Best ways of carrying out the invention

Fig. 1 shows a handle 10 with a closure insert 12 for mounting in a preferably thin wall 14, such as sheet metal door leaf 14, in a door frame 16, see Fig. 2 , may be hinged, or as a sheet-metal drawer front, which is insertable in a cabinet, or as a sheet-metal box lid, which closes a metal box, wherein the handle 10 has a longitudinal extent, at the ends 18, 20 each at least one fastening means, such as screw, nut , Hook or clip fastening 22, 24 is arranged, see also Fig. 5 ,

Fig. 5 shows how a closure insert can be constructed. Thus, the closure insert comprises a housing 26, which includes a collar 28 near its front end 32, wherein a receiving space 30 for the front end of the housing 26 is provided with the collar 28 in the handle end near the one fastening means starting from the support surface with the thin wall, which receiving space under change (reduction, circular shape) passes through the handle to the front of the handle.

Appropriately, the receiving space 30 has a similar contour as the collar 28, for example, a square contour. This results in a rotation lock.

It is advantageous if the front end 32 of the housing 26 on this side of the collar 28 has a round contour, which is expediently coaxial to the square collar 28. In this way, the housing 26 may be arranged in four different directions of rotation. This is expedient with shutter closures as provided here.

The rounding of the housing 26 may include beyond the collar 28 tendon-like constrictions 36 which are provided at four edges to here also a rotation lock within the correspondingly shaped aperture 38, 238 (FIG. Fig. 6 ) in the thin wall 14, 214.

In the housing 26 may according to Fig. 5 be included commercially lock cylinder 40, the lock core 42 is provided with a square 44, on which square 44 in four different positions offset by 90 °, a correspondingly shaped Vorreiber 46 attached and fixed by means of screw 48.

The lock core 42 may be rotated when a corresponding key is inserted and the core suitably releases the corresponding tumblers. After assembly results in a closure insert 12, shown in cross section according to Fig. 5 , As Fig. 5 can be seen, the receiving space 30 between two spaced-apart fastening means 22, 24 is arranged. Accordingly, the bore 61, in Fig. 6 , disposed between the bores 54, 56. The assembly is done in such a way that first the introducer inserted through the opening 38, 238 and then the housing 26 is pushed through, which comes to lie on the surface of the door leaf on the thin wall 14, 214 by means of the collar 28. Then, the handle 10, 210 with the two arranged at both ends fasteners, here in the form of Klipsanordnungen 22, 24, inserted through apertures 54, 56 and clipped, wherein the housing penetrates with the collar in the corresponding openings and depressions of the handle and then be held in place by the handle.

The embodiment according to the Fig. 7 to 9 differs from the embodiment according to Fig. 1 to 5 only in that the handle at its other, the end remote from the closure 220 forms a cover 58 for an optionally provided for reasons of symmetry in the thin wall 214 additional opening 61 for a closure. In the embodiment according to the Fig. 11 the handle is reduced to a flange 610 or rosette, so here is the attachment function for the closure in the center, but at the same time it also represents an optical cover of the lock cylinder device.

Of course, with appropriate tools, the handle 610 can be tackled and the door also be opened. As well as the key itself could serve to open by pulling on the key as soon as the introducer has come into the release position.

As Fig. 17B reveals, u. U. a hole pattern for the thin wall 14, in which the opening is arranged symmetrically about an axis parallel to the longitudinal extension 62 and about an axis 60 perpendicular thereto.

It should be added that the approach 22 of the fastener according to Fig. 5 a parallel to the thin wall 14 extending channel 68 forms, in which a carriage 70 against spring force 72 can be inserted, which carriage 70 at its end facing away from the spring 72 an inlet inclined surface 74 and a substantially perpendicular thereto extending retaining surface 76 has.

In the embodiments described so far, the lock housing is inserted from the outside in eg the opening 38, ie the collar 28 of the housing 26 does not need to be pushed through the opening, it remains on the outside and is by subsequent placement of the handle 10, see Fig. 5 , detained.

In the embodiment according to the Fig. 10 to 13 In contrast, a snap closure of a different type, the collar 628 can be inserted through the opening 638 from the rear, wherein a 45 degrees rotated square aperture 638 is provided in the thin wall 614, so that after passing through and after rotation of the housing by 45 Degree of breakthrough edges to hold the case when now the rosette of the closure is placed.

The Fig. 14 shows an embodiment with a breakthrough 738 with a first wide portion 80 through which the collar 728 of the housing 712 can be inserted, and a second narrow portion 82 where the collar is not passed through and held, the housing is mounted by first the collar 728 of the housing 612 is pushed through in the wide area 80 from the rear, after which a translational displacement of the housing in the narrow region 82 takes place and then the handle in the manner already described the collar in a od from the handle. Like. Einsenkunng formed rotationally rigid and axially secured against displacement.

FIGS. 15 and 16 show an H-shaped collar shape 828 and a correspondingly contoured opening 838, wherein also after passing through in accordance with Fig. 15 is moved, see Fig. 16 in which position the handle is then holding the collar, mounted.

Fig. 17A shows in a perspective view a reversible rod lock 912 with an attachable reversible adapter cage 84, which creates the rod lock a mounting collar 928 .. The adapter cage 84 is constructed so symmetrical, see also in Fig. 17C the enlarged longitudinal section through the lock case 912 with mounted cage 84 that the combination in a thin wall 914 can be used reversible. To avoid a height increase on the back of the lock case, the arrangement of the cage is adapted to the lock case 912 so that it is displaceable by the protruding measure 86. The respective unneeded part of the cage thus disappears in the already existing recessed areas of the end face of the lock case 912, see in FIG Fig. 17C the bottom.

Fig. 17B shows in perspective view the rod lock 912 of Fig. 15A with mounted cage 84, the associated aperture 938 in a thin wall 914 for mounting the adapter 84 by the insertion and displacement of its over the lock case 912 projecting part in the opening 938, and the key plate 910 for clip mounting in the ends 956 of the opening 938th and locking the adapter position by receiving the cage contour in the locked position, as far as it penetrates the opening 938 of the thin wall 914 and protrudes beyond the front side plane thereof.

Fig. 18A shows in perspective an arrangement similar to that of Fig. 17A to 17C but in a fully assembled state, namely a bar lock 1012, which surrounds by means of a here unbalanced adapter 1084 with collar 1028 edge portions of a breakthrough 1038 after passing through and moving in the opening 1038, whereupon a by means of Klipseinrichtungen 1022, 1024 in the opening 1038 fixable key plate in turn, holds the adapter 1084 in the receiving space 1030, see Fig. 18B , An enlarged axial section through the mounted in the wall 1014 key plate 1010th
