Description

Bar lock for mounting in a breakthrough in a thin wall (indirect clip fastening)

The invention relates to a bar lock for mounting in a breakthrough in a thin wall, comprising a head part, such as flange, key plate, handle rosette or Betätigungshebelmulde, with a the outer breakthrough edge of the thin wall covering the edge region, emanating from the head part, after mounting the breakthrough protruding body part are formed or supported by the holding surfaces, which rest after mounting on the inner breakthrough edge of the thin wall.

From EP 0 261 266 A1 a bar lock for mounting in a breakthrough in a thin wall is known, see for. Example, Fig. 23, comprising a head part in the form of a Betätigungshebelmulde, emanating from the head part, after mounting the breakthrough protruding body part formed by a fastened with screws on the head part lock case are formed or supported by the holding surfaces, which after mounting on the create inner breakthrough edge of the thin wall, here formed by an edge of the lock box. The disadvantage here is the arrangement of the screws, which make it cumbersome to assemble the rod lock, especially when installed by robots.

The object of the invention is a development of the known rod lock to the effect that without screws the assembly is made possible.

The object is achieved in that the fuselage part (or the head part) has a retaining element receding against spring force, which engages a support element emanating from the head part (or fuselage part) during assembly.

This eliminates the need to make the assembly by means of screws.

Rather, the connection by means of clip or locking devices is possible. Thus, according to one embodiment of the invention, the receding against spring force retaining elements with the head part integrally molded, made of plastic struts that have near or at their ends a projection or recess, which engages in a recess formed by the hull part or projection. A detent mounting is much easier than a screw fastening.

Alternatively, an embodiment in which the retaining elements receding against spring force with the body part integrally molded, made of plastic struts representing near or at its end a projection or recess which engages in a recess formed by the head part or projection.

Another alternative is that in which the retreating against spring force retaining elements in the body part parallel to the thin wall slidably mounted against spring force slide whose free end has an inclined surface for backlash-free support of the body part on a Rücksprung- or protruding surface of a outgoing from the headboard , the breakthrough approach is formed.

In other embodiments, therefore, the connection between the body part and the head part does not take place, as in the prior art, by means of cap screws, but by means of clip elements.

In particular, the play-free support of the body part on a recess or projection has the advantage that the storage of the rod lock within the breakthrough in the thin wall is made possible without play.

To facilitate the insertion of the two parts together, it is advantageous if the approach has at its free end an inlet inclined surface for the carriage.

The conversion from right to left is facilitated if the fuselage in is formed substantially symmetrical about a plane parallel to the wall.

In this case, it is favorable if the body part is divided at the plane of symmetry and the two parts form receiving spaces for one pinion and for two centrally perforated opposing flat band bars for meshing engagement of the pinion.

Alternatively, however, the body part may also comprise a pinion which is divided at the plane of symmetry, the body part forming receiving spaces for the two parts of the pinion and for two centrally and / or laterally perforated, opposing flat-band bars symmetrical about their center line for meshing engagement of the pinion , In both cases, symmetry is also present here.

The latter two embodiments differ in that in one case the lock case is divided, in the other case, the pinion.

When split pinion, it is advantageous if the body part has on the plane of symmetry a wall separating the two receiving spaces for the pinion parts, which has an opening for a drive shaft for the pinion parts. As a result, the overall pinion formed by the two pinion parts is held in place.

A particularly favorable construction results when the body part to the symmetry plane form symmetrical receiving spaces for the carriage and a spiral compression spring provided for each carriage, which is supported on the one hand at an inner end of the receiving space for the spring, on the other hand on a bearing surface formed by the carriage for the Feather.

The contact surface of the carriage for the spring could be formed by the one edge of an opening in the carriage, which partially surrounds the spring.

For pre-assembly of the lock case, it is advantageous if the two body parts have aligned centering projections / centering recesses. Operationally, it is advantageous if the holding elements in their holding position by pin or the like. Lockable. As a result, an unwanted displacement or separation of the two halves of the lock case is avoided.

The direction and movement of the holding elements should be parallel to the direction of the bar movement in order to prevent tilting.

It is particularly favorable if the opening in the thin wall is an elongate rectangle whose longitudinal axis lies in the direction of the bars.

The rod lock may have a pivot lever drive, but alternatively also have a fast handle drive or a socket driver.

A fundamental advantage of the arrangement according to the invention is that the bar lock with pre-assembled rods in the head part, such as in the trough, can be clipped. The holding elements, which are clips, so do not rely on the edge of the sheet metal cutout, but drive into breakthroughs in a created structure of the key plate. The key plate is pulled even closer. The shoulder of the key plate with, for example, an O-ring seal abuts against the door leaf and the bar lock rests in a manner known per se on the inner edge of the installation opening and clamps the door panel as in the prior art. A cap or a cap member as in the prior art is no longer necessary here, because according to the invention a unit has been created which consists of the lock case (one or two parts), the rods, the pinion (one or two pinions), which unit itself connect by Klipsvorgang with the key plate (headboard).

As in the prior art, all conceivable external operations can be used here, such as a key plate, long or short, toggle and latch handles, as well as pivot levers.

Do you make the holding elements that serve for clipping, double T-shaped in cross section, The two halves of the two-piece lock case can be held together by them, so that a riveting or screwing could be omitted. On the outer lock case half meet no forces. Even with the use of a tongue for three-point locking is derived over the shoulder of the actuator, which is bolted to the tongue, only force on the inner lock case half.

The invention will be explained in more detail with reference to exemplary embodiments, which are illustrated in the drawings.

Lock case, and

Figs. 32A to 32F show still another embodiment.

Fig. 1A is a side view of bar lock 10 for mounting in a breakthrough 12 in a thin wall 14, such as a sheet metal cabinet door panel comprising a head portion 16, the head portion being a flange, or, as in Fig. 1A, a trough 16 with an actuating lever 18, or a short key plate 216, or a long key plate 116 (see Fig. 1C), with a the outer breakthrough edge 20 of the thin wall 14 covering edge region 22, further comprising one of the head part 16, 116, 216, 316 , 416 outgoing, after mounting the breakthrough 12 penetrating body portion 24, such as lock case, supported or formed by the support surfaces 26, which create after mounting on the inner breakthrough edge 28 of the wall 14 nen ner so ß d the externa ßeren and at least partially enclosed in inner breakthrough edge regions 22, 28, for example along the half longitudinal extent of the two longer marginal edges, as shown in FIG. 1B, and clamped in place.

Instead, as in the prior art headboard or depression 16 to connect to the body part or lock case 24 by means of screws here has the body part or lock case 24 a receded against spring force retaining member 30 which engages a outgoing from the head part 16 support member 34 engages , In the embodiment shown in FIGS. 1A, 1B and 1C, the retaining elements 30 receding against spring force in the body part or lock case 24 are mounted slidably parallel to the thin wall 14 against spring force 32 and have a free end with an inclined surface 38 play-free support of the body part 24 on a recess or projection surface 40, which recess surface 40 or projection surface 140 (FIG. 10) emanating from a head part 16, 316, the breakthrough 12 protruding approach 42, 142, 442 is formed.

The advantage of this inclined surface is that the construction can adapt to different thicknesses of the door leaf 14, as well as to manufacturing tolerances. The lock box 24 will thus play the door leaf 14 between it and the trough 16 pinch and thus hold itself backlash.

In the embodiments shown in FIGS. 1A, 1 B, 1 C, the symmetrical holding elements 30 lie in the longitudinal direction of the closure and thus diametrically opposite one another, because in this way a particularly durable and tilt-free holder is made possible.

The approach 42, 142 has at its free end an inlet slope 44, which inlet slope 44 causes when inserting the lock case or body part 24, 124 between the two lugs 42, 142, the holding elements 30, 130 against the force of the spring 32 during insertion pushed back along the slope, which facilitates the assembly.

As is apparent from all embodiments, the body part is formed substantially symmetrically about a wall plane 46. A further symmetry results around the median plane 48, so that the component is doubly symmetrical, which facilitates the installation and also allows a change of the right-left function. In the embodiment shown in FIGS. 1A, 1B and 1C, furthermore, the body part 24 is divided at the plane of symmetry parallel to the wall and the two parts form receiving spaces for a pinion 50 and for two centrally perforated opposing flat band bars 52, 152 for meshing engagement of the pinion 50. The lock case 24 can be preassembled in that in one half of the rod 52 or the rods 52, 152 and the pinion 50 are inserted, whereupon then the second lock case half is placed and connected to the first lock case half, for example by riveting , or by Verklipsung or by cross-sectionally double-T-shaped holding elements 36, see Fig. 7B. The pre-assembled lock case can then be clipped onto the support members 42, 142 by this through the wall opening 12 are inserted through and the bar lock is mounted.

Instead of building the lock case from two halves, it is also possible to choose an embodiment in which the body portion 124 includes a pinion 150 which is divided at the plane of symmetry 25, wherein the body portion receiving spaces for the two parts 27 of the pinion 150 and for one or two centrally and / or laterally perforated counter-rotating flat-band bars 252 symmetric about their center line for meshing the pinion 150, see Fig. 12, where the two-part pinion assembly can be seen at 150 in Fig. 12 and Figs. 11A, 11B , as well as the associated rod in Fig. 14 is shown. In the one-piece pinion 50 according to FIGS. 9A, 9B, there are side walls 54 of the two lock case halves 56, see FIGS. 8A and 8B, which take over the axial guidance of the pinion 50. In the embodiment according to FIG. 12, on the other hand, it is a wall 60 which divides the two receiving spaces 58, 158 for the two pinion parts 27 of the pinion 150 and which has an opening for a drive shaft 162.

The body part or lock case 24, 124 further has to the symmetry plane 25 symmetrical receiving spaces 62 for the carriage 36, 136 and provided for each carriage coil spring 132. The coil pressure spring 32, 132 is supported on the one hand at an inner end 68 of the receiving space 64 for the spring on the other hand on a bearing surface 66 formed by the carriage, see FIGS. 7A and 7B. This contact surface 66 of the carriage 36 for the spring 32 is formed by the one edge of an opening 70 in the carriage, which surrounds the spring 32 partially. The holding elements according to FIGS. 7A and 7B, as shown in FIG. 7B, have a double T-shape in cross-section, which results in the lock case halves being prevented from falling apart when the holding elements are inserted into the two lock case halves, provided that the space is included 62 for the carriage has a corresponding recess surface 72, as can be seen Fig. 8C, where the head of the double-T-shape of the support member 36 can create.

To align the two lock case halves 56 to each other and a move To avoid in the preassembled state, the two body parts have aligned centering projections 74, here in the form of a pin, or centering recesses 76, here in the form of a bore. FIGS. 7A and 7B also show blind bores 78, into which, if necessary, a tool can be inserted in order to push the holding elements back into their release position. Alternatively, however, this blind bore 78 also serve to lock the holding element by means of a pin, so that it can not retreat by itself after mounting the closure.

The key plate may have a groove 80 for a sealing ring in a known manner.

The retaining surfaces 26 form according to FIG. 13 grip strips 82, which not only form the retaining surfaces 26, but also the lateral guidance of the lock case or body portion 24 with respect to the head portion or the trough 16 are used. This embodiment can be seen in Fig. 4, Fig. 5 shows that it is possible without this bar to obtain a stable leadership, the lock is then lower.

How here the operation is held in the headboard is of minor importance. For example, a shoulder 84 in the head portion 216 hold the operation with a square 86, as well as at the other end of the shaft a Vorreiberzunge 88 can be supplemented.

6A, 6B and 6C show in various views of a headboard or key plate, with the aforementioned inlet surface 44, also constructed with a hooking and fixing contour 92 for a preassembled bar lock, for example from the half of FIGS. 8A and 8B, wherein these halves has notches 90 for hooking with the shield or Ausschwenkhebelgriffelement.

Fig. 13 shows an end view of a one-piece lock case 124 in which the two-piece pinion 150 is preassembled. The pinion halves 27 of the pinion 150 are over a crown contour 94 drehstarr verkuppelbar with each other and has a square bore 95. With such a double pinion any drives can be connected, for example, shown in Fig. 12 preassembled actuating mandrel 96 which is held with its cap screw 98 on the pinion.

The structure of FIG. 12 can be pre-assembled with rods, for which the rods are positioned with their open teeth 100 in the one-piece lock case 124, whereupon then the two pinion 150 can be pushed in its axial direction on both sides of the rod teeth, then by screw and spike to be committed.

Now, the closed (perforated) portion 101 of the teeth of the rod 152 can be inserted into the lock case.

The two open serrations 100 are thus necessary only for assembly.

FIGS. 15A, 15B show an embodiment in which the holding element 436 is not symmetrical, as in the embodiments according to FIGS. 1 to 13, instead the holding element 436 is here provided with an inlet bevel 441, which makes the holding element asymmetrical power. This has the advantage that the inlet slope does not have to be attached to the projection 442 of the head part 460, which shortens the overall height. However, the lock box or body 424 may be turned so as to selectively enable right or left operation. For this purpose, the holding member 436 is alternately inserted, so that the inclined surface 438 always comes to lie in the direction of the edge 440 of the projection 442.

Thus, for example, by a bore or a recess 78 in the holding element 436, the hull element 424 disassemble from the head member 416 to subsequently extract the holding members 436 from the body part and turn, so that even a subsequent change from right to left is possible.

The stability of the arrangement can be increased when the head part 416 with its Latches 442 and fuselage 424 nested in the mating. This could be achieved, for example, by means of a strip 73 formed by the fuselage part, behind which legs or lugs 434 bear with their strip 75 in support, see FIGS. 15A and 17 or FIG. 18.

This interleaving or mutual support, for example, prevents the lug 434 from bending outwardly under the pressure of the inclined surface 438 of the retaining element 440 when the clips engage.

FIGS. 20A to 20C show, in three different views, yet another embodiment of a bar lock 510, wherein the nesting is even more pronounced than in the case of the embodiment described above according to FIGS. 15 to 19. Thus, the head part 516 points downwards reaching approach 542 with a wall 577, which forms at its free end a support strip 575 to abut against a recess 573, which is formed by a slot 579 of the body portion 524.

Slot 579 and return 573 thus take up edge 577 with hooks 575 and support each other.

Thereby, the receiving surface 540 for the inclined surface 538 of the holding member 536 shown in FIGS. 21A and 21B can be securely picked up without yielding.

The body part 524 here is made up of two halves, one half of which can be seen in three views in FIGS. 23A, 23B and 23C.

In Fig. 23C, for example, in the lock case half 556, the receiving spaces 557, 559 can be seen for the locking bars.

Here too, a cross-sectionally double-T-shaped retaining element, see Fig. 21 B, serves to hold the two halves of the lock together. Again, the support member 536 is provided with an inclined surface 540, as an assembly aid for better running when mounting the lock case in the head part, which, however, the support member 536 also makes unbalanced, so that a measure is provided here to the lock case for implementing the holding elements be able to disassemble again, including a recess 561, in which a tool or the like., Such as screwdriver, could be inserted through a slot 563 in the lock case 524 to release the retaining element and remove the lock case from the headboard.

Figs. 24A, 24B, 24C, 24D, 24E, 24F, 24G, 24H and 24I show, for further illustration, various partially cut and partially perspective views of the embodiment of Figs. 20A to 23B, while Fig. 25 is an exploded perspective view of this embodiment. Corresponding parts therefore bear the same reference numbers.

In Figs. 25A to 25F, there is shown an embodiment which is changed from the embodiment of Figs. 24A to 24F in that the operating mandrel is different. In addition, a corresponding opening 12 for the lock case 656 is shown in FIG. 25G.

The embodiment shown in Figs. 26A to 29B is suitable for the operation of a spine actuator, as indicated in Fig. 26A, and pivot lever operation, see Fig. 29A. The specially designed attachment hook 17 holds the trough 716, similar to FIG. 1A, the trough 16 in the sheet metal cutout 13 in the lower region fixed. The attachable cap 715 shown in Figs. 29A and 29B has only the gasket 781 to press against the door leaf 14, which is shown in Fig. 29A in cross-section and conforms as a molding of the cap shape. At 783 in Fig. 29B possible clip surfaces are indicated, which cooperate with corresponding corrugations of the clip surfaces 785 of the trough.

The pinion 750 of FIG. 29A drives the shutter bars 52, 152 and is itself driven by a lever 718 via a square mandrel. A pre-assembly of the Handle 718 in the trough 716 may be made by a shaft lock 719.

Referring to Fig. 26A, a socket operation 796, e.g. B. as a square, or as a handle operation, always shown in dashed lines, provided.

The two halves of the lock case 724, one shown in FIGS. 28A and 28B, are clipable by spring inserts 723 received in corresponding pockets 729 with clips, the springs of the tabs 723 engaging behind handle edges 731 and the clipped two To unite halves to a lock box 724. The resulting lock case 724 has pockets 733 for carriage 736 and a pocket 735 for the associated spring 732. Similar to other embodiments, go from the head part or the trough 716 support members 734, with inlet slope 744, which when placing the Schloßkastens 724 on the support members 734 of the trough 716 slide the carriage 736 to the outside. Characterized the spring 732 is tensioned, which then penetrates in the position of the lock box 724 on the support member 734 in the opening opening with recess area 740 and locked there.

For the mounting of the carriage, a finger grip 737 is provided with which the carriage 736 can be pulled out and thereby passes into the release position.

Head portion 716 may include a centering lug 739 to center the head portion 716 in the wall cutout 12. By turning the lock case 724, see Fig. 26B, the embodiment can be changed from left to right.

The lock case 724 shown in Fig. 29A has a recess 741 into which a projection 739 projecting over the plate 14 can penetrate so as to center the lock case.

In principle, however, an embodiment is possible in which the lock case is not in two parts, as described here, but is designed as a part with possibly split pinion. Also in the embodiment shown in Figs. 30A to 30E, the lock case 824 can be disconnected from the clipped key blade or body 816 by operation of keys. The pushbuttons 837 shown in FIGS. 30A to 30D are simply inserted prior to assembly of the lock case 824 and are limited in their internal movement, but upon actuation push the clip members 836, which do not perform linear motion but pivotal movement, back to the release position.

The four rivets 821 shown in Fig. 30E may also be replaced by rectangular clips to hold the lock box halves together when made of a suitable compliant material such as polyamide PA.

The holding element 836 with the spring 832 is arranged pivotably about an axis 11 arranged parallel to the plane parallel to this plane and has at its end a rising curve 13, with which the holding element 836 lays in the end position behind a rear grip surface 45, as already shown in FIG 30C recognizable. In this position, the component 824 can no longer move away from the component 816. At the same time the door panel 14 is clamped between them and then simultaneously again under centering, as already described, the fitting held in the door leaf.

Only upon actuation of the two-sided pushbuttons 837, the support elements 836 reach their release position, so that the rod lock 810 can then be dismantled.

Incidentally, FIG. 30D also shows, in addition to the folded door leaf 14, a door frame 114, which both form a fold region in which the compact lock 824 can be accommodated. The key plate 816 may be provided for socket wrenches, handles in L or D shape as well as for lever locks.

The support shaft 11 carries in Fig. 31 in an alternative embodiment, a leaf spring 936, which is bent accordingly, so that they are on the one hand on the abutment 949th supported, on the other hand, its rising surface 931 can be supported on the Hintergrifffcheche the lock case 924 and so holds the components of the closure together.

Figs. 32A to 32F show a particularly simple embodiment in which, in a kinematic reversal, the carriages 1036 are formed or carried by the head part 1016, see in particular Figs. 32B and 32F.

The carriages 1036 - two opposing metal plates enclosing a coil spring 1032 - each engage a lug or support member 1026 formed by the lock case 1024 upon assembly, which lug 1026 in turn engages the inner breakthrough edge 1028 of the thin wall 1016, so far as well here an "indirect Klipsbefestigung" before.

In the illustrated embodiment, a rotary latch 1000 is provided instead of the rods, but this (or one with the illustrated drive - square 1096 - torsionally rigid connected (double) lever) additionally have hinged to him rods.
