a second position in which the locking bolt a Intermediate position and the locking bar driving bolt assumes its locking bar driving position, and a third Position in which the locking bolt is in its locked position and the locking bracket driving bolt is also in a locked position engages in a bolt recess of the bolt counter-bearing, and that in the intermediate position of the locking bolt the locking bracket from the locking bolt can be moved freely between its closed position and its gap-open position is. In the third position of the two bolts, both of them engage in corresponding (laterally closed) bolt recesses of the bolt counter bearing, so that double burglary security is given. Should the door be in the stomata position are brought, so only the single handle is to be operated once, so that the bracket in the second Get in the position in which the locking bar driving

bolt take the locking bracket with you, unhindered by the locking bolt can. Since only a single handle is provided, a correspondingly simplified structure also results the possibility of actuation in addition to or instead of

the handle by a cylinder lock or the like. 5

In a further development of the invention it is proposed that in the mutual closed position of the lock case and The counter bearing of the locking bar driving bolt is closer to the mounting point of the locking bar on the locking bar counter bearing than

the locking bolt and is preferably immediately adjacent to the mounting point. This achieves that the Locking bolt in the stomata position approximated to The opening direction, e.g. of the door leaf, runs so that with a given opening gap width a relatively short, only slightly exceeding the length of the opening gap Locking bracket can be used. This creates the possibility that the bracket length of the locking bracket in the essential to the length of the bracket in the closed position

parallel dimension (height) of the lock case. 20th

This results in a compact box lock with an attractive appearance and eliminates the risk of getting stuck or even injuring yourself on the hanging safety bracket.

In order to ensure with an appealing bow shape that the

ser in its closed position does not penetrate into the feed path of the locking bolt, it is proposed that the locking bracket is formed approximately Z-shaped cranked twice.

A particularly simple, mechanically robust structure with low manufacturing costs is guaranteed if the two Latches are attached to a common locking plate within the lock case.

To the same box lock both with the right stop, such as

To be able to use even when the door is hinged to the left, it is suggested that the latch or the latch plate be used as an option Swap the bolts in the lock case in two by 180 ° around a plate center axis parallel to the bolt axes mutually rotated insert positions can be used in the lock case.

So that the latches in both positions of use as positively as possible in the corresponding guides of the Lock case as well as in the bolt recesses of the bolt counter bearing are held, it is proposed that the latches have the same cross-section, preferably circular cross-section, exhibit.

The invention also relates to a bolt abutment, which 15

are preferably, but not exclusively, used as part of the box lock described above can. Conventional bolt counter bearings for box locks with locking shackles consist of a single zinc die-cast

_nn piece. Its production costs are comparatively low, but there is a risk of destruction, in particular if the door is opened with the locking bracket attached and then acted on the door with great force in the opening direction, which usually leads to damage

_Or if not even destruction of the brittle zinc die-cast material

leads. To with only slightly increased manufacturing costs and yet attractive appearance of the bolt counter-bearing To achieve a substantial increase in security against burglary, it is proposed that the bolt abutment be a

OQ base plate and a counter bearing housing attached to the base plate has, and that the locking bracket at least partially on the with mechanically highly resilient material, preferably sheet steel formed base plate is supported. The division into two makes it possible to make the base plate out

"^ To produce mechanically highly resilient material without the appealing exterior is lost because the counter-bearing

housing can still be made as a cast part. Due to the at least partial retention of the locking bracket However, there is a significantly increased mechanical strength on the base plate, in particular when if the base plate is made of sheet steel, which, due to its toughness, can also be subjected to shock loads without further withstands.

It is proposed here that the base plate be provided with a bracket which has an outer side surface of the counter bearing housing is opposite at a distance, and that there is a hinge pin between the bracket and extends the counter bearing housing on which the locking bracket is mounted. Such a bracket can be through corresponding punching and embossing can be produced quickly and inexpensively. The locking bracket is on one side of the Locking bracket held on the bracket and on the other side of the bracket on the counter bearing housing. The one here The force exerted on the thrust bearing housing by the locking bracket is only half of the total force exerted by the locking bracket the force exerted on the counter bearing and thus usually below the lower limit of the damage of the counter bearing housing leading forces. The joint

^The bolt can also serve as a screw connection between the base plate and the counter bearing housing.

In a further development of the invention it is proposed that a second bracket in the area of the locking recess for the locking bolt is provided, and that a fastening bolt is located between the second bracket and the counter bearing housing extends. This second bracket in the area of the other locking recess increases the mechanical strength the arrangement, as it is when the bolt recess is loaded through the locking bolt in the event of a break-in attempt to directly divert the forces that occur here comes from the counter bearing housing to the second bracket. The fastening bolt can also be used as a stop for

serve the locking bracket in its closed position.

To the bolt counter bearing without replacing any components, both with a hinged on the right as well as

for a door hinged on the left or the like 5

to be able to, it is proposed that the two brackets are arranged symmetrically to the two bolt recesses. In adaptation to the desired type of installation must then only the upper end of the locking bracket is inserted between the upper bracket and the counter bearing housing and then insert the top bolt in each case.

The possibility of a quick and easy attachment of the counter bearing housing to the previously on the ground

fixed base plate is obtained according to the invention by at least 15th

a plug connection between the base plate and the counter bearing housing with a plug projection provided on one of the two parts and a plug-in recess provided on the other part, and by at least one screw connection and / or riveted connection or the like. Between the base plate and the counter-bearing housing, the respective plug-in projection in protrudes in a direction substantially parallel to the screw or rivet bolt axis.

The bolt abutment is generally located in Be-25

rich of a frame vertical edge, behind this

Frame area is a corresponding corner area of the wall opening for the door or window or the like. In order to secure anchoring of the base plate, in particular ■ in the masonry, it is proposed that the

Base plate with at least one through-hole for a fastening anchor that is inclined to the plane of the plate is provided. The inclined bore axis preferably lies in a plane perpendicular to the door frame plane and to the longitudinal axes of the bolt parallel plane. The dowel channel drilled into the masonry as an extension of the through-hole

runs more or less diagonally into the masonry in relation to the nearest masonry edge, i.e. in more of the inner peripheral surface of the masonry opening and more distant masonry areas with increased pull-out strength.

To point loads between the head of the through hole To avoid used fastening anchor and the base plate, it is proposed that the Through-hole from a contact shoulder preferably formed by corresponding stamping of the base plate is encircled for the fastening anchor head, which lies in a plane which is essentially perpendicular to the axis of the bore. Such point loads would lead to a reduction in mechanical strength.

For doors that rest on the frame with a sash overlap, the sash overlap thickness is taken into account a base part · inserted between the frame and the actual bolt counter bearing. With the usual steel frames the available fastening surface of the frame is very narrow, so that the base part protrudes on the outside. In order to still be able to attach the base part to the wall without the risk of tilting, it is proposed that the base part which is only partially in contact with the frame with its underside in the area of the underside which is not in contact is provided with at least one height-adjustable foot to rest against the wall carrying the frame. The height of the foot is adjusted according to the thickness of the frame.

The base part therefore lies flat against the frame as well as against the wall via the at least one foot, see above that the bolt counter bearing also differed on narrow frames Licher frame material thickness can be attached easily.

In a preferred embodiment of the invention is

provided that the foot of one can be screwed into the base part Screw sleeve is formed, in the internal thread of which a fastening screw for attaching the counter-bearing housing or the base plate of the bolt counter bearing can be screwed into the base part. This ensures low Manufacturing costs, since no separate thread for the fastening screw is cut into the base part got to. There is also a comparatively higher pull-out strength of the fastening screw in the case of a mechanical one , Q less resilient material made base part because the thread to be cut into the base part for the screw sleeve has a larger diameter than. the fastening screw thread .

, ρ- A visually attractive covering of the space between the wall and the protruding base part are obtained by a non-adjacent to the underside of the base part Area arranged, formed in one piece with the base part or attached to the base part as a separate part.

2Q applied filler piece or lip profile, preferably from elastic material. In a first embodiment, the filler piece or lip profile is glued to the base part, which excludes the formation of local gaps between the filler piece or the lip profile and the base part.

However, it can also be provided that the filler or

Lip profile engages around the at least one adjustable foot under elastic pretension. You press accordingly the filler piece or lip profile on the adjustable feet, 3Q what without further measures for the desired connection of the two parts.

The invention is illustrated below using a preferred exemplary embodiment explained with reference to the drawing.

Now to the structure of the box lock 10 in detail.

The locking element 22 consists of a flat locking plate 22a, which is connected to the locking plate by rivet bolts 22b rigidly connected two bolts 24 and 26, one hinged to the bolt plate (pivot bolt c) Tumbler 22d made of identically shaped, arranged on both sides of the locking plate 2 2a, at one end over the pivot pin 22c and connected to each other at its other end via a connecting pin 22e Tumbler plates 22d 'and 22d *' (see also Fig. 3)

and one in a spring recess 22f of the locking plate 22a inserted, engaging the driver 22d and biasing this in the clockwise direction of FIG. 2 22g (see Figure 2). The two driver plates 22d 'are perpendicular to the horizontal direction Latch plate plane provided with one another aligned indentations, which in Fig »2 from the pivot pin 22c next indentation are denoted in sequence with 44a, 44b and 44c. At the free The end of the driver plates 22 # ', 22 #' 'is located a further indentation 44d which is only half formed. All indentations have the same distance, which the distance between two driver pins 46a and 46b corresponds. The two pins are vertical

Xf
from a plate 48 which is connected in a rotationally fixed manner to the toggle -36- and is arranged within the lock case 12. As FIGS. 1 and 3 show, the driver pins 46a and 46b each engage in two adjacent indentations 44 in accordance with the respective position (first to third position of the locking element 22). In the third position shown in FIG. 3, the pin 46a engages in the indentation 44a and the pin 46b in the indentation 44b. In the second position (intermediate position) after turning the toggle 2-6 counterclockwise by 180 ° in FIG. 1, the pin 46b still engages in the indentation 44b, whereas the pin 46a now engages in the indentation 4 4c . Accordingly, in the third position, the pin 46a engages in the indentation 44c, whereas the pin 46b engages in the indentation 44d. The prestressing spring 223r biases the driver 2 2d in the direction of the driver pins 4 6a and . 46b the Schloßkastcn has a two-part Schloß- ,, box housing, consisting of a base plate 50 and a /J..// placed on the base plate box / p /.;'/ shaped cover 52. the base plate -. 52- is screwed tightly to the door leaf 14 by means of a total of four fastening screws 54.

The bolt abutment 16 comprises a base part 60 placed directly on the door frame or the wall 20 as well a lock case 66 screwed onto the base part 60 and made up of a base plate 64 and a counter-bearing housing 62.The base part 60 is designed as a box that is open towards the frame 18. As in particular Fig. 4 shows, the frame cheek 18a, which is parallel to the door frame plane and rests on the wall 20, is thus in a horizontal position Formed narrow in the direction that the base part 60 rests only about halfway against the cheek 18a. In order to prevent the base part 60 from tilting, it is supported by a total of two screw-in sleeves 68 on the side of the wall 20 facing the room to be locked. To adapt to different The screw-in sleeves 68 can extend cheek thicknesses a to a greater or lesser extent into corresponding ones on the base part 60 formed screw-in thread 60a are screwed in more or less far. To facilitate the The screw-in sleeves 6 8 can be screwed in at their end remote from the wall with a screwdriver slot 68a be provided.

To conceal the gap between the wall 20 and the base part 60, a lip profile can be placed in this gap 70 be used, the sealing lip 70a of which is similar to an apron

-16-

\ rests against the wall 20, extending in a U-shape along the outline of the base part (see FIGS. 1 and 4). To simplify the illustration, the lip profile 70 has been omitted in FIG. To attach the lip profile 70 to the base part 60, the lip profile 70 is provided with passage openings 7ob, the diameter of which is slightly smaller than the outer diameter of the screw sleeves 68. Accordingly, the lip profile made of elastic material according to FIG. 4 can be pushed onto the two screw sleeves 68.

The two screw-in sleeves 68 are each provided with a Internal thread 68b provided, in which fastening screws 7 2 for fastening the base plate 64 to the base part 60 according to FIGS. 1 and 4 can be screwed in. Corresponding, on the inside facing away from the wall 74 of Baseplate 64 recessed through openings 64a can be seen in FIG. 7. In addition to the two with the screw sleeves 68 aligned openings 64a ι ™ area of the rear remote from the lock case 12 The vertical edge of the base plate 6 4 are three Weitepe fastening openings on this in the area of the front vertical edge 64 ^ provided in which gc incl-rt

Qi, v »; '.. Vl j

Again, countersunk head fastening screws 73 can be used and in corresponding thread 60b of the base part 60 can be screwed in.

The base part 60 can be fastened to the frame 18 with screws (not shown). About burglary security to increase, however, the base plate 64 is anchored directly in the masonry of the wall 20, namely by means of two in FIGS. 1 and 3 recognizable screw-in fastening anchors 76, which are screwed into masonry dowels 7 8 within the wall 20. The fastening anchor axis 76a lies in a plane perpendicular to the door frame plane and parallel to the bolt axes 80 Level (in the example shown: horizontal plane); the axis 76a is opposite the perpendicular to the frame plane

right-hand reference direction 82 inclined at an angle oc, in the direction from the fastening anchor head to the dowel 78 away from the door frame interior 8fl. In the preferred embodiment shown, the angle oe is /, _%

Execution at around 30. As Fig. 5 shows, / .-,

the base plate 64 with corresponding holes 86 Durchtritts- /,../ for the two fastening anchor 76 // ■■■, _y f provided, said openings characterized 64a.derart _'s / are such that the axis of the cylindrical Durchtritts-

IQ bore 84 runs inclined according to the angle and furthermore on the inside of the base plate 64 facing away from the wall 20 an annular contact shoulder 84a for the underside of the fastening anchor head is formed. The bore 84 can optionally

Ig as a drilling jig for setting the two dowels 78 can be used. The contact shoulder 84a prevents mechanical stress peaks. For the passage of the respective fastening anchor 76 through the base part 60, this is with a corresponding passage opening 8 6, which merges into the aforementioned opening 84. The fastening anchors 76 occur the open underside of the base part 46 from.

The counter bearing housing 62 is similar to the base part 60 approximately designed as a box open on one side towards the wall 20. In the lock case 12 facing front vertical side wall 62a are intended to receive the two latches 24 and 26 Lock recesses 28 and 30 in the form of cylindrical Through holes formed. Fig. 4 shows a such locking recess in section. In the front wall In addition, two screw-in bores 62c are cut into 62a, into each of which a bolt 36 can be screwed is. Fig. 6 shows the lower of the two identically shaped bolts 36, which is from the countersunk head 90a has three sections starting out, a first cylinder section 90jf, a second, reduced-diameter Cylinder portion 90c and a third

-48-

Thread end section 9Od. The latter section is screwed into the thread 62c. The countersunk head 90a lies with the back of its head on a shoulder 92a at right angles on the outside facing the lock case 12 from the plane of the base plate 64 bent bracket 92 of the base plate 64. The between the cylinder sections 90c and 90b The radial ring shoulder formed lies on the outside of the wall facing the lock case 12 62a of the counter bearing housing 62. One in the direction Threaded bore 62d running perpendicular to the door frame plane and opening into the internal thread 62c takes on a locking grub screw 94, which after inserting the anchor 90 until it rests on the reduced diameter cylindrical portion 90c is screwed, which prevents the Armature 90 by inserting a screwdriver into its countersunk head 90a and turning it accordingly can be unscrewed, which increases the security against break-ins, because when the door leaf is in the gap opening position (see also FIG. 9) the two bolts 36 are accessible from the outside of the door.

When the two bolts 36 are screwed in, a plug connection between the counter bearing housing 62 and Base plate 64 made. This connector comprises one of one in a direction away from the lock housing 12 and plug-in projection 9 6a projecting parallel to the bolt axes on a plane of the base plate bent out at right angles and thus to the bracket 92 parallel tab 9 6 in the area of the mid-length of the base plate which is elongated in the vertical direction 64. When the bolts 36 are screwed in, this projection 9 6a penetrates into a complementary recess 62e on the inside of the vertical side wall 62f facing away from the lock case. This type of attachment it in turn makes it possible that the base plate 6 4 on the base part 60 as well as on the first

-vsr-

Anchor 76 attached directly to the wall 20 and then the counter bearing housing 62 is attached to the base plate 64.

As FIGS. 6 and 8 show, the lower bolt 36 serves as a stop for the freely hanging locking bracket 3 (Closed position). Here, the bracket lies with its longitudinal narrow side 34a facing the door leaf 14 on section 90b of bolt 36. It can be seen that in this stop position the lower bolt 26 is insignificant radial distance from the bracket 34 maintains, which ensures, the bracket 34 in no way protrudes into the feed path of the bolt 26.

The upper bolt 36 serves with its section 90b as a pivot bearing for the bracket 34; enforced for this purpose

the section 9Od a corresponding cylindrical

As FIG. 8 shows, the locking bracket 34 is cranked approximately two times in a Z-shape, starting from its pivot point at its upper end, in the direction away from the door leaf 14, so that when the locking bracket 34 is in the closed position according to FIG parallel end sections 3 4c (upper end section) and 34d on both sides of the double crank in the vertical direction and the lower end section 34d laterally past the bolt 26. From this position, the locking bracket 34 can accordingly be _{pivoted unhindered in a} clockwise direction (direction arrow B in FIG. 8). On its longitudinal narrow side 34d opposite the mentioned longitudinal narrow side 34a, the locking bracket 34 is provided with an edge shoulder 34e protruding on both sides of the plate-shaped bracket 34. The edge shoulder is also drawn over the lower short narrow side 34f of the bracket 34 in FIG. 8 (see also FIG. 6). This shoulder serves on the one hand to mechanically reinforce the bracket

3 4 and to change the appearance of the lock 10.

The longitudinal slot 32 mentioned at the beginning is cranked twice in accordance with the shape of the bow. The clear slot width j £ corresponds essentially to the diameter b of the diameter-reduced section 42 of the upper bolt 24. The other diameter c of the bolt 24, which is equal to the diameter of the bolt 26, however, exceeds the dimension b, so that the section 42 is reliable is guided within the longitudinal slot 32. The end of the bolt 24 which adjoins the section 42 and is further away from the bolt plate 22a also has the diameter c.

At the end of the longitudinal slot that is closest to the bracket pivot bearing (upper bolt 3 6), the slot becomes one enlarged diameter circular end portion 32a widened, the diameter d of which is the bolt diameter c essentially corresponds to. With the locking bracket 34 hanging vertically downwards (closed position 8) the end portion 32a is aligned with the axis of the upper bolt 24, so that this through the end section 32a can be advanced through into the locking counter bearing 16.

The bracket length e is slightly greater than the vertical length f of the bolt abutment 16, which the vertical length of the lock case 12 corresponds.

The function of the box lock 10 is evident from the above. As already stated, the two bolts 24 _f and 26 can be moved jointly between three positions by corresponding rotation of the toggle ^ kr , a first position in which the bolts are retracted into the lock case 12 and the door leaf is accordingly un-
